    Improvised explosive devices (IEDs), one of today's major threats that armed forces have to cope with, are particularly menacing during field operations in which the same itinerary is used by troops on a regular basis. The detection of changes observed on an itinerary between different passages of a vehicle can be very revealing. We propose a low-cost solution implementing a GPS receiver, a three-axis magnetic compass as well as a video camera. This device, together with an image processing and computer vision scheme, allow the occupants of a vehicle to focus their attention on any visible changes occurring along their itinerary since a previous passage.

    Leisure travel has become a topic of great interest to Taiwanese residents in recent years. Most residents expect to be able to relax on a vacation during the holidays; however, the complicated procedure of travel itinerary planning is often discouraging and leads them to abandon the idea of traveling. In this paper, we design an automatic travel itinerary planning system for the domestic area (ATIPS) using an algorithm to automatically plan a domestic travel itinerary based on user intentions that allows users to minimize the process of trip planning. Simply by entering the travel time, the departure point, and the destination location, the system can automatically generate a travel itinerary. According to the results of the experiments, 70% of users were satisfied with the result of our system, and 82% of users were satisfied with the automatic user preference learning mechanism of ATIPS. Our algorithm also provides a framework for substituting modules or weights and offers a new method for travel planning.

    Kodak Optical Products has embarked on a journey that will ultimately lead to manufacturing excellence and total customer satisfaction. With quality as our compass we have already obtained ISO 9001 and Manufacturing Resource Planning (MRP) II certifications. Seeking and attaining these certifications enabled us to understand and enhance fundamentals relative to the operation of our business. This has provided a solid foundation from which we can launch continuous improvement activities. Now we continue our journey to such destinations as 10X reduction in both defects and cycle time, measuring and reducing our cost of poor quality, and upgrading our quality information system. Our presentation will emphasize our 10X improvement process and how it applies to high-volume production of precision plastic optics.

    The scope of this study is to identify and contextualize aspects of the therapeutic itineraries of patients treated at a university medical clinic specialized in nervous anorexia and bulimia. For this purpose, an attempt was made to reconstitute the succession of events triggered in 20 respondents and their families with the classification of anorexia and bulimia as "health problems." The narratives were analyzed in order to link the individual experiences and the social context of their occurrence (organization of health services, characteristics of treatment and medical knowledge and characteristics of contemporary subjectivity), in light of the theoretical studies of Public Health and Psychoanalysis. Data analysis revealed that these itineraries arise from connections and disconnections between two distinct approaches: one that organizes the management of patients and the other governing the conduct of health institutions and families. If the latter presuppose a quest for health, this is not what primarily concerns the individuals in question. Their refusal to moderate their own eating disorders is notable on their itineraries, and indicates the functionality of those practices. Such practices play a part in the reconstruction of their self-images.

  11. Goethe's Italian Journey and the geological landscape

    2015-04-01

    Over 220 years ago Johann Wolfgang von Goethe undertook a nearly two-years long and fascinating journey to Italy, a destination dreamed for a long time by the great German writer. During his journey from Alps to Sicily Goethe reflects on landscape, geology, morphology of "Il Bel Paese", sometimes providing detailed descriptions and acute observations concerning the great and enduring laws by which the earth and all within it are governed. He was an observer, with the eye of the geologist and landscape painter, as he himself stated, and therefore he had a 360 degree focus on all parts of the territory. From the Brenner Pass to Sicily, Goethe reflects on landscape, contrasting morphologies, the genesis of territories, providing detailed descriptions useful for reconstructing the conditions of the territory and crops of the late 18th century. His diary is a description of the impressions he received from the country and its people, mingled with reflections upon art, science and literature. Goethe studied mineralogical and geological phenomena and drew up notes on the life of the people, the climate and the plants. On various scientific occasions and, in particular, within the framework of the Italian Association "Geologia & Turismo", of the Working Group "Geomorphosites" of the International Association of Geomorphologists and the International Year of Planet Earth, the opportunity to re-examine Goethe's travels in Italy from a geological viewpoint was recognised. In the present paper an attempt was made to reproduce the geotourism itinerary ante litteram of the writer to Italy, one of the most important tourist destination worldwide, thanks to its rich cultural and natural heritage and the outstanding aesthetic qualities of the complex natural landscape. This project was essentially conceived with a twofold purpose. First of all, an attempt was made to reproduce the journey of a great writer, as an example of description of landscape perceived and described as

    This paper describes the birth (or rebirth) of Italian medical anthropology around the middle of the 1950s, and its subsequent complex development up to the present. During this fairly long process, the author played a role that was probably of some importance, that of both a direct witness and active participant. Here these developments are briefly reviewed, in an attempt to single out some of the stimuli and the most significant occasions that have happened, their theoretical and methodological reference points, the main lines of research that have been tackled along the way, as well as the 'social demand' and the 'social use' that have integrated and oriented the practice of the new discipline within the horizon of some of the more general problems of Italian society. In outlining here the profile of and the various events in Italian medical anthropology, this paper takes into account the fact that, although a medical anthropology with that name and the disciplinary set-up that are now internationally attributed to it began in Italy only in the mid-1950s, important lines of research to which we would today attach that name had been undertaken long ago.

    ABSTRACT OBJECTIVE To analyze explanations for tuberculosis and therapeutic itineraries of Brazilian indigenous people. METHODS Case study with a qualitative-descriptive approach. We conducted semi-structured interviews with 11 Munduruku indigenous, including direct observation of treatment for tuberculosis in the municipality of Jacareacanga, south-western region of the state of Para, Brazil. To identify explanations for tuberculosis and therapeutic itineraries, we performed thematic content analysis. RESULTS Traditional medicine was the first therapeutic option chosen by the indigenous. However, biomedicine was also employed, which indicates a circulation between different therapeutic contexts and health concepts among the Munduruku. The explanations provided ranged from recognition of the signs and symptoms specific to tuberculosis to the attribution of the disease to a spirit that leaves the body and wanders in the woods, returning ill into the body. Unlike the biomedical model, which links tuberculosis transmission strictly to interpersonal contact, in closed spaces without natural lighting and ventilation (preferably domestic environments), the Munduruku associate the disease to an indirect contact between people socially distant (enemies or adversaries) in public and open places. CONCLUSIONS The explanations made by the indigenous are unique and deserve the attention of those who are responsible for developing health public policies, as well as of the teams who work on the villages. To guarantee an efficient control of tuberculosis in these regions, it is necessary that the developed actions integrate biomedicine knowledge and the traditional medicine of the indigenous people, in addition to respecting and welcoming local culture manifestations.

    The annual run of Northwest salmon--from the vast Pacific Ocean to the mountain streams where their lives began--is one of Nature`s most awe-inspiring events. Now that modern science has discovered some of the salmon`s secrets, their journey seems even more miraculous. So unlikely is the survival of a single returning salmon that Nature compensates heavily. Of the other 3,000 to 7,000 eggs in a nest, only one spawning pair, on average, will make it back. Too much or too little water at hatching can wipe out great swarms of young fish life. Bigger fish, bears, seals--all take their share of salmon. Nature allows for these natural events. But Nature alone cannot make up for what people have done. Dams in the Columbia River Basin have blocked huge areas of the wild salmon`s spawning grounds. Roads and towns sprouted up along rivers and streams. Logging and farming practices fouled rivers and creeks. So did pollution from the cities. And it became too easy to catch fish. Salmon runs became smaller and smaller. Some types of salmon disappeared forever. Having nearly destroyed the salmon, people are now coming to their rescue. Still, important runs of Northwest native salmon are in real danger of extinction. Much remains to be done. This brochure presents a close look at the life of a wild salmon, Oncorhynchus tshawystcha.

    High density lipoprotein (HDL) and its main protein component apolipoprotein A-I (ApoA-I) have multiple anti-atherogenic functions. Some of them are exerted within the vessel wall, so that HDL needs to pass the endothelial barrier. To elucidate their itinerary through endothelial cells (ECs), we labelled ApoA-I and HDL either fluorescently or with 1.4 nm nanogold and investigated their cellular localization by using immunofluorescent microscopy (IFM) and electron microscopy (EM). HDL as well as ApoA-I is taken up by ECs into the same route of intracellular trafficking. Time kinetics and pulse chase experiments revealed that HDL is trafficked through different vesicles. HDL partially co-localized with LDL, albumin, and transferrin. HDL did not co-localize with clathrin and caveolin-1. Fluorescent HDL was recovered at small proportions in early endosomes and endosome to trans-golgi network vesicles but not at all in recycling endosomes, in late endosomes or lysosomes. EM identified HDL mainly in large filled vesicles which however upon IFM did not colocalize with markers of multivesicular bodies or autophagosomes. The uptake or cellular distribution of HDL was altered upon pharmacological interference with cytochalasine D, colchicine and dynasore. Blockage of fluid phase uptake with Amiloride or EIPA did not reduce the uptake of HDL. Neither did we observe any co-localization of HDL with dextran as the marker of fluid phase uptake. In conclusion, HDL and ApoA-I are internalized and trafficked by endothelial cells through a non-classical endocytic route. PMID:26577406

    "Journey to the Stars" is the latest and fourth space show based on storytelling from data visualization at the Rose Center for Earth and Space at the American Museum of Natural History. This twenty five minute, full dome movie production presents to planetarium audiences what the stars are, where they come from, how they vary in type and over time, and why they are important to life of Earth. Over forty scientists from around the world contributed their research to what is visualized into roughly fifteen major scenes. How this production is directed into a consolidated immersive informal science experience with learning goals is an integrative process with many inputs and concerns for scientific accuracy. The goal is a seamless merger of visualizations at varying spatial and temporal scales with acuity toward depth perception, revealing unseen phenomena, and the layering of concepts together to build an understanding of stars; to blend our common experience of them in the sky with the uncommon meaning we have come to know through science. Scripted by Louise Gikow who has worked for Children's Television Workshop, narrated by Whoopie Goldberg, and musically scored by Robert Miller, this production strives to guide audiences through challenging scientific concepts by complimenting the natural beauty the subject matter presents with understandable prose and musical grandeur. "Journey to the Stars" was produced in cooperation with NASA's Science Mission Directorate, Heliophysics Division and is in release at major planetariums, worldwide.

    A possibility of journeys through antigravity has recently been proposed, with the suggestion that Weyl-invariant extension of scalars coupled to Einstein gravity allows for an unambiguous classical evolution through cosmological singularities in anisotropic spacetimes. We compute the Weyl invariant curvature squared and find that it blows up for the proposed anisotropic solution both at the Big Crunch as well as at the Big Bang. Therefore the cosmological singularities are not resolved by uplifting Einstein theory to a Weyl invariant model.

    The conference A Stellar Journey was held in Uppsala, Sweden, 23 27June 2008, in honour of Professor Bengt Gustafsson's 65th birthday. The choice of Uppsala as the location for this event was obvious given Bengt's long-standing association with the city stemming back to his school days. With the exception of a two-year postdoc stint in Copenhagen, five years as professor at Stockholm University and two years as director of the Sigtuna foundation, Bengt has forged his illustrious professional career at Uppsala University. The symposium venue was Museum Gustavianum, once the main building of the oldest university in Scandinavia. The title of the symposium is a paraphrasing of Bengt's popular astronomy book Kosmisk Resa (in English: Cosmic Journey) written in the early eighties. I think this aptly symbolizes his career that has been an astronomical voyage from near to far, from the distant past to the present. The original book title was modified slightly to reflect that most of his work to date has dealt with stars in one way or another. In addition it also gives credit to Bengt's important role as a guiding light for a very large number of students, colleagues and collaborators, indeed for several generations of astronomers. For me personally, the book Kosmisk Resa bears particular significance as it has shaped my life rather profoundly. Although I had already decided to become an astronomer, when I first read the book as a 14-year-old I made up my mind then and there that I would study under Bengt Gustafsson and work on stars. Indeed I have remained true to this somewhat audacious resolution. I suspect that a great number of us have similar stories how Bengt has had a major influence on our lives, whether on the professional or personal level. Perhaps Bengt's most outstanding characteristic is his enthralling enthusiasm. This is equally true whether he is pondering some scientific conundrum, supervising students or performing in front of an audience, be it an

    Ancient astronomy had contributed away for the modern development of astronomy. The history of astronomy development in Ethiopian was liked with different beliefs and culture of the society. The Ethiopians were the first who invented the science of stars, and gave names to the planets, not at random and without meaning, but descriptive of the qualities which they conceived them to possess; and it was from them that this art passed, still in an imperfect state, to the Egyptians. Even though, Ethiopian’s contributions for astronomy in the world were immense but the journey of modern astronomy is still in the infant stage. The modern astronomy and space program in Ethiopia was started in 2004 in well organized form from three individuals to the public. In the past eleven years of journey of astronomy development in Ethiopia was the most challenging from national to international level. After strong struggle of a few committed individuals for the past eleven years the development of astronomy is completely changed from dark age to bright age. This paper will try to address the details of journey of astronomy in Ethiopia.

    This paper considers some of the processes through which Eugene O'Neill (1888-1953) dramatically shaped his inner life and through which he created his plays. These processes at their finest are evident in his composition of Long Day's Journey into Night (1941a). During its 21-month composition, the play went through three different versions, as evidenced by the playwright's handwritten and typed materials (O'Neill, unpublished, a, b, c, d). This paper posits that each version reflects O'Neill's changing state of mind as he began to master his instinctual life, developing increasingly rich characters and creating a painful, deeply tragic vision. Thus, this paper shows that O'Neill's great artistic achievement reflected a great psychological one.

    The hero's journey is a narrative structure identified by several authors in comparative studies on folklore and mythology. This storytelling template presents the stages of inner metamorphosis undergone by the protagonist after being called to an adventure. In a simplified version, this journey is divided into three acts separated by two crucial moments. Here we propose a discrete-time dynamical system for representing the protagonist's evolution. The suffering along the journey is taken as the control parameter of this system. The bifurcation diagram exhibits stationary, periodic and chaotic behaviors. In this diagram, there are transition from fixed point to chaos and transition from limit cycle to fixed point. We found that the values of the control parameter corresponding to these two transitions are in quantitative agreement with the two critical moments of the three-act hero's journey identified in 10 movies appearing in the list of the 200 worldwide highest-grossing films.

  20. Tutorial: Nanomedicine: destination or journey?

    NASA Astrophysics Data System (ADS)

    Haberzettl, C. A.

    2002-08-01

    Nanomedicine in a broad sense is the application of nano-scale technologies to the practice of medicine. The creation of nanodevices such as nanobots capable of performing therapeutic functions in vivo is a destination within the emerging field of nanomedicine. On the journey to that destination, significant technological advances across multiple scientific disciplines continue to be proposed, validated and commercialized. Advances in delivering therapy, miniaturization of analytical tools, improved computational and memory capabilities and developments in remote communications will be integrated allowing for the development of such nanobots. Nanomedicine is both a destination and a journey. The journey will cross new frontiers, uncover new knowledge and bring new horizons to the understanding and practice of medicine.

  1. The therapeutic itinerary in urgent/emergency pediatric situations in a Maroon community.

    Siqueira, Samylla Maira Costa; Jesus, Viviane Silva de; Camargo, Climene Laura de

    2016-01-01

    The goal was to understand the therapeutic itinerary of Maroon children in urgent/emergency situation. Is a descriptive research with a qualitative approach that uses the Health Care System model of Arthur Kleinman as its theoretical support. Participants included 12 mothers of children who had experienced any urgent or emergency medical situation. Data collection took place from December 2013 to June 2014 through semi-structured interviews with a thematic analysis of the data. The care of the child started in the "informal" subsystem, and access to a "formal" subsystem was characterized as a pilgrimage for health services. A development of specific strategies is needed to ensure and facilitate full access to the services of the professional subsystem for Maroon communities. PMID:26816175

    PubMed

    Pereira, Melissa de Oliveira; Sá, Marilene de Castilho; Miranda, Lilian

    2014-10-01

    This study analyzes the care provided to adolescents in crisis in a municipality in Greater Metropolitan Rio de Janeiro, Brazil. The article reports on a qualitative health study that used Therapeutic Itinerary and Life Narratives as the methodological resources. The principal theoretical reference was psychoanalyst René Kaës. Based on the adolescents' own verbal accounts, the study aimed to grasp the collective realities that could potentially shed light on the different types of logic and professional practices applied to care for adolescents in psychosocial crisis situations. The underlying assumption was that an approach to the dialectical nature of the crisis required maintaining a framework that would allow establishing a space for transition within which to develop the necessary conditions for disruptive and paradoxical elements to be elaborated. However, crisis care in the context studied here proved to be hampered by infrastructure issues, institutional rigidity, and fragmentation of activities, with little orientation towards inter-sector work.

    Responding to the call by Maria Puig de la Bellacasa for Science and Technology Studies to take up 'matters of care', this article cautions against equating care with positive feelings and, in contrast, argues for the importance of grappling with the non-innocent histories in which the politics of care already circulates, particularly in transnational couplings of feminism and health. The article highlights these histories by tracing multiple versions of the politics of care in a select set of feminist engagements with the pap smear and cervical cancer. Drawing on postcolonial and indigenous feminist commitments, as well as amplifying Donna Haraway's call to 'stay with the trouble', the article seeks to disturb hegemonic histories and arrangements of race, colonialism, and political economy, while simultaneously valuing divergent multi-local itineraries as relevant to technoscientific matters of care. This call for a politics of 'unsettling' care strives to stir up and put into motion what is sedimented, while embracing the generativity of discomfort, critique, and non-innocence.

    2013-04-01

    Hawaii's eighth annual Journey through the Universe, Gemini North's flagship local outreach program, engaged local as well as a host of visiting astronomy educators from across the country. Seventy-two educators enlightened over 8,000 students at 20 schools while visiting over 380 classrooms during “Journey Week” 2012. Gemini and the local observatories on Mauna Kea, the National Lunar Science Institute, the University of Hawai‘i at Hilo, ‘Imiloa Astronomy Education Center and Hawaii's Department of Education made this possible and are currently working to further extend the Journey program. The next phase of the nationally recognized educational outreach initiative, Journey 2.0, continues to include assessment and will explore the viability of funding for longitudinal studies on both students and teachers. New in 2012, we invited the public to join the astronomers, teacher and principals for a one-day STEM workshop which featured a keynote address: “Science—It's Not a Book of Knowledge… It's a Journey” led by Dr. Jeff Goldstein, Director of the National Center for Earth and Space Science Education and founder of the national Journey through the Universe program. The 2013 Journey program is scheduled for March 7-13, 2013. More information for this program can be found online at www.gemini.edu/journey.

  17. Identity, storytelling and the philanthropic journey

    PubMed Central

    Maclean, Mairi; Harvey, Charles; Gordon, Jillian; Shaw, Eleanor

    2015-01-01

    This article develops theoretical understanding of the involvement of wealthy entrepreneurs in socially transformative projects by offering a foundational theory of philanthropic identity narratives. We show that these narratives are structured according to the metaphorical framework of the journey, through which actors envision and make sense of personal transformation. The journey provides a valuable metaphor for conceptualizing narrative identities in entrepreneurial careers as individuals navigate different social landscapes, illuminating identities as unfolding through a process of wayfinding in response to events, transitions and turning-points. We delineate the journey from entrepreneurship to philanthropy, and propose a typology of rewards that entrepreneurs claim to derive from giving. We add to the expanding literature on narrative identities by suggesting that philanthropic identity narratives empower wealthy entrepreneurs to generate a legacy of the self that is both self- and socially oriented, these ‘generativity scripts’ propelling their capacity for action while ensuring the continuation of their journeys.

    PubMed

    Silva, Neide Emy Kurokawa E; Sancho, Leyla Gomes; Figueiredo, Wagner dos Santos

    2016-03-01

    This essay discusses the possibilities of conceptual and practical connections between the ideas of line of care and therapeutic itineraries, beginning with the theoretical contributions that lay the foundations for the Line of Integrated Healthcare and the hermeneutic approaches to Care. The implementation of lines of care tuned to individual and collective health needs can be glimpsed in the construction of therapeutic projects, inasmuch as they privilege the particularities of each situation in the agreement of flows of appointments, exams, and other procedures. The therapeutic project - taken as an arrangement, strategy, device, or basic dimension of Care in the work process in health - can be seen as an image that lays out a possibility of the future, which in turn is a projection conditioned by past experiences of health, illness, and life. From the criticism of explanatory models, preponderant in the studies of therapeutic itineraries, we defend the investment in approaches that privilege interpretation and understanding, capable of recuperating, contextualizing, and reconstructing trajectories, beginning with the subjects involved in the care process.

    La Longa, Federica; Lanza, Tiziana; Crescimbene, Massimo

    2013-04-01

    globalization takes us to lose sight of the concept of place in favor of the non-place, an environment free of characteristics and boundaries. This trend, if on one hand helps to share problems and solutions related to environmental protection, other hand risks producing a variety of effects that lead communities to disown the values of their territory. Instead the experience realized takes us in an opposite direction. We believe that educational projects structured on eco museum itineraries can promote in young people an experiential path of rediscovery and enhancement of the territory (genius loci). The active techniques used in the project (dramatization, creative writing, music, etc.) favored boys in the acquisition of knowledge and skills that allow enhance of territorial resources and sharing it with the community.

    In a continuation of my search for an understanding of sunlight's relationship to the health of the human organism, I created the installation A Journey Through Bui-Bui; Lifting the Purdah of Mal-Illumination. It was exhibited in 1999 at The Museum of Fine Arts, Santa Fe, New Mexico. The entire work pivots around the image of the veil worn by Muslim women, as both content and metaphor related to the issue of the absence or presence of light in the physical body. The following paper will discuss the development of concepts and the technical progression of this recently completed large-scale mixed media work. This three-roomed installation integrated life casts of the human figure covered in veils, various sculptural elements, fiber optics, and dichromated gelatin (DCG) holograms. The DCG holographic glass objects were produced with an array of glass sculpting tools. I will also briefly discuss current work evolving out of this installation, which further explored the sculptural possibilities of glass and the coating and recording of DCG on curved surfaces.

    2016-04-01

    In the framework of the studies dealing with geomorphosites mapping, many researches were carried out in the last years presenting both applied examples and proposals for tourist fruition. Researchers had to face many different challenges in transferring the knowledge about the geomorphological heritage on maps. The most relevant are those concerning the use of maps for tourist promotion, taking into account the requirements of clearness of representation of landforms and also the need of pointing out possible geomorphological hazards along tourist paths. Within the activity of the Working Group "Geomorphosites and Cultural Landscape" of AIGeo (Italian Association of Physical Geography and Geomorphology), some Italian itineraries, focused on the promotion of the geomorphological heritage by means of geotourist maps, are presented. They have the goal of: promoting landscape through its geomorphological and geological heritage; disseminating geoheritage knowledge focusing its relationships with cultural landscape and human history; assessing geomorphological hazards and possible risk situations The proposed itineraries are localised in different Italian regions and they concern: - the area around the remains of the Roman town of Ostra. The town is placed on the left side of the Misa River (Marche region, Italy), atop a stream terrace dating back to the uppermost Pleistocene-early Holocene. Detailed geomorphological field and remote-sensing mapping started in 2015. The surveying is aimed at focusing the geomorphological evolution as well as at assessing possible geomorphological hazard for both conservation and exploitation scopes. A geotourist trail is proposed with the aim of highlighting and integrating geomorphological and archaeological elements and information. - a geotourist trail along the coastal terraced slopes of Cinque Terre (Liguria, NW Italy): worldwide considered as one of the most outstanding examples of human integration with the natural landscape

    Nomura, Masayasu

    2011-01-01

    My journey into a research career began in fermentation biochemistry in an applied science department during the difficult post-World War II time in Japan. Subsequently, my desire to do research in basic science developed. I was fortunate to be a postdoctoral fellow in the United States during the early days of molecular biology. From 1957 to 1960, I worked with three pioneers of molecular biology, Sol Spiegelman, James Watson, and Seymour Benzer. These experiences helped me develop into a basic research scientist. My initial research projects at Osaka University, and subsequently at the University of Wisconsin, Madison, were on the mode of action of colicins as well as on mRNA and ribosomes. Following success in the reconstitution of ribosomal subunits, my efforts focused more on ribosomes, initially on the aspects of structure, function, and in vitro assembly, such as the construction of the 30S subunit assembly map. After this, my laboratory studied the regulation of the synthesis of ribosomes and ribosomal components in Escherichia coli. Our achievements included the discovery of translational feedback regulation of ribosomal protein synthesis and the identification of several repressor ribosomal proteins used in this regulation. In 1984, I moved to the University of California, Irvine, and initiated research on rRNA transcription by RNA polymerase I in the yeast Saccharomyces cerevisiae. The use of yeast genetics combined with biochemistry allowed us to identify genes uniquely involved in rRNA synthesis and to elucidate the mechanism of initiation of transcription. This essay is a reflection on my life as a research scientist. PMID:21456966

    success. Meanwhile, there are various initiatives that promote geotourism separately in the Molise and Campania sectors. However, a network of geotourism initiatives linking the two sectors and allowing the exploitation of the geological heritage of the Matese area as a whole is still lacking. Aim of this study is, obviously, the promotion of the geoheritage of the Matese Massif. Specific objects are to contribute to a better connectivity between its two sectors, the development of an overall geotourism network and, somehow, the establishment of the Matese National Park/Geopark. We propose a first geological itinerary that runs through the entire Matese Massif, from south to north. The proposed itinerary includes geosites of local to national relevance and various scientific interest (from Paleontology to Geomorphology). It allows also non-scientific audiences to understand the main steps of the rich geological history of the Matese Mountains and the geomorphic processes that have given rise to the high variety of paleo- and active landscapes and landforms, but also to appreciate its natural heritage.

    The perpetuation of symbioses through host generations relies on symbiont transmission. Horizontally transmitted symbionts are taken up from the environment anew by each host generation, and vertically transmitted symbionts are most often transferred through the female germ line. Mixed modes also exist. In this Review we describe the journey of symbionts from the initial contact to their final residence. We provide an overview of the molecular mechanisms that mediate symbiont attraction and accumulation, interpartner recognition and selection, as well as symbiont confrontation with the host immune system. We also discuss how the two main transmission modes shape the evolution of the symbiotic partners. PMID:20157340

  16. The charismatic journey of mastery learning.

    PubMed

    Inui, Thomas S

    2015-11-01

    A collection of articles in this issue examine the concept of mastery learning, underscoring that our journey is from a 19th-century construct for assuring skill development (i.e., completing a schedule of rotations driven by the calendar) to a 21st-century sequence of learning opportunities focused on acquiring mastery of special key competencies within clerkships or other activities. Mastery learning processes and standards have the potential to clarify learning goals and competency measurement issues in medical education. Although mastery learning methods originally focused on developing learners' competency with skillful procedures, the author of this Commentary posits that mastery learning methods may be usefully applied more extensively to broader domains of skillful practice, especially those practices that can be linked to outcomes of care. The transition to mastery-focused criteria for educational advancement is laudatory, but challenges will be encountered in the journey to mastery education. The author examines several of these potential challenges, including expansion of mastery learning approaches to effective but relational clinician advice-giving and counseling behaviors, developing criteria for choosing critical competencies that can be linked to outcomes, avoiding a excessively fragmented approach to mastery measurement, and dealing with "educational comorbidity."

