Sample records for machu picchu rediscovered

  1. Machu Picchu

    Science.gov (United States)

    McKim Malville, J.

    Machu Picchu contains the highest concentration of huacas of any of the royal estates and, in addition serving as a part-time residence of the Inca, may have one of several state-supported pilgrimage centers. The large rock surrounded by the walls of the Torreon and illuminated by the light of June solstice sunrise appears to have been one of its greatest huacas. Other huacas that have astronomical associations are the Temple of the Condor, Temple of the Mortars, and the cave of Intimachay. The precision with which the Torreon and the Intimachay mark solstice sunrise sets them apart from the other astronomical sites of the Inca and may indicate a later interest in ritual calendrics at Machu Picchu.

    In early 1916, the legendary Yale University archaeologist Hiram Bingham III completed his third and final expedition in southern Peru. He shipped home 74 boxes of artifacts from Machu Picchu, a spectacular site in the Andes that is believed to have been the last major settlement of the Inca empire. Those boxes were supposed to be on temporary…

  3. At the other end of the sun's path. A new interpretation of Machu Picchu

    2009-01-01

    The Inca citadel of Machu Picchu is usually interpreted as a "royal estate" of the Inca ruler Pachacuti. This idea is challenged here by a critical reappraisal of existing sources and a re-analysis of existing evidences. It is shown that such evidences actually point at a quite different interpretation. This interpretation is suggested, on one side, by several clues coming from the urban layout, the interior arrangement of the town, the ancient access ways, the position with respect to the landscape and the cycles of the celestial bodies in Inca times and, on the other side, by a comparison with known information about the Inca pilgrimage center on the Island of the Sun of the Titicaca lake. Altogether, the abovementioned clues lead to propose that Machu Picchu was intentionally planned and built as a pilgrimage center connected with the Inca "cosmovision".

    Full Text Available The town of Machu Picchu, Peru, serves the >700 000 tourists visiting Machu Picchu annually. It has grown threefold in population in the past two decades. Due to the limited low-lying ground, construction is occurring on the unstable valley slopes. Slopes range from <10° on the valley floor to >70° in the surrounding mountains. The town has grown on a delta formed at the confluence of the Alcamayo, Aguas Calientes and Vilcanota Rivers. Geohazards in and around the town of particular concern are 1 large rocks falling onto the town and/or the rail line, 2 flash flooding by any one of its three rivers, and 3 mudflows and landslides. A prototype early warning system that could monitor weather, river flow and slope stability was installed along the Aguas Calientes River in 2009. This has a distributed modular construction allowing components to be installed, maintained, salvaged, and repaired by local technicians. A diverse set of candidate power, communication and sensor technologies was evaluated. Most of the technologies had never been deployed in similar terrain, altitude or weather. The successful deployment of the prototype proved that it is technically feasible to develop early warning capacity in the town.

    Full Text Available MACHU PICCHU: PROBLÈMES DE CONSERVATION D’UN SITE INCA DU PIEDMONT AMAZONIEN. Cet article présente la synthèse des diverses études (géomorphologie, géologie et conservation de l’architecture du site inca de Machu Picchu. Ces études ont mis en évidence les principaux facteurs de détérioration qui sont dus aux divers effets de l’eau sur l’architecture et sur le milieu environnant. La croissance de la végétation naturelle représente aussi un important facteur de détérioration qui vient s’ajouter aux effets néfastes des pluies très abondantes. Diverses mesures de protection peuvent aider à contrôler ces détériorations. D’autres facteurs, comme l’arrivée assez récente d’une végétation non autochtone et l’affluence d’un trop grand nombre de visiteurs, constituent des menaces supplémentaires. La protection du principal site archéologique et touristique du Pérou est toutefois possible en prenant des mesures adéquates contre ces agressions pour réduire autant que possible les détérioratons observées. Se presenta una síntesis de los diversos estudios (geomorfología, geología y conservación de la arquitectura realizados en el sitio inca de Machu Picchu. Estos estudios han puesto en evidencia los principales factores de deterioro que se deben a los diversos efectos del agua sobre la arquitectura y sobre el entorno. También, el desarrollo importante de la vegetación natural representa otro factor de deterioro, que se suma a los efectos nefastos del agua. Varias medidas de protección podrían mejorar el control de estos deterioros. Otros factores, tales como el crecimiento de una vegetación alógena o como la llegada de visitantes demasiado numerosos, constituyen amenazas suplementarias. Sin embargo, el principal sitio arqueológico y turístico del Perú se puede conservar con medidas adecuadas que permitirían reducir los deterioros, logrando una notable mejora de la situación actual.

    Full Text Available La région comprise entre Cuzco et Machu Picchu est située sur la terminaison orientale de la 'déflexion d'Abancay'. On y observe la superposition de deux cycles tectorogéniques: le cycle hercynien et le cycle andin. Nous verrons pourquoi l'existence du Précambrien est problématique. La série du Paléozoïque inférieur est analogue à celle connue depuis le Nord de l'Argentine. Au Dévonien supérieur à lieu la tectonique éohercynienne. Les structures qui en résultent sont polyphasées et accompagnées par 2 schistosités. Le Paléozoïque supérieur, semblable à celui du reste du Pérou, repose en discordance angulaire sur les roches plissées à l'éohercynien. En concordance sur le Paléozoïque supérieur vient la série Méso-Cénozoïque, marine jusqu'au Crétacé puis continentale. Du Lias au Sénonien notre région constitue la transition entre 2 bassins subsidents, l'un marin, l'autre continental (Altiplano. Au Sénonien la mer se retire et commence le dépôt d'une épaisse série de Couches Rouges. La sédimentation continentale est interrompue à l'Eocène supérieur-Oligocène Inférieur par la phase paroxysmale de la tectonique andine. Les failles préexistantes rejouent soit en faille inverse soit en décrochement selon leur orientation par rapport à la direction de raccourcissement. Ces rejeux complexes peuvent entraîner des inhomogénéités dans la répartition de la déformation souple et provoquer de nouvelles failles en grosses perpendiculaires aux structures. L'Oligocène voit le dépôt de molasses conglomératiques discordantes sur le substratum plissé à l'Eocène sup.-Oligocène inférieur. Le Tertiaire se termine par la mise en place à l'Oligo-Miocène de batholites granodioritiques et par un magmatisme effusif au Mio-Pliocène.

    Full Text Available By 2011, it will have been a century since Hiram Bingham "discovered" Machu Picchu. It is the most significant site when it comes to establishing the Peruvian national identity; hence, repatriation has been important for the nation's image. The arguments supporting repatriation are economical and political strategies which pursue the appropriation of the site as a cultural heritage. In this paper, we will focus on state politics which identifies this matter as an act of postcolonial reparation.

    Persons with multiple sclerosis (MS) are less physically active than nondiseased persons and often report low self-efficacy levels. In the context of an awareness project to promote physical activity and participation in MS, we addressed the impact of training for and participation in a unique expedition. Medical events, relapses, and self-reported neurological worsening were followed from 6 months before and up to 4 months afterwards. Validated patient-reported outcome measures were used to assess fatigue, self-efficacy in exercising, walking abilities, and illness perception. Nine participants completed the training, expedition, and observational study. Minor events, relapses, and/or neurological worsening were reported in six participants. The three participants with mild disability and no cardiovascular risk factors or comorbidities were free of medical and neurological events. We found a significant reduction of motor fatigue at last when compared with the first assessment. The reduction tended to be more evident in participants with mild disability (Expanded Disability Status Scale (EDSS) <4 at baseline). Cognitive fatigue, self-efficacy, and self-reported walking abilities did not change significantly. Illness perceptions tended to be reduced over time in the domains of consequences, identity, and concerns. Overall, no major adverse events occurred.

    The 1960s and 1970s were decades in which China and Africa began a friendship that was built around Beijing’s political backing and developmental aid to a crop of emerging indepen- dent African nations.In the 1980s and 1990s,China shifted its focus by devoting more efforts to establishing a rapport with big powers and neighboring countries to create a sound environment for self-development.Since the turn of the cen- tury,however,the African continent has been rediscovered by China as a strategic partner in many areas.As the Chinese market has flourished,so too has the African economy,which maintained a growth momentum in recent years and has achieved a modest prosperity rarely seen in its history.

  15. 'They don't just come for Machu Picchu': locals' views of tourist-local sexual relationships in Cuzco, Peru.

    Science.gov (United States)

    Bauer, Irmgard

    2008-08-01

    Sexual and romantic relationships between local people and tourists have long taken place. Such encounters are not a modern phenomenon, but the potential of sexually transmitted infections (STIs), including HIV/AIDS, warrants greater research into the issue. This paper analyses local people's views of local-tourist relationships in Cuzco/Peru. Data were obtained through in-depth interviews, participant and non-participant observation and informal discussions. Attraction based on physical difference was reportedly the main trigger for such relationships. Emerging themes discussed include issues of self-esteem, strategies of approach, tourists' motives, emotional involvement and expectations from such encounters. Levels of unprotected sexual behaviour and lack of STI awareness are of sufficient concern to recommend urgent action. Suggestions for sexual health education are made with particular emphasis on targeting local people involved in the tourism and hospitality industries.

    Full Text Available Intergenerational groups are a community-based group concept designed to engage and mobilize often untapped resources of older adults in effective interaction with younger populations. These groups support an atmosphere of synergistic interaction. Members of each generation share reflections on interpersonal strengths and capacities and rediscover emotional and spiritual anchors and bonding. Illustrated here is Community Connections (CC, developed using the phase driven participatory culture-specific intervention model (PCSIM; Nastasi, Moore & Varjas, 2004 that included self selected local older adults, caregivers, and multicultural exchange students. The program was structured to offer mutual opportunities for activities built around exchanging cultural and life experiences. The goals were: 1 to reduce social isolation due to age, culture, or disability 2 for international students to practice English and learn about local cultural traditions, and 3 to build intergenerational ‘extended family’ relationships.

  18. Rediscovering community--reflections after Hurricane Sandy.

    2013-01-01

    Hoboken, New Jersey, is a town of 50,000 residents located across the Hudson River from New York City. Most of Hoboken's infrastructure was compromised during Hurricane Sandy as a result of flooding and power outages that rendered many businesses inoperable, including all of the pharmacies in town. Despite a focus on emergency preparedness since Hurricane Katrina and 9/11, there were no contingencies in place to facilitate and assess the medication needs of the community in the event of a natural disaster. This essay describes how the author rediscovered the meaning of community, and through working with colleagues in other health care disciplines and non-health care volunteers, provided care to patients in suboptimal circumstances.

  3. Rediscovering ancient glass technologies through the examination of opacifier crystals

    2008-07-01

    The aim of the study is to understand how antimonate opacifying crystals were obtained throughout history. Two archaeological glass productions opacified with calcium and lead antimonates are studied in this paper, in order to rediscover ancient opaque glass technologies: Roman mosaic tesserae (1st cent. B.C. 4th cent. A.D.) and Nevers lampworking glass (18th cent. A.D.). The fine examination of crystalline phases and of the vitreous matrix is undertaken using various and complementary techniques. Results are compared with a modern reference production, for which the technological process is well known. We demonstrate that Ca-antimonate opacifiers in Roman mosaic tesserae, as well as in Nevers lampworking glass, were obtained by in situ crystallization. Nevertheless, Roman and Nevers glass would have undergone different firing processes. We propose that the addition of previously synthesized crystals or the use of “anime” could be the process used to obtain Pb-antimonate opacified glass, for both productions studied. We demonstrate that CaO, PbO and Sb2O3 concentrations in the bulk compositions and in the matrices, and their evolution with the crystallinity ratio, offer robust criteria for the distinction of the opacification process used. Also, the different crystalline structures help to provide information on the experimental conditions.

    Questions concerning both the ontology and epistemology of the "psychiatric object" (symptoms and signs) should be at the forefront of current concerns of psychiatry as a clinical neuroscience. We argue that neglect of these issues is a crucial source of the stagnation of psychiatric research....... In honor of the centenary of Karl Jaspers' book, General Psychopathology, we offer a critique of the contemporary "operationalist" epistemology, a critique that is consistent with Jaspers' views. Symptoms and signs cannot be properly understood or identified apart from an appreciation of the nature...... in the phenomenal or experiential realm are therefore a fundamental prerequisite for classification, treatment, and research. This requires a multidisciplinary approach, incorporating (among other things) insights provided by psychology, phenomenological philosophy, and the philosophy of mind....

    2013-06-01

    As part of a larger study, we offered Everyday Life Rehabilitation (ELR) as a model for integrated occupational therapy in sheltered or supported housing facilities, to enable meaningful daily occupations for people with psychiatric disabilities. Our aim with this study was to understand how participants made sense of their occupational transformations in the context of their everyday life and life history. We carried out qualitative interviews and field observations with 16 participants with psychosis-related disorders. We used narrative analysis and disclosed stories of "rediscovering agency," referring to occupational and identity transformations. A parallel outcome study has shown positive results for participants, and by using narrative inquiry we contribute with a deeper understanding of the meaning making of their transformations and mechanisms of the intervention; i.e., hope, extended value of reaching goals, reentering the majority world, transparency of process, and attunement to the individual. The findings support the use of the ELR intervention.

    Full Text Available Non-celiac gluten sensitivity (NCGS is a newly recognised clinical entity by academic medical professionals, but it is better to consider it an old diagnosis recently rediscovered. The overall prevalence of NCGS in the general population is currently unknown largely because patients often self-diagnose and place themselves on the celiac-type gluten-free diet (GFD without medical supervision. NCGS is an umbrella term and may incorporate different subgroups of patients. Now there is no specific biomarker that can be used to identify the entity. NCGS diagnosis can be reached only by excluding celiac disease and wheat allergy. Symptoms must disappear with the withdrawal of gluten and reappear quickly when gluten is reintroduced. NCGS existence has been recently supported by two expert meetings, however mechanisms by which gluten triggers symptoms, mimicking irritable bowel syndrome and skin rashes, numbness,”foggy mind”, disturbed sleep patterns, have yet to be identified. Knowledge about NCGS natural history and outcome is still lacking. NCNG is the entity awaiting better diagnostics criteria, however a dietary approach for the management of patients with gastrointestinal symptoms and lack of well being no longer seems elusive. There is a growing segment of the population that seeks out gluten-free products because of a wider notion that gluten-free constitutes a healthier option. Major area of concern that must be addressed by medical professionals is the high cost of GFD.

    2016-06-01

    Full Text Available Alessandro Spina, né Basili Shafik Khouzam, was born in Benghazi in 1927 into a family of Maronites from Aleppo and spent most of his life between Libya and Italy, speaking several languages and writing in Italian. He may be described as the “unsung” writer of Italian colonial and post-colonial past in North Africa. Spina’s oeuvre—collected in an omnibus edition, I confini dell’ombra. In terra d’oltremare (Morcelliana—charts the history of Libya from 1911, when Italy invaded the Ottoman province, to 1966, when the country witnessed the economic boom sparked by the petrodollars. The cycle was awarded the Premio Bagutta, Italy’s highest literary accolade. In 2015, Darf Press published in English the first instalment of Spina’s opus with the title The Confines of the Shadows. In Lands Overseas. Spina always refused to be pigeonholed in some literary category and to be labeled as a colonial or postcolonial author. As a matter of fact, his works go beyond the spatial and imaginary boundaries of a given state or genre, emphasizing instead the mixing and collision of languages, cultures, identities, and forms of writing. Reading and re-discovering Spina in a transcultural mode brings to light the striking newness of his literary efforts, in which transnational lived life, creative imagination, and transcultural sensibility are inextricably interlaced.

  12. Rediscovering Beta-2 Microglobulin As a Biomarker across the Spectrum of Kidney Diseases

    Directory of Open Access Journals (Sweden)

    Christos P. Argyropoulos

    2017-06-01

    Full Text Available There is currently an unmet need for better biomarkers across the spectrum of renal diseases. In this paper, we revisit the role of beta-2 microglobulin (β2M as a biomarker in patients with chronic kidney disease and end-stage renal disease. Prior to reviewing the numerous clinical studies in the area, we describe the basic biology of β2M, focusing in particular on its role in maintaining the serum albumin levels and reclaiming the albumin in tubular fluid through the actions of the neonatal Fc receptor. Disorders of abnormal β2M function arise as a result of altered binding of β2M to its protein cofactors and the clinical manifestations are exemplified by rare human genetic conditions and mice knockouts. We highlight the utility of β2M as a predictor of renal function and clinical outcomes in recent large database studies against predictions made by recently developed whole body population kinetic models. Furthermore, we discuss recent animal data suggesting that contrary to textbook dogma urinary β2M may be a marker for glomerular rather than tubular pathology. We review the existing literature about β2M as a biomarker in patients receiving renal replacement therapy, with particular emphasis on large outcome trials. We note emerging proteomic data suggesting that β2M is a promising marker of chronic allograft nephropathy. Finally, we present data about the role of β2M as a biomarker in a number of non-renal diseases. The goal of this comprehensive review is to direct attention to the multifaceted role of β2M as a biomarker, and its exciting biology in order to propose the next steps required to bring this recently rediscovered biomarker into the twenty-first century.

    The process of drug discovery and development today encompass a myriad of paths for bringing a new therapeutic molecule that has minimal adverse effects and of optimal use to the patient. Chirality was proposed in the direction of providing a purer and safer form of drug [Ex- cetrizine and levocetrizine]. Decades have passed since the introduction of this concept and numerous chiral molecules are in existence in therapeutics, yet somehow this concept has been ignored. This review aims to rediscover the ignored facts about chirality, its benefits and clear some common myths considering the example of S-Metoprolol in the management of Hypertension and other cardiovascular diseases. Relevant articles from Pubmed, Embase, Medline and Google Scholar were searched using the terms "Chiral", "Chirality", "Enantiomers", "Isomers", "Isomerism", "Stereo-chemistry", and "S-Metoprolol". Out of 103 articles found 17 articles mentioning in general about the concept of chirality and articles on study of S-metoprolol in various cardiovascular diseases were then reviewed. Many articles mention about the importance of chirality yet the concept has not been highlighted much. Clear benefits with chiral molecules have been documented for various drug molecules few amongst them being anaesthetics, antihypertensives, antidepressants. Benefits of S-metoprolol over racemate are also clear in terms of responder rates, dose of administration and adverse effects profile in various cardiovascular diseases. Chirality is a good way forward in providing a new drug molecule which is safe with lesser pharmacokinetic and pharmacodynamics variability, lesser side effects and more potent action. S-metoprolol is chirally pure form of racemate metoprolol and has lesser side effects, is safer in patients of COPD and Diabetes who also have hypertension and comparable responder rates at half the doses when compared to racemate.

    The royal estates lying between Cusco and Machu Picchu illustrate the remarkable variety by which the sun was honored and worshipped in the Inca Empire. The terraced basins of Moray combine the sun at both solstices and, perhaps, the zenith sun, with flowing water and offerings to Pachamama. The complex astronomy at Urubamba involves the palace of Quespiwanka, horizon pillars, solstices, and mountain worship. Ollantaytambo contains horizontal shadow-casting gnomons with a major water shrine.

  17. Caregiving for a loved one with dementia at the end of life: an emergent theory of rediscovering.

    2015-08-01

    Millions face the challenges of caregiving for a loved one with dementia. A classic Glaserian grounded theory methodology was used to discover the problem that caregivers of individuals with dementia face at the end of life and how they attempt to resolve that problem. Data were collected from a theoretical sample of 101 participants through in-person interviews, online interviews, book and blog memoirs of caregivers, and participant observation. Constant comparative method revealed a basic social psychological problem of role entrapment. Caregivers attempt to resolve this problem through a 5-stage basic social psychological process of rediscovering including missing the past, sacrificing self, yearning for escape, reclaiming identity, and finding joy. Health care professionals can support caregivers through this journey by validating, preparing caregivers for future stages, and encouraging natural coping strategies identified in this process. This study provides a substantive theory that may serve as a framework for future studies. © The Author(s) 2014.

    Accurate distribution data are critical to the development of conservation and management strategies for imperiled species, particularly for narrow endemics with life history traits that make them vulnerable to extinction. Medionidus walkeri is a rare freshwater mussel endemic to the Suwannee River Basin in southeastern North America. This species was rediscovered in 2012 after a 16-year hiatus between collections and is currently proposed for listing under the Endangered Species Act. Our study fills knowledge gaps regarding changes in distribution and early life history requirements of M. walkeri. Spatiotemporal changes in M. walkeri distribution were displayed using a conservation status assessment map incorporating metadata from 98 historical (1916–1999) and 401 recent (2000–2015) site surveys from museums and field notes representing records for 312 specimens. Recent surveys detected M. walkeri only in the middle Suwannee subbasin (n = 86, 22 locations) and lower Santa Fe subbasin (n = 2, 2 locations), and it appears the species may be extirpated from 67% of historically occupied 10-digit HUCs. In our laboratory experiments, M. walkeri successfully metamorphosed onPercina nigrofasciata (56.2% ± 8.9) and Etheostoma edwini (16.1% ± 7.9) but not on Trinectes maculatus, Lepomis marginatus, Notropis texanus, Noturus leptacanthus, Etheostoma fusiforme, orGambusia holbrooki. We characterize M. walkeri as a lure-displaying host fish specialist and a long-term brooder (bradytictic), gravid from fall to early summer of the following year. The early life history and distribution data presented here provide the baseline framework for listing decisions and future efforts to conserve and recover the species.

    The Central Texas endemic freshwater mussel, Quadrula mitchelli (Simpson in Dall, 1896), had been presumed extinct until relict populations were recently rediscovered. To help guide ongoing and future conservation efforts focused on Q. mitchelli we set out to resolve several uncertainties regarding its evolutionary history, specifically its unknown generic position and untested species boundaries. We designed a molecular matrix consisting of two loci (cytochrome c oxidase subunit I and internal transcribed spacer I) and 57 terminal taxa to test the generic position of Q. mitchelli using Bayesian inference and maximum likelihood phylogenetic reconstruction. We also employed two Bayesian species validation methods to test five a priori species models (i.e. hypotheses of species delimitation). Our study is the first to test the generic position of Q.mitchelli and we found robust support for its inclusion in the genusFusconaia. Accordingly, we introduce the binomial, Fusconaia mitchelli comb. nov., to accurately represent the systematic position of the species. We resolved F. mitchelli individuals in two well supported and divergent clades that were generally distinguished as distinct species using Bayesian species validation methods, although alternative hypotheses of species delineation were also supported. Despite strong evidence of genetic isolation within F. mitchelli, we do not advocate for species-level status of the two clades as they are allopatrically distributed and no morphological, behavioral, or ecological characters are known to distinguish them. These results are discussed in the context of the systematics, distribution, and conservation ofF. mitchelli.

  20. Rediscovering market segmentation.

    2006-02-01

    In 1964, Daniel Yankelovich introduced in the pages of HBR the concept of nondemographic segmentation, by which he meant the classification of consumers according to criteria other than age, residence, income, and such. The predictive power of marketing studies based on demographics was no longer strong enough to serve as a basis for marketing strategy, he argued. Buying patterns had become far better guides to consumers' future purchases. In addition, properly constructed nondemographic segmentations could help companies determine which products to develop, which distribution channels to sell them in, how much to charge for them, and how to advertise them. But more than 40 years later, nondemographic segmentation has become just as unenlightening as demographic segmentation had been. Today, the technique is used almost exclusively to fulfill the needs of advertising, which it serves mainly by populating commercials with characters that viewers can identify with. It is true that psychographic types like "High-Tech Harry" and "Joe Six-Pack" may capture some truth about real people's lifestyles, attitudes, self-image, and aspirations. But they are no better than demographics at predicting purchase behavior. Thus they give corporate decision makers very little idea of how to keep customers or capture new ones. Now, Daniel Yankelovich returns to these pages, with consultant David Meer, to argue the case for a broad view of nondemographic segmentation. They describe the elements of a smart segmentation strategy, explaining how segmentations meant to strengthen brand identity differ from those capable of telling a company which markets it should enter and what goods to make. And they introduce their "gravity of decision spectrum", a tool that focuses on the form of consumer behavior that should be of the greatest interest to marketers--the importance that consumers place on a product or product category.

    trayectorias de sujetos sexuales. El trabajo de los psicólogos se verá beneficiado en su formación al redescubrir la sexualidad, superar los abordajes psicológicos con pretensiones universalistas, por lo menos en el dominio sexual.Common sense designates the psychologist the most proficient professional to work with sexuality. Rarely, though, we are educating psychologists to work with the sexual life in non-clinical contexts. This article synthesizes a critique of the "sexological" framework, hegemonic throughout the XX century, and argues that the "constructionist" approach, while deconstructing woman's subordination and hetero-normativeness as natural, was validated as an alternative paradigm of great relevance for research and professional practice approaching the sexual sphere. This theoretical framework better understood challenges as the Aids epidemic, especially in contexts of inequality and rights violations; inspired technologies for its prevention based on gender analysis and the understanding of sexual scenarios, scenes, scripts and trajectories by sexual subjects. Psychologists practice will benefit from rediscovering sexuality, surpassing approaches based on personal values, rethinking the sexological and psychological approaches that aim at universalism, at least on the sexuality domain.

  8. Rediscovering Antiquity: Karl Weber and the Excavation of Herculaneum, Pompeii, and Stabiae, by C.C. Parslow. Cambridge University Press, 1995

    James E. Snead

    1997-11-01

    Full Text Available Rediscovering Antiquity is an example of the genre of historical writing which seeks to recast the careers of little-known figures who have fallen into obscurity. This is typically intended to move them and their work into the proper "lineage," that is, the select group of ancestral figures from which modern practices are derived. Parslow is interested in the 18th century excavations of the Vesuvian cities, which, he argues, have been misunderstood by historians of archaeology. Indeed, common sources, such as Daniel (1981:55, describe the initial explorations of Pompeii, Herculaneum, and Stabiae, sponsored by the Bourbon kings of Naples as "...treasure hunts and not serious excavations." While the Roman artifacts removed from the sites are credited with spurring interest in antiquity in Enlightenment Europe, modern scholars have until now devoted little attention to the means through which they were recovered.

  10. A Well-Kept Treasure at Depth: Precious Red Coral Rediscovered in Atlantic Deep Coral Gardens (SW Portugal after 300 Years.

    Directory of Open Access Journals (Sweden)

    Joana Boavida

    Full Text Available The highly valuable red coral Corallium rubrum is listed in several Mediterranean Conventions for species protection and management since the 1980s. Yet, the lack of data about its Atlantic distribution has hindered its protection there. This culminated in the recent discovery of poaching activities harvesting tens of kg of coral per day from deep rocky reefs off SW Portugal. Red coral was irregularly exploited in Portugal between the 1200s and 1700s, until the fishery collapsed. Its occurrence has not been reported for the last 300 years.Here we provide the first description of an Atlantic red coral assemblage, recently rediscovered dwelling at 60-100 m depth in southern Portugal. We report a very slow growth rate (0.23 mm year-1, comparable to Mediterranean specimens. In comparison with most of the Mediterranean reports, the population reaches much larger sizes, estimated to be over one century old, and has a more complex coral branch architecture that promotes a rich assemblage of associated species, with boreal and Mediterranean affinities. Atlantic red coral is genetically distinct, yet mitochondrial analyses suggest that red corals from the Atlantic may have introgressed the Mediterranean ones after migration via the Algeria current. Our underwater surveys, using advanced mixed-gas diving, retrieved lost fishing gear in all coral sites. Besides illegal harvesting, the use and loss of fishing gears, particularly nets, by local fisheries are likely sources of direct impacts on these benthic assemblages.We extended the knowledge on the distribution of C. rubrum in the Atlantic, discovered its genetic distinctiveness, and reveal a rich deep-dwelling fauna associated to these coral assemblages. These findings support a barrier role of the Atlantic-Mediterranean transition zone, but reveal also hints of connectivity along its southern margin. The results highlight the genetic and demographic uniqueness of red coral populations from SW Iberia

  13. The Vallipuram Buddha Image "Rediscovered"

    1996-01-01

    Full Text Available When, at the end of the 19th century, the Visnu kovil in Vallipuram, in Vatamaracci, in northern Ilam (Lanka was (rebuilt, a Buddha statue was unearthed close to this temple, 50 yardsnortheast of it. It remained in the lumber room of this temple until 1902, when it was set up in Old Park at Yalppanam under a bo-tree. In 1906, the Vallipuram Buddha image was presented by Governor Sir Henry Blake to the King of Siam, who was particularly anxious to have it, as it was supposed to be of an archaic type. This event together with the statue, was forgotten for almost 90 years. All Tamilar and Sinhalese born after 1906 have never seen the Vallipuram Buddha image, provided they have not gone to and found it in Thailand. The study of the religious significance per se, in its historical setting, of the statue is important. The Vallipuram Buddha image is a typical creation of Amaravati art, the spread of which documents the spread of Buddhism to Ilam, where it exercised a decisive influence on the first period of the development of Buddhist art in the Anuratapuram school. We get then a geographical triangle of a cultural encounter between Amaravati, Anuratapuram in its first phase, and Vallipuram. This happened at a time when Buddhism was still not identified as Sinhala Buddhism, but just as Buddhism. The study of the Vallipuram statue is thus a way of transcending or at least suspending for some time polarising ethnic identities, not ethnic identities as such.

