Problem Behavior Syndrome Essay Example for Free
Problem Behavior Syndrome Essay Problem Behavior Syndrome Sandra Schaumleffel Everest University The life course view is that criminality may be best understood as one of many social problems faced by at-risk youth, referred to as problem behavior syndrome (PBS). In this view, crime is one among a group of interrelated antisocial behaviors that cluster together and typically involve family dysfunction, sexual and physical abuse, substance abuse, smoking, precocious sexuality and early pregnancy, educational underachievement, suicide attempts, sensation seeking, and unemployment. People who suffer from one of these conditions typically exhibit many symptoms of the rest. All varieties of criminal behavior, including violence, theft, and drug offences, may be part of a generalized PBS, indicating that all forms of antisocial behavior have similar developmental patterns. (Siegel, p. 228) I knew a girl whom I was best friends with for almost 10 years. During year 6 of our friendship, I moved out of state. We still kept in contact. As the years went by, we slowly stopped talking. When I finally moved back to our hometown, I found out that this friend had turned to drugs, violence, and had a very long criminal record. I wanted nothing to do with that because I was trying to better myself. Unfortunately, she is still running down that wrong path, in and out of jail, on various different types of drugs, and even losing custody of her three children. This friend of mine possesses many of antisocial behaviors. Some would include substance abuse, early pregnancy, educational underachievement, and unemployment. Iââ¬â¢m not sure how she got into drugs, but I have tried multiple times to get her into rehab. She objects. When it came time to graduate from high school, her wrong ways and drug abuse prevented her from doing so. With being unemployed, having no education, and always on some kind of drug, I see this friend having problem behavior syndrome. References: Criminology: The Core, Fourth Edition (Larry J. Siegel)

Bioaccumulation of Heavy Metals in Soil and Vegetables
Bioaccumulation of Heavy Metals in Soil and Vegetables Abstract The present study was carried out to assess heavy metals Cadmium (Cd), Lead (Pb), copper (Cu), zinc (Zn), Chromium (Cr) and Nickel (Ni) levels in vegetables like Cauliflower (Brassica oleracea var. botrytis), Cabbage (Brassica oleracea), Carrot (Daucus carota), Brinjal (Solanum melongena), Spinach (Spinacia oleracea) and Radish (Raphanus sativus) irrigated with domestic wastewater. The vegetable samples were randomly collected from the farmlands irrigated with domestic wastewater around the Hisar district. Spinach, cabbage, carrot, brinjal and carrot accumulated higher Cd (1.30Ãâà ±0.31), Pb (4.23Ãâà ±0.32 mg kg-1), Cu (1.42Ãâà ±0.25 mg kg-1), Zn (3.4Ãâà ±0.28 mg kg-1), Cr (1.16Ãâà ±0.11 mg kg-1) and Ni (2.45Ãâà ±0.86 mg kg-1) respectively. Transfer Factor (TF) of Cd, Pb, Cu, Zn, Cr and Ni are more in spinach (0.0306), cabbage (0.4448), spinach (0.2642), cauliflower (0.2494), carrot (0.0764) and spinach (0.7469) respectively. The health risk assessment has bee n calculated followed by Estimated Daily Intake Metal (EDIM) and Estimated Health Risk Index (EHRI). The present study highlights that both adults and children consuming vegetables grown in wastewater irrigated soils accumulate significant amount of these metals. However, the values of these metals were lesser than recommended maximum tolerable levels proposed by the FAO/WHO (1999). Keywords: Daily intake, Heavy metals, Plant uptake, Risk Assessment, Reference dose, EDIM, EHRI Introduction Indian economy is based on agriculture and having second largest population in the world. Most of its states are depends on the monsoon. There are two main sources for irrigation. First one is canal and second is ground water but the quality of ground water is so poor for the long sustainability of agriculture system. This water is not adequate to fulfill the crop water requirement and needs additional extra water for agricultural purposes. To cater the need of the present demand for irrigation, use of municipal domestic wastewater, is becoming a common practice in urban areas of Haryana, India. This causes serious problems of salinity and ultimately reduction in agriculture production (Marshall et al., 2007, Singh et al., 2010). The large amounts of untreated industrial and domestic wastewater are used for year round irrigation of vegetables. Such waste water usually contains heavy metals that accumulate in the soil. The use of such untreated wastewater has been reported to cause co ntaminations of the food chain (Wang et al., 2004; Mapanda et al., 2005). Some trace amount of heavy metals such as Zn and Cu are essential for the growth of organisms while