  17. Journey to the center of the galaxy

    1980-08-01

    The solar system is a member of the Orion Arm of the Milky Way, far from the center of the Galaxy. This article takes the reader on a hypothetical journey from the solar system to the center of the Galaxy. Results from radio and infrared studies are used to suggest what such a journey might reveal. Traveling from the solar system toward the center, one crosses the Cygnus Arm, then the Sagittarius Arm, and then the so-called Three-kiloparsec Arm. The Arms contain a mixture of young stars as well as lots of gas and dust. Radio studies show that the Three-kiloparsec Arm is more like a ring than an arm. Inside this ring, is another ring composed of giant molecular clouds. Radio and infrared astronomers have discovered that the heart of the Galaxy is composed of matter in most perplexing states. There are three regions known within this innermost thousand light-years. First, there is a large zone of thin, hot ionized gas. Within this, there is a whirlpool of dense, warm matter. And further embedded, there seems to be a small supermassive object at the center. Possibly this object could be a blackhole. Researchers are continuing to examine, monitor, and model this mysterious region, the galactic nuclei. (SC)

    Plant foods are rich in phenolic compounds (PCs) that display multifaceted bioactions in health promotion and disease prevention. To exert their bioactivity, they must be delivered to and absorbed in the gastrointestinal (GI) tract, transported in circulation, and reach the target tissues. During the journey from ingestion to target tissues and final excretion, PCs are subjected to modifications by many factors during their absorption, deposition, metabolism and excretion (ADME) and consequently their bioefficacy may be modified. Consistent with all nutrients in foods, PCs must first be released from the food matrix through mechanical, chemical, and enzymatic forces to facilitate absorption along the GI tract, particularly in the upper small intestine section. Further, glycosylation of PCs directs the route of their absorption with glycones being transported through active transportation and aglycones through passive diffusion. After enteral absorption, the majority of PCs are extensively transformed by the detoxification system in enterocytes and liver for excretion in bile, feces, and urine. The journey of PCs from consumption to excretion appears to be comparable to many synthetic medications, but with some dissimilarities in their fate and bioactivity after phase I and II metabolism. The overall bioavailability of PCs is determined mainly by chemical characteristics, bioaccessibility, and ADME. In this review, factors accounting for variation in PCs bioavailability are discussed because this information is crucial for validation of the health benefits of PCs and their mechanism of action.

    This study aims to describe the medical itineraries followed by breast cancer women affiliated to the People's Health Insurance in San Luis Potosí, central Mexico. We used an ethnographic approach based on oral histories of 12 women diagnosed with breast cancer in the year prior to the first meeting. Two face-to-face sessions per participant lasting 60 minutes each were conducted followed by a telephone interview. Content and diachronic analyses were used. Three main itineraries were identified: (1) diagnostic process, (2) final diagnosis to treatment, and (3) cancer control and relapse. Findings suggested that infrastructure and human resources to adequately screen and timely diagnose breast cancer were scant and insufficiently trained, respectively. Deferral of medical assessment was related with lack of information about breast cancer consequences, with women being afraid of a positive result, and with economic constraints. The current screening program needs to be redesigned to prevent diagnostic delays, as these seem to explain the high frequency of advanced stages reported at the time of diagnosis.

    This article discusses the personal and professional journey of discovery experienced by a nurse lecturer as a result of engagement in a project exploring the impact of racism in the nursing classroom. The findings of the study demonstrated the existence and complexity of racism, the impact of racism on student learning, the limitations of lecturers in recognizing and addressing racism and organizational factors which perpetuate institutional racism. The authors describe the insight gained from the research process and how this has influenced the practice of the first author and how reflection and mentorship by the second author have challenged personal ethnocentricity, encouraged new ways of thinking, enhanced confidence and encouraged experiential teaching strategies. The article highlights the ways in which nurse lecturers might become culturally competent and in particular addressing issues of racism in the classroom and enabling learning which is applicable in practice.

    NASA Astrophysics Data System (ADS)

    Weber, Barbara; Pinggera, Jakob; Zugal, Stefan; Wild, Werner

    The Alaska Simulator is an interactive software tool developed at the University of Innsbruck which allows people to test, analyze and improve their own planning behavior. In addition, the Alaska Simulator can be used for studying research questions in the context of software project management and other related fields. Thereby, the Alaska Simulator uses a journey as a metaphor for planning a software project. In the context of software project management the simulator can be used to compare traditional rather plan-driven project management methods with more agile approaches. Instead of pre-planning everything in advance agile approaches spread planning activities throughout the project and provide mechanisms for effectively dealing with uncertainty. The biggest challenge thereby is to find the right balance between pre-planning activities and keeping options open. The Alaska Simulator allows to explore how much planning is needed under different circumstances.

Captain Hayes rejected the quarantine imposed by the local Junta of Sanity in Punta Arenas and also in Coronel, following his journey with the sick passengers to Valparaiso, port where he accepted a brief quarantine and medical services for the most compromised of the three patients, who unfortunately died. The knowledge about yellow fever and the applicable epidemiological measures in that time in Chile come to us through the sessions of the Superior Council of Public Hygiene. The threat that implicated the presence of the Oropesa in Chilean coasts is compared with the arrival of British pirates and corsairs in the colonial centuries, before the independence, announced with the alarm cry charque (for Sharp) is coming to Coquimbo!

    Argonaute proteins are conserved throughout all domains of life. Recently characterized prokaryotic Argonaute proteins (pAgos) participate in host defense by DNA interference, whereas eukaryotic Argonaute proteins (eAgos) control a wide range of processes by RNA interference. Here we review molecular mechanisms of guide and target binding by Argonaute proteins, and describe how the conformational changes induced by target binding lead to target cleavage. On the basis of structural comparisons and phylogenetic analyses of pAgos and eAgos, we reconstruct the evolutionary journey of the Argonaute proteins through the three domains of life and discuss how different structural features of pAgos and eAgos relate to their distinct physiological roles.

  4. A Replisome's journey through the bacterial chromosome.

    PubMed

    Beattie, Thomas R; Reyes-Lamothe, Rodrigo

    2015-01-01

    Genome duplication requires the coordinated activity of a multi-component machine, the replisome. In contrast to the background of metabolic diversity across the bacterial domain, the composition and architecture of the bacterial replisome seem to have suffered few changes during evolution. This immutability underlines the replisome's efficiency in copying the genome. It also highlights the success of various strategies inherent to the replisome for responding to stress and avoiding problems during critical stages of DNA synthesis. Here we summarize current understanding of bacterial replisome architecture and highlight the known variations in different bacterial taxa. We then look at the mechanisms in place to ensure that the bacterial replisome is assembled appropriately on DNA, kept together during elongation, and disassembled upon termination. We put forward the idea that the architecture of the replisome may be more flexible that previously thought and speculate on elements of the replisome that maintain its stability to ensure a safe journey from origin to terminus.

    In February 1992, I landed in the formerly secret city of Sarov, the Russian Los Alamos, followed a few days later by a visit to Snezhinsk, their Livermore. The briefings we received of the Russian nuclear weapons program and tours of their plutonium, reactor, explosives, and laser facilities were mind boggling considering the Soviet Union was dissolved only two months earlier. This visit began a 17-year, 41 journey relationship with the Russian nuclear complex dedicated to working with them in partnership to protect and safeguard their weapons and fissile materials, while addressing the plight of their scientists and engineers. In the process, we solved a forty-year disagreement about the plutonium-gallium phase diagram and began a series of fundamental plutonium science workshops that are now in their tenth year. At the Yonbyon reprocessing facility in January 2004, my North Korean hosts had hoped to convince me that they have a nuclear deterrent. When I expressed skepticism, they asked if I wanted to see their ``product.'' I asked if they meant the plutonium; they replied, ``Well, yes.'' Thus, I wound up holding 200 grams of North Korean plutonium (in a sealed glass jar) to make sure it was heavy and warm. So began the first of my six journeys to North Korea to provide technical input to the continuing North Korean nuclear puzzle. In Trombay and Kalpakkam a few years later I visited the Indian nuclear research centers to try to understand how India's ambitious plans for nuclear power expansion can be accomplished safely and securely. I will describe these and other attempts to deal with the nonproliferation legacy of the cold war and the new challenges ahead. )

    [figure removed for brevity, see original site] Click on the image for movie of Journey to a Star Rich with Planets

    This artist's animation takes us on a journey to 55 Cancri, a star with a family of five known planets - the most planets discovered so far around a star besides our own.

    The animation begins on Earth, with a view of the night sky and 55 Cancri (flashing dot), located 41 light-years away in the constellation Cancer. It then zooms through our solar system, passing our asteroids and planets, until finally arriving at the outskirts of 55 Cancri.

    The first planet to appear is the farthest out from the star -- a giant planet, probably made of gas, with a mass four times that of Jupiter. This planet orbits its star every 14 years, similar to Jupiter's 11.9-year orbit.

    As the movie continues, the three inner planets are shown, the closest of which is about 10 to 13 times the mass of Earth with an orbital period of less than three days.

    Zooming out, the animation highlights the newest member of the 55 Cancri family - a massive planet, likely made of gas, water and rock, about 45 times the mass of Earth and orbiting the star every 260 days. This planet is the fourth out from the star, and lies in the system's habitable zone (green). A habitable zone is the place around a star where liquid water would persist. Though the newest planet probably has a thick gaseous envelope, astronomers speculate that it could have one or more moons. In our own solar system, moons are common, so it seems likely that they also orbit planets in other solar systems. If such moons do exist, and if they are as large as Mars or Earth, astronomers speculate that they would retain atmospheres and surface liquid water that might make interesting environments for the development of life.

    The animation ends with a comparison between 55 Cancri and our solar system.

    The colors of the illustrated planets were chosen to resemble those of our own solar

    2014-02-01

    Simulation is increasingly being used as a teaching strategy in nursing education. The best learning outcomes occur when simulation is integrated into the curriculum rather than added to a crowded curriculum. Faculty are challenged to integrate simulation experiences into the curriculum in a way that promotes optimal achievement of student learning objectives. The purpose of this article is to describe the journey toward the integration of simulation in a baccalaureate nursing curriculum. A description of the journey from the beginning, through Health Resources and Services Administration funding, as a participating site in The NCSBN National Simulation Study, and through curricular redesign are presented in the context of faculty growth and lessons learned. The ultimate purpose is to provide guidance to faculty teaching in nursing programs that may be struggling with some of the same issues that beleaguered faculty during our journey.

  13. The WIPP journey to waste receipt

    Barnes, G.J.; Whatley, M.E.

    1997-04-01

    In the early 1970s the federal government selected an area in southeastern New Mexico containing large underground salt beds as potentially suitable for radioactive waste disposal. An extensive site characterization program was initiated by the federal government. This site became the Waste Isolation Pilot Plant, better known as WIPP. It is now 1997, over two decades after the initial selection of the New Mexico site as a potential radioactive waste repository. Numerous scientific studies, construction activities, and environmental compliance documents have been completed. The US Department of Energy (DOE) has addressed all relevant issues regarding the safety of WIPP and its ability to isolate radioactive waste from the accessible environment. Throughout the last two decades up to the present time, DOE has negotiated through a political, regulatory, and legal maze with regard to WIPP. New regulations have been issued, litigation initiated, and public involvement brought to the forefront of the DOE decision-making process. All of these factors combined to bring WIPP to its present status--at the final stages of working through the licensing requirements for receipt of transuranic (TRU) waste for disposal. Throughout its history, the DOE has stayed true to Congress` mandates regarding WIPP. Steps taken have been necessary to demonstrate to Congress, the State of New Mexico, and the public in general, that the nation`s first radioactive waste repository will be safe and environmentally sound. DOE`s compliance demonstrations are presently under consideration by the cognizant regulatory agencies and DOE is closer than ever to waste receipt. This paper explores the DOE`s journey towards implementing a permanent disposal solution for defense-related TRU waste, including major Congressional mandates and other factors that contributed to program changes regarding the WIPP project.

    2015-01-01

    Modeling and clustering medical inpatient journeys is useful to healthcare organizations for a number of reasons including inpatient journey reorganization in a more convenient way for understanding and browsing, etc. In this study, we present a probabilistic model-based approach to model and cluster medical inpatient journeys. Specifically, we exploit a Bayesian Hidden Markov Model based approach to transform medical inpatient journeys into a probabilistic space, which can be seen as a richer representation of inpatient journeys to be clustered. Then, using hierarchical clustering on the matrix of similarities, inpatient journeys can be clustered into different categories w.r.t their clinical and temporal characteristics. We evaluated the proposed approach on a real clinical data set pertaining to the unstable angina treatment process. The experimental results reveal that our method can identify and model latent treatment topics underlying in personalized inpatient journeys, and yield impressive clustering quality. PMID:26958200

    Hawaii will celebrate its tenth anniversary of the flagship Journey through the Universe program that began in 2004. The Gemini-led initiative has engaged hundreds of astronomers and astronomy educators that have visited over 2,700 classrooms, visiting over 60,000 students over the course of the last nine years. The scientists have brought excitement and inspiration about the life-long possibilities available in science, technology and mathematics to our students. The Journey program nurtures our students' innate curiosity, offers workshops for hundreds of teachers in Science, Technology, Engineering, and Math (STEM) education, and provides an opportunity for our community members to visit the classrooms alongside our astronomers. This ten-day annual event also includes Family Science Events that are enjoyed by thousands. For the 2013 program, our governor, Neil Abercrombie, inquired about the program and its enormous impact on Hawaii's students. Governor Abercrombie actively participated by visiting classrooms at different schools and attending our chamber of commerce appreciation event. This paper will share how the Journey program came to be and what is anticipated for the tenth anniversary. Journey through the Universe is a model outreach initiative that could be duplicated in other locations.

    2000-01-01

    We are embarking upon a cosmic journey. From the safety of our home planet Earth, scientists plan to explore the very limits of the known Universe. Our travels will take us to where space and time cease to exist as we know them, and to where the secrets of the past and future lie captured in the starlight of the present across an expanse of billions of light-years. Cosmic Journeys, a new series of NASA space science missions, will take us to the limits of gravity, space, and time. This virtual journey will use the power of resolution far greater than what current telescopes can muster to transport us to the rim of a black hole, to eagle-eye views of the galaxies and voids that pervade the Universe, and to the earliest moments of time, just fractions of a second after the Big Bang. The goal of our Cosmic Journeys is to solve the mystery of gravity, a force that is all around us but cannot be seen.

  20. "The Moon Village and Journey to Mars enable each other"

    NASA Astrophysics Data System (ADS)

    Beldavs, Vidvuds

    2016-07-01

    NASA has proposed the Journey to Mars, a multi-decade collaborative international effort to establish permanent manned operations on the Martian surface as well as in orbit, most likely on the Martian moons. NASA's proposed the Journey to Mars has come under politically motivated attack as illusory, as beyond NASA's capabilities and anticipated NASA budgets in the foreseeable future. [1]. Other concerns come from various communities of researchers concerned about securing sustaining funding for their largely robotic research missions. ESA's Director General Dietrich Woerner's proposed Moon Village faces challenges ESA member states concerned about sustaining funding for projects already underway or in planning. Both the Journey to Mars and Moon Village raise the question - who will or who can pay for it? The 2013 US Research Council study suggested potential benefits to a mission to Mars from activities on the Moon [2]. The NASA funded Flexible Lunar Architecture study came to similar conclusions using a different methodology [3]. A logistics analysis by an MIT team suggested the possibility of cost savings through use of lunar water for propellant to reach Mars [4]. The highly promising private-public financing approach has been examined for potential application to funding the costs of reaching Mars [5]. Insofar as the feasibility of utilization of lunar water has not been determined these conclusions are speculative. This study will examine the following alternative scenarios for establishing sustainable, manned operations on Mars and permanent manned operations on the Moon: A. NASA-led Journey to Mars without an ESA-led Moon Village B. ESA-led Moon Village without NASA-led Journey to Mars C. NASA-led Journey to Mars with an ESA-led Moon Village D. Shared Infrastructure scenario - NASA-led Journey to Mars with ESA-led Moon Village and with a potential JAXA-led space-based-solar power initiative E.

    This article recounts the experiences of a first cohort of graduate students in a newly implemented advanced holistic nursing (AHN) track, one of only a handful in the nation, and the first in Florida. The increasing popularity of complementary and alternative healing processes represents the insufficiency of a health system of fragmented care and a desire for holistic healing that is beyond mainstream allopathic care. Graduate holistic nurse education equips nurses to explore the commitment needed to advance the evolution of health care. The covered wagon journey is a metaphor for this meaningful participation. Students journaled their experiences as cotravelers in a lone wagon: embarking on a courageous journey, forging a path of discovery, and reaching their destination as pioneers. This cohort experience embodied the central tenets of holistic nursing, thus creating conscious change and unity within a learning community. The future of AHN is addressed in the context of the contemporary health care environment.

  2. A journey with Fred Hoyle. The search for cosmic life

    NASA Astrophysics Data System (ADS)

    Wickramasinghe, Chandra; Wickramasinghe, Kamala

    2005-01-01

    This is the story of the author's unique scientific journey with one of the most remarkable men of 20th century science. The journey begins in Sri Lanka, the author's native country, with his childhood acquaintance with Fred Hoyle's writings. The action then moves to Cambridge, where the famous Hoyle-Wickramasinghe collaborations begin. A research programme which was started in 1962 on the carbonaceous nature of interstellar dust leads, over the next two decades, to developments that are continued in both Cambridge and Cardiff. These developments prompt Hoyle and the author to postulate the organic theory of cosmic dust (which is now generally accepted), and then to challenge one of the most cherished paradigms of contemporary science - the theory that life originated on Earth in a warm primordial soup.

    In response to turbulent times within health care, many organizations are attempting to recreate their organizations. They are refocusing the workforce on the patient and family. One health care system in California and Texas has developed a professional practice model focused on the healing relationship between nurse and patient. St. Joseph Health System (SJHS), A Ministry of the Sisters of St. Joseph of Orange, has developed a model that is employed by all system entities as the infrastructure for development of Centers of Excellence. The purpose of this article is not to share the journey and development of the model, but rather to present a context for sharing the personal stories of nurses delivering care in a relationship model. The SJHS Journey to Centers of Excellence has the fundamental cornerstone of caring relationships within the vision and the caring model. PMID:13677189

    Psychiatric nurse executives and managers face an ongoing challenge to create positive professional work environments that support the recruitment and retention of the best nurses. The Pathway to Excellence program is an organizational credentialing program that designates a hospital as a workplace of choice for nursing. This article describes one psychiatric hospital's journey to become and maintain a Pathway to Excellence designation in the midst of transition. Challenges faced and novel approaches used, along the journey, are shared. The use of Appreciative Inquiry techniques has led to positive changes and heightened energy among nurses. Our experiences suggest that effective shared governance is central to a hospital's Pathway to Excellence success. We attribute the steady increase in the retention rate of nurses, in large part, to the Pathway to Excellence program.

    2013-01-01

    The objective of this study was to further develop the Ida Institute model on communication partners' (CPs) journey through experiences of person with hearing impairment (PHI), based on the perspectives of CPs. Nine CPs of hearing aid users participated in this study, recruited through the Swansea hearing impaired support group. Semi-structured interviews were conducted, the data were analysed using qualitative thematic analysis and presented with the use of process mapping approach. Seven main phases were identified in the CP journey which includes: (1) contemplation, (2) awareness, (3) persuasion, (4) validation, (5) rehabilitation, (6) adaptation, and (7) resolution. The Ida Institute model (based on professionals' perspective) was compared with the new template developed (based on CPs' perspectives). The results suggest some commonalities and differences between the views of professionals and CPs. A new phase, adaptation, was identified from CPs reported experiences, which was not identified by professionals in the Ida Institute model. The CP's journey model could be a useful tool during audiological enablement/rehabilitation sessions to promote discussion between the PHI and the CP. In addition, it can be used in the training of hearing healthcare professionals. PMID:23533422

  9. Patients as story-tellers of healthcare journeys.

    PubMed

    Lamprell, Klay; Braithwaite, Jeffrey

    2016-09-01

    There are gaps in our comprehension of patients' subjective experiences as they engage with and transit through the healthcare environments implicated in their treatment trajectories. Patients' stories, unlike patient experience data gathered in questionnaires and surveys, express the deeply personal, narrative nature of the journeys that patients take, creating opportunities for qualitative healthcare research. Yet narrative capabilities and propensities vary with individuals, and are affected by the stresses of illness and treatment. This article extends the growing interest in narrative competence training for both practitioners and patients with the investigation of a story-telling model that could facilitate patients to narrate their experiences of healthcare systems. This model is derived from the literary arts. In fiction and autobiography, the journey arc of the central character is often one in which he or she is compelled to leave the comfort of everyday life and face a series of extraordinary events involving challenge and change which forces the character towards practical, intellectual, psychological and philosophical adjustments that define, by the end of the story, the character's 'new normal'. This pattern is known as the 'hero journey'. Its parallels with patients' experiences of healthcare and the way people narrate their stories of illness have long been recognised. We present here a new idea for applying this model as a narrative structure by which patients may construct their stories about being in and moving through the healthcare system.

  10. A journey toward wholeness, a journey to God: physical fitness as embodied spirituality.

    PubMed

    Greenwood, Tracey C; Delgado, Teresa

    2013-09-01

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

  11. From the subsurface ocean of Enceladus to interplanetary space - the journey of Saturnian stream particles

    2014-05-01

    Discovered already 10 years ago at the beginning of the Cassini mission at Saturn, silica (SiO2) nanoparticles, so-called stream particles, stand out from the water-dominated world of the Saturnian system. They serve as a unique remote-sensing tool to probe the conditions at their formation sites as well as their interactions with the surroundings. This presentation will give an overview about the life journey of silica nanoparticles at the Saturnian system and the associated implications derived mainly based on the Cassini Cosmic Dust Analyser measurements. The first part of the journey starts from their source moon Enceladus. Here the formation criteria of silica nano-colloids provide detailed constraints on the subsurface ocean of Enceladus, indicating high interior temperature and current hydrothermal activities. The second part describes the processes about how nanosilica particles enter the E ring as ice grain inclusions and later become detached because of the plasma sputtering erosion. Once exposed to open space they get charged which eventually leads to their ejection from the magnetosphere into interplanetary space. During this the final stage we focus on how charged nanodust interacts with the solar wind magnetic field and how to derive solar wind information with a single spacecraft located inside the magnetosphere. It is found that a small fraction of the ejected nanoparticles is in fact sent back into the magnetosphere of Saturn because of the complex dynamical interactions with solar wind. The detection time and the dynamical properties of these 'returned' particles thus enable us to probe the solar wind magnetic field structure from inside the magnetosphere.

    2008-01-01

    This paper presents a multi-dimensional approach to knowledge translation, enabling results obtained from a survey evaluating the uptake of Information Technology within Neonatal Intensive Care Units to be translated into knowledge, in the form of health informatics capacity audits. Survey data, having multiple roles, patient care scenarios, levels, and hospitals, is translated using a structured data modeling approach, into patient journey models. The data model is defined such that users can develop queries to generate patient journey models based on a pre-defined Patient Journey Model architecture (PaJMa). PaJMa models are then analyzed to build capacity audits. Capacity audits offer a sophisticated view of health informatics usage, providing not only details of what IT solutions a hospital utilizes, but also answering the questions: when, how and why, by determining when the IT solutions are integrated into the patient journey, how they support the patient information flow, and why they improve the patient journey.

    Introduction In the past two decades, childhood vaccination coverage has increased dramatically, averting an estimated 2–3 million deaths per year. Adult vaccination coverage, however, remains inconsistently recorded and substandard. Although structural barriers are known to limit coverage, social and psychological factors can also affect vaccine uptake. Previous qualitative studies have explored beliefs, attitudes and preferences associated with seasonal influenza (flu) vaccination uptake, yet little research has investigated how participants’ context and experiences influence their vaccination decision-making process over time. This paper aims to provide a detailed account of a mixed methods approach designed to understand the wider constellation of social and psychological factors likely to influence adult vaccination decisions, as well as the context in which these decisions take place, in the USA, the UK, France, India, China and Brazil. Methods and analysis We employ a combination of qualitative interviewing approaches to reach a comprehensive understanding of the factors influencing vaccination decisions, specifically seasonal flu and tetanus. To elicit these factors, we developed the journey to vaccination, a new qualitative approach anchored on the heuristics and biases tradition and the customer journey mapping approach. A purposive sampling strategy is used to select participants who represent a range of key sociodemographic characteristics. Thematic analysis will be used to analyse the data. Typical journeys to vaccination will be proposed. Ethics and dissemination Vaccination uptake is significantly influenced by social and psychological factors, some of which are under-reported and poorly understood. This research will provide a deeper understanding of the barriers and drivers to adult vaccination. Our findings will be published in relevant peer-reviewed journals and presented at academic conferences. They will also be presented as practical

  18. Unveiling the mystery about adult ADHD: one woman's journey.

    PubMed

    Waite, Roberta; Ivey, Nicole

    2009-09-01

    Attention deficit hyperactivity disorder (ADHD), a neurobiological disorder, affects millions of individuals and can significantly impact an individual's life course. Research guidelines used in assessment, diagnosis, and treatment have focused primarily on Caucasian males generating, in part, the need to redress how gender and other contextual factors are considered. Consequently many women and persons from diverse cultural groups can be ignored or misdiagnosed. Undiagnosed and untreated women with ADHD are therefore limited in their potential to flourish socially, academically, interpersonally, and in their family roles.

    The story of how one woman, Mary Jane Mastorovich, traveled the journey from the traditional role of a nurse executive, responsible for 1,300 full-time equivalents (FTEs) and an annual budget of $166 million, to that of a major change agent in a system-wide redesign effort. Her travels and the lessons she learned along the way give insight into how to develop strategies and methods for personal and professional transformation. Her story also illustrates the balance between positional power and the power of influence as we face the roller coaster ride that will be health care delivery in the next century.

    Journey to the Nevada Test Site Radioactive Waste Management Complex begins with a global to regional perspective regarding the location of low-level and mixed low-level waste disposal at the Nevada Test Site. For decades, the Nevada National Security Site (NNSS) has served as a vital disposal resource in the nation-wide cleanup of former nuclear research and testing facilities. State-of-the-art waste management sites at the NNSS offer a safe, permanent disposal option for U.S. Department of Energy/U.S. Department of Defense facilities generating cleanup-related radioactive waste.

    The medical intensive care unit (MICU) at Georgetown University Hospital in Washington, D.C., was among the first four hospitals to be awarded the Beacon Award from the American Association of Critical- Care Nurses. The Beacon Award is given to those units that prove, through a 42-question application, how they excel and serve as a guiding light to other intensive care units. The MICU's "journey" to the award prompted an introspective look into the unit, its policies, and its methods of providing the highest quality patient care, in an environment that is supportive to the nursing staff.

