The noncompliant patient: a Kantian and Levinasian response.

PubMed

Burcher, Paul

2012-02-01

When a patient fails to follow the advice or prescription of a physician, she is termed to be "noncompliant" by the medical community. The medical community's response to and understanding of patient noncompliance fails to acknowledge noncompliance as either a relational failure between physician and patient or as a patient choice. I offer an analysis of Immanuel Kant and Emmanuel Levinas that refocuses the issue of noncompliance by examining the physician role, the doctor-patient relationship, and the nature of responsibility.

2011-05-01

Press coverage of psychology by the New York Times was examined for the Progressive Era. Following a period in which psychology was associated with spiritualism, psychoanalysis, and the Emmanuel movement, the Times gave editorial preference to reports about psychology's applications. Reaching an audience that was both affluent and influential, the topics emphasized by the Times included the lie detector, psychological applications in the work place, mental tests, and child psychology. These areas reflected issues of social concern to Progressives, publicized the rise of the psychologist as expert, and aided psychology in its challenge to common sense.

Finding Hope in the Face-to-Face.

Edgoose, Jennifer Y C; Edgoose, Julian M

What does it mean to look into the face of a patient who looks back? Face-to-face encounters are at the heart of the patient-clinician relationship but their singular significance is often lost amid the demands of today's high-tech, metric-driven health care systems. Using the framework provided by the philosopher and Holocaust survivor Emmanuel Levinas, the authors explore the unique responsibility and potential for hope found only in face-to-face encounters. Revisiting this most fundamental attribute of medicine is likely our greatest chance to reclaim who we are as clinicians and why we do what we do. © 2017 Annals of Family Medicine, Inc.

Integrated palliative care (IPC) involves bringing together administrative, organisational, clinical and service aspects in order to achieve continuity of care between all actors involved in the care network of patients receiving palliative care (PC) services. The purpose of this study is to identify literature on IPC in the Spanish context, either in cancer or other advanced chronic diseases. Systematic review of the literature about IPC published in Spain between 1995 and 2013. Sources searched included PubMed, Cochrane Library, Cinahl, the national palliative care Journal (Medicina Paliativa), and Google. Evidence on IPC in care models, pathways, guidelines and other relevant documents were searched. Additionally, data were included from expert sources. Elements of IPC were considered based on the definition of IPC and the Emmanuel´s IPC tool. The main inclusion criterion was a comprehensive description of PC integration. Out of a total of 2,416 titles screened, 49 were included. We found two models describing IPC interventions achieving continuity and appropriateness of care as a result, 12 guidelines or pathways (most of them with a general approach including cancer and non-cancer and showing a theoretical IPC inclusion as measured by Emmanuel's tool) and 35 other significant documents as for their context relevance (17 health strategy documents, 14 analytical studies and 4 descriptive documents). These last documents comprised respectively: regional and national plans with an IPC inclusion evidence, studies focused on IPC into primary care and resource utilisation; and descriptions of fruitful collaboration programmes between PC teams and oncology departments. The results show that explications of IPC in the Spanish literature exist, but that there is insufficient evidence of its impact in clinical practice. This review may be of interest for Spanish-speaking countries and for others seeking to know the status of IPC in the literature in their home nations.

How might Levinas' concept of the other's priority and Derrida's unconditional hospitality contribute to the philosophy of the modern hospice movement?

PubMed

Floriani, Ciro Augusto; Schramm, Fermin Roland

2010-06-01

Hospitality is commonly referred as one of the meanings of hospes, the Latin word which is also the root of hospice. This article explores the semantics of the word hospice - the seal of identity of modern hospice movement - and attempts to integrate the meaning of hospitality into the modern hospice movement, understood as unconditional reception. Therefore, the article analyzes the concept of unconditional hospitality, developed by Jacques Derrida and that of ethical responsibility proposed by Emmanuel Levinas based on the phenomenological experience of the other. From this point of view, these two concepts tie in with the meaning of hospice, bringing substantial grounding elements to the hospice movement for the construction of a protective ethos.

[In the beginning was a relationship].

Vanbelle, Guido

2008-01-01

Judgment and actions based on scientific evidence are modified by the unique caregiver-patient relationship. Caregivers relying exclusively upon "rational" decisions in line with evidence-based clinical recommendations avoid their relational responsibility. The "noble" purpose illustrates that decisions to treat can be at the same time pointless and valuable. Dia (through) - logue (knowledge) makes it possible to go beyond informed consent, which holds caregivers responsible for providing information and patients for the decision to treat. Finally, where healing is no longer achievable and autonomy dies away, compassion rather than therapeutic tenacity might be the answer. These examples are explained corresponding to the philosophical ideas of respectively Emmanuel Levinas en Roger Burgraeve (noble purpose), Martin Buber (dialogical thinking) and Daniel C. Dennett (autonomy loss).

CAPE CANAVERAL, Fla. - NASA's Johnson Space Center Aerospace Engineer Jeff Hagen, left, and engineering intern Emmanuel Nyangweso attach rotors to the top of a model capsule ahead of tests inside the Vehicle Assembly Building at NASA's Kennedy Space Center in Florida. The design would give a capsule the stability and control of a helicopter, but would not be powered. Instead, the wind passing over the rotors as the capsule descends would make the blades turn, a process called auto-rotation. The intent is to give real spacecraft a soft landing with enough control that they could touch down anywhere in the world, whether it be a runway or parking lot. In other words, wherever a helicopter could land, a spacecraft could land, too. Photo credit: NASA/Kim Shiflett

'Welcoming the Other': psychodrama in an acute inpatient unit.

Michael, Lorraine

2016-02-01

In this article, the author uses the leitmotifs inherent in a critically acclaimed film and in the philosophy of Emmanuel Levinas as a backdrop for discussion around how we encounter the humanity in the Other and its particular relevance for psychiatry. She proceeds to describe the existential underpinnings of psychodrama and demonstrates how she has been directing a psychodrama group, 'Theatre of Life', which has been operating for well over a decade within a public mental health system, acute inpatient unit. Through the ensuing discussion, she illustrates how the humanistic ethic of 'welcoming the Other' is actualised in the 'here-and now' of the psychodrama group psychotherapy process. A thematic analysis derived from group-members' evaluation of each session illuminates their felt sense depicting the ethic in action. © The Royal Australian and New Zealand College of Psychiatrists 2015.

[Ethics as first philosophy: the ethics of responsibility as a rationale for health care].

PubMed

Belli, Laura Florencia; Quadrelli, Silvia

2010-01-01

The origins of bioethics as a discipline arouse from the need to provide an answer to new ethical questions generated as a result of technological advances in the health field and the new arenas in which biomedical research began to develop. Discussions were first focused on the relevance of the applicability of new technologies and the need to redefine a number of concepts related to the beginning and end of life. Then, over the years, this discipline was shaped and reconfigured incorporating issues related to the process of decision making in daily medical care, patient rights, protection of their freedoms and obligations of medical professionals, among others. The purpose of this essay is to reflect upon the ethical foundations of health care, trying to provide an answer to the question "why movide care" in light of the thought of Emmanuel Lévinas.

Do humans own themselves ? Questions concerning their self-determination and free disposition of self.

PubMed

Muhrel, Eric

2003-01-01

The debate about voluntary euthanasia arises (essentially) from a fundamental anthropological question: do humans own themselves? An answer to this question is developed which starts out from the foundational ethic of Emmanuel Levinas. The metaphysics of the countenance of the Other in Levinas is then related to Karl Rahner's description of God as the absolute enigma which is fated towards us. God, understood as that enigma, is experienced for us concretely in our relationship to the countenance of our neighbor, the other human being. Our being thus referred to the absolutely Other in the countenance of the other human grounds not only the non-disposability of that other human being, but also the non-disposability of myself. This is the decisive point for how one should think about euthanasia. In contrast to the (so-called) voluntary euthanasia, accompaniment in dying takes account of that dialogical constitution of man.

Some reflections on human needs, peace, transculturality and Igbo proverbs in the light of Emmanuel Edeh's African philosophy.

PubMed

Prstačić, Miroslav

2015-03-01

Within the framework of a transcultural, psychodynamic and holistic approach, Edeh's concept of Man as Mma-di (in Igbo language in Nigeria, mma-di = good that is, and mma-ndu = the beauty of Life) is presented as the nucleus of his philosophical articulation from an African metaphysical-anthropological perspective. In this context, some reflections are shown on the following topics: human creativity and peace... of mind, body and soul, as existential values and entity in bioethics; aspects of Edeh's philosophy and his work on the peace in the world; transculturality and Igbo proverbs shaped in form of Japanese Haiku poetry. These reflections emphasize the importance of induced aesthetic mental state in the subject, which derives from biological impulses but from archetypal and symbolic value of the object and continuously enter into a metaphysical experience as a form of life energy and human existential need. In this context, we discover also Edeh's philosophy as a new stimulus for further reflections and research on human life potentials, creativity, peace and Man's cosmic responsibility.

