The influence of different dimensions of social comparison on performance measure choice and team composition

Empirical research in the economic literature is increasingly addressing the implications of social comparison on incentive contracts by using analytical principal-agent models. Contrary to the existing investigations, which are primarily based on the assumption that individuals exclusively compare monetary income, theories of behavioral science suggest that monetary income and effort represent different dimensions of social comparison, which are weighted individually. Using a LEN framework, the present study focuses on this aspect of social comparisons and discusses how these dimensions and their individual weights affect optimal contract design and contract efficiency. I consider status-seeking agents who compare themselves to each other and differ with regard to their intensity of social preferences and the specific relevance of dimensions. Finally, I draw conclusions for the drafting of contracts with respect to (1) the choice of performance measures and (2) an optimal team composition.     

Subclinical Psychopathic Traits and Romantic Attachment in Treatment-Seeking Couples

Subclinical psychopathic personality traits have been associated with multiple indicators of couple distress and romantic attachment insecurities but essentially in community samples. This study examined dyadic associations between primary and secondary psychopathy and attachment anxiety and avoidance, assessed with self-reported measures, in 183 French-Canadian cohabiting partners seeking couple therapy. Two Actor-Partner Interdependence Models were tested: Model 1 considered psychopathic traits as independent variables and Model 2 treated attachment insecurities as independent variables. Analyses revealed that in both partners, secondary psychopathy was associated with attachment anxiety and avoidance (Models 1 and 2), while primary psychopathy was not only associated with attachment anxiety (Model 2; actor associations). Partner effects between primary and secondary psychopathy in men and women's attachment anxiety were also found in both models. These findings complement those reported in community samples and have clinical implications for treatment-seeking couples.

Quite an encumbrance? Work-related obstacles to Finnish fathers’ take-up of parental leave

ABSTRACT

An ideal of involved fatherhood has become popular in the developed countries, but even countries like Finland that have introduced an individual father’s quota to parental leave are far from gender equality in parents’ leave practices. Lack of support and negative attitudes at workplaces or pressure at work are among the obstacles to fathers’ leave take-up. The study used survey data from fathers and interviews at workplaces to explore the role of work and workplaces among the many aspects related to fathers’ possibilities of taking leave. The results showed that fathers’ income and workplace characteristics were associated with taking leave. Few fathers mentioned employers’ objection as a hinder. Father’s recent unemployment and anticipated difficulty of taking a long time off played a more important role. At workplaces, the obstacles to taking long leave were related to fathers’ ideals about a committed worker and to the nature and organizing of work. Additionally, the leave exceeding fathers’ quota might not be understood as ‘for fathers’. The spouse’s situation and fathers’ gendered perceptions about parental responsibilities were also important for leave practices. The findings suggest that policy development towards a longer father’s quota could make fathers’ care responsibilities visible also at workplaces.     

Antecedents and effects of individual ambidexterity – A cross-level investigation of exploration and exploitation activities at the employee level

For long-term success, companies need to adapt to technological and environmental change. Organizational ambidexterity, which balances the exploration of new opportunities with the exploitation of existing capabilities, is increasingly viewed as a promising approach to tackle this challenge. However, despite the important role of individuals for firms' ambidexterity and performance, evidence on how exploration of new opportunities and exploitation of existing capabilities are triggered at an individual level and on their subsequent effects on overall performance is still lacking. Accordingly, the present research shifts the focus from organizational ambidexterity to individual ambidexterity. Based on data from 415 employees, the results of structural equation modeling show that both organizational architecture and organizational context can be used to induce individual ambidexterity. Furthermore, positive performance effects of individual ambidexterity across different organizational levels, namely the team and department levels, are confirmed.     

City dwelling wild bees: how communal gardens promote species richness

Urban areas consist of wide expanses of impervious surfaces which are known to negatively affect insect biodiversity in general, but green spaces within cities have the potential to provide necessary habitat and foraging resources. Although, communal gardens were primarily intended to provide fresh, regional food to denizens, these green islands also host a surprisingly high number of wild bee species.

The gardens were characterized based on structural elements such as flower frequency, the relative percentage of lawn, trees, shrubs, planted crops and infrastructure (e.g. seating possibilities or garden houses). Further, the effects of different landscape structures surrounding the gardens and distance to the city center were analyzed on the total wild bee species richness and functional traits. Focusing on these putative influencing factors, statistical analyses calculating random decision forests along with generalized linear mixed models were applied. With 113 observed wild bee species, communal gardens provide habitat for a quarter of all known species in Vienna. In conclusion, results revealed that only elements within the gardens had an effect on species richness, with flower frequency as the major positive driver. The examined communal gardens promote and conserve wild bees independent from the location within the city or garden size. Furthermore, these green patches are important sanctuaries, hosting rare and threatened species as well as remarkably special wild bee communities.

     

Skewed zero-bound distributions and process capability indices for upper specifications

A common practical situation in process capability analysis, which is not well developed theoretically, is when the quality characteristic of interest has a skewed distribution with a long tail towards relatively large values and an upper specification limit only exists. In such situations, it is not uncommon that the smallest possible value of the characteristic is 0 and this is also the best value to obtain. Hence a target value 0 is assumed to exist. We investigate a new class of process capability indices for this situation. Two estimators of the proposed index are studied and the asymptotic distributions of these estimators are derived. Furthermore, we suggest a decision procedure useful when drawing conclusions about the capability at a given significance level, based on the estimated indices and their asymptotic distributions. A simulation study is also performed, assuming that the quality characteristic is Weibull-distributed, to investigate the true significance level when the sample size is finite.     

Reliable Professionals,Sensitive Dads and Tough Fighters

The significance and complexity of mostly male-dominated military peacekeeping forces continues to grow globally, as does the complexity of the masculinities performed in them. This article discusses the discourses and performances of peacekeeper masculinities, drawing on a qualitative case study of Finnish peacekeeping forces. The self-image of Finland as a provider of ideal peacekeepers and practising progressive gender policy is critically analysed. Taking the notion of multiple masculinities as a starting point, three indicative categories of Finnish peacekeeper masculinities are examined. Discourses of ‘amateur professionals’ and ‘peacekeeper fathers’ create space for military peacekeepers to show aspects of masculinity not associated with traditional military masculinities. The third discourse of ‘tough fighters’, however, harks back to more traditional ‘warrior’ concepts. Official gender mainstreaming efforts and assumptions that these attitudes are internalized ‘naturally’ by Finns are put into question by deprecatory or ambiguous attitudes towards gender equity and sexual exploitation. Despite being part of multi-national forces, peacekeeper masculinities are defined based on presumed notions of ‘national character’.