    2010-05-01

    The present work is finalised at the implementation of a landslide risk mitigation master plan of the ancient citadel of Machu Picchu. After the warning launched in March 2001, by the scientific community on potential collapse of the citadel from a near-disastrous landslide event different studies have been promoted to reconstruct landslide activity and suggest landslide risk mitigation measures for the protection and conservation of Machu Picchu cultural heritage. A site-scale analysis has been implemented following the application and integration of geomechanical classifications, ambient noise measurements and structural and kinematical analysis. The geology of the area is characterized by granitoid bodies that had been emplaced in the axial zones of the main rift system that are now exposed at the highest altitudes, together with country rocks (Precambrian and Lower Paleozoic metamorphics) originally constituting the rift ‘roots'. The bedrock of the Inca citadel of Machu Picchu is mainly composed by granite and subordinately granodiorite. This is mainly located in the lower part of the slopes. Superficially, the granite is jointed in blocks with variable dimensions, promoted by local structural setting. Single blocks vary from 10-1 to about 200 m3. Soil cover, widely outcropping in the area, is mainly composed by individual blocks and subordinately by coarse materials originated by chemical and physical weathering of minerals. Regional tectonic uplift and structural setting rule the general morphological features of the area and as a consequence, landslide type and evolution. Rock falls, rock slides, debris flows and debris slides are the main landslide typologies affecting the citadel slopes. In the last mission in May 2009, elastic and deformation rock parameters have been collected using a passive seismic innovative technique based on natural microtremor measurements and geostructural scan lines elaboration. A landslide zoning of the citadel has been

  3. Europe rediscovers the Moon with SMART-1

    Science.gov (United States)

    2006-08-01

    The whole story began in September 2003, when an Ariane 5 launcher blasted off from Kourou, French Guiana, to deliver the European Space Agency’s lunar spacecraft SMART-1 into Earth orbit. SMART-1 is a small unmanned satellite weighing 366 kilograms and roughly fitting into a cube just 1 metre across, excluding its 14-metre solar panels (which were folded during launch). After launch and injection into an elliptical orbit around the Earth, the gentle but steady push provided by the spacecraft’s highly innovative electric propulsion engine forcefully expelling xenon gas ions caused SMART-1 to spiral around the Earth, increasing its distance from our planet until, after a long journey of about 14 months, it was “captured” by the Moon’s gravity. To cover the 385,000 km distance that separates the Earth from the Moon if one travelled in a straight line, this remarkably efficient engine brought the spacecraft on a 100 million km long spiralling journey on only 60 litres of fuel! The spacecraft was captured by the Moon in November 2004 and started its scientific mission in March 2005 in an elliptical orbit around its poles. ESA’s SMART-1 is currently the only spacecraft around the Moon, paving the way for the fleet of international lunar orbiters that will be launched from 2007 onwards. The story is now close to ending. On the night of Saturday 2 to Sunday 3 September, looking at the Moon with a powerful telescope, one may be able to see something special happening. Like most of its lunar predecessors, SMART-1 will end its journey and exploration of the Moon by landing in a relatively abrupt way. It will impact the lunar surface in an area called the “Lake of Excellence”, situated in the mid-southern region of the Moon’s visible disc at 07:41 CEST (05:41 UTC), or five hours before if it finds an unknown peak on the way. The story is close to ending After 16 months harvesting scientific results in an elliptical orbit around the Moon’s poles (at distances of between 300 and 3.000 km), the mission is almost over. The spacecraft perilune has now dropped below an altitude of 300 km from the lunar surface and will get a closer look at specific targets on the Moon before landing in a controlled manner on the moon surface (controlled, that is, in terms of where and when). It will then “die” there. “With a relative low speed at impact (2 km/sec or 7200 km/h), SMART-1 will create a small crater of 3 to 10m in diameter’s” says Bernard Foing, SMART-1 Project scientist, “a crater no larger than that created by a 1kg meteorite on a surface already heavily affected by natural impacts”. Mission controllers at the European Space Agency’s Operations Centre (ESOC) in Darmstadt, near Frankfurt, Germany will monitor the final moments before impact step by step. Final milestones of SMART-1 flight operations In June, SMART-1 mission controllers at ESOC completed a series of complex thruster firings aimed at optimising the time and location of the spacecraft’s impact on the Moon's surface. They had to be done with the thrusters of the attitude control system since all the Xenon of the Ion engine had been consumed in 2005. The manoeuvres have shifted the time and location of impact, which would otherwise occurred in mid-August on the far side of the Moon; impact is now set to occur on the near side and current best estimates show the impact time to be around 07:41 CEST (05:41 UTC) on Sunday 3 September. "Mission controllers and flight dynamics engineers have analysed the results of the manoeuvre campaign to confirm and refine this estimate," says Octavio Camino-Ramos, SMART-1 spacecraft operations manager at ESA/ESOC. "The final adjustment manoeuvres are planned for 25th of August, which may still have a consequence on the final impact time", he added. Large ground telescopes will be involved before and during impact to make observations of the event, with several objectives: - To study the physics of the impact (ejected material, mass, dynamics and energy involved). - To analyse the chemistry of the surface by co

    Full Text Available In this article, a few of the elements and dynamics of social movements will be explored. It will be argued that the traditional institutional church is in a critical period in the cycle of movements, where the need for the (rediscovery of our missional-incarnational ethos and the theology of restoration might energise the church to (reactivate the dynamics of movements. The narrative of Jesus and the Samaritan woman in John 4 will be investigated as an example of Jesus’s missionalincarnational ethos and of the relation to a theology of restoration. Finally, some challenges for the church with regard to ecclesiology, spirituality and leadership will be proposed.

    2010-11-01

    Full Text Available Community service work, volunteerism and mentoring have recently become popular topics of research as effective methods in improving self-esteem and civic responsibility. In the current study we explored the relationship between participation in a community service gardening program and ethnocentrism. We hypothesised that an inverse correlation would emerge where students who participated in a community service-gardening program would increase their perceptions of the importance of community service work and decrease their scores in ethnocentrism. Results of the paired samples t-test strongly support the hypothesis that community service gardening work significantly reduces reports of ethnocentrism: t(10 = -2.52, (p < .03 for community college students. The ramifications of the study and ramifications for future research are offered.

  7. Rediscovering the Crystal Chemistry of Borides.

    2017-03-21

    For decades, borides have been primarily studied as crystallographic oddities. With such a wide variety of structures (a quick survey of the Inorganic Crystal Structure Database counts 1253 entries for binary boron compounds!), it is surprising that the applications of borides have been quite limited despite a great deal of fundamental research. If anything, the rich crystal chemistry found in borides could well provide the right tool for almost any application. The interplay between metals and the boron results in even more varied material's properties, many of which can be tuned via chemistry. Thus, the aim of this review is to reintroduce to the scientific community the developments in boride crystal chemistry over the past 60 years. We tie structures to material properties, and furthermore, elaborate on convenient synthetic routes toward preparing borides.

    2012-01-01

    In 1949, propylhexedrine replaced amphetamine sulfate as the active ingredient in over the counter Benzedrex due to reports of widespread abuse, psychosis and sudden death. Since its introduction, cases of psychosis, myocardial infarction, pulmonary vascular disease, pulmonary hypertension, and sudden death attributed to propylhexedrine abuse have been well documented, usually in the form of single case reports. Although growing concerns during the 1980's regarding its abuse potential and its use as a precursor in the manufacture of compounds of even higher abuse potential caused propylhexedrine to be reviewed by the WHO Expert Committee on Drug Dependence, no formal studies of the dependence potential of propylhexedrine exists to date. The following is a case of propylhexedrine dependence, with some of its history, revisited.

  11. Symmetry as Bias: Rediscovering Special Relativity

    Science.gov (United States)

    Lowry, Michael R.

    1992-01-01

    This paper describes a rational reconstruction of Einstein's discovery of special relativity, validated through an implementation: the Erlanger program. Einstein's discovery of special relativity revolutionized both the content of physics and the research strategy used by theoretical physicists. This research strategy entails a mutual bootstrapping process between a hypothesis space for biases, defined through different postulated symmetries of the universe, and a hypothesis space for physical theories. The invariance principle mutually constrains these two spaces. The invariance principle enables detecting when an evolving physical theory becomes inconsistent with its bias, and also when the biases for theories describing different phenomena are inconsistent. Structural properties of the invariance principle facilitate generating a new bias when an inconsistency is detected. After a new bias is generated. this principle facilitates reformulating the old, inconsistent theory by treating the latter as a limiting approximation. The structural properties of the invariance principle can be suitably generalized to other types of biases to enable primal-dual learning.

    The validation of the sentinel node concept in oncology has led to the rediscovery of lymphoscintigraphy. By combining preoperative lymphatic mapping with intraoperative probe detection this nuclear medicine procedure is being increasingly used to identify and detect the sentinel node in melanoma, breast cancer, and in other malignancies such as penile cancer and vulvar cancer. In the past lymphoscintigraphy has been widely applied for various indications in oncology, and in the case of the internal mammary lymph-node chain its current use in breast cancer remains essential to adjust irradiation treatment to the individual findings of each patient. In another diagnostic area, lymphoscintigraphy is also useful to document altered drainage patterns after surgery and/or radiotherapy; its use in breast cancer patients with upper limb oedema after axillary lymph-node dissection or in melanoma patients with lower-extremity oedema after groin dissection can provide information for physiotherapy or reconstructive surgery. Finally, the renewed interest in lymphoscintigraphy in oncology has led not only to the rediscovery of findings from old literature reports, but also to a discussion about methodological aspects such as tracer characteristics, image acquisition or administration routes, as well as to discussion on the study of migration patterns of radiolabelled colloid particles in the context of cancer dissemination. All this makes the need for standardized guidelines for lymphoscintigraphy mandatory. (orig.) With 10 figs., 1 tab., 56 refs.

    2017-06-01

    In this paper, the retaining walls in the agricultural terraces built by the Incas are analyzed from a mechanical point of view. In order to do so, ten different walls from the Lower Agricultural Sector of Machu Picchu, Perú, were selected using images from Google Street View and Google Earth Pro. Then, these walls were digitalized and their mechanical stability was evaluated. Firstly, it was found that these retaining walls are characterized by two distinctive features: disorder and a block size distribution with a large size span, i.e., the particle size varies from blocks that can be carried by one person to large blocks weighing several tons. Secondly, it was found that, thanks to the large span of the block size distribution, the factor of safety of the Inca retaining walls is remarkably close to those that are recommended in modern geotechnical design standards. This suggests that these structures were not only functional but also highly optimized, probably as a result of a careful trial and error procedure.

    The NASA Sun-Earth Connection Education forum annually promotes and event called Sun-Earth Day: a national celebration of the Sun, the space around the Earth (geospace), and how all of it affects life on our planet. For the past 3 years this event has provided a venue by which classrooms, museums, planetaria, and at NASA centers have had a sensational time sharing stories, images, and activities related to the Sun-Earth connections and the views o fthe Sun from Earth. Each year we select a different theme by which NASA Space Science can be further related to cross-curricular activities. Sun-Earth Day 2002, "Celebrate the Equinox", drew parallels between Native American Cultures and NASA's Sun-Earth Connection research via cultural stories, interviews, web links, activities and Native American participation. Sun-Earth Day 2003, "Live From the Aurora", shared the beauty of the Aurora through a variety of activities and stories related to perspectives of Northern Peoples. Sun-Earth Day 2004 will share the excitement of the transit of Venus through comparisons of Venus with Earth and Mars, calculations of the distances to nearby stars, and the use of transits to identify extra-solar planets. Finally, Sun-Earth Day 2005 will bring several of these themes together by turning our focus to the history and culture surrounding ancient observatories such as Chaco Canyon, Machu Picchu, and Chichen Itza.

  18. Moon-Struck: Artists Rediscover Nature And Observe

    Science.gov (United States)

    Pasachoff, Jay M.; Olson, Roberta J. M.

    We discuss rare early depictions of the Moon by artists who actually observed Earth's nearest neighbor rather than relying on stylized formulas. The earliest, from the 14th and 15th centuries, reveal that revolutionary advances in both pre-telescopic astronomy and naturalistic painting could go hand-in-hand. This link suggests that when painters observed the world, their definition of world could also include the heavens and the Moon. Many of the artists we discuss - e.g., Pietro Lorenzetti, Giotto, and Jan Van Eyck - actually studied the Moon, incorporating their studies into several works. We also consider the star map on the dome over the altar in the Old Sacristy of San Lorenzo, Florence (c. 1442), whose likely advisor was Toscanelli. In addition, we examine representations by artists who painted for Popes Julius II and Leo X - Raphael and Sebastiano del Piombo, both of whom were influenced by individuals at the papal court, such as the astronomer, painter, and cartographer Johann (Giovanni) Ruysch and Leonardo da Vinci. We also discuss Leonardo's pre-telescopic notes and lunar drawings as they impacted on art and science in Florence, where Galileo would study perspective and chiaroscuro. Galileo's representations of the Moon (engraved in his Sidereus Nuncius, 1610) are noted, together with those by Harriot and Galileo's friend, the painter Cigoli. During the 17th century, the Moon's features were telescopically mapped by astronomers with repercussions in art, e.g., paintings by Donati Creti and Raimondo Manzini as well as Adam Elsheimer. Ending with a consideration of the 19th-century artists/astronomers John Russell and John Brett and early lunar photography, we demonstrate that artistic and scientific visual acuity belonged to the burgeoning empiricism of the 14th, 15th, and 16th centuries that eventually yielded modern observational astronomy.

  1. Rediscovering psychopathology: the epistemology and phenomenology of the psychiatric object.

    Science.gov (United States)

    Parnas, Josef; Sass, Louis A; Zahavi, Dan

    2013-03-01

    Questions concerning both the ontology and epistemology of the "psychiatric object" (symptoms and signs) should be at the forefront of current concerns of psychiatry as a clinical neuroscience. We argue that neglect of these issues is a crucial source of the stagnation of psychiatric research. In honor of the centenary of Karl Jaspers' book, General Psychopathology, we offer a critique of the contemporary "operationalist" epistemology, a critique that is consistent with Jaspers' views. Symptoms and signs cannot be properly understood or identified apart from an appreciation of the nature of consciousness or subjectivity, which in turn cannot be treated as a collection of thing-like, mutually independent objects, accessible to context-free, "atheoretical" definitions or unproblematic forms of measurement (as is often assumed in structured interviewing). Adequate and faithful distinctions in the phenomenal or experiential realm are therefore a fundamental prerequisite for classification, treatment, and research. This requires a multidisciplinary approach, incorporating (among other things) insights provided by psychology, phenomenological philosophy, and the philosophy of mind.

  2. Writing-up and writing-as: rediscovering nursing scholarship.

    Science.gov (United States)

    Rolfe, Gary

    2009-11-01

    Nursing is a relatively young academic discipline which only moved en masse into the higher education sector in many countries during the 1990s. Perhaps in a bid to enhance and accelerate its credibility, the nursing academy has embraced the values and practices of evidence-based medicine and the associated 'gold-standard' experimental research paradigm as its dominant discourse. Empirical scientific research has become the most valued and highly rewarded activity for nurse academics to pursue, and the tenets and standards of research have come to define the entire academic project of nursing. As a result, there has been a gradual shift from nursing as an academic discipline founded on scholarship to one based on research. Research is no longer seen as merely one aspect of the scholarly work expected of an academic, and is now often regarded as the main (and sometimes the only) activity necessary to gain promotion. I argue in this paper for a more positive view of scholarship; indeed, that scholarly activity is both the foundation and the creative driver of the academy. I suggest that the 'gold-standard' academic output of the research report is restricted in the contribution it is able to make to the development of the discipline of nursing, and that a far broader and more critical academic base is required. Whilst empirical research supplies the basic building blocks of the discipline, it is critical and creative scholarship that provides the plans and designs that turn these piles of bricks into useful structures.

    Research in the late 80's on technological companies that develop products of high value innovation, with sufficient speed and flexibility to adapt quickly to changing market conditions, gave rise to the new set of methodologies known as Agile Management Approach. In the current changing economic scenario, we considered very interesting to study the similarities of these Agile Methodologies with other practices whose effectiveness has been amply demonstrated in both the West and Japan. Strategies such as Kaizen, Lean, World Class Manufacturing, Concurrent Engineering, etc, would be analyzed to check the values they have in common with the Agile Approach.

    Some individuals make contributions so vital to their field of knowledge that their names become almost synonymous with that field. This is the case of Sig Socransky and the field of periodontal microbiology. Sig Socransky, or simply Sig, was born in Toronto, Canada and received his DDS degree from the University of Toronto in 1957. He studied microbiology and periodontology at Harvard, receiving a certificate in 1961. That same year he was recruited to work as a Research Associate at the Forsyth Dental Center. In 1968, he was nominated Senior Member of the Staff and Head of the Department of Periodontology. During his 50-year career at Forsyth, Sig published over 300 manuscripts, keeping an average of 7 publications per year. His work had an indelible impact in the fields of periodontology and oral microbiology. All these accomplishments pale in comparison with the impact that Sig had on a personal level. We have collected testimonials from some of his former students, closest collaborators, and friends in an attempt to give readers an insight into Sig's personality. We hope we can offer those who knew him through his work a glimpse of how it felt to interact with this remarkable individual.

Discipleship was defined as participating in the Triune God’s life-giving mission and as being on a journey towards flourishing life.It showed that the gospel message of joy, good news and life in fullness serves as a counterculture against the prevailing rhetoric of religious and secular prosperity gospels, consumerism and individualism. It also warned that discipleship in mission is costly and radical. Discipleship is a life of generosity and service, where the true disciple delights in justice, gives generously and cares for the weak.The research concluded with a discussion of practical holistic practices of embodied discipleship – practices that will form habits where disciples will live a flourishing life.

    Eleven randomized control trials examined whether additional support by a trained lay person (called a doula), student midwife or midwife, who provides continuous support consisting of praise, encouragement, reassurance, comfort measures, physical contact and explanations about progress during labor, will affect obstetrical and neonatal outcomes. The women were healthy primigravidas at term. Meta-analysis of these studies showed a reduction in the duration of labor, the use of medications for pain relief, operative vaginal delivery, and in many studies a reduction in caesarian deliveries. At 6 weeks after delivery in one study a greater proportion of doula-supported women were breastfeeding, reported greater self-esteem, less depression, a higher regard for their babies and their ability to care for them compared to the control mothers. Observations during labor showed that fathers remained farther away from mothers than doulas, talked and touched less. When the doula was present with the couple during labor the father offered more personal support. The father-to-be' s presence during labor and delivery is important to the mother and father, but it is the presence of the doula that results in significant benefits in outcome.

  9. [Pierre Bayen rediscovers the Essays of Jean Rey].

    2014-10-01

    Jean Rey, a physician from The Bugue, a little town near Bergerac, published, in 1630, a book entitled "Essays" in which he explained the increase of the mass of lead, when it was strongly heated, by the fixation of a part of the air. This revolutionary publication was not received by the European scientists, because the Father Mersenne, "the secretary of learned Europe", was not able to repeat his experiments. Between 1774 and 1775, Pierre Bayen, who was a military apothecary, published his Works concerning the "precipitate per se", for us HgO, showing that when this compound was destroyed by heating, it produced a gas, and that the mass of this gas and the mass of the mercury obtained were equal to the mass of the "precipitate per se". He concluded that the phlogiston theory was contradictory with the results of the experiments. When, later on, Lavoisier published his important article on the increase of the mass of steal when it was heated in the air, he "forgot" to cite the Works of Bayen. In January 1775, Pierre Bayen published a letter in which he mentioned that he had discovered an exemplar of Jean Rey's book and explained that this physician of the 17th century had supposed the explanation that had been proved by Lavoisier. Nicolas Gobet then published a new edition of the "Essays" in 1777, but this new edition became itself quite rare. An inscription pencilled on the book kept by the British Museum pretends that all the exemplars Lavoisier could find were destroyed. It is not rigorous to conclude on a single document, especially when it is not signed, but it is sufficient to induce doubt.

If read systematically, the book presents an anthological review which establishes the continuity of the genre from 1764 to the early twenty-first century. Even though it privileges theory over textual analysis, the book can be used to elucidate numerous cultural productions and developments that have influenced the simultaneous evolution and devolution of horror by offering a precise insight into the continual interaction of social and literary spheres. Horror: A Literary History is valuable precisely because it questions the devalorizing stances towards the horror genre by acknowledging the importance of various writers who have contributed to the evolution of American and British literature but have often been marginalized because of their tendencies to transgress into the horror genre.

  13. Addressing the "New" NEC: Part I: rediscovering the basics.

    Simmonds, Aryeh; LaGamma, Edmund F

    2006-11-01

    Epithelial cell functions ultimately define the ability of the extremely low birth weight human fetus to survive outside of the uterus. These specialized epithelial cell capacities manage all human interactions with the ex utero world including: (i) lung mechanics, surface chemistry and gas exchange, (ii) renal tubular balance of fluid and electrolytes, (iii) barrier functions of the intestine and skin for keeping bacteria out and water in, plus enabling intestinal digestion, as well as (iv) maintaining an intact neuroepithelium lining of the ventricles of the brain and retina. In Part I of this two part review, the authors describe why the gut barrier is a clinically relevant model system for studying the complex interplay between innate and adaptive immunity, dendritic &epithelial cell interactions, intraepithelial lymphocytes, M-cells, as well as the gut associated lymphoid tissues where colonization after birth, clinician feeding practices, use of antibiotics as well as exposure to prebiotics, probiotics and maternal vaginal flora all program the neonate for a life-time of immune competence distinguishing "self" from foreign antigens. These barrier defense capacities become destructive during disease processes like necrotizing enterocolitis (NEC) when an otherwise maturationally normal, yet dysregulated and immature, immune defense system is associated with high levels of certain inflammatory mediators like TNFa. In Part II, the authors will discuss the theoretical advantages of using rhG-CSF in managing NEC or sepsis by augmenting neonatal neutrophil number and killing capacity including an unexpected, paradoxical and potent anti-TNFa function that may serve to limit extension of tissue destruction without impairing bacterial killing capacity. The authors conclude by arguing that NEC may be the ideal disease process for testing whether a clearly defined clinical benefit of cytokine therapy can prove beneficial.

    Full Text Available Abstract This study examined the self theory of Carl Rogers in depth. There are some important concepts illuminated well, considering one's personality development. Its main focus was positive regard, self-worth and actualizing tendency, proposed by Rogers. To explain them in brief, positive regard was studied through self-image, ideal self and congruence. Self-worth is described as conditional and unconditional to cope with challenges in life, tolerate failures and sadness at times. Actualizing tendency was expounded into fully functioning or self-actualizing. These all concepts indicated that having a tendency on human behavior and concentrating on the capacity of individuals to think intentionally and soundly, to control their biological urges, are significantly main elements to evaluate one’s self. Therefore, in the humanistic perspective, individuals have the opportunity and will to change their states of mind and behavior. This study might be a guide to some certain aspect of self related studies for other researchers to benefit accordingly and also to develop a new scale related to self using Rogers’s theory.

Here we report the rediscovery of the Hula painted frog, the first amphibian to have been declared extinct. We provide evidence that not only has this species survived undetected in its type locality for almost 60 years but also that it is a surviving member of an otherwise extinct genus of alytid frogs, Latonia, known only as fossils from Oligocene to Pleistocene in Europe. The survival of this living fossil is a striking example of resilience to severe habitat degradation during the past century by an amphibian.

  18. Will Universities Rediscover Their Core Mission as They Shrink?

    If one intends to speculate about the effects of the bursting of the higher education bubble, one can gain some insight by examining universities that are already shrinking. The University of California (UC) system's state appropriation, for example, has decreased by almost a billion dollars since 2007-2008. In this article, the author talks about…

  19. Characterization of a rediscovered haplosporidian parasite from cultured Penaeus vannamei.

    Mortalities of Penaeus vannamei, cultured in ponds in Belize, Central America, began during the last part of the grow-out cycle during the cold weather months from September 2004 through February 2005. Tissue squashes of infected hepatopancreata and histological examination of infected shrimp revealed that the mortalities might have been caused by an endoparasite. To confirm the diagnosis, DNA was extracted from ethanol preserved hepatopancreata and the small-subunit rRNA gene was sequenced. The 1838 bp sequence was novel and phylogenetic analysis placed the P. vannamei parasite within the phylum Haplosporidia as a sister taxon to a clade that includes Bonamia and Minchinia species. In situ hybridization was performed using anti-sense DNA probes that were designed to hybridize specifically with the parasite's nucleic acid. This organism presents similar characteristics to those of a haplosporidian that infected cultured P. vannamei imported from Nicaragua into Cuba, as described by Dyková et al. (1988; Fish Dis 11:15-22).

This raises a broader issue: the critical need, when projects attempt to span disciplines, to fully examine work from all relevant backgrounds.

  3. Clobazam: A Safe, Efficacious, and Newly Rediscovered Therapeutic for Epilepsy.

    Science.gov (United States)

    Gauthier, Angela C; Mattson, Richard H

    2015-07-01

    Clobazam is an oral 1,5-benzodiazepine used worldwide for the treatment of many types of epilepsies, although it is currently only approved for Lennox-Gastaut syndrome in the USA. This anticonvulsant and anxiolytic therapeutic has repeatedly demonstrated great efficacy and a high safety profile in refractory epilepsy as well as in a few monotherapy trials in both children and adults. Clobazam allosterically activates the GABAA receptor, and it binds less to subunits that mediate sedative effects than other benzodiazepines. It acts quickly, maintaining a therapeutic effect for a long duration due to its active metabolite, N-desmethylclobazam. Dosage is between 5 mg and 40 mg a day, depending on patient weight, efficacy, and tolerability. Efficacy tolerance has not been a problem in the best studies. Clobazam has provided many benefits to epileptic patients. It should be used by clinicians early as an adjuvant therapy in the treatment of refractory epilepsy and even considered as monotherapy in a broad spectrum of epilepsy syndromes.

    Full Text Available The present work documents the diversity of mammals in the headwaters of the Apurímac river, one of the most important information gaps in Peru, based on an evaluation of fi ve sampling areas in the departments of Apurímac (Cconoc, Velavelayoc, Ayacucho (Yanamonte, Ccentabamba and Cuzco (Catarata. Capture’s effort was 1280 trap-nights and 41 mistnet-nights. Sixty species were recorded in the study area and included 15 threatened species and four species endemic to Perú. As expected, bats and rodents were the most diverse orders (66,7 %. The species diversity in the sites sampled declines signifi cantly with elevation from the lowest elevation sites (Ccentabamba and Catarata to the highest (Velavelayoc. The marsupial Monodelphis peruviana and the Dwarf Brocket deer Mazama chunyi are fifi rst records for the department of Ayacucho. The bats Artibeus planirostris and Myotis keaysi, and the river otter Lontra longicaudis are fifi rst records for the department of Apurímac. For bats, the relative abundance showed a signifi cant negative correlation with elevation, but was not signifi cant for small terrestrial mammals. The species of Sturnira, Akodon and Thomasomys had the highest values of relative abundance. The diversity indices (Shannon-Wiener and Simpson also showed also a signifi cant negative correlation with elevation. The Apurímac river headwater is estimated to have at least 97 mammals species. We recommend creating conservation areas in Huanipaca, Yanamonte and Catarata, and enlarging the area of the Santuario Histórico Machu Picchu to include the archaeological site of Choquequirao.

