Peer problems are a stressor for many early adolescents, and simple cost‐effective tools for managing peer stress are needed. Expressive writing (EW) may be one such tool. With a sample of middle school children aged 12–14 years (n = 119; 53% males), this research evaluates whether cognitively oriented expressive writing (CEW), which focuses more on psychological self‐distancing, improves personal well‐being better than traditional EW, which focuses more on emotional disclosure. CEW—compared with EW—slightly enhanced long‐term social adjustment for the entire sample, and increased positive affect for those early adolescents that reported more peer problems at baseline. These findings suggest that structured writing instructions with early adolescents may be key to improvements. 相似文献

This article underscores the increasing attention devoted to the concept of prosumption in the social sciences, outlines its historical evolution as a phenomenon, and highlights the emergence of a vivid debate about its beneficial or harmful consequences for individuals. It also unveils the importance of the settings in which prosumptive practices are investigated in contributing to the understanding of prosumption as an exploitative or empowering phenomenon. Drawing on the ever‐expanding literature on the topic, 5 main types of prosumption (infra) are presented and their linkage with pessimistic and optimistic analytical and rhetorical strategies underlined. 相似文献

The growing desire to make the urban environment more sustainable from an ecological point of view has stimulated research
on the architectural and agronomic aspects of green roofs. The practical realisation of green roofs, is however limited by
economic and ecological issues. More specifically, water availability is the most limiting factor, and is likely to be ever
more so in the future in the light of climate change. For this reason, we evaluated the agronomic performance of several xerophytes
in a simulated dry green roof. Seeds of 20 species were collected in typically dry habitats (abandoned quarries, rocky soils,
dunes, etc.) and studied in the laboratory for germination ecology. In cases of strong dormancy, methods were tested to stimulate
germination and their germination ecology was studied. The resulting seedlings were transplanted in spring 2008 in two green
roof types that differ in substrate depth (150 and 200 mm) made up of lapil, pumice, zeolites and peat, resting on a drainage
layer of hydroperlite. Temperature and humidity in the substrate and drainage layer were measured during the whole test period.
Survival of the seedlings in both substrate depths was almost 100%, favoured by a rainy spring. Most of the tested species
showed an excellent performance during the hot and dry summer months in terms of survival rates, growth, and vegetation cover
dynamics, notwithstanding the difficult ecological conditions (temperatures around 50°C; hydric potential Ψ -15 bars). Furthermore,
most of the species had a long flowering stage in the first year of growth. Plants in the green roof with the deeper substrate
depth produced, for most of the tested taxa, a significantly higher vegetation cover and growth compared to when they were
placed in the 150 mm substrate. The results of this study show that some Mediterranean xerophytes have biological characteristics
suitable for their use in dry green roofs, although an irrigation system for emergency use seems advisable. To conclude, further
research should focus on long term evaluation of green roof vegetation in terms of plant survival and flowering dynamics. 相似文献

This article contributes to debates on identification, home and belonging by focusing on EU children in Brexit times.1 The article combines attention to the emotional and affective side of integration with a focus on the effects of the discursive practices of the state on these processes. The article explores how Italian children and their parents navigate the increasingly neo-assimilationist pressures in Britain. Specifically, it looks at children's ways of accommodating their parents’ values of mobility, multilingualism and transnationalism with the revived nationalist logic now dominant. The article argues for renewed scrutiny into the role of public discourses on migrants’ experiences, which illuminate the redrawing of the boundaries between inclusion and exclusion at moments of crisis. 相似文献

Consider a linear regression model with regression parameter β=(β1,…,βp) and independent normal errors. Suppose the parameter of interest is θ=aTβ, where a is specified. Define the s-dimensional parameter vector τ=CTβ−t, where C and t are specified. Suppose that we carry out a preliminary F test of the null hypothesis H0:τ=0 against the alternative hypothesis H1:τ≠0. It is common statistical practice to then construct a confidence interval for θ with nominal coverage 1−α, using the same data, based on the assumption that the selected model had been given to us a priori (as the true model). We call this the naive 1−α confidence interval for θ. This assumption is false and it may lead to this confidence interval having minimum coverage probability far below 1−α, making it completely inadequate. We provide a new elegant method for computing the minimum coverage probability of this naive confidence interval, that works well irrespective of how large s is. A very important practical application of this method is to the analysis of covariance. In this context, τ can be defined so that H0 expresses the hypothesis of “parallelism”. Applied statisticians commonly recommend carrying out a preliminary F test of this hypothesis. We illustrate the application of our method with a real-life analysis of covariance data set and a preliminary F test for “parallelism”. We show that the naive 0.95 confidence interval has minimum coverage probability 0.0846, showing that it is completely inadequate. 相似文献

This paper contributes to the on-going debate about the relevance of the purchasing function for the firm value creation. We empirically examine the role of the purchasing function in improving business performance through an international survey based on 653 responses. Results suggest that purchasing practices related to spend rationalisation have a positive impact on the overall business performance, whereas supplier development & integration and sustainable purchasing have not. Moreover, the purchasing recognition by top managers and other organisational units emerge as a powerful antecedent of all purchasing practices. Instead, pure formal authority provided by the position in the organisation chart (i.e. the report level) does not have any influence on purchasing practices adoption. 相似文献

Moral exclusion is defined as viewing others as lying beyond the boundary within which moral values and rules of justice apply. In contrast, the process of moral inclusion involves the extension of social justice to several social groups. Thus, both moral inclusion and exclusion are a pivotal dimension in the study of social inequalities. Although the concept of moral inclusion/exclusion has a history of more than 20 years, research still lacks accurate instruments for measuring it. In this article, a first version of a scale that measures moral inclusion/exclusion was constructed and validated. The good reliability and correlation indexes found across the samples suggest that MIEG is a good measure for tapping into moral exclusion/inclusion symptoms. 相似文献