    José Carlos Leite1; António José Dinis Ferreira2; Tanya Cristina de Jesus Esteves2; Célia Patrícia Martins Bento2 1Universidade Federal de Mato Grosso, Brazil; 2IPC - Escola Superior Agrária de Coimbra, Portugal Over the last three decades, deforestation in Brazil occurred systematically in the area known as the "arc of deforestation", an extensive geographical area located in the interface of the Cerrado and the Amazon biomes. This work encompasses the reasons, causes and/or motivations of that recent deforestation, focusing on the Central-West and Northern regions. A number of reasons will be presented, seeking to build an approach able to identify the deepest roots of deforestation of those regions. Our actions over the environment are framed by our cultural matrix that stream from a western philosophic attitude. This way, to understand the framework where the deforestation actions are justified requires a multidisciplinary approach to understand the deforestation of the Cerrado and Amazon biomes, since the motivations for forest destruction in Brazil are complex and not entirely understood within the domains of a single disciplinary area. To search for an isolated cause to understand the recent deforestation can only be plausible if we ignore information on what actually happens. The methodology used in this work is based on a bibliographical revision, analysis of georeferrenced information, participative processes implementation and observation of stakeholder behavior, and field research. It departs from a general vision on deforestation that initially occurred at the littoral region, by the Atlantic Rainforest, right after the arrival of the Europeans, and throughout the centuries penetrates towards the interior, hitting the Cerrado and Amazon biomes. In this last case, we focused on the Vale do Alto Guaporé region, near Bolivia, where the intensity of the deforestation was verified from 1970 to 1990. Ultimately, the final result is a mosaic of reasons

  3. Learning to reason: a journey of professional socialisation.

    One of the key attributes that health professional students and new graduates develop during professional socialisation is clinical reasoning ability. Clinical reasoning is a complex skill that is essential for professional practice. There is limited research specifically addressing how physiotherapists learn to reason in the workplace. The research reported in this paper addressed this gap by investigating how experienced physiotherapists learned to reason in daily practice. This learning journey was examined in the context of professional socialisation. A hermeneutic phenomenological research study was conducted using multiple methods of data collection including observation, written reflective exercises and repeated, semi-structured interviews. Data were analysed using phenomenological and hermeneutic strategies involving in-depth, iterative reading and interpretation to identify themes in the data. Twelve physiotherapists with clinical and supervisory experience were recruited from the areas of cardiopulmonary, musculoskeletal and neurological physiotherapy to participate in this study. Participants' learning journeys were diverse, although certain episodes of learning were common or similar. Role models, mentors and colleagues were found to be influential in the development of reasoning. An important implication for the professional socialisation of physiotherapists and other health professionals and for those involved in practice development is the need to recognise and enhance the role of practice communities in the explicit learning of clinical reasoning skills.

    The objective of this study was to explore the process of transition into fatherhood for Thai men from childbirth to the postpartum period. Forty-one first-time Thai fathers were voluntarily recruited from two hospitals in Chiang Mai, Thailand, from December 2012 to June 2013. In-depth interviews were used to collect the data, which were analyzed based on grounded theory methodology. The basic social process that emerged as the core category was termed: "the journey into fatherhood." This process was divided into three phases: labor, delivery, and family beginning. Within this process, there were various situations, challenges, and pressures, which caused many changes of mood and feelings for the first-time fathers. Throughout this process, they applied various strategies to manage their concerns and needs, in order to develop into masterly fathers. Identifying the process of the journey into fatherhood provides nurses and midwives insight into the new fathers' experiences, which will enable them to be more sensitive, respectful, and effective caregivers.

    NDS theory has been meaningfully applied to the dynamics of creativity and psychology. These complex systems have much in common, including a broad definition of "product" as new order emerging from disorder, a new whole (etymologically, 'health') out of disintegration or destabilization. From a nonlinear dynamical systems perspective, this paper explores the far-from-equilibrium zone of creative incubation: first in the Jungian night sea journey, a primordial myth of psychological and creative transformation; then in the neuroscience of mind wandering, the well-spring of creative ideation within the larger neural matrix. Finally, chaos theory grounds the elusive subject of creativity, modeling chaotic generation of idea elements that tend toward strange attractors, combine unpredictably, and produce change by means of tension between opposites, particularly notes consciousness (light) and the poetic unconscious (darkness). Examples from my own artwork illustrate this dialectical process. Considered together, the unconscious mythic sea journey, the unknowing wandering mind, and the generative paradigm of deterministic chaos suggest conditions that facilitate creativity across disciplines, providing fresh indications that the darkness of the unknown or irrational is, paradoxically, the illuminative source and strength of creativity.

    Aims This study explored the views and experiences of obese people preparing to undergo laparoscopic gastric banding (LAGB) leading up to the time of surgery. Background Weight loss surgery (WLS) is the most successful intervention available for the treatment of morbid obesity, and LAGB is among the most commonly used procedures in bariatric surgery. So far, the patient experience of deciding to undergo LAGB has been explored rarely and predominantly retrospectively. Design Semi-structured interviews took place with 23 patients about to undergo LAGB between June 2011 and March 2012. Data were analyzed using thematic analysis. Demographic and quality of life data situated the sample within the LAGB patient population. Results Three overarching themes were described. Participants were “living with obesity,” including the physical, social, and psychological challenges and consequences of being obese. These created in them a “desire to change,” expressed in multiple unsuccessful attempts to lose weight, and a quest for information, finally focusing on WLS. Eventually, “expectations toward LAGB” were formed, mainly to hand back a measure of control that enabled them to achieve, as well as ultimately to maintain, weight loss. This active process resulted in the patients' decision to undergo LAGB. When combined, these themes outline a distinct patient journey toward gastric banding. Conclusion Knowledge of the patient journey can inform both selection and care of patients awaiting gastric band surgery and is required by all health professionals working with this patient group.

    The objective of the study is to describe the planned hip-surgery care process as experienced by patients and healthcare professionals, as well as a qualitative analysis of problems. Data was collected through 3 focus group meetings with patients and healthcare professionals. We present the results in form of a patient journey model, examples of problems as expressed by patients and examples of proposed eHealth services by both patients and care professionals. The results indicate that although the patient journey is similar for most patients, their experiences are highly individual and designing eHealth to improve the patient journey will require flexibility and adaptability to the individual's needs.

  10. The reconstruction of the last itinerary of “Ötzi”, the Neolithic Iceman, by pollen analyses from sequentially sampled gut extracts

    The investigations of the Tyrolean Iceman "Ötzi" and his artefacts, discovered at a remote location high in the Eastern Alps, have contributed greatly to the knowledge of the lifestyle of Neolithic humankind. However, the events immediately prior to the Iceman's death have remained unclear and even the recently discovered arrowhead in his back does not explain conclusively the cause of death satisfactorily. From the pollen and macrofossil content of his gut, we reconstruct his travels just before his demise. Sequential sampling of the food residues in the digestive tract of the 5200 year old glacier mummy has made possible the analyses of a series of meals and, from the pollen content, the deduction of the environments in which the last meals were eaten. During his last 33 or so hours, Ötzi crossed different habitats in the Ötztal mountains over considerable distances from high up near the timber line (at about 2500 m), to low down in the zone of warmth-loving trees (about 1200 m or less), and finally very high in the zone of perennial ice (above 3000 m). These final journeys lend new weight to the "disaster" theory of Ötzi's death, which suggests that, returning from the high alpine pastures to his native village, he came into a severe conflict with his kin such that he had to flee from the community back to the high ground familiar to him, where he died.

    A short introduction is given about direct variational methods and their relation to Galerkin and moment methods, all flexible and powerful approaches for finding approximate solutions to difficult physical equations. An application of these methods is given in the form of the variational problem of minimizing the discomfort experienced during different journeys, between two fixed horizontal points while keeping the travel time constant. The analysis is shown to provide simple, yet accurate, approximate solutions of the problem and illustrates the usefulness and the power of direct variational and moment methods. It also demonstrates the problem of a priori assessing the accuracy of the approximate solutions and illustrates that the variational solution does not necessarily provide a more accurate solution than that obtained by moment methods.

    In the nearly 50 years, since the Medicare Program established funding for nursing education in the United States, there has been a steady migration away from hospital-controlled programs toward those which function as wholly owned subsidiaries within larger health care systems. Private sector health care organizations in particular are under increasing pressure to adapt at the risk of losing all of their funding. However, accomplishing this presents multiple challenges for today's nursing education programs in terms of their regulatory compliance, accreditation, autonomy, and, above all, governance model. The authors outline the journey toward, and specific challenges involved in creating, implementing and administering a new governance model, which sustains the overall mission and vision of the education institution while functioning seamlessly within a modern corporate health care system.

    Socioeconomic status can be defined by educational background and income level. An individual's socioeconomic status impacts all aspects of their lives, and their experience with breast cancer is no exception. As a medical student, I had a chance to work alongside a radiation oncologist at a side effects clinic, where patients are seen periodically to assess any adverse effects of their radiation treatment. Here, I had a chance to see patients during and after the treatment process and to hear their experiences regarding their journey to date. This experience provided me with a glimpse of the disparity that exists between breast cancer survivors of varying backgrounds and highlights the importance of identifying and addressing these issues.

    Menopause, a natural stage in a woman's reproductive life, is not an illness; yet some women experience severe enough symptoms to cause a breakdown in the body similar to illness or other major health disruptions. As part of a larger narrative analysis investigation of distress during menopause, this case study presents one woman's transformational journey through menopause, analysed through Frank's health and illness narratives - chaos, restitution and quest. The narratives were retranscribed using Labov's elements of a true story and Gee's poetic restructuring. This report of one woman's experience of distress during the menopause transition describes a poetic chaos narrative of incessant night sweats resulting in a loss of physicality and a deep-rooted belief in self-healing; a restitution narrative of restored health that mandated the surrender to a new healing discourse, experienced simultaneously as a victory and a defeat; and a quest narrative of seeking meaning, insight and new-found values and identities.

    This article provides an insightful exploration of the relationship between Sigmund Freud and the city of Trieste. Through an analysis of the correspondence between Freud and his friend Eduard Silberstein, Gandolfi follows those places visited by the future father of psychoanalysis and analyses their link to Freud's life. The journey to Trieste is considered as an experience that played a fundamental role in his future decisions as well as in the development of some of his psychoanalytic theories. The article eventually relates the ambiguous nature of the city - a peculiar space in with North and South, East and West converge - to Freud's own Triestine experience, that not only remits to his initial scientific researches, but also symbolizes a first significant contact with the world of sexuality.

    2015-05-01

    Indigenous Australians have higher levels of mental illness, self-harm, suicide and substance abuse than non-Indigenous Australians, as well as more frequent contact with the criminal justice system. These indices point to the need for strong leadership to support Close the Gap programmes that have now been implemented across Australia. This article considers leadership as a journey of learning for Australian Indigenous leaders. Through the use of story, it is suggested that a situational leadership approach, incorporating the principles of mindfulness, provides the most appropriate framework for Indigenous leaders who work with Indigenous communities. Flexible approaches are needed to meet the needs of diverse Indigenous populations, and address the complex challenges involved, including lateral violence. Such flexibility will enable Indigenous leaders and communities to work together to achieve improvements in the health outcomes, not only for Indigenous Australians, but also for Indigenous populations worldwide.

This paper describes the program, its history, planning, implementation, as well as the program's objectives and philosophy. The success of this program is documented here, as measured by continuous and expanding engagement of educators, the community, and the public, along with formal evaluation feedback and selected informal verbal testimony. The program's success also serves as justification for the planned adaptation of a version of the program in Chile in 2011 (adapted for Chilean educational and cultural differences). Finally, lessons learned are shared which have refined the program for Gemini's host communities but can also apply to any institution wishing to initiate a similar program.

    Hasselkus, B R

    1993-08-01

    This paper describes a personal journey of caregiving for a very old family member during dying and death. The phenomenology of caregiving reveals the inner struggle experienced by all caregivers, lay and professional, between the needs to support both the living and the dying of the terminally ill person. The lived experience unfolds in phases of caregiving that support a stage theory of development in professionals' work with dying persons. The concept of presencing or connecting is a vital component of terminal care and has implications for occupational therapy practice. Occupational therapists can use their knowledge and understanding of occupation to bring about connecting in the dying experience. The contributions of all participants in the dying experience--family caregivers, the dying person, and health professionals--are important as sources of mutual support in the work of dying.

    This paper examines the grid of sentiment that structures medical travel to India. In contrast to studies that render emotion as ancillary, the paper argues that affect is fundamental to medical travel's ability to ease the linked somatic, emotional, financial, and political injuries of being ill 'back home'. The ethnographic approach follows the scenes of medical travel within the Indian corporate hospital room, based on observations and interviews among foreign patients, caregivers, and hospital staff in Mumbai, New Delhi, Chennai, and Bangalore. Foreign patients conveyed diverse sentiments about their journey to India ranging from betrayal to gratitude, and their expressions of risk, healthcare costs, and cultural difference help sustain India's popularity as a medical travel destination. However, although the affective dimensions of medical travel promise a remedy for foreign patients, they also reveal the fault lines of market medicine in India.

    Aqueous precursors tailored for the deposition of thin film materials are desirable for sustainable, simple, low energy production of advanced materials. Yet the simple practice of using aqueous precursors is complicated by the multitude of interactions that occur between ions and water during dehydration. Here we use lithium polyoxoniobate salts to investigate the fundamental interactions in the transition from precursor cluster to oxide film. Small-angle X-ray scattering of solutions, total X-ray scattering of intermediate gels, and morphological and structural characterization of the lithium niobate thin films reveal the atomic level transitions between these states. The studies show that (1) lithium–[H{sub 2}Nb{sub 6}O{sub 19}]{sup 6−} has drastically different solution behaviour than lithium–[Nb{sub 6}O{sub 19}]{sup 8−}, linked to the precursor salt structure (2) in both compositions, the intermediate gel preserves the polyoxoniobate clusters and show similar local order and (3) the morphology and phases of deposited films reflect the ions behaviour throughout the journey from cluster solution to metal oxide. - Graphical abstract: Aqueous lithium polyoxoniobate salts were used to prepare lithium niobate (LiNbO{sub 3}) thin films. Fundamental studies were performed to investigate the interactions in the transition from precursor cluster to the oxide film. It was found that acid–base and ion-association chemistries of the aqueous and gel systems significantly affect the key processes in this atom-level journey. - Highlights: • Lithium polyoxoniobate clusters were synthesized with control over Li:Nb ratio as precursors for LiNbO{sub 3} films. • X-ray scattering studies in solution and the solid-state revealed differences controlled by Li:Nb ratio. • Film deposition studies revealed phase, composition and morphology is controlled by Li:Nb ratio. • Cluster to film transformation was revealed using total X-ray scattering and TGA.

  11. Journey-time exposure to particulate air pollution

    Gulliver, John; Briggs, David J.

    Journey-time exposures to particulate air pollution were investigated in Leicester, UK, between January and March 2005. Samples of TSP, PM 10, PM 2.5, and PM 1 were simultaneously collected using light scattering devices whilst journeys were made by walking an in-car. Over a period of two months, 33 pairs of walking and in-car measurements were collected along two circular routes. Average exposures while walking were seen to be higher than those found in-car for each of the particle fractions: average walking to in-car ratios were 1.2 (± 0.6), 1.5 (± 0.6), 1.3 (± 0.6), and 1.4 (± 0.6) μg m -3 for coarse (TSP-PM 10), intermediate (PM 10-PM 2.5), fine (PM 2.5-PM 1), and very fine particles (PM 1), respectively. Correlations between walking and in-car exposures were seen to be weak for coarse particles ( r=0.10, p=0.58), moderate for the intermediate particles ( r=0.49, p<0.01) but strong for fine ( r=0.89, p<0.01) and very fine ( r=0.90, P<0.01) particles. PM 10 exposures while walking were on average 70% higher than a nearby roadside fixed-site monitor whilst in-car exposures were 25% higher than the same fixed-site monitor. Particles with an aerodynamic diameter of less than 2.5 μm were seen to be highly correlated between walking and in-car particle exposures and a rural fixed-site monitor about 30 km south of Leicester.

    The story of Hakan profoundly calls attention to the dialectical relationship between the macro and the micro influences on the social and political situated nature of disability, work life expectations and the transformative power of life-long learning. All of these are reflected in Hakan's journey and his capacity to self-manage his needs and adapt in spite of disability adversity and impairment challenges at the turning points in his life. He used his ingenuity when faced with challenges by tapping into non-disabling environments (finding a university program that fit with his needs and he was able to meet standard examination expectations) and familiar human relationships (finding friends or family that agreed to read to him). His early experiences in the formal and informal labour markets that were available to him provided grounding into various workplace acumen and social requirements. In effect these experiences were part of his early employment socialization that are often overlooked as essential to being ready to shift from a job to deciding on a career in a changing labour economy. While Hakan developed his capacity and competencies to be ready for work in a viable career, the policy's of prescriptive employment for the disabled shifted slightly to open up the door to more persons with impairments. Read on to find out the details of Hakan's numerous experiences with turning points, shifts and his efforts to persist in becoming a teacher. Following this article there are reflective questions for deeper consideration and contemplation of the many relationships that shaped the journey. PMID:27286073

    The journey began for George Winter nearly 50 years ago, using pigs in a laboratory setting, as he observed the healing characteristics of acute wounds. The journey began for industry with the launch of "modern" dressings, particularly with films and hydrocolloids. And so the journey began for authors with a clinical or scientific interest in the art of wound care. For all those who have persevered in the wound care field, their endeavor is not only a vocation, but also a lifelong passion. Although some individuals do not understand such passion, others do, and they are the wound care champions and pioneers who have made this 25-year journey possible and the next 25 years exciting. Much progress has been achieved in wound care in the past 25 years, but much work still remains if the profession is to be truly recognized as a clinical specialty.

    OBJECTIVE Although shorter time to pediatric resective epilepsy surgery is strongly associated with greater disease severity, other non-clinical diagnostic and sociodemographic factors also play a role. We aimed to examine parent-reported barriers to timely receipt of pediatric epilepsy surgery. METHODS We conducted 37 interviews of parents of children who previously had resective epilepsy surgery at UCLA (2006–2011). Interviews were audio-recorded, transcribed and systematically coded using thematic analysis by two independent coders and subsequently checked for agreement. Clinical data, including `time to surgery' (age of epilepsy onset to surgery) were abstracted from medical records. RESULTS The mean time to surgery was 5.3 years (SD=3.8); surgery types included 32% hemispherectomy, 43% lobar/focal, 24% multilobar. At surgery, parents were on average 38.4 years (SD=6.6) and children were 8.2 years (SD=4.7). The more arduous and longer aspect of the journey to surgery was perceived by parents to be experienced prior to presurgical referral. The time from second anti-epileptic drug failure to presurgical referral was ≥1 year in 64% of children. Thematic analysis revealed four themes (with subthemes) along the journey to surgery and beyond: (1) recognition: “something is wrong” (unfamiliarity with epilepsy, identification of medical emergency), (2) searching and finding: “a circuitous journey” (information seeking, finding the right doctors, multiple medications, insurance obstacles, parental stress), (3) surgery is a viable option: “the right spot” (surgery as last resort, surgery as best option, hoping for candidacy), and (4) life now: “we took the steps we needed to” (a new life, giving back). SIGNIFICANCE Multi-pronged interventions targeting parent-, provider- and system-based barriers should focus on the critical presurgical referral period; such interventions are needed to remediate delays and improve access to subspecialty care for

  17. Journey to the Center of a Neutron Star

    A neutron star is not a place most would want to visit. This dense remnant of a collapsed star has a magnetic field billions of times stronger than Earth's, enough to shuffle your body's molecules long before you even land. The featureless surface is no fun either. Crushing gravity ensures that the star is a near perfect sphere, compressing all matter so that a sand-grain-sized scoop of neutron star material would weigh as much as a battleship on Earth. At least black holes offer the promise of funky singularity, time warps, and the Odyssean temptation to venture beyond a point of no return. What s a journey to a neutron star good for, one might ask? Well, for starters, it offers the possibility of confirming a theorized state of matter called quark-gluon plasma, which likely existed for a moment after the Big Bang and now might only exist in the superdense interiors of neutron stars. Beneath the neutron star crust, a kilometer-thick plate of crystalline matter, lies the great unknown. The popular theory is that the neutron star interior is made up of a neutron superfluid - a fluid without friction. With the help of two NASA satellites - the Rossi X-Ray Timing Explorer and the Chandra X-Ray Observatory - scientists are journeying to the center of a neutron star. Matter might be so compressed there that it breaks down into quarks, the building blocks of protons and neutrons, and gluons, the carrier of the strong nuclear force. To dig inside a neutron star, no simple drill bit will do. Scientists gain insight into the interior through events called glitches, a sudden change in the neutron star s precise spin rate. 'Glitches are one of the few ways we have to study the neutron star interior,' says Frank Marshall of NASA s Goddard Space Flight Center, who has used the Rossi Explorer to follow the escapades of the glitchiest of all neutron stars, dubbed the Big Glitcher and known scientifically as PSR J0537-6910.

    The 50th anniversary of Seminars in Hematology coincides with the 50th of St. Jude Children’s Research Hospital, and both milestones are inexorably linked to studies contributing to the cure of childhood acute lymphoblastic leukemia (ALL). We thought it fitting, therefore, to mark these events by traveling back in time to point out some of the achievements, institutions, study groups and individuals that have made cure of childhood ALL a reality. In many instances, progress was driven by new ideas, while in others it was driven by new experimental tools that allowed more precise assessment of the biology of leukemic blasts and their utility in selecting therapy. We also discuss a number of contemporary advances that point the way to exciting future directions. Whatever pathways are taken, a clear challenge will be to use emerging genome-based or immunologic-based treatment options in ways that will enhance, rather than duplicate or compromise, recent gains in outcome with classic cytotoxic chemotherapy. The theme of this journey serves as a reminder of the chief ingredient of any research directed to a catastrophic disease such as ALL. It is the audacity of a small group of investigators who confronted a childhood cancer with the goal of cure, not palliation, as their mindset. PMID:23953334

  19. The innovation journey of genomics and asthma research.

    2013-11-01

    This article concerns the transformative potential of medical genomics for common disease research. We analysed 13 review articles in asthma research in the period 1999 to 2008. Our aim was to understand how genomics has emerged in this research field, and the attendant changes. Motivated by Lippman's geneticisation thesis, we use the concept of an 'innovation journey' to trace how expectations of improved understanding, prevention, diagnosis and treatment structure a dynamic co-evolutionary process through which a genome-based discourse emerges. We show how the asthma researchers involved continuously struggle to define their contribution to asthma research, as well as to clinical practice. Along the way, the researchers propose changes to both the definition and the aetiological model of asthma, thus highlighting gene-gene and gene-environment interactions. It is, however, difficult to characterise this discourse as one of geneticisation. With increasing attention being given to epigenetics, metabolomics, proteomics and systems biology, the emerging picture suggests an important, but much less deterministic, role for genes.

    This article describes the author's personal journey from childhood to a career in physics. The beauty and truth that the author finds in physics has been the primary driving force and inspiration for her relentless pursuit of knowledge and her constant push for cutting-edge research, despite all obstacles and odds against her as a "double minority" (an Asian woman) in a predominantly white male profession. Based on her 20 years of research and teaching at one of the world's leading academic institutions, the California Institute of Technology, the author observes no differences between men and women in their scientific talents, thereby dispelling the misconception of possible inferiority of women as scientists. She further stresses the urgent societal needs for more talent in various sciences to address many of the important issues facing the planet. In this context, society must promote gender equality in science so that one half of the talent does not go to waste. Finally, the author shares her thoughts with young people about how to be better prepared to face the challenges in life and fulfill their dreams.

    The use of technology is transforming society-underpinning communication, information gathering and collaboration. Indeed, 2013 may prove to be the tipping point for healthcare delivery. No longer are policies and guidance documents being produced solely on the basis of cautions and negatives. We are entering a new era. Documents are now being produced that are constructive, focusing equally on positives and collaboration. Digital engagement within nursing and healthcare communities can be a tremendously positive experience; with the help of online resources, we can be part of the tipping point. From micro blogging to content communities, from collaborative projects to social networking, Web2.0 technology is providing 21st-century practitioners with opportunities we have not yet fully realised the potential of-for ourselves, our patients or our institutions. In this article, I share my personal journey, aiming to show my fellow healthcare practitioners how these technologies might be used to inform and improve nursing practice, within urology and beyond.

    32 years ago a man from the villages of Manunu (Upolu) and Fagamalo (Savai'i) and a woman from the inner-town village of Matautu tai-Apia (Upolu) gave birth to their middle child and only daughter Siautu Tiomai Alefaio. The man left a prominent position in the police department's CIB in Samoa to become a factory worker in Hellaby Meats of Mt. Wellington, New Zealand. The woman, a beautiful dancer in Aggie Grey's dance troupe and also an upcoming photographer at the age of 12, left all her aspirations of education to attain a job in order to make enough money for the prospective dream of 'making it big' in the 'land free-flowing with milk and honey'--Aotearoa New Zealand. For some years Aotearoa was exactly that, with money enough to bring over all their other siblings and eventually their mothers. My father (now a Parish minister of a Presbyterian church) and mother (an Early-Childhood educator) both self-sacrificially gave up their own hopes and dreams to pursue a bigger one--of prosperity for future generations. As a registered psychologist I have seen many journey stories similar to mine, and it is my own hope and dream that our contribution as people from "Le Vasa Pasefika" (vast ocean of the Pacific region) will inevitably pave the way for future generations to embrace all that they are and become all that they have been called to be.

    The secular practice of meditation is associated with a range of physiological and cognitive effects, including lower blood pressure, lower cortisol, cortical thickening, and activation of areas of the brain associated with attention and emotion regulation. However, in the context of spiritual practice, these benefits are secondary gains, as the primary aim is spiritual transformation. Despite obvious difficulties in trying to measure a journey without goal, spiritual aspects involved in the practice of meditation should also be addressed by experimental study. This review starts by considering meditation in the form of the relaxation response (a counterpart to the stress response), before contrasting mindfulness research that emphasizes the role of attention and alertness in meditation. This contrast demonstrates how reference to traditional spiritual texts (in this case Buddhist) can be used to guide research questions involving meditation. Further considerations are detailed, along with the proposal that research should triangulate spiritual textual sources, first person accounts (i.e., neurophenomenology), and physiological/cognitive measures in order to aid our understanding of meditation, not only in the secular context of health benefits, but also in the context of spiritual practice.

    On the heels of defending my Ph.D. in soil ecology, I headed off to northern Colorado last September for the next step in my scientific journey: working at a radio station. AGU was sponsoring me as a mass media fellow, a scientist-reporter temporarily working at a news media outlet. In graduate school I had pursued some science writing training, but I had never been employed as a journalist. I hoped the experience would help me understand why it can be hard for scientists and journalists to communicate with each other and what the barriers are to providing accurate and comprehensive coverage of science in the media. That's the kind of understanding that the fellowship program, run by the American Association for the Advancement of Science, was meant to promote. It helps scientists learn from experience about how science reporting is done, and in an age when science desks have been eliminated by most major news outlets, it puts an eye on science back in the newsroom.

    Healthcare leaders who develop a critical perspective of the relationship between culture and health; value respect for differences, inclusiveness, equity, and social justice; and use their power to enact these values in their spheres of influence, both professionally and personally, are better able to improve care for a diversity of clients. Graduate students can be assisted to develop such a critical perspective through a course designed as a journey of critical consciousness. We describe this journey that takes students through phases of awareness, reflection, and action in which they come to understand the concepts of critical theory and discourse analysis and begin to use these to create changes in their work settings in the direction of equity and social justice. We suggest broader implications for programs and invite readers to begin their own journeys of critical consciousness.

    Concern has been expressed over the welfare of horses transported from the USA for slaughter in Canada. United States Department of Agriculture owner/shipper certificates for the year 2009 were analyzed to provide quantitative information on the patterns and durations of these journeys. In 2009, horses from 16 states in the northern USA were transported to 6 equine slaughter plants in Canada. Thirty-two percent of loads were from auction centers, 33% from feedlots, and 35% from horse collection centers. The median duration of the journey was 19 h. Thirty-six percent of horses were transported for < 6 h, 11% for 6 to 18 h, 13% for 18 to 24 h, 25% for 24 to 36 h, 9% for 36 to 48 h, and apparently 6% > 48 h. Some journeys exceeded those specified in regulations and, based on other research, would put these horses at risk of negative welfare outcomes, such as dehydration, injury, and fatigue.