    In this work, we attempt to capture patterns of co-occurrence across vowel systems and at the same time figure out the nature of the force leading to the emergence of such patterns. For this purpose we define a weighted network where the vowels are the nodes and an edge between two nodes (read vowels) signify their co-occurrence likelihood over the vowel inventories. Through this network we identify communities of vowels, which essentially reflect their patterns of co-occurrence across languages. We observe that in the assortative vowel communities the constituent nodes (read vowels) are largely uncorrelated in terms of their features and show that they are formed based on the principle of maximal perceptual contrast. However, in the rest of the communities, strong correlations are reflected among the constituent vowels with respect to their features indicating that it is the principle of feature economy that binds them together. We validate the above observations by proposing a quantitative measure of percep...

  8. A confident call to faith: Rediscovering the relevance of Christian catechisms

    2013-06-01

    Full Text Available Protestant heritage is synonymous with the traditional employment of catechisms and catechetical teaching of both young and old. Many denominations have shifted from this historical approach, not least because of the challenges of so-called catechetical vacuums when facing third-millennial issues. The Heidelberg, Anglican and Westminster Catechisms allow for express distinctions peculiar to each unique Protestant faith constituency, but serve acceptably within the wider ecumenical tradition. A rediscovery of the historical contexts of these historical formulations will illustrate traditional denominational Protestant flexibility accompanying its Christian creedal fixity. This study will refer to confessional content in the main without resorting to particular content. The intention is to show how these polarities could dynamically serve the confessing church in meeting present-day challenges to the Christian faith in a manner that once again will inspire confidence in its catholic witness in the third millennium.Die protestantse erfenis is sinoniem met die tradisionele gebruik van die kategismusse en die kategetiese onderrig van oud en jonk. Baie kerkgenootskappe neig weg van hierdie historiese benadering hoofsaaklik as gevolg van die uitdagings van die sogenaamde kategetiese leemtes in die hantering van derde millenniumkwessies. Die Heidelbergse, Anglikaanse en Westminsterse Kategismusse laat ruimte vir spesifieke onderskeidings wat eie is aan elke unieke protestantse geloofsgemeenskap, maar wat nogtans binne die breër ekumeniese tradisie aanvaar word. ’n Herontdekking van die historiese konteks van hierdie tradisionele formulerings sal tradisioneel kerklik-protestantse buigsaamheid illustreer wat met konfessionele vastheid gepaard gaan. Hierdie artikel verwys na konfessionele inhoud oor die algemeen sonder om spesifieke inhoud aan te toon. Die doel is dus om aan te toon hoedanig hierdie polariteite die belydende kerk daadwerklik kan help om die daaglikse uitdagings van die Christelike geloof op so ’n wyse te hanteer dat daar weer vertroue in die algemene getuienis van die kerk in die derde millennium sal wees.

  13. Identity, influence, and change: rediscovering John Turner's vision for social psychology.

    Science.gov (United States)

    Haslam, S Alexander; Reicher, Stephen D; Reynolds, Katherine J

    2012-06-01

    John Turner, whose pioneering work on social identity and self-categorization theories changed the face of modern social psychology, died in July 2011. This unique virtual special issue celebrates Turner's life and work by reproducing a number of key articles that were published in the British Journal of Social Psychology and the European Journal of Social Psychology over the course of his career. These articles are of three types: first, key position papers, on which Turner was the leading or sole author; second, papers that he published with collaborators (typically PhD students) that explored key theoretical propositions; third, short commentary papers, in which Turner engaged in debate around key issues within social psychology. Together, these papers map out a clear and compelling vision. This seeks to explain the distinctly social nature of the human mind by showing how all important forms of social behaviour - and in particular, the propensity for social influence and social change -are grounded in the sense of social identity that people derive from their group memberships. As we discuss in this editorial, Turner's great contribution was to formalize this understanding in terms of testable hypotheses and generative theory and then to work intensively but imaginatively with others to take this vision forward.

    Full Text Available This article systematizes a series of moments built while in the company of a fourth grader from the public school where I worked as a special education teacher in 2013. In the article, I described what I learned from the shared experiences generated from the naturalistic paradigm, the qualitative approach and the action research model, using pedagogical situations planned with the objective of understanding the reality of the student and the educational process for this particular case allowing or limiting success at school. My purpose is to reflect on issues related to the educational practice, from an individual standpoint and from the perspective of the teacher who observes and listens to his/herself in his/her daily actions and who looks for new ways to help students to find the true meaning of learning. From this perspective, the methodological design for this research project is based on the natural observation of the interaction between the teacher and the student.  Using this technique allowed identifying one of the participating subjects and choosing research activities (individual or group work sessions and strategies for data collection (photos, videos, stories and conversation recordings. After this, experiences are systematized in written and illustrated form (conversations and photographs of the participant’s drawings. The article is based on a case study that includes my individual interventions with the student, as well as planned learning moments with his class. To conclude, I interpret and analyze each of the moments meeting with the student, in the light of the scientific and theoretical findings accompanying the research project.  In addition, I reflect that my priority as a teacher in action is creating spaces that would allow students to experience sensitivity, empathy, and appreciation for people and their talents.

  16. Rediscovering Einstein's legacy: How Einstein anticipates Kuhn and Feyerabend on the nature of science.

    Science.gov (United States)

    Oberheim, Eric

    2016-06-01

    Thomas Kuhn and Paul Feyerabend promote incommensurability as a central component of their conflicting accounts of the nature of science. This paper argues that in so doing, they both develop Albert Einstein's views, albeit in different directions. Einstein describes scientific revolutions as conceptual replacements, not mere revisions, endorsing 'Kant-on-wheels' metaphysics in light of 'world change'. Einstein emphasizes underdetermination of theory by evidence, rational disagreement in theory choice, and the non-neutrality of empirical evidence. Einstein even uses the term 'incommensurable' specifically to apply to challenges posed to comparatively evaluating scientific theories in 1949, more than a decade before Kuhn and Feyerabend. This analysis shows how Einstein anticipates substantial components of Kuhn and Feyerabend's views, and suggests that there are strong reasons to suspect that Kuhn and Feyerabend were directly inspired by Einstein's use of the term 'incommensurable', as well as his more general methodological and philosophical reflections.

    2017-06-01

    Technology, viewed more generally, is a collection of skills and methods that are used to accomplish an objective of some kind. Modernity has produced many kinds of ever-expanding new technologies, but it is also evident that technologies can be lost or fall out of use. A cross-cultural survey of ritual reveals a rather startling observation: that while developed nations often exceed other cultures in terms of material technology, they often pale by comparison in their use of ritual technology. In this essay we will see how ritual is a powerful sort of technology that developed nations have mostly allowed to drift out of regular, vigorous use, despite its numerous psychological and biological effects. This tendency has left one of the rituals we still have - psychotherapy itself - to be bereft of some of the typical tools for concretizing the symbolic in recurrent patterns around the world. Jung himself could be accused of being somewhat anti-ritual himself, enmeshed as he was in the post-Protestant, post-Enlightenment cultural environment that defines the West in many ways. But these under-utilized elements of ritual technology may be a natural fit for Jungian therapy due to its use of symbols. © 2017, The Society of Analytical Psychology.

  18. Rediscovering the Concept of Asylum for Persons with Serious Mental Illness.

    Science.gov (United States)

    Lamb, H Richard; Weinberger, Linda E

    2016-03-01

    Treating persons with serious mental illness is a complex and challenging endeavor. One intervention that has received little attention in recent years is the need for asylum. Asylum means a sanctuary, a place that lowers levels of stress and provides protection, safety, security, and social support, as well as an array of treatment services. The concept of "asylum" may have lost favor because it was equated with the abysmal conditions found in the state psychiatric hospitals of the past. Among the reasons persons with serious mental illness have been arrested and incarcerated is society's failure to provide adequate levels of asylum. With the release of tens of thousands of mentally ill inmates from state and federal jails and prisons, it is time to revisit this concept, not only for these persons but for those who have not been criminalized. Asylum can be found in various settings, including with family in the patient's home, in a board-and-care facility, or in a psychiatric hospital if necessary. Not all persons with a major mental illness are capable of achieving high levels of social and vocational functioning; however, living in a place that provides asylum can promote a higher quality of life. The value of asylum for many persons with serious mental illness should not be underestimated.

  20. Meeting the Next Generation Science Standards Through "Rediscovered" Climate Model Experiments

    Science.gov (United States)

    Sohl, L. E.; Chandler, M. A.; Zhou, J.

    2013-12-01

    Since the Educational Global Climate Model (EdGCM) Project made its debut in January 2005, over 150 institutions have employed EdGCM software for a variety of uses ranging from short lab exercises to semester-long and year-long thesis projects. The vast majority of these EdGCM adoptees have been at the undergraduate and graduate levels, with few users at the K-12 level. The K-12 instructors who have worked with EdGCM in professional development settings have commented that, although EdGCM can be used to illustrate a number of the Disciplinary Core Ideas and connects to many of the Common Core State Standards across subjects and grade levels, significant hurdles preclude easy integration of EdGCM into their curricula. Time constraints, a scarcity of curriculum materials, and classroom technology are often mentioned as obstacles in providing experiences to younger grade levels in realistic climate modeling research. Given that the NGSS incorporates student performance expectations relating to Earth System Science, and to climate science and the human dimension in particular, we feel that a streamlined version of EdGCM -- one that eliminates the need to run the climate model on limited computing resources, and provides a more guided climate modeling experience -- would be highly beneficial for the K-12 community. This new tool currently under development, called EzGCM, functions through a browser interface, and presents "rediscovery experiments" that allow students to do their own exploration of model output from published climate experiments, or from sensitivity experiments designed to illustrate how climate models as well as the climate system work. The experiments include background information and sample questions, with more extensive notes for instructors so that the instructors can design their own reflection questions or follow-on activities relating to physical or human impacts, as they choose. An added benefit of the EzGCM tool is that, like EdGCM, it helps illustrate the process of doing research on a complex topic, in a way that builds upon earlier experiences in inquiry-based learning. By having students work through a multi-stage process that requires them to plan several steps ahead, through data processing, analysis and interpretation, they learn how to do research in addition to improving their understanding of climate change.

    Full Text Available In a period witnessing the increasing popularity of superhero franchises, comic book historian Tim Hanley sheds light on the forgotten history of the world’s most famous female superhero, Wonder Woman. Tim Hanley’s Wonder Woman Unbound: The Curious History of the World’s Most Famous Heroine, as its title suggests, aims to explore the curious path of Wonder Woman: from the creation of the character to her contemporary iconic status. The book is comprised of three sections that follow the eras of American comic books: Golden Age, Silver Age and Bronze Age. Hanley starts off with Wonder Woman’s origin story, associating it primarily with the life and work of her creator, psychologist William Marston. The story begins when an American pilot, Steve Trevor, crashes on the hidden Paradise Island and is found injured by Diana and her fellow Amazons. Paradise Island is the home of mythical Amazons guided by goddesses Aphrodite and Athena. Their world is an only-female utopia situated far away from the outside, violent, world of men. However, while Amazons live in peace, the outside world is bursting with war and Steve needs to return to America to fulfill his soldier duties. The Amazon goddesses decide to send a warrior, Diana, to help Steve through his journey. That warrior later becomes a superheroine known by the name of Wonder Woman.

    2002-01-01

    Full Text Available This paper focuses on rites of passage as a model for wilderness programs. It draws on my experience in the field, particularly with Native youth in a community-based program called "Rediscovery." The Rediscovery program is discussed, along with concepts of traditional indigenous knowledge and education. Foundational concepts of rites of passage are described in terms of their relevance to youth, outdoor education, and the Rediscovery program in particular. Using Rediscovery as a model, rites of passage are put forward as an educational process for youth from various cultural backgrounds. In this context, the purpose of education is to cultivate self-knowledge and to foster core personal development: the making of whole human beings. The paper closes with a reflection on my work with traditional indigenous people and the significance of rites of passage for education, cultural transformation, and the transition to ecological sustainability.

    How much time spend in Nature the average man? And how much time men spend in the virtual world? Can we consider this one of the main issues when mourning the growing devastating input coming from human activities on the environment? This preliminary work on the theme collect some ideas on the issue and prospect some solution to the light of the work already done in the past. Starting from data collected from the web describing the impact of technology on everyday life, and passing through some studies concerning the impact of technology on the human brain, a new way of conceiving Earth education takes inspiration from a cross cutting of ideas and results coming from different disciplines describing the contemporary world.

  4. Conflict between genetic and phenotypic differentiation: the evolutionary history of a 'lost and rediscovered' shorebird.

    Directory of Open Access Journals (Sweden)

    Frank E Rheindt

    Full Text Available Understanding and resolving conflicts between phenotypic and genetic differentiation is central to evolutionary research. While phenotypically monomorphic species may exhibit deep genetic divergences, some morphologically distinct taxa lack notable genetic differentiation. Here we conduct a molecular investigation of an enigmatic shorebird with a convoluted taxonomic history, the White-faced Plover (Charadrius alexandrinus dealbatus, widely regarded as a subspecies of the Kentish Plover (C. alexandrinus. Described as distinct in 1863, its name was consistently misapplied in subsequent decades until taxonomic clarification ensued in 2008. Using a recently proposed test of species delimitation, we reconfirm the phenotypic distinctness of dealbatus. We then compare three mitochondrial and seven nuclear DNA markers among 278 samples of dealbatus and alexandrinus from across their breeding range and four other closely related plovers. We fail to find any population genetic differentiation between dealbatus and alexandrinus, whereas the other species are deeply diverged at the study loci. Kentish Plovers join a small but growing list of species for which low levels of genetic differentiation are accompanied by the presence of strong phenotypic divergence, suggesting that diagnostic phenotypic characters may be encoded by few genes that are difficult to detect. Alternatively, gene expression differences may be crucial in producing different phenotypes whereas neutral differentiation may be lagging behind.

  12. "Let's take back our roots through Science". The Sicilian Sulfur: a mineralogical treasure to rediscover.

    Science.gov (United States)

    Parisi, Bianca

    2015-04-01

    The name of sulfur is synonymous of Sicily! Sicilian Sulfur minerals and evaporitic deposits are well-known because they are connected with an important evolution stage of the old mediterranean area. In this Island, in the southern part of Italy, a geological formation of Messinian age, called "gessoso solfifera", outcrops. These rocks are widespread in the south and south-west Sicily, and, there, salt mines and "zolfare", sulfur mines, were located. The formation is characterized by large amounts of gypsum, potassium salts, sodium chlorates and other deposits. Most of the main mineralogical museum collections all over the world have at least a sample of one of these minerals that are usually characterized by a high aesthetic quality. When I proposed a lesson on the origin of sulfur in evaporitic rocks, I realized that an important part of the hystory of our region was in danger to be forgotten by younger generation. The exploitation of this mineral resource in the past is strictly linked to the troubled social and cultural transformation of Sicily during the last century. Thus, this is a particularly suitable topic for a multidisciplinary approach. In cooperation with the Mineralogical Museum (SteBiCeF Department, University of Palermo), a learning project was proposed to a group of 4th year high school students. It has been carrying on in order to develop the knowledge of the geological and chemical features of evaporitic deposits and to promote scientific abilities together with a better understanding of social-environmental issues. Project aims and activities include: ➢ Solubility and saturation experiments to reconstruct a simplified model of minerals deposition ➢ Working in groups: collection of data about old geological outcrops and current evaporating basins where rocks are forming in the world as well as information on sicilian mines from literature and historical documents (video, interviews, pictures, newspapers and others) ➢ a guided tour of the Mineralogical Museum and participation to laboratory activities, especially focussing on the identification of sulfates and chlorates minerals and on the observation of samples of different kind of rocks coming from the outcropping areas. ➢ a trip to the Floristella Geopark, instituted on the area of one of the oldest sulfur mine and most eloquent site of industrial archeology and scenario of the fighting for the workers' social rescue. The project can be experienced as a virtual journey through the geological time but also as a dramatic picture of the hard working conditions into the mines. Students are motivated and engaged to learn about geological processes using their whole scientific competences. Nevertheless, expected learning outcomes will be the final awareness to manage responsibly natural resources, even because of the strong impact on social daylife. That's we can definitely say how to take back our roots through Science!

  13. Rediscovering leaf optical properties: New insights into plant acclimation to solar UV radiation.

    Barnes, Paul W; Flint, Stephan D; Ryel, Ronald J; Tobler, Mark A; Barkley, Anne E; Wargent, Jason J

    2015-08-01

    The accumulation of UV-absorbing compounds (flavonoids and other phenylpropanoid derivatives) and resultant decrease in the UV transmittance of the epidermis in leaves (TUV), is a primary protective mechanism against the potentially deleterious effects of UV radiation and is a critical component of the overall acclimation response of plants to changing UV environments. Traditional measurements of TUV were laborious, time-consuming and destructive or invasive, thus limiting their ability to efficiently make multiple measurements of the optical properties of plants in the field. The development of rapid, nondestructive optical methods of determining TUV has permitted the examination of UV optical properties of leaves with increased replication, on a finer time scale, and enabled repeated sampling of the same leaf over time. This technology has therefore allowed for studies examining acclimation responses to UV in plants in ways not previously possible. Here we provide a brief review of these earlier studies examining leaf UV optical properties and some of their important contributions, describe the principles by which the newer non-invasive measurements of epidermal UV transmittance are made, and highlight several case studies that reveal how this technique is providing new insights into this UV acclimation response in plants, which is far more plastic and dynamic than previously thought.

    Full Text Available En este artículo nos referimos al interés de los Emberá (un grupo indígena Amerindio en adquirir conocimientos de los restos materiales del pasado - como fragmentos cerámicos coloniales y prehispánicos - que se encuentran fácilmente en el Panamá Oriental. Situamos el interés de los Emberá (y su deseo de aprender más del pasado en el contexto del turismo indígena, que ha inspirado la articulación de nuevas narrativas sobre la historia e identidad de los Emberá. Adicionalmente, el descubrimiento accidental por los Emberá de restos materiales de períodos pasados ha instigado y facilitado la investigación arqueológica, un proceso que ha resultado en el intercambio recíproco de conocimientos entre los Emberá e investigadores académicos. Argumentamos aquí que esta relación recíproca puede contribuir a la descolonización de la arqueología, crear sinergias entre la antropología y la arqueología e incrementar la representación indígena en el turismo.

  17. Rediscovering the chick embryo as a model to study retinal development

    Directory of Open Access Journals (Sweden)

    Vergara M Natalia

    2012-06-01

    Full Text Available Abstract The embryonic chick occupies a privileged place among animal models used in developmental studies. Its rapid development and accessibility for visualization and experimental manipulation are just some of the characteristics that have made it a vertebrate model of choice for more than two millennia. Until a few years ago, the inability to perform genetic manipulations constituted a major drawback of this system. However, the completion of the chicken genome project and the development of techniques to manipulate gene expression have allowed this classic animal model to enter the molecular age. Such techniques, combined with the embryological manipulations that this system is well known for, provide a unique toolkit to study the genetic basis of neural development. A major advantage of these approaches is that they permit targeted gene misexpression with extremely high spatiotemporal resolution and over a large range of developmental stages, allowing functional analysis at a level, speed and ease that is difficult to achieve in other systems. This article provides a general overview of the chick as a developmental model focusing more specifically on its application to the study of eye development. Special emphasis is given to the state of the art of the techniques that have made gene gain- and loss-of-function studies in this model a reality. In addition, we discuss some methodological considerations derived from our own experience that we believe will be beneficial to researchers working with this system.

    Directory of Open Access Journals (Sweden)

    Dean, Edward

    2016-10-01

    Full Text Available This paper argues that despite contemporary discoveries disproving Cartesian mind-body dualism – which falsely presupposed a separation between mind and body – contemporary performances of mentalism are still vastly impacted by this belief. I further argue that the long-supposed divide between mind and body has led many contemporary mentalists to underexplore and underemphasize bodies in performance, particularly their own. In the exploration of this topic, I examine notions of psychophysical acting and post-Cartesian character – in relation to the personas cultivated and projected by mentalists – proposing the terms metamentalism, inverse method acting, quasi-character, and anti-character to better capture the forms of role play and persona variously taken on and projected by mentalists. I next examine the archetype of the trickster as it relates to mentalists, including associations with shamans and buffoons. I conclude with an examination of the material properties of mentalism.

    A 14-year-old boy came to our outpatient department with pleuritic chest pain and dyspnea. He was found to have a loculated empyema on the right side. He was taken up for surgery and decortication was done. He developed air leak in the postoperative period. When the air leak did not settle until the 10th day, we decided to attach the atrium Pneumostat™, a modified version of the Heimlich valve to his Intercostal drainage tube and sent him home. On further follow-up, his lung expanded, and ICD could be removed. The patient remains well until the current follow-up. We present this case in an attempt to change the perceptions about various options available to drain the chest. The Heimlich valve appears to be a more compliant option than the conventional underwater seal drainage in terms of early mobility, reduced length of stay, and patient compliance. PMID:28144064

  1. Cycle Tourism in Olt County, Romania. (ReDiscovering Potential of History and Geography for Tourism

    Directory of Open Access Journals (Sweden)

    Viorel Mionel

    2016-11-01

    Full Text Available Olt is among Romania's counties that remains hidden when it comes to tourism. Unlike other Romania's counties that possess tourism advantages in the form of landscape or anthropic heritage, Olt county appears to lack the first part. However, the landscape is developed on a wavy morphology with not so crowded roads that favours cyclotourism. Therefore, the analysis focused on highlighting the historical-geographic objectives with touristic potential, as well as turing them to good account in the form of cycle routes. The novelty of the research is to design four cycle routes using Strava app and choosing a county in the lowlands as a case study. At the time of this analysis cycle tourism in Olt county, there was only one route for cyclists, currently online, but without no touristic importance. The methodology used involved identifying historical and geographical ob jectives of national importance, structuring categories and grouping them into four mixed tracks which were dedicated to cyclists. Previous stages were followed by field research in order to collect technical data (map, time, distance, total ascent etc.. Finally, a critical review of proposed bicycle routes was undertaken in the research. Study results showed that cycling tourism is a real opportunity for Olt county economy thanks to the number and value of the present tourism potential objectives. Nevertheless, at this stage, the lack of infrastructure, promotion and the small number of units makes it difficult to organize cycle tourism. What is more, the lack of cycle paths endangers cyclotourists’ safety.

  2. Rediscovering hermaphroditism in Grammatidae with the description of the testicular gland in Brazilian Basslet Gramma brasiliensis

    Directory of Open Access Journals (Sweden)

    J. R. Leite

    Full Text Available Abstract Many aspects of sex change in reef fishes have been studied, including behavior and social organization. However, gonad histology remains the most robust way to identify sexual patterns in fishes. Some uncommon tissues remain poorly described, such as the accessory gonadal structures found in species from the Gobiidae family, which are rare in other bony fishes. This is the first report of the testicular gland in Gramma brasiliensis and for the Grammatidae family. Between April 2011 and February 2012 eighty specimens were collected during four dive campaigns on the Taipus de Fora reef (13°56’20”S 38°55’32”W, Bahia, Northeast Brazil, and their sex was determined. Thirteen per cent of the active-females and 90% of the active-males had testicular gland tissue in their ovotestis. This discovery led to additional research into the characteristics of the gland tissue and its relationship with gonadal maturation. Three patterns of testicular gland development were found in Brazilian basslet ovotestis. Both ova and sperm-producing gonad contained testicular gland tissue, and the appearance of this tissue seems to be the first modification of ovotestis tissue marking the beginning of the protogynous sex-change process in G. brasiliensis.

    In this article, I review the empirical status of the Rorschach as it relates to potential use of the instrument in personnel selection procedures. As part of this review, I outline developing trends in personnel selection practices, discuss the Rorschach literature relevant to organizational performance, and weigh the benefits and drawbacks of using the instrument in this capacity. Based on this analysis, I argue that the Rorschach may represent a unique and potentially valuable tool for assessing personality as part of comprehensive personnel selection procedures. I conclude with a proposed trajectory for Rorschach research intended to better determine the instrument's viability in organizational settings.

    Davis, Deborah L; Walker, Kim

    2010-08-01

    The body is of central concern to midwifery yet, as a profession, we have largely failed to grapple with the corpus of feminist and other literature that deals with the body. This article provides an overview of the ways in which the body has been theorised, from the essential and biological through to postmodern theories of the body. We draw attention to the limitations of some of these approaches, suggesting that Elizabeth Grosz's schema of the Möbius strip (representing the inter-relationships between the inside and outside, culture and nature) provides a useful framework for thinking about the body; one that avoids a biological materialism that disregards the effect of culture, and a cultural determinism that neglects the corporeal body. Recognising the multiplicity and fluidity of women's experiences of pregnancy, their body and childbearing emancipates us from the limitations imposed by the masculinist Western philosophical traditions that we have inherited.

  6. Kidney biomimicry--a rediscovered scientific field that could provide hope to patients with kidney disease.

    Stenvinkel, Peter; Johnson, Richard J

    2013-11-01

    Most studies on kidney disease have relied on classic experimental studies in mice and rats or clinical studies in humans. From such studies much understanding of the physiology and pathophysiology of kidney disease has been obtained. However, breakthroughs in the prevention and treatment of kidney diseases have been relatively few, and new approaches to fight kidney disease are needed. Here we discuss kidney biomimicry as a new approach to understand kidney disease. Examples are given of how various animals have developed ways to prevent or respond to kidney failure, how to protect themselves from hypoxia or oxidative stress and from the scourge of hyperglycemia. We suggest that investigation of evolutionary biology and comparative physiology might provide new insights for the prevention and treatment of kidney disease. Copyright © 2013 IMSS.

    2009-12-01

    It is estimated that half of the world's population now live in urban environments. Urban living necessitates a removal from nature, yet evidence indicates that contact with nature is beneficial for human health. In fact, everyday urban places, such as where people live, study, and work, provide opportunities to bring nature back into cities to contribute to positive, healthy environments for people and to foster the human-nature connection. The inclusion of more nature in cities could have additional environmental benefits, such as habitat provision and improving the environmental performance of built environments. In the context of climate change, outcomes such as these assume further importance. This article explores how common urban places can foster links between people and nature, and generate positive health and well-being outcomes. We achieve this by exploring nature in the everyday settings of schools and residential housing.

    Buckwheat whole plant can be used for the production of biogas. Due to its short growing period, buckwheat can be integrated very variable in crop rotations. For example, buckwheat can be grown as a second crop in the summer. After the harvest of winter wheat, which is used as whole plant silage, the sowing date is around mid-June. The ingredients of buckwheat expect a good fermentability with corresponding biogas production. [German] Buchweizen-Ganzpflanzen koennen fuer die Erzeugung von Biogas genutzt werden.

    Middleton, Beth A.

    2013-01-01

    Land managers are grappling with massive changes in vegetation structure, particularly in protected areas formerly subjected to fire and grazing. The objective of this review was to compare notes on the historical and current management of ecosystems around the world (especially in wet to dry grasslands in the Americas, Australia, Africa, Europe and Asia) with respect to the usage of fire, grazing and cutting to reduce dominance and support the biodiversity of rare species. This review suggests that former disturbances, which are now often lost, may have once kept tall vegetation from pushing out rarer subdominant species. In cases where prehistoric biodiversity depended on fire or large ungulate grazing, traditional agricultural and indigenous practices may have carried biodiversity forward to historical times by mimicking pre-cultural disturbances (e.g., lightning fire and bison grazing). Ironically, biodiversity related to species richness, landscape heterogeneity and function may decline in preserves, especially if traditional management once maintained this biodiversity. Managers can benefit from a cross-continental comparison of the full arsenal of management techniques used to control encroaching vegetation.

