Job-Characteristics Dimensions and Employee Continuance Commitment

Effort towards retaining committed of regular non-academic staff has remained a recurrent concern, indicating that, employees' commitment among university workers, could have been compromised. However, even when investigated into, more extrinsic and less intrinsic factors are applied to determine the commitment. Hence, the study approached this gap from job-characteristics dimensions to employee continuance commitment. The cross-sectional survey research design was adopted and, data collected from 377 regular non-academic staff using validated and reliable copies of a questionnaire. Multiple regression analysis was applied as the inferential statistics. Results from multiple regression analysis conducted found that job-characteristics dimensions had a significant effect on employee continuance commitment [R = 0.726, F(5, 371) = 78.081, p < 0.05]. Also, task identity, task significance, and feedback had a significant positive effect on continuance commitment. On the strength of the statistical findings, it was recommended for management emphasize on task identify, significance and, feedback to enable continuance commitment of non-academic staff.

Three-Year Survival after Transcatheter Aortic Valve Replacement: Findings from the Marshfield Aortic Valve Experience (MAVE) Study

Background: Transcatheter aortic valve replacement (TAVR) is a rapidly evolving treatment for severe aortic stenosis. However, uncertainties exist for optimal valve selection as there are few long-term studies comparing patient survival by valve type.Objective: We hypothesized that self-expandable valves (SEV) would provide a survival advantage over balloon expandable valves (BEV), as SEV continue to expand and might better accommodate to the anatomy of the aortic valve over time.Methods: We examined outcomes according to valve type from a rural tertiary referral center between 2012 and 2017.Results: Out of 269 patients, 77 deaths (28.6%) occurred over the study period with 6 deaths by 1 month post-TAVR and 37 deaths by 1 year post-TAVR. The median observation time for survivors was 21.5 months. The probability of survival at 3 years was 60.7% and 61.9% for patients who underwent treatment with SEV and BEV, respectively. There was no statistically significant difference in overall patient survival with or without adjustment for factors such as age, sex, race, and aortic valve area. Additionally, in a secondary analysis restricted to those patients treated in later years (2015-2017) survival among patients with BEV appeared superior (HR=0.456, P=0.015).Conclusion: Patients who underwent TAVR at a rural medical center with SEV showed similar survival compared to those who received a BEV. Superior survival was observed among those who received BEV versus SEV between 2015 and 2017