others such as Cd and Pb are toxic (McBride, 1994, Kabata-Pendias and Mukherjee, 2007). Dietary uptake pathway could be through crops irrigated with contaminated wastewater and have been reported to contain large amount of toxic heavy metals which may lead to health disorders in humans depending on the uptake of these metals into plant and consumed by animals or humans (Bosso and Enzweiler, 2008; Fu et al., 2008; Lim et al., 2008; Agbenin et al., 2009). Consumption of metal contaminated vegetables may lead to a weakened immune system, intra-uterine growth retardation, impaired psycho-social behavior, high prevalence of upper gastrointestinal cancer and other disorders typically associated with malnutrition (Arora et al., 2008). Potential health risks to humans from consumption of vegetables can be due to heavy metal uptake from contaminated soils via plant roots as well as direct deposition of contaminants from the atmosphere onto plant surfaces (McBride, 2003). A number of previous studies from developing countries have reported heavy metal contamination in wastewater and wastewater irrigated soil (Cao and Hu, 2000; Mapanda et al., 2005; Nyamangara and Mzezewa, 1999; Singh et al., 2004; Nan et al., 2002). Dietary intake is the main route of exposure of heavy metals for most people (Tripathi et al., 1997). The information about heavy metal concentrations in different type of vegetables and their dietary intake is very important for assessing their risk to human health. Heavy metals in the nutrient cycle have seriously threatened health and environmental integrity, therefore, problem of heavy metal contamination in vegetables should be studied in details to develop central strategies. The objective of presen t study was bioaccumulation of heavy metals in vegetables irrigated by domestic wastewater and assessment of health rick due to these heavy metals. Materials and methods Study area and sampling All samples were randomly collected from the farmlands irrigated with domestic wastewater around the three different locations such as Rishi Nager (L1), New Police Line (L2) and Ludass village (L3) of Hisar district of Haryana, India. Soil samples were collected at the surface depth of 10cm using stainless steel spade sampling tools and plastic buckets to avoid any contamination of samples with traces of elements from the tools. At each sampling site, scrape away surface debris and remove a core sample to the appropriate depth. Soil samples were air dried, ground, passed through a 2mm sieve and stored in plastic bags for further analysis. Five ground Water and seven wastewater samples were also collected from the each location. All samples were collected and stored and kept at 4oC for further analysis in polythene bags/canes according to their type and brought to the laboratory for metal quantification. Sample preparation All the collected Vegetables were washed with double distilled water to remove airborne particles. The edible parts of the samples were weighed and soils samples were air-dried at room temperature, to reduce water content. All the samples were then oven-dried in a hot air oven at 70Ãâà ±5 oC for 24 h. Dried samples were powdered using a pestle and mortar and sieved through muslin cloth. Digestion of the vegetable and soils samples For each vegetable, three powdered samples from each source of domestic wastewater irrigation (1.0 g each) were accurately weighed and placed in crucibles, three replicates for each sample. The soil and vegetable ash samples were digested with perchloric acid and nitric acid (1:4) solution. The samples were left to cool and contents were filtered through Whitman filter paper No. 40. Each sample solution was made up to a final volume of 50 ml with distilled water and concentration of heavy metals were analyzed by atomic absorption spectrophotometer (ASS: model AA6300, Shimadzu). Risk Assessment Transfer Factor (TF) The transfer factor (TF) of Cadmium (Cd), Lead (Pb), copper (Cu), zinc (Zn), Chromium (Cr) and Nickel (Ni) from the soil to vegetables were calculated using below given equation 1(Cui et al., 2004; Gupta, et al., 2010): (1) Estimated Daily Intake of Metal (EDIM) The Estimated daily oral intake of metals from soil through vegetables in mg was calculated by equation 2: (2) Where; Cm is heavy metals conc. in vegetable plants (mg/kg), CF is conversion factor, DI is daily intake of vegetables (kg/ person/day) and BAw is Average body weight (kg). The conversion factor used to convert fresh green vegetable weight to dry weight was 0.085, as described by Rattan et al., 2005; Khan et al., 2008, Arora et al., 2008). The average daily vegetable intakes for adults and children were considered to be 0.250 and 0.150 kg/ person/day, respectively, while average body weights were taken as 55 and 25 kg of the age of 35 and 16 