    In today's healthcare environment, healthcare organizations are trying to balance one foot in each oftwo boats: one for traditional fee-for-service reimbursement and one for population health and pay-for-quality reimbursement. The Baldrige Performance Excellence Program and its associated Criteria will help healthcare leaders navigate this changing environment and improve healthcare outcomes for patients while improving financial performance, enhancing the patient experience, and creating a positive work environment. This balanced approach, grounded in behaviors identified in high-performing organizations, provides leaders and their teams with the key to realizing strategic goals and long-term sustainability. The Baldrige Criteria alone will not improve an organization; rather, it is the unique and disciplined application of the Criteria to each organization that makes the difference. A Baldrige journey is not a sprint, but rather a marathon; it requires a long-term commitment to improvement at all levels of the organization. At Hill Country Memorial (HCM) Hospital in Fredericksburg, Texas, we selected the Baldrige Framework to guide our team as we embarked on a performance excellence climb that would take us from merely average to the national top io percent of performance as evaluated on important organizational metrics. HCM did not achieve overnight success; instead, we achieved year-over-year improvement in finance and growth, patient experience, quality of care, and workforce environment and engagement. The story of our climb is one of perseverance, willingness to learn from our mistakes, pursuit of innovative best practices both inside and outside of healthcare, and a team committed to providing the highest-quality service to our customers--our patients and our community.

    This paper aims to identify the lessons that should be learnt from how biofuels have been envisioned from the aftermath of the oil shocks of the 1970s to the present, and how these visions compare with biofuel production networks emerging in the 2000s. Working at the interface of sustainable innovation journey research and geographical theories on the spatial unevenness of sustainability transition projects, we show how the biofuels controversy is linked to characteristics of globalised industrial agricultural systems. The legitimacy problems of biofuels cannot be addressed by sustainability indicators or new technologies alone since they arise from the spatial ordering of biofuel production. In the 1970-80s, promoters of bioenergy anticipated current concerns about food security implications but envisioned bioenergy production to be territorially embedded at national or local scales where these issues would be managed. Where the territorial and scalar vision was breached, it was to imagine poorer countries exporting higher-value biofuel to the North rather than the raw material as in the controversial global biomass commodity chains of today. However, controversy now extends to the global impacts of national biofuel systems on food security and greenhouse gas emissions, and to their local impacts becoming more widely known. South/South and North/North trade conflicts are also emerging as are questions over biodegradable wastes and agricultural residues as global commodities. As assumptions of a food-versus-fuel conflict have come to be challenged, legitimacy questions over global agri-business and trade are spotlighted even further. In this context, visions of biofuel development that address these broader issues might be promising. These include large-scale biomass-for-fuel models in Europe that would transform global trade rules to allow small farmers in the global South to compete, and small-scale biofuel systems developed to address local energy needs in the

As assumptions of a food-versus-fuel conflict have come to be challenged, legitimacy questions over global agri-business and trade are spotlighted even further. In this context, visions of biofuel development that address these broader issues might be promising. These include large-scale biomass-for-fuel models in Europe that would transform global trade rules to allow small farmers in the global South to compete, and small-scale biofuel systems developed to address local energy needs in the

  16. Improving Ourselves for the Sake of Others: Our Baldrige Journey.

    In today's healthcare environment, healthcare organizations are trying to balance one foot in each oftwo boats: one for traditional fee-for-service reimbursement and one for population health and pay-for-quality reimbursement. The Baldrige Performance Excellence Program and its associated Criteria will help healthcare leaders navigate this changing environment and improve healthcare outcomes for patients while improving financial performance, enhancing the patient experience, and creating a positive work environment. This balanced approach, grounded in behaviors identified in high-performing organizations, provides leaders and their teams with the key to realizing strategic goals and long-term sustainability. The Baldrige Criteria alone will not improve an organization; rather, it is the unique and disciplined application of the Criteria to each organization that makes the difference. A Baldrige journey is not a sprint, but rather a marathon; it requires a long-term commitment to improvement at all levels of the organization. At Hill Country Memorial (HCM) Hospital in Fredericksburg, Texas, we selected the Baldrige Framework to guide our team as we embarked on a performance excellence climb that would take us from merely average to the national top io percent of performance as evaluated on important organizational metrics. HCM did not achieve overnight success; instead, we achieved year-over-year improvement in finance and growth, patient experience, quality of care, and workforce environment and engagement. The story of our climb is one of perseverance, willingness to learn from our mistakes, pursuit of innovative best practices both inside and outside of healthcare, and a team committed to providing the highest-quality service to our customers--our patients and our community.

    2007-03-01

    The world of physics is usually linked to a large variety of subjects spanning from astrophysics, nuclear/high energy physics, materials and optical sciences, plasma physics etc. Lesser is known about the exciting world of medical physics that includes radiation therapy physics, medical diagnostic and imaging physics, nuclear medicine physics, and medical radiation safety. These physicists are typically based in hospital departments of radiation oncology or radiology, and provide technical support for patient diagnosis and treatment in a clinical environment. This talk will focus on providing a bridge between selected areas of physics and their medical applications. The journey will first start from our understanding of high energy beam production and transport beamlines for external beam treatment of diseases (e.g., electron, gamma, X-ray and proton machines) as they relate to accelerator physics. We will then embrace the world of nuclear/high energy physics where detectors development provide a unique tool for understanding low energy beam distribution emitted from radioactive sources used in Brachytherapy treatment modality. Because the ultimate goal of radiation based therapy is its killing power on tumor cells, the next topic will be microdosimetry where responses of biological systems can be studied via electromagnetic systems. Finally, the impact on the imaging world will be embraced using tools heavily used in plasma physics, fluid mechanics and Monte Carlo simulations. These various scientific areas provide unique opportunities for faculty and students at universities, as well as for staff from research centers and laboratories to contribute in this field. We will conclude with the educational training related to medical physics programs.

  18. Exemplary care of the palliative patient: the journey shared.

    PubMed

    Perry, Beth

    2005-01-01

    Critical care involves caring for complex and acute needs of patients with life-threatening conditions. Despite skilful interventions, there are times when the care needed by patients and their families is primarily palliative. In this article, the author focuses on examples of ways nurses can make the palliative care they provide exemplary. Based on findings of a research study of outstanding palliative care nurses, the researcher describes the possible effect providing excellent palliative care may have on both the patient and the caregiver. Critical care nurses are often called to stand in the shadow of grief that accompanies death. Yet in doing so, these caregivers can be molded into more caring and compassionate people, and more exemplary nurses. Nurses in critical care are challenged daily to meet the multiple needs of patients and their families. Though state of the art technology, medications and advanced skills may save many lives, there are times when the care that is required is palliative. It is in these instances that a nurse 's strength and courage may be tested. By taking up this challenge, and sharing the final journey with patients, a nurse may learn many lessons. In part, caregivers may come to see that sometimes death is neither an enemy, nor a failure. Rather, sometimes death can lead to a more joyous embracing of life. Sometimes death is the only way that suffering can be erased. This article includes a description of key ways critical care nurses may address the needs of patients who are palliative. Specifically, the themes of helping people live on, individualizing care, defending human dignity, sensitive listening, sharing hope, and keeping the promise to never abandon are described. These themes all fall under the overarching theme of simple gestures, which is also described in this report. PMID:17725264

    Rodhe, Allan; Grip, Harald

    2015-04-01

    The International Hydrological Decade (IHD) 1965-1974, sponsored by UNESCO, initiated a research effort for coordinating the fragmented branches of hydrology and for understanding and quantifying the hydrologic cycle on various scales, from continents to small catchments. One important part of the Swedish IHD-program was to quantify the terms of the water budget, including detailed data on soil water and groundwater storage dynamics, of several medium sized to small. As an outcome of these studies and subsequent process oriented studies, a new view of the runoff process in forested till soils was developed in the 1970's, stressing the dominating role of groundwater in delivering water to the streams and the usefulness of subdividing catchments into recharge and discharge areas for groundwater for understanding the flowpaths of water. This view contrasted with the general view among the public, and also among professionals within the field and in text books, according to which overland flow is the main process for runoff. With this latter view it would, for instance, not be possible to understand stream water chemistry, which had become an important question in a time of growing environmental concern. In order to decrease the time lag between research results and practice, the Swedish Natural Science Research Council initiated a text book project for presenting the recent results of hydrologic research on stream flow generation applied to Swedish conditions, and in 1985 our book "Water's Journey from Rain to Stream" was published. Founded on the basic principles for water storage and flow in soils, the book gives a general picture of the water flow through the forested till landscape, with separate chapters for recharge and discharge areas. Chemical processes along the flowpaths of water are treated and the book concludes with a few applications to current issues. The book is written in Swedish and the target audience is those working professionally with water and

  1. From molten salts to ionic liquids: a "nano" journey.

    PubMed

    Dupont, Jairton

    2011-11-15

    Ionic liquids (ILs), a special group of classical molten salts, are widely used in various fields of science. Historically, researchers have tested ILs out of curiosity or to improve a specific property in a particular system in many areas of chemistry or materials science. However, today, ILs are far from being simple chemical curiosities and sit at the center of various green industrial innovation processes, where they play important roles in materials extraction, reactive catalytic supports, spatial devices, and biotransformations. In this Account, we describe a journey into a nanostructured universe to better understand the unique properties of ionic liquids and their modern applications. Because molten salts have been known for centuries and have found limited uses, we try to explain why modern nonaqueous ILs deserve increased interest and curiosity. We discuss the characteristics that distinguish modern nonaqueous ILs and compare them with classical molten salts. One of the main differences between room temperature ILs, especially those based on imidazolium cations, and simple molten salts, is the molecular asymmetry built into at least one of the ions. This asymmetry in modern, nonaqueous ILs opposes the strong charge ordering due to ionic interactions that normally would cause the system to crystallize. In addition, the presence of a cooperative network of hydrogen bonds between the cations and anions induces structural directionality (the entropic effect). Therefore, modern ILs form preorganized structures, mainly through hydrogen bonding, that induce structural directionality. In contrast, classical salts form aggregates only through ionic bonds. In other words, weak interactions order the structures in modern ILs while charges order the structure within classical salts. ILs cannot be regarded as merely homogeneous solvents. In fact, ILs form extended hydrogen-bond networks with polar and nonpolar nano domains and therefore are by definition

  4. Road transport of farm animals: effects of journey duration on animal welfare.

    PubMed

    Nielsen, B L; Dybkjær, L; Herskin, M S

    2011-03-01

    Transport of farm animals gives rise to concern about their welfare. Specific attention has been given to the duration of animal transport, and maximum journey durations are used in legislation that seek to minimise any negative impact of transport on animal welfare. This paper reviews the relatively few scientific investigations into effects of transport duration on animal welfare in cattle, sheep, horses, pigs and poultry. From the available literature, we attempt to distinguish between aspects, which will impair welfare on journeys of any duration, such as those associated with loading, and those aspects that may be exacerbated by journey time. We identify four aspects of animal transport, which have increasing impact on welfare as transport duration increases. These relate to (i) the physiological and clinical state of the animal before transport; and - during transport - to (ii) feeding and watering; (iii) rest and (iv) thermal environment. It is thus not journey duration per se but these associated negative aspects that are the cause of compromised welfare. We suggest that with a few exceptions, transport of long duration is possible in terms of animal welfare provided that these four issues can be dealt with for the species and the age group of the animals that are transported.

    The motivation for rosacea patients to seek and adhere to treatment is not well characterized. A patient journey is a map of the steps a patient takes as he/she progresses through different segments of the disease from diagnosis to management, including all the influences that can push him/her toward or away from certain decisions. We sought to examine each step of the rosacea patient journey to better understand key patient care boundaries faced by rosacea patients. A PubMed search of articles indexed for MEDLINE as well as a search of the National Rosacea Society Web site (http://www.rosacea.org) were conducted to identify articles and materials that quantitatively or qualitatively described rosacea patient experiences. Current literature pertaining to the rosacea patient journey was summarized. The rosacea patient journey is discussed. It is a useful tool to gain insight on patient experiences. Better understanding of the patient perspective by dermatologists can lead to better patient adherence to treatment and thus improved quality of life and satisfaction.

  15. The rosacea patient journey: a novel approach to conceptualizing patient experiences.

    PubMed

    Kuo, Sandy; Huang, Karen E; Davis, Scott A; Feldman, Steven R

    2015-01-01

    The motivation for rosacea patients to seek and adhere to treatment is not well characterized. A patient journey is a map of the steps a patient takes as he/she progresses through different segments of the disease from diagnosis to management, including all the influences that can push him/her toward or away from certain decisions. We sought to examine each step of the rosacea patient journey to better understand key patient care boundaries faced by rosacea patients. A PubMed search of articles indexed for MEDLINE as well as a search of the National Rosacea Society Web site (http://www.rosacea.org) were conducted to identify articles and materials that quantitatively or qualitatively described rosacea patient experiences. Current literature pertaining to the rosacea patient journey was summarized. The rosacea patient journey is discussed. It is a useful tool to gain insight on patient experiences. Better understanding of the patient perspective by dermatologists can lead to better patient adherence to treatment and thus improved quality of life and satisfaction. PMID:25671443

  5. A network-based approach for estimating pedestrian journey-time exposure to air pollution.

    PubMed

    Davies, Gemma; Whyatt, J Duncan

    2014-07-01

    Individual exposure to air pollution depends not only upon pollution concentrations in the surrounding environment, but also on the volume of air inhaled, which is determined by an individual's physiology and activity level. This study focuses on journey-time exposure, using network analysis in a GIS environment to identify pedestrian routes between multiple origins and destinations throughout the city of Lancaster, North West England. For each segment of a detailed footpath network, exposure was calculated accounting for PM2.5 concentrations (estimated using an atmospheric dispersion model) and respiratory minute volume (varying between individuals and with slope). For each of the routes generated the cumulative exposure to PM2.5 was estimated, allowing for easy comparison between multiple routes. Significant variations in exposure were found between routes depending on their geography, as well as in response to variations in background concentrations and meteorology between days. Differences in physiological characteristics such as age or weight were also seen to impact journey-time exposure considerably. In addition to assessing exposure for a given route, the approach was used to identify alternative routes that minimised journey-time exposure. Exposure reduction potential varied considerably between days, with even subtle shifts in route location, such as to the opposite side of the road, showing significant benefits. The method presented is both flexible and scalable, allowing for the interactions between physiology, activity level, pollution concentration and journey duration to be explored. In enabling physiology and activity level to be integrated into exposure calculations a more comprehensive estimate of journey-time exposure can be made, which has potential to provide more realistic inputs for epidemiological studies.

  6. BOOK REVIEW: A Journey with Fred Hoyle (Second Edition)

    NASA Astrophysics Data System (ADS)

    Wickramasinghe, Chandra; Sterken, Christiaan

    2013-12-01

    I read A Journey with Fred Hoyle: The Search for Cosmic Life shortly after the first edition appeared in 2005. The second expanded edition of this remarkable autobiographical account brings the scientific story up to date. The added Epilogue offers reflections in 2012, and shows that some of Hoyle's and Wickramasinghe's heretical theories have become accepted science today: these scientists were among the forerunners of today's astrobiology. The book is the story - presented as a blend of personal anecdotes, travel stories, references to political and social events, and science writing - of the remarkable 40-year friendship and scientific collaboration between the British astrophysicist Fred Hoyle and the Sri Lankan mathematician and astronomer Chandra Wickramasinghe. The author illuminates the story of his collaboration with Hoyle with interesting aspects of his personal life, such as the description of his educational background in Sri Lanka, and the story of how he, as a PhD student, made his first contact with his supervisor in 1960. The book also offers insights into Hoyle's and Wickramasinghe's family lives. The narrative also contains plenty of interstellar astrophysics along with the stories. Sir Fred Hoyle (1915-2001) was famous for his contribution to the theory of stellar nucleosynthesis, renowned for his coining (on BBC radio) of the term Big Bang and for his later rejection of that theory (coupled to his advocacy of the steady state cosmology), and famed as writer of more than a dozen science-fiction stories. He was the founding director of the Cambridge Institute of Theoretical Astronomy (that later became the Institute of Astronomy). Hoyle was a scientific whistleblower, a radical troublemaker, an unorthodox scientific mind, but also a victim of the system. Hoyle-Wickramasinghe thought was a long-term assault on conventional thinking: especially their notable concept of panspermia (that ever-present life pervades our universe) and their opposition to

    Progress in surgical practice has paralleled the civilizational evolution. Surgery has progressed from being the last resort in saving life to being form and function preserver. Post-renaissance Industrial age gave an impetus to this march of surgery. The currently on going digital technological revolution has further catalysed this march. Having achieved the stabilized and acceptable clinical outcomes, the surgeon has embarked on a journey of improving patient reported outcomes (PRO). Improvement in PROs with the advent of laparoscopic surgery with the attendant emphasis on minimising invasion has led to debates about invasion being just parietal or holistic in physiological sense. There is a concern that parietal invasiveness shouldn't be a trade-off for compromised clinical outcomes. Single Incision Laparoscopic Surgery (SILS) in its current avatar with current instrumentation seems to be an enthusiastic bandwagon rolling on with the cosmetic benefits acting as veil to hide the potential clinical concerns. History of surgical innovations is riddled with tales of vindictiveness and vicissitude. Lest the same fate befalls SILS we would do better to examine the SILS bandwagon in its current form till the emerging technologies address the current concerns. PMID:23730050

The most important lessons I have learned are that great people, "Giants" as I call them, are generous of spirit, creative, insightful, sharing, and caring, and second, that collaboration is really the only way to do what I want to get done. I have been very fortunate to have worked with many outstanding people. As someone said to me at the Prentice Medal presentation, "I don't like you very much but the people you work with are wonderful."My journey started with a PhD investigation into seeing if orthokeratology could control myopia at the City University London in 1966. It then moved to Australia where all aspects of contact lenses were researched to try to make contact lenses safer and more effective by understanding the cornea and anterior eye systems. That journey has now turned to making contact lenses the best they can be to slow the progress of myopia. An extremely high proportion of people who are involved with global eye care initiatives and ambitious projects to develop treatments and interventions for the major vision problems impacting the world are a joy to work with. Evidence-based systems for delivering vision to the more than 600 million people globally that are blind or vision impaired because of uncorrected refractive error have involved amazing people and collaborations. This article pays tribute to the generosity and humanity of my family and the Giants in and outside the field, and many more not so well known, and the people I work with, who have punctuated and greatly enriched this journey and made many of the scientific advances documented here possible.

  12. An Evaluation of Understandability of Patient Journey Models in Mental Health

    PubMed Central

    2016-01-01

    Background There is a significant trend toward implementing health information technology to reduce administrative costs and improve patient care. Unfortunately, little awareness exists of the challenges of integrating information systems with existing clinical practice. The systematic integration of clinical processes with information system and health information technology can benefit the patients, staff, and the delivery of care. Objectives This paper presents a comparison of the degree of understandability of patient journey models. In particular, the authors demonstrate the value of a relatively new patient journey modeling technique called the Patient Journey Modeling Architecture (PaJMa) when compared with traditional manufacturing based process modeling tools. The paper also presents results from a small pilot case study that compared the usability of 5 modeling approaches in a mental health care environment. Method Five business process modeling techniques were used to represent a selected patient journey. A mix of both qualitative and quantitative methods was used to evaluate these models. Techniques included a focus group and survey to measure usability of the various models. Results The preliminary evaluation of the usability of the 5 modeling techniques has shown increased staff understanding of the representation of their processes and activities when presented with the models. Improved individual role identification throughout the models was also observed. The extended version of the PaJMa methodology provided the most clarity of information flows for clinicians. Conclusions The extended version of PaJMa provided a significant improvement in the ease of interpretation for clinicians and increased the engagement with the modeling process. The use of color and its effectiveness in distinguishing the representation of roles was a key feature of the framework not present in other modeling approaches. Future research should focus on extending the pilot

  14. The college journey and academic engagement: how metaphor use enhances identity-based motivation.

    PubMed

    2014-05-01

    People commonly talk about goals metaphorically as destinations on physical paths extending into the future or as contained in future periods. Does metaphor use have consequences for people's motivation to engage in goal-directed action? Three experiments examine the effect of metaphor use on students' engagement with their academic possible identity: their image of themselves as academically successful graduates. Students primed to frame their academic possible identity using the goal-as-journey metaphor reported stronger academic intention, and displayed increased effort on academic tasks, compared to students primed with a nonacademic possible identity, a different metaphoric framing (goal-as-contained-entity), and past academic achievements (Studies 1-2). This motivating effect persisted up to a week later as reflected in final exam performance (Study 3). Four experiments examine the cognitive processes underlying this effect. Conceptual metaphor theory posits that an accessible metaphor transfers knowledge between dissimilar concepts. As predicted in this paradigm, a journey-metaphoric framing of a possible academic identity transferred confidence in the procedure, or action sequence, required to attain that possible identity, which in turn led participants to perceive that possible identity as more connected to their current identity (Study 4). Drawing on identity-based motivation theory, we hypothesized that strengthened current/possible identity connection would mediate the journey framing's motivating effect. This mediational process predicted students' academic engagement (Study 5) and an online sample's engagement with possible identities in other domains (Study 6). Also as predicted, journey framing increased academic engagement particularly among students reporting a weak connection to their academic possible identity (Study 7).

  16. Sockeye Salmon Retain Immunoglobulin-Secreting Plasma Cells Throughout Their Spawning Journey And Post-spawning

    2013-01-01

    Antibody-producing plasma cells are a major source of protective immunity in vertebrates, including salmon. During the spawning phase, salmon undergo drastic, hormonally driven changes in their physiology, including elevated levels of cortisol, which are known to suppress the immune system. As adult fish need to survive their long journey to the spawning grounds, we hypothesized that humoral immunity, in the form of IgM-secreting plasma cells, remains functional until post-spawning. This was investigated by measuring changes in membrane and secreted immunoglobulin heavy chain mu and Pax5 transcripts in spleen and kidney from migrating sockeye salmon, using real-time qPCR. As an additional measurement, the abundance of developing B, mature B, and plasma cells was determined in spawning fish, using flow cytometry. Immune tissue samples were collected from fish from the Kenai River drainage and Main Bay, Prince William Sound. Our results reveal that spawning fish express high levels of secreted heavy chain mu transcripts in their spleen and anterior kidney throughout the spawning journey. Furthermore, we show that IgM-secreting PCs (HCmu++/Pax5−) remain abundant in anterior kidney and spleen of post-spawning sockeye salmon, with a concomitant loss in developing B cells (HCmu−/Pax5+). This suggests that successful spawners retain their PCs throughout the spawning journey and post-spawning. PMID:23434463

    2015-06-01

    The ease of travelling between cities has contributed much to globalization. Yet, it poses a threat on epidemic outbreaks. It is of great importance for network science and health control to understand the impact of frequent journeys on epidemics. We stress that a new framework of modelling that takes a traveller’s viewpoint is needed. Such integrated travel network (ITN) model should incorporate the diversity among links as dictated by the distances between cities and different speeds of different modes of transportation, diversity among nodes as dictated by the population and the ease of travelling due to infrastructures and economic development of a city, and round-trip journeys to targeted destinations via the paths of shortest travel times typical of human journeys. An example is constructed for 116 cities in China with populations over one million that are connected by high-speed train services and highways. Epidemic spread on the constructed network is studied. It is revealed both numerically and theoretically that the traveling speed and frequency are important factors of epidemic spreading. Depending on the infection rate, increasing the traveling speed would result in either an enhanced or suppressed epidemic, while increasing the traveling frequency enhances the epidemic spreading.

  19. Utility of passive photography to objectively audit built environment features of active transport journeys: an observational study

    PubMed Central

    2013-01-01

    Background Active transport can contribute to physical activity accumulation and improved health in adults. The built environment is an established associate of active transport behaviours; however, assessment of environmental features encountered during journeys remains challenging. The purpose of this study was to examine the utility of wearable cameras to objectively audit and quantify environmental features along work-related walking and cycling routes. Methods A convenience sample of employed adults was recruited in New Zealand, in June 2011. Participants wore a SenseCam for all journeys over three weekdays and completed travel diaries and demographic questionnaires. SenseCam images for work-related active transport journeys were coded for presence of environmental features hypothesised to be related to active transport. Differences in presence of features by transport mode and in participant-reported and SenseCam-derived journey duration were determined using two-sample tests of proportion and an independent samples t-test, respectively. Results Fifteen adults participated in the study, yielding 1749 SenseCam images from 30 work-related active transport journeys for coding. Significant differences in presence of features were found between walking and cycling journeys. Almost a quarter of images were uncodeable due to being too dark to determine features. There was a non-significant tendency for respondents to under-report their journey duration. Conclusion This study provides proof of concept for the use of the SenseCam to capture built environment data in real time that may be related to active transportation. Further work is required to test and refine coding methodologies across a range of settings, travel behaviours, and demographic groups. PMID:23575288

  2. Clinical pathology services: remapping our strategic itinerary.

    2010-07-01

    Both technological advances and economic drivers have led to major changes in clinical laboratories across the world, with vastly improved testing productivity. However, the production process capability advances have far outpaced the clinical pathologists' success in assuring optimal test utilization and interpretation. While productivity of 'commodity' testing increases, our healthcare value productivity decreases. Such developments constitute a serious threat to our clinical pathology specialty, not only because pathologists may lose direct control of the commodity testing production activities, but also because the present evolution exposes a failure of our core clinical activities, the pathologist's knowledge processes that translate 'commodity' results into medical outcomes optimization. At a time when a revolution in health care organization is inescapable in the years ahead, clinical pathology must proceed from a merely reactive strategy (to fulfill the 'more with less' demands) to a proactive strategy where we build excellence and visibility in knowledge services on a strong foothold of operational excellence. Based on a Strengths-Weaknesses-Opportunities-Threats analysis, we argue that clinical pathology should safeguard and expand its healthcare value productivity by assuming leadership in building integrated laboratory services networks. We also suggest that the core knowledge processes deserve a system approach, for example, by applying a risk-based quality management system. PMID:20491600

    2013-12-01

    Australia's AuScope provides world class research infrastructure as a framework for understanding the structure and evolution of the Australian continent. Since it conception in 2005, Data Scientists have led the Grid and Interoperability component of AuScope. The AuScope Grid is responsible for the effective management, curation, preservation and analysis of earth science data across the many organisations collaborating in AuScope. During this journey much was learned about technology and architectures but even more about organisations and people, and the role of Data Scientists in the science ecosystem. With the AuScope Grid now in operation and resulting techniques and technologies now underpinning Australian Government initiatives in solid earth and environmental information, it is beneficial to reflect upon the journey and observe what has been learned in order to make data science routine. The role of the Data Scientist is a hybrid one, of not quite belonging and yet highly valued. With the skills to support domain scientists with data and computational needs and communicate across domains, yet not quite able to do the domain science itself. A bridge between two worlds, there is tremendous satisfaction from a job well done, but paradoxically it is also best when it is unnoticeable. In the years since AuScope started much has changed for the Data Scientist. Initially misunderstood, Data Scientists are now a recognisable part of the science landscape in Australia. Whilst the rewards and incentives are still catching up, there is wealth of knowledge on the technical and soft skills required and recognition of the need for Data Scientists. These will be shared from the AuScope journey so other pilgrims may progress well.

    In 1980, Peter Franken, the second director of the Optical Sciences Center, recruited an international quartet of faculty members from the US, Canada, England and Israel (DS). Peter shaped the Center as a clockwork operation, nailing down every aspect of its administration, business model and academic vision. I found myself from day one in a highly competitive environment with extreme peer pressure to make good science and generate a lot of funds. This paper describes the academic journey through my three decades at the Optical Sciences Center that became the College of Optical Sciences (Optical Sciences, in short) until my retirement in 2010, by highlighting selected areas of my group's research.

