On the effects of authority on peer motivation: Learning from Wikipedia

Research Summary: We investigate the conditions under which authority can be deployed without reducing subordinate motivation. We show that lateral authority, the legitimacy to resolve task‐specific problems, is welcomed by members of an organization in the resolution of coordination conflicts, the more so (a) the fiercer the conflict to be resolved, (b) the higher the competence‐based status of the authority, (c) the lower the tenure of, and (d) the more focused the organizational members are. Analyzing the discussion behavior of members of Wikipedia between 2002 and 2014, we corroborate our allegations empirically by analyzing 642,916 article–discussion pages. Our findings, obtained for a modern collective production community, provide learning opportunities for how traditional organizations may want to govern activities of their idiosyncratically motivated staff. Managerial Summary: When managers use their (legitimate) power to take decisions on behalf of their staff, they risk setting back employees and making them detach from the firm. This danger is particularly salient whenever highly motivated teams of staff autonomously work on corporate problems and are used to governing themselves. Examples range from skunkwork initiatives within traditional firms to entire team‐based organizations, such as Valve or Zappos. When and how managers can add value by resolving conflicts within and across these teams once their self‐organization fails is what we study in this article. Inspired by data from Wikipedia, we suggest that managers should not intervene prematurely, benefit from visible competence, and are respected most for their actions by specialized peers who recently joined the organization.     

Economic burden of amyotrophic lateral sclerosis in the United Kingdom

Abstract

To assess the economic burden of amyotrophic lateral sclerosis (ALS) in the United Kingdom, yearly direct medical costs were determined for four defined ALS health states (mild, moderate, severe and terminal disease stages). Resource utilisation patterns for each health state were obtained from United Kingdom neurologists and local costs (1996/97) were attached to the resources. The annual direct cost of the health states increased from £1185.20 in mild disease to £3127.51 in the terminal state. Hospitalisation was a major contributor to total cost in mild (43.3%), severe (31.6%) and terminal (45.1%) states. In contrast, in moderate disease the impact of hospitalisation was minimal (0.8%) compared to physician remuneration costs (59%). The economic burden of ALS is therefore directly related to the severity of the disease. The study identifies the major cost drivers in current ALS care and provides a means for determining how potential therapeutic interventions might affect the overall cost of the disease.

A Typology of Partial-Order: The Case of Drug Use in Israel

A frequent variety of typology is that which results when a given population is classified simultaneously by several criteria, the categories of each criterion being ordered in a sense common to all the criteria. Such simultaneous orderings automatically define a partial order typology.The empirical problem is to ascertain the dimensionality and the substantive meaning of the partial order. This is illustrated here by characterization of the Jewish population of Israel by the frequencies of use of a variety of drugs. The data analysis approach adopted is that of Partial Order Structuple (Scalogram) Analysis (POSA). The particular computer program used is POSAC (POSA with Base Coordinates).The analysis revealed that it is possible to portray the distinct profiles (structuples) of the respondents according to drug use in a two-dimensional space, with a substantive regularity relating both to legal (pain relievers) and illegal drugs (marijuana, methadon). This space also serves as a basis for discriminant analysis for age as an external background variable.

Talent management and global competition for top talent: A co‐opetition‐based perspective

In an age of competition for top talent, lateral hiring or personnel poaching has flourished not just between rivals, but also among allies transcending across national borders. This article integrates the literature on lateral hiring and co‐opetition to develop a “novel” perspective of the co‐opetition‐based view of lateral hiring. A conceptual framework was developed to account for conditions under co‐opetition setting in different markets. Contrary to the popular belief that poaching from rivals is more beneficial, the present research demonstrates that poaching from allies may be more beneficial in mitigating the “winner's curse.” Indeed, poaching in the collaboration domain is characterized by greater access to information about the target employee before job change. Lateral hiring from allies in foreign markets can also be more beneficial given the potentially moderate stigma attached compared with those from domestic markets. The implications for firms and strategic human resource management literature are examined.