    2014-06-01

    This paper deals about astronomical orientation of Incas objects in Ollantaytambo, which is located about 35 km southeast from Machu Picchu, about 40 km northwest from Cusco, and lies in the Urubamba valley. Everybody writing about Ollantaytambo, shoud read Protzen (1993). He devoted his monograph to description and interpretation of that locality. Book of Salazar and Salazar (2005) deals, among others, with the orientation of objects in Ollantaytambo with respect to the cardinal direction. Zawaski and Malville (2007) documented astronomical context of major monuments of nine sites in Peru, including Ollantaytambo. We tested astronomical orientation in these places and confirm or disprove hypothesis about purpose of Incas objects. For assessment orientation of objects we used our measurements and also satellite images on Google Earth and digital elevation model from ASTER. The satellite images used to approximate estimation of astronomical orientation. The digital elevation model is useful in the mountains, where we need the really horizon for a calculation of sunset and sunrise on specific days (solstices), which were for Incas people very important. By Incas is very famous that they worshiped the Sun. According to him they determined when to plant and when to harvest the crop. In this paper we focused on Temple of the Sun, also known the Wall of six monoliths. We tested which astronomical phenomenon is connected with this Temple. First, we tested winter solstice sunrise and the rides of the Pleiades for the epochs 2000, 1500 and 1000 A.D. According with our results the Temple isn't connected neither with winter solstice sunrise nor with the Pleiades. Then we tested also winter solstice sunset. We tried to use the line from an observation point near ruins of the Temple of Sun, to west-north, in direction to sunset. The astronomical azimuth from this point was about 5° less then we need. From this results we found, that is possible to find another observation

  19. Trigger Analysis and Modelling of Very Large Debris Flows in Santa Teresa, Cusco, Southern Peru

    Buis, Daniel; Huggel, Christian; Frey, Holger; Giráldez, Claudia; Rohrer, Mario; Christen, Marc; Portocarrero, César

    2014-05-01

    The Peruvian Andes have repeatedly been affected by large mass movements such as landslides, avalanches and debris flows. In 1998, two very large debris flows in the region of Machu Picchu (Sacsara and Ahobamba), southern Peru, destroyed the town of Santa Teresa, an important hydropower scheme and further infrastructure. The debris flows on the order of 5 to 25 million m3 volume rank among the largest recently observed events of this type worldwide. Despite their extreme dimensions, these events have not been studied in detail. An important limitation for more insight studies is the remote location of the mass flows and the very sparse information and data available for the study region. Neither triggering processes nor mass flow process characteristics have been understood to date. This study tries to fill some of these gaps in understanding that are critical to improved assessment of hazards and eventual risk reduction measures. For the trigger analysis we used data and information from field work, a limited number of ground based meteorological data, and complementary satellite derived data. Results indicate that in the case of the Sacsara event, heavy rainfall likely was a main trigger. For Ahobamba, antecedent rainfall as well as snow and ice melt leading to saturation of glacial sediments must have played an important role. Simulations with a dynamic debris flow model (RAMMS) allowed us to constrain a number of flow parameters such as flow height and velocity, runout distance and flow and deposition volumes. Strong surging flow behavior was detected, resulting in very large runout distance (exceeding 20 km); which rather depends on the largest single surge volume, not the total event volume. Based on the identification of potential mass flow sources we modeled a number of scenarios. The assessment of related hazards, including a preliminary hazard map, showed that several communities in catchments draining towards Santa Teresa are endangered by mass movements

    The Andes of Peru are among the regions most severely affected by glacier and high-mountain hazards over the past 100 years. Large-scale disasters with thousands of people killed are on record, including ice/rock avalanches, debris flows, and glacier lake outburst floods (GLOF's). Effects of climate change such as glacier retreat and formation of glacier lakes have been one of the drivers of hazards in the past. Now, there is an increasing concern about the destabilizing effect that recent and further warming has a on perennially frozen bedrock and on steep glaciers in the steep flanks of high-mountain peaks, with potentially severe consequences to ice/rock avalanches, which may impact existing and new lakes, producing far-reaching outburst floods. Risks are also changing due to the socio-economic development in the Andean region and need to be considered using integrative approaches. Most research so far has concentrated on the Cordillera Blanca region where the most devastating disasters occurred during the 20th century. Very little is known about glacier and high-mountain hazards in the southern Peruvian Cordilleras of Cusco although some of the largest debris flows worldwide affected this region in recent years. In fact, very little is known about the nature, origin and exact dimensions of mass movements in this area, and long-term climatic records are neither available. Here we analyze these recent events in the Santa Teresa region based on field work, satellite images, available meteorological data, and numerical modeling of mass movements. These studies are part of a larger effort towards an integrative risk management. Most of the mass movements that caused disasters have their origin in glaciated catchments draining towards Santa Teresa with catchment sizes between about 100 and 300 km2, and glacier areas of 6 to 16 km2 per catchment. It is known that the enormous 1998 debris flow (ca. 25 million m3) that destroyed the Machu Picchu hydropower plant

    President Manuel Pachecho recognized Ray's extensive contributions by asking him to serve as Master of Ceremonies at the University commencement. Ray White's research career was not as extensive as his teaching activities, but it was creative. His original specialty was globular star clusters and classes of variable stars within them. He made several catalogs of star clusters and associations, measured the exact centers, the axial ratios and the orientations of around 100 Galactic globular clusters. Certainly, Ray's greatest love in research, especially in later years, was archaeoastronomy. He studied the evidence for astronomical observations of the Sun, Moon and stars from the mound sites of the prehistoric Hohokam inhabitants of the Salt River Valley of Arizona. He was best known for his studies of the Inkaic people of the pre-Columbian, Peruvian Andes. Most of this research involved the grand Machu Picchu site, where he showed (with David Dearborn) that the central tower (the "Torreon") certainly had been used as an Observatory. They also discovered a separate, solstice observatory and named it Intimachay. Characteristically, Ray combined much of his archaeoastronomy research interests with the involvement of undergraduate students and adults through the Earthwatch program in field trips to Machu Picchu. With a Professor in the humanities who was also well known at the University of Arizona, Donna Swaim, Ray introduced a group of undergraduates in summer classes to several archaeoastronomy sites in such countries as Ireland and the British isles. Of course they also gave on-site lectures at art museums, and sites of historical and cultural interest. Like many astronomers, Ray was well traveled. He had sabbaticals at the University of Cambridge in 1980, and at the Dublin Institute of Advanced Study (Dunsink Observatory), Ireland, in 1996-97. The latter was funded by his winning a Fulbright Fellowship, which enabled him to further his studies of the Celtic astronomical

    We present a detailed optical and X-ray study of the 2013 outburst of the Small Magellanic Cloud Be/X-ray binary SXP 7.92, as well as an overview of the last 18 years of observations from OGLE, RXTE, Chandra and XMM-Newton. We revise the position of this source to RA(J2000)=00:57:58.4, Dec(J2000)=-72:22:29.5 with a 1σ uncertainty of 1.5″, correcting the previously reported position by Coe et al. (2009) by more than 20 arcminutes. We identify and spectrally classify the correct counterpart as a B1Ve star. The optical spectrum is distinguished by an uncharacteristically deep narrow Balmer series, with the Hα line in particular having a distinctive shell profile, i.e. a deep absorption core embedded in an emission line. We interpret this as evidence that we are viewing the system edge on and are seeing self obscuration of the circumstellar disc. We derive an optical period for the system of 40.0±0.3 days, which we interpret as the orbital period, and present several mechanisms to describe the X-ray/Optical behaviour in the recent outburst, in particular the "flares" and "dips" seen in the optical light curve, including a transient accretion disc and an elongated precessing disc.

    Herbal medicines and traditionally used medicinal plants present an untapped potential for novel molecular target discovery using systems science and OMICS biotechnology driven strategies. Since up to 40% of the world's poor people have no access to government health services, traditional and folk medicines are often the only therapeutics available to them. In this vein, North East (NE) India is recognized for its rich bioresources. As part of the Indo-Burma hotspot, it is regarded as an epicenter of biodiversity for several plants having myriad traditional uses, including medicinal use. However, the improvement of these valuable bioresources through molecular breeding strategies, for example, using genic microsatellites or Simple Sequence Repeats (SSRs) or Expressed Sequence Tags (ESTs)-derived SSRs has not been fully utilized in large scale to date. In this study, we identified a total of 47,700 microsatellites from 109,609 ESTs of 11 medicinal plants (pineapple, papaya, noyontara, bitter orange, bermuda brass, ratalu, barbados nut, mango, mulberry, lotus, and guduchi) having proven antidiabetic properties. A total of 58,159 primer pairs were designed for the non-redundant 8060 SSR-positive ESTs and putative functions were assigned to 4483 unique contigs. Among the identified microsatellites, excluding mononucleotide repeats, di-/trinucleotides are predominant, among which repeat motifs of AG/CT and AAG/CTT were most abundant. Similarity search of SSR containing ESTs and antidiabetic gene sequences revealed 11 microsatellites linked to antidiabetic genes in five plants. GO term enrichment analysis revealed a total of 80 enriched GO terms widely distributed in 53 biological processes, 17 molecular functions, and 10 cellular components associated with the 11 markers. The present study therefore provides concrete insights into the frequency and distribution of SSRs in important medicinal resources. The microsatellite markers reported here markedly add to the genetic stock for cross transferability in these plants and the literature on biomarkers and novel drug discovery for common chronic diseases such as diabetes.

    Gregório Lopes (c. 1490-1550) was one of the most prominent painters of the renaissance and Mannerism in Portugal. The painting "Mater Misericordiae" made for the Sesimbra Holy House of Mercy, circa 1535-1538, is one of the most significant works of the artist, and his only painting on this theme, being also one of the most significant Portuguese paintings of sixteenth century. The recent restoration provided the possibility to study materially the painting for the first time, with a multianalytical methodology incorporating portable energy-dispersive X-ray fluorescence spectroscopy, scanning electron microscopy-energy-dispersive spectroscopy, micro-X-ray diffraction, micro-Raman spectroscopy and high-performance liquid chromatography coupled to diode array and mass spectrometry detectors. The analytical study was complemented by infrared reflectography, allowing the study of the underdrawing technique and also by dendrochronology to confirm the date of the wooden panels (1535-1538). The results of this study were compared with previous ones on the painter's workshop, and significant differences and similitudes were found in the materials and techniques used.

    2015-04-01

    Full Text Available In Italy otters occur in two small populations in the South, while in the Alps they have been extinct for about 50 years. In Austria, the species is recovering and re-colonizing the Southern part of the country. The first record of the species in the Italian Alps goes back to 2008, when otters were found in the most upper catchment of the River Drau in the Region Trentino Alto Adige – South Tyrol. In the Region Friuli Venezia Giulia (NE Italy, in 2011 and 2012 two otters were found road killed within the catchment of the River Tagliamento. These findings prompted an otter survey, carried out in spring 2014 along the catchment of the upper Tagliamento and the Italian side of the River Slizza-Gailitz, which drains the area of Tarvisio and joins the River Drau in Austria, near Villach. The survey covered an area of 3200 km2. A total of 138 bridges and 16 stretches of 600 m were checked along the river banks for otter signs, i.e. spraints and tracks. Otter signs were found at 27 of the investigated sites, in the area of Tarvisio along the River Slizza-Gailitz (Drau catchment, but not in the catchment of the Tagliamento. Like for individuals found in Alto Adige – South Tyrol otters living in the area of Tarvisio belong to the River Drau population in Austria.

    2010-01-01

    The recent discovery of the bio-waste and excreta treatment of a former civilisation in the Amazon reveals the possibility of a highly efficient and simple sanitation system. With the end product that was black soil they converted 10% of former infertile soil of the region: Terra Preta do Indio (black soil of the Indians). These soils are still very fertile 500 years after this civilisation had disappeared. Deriving from these concepts, Terra Preta Sanitation (TPS) has been re-developed and adopted. TPS includes urine diversion, addition of a charcoal mixture and is based on lactic-acid-fermentation with subsequent vermicomposting. No water, ventilation or external energy is required. Natural formation processes are employed to transform excreta into lasting fertile soil that can be utilised in urban agriculture. The authors studied the lacto-fermentation of faecal matter with a minimum of 4 weeks followed by vermicomposting. The results showed that lactic-acid fermentation with addition of a charcoal mixture is a suitable option for dry toilets as the container can be closed after usage. Hardly any odour occured even after periods of several weeks. Lactic-acid fermentation alone without addition of bulking agents such as paper and sliced-cut wood to raise the C/N ratio is creating a substrate that is not accepted by worms.

  18. Rediscovering The Great Chichimeca: Regional Assertiveness and Social Anthropology in the Rehabilitation of a Mexican Ethnic Plurality

    Directory of Open Access Journals (Sweden)

    Tomé, Pedro

    2010-06-01

    Full Text Available For centuries Mexicans have used the term “Chichimeca” as a synonym for “Barbarian” or “Savage.” However, in the past decades a deeper understanding of the Chichimeca peoples —largely affected by a political assertiveness of the regions in Mexico— has resulted in a fresh reconstruction of the memory of the Spanish conquest and, thereby, of the view of these peoples. To a unexpected extent, social anthropology —particularly, the “Seminario Permanente de Estudios de la Gran Chichimeca” (SPECH, promoting regular discussions and publications on the subject from different academic disciplines— has contributed to this rehabilitation as well. A convergence is thus emerging between new scholarly interest in the indigenous nations of Mexico’s northern frontier —taking the Chichimeca out of the ostracism to which official history in the country had confined them— and a newly found reason for pride among the rest of the population in belonging to the same area.

    Durante siglos el término “chichimeca” ha sido utilizado por los mexicanos como sinónimo de “bárbaro” o “salvaje”. Sin embargo, en las últimas décadas una profundización en el conocimiento de los grupos chichimecas —a la que no ha sido ajena una re-valorización política de las regiones en México— ha propiciado una nueva reconstrucción de la memoria de la conquista española que, en parte, ofrece una visión distinta de estos grupos humanos. En un grado no previsto, la antropología social —y, en particular, el “Seminario Permanente de Estudios de la Gran Chichimeca” (SPECH, en el que diferentes disciplinas académicas dialogan sobre un mismo tema y un mismo territorio— está contribuyendo a la misma revisión, con el resultado convergente de sacar a los pueblos chichimecas del ostracismo al que la historia oficial en México los había confinado, mientras se genera, entre otros habitantes de esa parte del país, un cierto orgullo de ser del mismo lugar que ellos.

    The local center of Santa Teresa (Cusco Region, Peru, 7 km northwest of the ruins of Machu Picchu) has been affected by several large debris-flow events in the recent past. In January and February 1998, three events of extreme magnitudes with estimated total volumes of several tens of millions cubic meters each, caused the destruction of most parts of the municipality and resulted in a resettlement of the town on higher grounds. Additionally, several settlements further upstream, as well valuable infrastructure such as bridges, a railway, and a hydropower plant, were destroyed. Some events were related to large-scale slope instabilities and landslide processes in glacial sediments that transformed into highly mobile debris flows. However, the exact trigger mechanisms are still not entirely clear, and the potential role of glacial lakes for past and future mass flows remains to be analyzed. Here we applied RAMMS (RApid Mass Movement System), a physically based dynamic model, to reconstruct one of the 1998 events in the Sacsara catchment using the ASTER Global Digital Elevation Model (ASTER GDEM) with 30 m spatial resolution and a photogrammetric DEM compiled from ALOS PRISM data with 6 m spatial resolution. A sensitivity analysis for various model parameters such as friction and starting conditions was performed, along with an assessment of potential trigger factors. Based on these results, further potential debris-flows for this catchment were modeled, including outburst scenarios of several glacial lakes. In combination with a vulnerability analysis, these hazard scenarios were then incorporated in a qualitative risk analysis. To further reduce the risk for the local communities, technical risk sheets were elaborated for each of the 17 local settlements in the catchment. Furthermore an Early Warning System (EWS) has been designed. The modular structure of the EWS aims at a first step to install an inexpensive but efficient system to detect debris-flow type mass

    depend on these water resources but indicate a strong water vulnerability due to a high degree of absolute poverty, 30% and only 67% of access to drinking water. The Vilcanota area has been traditionally the breadbasket for the whole Cusco area. While agriculture is the most important labor sector, a growing export-oriented crop production depends highly on a minimum river streamflow ensuring sufficient water quantity and quality. Hydropower, with 53% of the total electricity nationwide the energy pillar of Peru's economy, might also be heavily affected by diminishing water resources. Nevertheless, improved power plants have to balance out Peru's by 7.5% y-1 increasing energy demand. For instance, the Machu Picchu hydropower plant is currently expanded by 100 MW to a full capacity of 190 MW but does not consider future water availability of the Vilcanota River and local impacts for the population. Our conclusions suggest to focus on an integrative risk-oriented supply-demand water balance model scheme in order to capture the complexity of recent and future water distribution. The integration of both physical and social key variables considering long-term changes in climate-glacier interactions as well as economic and demographic trends, plays a determinant role for the performance quality of that model and future adaptation strategies.

  1. REDISCOVERING MISES-HAYEK MONETARY AND BUSINESS CYCLE THEORY IN LIGHT OF THE CURRENT CRISIS: CREDIT EXPANSION AS A SOURCE OF ECONOMIC BOOM AND BUST

    Directory of Open Access Journals (Sweden)

    Marcin Mrowiec

    2013-10-01

    Full Text Available The article starts with a brief description of Mises’ monetary theory, with emphasis on the Misesian differentiation of two kinds of credit: commodity and circulation credit, and with the description of the impact of circulation credit expansion on the business cycle. Further on it is described how Mises’ insights constituted the kernel of Austrian Business Cycle Theory, and how the same observations on the nature of credit constituted the kernel of the Chicago Plan (though Mises’ views on the nature of credit led him to different conculsions than it led the authors of the Chicago Plan, and how this plan is being “rediscovered” now. The following sections deal with observations of one of the preeminent current macroeconomic researches, Mr. Claudio Borio, on the elasticity of credit as the source of the current crisis, and on the importance of the financial cycle in analysing the current economic crisis. The author of this text demonstrates that Austrian Business Cycle Theory gave the same answer regarding the sources of economic crises that now modern macroeconomic theory seems to be approaching, and that the postulates for successful financial cycle modeling are already included in the ABCT. Finally, some observations on the current crisis, as well as proposals of avenues of further research are proposed.

  2. The re-discovered Maculinea rebeli (Hirschke, 1904: Host ant usage, parasitoid and initial food plant around the type locality with taxonomical aspects (Lepidoptera, Lycaenidae

    Directory of Open Access Journals (Sweden)

    András Tartally

    2014-04-01

    Full Text Available The taxonomy of the myrmecophilous Maculinea alcon group (Lepidoptera: Lycaenidae is highly debated. The host-plant and host-ant usage of these butterflies have conventionally been important in their identification. Maculinea ‘rebeli’ has generally been considered to be the xerophilous form of Ma. alcon (Ma. alcon X hereafter with Gentiana cruciata as initial food plant. However, the type locality and all other known sites of Ma. rebeli are found above the coniferous zone, and are well separated from the lower regions where Ma. alcon X sites are found. Furthermore, no food plant and host ant data for the nominotypic Ma. rebeli have yet been published. Our aim was therefore to identify the host ant(s of Ma. rebeli around the type locality and compare this with the host ant usage of nearby Ma. alcon X. Nests of Myrmica spp. (Hymenoptera: Formicidae close to the host plants were opened on one Ma. alcon X (host plant: Gentiana cruciata and two Ma. rebeli (host plant: Gentianella rhaetica, first record, confirmed by oviposition and emerging larvae sites just before the flying period, to find prepupal larvae and pupae. Three Myrmica species (My. lobulicornis, My. ruginodis, My. sulcinodis were found on the two Ma. rebeli sites, which parasitized exclusively My. sulcinodis (22 individuals in 7 nests. On the Ma. alcon X site Myrmica sabuleti and My. lonae were found, with My. sabuleti the exclusive host (51 individuals in 10 nests. Ichneumon cf. eumerus parasitized both butterflies. The results highlight the differentiation of Maculinea rebeli from Ma. alcon X, from both conservation biological and ecological points of view. Thus, it should be concluded that Ma. rebeli does not simply represent an individual form of Ma. alcon but it can be considered as at least an ecological form adapted to high mountain conditions both in its initial food plant and host ant species. In addition, it should be emphasized that Ma. alcon X (= Ma. rebeli auct. nec Hirschke cannot be synonymised with Ma. rebeli (Hirschke, 1904.

    Full Text Available Physiology, which is often viewed as a field of study distinct from development, is technically defined as the branch of biology that explores the normal function of living organisms and their parts. Because plants normally develop continuously throughout their life, plant physiology actually encompasses all developmental processes. Viewing plant biology from a physiologist’s perspective is an attempt to understand the interconnectedness of development, form, and function in the context of multidimensional complexity in the environment. To meet the needs of an expanding human population and a degrading environment, we must understand the adaptive mechanisms that plants use to acclimate to environmental change, and this will require a more holistic approach than is used by current molecular studies. Grand challenges for studies on plant physiology require a more sophisticated understanding of the environment that plants grow in, which is likely to be at least as complex as the plant itself. Moving the lab to the field and using the field for inspiration in the lab need to be expressly promoted by the community as we work to apply the basic concepts learned through reductionist approaches toward a more integrated and realistic understanding of the plant.

  6. The elephant in the room: The need to re-discover the intersection between poverty, powerlessness and power in ‘Theology and Development’ praxis

    Full Text Available South Africa remains a divided community on many levels: socially, racially and socioeconomically. This is no more evident than in the recent protests – most notably waged on university campuses and on the streets in the past year. This, the article argues, is closely related to the need to reclaim the notion of power by those who feel they remain relegated to the social and economic peripheries after over 20 years of democracy. While ‘theology and development’ praxis has been most closely associated in a post-apartheid era with welfare and charity approaches or pragmatic interaction with state and civil society (both of which have been critiqued, what has not been sufficiently addressed is the notion of power which once dominated ecclesiastical discourses. This is the proverbial ‘elephant in the room’, which the article argues must once again be revisited and re-engaged – both within scholarly reflection and within church practice – in order to address these divides.

  13. We must not forget what we once knew: an exemplar for helping nurses reconnect with their history and rediscover their passion for nursing.

    2010-12-01

    Whether it is adhering to the latest regulatory requirements, measuring performance, evaluating the patient's experience of care, or preventing pressure ulcers, nothing is more vital to the success of any initiative than the requisite skill and observations of a professional nurse. Yet, for many nurses, getting through the day can be a struggle. Feeling overwhelmed, disconnected, and scattered, reshaping the identity and passion once recognized as an individual's "calling" to professional nursing leads to poor outcomes for nurses and patients alike. Nursing was not intended to be such a struggle, and many "new" performance indicators contain elements that have been recognized as proper nursing practice throughout the history of the profession. Nurses must be reminded of their rich history and the teachings of Florence Nightingale. This article summarizes one hospital's experience with a newly developed tool used during nursing orientation. While connecting past and present, both standards and expectations for nursing practice are communicated, leaving nurses feeling supported, validated, and energized.

  14. Rediscovering the palette of Alentejo (Southern Portugal) earth pigments: provenance establishment and characterization by LA-ICP-MS and spectra-colorimetric analysis

    2009-09-01

    Colored earth pigments sourced from Alentejo, Portugal, can be geologically categorized as either weathered carbonate rocks (terra rossas), schist units, or weathered iron ore deposits. The material was used until the mid-1900s by local residents as an ingredient in their traditional lime wash paintings and possibly in the production of artistic murals across the Alentejo region since pre-historic times. An integrated methodology incorporating laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) and spectra-colorimetric analysis (CIELAB coordinates and reflectance curves), complemented by XRD, WDXRF, SEM-EDX, optical microscopy, and granulometric analysis, was used to characterize thirty-one Alentejo colored earths in an effort to correlate provenance with pigments properties. Data obtained from elemental analysis (major and trace) revealed a generic and similar elemental “fingerprint” that unable their distinction according to geographic provenance. Samples of weathered iron ore deposits derived from explored iron, copper, and sulfur mines are more easily discriminated using the chalcophilic (“sulfur-loving“) elements. Color analysis revealed a range of hues; olive-yellow to dark reddish-brown owing mainly to differences in the type and proportion of the color component present, independent of the accessory mineral.

  16. The origins of the plebs Sanctae Agathae. Inscriptions lost and rediscovered on the history of Santhià in the Early Middle Ages

    Directory of Open Access Journals (Sweden)

    Marco Aimone

    2014-04-01

    Full Text Available Two fragments of white marble are embedded in the apsis’ wall outside the parish church of St. Agatha in Santhià (near Vercelli, in Piedmont: the first one is engraved with the final part of a dedicatory inscription to a martyr by a clergyman named Vvalpertus (or Alpertus; the second one is a part of a small pillar or a lintel coming from a presbytery enclosure, and is decorated with a motif of intertwined gallons. The inscription stayed in the middle of a pluteus bordered by a carved frame, of which only a part of the lower band survives: the letters and the style of the decorations allow a chronology within the 8th century, while the fragment of pillar is to be traced back to a period between the 8th and the first half of the 9th. Of special interest are the Lombard onomastic of the dedicator and, in the final surviving text, the “signature” of a sculptor, which is present in a second inscription of Lombard age found in Piedmont, adorned with carved decorations as well. The analysis of these artefacts - hitherto unpublished - offered the opportunity to restudy two other inscriptions once existing in the church of St. Agatha, long lost and of uncertain authenticity: all these data allow various deductions about the history of Santhià over the centuries of the early Middle ages, the presence of a clergy in the countryside of the diocese of Vercelli, and the work of sculptors and engravers active between the 8th and 9th century in an area between Lombardy, Piedmont, Liguria and Provence, labelled in the past under the unifying name of “bottega delle Alpi Marittime”.

  17. ANT XXIV/2 (SYSTCO) Hexactinellida (Porifera) and bathymetric traits of Antarctic glass sponges (incorporating ANDEEP-material); including an emendation of the rediscovered genus Lonchiphora

    Göcke, Christian; Janussen, Dorte

    2011-10-01

    In this study, we present the hexactinellid sponges sampled in the Weddell-Sea during the ANT 24-2 SYSTCO expedition (30.10.2007-31.01.2008) on the RV Polarstern. All deep-sea stations sampled during this expedition showed comparably modest sponge colonization, with Hexactinellida and Demospongiae occurring in similar numbers of species and individuals. The hexactinellids sampled represent three abyssal species and six species from the deep shelf. Among the deep-sea glass sponges one species new to science was found, Lonchiphora antartica sp. nov., belonging to a poorly known genus, so far represented by only a single specimen known from the Sagami Bay, Japan. Herein we give the first detailed emended diagnosis of the genus and a description of the new species representing the genus as its first well-known specimen. Ecological analysis shows three clearly differentiated associations of hexactinellid sponges in the Antarctic Ocean, which replace each other with increasing depths. Sponge communities on the shelf are dominated by Rossella spp., those on the continental slope and in the lower bathyal mostly by Bathydorus spinosus, and the abyssal associations by Caulophacus spp. No distinct geographical distribution pattern of the Weddell-Sea Hexactinellida could be observed, apart from those caused by their bathyal ranges.

  2. Should the definition of "sleep hygiene" be antedated of a century? A historical note based on an old book by Paolo Mantegazza, rediscovered. To place in a new historical context the development of the concept of sleep hygiene.

    Science.gov (United States)

    Gigli, Gian Luigi; Valente, Mariarosaria

    2013-05-01

    The article contains a historical note on the concept of sleep hygiene, developed in 1977 by Peter Hauri, who developed a set of sleep-promoting rules, considered the fundament for sleep-hygiene techniques. Somnologists, unanimously ascribed to Hauri the fatherhood of the lucky term, while numerous books included at least a section on sleep hygiene. "Inadequate sleep hygiene" was included as a nosological entity in the International Classification of Sleep Disorders. This article intends to demonstrate that the concept of sleep hygiene was developed many years before, thanks to the pioneering work of Paolo Mantegazza, a scientist and a professor in the Medical School of the University of Pavia, Italy. After presenting briefly the history of the University of Pavia and illustrating the profile of Paolo Mantegazza, the article presents the original book published by Mantegazza in 1864 (second edition in 1865). The authors report extensive citations of Mantegazza's original book dealing with sleep hygiene. Mantegazza's indications, compared with Hauri's rules show important similarities. The authors support the view that the fatherhood of sleep hygiene should be acknowledged to Mantegazza and antedated to 1864. Hauri keeps the merit of giving more solid scientific roots to the concept of sleep hygiene and of inserting it in the frame of modern sleep medicine.

    Full Text Available Este artigo tem por objetivo analisar como a mente se torna social, à luz das idéias de Bruner e frente às idéias de Valsiner. Bruner entende a mente como criadora de significados e busca compreender a interação através da qual a mente constitui e é constituída pela cultura. Propõe uma psicologia interessada na ação e seu caráter situacional, assim como nas formas em que os seres humanos produzem significados nos contextos culturais. As pessoas, para Bruner, são resultado do processo de produção de significados, realizado com o auxílio dos sistemas simbólicos da cultura. O artigo aborda os temas centrais discutidos pelo autor para fundamentar tais pressupostos. Valsiner aparece como um estudioso contemporâneo e em evidência, cujas premissas reivindicam mudanças, principalmente nas pesquisas em Psicologia do Desenvolvimento, semelhantes àquelas apresentadas por Bruner há 50 anos. Estas discussões tornam-se relevantes nos "espaços da Psicologia", especialmente aqueles relacionados à pesquisa e à Educação.The aim of this article is to analyse how the mind becomes social regarding Bruner's ideas as well as Valsiner's. Bruner, who considers the mind as meanings creator, seeks at understanding the interaction through which the mind constitutes and is constituted by the environment. Bruner proposes a psychology which is interested in the action, its situational feature as well as the way which human beings produce meanings within cultural contexts. According to the author these people are results from the meanings production process, accomplished with the aid of the environmental symbolic systems. This article will approach the themes once discussed by the author so as to serve as a basis to such assumptions. Valsiner will appear as a contemporary scholar in activity, whose premises claim changes, particularly researches in Development Psychology which are similar to those presented by Bruner 50 years ago. Such discussions have become relevant in the "psychology rooms", mainly those related to research and education.

