The observation of Extensive Air Showers from an Earth-Orbiting Satellite
In this paper we review the main issues that are relevant for the detection
of Extensive Air Showers (EAS) from space. EAS are produced by the interaction
of Ultra-High Energy Cosmic Particles (UHECP) with the atmosphere and can be
observed from an orbiting telescope by detecting air fluorescence UV light. We
define the requirements and provide the main formulas and plots needed to
design and optimize a suitable telescope. We finally estimate its expected
performances in ideal conditions.Comment: 24 pages, 10 figures; submitted to Astroparticle Physics 27 pages, 14

Autonomous dexterous end-effectors for space robotics
The development of a knowledge-based controller is summarized for the Belgrade/USC robot hand, a five-fingered end effector, designed for maximum autonomy. The biological principles of the hand and its architecture are presented. The conceptual and software aspects of the grasp selection system are discussed, including both the effects of the geometry of the target object and the task to be performed. Some current research issues are presented
Travesty of Trust: A Critical Look at Racial and Ethnic Discrimination in the Healthcare Setting
The purpose of this thesis is to review the overarching purpose of healthcare, examine race-related disparities in minority patient outcomes within specific fields of medical practice, and discuss whether these disparities are the result of racial discrimination within the clinical setting, or are due at least partially to genetic and environmental factors, followed by an examination of how cross-cultural education for healthcare professionals can be improved to equip medical personnel with the attitudes, knowledge, and skills necessary to provide effective care to a culturally diverse patient populace. The benefits of recruiting a culturally and linguistically diverse team of healthcare providers are also discussed. Review of literature seems to indicate that poor patient outcomes for minority groups are due at least in part to forms of discrimination in healthcare provision, and therefore academic initiatives to implement for current and future medical practitioners in order to address current racial disparities and discrimination in healthcare and improve health outcomes for minority patients are also examined
Design thinking in entrepreneurship education : understanding framing and placements of problems
Abstract: Orientation: Design thinking presented an alternative lens for entrepreneurship education. Research purpose: The purpose of this article was to illustrate (with a framework) the benefits of encouraging a design-based mindset when exploring problem placement and framing to create new opportunities for entrepreneurship students. Motivation for the study: The role of placement and framing of open-complex problems has not been fully embraced in the literature on design thinking for entrepreneurship education. The seminal work of Richard Buchannan (a great influencer in the realm of design thinking) offered a deeper insight into the placement and framing of problems that could assist educators to facilitate thinking skills relevant to deal with the unpredictable contexts that future entrepreneurs have to be prepared for..

This Article will focus on those innovative sections of the Coastal Zone Management Act which provide for this expanded exercise of state-based review and regulation
Sexual distress and quality of life among women with bipolar disorder
Abstract Background Information on the association between bipolar disorder (BD), sexual satisfaction, sexual function, sexual distress and quality of life (QoL) is sparse. This study aims, in women with BD, to (i) investigate sexual dysfunction, sexual distress, general sexual satisfaction and QoL; (ii) explore whether sexual distress was related to affective symptoms and (iii) investigate whether QoL was associated with sexual distress. The study is a questionnaire survey in an outpatient cohort of women with BD using: Changes in Sexual Functioning Questionnaire, Female Sexual Distress Scale, Altman Self-Rating Mania Scale (ASRM), Major Depression Inventory (MDI) and The World Health Organisation Quality of Life-Brief. Results In total, 61 women (age range 19–63, mean 33.7 years) were recruited. Overall, 54% reported sexual distress (n = 33) and 39% were not satisfied with their sexual life (n = 24). Women with BD were significantly more sexually distressed in comparison with Danish women from the background population but they did not have a higher prevalence of impaired sexual function. Better sexual function was positively associated with ASRM scores while MDI scores were associated with more distress. Finally, the group of non-sexually distressed women with BD reported higher QoL scores compared with the sexually distressed group. Conclusions Women with BD exhibited a high prevalence of sexual distress and their sexual function seemed associated with their actual mood symptoms and perception of QoL
