Multiple Criteria Hierarchy Process with ELECTRE and PROMETHEE

Robust Ordinal Regression (ROR) supports Multiple Criteria Decision Process by considering all sets of parameters of an assumed preference model, that are compatible with preference information elicited by a Decision Maker (DM). As a result of ROR, one gets necessary and possible preference relations in the set of alternatives, which hold for all compatible sets of parameters, or for at least one compatible set of parameters, respectively. In this paper, we propose an extension of ELECTRE and PROMETHEE methods to the case of the hierarchy of criteria, which was never considered before. Then, we adapt ROR to the hierarchical versions of ELECTRE and PROMETHEE methods.     

Social Support from Sponsorships as a Moderator of Acculturative Stress: Predictors of Effects on Refugees and Asylum Seekers

N = 63 refugees and asylum seekers, 27 women and 36 men with a mean age of 33.08 years (SD = 10.3) from Chechnya and Afghanistan were granted sponsorships for six months and were randomized to an intervention and a waiting-list control group. Only participants with a history of traumatization benefited from the intervention. For the traumatized sub-sample, sponsorships led to a significant and stable decrease in anxiety, depression, and psychological problems as compared to the control group, with effect sizes comparable to those of psychotherapy. The effects being rather palliative than instrumental, however, sponsorships did not instigate improvements in acculturation, societal contact, or coping capability. Women benefited more from the intervention than men, and Afghans more than Chechen.     

“Making work pay” in a rationed labor market

This paper empirically analyzes the labor supply effects of two “making work pay” reforms in Germany. We provide evidence in favor of policies that distinguish between low effort and low productivity by targeting individuals with low wages rather than those with low earnings. We discuss our results more generally and with comparisons to the family-based tax credits in force in the US and the UK. For the evaluation of the policies, we apply a static structural labor supply framework and explicitly account for demand-side constraints by using a double-hurdle model.     

Semiparametric predictive mean matching

Predictive mean matching is an imputation method that combines parametric and nonparametric techniques. It imputes missing values by means of the Nearest Neighbor Donor with distance based on the expected values of the missing variables conditional on the observed covariates, instead of computing the distance directly on the values of the covariates. In ordinary predictive mean matching the expected values are computed through a linear regression model. In this paper a generalization of the original predictive mean matching is studied. Here the expected values used for computing the distance are estimated through an approach based on Gaussian mixture models. This approach includes as a special case the original predictive mean matching but allows one to deal also with nonlinear relationships among the variables. In order to assess its performance, an empirical evaluation based on simulations is carried out.     

Deaf Children and Young People’s Experiences of Using Specialist Mental Health Services

Deaf children have an increased prevalence of mental health problems compared with hearing children. Generic Child And Adolescent Mental Health Services do not have the skills or expertise to meet the mental health needs of this group of children. Three teams in England provide specialist mental health services for deaf children. This research explored children’s experiences of using these services. Twenty‐four deaf children participated in the study. Overall children valued and benefited from the service. The expertise of the staff and the presence of deaf clinicians were key to these positive experiences.     

Democracy and Trade Union Action: A Comparative Overview

ABSTRACT: In this paper the author covers the current Italian debate on union representativeness and democracy, i.e. relations between union leadership and the rank-and-file, focusing on democratic procedures adopted (or not) in the internal decision-making process of the labour organisations. Experiments in the area of union self-regulation (autoregolamentazione) are discussed in connection with the collective bargaining process and strike action, mainly in public and private essential services. The author critically compares these experiments with more innovative solutions adopted in Spain, France, U.K., U.S.A. and Japan. Special attention is given to the role played by secret ballots in increasing union responsiveness.     

Does the General Strain Theory Explain Gambling and Substance Use?

General Strain Theory (GST: Agnew Criminology 30:47–87, 1992) posits that deviant behaviour results from adaptation to strain and the consequent negative emotions. Empirical research on GST has mainly focused on aggressive behaviours, while only few research studies have considered alternative manifestations of deviance, like substance use and gambling. The aim of the present study is to test the ability of GST to explain gambling behaviours and substance use. Also, the role of family in promoting the adoption of gambling and substance use as coping strategies was verified. Data from 266 families with in mean 8 observations for each group were collected. The multilevel nature of the data was verified before appropriate model construction. The clustered nature of gambling data was analysed by a two-level Hierarchical Linear Model while substance use was analysed by Multivariate Linear Model. Results confirmed the effect of strain on gambling and substance use while the positive effect of depressive emotions on these behaviours was not supported. Also, the impact of family on the individual tendency to engage in addictive behaviours was confirmed only for gambling.     

Building inclusive nations in the age of migration

Nation and diversity are often cast in oppositional terms. The present joint intervention explores the limits and possibilities of what we call ‘inclusive nation’, i.e. a nation which embraces rather than expunging diversity. To reflect on this idea, the Loughborough University Nationalism Network (LUNN) organized a symposium, bringing together both academics and relevant stakeholders, to explore both theoretically and practically the feasibility of the inclusive nation. For reason of space, here we present only the theoretical views of academics. While Billig and Yuval-Davis highlight the inherent exclusive thrust of nationalism, Kaufmann and Hearn suggest two distinct ways to move away the traditional understanding of nationalism as a site of singularity, oppression and exclusion. A final rejoinder by Nyhagen pushes the debate further interrogating the boundaries of national belonging.     

Build–operate–transfer (BOT): an emerging entry mode for service offshoring

Build–operate–transfer (BOT) is a well-established solution used in the engineering and construction industries for building different types of infrastructure (e.g. railways, highways, power plants). In recent years, BOT has increasingly been adopted by companies in the service industry as a mode for entering foreign markets. BOT in service offshoring (SO) is characterised by a number of significant peculiarities (e.g. different numbers of involved parties, fee methods, lengths of the concession period), which may call into question the possibility of extending existing findings that relate to infrastructure projects. The aims of this work are as follows: to collect and systematise existing knowledge on engineering and construction BOT projects; to highlight – through an exploratory case study – how these results could be applied to BOT in SO; and to shed light on the factors affecting the choice between different entry modes (including BOT).     

Sociosexuality,Commitment, Sexual Infidelity,and Perceptions of Infidelity: Data From the Second Love Web Site

This study explored the association between sociosexuality (behavior, attitudes, and desire) and commitment to understand sexual infidelity in current relationships. We also explored how these variables were associated with attitudes toward infidelity. Participants were romantically involved heterosexuals (N = 252; 51 women, 201 men; M_age = 41.13, SD = 9.82) registered on a dating Web site directed at romantically involved individuals. Results showed that sociosexuality, alongside commitment, was associated with sexual infidelity. Individuals who had (versus had not) previously engaged in infidelity reported more unrestricted sociosexuality, while reporting less commitment. For individuals reporting prior sexual infidelity, unrestricted sociosexual desire and lesser commitment were associated with more permissive perceptions of infidelity. For individuals reporting no prior sexual infidelity, greater commitment was always associated with more strict perceptions of infidelity. No gender differences emerged in the analyses. Also, no differences were found according to individual motivations (i.e., looking to know other people versus seeking casual sex) or relational motivations (i.e., individual registration versus registration as a couple) underlying individuals’ registration on the Web site. These results are an important addition to the literature on infidelity by analyzing a specific sample motivated to engage in infidelity. Implications for future research are discussed.