Push, pull, and reverse: self-interest, responsibility, and the global health care worker shortage.

PubMed

Kirby, Katherine E; Siplon, Patricia

2012-06-01

The world is suffering from a dearth of health care workers, and sub-Saharan Africa, an area of great need, is experiencing the worst shortage. Developed countries are making the problem worse by luring health care workers away from the countries that need them most, while developing countries do not have the resources to stem the flow or even replace those lost. Postmodern philosopher Emmanuel Levinas offers a unique ethical framework that is helpful in assessing both the irresponsibility inherent in the current global health care situation and the responsibility and obligation held by the stakeholders involved in this global crisis. Drawing on Levinas' exploration of individual freedom and self-pursuit, infinite responsibility for the Other, and the potential emergence of a just community, we demonstrate its effectiveness in explaining the health care worker crisis, and we argue in favor of a variety of policy and development assistance measures that are grounded in an orientation of non-indifference toward Others.

Pilot-Wave Hydrodynamics

NASA Astrophysics Data System (ADS)

Bush, John W. M.

2015-01-01

Yves Couder, Emmanuel Fort, and coworkers recently discovered that a millimetric droplet sustained on the surface of a vibrating fluid bath may self-propel through a resonant interaction with its own wave field. This article reviews experimental evidence indicating that the walking droplets exhibit certain features previously thought to be exclusive to the microscopic, quantum realm. It then reviews theoretical descriptions of this hydrodynamic pilot-wave system that yield insight into the origins of its quantum-like behavior. Quantization arises from the dynamic constraint imposed on the droplet by its pilot-wave field, and multimodal statistics appear to be a feature of chaotic pilot-wave dynamics. I attempt to assess the potential and limitations of this hydrodynamic system as a quantum analog. This fluid system is compared to quantum pilot-wave theories, shown to be markedly different from Bohmian mechanics and more closely related to de Broglie's original conception of quantum dynamics, his double-solution theory, and its relatively recent extensions through researchers in stochastic electrodynamics.

Diffraction and interference of walking drops

NASA Astrophysics Data System (ADS)

Pucci, Giuseppe; Harris, Daniel M.; Bush, John W. M.

2016-11-01

A decade ago, Yves Couder and Emmanuel Fort discovered a wave-particle association on the macroscopic scale: a drop can bounce indefinitely on a vibrating bath of the same liquid and can be piloted by the waves that it generates. These walking droplets have been shown to exhibit several quantum-like features, including single-particle diffraction and interference. Recently, the original diffraction and interference experiments of Couder and Fort have been revisited and contested. We have revisited this system using an improved experimental set-up, and observed a strong dependence of the behavior on system parameters, including drop size and vibrational forcing. In both the single- and the double-slit geometries, the diffraction pattern is dominated by the interaction of the walking droplet with a planar boundary. Critically, in the double-slit geometry, the walking droplet is influenced by both slits by virtue of its spatially extended wave field. NSF support via CMMI-1333242.

[The three lives of the Count de Bonneval, alias Osman Pasha (1675-1747)].

PubMed

Fabre, André-Julien

2008-12-01

Count Claude-Alexandre de Bonneval (1675-1747), had a unusual existence: he had three consecutive lives: as an Officer in the Royal Guard of Louis XIV, as Major-General with Prince Emmanuel of Savoy and, finally, as Ottoman Pasha in Constantinople. He was a man of multiple facets: soldier and political adviser, swordsman and world traveller, friend of Casanova, Fenelon, Montesquieu and Leibniz. He was also an inveterate transgressor of every rule and, in the end, a renegade apostate. Many explanations have been offered for his astounding life: plain aristocratic frivolity, emotional instability, and possibly, in reference to a permanent quest for new adventures, countries or religions, a touch of transformism. Obviously, Bonneval concealed, behind a flamboyant personality, some sort of psychiatric fragility which might suggest, in retrospect, a "paranoid syndrome" but, certainly, no trace of what is common in psychopathic patients, a weariness of life. Bonneval loved each one of his three lives and the feeling was mutual.

Unavowed Abstention Can Overturn Poll Predictions

Galam, Serge

2018-03-01

I revisit the 2017 French Presidential election which opposed the far right National Front candidate Marine Le Pen against the center candidate Emmanuel Macron. While voting intentions for Le Pen stuck below 50% and polls kept predicting her failure, I warned on the emergence of a novel phenomenon I defined as unavowed abstention, which could suddenly reverse the ranking at Le Pen benefit on the voting day. My warning got a massive media coverage. She eventually lost the runoff at a score worse than predicted by the polls. Using a quantitative mathematical framing, which reveals the existence of tipping points in respective turnouts, I show that the predicted phenomenon of unavowed abstention did happen. But instead of shattering the expected outcome, against all odds it occurred at Le Pen expense, therefore without impact on the final outcome. The results shed a new light on other national cases such as Obama and Trump victories in the US.

[Health services, morbidity and mortality in the regiment of the Papal Zouaves in Italy (1861-1870)].

PubMed

Guenel, J

1995-01-01

The regiment of the Zouaves pontificaux was formed by young Catholic volunteers, chiefly French, Dutch and Belgian, who enrolled for the defence of the Pontifical State from 1861 to 1870 against the scheme of the United Italy planned by King Victor-Emmanuel II and Garibaldi. For ten years fights were scarce. They only took place in 1867 principally in Mentana and in September 1870 when the papal state was invaded and Rome taken. At first the military medical service in the regiment as in the whole army was rather inadequate except for the central hospital. The ambulances system was based largely upon benevolent people. But the organization improved in 1870. On the whole amongst more than 9,000 enlisted volunteers, 476 died (5%). The causes of death were more often diseases (78%) than injuries. As in all the armies of that time, cholera, smallpox, typhoid fever made a lot of victims. Malaria which still reigned in the Latium was responsible of a large morbidity.

Levinas and the Hippocratic oath: a discussion of physician-assisted suicide.

PubMed

Degnin, F D

1997-04-01

At least from the standpoint of contemporary cultural and ethical resources, physicians have argued eloquently and exhaustively both for and against physician-assisted suicide. If one avoids the temptation to ruthlessly simplify either position to immorality or error, then a strange dilemma arises. How is it that well educated and intelligent physicians, committed strongly and compassionately to the care of their patients, argue adamantly for opposing positions? Thus rather than simply rehashing old arguments, this essay attempts to rethink the nature of human morality as both a source and a fracturing of human rationality- and with morality, the question of human nature in the context of violence, oppression, service, and obligation. This interpretation of moral life is laid out roughly along the lines of the Jewish philosopher Emmanuel Levinas, and further clarified through a discussion of the Hippocratic Oath. These resources are then brought to bear on the specific arguments and recommendations concerning physician-assisted suicide.

Manipur and Nagaland in northeast India report an antenatal HIV prevalence of > 1% and the current HIV prevalence among injecting drug users is 24% and 4.5% respectively. Through support from DFID's Challenge Fund, Emmanuel Hospital Association (EHA) established thirteen drop-in-centres across the two states to deliver opioid substitution treatment with sublingual buprenorphine for 1200 injecting drug users. Within a short span of time the treatment has been found to be attractive to the clients and currently 1248 injecting opioid users are receiving opioid substitution treatment. The project is acceptable to the drug users, the families, the communities, religious as well as the militant groups. The treatment centres operate all days of the week, have trained staff members, utilize standardized protocols and ensure a strict supervised delivery system to prevent illicit diversion of buprenorphine. The drug users receiving the substitution treatment are referred to HIV voluntary counselling and testing. As this treatment has the potential to change HIV related risk behaviours, what has been established in the two states needs to be continued and expanded with the support from the Government of India.

Abbadia: un étonnant château-observatoire

NASA Astrophysics Data System (ADS)

Briot, Danielle

2016-09-01

The observatory-castle Abbadia is standing in Hendaye, in the French Basque Country, in the South-West of France. The man who planned this building was Antoine d'Abbadie, both an explorer and a scientist. After spending several years in Abbissinia, now Ethiopia, he came back at home and he wanted to build a large house, actually a castle, which was also a scientific place containing an observatory. The very famous architects of the castle were Eugène-Emmanuel Viollet-le-Duc and his assistant Edmond Duthoit. The style is neogothic as typical of the nineteenth century. The main instrument of the observatory is a meridian refracting telescope made in 1879 by Eichens. The meridian circle is graduated in grades, that is a decimal angle unit established during the French Révolution. Similarly, the time unit of clocks are decimal units. The meridian observations of stars were carried on after the death of Antoine d'Abbadie in 1901, during three quarters of a century and observations of more than 50000 stars were published. Nowadays the castle is open to the public and pupils, and the scientific instruments have been put in use again.

