The educational journeys of first-generation college women in STEM: A grounded theory study

Science.gov (United States)

Geier, Susan

The purpose of this study was to ascertain the various factors that influenced these first-generation college women as they chose a college and selected a STEM major and subsequently persisted to upper level (junior/senior) status. Twenty-five first-generation college women in STEM majors who attended a research-intensive university in the Midwest were interviewed. Approaching this study using constructivist grounded theory provided the opportunity for deeper insights by examining data at a conceptual level while preserving the voices of the women in this study. The women faced numerous challenges on their journeys, yet they persisted. As the women in this study selected and persisted in STEM, they demonstrated thoughtful determination, experienced shifting identities, established purposeful relationships and applied forward thinking, as they practiced high-stakes decision-making during their journeys. The experiences of these women, namely first-generation women in STEM fields, may inform students, parents, educators, researchers, and policymakers concerned with (a) inspiring students to consider STEM majors, (b) fostering student success in STEM throughout their academic journeys, and (c) ultimately increasing the number of underrepresented minorities and women in the STEM fields.

Hawaii's annual Journey through the Universe program is a flagship Gemini public education and outreach event that engages the public, teachers, astronomers, engineers, thousands of local students and staff from all of the Mauna Kea Observatories. The program inspires, educates, and engages teachers, students, and their families as well as the community. From February 10-18, 2011, fifty-one astronomy educators from observatories on Mauna Kea and across the world visited over 6,500 students in 310 classrooms at 18 schools. Two family science events were held for over 2,500 people at the 'Imiloa Astronomy Education Center and the University of Hawaii at Hilo. The local Chamber of Commerce(s) held an appreciation celebration for the astronomers attended by over 170 members from the local government and business community. Now going into its eighth year in Hawaii, the 2012 Journey Through the Universe program will continue working with the observatories on Mauna Kea and with the NASA Lunar Science Institute (NLSI). As a new partner in our Journey program, NLSI will join the Journey team (Janice Harvey, Gemini Observatory, Journey Team Leader) and give an overview of the successes and future developments of this remarkable program and its growth. The future of America rests on our ability to train the next generation of scientists and engineers. Science education is key and Journey through the Universe opens the doors of scientific discovery for our students. www.gemini.edu/journey

Goethe's Italian Journey and the geological landscape

Science.gov (United States)

Coratza, Paola; Panizza, Mario

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 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.

Refocusing Seafood Sustainability as a Journey Using the Law of the Minimum

Directory of Open Access Journals (Sweden)

Elizabeth Fitzsimons

2012-08-01

Full Text Available Globally, seafood is an important protein source because it is a nutritious food source produced with relative efficiency compared to other proteins. Because of problems related to overfishing and deleterious environmental impacts, over the last decade, non-governmental organizations (NGOs have increased their focus on seafood sustainability while businesses have incorporated this issue into their corporate social responsibility (CSR reporting. Sustainability is a concept that can be addressed in terms of scale of issues considered (narrow vs. broad as well as the scope of how they are measured (undemanding or demanding. Currently, the message of seafood sustainability is becoming complicated in that the journey toward sustainability is being referred to as having achieved a state of sustainability. In addition, companies making a “sustainable” declaration are often at different points in the “scale/scope” arena. As a result, buyers, retailers and consumers have difficulty differentiating between these products. Furthermore, they often assume that a “sustainable” product has no further need for improvement, when in fact this is rarely the case. This change in reference from a continual process (a journey to a static point (it is sustainable limits further advances in seafood sustainability and the drive for continual improvement. Herein, the “Law of the Minimum”, growth toward an end goal will occur until one factor becomes limiting, is adopted as an analogy for sustainability. By refocusing the sustainability discussion on a progressive series of challenges to be met, the discussion will return to the journey as the central point. Doing so will help refresh the dialogue around seafood, and to create new opportunities for improvement.

The mental health consequences of student "Holocaust memorial journeys".

Mimouni-Bloch, Aviva; Walter, Garry; Ross, Sharon; Bloch, Yuval

2013-08-01

Our aim was to study the mental health consequences of Israeli adolescents' 8-day "Holocaust memorial journey" to Poland. A survey to ascertain the experience of Israeli child and adolescent psychiatrists and residents in the specialty was conducted. Participants were asked about referrals regarding the memorial journey, and to compare these cases with referrals for other potentially traumatic events, including school "sleep-out" trips. Fifty child and adolescent psychiatrists and residents participated. According to their collective experience, the adolescents' memorial journey triggered a variety of mental health problems, including psychosis, but only one case of post-traumatic stress disorder (PTSD). Judging by the number of referrals, there was a higher rate of mental health problems following the memorial journey than after the annual sleep-out school trip. Although it may seldom lead to PTSD, the Holocaust memorial journey can be a major stressor for some participating teenagers. Evaluating "high risk" adolescents prior to their planned exposure to likely stressors and conducting large, prospective studies that examine the impact of pre-planned stressors on the lives of adolescents are warranted. Providing support to all adolescents before, during and after exposure to anticipated stressors is important.

