Information technology (IT) incidents that make data inaccessible may cause businesses to lose customers, reputation and market position. Previous studies on information management have identified data availability as a key priority, and the literature on disaster recovery and business continuity describes ways of preparing for and avoiding IT incidents. However, no frameworks for information system continuity management (ISCM) have yet been validated. This research draws on a framework for business continuity management, and extends it to the context of information systems. The framework is validated in a survey of IT managers and chief information officers in large private and public organisations operating in Finland. The results suggest that the embeddedness of continuity practices in an organisation has perceived business impacts whereas, in contradiction of previous theory, there is no such direct relation in the case of organisational alertness and preparedness. The theoretical contribution is to validate the ISCM framework statistically. On the practical level, social factors such as committed managers and employees are influential in decreasing negative business impacts. Further research on the embeddedness of continuity practices is called for. 相似文献

This article seeks to add to the growing volume of evidence of a broad, tenacious and visible footballing culture throughout nineteenth-century Britain. It is argued that football persisted among the general population in a variety of forms, none of which required the assistance or involvement of the public schools or public schoolboys to ensure its survival as some historians had previously believed. Indeed, the sheer number of games, evidenced in a variety of forms and a variety of settings, suggests beyond reasonable doubt that most forms of football being played across the country were not formal matches but small-sided games played on church, works' or schools' outings, at rural fetes, galas and celebrations, or as street or casual football, the latter taking place on meadows, fields and greens. Contrary to orthodox historians, these games did survive through mid-century. Importantly, these were predominantly small-sided games and are the ones which are closest to Association football as it was codified in 1863 and hence of most interest to the debate on origins. Common sense then dictates that football can be seen as a cultural continuity, especially as far as the traditions of male youth are concerned, across the nineteenth century. 相似文献

Drawing upon fieldwork conducted with a group of dislocated Tibetan undergraduate students of the neidi ban program in a Han-predominated university, this paper examines the ways in which these students make sense of their worlds. To achieve this, they have actively and engagingly organized a series of symbolically meaningful activities that draw on the symbolic resources from their cultural traditions, their specific educational trajectory, and their anticipation for the future. The paper, nonetheless, also questions in the conclusion how the program can sustain a promising future that is inseparable from the sense of self-worth among the Tibetan students. 相似文献

从语言具有连续性特点的角度,对普遍认为的日语"不规则句式"结构进行了深入的考察,发现了它们与日语存在句之间的连续性特征,并指出具有这种连续性特征的深层原因在于日语的「なる言語」这一特性,即日语具有个体和事件的场所化的特点。 相似文献

Currently there is a large variation in the quality of children's experiences, both across and within primary schools and concerns regarding the quality of physical education (PE) teaching. Significantly, a failure to engage children at this critical time in appropriate high quality PE provision, prior to the transition to secondary education, is likely to result in inadequate development of basic movement competence and motivation to be physically active. Critical to this is the collaboration between primary and secondary PE teachers and ensuring that programmes of study for PE are progressive and provide continuity to promote future lifelong physical fitness. A mixed method design was used employing both focus groups and interviews with primary PE teachers to assess their perceptions of the transition process to secondary school and its impacts on children's physical education. Findings would suggest that primary PE teachers receive little support from their secondary counterparts and are often viewed upon as insignificant in providing initial physical education experiences to young children. 相似文献
