Gangs Assignment Example | Topics and Well Written Essays - 1000 words

Gangs - Assignment Example Membership to a gang is based upon many criteria, the most important being, socio-economic status, religion, race and culture. Gangs tend to cluster in high-crime, socially disadvantaged neighborhoods (Thornberry et al., 2003) In the sub-urban and rural areas there has been a spurt in gang membership. Gangs began to take root as many immigrants could not cope up with the culture of their adopted homeland and thereby could not assimilate themselves within the new society. These immigrants formed gangs to forge an identity for themselves and took up the role of alternative family providing support to the members. Such gangs also provided its male and female members protection. One of the very distinctive characteristics of gang members are that most of them come from the male minority groups such as Hispanic, African and Asian countries. Other distinctive characteristics are that such members come from poverty stricken areas, those who depend on welfare or those coming from single pare nt backgrounds. Qs. 2. Specific groups of youth and gangs Gang memberships are not a product of several specific risk factors, but the result of the accumulation of many varied kinds of risk factors (Krohn and Thornberry, 2008). One of the specific groups is the youth that are delinquent, are most likely to join gangs. Various environmental and personal factors lead to the joining of gangs. Initially delinquent youth join â€Å"starter gangs† and at a later point in time they graduate to joining serious gangs. Youth experiencing racism, find themselves being denied of resources and privileges. The absence of purchasing power and inability to fulfill basic needs leads to feelings of hopelessness and diminished self worth. Adolescents belonging to this category often form their own establishments. Exposure to anti-social influences and poor performance in school increases the risk of a person joining a gang. Socially maladjusted youths tend to join gangs. Qs. 3 Membership in re lation to age Most of the gang members are very young children between the ages of 10 to 18 years. They are at an impressionable age and thus peer pressure makes them gravitate towards gang membership. Gender is not an issue in relation to age. Both male and female gang members fell mostly within this age group and were expected to carry out their activities as required. Every gang has two or three leaders who head the gang and give out orders to assault, harass or steal from people. However, in Chinese gangs the ages range between 13 to 37 years. (New York City Police Department, 1983) Though some of the youth join voluntarily, others are forced by threatening and other crude methods. Qs. 4 Benefits and dangers of Gang membership Gangs provide psychological support to youth which most of the members do not get from traditional support system like family, religion and school. They are a closely -knit    cohesive structure which provide the members with a sense of belonging, more e specially in the case of immigrants. Lure of easy money entices many to join drug gangs. Gang members are benefited in more ways than one. For example, they are provided with an apartment and food in addition to ammunition to carry out their nefarious work. However, they face the danger of losing their lives in case an operation fails or when conflicts arise among the members themselves. Most of them do not have freedom to do as they want and they live in fear because they have to

Building Maintenance | Literature Review

Building Maintenance | Literature Review Building defects are common phenomena especially for those old residential apartments. Lack of maintenance management is one of the factors which lead to poor building condition. Despite the authorities in charge of building maintenance, the residents are also a factor contributing to poor maintenance on building. Misusing the facilities, poor management team, insufficiency of fund for maintenance, the use of poor quality material by the maintenance department, improper maintenance strategy often cause maintenance to achieve a result less than expected. Poor maintenance management will reduce the building lifespan and accelerate the deterioration process of building. Besides that, poor maintenance also will effects the condition of the building, it is also a threats to the residents, making the residents feel unsafe, cause inconvenience and bring a lot of trouble to the resident and others. Thus, this research aim is to identify the flaw of building maintenance in residential apartments, give recommendations and provide the suitable of maintenance strategy to improve the quality and conditions of the apartments. The center question in this study is to identify a suitable maintenance strategy to improve the condition of residential apartments. Along the way of research, following question will also be identified. What is the flaw of building maintenance in residential apartments? What is the reason to affect the maintenance cost? 1.3 Aim The aim of this research project is to study the building maintenance strategy in residential apartments. 