hs-CRP: A potential marker for hypertension in Kashmiri population

Hypertension is the most important public health problem in developing countries and one of the major risk factors for cardiovascular diseases, and it has been reported that hypertension is in part an inflammatory disorder and several workers have reported elevated levels of CRP in hypertensive individuals. The main aim of the present study was to evaluate the association between blood pressure and serum CRP levels across the range of blood pressure categories including prehypertension. A total of 104 patients and 63 control subjects were included in the present study. The level of CRP in the serum samples was estimated by a high sensitivity immunoturbidometric assay. Standard unpaired student’s ‘t’ test was used for comparison of hs-CRP levels between hypertensive patients and normotensive control subjects and between patient groups with different grades of hypertension and different durations of hypertensive histories. The mean serum hs-CRP level in hypertensive patients was 3.26 mg/L compared with 1.36 mg/L among normotensive control subjects (P<0.001). On comparison with normotensive control subjects, the hs-CRP levels vary significantly both with grades and duration of hypertension, with most significant difference found in patients with prehypertension (P<0.001), followed by Stage-I (P=0.01) and Stage-II(P=0.02) hypertensives. Significant difference in hs-CRP levels was also found in patients with shorter duration of hypertensive history (≤ 1year) when compared with those with ≥5 years of hypertensive history (P<0.01). Our study reveals a graded association between blood pressure and CRP elevation in people with hypertension. Individuals with prehypertension or with shorter duration of hypertension (≤1 Year) had significantly a greater likelihood of CRP elevation in comparison to chronic stage-I or stage-II hypertensives.     

Things Fall Apart and Come Together: Using the Visual for Reflection in Alternative Teacher Education Programmes

In this article, we focus on the use of the visual for reflection in ‘alternative’ pre‐service teacher education and, in particular, we address the question: How and what can we learn about teacher education using the visual? By way of illustration, we focus on the use of pre‐service teachers’ photographs in a public exhibition, participatory video documentary production and pre‐service teachers’ use of photographs in their professional teaching portfolios. The article draws from research done in relation to three alternative pre‐service teacher education projects based at McGill University in Canada and the University of KwaZulu‐Natal in South Africa.     

Barcode technology and its use and applications: A study of selected libraries of Bangladesh

This study explored the usage and applications of barcode technologies through a survey carried out in eight libraries in Dhaka City of Bangladesh. The survey included the following: Inception year, software used to barcode, areas in which barcodes are being used in libraries, training of library staff, and satisfaction of users and information professionals. The merits and demerits of barcode technologies are presented.     

A genetically modified fuzzy linear discriminant analysis for face recognition

This paper addresses the face recognition problem through a modification of the Fuzzy Fisherface classification method. In conventional methods, the relationship of each face to a class is assumed to be crisp. The Fuzzy Fisherface method introduces a gradual level of assignment of each face pattern to a class, using a membership grading based upon the K-Nearest Neighbor (KNN) algorithm. This method was further modified by incorporating the membership grade of each face pattern into the calculation of the between-class and within-class scatter matrices, termed as Complete Fuzzy LDA (CFLDA). The present work aims at improving the assignment of class membership by improving the parameters of the membership functions. A genetic algorithm is employed to optimize these parameters by searching the parameter space. Furthermore, the genetic algorithm is used to find the optimal number of nearest neighbors to be considered during the training phase. The experiments were performed on the Olivetti Research Laboratory (ORL) face image database and the results show consistent improvement in the recognition rate when compared to the results from other techniques applied on the same database and reported in literature.     

Representations of swine flu: perspectives from a Malaysian pig farm

Novel influenza viruses are seen, internationally, as posing considerable health challenges, but public responses to such viruses are often rooted in cultural representations of disease and risk. However, little research has been conducted in locations associated with the origin of a pandemic. We examined representations and risk perceptions associated with swine flu amongst 120 Malaysian pig farmers. Thirty-seven per cent of respondents felt at particular risk of infection, two-thirds were somewhat or very concerned about being infected. Those respondents who were the most anxious believed particular societal "out-groups" (homosexuals, the homeless and prostitutes) to be at higher infection risk. Although few (4%) reported direct discrimination, 46% claimed friends had avoided them since the swine flu outbreak. Findings are discussed in the context of evolutionary, social representations and terror management theories of response to pandemic threat.     

Nostalgic Emotional Appeals for Smoking Prevention

Nostalgia-evoking messages are used to promote consumer products, but their use for encouraging healthy behaviors is not well understood. This study examines the use of nostalgia as an emotional appeal to influence attitudes and reduce smoking behavior. The study hypothesized that exposure to a nostalgic public service announcement (PSA) will result in (a) more negative attitude toward smoking; and (b) increased intention to limit smoking, relative to a control. Participants exposed to the nostalgia-evoking PSA expressed more negative attitudes toward smoking and stronger intentions to limit smoking than did participants exposed to nonnostalgic messages. The findings suggest nostalgic appeals as a promising strategy for smoking prevention messages.     

What do they like? Communication preferences and patterns of older adults in the United States: The role of technology

ABSTRACT

With the development of information and communication technologies (ICTs), there are increasingly more Internet-based communication methods available for older adults besides traditional methods (e.g., in-person or landline phone). However, older adults’ preferred communication methods remain under-investigated. The purpose of this study is to explore the communication preferences and patterns of older adults in the United States, with emphasis on technologically-mediated environments. In this study, 17 semistructured interviews were conducted with participants from a midwestern state in the United States. The goal was to examine older adults’ communication patterns and preferences with family members and friends, as well as their views about the impacts of modern technology on communication. Three themes (communication preferences and reasons, communication barriers, and the impacts of technology) were generated from the interviews. The findings showed that although face-to-face communication is the most preferred method, telephone communication is the most commonly adopted method. Interviewees also shared different opinions regarding Internet-based communication. The current study illustrated the importance of understanding the preferences and patterns of older adults’ communication needs and desires.     

Assessing Community College Student Learning Outcomes: Where are We? What's Next?

The Community College Leadership Consortium is building the Bellwether Coalition for Instructional Leadership toward the development of a voluntary system of accountability for community colleges. In response to the Spellings Commission's national call for accountability in higher education, the consortium and its partners convened an Independent Policy Forum at the 2008 Community College Futures Assembly in Orlando, Florida. The Independent Policy Forum began to develop a set of recommendations to be communicated to the American Association of Community Colleges (AACC) during its 2009 annual meeting. Recommendations put forth by the forum will contain the founding principles for the nascent voluntary system of accountability for community colleges.