What Does the Patient Say? Levinas and Medical Ethics.

PubMed

Burns, Lawrence

2017-04-01

The patient-physician relationship is of primary importance for medical ethics, but it also teaches broader lessons about ethics generally. This is particularly true for the philosopher Emmanuel Levinas whose ethics is grounded in the other who "faces" the subject and whose suffering provokes responsibility. Given the pragmatic, situational character of Levinasian ethics, the "face of the other" may be elucidated by an analogy with the "face of the patient." To do so, I draw on examples from Martin Winckler's fictional physician narratives. In addition, I explore how the standpoint of the physician conceals a related but often unacknowledged dimension of care: the obligation to nurse. For both nurse and physician, one question encapsulates Levinas' medical ethics: "What does the patient say?" Using this as my guiding question, I examine the context within which physician, nurse, and patient meet in order to highlight their shared vulnerability and the care relationship that binds them together. © The Author 2017.

Global nature of Pc 5 magnetic pulsation during the WHI observation campaign

NASA Astrophysics Data System (ADS)

Fujimoto, A.; Tokunaga, T.; Abe, S.; Uozumi, T.; Yoshikawa, A.; Yumoto, K.; Group, M.

2008-12-01

In conjunction with the activities of IHY(International Heliophysical Year), an international observation campaign was planned and carried out from March 20 to April 16 of 2008. The name of this campaign is Whole Heliosphere Interval (WHI). During WHI, the nations of the world worked together to collect relevant scientific data. As a result, there now exists an exceptionally good data set of multi-point ground-based and satellite magnetometer data for this time frame. There were no clear and outstanding geomagnetic storms during WHI, but there were some moderate geomagnetically active moments. For example, on March 26, Dst index decreased from 25 nT to -41 nT for 10 hours(1000 -1900 UT). The amplitude of Pc 5 pulsation in the frequency band between 1.67 and 6.67 mHz at the MAGDAS stations increased for few days after March 26. Using magnetometer data obtained globally from ULTIMA(Ultra Large Terrestrial International Magnetic Array) stations, we will investigate the occurrence and wave characteristics(amplitude, period and phase) of Pc 5 pulsations. Particularly high-latitude Pc 5 observed at THEMIS (the Time History of Events and Macroscopic Interactions during Substorms), CARISMA(Canadian Array for Realtime Investigations of Magnetic Activity) and McMaC (Mid-continent Magnetoseismic Chain) stations will be compared with equatorial-latitude Pc 5 observed at MAGDAS stations(TIR, DAV, YAP, ANC, EUS, ILR, and UT=LT+5h, +8h, +9h, -5h, -2h and 0h, respectively). Acknowledgment: MAGDAS data used in this paper were obtained in mutual collaborations with the following representatives of various organizations; Prof. Archana Bhattacharya(Indian Institute of Geomagnetism, TIR), Fr.

Reflections on social justice, race, ethnicity and identity from an ethical perspective

NASA Astrophysics Data System (ADS)

Atweh, Bill

2011-03-01

In these reflections, I identify complexities in few constructs that are often used in educational research, although not often critically, namely, social justice, race, ethnicity and identity. This paper suggests a non-ontological and non-epistemological approach to ethics as developed by Emmanuel Levinas as a normative means to deal with some of the complexities. In dealing with the construct of social justice, an ethical approach calls for productive research tools to not only understand exclusion but also to change situations of injustice to marginalised groups. Further, both constructs race and ethnicity can be used to identify groups of people based on their history, culture and/or lifestyles. As social constructions they have different historical origins and are open to alternative connotations, uses and abuses. An ethical perspective is useful to manage the dilemma of essentialism that group identification may lead into. Finally, the debate around the usefulness of the construct of identity raises some ethical questions about the role of research and the lived experience of its subjects. An ethical stance demands that constructs of analysis in social inquiry should not only demonstrate their utility for knowledge generation but also should demonstrate a responsibility for the construction and reconstruction of lifeworld in which academic endeavours are conducted.

2011-11-01

This is a discussion of the article "Brief Interventions With Parents, Infants, and Young Children: A Framework for Thinking by Louise Emmanuel." Questions of symptom formation, the difference between a defense and developmental phenomena, and different therapeutic techniques are explored from the perspective of The Baby as Subject (an infant-parent psychotherapy approach developed at the Royal Children's Hospital in Melbourne, Australia). The relationship between feeding difficulties and the dynamics of the infant-parent attachment relationship are discussed with reference to whether the infant's apparent self-sufficiency is interpersonally generated and whether bids for autonomy are a sign of healthy, age-appropriate developmental drives at play. The use of representational toys in infant-parent psychotherapy to enable infants and toddlers to represent their experience or for the therapist to visually express what he or she understands the infant's experience to be and thus to work directly with the infant's representations is outlined. In addition to the linguistic content of verbal interpretations, the infant is receptive to the experience of another thinking mind and the emotional language, facial expressions, and gestures that also convey to the baby the experience of being understood or misunderstood.

Toward an asymptotic behaviour of the ABC dynamo

NASA Astrophysics Data System (ADS)

Bouya, Ismaël; Dormy, Emmanuel

2015-04-01

The ABC flow was originally introduced by Arnol'd to investigate Lagrangian chaos. It soon became the prototype example to illustrate magnetic-field amplification via fast dynamo action, i.e. dynamo action exhibiting magnetic-field amplification on a typical timescale independent of the electrical resistivity of the medium. Even though this flow is the most classical example for this important class of dynamos (with application to large-scale astrophysical objects), it was recently pointed out (Bouya Ismaël and Dormy Emmanuel, Phys. Fluids, 25 (2013) 037103) that the fast dynamo nature of this flow was unclear, as the growth rate still depended on the magnetic Reynolds number at the largest values available so far (\\text{Rm} = 25000) . Using state-of-the-art high-performance computing, we present high-resolution simulations (up to 40963) and extend the value of \\text{Rm} up to 5\\cdot105 . Interestingly, even at these huge values, the growth rate of the leading eigenmode still depends on the controlling parameter and an asymptotic regime is not reached yet. We show that the maximum growth rate is a decreasing function of \\text{Rm} for the largest values of \\text{Rm} we could achieve (as anticipated in the above-mentioned paper). Slowly damped oscillations might indicate either a new mode crossing or that the system is approaching the limit of an essential spectrum.

Diagnosis of narcolepsy and idiopathic hypersomnia. An update based on the International classification of sleep disorders, 2nd edition.

2007-10-01

Defining the precise nosological limits of narcolepsy and idiopathic hypersomnia is an ongoing process dating back to the first description of the two conditions. The most recent step forward has been done within the preparation of the second edition of the "International classification of sleep disorders" published in June 2005. Appointed by Dr Emmanuel Mignot, the Task Force on "Hypersomnias of central origin, not due to a circadian rhythm sleep disorder, sleep related breathing disorder, or other causes of disturbed nocturnal sleep" thoroughly revisited the nosology of narcolepsy and of idiopathic hypersomnia. Narcolepsy is now distinguished into three different entities, narcolepsy with cataplexy, narcolepsy without cataplexy and narcolepsy due to medical condition, and idiopathic hypersomnia into two entities, idiopathic hypersomnia with long sleep time and idiopathic hypersomnia without long sleep time. Nevertheless there are still a number of pending issues. What are the limits of narcolepsy without cataplexy? Is there a continuum in the pathophysiology of narcolepsy with and without cataplexy? Should sporadic and familial forms of narcolepsy with cataplexy appear as subgroups in the classification? Are idiopathic hypersomnia with long sleep time and idiopathic hypersomnia without long sleep time, two forms of the same condition or two different conditions? Is there a pathophysiological relationship between narcolepsy without cataplexy and idiopathic hypersomnia without long sleep time?

