Executive Summary This article looks at the evolution of telework in the United States as well as the benefits and potential problems associated with this growing phenomenon. One of these issues, effective leadership of teleworkers, is the focus of the article. The authors suggest that Situational Leadership™, a leadership model which has been in use since the late 1960s, is an appropriate tool for leaders to use in successfully influencing their off-site workers. Situational Leadership™ is explained and applied to a variety of telecommuting scenarios.

The Missouri Breast Cancer Detection Demonstration Project (BCDDP) at the Cancer Research Center in Columbia, Missouri, detected 136 malignant lesions among 10,187 asymptomatic participants between 1974 and 1980. Mammography was the sole detection modality in 76 or 56% of cases (Group 1). Mammography combined with physical examination revealed 41 (30%) additional cases (Group 2). Physical examination alone detected 19 (14%) cases (Group 3). Follow-up was complete in all cases. There were 26 (19%) noninvasive and 110 (81%) invasive lesions. Positive axillary nodes were found in 34 (25%) cases, and 102 (75%) patients had negative nodes. The overall 5-year survival was 84.5%. After a minimum follow-up of 5 years and a median follow-up of 8.5 years, 108 patients are alive, 5 of whom have recurrences. Among 28 deceased patients, 9 died of causes unrelated to breast cancer. The 5-year survival of Group 1 was 95% (72/76). Among this group of patients, 84% (64/76) had negative lymph nodes. At 5 to 10 years follow-up, there have been no breast cancer-related deaths among this group, and only one patient has recurrent disease 91 months after mastectomy. Furthermore, 85% (22/26) of all noninvasive lesions were found in this group. Of the remaining 12 patients diagnosed by mammography alone but who had positive nodes, the 5-year survival was 75% (9/12). By contrast, patients diagnosed by mammography plus physical examination (Group 2) experienced a survival of 71% (29/41) at 5 years. Sixty-three percent of patients diagnosed by physical examination had negative lymph nodes. Their 5-year survival was 84%, which contrasts with a 50% 5-year survival for patients with positive nodes. In Group 3, 79% (15/19) had negative nodes. The 5-year survival rate of this group was 74% (14/19), and the 5-year survival rate of the node-negative patients with invasive disease in this group was 29% and 21% lower than that of the node-negative patients with invasive disease of Groups 1 and 2, respectively (P less than 0.01). This study suggests that improved survival in breast cancer screening program is in large measure dependent on the ability to detect lesions before they become palpable. The authors conclude that mammography is a determining factor in early diagnosis, and at 5 to 10 years contributes significantly to improved 5- and 10-year survival rates.

Executive Summary Herb Kelleher, co-founder, CEO, President and Chairman of Southwest Airlines is cited in this article as an ideal example of charismatic leadership at its best. A discussion of charismatic leadership focuses on traits and behaviors of charismatic leaders. This model is then used to examine Kelleher's traits and behaviors at Southwest Airlines, named in 1998 as the best place to work in America by Fortune Magazine. Kelleher's vision and style are seen as the driving forces of this maverick airline which has consistently posted a profit for 26 consecutive years and does things differently than any other company in the industry. The key to Southwest's success is largely thought to be the warmth and determination of its employees who mirror those same qualities in their leader. The article includes Kelleher's thoughts on leadership and concludes that there is reason to question whether the strong, personality-driven Southwest culture can survive after Kelleher retires from the helm.
