Despite many decades of research of diodes, which are fundamental components of electronic and photoelectronic devices with p-n or Schottky junctions using bulk or 2D materials, stereotyped architectures and complex technological processing (doping and multiple material operations) have limited future development. Here, a novel rectification device, an orientation-induced diode, assembled using only few-layered black phosphorus (BP) is investigated. The key to its realization is to utilize the remarkable anisotropy of BP in low dimensions and change the charge-transport conditions abruptly along the different crystal orientations...

Drawing on intergroup threat theory and the stereotype content model, we examine intergroup relations in an organizational context. We surveyed 108 Asian immigrants working at a large international organization located in the UK. We found that perceptions of warmth and competence interact to predict minority group members' willingness to interact with an outgroup majority. Extending previous research, we demonstrate that warmth and competence differentially affect intergroup uncertainty, which mediates the relationship between stereotype content and willingness to interact with the outgroup...

As gaming culture continues to marginalize women and people of color, other gamers are also highlighting the inequalities they face within digital gaming communities. While heterosexism and homophobia are commonplace within gaming culture, little is known about the actual experiences of "gaymers" and even less about "gaymers" of color. As such, this article seeks to explore lesbians of color and their experiences "gayming" out and online. Exploring identity development, community building, and connectivity via social networking, the women within this study articulate what it means to be lesbian online and how this impacts their physical and digital experiences...

Objectives: Chronic lymphocytic leukemia (CLL) is the most common type of leukemia in Western populations, being rarer in Asian and African people. It has been suggested that patients with CLL from Africa might have a more aggressive disease compared with white patients. In this study, we aimed to identify genetic factors that may account for this difference. Methods: We analyzed immunoglobulin heavy chain (IGH) genes' mutational status by performing next-generation sequencing in 25 Senegalese and 50 Italian patients with CLL...

Repetitive sensory motor behaviors are a direct target for clinical treatment and a potential treatment endpoint for individuals with intellectual or developmental disabilities. By removing the burden associated with video annotation or direct observation, automated detection of stereotypy would allow for longer term monitoring in ecologic settings. We report automated detection of common stereotypical motor movements using commercially available accelerometers affixed to the body and a generalizable detection algorithm...

This article explores medical, midwifery, and nurse practitioner students' attitudes about women who may consume alcohol throughout their pregnancies. Twenty-one health care students responded to a scenario-based vignette addressing alcohol consumption during pregnancy, as well as a semistructured interview, which were analyzed using Braun and Clarke's thematic analysis approach. Two primary themes related to students' attitudes concerning alcohol consumption during pregnancy were identified: (a) divergent recommendations for different women, based on perceptions of their level of education, culture/ethnicity, and ability to stop drinking; and (b) understanding the social determinants of health, including the normalization of women's alcohol consumption and potential partner violence...

The primary aim of this study is to increase the existing knowledge about the pragmatic skills of children with autism spectrum disorders (ASD). Specifically, the study has two objectives. The first is to provide a profile of characteristics based on The Children's Communication Checklist (CCC-2) pragmatics scales (inappropriate initiation, stereotyped language, use of context, nonverbal communication, and general pragmatics) and narrative task indicators. To this end, children with ASD will be compared to children with typical development (TD), controlling the effects of sex and structural language (speech, syntax, semantics, coherence)...

BACKGROUND: The stereotype of the student with dyspraxia as 'clumsy and disorganised' may cause clinical teachers to be concerned about the student's performance in a clinical environment; however, if it is understood that dyspraxic students possess many strengths, as well as weaknesses, it may be that some stereotypical myths will be dispelled and more effective support offered to them. This review considers research surrounding the experiences of students and health professionals with dyspraxia within higher education (HE), alongside the personal experiences of EW, in order to inform the development of clinical teachers with respect to their support for learners with dyspraxia...

BACKGROUND: Children with autistic spectrum disorder (ASD) frequently present with inattention, impulsivity and hyperactivity, which are the cardinal symptoms of attention deficit hyperactivity disorder (ADHD). The effectiveness of methylphenidate, a commonly used ADHD treatment, is therefore of interest in these children. OBJECTIVES: To assess the effects of methylphenidate for symptoms of ADHD (inattention, impulsivity and hyperactivity) and ASD (impairments in social interaction and communication, and repetitive, restricted or stereotypical behaviours) in children and adolescents aged 6 to 18 years with ASD...

