Variance Estimation Using Replication Methods in Structural Equation Modeling With Complex Sample Data     

Laura M. Stapleton 《Structural equation modeling》2013,20(2):183-210

This article discusses replication sampling variance estimation techniques that are often applied in analyses using data from complex sampling designs: jackknife repeated replication, balanced repeated replication, and bootstrapping. These techniques are used with traditional analyses such as regression, but are currently not used with structural equation modeling (SEM) analyses. This article provides an extension of these methods to SEM analyses, including a proposed adjustment to the likelihood ratio test, and presents the results from a simulation study suggesting replication estimates are robust. Finally, a demonstration of the application of these methods using data from the Early Childhood Longitudinal Study is included. Secondary analysts can undertake these more robust methods of sampling variance estimation if they have access to certain SEM software packages and data management packages such as SAS, as shown in the article.  相似文献   

Explaining Method Effects Associated With Negatively Worded Items in Trait and State Global and Domain-Specific Self-Esteem Scales     

José M. Tomás  Amparo Oliver  Laura Galiana  Patricia Sancho  Marisol Lila 《Structural equation modeling》2013,20(2):299-313

Several investigators have interpreted method effects associated with negatively worded items in a substantive way. This research extends those studies in different ways: (a) it establishes the presence of methods effects in further populations and particular scales, and (b) it examines the possible relations between a method factor associated with negatively worded items and several covariates. Two samples were assessed: 592 high school students from Valencia (Spain), and 285 batterers from the same city. The self-esteem scales used were Rosenberg's Self-Esteem Scale, the State Self-Esteem Scale, and Self-Esteem 17. Anxiety was also assessed with the State-Trait Anxiety Inventory, and gender and educational level were taken into account. The models were conducted using a multiple indicators and multiple causes (MIMIC) model framework. The evidence in this research pointed out that method effects were present across the different measures of self-esteem. Moreover, a significant and negative effect of anxiety on method effects was present across scales and samples, whereas no effects of age or educational level where found.  相似文献   

The Role of Set for Variability in Irregular Word Reading: Word and Child Predictors in Typically Developing Readers and Students At-Risk for Reading Disabilities

ABSTRACT

In a quasiregular orthography like English, children inevitably encounter irregular words during reading. Previous research suggests successful reading of an irregular word depends at least partially on a child’s ability to address the mismatch between decoded form and stored word pronunciation, referred to as a child’s set for variability, and the word’s relative transparency, measured here using a spelling to pronunciation transparency rating. Item-level analyses were used to explore the relationship between general child performance on the set for variability mispronunciation task, word specific set for variability (predicting reading of that word), spelling to pronunciation transparency rating, and irregular word reading. Significant predictors included general word reading, general set for variability performance, and item-specific set for variability performance; word frequency and spelling to pronunciation transparency rating; and an interaction between word reading and the transparency rating. Results underscore the importance of considering both general and item-specific factors affecting irregular word reading.  相似文献   

Teachers' Emotional Support Consistency Predicts Children's Achievement Gains and Social Skills     

Timothy W. Curby  Laura L. Brock  Bridget K. Hamre 《Early education and development》2013,24(3):292-309

Research Findings: It is widely acknowledged that consistent, high-quality teacher–student interactions promote optimal developmental outcomes for children. Previous research on the quality of teacher–student interactions provides empirical support for this premise. Little research has been conducted on the consistency of teacher–student interactions. This study examines whether consistency in teachers' emotional support is related to better academic and social outcomes for children. Multiple observations were conducted in 694 prekindergarten classrooms. Mean levels of emotional support and consistency of emotional support were used as predictors in multilevel models. Results indicated that when mean levels of emotional support were controlled, within-day consistency of emotional support predicted several academic outcomes in prekindergarten as well as social competence in kindergarten. Practice or Policy: Results indicate that teachers' consistency of emotional support is a salient aspect of children's classroom environment. Findings suggest that consistency should be considered when evaluating teachers' emotionally supportive interactions.  相似文献   

Children's Preliteracy Skills: Influence of Mothers' Education and Beliefs About Shared-Reading Interactions     

Stephanie M. Curenton  Laura M. Justice 《Early education and development》2013,24(2):261-283

Research Findings: This research investigated the associations among children's preliteracy skills, mothers' education, and mothers' beliefs about shared-reading interactions for 45 Appalachian families. These variables were studied for lower income, primarily European American, families residing in a geographically isolated, small, rural community in the Appalachian Mountains. Children's performance on standardized measures of preliteracy skills pertaining to print concepts and alphabet knowledge was substantially lower than normative references, but their performance on tasks assessing their understanding of environmental print was similar to normative references. The preliteracy skills of children with more educated mothers were significantly better than those of children with less educated mothers. More educated mothers had higher ratings on a measure of parental beliefs about shared reading than less educated mothers had; however, maternal reports of the frequency of home literacy practices were similar for both groups. Mediation analyses indicated that mothers' beliefs about shared-reading interactions served as a mediator for the association between maternal education and children's understanding of reading conventions. Practice or Policy: Future directions for research and implications for practice are discussed.  相似文献   

Assistant Teachers in Prekindergarten Programs: What Roles Do Lead Teachers Feel Assistants Play in Classroom Management and Teaching?     

