LEADERSHIP STYLES IN SYNCHRONOUS AND ASYNCHRONOUS VIRTUAL LEARNING ENVIRONMENTS

A comparison of the effects of transactional and transformational leadership in synchronous and a synchronous online teamwork was conducted. In the study, groups of four participants interacted in online text chat and online text forum in problem solving tasks. The groups were leaded by a confederate who acted as a transactional or a transformational leader. Satisfaction in the interactions and participations communicative styles were assessed. Results indicated that transformational leadership is more satisfying and cognitive and metacognitive style oriented than transactional leadership that is more participative style oriented

Automatic Influences of Priming on Prosocial Behavior

Literature on the automaticity of social behavior indicates that in some circumstances, priming a concept automatically activates related behavioral schemas. Previous research studies have used priming techniques to increase willingness to help, but most of these have simply measured intention to engage in prosocial behavior rather than real helping behavior. Two different studies investigated the effect of priming the concept of prosocial behavior on real helping behavior. After priming prosociality through a scrambled sentences test, participants were shown to increase their donation rate after a direct request coming from an experimenter's confederate (study 1) and to spontaneously help to a greater extent a girl whose books had fallen on the floor (study 2). The implications of this automatic behavior priming effect are discussed within the theoretical framework of the automatic effect of social perception on prosocial behavior

Priming Effects on Commitment to Help and on Real Helping Behavior

Years of research on bystander apathy have demonstrated that the physical presence of others can reduce the tendency to help individuals needing assistance. Recent research on the implicit bystander effect has suggested that simply imagining the presence of others can lead to less helping behavior on a subsequent unrelated task. The present study was designed to contribute to previous findings on the implicit bystander effect by demonstrating these effects on commitment to help and on real helping behavior, rather than simply on intentions to help. Studies 1a and 1b demonstrate that merely priming participants with the construct of being in a group at Time 1 created significantly less commitment to future helping on a subsequent task at Time 2. Study 2 aimed to extend this effect to behavioral measures and verified that participants exposed to a group prime helped less than those who were exposed to a single-person prime. The implications of these findings for the literature on the bystander effect are discussed

L’ergonomia sociale

Il ruolo speciale degli aspetti sociali all’interno dei contesti di Comunicazione Mediata dal Computer è sempre più evidente. Lo scritto analizza come si giunge a una concettualizzazione dell’ergonomia sociale a partire da modelli teorici consolidati e da prospettive diverse, al fine di giungere a una proposta volta a ricercare la migliore progettazione dei sistemi formativi al fine di avere un apprendimento efficace

Production of He-4 and (4) in Pb-Pb collisions at root(NN)-N-S=2.76 TeV at the LHC

Results on the production of He-4 and (4) nuclei in Pb-Pb collisions at root(NN)-N-S = 2.76 TeV in the rapidity range vertical bar y vertical bar <1, using the ALICE detector, are presented in this paper. The rapidity densities corresponding to 0-10% central events are found to be dN/dy4(He) = (0.8 +/- 0.4 (stat) +/- 0.3 (syst)) x 10(-6) and dN/dy4 = (1.1 +/- 0.4 (stat) +/- 0.2 (syst)) x 10(-6), respectively. This is in agreement with the statistical thermal model expectation assuming the same chemical freeze-out temperature (T-chem = 156 MeV) as for light hadrons. The measured ratio of (4)/He-4 is 1.4 +/- 0.8 (stat) +/- 0.5 (syst). (C) 2018 Published by Elsevier B.V.Peer reviewe

At the Roots of Product Placement: The Mere Exposure Effect

The present study aims to analyze the effect of product placement on attitude change and takes into consideration psychological models of the mere exposure effect. A sample of high school students watched an excerpt from two widely-distributed movies in which several products were shown by using the technique known as product placement. The results indicate that students who saw the commercial brand liked the products more than those who didn’t see it. This effect, in line with the literature on the product placement effect, seems to be independent from the recognition of the brand in the movie excerpt. This study also shows that, in the high involvement condition, one exposure is enough to produce a positive attitude toward the brand
