The nature of social accountability in South African medical practice and education: a qualitative reflection

Social accountability describes the extent to which a medical education institution’s research, service and education make a difference to the health status of the community in which they work. An individual practitioner is expected to attain a range of graduate attributes and competencies many of which enable a responsive approach to practice in society

The potential of Library 2.0 for research libraries in Kenya.

Thesis (Ph.D.)-University of KwaZulu-Natal, Pietermaritzburg, 2011.The environment in which libraries currently operate has changed drastically. For instance, the emergence of new information and communication technologies, exemplified by the Internet, has changed the way people seek information, communicate and collaborate. Thus, modern library users have embraced new information seeking behaviour as well as expectations for better usability, faster response times to needs, and constant access to unrestricted library services. As libraries struggle to cope with these changes and user expectations, some library users are already reducing their levels of usage, preferring to “Google” than visit a physical library. Similarly, library circulation statistics indicate that the usage of the traditional services and products is decreasing steadily while the usage of electronic resources and services is increasing. Critically, most users do not presently perceive the library as the first or only stop for information. Libraries are therefore struggling to attract new users and retain the existing ones. Research libraries in Kenya, due to their vision and mission as well as the heightened expectations of the users, are under immense pressure to change. Indeed, a number of them are already changing by introducing new services facilitated by the emerging Information and Communication Technology (ICT) tools. However, the services and products are still limited in scope and depth because they have been patterned after the conventional services. One of the greatest predicaments the research libraries currently face is how to model and manage this change. This study investigated the potential of the Library 2.0 model of library service in facilitating the research libraries in Kenya to respond more closely to the emerging user needs and expectations. The study employed interpretive qualitative research methodology and multiple case studies to investigate the current status of research libraries in Kenya and their challenges in meeting the dynamic needs of the researchers. Furthermore, the study investigated the extent of application and use of the Library 2.0 model. Data was collected from five case study sites – African Medical and Research Foundation (AMREF), International Centre for Research in Agroforestry (ICRAF), International Livestock Research Institute (ILRI), Kenya Agricultural Research Institution (KARI) and Kenya Medical Research Institute (KEMRI) – through interviews of researchers and librarians; focus group discussions with researchers and librarians; Social Network Analysis; direct observations; and mystery shopping. The data was analyzed using content analysis, conversation analysis, descriptive/interpretive techniques (Heideggarian hermeneutics) and Computer Assisted Qualitative Data Analysis Software (CAQDAS) such as Nvivo and UCINET. The findings of this study show that most research libraries in Kenya do not have documented vision, mission or strategic plans; are underfunded and understaffed; hold inadequate collections in equally inadequate physical spaces; largely apply the traditional library service model; face negative internal politics and unfavourable organizational structures; and lack mutually beneficial linkages. The findings also indicate that the research libraries in Kenya are underutilized and barely meet the needs of the researchers in their current status. The findings of this study also suggest that the Library 2.0 model holds great potential to enable the libraries to take their services and products everywhere the researchers are; remove the barriers to accessing library services; facilitate and direct constant purposeful change in their services and how they are delivered; harness the active participation of the users; retain the new breed of users (Patrons 2.0); and remain user-centred. Based on the findings, the researcher recommends that the librarians who head research libraries should hold PhD degrees to enable them to participate effectively in institutional decision-making; the research libraries should establish close ties with academic libraries supporting programmes related to their research interests; the research libraries should form a specialized consortium and association to serve their unique interests; the research libraries should consider grey literature as an important source of research information and develop strategies of managing it; and schools of librarianship should introduce courses on ICTs, models of library service, marketing and facilitation (training) to equip the students with the skills needed to meet the emerging demands on librarians. The researcher also proposes a Research Library 2.0 meme map which is an adaption of the Library 2.0 meme map. The former map is different from latter in that it is specific to research libraries and recognizes the fact that an effective Research Library 2.0 requires the active interaction of enhanced collection (Collection 2.0), library physical space (Physical Space 2.0), researchers (Researcher 2.0) and librarians (Librarian 2.0) to thrive. The researcher also recommends that further research be conducted to investigate the potential of the Library 2.0 model for all the other library typologies in Kenya and Africa; explore the influence of gender on librarianship in Africa; investigate the application of Social Network Analysis in library and information research; and develop an inventory of all types of libraries in Kenya

