Lack of support for the association between facial shape and aggression: a reappraisal based on a worldwide population genetics perspective

Antisocial and criminal behaviors are multifactorial traits whose interpretation relies on multiple disciplines. Since these interpretations may have social, moral and legal implications, a constant review of the evidence is necessary before any scientific claim is considered as truth. A recent study proposed that men with wider faces relative to facial height (fWHR) are more likely to develop unethical behaviour mediated by a psychological sense of power. This research was based on reports suggesting that sexual dimorphism and selection would be responsible for a correlation between fWHR and aggression. Here we show that 4,960 individuals from 94 modern human populations belonging to a vast array of genetic and cultural contexts do not display significant amounts of fWHR sexual dimorphism. Further analyses using populations with associated ethnographical records as well as samples of male prisoners of the Mexico City Federal Penitentiary condemned by crimes of variable level of inter-personal aggression (homicide, robbery, and minor faults) did not show significant evidence, suggesting that populations/individuals with higher levels of bellicosity, aggressive behaviour, or power-mediated behaviour display greater fWHR. Finally, a regression analysis of fWHR on individual"s fitness showed no significant correlation between this facial trait and reproductive success. Overall, our results suggest that facial attributes are poor predictors of aggressive behaviour, or at least, that sexual selection was weak enough to leave a signal on patterns of between- and within-sex and population facial variation.

Observer reactions to workplace mistreatment

This study explored observer reactions to workplace interpersonal mistreatment using an inductive analysis approach. I conducted 32 interviews with a wide sample of working professionals from various backgrounds and industries to examine how observers react to the unfolding process of workplace interpersonal mistreatment incidents. Specifically, the goal of this study was to gain a deeper and closer understanding of observer reaction processes by examining first-hand accounts of employees who have witnessed co-workers being mistreated by others. I generated typologies of reported observer affective, cognitive, and behavioral reactions that emerged from their stories, and I identified what employees believe are important factors that inhibit or enable intervention. Results reveal that a majority of employees are not inclined to intervene during an ongoing mistreatment incident, and that observers who intervened during the incident reported different appraisal processes than observers who only intervened afterwards, or who did not intervene at all. From these personal accounts of observing workplace mistreatment, I interpreted that observers generally react to interpersonal mistreatment incidents in two phases, and that how targets reacted after an incident was an important trigger that propelled observers to become involved afterwards, even if they did not have the desire or the intention to do so. These findings have implications for current theories on observer intervention to mistreatment in the workplace.

Multimodal counter-argumentation in the workplace : the contribution of gesture and gaze to the expression of disagreement

This paper examines argumentative talk-in-interaction in the workplace. It focuses on counter-argumentative references, which consist of the various resources that the opponent uses to refer to the origin/source of his/her opposition, namely the confronted position and the person who expressed it. Particular attention is paid to the relationship - in terms of sequential positioning and referential extension - between reported speech, polyphony, pointing gestures and shifts in gaze direction. Data are taken from workplace management meetings that have been recorded in New Zealand by the Language in the Workplace Project.

Entraînement à faire face au stress professionnel pour les personnes avec un retard intellectuel : une étude pilote / Training to cope with workplace stress for people with mild intellectual disability: a pilot study

Cette étude pilote cherche à tester la faisabilité de l'entraînement à la cohérence cardiaque avec des personnes atteintes d'un retard intellectuel dans le cadre d'un atelier protégé. Un entraînement à la cohérence cardiaque est proposé aux participants volontaires pour une durée de deux semaines à la prise de travail, matin et après-midi. Une appréciation des effets de ces exercices respiratoires est effectuée avant et après entraînement par la mesure d'indices de variabilité cardiaque et une évaluation de la perception du stress professionnel. La comparaison des valeurs récoltées pré et post-entraînement révèle une amélioration significative dans l'activation de la branche parasympathique. L'évaluation des valeurs du RMSSD sont inversement corrélées à l'évaluation des participants de leurs stress perçu. Ensemble, nos résultats indiquent que la population atteinte de retard intellectuel est réceptive à l'apprentissage de la cohérence cardiaque et que la baisse de leur stress est liée à une hausse de l'activité inhibitrice parasympathique, plutôt qu'à une diminution de l'activité excitatrice sympathique. Les considérations offertes par cette étude exploratoire doivent être étayées, mais permettent d'ores et déjà d'ouvrir de nouvelles perspectives dans la prise en charge de populations pour lesquelles la gestion du stress est mal adaptée.

