In studies related to human movement, linked segment models (LSM's) are often used to quantify forces and torques, generated in body joints. Some LSM's represent only a few body segments. Others, for instance used in studies on the control of whole body movements, include all body segments. As a consequence of the complexity of 3-dimensional (3-D) analyses, most LSM's are restricted to one plane of motion. However, in asymmetric movements this may result in a loss of relevant information. The aim of the current study was to develop and validate a 3-D LSM including all body segments. Braces with markers, attached to all body segments, were used to record the body movements. The validation of the model was accomplished by comparing the measured with the estimated ground reaction force and by comparing the torques at the lumbo-sacral joint that resulted from a bottom-up and a top-down mechanical analysis. For both comparisons, reasonable to good agreement was found. Sources of error that could not be analysed this way, were subjected to an additional sensitivity analysis. It was concluded that the internal validity of the current model is quite satisfactory. 相似文献

This study tested predictions concerning the associations between children's nonparental care experiences and emotion regulation. It involved 53 participants (21 girls and 32 boys) of preschool age and their mothers. The children's care experiences ranged from those who were raised exclusively at home to those who had nonparental care experience beginning in early infancy. The participants were observed in a laboratory playroom, and their mothers were asked to complete questionnaires regarding their children's care histories and their current care situations. The children with extensive nonparental care backgrounds were found to be more likely to use self-directed emotion regulation behaviors when faced with a mildly frustrating situation. In the same situation, the children who had experienced minimal nonparental care were found to be more likely to use other-directed emotion regulation behaviors. Additionally, the children who had experienced care settings with large numbers of children in each care group or who had experienced many caregiver changes were more likely to use self-directed emotion regulation behaviors, whereas those who had experienced settings with smaller care groups and fewer caregiver changes were more likely to use other-directed emotion regulation behaviors. 相似文献

In a series of three experiments, subjects made risky decisions under conditions of hypothetical or real consequences. Task variations across experiments included: (1) type of risk (monetary gambles or investments of time and effort), (2) within-subject and between-subjects manipulations of consequence condition, and (3) single or multiple decisions. The hypothesis of no difference between choices in real and hypothetical consequence conditions was retained in each experiment. Supplemental analyses ruled out various “artifactual” interpretations of the null results. Discussion focused on conditions in which researchers can and cannot infer decision makers’ actual risk preferences from their responses in laboratory tasks. 相似文献

Develops two validity scales for the Jesness Inventory using a rational approach: a fake-good scale, Lie (L); and a fake-bad scale, Overt Symptomatology (OS). Effectiveness was assessed using 293 male delinquents classified as fake-good, fake-bad, or honest based on a matched-pair MMPI-A. L was moderately effective in detecting the fake-good set, and OS tentatively effective in detecting the fake-bad set. Both correlated well with their MMPI-A counterparts. Sensitivity, specificity, positive predictive power, negative predictive power, and overall effectiveness data were reported. The L scale and OS scale were related to race but differences were less than 1 raw score point. L was unrelated to age. OS was related to age, with younger children showing more willingness to admit to symptomatology. Age-based modified T-score norms were developed for the newly constructed scales using 1142 male and 360 female delinquents. ages 13–18. 相似文献

No one factor could have as great an impact on multinational corporations (MNCs) than the dual-career phenomena. The selection of expatriate candidates is a complex process made more arduous by the career orientation of the expatriate's spouse. The need for a social support network is essential for the dual-career family to increase the probability of successfully completing an expatriate assignment. 相似文献

Previous studies have shown that the Common Beliefs Survey III (CBS III) is an irrational beliefs inventory with satisfactory psychometric properties. We extended research on the CBS by examining this 54-item inventory for redundant material, and substantially abbreviated it without compormising its reliability or validity. This article describes the development of the new, 19-item short form (CBS19), convenient for clinical use, that preserves the psychometric properties of the original. 相似文献

Zusammenfassung
Chronisch-entzündliche Darmerkrankungen (Morbus Crohn, Colitis ulcerosa) werden traditionellerweise zu den psychosomatischen
Erkrankungen gez?hlt. In jüngster Zeit wurde diese Zuordnung aber mehrfach in Frage gestellt; zugleich wurden biomedizinische
Faktoren beschrieben, die in der Entstehung und im Verlauf der Erkrankungen eine Rolle spielen k?nnten. Die vorliegende übersichtsarbeit
hat das Ziel, den aktuellen Stand der biomedizinischen und psychosomatischen Forschung zur ?tiologie und Verlaufsgestaltung
bei chronisch-entzündlichen Darmerkrankungen darzustellen und unter methodischen Gesichtspunkten kritisch zu bewerten. Forschungsergebnisse
zu folgenden Themenbereichen werden referiert: Epidemiologie; soziodemographische Merkmale; Genetik; di?tetische Faktoren
und Zigarettenrauchen; Medikamente; Permeabilit?tsst?rung der Darmepithelien; immunologische Faktoren; mikrobiologische Faktoren;
psychiatrische St?rung; emotionale Symptomatik, Pers?nlichkeitsmerkmale; kritische Lebensereignisse und psychosozialer Stre?;
Lebensqualit?t und Krankheitsbew?ltigung.

Premise acceptability is conceptually connected to presumption. To say that a premise is acceptable just when there is a presumption in its favor is to give a first approximation to this connection. A number of popular principles of presumption suggest that whether there is a presumption for a premise, belief, or claim depends on the sources which vouch for it. Sources consist of internal belief-generating mechanisms and external testimony. Alvin Plantinga's notion of warrant lays down four conditions upon a source for the belief which it generates to be warranted. We argue that there is a presumption for a premise, belief, or claim if and only if there is a presumption of warrant for that premise,belief or claim. This amounts to the thesis that there is a presumption for a belief from a challenger's point of view if and only if there is a presumption from that person's point of view that her cognitive faculties which have generated the belief have been functioning properly, in an appropriate cognitive environment, in accord with a segment of her design plan aimed at the truth, and that these faculties are reliable. In light of our argument for this thesis, we may legitimately claim that one way to determine that there is a presumption for a belief is to determine that there is a presumption of warrant for that belief, and thus that in determining whether there is a presumption for a belief or premise, we may consider the source. 相似文献
