Hotel Rwanda and United 93 Analysis of Film Techniques Essay

Hotel Rwanda, directed by Terry George, is a 2004 film made depicting the Rwandan genocides. The historical context of the film is in 1994 in Rwanda, when the extremist Interahamwe militias were gathering forces to kill Tutsi tribe’s people. They succeeded for the most part, killing more than 800,000 innocent people within a hundred days. The film is shown entirely from the point of view of Paul Rusesabagina, who hosted over 1200 Rwandan refugees in his Hotel Mille Collines. The camera only leaves Paul’s situation very rarely. The effect that this has on the veracity of the film is that it shows that this story is only his story. It recreates all the emotions of unpredictability, suspense and unsureness of what’s going to happen next. For example, in one of the scenes after Paul and his family enjoy a safe night together, the next morning he wakes up with a gun to his head. However, following Paul’s situation is used more than just for dramatic value. The audience is drawn in to the film, as if they are right there with Paul, and this creates a very â€Å"real† experience. United 93 uses second-skin camera placement to achieve effectively the same result. For example, during the hijacking, you would have all noticed the jerky motion of the camera and the â€Å"imperfect†, out-of-focus shots. They illustrate the confusion in the atmosphere. Again the audience feels as if they are the person watching through the lens of the camera and that they are actually involved in the situation, thus recreating reality for the viewers. In Hotel Rwanda, footage shot of the Interahamwe beating their victims is shown. It is footage that a news reporter catches on tape in the film, but is a replica of that which another man found in reality. Additionally, Paul says that after people see the footage they will intervene. The reporter replies to him that â€Å"People will watch the footage and say, ‘Oh my god that’s horrible,’ and then they’ll go back to eating their dinners.† This quote sums up the harsh and ugly reality of the Rwandan people’s situation – that it was seen as insignificant and trivial. Similarly United 93 uses a lot of broadcasted material in the film. For  example, the coverage of the trade centres being attacked enhances the genuine nature of the film and allows the audience to remember the news coverage of the day as well. In some of the scenes in Hotel Rwanda, real Rwandan soldiers are used. Their experience brings an authenticity to the film. However, in United 93, the professionals re enact their role on the day of the attacks. For example, after the second attack, in the military, the woman had to continue giving coordinates despite the emotional turmoil and shock that she was feeling. Using real people deters from the drama of the film and brings it back to the real world where they must continue their duties in spite of whatever may happen. During almost all of Hotel Rwanda, there is the diegetic sound of gunfire in the background. Sometimes, gunfire disturbs even the most beautiful and peaceful of scenes. For example, when Paul and his wife are on the roof of the hotel enjoying a talk, they can hear and see the gunfire as they look out into the city. These kinds of intrusions constantly remind the audience of the graveness of the situation, and engage them in the atmosphere, creating a constant fear and paranoia of what will happen next. United 93 sometimes has talking in the background and never focuses on one person’s speech either. Especially in the scenes with Ben Sliney, it was sometimes difficult to tell who was talking. The people working in the background even had voices to answer to. That’s exactly what it would be like if we were there – there would be people talking over people and constant confusion. This texture of sound again adds to how genuine the film is perceived to be. Terry George and Paul Greengrass employ similar and different techniques to achieve verisimilitude in their films. Greengrass kept his movie as true to the events as possible. Terry George added in a few extra bits to add to its entertainment value, yet managed to capture the scope of the genocides very well, tell the story of Paul Rusesabagina in a credible manner, and maintain historical veracity. â€Å"Hotel Rwanda† (2004) directed by Terry George†United 93†³ (2006) directed by Gary Ross

The sculpture Bodhisattva

The sculpture Bodhisattva had the strongest impact upon me for various reasons. This piece, found in the Silk Road Chicago collection at the Art Institute of Chicago, is a cross-cultural work with obvious Eastern and Western influences. This sculpture is a beautiful 2nd to 3rd century A. D. piece that depicts a man standing in obvious deep meditation. This model was created in the region of Gandhara, which is modern-day Pakistan and Afghanistan. This early representation of a Buddha-like figure is a unique and powerful image. The title, Bodhisattva, can be directly translated from Sanskrit as meaning a â€Å"spiritual essence or being.†This figure is an interpretation of a sacred being that has delayed its own nirvana in order to help others reach the spiritual plane. The adornments that this figure wears are representative of its delay to the spiritual realm. Wearing material and worldly items means that it has not transcended yet. This type of commitment is impressive and th e figure is blessed with the incredible ability to be in a state between both worlds. The figure in the sculpture has an awe-like power over the viewer. It makes you feel as if you are looking at an object that attains holy attributes.Although, the sculpture has divine qualities, it also makes the viewer feel able to relate to it. It is humanized in a way that differs from other Buddha representations. This makes the impact of the work even stronger. An inner strength is portrayed that varies from the traditional at rest Buddha that is found in most artwork. This figure has power, but it is not menacing. It is serene and this serenity is transferred to the viewer of the piece. It is easy to see how these types of figures transcended into what is now modern-day Buddhism. The bodhisattvas were ancient spiritual beings that were worshipped.The collective group of these became the Buddha figure that is widely known today. The detail of this sculpture is incredible. Despite its age, the particulars of the piece have remained blissfully intact. The hands are missing, but it is possible to guess at how they were placed in the sculpture. The right hand was most likely raised and assuming a gesture of reassurance. An object found in the left hand would determine the type of bodhisattva. There is realism in the depiction that makes the viewer feel that they are gazing upon an actual interpretation. Unlike other bodhisattva pieces, this work feels more based on a real person.Despite the Eastern subject matter, there is little doubt that there is Western influence apparent in this piece. â€Å"The art of this region experienced a type of merger with Greek influences after Alexander the Great conquered the region in the 4th century B. C. † (Rowland, 1960, 8). An example of this found in the Bodhisattva is clear in the figure’s intricate robes. These types of folds are traditionally found in Greek and Roman artistic depictions. The drapery reminds the viewer o f the togas worn by the figures in the sculptures of Roman imperials. The chest of the figure is also reminiscent of the merger of these two cultures.It is a more realistic portrayal with the muscular indentations found upon the figure’s chest. Eastern portrayals had less defined bodies in their works. The Indian traditions of the sculpture are displayed in the figure’s mustache and the dhori that he wears. The dual influences of this work made the most significant impact upon me. It is rare to see a piece that has such obvious Eastern and Western elements found in the manifestation. This cross-cultural work is a harmonious interpretation of a strong spiritual figure. Additionally, it has a strong religious impact.It is a documentation of how Buddhism made it way from India into China. When looking at the sculpture, it is unavoidable that you are not moved at how this is exposing a historical occurrence. The stone material of the piece lends power to the idea that this is a strong figure that is tied to the material world, but has the ability to guide people to their own nirvana. The lasting material makes the viewer feel as though they are looking at a spiritual piece that has transcended through the ages. Buddha is an important figure in artwork and it is essential to know how this form came into being.

