The Pulmonary Function Tests Health And Social Care Essay

Development of our state has lead to rapid urbanisation and there is addition usage of cars that is worsening environmental pollution. Occupational exposure to automobile fumes and industrial fumes has been shown to impact operation of different systems of the organic structure. The present survey was taken up to measure the Pulmonary Function Tests ( PFT ) in car jinrikisha drivers of Gulbarga metropolis. Methods: Fifty non -smoker male car drivers in the age group of 20-50 old ages for more than 5 old ages of car driving experience formed the survey group. Age and sex matched persons non exposed to car rickshaw driving [ administrative staff ] formed the control group. Pulmonary map parametric quantities FVC, FEV1, FEV1 % , PEFR, PIFR, FEF25-75, FEF50 and MVV were assessed utilizing computerized Spiro metre during their on the job hours and were statistically analyzed. Consequences: There was a extremely important lessening in FVC and FEV1 in survey group compared to command group. The lessening in FEV1 % , PIFR, FEF25-75 and FEF50 were statistically important but the lessening in PEFR and MVV were statistically non-significant. Decision: Our findings point towards the inauspicious effects of vehicle fumes on lung maps, chiefly on lower air passages with restrictive form of disease. Keywords: Cars, Auto drivers, Pulmonary maps trials.IntroductionNumerous epidemiological surveies have documented decreases in pneumonic map and assorted other wellness jobs associated with long term air pollution exposure1.Health effects of occupational exposure to crude oil bluess and air pollution from vehicular beginnings is comparatively undiscovered among car jinrikisha drivers. To run into the present twenty-four hours demand, there is an addition car usage and because of the prevailing function of gasolene [ gasoline ] as a motor vehicle fuel, the effects of gasolene engine emanations are potentially even greater jobs. In the individuals exposed to these pollutants, pneumonic map trials are used as testing trials to find their effects2.Therefore, the present survey is taken up to measure the alterations in Pulmonary Function Tests ( PFTs ) like Forced Vital Capacity ( FVC ) , Forced Expiratory Volume in the first second ( FEV1 ) , FEV1/FVC ratio, Peak Expiratory Flow Rate ( PEFR ) , Peak Inspiratory Flow Rate ( PIFR ) , Forced Expiratory Flow in 25-75 % of critical capacity ( FEF25-75 ) , Forced Expiratory Flow at 50 % of critical capacity ( FEF50 ) and Maximum Voluntary Ventilation ( MVV ) of car jinrikisha drivers in Gulbarga metropolis.Materials & A ; Methods:The present survey was conducted in Salgar infirmary of Gulbarga metropolis. Ethical clearance was taken from the Institutional Ethical Committee and each topic gave the consent. The survey group consisted of 50 males in the age group of 20-50 twelvemonth, who were driving car jinrikisha for 8 hours per twenty-four hours for more than 5 old ages in Gulbarga metropolis. The control group consisted of 50 males of same age group from administrative station, who were non exposed to car jinrikisha drive. The topics chosen in the survey and the control group had no history of allergic upsets, respiratory upsets like asthma, or any systemic disease, no history of smoke, masticating baccy and consumption of intoxicant. Age, tallness, and weight were recorded. All the Pulmonary maps were tested during twenty-four hours clip utilizing computerized Spiro metre [ MEDSPIROR ] .The topics were familiarized with the instrument. All the trials were carried out at the same clip of the twenty-four hours, between 10-11 AM. All the topics were in sitting place and have oning nose clips3. The topics were asked to take a breath forcefully following deep inspiration into the mouthpiece attached to the pneumatachometer. 3 trails of maximum Inspiratory and expiratory attempts were made and the best reading was taken for statistical analysis. Statistical method used in our survey was pupil ‘s odd T trial utilizing SPSS-16. The P & lt ; 0.05 was considered statistically important and P & lt ; 0.001 was considered extremely statistically important.Consequences:The average value of the ages of the topics was 36.4AÂ ±7.40 and that the average value of the controls was 34.8AÂ ±3.76. The average value of the highs of the topics was 170.40 AÂ ± 3.39 and the average value of the controls was 174.60 AÂ ± 4.15 and the average value of the weights of the topics was 72.60 AÂ ± 7.56 and that of the controls was 74.40 AÂ ± 8.24. The topics and controls did non differ significantly on above parametric quantities.

