The Media and Criminologists: Interactions and Satisfaction     

Richard Tewksbury  Alexis Miller  Matthew T. DeMichele 《Journal of Criminal Justice Education》2013,24(2):227-243

Traditionally, academic criminologists have addressed two audiences—other academics and students—while largely ignoring other segments of society. Frequently neglected is attention to educating the public. This paper uses a random sample of American Society of Criminology (ASC) members to measure the level of interaction with and attitudes toward criminologists working with the media. Findings suggest that most criminologists have participated in an isolated incidence of working with the media, tend to be generally satisfied with this experience, and perceive working with the media as a worthwhile endeavor for criminologists.  相似文献   

Is Criminology Out-of-Date? A Research Note on the Use of Common Types of Data     

Matthew S. Nelson  Alese Wooditch  Shaun L. Gabbidon 《Journal of Criminal Justice Education》2013,24(1):16-33

There is a need to explore trends in data use by researchers in criminology to assess the limitations of the knowledge base in the discipline. The current study explores the use of data published in three top criminology journals over a 10-year period to review: (1) data types (primary, secondary, or both), (2) the age of the data, and (3) whether scholars using data at least a decade old mention it as a limitation. The study found that the time dimension of data varied by publication source. A heavy reliance on secondary data was observed across all journals. Studies using only secondary data tended to have older data on average when compared to other data types. A majority of articles using data at least a decade old did not mention it is a shortcoming. The paper concludes by discussing advantages and disadvantages of relying on secondary data within the discipline of criminology.  相似文献   

Reconcilable Differences: Conflict and Collegiality in a Unionized Community College Environment     

Matthew Hartley 《Community College Journal of Research & Practice》2013,37(4):318-336

Faculty unions are a prominent, though a comparatively recent, feature of American higher education. Today, a vast majority of community colleges have a unionized faculty. A number of researchers in the 1970s speculated that the presence of unions signaled the end of collegial shared governance and that interactions between administrators and unions would become increasingly adversarial. Subsequent experience suggests that the dire predictions were overblown. However, little institution-level research has been done to understand how unionization has affected academic governance. This study examines the governance system at a large, urban community college. The findings indicate that though at times relations are contentious, there are levels of conflict. Further there are a number of factors that tend to mitigate conflict and allow for collegial decision making. These include utilizing personal ties between members of the administration and the union, sharing data openly and also working together to collectively make sense of “the facts” before discussing possible resolutions to the presenting issue, and establishing an institutional norm that values finding solutions rather than scoring political points.  相似文献   

Critical Issues Facing America's Community Colleges: A Summary of the Community College Futures Assembly 2008     

Matthew J. Basham  Dale F. Campbell  Pilar Mendoza 《Community College Journal of Research & Practice》2013,37(11):857-870

Three focus groups consisting of board of trustee members, community college presidents, senior administrators, administrators, and faculty members developed critical issues facing community colleges with respect to instructional planning and services; planning, governance, and finance; and workforce development. Thereafter, the delegation of more than 200 voted on various aspects of the most critical issue divulged in the 2008 Community College Futures Assembly: general education assessment is coming. The findings, including opportunities and challenges, potential implications for community college administrators, and future research topics are also discussed, mostly in the context of workforce development opportunities.  相似文献   

Exploring the Underlying Factor Structure of the Parent Reading Belief Inventory (PRBI): Some Caveats     

Jorge E. Gonzalez  Aaron B. Taylor  Matthew J. Davis  Minjung Kim 《Early education and development》2013,24(2):123-137

Although mainstream preschool programs have been in existence since the 1970s, little is known about the ways in which typical children attempt to understand what it means for a peer to have a disability. In this study, 4-year-old children without disabilities who were enrolled in a mainstream preschool class explained their peers' disabilities by referring to concepts of immaturity, accident, or adaptive equipment to account for the behavioral differences that they observed. The implications of these cognitions for children's developing attitudes and behaviors toward peers with disabilities are discussed.  相似文献   

Centrality of enactive experiences,framing, and motivation to student teachers’ emerging professional identity     

Fanni Liu Coward  Doug Hamman  Leah Johnson  Matthew Lambert  John Indiatsi  Li Zhou 《Teaching Education》2013,24(2):196-221

Professional identity has emerged as a common theme in teacher development research, and the student-teaching practicum is often identified as foundational to identity development. In the context of the student-teaching practicum, interactions with cooperating teachers and pupils are believed to comprise the press for professional identity development, though theory-based explanations are often neglected in the literature, and findings are not always consistent. To address this issue, we used grounded theory to articulate a model explaining the relations among three constructs important to the process of identity development of student teachers (n = 14). Our findings are organized around a model that highlights the phenomenon of “negotiating who I am as a teacher,” which helps us describe differences between student teachers who changed identity vs. those that did not, and psychological and contextual reasons for renegotiation of identity. Discussion focuses on comparisons with previous models and possible implications for teacher education.  相似文献   

Efficacy of using non-linear pedagogy to support attacking players’ individual learning objectives in elite-youth football: A randomised cross-over trial     

Simon J. Roberts  James R. Rudd  Matthew J. Reeves 《Journal of sports sciences》2020,38(11-12):1454-1464