Results from the Phoenix Urban Heat Island (UHI) experiment: effects at the local, neighbourhood and urban scales

This paper reports on the analysis of results from a large urban heat island experiment (UHI) performed in Phoenix (AZ) in April 2008. From 1960 to 2000, the city of Phoenix experienced a minimum temperature rise of 0.47 °C per decade, which is one of the highest rates in the world for a city of this size (Golden, 2004). Contemporaneously, the city has recorded a rapid enlargement and large portion of the land and desert vegetation have been replaced by buildings, asphalt and concrete (Brazel et al., 2007, Emmanuel and Fernando, 2007). Besides, model predictions show that minimum air temperatures for Phoenix metropolitan area in future years might be even higher than 38 °C. In order to make general statements and mitigation strategies of the UHI phenomenon in Phoenix and other cities in hot arid climates, a one-day intensive experiment was conducted on the 4th-5th April 2008 to collect surface and ambient temperatures within various landscapes in Central Phoenix. Inter alia, infrared thermography (IRT) was used for UHI mapping. The aim was to investigate UHI modifications within the city of Phoenix at three spatial scales i.e. the local (Central Business District, CBD), the neighborhood and the city scales. This was achieved by combining IRT measurements taken at ground level by mobile equipment (automobile-mounted and pedicab) and at high elevation by a helicopter. At local scale detailed thermographic images of about twenty building façades and several street canyons were collected. In total, about two thousand images were taken during the 24-hour campaign. Image analysis provides detailed information on building surface and pavement temperatures at fine resolution (Hedquist et al. 2009, Di Sabatino et al. 2009). This unique dataset allows us several investigations on local air temperature dependence on albedo, building thermal inertia, building shape and orientation and sky view factors. Besides, the mosaic of building façade temperatures are being analyzed

Influence of structure on radiation shielding effectiveness of graphite fiber reinforced polyethylene composite

NASA Astrophysics Data System (ADS)

Emmanuel, A.; Raghavan, J.

2015-10-01

While LEO and GEO are used for most satellite missions, Highly Elliptical Orbits (HEOs) are also used for satellite missions covering Polar Regions of Earth. Satellites in HEO are exposed to a relatively harsher radiation environment than LEO and GEO. The mass of traditionally used aluminum radiation shield, required to attenuate the radiation to a level below a certain threshold that is safe for the satellite bus and payload, scales with the level of radiation. It has been shown (Emmanuel et al., 2014) that materials with low atomic number (Z) such as polyethylene (PE) can result in a lighter shield than aluminum (Al) in HEO. However, PE has to be reinforced with relatively high Z fibers such as graphite (G) to improve its mechanical properties. The effect of introduction of G and the resulting composite structure (that meets the requirements on mechanical properties, manufacturing and service) on the radiation shielding effectiveness of PE was studied through simulation using a layered PE-G composite. The Total Ionization Dose (TID), deposited in a silicon detector behind the composite shield, has been found to be function of layer volume fraction, layer thickness and stacking sequence of the PE and G layers. One composite configuration has resulted in a TID lower than that for PE, demonstrating the possibility of tailoring the mechanical properties of PE-based composite radiation shield with minimal negative impact on its radiation shielding effectiveness.

Palliative care has not developed widely in rural North India. Since 2010, the Emmanuel Hospitals Association (EHA) has been developing a model of palliative care appropriate for this setting, based on teams undertaking home visits with the backup of outpatient and inpatient services. A project to further develop the model operated from 2012 to 2015 supported by funding from the UK. This study aims to evaluate the EHA palliative care project. Rapid evaluation method using a mixed method realist approach at the five project hospital sites. An overview of the project was obtained by analyzing project documents and key informant interviews. Questionnaire data from each hospital were collected, followed by interviews with staff, patients, and relatives and observations of home visits and other activities at each site. Descriptive analysis of quantitative and thematic analysis of qualitative data was undertaken. Each site was measured against the Indian Minimum Standards Tool for Palliative Care (IMSTPC). Each team followed the EHA model, with local modifications. Services were nurse led with medical support. Eighty percent of patients had cancer. Staff demonstrated good palliative care skills and patients and families appreciated the care. Most essential IMSTPC markers were achieved but morphine licenses were available to only two teams. Remarkable synergy was emerging between palliative care and community health. Hospitals planned to fund palliative care through income from surgical services. Excellent palliative care appropriate for rural north India is delivered through the EHA model. It could be extended to other similar sites.

Sensitivity experiments of a regional climate model to the different convective schemes over Central Africa

NASA Astrophysics Data System (ADS)

Armand J, K. M.

2017-12-01

In this study, version 4 of the regional climate model (RegCM4) is used to perform 6 years simulation including one year for spin-up (from January 2001 to December 2006) over Central Africa using four convective schemes: The Emmanuel scheme (MIT), the Grell scheme with Arakawa-Schulbert closure assumption (GAS), the Grell scheme with Fritsch-Chappell closure assumption (GFC) and the Anthes-Kuo scheme (Kuo). We have investigated the ability of the model to simulate precipitation, surface temperature, wind and aerosols optical depth. Emphasis in the model results were made in December-January-February (DJF) and July-August-September (JAS) periods. Two subregions have been identified for more specific analysis namely: zone 1 which corresponds to the sahel region mainly classified as desert and steppe and zone 2 which is a region spanning the tropical rain forest and is characterised by a bimodal rain regime. We found that regardless of periods or simulated parameters, MIT scheme generally has a tendency to overestimate. The GAS scheme is more suitable in simulating the aforementioned parameters, as well as the diurnal cycle of precipitations everywhere over the study domain irrespective of the season. In JAS, model results are similar in the representation of regional wind circulation. Apart from the MIT scheme, all the convective schemes give the same trends in aerosols optical depth simulations. Additional experiment reveals that the use of BATS instead of Zeng scheme to calculate ocean flux appears to improve the quality of the model simulations.

Integrating the progress that has been made on a daily basis since it was jointly commissioned in 2013 by the French National Academy of Medicine (Biotechnology Committee XX, Prof Emmanuel-Alain Cabanis) and the Technologies Academy (Pr Jean de Kervasdoué), this report, covering such a vast subject, can only represent one step in a long process. Summarized here in a volume compatible with the Bulletin, it makes reference to the full report (52 pages ; 22 pages of text, 4 pages of references, a 20-page glossary for physicians, plus 522 figures spanning 6 pages), which is available on the Academy's website. The six chapters first define "health" (WHO) and "informatics" and provide a brief history. The first chapter, on technologies, is divided into "bad" news (cybercrime, ecological risks) and advances relevant to health. The next four chapters describe the contribution of digitization to patient management, ranging from "fragile" individuals (from the gamete to old age and dependency) to healthy subjects trained to work in hostile situations (scuba diving to space exploration), and finally research. The last chapter proposes 7 areas for progress: expansion of the national imaging and communications platforms, stimulation of the medical robotics industry, extension of telemedicine to all medical and surgical specialties, support for drug dispensing and therapeutic education, and foundation of a European portal for m-health certification, research prioritization according to multiyear health plans, and reinforcement of mathematic education, starting in primary school (see: "La main à la pâte" ("Going hands-on").

Ask me what is in my heart of hearts! The core question of care in relation to parents who are patients in a psychiatric care context.

PubMed

Blegen, Nina Elisabeth; Eriksson, Katie; Bondas, Terese

2016-01-01

The aim is to understand the experience of being cared for in psychiatric care as a patient and as a parent. Parenthood represents the natural form of human caring, a human directedness regardless of gender. The study has its starting point in this image, as it applies to mothers who receive care as provided in a psychiatric care context. The theoretical perspective is the theory of caritative caring, and the methodological approach is the philosophical hermeneutics outlined by Gadamer. The sample was purposeful: 10 mothers who experienced being a mother while suffering from mental illness and receiving care from professionals in psychiatric specialist health care contexts. The interpretation process is inductive, deductive, and abductive, and includes different levels of rational, contextual, existential, and ontological interpretation supported by the chosen theoretical perspective and the philosophy of ethics outlined by Emmanuel Levinas. The interpretation on the contextual level shows that the patients do not talk about their inner feelings concerning themselves as mothers in the care relationship. The interpretation on the existential level reveals the meaning of the mothers' experiences of inner struggle between their inner demands and assuming a mask of silence. The patients' experiences on the ontological level were interpreted as a struggle between the responsibility inherent in human being and the fear of condemnation. At the ontological level, a new hypothesis of the understanding of the meaning of the parents' experiences was formulated: Being in care as a patient and as a parent means struggling to restore one's responsibility as a human being. This new understanding paves the way for caring of the patient who is a parent.

Moral instability: the upsides for nursing practice.

PubMed

McCarthy, Joan

2010-04-01

This article briefly outlines some of the key problems with the way in which the moral realm has traditionally been understood and analysed. I propose two alternative views of what is morally interesting and applicable to nursing practice and I indicate that instability has its upsides. I begin with a moral tale - a 'Good Samaritan' story - which raises fairly usual questions about the nature of morality but also the more philosophically fundamental question about the relationship between subjectivity and moral agency. I then consider this relationship from the perspectives of two twentieth century philosophers: Emmanuel Levinas and Michel Foucault. Levinas' basic point is that the experience of ethical subjectivity is made possible through others: the demand to respond to the existence of others is the basic social structure that precedes individual freedom. If Levinas posits intersubjectivity as a fundamental or primitive feature of the moral realm, Foucault poses an even more basic question: how have moral subjects and relations of obligation been constituted? The aim of ethical inquiry, for Foucault, is to describe the network of discourses, institutions, relations, and practices through which certain kinds of subjects are constituted and constitute themselves, e.g. as a kind of person who can act morally. Finally, I consider some recent research in philosophy of nursing which illustrates how Levinasian and/or Foucauldian perspectives can deepen understanding of nurses' moral practices, specifically, the work of Norwegian public health nurses, Canadian pediatric nurses, and Irish midwives. I suggest that in spite of the instability of morality in general and the particular ethical challenges that face nurses, there are grounds for hope and possible strategies for living in unstable times.