    The author uses Joseph Campbell's (1949) account of the "Journey of the Hero" to examine a sequence of stages in which the hero must first use omnipotence in order to embark on an adventure, and then relinquish it in order to return to the ordinary world. The author detects parallels to this theme in descriptions of the fate of Lucifer in Milton's Paradise Lost (1674), and in the development of toddlers as described in Mahler's (1972) observations on separation-individuation. Finally, he traces a similar process in clinical material drawn from near the end of a patient's analysis.

  8. Speaking of privilege: family therapy educators' journeys toward awareness and compassionate action.

    2012-06-01

    This study explores how family therapy educators from privileged social locations understand issues of privilege and the process by which they integrate their personal and professional journeys to create and model equity in family therapy training and professional development. These educators developed awareness about issues of privilege and oppression and owned their privilege. Increased awareness involved personal struggles with guilt and managing internalized voices of prejudice that are constantly reinforced in society. These educators adopted a stance of action and accountability for equity. We hypothesize that the process leading to owning one's privilege involves the ability to be compassionate for others' suffering and one's own limitations.

    Oakley, Ann

    2016-06-01

    The sociology of childbirth emerged in the 1970s largely as a result of influences from outside sociology. These included feminism, maternity care activism, the increasing medicalisation of childbirth, and evidence-based health care. This paper uses the author's own sociological 'career' to map a journey through four decades of childbirth research. It demonstrates the importance of social networks and interdisciplinary work, particularly across the medical-social science divide and including cross-cultural perspectives, argues that the study of reproduction has facilitated methodological development within the social sciences, and suggests that childbirth remains on the periphery of mainstream sociological concerns.

In particular, it analyses how caregivers perceive and, thus, present their experiences of the ever intensifying caregiving activity in terms of a 'journey'. In doing so, this work takes into account both the patient's continuing bodily as well as cognitive decline and its intricately linked influence on the caregiver's physical and emotional stability. Equally, this study investigates how caregivers portray memory loss, and how their portrayal fits into our conceptualisation of illness narratives and the culture of autobiographical writing.

    Sustained, high-performance nursing leadership can be effectively guided by caring theory. While much of leadership performance is manifested by external behaviors, highly effective leaders are also grounded by internal work of self-reflection and growth. This article focuses primarily on the inward journey of leadership as guided by Jean Watson's Theory of Human Caring. Key elements of the theory are interpreted within the context of the emerging, urgent, high-stakes challenges of the current healthcare environment. The links between self-nurturance and caring-healing leadership of others are explored.

    2011-03-01

    One of the major challenges in single molecule microscopy concerns 3D tracking of single molecules in cellular specimens. This has been a major impediment to study many fundamental cellular processes, such as protein transport across thick cellular specimens (e.g. a cell-monolayer). Here we show that multifocal plane microscopy (MUM), an imaging modality developed by our group, provides the much needed solution to this longstanding problem. While MUM was previously used for 3D single molecule tracking at shallow depths (~ 1 micron) in live-cells, the question arises if MUM can also live up to the significant challenge of tracking single molecules in thick samples. Here by substantially expanding the capabilities of MUM, we demonstrate 3D tracking of quantum-dot labeled molecules in a ~ 10 micron thick cell monolayer. In this way we have reconstructed the complete 3D intracellular trafficking itinerary of single molecules at high spatial and temporal precision in a thick cell-sample.

    It has been said that you cannot improve what you cannot measure. At Eli Lilly and Company, measurement is one of the five pillars of Total Quality. Quality Assurance and Toxicology have partnered in the use of measures to drive improvements in both areas. Quality Assurance and Toxicology have embarked on a journey in Total Quality to achieve customer satisfaction and drive continuous improvement. Measurement in the research and development world has traditionally not been well received. Contrary to popular belief, we have found that many processes can be measured in the research and development environment. Measurement is critical to the continuous improvement of processes because improvements are made using data. In Quality Assurance and Toxicology, the initial measures were put in place to gather baseline data. As we learned from our measures, we customized them to align with all of our processes. This article describes the journey of measuring Quality Assurance and Toxicology, including highlights of implementation strategies and lessons learned along the way. PMID:7804620

    Interprofessional education and ethics education are two educational programs that blend together well, and, moreover, they are a natural fit for teaching in an academic health science center. The purpose of this paper is to describe our recent journey of developing and implementing an interprofessional ethics curriculum across the six schools of UTHealth. We provide an overview of the goals of the Campus-wide Ethics Program, which is housed in the McGovern Center for Humanities and Ethics, and we highlight certain innovative developments that are the result of the collaborative work of faculty and administrators from all six schools of UTHealth. In addition, a brief synopsis of the specific didactic and clinical courses in which ethics is a significant component is outlined for both the dental and the dental hygiene curricula. Lastly, we describe some of the recent scholarly activities that are a product of this new program. We are excited about our evolving efforts and the potential benefits of weaving interprofessional ethics within our school and across our campus. This article tells the story of our journey beyond "the silos" that are common among academic health science centers.

  18. Ambivalent journeys of hope: embryonic stem cell therapy in a clinic in India.

    PubMed

    2015-03-01

    Stem cell therapy in non-Western countries such as India has received a lot of attention. Apart from media reports, there are a number of social science analyses of stem cell policy, therapy, and research, their ethical implications, and impact of advertising on patients. Nevertheless, in the media reports as well as in academic studies, experiences of patients, who undertake overseas journeys for stem cell therapy, have largely been either ignored or presented reductively, often as a "false hope." In this article, I analyze the experiences of patients and their "journeys of hope" to NuTech Mediworld, an embryonic stem cell therapy clinic in New Delhi, India. My analysis, which draws on my observations in the clinic and patients' experiences, instead of seeking to adjudicate whether embryonic stem cell therapy in clinics such as NuTech is right or wrong, true or false, focuses on how patients navigate and contest these concerns. I utilize Gilles Deleuze and Felix Guattari's "concepts," lines of flight and deterritorialization, to highlight how embryonic stem cell therapy's "political economy of hope" embodies deterritorialization of several "regimes of truth" and how these deterritorializations impact patients' experiences.

    Parents are perhaps the best placed individuals to comment upon their child's life story, including early life experiences, transitions and their child's needs. However, research has rarely focussed on the views of parents of young people who have committed serious offences. This research aimed to explore parents' opinions of which factors may have led to their child becoming involved with the criminal justice system. Interviews were undertaken with six parents who were asked to narrate their child's life journey into offending behaviours. The data were then analysed using narrative analysis techniques, and a shared story was created which incorporated the main transitional stages in the children's journeys, as seen by the parents. The findings suggest that it is not just the child but the whole family who have been in a state of distress throughout the child's life. Systemic and environmental factors are argued to contribute to this distress, and the use of diagnosis for this population is critically evaluated. The research highlights a life story in which the child's and family's distress remains unheard and therefore unresolved. Clinical implications for working with this population are discussed.

  20. Brokers, consumers and the internet: how North American consumers navigate their infertility journeys.

    PubMed

    Speier, Amy R

    2011-11-01

    North Americans who suffer infertility often reach an end to treatment options at home, whether it is due to a lack of egg donors in Canada or the high cost of treatment in the USA. Patients navigate their way onto the internet, seeking support and other options. As women and couples 'do the research' online, they conduct endless Google searches, come across IVF brokers, join support groups, read blogs and meet others on the road of infertility. This paper considers the journeys that North American patients make to clinics in Moravia, Czech Republic. Along these travels, patients engage with support groups, other patients, IVF brokers and clinic co-ordinators. Since the distance travelled between North America and Europe is extensive, reproductive travels may be arranged by clinical staff, travel brokers and patients. Acting as consumers, North Americans make different 'choices' along their journeys – the use of a broker, if and when they should join online communities, which clinic to visit and where to stay. This study focuses on the question of how patient choices often determine the success of brokers and clinics, thus influencing the structure of cross-border reproductive care in the Czech Republic.

  1. A mosquito sperm's journey from male ejaculate to egg: Mechanisms, molecules, and methods for exploration†

    Degner, Ethan C.; Harrington, Laura C.

    2016-01-01

    SUMMARY The fate of mosquito sperm in the female reproductive tract has been addressed sporadically and incompletely, resulting in significant gaps in our understanding of sperm-female interactions that ultimately lead to fertilization. As with other Diptera, mosquito sperm have a complex journey to their ultimate destination, the egg. After copulation, sperm spend a short time at the site of insemination where they are hyperactivated and quickly congregate near the entrance of the spermathecal ducts. Within minutes, they travel up the narrow ducts to the spermathecae, likely through the combined efforts of female transport and sperm locomotion. The female nourishes sperm and maintains them in these permanent storage organs for her entire life. When she is ready, the female coordinates the release of sperm with ovulation, and the descending egg is fertilized. Although this process has been well studied via microscopy, many questions remain regarding the molecular processes that coordinate sperm motility, movement through the reproductive tract, maintenance, and usage. In this review, we describe the current understanding of a mosquito sperm's journey to the egg, highlighting gaps in our knowledge of mosquito reproductive biology. Where insufficient information is available in mosquitoes, we describe analogous processes in other organisms, such as Drosophila melanogaster, as a basis for comparison, and we suggest future areas of research that will illuminate how sperm successfully traverse the female reproductive tract. Such studies may yield molecular targets that could be manipulated to control populations of vector species. This article is protected by copyright. All rights reserved PMID:27147424

    Introduction: Helping mothers who have children with autism spectrum disorders requires understanding of their lived experiences. This study aims to uncover the spiritual journey as a main theme in Iranian mothers’ experiences. Method: This hermeneutic phenomenological study is a part of a larger study undertaken for partial fulfillment of the requirement for PhD dissertation in nursing. The main study was performed on 18 cases of Iranian mothers, with experience of caring for a child with an autism spectrum during 2011-2012. They were selected based on purposeful sampling method. Semi -structured interviews for data collection were used. Data analyses were done with the interpretative method. Results: Spiritual journey is one of the main themes of the phenomenon under study in the original project. It consists of three sub -themes each of which supported by a number of common meaning. The sub-themes and their common meanings in parenthesis are (1) Descent: wondering between what is and what will be (having sorrowful tale, unanswered question, escaping from reality, losing hope) (2) Connecting to deity: reflection on the failure in her struggle (gratefulness, surrendering to god, having the divine test) (3) Ascent: helping her child is becoming all of the mother’s life (to rescue, being hopeful, listening to her inner voice). Conclusion: This research concluded that caring for the autistic children led mothers’ lives to raise spirituality and enabled them to help their children and themselves, to grow and be refined in this process.

    2005-01-01

    Journey-time exposures represent an important, though as yet little-studied, component of human exposure to traffic-related air pollution, potentially with important health effects. Methods for assessing journey-time exposures, either as part of epidemiological studies or for policy assessment, are, however, poorly developed. This paper describes the development and testing of a GIS-based system for modeling human journey-time exposures to traffic-related air pollution: STEMS (Space-Time Exposure Modeling System). The model integrates data on source activity, pollutant dispersion, and travel behavior to derive individual- or group-level exposure measures to atmospheric pollution. The model, which is designed to simulate exposures of people as they move through a changing air pollution field, was developed, validated, and trialed in Northampton, UK. The system currently uses ArcInfo to couple four separate submodels: a source activity/emission model (SATURN), a proprietary atmospheric dispersion model (ADMS-Urban), an empirically derived background air pollution model, and a purposely designed time-activity-based exposure model (TOTEM). This paper describes the structure of the modeling system; presents results of field calibration, validation, and sensitivity analysis; and illustrates the use of the model to analyze journey-time exposures of schoolchildren.

    Teaching high school students about the digestive system can be a challenge for a teacher when s/he wants to overcome rote learning of facts without a deeper understanding of the physiological processes inside the alimentary tract. A series of model experiments illustrating the journey of a sandwich was introduced into teaching high school…

  16. Female and male Hispanic students majoring in science or engineering: Their stories describing their educational journeys

    NASA Astrophysics Data System (ADS)

    Brown, Susan Wightman

    National statistics clearly demonstrate an underrepresentation of minorities in the fields of science and engineering. Blacks, Hispanics, American Indians, and Asians do not typically choose science or engineering as their college major; therefore, there is a very small representation of these minorities in the science and engineering labor force. The decision not to major in science and engineering may begin as soon as the child can begin to recognize role models in the media. News stories, magazine articles, television programs, teachers, parents, administrators, and other agencies have painted the picture of a scientist or engineer as being dominantly a White male. Schools have continued society's portrayal by using curriculum, textbooks, role models, instructional strategies, and counseling that continues to encourage the White male to succeed in science and engineering, but discourages the minority students, male and female, from succeeding in these fields. In this qualitative study, 22 Hispanic students, 12 female and 10 male, who are majoring in science or engineering, were interviewed using Seidman's in-depth interviewing technique. These students were shadowed in their college science or engineering classes; their high school and college transcripts were analyzed; and, a focus group was brought together at the end of the interviewing process in order to allow interaction between the participants. The goal was to explore the educational journeys of the 22 Hispanic students. What made a difference in the journeys of these 22 students so that they could succeed in majors that have historically discouraged minority students? Seven themes emerged: family support, honors program, challenging and interactive curriculum, college preparation in high school courses, caring and kind teachers, small class size, and small communities. Gender comparison of the educational journeys documents these differences between the females and males: college preparation, mentoring

    Pan paniscus is unique in the group of African apes because of its range south of the Congo River. Examination of the bio-geographical journey of the genus Pan to the species P. paniscus is important when discussing the evolution of African apes. This paper is a review of the paleo-geographic events, the zoogeography, and faunal sorting which influenced P. paniscus divergence from the Proto-pan ancestor within the recent Miocene through Pliocene Epochs, approximately 10-2 MYA. Finally, by elucidating modern day evidence of food plant forms in the southern periphery exploited by P. paniscus in the forest/savanna mosaic habitat, we are able to conclude with those extrinsic events that most influenced the occurrence and distribution of P. paniscus.

    Faculty shortages in the study of low-incidence sensory disabilities (deafness, blindness, deaf-blindness) constitute personnel preparation challenges, as documented by a variety of organizations. To alleviate this deficit in the low-incidence sensory disability professoriat, the National Leadership Consortium for Sensory Disabilities (NLCSD) was created to support the preparation of preservice researchers in these disciplines. This qualitative study documents the emerging perceptions of research by deafness-focused NLCSD first-year doctoral Fellows during their participation in an online enrichment seminar. Thematic analysis of the online interactions of the Fellows reveals their initial steps in their journey from consumers to producers of research. Results of the study offer insight into the preparation process of leadership personnel in deaf education. PMID:25051883

    The focus of the majority of the psychosocial transplant literature is on post-transplant outcomes, but the transplant journey starts much earlier than this, at the point when transplantation is first considered and a referral for transplant evaluation is made. In this review, we cover information regarding the meaning of the referral process for solid organ transplantation. We discuss various factors of the referral for transplantation including the impact of referral on the pediatric patient and the family, potential expectations and misconceptions held by pediatric patients and parents, the role of health literacy, decision-making factors, and the informational needs of pediatric patients and parents. We elucidate steps that providers can take to enhance transplant referral and provide suggestions for much needed research within this area. PMID:24438194

    This report documents a journey “from research to an approved standard” of a NIST-led standard development activity. That standard, Core Manufacturing Simulation Data (CMSD) information model, provides neutral structures for the efficient exchange of manufacturing data in a simulation environment. The model was standardized under the auspices of the international Simulation Interoperability Standards Organization (SISO). NIST started the research in 2001 and initiated the standardization effort in 2004. The CMSD standard was published in two SISO Products. In the first Product, the information model was defined in the Unified Modeling Language (UML) and published in 2010 as SISO-STD-008-2010. In the second Product, the information model was defined in Extensible Markup Language (XML) and published in 2013 as SISO-STD-008-01-2012. Both SISO-STD-008-2010 and SISO-STD-008-01-2012 are intended to be used together. PMID:26958450

    In Arabidopsis, leaves contribute to the largest part of the aboveground biomass. In these organs, light is captured and converted into chemical energy, which plants use to grow and complete their life cycle. Leaves emerge as a small pool of cells at the vegetative shoot apical meristem and develop into planar, complex organs through different interconnected cellular events. Over the last decade, numerous phenotyping techniques have been developed to visualize and quantify leaf size and growth, leading to the identification of numerous genes that contribute to the final size of leaves. In this review, we will start at the Arabidopsis rosette level and gradually zoom in from a macroscopic view on leaf growth to a microscopic and molecular view. Along this journey, we describe different techniques that have been key to identify important events during leaf development and discuss approaches that will further help unraveling the complex cellular and molecular mechanisms that underlie leaf growth.

    The journey in search for the Higgs boson with the ATLAS and CMS experiments at the Large Hadron Collider (LHC) at CERN started more than two decades ago. But the first discussions motivating the LHC project dream date back even further into the 1980s. This article will recall some of these early historical considerations, mention some of the LHC machine milestones and achievements, focus as an example of a technological challenge on the unique ATLAS superconducting magnet system, and then give an account of the physics results so far, leading to, and featuring particularly, the Higgs boson results, and sketching finally prospects for the future. With its emphasis on the ATLAS experiment it is complementary to the preceding article by Tejinder S. Virdee which focused on the CMS experiment.

    Advances in medical knowledge and care have extended the lives of children with profound and multiple disabilities. In most cases it is the parents who meet the often complex and continual needs of their child with disabilities in their own home. This study explored the experience of support in the lives of such parents. The interpretive, hermeneutic phenomenology of Heidegger was employed to create a detailed and authentic account of the parents' experiences of support. Five interrelated themes emerged from data from in-depth interviews with six parents randomly selected from a purposive sample in a special school setting. The themes were: parents' feelings about support, the journey to accepting support, support as a loss, disability and the parent and the supportive relationship. Understanding the experience of support from the parent's perspective may lead to a consideration of flexible systems that challenge practice to ensure that supporters listen, learn, develop and deliver support in ways that are helpful.

    Summary Recent advances in nanoparticle technology have enabled the fabrication of nanoparticle classes with unique size, shape, and materials, which in turn has facilitated major advancements in the field of nanomedicine. More specifically, in the last decade, nanoscientists have recognized that nanomedicine exhibits a highly engineerable nature that makes it a mainstream scientific discipline, which is governed by its own distinctive principles in terms of interactions with cells and intravascular, transvascular and interstitial transport. This review focuses on recent developments and understanding of the relation between the shape of a nanoparticle and its navigation through different biological processes. Importantly, we seek to illustrate that the shape of a nanoparticle can govern its in vivo journey and destination dictating its biodistribution, intravascular and transvascular transport, and ultimately targeting of difficult-to-reach cancer sites.

    In late 1994, the U.S. Department of Energy (Nevada Operations Office) made a $199,708 grant (through the Mathematics, Science, and Technology Education Program), to the UNFINISHED JOURNEY Project. The Project began in April, 1994, to develop and implement an innovative model of student outreach by San Jose State University (SJSU) to underserved, underrepresented student populations of the East Side Union High School District (ESUHSD). The Project was formed by a consortium involving SJSU, ESUHSD, some 20 private sector organizations (foundations/corporations), numerous local community/professional organizations, and approximately 100 private funders. This proposal to the U.S. Department of Energy was to have the Department join this unique partnership to focus University outreach to underserved student populations to pursue careers in mathematics, science, and technology.

    Academician O. Gazenko, Chief of the Institute of Biomedical Problems, USSR Ministry of Public Health, reviewed the short but intense history of Soviet research in space biology and medicine. The solid academic approach of the Soviet Academy of Sciences in giving a good start at the very beginning of the space age is stressed and key people and institutions who initiated these studies are named. The basic feature of the first period of space biology is seen as the search for answers to a few fundamental questions of survival in space. It is pointed out that the initiated investigations were replaced by refined, in-depth studies of the biological, biophysical, and biochemical processes in human organism in the space environment and the search for methods which should enable cosmonaut crews to live in space for several years during interplanetary journeys. Discussing the typical problems of this effort, Gazenko each time showed how they benefit medical science and practice in general.

    Mackenbach, Johan

    2005-01-01

    This essay reviews some of the sources of idealism in public health, on the basis of an intellectual journey to Kos (home to Hippocrates and his altruistic legacy), Dresden (where the Deutsches Hygiene Museum illustrates the historical connections between fascism and public health), and Utopia (exemplified by Etienne Cabet's Icarie, a fantasy of an ideal city which has nevertheless been partly realized). It is suggested that the large-scale altruism of public health has to be balanced with the value of individual autonomy, and that some degree of dreaming of a better and healthier world is indispensable for further progress in public health. The main conclusion is that the ethical foundations of public health are not always self-evident, and that critical reflection on these foundations was, is, and will always be necessary.

    We report on a 14-year-old Arabian girl who suddenly developed coughing after having aspirated a needle used for fixing her headscarf. The chest X-ray showed the needle located in the right main bronchus. However, subsequent flexible bronchoscopy could not detect any foreign body. A further X-ray of the abdomen showed the needle now behind the diaphragm. Gastro-oesophageal endoscopy was also uneventful. On the third day, the needle was excreted naturally. Astonishingly, this journey of the wandering needle from bronchus to intestine was not realised by the patient at any time. Our case highlights that children and adolescents should be warned repeatedly about the risks of putting needles between their teeth. It also reminds the physician to diagnose aspirated foreign bodies as early as possible to prevent wandering and migrating, which may induce new risks and unnecessary diagnostic and therapeutic procedures.

    When a child has chronic pain, it affects the parents. Their response and how it is factored into their lives and family function was the phenomenon of interest that drove this study. The available literature was sparse, especially when the pain etiology was neuropathic. The purpose of this study was to describe the parents' perception of the pain journey from the initial occurrence of their child's pain through the labyrinth of treatment options to successful outcome, to gain a better understanding of parental beliefs about pain, and to learn how parental attitudes and behaviors relate to children's response to treatment for chronic pain. Qualitative descriptive design was used to better understand the phenomenon from those who were the experts because they had experienced it. Parents whose child was enrolled in a pain rehabilitation program participated in open-ended interviews. The children/adolescents were 8-18 years old and diagnosed with complex regional pain syndrome or a related chronic pain condition. During data immersion, the investigators uncovered the pervasive underlying themes of suffering and disempowerment. In addition, the multiple meaning elements were grouped into three categories and supportive subcategories labeled as follows: parent distress, with subcategories schism in parenting, searching, and disabled parenting; and lack of control, with the subcategories family/community, fear, and empowerment. The voices of parents were heard in their description of the exhausting and difficult journey in search of pain relief for their child. Their comments provided insight into how they defined the child's pain and their related parental role.

    The European Space Agency’s SMART-1 was one of three payloads on Ariane Flight 162. The generic Ariane-5 lifted off from the Guiana Space Centre, Europe’s spaceport at Kourou, French Guiana, at 2014 hrs local time (2314 hrs GMT) on 27 September (01:14 Central European Summer time on 28 September). 42 minutes after launch, SMART-1 as last of the three satellites had been successfully released into a geostationary transfer orbit (654 x 35 885 km, inclined at 7 degrees to the Equator). While the other two satellites are due to manoeuvre towards geostationary orbit, the 367 kg SMART-1 will begin a much longer journey to a target ten times more distant than the geostationary orbit: the Moon. “Europe can be proud”, said ESA Director General Jean-Jacques Dordain, after witnessing the launch from ESA’s ESOC space operations centre in Darmstadt, Germany, “we have set course for the Moon again. And this is only the beginning: we are preparing to reach much further”. The spacecraft has deployed its solar arrays and is currently undergoing initial checkout of its systems under control from ESA/ESOC. This checkout will continue until 4 October and will include with the initial firing of SMART-1’s innovative ion engine. By ion drive to the Moon “Science and technology go hand in hand in this exciting mission to the Moon. The Earth and Moon have over 4 thousand million years of shared history, so knowing the Moon better will help scientists in Europe and all over the world to better understand our planet and will give them valuable new hints on how to better safeguard it” said ESA Director of Science David Southwood, following the launch from Kourou. As the first mission in the new series of Small Missions for Advanced Research in Technology, SMART-1 is mainly designed to demonstrate innovative and key technologies for future deep space science missions. The first technology to be demonstrated on SMART-1 will be Solar Electric Primary Propulsion (SEPP), a

    The effects of floor space on the trailer and journey time during transport from the farm to the packing plant on indicators of stress (open-mouth breathing, muscle tremors, and skin discoloration) and on the incidence of transport losses (dead on arrival, nonambulatory, noninjured, and nonambulatory, injured) were evaluated in a study involving 160 loads of market-weight pigs (BW 124.7 ± 4.38 kg) using a split-plot design with a 2 × 6 factorial arrangement of treatments: 1) journey time [main plot; short (<1 h) and long (3 h)] and 2) floor space (subplot; 0.396, 0.415, 0.437, 0.462, 0.489, and 0.520 m(2)/pig, which is equivalent to 0.317, 0.332, 0.350, 0.370, 0.391, and 0.416 m(2)/100 kg of BW, respectively). Two consecutively loaded trailers were randomly allotted to journey time treatment. Floor space treatments were compared in the front 3 compartments on the top and bottom decks of the trailer and were created by varying the number of pigs per compartment, which confounds the effect of floor space with group size. Of the 17,652 pigs transported in 954 test compartments, 0.24% died or became nonambulatory. Neither journey time nor floor space had an effect (P > 0.05) on the incidence of dead and nonambulatory, injured pigs, or on total transport losses. There were interactions (P < 0.05) between journey time and floor space treatments for the incidences of nonambulatory, noninjured pigs and open-mouth breathing. For 2 of the smallest floor spaces (0.415 and 0.437 m(2)/pig), the incidence of nonambulatory, noninjured pigs was greater on short than on long journeys; for the other 4 floor spaces there was no effect (P > 0.05) of journey time. The incidence of open-mouth breathing for the 3 smallest floor spaces was greater (P < 0.05) for short than long journeys, whereas there was no effect (P > 0.05) of journey time for the 3 greatest floor spaces. The frequency of skin discoloration was greater (P < 0.001) for pigs transported at the 2 smallest floor spaces

    2014-01-01

    Background Antibacterial overuse, misuse and resistance have become a major global threat. The Joint Commission International (JCI) accreditation standards include quality improvement and patient safety, which is exemplified by antimicrobial stewardship. There are currently few reports on interventions to improve the quality of outpatient antibacterial prescribing. Methods A before-after intervention study, aiming at antibacterial use in outpatients, was performed in a university-affiliated hospital with 2.8 million outpatient visits annually during the journey to JCI accreditation (March of 2012 - March of 2013). Comprehensive intervention measures included formulary adjustment, classification management, motivational, information technological, educational and organizational measures. A defined daily dose (DDD) methodology was applied. Pharmacoeconomic data and drug-related problems (DRPs) were statistically compared between the two phases. Results The variety of antibacterials available in outpatient pharmacy decreased from 38 to 16. The proportion of antibacterial prescriptions significantly decreased (12.7% versus 9.9%, P < 0.01). The proportion of prescriptions containing the restricted antibacterials was 30.4% in the second phase, significantly lower than the value of 44.7% in the first phase (P < 0.01). The overall proportion of oral versus all antibacterial prescriptions increased (94.0% to 100%, P < 0.01) when measured as defined daily doses. Statistically significant increases in relative percentage of DDDs of oral antibacterials (i.e., DDDs of individual oral antibacterial divided by the sum of DDDs of all antibacterials) were observed with moxifloxacin, levofloxacin, cefuroxime axetil, ornidazole, clindamycin palmitate, cefaclor, amoxicillin and clarithromycin. Occurrence rate of DRPs decreased from 13.6% to 4.0% (P < 0.01), with a larger decrease seen in surgical clinics (surgical: 19.5% versus 5.6%; internal medicine: 8.4% versus 2

    All engineering fields experience growth, from early trial & error approaches, to disciplined approaches based on fundamental understanding. The field of software engineering is making the long and arduous journey, accomplished by evolution of thinking in many dimensions. This paper takes the reader along a trio of simultaneous evolutionary paths. First, the reader experiences evolution from a zero-risk mindset to a managed-risk mindset. Along this path, the reader observes three generations of security risk management and their implications for software system assurance. Next is a growth path from separate surety disciplines to an integrated systems surety approach. On the way, the reader visits safety, security, and dependability disciplines and peers into a future vision which coalesces them. The third and final evolutionary path explored here transitions the software engineering field from best practices to fundamental understanding. Along this road, the reader observes a framework for developing a {open_quotes}science behind the engineering{close_quotes}, and methodologies for software surety analysis.

