MARC to BIBFRAME: Converting the PCC to Linked Data     

Jacquie Samples  Ian Bigelow 《Cataloging & classification quarterly》2020,58(3-4):403-417

Abstract

The Program for Cooperative Cataloging (PCC) has formal relationships with the Library of Congress (LC), Share-VDE, and Linked Data for Production Phase 2 (LD4P2) for work on Bibliographic Framework (BIBFRAME), and PCC institutions have been very active in the exploration of MARC to BIBFRAME conversion processes. This article will review the involvement of PCC in the development of BIBFRAME and examine the work of LC, Share-VDE, and LD4P2 on MARC to BIBFRAME conversion. It will conclude with a discussion of areas for further exploration by the PCC leading up to the creation of PCC conversion specifications and PCC BIBFRAME data.  相似文献

杨守忠 《兰台世界》2020,(4):126-128

1926年4月27日,因无法忍受日本资本家的残酷压榨和剥削,大连福岛纺织株式会社1000余名工人举行了声势浩大的罢工。罢工过程中,日本资本家采取了种种惨无人道的压迫手段逼迫工人复工。在中国共产党的领导下,工人们团结一致,坚定信念,最终取得罢工斗争的胜利,充分展示了中国工人阶级的强大力量,而中国共产党的领导对此次罢工的胜利起到了决定性的作用。  相似文献   

声像档案视域下非物质音乐文化遗产的保护与传承     

张国廷 《档案管理》2020,(3):80-81

非物质音乐文化遗产是一个地区历史进程中风土人情的体现,是当地人民在生产生活中的文化结晶,它凝聚了中国千百年来的历史,是中国非物质文化遗产的重要组成部分。随着社会的不断发展,非物质音乐文化遗产的表现形式与现代审美之间的距离越来越大,直接导致非物质音乐文化遗产的传承面临断层。由此,对非物质音乐文化遗产的保护与传承工作迫在眉睫。本文探讨了应用现代声像技术开展非物质音乐文化遗产的保护工作,希望为传统音乐文化遗产的保护与传承提供一些有价值的参考。  相似文献   

The link between student-perceived teacher talk and student enjoyment,anxiety and discursive engagement in the classroom     

Gaowei Chen  Jiahong Zhang  Carol K. K. Chan  Sarah Michaels  Lauren B. Resnick  Xiaorui Huang 《British Educational Research Journal》2020,46(3):631-652

This study seeks to understand the emotional connection of teachers' academically productive talk (APT) with student learning from the students' perspective. Using a sample of 2,225 students (N_{7th grade} = 1,146 and N_{8th grade} = 1,079) from 16 middle schools in a city of China, we investigate the relationship between students' perceptions of their teachers’ APT, student emotions (enjoyment and anxiety) and their discursive engagement with others in the mathematics classroom. Results from structural equation modelling and mediation analysis show that after controlling for gender, family resources and mathematics achievement, student-perceived teacher APT was positively associated with their discursive engagement with classmates. Furthermore, student enjoyment and anxiety in class mediated the relationship between student-perceived teacher APT and student discursive engagement with classmates. Multi-group analysis revealed that the model was invariant across genders and grades, indicating that the associations were applicable to male and female students as well as to seventh and eighth graders. These findings shed light on the emotional relationship of teacher APT with the discursive engagement of their students. Although prior research observes a positive relationship between teacher productive classroom talk and student discursive engagement primarily through classroom observations and teacher reflections, this study provides evidence from the students’ perspective and highlights the mediating role of student emotions in the relationship.  相似文献   

Impact of combining data from multiple instruments on performance of patient-based real-time quality control     

Qianqian Zhou  Tze Ping Loh  Tony Badrick  Chun Yee Lim 《Biochemia medica : ?asopis Hrvatskoga dru?tva medicinskih biokemi?ara / HDMB》2021,31(2)

