Complex climate and network effects on internal migration in South Africa revealed by a network model

Climate variability and climate change influence human migration both directly and indirectly through a variety of channels that are controlled by individual and household socioeconomic, cultural, and psychological processes as well as public policies and network effects. Characterizing and predicting migration flows are thus extremely complex and challenging. Among the quantitative methods available for predicting such flows is the widely used gravity model that ignores the network autocorrelation among flows and thus may lead to biased estimation of the climate effects of interest. In this study, we use a network model, the additive and multiplicative effects model for network (AMEN), to investigate the effects of climate variability, migrant networks, and their interactions on South African internal migration. Our results indicate that prior migrant networks have a significant influence on migration and can modify the association between climate variability and migration flows. We also reveal an otherwise obscure difference in responses to these effects between migrants moving to urban and non-urban destinations. With different metrics, we discover diverse drought effects on these migrants; for example, the negative standardized precipitation index (SPI) with a timescale of 12 months affects the non-urban-oriented migrants’ destination choices more than the rainy season rainfall deficit or soil moisture do. Moreover, we find that socioeconomic factors such as the unemployment rate are more significant to urban-oriented migrants, while some unobserved factors, possibly including the abolition of apartheid policies, appear to be more important to non-urban-oriented migrants.

Women on the Move in the New Testament

This article discusses the relation between gender and migration in the New Testament. Six cases of women on the move are presented: Mary, the mother of Jesus; the women in the Jesus movement; three women from the first generation of Christ-believers, Prisca, Lydia and Phoebe; and the unnamed slave woman from Acts 16:16. It is argued that these cases reveal a variety of causes for migration and also depict women who are quite different when it comes to social location and power. The article also discusses the importance of migrant networks in the first century, including religious networks such as the Jewish diaspora. It is argued that women played a key role in the migrant networks presented in New Testament texts.

Organized Immigrant Resources and Aspirations at the City Level of the Host Country – the Case of Casa do Brasil de Lisboa

This article looks at the Brazilian migrant association founded in 1992, functioning in the capital of Portugal, Casa do Brasil de Lisboa. Its origin is connected to the period of the first numerous stream of Brazilians coming to Portugal, the colonizer of their homeland in former times. Knowing that migrant networks are of great value to the process of immigrants’ integration into a host society – and a local community as well – Casa do Brasil de Lisboa is very active in this field. For instance, in partnership with the Lisbon City Council, this association offers guidance on the legalization of stay, and access to public and private services in Portugal. However, a large number of tasks undertaken by Casa do Brasil de Lisboa go far beyond this kind of guidance. Two editions of the project Migrante Participa (Migrant Participates) are a clear illustration of it. Each edition created opportunities to meet, gain knowledge, and share opinions on migratory process issues in the context of Portugal and Lisbon as well, encouraging political participation at the local level, for example. Casa do Brasil de Lisboa is also active in the field of culture, promoting Brazilian artists. What is more, this association is not closed for other nationalities and collaborates with various entities. To be more specific, therefore, the focus of this text is on presenting Casa do Brasil de Lisboa as a dynamic immigrant association working on increasing the level of integration and reducing the phenomenon of individual marginalization within the Lisbon community. As a theoretical framework of this text serves the concept of immigrants’ integration of Rinus Penninx.

Sahelian Transnational Networks and Diasporas

This chapter examines the establishment of Sahelian diasporas in Europe and the United States, their remittances, and the return patterns that have become so important for sending households and communities. Large sums of money are sent by Sahelian migrants to support household budgets that have often come to depend on these remittances. The chapter also addresses the development interventions of hometown associations and other migrant networks that fund community projects and provide social services to their sending communities, and the importance of return migration and its effects on local economies. It examines the sustainability of these vital connections between Sahelian diasporas and their home communities in a context where migration out of the Sahel is increasingly restricted. It concludes with questions about the sustainability of these patterns, given the declining commitment and attachment to place of second- and third-generation migrants.

Push/Pull Factors, Networks and Student Migration from Côte d’Ivoire to France and Switzerland

Since 2011, the Ivorian government has invested heavily in higher education to meet its labour market’s growing demand. In this article, we analyse the drivers of Ivorian student mobility from Côte d’Ivoire to France and Switzerland, highlighting the central role of migrant networks. We focus on the decision-making process and find that migration networks play an important role at every step: from initial aspirations to concrete plans and efforts to study abroad. Using 38 in depth interviews and two focus groups with Ivorian students who aspire to study in France and Switzerland, members of the education board, migration officers, and members of the Ivorian diaspora, we reveal that the functioning of the Ivorian higher education system is a factor of uncertainty for many students who consider that salvation can only come from migration. In addition, social representations linked to foreign diplomas inspire Ivorian students to choose international mobility. Migrant networks further encourage Ivorian students to move abroad because stories from successful migrants sharing their mobility experience are coupled with the provision of key resources to support mobility projects.

Social Capital and Its Effect on Labour Market (Mis)match: Migrants’ Overqualification in Germany

If a person is overqualified in the sense that an employee’s level of training exceeds the job requirements, then some human capital lies idle and cannot be converted into appropriate (monetary and non-monetary) returns. Migrants are particularly at risk of being overqualified in their employment; however, this phenomenon cannot be fully explained by differences in human capital or socio-economic characteristics. This paper examines whether social capital plays a decisive role in migrants’ risk of overqualification in Germany. Using data from the German IAB-SOEP Migration Sample, we analyse the job search process of migrants to determine whether social networks influence their risk of being employed below their acquired educational level. We estimate logistic regression models and find that social capital influences the adequacy of migrants’ jobs: We show that migrants are at a greater risk of overqualification if they use only informal job search strategies such as relying on friends or family members. Moreover, we find that homophilous migrant networks and jobs in employment niches are risk factors for overqualification. We conclude that the combination of informal job search modes and homophilous migrant networks leads to a comparably high risk for migrants of being overqualified in their employment in the German labour market.

Ownership structure and OFDI by EMNES: the moderating effects of international experience and migrant networks

PurposeThis study investigates the effect of ownership structure – ownership concentration and firm ownership – on outward foreign direct investment (OFDI) by emerging market multinational enterprises (EMNEs), and further explores the moderating effects of international experience and migrant networks on this relationship.Design/methodology/approachData of Chinese MNEs listed on Shenzhen and Shanghai stock exchanges between 2005 and 2016 are used. The empirical analysis is based on the negative binomial regression model.FindingsThe empirical results reveal a significant inverted-U relationship between ownership concentration and OFDI by EMNEs. State ownership is found to have a positive effect on OFDI by EMNEs. Both international experience and migrant networks strengthen the inverted-U relationship between ownership concentration and OFDI as well as the positive effect of state ownership on OFDI by EMNEs.Practical implicationsEMNEs need to maintain a moderate ownership concentration when conducting OFDI, and they are supposed to make full use of their own international experience and focus on migrant networks of the host country. Policy-makers in emerging economies need to better create a fair business environment for enterprises.Originality/valueCombining agency theory and the resource-based view, this study integrates ownership structure, firm-level heterogeneous resources – international experience and country-level heterogeneous resources – migration networks into a framework to study OFDI by EMNEs, which expands the scope of research in international business.
