The information needs of perioperative staff: a preparatory study for a proposed specialist library for theatres (NeLH)     

Nicholas D  Williams P  Smith A  Longbottom P 《Health information and libraries journal》2005,22(1):35-43

AIMS/OBJECTIVES: To undertake an information-needs analysis of operating theatre staff in order to inform the development of a specialist library of the National Electronic Library of Health (NeLH). SETTING: Three hospitals in an NHS Trust in a rural county in the north of England. METHODS: In-depth interviews, during which staff were questioned in regard to their job roles and information needs, information-seeking behaviour, access to computers, use and perceptions of the NeLH, and what they would like from a specialist library. RESULTS: Information needs were found to concern direct care, professional and academic development, medical devices knowledge and administration. Currency and speed of delivery were the key information requirements. Poor communication appeared to be a major problem for many staff and inhibited efficient information exchange. When using the Web, both clinical and non-clinical staff searched in a similar fashion to health consumers generally, despite their need for highly specialist information. Most respondents reacted warmly to the idea of the proposed National Electronic Library for Theatre Staff (NeLTS) and made several practical suggestions for suitable material. However, access was problematic for nurses and might prove to be an obstacle to take-up of the Specialist Library. CONCLUSIONS: Communication difficulties, the fragmentation of data in the field and the consequent difficulties of finding information point to the need for an NeLTS. However, for this library to embrace and succeed with all the various groups that constitute the operating theatre staff, issues of access and digital literacy need to be addressed.  相似文献   

Optimum take-off angle in the long jump     

Linthorne NP  Guzman MS  Bridgett LA 《Journal of sports sciences》2005,23(7):703-712

In this study, we found that the optimum take-off angle for a long jumper may be predicted by combining the equation for the range of a projectile in free flight with the measured relations between take-off speed, take-off height and take-off angle for the athlete. The prediction method was evaluated using video measurements of three experienced male long jumpers who performed maximum-effort jumps over a wide range of take-off angles. To produce low take-off angles the athletes used a long and fast run-up, whereas higher take-off angles were produced using a progressively shorter and slower run-up. For all three athletes, the take-off speed decreased and the take-off height increased as the athlete jumped with a higher take-off angle. The calculated optimum take-off angles were in good agreement with the athletes' competition take-off angles.  相似文献   

The reality of friendship within immersive virtual worlds     

Nicholas John Munn 《Ethics and Information Technology》2012,14(1):1-10

In this article I examine a recent development in online communication, the immersive virtual worlds of Massively Multiplayer Online Role-Playing Games (MMORPGs). I argue that these environments provide a distinct form of online experience from the experience available through earlier generation forms of online communication such as newsgroups, chat rooms, email and instant messaging. The experience available to participants in MMORPGs is founded on shared activity, while the experience of earlier generation online communication is largely if not wholly dependent on the communication itself. This difference, I argue, makes interaction in immersive virtual worlds such as MMORPGs relevantly similar to interaction in the physical world, and distinguishes both physical world and immersive virtual world interaction from other forms of online communication. I argue that to the extent that shared activity is a core element in the formation of friendships, friendships can form in immersive virtual worlds as they do in the physical world, and that this possibility was unavailable in earlier forms of online interaction. I do, however, note that earlier forms of online interaction are capable of sustaining friendships formed through either physical or immersive virtual world interaction. I conclude that we cannot any longer make a sharp distinction between the physical and the virtual world, as the characteristics of friendship are able to be developed in each.  相似文献   

From abbey to archive: managing texts and records in early modern England     

Nicholas Popper 《Archival Science》2010,10(3):249-266

This article investigates the long-term transformations in England’s documentary storage regime wrought by the Reformation. Henry VIII’s Dissolution of the Monasteries famously resulted in the dispersal and destruction of many medieval texts and records, but he and his successors sponsored efforts to retrieve lost materials, which they then used in the formation of ecclesiastical policy. Elizabethan counselors expanded the scope of this project, applying their expertise in gathering records to secular issues and assiduously preserving their own documents. During James I’s reign, the Earl of Salisbury’s patronage gave new authority to the State Paper Office, encouraging the consolidation of a centralizing archive that integrated earlier methods of collection, preservation, and indexing in its operation and construction. The article thus offers an analytic trajectory tying the practices of Reformation to the development of expanding national archives in the seventeenth century.  相似文献   

Self-Initiated Learning Activities of Experienced Public School Teachers: Methods,sources, and relevant organizational influences     

Margaret C. Lohman  Nicholas H. Woolf 《Teachers and Teaching》2013,19(1):59-74

The self-initiated learning activities of experienced public school teachers are examined in this study. Twenty-two experienced teachers were interviewed to develop a greater understanding of the types of self-initiated learning activities in which they engage and the organizational characteristics that influence their participation in those activities. Analysis of the data showed that experienced teachers engaged in three types of self-initiated learning activities: knowledge exchanging, experimenting, and environmental scanning. Participation in these activities was influenced by the availability of resources, physical layout, and level of centralization in their schools. Implications of these findings for theory, practice, and future research in teacher learning and development are discussed.  相似文献

Estimating the Effect on Grades of Using Multiple-Choice Versus Constructive-Response Questions: Data From the Classroom     

Stephen Hickson  W. Robert Reed  Nicholas Sander 《Educational Assessment》2013,18(4):200-213

This study investigates the degree to which grades based solely on constructed-response (CR) questions differ from grades based solely on multiple-choice (MC) questions. If CR questions are to justify their higher costs, they should produce different grade outcomes than MC questions. We use a data set composed of thousands of observations on individual students in introductory economics classes at a large public university. We note that the instructors of these classes made conscientious efforts to write CR questions that assessed higher levels of learning (Bloom, 1956 Bloom, B. S. 1956. Taxonomy of educational objectives: The classification of educational goals, handbook 1: Cognitive domain. New York: McKay..  [Google Scholar]). Despite this, we find relatively little difference in grade outcomes. Our analysis suggests that switching from an all-CR assessment to an all-MC assessment would produce grade variations that are similar to the differences that are observed for students across different tests. Although other studies have focused on test scores, frequently AP test scores, our study is the first to focus attention on university grades. We hope that our inability to identify substantial benefits to CR questions in terms of grades will stimulate further research to identify substantive benefits from using the more costly CR questions.  相似文献   

On Fitting a Multivariate Two-Part Latent Growth Model     

Nicholas D. Myers  Soyeon Ahn  Ying Jin 《Structural equation modeling》2013,20(1):131-147

The purpose of this study was to explore the influence of the number of targets specified on the quality of exploratory factor analysis solutions with a complex underlying structure and incomplete substantive measurement theory. Three Monte Carlo studies were performed based on the ratio of the number of observed variables to the number of underlying factors. Within each study, communality, sample size, and the number of targets were manipulated. Outcomes included a measure of congruence and a measure of variability with regard to the rotated pattern matrix. The magnitude of the main effect for the influence of the number of targets on congruence and variability ranged from moderate to large. The magnitude of the interaction between the number of targets and level of communality ranged from small to moderate with regard to congruence and variability. Consistent with theoretical expectations, the minimum number of targets to specify to be reasonably assured of obtaining an accurate solution varied across study conditions.  相似文献
