Teaching research data management courses in higher learning institutions in Tanzania

This research article was published by Emerald Publishing Limited, 2022Purpose – The study investigated teaching research data management (RDM) courses in higher learning institutions (HLIs) in Tanzania to enable postgraduate students to work with their research data. Design/methodology/approach – The study triangulated research methods. Postgraduate students were investigated using survey questionnaires to learn about their needs and perceptions of the teaching RDM courses in HLIs. Key informants (academicians, information and communication technologists and library staff) were also investigated using in-depth interviews to explore their experiences and knowledge of teaching RDM courses. SPSS statistical software was used for analysing quantitative data; qualitative data were analysed thematically. Findings – A total of 70 questionnaires were distributed to postgraduate students with a returning rate of 44 (69%). On the other hand, 12 key informants were interviewed. A low level of RDM literacy was revealed among 38 (86%) respondents. Most respondents 40 (91%) reported the need for HLIs to start teaching RDM courses. A lack of skills and knowledge in teaching RDM courses was revealed among key informants. The competency based, adaptive and constructive teaching techniques were selected for teaching RDM courses, whereas intensive training and online tutorials were revealed as teaching formats. Research limitations/implications – This study focused on teaching RDM courses in HLIs. The survey questionnaires were distributed to all 2nd year postgraduate students, however, the findings cannot be generalised to all postgraduate students due to the response rate obtained. The findings obtained from key informants can also not be used as a basis for generalization across HLIs. Practical implications – This study concluded that postgraduate students need to be well equipped with skills and knowledge on RDM and its related concepts; teaching RDM courses should be regarded as a continuous programme for benefit of students, researchers and the community at large. Social implications – Appropriate teaching of RDM courses among students not only ensures that students meet the funders’ and publishers’ requirements, but also encourages students to store and share their research among researchers worldwide; thus increasing collaboration and visibility of the datasets and data owners through data citations and acknowledgements. Originality/value – This is a comprehensive study that provides findings for HLIs to teach RDM courses in HLIs, especially for postgraduate students. The findings revealed the need for teaching RDM courses in HLIs. The study provides the basis for further RDM research in HLIs and research institutions

Research Data Management Among Researchers in Higher Learning Institutions of Sub-Saharan Africa

This book chapter published by IGI Global, 2020Advancement in information and communication technologies has made it easier for researchers to capture and store myriad data at a higher level of granularity. Higher education institutions (HEIs) worldwide are incorporating research data management (RDM) services to enable researchers to work with their data properly. This chapter focuses on creating awareness amongst researchers on how researchers and HEIs can form strategies, design and restrict data management plan (DMP), integrate research data life cycle, and ensure quality data sharing, as well as integrate with developed RDM policies and guidelines to curb challenges prohibiting the practice of RDM in HEIs

Analytical methods used in estimating the prevalence of HIV/AIDS from demographic and cross-sectional surveys with missing data: a systematic review.

BACKGROUND: Sero- prevalence studies often have a problem of missing data. Few studies report the proportion of missing data and even fewer describe the methods used to adjust the results for missing data. The objective of this review was to determine the analytical methods used for analysis in HIV surveys with missing data. METHODS: We searched for population, demographic and cross-sectional surveys of HIV published from January 2000 to April 2018 in Pub Med/Medline, Web of Science core collection, Latin American and Caribbean Sciences Literature, Africa-Wide Information and Scopus, and by reviewing references of included articles. All potential abstracts were imported into Covidence and abstracts screened by two independent reviewers using pre-specified criteria. Disagreements were resolved through discussion. A piloted data extraction tool was used to extract data and assess the risk of bias of the eligible studies. Data were analysed through a quantitative approach; variables were presented and summarised using figures and tables. RESULTS: A total of 3426 citations where identified, 194 duplicates removed, 3232 screened and 69 full articles were obtained. Twenty-four studies were included. The response rate for an HIV test of the included studies ranged from 32 to 96% with the major reason for the missing data being refusal to consent for an HIV test. Complete case analysis was the primary method of analysis used, multiple imputations 11(46%) was the most advanced method used, followed by the Heckman's selection model 9(38%). Single Imputation and Instrumental variables method were used in only two studies each, with 13(54%) other different methods used in several studies. Forty-two percent of the studies applied more than two methods in the analysis, with a maximum of 4 methods per study. Only 6(25%) studies conducted a sensitivity analysis, while 11(46%) studies had a significant change of estimates after adjusting for missing data. CONCLUSION: Missing data in survey studies is still a problem in disease estimation. Our review outlined a number of methods that can be used to adjust for missing data on HIV studies; however, more information and awareness are needed to allow informed choices on which method to be applied for the estimates to be more reliable and representative

