History of Municipal Solid Waste (MSW) - Research Paper Example Introduction Open dumps and landfills have been used over the years as a place for waste disposal. Open dumps were used back in 1950’s and 1960’s. However, they unhygienic and had a lot of negative impact to the environment. Therefore, most of them were illegally created. Later, in 1970’s early landfills were created to cover the dump sites so as to reduce it impact to the environment. However, this early landfills lack proper equipments and designs that enabled the waste to be disposed off properly. This brought more research and modern landfills were created. These landfills are well deigned, planned and monitored thus improving waste disposal method. Further, these landfills also act as sources of energy and revenue to municipalities. 1. Open dumps are abandoned piles of garbage, household appliances, bags of yard waste, used tires and demolition debris such as shingles, lumber, asbestos and pipes in large quantities. There are commonly found in backyard, fore sts, abandoned swimming pools and buildings. Generally, open dumps are created when making building foundations (Binder et al, 2007). Open dumps are usually not permitted thus illegal. Often, if open dumps are allowed they tend to grow very large. 1a There are many problems associated with open dumps as it possesses safety, health and environmental threats. These environmental threats include; air pollution: open dumps has garbage’s of from different source which react to produce toxic gases. These toxic gases are inhaled by humans and animals around the area thereby causing respiratory diseases. Open dumps also cause water contamination in rivers, streams, lakes and even ground water. This leads to drinking water contamination thus resulting to water scarcity as water is a scare resource. Furthermore, open dumps cause a lot of damage to the natural ecosystem that is the plants and wildlife habitats. They cause soil contamination, which does not work well with the plants and animals. Evidently, local communities near open dumps have high prevalence of diseases such as malaria because open dumps carry disease carrying mosquitoes, rodents and flies. Moreover, open dumps cause a loss of aesthetic value of a location. Due to the many types of garbage in the open dump it makes the area unattractive, smelly and unbearable environment. Lastly, open dumps cause fire and explosion which in turn cause severe damage to the environment. These also decrease the quality of life of residents and local community living around it. 2 Early landfills were constructed without much technology and designing put to it. They were constructed in the 1970’s, to control the problem of odors as a result of sanitary landfills. They mainly entailed installing cover system in formal dumpsites to deal with the problem of windblown refuse and often fires caused by the open dump sites. These early 1970’s landfills were constructed without leachate and liners collection sys tems (Reno, 2008). Lack of leachate collection system becomes one of the major problems associated with these landfills. 3 Leachate is the liquid that comes from dew and rain, and natural moisture penetrates through waste. It moves through the waste dissolving salts, picking up organic components and leaching heavy metals. Furthermore, landfill leachate has an organic strength greater than 20 to 100 times that of raw sewage. Consequently, this makes it a potentially potent polluter of groundwater and soil.

Marriage and Dating - Essay Example Was it a consequence of parents not being concerned in choosing the one their children should date or marry Or was it for the reason that parents are so strained in choosing the partner/suitor for their child There are numerous cultures where the parents are implicated in choosing whom their children should rendezvous or who to marry. These are widespread scenarios as to traditionalists. There are some matters involved as to the reason of such conduct of parents such as cultural variety or religious wisdom but also occurrence to broken homes and just pure concern to their children. The optimistic side as to parents deciding the one you date or the one you should wed are the for the subsequent motives: your parents only fancy the finest for you; they want somebody that is maybe for them is more fine looking or presentable, reputable or for other basis; they would want a spouse that would best suite you as to ethnicity, monetary status or even political status; the affluence of the family will not be shared to of those they consider that are lesser than yours but ought to be equivalent or superior than you have is a must; or they want to follow cultural norms; or merely they believe that the person they would like would mesh well with you than the one you opt. The downside of this is how about what you would like Almost certainly being with the person they chose would be agony on your part because of indifferences as to fondness, cultures, compatibility issues and the like which may lead to unproductiveness of the connection or even break up, heart ache and eventually separation. Family sociologists have shaped a variety of theories to make clear cultural and tribal disparity in marriage. Financial resources, partner-selection course, and culture are the center notion for the most widespread of these enlightenments. Both premise and experiential scrutiny suggest that larger economic possessions allow marriage and can amplify the motivations for marriage, particularly for men (Becker, 1991; Oppenheimer, Kalmijn, and Lim, 1997; Landale and Tolnay, 1991). When we sight the whole range of history and at hand human societies matrimony can be portrayed as a ethnically accepted relationships or a amalgamation of one man and one woman that is monogamy, of one man and two or more woman which is polyandry, there is cultural support of sexual contact amid the wedded partners of the conflicting and, generally, the anticipation that children will be bear of the affiliation (International Encyclopedia of the Social Sciences, 1977). To get the endorsement of the society it is essential that the unification be formed and documented in agreement with the understood mores and taboos, as in customary societies, or in agreement with standard laws, as in more urbane societies (Westermark, 1977). The tradition of marriage differs in a variety of parts of the globe and every civilization produces a marriage prototype suitable to itself (Ludlow, 1965). For Asian cultures it is ordinary to them that the parents would concur to each other that their brood should end up collectively. Maybe for the grounds of the following: keeping their affluence within the family, not allowing other backgrounds to mix with their culture, their child's hand for matrimony for trade

