Cognitive maps present an important theoretical concept and methodological tool for the acquirement of insight into the mental image of the environment. Part of the study, conducted in 1999–2000 on a representative sample of the inhabitants of Slovenia (N = 1291), is presented in this paper, namely the part devoted to the perception of regions. Participants were questioned about different aspects of their image of Slovenia, including their preferences for residence in different parts of Slovenia, partition of the country into regions, travelling patterns, environmental problems and solutions, possibilities of development, etc. Cognitive maps appeared as highly selective, with certain general similarities, but also with individual idiosyncrasies, depending on the place of living and other demographic characteristics. Though respondents were not highly devoted to the formation of regions, a rather clear mental image of them appeared. Main findings are discussed and applicability of the cognitive map for planning purposes are substantiated.  相似文献

We examined the association between adulthood emotionality-activity-sociability temperament scale and preclinical atherosclerosis and, whether this association is mediated by cardiovascular risk factors (low-density lipoprotein cholesterol, systolic blood pressure, diastolic blood pressure and body-mass index (BMI)). The participants were a nationally representative sample of 537 men and 811 women from the Cardiovascular Risk in Young Finns study aged 15-30 years at the baseline in 1992 and aged 24-39 years at the follow-up in 2001. Carotid atherosclerosis was assessed by ultrasound scans of the common carotid artery intima-media thickness (IMT) and brachial flow-mediated dilation (FMD). In men, there was an association between the temperament dimension activity and IMT (β = 0.08, p = 0.036) which was partially mediated by BMI (β decreased from 0.08 to 0.05; p-value of Sobel test = 0.002). However, after correction for multiple comparisons the association between IMT and the temperament dimension activity in men was only of borderline significance. In women, there were no associations between temperament and IMT or FMD. These results suggest that a highly active temperament may contribute to early signs of atherosclerosis in men and that body mass may mediate this association.  相似文献

Objective

The aim of this study was to examine how alcohol intake changes during and after transdiagnostic cognitive behaviour therapy for eating disorders (CBT-E). Additionally, the paper considers the relationship between alcohol consumption, eating disorder diagnosis and current major depressive episode at the time of first assessment.

Method

One hundred and forty nine outpatients with an eating disorder (body mass index over 17.5) were divided into high or low alcohol intake groups (HIG and LIG) according to their intake at pre-treatment assessment. Their alcohol intake and eating disorder psychopathology were examined over the course of treatment and follow-up.

Results

There was no difference between the groups on response of the eating disorder to treatment. The HIG significantly reduced their alcohol intake following treatment whilst the intake of the LIG remained stable over the course of treatment and follow-up. There were no group differences in major depression and overall severity of eating disorder at baseline.

Conclusions

The response to CBT-E was not influenced by baseline level of alcohol use. The mean alcohol intake of the heavy drinking subjects decreased without being specifically addressed by the treatment.  相似文献

We determined the prevailing ethical climate at three different schools of a single university, in order to explore possible differences in the ethical climate related to different research fields: the School of Electrical Engineering, Mechanical Engineering, and Naval Architecture; the School of Humanities and Social Sciences; and the School of Medicine. We used the Ethical Climate Questionnaire to survey the staff (teachers and administration) at the three schools, and used the research integrity and organizational climate (RIOC) survey for early-stage researchers at the three schools. The dominant ethical climate type perceived collectively at the three university schools (response rate 49%, n = 294) was Laws and professional codes, which is associated with the cosmopolitan level of analysis and the ethical construct of principle. Individually, the same climate predominated at the schools for engineering and humanities, but the School of Medicine had the Self-interest ethical climate, which is associated with the individual level of analysis and the egoism ethical construct. In the RIOC survey (response rate 85%; n = 70), early-stage researchers from the three university schools did not differ in their perceptions of the organizational research integrity climate, or in their perceived individual, group or organizational pressures. Our study is the first, to the best of our knowledge, to show differences in perceived ethical climate at a medical school compared to other schools at a university. Further studies are needed to explore the reasons for these differences and how they translate to organizational outcomes, such as job satisfaction, commitment to the institution and dysfunctional behaviour, including research misconduct.

