TL;DR: In this paper, the authors argue that management accounting practice in Finland is tied to the national culture surrounding it, i.e., Finnishness and that the Finnish management accounting culture is currently in a significant transition.

TL;DR: It is proposed that regulation of PSII photoinhibition is the ultimate regulator of the photosynthetic electron transfer chain and provides a photoprotection mechanism against formation of reactive oxygen species and photodamage in PSI.

TL;DR: The results suggest that regional abundance variation is a primary factor influencing the composition of local assemblages and implies that maintenance of habitat heterogeneity on a small scale (10n15 m) is needed to preserve biodiversity in managed forests.
Abstract: Heterogeneity in species assemblages of forest-floor arthropods m carabid beetles, ants and spiders m within and between different forest age classes was studied in the southern Finnish taiga. The importance of processes operating on the local scale (within the movement radius of the species) vs on the regional scale (among forest stands) in determining the observed variation was assessed. Four data sets with different spatial resolutions in mesic forests in the same general study area were used. The material consists of 18 283 carabids of 51 species, 48 769 spiders of 212 species, and 126 718 worker ants of 23 species. Analyses of abundance variation and species complementarity among successional stages revealed that in all the three taxa species occurring in the mature forest were prevalent in the younger successional stages as well, constituting more than half of the catch in any age class. A great majority of carabid and spider species were widely distributed across the forest age classes, whereas ants include a higher proportion of species with a narrower amplitude across the succession gradient. Comparisons of similarity between samples at increasing distance from one another on the local scale within forest stands (a few tens of meters to a few hundreds of meters) showed a quite consistent pattern in carabids and spiders: there was more variation between sampling sites in young successional forests than in the mature forest. Furthermore, only in the mature forest a slight, albeit statistically not significant, negative relationship between similarity of samples and distance between sampling sites was detected. In carabids and spiders, comparisons between samples located at a distance of 10n15 m from each other showed considerable heterogeneity, the mean percentage similarity being c. 0.6 (in ants c. 0.8). On the regional scale, systematic variation between young and mature forest stands is a major element increasing the total diversity (species turnover c. 50% in carabids and spiders; compositional similarity c. 0.3n0.4 in carabids, 0.2n0.3 in spiders), but variation within forest stands on a spatial scale of 10n15 meters is another important component in the total heterogeneity. The results suggest that regional abundance variation is a primary factor influencing the composition of local assemblages; a set of hypotheses elaborating this conclusion is formulated. The result implies that maintenance of habitat heterogeneity on a small scale (10n15 m) is needed to preserve biodiversity in managed forests.

TL;DR: Job strain may precipitate clinical depression among employees and future intervention studies should test whether job strain is a modifiable risk factor for depression.
Abstract: BACKGROUND: Adverse psychosocial working environments characterized by job strain (the combination of high demands and low control at work) are associated with an increased risk of depressive symptoms among employees, but evidence on clinically diagnosed depression is scarce. We examined job strain as a risk factor for clinical depression. METHOD: We identified published cohort studies from a systematic literature search in PubMed and PsycNET and obtained 14 cohort studies with unpublished individual-level data from the Individual-Participant-Data Meta-analysis in Working Populations (IPD-Work) Consortium. Summary estimates of the association were obtained using random-effects models. Individual-level data analyses were based on a pre-published study protocol. RESULTS: We included six published studies with a total of 27 461 individuals and 914 incident cases of clinical depression. From unpublished datasets we included 120 221 individuals and 982 first episodes of hospital-treated clinical depression. Job strain was associated with an increased risk of clinical depression in both published [relative risk (RR) = 1.77, 95% confidence interval (CI) 1.47-2.13] and unpublished datasets (RR = 1.27, 95% CI 1.04-1.55). Further individual participant analyses showed a similar association across sociodemographic subgroups and after excluding individuals with baseline somatic disease. The association was unchanged when excluding individuals with baseline depressive symptoms (RR = 1.25, 95% CI 0.94-1.65), but attenuated on adjustment for a continuous depressive symptoms score (RR = 1.03, 95% CI 0.81-1.32). CONCLUSIONS: Job strain may precipitate clinical depression among employees. Future intervention studies should test whether job strain is a modifiable risk factor for depression.

TL;DR: Depression was the factor that was associated most significantly with the experienced quality of life, according to SF‐36, and with physical functioning, only the clinical stage had a more significant association than depression.
Abstract: The objective of this study was to examine the quality of life in patients with Parkinson's disease (PD) in a community-based sample (n = 228 patients) using a Medical Outcomes Study 36-Item Short Form Health Survey (SF-36) as a measure. Associations to the variables age, age at onset, duration, clinical stage (Hoehn and Yahr), depression (Zung), and dementia (MMSE) were studied. Women scored significantly lower on five of the eight dimensions of SF-36. Depression, as measured in this study, was more common among parkinsonian women than men. Depression was the factor that was associated most significantly with the experienced quality of life, according to SF-36. With physical functioning, only the clinical stage had a more significant association than depression. To improve the quality of life in patients with PD, it is necessary to make every effort to recognize and relieve the depression of patients with PD.
