A Cross-Cultural Look at Co-rumination, Self-Disclosure, Friendship, Relational Concerns and Emotional Adjustment
Rose (2002) first defined co-rumination as extensive problem-focused talk, and it has been found to be associated with both depression/anxiety and friendship quality. However, our understanding of co-rumination is limited by an exclusive focus on Western samples of mostly children/adolescents. Thus, the primary aim of the current study is to investigate the construct validity of co-rumination in an Asian sample by examining associations among rumination, co-rumination, emotional adjustment, self-disclosure and friendship quality. We predict that Asians will report lower levels of co-rumination, and we expect gender differences in co-rumination to replicate cross-culturally.
224 Asian students (69 men, 153 women) from universities in Hong Kong and East China and 118 U.S. students (43 men, 75 women) from a private college in the Northwest participated in the study.
Expected gender differences were found. Significant positive relationships emerged between co-rumination, self-disclosure, friendship quality, and rumination in both samples. Asian students reported significantly higher levels of co-rumination but lower levels of self-disclosure. Asians reported higher levels of relational concerns than U.S students. Relational concerns partially mediated cultural differences in self-disclosure but not in co-rumination. Surprisingly, co-rumination was unrelated to adjustment and did not predict unique variance in anxiety/depression beyond the effects of rumination.
The current findings highlight the complexity of co-rumination as an interpersonal process vs. support-seeking functions in Asians. With limited research on co-rumination in emerging adults, it is unknown whether unique sampling issues or a meaningful developmental shift accounts for the lack of associations between co-rumination and anxiety/depression among U.S. students. Regardless, future longitudinal research should incorporate strategies (e.g., observational data, time sampling) that extend beyond self-report. These designs promise to sharpen our understanding as they more fully capture the dynamic forces at play in co-rumination that may vary across time and culture
NDM-505: DEVELOPMENT OF THE ASCE/SEI STANDARD FOR THE ESTIMATION OF TORNADO WIND SPEEDS
Development of the new ASCE/SEI consensus standard for wind speed estimation in tornadoes began in 2014 and is currently underway. The intent of the new standard is to standardize the methods used to estimate the wind speeds in tornadoes including improvements and expansions for the damaged-based Enhanced Fujita Scale (EF Scale), with potential to extend the scope of the standard to include other windstorms. The standard will include sections on the EF Scale, radar measurements, tree fall pattern analysis, data archives, forensic engineering analysis, in-situ measurements (anemometry), and remote-sensing applications. Users of the standard will include wind, structural and forensic engineers, meteorologists, climatologists, forest biologists, risk analysts, hazards modellers, emergency managers, building and infrastructure designers, the insurance industry, and the media. The standard is intended for adoption by the National Weather Service and for use by storm study teams and researchers as a guide for conducting storm surveys and analysis of storm data. Development of the standard highlights the current state-of-the art in wind speed estimation and also identifies areas where new research is needed. Development of the standard will include a public ballot period. The standard is scheduled to be completed in 2019
Latitudinal variation in ecological opportunity and intraspecific competition indicates differences in niche variability and diet specialization of Arctic marine predators
Individual specialization (IS), where individuals within populations irrespective of age, sex, and body size are either specialized or generalized in terms of resource use, has implications on ecological niches and food web structure. Niche size and degree of IS of near-top trophic-level marine predators have been little studied in polar regions or with latitude. We quantified the largescale latitudinal variation of population- and individual-level niche size and IS in ringed seals (Pusa hispida) and beluga whales (Delphinapterus leucas) using stable carbon and nitrogen isotope analysis on 379 paired ringed seal liver and muscle samples and 124 paired beluga skin and muscle samples from eight locations ranging from the low to high Arctic. We characterized both withinand between-individual variation in predator niche size at each location as well as accounting for spatial differences in the isotopic ranges of potential prey. Total isotopic niche width (TINW) for populations of ringed seals and beluga decreased with increasing latitude. Higher TINW values were associated with greater ecological opportunity (i.e., prey diversity) in the prey fish community which mainly consists of Capelin (Mallotus villosus) and Sand lance (Ammodytes sp.) at lower latitudes and Arctic cod (Boreogadus saida) at high latitudes. In beluga, their dietary consistency between tissues also known as the within-individual component (WIC) increased in a near 1:1 ratio with TINW (slope = 0.84), suggesting dietary generalization, whereas the slope (0.18) of WIC relative to TINW in ringed seals indicated a high degree of individual specialization in ringed seal populations with higher TINWs. Our findings highlight the differences in TINW and level of IS for ringed seals and beluga relative to latitude as a likely response to large-scale spatial variation in ecological opportunity, suggesting species-specific variation in dietary plasticity to spatial differences in prey resources and environmental conditions in a rapidly changing ecosystem