Another condom uproar in Uganda.

Musoke, D

A campaign to promote safe sex through the use of condoms has sparked a heated controversy in Uganda, as influential religious leaders have come out in opposition to a practice which they fear will lead to sexual promiscuity. The campaign, backed by the Ugandan government, is designed to halt the rapidly spreading AIDS epidemic. With 20,000 AIDS cases as of June 1991, Uganda leads all African countries in the number of reported cases. Additionally, it is estimated that some 7 million of the country's 17 million inhabitants are HIV-positive. This alarming situation forced President Yoweri Museveni to reverse his stance and come out in favor of the condom campaign. The campaign is being launched by the Ugandan pharmaceutical firm Armtrades Ltd with financial and technical support from USAID and the Ugandan government. The condom campaign, however, has aroused strong opposition from the religious community. Angered by advertisements advising Ugandans to "love carefully" by wearing condoms, Catholic Archbishop Emmanuel Wamala urged his followers in August to reject condoms, calling then an insult to the dignity of man. Following Wamala's lead, other top churchmen came out in opposition to the condom campaign at a recent AIDS prevention leadership conference. One of the clergymen present at the conference told Health Minister James Makumbi that the condom campaign will make young people indulge in uncontrolled sexual immorality. Moslem clerics have also stated their opposition to condoms, fearing sexual promiscuity. But the religious community itself has come under criticism for their opposition to condoms. Stressing that lives are at stake, the popular weekly Topic recently cautioned churchmen that this is not the time to engage in academic and moralistic debates.

Development of Ensemble Model Based Water Demand Forecasting Model

In recent years, Smart Water Grid (SWG) concept has globally emerged over the last decade and also gained significant recognition in South Korea. Especially, there has been growing interest in water demand forecast and optimal pump operation and this has led to various studies regarding energy saving and improvement of water supply reliability. Existing water demand forecasting models are categorized into two groups in view of modeling and predicting their behavior in time series. One is to consider embedded patterns such as seasonality, periodicity and trends, and the other one is an autoregressive model that is using short memory Markovian processes (Emmanuel et al., 2012). The main disadvantage of the abovementioned model is that there is a limit to predictability of water demands of about sub-daily scale because the system is nonlinear. In this regard, this study aims to develop a nonlinear ensemble model for hourly water demand forecasting which allow us to estimate uncertainties across different model classes. The proposed model is consist of two parts. One is a multi-model scheme that is based on combination of independent prediction model. The other one is a cross validation scheme named Bagging approach introduced by Brieman (1996) to derive weighting factors corresponding to individual models. Individual forecasting models that used in this study are linear regression analysis model, polynomial regression, multivariate adaptive regression splines(MARS), SVM(support vector machine). The concepts are demonstrated through application to observed from water plant at several locations in the South Korea. Keywords: water demand, non-linear model, the ensemble forecasting model, uncertainty.

Dacryocystitis usually results from blockage of the nasolacrimal duct. The treatment of such obstruction is surgery. There is a fivefold risk of soft tissue infection after open lacrimal surgery without systemic antibiotic prophylaxis that represents a significant risk of failure in lacrimal surgery. To determine the current bacteriology of dacryocystitis and their sensitivity to different antibiotics at Menelik II Hospital. Consecutive patients with dacryocystitis who presented to the department of ophthalmology at Menelik II Hospital between May 2004 and September 2005 were included in the study. Each patient was sent for culture and sensitivity test. Culture and sensitivity tests were obtained from Ethiopian National Health Research Institute (ENHRI), Arsho, Black Lion and Emmanuel Higher clinic laboratories. One hundred fourteen patients, 58 (50.9%) males and 56 (49.1%) females, with dacryocystitis were examined The majority of cases, 82 (71.9%), were under 30 years of age. Positive results were obtained from 91 (79.8%) patients. Gram-positive and gram negative organisms were isolated from 57 (62.6%) and 34 (37.4%) samples respectively. The five most common isolates were Streptococcus pneumoniae (23%), Streptococcus pyogens (14.3%), Staphylococcus aureus (12.1%), Streptococcus viridans (9.9%) and Haemophilus influenzae (9.9%). The antibiotics to which the majority of the isolates sensitive to were chloramphenicol (82.4%), gentamycin (79.1%), erythromycin (68.1%) and tetracycline (61.5%). While Streptococcus pneumoniae was sensitive to chloramphenicol in 95.2%. its sensitivity to tetracycline was 100%. Haemophilus influenzae was sensitive to tetracycline and chloramphenicol in 88.9% and 77.8% respectively. Gram positive organisms were the most common causes of dacryocystitis. Streptococcus pneumoniae and Haemophilus Influenza was the commonest gram positive and gram negative organisms identified respectively. Chloramphenicol and tetracycline were effective

Alienation and alterity: Age in the existentialist discourse on others.

PubMed

Zimmermann, Harm-Peer

2016-12-01

Aging Studies and Postcolonial Studies belong together in a rather fundamental way, given that they share profound theoretical roots and far-reaching critical perspectives. These derive not only from the more recent poststructuralist discourse on others but also, further back, from the existentialist discourse on others - particularly in issues relating to "The Look" as elaborated by Jean-Paul Sartre in his major philosophical treatise Being and Nothingness and in his reflections on racism, colonialism and humanism. These texts have had a decisive influence on both Aging Studies and Postcolonial Studies. First, no less a figure than one of the main progenitors of Postcolonial Studies, Frantz Fanon, drawing on Sartre, analyses the gaze of the colonial masters and black responses. Second, two of the most significant theoretical works on aging and age to have appeared since 1945 were directly inspired by Sartre: Jean Améry's On Aging and Simone de Beauvoir's The Coming of Age. Additional sources of interest are the phenomenology of responsibility by Emmanuel Lévinas and works on absurdity and rebellion by Albert Camus. It is this early influence that is explored from two perspectives adopted by more recent postcolonialist discourse: debates around the concept of alienation involve analysing and critiquing the kind of epistemic violence which renders abject and invisible not only old people but also all those who are 'othered' by a dominant gaze (racism, ageism, othering); and the concept of alterity involves debating ways of acknowledging otherness responsibly on the one hand and being able to articulate and represent oneself on the other: Can the subaltern speak? We might similarly ask "Can the old speak?" Postcolonial discourse tells us that this is not quite as easy as some versions of so-called "Happy Gerontology" proclaim. The aim of the present article is to examine the foundational existentialist critique of racism and ageism and to render it useful for re

[Aspects of phenomenal philosophy as starting point for a new animal-human relationship

PubMed

Brenner, Andreas

1998-01-01

The legally legitimised relationship to animals mirrors the history of philosophy. The relationship between animals and people in the Middle Ages and in the early Modern Age and the then corresponding jurisdiction allows great insights in this respect. Animals were then considered equal to people. As a consequence, it was possible in the Middle Ages and in the early Modern Age that legal proceedings against animals were undertaken, animals could even be sentenced to death. Enlightenment philosophy changed this by giving legal status exclusively to humans. In modernity animals are not considered to be people. Animals do not act voluntarily and do not have conscious knowledge of possible reactions to their own actions. Because of that, it is not possible to hold them responsible for their actions. The philosophically based premises for guilt are not given and therefore legal proceedings against animals are no longer justified. The law in respect to animals underwent complete changes as a consequence of philosophical innovation. Legally, animals are now objects and fall under the law of property. The depersonalisation of animals and accordingly the withdrawal of rights that are now exclusively given to people turns animals into basic commodities. The current efforts in philosophy to restore the respect for animals are answered either with the concept of interest or again with a concept that is linked to personality. Both ways turn out to be inadequate when it comes to integrating animals into ethics. Therefore we suggest an ethics that is open to empathy and the "view of the other". The supported ethics is orientated to the phenomenal philosophy of Emmanuel Lévinas and in contrast to conventional types of ethics it represents a higher degree of coherence as the phenomenal ethics is able to integrate phenomena of life as much as possible. Phenomenal ethics gives reasons for a title of life for higher animals and the prohibition of animal testing. The banning of animal