    An experimental study was conducted to assess the physical and biological impacts of muddy fine sand dredged material dumped on a medium sand site Machu offshore the Seine Estuary. Complementary trophic web modelling tools were applied to the Machu ecosystem to analyse the effects of dumping operations. Results show that, after the dumping operations, the biomass of fish increased while invertebrate biomass remained relatively stable through time. Nevertheless, the biomasses of benthic invertebrates, omnivores/scavengers and predators showed some increases, while non-selective deposit feeders and filter feeders decreased. At the ecosystem level, results show that the total ecosystem activity, the ascendency and the overall omnivorous character of the food-web structure increased after dumping operations, whereas recycling subsequently decreased. Finally, the fine and medium sand habitat offshore from the Seine estuary, which undergoes regular natural physical perturbations, shows a high resilience after a short dumping phase.

    With the fast development of service outsourcing, there is much obscure recognition of the concept of service outsourcing. Service outsourcing is not Service industry outsourcing, but service activities outsourcing. Service out- sourcing covers manufacturing industry, service industry, etc. rather than service industry only. Accordingly, service outsourcing motivation theory should be reinter- preted and moderately expanded with service outsourcing practices. As the guide of the expanded theory, on the basis of the service outsourcing market-driving factors and the elements of choosing service provider, we should build the com- petitive power evaluation system of the areas undertaking service outsourcing, and actively promote the work of CMMI qualification certification of our enter- prises.%服务外包快速发展的同时,存在诸多对服务外包概念的模糊认识。服务外包不是服务业的外包,而是服务活动的外包。服务外包涵盖制造业、服务业各领域,而不仅仅是服务业一家的事情。相应地,服务外包动因理论应随服.务外包发展实践得以重新诠释并适度扩展。以扩展理论为指导,以服务外包市场驱动因素和选择接包商要素为基础,建立服务外包承接地竞争力评价体系,并积极推进接包商CMMI资质认证工作。

  17. A "present" for the future: the unexpected value of rediscovery.

    Science.gov (United States)

    Zhang, Ting; Kim, Tami; Brooks, Alison Wood; Gino, Francesca; Norton, Michael I

    2014-10-01

    Although documenting everyday activities may seem trivial, four studies reveal that creating records of the present generates unexpected benefits by allowing future rediscoveries. In Study 1, we used a time-capsule paradigm to show that individuals underestimate the extent to which rediscovering experiences from the past will be curiosity provoking and interesting in the future. In Studies 2 and 3, we found that people are particularly likely to underestimate the pleasure of rediscovering ordinary, mundane experiences, as opposed to extraordinary experiences. Finally, Study 4 demonstrates that underestimating the pleasure of rediscovery leads to time-inconsistent choices: Individuals forgo opportunities to document the present but then prefer rediscovering those moments in the future to engaging in an alternative fun activity. Underestimating the value of rediscovery is linked to people's erroneous faith in their memory of everyday events. By documenting the present, people provide themselves with the opportunity to rediscover mundane moments that may otherwise have been forgotten.

    The first results of Einstein-Maxwell equations established by Raincih in 1925 are therefore called the Raincih conditions. Later the result was rediscovered by Misner and Wheeler in 1957 and made the basis of their geometrodynamics. The present survey will consider didactically the curvature of spacetime attributed to an electromagnetic field with conceptual and calculational details.

    By means of a small watercolor, painted by a musicologist, the existence of the highschool observatory of Chemnitz was rediscovered. The small observatory was build in 1893 by means of funds and a donation: after WW I it was also used for popular education. During Nazi times, the observatory fell into neglect, and the mechanical damage made it impossible to put it back into operation after WW II The building was torn down in 1964 and forgotten.

    1994-12-01

    The availability of low-cost high-performance computing hardware and software has transformed the manner by which astronomical concepts can be re-discovered and explored in a laboratory that accompanies an astronomy course for non-scientist students. We present a strategy for allowing each student to understand fundamental scientific principles by interactively confronting astronomical and physical phenomena, through direct observation and by computer simulation. Direct observation of physical phenomena, such as Hooke's Law, begins by using a computer and hardware interface as a data-collection and presentation tool. In this way, the student is encouraged to explore the physical conditions of the experiment and re-discover the fundamentals involved. The hardware frees the student from the tedium of manual data collection and presentation, and permits experimental design which utilizes data that would otherwise be too fleeting, too imprecise, or too voluminous. Computer simulation of astronomical phenomena allows the student to travel in time and space, freed from the vagaries of weather, to re-discover such phenomena as the daily and yearly cycles, the reason for the seasons, the saros, and Kepler's Laws. By integrating the knowledge gained by experimentation and simulation, the student can understand both the scientific concepts and the methods by which they are discovered and explored. We present the laboratory experiments (also available via anonymous FTP from ASTRO4.AST.VILL.EDU), and information concerning the hardware and software requirements. This work is supported by a grant from The Pew Charitable Trusts.

    Full text: The Antarctic Continent and its surrounding Southern Ocean are the least known regions of the world, mainly due to the most unfavorable climatic conditions, in which sampling for environmental studies are quite difficult to be carried out. Admiralty Bay on the King George Island (Antarctica) hosts three research stations, Arctowski, Ferraz and Macchu Picchu, which are operate by Poland, Brazil and Peru, respectively. Therefore, human activities in this region require the use of fossil fuel as an energy source, which is also considered the main source of pollutants in the area. This work investigated the natural and anthropogenic inputs of chemical elements in sediment samples collected close to Ferraz Station, during the 25{sup th} Brazilian Antarctica Expedition in the 2006/2007 austral summer. Total concentrations of As, Zn and Sc were determined in sediment profiles by using the Instrumental Neutron Activation Analysis (INAA). The analytical technique employed to determine the major elements such as Fe, Al, Ca, Mn and Ti was X-ray fluorescence (XRF) spectroscopy. For estimating the sedimentation rate, High Resolution Gamma Ray Spectrometry was applied to determine {sup 137}Cs, after 30 days, to achieve secular equilibrium. According to the enrichment factor and the geochronology analysis, the most relevant enrichment was observed for As in the sediment samples, suggesting the increasing of its content due to the Brazilian activities in the Admiralty Bay. Despite some evidences of anthropogenic contribution, the study indicated low level of environmental risk for this region. (author)

Further, students are encouraged to place these discoveries in an historical context, by discovering, for example, the night sky as seen by the survivors of the sinking Titanic, or Halley's comet as depicted on the Bayeux tapestry. We report on the continuing development of these laboratory experiments. Futher details and the text for the experiments are available at the following site: http://astro4.ast.vill.edu/ This work is supported by a grant from The Pew Charitable Trusts.

    2007-01-01

    This article is an experimental methodological reflection on the use of medical images as useful documents for constructing the history of medicine. A method is used that is based on guidelines or analysis topics that include different ways of viewing documents, from aesthetic, technical, social and political theories to historical and medical thinking. Some exercises are also included that enhance the proposal for the reader: rediscovering the worlds in society that harbor these medical photographical archives to obtain a new theoretical approach to the construction of the history of medical science.

    Greene, S K

    2001-08-01

    The reintroduction and development of safe motorized instruments, the increased availability of continuing education, and the understanding and implementation of appropriate procedures allow practitioners to provide better dental care. Veterinarians realize that sedation, analgesia, a full-mouth speculum, and proper instrumentation are necessary to provide these services. Continued instrument design, future research, and new treatment and prophylactic protocols should have a positive impact on the future of equine dental health. New and rediscovered procedures for equilibrating equine occlusion are allowing horses to masticate more efficiently, carry a bit more comfortably, and experience improved performance. The horse, the horse owner, and the veterinary profession all benefit from providing complete equine dental care.

    The therapeutic potential of arsenic derivatives has long been recognized and was recently rediscovered in modern literature. Early studies demonstrated impressive activity of this compound in patients with relapsed acute promyelocytic leukemia (APL). Over the last 2 decades, intravenous arsenic trioxide has been used successfully, both alone and in combination with other agents, for the treatment of APL and, with some success, of other myeloid neoplasms. Arsenic trioxide is currently part the standard of care for patients with APL. More recently, oral formulations of this compound have been developed and are entering clinical practice. In this review, the authors discuss the evolution of arsenic in the treatment of APL and other myeloid neoplasms.

    Much of the original historical data behind the greatest discoveries in neuroscience are now lost. However, a recently rediscovered box of histological slides belonging to Sir Charles Sherrington, a pioneer in spinal cord and motor control research, has survived at the University of Oxford since 1936. Sherrington coined the term 'synapse', developed the concept of inhibition in neuronal function, demonstrated the integration of sensory and motor actions of the nervous system, and examined the synaptic activity of single neurons and their integration into neuronal circuits. Here, we explore Sherrington's lifetime of discoveries, with reference to histological specimens from his box of slides.

On the one hand, China topping Japan [the world's previous second largest economy] in terms of GDP marks the rising of Chinas economic status, which is a milestone in the modern world economic history since Japan replaced the former Federal Republic of Germany as the world's second largest economy in 1968.

    TWO thousand years ago, a kingdom named Loulan suddenly occurred in major Chinese and Western historical documents. Then, just as abruptly, in the middle of the fifth century, it disappeared. When Western adventurers undertook large scale excavations in China’s Western Regions about a century ago, Loulan was rediscovered. Many relics were dispersed to other countries. Since then, dense ancient ruins and scrolls written in different scripts have been discovered within the domain of Loulan. The true history of Loulan, however, is still buried in the desert.

    We survey elementary results in Minkowski spaces (i.e. finite dimensional Banach spaces) that deserve to be collected together, and give simple proofs for some of them. We place special emphasis on planar results. Many of these results have often been rediscovered as lemmas to other results. In Part I we cover the following topics: The triangle inequality and consequences such as the monotonicity lemma, geometric characterizations of strict convexity, normality (Birkhoff orthogonality), conjugate diameters and Radon curves, equilateral triangles and the affine regular hexagon construction, equilateral sets, circles: intersection, circumscribed, characterizations, circumference and area, inscribed equilateral polygons.

    Institute of Scientific and Technical Information of China (English)

    2001-01-01

    Making use of the discriminant sequence for polynomials, WR algorithm, Wu's elimination and a partial cylindrical algebraic decomposition, we present here a practical algorithm for automated inequality discovering which can discover new inequalities automatically without requiring to put forward any conjectures beforehand. That is complete for an extensive class of inequality_type theorems. Also this algorithm is applied to the classification of the real physical solutions of geometric constraint problems. Many inequalities with various backgrounds have been discovered or rediscovered by our program, DISCOVERER, which implements the algorithm in Maple.

    Mentorship has been rediscovered in the professional nursing literature. It is viewed as an integral relationship to be fostered between members of a discipline for the purpose of developing future nurse leaders. Inherent in the relationship are desired qualities or attributes that are to be taught and practiced by professional nurse leaders for the purpose of developing innovative institutional partnerships between healthcare agencies and schools of nursing. In this column, a unique definition of mentorship will be explicated from the human becoming school of thought. Ethical implications of the concept will be explored.

    Full Text Available We apply the two-variable (/, 1/-expansion method to construct new exact traveling wave solutions with parameters of the nonlinear (1+1-dimensional KdV-mKdV equation. This method can be thought of as the generalization of the well-known (/-expansion method given recently by M. Wang et al. When the parameters are replaced by special values, the well-known solitary wave solutions of this equation are rediscovered from the traveling waves. It is shown that the proposed method provides a more general powerful mathematical tool for solving nonlinear evolution equations in mathematical physics.

    1993-01-01

    The complexity of our health care environment and organizations requires a management style that moves beyond control to empowerment. Even though this complexity minimizes our ability to control events, many organizations are still preoccupied with the illusion of control. This restrains the performance of our health care organizations. Some of the contributing factors supporting this illusion are bureaucracy, scientific methodology, individualism, and our confusion of management with leadership. The concept of "community" is discussed from an organizational perspective. It is suggested that we can improve the performance of our organizations by rediscovering the values of community.

    2005-06-01

    The multiple historical layers of Roger Chillingworth's character have been overlooked in criticism of The Scarlet Letter. By considering the possible influence of Robert Browning's dramatic poem Paracelsus (1835) on Hawthorne's romance (1850), as well as the ways in which overtones of both herbalism and clinical medicine complicate Chillingworth's character, one rediscovers Chillingworth as Hawthorne's audience likely experienced him: as a fictional palimpsest bearing multiple inscriptions of medical history that reveal an interplay between integrity and corruption. Thus, an interdisciplinary reading of The Scarlet Letter challenges the conventional critical assessment of Chillingworth as a satanic or Faustian figure.

The challenge is important at a time when the therapeutic alliance is simpler to establish, promotes the accompaniment of anxiety disorders in all their forms (separation anxiety, OCD), mood disorders or ADHD for example. We will touch the specificities of consultations proposed to a population more and more "sucked" by adolescence, and whose profile evolves singularly.

    The literature is replete with astronomical references. And much of that literature is poetry. Using this fact, not only can the teacher infuse a new appreciation of astronomy, but also, the student has the opportunity to rediscover history through astronomy. Poetry can be an effective icebreaker in the introduction of new topics in physics and astronomy, as well as a point of conclusion to a lecture. This presentation will give examples of these things from the ancient literature (sacred Hebraic texts), classical literature (Homer's Iliad and Odyssey), traditional poetry (Longfellow, Tennyson and Poe) and modern literature (Frost, Kooser, and others, including the contemporary work of this author).

    Full Text Available For over 20 years, I have tried to establish a relative date for petroglyphs in Fugoppe Cave, Japan. Unsuspected amidst debris accumulating from about 1300 years ago, the petroglyphs were rediscovered accidentally in 1950. From an analysis of petroglyphs on fallen rocks scattered randomly on the site floor, I argue that the artworks date from ca.1900 years ago. The cave itself, formed by wave action, saw its main occupation by pottery-making people from 1700–1500 years ago; although the petroglyphs on the rock walls predated their occupation, it seems unlikely that the occupants attached any meaning to them.

    The history of women's religious congregations is a history of addressing unmet needs. The founders and foundresses of our communities read the signs of their times and gathered women together to serve God and God's most vulneiable people. When the Second Vatican Council invited us to re-examine our founding charisms in light of the needs of our times, we rediscovered our own preferential option for those who are poor, often with a special care for women and children. While we continued to engage in traditional minis- tries serving the people of God without distinction, we expanded our outreach through social services, pastoral ministries and work for social justice and systemic change.

    Full Text Available In stimulus-parity synaesthesia, a range of stimuli—for example, letters, numbers, weekdays, months, and colours (the inducers—elicit an automatic feeling of oddness or evenness (the concurrent. This phenomenon was first described by Théodore Flournoy in 1893, and has only recently been “rediscovered.” Here, we describe an individual who experiences a comparable phenomenon, but uses the labels negative and positive rather than odd and even. Stimulus-parity synaesthesia may be broader than first supposed, and it is important that assessments are sensitive to this breadth.

    Full Text Available In this survey we present our recent results on analysis of gamma function and related functions. The results obtained are in the theory of asymptotic analysis, approximation of gamma and polygamma functions, or in the theory of completely monotonic functions. The motivation of this first part is the work of C. Mortici [Product Approximations via Asymptotic Integration Amer. Math. Monthly 117 (2010 434-441] where a simple strategy for constructing asymptotic series is presented. The classical asymptotic series associated to Stirling, Wallis, Glaisher-Kinkelin are rediscovered. In the second section we discuss some new inequalities related to Landau constants and we establish some asymptotic formulas.

    Full Text Available This essay proposes and rediscovers the passionate interrelation between nursing and biopedagogy. It makes the permanent presence of learning from life evident in nursing as an art from its historical roots. From the ontological femininity that gave it meaning, nursing represents itself as rhythmic and sequentially interwoven to biopedagogy, and both, as units, integrated to a whole which constitutes a quantum leap5 which in turn transforms complexity into simplicity and vice versa; therefore, creativity becomes complex. The sources that nurture and keep the intricacies of nursing and biopedagogy proposed here emerge from the powerful kotodama6 of Florence Nightingale, insigne modern nursing founder.

    Full Text Available An encounter even a confrontation, with Marxism and Neo-Marxism cannot leave Calvinism untouched. Calvinism’s critique of modern Western culture, especially since the Enlightenment, has not prevented leaders in South Africa committed to Calvinism to subscribe uncritically to power ideologies derived from Enlightenment philosophy. A crisis in the course of Calvinism in South Africa has become apparent. Neo-Marxism affords us with categories to analize this problem critically. Calvinism in South Africa should heed the lessons from this exercise in a critique of ideology, and rediscover its own and original humanism.

    Full Text Available Nocturia is a prevalent condition of waking to void during the night. The concept of nocturia has evolved from being a symptomatic aspect of disease associated with the prostate or bladder to a form of lower urinary tract disorder. However, recent advances in circadian biology and sleep science suggest that it might be important to consider nocturia as a form of circadian dysfunction. In the current review, nocturia is reexamined with an introduction to sleep disorders and recent findings in circadian biology in an attempt to highlight the importance of rediscovering nocturia as a problem of chronobiology.

    India is a vast country depicting wide social, cultural and sexual variations. Indian concept of sexuality has evolved over time and has been immensely influenced by various rulers and religions. Indian sexuality is manifested in our attire, behavior, recreation, literature, sculptures, scriptures, religion and sports. It has influenced the way we perceive our health, disease and device remedies for the same. In modern era, with rapid globalization the unique Indian sexuality is getting diffused. The time has come to rediscover ourselves in terms of sexuality to attain individual freedom and to reinvest our energy to social issues related to sexuality.

It is a geographical as well as a dreamscape of Adam where Eve is, but forbidden to Trespass. It is published by Phoenix, Orion Books Ltd 2010 with its first sentence as, “Muthavva knew her seventh child was special, had known from the very day of her birth, the day of the herons.” (p-1 It is an unusual story of a village girl raped by her friend, she eventually loses her childhood love, Machu and that grief shatters her life. Through her artistic sensibilities Mandanna depicts the inner sufferings of Devi, the protagonist. Keeping aside her marriage, Devi fights the trauma of rape and her lost love. She represents undaunted courage to establish herself in business, family and society. Devi voices her resentment to Devanna through the medium of her incessant hard labour and establishing herself as the ‘Coffee Queen’, fighting against all odds. Sarita Mandanna uplifts Devi from all adversities and makes her fight not to get lost in isolation and stagnation after the rape. In fact, she fights for her identity and emphasizes her presence with a bang. Tiger Hills explores the connections between fortitude and acceptance, the choices we make in the aftermath of coincidence and their far-reaching impact. Determined not to be victimized, Devi fights for her existence and happiness the best she can. She isn't always easy to like and makes some decisions that are far from right. As she forges a life for herself within the parameters decided for her, Devi hardens to such an extent that she becomes wedded to a version of happiness rooted in memory to ever become real.

    Full Text Available Thirty-three examples of oral sayings, mainly from the Golok area, used in conflict mediation are presented and discussed in terms of their usage by mediators and how they reflect Tibetan values and life. ''You have to go to Golok to hear real tamxhwe." Conflict resolution is a topic most Amdo Tibetans will readily discuss and the oratorical skills of the zowa (gzu ba 'mediators' are always emphasized. It was in Golok that they were said to be particularly impressive. ''They make displays of oratory during the early stages of the mediation process,'' explained one informant, a respected mediator from Machu (Rma chu. ''They use proverbs and riddles that are difficult to understand. It is like jousting with words, a display of skill.'' He was referring to the representatives of individual parties, but the same skills are even more important for mediators. The more serious and entrenched the conflict—two Amdo tribes may fight for generations over valuable grassland—the more important it is to secure a high-status mediator, often a lama or local leader with a reputation for oratory. The mediators' task is to persuade reluctant parties to compromise and accept compensation in lieu of taking revenge for an injury or killing; this can require a lengthy and elaborate process extending over several days. ''In Golok,'' my informant continued, ''they use tamxhwe; those who can make good speeches and employ it well enjoy high reputations.'' The tamxhwe, it appeared, were like proverbs or riddles and in one or two cases an informant was able to repeat one of them to me, but I was repeatedly told that I had to go to Golok to learn more. The oratorical skills of the Golok mediators obviously had a considerable reputation throughout Amdo, and in the summer of 2004 I went to this large area in southern Qinghai Province to investigate. ...

  11. The Role of Lighthouses in the Construction of Coastal Identities

    Directory of Open Access Journals (Sweden)

    Elisa Magnani

    2017-01-01

    Full Text Available Mysterious and fascinating figures – a light that brightens the land where it meets the sea – lighthouses have always played a vital role not only in drawing the line of the coast, but also in creating the social and cultural identity of those people who live at the edge of the land, in the finis terrae. Lighthouses have known an architectonic and maritime history of their own, but most of them were abandoned after the decline of the maritime economy and the introduction of new technologies. Nowadays they are being rediscovered, both as part of a process of territorial re-appropriation enacted by the local communities, aiming at transforming them in modern houses or recovering their traditional use, and as part of tourist development policies, making of them new tourist accommodation for people wishing to live new types of cultural experiences or interested in re-discovering the history and memory of a territory. The article analyses the role of lighthouses in the creation of territorial identities and in the tourist exploitation of the European coastal landscapes in areas with a strong maritime identity, inexorably connected with these coastal “giants”, symbols of both defense and openness towards otherness.

    2008-05-01

    Our aim was to evaluate the potential of existing herbarium collections in reconstructing the past population history of the rediscovered clone of the regionally extinct Blechnum spicant by comparing it with herbarium material from previous sites of occurrences in Finland and elsewhere in northern Europe, as well as to reveal the genetic and geographic relationship among the samples. We detected a total of nine polymorphic sites within the three sequenced regions, two SCAR markers developed now for B. spicant and the chloroplast trnL-trnF spacer, totalling 763 bp. Despite low variability, the phylogeographic analysis revealed the presence of some geographic pattern among the samples, of which all except one represented herbarium samples of up to 100 years of age. The rediscovered clone of B. spicant proved to represent the prevalent genotype occurring in northern Europe. The studied sequences were neutral in terms of evolution. It is apparent that existing herbarium collections are useful resources for a range of evolutionary and population studies.

  13. Mining workflow processes from distributed workflow enactment event logs

    2012-12-01

    Full Text Available Workflow management systems help to execute, monitor and manage work process flow and execution. These systems, as they are executing, keep a record of who does what and when (e.g. log of events. The activity of using computer software to examine these records, and deriving various structural data results is called workflow mining. The workflow mining activity, in general, needs to encompass behavioral (process/control-flow, social, informational (data-flow, and organizational perspectives; as well as other perspectives, because workflow systems are "people systems" that must be designed, deployed, and understood within their social and organizational contexts. This paper particularly focuses on mining the behavioral aspect of workflows from XML-based workflow enactment event logs, which are vertically (semantic-driven distribution or horizontally (syntactic-driven distribution distributed over the networked workflow enactment components. That is, this paper proposes distributed workflow mining approaches that are able to rediscover ICN-based structured workflow process models through incrementally amalgamating a series of vertically or horizontally fragmented temporal workcases. And each of the approaches consists of a temporal fragment discovery algorithm, which is able to discover a set of temporal fragment models from the fragmented workflow enactment event logs, and a workflow process mining algorithm which rediscovers a structured workflow process model from the discovered temporal fragment models. Where, the temporal fragment model represents the concrete model of the XML-based distributed workflow fragment events log.

  14. The quickly switching routing algorithm based on multi-path in mobile Ad Hoc networks

    Institute of Scientific and Technical Information of China (English)

    2006-01-01

    This paper proposes a new on-demand multi-alternate-path algorithm, called quickly switching routing algorithm(QSRA). It switches failure routing to an alternate path as quickly as the network can. Like a nervure shape, algorithm QSRA shapes disjoint-alternate-path structure, but is not limited to. It also contains another structure that every primary node has several links to alternate paths. This structure has two advantages, the first one is that primary nodes can select one alternate path immediately when primary routing is failure without going back to source node to re-discover a new routing or choose an alternate path; the second is that it guarantees primary nodes can select another alternate path as quickly as possible once one of alternate paths fails. Strongpoint of algorithm QSRA is reducing frequency of routing re-discovering. Besides, the structure occupies fewer resources than other routing algorithms due to its distributed structure. Simulation shows that QSRA has higher packets received ratio and lower control packet overhead and lower end-to-end delay.

    2014-02-01

    Full Text Available Plesiochelyidae are a major component of Late Jurassic shallow marine environments throughout Europe. However, the taxonomy of plesiochelyid turtles is rather confused. Over the years, many taxa have been synonymized with Plesiochelys etalloni, one of the first described species. However, the holotype of P. etalloni (and only specimen known from Lect, the type locality was lost for more than 150 years. This specimen has been recently rediscovered in the collections of the Musée d’archéologie du Jura in Lons-le-Saunier, France. For the first time since its original description in 1857, the holotype of P. etalloni is redescribed and compared to relevant material. The taxonomic status of this taxon is revised accordingly. Based on the morphology of the newly rediscovered holotype and on a reassessment of specimens from Solothurn (Switzerland, the species P. solodurensis, P. sanctaeverenae and P. langii are synonymized with P. etalloni. Known skull-shell associations for P. etalloni are re-evaluated in light of the new morphological information available since the rediscovery of this holotype specimen. Finally, we confirm that Plesiochelys is represented by a single species in the Late Jurassic of the Jura Mountains.

  16. Discovery of multi-ring basins - Gestalt perception in planetary science

    Hartmann, W. K.

    1981-01-01

    Early selenographers resolved individual structural components of multi-ring basin systems but missed the underlying large-scale multi-ring basin patterns. The recognition of multi-ring basins as a general class of planetary features can be divided into five steps. Gilbert (1893) took a first step in recognizing radial 'sculpture' around the Imbrium basin system. Several writers through the 1940's rediscovered the radial sculpture and extended this concept by describing concentric rings around several circular maria. Some reminiscences are given about the fourth step - discovery of the Orientale basin and other basin systems by rectified lunar photography at the University of Arizona in 1961-62. Multi-ring basins remained a lunar phenomenon until the fifth step - discovery of similar systems of features on other planets, such as Mars (1972), Mercury (1974), and possibly Callisto and Ganymede (1979). This sequence is an example of gestalt recognition whose implications for scientific research are discussed.

    2017-09-01

    Municipal organic waste (MOW) is a promising feedstock for biogas plants and separate collection will increase available quantities. To close nutrient circles digestates shall be redistributed to arable land. However, less is known about digestate properties and how they are influenced during digestion. Therefore, changes in nutrient and heavy metal concentration in the solid digestate were investigated during anaerobic treatment of MOW in a two-stage laboratory biogas plant. Results show that the solid digestate is exposed to element accumulation, except for N, P and Mg. The loss of initial N, P and Mg load accounts up to 45%, which must be redistributed elsewhere in the digester system. K load of feedstock was completely rediscovered in the solid digestate. Heavy metal concentration in the digestate increases by factor 1.6 at average. The results emphasize that element retention in the digester system has a decisive impact on nutrient content of digestates. Copyright © 2017 Elsevier Ltd. All rights reserved.

    2017-02-01

    During the Middle Ages and the Renaissance, intellectuals often included clinical cases and medical descriptions in their literary works. These authors appeared to be more interested in internal and infectious diseases rather than in musculoskeletal disorders and orthopaedics. François Rabelais (1490-1553) was one of the most renowned humanists and philologists of the sixteenth century. He was also a physician with an interest in translating ancient texts of medical authors. Rabelais rediscovered a device for treating femoral fracture originally described by the Roman physician Galen and named as glossocomion. Since the original apparatus had some imperfections, Rabelais redesigned and modified it. This new, improved version became a model for new devices for treating femoral fracture, as also reported by the great French surgeon Ambroise Paré. For this contribution, Rabelais deserves major consideration in the history of orthopaedics and traumatology.