Sex ratio bias, male aggression, and population collapse in lizards.

The adult sex ratio (ASR) is a key parameter of the demography of human and other animal populations, yet the causes of variation in ASR, how individuals respond to this variation, and how their response feeds back into population dynamics remain poorly understood. A prevalent hypothesis is that ASR is regulated by intrasexual competition, which would cause more mortality or emigration in the sex of increasing frequency. Our experimental manipulation of populations of the common lizard (Lacerta vivipara) shows the opposite effect. Male mortality and emigration are not higher under male-biased ASR. Rather, an excess of adult males begets aggression toward adult females, whose survival and fecundity drop, along with their emigration rate. The ensuing prediction that adult male skew should be amplified and total population size should decline is supported by long-term data. Numerical projections show that this amplifying effect causes a major risk of population extinction. In general, such an "evolutionary trap" toward extinction threatens populations in which there is a substantial mating cost for females, and environmental changes or management practices skew the ASR toward males.

The republican case for workplace democracy

The republican case for workplace democracy (WD) is presented and defended from two alternative means of ensuring freedom from arbitrary interference in the firmnamely, (a) the right to freely exit the firm and (b) workplace regulation. This paper shows, respectively, that costless exit is neither possible nor desirable in either perfect or imperfect labor markets, and that managerial discretion is both desirable and inevitable due to the incompleteness of employment contracts and labor legislation. The paper then shows that WD is necessary, from a republican standpoint, if workers" interests are to be adequately tracked in the exercise of managerial authority. Three important objections are finally addressed (i) that WD is redundant, (ii) that it is unnecessary provided that litigation and unionism can produce similar outcomes, and (iii) that it falls short of ensuring republican freedom compared to self-employment.

Dynamic patterns of flow in the workplace: characterizing within-individual variability using a complexity science approach

As a result of the growing interest in studying employee well-being as a complex process that portrays high levels of within-individual variability and evolves over time, this present study considers the experience of flow in the workplace from a nonlinear dynamical systems approach. Our goal is to offer new ways to move the study of employee well-being beyond linear approaches. With nonlinear dynamical systems theory as the backdrop, we conducted a longitudinal study using the experience sampling method and qualitative semi-structured interviews for data collection; 6981 registers of data were collected from a sample of 60 employees. The obtained time series were analyzed using various techniques derived from the nonlinear dynamical systems theory (i.e., recurrence analysis and surrogate data) and multiple correspondence analyses. The results revealed the following: 1) flow in the workplace presents a high degree of within-individual variability; this variability is characterized as chaotic for most of the cases (75%); 2) high levels of flow are associated with chaos; and 3) different dimensions of the flow experience (e.g., merging of action and awareness) as well as individual (e.g., age) and job characteristics (e.g., job tenure) are associated with the emergence of different dynamic patterns (chaotic, linear and random).

