Frequency and Density-Dependent Selection on Life-History Strategies - A Field Experiment
2008
Negative frequency-dependence, which favors rare genotypes, promotes the maintenance of genetic variability and is of interest as a potential explanation for genetic differentiation. Density-dependent selection may also promote cyclic changes in frequencies of genotypes. Here we show evidence for both density-dependent and negative frequency-dependent selection on opposite life-history tactics (low or high reproductive effort, RE) in the bank vole (Myodes glareolus). Densitydependent selection was evident among the females with low RE, which were especially favored in low densities. Instead, both negative frequency-dependent and density-dependent selection were shown in females with high RE…
An investigation into voluntary employee turnover and retention factors in sport organizations
2017
In the past few decades, sport organizations have undergone a major change in their management practices as they are expected to become more and more formal and professional-like. Despite this pressure, human resource managers should give more attention to the retention function in human resource management systems. As employees are the lifeline of sport organizations, much emphasis should be placed on preventing their voluntary turnover. Utilizing qualitative and inductive grounded theory building methods this study aims to provide invaluable information to sport managers about why employees leave or remain in sport organizations. Given the scant research on turnover and retention in sport…
Impact assessment of a solar powered water treatment project
2015
Water treatment technologies are seen as the best alternative to be considered for adoption in developing countries where access to portable water supply that is free of pathogens is yet a challenge. This study intended to assess impact brought forth by a project, which employed a water treatment technology in rural settings of Morogoro Region in Tanzania. The project used solar photovoltaic panels to trap solar energy, converted to mechanical power to treat water with the help of sterilization ultraviolet membrane. A comparative analysis was used as an assessment framework to study impacts of the project with respect to the quality of approach used during the project life cycle. Determinan…
The Psychometric properties of the resilience scale (RS-14) in Lithuanian adolescents
2021
In the current study, we provided the evidence of satisfactory validity of the RS-14 scale in the Lithuanian adolescents’ sample (N = 1299; Mage = 14.24; SDage = 1.26), based on its internal structure, and relations to other variables. The results of the study indicated an acceptable model fit for a single-factor structure of the scale with a high internal consistency (McDonald’s omega = 0.89). We also confirmed the scalar measurement invariance across groups of adolescents in terms of their age (i.e., early and middle adolescence) and mental health profile as well as partial scalar gender invariance. Adolescents characterized by high levels of socio-emotional problems reported lower levels…
