SELFING ABILITY AND MALE STERILITY IN SENECIO VERNALIS WALDST. ET KIT. (ASTERACEAE) FROM ISRAEL

1994

Two major findings relating to the breeding system of Senecio vernalis from Israel are reported. First, isolation experiments failed to confirm the existence of a widespread, truly self-compatible and predominantly self-pollinating breeding system in Israeli populations of S. vernalis. However, a single S. vernalis plant derived from a natural stand at Jerusalem was found to be self- compatible and strongly self-pollinating. In its progeny, there were signs of inbreeding depression commonly associated with selfed offspring of outbreeding species. Selfing ability ratios in this progeny indicate a single dominant gene for selfing ability in S. vernalis. The implications of these observations …

Coaches’ implementation strategies in providing social support to Singaporean university athletes: A case study

2019

Coaches are effective providers of social support to their athletes. Although sport-specific measures of social support have been developed to better understand athletes’ perceptions of available support, limited amount of research has addressed how sport coaches implement specific social support strategies. The purpose of this study was to examine university coaches’ implementation strategies in providing various forms of social support to their athletes. A total of eight sport coaches from team and individual sports (four from each sport) were purposefully selected for this study. Coaches were individually interviewed. The interview transcripts were analysed using a thematic analysis. Th…

Coach-created motivational climate and athletes’ adaptation to psychological stress : Temporal motivation-emotion interplay

2019

This two-wave study investigated the temporal interplay between motivation and the intensity and reported impact of athletes’ emotions in training settings. In total, 217 athletes completed self-report measures of motivational climate, motivation regulations, emotional states (i.e., pleasant states, anger, and anxiety) experienced before practice at two time points during a 3-month period. Latent change score modeling revealed significantly negative paths from task-involving climate at time 1 to the latent change in the intensity of dysfunctional anxiety and anger, and significantly positive paths from ego-involving climate at time 1 to the latent change in dysfunctional anger (i.e., intens…

Examining Bridge Employment From a Self-employment Perspective : Evidence From the Health and Retirement Study

2017

This study examines bridge employment decision-making from a self-employment perspective using 3 prominent retirement theories, the life course perspective, continuity theory and role theory. Focusing on self-employment extends the current theoretical understanding of bridge employment and offers interesting implications for retirement policy-making. Specifically, using longitudinal data from the Health and Retirement Study (n = 2,080), we conducted multinomial regression analysis to examine who were more/less likely to fully retire, enter bridge employment in the wage-and-salary form, or enter bridge employment in the self-employment form. Furthermore, we examined the role of pre-retiremen…

Skolotāju pašefektivitātes un izdegšanas saistība ar skolotāju un skolēnu attiecībām

2021

Pētījuma mērķis bija noskaidrot, vai starp skolotāju savstarpējām attiecībām ar skolēniem un skolotāju pašefektivitāti pastāv pozitīvas saistības un starp skolotāju skolēnu attiecībām un izdegšanu pastāv negatīvas saistības. Pētījuma datu ievākšanai izmantotas trīs aptaujas: Norvēģu skolotāju pašefektivitātes skala (Norwegian Teacher Self–Efficacy Scale (NTSES), Skaalvik & Skaalvik, 2007; skalu Latvijā adaptējusi G. Virse, 2015), Maslačas Skolotāju izdegšanas aptauja (Maslach Burnout Inventory – Educator’s Survey (MBI-ES), Maslach, Jackson, & Leiter, 1996; Latvijā aptauju adaptēja L.

Predicting Coaches' Adherence/Dropout: A Prospective Study

2015

The objective of this study was to examine motivational variables based on self-determination theory (SDT) and positive psychology as predictors of coaches' adherence and dropout. A prospective study was performed using a sample of 286 coaches who were tracked over a two-year period. Initially coaches' motivation and psychological need satisfaction were measured; two years later they were contacted and asked if they were still coaching in their original sport. Those who did not were considered as drop-outs for the current study. Logistic binary regression analyses were performed to analyse predictors of persistence and dropout. Need Satisfaction Index (NSI), perceived competence and percei…
