To advance efforts for assessing professional development in undergraduate physiology coursework, our study investigates how students described aspects of course structure in an introductory physiology course in relation to transferable skills for other professional pursuits. The study context was a large-enrollment undergraduate physiology course that was redesigned to use weekly classroom assessment techniques and active learning. Based on the theoretical framework of transfer of learning and the principles of Universal Design for Learning (UDL) informed by critical disability theory, we conducted a qualitative inquiry of written responses through deductive and inductive content analysis. We found that the vast majority of students described how aspects of course structure supported their transferable skill development, often highlighting the weekly rhythm: Muddy Mondays, Working Wednesdays, and Freaky Fridays. Furthermore, students provided evidence of applying strategies from a single course to other courses, in alignment with UDL principles as well as the Physiology Majors Interest Group (P-MIG) career competencies. Our study offers a comprehensive overview of how multiple components of course structure can support transferable skill development, with implications for education researchers who assess and instructors who apply active learning strategies in instructional design for undergraduate physiology courses.NEW & NOTEWORTHY In alignment with Universal Design for Learning principles as well as the Physiology Majors Interest Group (P-MIG) career competencies, this study offers a comprehensive overview of how multiple components of course structure can support transferable skill development, with implications for education researchers who assess and instructors who apply active learning strategies in instructional design for undergraduate physiology courses.

This phenomenological reflection explores the meaning and significance embedded in lesbian hands. Hands are a site that bears the inscription of difference and deviance on our bodies, but our freaky (and freakishly talented) hands should also be reclaimed as a site of specifically lesbian power and erotic significance. Combining personal and cultural musings,Wednesday celebrates lesbian hands as symbols of lesbian strength, independence, uniqueness, talent, and desire.

Short Message Service (SMS) remains one of the most popular communication channels since its introduction in 2G cellular networks. In this paper, we demonstrate that merely receiving silent SMS messages regularly opens a stealthy side-channel that allows other regular network users to infer the whereabouts of the SMS recipient. The core idea is that receiving an SMS inevitably generates Delivery Reports whose reception bestows a timing attack vector at the sender. We conducted experiments across various countries, operators, and devices to show that an attacker can deduce the location of an SMS recipient by analyzing timing measurements from typical receiver locations. Our results show that, after training an ML model, the SMS sender can accurately determine multiple locations of the recipient. For example, our model achieves up to 96% accuracy for locations across different countries, and 86% for two locations within Belgium. Due to the way cellular networks are designed, it is difficult to prevent Delivery Reports from being returned to the originator making it challenging to thwart this covert attack without making fundamental changes to the network architecture.
Transplanting the existing e-home healthcare system to source-limited embedded-link device for home-use health monitoring, intelligent medical diagnosis and wireless transmission is attractive. Yet, constrains of portable storage, computing and transmission promote the need of data compression for such applications. Existing compression techniques are mostly desktop-computer-based and computation-consuming, making them unsuitable for mobile device. To tackle such a bottleneck problem, this paper addresses an effective low-complexity multi-vital-signs compression technique based on orthogonal polynomial decomposition (OPD) algorithm using Hermite functions. The technique is proposed and operated on the designated healthcare system with optimized parameters. Validated and tested with cardiovascular disease (CVD) diagnosis based on sphygmogram both experimentally and clinically, the proposed technique achieves comparable good performance with distortion less than 2% and compression ratio up to 6, and preserves significant pathological features of multi-vital-signs for clinical diagnosis. The proposed technique is highly robust even for freaky and pathological signals. In addition, the compressed results reflecting morphological features can be directly adapted to the subsequent medical analysis without further decompression.
