This paper focuses on the treatment of statistical interactions (i.e., non‐additivity) within the framework of multiple regression. The nature of statistical interactions in relation to other types of effects and the implications of interactions for analysis and interpretation are discussed. We argue that researchers using regression analyses (1) often either fail to test for interactions (2) or use inadequate methods for testing for interactions (3) and, consequently may make faulty conclusions about their data. We outline several methods of dealing with interactions with regression and discuss the strengths and weaknesses of each. Recommendations are made for the detection and treatment of interactions within regression. 相似文献

This paper advances an argument in favor of conducting and reporting confirmatory factor analyses (CFA) on existing and previously validated scales and reporting the findings of those analyses in published research. Previous evidence of scale validity does not necessarily ensure validity in subsequent uses. Instead, scale invariance is best viewed as an empirical question. The case is made that CFA facilitates rather than hinders cross-studies comparisons, and that replication is good scientific practice. Reporting the outcomes of CFA on existing scales provides useful information that facilities knowledge generation and can minimize costly scientific dead-ends. 相似文献

Confirmatory factor analysis (CFA) is an under-used and often misunderstood statistical tool. CFA provides useful information about scale dimensionality and validity. This paper offers a brief and accessible introduction to the role of CFA in communication research. Some common issues with CFA including dimensionality and model fit are addressed. More frequent and informed use of CFA would likely improve the quality of measurement in quantitative communication research. 相似文献

This study extended research on women's surname choices and terms of address. Account of unmarried women and men were examined to identify factors and dialectical tensions in their reasoning about married women's surnames. Preferences for and meanings of women's titles, surname preferences for children, and perceptions concerning commitment and love were ascertained. Sex differences were found in the rationales for surname choice. Men and women preferred women and children to adopt male surnames and preferred married women use the title of Mrs. Men and women associated differing meanings with titles of Mrs. and Ms. Finally, men were more likely than women to associate a woman's surname choice with her love for, and commitment to, her partner. 相似文献

Abstract This paper focuses on the outreach to over 3,000 students taking classes at over 80 locations within the State of Maine, as well as students taking classes nationally via the Web through the University of Maine System Network (UNE1). The discussion will briefly note the wide range of collections and services available through the University of Maine System's digital library and the Off-Campus Library Services Office. In particular, the discussion will center on reserve services for students at remote locations, using traditional paper copies and particularly electronic reserves, and the copyright issues that surround the e-reserve service. 相似文献

The eleven state universities of Florida have long shared an integrated library system architecture, but maintained separate databases. In 2009 the deans and directors of the eleven state university libraries tasked the three largest libraries to investigate the feasibility of combining all catalogs into a single bibliographic entity. With the help of a central automation group, the three successfully negotiated the fine line between sharing data and retaining the unique work created by each of the three libraries. The groundwork laid in this initiative should prove valuable to other libraries seeking to centralize functions and pool resources. 相似文献
