Communality sells: The impact of perceivers' sexism on the evaluation of women's portrayals in advertisements

Portrayals of women in advertisements have a significant impact on the maintenance of gender stereotypes in society. Therefore, the present research investigates the effectiveness of communal and agentic female characters in advertisements as well as the question how evaluations of such characters are influenced by perceivers' sexist attitudes toward women. Results show that communal female advertising characters are evaluated more favorably than agentic ones and that these evaluations predict advertising effectiveness. Benevolent sexism predicts more positive evaluations of communal female advertising characters (studies 1 and 2). Moreover, hostile sexism predicts less positive evaluations of agentic female advertising characters when it is assessed under time pressure (Study 2). Implications of these findings for the perpetuation of gender stereotypes in advertisements and in society are discussed.

Effects of thoracic epidural analgesia on lower urinary tract function in women

The need for an indwelling transurethral catheter in patients with postoperative thoracic epidural analgesia (TEA) is a matter of controversy. Subjective observations are ambivalent and the literature addressing this issue is scarce. As segmental blockade can be achieved with epidural analgesia, we hypothesized that analgesia within segments T4-T11 has no or minimal influence on lower urinary tract function. Thus, we evaluated the effect of TEA on lower urinary tract function by urodynamic studies.

Cause or effect of arteriogenesis: compositional alterations of microparticles from CAD patients undergoing external counterpulsation therapy

Recently, a clinical study on patients with stable coronary artery disease (CAD) showed that external counterpulsation therapy (ECP) at high (300 mmHg) but not at low inflation pressure (80 mmHg) promoted coronary collateral growth, most likely due to shear stress-induced arteriogenesis. The exact molecular mechanisms behind shear stress-induced arteriogenesis are still obscure. We therefore characterized plasma levels of circulating microparticles (MPs) from these CAD patients because of their ambivalent nature as a known cardiovascular risk factor and as a promoter of neovascularization in the case of platelet-derived MPs. MPs positive for Annexin V and CD31CD41 were increased, albeit statistically significant (P<0.05, vs. baseline) only in patients receiving high inflation pressure ECP as determined by flow cytometry. MPs positive for CD62E, CD146, and CD14 were unaffected. In high, but not in low, inflation pressure treatment, change of CD31CD41 was inversely correlated to the change in collateral flow index (CFI), a measure for collateral growth. MPs from the high inflation pressure group had a more sustained pro-angiogenic effect than the ones from the low inflation pressure group, with the exception of one patient showing also an increased CFI after treatment. A total of 1005 proteins were identified by a label-free proteomics approach from MPs of three patients of each group applying stringent acceptance criteria. Based on semi-quantitative protein abundance measurements, MPs after ECP therapy contained more cellular proteins and increased CD31, corroborating the increase in MPs. Furthermore, we show that MP-associated factors of the innate immune system were decreased, many membrane-associated signaling proteins, and the known arteriogenesis stimulating protein transforming growth factor beta-1 were increased after ECP therapy. In conclusion, our data show that ECP therapy increases platelet-derived MPs in patients with CAD and that the change in protein cargo of MPs is likely in favor of a pro angiogenic/arteriogenic property.

Vom Sonderfall zur Integration? Das Verhältnis zwischen grundständigem und weiterbildendem Studium

Vom Sonderfall zur Integration? Das Verhältnis der universitären Weiterbildung zu Lehre und Forschung ihrer Mutterinstitutionen ist ambivalent. Die Weiterbildung wird in der Universität von vielen geschätzt, aber dabei kaum als Kernaufgabe angesehen. Über die letzten Jahre lässt sich zwar ein Trend vom geduldeten Sonderfall zur wohlwollenden Annäherung beobachten. Und doch wird in den Köpfen (auch der Weiterbildungsakteure selbst) immer noch eine Grenze zwischen den traditionellen Aufgaben der Universität (Lehre, Forschung, Dienstleistung) und der Weiterbildung gezogen. Weiterbildung wird oft als eine „Aufgabe besonderer Art“ bezeichnet. Demgegenüber ist es aus einer Perspektive des lebenslangen Lernens kaum verständlich, dass sie anders positioniert wird als die Lehre in den Bachelor- und Masterstudiengängen, nämlich als Teil eines integralen Auftrages „Lehre“ – allerdings mit eigenständigen Merkmalen!

