Double beta decay to the first 2+2^+ state within a boson expansion formalism with a projected spherical single particle basis

The Gamow-Teller transition operator is written as a polynomial in the dipole proton-neutron and quadrupole charge conserving QRPA boson operators, using the prescription of the boson expansion technique of Belyaev-Zelevinski type. Then, the $2\nu\beta\beta$ process ending on the first $2^+$ state in the daughter nucleus is allowed via one, two and three boson states describing the odd-odd intermediate nucleus. The approach uses a single particle basis which is obtained by projecting out the good angular momentum from an orthogonal set of deformed functions. The basis for mother and daughter nuclei have different deformations. The GT transition amplitude as well as the half lives were calculated for ten transitions. Results are compared with the available data as well as with some predictions obtained with other methods.Comment: 12 page

Alcoholism and Intimate Partner Violence: Effects on Children’s Psychosocial Adjustment

It is widely recognized that alcoholism and relationship violence often have serious consequences for adults; however, children living with alcoholic parents are susceptible to the deleterious familial environments these caregivers frequently create. Given the prevalence of IPV among patients entering substance abuse treatment, coupled with the negative familial consequences associated with these types of behavior, this review explores what have been, to this point, two divergent lines of research: (a) the effects of parental alcoholism on children, and (b) the effects of children’s exposure to intimate partner violence. In this article, the interrelationship between alcoholism and IPV is examined, with an emphasis on the developmental impact of these behaviors (individually and together) on children living in the home and offers recommendations for future research directions

Men’s Business, Women’s Work: Gender Influences and Fathers’ Smoking

To further understand men’s continued smoking during their partner’s pregnancy and the postpartum period, a study was undertaken to explore women’s perspectives of men’s smoking. Using a gender lens, a thematic analysis of transcribed interviews with 27 women was completed. Women’s constructions of men’s smoking and linkages to masculine and feminine ideals are described. The findings highlight the ways women position themselves both as defenders and regulators of men’s smoking. Femininities that aligned women with hegemonic masculine principles underpinned their roles in relation to men’s smoking and presented challenges in influencing their partner’s tobacco reduction. By positioning the decision to quit smoking as a man’s solitary pursuit, women reduced potential relationship conflict and managed to maintain their identity as a supportive partner. Insights from this study provide direction for developing gender‐specific tobacco reduction initiatives targeting expectant and new fathers. Indeed, a lack of intervention aimed at encouraging men’s tobacco reduction has the potential to increase relationship tensions, and inadvertently maintain pressure on women to regulate fathers’ smoking. This study illustrates how gender‐based analyses can provide new directions for men’s health promotion programmes and policies. &nbsp

Biological Contribution to Social Influences on Alcohol Drinking: Evidence from Animal Models

Social factors have a tremendous influence on instances of heavy drinking and in turn impact public health. However, it is extremely difficult to assess whether this influence is only a cultural phenomenon or has biological underpinnings. Research in non-human primates demonstrates that the way individuals are brought up during early development affects their future predisposition for heavy drinking, and research in rats demonstrates that social isolation, crowding or low social ranking can lead to increased alcohol intake, while social defeat can decrease drinking. Neurotransmitter mechanisms contributing to these effects (i.e., serotonin, GABA, dopamine) have begun to be elucidated. However, these studies do not exclude the possibility that social effects on drinking occur through generalized stress responses to negative social environments. Alcohol intake can also be elevated in positive social situations, for example, in rats following an interaction with an intoxicated peer. Recent studies have also begun to adapt a new rodent species, the prairie vole, to study the role of social environment in alcohol drinking. Prairie voles demonstrate a high degree of social affiliation between individuals, and many of the neurochemical mechanisms involved in regulation of these social behaviors (for example, dopamine, central vasopressin and the corticotropin releasing factor system) are also known to be involved in regulation of alcohol intake. Naltrexone, an opioid receptor antagonist approved as a pharmacotherapy for alcoholic patients, has recently been shown to decrease both partner preference and alcohol preference in voles. These findings strongly suggest that mechanisms by which social factors influence drinking have biological roots, and can be studied using rapidly developing new animal models