Distillation Lab Report

Data and Conclusions: The purpose of this experiment was to learn how to use distillation and gas chromatography to separate and identify different compounds from a given mixture. There are several kinds of distillation methods. However, the method that we used in this experiment was fractional distillation. This method is used when trying to separate two different volatile compounds whose boiling points differ by 40-50Â °C or more.If the boiling points are too close, this method will not work because the two compounds will begin evaporating at close temperatures and will condense down to the receiving flasks at relatively the same times. This will not create an ideal separation. The apparatus used for this type of distillation is longer than that of a simple distillation experiment because this kind of apparatus creates more efficient separation. This happens because the fractional distillation apparatus is longer, and allows for several simple distillations to occur within the col umn itself to more accurately separate liquids.The inside of the column is said to have theoretical plates, or equilibrium stages that are created by the vapor and liquid stages of a compound that create this accuracy. The column must also be insulated with cotton and aluminum to prevent any heat loss that may lead to inaccurate temperature readings or even effect the evaporation of the different compounds. When heating the stillpot, flameless heating should be used along with a magnetic stirbar. This is important to control the temperature of the mixture and keep the heat smooth and constant.Heating the mixture too fast could result in no fractionation in the column and lead to no separation. Likewise, if the mixture is heated too slowly, the vapors might now make it all the way to the condenser, and the liquid will fall back into the stillpot. If the mixture is heated correctly and constantly, the vapors should condense through a condenser and into a receiving flask. This condense r should have water running through it at all times to keep it cool and keep the condensed vapor flowing down into the receiving flask.As a whole, the entire apparatus works perfectly for two different volatile liquids with 40-50Â °C boiling point differences because as the liquid with the lower boiling point is distilled out, the higher boiling point liquid will remain in the stillpot as the other is evaporating and distilled. Then, it will be able to evaporate later as the temperature rises, after the other has more than completely distilled out. As I conducted this portion of the experiment, I noticed that while taking the three fractions, fraction A filled up the full 15 mL and continued distilling through fraction B, and eventually stopped.Because of this, I hypothesized that all of fraction A and most of fraction B consisted of the low boiling point compound. As I raised the temperature of the hotplate, I was able to collect fraction C, and I predicted that it was composed of mostly the high boiling point liquid. To test this, the experiment called for the use of gas chromatography. The chromatography would not only show the relative concentrations of each compound in the fraction, but could also help confirm the identification of the compounds we thought were in the fractions based on the temperatures that each liquid boiled.Before trying to guess the correct compounds of the mixture, one must run each individual fraction through the machine to clearly see the composition of each. Gas chromatography works because as the liquid runs through the machine, its different components run through and exit at different times due to changes of temperatures that measure high and low boiling points. The machine records these using peaks of retention time that identify these different components. After obtaining this data, there was enough information to choose a reasonable match for each of the components.Once both the fractions and the guessed compound were mixed , the retention recordings should not differ in the number of peaks because ideally the compound mixed should have the same retention time as one of the other previous peaks. If the compounds were to differ in the number of peaks, then it shows that another compound must be present with different properties. As I conducted this portion of the experiment, I guessed cyclohexane for my low boiling point liquid and toluene or heptane for my high boiling point liquid based on the fractional distillation observations.For cyclohexane I mixed it with fraction A, since it predominantly consisted of my low boiling point liquid, and observed two peaks in my results. Therefore I concluded that cyclohexane was the low boiling point liquid. However, for the second liquid I guessed heptane first, and my results showed three peaks. Knowing that I had guessed wrong, I tested toluene mixed with my fraction C and only got two peaks. The high boiling point liquid proved to be toluene. In conclusion, my results all matched the main ideas and theories presented in the experiment.From my results I was able to figure out the composition of each of the compounds in the initial mixture and compare them to those of the rest of the class. My results only varied by 3. 18%. When using the two different methods of calculating the composition, the second method using the chromatography peaks was more accurate, and compared to the first method of assuming the ideal compositions, the results differed from the class average by over 10%. Based on the consistency of our class results using the second method, the two compounds proved to have been distilled using the proper method, and is reinforced by the use of gas chromatography.

Religious Experiences and Text, Critical Analysis of Mark 10 4256 Essay

Religious Experiences and Text, Critical Analysis of Mark 10 4256 using Text Foccus Narrative Method - Essay Example Everything claimed has been inferred and interpreted by comparing what we know of the early Christian communities generally against the text itself. There are, however, broad lines of agreement on quite a few matters based upon clues found both in the text and in references to this gospel found in other exists. But undoubtedly, Mark is evidently true, being included in the most authoritative fourth-century early manuscripts (Codex Vaticanus) ( The World Book Encyclopedia , 1989). Before I go into the critical analysis of this particular passage, I will be discussing the method employed by this narrative. First, we must keep in mind that any literary analysis requires a concrete understanding of the genre it belongs to. The genre of gospels is one of the most difficult to interpret because almost all text represents both a literal and a spiritual meaning (Telford, W.R. 1995). Some gospels such as this one written by Mark, are intended to be read aloud as in a church sermon, rather than carefully studied in written form like a philosophy text ( Malbon, E. S. ,2002). This makes interpretation difficult because Biblical analyses are usually done by using written texts and typically attempt to identify large patterns of structure. For a text that is meant to be read aloud, however, what matters most are the connections that listeners make from one passage to the next. The material found in the texts of Mark must have been passed down, retold, and rearranged by mu ltiple people, but in the end someone put it into a final written form, something close to what we currently have, which bears the imprint of their own legacy skills. The author of Mark likes to use rhetorical devices, for example, repetition to highlight important ideas and a "sandwiching" technique that interweaves two different stories together in a manner that allows each to interpret and explain the other. This sandwiching technique is also called inclusion. There were two stories of healing the blind in Mark, the other story is in Mk 8:22-27. (Musso, A, Chapter 9, pg 2-3). The Gospel of Mark utilises the narrative style or method, if it will be studied according to the methods of literary critics. The narrative style or text consist of three elements namely, plot, setting, and the characters. These elements formed the basis of the narrative style of writing. In analyzing the passage of Mark 10:46-52, the plot of the story goes around a blind man named Bartimaues whose sight had been restored because of his faith. Characters in the passage includes Bartimaeus, the blind beggar, Jesus Christ who restored his sight, and the crowd present who try to silence Bartimaeus when he shouted for mercy so that Jesus would notice him. The setting of the story was a very public place in outskirt of Jericho, a town close in Jewish territory. (Musso, A, Chapter 8, pg 1, 9). Ultimately, though Mark represents the introduction of a new type of literature because nothing quite like it can be identified before early Christianity (Telford, W.R. 1995). It is very different from the collections of sayings or proverbs that can be found in other early Christian literature. Also, Mark is not meant to be a historical record of past events; instead, it is a series of events - structured in a manner to serve specific biblical goals and

Identify and discuss two nutrition problems facing america and 2 Essay

Identify and discuss two nutrition problems facing america and 2 recommendations to lwer the risk and health coasts associated with these issues - Essay Example Eating a balanced diet is a nutritional value that the Americans have ignored or do not follow, thus the rising economic and individual costs on healthcare. Past researches portrays that restaurants have increased due to the increase in demand for food and drinks from the Americans who do not like cooking and not observing the need for balanced diet. These poor nutritional habits are the cause of many deadly diseases that are expensive to maintain thus the need for the essay to discuss some of them. Obesity and diabetes are the major illnesses caused by poor nutrition habits that affect most of the American citizens and they facilitate the emergence of other chronic diseases (Duggan, Watkins, & Walker, 2008). Obesity is a body mass index (BMI) that is greater than 30 kg/m2 and it is caused by overeating and consumption of food rich in fats. Obesity and over weight is increasing at an alarming rate in the U.S. and this disease has led to the government increasing its resources on this disease to $150 billion. In the past 30 years, obesity and overweight have increased and currently more than 60% of the adults are either obese or overweight. The individual expenses have increased due to the increase of people paying to reduce weight. The increment in obesity is identical to the increment of restaurants in the U.S. since most people have adopted the consumption of fast food and Trans fats. The rate of children obesity is also in the rise since in 1974 only 5.1% of children were obese. The reports released in 2008 reveal that more than 14.6% of children were obese (Pan American Health Organization. 2010). The issue of obesity has become a global crisis. The World Health Organization (WHO) has listed it in its top ten-health crisis, and it is undertaking measures to enlighten the world on the issue of healthy nutrition. The BMI used by the WHO has been changed and