The acute wellness hazards involved are minimum, provided that the precautional methods are used in conformity with appropriate wellness and safety patterns. Highly statistically important lessening in FVC and FEV1 was observed in car drivers when compared to their controls, and their ratio ( FEV1 % ) was important between the two groups. This determination indicates the restrictive form of pneumonic engagement in the survey group. Auto jinrikisha drivers are at hazard of dust inspiration, gasoline vapour inspiration and besides inspiration of car fumes for a longer period of clip that is at least 8 hours per twenty-four hours for more than one twelvemonth and they have more opportunities of chronic engagement of lungs as indicated by the consequences in the present survey. The benzine content of gasoline has typically been in the scope 1-5 % may be an aggravating factor for the lung map abnormalcies observed as the survey groups were nonsmokers. Smoking as an independent variable was found to impact FEV1 significantly and smoke has shown to speed up the diminution in lung map in a clip dependent manner4. As the car drivers are most of th e clip on busy roads and exposed to automobile fumes and other air pollutants. Automobile fumes is a complex mixture of different gases like Sculpture dioxide ( SO2 ) , Carbon dioxide, Carbon monoxide ( CO ) , Nitrogen dioxide ( NO2 ) and particulate affair. Some surveies have demonstrated that exposure to particulate affair combined with exposure to an irritant gas such as NO2 consequences in greater harm to the lung than when exposed to either substances individually5.In combination with particulate pollutants, SO2 and NO2 have a greater opportunity to make the deeper parts of the lungs. The gaseous pollutants may besides change the belongingss and concentration of surfactant and contribute to the early closing of little air passages. Much of the terminal bronchioles may be compromised before other pneumonic map trials such as FEV1 are affected6. Few histopathological surveies have provided grounds that the little air passages are the site of harm in people populating in countries of high air pollution7. Atoms generated from Diesel fumes are highly little and are present in the karyon or accretion manners with diameter of 0.02 am and 0.2 am severally. These little sized atoms, by virtuousness of their greater surface country to mass ratio, can transport a much larger fraction of toxic compounds, such as hydrocarbons and metals on their surface. Importantly they can stay airborne for long periods of clip and acquire deposited in greater Numberss and deeper into the lungs than big sized atoms. Hence chronic exposure to them can take to chronic redness of respiratory piece of land and lung parenchyma. These would lend to the significant lessening in lung maps in the signifier of restrictive form as indicated in the present survey. Rajkumar studied the consequence of air pollution on respiratory system of car jinrikisha drivers i n Delhi. The survey found that ( 19 % ) drivers showed normal Pulmonary Function Test ( PFT ) . ( 80 % ) showed mild and moderate to terrible obstructor, of which ( 48 % ) were non-smokers and ( 52 % ) were tobacco users and the consequence concludes that car jinrikisha drivers have a high respiratory morbidity due to exposure to pollution.8 In a survey, reduced mechanical belongingss of take a breathing were attributed to exposure to benzene in the bluess of petrol9. Bijendra Kumar et Al examined the pneumonic map trial in three Wheeler Diesel cab drivers in Bikaner metropolis. They found restrictive damage in 87 % of survey group, of which 50 % were tobacco users and 37 % were non-smokers, assorted form ( both restrictive and early clogging damage ) was found in merely 13 % of survey group, of which 7 % were tobacco users and 5 % non-smoker. So they concluded that when all the five parametric quantities ( FVC, FEV1, FEV1/FVC, FEF 25-75 % and PEFR ) were taken together they were de clarative of assorted form ( clogging and restrictive ) lung impairments10. Chattopadhyay et al conducted a survey on garage workers, drivers and music directors of Kolkata metropolis to measure the pneumonic map position of these workers and found that FEV1, FEV1 % and flow rates, FEF 02-121, FEF25 % -75 % values showed gradual decrease as age and continuance of exposure increased11.From the present survey it was concluded that respiratory maps of car jinrikisha drivers who are continuously exposed to emanations from vehicles, gasoline vapour and dust were significantly reduced as compared to respiratory maps of age, weight and tallness matched control groups.Recommendation:To forestall