Evaluating Eligibility Rules Essay Example for Free

Evaluating Eligibility Rules Essay In determining which eligibility rules can be associated with the Lakeland Police Department, it the objectives of such institution must be looked into before going through the details in which such rules apply. The institution provides public and security measures to the community it holds. They promote the welfare of the people around them under the parameters mandated by the law in the creation of such institution. With this, the eligibility rules that the agency uses revolves around the (1) eligibility by administrative rule and regulation, (2) eligibility by administrative discretion and (3) eligibility by judicial decision. To understand whether the eligibility rules advocated by the agency promotes a stigmatization, trade-offs or off-target benefits, each rule must be looked into in accordance to the application of such within the Lakeland Police Department. The eligibility by administrative rule and regulations creates â€Å"an advantage to client beneficiaries because it gives social workers and other human service staff members a means by which to administer the benefit or service program evenhandedly and reliably, so that people similarly situated are given similar benefits. (Chambers and Wedal, 2005, p. 112) This rule can be seen to create trade-offs within the system of Lakeland Police Department. Trade-offs is evident because of the situational circumstances in which this rule can be applied to citizens within the district. There are implications of such applications in the way the police department addresses the people. â€Å"On the other hand, administrative rules restrict the freedom of staff members to use their discretion that is to judge need for the benefit or service in individual circumstances. (Chambers and Wedal, 2005, p. 112) The next thing is the eligibility by administrative discretion. This discretion sees to it that all particular concerns within a system need to be addressed by the agency. â€Å"All general organizational policies and administrative rules must be interpreted and applied to individual situations, so it is important to understand that such interpretation and applications necessarily involve significant personal judgment on the part of the staff member. † (Chambers and Wedal, 2005, p. 14) With this, it can be seen that there is a stigmatization of benefits among members of the community handled by the Lakeland Police Department. Their capability to address situations of its citizens particularly concerning their welfare in accordance to the law and mandates of the city can clearly be seen. This creates benefits among locals on the assurance that their welfare is protected by the agency. Lastly, is the eligibility of judicial decision. This rule can also be seen as applicable to the Lakeland Police Department. After a program has been in operation for a period of time, it is very likely that a contention will arise about whether the enabling legislation or whether an administrative rule or discretionary judgment was faithful to the spirit and intention of the law under which the program or policy was established. † (Chambers and Wedal, 2005, p. 115) It can be seen that this categorization creates an important part of the Lakeland Police Academy. This creates a stigmatization of benefits among local citizenry. It may be true that the agency can exercise administrative discretion, however issues may arise between the proper execution and application of such initiative among members of the community. This rule seeks to create a check-and-balance among the members of the police force. It is true that the objectives are in-line with the rules and mandates of the law, however, the actual practice remains to be on the part of local enforcers and policeman. This creates a subjective interpretation of actions by enforcers that more often than not leads to judicial contention. Appeals to the judiciary for clarification of the law are routine and in the end they can become as important as the legislation or administrative rules themselves. † (Chambers and Wedal, 2005, p. 115) To determine whether there are weak rules in the system of Lakeland Police Department, the three eligibility rules again must be looked into. On the eligibility by administrative rule and regulation, there exists a problematic issue on how to effectively distinguish what are the different parameters for such actions. The agency may have difficulty in promoting the necessary measures present if such issue persists. â€Å"Therefore, it is important to know whether a certain entitlement rule originates with judicial decisions, administrative rule, or individual staff discretion, for on that fact depends the probability of change – staff decisions certainly are changed more easily than are formal rules and statutes. † (Chambers and Wedal, 2005, p. 112) On the other hand, the two other eligibility rules are described to be minimal in problems. This is due to their ability to sink within the system and serve as both a check-and-balance among local authorities under the Lakewood Police Department and an initiative to further create changes that the department needs to address the changing needs of the future. Eligibility rules are characterized to create a foundation for actions by people. In the case of Lakewood Police Department, it seeks to cater the needs of the locals in promoting security and their welfare. In the issue of such eligibility rules being fair, it can be argued that they are indeed fair overall since it is based from the mandate of laws and legislation. The only issue here is the actual application of such rules by people who supposed to be fit for the description. Sometimes, there is a subjective interpretation of how such rules can be applied. This creates the sense of disparity of opinions and practices to both local and enforcers of such rules. On the other hand, tackling the issue of sufficiency, yes, it can be argued that the rules applied during that time are sufficient to address the current need of the locals. However, it may not be the case in the future as new issues and challenges arise within the new system. That is why, changes in the system and rules are needed to further pursue the interests of people. For one, rules are and regulations are meant for the people to ensure their security and welfare within the community.

