This article intends to contribute to the increasing body of academic literature on the frontline delivery of activation policies. In line with the broader literature on frontline work, this literature focuses attention on frontline delivery practices and preferences and how these can be explained. Activation work is an interesting case in this context, because activation workers’ jobs designs vary considerably and workers have a diversity of educational backgrounds (including but not limited to social work) in the many countries that have implemented activation policies. This article looks at workers’ preferences rather than actual delivery practices. It analyses how job design and educational background are related to workers’ preferences concerning servicing clients, managing activation workers and spending time on various activation-related activities. Although the findings of the research that are presented in the article show that educational background and job design play only a modest role as antecedents of workers’ preferences, future research into this issue remains interesting. For it may help to increase our insights into the optimal match between what activation aims to achieve and how the provision of activation is organized on the one hand, and workers’ skills/qualifications and job design on the other hand.  相似文献

Previous studies report that early life stress, including maternal pre‐ and postnatal stress, has adverse effects on cognitive development and that these associations might be sex‐specific. However, no studies exist on early life stress and infant executive functioning (EF). The aim of this study was to examine the relationship between maternal pre‐ and postnatal stress and infant EF, and whether these associations are moderated by infant sex. Maternal prenatal depressive, general anxiety, and pregnancy‐specific anxiety symptoms were measured three times, and postnatal depressive and general anxiety symptoms were measured 6 months postpartum. Infant EF was assessed with a modified A‐not‐B task 8 months postpartum (= 214). Maternal postnatal general anxiety predicted poorer EF in girls in comparison with boys. Moreover, there was a trend toward an interaction between prenatal anxiety and infant sex such that prenatal anxiety predicted infant EF differently in girls and in boys. No association was found between depressive symptoms or pregnancy‐specific anxiety symptoms and infant EF. These findings suggest that maternal anxiety may have sex‐specific effects on early EF and that pre‐ and postnatal stress may differently affect infant EF/cognitive development. The implications of these findings and important future directions are discussed.  相似文献

Infants born preterm have higher risks of developing linguistic deficits. Considering that the ability to segment words from fluent speech is crucial for lexical acquisition, Experiment 1 tested the ability of healthy extremely‐to‐late preterm infants to segment monosyllabic words at 6 months of postnatal age. Results establish basic segmentation skills in these infants. While we failed to find an effect of the degree of prematurity, this issue will need further exploration. Future studies will also have to specify the scope of these early segmentation skills, both in terms of the types of words segmented, the cues used to do so, and in terms of possible differences in performance between subgroups of preterm infants (e.g., based on gestational age or medical risks). Lastly, given that the preterm infants tested had a mean maturational age of 4 months, Experiment 2 explored monosyllabic segmentation in full‐term 4‐month olds. Infants succeeded at the task, providing the earliest developmental evidence of word segmentation in full‐term infants. These findings better specify the early trajectory of segmentation abilities in both full‐term and healthy, low‐risk preterm infants and support the proposal that prematurity might have a differential effect on the early acquisition of various linguistic levels.  相似文献

This article presents an ethnographic study of politics of waiting in a post‐Soviet context. While activation has been explored in sociological and anthropological literature as a neo‐liberal governmental technology and its application in post‐socialist context has also been compellingly documented, waiting as a political artefact has only recently been receiving increased scholarly attention. Drawing on ethnographic fieldwork at a state‐run unemployment office in Riga, this article shows how, alongside activation, state welfare policies also produce passivity and waiting. Engaging with the small but developing field of sociological literature on the politics of waiting, I argue that, rather than interpreting it as a clash between ‘neo‐liberal’ and ‘Soviet’ regimes, we should understand the double‐move of activation and imposition of waiting as a key mechanism of neo‐liberal biopolitics. This article thus extends the existing theorizations of the temporal politics of neo‐liberalism.  相似文献

In the economic and social aftermath of the 2008 crisis there has been an important and growing new wave of highly qualified Portuguese emigration comprising scientists. No or very few public policies have been designed to reverse this phenomenon, risking the consequences of brain drain. International literature argues that professional reasons are central to scientists’ decision to migrate, even after the 2008 crisis. Spending some time in a foreign country to study, research, or teach, is perceived as a common step in an individual academic trajectory and an advantage for a successful professional career in academia. It is also encouraged by European Union policies. Twelve individual portraits of Portuguese scientists living in central Europe reveal how important other factors are to the migration decision‐making process. These factors include the economic crisis, student mobility programmes, and the current Portuguese scientific system revision.  相似文献

This article outlines the empirical findings of the first national longitudinal study of almost 1,000 recent immigrants who decided to move to non‐metropolitan Australia. The national survey (2008‐2010) identified that new international immigrants tend to move to rural areas because of the natural beauty, lifestyle and community spirit to be found there, as well as the idyllic image of peacefulness and a relaxing environment associated with these areas. Natural attractors, such as rurality and climate, were important features of the places which, according to the survey, were particularly liked. However, there is tension between the imagined Australian rural ideal and reality, with remoteness, isolation and parochialism being the key features in how the countryside may be misrepresented. The retention of new immigrants in rural places is very strongly related to constructed attractors – the availability and quality of infrastructure, as well as recreational, entertainment and cultural activities.  相似文献

Researchers have documented the consequences of relationship instability for parenting stress but have given little attention to within‐partner relationship instability. In this study, the authors used data from the Fragile Families and Child Wellbeing Study (N = 3,544) to estimate the association between within‐partner relationship instability (known as churning or on‐again/off‐again relationships) and parenting stress. First, they found that by the focal child's 5th birthday about 16% of biological parents experience churning. Second, compared to being stably together with or stably separated from the child's other parent, churning is associated with greater parenting stress for both mothers and fathers. Because parenting stress is the same or higher among churners compared to their counterparts who stably separate, this suggests that, more than a change in partner, relationship instability—whether within or across relationships—is tied to parenting stress.  相似文献

From a social disorganization standpoint, neighborhood residential instability potentially brings negative consequences to parent–child relationship qualities, but family social support and racial/ethnic identity may modify this association. Using data (n = 3,116) from the Project on Human Development in Chicago Neighborhoods, this study examines associations between neighborhood residential instability and parent–child warmth and conflict, whether family social support moderates associations between residential instability and parent–child relationships, and variation by race/ethnicity. Multilevel models reveal that residential instability undermines parent–child relationship qualities, particularly for non‐White individuals. Family support is a protective factor for families in less stable neighborhoods and specifically buffers the association between neighborhood residential instability and reduced parent–child warmth. Among Hispanics, family support mitigates the association between residential instability and heightened parent–child conflict. Findings highlight residential instability as a detriment to parent–child relationships; families in unstable neighborhoods may benefit from family social support.  相似文献
