Creating search strategies for systematic reviews, finding the best balance between sensitivity and specificity, and translating search strategies between databases is challenging. Several methods describe standards for systematic search strategies, but a consistent approach for creating an exhaustive search strategy has not yet been fully described in enough detail to be fully replicable. The authors have established a method that describes step by step the process of developing a systematic search strategy as needed in the systematic review. This method describes how single-line search strategies can be prepared in a text document by typing search syntax (such as field codes, parentheses, and Boolean operators) before copying and pasting search terms (keywords and free-text synonyms) that are found in the thesaurus. To help ensure term completeness, we developed a novel optimization technique that is mainly based on comparing the results retrieved by thesaurus terms with those retrieved by the free-text search words to identify potentially relevant candidate search terms. Macros in Microsoft Word have been developed to convert syntaxes between databases and interfaces almost automatically. This method helps information specialists in developing librarian-mediated searches for systematic reviews as well as medical and health care practitioners who are searching for evidence to answer clinical questions. The described method can be used to create complex and comprehensive search strategies for different databases and interfaces, such as those that are needed when searching for relevant references for systematic reviews, and will assist both information specialists and practitioners when they are searching the biomedical literature.

Algorithmic Techniques

We describe and evaluate the algorithmic techniques that are used in the FF planning system. Like the HSP system, FF relies on forward state space search, using a heuristic that estimates goal distances by ignoring delete lists. Unlike HSP's heuristic, our method does not assume facts to be independent. We introduce a novel search strategy that combines hill-climbing with systematic search, and we show how other powerful heuristic information can be extracted and used to prune the search space. FF was the most successful automatic planner at the recent AIPS-2000 planning competition. We review the results of the competition, give data for other benchmark domains, and investigate the reasons for the runtime performance of FF compared to HSP.

The Family

Abstract Background The Canadian prevalence of Autism Spectrum Disorder (ASD) is one in 66 children affecting many families nationwide. Increasingly, clinicians are tasked with discussing new ASD diagnoses with families; however, many physicians are not comfortable with the conversation, despite self-reported familiarity with ASD. Concurrently, research indicates that families are often dissatisfied with their diagnostic journey, including the diagnostic conversation, which has been described as “profound to almost all parents” (Abbott et al., 2012). Given the importance of this moment, we applied a qualitative meta-synthesis design to gain a deeper understanding of the family experience. Meta-synthesis is an emerging field in health sciences, wherein a systematic search strategy is coupled with qualitative analysis. It is valuable for evidence-driven practices and policies as large volumes of qualitative literature are synthesized into actionable concepts. Objectives We aim to describe and appreciate the family experience of an ASD diagnostic conference. We define the diagnostic conference as is the meeting where children, parents, and/or families are told that the child has an ASD diagnosis. Design/Methods We conducted a systematic search to capture relevant qualitative studies, including all qualitative approaches and qualitative components of mixed-methods studies. A search strategy was developed by a medical librarian with systematic review expertise. An initial search of three databases was undertaken to identify keywords. These terms were then used in searching a wider array of pertinent databases. The search was not limited by dates. Applying Saini and Shlonsky’s (2012) meta-synthesis method, included studies’ demographic and contextual data will be extracted. “Findings/Results” sections of included articles will also be extracted and coded by two independent reviewers. Codes will be translated into themes by an interdisciplinary team of two to five reviewers applying an inductive and iterative process, with a critical disability theoretical lens. Themes will be integrated to form an overall synthesis of the family experience of the ASD diagnostic conference. Results In total, 1329 titles/abstracts were reviewed: 23 were selected for inclusion and 24 are pending team discussion. Preliminary analysis reflects shared concepts among included articles such as: provider-family rapport; conflict over who is the expert; comprehensiveness; language; body language; individuals present; physical space; elements of ASD emphasized (positive vs. negative); hope. Most studies were based in North America or Europe with Caucasian participants represented. Mothers were relatively over-represented as participants. In applying a critical disability theoretical lens, initial observations of the language of included studies present a negative framework for meaning making of an ASD diagnosis. Conclusion This meta-synthesis will provide an in-depth appreciation of the family experience of the ASD diagnostic conference and explore the context of published research. In doing so, it may inform individual clinician practices, medical education around communication, and family-centered-care policies.

Job Aid

Previous research in inspection has shown that a systematic search strategy is more effective than a random search strategy in looking for defects. Moreover, past studies have shown that training can improve search strategy. The purpose of this study was to determine if a job aid could be used to train inspectors to adopt a systematic search strategy and thereby improve their search performance. The study used a computer simulated inspection task and a job aid, which included a cursor that traced a systematic search pattern over the inspection surface represented by the screen. An experiment was designed wherein sixteen subjects were randomly assigned to two groups, those who received practice and instructions on the use of a systematic search strategy and those who received training on the job aid. The results are analyzed and reported

This systematic review examines whether the use of children’s literature in EFL classrooms supports the 4Cs of CLIL—content, communication, cognition, and culture. Previous research has shown many benefits for using children’s literature in English-dominant classroom settings, but it seems little attention has been given to its use in EFL contexts and no attention in CLIL. This study utilizes a systematic search strategy to collect and synthesize current research on children’s literature use in EFL settings in order to better understand how children’s literature may impact EFL student learning and, specifically, examine whether its use can meet the 4Cs of CLIL. Records from four databases were screened for studies using children’s literature in EFL settings, resulting in the inclusion of 15 articles. The analysis of the articles reveals that current research shows evidence that the use of children’s literature can help facilitate student learning in content, communication, cognition, and culture. However, despite this clear connection to the goals of CLIL, investigations on children’s literature remain absent from CLIL research. We believe this research lends support for the use of children’s literature in the CLIL classroom and calls for more attention, both by practitioners and researchers, toward the use of children’s literature in CLIL classrooms.

A dominant component of quality control, visual inspection can be broken down into two elements: visual search and decision-making. This study focuses on the search process. The search process has been mathematically described as random, systematic, or somewhere in between. Mathematical models and empirical studies have shown that the best performance in detecting defects during visual inspection results from the use of a systematic search strategy. For this study, a job aid that could potentially be used as an off-line training tool was developed to promote systematic visual search strategy. The job aid, a moving cursor on the viewing screen, was used to determine an optimal search speed or a range of optimal speeds for which the highest inspection accuracy could be achieved.
