The decisions and processes involved in a systematic search strategy: a hierarchical framework

Objective:The decisions and processes that may compose a systematic search strategy have not been formally identified and categorized. This study aimed to (1) identify all decisions that could be made and processes that could be used in a systematic search strategy and (2) create a hierarchical framework of those decisions and processes.Methods:The literature was searched for documents or guides on conducting a literature search for a systematic review or other evidence synthesis. The decisions or processes for locating studies were extracted from eligible documents and categorized into a structured hierarchical framework. Feedback from experts was sought to revise the framework. The framework was revised iteratively and tested using recently published literature on systematic searching.Results:Guidance documents were identified from expert organizations and a search of the literature and Internet. Data were extracted from 74 eligible documents to form the initial framework. The framework was revised based on feedback from 9 search experts and further review and testing by the authors. The hierarchical framework consists of 119 decisions or processes sorted into 17 categories and arranged under 5 topics. These topics are “Skill of the searcher,” “Selecting information to identify,” “Searching the literature electronically,” “Other ways to identify studies,” and “Updating the systematic review.”Conclusions:The work identifies and classifies the decisions and processes used in systematic searching. Future work can now focus on assessing and prioritizing research on the best methods for successfully identifying all eligible studies for a systematic review.     

Behavioral variability is controlled by discriminative stimuli

Previous research has demonstrated that behavioral variability can be modified by reinforcers contingent on it, but there has been no convincing evidence of discriminative stimulus control over such variability. We therefore rewarded 20 rats for variable response sequences in the presence of one stimulus and provided equal rewards independently of sequence variability in the presence of a second stimulus. We found that sequence variability was significantly higher during the first stimulus than during the second, with the greatest difference occurring immediately following onset of the stimuli. Removing the discriminative stimuli caused levels of variability to converge. These experiments provide strong evidence that behavioral variability can be controlled by discriminative stimuli, which may be important for general theories of operant behavior and their applications.     

School-based bullying experiences as reflected by adults with visual impairments

The purpose of this study was to describe the reflections of adults with visual impairments regarding bullying experiences during their school-based education. An interpretative phenomenological analysis research approach was used and 11 participants (aged 20–35 years; seven women, four men) participated in this study. The sources of data were semi-structured audiotaped telephone interviews and reflective field notes. Thematic development was undertaken utilizing a three-step analytical process guided by the research approach. Based on the data analysis, three interrelated themes were constructed: (a) “It would be when they knew there weren't teachers watching”: bullying experiences in unowned and unstructured spaces; (b) “Going through the motions”: feelings about verbal, social, and physical victimization; and (c) “They had their own insecurities”: understanding the bullies and bystanders. The emerged themes provide a unique insight into the way in which those with visual impairments experienced bullying in schools and the meaning they ascribed to those experiences.     

Connecting brawn,brains, and people: an exploration of non-traditional outcomes of youth stewardship programs

Programs in which youth work collectively on an environmental stewardship project may provide social learning opportunities that support social-ecological system resilience and the development of social ties. However, few empirical investigations document the social learning processes that actually occur in these programs. This paper presents a multi-case study ethnography of six summer youth civic ecology education programs. Methods included participant observation, interviews, and group mind-mapping. The results suggest that programs offered moderate social learning contexts, with participants having little say over the direction and design of the program’s environmental stewardship goals. Nevertheless, participants worked together and collaborated on projects led by program leaders, with whom they developed strong ties. In programs focused on a single issue in one place, participants shifted their conceptual frames to include locally relevant concepts. While participants did not form strong ties with other program participants or with individuals from outside programs, they valued experiences where they led volunteers or were observed by others doing stewardship work. These results suggest that environmental stewardship programs can be designed to enhance social learning opportunities, which could incorporate strategies to increase youth developing ties with each other and with outside organizations.     

The effect of practical work on students' understanding of combustion

This paper describes a study which investigated 14 and 15 year old students' understanding of combustion in both England and Spain, and explores the effect of practical laboratory experience on students' understanding. The teaching and learning styles used with the students in the study were explored using questionnaires and interviews. The students' understanding of combustion was explored using a questionnaire. The responses of English and Spanish students are significantly different. The quality of the responses is explored in terms of the awareness of students of the involvement of gases in combustion, and it appears, however, that the more extensive use of practical work in English schools has had only a marginal effect on their understanding of combustion.     

How vocational psychologists can make a difference in K–12 education

In general, vocational psychologists have not been engaged in applied research that demonstrates how career interventions can improve educational problems that matter to relevant decision-makers and stakeholders. This article describes how vocational psychology can make a difference in K–12 education by embracing an interdisciplinary community-based approach. To illustrate this approach, a quasi-experimental evaluation of multiple after-school programs provided to a sample of Hispanic Americans is presented. This study offers a realistic example of how researchers in the field can induce change through the development of meaningful partnerships within the community.     

Barriers and facilitators of physical education participation for students with disabilities: an exploratory study

The purpose of this study was to explore the barriers and facilitators to participation in physical education (PE) for students with disabilities (SWD) from the perspectives of in-service physical educators. A convenience sample of 168 physical educators (72% female, 94% Caucasian) from the United States completed a short questionnaire. After data collection was completed, data were compiled into a spreadsheet and the first and third authors independently open-coded the responses. Cohen’s κ was computed to determine the inter-rater agreement on the open-coding process of the teacher responses. In total, 741 facilitators and 652 barriers were identified, and the most commonly reported barriers and facilitators centered on either teacher- or program-related responses. Barrier and facilitator categories were positively correlated (φ?=?.42 and Cramer’s ν?=?.16, p?=?.00); however, neither years of teaching experiences (r_barriers?=?.01, p?=?.89; r_facilitators?=?.05, p?=?.45) nor frequency of teaching SWD (τ_barriers?=?.05, p?=?.49; τ_facilitators?=?.05, p?=?.47) was significantly associated with the number of barriers or facilitators reported. Unique to other research in this arena, teachers frequently reported that personal-related variables were also as barriers to PE participation.