years respectively for adult and child. Estimated Health Risk Index (EHRI) Estimated health risk index (EHRI) is the ratio of estimated daily intake of metal (EDIM) to the reference dose (RD) is defined as the maximum tolerable daily intake of a specific metal that does not result in any harmful health effects. If the value of EHRI less than one than the exposed population is said to be safe and if greater than one indicating that there is a potential risk associated with that metal (IRIS, 2003) was calculated by below given equation: (3) Result and discussion Metal concentration level in water and soil The quality of domestic wastewater and ground water (tube well) was assessed for irrigation with respect to their pH, EC, OC and some of the heavy metals. The pH of the sewage water in the range of 6.8-7.3 (7.03Ãâà ±0.07) was lower than the ground water as collected from the nearby area in the ranged of 7.2- 7.9 (7.6Ãâà ±0.12) while its salt content (EC) was in the ranged of 175.8-195.3 mS/m considerably higher than those of ground waters (148.9-158.6 mS/m). The concentration for heavy metal contents in domestic wastewater and in ground water samples shows that Cd, Pb, Cu, Zn, Cr and Ni (figure 1) are well within the limits permissible limit set by FAO (1985) and PFA (2000). In general, concentrations of heavy metals were higher side in domestic wastewater than in the ground waters (Tube Well) which could be toxic to some crops and human health. In the studied area, the concentration of all the heavy metals in water and domestic wastewater were found to be higher except Zn fr om the permissible limits of Indian standards (PFA, 2000) and (WHO/FAO, 2007). The total concentrations of heavy metals (Cd, Pb, Cu, Zn, Cr and Ni) in soils sampled at the three different sites are presented in figure 2. The average pH of the location-I (7.04Ãâà ±011), location-II (7.02Ãâà ±0.19) and location-III (7.0Ãâà ±0.03) soil are almost nearly neutral. The electrical conductivity (EC) was 190.2-273.6 mS/m for location-I, 202.8-247.2 mS/m for location -II and 170-271.3 mS/m for location-III. The percent organic carbon contents in soil were higher due to constant domestic wastewater irrigation and ranged from 3.48-5.2% for location-I, 3.85-5.54% for location-II and 3-69-5.6% for location-III. As the sub soils were clayey the organic carbon was found to be in high percent. Soil organic carbon is the most important indicator of soil quality and in addition to acting as a store-house of the plant nutrients plays a major role in nutrient cycling (Rattan et al., 2005). Across the study area, wide ranges of soil heavy metal concentration were observed and are shown in figure 3. The observed concentration of heavy metal in ranged between 37.76-73.5 mg kg-1 for Cd, 2.74-22.44 mg kg-1 for Pb, 0.54-24.16 mg kg-1 for Cu, 0.96-12.44 mg kg-1 for Zn, 3.21-72.85 mg kg-1 for Cr, 1.37-6.47 mg kg-1 for Ni, and 249.3-773.4 mg kg-1 for Fe for location-I. For location-II, heavy metals ranged between 23.7-103.7 mg kg-1 for Cd, 5.67-30.99 mg kg-1 for Pb, 3.04-16.47 mg kg-1 for Cu, 3.16-9.16 mg kg-1 for Zn, 3.19-41.35 mg kg-1 for Cr and 4.68-13.77 mg kg-1 for Ni; 6.31-66.61 mg kg-1 for Cd, 3.20-19.60 mg kg-1 for Pb, 1.35-11.81 mg kg-1 for Cu, 4.47-15.55 mg kg-1 for Zn, 1.38-3.54-46.64 mg kg-1 for Cr and 1.38-9.99 mg kg-1 for Ni for location-III. The domestic wastewater irrigated soil in all locations, the heavy metal (Cd, Pb, Cu and Cr) concentrations was not significantly and for Zn and Cr is significant at (P The results have clearly indicated higher concentration of metals in soils which is contributed prolonged irrigation by sewage wastewater. If the same trend continues the concentrations of metals will accumulate in the soil. Relatively higher amounts of these heavy metal which attributes to the reduction in soil pH to moderately acidic conditions as well increase in organic carbon due to the continuous use of sewage effluents. This may be a cause of prime concern in near future. Long-term application of domestic wastewater will result in increase in organic carbon and decrease in pH. Heavy metal accumulation in vegetables The concentrations of heavy metals in edible part of vegetables (Table 3 and figure 2) were investigated in vegetables which is commonly grown. The bioaccumulations of heavy metals concentration in all the vegetables are different, so no similar trend have been observed for heavy metal concentration. The heavy metals bioaccumulation in cauliflower was Zn > Pb > Cu > Ni > Cd > Cr, for cabbage was Pb > Zn > Cd > Cr > Cu > Ni, for carrot was Zn > Pb > Ni > Cu > Cr > Cd, for brinjal Zn > Pb > Cd > Ni > Cr > Cu, for spinach was Zn > Ni > Pb > Cd > Cu > Cr , a similar trend have also been observed by Pandey and Pandey (2009) and for radish Zn > Ni > Pb > Cr > Cu > Cd. Cauliflower accumulated