Although stylistic variation within social networks has been described in adults, this topic remains under‐researched in children. One question that remains unanswered is the extent to which stylistic variation is the result of automatic alignment or of intentional, pragmatically motivated adjustment. We present an in‐depth sociolinguistic case study of a 10‐year‐old boy, his family and four friends selected according to their place of birth and the duration of their relationship with the boy. Statistical analyses of sociolinguistic variables of French suggest that the child's use of these variants is influenced by pragmatic motivations but not by automatic alignment. La variation stylistique est bien décrite chez l’adulte. Toutefois, sa forme, ses mécanismes et ses fonctions ontogénétiques doivent être davantage étudiés chez l’enfant. Une question concerne notamment le degré auquel cette variation résulte d’un alignement automatique sur les usages de l’interlocuteur ou d’un ajustement intentionnel, fondé sur des motivations pragmatiques. Nous présentons une étude de cas approfondie d’un garçon de dix ans enregistré avec sa famille et quatre amis sélectionnés selon leur lieu de naissance et la durée de la relation amicale qui les lie à l’enfant cible. L’analyse statistique de variables sociolinguistiques du français suggère que cet enfant est capable d’ajustements subtils en fonction de l’identité des interlocuteurs. Plutôt que d’être sous‐tendus par un alignement mimétique sur les usages d’autrui, ces ajustements semblent fondés sur des motivations pragmatiques et identitaires.  相似文献

This paper aims to better understand the relationship between young people's aspirations towards education and jobs, and the context in which they are formed, especially to understand better the role of disadvantaged places in shaping young people's aspirations. Policy makers maintain that disadvantaged areas are associated with low aspirations and there is support for this position from academic work on neighbourhood effects and local labour markets, but evidence is slim. Using a two-stage survey of young people in disadvantaged settings in three British cities, the paper provides new data on the nature of young peoples’ aspirations, how they change during the teenage years, and how they relate to the places where they are growing up. The findings are that aspirations are very high and, overall, they do not appear to be depressed in relation to the jobs available in the labour market either by the neighbourhood context or by young people's perceptions of local labour markets. However, there are significant differences between the pattern of aspirations and how they change over time in the three locations. The paper then challenges assumptions in policy and in the literature that disadvantaged places equal low aspirations and suggests that understanding how aspirations are formed requires needs a nuanced approach to the nexus of class, ethnicity and institutional influences within local areas.  相似文献

This article explores socially withdrawn young Finnish people on an Internet forum who identify with the Japanese hikikomori phenomenon. We aim to overcome the dualism between sociology and psychology found in earlier research by referring to Pierre Bourdieu, who provides insights into how individual choices are constructed in accordance with wider social settings. We focus on the individual level and everyday choices, but we suggest that psychological factors (anxiety, depression) can be seen as properties of social relations rather than as individual states of mind, as young adults have unequal access to valued resources. We scrutinise young people’s specific reasoning related to the social and psychological factors and contingent life events that influence their choice to withdraw. An experience of inadequacy, a feeling of failure and a lack of self-efficacy are common experiences in the data. This indicates that young adults who identify with the hikikomori phenomenon find external society demanding and consider themselves lacking resources such as education, social networks or the personality type that they see as valued in society and as essential to ‘survival’. They also feel that they cannot control their life events, which may mean that they receive little help in their everyday lives.  相似文献

Estimates of the cost of potential disasters, including indirect economic consequences, are an important input in the design of risk management strategies. The adaptive regional input‐output (ARIO) inventory model is a tool to assess indirect disaster losses and to analyze their drivers. It is based on an input‐output structure, but it also (i) explicitly represents production bottlenecks and input scarcity and (ii) introduces inventories as an additional flexibility in the production system. This modeling strategy distinguishes between (i) essential supplies that cannot be stocked (e.g., electricity, water) and whose scarcity can paralyze all economic activity; (ii) essential supplies that can be stocked at least temporarily (e.g., steel, chemicals), whose scarcity creates problems only over the medium term; and (iii) supplies that are not essential in the production process, whose scarcity is problematic only over the long run and are therefore easy to replace with imports. The model is applied to the landfall of Hurricane Katrina in Louisiana and identifies two periods in the disaster aftermath: (1) the first year, during which production bottlenecks are responsible for large output losses; (2) the rest of the reconstruction period, during which bottlenecks are inexistent and output losses lower. This analysis also suggests important research questions and policy options to mitigate disaster‐related output losses.  相似文献