Use of medium-range weather forecasts for drought mitigation and adaptation under a Mediterranean area Authors: Ouiam Lahlou1, Yasmina Imani1, Si Bennasser Alaoui1, Emmanuel Dutra 2, Francesca Di Guiseppe2, Florian Pappenberger2, Fredrik Wetterhall2 1: Institut Agronomique et Vétérinaire Hassan II (IAV Hassan II) 2: European Center for Medium-Range Weather Forecasts (ECMWF) The main pillar of economic development in Morocco is the agricultural sector employing 40% of the active workforce. Agriculture is still mainly dominated by rainfed agriculture which is vulnerable to an increasing frequency and severity of drought events. In rainfed agriculture, there are few interventions possible once crops are planted. Medium to long range weather forecasts could therefore provide valid information for crop selection and sowing time at the onset of the yield season and later to plan mitigation measures during dry-spell episodes. More than 600 daily forecasts from the European Centre for Medium-Range Weather Forecasts (ECMWF) ensemble forecasting system were analyzed in terms of probabilistic skills scores. Results show that, while daily and weekly accumulated precipitation are poorly predicted there is good skill in the forecast of occurrence and extent of dry periods. The availability of this information to decision makers in the agricultural sector would mean moving from a reactive drought management plan to a proactive one. This is very important, especially for the remote areas where often the needed help comes late. A simulation case-study involving farmers who were made aware of the availability of forecasts for the next seasons, show that medium-range forecasts will allow i) governments and relief agencies to position themselves for more effective and cost-efficient drought interventions, ii) producers to be more aware of their production options and insure their payment rate, iii) Herders, to cope with higher food costs for their cattle iv) farmers to better plan

Geomorphosites and the history of geomorphology

NASA Astrophysics Data System (ADS)

Giusti, Christian

2013-04-01

Geomorphosites are geosites of geomorphological significance, with a now well admitted distinction between central or scientific values on the one hand, and additional values such as ecological, economical or aesthetical values on the other hand. Among the scientific values, some are directly linked to the climatic forcings through geomorphological processes in the case of active geomorphosites, for example the meaning of a waterfall in a post-glacial trough valley. In the case of passive geomorphosites, the central values rather lie in structural features, ancient landforms, inherited regoliths such as the clay-with-flints of the Chalklands of Southern England and Northern France. Sometimes, the scientific value is not fully determined by the type of geomorphosite, active or passive, but rather by the fact this geosite has a special importance concerning the history of the Earth sciences, especially in geomorphology. This is well exemplified with the famous case of the Nant d'Arpenaz waterfall S-folds in the lower Arve valley between Geneva and Chamonix, first described by Horace Benedict de Saussure in 1774 and invoked to explain the formation of the Alps by folding. This structural geosite (history of tectonics) is also a geomorphosite. Concerning geomorphology, the current Nant d'Arpenaz waterfall is quite similar to the Pissevache waterfall in the Rhone valley: they are both examples of postglacial geomorphosites due to hanging valleys. When erosion is more advanced narrow gorges appear, for example Diosaz gorge (Haute-Savoie, France) or Dailley, Trient and Triège gorges (Valais, Switzerland). All these geomorphosites (main trough valleys, tributary valleys, waterfalls and postglacial gorges) were studied by pionneers of fluvial and glacial geomorphology such as Jean Bruhnes and Emmanuel de Martonne before World War I. The former has played an important role at the University of Fribourg (Switzerland) and has devoted many studies about the potholes and eddies

No statistically significant association was found between digital health use and self-rated general and mental health status. Concerning opinions on digital health, although 94.1% (475/505) of students estimated that today's digital health cannot replace traditional health services and medical consultations, 44.6% (207/464) of students declared that this could be possible in the future, provided that digital health interventions are promoted by institutional or official entities.

Sedimentary records allow us to establish a link between two major landslides affecting the flanks of Piton de la Fournaise volcano and the triggering of major turbidity currents. Thus, the age of these events could be obtained; their chronology being far too difficult to establish otherwise. In short: a beautiful example of the contribution of sedimentology to the study of the structural evolution of the volcanoes.

Inspection of probe reactions of disputed mutations may potentially resolve discordance between genotypic and phenotypic test results. We propose a novel approach for potential real-time detection of RR-TB transmission through fully using digitally linked TB diagnostics and shared repository of test results. To our knowledge, this is the first pragmatic and scalable work in response to the consensus of world-renowned TB experts in 2016 on the potential of diagnostic connectivity to accelerate efforts to eliminate TB. This is evidenced by the ability of our proposed approach to facilitate comparison of probe reactions between different RDTs used in the same setting. Integrating this proposed approach as a plug-in module to a connectivity platform will increase usefulness of connected TB diagnostics for RR-TB outbreak detection through real-time investigation of suspected RR-TB transmission cases based on epidemiologic linking. ©Kamela Charmaine Ng, Conor Joseph Meehan, Gabriela Torrea, Léonie Goeminne, Maren Diels, Leen Rigouts, Bouke Catherine de Jong, Emmanuel André.

In its current form, the Département de psychiatrie at the Université de Montréal (UdeM) was created in 1964. The first person to have headed was Dr. Gerard Beaudoin… Between 1948 and 1964, several others psychiatrists were heading the Département without necessary bearing a particular title.The directors of the Département from 1951 to now were: Drs. Fernand Côté, Camille Laurin, Gerard Beaudoin, Yvon Gauthier, Arthur Amyot, Francis Borgeat, Hugues Cormier, Sylvain Palardy, Jean Hébert, and Emmanuel Stip.When the Département opened, it was the second institution in Montréal that was training psychiatrists. During the first year, there were 3 psychiatric residents, but within 20 years this number had increased to 63. From the early years, teaching psychiatry to residents, and subsequently to all UdeM medical students, has been a priority in the Département, and over the years many psychiatrists trained at UdeM have attained leadership positions elsewhere. The Département attained an early reputation for excellence in both clinical and basic research.The strengths the Département developed in its early years in clinical psychopharmacology, in basic research in neurotransmitters, sleep, cognition, forensic, and in community psychiatry have been augmented more recently with active programs in psychotherapy research, substance abuse research, psychoneuroendocrinology, developmental aspects of behavior, genetics, epigenetics as well as the study of the brain through a variety of brain scanning techniques.The history of the Département de psychiatrie de l'Université de Montréal is largely dependent on that of each of the institutions affiliated to the Université: the Pavillon Albert-Prévost de l'Hôpital du Sacré-Coeur de Montréal (HSCM), the Institut universitaire en santé mentale de Montréal (IUSMM) and the CHU Sainte-Justine. We must also remember that the discovery of the potentiating of lithium by antidepressants was made by Dr. Demontigny

expected NE-SW and SE-NW structural trends and it has been designed to get 2D/3D images of the crustal structure at a regional scale. A denser 2D network of 35 OBSs has been deployed in the bay of Pozzuoli aimed at detecting and modeling reflected/converted waves from 1 the possible shallow to deep discontinuities beneath the Campi Flegrei caldera. The main target of this particular receiver lay-out is the detailed imaging of the magma chamber top, expected at 4-5 km depth, according to temperature measurements in wells and sparse seismic observations. About 5000 shots have been performed dur- ing the SERAPIS experiment, at an average spatial spacing of 125 m, for a total ship travel path of 620 km. All of the seismic lines have been re-sampled at least twice, using a staggered configuration, which results in a smaller source spacing (less than 65m). In the gulf of Pozzuoli the source array had a geometry of a 5x5 km grid, slightly shifted south with respect to the OBS array. Seismic signals produced by air- guns have been well detected up to 50-60 km distance and the whole Campi Flegrei, Ischia and Procida on-land networks have recorded high quality seismograms pro- duced by the gridded source array in the bay of Pozzuoli. Due to the extended and very dense source and receiver arrays used for SERAPIS, this campaign can provide an innovative contribution to the accurate reconstruction of the Campi Flegrei caldera structure and to the definition of its feeding system at depth. *SERAPIS group: Auger Emmanuel, Bernard Marie-Lise, Bobbio Antonella, Bonagura Mariateresa, Cantore Luciana, Convertito Vincenzo, D'Auria Luca, De Matteis Raffaella, Emolo Anto- nio, Festa Gaetano, Gasparini Paolo, Giberti Grazia, Herrero Andre, Improta Luigi, Lancieri Maria Flora, Nielsen Stefan, Nisii Vincenzo, Russo Guido, Satriano Clau- dio, Simini Mariella, Vassallo Maurizio, Bruno Pier Paolo, Buonocunto Ciro, Capello Marco, Del Pezzo Edoardo, Galluzzo Danilo, Gaudiosi Germana, Giuliana Alessio