Antecedents for the Utilisation of Web 2.0 Tools for Knowledge Management Practices in Academic Libraries of Tanzania

This research article published by Library Philosophy and Practice (e-journal), 2019The purpose of this paper was to investigate the antecedents for the utilisation of Web 2.0 tools to enhance Knowledge Management (KM) practices in academic libraries of Tanzania. Eight out of the twelve academic libraries were selected. Data gathered through questionnaires distributed to library staff (n= 278), with a response rate of 91.36%. The study used the DeLone and McLean Information System (IS) Success Model to come up with KMS Success Model. Thus, the KMS Success Model was empirically via a Structural Equation Modeling (SEM) approach to examine the antecedents for the utilisation of Web 2.0 tools for the KM practices in academic libraries. The findings reveal that service quality increases user satisfaction and intention to use Web 2.0 tools. Knowledge quality and system quality increase the intention to use and net benefits of using Web 2.0 tools. Further, user satisfaction increases intention to use and net benefits, whereas intention to use increases the net benefits of using Web 2.0 tools to enhance KM practices in academic libraries. This study was conducted to introduce new direction of KM practices through the application of Web 2.0 tools. DeLone and McLean IS Model was used to develop KMS success model which was tested and proved positive significant in KM practices and in facilitating libraries services

Dissemination of Agro-based Information by Telecentres among Selected Rural Farmers in Tanzania with a focus on Moshi Rural District, Kilimanjaro Region

The study assessed the role of Telecentres in the dissemination of agro-based information among selected farmers in rural areas of Tanzania. A cross-sectional study design was conducted in Moshi Rural District, in Kilimanjaro Region, Tanzania. A total of 442 rural farmers aged 21-60 years were randomly selected as study respondents. Questionnaires were used to collect data from respondents. The study found that 205 (55%) respondents were not aware of the existence and services offered among Telecentres, whereas only 12 (7%) respondents reported visiting Telecentres once per day, and 70 (41%) once per year. A total of 140 respondents selected computer services including internet, printing, and scanning to be available among Telecentres. 162 respondents recommended promotion and marketing strategies to enhance the usage of Telecentres among rural farmers was recommended by 162 respondents, while 200 requested agro-based information on crop diseases and pest problems. Inadequate agro-based information in the local language (Swahili) was reported among the challenges hindering the usage of Telecentres among 180 respondents. We recommend the government to exploit the potential of Telecentres in the dissemination of agro-based information among farmers and societies at large

Prevalence,awareness and factors associated with hypertension in North West Tanzania.

BACKGROUND: Hypertension is a public health problem, and yet few people are aware of it and even fewer access effective treatment. With the ongoing demographic transition in many parts of Sub-Saharan Africa, people are changing from rural, manual work to urban lifestyles, hence the risk of hypertension increases. OBJECTIVE: This study aimed at determining the prevalence, awareness and risk factors associated with hypertension in North West Tanzania. DESIGN: A community-based cross-sectional study was conducted among adults in Magu District in 2013. Information on socio-demographic, economic and lifestyle characteristics, medical conditions, and risk factors for hypertension were collected according to the WHO Steps survey tool. Measurements of blood pressure, blood sugar, pulse rate, and anthropometry were taken. Multivariate logistic regression was used to estimate the odds ratios (OR) and 95% confidence intervals (95% CI) for factors associated with hypertension (Blood pressure ≥140/90mm/Hg). Frequencies and percentages were used to determine the awareness, and treatment among hypertensive participants. RESULTS: Among 9678 participants, the prevalence of hypertension was 8.0% and pre-hypertension 36.2%. There was a higher prevalence of hypertension at older ages, among females (8.2%) compared to males (7.7%), and among urban dwellers (10.1%) compared to rural residents (6.8%). Overweight, obese, and diabetic individuals had a higher risk of hypertension while HIV positive participants had a lower risk of hypertension (OR = 0.56; 95% CI 0.39 - 0.79). Among participants with hypertension, awareness was less than 10%. CONCLUSION: By integrating blood pressure screening into our long-standing community HIV screening program, we were able to identify many previously undiagnosed cases of hypertension and pre-hypertension. Age, residence, overweight and obesity were the major associated factors for hypertension. Awareness and treatment rates are very low indicating the need for programs to improve awareness, and treatment of hypertension

Food Insecurity and Intimate Partner Violence in Mwanza, Tanzania: A Longitudinal Analysis

