Modelling the acceptance of fully autonomous vehicles: A media-based perception and adoption model

As the technology matures, fully autonomous vehicles (AVs) are on the corner. This calls for exploring the factors that might influence potential users’ perception and acceptance of AVs. Limited existing studies related to acceptance modeling investigated the effects of media and human on fully AVs’ beliefs. Hence, a media-based perception and adoption model (MPAM) is developed to investigate how information and opinion (from mass media and social media) affect human self-perception (including self-efficacy and subjective norms) and product value perception (including perceived usefulness and risks), which in turn drive users’ adoption intention to private AVs and public AVs as well. Through a questionnaire survey, 355 samples from two universities were collected in Beijing. The structural equation model results confirm that media channels have salient effects on consumer and product with different emphases. Mass media enhances potential users’ self-efficacy of fully AVs, while social media strengthens subjective norms. Both usefulness and risks of AVs are perceived simultaneously via mass media, whereas risks perception can be significantly eliminated by social media. All constructs of user’s self-perception and product perception are verified to drive users’ intention to using AVs and public AVs. Besides the theoretical and modeling contributions, practical implications are provided for the marketers and stakeholders in the early stages of AVs launch.

Defying conventional wisdom: A meta-analytical examination of the differences between demographic and job-related diversity relationships with performance

Conventional wisdom in the diversity literature holds that job-related dimensions of diversity are the domain of positive performance, whereas demographic dimensions of diversity are the domain of negative performance effects. In a meta-analysis (N = 146 studies, 612 effect sizes), we show that this conclusion may be based on rater biases; it does not apply to studies involving more objective assessments of performance, assessments that cannot be influenced by knowledge of a team’s composition. We also show that the influence of job-related diversity is moderated by task complexity and that job-related diversity is more positively related to innovative performance than to in-role performance. We discuss how these results invite a reconsideration of the role of the job-related/demographic diversity distinction and provide suggestions on how to further advance our understanding of diversity’s effects.     

Les gestionnaires tunisiens au cœur de la tourmente postrévolution : entre injustice et empowerment psychologique

The purpose of this research is to comprehend the reasons that arouse employee's psychological empowerment against organizational injustice. Based on this complex problematic, our approach is articulated around two central sectors. We proposed a conceptual framework of the researches related to organizational injustice and psychological empowerment for a better understanding of the mechanisms at work in their genesis. The qualitative exploratory investigation led in the mechanical and electric industrial sector in Tunisia underlined that a set of intra and extraorganizational determinants impact considerably the dynamic between injustice and psychological empowerment. The results clearly underline that contextual particularities are a catalyst of psychological empowerment.     

The impact of feedback from job and task autonomy in the relationship between dispositional resistance to change and innovative work behaviour

Building on an interactionist approach, the present study investigated the moderating role of two task design characteristics, namely task autonomy and feedback from job, in the relationship between dispositional resistance to change and innovative work behaviour. Consistent with a trait activation perspective, it was specifically hypothesized that dispositional resistance to change would have a stronger, positive association with innovative performance when autonomy and feedback were high than when they were low. In a sample of 270 employees from the public sector, task autonomy was found to significantly interact with both composite resistance to change and with three of the four dimensions (routine seeking, short-term thinking, and emotional reaction). Simple slope analyses specifically revealed that individuals high in short-term thinking and emotional reaction exhibited positive relationships with innovative behaviour only in the case of high task autonomy, whereas in the case of low autonomy the relationship was nonsignificant. Furthermore, feedback from job was found to moderate the relationship between overarching dispositional resistance to change, short-term thinking, and emotional reaction, on one hand, and innovative performance, on the other, such that a positive and significant association emerged only in the case of high feedback.     

Antecedent variables of innovation behaviors in organizations: Differences between men and women

IntroductionRelevance of innovation behaviors for organizational success led to study its main individual, job-related and organizational antecedents. Moreover, research on differences in innovation between men and women showed inconclusive results. Ambidexterity (Bledow, Frese, Anderson, Erez, & Farr, 2009) and Zhou and Hoever (2014) call for combining contextual and personal characteristics in innovation research suggest that pathways and variables leading to innovation between men and women could be different.Objective(s)This study aims to analyze if men and women differ in the main antecedents for innovative behaviors. Thus, a moderating effect of gender on the relationship between innovative behaviors and their main antecedent variables is hypothesized. Results are of interest for promoting innovation and empowering women at work context.MethodIn a sample of 458 employees from 16 Spanish companies, we carried out hierarchical regression analyses on innovation behaviors, including as main antecedents academic level, proactive personality, job demands, organizational commitment, HR practices addressed to participation, and transformational leadership. In addition, interaction terms between gender and such antecedents were entered in regression analysis.ResultsProactive personality, HR participation practices, inspirational motivation, job demands and academic level significantly predicted innovative behaviors at their different phases. Moreover, gender moderated the relationship between generation of new ideas with academic level and organizational commitment, and between promotion of ideas with job demands and idealized influence. Organizational commitment promoted generation of ideas among women but not among men, whereas idealized influence is detrimental for women. Reversely, higher job demands stimulate promotion of ideas among men but were detrimental for innovation among women.ConclusionOur results suggest that innovation among women seems to be more sensitive to the influence of leadership and require more social support, whereas higher job demands are detrimental. These results suggest that innovation is more related to intrinsic variables (as self-confidence, empowerment and social processes) among women, whereas for men, it seems to be more related to work demands. Results could help companies to stimulate innovation, between both men and women.

Do captive mandrills invent new gestures?

Studies of intraspecific behavioral variability have documented cases where behaviors are present in some populations or groups but are absent in others. In some cases these differences cannot be explained by recourse to environmental or genetic variation, and may instead represent “traditions”. Despite many examples of animal traditions in acoustic communication, relatively few examples exist of gestural traditions. Here I report on a study of communication across eight captive groups of mandrills (Mandrillus sphinx) in which a prominent gesture (Hand extension) was unique to two groups. Habitat variability, genetic differences, and sampling bias were not sufficient to account for the gesture’s limited distribution across the study groups. Within the two groups where the gesture did occur only the juveniles in the group performed it, consistently directing it toward adults. Quantitative analysis of the contexts and responses associated with the gesture suggested that juveniles utilized it to provoke adults. Moreover, the gesture appeared to minimize the risk juveniles incurred while inciting adults, suggesting that repeated social interactions shaped the gesture’s form. Interestingly, both the groups where the gesture emerged contained few juveniles. With limited play partners, these juveniles may have resorted to harassing adults as an alternative social play outlet. The creation of this novel gesture may thus be due to the combined influence of a shortage of play partners and of the increased free time for playful social exploration afforded by captivity. Although juveniles frequently “eavesdropped” on dyadic interactions involving the gesture and would subsequently initiate an interaction with the recipient of the gesture, there was no definitive evidence for social transmission; the gesture could instead have been independently invented by each juvenile.
