An Exploration of Racial/Ethnic Differences in the Association between Perfectionism and Disordered Eating in College Students

Perfectionism is a robust risk factor for eating disorders (EDs). Although individually-oriented dimensions of perfectionism are strongly related to eating pathology, less is known about the contribution of parent-oriented dimensions, specifically parental expectations (PE) and parental criticisms (PC). Further, few studies have investigated these effects within racially/ethnically diverse samples. However, PE and PC might be particularly relevant to eating pathology among certain cultural groups, such as those from collectivistic and interdependent societies. This study examined associations among PE, PC, and ED symptoms across racial/ethnic groups. Undergraduates (N=706; 74.8% Female; 48% White, 19.8% Black, 7.1% Latinx, 16% Asian, 9.1% multiracial) completed online surveys assessing perfectionism and ED symptoms. Multiple and logistic regressions examined the association between parent-oriented perfectionism, global eating pathology, loss-of-control (LOC) eating, purging behaviors, and ED risk status (EDE-Q global \u3c 4.0). Analyses were conducted by racial/ethnic group, controlling for gender. Both PE and PC were related to greater ED pathology in students identifying as White (pp=.03), Asian (p=.02), and multiracial (pp=.19). Higher PC was related to a greater likelihood of endorsing LOC eating in White (p=.004) and Black students (p=.05) and purging behaviors in White (p=.004), Asian (p=.04), and multiracial students (p=.03). Greater PC was also associated with ED risk in Asian (p=.03) and multiracial participants (p=.01). Findings indicate that the relations between specific aspects of parent-oriented perfectionism differ among cultural groups and are associated with ED symptoms in college students. PC seemed more relevant to ED pathology than did PE overall. Findings suggest that parent-oriented perfectionism, particularly PC, might be important to include in clinical assessment and treatment with students at-risk of EDs.https://scholarscompass.vcu.edu/gradposters/1039/thumbnail.jp

Bryophytes of Rocky Branch Nature Preserve, Clark County, Illinois

An extensive field survey of the Rocky Branch Nature Preserve in Clark County, Illinois, revealed a total of 52 bryophyte species. Of these, 38 were mosses and 14 were liverworts. Descriptions, habitats and distribution comments, plus a map showing the county distributions for each species in Illinois are included. As a result of this survey, the liverwort Nardia lescurii (Aust.) Underw. is a new addition to the bryoflora of Illinois. There were also several other bryophytes found that were previously unreported for Clark County or the Rocky Branch Nature Preserve. These include Rhynchostegium pulchellum (Hedw.) Robins var. pulchellum, Isopterygium tenerum (Sw.) Mitt., Sphagnum girgensohnii Russ., Jamesoniella autumnalis (DeCand.) Steph. and Geocalyx graveolens (Schrad.) Nees. Two bryophytes that were reported by Vaughan (1941) but not by Arzeni (1947) were relocated. These are the moss Hookeria acutifolia Hook. and the liverwort Solenostoma crenuliformis (Aust.) Steph. The specimens for all the bryophyte species collected are housed in the Stover Herbarium at Eastern Illinois University, Charleston, Illinois

Reaching Harmony Across Indigenous and Mainstream Research Contexts: An Emergent Narrative

Research with indigenous communities is one of the few areas of research encompassing profound controversies, complexities, ethical responsibilities, and historical context of exploitation and harm. Often this complexity becomes overwhelmingly apparent to the early career researcher who endeavors to make meaningful contributions to decolonizing research. Decolonizing research has the capacity to be a catalyst for the improved wellbeing and positive social change among indigenous communities and beyond. The purpose of this critical analysis is to reach harmony across mainstream and indigenous research contexts. We martial critical theory to deconstruct barriers to decolonizing research, such as power inequities, and identify strategies to overcome these barriers. First, we critically analyze the historical context of decolonizing research with indigenous communities. Next, we analyze the concept of “insider” and “outsider” research. We identify barriers and strategies toward finding harmony across indigenous and mainstream research paradigms and contexts

Streambank Erosion

Streambank erosion refers to the removal of soil and other material, such as rock and vegetation, from the streambank (Figure 1). Streambank erosion is a naturally occurring process, but the rate at which it occurs is often increased by anthropogenic or human activities such as urbanization and agriculture. Changes in land use can cause streambanks to erode at rates much faster than those seen in natural, undisturbed systems

