Recent Changes to Reference Services in Academic Libraries and Their Relationship to Perceived Quality: Results of a National Survey     

Jason Coleman  Melissa N. Mallon  Leo Lo 《图书馆管理杂志》2013,53(6):673-696

ABSTRACT

A national survey of academic librarians was conducted to examine relationships among reference service staffing changes, reference service innovations, adoption of reference technology, library type and size, and service quality. Analysis of the 606 response sets reveals trends toward reduced use of librarians and increased use of student staff at in-person service points, widespread increases in appointment-based and self-service reference, intensive efforts to reduce demand for reference by improving library instruction, and general improvements in reference service quality. Factors strongly associated with decreases or increases in quality are discussed in detail and implications for reference managers are provided.  相似文献   

Exposure of Taiwanese adolescents to pornographic media and its impact on sexual attitudes and behaviour     

Ven‐hwei Lo  Edward Neilan  Mine‐ping Sun  Shoung‐Inn Chiang 《亚洲交流杂志》2013,23(1):50-71

This article examines the use of pornographic media by Taiwanese high school students, and explores the effects of exposure to such on their attitudes and behaviour in terms of sexual permissiveness.

The results of this research indicate that more than 90 per cent of the students interviewed had at least some exposure to a variety of pornography, with males reporting significantly higher exposure frequencies than females. The results also show that exposure to pornographic media has significant effects on high school students’ sexual permissiveness and nonexclusive sexual attitudes and behaviour.  相似文献   

The scientific investigation for the study and conservation of the wooden model of S. Maria della Consolazione's church (Todi,Italy)     

Angela Lo Monaco  Elisabetta Mattei  Claudia Pelosi  Marco Santancini 《Journal of Cultural Heritage》2013,14(6):537-543

The focus of this work is the wood polychrome model of the church of S. Maria della Consolazione in Todi, an artefact whose author and historical events are not completely known except a general reference to the construction period of the church (1508–1607 AD). In this study, original and additional materials were examined in order to provide a deeper understanding of the painting and assembly techniques, and a greater awareness of how well preserved the object is, as well as an analysis of previous preservation and conservation interventions. The samples from the painted surfaces were examined by means of micro-Raman spectroscopy, fourier transform infrared (FTIR) spectrometry and internal microstratigraphic analysis. Thin sections of the wood samples were examined under an optical transmission light microscope in order to identify the botanical species. The results shown in this paper suggest the possibility that the original painted layers are made of calcium carbonate white, red ochre and indigo and they were applied by protein binder without any ground layer. Some non-original pigments were found on the model surface like Prussian blue and chrome yellow. Concerning wood components, poplar was characterized both in the original and non-original parts of the model whereas pine species were detected only in the restoration elements.  相似文献   

Mining direct antagonistic communities in signed social networks   总被引：1，自引：1，他引：0  

David Lo  Didi Surian  Philips Kokoh Prasetyo  Kuan Zhang  Ee-Peng Lim 《Information processing & management》2013

Social networks provide a wealth of data to study relationship dynamics among people. Most social networks such as Epinions and Facebook allow users to declare trusts or friendships with other users. Some of them also allow users to declare distrusts or negative relationships. When both positive and negative links co-exist in a network, some interesting community structures can be studied. In this work, we mine Direct Antagonistic Communities (DACs) within such signed networks. Each DAC consists of two sub-communities with positive relationships among members of each sub-community, and negative relationships among members of the other sub-community. Identifying direct antagonistic communities is an important step to understand the nature of the formation, dissolution, and evolution of such communities. Knowledge about antagonistic communities allows us to better understand and explain behaviors of users in the communities.  相似文献   

Contribution of discourse and morphosyntax skills to reading comprehension in Chinese dyslexic and typically developing children     

Pakey Pui-man Chik  Connie Suk-han Ho  Pui-sze Yeung  Yau-kai Wong  David Wai-ock Chan  Kevin Kien-hoa Chung  Lap-yan Lo 《Annals of dyslexia》2012,62(1):1-18

This study aimed at identifying important skills for reading comprehension in Chinese dyslexic children and their typically developing counterparts matched on age (CA controls) or reading level (RL controls). The children were assessed on Chinese reading comprehension, cognitive, and reading-related skills. Results showed that the dyslexic children performed significantly less well than the CA controls but similarly to RL controls in most measures. Results of multiple regression analyses showed that word-level reading-related skills like oral vocabulary and word semantics were found to be strong predictors of reading comprehension among typically developing junior graders and dyslexic readers of senior grades, whereas morphosyntax, a text-level skill, was most predictive for typically developing senior graders. It was concluded that discourse and morphosyntax skills are particularly important for reading comprehension in the non-inflectional and topic-prominent Chinese system.  相似文献   

