COLDz: Karl G. Jansky Very Large Array discovery of a gas-rich galaxy in COSMOS

The broad spectral bandwidth at mm and cm-wavelengths provided by the recent upgrades to the Karl G. Jansky Very Large Array (VLA) has made it possible to conduct unbiased searches for molecular CO line emission at redshifts, z > 1.31. We present the discovery of a gas-rich, star-forming galaxy at z = 2.48, through the detection of CO(1-0) line emission in the COLDz survey, through a sensitive, Ka-band (31 to 39 GHz) VLA survey of a 6.5 square arcminute region of the COSMOS field. We argue that the broad line (FWHM ~570 +/- 80 km/s) is most likely to be CO(1-0) at z=2.48, as the integrated emission is spatially coincident with an infrared-detected galaxy with a photometric redshift estimate of z = 3.2 +/- 0.4. The CO(1-0) line luminosity is L'_CO = (2.2 +/- 0.3) x 10^{10} K km/s pc^2, suggesting a cold molecular gas mass of M_gas ~ (2 - 8)x10^{10}M_solar depending on the assumed value of the molecular gas mass to CO luminosity ratio alpha_CO. The estimated infrared luminosity from the (rest-frame) far-infrared spectral energy distribution (SED) is L_IR = 2.5x10^{12} L_solar and the star-formation rate is ~250 M_solar/yr, with the SED shape indicating substantial dust obscuration of the stellar light. The infrared to CO line luminosity ratio is ~114+/-19 L_solar/(K km/s pc^2), similar to galaxies with similar SFRs selected at UV/optical to radio wavelengths. This discovery confirms the potential for molecular emission line surveys as a route to study populations of gas-rich galaxies in the future

Antecedents of trust across foci: a comparative study of Turkey and China

Instead of importing Western models of interpersonal trust, we adopted a qualitative approach to understand trust relationships from indigenous cultures' perspectives. We examined trust relationships directed at different foci in the organization (supervisor, peer, and subordinate) in two different countries, Turkey and China. Semi-structured interviews were conducted with 30 Turkish and 30 Chinese employees working for a variety of large-scale organizations located in Istanbul, Turkey and Shenzhen, China. We report the content analysis of trust-building critical incidents narrated by the respondents. While the general antecedents of Ability, Benevolence, and Integrity were found to exist in both countries, Benevolence, with its culture-specific manifestations, played a very important role in trust-building across multiple foci in both countries. We also found that trust relationships in these two contexts tended to go beyond the professional domain, and to involve sharing of personal time, information, and space. Drawing on this evidence, we propose a trust-building process that is more affective in nature and which straddles both work and non-work domains

Proactivity directed toward the team and organization : the role of leadership, commitment and role-breadth self-efficacy

Employees' proactive behaviour is increasingly important for organizations seeking to adapt in uncertain economic environments. This study examined the link between leadership and proactive behaviour. We differentiated between organizational leadership and team leadership and proposed that transformational leadership by team leaders would enhance commitment to the team, which would predict team member proactivity. In contrast, transformational leadership by leaders of the organization would enhance commitment to the organization, which we expected to predict organization member proactivity. Transformational leadership on both levels was expected to increase employees' role-breadth self-efficacy, the confidence necessary to engage in proactive behaviour. Our results demonstrate the importance of leadership as an antecedent of proactive work behaviour and suggest that leadership at different levels influences proactivity via different mediators. Transformational team leaders seem to facilitate proactivity by increasing employees' confidence to initiate change. Transformational organizational leaders on the other hand increase proactivity by enhancing employees' commitment to the organization

The Psychosocial Work Environment, Employee Mental Health and Organizational Interventions: Improving Research and Practice by Taking a Multilevel Approach

Although there have been several calls for incorporating multiple levels of analysis in employee health and wellbeing research, studies examining the interplay between individual, workgroup, organizational and broader societal factors in relation to employee mental health outcomes remain an exception rather than the norm. At the same time, organizational intervention research and practice also tends to be limited by a single-level focus, omitting potentially important influences at multiple levels of analysis. The aims of this conceptual paper are to help progress our understanding of work-related determinants of employee mental health by: (i) providing a rationale for routine multilevel assessment of the psychosocial work environment; (ii) discussing how a multilevel perspective can improve related organizational interventions and (iii) highlighting key theoretical and methodological considerations relevant to these aims. We present five recommendations for future research, relating to using appropriate multilevel research designs, justifying group level constructs, developing group-level measures, expanding investigations to the organizational level, and developing multilevel approaches to intervention design, implementation and evaluation

Distributed Leadership and Employee Cynicism: Trade unions as joint change agents

The themes of change management and workplace partnership continue to attract significant academic interest – albeit within discreet literatures. Drawing on longitudinal, qualitative data in a heavy engineering organization this article details how a collaborative partnership between management and trade unions, encompassing a distributed’ leadership format, was configured to enhance organizational capacity for change in the context of significant employee cynicism. Bridging human resource management/organizational behaviour and industrial relations perspectives the works makes a theoretical contribution to our understanding of the factors underpinning the successful implementation of workplace partnership and the utilisation of distributed leadership configurations. More generally the work informs leadership theory through its scrutiny of distributed leadership in situations of high conflict

Discursive positioning and planned change in organizations

This study uses discursive positioning theory to explore how planned change messages influence organizational members’ identity and the way they experienced organizational change. Based on an in-depth case study of a home healthcare and hospice organization that engaged in a multiyear planned change process, our analysis suggests that workers experienced salient change messages as constituting unfavorable identities, which were associated with the experiences of violation, recitation, habituation, or reservation. Our study also explores the way discursive and material contexts enabled and constrained the governing board’s change messages as they responded to external and internal audiences. We highlight the importance of viewing messaging as a process of information transfer as well as discursive construction, which has important implications for the way change agents approach issues of sense making, emotionality, resistance, and materiality during planned change processes.Yeshttps://us.sagepub.com/en-us/nam/manuscript-submission-guideline

Psychological attachment to the group: Cross-cultural differences in organizational identification and subjective norms as predictors of workers' turnover intentions

Two studies wed the theory of reasoned action, social identity theory, and Ashforth and Mael's work on organizational identification to predict turnover intentions in Japanese and British commercial and academic organizations. In both studies and in both countries, the authors expected and found that identification with the organization substantially and significantly predicted turnover intentions. Attitudes predicted intentions only in Study 2, and subjective norms significantly predicted intentions across both studies. The authors hypothesized that subjective norms would be a significantly stronger predictor of turnover intentions in a collectivist setting. This prediction was supported. Although social identity is strongly associated with turnover intentions across both cultures, the subjective normative aspects of group membership are significantly more strongly associated in the Japanese organizations
