Role of cross-slipping in formation of edge dislocations in heteroepitaxial systems GeSi-on-Si(001) and Ge-on-InGaAs/GaAs

Edge misfit dislocations (MDs) formed as result of reactions between 60° glissile threading dislocations and 60° MDs lying on an intersecting glide plane were found in strained GeSi-on-Si(001) and Ge-on-InGaAs/GaAs films. It was demonstrated that dislocations penetrating from the InGaAs buffer layer to the strained Ge film can provoke formation of not only 60° MDs, but also edge MDs on the interface even at minor mismatch of the lattice parameters of the film and the InGaAs/GaAs virtual substrate.     

Contributions of Head-Mounted Cameras to Studying the Visual Environments of Infants and Young Children

Head-mounted video cameras (with and without an eye camera to track gaze direction) are being increasingly used to study infants’ and young children's visual environments and provide new and often unexpected insights about the visual world from a child's point of view. The challenge in using head cameras is principally conceptual and concerns the match between what these cameras measure and the research question. Head cameras record the scene in front of faces and thus answer questions about those head-centered scenes. In this “Tools of the Trade” article, we consider the unique contributions provided by head-centered video, the limitations and open questions that remain for head-camera methods, and the practical issues of placing head cameras on infants and analyzing the generated video.     

自尊的遗传性:来自双生子研究的证据

自尊是个体差异的一个重要方面,迄今已有许多研究从行为遗传学角度探讨自尊个体差异的来源。通过梳理现有关于自尊的双生子研究,发现:1)自尊有中等的遗传度,其个体差异来自遗传和非共享环境;2)遗传对自尊的稳定性有较大作用;3)自尊与认知、情感的联系主要源自共同的遗传基础。总之,遗传对自尊具有重要影响。未来双生子研究可拓展到自尊波动性、内隐自尊等领域,并考虑极端人群的遗传特异性和文化对自尊遗传性的影响。     

Uptake of Cardiac Screening and Genetic Testing Among Hypertrophic and Dilated Cardiomyopathy Families

Cardiomyopathy is a genetically and clinically heterogeneous, life threatening disease which affects people of all ages. Recent guidelines provide recommendations for cardiac screening and genetic testing in at-risk relatives, but the uptake and impact of these measures in the United States is unknown. This is a single institution retrospective study that characterizes the uptake of cardiac screening and genetic testing for relatives of a cohort of 57 probands with hypertrophic (HCM) and dilated cardiomyopathy (DCM) who underwent both clinical evaluation and genetic testing. Cardiac screening was indicated for 302 relatives. One hundred and seventy-three (57 %) completed cardiac screening. Forty of the 57 probands were mutation positive and genetic testing was indicated for 213 relatives. Eighty-four (39 %) completed genetic testing. The uptake of cardiac surveillance was greater than the uptake of genetic testing (p?<?0.0001) among relatives of mutation positive probands. Within the group of at-risk, asymptomatic relatives of probands, cardiac screening and genetic testing were positive in 25 % and 40 % of cases, respectively. These data demonstrate the important role and utility of cascade cardiac screening and genetic testing in the care of patients and families with HCM or DCM. The approach to cardiac screening and genetic testing should be family-specific and requires expertise in the genetics of cardiomyopathy.     

Therapeutic Implications of Religious-Related Emotional Abuse

Religion can play a positive role in preventing all types of abuse. Consequently, it is often difficult to believe that religion or a particular manner of religious awareness can also be conducive to the degradation and humiliation of individuals, and that it can be maneuvered to justify abusive behavior. In this article we discuss the emotional repercussions of religious-related abuse in the family, an aspect that is rarely documented in the field of psychotherapy, but has many negative consequences. Religious-oriented emotional abuse is traceable to several levels of human functioning: the individual's internal level of experiencing themselves, the interpersonal and systemic levels, where the individual enters relationships, as well as within the framework of the individual's relationship with God.     

Ethical Considerations for Volunteer Recruitment of Visual Prosthesis Trials

With the development of visual prostheses research from the engineering phase to clinical trials, volunteer recruitment for the early visual prosthesis trials needs to be carefully considered. In this article, we mainly discuss several issues related to volunteer recruitment that had posed serious challenges to the visual prosthesis trials, such as low rates of participants, high expectations and underlying motivations to participate in the visual prosthesis trials as well as the importance of informed consent. When recruiting volunteers for visual prosthesis implants, it is critical that the visual prosthesis researchers should not only take into account the patient’s expectations and motivations, but also make the patients fully aware of the possible benefits and risks involved with their participation, and help patients establish realistic expectations for the early phase of visual prosthesis implantation. Based on these considerations to the challenges, eligible volunteers may be recruited in the preliminary stages of visual prosthesis trials.     

All in faith: Religion as the idiom and means of coping with distress

A survey design was used to examine if there are any differences between a Christian, a Muslim, and a non-religious group in five personality factors (dominance, liveliness, warmth, apprehension, and sensitivity), general well-being, and death anxiety. No significant differences were found with any of the personality factors between the three groups. Religious participants (Christians and Muslims combined) scored significantly higher for general well-being than non-religious participants. Christians scored significantly lower for death anxiety than both non-religious and Muslim groups, and Muslims scored significantly higher than the non-religious group. These findings are discussed with reference to Terror Management Theory. Suggestions for future research include deeper investigation into beliefs of the afterlife and inclusion of more religions into psychological studies.     

Attentional capture by emotional faces in adolescence

Poor decision making during adolescence occurs most frequently when situations are emotionally charged. However, relatively few studies have measured the development of cognitive control in response to emotional stimuli in this population. This study used both affective (emotional faces) and non-affective (letter) stimuli in two different flanker tasks to assess the ability to ignore task-irrelevant but distracting information, in 25 adults and 25 adolescents. On the non-emotional (letter) flanker task, the presence of incongruent flanking letters increased the number of errors, and also slowed participants’ ability to identify a central letter. Adolescents committed more errors than adults, but there were no age-related differences for the reaction time interference effect in the letter condition. Post-hoc testing revealed that age-related differences on the task were driven by the younger adolescents (11-14 years); adults and older adolescents (15-17 years) were equally accurate in the letter condition. In contrast, on the emotional face flanker task, not only were adolescents less accurate than adults but they were also more distracted by task-irrelevant fearful faces as evidenced by greater reaction time interference effects. Our findings suggest that the ability to self-regulate in adolescents, as evidenced by the ability to suppress irrelevant information on a flanker task, is more difficult when stimuli are affective in nature. The ability to ignore irrelevant flankers appears to mature earlier for non-affective stimuli than for affective stimuli.     

汉字形码和音码的整体性对部件识别的影响

本实验从分析汉字整体知觉的具体表现形式入手,通过三个实验探讨字的整体知觉对部件知觉的影响。实验一以分解方式为变量,考查字形整体知觉对部件识别的影响,发现识别不同结构的字的部件之活动受知觉分解路线(如顺读或逆读)的影响。作者认为这种分解方式效应很可能跟部位有关。实验二证实了这一分析,并进而认为部位效应又跟部位与字形整体知觉的紧密程度有关。实验三以语音码为变量,发现成字部件的字音与整体字语音一致者(形声字),其分解知觉成绩比不一致者(非形声字)有明显的优势。这意味着,整体字音知觉的单一性对部件知觉的作用。最后,本研究还考查了部件识别法的有效性,并认为在研究知觉的整体与部分关系问题时,该法不失为一种新的实验范型。
