Abstract: E‐learning is being mooted as a cheap and effective way to provide public servants and public‐sector organizations with the continuous learning opportunities required to recruit and retain good employees and improve organizational outcomes. This article draws on the extensive literature on e‐learning and the authors' experience with the development and delivery of e‐learning to examine a number of issues that public‐sector managers should consider before embracing e‐learning. The article begins by sorting out what e‐learning is, what forms it can take and how significant a phenomenon it has become in the private and public sectors in Canada and elsewhere. Emerging Canadian government e‐learning strategies are noted. The authors argue that much existing formal e‐learning material is ineffective and set out criteria for identifying viable e‐learning approaches. The claim that e‐learning provides enhanced access to training is critically examined. The authors also argue that the adoption of e‐learning will radically affect the organization of training and its relationship to the wider organization. Finally, the authors critically examine the issue of whether or not e‐learning is cheaper than face‐to‐face instruction. They contend that e‐learning can reduce training delivery costs in some circumstances but that the costs associated with developing and delivering effective e‐learning will be substantial. Sommaire: On a dit que l'apprentissage en ligne est un moyen efficace et peu coûteux offrant aux fonctionnaires des possibilités de formation continue qui permettront aux organismes du secteur public de recruter et de retenir du personnel qualifié et ainsi d'améliorer leurs résultats organisationnels. Cet article repose sur la documentation concernant l'apprentissage en ligne et l'expérience des auteurs en matière d'élaboration et de prestation de cette méthode d'enseignement afin d'examiner un certain nombre de questions que les gestionnaires du secteur public devraient étudier avant de les adopter. L'article commence par expliquer l'apprentissage en ligne sous ses différentes formes et l'importance de ce phénomène dans les secteurs privé et public au Canada et ailleurs. Les nouvelles stratégies d'apprentissage en ligne du gouvemement canadien sont mentionnées. Les auteurs affirment qu'une grande partie de la documentation officielle sur la question est inefficace et ils présentent des critères pour determiner les méthodes d'apprentissage en ligne qui ont des chances de réussir en matière de formation. Ils examinent d'un œil critique si cette méthode d'enseignement foumit en fait un meilleur accès è la formation. L'article laisse éggalement entendre que l'adoption de l'apprentissage en ligne transformera radicalement la planification de la formation et ses relations avec l'organisation plus vaste. Enfin, les auteurs examinent attentivement la question de savoir si oui ou non l'apprentissage en ligne est moins coûteux que l'enseignement en personne. Ils soutiennent que cette méhode peut permettre de réduire les coûts de prestation de la formation dans certaines circonstances mais que les coûts associés à l'élaboration et à la prestation de l'apprentissage en ligne efficace seront considérables.  相似文献

The field of Third World studies is thought once again to be in a state of crisis, thanks largely to disillusionment with the once-dominant dependency “paradigm.” Amidst renewed interest in developmentalism and the clamor for an alternative to dependency, this article argues, first, that the major achievements of dependency theory remain largely unrecognized because the approach has been so frequently misrepresented or misunderstood. Whatever the ultimate status of dependency’s theoretical claims, it contains elements of a countermodernist attitude which ought to be retained in any new approach to the study of Third World development. Second, the article argues that, despite these accomplishments, dependency remains trapped, along with developmentalism, within a modernist discourse which relies on the principles of nineteenth century liberal philosophy; that it treats the individual nation-state in the Third World as the sovereign subject of development; and that it accepts the Western model of national autonomy with growth as the appropriate one to emulate. The final section of the article discusses the efforts of a number of scholars to ground knowledge in local histories and experiences rather than building theory through the use of general conceptual categories and Western assumptions. Although these ideas currently remain on the margins of Third World studies, it is to be hoped that dependency’s loss of intellectual hegemony has at least opened up a space for them to be taken seriously, in the same way that dependency was itself taken seriously in the late 1960s.