ABSTRACT

The present study examined the efficacy of a coaching curriculum, based on non-linear pedagogy, on improving attacking players’ individual learning objectives (ILOs) in elite-youth football. Participants included 22 attacking players (i.e., centre-forwards, wide-players and attacking midfield players) from a professional football academy in England. The players were randomly appointed to both control (CON) and intervention (INT) periods following baseline measures. The INT (non-linear) and CON (linear) periods were both designed to support the ILOs provided to each player as part of the elite player performance plan. The study adopted a randomised cross-over design and ILOs considered important for attacking players (i.e., strong foot finishing, weak foot finishing, 1-v-1 and decision-making) were evaluated using the Loughborough Shooting Skill Test. The results showed significant differences for INT in 1-v-1 (P< 0.02) and decision-making (P< 0.01). However, there were no significant differences for strong foot finishing, weak foot finishing or time taken. These results support non-linear pedagogy in developing 1-v-1 game play and decision-making but not for technical shooting proficiency.  相似文献   

Sensemaking and crisis revisited: the failure of sensemaking during the Flint water crisis     

William D. Nowling  Matthew W. Seeger 《Journal of Applied Communication Research》2020,48(2):270-289

ABSTRACT

This study operationalized Weick’s [(1988). Enacted sensemaking in crisis situations. Journal of Management Studies 25(4), 305–317 and (1993). The collapse of sensemaking in organizations: The Mann Gulch disaster. Administrative Science Quarterly, 38, 628–652] theory of enacted sensemaking to examine the communication processes associated with the Flint Water Crisis of 2014–2015. A content analysis of 389 emails and attachments from a total population of N?=?37,376 pages of publicly released e-mails and documents pertaining to Flint’s water issues, identified examples of failed sensemaking by government officials. These failures hastened and intensified a growing crisis of lead contamination and an outbreak of Legionnaires disease associated with Flint’s municipal water system. Analysis of email messages suggests that strong commitments by top leaders and limited capacity were important factors as were efforts to create and maintain consensus among officials. The Flint Water Crisis offers an important application of sensemaking theory and its utility for both organizational and risk communication scholars and for practical application. The authors emphasize the importance of questioning previous assumptions and commitments, insuring that communication practitioners are involved in decisions, and avoiding over reliance on image repair as a strategic response.  相似文献   

Effects of purposeful soccer heading on circulating small extracellular vesicle concentration and cargo     

Eric R. Muoz  Jaclyn B. Caccese  Brittany E. Wilson  Kyle T. Shuler  Fernando V. Santos  Carolina T. Cabn  John J. Jeka  Dianne Langford  Matthew B. Hudson 《运动与健康科学(英文)》2021,10(2):122

BackgroundConsidering the potential cumulative effects of repetitive head impact (HI) exposure, we need sensitive biomarkers to track short- and long-term effects. Circulating small extracellular vesicles (sEVs) (<200 nm) traffic biological molecules throughout the body and may have diagnostic value as biomarkers for disease. The purpose of this study was to identify the microRNA (miRNA) profile in circulating sEVs derived from human plasma following repetitive HI exposure.MethodsHealthy adult (aged 18–35 years) soccer players were randomly assigned to one of 3 groups: the HI group performed 10 standing headers, the leg impact group performed 10 soccer ball trapping maneuvers over 10 min, and the control group did not participate in any soccer drills. Plasma was collected before testing and 24 h afterward, and sEVs were isolated and characterized via nanoparticle tracking analysis. Next-generation sequencing was utilized to identify candidate miRNAs isolated from sEVs, and candidate microRNAs were analyzed via quantitative polymerase chain reaction. In silico target prediction was performed using TargetScan (Version 7.0; targetscan.org) and miRWalk (http://mirwalk.umm.uni-heidelberg.de/) programs, and target validation was performed using luciferase reporter vectors with a miR-7844-5p mimic in human embryonic kidney (HEK) 293T/17 cells.ResultsPlasma sEV concentration and size were not affected across time and group following repetitive HI exposure. After 24 h, the HI read count from next-generation sequencing showed a 4-fold or greater increase in miR-92b-5p, miR-423-5p, and miR-24-3p and a 3-fold or greater decrease in miR-7844-5p, miR-144-5p, miR-221-5p, and miR-22-3p. Analysis of quantitative polymerase chain reaction revealed that leg impact did not alter the candidate miRNA levels. To our knowledge, miR-7844-5p is a previously unknown miRNA. We identified 8 miR-7844-5p mRNA targets: protein phosphatase 1 regulatory inhibitor subunit 1B (PPP1R1B), LIM and senescent cell antigen-like domains 1 (LIMS1), autophagy-related 12 (ATG12), microtubule-associated protein 1 light chain 3 beta (MAP1LC3B), integrin subunit alpha-1 (ITGA1), mitogen-activated protein kinase 1 (MAPK1), glycogen synthase kinase 3β (GSK3β), and mitogen-activated protein kinase 8 (MAPK8).ConclusionCollectively, these data indicate repetitive HI exposure alters plasma sEV miRNA content, but not sEV size or number. Furthermore, for the first time we demonstrate that previously unknown miR-7844-5p targets mRNAs known to be involved in mitochondrial apoptosis, autophagy regulation, mood disorders, and neurodegenerative disease.  相似文献   

Reliably Assessing Growth with Longitudinal Diagnostic Classification Models     

Matthew J. Madison 《Educational Measurement》2019,38(2):68-78

Recent advances have enabled diagnostic classification models (DCMs) to accommodate longitudinal data. These longitudinal DCMs were developed to study how examinees change, or transition, between different attribute mastery statuses over time. This study examines using longitudinal DCMs as an approach to assessing growth and serves three purposes: (1) to define and evaluate two reliability measures to be used in the application of longitudinal DCMs; (2) through simulation, demonstrate that longitudinal DCM growth estimates have increased reliability compared to longitudinal item response theory models; and (3) through an empirical analysis, illustrate the practical and interpretive benefits of longitudinal DCMs. A discussion describes how longitudinal DCMs can be used as practical and reliable psychometric models when categorical and criterion‐referenced interpretations of growth are desired.  相似文献
