A Grounded Theory Exploration Of The Connection Between Stressful Life Events And Spiritual Identity For Women Leaders

Much of the research related to the leadership of women relates to development through mentorship and the gaps or disparities that exists throughout various fields and disciplines. In the United States, women continue to be underrepresented in leadership, and those in leadership continue to struggle to find the balance between their work and lives. Not only are women having different leadership experiences from their male counterparts, they are also experiencing various life events that impact their experiences as leaders, as well as the spiritual and psycho-social dimensions of their lives. The spiritual identity of women leaders who work outside of a religious context has not been explored, thus creating a gap, not only in the research, but also in the leadership practice and development of women. This dissertation examines, through a constructivist lens, the meaning that women leaders in academic medicine ascribe to their stressful life events and spiritual identity and how they connected to impact their leadership experiences. The use of constructivist grounded theory methodology resulted in the conceptualization of the Illumined Leadership Spirit. The Illumined Leadership Spirit (ILS) is a framework for understanding (a) the connection between stressful life events and spiritual identity and (b) its influences on the leadership experience and journey. ILS applies to women leaders who have embraced the impact of their spiritual identity within the milieu of their lives and leadership experiences

Stops and Stares: Street Stops, Surveillance, and Race in the New Policing

The use of proactive tactics to disrupt criminal activities, such as Terry street stops and concentrated misdemeanor arrests, are essential to the “new policing.” This model applies complex metrics, strong management, and aggressive enforcement and surveillance to focus policing on high crime risk persons and places. The tactics endemic to the “new policing” gave rise in the 1990s to popular, legal, political and social science concerns about disparate treatment of minority groups in their everyday encounters with law enforcement. Empirical evidence showed that minorities were indeed stopped and arrested more frequently than similarly situated whites, even when controlling for local social and crime conditions. In this article, we examine racial disparities under a unique configuration of the street stop prong of the “new policing” – the inclusion of non-contact observations (or surveillances) in the field interrogation (or investigative stop) activity of Boston Police Department officers. We show that Boston Police officers focus significant portions of their field investigation activity in two areas: suspected and actual gang members, and the city’s high crime areas. Minority neighborhoods experience higher levels of field interrogation and surveillance activity net of crime and other social factors. Relative to white suspects, Black suspects are more likely to be observed, interrogated, and frisked or searched controlling for gang membership and prior arrest history. Moreover, relative to their black counterparts, white police officers conduct high numbers of field investigations and are more likely to frisk/search subjects of all races. We distinguish between preference-based and statistical discrimination by comparing stops by officer-suspect racial pairs. If officer activity is independent of officer race, we would infer that disproportionate stops of minorities reflect statistical discrimination. We show instead that officers seem more likely to investigate and frisk or search a minority suspect if officer and suspect race differ. We locate these results in the broader tensions of racial profiling that pose recurring social and constitutional concerns in the “new policing.”

An Analysis of Race and Ethnicity Patterns in Boston Police Department Field Interrogation, Observation, Frisk, and/or Search Reports

The report, authored by researchers from Columbia, Rutgers and the University of Massachusetts, analyzed 200,000+ encounters between BPD officers and civilians from 2007–2010. It is intended to provide a factual basis to assess the implementation of proactive policing in Boston and how it affects Boston's diverse neighborhoods. It found racial disparities in the Boston Police Department's stop-and-frisks that could not be explained by crime or other non-race factors. Blacks during that period were the subjects of 63.3% of police-civilian encounters, although less than a quarter of the city's population is Black.

Secondary acute lymphoblastic leukemia is a distinct clinical entity with prognostic significance.

The effect of prior malignancy on the risk of developing, and prognosis of, acute lymphoblastic leukemia (ALL) is unknown. This observational study utilized the California Cancer Registry to estimate the risk of developing ALL after a prior malignancy using standardized incidence ratios (SIRs, 95% confidence intervals). ALL occurring after a malignancy with an SIR>1 (increased-risk (IR) malignancies) was considered secondary ALL (s-ALL). Adjusted hazard ratios (aHRs, 95% confidence intervals) compared the effect of s-ALL with de novo ALL on overall survival. A total of 14 481 patients with ALL were identified (1988-2012) and 382 (3%) had a known prior malignancy. Any prior malignancy predisposed patients to developing ALL: SIR 1.62 (1.45-1.79). Hematologic malignancies (SIR 5.57, 4.38-6.98) and IR-solid tumors (SIR 2.11, 1.73-2.54) increased the risk of developing ALL. s-ALL increased the risk of death compared with de novo ALL (aHR 1.38 (1.16-1.63)) and this effect was more pronounced among younger patients (age<40 years: aHR 4.80 (3.15-7.30); age⩾40 years: aHR 1.40 (1.16-1.69)) (interaction P<0.001). This population-based study demonstrates that s-ALL is a distinct entity that occurs after specific malignancies and carries a poor prognosis compared with de novo ALL, particularly among patients <40 years of age

Sustainable use and implementation of bone char as a technology for arsenic and fluoride removal

Arsenic and fluoride are key issues in the global water challenge as they exist above the World Health Organization (WHO) recommended limits of 0.010 mg/L and 1.5 mg/L, respectively, in the natural drinking water sources of many regions of the world. The suitability of using several types of bone char as a sustainable removal technology for arsenic and fluoride in remote areas of developing countries is evaluated. The results suggest that 500˚C is the ideal charring temperature for fish bone char based on removal capacity and aesthetic concerns, such as water discoloration and smell, and that there is no significant competition found when removing fluoride and arsenic simultaneously. Current water projects often fail after one to three years for a variety of reasons. Therefore, implementation strategies will also be discussed

Hippocampal neuroplasticity induced by early-life stress: functional and molecular aspects.

