Uganda is recognised as an early success story in the HIV epidemic at least in part due to an open and vigorous national dialogue about HIV prevention. This study examined the national discourse about HIV, AIDS, and young people in New Vision, Uganda's leading national newspaper between 1996 and 2011, building from a previous archival analysis of New Vision reporting by Kirby (1986–1995). We examined the continuing evolution in the public discourse in Uganda, focusing on reporting about young people. An increase in reporting on HIV and AIDS occurred after 2003, as antiretroviral treatment was becoming available. While the emphasis in newspaper reporting about adults and the population at large evolved to reflect the development of new HIV treatment and prevention methods, the majority of the articles focused on young people did not change. Articles about young people continued to emphasise HIV acquisition due to early and premarital sexual activity and the need for social support services for children affected by HIV and AIDS. Articles often did not report on the complex social conditions that shape HIV-related risk among young people, or address young people who are sexually active, married, and/or HIV-infected. With HIV prevalence now increasing among young people and adults in Uganda, greater attention to HIV prevention is needed.  相似文献

As antioxidants play a protective role in the pathophysiology of diabetes and cardiovascular diseases, understanding the physiological status of antioxidant concentration among people at high risk for developing these conditions, such as Metabolic Syndrome, is of interest. In present study out of 187 first degree non-diabetic relatives and 192 non-diabetic spouses, 33.1% and 19.7% were found to have metabolic syndrome respectively. Subjects with metabolic syndrome (≥3 risk factors) had poor antioxidants status as reflected by significantly low levels of vitamin A, C & E and significantly increased (p<0.01) oxidative stress as compared to those without metabolic syndrome. At the same time serum insulin levels and insulin resistance were found to be significantly high (p<0.001) in metabolic syndrome. A strong positive correlation (r=0.946; p<0.001) between oxidative stress and insulin resistance was observed in metabolic syndrome. Low levels of antioxidants and increased oxidative stress with insulin resistance in metabolic syndrome suggests that besides therapeutic life style changes (TLC) as suggested in ATP III guidelines inclusion of antioxidant vitamins, fruits and vegetable could be beneficial to ward off the consequences of metabolic syndrome.  相似文献

This article explores linguistic-cultural ideologies and educational policies as they emerge and are negotiated in everyday life in a bilingual school setting located in the geopolitical spaces of Sweden. Taking sociocultural theory and discourse analysis as points of departure, we focus on empirical examples of classroom interaction and locally established formal policing. Linguistic-cultural ideologies and educational policies that frame life at the school are investigated by employing nexus analytical methods, focusing on social (inter)actions through which a number of locally and nationally relevant discourses circulate. Our findings indicate that refocusing ideology and policy research from the lens of a practiced perspective allows the situated and distributed nature of everyday life to inform issues related to bilingualism as well as their relations to wider societal discourses. Furthermore, our analysis highlights the crucial role of educators in (re)locating bilingual education in its societal contexts as well as making these connections visible in classrooms.  相似文献

A high circulating concentration of the non proteinogenic amino acid homocysteine has been implicated as a risk factor for Alzheimer’s Disease and its prodromal stage, mild cognitive impairement. Furthermore, hyperhomocysteinaemia has been directly attributed to a deficiency in vitamins B12, folate, and B6. Several studies have demonstrated decrease in progression of mild cognitive impairement to Alzheimer’s Disease, and some have even shown an improvement in cognition after vitamin supplements with B12 and folate. Plausible mechanisms linking hyperhomocysteinaemia to Alzheimer’s and cognitive impairement have been hypothesized and demonstrated in hyperhomocysteinemic mice models. However, some studies have not elucidated any benefit of vitamin supplements in subjects with cognitive impairment. Hence, multicentric clinical studies need to be conducted to substantiate the mechanisms of neuronal degeneration due to hyperhomocysteinaemia and to demonstrate the beneficial effect of folate, B6 and B12 supplements on cognition.  相似文献

Classroom     
In this section of Resonance, we invite readers to pose questions likely to be raised in a classroom situation. We may suggest strategies for dealing with them, or invite responses, or both. “Classroom” is equally a forum for raising broader issues and sharing personal experiences and viewpoints on matters related to teaching and learning science.  相似文献

Silver is ingested in India in the form of varak, Ayurvedic bhasm and water contained in silver utensils, but nobody knows their effects. We have examined the effect of interaction of silver ingested in the form of varak (leaf), bhasm (ash) and water (colloidal solution) on some essential elements (Na, K, Ca, Mg, Cu, Fe and Zn) in blood, liver, spleen and kidneys of chicks. The results showed significant rise of silver in all the tissues and significant fall in copper in the blood. The greatest rise was obtained in blood silver by silver sol while it had the lowest amount of silver. Iron significantly increased in tissues but somewhat decreased in blood. Zinc content increased in all the tissues by leaf and ash but decreased by sol. No consistent pattern was seen in case of other elements.  相似文献

The application of ICT solutions for the development of rural India and other developing countries opens up a vast range of possibilities. Giving an opportunity to the vast majority of the population living in rural areas, to cross the digital divide to obtain access to information resources and services provided by ICT is the next revolution waiting to happen. Although this is a development issue, it is just not the government, non-government organizations or the rural masses that have a role to play. Private profit-making institutions can develop solutions to capture the hitherto unrecognized markets, make profits and at the same time aid the rural societies. The new technologies being developed can help surmount barriers present in providing information resources at a low cost and make applications feasible and profitable. This paper presents some cases where ICT has been effectively used for the benefit of the rural societies and analyzes the opportunities that lie in this sphere. The cases range from successful use of ICT in governance, to ICT solutions for improved profits to ICT in microfinance. A case of an initiative by a large mainstream corporation to reach out to the rural sector, help in development and realize profits mutually is also presented. The projects discussed should generate more interest and facilitate private investment in the hitherto virgin territory. A large number of hurdles still remain but creative ideas, breakthrough ICT technologies and committed organizations can usher in the next revolution in the developing world.  相似文献

We present here a qualitative test that distinguishes between monosaccharides, reducing disaccharides, non-reducing disaccharides, aldoses and ketoses using alkaline potassium ferricyanide. This is a simple, quick and unambiguous test to distinguish various carbohydrates from one another and is reliable enough to replace other tests reported in standard laboratory textbooks.  相似文献

ObjectiveThe aims of this cross-sectional survey were to examine the prevalence, type and intensity of abuse in street children in Jaipur city, India.MethodBased on purposive random sampling, 200 street children, inclusive of equal number of boys and girls, were selected from the streets of Jaipur city, India, and administered an in-depth interview schedule which included five areas of abuse, namely, “general abuse,” “health abuse,” “verbal abuse,” “physical abuse,” and “psychological abuse.” Data was interpreted using percentages, t-test and correlations.ResultsStreet children reported experiences of abuse in all the five areas under study. Larger numbers of children (61.8%) scored in the “moderate” category of abuse while 36.6% children indicated abuse in “severe” and “very severe” categories on the intensity of abuse. Highest mean scores were obtained on the “verbal” and “psychological” area of abuse. Gender differences were significant in health and overall abuse, indicating boys to be significantly more abused than girls. There were significant positive correlations of abuse with increasing “age” and “income” of street children; and the occurrence of “multi-type” maltreatment and neglect in street children was clearly present.ConclusionDifferent forms of abuse are prevalent in street children in India. This area of study needs attention both by the researchers and the social workers.Practice implicationschildren who are identified in severe and very severe categories of abuse should be worked with in a follow up study with the help of governmental and nongovernmental agencies working in the field for child welfare.  相似文献
