The Decent Work Questionnaire: Development and validation in two samples of knowledge workers

This research develops a Decent Work Questionnaire (DWQ) to measure workers’ perceptions of decent work. Current measurements of decent work are almost completely lacking at the individual worker level of analysis, and this study contributes to filling the gap. The authors designed their DWQ based on the substantive elements used by the ILO in its Decent Work Agenda, with the final 31‐item version of the DWQ yielding seven factors related to decent work. Showing good reliability coefficient values and good convergent and discriminant validity, this DWQ could open up new avenues for empirical studies on the concept of decent work.     

Violent behaviour,victimization, self-esteem and physical activity of Spanish adolescents according to place of residence: a structural equation model / Conducta violenta,victimización,autoestima y actividad física de adolescentes españoles en función del lugar de residencia: un modelo de ecuaciones estructurales

This study aims to establish and verify an explanatory model for aggressive behaviour, self-esteem, victimization and physical activity in adolescents, and to use this explanatory model to analyse the association of place of residence with these variables. This research analysed 2,273 adolescents from the province of Granada (Spain) using the questionnaires Violent Behaviour at Schools, School Victimization Scale and Global Self-Esteem Scale. An analysis was carried out using structural equations. Results showed that relational and overt aggressiveness are related to self-esteem, victimization and physical activity. Furthermore, relational aggressiveness showed a stronger association with victimization and low self-esteem in adolescents who live in residential care. In addition, overt aggressiveness showed a stronger association with self-esteem in adolescents who live in family homes. Thus, exclusion and social rejection among peers have a greater impact on the victimization of young people who live outside of the family context.     

The role of intercultural,scientific and technological openness on innovation in European regions

This paper analyses the importance of openness for innovation in European regions. Openness is understood from a double angle: intercultural and scientific & technological. Our hypothesis is that each type of openness brings different kinds of knowledge into the regions and results on a different innovation output. S&T openness brings analytical forms of knowledge whilst intercultural openness brings tacit ones. Our results confirm this relationship as S&T openness shows a significant impact on patent activity, but not when a broader innovation indicator is used. Intercultural openness is highly significant when measuring innovation by a broader index and much less when measured by patents.     

Focused estimation for noisy and small data sets: a Bayesian minimum expected loss estimator approach

Central to many inferential situations is the estimation of rational functions of parameters. The mainstream in statistics and econometrics estimates these quantities based on the plug‐in approach without consideration of the main objective of the inferential situation. We propose the Bayesian Minimum Expected Loss (MELO) approach focusing explicitly on the function of interest, and calculating its frequentist variability. Asymptotic properties of the MELO estimator are similar to the plug‐in approach. Nevertheless, simulation exercises show that our proposal is better in situations characterised by small sample sizes and/or noisy data sets. In addition, we observe in the applications that our approach gives lower standard errors than frequently used alternatives when data sets are not very informative.     

Efficacy of Cyberbullying Prevention on Somatic Symptoms—Randomized Controlled Trial Applying a Reasoned Action Approach

The theory of reasoned action (ToRA) has been proposed as a framework for cyberbullying prevention design, targeting attitudes and norms. In this study effects of a long (10 weekly sessions) and a short (one day, four sessions) cyberbullying prevention program based on the ToRA were compared with a control group over 9 months. Longitudinal data from 722 students (mean age = 13.36) on cyberbullying, somatic symptoms, attitudes, and norms were analyzed within a structural equation model. Participation in the long intervention group significantly reduced cyberbullying (d = ?0.584) and somatic symptoms (d = ?0.316). No between‐group differences emerged for attitudes and norms. Developmental trajectories and associations were found to be as suggested by ToRA in both cross‐sectional and change‐score analyses.     

Big sister is watching you! Gender interaction and the unwritten rules of the Amsterdam red-light district

It is generally accepted that in sexual interaction men are the hunters and women the gatherers. An expressly sexual environment such as a red-light district would be expected to only reinforce this image. Strikingly enough, however, it is precisely prostitutes who seem able to break with these established gender roles. This ethnographic study uses participant observation to demonstrate how assumptions about sexual interaction may be specious: female prostitutes are frequently not the passive victims and male clients not the active sex-hunters they are taken for. Both the communicative function and protection of privacy play an important role in these processes in a red-light district. In the red-light district, gender interaction is bound by social regulation and unwritten rules that greatly exceed the influence of formal institutions. In this paper, the case of the red-light district "De Wallen" in Amsterdam, The Netherlands, is discussed in the context of several disciplines including urban anthropology, social psychology, geography, gender studies, and urban sociology.     

Commitment vs. Flexibility

We study the optimal trade‐off between commitment and flexibility in a consump‐ tion–savings model. Individuals expect to receive relevant information regarding tastes and thus they value the flexibility provided by larger choice sets. On the other hand, they also expect to suffer from temptation, with or without self‐control, and thus they value the commitment afforded by smaller choice sets. The optimal commitment problem we study is to find the best subset of the individual's budget set. This problem leads to a principal–agent formulation. We find that imposing a minimum level of savings is always a feature of the solution. Necessary and sufficient conditions are derived for minimum‐savings policies to completely characterize the solution. We also discuss other applications, such as the design of fiscal constitutions, the problem faced by a paternalist, and externalities.
