A contingency model of outsourcing is developed from the information systems (IS) literature and strategic management literature in order to assess the following question: What factors influence change in the extent to which an organization outsources IS functions? Based on the literature, this study identifies four IS factors-gaps in information quality, IS support quality, IS staff quality, and IS cost effectiveness-and three organizational factors-the gap in financial performance, strategic orientation, and the role of information technology in an organization-that influence the change in degree of outsourcing. These factors are hypothesized to influence the change in the extent of an organization's outsourcing of IS functions. From a mail survey of 188 top IS executives in U.S. companies, the results of analysis of covariance and bivariate correlational and multivariate regression analyses provide the following major findings: (a) This study found support for the proposed research model. (b) The change in the degree of IS outsourcing is determined by gaps in information quality, IS support quality, IS cost effectiveness, and financial performance and by the role of IT among IS and organizational factors.

The purpose of this paper is to carry out an empirical analysis of the link that exists between microfinance and poverty alleviation. The analysis is driven by literature searches on empirical works done by different researchers in different contexts. Qualitative research methodology was adopted, following a desktop approach. An empirical literature review took a centre stage in this investigation. An analysis of empirical works shows that microfinance enhances poverty alleviation despite the challenges such as the Indian Andhra Pradesh crisis. The paper is limited to a review of empirical sources of literature. A field survey, supported by an econometric analysis would have helped to generate robust results. This paper attempts to bring together the empirical works that were done in different contexts to shed light on the important relationship between microfinance and poverty. Many research works on microfinance depend upon personal anecdotes, thus this present paper attempts to compile the scattered empirical findings on microfinance and poverty alleviation.

The number of studies on social media has increased rapidly worldwide. There has been, however, little effort to assess the achievements and limitations of social media studies up to present. The purpose of this study is to provide a systematical viewpoint on social media research published by scholarly business-related journals. Our analysis focus on research topic, functionality, targeted media types, methodology, and characteristics. User research receives the most attention, followed by effect research in terms of developmental models of media research agenda. The major methodological trend is online survey. Facebook and twitter are the two most popular mediums studied in literature, and social media is mainly characterized as information sharing as well as relationship building. Two recommendations are suggested in ways to strengthen social media research: more various topics and application areas, and the rigor and diversity of research methods.

The primary purpose of the present essay is to survey the relationship between Chaucer's fatherhood and English nationalism. Chaucer as a nationalist poet with essential Englishness is a product of the pre-modern nationalist project initiated between the late thirteenth century and early fourteenth century. In this period, as Turville-Petre regards, the English nationalist identity started to rise in language and literature. Thus this essay surveys the pre-modern nationalist discourse before Chaucer and how it influenced Chaucer to spawn his own nationalist discourse. The latter half of this project, as a reception study, surveys the nationalist receptions of Chaucer in the nineteenth century, when the connection between Chaucer studies and jingoistic nationalism was highly circumstantial. In terms of Chaucer's reception, the nineteenth-century was a crucial period: during this period the nationalist discourse and Chaucer studies firmly combined and Chaucer was envisaged as a boastful nationalist poet. The essay's discussion generally revolves around Chaucer's fatherhood and his exclusive Englishness; "Chaucer the father" is nationalist rhetoric which mediates thirteenth century post-colonialism and nineteenth-century colonialism.

This paper presents a case study of the effectiveness of debate class in promoting speaking skills of advanced learners. The researcher adopted English debate techniques in an English speaking class during four-week teacher training program and investigated how teachers responded to the new technique. Forty-five middle and high school teachers participated in the study and classroom observation, pre-survey, post-survey, and focus group interviews were used as the major research methods. The teacher pre-survey results presented that teachers prefer a conversation class where they can directly acquire proper sentence patterns and speaking strategies rather than spend time in performing communicative events. The results of the focus group interview and post-survey confirmed that a debate class can meet this specific teachers' needs. Most teachers responded positively to the debate classes since: 1) debate techniques are relatively new ideas to Korean teachers; 2) debate techniques require speed and accuracy in speech; thus teachers could learn to present their ideas logically and efficiently in a limited time through repeated argument exercises. The study result implies that debate technique can be an effective vehicle in an EFL context to promote advanced learners' logical thinking skills and logical English sentence structures.

Purpose: This study aimed to develop a survey instrument to assess the Patient Safety Culture in Korean hospitals and evaluate its validity and reliability. Methods: A preliminary instrument was developed through a literature review, focus group interviews, content validity testing, and pretesting for face validity. A total of 467 hospital employees participated in the psychometric testing. Validity and reliability assessments included content validity, construct validity, criterion-related validity, and internal consistency. Results: The Korean Patient Safety Culture Survey Instrument comprised 35 items across seven factors: leadership, patient safety policy and procedure, patient safety improvement system, teamwork, non-punitive environment, patient safety knowledge and attitudes, and patient safety priority. These seven factors contributed 60.98% of the variance of the total scale. Cronbach's alpha for internal consistency was .93; the seven factors ranged from .66 to .91. Conclusion: The results of this study showed that the Korean Patient Safety Culture Survey Instrument is reliable, valid, and suitable for measuring patient safety culture in Korean hospitals.
