Identity Status,Gender, and Social Comparison Among Young Adults

The aim of this study was to investigate identity status globally and across identity domains among young Swedish adult women and men. Also, potential differences in social comparison among identity statuses were evaluated. The results showed that most of the 124 participants (50% women, M_age 33.29 years) were assigned to an achieved global identity and had made identity-defining commitments across domains. Gender differences in identity status were found in the occupational and parenthood domains. In addition, differences in social comparison orientation were found only in the parenthood domain, whereas those assigned to moratorium scored higher in social comparison than did those assigned to foreclosure and diffusion. These results bring important knowledge to our understanding of identity during young adulthood.     

Secondary traumatic stress in emergency medicine clinicians

Previously called Secondary Traumatic Stress (STS), secondary exposure to trauma is now considered a valid DSM-5 Criterion A stressor for posttraumatic stress disorder (PTSD). Previous studies have found high rates of STS in clinicians who treat traumatically injured patients. However, little research has examined STS among Emergency Medicine (EM) physicians and advanced practice providers (APPs). The current study enrolled EM providers (N = 118) working in one of 10 hospitals to examine risk factors, protective factors, and the prevalence of STS in this understudied population. Most of the participants were physicians (72.9%), Caucasian (85.6%), and male (70.3%) with mean age of 39.7 (SD = 8.9). Overall, 12.7% of the sample screened positive for STS with clinical levels of intrusion, arousal, and avoidance symptom clusters, and 33.9% had at least one symptom cluster at clinical levels. Low resilience and a history of personal trauma were positively associated with positive STS screens and STS severity scores. Borderline significance suggested that female gender and spending ≥10% of one’s time with trauma patients could be additional risk factors. Findings suggest that resilience-building interventions may be beneficial.     

Relationships between gender self-esteem,sexual prejudice,and trans prejudice in cisgender heterosexual college students

Our understanding of sexual prejudice, or prejudice against gay men, lesbian women, bisexual people, and other sexual minorities, has improved substantially over the last few decades. Less is known about the factors that predict trans prejudice, or prejudice against trans people. Using the framework of social identity theory, we examined the relationship between gender self-esteem, sexual prejudice toward gay men and lesbian women, and trans prejudice in a sample of 391 self-identified cisgender heterosexual students from a Midwestern university in the United States. Compared to women, men reported more sexual prejudice, trans prejudice, more prejudice toward gay men than lesbian women, and more violence toward, teasing of, and discomfort around trans women than trans men. Whereas both men and women reported more teasing of trans women than of trans men, men reported more discomfort around trans women and women reported more discomfort around trans men. Gender self-esteem significantly predicted sexual prejudice and trans prejudice in men but not women. Consistent with other research, our results indicate that men's sexual prejudice and trans prejudice may be motivated by similar factors, whereas the predictors of women's prejudice may be more specific to the type of prejudice.     

Study of behavioural and neural bases of visuo‐spatial working memory with an fMRI paradigm based on an n‐back task

The goal of this study was to propose a new functional magnetic resonance imaging (fMRI) paradigm using a language‐free adaptation of a 2‐back working memory task to avoid cultural and educational bias. We additionally provide an index of the validity of the proposed paradigm and test whether the experimental task discriminates the behavioural performances of healthy participants from those of individuals with working memory deficits. Ten healthy participants and nine patients presenting working memory (WM) deficits due to acquired brain injury (ABI) performed the developed task. To inspect whether the paradigm activates brain areas typically involved in visual working memory (VWM), brain activation of the healthy participants was assessed with fMRIs. To examine the task's capacity to discriminate behavioural data, performances of the healthy participants in the task were compared with those of ABI patients. Data were analysed with GLM‐based random effects procedures and t‐tests. We found an increase of the BOLD signal in the specialized areas of VWM. Concerning behavioural performances, healthy participants showed the predicted pattern of more hits, less omissions and a tendency for fewer false alarms, more self‐corrected responses, and faster reaction times, when compared with subjects presenting WM impairments. The results suggest that this task activates brain areas involved in VWM and discriminates behavioural performances of clinical and non‐clinical groups. It can thus be used as a research methodology for behavioural and neuroimaging studies of VWM in block‐design paradigms.     

Iris Marion Young on responsible intervention: reimagining humanitarian intervention

Iris Marion Young took a strong stance against humanitarian intervention and other so-called legitimate instances of what she calls ‘official violence’. Nevertheless, she was also aware that there may be some situations for which military humanitarian intervention should at least be considered. Young was concerned that some states will use their obligation to defend against human rights violations as a mechanism in securing or maintaining global dominance. In addition, she recognized that what counts as a violation of human rights is not uncontroversial; human rights norms and conventions are interpreted, negotiated, and otherwise contested. In this article, I build on Young’s arguments for a social connection model of responsibility by applying it to a situation where a forceful response to violence might be justified. I juxtapose Young’s position with the emerging international standard called ‘the responsibility to protect’ in order to suggest an account of intervention for global governance relations.     

Developing new online calibration methods for multidimensional computerized adaptive testing

Multidimensional computerized adaptive testing (MCAT) has received increasing attention over the past few years in educational measurement. Like all other formats of CAT, item replenishment is an essential part of MCAT for its item bank maintenance and management, which governs retiring overexposed or obsolete items over time and replacing them with new ones. Moreover, calibration precision of the new items will directly affect the estimation accuracy of examinees’ ability vectors. In unidimensional CAT (UCAT) and cognitive diagnostic CAT, online calibration techniques have been developed to effectively calibrate new items. However, there has been very little discussion of online calibration in MCAT in the literature. Thus, this paper proposes new online calibration methods for MCAT based upon some popular methods used in UCAT. Three representative methods, Method A, the ‘one EM cycle’ method and the ‘multiple EM cycles’ method, are generalized to MCAT. Three simulation studies were conducted to compare the three new methods by manipulating three factors (test length, item bank design, and level of correlation between coordinate dimensions). The results showed that all the new methods were able to recover the item parameters accurately, and the adaptive online calibration designs showed some improvements compared to the random design under most conditions.