Effect of Surface Area in an Experiment

Effect of Surface Area in an Experiment Title: The effect of surface area in an experiment. Chosen factor: effects of surface area Chosen experiment: Calcium carbonate and Hydrochloric acid (option 2) Questions: Will increasing the surface area of the calcium carbonate slow down the reaction rate? How do you increase the surface are of Calcium Carbonate? Will increasing the surface are of Calcium Carbonate speed up the reaction rate? Will the smaller surface area Calcium carbonate have a faster reaction rate than the larger surface area Calcium carbonate? Background Information: What is a reaction rate? A reaction rate is the rate in which a chemical reaction occurs. (Britannica.com, 2017) The reaction rate can be increased by increasing the surface area (crushed material). For example, in custard powder factories, there is a high rate of the custard powder exploding, because of the larger surface area. This happens because the finer the substance is crushed, more particles are exposed to the other substance in the experiment (BBC,2014) To increase surface area, the material needs to be crushed into a powder. For less surface area, the material needs to stay in a big clump. Diagram sourced off (BBC, 2014) This diagram shows the reaction rate of a greater surface area (blue) is much faster than the smaller surface area (red). The finer a substance is, generally, the faster the reaction rate will be. The larger surface area can also act as a Catalyst. (chemguide,2013) Collision theory is a theory based off particles of elements colliding together, which creates a chemical reaction. Any collisions without enough energy wont produce a reaction. For a reaction to occur, there must be energy within the atom which will cause them to collide together to create a chemical reaction. (BBC,2014) Calcium Carbonate and Hydrochloric acid: In the experiment the Calcium Carbonate will be crushed, then combined with the hydrochloric acid. Alongside the crushed calcium carbonate will be two other different grades of Calcium Carbonate which will have a lower surface area to each other. The different grades reaction times will be compared to each other in 3 different experiments. Experiment formula: calcium carbonate + hydrochloric acid calcium chloride + carbon dioxide + water CaCoÂÂ ³ + 2HCI CaClÂÂ ² + H2O + COÂÂ ² (Chemguide, 2013) Hypothesis: It is hypothesised that when the surface area is increased, the reaction rate will speed up. When the surface area is decreased the reaction, rate will slow down because, the chemical can only react with the outside of the substance and chew away at it until there is none left, but with an increased surface area there is more atoms to react with compared to a small surface area. The independent variable that will be changed is the surface area of the calcium carbonate (small, medium, large). The dependent variable will be the time of the ration rate in each experiment. The controlled variable will be the amount of calcium carbonate and the amount of hydrochloric acid that is in each experiment. Method: Collect all equipment needed for the experiment. Setup experiment, then add 100ml of Hydrochloric acid to each of the beakers. (when adding Hydrochloric acid to the beakers, ensure eyes are at the same level of the beaker to make an accurate measurement. Add all 3 Different grades of Calcium Carbonate to each one of the beakers (make sure Calcium Carbonate is placed in each beaker with care.) Setup should look like this: Start timer and record results in a table as shown below. Surface area: Time: Large (powder) 1:02mins Medium (medium chips) 10mins+ Small (big chips) 10mins When the reaction completely stopped, all chemicals are tipped into the sink and the sink is washed clean of chemicals. All equipment that has been used is cleaned, and packed into the box. Wet and dry wipe table with disinfectant, ensuring all chemicals have been removed off the surface. Aim: The aim of the experiment was to find out if a larger surface are has a faster reaction time than a smaller surface area. Equipment list: Stopwatches (3) Calcium Carbonate: (large chips, 18g) (Small chips, 18g) (powder, 18g) Hydrochloric acid (270ml) 1M Watch glasses (3) Spatula Measuring cylinder Beakers (3) Gloves Apron Goggles Risk assessment: Possible Risk Prevention Glass breakage Carry all beakers with care. Do not try to cool glass down with cold water otherwise it will smash. Chemical spillage To