The precision of photometric and spectroscopic observations has been systematically improved in the last decade, mostly thanks to space-borne photometric missions and ground-based spectrographs dedicated to finding exoplanets. The field of eclipsing binary stars strongly benefited from this development. Eclipsing binaries serve as critical tools for determining fundamental stellar properties (masses, radii, temperatures, and luminosities), yet the models are not capable of reproducing observed data well, either because of the missing physics or because of insufficient precision. This led to a predicament where radiative and dynamical effects, insofar buried in noise, started showing up routinely in the data, but were not accounted for in the models. PHOEBE (PHysics Of Eclipsing BinariEs; http://phoebe-project.org) is an open source modeling code for computing theoretical light and radial velocity curves that addresses both problems by incorporating missing physics and by increasing the computational fidelity. In particular, we discuss triangulation as a superior surface discretization algorithm, meshing of rotating single stars, light travel time effects, advanced phase computation, volume conservation in eccentric orbits, and improved computation of local intensity across the stellar surfaces that includes the photon-weighted mode, the enhanced limb darkening treatment, the better reflection treatment, and Doppler boosting. Here we present the concepts on which PHOEBE is built and proofs of concept that demonstrate the increased model fidelity. © 2016. The American Astronomical Society. All rights reserved..

Clergy and religious leaders are facing a wide variety of sexual needs and concerns within their faith communities. Conflicts over sexual issues are growing across the entire spectrum of religious denominations, and clerics remain ill prepared to deal with them. As religious communities work to remain influential in public policy debates, clergy and the institutions that train them need to be properly prepared for twenty-first century challenges that impact sexuality and religion. Clergy are often the first point of contact for sexual problems and concerns of their faith community members-complex issues centered on morals, spirituality, and ethics. Yet, there still exists a significant lack of sexual curricula in the programs that are educating our future religious leaders. The resulting paucity of knowledge leaves these leaders unprepared to address the needs and concerns of their congregants. However, with accurate, relevant human sexuality curricula integrated into theological formation programs, future leaders will be equipped to competently serve their constituencies. This paper provides a rationale for the need for such training, an overview of the faith- and theology-based history of a pilot training project, and a description of how the Christian faith and the social sciences intersect in a training pilot project's impetus and process. © 2012 Springer Science+Business Media New York.

Research in Autism Spectrum Disorders | Year: 2016
Background Social-communication deficits of adolescents with Autism Spectrum Disorder (ASD) can significantly interfere with their participation in high school activities, where conversation is the primary mode of social interaction. The purpose of this study was to extend the social-communication research in high school settings by the evaluating use of a peer-mediated intervention (PMI) during lunch on the conversational skills of three adolescents with ASD who were observed to be passive or reluctant conversationalists. Method A multiple-baseline design across participants was used to assess the effects of teaching typical peers strategies for facilitating conversation with the focal students. Peers served as the primary interventionists, but as in other PMI research, we also incorporated the use of written text cues and direct instruction for the focal students, with the aim of using text cues flexibly for a more natural conversation. Results Results indicated improvements in focal students' conversational skills including an increased number of conversational acts, initiations, and follow-up questions, and longer conversational episodes with peers. Overall assertive acts (i.e., responses not contingent upon peer requests) also increased, suggesting that the once passive conversationalists were becoming more assertive. Social validity outcome measures attested to the acceptability of the PMI and the quality of conversation between focal students and peers. Conclusions The results of this study provide preliminary evidence that PMI can produce substantial and socially-validated conversational outcomes for high school students with ASD. © 2016 Elsevier Ltd.

Physical fitness expressed through exercise can be, if done with the right intention, a form of spiritual discipline that reflects the relational love of humanity to God as well as an expression of a healthy love of the embodied self. Through an analysis of the physiological benefits of exercise science applied to the human body, this paper will demonstrate how such attention to the optimal physical fitness of the body, including weight and cardiovascular training and nutrition, is an affirmation of three foundational theological principles of human embodiment: as created in the "imago Dei", as unified body/spirit, and as part of God's creation calling for proper stewardship. In a contemporary climate where women's bodies in particular are viewed through the lens of commodification-as visual objects for sale based on prescribed notions of superficial esthetics and beauty-as well as the consistently high rates of eating disorders such as anorexia, bulimia, and obesity, authors Greenwood and Delgado offer a vision of how women and men can imagine a subjective relationship with their own bodies that reflects the abundant love of God for God's creation. Spoken from the lived experience of professional fitness competitor and trainer, as well as trained biokineticist, Dr. Greenwood presents the most current scientific data in the field of biokinetics that grounds the theological analysis offered by Dr. Delgado, whose personal journey through anorexia and scholarly emphasis on Christian theological anthropology inform this work. Taken together, Greenwood and Delgado suggest a response to God's love for humanity, including our physical bodily humanity, which entails a responsibility to attend to the physical fitness of our bodies in order to live into the fullness, flourishing and love of God's creation as God intended. © 2011 Springer Science+Business Media, LLC.

