Autism and Social Skills Essay Example for Free

Autism and Social Skills Essay Autism spectrum disorder is a neurodevelopmental disorder that ranges from mild to severe impairments in communication, social interaction, and repetitive pattern of interest. Children with autism need early social skills support to develop their social interactions and understanding. Autism spectrum disorders (ASD) and socialization among young children and adolescence is one of the major impairments, along with language individuals have. Social skills groups are prearranged groups with, a direct goal orientated to engage young children and adolescences with the appropriate support, in the development of social skills. Social skills groups for young children and adolescences can be a viable tool, in helping children with ASD to learn how to socialize appropriately. The Socialization of young children with a diagnosis of ASD has shown some positive results. This pilot study was conducted in response to the heightened awareness and the need for young children with ASD to learn social skills. The parents of autistic children, the children that have a diagnosis of ASD and the facilitators of the groups, will engage the children in social sessions, in hopes to build social relationships. The parents will fill out questionnaires as to the progress they see their children making. This pilot study sets out to answer the following two questions. Is participation in a social skills group beneficial for young children / adolescence with ASD from the child’s, Parents and the facilitator’s perspectives? The second question posed was, is there any improvement in the autistic child’s ability to communicate or interrelate socially. Methodology Based on a review of literature on Autism, a psychologist and a clinical psychologist planed a structured 5-week program, for one-hour sessions, one day a week. Only children with a diagnosis of ASD were invited. The children’s ages ranged from seven to 18. Using the qualitative method, the parental focus group was used to gather data and answer two research questions. Each parent received three questionnaires developed for the purpose of this evaluation. One was a pre- questionnaire, to be completed at the beginning of the groups, the post questionnaire, at the end of groups, and a review questionnaire, to be completed six months following the social skills groups. The questionnaires were used for the parents to rate their child’s current level of difficulties. Results and Discussions The high cost of one on one therapy for autistic children has become too high for caregivers and the need for alternative approaches was necessary. Evidence suggested that social skills groups for autistic children would be an alternative Dunlop, Knott and Mackay (2000). The information gathered from parent questionnaires and through observations from the facilitators and the higher functioning adolescents with ASD showed there was a need for social skills programs. Some parents felt their children benefitted and others seen no change. The feedback was very positive and most of the participants would like the social skills groups to continue. There were several areas identified within the program that needs fine-tuning such as, smaller groups, the level or severity of ASD the children have, longer duration of sessions without summer breaks and addressing how to manage the challenging behaviors some of the autistic children displayed, which prevented them from engaging socially within the groups. There was no time for one on one interaction, to encourage those children that did not socialize during the five-week program. The facilitators observed this and felt that it was an important issue to address along with the other recommendations above, when planning social skills programs. I choose this article because I am a parent of an autistic child and I am always looking for new treatment methods. I like to stay informed of all the new research on autism to share with my son. I think there is a need to socialize all persons with autism and the ideal of social skills groups cannot hurt; it can enhance the quality of life for the autistic child.

Benefits of Telemedicine

Benefits of Telemedicine Introduction Long waiting time and extensive travelling costs have been some of the most significant problems faced by the public health around the world. These long wait lists and travel costs are not only a hurdle to the patient but also to the economy, resulting in considerable productivity loss. These issues have been addressed in a number of researches, recommending various strategies and policies (British Columbia Medical Association, 2006; Adamu Oche, 2013). However, technology can play a vital role in eliminating travel costs and waiting time by implementing telemedicine. Telemedicine can be defined as â€Å"The delivery of health care services, where distance is a critical factor, by all health care professionals using information and communication technologies for the exchange of valid information for diagnosis, treatment and prevention of disease and injuries, research and evaluation, and for the continuing education of health care providers, all in the interests of advancing the health of individuals and their communities† (WHO, 2010, p.9). It is especially beneficial for people residing in under-developed, less economically developed or remote and rural areas of developed countries that lack basic or specialist healthcare. It is an effective means of reducing travel costs as well as consultation wait time (Ontario Telemedicine Network, 2012). Background Telemedicine is a relatively new field and has the potential to address various barriers in administration of quality healthcare and enable equitable access to health. However, cost-effectiveness studies are of supreme importance for wide adoption of telemedicine and to convince physicians and policy makers of its effectiveness. Without any information on the cost-effectiveness of telemedicine policy makers, decision maker, implementers run the risk of supporting telemedicine systems that are not perceptive to healthcare needs of the patient and which do not provide cost-effective services either from patient or provider perspective (Hailey, 2005). Most of the empirical studies on cost-effectiveness of telemedicine are either based on assumptions, weak evidence and inadequate details on study design and methodologies or narrow perception on the outcome. Whitten et al. (2002) undertook a systematic review of cost effectiveness studies, and identified several articles that met their se lection criteria. Most of the studies provided no details of sensitivity analysis, none employed cost utility analysis and no study adequately compared telemedicine services to traditionally organized health care. Thus, concluding that â€Å"there is no good evidence that telemedicine is a cost effective means of delivering health care† Telemedicine costs are mainly determined by the scale and utilization of the service. For example, if a large number of patients use telemedicine service, the cost of the service would significantly decrease. Mistry (2011) highlighted that many studies fail to define what is meant by cost-effectiveness or provide a cost-effectiveness threshold. Furthermore, his analysis defined that cost-effectiveness of telemedicine depends not only on the service being assessed, patient group and sample size, type of economic analysis and how the costs and outcomes are measured, but also on the take-up rate and the usage of the service. Cost-effectiveness of telemedicine may vary according to it usage in sub-specialty such as teleradiology (WHO, 2010), telepsychiatry (Spek et al., 2006), teledermatology (Loane et al., 2001) etcetera, as concluded by a systematic review that the potential effectiveness of telemedicine could only be credited to teleradiology, telepsychiatry, transmission of ECHO images