BackgroundHIV infection has been modifying both the epidemiology and outcome of parasitic infections. Hence, this study was undertaken to determine the prevalence of intestinal parasitic infection among people with and without HIV infection and its association with diarrhea and CD4 T-cell count.MethodsA cross-sectional study was conducted at Hawassa Teaching and Referral Hospital focusing on HIV positive individuals, who gave blood for CD4 T-cell count at their first enrolment and clients tested HIV negative from November, 2008 to March, 2009. Data on socio-demographic factors and diarrhea status were obtained by interviewing 378 consecutive participants (214 HIV positive and 164 HIV negative). Stool samples were collected from all study subjects and examined for parasites using direct, formol-ether and modified acid fast stain techniques.ResultsThe prevalence of any intestinal parasitic infection was significantly higher among HIV positive participants. Specifically, rate of infection with Cryptosporidium, I. belli, and S. stercoralis were higher, particularly in those with CD4 count less than 200 cells/μL. Diarrhea was more frequent also at the same lower CD4 T-cell counts.ConclusionImmunodeficiency increased the risk of having opportunistic parasites and diarrhea. Therefore; raising patient immune status and screening at least for those treatable parasites is important.

STEM, a set of fields that includes science, technology, engineering, and mathematics; allied disciplines ranging from environmental, agricultural, and earth sciences to life science and computer science; and education and training in these fields, is clearly at the top of the list of priority funding areas for governments, including the United States government. The U.S. has 11 federal agencies dedicated to supporting programs and providing funding for research and curriculum development. The domain of STEM education has significant implications in preparing the desired workforce with the requisite knowledge, developing appropriate curricula, providing teachers the necessary professional development, focusing research dollars on areas that have maximum impact, and developing national educational policy and standards. A complex undertaking such as STEM education, which attracts interest and valuable resources from a number of stakeholders needs to be well understood. In light of this, we attempt to describe the underlying structure of STEM education, its core areas, and their relationships through co-word analyses of the titles, keywords, and abstracts of the relevant literature using visualization and bibliometric mapping tools. Implications are drawn with respect to the nature of STEM education as well as curriculum and policy development.

Purpose – The study aimed to investigate the perceptions of faculty members at a medium-sized university towards self-archiving and participation in institutional repositories (IRs). Design/methodology/approach – The research participants were from a medium-sized university. An online survey was distributed and a total of 217 responses were received which yielded a 40 per cent overall response rate. Faculty perceptions of the IR were measured through nine dimensions, the results of which were later summarised using principal component factor analysis. Findings – Faculty members’ perception of IRs and willingness to contribute to the IRs were closely associated with scholarly productivity rather than prior knowledge of and experience with IRs. Those who possessed scholarly materials were significantly more likely to have a positive perception of IRs and, therefore, were more likely to contribute to IRs than those who did not. Seniority in faculty rank contributed negatively to faculty members’ perception of the repository. Research limitations/implications – The study used a non-probability sampling technique to collect data about the faculty’s perception of IRs at a single institution of higher education. Variables for faculty background were limited to rank and academic discipline. Originality/value – In three ways: First, the study contributed to research on faculty perception of IRs in academia and approached the issue from the perspective of a teaching-oriented institution. Second, the relationship between faculty's willingness to participate in and their perception of IRs was measured. Third, a binary logistic regression model was used to estimate factors that influence faculty's perception of the institution's IRs.

Purpose The purpose of this study is to investigate information seeking behavior of immigrants in disadvantaged communities in the state of CO, USA, using school choice decisions as a problematic situation. The study investigated the extent to which immigrant families in poor neighborhoods took advantage of school choice policies and the extent to which these decisions were mediated by information seeking activities. Design/methodology/approach Quantitative study using survey questionnaire was used. The study design used everyday life information seeking behavior (Savolainen, 1995) and information-poverty lived-experiences of poor people (Chatman and Pendelton, 1995) as a framework and theoretical lens, respectively. Parents of school-age children who met the criteria of “poor” based on the federal poverty guideline were recruited to participate in the study. Findings The study found that only 21 per cent (24 families out of 113) participated in school choice programs. Within the smaller group of parents that took advantage of school choice policy, 72 per cent gathered information before choosing a school, and of this group, about 80 per cent asked friends followed by school visit and a phone call to schools as information sources. Library use as sources of information was also selected by 61 per cent of the respondents. One important finding of this study is that although a majority of the families are aware of school choice policy, their level of participation is low and that is largely due to their economic and life circumstances. Social implications Access to quality education is widely investigated and multiple entities have a stake in it, including parents, policymakers, researchers and school districts. The social implications of this study are significant in that the mere presence and awareness of school choice policy did not translate into increased participation by parents from disadvantaged communities for whom the policy was designed to benefit. Consistent with findings in the extant literature, parents in low socio-economic status also value quality education for their children. To address the issue of low participation in school choice, cities need to work toward strengthening schools and library systems in poor neighborhoods instead of diverting resources away. Originality/value Based on two theoretical accounts – i.e. the information-poverty lived-experiences of poor people, or the outsiders, (Chatman, 1999, 1996), and theory of everyday life information seeking (Savolainen, 1995) – this study investigated how immigrants and disadvantaged communities seek, acquire and use information to navigate school choice policy in the city of Aurora, CO. The findings of this study are relevant for educators, policymakers, libraries, school districts, cities, counties and parents to determine the necessary policy measures that are required to increase school choice participation by immigrants and disadvantaged communities.

Rainwater harvesting is the process of intercepting, conveying and storing rainfall for future use as an alternative source of water in the drought prone areas of Ethiopia especially eastern Oromia. The aim of the research was to assess and mapping suitability area of water harvesting site in Daro Labu District. There are various methodologies and criteria to identify suitable sites and techniques for rainwater harvesting (RWH). Determining the best method or guidelines for site selection, however, is difficult. GIS is the recent technology of spatiotemporal data used to assess the factor of influences for rainfall and runoff depth estimation for identification of potential area of RWH for crop production and mapping of the potential site. The influence factors for consideration of the assessment was climate data, soil texture and depth, land use and land cover (LULC) type, slope difference were used. The total area of the catchment was about 156064.72 ha. The SCS-CN for rainfall used to runoff depth estimation compute runoff and volume from the land surface depend on the level of antecedent moisture condition (AMC.) The length of wet and dry season of the study area were known with antecedent moisture condition (AMC) of II, I III by having the values of 82, 67 and 91 respectively. The annual of 20 years average rainfall was 925.2 mm with maximum and minimum of 1134 mm and 737.3 mm respectively with average annual runoff depth of estimate was 185.3 mm. From the estimated annual runoff the volume of water harvested was about 2.89 × 10 8 m 3 . The suitability map of the study area shows extremely potential, highly potential, potential and not potential accounts by coverage areas about (12,797.3 ha) 8.2%, (25,906.7 ha) 16.6%, (98,302.8 ha) 63.5%, and (19,040 ha) 7.5% respectively. The runoff in the study area was affected by geomorphological factors, particularly, land use change, topography, soil texture and depth, drainage density, and population density affects the runoff rate and volume significantly.