the respiratory disfunction among car drivers, medical observation and periodic check-ups for pneumonic map trials should be performed. Control schemes should be adopted to cut down the vapour concentration in the air, like vapour adsorbents and to cut down the benzine concentration in the ambient a ir. Personal protective equipment must be worn by car jinrikisha drivers. Imparting wellness instruction to car jinrikisha drivers will forestall respiratory morbidity. Further long term position surveies on car jinrikisha drivers will assist in acquiring a comprehensive image of long term effects.Recognition:This research paper is made possible by the support from the participants of our survey. We dedicate our recognition of gratitude towards Mr.Shaik.Meera and Dr. Rashmi.C.G as they kindly read our paper and offered valuable elaborate advices on grammar, organisation, and subject of the paper. Finally, we unfeignedly thank Godhead, household and friends, who provided fiscal support and timely advice.

Examine how Valvular heart valve disease has caused a major problem worldwide Introduction: Examine how Valvular heart valve disease has caused a major problem worldwide Introduction:Definition:Cellular sources:Biomaterials:Sterilization methods:Pre-clinical trials:Biomechanical culture:Commercialized products:Challenges:Conclusion:REFERENCES:Related Introduction: Valvular heart valve disease caused a major problem worldwide, result in increasing rate of morbidity and mortality (Rashid et al., 2004). Each of the four valves of heart can be affected by dysfunction (Mol et al., 2009). The common solution is the replacement of diseased valves either mechanical or bioprostheses. However, they are associated with shortcoming. Patients with mechanical valves are associated with long term of anticoagulation therapy which leads in higher risk of complications (Hjortnaes et al., 2009).   Bioprosthetic valves are less durable, enable to grow and repair and lead to calcification. Moreover, they are associated with reoperation especially with young patients. None of these valves are capable to restore native valves functions.   To overcome replacement shortage of heart valve, in the mid of 1980s in the USA, tissue engineering concept was proposed as alternative solution and has the capability to produce autologous heart valves (Matsumura, 2003). Definition: Tissue engineering of heart valves is manipulation of biological molecules and cells for the purpose of creating new structures capable of metabolic activity. (Vesely, 2005). Approaches: Worldwide, two main approaches have been used to achieve the desirable and clinical needs of heart valves; regeneration and repopulation (Vesely, 2005). In the first approach, decellularized xenograft (ECM proteins; collagen or fibrin) or allograft served as valve biological scaffold, mixed with autologous cells (myofibroblast and endothelial) has been seeded in vitro (Mendelson and Schoen, 2006), (Neuenschwander, 2004). However, limitations of this approach are; the construct lack the ability to grow, long term mechanical properties could alter physical properties of the native valves and a possibility of disease transmission (Neuenschwander, 2004). Moreover, inflammatory reaction due to ECM proteins used may deteriorate the scaffold result in biomechanical damage (Mendelson and Schoen, 2006). A biodegradable synthetic scaffold is the traditional approach in which cells of a specific phenotype are transplanted onto a bioresorbable scaffold in the shape of heart valves (Vesely, 2005).These biocompatible materials offer several advantages; Due to degradation products, they have neither side effects nor immunogenic reactions.   They are harmless and easy to handle. At the site of implantation, the remaining autologous living structures after complete biodegradation of the scaffolds have the ability to remodel, to adapt and to grow (Neuenschwander, 2004). The danger of the transmission of new infections and immunogenic reactions is minor as a result of utilization of autologous cells which lead to identical bioengineered tissues to host cells (Neuenschwander, 2004). Extracellular matrix material is formed by the cells after attachment and the polymer scaffold degrades (Fuchs et al., 2001). As shown in (Shinoka et al., 1995) mixed cell population of endothelial cells and from ovine arteries were isolated and separated from each other by fluorescence-activated cell sorting. An acetylated low-density lipoprotein marker was used to label endothelial cells. Myofibroblasts were seeded onto polyglycolic acid scaffolds which then seeded with endothelial cells. Before new tissues being regenerated, the degrading scaffold cannot tolerate pressures of the left ventricle (Vesely, 2005). Therefore, the constructs were implanted in sheep in place of the native right posterior leaflet of the pulmonary valve.   