Introduction: Food insecurity is a potential predictor of intimate partner violence. This study (1) describes the prevalence of food insecurity and various forms of intimate partner violence experience among women in Mwanza, Tanzania; and (2) assesses the effect of food insecurity and hunger on various forms of women's experience of intimate partner violence longitudinally. Methods: Women (aged 18–70 years) who reported being in a relationship in the past 12 months, who had participated in the control arms of two randomized controlled trials conducted as part of the MAISHA study were interviewed at four time points (N=1,004 at baseline in 2017). Analyses were conducted in 2022. Associations between food insecurity exposures and intimate partner violence outcomes were assessed, and univariate random effect logistic models were conducted to identify relevant sociodemographic variables (including age, education level, and SES) that were statistically significant. Multivariable random effects logistic models were conducted, including time as a fixed effect, to calculate odds ratios indicating associations between food insecurity exposures and intimate partner violence outcomes. Results: Prevalence of food insecurity was 47.7%, 55.6%, 47.2%, and 50.8% for each of the 4 waves, respectively, with significant difference in proportion of food insecurity between baseline and Wave 2. Multivariable random effects models indicated that food insecurity was associated with increased odds of exposure to all forms of intimate partner violence outcomes, and hunger was significantly associated with increased odds of experience of all intimate partner violence outcomes, apart from controlling behaviors. Conclusions: Results from this longitudinal analysis of food insecurity and women's reports of intimate partner violence experience in a low- and middle-income country setting indicate that food insecurity is significantly associated with all forms of intimate partner violence, apart from controlling behaviors, among women in this sample in Mwanza, Tanzania. Policy and programmatic implications include the need for integrated intimate partner violence prevention programming to take into account household food needs

The association between alcohol consumption and intimate partner violence in young male perpetrators in Mwanza, Tanzania: a cross-sectional study

BACKGROUND: Although alcohol consumption is a well-known risk factor for intimate partner violence (IPV) perpetration, few studies have been conducted among young males in low- and middle-income countries. Alcohol consumption and IPV are both complex phenomena, whose association requires more in-depth exploration regarding drinking patterns and the alcohol-related manifestation of five different forms of IPV. OBJECTIVE: In this study, we sought to explore the relationship between alcohol use and IPV in young Tanzanian men and to identify differences in the magnitude of past-year IPV perpetration among alcohol drinkers and abstainers. Furthermore, we aimed to assess the association between various drinking patterns with the perpetration of different forms of IPV. METHODS: A cross-sectional survey of 1002 young males residing in Mwanza, Tanzania, was conducted in 2021-2022. Data on alcohol consumption were collected using the alcohol use disorder identification test. IPV perpetration was assessed using an index total of 19 items on acts of physical, sexual, economic, emotional abuse, and controlling behaviour. Logistic regression models were conducted to estimate the relationship between alcohol use and the perpetration of each form of IPV. RESULTS: Among partnered respondents currently consuming alcohol (n = 189, 18.8%), the most and the least prevalent IPV forms in the past 12 months were controlling behaviour (84.1%) and physical IPV (25.4%), respectively. Those reporting recent alcohol consumption reported higher rates of all forms of past-year IPV perpetration compared to abstainers. While no form of IPV was associated with low-risk consumption versus abstention, all forms of IPV were associated with hazardous drinking. CONCLUSION: Young men who drink alcohol, especially those drinking hazardously, are also more likely to report perpetrating IPV. An understanding of the different drinking patterns and manifestations of forms of IPV can contribute to better-tailored alcohol-related interventions and has the potential to improve young adults' health and reduce IPV perpetration

Prevalence of high blood pressure and associated factors among adolescents and young people in Tanzania and Uganda.

We conducted a cross-sectional study among school/college students in Tanzania and Uganda to determine the prevalence of high blood pressure (BP) and associated factors. Participants were classified to have high BP if they had pre-hypertension or hypertension. Interviews were done using the WHO STEPS instrument. Using data from both countries (n = 1596), the overall prevalence of high BP was 40% (95% CI: 37-42). The prevalence of pre-hypertension was 29% (95% CI: 26-31) and that of hypertension was 11% (95% CI: 10-13). High BP was independently associated with obesity (aOR = 6.7, 95% CI: 2.2-20.0), male sex (aOR = 3.2, 95% CI: 2.4-4.4), and among males aged above 20 years (aOR = 5.5, 95% CI: 2.9-10.5). Consumption of fruits/vegetables was associated with decreased odds for high BP (aOR = 0.7, 95% CI: 0.50-0.98). The increasing burden of pre-hypertension across age groups could explain the early onset of hypertension and cardiovascular diseases (CVDs) among young African adults. There is a need for longitudinal studies to explore the drivers of pre-hypertension in East African adolescents