not run with chemicals, and watch what you are doing with your body parts. Chemical contact with skin or cuts Wash out thoroughly Results: 1st experiment: Surface area: Time: Observations: Clarity: Large 1:02 mins Bubbling reaction, slowly dissolving, sizzling noise, long time to dissolve, white bubbles. Clear Medium 10 mins+ Bubbling reaction, makes liquid cloudy, sizzling noise, reaction is slow, little bubbles, slowed at 8 mins. Cloudy Small 10 mins+ Furious reaction in the first 10 seconds, slowed down at 15 seconds, loud sizzling noise finished just over 1 min. Very cloudy 2nd Experiment: Surface area: Time: Observations: Clarity: Large 1:01 mins Medium 10 mins+ Small 10 mins+ 3rd Experiment: Surface area: Time: Observations: Clarity: Large 1:09 mins Medium 10 mins + Small 10 mins + (Made by Mac Ross on excel) (Made by Mac Ross on excel) Discussion: All results were in seconds difference to each other. All experiments had the exact same reaction happen every time. All research that was taken was accurate. The hypothesis which was stated was It is hypothesised that when the surface area is increased, the reaction rate will speed up. When the surface area is decreased the reaction, rate will slow down because, the chemical can only react with the outside of the substance and chew away at it until there is none left, but with an increased surface area there is more atoms to react with compared to a small surface area. This hypothesis was supported, because the smaller the surface area was, the faster the reaction happened. Surface area is used in many different scenarios in the world to this day. One of these is in carburetted engines. When fuel goes though the carburettor the fuel gets made into a mist, which is far more explosive than just a drop of fuel. The graphs both show that all of the experiments were very similar. The lar ge surface area experiment when significantly quicker than the other 2. With an average of 1:04 minutes for reaction rate it smashed the other 2. The reaction mainly happened in the first 15 seconds and then slowed down a lot, but it was still fizzing. The other 2 experiments were fizzing the whole time with no increase or decrease in speed with fizzing. The Medium surface area experiment had a misty fizz to it but it wasnt anywhere near as aggressive as the large surface area experiment. We stopped the experiment at 10 minutes as it was taking too long for the experiment to end, but there was defiantly a decrease in size. The small surface area experiment was a very slow reaction compared to the large surface are reaction. Its bubbles were big and not aggressive at all. We also had to end this experiment at 10 minutes because it was taking too long. Evaluation: The Experiments went according to plan, and there were no mishaps. Having 3 experiments going at once saved us a lot of time, and having all of the calcium carbonated crushed up and ready to go also saved us lots of time, which worked well. Not being able to complete the whole reaction for the small and medium surface area reactions was something that didnt work. Our group went together like peas and carrots. To make the experiment more accurate I would have used a stronger acid, so that we could get a result for each reaction, a bigger working space so that everything wasnt cluttered, to accurate measuring equipment, so we could improve on the accuracy, and I would have taken better photos to put in the write up so that people can see the layout better. If I was to repeat this experiment again I would use less calcium carbonate and a stronger hydrochloric acid, so that we could get a time for each experiment instead of ending the experiment at 10 minutes. This also would have given us a better understanding of how surface area affects the reaction rate. Conclusion: When the surface area is increased between calcium carbonate and hydrochloric acid, the reaction rate is sped up. The hypothesis was supported by the results in the experiment. The results showed that the research and hypothesis were all accurate, and the results were that the larger is surface area is the fast it will react. The small the surface area was, the slower the reaction was, but the experiment did have some mishaps, which can be easily be tweaked to be the perfect experiment. But the experiment was successful in finding the result we were looking for, not only because of chemical reason but because of how our group worked together as well. Reference list: Bbc.co.uk.

