Mothers of children with externalizing behavior problems: cognitive risk factors for abuse potential and discipline style and practices     

McElroy EM  Rodriguez CM 《Child abuse & neglect》2008,32(8):774-784

OBJECTIVE: Utilizing the conceptual framework of the Social Information Processing (SIP) model (Milner, 1993, 2000), associations between cognitive risk factors and child physical abuse risk and maladaptive discipline style and practices were examined in an at-risk population. METHODS: Seventy-three mothers of 5-12-year-old children, who were identified by their therapist as having an externalizing behavior problem, responded to self-report measures pertaining to cognitive risk factors (empathic perspective taking, frustration tolerance, developmental expectations, parenting locus of control), abuse risk, and discipline style and practices. The Child Behavior Checklist (CBCL) provided a confirmation of the child's externalizing behaviors independent of the therapist's assessment. RESULTS: The results of this study suggest several cognitive risk factors significantly predict risk of parental aggression toward children. A parent's ability to empathize and take the perspective of their child, parental locus of control, and parental level of frustration tolerance were significant predictors of abuse potential (accounting for 63% of the variance) and inappropriate discipline practices (accounting for 55% of the variance). CONCLUSIONS: Findings of the present study provide support for processes theorized in the SIP model. Specifically, results underscore the potential role of parents' frustration tolerance, developmental expectations, locus of control, and empathy as predictive of abuse potential and disciplinary style in an at-risk sample.  相似文献   

Independence of the amount and delay ratios in the generalized matching law     

Monica L. Rodriguez  A. W. Logue 《Learning & behavior》1986,14(1):29-37

Eight pigeons chose between pairs of different sizes and delays of reinforcement scheduled according to nonindependent concurrent variable-interval variable-interval schedules. The results were best described by the generalized matching law, where the relative effects of amount and delay on preference are independent and multiplicative. Order of presentation of the conditions had a significant effect on preference that was best represented in the model by a modification of the bias parameter.  相似文献   

‘The rules above the bed’: academic language and learning as hospitality     

Dana Chahal  Juana Maria Rodriguez  Britta Schneider 《高等教育研究与发展》2019,38(5):893-906

ABSTRACT

In times of widening participation, Australian universities trade on notions of diversity, framing themselves as hospitable places of access and inclusion. In this space, Academic Language and Learning (ALL) practitioners may be seen as extending the welcome of the university through practices aimed at addressing students’ diverse needs. These include identifying students ‘at-risk’ of failure and attrition, conducting one-to-one appointments, and embedding academic literacies by team-teaching within disciplines. In this paper, we reflect on these practices through the lens of Derrida’s notion of hospitality, drawing on key themes such as the constitutive power relationships of hospitality, the aporia between conditional and unconditional hospitality, and hospitality as an ethics of difference and openness to the ‘arrival of the new’. For each of the explored practices, we problematise the institutionalised framing of ALL practitioners as hosts in benevolent universities providing an unreserved welcome to the student ‘foreigner’. We examine the practice of identifying students-at-risk and question a conditional hospitality that risks closing the door on the unforeseeable that students may bring. Our reflection on the managerially devalued one-to-one appointments highlights hospitality as ethics, with each appointment presenting a crisis of choice in responsibly welcoming student difference. Team-teaching exposes the ambiguity of the ALL practitioner ‘being at-home’ in embedded contexts while presenting the possibility for disrupting established roles and practices. Engaging with Derrida’s hospitality thus allows us to uncover power dynamics shaping the role of ALL practitioners and offers the possibility of ethical responsiveness to student difference and a radical opening to the new.  相似文献   

Alleged sexual abuse at a day care center: impact on parents     

Dyb G  Holen A  Steinberg AM  Rodriguez N  Pynoos RS 《Child abuse & neglect》2003,27(8):939-950

OBJECTIVE: This report describes the cascade of stressful events and secondary life changes experienced by parents in a case of alleged sexual abuse at a day care program. The study evaluated parents' Posttraumatic Stress Disorder (PTSD) symptoms and general psychological responses to the stressful events 4 years after the alleged abuse, and explored predictive factors of parental distress. METHODS: A total of 39 parents were interviewed about stressful events, life changes, and social support. Current distress reactions, psychological wellbeing, and locus of control were assessed with a battery of standardized measures. RESULTS: Hearing about the sexual abuse, testifying in court, hearing the verdict, and being exposed in media reports were all rated by the parents as distressing events. The majority of the parents experienced secondary life changes after the alleged sexual abuse. Four years after the alleged sexual abuse, one-third of the parents reported a high level of PTSD Intrusive symptoms and one-fourth reported a high level of PTSD Avoidance symptoms. There was a significant positive correlation between a measure of psychological wellbeing and PTSD. Secondary life changes and locus of control significantly predicted PTSD. CONCLUSION: This study demonstrates that the alleged sexual abuse of children in day care and the resulting events in the legal system and the media constitute significant and chronic stressors in the lives of the children's parents. These findings underscore the need to expand the focus of trauma-related sequelae from the child victim to their parents and family.  相似文献