and consultations between primary and secondary health providers (Roine, Ohinmaa Hailey, 2001). According to a systematic review by Wade, Karnon, Elshaug Hiller (2010), real-time telemedicine was cost-effective for home care but not for local delivery of services between hospitals and primary care. Similarly, in a cost study by Lamminen, Lamminen, Ruohonen Uusitalo (2001) concluded that benefits and savings attained through teleconsultations included reduction in travel costs and paperwork as well as time savings for the patient, with an addition benefit of improved medical learning. Use of telemedicine in chronic pain management has yield worthwhile results as patients suffering from chronic pain often find it back-breaking to travel long distances for treatment. Telemedicine delivered to such patients for pain management, irrespective of their geographical location, were 56% satisfied as compared to the 24% of traditional in-person clinical visits, resulting in significant cost advantage for patients and attendees (Pronovost, Peng Kern, 2009). Pronovost et al. (2009) also inferred that significant improvement on a patient’s financial budget was a likely factor for greater degree of telemedicine patient satisfaction as compared to in-person clinical visit group. Chan, Woo, Chan Hjelm (2000) in a study for cost effectiveness of geriatric teledermatology concluded that travelling to see a dermatologist is a hurdle, for the elderly and disabled patients, which can be cost effectively resolved by teledermatology. Hayward Mitchell (2000) in their cost effec tiveness study for teleradiology identified tangible benefits from patient perspective as reduced costs of travel and accommodation, need for childcare and time off from work. Intangible benefits included faster management of medical problems, reduced anxiety as second opinion is rapidly provided, equitable access to specialist level opinion. A retrospective study from 2005 to 2012 examined the cost effectiveness of telemedicine diabetes consultations and concluded that telemedicine setup was associated with improved cost effectiveness and patient satisfaction. It emphasizes that patient satisfaction was primarily related to the major decrease in travel time, which accounts to a full working day (Levin, Madsen, Petersen, Wanscher Hangaard, 2013). A systematic review on cost comparison between telemonitoring and usual care of heart failure reported that all studies reviewed found a reduction in costs that ranged from 1.6% to 68.3%. These cost reductions were largely attributed to reduced hospitalization and travel costs. It was found that 55% of the patients were willing to pay $20 and 19% were willing to pay $40 to access telemedicine instead of traveling to the physician’s office (Seto, 2008). Similarly, a study reported 24% cost saving; of cost per year; of patients using telemedicine (Zanaboni et al., 2013). Transportation savings using telemedicine have been noted in several studies- Maass, Kosonen Kormano; James Folen study (as cited in Whitacre, 2011, p.176). Thaker, Monypenny, Olver Sabesan (2013) included various costs in their cost savings teleoncology model; from one-time costs to running costs; and found that it provides considerable savings, compared to the usual mode of healthcare delivery. Savings were attributed to reduced patient travel, along with an escort, to a tertiary center, avoiding of overnight accommodation, aeromedical retrievals as well as reduced visits from a specialist. It emphasizes that the net savings are mainly due to reduced patient travel and this model can be applied to geographically distant rural areas, which require lengthy travel. Research has shown that the availability of telemedicine allows rural areas to offer a larger variety of healthcare services, improve the overall perception of healthcare quality – Ricket’s study (as cited in Whitacre, 2011, p.172) and increases equality between citizens as medical expertise becomes available irrespective of patient location (Maass, Kosonen Kormano, 1999). It impacts the economy of a rural community by reducing travel that lowers transportation costs and decreases missed time from work; increases local pharmacy and lab work and provides saving to the hospital by out-sourcing telemedicine procedures. Increase in local pharmacy and lab work has a financial impact on the local economy which is mainly because telemedicine patients do not leave their local areas to receive their original diagnosis hence any resulting follow-up work ends up at the local pharmacy or lab (Whitacre, 2011). One of the major points of telemedicine adoption is abridging distances thus reducing productivity loss and delivering high quality health care outside the healthcare center. It highlights that since telemedicine reduces the number of visits, it consequentially reduces travel expenses as well as productivity loss (Fusco, Trieste Turchetti, 2013; Deshpande, Khoja, Lorca, McKibbon, Rizo Jadad, 2008).

A Review Of Controlled Release Fertilizers Biology Essay

A Review Of Controlled Release Fertilizers Biology Essay In general, plants must be supplied with nutrients during the whole vegetation period. In horticulture this is achieved by applying quickly soluble fertilizer once to twice a week, for example. This kind of fertilizer application is very labour-intensive and requires considerable specialist knowledge, so as to select the correct rate of application, appropriate time of application and correct composition for the particular plants to ensure optimum plant production. With the use of slow or controlled release fertilizers the full amount of nutrients necessary for the whole vegetation period can be applied at the time of planting or at the earliest stages of plant growth, in the form of a nutrient pool Also, about half of the applied fertilizers, depending on the method of application and soil condition, is lost to the environment, which results in the contamination of water [1].This kind of environmental concerns of feeding crops with traditional fertilizers has led to developing Slow Release Fertilizers (SRFs) or Controlled Release Fertilizers (CRFs). SRFs or CRFs are easy and safe to use. They reduce risk of incorrect fertilizer application; they are labour saving; and minimize nutrient losses by leaching or fixation. The idea of producing SRFs was developed from 1963 by encapsulation of fertilizers by waxes. After that, these products have been commercialized. There are lots of SRF and CRF brands; market leader in controlled release fertilizers is Scotts Professional with key brands such as Osmocote Exact, Sierrablen and Osmoform. SunGro Company is also producing controlled release fertilizers with brand name of Multicoate. AGLUKON is also another commercialized SRF product [2-4]. Like lots of scientific fields, agriculture industry has been over shadowed by nanotechnology. Applications of nanotechnology in agriculture includes agriculture crop improvement, nanobiotechnology analysis of gene expression and regulation soil management, plant disease diagnostics, efficient pesticides and fertilizers, water management, bioprocessing, post harvest technology, monitoring the identity and quality of agricultural produce and precision agriculture[5]. Efficient pesticides and fertilizers in terms of Nano-composite based slow release fertilizers are developing in current decades. Using nanoparticles as reinforcing or cementing agent of polymer coatings has been the only feature of nano particles which is used in preparing slow release fertilizers [6,7]. Fertilizers Fertilizers are applied to soil to promote plant growth. They contain some beneficial nutrients including macronutrients and micronutrients. Macronutrients are nitrogen, phosphorus, and potassium which are added to soil in quantities from0.2% to 4.0% (on a dry matter weight basis) and are more essential than micronutrients. Micronutrients are elements which are applied to soil in much smaller amounts, ranging from 5 to 200 ppm, or less than 0.02% dry weigh. These elements could be sulfur (S), boron (B), copper (Cu), iron (Fe), manganese (Mn), molybdenum (Mo), zinc (Zn)[8,9]. 