Corresponding morphological and molecular indicators of crude oil toxicity to the developing hearts of mahi mahi
Crude oils from distinct geological sources worldwide are toxic to developing fish hearts. When oil spills occur in fish spawning habitats, natural resource injury assessments often rely on conventional morphometric analyses of heart form and function. The extent to which visible indicators correspond to molecular markers for cardiovascular stress is unknown for pelagic predators from the Gulf of Mexico. Here we exposed mahi (Coryphaena hippurus) embryos to field-collected crude oil samples from the 2010 Deepwater Horizon disaster. We compared visible heart defects (edema, abnormal looping, reduced contractility) to changes in expression of cardiac-specific genes that are diagnostic of heart failure in humans or associated with loss-of-function zebrafish cardiac mutants. Mahi exposed to crude oil during embryogenesis displayed typical symptoms of cardiogenic syndrome as larvae. Contractility, looping, and circulatory defects were evident, but larval mahi did not exhibit downstream craniofacial and body axis abnormalities. A gradation of oil exposures yielded concentration-responsive changes in morphometric and molecular responses, with relative sensitivity being influenced by age. Our findings suggest that 1) morphometric analyses of cardiac function are more sensitive to proximal effects of crude oil-derived chemicals on the developing heart, and 2) molecular indicators reveal a longer-term adverse shift in cardiogenesis trajectory
Characterizing a rare neurogenetic disease, SLC13A5 citrate transporter disorder, utilizing clinical data in a cloud-based medical record collection system
Introduction: SLC13A5 citrate transporter disorder is a rare autosomal recessive genetic disease that has a constellation of neurologic symptoms. To better characterize the neurologic and clinical laboratory phenotype, we utilized patient medical records collected by Ciitizen, an Invitae company, with support from the TESS Research Foundation.Methods: Medical records for 15 patients with a suspected genetic and clinical diagnosis of SLC13A5 citrate transporter disorder were collected by Ciitizen, an Invitae company. Genotype, clinical phenotypes, and laboratory data were extracted and analyzed.Results: The 15 patients reported all had epilepsy and global developmental delay. Patients continued to attain motor milestones, though much later than their typically developing peers. Clinical diagnoses support abnormalities in communication, and low or mixed tone with several movement disorders, including, ataxia and dystonia. Serum citrate was elevated in the 3 patients in whom it was measured; other routine laboratory studies assessing renal, liver and blood function had normal values or no consistent abnormalities. Many electroencephalograms (EEGs) were performed (1 to 35 per patient), and most but not all were abnormal, with slowing and/or epileptiform activity. Fourteen of the patients had one or more brain magnetic resonance imaging (MRI) reports: 7 patients had at least one normal brain MRI, but not with any consistent findings except white matter signal changes.Discussion: These results show that in addition to the epilepsy phenotype, SLC13A5 citrate transporter disorder impacts global development, with marked abnormalities in motor abilities, tone, coordination, and communication skills. Further, utilizing cloud-based medical records allows industry, academic, and patient advocacy group collaboration to provide preliminary characterization of a rare genetic disorder. Additional characterization of the neurologic phenotype will be critical to future study and developing treatment for this and related rare genetic disorders

Curricular Factors that Unintentionally Affect Learning in a Community-Based Interprofessional Education Program: The Student Perspective
Background: The Dalhousie Health Mentors Program (DHMP) is a community-based, pre-licensure interprofessional education initiative that aims to prepare health professional students for collaborative practice in the care of patients with chronic conditions. This program evaluation explores the studentsâ 1) learning and plans to incorporate skills into future practice; 2) ratings of program content, delivery, and assignments; 3) perspectives of curricular factors that inadvertently acted as barriers to learning; and 4) program improvement suggestions.Methods: All students (N = 745) from the 16 participating health programs were invited to complete an online mixed methods program evaluation survey at the conclusion of the 2012â2013 DHMP. A total of 295 students (40% response rate) responded to the Likert-type questions analyzed using descriptive and non-parametric statistics. Of these students, 204 (69%) provided responses to 10 open-ended questions, which were analyzed thematically.Findings: While the majority of respondents agreed that they achieved the DHMP learning objectives, the mixed-methods approach identified curriculum integration, team composition, and effectiveness of learning assignments as factors that unintentionally acted as barriers to learning, with three key student recommendations for program improvement.Conclusions: Educators and program planners need to be aware that even well-intended learning activities may result in unintended experiences that hamper interprofessional learning