Whereas genetic factors contribute crucially to brain function, early-life events, including stress, exert long-lasting influence on neuronal function. Here, we focus on the hippocampus as the target of these early-life events because of its crucial role in learning and memory. Using a novel immature-rodent model, we describe the deleterious consequences of chronic early-life 'psychological' stress on hippocampus-dependent cognitive tasks. We review the cellular mechanisms involved and discuss the roles of stress-mediating molecules, including corticotropin releasing hormone, in the process by which stress impacts the structure and function of hippocampal neurons

Hippocampal neurogenesis is not enhanced by lifelong reduction of glucocorticoid levels.

Neurogenesis of dentate gyrus granule cells is generally considered to be negatively regulated by glucocorticoids. We tested the hypothesis that exposure to low plasma corticosteroid levels starting in the early postnatal period enhances granule cell proliferation rate during adulthood. Rat pups were adrenalectomized (ADX) on postnatal day 10 and were then "clamped" throughout life at low corticosterone levels via oral supplementation. Neurogenesis was determined using BrdU immunochemistry at 3 and 12 months in clamped rats as compared with age-matched, sham-operated controls. Rate of neurogenesis did not differ between the groups at either 3 or 12 months. It was significantly lower in 12-month-old compared with 3-month-old rats, despite the presence of an age-dependent increase of plasma corticosterone only in the sham-ADX rats. Granule cell layer volume, granule cell density, and granule cell degeneration (determined using apoptotic markers) were indistinguishable in the two groups, further supporting the comparable rate of neurogenesis under differing chronic glucocorticoid levels. In addition, whereas acute deprivation of plasma glucocorticoids (adrenalectomy) in adult rats evoked a burst of granule cell neurogenesis, complete elimination of these hormones (by stopping hormone supplementation) in adult, early-life ADX/clamped rats did not. These data do not support a simple inverse relationship between chronic plasma glucocorticoid levels and granule cell neurogenesis. Specifically, chronic modulation of glucocorticoid levels commencing early in life evokes additional, adaptive, and compensatory mechanisms that contribute to the regulation of granule cell proliferation

Perceptions of wildlife damage and species conservation: lessons learned from the Utah prairie dog

The Utah prairie dog (Cynomys parvidens), a federally listed threatened species, causes damage to agricultural operations, yet little incentive exists for private landowners to conserve them. Therefore, we surveyed Utah residents to identify stakeholder attitudes regarding prairie dog management. We assessed how perceptions of wildlife damage affect respondent attitudes regarding conservation among agricultural producers, rural residents, and urban residents. Higher levels of perceived wildlife damage were reported for agriculture respondents (79%) than for urban (20%) or rural (45%) respondents. Compensation for damage caused by Utah prairie dogs was supported by those engaged in agricultural production but not by rural or urban respondents. Agricultural producers, rural residents and urban residents all stated a preference for private conservation organizations to fund damage compensation rather than a government agency. Most agricultural respondents (61%) and rural respondents (64%) believed that Utah prairie dogs should be only on public lands. Some agricultural respondents (23%) thought they should be on no land. Attitudes regarding the Utah prairie dog varied, with agricultural producers being the most negative and urban respondents the most positive. The negative attitude of rural residents and agricultural producers probably results from both the damage caused by Utah prairie dogs and land-use restrictions resulting from the species being listed as threatened. Acceptance of Utah prairie dogs by private landowners may be key to the recovery of the species, and our findings suggest that alleviation of damage issues may increase landowner acceptance of conservation measures to protect Utah prairie dogs.n

Community-level Response to Habitat Structure Manipulations: An Experimental Case Study in a Tropical Ecosystem

Across the globe, environmental change is resulting in novel ecosystems that have altered habitat structure and functioning. Research is needed to understand how changes in habitat structure in these new ecosystems impact community interactions, especially when these manipulations are being proposed to reduce invasive species. We conducted an experiment in Hawaii to determine how changes in habitat structure, represented by leaf litter and understory vegetation, affect the abundance of an invasive generalist predator, the coqui frog (Eleutherodactylus coqui) and its potential prey (invertebrates). This study consisted of four treatments: two vegetation treatments (50% and 100% removal of vegetation with diameter at breast heightcm) and two leaf litter treatments (50% and 100% removal). Removal of 50% of habitat structure, either vegetation or leaf litter, was not sufficient to produce long-term changes in coqui or invertebrate densities. Only full removal of habitat structure resulted in reduced densities of coqui after four months. The abundance of leaf litter invertebrates and invertebrates flying close to the forest floor was higher in the 100% vegetation removal treatment compared to leaf litter removal treatments, and the abundance of foliage invertebrates was higher in the 100% leaf litter removal treatment compared to vegetation removal treatments. Invertebrate responses were complicated because they not only responded to the loss of habitat but also the reduction of coquis in treatments. Coquis in treatments moved to microhabitats that contained increased prey. Treatments appeared to impact coquis by removing structure needed for diurnal retreats, breeding and foraging. In summary, both the 100% removal of leaf litter or vegetation can reduce coqui densities in relatively small (20 m × 20 m) areas, even when surrounded by intact, invaded forest. This study provides greater understanding of the impact of habitat structure manipulation, a typical management employed to control an invasive frog, in a novel ecosystem
