Principles Driven Leadership: Thoughts, Observations And Conceptual Model

Leadership has as many definitions as it does books written on the subject. Discussions regarding the subject often migrate toward the differences between leadership and management. The purpose of this paper is to provide a conceptual view of leadership based on experience, observation and lessons learned. A conceptual model and a comprehensive set of principles are presented that can be used as a blueprint toward developing a sound foundation of leadership

The Manifest Destiny Of Education: Past, Present And Beyond The Boundaries Of Tradition

The generation currently in secondary schools has never known the world without the Internet, has spent thousands of hours each year interacting with video games and social media, and has high expectations for the degree of control and choices they will have regarding employment, entertainment, and the education they receive.The employers of our future graduates have undergone - and will continue to undergo - profound changes in consumer behavior and technology-based marketing and value creation, while simultaneously facing intense global competition, rapid technological advances, and dynamic markets. Employer demands for increasingly flexible, self-motivated, collaborative, communicative, creative, energetic, technology savvy employees will continue to rise. These conditions are fundamentally changing consumer and employer expectations of education and driving the need for ever greater relevance, personalization, flexibility, mobility, and meaningful and relevant outcomes. In many respects, we must work toward and plan for an evolving target and, as such, we should work to create dynamic contexts as well as learning what can change and be modified as needed

Leadership Systems Model: An Integration Of People, Process, And Behaviors In A Dynamic And Evolving Environment

Defining, observing, and measuring leadership skills, styles and approaches are far from being a new effort. Although research has provided much information regarding leadership, the classical leadership theories and models, processes, and behavioral views must be further integrated in order to provide a richer and wider view of leadership. Furthermore, organizations are not static; they are constantly changing and evolving over time. The purpose of this paper is to provide a conceptual model integrating these views using a systems level theory to understand the aggregate nature of leadership

Smoking Cessation Among Women with and at Risk for HIV: Are They Quitting?

Cigarette smoking is an important risk factor for adverse health events in HIV-infected populations. While recent US population-wide surveys report annual sustained smoking cessation rates of 3.4–8.5%, prospective data are lacking on cessation rates for HIV-infected smokers. To determine the sustained tobacco cessation rate and predictors of cessation among women with or at risk for HIV infection. Prospective cohort study. A total of 747 women (537 HIV-infected and 210 HIV-uninfected) who reported smoking at enrollment (1994–1995) in the Women’s Interagency HIV Study (WIHS) and remained in follow-up after 10 years. The participants were mostly minority (61% non-Hispanic Blacks and 22% Hispanics) and low income (68% with reported annual incomes of less than or equal to $12,000). The primary outcome was defined as greater than 12 months continuous cessation at year 10. Multivariate logistic regression was used to identify independent baseline predictors of subsequent tobacco cessation. A total of 121 (16%) women reported tobacco cessation at year 10 (annual sustained cessation rate of 1.8%, 95% CI 1.6–2.1%). Annual sustained cessation rates were 1.8% among both HIV-positive and HIV-negative women (p = 0.82). In multivariate analysis, the odds of tobacco cessation were significantly higher in women with more years of education (p trend = 0.02) and of Hispanic origin (OR = 1.87, 95% CI = 1.4–2.9) compared to Black women. Cessation was significantly lower in current or former illicit drug users (OR = 0.42 95% CI = 0.24–0.74 and OR = 0.65, 95% CI = 0.49–0.86, respectively, p trend = 0.03) and women reporting a higher number of cigarettes per day at baseline (p trend < 0.001). HIV-infected and at-risk women in this cohort have lower smoking cessation rates than the general population. Given the high prevalence of smoking, the high risk of adverse health events from smoking, and low rates of cessation, it is imperative that we increase efforts and overcome barriers to help these women quit smoking

Tenofovir Use and Urinary Biomarkers Among HIV-Infected Women in the Women's Interagency HIV Study (WIHS)

