The gallon-jug shelf-transfer test: an instrument to evaluate deteriorating function in older adults

This study examined the validity, reliability, and discriminatory capacity of the gallon-jug shelf-transfer (GJST) test. Six hundred fifty-three independent-living older adults (463 women age 72.9 +/- 7.0 years, 190 men age 74.3 +/- 6.7 years) participated. Participants moved five 1-gallon jugs (approximately 3.9 kg) from a knee-high to a shoulder-high shelf as quickly as possible. The GJST showed an exponential performance decline with age, and there were significant correlations between the GJST and common functional tests (p<.001). High within-day and between-days reliability was detected. The test also detected differences resulting from training status (p<.01) and training protocols (p<.05). The GJST is a valid, reliable, inexpensive, safe, and easily administered clinical test for identifying physically vulnerable elders who could benefit from interventions such as exercise to improve their physical capacities and maintain independence.     

The extended satisfaction with life scale: Development and psychometric properties

The development and psychometric properties of the Extended Satisfaction With Life Scale (ESWLS) are described in detail. The ESWLS is a 50-item self-report scale that measures satisfaction with life in nine domains. It can be completed by most people in under 20 minutes and can be used by researchers and clinicians. The readability of the ESWLS was estimated to be between the seventh and tenth grade levels. Internal consistency, estimated by coefficient α, ranged from 0.81 to 0.96 for the individual subscales. Two-week test-retest reliability coefficients ranged from 0.74 to 0.87. Results of exploratory and confirmatory factor analyses strongly supported the factor structure of the ESWLS. Preliminary evidence of convergent and discriminant validity is provided as well as preliminary norms.     

Anticipating Likely Consequences of Lottery‐Based Affirmative Action*

Objectives. To better understand the consequences of whole or partial reliance on test scores as a screening mechanism for college or university admissions or for job placement or promotion. Methods. We introduce a simple hurdles/threshold model to study one particular mechanism that has been recently proposed to generate a “compromise” between race‐normed or gender‐normed standards for acceptance, on the one hand, and the decision to select those with the highest score regardless of race or gender, on the other—a method we call lottery‐based rules with minimum thresholds of acceptance. Results. We show the factors that determine how close acceptance rates for the disadvantaged group under lottery‐based methods will be to the acceptance rates under either race‐normal or pretest‐score‐based mechanisms. Conclusions. We argue that the likely consequences of using this method are not nearly as attractive as they might first appear to reformers.     

I agreed to go because........examining the Agency of Children within a phenomenon conceptualised as trafficking in Ghana

The legal and policy framework on child trafficking is dismissive of children's agency and regards them as vulnerable personalities. This paper examines the scope of children's agency in their transportation to other communities for fishing in Ghana. Using a phenomenological design, 17 child returnees' views were elicited on their movement for fishing activities. Findings revealed that children's agentive capabilities progressed primarily from consent giving to negotiation. Highlighting the relational and material context within which children's agency unfolds, the study suggests that it is erroneous to generally ascribe the discursive label of ‘innocence’ to children who are considered as trafficked.     

ADDRESSING THE IMPLEMENTATION PROBLEM: A GAMING APPROACH

Traditionally decision sciences has been plagued with the problem of implementation, i.e., transforming a sound theoretical technique into an operational system. Most researchers who study the problem concentrate on identifying factors which relate to implementation or on identifying the change process required to achieve implementation. In a recent study, Sorensen and Zand [24] demonstrate that the Lewin-Schein change theory explains the process necessary for achieving implementation. While the Lewin-Schein theory explains the required change process, the theory does not address the question of how one brings about change. The purpose of this article is to describe a “gaming” approach for accomplishing change. A case example is given to demonstrate the proposed implementation methodology.     

The role of visa class in the location choices of immigrants in Australia at the regional and neighbourhood scales

Australia’s pro-immigration policies have played a vital role in national population growth, serving to address what would otherwise be chronic labour shortages and population ageing. While migrants to Australian have shown a clear preference for cities and tend to locate with co-ethnics, variations by visa class—employment, family reunification, and asylum—have yet to be fully explored. This paper aims to identify variations in settlement patterns of immigrants in Australia by visa types and the factors underpinning these choices, paying particular attention to ethnic networks and employment opportunities. We apply a series of negative binomial regressions to aggregate census data linked to visa status. At the suburb level, our results show the importance of the presence of compatriots in shaping the location choices of family migrants, with the exception of skilled and humanitarian immigrants from China, Malaysia and Thailand. At the regional level, skilled migrants, including skilled regional migrants, respond to employment opportunities to a greater extent than family and humanitarian migrants.

     

Early social referencing predicts object mastery motivation in infancy: Social antecedents of object mastery motivation

The researchers sought to understand the typical development of social referencing and object mastery motivation in infancy and to determine the relationship between social referencing and object mastery behaviors in infants from 7 to 22 months of age. The study included 36 infants who were followed as part of a longitudinal study of at-risk infants but were not determined to need care in the neonatal intesive care unit at birth. Both mastery behaviors of persistence and success showed a statistically significant effect of age, while social behaviors remained stable from 7 to 22 months. Social behaviors at 7 and 10 months were correlated with persistence at 22 months and success at 16 to 22 months demonstrating that early social referencing predicts object mastery behaviors in later infancy. Further research should determine if this trend extends to early childhood.     

A HEURISTIC PROCEDURE FOR DETERMINING IN-PROCESS INVENTORIES

Most prior studies that examine in-process inventory requirements associated with a manufacturing facility employ an optimizing algorithm; this article proposes a heuristic procedure for determining such requirements. A procedure is given for determining “active” and “banked” work-in-process requirements. The two are combined to give total in-process requirements. A key factor presented in the paper is the relationship between in-process inventory requirements and the “balancing” of a production facility. Most prior researchers examine these problems independently. It will be shown that both problems can be resolved concurrently. The concepts are applicable to both an existing as well as a new manufacturing facility.
