REPLICATION OF A CHOICE MODEL

This study provides an operational replication of a proposed multiattribute choice model. The necessity of replication in the decision sciences in general and in consumer behavior in particular is discussed. Several alternative forms of multiattribute choice models are considered. Results are supportive of earlier efforts in this area.     

Desiring Self‐Determination in Research and Beyond: Parental Consent Requirements and Situated Ethics for Migrant Young People Living amid Changing Family Dynamics

How are procedural research ethics complicit in homogenising and paternalising young people? Through a youth‐centred ethnographic study completed in Canada, I illustrate how migrant young people's complex experiences of family separation, responsibility, and autonomy sit in relation to parental consent requirements for research. By complicating notions of childhood and critically discussing capacity to consent, I elucidate how procedural ethics can negate diversity among young people and perpetuate the structural barriers some face in determining their lives. More flexible ethical procedures and responses could reduce barriers and better accommodate young people's inclusion by recognising their specific circumstances, desires and competencies through heightened contextual awareness.     

Analyzing the results of a cloud-seeding experiment in tasmania

We considered the analysis or a randomized cloud seeding experiment of lusmania, Where an distributed analysis had been specified before the experiment was carried one. We compare “classical” regression analyses, with and without transformations, with permutation tests based upon double-ratio and variance-ratio statistics. Regression residuals are used to compare the merits of various other alternative test-statistics including some based upon gamma distribution assumptions. We conclude that more attention needs to be paid to the relative weights which various rest statistics implicitly attach to low, medium and high rainfalls, and that, irrespective ot distributional assumptions and theory, significant testing should be done using permutation tests.     

Physical activity patterns in healthy middle-aged women

ABSTRACT

Exercise in healthy female adults around the menopausal transition has been routinely examined in leisure activities alone, potentially discounting the physical activity (PA) that is accumulated in household and outdoor domains. The purpose of this study was to quantify PA in healthy middle-aged women and to examine the extent to which the Center for Disease Control (CDC) PA guidelines were met through leisure, household, and outdoor activities. Methods: 440 healthy women, 51–64 years old, BMI ≥18.5 or < 40 kg/m², participated in the study using the Lifetime Physical Activity Questionnaire (LPAQ) to quantify PA. Results: 25.91% met the CDC PA guidelines if leisure time alone was examined. When multiple domains were included, 73.41% of the women met the PA guidelines. This percentage is much higher than the reported 20.6% of U.S. adults who met the guidelines in 2011. PA in women may be underrepresented in data limited to leisure time PA.     

An Empirical Analysis of Rock Climbers' Response to Hazard Warnings

This paper reports the results of a field test of the hazard warning system used in rock climbing. The system is succinct; it differentiates between magnitudes of hazard; and it establishes a "warnings vocabulary." The empirical hazard response models include an "individuating factor," which influences the likelihood of injury, and the severity of injury as independent variables. The models indicate that climbers do assess a "personal" probability of injury and incorporate the hazard warning message when choosing climbing routes. Climbers of greater technical ability are more likely to climb hazardous routes, but they mitigate the likelihood of the hazardous outcome by reducing the technical difficulty of the hazardous route chosen. The response increases with the degree of hazard involved.     

The gift-exchange and reciprocity of women in donor-assisted conception

This paper explores the rhetoric of gift‐exchange as it pertains to the donation of ovarian eggs (oocytes) and participation in surrogate pregnancy arrangements. It does so by drawing on the analysis of interviews with New Zealand women engaged in these practices. Contrary to the view that women's reproductive gift‐giving is intrinsically coercive and exploitative, the narrative accounts of donors involved in this research tend to suggest that women's moral identities as ethical subjects are created in the donative process. Despite this, many anxieties and contradictions involving the exchanges of women involved in donor‐assisted reproduction remain. This paper discusses some of these complexities in light of perceptions and theorisations of the gift relationship.
