Media multitasking has been receiving increased attention from communication scholars as well as scholar in other fields, with studies focusing on the prevalence, predictors, behavior, and effects. Several recent papers have provided overviews of findings from media multitasking research, or provided frameworks to help researchers think about conceptual issues around multitasking. This article expands on those efforts by refining the methodological elements that are important to consider in media multitasking research. We discuss the validity of operationalizations in previous studies, and the impact that design and measures had on the conclusions drawn. In order to do this, we map the different options for manipulating and measuring media multitasking, discuss the implications, and provide guidelines for future research examining media multitasking to help connect disparate findings and provide additional guidance for researchers to move forward with this topic. 相似文献

This study expands conceptions of organizational membership by examining individuals whose relationships with their organizations are traditionally characterized as involuntary in nature. Data from inmates and prison employees in four U.S. and Norwegian correctional institutions was examined using structuration theory as an emergent interpretive lens, and five primary ways in which involuntary membership is constructed in communication are identified: physical environment, mobility, relationships, engagement, and body. These facets are presented as the foundation of a continuum-based theoretical perspective on (in)voluntary membership and are discussed for their applicability to future research and theorizing across organizational communication studies. 相似文献

Purpose: To evaluate the reliability and validity of the six-minute walk test (6MWT) with respect to its ability to predict functional capacity in patients with chronic heart failure. Methods: A systematic review was performed via 8 databases to assess relevant English language full-text articles published from January 1, 1980 to October 31, 2009. Participant characteristics, interventions, reliability, validity, and predictive value for each article with respect to functional capacity as defined by peak VO2 levels were extracted and compared. Quality Assessment of Diagnostic Accuracy Studies (QUADAS) scores were determined for each study. Results: Fourteen studies met the selection criteria. Comparison of the studies investigating reliability shows that the 6MWT has good reproducibility. The 6MWT demonstrates moderate correlation with peak VO2 levels, and ability to predict VO2 (functional capacity) dependent on distance walked. Cut-off distances vary from 300 to 490 meters depending on the study; if total distance walked remains equal or less than these values, the 6MWT retains its strong predictive value. Conclusion: The 6MWT has good reliability, moderate validity, and a significant ability to predict functional capacity in patients with CHF who do not walk greater than 490 meters.Key Words: six-minute walk test, chronic heart failure, functional capacity, peak VO2 相似文献

Interest in spatial ability has grown over the past few decades following the emergence of correlational evidence associating spatial aptitude with educational performance in the fields of science, technology, engineering, and mathematics. The research field at large and the anatomy education literature on this topic are mixed. In an attempt to generate consensus, a meta-analysis was performed to objectively summarize the effects of spatial ability on anatomy assessment performance across multiple studies and populations. Relevant studies published within the past 50 years (1969–2019) were retrieved from eight databases. Study eligibility screening was followed by a full-text review and data extraction. Use of the Mental Rotations Test (MRT) was required for study inclusion. Out of 2,450 screened records, 15 studies were meta-analyzed. Seventy-three percent of studies (11 of 15) were from the United States and Canada, and the majority (9 of 15) studied professional students. Across 15 studies and 1,245 participants, spatial ability was weakly associated with anatomy performance (rpooled = 0.240; CI at 95% = 0.09, 0.38; P = 0.002). Performance on spatial and relationship-based assessments (i.e., practical assessments and drawing tasks) was correlated with spatial ability, while performance on assessments utilizing non-spatial multiple-choice items was not correlated with spatial ability. A significant sex difference was also observed, wherein males outperformed females on spatial ability tasks. Given the role of spatial reasoning in learning anatomy, educators are encouraged to consider curriculum delivery modifications and a comprehensive assessment strategy so as not to disadvantage individuals with low spatial ability. 相似文献

The pervasiveness of sexual issues in counseling suggests the necessity of educating counseling students about relevant topics. Students enrolled in a human sexuality course anonymously submitted topical questions and secrets/fantasies. Following a content analysis, findings depicted themes of content and tone that provided curricular implications for counselor educators. 相似文献

Hope—a multidimensional positive motivational state—is particularly salient with adolescents in the school setting. Cognitive hope focuses on goal attainment cognitions whereas behavioral hope focuses on actions required for goal attainment. Studies rarely examine the contribution of each type of hope to adolescents’ academic functioning and well-being. The present study examines the contributions of cognitive and behavioral hope to academic functioning (i.e., achievement and school engagement) and well-being (i.e., stress and anxiousness) across adolescence among 5th- through 12th-grade students (n = 643). When modeled concurrently, cognitive hope significantly predicted achievement, school engagement, anxiousness, and stress (high school only); however, aspects of behavioral hope only predicted school engagement. Findings provide evidence regarding the unique contribution of both types of hope in school settings and possible areas for intervention to foster hope in developmentally appropriate ways, depending on the age of the students and outcomes of interest. 相似文献

Research on the effects of preschool dosage on children's early academic functioning has been limited despite the substantial policy implications of such work. The present study adds to a growing literature on this topic by examining how the number of years enrolled in an enhanced preschool program impacts the school readiness of primarily low-income children at kindergarten. Multi-level modeling was used to account for nesting of children within classrooms. To control for potential selection bias since children were not randomly assigned to receive one or two years of preschool, propensity score one-to-one matching was used to create the two participant groups. Receiving a second year of preschool led to significant improvements in children's early literacy and numeracy skills. Implications of these results for preschool interventions are discussed. 相似文献

This paper provides an evidence-based assessment of the University of Arkansas Libraries' collections to determine whether they are adequate to support the research and teaching needs of the marketing department. Specifically, it determined where the marketing faculty published, the characteristics of their publications, and the characteristics of their cited references. The study found that the faculty cited more recent literature and a prevalence of journal articles in their cited references. The results also demonstrate the preference of marketing faculty to work in small groups consisting of two to four collaborators. 相似文献