in the range of 0.15-0.27 mg kg-1 Cd, 0.14-0.34 mg kg-1 Pb, 0.7-1.75 mg kg-1 Cu, 2.9-5.9 mg kg-1 Zn, 0.10-0.35 mg kg-1 Cr and 0.01-0.60 mg kg-1 Ni, cabbage accumulated 0.30-1.20 mg kg-1 Cd, 3.37-5.37 mg kg-1 Pb, 0.06-1.10 mg kg-1 Cu, 0.74-4.90 mg kg-1 Zn, 0.06-1.23 mg kg-1 Cr and 0.01-0.34 mg kg-1 Ni, carrot accumulated 0.20-0.70 mg kg-1 Cd, 0.98-3.25 mg kg-1 Pb, 0.55-1.95 mg kg-1 Cu, 2.65-4.02 mg kg-1 Zn, 0.96-1.50 mg kg-1 Cr and 0.85-1.36 mg kg-1 Ni, brinjal accumulated 0.50-1.10 mg kg-1 Cd, 0.80-2.64 mg kg-1 Pb, 0.30-0.46 mg kg-1 Cu, 3.26-3.90 mg kg-1 Zn, 0.30-1.02 mg kg-1 Cr and 0.64-0.86 mg kg-1 Ni, spinach accumulated 0.7-1.88 mg kg-1 Cd, 1.26-3.8 mg kg-1 Pb, 0.90-1.45 mg kg-1Cu, 1.6-6.75 mg kg-1 Zn, 0.65-1.05 mg kg-1 Cr and 0.01-3.80 mg kg-1 Ni, and radish accumulated 0.22-0.38 mg kg-1 Cd, 0.64-1.24 mg kg-1 Pb, 0.19-1.30 mg kg-1 Cu, 0.56-2.70 mg kg-1 Zn, 0.76-1.25 mg kg-1 Cr and 0.21-2.40 mg kg-1 Ni. The range of Cd concentration in brinjal (0.50-1.10 mg kg-1) recorded in this study was lower than the range (1.10 9.20 ÃŽà ¼g g-1) reported by Sharma et al. (2006). Vegetables (spinach and cabbage), range of Ni concentration was highest in spinach (0.01-3.80 mg kg-1). These values were lower than the range (5.55 15.00 ÃŽà ¼g g-1) reported by Sharma et al., 2006 and Singh et al., 2010 in spinach from Dinapur area as well as the range (0.2 3.0 mg kg-1) in spinach from waste water irrigated areas of Hyderabad reported by Sridhara Chary et al. (2008). In cabbage concentrations of Pb, Cu, Zn, Cr, Ni and were lower during the present study as compared to those obtained by Sridhara Chary et al. (2008). The present concentration (mg kg-1) of 0.30Ãâà ±0.03 for Cd, 0.94Ãâà ±0.10 for Pb, 0.83Ãâà ±0.18 for Cu and 0.94Ãâà ±0.09 for Cr in radish were lower than the values obtained for radish collected from a suburban area of Zhengzhou city, Henan Province, China (Liu et a l. 2006). Khan et al. (2008) have reported higher concentrations of Cd, Pb, Cu, Cr and Ni and in radish plants grown at waste water irrigated areas of Beijing than the clean water irrigated ones. Among all the heavy metals, Zn concentration (4.26Ãâà ±0.06) was higher and Cr (0.09Ãâà ±0.07) was lower in cauliflower. Radwan Salama (2006) have also found highest concentration of Zn in vegetables collected from Egyptian markets. The bioaccumulation of Cd in spinach is higher than all the tested vegetable samples and similar result have also observed by Zhuang et al., 2009 in chaina. The bioaccumulation of Pb, Cu, Zn, Cr and Ni were found higher in cabbage, carrot, cauliflower, carrot and radish respectively. The results indicate that the concentrations of heavy metals in all the vegetables below the Indian standard (PFA, 2000) and (WHO/FAO, 2007). Heavy metal transfer factor Due to industrialization and urbanization, the heavy metal concentration of soil has increased worldwide. Soil-to- plant transfer of heavy metal is major pathway of human exposure to soil contamination (Chi et al, 2004). The high transfer factor from soil to plants indicates a strong accumulation of the particular metals by vegetable crops (Khan et al., 2008). The results indicated that TF values were lower for Cd, Pb, Cu and Cr, and higher TF for Zn and Ni from those. The transfer factor values in soil to plant of studied metals such as Cd, Pb, Cu, Zn, Cr and Ni for various vegetables varied between vegetable plants and locations are shown in table 4. The results revealed that there is large variation in transfer factor of Cd, than other metals in all three locations. The spinach (0.0306) had very high transfer factor for Cd and followed by brinjal (0.0207), cabbage (0.0165), carrot (0.0108), radish (0.0071) and cauliflower (0.0049). Similarly, The cabbage (0.4448), had very high tr ansfer factor for Pb and followed by carrot (0.2376), spinach (0.2187), brinjal (0.0207), cauliflower (0.1672) and radish (0.0988); The carrot (0.2977) had very high transfer factor for Cu and followed by, spinach (0.2642), cauliflower (0.2537), radish (0.1740), cabbage (0.0881) and brinjal (0.0818); The carrot (0.0764) had very high transfer factor for Cr and followed by radish (0.0619), spinach (0.0527), cabbage (0.0454), brinjal (0.0408) and cauliflower (0.0054) for location-III; The cauliflower (0.2494) had very high transfer factor for Zn and followed by carrot (0.1991), brinjal (0.1909), cabbage (0.1862), spinach (0.1739) and radish (0.0984) for location-II; The spinach (0.7469) had very high transfer factor for Ni and followed by carrot (0.4451), radish (0.4542), brinjal (0.2348), cauliflower (0.0732) and cabbage (0.0335) for location-I. The transfer factor of Cd, Pb, Cu and Cr is more in Location III, similarly, Zn in location II and Ni in location-I. Therefore, vegetable cr ops growing on polluted site can accumulate high concentrations of trace