    2012-01-01

    Once feared to be extinct, black-footed ferrets (Mustela nigripes) were rediscovered near Meeteetse, Wyoming, in 1981, resulting in renewed conservation and research efforts for this highly endangered species. A need for information directly useful to recovery has motivated much monitoring of ferrets since that time, but field activities have enabled collection of data relevant to broader biological themes. This special feature is placed in a context of similar books and proceedings devoted to ferret biology and conservation. Articles include general observations on ferrets, modeling of potential impacts of ferrets on prairie dogs (Cynomys spp.), discussions on relationships of ferrets to prairie dog habitats at several spatial scales (from individual burrows to patches of burrow systems) and a general treatise on the status of black-footed ferret recovery.

  20. [From the willow to aspirin].

    Lafont, Olivier

    2007-07-01

    At the beginning was the willow bark, which was considered as a medicine by Hippocrates, Dioscorides and Plinus. During the XVIIIth century, the Reverend Edward Stone re-discovered the willow for the cure of agues. In 1829, the french pharmacist Pierre Joseph Leroux isolated salicin. Raffaelle Piria was the first to synthesize salicylic acid from salicin (salicoside). Hermann Kolbe prepared salicylic acid from sodium phenate and carbon dioxide. And then acetylsalicylic acid was first prepared by Charles Gerhardt in 1853, but he did not succeed in identifying its structure. Felix Hoffmann, Arthur Eichengrun and Heinrich Dresen from Bayer Laboratories were at the origin of the use of Aspirin as a medicine. In 1971, John Vane showed that aspirin-like drugs inhibited prostaglandine synthesis.

    Full Text Available Within today’s Italian experience, we can see how as a society, we are adapting to a new world, in the fields of work, art and technical production, mainly following a virtual road, often fake and scenographic, often very far from the real contents. This approach is realized through the use of new words, and mainly through the use of old terms, intended for new stereotypes, in order to create a new world, more attractive and beautiful, but parallel, and at end of the day, nothing but useless. The paper focusses on these words - also trough the help of the enclosed drawings, just generally related to the topic, and takes into account their use, as they are really pervasive, but lacking of a real significance. Our aim is also that of asking to artists and technicians to rediscover a better connection between brain and hand, in order to give the development of new ideas through craftsmanship, a chance.

    2015-01-01

    In this paper we present three newly rediscovered documents from the Royal Society archives that, together with the four described in our previous publications, constitute a set on a cognate theme. The documents were written by, or addressed to, members of the early Royal Society, and their subject is several magisterial formulae, including J. B. van Helmont's alkahest and Ludus. In addition to the interest in those formulae as medicines for various grave illnesses, our analysis showed that some seventeenth-century scholars sought to explain operations of the animal body by invoking similar but natural substances, while attempting to assimilate the latest anatomical discoveries into a novel framework. The complete set of documents sheds some new light on the interests of seventeenth-century networks of scholars concerned with experimenta. PMID:26665488

    1995-12-10

    The article is meant to give new insight into the history of literature: During the last ten years of his life, Welhaven produced neither poetry nor prose and lived withdrawn in his own house, mainly because he had Parkinson's disease. He understood himself, as his doctors did--and his biographers--that he suffered from a brain disease. However, nobody was able to make a Parkinson diagnosis in Norway in the 1860s. This was perhaps possible for a handful of French neurologists, who at this time "rediscovered" James Parkinson's "An Essay on the shaking palsy" from 1817--and named the disease Maladie de Parkinson, or Parkinson's disease. When a neurologist today reads Welhaven's own observations or those of his contemporaries, and his biographies, he has little doubt about the diagnosis.

    Full Text Available Searching for information on the Internet is not only an activity newly rediscovered, but also a strategic tool to achieve a wide variety of information. Indeed, it’s extremely important to know how to find the information quickly and efficiently. Unfortunately, the Web is so huge and so little structured, that gathering precise, fair and useful information becomes an expensive task. In order to define an information retrieval tool (meta search engine that brings together multiple sources of information search, interest must be credited to the merger phase of search engines results. On the other hand, information search systems tend primarily to model the user with a profile and then to integrate it into the information access chain, to better meet its specific needs. This paper presents a custom fusion method based on Borda method and values retrieved from the user profile. We evaluated our approach on multiple domains and we present some experimental results.

    2011-03-01

    The quasigeostrophic two-layer model is of superior interest in dynamic meteorology since it is one of the easiest ways to study baroclinic processes in geophysical fluid dynamics. The complete set of point symmetries of the two-layer equations is determined. An optimal set of one- and two-dimensional inequivalent subalgebras of the maximal Lie invariance algebra is constructed. On the basis of these subalgebras, we exhaustively carry out group-invariant reduction and compute various classes of exact solutions. Wherever possible, reference to the physical meaning of the exact solutions is given. In particular, the well-known baroclinic Rossby wave solutions in the two-layer model are rediscovered.

We report on a strategy, begun in 1992, for allowing each student to understand fundamental scientific principles by interactively confronting astronomical and physical phenomena, through direct observation and by computer simulation. These experiments have evolved as :a) the quality and speed of the hardware has greatly increasedb) the corresponding hardware costs have decreasedc) the students have become computer and Internet literated) the importance of computationally and scientifically literate arts graduates in the workplace has increased.We present the current suite of laboratory experiments, and describe the nature, procedures, and goals in this two-semester laboratory for liberal arts majors at the Astro 101 university level.

  9. Multiple Scattering Methods in Casimir Calculations

    Milton, Kimball A

    2007-01-01

    Multiple scattering formulations have been recently rediscovered as a method of studying the quantum vacuum or Casimir interactions between distinct bodies. The methods are hardly new, but increased computing power and advances in understanding allow us to extract information efficiently. Here we review the method in the simple context of $\\delta$-function potentials, so-called semitransparent bodies. (In the limit of strong coupling, a semitransparent boundary becomes a Dirichlet one.) After applying the method to rederive the Casimir force between two semitransparent plates and the Casimir self-stress on a semitransparent sphere, we obtain expressions for the Casimir energies between disjoint parallel semitransparent cylinders and between disjoint semitransparent spheres. Simplifications occur for weak and strong coupling. In particular, after performing a power series expansion in the ratio of the radii of the objects to the separation between them, we are able to sum the weak-coupling expansions exactly t...

  10. Learning Effective Treatment Pathways for Type-2 Diabetes from a clinical data warehouse.

    2016-01-01

    Treatment guidelines for management of type-2 diabetes mellitus (T2DM) are controversial because existing evidence from randomized clinical trials do not address many important clinical questions. Data from Electronic Medical Records (EMRs) has been used to profile first line therapy choices, but this work did not elucidate the factors underlying deviations from current treatment guidelines and the relative efficacy of different treatment options. We have used data from the Stanford Hospital to attempt to address these issues. Clinical features associated with the initial choice of treatment were effectively re-discovered using a machine learning approach. In addition, the efficacies of first and second line treatments were evaluated using Cox proportional hazard models for control of Hemoglobin A1c. Factors such as acute kidney disorder and liver disorder were predictive of first line therapy choices. Sitagliptin was the most effective second-line therapy, and as effective as metformin as a first line therapy.

  11. Metrics of Risk Associated with Defects Rediscovery

    CERN Document Server

    Miranskyy, Andriy V; Reesor, Mark

    2011-01-01

    Software defects rediscovered by a large number of customers affect various stakeholders and may: 1) hint at gaps in a software manufacturer's Quality Assurance (QA) processes, 2) lead to an over-load of a software manufacturer's support and maintenance teams, and 3) consume customers' resources, leading to a loss of reputation and a decrease in sales. Quantifying risk associated with the rediscovery of defects can help all of these stake-holders. In this chapter we present a set of metrics needed to quantify the risks. The metrics are designed to help: 1) the QA team to assess their processes; 2) the support and maintenance teams to allocate their resources; and 3) the customers to assess the risk associated with using the software product. The paper includes a validation case study which applies the risk metrics to industrial data. To calculate the metrics we use mathematical instruments like the heavy-tailed Kappa distribution and the G/M/k queuing model.

  13. Gombrich on image and time

    Directory of Open Access Journals (Sweden)

    Kristóf Nyíri

    2009-12-01

    Full Text Available There is a very close, indeed intrinsic, connection between the notions of image and time. Images are incomplete unless they are moving ones – unless, that is, they happen in time. On the other hand, time cannot be conceptualized except by metaphors, and so ultimately by images, of movement in space. That only the moving image is a full-fledged one is a fact that was fully recognized and articulated by Ernst Gombrich. Also, Gombrich entertained, and argued for, a rich and well-balanced view of the relationships between pictorial and verbal representation. An antidote to the unholy influence of Goodman, Gombrich deserves to be rediscovered as the figure whose work is ideally suited to providing a founding paradigm for a truly successful philosophy of images.

  14. A historical overview of bacteriophage therapy as an alternative to antibiotics for the treatment of bacterial pathogens.

    Wittebole, Xavier; De Roock, Sophie; Opal, Steven M

    2014-01-01

    The seemingly inexorable spread of antibiotic resistance genes among microbial pathogens now threatens the long-term viability of our current antimicrobial therapy to treat severe bacterial infections such as sepsis. Antibiotic resistance is reaching a crisis situation in some bacterial pathogens where few therapeutic alternatives remain and pan-resistant strains are becoming more prevalent. Non-antibiotic therapies to treat bacterial infections are now under serious consideration and one possible option is the therapeutic use of specific phage particles that target bacterial pathogens. Bacteriophage therapy has essentially been re-discovered by modern medicine after widespread use of phage therapy in the pre-antibiotic era lost favor, at least in Western countries, after the introduction of antibiotics. We review the current therapeutic rationale and clinical experience with phage therapy as a treatment for invasive bacterial infection as novel alternative to antimicrobial chemotherapy.

    2013-10-01

    Full Text Available During the study of rotifers collected in Eastern DR Congo, we rediscovered specimens that correspond to Monostyla dorsicornuta Van Oye, 1926. This species, which we redescribe, had not been seen since it’s summary description, and lacked type material. Our analysis reveals that the animal belongs to Trichotriidae rather than to Lecane (presently considered to include Monostyla or Lecanidae, but is nevertheless characterised by a foot structure that is remarkably convergent to that of Lecanidae, and different from all other genera of Trichotriidae.We conclude that the species and the closely related South American Macrochaetus kostei (José de Paggi, Branco & Kozlowsky-Suzuki, 2000 belong to a new genus of Trichotriidae; the two offer a rare example of African-South American vicariance in rotifers.We further provide emended diagnoses of the remaining genera of Trichotriidae, to conform these to the new information and to address some inconsistencies in these.

    Ramzi N. Nasser

    2007-01-01

    Full Text Available This paper discusses factors that are contributing to the rise of what we refer to as an ethos of “academic apartheid” in Arab institutions of higher education. The paper examines the failure of these institutions to overcome their alienation from indigenous epistemology, to emancipate the education they provide from its colonial past, and to move towards the modern information age. The difficult position of Arab academics striving to rediscover, reintegrate and reorganize an epistemological framework to serve the indigenous world is also discussed. Current institutional approaches have deleterious effects on the performance of Arab academics, including arresting the process of transition to development. The paper concludes that Arab academics have a range of choices in determining how to establish a course of corrective action.

    2012-01-01

    Starting from Zermelo’s classical formal treatment of chess, we trace through history the analysis of two-player win/lose/draw games with perfect information and potentially infinite play. Such chess-like games have appeared in many different research communities, and methods for solving them......, such as retrograde analysis, have been rediscovered independently. We then revisit Washburn’s deterministic graphical games (DGGs), a natural generalization of chess-like games to arbitrary zero-sum payoffs. We study the complexity of solving DGGs and obtain an almost-linear time comparison-based algorithm...... for finding optimal strategies in such games. The existence of a linear time comparison-based algorithm remains an open problem....

    Octavio Paz

    2014-03-01

    Full Text Available In 1973, when Octavio Paz writes The use and contemplation, the Western world had long known and assimilated the effects of the culture of technology. Indeed, one could already note signals of contrast: the technique, which had fully accomplished its life's course, was creating its own antidotes . The transnational, serial, anonymous, aseptic nature of the industrial object destined for the dump was counterbalanced by the rehabilitation of those values of which the craft object has always been dispenser: the reference to the body and to a kind of "erotic" aesthetics , the socializing and sharing, the local specialty, a peculiar type of transmission of memory and knowledge. Paz rediscovers in the handmade article the ability to reactivate those dimensions  of existence  neutralized by industry (oriented to the use and transcended by the religion of the modern art (consecrated by the function of contemplation.

    Full Text Available This article analyzes the history of the environmental principal of sustainability in agrarian and industrial cultures. Its example is Central Europe between the Middle Ages and the 21st century. After the great deforestation of the 12th century, and reaching the limits of the region’s carrying capacity in the 15th century, the European seignorial-communal culture developed a model of sustainability appropriate for a socio-metabolic system based on solar energy, elements of decentralization in local entities, recognition of the upper-limits of the local ecosystem, systemic control of environmental consumption, and the optimization of the use of scarce resources. This system operated until the double Enlightenment-Industrial Revolution at the turn of the 19th century. The socio-metabolic system of the 19th century tried to exist without sustainability, but this concept was rediscovered in the 1990s.

  3. Choreographic solution to the general-relativistic three-body problem.

    2007-05-18

    We reexamine the three-body problem in the framework of general relativity. The Newtonian N-body problem admits choreographic solutions, where a solution is called choreographic if every massive particle moves periodically in a single closed orbit. One is a stable figure-eight orbit for a three-body system, which was found first by Moore (1993) and rediscovered with its existence proof by Chenciner and Montgomery (2000). In general relativity, however, the periastron shift prohibits a binary system from orbiting in a single closed curve. Therefore, it is unclear whether general-relativistic effects admit choreography such as the figure eight. We examine general-relativistic corrections to initial conditions so that an orbit for a three-body system can be choreographic and a figure eight. This illustration suggests that the general-relativistic N-body problem also may admit a certain class of choreographic solutions.

These stopping rules are based on survey data for counts of co-occurring species that are encountered in the search for a target species. We illustrate both these methods with a case study of the Ivory-billed Woodpecker......Assessing species survival status is an essential component of conservation programs. We devised a new statistical method for estimating the probability of species persistence from the temporal sequence of collection dates of museum specimens. To complement this approach, we developed quantitative...... (Campephilus principalis), long assumed to have become extinct in the United States in the 1950s, but reportedly rediscovered in 2004.

    Full Text Available Cereals represent the most important group of crops in the structure of plant production from the economic, agronomic and consumer point of view. Spelt wheat (Triticum spelta L. is an ancient bread cereal related to wheat (Triticum aestivum L. that has been cultivated for hundreds of years, and that is now being rediscovered in Europe and North America. Spelt is generating increasing interest due to its agronomic, nutritional and medical characteristics. Despite of these spelt bread benefits, spelt is wheat that contains gluten proteins and is capable of provoking wheat allergy and gluten enteropathy. This review describes nutritional composition (proteins, aminoacids, starch, sugars, fiber, lipids, fatty acids, sterol, vitamins, ash and mineral compounds of spelt wheat and potential using of this cereal for baking application (flour, bread, breakfast cereals, pasta, crackers, nutrition bars, biscuits and some regional specialities.

    2016-09-01

    Full Text Available Sourdough fermentation, a traditional biotechnology for making leavened baked goods, was almost completely replaced by the use of baker’s yeast and chemical leavening agents in the last century. Recently, it has been rediscovered by the scientific community, consumers, and producers, thanks to several effects on organoleptic, technological, nutritional, and functional features of cereal-based products. Acidification, proteolysis, and activation of endogenous enzymes cause several changes during sourdough fermentation, carried out by lactic acid bacteria and yeasts, which positively affect the overall quality of the baked goods. In particular, the hydrolysis of native proteins of the cereal flours may improve the functional features of baked goods. The wheat flour processed with fungal proteases and selected lactic acid bacteria was demonstrated to be safe for coeliac patients. This review article focuses on the biotechnologies that use selected sourdough lactic acid bacteria to potentially counteract the adverse reactions to gluten, and the risk of gluten contamination.

    Full Text Available The emergence of the nation states was one of the fruits of Romanticism,and each reborn country needed to rediscover its identity: in Ireland, identitywas very much tied to the landscape and what remained of the Irish language,place-names playing a special role in the evocation of national desires.A study of these key texts of Yeats’ shows how his dedication to the life ofthe mind mirrored the loss of contact with the natural world. This is true of itslandscapes and its mythological figures. I hope to show that in an early poem“The Song of Wandering Aengus” that in developing an antithetical self, Yeatswas at significant times not only opposed to Nature intellectually andspiritually, but also emotionally. The privileging of the life of the mind over theanimal self has played in his own life and in his influence what may have been acostly division.

    In preparing to develop a cost-benefit methodology that could be applied to potential projects abroad involving new coal-fired power plants that make use of US clean coal technologies, the author reviewed a wide variety of reference sources. These are listed in this publication. Before this review, the author had conducted a number of literature searches that identified source material in the newly rediscovered field of environmental externalities and related topics that might also be of value to other energy and environmental researchers. Those sources that appeared to be appropriate but that the author was unable to review are also listed in this document. Thus, this document serves as a comprehensive compendium of source material on these subjects, arranged alphabetically within categories.

    2015-01-01

    Full Text Available The interest in digital libraries began in the early nineties of the last century, particularly in the United States. At first the argument involved a few computer scientists and some librarian. However, after the first terminological uncertainties ("electronic" library, "virtual" library, etc., digital libraries have become an object of interdisciplinary study and today constitute a research field of LIS. Over the years there has been an evolution of topics and approaches. The earlier prevailing interest was in the management and technological aspects of digital libraries and then emerged the need to rediscover the role of digital libraries in society. This paper focuses in particular on the most recent international debate on the social value of the digital library.

    Darrigol, Olivier

    2017-07-01

    Joseph Boussinesq was the most prolific of all French contributors to nineteenth-century fluid mechanics. His scientific production included a novel theory of solitary waves, the KdV equation for finite deformations of the water surface in an open channel, a systematic study of open channel and pipe flow based on the concept of effective viscosity, pioneering derivations of boundary layers and entrance effects, new exact solutions of the Navier-Stokes equation under geometrically simple boundary conditions, and the 'Boussinesq approximation' for heat convection in a moving fluid under gravity. Although his extraordinary skills were quickly recognized and rewarded, other experts in the field were often unaware even of his most important results and they ended up rediscovering some of them. Boussinesq's unusual background and the resulting peculiarities of his style explain this problematic diffusion. They also account for the richness of his legacy.

    Demographic change is a drama in slow motion, and the America of the early 21st century is undergoing two such dramas at the same time. Our population is en route to becoming majority non-White at the same time a record share of us are going gray. Either of these trends would be the dominant demographic story of this era. The fact that they are occurring simultaneously has created significant generation gaps. The paradox of these sorts of dramas is that even though they are happening all over, they can sometimes be hard to see. As Millennials assert themselves in the economy and the electorate, let's hope they press their elected leaders on these issues. And as Boomers cross over into their golden years, let's hope they do their share as well. If we want the American experiment to thrive at a time of sweeping demographic change, we must all rediscover our roots as a nation of planters

    2016-10-01

    Infection of mice with Citrobacter rodentium is a robust model to study bacterial pathogenesis, mucosal immunology, the health benefits of probiotics and the role of the microbiota during infection. C. rodentium was first isolated by Barthold from an outbreak of mouse diarrhea in Yale University in 1972 and was 'rediscovered' by Falkow and Schauer in 1993. Since then the use of the model has proliferated, and it is now the gold standard for studying virulence of the closely related human pathogens enteropathogenic and enterohemorrhagic Escherichia coli (EPEC and EHEC, respectively). Here we provide a detailed protocol for various applications of the model, including bacterial growth, site-directed mutagenesis, mouse inoculation (from cultured cells and after cohabitation), monitoring of bacterial colonization, tissue extraction and analysis, immune responses, probiotic treatment and microbiota analysis. The main protocol, from mouse infection to clearance and analysis of tissues and host responses, takes ∼5 weeks to complete.

    In both myth and Genesis (by God) the creation of the world begins with the separation of water, sky/air and ground; later appear the life and the man and from Olympic divinities (or God) derive health and disease and remedies. When Milesian philosophers distinguished between nature (to be observed) and speculation, a parallel revision has been made in the medicine, from theurgical to rational one. Thus, Hippocratic medicine pointed attention on air waters and places as natural environmental elements, to be observed, as method to understand the probable diseases of a city, also with a role of political institutions, says the Hippocratic treatise De aëre. Centuries later, only in the 19th century has been rediscovered the importance of environment in the health's policy, a concept full developed in the last time (i.e. health and pollution, health and quality of life).

    In 2012 a manuscript was rediscovered in the Biblioteca dell'Archiginnasio of Bologna, titled Libro degli infermi dell'Arciconfraternita di S. Maria della Morte. It is the record of incoming patients of one for the main hospitals of the city, devoted exclusively to the sick poor and not just to the poor, called Santa Maria della Morte, compiled by a young student assistant (astante) for the period 1558-1564. I publish here a transcription of a portion of this Libro pertaining to the year 1560. My introduction situates the manuscript within the context of the history of early modern Italian hospitals, describes the organization of the hospital of Santa Maria della Morte based on archival sources of the period, and finally highlights the connections between surgical and anatomical education and the internal organization of the hospital.

    collected single isolates, and only few have included cross-sectional analyses of entire P. aeruginosa populations in sputum samples. To date only few studies have used the approach of metagenomic analysis for the purpose of investigating P. aeruginosa populations in CF airways. We analysed five metagenomes...... together with longitudinally collected single isolates from four recently chronically infected CF patients. With this approach we were able to link the clone type and the majority of SNP profiles of the single isolates to that of the metagenome(s) for each individual patient. Based on our analysis we find...... that when having access to comprehensive collections of longitudinal single isolates it is possible to rediscover the genotypes of the single isolates in the metagenomic samples. This suggests that information gained from genome sequencing of comprehensive collections of single isolates is satisfactory...

  19. DaVinci's Mona Lisa entering the next dimension.

    Carbon, Claus-Christian; Hesslinger, Vera M

    2013-01-01

    For several of Leonardo da Vinci's paintings, such as The Virgin and Child with St Anne or the Mona Lisa, there exist copies produced by his own studio. In case of the Mona Lisa, a quite exceptional, rediscovered studio copy was presented to the public in 2012 by the Prado Museum in Madrid. Not only does it mirror its famous counterpart superficially; it also features the very same corrections to the lower layers, which indicates that da Vinci and the 'copyist' must have elaborated their panels simultaneously. On the basis of subjective (thirty-two participants estimated painter-model constellations) as well as objective data (analysis of trajectories between landmarks of both paintings), we revealed that both versions differ slightly in perspective. We reconstructed the original studio setting and found evidence that the disparity between both paintings mimics human binocular disparity. This points to the possibility that the two Giocondas together might represent the first stereoscopic image in world history.

    We present the results of the very first search for faint Milky Way satellites in the Gaia data. Using stellar positions only, we are able to re-discover objects detected in much deeper data as recently as the last couple of years. While we do not identify new prominent ultrafaint dwarf galaxies, we report the discovery of two new star clusters, Gaia 1 and Gaia 2. Gaia 1 is particularly curious, as it is a massive (2.2 × 104 M⊙), large (∼9 pc) and nearby (4.6 kpc) cluster, situated 10 arcmin away from the brightest star on the sky, Sirius! Even though this satellite is detected at significance in excess of 10, it was missed by previous sky surveys. We conclude that Gaia possesses powerful and unique capabilities for satellite detection, thanks to its unrivalled angular resolution and highly efficient object classification.

    The tardigrade class Mesotardigrada was erected on the basis of the description of Thermozodium esakii by Gilbert Rahm in 1937. In some characteristics, T. esakii is intermediate between members of the classes Eutardigrada and Heterotardigrada. The class Mesotardigrada is known only from Rahm's published drawings of T. esakii; no voucher specimens are known, and subsequent attempts to collect it at the locus typicus have been unsuccessful. Among the possible explanations for this situation are that Rahm may have collected specimens of a more typical tardigrade, but misinterpreted what he saw. Alternatively, changes in habitat in the area may have led to the tardigrade's extirpation. Perhaps T. esakii is a rare species, such that recent sampling efforts have been insufficient to rediscover it. Finally, Rahm's 1937 description may be an attempt at deception. Until physical evidence of T. esakii is found, the species, and by extension the class Mesotardigrada, should be considered nomen dubium.

    2013-03-01

    Let {f (z,bar z)} be a positive bi-homogeneous hermitian form on {mathbb{C}^n}, of degree m. A theorem proved by Quillen and rediscovered by Catlin and D'Angelo states that for N large enough, {<{z,bar z}rangle^Nf(z,bar z)} can be written as the sum of squares of homogeneous polynomials of degree m + N. We show this works for N ≥ C f (( n + m) log n)3 where C f has a natural expression in terms of coefficients of f, inversely proportional to the minimum of f on the sphere. The proof uses a semiclassical point of view on which 1/ N plays a role of the small parameter h.

  3. A taxonomic mystery for more than 150 years: Identity, systematic position and Malagasy origin of the snake Elapotinus picteti Jan, 1862, and synonymy of Exallodontophis Cadle, 1999 (Serpentes: Lamprophiidae).

    2014-08-14

    Elapotinus picteti Jan, 1862 is an enigmatic snake taxon that has been described without locality data. Genus and species, both based on the unique holotype, were considered to belong to the venomous African Aparallactinae for more than a century, but although this taxon was never rediscovered it was accepted as a valid species until present. To clarify the taxonomic status of E. picteti its characters were compared with literature and determination keys for the whole world. This literature survey and the subsequent study of type specimens revealed that the monotypic Elapotinus is a subjective senior synonym of the monotypic Malagasy pseudoxyrhophiine snake genus Exallodontophis Cadle, 1999 which is characterized by its unique aglyphous dentition. We therefore transfer Elapotinus from the lamprophiid subfamily Aparallactinae to the subfamily Pseudoxyrhophiinae. Furthermore, Elapotinus picteti strongly resembles the Malagasy species Exallodontophis albignaci (Domergue, 1984) in external morphology, coloration and dentition. As a consequence we consider Elapotinus picteti a subjective senior synonym of Exallodontophis albignaci.

    Full Text Available Upon arrival in a host country with considerable ethnic diversity, such as the United States, immigrants are frequently confronted with various different perceptions of local, ethnic, and racial categories and identities. Living in the United States often challenges immigrants to reconsider, modify, or reconstruct their previous identities. This has happened, for example, to Eastern and Southern European immigrants in the late 1800s and early 1900s, and more recently to Korean, Filipino, Mexican and African immigrants from Ghana and Cape Verde, who all have had to reinterpret their identities upon arrival in the United States. Many new immigrants start thinking about themselves in ethnic terms for the first time and (rediscover their ethnicity. Through 20 in-depth interviews with Hungarian immigrants this study explores ethnic identity construction among Hungarians in the United States.

  5. The Design and Implementation of Typed Scheme: From Scripts to Programs

    CERN Document Server

    Tobin-Hochstadt, Sam

    2011-01-01

    When scripts in untyped languages grow into large programs, maintaining them becomes difficult. A lack of explicit type annotations in typical scripting languages forces programmers to must (re)discover critical pieces of design information every time they wish to change a program. This analysis step both slows down the maintenance process and may even introduce mistakes due to the violation of undiscovered invariants. This paper presents Typed Scheme, an explicitly typed extension of PLT Scheme, an untyped scripting language. Its type system is based on the novel notion of occurrence typing, which we formalize and mechanically prove sound. The implementation of Typed Scheme additionally borrows elements from a range of approaches, including recursive types, true unions and subtyping, plus polymorphism combined with a modicum of local inference. The formulation of occurrence typing naturally leads to a simple and expressive version of predicates to describe refinement types. A Typed Scheme program can use the...

    Full Text Available This paper has the goal of making an analysis over the foundation, determination and implication of the economic phenomenon, also over the connections between it and the other parts of social by an interdisciplinary approach in the current world economic context.The start point is my belief in the necessity of rediscovering the economic science basis with regards to the last years: accentuation of inequalities and low-disparities, poverty, the decline of educational system, the incoherence of the monetary evolution, culminating with the economic-financial depression in the last years.All these represent only epiphenomenon, surface manifestation of deeper causes that reveals a certain spiritual decadence, a world crisis of culture and civilization.The real object for the economic knowledge is not the wealth, but the absolute human being.