2.2. Types of fertilizers Fertilizers would be categorized from source of being and also from release properties points of view. All fertilizers could be organic or synthetic from source of being point of view. Organic fertilizers are naturally occurred including seaweed, worm casting, manure, slurry, peat, humic acid, guano and brassin. They provide slow release of nutrient as they need soils bacteria to be broken down to needed elements. Also, they may improve the biodiversity of soil by supplying organic matters and micronutrients for organisms. Organic fertilizers are cheaper and safer than synthetic fertilizers [9,10]. The main synthetic or mineral fertilizers are urea, ammonium sulphate, ammonium phosphate, phosphate rock, potassium chloride, super phosphates, calcium ammonium nitrate, potassium sulphate and NPK, PK and PK compound fertilizers. The most important drawbacks of synthetic fertilizer is their long term sustainability. Also, they are more expensive in contrast to organic fertilizers [10]. Also, fertilizers can be categorized into ordinary and controlled release fertilizers from release properties points of view. Drawbacks of non- controlled release fertilizers Ordinary fertilizers leach to soil very quickly and most of them are not used by the plants. According to figures about 40-70% of nitrogen, 80-90% of phosphorous, and 50-70% of the applied normal fertilizer is lost to environment and cannot be used by plants[11]. This rapid leaching will cause burning of plants and growing in spurts. Also, the lost elements will make some serious problems for our environment. Eutrophication, Blue baby syndrome, soil acidification, persistent organic pollutants, heavy metal accumulation, atmospheric effects are environmental concerns of ordinary fertilizers. Another result of quick leaching of fertilizer is repeating the application of fertilizers which will increase the costs[8,12,13]. Slow or controlled release fertilizers Slow release fertilizers or controlled release fertilizers are coated in a substance that enables a slow release time and eliminates need for constant fertilization and higher efficiency rate than soluble fertilizers [14]. The interest in these materials is for one or more of the following reasons: Availability of nutrients during the hole growing-season; reduced nutrient loss via leaching and run-off; reduced cost and labor outlay in crop production; reduced chemical and biological immobilization reactions in soil which cause plant unavailable forms; reduction of rapid nitrification and nitrogen loss through ammonia volatilization and denitrification; reduced seed or damage from high local concentrations of salts; reduced leaf burn from heavy rates of surface-applied fertilizers; better seasonal distribution of growth and better acclimatization in home or display environment; improved storage and handling of fertilizer materials[15]. Differences between slow and controlled release fertilizers Although there is no a special difference in general function of CRF and SRF, but it should be mentioned that they are manufactured by different materials and techniques with different properties. In slow release fertilizers elements are present in the fertilizers in a chemical form, which is not available to plants and they will be converted by physiochemical effects or microorganisms activities into nutrient forms in the soil. But in controlled release fertilizers elements are packed in coated granules and are released through the coating over a certain period of time. Also, in SRFs nutrients available period is affected by a lot of factors such as water content of soil, Ph, temperature, microorganisms activity, aeration. However, the longevity of CRF depends on coating thickness and temperature of soil. Only coating method is effective in changing pattern of nutrients release and a fixed coating thickness control nutrients release. In CRFs declared release time refers to soil temp erature of 20-21 oC. Higher temperatures accelerate the element release and lower temperatures make it longer [4,16]. SRFs are chemically prepared slow released. Some kinds of SRFs are Urea Aldehydes (UA) and Chelated Micronutrients(CM). Common type of UAs is urea formaldehyde which is high nitrogen fertilizer. Starting release rate of UAs is high but it dies off slowly for 3 years. This kind of fertilizer depends on microorganisms to break it down for plant use. CMs are substances that hold firmly together iron, manganese, zinc, and copper. They slowly releases over a long period of time [17]. 2.4.2. Types of CRFs 2.4.2.1. Sulfur Coated (SC) Elemental sulfur when is oxidized to its sulfate form would be one of the nutrients which is essential for some plants and is normally blended with other fertilizers. Using sulfur coating is also another way to provide sulfur simultaneously with making slow release properties for a core granular fertilizer. As the sulfur containing materials like polysulfides or lingosulfonate are brittle and also give a low wetting of defects they are normally mixed with waxes or plasticizers. Many formulas are available for SCs. Their release time is generally 3-4 months. SDs are released by microorganisms [18-22] 2.4.2.2. Wax coated (WC) One of the methods of reducing fertilizer release rate is dispersing granular fertilizers with molten wax and then cooling the mixture below the melting point of the wax [23]. Paraffin is one of the most used wax as a coating for fertilizers. Paraffin  wax   is a white, tasteless, odorless, waxy solid, with a typical melting point between about 47  °C and 64  °[24]. Other types of waxes are synthetic oil based, petroleum or mineral waxes. Waxes are normally used by an additive or a tackifiere agent to make a good sealing properties [25,26] 2.4.2.3. Polymer Coated (PC) Polymer-coated fertilizers (PCF) represent the most technically advanced controlled released fertilizers. They include a water-soluble fertilizer core and one or more than one layers of polymer. There are large varieties of polymers to coat the core fertilizer also the coatings layer could be the same one or different. In PC fertilizers release of nutrients will happen by diffusion through a semi permeable polymer membrane. Water penetrates the coating and dissolves the core. Release rate can be controlled by varying the composition and thickness of the coating. In addition, pressure builds up can cause cracks to form, from which fertilizer passes into the soil [27, 28]. 2.5. Review of preparation methods of different polymer coated CRFs 2.5.1. Sole Polymer coated One type of polymer coated CRFs is the one which the fertilizer core which could be N, P, K OR NPK compound, is just coated with one or more than one layer of polymer coating. In this case the polymer could be solvent based or water-based. The application process starts with dissolving the polymer in a organic solvent or water. After dissolving the coating will be sprayed onto the fertilizer in a coating drum or fluid bed [29]. Benefits of polymer coated CRFs are as follow; uniform and defect free coating will surround fertilizer; the coating will be very tough and durable which is resistant against mechanical breakdown; they are biologically inactive so they will not breakdown by soil microbes. In most cases except for degradable polymers release of fertilizers will be happen by diffusion through polymer coat rather than through defects. In some other coated fertilizers like sulfur coatings there should be a flaw in coating to make release of fertilizer. There are lots of examples for polymers which have been used in literatures as coating for fertilizers, some of them are as follow; dicyclopentadien[30],Urea and urethane based [31-36], epoxy based [ 37-39], polyvinylidene chloride-based latex[29] carboxyl-carrying ethylene polymers[40], biodegradable starch based[41], urea formaldehyde[42]. However, polymer coated fertilizers have some week points. About solvent-based coatings using large amount of organic solvents like toluene or xylene will lead to environmental concerns. These solvents are volatile and releasing them to environment makes some hazards for human health. Also, polymer coatings are more expensive than sulfur coatings; the process and equipments are also more complex than equipments used for other coatings. 