elements to cause serious health risk to consumers. Risk Assessment In order to check the health risk of any toxicity from wastewater, it is necessary to estimate the level of exposure of the heavy metals through food chain. In this studied six vegetables were selected and calculate the health risk assessment in terms of estimated daily intake of metal (EDIM) and estimated health risk index (EHRI) by considering the intake of metal through vegetables by the human being. Estimated Daily Intake of Metal (EDIM) The daily intake of heavy metals was estimated on the basis of the average consumption and concentration of metal in particular vegetable spices. The average concentration of Cd, Pb, Cu, Zn, Cr, Ni and Fe are shown in table 3. Based on the above concentrations, the estimated daily intake of metal (EDIM) for adults and children through food chain were calculated is shown in Table 5. The highest daily intake of metal such as Pb, Zn, Ni, Cu, Cd and Cr were from spinach, cabbage, cauliflower, spinach, carrot, spinach and Carrot respectively grown in domestic wastewater for both adults and children. The results of studied revealed that EDIM suggest that the consumption of vegetables grown in domestic wastewater polluted location is high but is free from any risk as the dietary intake of Cd, Pb, Cu, Zn, Cr and Ni in adults is below than the permissible limits (WHO, 1996). Estimated Health Risk Index (EHRI) In order to investigate the estimated health risk index (EHRI) associated with domestic wastewater irrigated soil, it is essential to estimate the level of exposure by quantifying the route of exposure of a heavy metal to the target person. The results indicate that the EHRI values were less than one for Cd, Pb, Cu, Zn, Cr and Ni in all tested vegetables consumption. Therefore, the health risks of heavy metals such Cd, Pb, Cu, Zn, Cr and Ni exposure through vegetables was no consequences and generally assumed to be safe. All the estimated dietary intake of Cd, Pb, Cu, Zn, Cr and Ni were far below the tolerable limits. The oral reference dose (RD) for Cd, Pb, Cu, Zn, Cr and Ni are 1.0E-03, 3.5E-03, 4.0E-02, 3.0E-01, 1.5E-00 and 2.0E-02 mg kg -1 day -1, respectively given by US-EPA (2002), IRIS (2003). The results of the study showed that EDIM and EHRI suggest that consumption of vegetable grown in polluted soil irrigated with domestic wastewater is nearly free of risk. But there are a lso other sources of metal exposure such as dust inhalation, vehicular exhaust which were not include in this study. Conclusion The prolonged domestic wastewater irrigation increases heavy metal accumulation in the soil has lead to contamination of food crops in the study area. This study shows that edible vegetables shows significant bioaccumulation of heavy metals in vegetables grown in sewage wastewater irrigation. These vegetables are supplied to local markets and there is possibility of health hazard associated with consumption of these contaminated vegetables over a long period of time. The concentration of all heavy metals in domestic wastewater was found to be higher except Zn from the permissible limits of Indian standards (PFA, 2000) and (WHO/FAO, 2007). The results indicated that higher concentration of metals in soils which is contributed prolonged irrigation by sewage wastewater. If it is continues, the concentrations of metals will accumulate in the soil. Relatively higher amounts of these heavy metal which attributes to the reduction in soil pH to moderately acidic conditions as well increase i n organic carbon due to the continuous use of sewage effluents. The concentration of heavy metals in all the vegetables is lesser than Indian standard (PFA, 2000) and (WHO/FAO, 2007). The transfer factor of Cd, Pb, Cu and Cr is more in Location III, similarly, Zn in location II and Ni in location-I. Therefore, vegetable crops growing on polluted site can bio-accumulate high concentrations of trace elements to cause serious health risk to consumers. The highest daily intake of metal such as Pb, Zn, Ni, Cu, Cd and Cr were from consumption of the spinach, cabbage, cauliflower, spinach, carrot, spinach and Carrot respectively grown in domestic wastewater for both adults and children. The results of studied revealed that EDIM and EHRI suggest that the consumption of vegetables grown in domestic wastewater polluted location is high but is free from any risk. Therefore, the health risks from the heavy metals such Cd, Pb, Cu, Zn, Cr and Ni exposure through vegetables was no consequences and generally assumed to be safe. Therefore, in order to reduce risks, plants with lower accumulative nature should be grown. In this scenario the present study significantly indicating the need for proper treatment and disposal of domestic wastewater with low cost and worldwide acceptable technology.

