Conceptualising and measuring fan identity using stakeholder theory

Research question: Building on identity theory and stakeholder theory, this study explores the concept of fan identity based on self-perceived levels of power, urgency, internal and external legitimacy, and examines their effects on behavioural intentions.Research methods: Data were collected from professional football fans (n = 532). A confirmatory factor analysis analysed the psychometric properties of the constructs, and a subsequent structural equation model examined the effects of fan identity on three behavioural intention measures.Results and findings: The results indicate acceptable psychometric properties of the multidimensional construct of fan identity composed of power, urgency, internal legitimacy and external legitimacy. Power and internal legitimacy were significantly related to the intentions to attend more games and to purchase merchandise, with internal legitimacy also influencing intentions to recommend games to others.Implications: This study provides the first exploration of fan identity as a multidimensional construct. The findings provide sport managers with useful insights on how to measure fan identity. This study serves as a catalyst for future research to understand the linkages between professional sport teams and their fans

Poverty in Buffalo: Causes, Impacts, Solutions

This policy report examines the scope of poverty and inequality in Buffalo-Niagara, the causes of poverty, and its impacts across health, homelessness, education, and more. It features the insights of testifiers and commissioners from the Buffalo Truth Commission on Poverty, convened on January 25, 2018 by the Coalition for Economic Justice, the WNY Poor People\u27s Campaign, and the New York State Truth Commission on Poverty. The report concludes with solutions from the local to the federal level

Advanced Transport Operating System (ATOPS) Flight Management/Flight Controls (FM/FC) software description

The flight software developed for the Flight Management/Flight Controls (FM/FC) MicroVAX computer used on the Transport Systems Research Vehicle for Advanced Transport Operating Systems (ATOPS) research is described. The FM/FC software computes navigation position estimates, guidance commands, and those commands issued to the control surfaces to direct the aircraft in flight. Various modes of flight are provided for, ranging from computer assisted manual modes to fully automatic modes including automatic landing. A high-level system overview as well as a description of each software module comprising the system is provided. Digital systems diagrams are included for each major flight control component and selected flight management functions

Leadership styles used by senior medical leaders : patterns, influences and implications for leadership development

Purpose: Clinician leadership is important in healthcare delivery and service development. The use of different leadership styles in different contexts can influence individual and organisational effectiveness. The purpose of this study was to determine the predominant leadership styles used by medical leaders and factors influencing leadership style use. Design: A mixed methods approach was used, combining a questionnaire distributed electronically to 224 medical leaders in acute hospital trusts with in depth ‘critical incident’ interviews with six medical leaders. Questionnaire responses were analysed quantitatively to determine firstly the overall frequency of use of six predefined leadership styles, and secondly, individual leadership style based on a consultative/decision-making paradigm. Interviews were analysed thematically using both a confirmatory approach with predefined leadership styles as themes; and also an inductive grounded theory approach exploring influencing factors. Findings: Leaders used a range of styles, the predominant styles being democratic, affiliative and authoritative. Although leaders varied in their decision-making authority and consultative tendency, virtually all leaders showed evidence of active leadership. Organisational culture, context, individual propensity and ‘style history’ emerged during the inductive analysis as important factors in determining use of leadership styles by medical leaders. Implications: The outcomes of this evaluation are useful for leadership development at the level of the individual, organisation and wider NHS. Originality/value: This study adds to the very limited evidence base on patterns of leadership style use in medical leadership and reports a novel conceptual framework of factors influencing leadership style use by medical leaders.</p

Don Juan Pond, Antarctica: Near-surface CaCl₂-brine feeding Earth's most saline lake and implications for Mars

The discovery on Mars of recurring slope lineae (RSL), thought to represent seasonal brines, has sparked interest in analogous environments on Earth. We report on new studies of Don Juan Pond (DJP), which exists at the upper limit of ephemeral water in the McMurdo Dry Valleys (MDV) of Antarctica, and is adjacent to several steep-sloped water tracks, the closest analog for RSL. The source of DJP has been interpreted to be deep groundwater. We present time-lapse data and meteorological measurements that confirm deliquescence within the DJP watershed and show that this, together with small amounts of meltwater, are capable of generating brines that control summertime water levels. Groundwater input was not observed. In addition to providing an analog for RSL formation, CaCl₂ brines and chloride deposits in basins may provide clues to the origin of ancient chloride deposits on Mars dating from the transition period from “warm/wet” to “cold/dry” climates

PI3K/AKT/mTOR inhibition in combination with doxorubicin is an effective therapy for leiomyosarcoma.

BackgroundLeiomyosarcoma (LMS) is a common type of soft tissue sarcoma that responds poorly to standard chemotherapy. Thus the goal of this study was to identify novel selective therapies that may be effective in leiomyosarcoma by screening cell lines with a small molecule library comprised of 480 kinase inhibitors to functionally determine which signalling pathways may be critical for LMS growth.MethodsLMS cell lines were screened with the OICR kinase library and a cell viability assay was used to identify potentially effective compounds. The top 10 % of hits underwent secondary validation to determine their EC50 and immunoblots were performed to confirm selective drug action. The efficacy of combination drug therapy with doxorubicin (Dox) in vitro was analyzed using the Calcusyn program after treatment with one of three dosing schedules: concurrent treatment, initial treatment with a selective compound followed by Dox, or initial treatment with Dox followed by the selective compound. Single and combination drug therapy were then validated in vivo using LMS xenografts.ResultsCompounds that targeted PI3K/AKT/mTOR pathways (52 %) were most effective. EC50s were determined to validate these initial hits, and of the 11 confirmed hits, 10 targeted PI3K and/or mTOR pathways with EC50 values &lt;1 μM. We therefore examined if BEZ235 and BKM120, two selective compounds in these pathways, would inhibit leiomyosarcoma growth in vitro. Immunoblots confirmed on-target effects of these compounds in the PI3K and/or mTOR pathways. We next investigated if there was synergy with these agents and first line chemotherapy doxorubicin (Dox), which would allow for earlier introduction into patient care. Only combined treatment of BEZ235 and Dox was synergistic in vitro. To validate these findings in pre-clinical models, leiomyosarcoma xenografts were treated with single agent and combination therapy. BEZ235 treated xenografts (n = 8) demonstrated a decrease in tumor volume of 42 % whereas combining BEZ235 with Dox (n = 8) decreased tumor volume 68 % compared to vehicle alone.ConclusionsIn summary, this study supports further investigation into the use of PI3K and mTOR inhibitors alone and in combination with standard treatment in leiomyosarcoma patients