DNA Barcoding Lab Report Example | Topics and Well Written Essays - 750 words

DNA Barcoding - Lab Report Example The protocol utilizes short sequences of organisms to characterize them. These oligonucleotides fall in positions in the genome which are agreed upon and its standard for a particular genome of interest. The DNA barcode sequences are also rather short in comparison to the entire genome and can be extracted with relative ease utilizing cheap methods. For instance, the cytochrome C oxidase subunit 1 mitochondria region (COI) has in the recent times being the standard barcode region for higher animals. One define characteristic of the DNA barcode is its commonality within a species (within species) and variations among species (without species). ie for a selected DNA barcode of a particular species there exists ranging differences and these differences are minor in individuals of the same species to gurantee the sequence segment to be used as a barcode. In obtaining the DNA for branding, the mayfly should be killed in a ‘DNA friendly fashion’ by avoiding the use of preservation agents such formalin which may degrade DNA. Genomic DNA is isolated via the fast DNA extraction method from fresh or frozen specimens. Combination of Chelex protocol with Proteinase K may rule out the need for tissue disruption while guaranteeing the release of DNA leaving chitinous material left intact. PCR amplification is done with an optimal primer specific for the barcode region. The barcode products obtained from the PCR are in most instances sequences bidirectional and later deposited in the barcode reference library.

The Balkan War Of 1991-1995 Essay Example | Topics and Well Written Essays - 1500 words

The Balkan War Of 1991-1995 - Essay Example The belligerent groups in the Balkan war of 1991-1995 have been described by Gallagher (1999, p. 45), as being from diverse ideological and religious backgrounds. Some of the belligerent groups in the war had archaic and religious iconographies which included perceptions of being the elect, holy, most ancient, heavenly and sacred. As a result there were beliefs among the warring groups that they had a mission to fulfil which came from God. Glenny (1993, p. 211) reveals that the historic military crusades of various cultured nations and dictators who were declared to be chosen illustrates how religion can influence development of war. The religious traditions of the warring groups in the Balkans war and their impact on democracy and political policies are therefore blamed for the fighting in the Croatian region. During the war, fighters were motivated by the need to protect their religious identity against adversaries who were considered a threat to their beliefs and national heritage . As demonstrated by Denitch (1994, p. 24) the final analysis of the Balkan war of 1991-1995 shows that it was a religious war. Although the war has been attributed to the consequences of differences in culture, incompatible national policies and revenge for previous injustices, religion had a big role in the development of the war. Because the happenings which led to this war were spontaneous, unreasonable and irrational, the role of religion in the fighting is justifiable.

Reflection on the film 12 Angry Men Research Paper

Reflection on the film 12 Angry Men - Research Paper Example Reflection on the film 12 Angry Men The problem of prejudice and the difficulty faced by the jurors in decision making process is still an unresolved problem in the global context. In the beginning, most of the jurors were against the culprit. In the end, all the jurors came to know that their decision is based upon their personal opinions on the immigrant population. My personal opinion/reflection on the film 12 Angry Men is divided into three sections: prejudice, racial supremacy, and misuse of law. Prejudice I am of the opinion that the director made use of the protagonist (the immigrant boy, probably from Puerto Rican Island) to unmask the depth of prejudice against immigrants in America. I believe that prejudice based upon racial and cultural identity is an important problem faced by a member who belongs to an immigrant community. If we are not from an immigrant community, there exists less possibility to have deeper understanding on this problem. Within this context, the director makes use of the protagonist as a medium to express his opinion on the problem faced by immigrants. In the beginning of the film, the jury, which consists of 12 members, does not show any particular interest in the emotional trauma faced by the boy. Biskind (2001) made clear that, â€Å"In the view of the strong case against the defendant, it is not too surprising that the jury’s first straw vote comes out 11 to 1 for conviction† (p.11). ... So, in my opinion, the film portrays how prejudice affects the smooth functioning of law and order in a modern society. Racial superiority I think racial superiority is a myth based upon false opinion, not upon fact. The elite class in the society considers that their status in the society is indebted to their racial identity. But one cannot prove that racial identity determines one’s superiority over others. So, I am totally against racial superiority. One of the factors which attracted me towards this film is the director’s attempt to expose that racial superiority is a myth. In the film, the boy is the victim of racial superiority/racial supremacy. For instance, most of the members of the jury are white middle class men. Still, all the members are from different layers of the society. Most of them do not try to allow the boy to prove his innocence. On the other side, juror 8, an architect by profession, is not ready to act against the boy. Later, some of the jurors l ike Juror 5 and Juror 11 decide to change their opinion. Still, Juror 3’s wavering nature hinders the jury members to have a unanimous decision. In the film, most of the jury members are not aware of their role in decision making process because they act according to the false beliefs in the society. One can see that most of the jury members are middle aged and their personal opinions on the immigrants deeply influence their decisions. So, the film helped me to know more about the problem of prejudice based upon racial superiority. Misuse of law I consider this film as an eye-opener to those who believe that death penalty can reduce crime in the society. On the other side, law is misused to victimize innocent individuals who are not

Genetically Modified Food is bad Essay Example for Free

Genetically Modified Food is bad Essay The debate on whether genetically modified foods are safe for human consumption is marked with controversy in the political, social, academic, and economic fronts of our community. Proponents of genetically modified foods claim that it is the only viable solution to the food insecurity problem that is eminent in the global community (Roth, 2000). Some scientific research findings have claimed that genetically modified foods have substantial levels of safety for human consumption. Nevertheless, the long term health safety of genetically modified foods has never been confirmed (Atherton, 2002). Despite the numerous claims made by proponents of genetically modified foods, there has been not concrete evidence to qualify such claim, a factor that makes consumption of such foods a risk to the human health. Genetically modified foods have been evidently closely associated with some long term health complications (Atherton, 2002). According to available statistical evidence, the global community is witnessing an increase in the occurrences of terminal diseases such as obesity. This trend has been closely attributed to the ever increasing usage of genetically modified foods in the community (Roth, 2000). Records have shown that thousands of thousands of Americans have fallen victims of obesity. Indeed, this health problem has become an issue of national concern in the American society. According to scientist, the problem has been escalated by the common trends of Americans in using fast foods. This is because, such foods lack fiber components, which are crucial to the human body. Another reason given is that such foods contain high levels of energy, which are usually not necessary to the body. Therefore, genetically modified foods are no doubt a leading cause of the increasing numbers of obese people in the community. Although numerous scientific research finding claim substantial health safety for the consumption of genetically modified foods, no search has been conducted to qualify the potential long term health risk brought by such foods (Karlsson, 2003). It has been established that gene modification can result into totally different type of gene whose impact in the human body can not be predicted. Based on this reasoning it is certain that genetically modified foods cannot be claimed safe unless sufficient research has been conducted. Still on the question of safety is the fact that modified genes are commonly made using denatured toxins, which serve to make the foods more robust to infections (Roth, 2000). According to scientific claims, these toxins are in essence poisonous to the human body cells upon long term accumulation (Roth, 2000). In fact this is what has been identified as potential allergens in genetically modified foods which make some people susceptible to their consumption. In conclusion therefore, genetically modified foods are a potential risk to the sustainable health of the human community. We are no doubt experiencing the impact such have from the ever increasing illnesses such as cases of obesity in the community. Since the question of the long term safety of these foods to the human body are significantly eminent, biotechnology products should be regarded as an issue of concern for the long term social and economic development of the community. Just as is rightly claimed, with the available natural resources and modern technological advancements, the world is capable of supplying its population with sufficient food (Roth, 2000). Therefore, any claim of genetically modified foods being the only solution to the world food security is misleading. It only serves as an indication of ignorance and lack of concern for the sustainable future of the human community. References Atherton, K. (2002). Genetically Modified Crops: Assessing Safety.