To measure levels of fine particulate matter in the rear passenger area of cars where smoking does and does not take place during typical real-life car journeys. Fine particulate matter (PM(2.5)) was used as a marker of secondhand smoke and was measured and logged every minute of each car journey undertaken by smoking and non-smoking study participants. The monitoring instrument was located at breathing zone height in the rear seating area of each car. Participants were asked to carry out their normal driving and smoking behaviours over a 3-day period. 17 subjects (14 smokers) completed a total of 104 journeys (63 smoking journeys). Journeys averaged 27 min (range 5-70 min). PM(2.5) levels averaged 85 and 7.4 μg/m(3) during smoking and non-smoking car journeys, respectively. During smoking journeys, peak PM(2.5) concentrations averaged 385 μg/m(3), with one journey measuring over 880 μg/m(3). PM(2.5) concentrations were strongly linked to rate of smoking (cigarettes per minute). Use of forced ventilation and opening of car windows were very common during smoking journeys, but PM(2.5) concentrations were still found to exceed WHO indoor air quality guidance (25 μg/m(3)) at some point in the measurement period during all smoking journeys. PM(2.5) concentrations in cars where smoking takes place are high and greatly exceed international indoor air quality guidance values. Children exposed to these levels of fine particulate are likely to suffer ill-health effects. There are increasing numbers of countries legislating against smoking in cars and such measures may be appropriate to prevent the exposure of children to these high levels of secondhand smoke.

The aim of this study was to understand how nurses in a 25-bed critical-access hospital (CAH) led change to become the 1st to achieve Magnet®. Approximately 21% of the US population lives in rural areas served by CAHs. Rural nurse executives are particularly challenged with limited resources. Staff nurses, nurse managers, interprofessional care providers, the chief nursing officer, and board of directors (n = 27) were interviewed. Observations of hospital units and administrative meetings were done, and hospital reports were analyzed. Nine themes emerged to support a conceptual model of leading change. The CAH spent 3 years of its 6-year journey establishing organizational readiness. Nurses overcame complex challenges by balancing operational support and fostering relationships. The Magnet journey led to significantly improved nurse and patient outcomes. A new organizational culture centered on shared governance, evidence-based practice, and higher education emerged. The journey to Magnet leads to improved nurse, patient, and organization outcomes.

Bereaved parents experience significant psychosocial and health sequelae, suggesting that this population may benefit from the ongoing extension of support and resources throughout the grief journey. The interaction of hospital staff with patients and families at the end of a child's life and after death profoundly affects parental grief, offering a unique opportunity for the medical community to positively impact the bereavement experience. The current study was conducted to explore the role of the health care team and medical institutions in the grief journeys of parents whose child died a cancer-related death. Eleven bereaved parents participated in 2 focus groups. Responses to each of the 3 main prompts were coded and analyzed independently using semantic content analysis techniques. Four main concepts were identified within the parental narratives, including the importance of strong and ongoing relationships between providers and bereaved families, the importance of high-quality communication, the effect of negative experiences between providers and families on parental grief, and the importance of the institution's role in the grief journeys of bereaved parents. Bereaved parents consistently identified the critical role played by medical staff and medical institutions throughout the grief journey. Key components of bereavement support identified by parents should serve to guide the actions of providers as well as provide a template for the development of a comprehensive bereavement program within an institution.

Virtual Reality for Prototyping Service Journeys

Directory of Open Access Journals (Sweden)

Costas Boletsis

2018-04-01

Full Text Available The use of virtual elements for developing new service prototyping environments and more realistic simulations has been suggested as a way to optimise the service prototyping process. This work examines the application of virtual reality (VR in prototyping service journeys and it hypothesises that VR can recreate service journeys in a highly immersive, agile, and inexpensive manner, thus allowing users to have a representative service experience and enabling service designers to extract high-quality user feedback. To that end, a new service prototyping method, called VR service walkthrough, is presented and evaluated through an empirical comparative study. A VR service walkthrough is a virtual simulation of a service journey, representing how the service unfolds over space and time. A comparative study between the VR service walkthrough method and an adapted service walkthrough method evaluates the application of both methods using a location-based audio tour guide service as a case study. Two user groups (each with 21 users were used to evaluate both methods based on two factors: the user experience they offered and the subjective meaningfulness and quality of feedback they produced. Results show that the VR service walkthrough method gave a performance similar to that of the service walkthrough method. It was also able to communicate the service concept in an immersive way and foster constructive feedback.