1.4 Objectives In achieving the aim, four objectives have been outlined. There are: To determine the suitable of maintenance strategy to improve the quality of residential apartments. To compare the type of building maintenance strategy. To review the factor that affect maintenance cost. 1.5 Hypothesis Proper maintenance strategy can reduce the building defects, increase the monetary value of apartment and prolong the lifespan of residential apartment. 1.6 Background of the Study Building maintenance is an important activity to keep the building in good condition. Even though the buildings are seemed like wonderful or in perfect condition, there are a lot of maintenance work needed to be done in order to maintain at such condition. To preserve and prolong the life of building, maintenance is necessary to be carried out. Chudley (1981, p.1) define the maintenance as: maintenance is the act of maintaining. The Committee on Building Maintenance in British defined maintenance as: Building Maintenance is the work undertaken in order to keep, restore or improve every facility, i.e every part of a building, its services and surrounds to a currently acceptable standard, and to sustain the utility and value of the building (Wood, 2009, p.3) In this research project, researcher is tending to identify the flaw of building maintenance in residential apartments and proposed the suitable maintenance strategy. The motivation to carry out this research project is a lot of tenants or residents have neglected the importance of maintenance work. Also, maintenance will affect the built environment, building lifespan, quality, safety and condition of apartments. Proper maintenance strategy plays an important role for a building. The proper maintenance strategy is able to affect the performance of maintenance. Good and poor maintenance also depends on the maintenance strategy using. The poor maintenance also caused by using the improper maintenance strategy. The poor maintenance of the residential apartment will lead to depreciation of property value, affects the condition of the building, result as a threats to the residents, making the residents feel unsafe, caused inconvenience to the residents, building efficiency drop and eventually cause the building to deteriorate rapidly than others. 1.7 Scope of the Study In order to carry out the research project, the researcher specified in residential buildings at Setapak. The nature of the building to be focus in apartment and the building will be reviewed in this research are those which were built between 1990s and early 2000s. The building maintenance of the residential apartments is to be reveal through this research project. This research focuses on the maintenance strategy of the residential apartment thus understand on the building maintenance strategies and knowledge on flaw of building maintenance are important in this case. The key words like building maintenance strategy and residential apartments will be defined at first so that the person who reads can easily understand point of the research project or dissertation. To carry out the research, it is necessary to identify flaw of building maintenance of residential apartments and proposed the suitable or proper maintenance strategy to rectify the flaw of building maintenance or improve the quality of the buildings. In addition, in this dissertation identifies the factors that affect the maintenance cost. 1.8 Research Methodology 1.8.1 Literature review To carry out a research, literature review is the most important of the research.

To get back the progress that I was planning, I was tried to confirm the tile on Week 4. After that, there is also late to done the work in Chapter One. Within that delay period, I have a presentation and a lot of assignment need to submit. Also, I was having twice time amendment on Chapter One. During Week 9, I was realized that was very late to start the work in Chapter Two. To resolve this problem, I was try to spending more time to do the research and I was try to finished the introduction, definition and importance of building maintenance and factor affect the building maintenance cost. During Week 9 to Week 12, I was try my best to match back the planned schedule and I was get help who is my supervisor in doing the work in Chapter 2. He is giving a lot recommendation to give me a direction to done the proposal and final draft. Finally, I was done my work on Week 12 and I was submitting my final draft on Week 13. Chapter 2.0 Literature review 2.1 Introduction This chapter reviews the types of building maintenance strategy. The definition and the importance of maintenance also will be identified in this chapter. Besides that, this chapter will identify the factor affecting the building maintenance cost and maintenance management decision diagram. 