    Hook up behaviors are sexual behaviors that participants engage in consensually without the expectation of a romantic commitment, and occur frequently in the college context and often co-occur with binge drinking. Research indicates several factors (i.e., alcohol intoxication, type of sexual behavior, specific motives for hooking up, gender) are predictors of negative emotions associated with hook up experiences, such as regret, shame, confusion, and disappointment. Using hooking up as a coping mechanism coupled with experiencing negative emotions due to hook up experiences are associated with aspects of poor mental health such as depression and anxiety. Therefore, the present sought: (1) to examine the relationship between hooking up to cope and negative affect about the most recent hook up experience, (2) to examine the influence of alcohol intoxication on negative affect about the most recent hook up experience, (3) to examine how gender might moderate the effect of the type of sexual behavior on the degree of negative affect for the most recent hookup behavior, and (4) to examine how the relationship between hooking up to cope and negative affect might change based on alcohol use, type of sexual behavior, and gender. Participants were 474 (72% female) uncommitted, heterosexual undergraduate students with at least one hook up in the past 12 months. Findings revealed a positive association between hooking up to cope and negative affect about the most recent hook up experience and that moderate to extreme intoxication moderated that association. Compared to women, males reported lower negative affect about the most recent hook up experience. Clinical implications include targeting binge drinking and coping hook up motives as methods for reducing negative emotions related to hook up experiences for men and women. Future research should investigate the mechanisms involved in the relationship between hooking up to cope, risky sexual behaviors, and negative mental health symptoms

    Objective: In college student samples, the association between depressive symptoms and alcohol-related problems has been found to be mediated by drinking-to-cope motives. Mindfulness-based interventions suggest that mindfulness may attenuate the conditioned response of using substances in response to negative emotional states, and trait mindfulness has been shown to be a protective factor associated with experiencing fewer alcohol-related problems. In the present study, we examined trait mindfulness as a moderator of the indirect associations of depressive symptoms on alcohol-related problems via drinking-to-cope motives. Method: Participants were undergraduate students at a large, southeastern university in the United States who drank at least once in the previous month (n = 448). Participants completed an online survey regarding their personal mental health, coping strategies, trait mindfulness, and alcohol use behaviors. The majority of participants were female (n = 302; 67.4%), identified as being either White non Hispanic (n = 213; 47.5%) or African American (n = 119; 26.6%), and reported a mean age of 22.74 (SD = 6.81) years. Further, 110 (25%) participants reported having a previous and/or current experience with mindfulness mediation. Results: As hypothesized, the indirect effects from depressive symptoms to alcohol-related problems via drinking-to-cope motives were weaker among individuals reporting higher levels of mindfulness than among individuals reporting lower and average levels of mindfulness. Conclusions: The present study suggests a possible mechanism through which mindfulness-based interventions may be efficacious among college students: decoupling the associations between depressive symptoms and drinking-to-cope motives

    Metabolic Profiling of a Mapping Population Exposes New Insights in the Regulation of Seed Metabolism and Seed, Fruit, and Plant Relations

    To investigate the regulation of seed metabolism and to estimate the degree of metabolic natural variability, metabolite profiling and network analysis were applied to a collection of 76 different homozygous tomato introgression lines (ILs) grown in the field in two consecutive harvest seasons. Factorial ANOVA confirmed the presence of 30 metabolite quantitative trait loci (mQTL). Amino acid contents displayed a high degree of variability across the population, with similar patterns across the two seasons, while sugars exhibited significant seasonal fluctuations. Upon integration of data for tomato pericarp metabolite profiling, factorial ANOVA identified the main factor for metabolic polymorphism to be the genotypic background rather than the environment or the tissue. Analysis of the coefficient of variance indicated greater phenotypic plasticity in the ILs than in the M82 tomato cultivar. Broad-sense estimate of heritability suggested that the mode of inheritance of metabolite traits in the seed differed from that in the fruit. Correlation-based metabolic network analysis comparing metabolite data for the seed with that for the pericarp showed that the seed network displayed tighter interdependence of metabolic processes than the fruit. Amino acids in the seed metabolic network were shown to play a central hub-like role in the topology of the network, maintaining high interactions with other metabolite categories, i.e., sugars and organic acids. Network analysis identified six exceptionally highly co-regulated amino acids, Gly, Ser, Thr, Ile, Val, and Pro. The strong interdependence of this group was confirmed by the mQTL mapping. Taken together these results (i) reflect the extensive redundancy of the regulation underlying seed metabolism, (ii) demonstrate the tight co-ordination of seed metabolism with respect to fruit metabolism, and (iii) emphasize the centrality of the amino acid module in the seed metabolic network. Finally, the study highlights the added value of integrating metabolic network analysis with mQTL mapping

    Associations between body composition and fundamental motor skill competency in children

    Abstract Background Evidence supports an inverse relationship between weight status and motor competence, but most work utilizes body mass index as the proxy for weight status. Body mass index fails to account for essential components of body composition, which may be critical for motor performance. The purpose of this investigation was to examine the relationship between fundamental motor skills competency and body composition (i.e., fat mass, fat percentage, and fatfree mass) as measured by bio-electrical impedance analysis and body mass index in children. Methods Two hundred forty-four children from the Southeastern portion of the United States participated in this project (6.05 ± 2.01 years, 53.3% male). Fundamental motor skills were measured using the Test of Gross Motor Development – 2nd edition and body composition was assessed with the Tanita SC-331S Body Composition Analyzer (bio-electrical impedance analysis). Body mass index was calculated using CDC normative growth charts. Results Bio-electrical impedance analysis measures accounted for 23.1%, F(3, 241) = 24.10, p < .001 and 2.7%, F(3, 241) = 2.22, pΒ = .086 variance in locomotor and object control subscales, respectively; body mass index accounted for 8.4% (locomotor) and 0.1% (object control) variance. For the Test of Gross Motor Development -2nd edition total score, bio-electrical impedance analysis measures accounted for 24.4% F(3, 241) = 25.90, pΒ < .001 compared to body mass index which accounted for 7.9% F(1, 244) = 20.86, pΒ < .001 of the variance. Only fat free mass (p < .001) was a significant predictor for locomotor skills and total models for the Test of Gross Motor Development – 2nd edition; BMI was also a significant predictor (pΒ < .001) in both the locomotor and total models. Conclusions Different components of body composition (i.e., fat free mass) were associated with different aspects of fundamental motor skills competency. Excess body fat may be a morphological constraint to proficient locomotor performance when transporting the body through space. In contrast, body composition did not significantly predict object manipulation performance. More work is needed to understand the causality and directionality of this relationship; however, bio-electrical impedance analysis accounts for more variance in fundamental motor skills performance than body mass index in a field-based setting.http://deepblue.lib.umich.edu/bitstream/2027.42/173643/1/12887_2021_Article_2912.pd
