IT project portfolio management (IT PPM) has evolved into a significant area of research interest, but we know little about IT PPM practices in public sector organizations. Therefore this article investigates decision-making processes in the IT PPM practices of local governments, and discusses how these practices match the normative advice proposed by the IT PPM literature. We rely on decision-making theories together with case-studies of four Danish local governments. We find that politics, intuition and coincidence play a crucial role in IT PPM decision-making, while technical rationality (as proposed by the IT PPM literature) plays a minor role. Our account also reveals how the decision-making practices create IT portfolio problems and in some aspects is considered to have a negative impact on the outcome of e-government investments. Our analysis and previous research into decision-making allows us to argue that implementing textbook-IT PPM is difficult because it relies on decision-making ideals that are incompatible with organizational contexts and individual behavior in these organizations. Instead of radically changing decision-making styles, the organizations might be better off improving IT PPM practice within the boundaries of their existing decision-making styles, and the IT PPM literature might improve support for practitioners by incorporating other decision-making styles besides technical rationality. 相似文献

Participatory media are commonly used in today's society for a variety of purposes. The credibility associated with these media is sometimes contested, and their acceptance into school practices has been debated. Focus group interviews with teachers and librarians in upper secondary schools in Sweden are used to investigate conceptions and experiences of activities involving the critical evaluation of participatory media, with a particular focus on Wikipedia. Three themes are addressed. The first concerns how the teaching of the critical evaluation of sources is organized and comanaged between teachers and librarians. The second describes educators' experiences of print versus digital media, and their worry because students have problems negotiating the information architecture of print media. The third theme deals with conceptions of the credibility of Wikipedia. Four conceptions of credibility are identified: credibility is associated with the control and stability of a source; it is considered to be strengthened when several sources support a claim; it is viewed as situational and partial, rather than absolute; and it is associated with a multiplicity of voices and democratic forms of production. These findings may be used to inform educational activities around credibility and authority in schools by raising self-awareness among educators of various ways to talk about the credibility of sources with both colleagues and students. 相似文献

In this study, we investigate the role of physicality in the professional identities of physical education (PE) student teachers. Twenty PE student teachers participated in semi-structured interviews during their final teaching practice. Data were analysed using qualitative thematic analysis and typologies. The results showed substantial diversity in the student teachers’ conceptions of physicality and the ways these conceptions were embedded in their developing professional identities. The results also brought to light criticism directed at traditional notions of the body and physicality in PE and PE teacher education (PETE). We suggest that conceptions of the body and physicality represent a central element of PE teachers’ professional identity. The results also indicate a relationship between conceptions of physicality and pedagogies implemented in the future. Time and place for student teachers to discuss body-related matters should be provided in PETE. 相似文献

The assessment of literacy continues to be the focus of debate. Attention has been given to textual features of students' writing, such as vocabulary, grammar and generic structures. We demonstrate how students' success in school is also dependent on their enactment of the category 'child'. We examine the micro-sociological issue of how students and a teacher interpret and deploy practices appropriate to their status as 'child-student' and 'adult-teacher'. Drawing on work that examines the day-to-day, moment-by-moment enactment of institutional and folk theories of the 'child', we interrogate classroom talk and students' writing for the versions of the 'child' constructed there, the manner in which suppositions about the nature of childhood are enacted, and the implications of normative presumptions about the nature of the 'child' for students' assessment. 相似文献

This paper investigates the effect of within-country and across-country inequalities on firms’ FDI performance, and finds drivers of success in an advanced host economy (the USA) differ for firms from developed compared to developing countries. Returns to FDI for firms from developed countries are significantly correlated with home countries’ level of economic development. In contrast, successful developing-country firms are from countries with lower within-country inequality, and reflect the industrial structure associated with developing countries: They are concentrated in scale-intensive industries and benefit especially from capital investment. The findings suggest that FDI reflects rather than disrupts unevenness in knowledge bases globally. 相似文献

The aim of the study was to investigate prospective relationships between reading and writing performance during the first grade of primary school. The data was collected from 83 Finnish‐speaking children who were examined four times on reading, spelling, and productive writing skills during the first grade. At the beginning of the school year, they were also tested on initial reading skill. The results showed that reading and spelling manifested a reciprocal relationship during the first semester: reading performance increased subsequent spelling proficiency, and spelling skills enhanced subsequent reading. Later on, however, reading predicted spelling in a less reciprocal association. In turn, productivity of writing predicted subsequent reading performance during the first grade although the reverse was not true. The results suggest that it may be important to emphasize the support which compositional writing may offer to the development of reading. 相似文献
