Abstract

This article discusses the use of R programing language for executing a sentiment analysis of tweets pertaining to library topics. This discussion is situated within the literature of marketing and management sciences, which is employing methods of machine learning and business intelligence to make informed decision-making, and library administration, which has expressed great interest in social media engagement within its literature but has yet to adopt these types of analysis. Presented in this article is a sample code with instructions on how users may execute it within R to retrieve and analyze tweets relevant to library services. Two examples created using the code (analysis of top librarians’ tweets and analysis of posts about major book publishers) are used to demonstrate the functionality of the code. The code presented in this article may be used by libraries to analyze tweets about their library and library-related topics, which, in turn, may inform management and marketing design.  相似文献

Prestigious professional organisations have questioned the efficacy of resistive training by children or have often neglected to address weightlifting in their position papers on resistive training for children. The purpose of this paper was to address the deficit in data regarding the efficacy of training children for weightlifting and to report data regarding to safety in this population. Eleven subjects (3 female, 8 male) who had trained at the USA Weightlifting Development Centre in Shreveport Louisiana for a minimum of 22 months (mean = 28.8; SD +/- 4.4) served as subjects for this study. Means for the pool of subjects subjected to t-test to compare data obtained at each subject's initial competition with that obtained at the individual's most recent competition revealed significant positive changes in body weight, snatch weight, clean and jerk weight, and total weight lifted. The latter three were significant both in absolute weight and in weight lifted per kg of body weight. Total weight lifted at competitions plotted separately for boys and for girls across time indicated an apparently steeper slope of improvement for boys. The latter were not tested for significance because of the small sample sizes. The lack of injury in training and in 534 competitive lifts was discussed. None required medical attention or loss of training time. It was concluded that there can be no doubt regarding the efficacy of weightlifting as carried out at the USA Weightlifting Development Centre. The importance of proper application of scientific theory of conditioning in a conservative manner for this population was emphasised.  相似文献

This paper examines the official requirement for the promotion of standard English using Bourdieu's concepts of the production and reproduction of legitimate language. It explores the political drive behind the demand for this standard dialect in England and, through a survey on the views of fifty‐two 14 and 15 year olds, analyses the impact that this is having on adolescent identities in an inner‐city London school. The students perceive non‐standard English as a vehicle through which they can express their ‘true’ selves and construct a collective teenage identity. They use language to construct a division between themselves as teenagers and the adult ‘others’. Although the students do not necessarily want to use non‐standard English in the classroom, or with their teachers, educators need to consider how to afford pupils access to the ‘official language’, which grants privilege and power, without devaluing the identities which they may associate with other dialect forms. The final part of the paper explores the value of Cummin's concept of ‘transformative pedagogy’ (2002) in relation to the study of dialect with adolescents.  相似文献

Theoretical explanations, systemic response, and policy work on offenders and specific crime types are the backbone of criminal justice curricula in the United States. However, a similar breadth and depth of education on crime victims appear to be lacking in traditional criminal justice curricula, despite voluminous research on victims of crime. In this exploratory study, the authors conducted a content analysis of 679 programs from the Academy of Criminal Justice (ACJS) website directory. Departmental and course-level variables were included in the analysis. Results indicate that while more than half of the programs have faculty with expressed interests in victimization, only 11% of programs studied required coursework on crime victims and/or victimization. Implications of the results are discussed.  相似文献

How do students draw on texts read in class to explore and make sense of the world? How does role-play open up the possibilities of utilising these resources, remaking them for their own purposes? How does play, as Vygotsky suggests, enable students to achieve more? And how does being in role change the character of social relations in the classroom, enabling students to shed new light on their lives, their experiences. This essay focuses close attention on two role-plays, both involving the same pair of 11th-grade students from a school in Ramallah. The role-plays arose out of, and enabled the students to explore, literary texts that they had been studying in class: Ibsen’s A Doll’s House and Steinbeck’s Of Mice and Men. The article argues that what the students accomplished in this work is complex and needs to be understood in context. Through this account, the essay seeks to challenge those (currently fashionable) models of pedagogy that are insufficiently attentive to the histories, identities and interests of particular learners.  相似文献

In recent years it has been estimated that from 30 percent to 50 percent of the medical complaints brought to the family or general practice physician are functional in nature and may be psychosocial in origin (Harmon, Masuda & Holmes 1970). While chemotherapy may be appropriate for the patient with acute situational anxiety and psychiatric consultation may be appropriate for the severely neurotic or psychotic patient, the family practice physician has few remedies for the patient with chronic aches and pains, housewife syndrome, middle-age depression, businessman's fatigue, and a host of other quasimedical complaints.  相似文献

Although self-assessment is an important genre in both the academy and the workplace, it is often static. The resulting fixed identities are problematic in a creative economy that requires fluidity. Drawing on the work of Carruthers and Goffman, among others, we argue that memory and meditation, encompassing inventory and invention and coupled with rhetorical performance, constitute dynamic self-assessment.  相似文献