    The discipline of IR is beginning to grapple with how nature is a condition for, and increasingly and object of, international politics. This chapter narrates how IR actually began with features of the natural world at its heart, then narrowed this down to human nature, before losing sight...... of it almost entirely – only to rediscover it years later as ‘the environment’. A recent revival of realist geopolitics brings geography back in, but misses the environmental angle as well as the Anthropocene idea that due to human influence nature is now more dynamic, more prone to harm and in some ways more...... threatening than before. To theorise a non-anthropocentric IR, one way forward is to develop concepts that integrate the human with the non-human, as some post-human and ‘new materialist’ approaches do. Another strategy is to maintain an analytical distinction between the social and the natural...

    A polynomial algorithm.called Reduction,is presented to discover natural laws by analysing a set of experimental data.instead of a heuristic exploration which,when adopted in BACON,can only lead to rediscovering simple laws.A complex law with multiple variables involved can be discovered by reducing it to a search.This search is so efficient that it does not need any backtracking and is able to cover most of possible laws.A reduction-based discovery system,called DISCOVER 2.0,was developed with a flexible knowledge base and an ability of dealing with imperfect data.The system has been verified to be valid computationally,practically,and theoretically,by discovering a great number o complex laws,and can be also viewed as a leaming engine embodied in any intelligent systems to improve their performance by obtaining a general rule from the accumulated data.

  10. Bicomplex holomorphic functions the algebra, geometry and analysis of bicomplex numbers

    Luna-Elizarrarás, M Elena; Struppa, Daniele C; Vajiac, Adrian

    2015-01-01

    The purpose of this book is to develop the foundations of the theory of holomorphicity on the ring of bicomplex numbers. Accordingly, the main focus is on expressing the similarities with, and differences from, the classical theory of one complex variable. The result is an elementary yet comprehensive introduction to the algebra, geometry and analysis of bicomplex numbers. Around the middle of the nineteenth century, several mathematicians (the best known being Sir William Hamilton and Arthur Cayley) became interested in studying number systems that extended the field of complex numbers. Hamilton famously introduced the quaternions, a skew field in real-dimension four, while almost simultaneously James Cockle introduced a commutative four-dimensional real algebra, which was rediscovered in 1892 by Corrado Segre, who referred to his elements as bicomplex numbers. The advantages of commutativity were accompanied by the introduction of zero divisors, something that for a while dampened interest in this subject. ...

    Phalotris labiomaculatus Lema, 2002 was described based on a single specimen from Porto Franco, south of the Brazilian state of Maranhão, being rediscovered three years later in Mateiros, a municipality in the north of the state of Tocantins, attesting to its occurrence in the cerrado of both banks of the Tocantins River. The discovery of 28 new specimens from other localities during field expeditions (2009-2011) allowed a redescription of the species, adding new data on meristic and morpho-qualitative traits. These results enable a better diagnosis of intraspecific, ontogenetic and sexual variation, consolidating its taxonomic relationships with other species belonging to the nasutus group. The distribution map of P. labiomaculatus, as well as an identification key to the species of the natusus group, are provided. The type-locality is fixed to the municipality of Porto Franco, state of Maranhão.

    If we think about the launch date of Mitomycin C, we could think that this supplement is very much focused on history of Medicine, and, yes, Mitomycin certainly has been a main contributor to the history of Urology. However, it is even more striking to think that even after fifty years of its use by Urologists worlwide, Mitomycin C remains an absolute "Must". The simplicity of use, the efficacy and the tolerability of Mitomycin explain its established role. In fact, "long standing" does not mean "old". The new technologies, introduced progressively in the last decades, have fully confirmed the present and future role of this drug, that is well illustrated in the articles contained in this supplement. I hope you will enjoy reading it and (re)discovering Mitomycin C.

    The article argues for the relevance of rediscovering Wittgenstein in social theory with particular focus on his philosophical method. The article is divided into three parts. Part I gives a brief overview of Wittgenstein’s role in the coming of age of the influential 1980s generation of European...... social theory. Parts II and III discuss Wittgenstein’s method and its significance for social theory. In Wittgenstein’s late philosophy, there are deep and unique insights to be gained about doing theoretical research. These insights can be extended to the social sciences. The article argues...... that the tradition of social theory can benefit from being linked to Wittgenstein’s method which suggests a way of theorizing on the basis of detailed case-knowledge; that it can profit from bringing this method into an explicit relation to existing approaches, styles and tools in social theory.

    2013-07-01

    A recent ground-breaking publication described hypothalamus-driven programmatic aging. As a Russian proverb goes "everything new is well-forgotten old". In 1958, Dilman proposed that aging and its related diseases are programmed by the hypothalamus. This theory, supported by beautiful experiments, remained unnoticed just to be re-discovered recently. Yet, it does not explain all manifestations of aging. And would organism age without hypothalamus? Do sensing pathways such as MTOR (mechanistic Target of Rapamycin) and IKK-beta play a role of a "molecular hypothalamus" in every cell? Are hypothalamus-driven alterations simply a part of quasi-programmed aging manifested by hyperfunction and secondary signal-resistance? Here are some answers.

  17. Green’s functions in classical physics

    CERN Document Server

    Rother, Tom

    2017-01-01

    This book presents the Green’s function formalism in a basic way and demonstrates its usefulness for applications to several well-known problems in classical physics which are usually solved not by this formalism but other approaches. The book bridges the gap between applications of the Green’s function formalism in quantum physics and classical physics. This book is written as an introduction for graduate students and researchers who want to become more familiar with the Green’s function formalism. In 1828 George Green has published an essay that was unfortunately sunken into oblivion shortly after its publication. It was rediscovered only after several years by the later Lord Kelvin. But since this time, using Green’s functions for solving partial differential equations in physics has become an important mathematical tool. While the conceptual and epistemological importance of these functions were essentially discovered and discussed in modern physics - especially in quantum field theory and quantum...

    From July 4 to July 12, the academic community of the Southern belt of France on the Origins, Constituents and EVolution of the Universe (OCEVU) organizes a physics summer camp at the Observatoire de Haute Provence. Thirty teenagers and seven physics teachers from Marseille, Montpellier and Toulouse have been selected to participate in this original outreach event during the summer. The young participants are doing real science by elaborating and analyzing experiments in fundamental physics: they investigate cosmic rays, do astronomical observations, and rediscover the Higgs boson through real data from the ATLAS experiment. To put the young scientists inside the real work atmosphere, physicists Yann Coadou and Pascal Pralavorio will embed a virtual visit to CERN as the culmination of the day dedicated to particle physics. - See more at: http://atlas-live-virtual-visit.web.cern.ch/atlas-live-virtual-visit/2014/Marseille-2-2014.html#sthash.5nsa0vvD.dpuf

    Full Text Available The main line of work is the analysis of dead body in relation to the biopolitical speech or thanatos-political regarding the administration of life and death by the power. In this sense, some ideas will be rediscovered and passages from Michael Foucault, Roberto Esposito, Giorgio Agamben and Judith Butler. On the other hand, death is profound not as biological but as a social death and the different ways to define the living and the dead this social death generates. This social death will be understood as a product of limited human frames that breakout of man to numerous individuals for different reasons. These ideas come out in the light to rebuild the destruction of identities and derealization conducted during the last Argentine dictatorship. From this analysis of the dislocation of identities and bodies will address the dynamic death-dead, is to say ways to litigate the death with the dead.

Such chess-like games have appeared in many different research communities, and methods for solving them......, such as retrograde analysis, have been rediscovered independently. We then revisit Washburn’s deterministic graphical games (DGGs), a natural generalization of chess-like games to arbitrary zero-sum payoffs.

    This paper presents hepatitis disease diagnosis using a Bayesian theory for better understanding of the theory. In this research, we used a Bayesian theory for detecting hepatitis disease and displaying the result of diagnosis process. Bayesian algorithm theory is rediscovered and perfected by Laplace, the basic idea is using of the known prior probability and conditional probability density parameter, based on Bayes theorem to calculate the corresponding posterior probability, and then obtained the posterior probability to infer and make decisions. Bayesian methods combine existing knowledge, prior probabilities, with additional knowledge derived from new data, the likelihood function. The initial symptoms of hepatitis which include malaise, fever and headache. The probability of hepatitis given the presence of malaise, fever, and headache. The result revealed that a Bayesian theory has successfully identified the existence of hepatitis disease.

    1995-06-01

    The contributions to physical anthropology with which Franz Boas is usually credited are in the areas of growth, plasticity of head and body form, and biometric genetics. Such a listing of Boas's contributions overlooks the tremendous amount of research he did with biological variability of Native American populations. The rediscovery of his anthropometric data documents the tremendous investment in time, money, and effort Boas devoted to the topic and provides the opportunity to rediscover his insights into a subject that is of continuing interest. The design of his massive anthropometric survey of native North Americans reveals a concern for population analyses and a rejection of the typological framework of the time. If Boas's ideas had been adopted at the turn of the century, the development of physical anthropology in America might have been much different.

    Full Text Available In recent years a growing interest in regional products could be observed. Products which names point to the place of their origin are bought willingly. Regional products are frequently rediscovered, often found by accident to be finally found with a great efforts in the shops. The specific qualities of the regional products, and especially those of traditional food products, decide about their originality and authenticity. It also proves the fact that they are bought more willingly than mass products. The research on the behaviour of the consumers on the regional products market in Opole area shows that these products are bought willingly. They also create a chance to show and promote the region they are from.

  4. Beyond the Quantum

    CERN Document Server

    Valentini, Antony

    2010-01-01

    At the 1927 Solvay conference, three different theories of quantum mechanics were presented; however, the physicists present failed to reach a consensus. Today, many fundamental questions about quantum physics remain unanswered. One of the theories presented at the conference was Louis de Broglie's pilot-wave dynamics. This work was subsequently neglected in historical accounts; however, recent studies of de Broglie's original idea have rediscovered a powerful and original theory. In de Broglie's theory, quantum theory emerges as a special subset of a wider physics, which allows non-local signals and violation of the uncertainty principle. Experimental evidence for this new physics might be found in the cosmological-microwave-background anisotropies and with the detection of relic particles with exotic new properties predicted by the theory.

    CERN Document Server

    Menezes, Telmo

    2014-01-01

    Networks are a powerful abstraction with applicability to a variety of scientific fields. Models explaining their morphology and growth processes permit a wide range of phenomena to be more systematically analysed and understood. At the same time, creating such models is often challenging and requires insights that may be counter-intuitive. Yet there currently exists no general method to arrive at better models. We have developed an approach to automatically detect realistic decentralised network growth models from empirical data, employing a machine learning technique inspired by natural selection and defining a unified formalism to describe such models as computer programs. As the proposed method is completely general and does not assume any pre-existing models, it can be applied "out of the box" to any given network. To validate our approach empirically, we systematically rediscover pre-defined growth laws underlying several canonical network generation models and credible laws for diverse real-world netwo...

  6. Welcome home, Descartes! rethinking the anthropology of the body.

    Ecks, Stefan

    2009-01-01

    For many scholars, the Cartesian mind/body split is one of the fundamental mistakes of the Western scientific tradition. Anthropologists who study notions of the body in cultures around the world regularly take Descartes as their point of departure. Many also suggest that breaking free from Descartes is politically liberating: if the mindful body could be rediscovered, society could move away from its materialist, positivist, and commodity-fetishizing ways. Beyond the Body Proper is anthropology's best and most comprehensive anti-Cartesian manifesto to date. This volume brings together some of the finest studies on the cultural and historical diversity of bodies and minds. Yet anthropologists' blanket rejection of the mind/body dualism seems politically self-defeating. If anthropologists want to criticize racism, gender hierarchies, or discrimination against disabled people, they need to believe that the mind is independent from the body. In other words, they need to uphold the Cartesian split.

  7. The making of farmland markets——Case study on villages of Hongqi,Liyuantun,Hucun and Xiaogang

    Institute of Scientific and Technical Information of China (English)

    邓大才

    2009-01-01

    Traditional theory holds that a farmland transfer market comes of institution, demand and land lease. In this article, several villages, including Hongqi in Sichuan province, Liyuantun in Hebei province, Hucun in Hunan province, and Xiaogang and its neighboring villages in Anhui province, are studied in terms of the formation and development of their farmland transfer markets. Based on this study, the article concludes that the prerequisite for the making of farmland transfer market is farmland output and returns. It is a necessary condition for the market while demand is a sufficient one. In particular, external capital may promote the demand for farmland and rediscover farmland value. Institution, however, is not the direct reason for the inception of the farmland transfer market, though it ensures that the regulations for this market will be upgraded.

    2013-04-01

    Full Text Available We show how to find a complete set of necessary and sufficient conditions that solve the fixed-parameter local congruence problem of immersions in G-spaces, whether homogeneous or not, provided that a certain kth order jet bundle over the G-space admits a G-invariant local coframe field of constant structure. As a corollary, we note that the differential order of a minimal complete set of congruence invariants is bounded by k+1. We demonstrate the method by rediscovering the speed and curvature invariants of Euclidean planar curves, the Schwarzian derivative of holomorphic immersions in the complex projective line, and equivalents of the first and second fundamental forms of surfaces in R^3 subject to rotations.

  9. An Expressionist Interpretation of Tennessee Williams’ The Two-Character Play

    Institute of Scientific and Technical Information of China (English)

    Danni Lin

    2015-01-01

    Tennessee Williams was a master playwright of the twentieth century, and his plays A Streetcar Named Desire, The Glass Menagerie, and Cat On A Hot Tin Roof are considered among the finest of the American stage. However, his stylistic innovations in his later period had the playwright trapped in negative criticism. Since scholars have largely ignored the study of his late plays, this essay aims to rediscover one of Tennessee Williams’ late plays, The Two-Character Play for its expressionist features: the abstraction of time and place; the symbolic settings and the use of monologues and fragmented utterances. Through the in-depth study of the playwright’s rendering of human tragedies and desperation, the thesis aims to expose the existential crisis of modern man, thus serving the function of catharsis in Tennessee Williams’ tragedies.

    Brozović, Marina; Jacobson, Robert A.

    2017-04-01

    We report on the improved ephemerides for the irregular Jovian satellites. We used a combination of numerically integrated equations of motion and a weighted least-squares algorithm to fit the astrometric measurements. The orbital fits for 59 satellites are summarized in terms of state vectors, post-fit residuals, and mean orbital elements. The current data set appears to be sensitive to the mass of Himalia, which is constrained to the range of GM = 0.13–0.28 km3 s‑2. Here, GM is the product of the Newtonian constant of gravitation, G and the body's mass, M. Our analysis of the orbital uncertainties indicates that 11 out of 59 satellites are lost owing to short data arcs. The lost satellites hold provisional International Astronomical Union (IAU) designations and will likely need to be rediscovered.

    Black phosphorus has been recently rediscovered as a new and interesting two-dimensional material due to its unique electronic and optical properties. Here, we study the linear and nonlinear optical properties of black phosphorus thin films, indicating that both linear and nonlinear optical properties are anisotropic and can be tuned by the film thickness. Then we employ the nonlinear optical property of black phosphorus for ultrafast (pulse duration down to ~786 fs in mode-locking) and large-energy (pulse energy up to >18 nJ in Q-switching) pulse generation in fiber lasers at the near-infrared telecommunication band ~1.5 {\\mu}m. Our results underscore relatively large optical nonlinearity in black phosphorus and its prospective for ultrafast pulse generation, paving the way to black phosphorus based nonlinear and ultrafast photonics applications (e.g., ultrafast all-optical switches/modulators, frequency converters etc.).

  13. Trees, Tight-Spans and Point Configuration

    CERN Document Server

    Herrmann, Sven

    2011-01-01

    Tight-spans of metrics were first introduced by Isbell in 1964 and rediscovered and studied by others, most notably by Dress who gave them this name. Subsequently, it was found that tight-spans could be defined for more general maps, such as directed metrics and distances, and more recently for diversities. In this paper, we show that all of these tight-spans can be defined in terms of point configurations. This provides a useful way in which to study these objects in a unified and systematic way. We also show that by using point configurations we can recover results concerning one-dimensional tight-spans for all of the maps we consider, as well as extend these and other results to more general maps such as symmetric and unsymmetric maps.

  14. Ulcerative and granulomatous enteritis associated with Molineus torulosus parasitism in neotropical primates

    Directory of Open Access Journals (Sweden)

    Max Bruno Magno Bacalhao

    Full Text Available ABSTRACT: This paper reports eleven cases of ulcerative and granulomatous enteritis associated with Molineus torulosus parasitism in different species of neotropical primates of the Sapajus genus. All of the affected monkeys had been apprehended by the environmental police and were being treated in a rehabilitation center for wild animals. The clinical history was weight loss and debility. During the necropsy, several nodules were found on the duodenum and proximal jejunum wall, with ulcers on the adjacent intestinal mucosa, including the nodules in the pancreas of four monkeys. Histologically, eosinophilic granulomas were observed in the small intestine, associated with fibrosis, eggs and adult models of Trichostrongylidae, etiology consistent with Molineus torulosus. This study describes the first cases of parasitism in Sapajus flavius, a species previously considered extinct, but recently rediscovered, and presents the occurrence of M. torulosus in two other species, Sapajus libidinosus and Sapajus apella.

  15. Drug discovery management, small is still beautiful: Why a number of companies get it wrong.

    Science.gov (United States)

    Knutsen, Lars J S

    2011-06-01

    This review provides an account of why more companies involved in drug discovery fail than succeed at releasing the creative energy of gifted scientists, whose invention of new drugs they rely upon to remain at the forefront of the biopharma industry. Initiatives aimed at improving output of new chemical entities often have the opposite effect from that intended and scientists become demotivated. Those with drive, vision and enthusiasm may move to smaller companies to rediscover the spirit of discovery. Some executives fail to understand the psyche of researchers; an applied understanding of the intrinsic motivation of scientists would improve research performance. Entities that focus on smaller autonomous units and sound ethical values will discover the most innovative and successful new drugs. Copyright © 2011 Elsevier Ltd. All rights reserved.

  16. A history of the Allais paradox.

    Science.gov (United States)

    Heukelom, Floris

    2015-03-01

    This article documents the history of the Allais paradox, and shows that underneath the many discussions of the various protagonists lay different, irreconcilable epistemological positions. Savage, like his mentor von Neumann and similar to economist Friedman, worked from an epistemology of generalized characterizations. Allais, on the other hand, like economists Samuelson and Baumol, started from an epistemology of exact descriptions in which every axiom was an empirical claim that could be refuted directly by observations. As a result, the two sides failed to find a common ground. Only a few decades later was the now so-called Allais paradox rediscovered as an important precursor when a new behavioural economic subdiscipline started to adopt the epistemology of exact descriptions and its accompanying falsifications of rational choice theory.

  17. Soil properties and preferential solute transport at the field scale

    DEFF Research Database (Denmark)

    Koestel, J K; Minh, Luong Nhat; Nørgaard, Trine

    An important fraction of water flow and solute transport through soil takes place through preferential flow paths. Although this had been already observed in the nineteenth century, it had been forgotten by the scientific community until it was rediscovered during the 1970s. The awareness...... of the relevance of preferential flow was broadly re-established in the community by the early 1990s. However, since then, the notion remains widespread among soil scientists that the occurrence and strength of preferential flow cannot be predicted from measurable proxy variables such as soil properties or land...... management practices (e.g. Beven, K., 1991, modeling preferential flow - an uncertain future, Preferential Flow, 1-11). In our study, we present evidence that disproves this notion. We evaluated breakthrough curve experiments under a constant irrigation rate of 1 cm/h conducted on 65 soil columns (20 cm...

    2009-10-01

    Cebus flavius is a recently rediscovered species and a candidate for the 25 most endangered primate species list. It was hypothesized that the distribution of C. flavius was limited to the Atlantic Forest, while the occurrence of C. libidinosus in the Rio Grande do Norte (RN) Caatinga was inferred, given its occurrence in neighboring states. As a result of a survey in ten areas of the RN Caatinga, this paper reports on four Cebus populations, including the first occurrence of C. flavius in the Caatinga, and an expansion of the northwestern limits of distribution for the species. This C. flavius population may be a rare example of a process of geographic distribution retraction, and is probably the most endangered population of this species. New areas of occurrence of C. libidinosus are also described. Tool use sites were observed in association with reports of the presence of both capuchin species.

  19. Antibacterial bioagents based on principles of bacteriophage biology: an overview.

    Knoll, Bettina M; Mylonakis, Eleftherios

    2014-02-01

    Bacteriophages were discovered almost a century ago. With the advent of antibiotics, the use of bacteriophages for treatment of infections fell out of favor in Western medicine. In light of the rise of antibiotic resistance, phages and their products (lysins) are rediscovered as antibacterial bioagents. This overview summarizes principles of phage biology and their translation for therapeutic and preventive applications. Examples are presented to highlight their therapeutic promise for prophylaxis and treatment of bacterial infections including multidrug-resistant organisms in humans and animals, and their use as decontaminants of food supplies and environments. Besides research on the in vivo behavior of phages and lysins, dialogues between researchers and regulatory agencies are necessary to publish guidelines for bacteriophage manufacturing and formulation for human use. Only well-designed, double-blind randomized controlled trials will determine if phages and lysins are safe and effective adjuncts or alternatives to antibiotic therapy for infections with multidrug-resistant organisms.

    2009-01-01

    Full Text Available The study of PopI and PopII indicators in galaxies has a profound impact on our understanding of galaxy evolution. Their present (z = 0 ratio suggests that the star formation history of galaxies was primarily dictated by their global mass. Since 1989 Luis Carrasco and I spent most of our sleepless nights gathering H and near infrared surface photometry of galaxies in the local Universe and focused most of our scienti c career on these two indicators trying to convince the community that the mass was the key parameter to their evolution. We were unsuccessful, until in 2004 the Sloan team rediscovered this phenomenon and named it \\downsizing".

    2011-06-01

    Genealogical patterns in different genomic regions may be different due to the joint influence of gene flow and selection. The existence of two subspecies of cultivated rice provides a unique opportunity for analyzing these effects during domestication. We chose 66 accessions from the three rice taxa (about 22 each from Oryza sativa indica, O. sativa japonica, and O. rufipogon) for whole-genome sequencing. In the search for the signature of selection, we focus on low diversity regions (LDRs) shared by both cultivars. We found that the genealogical histories of these overlapping LDRs are distinct from the genomic background. While indica and japonica genomes generally appear to be of independent origin, many overlapping LDRs may have originated only once, as a result of selection and subsequent introgression. Interestingly, many such LDRs contain only one candidate gene of rice domestication, and several known domestication genes have indeed been "rediscovered" by this approach. In summary, we identified 13 additional candidate genes of domestication.

    2010-12-01

    Catatonia has been rediscovered over the last 2 decades as a unique syndrome that consists of specific motor signs with a characteristic and uniform response to benzodiazepines and electroconvulsive therapy. Further inquiry into its developmental, environmental, psychological, and biological underpinnings is warranted. In this review, medical catatonia models of motor circuitry dysfunction, abnormal neurotransmitters, epilepsy, genetic risk factors, endocrine dysfunction, and immune abnormalities are discussed. Developmental, environmental, and psychological risk factors for catatonia are currently unknown. The following hypotheses need to be tested: neuroleptic malignant syndrome is a drug-induced form of malignant catatonia; Prader-Willi syndrome is a clinical GABAergic genetic-endocrine model of catatonia; Kleine-Levin syndrome represents a periodic form of adolescent catatonia; and anti-N-methyl-d-aspartate receptor encephalitis is an autoimmune type of catatonia.

    Allergic diseases are on the increase and current therapies are lacking in efficacy and patient compliance. In recent years, the idea of prophylactic measures, especially for children at high risk for allergy, has become increasingly popular. This review summarizes the available preclinical data for protective allergy vaccines, with a focus on one of the most promising vaccine candidates; mRNA vaccines. Recently, mRNA vaccines have been rediscovered as an alternative to their more prominent counterparts, the DNA vaccines. Allergen-encoding mRNA vaccines elicit long-lasting protection from sensitization, and induce a type of immunity similar to the natural protective response that is acquired in the presence of microbial burden early in life. Owing to their excellent safety profile, they represent the ideal candidates for a vaccine that aims to protect at-risk children who have not yet been sensitized to allergens.

  4. Genome-Wide Association between Transcription Factor Expression and Chromatin Accessibility Reveals Regulators of Chromatin Accessibility

    2017-01-01

    To better understand genome regulation, it is important to uncover the role of transcription factors in the process of chromatin structure establishment and maintenance. Here we present a data-driven approach to systematically characterise transcription factors that are relevant for this process. Our method uses a linear mixed modelling approach to combine datasets of transcription factor binding motif enrichments in open chromatin and gene expression across the same set of cell lines. Applying this approach to the ENCODE dataset, we confirm already known and imply numerous novel transcription factors that play a role in the establishment or maintenance of open chromatin. In particular, our approach rediscovers many factors that have been annotated as pioneer factors. PMID:28118358

    Ruddick, Barry; Gargett, Ann E.

    2003-03-01

    Double-diffusion, the mixing of fluids with two constituents of different molecular diffusivities, was originally discovered in the mid-1800s, forgotten, then rediscovered as an ‘oceanographic curiosity’ a century later. Many oceanographers suspect that double-diffusion has major effects on oceanic water masses and circulation, but direct measurement of the effects has proven difficult. In 1996, a Working Group was formed under the auspices of the Scientific Committee on Ocean Research (SCOR WG108), with the goal to identify progress and barriers to quantifying oceanic double-diffusive fluxes, and make recommendations for further progress. This document gives a brief history of double-diffusion, a review of evidence of its potential effects in the ocean, and gives an overview of the review articles contained in this volume, written by the Working Group members with the above aim in mind.

    Full Text Available Every journey starts from a desire that is at the same time the drive towards appropriation and the awareness of an impossible fulfillment. Through the image of the baby pointing the finger on the map designating an unknown place  – the blank space – that he will want to reach when he will grow up, Joseph Conrad defines a paradigm that will be later recovered and remodeled by other authors. This essay follows the steps of Marlow in Heart of Darkness, in order to rediscover his tracks in actors such as Iain Sinclair and Will Self, in the attempt to build a relationship of contiguous desires to which literature has, over time, given body and substance, a fragile and impermanent substance that is, in a Shakespearian way, the matter which dreams are made by.

  8. Do mechanical doctors dream of electric sheep? Using science fiction to look into the future of public health.

    Science.gov (United States)

    Orizio, G; Gelatti, U

    2010-06-01

    At a first glance, it may seem that science fiction (SF) and public health have not much in common. To enlighten that this could be untrue, this paper starts up from their shared 'community perspective' and focuses on several implications of technological development, which can have a great impact on health and have been in some ways anticipated by SF stories. For example, SF has-more or less directly-discussed about the complex relationship between society, medicine and happiness, and it has anticipated several reflections in the field of advances in genetic technology. Beside tackling specific issues, SF has made a deep reflection about technology itself, the way it frightens and the way it could potentially change people and society. While facing these issues, SF raises questions that can be useful to public health as well, in order to rediscover its role in a world rapidly changing.

  9. A Search for double-lobed radio emission from Galactic Stars and Spiral Galaxies

    Martínez, Abiel Felipe Ortiz

    2016-01-01

    We present a systematic search for two types of very unusual astronomical objects: Galactic stars and spiral galaxies with double radio lobes, i.e. radio emission on opposite sides of the optical object, suggesting the ejection of jets from them. We designed an algorithm to search for pairs of radio sources straddling objects from two unprecedented samples of 878,031 Galactic stars from the Sloan Digital Sky Survey and 675,874 spiral galaxy candidates drawn from the recent literature. We found three new examples of double-lobed radio stars, while for the spiral galaxies we only rediscovered one known such double source, confirming that the latter objects are extremely rare.

    2004-01-01

    In 1919 the Prussian Ministry of Science, Arts and Culture opened a dossier on "Einstein's Theory of Relativity." It was rediscovered by the author in 1961 and is used in conjunction with numerous other subsequently identified 'Einstein' files as the basis of this fascinating book. In particular, the author carefully scrutinizes Einstein's FBI file from 1950-55 against mostly unpublished material from European including Soviet sources and presents hitherto unknown documentation on Einstein's alleged contacts with the German Communist Party and the Comintern. Siegfried Grundmann's thorough study of Einstein's participation on a committee of the League of Nations, based on archival research in Geneva, is also new. This book outlines Einstein's image in politics and German science policy. It covers the period from his appointment as a researcher in Berlin to his fight abroad against the "boycott of German science" after World War I and his struggle at home against attacks on "Jewish physics" of which he was made...

