Pregnancy complications and maternal cardiovascular risk: opportunities for intervention and screening?

The link between defective nutrition of the fetus and vascular disease in later life is now well established. Naveed Sattar and Ian Greer report on the intriguing probability that complications in pregnancy also predispose mothers to later vascular and metabolic disease

IMPACT OF ALTERNATIVE GRID PRICING STRUCTURES ON CATTLE MARKETING DECISIONS

Quality grade, yield grade, and other feedlot performance factors explain much of the variation in profit under grid pricing. Thus, feedlot owners can change profits by adjusting time on feed to influence these performance factors. This research uses growth models, logistic regression, and an optimization process to determine how the optimal number of days on feed changes under different grid pricing structures. It was found that large quality or small yield discounts increases the optimal number of days on feed and small quality or large yield discounts result in fewer days on feed. Losses associated with a grid having large quality discounts are minimized as cattle fed for more days are able to obtain Choice premiums despite the discounts for more Yield Grade 4 and 5 carcasses. Given small quality discounts, cattle fed for a shorter length of time can obtain the Yield Grade 1 and 2 premiums without a large loss in revenue due to grading Select or Standard. Under cash pricing, cattle are fed for very long periods because there are no discounts applied to the carcasses and, therefore, the more weight they gain, the more revenue they generate. During periods of low feed prices, cattle can be fed longer so more cattle grade Prime but also have more Yield Grade 4 and 5 cattle.grid pricing, profits, animal growth, logistic regression, days on feed, Livestock Production/Industries, Marketing,

Understanding the links of Mindfulness, Relationship Satisfaction, and Sexual Satisfaction

The purpose of the present study was to examine the relationship between mindfulness and its link to sexual satisfaction and relationship satisfaction. Data were collected from 809 individuals (18.8% bisexual, 60.7% straight, 19.2% gay/lesbian) in romantic relationships. Participants completed an online survey to measure mindfulness (five facets: observing of experience, describing with words, acting with awareness, non judging of inner experience, non reactivity to inner experience), sexual satisfaction, and relationship satisfaction. Results from two multivariate analyses (predicting sexual satisfaction and relationship satisfaction) revealed that relationship satisfaction is significantly predicted by three of the five facets of mindfulness – acting with awareness, describing with words, and non judging of inner experience. Sexual satisfaction was significantly predicted by the non judging of inner experience facet of mindfulness. Non judging of inner experience was the only facet that significantly predicted both relationship and sexual satisfaction. These findings indicate that when individuals are able to take a non-evaluative stance towards their sensations, cognitions, and emotions, they are more likely to be satisfied. Future research and clinical intervention for improving satisfaction may benefit from focusing on mindfulness related to the non judging of inner experience. Implications for clinical practice and future research will be discussed

Fundamental Differences in Mechanical Behavior between Two Types of Crystals at the Nanoscale

We present differences in the mechanical behavior of nanoscale gold and molybdenum single crystals. A significant strength increase is observed as the size is reduced to 100 nm. Both nanocrystals exhibit discrete strain bursts during plastic deformation. We postulate that they arise from significant differences in the dislocation behavior. Dislocation starvation is the predominant mechanism of plasticity in nanoscale fcc crystals, while junction formation and hardening characterize bcc plasticity. A statistical analysis of strain bursts is performed as a function of size and compared with stochastic models

Efficacy of a Workbook to Promote Forgiveness: A Randomized Controlled Trial with University Students

Objective The present study investigated the efficacy of a 6-hour self-directed workbook adapted from the REACH Forgiveness intervention. Method Undergraduates (N = 41) were randomly assigned to either an immediate treatment or waitlist control condition. Participants were assessed across 3 time periods using a variety of forgiveness outcome measures. Results The 6-hour workbook intervention increased forgiveness, as indicated by positive changes in participants’ forgiveness ratings that differed by condition. In addition, benchmarking analysis showed that the self-directed workbook intervention is at least as efficacious as the delivery of the REACH Forgiveness model via group therapy. Conclusion A self-directed workbook intervention adapted from the REACH Forgiveness intervention provides an adjunct to traditional psychotherapy that could assist the mental health community to manage the burden of unforgiveness among victims of interpersonal harm