Parceling—using composites of observed variables as indicators for a common factor—strengthens loadings, but reduces the number of indicators. Factor indeterminacy is reduced when there are many observed variables per factor, and when loadings and factor correlations are strong. It is proven that parceling cannot reduce factor indeterminacy. In special cases where the ratio of loading to residual variance is the same for all items included in each parcel, factor indeterminacy is unaffected by parceling. Otherwise, parceling worsens factor indeterminacy. While factor indeterminacy does not affect the parameter estimates, standard errors, or fit indices associated with a factor model, it does create uncertainty, which endangers valid inference.

Observation and analysis of large-scale human motion   总被引:2,自引:0,他引:2  
Many team sports include complex human movement, which can be observed at different levels of detail. Some aspects of the athlete's motion can be studied in detail using commercially available high-speed, high-accuracy biomechanical measurement systems. However, due to their limitations, these devices are not appropriate for studying large-scale motion during a game (for example, the motion of a player running across the entire playing field). We describe an alternative approach to studying such large-scale motion, and present a video-based, computer-aided system, developed specifically for the purpose of acquiring large-scale motion data. The baseline of our approach consists of sacrificing much of the spatial accuracy and temporal resolution of widely used biomechanical measurement systems, to obtain data on human movement that span large areas and long intervals of time. Data can be obtained for each of the observed athletes with reasonable amount of operator work. The system was developed using the recordings of a handball match. Several field tests were performed to assess measurement error, including comparison to one of the widely available biomechanical measurement systems. With the help of the system presented, we could obtain position data for all 14 handball players on a 40 x 20 m large court with RMS error better than 0.6 m, covering 1 h of action. Several results, obtained during the handball match study are presented, in order to highlight the importance of large-scale motion acquisition.  相似文献

The authorship criteria of the International Committee of Medical Journal Editors (ICMJE) are widely accepted in biomedical journals, but many studies in large and prestigious journals show that a considerable proportion of authors do not fulfill these criteria. We investigated authorship contributions in a small medical journal outside the scientific mainstream, to see if poor adherence to authorship criteria is common in biomedical journals. We analyzed statements on research contribution, as checked by the corresponding author, for individual authors of 114 research articles, representing 475 authors, submitted to the Croatian Medical Journal (CMJ) from 1999 to 2000. Only 40% of authors fulfilled the ICMJE authorship criteria. The authors listed first on the by-line were more likely to fulfill the authorship criteria than all other authors on the by-line. The percentage of authors fulfilling the ICMJE criteria of authorship decreased with the increase in the number of authors listed on the by-line. These results indicate that poor adherence to ICMJE authorship criteria is poor across biomedical journals, regardless of the size of the scientific community. Authorship and contributorship in biomedical journals, as well as editorial ethical responsibilities towards authorship criteria need critical redefinition and education of both editors and authors.  相似文献

We studied health-related selection and consequences of an organizational downsizing among 886 municipal employees. Measurements of health indicators were conducted before any rumor of the downsizing and immediately after the downsizing 3 years later. Results of predownsizing health showed that those who did not find employment after the staff reductions were older employees with high preexisting morbidity. Those getting a new job elsewhere were younger and had better health already before the downsizing than the stayers. After the downsizing, deterioration of health was most likely in the stayers working in groups of major staff reductions and among the nonemployed leavers. In the reemployed leavers, the risk of increased health problems was lower than in others including employees working in no or minor downsizing groups.  相似文献

Pseudo MV-algebras are a non-commutative extension of MV-algebras introduced recently by Georgescu and Iorgulescu. We introduce states (finitely additive probability measures) on pseudo MV-algebras. We show that extremal states correspond to normal maximal ideals. We give an example in that, in contrast to classical MV-algebras introduced by Chang, states can fail on pseudo MV-algebras. We prove that representable and normal-valued pseudo MV-algebras admit at least one state.  相似文献
