Oxytocin is used in approximately half of all births in the United States during labor induction and/or augmentation. However, the effects of maternal oxytocin administration on offspring development have not been fully characterized. Here, we used the socially monogamous prairie vole to examine the hypothesis that oxytocin exposure at birth can have long-term developmental consequences. Maternally administered oxytocin increased methylation of the oxytocin receptor (Oxtr) in the fetal brain. As adults, oxytocin-exposed voles were more gregarious, with increased alloparental caregiving toward pups and increased close social contact with other adults. Cross-fostering indicated that these effects were the result of direct action on the offspring, rather than indirect effects via postnatal changes in maternal behavior. Male oxytocin-exposed offspring had increased oxytocin receptor density and expression in the brain as adults. These results show that long-term effects of perinatal oxytocin may be mediated by an epigenetic mechanism.

ArgumentThis paper examines the intersecting histories of psychiatry and psychology (particularly in its clinical guise) in the United States from the second half of the nineteenth century to the present. It suggests that there have been three major shifts in the ideological and intellectual orientation of the “psy complex.” The first period sees the dominance of the asylum in the provision of mental health care, with psychology, once it emerges in the early twentieth century, remaining a small enterprise largely operating outside the clinical arena, save for the development of psychometric technology. It is followed, between 1945 and 1980, by the rise of psychoanalytic psychiatry and the emergence of clinical psychology. Finally, the re-emergence of biological psychiatry is closely associated with two major developments: an emphasis that emerges in the late 1970s on rendering the diagnosis of psychiatric illnesses mechanical and predictable; and the long-term effects of the psychopharmacological revolution that began in the early 1950s. This third period has seen a shift the orientation of mainstream psychiatry away from psychotherapy, the end of traditional mental hospitals, and a transformed environment within which clinical psychologists ply their trade.

Propeller planes and small engine aircraft around the United States, legally utilize leaded aviation gasoline. The purpose of this experiment was to collect suspended particulate matter from a university campus, directly below an airport’s arriving flight path’s descent line, and to analyze lead content suspended in the air. Two collection sets of three separate samples were collected on six separate days, one set in July of 2018 and the second set in January 2019.

Chapter 6 examines the long-term effects of international soft law on policy in the United States since 2008. The extent and type of post-crisis US cooperation with foreign jurisdictions have varied considerably with far-reaching ramifications for international financial markets. Focusing on the international interaction of reforms in banking and derivatives, the chapter uses the book’s approach to understand US regulation in the wake of the Great Recession. The authors attribute seemingly random variation in the US relationship to foreign regulation and markets to differences in pre-crisis international soft law. Here, the existence (or absence) of robust soft law and standard-creating institutions determines the resources available to policy entrepreneurs as well as their orientation and attitudes toward international cooperation. Soft law plays a central role in the evolution of US regulatory reform and its interface with the rest of the world.

Long Term Effects

Argentina’s right-wing shift in the 2015 presidential election concluded twelve years of center-left rule. The elected president, Mauricio Macri, claimed that the economy would experience normalization of existing imbalances and recover its strength in a “new political era.” However, the new administration quickly restored the dominance of neoliberal economic policies through a comprehensive set of initiatives, which centrally included the return to international financial debt and equity markets and submission to the International Monetary Fund’s (IMF) rules. This article analyzes Argentina’s external-debt-growth process and discusses its objectives and long-term effects. This paper posits that the indebtedness process carried out by the Macri administration—and its modality—not only increased the relevance of financial capital in the Argentine economy but also structurally conditioned any future nonorthodox alternative path of development. This outcome cannot be understood without taking into account the deliberate role of the United States, the IMF, and the top companies that operate in Argentina, as well as the complicity of many political sectors.

Meditative Practices

Meditation refers to a state of mind of relaxation and concentration, where generally the mind and body is at rest. The process of meditation reflects the state of the brain which is distinct from sleep or typical wakeful states of consciousness. Meditative practices usually involve regulation of emotions and monitoring of attention. Over the past decade there has been a tremendous increase in an interest to study the neural mechanisms involved in meditative practices. It could also be beneficial to explore if the effect of meditation is altered by the number of years of meditation practice. Functional Magnetic Resonance Imaging (fMRI) is a very useful imaging technique which can be used to perform this analysis due to its inherent benefits, mainly it being a non-invasive technique. Functional activation and connectivity analysis can be performed on the fMRI data to find the active regions and the connectivity in the brain regions. Functional connectivity is defined as a simple temporal correlation between anatomically separate, active neural regions. Functional connectivity gives the statistical dependencies between regional time series. It is a statistical concept and is quantified using metrics like Correlation. In this study, a comparison is made between functional connectivity in the brain regions of long term meditation practitioners (LTP) and short-term meditation practitioners (STP) to see the differences and similarities in the connectivity patterns. From the analysis, it is evident that in fact there is a difference in connectivity between long term and short term practitioners and hence continuous practice of meditation can have long term effects.

Fight Or Flight

For more than a century, scientists have known that acute stress activates the fight-or-flight response. When your life is on the line, your body reacts instantly: your heart races, your breath quickens, and a cascade of hormones sets off physiological changes that collectively improve your odds of survival. More recently, scientists have come to understand that the fight-or-flight response takes a toll on the brain and the body—particularly when stress is chronic rather than acute. Systems designed to handle transient threats also react to stress that occurs again and again, for weeks, months, or years. It turns out that poverty, abuse, and other forms of adversity repeatedly activate the fight-or-flight response, leading to long-term effects on the immune system and brain, which in turn increase the risk for an array of illnesses, including asthma, diabetes, arthritis, depression, and cardiovascular disease. Pioneering neuroscientist Bruce McEwen called this burden of chronic stress “allostatic load.”