This approach results in trivial pulmonary regurgitation in autografts but moderate in allografts and doesn’t show stenosis (Shinoka et al., 1995). Repopulation is the less popular approach. Complex structure (collagen) is fabricated by manipulating biological molecules.   Prior to implanting, cleaning off the porcine aortic valve from cells is required, and leaving intact the connective tissue matrix. Then, the acellular matrix of the patients cells is repopulated, stimulated and thus result in creating a living tissue resemble to the native tissue (Vesely, 2005). Cellular sources: In tissue engineered valve applications, mesenchymal stem cells and differentiated tissue-specific cells (including circulating endothelial progenitor cells or smooth muscle cells) are the two main types used. They are harvested from either patients or experimental animals (Vesely, 2005). Stem cells along with the appropriate matrix are expected to provide a broader source of either autologous or allogenic cell lines once differentiated to the proper end point. Thus, they are beneficial for therapeutic use in the cardiovascular field (Vesely, 2005). Animals’ tissues such as canine and pigs are conducting in a research with variability in successful implantation.   Mesenchymal stem cells for TE of ECM scaffolds have been obtained from canine tissues. Also, due to presence of type 1 and IV collagen and fibronectin, ECM from pig’s tissues showed ability to grow to a single layer (Rashid et al., 2004). In most approaches, veins (saphenous vein) or peripheral arteries (radial artery, mammary artery) are efficient sources of cells. Mixed vascular cell populations give rise to myofibroblast and endothelial cells lines. myofibroplasts derived from arteries show decreased proliferation in monolayer culture and ECM formation when cultivated on three dimensional structure compared to cells obtained from veins (Neuenschwander, 2004). Another promising alternative source of heart valves can be derived from progenitor cells derived from peripheral blood and bone marrow cells (mesenchymal stem cells). MSC can be differentiated into different tissues, are easy to obtain, shows high proliferating capacity in vitro and faster growing than vascular derived cells. They produce well developed ECM after cultivation under bio-mimetic conditions (Neuenschwander, 2004). Biomaterials: There are two principal choices of scaffold; naturally or synthetic polymeric scaffolds. Exogenous ECM scaffolds are required to provide mechanical support until the target newly tissue is formed and become stable. Designing is based on the target cells population needed to implant at the injury or diseased sites. In vivo, they are degraded alongside the implanted functionally tissues grow and organize their matrix structure (Kim et al., 2010). Non-toxic, biodegradable and biocompatible scaffolds serve as a temporary matrix for the seeded cells due to their own a highly porous microstructure that supply nutrients required for growth and necessary for waste removal. They possess structural integrity to withstand in vitro and in vivo loading. The most widely used in HVE are polyglycolic acid (PGA), polylactic acid (PLA) and their copolymers (PGLA). PGA is highly resorbable, linear, a highly crystalline and have a high melting point. PLA reduce the rate of hydrolysis and have limited water uptake. In all of that, to facilitate tissue growth, growth factors are integrated in the scaffold. However, a number of disadvantages must be overcome; slow or incomplete degradation that cause inflammation, limited nutrients and oxygen delivery to deep cells and fibrosis (scar) occupied the space formed after scaffold degradation (Mendelson and Schoen, 2006). Natural scaffold composed of decellularized xenograft or allograft tissue or ECM components such as collagen or fibrin (Mendelson and Schoen, 2006). Fibrin gel scaffold can be designed into a valve structure to form a biodegradable, autologous scaffold.   Blood is the source of fibrin gel and mould into autologous manner to work against immunogenicity. Seeding cells into fibrin scaffold results in good tissue development with viable fibroblast. However, fibrin scaffold would lack mechanical strength (Knight, 2004). Furthermore, in a process similar to the contraction of a wound healing, cells entrapped in collagen gels compact the gel, improve their property and increase density (Mendelson and Schoen, 2006). But, any scaffold made from collagen alone would like to degenerate very quickly due to in vivo forces affected heart valves (Knight, 2004). Moreover, hyaluronan is a glycosaminoglycan polymer with a repeating disaccharide structure and being used as biocompatible material ECM scaffold. It imparts viscoelastic properties and applies pressure that gives tissues compressive resistance (Vesely, 2005). Sterilization methods: Several methods are used to sterile materials utilized in process of seeding and tissue harvesting. 