Intimate partner violence,health, sexuality,and academic performance among a national sample of undergraduates

ABSTRACT

Objective: To determine the association between intimate partner violence (IPV) and academic performance among heterosexual and sexual minority undergraduates, including whether health mediates this relationship. Participants: A national sample of undergraduate students aged 18–24 years old who completed the 2011–2014 National College Health Assessment IIb (N = 85,071). Methods: We used structural equation modeling to create a latent variable of IPV victimization (stalking, physical, sexual, and emotional violence) in order to test its relationship with health (physical and mental) and two indicators of academic performance (GPA and perceived academic difficulties), according to participants’ sexual identity (heterosexual, lesbian, gay, bisexual, and unsure). Results: Regardless of sexual identity, undergraduates who reported IPV were more likely to have lower GPA and increased academic difficulties. Health mediates this relationship, such that IPV reduces health, which negatively affects performance. Conclusions: IPV poses a serious threat to undergraduates’ health and educational success. Findings warrant universal prevention and intervention.     

Bootstrapping Spatial Median for Location Problems

In multivariate location problems, the sample mean is most widely used, having various advantages. It is, however, very sensitive to outlying observations and inefficient for data from heavy tailed distributions. In this situation, the spatial median is more robust than the sample mean and could be a reasonable alternative. We reviewed several spatial median based testing methods for multivariate location and compared their significance level and power through Monte Carlo simulations. The results show that bootstrap method is efficient for the estimation of the covariance matrix of the sample spatial median. We also proposed bootstrap simultaneous confidence intervals based on the spatial median for multiple comparisons in the multi-sample case.     

Hygiene, Medicine, and Modernity in Korea, 1876–1910

Modernity in relation to medicine and the body is central to discussions on modernity in Korea. I have chosen to write this paper I have already penned several writings that are related to the topic: modern hygiene, cleanliness, medical service, and medicine. First topic is about the contrast between premodernity and modernity by comparing the prevalence of cholera in the early nineteenth and the early twentieth century. I discussed the new Western hygiene to control cholera decisively contributing to the destruction of the Confucian worldview and the generation of a new colonial modern order as well as preventing an epidemic, cholera. Second topic is about the dichotomy between cleanliness—cultured and uncleanliness—barbarity. Because it was related to the five senses, the discourse of uncleanliness and cleanliness could bring about an immediate effect, which made it the most elementary and primary discourse of modernity in Korea. Third topic is about premodern bodies in topknots and modern bodies in short hair. From among the incidents and topics that I studied then, the most impressive and extreme case regarding the relationship between the body and hygiene was that of the Cut Topknot Act (斷髮令). According to this decree, there were two main reasons for cutting off topknots: hygiene and convenience. Underlying them is the idea that long hair harms political reform and national enrichment. Indeed, this legislation had served as the battleground for a fierce war between modern standards and premodern traditions. Fourth topic is about the modernizing phase of health care system in Korea between 1876 and 1910. The health care system in Korea underwent tremendous changes from 1876 to 1910. In this process, the recently imported Western practices gradually came to occupy the center and existing practices were delegated to the periphery. Final topic is about the sanitation movement that believers of Ch’ ǒntokyo initiated around the twentieth century. This voluntary movement was greatly different from the two external and forced modernizations by Japanese imperialism and Western missionaries.

The factoring likelihood method for non-monotone missing data

We address the problem of parameter estimation in multivariate distributions under ignorable non-monotone missing data. The factoring likelihood method for monotone missing data, termed by Rubin (1974), is applied to a more general case of non-monotone missing data. The proposed method is asymptotically equivalent to the Fisher scoring method from the observed likelihood, but avoids the burden of computing the first and second partial derivatives of the observed likelihood. Instead, the maximum likelihood estimates and their information matrices for each partition of the data set are computed separately and combined naturally using the generalized least squares method. A numerical example is presented to illustrate the method.     

An RKHS framework for functional data analysis

Linear combinations of random variables play a crucial role in multivariate analysis. Two extension of this concept are considered for functional data and shown to coincide using the Loève–Parzen reproducing kernel Hilbert space representation of a stochastic process. This theory is then used to provide an extension of the multivariate concept of canonical correlation. A solution to the regression problem of best linear unbiased prediction is obtained from this abstract canonical correlation formulation. The classical identities of Lawley and Rao that lead to canonical factor analysis are also generalized to the functional data setting. Finally, the relationship between Fisher's linear discriminant analysis and canonical correlation analysis for random vectors is extended to include situations with function-valued random elements. This allows for classification using the canonical Y scores and related distance measures.     

Does a Self-Affirmation Intervention Reduce Stereotype Threat in Black and Hispanic High Schools?

The risk of confirming negative stereotypes about one’s social group, known as stereotype threat, depresses academic achievement among students of color and contributes to racial gaps in achievement. Some work finds that stereotype threat may be alleviated through self-affirmation exercises, translating into improved performance among students vulnerable to threat. However, this work has been conducted primarily in settings where students of color represent a relatively small segment of the student population. The current study explores whether this intervention is efficacious in schools where students of color are the majority. Through a randomized controlled trial of 886 students in three high schools (one predominantly black, one predominantly Hispanic, and one mixed race school), we administered self-affirmation exercises over the course of an academic year. We find no clear evidence that self-affirmation promoted higher standardized test scores or higher grades within the sample. The null findings highlight the complex nature of academic challenges in segregated contexts and raise important questions about the nature of stereotype thereat in such contexts. Importantly, this suggests that solely enhancing self-integrity may not be sufficient to close academic race-based gaps.     

Resilience and Decision‐Making Strategies as Predictors of Career Decision Difficulties

The purpose of this study was to examine resilience and decision‐making strategies as predictors of difficulties experienced during the career decision‐making process. College students (N = 364) responded to measures of resilience, career decision‐making strategies, and career decision difficulties. Results indicated that resilience and decision‐making strategies accounted for 46% of the variance in career decision difficulties. Resilience had a greater influence on problems encountered during decision making than on problems encountered at the outset of the process. Different decision‐making strategies appeared to be related to difficulties encountered at different stages of the decision‐making process. For example, aspiration for an ideal occupation was positively associated only with lack of readiness. Procrastination was the only strategy related to all three decision difficulties: lack of readiness, lack of information, and inconsistent information. The results indicated the importance of decreasing procrastination at all stages of decision making and the need to promote resilience to deal with decision difficulties.     

Queer Blindfolding: A Case Study on Difference “Blindness” Toward Persons Who Identify as Lesbian,Gay, Bisexual,and Transgender

The purpose of this article is to introduce and explore the narrative strategy of queer blindfolding. Utilizing psycho-discursive qualitative methodology, the authors will draw from a case study to demonstrate how some beneficent, well-intended persons who identify as heterosexual adopt the narrative strategy of queer blindfolding as they negotiate the discourse of heteronormativity. We will map this narrative strategy, compare and contrast it to racial colorblindness, and unpack the accompanying intra-psychic conflict and defense mechanisms that are utilized by the participant in the case study. We will also demonstrate how this discursive strategy positions participants within systemic heterosexism.     

Contingency,conflict, crisis: Strategy selection of religious public relations professionals

A national survey among religious public relations practitioners working for mainstream Protestant Christian churches was undertaken to examine strategic options in a conflict or crisis. Religious public relations professionals tend to employ collaborating, contending or compromising in a conflict with a given public, while they are likely to use concession or corrective action in a crisis. Internal contingent factors are mostly associated with accommodating, avoiding, concession or corrective action strategies, while contending is most often correlated with external contingent factors.
