The paper examines e-government development in Africa. This study is based on the Cape Gateway project in South Africa, a leading e-government initiative on the continent. We observe that African countries have jumped on the e-government band wagon by looking mostly at the benefits without a clear risk assessment. We argue that African countries should question the pace and pathway for their e-government programs. We caution that e-government models from developed countries do not necessarily work in Africa. E-government programs in Africa should be balanced with the provision of basic needs and infrastructure. We conclude that e-government in South Africa should adopt multi-cultural approaches, and must be underpinned by national development priorities. We recommend that the Cape Gateway must address the socio-economic context and needs of the country. The pace and pathway of its e-government must depend on the availability of both financial and human resources and also user satisfaction. 相似文献

Despite our society's increasing reliance on electronic documentation, to-date archives remain, largely, material repositories
of cultural memory. It is an accepted historical problematic, however, that culture is often resistant to material preservation.
There exists an undeniable and profound tension between scholarly efforts to reconstruct history and interpret cultural traditions
and the fragmentary, and often limited, material record. That is to say, scholarship is shaped by a sinuous negotiation around
the historical silences that encompass all of material culture. Historical silences, however, can at times be marginalized
(or at best excluded) by a sensitive configuration of material evidence with oral history.Excluding Archival Silences: Oral History and Historical Absence uses a historically and geographically specific example of oral history to engage in a more generalist discussion of how
oral reflection, especially when shaped by material evidences, can be an especially effective tool for preserving the dynamics
of culture that often remain undocumented. 相似文献

Key points
- Accessibility is often misunderstood as a concept that is niche or of secondary importance.
- Reframing accessibility as improving the overall user experience instantly changes the perspective; accessibility becomes a critical requirement worthy of investment and resources.
- The single most prevalent complaint amongst librarians is the time it takes to get hold of accessible content.
- An accessibility roadmap provides structure and transparency for digital accessibility projects within the organization.
- Publishers' non‐compliance with accessibility standards will increase their risk of sales declines and legal complications over time.
- The SAGE A.C.C.E.S.S.I.B.L.E mnemonic offers suggestions on how to devise a successful accessible publishing programme.

Based on many years of training students in both school and clinical psychology, the authors have formulated some impressions of differences and similarities found in these trainees. While generalizations remain tentative and call for research, the students in each of these disciplines seem to present different patterns in cognitive styles, perceptions of clients, conceptions of professional role, and personality characteristics. In personality, the students in these fields often display differences in need for structure, need for external support, social maturity, and desire for autonomous professional functioning. Differences seem to be related to variations in previous work and educational experiences, and to differences in age, sex and marital status. Implications for quality of service offered and training needs are outlined. 相似文献

The process of assessing students on clinical placements has to date been under‐researched. In particular, while the involvement of subjective judgements in assessing students has been discussed in the literature, there has been no attempt to look for systematic evidence. This paper comprises the first attempt to relate judgement theory to the assessment of vocational education. Preliminary results demonstrate that physiotherapy assessors made subjective judgements of their students, that these contributed to the determination of assessment grades, and that in certain cases these judgements were erroneous. The relationship of these subjective judgements to the awarding of grades via a supposedly objective assessment instrument is not yet known. Given the widespread use of such assessment instruments across different professions, the question raised is whether all observational assessment systems suffer from similar problems. If students are being judged on criteria not included on assessment instruments, perhaps the other criteria being used need to be made more explicit. 相似文献

University policies prohibiting use of mobile devices by medical students during clinical placements are contradicted by regular use by physicians. Consequently, many students use their mobile devices, which can be beneficial for learning but may put patient privacy at risk. This study explores the reasons underlying students' decisions about using mobile devices in clinical settings. We used a mixed-methods sequential explanatory design involving a questionnaire and focus groups. Qualitative data from the questionnaire and focus groups was analysed through thematic analysis. We found students were aware of the risks mobile devices posed to professionalism and medical practice. Despite prohibitions, many made individual decisions to use mobile devices because the benefits outweighed the risks. These students were influenced by an organised, strategic approach to learning and a motivation to comply with the beliefs and behaviours of their medical teams and conform to physicians' directives in order to participate in their community of practice. Many students appear to be transferring everyday use of mobile devices to clinical settings. There is a need to understand and promote aspects of learning that are enhanced by mobile devices in clinical settings, while articulating clear guidelines and boundaries compatible with the professional behaviour expected of students. 相似文献

Exercise testing on motorised treadmills provides valuable information about running performance and metabolism; however, the impact of treadmill type on these tests has not been investigated. This study compared the energy demand of running on two laboratory treadmills: an HP Cosmos (C) and a Quinton (Q) model, with the latter having a 4.5 times stiffer running platform. Twelve experienced runners ran identical bouts on these treadmills at a range of four submaximal velocities (reported data is for the velocity that approximated 75–81% VO2max). The stiffer treadmill elicited higher oxygen consumption (C: 46.7 ± 3.8; Q: 50.1 ± 4.3 ml·kg?1 · min?1), energy expenditure (C: 16.0 ± 2.5; Q: 17.7 ± 2.9 kcal · min?1), carbohydrate oxidation (C: 9.6 ± 3.1; Q: 13.0 ± 3.9 kcal · min?1), heart rate (C: 155 ± 16; Q: 163 ± 16 beats · min?1) and rating of perceived exertion (C: 13.8 ± 1.2; Q: 14.7 ± 1.2), but lower fat oxidation (C: 6.4 ± 2.3; Q: 4.6 ± 2.5 kcal · min?1) (all analysis of variance treadmill comparisons P < 0.01). This study confirms that caution is required when comparing performance and metabolic results between different treadmills and suggests that treadmills will vary in their comparability to over-ground running depending on the running platform stiffness. 相似文献