1) Dry heat sterilization in which items are placed in an oven for one hour at 160T to be sterilized by dry heat. 2) Moist heat sterilization is used to autoclave objects and solutions not suitable for dry heat sterilization for 20 minutes at 121 T, 15 pounds per square inch (psi). 3) 0.2ptm filters are used to sterilize solutions not suitable for autoclaving (Knight, 2004). Pre-clinical trials: Animal model is an essential part of biomedical research to approve tissue engineered devices by FDA in order to carry on clinical trials. Using animal tissues as sources relies on many factors; cost, ethical considerations, availability and the nature of the tested tissue. In Zilla study (Zilla et al., 1994), baboons were used to study the proliferation of seeding (endothelial cells) EC on polytetrafluoroethylene (PTFE) grafts. Compared to the control of unseeded graft, seeded graft showed persistent confluent EC layer through time with the aid of fibrin glue enriched with RGD (Zilla et al., 1994). Due to similar anatomy and physiology to that of humans, pigs have been used widely for experimental study. Also, they are cooperative without general anesthesia. They are capable of rabid growth so limiting the time required for TE construct (Rashid et al., 2004). Biodegradable polyglycolic acid (PGA) scaffold was treated by sodium hydroxide and modified seeded bovine SMC and EC were used by Niklason and co-workers in after 24 days of implantation in swine model. Ovine and caprine are also models to study TE due to large size and easy access to the carotid artery in the long neck. They can be used for long term study because adult animal can’t grow (Rashid et al., 2004). In a number of researches, sheep model was used widely but ordained for failure as a result of exuberant fibrotic response to implants (Vesely, 2005). Compared to humans, implants grow rapidly with fibrotic tissue in sheep (Schoen, 2011). In preclinical testing, the choice of animal model is a challenge owing to immunologic considerations (Mendelson and Schoen, 2006). Biomechanical culture: Various parameters determine the optimal conditioning protocols; the scaffold, the magnitude and types of mechanical cues, the sensitivity of cell to the used scaffolds. Bioreactors in TEHV have been developed to improve tissue formation, organization and functions and to stimulate dynamic mechanical of the TEHV. Moreover, to mimic native excitation-contraction coupling, electrical stimulation has been used. Additionally, to mimic the diastolic phase of the cardiac cycle, a diastolic pulse duplicator bioreactor has been developed which result in dynamic tissue straining (Sacks et al., 2009). Commercialized products: In October 2000, CE Mark approved use of the CryoLife Synergraft. It was similar to decellularization matrix approach by removing cellular antigens using extraction and dissolution. It was expected to sound mechanically as acellular matrix. Unfortunately, complications related to stenosis, inflammation and valve rupture result in death and thus withdrew from the market (Vesely, 2005). Challenges: Till date, no EHV constructs have been commercialized. Before translation of the construct to patients, numerous steps must be considered and assured laboratory.   For example; ethical issues, safety, efficacy and quality of the product should be evaluated. Additionally, medical devices interactions results such as; thrombosis, infection and inflammation will have to be accepted. There is a need to develop tools to monitor the fate of transplanted and endogenous cells, biomarkers to evaluate the patients variability to implantation. in all of that, suitable approach is required that ensure efficiency and safety (Schoen, 2011). Conclusion: Three main issues determine the success of tissue engineered heart valve; 1) sources of cells, 2) the (matrix) scaffold that serves as a guiding structure and determines the three dimensional shapes of tissue development and cell attachment and 3) the optimal culturing condition for cell growth. State of art of TEHV today is still on research, significant challenges must be solved before start in clinical application. REFERENCES: FUCHS, J. R., NASSERI, B. A. VACANTI, J. P. 2001.

