Development of depressive tendencies was assessed over a 9-year period in a random sample of 389 Finnish children. Predictors of maternal role satisfaction and hostile child-rearing attitudes, assessed when the children were ages 6 and 9 years, respectively, and a temperament predictor of perceived child difficultness, assessed when the children were age 6 years, were measured using questionnaires designed for this study. Depressive tendencies were assessed by a self-report at age 15 (modification of Beck's Depression Inventory). Using structural equation modeling, we tested a hypothesized model comprising direct as well as mediated effects between the childhood predictor variables and adolescent depressive tendencies. The results indicated support for a similar mediational model in girls and boys. Low maternal role satisfaction and maternal perceptions of child difficultness, measured when children were age 6 years, predicted hostile maternal child-rearing attitudes measured when children were age 9 years, which in turn had a significant direct effect on depressive tendencies among these children during adolescence. The only other direct effect was found solely in girls: Low maternal role satisfaction predicted adolescent depressive tendencies. These results underline the close interplay of child temperament and mothering factors in the development of depressive tendencies in girls and boys. 相似文献

The authors describe 3 cases where Y-chromosomal systems were used for typing the biological traces. In the first case, a murder, for the major amount of cell material found on a dish towel (and analysed two years after the crime) female persons were excluded for the system amelogenin and Y-chromosomal systems. A brother of the victim could not be excluded for autosomal STR-systems. Upon confrontation with the results of the DNA-analysis (among other things), this brother confessed the murder of his sister some days later. He was found guilty by the court. In the second case described, a rape of two girls, many traces were analysed parallely with Y-chromosomal and autosomal PCR-systems. The objects where male DNA matching the suspect were found (a paper tissue, a sweat shirt and the knickers of the girls), also showed small amounts of alleles matching with the suspect for autosomal systems, while the major part in these systems was from the girls. The suspect was sentenced to many years imprisonment. In the third case, a possible rape of a young woman, a stained microscope slide of a vaginal swab had to be examined. Microscopically a few sperm heads could be seen in a surplus of leucocytes. The male proportion could be analysed only in the Y-chromosomal systems, not in the autosomal ones. For the frequency calculation of the Y-chromosomal allele combination the haplotype data bank of the Institute for Legal Medicine of the Humboldt university in Berlin was indispensable. 相似文献

Seit dem 7. 9. 2004 liegt ein weiteres Urteil des EuGH zum europäischen Abfallbegriff vor. Danach ist Benzin, das unbeabsichtigt in den Boden und das Grundwasser gelangt, ebenso als Abfall zu qualifizieren wie das verunreinigte Erdreich selbst. Nach Ansicht des Gerichtshofs spielt es dabei keine Rolle, ob der Boden nach der Verschmutzung ausgehoben worden ist oder nicht. Diese Rechtsprechung steht nicht länger im Einklang mit der ständigen Rechtsprechung deutscher Gerichte und wirft insbesondere mit Blick auf die fehlende Sonderrechtsfähigkeit nicht ausgehobenen kontaminierten Erdreichs Fragen auf, denen im folgenden Beitrag nachgegangen werden soll. 相似文献

Purpose. In police interviews children may be asked the same question many times. We investigated how the number of repetitions and the interval between those repetitions affected the accuracy and consistency of children's responses. Methods. 156 children aged 4–9 years watched a staged event and were interviewed individually 1 week later. Children were asked eight open‐ended questions, which were each repeated a further four times (making a total of forty questions). Half these open‐ended questions could be answered from information in the event, and half were unanswerable (so children should have said ‘don't know’ in response to these questions). The questions were repeated in gist form. The interval between an initial question and its repetitions was varied by use of other questions and twenty non‐repeated filler questions. The intervals between repetitions were immediate repetition, repetition after a delay of three intervening questions, after a delay of six intervening questions, and after ten or more intervening questions. Results. Over a quarter of children's responses to repeated questions changed, usually resulting in a decline in accuracy, particularly after the first repetition. Subsequently, the number of repetitions and delay interval had little effect on responses to answerable questions although accuracy to unanswerable questions continued to decline. Conclusions. Question repetition had a negative affect on children's consistency and accuracy. For unanswerable questions in particular, the more often a question was repeated the more likely children were to invent a response. 相似文献

Public-goods dilemmas are characterized by conflicts between self-interest and the welfare of a group or society at large. Research has identified several factors that enhance cooperation in such dilemmas. However, less is known about how concern for distributive justice affects willingness to contribute in asymmetric public-goods dilemmas. To test the hypothesis that contributions to a common resource is related to perceived fairness, experiments were performed to investigate willingness to pay to the social service of child care in hypothetical societies. Experiment 1 aimed at replicating a previous survey study (Biel et al., 1997). Experiments 2 and 3 were extensions. In all three experiments subjects were asked to indicate how fair they considered different distributions of the quality of child care provided by their municipality. These distributions corresponded to the principles of equality, equity, and need. University students (32, 48, and 32 in the three experiments, respectively) served as subjects. Ratings of perceived fairness were positively related to willingness to pay. Other factors also positively related to willingness to pay included ability to pay, personal need, expected payment from others, and the number of households who had to contribute in order to maintain the quality. Furthermore, decreasing municipality size increased willingness to pay. 相似文献

Accountability processes after crisis events sometimes entail harsh criticism from public and political players alike, forcing cabinet ministers to be on top of the political game and sometimes even resign. However, harsh accountability processes are just as likely to leave ministers undamaged. This article combines two existing theories that propose different factors to account for variation in outcomes: ministerial resignations as a consequence of cabinet formation and individual positions; or resignations as a result of blame management strategies involving individual actors within the cabinet and beyond. Ten crisis episodes in Sweden are analysed and compared. The findings suggest that individual political power bases and experience matter to how well blame management strategies can be employed, while the composition of the government gives structural constraints. The dynamic interplay and framing battle between incumbent decision makers, and external arenas and the skill with which individual ministers engage and frame responsibility, play a key role in determining their post‐crisis careers. 相似文献
