Do social comparison and coping styles play a role in the development of burnout? Cross-sectional and longitudinal findings
2006
The present longitudinal research among 558 teachers focused on the role of upward comparisons (with others performing better), downward comparisons (with others performing worse), and coping styles in relation to burnout. Assessed were identification (recognizing oneself in the other) and contrast (seeing the other as a competitor) in upward and downward comparison. Cross-sectionally, downward identification and upward contrast were positively related to burnout and negatively related to a direct coping style, whereas upward identification was negatively related to burnout and positively related to a direct coping style. Downward identification was positively related to a palliative coping…
The Role of Information and Communication Technologies in the Relationship Between Group Effectiveness and Group Potency
2008
The aim of this research is to examine the role of information and communication technologies in the relationship between group effectiveness and group potency changes. A laboratory experiment compared 44 groups of four members, working in two communication media—face-to-face condition and computer-mediated communication (CMC). Groups developed a project during 4 weekly meetings during a 1-month period. No significant difference in group potency between communication media was found initially. However, different patterns of group potency development over time were identified. Group potency increased in the face-to-face condition, whereas it remained stable in the CMC condition. Results sho…
Effects of record linkage errors on registry-based follow-up studies
1997
The importance of reliable record linkage for high quality-population-based disease registration is widely recognized. Systematic methodologic work is lacking, however, on the effects of record linkage errors on the use of disease registries for epidemiologic purposes. The present paper provides algebraic models describing the effects of record linkage errors on monitoring survival of registered patients, which is commonly performed by matching registry records against a database of death certificates, and on registry-based incidence follow-up of external cohorts. Homonym errors, that is, erroneous linkage of records that pertain to distinct individuals, lead to underestimation of survival …
Team climate, climate strength and team performance: a longitudinal study
2009
We tested the hypothesis that the relationship between team climate and team performance is moderated by climate strength. The study sample was composed of 155 bank branches, and a two-wave panel design was implemented. We measured four team climate facets (support, innovation, goal achievement and enabling formalization). We obtained two subjective indicators of team performance (ratings provided by team members and by team managers) and a financial indicator of team performance. Seven out of the 12 interaction effects tested were statistically significant and showed the expected sign. When financial team performance was the criterion, only the interaction term was significant. This sugges…
Relations between enabling skills and reading comprehension: a follow-up study of Latvian students from first to second grade.
2004
Sprugevica, I. & Hoien, T. (2004). Relations between enabling skills and reading comprehension: A follow-up study of Latvian students from first to second grade. Scandinavian Journal of Psychology, 45, 115–122. In order to examine the relationships among various phonological skills and reading comprehension, Latvian children were followed from grade 1 to grade 2 and were tested with a battery of phonological, word reading, and reading comprehension tasks. A principal component analysis of the phonological tasks revealed three salient factors: a phonemic awareness factor, a rapid naming factor, and a short-term memory factor. In order to analyze the relationship between various phonological …
Parents' Physical Activity, Socioeconomic Status and Education as Predictors of Physical Activity and Sport among Children and Youths - A 12-Year Fol…
1996
The purpose of this study was to examine parental influences on children's participation in sport and their later physical activity. The population for the study consisted of a random sample of 1881 9- to 15-year-old boys and girls who were exposed to the extensive research program called "Cardiovascular Risk in Young Finns" in 1980. They and their parents have been followed up for twelve years at three-year intervals by means of a short questionnaire concerning physical activity and other factors. The results indicated that the fathers' physical activity in 1980 was related to their children's habitual physical activity in the same year, and gave in boys and girls a significant prediction…
Distortion product otoacoustic emissions in healthy newborns: normative data.
1995
Distortion product otoacoustic emissions (DPOAE) offer an alternative to transiently evoked otoacoustic emissions (TEOAE) as an audiological test. The former can be used as a screening technique, and may also provide frequency-specific information about the functional state of the cochlea. We recorded DPOAE in a group of healthy newborns to establish the Characteristics of a DPOAE “audiogram” (DP-gram) in this population. The DP-gram can be obtained with characteristics quite similar to those observed in adults, with two sharp peaks of maximum amplitude at F2 frequencies of 2 kHz and 5-6 kHz, and a decline in DPOAE amplitude in mid frequencies. The results confirm the limitations of DPOAE r…
Extremely low-frequency magnetic fields and survival from childhood acute lymphoblastic leukemia: an international follow-up study
2012
A previous US study reported poorer survival in children with acute lymphoblastic leukemia (ALL) exposed to extremely low-frequency magnetic fields (ELF–MF) above 0.3 μT, but based on small numbers. Data from 3073 cases of childhood ALL were pooled from prospective studies conducted in Canada, Denmark, Germany, Japan, UK and US to determine death or relapse up to 10 years from diagnosis. Adjusting for known prognostic factors, we calculated hazard ratios (HRs) and 95% confidence intervals (CI) for overall survival and event-free survival for ELF–MF exposure categories and by 0.1 μT increases. The HRs by 0.1 μT increases were 1.00 (CI, 0.93–1.07) for event-free survival analysis and 1.04 (CI…
Effects of Individual Changes in Training Distribution on Maximal Aerobic Capacity in Well-Trained Cross-Country Skiers: A Follow-Up Study
2021
The purpose of this study was to evaluate individual changes in training distribution and the subsequent effects on maximal oxygen uptake (VO2max). The participants were well-trained cross-country skiers who had performed a year with no substantial changes in training prior to this study. Six cross-country skiers, who were participants in a larger previous study, volunteered for a follow-up study. All skiers performed self-motivated changes in training distribution for a new preparation period in this follow-up, generally by more high-intensity training (HIT). All training characteristics were registered from training diaries. During the follow-up period, all skiers performed an incremental…
