Tác giả thảo luận về thiên lệ phương pháp chung trong bối cảnh mô hình phương trình cấu trúc sử dụng phương pháp bình phương tối thiểu phần (PLS-SEM). Hai tập dữ liệu đã được tạo ra thông qua mô phỏng Monte Carlo để minh họa cho cuộc thảo luận: một tập bị ô nhiễm bởi thiên lệ phương pháp chung, và tập kia không bị ô nhiễm. Một phương pháp thực tiễn được trình bày để xác định thiên lệ phương pháp chung dựa trên các yếu tố ảnh hưởng độ biến thiên được sinh ra thông qua kiểm tra đa cộng tuyến đầy đủ. Cuộc thảo luận của tác giả xây dựng trên một mô hình minh họa trong lĩnh vực hợp tác điện tử, với các đầu ra được tạo ra từ phần mềm WarpPLS. Họ chứng minh rằng kiểm tra đa cộng tuyến đầy đủ thành công trong việc xác định thiên lệ phương pháp chung với một mô hình mà vẫn đáp ứng các tiêu chí đánh giá độ hợp lệ hội tụ và phân biệt theo tiêu chuẩn dựa trên phân tích yếu tố khẳng định.

Knowledge management (KM) approaches have been broadly considered to entail either a focus on organizing communities or a focus on the process of knowledge creation, sharing, and distribution. While these two approaches are not mutually exclusive and organizations may adopt aspects of both, the two approaches entail different challenges. Some organizational cultures might be more receptive to the community approach, whereas others may be more receptive to the process approach. Although culture has been cited widely as a challenge in knowledge management initiatives, and although many studies have considered the implications of organizational culture on knowledge sharing, few empirical studies address the influence of culture on the approach taken to knowledge management. Using a case study approach to compare and contrast the cultures and knowledge management approaches of two organizations, the study suggests ways in which organizational culture influences knowledge management initiatives as well as the evolution of knowledge management in organizations. Whereas in one organization, the KM effort became little more than an information repository, in the second organization, the KM effort evolved into a highly collaborative system fostering the formation of electronic communities.

The purpose of this study was to improve the understanding of virtual team leadership occurring within existing virtual teams in a range of organizations. Qualitative data were collected through comprehensive interviews with nine virtual team leaders and members from six different organizations. A semi-structured interview format was used to elicit extensive information about effective and ineffective virtual team leadership behaviours. Content analysis was used to code the interview transcripts and detailed notes obtained from these interviews. Two independent raters categorized results into themes and sub-themes. These results provide real-world examples and recommendations above and beyond what can be learned from simulated laboratory experiments. The four most important overarching findings are described using the following headings: 1) Leadership critical in virtual teams, 2) Virtual team meeting effectiveness, 3) Personalizing virtual teamwork, and 4) Learning to effectively use different media. These findings represent the most significant and pertinent results from this qualitative data and provide direction for future research, as well as practical recommendations for leaders and members of virtual teams.

Simpson's paradox is a phenomenon arising from multivariate statistical analyses that often leads to paradoxical conclusions in the field of e-collaboration as well as many other fields where multivariate methods are employed. This work derives a general inequality for the occurrence of Simpson's paradox in path models with or without latent variables. The inequality is then used to estimate the probability that Simpson's paradox would occur at random in path models with two predictors and one criterion variable. This probability is found to be approximately 12.8 percent, slightly higher than 1 occurrence per 8 path models. This estimate suggests that Simpson's paradox is likely to occur in empirical studies, in the field of e-collaboration and other fields, frequently enough to be a source of concern.
