Disgust sensitivity relates to attitudes toward gay men and lesbian women across 31 nations

Previous work has reported a relation between pathogen-avoidance motivations and prejudice toward various social groups, including gay men and lesbian women. It is currently unknown whether this association is present across cultures, or specific to North America. Analyses of survey data from adult heterosexuals ( N = 11,200) from 31 countries showed a small relation between pathogen disgust sensitivity (an individual-difference measure of pathogen-avoidance motivations) and measures of antigay attitudes. Analyses also showed that pathogen disgust sensitivity relates not only to antipathy toward gay men and lesbians, but also to negativity toward other groups, in particular those associated with violations of traditional sexual norms (e.g., prostitutes). These results suggest that the association between pathogen-avoidance motivations and antigay attitudes is relatively stable across cultures and is a manifestation of a more general relation between pathogen-avoidance motivations and prejudice towards groups associated with sexual norm violations

Çukurova Bölgesi (Kilikya) nde Orta Tunç Çağı döneminden Genç Tunç Çağı Zaman dilimine kadar uzanan süreçte yerleşim düzeninde meydana gelen değişiklikler.

The Çukurova Region (Cilicia) is an alluvial plain enriched by the rivers of Seyhan and Ceyhan, surrounded by the Taurus mountain range in the North and West and the Amanos Mountains in the east; and stretching from the skirts of the Bolkar-Aladağ massif to Mediterranean Sea at its southern most extension. The region is thus an inaccessible marginal zone except only reachable through several mountains passes from the Anatolian Plateau or from the sea through the harbour towns. The research subject of this thesis is to evaluate the region and the changes in the settlement pattern, covering the time period from the Middle Bronze Age (ca. 1900-1650 B.C.) to the end of Late Bronze Age (ca. 1200 B.C.) by using Geographical Information Systems (GIS) to analyse archaeological survey data. Data sets are collected from old and recent archaeological surveys and spatially analysed under a set of parameters (density and proximity) in order to define the habitation patterns throughout the mentioned time periods. An effort was made to challenge the theory that settlement pattern changes were resulted from the impact of the Imperial Hittite policy in the LBA, and some alternative suggestions are presented.M.S. - Master of Scienc

Toplumdaki cinsel yönden aktif erkek sayısının cinselliğe açık kadın sayısına oranı ve bunun cinsel ilgiyi yanlış yorumlamaya olan etkisi

Cataloged from PDF version of article.Thesis (M.S.): Bilkent University, Department of Psychology, İhsan Doğramacı Bilkent University, 2017.Includes bibliographical references (leaves 34-37).The current thesis investigates the operational sex ratio of the environment and its effects on people’s accuracy in evaluating the sex and commitment intent of others. We conducted a speed meeting experiment in Ihsan Doğramacı Bilkent University’s Psychology Laboratory (N=260), where both men and women evaluated their partner’s sexual intent towards them. Results showed a difference between sexes in the error types they made when they evaluated sexual intent. We did not observe any effect of operational sex ratio between experimental groups. We discuss possible reasons for the absence of this effect and directions for future research.by Dilara Ekin Demirci.M.S

Self-evaluating reinforcement learning based spectrum management for cognitive Ad Hoc networks

Demirci, Cihan (Dogus Author) -- Conference full title: 27th International Conference on Information Networking, ICOIN 2013; Bangkok; Thailand; 27 January 2013 through 30 January 2013Cognitive radio (CR) is an emerging technology which aims to solve the current wireless spectra problems in terms of efficiency and utilization. CRs should respond adequately to environmental changes in order to operate in a highly efficient manner. Reinforcement learning (RL) is an effective method that entails exploration, followed by exploitation and is used to train CRs to function in unknown environments. However, it also suffers from cases that cannot be easily avoided and recovered from, such as: conservative behavior causing converging to a non-ideal state and aggressive exploration that results in disrupting the network. In this paper, we propose a self-evaluating, RL-based spectrum management approach for cognitive ad-hoc networks. We investigate a means to detect environmental changes by having a CR inspect its information consistency and respond accordingly to changes in the environment. We also aim to grant CRs more flexibility in exploration behavior since using this approach will make it easier to remedy any shortcomings caused by aggressive exploration. The benefit of applying our algorithm is demonstrated and comparisons of performances using evaluations of different scopes are also provided to illustrate their impact on the spectrum management. Simulation results show the proposed approach is effective and able to improve the performance by increasing CRs' responsiveness to environmental changes and allowing fast recovery