2.2 Definition of Building Maintenance The maintenance term was comes from the French verb maintenir, which means to hold, retain, prolong or preserve the building or structure to an acceptable standard. Chudley (1981, p.1) defines the maintenance is the act of maintaining, many people are misunderstanding the maintenance is equal with repair. In the act of maintaining repairs or replacement may well be necessary but the main objectives of all maintenance procedures is to prevent as far as practicable the need to repair or replace the structure, furnishings, services, equipment or fittings which collectively make up the total environment of any building (Chudley, 1981, p.1). According to BS 3811: 1964 defines maintenance as a combination of any actions carried out to retain an item in, or restore it, to an acceptable condition (Lee, 1981, p.9). Wood (2009, p.4) defines maintenance as keeping an item at a certain level or of restoring it that position of acceptability, although it does not identify who it is that determines the acceptability condition. Besides that, the Building Maintenance Committee in British recommended the following definition: Work undertaken in order to keep, restore or improve every facility, i.e every part of a building, its services and surrounds, to a currently accepted standard and to sustain the utility and value of the facility (Lee, 1981, p.10). In conclusion, the main objectives of building maintenance is to keep the building in perfect condition and ensure that the condition of the buildings meets all statutory requirements by regularly checking or repairing it when failure occurs so that the building can be continued perform in term of acceptable standard. 2.3 The importance of Building Maintenance Most people are unlikely to carry out maintenance work and they have neglected the importance of maintenance work. There are many good reasons for carry out the maintenance work. For example, maintenance can be preserving our building, prolong the buildings life, reducing the deterioration process of the building, provide a safe environment and maintaining buildings appearance. In the economic sense, maintenance can reduce the major repair projects. Under some circumstances, repairs works can be costly than maintenance work in terms of finances. Thus, it is better to carry out the maintenance work than extending the period of repairs work. For an example, the routine cleaning of the gutter and drains is cheaper and less convenient than having to cope with a serious outbreak of dry rot in timber roof trusses which is neglect for many years. The appropriate routine management and maintenance will minimize the need for larger repairs or it is the most economical way of sustaining an ass et (Beehive, 2010). Besides that, maintenance will also ensure the safety of the building or to person (Jeff, 2008). For instance, maintenance of building fire safety installations. Fire safety installations must be capable performing in standard level to ensure the safety of the building and building users or occupants. Fire safety installations are including fire extinguisher, fire doors, fire hydrants, fire hose reels, emergency lighting and smoke detectors (Queensland Government, n.d). In addition, maintenance also can provide opportunities for employment. Some of the maintenance works are required repair specialist or maintenance professionals to carry out the maintenance or repair works. For example, cleaning high-level gutters may require specially trained personnel or equipment to carry out the work or some of the maintenance or repair work need a lot of repair specialist to carry out the work therefore it provide a opportunities to earn a living (Beehive, 2010). 2.4 The factors that affecting building maintenance cost This research project is to identify the factors that affecting building maintenance cost because the issue of continuous increasing in building maintenance cost is often discussed. In order to solve the problem of increasing in building maintenance cost, building management team should adapt some strategies by reduce or minimizing the number of maintenance activities (Azlan Shah Ali, 2010). Besides that, building maintenance costs increase and decrease will be affected due to the various factors. For examples, designer is fails to comply with the specifications and standard also is a factors that influence the building maintenance cost. (Jalal A. Al-Khatam, 2003) 2.4.1 Design The complexity of the building design will increase the difficulty in maintenance work. Regular cleaning and minor repair work can be carried out easily to avoid major replacement of building component. For example, some of the maintenance requires some tools to be performed. If the designer fails to allow enough space for the tools to execute maintenance work, it will cause minor problem become major problem (Jalal A. Al-Khatam, 2003). The building design also including the building height, area and size. The high rise building is need the additional costs for the equipment and tools used to carry out the maintenance works. For instance, when carry out the maintenance works at high rise buildings such as window cleaning, painting work, repairs work and other external works is need scaffolding (Azlan Shah Ali, 2010). Besides that, some of the building defects are caused by improper structural design such as designer is neglected the spacing for contraction and expansion which movement will cause joint of the wall cracking (Jalal A. Al-Khatam, 2003). 2.4.2 Poor Quality Control Quality control program is essential and important during the maintenance and construction stages. That program is used to control, check and test of activities due to the contract requirement and construction procedures. An effective quality control program will reduce the occurrence of building defects therefore maintenance work will be reduce accordingly. During the maintenance stages, the quality control program is essential to ensure that which component is required to maintain or might not need to maintain (Jalal A. Al-Khatam, 2003). 