Judgments of marital rape as a function of honor culture,masculine reputation threat,and observer gender: A cross-cultural comparison between Turkey,Germany, and the UK

Previous research has shown that there is higher tolerance of violence against women in cultures with salient gender-specific honor norms, especially when the violence occurs in intimate relationships and in response to threat to male honor. The present cross-cultural study (N = 398) extended these findings to sexual aggression (i.e., marital rape) by comparing participants from a culture that emphasizes honor (Turkey) and participants from cultures without strong honor traditions (Germany and Britain). Turkish participants blamed the victim and exonerated the perpetrator more than did German and British participants. In all cultural groups, participants blamed the victim and exonerated the perpetrator more when the husband's reputation was threatened than in the absence of such threat, and in all cultural groups, men blamed the victim and exonerated the perpetrator more than women. Yet, the effect of masculine reputation threat and this pattern of gender differences were somewhat more pronounced among Turkish than German or British participants. Results exploring the predictive role of honor norms at the individual level beyond rape myth acceptance and traditional gender role attitudes revealed that honor norms were the primary predictor of rape perceptions and blame attributions in Turkey (an honor culture), but not in Germany and Britain (dignity cultures) where rape myth acceptance was the strongest predictor. These results provide insights into the cultural factors influencing marital rape judgments in ways that may undermine victim's well-being and fair handling of rape cases, and highlight the domains most urgently in need of potential intervention.     

The effect of different hypertension models on active avoidance learning

This study tested the effects of different hypertension models on active avoidance learning in rats. Three-month-old male Wistar rats were divided randomly into six groups as follows: control (C), sham operated (sham), two kidney-one clip (2K-1C), one kidney-one clip (1K-1C), deoxycorticosterone-salt (DOCA), and N-omega-nitro-L-arginine-methyl ester (L-NAME) groups. Mean arterial blood pressures were significantly higher in four hypertensive groups compared with control and sham groups. The active avoidance training results indicated that hypertension state is associated with learning impairment. Thiobarbituric acid-reactive substances (TBARS) were determined as an indicator of lipid peroxidation in brain and hippocampus. Additionally, brain and hippocampus nitrite levels were studied.     

Social Contact,Academic Satisfaction,COVID-19 Knowledge,and Subjective Well-being Among Students at Turkish Universities: a Nine-University Sample

Adverse effects of COVID-19 are seen not only on the physical health of infected individuals but also on their subjective well-being. Sudden changes in social lives, lockdowns, and shifts towards online education have had a negative impact on many people, especially university students. As part of an international study, the current study focused on the well-being of students at Turkish universities in relation to social contact, academic satisfaction, and COVID-19 knowledge. A total of 7363 students from nine universities (86.6% from state universities, 71.04% female, and 73.52% at bachelor’s level) participated in an online survey. Results revealed that females had lower levels of subjective well-being and academic satisfaction. According to a mediation model in the study, the relationship between social contact and well-being was mediated by academic satisfaction and COVID-19 knowledge. Our findings can guide future researchers, mental health professionals, universities, and policymakers to understand and improve subjective well-being of university students.

     

Ferromagnetism in Kondo lattice models

We report the discovery of a new ferromagnetic phase in the one-dimensional Kondo lattice model for intermediate values of the coupling constant. This new ferromagnetic phase was observed using a non-Abelian density-matrix renormalization group algorithm, which allowed us to measure directly the magnetization of the ground state with high accuracy.     

Anxiety buffer disruption theory: a terror management account of posttraumatic stress disorder

We present anxiety buffer disruption theory (ABDT) and provide a review of current evidence regarding the theory. ABDT is an application of terror management theory to explain diverse reactions to traumatic events and the onset and maintenance of posttraumatic stress disorder (PTSD). It posits that PTSD results from a disruption in one's anxiety-buffering mechanisms, which normally provide protection against anxiety in general and death anxiety in particular. The disruption of these mechanisms leaves the individual defenseless in the face of overwhelming anxiety, which leads to the major symptom clusters of PTSD: re-experiencing, hyper-arousal, and avoidance. According to ABDT, because of the disruption in their anxiety-buffering mechanisms, individuals with PTSD symptoms do not respond to mortality reminders in the defensive ways that psychologically healthier individuals do. We review four sets of studies conducted in four different cultures and with people who have experienced different types of trauma, which reveal this atypical response pattern and lend support to ABDT.     

In Pursuit of Happiness: Empirical Answers to Philosophical Questions

ABSTRACT— In this article, we provide an overview of what various philosophers throughout the ages have claimed about the nature of happiness, and we discuss to what extent psychological science has been able to substantiate or refute their claims. We first address concerns raised by philosophers regarding the possibility, desirability, and justifiability of happiness and then turn to the perennial question of how to be happy. Integrating insights from great thinkers of the past with empirical findings from modern behavioral sciences, we review the conditions and causes of happiness. We conclude our discussion with some thoughts about the future of happiness studies.     

Exact ferromagnetic ground state of pentagon chains

We model conducting pentagon chains with a multi-orbital Hubbard model and prove that well below half filling, exact ferromagnetic ground states appear. The rigorous method we use is based on the transformation of original hamiltonian into positive semidefinite form. This technique is independent of the spatial dimension and does not require integrability of the model. The obtained ferromagnetism is connected to dispersionless bands but in a much broader sense than flat-band ferromagnetism requires, where on every site a Hubbard term is present. In our case, only a small percentage of, even randomly distributed, sites are only interacting.     

Effective Hamiltonian of the two-band Hubbard model: An exact result

An effective Hamiltonian for the two-band Hubbard model was derived by a canonical transformation which was calculated and summed up to infinite order . The transformed Hamiltonian contains terms with strongly renormalized interaction energies. These new interaction energies show sign reversals as a function of the hopping integral in addition to a strong reduction in the charge-transfer gap and a significant increase in the attractive oxygen Hubbard term.     

A new approach to surface photovoltage measurements on hydrogenated microcrystalline silicon layers

A new approach to the surface photovoltage method is demonstrated on thick undoped microcrystalline silicon films grown on different substrates. The model, which includes top as well as bottom space-charge regions, gives a good picture of rather complex experiments and allows good fitting of theoretical curves to experimental results. This method gives us not only the diffusion length of minority carriers but also information on the existence and properties of the space-charge regions in the sample and the results are verified by comparison with the standard procedure.     

Total spin in the density matrix renormalization group algorithm

A new density matrix renormalization group (DMRG) algorithm is presented which conserves the total spin. This is the first time that standard DMRG is extended to exploit fully the symmetries of the Hamiltonian. The obtained general procedure works for any operator, even operators that do not commute with the Hamiltonian. The new method gives substantial improvements over the standard DMRG.