A hybrid system of pedagogical pattern recommendations based on singular value decomposition and variable data attributes     

Carlos Cobos  Orlando Rodriguez  Jarvein Rivera  John Betancourt  Martha Mendoza  Elizabeth León  Enrique Herrera-Viedma 《Information processing & management》2013

To carry out effective teaching/learning processes, lecturers in a variety of educational institutions frequently need support. They therefore resort to advice from more experienced lecturers, to formal training processes such as specializations, master or doctoral degrees, or to self-training. High costs in time and money are invariably involved in the processes of formal training, while self-training and advice each bring their own specific risks (e.g. of following new trends that are not fully evaluated or the risk of applying techniques that are inappropriate in specific contexts).This paper presents a system that allows lecturers to define their best teaching strategies for use in the context of a specific class. The context is defined by: the specific characteristics of the subject being treated, the specific objectives that are expected to be achieved in the classroom session, the profile of the students on the course, the dominant characteristics of the teacher, and the classroom environment for each session, among others. The system presented is the Recommendation System of Pedagogical Patterns (RSPP). To construct the RSPP, an ontology representing the pedagogical patterns and their interaction with the fundamentals of the educational process was defined. A web information system was also defined to record information on courses, students, lecturers, etc.; an option based on a unified hybrid model (for content and collaborative filtering) of recommendations for pedagogical patterns was further added to the system. RSPP features a minable view, a tabular structure that summarizes and organizes the information registered in the rest of the system as well as facilitating the task of recommendation. The data recorded in the minable view is taken to a latent space, where noise is reduced and the essence of the information contained in the structure is distilled. This process makes use of Singular Value Decomposition (SVD), commonly used by information retrieval and recommendation systems. Satisfactory results both in the accuracy of the recommendations and in the use of the general application open the door for further research and expand the role of recommender systems in educational teacher support processes.  相似文献

This study was situated within a year-long, statewide technology integration initiative designed to support technology integration within science, technology, engineering, and math classrooms. It examined the elements used in student artifacts in an attempt to investigate trends in digital artifact creation. Among several conclusions, this examination highlighted areas of significant improvement in student use of technology, such as an increase in the creation of PowerPoint presentations and the inclusion of multimedia elements. The study also highlighted areas for improvement, such as the low cognitive demand for content in the majority of the artifacts.  相似文献   

Are Multiple-choice Items Too Fat?     

Thomas M. Haladyna  Michael C. Rodriguez  Craig Stevens 《教育实用测度》2013,26(4):350-364

ABSTRACT

The evidence is mounting regarding the guidance to employ more three-option multiple-choice items. From theoretical analyses, empirical results, and practical considerations, such items are of equal or higher quality than four- or five-option items, and more items can be administered to improve content coverage. This study looks at 58 tests, including state achievement, college readiness, and credentialing tests. The evidence here supports previous assertions. The article also clarifies distractor functioning criteria and offers a typology of items via distractor functioning.  相似文献   

Toward Effective and Compelling Instruction for High School eCommerce Students: Results from a Small Field Study     

Kenneth J. Luterbach  Diane Rodriguez  Lakecia Love 《TechTrends》2012,56(6):59-63

This paper describes an instructional development effort to create effective and compelling instruction for eCommerce students. Results from a small field study inform the development project. Four high school students in an eCommerce course completed the standalone tutorial developed to teach them how to create a web page in the HyperText Markup Language (HTML). The four participants were also interviewed in an attempt to determine what motivates them to learn. Researcher observations of completed web pages indicated that the tutorial helped the four participants learn introductory HTML tags and, except for one revealing instance, they mastered the content without instructor assistance. Future work to develop an automated system for determining and correcting learner misconceptions evident in dysfunctional hyperlinks would provide additional support to learners. Lastly, this paper discusses implications of the field study results for the design and implementation of effective and compelling instruction.  相似文献   

Numerical study of dc-biased ac-electrokinetic flow over symmetrical electrodes     

Yang Ng W  Ramos A  Cheong Lam Y  Rodriguez I 《Biomicrofluidics》2012,6(1):12817-1281710

This paper presents a numerical study of DC-biased AC-electrokinetic (DC-biased ACEK) flow over a pair of symmetrical electrodes. The flow mechanism is based on a transverse conductivity gradient created through incipient Faradaic reactions occurring at the electrodes when a DC-bias is applied. The DC biased AC electric field acting on this gradient generates a fluid flow in the form of vortexes. To understand more in depth the DC-biased ACEK flow mechanism, a phenomenological model is developed to study the effects of voltage, conductivity ratio, channel width, depth, and aspect ratio on the induced flow characteristics. It was found that flow velocity on the order of mm/s can be produced at higher voltage and conductivity ratio. Such rapid flow velocity is one of the highest reported in microsystems technology using electrokinetics.  相似文献