IntroductionIt is unclear what is the best strategy for applying patient-based real-time quality control (PBRTQC) algorithm in the presence of multiple instruments. This simulation study compared the error detection capability of applying PBRTQC algorithms for instruments individually and in combination using serum sodium as an example.Materials and methodsFour sets of random serum sodium measurements were generated with differing means and standard deviations to represent four simulated instruments. Moving median with winsorization was selected as the PBRTQC algorithm. The PBRTQC parameters (block size and control limits) were optimized and applied to the four simulated laboratory data sets individually and in combination.ResultsWhen the PBRTQC algorithm were individually optimized and applied to the data of the individual simulated instruments, it was able to detect bias several folds faster than when they were combined. Similarly, the individually applied algorithms had perfect error detection rates across different magnitudes of bias, whereas the error detection rates of the algorithm applied on the combined data missed smaller biases. The performance of the individually applied PBRTQC algorithm performed more consistently among the simulated instruments compared to when the data were combined.DiscussionWhile combining data from different instruments can increase the data stream and hence, increase the speed of error detection, it may widen the control limits and compromising the probability of error detection. The presence of multiple instruments in the data stream may dilute the effect of the error when it only affects a selected instrument.  相似文献

Independent reading in rural China’s elementary schools: A mixed-methods analysis     

《International Journal of Educational Development》2020

Independent reading—unassigned reading for personal pleasure—has been shown to be an important driver of reading skills and academic success. Children that commonly read for pleasure exhibit higher academic performance. However, little research has been done on independent reading in rural China, where the education system is charged with schooling tens of millions of students. Many rural students fall behind their urban counterparts in school, with potentially troubling implications for China’s ongoing development. This article explores the prevalence of independent reading and its associations with reading ability and academic performance among rural students. Using a mixed methods approach, we analyze quantitative data from a survey of 13,232 students from 134 rural schools and interviews with students, teachers, principals, and caregivers. We find that independent reading is positively and significantly correlated with reading ability as well as standardized math and Chinese tests scores. Despite such correlations, only 17 percent of students report reading for pleasure for an hour a day. Interview findings suggest that inaccessible bookstores, curriculum constraints, unsupportive home environments, low availability of appealing and level-appropriate books, and insufficient school investment in reading resources may explain the low prevalence of independent reading.  相似文献   

Surviving Being Dark: A Pedagogy of the Sacred for Survival in a Divided Society     

Karen E. Mosby 《Religious education (Chicago, Ill.)》2020,115(3):304-314

Abstract

Historically, Blacks have out of necessity prioritized survival in educating their younger generations for existence in the racially hostile and divided context of the U.S. This education and religious education has occurred formally and informally in homes, schools, community organizations, and in congregations. This paper examines three aspects of survival: survival and emancipatory education, survival and justice, and survival with emerging Black generations. Three examples will be offered that highlight each aspect of survival. The examples will demonstrate how education generally and religious education in particular have undergirded pedagogies of the sacred for the survival of Black life.  相似文献   

Extended Validation of the Korean Version of the Quality of Life Survey     

SeYun Park  Erin Reifsteck  Diane L. Gill 《Measurement in physical education and exercise science》2019,23(2):110-117

In this study, we examined the factor structure and reliability of the Korean Quality of Life (KQoL) survey and compared the KQoL survey to both the World Health Organization Quality of Life-Brief Version (WHOQOL-BREF) and the Satisfaction with Life Scale (SWLS). We also assessed associations between KQoL scores and physical activity (PA) participation. Participants were 557 (male = 281, female = 276) healthy Korean adults with ages between 18 and 71 years (M = 33.2, SD = 14.2). Results of confirmatory factor analyses confirmed the 7-subscale model and indicated acceptable values supporting convergent validity (χ² = 1,678.758, df = 443, p < .001, RMSR = .045, RMSEA = .071, TLI = .880, CFI = .892). Correlations of KQoL subscales with similar subscales of WHOQOL-BREF and with SWLS supported concurrent validity. Results confirm that the KQoL survey can assess multidimensional aspects of quality of life (QoL), including spiritual, physical, social, and psychological. KQoL scores were positively related to PA participation, in line with previous research supporting the positive association of PA with QoL.  相似文献