bless me, ultima :: essays research papers

Chapter 3 Summary When Antonio awakes, he ponders the fate of Lupito's soul and those of the men who killed him. His parents quarrel as they always do on Sunday mornings, as Gabriel's vaquero mindset is not favorable to priests. When Marà ­a scolds Antonio for not being properly formal when greeting Ultima, Ultima requests that she back off because the night was hard on all men. Marà ­a protests that he is still a baby. She thinks it is a sin for boys to become men. Many women in town are dressed in mourning because of sons and husbands lost in the war, which has indirectly claimed two more victims. Antonio and Ultima discuss the events of the previous night. She states that she doesn't think Gabriel fired at Lupito, but she warns that no one should presume to decide whom God forgives or not. Before mass, Antonio mingles with the other boys. They horse around and discuss the night's events. Antonio contributes nothing to the subject of Lupito's death. Commentary Having been introduced to an adult moral dilemma, Antonio is obsessed with sin and punishment. Ultima explains that men of the llano, referring to Gabriel and Narciso, will not kill without reason. However, she also tells Antonio that people have to make independent moral decisions based on what they know. However, matters of salvation and damnation are not for human beings to determine. In her own way, Ultima is talking about fate and destiny within the language of Catholicism because those are the terms with which Antonio is trying to make sense of Lupito's death. Moreover, Ultima tries to subtly let Antonio know that the adults he loves and trusts are not infallible. Narciso and Gabriel both tried to save Lupito, but the blind anger and fear of Chà ¡vez and the others prevented them from doing so. Furthermore, Ultima does not tell Antonio what to think but how people like his father and Narciso make moral decisions. Antonio can then apply this understanding to his own decisions. The opinions that Marà ­a and Gabriel have of growing up highlight the major issues of sin and punishment that preoccupy Antonio. His mother associates growing up with learning how to sin, while Gabriel and Ultima view growing up as an inevitable process that is not good or bad in itself. As a boy becomes a man, he uses his life experience and his knowledge to make decisions.

Societys Restraint To Social Reform :: essays research papers

Society's Restraint to Social Reform Of the many chatted words in the social reform vocabulary of Canadians today, the term workfare seems to stimulate much debate and emotion. Along with the notions of self-sufficiency, employability enhancement, and work disincentives, it is the concept of workfare that causes the most tension between it's government and business supporters and it's anti-poverty and social justice critics. In actuality, workfare is a contraction of the concept of "working for welfare" which basically refers to the requirement that recipients perform unpaid work as a condition of receiving social assistance. Recent debates on the subject of welfare are far from unique. They are all simply contemporary attempts to decide if we live in a just society or not. This debate has been a major concern throughout history. Similarly, the provision of financial assistance to the able-bodied working-age poor has always been controversial. On one side are those who articulate the feelings and views of the poor, namely, the Permissive Position, who see them as victims of our society and deserving of community support. The problems of the poor range from personal (abandonment or death of the family income earner) to the social (racial prejudice in the job market) and economic (collapse in the market demand for their often limited skills due to an economic recession or shift in technology). The Permissive View reveals that all participants in society are deserving of the unconditional legal right to social security without any relation to the individual's behaviour. It is believed that any society which can afford to supply the basic needs of life to every individual of that society but does not, can be accused of imposing life-long deprivation or death to those needy individuals. The reason for the needy individual being in that situation, whether they are willing to work, or their actions while receiving support have almost no weight in their ability to acquire this welfare support. This view is presently not withheld in society, for if it was, the stereotype of the 'Typical Welfare Recipient' would be unheard of. On the other side, the Individualists believe that generous aid to the poor is a poisoned chalice that encourages the poor to pursue a life of poverty opposing their own long-term interests as well of those of society in general. Here, high values are placed on personal choice. Each participant in society is a responsible individual who is able to make his own decisions in order to manipulate the progression of his own life. In conjunction with this opinion, if you are given the freedom to make these decisions, then surely you must