In 1775-1783, Jean-Emmanuel Gilibert (1741-1814) stayed in Respublica Poloniae to oranize a veterinary school, the Royal Botanic Garden and the Royal School of Physicians in Grodno, and since 1781 he worked in Vilnius as Professor of Natural History at the Principal School of the Grand Duchy of Lithuania. Little is known about his work conducted in Lithuania in the field of geology and earth sciences. The author has decided, on the basis of Gilibert's publications and analysis of the literature (works of J. Garbowska and P. Daszkiewicz and others), to present his teaching and research activities in this field. In Grodno, Gilibert looked after and multiplied the collections of the natural history cabinet at the Royal School of Physicians, renowned for its rich mineralogical and fossil collections watched and admired by, among others, King Stanisław August, J. Bernoulli (1744-1807) and M. Patrin (1742-1815) who mentions the amber rosary with a different species of insects preserved in each bead. Gilibert's tours around Lithuania were the opportunity to enlarge the geological collections and to adapt them to the needs of the school. He also appreciated the importance of ordinary specimens representing the geology of the area. These specimens not only enriched the natural history cabinet, but also defined the way of working and collecting. Ha was the first to found and gather fossil animals from near Grodno. The signs of mineralogical and geological interests of Gilibert can be found in the works of other authors of that epoch (L. Viteta (1736-1809) and J. Bernoulli). In Vilnius, Gilibert conducted a one year-long full lecture on natural history (zoology, botany and mineralogy). In his lectures on mineralogy, he presented not only the systematics, but also emphasized the usefulness of minerals in medicine, for the production of ornamental items and in different sectors of the economy. He adapted the process of teaching to the needs of practical life, based on

telescope of its type in the southern hemisphere. Alternating each month, a Swedish team (headed by Anders Winnberg , OSO) and a European team (headed by Dominique Bockelée-Morvan , Observatoire de Paris) observe emission lines in the radio region of the spectrum from some of the molecules in the comet's coma (the cloud of gas and dust around the cometary "dirty-snowball" nucleus). These data are of great importance for understanding the mechanisms that are responsible for the outgassing (sublimation) of ices inside the nucleus of Comet Hale-Bopp. The observations began at SEST in September 1997 and constitute a follow-up programme of a long-term monitoring project at radio wavelengths that was started in August 1995 at the telescopes of the Institut de RadioAstronomie Millimétrique (IRAM) , the James Clerk Maxwell Telescope (JCMT) , the Caltech Submillimeter Observatory (CSO) and the Nançay radio telescope by several teams of astronomers in Europe and US [1]. Radio emission from nine molecules in the coma were studied: H 2 O (water; by means of observations of the radical OH ), CO (carbon monoxide), CH 3 OH (methanol), H 2 CO (formaldehyde), HCN (hydrogen cyanide), HNC (isomeric hydrogen cyanide), CH 3 CN (methyl cyanide), H 2 S (hydrogen sulphide) and CS (carbon sulphide).

Students Use VLA to Make Startling Brown-Dwarf Discovery

NASA Astrophysics Data System (ADS)

2001-03-01

A group of summer students making a long-shot astronomical gamble with the National Science Foundation's (NSF) Very Large Array (VLA) have found the first radio emission ever detected from a brown dwarf, an enigmatic object that is neither a star nor a planet, but something in between. Their surprising discovery is forcing experts to re-think their theories about how brown dwarfs work. The Very Large Array "Many astronomers are surprised at this discovery, because they didn't expect such strong radio emission from this object," said Shri Kulkarni, a Caltech professor who was on the team that first discovered a brown dwarf in 1995, and advisor to one of the students. "What is so cool is that this is research that probably nobody else would have tried to do because of its low chance of success. That made it ideal for summer students -- we had almost nothing to lose," said Kate Becker, a student at Oberlin College in Ohio. "The radio emission these students discovered coming from this brown dwarf is 10,000 times stronger than anyone expected," said Dale Frail, an astronomer at the National Radio Astronomy Observatory (NRAO) in Socorro, NM. "This student project is going to open up a whole new area of research for the VLA," Frail added. The students, in addition to Becker, are: Edo Berger from Caltech; Steven Ball from New Mexico Tech in Socorro, NM; Melanie Clarke from Carleton College in Northfield, MN; Therese Fukuda from the University of Denver; Ian Hoffman from the University of New Mexico in Albuquerque; Richard Mellon from The Pennsylvania State University; Emmanuel Momjian from the University of Kentucky; Nathanial Murphy from Amherst College in Amherst, MA; Stacey Teng from the University of Maryland; Timothy Woodruff from Southwestern University in Georgetown, TX; Ashley Zauderer from Agnes Scott College in Decatur, GA; and Robert Zavala from New Mexico State University in Las Cruces, NM. Frail also is an author of the research paper, published in the March

Triton's Summer Sky of Methane and Carbon Monoxide

NASA Astrophysics Data System (ADS)

2010-04-01

According to the first ever infrared analysis of the atmosphere of Neptune's moon Triton, summer is in full swing in its southern hemisphere. The European observing team used ESO's Very Large Telescope and discovered carbon monoxide and made the first ground-based detection of methane in Triton's thin atmosphere. These observations revealed that the thin atmosphere varies seasonally, thickening when warmed. "We have found real evidence that the Sun still makes its presence felt on Triton, even from so far away. This icy moon actually has seasons just as we do on Earth, but they change far more slowly," says Emmanuel Lellouch, the lead author of the paper reporting these results in Astronomy & Astrophysics. On Triton, where the average surface temperature is about minus 235 degrees Celsius, it is currently summer in the southern hemisphere and winter in the northern. As Triton's southern hemisphere warms up, a thin layer of frozen nitrogen, methane, and carbon monoxide on Triton's surface sublimates into gas, thickening the icy atmosphere as the season progresses during Neptune's 165-year orbit around the Sun. A season on Triton lasts a little over 40 years, and Triton passed the southern summer solstice in 2000. Based on the amount of gas measured, Lellouch and his colleagues estimate that Triton's atmospheric pressure may have risen by a factor of four compared to the measurements made by Voyager 2 in 1989, when it was still spring on the giant moon. The atmospheric pressure on Triton is now between 40 and 65 microbars - 20 000 times less than on Earth. Carbon monoxide was known to be present as ice on the surface, but Lellouch and his team discovered that Triton's upper surface layer is enriched with carbon monoxide ice by about a factor of ten compared to the deeper layers, and that it is this upper "film" that feeds the atmosphere. While the majority of Triton's atmosphere is nitrogen (much like on Earth), the methane in the atmosphere, first detected by

for scalability has driven different architectural designs, for example, the use of fully distributed architectures which scale well but often suffer performance costs versus centralized and hierarchical architectures in which the inverse is true. However, DVEs have also exploited the spatial nature of their domain to address scalability and have pioneered techniques that exploit the semantics of the shared space to reduce data updates and so allow greater scalability. Several of the systems reported in this special issue apply a notion of area of interest to partition the scene and so reduce the participants in any data updates. The specification of area of interest differs between systems. One approach has been to exploit a geographical notion, i.e. a regular portion of a scene, or a semantic unit, such as a room or building. Another approach has been to define the area of interest as a spatial area associated with an avatar in the scene. The five papers in this special issue have been chosen to highlight the distributed systems aspects of the DVE domain. The first paper, on the DIVE system, described by Emmanuel Frécon and Mårten Stenius explores the use of multicast and group communication in a fully peer-to-peer architecture. The developers of DIVE have focused on its use as the basis for collaborative work environments and have explored the issues associated with maintaining and updating large complicated scenes. The second paper, by Hiroaki Harada et al, describes the AGORA system, a DVE concentrating on social spaces and employing a novel communication technique that incorporates position update and vector information to support dead reckoning. The paper by Simon Powers et al explores the application of DVEs to the gaming domain. They propose a novel architecture that separates out higher-level game semantics - the conceptual model - from the lower-level scene attributes - the dynamic model, both running on servers, from the actual visual representation

Sir Fred Hoyle, 1915 2001 Astronomer, author and popularizer of science 'There is a coherent plan in the universe, but I don't know what it's a plan for...' Sir Fred Hoyle, 1915 2001 Fred Hoyle, who passed away on 20 August 2001, was one of the most important figures in 20th century physics and astronomy. He is most famous for coining the term 'Big Bang' in a BBC radio broadcast in 1950, even though the fact that his comment was an insult seems to have been lost in time. He left behind a lasting body of work, foremost of which is his work with Willy Fowler and the Burbidges on the origin of the chemical elements in the 1950s. Sir Martin Rees, Astronomer Royal and Professor at the Institute of Astronomy in Cambridge, speaking to Physics Education said 'Hoyle was a great astrophysicist, who from 1945 to 1970 contributed more good creative ideas than anyone else in the world.' Fred Hoyle was born at Bingley in the West Riding of Yorkshire in June 1915. A precocious child who knew his 12 times table aged 4 and could navigate by the stars before he was 10, he won a scholarship to Bingley Grammar School and from there moved on to Emmanuel College, Cambridge. Hoyle excelled at mathematics and won several prizes before he graduated in 1936. He became fascinated by the work of physicist Rudolf Peierls, who became his PhD supervisor, before being replaced by Maurice Pryce when Peierls departed for Birmingham. Hoyle became a fellow of St John's College, Cambridge in 1939. During the war Hoyle worked at an Admiralty radar establishment on the south coast and met Eastern European émigrés Thomas Gold and Hermann Bondi. During this time they developed the theory of continuous creation known as the Steady State Theory of the universe. This states that matter is continuously created at a small rate to replace the matter lost to the expanding universe. Around this same time Ralph Alpher, Hans Bethe and George Gamow postulated the idea of a Universe forged in a hot explosion. After

'More traditional' DFT static calculations can be applied to complex objects at interfaces, providing their vibrational spectra, and two papers in this special section illustrate such approaches. Ceccet et al extract first hyperpolarizability tensors from DFT calculations on aliphatic chains and simulate the related VSFG spectra. They also investigate the effect of different functionals on the final signatures. Liegeois et al investigate functionalized surfaces, mainly focusing on IR and Raman spectral features, and provide very precise vibrational assignments depending on chemisorption or physisorption of the adsorbed molecules.