Laura Stout Sosinsky  Walter S. Gilliam 《Early education and development》2013,24(4):676-706

Assistant teachers are a ubiquitous yet virtually overlooked part of the early education workforce. Assistant teacher education level and its relationship to various classroom characteristics and the roles lead teachers feel assistants play in classroom management and teaching were examined in a nationally representative sample of 3,191 state-funded prekindergarten classes. Research Findings: Most classrooms had at least 1 paid assistant teacher, and classrooms with multiple assistants were more likely to be in Head Start. Lead teachers in public schools were more likely to have a bachelor's degree or higher, to be paired with an assistant with a high school degree, and to report fewer release hours for planning (alone or shared with assistants) than teachers in Head Start. Hierarchical multiple regression indicated that assistant teachers were rated as most useful to teaching duties when the classroom was in a Head Start setting, when the discrepancy between the lead and assistant teachers’ education was smaller, and when there were more shared release hours for planning. Practice and Policy: Implications focus on future prekindergarten teacher workforce needs, the need for more shared planning time and guidance in its use, and the need for more attention to and support for the training and roles of assistant teachers.  相似文献   

Sensemaking and social processes in digital government projects     

Luis Felipe Luna-Reyes  David F. Andersen  Laura J. Black  Theresa A. Pardo 《Government Information Quarterly》2021,38(2):101570

This research identifies main feedback dynamics associated with social processes necessary to make sense of ambiguous project goals, typical of large digital government projects. The study reports on findings from a case analysis using participatory approaches in system dynamics, based on a digital government project integrating information systems of New York's criminal justice agencies. Findings stress the importance of visuals in the sensemaking process that results from the interaction of technical and social outcomes produced through identifying and continuously re-interpreting main project issues and goals. Project analyses suggest that requisite elements of successfully managing this type of project include 1) facilitation that enables diversity of ideas, 2) shared visuals and re-presentations of participants' efforts to work on the issues, and 3) iterative social construction of objectives, progress, and valid processes for doing the work; each of these plays a role in three different feedback processes sustaining (or undermining) the group engagement needed to yield successful integrative work. The study contributes to the literature in digital government by introducing the lenses of people-centered project management processes, an emerging approach in project management, to underscore the role of social processes in technical projects.  相似文献

No Such Thing as a Baby: Responses to Infant Cry Paradigms Are Primarily Influenced by Parents’ Experiences and Behavior     

Laura M. River  Jessica L. Borelli 《Parenting, science and practice》2019,19(1-2):173-176

SYNOPSIS

This article builds on our previous work demonstrating that, when exposed to work–family conflict, parents with high levels of attachment anxiety exhibit greater work–family guilt and less tolerance of infant distress. We respond to commentaries suggesting that the theoretical model could be enhanced by better accounting for innate infant differences and parent psychopathology, arguing that it is possible that parents’ experiences of work–family conflict and attachment anxiety precede the development of psychopathology and may influence the development of infant temperament and behavior. We further explore clinical implications of our findings and identify key suggestions for future work, with an emphasis on the roles of parental experiences of childhood maltreatment and insensitive caregiving.  相似文献   

Analytical attractions and the techno-continuum: Conceptualising data obsessions and consequences in elite sport     

Geoffery Z. Kohe  Laura G. Purdy 《Sport, Education and Society》2019,24(7):742-755

The proliferation of sports science and technological innovation within performance settings has precipitated the generation of increasing volumes of data to aid athletes. Copious data production has also perpetuated the privileging of scientific information, and a ‘thirst’ for ‘more data’ as an unproblematic ‘truth’. Of significance is not merely the use of technology for the production of data-for-data's sake, or the utility of data for a greater cause (e.g. the good of the team), but the quest for personalised data for individual athletes to be analysed, and reflected upon ad nauseam. Furthering scholarship on disciplining bodies, we argue that increased technological consumption, and the related excessive quantification of athletes’ bodies via data production, adds further insecurity into performance sports work. Finally, attention is given to the cultural step-change new techno-dispositions may now present.  相似文献
