While it has often been suggested that information and communication technologies (ICTs) provide an important means of increasing citizen participation (which is at the core of democratic government), few commentators have expected non-democracies to create online environments in which citizens can take an active part in political processes. In recent years, however, some non-democracies have begun to outperform countries with long-standing democratic traditions in terms of e-participation development. According to the 2010 United Nations (UN) e-government survey, Bahrain outranks France, Kazakhstan beats Sweden and Malaysia ranks higher than Germany. This article sets out to understand the recent rise of e-participation initiatives in non-democracies. Drawing on comparative longitudinal data from the UN e-government surveys, we tested the assertion that international drivers of change are competing with the dominant focus on domestic factors, especially in the non-democratic world, and are influencing the patterns of reform. The empirical analysis demonstrated important differences between the drivers of change in democratic and non-democratic countries and found economic globalization to be the strongest predictor of e-participation initiatives in non-democratic countries. In conclusion, we argue that economic globalization alters the context of e-participation and necessitates a re-examination of many of its premises and tenets. 相似文献

Cadaver-specific postmortem computed tomography (PMCT) has become an integral part in anatomy teaching at several universities. Recently, the feasibility of contrast-enhanced (CE)-PMCT has been demonstrated. The purpose of this study was to identify particular strengths and weaknesses of both non-enhanced and contrast-enhanced PMCT compared to conventional cadaver dissection. First, the students’ perception of the learning effectiveness of the three different modalities have been assessed using a 34-item survey (five-point Likert scale) covering all anatomy course modules. Results were compared using the nonparametric Friedman Test. Second, the most frequent artifacts in cadaver CT scans, were systematically analyzed in 122 PMCT and 31 CE-PMCT data sets to quantify method-related limitations and characteristics. Perfusion quality was assessed in 57 vascular segments (38 arterial and 19 venous). The survey was answered by n = 257/320 (80.3%) students. Increased learning benefits of PMCT/ CE-PMCT compared to cadaver dissection were found in osteology (2/3 categories, P < 0.001), head and neck (2/5 categories, P < 0.01), and brain anatomy (3/3 categories, P < 0.01). Contrast-enhanced-PMCT was perceived particularly useful in learning vascular anatomy (10/10 categories, P < 0.01). Cadaver dissection received significantly higher scores compared to PMCT and CE-PMCT in all categories of the abdomen and thorax (7/7 categories, P < 0.001), as well as the majority of muscular anatomy (5/6 categories, P < 0.001). Frequent postmortem artifacts (total n = 28, native-phase n = 21, contrast injection-related n = 7) were identified and assessed. The results of this work contribute to the understanding of the value of integrating cadaver-specific PMCT in anatomy teaching. 相似文献

This experience sampling study examined whether autonomy-supportive and psychologically controlling interactions with parents are intertwined with adolescents' momentary affect. For 7 days (in 2020), 143 adolescents (Mage = 15.82; SDage = 1.75; 64% girls; 95% European, 1% African, 3% unknown) reported 5 or 6 times a day how they felt and how interactions with parents were experienced. Preregistered dynamic structural equation models on 1439 (including 532 adjacent) parent–adolescent interactions revealed significant within-family associations: Adolescents experienced more positive affect during and following autonomy-supportive interactions, and vice versa. Adolescents felt more negative affect during and 3 h before psychologically controlling interactions. Between-family associations showed significant linkages between parenting and affect. These findings show that a moment of autonomy support can alter adolescents' everyday well-being. 相似文献