The paper provides empirical evidence on impediments of the emerging social impact investment field in Germany. The study is based on 19 in-depth interviews with social impact investing funds, investment advisors, and social entrepreneurs as investees. It takes an explorative approach because of the nascent stage of research on the subject. By systematically relating the perspectives of the actors involved, the study gives a broad empirical picture on the major challenges for social impact investing in Germany. Results reveal nine critical problem areas we have arranged along three dimensions: financial returns, social returns, and relationships and infrastructure. They comprise investors’ and social entrepreneurs’ practices, institutional settings which are still heavily influenced by peculiarities of the German welfare systems, as well as undeveloped framework conditions in the social investment market. By interpreting the results through a lens of conflicting institutional logics, we further contribute to this research stream by showcasing social impact investing as a core area of friction between the logics of the market and civil society.  相似文献

The activities performed by Canadian workers in some occupations may increase the risk of exposure to infectious diseases such as COVID‐19. This research note explores how occupational exposure risks vary by labor force characteristics using publicly available Canadian data in combination with a data set providing information on the level of physical proximity and frequency of exposure to infections or diseases faced by workers in different occupations. The results show important sociodemographic differences. First, women work in occupations associated with significantly higher average risks of exposure to COVID‐19 than men. This is driven by their overrepresentation in high‐risk broad occupational categories such as health occupations. Second, older workers (65 years or more), a group vulnerable to COVID‐19, appear to work in occupations requiring performing activities characterized by a lower level of physical proximity than their younger colleagues, with minimal differences in the frequency of exposure to diseases or infections. Finally, workers in low‐income occupations are employed in occupations that put them at greater risk of exposure to COVID‐19 than other workers. This is especially the case for women, immigrants, and members of visible minority groups in low‐income occupations. More broadly, this research note provides insights into the health‐related dimension of the literature on occupational tasks and labor market stratification.  相似文献

Aging in the male is accompanied by steroid hormonal decline, and men may develop symptoms associated with hypogonadism. Increased awareness of ‘andropause’ in recent years has led to greater demand for hormonal assessments, resulting in a rising burden for health economics. We conducted a cross-sectional study to define men at risk for hypogonadism, in whom further hormonal investigation should be performed.

We examined 664 blue-collar workers aged 40–60 years at their workplace and determined hormonal status and body mass index (BMI). Men with an abnormal urogenital status and those on medication that might affect endocrine status were excluded from the study. All participants completed the validated Aging Male Symptom (AMS) questionnaire and obtained scores for psychological symptoms, somatovegetative symptoms, and sexual symptoms.

Multiple logistic regression analyses revealed a significantly increased risk (represented by the odds ratio) of psychological symptoms for men with low levels of testosterone and/or bioavailable testosterone (BAT). Increased BMI as well as low testosterone levels and/or low BAT levels raised the risk of somatovegetative symptoms. Each decrease of BAT by 1?ng/ml caused an approximately 1.8-fold increase of the risk (odds ratio?=?1.832, p?=?0.005). Additional independent risk factors were increased age and low luteinizing hormone (LH) level. Men aged 55 years with BMI >?28?kg/m2 and with somatovegetative symptoms and moderate or severe psychological symptoms had a 7.2-fold increase in the risk of a BAT level <?1.5?ng/ml compared to men without these risk factors (p <?0.001). Sensitivity and specificity were 75% and 71%, respectively.

The AMS score combined with age and BMI provides an easy and convenient method to identify men with probable androgen deficiency who require hormonal assessment.  相似文献

The amount of time that children and elderly people spend alone has grown in recent years in Finland. Based on sociocultural theory, children’s development and learning occur in close interaction with the surrounding society, place, and time. The aim of this study is to research children’s experiences of participation in club activities for children and the elderly. The qualitative research data were collected by observing activities and interviewing children. The key factors in supporting children’s participation were common interests in rewarding activities. A warm atmosphere and humor during activities were also found to be important elements in creating positive interactions between children and the elderly.  相似文献
