The psychic costs of migration: evidence from Irish return migrants

Within the economics literature, the ‘psychic costs’ of migration have been incorporated into theoretical models since Sjaastad (J Polit Econ 70:80–93, 1962). However, the existence of such costs has rarely been investigated in empirical papers. In this paper, we look at the psychic costs of migration by using alcohol problems as an indicator. Rather than comparing immigrants and natives, we look at the native-born in a single country and compare those who have lived away for a period of their lives and those who have not. We use data from the first wave of the Irish Longitudinal Study on Ageing which is a large, nationally representative sample of older Irish adults. We find that men who lived away are more likely to have suffered from alcohol problems than men who stayed. For women, we again see a higher incidence of alcohol problems for short-term migrants. However, long-term female migrants are less likely to have suffered from alcohol problems. For these women, it seems that migration provided psychic benefits, and this is consistent with findings from other research which showed how migration provided economic independence to this group. The results remain when we adjust for endogeneity and when we use propensity score matching methods.     

Effect of detection methods on risk estimates of exposure to biosolids-associated human enteric viruses

This study illustrates the effect of virus detection methods on estimates of risks of infection of biosolids-associated viruses for occupational workers and residential population during a hypothetical exposure of biosolids. Five gastroenteritis-associated human enteric viruses--enteroviruses (echovirus-12, enteroviruse types 68-71), adenoviruses, rotaviruses, and noroviruses genotype--I-were considered to represent human enteric viruses for risk estimation purposes. Ingested viral doses were calculated using literature-reported total infectious virus concentrations (based on BGM and A549 cell lines) and genome copies (GCs) in Michigan dewatered and class B biosolids. Cell-line-based infectivity parameters (i.e., ratio of total infectious virus concentration to GCs) were developed for different viruses in biosolids to use GCs for calculating ingested viral dose, addressing the issue of integration of molecular methods with biosolids-based virus risk assessment. Use of virus concentrations from molecular methods (with and without using cell-line-based infectivity parameter) resulted in higher risk estimates than culture methods, indicating the effect of the virus detection method on risk estimates. Further, use of virus concentrations from A549 cell lines resulted in higher risk estimates compared to those from BGM cell lines, suggesting the need for a proper choice of cell lines in determining infectious viral dose. The Monte Carlo uncertainty analyses of estimates for risk of infection due to enteroviruses showed that enteroviruses concentration was the most important parameter influencing risk estimates, indicating the need for reducing associated uncertainty. More work is required to develop cell-line-based infectivity parameters for different virus concentration levels and sample matrix types using a cut-off-based approach.     

Healing components of a bereavement camp: children and adolescents give voice to their experiences

This qualitative study is the follow-up to a quantitative controlled study which showed a decrease in childhood traumatic grief and posttraumatic stress disorder symptoms in parentally bereaved children participating in a bereavement camp. The purpose of this study was to identify the healing components of this camp model. Semi-structured interviews with 19 children and 13 parents/guardians were conducted 3 to 9 months after participation in the bereavement camp. Therapeutic Interventions and Traditional Camp Activities emerged as themes. The themes are discussed in relation to previous research as are limitations of the study and the implications for theory, practice, and future research.     

Is Greece a Rent Seeking Society? A Research on the Relationship Between Entrepreneurship,Trust and Institutions

The paper analyses the various interactions among the institutional and cultural environment and the quality of entrepreneurial activity in Greece. The institutional context and the way in which institutions perform in particular, shape the structure of entrepreneurial incentives. As explicitly demonstrated by Baumol (J Political Econ 98:893–921, 1990) institutions actually channel entrepreneurial talent toward different activities which may be productive, unproductive or destructive. At the same time, informal institutions, i.e. culture and values have proven to be of equal importance for entrepreneurship. Within this context, the paper builds a simple model of rewards’ satisfaction accounting for first, the existence of income externalities, in order to test the hypothesis that individuals care about their relative position, i.e. economic status, and second, for the institutional quality, trust and values pertaining in the society, in order to analyze the possible existence of an underlying ‘social consensus’ that is supportive of rent-seeking behavior in Greece.     

Cognitive-behavioural interventions for adolescents in residential child care in Scotland: an examination of practice and lessons from research

This paper sets out to examine the basis and use of cognitive‐behavioural interventions with adolescents in residential child care. The paper outlines the results of a survey of the use of cognitive‐behavioural interventions in Scotland. The survey indicates that such interventions are used widely in residential schools and secure units in Scotland. The paper then reviews some of the studies relating to cognitive‐behavioural interventions, which appear to be most relevant to residential child care. The review revealed many of the positive outcomes of cognitive‐behavioural interventions. However, there are some cautionary notes highlighted by the survey and the review. These relate to issues about generalization of learning and the meaning of the intervention for the young person and for the staff. The paper discusses the importance of other factors in determining the success of cognitive‐behavioural interventions. These factors include the importance of accurate assessment, the role of staff training and the need to ensure that interventions are always in the best interests of the child.     

On the robustness to outliers of the Student-t process

The theory of Bayesian robustness modeling uses heavy-tailed distributions to resolve conflicts of information by rejecting automatically the outlying information in favor of the other sources of information. In particular, the Student's-t process is a natural alternative to the Gaussian process when the data might carry atypical information. Several works attest to the robustness of the Student $t$ process, however, the studies are mostly guided by intuition and focused mostly on the computational aspects rather than the mathematical properties of the involved distributions. This work uses the theory of regular variation to address the robustness of the Student $t$ process in the context of nonlinear regression, that is, the behavior of the posterior distribution in the presence of outliers in the inputs, in the outputs, or in both sources of information. In all these cases, under certain conditions, it is shown that the posterior distribution tends to a quantity that does not depend on the atypical information, then, for every case, the limiting posterior distribution as the outliers tend to infinity is provided. The impact of outliers on the predictive posterior distribution is also addressed. The theory is illustrated with a few simulated examples.     

Transnational life and cross-border immobility in pandemic times

The COVID-19 pandemic dramatically disrupted and reconfigured the cross-border movements of people. Based on an anthropological study of the experiences of transnational migrants during the pandemic (May 2020–May 2021), this article explores stories of how cross-border immobility impacts transnational life and sense of belonging. The stories reveal the emotional toll of prolonged family separation across geographical distances when loved ones are no longer ‘just one flight away’ and give voice to experiences of being ‘trapped’, ‘stuck’ or ‘stranded’ in a state of transnational limbo. Running through the stories are intensified experiences of foreignness, non-belonging, precariousness and discrimination. Some also felt abandoned by their country of origin as border closures left them ‘locked out’ and ‘blowing in the wind’, fostering an experience akin to exile.