Masaccio: Innovator of Perspective and Illusion Essay -- essays resear
Masaccio: Innovator of Perspective and Illusion Considered the greatest Florentine painter of the early 1400s, Masaccio is one of the most important figures of Western Art. Tommaso di ser Giovanni Cassai di Simon Guidi was born in 1401 and nicknamed Masaccio Careless Tom because of his attitude. He was apathetic to things like personal appearance and worldly materials, and was thus careless with his possessions. As a child, he concentrated more on his art instead of himself and what others thought about him. He moved from Castel S. Giovanni di Altura to Florence in 1417 to become a pupil of Masolino di Panicale. There, he helped upon innovations of art. In 1422 and 1424, he enrolled in the guild of St. Luke of Florentine Painters. After becoming jaded at the medieval art, Masaccio wanted to make art more realistic and true to life. He constantly studied the idea of perspective in an effort to make his paintings appear natural. Few paintings can be undoubtedly credited to Masaccio, but these are considered masterpieces nonetheless. His greatest work was done on the frescoes in the Brancacci Chapel of Santa Maria del Carmine in Florence. These frescoes were started by Masolino and ultimately completed by Fillipinno Lippi years after Masaccioââ¬â¢s death. This chapel is now a significant monument in the history of art. These frescoes had a tremendous impact on Florentine art thereof, and were used as a basis to teach new artists like Michelangelo and Raphael. It is on these wall...

Essay --
Question Ferguson, N. (2013). The Great Degeneration: How Institutions Decay and Economies Die. .Honig, Bonnie. Emergency Politics: Paradox, Law, Democracy. Princeton: PrincetonUniversity Press, 2009. Ferguson highlights in his paper that the current generation is misusing resources and as a result pile up the debts and heap burden upon the future generation. To avert this amongst the many things he mentions is good leadership to enforce the regulations in place to avert the disaster pilling up. Hence therefore we are forced to assess what leadership is good for sustainable utilization of resources that takes into consideration the future generations. What Ferguson highlights is very relevant to the society today because politics and leadership of nations is really affecting the development of many nations. The way countries are being run directly reflects on the development progress in the countries. Study of leadership therefore becomes an interesting component for study so that we can be able to build up on the need for sober leadership for the development of nations. Of interest in Fergusons highlight is the fact that he highlights the negligence with which resources are being utilized without consideration for the future generations who are also heavily dependent on how well we preserve the resources for them. Compromise in terms of the implementation of regulations and policies as highlighted by Ferguson seems to be the core undoing of the leadership in place which leaves the nations vulnerable in terms of their economies and sustainability. The research therefore will strive to highlight the importance of leadership in nations with special reference to the resource allocations, utilization as well as sustainability. In the... ...p is a craft that is made and the way it is made determines the output. The fact that leaders learn and grow means that the leaders are made and not that a person id born with a leadership calling in him or her. Conclusion In as much as each and every leaders has a different approach to leadership, there are attributes that are commonly shared amongst all these leaders. Approaches might be different but the goals intended to be achieved are the same. All leaders have qualities that stand out and make them better in their leadership or management. Despite using different approaches to achieve the goals and objectives, the qualities they share remain constant across board and hence the similarity in their success as the unique end results of their roles. Resources utilization should be done sustainably under the watch of the leadership considering future generations.
