Factors Influencing the Acceptance and Use of Koha Library Software in Academic Libraries of Uganda Introduction and Background of the Study

Purpose: The study aimed at investigating factors that influence acceptance of Koha Integrated Library System (ILS) and its use in academic libraries of Uganda. Design/methodology/approach: The study was based on descriptive crosssectional survey design. A representative sample of 103 was used out of the target population of 140, comprising academic librarians and ICT personnel from four academic libraries in Uganda. Structured self-completion questionnaire, semi-structured interviews and observations were used in data collection. A success response level of 78% of the questionnaires sent out was realized. Data analysis was carried out using SPSS software; to establish the significance level of the factors influencing Koha acceptance. Research limitation(s): Non-academic libraries and patrons were not part of the study population. Key finding(s): The findings from the study indicate that nine factors influence acceptance of Koha in selected academic libraries of Uganda. These include productivity, ease of use, free and open source nature of Koha, peer pressure, availability of resources, domain knowledge, awareness, anxiety and computer literacy levels. Four factors were moderating variable namely age, gender, level of education and experience. System productivity had the highest mean score of 4.20 and the least ranked factor was peer pressure with a mean score of 3.12. Practical implication(s): The study has paved way for academic librarians and managers wishing to adopt Koha in regard to the core system attributes. Contribution to knowledge: The study has contributed new knowledge in the aspect of ascertaining the factors that influence acceptance of Koha in academic libraries of Uganda, specifically system productivity, ease of use. The contribution can act as a basis for further studies

Socio-demographic disparity in oral health among the poor: a cross sectional study of early adolescents in Kilwa district, Tanzania

There is a lack of studies considering social disparity in oral health emanating from adolescents in low-income countries. This study aimed to assess socio-demographic disparities in clinical- and self reported oral health status and a number of oral health behaviors. The extent to which oral health related behaviors might account for socio-demographic disparities in oral health status was also examined. A cross-sectional study was conducted in Kilwa district in 2008. One thousand seven hundred and forty five schoolchildren completed an interview and a full mouth clinical examination. Caries experience was recorded using WHO criteria, whilst type of treatment need was categorized using the ART approach. The majority of students were caries free (79.8%) and presented with a low need for dental treatment (89.3%). Compared to their counterparts in opposite groups, rural residents and those from less poor households presented more frequently with caries experience (DMT>0), high need for dental treatment and poor oral hygiene behavior, but were less likely to report poor oral health status. Stepwise logistic regressions revealed that social and behavioral variables varied systematically with caries experience, high need for dental treatment and poor self reported oral health. Socio-demographic disparities in oral health outcomes persisted after adjusting for oral health behaviors. Socio-demographic disparities in oral health outcomes and oral health behaviors do exist. Socio-demographic disparities in oral health outcomes were marginally accounted for by oral health behaviors. Developing policies and programs targeting both social and individual determinants of oral health should be an urgent public health strategy in Tanzania

Trace Elements and Carbon and Nitrogen Stable Isotopes in Organisms from a Tropical Coastal Lagoon

Trace elements (Fe, Mn, Al, Zn, Cr, Cu, Ni, Pb, Cd, Hg, and As) and stable isotope ratios (δ13C and δ15N) were analyzed in sediments, invertebrates, and fishes from a tropical coastal lagoon influenced by iron ore mining and processing activities to assess the differences in trace element accumulation patterns among species and to investigate relations with trophic levels of the organisms involved. Overall significant negative relations between trophic level (given by 15N) and trace element concentrations in gastropods and crustaceans showed differences in internal controls of trace element accumulation among the species of different trophic positions, leading to trace element dilution. Generally, no significant relation between δ15N and trace element concentrations was observed among fish species, probably due to omnivory in a number of species as well as fast growth. Trace element accumulation was observed in the fish tissues, with higher levels of most trace elements found in liver compared with muscle and gill. Levels of Fe, Mn, Al, and Hg in invertebrates, and Fe and Cu in fish livers, were comparable with levels in organisms and tissues from other contaminated areas. Trace element levels in fish muscle were below the international safety baseline standards for human consumption

Issues arising following a referral and subsequent wait for extraction under general anaesthetic: impact on children

BACKGROUND: Untreated caries in young children can result in a referral for extraction in hospital under general anaesthetic (GA). This study aims to explore the impact of caries during the ensuing wait for GA on children resident in the North West of England. METHODS: The study involved 456 respondents referred to six hospitals in the Northwest of England. Over a two-month period each of these children/ families completed a questionnaire and gave permission to access their referral and consultation notes. RESULTS: Children (6.78 years old: 1.50 to 16.42) had on average five teeth extracted (ranging from one to a full clearance, with all teeth removed). Sixty seven per cent of parents reported their child had been in pain, 26% reported schools days being missed and 38% having sleepless nights. The average time from referral to operation was 137 days. Results indicated that children could be in discomfort during their wait, as pain was experienced, on average, 14 days before the operation. Wait time significantly predicated the number of sleepless nights b = .004, t(340) = 2.276, p = .023. CONCLUSIONS: It is clear that pain, sleepless nights and missed school are a feature during a wait for dental GA and can be exacerbated by an extended wait. These data support the need for not only effective prevention of caries within primary care to reduce wait times and experience of GA but also effective management of pain and infection during a prolonged wait for treatment
