But weâre not laughing: White male college studentsâ racial joking and what this says about âpost-racialâ discourse
YPAR, Critical Whiteness, and Generative Possibilities. A Response to âSam and Cristina: A Dialogue Between a High School Teacher and Student about the Commoditization of People of Colorâ
In this response to the article by Tanner and Corrie, the authors provide three critiques of the methodology and theoretical framing of the study with the hopes of informing future scholarship and practice. Specifically, the three critiques addressed in this paper include the integration of CWS frameworks and YPAR methodology, the application and description of CWS and YPAR frameworks, and the role of power in the relationship between educator and student that served as the central medium for the study
Arizona Uncertainty: Arbitrary Barriers in Accessing Institutional Need-Based Financial Aid
Established in 2008, the Arizona Assurance Scholars Program (AASP) channeled institutional need-based aid to in-state, low-income students. Rapidly growing costs prompted three changes to the AASP eligibility requirements in 2011. We examined how these new requirementsâa 3.0 or higher high school grade point average and the submission of the Free Application of Federal Student Aid (FAFSA) and admission paperwork by March 1âwould affect the gender, racial, and socioeconomic composition of the programâs first three cohorts if they were in effect. Results revealed disproportionate impacts on racial and ethnic minorities and widened gender gaps. Male, Latina/o, and Native American students would be at statistically greater risk for ineligibility relative to female, Asian, and White students. These findings signal the need to model the consequences of policy change, particularly when it reduces college access and undermines the equity of institutional need-based financial aid programs
Catalytic Intermolecular Hetero-Dehydro-DielsâAlder Cycloadditions: Regio- and Diasteroselective Synthesis of 5,6-Dihydropyridin-2-ones
A novel catalyzed intermolecular heterodehydro-DielsâAlder reaction between pushâpull 1,3-dien-5-ynes and aldimines or silylaldimines is reported. The sequence is promoted both by gold(I) or silver(I) catalysts and leads to the diastereo- and regioselective formation of 5,6-dihydropyridin-2-onesMICINN (Spain) (grants CTQ2009-09949, CTQ2010-16790, PTA2008-1524-P contract to J.M.F.-G. and Ramon y Cajal postdoctoral contract to M.A.F.-R.) and FICYT (project IB08-088)This document is the Accepted Manuscript version of a Published Work that appeared in final form in

Energy Management of People in Organizations: A Review and Research Agenda
Although energy is a concept that is implied in many motivational theories, is hardly ever explicitly mentioned or researched. The current article first relates theories and research findings that were thus far not explicitly related to energy. We describe theories such as flow, subjective well-being, engagement and burn-out, and make the link with energy more explicit. Also, we make a first link between personality characteristics and energy, and describe the role of leadership in unleashing followersâ energy. Following, we identify how the topic of energy management can be profitably incorporated in research from a scientific as well as a practitioner viewpoint. Finally, we describe several interventions to enhance energy in individuals and organizations
A pair of Sub-Neptunes transiting the bright K-dwarf TOI-1064 characterised with CHEOPS
Funding: TGW, ACC, and KH acknowledge support from STFC consolidated grant numbers ST/R000824/1 and ST/V000861/1, and UKSA grant ST/R003203/1.We report the discovery and characterization of a pair of sub-Neptunes transiting the bright K-dwarf TOI-1064 (TIC 79748331), initially detected in the Transiting Exoplanet Survey Satellite (TESS) photometry. To characterize the system, we performed and retrieved the CHaracterising ExOPlanets Satellite (CHEOPS), TESS, and ground-based photometry, the High Accuracy Radial velocity Planet Searcher (HARPS) high-resolution spectroscopy, and Gemini speckle imaging. We characterize the host star and determine Teff,â=4734±67Kâ , Râ=0.726±0.007Rââ , and Mâ=0.748±0.032Mââ . We present a novel detrending method based on point spread function shape-change modelling and demonstrate its suitability to correct flux variations in CHEOPS data. We confirm the planetary nature of both bodies and find that TOI-1064 b has an orbital period of Pb = 6.44387 ± 0.00003 d, a radius of Rb = 2.59 ± 0.04 Râ, and a mass of Mb=13.5+1.7â1.8 Mâ, whilst TOI-1064 c has an orbital period of Pc=12.22657+0.00005â0.00004 d, a radius of Rc = 2.65 ± 0.04 Râ, and a 3Ï upper mass limit of 8.5 Mâ. From the high-precision photometry we obtain radius uncertainties of âŒ1.6 per cent, allowing us to conduct internal structure and atmospheric escape modelling. TOI-1064 b is one of the densest, well-characterized sub-Neptunes, with a tenuous atmosphere that can be explained by the loss of a primordial envelope following migration through the protoplanetary disc. It is likely that TOI-1064 c has an extended atmosphere due to the tentative low density, however further radial velocities are needed to confirm this scenario and the similar radii, different masses nature of this system. The high-precision data and modelling of TOI-1064 b are important for planets in this region of massâradius space, and it allow us to identify a trend in bulk densityâstellar metallicity for massive sub-Neptunes that may hint at the formation of this population of planets.Publisher PDFPeer reviewe
International Lower Limb Collaborative (INTELLECT) study: a multicentre, international retrospective audit of lower extremity open fractures
International lower limb collaborative (INTELLECT) study: a multicentre, international retrospective audit of lower extremity open fractures
Trauma remains a major cause of mortality and disability across the world1, with a higher burden in developing nations2. Open lower extremity injuries are devastating events from a physical3, mental health4, and socioeconomic5 standpoint. The potential sequelae, including risk of chronic infection and amputation, can lead to delayed recovery and major disability6. This international study aimed to describe global disparities, timely intervention, guideline-directed care, and economic aspects of open lower limb injuries
