Supporting child welfare (CW) workers’ ability to accurately assess substance abuse needs and link families to appropriate services is critical given the high prevalence of parental substance use disorders (SUD) among CW-involved cases. Several barriers hinder this process, including CW workers’ lack of expertise for identifying SUD needs and scarcity of treatment resources. Drawing from theories and emergent literature on interagency collaboration, this study examined the role of collaboration in increasing the availability of resources for identifying and treating SUDs in CW agencies. Using data from the second cohort of families from the National Survey of Child and Adolescent Well-Being, study findings highlight a lack of SUD resources available to CW workers. On the other hand, the availability of SUD resources was increased when CW agencies had a memorandum of understanding, co-location of staff, and more intense collaboration with drug and alcohol service (DAS) providers. These results provide evidence to support efforts to improve collaboration between CW and DAS providers and showcase specific collaboration strategies to implement in order to improve service delivery.  相似文献

Variables that address student enrollment patterns (e.g., persistence, enrollment inconsistency, completed credit hours, course credit load, course completion rate, procrastination) constitute a longstanding fixture of analytical strategies in educational research, particularly research that focuses on explaining variation in academic outcomes. However, nearly all measures of enrollment patterns are handicapped by untested assumptions about a more fundamental measure, namely students’ rate of progress. In this paper, I first explain how a variety of widely used measures of enrollment patterns are inextricably linked to students’ rate of progress. I then describe a method of modeling mathematically students’ rate of progress that employs hierarchical (multilevel) discrete-time event history analysis of repeated events. I conclude with an empirical example of the application of this method in which I test several hypotheses concerning students’ rate of progress through the remedial math sequence toward the outcome of college-level math competency. In addition to the utility of the method that is proposed here, the issues discussed in this paper have important practical implications for institutional research, particularly with respect to the use of the various measures of enrollment patterns to explain variation in students’ attainment.

Increasing recognition of the constructivist nature of learning as well as the diversity of student learning styles highlights the need for teachers to use different teaching styles. Unfortunately, little is known about teachers’ use and perception of various teaching styles. The purpose of this study was to explore physical education teachers’ self-reported use and perceptions of various teaching styles. Participants were 212 physical education teachers representing a variety of elementary and secondary school settings. Teachers had significantly different experiences in the use and perceptions of the different teaching styles. Their perceptions also differed according to self-rated teaching ability related to using the styles.  相似文献

Analyzing interdisciplinarity: Typology and indicators   总被引:1,自引:0,他引:1  
Both funding agencies and scholars in science studies have become increasingly concerned with how to define and identify interdisciplinarity in research. The task is tricky, since the complexity of interdisciplinary research defies a single definition. Our study tackles this challenge by demonstrating a new typology and qualitative indicators for analyzing interdisciplinarity in research documents. The proposed conceptual framework attempts to fulfill the need for a robust and nuanced approach that is grounded in deeper knowledge of interdisciplinarity. As an example of using the framework, we discuss our empirical investigation of research proposals funded by a national funding agency in Finland.  相似文献

Communication and information processes are vital in any company. The use of lean manufacturing concepts applied to the communication and information process aims to reduce waste and make the flows leaner and simpler. Lean information is a new strand of lean concepts and applications. The purpose of this study was to analyze quantitatively the publications concerning the subject, outlining an overview for the new research field of lean communication. Aiming for a deeper understanding, the concepts of lean information were applied in a real process. The quantitative analysis was carried out to find the main authors and works, as well as the main terms used in related works. We used the methods of citations works, co-citation references, and co-occurrence of words using the VOSviewer software. This software was primarily designed to analyze bibliometric networks in order to create, visualize, and assess maps based on network data generated from queries in journals. We found a lack of a methodology for the development and implementation of lean information concepts. We observed a gap which had not been addressed yet, that is, mapping communication flows and developing and implementing lean information. Moreover, there was no method for improvement, implementation, and control.  相似文献

This paper discusses three related examples of mission-oriented agricultural institutional innovations associated with substantial crop yield increases in the 20th century. It begins with the implementation of the United States Land-Grant System and then discusses in turn the planning and implementation of the two grand missions that led successively to the yield increases in wheat and rice that heralded the onset of the “Green Revolution.” It notes the remarkable role of the Rockefeller Foundation in identifying these two missions, and selecting personnel developed within the land-grant system to execute them with remarkable effectiveness.  相似文献