2.5.2. Sulfur-polymer coated One of most common coated fertilizers are the ones in which core fertilizer is covered by a layer of sulfur coating and a layer of polymer. The polymer layer can be primer or outer layer; means that sulfur layer in some researches has been the first layer and in some others the outer layer. Sulfur Using coating is a suggested method to remove drawbacks of sulfur coated CRFs. One of these drawbacks is very fast release of fertilizer in first few days after application. The other one is brittleness of sulfur coatings which may lead to some fractures during handling or storage and losing the fertilizer into soil. Another problem is that sulfur coatings have a high surface tension with water and cannot provide enough wetting for a good diffusion [19, 29, 38, 21]. The most common method for applying the sulfur coating is spray. Molten sulfur compound will be sprayed over a pre-polymer coated fertilizer granule [38,43]. 2.5.3. Wax-polymer coated There are lots of researches focusing on making controlled release fertilizers using Wax-polymer coatings. Wax layer has three major benefits; one is that they are applied over the polymer layer for decreasing the fracture probability of coating and the other one is for decreasing the amount of polymer and avoiding consuming more polymers to make the process cost effective. Also, they can eliminate imperfection of granules surface to make a good surface coating. Most common waxes which have been used in state of the art is C30 alpha-olefin and paraffin. Other petroleum products like lubricants and bitumen or natural products like canola oil, soybean oil, coconut oil and palm oil, also have been used. After melting the wax it will be applied by mixing with polymer coated fertilizer. Normally the polymer is thermoset to avoid any damages of polymer by the wax in its melting point. The wax normally should have drop melting point from 50 to 120 °C. Wax is normally about 0.2% to 10 % by weight of fertilizer [25, 38, 44, 45]. 2.5.4. Filler- polymer coated As mentioned before, despite lots of advantages of polymer coating to make slow release properties when such polymers are used as a sole coating material the ultimate product would be expensive as you have to consume large amount of polymer. Using mineral or organic fillers is one way to avoid using large amount of polymer. Also, in some researches fillers play the role of detackifier, to prevent adherence of coated granules to each other, and strengthening agent [46]. Fillers may be used either as a mixture with polymer to make a nano-composite polymer [47] or as a separate layer. The most common method is second one in which the filler will be added and mixed with polymer coated granules before drying the granules. Most common used fillers are some very fine(less than 20 microns) inert inorganic materials like clay, diatomaceous earth, bentonite, kaolin, gypsum powdered limestone, talc, barium sulfate. Some other fillers like waste cellulosic materials also have used as filler in combination with polymer.[47-51] 2.6. Techniques coating application According to studies have been done; encapsulation methods of fertilizers can be divided into three methods including in-situ, spray and mixing. 2.6.1. In situ This method includes formation of fluid dispersion of the soluble fertilizer in a solvent and mixing the prepared solution with monomers of a polymer. Polymerization will happen and depend on the method; granules or particles of fertilizers will form. Ni et al [52] have developed a double-coated urea fertilizer. For preparation of poly (N-vinyl-pyrrolidone) hydrogels containing urea (PCU), the monomer and a solution of urea in N-vinyl-pyrrolidone were mixed together. The polymerization was carried out at 65à ¢- ¦C for 3 h. The resulting samples were vacuum-dried, milled, screened and stored. After that first coating was dried sample and some amounts of urea were mixed with sodium alginate (SA) solution. Mixed solution was then added drop wise into 5% (w/w) CaCl2 aqueous solution and stirred constantly. The drops immediately turned into granules (about 4mm in diameter) because the SA in the drop was crosslinked by Ca2+ at once. The granules were filtered and dried in oven at 70à ¢- ¦ C. Then the granules were added to ethylcellulose ethanol solution. Multiple EC coatings were prepared by immersion of the previously coated granules into the Ethylcellulose (EC) solution repeatedly. Thus, EC-coated urea granules with different coating thickness were obtained. Hanafi et al [53], have coated a compound fertilizer by polyvinyl chloride (PVC), polyacrylamide (PA), natural rubber (NR), and polylactic acid (PLA) using in situ method. For encapsulation of compound fertilizer with polyacrylamide the granules were added to the solution mixture of monomers. Then the polymerization reaction will start in existence of fertilizers. The thickness of the coating layer on the compound fertilizer granules, determined by SEM, gave PVC compound coated fertilizer the highest value of 3.04 lm, and the lowest was obtained by PA (2.04  µm). Variation in the characteristics of the polymers would be utilized in producing CR compound fertilizer that fit the requirements of growing plants. Hudson et al [38] used epoxy to coat the fertilizer. In this research the urea granules were charged to a pan and warmed to 95 °C. Then the hydrogenated tallaw amine, 2-amino ethyl peperazine and bisphenol A diglycidyl ether were mixed and were added to the granules; meanwhile polymerization happened and prepared mixture was agitated till the fertilizer granules dried. 2.6.2. Spray method This method is most common method for coating the fertilizer granules in state of the art[. Usually, the solution of polymer in a suitable solvent is sprayed on the granule of fertilizer and then the granules are dried to remove the solvent through evaporation. The treatment is repeated as often as necessary until the desired coating percentage is reached. Lan et al [54] have used Chitosan and poly(acrylic acid-co-acrylamide) as biodegradable polymers to coat the NPK fertilizer. The NPK was compound fertilizer granules with about 2 mm in diameter. It was placed in a rotary drum and then the Chitson powder which was dissolved in epoxy-aceton solution was sprayed over the fertilizer. After drying the coating , Chitson coated granules were added to a flask equipped with a mechanical mixer. Carbon tetracholoride, polyethylene glycoloctyl phenyl ether, sorbite anhydride monostearic acid ester, solution of acrylic acid acrylamide , N,N- methylenebisacrylamide and ammonium persulfate was slowly added to the flask. After mixing the coated granules were dried in oven. This product with good controlled-release and water-retention capacity, being degradable in soil and environment-friendly, could be especially useful in agricultural and horticultural applications. Tomaszewska et al [55] have used spray technique for encapsulation of fertilizers. In order to improve the properties of coatings, the granules of previously coated fertilizer (wet method) were sprayed with a polymer solution or pure solvent (N,N dimethylformamide). Concentration of the polymer in solutions used for spraying was in the range of 13-17 wt%. Measurements of thickness, porosity of prepared coatings and microphotographic observation