Assessing The Cross-Cultural Reliability And Validity Of A Measure Of Parent Satisfaction Among Head Start Caregivers, Anne E. Day Leong
Assessing The Cross-Cultural Reliability And Validity Of A Measure Of Parent Satisfaction Among Head Start Caregivers, Anne E. Day Leong
Journal of Family Strengths
Accurately assessing caregiver satisfaction in their child’s education creates an opportunity for two-sided conversations between caregivers and schools that fosters active family involvement in education. In response to the need for accurate assessment of caregiver satisfaction, Fantuzzo, Perry and Childs (2006) created the Parent Satisfaction in Educational Experiences Scale (PSEE) specifically for low-income caregivers of preschool aged children attending Head Start preschool programs as well as caregivers of kindergarten students. Although the PSEE presents an opportunity to engage caregivers, the measure has not yet been validated on a sufficient sample of men or a sample of caregivers born outside of …

Effects Of Peer Recovery Coaches On Substance Abuse Treatment Engagement Among Child Welfare-Involved Parents, Stephen James, Richard Rivera, Michael S. Shafer
Journal of Family Strengths
There is a limited, but growing body of research on the effectiveness of peer recovery coaches in promoting treatment engagement, retention, and completion among child welfare-involved parents with substance use disorders. A quasi-experimental design was employed using propensity score matching to examine treatment engagement and treatment completion among child welfare-involved substance abusing parents who were exposed to either peer recovery coach engagement services or professional, non-peer engagement services. Using propensity scoring, the comparison sample of parents that did not have peer recovery coaches was statistically matched on the presence of substance exposed newborns, parental use of methamphetamine, and other predictors …

Racial Disproportionality In The Foster Care System In Texas:, Monit Cheung, Patrick Leung
Journal of Family Strengths
This study analyzes the demographic characteristics of foster care children under the conservatorship of the Department of Family and Protective Services (DFPS) in Texas from 2002 to 2013. Using one state as an example, the progress charting data in 12 years demonstrates the need to set up a national agenda on closing the gap in racial disproportionality. While the data reveal an increase of Hispanic children in foster care from 33.6% in 2002 to 41.3% in 2013, in terms of disproportionality, the ratio index for Hispanic children has been much lower (0.83) than that for African American children (2.33) over …

Building Family Strengths Through Successful Parental Involvement Strategies: A Case Study With Latino Immigrant Families And Elementary School Staff, Madison G. Huber-Smith, Anne Williford
Journal of Family Strengths
Latino immigrant families often face significant barriers in becoming involved in their children’s education due to common cultural biases and misunderstandings and language barriers. Moreover, limited evidence suggests that the ways in which Latino immigrant families engage in their children’s education may not be recognized and valued by schools, which operate within mainstream cultural values. As a result, effective outreach and engagement practices specifically for Latino parents, particularly recent immigrants, are not presently well understood. To that end, the purpose of the present case study is to explore and evaluate the strategies used by an elementary school to involve its …
Risk And Protective Factors For The Safety Of Children With Autism: A Qualitative Study Of Caregivers’ Perspectives, Rebecca Pfeffer
Risk And Protective Factors For The Safety Of Children With Autism: A Qualitative Study Of Caregivers’ Perspectives, Rebecca Pfeffer
Journal of Family Strengths
As of 2014, it is estimated that 1 in 68 children born in the United States will be diagnosed with an autism spectrum disorder (ASD). Previous research finds that children with ASDs are victimized at disproportionately high rates compared to their typically-developing peers. Utilizing survey data from a national sample of parents of children with ASDs (n=262) and in-depth semi-structured follow up interviews with a fraction of these participants (n=40), this study indicates that there are potential risk and protective factors in a range of dimensions that may impact the likelihood of victimization among children with autism. Many factors reflected …

Fish Sound Production In The Presence Of Harmful Algal Blooms In The Eastern Gulf Of Mexico, Carrie C. Wall, Chad Lembke, Chuanmin Hu, David A. Mann
Marine Science Faculty Publications
This paper presents the first known research to examine sound production by fishes during harmful algal blooms (HABs). Most fish sound production is species-specific and repetitive, enabling passive acoustic monitoring to identify the distribution and behavior of soniferous species. Autonomous gliders that collect passive acoustic data and environmental data concurrently can be used to establish the oceanographic conditions surrounding sound-producing organisms. Three passive acoustic glider missions were conducted off west-central Florida in October 2011, and September and October 2012. The deployment period for two missions was dictated by the presence of red tide events with the glider path specifically set …

Iggy Azalea isn’t the first artist to profit from a entertainment persona that differs from her “real” personality. But the fact that Azalea is a white woman profiting by employing a fake “black” sound wrought through appropriating is what seems to angers people more than the quality of Azalea’s music, or anything else about her.

The Influence Of Virtual Environment Parameters On Elderly People Standing On One Leg, Tien-Lung Sun
Rehabilitation Practice and Science
Kinect-based exergames enable players to undertake physical exercise in an interactive manner through visual stimulation. Previous studies focused on investigating physical fitness based on calories or heart rate to ascertain the effectiveness of exergames. However, designing an exergame for specific training purposes, with intensity levels suited to the needs and skills of the players, requires the investigation of motion performance to study player experience. This study investigated how the parameters of a Kinect-based exergame combined with balance training exercises influence the balance control of the player and the intensity level that the player can tolerate by analyzing both objective and …

Biomechanical Analysis Of Lower Limb Muscle Power In Elderly Individuals, I-Chung Cheng, Shun-Hwa Wei, Fu-Kong Lieu, Pei-Chen Tsai
Rehabilitation Practice and Science
Background: The aging process may contribute to a decrease in lower extremity function in elderly individuals, which in turn often causes a functional decrease in activities of daily living, loss in quality of life, and increase in risk of accidental falls. In the last few decades, numerous studies in elderly individuals have reported the relation between a high incidence of accidental falls and inadequate muscle strength. Unfortunately, few studies have provided insight about their individual muscle performance, such as the explosive muscle power, from a biomechanical prospective. Quantitative analysis of the sit- to- stand (STS) ability is a useful method …

Rehabilitation Practice and Science
Skeletal muscle cells generate force and produce joint movement and are easily injured. A good understanding of the biological, physiological, and pathological mechanisms of skeletal muscle cells is essential for exploring the regulation of muscle repair, which occurs in the event of an injury. A method for reproducing skeletal muscle cells is essential for studying skeletal muscles. Most studies use cell lines as study models because these are capable of reproducing numerous times. However, the function of cell lines is markedly deviated from that of normal cells. Skeletal muscle cells from primary cell culture more closely represent muscle cells in …

Using the data taken at the Pierre Auger Observatory between December 2004 and December 2012, we have examined the implications of the distributions of depths of atmospheric shower maximum (Xmax), using a hybrid technique, for composition and hadronic interaction models. We do this by fitting the distributions with predictions from a variety of hadronic interaction models for variations in the composition of the primary cosmic rays and examining the quality of the fit. Regardless of what interaction model is assumed, we find that our data are not well described by a mix of protons and iron nuclei over most of …