Interracial Adoption and Diverse Family Units †African American Studies

Interracial Adoption and Diverse Family Units – African American Studies Free Online Research Papers Interracial Adoption and Diverse Family Units African American Studies Adoption laws differ from state to state and even from country to country but one thing that remains is the benefits, happiness and joy it brings to families and children. The practice of adoption dates back at least as far as the 18th century BC, but it wasn’t always a good experience as children were sold into black market. It wasn’t until Hammurabi, who took the corruption out of the process, wrote the first legal reference about adoption. After WWII, organizations attempted to place children within families of other ethnicities and designed programs such as â€Å"Operation Brown Baby†. During the civil rights movement, interracial adoption began to radically multiply. The family experience is more important than growing up in a same-race environment; orphaned children are better off received care and love from a family unit, regardless of skin color. Throughout the decades, prejudice and racism has plagued this country by encompassing the minds of the each generation’s youth. Not until recently has people’s ideologies truly changed to begin accepting other cultures and the notion of interracial families. The Howard M. Metzenbaum Multiethnic Placement Act was instituted in 1994 which â€Å"prohibits an agency that receives Federal assistance and is involved in foster care and adoptive placements from delaying or denying the placement of a child based on race, color, or national origin of the child or adoptive foster parent or the child involved†(Wikipedia). In order to remove ambiguous language and any latent discrimination, this act was revised. The Interethnic Adoption Provisions, â€Å"forbid agencies from delaying or denying the placement of a child solely on the basis of race and national origin† (Wikipedia). There are many pros and cons of adopting interracially, however this development provides more benefits than harm. Although it may be challenging for a child to learn their culture with a family who does not share the same background, many believe that these children are still able to grow up as healthy individuals. Same race adoption is falsely considered to make most sense, and to inflict the least disruption in a child’s life. However, by practicing only race-matching adoption, minority children are left in the system to wait; most never getting adopted. â€Å"Minority children made up 60% of those in foster care nationwide in 1994 and waited twice as long for permanent homes as did other foster children (www.gao.gov).† The longer children are in the foster care system, the less chance they have of leaving. When they age out of foster care, â€Å"27% of males and 10% of females were incarcerated within twelve to eighteen months. 50% of these children were unemp loyed and 37% had not finished high school†. (Adoption.com). The statistics show that it is crucial to provide these children with support and encouragement as they grow older and it would be a crime to deny them this merely because of skin their color. Even if such issues such as culture and identity arise, the family can contribute to helping the child learn about it. Tips for raising a child of a different background include: Become intensely invested in parenting; Tolerate no racially or ethnically biased remarks; Surround yourselves with supportive family and friends; Celebrate all cultures; Talk about race and culture; Expose your child to a variety of experiences so that he or she develops physical and intellectual skills that build self-esteem; and take your child to places where most of the people present are from his or her race or ethnic group (Adoption.com). You should not allow your children to practice racially biased comments or others in your family network. By showing that it is unacceptable you are setting a boundary for your children. If you have a Hispanic child, take them to the Hispanic fair in your town. If you have a black child, buy her a black doll. Show that all cultures are unique, special, and should be celebrated and appreciated. Through discussion of other races and cultures, the child’s background will be rich in culture and diversity. Just by using some of these ideas, you can make having an interracial child a rewarding experience. There are an abundance of horrifying stories in which children are neglected and abused in the foster care system and even in their own homes with their