Although a relatively high percentage of Australian adolescents experience mental health problems, many disturbed adolescents do not receive the help they require, and only a small proportion of adolescents seek professional psychological help. The present study examined adolescents' willingness to seek help and investigated factors that promote and prevent adolescents from seeking help for a mental illness from both formal and informal sources. Secondary school students (254 in number) from schools in Brisbane, Australia completed a questionnaire that examined the relationship between demographic and psychological variables, attitudes toward mental illness, and willingness to seek help for a mental illness. Results suggest that adolescents with greater adaptive functioning, fewer perceived barriers to help seeking, and higher psychological distress were more willing to seek help from formal and informal sources for a mental illness. Greater social support also predicted willingness to seek help from informal sources. Although attitudes toward mental illness did not influence willingness to seek help, less stigmatising attitudes were related to higher knowledge of mental illness, being female, and higher levels of social support. Implications for the present study focus on enhancing the ability of mental health interventions to increase adolescents' willingness to seek psychological help.Received PhD from The University of Queensland  相似文献

The English High Court recently refused to grant an injunction to restrain The Times newspaper from publishing the identity of an anonymous political blogger (The author of a blog v Times Newspapers Limited [2009] EWHC 1358 (QB)). The facts of the case were unusual: there was no clearly unlawful behaviour by the blogger, who was also a police officer highly critical of political figures and policies. There was also no relationship between the blogger and the journalist who deduced the blogger's identity; the court therefore focussed on the tort of misuse of private information and countervailing public interests, such as freedom of expression. This article describes the approach of the court and considers the earlier case of Mahmood v Galloway ([2006] EWHC 1286 (QB)) concerning an undercover journalist's attempt to prevent publication of photographs showing what he looked like. It also discusses whether data protection law could have a role to play in future cases concerning attempts to preserve an online author's anonymity. The conclusion of the article is that this case does not spell the end of all anonymous blogging.  相似文献

Objectives

Decades of empirical research demonstrate that crime is concentrated at a range of spatial scales, including street segments. Further, the degree of clustering at particular geographic units remains noticeably stable and consistent; a finding that Weisburd (Criminology 53:133–157, 2015) has recently termed the ‘law of crime concentration at places’. Such findings suggest that the future locations of crime should—to some extent at least—be predictable. To date, methods of forecasting where crime is most likely to next occur have focused either on area-level or grid-based predictions. No studies of which we are aware have developed and tested the accuracy of methods for predicting the future risk of crime at the street segment level. This is surprising given that it is at this level of place that many crimes are committed and policing resources are deployed.

Methods

Using data for property crimes for a large UK metropolitan police force area, we introduce and calibrate a network-based version of prospective crime mapping [e.g. Bowers et al. (Br J Criminol 44:641–658, 2004)], and compare its performance against grid-based alternatives. We also examine how measures of predictive accuracy can be translated to the network context, and show how differences in performance between the two cases can be quantified and tested.

Results

Findings demonstrate that the calibrated network-based model substantially outperforms a grid-based alternative in terms of predictive accuracy, with, for example, approximately 20 % more crime identified at a coverage level of 5 %. The improvement in accuracy is highly statistically significant at all coverage levels tested (from 1 to 10 %).

Conclusions

This study suggests that, for property crime at least, network-based methods of crime forecasting are likely to outperform grid-based alternatives, and hence should be used in operational policing. More sophisticated variations of the model tested are possible and should be developed and tested in future research.

To redress the scourge of violent extremism, an array of policies, programs, and practices have been implemented. Yet, these initiatives could sometimes conflict with the preferences of individuals who may be susceptible to radicalization. To illustrate, some initiatives might challenge the values of these individuals. The degree to which these individuals feel significant or important might thus decrease—a decrease that has been shown to rouse the pursuit of violent radicalization. To prevent this complication, two studies were designed to uncover programs, policies, or practices that align to the preferences of people who may be more susceptible than average to violent radicalization. In Study 1, three individuals who had been charged with crimes related to terrorism, but had since relinquished extremism, were asked to suggest initiatives they feel could prevent violent radicalization in Australian Muslims. Similarly, in the second study, young Australian Muslim adults who rejected extremist ideologies were asked the same question. The participants advocated initiatives that foster tolerance towards diverse perspectives, inspire individuals to trust their values and intuition, encourage civic engagement, improve the credibility of imams, and enable people to derive strength from their community. A review of previous literature indicates that many of these initiatives might not only resonate with the preferences of individuals who may be vulnerable to violent extremism but could also foster a sense of significance and meaning in life—an experience that tends to prevent radicalization.  相似文献
