Grit or Honesty-Humility? New Insights into the Moderating Role of Personality between the Health Impairment Process and Counterproductive Work Behavior

It is acknowledged that chronic job demands may be depleting workers’ stamina resulting in burnout conditions and ultimately causing further health problems. This relation, known as health impairment process, has recently been considered as a possible explanation for the emergence of counterproductive work behavior (CWB). The present work aims to examine the role of two personality traits (i.e., Grit and Honesty-Humility) in this process. The results, based on a sample of 208 private service sector employees, confirm the presence of a fully mediated process and show how Honesty-Humility positively moderates the relationship between job demands and exhaustion, whereas Grit has a negative effect on the relation between exhaustion and CWB. Implications for assessment procedure and hiring decisions are discussed.

Serotonin transporter gene polymorphisms and treatment-resistant depression.

Major Depression Disorder (MDD) is a serious mental illness that is one of the most disabling diseases worldwide. In addition, approximately 15% of depression patients are defined treatment-resistant (TRD). Preclinical and genetic studies show that serotonin modulation dysfunction exists in patients with TRD. Some polymorphisms in the promoter region of the serotonin transporter gene (SLC6A4) are likely to be involved in the pathogenesis/treatment of MDD; however, no data are available concerning TRD. Therefore, in order to investigate the possible influence of SLC6A4 polymorphisms on the risk of TRD, we genotyped 310 DSM-IV MDD treatment-resistant patients and 284 healthy volunteers. We analysed the most studied polymorphism 5-HTTLPR (L/S) and a single nucleotide substitution, rs25531 (A/G), in relation to different functional haplotype combinations. However the correct mapping of rs25531 is still debated whether it is within or outside the insertion. Our sequencing analysis showed that rs25531 is immediately outside of the 5-HTTLPR segment. Differences in 5-HTTLPR allele (p=0.04) and in L allele carriers (p<0.05) were observed between the two groups. Concerning the estimated haplotype analyses, L(A)L(A) homozygote haplotype was more represented among the control subjects (p=0.01, OR=0.64 95%CI: 0.45-0.91). In conclusion, this study reports a protective effect of the L(A)L(A) haplotype on TRD, supporting the hypothesis that lower serotonin transporter transcription alleles are correlated to a common resistant depression mechanism.

Role of allelic variants of FK506-binding protein 51 (FKBP5) gene in the development of anxiety disorders.

Anxiety disorders exhibit remarkably high rates of comorbidity with major depressive disorder (MDD). Mood and anxiety disorders are considered stress‐related diseases. Genetic variations in the co‐chaperone FK506‐binding protein 51, FKBP5, which modulates the function of glucocorticoid receptors, have been associated with an increased risk for the development of posttraumatic stress disorder, but data regarding its role in MDD are controversial. The aims of this study were to clarify the role of the FKBP5 gene in depression and anxiety disorders through a case–control study and an association study with personality traits using the Temperament and Character Inventory (TCI) in healthy subjects.

Studying teamwork and team climate by using a business simulation: How communication and innovation can improve group learning and decision-making performance

Purpose – The purpose of this paper is to investigate how dimensions related to teamwork and team climate can influence decision making and learning of teams (performance). In order to understand which factors are more effective, several relevant group and team characteristics drawn from classical literature on groups and more recent empirical team simulation research have been considered. Design/methodology/approach – The paper presents the results of a longitudinal study carried out during four months. A total of 183 Italian participants, divided into 50 teams of three (n=24), four (n=19) and five (n=7) members, have been involved in a business game developed by several European savings banks and simulating a real stock market environment. The aim of each team is not only to earn virtual money, but also learning long-term strategies to develop profitable investments without losing sight of economic factors. Findings – Based on literature review, the authors tested three group levels (intragroup relations level, self-member level and group-design level) by making three hypotheses concerning the teams involved in the simulation and investigated the communication and innovation (CI) dimension from the Italian version of the team climate inventory (TCI) by Ragazzoni et al. A correlation between team performance and CI was found (r=0.301 p=0.048), which is in line with the hypothesis that such factors as communication and support for innovation can affect the decision-making performance. Originality/value – The results presented in the paper let practitioners understand which dynamics characterize teamwork activities and how such aspects as communication and support for innovation can lead to group learning and decision-making performance. The simulation used in this research is an empirical way to study team performance and group learning without other noise variables.