biological families. Two-year old Brianna Blackmond was shuffled back and forth between foster care and her neglectful biological mother. On December 22, 1999, the judge handling Briannas custody case ordered the District of Columbia Child and Family Services to return her to her mothers home. There Brianna lived with her mother, her godmother, and twelve other children in a rat-infested, feces-stained home where the children went without food for days at a time. Two weeks later, Brianna died. Her godmother had beaten her with a belt and struck fatal blows to her head. (Swize) Placing a child in a home based on the biological and or ethnic similarities just reflects a self serving interest. It reflects society’s agenda to control the fate of economically disadvantaged children. Brianna’s fate is shared with many others who have suffered as the result of a system that cares more about the color of their skin then their quality of life. Regardless of the ethnic similarities a child and parent have in common, this does not mean they are more capable of providing a nurturing environment than a person of a different ethnicity. How can anyone place cultural awareness over a child’s physical well being? The fact that Child and Family Services placed Brianna back into the custody of a parent who had a history of being unable to provide for her is a disgrace. The very agency that is supposed to ensure the safety of millions of children in the system issues death warrants every time they carelessly return or place a child into unsuitable c onditions. The first time Brianna was removed from her biological mother’s home she was placed in a foster home with parents that were not black. The judge in her case openly stated that â€Å"the destruction of the black family (through trans-racial adoption) was driving her crazy†. This statement reflects the misguided focus and perception of those responsible for the placement of these children. It is obvious that they were anxious to take return her to an â€Å"unfit† mother for the sake of saving the â€Å"black family†. Situations like Brianna’s reveal the contradictions in the debate over trans-racial adoption. Kids are discarded to be victims of the system. The reality is there are not enough black families to meet the staggering numbers of foster children who need parents. Why would one deny them access to a better life based on the color of their skin? The standard that determines a child’s fate should be based on the love and support a family is able to provide not the superficial image of what a family should look like. ` People misconstrue the notion of interracial adoption as trying to obtain a color-blind society and erase the effects of past discrimination which society views as impossible. But this is truly not the case at all. The emotional and physical effects of growing up in the foster care system are far more traumatic than being raised in a trans-racial yet supportive family. Interracial adoption is not aiming at solving societal issues of prejudice but rather to benefit the quality of life of our children. This type environment encourages constructive exposure and identity to one’s race. Parents who have adopted children of another race may embrace their child’s culture and background by choosing to live in a more racially diverse neighborhood to ensure that their child is regularly exposed to families of the same race. As with any life experience, obstacles will be encountered when adopting a child of a different background but there are ways that you may overcome these. With the amount of minority children in foster care, and the people who have the means of adopting, we should not place a limit. Statistics show that interracial adoption is becoming more common place and it is worse to leave these children in the foster care system rather than placing them in an adoptive home regardless of race. There are ways to integrate an interracial family together and to ensure that the child will not lose their racial identity. An attempt to incorporate a color-blind society in today’s world is not what interracial adoption is trying to accomplish. The only concern is for the welfare of the flood of children in the foster care system and not to solve deep rooted societal issues. It is imperative to keep an open mind on this topic in order to facilitate the excessive and unnecessary amounts of ch ildren in foster care. The importance lies with providing these children with stable, healthy homes so they will be given a fair opportunity to live a mindfully healthy and happy life. 1. adoption.com.

