The myth of charismatic leadership and fantasy rhetoric of crypto-charismatic memberships

This study will analyze the relationship between myth and the fantasy rhetoric of charismatic leadership by employing Fantasy Theme Analysis to examine the pervasive discourses invoking this enduring folk belief. Fantasies of the Charismatic Superhero are explored within the popular leadership treatises of successful “management gurus” and in our popular culture entertainments. The rhetorical visions of Stephen Covey’s “Principle-Centered Leadership,” Jim Collins’ “Level 5 Leadership,” and Manz and Sims\u27 “SuperLeadership” are examined for their displacement of charismatic leadership in favor of the empowered crypto-charisma of self-leading memberships. Findings suggest “empowerment” rhetorics, like the rhetorical visions championed by many populist “gurus,” bear striking similarities to the fantasy script of charisma and tacitly champion mythic culturetypes that are variations on known routinizations of charismatic leadership: the Ubermensch Prophet, the Messianic Prince, the Servant Superhero, or Technocratic Superteams

Examination of asynchronous volumetric and frequency communication patterns in online courses and their impact on adult learner satisfaction

The purpose of this study was to investigate the relationship of online discussion board interactions of adult learners and their satisfaction with their experience. Specifically, this study\u27s objectives were to examine the asynchronous volumetric and frequency textual communication patterns through online discussion boards and the association to adult learner satisfaction for 102 electronically surveyed adult learners at a mid-western university during the 2005-2006 academic year. Highly reliable (Cronbach alpha = 0.97) and valid data were collected from a learner satisfaction form developed specifically for the outcome variable o f this study. Exploratory factor analysis provided evidence that the data collected from the form were asymmetrically sub-structured into four distinct factors. Communication constructs of momentum, force, and energy were created from physical parameters and determined to be the main predictor variables in this study. The communication constructs were significantly related to the outcome of learner satisfaction and collectively constituted the structural core of this study’s model as determined by correlations and linear regression modeling. Moderator variables of learner prior experience and learner prior satisfaction were found to create a highprecision model of asynchronous volumetric and frequency communication patterns and learner satisfaction through correlations and interaction effects in regression analysis. The study provides core and high-precision models that link asynchronous textual communication for discussion boards in online courses to adult learner satisfaction

Dedicated outreach service for hard to reach patients with tuberculosis in London: observational study and economic evaluation.

OBJECTIVE: To assess the cost effectiveness of the Find and Treat service for diagnosing and managing hard to reach individuals with active tuberculosis. DESIGN: Economic evaluation using a discrete, multiple age cohort, compartmental model of treated and untreated cases of active tuberculosis. SETTING: London, United Kingdom. Population Hard to reach individuals with active pulmonary tuberculosis screened or managed by the Find and Treat service (48 mobile screening unit cases, 188 cases referred for case management support, and 180 cases referred for loss to follow-up), and 252 passively presenting controls from London's enhanced tuberculosis surveillance system. MAIN OUTCOME MEASURES: Incremental costs, quality adjusted life years (QALYs), and cost effectiveness ratios for the Find and Treat service. RESULTS: The model estimated that, on average, the Find and Treat service identifies 16 and manages 123 active cases of tuberculosis each year in hard to reach groups in London. The service has a net cost of £1.4 million/year and, under conservative assumptions, gains 220 QALYs. The incremental cost effectiveness ratio was £6400-£10,000/QALY gained (about €7300-€11,000 or $10,000-$16 000 in September 2011). The two Find and Treat components were also cost effective, even in unfavourable scenarios (mobile screening unit (for undiagnosed cases), £18,000-£26,000/QALY gained; case management support team, £4100-£6800/QALY gained). CONCLUSIONS: Both the screening and case management components of the Find and Treat service are likely to be cost effective in London. The cost effectiveness of the mobile screening unit in particular could be even greater than estimated, in view of the secondary effects of infection transmission and development of antibiotic resistance

Thermorheological Properties Near the Glass Transition of Oligomeric Poly(methyl methacrylate) Blended with Acrylic Polyhedral Oligomeric Silsesquioxane Nanocages