Theory Mild Steel Material

Theory Mild Steel Material Mild steel or so-called carbon steel was the most common  types of steel  being used nowadays in almost all forms of industrial applications and industrial manufacturing. Basically, it refers to a group of low carbon steel with relatively low tensile strength, malleable and cheap which consist the maximum composition of Carbon between 0.15% to 0.3%. Furthermore its surface hardness can be increased through carburizing. Apart from the cheapest types of steel, it was widely used in every type of product created from  steel because of its weldability, good strength and hardness and although it has the tendency to rust, it is very durable to build materials. Plus, it had the ability to be be magnetized and used in almost any project that requires a lot number of metal. 2.1.2 Types of Mild Steel There were many types of Mild Steel that had been discovered until recently, among them were A36, High Strength Low Alloy (HSLA) Steel, Abrasion Resistant (AR), Pressure Vessel Quality (PVQ), 4140, 8620 ,1045,1018 and Free Machine Steel (FM 45). The most popular mild steel specification for carbon steel is A36 which normally comes in shapes of plates and bars for bolted and welded construction. High Strength Low Alloy (HSLA) Steel usually contain more than 15% composition of carbon and it is stronger than any ordinary plain carbon steels. HSLA normally comes in the appearance of Corten and Exten material. They are widely used in cars, cranes, bridges and other structures to handle stress at low temperatures. Abrasion Resistant (AR) is commonly used in truck and hopper bodies, shoots, and wear as it is a very hard mild steel that is abrasion or wear resistant. While for the Pressure Vessel Quality (PVQ), because of its properties which are high strength and low weight mild steel it wa s commonly used in earth moving, transport equipment such as booms, buckets, and pressure vessels. Among the example of PVQ are A514 and T1. 4140 and 8620 perform well under high heat, heavy load wear-resistant material and was used for dyes and molds. 1045 is a standard mild steel which is more durable than A36 though it is harder to machine and weld. It is commonly used for axles, bolts, connecting rods, hydraulic rams and etc. 1018 is the most frequently available of the cold-rolled steels and chemically similar to A36. It come generally in round rod, square bar and rectangle bar. It have good edges such as strength, ductility and ease of machining. Last but not least, Free Machine Steel (FM 45) is a mild steel that has average durability in strength and easy to machine. 2.1.3 Mechanical Properties of Mild Steel In materials science, the strength phrase can be assumed as a high resistance to breakage. Mild steel was well known because of its high resistance to breakage and therefore its mechanical properties can be considered as very strong due to the low amount of carbon it contains. Mild Steel also was recognized as having a high tensile and impact strength compared to the High Carbon Steel due to the fact that it can be easily malleable even when in cold. Another distinguished differences of mechanical properties between high carbon steel and Mild Steel was mild steel bends or deforms if being subjected under stress while a high carbon steels usually shatter or crack. This cause Mild Steel was widely preferred in the construction area in the interest of its weldability, machiniability, malleablility and high strength. As a result of its high strength and easy to malleable, the former is actually quite soft which cause its easy to machine and welding both to itself or to other types of ste el. Nevertheless, the former cannot be hardened through heat treatment processes unlike the latter. Mild steel usually contains few other alloying elements other than Carbon to give them certain desirable mechanical properties. For example, lets take a look at 1018, a common type of mild steel. 1018 contains an approximately 0.6%-0.9% Manganese (Mn), 0.04% Phosphorus and 0.05% Sulphur. Varying these chemicals will affects certain properties such as corrosion resistance and strength. For instance, Phosphorus, Sulphur and Silicon are undesirable and can be considered as trace elements as they have negative impacts on the steel due to their bad effects on the steel and its properties. The reason why Phosphorus is consider as a trace element because it affects primarily the ductility and the toughness of steel mostly when the steel is in the quenched and tempered conditions. In fact, the Phosphorus has a tendency to react with the iron to form a compound known as ironphosphide (Fe3P) which has the particularity of being brittle. Hence, phosphorus renders steel less tough and ductile wh ile it increases brittleness. While for the Sulphur which also was a trace element, it has a great tendency to segregate (that is to isolate itself in the structure). It also reacts with iron to form iron sulphide which produces red or hot-shortness, since the low melting eutectic forms a network around the grains so that these hold but loosely together, and the grain boundaries may easily break up during hotforming. So, from here we can see that Sulphur plays a great role in the decline ability of steel such as weldability, impact, toughness and the ductility of the steel. Carbon is an element whose presence is imperative in all steel. Indeed, carbon is the principle hardening element of steel. That is, this alloying element determines the level of hardness or strength that can be attained by quenching. Furthermore, carbon is essential for the formation of cementite (as well as other carbides) and of pearlite, spheridite, bainite, and iron-carbon martensite, with martensite being the hardest of the microstructures. Carbon is also responsible for increase in tensile strength, hardness, resistance to wear and abrasion. However, when present in high quantities it affects the ductility, the toughness and the machinability of steel. Whereas element like Carbon and Manganese are desireable as it can enhanced the properties of steel. First, lets observe Carbon element. Carbon is an element whose presence is imperative in all steel. Indeed, carbon is the principle hardening element of steel. That means that the alloying element determines the level of hardness or strength that can be attained by quenching. Furthermore, carbon is essential for the formation of cementite (as well as other carbides) and not to mention pearlite, spheridite,bainite, and iron-carbon martensite, with martensite being the hardest of the microstructures. Carbon is also responsible for the increase in tensile strength, hardness,resistance to wear and abrasion. However, when present in high quantities it will affects the ductility, the toughness and the machinability of steel. Same as Carbon, Manganese also contributes greatly towards increasing strength and hardness, but to a less extent than carbon. To be more precise, the degree to which manganese increases hardness and strength is dependent upon the Carbon content of the steel. In fact, manganese contributes to the increasing the strength of the ferrite, and also toward increasing the hardness of penetration of steel in the quench by decreasing the critical quenching speed. Moreover, still consisting of a considerable amount of manganese can be quenched in oil rather than in water, and are therefore less susceptible to cracking because of reduction in the shock of the quenching. In addition, the latter enhance the tensile strength, the hardness, the harden ability, the resistance to wear and it also increase the rate of carbon penetrating in the coefficient of thermal expansion of steel whereas it is detrimental to both thermal and electrical conductivity. 2.1.4 Application of Mild Steel Nowadays, every objects that are fabricated of  steel  are using  mild  steel type of material which includes automobile chassis, motorcycle frames and most cookware product. Due to its poor corrosion-resistance, it must be painted or protected and sealed in order to prevent rust from damaging it. A light coat of oil or grease is able to seal this  steel  and aid in rust control.Unlike high-carbon  steel,  mild  steel  is easily welded. The properties of the  steel  allow the electrical current to travel through the metal without distorting the makeup of the material. Some types of high-carbon  steel such as stainless  steel, require special techniques in order to properly weld the material. Being less brittle than high-carbon steels, the  mild  variant is able to flex and give in construction projects where a higher-carbon version could simply break. Most of the pipeline in the world is created using  mild  steel. This allows the pipe to not only be easily welded into place, but also lets the pipeline flex and avoid cracking and breaking under pressure. The corrosive properties of the  steel  pipeline mean that it must be properly sealed through painting or a process often used on pipelines that involves wrapping the pipe with a corrosive-resistant material.Often in very cold climates, a warming type of insulating material is wrapped around the pipeline. This material helps keep the cold inside the pipe running smoothly. The wrap also prevents the soft  mild  pipe  steel  from becoming brittle and cracking. The constant expansion and shrinkage due to cold and warmth cycling in the pipe could create structural integrity problems, but these are held in check by the insulating wrap. On a much smaller scale, household pipes can be prevented from becoming cold and breaking by the use of electrical heating tape. 2.2 Theory Test 2.2.1 Tensile Test A  tensile test, also known as tension test is the most fundamental type of mechanical test one can perform on the material. This tests are simple, relatively inexpensive, and fully standardized. By pulling on something, one will determine how the material will react to forces being applied in tension. As the material is being pulled, one will find its strength along with how much it will elongate. The objective of conducting Tensile test until the material breaks or rupture is to obtain a complete tensile profile. A curve will result showing how it reacted to the forces being applied. The point of failure is of much interest and is typically called the Ultimate Strength or UTS on the Stress vs Strain diagram. The total of 4 samples of mild steel plate were prepared for this test purposed where all the samples were machined following the standardized dimension given. Stress vs Strain Diagram 2.2.2 Hardness Test Rockwell hardness testing is a general method for measuring the bulk hardness of metallic and polymer materials. Although hardness testing does not give a direct measurement of any performance properties, hardness correlates with strength, wear resistance, and other properties. Hardness testing is widely used for material evaluation due to its simplicity and low cost relative to direct measurement of many properties. This method consists of indenting the test material with a diamond cone or hardened steel ball indenter. Only 1 samples of mild steel material plate was prepared for this type of test as this test only required 1 samples indent 10 data on that 1 samples. 2.2.3 Impact Test The impact properties of samples were measured using the standardized dimension from the strength lab that had been acquired from the lab technician. Then the samples that had complete the machining process will have to undergo two test which are Charpy test and Izod test. These two test were meant to measure the the amount of  energy absorbed by a material during  fracture. This absorbed energy is a measure of a given materials notch  toughness  and acts as a tool to study temperature-dependent ductile-brittle transition. The only distinctive differences between the charpy and izod lies in the way that the specimen are supported in the apparatus machine. 2.2.4 Microstructure Observation In Microstructure observation, the samples of mild steel plate will be observed under the microscope in order to monitor the microstructure of the specimen. Before the observation start, the sample will have to be prepared by first grinding the sample with grit sand paper starting from 240, 320, 400, 600 and lastly 1200. After that the sample will be polished by using either powder or paste depend on which is more suitable. Only after all these process were done we can start observe the microstructure under the microscope starting from 5x, 10x, 20x, 40x, 50x and etc.

