Effectiveness of Recruitment and Selection Practices in Public Sector Higher Education Institutions: Evidence from Ghana

The purpose of this paper is to assess the recruitment and selection practices of public sector higher education institutions in Ghana. The research employed quantitative research approach with a descriptive survey design. Questionnaire was used to collect data from 128 respondents. Stratified and simple random sampling techniques were used to select the sample from the targeted population. Data processing was done using SPSS version 22. Results of the analyses showed, inter alia, the following; (a) Public sector higher education institutions in Ghana predominantly relies on recommendation as its main mode of employment; (b) Identification of available vacancies and delay in feedback after interviews were the two main challenges with the public sector higher education institutions in Ghana recruitment and selection practices. It is recommended that employee referrals (recommendation) though a good idea should be reduced, public sector higher education institutions in Ghana should make use of adverts (either print or electronic or both) in publicising its vacant positions

Time domain studies of training effects in Co/Cu/FeNi/FeMn spin valves

The recovery and the relaxation behaviors of the exchange bias (HE) in a Co/Cu/FeNi/FeMnspin valve has been studied via point contact technique with high field scan rates ranging from 1050 to 13500 Oe/s. The evolution of the exchange bias with the number of field cycles(n) shows a one over the square root of (n) dependence as against ln(n) in a previous study. A recovery of the exchange bias when the field cycling is stopped has been observed and the recovery ratio (R) is found to be a function of the logarithm of the recovery time (log(t)) in agreement with previous studies. The relaxation time of the exchange bias is estimated to be 6.62, 20.85, 43.10, 109.02, and 297.24 s for 13500, 5400, 2700, 1350, and 1050 Oe/s respectively. The one over the square root of (n) dependence of HE and the log (t) dependence of R have been discussed using thermal activation model