Workplace Social Capital and Employee Health

Työyhteisön sosiaalinen pääoma ja työntekijöiden terveys Monien tutkimusten mukaan sosiaalinen pääoma vaikuttaa terveyteen. Vaikka työssä käyvä väestönosa on merkittävän osan valveillaoloajastaan työyhteisössä, siellä kertyvää sosiaalista pääomaa on toistaiseksi tutkittu vähän. Tässä tutkimuksessa selvitettiin työyhteisön sosiaalisen pääoman ja kuntatyöntekijöiden terveyden välistä yhteyttä pitkittäisasetelmassa hyödyntäen Kuntasektorin henkilöstön seurantatutkimuksen aineistoa vuosilta 2000–2005. Yhteensä 48592 kuntatyöntekijää vastasi kyselyyn vuosina 2000–02 (vastausprosentti 68 %). Heistä 35914 (77 %) osallistui myös seurantatutkimukseen vuosina 2004–05. Tutkimuksessa kehitettiin kyselyyn perustuva työyhteisön sosiaalisen pääoman mittausmenetelmä. Työntekijän omaan arvioon perustuvan sosiaalisen pääoman lisäksi mitattiin työyhteisön sosiaalista pääomaa käyttämällä samassa työyhteisössä työskentelevien muiden työntekijöiden keskimääräistä arviota sosiaalisesta pääomasta. Terveyttä mitattiin kysymyksellä koetusta terveydestä. Masennusta arvioitiin sekä kysymällä lääkärin toteamasta masennuksesta että masennuslääkeostoilla Kelan lääkerekistereistä. Analyyseihin otettiin mukaan vain ne kuntatyöntekijät, jotka olivat lähtötilanteissa terveitä eli kokivat terveytensä hyväksi tai heillä ei ollut aiempaa diagnosoitua tai lääkehoitoa vaatinutta masennusta. Tulosten analysointiin käytettiin monitasomallinnusta. Tulokset vakioitiin sosiodemografisten tekijöiden ja terveyskäyttäytymisen suhteen. Neljän vuoden seurannassa sekä jatkuvasti vähäinen että vähenevä yksilön sosiaalinen pääoma työssä lisäsi riskiä koetun terveyden heikkenemiseen niillä kuntatyöntekijöillä, jotka eivät vaihtaneet työpaikkaa seurannan aikana ja jotka seurannan alussa kokivat terveytensä hyväksi. Tulos ei selittynyt sosiodemografisilla tekijöillä tai terveyskäyttäytymisen eroilla. Tuloksen merkittävyyttä tuki havainto, että myös työtoverien arvioon perustuva sosiaalinen pääoma ennusti oman terveyden huononemista seuranta-aikana. Niillä työntekijöillä, jotka työskentelivät sellaisissa työyhteisöissä, joissa koko seurannan ajan oli vähiten sosiaalista pääomaa, oli lähes 1.3 -kertainen riski terveyden heikentymiseen. Vähäinen omaan arvioon perustuva sosiaalinen pääoma työssä ennusti myös masennuksen ilmaantuvuutta lähtötilanteessa ei-masentuneilla lähes neljän vuoden seurannassa. Matalaan sosiaaliseen pääomaan liittyi 20–50 % suurempi todennäköisyys sairastua masennukseen seurannan aikana niin itseraportoidun lääkärin totea-man masennuksen kuin masennuslääkeostojen perusteella. Tätä tulosta ei kuitenkaan pystytty toistamaan käyttämällä oman arvion sijasta työtoverien arviota työyhteisön sosiaalisesta pääomasta. Tutkimusta sosiaalisen pääoman vaikutusta masennuksen ilmaantumiseen jatkettiin selvittämällä miten sosiaalisen pääoman eri ulottuvuudet vaikuttivat masennuksen ilmaantumiseen. Tulosten mukaan sosiaalisen pääoman vertikaalinen komponentti (työntekijöiden ja esimiesten välinen luottamus, vastavuoroisuus ja jaetut arvot ja normit, jotka edesauttavat yhteistyötä) sekä horisontaalinen komponentti (työntekijöiden välisissä suhteissa yhteistyöstä, luottamuksesta ja vastavuoroisuudesta syntyvä sosiaalinen pääoma) vaikuttivat itsenäisesti masennusriskiin. Tutkimuksen perusteella korkea työyhteisön sosiaalinen pääoma saattaa vaikuttaa edullisesti työntekijöiden terveyteen. Jos näin on, olisi tärkeää edistää työyhteisöjen sosiaalista pääomaa ja kannustaa sellaiseen toimintaan, joka lisää suvaitsevaisuutta, luottamusta ja vastavuoroisuutta sekä työntekijöiden kesken että työntekijöiden ja esimiesten välillä.