Quality Assessment System in Construction

Quality Assessment System in Construction 1.0 Introduction Quality assessment system in construction industry is a system or method to measure and evaluate the quality of workmanship of a construction work based on the relevant approved standard. This assessment sets out the standard on quality of workmanship for various construction elements of building and infrastructure construction work. The quality of workmanship of a construction work is assessed according to the requirement of the relevant standard, and marks are awarded if the workmanship complies with the standard, (CIDB, 2011). According to Wong, (2007), one of the hallmarks of a developed construction industry is in the output of quality buildings and structures. It is therefore critical to inculcate among professionals, contractors and end-users the awareness of quality products and good designs, not only to raise the standard of the industrys products, but also to reduce wastage arising from rework. The Quality Assessment System in Construction (QLASSIC) developed by CIDB is an independent method to measure and evaluate the quality of workmanship and finishes of construction works based on objective comparison through a sampling and statistical approach. The Malaysian construction industry stakeholders are looking forward to action plans by CIDB in implementing QLASSIC with incentives as has been the case for the Construction Quality Assessment System (CONQUAS) in Singapore. Mahmood. et al. (2010) stated the quality management system is being increasingly applied to the construction company to solve quality problem. The implementation of this system required a culture change and change in management behaviour. The organization need to shift from their current culture to a quality management system culture that focuses on quality as a key strategy. A review of literature identifies ten important culture elements that contribute to successful implementation of quality management system, which include leadership and top management commitment, customer management, training and education, teamwork, people management and empowerment, supplier partnership, quality planning and strategic, process management, rewards and recognition and effective communication. 2.0 Problem Statements Nowadays, the quality of the building becomes an issue when many accidents occurred related to the building failure such as building collapse. Many criticisms received from public about this quality of the building. This has proven when Mahmood et al. (2010) stated that construction industry in Malaysia has been viewed as one of the sectors that have a poor quality compared to other sectors such as agriculture or automotive sector. This is supported by Said et. al. (2009) when he claims that there were misunderstandings among the organization player on Quality Management System (QMS) concepts has become a stumbling block for its successful implementation. Said et. al (2010, c.f SIRIM 2005) also found that QMS could be implemented either at the organization level or at the project level itself. Looking at the construction industry scenario in Malaysia, there are approximately 4000 ISO 9001:2000 QMS certified organizations in the Malaysian construction related industry. However, the number is still relatively small when compared to the total number of 63,204 organizations in this industry. Looking at the current scenario in the Malaysian construction industry, QMS compliance is a required factor to improve the quality of the Malaysian Construction Industry. Keng and Hamzah (2011, c.f Haupt et al. 2004) also found several problems found in implementing the quality assessment system on construction site such as too much paperwork, transient nature of workforce, field employees regard quality management as irrelevant, difficulty in measuring results, and subcontractors and suppliers not interested in assessment 3.0 Aim and Objectives of the Study The aim of this research is to study the impacts of implementation of quality assessment system in construction projects. Objectives: To identify the advantages from implementation of Quality Assessment System in Construction (QLASSIC) system in construction project. To determine the challenges in implementing quality assessment system in construction project. 4.0 Scope and Limitation Among the parties involved in construction, the contractors are the one who know the real situation in the construction compared to others. Beside that, the contractors also know the whole process in construction starting site possession until the projects is completed. Therefore, this research will be conducted with focusing: Only to contractor G6 or G7 (CIDB) that already engaged with high cost construction project that focus on quality of the building and clients satisfaction as a main priority. The limitation of the research survey only focus on Klang Valley area because this area was highly developed with new buildings design. 5.0 Research Methodology Primary Data A set of questionnaire will distribute to collect valuable data for this research. This interview may conduct to the targeted group in construction projects or organization. Secondary Data The researcher found literature review as his secondary resources with aim to investigate the previous research and body of knowledge about the quality assessment system in Malaysian construction industry. Problem statement Objective 2 To determine the challenges in implementing quality assessment system in construction project. Objective 1 To identify the advantages from implementation of Quality Assessment System in Construction (QLASSIC) system in construction project. Literature review Questionnaire Case study Comments and conclusion Impacts of implementation of quality assessment system in construction projects. Figure 1.1: flow chart of research process CHAPTER II:Â  LITERATURE REVIEW 2.1 Quality Assessment in Construction (QLASSIC) 2.1.1 Introduction According to CIDB (2006), Quality Assessment System for Building Construction Work (QLASSIC) is an independent method to assess and evaluate the quality of workmanship of building projects based on the standard stated as a guideline. Yin (2012), added that Quality Assessment System in Construction (QLASSIC) is a system to measure and evaluate the quality of workmanship of a construction work based on the relevant approved standard. QLASSIC enables the quality of workmanship between construction projects to be objectively compared through a scoring system. The purpose of this scheme is to enable a construction project to be undergone in standard of procedure in order to ensure the quality of workmanship in the works The construction industry and the private sector plays an important role in creating wealth and improving the quality of life of Malaysians through interpretation of socio-economic policy of the governments social and economic infrastructure and buildings. In addition, the construction industry creates multiplier effects to other industries, including manufacturing, financial services, and professional services. The Construction Industry Development Board (CIDB) (2006), has published a special guideline for measuring the quality of construction and become As a parameter for the level of quality achieved in a construction project in Malaysia. Rating of the workmanship will be made through site inspections. Assessments will be conducted by a qualified evaluator of QLASSIC registered, trained and have passed the training conducted by the CIDB 2.1.2 Objectives of QLASSIC Masters Builders Association Malaysia (MBAM) (2006), stated that CIDB list down objectives of the QLASSIC system: To elevate the level of quality in the construction industry. To have a standard quality assessment system as a benchmark for quality of construction works. To assist contractors to achieve defect-free when carrying out construction work. To be used as criteria to evaluate the performance of contractors based on quality of workmanship. To be used for data compilation for statistical analysis in estimating the level of quality and productivity of the construction industry. 2.1.3 Scopes of QLASSIC CIDB (2006), stated that this assessment is set out for the quality of workmanship for the various aspects of the construction elements for the general building works. It will cover four main components which is, Structural works, Architectural works, Mechanical and Electrical (M E) works and External works. Assessments on the workmanship are carried out based on this standard and marks are awarded if the workmanship complies with the standards. These marks are then summed up to give a total quality score (%) for the building project. However, the assessment excludes works such as piling, foundation and sub-structure works which are heavily equipment-based and called under separate contracts or sub contracts. The building is assessed primarily on workmanship standards achieved through site inspection and field testing. The assessment is done throughout the construction process for structural and M E works. For completed building projects the assessment is done for architectural, M E fittings and external works. Apart from site inspection, the assessment also includes field tests, test results on the material and the functional performance of selected services and installations. These tests help to safeguard the interest of building occupants in relation to safety, comfort and aesthetic; these defects may surface only after sometime. In addition, MBAM (2006), stated that QLASSIC sets out the standards for various construction elements in building work and other infrastructure work. The quality assessment on the workmanship and finishes of the construction work is based on these standards and points are awarded if the workmanship and finishes comply with the standards. These points are then summed up to give a total quality score called the QLASSIC Score (%) for a project. The assessment is conducted at the construction site through inspection and field testing. The score will be done on construction works that are inspected for the first time. Construction works that are rectified and corrected after the assessment will not be rescored. The objective of this practice is to encourage contractors to do things right the first time and every time 2.1.4 Components to be assessed According to QLASSIC (2006), the quality standards for building construction work are divided into four main components:- a) Structural works The structural integrity of the building is of paramount importance as the cost of failure and repairs are very significant. The assessment of structural works comprises: Site inspection of formwork, steel reinforcement, prefabricated or pre-cast elements, etc. during construction. Laboratory testing of compressive strength of concrete and tensile strength of steel reinforcement. Non-destructive testing of the uniformity and the cover of hardened concrete. b) Architectural works Architectural works deal mainly with the finishes. This is the part where the quality and standards of workmanship are most visible. Architectural works are works such as floors, internal walls, ceiling, door and window, fixtures and fittings, external wall, roofs, driveway, porch and apron. c) Mechanical and Electrical (M E) works The quality of M E works is important in view of its increasingly high cost proportion and its impact on the performance of a building. The assessment covers electrical works, air-conditioning and mechanical ventilation works (ACMV), fire protection works, sanitary and plumbing works, lifts, escalator and other basic M E fittings. d) External works External works cover the general external work elements in building construction such as the linkways/ shelters, drains, road works, car parks, footpaths, turfings, playgrounds, gates and fences, swimming pools, hardscapes and electrical substation. 2.1.5 Assessment approach In general, the assessor determines the samples or elements to be assessed to each assessment. The samples are selected from drawings and plans. The selected samples shall be distributed as uniformly as possible throughout the project and construction stages. All locations are to be offered for the assessment. The scoring will be done on the works that are inspected for the first time. When an assessed item does not comply with the corresponding QLASSIC standards, it is considered failed and an X will be noted in the assessment form. Likewise a v is given for an item meeting the standards. A - will be given to indicate that the item is not applicable. The score is computed based on the number of v over the total number of items assessed. (CIDB, 2006) MBAM (2006) stated that, it is impractical to assess all elements in a construction project, QLASSIC assessment uses a sampling process to carry out the assessment. The samples are selected from drawings and plans of the relevant construction project. a) Structural Works The assessment is carried out throughout the various construction stages. The numbers of samples are determined based on the gross floor area (GFA) of the building with a minimum and maximum number of samples. b) Architectural works The assessment is carried out upon completion of the building project and before handing over of the project. The samples are determined based on the gross floor area (GFA) of the building with a minimum and maximum number of samples. c) Mechanical and Electrical (M E) works The samples are determined based on the gross floor area (GFA) of the building with a minimum and maximum number of samples. For completed projects the assessment is carried out upon completion of the building project and before handing over of the project. For projects in progress the assessment is carried out throughout the various construction stages. d) External works The assessment is carried out upon completion of the building and before handing over of the project. The numbers of samples are determined based on (10m length section/ location) with a minimum number of samples. 2.1.6 Evaluation process of QLASSIC START Architectural work Structural work ME work External work Developers / contractors shall made application APPLY TO CIDB SCOPE OF EVALUATION Numbers of sample is based on guideline in CIS7 Samples are identified before assessors make an evaluation SAMPLING FROM ASSESSOR Qualified assessors will assess the samples. The quality standard based on CIS7. SAMPLING ON SITE QLASSIC SCORE (%) Report from CIDB based on the evaluation by assessors. FINISH 2.1.7 QLASSIC assessor To be an assessor, the persons must attend the QLASSIC training course before being qualified to carry out the actual assessment at the construction sites. The QLASSIC assessors are continuously updated to ensure consistency and effective implementation of the assessment. Requirements of QLASSIC assessor; Malaysian citizen Age: 25-60 years Possesses an academic qualification in construction related fields such as architectural/civil/mechanical/electrical engineering/quantity surveyor or other fields Successfully completed the QLASSIC Assessor Certification Programme. Posses minimum working experience in the construction industry according to academic qualification as follows. 