We study the evolution of topics in economics and their geographical specialization by analyzing 13,233 papers from seven top journals between 1985 and 2012 and their forward citations. The share of U.S. publications declines from 75% to 64% with a corresponding increase of the European share from 12% to 24%. We use topic modeling and document the evolution of the discipline over 27 years. We estimate, with a quasi‐structural model, the citation lag distribution for 18 different topics and three large geographical areas. The modal citation lag is about 6.7 years in the entire sample and 4.8 years for citations from the top 100 journals. We quantify (1) the home bias effect in citations, (2) how it fades away over time, (3) the long lasting impact of U.S. publications vis‐à‐vis other geographical areas, and (4) the higher speed of diffusion and faster obsolescence in the United States.

Glass-cliff research shows that female leaders are preferentially selected in a crisis to signal change and not for their leadership qualifications. In parallel, the management literature urges for agentic “masculine” leadership to turn around organizations in crisis. We hypothesized that, regardless of their gender, agentic leaders should be preferred to communal leaders if leadership qualifications and actual change potential motivate leader selection. Three experimental studies demonstrated that agentic (vs. communal) candidates were perceived to match poorly-performing (vs. strongly-performing) companies. This effect was accounted for by perceptions of agentic candidates' higher suitability, higher task-orientation (versus person-orientation), and higher change potential. We discuss that women face ambiguity as to why they become leaders in crisis contexts: because they are perceived as signaling change, stereotypically linked to their gender, or for their perceived agentic qualities as leaders. In contrast, men become crisis leaders due to their perceived agentic change potential. 相似文献

Current academic literature has proposed contrasting interpretations of the developments of youth religiosity. While some scholars have claimed increasing secularization of younger generations, others have noted the growing importance of religious values in young people's lives. To go beyond this debate, this article explores the restructuring of youth religiosity in Western European countries, characterized by the resilience of religion in secularized societies. With this purpose in mind, the article investigates the under-researched topic of the political activism of highly religious young Catholics and compares the political engagement of two recently established youth organizations: Sens Commun (SC) (rebranded Mouvement Conservateur, MC) in France and the Comunità di Connessioni (CdC) in Italy. Although both SC and CdC were founded by young Catholics, their engagement has followed diverging trajectories. While SC/MC's ideas and politics bear the imprint of conservative Catholicism, CdC's initiatives and values are inspired by social Catholicism. This article claims that the diverging trajectories of SC/MC and CdC are influenced by the long-lasting socio-historical factors that regulated the relations between religion, politics and civil society and the emerging post-secular reconfiguration that can open the way for a renewal of the forms of political engagement of young Catholics. 相似文献

Ten dyads were observed biweekly from 10 to 24 months of infant age while playing together at home with a set of toys. The aim was to examine whether mother–infant coregulation changes over the second year of the infant’s life and whether there are individual differences in that process. Normative trends as well as variability between and within dyads were tested using a multilevel modeling technique. We found that unilateral coregulation, in which only the mother was actively involved in play, largely prevailed at the beginning of the year and then decreased linearly, while symmetrical patterns, implying that the infant was also involved, were for the most part absent at the beginning but then increased rapidly, overtaking unilateral from the middle of the year on and becoming predominant by the end. In particular, symmetrical episodes of shared affect and shared action increased first and then decreased, being replaced by shared language. Variability in data was significant between the dyads, with some dyads advancing toward symmetrical coregulation at an earlier age and more rapidly than the others. It was also significant within the dyads, as the increase in symmetrical coregulation unfolded in a quite irregular manner across the sessions, unlike the decrease in unilateral. Results are discussed with reference to a view of joint attention development as a gradual and complex process. 相似文献

In this paper, we describe the results of a qualitative study conducted with 120 Italian Facebook users to investigate how Facebook enables people to achieve a mutually constitutive intimacy with their own friendship network: a negotiation of intimacy in public through self-disclosure, where the affordances of the platform are useful to elicit significant reactions, validations and demonstrations of affection from others. We observed that, in order to achieve various levels of intimacy on Facebook, people engage in various strategies: Showing rather than telling, Sharing implicit content, Tagging, Expectation of mutual understanding and Liking. These strategies produce a collaborative disclosure that relies on others’ cooperation to maintain the boundaries between private and public space. Based on these premises, we developed a framework of collaborative strategies for managing public intimacy that both systematizes and extends the findings identified in previous studies of intimacy on Facebook. We describe this framework as networked intimacy and we discuss the consequences of it in the light of already existing research on online self-disclosure. 相似文献

The territorial approach of rural development requires taking into account economic, social and environmental features. Therefore, among the goals of the rural development policy the well-being of the target population cannot be disregarded. However, well-being is a multidimensional phenomenon and its measure could be complicated since many indicators (with different scale, units of measure, burden, trends) have to be estimated and analyzed. With a composite indicator which summarizes a bulk of information this concern can be overcome. A multicriteria approach of aggregation is proposed because cardinal aggregation involving in undesirable compensatory property. 相似文献

The non-profit sector is a sizeable and highly dynamic component of economies and societies throughout the world. The expectations placed upon non-profit organizations raise fundamental issues such as the capacity of these organizations to deliver, their accountability to the various constituencies that they serve and their capacity to create value. The effectiveness of these organizations should not be taken for granted, and it is therefore important to understand which factors affect their ability to create value. This paper investigates the relationships between the specific knowledge and experience possessed by board members and foundations’ commitment to pursue high value-added activities, such as the improvement of the performance of grant recipients or social innovation. It uses an empirical analysis to apply statistical techniques to a sample of Italian banking foundations. Our results show that, of the various types of skills and background possessed by board members, the managerial skills of business experts are particularly relevant for value creation by grant-giving foundations. The article therefore contributes to the discussion on the relationship between board skills and organizational outcomes. 相似文献

An evolutionary perspective on CEO-board relations suggests that CEO objectives and interests change over time, and that board roles should shift accordingly, from CEO leadership development during the early stages of CEO time in office toward monitoring during the latest stages. This study examines how two board characteristics, board leadership structure and board diversity, shape innovation investment among Italian firms. Empirical results support the hypothesized effects, suggesting that the board’s effects are contingent upon CEO time in office. 相似文献

Most social protection is provided through contribution-based programmes, which means that protection is usually linked to employment conditions in the formal economy. This article describes the levels, trends and structure of social protection for workers in Latin America, highlighting the relationship between protection and employment conditions. The study is based on a selection of household surveys carried out in various countries in the region: Argentina, Brazil, Bolivia, Chile, Ecuador, Guatemala, Mexico, Nicaragua and Peru. It emphasizes the usefulness of household surveys as sources of information for representative studies on social protection and employment, in spite of the problems of coverage and comparability that they raise. 相似文献