of the coatings were taken. Ma et al [56] have developed a method for encapsulation of fertilizer with a self assembled coating. The fertilizer granules were heated in a rotary drum to 75 °C for 10 minutes. Then the self assembling amphiphilic molecules (N,N-bisaminoethyl eleostearate) were sprayed over the fertilizer. After 20 minutes aliphatic isocyanates were sprayed over fertilizer. This process was repeated once again. The fertilizer kept for drying in the 75 °C for 20 minutes. Dai et al [57], have developed a controlled release fertilizer using a water soluble resin as a coating. The granular compound fertilizer was coated in fluidized bed. Lan et al [58], prepared a double-coated slow-release NPK compound fertilizer with superabsorbent and water-retention properties (DSFSW), whose inner coating was chitosan (CTS), and the outer coating was crosslinked poly(acrylic acid)/diatomite-containing urea (PAADU). This prepared product not only has slow-release property but also could absorb a large amount of water and preserve the soil moisture at the same time. In addition, the outer coating (PAADU) could protect the inner coating (CTS) from mechanical damage. These were significant advantages over the normal slow release or controlled-release fertilizers, which generally have only a slow-release property. The results indicated that the DSFSW could be found an application in agriculture and horticulture, especially in drought-prone regions where the availability of water is insufficient. At first the outer coating containing urea diatomite (PAADU) was prepared. The NPK compound fertilizer granule was placed into a rotary drum, and the Chitosan powder was stuck on the granules by means of epoxy dissolved in acetone. The adhesive was applied by spraying at regular time intervals. The process was finished until compact and homogeneous coating formed on fertilizer granule. The coated granules were dried to a constant mass at room temperature for 6 h. Then the CTS-coated NPK compound fertilizer granules were obtained. CTS-coated NPK compound fertilizer granules were dipped in water and then were immediately placed on PAADU powder and shaken. In this manner, PAADU could adhere to the surface of CTS-coated NPK compound fertilizer and form the outer coating. The surface of the product was crosslinked by spraying methanol solution of epoxy chloropropane and then dried in a 70  °C oven to obtain the final product, i.e., the double-coated slow-release NPK compound fertilizer with superabsorbent and water-retention. Hansen et al [36], encapsulate the granular fertilizer with the epoxy resin using spray method. In this research not coated fertilizer was placed in a rotating drum and pre heated to 250 ° F. A rapid drying solution of copolymers dicyclopentadiene and a modified vegetable oil were applied over fertilizer using spray in a thin stream of resin. Simultaneously hot air was passed through drum. Next monomers of second resin including a mixture of epoxidized soybean oil and polyester curing agent were applied over prepared granules. The solvent was a mixture of xylol and Cellosolve acetate. Hansen et al [39] also have used the above mentioned method for encapsulation of fertilizer with polyurethane. First of all the preheated fertilizer was coated by a synthetic drying oil. After drying the coating for a few minutes fertilizer were dusted by clay. Then Urethane solution in xylene and Cellosolve acetate were applied using spray. 2.6.3.Simple mixing In this method granules are simply mixed with the coating at its melting point or with a solution of polymer in a suitable solvent. Tomaszewska et al [59] used this method for coating the granular NPK fertilizer with polysulfone (PSF), cellulose acetate (CA) and polyacrylonitrile (PAN). The coating solutions were prepared by the dissolution of the solid polymer in adequate solvent. The NPK fertilizer was successively added to adequate polymer solution, and was covered by a thin layer of the solution. Subsequently, granules were dropped into water, where the gelation process takes place. The coated granules were removed from the precipitation bath and then dried to a constant mass. The multiple coatings were prepared by immersion of the single coated fertilizer into adequate polymer solution, then into water and drying. Hon [47] has prepared the coated granules by mixing method. After melting the thermoplastic polymer by heating, the cellulosic additive has been added to melt resin. Then after allowing the temperature to drop, for avoiding the fertilizer damage, the granules or powder fertilizer has been mixed with the prepared mixture using a Brabender Mixer. Markusch et al[60] just has mixed the fertilizer pellets with at first, a diluted polyol and then with a diluted isocyantae to make a polyurethane coating. Then the feretilizer were placed in oven for drying. 2.7. Special equipment for application of polymer coating Typical physical method for encapsulating fertilizers are spray coating, spray drying, pan coating, rotary disk atomization. Special equipments for these methods are rotary drum, pan or ribbon or paddle mixer, fluidized. Fluidized bed and rotary drums are the most important equipments [87, 88] Polymers used as coating for CRFs A broad range of polymers has been used in fertilizer coating. These polymers could be thermoset, thermoplastic or biodegradable. Some of common thermoset polymers are urethane resin, epoxy resin, alkyd resin, unsaturated polyester resin, phenol resin, urea resin, melamine resin, phenol resin, silicon resin. Among them, urethane resin urethane is very common used.[36,61] Thermoplastic resins are not very common used in art because of some problems. As mentioned before a very preferable method of applying polymers is spraying the dissolved polymer over granules. Either some of thermoplastic resins are not soluble in a solvent or make a very viscose solution which is not suitable for spraying. Polyolefine is used in art for coating the fertilizer granules [47,62]. Biopolymers, dispose in bioactive environments, degrade by the enzymatic action of microorganisms such as bacteria, fungi, and algae and their polymer chains may also be broken down by non enzymatic processes such as chemical hydrolysis. Non-biodegradable polymers are not environmental friendly. Due to environmental concerns there are some trends of replacing non-bio with bio degradable polymers as coating material from 1970s. But it should be mentioned that they are expensive yet and not very cost effective. Also, in production process durability of polymer should be adjusted with release time of fertilizer. Among natural and synthetic biopolymers starch and cellulose based polymers, chitosan (a linear  polysaccharide),poly lactic acid and poly(ÃŽÂ µ-caprolactone) due to low cost and abundance are some of used biopolymers in fertilizer industry[41,52,58,63-69] 2.5. Coating thickness Generally, polymer coatings are applied in a thickness which is suitable to make a desired controlled release property. Thickness could be related to characteristic of polymer and also it depends on existed porosity of polymer surface. If water vapor transmission rate of coating material is 0.01 to 20, coating thickness would be 1 to 100 microns. Preferred coating thickness is 1 to 50 microns. Coating process could be repeated more than one layer to get desired nutrient release [49]. 