Despite the growing popularity of MDMA (ecstasy/molly) among African Americans, their motives for using the drug are still largely unknown. The purpose of this study was to identify and describe the most salient motivations for using MDMA among this understudied population. In-depth interviews (n = 15) were conducted with a sample of African American young adults in Southwest Florida between August 2014 and November 2015. The primary motivations for using MDMA included: (1) altering the effects of marijuana and alcohol; (2) lasting longer sexually; (3) enhancing sexual pleasure; and (4) facilitating "freaky" sexual experiences. This is the first study to directly examine MDMA motivations specifically among African American drug users, and findings shed light on why some African Americans use MDMA. A better understanding of why African Americans use this drug should help to inform prevention and harm-reduction efforts. Study findings show the need for health messages that include the potential consequences of mixing MDMA with other drugs, and engaging in high-risk sexual behaviors after taking MDMA. These data contrast with motivations (e.g., introspection, self-enlightenment, getting into the music) commonly reported among groups of largely White MDMA users, suggesting that interventions tailored specifically for African American users are needed.
Breastfeeding infants for a period of two years is endorsed by international health agencies such as the World Health Organisation. However, discourses of breastfeeding in a British context are complex and contradictory, juxtaposing representations of breastfeeding as healthy and a moral obligation for mothers with views of the act as unseemly and an expectation that nursing women practice 'socially sensitive lactation' especially in public spaces. Sustained breastfeeding rates in the UK are poor and most British women discontinue breastfeeding well before six months. Mothers who elect to feed their infants at the breast for longer than these normative periods appear to experience suspicion and disapproval, especially in a public context and breastfeeding women are only legally protected in feeding their infants in public for up to six months. Although breastfeeding research is flourishing, research on this particular population of mothers remains relatively limited. Therefore, in this study, we explore in-depth experiential accounts of eight women, resident in a town in the East of England, who breastfed their infants beyond six months. Using interpretative phenomenological analysis four themes are presented. Really horrible looks': stigma from families and the community', 'Feeling quite exposed': managing extended breastfeeding etiquette', 'Weird freaky paedophiles': representations of extended breastfeeding women in the media' and 'You really need that': the importance of support for longer-term breastfeeding women'. Applications to extended breastfeeding promotion and advocacy are discussed.
The present study was conducted to assess the effects of effluent from a wastewater treatment plant (WWTP) on goldfish in early life stage. Fertilized eggs of the goldfish were exposed to a serial of graded concentrations of the effluent for 30 d. The hatching and survival rates of goldfish were decreased and the freaky rate was elevated with increased effluent concentrations. Additionally, the growth of fry was inhibited, and both body length and body weight were significantly decreased at > or =20% of effluent (p < 0.05). vitellogenin (Vtg) in fry was induced by all exposure concentrations. However, concentration dependence was not apparent. The highest Vtg induction was observed at the exposure of 20% effluent, whereas the induction effects of Vtg were decreased at > 20% of effluent. After a period of culture in clean water, both body length and body weight of fish were significantly increased, and Vtg levels were significantly decreased (p < 0.05). The result demonstrates that the exposure of WWTP effluents in early life stage can cause a risk of fish feminization. Goldfish seem to be suitable in assessing environmental impact of endocrine-disrupting chemicals due to their sensitivity in early life stage.
I review here some of the open questions regarding the geometry and emission mechanisms of galactic black hole candidates. For hard states, I concentrate on the perspective of ``disk+Compton coronae'' models (for discussions of jet models, see the papers by Sera Markoff). Specifically, I discuss the implications from our 10 year long RXTE monitoring campaign of Cyg X-1. I then present simultaneous RXTE/Chandra observations of the ``soft state'' black hole candidate 4U 1957+11, and discuss to what extent it does or does not allow one to test ``relativistic disk models''. The use of such models has been claimed to measure black hole spin parameters. I then briefly present a particularly freaky-weird observation of GX 339-4, where the source ``fell off'' the usual radio/X-ray correlation in the low/hard state. Questions addressed by the above observations include: are the Compton corona models unique fits to the data? (No. Jets work equally well, and simple broken power laws work better still. We argue that the latter models indicate multiple, broad-band continuum components.) Is there good evidence for a receding disk as sources transit into the hard state? (The jury is still out.) W
