No harmless child labor: The effect of child labor on academic achievement in francophone Western and Central Africa     

《International Journal of Educational Development》2021

This study empirically examines the effect of child labor on academic achievement in 10 francophone Western and Central African countries. The data were taken from the Programme d’Analyse des Systèmes Educatifs de la CONFEMEN and comprised characteristics of 25,288 grade six students across 1803 schools. Two-stage least squares analysis highlights that child labor undermines academic achievement regardless of subject, gender, and age. It lowers reading and mathematics scores for both genders and for children under 12 and over 13 years. Child labor therefore hinders human capital accumulation in African countries, and it takes place at the cost of future prosperity.  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   

Food (in)security communication: a Journal of Applied Communication Research forum addressing current challenges and future possibilities     

Megan K. Schraedley  Hamilton Bean  Sarah E. Dempsey  Mohan J. Dutta  Kathleen P. Hunt  Sonia R. Ivancic 《Journal of Applied Communication Research》2020,48(2):166-185

ABSTRACT

This forum brings together food, (in)security, and communication. The authors participating in this forum center communication as both process and tool for understanding, mitigating, and making meaning of food (in)security. The nine authors together discuss the role of communication in food (in)security, the central challenges for scholars and practitioners working on food (in)security, and the creative possibilities and impacts influencing the future of food (in)security. The forum produces a call for applied scholars to re-imagine communication frameworks in order to make meaningful differences in their communities.  相似文献   

Diversity Literary Awards: A Tool for Assessing an Academic Library’s Collection     

Laurel Kristick 《资料收集管理》2020,45(2):151-161

Abstract

Diversity literary awards and other sources were used to create a list of high-quality titles written by and about underrepresented groups. This list was used to assess the diversity and inclusiveness of the library collections of a land-grant university in the Pacific Northwest and compare it to peer institutions. Gaps in the collection and acquisition processes were identified and will be used to improve the processes to increase the number of diverse titles added to the library’s collections.  相似文献

Health-related fitness knowledge growth in middle school years: Individual- and school-level correlates     

Xihe Zhu  Justin A. Haegele  Haichun Sun 《运动与健康科学(英文)》2020,9(6):664-669

BackgroundHealth-related fitness knowledge (HRFK) has been an essential concept for many health and physical education programs. There has been limited understanding and longitudinal investigation on HRFK growth. This longitudinal study examined HRFK growth and its individual- and school-level correlates in middle school years under 1 curriculum condition: Five for Life.MethodsParticipants were 12,044 students from 47 middle schools. Data were collected at both individual/participant and school/institution levels. Individual-level variables included gender, grade, and HRFK test scores. School-level variables included percentage of students receiving free and reduced meals (FARM), student-to-faculty ratio for physical education, and school academic performance (SAP). We used hierarchical linear modeling to examine HRFK 3-year growth in relation to individual- and school-level correlates.ResultsThe average HRFK score at 6th grade for females was 42.81% ± 1.32%. The predicted HRFK growth was 17.06% ± 1.02% per year, holding other factors constant. A 1-standard deviation increase in FARM correlated with a 14.68%-point decrease in predicted test score (p = 0.02). A 1-standard deviation increase in SAP was associated with an 11.90%-point increase in HRFK score. Males had a significantly lower growth rate than females during the middle school years (0.78%/year, p = 0.02).ConclusionThe result showed that both individual- and school-level variables such as gender, FARM, and SAP influenced HRFK growth. Educators should heed gender differences in growth curves and recognize the correlates of school-level variables.  相似文献

东盟区域龙狮运动国际传播的伦理困境     

王湘丽  张智 《体育科技文献通报》2020,(2):11-13

东盟区域龙狮运动传播过程中伦理困境的解决是促进龙狮运动在国际上传播的重要影响因素。面对传播者的行为瓶颈问题,应从提高传播者的道德意识做起;面对传播媒介沦陷的问题,应注意龙狮运动传播媒介作用的正确发挥;面对中西方文化差异问题,应促进各国文化的融合;面对受众对龙狮运动的误解,应扩大对龙狮运动的正面宣传。深入解决龙狮运动传播的伦理困境,加快龙狮文化的国际传播脚步。  相似文献