2.4.3 Lack knowledge of maintenance strategy Improper maintenance strategy is caused by the designer or maintenance management team lack in knowledge of maintenance strategy. Improper using maintenance strategy might not be increase the cost of the particular work but it might be affected on the long-term durability of the building and the cost of maintenance (Jalal A. Al-Khatam, 2003). 2.4.4 Unfamiliarity with local and site condition The designer should know the building location, type of plants, environment condition and insects existing around of the building. For example, if the designers realized that surround of the building have many plants and those plants might have termite or white-ants, it can be provide a suitable maintenance strategy to avoid termite attack. In addition, designer also should be familiar with buildings site condition such as soil condition. For example, poor soil condition might affect the building shrinking and causes the structural elements start cracking (Jalal A. Al-Khatam, 2003). 2.4.5 Improper diagnosis The maintenance management team is failure to identify the main and true causes of the defect and it will affect the decision on decide the maintenance strategy. Besides that, improper diagnosis will affect the maintenance cost. This is because improper diagnosis will worsen the condition of the building therefore it is require a lot of maintenance or repair works to repair it (Jalal A. Al-Khatam, 2003). 2.4.6 Life Cycle Cost (LCC) Life cycle cost (LCC) is the total relevant costs over the life of a system including cost of operation, maintenance, acquisition, disposal and modification for the purpose of making decision (Shear, 1993). LCC takes into account firstly and other costs (total cost of operation and maintenance of a system) over a buildings life. During the buildings life period, it helps in the determination of how the owners money distributed. Moreover, it was to determine of meeting a need of space with the most economic way. Besides that, it was also assisting in developing the most economic plan shape, structural form and internal layout. The greater saving and lowering the committed cost if LCC is applied earlier. LCC is used to identify which have the lowest total cost of design feature, components and finishing. And, it also identifies high cost areas and evaluates changes that will reduce these costs (Jalal A. Al-Khatam, 2003). 2.4.7 Labour Unskilled labours such as foreign labour will failure to carry out the maintenance work and it is also will increasing the maintenance cost if they have not performing well in maintenance work. It is because they are lack in experience, knowledge and skills to perform well of the maintenance work. Therefore, employ a skilled labour is better than employ unskilled labour. Skilled labour will help to minimizing maintenance cost and improve the quality of work (Jalal A. Al-Khatam, 2003). 2.4.8 Material selection Material selection in the early design stage also is the one of the factors will be influence the maintenance cost. Once the selection of materials is failure or select wrong materials it is required high maintenance cost to repair or replace the existing building components (Azlan Shah Ali, 2010). The selection of poor or bad quality of materials will cause failure of the materials and deterioration occurred in the building components, which will require replacement or more maintenance tasks in the future. To minimize future expenses during maintenance stage, selection of materials should be according to the performance specification requirements of the building (Jalal A. Al-Khatam, 2003). 2.4.9 Misusing materials The misconception of using cheap materials will minimize or reduce the maintenance cost. Those cheap and bad quality materials will cause building deterioration, which will require more maintenance or repairs work to be carry out. It will be more costly to carry out the repair, replacement and maintenance work (Jalal A. Al-Khatam, 2003). 2.4.10 Fluctuation of Material Prices The most common of factors that affecting the maintenance cost is fluctuation of material prices such as cement, steel bar and etc. it might be increasing the material prices and also decreasing the material prices but usually is increasing (Jalal A. Al-Khatam, 2003). 2.4.11 Climate change Some of the building material will have chemical reaction when the climate was change. For example, acid rain wills accelerate the deterioration process of some building materials. Thus, there are some maintenance or remedial action need to be carry out (Jalal A. Al-Khatam, 2003). 2.4.12 Unqualified Maintenance Contractor To ensure the maintenance work can be performing effectively, the well-experiences maintenance contractors are very important. A good maintenance contractor should be good in analyzing the maintenance cost and analyze which maintenance strategy is most economical way to carry out the maintenance work or which is the most suitable maintenance strategy can be using (Jalal A. Al-Khatam, 2003).. Besides that, those of the unqualified maintenance contractor or operator are lack of training which could cause to poor operating and maintenance practices (Azlan Shah Ali, 2010). 