This article presents a review of 20 tests designed for assessing the academic English listening skill of second or foreign language learners. The available test information has been systematically condensed in purpose, listening construct, task characteristics, and validity evidence. It was found that most of the tests were developed for proficiency and placement purposes in academic contexts, with few of the tests serving for making workplace decisions. Also, global, local, and inferential skills constitute the construct in most listening comprehension tests. A practical approach for justifying the uses of these tests for different stakeholders is discussed. This review is a valuable resource for educators, administrators, test developers, and researchers looking for a comprehensive analysis of existing English tests that assess listening comprehension in second or foreign language learners. 相似文献

The current study examined the role of hypothalamic‐pituitary‐adrenal reactivity (a physiological indicator of stress) in early infancy as a mediator of the relationship between maternal postpartum depression and toddler behavior problems. Participants were 137 at‐risk mothers and their children participating in a longitudinal study of intergenerational transmission of risk. Mothers’ depression was measured five times during the infants’ first 18 months. Infant cortisol was collected during a social stressor (the still‐face paradigm) when infants were 6 months old, and mothers reported on toddlers’ internalizing and externalizing symptoms at 18 months. Among this sample of high‐risk mother–infant dyads, early postpartum depression predicted atypical infant cortisol reactivity at 6 months, which mediated the effect of maternal depression on increased toddler behavior problems. Clinical implications are discussed. 相似文献

Multinomial logit (also termed multi-logit) models permit the analysis of the statistical relation between a categorical response variable and a set of explicative variables (called covariates or regressors). Although multinomial logit is widely used in both the social and economic sciences, the interpretation of regression coefficients may be tricky, as the effect of covariates on the probability distribution of the response variable is nonconstant and difficult to quantify. The ternary plots illustrated in this article aim at facilitating the interpretation of regression coefficients and permit the effect of covariates (either singularly or jointly considered) on the probability distribution of the dependent variable to be quantified. Ternary plots can be drawn both for ordered and for unordered categorical dependent variables, when the number of possible outcomes equals three (trinomial response variable); these plots allow not only to represent the covariate effects over the whole parameter space of the dependent variable but also to compare the covariate effects of any given individual profile. The method is illustrated and discussed through analysis of a dataset concerning the transition of master’s graduates of the University of Trento (Italy) from university to employment. 相似文献

International coopetition has rarely been studied in relation to innovation. Further exploration of effects of international coopetition, i.e. the pursuit of simultaneous cooperation and competition, on a firm’s innovation performance is especially important as such a relationship is challenging with a high propensity to fail. This observation formed the point of departure for this study, which aims to increase the understanding of the effects of international coopetition on firm innovativeness and how these effects are conditioned on the magnitude of the organizational adjustments a firm introduces. We use an unbalanced panel of 9839 firms that participated in four waves of the Swedish Community Innovation Survey between 2008 and 2014 as our empirical base. We illustrate that firms that cooperate with competitors internationally are more likely to exhibit higher propensity to introduce radical innovations, yet this effect is conditioned upon the magnitude of organizational adjustments. Overall, our study contributes to the understanding of the implications of international coopetition and what a firm needs to benefit from it. 相似文献

ABSTRACTCompared to racist and ethnicist discourses, literature on sexist discourses – both off and on-line – as hate speech is relatively underinvestigated. This is partly due to the tendency to minimise accusations of sexism and to reframe misogyny as ‘acceptable’ by constructing it as a form of humour. We decided to focus on slut-shaming, one of the most virulent forms of hate speech, which has always existed but was boosted by social media, becoming a stable low-cost ingredient of today’s rape culture. We propose to consider online slut-shaming as a form of ‘technology-facilitated sexual violence’, where digital technologies are used to facilitate both virtual and face-to-face sexually based harms. According to feminist analysis of sexual violence, this would be a matter of power rather than sex: sex would be the weapon, not the motive. We have tested this research hypothesis by focusing on the Italian reception of the MeToo campaign, triggered by Asia Argento’s denunciation. More specifically, two Different Twitter corpora produced within the same five months period were examined by means of a quantitative and a qualitative methodology. 相似文献

ABSTRACTOne overarching question in scholarly methodological discussions on qualitative comparative approaches concerns how it is possible to compare and generalise deep insider knowledge across (nationally) specific contexts. The aim of this article is to propose a research strategy that both facilitates the comparison and theorisation of such knowledge across nations and limits the risks of reproducing naturalised national ‘truths’. The strategy is developed within a feminist, cross-national, qualitative comparative analysis of how European countries addressed military deaths in connection with the ISAF mission in Afghanistan. The article underlines the importance of collective analytical work and of strategies that allow continuous movement between insider and outsider positions throughout the research process. A number of analytical strategies are presented: collective project design, alternating between analytical closeness and distance, and de-familiarising writing practices. 相似文献

ABSTRACT There is a dearth of studies on age-related patterns of political activism in Malaysia, specifically on young people’s patterns of political participation relative to their elders, and in relation to the rich literature that has developed in Western democracies. By analysing survey data from Wave 6 (2010–2014) of the World Values Surveys (WVS), this study aims to investigate the differences in political engagement between younger and older people in Malaysia, including new repertoires outside the mainstream politics, by addressing the question of whether young Malaysians are more active in political activities compared to older groups. The findings conform to the expected patterns in the literature that young people are less likely to participate in conventional political activities than their respective elders. However, we find no significant differences for unconventional political participation. The study further shows that demographic indicators such as the levels of education, gender and ethnic group belonging do not appear to be linked to the age gap between youth and their elders in political activism. As such, the study provides evidence that young people in Malaysia are less likely to be politically active than their elders and that this is not clearly attributable to the socio-demographic factors analysed. 相似文献