We use bulk sediment δ15N values and opal and carbon mass accumulation rates (MAR) to reconstruct nutrient utilization and export productivity at Ocean Drilling Program Site 745 (Antarctic Zone of the Southern Ocean) spanning the late Miocene through early Pleistocene (~6.5-1.4Ma). We investigate whether early Pliocene climatic warmth and subsequent cooling can be related to changes in high latitude productivity. Results indicate that δ15N values increase to above late Holocene levels from the late Miocene through the late Pliocene (6.5 to 2Ma). Opal and carbon MARs are low during the early Pliocene. Relatively high δ15N together with low export production is consistent with a more southerly position of the Polar Frontal Zone (PFZ) allowing the expansion of nitrate depleted, low nutrient upper waters south toward Site 745. The interpretation is supported by a relatively small δ15N gradient between Site 745 and a site in the Subantarctic Zone of the Southern Ocean (Site 1090). There are no unique changes in the Site 745 δ15N values or export productivity at 2.7Ma. During the late Pliocene to early Pleistocene climate transition (between ~2.1 and at 1.7Ma), δ15N values display large variations approaching those observed during the last glacial to interglacial transition in this latitude band. Opal and carbon MARs also show large fluctuations, but in the opposite sense with maxima corresponding to minima in the δ15N record and vice versa. The pattern of high δ15N values associated with low export production may reflect changes in nutrient utilization in response to changes in water column stratification once the PFZ has moved north of the location of Site 745. Our results provide a mechanism for enhancing early Pliocene CO2 concentrations via reduced uptake of CO2 due to low productivity in the Southern Ocean. Once the PFZ has moved north, the region may have become sensitive to changes in water column stratification, potentially contributing to fluctuations in CO2. © 2012 Elsevier B.V.

The wettabilities of the partially fluorinated polymers (ethylene-tetrafluoroethylene copolymer (ETFE), ethylenechlorotrifluoroethylene copolymer (ECTFE), and poly(vinylidene fluoride) (PVDF)) were investigated by contact angle measurements. Zisman plots for ETFE and ECTFE exhibited linear relationships, while the Zisman plot for PVDF showed a slight curvature, which was interpreted to indicate strong non-dispersive interactions between the surface and the contacting liquids. The Lifshitz-van der Waals forces of the fluoropolymers were estimated to increase in the order of ETFE < PVDF « ECTFE. An evaluation of the polar or "acid-base" interaction energies showed that PVDF, which possesses the most acidic hydrogens among the examined fluoropolymers, has the strongest acid-base interactions.

Bloodletting has been used extensively throughout history and across cultures. When viewed as a panacea, it is dangerous. When used strategically, it can be life saving. Likewise, mammography has come to be viewed as essential for detection of breast cancer. Research and holistic understanding of prevention and detection of disease challenges this viewpoint. Safer options for breast cancer screening are available.

Christian Bioethics | Year: 2011
The roots of much of Western medicine lie in the Christian monastic tradition and its commitment to nonstigmatizing compassionate care throughout the life cycle and to the ideal of empathic personal connection between physicians, patients, and the communities and relationships in which both of these are embedded. In the modern West, these Christianly informed aspects of medicine are increasingly being undercut as medical care becomes ever more specialized, technologized, and depersonalized. At the same time, there exist a variety of efforts to counter these tendencies and to foster a practice of medicine that is more sensitive to the personal, relational, familial, and narrative dimensions of health, illness, and medical care. There are, in particular, considerable numbers of physicians, psychologists, and psychotherapists working at the intersections of biomedical and psychosocial care, of care for individuals and care for families, and of the body and the mind. Given the natural affinity that Christian bioethicists might be expected to have to communitarian, narrative, and family-oriented approaches to health care, it is thus remarkable that there appears to be no work of Christian bioethics that interacts in any discernible way with this psychotherapeutic literature concerning health, illness, families, and the mind-body interface. Instead, Christian bioethicists appear to endorse a narrowly reductionistic biomedical view of health and illness while either ignoring the psychosocial, integrative, and collaborative literature, or actively blaming and shaming those pastors or lay Christians who might have anything to do with psychotherapy or psychosocial care. This is unbecoming and unhelpful. In the fragmented, complex, and potentially dehumanizing world that is modern medical care, those who would think Christianly about the care of the sick cannot afford to despise psychology and psychosocial care. On the contrary, the church needs psychotherapy. In this article, I will thus consider, first, what the state of the conversation is where Christian bioethics and psychosocial and psychotherapeutic care are concerned. I will then turn to some of the principal landmarks in the professional literature concerning psychotherapeutic work with the sick, the disabled, the dying, and the bereaved, particularly as these are considered in contexts that include families and lay and professional caregivers. I will then identify a few opportunities for practical and theological reflection that present themselves in this literature, and will conclude with a few comments on the substance and relationship of salvation and health. © The Author 2012.

The use of polyanion and polycation-sensitive membrane electrodes to detect five different preparations of fucoidan is described. Unlike linear polyanionic molecules previously measured with polymer membrane-based electrochemical sensors, fucoidans from marine brown algae are all highly branched, sulfated polysaccharides with varying charge densities and structures, depending on the species of seaweed, method of extraction used and extent of purification. When tridodecylmethylammonium (TDMA) was used as the ion-exchanger, a large, non-equilibrium EMF response was observed over a concentration range of 0.5-50 g mL(-1) fucoidan. Fucoidan was also measured by titration with polycationic protamine, using a dinonylnaphthalene sulfonate (DNNS)-doped membrane electrode as the potentiometric endpoint detector. Potentiometric titration was used to determine the binding ratio between protamine and fucoidan at the neutralization endpoint for each fucoidan preparation. This binding ratio was then used to successfully determine the fucoidan content of commercially available nutritional supplements. Fucoidan was also measured in undiluted blood serum, demonstrating that this method may be applicable for measuring fucoidan for clinical applications.