Instructional practices in reformed undergraduate STEM learning environments: a study of instructor and student behaviors in biology courses     

Petra Kranzfelder  Alexander T. Lo  Marin P. Melloy  Lindsey E. Walker 《International Journal of Science Education》2013,35(14):1944-1961

ABSTRACT

Theoretically, organisational culture, instructor training, and learning space design influence how faculty teach STEM courses. Previous studies have used classroom observation protocols to characterise the range of teaching practices in mostly teacher-centered, traditional STEM classrooms. In this study, we examined the classroom behaviour of 13 STEM faculty teaching biology courses in a reformed undergraduate STEM learning environment. Our findings indicate that instructors teaching in this reformed environment guided student learning (58.4?±?1.9%) almost three times more than they presented information (20.0?±?2.2%). Students worked individually or in groups and talked to the whole class (57.1?±?1.8%) 1.5 times more than they received information (35.5?±?1.9%). We found significant positive correlation between ‘instructor presenting’ and ‘students receiving’ information (r?=?0.743, p?=?1.4?×?10^?4) and ‘instructor guiding’ and ‘student working and talking’ in class (r?=?0.605, p?=?7.2?×?10^?5), suggesting that instructors can change their own classroom behaviours and expect concurrent change in their students’ behaviours. Finally, sequencing teaching practices in high active-engagement classrooms showed instructors move and guide student group work and lead whole class discussions before lecturing to students, which could lead to deeper learning of conceptual knowledge. We discuss insights from these findings that have implications for acculturating evidence-based teaching practices in STEM departments.  相似文献

What teachers think about what they can do with data: Development and validation of the data driven decision-making efficacy and anxiety inventory     

Karee E. Dunn  Denise T. Airola  Wen-Juo Lo  Mickey Garrison 《Contemporary educational psychology》2013

Classroom level data driven decision-making (DDDM) involves the use of data to identify patterns of performance that reveal students’ academic strengths and weaknesses relative to established learning goals, and the planning of instructional practices to support academic success for all students. Although DDDM is not a new paradigm in education, little is known about what variables facilitate teacher adoption of DDDM practices. The aim of this work was to introduce two such variables, DDDM efficacy and DDDM anxiety, and a measure of these constructs, the DDDM efficacy and anxiety (3D-MEA) inventory. The 1728 participants in this study were K-12 teachers who had experienced varying levels of DDDM professional development in a Pacific Northwestern state. Exploratory factor analysis (EFA) (n = 864) and confirmatory factor analysis (CFA) (n = 864) were utilized to evaluate the psychometric properties of the 3D-MEA Inventory. Results supported a five-factor model. A discussion of the results and their implications ensue.  相似文献   

Snakes and ladders: stressing the role of meta-competencies for post-modern careers     

Alessandro Lo Presti 《International Journal for Educational and Vocational Guidance》2009,9(2):125-134

Major global changes during the last decades have influenced the individual’s work-life and career. As a result of globalisation, increasing societal complexity and flexibility, careers have lost their linearity and predictability. Traditional models of career development no longer provide a comprehensive explanation for an adequate career development. New theoretical concepts such as protean and boundaryless career attitudes are presented as options to cope with the new situation. In addition, the development of career meta-competencies and skills are introduced as an approach to foster career self-management.  相似文献   

Taiwanese families' perspectives on learning disabilities: an exploratory study in three middle schools     

Szu‐Yin Chu  Yu‐Ling Sabrina Lo 《Journal of Research in Special Educational Needs》2016,16(2):77-88

The purpose of this study was to investigate families' perspectives on learning disabilities (LD) in Taiwan. A researcher‐designed survey was sent out to families of children with or without LD from three middle schools. Data from 153 participants were gathered and analysed. The survey consisted of four sections, namely demographic information, children's reading performance, families' general understanding and perspectives of LD. Specifically, the last section of 54 Likert scale items designed to gather information about families' perspectives of LD was analysed with five domains: causes of LD (inherent or acquired), conceptions and misconceptions, attitudes (acceptance or rejection), disclosure of disabilities (willing or unwilling), and support. Results indicated that families were not familiar with educational services related to LD in schools. Additionally, families' experiences with people with disabilities resulted in different perspectives regarding the causes and conceptions about LD, and acquiring support. Families' perspectives on LD also correlated with personal characteristics, including the level of their children's reading performance, number of children and income level. The cultural implications of these findings interplay with an emphasis on academic performance are discussed.  相似文献