    Writing for self-discovery begins on the first day of class and continues throughout the semester. Class introduction compares this journey to flying an airplane, requiring adjustments to successfully reach the destination. A systems framework promotes writing-to-learn and writing as a self-discovery tool for graduate nursing administration students in this clinical preceptorship. Because writing-to-learn is an unfamiliar concept for many students, the process is incorporated into the self-evaluation tools of writing discovery and intention statements, keeping a clinical learning log, reflective questioning, and feedback strategies. The purpose is to foster the critical administrative processes of writing, thinking, analyzing, and synthesizing. Written instructor feedback probes the relationships between concepts and their relationships with students' learning. Future strategies will include additional formative and summative self-evaluative tools, including videotaping, to foster awareness of self in a written format for both students and instructor. The goal is to prepare master's graduates who are creative thinkers, self-evaluators, and analytical writers for service in clinical and administrative settings.

    2013-10-15

    Material cycles have become increasingly coupled and interconnected in a globalizing era. While material flow analysis (MFA) has been widely used to characterize stocks and flows along technological life cycle within a specific geographical area, trade networks among individual cycles have remained largely unexplored. Here we developed a trade-linked multilevel MFA model to map the contemporary global journey of anthropogenic aluminum. We demonstrate that the anthropogenic aluminum cycle depends substantially on international trade of aluminum in all forms and becomes highly interconnected in nature. While the Southern hemisphere is the main primary resource supplier, aluminum production and consumption concentrate in the Northern hemisphere, where we also find the largest potential for recycling. The more developed countries tend to have a substantial and increasing presence throughout the stages after bauxite refining and possess highly consumption-based cycles, thus maintaining advantages both economically and environmentally. A small group of countries plays a key role in the global redistribution of aluminum and in the connectivity of the network, which may render some countries vulnerable to supply disruption. The model provides potential insights to inform government and industry policies in resource criticality, supply chain security, value chain management, and cross-boundary environmental impacts mitigation.

    Over the past 5 years, general practice in the UK has undergone major change. Starting with the introduction of the new GMS contract in 2004, it has continued apace with the establishment of Postgraduate Medical Education Training Board, a GP training curriculum, and nMRCGP. The NHS is developing very differently in the four countries of the UK. Regulation of the profession is under review, and a system of relicensing, recertification, and revalidation is being introduced. The Essence project, initiated by RCGP Scotland in conjunction with International Futures Forum 4 years ago is a constructive response to these changes. It has included learning journeys, a discussion day for GPs, and commissioned short pieces of 100 words from GPs and patients. From an analysis of these, some characteristics of the essence of general practice have been defined. These include key roles and core personal qualities for GPs. It is argued that general practice has important and unique advantages - trust, coordination, continuity, flexibility, universal coverage, and leadership - which mean that it should continue to be central to the development of primary care throughout the UK.

    2016-01-01

    RNA interference (RNAi) is an evolutionary conserved highly specific gene-silencing mechanism initiated by small interfering RNA (siRNA) molecules. Fast-paced preclinical and clinical studies helped the siRNA technology become an efficient tool for undruggable targets in different diseases including genetic diseases, viral diseases and cancer. Despite great feature of siRNAs that can down-regulate any protein in the cells, the full potential and the success of the preclinical studies could not be translated into largely successful clinical outcomes. It has become clear that the possibility of overcoming the pitfalls for in vivo siRNA therapy fully depends on delivery systems. In this review, we start with the challenges and barriers for in vivo siRNA delivery. Then we briefly discuss the recent developments in siRNA modification technology. We specifically focused on siRNA lipidation and delivery approaches with special emphasis on the lipid based hybrid systems. Here we summarize the journey of lipid-based micelle-like nanoparticle systems that combine longevity in blood, effective cellular uptake and endosomal escape for successful siRNA delivery and discuss the multifunctional stimuli-sensitive systems based on lipids as the next generation smart systems.

    The Augsburg physician Leonhard Rauwolf is known to the history of Western sciences for "discovering" the exotic flora of the Near East. This article deals with the social background of his studies in Germany and France and his perception of foreign lands, plants, and peoples. Before Rauwolf started his journey at Marseille in 1573 he had received a proper education in practical botany at Montpellier under Guillaume Rondelet. He had also collected about 600 specimens of plants in his herbarium. According to the common medical conventions of his time--most prominently represented by the Renaissance anatomist Andreas Vesalius--in his travel account Rauwolf claimed to tell only what he had seen, experienced, observed by himself, or touched with his own hands. Contrary to his own claim of pure "autopsy", or direct experience, however, Rauwolf's Aigentliche Beschreibung [Actual Description] was composed from different sources. As previously unnoted manuscript letters from the Trew-collection at the University Library of Erlangen show, editorial work on Rauwolf's book was a lengthy process. The final composition ended up drawing on such different sources as the Old and New Testament, ancient natural philosophy, Christian travel literature and sermons, more recent botanical books, oral information from other academics, fellow travellers or indigenous people, and--finally--Rauwolf's own mpressions and observations.

    The field of anatomy, one of the most ancient sciences, first evolved in Egypt. From the Early Dynastic Period (3100 BC) until the time of Galen at the end of the 2nd century ad, Egypt was the center of anatomical knowledge, including neuroanatomy. Knowledge of neuroanatomy first became important so that sacred rituals could be performed by ancient Egyptian embalmers during mummification procedures. Later, neuroanatomy became a science to be studied by wise men at the ancient temple of Memphis. As religious conflicts developed, the study of the human body became restricted. Myths started to replace scientific research, squelching further exploration of the human body until Alexander the Great founded the city of Alexandria. This period witnessed a revolution in the study of anatomy and functional anatomy. Herophilus of Chalcedon, Erasistratus of Chios, Rufus of Ephesus, and Galen of Pergamon were prominent physicians who studied at the medical school of Alexandria and contributed greatly to knowledge about the anatomy of the skull base. After the Royal Library of Alexandria was burned and laws were passed prohibiting human dissections based on religious and cultural factors, knowledge of human skull base anatomy plateaued for almost 1500 years. In this article the authors consider the beginning of this journey, from the earliest descriptions of skull base anatomy to the establishment of basic skull base anatomy in ancient Egypt.

    Besides growing plants, eating a lot, and drinking beer, Tolkien's Hobbits enjoy maintaining a quiet state. Regarding the latter, the name chosen for a recently discovered transcription factor seems to be unintentionally appropriate. The zinc finger protein ZNF683 was originally named "Hobit" for Homolog of Blimp-1 in T cells. In this issue of the European Journal of Immunology, Braga et al. [Eur. J. Immunol. 2015. 45: 2945-2958] demonstrate that in humans, Hobit is almost exclusively expressed in effector T cells, in particular in quiescent and long-lived effector-type CD8(+) T cells. Hobit may initially appear as another "player" in the quest for transcription factors guiding T-cell differentiation; the discoveries of T-bet, Eomes, Blimp-1, and others have significantly contributed to our understanding of how this process is tightly regulated. However, Hobit may be special--the currently available results suggest substantial differences in Hobit's regulatory functions between mice and humans, such as expression patterns and IFN-γ regulation. And it may turn out that Hobit's function in human T cells is highly adapted to lifelong, periodic challenges with varying, physiological doses of pathogens. Thus, the new study about Hobit in human T cells may be the beginning of a long journey.

  5. Insiders or outsiders? Mental health service users' journeys towards full citizenship.

    The present study explores the journeys towards full citizenship for those using mental health services as they lobbied to be included as full citizens with the same rights and responsibilities as others in society. Qualitative data were collected through semistructured interviews with 17 service users, five government representatives, and seven registered mental health nurses. A conceptual framework of citizenship containing four domains - the extent, content, depth and acts of citizenship - was used to analyse the data. This paper reports the findings from the service users' data in the first domain, the extent of citizenship, defined as the rules and norms of inclusion and exclusion. The degree to which the service user participants were accepted as full citizens with the same civil, political, and social rights as others was contingent on their ability to adopt their society's rules and norms and appear as 'normal' citizens. Participants often experienced being 'othered' and excluded from the many rights and responsibilities of citizenship due to society's perception that service users lack certain attributes of normal, productive citizens. Participants reported that being labelled with a mental illness led to them being marginalized and ostracized, thus placing conditions and barriers on their citizenship status. Findings show that in response to experiencing conditional citizenship, participants shaped their behaviour to assimilate with other citizens. As well, they engaged in practices of inclusion to challenge and broaden the social rules and norms in order to be accepted without disavowing their differences.

  6. A journey to citizenship: constructions of citizenship and identity in the British Citizenship Test.

    The British Citizenship Test was introduced in 2005 as one of a raft of new procedures aimed at addressing the perceived problems of integration and social cohesion in migrant communities. In this study, we argue that this new citizenship procedure signals a shift in British political discourse about citizenship - particularly, the institutionalization of a common British citizen identity that is intended to draw citizens together in a new form of political/national community. In line with this, we examine the British Citizenship Test from a social psychological perspective to interrogate the ways in which the test constitutes identity, constitutes citizenship, and constitutes citizenship-as-identity. Analysis of the test and its associated documents highlights three ways in which Britishness-as-identity is constituted, that is, as a collective identity, as a superordinate and national identity, and finally as both a destination and a journey. These findings are discussed in terms of their implications for models of citizenship and models of identity.

    2015-09-01

    This paper discusses the development of a mental health nurse clinician to a mental health nurse researcher. Understanding the theoretical and professional drives that shape mental health nurses clinical practice and how that links to becoming a researcher is discussed. Mental health nurses who conduct research have to often move between their clinical roles and that of the researcher, doing this safely using a reflective supervision approach enables the nurse to conduct the research from a stronger professional and ethical standpoint. The intention of the paper is to encourage mental health nurses to engage in research and development. Shifting between the positions of a mental health nurse clinician and a qualitative researcher has some parallels to the processes in the nurse-service user relationship. This paper addresses this development from practitioner to researcher in one mental health nurse's journey through a PhD study using constructivist grounded theory. The paper examines theoretical and professional drives that have shaped my clinical practice and the role of the researcher in constructivist grounded theory, the notion of the researcher shifting between insider and outsider status, and the importance of reflexivity in conducting research. These influences will be discussed in the context of the development of a constructivist grounded theory study of the delivery of health care to service users with a mental illness in general hospital wards.

    Long-distance travel is becoming increasingly common. Whatever the means of transport, any long journey will be associated with "travel fatigue". The symptoms associated with this phenomenon result from a changed routine (particularly sleep lost and meals) and the general disruption caused by travel. Planning any trip well in advance will minimise many of these problems, but some factors are less easy to guard against. These problems include sitting in cramped and uncomfortable conditions and, with flights, the hypoxic environment in the cabin. After arrival at the destination in another country, there can be problems coping with the local language, alterations in food and different customs. If the flight has crossed the equator, then there is likely to be a change in season and natural lighting and, if it has crossed several time zones, there will also be the problem of "jet lag", caused by a transient desynchrony between the "body clock" and the new local time. Moreover, the new environment might differ from the place of departure with regard to ambient temperature and humidity, altitude, natural lighting (including ultraviolet radiation) and pollution. The traveller needs to be aware of these changes before setting off, so that appropriate preparations (clothing, for example) can be made. PMID:19237142

    This study reports a subset of findings from a larger, ongoing study aimed at exploring interactions between teacher identity, learning, and classroom practices in a social justice teacher education program at a selective liberal arts college in New York. This case-study explores the journey of Elena, as an immigrant, a student, and a pre-service teacher candidate towards becoming a social justice educator. Elena reflects upon her school language experiences as an immigrant youth, her learning in a social justice teacher education program, and her field experiences in an international high school. The analysis spans macro-, meso-, and microlevels to explore the ways globalization, particularly immigration, as well as schooling policies for English language learners interact with aspects of Elena's core identity, particularly in school settings. The findings show some of the ways language and literacy verified and/or denied aspects of Elena's core identity; specific instances where second language proficiency was cast as power and privilege versus disadvantage according to ethnic, language, and class categorizations; and the struggles Elena, and other immigrant youth may face given the focus on English language acquisition and high stakes accountability in schools, at the expense of students' primary language proficiency and affirmation of core identity markers.

    The regulated secretory pathway begins with the formation of secretory granules by budding from the Golgi apparatus and ends by their fusion with the plasma membrane leading to the release of their content into the extracellular space, generally following a rise in cytosolic calcium. Generation of these membrane-bound transport carriers can be classified into three steps: (i) cargo sorting that segregates the cargo from resident proteins of the Golgi apparatus, (ii) membrane budding that encloses the cargo and depends on the creation of appropriate membrane curvature, and (iii) membrane fission events allowing the nascent carrier to separate from the donor membrane. These secretory vesicles then mature as they are actively transported along microtubules toward the cortical actin network at the cell periphery. The final stage known as regulated exocytosis involves the docking and the priming of the mature granules, necessary for merging of vesicular and plasma membranes, and the subsequent partial or total release of the secretory vesicle content. Here, we review the latest evidence detailing the functional roles played by lipids during secretory granule biogenesis, recruitment, and exocytosis steps. In this review, we highlight evidence supporting the notion that lipids play important functions in secretory vesicle biogenesis, maturation, recruitment, and membrane fusion steps. These effects include regulating various protein distribution and activity, but also directly modulating membrane topology. The challenges ahead to understand the pleiotropic functions of lipids in a secretory granule's journey are also discussed. This article is part of a mini review series on Chromaffin cells (ISCCB Meeting, 2015).

    The Magellan seamounts began forming as large submarine shield volcanoes south of the equator during the Cretaceous. These volcanoes formed as a cluster on the small Pacific plate in a period when tectonic stress was absent. Thermal subsidence of the seafloor led to sinking of these volcanoes and the formation of guyots as the seamounts crossed the equatorial South Pacific (10-0°S) sequentially and ocean surface temperatures became too high for calcareous organisms to survive. Guyot formation was completed between about 59 and 45 Ma and the guyots became phosphatized at about 39-34 and 27-21 Ma. Ferromanganese crusts began formation as proto-crusts on the seamounts and guyots of the Magellan Seamount cluster towards the end of the Cretaceous up to 55 Ma after the formation of the seamounts themselves. The chemical composition of these crusts evolved over time in a series of steps in response to changes in global climate and ocean circulation. The great thickness of these crusts (up to 15-20 cm) reflects their very long period of growth. The high Co contents of the outer parts of the crusts are a consequence of the increasing deep circulation of the ocean and the resulting deepening of the oxygen minimum zone with time. Growth of the Co-rich Mn crusts in the Magellan Seamount cluster can be considered to be the culmination of a long journey through time.

    This paper presents a new approach to science education that takes a path through sociocultural theory and into the ideas of Gloria Anzaldúa. We apply Anzaldúan theory to science education by illustrating it in action through various examples which explore the multidimensionality of teaching science with Latin@ students in various contexts including dual language settings. We present what it is to journey through transformation using examples from educators at various levels of science within the world of teaching science with Latin@ students in the U.S. Our examples illustrate how Latin@ students cross many cultural borders in Spanish, English, Latin@ home culture, school culture, and the world of scientific dialogue and content, and in doing so, go through tensions and transformations between dominant and non-dominant worlds, which should be acknowledged and better understood through Anzaldúan theory. Fundamentally, we present a transformative notion of Latin@ science learning as "living on the bridges" of many dialogic and cultural practices, and having to negotiate these in-between spaces, or " nepantla" (Anzaldúa and Keating in Interviews, Psychology Press, London, 2000), where Latin@ students must contend with the fragmented and sometimes painful struggle of living in racialized reality amidst the demands of a dominant culture, and where transformation and healing are possible through the path of conocimiento. We advocate for teachers to become science teacher nepantler@s, who guide their students through nepantla, and into a new mestiz@ consciousness of science education.

  13. Mapping the global journey of anthropogenic aluminum: a trade-linked multilevel material flow analysis.

    Material cycles have become increasingly coupled and interconnected in a globalizing era. While material flow analysis (MFA) has been widely used to characterize stocks and flows along technological life cycle within a specific geographical area, trade networks among individual cycles have remained largely unexplored. Here we developed a trade-linked multilevel MFA model to map the contemporary global journey of anthropogenic aluminum. We demonstrate that the anthropogenic aluminum cycle depends substantially on international trade of aluminum in all forms and becomes highly interconnected in nature. While the Southern hemisphere is the main primary resource supplier, aluminum production and consumption concentrate in the Northern hemisphere, where we also find the largest potential for recycling. The more developed countries tend to have a substantial and increasing presence throughout the stages after bauxite refining and possess highly consumption-based cycles, thus maintaining advantages both economically and environmentally. A small group of countries plays a key role in the global redistribution of aluminum and in the connectivity of the network, which may render some countries vulnerable to supply disruption. The model provides potential insights to inform government and industry policies in resource criticality, supply chain security, value chain management, and cross-boundary environmental impacts mitigation.

    Palomar Medical Center, like many California healthcare institutions in the 1990s, faced the challenge of needing to meet state building seismic requirements. As a result of the mandate and infrastructure demands that would need to be made to accommodate the new standards, the health system set out to assess the larger needs of the communities served, evaluate the medical and technological changes that would be part of future clinical care delivery systems, and assess our capability to meet the financial impact such changes would have on the organization. This article shares our journey to build a new hospital--one that could be studied by other health systems facing the same or similar challenges. It incorporates elements associated with the concept of "Fable Hospital"--a design promulgated by leading architects and designers from around the world and researched by the Center for Health Design--which considers the use of evidenced-based principles gathered over the past 20 years that, when incorporated, can lead to the creation of buildings that enhance the quality of care, provide safety for patients and staff, and meet the needs of patients and families in meaningful ways. Finally, Palomar Medical Center is an environment that allows for effective, flexible integration of technology and expansion of staff while improving the efficiency of operations that are critical to the management of the hospital in a changing healthcare delivery world.

    In 2002, the American Board of Internal Medicine (ABIM) Foundation launched the Professionalism Charter Project (Putting the Charter into Practice), an effort to more broadly disseminate an international physician charter on professionalism developed in collaboration with the American College of Physicians (ACP) Foundation and the European Federation of Internal Medicine. The Professionalism Charter Project awarded grants to five academic health centers (AHCs) in support of campus initiatives aimed at implementing the charter's commitments to patient welfare, autonomy, and social justice. One of those centers, the University of Texas Medical Branch at Galveston (UTMB), was already deeply involved in a professionalism initiative under the leadership of university president Dr. John Stobo, who had led ABIM's Project Professionalism some years earlier. The authors describe the influence of that initiative on UTMB's professionalism journey, from Stobo's appointment in 1997 to the latest actions undertaken to extend the charter campus-wide, binding all members of the university community to its principles and commitments. They reiterate challenges to professionalism well known to readers of this journal (e.g., the insidious influence of the hidden curriculum) and detail programs undertaken to address those challenges, stressing UTMB's campus-wide approach to interdisciplinary collaboration. Assessment of, and accountability for, professional behavior are key features of UTMB's approach, and particular attention is given to the decisions, circumstances, and programs involved in making the charter relevant, not only to physicians, but to each member of the AHC community. Finally, the authors offer a list of lessons learned along the way.

    The Salish Sea, contained within the United States and British Columbia, Canada, is the homeland of the Coast Salish Peoples and contains a diverse array of marine resources unique to this area that have sustained Coast Salish cultures and traditions for millennia. In July 2009, the Coast Salish People and U.S. Geological Survey conducted a second water quality study of the Salish Sea to examine spatial and temporal variability of environmental conditions of these surface waters as part of the annual Tribal Journey. Six canoes of approximately 100 towed multi parameter water-quality sondes as the Salish People traveled their ancestral waters during the middle of summer. Sea surface temperature, salinity, pH, dissolved oxygen, and turbidity were measured simultaneously at ten-second intervals, and more than 54,000 data points spanning 1,300 kilometers of the Salish Sea were collected. The project also synthesized Coast Salish ecological knowledge and culture with scientific monitoring to better understand and predict the response of coastal habitats and marine resources. Comparisons with data collected in 2008 reveal significantly higher mean surface-water temperatures in most subbasins in 2009 linked to record air temperatures that affected the Pacific Northwest in July 2009. Through large-scale spatial measurements collected each summer, the project helps to identify patterns in summer water quality, areas of water-quality impairment, and trends occurring through time.

    A sustainable society has been said to require knowledge of the limits placed by nature. Whatever one's views on the know-ability and significance of such limits, science strives to improve our understanding of these limiting factors, of which water is recognized to be one of the most important. Despite the centrality of water, the water cycle is maddeningly difficulty to pin down with the level of detail that is desired for resolving issues about the fate of pollutants, nutrient cycling and the global carbon balance, etc. But there is hope lurking in the Swedish landscape. The simplicity of hydrology in many Fennoscandian till soils, combined with applications of the only true tracers of water (isotopes of the water molecule) that were pioneered by Uppsala University hydrologists -provide a hydrological basis for breakthroughs in the biogeochemistry of critical earth support systems. This talk will explore some recent advances in understanding both pollutants and natural cycles, with linkages back to the concepts presented in the Water's Journey from Rain to Stream by Harald Grip and Allan Rodhe. The examples will include the mercury, acidity, and biogenic carbon of relevance to the "aquatic conduit" in the global carbon cycle. The talk will finish with thoughts about where to go next with the power that a well-characterized hydrology can provide.

    Over 30 million people worldwide are currently infected with human immunodeficiency virus type-1 (HIV-1). While HIV-1 infection was initially thought to be a death sentence, the advent of combination antiretroviral therapy (cART) in the mid-1990's resulted in decreases in viremia and an extended lifespan for infected persons. Despite this, long-term control of the virus in the absence of drug therapy has yet to be achieved, owing to the rebound in viral load and resumption of disease progression that follows removal of the patient from cART. Currently, the most promising candidates for an HIV-1 cure are immunotherapies that harness the patient's own immune system and induce cytotoxic T lymphocyte (CTL)-mediated clearance of infected cells. Most of these approaches were developed and optimized in the cancer setting and have had varying degrees of success, the findings from which have wide applications to various disease models. In this review, we evaluate the past successes and failures of cancer immunotherapy and how the findings have shaped our journey toward an HIV-1 cure.

    Long-distance travel, for business or pleasure, is becoming increasingly common.

Planning any trip well in advance will minimise many of these problems, but some factors are less easy to guard against; these include sitting in cramped and uncomfortable conditions and, with flights, the hypoxic environment in the cabin. After arrival at a destination in another country, there can be problems with language, altered food and different customs. If the flight has crossed the equator, then there is also likely to be a change in season and natural lighting, and if the flight has, additionally or alternatively, crossed several time zones, then there will also be the problem of "jet lag", caused by a transient dyssynchrony between the "body clock" and the new local time. The new environment might differ from the place of departure with regard to ambient temperature and humidity, altitude, natural lighting (and hence exposure to ultra-violet radiation) and pollution. In all cases, the traveller needs to be aware of these changes before setting off, so that appropriate preparations (different clothing, for example) can be made.

    In the last decades, the availability of digital user-generated documents from social media has dramatically increased. This massive growth of user-generated content has also affected traditional shopping behaviour. Customers have embraced new communication channels such as microblogs and social networks that enable them not only just to talk with friends and acquaintances about their shopping experience, but also to search for opinions expressed by complete strangers as part of their decision making processes. Uncovering how customers feel about specific products or brands and detecting purchase habits and preferences has traditionally been a costly and highly time-consuming task which involved the use of methods such as focus groups and surveys. However, the new scenario calls for a deep assessment of current market research techniques in order to better interpret and profit from this ever-growing stream of attitudinal data. With this purpose, we present a novel analysis and classification of user-generated content in terms of it belonging to one of the four stages of the Consumer Decision Journey Court et al. (2009) (i.e. the purchase process from the moment when a customer is aware of the existence of the product to the moment when he or she buys, experiences and talks about it). Using a corpus of short texts written in English and Spanish and extracted from different social media, we identify a set of linguistic patterns for each purchase stage that will be then used in a rule-based classifier. Additionally, we use machine learning algorithms to automatically identify business indicators such as the Marketing Mix elements McCarthy and Brogowicz (1981). The classification of the purchase stages achieves an average precision of 74%. The proposed classification of texts depending on the Marketing Mix elements expressed achieved an average precision of 75% for all the elements analysed. PMID:24996448

    2016-01-01

    Although the number of long-term cancer survivors has increased substantially over past years, the journey of survivorship does not always include high-quality, patient-centered care. A variety of survivorship care models have evolved based on who provides this care, the survivor population, the site of care, and/or the capacity for delivering specific services. Other areas of survivorship care being explored include how long follow-up care is needed, application of a risk-based approach to survivorship care, and the role of the survivor in his or her own recovery. However, there is little evidence indicating whether any models improve clinical or patient-reported outcomes. A newer focus in survivorship care has included assessment of potential disparities; the sociodemographic characteristics of population subgroups associated with barriers to receiving high-quality cancer treatment may also affect the survivorship period. Developing policies and programs to address disparities in survivorship care is not simple, and examining how financial hardship affects cancer outcomes, reducing economic barriers to care, and increasing incorporation of patient-centered strategies may be important components. Here too, there is little evidence regarding the best strategies to address these disparities. Barriers to providing high-quality, patient-centered survivorship care include lack of evidence, lack of a trained survivorship workforce, lack of reimbursement structures/insurance coverage, and lack of a health care system that reduces fragmented care. Future research needs to focus on developing a survivorship care evidence base, exploring strategies to facilitate provision of survivorship care, and disseminating best survivorship care practices to diverse and international audiences.