Aggression and its Management in Adolescent Forensic Psychiatric Care

The overall goal of this study was to explore and identify good aggression management methods and on that basis to produce recommendations for aggression management in the adolescent forensic setting. The study was conducted in three phases. In Phase I, staff’s (n = 58) perception of adolescent aggressive behaviour and methods to manage it was examined. In Phase II, staff’s (n = 30) perception of treatment settings and treatment interventions available were studied. In Phase III, the effectiveness of an aggression management programme was evaluated. The data were collected during the period 2004-2007. Participants perceived adolescent aggressive behaviour in a similar way and described aggressive behaviour as being a comprehensible phenomenon. Management methods used to control aggressive situations were alike, although the practical solutions varied between the study units, especially regarding coercive methods. Staff members proposed more time and better opportunities to discuss and evaluate the aggression situation in order to improve the methods used. The treatment settings were similar in studied forensic units and interventions were primarily focused on psychological aspects, including management of aggressive behavior. A comprehensive aggression management programme proved to be effective in decreasing incidents of violence. The use of coercive methods in aggression situations decreased and injuries to the staff became less frequent. If staff members intend to apply high quality management methods in aggression situations they have to share a consistent understanding of aggressive behaviour and need to be aware of the various methods available. In addition, they should learn more about assessment methods in order to improve aggression management. International comparison of aggression, methods for managing it and service provision creates a starting point for developing equal care provision and realization within and between European countries.

The adjustment from Russia to Finland for corporate repatriates: How the repatriation experience influences readjustment in the workplace

To manage foreign operations, companies must often send their employees on international assignments. Repatriating these expatriates can be difficult because they have been forgotten during their posting, and their new experiences are not utilised. In addition to the possible difficulties in organisational repatriation, the returnee can suffer from readjustment problems after a lengthy stay abroad has changed their habits and even identity. This thesis examines the repatriation experience of Finnish assignees returning from Russia. The purpose of the study is to understand how the repatriation experience influences their readjustment to work in Finland. This experience is influenced by many factors including personal and situational changes, the repatriation process, job and organisational factors, and individual’s motives. The theoretical background of the study is founded on two models of repatriation adjustment. A refined, holistic theoretical framework for the study is created. It describes the formation of the repatriation experience and its importance for readjustment to work and retention. The qualitative research approach is suitable for the thesis which examines the returnees’ personal experiences and feelings: a qualitative case study aims to explain the phenomenon in-depth and comprehensively. The data was collected in summer 2013 through semi-standardised interviews with eight Finnish repatriates. They had returned from Russia within the last two years. The data was analysed by structuring the interview transcripts using template analysis. The results supported earlier literature and suggest that the re-entry remains a challenging phase for both the individual and the company. For some, adjusting to a new job was difficult for various reasons. The repatriates underwent personal change and development and felt it was for the better. Many repatriates criticised the company’s repatriation process upon return. Finding a suitable return job was not clear. Instead, the returnees had to be active in finding a new position. Many assignees had only modest career-related motives regarding the assignment and they had realistic expectations about the return. Therefore they were not extremely surprised or dissatisfied when they were not actively offered positions or support by the company. The significance of motives stood out even more than the theory predicted. As predicted, they are linked to the expectations of employees. Moreover, if the employees are motivated to remain in the company, they can tolerate partly a negative repatriation experience. Despite the complexity of the return and readjustment, the assignment as a whole was seen as a rewarding experience by all participants.

Reduction of intraspecific aggression in adult rats by neonatal treatment with a selective serotonin reuptake inhibitor

Most studies suggest that serotonin exerts an inhibitory control on the aggression process. According to experimental evidence, this amine also influences growth and development of the nervous tissue including serotoninergic neurons. Thus, the possibility exists that increased serotonin availability in young animals facilitates a long-lasting effect on aggressive responses. The present study aimed to investigate the aggressive behavior of adult rats (90-120 days) treated from the 1st to the 19th postnatal day with citalopram (CIT), a selective serotonin reuptake inhibitor (20 mg/kg, sc, every 3 days). Aggressive behavior was induced by placing a pair of rats (matched by weight) in a box (20 x 20 x 20 cm), and submitting them to a 20-min session of electric footshocks (five 1.6-mA - 2-s current pulses, separated by a 4-min intershock interval). When compared to the control group (rats treated for the same period with equivalent volumes of saline solution), the CIT group presented a 41.4% reduction in the duration of aggressive response. The results indicate that the repeated administration of CIT early in life reduces the aggressive behavior in adulthood and suggest that the increased brain serotoninergic activity could play a role in this effect.
