Bad but bold: Ambivalent attitudes toward men predict gender inequality in 16 nations

A 16-nation study involving 8,360 participants revealed that hostile and benevolent attitudes toward men, assessed by the Ambivalence Toward Men Inventory (P. Glick & S. T. Fiske, 1999), were (a) reliably measured across cultures, (b) positively correlated (for men and women, within samples and across nations) with each other and with hostile and benevolent sexism toward women (Ambivalent Sexism Inventory, P. Glick & S. T. Fiske, 1996), and (c) negatively correlated with gender equality in cross-national comparisons. Stereotype measures indicated that men were viewed as having less positively valenced but more powerful traits than women. The authors argue that hostile as well as benevolent attitudes toward men reflect and support gender inequality by characterizing men as being designed for dominance.

Demographic category membership and leadership in small groups: A social identity analysis

Developing the social identity theory of leadership (e.g., [Hogg, M. A. (2001). A social identity theory of leadership. Personality and Social Psychology Review, 5, 184-200]), an experiment (N=257) tested the hypothesis that as group members identify more strongly with their group (salience) their evaluations of leadership effectiveness become more strongly influenced by the extent to which their demographic stereotype-based impressions of their leader match the norm of the group (prototypicality). Participants, with more or less traditional gender attitudes (orientation), were members, under high or low group salience conditions (salience), of non-interactive laboratory groups that had instrumental or expressive group norms (norm), and a male or female leader (leader gender). As predicted, these four variables interacted significantly to affect perceptions of leadership effectiveness. Reconfiguration of the eight conditions formed by orientation, norm and leader gender produced a single prototypicality variable. Irrespective of participant gender, prototypical leaders were considered more effective in high then low salience groups, and in high salience groups prototypical leaders were more effective than less prototypical leaders. Alternative explanations based on status characteristics and role incongruity theory do not account well for the findings. Implications of these results for the glass ceiling effect and for a wider social identity analysis of the impact of demographic group membership on leadership in small groups are discussed.

Perceptions of stranger and acquaintance rape: The role of benevolent and hostile sexism in victim blame and rape proclivity

In Studies I and 21 after reading an acquaintance-rape but not a stranger-rape scenario, higher benevolent. sexist but not hostile sexist participants blamed the victim significantly more. In Study 2, higher hostile sexist but not benevolent sexist male participants showed significantly greater proclivity to commit acquaintance (but not stranger) rape. Studies 3 a effects of nd 4 'slippor,ted the hypothesis that the benevolent sexism and hostile sexism are mediated by different perceptions of the victim, as behaving. inappropriately and as really wanting sex with the rapist. These findings show that benevolent sexism and hostile sexism,underpin different assumptions about women that, generate sexist reactions toward rape victims.

Reinforcing the glass ceiling: The consequences of hostile sexism for female managerial candidates

Previous research has established that benevolent sexism is related to the negative evaluation of women who violate specific norms for behavior. Research has yet to document the causal impact of hostile sexism on evaluations of individual targets. Correlational evidence and ambivalent sexism theory led us to predict that hostile sexism would be associated with negative evaluations of a female candidate for a masculine-typed occupational role. Participants completed the ASI (P. Glick & S. T. Fiske, 1996) and evaluated a curriculum vitae from either a male or female candidate. Higher hostile sexism was significantly associated with more negative evaluations of the female candidate and with lower recommendations that she be employed as a manager. Conversely, higher hostile sexism was significantly associated with higher recommendations that a male candidate should be employed as a manager. Benevolent sexism was unrelated to evaluations and recommendations in this context. The findings support the hypothesis that hostile, but not benevolent, sexism results in negativity toward individual women who pose a threat to men's status in the workplace.

Hostile sexism and rape proclivity amongst men

In the current study, we examined the influence of victim type and hostile sexism on men's judgments about an acquaintance rape victim and their self-reported acquaintance rape proclivity. It was predicted that hostile sexism would predict self-reported rape proclivity, but that this relationship would be moderated by victim type. Specifically, it was predicted that participants would report greater proclivity in relation to a victim who appeared not to adhere to traditional gender stereotypes than to a victim who appeared to adhere to such stereotypes. Further, in line with D. Abrams, G. T. Viki, B. Masser, and G. Bohner (2003), it was predicted that the relationship between hostile sexism and rape proclivity would be mediated by perceptions of token resistance by the victim. Results partially supported the hypotheses. Hostile sexism was positively related to rape proclivity, but victim type was not found to moderate the relationship. In addition, perceptions of token resistance were found to mediate the hostile sexism and rape proclivity relationship. The results suggest that, at least in terms of rape proclivity, hostile sexists may not differentiate in their targets for sexual aggression.

Adenocarcinoma of colon differentiating as dome epithelium of gut-associated lymphoid tissue

Aims: An early adenocarcinoma of the ascending colon was confined to a mass of gut-associated lymphoid tissue (GALT). The first description of an adenocarcinoma of colon differentiating as dome epithelium is presented. Methods and results: A plaque-like carcinoma was identified opposite the ileocaecal valve in an asymptomatic 56-year-old man with a family history of colorectal cancer. Malignant epithelium was confined to a mass of GALT filling but limited to the submucosa, Characterization of the neoplasm was undertaken by means of mucin histochemistry, immunohistochemistry, electron microscopy and assessment of DNA microsatellite instability status. The malignant epithelium comprised well differentiated columnar cells with a microvillous brush border and expressing MUC1, but no goblet cells or expression of MUC2. The demonstration of focal clusters of intraepithelial B-lymphocytes supported the presence of functioning M-cells within the malignant neoplasm. The cancer was DNA microsatellite stable despite the finding of tumour infiltrating lymphocytes. Conclusions: There is evidence for the origin of colorectal neoplasia from dome epithelium in both experimental models and microreconstruction studies of early adenomas in nonpolypotic human colorectal mucose, It is suggested that the lymphocyte-rich subset of colorectal cancer that expresses MUC1 but not MUC2 may be differentiating as dome epithelium of gut-associated lymphoid tissue.

Differentiating responses to obstructive sleep apnoea using pulse transit time

Conventional overnight polysomnography (PSG) used to determine the respiratory behaviour during sleep can be a complex and expensive procedure. Pulse transit time analysis (PTT) has shown potential to detect obstructive apnoeic and hypopnoeic events in adults. This study was undertaken to determine the potential of PTT to differentiate responses to upper airway obstruction. 103 obstructive respiratory events occurred in PSG studies performed on 11 children (10 male and 1 female, mean age 7.5years). PTT measurements were evaluated against the corresponding PSG results pre-scored by 2 blinded observers. Broadly, there were 2 types of responses. They can be either short period of rapid PTT decreases (Type 1) or prolonged but gradual PTT decreases (Type 2). Type 1 obstructive events showed a mean change of 51.77% (p
