The use of three‐dimensional (3D) models for education, pre‐operative assessment, presurgical planning, and measurement have become more prevalent. With the increase in prevalence of 3D models there has also been an increase in 3D reconstructive software programs that are used to create these models. These software programs differ in reconstruction concepts, operating system requirements, user features, cost, and no one program has emerged as the standard. The purpose of this study was to conduct a systematic comparison of three widely available 3D reconstructive software programs, Amira®, OsiriX, and Mimics®, with respect to the software's ability to be used in two broad themes: morphometric research and education to translate morphological knowledge. Cost, system requirements, and inherent features of each program were compared. A novel concept selection tool, a decision matrix, was used to objectify comparisons of usability of the interface, quality of the output, and efficiency of the tools. Findings indicate that Mimics was the best‐suited program for construction of 3D anatomical models and morphometric analysis, but for creating a learning tool the results were less clear. OsiriX was very user‐friendly; however, it had limited capabilities. Conversely, although Amira had endless potential and could create complex dynamic videos, it had a challenging interface. These results provide a resource for morphometric researchers and educators to assist the selection of appropriate reconstruction programs when starting a new 3D modeling project.

Academic librarianship is very much concerned with the scholarship of others, but what do we know about the scholarship of librarians? This empirical study examines the relationship between author demographics, article topic, and, in particular, faculty and librarian authorship collaboration in the academic library literature. Extensive data collection facilitated the analysis of trends, correlations, and frequencies. Significant findings were found regarding the number of authors, article type, and paper topic in the context of faculty and librarian authorship collaboration. 相似文献

The relationship between student communication motives and perceived instructor communicator style 总被引:1,自引:0,他引:1

The purpose of this study was to examine the relationship between student communication motives (i.e., relational, functional, participatory, excuse‐making, sycophantic) and perceived instructor communicator style (i.e., friendly, impression leaving, relaxed, contentious, attentive, precise, animated, dramatic, open, dominant). Participants were 228 undergraduate students enrolled in a variety of communication courses at a small Midwestern university. Results indicate that (a) the perceived instructor communicator style attributes of impression leaving, friendly, and contentious predict student use of the relational motive, (b) the attribute of friendly predicts student use of the functional motive, (c) the attributes of animated, contentious, and friendly predict student use of the participatory motive, (d) the attributes of attentive and contentious predict student use of the excuse‐making motive, and (e) the attributes of contentious and friendly predict student use of the sycophantic motive. 相似文献

This paper is part of a larger program of research assessing variables that underlie quantitative deceptiveness ratings. Several recent theoretical approaches, including Information Manipulation Theory (IMT), propose that deceptive messages are best understood as varying along two or more dimensions. At the same time, researchers have increasingly moved from dichotomous deception judgments to continuous deception ratings. This paper questions the validity of scaling degrees of deceptiveness along a single dimension, and argues that gradations in perceived deceptiveness reflect both the type of information manipulated and the severity of the consequences of the deception. This reasoning was tested with alxl experiment (N = 236) in which both the type of information manipulated and the severity of the consequences were systematically varied. As predicted, the results suggest that false messages (i.e., quality violations) are rated as more deceptive than lies of omission (i.e., quantity violations) when lie severity is low, but this difference diminishes as lie severity increases. In other words, false messages were rated as deceptive regardless of severity, but messages omitting information were rated as deceptive as false messages only when the consequences were serious. The implications for measuring deception are discussed. 相似文献

The instrument commonly employed in instructional communication to measure affective learning was subjected to tests of its construct validity as a measure of higher‐order affective learning. The results indicate the instrument is a satisfactory instrument for this purpose. Newer measures of higher‐order affective learning were found to be highly associated with the older measure. Teacher evaluation measures were found to be distinct from both the newer and the older affective learning measures. The construct validity of the commonly used affective learning instrument is good. 相似文献

An argument is advanced for the propositions that a lack of statistically significant findings does not automatically justify rejecting a scientific article for publication or mean that the findings are necessarily uninformative. Systematically declining publication for nonsignificant results leads to negative consequences that include distorting scientific literatures, making hypotheses and theories less falsifiable, depriving meta-analyses of an accurate sample of prior findings, and encouraging questionable research practices. Providing effect sizes and confidence intervals can make findings more informative, regardless of whether the finding is p < .05. 相似文献

The problem of how to rank academic journals in the communication field (human interaction, mass communication, speech, and rhetoric) is one of practical importance to scholars, university administrators, and librarians, yet there is no methodology that covers the field's journals comprehensively and objectively. This article reports a new ranking methodology based in empirical criteria. The new system relates independent measures of the prestige of the field's doctoral departments to information about where faculty members from those departments have published scholarly articles. This new approach identifies the field's most influential journals as those that more frequently publish the work of the field's top scholars and programs as perceived by their peers. This system was used to compute prestige weights (P-weights) for 65 communication journals. P-weights were found to be strongly correlated with ISI Web of Science journal impact factor scores and can be used to identify an overall prestige hierarchy for communication journals as well as prestige rankings by subject specialty. 相似文献