2.6. Investigation of release behavior of CRFs Release mechanism for different coatings is different. Thick encapsulated granules like sulfur coating will allow the nutrient to release when a flaw or rupture appears on the coating surface. In this case, rupture will happen because of permeation of water into coating and inside osmotic pressure. Also, biodegradable polymers will release nutrients while destroying by soil microbes activity. Polymer coatings or combination of different coatings will happen by diffusion of water through walls porosities. In this case release rate of can be controlled by the particle size of coated granules, thickness of coating and permeability of coating surface. Also, altering the chemical composition of fertilizer core and the coating will change permeability of coating; means that even basic or acidic environment will change the permeability. In some researches when the coating has been starch-vinyl, increasing size of encapsulated granules has led to slowing down the nutrient release [70, 71]. There are some standard test methods for measurement of controlled release properties. According To European standard the standard release time of N during 24 h should be 15% of total core nutrient. Also, release rate for 15 day should be 75% of total nutrients. Also American and Japanese standards say that the initial release shouldnt be more than 40% of total nutrient. According to European standards for measuring the release rate encapsulated fertilizer should be immersed in pure water at 25  °C (room temperature) in incubated state [72, 73]. For example Detrick et all[43] have investigated the release behavior of their product by immersion of 20 g of encapsulated granules for 8 h in water. After filtration of solid they dried the solid. Evaporation of water was done at 100  °C for 8 hours. Also, Ma et all [31] placed 14 g of granules in wire mesh holder into a jar with 300 ml water at 23  °C and agitated ir by an orbital shaker. Then, the adequate water was taken for elemental analysis.. Locquenghien et al [40] for investigation the slow release effect of fertilizer some amounts of fertilizer were continuously extracted with water. For this purpose the granules were arranged in layer in a cylindrical vessel field with water. Water was passed through this layer and its Nitrogen content was analyzed. 2.8. Commercial CRFs in world and Malaysia Urea-formaldehydes are oldest slow release products which were produced in 1936 and then were commercialized in 1970s. These products were known as Ureaform, Bluchip, Nitroform Methex and Nutralene. After that Tennessee Valley introduced sulfur coated urea technology in1960s.Polymer coated fertilizers were produced as early as 1970 in Japan. Most important commercialized polymer coated CRFs are Osmocote, Nutricote [74] Osmocote CRFs are NPK granules coated by a thermoset copolymer of dicyclopentadiene and a glycerol ester (linseed oil) dissolved in an aliphatic hydrocarbon solvent. The Osmocote CRFs are normally used for ornamental horticulture production like greenhouses, nurseries , citrus , and strawberry production[75]. Nutricote prills are encapsulated by thermoplastic resins likeas polyolefins, polyvinylidene chloride. The process of Nuricote involves dissolving polymer in fast-drying chlorinated hydrocarbon solvents and then applying the solution to a variety of nutrient substrates including urea, potassium sulfate, diammonium phosphate, ammonium nitrate and potassium chloride. Blendin the polymer with talc and ethylene-vinyl acetate has been done to obtain desired release rate[76] Sierra, Lesco and polyon are some other commercialaized CRFs in the world. In Malaysia two brands named Greenfeed[77] and KAMILA[78] has developed slow release fertilizer. Greenfeed contains Zeolite which helps to release nutrients when it is in contact with soil. KAMILA is specially formulated for oil plantation industry. 2.9. Tracing nano-technology features in fertilizer industry Reviewing literature shows that researches which have used nano-technology features in fertilizer industry are very rare. The main benefits of nanoparticles in these researches are using them as reservoir of fertilizer or as filler [79,80]. Solid nano-particles, have large surface areas and their reactivity is much more greater than that of micrometer size materials. Also, their surfaces and interfaces provide an active substrate for physical, chemical, and biological reactions [80]. Two published researches have done using nano-particles. One has used nano-clay as carrier of metal-urea complex; urea intercalated clay without any coating has been developed as slow release fertilizer[79]. In other one, a nanocomposite of nano particle, fertilizer and polymer has been granulated and developed as slow release fertilizer. The production method involves mixing monomers, adding nano particle, which could be nano clay, nano bentonite, nano kaolin, polymerization and then granulating the mixture. In this research nano particle just work as good and effective filler [81]. Making polymer-nano-particle composites is something common in industries. Lots of researches have been done in this area, but researches around using nano-particle as reservoir for fertilizer have been done rarely. For more study here, we will review the researches have been done. 2.9.1. Interc

Women Breaking Free From Their Traditional Expectations Essay -- essay

Women Breaking Free From Their Traditional Expectations   Ã‚  Ã‚  Ã‚  Ã‚  All throughout the early part of history women were portrayed as the inferior sex, because at that point in time, women were seen as beings only born to have children. Men didn’t think that women were capable of being anything other than a typical housewife. It was unthinkable that women would actually need an education, let alone earn a living, or become a leader. These ideas are revealed all throughout classical literature. Rarely was a woman seen as doing anything but being dominated by males in some form, whether she was a man’s submissive devoted wife, a sexual object, or a woman being punished for wanting her freedom. We finally begin to see women trying to break free from these traditional expectations and barriers through the lives of Janie Crawford in Their Eyes Were Watching God by Zora Neale Hurston, John’s wife in â€Å"The Yellow Wallpaper† by Charlotte Perkins Gilman, Louise Mallard in â€Å"The Story of an Hour† by Kate Chopin, and Songlian in Raise the Red Lantern by Su Tong.   Ã‚  Ã‚  Ã‚  Ã‚   Zora Neale Hurston in Their Eyes Were Watching God shows how the lives of American women changed in the early 20th century. Janie Crawford is an example of a woman in society who follows her dreams, takes control of her soul, and finds her own identity in a male dominated world. After two marriages in which Janie is ‘owned’ by the men in the relationship, she finds that she can own herself. â€Å"Janie was an unusual protagonist for her time—black, female, independent, and strong† (Shafer). Janie’s first effort to free her soul is from her husband Logan Killicks. Logan works her like a mule, making her do house chores as well as outside work. When she finally realizes that she doesn’t want to spend her life as a slave or with someone that she doesn’t love, Janie runs away to be with a man she had met only a few days before. Janie faces reality and gets out from under Logan’s rule before she becomes consumed into his world. Again Janie is only a possession of her new husband, Joe Starks. He displays her like a medal around his neck. He is so jealous of other men lusting after his wife that he restricts her to always tend the store, leave fun situations, and wear a head rag to hide her beautiful hair. Janie slowly breaks out of the shell that Starks has molded her into when she verbally defies him in front ... ...oper place was in the home. Even the laws and literary writings reflected this position. As women became more educated, they began to seek their freedom and a voice in society. This movement to gain equal rights for women has been referred to as feminism. Slowly have we made our way in history, but profoundly do we take our stand in life.   Ã‚  Ã‚  Ã‚  Ã‚   Works Cited Aull, Felice â€Å"The Yellow Wallpaper† The Feminist Press at the City Univ. of New York (New York) 1892 7 July 2000 http://mcip00.nyu.edu./lit-med/lit-med-db/webdocs/webdescrips/gilman87-des-.html Gribben, Alan. â€Å"Chopin, Kate† The World book Encyclopedia. 1990 ed.

