An Erosion Model of Employee Turnover Based on Network Centrality

An Erosion Model (EM) of employee turnover is introduced to explain the previously observed negative relationship between network centrality and employee turnover. The EM hypothesizes that social support moderates the centrality–turnover relation as those more active in the organization's social network experience less job strain due to esteem provided by work peers. Three EM hypotheses were supported using meta-analytic procedures with significant relations identified between centrality and turnover (k=5, r=.29), social support and centrality (k=7, r=.23), and social support and turnover intentions (k=17, r=.35). Future research for EM expansion and practical applications are proposed.     

The information needs of occupational therapy students: a case study

This article summarises a case study on the information needs of Masters level Occupational Therapy 5 (OT) students at one English university. A mixed methods questionnaire was used to explore motivators for information‐seeking, preferred information resources and barriers inhibiting the satisfaction of information needs. Thirteen recommendations for practice were formulated, focusing on how information professionals can best facilitate OT students’ learning and evidence‐based research skills in preparation for clinical practice. The study was completed by Jane Morgan‐Daniel, who received a Distinction for her work from Aberystwyth University, where she graduated with an MSC in Information and Library Studies in December 2016. She has written this article together with her dissertation supervisor, Hugh Preston. A. M.     

Home advantage in southern hemisphere rugby union: national and international

This study evaluates home advantages both for national (Super 12) and international (Tri-nations) rugby union teams from South Africa, Australia and New Zealand, over the five-year period 2000 - 2004 using linear modelling. These home advantages are examined for statistical and practical significance, for variability between teams, for stability over time and for inter-correlation. These data reveal that the overall home advantage in elite rugby union has a mean of +6.7 points, and that this changes little from year to year. Closer scrutiny nevertheless reveals a high degree of variability. Different teams can and do have different home advantages, which ranges from a low of -0.7 to a high of +28.3 points in any one year. Furthermore, some team home advantages change up or down from one year to the next, by as much as -36.5 to +31.4 points at the extremes. There is no evidence that the stronger teams have the higher home advantages, or that a high home advantage leads to a superior finishing position in the competition.     

Estimating audiences: sampling in television and radio audience research

Cultural consumption is problematic from a number of different perspectives, but certain responses from producers, regulators and commentators depend on the measurement of consumption according to quantitative and qualitative parameters. The reliability of the data can vary widely, not least because in certain areas consumption is invisible to those who would measure it, and so they must make estimates based on assumptions about methodology and sampling techniques. Whereas in auditoria, turnstiles may quite accurately quantify footfall through the premises, and sale or return inspires high levels of confidence in circulation figures for certain types of publication, broadcasters perform to intangible audiences who can be neither counted nor observed en masse. This article considers the appropriateness of sampling techniques used to produce audience research data for the broadcasting industries, for the programmers and advertisers who need detailed ‘knowledge’ about their audiences. It draws on the contextualization in Cultural Trends 45 (Starkey, 2003), which examined the debate around competing methodologies using either innovatory electronic devices for the measurement of consumption or more traditional human recall. The article raises important questions for those who use sampling techniques in the cultural sector and those who would interpret their data.