    A database for the entire catalog of the Second Byurakan Survey (SBS) galaxies is presented. It contains new measurements of their optical parameters and additional information taken from the literature and other databases. The measurements were made using Ipg(near-infrared), Fpg(red) and Jpg(blue) band images from photographic sky survey plates obtained by the Palomar Schmidt telescope and extracted from the STScI Digital Sky Survey (DSS). The database provides accurate coordinates, morphological type, spectral and activity classes, apparent magnitudes and diameters, axial ratios, and position angles, as well as number counts of neighboring objects in a circle of radius 50 kpc. The total number of individual SBS objects in the database is now 1676. The 188 Markarian galaxies which were re-discovered by SBS are not included in this database. We also include redshifts that are now available for 1576 SBS objects, as well as 2MASS infrared magnitudes for 1117 SBS galaxies.

    2016-01-01

    Obesity has reached epidemic proportions, leading to severe associated pathologies such as insulin resistance, cardiovascular disease, cancer and type 2 diabetes. Adipose tissue has become crucial due to its involvement in the pathogenesis of obesity-induced insulin resistance, and traditionally white adipose tissue has captured the most attention. However in the last decade the presence and activity of heat-generating brown adipose tissue (BAT) in adult humans has been rediscovered. BAT decreases with age and in obese and diabetic patients. It has thus attracted strong scientific interest, and any strategy to increase its mass or activity might lead to new therapeutic approaches to obesity and associated metabolic diseases. In this review we highlight the mechanisms of fatty acid uptake, trafficking and oxidation in brown fat thermogenesis. We focus on BAT's morphological and functional characteristics and fatty acid synthesis, storage, oxidation and use as a source of energy.

  13. A Spiritual Philosophy of Recovery: Aquinas and Alcoholics Anonymous

    Directory of Open Access Journals (Sweden)

    A. William McVey

    2016-03-01

    Full Text Available The article is an attempt to formulate a Thomistic spiritual philosophy of recovery. The author faces two issues. One, what do recovering alcoholics mean when they say: “I am spiritual, but not religious?” He comes to the conclusion that it means recovering alcoholics are experiencing spiritual healing in their willingness to trust a loving God who has performed a miracle of recovery from alcoholism in their life. As a result of this experience, they are prepared to live a life of virtuous habit. Two, recovering alcoholics have discovered a spiritual second nature of moral character. The author explains why there are many in A.A. who discover that as God comes into their life and they turn to the path of virtue they rediscover religious worship and devotion is essential to the one day at a time journey.

    de Almeida, Jane; da Silva, Cicero Inacio; Suppia, Alfredo; Stalbaum, Brett

    2017-07-01

    The article examines the conditions of production and recognition of scientific cinema in Brazil by comparing three distinct moments and contexts: the first moment takes place in the nineteenth century, and it is related to the contribution of a Brazilian astronomer otherwise little known to Brazilian film scholars, the second addresses Benedito Junqueira Duarte's voluminous mid-twentieth-century filmography, and the third moment documents recent scientific film experiences within ultra high resolution movies transmitted over photonic networks. Future trajectories for aesthetic concerns and practical issues such as the archiving of ultra high definition cinema are usefully informed by these histories of scientific cinema, even as a current generation of multidisciplinary teams including scientists, filmmakers, computer scientists, and network engineers reinvent, rediscover, and necessarily expand the scientific cinema toward concerns of real time collaboration and teaching.

    Hartmann, W. K.

    1981-01-01

    Early selenographers resolved individual structural components of multi-ring basin systems but missed the underlying large-scale multi-ring basin patterns. The recognition of multi-ring basins as a general class of planetary features can be divided into five steps. Gilbert (1893) took a first step in recognizing radial 'sculpture' around the Imbrium basin system. Several writers through the 1940's rediscovered the radial sculpture and extended this concept by describing concentric rings around several circular maria. Some reminiscences are given about the fourth step - discovery of the Orientale basin and other basin systems by rectified lunar photography at the University of Arizona in 1961-62. Multi-ring basins remained a lunar phenomenon until the fifth step - discovery of similar systems of features on other planets, such as Mars (1972), Mercury (1974), and possibly Callisto and Ganymede (1979). This sequence is an example of gestalt recognition whose implications for scientific research are discussed.

    This Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) image of Mt. Vesuvius, Italy was acquired September 26, 2000. The full-size false-color image covers an area of 36 by 45 km. Vesuvius overlooks the city of Naples and the Bay of Naples in central Italy. (Popocatepetl and Mount Fuji are other volcanos surrounded by dense urban areas.) In 79 AD, Vesuvius erupted cataclysmically, burying all of the surrounding cites with up to 30 m of ash. The towns of Pompeii and Herculanaeum were rediscovered in the 18th century, and excavated in the 20th century. They provide a snapshot of Roman life from 2000 years ago: perfectly preserved are wooden objects, food items, and the casts of hundreds of victims. Vesuvius is intensively monitored for potential signs of unrest that could signal the beginning of another eruption. Image courtesy NASA/GSFC/MITI/ERSDAC/JAROS, and U.S./Japan ASTER Science Team

    2016-01-01

    Quinoa (Chenopodium quinoa Willd.) was first domesticated in Andean countries over 7000 years ago. Following the Spanish conquest, quinoa was rejected as "Indian food." After centuries of neglect, the potential of quinoa was rediscovered during the second half of the 20th century. Since then......, the number of countries importing quinoa increased, with new producers appearing on the map and quinoa now being cultivated in areas outside the Andean countries. The geographical increase in distribution of quinoa has highlighted the difficulty of access to quality seed, which is a key factor for testing...... the crop outside the Andes. In this context, research partnerships have helped promote the exchange of quinoa germplasm and have allowed trials to be undertaken in non-traditional areas of cultivation. The number of countries growing the crop has increased rapidly from eight in 1980, to 40 in 2010...

    Analyses of archaeological materials aim to rediscover the know-how of Prehistoric people by determining the nature of the painting matter, its preparation mode, and the geographic origin of its raw materials. This study deals with identification of manganese oxides in black pigments by micro-XANES (X-ray absorption near-edge structure) based on previous TEM (transmission electron microscopy) studies. Complex mixtures of the manganese oxides studied are present in some of mankind's oldest known paintings, namely those from the caves of Lascaux (Dordogne, France) and Ekain (Basque country, Spain). Scarce manganese oxide minerals, including groutite, hausmannite, and manganite, were found for the first time in Paleolithic art at these archaeological sites. Because there are no known deposits of such minerals in these areas, more distant origins and trade routes are inferred. The closest known Mn-rich geological province for Lascaux is the central Pyrenees, which is {approx} 250 km from the Dordogne area.

  20. 'The confucian ethic and the spirit of capitalism': narratives on morals, harmony, and savings in the condemnation of conspicuous consumption among chinese immigrants overseas

    Directory of Open Access Journals (Sweden)

    Rosana Pinheiro-Machado

    Full Text Available From a reflection on market and consumption changes in contemporary China, this article discusses the Chinese diaspora's role in rediscovering "traditional" values, especially those related to notions of harmony, hard work and savings, based on the religious and philosophic Confucian heritage. If, on one hand, we observe today deep consumerism among the young generations living in China, on the other hand, the denial of conspicuous consumption appears as a distinctive feature among Chinese immigrants living in Ciudad del Este (Paraguay, where they work as importers and distributors of goods made in China. Due to these characteristics, I outline a comparison with the Calvinist ethic as analyzed by Max Weber, drawing approaches and differences between Protestantism and Confucianism regarding conspicuous spending, work ethic and wealth accumulation.

  1. Exploring the S-Matrix of Massless Particles

    CERN Document Server

    Benincasa, Paolo

    2011-01-01

    We use the recently proposed generalised on-shell representation for scattering amplitudes and a consistency test to explore the space of tree-level consistent couplings in four-dimensional Minkowski spacetime. The extension of the constructible notion implied by the generalised on-shell representation, i.e. the possibility to reconstruct at tree level all the scattering amplitudes from the three-particle ones, together with the imposition of the consistency conditions at four-particle level, allow to rediscover all the known theories and their algebra structure, if any. Interestingly, this analysis seems to leave room for high-spin couplings, provided that at least the requirement of locality is weakened. We do not claim to have found tree-level consistent high-spin theories, but rather that our methods show signatures of them and very likely, with a suitable modification, they can be a good framework to perform a systematic search.

    Uboha, Nataliya; Hochster, Howard S

    2016-01-01

    TAS-102, a novel antimetabolite combination chemotherapy agent, consists of a rediscovered antimetabolite agent, trifluorothymidine (trifluridine) combined with the metabolic inhibitor of thymidine phosphorylase, tipiracil, in a 1:0.5 molar ratio. Mechanism of action studies suggest that this agent works by incorporation into DNA. Both preclinical and clinical studies demonstrate that this agent is noncross-resistant with 5-fluorouracil. Tipiracil may also have antiangiogenic effects through inhibition of thymidine phosphorylase. Recent randomized Phase II and III trials demonstrate clinical activity (improved progression-free survival, time to decrease in performance status, prolonged overall survival) in metastatic colorectal cancer refractory to all standard agents. Monotherapy with TAS-102 has now been approved for this indication in Japan and in the USA.

  3. Gender and Posthuman

    Directory of Open Access Journals (Sweden)

    Redazione La Camera blu

    2015-12-01

    Full Text Available This issue of the Camera Blu is an important contribution to the study of gender and the posthuman for different reasons. Currently, posthumanism has become a highly fashionable academic trend. Considering that anthropocentrism is leading to an environmental eco-disaster so deep as to endanger the very survival of the human species, this breakthrough in academia is a great opportunity for social reform. On the other hand, the hegemonic appropriation of the posthumanist discourse is obscuring the core meaning of the posthuman with ironic consequences. The “neutral” subject, that is male, white, heterosexual, Western etc., is rediscovering the posthuman in the name of the Father, in an ahistorical reconstruction in which the decisive contribution of feminism is gradually superseded by names of male theorists, to ensure a phallocratic genealogy to Posthuman Studies. Is this a defeat of the posthuman? Not at all. The interest that posthumanism is attracting can only bring satisfaction to scholars who have been working for years to its promotion. And still, because in this proliferation of the posthuman, the meaning of the term is taking on different shades, colors and nuances, it is crucial to rediscover its roots. Posthumanism stems from Feminism: forgetting this genealogical debt means giving up the deepest identity of the posthuman. This issue of the Camera Blu wishes to emphasize this powerful genealogy, and to lay a platform for further development of gender through the posthuman, and of the posthuman through gender, reflecting on the possible futures of gender in relation to the human and the posthuman species.

    Arsenic trioxide has been used in traditional Chinese medicine for over 5000 years, but lost its appeal due to its toxicity. It was rediscovered in western medicine and enjoyed a renaissance from 1830 to 1930, as the first effective chemotherapy against syphilis, parasites and leukaemia. These years were also a time of political turmoil in China. The Nanking treaty (29 August 1842) turned Hong Kong into a colony, while the Xinhai Revolution (10 October 1911) gave birth to a republic of China. Arsenic returned to China and Hong Kong with the establishment of the first medical schools from 1887 to 1920. Until 1950, oral arsenic trioxide was the standard anti-leukaemic treatment in Queen Mary Hospital. The advent of alkylating chemotherapeutic agents replaced arsenic trioxide in Hong Kong and around the world. In the 1970s, however, the specific activity of arsenic trioxide against acute promyelocytic leukaemia was re-discovered during the Cultural Revolution in Harbin, China. In 1997, Hong Kong was returned to China. In the same year, arsenic trioxide returned to the world stage. Intravenous arsenic trioxide became the worldwide standard therapy for relapsed acute promyelocytic leukaemia. Oral administration of arsenic trioxide was revived in Hong Kong in 2000. This resulted in the first locally produced, registered, patented prescription drug in Hong Kong. Pending imminent manufacture, this product is poised to revolutionise acute promyelocytic leukaemia care and may hold the key to saving the lives of acute promyelocytic leukaemia patients worldwide. The remarkable journey of arsenic in the setting of medical history of China and Hong Kong is reviewed.

    Recent biotic surveys in subalpine shrubland on Haleakala¯ Volcano, Maui, Hawai‘i, have resulted in rediscovery of several species of carabid beetles previously known only from their nineteenth-century type specimens. Blackburnia lenta (Sharp), described from specimens collected just below Haleakala¯ summit in 1894, was found at lower elevational sites ranging from 2,400 to 2,750 m. Mecyclothorax rusticus Sharp, last seen in 1896, and M. nubicola (Blackburn), collected only in 1878, were also rediscovered in that vicinity. Recent collections of B. lenta contradict the U.S. Fish and Wildlife Service’s previous classification of this species as one likely to be extinct. Nevertheless, B. lenta’s known distribution comprises only 145 ha within an elevational zone that is bounded above and below by unicolonial populations of the invasive alien Argentine ant, Linepithema humile (Mayr). The known recent collections of M. rusticus and M. nubicola also occurred outside the distributional range of the Argentine ant. Mature eggs held in the lateral oviducts of B. lenta females averaged 1.4 the volume of the largest eggs previously reported among 13 species of Blackburnia. We hypothesize that the giant eggs of B. lenta result from selective forces favoring large, well-nourished developing and hatched first-instar larvae, consistent with a patchy distribution of suitable microhabitat and prey in the subalpine Haleakala¯ landscape. The specialized life history of B. lenta, and coincidence of distributional limits of the three rediscovered carabid species with range limits of the Argentine ant populations suggest that all would be jeopardized by future distributional expansion of Argentine ant. These intersecting phenomena compel us to conclude that B. lenta, M. nubicola, and M. rusticus are appropriate candidates for I.U.C.N. threatened species designation, pending further studies of their geographic ranges and historical trends in abundance.

  7. Geomorphology's role in the study of weathering of cultural stone

    Great monumental places—Petra, Giza, Angkor, Stonehenge, Tikal, Macchu Picchu, Rapa Nui, to name a few—are links to our cultural past. They evoke a sense of wonderment for their aesthetic fascination if not for their seeming permanence over both cultural and physical landscapes. However, as with natural landforms, human constructs are subject to weathering and erosion. Indeed, many of our cultural resources suffer from serious deterioration, some natural, some enhanced by human impact. Groups from the United Nations to local civic and tourism assemblies are deeply interested in maintaining and preserving such cultural resources, from simple rock art to great temples. Geomorphologists trained in interacting systems, process and response to thresholds, rates of change over time, and spatial variation of weathering processes and effects are able to offer insight into how deterioration occurs and what can be done to ameliorate the impact. Review of recent literature and case studies presented here demonstrate methodological and theoretical advances that have resulted from the study of cultural stone weathering. Because the stone was carved at a known date to a "baseline" or zero-datum level, some of the simplest methods (e.g., assessing surface weathering features or measuring surface recession in the field) provide useful data on weathering rates and processes. Such data are difficult or impossible to obtain in "natural" settings. Cultural stone weathering studies demonstrate the importance of biotic and saline weathering agents and the significance of weathering factors such as exposure (microclimate) and human impact. More sophisticated methods confirm these observations, but also reveal discrepancies between field and laboratory studies. This brings up two important caveats for conservators and geomorphologists. For the conservator, are laboratory and natural setting studies really analogous and useful for assessing stone damage? For the geomorphologist, does

    Ankle sprains continue to pose a significant burden to the individual athlete, as well as to society as a whole. However, despite ankle sprains being the single most common sports injury and despite an active approach by various Dutch organisations in implementing preventive measures, large-scale community uptake of these preventive measures, and thus actual prevention of ankle sprains, is lagging well behind. In an attempt to bridge this implementation gap, the Dutch Consumer Safety Institute VeiligheidNL developed a freely available interactive App ('Strenghten your ankle' translated in Dutch as: 'Versterk je enkel; available for iOS and Android) that contains - next to general advice on bracing and taping - a proven cost-effective neuromuscular program. The 'Strengthen your ankle' App has not been evaluated against the 'regular' prevention approach in which the neuromuscular program is advocated through written material. The aim of the current project is to evaluate the implementation value of the 'Strengthen your ankle' App as compared to the usual practice of providing injured athletes with written materials. In addition, as a secondary outcome measure, the cost-effectiveness will be assessed against usual practice. The proposed study will be a randomised controlled trial. After stratification for medical caregiver, athletes will be randomised to two study groups. One group will receive a standardized eight-week proprioceptive training program that has proven to be cost-effective to prevent recurrent ankle injuries, consisting of a balance board (machU/ MSG Europe BVBA), and a traditional instructional booklet. The other group will receive the same exercise program and balance board. However, for this group the instructional booklet is exchanged by the interactive 'Strengthen your ankle' App. This trial is the first randomized controlled trial to study the implementation effectiveness of an App for proprioceptive balance board training program in comparison to

    Full Text Available In 1865, Gregor Mendel presented the lectures 'Experiments in Plant Hybridization' concerning his results from cross-breeding experiments with different types of garden pea, performed in his monastery garden in Brno. Mendel studied easily observed pairs of opposite traits, such as purple or white flower, and discovered dominant and recessive traits. He concluded that parents pass separate and distinct factors (today called genes on to their offspring that are responsible for inherited traits. However, the scientific community did not understand that; indeed it was the beginning of what becomes genetics. The lectures published in 1866, Mendel sent to more than 30 biologists across Europe, but almost no one commented them. In the next 35 years, these papers were only three times cited. The genetics became more important at the beginning of the 20th century, when three different research groups (Hugo de Vries, Carl Erich Correns and Erich von Tschermak with their co-workers independently re-discovered Mendel's Laws of inheritance. However, as soon as the work was rediscovered, it created controversy. The closeness of Mendel's experimental observations to those predicted by his theories has led to numerous articles and ongoing debate about whether the data could have been obtained in the published form without some falsification. There have been many plausible arguments made for and against this view by a range of eminent geneticists and statisticians. Some have gone so far, as to suggest that the theories ensued from Mendel's two laws were not even correctly formulated in his original paper. The strongest supporters of Mendel's theory became biologist William Bateson and zoologist and geneticist Thomas Hunt Morgan. Morgan argued that genes are located on chromosomes and that the cells chromosomes hold the actual hereditary material, thus created what is now known as classical genetics. For his discovery concerning the role play by the chromosome in

    A key challenge in understanding the feedback mechanism of AGN in Brightest Cluster Galaxies (BCGs) is the inherent rarity of catching an AGN during its strong outburst phase. This is exacerbated by the ambiguity of differentiating between AGN and clusters in X-ray observations. If there is evidence for an AGN then the X-ray emission is commonly assumed to be dominated by the AGN emission, introducing a selection effect against the detection of AGN in BCGs. In order to recover these 'missing' clusters, we systematically investigate the colour-magnitude relation around some ~3500 ROSAT All Sky Survey selected AGN, looking for signs of a cluster red sequence. Amongst our 22 candidate systems, we independently rediscover several confirmed systems, where a strong AGN resides in a central galaxy. We compare the X-ray luminosity to red sequence richness distribution of our AGN candidate systems with that of a similarly selected comparison sample of ~1000 confirmed clusters and identify seven 'best' candidates (all ...

  11. An introduction to environmental biophysics

    The study of environmental biophysics probably began earlier in man's history than that of any other science. The study of organism-environment interaction provided a key to survival and progress. Systematic study of the science and recording of experimental results goes back many hundreds of years. Ben­ jamin Franklin, the early American statesman, inventor, printer, and scientist studied conduction, evaporation, and radiation. One of his observations is as follows: My desk on which I now write, and the lock of my desk, are both exposed to the same temperature of the air, and have therefore the same degree of heat or cold; yet if I lay my hand successively on the wood and on the metal, the latter feels much the coldest, not that it is really so, but being a better conductor, it more readily than the wood takes away and draws into itself the fire that was in my skin. 1 Franklin probably was not the first to discover this principle, and certainly was not the last. Modem researchers rediscover this principle f...

    Prof. Dr. Richard Dipper initiated the Summer School 1998 with Dr. Bernd Ackermann at the University of Stuttgart. Dealing with the representation theory of $\\mathfrak{S}_{n}$ there was only a loose conncetion via prime numbers to Ramanujan's "lost notebook" that had been published a year earlier. Naturally this caught attention and I asked questions until the limit $$\\limsup\\limits_{x\\to\\infty}\\frac{\\sigma(x\\cdot n)}{xn\\cdot\\ln\\ln(x\\cdot n)}=e^{\\gamma}$$ was found to be an essential key to attack the Riemann hypothesis (RH) after I had studied several papers, e.g. Gr\\"onwall (1913) in the first place, in particular in combination with Robin (1984) and Alaoglu and Erd\\H{o}s (1944). Due to a lack of number theoretic expertise we didn't believe to be elect for this. So everybody did something else. Additionally I was prevented from further investigation due to a severe car accident later. However, I'm happy that I've been able to rediscover my early academic ideas now, again leading to an equivalent of RH that ...

    Full Text Available A narrative of church life today. We live in a time when survival seems to be the biggest concern of most mainline congregations and denominations. How can the church possibly survive? This is a question that is asked in almost every corner of the institution. Since the 1960s, numerous books and articles have been published, trying to get a handle on why the mainline churches are in decline. Whatever the cause may be, decline is causing great fear and anxiety in the mainline churches. In an effort to answer the underlying question: ‘What shall we do to turn the situation around?’, some churches are simply trying to ‘market’ themselves and their message. Others try to ’do’ church differently. Some try to rediscover the purpose of the church, et cetera. Cheryl Peterson argues that churches are, in fact, facing an ecclesial crisis, that is much more than a crisis of declining numbers and membership. There is a deeper and more basic issue that must be explored, one that has to do with the church’s theological identity, and that is: what it means to be church? This article is about the question: Who is the church? And it answers the question on the basis of Peterson’s thesis by means of a narrative of the church that commences with the Spirit.

    We screened 32 ophthalmology journals that had published articles during the period from 1850 through 1949 to identify top-cited articles in the field of ophthalmology (hereafter referred to as citation classics) using the online database Science Citation Index Expanded (Thompson Reuters, Chicago, Illinois). The 101 most frequently cited articles were published in 16 journals. Archives of Ophthalmology had the most top-cited articles (n = 31), followed by American Journal of Ophthalmology (n = 24) and Albrecht von Graefe's Archiv für Ophthalmologie (n = 9). These articles originated from 14 countries, with the United States publishing the majority (n = 58). Most of the citation classics are clinical studies on topics such as rubella cataract, retinopathy of prematurity, keratoconjunctivitis sicca, sympathetic ophthalmia, and the first report of eponymous diseases (eg, Leber hereditary optic neuropathy, Duane retraction syndrome, and Stargardt disease). A considerable number of these articles were ignored initially and for several decades after publication, but, like the classic fairy tale Sleeping Beauty, they have been rediscovered. Our study provides a historical perspective on the classic papers in the literature that are still influential in ophthalmology.

    In 2010 we rediscovered the complete set of meteorological observation protocols made by Jens Esmark (1762-1839) during his years of residence in the Norwegian capital of Oslo (then Christiania). From 1 January 1816 to 25 January 1839, Esmark at his house in Øvre Voldgate in the morning, early afternoon and late evening recorded air temperature with state-of-the-art thermometers. He also noted air pressure, cloud cover, precipitation and wind directions, and experimented with rain gauges and hygrometers. From 1818 to the end of 1838 he twice a month provided weather tables to the official newspaper Den Norske Rigstidende, and thus acquired a semi-official status as the first Norwegian state meteorologist. This paper evaluates the quality of Esmark's temperature observations and presents new metadata, new homogenization and analysis of monthly means. Three significant shifts in the measurement series were detected, and suitable corrections are proposed. The air temperature in Oslo during this period is shown to exhibit a slow rise from 1816 towards 1825, followed by a slighter fall again towards 1838.

    Full Text Available The phallogocentric structure of language privileges the male in construction of meaning throughout the patriarchal history which allows no place for feminine writing. Opposing what Lacan calls as phallogocentric discourse, poststructuralist feminists exhort to what Cixous terms as “écriture feminine” as the inscription of female difference in language and text. Therefore, viewing women's difference as a source (of imagery rather than a point of inferiority to men, Rich rediscovers female experiences in her poems through using “écriture feminine” and thus exhibits the productivity and plurality of women’s language. Hence, the present study, looking from the perspective of Cixous’s “écriture feminine,” aims at analyzing female modes of writing in Rich’s poems. The main finding of the research is that, through using genuine female forms of expression as opposed to phallogocentric structure of expression, Rich brings into being the symbolic weight of female consciousness, illustrating the oppressive forces that obstruct female expression.

    We report the discovery by the Arecibo Legacy Fast ALFA (ALFALFA) survey of eight HI features not coincident with stellar counterparts in the Virgo Cluster region. All of the HI clouds have cz < 3000 km/s and, if at the Virgo distance, HI masses between 1.9 x 10**7 and 1.1 x 10**9 solar masses. Four of the eight objects were reported or hinted at by previous studies and "rediscovered" by ALFALFA. While some clouds appear to be associated with optical galaxies in their vicinity, others show no clear association with a stellar counterpart. Two of them are embedded in relatively dense regions of the cluster and are associated with M49 and M86; they were previously known. The others are mostly located in peripheral regions of the cluster. Especially notable are a concentration of objects towards the so-called M cloud, 3 to 5 degrees to the NW of M87, and a complex of several clouds projected roughly halfway between M87 and M49. The object referred to as VIRGOHI21 and proposed to be a "dark galaxy" is also dete...

  18. THE PARISH AS AN OPEN SOCIETY

    2015-04-01

    Full Text Available In all the thrill of the modern definitions of the social function of everyday life, we often forget about the basic human organizations that created the social cohesion which survived over the history during difficult times. A sort of memory aneurysm prevents us from rediscovering those communicational structures that created the real human community, which generated it free of any ideologies and fanaticisms, which raised it in the modern social network. The parish, humble social community based on the confession of the same faith and the stretching of a given geography, was mocked, eluded and informally deformed. It remains, though, one of the greatest miracles of the sociology of social organization, one of the communicational categories preserved, it seems, despite the evolution of virtual communication. It is enough to cross, for instance, the great highways of modern Europe, as well as the British area to see that the names of cities, thousands of them, are related to the Christian culture of the place. A certain saint or boards which attest the Christian past of the place, marking points of the spiritual amperage of the area, are lumps in an informal network that proves that the parish remains one of the sociological categories of communication that remains deeply implemented in the mentality of the modern man. Even if it lacks the same spiritual or cultural connotation, it remains the model of the open society, placed in the interval of the new models, destructured from the very moment of their hermeneutical assertion.

    Full Text Available According to the New Testament ‘the love of money’ is a root of all evil and a no-go for church elders. After the financial crises this warning and old virtues are re-discovered. The articles analyse virtues and vices dealing with money. Consulting insights from old texts such as Aristotle, the New Testament, Thomas Aquinas and modern authors like Comte-Sponville and Sofsky we develop a classification with two virtues, generosity and frugality, and two corresponding vices, meanness and greed. Due to the different facets of the topic we discuss these virtues and vices by combining explanations from philosophy, theology, psychology, sociology, and economy. These discussions are led by the question “how can we live these virtues in our modern society?”. Especially, we discuss the challenge of living frugal in a market economy, which regards greed as a ‘virtue in disguise’. doi: 10.7833/111-1-34

    2014-05-01

    Full Text Available Both strands of human mtDNA are transcribed in continuous, multigenic units that are cleaved into the mature rRNAs, tRNAs, and mRNAs required for respiratory chain biogenesis. We sought to systematically identify nuclear-encoded proteins that contribute to processing of mtRNAs within the organelle. First, we devised and validated a multiplex MitoString assay that quantitates 27 mature and precursor mtDNA transcripts. Second, we applied MitoString profiling to evaluate the impact of silencing each of 107 mitochondrial-localized, predicted RNA-binding proteins. With the resulting data set, we rediscovered the roles of recently identified RNA-processing enzymes, detected unanticipated roles of known disease genes in RNA processing, and identified new regulatory factors. We demonstrate that one such factor, FASTKD4, modulates the half-lives of a subset of mt-mRNAs and associates with mtRNAs in vivo. MitoString profiling may be useful for diagnosing and deciphering the pathogenesis of mtDNA disorders.
