Narrowmobilization and Tea Party Activism: A Study of Right-Leaning Alternative Media

Past research concerning the theoretical framework of Resistance Performance (RP) has been based on observations of liberal organizations and activists. In the following essay, we engage in a qualitative content analysis of alternative media utilized by conservative “Tea Party” activists to build on the concept of RP. Overall, we discovered that the dominant theme found in much of the content focuses on “purity,” which is considerably different from past RP research that found broad themes of “human rights,” “democracy,” “be the media,” and “principles of unity” embedded within liberal alternative media content. We conclude that the theme of “purity” gives rise to narrowmobilization, which constructs very focused protest communities within right-leaning politics.     

Interventions supporting baccalaureate achievement of Latinx STEM students matriculating at 2-year institutions: A systematic review

Numerous national reports have identified the importance of significantly improving pathways that begin with Latinx students enrolling in 2-year institutions and ultimately completing baccalaureate degrees in STEM fields at 4-year institutions. Many programs using multiple interventions have been designed, implemented, and studied to achieve this goal. To synthesize what has been learned from studies of these programs, this article presents a systematic review of published studies of programs designed to support Latinx student success in 2-year institutions and successful transfer to 4-year institutions, particularly for STEM majors. A total of 49 quantitative, 9 qualitative, and 16 mixed-methods studies published as reports, articles, or dissertations since 1980 were identified that met the criteria for the review. Studies covered a wide range of interventions, including mentoring, counseling, advising, study groups, tutoring, scholarships, orientations, career services, undergraduate research, articulation agreements, and transfer programs. Individually, these studies report positive influences on student success outcomes, including 2- and 4-year graduation, transfer to a 4-year institution, retention, and success in individual courses. However, the number of qualifying studies was surprisingly small, considering the importance of improving success of Latinx students and the length of time during which the problem has been repeatedly emphasized. Few interventions have been undertaken from explicitly assets-based perspectives or theoretical frameworks. The lack of explicit frameworks underlying interventions—combined with a sole/primary focus on students—suggests many interventions were approached from a deficit-based perspective. Further, the study found no pattern of replication studies that might confirm effectiveness of potentially promising interventions. Based on our analysis of evaluations presented in the studies, it does not appear that the research community has developed agreed-upon methods to evaluate commonly agreed-upon outcomes. Finally, no intervention has been sufficiently supported that widespread implementation could be recommended.     

High-Quality Preschool: The Socioeconomic Composition of Preschool Classrooms and Children's Learning

Research Findings: As policymakers expand access to preschool, the sociodemographic composition of preschool classrooms will become increasingly important. These efforts may create programs that increase the concentration of children from low-income families or, alternatively, foster the creation of socioeconomically diverse preschool classrooms. What effect the creation of such contexts would have on very young children remains unclear. Using multilevel methods and data on 2,966 children in 704 prekindergarten classrooms, this study explores the relationship between socioeconomic classroom composition and children's social and cognitive development. The results indicate positive associations between the mean socioeconomic status (SES) of the class and children's receptive language, expressive language, and mathematics learning, regardless of children's own sociodemographic backgrounds and the characteristics of their classrooms. However, the analyses indicate no association between the development of social competence and class mean SES. Practice or Policy: The links between classroom SES and language and mathematics development were comparable in size to those associated with instructional quality and even children's own SES. Neither structural nor instructional characteristics of prekindergarten classrooms explained these relationships, suggesting the possibility of direct peer effects. The findings indicate that the composition of children's classrooms should be considered an important aspect of preschool quality.     

A mentoring programme based on competency development at a Spanish university: an action research study

This article describes an action research (AR) project for designing and implementing a structured mentoring programme in a Spanish university. A student affairs unit, a team of researchers, faculty-mentors and student-protégés worked together on three cycles of AR. The result is a programmatic mentoring programme for the development of non-technical personal and professional competencies for undergraduate students. This paper describes the original situation that sparked the project, the iterative process followed, the tools and guides developed and the final programme designed. In addition to the increase in the level of satisfaction perceived by the entire university, the paper outlines the five critical factors that emerged from the AR project: the competency development process, programme value added, trust between mentors and protégés, the prominence of the student-protégé in the improvement plans and the continuous improvement culture generated.     

Adaptive progressive download based on the MPEG-4 file format

In this paper we describe how progressive download and adaptive streaming can be combined into a simple and efficient streaming framework. Based on the MPEG-4 file format (MP4) we use HTTP for transport and argue that these two components are sufficient for specifying an open streaming architecture. The client selects appropriate chunks from the MP4 file to be transferred based on (1) the header information (i.e. the “moov” box) in the first part of the file and (2) his observation of network throughput. The framework is completely client driven which allows for better server scalability and reduces signalling overhead. We discuss architecture and implementation issues such as complexity, interoperability and scalability and compare to 3GPP PSS Rel-6 adaptive streaming when appropriate. Measurements from a simple MP4/HTTP streaming client are presented showing that appropriate chunks are selected such that increased reliability is achieved.     

Preschool Children's Social Interactions Involving Moral and Prudential Transgressions: An Observational Study

Preschool children's social interactions with teachers and peers were observed in the context of moral and prudential events. Twenty groups of children were observed during free play for a total of 164 hours (8 hours per each group). Four types of moral transgressions were observed: physical harm, psychological harm, property loss, and property damage. The majority of the moral transgressions pertained to physical harm and property loss. There were equal frequencies of both moral and prudential physical harm acts; Moral physical harm acts resulted in actual harm; whereas, prudential acts were only potentially harmful. Teachers responded differently to moral and prudential rule violations. Gender differences were noted with regard to instigator, victim teachers' responses, and victims' responses.

Politics and Interests in the Republic of Science

The institutions of science arecomposed of communities with conflicting andoverlapping interests. In the United States,the internal governance of science resemblesthe structure of republican government,particularly in its fragmentation,representation, and extension. This articlecalls upon Michael Polanyi's metaphor of a`Republic of Science' in the context ofAmerican history and political theory, toexamine the ways in which these interests arerepresented. Using the metaphor obliges us toask about rules of citizenship in the`Republic', and to determine whether those whopay for science should also be represented inits institutions.