Brain activity during sleep is fairly ubiquitous and the best studied possible function is a role in memory consolidation, including motor memory. One suggested mechanism of how neural activity effects these benefits is through reactivation of neurons in patterns resembling those of the preceding experience. The specific patterns of motor activation replayed during sleep are largely unknown for any system. Brain areas devoted to song production in the songbird brain exhibit spontaneous song-like activity during sleep, but single cell neural recordings did not permit detection of the specific song patterns...

People often search for cues in the environment to determine whether or not they will be judged or treated negatively based on their social identities. Accordingly, feedback from gatekeepers-members of majority groups who hold authority and power in a field-may be an especially important cue for those at risk of experiencing social identity threat, such as women in math settings. Across a series of studies, women who received positive ("Good job!") versus objective (score only) feedback from a male (vs. female) authority figure in math reported greater confidence; belonging; self-efficacy; more favorable Science, Technology, Engineering, and Mathematics (STEM) attitudes/identification/interest; and greater implicit identification with math...

BACKGROUND: Pain is reported in approximately 50-70% of cancer patients. Studies on gender differences in perceived pain generally report lower pain thresholds and increased pain prevalence in women, which may be attributed to gender-specific behaviors, stereotypes, and unknown etiological factors. There are sparse and inconclusive results on gender differences in self-perceived pain in the cancer setting. The aim of this article was to examine the effect of gender on baseline perceived pain intensity in cancer patients through a meta-analysis...

Theists often receive the benefit of being stereotyped as trustworthy and moral, whereas atheists are viewed as untrustworthy and immoral. The extreme divergence between the stereotypes of theists and atheists suggests that mental images of the two groups may also diverge. We investigated whether people have biased mental images of theists and atheists. The results suggest that mental images of theists are associated with more positive attributes than images of atheists (Study 1), and these mental images influence who is believed to behave morally and immorally (Study 2)...

Diverse motivational triggers, including diet, elicit stereotypic behavior. We investigated whether diets comprised of different protein levels but similar levels of energy were associated with the occurrence of locomotor stereotypies in the striped mouse Rhabdomys dilectus chakae. In a first experiment, 20 stereotypic and 20 non-stereotypic (10 subjects per sex and per group) juvenile (40 days old) subjects were placed on baseline (BP), high (HP) or low protein (LP) diet treatments (120 subjects in total)...

Background: People with non-epileptic seizures (NES) describe challenging relationships with health professionals, and explain negative interactions as common and expected. Despite these difficulties, little is known about how people with NES experience difficult healthcare encounters. Methods: Using a thematic discourse analysis approach, we analysed the free-text survey responses of 135 people with NES and asked: what kind of challenges do people living with this condition encounter when interacting with health professionals, and how do they experience the consequences of difficult interactions? We explore their experiences by interpreting the latent meaning of participants' texts from a social-constructionist perspective on health and illness...

Background: Stigmatizing attitudes to mental illness, and especially schizophrenia, are not limited to the general population but are also common among health professionals. Health professionals are in a position to model health related attitudes both in the general public and patients. Medical students are an interesting group to focus upon, since they are future health professionals and correcting stigmatizing attitudes is still possible during their educational curriculum. Methods: This study investigated the attitude toward mental illness in medical students at the Iuliu Hatieganu University of Medicine and Pharmacy...

Despite global progress in HIV stigma reduction, persistent HIV stigma thwarts effective HIV service delivery. Advances in HIV biomedical research toward a cure may shift perceptions of people living with HIV and HIV stigma. The purpose of this study was to examine how men who have sex with men (MSM) living with HIV in Guangzhou, China perceive HIV cure research and its potential impact on MSM and HIV stigma. We conducted in-depth interviews with 26 MSM living with HIV about their perceptions of HIV cure research and the potential impact of an HIV cure on their lives...

Beside locomotion, search movements are another important type of motor activity of insects. They are very often performed by the front legs of the animals. They consist of cyclic stereotypical leg movements that can be modified by sensory signals. The details of the local organization of these movements have however not yet been studied. In this paper, we, using an appropriate variant of our existing one-leg model, present a scheme of how these searching movements might be organized and performed on the level of local neuromuscular control networks...
