Exercise commitment and proneness to eating disorders in a group of physical education teachers

The study examined the association of exercise commitment with proneness to eating disorders in 50 physical education teachers who had been practicing various aerobic sports at least three times a week for at least 5 years. Significant coefficients were found between Commitment to Exercise Scale scores, the number of weekly training sessions, and scores on the Eating Disorders Inventory-2 scales measuring Maturity Fears, Social Insecurity, Perfectionism, and Asceticism. However, no relationship was found between the Commitment to Exercise Scale and the Eating Disorders Inventory-2 variables measuring anorexic tendencies (such as Drive for Thinness, Body Dissatisfaction, and Bulimia). Findings suggest the presence of some psychological factors common to both anorexic tendencies and excessive exercising but not complete overlap, so a rather more complex pattern of relationships appears to be mediated by sex and personality characteristics.     

Homeless Adults’ Recovery Experiences in Housing First and Traditional Services Programs in Seven European Countries

Across Europe, as governments turn to housing-led strategies in attempts to reverse rising rates of homelessness, increasing numbers of Housing First (HF) programs are being implemented. As HF programs become more widespread, it is important to understand how service users experience them compared to the more prevalent traditional treatment-first approach to addressing long-term homelessness. Although there is a large body of research on service users’ experiences of Housing First compared to treatment-first in North American contexts, comparatively less is known about how these two categories of homeless services are experienced in the European context. In a correlational and cross-sectional study, part of a larger examination of homelessness in Europe, participants (n = 520) engaged with either HF (n = 245) or traditional services (TS; n = 275) programs in seven countries completed measures of their experiences of services (consumer choice, housing quality, and service satisfaction) and recovery (time in independent housing, psychiatric symptoms, and community integration). Across the seven countries, participants engaged with HF programs reported experiencing more consumer choice, better perceived housing quality, and more satisfaction with services than participants engaged in TS programs. Participants in HF programs also reported a greater proportion of time in independent accommodation, fewer psychiatric symptoms, and more community integration. Varying patterns of association between experiences of services and recovery outcomes were observed. Findings indicate HF consistently predicts greater recovery than TS across diverse sociopolitical and economic contexts. Implications of findings for configurations of homeless services and homeless services policy are discussed.

Rhetorical Argumentation in Italian Academic Discourse

The recent trend in institutional communication research seems to foster the image of the University as a private organization significantly oriented towards a policy of customer satisfaction. Following the concept of organizational culture, institutional settings too are conceived as organizational contexts, where discourse is a privileged vehicle to convey and spread values, traditions and artifacts, both through internal and external communication practices. Thus, within academic discourse organizational culture is shaped and perpetuated by specific devices of rhetorical argumentation. The corpus of data consists of two different examples of academic discourse: the self promotional endorsement letters of the academic candidates to the chancellor’s position on occasion of the elections and the inaugural speeches proclaimed by the chancellors in charge during the opening celebration of the academic year. The first kind of academic discourse could be meant as an example of political discourse since the candidates use communication strategically and manipulate their academic membership as a rhetorical device to support their aims. On the other hand, the second example is a mere celebration of academic culture which through linguistic rituals recalls and perpetuates the basic values of this microcosm. The data have been analysed with the critical discourse analysis and diatextual analysis which pay particular attention to the context of speech. Moreover, attention has been focused on the metaphors and on the meta-discursive cues. The results show that although with different purposes academic discourse use similar discursive and rhetorical strategies as both belong to the same organization.     

‘Eppur si move’: The Association Between Electrophysiological and Psychophysical Signatures of Perceived Movement Illusions

Vibration applied to muscle tendons induces an illusory perception of movement by activating spindle receptors and Ia afferent fibers. While neural structures supporting such illusions are quite defined, functional and psychophysical correlates of their perception have not been deeply investigated. The authors aimed at exploring subjective perception of illusory movements thanks to a repeated-stimulation multimodal approach. The integrated analysis of electroencephalography, source data (standardized low-resolution brain electromagnetic tomography–sLORETA), and psychophysical evaluation pointed at the activation of a frontoparietal sensorimotor network, with prefrontal-medial regions mainly involved in supporting the awareness for illusory movements. Further, illusions showed consistency in terms of presence, vividness, and duration. Finally, superior parietal structures seemed to play an important role in self-attribution of agency and ownership during such experiences.     

