Granularity of algorithmically constructed publication-level classifications of research publications: Identification of topics     

Peter Sjögårde  Per Ahlgren 《Journal of Informetrics》2018,12(1):133-152

The purpose of this study is to find a theoretically grounded, practically applicable and useful granularity level of an algorithmically constructed publication-level classification of research publications (ACPLC). The level addressed is the level of research topics. The methodology we propose uses synthesis papers and their reference articles to construct a baseline classification. A dataset of about 31 million publications, and their mutual citations relations, is used to obtain several ACPLCs of different granularity. Each ACPLC is compared to the baseline classification and the best performing ACPLC is identified. The results of two case studies show that the topics of the cases are closely associated with different classes of the identified ACPLC, and that these classes tend to treat only one topic. Further, the class size variation is moderate, and only a small proportion of the publications belong to very small classes. For these reasons, we conclude that the proposed methodology is suitable to determine the topic granularity level of an ACPLC and that the ACPLC identified by this methodology is useful for bibliometric analyses.  相似文献   

Managing Headship Transitions in U.S. Independent Schools     

Pearl Rock Kane  Justin Barbaro 《Peabody Journal of Education》2016,91(5):616-627

Headship transitions in U.S. independent schools represent critical organizational events that affect multiple school constituencies, including faculty, staff, and students. With recent projections forecasting a high level of impending headship transitions in independent schools, this paper seeks to capture how second-year U.S. independent school heads (n = 16) describe their transition experiences in order to provide insights into how boards, heads, and school communities can provide meaningful supports for their incoming school leaders. Further recommendations for practice and research are also provided.  相似文献

Young and in Charge: Early-Career Community College Library Leadership     

Pearl Ly 《图书馆管理杂志》2015,55(1):60-68

Although young leaders and entrepreneurs have become prevalent in the business and technology industries, academic libraries remain much more traditional. Library administrator job advertisements often require seven to ten years of library experience in progressively responsible roles as well as supervisory experience. This article shares the experiences of an early-career community college library administrator working with different generations, provides suggestions to become a manager through intentional leadership, and explores how managers learn to lead. Additionally, the author encourages community colleges to consider younger and/or newer librarians that bring a different perspective to addressing the critical issues facing community college libraries today.  相似文献   

The Meaning-Based Adult Day Care Program Managed by Nurses for Filipino Older Persons     

Pearl Ed G. Cuevas 《Educational gerontology》2015,41(9):635-641

The study aimed to develop a meaning-based adult day care program managed by nurses for Filipino older persons. Meaning-based nursing care is intended to serve as a guide in creating meaningful, focused, and structured activities for nurses in adult day care.

A mixed methods research design was used in the study. This method involved the development of a training module, meaning-based nursing care, training of registered nurses, training evaluation of nurses, and referral for interdisciplinary team meetings and consultations. Meaning-based care was approaches that address the meaning of experiences for older persons in the process of conducting adult day care services.

The study gave evidences to the ability of nurses to manage a program for older persons. Thus, the study recommends the use of the nursing model developed to prescribe guidelines in the conduct of meaning-based adult day care programs and services.  相似文献

“It wouldn't be the same without nature”—The value of nature according to Finnish upper secondary school students     

Pia Sjöblom  Lili-Ann Wolff 《The Journal of environmental education》2017,48(5):322-333

This article describes an interview study on Finnish upper secondary school students' values of nature. Even if the Finnish adolescents' interest in nature has decreased, most of the interviewees in this study regarded nature as worthy of maintenance. They valued nature for its material, aesthetic, and recreational values, as well as its diversity and future value, and because of their holistic view of nature. The nature values of the students were complex. Therefore, we suggest education that supports their value development through deliberation, authentic involvement, and outdoor activities.  相似文献   

Active relatives and health-related physical fitness in European adolescents: The HELENA Study

Abstract High physical fitness in childhood and adolescence is positively associated with favourable health-related outcomes. Our aim was to examine the relationship between relatives' (father, mother, brother, sister, and best friend) physical activity engagement and encouragement on adolescents' physical fitness. Adolescents were part of the HELENA study, a multi-centre study conducted in 10 cities from nine European countries in 2006-2008. Participants were 3288 adolescents (48% boys, 52% girls) aged 12.5-17.5 years with valid data on at least one of the three fitness variables studied: muscular strength (standing long jump), speed/agility (4×10 m shuttle run), and cardiorespiratory fitness (20 m shuttle run). The adolescents reported their relatives' physical activity engagement and encouragement. Analysis of covariance showed that relatives' physical activity engagement (father, mother, brother, and best friend) was positively related to cardiorespiratory fitness (P?相似文献   

Associations between individual and collective efficacy beliefs and students' bystander behavior     

Björn Sjögren  Robert Thornberg  Linda Wänström  Gianluca Gini 《Psychology in the schools》2020,57(11):1710-1723

This study examined whether defending and passive bystanding during peer victimization episodes were associated with individual- and classroom-level efficacy to stop peer victimization. Self-report survey data were analyzed from 1,467 Swedish fourth-grade students (mean age = 10.55) from 100 classrooms in 63 schools. Multilevel analyses revealed that, when witnessing peer victimization, students more often defended victims if they were high in defender self-efficacy and if they belonged to classrooms high in collective efficacy. In contrast, students were more likely to remain passive if they were low in defender self-efficacy and if they belonged to classrooms low in collective efficacy. Taken together, our findings suggest that efficacy beliefs both at the individual and at the classroom level contribute to explaining variability in students' bystander behaviors, which has potential implications for prevention and intervention work.  相似文献   

Role of exteroceptive background context in taste-aversion conditioning and extinction     

Trevor Archer  Per-Olow Sjödén  Lars-Göran Nilsson  Ned Carter 《Learning & behavior》1979,7(1):17-22

In two experiments, saccharin (CS) and lithium chloride (US) were paired in a context consisting of specific visual, auditory, tactual, and olfactory cues. The saccharin aversion was then extinguished in a context free from conditioning-context cues. Later, saccharin preference tests were given in the presence and absence of these cues. The results indicated that the background cues of the conditioning trial controlled the amount of saccharin drunk on extinction trials, and, furthermore, that extinction of the taste aversion was context specific; i.e., groups given extinction trials in a different (from conditioning) context retained their saccharin aversion in the conditioning context only. The results indicate an important role played by the exteroceptive context in taste-aversion conditioning.  相似文献
