    This research paper can be segmented into three parts. The first segment aims to understand the concept of sustainability by looking at the evolution of the definition over time, as well as relevant scientifically founded frameworks that explain the root causes that have generated our current unsustainable state of society. e second segment looks at stories of enterprises that have managed to successfully integrate sustainability into their business model to develop sustainable on-going operations that have bene ted all stakeholders involved equitably. The third segment is an initial assessment of the Peruvian alpaca wool sector to demonstrate some of the challenges entrepreneurs face to develop a sustainable enterprise, as well as probe applicability of the tools we developed from our work in the previous two segments. Findings from the first and second segments of this paper served as fundamental basis for the development of our output: The Bottom-up pyramid model, and the Sustainability guiding principles. The Bottom-up pyramid model visually represents our understanding of the required components to develop a sustainable enterprise from the ground up. The main takeaway of this representation is that a sustainable enterprise should be founded on knowledge from the incumbent community home to a natural resource, and that business development and growth should be bottom-up, taking into account community concerns and points of view. e Sustainability guiding principles are a list of guidelines entrepre- neurs can use to get a better understanding of some of the challenges they may face when attempting to develop a sustainable enterprise in a rural community. Ultimately, these instruments are aimed at providing guidance to leaders and entrepreneurs who want to establish business models with sustainable operations that do not compromise the long- term welfare of a natural resource and the community reliant on it. e last segment of this paper aims to probe the tools we developed to iterate their practicality and relevance with a contemporary real-world situation. We chose the alpaca wool sector in Peru because it is representative of the types of hurdles leaders could face when attempting to initiate a sustainable enterprise. Additionally, one of the team’s researchers had access to stakeholders in this sector, which provided primary research to complement and corroborate our literary review. is assessment is an initial step that needs further validation with more pragmatic information and on-site data for a more detailed analysis of the issues hindering specific communities in the Andes

    O grande arco de Teach For America: A análise textual da obra de Wendy Kopp usando a teoria racial crítica

    Get PDF
    We read and analyzed 165,000 words and uncover a series of counter-stories buried within a textual corpus, authored by Teach For America (TFA) founder Wendy Kopp (Kopp, 1989, 2001; Kopp Farr, 2011), that offers insight into the forms of racism endemic to Teach For America. All three counter-stories align with a critical race theory (CRT) framework.  Specifically, we answer the following questions:  What evidence of institutional and epistemological racism is exposed by a CRT textual analysis of TFA’s founding document and later works by Wendy Kopp?  To what extent has TFA appropriated the language of culturally relevant pedagogy, while advancing an uninterrogated neoliberal ideology? And, to what extent does TFA’s contribution to a “culture of achievement” (Kopp Farr, 2011) constitute an actual “poverty of culture” (Ladson-Billings, 2006a) that enacts real harms on communities of color? Leímos y analizamos 165.000 palabras escritas por Wendy Kopp (Kopp, 1989, 2001; Kopp y Farr, 2011) la fundadora de Teach For America (TFA) y descubrimos una serie de contra-historias enterradas dentro de un corpus textual, que ofrecen información sobre formas de racismo endémicas en Teach For America. Tres contra-relatos se alinean con el marco de la teoría crítica de la raza (CRT). Específicamente, respondemos a las siguientes preguntas: ¿Qué evidencia de racismo institucional y epistemológico se exponen por un análisis textual CRT del documento fundacional de TFA y obras de Wendy Kopp? ¿Hasta qué punto TFA se ha apropiado del lenguaje de la pedagogía culturalmente relevante, mientras se avanza una ideología neoliberal sin interrogarla? Y, ¿en qué medida la contribución de TFA a una "cultura del logro" (Kopp y Farr, 2011) constituyen un "empobrecimiento cultural" (Ladson-Billings, 2006a), que permite daños reales en comunidades de color?Lemos e analisamos 165.000 palavras escritas por Wendy Kopp (Kopp, 1989, 2001; Kopp e Farr, 2011) a fundadora do Teach For America (TFA) e descobrimos uma série de contra-narrativas enterradas dentro de um corpus, que oferece informações sobre as formas de racismo endêmico em Teach For America.

    Active Cognitive Lifestyle Associates with Cognitive Recovery and a Reduced Risk of Cognitive Decline

    Get PDF
    Education and lifestyle factors linked with complex mental activity are thought to affect the progression of cognitive decline. Collectively, these factors can be combined to create a cognitive reserve or cognitive lifestyle score. This study tested the association between cognitive lifestyle score and cognitive change in a population-based cohort of older persons from five sites across England and Wales. Data came from 13,004 participants of the Medical Research Council Cognitive Function and Ageing Study who were aged 65 years and over. Cognition was assessed at multiple waves over 16 years using the Mini-Mental State Examination. Subjects were grouped into four cognitive states (no impairment, slight impairment, moderate impairment, severe impairment) and cognitive lifestyle score was assessed as a composite measure of education, mid-life occupation, and current social engagement. A multi-state model was used to test the effect of cognitive lifestyle score on cognitive transitions. Hazard ratios for cognitive lifestyle score showed significant differences between those in the upper compared to the lower tertile with a more active cognitive lifestyle associating with: a decreased risk of moving from no to slight impairment (0.58, 95% CI (0.45, 0.74)); recovery from a slightly impaired state back to a non-impaired state (2.93 (1.35, 6.38)); but an increased mortality risk from a severely impaired state (1.28 (1.12, 1.45)). An active cognitive lifestyle is associated with a more favorable cognitive trajectory in older persons. Future studies would ideally incorporate neuroradiological and neuropathological data to determine if there is causal evidence for these associations

    Performance and reference data in the jump squat at different relative loads in elite sprinters, rugby players, and soccer players

    The aims of this study were to compare the outcomes and provide reference data for a set of barbell mechanical parameters collected via a linear velocity transducer in 126 male sprinters (n = 62), rugby players (n = 32), and soccer players (n = 32). Bar-velocity, bar-force, and bar-power outputs were assessed in the jump-squat exercise with jump-squat height determined from bar-peak velocity. The test started at a load of 40% of the athletes\u27 body mass (BM), and a load of 10% of BM was gradually added until a clear decrement in the bar power was observed. Comparisons of bar variables among the three sports were performed using a one-way analysis of variance. Relative measures of bar velocity, force, and power, and jump-squat height were significantly higher in sprinters than in rugby (difference ranging between 5 and 35%) and soccer (difference ranging between 5 and 60%) players across all loads (40-110% of BM). Rugby players exhibited higher absolute bar-power (mean difference = 22%) and bar-force (mean difference = 16%) values than soccer players, but these differences no longer existed when the data were adjusted for BM (mean difference = 2.5%). Sprinters optimized their bar-power production at significantly greater relative loads (%BM) than rugby (mean difference = 22%) and soccer players (mean difference = 25%); nonetheless, all groups generated their maximum bar-power outputs at similar bar velocities. For the first time, we provided reference values for the jump-squat exercise for three different bar-velocity measures (i.e., mean, mean propulsive, and peak velocity) for sprinters, rugby players, and soccer players, over a wide range of relative loads. Practitioners can use these reference values to monitor their athletes and compare them with top-level sprinters and team-sport players
