Tests of Equivalence for One-Way Independent Groups Designs     

Robert A. Cribbie  Chantal A. Arpin-Cribbie  Jamie A. Gruman 《Journal of Experimental Education》2013,81(1):1-13

Researchers in education are often interested in determining whether independent groups are equivalent on a specific outcome. Equivalence tests for 2 independent populations have been widely discussed, whereas testing for equivalence with more than 2 independent groups has received little attention. The authors discuss alternatives for testing the equivalence of more than 2 independent populations, and they use a Monte Carlo study to demonstrate and compare the performance of these alternatives under several conditions. The results indicate that a 1-way test (e.g., Wellek's F test) is recommended for assessing the equivalence of more than 2 independent groups because approaches based on conducting pairwise tests of equivalence are overly conservative.  相似文献   

Early Neglect Is Associated With Alterations in White Matter Integrity and Cognitive Functioning

Cognitive deficits have been reported in children who experienced early neglect, especially children raised in institutionalized settings. Previous research suggests that early neglect may differentially affect the directional organization of white matter in the prefrontal cortex (PFC). This may be one mechanism to explain cognitive deficits associated with neglect. To test this idea, properties of white matter and neurocognitive performance were assessed in children who suffered early neglect and those raised in typical environments (n = 63, M_age = 11.75 years). As predicted, prefrontal white matter microstructure was affected, consistent with more diffuse organization, in children that suffered early neglect and this was related to neurocognitive deficits. Such findings underscore how early adversity may affect the PFC and explain cognitive deficits associated with neglect.  相似文献   

An Empowerment Approach for Elders Living With Diabetes: A Pilot Study of a Community-Based Self-Help Group—The Diabetes Club     

Vaughn A. DeCoster  Lori George 《Educational gerontology》2013,39(9):699-713

ABSTRACT

Diabetes mellitus is a disabling, deadly disease, affecting one in five of adults over 65. Unfortunately, for the few elders that receive diabetes self-care training it is often taught using traditional didactic methods that are insensitive to their unique needs and immersed in the traditional medical paradigm. Integrating diabetes self-care into daily living demands more than knowledge acquisition and skill mastery; it requires acceptance of the disease, motivation for change, instrumental and emotional support, general problem-solving skills, and control over one's life – empowerment. This project sought to develop and pilot-test a peer-led, community-based, self-help intervention for elders with diabetes—the Diabetes Club. The intervention targeted diabetes self-efficacy, seeking to empower elders then increase diabetes self-care behavior targets, resulting in improved glycemic control. Club members and social workers collectively developed, implemented, tested intervention protocols, detailed in this paper with additional materials available on a dedicated website. Albeit over a short time period, findings showed significant improvements in diabetes self-efficacy, self-care behaviors, and reduction of glycosolated hemoglobin (A1C). The results are promising, demonstrating the benefits of social-work involvement in diabetes and the potential of elders helping themselves and each other.  相似文献   

Factors Contributing to Readmission of Seniors into Acute Care Hospitals     

Vaughn DeCoster  Katie Ehlman  Carolyn Conners 《Educational gerontology》2013,39(12):878-887

Medicare spending is expected to increase by 79% between the years 2010 and 2020, caused, in-part, by hospital readmissions within 30 days of discharge. This study identified factors contributing to hospital readmissions in a midwest heath service area (HSA), using Coleman's Transition Care Model as the theoretical framework. The researchers analyzed data from the Centers for Medicaid and Medicare Services and findings from a survey of seniors and a focus group of health professionals. The targeted HSA had a lower overall readmission rate than the national average, yet higher for surgical discharges in particular. Analysis of survey and focus data showed that factors centered around the area of patient-provider and provider-provider communication processes, patient adherence, and health literacy. The study's convenience sample limits its generalizability. However, findings are consistent with the theoretical framework and past research, demonstrating that the solution to the rising health care costs may be less high tech or pharmaceutical interventions per se but more fundamental communication among providers as well as with patients and caregivers.  相似文献   

A Longitudinal Study of Forms and Functions of Aggressive Behavior in Early Childhood     

Dianna Murray-Close  Jamie M. Ostrov 《Child development》2009,80(3):828-842

The purpose of this study was to investigate the distinct forms (i.e., physical and relational) and functions (i.e., proactive and reactive) of aggressive behavior during early childhood ( n  =   101; M age = 45.09 months). Forms, but not functions, of aggressive behavior were stable over time. A number of contributors to aggression were associated with distinct subtypes of aggressive behavior. Females and socially dominant children were more relationally aggressive and older children were less physically aggressive than their peers. Longitudinal analyses indicated that social dominance predicted decreases in physical aggression and peer exclusion predicted increases in relational aggression. Overall, the results provide support for the distinction between subtypes of aggression in early childhood.  相似文献   

Differences in step characteristics and linear kinematics between rugby players and sprinters during initial sprint acceleration     

James J. Wild  Ian N. Bezodis  Jamie S. North  Neil E. Bezodis 《European Journal of Sport Science》2018,18(10):1327-1337

The initial steps of a sprint are important in team sports, such as rugby, where there is an inherent requirement to maximally accelerate over short distances. Current understanding of sprint acceleration technique is primarily based on data from track and field sprinters, although whether this information is transferable to athletes such as rugby players is unclear, due to differing ecological constraints. Sagittal plane video data were collected (240?Hz) and manually digitised to calculate the kinematics of professional rugby forwards (n?=?15) and backs (n?=?15), and sprinters (n?=?18; 100?m personal best range?=?9.96–11.33?s) during the first three steps of three maximal sprint accelerations. Using a between-group research design, differences between groups were determined using magnitude-based inferences, and within-group relationships between technique variables and initial sprint acceleration performance were established using correlation. Substantial between-group differences were observed in multiple variables. Only one variable, toe-off distance, differed between groups (d?=??0.42 to ?2.62) and also demonstrated meaningful relationships with sprint performance within all three groups (r?=??0.44 to ?0.58), whereby a stance foot position more posterior relative to the centre of mass at toe-off was associated with better sprint performance. While toe-off distance appears to be an important technical feature for sprint acceleration performance in both sprinters and rugby players, caution should be applied to the direct transfer of other kinematic information from sprinters to inform the technical development of acceleration in team sports athletes.  相似文献

Learning from inquiry‐based laboratories in nonmajor biology: An interpretive study of the relationships among inquiry experience,epistemologies, and conceptual growth     

Carolyn S. Wallace  Mai Yin Tsoi  Jamie Calkin  Marshall Darley 《科学教学研究杂志》2003,40(10):986-1024

The use of inquiry‐based laboratory in college science classes is on the rise. This study investigated how five nonmajor biology students learned from an inquiry‐based laboratory experience. Using interpretive data analysis, the five students' conceptual ecologies, learning beliefs, and science epistemologies were explored. Findings indicated that students with constructivist learning beliefs tended to add more meaningful conceptual understandings during inquiry labs than students with positivist learning beliefs. All students improved their understanding of experiment in biology. Implications for the teaching of biology labs are discussed. © 2003 Wiley Periodicals, Inc. J Res Sci Teach 40: 986–1024, 2003  相似文献