    Understanding the pathogenesis of disease is instrumental in delineating its progression mechanisms and for envisioning ways to counteract it. In the process, animal models represent invaluable tools for identifying disease-related loci and their genetic components. Amongst them, the laboratory rat is used extensively in the study of many conditions and disorders. The Rat Genome Database (RGD—http://rgd.mcw.edu) has been established to house rat genetic, genomic and phenotypic data. Since its inception, it has continually expanded the depth and breadth of its content. Currently, in addition to rat genes, QTLs and strains, RGD houses mouse and human genes and QTLs and offers pertinent associated data, acquired through manual literature curation and imported via pipelines. A collection of controlled vocabularies and ontologies is employed for the standardized extraction and provision of biological data. The vocabularies/ontologies allow the capture of disease and phenotype associations of rat strains and QTLs, as well as disease and pathway associations of rat, human and mouse genes. A suite of tools enables the retrieval, manipulation, viewing and analysis of data. Genes associated with particular conditions or with altered networks underlying disease pathways can be retrieved. Genetic variants in humans or in sequenced rat strains can be searched and compared. Lists of rat strains and species-specific genes and QTLs can be generated for selected ontology terms and then analyzed, downloaded or sent to other tools. From many entry points, data can be accessed and results retrieved. To illustrate, diabetes is used as a case study to initiate and embark upon an exploratory journey. PMID:27602200

    Background The National HIV Reference Laboratory (NHRL) serves as Kenya’s referral HIV laboratory, offering specialised testing and external quality assessment, as well as operating the national HIV serology proficiency scheme. In 2010, the Kenya Ministry of Health established a goal for NHRL to achieve international accreditation. Objectives This study chronicles the journey that NHRL took in pursuit of accreditation, along with the challenges and lessons learned. Methods NHRL participated in the Strengthening Laboratory Management Toward Accreditation (SLMTA) programme from 2010–2011. Improvement projects were undertaken to address gaps in the 12 quality system essentials through development of work plans, team formation, training and mentorship of personnel. Audits were conducted and the scores used to track progress along a five-star grading scale. Standard quality indicators (turn-around time, specimen rejection rates and service interruptions) were measured. Costs of improvement projects and accreditation were estimated based on expenditures. Results NHRL scored 45% (zero stars) at baseline in March 2010 and 95% (five stars) after programme completion in October 2011; in 2013 it became the first public health laboratory in Kenya to attain ISO 15189 accreditation. From 2010–2013, turn-around times decreased by 50% – 95%, specimen rejections decreased by 93% and service interruptions dropped from 15 to zero days. Laboratory expenditures associated with achieving accreditation were approximately US $36 500. Conclusion International accreditation is achievable through SLMTA, even for a laboratory with limited initial quality management systems. Key success factors were dedication to a shared goal, leadership commitment, team formation and effective mentorship. Countries wishing to achieve accreditation must ensure adequate funding and support. PMID:26753130

    Understanding the pathogenesis of disease is instrumental in delineating its progression mechanisms and for envisioning ways to counteract it. In the process, animal models represent invaluable tools for identifying disease-related loci and their genetic components. Amongst them, the laboratory rat is used extensively in the study of many conditions and disorders. The Rat Genome Database (RGD—http://rgd.mcw.edu) has been established to house rat genetic, genomic and phenotypic data. Since its inception, it has continually expanded the depth and breadth of its content. Currently, in addition to rat genes, QTLs and strains, RGD houses mouse and human genes and QTLs and offers pertinent associated data, acquired through manual literature curation and imported via pipelines. A collection of controlled vocabularies and ontologies is employed for the standardized extraction and provision of biological data. The vocabularies/ontologies allow the capture of disease and phenotype associations of rat strains and QTLs, as well as disease and pathway associations of rat, human and mouse genes. A suite of tools enables the retrieval, manipulation, viewing and analysis of data. Genes associated with particular conditions or with altered networks underlying disease pathways can be retrieved. Genetic variants in humans or in sequenced rat strains can be searched and compared. Lists of rat strains and species-specific genes and QTLs can be generated for selected ontology terms and then analyzed, downloaded or sent to other tools. From many entry points, data can be accessed and results retrieved. To illustrate, diabetes is used as a case study to initiate and embark upon an exploratory journey.

    This article documents the findings of a short-term longitudinal study that explored the caring journeys of aged Greek carers providing in-home care for their spouse. Through a deeper understanding of carers' decisions and decision-making and insights from service providers and community leaders, we aimed to inform policy makers, service managers and providers about how to develop and promote culturally appropriate support services, and negotiate them with carers and care recipients in a timely way. Initially, we conducted three focus groups and one follow-up forum with service providers and Greek community leaders. Then, over a 6-month period, we conducted two in-home interviews and two telephone interviews with 12 older Greek carers. We sought to understand factors influencing carers' decision-making regarding service uptake, and we provided information about services as required. Through our thematic analysis, we found that most carers wanted to remain as independent as possible and to avoid forced separation from the one they loved, through institutionalisation. They placed great value on their caring role which, while a struggle at times, gave them a sense of meaning, purpose and belonging. We also found that carers had great resourcefulness, strength and competence. They were all in long-term relationships, had negotiated coming to a foreign country and establishing themselves and were now in the process of negotiating old age and increasing frailty while at the same time providing care and support to family and friends. Our findings suggest that services need to be communicated in ways which support what carers value, not on outdated assumptions about cultural groups, otherwise providers will perpetuate exclusion. We propose an outreach in-home service model with an emphasis on ageing well and staying at home. This model of service provision is a model of care which emphasises relationships and community, and seeks to build social and cultural capital.

    Earth observations are important across the specter of geo-sciences. The Group on Earth Observations (GEO) is coordinating efforts to build a Global Earth Observation System of Systems, or GEOSS. The lack of dedicated funding to support specific Science &Technology activities in support of GEOSS is one of the most important obstacles to engaging the Science &Technology communities in its implementation. Finding resources to outreach and capacity building is likewise a challenge. The continuation of GEO and GEOSS rely on political support which again is influenced by public opinions. The GEO Ministerial Summit in 2014 was an event that both needed visibility and represented an opportunity to mobilize the GEO community in producing outreach and educational material. Through the combined resources from two of GEO tasks in the GEO work plan, a multipurpose educational outreach project was planned and executed. This project addressed the following issues: How can the GEO community mobilize resources for its work plan projects in the Societal Benefit Area Water? How can we produce more educational and capacity building material? How can the GEO community support the GEO secretariat related to public relations (material and otherwise) Based on activities described in the GEO work plan, a showcase video and online campaign consisting on a series of webinars were developed and produced. The video and webinars were linked through a common reference: the water cycle. Various aspects of the water cycle ranging from general to more technical and scientific education were covered in the webinars, while the video called A Modern Explorer's Journey focused on story telling with a more emotional appeal. The video was presented to the Ministers at the GEO Ministerial Summit and distributed widely to the GEO community and through social media and articles (as embedded YouTube and more). A discussion of challenges and successes of this event-based educational outreach project will be

    A journey back in time is possible at the molecular level by reconstructing proteins from extinct organisms. Here we report the reconstruction, based on sequence predicted by phylogenetic analysis, of seven Precambrian thioredoxin enzymes (Trx), dating back between ~1.4 and ~4 billion years (Gyr). The reconstructed enzymes are up to 32° C more stable than modern enzymes and the oldest show significantly higher activity than extant ones at pH 5. We probed their mechanisms of reduction using single-molecule force spectroscopy. From the force-dependency of the rate of reduction of an engineered substrate, we conclude that ancient Trxs utilize chemical mechanisms of reduction similar to those of modern enzymes. While Trx enzymes have maintained their reductase chemistry unchanged, they have adapted over a 4 Gyr time span to the changes in temperature and ocean acidity that characterize the evolution of the global environment from ancient to modern Earth.

    2013-01-01

    Background In the world of today’s of ever-briefer therapies and interventions, people often seem more interested in outcome than process. This paper focuses on the processes used by a multidisciplinary team in the journey from opposition to change to recovery from eating disorders. The approach outlined is most relevant to those with severe and enduring illness. Methods This paper describes a five-phase journey from eating-disorder disability and back to health as it occurs for patients in a community-based facility. This integrative model uses narrative and motivational interviewing counseling weaved into traditional approaches. It approaches illness from a transdiagnostic orientation, addressing the dynamics and needs demanded by the comorbidities and at the same time responding effectively in a way that reduces the influence of the eating disorder. The treatment described involves a five-phase journey: Preliminary phase (choosing a shelter of understanding); Phase 1: from partial recognition to full acknowledgment; Phase 2: from acknowledgment to clear cognitive stance against the eating disorder; Phase 3: towards clear stance against the “patient” status; Phase 4: towards re-authoring life and regaining self-agency; Phase 5: towards recovery and maintenance. Results In a longitudinal study of patients with a severe and debilitating eating disorder treated with this approach. The drop-out rate was less than 10%. This was during the first two months of treatment for those diagnosed with bulimia nervosa, and this was higher than in those diagnosed with anorexia nervosa. At the end of treatment (15 months to 4 years later) 65% of those treated with anorexia nervosa and 81% of those treated with bulimia nervosa were either in a fully recovered state or in much improved. At the four-year follow-up, 68% of those diagnosed with anorexia nervosa and 83% of those diagnosed with bulimia nervosa were categorized as either fully recovered or much improved. All

    Teaching high school students about the digestive system can be a challenge for a teacher when s/he wants to overcome rote learning of facts without a deeper understanding of the physiological processes inside the alimentary tract. A series of model experiments illustrating the journey of a sandwich was introduced into teaching high school biology. Using a computer equipped with a commercially available data-acquisition system and a couple of sensors, it was possible to illustrate the basic underlying physical and chemical principles of digestion to the students. Students were able to investigate, through hands-on activities, the chewing force of the jaws, importance of the mechanical breakdown of food, enzymatic activity of pepsin and amylase, antibacterial activity of hydrochloric acid, and importance of the villi for absorption. Students found the experiments interesting and helpful for understanding the digestive process. Furthermore, the results from testing indicated that the students had a deeper understanding of the physiological processes.

    Australian mental health services have responded to the problem of depression by adopting an early intervention and recovery orientation. Using qualitative research conducted in Australia with 80 women aged 20 to 75 years, we examine how participants invoked particular metaphors to construct meaning about the gendered experience of depression and recovery. We argue that women's stories of recovery provide a rich source of interpretive material to consider the everyday metaphors of recovery beyond clinical notions and linear models of personal change. We identified key metaphors women drew on to articulate the struggle of self-transformation through depression and recovery: the immobilizing effect of depression, recovery as a battle to control depression, and recovery as a journey of self-knowledge. Our findings might be useful for mental health professionals in a range of clinical contexts to reflect on the power of language for shaping how women interpret their experiences of recovery from depression.

    The common law presumption that a boy under the age of 14 is incapable of sexual intercourse has provoked controversial debates in Hong Kong. This article describes a 6-step advocacy journey to examine how community efforts have helped modify this law so that juvenile male sexual offenders under the age of 14 who have committed the crime of having sexual intercourse with underage females can be sentenced to receive appropriate treatment. Seven court cases provided by the magistrates' courts in Hong Kong were used in this advocacy effort for the removal of the presumption in July 2012. Although this effort has yet to reveal signs of effectiveness, it represents greater public awareness about providing rehabilitation appropriate for juvenile sex offenders through a formal sentence. Restorative justice, as opposed to retributive or punitive justice, places an emphasis on rehabilitation of the offender and restoration of victims to a place of wholeness.

  8. Second space Christmas for ESA: Huygens to begin its final journey to Titan/ Media activities.

    2004-12-01

    At 1.25 billion km from Earth, after a 7-year journey through the Solar system, ESA’s Huygens probe is about to separate from the Cassini orbiter to enter a ballistic trajectory toward Titan, the largest and most mysterious moon of Saturn, in order to dive into its atmosphere on 14 January. This will be the first man-made object to explore in-situ this unique environment, whose chemistry is assumed to be very similar to that of the early Earth just before life began, 3.8 billion years ago. The Cassini-Huygens pair, a joint mission conducted by NASA, ESA and the Italian space agency (ASI), was launched into space on 15 October 1997. With the help of several gravity assist manoeuvres during flybys of Venus, Earth and Jupiter, it took almost 7 years for the spacecraft to reach Saturn. The Cassini orbiter, carrying Huygens on its flank, entered an orbit around Saturn on 1 July 2004, and began to investigate the ringed planet and its moons for a mission that will last at least four years. The first distant flyby of Titan took place on 2-3 July 2004. It provided data on Titan's atmosphere which were confirmed by the data obtained during the first close flyby on 26 October 2004 at an altitude of 1174 km. These data were used to validate the entry conditions of the Huygens probe. A second close flyby of Titan by Cassini-Huygens at an altitude of 1200 km is scheduled on 13 December and will provide additional data to further validate the entry conditions of the Huygens probe. On 17 December the orbiter will be placed on a controlled collision course with Titan in order to release Huygens on the proper trajectory, and on 21 December (some dates and times are subject to minor adjustment for operational reasons, except the entry time on 14 January which is know to within an accuracy of under 2 minutes) all systems will be set up for separation and the Huygens timers will be set to wake the probe a few hours before its arrival at Titan. The Huygens probe is due to separate on

    2016-04-01

    Estimation of the adsorbed radiation dose while flight journeys is a complex problem, which should be solved to get correct evaluation of equivalent effective doses and radiation risk assessment. Direct measurements of the adsorbed dose in the aircrafts during regional flights (3-10 hours) has shown that the radiation in the plane may increase 10-15 times (to 2-4 mSv/h) compared to the values on the surface of the Earth (0.2-0.5 mSv/h). Results of instrumental research confirmed by the other investigations. It is a fact that adsorbed doses per year while flight journeys are less than doses from medical tests. However, while flight journeys passengers get the same doses as nuclear power plant staff, people in zones of natural radiation anomalies and so should be evaluated. According to the authors' research, flight journeys are safe enough, when solar activity is normal and if we fly under altitude of 18 km (as usual, while intercontinental flights). Most of people travel by plane not so often, but if flight is lasting in dangerous periods of solar activity (powerful solar winds and magnetic field storms), passengers and flight crew can adsorb great amount of radiation doses. People, who spend more than 500 hours in flight journeys (pilots, business oriented persons', government representatives, etc.) get amount of radiation, which can negatively influence on health and provoke diseases, such as cancer. Authors consider that problem actual and researches are still going on. It is revealed, that radiation can be calculated, using special equations. Great part of radiation depends on very variable outer-space component and less variable solar. Accurate calculations of doses will be possible, when we will take into account all features of radiation distribution (time, season of year and exact time of the day, duration of flight), technical features of aircraft and logistics of flight (altitude, latitude). Results of first attempts of radiation doses modelling confirmed

    The failure of newly qualified Registered Nurses to be appropriately transitioned into the new practice has been mentioned in numerous nursing literatures. Along with the need to decrease turnover rates, increase satisfaction rate of nurses and improve patient outcomes, nursing educators in Singapore are interested in the experiences of these nurses in their transition to practice journey. In this paper, the author attempts to critically review qualitative research conducted in that area to identify why nurses are leaving the profession and how nursing educators in Singapore can reduce stress and uncertainty in the newly qualified Registered Nurses during their transition to practice journey. In conducting a qualitative literature review, the author aims to explore interpretation of these nurses' subjective experiences and description of their social context, ultimately paying attention to lay knowledge as human behaviour is context specific rather than being represented in the quantitative form.

  11. Exploring Shamanic Journeying: Repetitive Drumming with Shamanic Instructions Induces Specific Subjective Experiences but No Larger Cortisol Decrease than Instrumental Meditation Music

    2014-01-01

    Exposure to repetitive drumming combined with instructions for shamanic journeying has been associated with physiological and therapeutic effects, such as an increase in salivary immunoglobulin A. In order to assess whether the combination of repetitive drumming and shamanic instructions is specifically associated with these effects, we compared the effect of listening to either repetitive drumming or instrumental meditation music for 15 minutes on salivary cortisol concentration and on self-reported physiological and psychological states. For each musical style, two groups of participants were exposed to two conditions: instructions for shamanic journeying or relaxation instructions. A total of 39 participants (24 females) inexperienced in shamanic journeying completed the experiment. Salivary cortisol concentrations were measured before and after exposure to music. In addition, participants filled out a mood questionnaire before and after the experiment and completed a post experiment questionnaire on their experiences. A significant decrease in the concentration in salivary cortisol was observed across all musical styles and instructions, indicating that exposure to 15 minutes of either repetitive drumming or instrumental meditation music, while lying down, was sufficient to induce a decrease in cortisol levels. However, no differences were observed across conditions. Significant differences in reported emotional states and subjective experiences were observed between the groups. Notably, participants exposed to repetitive drumming combined with shamanic instructions reported experiencing heaviness, decreased heart rate, and dreamlike experiences significantly more often than participants exposed to repetitive drumming combined with relaxation instructions. Our findings suggest that the subjective effects specifically attributed to repetitive drumming and shamanic journeying may not be reflected in differential endocrine responses. PMID:24999623

    Josef Armin Knapp (1843-1899) as Austrian botanist was interested in development of botanical knowledge of Austro-Hungarian Monarchy--his maternal country. Monarchy, during the long regency of emperor Franz Josef I, was multinational, very much diversified geographically territory. This large empire had included, among others, such countries as present Austria, Hungary, Slovakia, Croatia, Ukraine, Romania and the southern part of present Poland--previously known as Galicia. J. A. Knapp was interested in studying these parts of empire which were considered peripheries and less-known. It seems to have met the requirements of science, economy and administration of Vienna. J. A. Knapp in his large floristic researches had included explorations of considerable part of the Monarchy and had left an interesting scientific legacy. His research papers were results of botanical explorations in selected areas of the Monarchy--area of Nitra (currently a city in Slovakia), Slavonia (presently a land in Croatia) and Galicia (the historical area in the south of Poland). This article refers to the botanical journey of J. A. Knapp in Galicia in summer 1868. The main purpose of his journey was to visit and explore selected places in Galicia--the surroundings of Jaslo and Sanok towns and some specific areas within the Bieszczady Mountains, which are part of the Carpathians Mountains. Botanical researches in the Bieszczady Mountains provided by J. A. Knapp can be considered nowadays as very important and pioneering in that area. In the second part of XIX century this area was highly populated and the observed anthropogenic pressure applied to the nature was strong. Now, the area is considered a very valuable natural territory--since 1973 it has been occupied by the Bieszczady National Park--one of Polish national parks. J. A. Knapp had spent more than two months in Galicia thanks to the great hospitality of Polish people, especially botanists: A. Rehmann, I. R. Czerwiakowski, W. Jab

    This study aimed to develop a grounded theory to describe and explain the experience of pain and its impact, as reported by the individuals who had pain associated with chronic leg ulceration. The Strauss and Corbin grounded theory approach was used. In-depth interviews were undertaken with 11 people aged ≥ 65 years from Leeds in the north of England. All participants were cared for by home care nurses and had painful leg ulceration. The emergent grounded theory centered on a core category of "The journey to chronic pain." The theory suggested a trajectory consisting of three phases that the patient experiences, where the end result is a chronic pain syndrome. In phase 1, leg ulcer pain has predominantly acute nociceptive properties, and if this is not managed effectively, or ulcers do not heal, persistent pain may develop with both nociceptive and neuropathic properties (i.e., phase 2). If phase 2 pain is not managed effectively, patients may then develop refractory long-term pain (phase 3). Those who progress to phase 3 tend to experience negative consequences such as insomnia, depression, and suicidal ideation. Only when health care professionals understand and acknowledge the persistent and long-term nature of the pain in this patient group can the pain be managed effectively.

    Understanding the past is to understand the present. Mammalian life, with all its complexity comes from a humble beginning of a single fertilized egg cell. Achieving this requires an enormous diversification of cellular function, the majority of which is generated through a series of cellular decisions during embryogenesis. The first decisions are made as the embryo prepares for implantation, a process that will require specialization of extra-embryonic lineages while preserving an embryonic one. In this mini-review, we will focus on the mouse as a mammalian model and discuss recent advances in the decision making process of the early embryo. PMID:26343010

  1. Second space Christmas for ESA: Huygens to begin its final journey to Titan/ Media activities.

    NASA Astrophysics Data System (ADS)

    2004-12-01

    At 1.25 billion km from Earth, after a 7-year journey through the Solar system, ESA’s Huygens probe is about to separate from the Cassini orbiter to enter a ballistic trajectory toward Titan, the largest and most mysterious moon of Saturn, in order to dive into its atmosphere on 14 January. This will be the first man-made object to explore in-situ this unique environment, whose chemistry is assumed to be very similar to that of the early Earth just before life began, 3.8 billion years ago. The Cassini-Huygens pair, a joint mission conducted by NASA, ESA and the Italian space agency (ASI), was launched into space on 15 October 1997. With the help of several gravity assist manoeuvres during flybys of Venus, Earth and Jupiter, it took almost 7 years for the spacecraft to reach Saturn. The Cassini orbiter, carrying Huygens on its flank, entered an orbit around Saturn on 1 July 2004, and began to investigate the ringed planet and its moons for a mission that will last at least four years. The first distant flyby of Titan took place on 2-3 July 2004. It provided data on Titan's atmosphere which were confirmed by the data obtained during the first close flyby on 26 October 2004 at an altitude of 1174 km. These data were used to validate the entry conditions of the Huygens probe. A second close flyby of Titan by Cassini-Huygens at an altitude of 1200 km is scheduled on 13 December and will provide additional data to further validate the entry conditions of the Huygens probe. On 17 December the orbiter will be placed on a controlled collision course with Titan in order to release Huygens on the proper trajectory, and on 21 December (some dates and times are subject to minor adjustment for operational reasons, except the entry time on 14 January which is know to within an accuracy of under 2 minutes) all systems will be set up for separation and the Huygens timers will be set to wake the probe a few hours before its arrival at Titan. The Huygens probe is due to separate on

  2. Delivering an evidence-based outdoor journey intervention to people with stroke: Barriers and enablers experienced by community rehabilitation teams

    2010-01-01

    Background Transferring knowledge from research into practice can be challenging, partly because the process involves a change in attitudes, roles and behaviour by individuals and teams. Helping teams to identify then target potential barriers may aid the knowledge transfer process. The aim of this study was to identify barriers and enablers, as perceived by allied health professionals, to delivering an evidence-based (Level 1) outdoor journey intervention for people with stroke. Methods A qualitative design and semi-structured interviews were used. Allied health professionals (n = 13) from two community rehabilitation teams were interviewed, before and after receiving feedback from a medical record audit and attending a training workshop. Interviews allowed participants to identify potential and actual barriers, as well as enablers to delivering the intervention. Qualitative data were analysed using theoretical domains described by Michie and colleagues. Results Two barriers to delivery of the intervention were the social influence of people with stroke and their family, and professionals' beliefs about their capabilities. Other barriers included professionals' knowledge and skills, their role identity, availability of resources, whether professionals remembered to provide the intervention, and how they felt about delivering the intervention. Enablers to delivering the intervention included a belief that they could deliver the intervention, a willingness to expand and share professional roles, procedures that reminded them what to do, and feeling good about helping people with stroke to participate. Conclusions This study represents one step in the quality improvement process. The interviews encouraged reflection by staff. We obtained valuable data which have been used to plan behaviour change interventions addressing identified barriers. Our methods may assist other researchers who need to design similar behaviour change interventions. PMID:20082725

    PubMed

    Carpentier, J L

    1993-09-01

    The data that we have reviewed indicate that insulin binds to a specific cell-surface receptor. The complex then becomes involved in a series of steps which lead the insulin-receptor complex to be internalized and rapidly delivered to endosomes. From this sorting station, the hormone is targeted to lysosomes to be degraded while the receptor is recycled back to the cell surface. This sequence of events presents two degrees of ligand specificity: (a) The first step is ligand-dependent and requires insulin-induced receptor phosphorylation of specific tyrosine residues. It consists in the surface redistribution of the receptor from microvilli where it preferentially localizes in its unoccupied form. (b) The second step is more general and consists in the association with clathrin-coated pits which represents the internalization gate common to many receptors. This sequence of events participates in the regulation of the biological action of the hormone and can thus be implicated in the pathophysiology of diabetes mellitus and various extreme insulin resistance syndromes, including type A extreme insulin resistance, leprechaunism, and Rabson-Mendehall syndrome. Alterations of the internalization process can result either from intrinsic abnormalities of the receptor or from more general alteration of the plasma membrane or of the cell metabolism. Type I diabetes is an example of the latter possibility, since general impairment of endocytosis could contribute to extracellular matrix accumulation and to an increase in blood cholesterol. Thus, better characterization of the molecular and cellular biology of the insulin receptor and of its journey inside the cell definitely leads to better understanding of disease states, including diabetes.

    Biofilms contain group(s) of microorganisms that are found to be associated with the biotic and abiotic surfaces. Biofilms contain either homogenous or heterogeneous populations of bacteria which remain in the matrix made up of extracellular polymeric substances secreted by constituent population of the biofilm. Biofilms can be either single or multilayered. Biofilms are an increasing issue of concern that is gaining importance with each passing day. Due to the ubiquitous nature of biofilms, it is difficult to eradicate them. It has been seen that many infectious diseases harbour biofilms of bacterial pathogens as the reservoir of persisting infections which can prove fatal at times. The presence of biofilms can be seen in diseases like endocarditis, cystic fibrosis, periodontitis, rhinosinusitis and osteomyelitis. The presence of biofilms has been mostly seen in medical implants and urinary catheters. Various signalling events including two-component signalling, extra cytoplasmic function and quorum sensing are involved in the formation of biofilms. The presence of an extracellular polymeric matrix in biofilms makes it difficult for the antimicrobials to act on them and make the bacteria tolerant to antibiotics and other drugs. The aim of this review was to discuss about the basic formation of a biofilm, various signalling cascades involved in biofilm formation, possible mechanisms of drug resistance in biofilms and recent therapeutic approaches involved in successful eradication of biofilms.

  6. Bacterial genotoxins: The long journey to the nucleus of mammalian cells.

    PubMed

    Frisan, Teresa

    2016-03-01

    Bacterial protein genotoxins target the DNA of eukaryotic cells, causing DNA single and double strand breaks. The final outcome of the intoxication is induction of DNA damage responses and activation of DNA repair pathways. When the damage is beyond repair, the target cell either undergoes apoptosis or enters a permanent quiescent stage, known as cellular senescence. In certain instances, intoxicated cells can survive and proliferate. This event leads to accumulation of genomic instability and acquisition of malignant traits, underlining the carcinogenic potential of these toxins. The toxicity is dependent on the toxins' internalization and trafficking from the extracellular environment to the nucleus, and requires a complex interaction with several cellular membrane compartments: the plasma membrane, the endosomes, the trans Golgi network and the endoplasmic reticulum, and finally the nucleus. This review will discuss the current knowledge of the bacterial genotoxins internalization pathways and will highlight the issues that still remain unanswered. This article is part of a Special Issue entitled: Pore-Forming Toxins edited by Mauro Dalla Serra and Franco Gambale.

    Flow-induced K secretion (FIKS) in the aldosterone-sensitive distal nephron (ASDN) is mediated by large-conductance, Ca(2+)/stretch-activated BK channels composed of pore-forming α-subunits (BKα) and accessory β-subunits. This channel also plays a critical role in the renal adaptation to dietary K loading. Within the ASDN, the cortical collecting duct (CCD) is a major site for the final renal regulation of K homeostasis. Principal cells in the ASDN possess a single apical cilium whereas the surfaces of adjacent intercalated cells, devoid of cilia, are decorated with abundant microvilli and microplicae. Increases in tubular (urinary) flow rate, induced by volume expansion, diuretics, or a high K diet, subject CCD cells to hydrodynamic forces (fluid shear stress, circumferential stretch, and drag/torque on apical cilia and presumably microvilli/microplicae) that are transduced into increases in principal (PC) and intercalated (IC) cell cytoplasmic Ca(2+) concentration that activate apical voltage-, stretch- and Ca(2+)-activated BK channels, which mediate FIKS. This review summarizes studies by ourselves and others that have led to the evolving picture that the BK channel is localized in a macromolecular complex at the apical membrane, composed of mechanosensitive apical Ca(2+) channels and a variety of kinases/phosphatases as well as other signaling molecules anchored to the cytoskeleton, and that an increase in tubular fluid flow rate leads to IC- and PC-specific responses determined, in large part, by the cell-specific composition of the BK channels.

