Individual differences in vulnerability to subjective time distortion1

Time duration is perceived to be longer when accompanied by dynamic sensory stimulation than when accompanied by static stimulation. This distortion of time perception is thought to be due to the acceleration of an internal pacemaker that has been assumed to be the main component of temporal judgments. In order to investigate whether the function of the internal pacemaker is modality dependent or independent, we examined the correlation of visual flicker and auditory flutter effects on a temporal production task. While seeing a 10‐Hz visual flicker or hearing a 10‐Hz auditory flutter, participants estimated a duration of 2500 ms as accurately as possible by pressing a button. The results showed a significant within‐individual correlation between the time distortion due to visual flicker and that due to auditory flutter. Additionally, we found that time distortion due to auditory flutter tended to be larger in female participants than in male participants. These results suggest that the mechanisms underlying subjective time dilation are similar between vision and audition within individuals, but that they vary across individuals.     

Dopamine regulation of human speech and bird song: a critical review

To understand the neural basis of human speech control, extensive research has been done using a variety of methodologies in a range of experimental models. Nevertheless, several critical questions about learned vocal motor control still remain open. One of them is the mechanism(s) by which neurotransmitters, such as dopamine, modulate speech and song production. In this review, we bring together the two fields of investigations of dopamine action on voice control in humans and songbirds, who share similar behavioral and neural mechanisms for speech and song production. While human studies investigating the role of dopamine in speech control are limited to reports in neurological patients, research on dopaminergic modulation of bird song control has recently expanded our views on how this system might be organized. We discuss the parallels between bird song and human speech from the perspective of dopaminergic control as well as outline important differences between these species.     

Keeping People In or Out?

Abstract : In this article I argue that the Lutheran doctrine of two kingdoms provides a good basis for the legitimate participation of all citizens in political discourse and decisions, no matter what faith they hold. The argument is backed by selected insights from philosopher Jürgen Habermas and sociologists Linda Woodhead and Paul Heelas. Against this backdrop, I suggest some challenges for a theology that addresses issues related to religion and society.     

Reorganization of personal identity in the context of motivational dynamics and internal dialogical activity

Identity is constantly constructed and reconstructed. It may be assumed that there are six fundamental motivational goals according to which it is organized: self‐esteem, self‐efficacy, continuity, distinctiveness, belonging, and meaning (Vignoles, 2011 ). Moreover, identity is shaped by its dialogical nature (Hermans, 2003 ; van Halen & Janssen, 2004 ). The longitudinal study was conducted to examine both the motivational and the dialogical basis of identity structure dynamics. The results showed that the more the identity element was connected with a sense of continuity and the more dialogical it was, the greater the perceived centrality of this element was after two months. Furthermore, the more the identity element satisfied the self‐esteem and belonging motives, the more positive was the affect ascribed to it. In the behavioral domain of identity, participants more strongly manifested those identity aspects that were earlier rated as more dialogical and satisfying the motive of belonging. The results showed that the motivational underpinnings of identity along with its dialogical nature explain changes in identity structure.     

Attitudes towards seeking psychological help among a sample of Turkish university students: the roles of rumination and internal working models

The current study investigates how attitudes towards seeking psychological help relate to internal working models of attachment (self-model and other-model) and ruminative tendencies. The study includes 589 Turkish university students (278 females, 308 males and 3 unknown) by implementing a convenient sampling procedure. The average age of the participants was 22.4 years (SD = 2.2). Participants were administered the Attitudes toward Seeking Psychological Help-Short, the Relationship Questionnaire and the Rumination Scale. The results of the study indicate that the other-model and rumination have a relationship to women's help-seeking attitudes whereas the self-model has a relationship to men's help-seeking attitudes. The results are discussed in light of the related literature.     

Theory and teen dating violence victimization: Considering adolescent development

Teen dating violence is an important public health problem, with implications for the future health and well-being of adolescents. However, most work on teen dating violence has developed separately from literature on normative adolescent romantic relationships and development; understanding teen dating violence within the framework of adolescent psychosocial development may provide new areas for research. Thus, the present paper summarizes five theories of adolescent development that are relevant to the study of teen dating violence victimization, as well as empirical literature that demonstrates support for key theoretical tenets in research examining adolescent romantic relationships. We also present questions for future dating violence study that arise from these key theoretical tenets and past empirical research. Researchers interested in dating violence victimization can use the presented theories to guide new directions in research inquiry, so that findings are situated within the broader field of adolescent development.     

腹腔镜与开腹肝包虫内囊摘除术的临床对照研究

对腹腔镜和开腹肝包虫内囊摘除术的治疗效果进行比较。选择腹腔镜肝包虫内囊摘除术病例26例及行开腹肝包虫内囊摘除术病例50例,比较其手术时间、术中出血量、胃肠功能恢复时间、术后禁食时间、镇痛药物使用例数、镇痛药物使用时间、并发症发生率及术后住院时间的比较。腹腔镜和开腹组均无手术死亡病例;腹腔镜组术中出血量明显少于开腹组;术后胃肠功能恢复时间、术后禁食时间、镇痛药使用例数及时间、住院天数显著短于开腹组;两组并发症发生率差异无统计学意义。腹腔镜下肝包虫内囊摘除术可以达到与开腹肝包虫内囊摘除术同样的效果,且手术创伤小,恢复快。     

Political Islam and Non-Muslim Religions: A Lesson from Lessing for the Arab Transition

Hardly any region has recently captured the global geopolitical imagination as much as the Arab world after the so-called Arab Spring and very likely no state more so than Egypt. Finally it seemed that democracy was coming to the region, that this would spell the end of radical Islam, and of any local aspirations of creating Islamic states, and mark the beginning of a rapprochement between East and West. This article analyses and links those dynamics, with particular reference to the transition process in the wake of the so-called Arab Revolution, and gauges what may be at stake for members of non-Muslim faiths. It particularly traces the rift between theoretical Muslim discourse about Islamic tolerance towards other faiths and its implementation or the absence thereof in practice. It concludes that so far no real progress has been made and that, for the relationship to evolve, Islam needs to proceed to a state in which it sees itself as no more than an equal to other religions. The recognition of its tradition-based nature and of the consequences that flow from such a realization for the treatment of its fundamental sources, the Qur'an and the Sunna, will be addressed. To evaluate the current situation and the outlook, we shall use the example of the famous eighteenth-century German play by Gotthold Ephraim Lessing, Nathan the Wise, about the occupation of Jerusalem by Saladin.     

Re-charting global ethics

Migrations driven by ethnic, religious, and other forms of social conflict have been common in the past quarter-century, and have in Africa led many to seek refuge and to expect hospitality abroad. This leads to a concern for pluralist ethics, for many receiving refuge abroad expect that they will be able to live by their thoughts and beliefs, creating enclaves of cultural difference. But difference exists in all communities: cultural homogeneity does not exist except in the conservative imagination. Nevertheless, a sameness – the sameness of the value of every person – remains within this plurality. The sameness is conceived in distinct ways in the Natural Law tradition that yields liberalism, in the Golden Rule, in Kant's categorical imperative, and in the Luo culture of Eastern Africa. The Luo precept Luoro remb dhano (‘restraint from letting human blood’) is compared with these other ethical cosmopolitan wellsprings in this essay.
