ILR Impact Brief - Affective Commitment Links Human Resource Practices and Voluntary Turnover

[Excerpt] Motivation- and empowerment- enhancing human resource (HR) practices are positively associated with employees’ collective emotional attachment to, and identification with, a company and its goals; this affective commitment, in turn, is negatively associated with the aggregate of employee decisions to exit an organization. Thus, collective affective commitment mediates the relationship between these two sets of HR practices and voluntary turnover. Practices that enhance workforce skills, however, are not mediated by collective affective commitment; rather, they are directly and positively associated with increased voluntary turnover

The Impact of Human Resource Practices on Business-Unit Operating and Financial Performance

This study examined the impact of HR practices and organizational commitment on business-unit operating performance and profitability. Using a predictive design with a sample of 50 autonomous business-units within the same corporation, the study revealed that both organizational commitment and HR practices were significantly related to operational measures of performance as well as operating expenses and pre-tax profits

High Performance HR Practices And Customer Satisfaction: Employee Process Mechanisms

This research examined organizational commitment and customer focus as mediators between HR practices and customer satisfaction of seventy-one work units from twenty-five business units from a single firm in the food service industry. Customer satisfaction was assessed by ratings from multiple customers eighteen months after HR practices and process mechanisms were assessed from unique groups of employee respondents. Results suggest that employee commitment and customer focus partially mediate the relationship between HR practices and customer satisfaction

Beginning to Unlock the Black Box in the HR Firm Performance Relationship: The Impact of HR Practices on Employee Attitudes and Employee Outcomes

Theoretical models in strategic human resource management research commonly include employee attitudes and behaviors as key mediating links between human resource practices and firm performance. However, almost all empirical SHRM work to date has ignored the mediating hypothesis and merely examined the direct relationship between HR practices and firm outcomes. The purpose of this study is to test the relationship between HR practices and employee attitudes and behaviors. Using a sample of 174 independent work groups, we examined the relationship between HR practices and collective behaviors (turnover and absenteeism) mediated by collective attitudes (job satisfaction and commitment). Results indicate attitudes partially mediate the relationship between HR practices and employee behaviors. The direct and indirect relationships identified in this study support the notion that attitudes and behaviors play a mediating role between HR practices and firm outcomes. These findings illustrate the varying impacts of HR practices and the importance of utilizing multilevel theory and methods

HR Practices and Customer Satisfaction: The Mediating Link of Commitment

This research examined organizational commitment as a mediator between HR practices and customer satisfaction of 35 job groups from 13 service firm business units. Both commitment level and consensus were predicted to influence customer satisfaction. Results found that commitment level mediated the relationship between HR practices and customer satisfaction

Measurement Error in Research on Human Resources and Firm Performance: Additional Data and Suggestions for Future Research

Gerhart and colleagues and Huselid and Becker recently debated the presence and implications of measurement error in measures of human resource practices. This paper presents data from three more studies, one of large organizations from different industries at the corporate level, one from commercial banks, and the other of autonomous business units at the level of the job. Results of all three studies provide additional evidence that single respondent measures of HR practices contain large amounts of measurement error. Implications for future research are discussed

Herbal remedy clinical trials in the media: a comparison with the coverage of conventional pharmaceuticals

<p>Abstract</p> <p>Background</p> <p>This study systematically compares newspaper coverage of clinical trials for herbal remedies, a popular type of complementary and alternative medicine, with clinical trials for pharmaceuticals using a comparative content analysis. This is a timely inquiry given the recognized importance of the popular press as a source of health information, the complex and significant role of complementary and alternative medicine in individual health-care decisions, and the trend toward evidence-based research for some complementary and alternative medical therapies. We searched PubMed for clinical trials, Lexis/Nexis for newspaper articles in the UK, US, Australia/New Zealand, and Factiva for Canadian newspaper articles from 1995 to 2005. We used a coding frame to analyze and compare 48 pharmaceutical and 57 herbal remedy clinical trials as well as 201 pharmaceutical and 352 herbal remedy newspaper articles.</p> <p>Results</p> <p>Herbal remedy clinical trials had similar Jadad scores to pharmaceutical trials but were significantly smaller and of shorter duration. The trials were mostly studies from Western countries and published in high-ranking journals. The majority of pharmaceutical (64%) and herbal remedy (53%) clinical trials had private sector funding involvement. A minority declared further author conflicts of interest. Newspaper coverage of herbal remedy clinical trials was more negative than for pharmaceutical trials; a result only partly explained by the greater proportion of herbal remedy clinical trials reporting negative results (<it>P </it>= 0.0201; <it>χ</it>²= 7.8129; degrees of freedom = 2). Errors of omission were common in newspaper coverage, with little reporting of dose, sample size, location, and duration of the trial, methods, trial funding, and conflicts of interest. There was an under-reporting of risks, especially for herbal remedies.</p> <p>Conclusion</p> <p>Our finding of negative coverage of herbal remedy trials is contrary to the positive trends in most published research based primarily on anecdotal accounts. Our results highlight how media coverage is not providing the public with the information necessary to make informed decisions about medical treatments. Most concerning is the lack of disclosure of trial funding and conflicts of interest that could influence the outcome or reporting of trial results. This lack of reporting may impact the medical research community, which has the most to lose by way of public trust and respect.</p

Effects of antiplatelet therapy on stroke risk by brain imaging features of intracerebral haemorrhage and cerebral small vessel diseases: subgroup analyses of the RESTART randomised, open-label trial

Background Findings from the RESTART trial suggest that starting antiplatelet therapy might reduce the risk of recurrent symptomatic intracerebral haemorrhage compared with avoiding antiplatelet therapy. Brain imaging features of intracerebral haemorrhage and cerebral small vessel diseases (such as cerebral microbleeds) are associated with greater risks of recurrent intracerebral haemorrhage. We did subgroup analyses of the RESTART trial to explore whether these brain imaging features modify the effects of antiplatelet therapy