It Could Not Be Seen Because It Could Not Be Believed on June 30, 2013

Nineteen Prescott Fire Department, Granite Mountain Hot Shot (GMHS) wildland firefighters (WF) perished in Arizona in June 2013 Yarnell Hill Fire, an inexplicable wildland fire disaster. In complex wildland fires, sudden, dynamic changes in human factors and fire conditions can occur, thus mistakes can be unfortunately fatal. Individual and organizational faults regarding the predictable, puzzling, human failures that will result in future WF deaths are addressed. The GMHS were individually, then collectively fixated with abandoning their Safety Zone to reengage, committing themselves at the worst possible time, to relocate to another Safety Zone - a form of collective tunnel vision. Our goal is to provoke meaningful discussion toward improved wildland firefighter safety with practical solutions derived from a long-established wildland firefighter expertise/performance in a fatality-prone profession. Wildfire fatalities are unavoidable, hence these proposals, applied to ongoing training, can significantly contribute to other well-thought-out and validated measures to reduce them

“It will always continue unless we can change something”: consequences of intimate partner violence for indigenous women, children, and families

Background: Violence against indigenous women and girls is endemic, yet the absence of research on the consequences of this violence from the perspectives of women presents a profound barrier to the development of knowledge, along with violence prevention and mitigation. Although family is central to many indigenous communities, existing research typically examines the consequences of intimate partner violence (IPV) on women or children in isolation, rather than examining its consequences holistically. Objective: The purpose of this article is to identify US indigenous women's perspectives about the impact of IPV on women, children, and families. Method: Data were collected with 29 indigenous women affected by violence from a Southeastern tribe in the United States. As part of a larger critical ethnography, pragmatic horizon analysis of life history interviews revealed the consequences of IPV across multiple levels. Results: Women reported profound psychological consequences resulting from IPV. The majority of women had witnessed IPV in their childhood, providing support for an intergenerational cycle of violence. Women reported psychological consequences on children, which paralleled those reported by women, leaving deep impressions on children across their life course. Consequences on children and whole families were extensive, indicating the negative ramifications of IPV transcended personal boundaries and affected children and families across multiple generations. Conclusions: Given the tight-knit nature of indigenous families and communities, the consequences across individuals and families were noteworthy. However, a dearth in research examining consequences of IPV across levels fails to capture the interconnections of consequences for women, children, and families. Given the centrality of family in many indigenous communities, examining IPV from a holistic perspective that incorporates multiple levels is recommended for IPV research and intervention development

The Detection of Iridium Using Laser-Induced Breakdown Spectroscopy

Although one thinks of a thruster as utilizing both a fuel and an oxidizer, as well as an ignition source to release molecular energy, thrusters exist that combine the fuel and oxidizer in a single fluid. These monopropellant thrusters can utilize either an ignition source or a catalyst to release the molecular energy stored within the propellant. Monopropellant thrusters are especially attractive for space flight systems because they only require a single propellant line which reduces systems weight and complexity. Some monopropellant thrusters, including legacy hydrazine thrusters, and newer thrusters using hydrazine replacements, that utilize a heterogeneous catalyst have experienced performance anomalies due to the degradation of the catalyst bed. At the Air Force Research Laboratory, current state-of-health diagnostic techniques ate being developed to better understand this catalyst bed degradation for the new hydrazine replacement monopropellant, AF-M315E. Laser-induced Breakdown Spectroscopy (LIBS) is being used to detect and quantify active catalyst materials in the exhaust plume, such as iridium. Previous work has been unsuccessful in detecting iridium. However, by shortening the delay settings on the camera detector, the spectrometer used in LIBS will be able to pick up more of the emissions from the laser-ablated sample, leading to the detection of iridium.

(4,7,13,16,21,24-Hexaoxa-1,10-diaza­bicyclo­[8.8.8]hexa­cosa­ne)sodium perchlorate

The title compound, [Na(C18H36N2O6)]ClO4, was isolated and crystallized to understand more fully the ligand’s binding specificity to cations. The cation and anion reside at an inter­section of crystallographic twofold and threefold axes. The carbon atoms in the cation are disordered over two positions in a 3:2 ratio, and the anion is equally disordered over two positions. The geometries of the cation and anion are typical. The compound packs in alternating sheets of discrete cations and anions stacked along the c axis, separated by a distance equal to one-sixth the length of the c axis

A latent variable modeling approach to identifying subtypes of serious and violent female offenders

Females have recently become an important population in research related to serious and violent juvenile offending. Although a small body of research exists on girls in the deep end of the system, very few studies have examined the degree of heterogeneity within high-risk female samples. This study applied latent class analysis (LCA) to identify subgroups of female juvenile offenders based on their self-report of offending profiles (N=133). Results supported a three-class solution with subgroups characterized by patterns of \u27violent and delinquent\u27, \u27delinquency only\u27, and \u27low\u27 offending patterns. The LCA solution was replicated in an independent sample of high-risk females. The \u27violent and delinquent\u27 class was characterized by significantly higher rates of DSM-IV diagnoses for internalizing disorders, affect dysregulation, exposure to violence (within the home, school and neighborhood), and familial histories of criminality. Implications for future research, policy and clinical practice are discussed