Mass participation user trials

This thesis investigates how researchers can take advantage of the rapid adoption of mobile technology that has brought with it transformations in social and cultural practice; the expectations of what computers are, what they can do, and the role of digital objects in everyday life. In particular this thesis presents and discuses the use of new App Store style software distribution methods to reduce the cost, in terms of researcher time and hardware, of recruiting a large group of participants for a trial ‘in the wild’ while increasing the potential diversity of users is becoming an attractive option for researchers pursuing the ubicomp vision. It examines the procedures for running large scale trials with the deployment of three applications released to a combined user base of over 135,000 in such a way as to keep the qualitative detail necessary to inform design while gain- ing the diversity of users for claims of generalisability. More generally, it discusses the results that can be expected from this ‘mass participation’ approach, and the ethical responsibilities they place upon researchers. The contributions of this thesis for mobile HCI show that in large-scale trials, relatively rich qualitative data can be collected along with substantial quantitative data, and that a hybrid trial methodology combining a large- scale deployment with a local trial can be a powerful tool in addressing shortcomings of trials that are either solely local or solely global. This thesis also contributes guidelines for researchers running large-scale user trials that give consideration to the established research norms and practices, in an attempt to strike a new balance between invasiveness and utility

Professional development for using technology in mathematics teaching in Ghana

Drawing on the framework of TPACK (technological pedagogical content knowledge) and the principles of effective mathematics pedagogy, this study set out with two aims. First, shifts in teachers’ technology dispositions (beliefs, attitudes, and knowledge) were explored after engagement in the professional development programme mediated with GeoGebra software. Second, typical features and nuances of the complexities of enacting effective mathematics pedagogy in a GeoGebra learning environment were examined. Eleven in-service mathematics teachers from a senior high school in Ghana were engaged in a professional development programme for 12 months. They were introduced to the use of GeoGebra software in mathematics teaching, and then designed GeoGebra-based mathematics lessons, which they taught to their peers and subsequently their students in the mathematics classroom. Self-report questionnaire, interviews, focus group discussions, lesson plans, and lesson observations were used for data collection. The results provided evidence that within Geogebra-based mathematics lessons, teachers were able to enact, to different degrees, five practices central to effective mathematics pedagogy: creating mathematical setting, providing useful mathematical tasks, orchestrating mathematical discussions, making mathematical connections, and assessing students’ learning. Further analysis of the data provided evidence for theorising 31 core practices across these central themes of effective mathematics pedagogy. Following their engagement in the professional development, the teachers enacted these practices to greater or lesser extents. However, it was problematic for most teachers to effectively engage their students in deep mathematical discussion. Engaging teachers to design and teach with GeoGebra in the mathematics content area offered a unique lens for understanding the shift in the teachers’ dispositions towards the use of technology in mathematics teaching and learning. As teachers engaged in using GeoGebra, their knowledge and perceived beliefs about the usefulness and nature of technology in mathematics education became profound. The teachers improved their technological pedagogical content knowledge (TPACK) during the study. Analysis of the components of TPACK showed that they improved their knowledge of the mathematics content as well as knowledge of technology, teaching, and students’ learning. However, their intention to put new pedagogical approaches into classroom practice in the future depended on multiple contextual factors including administrative support, continual professional training, and provision of adequate technology facilities. The findings from this study have implications for Ghana’s senior high school mathematics education, TPACK, effective mathematics pedagogy, professional development, and research methodology

Deprescribing tool for STOPPFall (screening tool of older persons prescriptions in older adults with high fall risk) items

