Servant Leadership and its Relationships with Core Self-Evaluation and Job Satisfaction
Servant leadership is a growing topic in the leadership literature. Our study considered servant leadershipâs relationship to two outcomes, core self-evaluation and job satisfaction. The former is particularly noteworthy because if servant leadership predicts core self-evaluation this would confirm that servant leadership affects important changes in employees as people, a central tenet of servant leadership. In addition, if servant leadership predicts core self-evaluation, this could add to the question of whether core self-evaluation is a non-changeable personality trait or is potentially malleable. We conducted a field study of three firms and found that servant leadership predicts both core self-evaluation and job satisfaction, and that core self-evaluation also predicts job satisfaction. This study contributes to servant leadership, and in general to values-based leadership, by observing a predictive relationship to core self-evaluation, which potentially adds new information about the impact servant leadership can have on individuals. This study confirms the findings of previous authors who found that servant leadership predicts job satisfaction
Multilevel Marketing Diffusion and the Risk of Pyramid Scheme Activity: The Case of Fortune HiâTech Marketing in Montana
While statisticians have simulated the expected rate of growth in pyramid schemes, this research examines actual data on the spread of an alleged pyramid scheme in Montana. Fortune Hi-Tech Marketing (FHTM) was a multilevel marketing firm, sued by six states and the Federal Trade Commission and permanently shut down in 2014. Data from a settlement with the State of Montana provide a population of participants in a geographic region with definable markets and offer unique insights into local contagion. The authors analyze the pattern of FHTM adoption within a diffusion-of-innovation framework. The findings confirm that nearly all adoption results from interpersonal influence (i.e., imitation) and indicate that participation is higher in counties with larger economic contractions. The authors add to existing guidance about early indicators of fraudulent activity and discuss intervention and prevention strategies that reflect the imitative nature of this diffusion process
Adjuvant radiation therapy, androgen deprivation, and docetaxel for high-risk prostate cancer postprostatectomy: Results of NRG Oncology/RTOG study 0621.
BACKGROUND: Phase 3 trials have demonstrated a benefit from adjuvant radiation therapy (ART) for men who have adverse factors at radical prostatectomy (RP). However, some patients have a high risk of progression despite ART. The role of systemic therapy with ART in this high-risk group remains to be defined.
METHODS: Patients who had either a post-RP prostate-specific antigen (PSA) nadirâ\u3eâ0.2âng/mL and a Gleason score â„7 or a PSA nadir â€0.2âng/mL, a Gleason score â„8, and a pathologic tumor (pT) classificationââ„âpT3 received 6 months of androgen-deprivation therapy (ADT) plus radiotherapy and 6 cycles of docetaxel. The primary objective was to assess whether the addition of ADT and docetaxel to ART resulted in a freedom from progression (FFP) rateââ„â70% compared with an expected rate of 50%. Multivariate logistic and Cox regression analyses were used to model associations between factors and outcomes.
RESULTS: In total, 74 patients were enrolled. The median follow-up was 4.4 years. The pathologic tumor classification was pT2 in 4% of patients, pT3 in 95%, and pT4 in 1%. The Gleason score was 7 in 18% of patients and â„8 in 82%. Post-RP PSA levels were â€0.2âng/mL in 53% of patients and \u3e0.2âng/mL in 47%. The 3-year FFP rate was 73% (95% confidence interval, 61%-83%), and the 3-year cumulative incidence of biochemical, distant, and local failure was 26%, 7%, and 0%, respectively. In multivariate models, postprostatectomy PSA nadir was associated with 3-year FFP, Gleason score, and PSA with biochemical failure. Grade 3 and 4 neutropenia was common; however, only 3 episodes of febrile neutropenia occurred. Late toxicities were not impacted by the addition of systemic therapy.
CONCLUSIONS: Combined ADT, docetaxel, and ART for men with high-risk prostate cancer after prostatectomy exceeded the prespecified study endpoint of 70% 3-year FFP. Phase 3 trials assessing combined local and systemic therapies for these high-risk patients are warranted. Cancer 2017;123:2489-96. © 2017 American Cancer Society

Cultures of Servant Leadership and Their Impact
Servant Leadership has primarily been studied at the level of individual leaders and their impact, yet Greenleaf, who first formally proposed the idea in 1970, also considered the construct as an important institutional element. Further, because it is values-based, and culture is the organizational mechanism for developing and transmitting shared values, an organizational lens for studying servant leadership is also needed. The current study of three firms examines organizational differences in servant leadership. We found organizational differences in levels of servant leadership, suggesting a cultural explanation. We also found that individual (i.e., supervisor) and organizational (i.e., cultural) servant leadership have different effects on employee outcomes, suggesting a unique asset attributable to a culture of servant leadership. Finally, we found that employees high in core self-evaluation are more likely to identify leaders with a servant leadership orientation, suggesting that such individuals can facilitate cultural transmission of servant leadership in an organization. Implications to theory and practice are discussed
Living in a Gender-Binary World: Implications for a Revised Model of Consumer Vulnerability
Baker, Gentry, and Rittenburgâs (2005) model of consumer vulnerability outlines the personal, social, and structural characteristics that frame consumersâ experiences of vulnerability in the marketplace. Later applications and enhancements have expanded consumer vulnerability theory. While the theory has been applied in numerous settings, to date it has not been used to examine the ways that gender identity may intersect with market factors to produce vulnerability. Application in this setting also allows for the integration of various model enhancements, and the examination of vulnerability using a more complete formulation of the theory. Based on in-depth qualitative interviews and collages, along with examples from current marketing practice, our research shows consumer vulnerability to be a useful lens for understanding gender variant consumersâ experiences and the ways in which marketing systems can be engaged to reshape those experiences
Drugs, Devices, and Desires: A Problem-based Learning Course in the History of Medicine
Problem-based learning (PBL) is well suited for courses in the history of medicine, where multiple perspectives exist and information has to be gleaned from different sources. A student, an archivist, and a teacher offer three perspectives about a senior level course where students explored the antecedents and consequences of medical technology. Two active learning strategies were used: (a) PBL to explore the historical basis of procedures used to diagnose, prevent and treat a single disease, tuberculosis, and (b) a concurrent inquiry-based component that permitted individual exploration of other medical technologies and demonstration of learning through diverse options (book reviews, conversations, essays, archival research, oral exams). This course was highly rated by students with an overall rating of 9.5 ± 0.7 (36 students from 2008â2012)
