This commentary focuses on the measurement of temporal dimensions at different levels of analysis. In particular, it examines the measures that are available for various levels of analysis for four temporal dimensions: polychronicity, speed, punctuality, and temporal depth. The discussion is meant to spur additional research using reliable and valid temporal measures at multiple levels of analysis.

Drawing from findings in sociology and anthropology on time as a symbol of status, this paper examines the role that status differentials affect how group members internally align the pace of their activities over time (group synchronization). We examine the psychological process of group synchronization from the perspective of the individual, the nature of status differentials in work groups, and how one’s status within a group affects a person’s willingness to adjust the timing of his/her activities to match other people’s timing. We then identify three types of status structures within work groups and analyze how each affects the group’s ability to synchronize. We close by considering the implications of our approach for better understanding temporal dynamics in work groups.

In class action antitrust litigation, the standards for acceptable economic analysis at class certification have continued to evolve. The most recent event in this evolution is the United States Supreme Court’s decision in Comcast Corp. v. Behrend, 133 S. Ct. 1435 (2013). The evolution of pre-Comcast law on this topic is presented, the Comcast decision is thoroughly assessed, as are the standards for developing reliable economic analysis. This article explains how economic evidence of both antitrust liability and damages ought to be developed in light of the teachings of Comcast, and how liability evidence can be used by economists to support a finding of common impact for certification purposes. In addition, the article addresses how statistical techniques such as averaging, price-dispersion analysis, and multiple regressions have and should be employed to establish common proof of damages.

Existing theoretical and empirical evidence is inconclusive concerning the comparative performance of labor-managed firms (LMFs) and conventional firms. By assembling and analyzing new data for a sample of 51 conventional firms and 26 producer cooperatives in the Italian construction industry during the period 1981–1989 we provide additional evidence. Except for organizational form, the cooperatives in our sample are fairly comparable to our conventional firms. Based on our production function estimates, and unlike some previous econometric studies, we find no significant productivity advantage of cooperatives over conventional firms. Our ordinary least squares (OLS) point estimates generally indicated that output would be lower in a cooperative than in an otherwise identical conventional firm. The only statistically significant measure of financial and decision-making participation is collective reserves. We conclude by offering some possible explanations for why our results may differ from some previous findings, especially those for Italian producer cooperatives. In particular we suggest that research methods that are new to the study of cooperatives are needed to help to resolve these questions.

In this chapter, the authors focus on a range of Australian news articles selected for their relevance to key themes in the area of child abuse and examine two high profile cases of child abuse deaths that were extensively reported on by the media and led to system reform. Challenges for media reporting on child abuse in Australia including a changing media landscape, lack of available child abuse data and lack of publicly available serious case reviews are discussed. The authors argue that there is a need for attention to be paid to children's resistance and agency in the context of violence and abuse to counter the objectification of children and uphold their rights. Following Finkelhor (2008), the authors argue that media reporting on child abuse in Australia reflects a general approach to child abuse that is fragmented, with different types of abuse viewed as separate from one another, and call for a more integrated understanding of child abuse. The authors highlight the complexity of media responses to child abuse in Australia, noting that while the social problem of child abuse can be misrepresented by the media, media reporting has also triggered significant systemic reform and advocated for children in cases where other systems failed them.
