Green roofs are not created equal: the hydrologic and thermal performance of six different extensive green roofs and reflective and non-reflective roofs in a sub-tropical climate

Green roofs have the potential to retain stormwater on the roof surface and lower the thermal loading on buildings. Because of this, the greatest environmental benefits from green roofs might be achieved in subtropical climates characterized by high temperatures and intense rain events. There is, however, little research to support this. In a replicated study in Texas, we compared the performance of six different extensive green roof designs vegetated with native species, to non-reflective (black) roofs, and reflective (white) roofs. Preliminary hydrologic and thermal profile data indicated not only differences between green and non-vegetated roofs, but also among green roof designs. Maximum green roof temperatures were cooler than conventional roofs by 38°C at the roof membrane and 18°C inside air temperature, with little variation among green roofs. Maximum run-off retention was 88% and 44% for medium and large rain events but some green roof types showed very limited retention characteristics. These data demonstrate indicate that: 1. Green roofs can greatly affect the roof temperature profile—cooling surface layers and internal space on warm days. 2. Green roofs can retain significant amounts of rainfall, this is dependent on the size of the rain event and design and can fail if not designed correctly. We suggest that as green roofs vary so much in their design and performance, they must be designed according to specific goals rather than relying on assumed intrinsic attributes.     

Language,discourse and empowerment: changing approaches to children and young people who have sexually abused others

The sexual abuse of children by other children and young people has gained an increasing profile during the previous decade. It has been increasingly recognised that there has been a significant change in the way that this issue has been responded to, both in philosophy and practice, as research has developed and also as the value base of initial constructions of this behaviour has been questioned. This article describes the development of a project to work with children and young people who have sexually abused from its inception in 1995 to the present, outlining the original assumptions and working practices and the reasoning behind changes. The growth of the project illustrates the changing nature of constructions of this behaviour, along with the introduction of new theoretical approaches to respond to this change. In particular, the changes can be seen to reflect a move away from a ‘modernist’ position and this is discussed. Copyright © 2002 John Wiley & Sons, Ltd.     

Forging the links: (de)constructing chains of behaviours

This paper will discuss an article by Becker and French (2005) in this Journal which proposed the general acceptance of correlations or the ‘links’ between child abuse, animal abuse and domestic violence. Becker and French claim this topic has ‘seen a growth of interest’ (p. 399) over the past two decades and they suggest that organizations across the UK should ‘institutionalize the “links” within policy and practice’ (p. 410). In this paper we question the appropriateness of linking different forms of violence in such a mechanistic and predictive way by drawing on and extending arguments we have made elsewhere. We consider the proposed ‘links’ in terms of assumptions, de?nitions, methods and logic, and raise concerns for a prospective practice which is based on retrospective (and ?awed) research. We aim to appeal to in?uential doubters (social workers, child care workers, animal welfare workers, vets, educators and policy‐makers) in a language of ‘reason’, and we propose that the identi?ed reluctance of professionals in the UK to adopt the rhetoric of ‘links’ can be viewed as an informed and re?ective response. Throughout, we offer a corrective commentary to the ?awed assumptions of the ‘links’ argument and seek to encourage others to remain sceptical about these claims and the suggested implications for practice.

The role of bears and bear ceremonialism in Navajo Orthodox traditional lifeway

The Navajos, who now number over 200,000 in population, are the largest, and one of the most culturally intact Indian tribes in North America. Reigning over a reservation of some 25,000 square miles in size, the Navajos, like many other tribal people have long respected and honored bears as being fellow “being” with whom they share the land. Because of the bears power, intelligence, acute senses, and physical features which closely resemble that of a human, they have also played a major role in Navajo tribal legends and ceremonialism. The purpose of this article is to briefly examine the place of bears and bear ceremonialism within the structure of traditional Navajo beliefs and religious practices.     