Far from the madding crowd’ is set in the late 1860s to the early 1870s :: Free Essay Writer

Far from the madding crowd’ is set in the late 1860s to the early 1870s in Wessex, a fictional county based heavily on Dorset. Far From The Madding Crowd Thomas hardy was born in 1840 in Dorset which is located near Dorchester. Hardy's first important novel was Far from the Madding Crowd in which he successfully adapted to a traditional form to his own purposes, slightly changing it in the process. His novel states the importance of man's connection to, and understanding of, the natural world. The story is set in an agricultural rural community. He viewed the industrial revolution as a major threat to the communities he loved. The main character in this novel is a shepherd who is called Gabriel, this gives off a very pastoral mood in the novel. The plot develops complications when Bathsheba has love for three different men. Gabriel Oak who is the shepphard embodies Hardy's ideal of a life in harmony with the forces of the natural world. Throughout the entire novel there are unusual twists and turns and in the end Bathsheba ultimately marries Gabriel, whom she had turned away so long ago. In the story of all Thomas Hardy’s novels, both love and fate play major roles. In the first chapter we are introduced to Gabriel oak. He is a young sheppard. The main incident starts when Gabriel is walking in the countryside and he sees a wagon travelling down the road, and sees this young attractive woman is sitting on top if it. The Waggoner comes to a halt when they reached the gatekeeper and they had to pay a fee of three pence but the woman refused and only offered two pence. Gabriel stepped forward and paid the gatekeeper the rest of the fee and he insisted to let the women pass. ‘Far from the madding crowd’ is set in the late 1860s to the early 1870s in Wessex, a fictional county based heavily on Dorset. The village where Gabriel oak lives is in a small rural community. Many people such as Oak liked to hold onto their traditional views and values. Nowadays many of these views would be considered conservative and possibly outdated. Oak being a Shepard is very significant because it links back to the bible, so there are a lot of religious and biblical references in this novel. Most people went to church on Sunday. Church was very important. We learn that Gabriel Oak goes to church but doesn’t take it seriously. Hardy uses rural dialect to bring the minor characters to life, this gives them some personality. ‘Higgling matter’. Even though it is a winter’s day it is described as

Killing Is Never Justifies :: essays research papers

Killing Is Never Justified Capital punishment, by definition, is the legal killing of an individual. Now, how someone could be killed legally when murder is universally recognized as a violent and serious crime. It is irrevocable, meaning that once an inhabitant of death row pays the ultimate price. The death penalty is corporal punishment in its most severe form and is considered to be the ultimate form of retribution for those who have committed society's most heinous crimes, including rape and murder. Ultimately, Capital punishment is wrong due to the likelihood of error, the unjust racial allocation, and the violation of constitutional rights. However, many people believe that capital punishment is morally correct and preserves human dignity. Primarily, until human judgment is proved to be infallible, capital punishment will always carry a likelihood of error along with it. As Hugo Adam Bedau said in his writings, â€Å"Since 1900, in this country, there have been on the average of four cases per year in which an entirely innocent person was convicted of murder. Scores of these people have been sentenced to death† (Bedau 8). Considering that four completely innocent citizens had been sentenced to death, in a period of twenty years about eighty innocent people would have been wrongly sentenced to death. Human judgment and the justice system in which the United States of America is based on will never be perfect; there will always be a margin of error. Because of the infallibility of human nature, a few people each year are accused of crimes in which they did not even commit. Should innocent citizens be placed on death row and sentenced to death for crimes they did not commit? Because the justice system will never be perfect and mistakes are inevitably going to be made, capital punishment is not a just solution, especially for the innocent. Furthermore, many innocent convicts have been executed, while others have been lucky enough to prove their innocence in time. Subsequently, according to the Atlanta Weekly newspaper, In Georgia in 1975, Earl Charles was convicted of murder and sentenced to death. A surviving victim of the crime erroneously identified Charles as the gunman; her testimony was supported by a jail-house informant who claimed he heard Charles confess. Incontrovertible alibi evidence, showing that Charles was in Florida at the very time of the crime, eventually establishes his innocence–but not until he had spent more than three years under his death sentence.

Florence Nightingale

Abstract On her death in 1910, Florence Nightingale left a vast collection of reports, letters, notes and other written material. There are numerous publications that make use of this material, often highlighting Florence’s attitude to a particular issue. In this paper we gather a set of quotations and construct a dialogue with Florence Nightingale on the subject of statistics. Our dialogue draws attention to strong points of connection between Florence Nightingale’s use of statistics and modern evidence-based approaches to medicine and public health.We offer our dialogue as a memorable way to draw the attention of students to the key role of data-based evidence in medicine and in the conduct of public affairs. 1. Introduction 1. 1 Who Was Florence Nightingale? Florence Nightingale (1820 – 1910), hereafter referred to as FN, made remarkable use of her ninety years of life. She was the second of two daughters, born in England to wealthy and well-connected parents. There were varied religious influences. Her parents both came from a Unitarian religious tradition that emphasized â€Å"deeds, not creeds†.The family associated with the Church of England (Baly 1997b) when property that FN's father had inherited brought with it parochial duties. A further religious influence was her friendship with the Irish Sister Mary Clare Moore, the founding superior of the Roman Catholic Sisters of Mercy in Bermondsey, London. Her father supervised and took the major responsibility for his daughters’ education, which included classical and modern languages, history, and philosophy. When she was 20 he arranged, at FN’s insistence, tutoring in mathematics.These and other influences inculcated a strong sense of public duty, independence of mind, a fierce intellectual honesty, a radical and unconventional religious mysticism from which she found succour in her varied endeavours, and an unforgiving attitude both toward her own faults and towar d those of others. At the age of 32, frustrated by her life as a gentlewoman, she found herself a position as Superintendent of a hospital for sick governesses. Additionally she cooperated with Sidney Herbert, a family friend who was by now a Cabinet minister, in several surveys of hospitals, examining defects in the working conditions of nurses.On the basis of this and related experience she was chosen, in 1854, to head up a party of nurses who would work in the hospital in Scutari, nursing wounded soldiers from the newly declared Crimean war. Her energy and enthusiasm for her task, the publicity which the Times gave to her work, the high regard in which she was held by the soldiers, and a national appeal for a Nightingale fund that would be used to help establish training for nurses, all contributed to make FN a heroine.There was a huge drop in mortality, from 43% of the patients three months after she arrived in Scutari to 2% fourteen months later, that biographers have often att ributed to her work. Upon her return to England at the end of July 1856 FN become involved in a series of investigations that sought to establish the reason for the huge death rate during