Employee voice at work: the role of employees’ gender,self-efficacy beliefs,and leadership

ABSTRACT

Building on social role theory, we investigated the association between gender and employee voice (employees’ speaking up in a challenging but constructive way about work-related issues) in a typically male-dominated sector. In two field studies in the logistics context, we tested how and when gender is related to employee voice. In Study 1 (N = 132), we examined whether the gender-voice association is mediated by general self-efficacy beliefs. In Study 2 (N = 99), we replicated the indirect effect of gender on employee voice via general self-efficacy beliefs and investigated whether this indirect effect is contingent on supportive leadership. Using path analytical procedures, we found a significant indirect effect moderated by supportive leadership: At low and medium levels of supportive leadership, women reported less self-efficacy than men, which in turn resulted in less voice. At high levels of supportive leadership, the indirect effect was nonsignificant. Our studies contribute to research on the mechanisms and boundary conditions of gender’s influence in the employee voice process and have practical implications for leaders in male-dominated working contexts who want to encourage their female employees to speak up about work-related issues.     

Speaker identification using multi-modal i-vector approach for varying length speech in voice interactive systems

The development in the interface of smart devices has lead to voice interactive systems. An additional step in this direction is to enable the devices to recognize the speaker. But this is a challenging task because the interaction involves short duration speech utterances. The traditional Gaussian mixture models (GMM) based systems have achieved satisfactory results for speaker recognition only when the speech lengths are sufficiently long. The current state-of-the-art method utilizes i-vector based approach using a GMM based universal background model (GMM-UBM). It prepares an i-vector speaker model from a speaker’s enrollment data and uses it to recognize any new test speech. In this work, we propose a multi-model i-vector system for short speech lengths. We use an open database THUYG-20 for the analysis and development of short speech speaker verification and identification system. By using an optimum set of mel-frequency cepstrum coefficients (MFCC) based features we are able to achieve an equal error rate (EER) of 3.21% as compared to the previous benchmark score of EER 4.01% on the THUYG-20 database. Experiments are conducted for speech lengths as short as 0.25 s and the results are presented. The proposed method shows improvement as compared to the current i-vector based approach for shorter speech lengths. We are able to achieve improvement of around 28% even for 0.25 s speech samples. We also prepared and tested the proposed approach on our own database with 2500 speech recordings in English language consisting of actual short speech commands used in any voice interactive system.     

Linking individuation and organizational identification: Mediation through psychological safety

ABSTRACT

This paper examines how individuation, a view that organizational members are all unique individuals, induces a perception of psychological safety and how perception of psychological safety, in turn, increases one’s organizational identification. Results from 66 respondents in Study 1 provided first support for the proposed mechanism. In Study 2, data collected from 176 employees in work organizations also provided evidence for this mediation model. It was found in both studies that individuation has a significantly positive association with the perception of psychological safety such that the more employees view individual members of the organization as unique individuals, the more likely they perceive that their organization is a safe environment for self-expression. Furthermore, perception of psychological safety was found to serve as a mediator linking individuation and organizational identification.     

Friendships in middle childhood: Links to peer and school identification,and general self-worth

Children's friendships are important for well-being and school adjustment, but few studies have examined multiple indices of friendships together in middle childhood. The current study surveyed 7- to 11-year-olds (n = 314) about their friendships, best friendships, friendship quality and indices of self-worth, identification with peers, and identification with school. Peer relationships were positively related to self-worth, but not identification with peers or school. Best friendship quality moderated the relationship between number of reciprocated friendship nominations and self-worth. Children with a reciprocated best friend had higher friendship quality and peer identification than others. Where best friendship was reciprocated, the relationship with identification with peers was mediated via positive friendship quality. The results suggest that friendship reciprocity is particularly relevant for children's self-worth and identification with peers. The findings are discussed in relation to the importance of fostering the development of reciprocated friendships.

Statement of contribution

What is already known on this subject?

• Friendships are related to well-being, school relations, and how young people feel about their peers at school.
• Friendship quality may be important in moderating the relationship between peer relations and adjustment.

What does this study add?

• Various aspects of friendships are studied simultaneously with younger children than much previous research.
• Reciprocated best friendships were better quality than partial or non-reciprocated best friendships.
• Friendship reciprocity was most relevant for children's self-worth and peer identification.

     

The origins of party identification and its relationship to political orientations

An established position, long recognized in the literature, maintains that political party identification (PID) arises mainly from familial socialization and has a major impact on political outlooks and behaviors. An alternative view, also entrenched in the literature, holds that the direction of causation may go the other way, with political orientations influencing PID insofar as individuals seek out parties that match their ideological viewpoints. Here we use univariate and multivariate twin modeling to examine the underlying etiology assumed by those two positions, and introduce a new perspective that may help researchers make sense of PID, political orientations, and the relationships between them. Our findings indicate that: (1) PID is substantially heritable; and (2) there is empirical support for a model in which genetic and environmental factors influence political orientations, which in turn affect PID.     

The Role of Problem Construction in Creative Production

This paper provides an overview of theory and research regarding problem construction and identification. Specifically, the paper reviews a theoretical model of processes associated with problem construction and empirical evidence in relation to the model. Finally, the paper reviews the literature on team problem construction.