The career decision-making competence: a new construct for the career realm

Purpose This paper aims to link findings from laboratory-based decision-making research and decision-making competence (DMC) aspects that may be central for career-related decision-making processes. Past research has identified individual differences in rational responses in decision situations, which the authors refer to as DMC. Although there is a robust literature on departures from rational responses focused on heuristics and biases (H&B) in decision-making, such evidence is largely confined to group-level differences observed in psychology laboratories and has not been extended to the realm of career development and workforce behavior. Design/methodology/approach By first introducing the concept of DMC and contextualizing it within organizations and the work environment, the paper outlines a review on recent development concerning debiasing interventions in organizations and provides insights on how these may be effective with regard to organizational performance and individual career development. Findings The contribution presents a perspective to improve knowledge about career decision-making competence (C-DMC) by presenting an approach linking decision-making research to interventions aiming at managing H&B and systematic misperceptions in career processes. Originality/value This contribution is one of the few linking decision-making research to the applied context of organizations and of career competences. Moreover, while some research has treated decision-making skills as traits, this contribution provides support to consider them developable as competencies.

The impact of occupational rewards on risk taking among managers

Managers often have to deal with the financial and ethical risks that companies face. Evidence from risk management research suggests a negative relationship between people’s age and risk taking tendencies. Within such a framework, the present contribution examines how different perceived occupational rewards may mediate or interact with the relationship between age and risk taking of managers at the company level. Our results show that perceived rewards in terms of job security partially mediate the relationship between age and ethical risk taking, while perceived rewards related to job promotion moderate the effect of age on financial risk taking. We further discuss the role of different organizational strategies to preserve an organization’s health.

Seizure Adequacy Markers and the Prediction of Electroconvulsive Therapy Response

Objectives Electroconvulsive therapy (ECT) is the most effective therapy for patients with treatment-resistant depression; however, some patients do not respond or relapse in a short time. Electroconvulsive therapy stimulus parameters may be related to the outcome. We carried out a retrospective study review to investigate various ECT parameters in relation to the outcome, clinical variables, and pharmacological treatments. Our aim was to understand which factors could be considered putative seizure quality markers and which are relevant to clinical practice. Methods Two physicians evaluated the seizure length, the postictal suppression index, the wave amplitude, tachycardia, and hemispheric brain wave synchronicity in a double-blind manner for 45 treatment-resistant depression patients receiving ECT. Results The analysis showed a significant association between the outcome and the ECT seizure quality measured by the parameters (P = 9.9 × 10−5). Among patients with poor-quality seizures, 61.5% relapsed after approximately 1 month from the last ECT session. Particularly, there was an association between higher symptomatology decrease and higher quality of hemispheric brain wave synchronicity (P = 5.0 × 10−6), as well as a higher wave amplitude (P = 0.01). Conclusions Our results confirm that ECT seizure quality was strongly correlated with the decrease of depressive symptomatology.

The role of the potassium channel gene KCNK2 in major depressive disorder

Six single nucleotide polymorphisms (SNPs) of the KCNK2 gene were investigated for their association with major depressive disorder (MDD) and treatment efficacy in 590 MDD patients and 441 controls. The A homozygotes of rs10779646 were significantly more frequent in patients than controls whereas G allele of rs7549184 was associated with the presence of psychotic symptoms and the severity of disease. Evaluating the Sequenced Treatment Alternatives to Relieve Depression (STAR*D) dataset, we confirmed our findings.

Competence-based analysis of needs in VET teachers and trainers: an Italian experience

Purpose – The aim of the research presented here was to detect, in line with the European Union’s “Education and Training 2020” work program, the training needs of teachers and trainers working in the vocational education and training (VET) system in the Italian Region of Veneto to design courses, experiences and other training programs tailored to meet the needs emerged. Design/methodology/approach – Four focus groups were including VET teachers and trainers were created, two before the construction and two after the online administration of an ad hoc questionnaire asking teachers and trainers to rate 67 competencies (43 for teachers, 24 for trainers) on the two dimensions of self-assessment (explicitly defined as the current level of mastery) and importance (explicitly defined as the expected level of mastery). Eight hundred twelve teachers and 166 trainers filled in the questionnaire which also asked them to give suggestions about the courses, experiences and other training programs to be designed. Fin...

Designing a Homo Psychologicus More Psychologicus: Empirical Results on Value Perception in Support to a New Theoretical Organizational-Economic Agent Based Model

The study presents a new approach of modelling human behavior based on empirical evidence on individual differences in cognitive science and behavioral economics fields. Compared to classical studies of economics, empirical research makes use of the descriptive approach to analyze human behavior and to create models able to explain the behavior of investors and organizational traders in a more realistic way. Consistently, an economic assumption that has been strongly disputed by scientists is the concept of Homo Economicus, which is currently considered unable to capture all the details and variability that characterize human behavior (which we define, in opposition to the economic label, Homo Psychologicus). Thanks to recent empirical studies and the development of such advanced techniques as agent based models, new simulation studies are now capable of investigating a higher number of psychological variables. However, models which implement heuristics or fallacies often distribute these characteristics among all agents without distinction. The present study shows how it is possible to design multiple agents considering individual differences, which can have a different impact on organizational and economic behavior. Starting from several empirical studies, which show a negative relation between optimism and loss aversion, coefficients of the Value function of the Prospect theory have been reviewed to create agents characterized by different psychological strategies used to manage costs and risks.