2.4.13 Age of the building According to Skinner (1982), Slater (1982) and ONeill (1974), the age of the building or property also could be influencing the maintenance cost. When the age of a building increase, the maintenance cost also will increase accordingly. Some of the maintenance works such as replacement of new roof tiles, painting work, and other works are required to carry out because these maintenance works is to ensure the sustainability of building while the building age is increasing (Azlan Shah Ali, 2010). Besides that, the building components have their expected life, if the building components life is over than the expected life, it is better to demolish it or replace it. This is because the maintenance cost might be higher than the cost spending on demolished or replacement (Jalal A. Al-Khatam, 2003).. 2.4.14 Poor management A good maintenance management can be an effective tool or equipment for achieving a high standard of maintenance work and it can reduce the maintenance works and costs. According to Horner et al. (1997), the maintenance management is required to reduce or minimize the repair works on building defect (Azlan-Shah Ali, 2010). Without maintenance management, it will lead to failure maintenance work, time consuming and cumbersome. Therefore, maintenance management is requiring formulating long term strategic plan to meet those needs. 2.4.15 Poor financial management The building owners are require to preparing the annual budgets which budgets is enough financial support for maintenance work. Without financial support for maintenance work required, maintenance works require to carry out will not be perform properly and building will not maintained properly (Jalal A. Al-Khatam, 2003). 2.4.16 User neglected importance of maintenance work Building users are often misunderstanding that there is not their responsibility to keeping the building in good condition and facility therefore they are taking no action or neglected the maintenance work. As time passes, it will lead to the buildings start to deteriorate. Therefore, they require additional maintenance cost to carry out large repair or maintenance work to cope the deterioration of the building. Therefore, it is better that they are intention to carry out the maintenance work before the building is deteriorated (Jalal A. Al-Khatam, 2003). 2.4.17 Misuse of building after construction is complete Some of building users or owners is misusing the buildings and its components in proper way after the building construction is completed. There are causing the building components are needs to repair and it is also would be costly for those repairs work (Jalal, 2003). In order to minimized this problem, the introducing of property operating manuals and regulation, and educating occupants and users are need to be carry out (Azlan-Shah Ali, 2010) 2.4.18 Behavior and attitude of users The bad attitudes of building users are often misusing the facility and services of the building and vandalism by building user will cause to damage and defects on building components. It would be costly to repair for those damages (Jalal A. Al-Khatam, 2003). 2.4.19 Improper Maintenance Strategy Improper maintenance strategy also will be affected the cost of maintenance. For example, a building elements are require to using the preventive maintenance strategy but they are using corrective maintenance strategy therefore it is more costly to carry out the maintenance (Jalal A. Al-Khatam, 2003). 2.5 The types of Buildings Maintenance Strategies According to Chudley (1980, p.110), defines maintenance as any work undertaken in order to keep or restore every part of a building to an acceptable standard. The types of maintenance activities which are require achieving this objective. It can be categorized as planned and unplanned maintenance. Those of the maintenance strategies are provide options to decide which maintenance strategy will be decide to use, it should be make sure that those alternative decisions are available to management in maintaining a building. Besides that, it is also need to depend on the failure elements condition then decide a maintenance strategy to repair or replace it. During making decision to select maintenance strategy, it must be consider which maintenance strategy is more efficiency (Chudley, 1981). Figure 0 Types of Maintenance Source: (Abdul-Mohsen Al- Hammad, n.d) 2.5.1 Planned Maintenance is defined the planned maintenance is the maintenance work have been planned, organized and execute with forethought, control and the use of records to a predetermined plan (Abdul-Mohsen Al- Hammad, n.d). Besides that, planned maintenance can be used to overcome the disadvantages of corrective maintenance and emergency maintenance. It is commonly referred to the schedule system which is require consider time, cost and quality. Planned maintenance is including preventive maintenance. 