Background: Health care professionals are often reluctant to deprescribe fall-risk-increasing drugs (FRIDs). Lack of knowledge and skills form a significant barrier. To support clinicians in the management of FRIDs and to facilitate the deprescribing process, a deprescribing tool was developed by a European expert group for STOPPFall (Screening Tool of Older Persons Prescriptions in older adults with high fall risk) items. Methods: STOPPFall was created using an expert Delphi consensus process in 2019 and in 2020, 24 panellists from EuGMS SIG on Pharmacology and Task and Finish on FRIDs completed deprescribing tool questionnaire. To develop the questionnaire, a Medline literature search was performed. The panellists were asked to indicate for every medication class a possible need for stepwise withdrawal and strategy for withdrawal. They were asked in which situations withdrawal should be performed. Furthermore, panellists were requested to indicate those symptoms patients should be monitored for after deprescribing and a possible need for follow-ups. Results: Practical deprescribing guidance was developed for STOPPFall medication classes. For each medication class, a decision tree algorithm was developed including steps from medication review to symptom monitoring after medication withdrawal. Conclusion: STOPPFall was combined with a practical deprescribing tool designed to optimize medication review. This practical guide can help overcome current reluctance towards deprescribing in clinical practice by providing an up-to-date and straightforward source of expert knowledge

Association between number of medications and mortality in geriatric inpatients : a Danish nationwide register-based cohort study

Purpose: To explore the association between the number of medications and mortality in geriatric inpatients taking activities of daily living and comorbidities into account. Methods: A nationwide population-based cohort study was performed including all patients aged C65 years admitted to geriatric departments in Denmark during 2005-2014. The outcome of interest was mortality. Activities of daily living using Barthel-Index (BI) were measured at admission. National health registers were used to link data on an individual level extracting data on medications, and hospital diseases. Patients were followed to the end of study (31.12.2015), death, or emigration, which ever occurred first. Kaplan-Meier survival curves were used to estimate crude survival proportions. Univariable and multivariable analyses were performed using Cox regression. The multivariable analysis adjusted for age, marital status, period of hospital admission, BMI, and BI (model 1), and further adding either number of diseases (model 2) or Charlson comorbidity index (model 3). Results: We included 74603 patients (62.8% women), with a median age of 83 (interquartile range [IQR] 77-88) years. Patients used a median of 6 (IQR 4-9) medications. Increasing number of medications was associated with increased overall, 30-days, and 1-year mortality in all 3 multivariable models for both men and women. For each extra medication the mortality increased by 3% in women and 4% in men in the fully adjusted model. Conclusion: Increasing number of medications was associated with mortality in this nationwide cohort of geriatric inpatients. Our findings highlight the importance of polypharmacy in older patients with comorbidities

Physical activity and exercise in dementia : an umbrella review of intervention and observational studies

Background: Dementia is a common condition in older people. Among the potential risk factors, increasing attention has been focused on sedentary behaviour. However, synthesizing literature exploring whether physical activity/exercise can affect health outcomes in people with dementia or with mild cognitive impairment (MCI) is still limited. Therefore, the aim of this umbrella review, promoted by the European Geriatric Medicine Society (EuGMS), is to understand the importance of physical activity/exercise for improving cognitive and non-cognitive outcomes in people with dementia/MCI. Methods: Umbrella review of systematic reviews (SR) (with or without meta-analyses) of randomized controlled trials (RCTs) and observational (prospective and case-control in people with MCI) studies based on a systematic literature search in several databases. The certainty of evidence of statistically significant outcomes attributable to physical activity/exercise interventions was evaluated using Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach. Results: Among 1,160 articles initially evaluated, 27 systematic reviews (4 without meta-analysis) for a total of 28,205 participants with dementia/MCI were included. No observational study on physical activity/exercise in MCI for preventing dementia was included. In SRs with MAs, physical activity/exercise was effective in improving global cognition in Alzheimer’s disease and in all types of dementia (very low/low certainty of evidence). Moreover, physical activity/ exercise significantly improved global cognition, attention, executive function, and memory in MCI, with a certainty of evidence varying from low to moderate. Finally, physical activity/exercise improved non-cognitive outcomes in people with dementia including falls and neuropsychiatric symptoms. SRs, without meta-analysis, corroborated these results. Conclusions: Supported by very low to moderate certainty of evidence, physical activity/exercise has a positive effect on several cognitive and non-cognitive outcomes in people with dementia and MCI, but RCTs, with low risk of bias/confounding, are still needed to confirm these findings