The Saxons Were a Germanic People

The Saxons Were a Germanic People The Saxons were an early Germanic tribe that would play a significant role in both post-Roman Britain and early medieval Europe. From the first few centuries B.C. up until about 800 C.E., the Saxons occupied parts of northern Europe, with many of them settling along the Baltic coast. When the Roman Empire went into its long decline in the third and fourth centuries C.E., Saxon pirates took advantage of the reduced power of the Roman military and navy and made frequent raids along the coasts of the Baltic and the North Sea. Expansion Across Europe In the fifth century C.E., Saxons began to expand fairly rapidly throughout present-day Germany and into present-day France and Britain. Saxon migrants were numerous and dynamic in England, establishing along with several other Germanic tribes settlements and power bases in territory that until recently (c. 410 C.E.) had been under Roman control. Saxons and other Germans displaced many Celtic and Romano-British peoples, who moved westward into Wales or crossed the sea back to France, settling in Brittany. Among the other migrating Germanic peoples were Jutes, Frisians, and Angles; it is the combination of Angle and Saxon that gives us the term Anglo-Saxon for the culture that developed, over the course of a few centuries, in Post-Roman Britain. The Saxons and Charlemagne Not all Saxons left Europe for Britain. Thriving, dynamic Saxon tribes remained in Europe, in Germany in particular, some of them settling in the region that is today known as Saxony. Their steady expansion ultimately brought them into conflict with the Franks, and once Charlemagne became king of the Franks, friction turned to out-and-out war. The Saxons were among the last peoples of Europe to retain their pagan gods, and Charlemagne became determined to convert the Saxons to Christianity by any means necessary. Charlemagnes war with the Saxons lasted 33 years, and in all, he engaged them in battle 18 times. The Frankish king was particularly brutal in these battles, and ultimately, his ordered execution of 4500 prisoners in one day broke the spirit of resistance the Saxons had displayed for decades. The Saxon people were absorbed into the Carolingian empire, and, in Europe, naught but the duchy of Saxony remained of the Saxons.

Pollution Control Issues Essay Example | Topics and Well Written Essays - 750 words

Pollution Control Issues - Essay Example Introduction to Policy Area Pollution control is a major policy area of not only national but also global importance. We generally agree that pollution of land, water, and air should be controlled. But when it is the question of designing these controls or ascertaining that how much control is sufficient, major disagreements begin to surface. In this regard, Crandall states, â€Å"In 1970, popular concern about environmental degradation coalesced into a major political force, resulting in President Richard Nixon’s creation of the federal Environmental Protection Agency (EPA) and the first of the major federal attempts to regulate pollution directly—the Clean Air Act Amendments of 1970.† With the lapse of time, the federal government took several regulatory majors through the EPA. Non government organizations, research organizations, civil activists, etc. also got involved in the process. The contemporary trend in this policy area is to consider market based metho ds and strategies for pollution control. According to many legislators and lobbyists, the traditional command and control model is not working effectively enough. Classic Iron Triangle Structure Before describing what the classic iron triangle in the context of pollution control would look like, let’s focus on the concept of iron triangle itself. In U.S. politics, iron triangle defines the threefold interaction between the congressional committees, the interest groups, and the governmental agencies. Clientele directed executive functionary mechanism is the main characteristic of iron triangle, which may harm or neglect the greater public interest and provide benefit to the interest groups that are mainly formed of powerful corporate bodies (Hix, 251). The diagram below represents the iron triangle in the sphere of pollution control policy area. In the case of the policy area of pollution control, at one corner of the triangle will be the U.S. Congress Senate Committee on Envi ronment and Public Works, which is a major congressional committee that provides oversight and funds. On the other corner, there will be the EPA, which is a part of bureaucracy, or in other words, the executive of the governmental agencies. At the third corner, there will be the interest groups, which are major corporate bodies, particularly the energy and chemical giants. Significance of Issue Networks Issue networks can be defined as allied structures of several individuals and interest groups that attempt to promote an issue in the federal policy making and think tank. Landy and Milkis think that issue networks are instrumental in balancing rights and democracy vis-a-vis the political tradition and formation of sub-government of iron triangles. Issue networks are a sort of fluid mechanism that would provide the constituency of general public a practical and supple organization, which can accelerate a sustained civil action. In the context of pollution control we can say that the powerful corporations pursue the Congress members and EPA to loosen the regulations so that less money can be invested to obtain improved pollution controlling technologies that are relatively costlier or call for industrial unit replacements. Pollution control issue network can become a contextual counterbalancing factor, where people will have voice. Research organizations, civil activists, non government agencies, independent observers, social

Review of secondary data is applied to understand the value of loyalty programmes to businesses while a survey among hotels is conducted to examine its value to the hotels. Loyalty Programmes are defined as â€Å"schemes offering delayed, accumulating economic benefits to consumers who buy the brand†. Satisfaction does not equal loyalty.
