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
Worrying is a key concept in describing the complex relationship between anxiety and cognitive control. On the one hand, cognitive control processes might underlie the specific tendency to engage in worrying (i.e., trait worry), conceptualized as a future-oriented mental problem-solving activity. On the other hand, the general tendency to experience the signs and symptoms of anxiety (i.e., trait anxiety) is suggested to impair cognitive control because worrisome thoughts interfere with task-relevant processing. Based on these opposing tendencies, we predicted that the effect of the two related constructs, trait anxiety and trait worry, might cancel out one another. In statistics, such instances have been termed suppressor situations. In four experiments, we found evidence for such a suppressor situation: When their shared variance was controlled, trait worry was positively whereas trait anxiety was negatively related to performance in a memory task requiring strategic, effortful retrieval. We also showed that these opposing effects are related to temporal context reinstatement. Our results suggest that trait worry and trait anxiety possess unique sources of variance, which differently relate to performance in memory tasks requiring cognitive control. 相似文献
The paper begins with a well-known objection to the idea that reasons for action are provided by desires. The objection holds
that since desires are based on reasons (first premise), which they transmit but to which they cannot add (second premise),
they cannot themselves provide reasons for action. In the paper I investigate an attack that has recently been launched against
the first premise of the argument by David Sobel. Sobel invokes a counterexample: hedonic desires, i.e. the likings and dislikings
of our present conscious states. The aim of the paper is to defend the premise by bringing the alleged counterexample under
its scope. I first point out that reference to hedonic desires as a counterexample presupposes a particular understanding
of pleasure, which we might call desire-based. In response, following Sobel, I draw up two alternative accounts, the phenomenological
and the tracking views of pleasure. Although Sobel raises several objections to both accounts, I argue in detail that the
phenomenological view is not as implausible as he claims it to be, whereas the tracking view, on its best version advocated
by Thomas Scanlon, is an instance of the phenomenological view and is therefore also defensible. 相似文献
According to the Desire-Based Reasons Model reasons for action are provided by desires. Many, however, are critical about
the Model holding an alternative view of practical reason, which is often called valued-based. In this paper I consider one
particular attempt to refute the Model, which advocates of the valued-based view often appeal to: the idea of reason-based
desires. The argument is built up from two premises. The first claims that desires are states that we have reason to have.
The second argues that desires do not add to the stock of reasons the agent has for having them. Together the two theses entail
that desires are based on reasons, which they transmit but to which they cannot add. In the paper I deal with a counterexample
to the second premise: tie-breaking desires. I first distinguish two interesting cases and argue that only the second challenges
the premise. Then I move onto analyze this challenge by focusing on Ruth Chang’s recent employment of it. I show that contrary
to its counterintuitive appearance, the challenge can be sustained. However, I also argue that Chang overlooks the full potential
of one particular response to the challenge: the introduction of higher-order reasons determining the normative significance
of these desires. At the same time, I show that this response has a problem that Chang does not consider. As a result, the
response can only partially disarm the challenge of tie-breaking desires; or not at all, depending on what significance we
attribute to the counterexamples. 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
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.
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