The relationship between multiplication and addition Essay -- Educatio
Teachers should know and understand the relationship between addition and multiplication because this understanding will translate well into teaching students to understand the concept of multiplication. The relationship of these two operations is very close so it is especially important to ensure each student fully comprehends the rules of addition before proceeding to multiplication. Addition is the process of combining a number of individual items together to form a new total. Multiplication, however, is the process of using repeated addition and combining the total number of items that make up equal-sized groups. This means that in multiplication, groups are created to represent the numbers being multiplied, and then the groups are added together to produce a total. Relating addition to multiplication is relatively simple. In fact, instruction on multiplication often begins in kindergarten as children develop ideas about numbers, addition, and groups. These experiences provide the basis of understanding for multiplication. Because addition is a precursor for multiplication, a student must be able to count items in groups and count the number of groups, which will then help them to be able to multiply them. Through the addition principles of skip counting, repeated addition, grouping, and number lines students can attain a deeper, broader understanding of multiplication. When students finally understand that multiplication and addition function under many of the same rules or properties, they will understand that addition and multiplication work under the same conditions. The strategy called skip counting will benefit students who know how to count by two's, five's or ten's. Drill exercises using skip counting... ... are computing using the distributive property will get them using the language of math, help them to see where they are making errors, and help them by having a peer agree or disagree with their answer. If the pair has different answers, they can re-work the problem using the distributive property to see who is correct. Sharing answers with the rest of the class will reinforce the correct procedure, thus reinforcing the property. Teaching multiplication can be made less confusing for the students when the relationship between addition and multiplication is communicated and explained. Building upon prior knowledge of the use of addition strategies and incorporating the properties of multiplication, the students can reach a depth of knowledge about multiplication that will make it possible for them to discover the correct product and reinforce both concepts.

An Essay on the Presidential Candidates of 2000
When examining the candidates for the 2000 Presidential election, it becomes very clear that the only logical choice for President is Al Gore. Gore has many plans for his presidency that will greatly improve the way our country works and runs. First of all, Gore wishes to reform the way in which elections are run, and attempt to sever the omnipresent link between money and political influence, thus providing more fair elections. Another plan of Goreâ⬠s is to set aside 400 billion dollars especially for Medicare, and to make sure the money is not used for other purposes, thereby improving the lives of both the elderly and the less fortunate. In order to better the lives of all citizens and provide for more safety, Gore also wishes to close the so-called ââ¬Å"gun show loopholeâ⬠that allows consumers to bypass the Brady Bill. Lastly, to better equip the children of today for the world of tomorrow, Gore intends to reform education by providing preschool for all children, and making college tuition tax deductible. The first of Al Goreâ⬠s many changes he has in store for our country could possibly be the most important one. Gore seeks to change the very way we decide on and elect our officials who run the country, and he intends to do so in a way that ensures a more fair and equal election. What is the key to this electoral equilibrium? Money. For a long time people and political analysts have noticed a certain trend coinciding with a candidateâ⬠s political influence and how much money he has at his disposal. Traditionally, the candidates with more money get more exposure to the public, get more high influence individuals and agencies backing them up, and therefore end up with more votes than those candidates with less cash. Severing this link between politics and money would be a wonderful change for our country. One of the main ways in which Gore intends to increase equality among presidential candidates is to ban ââ¬Å"soft money. â⬠Soft money is money contributed to a candidate by companies or individuals in order to boost their campaign. In place of this money, Gore intends to establish a tax-free foundation to fund campaigns, thereby supplying each candidate with the same amount of money to campaign with as he/she pleases. This fund will accept tax-deductible donations from companies and individuals, and then give each candidate their equal share. It is estimated that this foundation, called the Democracy Endowment, will raise 7. 1 billion dollars within a seven year period, while only suffering a loss of 2. 1 billion in taxes. This equal-endowment plan will even the playing field for the candidates, and give each an equal opportunity to campaign. In addition to equal campaign funding, Gore supports the idea of allowing each candidate an equal amount of free air time on television to campaign with. This, too, will give each candidate an equal chance to be heard, independent of how much money he/she has. These proposals, among his others, will help to sever the link between money and political influence, change the way elections are run, and provide for more fair elections. Another major problem that plagues millions of Americans today is the issue if Medicare. Medicare is the government health insurance program for the elderly, and provides care for about 40 million seniors annually. In recent years, much attention has been called to this program regarding its coverage. The general sense is that Medicare is not adequately insuring its seniors. One cause of this decline in coverage is the money allotted to Medicare. Many times, when other projects start to run over their budget, the politicians ââ¬Å"dip into the cookie jar,â⬠and take small amounts here and there from the Medicare stash, leaving our seniors with less than adequate