Yayın Imagined contact facilitates acculturation, sometimes: contradicting evidence from two sociocultural contexts(Educational Publishing Foundation-American Psychological Assoc, 2019-10) Bağcı Hemşinlioğlu, Sabahat Çiğdem; Piyale, Zeynep Ecem; Stathi, SofiaObjective: Imagined intergroup contact has been shown to be an effective tool to improve intergroup relationships in various settings, yet the application of the strategy among minority group members and across cultures has been scarce. The current research aimed to test imagined contact effects on minority group members' acculturation strategies (contact participation and culture maintenance), perceived discrimination, feelings of belongingness, and social acceptance across three studies conducted in the United Kingdom (Study 1) and Turkey (Studies 2 and 3). Method: The sample consisted of Eastern Europeans in Study 1 (N = 63) and Kurds in Study 2 and 3 (N = 66 and 210, respectively). Participants were randomly assigned to 1 of 2 conditions (control vs. imagined contact) and completed measures of acculturation, perceived discrimination, general belongingness, and social acceptance. Results: Findings showed that while imagined contact significantly reduced perceived discrimination and culture maintenance, and increased contact participation and social acceptance among Eastern Europeans (Study 1), it reduced social acceptance and contact participation among Kurds recruited from a conflict-ridden homogeneous setting (Study 2). With a larger and more heterogeneous sample of Kurds (Study 3), these effects occurred only among those with higher ingroup identification. Moreover, in all studies social acceptance mediated the effects of imagined contact on contact participation and perceived discrimination. Discussion. Findings offer important insights about the use of the imagined contact strategy among minority group members and imply the need to take into account the context-dependent nature of contact strategies.Yayın Pedestrian crossing behavior at midblock crosswalks(Elsevier Ltd, 2019-12) Tezcan, Hüseyin Onur; Elmorssy, Mahmoud; Aksoy, GökerIntroduction: This study investigated the pedestrian crossing behavior at midblock crosswalks, in Istanbul. Method: Data were compiled from field studies at four selected crosswalks that were on one-way streets. Three of the crosswalks were located on three-lane streets while the other one was on a two-lane street. By using two-hour video recordings at each crosswalk, information was collected about pedestrian crossing preferences, pedestrian platoons both at curbside and during the crossing, traffic characteristics including volume, crosswalk occupancy and illegal parking, and pedestrian characteristics comprising age, gender and distraction status. These data were stratified with respect to the number of lanes and two multinomial logit models for platooning and individual crossing behavior was estimated for each stratum. Results: The results showed that the likelihood of platooning increases as the traffic volume and platoon size increase. Moreover, pedestrians who waited for little or no at the curbside and started to cross when one or more lanes were occupied generally lost time during the crossing. In terms of policy, the formation of platoons should be prevented by enforcement or demand-responsive traffic signals with push-to-walk buttons, etc. Overall, the study revealed that the presence of midblock crosswalks is questionable.Yayın Cross-group friendships and psychological well-being: A dual pathway through social integration and empowerment(Wiley, 2018-10-01) Bağcı Hemşinlioğlu, Sabahat Çiğdem; Türnüklü, Abbas; Bekmezci, EyüpThis study investigated the associations between cross-group friendships and psychological well-being among a sample of physically disabled adults. A total of 269 disabled people (M-age=39.13, SD=13.80; 114 females, 152 males, 3 unknown) completed questionnaires including the quality of their friendships with non-disabled people, perceived majority group's attitudes towards the minority group, collective self-esteem, collective action tendencies, own outgroup attitudes, and psychological well-being. Findings demonstrated that disabled people's cross-group friendships were directly and indirectly associated with higher levels of psychological well-being via two routes: one by promoting perceived majority attitudes which consequently led to more positive own outgroup attitudes (well-being through social integration hypothesis) and the