This study was designed to check for the equivalence of the ZKPQ-50-CC (Spanish and French versions) through Internet on-line (OL) and paper and pencil (PP) answer format. Differences in means and deviations were significant in some scales, but effect sizes are minimal except for Sociability in the Spanish sample. Alpha reliabilities are also very similar in both versions with no significant differences between formats. A robust factorial structure was found for the two formats and the average congruency coefficients were 0.98. The goodness-of-fit indexes obtained by confirmatory factorial analysis are very similar to those obtained in the ZKPQ-50-CC validation study and they do not differ between the two formats. The multi-group analysis confirms the equivalence among the OL–PP formats in both countries. These results in general support the validity and reliability of the Internet as a method in investigations using the ZKPQ-50-CC.  相似文献

Neuronal inputs from the forebrain and the brainstem to sympathetic preganglionic neurons in the spinal cord were investigated by the transneuronal retrograde tracing technique using pseudorabies virus in intact and brainstem-lesioned rats. After unilateral subcutaneous viral inoculations into the hind limb of intact rats, infected neurons were then visualized by immunostaining. At 3.5 days after inoculation, infected neurons appeared in the thoracic (T10) intermediolateral (IML) cell column. On the 4th day, infected neurons were present in the C1, A5, A6, A7 catecholamine cell groups and the rostral ventromedial medulla (RVMM). On the 5th day, viral labeling was seen in the hypothalamic paraventricular and arcuate nuclei and the lateral hypothalamic area. In all of these nuclei, the infected cells appeared bilaterally. However, the appearance of virus-labeled cells in these nuclei was unilateral following unilateral coronal sections between the medulla and the spinal cord (depending on the side of hemisection, but not on the site of virus inoculation). Midsagittal sections throughout the entire medulla oblongata did not alter the topographical pattern of virus-infected neurons in the forebrain or the brainstem. These findings indicate that descending fibers to the spinal neurons may not cross over in the lower brainstem but that they decussate within the spinal cord.  相似文献

The main concern of the two studies presented here is to investigate whether the different nature of ingroup and outgroup stereotypes is reflected in different selective processing of ingroup and outgroup information. It was predicted that when processing ingroup information people will preferentially encode stereotype-inconsistent information as compared to stereotype-consistent information, whereas the reverse pattern will hold when people process outgroup information. In addition to selective processing, response bias due to stereotyping was studied. To measure selective processing and response bias, recognition memory measures derived from the theory of signal detection were used. Results of the two studies confirmed our main prediction. Also, response bias was demonstrated. ©1997 John Wiley & Sons, Ltd.  相似文献

Although people with intellectual disabilities (ID) are increasingly expected to relocate from traditional institutional care to ‘regular’ neighbourhood housing facilities and socially integrate in these neighbourhoods, little is known about how they are perceived and appreciated as neighbours. This paper reports on interviews carried out with 30 neighbours without ID who were neighbours of small‐scale care facilities for people with ID. Interviews addressed the neighbours' everyday experiences of neighbouring in general, and neighbouring people with ID in particular. Neighbouring, for these informants, called for a fine balance between friendliness without over‐involvement. While they were generally positive about their interactions with their neighbours with ID, it emerged that the formal nature of the care facility and the interaction style of some of the neighbours with ID often contravened informants' assumptions about neighbouring. Informants expressed concern about a possible lack of appropriate distance, reciprocity and accountability among their neighbours with ID. The nature of the care facility, with paid staff, often group activities, formal means of achieving the everyday small tasks which neighbours sometimes do for each other, and a high turnover of residents, all undermined the possibility of a typical neighbourly relationship. In conclusion, we suggest that integration of people with ID into everyday neighbouring relationships raises complex challenges for care organizations that need to find a balance between supporting the needs of people with ID they care for, adequate support and mediation for other neighbours when necessary, and all the while avoid becoming overly involved in neighbouring as a formal partner.

The Precautionary Principle is a guide to coping with scientific uncertainties in the assessment and management of risks. In recent years, it has moved to the forefront of debates in policy and applied ethics, becoming a key normative tool in policy discussions in such diverse areas as medical and scientific research, health and safety regulation, environmental regulation, product development, international trade, and even judicial review. The principle has attracted critics who claim that it is fundamentally incoherent, too vague to guide policy, and makes demands that are logically and scientifically impossible. In this paper we will answer these criticisms by formulating guidelines for its application that ensure its coherence as a useful normative guide in applied and policy ethics debates. We will also provide analyses of cases that demonstrate how our version of the principle functions in practice.  相似文献