    Rice, one of the most important cereal crops for mankind, feeds more than half the world population. Rice has been heralded as a model cereal owing to its small genome size, amenability to easy transformation, high synteny to other cereal crops and availability of complete genome sequence. Moreover, sequence wealth in rice is getting more refined and precise due to resequencing efforts. This humungous resource of sequence data has confronted research fraternity with a herculean challenge as well as an excellent opportunity to functionally validate expressed as well as regulatory portions of the genome. This will not only help us in understanding the genetic basis of plant architecture and physiology but would also steer us towards developing improved cultivars. No single technique can achieve such a mammoth task. Functional genomics through its diverse tools viz. loss and gain of function mutants, multifarious omics strategies like transcriptomics, proteomics, metabolomics and phenomics provide us with the necessary handle. A paradigm shift in technological advances in functional genomics strategies has been instrumental in generating considerable amount of information w.r.t functionality of rice genome. We now have several databases and online resources for functionally validated genes but despite that we are far from reaching the desired milestone of functionally characterizing each and every rice gene. There is an urgent need for a common platform, for information already available in rice, and collaborative efforts between researchers in a concerted manner as well as healthy public-private partnership, for genetic improvement of rice crop better able to handle the pressures of climate change and exponentially increasing population.

  16. Food intake and fuel deposition in a migratory bird is affected by multiple as well as single-step changes in the magnetic field.

    2008-03-01

    Recent studies have shown that migratory thrush nightingales (Luscinia luscinia) experimentally treated with multiple changes of the magnetic field simulating a journey to their target stopover area in northern Egypt, increased fuel deposition as expected in preparation to cross the Sahara desert. To investigate the significance of food intake on the body mass changes observed, in the work described here we analysed food intake of the nightingales under study in those earlier experiments. Furthermore, to study whether a single change in the magnetic field directly to northern Egypt is sufficient to provide information for fuelling decisions, we performed a new experiment, exposing thrush nightingales trapped in Sweden, directly to a magnetic field of northern Egypt. Our results show that an experimentally induced magnetic field of northern Egypt, close to the barrier crossing, triggers the same response in fuel deposition as experiments with multiple changes of the magnetic field simulating a migratory journey from Sweden to Egypt, suggesting that migratory birds do not require successive changes in field parameters to incorporate magnetic information into their migratory program. Furthermore, irrespective of experimental set up (single or multiple changes of the magnetic field parameters) increase in food intake seems to be the major reason for the observed increase in fuelling rate compared with control birds, suggesting that geomagnetic information might trigger hormonal changes in migratory birds enabling appropriate fuelling behaviour during migration.

  3. Geisinger's Retail Innovation Journey.

    In 2003, Geisinger Health System formed a new group, Geisinger Ventures (GV), to accelerate the growth of new lines of business that were extensions of the core mission of the organization. Careworks, the convenient care clinic line of business, began in early 2006 as one of the early components of the GV portfolio. Over the past nine years, Geisinger has tested several retail and walk-in models, including in-store clinics, separate retail sites, and models colocated with primary care practices and emergency departments. Each site and model presents different benefits and challenges with respect to patient care, marketing, staffing, and clinical integration. With the implementation of healthcare reform and a decision to participate in Medicaid'managed care, Geisinger's strategic need for convenient care options has intensified, and new models, including e-visits and telemedicine specialty consultations, are being actively explored. Geisinger's view is that healthcare is rapidly changing, being affected by demographic shifts, diagnostic and treatment options, payment changes, and communication technologies. Healthcare delivery must flex to adjust to these and other trends, and retail clinics are part of that response. Careful examination of the critical elements necessary for optimal care (including wellness, prevention, and management of chronic disease and severe multimorbid disease) and then matching those elements to the optimal mode and site of care will lead to a streamlined healthcare system. The historical--and still most prevalent--methodology of traditional office, emergency department, and inpatient care options are not ideal for all patients' care needs in the twenty-first century. A thoughtful, deliberate extension of those options will be necessary. Rather than simply adding a static retail or virtual offering, medical professionals should develop a process to continually assess patients, technology, payment, and disease changes so that they are constantly adding exciting new options to the clinical delivery model. The ability to assess and respond to the changes that these varied inputs drive will be the most important element of success for the future.

    It isn't always easy to change leadership hats or to alter the way you assess a business problem. Under pressure, most executives fall back on the management style or approach that worked in the last crisis they faced. But old approaches rarely work in new and demanding situations. Just ask Leonard Schaeffer, chairman and CEO of WellPoint Health Networks, one of the country's largest and most successful managed-care companies. In this account, he describes how he consciously adopted three very different styles of leadership at critical points during his 30-year career, depending on the business challenges at hand. Schaeffer headed up the U.S. Health Care Finance Administration during the Carter years--and led the charge toward more efficient work practices at that agency. Then he transformed Blue Cross of California from a floundering bureaucracy losing close to $1 million each day into a strong public company, WellPoint. The dire circumstances at Blue Cross had dictated that Schaeffer initially be an autocratic leader, which he considers the managerial equivalent of being an emergency room surgeon--forced to do whatever it takes to save a patient's life. But as the company rebounded, the CEO shed that "any decision is better than no decision" style. He has become a participative, hands-off leader-setting strategies and goals from above but letting WellPoint's line managers and executives figure out how best to achieve those goals. Most recently, Schaeffer has turned into a reformer--a leader who works with one foot outside the company to spur changes in health care and society. There are pitfalls in switching leadership styles, Schaeffer admits, but this flexibility is necessary for realizing corporate- and personal-success. PMID:12389460

    If you could see the road ahead, you might pass up a fantastic opportunity because you're blinded by the potential pitfalls. In my case, I was testing the project management waters at the NASA Dryden Flight Research Center after ten years of being a research engineer. I was an eager (but ignorant) rookie project manager (PM) and I was willing to engage in just about any project without knowing what it would entail. The assignment I accepted was to help NASA's Environment Research Aircraft and Sensor Technology (ERAST) Project, a partnership with a fledgling Uninhabited Aerial Vehicle (UAV) industry, to tackle stratospheric flight. I remember one of our industrial partners querying me about whether or not I understood what 1 was getting into. Like one of those bobble-head toys that have become quite popular, I nodded. But in reality, I didn't have a clue. His response was, "Hang on, it's going to be a wild ride." He was right. In retrospect, if I had clearly understood the ten years of pitfalls that were coming, I might not have "hung on." Now I can look back and say that I would not trade the experience for anything. The lows included the destruction of a number of UAVs on my watch. Later someone told me that we should not be surprised if we lost one UAV for every ten flights. We wrote many chapters in the book on what can go wrong with UAVs-and we are still writing. As you can imagine, each mishap was accompanied by an investigation. What an education!

    Is it possible to make people fall in love with minerals? Yes, it is. And it happens daily at terra mineralia, a permanent exhibition displaying a collection of 3500 rare and beautiful minerals, precious stones and meteorites in Freiberg/Saxony. The exhibits are part of one of the world's largest private collections of minerals and have been given to the TU Bergakademie Freiberg on permanent loan by Dr. Erika Pohl-Ströher. The exquisite pieces stem from sites on every continent, and as such, allow the visitor to virtually journey around the world to the world's most beautiful minerals - an amazing and unexpected experience. The specimen are so unique in quality and aesthetical appearance that scientists and private collectors from all over the world are overwhelmed by their display. However, the exhibition is less targeted towards the specialist or collector. Due to the close ties of the terra mineralia to its parent organization, the TU Bergakademie Freiberg, which is one of the leading universities dedicated to the geo-sciences, it has been primarily designed to attract young visitors, school children and students. It is the expressed goal of the University and Dr. Erika Pohl-Ströher to give young people the opportunity to discover the fascinating aspects natural sciences have to offer. Therefore, the efforts of the museums educational service focus on raising awareness and enticing the young 'scientists' to be. Why not continue a live of learning where the interest in natural sciences had been nurtured in first place - at the TU Bergakademie in Freiberg, for example with studies in the fields of mineralogy, geology or mining? And while you are at it, come back to terra mineralia as a student to help form and train the next generation of young talents. So, does it work? Yes, even if it is still too early to see the young enrolled in the University. What we already see, is a tremendous amount of positive feed back from the young, their parents and educators

    During these last two years less drug regimens (LDRs) in HIV, and in particular protease inhibitor (PI)/r-based strategies, have been explored both in clinical trials and in clinical practice. Many results are now available and more is known about how to use them safely and effectively. Understanding that an LDR strategy represents a real tailored therapeutic approach for the patient is crucial for the long-term success and positive management of HIV infection. Trust between patients and HIV specialists and a real focus on the patient's life are key factors for long life treatment success, in particular when using a LDR strategy. This is clearly shown by the HIV patient's journey (HPJ) methodology, used in an Italian national workshop to better define the criteria and challenges of LDR strategies. This paper shows the results of this complex process.

    Dynamically regulated changes in chromatin states are vital for normal development and can produce disease when they go awry. Accordingly, much effort has been devoted to characterizing these states under normal and pathological conditions. Chromatin immunoprecipitation followed by sequencing (ChIP-seq) is the most widely used method to characterize where in the genome transcription factors, modified histones, modified nucleotides and chromatin binding proteins are found; bisulfite sequencing (BS-seq) and its variants are commonly used to characterize the locations of DNA modifications. Though very powerful, these methods are not without limitations. Notably, they are best at characterizing one chromatin feature at a time, yet chromatin features arise and function in combination. Investigators commonly superimpose separate ChIP-seq or BS-seq datasets, and then infer where chromatin features are found together. While these inferences might be correct, they can be misleading when the chromatin source has distinct cell types, or when a given cell type exhibits any cell to cell variation in chromatin state. These ambiguities can be eliminated by robust methods that directly characterize the existence and genomic locations of combinations of chromatin features in very small inputs of cells or ideally, single cells. Here we review single molecule epigenomic methods under development to overcome these limitations, the technical challenges associated with single molecule methods and their potential application to single cells.

The single photon pulses are emitted on demand by a single nitrogen-vacancy color center in a diamond nanocrystal. The quantum bit error rate is less that 4.6% and the secure bit rate is 7700 bits/s. The overall performances of our system reaches a domain where single photons have a measurable advantage over an equivalent system based on attenuated light pulses.

    Single neutral atoms are promising candidates for qubits, the fundamental unit of quantum information. We have built a set of optical tweezers for trapping and moving single Rubidium atoms. The tweezers are based on a far off-resonant dipole trapping laser focussed to a 1 μm spot with a single aspheric lens. We use a digital micromirror device (DMD) to generate dynamic holograms of the desired arrangement of traps. The DMD has a frame rate of 20 kHz which, when combined with fast algorithms, allows for rapid reconfiguration of the traps. We demonstrate trapping of up to 20 atoms in arbitrary arrangements, and the transport of a single-atom over a distance of 14 μm with continuous laser cooling, and 5 μm without. In the meantime, we are developing high-finesse fibre-tip cavities, which we plan to use to couple pairs of single atoms to form a quantum network.

    The adoption of plasmonic nanomaterials in optical sensors, coupled with the advances in detection techniques, has opened the way for biosensing with single plasmonic particles. Single nanoparticle sensors offer the potential to analyse biochemical interactions at a single-molecule level, thereby allowing us to capture even more information than ensemble measurements. We introduce the concepts behind single nanoparticle sensing and how the localised surface plasmon resonances of these nanoparticles are dependent upon their materials, shape and size. Then we outline the different synthetic approaches, like citrate reduction, seed-mediated and seedless growth, that enable the synthesis of gold and silver nanospheres, nanorods, nanostars, nanoprisms and other nanostructures with tunable sizes. Further, we go into the aspects related to purification and functionalisation of nanoparticles, prior to the fabrication of sensing surfaces. Finally, the recent developments in single nanoparticle detection, spectroscopy and sensing applications are discussed. PMID:26473866

    Whole genome amplification and next-generation sequencing of single cells has become a powerful approach for studying uncultivated microorganisms that represent 90–99 % of all environmental microbes. Single cell sequencing enables not only the identification of microbes but also linking of functions to species, a feat not achievable by metagenomic techniques. Moreover, it allows the analysis of low abundance species that may be missed in community-based analyses. It has also proved very useful in complementing metagenomics in the assembly and binning of single genomes. With the advent of drastically cheaper and higher throughput sequencing technologies, it is expected that single cell sequencing will become a standard tool in studying the genome and transcriptome of microbial communities.

    NASA Astrophysics Data System (ADS)

    Lounis, Brahim; Orrit, Michel

    2005-05-01

    The concept of the photon, central to Einstein's explanation of the photoelectric effect, is exactly 100 years old. Yet, while photons have been detected individually for more than 50 years, devices producing individual photons on demand have only appeared in the last few years. New concepts for single-photon sources, or 'photon guns', have originated from recent progress in the optical detection, characterization and manipulation of single quantum objects. Single emitters usually deliver photons one at a time. This so-called antibunching of emitted photons can arise from various mechanisms, but ensures that the probability of obtaining two or more photons at the same time remains negligible. We briefly recall basic concepts in quantum optics and discuss potential applications of single-photon states to optical processing of quantum information: cryptography, computing and communication. A photon gun's properties are significantly improved by coupling it to a resonant cavity mode, either in the Purcell or strong-coupling regimes. We briefly recall early production of single photons with atomic beams, and the operation principles of macroscopic parametric sources, which are used in an overwhelming majority of quantum-optical experiments. We then review the photophysical and spectroscopic properties and compare the advantages and weaknesses of various single nanometre-scale objects used as single-photon sources: atoms or ions in the gas phase and, in condensed matter, organic molecules, defect centres, semiconductor nanocrystals and heterostructures. As new generations of sources are developed, coupling to cavities and nano-fabrication techniques lead to improved characteristics, delivery rates and spectral ranges. Judging from the brisk pace of recent progress, we expect single photons to soon proceed from demonstrations to applications and to bring with them the first practical uses of quantum information.

  20. Single spin magnetic resonance

    2016-08-01

    Different approaches have improved the sensitivity of either electron or nuclear magnetic resonance to the single spin level. For optical detection it has essentially become routine to observe a single electron spin or nuclear spin. Typically, the systems in use are carefully designed to allow for single spin detection and manipulation, and of those systems, diamond spin defects rank very high, being so robust that they can be addressed, read out and coherently controlled even under ambient conditions and in a versatile set of nanostructures. This renders them as a new type of sensor, which has been shown to detect single electron and nuclear spins among other quantities like force, pressure and temperature. Adapting pulse sequences from classic NMR and EPR, and combined with high resolution optical microscopy, proximity to the target sample and nanoscale size, the diamond sensors have the potential to constitute a new class of magnetic resonance detectors with single spin sensitivity. As diamond sensors can be operated under ambient conditions, they offer potential application across a multitude of disciplines. Here we review the different existing techniques for magnetic resonance, with a focus on diamond defect spin sensors, showing their potential as versatile sensors for ultra-sensitive magnetic resonance with nanoscale spatial resolution.

    Surface plasmon polaritons are electromagnetic waves coupled to collective electron oscillations propagating along metal-dielectric interfaces, exhibiting a bosonic character. Recent experiments involving surface plasmons guided by wires or stripes allowed the reproduction of quantum optics effects, such as antibunching with a single surface plasmon state, coalescence with a two-plasmon state, conservation of squeezing, or entanglement through plasmonic channels. We report the first direct demonstration of the wave-particle duality for a single surface plasmon freely propagating along a planar metal-air interface. We develop a platform that enables two complementary experiments, one revealing the particle behavior of the single-plasmon state through antibunching, and the other one where the interferences prove its wave nature. This result opens up new ways to exploit quantum conversion effects between different bosonic species as shown here with photons and polaritons. PMID:26998521

    We show that aberration-corrected scanning transmission electron microscopy operating at low accelerating voltages is able to analyze, simultaneously and with single atom resolution and sensitivity, the local atomic configuration, chemical identities, and optical response at point defect sites in monolayer graphene. Sequential fast-scan annular dark-field (ADF) imaging provides direct visualization of point defect diffusion within the graphene lattice, with all atoms clearly resolved and identified via quantitative image analysis. Summing multiple ADF frames of stationary defects produce images with minimized statistical noise and reduced distortions of atomic positions. Electron energy-loss spectrum imaging of single atoms allows the delocalization of inelastic scattering to be quantified, and full quantum mechanical calculations are able to describe the delocalization effect with good accuracy. These capabilities open new opportunities to probe the defect structure, defect dynamics, and local optical properties in 2D materials with single atom sensitivity.

    Single Bubble Sonoluminescence is the emission of light from a single bubble suspended in a liquid caused by a continuum of repeated implosions due to pressure waves generated from a maintained ultrasonic sinusoidal wave source. H. Frenzel and H. Schultz first studied it in 1934 at the University of Cologne. It was not until 1988 with D.F. Gaitan that actual research began with single bubble sonoluminescence. Currently many theories exist attempting to explain the observed bubble phenomenon. Many of these theories require spherical behavior of the bubble. Observation of the bubble has shown that the bubble does not behave spherically in most cases. One explanation for this is known as jet theory. A spectrum of the bubble will give us the mean physical properties of the bubble such as temperature and pressure inside the bubble. Eventually, with the aide of fluorocene dye a full spectrum of the bubble will be obtained.

    A means and method for single event time of flight mass spectrometry for analysis of specimen materials. The method of the invention includes pulsing an ion source imposing at least one pulsed ion onto the specimen to produce a corresponding emission of at least one electrically charged particle. The emitted particle is then dissociated into a charged ion component and an uncharged neutral component. The ion and neutral components are then detected. The time of flight of the components are recorded and can be used to analyze the predecessor of the components, and therefore the specimen material. When more than one ion particle is emitted from the specimen per single ion impact, the single event time of flight mass spectrometer described here furnis This invention was made with Government support under Contract No. W-7405-ENG82 awarded by the Department of Energy. The Government has certain rights in the invention.

  9. Single Cell Oncogenesis

    NASA Astrophysics Data System (ADS)

    Lu, Xin

    It is believed that cancer originates from a single cell that has gone through generations of evolution of genetic and epigenetic changes that associate with the hallmarks of cancer. In some cancers such as various types of leukemia, cancer is clonal. Yet in other cancers like glioblastoma (GBM), there is tremendous tumor heterogeneity that is likely to be caused by simultaneous evolution of multiple subclones within the same tissue. It is obvious that understanding how a single cell develops into a clonal tumor upon genetic alterations, at molecular and cellular levels, holds the key to the real appreciation of tumor etiology and ultimate solution for therapeutics. Surprisingly very little is known about the process of spontaneous tumorigenesis from single cells in human or vertebrate animal models. The main reason is the lack of technology to track the natural process of single cell changes from a homeostatic state to a progressively cancerous state. Recently, we developed a patented compound, photoactivatable (''caged'') tamoxifen analogue 4-OHC and associated technique called optochemogenetic switch (OCG switch), which we believe opens the opportunity to address this urgent biological as well as clinical question about cancer. We propose to combine OCG switch with genetically engineered mouse models of head and neck squamous cell carcinoma and high grade astrocytoma (including GBM) to study how single cells, when transformed through acute loss of tumor suppressor genes PTEN and TP53 and gain of oncogenic KRAS, can develop into tumor colonies with cellular and molecular heterogeneity in these tissues.

  10. SINGLE CRYSTAL NEUTRON DIFFRACTION.

    KOETZLE,T.F.

    2001-03-13

    Single-crystal neutron diffraction measures the elastic Bragg reflection intensities from crystals of a material, the structure of which is the subject of investigation. A single crystal is placed in a beam of neutrons produced at a nuclear reactor or at a proton accelerator-based spallation source. Single-crystal diffraction measurements are commonly made at thermal neutron beam energies, which correspond to neutron wavelengths in the neighborhood of 1 Angstrom. For high-resolution studies requiring shorter wavelengths (ca. 0.3-0.8 Angstroms), a pulsed spallation source or a high-temperature moderator (a ''hot source'') at a reactor may be used. When complex structures with large unit-cell repeats are under investigation, as is the case in structural biology, a cryogenic-temperature moderator (a ''cold source'') may be employed to obtain longer neutron wavelengths (ca. 4-10 Angstroms). A single-crystal neutron diffraction analysis will determine the crystal structure of the material, typically including its unit cell and space group, the positions of the atomic nuclei and their mean-square displacements, and relevant site occupancies. Because the neutron possesses a magnetic moment, the magnetic structure of the material can be determined as well, from the magnetic contribution to the Bragg intensities. This latter aspect falls beyond the scope of the present unit; for information on magnetic scattering of neutrons see Unit 14.3. Instruments for single-crystal diffraction (single-crystal diffractometers or SCDs) are generally available at the major neutron scattering center facilities. Beam time on many of these instruments is available through a proposal mechanism. A listing of neutron SCD instruments and their corresponding facility contacts is included in an appendix accompanying this unit.

    Long-distance migrants have developed diverse strategies to deal with the challenges imposed by their annual journeys. These are relatively well studied in some avian groups, such as passerines, shorebirds and raptors. In contrast, few studies have addressed the migratory behaviour of pelagic birds in the light of current theories of optimal migration. Using a dataset of 100 complete migratory tracks gathered along four years, we performed a detailed study on the migratory strategy of a pelagic trans-equatorial migrant, the Cory's shearwater Calonectris diomedea. We analysed daily routines, stopover ecology and travel speed, as well as the influence of the moon on several behavioural patterns. Cory's shearwaters adopted a "fly-and-forage" strategy when migrating, similarly to what has been observed in some raptors. However, by flying by dynamic soaring, shearwaters attained high overall migration speeds, and were able to travel thousands of kilometres without making major stopovers and, apparently, without a noticeable pre-migratory fattening period. Other major findings of this study include the ability to adapt daily schedules when crossing major ecological barriers, and the constant adjustment of migration speed implying higher rates of travel in the pre-breeding movement, with a final sprint to the nesting colony. The present study also highlights a preference of Cory's shearwaters for starting travel at twilight and documents a strong relationship between their migratory activity and the moon phase.

    The distinction between linguistic and non-linguistic knowledge is particularly relevant because it is related to the principle of compositionality during sentence comprehension. Hagoort, Hald, Bastiaansen, and Petersson (2004) challenged the distinction between linguistic and non-linguistic knowledge. Here, we investigate how linguistic and non-linguistic violations are processed in a setting adapted from Hagoort et al., whilst in contrast to Hagoort, keeping the critical word identical. In line with the findings by Hagoort et al., our results showed largest N400 amplitudes for semantic violations ('Journeys are stripy'), followed by non-linguistic world-knowledge violations ('Ladybirds are stripy') and contingent sentences ('Trousers are stripy'), and finally by correct sentences ('Zebras are stripy'). Traditional fractional area and relative criterion measures of peak and onset latencies showed no effect of violation type. Interestingly, the semantic violation condition crossed a fixed criterion earlier than the word-knowledge violation condition. In conclusion, our data suggests that the question regarding the distinction between linguistic- and non-linguistic knowledge in terms of language integration remains open. Implications for future studies addressing the difference between linguistic and non-linguistic knowledge are discussed.

  13. Mawson and Mertz: a re-evaluation of their ill-fated mapping journey during the 1911-1914 Australasian Antarctic Expedition.

    PubMed

    Carrington-Smith, Denise

    During the Australasian Antarctic Expedition of 1911-1914, Douglas Mawson and two companions, Belgrave Ninnis and Xavier Mertz, undertook an ill-fated mapping journey. Ninnis died when he fell down a crevasse, together with the sledge carrying most of their food supplies, and later Mertz became ill and died. Only Mawson returned. In 1969, Cleland and Southcott proposed that Mertz died of vitamin A toxicity and Mawson suffered from the effects of hypervitaminosis A because, with little food left, they were forced to eat their surviving dogs, including the liver. This hypothesis was supported by Shearman in 1978. After re-evaluating this hypothesis, I propose that Mawson and Mertz suffered from the effects of severe food deprivation, not from hypervitaminosis A, and that Mertz died as he was unable to tolerate the change from his usual vegetarian diet to a diet of mainly dog meat. I also suggest that Mertz's condition was aggravated by the psychological stress of being forced to eat the dogs he had cared for for 18 months.

    Among numerous cytokines modulating natural killer (NK) cell function, interleukin 15 (IL-15) exerts a broad range of effect from development and homeostasis, to activation of mature NK cells during infection. Its significance is further highlighted by clinical trials in which IL-15 is being used to boost the proliferation and anti-tumor response of NK cells. Among the signal transduction pathways triggered by the engagement of IL-15 receptor with its ligand, the PI3K–AKT–mTOR pathway seems to be critical for the IL-15-mediated activation of NK cells, therefore being responsible for efficient anti-viral and anti-tumor responses. This review provides an overview of the role of IL-15 at multiple stages of NK cell life journey. Understanding the pathway by which IL-15 conveys critical signals for the generation of NK cells with efficient effector functions, in combination with established protocols for NK cell expansion ex vivo, will undoubtedly open new avenues for therapeutic applications for immunomodulation against infections and cancers.

    Direct spectroscopic evidence for a hydride bridge in the Ni–R form of [NiFe] hydrogenase has been obtained using iron-specific nuclear resonance vibrational spectroscopy (NRVS). The Ni–H–Fe wag mode at 675 cm−1 is the first spectroscopic evidence for a bridging hydride in Ni–R as well as the first iron-hydride-related NRVS feature observed for a biological system. Although density function theory (DFT) calculation assisted the determination of the Ni–R structure, it did not predict the Ni–H–Fe wag mode at ∼675 cm−1 before NRVS. Instead, the observed Ni–H–Fe mode provided a critical reference for the DFT calculations. While the overall science about Ni–R is presented and discussed elsewhere, this article focuses on the long and strenuous experimental journey to search for and experimentally identify the Ni–H–Fe wag mode in a Ni–R sample. As a methodology, the results presented here will go beyond Ni–R and hydrogenase research and will also be of interest to other scientists who use synchrotron radiation for measuring dilute samples or weak spectroscopic features.

    The purpose of this study is to explore the cultural practices and communication tensions perceived among Māori kaumātua (elders) and their whānaunga (extended family) during the end-of-life journey. Further, the study aims to explore the manner in which the tensions are managed. The study was framed by relational dialectics theory and included interviews with 21 kaumātua and focus groups with 39 whānau members. The study identified three cultural practices (dying at home, prayer, and song) that helped to build connection among the family members and also helped to connect the dying person to the spiritual world. Further, four communication tensions were noted: (a) autonomy and connection; (b) conflict and connection; (c) isolation and connection; and (d) balancing the needs of self and other. To manage these tensions, the following strategies were used: (a) coordination conversations; (b) inclusion in decision-making conversations; (c) emotional support within the whānau; and (d) passing on lessons to the next generation.

    Single-molecule manipulation studies open a door for a close-up investigation of complex biological interactions at the molecular level. In these studies, single biomolecules are pulled while their force response is being monitored. The process is often nonequilibrium, and interpretation of the results has been challenging. We used the atomic force microscope to pull proteins and DNA, and determined the equilibrium properties of the molecules using the recently derived nonequilibrium work theorem. I will present applications of the technique in areas ranging from fundamental biological problems such as DNA mechanics, to complex medical processes such as the mechanical activation of von Willebrand Factor, a key protein in blood coagulation.

    2004-03-31

    As an innovative way of enzyme stabilization, we recently developed a new enzyme composite of nano-meter scale that we call "single-enzyme nanoparticles (SENs)" (9). Each enzyme molecule is surrounded with a porous composite organic/inorganic network of less than a few nanometers think. This approach represents a new type of enzyme-containing nanostructure. In experiments with perotease (chymotrypsin, CT), the activity of single enzyme nanoparticle form of the enzyme was greatly stabilized compared to the free form, without imposing a serious mass transfer limitation of substrates. In this chapter we will describe the synthesis, characterization and catalytic activity of the new SENs.