Development and immediate impact of a self-instruction curriculum for an adolescent indicated drug abuse prevention trial

This article describes the development and immediate impact of a self-instruction indicated drug abuse prevention program, Project Towards No Drug Abuse (TND). Self-instruction programming often is used to help youth that are at high risk for dropout and drug abuse to complete their high school education, and is a method of choice among educators at alternative high schools. This article describes the justification for the self-instruction program, keys to good programmed self-learning, and how a 12-session health educator delivered program was converted to a self-instruction format. In addition, the immediate impact of a 3-group experimental trial is presented. Health educator led, self-instruction, and standard care control conditions are compared on knowledge change, and the two program conditions are compared on process ratings. Self-instruction programming can be successfully adapted from a health educator-led format, though the lack of student group interaction in this modality may limit its receptivity among students.     

Courtship at the coroner's court

This article examines the nature and conduct of nineteenth-century courtship through the prism of the largest sample of coronial court records ever assembled. These records deal with unexplained or violent deaths and often involved the extensive gathering of testimony from witnesses and other community stakeholders. A surprising number of cases were either directly connected to courtship, or witness statements provide evidence on courtship practice and custom. Focusing particularly on records for the English Midlands, we offer a new model of typologies of courtship experience running across a spectrum from serene and unproblematic through to the obsessive relationship that ended with murder or violence. Dealing in more detail with individual cases, we illustrate the value of the material for understanding the lived experience of courtship and address three broad questions. What range of actors (family, friends, neighbours, employers, lodgers, etc,) was involved in courtships among the labouring classes? What was the emotional context within which the courtships of ‘ordinary people’ were played out? And how did ordinary people experience the human journey of courtship? We suggest that it was possible for men and women to construct completely different versions of courtships, that relationships were fragile, and that the capacity for individual agency in courtship was much more circumscribed than has often been allowed for this period.     

Risky Sexual Behaviors and Pregnancy Outcomes in Young Adulthood Following Substantiated Childhood Maltreatment: Findings From a Prospective Birth Cohort Study

Childhood maltreatment is associated with a range of adverse mental and physical health outcomes, including increased rates of sexually transmitted infections (STIs) later in life. However, the impact on risky sexual behaviors and pregnancy outcomes has not been adequately studied. This is particularly true for physical abuse, emotional abuse, and neglect. We examined associations between prospectively substantiated childhood maltreatment and reports of risky sexual behaviors by men and women, as well as selected pregnancy outcomes in women. We followed up 3,081 (45.7% female) participants from the Mater-University of Queensland Study of Pregnancy, a prospective Australian birth cohort study. Using logistic regression, we examined the association between substantiated childhood maltreatment from birth to 14 years, and self-reported risky sexual behaviors and youth pregnancy outcomes at the 21-year follow-up. In adjusted analyses, children who had experienced multiple childhood maltreatment exhibited more risky sexual behaviors than their nonmaltreated counterparts. In specific models, those exposed to each form of childhood maltreatment, independent of co-occurring forms of childhood maltreatment, had an increased likelihood of risky sexual behaviors, particularly an early sexual debut and, for women, youth pregnancy. Neglect was also associated with multiple sexual partners, and emotional abuse with higher rates of miscarriage. There was no difference between men and women in how different forms of childhood maltreatment predicted risky sexual behaviors in young adulthood. All forms of substantiated childhood maltreatment, including multiple substantiations, were associated with risky sexual behavior in both sexes as well as higher rates of youth pregnancy in women. Moreover, emotional abuse persistently predicted miscarriages in young adult women. Understanding the association between childhood maltreatment and risky sexual behaviors and youth pregnancy outcomes may help suggest preventive strategies.     

Service(s) Marketing Research: Developments and Directions

This paper outlines the development of research in the domain of service(s) marketing from its birth as an area of academic study in the 1960s/1970s to the current time. It identifies four phases of development. Phases 1–3 relate to the period before 2004, which focuses on the development of service(s) marketing. In Phase 4, a greater focus on the concept of service (singular) – defined as the application of knowledge and skills – has resulted in developments and directions in service research that offer a different perspective through which to view more general marketing. This different perspective has explicit implications also for wider business and management research. The paper summarizes current research in this domain, which coalesces around three broad perspectives, namely, the service‐dominant logic of marketing, technology and service, and transformative service research. It concludes by outlining likely trends for service research into the future. Three interrelated directions are suggested: research on service in a changing context; research responding to academic schools of thought; and research responding to consumer trends.