2.2 Quality philosophy 2.2.1 Quality concept Many definitions had been made in order to explain the terms of quality. Hoyle (1998), defined quality as a degree of excellence, conformance with requirements, the totally of characteristic of an entity that bear its ability to satisfy stated or implied needs, fitness for use. In addition, he also stated quality as freedom from defects, imperfections or contamination. In other words, quality is focus on satisfaction needs and costumers demand as a first priority. In construction industry, the offer from clients to contractor to do projects with a terms and conditions need to be followed by contractors and if the projects is completed according the requirements given is a quality products. According to Besterfield (1998), quality cannot be measured by with number or it intangible and it only can be measure by personnel perception. Quality only can be quantified as follows: Q = P/E Where, Q=Quality P=Performance E=Expectations According to the formula, if quality is greater, the costumer has a good feeling about the products deliver. 2.2.2 Quality parameter According to Hoyle (1998), difference in design can be classified or group into different class and the results can be good or poor. It is not enough to produce product only conform to the specification or supply services that meet managements requirement. Quality can be classified in three parameters which is: Quality of design is the extent to which the design reflects a product or services that satisfies costumer needs. All the necessary characteristics need to be designed into the product or service at the outset. Quality of conformance is the extent to which the product or service conform to the design standard. The design has faithfully translating the clients need and it depends on the processes to realize the design into an actual end products. Quality of use is the extent which the user able to secure continuity of use from the product or service. Products need to have a low cost of ownership be safe and reliable and maintainable in use. 2.2.3 Quality management According to Juran (1989), basic purpose of quality management is to eliminate failure in services or products. Failure not only that products, process or services but it would be fail in their function or their function not satisfy to customer demand. Hence, the quality management consist of planning, organizing, controlling and preventing the products or services from failure. All the methods and technique that use in quality management must be useful to improve and increase the quality of the products or services. This quality management include inspection process. Inspection is a process where quality is measured before deliver the products or services to the costumer. However, inspection alone is not enough to deliver quality products or services, it must adopt with the other practice to prevent failure. Quality management is both technical and behavioural subject. Therefore, the management of quality involves many aspects of an organization and the organization must make sure all its function inter-related and work efficiently and effectively because whenever any function fail to perform, they will effect to another. 2.2.4 Quality control Quality control is the operational activities or techniques used to fulfil the requirement for quality. In other words, it is a process to maintain standards and prevent from failure. Standard can be control by process of selection, measurement and correction of work. Quality control can be applied in the processes that produce products by measuring the overall quality performance of the organization.(Juran, 1989) There are steps to control the quality; Determine what elements need to be controlled. Determine whether it needs to be control before, during or after the result. Establish details for the parameter to be controlled. Establish plans for control which specify the means by which the characteristics will be achieved and variation detected and removed. Organize resource to implement the quality control. Install sensor at an appropriate point in the process. Collect the data. Analyze the results. Propose solutions and decide the technique to overcome the problems. Take the action and check again whether it has been corrected or not. 2.2.5 Quality improvement Quality improvement can be defined as an action taken by the organization to increase and improve the effectiveness of activities or processes to provide satisfaction to the costumer. (ISO,2000). In other words, process of changing the quality for the products or services that can improve the level of satisfaction to the costumer. This can be done by control or increase the standard. Control approach can be done by improving the rate at which an agreed standard is achieved. The second approach is by increase the standard and setting new level. New standard can be created by making research and development to a products and services. 2.2.6 Quality assurance ISO (2000), defined the quality assurance as a planned and systematic action necessary to provide adequate confidence that an entity will fulfil the requirements for quality. Costumers and managers need a quality assurance, as they cannot oversee the operation for themselves. The assurance of quality can be gained by testing a products or services against prescribed standards to establish in capability to meet them. This approach can give confidence only to the tested products. Quality assurance not controls the quality, it establish the extent to which quality will be, is being or has been controlled. 2.2.7 Quality system Hoyle (1998), stated that system is a set of function or activities that operate together to achieve the aim. A success quality system will lead the organization to achieve, sustain and improve the quality. It is a planning, well evaluates and organized to produce a required quality performance. A quality system is the approach to achieve all desire quality goals. Quality system focus on the quality of the organization produces, the factors which will cause the organization to achieve its goals, the factors influencing the customer satisfaction and identify nonconforming product. Quality system needs to possess certain characteristics for them to be fit for their purpose. Robustness ability to withstand variation in the way operation are carried out without failure Complexity the number of interconnections, routings, pathways, variations, options, etc, which give rise multiple procedure. Maintainability the ease and economy with which system changes can be made. Flexibility ability of the system can handle the changes in circumstances. Consistency the ability of the documented system unifies communication both within itself and the organizations. 2.3 Challenges faced by construction project team in implementation of QLASSIC 2.3.1 Introduction CIDB (2008) stated that like any other countries around the world, Malaysian construction industries face the problems that affect the development of construction sector. If these problems not managed and addressed effectively it become worst. The construction sector will continue play an important role as a main contributor to the Malaysia economy. To make sure the construction sector become stronger, Malaysia introduced many ways and one of the ways by introducing the QLASSIC system by CIDB. Although it was introduced several years ago, the implementations of this system still not achieve the target. Only few projects were applied this system. This because there are few problems and challenges regarding implementing this system faced by construction team. 2.3.2 Fragmentation and Disintegration of the Construction Industry The construction industry has remained a very fragmented industry where different activities in the entire value chain of the construction processes are being undertaken by different parties, often undertaken in isolation, thus resulting in inefficiencies. In particular, the segregation of design and construction activities which is widely practiced does not encourage consideration for factors like savings in labour utilisation, ease of maintenance, construction safety and the practicality of construction methods.(CIDB,2008) As a result of the lack of such integration considerations in the industry, the process to implement the QLASSIC system to the construction projects is difficult. The different players are also become conflict and the implementation of this system become unsuccessful. This because there are many parties involved in construction projects. Thus, some of the parties will implement the system and some are not. So, the systems are not applied on the overall parts or elements that need to be assess in the construction projects. 2.3.3 Foreign labour Labour-intensive conventional methods of construction that are still prevalent in Malaysia. The adoption of such methods are encouraged by the cheaper cost of employment of foreign workers with lower wages and the availability of such workers for short-term periods of work.. Another reason for the heavy dependency on foreign labour involves the fact that the local workforce is reluctant to be employed as construction workers in the wet trades, where the image of the construction industry has always been one that is Dirty, Dangerous and Difficult. (CIDB, 2008) As a result, the implementation of QLASSIC system in construction projects becomes a problem because foreign workers do not understand this system. They are not expose about this system by the authorities. Thus, it become challenges for construction team to make sure the construction projects meet the standard that need in the QLASSIC system. 2.3.4 Lack of RD CIDB (2008) mentioned, the local construction industry is characterised as one that is labour-intensive, which has resulted in numerous challenges as highlighted previously. There is a need for the construction industry to progress towards one that is more focused on innovation and automation. However, the pace of innovation through RD and automation through the adoption of new construction methods are relatively low due to the abundance of cheap foreign labour. Despite the lack of RD initiatives in the Malaysian construction industry, there has been progress on the local front to encourage and stimulate RD activities in the construction industry. As a result, one of the factor this system did not get attention from construction team is because lack of RD. Before this system introduced to the construction sector, the responsible authorities that doing this research must make sure that the information gather from the research is enough and the opinion from all the parties involved in construction project is taking into consideration. This is because the construction parties are the main target as they will use this system. So, opinion from construction parties is the first priority to suite with construction projects when implementation this system. 2.4 Effective strategies in implementing QLASSIC 2.4.1 Stepping up research and development Wong (2007), stated that Research and Development (RD) is critical to productivity and quality. Improvements in the construction industry such as better materials, more cost-effective design and construction methods and labour-saving equipment are often introduced by way of RD initiative. However, for RD to be useful there is a need to ensure that new technologies and capabilities are efficiently shared and adopted by players in the industry to enhance the quality of the building. At the present moment, the amount of Malaysian construction RD ranges from negligible to non-existent. On the other hand, RD conducted by local institution of higher learning is often perceived as not been able to meet industry needs. Hence, there is a need for stronger collaboration between academia and the industry in stimulating RD efforts in order to produce quality of the building. 2.4.2 Raising the Skills Level According to Wong (2007), the reality is that so long as the industry has a ready access to a large number of foreign workers, there is very little incentive for the industry to upgrade itself. While recognizing that the industry will continue to rely on foreign workers in the near and medium term, there is a need to reduce the number of unskilled foreign workers. CIDB, in collaboration with the National Vocational Training Council of Malaysia (MLVKM) ha s developed the National Occupational Skill Standards (NOSS) for the construction industry, for the purpose of developing skilled manpower in the industry by development of training module for the various trades as well as for skill accreditation for career development of construction personnel. The Malaysian construction industry at present is largely dependent on low skilled foreign workers. As introduce new technologies and push for higher quality the demand for manpower especially foreign workers should be reduced. 2.4.3 Enhancing professionalism Enhancing professionalism of the industry can be achieved at three levels, namely the individual, trade association or professional institution, and the industry. At the individual level, the curriculum of institution of higher learning should be enhanced to include common modules and soft skills. At trade association or professional institution level, Continuing Professional Development (CPD) Programme should be made mandatory for the renewal of professional membership as is currently practised by the Board of Engineers Malaysia (BEM), Board of Architect Malaysia (BAM) and Board of Quantity Surveyors Malaysia (BQSM). To synchronize professional practice and thinking, it is also necessary for each profession to draw up its own set of code of conduct. (Wong, 2007) This will help to lay the foundation for constructional skills needed for construction players. Hence it must constantly promote, recognise and reward creativity, quality work, and innovation to integrate the various processes in the industry, but also to project a more progressive image. 2.4.4 Training and Education Firms that establish workplace education programmes report noticeable improvements in their workers abilities and the quality of their products (Cebeci and Beskese, 2002). The importance of training is to ensure that the skills of the workforce do not become obsolete in an environment of change and an understanding and attitude of quality is developed and maintained. Training should be directed at all levels of the organization to understand the QLASSIC process. 2.4.5 Integrated approach to construction According to Wong (2007), the construction industry is highly fragmented due to the sequential nature of the construction process. One of the major causes of low productivity and quality is the lack of integration of activities across the construction value chain. Consequently, mistakes in the construction stage resulting low quality of the building. So, through integration focus on effective interpersonal relationships, jointly planned work, identifying and solving problems will produce better quality. QLASSIC is one of the methods that need the integration by all the construction players to implement it. 2.4.6 Rewards and recognition An important feature of any quality improvement programme is showing due recognition for improved performance by any individual, section, and department or division within the company considers recognition as one of the most important steps of the quality improvement proce

