The Epistemic Culture of Homebrewers and Microbrewers

Homebrewing and microbrewing have been growing in popularity during the last few decades. One way this phenomenon can be analyzed is through the culture of knowledge production. We use the subfield of science and technology studies (STS) to examine homebrewing and microbrewing in this light. Early STS was interested in the social construction of scientific facts within daily practices of scientists. Through these early studies, STS revealed not only the process of scientific fact creation but also existence of “epistemic cultures.” Our study investigates the epistemic culture of homebrewers and microbrewers. Analysis of this epistemic culture was accomplished through use of in-depth interviews with homebrewers and microbrewers at several regional sites. Three major themes emerged from the data: home space as lab; the art and science of beer brewing; and brewing as “friendship”. These themes establish a foundation for understanding the shared epistemic culture existing between homebrewers and microbrewers.     

Infant–Mother and Infant–Caregiver Emotional Relationships: Process Analyses of Interactions in Three Contemporary Childcare Arrangements

Emotional relationships in infant–mother dyads in families where mothers provided full‐time childcare were compared with those of families where mothers used in‐home childcare providers and family childcare providers (N = 245). Infant relationships with childcare providers were also studied. Emotional relationships were adequate in all three childcare arrangements, but infant–mother dyads in in‐home childcare arrangements displayed healthier emotional relationships than infant–mother dyads in mother care arrangements; no differences in the health of emotional relationships with infants emerged among the three types of childcare providers (mother care, in‐home childcare, family childcare). Infant–mother dyads in in‐home childcare arrangements also displayed healthier emotional relationships than infant–in‐home childcare caregiver dyads, but infant–mother and infant–caregiver dyads were comparable in family childcare families. Emotional relationships in infant–mother and infant–caregiver dyads were not correlated, regardless of the type of childcare.     

Baan Mankong participatory slum upgrading in Bangkok, Thailand: Community perceptions of outcomes and security of tenure

A key problem facing slum dwellers is tenure insecurity - as well as the threat of eviction, residents are excluded from many services extended to legal residents, from water connections to public schooling. Thailand’s Baan Mankong slum upgrading program adopts a people-driven approach to resolving problems of insecure housing and poor living conditions, putting slum residents at the core of the process. This paper explores, through interviews, how residents in four Bangkok communities perceive the outcomes of upgrading, particularly their new homes and tenure situation. Participant satisfaction is key to ensuring successful scaling up of Baan Mankong, as this is done through community-driven exchange and learning-by-doing. The results show that while the respondents appreciate their new houses and improved living environment, they are wary of the resulting debt burden. While tenure is regarded as secure in the short term, the long-term situation is not so clear. Homes cannot be sold on outside the community, and therefore Baan Mankong is valued more for improving shelter and strengthening community cohesiveness, rather than as a profit-driven financial investment.     

Undeclared Work in Non-Profit Sports Clubs: A Mixed Method Approach for Assessing the Size and Motives

Non-market economy including volunteer work is often ignored in estimations of the shadow economy because no money changes hands. Whilst volunteers stricto sensu are not paid for their activities, a tendency is noted that legal frameworks do allow for reimbursement for actual expenses incurred. However, if the latter receive reimbursements beyond the scope of regulations and labour law this can also be regarded as undeclared work. In this article, the size and motives of this type of undeclared work in non-profit sports clubs in Flanders (Belgium) are explored. As this kind of informal work, by its nature, is difficult to measure, a mixed method approach was used. The results show that at least 10% of volunteers can be considered as undeclared workers. The tax and social security contribution burdens are considered as the main causes for this undeclared work. It is argued that a new employment status for paid volunteers in sports is necessary to guarantee the provision of qualitative sports services.     

Water sources of urban trees in the Los Angeles metropolitan area

In semi-arid cities, urban trees are often irrigated, but may also utilize natural water sources such as groundwater. Consequently, the sources of water for urban tree transpiration may be uncertain, complicating efforts to efficiently manage water resources. We used a novel approach based on stable isotopes to determine tree water sources in the Los Angeles basin, where we hypothesized that trees would rely on irrigation water in the soil rather than develop deep roots to tap into groundwater. We evaluated the oxygen (δ¹⁸O) and hydrogen (δD) isotope ratios of xylem water, irrigation water, soil water, and groundwater in a study of temporal patterns in water sources at two urban sites, and a study of spatial patterns at nine urban sites and one “natural” riparian forest. Contrary to our hypothesis, we found that despite frequent irrigation, some trees tap into groundwater, although in most species this was a small water source. Some trees appeared to be using very shallow soil water at <30 cm depth, suggesting that these mature urban trees were quite shallowly rooted. In the natural site, trees appeared to be using urban runoff in addition to shallow soil water. We were able to identify tree uptake of precipitation at only 3 sites. The results show that some irrigated trees utilize groundwater and do not rely solely on irrigation water, which may make them able to withstand drought and/or water conservation measures. However, some irrigated trees may develop very shallow root systems, which may make them more susceptible.     

Patterns of Intimate Partner Violence and Sexual Risk Behavior among Young Heterosexually Active Men

Intimate partner violence (IPV) victimization is linked to sexual risk exposure among women. However, less is known about the intersection of IPV perpetration and sexual risk behavior among men. This study used data from a diverse, community sample of 334 heterosexually active young men, aged 18 to 25, across the United States to examine whether and how men with distinct IPV-related behavior patterns differed in sexual risk–related behavior and attitudes. Participants were recruited and surveyed online, and grouped conceptually based on the types of IPV perpetration behavior(s) used in a current or recent romantic relationship. Groups were then compared on relevant sexual risk variables. Men reporting both physical abuse and sexual coercion against intimate partners reported significantly higher numbers of lifetime partners, higher rates of nonmonogamy, greater endorsement of nonmonogamy, and less frequent condom use relative to nonabusive men or those reporting controlling behavior only. This group also had higher sexually transmitted infection (STI) exposure compared to men who used controlling behavior only and men who used sexual coercion only. Findings suggest that interventions with men who use physical and sexual violence need to account for not only the physical and psychological harm of this behavior but also the sexual risk to which men may expose their partners.     

Prevention of child abuse and neglect and improvements in child development

The aim of the study was to evaluate the implementation of a section in the Danish Social Assistance Act which encourages local authorities to offer families services in order to support children at risk of child maltreatment. The specific purpose of the present paper is to answer the question: Will the socio‐psychological development of children known to social services be improved when abuse and neglect are reduced? A sample of 1,138 children was drawn at random from new social services cases starting in 1998. Subsequently, about 80 per cent were evaluated by local caseworkers on the basis of a standardised questionnaire covering a period of four years. The most damaging family conditions seemed to be psychological maltreatment, physical/sexual abuse and neglect. Maltreated children were more often in a depressed state, unhappy, socially isolated, or they had an eating disorder, inadequate or under‐nutrition, suicidal tendencies, lack of concentration, or disturbed behaviour, compared to those children who were not exposed to abuse and neglect. If parental behaviour improved, effects on children's well‐being were also observed and positive changes in children's socio‐psychological development were identified. The questionnaire explored the impact of various interventions, including services geared to strengthen the child's network, but results indicated that the child displayed reduced risk of reactive symptoms only when parental behaviour improved and abuse and neglect were reduced.
