The main goals of e-government are to increase agency efficiency and offer benefits to citizens. These goals have often been addressed as two interplaying outcomes of public e-service development, which are possible to achieve in parallel. This article shows that the two frequently applied stakeholders of e-government (agencies and citizens) are much too extensive and heterogeneous in order to be meaningfully addressed in public e-service conceptualization and development. We conduct a stakeholder centered analysis of a public e-service development and implementation process in order to identify stakeholder groups and discuss how they differ in their perceptions and, consequently, also in their feelings of relevance and need related to the e-service. By adopting a multi-faceted perspective on stakeholders, public e-service development can be analyzed and understood in a way that takes several stakeholder groups into account. Our study contributes with deeper insights about a situation where stakeholder salience changes over time, while some stakeholder groups have low salience during the entire process. The result of conducting a stakeholder centered analysis is that we, by visualizing the stakeholder groups' differences, are better prepared to meet and combine different needs related to a planned e-service. Thus, we argue that a stakeholder centered analysis of expectations and opinions concerning the e-service help to develop e-services possible to succeed in offering both external service and internal efficiency.  相似文献

This study investigated the age of onset of substance use among 536 students with mild academic disabilities and 906 students without academic disabilities, and the extent to which emotional, conduct, and hyperactivity problems explain the differences between these two groups. Using discrete‐time survival analysis, the results of this study showed that students with a mild academic disability were not at higher risk for the onset of daily smoking, and were at a significantly lower risk for the onset of weekly alcohol use and cannabis use. Though students with a mild academic disability displayed higher scores on conduct, emotional, and hyperactivity problems compared with their counterparts without an academic disability, this was not reflected in an increased risk for early onset substance use.  相似文献

Can Children Do Philosophy?   总被引:1,自引:0,他引:1  
Some philosophers claim that young children cannot do philosophy. This paper examines some of those claims, and puts forward arguments against them. Our beliefs that children cannot do philosophy are based on philosophical assumptions about children, their thinking and about philosophy. Many of those assumptions remain unquestioned by critics of Philosophy with Children. My conclusion is that the idea that very young children can do philosophy has not only significant consequences for how we should educate young children, but also for how adults should do philosophy; and that further research is urgently needed.  相似文献

Adolescent loneliness can have detrimental effects on physical and mental health, but there is limited understanding of its antecedents in infancy and childhood. A 20-year longitudinal, multi-informant, and multi-methods study (first data collection in 1998) was conducted to examine mechanisms underlying adolescent loneliness (N = 128, 52% boys, Mage_baseline = 1.23, SD = 0.02, 99% White, recruitment in Dutch urban, healthcare centers). Structural equation modeling showed that high infant behavioral inhibition (BI) was indirectly associated with high loneliness during adolescence via high childhood social withdrawal. This indirect effect was equally strong during early, middle, and late adolescence. Contrary to expectations, infant parenting did not moderate the relation between BI and social withdrawal. The results suggest a developmental cascade with infant BI showing long-lasting indirect effects on adolescent loneliness up to 20 years later via childhood social withdrawal.  相似文献

This study involved four age groups: 13–15-, 23–25-, 33–35-, and 43–45-yr-olds. All adult groups involved persons with university education and persons with low education. Participants (1) solved tasks addressed to spatial, propositional, and social reasoning, (2) evaluated their own performance and the difficulty of the tasks, and (3) answered an inventory probing their self-concept for these reasoning domains and for self-awareness and self-regulation. Structural modeling revealed that performance, self-evaluation, and self-representation are systematically interrelated. Performance in spatial and propositional reasoning stabilized in early adulthood, whereas in social reasoning and self-evaluation, performance improved throughout the age span studied. Educated persons performed better and rated themselves accordingly across all domains. The implications of these findings for the general theory of intelligence and cognitive development after adolescence are discussed. The functional shift model is proposed to account for changes in the relative power of different abilities with increasing age.  相似文献

This study investigated the relationships and interactions between childcare quality (Early Childhood Environmental Rating Scale – Revised edition [ECERS‐R]/Early Childhood Environmental Rating Scale – Extension [ECERS‐E]) and children's social skills (SSRS) in different sociodemographic areas within one Australian city. Multiple regression analysis revealed that some subscales of ECERS‐R and ECERS‐E (language–reasoning, programme structure, space and furnishings, parents and staff, literacy, mathematics, science and environment) predicted the level of children's social skills and the frequency of problem behaviour, with positive and negative effects. Interestingly, although total scores for ECERS‐R and ECERS‐E were not significant predictors of social skills scores, interaction between total ECERS‐R and ECERS‐E scores was a significant predictor. With some qualifications the study provides evidence that both the childcare centre's neighbourhood and the quality of childcare provision are related to children's social skills. The interaction between social/emotional and academic aspects of quality suggests that we need to consider synergistic dimensions in quality in order to optimally enhance social skills in children.  相似文献

First year expectations and experiences: student and teacher perspectives   总被引:2,自引:0,他引:2  
Transitioning from high-school to university can be difficult, and many university teachers feel students are often ill-prepared for the change. To investigate this 233 Humanities and Science students at the University of Adelaide were surveyed 6 months into their first year regarding experiences of teaching and learning at university. 189 students were also surveyed 18 months after commencement, to gain retrospective views of their transition year, as were lecturers and tutors of both groups. Results were compared to similar Orientation Week questionnaires that focused on expectations. Questions included reasons for selecting degrees, quality of teacher feedback and perceived impact of outside commitments. Even though student expectations, student experience, and teacher views differed, remarkable similarities emerged across the two degree programs (Science and Humanities). Our findings thus highlight a call for non-specialised transition programs to meet the needs of first year students and facilitate the transition from secondary to tertiary education. All authors contributed equally to this work.  相似文献

There has been an explosion of mental health literature available on the Internet over the past 5 years, with current estimates placing the number of health related Websites at over 100 000. The scope and depth of each site is unique and this serves to contribute to the difficulty of finding reliable, high‐quality literature. This paper details efforts being made within the UK to provide high quality, evidence‐based mental health literature for patients, clinicians and health policy makers as part of the National electronic Library for Health project.  相似文献

The 1920s was characterised by a struggle over the social acceptance and inclusion of women's track and field disciplines into international organisations. The debate was particularly heated between Alice Milliat, the then president of the Fédération Sportive Féminine Internationale, and the members of the International Athletic Federation and International Olympic Committee. Underlying the debate were differing assumptions about gender ideals and the role of women in society. While Milliat's efforts have been crucial and recognised in developing women's track and field, little research has examined how visual representations of track and field athletes related to gender norms. In this paper, we examine a corpus of professional sports photographs taken during the 1926 Women's Games in Gothenburg to gain understanding of how female athletes' media representations were part of negotiations over gender ideals. Placing the material within the notion of ‘gender dispositive’, our analyses reveal a process of negotiation between the ‘new’ woman ideal that included characteristics such as autonomy and self-control, as well as the mechanisation of women's bodies and traditional notions of femininity.  相似文献
