How do industrial relations climate and union instrumentality enhance employee performance? The mediating effects of perceived job security and trust in management

Teicher, J ORCiD: 0000-0003-2783-2408In this study, we examine the effects of two key variables associated with union effectiveness on the job performance of employees, and the mechanisms that explain such effects. More specifically, we investigate whether employees' perceptions that their union has a constructive relationship with management (industrial relations climate) and is able to act as an agent for their concerns (union instrumentality) promotes their job performance by enhancing their perceived job security and trust in management. Drawing on three waves of data from 303 employees and their immediate supervisors within 17 private enterprises in China, we find employees' perceptions of union effectiveness influence their job performance by enhancing both their perceived job security and trust in management. These findings are consistent with social exchange theory and conservation of resources theory. This article contributes to the literature by improving our understanding of how unions influence employees' work performance and by explaining how employees' perceptions of the industrial relations climate and union instrumentality influence their job performance. It also sheds light on the important issue of the effectiveness of unions in China, a country where the centrality of the Chinese Communist Party is often considered to have reduced the instrumentality of unions. © 2018 Wiley Periodicals, Inc

Issues in the Development of Research on Inter-role Enrichment

Despite Meissner’s (1971) lament about the “long arm of the job” and its detrimental effects on workers’ home lives, there is a substantial body of research findings, many of which have been reported at the ICWF conferences, supporting the notion that the nature of a job can also be positively related to employees’ well-being and their ability to integrate their work and family lives. Organizations have recognized the importance of work (characteristics) for individuals’ lives and they have started to respond by enriching jobs through providing resources in order to promote life-long learning and enhancement of their employees. This trend follows the spirit of our times in paying attention to individuals’ wishes and needs in designing their jobs in a very contemporary manner, with terms like job crafting, idiosyncratic deals and role adjustments (Grant & Parker, 2009)

A bivalent meningococcal B vaccine in adolescents and young adults

BACKGROUND MenB-FHbp is a licensed meningococcal B vaccine targeting factor H-binding protein. Two phase 3 studies assessed the safety of the vaccine and its immunogenicity against diverse strains of group B meningococcus. METHODS We randomly assigned 3596 adolescents (10 to 18 years of age) to receive MenB-FHbp or hepatitis A virus vaccine and saline and assigned 3304 young adults (18 to 25 years of age) to receive MenB-FHbp or saline at baseline, 2 months, and 6 months. Immunogenicity was assessed in serum bactericidal assays that included human complement (hSBAs). We used 14 meningococcal B test strains that expressed vaccine-heterologous factor H-binding proteins representative of meningococcal B epidemiologic diversity; an hSBA titer of at least 1:4 is the accepted correlate of protection. The five primary end points were the proportion of participants who had an increase in their hSBA titer for each of 4 primary strains by a factor of 4 or more and the proportion of those who had an hSBA titer at least as high as the lower limit of quantitation (1:8 or 1:16) for all 4 strains combined after dose 3. We also assessed the hSBA responses to the primary strains after dose 2; hSBA responses to the 10 additional strains after doses 2 and 3 were assessed in a subgroup of participants only. Safety was assessed in participants who received at least one dose. RESULTS In the modified intention-to-treat population, the percentage of adolescents who had an increase in the hSBA titer by a factor of 4 or more against each primary strain ranged from 56.0 to 85.3% after dose 2 and from 78.8 to 90.2% after dose 3; the percentages of young adults ranged from 54.6 to 85.6% and 78.9 to 89.7%, after doses 2 and 3, respectively. Composite responses after doses 2 and 3 in adolescents were 53.7% and 82.7%, respectively, and those in young adults were 63.3% and 84.5%, respectively. Responses to the 4 primary strains were predictive of responses to the 10 additional strains. Most of those who received MenB-FHbp reported mild or moderate pain at the vaccination site. CONCLUSIONS MenB-FHbp elicited bactericidal responses against diverse meningococcal B strains after doses 2 and 3 and was associated with more reactions at the injection site than the hepatitis A virus vaccine and saline.

Vorapaxar in the secondary prevention of atherothrombotic events

Item does not contain fulltextBACKGROUND: Thrombin potently activates platelets through the protease-activated receptor PAR-1. Vorapaxar is a novel antiplatelet agent that selectively inhibits the cellular actions of thrombin through antagonism of PAR-1. METHODS: We randomly assigned 26,449 patients who had a history of myocardial infarction, ischemic stroke, or peripheral arterial disease to receive vorapaxar (2.5 mg daily) or matching placebo and followed them for a median of 30 months. The primary efficacy end point was the composite of death from cardiovascular causes, myocardial infarction, or stroke. After 2 years, the data and safety monitoring board recommended discontinuation of the study treatment in patients with a history of stroke owing to the risk of intracranial hemorrhage. RESULTS: At 3 years, the primary end point had occurred in 1028 patients (9.3%) in the vorapaxar group and in 1176 patients (10.5%) in the placebo group (hazard ratio for the vorapaxar group, 0.87; 95% confidence interval [CI], 0.80 to 0.94; P<0.001). Cardiovascular death, myocardial infarction, stroke, or recurrent ischemia leading to revascularization occurred in 1259 patients (11.2%) in the vorapaxar group and 1417 patients (12.4%) in the placebo group (hazard ratio, 0.88; 95% CI, 0.82 to 0.95; P=0.001). Moderate or severe bleeding occurred in 4.2% of patients who received vorapaxar and 2.5% of those who received placebo (hazard ratio, 1.66; 95% CI, 1.43 to 1.93; P<0.001). There was an increase in the rate of intracranial hemorrhage in the vorapaxar group (1.0%, vs. 0.5% in the placebo group; P<0.001). CONCLUSIONS: Inhibition of PAR-1 with vorapaxar reduced the risk of cardiovascular death or ischemic events in patients with stable atherosclerosis who were receiving standard therapy. However, it increased the risk of moderate or severe bleeding, including intracranial hemorrhage. (Funded by Merck; TRA 2P-TIMI 50 ClinicalTrials.gov number, NCT00526474.)
