Sex-role typing as related to acceptance of self, acceptance of others, and discriminatory attitudes toward women

This study examines four hypotheses relating sex-role typing to self-acceptance, acceptance of others, and sexist attitudes toward women. University students completed the Bem Sex-Role Inventory, the Berger Self-Acceptance Scale, and the Macho Scale. Findings showed more self-acceptance than acceptance of others among masculine-typed subjects and more acceptance of others than self-acceptance among feminine-typed subjects. Feminine-typed males and masculine-type females showed least self-acceptance among the six groups, while androgynous subjects showed highest self-acceptance. Masculine-typed males were least accepting of others and scored highest in discriminatory attitudes toward women. Male subjects showed greater variability than did female subjects on all scales, and Bem's measure of sex-role typing proved a more efficient moderator of scores of males than of those of females. Additional personality and behavioral research with sex-role typing variables is proposed.     

Estimating the parameters of the latent population distribution

Under consideration is a test battery of binary items. The responses ofn individuals are assumed to follow a Rasch model. It is further assumed that the latent individual parameters are distributed within a given population in accordance with a normal distribution. Methods are then considered for estimating the mean and variance of this latent population distribution. Also considered are methods for checking whether a normal population distribution fits the data. The developed methods are applied to data from an achievement test and from an attitude test.     

Detection of three-dimensional surfaces from optic flow: The effects of noise

Previous research (Andersen, 1989) has suggested that the recovery of 3-D shape from nonsmooth optic flow (motion transparency) can be performed by segregating surfaces according to the distributions of velocities present in the flow field. Five experiments were conducted to examine this hypothesis in a surface detection paradigm and to determine the limitations of human observers to detect 3-D surfaces in the presence of noise. Two display types were examined: a flow field that simulateda surface corrugated in depth and a flow field-that simulated a random volume. In addition, two types of noise were examined: a distribution of noise velocities that overlapped or did not overlap the velocity distribution that defined the -surface. Corrugation frequency and surface density were also examined. Detection performance increased with decreasing corrugation frequency, decreasing noise density, and decreasing surface density. Overall, the subjects demonstrated remarkable tolerance to the presence of noise and, for some conditions, could discriminate surface from random conditions when noise density was twice the-surface density. Discrimination accuracy was greater for the nonoverlapping than for the overlapping noise, providing support for an analysis based on the distribution of velocities.     

Interaction between theory and practice in the surgical treatment of ulcer disease in the period of 1880–1920

Newly developed techniques for anaesthesia and asepsis made it possible for surgeons to attempt operative attacks on diseases which had been previously incurable. The period around the turn of the century is sometimes portrayed as one of very active development of new surgical methods. This activity has been seen as a result of fertile scientific thinking. It is demonstrated in the paper that it was in fact a barren period with a prolonged adherence to an anatomical concept as the basis for problem solving. It is described in terms of Kuhnian periods of normal activity and crisis. It took about fifty years before theory and practice were harmonized under a physiological concept and real progress was made.     

Use of temperature variations to combat drivers' drowsiness

The purpose of the present study was to evaluate the efficiency of temperature variations as a measure against drivers' drowsiness. A system for regulation of the air temperature in the cab was installed in two trucks. Irregular temperature reductions of about 8 degrees C were introduced. The periods between the temperature reductions varied among 5, 6, 7, and 8 min. The periods for the temperature reductions varied between 2, 4, 6, and 8 min. The system was tested with 6 drivers on 54 trips. The system was applied for periods varying between 30 to 300 min. Changes in wakefulness were analysed using subjective ratings by the lorry drivers. The application of the system significantly improved subjectively rated wakefulness. The wakefulness was rated with a questionnaire completed after 10 min. use of a cooling system and at the end of its use. Analysis showed individual differences in the usefulness of the system: 3 of the 6 truck drivers reported positive reactions to the use of the temperature cooling system.     

Perceived internal depth in rotating and translating objects

Previous research has indicated that observers use differences between velocities and ratios of velocities to judge the depth within a moving object, although depth cannot in general be determined from these quantities. In four experiments we examined the relative effects of velocity difference and velocity ratio on judged depth within a transparent object that was rotating about a vertical axis and translating horizontally, examined the effects of the velocity difference for pure rotations and pure translations, and examined the effect of the velocity difference for objects that varied in simulated internal depth. Both the velocity difference and the velocity ratio affected judged depth, with difference having the larger effect. The effect of velocity difference was greater for pure rotations than for pure translations. Simulated depth did not affect judged depth unless there was a corresponding change in the projected width of the object. Observers appear to use the velocity difference, the velocity ratio, and the projected width of the object heuristically to judge internal object depth, rather than using image information from which relative depth could potentially be recovered.     

Theological Ethics, Moral Philosophy, and Natural Law

The article deals with the relationship between theological ethics and moral philosophy. The former is seen as a theoretical reflection on Christian ethics, the latter as one on secular ethics. The main questions asked are: (1) Is there one and only one pre-theoretical knowledge about acting rightly? (2) Does philosophy provide us with the theoretical framework for understanding both Christian and secular ethics? Both questions are answered in the negative. In the course of argument, four positions are presented: theological ‘unificationism’, philosophical ‘unificationism’, theological ‘separationism’ and Lutheran ‘dualism’. It is argued that the latter position is most convincing. It is dual in the sense of being both a theory of Christian ethics and of including a recognition of natural law. Hence, it unites a particularistic and a universalistic point of view. In the last section a reformulation of the Lutheran position is attempted in making use of the ethical theory of Knud E. Løgstrup's The Ethical Demand.     

Relational to collective: significant-other representations, ethnic categories, and intergroup perceptions

Social perception is known to be affected by the social-cognitive process of transference-that is, by a new person bearing a minimal resemblance to a significant other, which activates the significant-other representation and indirectly the relational self. We examined relational processes in social identity and intergroup bias in two studies testing the dual hypothesis-that activating a significant-other representation in transference activates the significant other's ethnic category, which is then applied to the new person, and that under this circumstance the participant's own ethnic identity should also be activated as the relational self is activated, particularly if the participant shares the significant other's ethnicity. This should lead to shifts in intergroup bias as moderated by the ethnic diversity of the significant other's own social network. The evidence largely supports this, revealing the interplay of relational and collective levels of self.     

Comparing Quality of Life Instruments in a Population of Abused Women

The SF-36 Health Survey and the WHO Quality of Life Index—BREF (WHOQOL-BREF) were used to study quality of life among women who had experienced intimate partner violence (IPV). The aim was to determine how these instruments correlated with each other and with physical and psychological IPV, in order to find the best instrument to use. IPV was measured using the Severity of Violence against Women Scale (SVAWS) and the Psychological Maltreatment of Women Index (PMWI). A self-administrated questionnaire was given to women able to understand Norwegian who were staying at a women’s shelter in Norway for more than 1 week. 87 of 212 women asked to participate completed the questionnaire. The physical acts of violence in SVAWS correlated significantly (P<0.001) with both the general health and bodily pain dimensions in SF-36 and global overall health (OH) in WHOQOL-BREF. Most correlations between WHOQOL-BREF and SF-36 were moderate. The WHOQOL-BREF domains explained 46% of the variance in OH and 40% of the variance in the global overall quality of life (OQOL). The SF-36 domains explained 66% of the variance in OH and 27% of OQOL. The mean WHOQOL-BREF and SF-36 scores were all low. The SF-36 correlated better with physical and psychological IPV in this population than the WHOQOL-BREF. The significant correlations between the OH, general health and bodily pain domains and acts of violence show the importance of including questions concerning bodily symptoms in determining the quality of life in a population of abused women.
