The dynamics of remittance behaviour among Senegalese men and women in Spain

This article explores the conditions under which Senegalese immigrants in Spain send remittances home, beginning with the premise that remittances are intertwined with migration histories and migrants’ incorporation into host societies. Given the strong gender norms in Senegal, we perform separate analyses for men and women. We use a longitudinal approach to analyse how remittance behaviour is affected by immigrants’ characteristics, their economic integration, and their ties to origin and destination. Our data come from the MAFE and MESE surveys, which were implemented in 2008 and 2011, respectively. The results indicate that remitters constitute a clear majority among Senegalese immigrants in Spain. The Kaplan–Meier analysis shows that they rarely stop remitting once they start doing so, and the multivariate analysis reveals a strong positive association between employment and remittance sending. Although most coefficients in the full model are similar for men and women, some important differences emerge as well.     

Auctioning or assigning an object: some remarkable VCG mechanisms

We construct a variant of the Vickrey auction of a single object where the surplus is split in exogenously fixed shares between the seller and the buyers, up to a margin of error vanishingly exponentially as the number of buyers grows. When the object is the common property of the participants, we can similarly construct VCG mechanisms with a vanishingly small cash transfer to the residual claimant. For any integer q, 3 ≤ q ≤ n, we find the mechanism guaranteeing to each participant a fair share of the qth highest valuation, while minimizing the worst possible ratio of the cash transfer to the efficient surplus. We perform a parallel analysis when the object is undesirable. We compare the cash lost to the largest spread between individual valuations, and obtain the same trade-offs between fairness and the relative loss of surplus.     

Longitudinal analysis of personal networks. The case of Argentinean migrants in Spain

This paper discusses and illustrates various approaches for the longitudinal analysis of personal networks (multilevel analysis, regression analysis, and SIENA). We combined the different types of analyses in a study of the changing personal networks of immigrants. Data were obtained from 25 Argentineans in Spain, who were interviewed twice in a 2-year interval. Qualitative interviews were used to estimate the amount of measurement error and to isolate important predictors. Quantitative analyses showed that the persistence of ties was explained by tie strength, network density, and alters’ country of origin and residence. Furthermore, transitivity appeared to be an important tendency, both for acquiring new contacts and for the relationships among alters. At the network level, immigrants’ networks were remarkably stable in composition and structure despite the high turnover. Clustered graphs have been used to illustrate the results. The results are discussed in light of adaptation to the host society.     

Coordination of teams,meetings, and managerial processes in construction projects: using a lean and complex adaptive mechanism

In a construction project, the ‘production planning and control’ function drives the deployment of construction operations. A reliable function is therefore essential. Currently, this function is supplied using economic/contractual and production processes. This approach, however, disregards the explicit regulation of teams, meetings, and the linkages between the function’s elements. Using Lean Management and Complexity theories, we studied a mechanism to address this issue. Using data from an 18-storey building construction project in a case study, this paper analyses a prototype system for driving the function using their linkages. A questionable behaviour beyond the function’s capability was found. This behaviour involves complex, flexible, and push features, focused on execution, where the linkages driven by teams, meetings and processes cause variation from 10% up to 54% in the failure reasons, the progress, and the reliability. These findings suggest a function driven by its complexity level. These new insights require further study.     

The inclusion of the other in ourselves: reception and comprehension of refugees in Portugal

Abstract

The intensification of different types of migration movements during the last decades is an expression of growing interconnections at the global level. The so called ‘refugee crisis’ is the most visible sign of this intensification. It currently challenges societies to rethink the processes of integrating those fleeing from humanitarian crises and wars. Portuguese civil society has pioneered the creation of a Refugee Support Platform, aimed to address the challenges associated with the arrival of refugee families. Within this platform, an e-learning course was created to help institutions and host families prepare for this task. In the article we first describe this course, focusing our analysis on the relevance of this initiative for institutions, families, and private citizens that wish to welcome refugees in Portugal. We then briefly reflect on the literature pertaining to intercultural dialogue and social tensions. In the final section we analyse the voices of those who attended the course. We conclude with an analysis of the contents of the course modules and the participation of the trainees as a contribution to their self-transformation.     

Psychometric properties and criterion validity of the Perceived Vulnerability to Disease Scale (PVD) in the Spanish population / Propiedades psicométricas y validez de criterio de la escala de Percepción de Vulnerabilidad a la Enfermedad (PVE en población española)

Perceived Vulnerability to Disease may be defined as the beliefs about personal susceptibility to the transmission of infectious diseases and the emotional discomfort associated with the potential disease transmission. To evaluate these beliefs, the Perceived Vulnerability to Disease Scale (PVD) has been used in most studies. The aim of Study 1 was to validate the PVD questionnaire to the Spanish population. The sample was made up of 744 university students from all over Spain. Confirmatory factor analysis revealed that the items on the short version of the questionnaire corresponding to an interrelated two-factor model (perceived infectability and germ aversion) showed the best fit of all the tested models. In Study 2, scales to measure antifat attitudes, disgust and negative attitudes towards AIDS were used to analyse the criterion validity of the PVD questionnaire. The sample was made up of 434 university students. It was found that germ aversion was positively related with antifat attitudes, disgust and negative attitudes towards AIDS. In light of these results, we conclude that the short version of the questionnaire has good psychometric properties and can be used by the scientific community to measure Perceived Vulnerability to Disease.     

When Engagement Meets Politics: Analysis of a Brazilian Public Institution

Perception of organizational politics (POP) is usually associated with counterproductive factors. The reason for this stigma is that generally when employees perceive self-interest actions or backstage manoeuvres, they identify obstacles to their careers. On the other hand, the concept work engagement represents physical, cognitive and emotional factors from its dimensions (vigor, dedication and absorption) that can connect employees to their jobs. This study aimed to investigate the relationship between the dimensions of work engagement and perceptions of organizational politics in a public institution. Data were collected from 847 employees of a public educational institution, followed by a hierarchical cluster analysis to characterize groups with high and low work engagement scores. Multiple linear regressions were performed for each cluster. It was found that in the low engagement group, the three constructs’ dimensions were negatively related to POP. In the high engagement group there was no negative relationship between those two concepts, but a positive association between dedication and perception of politics was found. The results show evidence that highly engaged civil servants do not identify politics as an obstacle to their career development. The study also suggests that POP level is high in public educational institutions.     

Understanding Symbolic Boundaries and Improving Quantitative Analysis of Social Exclusion by Improving the Operationalization of Boundary Work

In survey research, how can we measure actors' judgments concerning who is a member of a particular social group and who is not? How can we measure changes in this process over time? Within the sociology of culture, the operationalization of boundary work, or decisions of group membership, has been relatively overlooked. Similarly, measurement of changes in boundaries has been relatively overlooked as well. An important first step is to better match the operationalization of boundary work with theory. To do so, I argue that survey items concerning decisions of social exclusion measured in the Likert scale can be used. In addition to allowing scholars to compare those who exclude with those who include (often measured as Strongly Agree/Agree vs. Disagree/Strongly Disagree), the Likert scale offers a measurement of boundary strength: how strongly respondents are committed to their exclusionary judgments (Agree vs. Strongly Agree, Disagree vs. Strongly Disagree). A novel element of boundary change can then be measured as variation over time in commitment to exclusionary judgment in time series data. A boundary that has increased in strength would be one for which respondents increase in their emotional commitment to their exclusionary judgment over time.
