In this paper I provide a conceptualization of international migration networks, which can be used to identify and integrate the internal components of migration systems, and formalize the relationships in an analytic model of the internal network dynamic. With the use of the operationalized model, and microlevel and macrolevel data for guestworkers in Germany during the period 1970 to 1989, we can empirically test the relative influence of internal network variables versus external forces on the attraction of immigrants over time. The empirical results suggest that—as the system matures—network variables have an increasing impact on the attraction of immigrants, while the impact of economic factors declines. The research is concluded with a series of simulations that further highlight the internal dynamic of international migration systems.

Migration Systems

Chapter 7 explores how translocal livelihoods have contributed to a rise in nationalistic discourse, national communitarian ideology and the ethnically mediated ‘othering’ of certain groups. The chapter begins by exploring the linkages between the domestic garment industry, the union movement and political opposition to the incumbent Cambodia People’s Party, before extending the analysis to explore these themes in relation to Cambodia’s two major international migration systems: those with Thailand and Vietnam. The first of these examines issues of national identity amongst translocal migrants to Thailand in order to interpret the impact of international household and community economies on political conceptions of the state. The second examines the perspectives of translocal migrants between Cambodia and Vietnam, in the context of Cambodia’s recent upsurge in anti-Vietnamese popular sentiment and political discourse. Chapter 7 concludes by drawing together the lessons of these case studies to consider both how mass translocal livelihoods have shaped national discourse and how national narratives of nationhood have contributed to structuring Cambodia’s international diaspora.

PurposeA major policy issue facing leaders in the developing world is whether international migration, through remittances, contributes to the development process in migrant-sending communities or impedes the efficient allocation of labor and human capital at the origin countries. This study examines the impact of remittance inflows on out-farm migration of farm labor toward the nonfarm sector. Specifically, this study shows how international migrant remittances may alter the predictions of out-farm migration models by Harris–Todaro.Design/methodology/approachThe authors use unbalanced panel time-series data on 77 developing countries between 1991 and 2010 within a dynamic panel time-series framework to estimate the impact of remittances on the out-farm migration rate.FindingsThe authors find two competing effects of remittances on out-farm migration of labor in developing countries. First, remittances decelerate the out-farm migration rates by supplementing farm income and consumption expenditures. Second, remittances provide a source of investment in nonfarm activities that increase the rate of migration out of agriculture over time. Combining these effects, on average, our elasticity estimates indicate that a 10% increase in remittances reduces the migration out of agriculture, on average, by 0.5% in developing countries over time.Research limitations/implicationsThe authors findings align with the “developmentalist” or “optimistic” views of international migration. International migration, through remittances, help make the inevitable transition out of the farm sector smoother for developing countries.Originality/valueTo the authors’ knowledge, this is the first study to extend the empirical literature on macro-level determinants of out-farm migration within the Harris–Todaro framework to explicitly account for the impacts of remittances inflows into developing countries that the new economics of labor migration (NELM) theory hypothesizes.

Built-up land sprawl is the most intuitive manifestation and main cause of cultivated land pattern change. Understanding spatiotemporal change and its driving factors in the impact of built-up land sprawl on cultivated landscape eco-security under the urbanization gradient can reveal the nature of cultivated landscape ecological risk caused by urban sprawl and promote the scientific implementation of urban planning and cultivated land protection policies. Taking Yangzhou, a medium-sized city with rapid urbanization, as an example, we used multi-sources data (30 m resolution Landsat images in 1998, 2008, and 2018) to analyze the sprawl intensity and direction of built-up land and cultivated landscape ecological risk areas under the urbanization gradient and the spatiotemporal characteristics of the relationship between them. Further, we employed the boosted regression tree (BRT) model to quantify the effects of geographic, social, and economic factors on the impact of built-up land sprawl on cultivated landscape eco-security under different urbanization gradients. Results showed that built-up land sprawl rate increased first and then decreased from 1998 to 2018, forming the sprawl gradients of no. 1–8, no. 8–16, and no. 16–30 urban circle. Its sprawl direction is mainly 20°–90°, 190°–240°, and 305°–355°, whereas cultivated landscape ecological risk area is a continuous sprawl, and the sprawl gradient and direction of the main risk area are consistent with the built-up land. In 1998–2008, the main areas where built-up land sprawl affects cultivated landscape eco-security are located in no. 1–16 urban circle, 20°–55°. From 2008 to 2018, it was located in no. 16–26 urban circle, 305°–355°. In this process, the influence of geospatial factors decreases gradually over time but increases outwardly with the urbanization gradient. The influence of social factors decreases first with time and then increases with the urbanization gradient outward in space. Economic factors increase with time but decrease with the urbanization gradient. The influence of each factor varies greatly over time and with the urbanization gradient.

Background: A substantial proportion of therapists experience the loss of a patient to suicide at some point during their professional life. Aims: To assess (1) the impact of a patient’s suicide on therapists distress and well-being over time, (2) which factors contribute to the reaction, and (3) which subgroup might need special interventions in the aftermath of suicide. Methods: A 63-item questionnaire was sent to all 185 Psychiatric Clinics at General Hospitals in Germany. The emotional reaction of therapists to patient’s suicide was measured immediately, after 2 weeks, and after 6 months. Results: Three out of ten therapists suffer from severe distress after a patients’ suicide. The item “overall distress” immediately after the suicide predicts emotional reactions and changes in behavior. The emotional responses immediately after the suicide explained 43.5% of the variance of total distress in a regression analysis. Limitations: The retrospective nature of the study is its primary limitation. Conclusions: Our data suggest that identifying the severely distressed subgroup could be done using a visual analog scale for overall distress. As a consequence, more specific and intensified help could be provided to these professionals.

This paper has a two-fold objective: first, to examine the terms on which Pakistan receives aid and whether its debt situation is sustainable, and second, to examine the impact of aid and debt on economic growth. It is found that there is little encouraging that can be said about how the terms on which Pakistan has received aid over time have changed, and its current debt situation is not sustainable. Also reported is the analysis done elsewhere which shows that aid has a negative (Granger) causal impact on GDP, and aid has a robust negative impact on economic growth after controlling for supplyside shocks. We provide various reasons for this negative association.

Background: The ongoing demographical shift is leading to an unprecedented aging of the population. As a consequence, the prevalence of age-related diseases, such as atherosclerosis and its thrombotic complications is set to increase in the near future. Endothelial dysfunction and vascular stiffening characterize arterial aging and set the stage for the development of cardiovascular diseases. Atherosclerotic plaques evolve over time, the extent to which these changes might affect their stability and predispose to sudden complications remains to be determined. Recent advances in imaging technology will allow for longitudinal prospective studies following the progression of plaque burden aimed at better characterizing changes over time associated with plaque stability or rupture. Oxidative stress and inflammation, firmly established driving forces of age-related CV dysfunction, also play an important role in atherosclerotic plaque destabilization and rupture. Several genes involved in lifespan determination are known regulator of redox cellular balance and pre-clinical evidence underlines their pathophysiological roles in age-related cardiovascular dysfunction and atherosclerosis. Objective: The aim of this narrative review is to examine the impact of aging on arterial function and atherosclerotic plaque development. Furthermore, we report how molecular mechanisms of vascular aging might regulate age-related plaque modifications and how this may help to identify novel therapeutic targets to attenuate the increased risk of CV disease in elderly people.