2.5.1.1 Preventive Maintenance (PM) In this maintenance strategy, the building components, elements, facilities and services are subjected to a regular schedule of maintenance tasks, such as cleaning, inspections, adjustments, inspections, and others. The maintenance tasks are carried out at fixed intervals to reduce building deteriorated or to ensure the building is in good condition (RDH Building Enginerring Ltd, n.d). Besides that, the disadvantages of corrective maintenance can be overcome by preventive maintenance. Preventive maintenance also will reduce the probability of occurrence of failure or defects and avoiding sudden failure. This maintenance strategy is referred to as time-based maintenance, planned maintenance or cyclic maintenance. Preventive maintenance tasks are performed in accordance with a predetermined plan at regular, fixed intervals, which may be based for example on operating time (IMSS Security Services, 2011). Preventive maintenance has various advantages over the corrective maintenance. The preventive maintenance tasks are providing several advantages, those are shown as below (Au Wai Hoe, 2008): The equipment will perform more efficiently. Preserve and prolong the life of the building. Reduce and avoid the occurrence of failure. Save potential energy and prevent energy will go to waste. The preventive maintenance cost is more economical than the corrective maintenance cost. The following are the disadvantages of preventive maintenance. Unnecessary task will be carried out even thought the building components are in good condition. The elements which are required remained in a safe and acceptable condition for long time; it will be carried out a large amount of unnecessary tasks. Very demanding in terms of spare parts and labour. Although the preventive maintenance work is carried out, failures are still likely to occur because it was human error during the implementation of the maintenance works. In addition, there are some of the advantages of preventive over corrective maintenance as shown as below: It will not make the building users inconvenient while execute maintenance work because maintenance can be planned ahead and performed when it is convenient to the users. Avoiding the cost of consequential damage can be reduced the maintenance cost. It can be minimized the downtime which is the time that an element of the building or whole of the building is out of services, so that the habitability of the building can be increased. Improved health and safety of the building users. 2.5.1.1.1 Condition-based maintenance This maintenance strategy work is performing in response to an acceptable deterioration in a unit as indicated by a change monitored parameter of the units condition or performance. The reason for carrying out the maintenance work is the condition of building elements has been change or deterioration, and the optimal time to execute maintenance works is determined by monitoring the actual state of the system, its performance or other condition parameters. Its concept recognizes that the main reason for carrying out maintenance is due to change in condition or performance of an item. Before a major failure occurs, to identify the element or equipments requires maintenance which is condition-based maintenance tasks. This maintenance tasks is planned by good monitoring to the buildings elements and service equipment. To make this strategy perform or works effectively, it is need to monitoring the condition of the building components or item. Those monitoring works is to identify whether there is any evidence of change from a normal to abnormal condition. This maintenance can be carried out by selecting the factor which can be best described the item and monitoring changes using suitable condition monitoring tools. Condition measurement can be change from a simple inspection or visual check to more advanced assessment by using variety of condition monitoring tools and techniques (IMSS Security Services, 2011). 2.5.2 Unplanned maintenance Unplanned maintenance works is executed without predetermined planning. In this strategy, the maintenance work is carried out after a failure has occurred (Abdul-Mohsen Al-Hammad n.d). The repair works of the unplanned maintenance is the restoration of an item to an acceptable state or level through replacing, renewing and mending damaged parts. Unplanned maintenance cost is more costly than planned maintenance cost. Besides that, unplanned maintenance includes corrective and emergency maintenance. 2.5.2.1 Corrective maintenance Corrective maintenance is the simplest types of maintenance strategy, where a building element is used until it cannot perform or breaks down. It covers all activities, including replacement, repair and renew of a building element that has failed to a point at which it cannot perform its required function or cannot carry out the services. This maintenance strategy is carried out the work after a failure or defects has occurred and intended to restore an item to an acceptable state to perform its required func

American Eel Gatlin Edge WFB- 440, Feb 11, 2014, Rodriguez The American Eel (Anguilla rostrata) is South Carolinas only catadromous species. Unlike anadromous species that migrate into the rivers of South Carolina from the ocean to spawn and then return to sea, the American Eel does just the opposite. It is naturally found in rivers and streams along the Atlantic coast and migrates to the open ocean to spawn. Little work has been done on this species which leaves much to be discovered about this unique specimen. Generally females are larger in size and can grow up to two times the size of males and also grow at a faster rate (Geographic effects on American eel 323). The American Eel has become a species of interest on the east coast of America due to its new found economic importance. Due to the decline of the European Eel (Anguilla Anguilla) oversea markets have begun to take interest in buying eels from the United States (Georgia Tidal Creek 821). Studies have shown that the average home range for these eels is 1.04 hectares (Georgia Tidal Creek 823). Most age classes of eels wi...