BackgroundTenofovir (TDF) has been associated with renal tubular injury. Biomarkers that signal early tubular dysfunction are needed because creatinine rise lags behind TDF-associated kidney dysfunction. We examined several urinary biomarkers to determine if rises accompanying TDF initiation preceded creatinine changes.MethodsThree urinary biomarkers of tubular impairment--neutrophil gelatinase-associated lipocalin (NGAL), N-acetyl-β-D-glucosaminidase (NAG), and β-2-microglobulin (β2MG)--were measured across 3 time points (one pre-TDF visit and 2 post-TDF visits) in 132 HIV-positive women from the Women's Interagency HIV Study. Women initiating highly active antiretroviral therapy (HAART) containing TDF were propensity score matched to women initiating HAART without TDF and women not on HAART.ResultsThere were no differences between groups for NGAL or NAG, but β2MG was 19 times more likely to be elevated among TDF users at the second post-TDF visit compared with non-TDF users at the pre-TDF visit (P < 0.01). History of proteinuria was associated with elevated NGAL (P < 0.01). Factors associated with elevated NAG were glomerular filtration rate <60 mL/minute, history of proteinuria, hepatitis C (P < 0.01 for all), and diabetes mellitus (P = 0.05). Factors associated with increased odds of elevated β2MG were HIV RNA >100,000 copies/mL, hepatitis C, boosted protease inhibitor use, and glomerular filtration rate <60 mL/minute (P ≤ 0.01 for all).Conclusionsβ2MG levels are elevated in women on TDF, indicating probable early renal dysfunction. Biomarker elevation is additionally associated with baseline chronic kidney disease, uncontrolled viremia, and boosted protease inhibitor use. Future studies are needed to explore urinary biomarker thresholds in identifying treated HIV-infected individuals at risk for renal dysfunction

Medicinal and Recreational Marijuana Use Among HIV-Infected Women in the Women's Interagency HIV Study (WIHS) Cohort, 1994–2010

BackgroundDespite the major benefits of effective antiretroviral therapy on HIV-related survival, there is an ongoing need to help alleviate medication side effects related to antiretroviral therapy use. Initial studies suggest that marijuana use may reduce HIV-related symptoms, but medical marijuana use among HIV-infected individuals has not been well described.MethodsThe authors evaluated trends in marijuana use and reported motivations for use among 2776 HIV-infected women in the Women's Interagency HIV Study between October 1994 and March 2010. Predictors of any and daily marijuana use were explored in multivariate logistic regression models clustered by person using generalized estimating equation. In 2009, participants were asked if their marijuana use was medical, "meaning prescribed by a doctor," or recreational, or both.ResultsOver the 16 years of this study, the prevalence of current marijuana use decreased significantly from 21% to 14%. In contrast, daily marijuana use almost doubled from 3.3% to 6.1% of all women and from 18% to 51% of current marijuana users. Relaxation, appetite improvement, reduction of HIV-related symptoms, and social use were reported as common reasons for marijuana use. In 2009, most marijuana users reported either purely medicinal use (26%) or both medicinal and recreational usage (29%). Daily marijuana use was associated with higher CD4 cell count, quality of life, and older age. Demographic characteristics and risk behaviors were associated with current marijuana use overall but were not predictors of daily use.ConclusionsThis study suggests that both recreational and medicinal marijuana use are relatively common among HIV-infected women in the United States

Association of cervical precancer with human papillomavirus types other than 16 among HIV co-infected women.

BackgroundHIV-seropositive women face high risk for infection with oncogenic human papillomavirus (oncHPV) types, abnormal Pap test results, and precancer, but cervical cancer risk is only modestly increased. Human papillomavirus (HPV)16 is highly oncogenic but only weakly associated with HIV status and immunosuppression, suggesting HPV16 may have a greater innate ability to evade host immune surveillance than other oncHPV types, which in turn should result in a greater relative increase in the prevalence of other oncHPV types among women with cervical precancer.ObjectiveWe sought to assess whether the underrepresentation of HPV16 among HIV-seropositive relative to HIV-seronegative women remains among those with cervical precancers.Study designHIV-seropositive and HIV-seronegative women in the Women's Interagency HIV Study were screened for cervical intraepithelial neoplasia (CIN) grade ≥3 (CIN3(+)). DNA from >40 HPV types was detected by polymerase chain reaction in cervicovaginal lavage specimens obtained at the visit at which CIN3(+) was diagnosed.ResultsHPV16 was detected in 13 (62%) of 21 HIV-seronegative women with CIN3(+) but only 44 (29%) of 154 HIV-seropositive women with CIN3(+) (P = .01). The lower prevalence of HPV16 in CIN3(+) among HIV-seropositive women persisted after controlling for covariates (odds ratio [OR], 0.25; 95% confidence interval [CI], 0.08-0.78). The prevalence of other members of the HPV16-related alpha-9 oncHPV clade as a group was similar in HIV-infected and uninfected women with CIN3(+) (OR, 1.02; 95% CI, 0.53-1.94). The prevalence of non-alpha-9 oncHPV types was increased in HIV-seropositive vs HIV-seronegative women with CIN3(+) (OR, 3.9; 95% CI, 1.3-11.8).ConclusionThe previously demonstrated increase in CIN3(+) incidence among HIV-seropositive women is associated with lower HPV16 and higher non-alpha-9 oncHPV prevalence. This is consistent with prior reports that HIV has a weak effect on infection by HPV16 relative to other oncHPV and supports use of nonavalent HPV vaccine in HIV-seropositive women