medical coverage. Gore wants this to stop. His plan that he wishes to implement sets aside 400 billion dollars strictly for Medicare, and ensures that this money cannot be used for other purposes. This will mean guaranteed improvement of the medical treatments and attention those covered will receive. In addition to the 400 billion dollars, Gore has plans for a 253 billion dollar, 10 year program to add a prescription drug benefit to further aid Medicare users. These programs will definitely improve the living conditions of what is fast becoming the largest percent of the American population. Gore does not stop at improving living conditions for the elderly. He recognizes many ways of raising the quality of life for all US citizens, one of them being in the area of safety. In an effort to make our country a safer place to live, Gore intends to close the so called ââ¬Å"gun show loopholeâ⬠that essentially allows consumers to buy assorted weapons and handguns without waiting periods or background checks, completely bypassing the Brady Bill. A report released by the Justice Department found that felons illegally bought weapons at gun shows in 46 percent of the 314 cases it studied, and the weapons used in the 1999 shooting at Columbine High School in Colorado were purchased at a gun show in Denver. Closing this loophole would mean fewer weapons in the hands of people who shouldnâ⬠t have them, and therefore safer places to live everywhere. It would be foolish not to enact this change, therefore making it foolish not to vote for Gore. The last key issue on which Gore has many great ideas has more impact on the future than any of his other plans. This issue deals with education. Over the last 20 years, spending on education has risen 62 percent, yet we have experienced a 7 percent decline in enrollment. Studies have shown that giving children a good educational start in the beginning is an excellent way to aid their future in the education department. That is precisely why Gore wants to provide preschool to all children. Giving them a solid start in their earliest years instills the basic principles of behavior and learning skills necessary to be successful in the education system. But, of course, learning skills can only get you so far once you reach the college level. All too often, bright young students do not get to attend college due to a lack of sufficient funds. This is a contributing factor to the difficulty of breaking the chain of poverty. Gore recognizes this, and plans to make college tuition tax deductible. This will soften the blow of tuition check on the lower class families, and allow a greater variety of students from all sorts of backgrounds to further enrich their minds. By doing this, the future of our country will brighten tremendously, as we will have a multitude of new, brilliant minds at work everyday. Education truly is an investment in the future, and Gore knows how to ensure profitable returns. By examining these key points in Goreâ⬠s plans for the country, It is obvious that he has the welfare of all citizens on his mind, and that his plans would effectively improve the way our country runs. With that in mind, Gore seems to be the only logical choice for President of the United States.

Character Analysis on Boxer (Animal Farm) Essay
Horses are well known for their strength and Boxer is no different and he lives up to the expectation of being a strong male horse. Boxer is an almost blind follower to the farm and whoever is in charge of it. His almost unreal strength is a great asset to the rebellion and to the farm as he is capable of working harder than any animal. As soon as he learns about Animalism, Boxer makes himself available to do anything for the rebellion. After the rebellion at the Battle of the Cowshed he proves once again how irreplaceable he is to the farm, as he proves he is a valuable soldier but he shows us that he is a kind and gentle soul as he feels pain when he thinks he has killed the young farm boy. He wakes up early everyday so that he can get more work done around the farm as he gives himself the job of making the farm a better place for his fellow animals. He adopts the maxim ââ¬Å"I will work harderâ⬠. This leads him to do great things such as building the windmill twice almost on his own. Unfortunately, Boxer does have the intelligence that we so wish would match his strength (this is clear when he is unable to learn the alphabet past the letter ââ¬Å"Dâ⬠). He is actually very naà ¯ve and innocent and this leads him to be easily confused and taken advantage of by the pigs and Napoleon. After being taken advantage of many a time, Boxer eventually adopts a second maxim, except this maxim eventually leads to his downfall: ââ¬Å"Napoleon is always rightâ⬠. Boxer shows devotion like no other to the progression of the farm and this is evident when he collapses as he states ââ¬Å"It is my lung â⬠¦. It does not matter. I think you will be able to finish the windmill without me.â⬠Even when boxer collapses and is close to death, he is still thinking of his work, his fellow comrades and how he can help make the farm better for when he is no longer capable to do more. Sadly for us, Boxer does not seem to grow wiser with age, and even when he is being taken away by the knacker, he needs to be told what is happening before he tries to do something about it. When he realises whatââ¬â¢s happening he gets to his feet and tries to kick down the door of the cart but is unable. This is a sad image and a sad end to Boxer as ââ¬Å"there used to be a time when one swift kick of Boxerââ¬â¢s hooves would have kicked down the cart wall with easeâ⬠. How fitting is it that such a great animal like Boxer, would be put to death in such a cowardly way and by the animal that he trusted and listened to the most, Napoleon. BOXERââ¬â¢S REPRESENTATION IN REAL LIFE Boxer represents the working class, a person of no great intelligence but very capable and reliable abilities in work that required labouring. He spends his time in the novel helping with the revolution, and then the pigs. Everything he does, he does to the best of his ability, he does this because he knows that his own hard work will result in a better farm for all animals. However, because Napoleon and the pigs view the other animals as workers for their benefit instead of equals, Boxerââ¬â¢s work is never rewarded; when he becomes injured and unable to work, Napoleon sells him to the knackers instead of letting him retire as promised.