Acid rain is the term for pollution caused †¦ f one oxygen atom and two hydrogen atoms. The oxygen atom also called the â€Å"apex of the water molecule† bears a slight electronegative charge while hydrogen possesses a more positive one (Kirk 225). Because of the opposite charges attract, the water molecules are drawn together. When an oxygen atom is linked to a molecule's hydrogen atom, a bond called a hydrogen bond is formed (Kirk 256).

Without water, life as we know it would not have been possible. It's important to understand and examine the water molecule in order to ascertain how it brought about Ear th's thriving ecosystem and how important it is for us today. Water is a strong solvent, it's a very unique molecule that can breaks and reforms constantly. Each water molecule consists acid What is acid rain? Acid rain is the term for pollution caused †¦ f one oxygen atom and two hydrogen atoms. The oxygen atom also called the â€Å"apex of the water molecule† bears a slight electronegative charge while hydrogen possesses a more positive one (Kirk 225). Because of the opposite charges attract, the water molecules are drawn together. When an oxygen atom is linked to a molecule's hydrogen atom, a bond called a hydrogen bond is formed (Kirk 256).

Main Purpose of Education

Main purpose of education Nowadays,Hong Kong education system has an controversial issue which is about the teachers train their students in order to ensure they obtain the highest grade in public examination. As a result ,they do not know how to apply the knowledge they learned into the workplace. Teachers only teach the knowledge and students recites the information from the textbook,thus many secondary school graduates are lack of the ability to present their opinion and idea in a precise and organized way..The current education system ignores the main purpose of education which is to train the students’ critical thinking in the lesson. Practicing the critical thinking is definitely essential for the students because they have to contact with the hustle business environment after they graduate from the college. If they can elaborate their point of views in current affairs clearly before they graduate, they could compete with other candidates and have the higher opportunity to be hired by employer.The world is changing and going forward gradually, as Charles Darwin have said ‘Survival of the fittest’. There is a great deal of workers who has high education level in society, the employer tend to employ the people who can criticize and analyze social topic with valid reasons since well critical thinker can communicate effectively and easier to find solution of complicated problems. Provided that the students equip with critical thinking, they can be an independent and lifelong learners.Moreover , being a competitive worker should apply the critical thinking in the daily life ,instead of reciting the theory from the textbook. Even if students can comprehend the textbook’s knowledge ,it still have colossal difference between the theory and real condition. For instance, if you learned the marketing skill through the textbook, it is impossible to duplicate the whole theory in the varied business environment since there are numerous uncert ain and unpredictable factors such as adjustment of government policy to affect the decision making.Therefore, it is crucial for the students to learn how to criticize the issue since the secondary school education. After we understand the significance of critical thinking, there are several ways to exercise the students to equip with it by the parents and teachers. Firstly, teacher can change the teaching approach so as to make the students can ponder the same issue in various angles. They should adopt multidisciplinary education method instead of spoon-fed education method.They can inspire and motivate the students to think more about social issue and topic, whereas the students can express their notion to teacher and student. For example, when they learn the social condition in China, teacher can teach them the current social issue such as the problem of rural and urban disparity rather than using the outdated examples in the reference book. Having more opportunity to discuss the issue with classmates is an effective way to cultivate students’ critical thinking in the class.Secondly ,the parents can instruct their children through the social issue as many adolescents love to face the virtual environment and they overlook the social topic . When they receive the news from the media ,they will not analyze and assess the topic immediately because their parents force them to attend the tutorial and they only get the skill to answer the questions, not the ability of critical thinking.Being attentive to current affairs will enhance the competence of critical thinking,hence the parents can encourage their children to read more editorial in newspaper since the students can develop their own reflection on some issue after they comprehend other’s point of view . Ultimately, getting the highest grade does not equal to obtain the better occupation. The aim of education is not only to let the students learn the knowledge and apply it to the real situation. More importantly, it should train students to be well critical thinker for the sake of working in the society.
