Digitalization and migration: the role of social media and migrant networks in migration decisions. An exploratory study in Nigeria
No full textPurpose: This paper aims to explore the connectivity between social media use, access to migrant networks, information asymmetry and migration intentions. Design/methodology/approach: The study was conducted using data from individuals living in Nigeria and analysed with a generalized structural equation model, which is rare for this kind of research. Findings: The authors find a dual mediating role of the social media and the migrant networks in facilitating migration, i.e. reducing the threshold cost required to migrate and introducing a bias in terms of information asymmetry. While social media and access to migrant networks directly increase migration intentions, this changes when incomplete information is provided. People who use social media and their migrant networks for information are more likely to have information about destination countries than information on the transit risk. Social implications: The study adds valuable insights for designing awareness campaigns aimed at reducing irregular migration. Originality/value: This study contributes to the understanding of the intersection of migration and digitalizatio
How does international migration impact on rural areas in developing countries? A systematic review
No full textThis study is a systematic review of literature on the impact of international migration on rural areas. We examined this impact on six rural welfare indicators, including labour, livelihood activities, income, food security, land use, and rural development. We selected 44 papers from a pool of 1544 articles published from 2007 to 2018. We found that the impact of international migration on selected indicators varies and are highly context-specific. The results point to the existence of heterogeneity in impacts, capable of creating a space of losers and winners among migrants and non-migrants households. The immediate impact is the loss labour effect, which leads to a process of feminisation of agriculture and the use of child labour. In the intermediate, this trend changes the power relationship in rural areas, briefly increasing the opportunities for the non-migrants household to control land. However, remittance helps the migrant household to move up in the income ladder, improving their food security, enabling the repurchase of land and causing a transition away from agriculture. We submit that international migration from developing countries could create a dynamic process of structural and functional transformations in rural areas, which may ultimately lead to a transition away from agriculture. We provide several policy implications and identified some research gaps for future studies
The Impact of Changes in Regulatory and Market Environment on Sustainability of Wine Producers: A Structural Equation Model
Full text linkWe explore the farmers’ perception of how different external drivers of changes in farming activities could lead to sustainability practices among wine producers. The general assumption is that regulatory and market forces can change the production strategies of wine producers, which could eventually lead to the adoption of sustainability practices. We presented the percentage sustainability practice (PSP) as a novel way of measuring sustainability. We developed a structural equation model (SEM) with 13 hypotheses to test our assumption for the wine supply chain in Tuscany (Italy). Among the market forces, we found that wine growers perceived access to credit to have a significant positive association with sustainability practices. We also found that the perception of change in regulatory instruments such as environmental regulation and Common Agriculture Policy can lead to sustainable practice if they improve access to credit. Our research provides evidence for medium-large scale wine producers, emphasising their role as carriers of innovation in the movement towards sustainable wine production
Understanding Integration Experience and Wellbeing of Economic-Asylum Seekers in Italy: the Case of Nigerian Immigrants
No full textThe literature on migrants’ integration and wellbeing is ample, but the case of economic-asylum seekers in a protracted asylum application system is yet to receive sufficient attention. The economic-asylum seekers are a unique group who migrate with an economic motive but apply for asylum to achieve economic integration in the host country. We use the aspiration-capability framework and a mixed-method approach: participant observation, focus group discussion, and field survey, to study a group of economic-asylum seekers from Nigeria when they were waiting for their asylum decisions in Italy. We find that they evaluate their wellbeing by reflecting on their premigration aspirations, integration constraints, and capabilities. They report lower life satisfaction compared to their satisfaction in Nigeria, and were affected by several barriers including structural, psychological, economic, and social constraints. Our study generally describes what it is like to live in limbo and frustration, with a limited assurance for a better tomorrow. It gives voice to the economic-asylum seekers and contributes to the integration literature by examining their perceptions of integration constraints
International migration, remittance and food security during food crises : the case study of Nigeria
No full textThe paper argues for the need to integrate the linkages between migration, remittances and food crises in the migration-food security literature. Food crises that are exacerbated by erratic climatic changes, violence and other uncertainties are important drivers of international migration. Research on the impact of migration and remittances on food security has grown lately, but it is arguably not comprehensive in its approach. The role of remittances in improving household food security experience during food crises is a vital stream being neglected, and the impact of remittances on food security over a long-term is yet to be studied comprehensively. To fill this gap, we analysed the case study of Nigeria using a World Bank Living Standards dataset, and followed an instrumental variable approach. Our results showed that remittance is valuable in meeting both short and long-term food security, and it is a veritable instrument for meeting household food security during food crises. It is particularly crucial for female-headed households who are more vulnerable to food insecurity. Although it does not significantly improve dietary diversity, households receiving remittances are less likely to adopt unhealthy coping practices such as eating less nutritious food, and less likely to be worried about meeting household food requirements due to lack of money. We conclude that remittances do not only smoothen consumption; it also places households on higher food security equilibrium during food crises
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