, which sometimes collide with the planets, as seen in the spectacular impacts of Comet Shoemaker-Levy 9 on Jupiter in 1994. The leader of the ISO team that found the water vapour in the outer planets is Helmut Feuchtgruber of the Max-Planck Institut fur Extraterrestrische Physik at Garching, Germany. He works at the ISO operations centre at Villafranca, Spain. For him, the theoretical puzzle of the water vapour is full of significance for planetary science. "The upper atmosphere of the Earth is very dry because water vapour rising from the oceans or the land freezes into clouds," Feuchtgruber comments. "We would expect the same kind of lid to seal in the water vapour of the outer planets. What we see in Saturn, Uranus and Neptune probably comes from an outside source. This has important implications for our theories of the origin and evolution of all planetary atmospheres, including the Earth's." Helmut Feuchtgruber, Emmanuel Lellouch and their colleagues are preparing a theoretical analysis of the likely origin of the water vapour in the outer planets, which they hope to publish in the next few months. European success story Rated by a panel of American astronomers as "the major infrared mission of the decade", ISO is a special achievement for ESA -- and for Europe's astronomers and engineers. Advanced technology created ISO's extremely cold telescope capable of observing cool regions of the Universe. Multinational teams, with leaders in France, Germany, the Netherlands and the United Kingdom, developed the special scientific instruments. A European Ariane 44P launcher put ISO into orbit on 17 November 1995. ISO's supply of superfluid helium, which keeps the telescope and instruments cold, is expected to run out at about the end of 1997, giving it a life several months longer than required in the specification. Requests from the world's astronomers for observations with ISO have always far exceeded the available operating time, even though the spacecraft's controllers

If the RF power applied to a plasma chamber is comprised of a phase locked fundamental and its second harmonic, the ion energy is a linear function of the phase angle between the two. This simple but previously overlooked technique has proved to be an enabling technology for future materials and plasma applications. The method has been patented and is currently used, for example, by leading manufacturers of large area solar cells and has resulted in unsurpassed quality and homogeneity of the devices.

When the star moves behind the planet, the stellar rays suffer minute deviations as they are refracted (i.e., bent and defocussed) by the planet's atmospheric layers. This effect, together with the large distance to the planet, manifests itself as a gradual decline of observed intensity of the stellar light, rather than an abrupt drop as this would be the case if the planet had no atmosphere. Pluto's atmosphere was first detected on August 19, 1985, during a stellar occultation observed from Israel

Catching a Falling Star

, etc. This image was obtained by MASCOT on August 25, 2002 and shows a meteor caught in the act. (Note that this is not the meteor whose spectrum was recorded). The Milky Way is also clearly visible in the centre. A popular saying states that when you see a meteor, you may make a wish. While astronomers cannot promise that it will be realised, a team of astronomers [1] have indeed seen a dream come true! On May 12, 2002, they were lucky to record the spectrum of a bright meteor when it happened - by sheer chance and against all reasonable odds - to cross the narrow slit of the FORS1 instrument on the ESO Very Large Telescope. At the time of this unlikely event, the telescope was performing a series of 20-minute spectroscopic exposures of a supernova in a distant galaxy in order to establish constraints on the dark energy content of the Universe (see e.g. ESO PR 21/98). Thanks to its enormous light-collecting and magnifying power, the VLT recorded the spectrum of the meteor trail perpendicular to its path on one of these exposures. "We really hit the jackpot", says ESO astronomer Emmanuel Jehin: "Chances of capturing a meteor in the narrow slit of the FORS1 spectrograph are about as big as for me winning the national lottery." Meteor spectra have on occasion been obtained serendipitously during photographic star spectra surveys. But this is now maybe the only meteor spectrum recorded with a large telescope and a modern spectrograph. The spectrum covers the wavelength range from 637 to 1050 nm, which is dominated by emissions from air atoms and molecules in the meteor path and teach us about the collision processes in the wake of a meteoroid. The rapid motion of the meteor across the sky resulted in a very brief exposure while crossing the narrow spectrograph slit - only 1/50 of a millisecond! - and despite the relative brightness of the meteor it was only thanks to the VLT's great light-gathering power that any record was procured. The meteor was estimated at magnitude

Patient-reported outcomes may help inform treatment choice in advanced/metastatic renal cell carcinoma (RCC), particularly between approved targeted therapies with similar efficacy. This double-blind crossover study evaluated patient preference for pazopanib or sunitinib and the influence of health-related quality of life (HRQoL) and safety factors on their stated preference. Patients with metastatic renal cell carcinoma were randomly assigned to pazopanib 800mg per day for 10 weeks, a 2-week washout, and then sunitinib 50mg per day (4 weeks on, 2 weeks off, 4weeks on) for 10 weeks, or the reverse sequence. The primary end point, patient preference for a specific treatment, was assessed by questionnaire at the end of the two treatment periods. Other end points and analyses included reasons for preference, physician preference, safety, and HRQoL. Of 169 randomly assigned patients, 114 met the following prespecified modified intent-to-treat criteria for the primary analysis: exposure to both treatments, no disease progression before cross over, and completion of the preference questionnaire. Significantly more patients preferred pazopanib (70%) over sunitinib (22%); 8% expressed no preference (P<.001). All preplanned sensitivity analyses, including the intent-to-treat population, statistically favored pazopanib. Less fatigue and better overall quality of life were the main reasons for preferring pazopanib, with less diarrhea being the most cited reason for preferring sunitinib. Physicians also preferred pazopanib (61%) over sunitinib (22%); 17% expressed no preference. Adverse events were consistent with each drug׳s known profile. Pazopanib was superior to sunitinib in HRQoL measures evaluating fatigue, hand/foot soreness, and mouth/throat soreness. This innovative crossover trial demonstrated a significant patient preference for pazopanib over sunitinib, with HRQoL and safety as key influencing factors. Copyright © 2016 Elsevier Inc.

Notes [1]: The team consists of Eric Emsellem (Principal Investigator, Centre de Recherche Astronomique de Lyon, France), Didier Greusard and Daniel Friedli (Geneva Observatory, Switzerland), Francoise Combes (DEMIRM, Paris, France), Herve Wozniak (Marseille Observatory, France), Emmanuel Pecontal (Centre de Recherche Astronomique de Lyon, France) and Stephane Leon (University of Cologne, Germany). [2]: Black Holes represent an extreme physical phenomenon; if the Earth were to become one, it would measure no more than a few millimetres across. The gravitational field around a black hole is so intense that even light can not escape from it. [3]: On its most energetic and dramatic scale, this scenario results in a quasar , a type of object first discovered in 1963. In this case, the highly energetic centre of a galaxy completely outshines the outer structures and the "quasi-stellar object" appears star-like in smaller telescopes. Technical information about the photos PR Photo 25a/01 with NGC 1097 is a reproduction from the ESO LV archive, extracted via the Hypercat facility. It is based on a 2-hour photographic exposure in the R-band (Kodak IIIa-F emulsion + RG630 filtre) with the ESO 1-m Schmidt Telescope at La Silla and covers a field of about 35 x 35 arcmin 2. On this and the following photos, North is up and East is left. PR Photo 25b/01 of the central region of NGC 1808 was reproduced from an H-band (1.6 µm) image obtained with the IRAC2 camera (now decommissioned) at the MPG/ESO 2.2-m telescope on La Silla. The exposure time was 50 sec and the field measures 2.0 x 2.1 arcmin 2 (original pixel size = 0.52 arcsec). PR Photo 25c/01 of the central region of NGC 5728 was obtained at the 3.5-m Canada-France-Hawaii Telescope (CFHT) and the Adaptive-Optics PUEO instrument; the K-band (2.3 µm) exposure lasted 60 sec and the field measures 38 X 38 arcsec 2.
