Calibration of accelerometer output for adults.

Abstract: This paper reviews the collective experience of monitor calibration studies in adults and seeks to answer the following questions: What has been done? What have we learned? What could be done to further enhance the comparability of results from future calibration research? Calibration studies in adults have typically used oxygen consumption as a criterion measure, similar types of source activities, and linear regression to obtain prediction equations that calibrate the activity counts to measured activity intensity levels. However, the methodological diversity of these studies has produced a great deal of variation in the resulting prediction equations and cut points, even when using the same monitor. Thus, data obtained from a relatively robust activity monitoring technology that captures many dynamic physical activities reasonably well have been splintered by the calibration process into a wide range of summary measures that are much less comparable than they could otherwise be. This heterogeneity in calibration results reduces our ability to interpret data obtained from accelerometers between different research groups, across the life span, between populations, and probably between the different monitor types. This report reviews and critiques methods typically used for developing calibration equations and determining activity count cut points for identifying specific intensities of PA among adults, and it highlights the need for flexible research methods that can enhance the comparability of results from future calibration studies.

Supportive parenting, Ecological Context, and Children's Adjustment: A seven-Year Longitudianl Study

Abstract: Two major questions regarding the possible impact of early supportive parenting (SP) on children's school adjustment were addressed:(1) Does SP assessed prekindergarten predict grade 6 adjustment after controlling for early barsh parenting (HP)? (2) Does SP moderate (buffer) the impact of early family adversity on grade 6 adjustment? Parenting and family adversity data were drawn from home-visit interviews with 585 mothers conducted prekindergarten. Four SP measure were derived: mother-to-child warmth, proactive teaching, inductive discipline, and positive involvement. HP was indexed as the use of harsh, physical disciple. Family adversity indicators were socioeconomic disadvantage, family stress, and single parenthood. Children 's adjustment (behavior problems, social skills, and academic performance) in kindergarten and grade 6 was assessedvia teacher ratings and school records. SP predicted adjustment in grade 6, even after controlling for kindergarten adjustment and HP. High levels of SP mitigated the effects of family adversity on later behavior problems. These findings implicate both direct (main effect)and indirect (moderator of adversity) processes in the linkage between positive and supportive aspects of parenting and children's school adjustment.

Business Location Decisions in the United States: Estimates of the Effects of Unionization, Taxes, and Other Characteristics of States

Abstract: This article examines how corporate decisions about the location for a new manufacturing plant in the U.S. are influenced by unionization, taxes, and other characteristics of states. The conditional logit model is used with some modifications to make the model more applicable to the business location decision. The most important finding is that the union sympathies of states have a major effect on business location. The results also indicate that state taxes affect business location, contradicting the conventional wisdom in the economic literature, although the tax effect is of modest magnitude.

A Systematic Review of Early Intensive Intervention for Autism Spectrum Disorders

Abstract: CONTEXT: Early intensive behavioral and developmental interventions for young children with autism spectrum disorders (ASDs) may enhance developmental outcomes. OBJECTIVE: To systematically review evidence regarding such interventions for children aged 12 and younger with ASDs. METHODS: We searched Medline, PsycINFO, and ERIC (Education Resources Information Center) from 2000 to May 2010. Two reviewers independently assessed studies against predetermined inclusion/exclusion criteria. Two reviewers independently extracted data regarding participant and intervention characteristics, assessment techniques, and outcomes and assigned overall quality and strength-of-evidence ratings using predetermined criteria. RESULTS: Thirty-four unique studies met inclusion criteria. Seventeen studies were case series; 2 were randomized controlled trials. We rated 1 study as good quality, 10 as fair quality, and 23 as poor quality. The strength of the evidence overall ranged from insufficient to low. Studies of University of California Los Angeles/Lovaas–based interventions and variants reported clinically significant gains in language and cognitive skills in some children, as did 1 randomized controlled trial of an early intensive developmental intervention approach (the Early Start Denver Model). Specific parent-training approaches yielded gains in short-term language function and some challenging behaviors. Data suggest that subgroups of children displayed more prominent gains across studies, but participant characteristics associated with greater gains are not well understood. CONCLUSIONS: Studies of Lovaas-based approaches and early intensive behavioral intervention variants and the Early Start Denver Model resulted in some improvements in cognitive performance, language skills, and adaptive behavior skills in some young children with ASDs, although the literature is limited by methodologic concerns.

When Bad Things Turn Good and Good Things Turn Bad: Sequences of Redemption and Contamination in Life Narrative and their Relation to Psychosocial Adaptation in Midlife Adults and in Students

Abstract: Midlife adults (age 35 to 65) and college undergraduates provided lengthy, open-ended narrative accounts of personally meaningful episodes from the past, such as life-story high points, low points, turning points, and earliest memories. The oral (adult) and written (student) narratives were coded for redemption and contamination imagery. In the midlife sample, adults scoring high on self-report measures of generativity showed significantly higher levels of redemption and lower levels of contamination sequences. In both samples, redemption sequences in life narrative accounts were positively associated with self-report measures of psychological well-being, whereas contamination sequences predicted low levels of well-being among midlife adults. In addition, redemption sequence scores were a stronger predictor of well-being than were ratings of the overall affective quality of life-narrative accounts. The results are discussed with respect to the empirical literature of benefit-finding in the face of adversi...