Edification or False Idolatry in Emerson's The American Scholar  Ã‚  Ã‚  Ã‚      Commencement speeches are customarily routine, pedantic, platitude filled, mildly inspiring lectures.   This description, however, was never applied to Ralph Waldo Emerson's oration, "The American Scholar," delivered to the Phi Beta Kappa Society at Harvard in 1837.   Oliver Wendell Holmes called this speech America's "Intellectual Declaration of Independence."   In addition to being a call for literary independence from Europe and past traditions, the speech was a blueprint for how humans should live their lives.   Emerson believed that the way to reunite with the Over-Soul was to become "The American Scholar."   He would do this by observing nature, by studying the past through books, and by taking action.   To become a scholar, humans also needed to develop self trust, espouse freedom and bravery, and value the individual over the masses.  Ã‚  Ã‚   Because this speech is so pregnant with discussion topics, an intrinsic part of the blueprint   may not catch the reader's attention or receive the analysis it deserves.   It delivers a message that contemporary humans still need to receive.   The startling, heretical admonition not to worship or make false idols of books and other objects of art, given in Emerson's "The American Scholar," demonstrates his belief in the vital necessity for self-reliance and active, creative reading and writing.   When he exhorts us to live as a scholar, as "Man Thinking," rather than "a mere thinker, or, still worse, the parrot of other men's thinking" (1530), he is cautioning us against the false idolatry of book or Bible worship.  Ã‚   When Emerson introduces the second great influence on the spirit of the scholar, he at first praises books.   He expounds on "the mind of the Past,--in whatever form, whether of literature, of art, of institutions, that mind is inscribed.   Books are the best type of the influence of the past" (1532).   Emerson is saying that books are the best vehicle available to the scholar for studying the ideas and accomplishments of past men and ages.   But after affirming that "the theory of books is noble" (1532) and presenting an idealized way of reading and reusing books from past ages by which "business" and "dead facts" come out as "poetry" and "quick thought" when read and rewritten in a new age, Emerson   begins to show doubts that reuse is possible and states that "Each age, it is found, must   write its own books; or rather each generation for the next succeeding.