Humane Orientation as a New Cultural Dimension of the GLOBE Project: A Validation Study of the GLOBE Scale and Out-Group Humane Orientation in 25 Countries

We validate, extend, and empirically and theoretically criticize the cultural dimension of humane orientation of the project GLOBE (Global Leadership and Organizational Behavior Effectiveness Research Program). Theoretically, humane orientation is not just a one-dimensionally positive concept about being caring, altruistic, and kind to others as discussed by Kabasakal and Bodur (2004), but there is also a certain ambivalence to this concept. We suggest differentiating humane orientation toward in-group members from humane orientation toward out-group members. A multicountry construct validation study used student samples from 25 countries that were either high or low in humane orientation (N = 876) and studied their relation to the traditional GLOBE scale and other cultural-level measures (agreeableness, religiosity, authoritarianism, and welfare state score). Findings revealed a strong correlation between humane orientation and agreeableness, welfare state score, and religiosity. Out-group humane orientation proved to be the more relevant subfacet of the original humane orientation construct, suggesting that future research on humane orientation should make use of this measure instead of the vague original scale. The ambivalent character of out-group humane orientation is displayed in its positive correlation to high authoritarianism. Patriotism was used as a control variable for noncritical acceptance of one’s society but did not change the correlations. Our findings are discussed as an example of how rigid expectations and a lack of tolerance for diversity may help explain the ambivalent nature of humane orientation

What's Happening? Allan Kaprow and Claes Oldenburg Argue About Art And Life

In 1961 Allan Kaprow (1927–2006) and Claes Oldenburg (b. 1929) exchanged a number of letters in which they argued about the definition of their avant-garde practices as Happenings. Kaprow, who first introduced this "root-metaphor," as he would later call it, describes with it the necessity of the respective activity to be as far removed as possible from all motives, materials, and formats conventionally connected to art. Oldenburg, who at the time of this exchange was just as active in the New York performance scene as Kaprow, disagrees with his colleague's removal of their practice from the artistic sphere. Oldenburg is also dissatisfied with the fact that Kaprow, through his writings, launches a critical discourse that follows his own definition of the Happening. The two artists thus argue just as much about the positioning of their practices with respect to art as over the authority to establish such a position. This essay traces their argument through their written conversation and in doing so exposes the immense influence Kaprow's rhetoric had on the subsequent art-historical canonization of their respective practices: Oldenburg's more ambivalent position is today amalgamated with Kaprow's theoretical stance.

Men Between: The Role of Zambian Broadcasters in Decolonisation

This article traces the history of a group of Zambian broadcasters who established the first radio station in the country and made their mark on broadcasting for years to come. It describes their contribution to modern Zambian culture and to nationalist mobilisation. African broadcasters developed formats, ways of presenting and choices of music that appealed to Zambian listeners and established new, authentically local styles. While radio quickly established itself as an integral part of everyday life and culture in the colony, its effect was highly ambivalent. Broadcasters at the same time undermined and enforced the colonial project of using the medium as a transmitter of modernisation ideology. The article explores Thomas Turino’s characterisation of this team as ‘cosmopolitans’ and shows how they were influenced by BBC ideas of journalism and modernisation ideology. To do so, it analyses the relationships African broadcasters had with Europeans in senior positions and with colonial and postcolonial governments. This shared value system brought these Zambian broadcasters into conflict with the post-independence government and its plans to bureaucratise radio, despite their nationalist commitment and strong support for the United National Independence Party (UNIP) before independence.
