Hunters and healers: social change and cultural conflict in rural Maine

This is a story of two people with different philosophies concerning use of land and attitudes towards animals. What makes their situation unique is that they share abutting property and live on the same road in a small village in Maine. Phil owns the house and land on which he grew up and has always hunted the surrounding land, including the property more recently acquired by Marie. Marie emigrated from Massachusetts with the intention to create a sanctuary for animals. Their polarized views have resulted in strife between them and illustrate the conflict between hunters and non-hunters in Maine.     

Walk-in Together: A pilot study of a walk-in online family therapy intervention

Many Australians are requiring mental health care, including families, leading to long wait times in order to access support. Walk-in therapy reduces barriers to mental health support services by providing support at the time that families seek help. This paper presents a proof-of-concept study investigating the acceptability and short-term effectiveness of an online walk-in family therapy service, Walk-in Together (WIT). Part 1 of the paper describes the experiences of 44 family members from 22 families who presented to a public family therapy clinic for a virtual walk-in family therapy session. The session was conducted by a team of three experienced family therapists. Family members' experiences were sought pre-session, post-session, and at 6 weeks follow-up via survey and interview. Part 2 of the paper explores therapist perceptions (n = 7) of the WIT approach, through thematic analysis of semi-structured interview data. Post-session feedback showed 85% of family members found WIT to be helpful and 50% were optimistic about their future as a family after their WIT session. Six weeks post-session it was revealed that WIT supported planning for families in equipping them to move forward with 88% of family members reporting that they knew what to do after the session. All therapists uniformly experienced the model as offering a timely and beneficial service, suitable for diverse presentations and constellations of families. These preliminary results suggest the significant utility of this WIT intervention as a well-received and helpful service for families, who valued the easy access and rapid therapeutic response afforded by the online, walk-in delivery model. This proof-of-concept paper suggests the potential for further development and growth of WIT, as well as other mental health support services using a walk-in, telehealth model to meet the rising demand for therapeutic support for families in distress.     

On a Roll: The Process of Initiation and Cessation of Problem Gambling Among Adolescents

As gambling becomes more accessible and acceptable in society, problems associated with gambling and gaming have begun to affect ever increasing numbers of adolescents. Although restricted from most forms of gambling by law, many adolescents are finding a path into problem gambling. Some are becoming compulsive gamblers early in their gambling career, facing a future filled with consequences and problems. Understanding the pathway or process by which these adolescents become engaged in gambling behavior and how they can extricate themselves from this addictive behavior can enhance the efficiency and effectiveness of our interventions. This article offers a perspective on the initiation and cessation of compulsive gambling using the basic elements of the process of intentional behavior change outlined in the Stages of Change from the Transtheoretical Model. The process of initiation of a problematic behavior is similar to the process of modification or cessation of a problematic behavior in terms of these stages of change. With adolescents it is important to distinguish between the process of initiation, which has implications for prevention of gambling problems, and the process of cessation, which often necessitates the assistance of treatment. Creating interventions that parallel the process of change offers the potential for personalizing and potentiating efforts to reduce the prevalence and consequences associated with compulsive or pathological and problem gambling. Application of this model to gambling behavior offers a heuristic that is intriguing and requires substantiation through rigorous research.     

An Exponential-Gamma Convolution Model for Background Correction of Illumina BeadArray Data

Illumina BeadArrays are becoming an increasingly popular Microarray platform due to its high data quality and relatively low cost. One distinct feature of Illumina BeadArrays is that each array has thousands of negative control bead types containing oligonucleotide sequences that are not specific to any target genes in the genome. This design provides a way of directly estimating the distribution of the background noise. In the literature of background correction for BeadArray data, the information from negative control beads is either ignored, used in a naive way that can lead to a loss in efficiency, or the noise is assumed to be normally distributed. However, we show with real data that the noise can be skewed. In this study, we propose an exponential-gamma convolution model for background correction of Illumina BeadArray data. Using both simulated and real data examples, we show that the proposed method can improve the signal estimation and detection of differentially expressed genes when the signal to noise ratio is large and the noise has a skewed distribution.     

A longitudinal study of the effects of a university human sexuality course on sexual attitudes

This study tested the hypotheses that students taking a university human sexuality course will have different attitudes over a 2‐year period than students not taking such a course, and more accepting attitudes toward the sexual behaviors of others, over a 2‐year period, than toward their own sexual behavior. Sexual attitudes of 127 human sexuality class students and 114 control class students at the University of Northern Iowa were measured at the beginning of class (pretest), the end of class (posttest), and 2 years after the end of class (follow‐up). There were no pretest differences between the treatment and control groups in university classification, marital status, political affiliation, religious affiliation, sex, age, grade point average, or sexual attitudes. Both hypotheses were supported. Human sexuality students developed more accepting attitudes and became more accepting of behaviors for others compared to behaviors for self. Control group students developed less accepting attitudes and became less accepting of behaviors for others compared to behaviors for self. The sex of the students and the session they attended class were also found to influence sexual attitudes.     

Watershed Pollution and Preservation: The Awareness–Appraisal Model of Environmentally Positive Intentions and Behaviors

A two-factor awareness-appraisal model suggests that individuals' reactions to threatening circumstances are shaped by their awareness of the threat and their appraisal of the degree of threat the circumstances pose to them. This approach, applied to watershed conservation, predicts that individuals will be willing to clean up the rivers and streams of their watershed if they are familiar with local water features (rivers, streams, ponds, lakes) and if they consider these features of the watershed to be degraded. We tested the model by measuring watershed knowledge, appraisal of watershed quality, value assigned to protecting the watershed, and behavioral intentions regarding watershed preservation in a survey of 1,128 residents of two urban watersheds. The results supported the awareness-appraisal model: Those residents who were aware of their watershed and considered it polluted expressed the strongest pro-preservation behavioral intentions. These relationships were held in both watersheds, but were stronger for those who resided in the more degraded watershed .
