This paper contributes to e-government research by presenting a review and discussion on how digitalization of public services has affected the interaction between citizens and government. We argue for a conceptualization and critical reflection on the nature of the underlying interaction between citizens and public officials - the public encounter - that digital public services are developed to support. We apply a qualitative and hermeneutic approach and illustrate that digital public services change public encounters concerning when, where, and how interactions occur, what each actor does, and the skills required of them. By relating these changes to emerging digital technologies (e.g. data mining, machine learning, sensor technology, and service automation), we illustrate that while these new technologies carry the potential to further digitalize service provision and fulfill the democratic goals of digital government, authorities can apply the same technology to restrict, control, and surveil citizens. Based on a critical discussion on what digitalization might entail for society, we identify problem areas arising from this development and propose a research agenda for understanding this phenomenon further. We raise questions and ethical concerns regarding accountability and reskilling of citizens and public officials as public service provision becomes citizen self-service. 相似文献

This article examines the intersectionality of law and race to argue that law, in its broadest understanding, has played a pivotal role in the performative constitution of racial subjects. This disciplinary regulation, which has operated to “fix” an individual within a racial status under law, has augmented the production of the individual as a raced subject. An analysis of Rhinelander v. Rhinelander, however, illuminates that a defiance of racial performative dictates can render “race” hidden in plain sight. This rendering represents an escape from the regulatory mechanisms of law, posing a counter‐power that threatens to disturb hegemonic whiteness. 相似文献

The asymptotically distribution-free (ADF) test statistic depends on very mild distributional assumptions and is theoretically superior to many other so-called robust tests available in structural equation modeling. The ADF test, however, often leads to model overrejection even at modest sample sizes. To overcome its poor small-sample performance, a family of robust test statistics obtained by modifying the ADF statistics was recently proposed. This study investigates by simulation the performance of the new modified test statistics. The results revealed that although a few of the test statistics adequately controlled Type I error rates in each of the examined conditions, most performed quite poorly. This result underscores the importance of choosing a modified test statistic that performs well for specific examined conditions. A parametric bootstrap method is proposed for identifying such a best-performing modified test statistic. Through further simulation it is shown that the proposed bootstrap approach performs well. 相似文献

‘Knowledge society’ and ‘knowledge economy’ are current buzzwords in the visions of the future made by nations, regions and federations on a global scale. A concrete outcome of this is the globalisation and intensification of higher education and research. The visions based on a knowledge component should be treated as expressions of an ideology. In this article we use the notion of ‘eduscapes’ and ‘imaginaries’ as analytics for an understanding of such visions as these are expressed by individuals and institutional actors involved in educational landscapes. The argument is made that this notion is less ideological and more apt for an analysis of globalisation of higher education. 相似文献

A research review of e-assessment 总被引：1，自引：0，他引：1
Ulf Stödberg 《Assessment & Evaluation in Higher Education》2012,37(5):591-604
The use of e-assessment in higher education is a relatively new educational practice that has been more frequently studied in recent years. This review aims to summarise some research on e-assessment, providing an overview based on articles from three well-established scientific journals. Focusing on research topics, settings for e-assessment and research methods used in the articles, the review reveals a research field with a broad spectrum of inquiries and approaches. Research of e-assessment practices is often conducted as small-scale studies in which the e-assessment task comprises closed questions such as multiple-choice questions. The article discusses the findings to guide future research and concludes that there is a need for more studies on e-assessment in online courses as well as for longitudinal studies. 相似文献

Lundgren, U. P. 1979. Educational Evaluation. A Basis for, or a Legitimation of, Educational Policy. Scandinavianjoumal of Educational Research 2), 31‐45. The article is written as a basis for a discussion on the function and purpose of educational evaluation. The main standpoint is that different approaches for educational evaluation are presented as scientific improvements, but mirror mainly the objective functions of education in the society and the need within the state apparatus for a scientific legitimation of various political decisions. From that notion, arguments are developed for a wider interpretation of educational evaluation‐based theories on the relation between education, the state apparatus, and the society oriented critical research. 相似文献

Cardiorespiratory fitness (CRF) is associated with health benefits in children, improving cardiac morphology, cardiovascular disease risk factors, and biological outcomes. This study aimed to examine the substitution effects of displaying a fixed duration of sedentary time with a fixed duration of physical activity (PA) at different intensities on children’s CRF. A total of 315 children (136 boys) were assessed (age: 10.6 ± 0.6 years old). Outcomes at baseline and follow-up (16-months) were CRF determined using a maximal cycle test and sedentary time and PA measured with accelerometers. Data were analysed by isotemporal substitution analyses estimating the effect of reallocating 30 min/day of sedentary time by light (LPA), moderate (MPA) and vigorous physical activity (VPA) on CRF. VPA was positively and significantly associated with CRF cross-sectional (β = 0.026, p < 0.001) and prospectively (β = 0.010, p < 0.001). Reallocating 30 min/day of sedentary time into VPA was positively cross-sectionally (β = 0.780, p < 0.001) and prospectively (β = 0.303, p < 0.05) associated with CRF. Conversely, relocating 30-minutes of sedentary time into 30 minutes of LPA and MPA was not associated with CRF. These results suggest that reallocating an equal amount of time from sedentary into VPA is cross-sectional and prospectively associated with a favourable CRF. 相似文献

From finding to making: Jacques Rancière,Richard Rorty,and the antifoundationalist story of progress
Ulf Schulenberg 《Culture, Theory & Critique》2017,58(3):275-293
What is the contemporary significance of the modern antifoundationalist story of progress? By offering a critique of foundationalism and representationalism, pragmatists like John Dewey and Richard Rorty elucidate the far-reaching implications of this question. This article argues that Jacques Rancière’s critique of traditional philosophy and of Louis Althusser’s version of Marxism can be regarded as an important part of the antifoundationalist story of progress. Furthermore, it highlights suggestive affinities (and some differences) between Rorty’s postmetaphysical scenario of a poeticised culture and Rancière’s notion of the aesthetic regime of art. This article seeks to prepare the ground for a comparison between Rancière’s topographical and horizontal critique and Rorty’s pragmatist humanism as nominalist historicism. 相似文献

Top short track speed skaters and their coaches have suspected that starting positions influence finishing positions, especially in the 500 m racing distance. The objective of this study was to examine systematically the influence of starting position on finishing position in 500 m short track speed skating. The data analysed included results from World Cup 500 m races ranging from the 1999-2000 season through to the end of the 2003-2004 season. All 500 m men's and women's races with four skaters starting and finishing (preliminaries, heats, quarter-finals, semi-finals and finals) were included in the data set. The association between starting position and finishing position was examined using Kendall's tau. Results show that for both sexes, there is a significant positive correlation between starting position and finishing position (P<0.001). This effect is generally more pronounced in semi-finals and finals than it is in preliminaries, heats and quarter-finals. Strategies to counter this inequity are proposed, drawing upon similar experiences in other sports. 相似文献

The authors show from two concrete examples that when comparing different subgroups attained from different total groups it is in general impossible to draw any conclusions about the difference between the total groups. That will hold, of course, with the assumption that the subgroups are attained by natural self‐selection instead of random sampling as in experimental design. This rather paradoxical situation depends on differences in the strength of selection. This strength of selection is decided mainly on the one hand by the relative distribution over subgroups, on the other hand by the overlapping of subgroups on the investigated variable. 相似文献