the first winter of the war in the Crimea. Theories on the immediate cause abounded; was it inadequate food, overwork, lack of shelter, or bad hygiene?In preparation for a promised Royal Commission, she worked over the relevant data with Dr William Farr, who had the title â€Å"Superintendent of the Statistical Department in the Registrar-General’s Office†. Farr’s analysis persuaded her that the worst affects had been in Scutari, where overcrowding had added to the effect of poor sanitation. Sewers had been blocked, and the camp around had been fouled with corpses and excrement, matters that were fixed before the following winter. The major problem had been specific to Scutari.FN did not have this information while she was in the Crimea. The data do however seem to have been re adily available; they were included in a report prepared by McNeill and Tulloch (1855). The strain of FN’svarious involvements, and perhaps residual effects from an illness that she had suffered while in the Crimea, in due course took their toll. A year after her return to England, she suffered a nervous breakdown, emerging from this personal crisis with views that were often remarkably different from those that she had held earlier.Of particular interest is a change from her demand that nurses should follow to the letter instructions from doctors, to her view that nurses ought, within their proper area of responsibility, to make their own autonomous judgments. Small (1998, pp. 119 – 127, 178) has extensive and perhaps overly speculative comment on the reasons for the nervous breakdown, and an interesting analysis of ways in which her views changed. The data that showed that the high mortality was specific to Scutari were included in FN’s 1858 report, but omitte d from the 1857-1858 Royal Commission report.It was feared that continuing and acrimonious attempts to assign blame would jeopardise ongoing efforts at army reform. FN, unhappy at this suppression of her evidence, sent copies of her report to a number of carefully chosen recipients, each time with instructions to keep it confidential. One of the recipients was the freethinking popular journalist Harriet Martineau. With FN’s help, she wrote a book (Martinueau 1859), ostensibly based on information from public documents but using FN’s confidential report for additional background information, that gave the facts as FN understood them.FN’s biographers, perhaps relying too much on official documents, have not until recently been mindful of these nuances. See Small (1998, p. 198 – 200) for further discussion is one of the first to recognise them. A comprehensive biography of FN, that will do justice to the wide-ranging sympathies and interests of this remarkab le woman and show how her views changed and developed over time, has yet to be written. Small (see the note on his web site) and Baly (1997b, pp. 1-19) both draw attention to inaccuracies in earlier biographical accounts.Vicinus and Nergaard (1989) have much carefully documented biographical information. Among the numerous web sites that have material on FN note C. J. McDonald (2001) who emphasises connections between Nightingale and the experiences of soldiers in the Vietnam War; L. McDonald (2002) who is leading a project to publish all Nightingale’s writings; and Small (1998). Small’s web site has the data (from Nightingale 1858) that the Royal Commission suppressed. 1. 2 Hospitals and Hospital Nursing FN had remarkably radical views on hospitals and on hospital nursing. Both in 860 and in 1876, she describes hospitals (Baly 1997b, p. 25; Nightingale 1876) â€Å"as an intermediate stage of civilisation. † In 1867 she wrote (Baly 1997b, p. 21) â€Å"my view y ou know is that the ultimate destination is the nursing of the sick in their own homes. †¦ I look to the abolition of all hospitals and workhouse infirmaries. But it is no use to talk about the year 2000. † Consistent with these views, FN’s Notes on Nursing (1859) are not intended â€Å"as a manual to teach nurses to nurse†, but are â€Å"meant simply to give hints for thought to women who have personal charge of the health of others. It may thus seem ironic that, in her work with the Nightingale fund, FN was deeply involved in the development of hospital nursing training. She opposed the British Nurses’ Association’s 1890 proposals to make nursing into an accredited profession (Baly 1997b, pp. 184-196). She noted that there was no widespread agreement on what constituted an adequate training or what the minimum qualification should be, and argued that a much longer experience was needed before a register could be contemplated. The qualities t hat were required in nurses were not amenable to test by public examination.FN did however see an important role for women medical professionals. She wanted women to take leading roles in midwifery and in the diseases of women and children, and to be as well or better trained for these tasks as the men who at that time had a professional monopoly. It was her view that â€Å"There is a better thing than making women into medical men, and that is making them into medical women† (Nightingale 1871). She looked to a time when, as had happened in France, women would be professors of midwifery.She set out the immediate steps that she thought would best achieve that end. FN worked relentlessly for reform, in the army, in the hospitals, and in public health. She was meticulous in researching the reforms that she proposed. Where, as often, data were unavailable or inadequate, she pressed for their collection. Data inadequacies are strong themes in her Notes on Hospitals and in her Intr oductory Notes on Lying-In Institutions, i. e. , on maternity institutions. She made strong, consistent and carefully argued cases for enlightened and data-based public decision-making.This is not to say that FN was always correct in her judgments. In her next to final contribution to the dialogue, FN comments on a controversy that erupted following the publication of the third edition of her Notes on Hospitals. Her use of the term mortality percent for deaths per hundred beds per day, which she copied from Farr's report as Registrar-General, was unfortunate. As she seems to admit a page later in the Notes, these figures were not a good basis for comparing the sanitary states of different hospitals. Florence Nightingale I was really moved when Dr. Howe advised Florence that â€Å"If you have a passion, the only way to satisfy it is to pursue it. † Yes, you will only be satisfied in your life when you pursue your passion on something because if not, you will only regret it and in the end you weren’t able to help other people as well as yourself. Florence really did not neglect God’s call to her and this really demonstrated the passionate side of her. Thanks to Dr. Howe, she found out that nursing is really her calling. I also admired Florence’s determination when she rejected Mr. Milnes and preferred to concentrate on her career. For me, to have a passion the same as her, marriage would really interfere with her ability to follow her calling. This is because it would really be difficult for Florence to manage a family when she is definitely drawn into helping other people. Florence is a good leader because she is understanding to the other nurses and all of them will really follow her orders. She is smart and knowledgeable in the proper health care. Florence has that â€Å"magic† in healing and also she has a strong persona when she is dealing with dying patients. Furthermore, who knew how much prejudice there was against nurses before? It was really a terrible prejudice, considering nurses as little more than â€Å"hangers-on† and the prejudice in the army was shocking. The head doctors would prefer to see soldiers die than let the nurses trained by Florence work in the military hospitals. Compared to nowadays, nurses are really respected and honoured because of the love and care they give to their patients. It is good to be reminded of the damages prejudice can cause and just how powerful it is as a social force The film was outstanding for me. The portrayal and the flow of the story were good. Jaclyn Smith was very good as Florence Nightingale. And the film really showed the complete detail of Florence Nightingale’s works in the field of nursing.