Shrinkage estimation of the three-parameter logistic model

The three-parameter logistic model is widely used to model the responses to a proficiency test when the examinees can guess the correct response, as is the case for multiple-choice items. However, the weak identifiability of the parameters of the model results in large variability of the estimates and in convergence difficulties in the numerical maximization of the likelihood function. To overcome these issues, in this paper we explore various shrinkage estimation methods, following two main approaches. First, a ridge-type penalty on the guessing parameters is introduced in the likelihood function. The tuning parameter is then selected through various approaches: cross-validation, information criteria or using an empirical Bayes method. The second approach explored is based on the methodology developed to reduce the bias of the maximum likelihood estimator through an adjusted score equation. The performance of the methods is investigated through simulation studies and a real data example.     

Past and future of near-infrared spectroscopy in studies of emotion and social neuroscience

Near-infrared spectroscopy (NIRS) enables the non-invasive measurement of spatiotemporal characteristics of brain function, which has received increasing attention during the last years. This new birth of interest is attributable to unique characteristics of the NIRS technique, which may be summarised in certain technical advantages: its experimental and ecological validity and the extension of application to clinical samples. This paper presents the main applications of the NIRS technique that measures changes in brain activation to study emotions and social neuroscience field. In the first part of this paper, we discuss the basic principles, strengths, and limitations of NIRS for the study of principal emotional functions. In the second part, we focus on the actual applications of NIRS in emotional and social research. In this regard, first, we consider some main topics of emotional contexts, such as visual (facial expression) and auditory cues recognition, and social neuroscience field. Second, we discuss the utility to apply NIRS simultaneously to other techniques (electroencephalography, Transcranial Magnetic Stimulation, and functional Magnetic Resonance Imaging) to improve the intrinsic power of such measures. Third, we consider the possible applications of NIRS devices to study specific emotion-related functions (such as connectivity and plasticity applications).     

The temporal stability of the effects induced by the cued reaction time task

The temporal stability of the effects induced by the Cued Reaction Time Task (CRTT) on the orienting of attention was assessed across four weekly sessions. Benefits, costs, and validity effects were computed for each session, and the correlation coefficients between each session were calculated (interindividual stability index). Intraindividual stability indices, the percentage of individuals showing both costs and benefits or the validity effect, were also calculated. The results (based on 41 participants) show a low stability for the effects in which the neutral trials were involved (benefits and costs) but an acceptable reliability for the validity effect, especially when evaluated using the intraindividual index. To maximize the reliability of the data collected using the CRTT, the validity effect seems to be a better probe of spatial orienting of attention.     

Age-related changes in implicit emotion processing

The aim of the present study was to compare the performance of older and younger adults on an emotional priming task. Moreover, a nonemotional priming paradigm was used as a control task to disentangle age-related changes due to emotional processing difficulties from modifications due to a decline of executive inhibitory control abilities. Twenty-two young and 22 older healthy participants completed an emotional priming task and a nonemotional priming task. In the older adult group, reaction times in the emotional priming paradigm were not influenced by any of the prime conditions, whereas both groups exhibited similar facilitation effects induced by the congruent prime in the nonemotional task. The selective lack of an emotional priming effect in older adults shown in this preliminary report suggests that aging-induced changes in the ability to recognize emotions implicitly are directly dependent on emotional processing difficulties and not due to a general age-related modification of cognitive processes.     

Work addiction and presenteeism: The buffering role of managerial support

The current study examined the mediating effect of presenteeism and moderating effect of managerial support in the relation between workaholism and work–family conflict. A sample of 1065 white‐collar employees from an Italian company filled in an online survey and hypotheses were tested using a bootstrapping procedure. Results showed that presenteeism mediated the association between workaholism and work–family conflict. Moreover, the mediating effect of presenteeism was moderated by managerial support: for employees reporting lower levels of support workaholism was stronger related to presenteeism than for those experiencing higher support. Presenteeism, in turn, was related to greater levels of work–family conflict. The present study sheds light into the protective role played by managerial support in preventing workaholic employees from forcing themselves to attend work also when feeling sick. Accordingly, early intervention aimed at buffering the negative association between workaholism and work–family conflict should focus on training managers to develop supportive leadership skills.