Submitted to Rheologica ActaTwo distinct oligomeric species of similar mass and chemical functionality (Mw ≈ 2,000 g/mol), one a linear methyl methacrylate oligomer (radius of gyration Rg ≈ 1.1 nm) and the other a hybrid organic-inorganic polyhedral silsesquioxane nanocage (methacryl-POSS, r ≈ 1.0 nm), were subjected to thermal and rheological tests to compare the behaviors of these geometrically dissimilar molecules over the entire composition range. The glass transition temperatures of the blends varied monotonically between the glass transition temperatures of the pure oligomer (Tg = â47.3°C) and the pure POSS (Tg = â61.0°C). Blends containing high POSS contents (with volume fraction φ_POSS ⥠0.90) exhibited enhanced enthalpy relaxation in DSC measurements, and the degree of enthalpy relaxation was used to calculate the kinetic fragility indices m of the oligomeric MMA (m = 59) and the POSS (m = 74). The temperature dependences of the viscosities were fitted by the free volume-based WLF-VFT framework and a dynamic scaling relation. The calculated values of the fragility from the WLF-VFT fits were similar for the POSS (m = 82) and for the oligomer (m = 76), and the dynamic scaling exponent was similar for the oligomeric MMA and the POSS. Within the range of known fragilities for glass-forming liquids, the temperature dependence of the viscosity was found to be similarly fragile for the two species. The difference in shape of the nanocages and oligomer chains is unimportant in controlling the glass-forming properties of the blends at low volume fractions ( φPOSS < 0.20); however, at higher volume fractions, adjacent POSS cages begin to crowd each other, leading to an increase in the fractional free volume at the glass transition temperature and the observed enhanced enthalpy relaxation in DSC.AFOSR (DURINT Program

A Comparison of White and African American Outcomes from a Three-Arm, Randomized, Phase III Multicenter Trial of Advanced or Metastatic Non-small Cell Lung Cancer

PURPOSE: To investigate the effect of race on the efficacy and safety of standard chemotherapy doublet regimens in African American patients, we conducted a subgroup analysis of a phase III randomized trial. PATIENTS AND METHODS: Chemonaïve patients with a performance status of 0 or 1 and stage IIIB or IV non-small cell lung cancer were randomized to arm A: gemcitabine 1000 mg/m2 on days 1 and 8 plus carboplatin area under the curve 5.5 on day 1; arm B: the same schedule of gemcitabine plus paclitaxel 200 mg/m2 on day 1; or arm C: paclitaxel 225 mg/m2 on day 1 plus carboplatin area under the curve 6.0 on day 1. Cycles were repeated every 21 days up to 6. A site selection tool identified institutions with potential to recruit a minority population. Outcome and toxicity data of white and African American patients were compared. RESULTS: Of 1135 total patients, 972 were white (85.6%) and 138 were African American (12.2%). Median survival was 8.3 months for white patients (95% confidence interval [CI]: 7.7-9.3) and 9.1 months for African American patients (95% CI: 8.2-11.1). Response rates were 29.1 and 29.0%, respectively. Rates of grade 3 or 4 toxicities were comparable. Among African Americans, median survival was 7.2 months (95% CI: 5.1-10.1) for gemcitabine-carboplatin (n = 47), 10.5 months (95% CI: 7.1-15.4) for gemcitabine-paclitaxel (n = 42), and 10.2 months (95% CI: 8.5-13.2) for paclitaxel-carboplatin (n = 49). CONCLUSION: Whites and African Americans had similar outcomes, although there was some variability in survival among African Americans across the three treatment groups

Challenges of drug resistance in the management of pancreatic cancer

The current treatment of choice for metastatic pancreatic cancer involves single agent gemcitabine or combination of gemcitabine with capecitabine and erlotinib (tyrosine kinase inhibitor). Only 25-30% of patients respond to this treatment and patients who do respond initially ultimately exhibit disease progression. Median survival for pancreatic cancer patients has reached a plateau due to inherent and acquired resistance to these agents. Key molecular factors implicated in this resistance include: deficiencies in drug uptake, alteration of drug targets, activations of DNA repair pathways, resistance to apoptosis, and the contribution of the tumor microenvironment. Moreover, for newer agents including tyrosine kinase inhibitors, over expression of signaling proteins, mutations in kinase domains, activation of alternative pathways, mutations of genes downstream of the target, and/or amplification of the target represent key challenges for treatment efficacy. Here we will review the contribution of known mechanisms and markers of resistance to key pancreatic cancer drug treatments