other by leading to higher levels of collective self-esteem which enhanced collective action tendencies (well-being through empowerment hypothesis). Findings offer important insights into the study of cross-group friendships in relation to the psychological well-being of stigmatized minority group members.Yayın Turkish health policies: past, present, and future(Routledge, 2020-08-18) Oğuz, Ahmet BünyanIn this article, health policies in Turkey from the 1900s to the present are reviewed in light of the available data on the number of health institutions, life expectancy, infant mortality, and state budget allocation. While a significant quantitative development is observed in the provision of health services, the state by far maintained a leading role in the provision of health services until the 1980s, when an initially weak but steady deviation began, significantly increasing its pace from 2002 and creating a new path where the private sector raised its share with the extensive implementation of neoliberal economic policies. The emergence of public-private partnership projects as a financing tool in the health sector, with various models from the 1990s around the world, found its place in the Turkish health system in the form of city hospitals from 2013, creating a new deviation in the provision of health services by the state.Yayın Efficacy, all-cause discontinuation, and safety of serotonergic psychedelics and MDMA to treat mental disorders: a living systematic review with meta-analysis(Elsevier B.V., 2025-12) Højlund, Mikkel; Yılmaz Kafalı, Helin; Kırmızı, Begüm; Fusar-Poli, Paolo; Correll, Christoph U.; Cortese, Samuele; Sabé, Michel; Fiedorowicz, Jess; Saraf, Gayatri; Zein, Josephine; Berk, Michael; Husain, Muhammad I.; Rosenblat, Joshua D.; Rubaiyat, Ruby; Corace, Kim; Wong, Stanley; Hatcher, Simon; Kaluzienski, Mark; Yatham, Lakshmi N.; Cipriani, Andrea; Gosling, Corentin J.; Carhart-Harris, Robin; Tanuseputro, Peter; Myran, Daniel T.; Fabiano, Nicholas; Moher, David; Mayo, Leah M.; Nicholls, Stuart G.; White, Tracy; Prisco, Michele De; Radua, Joaquim; Vieta, Eduard; Ladha, Karim S.; Katz, Jay; Veroniki, Areti A.; Solmi, MarcoSerotonergic psychedelics and 3,4-methylendioxtmethamphetamine (MDMA) are promising treatments for mental disorders with a continuously evolving evidence base. We searched Pubmed/Scopus/clinical trial registries up to 08july2025 for double-blind randomized controlled trials (RCTs) testing MDMA or serotonergic psychedelics in patients with mental disorders. Primary outcomes were change in disease-specific symptoms and all-cause discontinuation. Standardized mean differences (SMD) and relative risk (RR) were estimated using random-effects meta-analysis. Risk of bias (RoB) was assessed with Cochrane’s RoB-tool version 2 and certainty of evidence with GRADE. The review is maintained as living systematic review ( https://ebipsyche-database.org/ ). We included 30 RCTs (1480 participants; female=45.8 %; with psychological support=83.3 %; high RoB=83.3 %). In post-traumatic stress disorder (PTSD), MDMA reduced PTSD symptoms compared to any control ( k = 11; SMD=-0.85 [-1.09; -0.60]; I2=0 %; GRADE=low). In major depressive disorder (MDD), psilocybin/ayahuasca/LSD reduced depressive symptoms ( k = 8; SMD=-0.62 [-0.97; -0.28]; I2=55 %; GRADE=very low). In anxiety disorders, both MDMA and serotonergic psychedelics reduced anxiety symptoms (SMDMDMA=-1.18 [-2.04; -0.32]; I2=0 %; k = 2; GRADE=low and SMDserotonergic=-0.88 [-1.70; -0.06]; I2=54 %; k = 5; GRADE=very low). In alcohol use disorder, neither psilocybin nor LSD reduced abstinence rates ( k = 6; RR=1.42 [0.89; 2.26]; I2=7 %; GRADE=very low). In attention-deficit hyperactivity disorder (ADHD), LSD did not reduce ADHD symptoms ( k = 1; SMD=0.22 [-0.32; 0.76]; GRADE=very low). Moderate certainty in evidence was only found for MDMA on PTSD symptoms when compared to placebo. MDMA/serotonergic psychedelics were not associated with higher risk of all-cause discontinuation (RRMDMA=0.74 [0.32; 1.72]; RRserotonergic=0.81 [0.56; 1.15]). Overall, MDMA/serotonergic psychedelics are promising for the treatment of PTSD, MDD, and anxiety disorders with moderate to large effect sizes. Pragmatic trials, long-term, head-to-head trials exploring the role of psychological support, aiming to identify predictors of response, and accounting for expectancy and functional unblinding are needed. Studies addressing these limitations will likely be required for regulatory approval of psychedelic drugs.