BIO-INSPIRED MAGNETIC BEADS FOR ISOLATION OF SPERM FROM HETEROGENOUS SAMPLES IN FORENSIC APPLICATIONS

Rapid and efficient processing of sexual assault evidence will accelerate forensic investigation and decrease casework backlogs. The standardized protocols currently used in forensic laboratories require the continued innovation to handle the increasing number and complexity of samples being submitted to forensic labs. Here, we present a new technique leveraging the integration of a bio-inspired oligosaccharide ( i.e., Sialyl‐Lewis X ) with magnetic beads that provides a rapid, inexpensive, and easy-to-use strategy that can potentially be adapted with current differential extraction practice in forensics labs. This platform (i) selectively captures sperm; (ii) is sensitive within the forensic cut-off; (iii) provides a cost effective solution that can be automated with existing laboratory platforms; and (iv) handles small volumes of sample (∼200 μL). This strategy can rapidly isolate sperm within 25 minutes of total processing that will prepare the extracted sample for downstream forensic analysis and ultimately help accelerate forensic investigation and reduce casework backlogs

Parasite stress and pathogen avoidance relate to distinct dimensions of political ideology across 30 nations

People who are more avoidant of pathogens are more politically conservative, as are nations with greater parasite stress. In the current research, we test two prominent hypotheses that have been proposed as explanations for these relationships. The first, which is an intragroup account, holds that these relationships between pathogens and politics are based on motivations to adhere to local norms, which are sometimes shaped by cultural evolution to have pathogen-neutralizing properties. The second, which is an intergroup account, holds that these same relationships are based on motivations to avoid contact with outgroups, who might pose greater infectious disease threats than ingroup members. Results from a study surveying 11,501 participants across 30 nations are more consistent with the intragroup account than with the intergroup account. National parasite stress relates to traditionalism (an aspect of conservatism especially related to adherence to group norms) but not to social dominance orientation (SDO; an aspect of conservatism especially related to endorsements of intergroup barriers and negativity toward ethnic and racial outgroups). Further, individual differences in pathogen-avoidance motives (i.e., disgust sensitivity) relate more strongly to traditionalism than to SDO within the 30 nations

Body mass index and complications following major gastrointestinal surgery: A prospective, international cohort study and meta-analysis

Aim Previous studies reported conflicting evidence on the effects of obesity on outcomes after gastrointestinal surgery. The aims of this study were to explore the relationship of obesity with major postoperative complications in an international cohort and to present a metaanalysis of all available prospective data. Methods This prospective, multicentre study included adults undergoing both elective and emergency gastrointestinal resection, reversal of stoma or formation of stoma. The primary end-point was 30-day major complications (Clavien\u2013Dindo Grades III\u2013V). A systematic search was undertaken for studies assessing the relationship between obesity and major complications after gastrointestinal surgery. Individual patient meta-analysis was used to analyse pooled results. Results This study included 2519 patients across 127 centres, of whom 560 (22.2%) were obese. Unadjusted major complication rates were lower in obese vs normal weight patients (13.0% vs 16.2%, respectively), but this did not reach statistical significance (P = 0.863) on multivariate analysis for patients having surgery for either malignant or benign conditions. Individual patient meta-analysis demonstrated that obese patients undergoing surgery formalignancy were at increased risk of major complications (OR 2.10, 95% CI 1.49\u20132.96, P < 0.001), whereas obese patients undergoing surgery for benign indications were at decreased risk (OR 0.59, 95% CI 0.46\u20130.75, P < 0.001) compared to normal weight patients. Conclusions In our international data, obesity was not found to be associated with major complications following gastrointestinal surgery. Meta-analysis of available prospective data made a novel finding of obesity being associated with different outcomes depending on whether patients were undergoing surgery for benign or malignant disease
