This paper evaluates the dominant perspectives for understanding e-democracy in practice. It argues that although these, on their own, only provide static and partial accounts of the role and implications of e-democracy, nevertheless they should not be disregarded. The paper proposes an integration of their key positions to generate a more rounded and complete account of the role of e-democracy in practice. It suggests that Giddens's Structuration Theory provides a starting point in this direction. A structuration perspective is able to integrate many of the diverse perspectives whilst simultaneously avoiding technological and social determinism by focusing attention on the interplay of social structures and agency in e-democracy practices. This perspective assists in illuminating the underlying institutional arrangements and structures in which e-democracy practices are embedded, as well as the strategies employed by human actors. It focuses attention on structures of signification, domination and legitimation that surround e-democracy practices and also how individuals are both enabled and constrained in these practices. It is argued that more complete and balanced accounts which emerge from such an integrated perspective could assist in developing a more effective e-democracy policy.  相似文献

We explore the determinants of domestic violence in two rural areas of Bangladesh. We found increased education, higher socioeconomic status, non-Muslim religion, and extended family residence to be associated with lower risks of violence. The effects of women's status on violence was found to be highly context-specific. In the more culturally conservative area, higher individual-level women's autonomy and short-term membership in savings and credit groups were both associated with significantly elevated risks of violence, and community-level variables were unrelated to violence. In the less culturally conservative area, in contrast, individual-level women's status indicators were unrelated to the risk of violence, and community-level measures of women's status were associated with significantly lower risks of violence, presumably by reinforcing nascent normative changes in gender relations.  相似文献

The purpose of this research was to construct a short scale to assess the death distress construct, that is, death anxiety, death depression, and death obsession as derivatives from the already existing scales. A sample of 630 volunteer undergraduates responded to scales of death anxiety, death depression, and death obsession. A Pearson correlation matrix was computed using the 51 individual items of the three scales. A forced three-factor principal components analysis with orthogonal varimax rotation was carried out. Eight items with factor loading > 0.5 on each scale was determined. The eight items with highest factor loadings on Factor I were with "Death obsession," whereas the Factors II and III were labeled: "Death anxiety," and "Death depression." Their alpha reliabilities ranged from 0.83 to 0.93, indicating high internal consistency. One week test retest reliability ranged between 0.76 and 0.91, indicating temporal stability. A single high-loaded factor of death distress was disclosed, demonstrating the discriminant validity of the death distress construct and scale. Women obtained a significantly higher mean scores on all three factors. It was concluded that the aforementioned three factors were sufficiently independent to justify their use in assessing partially distinct sub-constructs as sub-components of the generic high-order factor of death distress, with empirical and clinical implications.  相似文献

Associations between marital quality, maternal emotional expressiveness and children's sibling relationships were examined in a sample of 64 seven-year-olds and their mothers. Mothers reported on the quality of their marital relationships, and children rated the quality of their sibling relationships. Mothers and children provided data on maternal emotional expressiveness. Results indicated that marital dissatisfaction was associated with hostile and rivalrous sibling relationships and with maternal negative emotional expressiveness. Mothers' negative emotional expressiveness was correlated with hostile and rivalrous sibling relationships, and maternal positive emotional expressiveness was associated with affectionate sibling relationships. Maternal emotional expressiveness mediated the links between the marital relationship and sibling hostility and rivalry.  相似文献

Neighbor-balanced designs are useful to remove the neighbor effects in experiments where the performance of a treatment is affected by the treatments applied to its adjacent neighbors. In this article, neighbor-balanced designs are constructed in linear blocks of (i) equal sizes and (ii) two different sizes k 1 and k 2.  相似文献

ABSTRACT

We consider the estimation of the conditional cumulative distribution function of a scalar response variable Y given a Hilbertian random variable X when the observations are linked via a single-index structure. We establish the pointwise and the uniform almost complete convergence (with the rate) of the kernel estimate of this model. As an application, we show how our result can be applied in the prediction problem via the conditional median estimate. Also, the choice of the functional index via the cross-validation procedure is also discussed but not attacked.  相似文献

Neighbor designs are useful to neutralize the neighbor effects. In literature, most of the constructed neighbor designs are in circular blocks but linear blocks have more practical application in field experiments. In this article, some infinite series of minimal neighbor designs are constructed in proper linear blocks. There are many situations where minimal neighbor designs cannot be constructed in proper linear blocks. To overcome this problem neighbor designs in improper linear blocks and GN2-designs in proper linear blocks are constructed.  相似文献

Early in the pandemic of coronavirus disease 2019 (COVID-19), face masks were used extensively by the general public in several Asian countries. The lower transmission rate of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in Asian countries compared with Western countries suggested that the wider community use of face masks has the potential to decrease transmission of SARS-CoV-2. A risk assessment model named Susceptible, Exposed, Infectious, Recovered (SEIR) model is used to quantitatively evaluate the potential impact of community face masks on SARS-CoV-2 reproduction number (R0) and peak number of infectious persons. For a simulated population of one million, the model showed a reduction in R0 of 49% and 50% when 60% and 80% of the population wore masks, respectively. Moreover, we present a modified model that considers the effect of mask-wearing after community vaccination. Interestingly mask-wearing still provided a considerable benefit in lowering the number of infectious individuals. The results of this research are expected to help public health officials in making prompt decisions involving resource allocation and crafting legislation.  相似文献