Eskimo Pie Corporation :: Business Management Essays

Eskimo Pie Corporation Introduction   Ã‚  Ã‚  Ã‚  Ã‚  Reynolds Metals is the majority owner of the ice scream company Eskimo Pie Corporation and has decided to sell this company. Nestle Foods provided the highest offer of $61 Million. Due to delays of the Nestlà ©Ã¢â‚¬â„¢s purchase, Reynolds Metals has take into consideration the IPO proposal of David Clark, president of Eskimo Pie Corporation, rather than selling the company to Nestle Foods (Case Study, 2001).   Ã‚  Ã‚  Ã‚  Ã‚  This analysis will identify the current value of the company at a stand-alone value and explain why Nestle Food would want to buy this company and the synergies involved for their reasoning. We will also discuss who will benefit if Reynolds Metals were to sell to Nestle or were to create an IPO. Finally we will provide a recommendation for Reynolds Metals that will be most beneficial to the company financial needs.   Ã‚  Ã‚  Ã‚  Ã‚   Stand-Alone Value   Ã‚  Ã‚  Ã‚  Ã‚  There are many valuation methods that could be used to evaluate this company. Finding a method that valuates the stand-alone value is difficult. The stand-alone value should be dependent upon the firm’s own assets and projected future income. We decided to evaluate this company based upon two methods: The Discounted Cash Flow Method and the Comparable Companies Method. Discounted Cash Flow Method takes the forecast free cash flows during forecasted horizon. Then we estimate the cost of capital (weighted average cost of capital) and estimate continuing value (value after forecast horizon). The future value is discounted to the present value. We than add back cash ($13 Million) and non-current assets and deduct total debt. With the information provided several assumptions had to be made to obtain reasonable values (life period of 30-years, Capital expenditures not to exceed $1 million dollars, depreciation to stay constant at $1.15 Million and a discounted rate of 10%). Based on our analysis, the company has a stand-alone value of $51 Million at the end of fiscal year end 1990 with a net present value of cash flows of $33 million that does not include the cash and non-current assets a cash of and non-current assets. The greatest risk using Discounted Cash Flow Method is all the assumptions that were made. Without knowing and having complete information this method could report underestimated or overstatement figures. The second method we used to analyze the firm’s value was the Comparable Companies Method. We used the historical figures as of 1990 and Goldmans Sach’s Projections. With an average of 22.