Multi-dimensional knowledge translation: enabling health informatics capacity audits using patient journey models.

Catley, Christina; McGregor, Carolyn; Percival, Jennifer; Curry, Joanne; James, Andrew

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.

Full Text Available Road stories are significant cultural objects that “provide a ready space for [the] exploration” (Cohan and Hark 1997, 2 of different landscapes, contributing to the encounter of the traveller with him/herself or with the Other. These cultural encounters offer the opportunity both for inner reflection upon the nation in which the protagonists travel. Such is the case of the Whitman brothers in The Darjeeling Limited (2007, Wes Anderson, who embark on a journey in India, seeking spiritual enlightenment from the problems of the past. The confrontation with the foreign Other will not only put into perspective a changed notion of the Indian nation but also their true purpose in life. Based upon the idea of the transformative power of journeys, and considering The Darjeeling Limited as a road movie, this article analyzes the brothers’ awakening as they travel deeper into the Indian landscape to emerge with a renewed sense of self.

Journeys through antigravity?

Science.gov (United States)

Carrasco, John Joseph M.; Chemissany, Wissam; Kallosh, Renata

2014-01-01

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.

Community and inquiry: journey of a science teacher

Science.gov (United States)

Goldberg, Jennifer; Welsh, Kate Muir

2009-09-01

In this case study, we examine a teacher's journey, including reflections on teaching science, everyday classroom interaction, and their intertwined relationship. The teacher's reflections include an awareness of being "a White middle-class born and raised teacher teaching other peoples' children." This awareness was enacted in the science classroom and emerges through approaches to inquiry . Our interest in Ms. Cook's journey grew out of discussions, including both informal and semi-structured interviews, in two research projects over a three-year period. Our interest was further piqued as we analyzed videotaped classroom interaction during science lessons and discovered connections between Ms. Cook's reflections and classroom interaction. In this article, we illustrate ways that her journey emerges as a conscientization. This, at least in part, shapes classroom interaction, which then again shapes her conscientization in a recursive, dynamic relationship. We examine her reflections on her "hegemonic (cultural and socio-economic) practices" and consider how these reflections help her reconsider such practices through analysis of classroom interaction. Analyses lead us to considering the importance of inquiry within this classroom community.

Remembering to learn: independent place and journey coding mechanisms contribute to memory transfer.

Science.gov (United States)

Bahar, Amir S; Shapiro, Matthew L

2012-02-08

The neural mechanisms that integrate new episodes with established memories are unknown. When rats explore an environment, CA1 cells fire in place fields that indicate locations. In goal-directed spatial memory tasks, some place fields differentiate behavioral histories ("journey-dependent" place fields) while others do not ("journey-independent" place fields). To investigate how these signals inform learning and memory for new and familiar episodes, we recorded CA1 and CA3 activity in rats trained to perform a "standard" spatial memory task in a plus maze and in two new task variants. A "switch" task exchanged the start and goal locations in the same environment; an "altered environment" task contained unfamiliar local and distal cues. In the switch task, performance was mildly impaired, new firing maps were stable, but the proportion and stability of journey-dependent place fields declined. In the altered environment, overall performance was strongly impaired, new firing maps were unstable, and stable proportions of journey-dependent place fields were maintained. In both tasks, memory errors were accompanied by a decline in journey codes. The different dynamics of place and journey coding suggest that they reflect separate mechanisms and contribute to distinct memory computations. Stable place fields may represent familiar relationships among environmental features that are required for consistent memory performance. Journey-dependent activity may correspond with goal-directed behavioral sequences that reflect expectancies that generalize across environments. The complementary signals could help link current events with established memories, so that familiarity with either a behavioral strategy or an environment can inform goal-directed learning.

In this paper, I read Vanessa’s journey to know herself as a form of edgework, which in sociology is a term for when...... we in our leisure time perform extreme, exciting and dangerous activities that take us beyond the limits of safety. In sport sociology, ‘edgework’ is when participants ‘work’ the edge of danger (Laurendeau, 2008). Whether in sport or fiction, ‘edgework’ can both challenge social rules and facilitate...

Quo Vadis, Homo Viator? / Journeys in Jože Hradil’s Faceless Pictures

2015-12-01

Full Text Available In Jože Hradil’s Faceless Pictures [Slike brez obrazov] the characters go astray or get into the attraction of adventures and set off for a journey. The spiritual and identity shifts can be interpreted along these eternal human desires as well. A patchwork of remembering and forgetting, the internal journeys of identity preservation, spontaneous or forced assimilation, tolerance and all kinds of politics-induced human deformations are depicted in the novel. The text traces the roles of the journey defined by Jean Chevalier and Alain Gheerbrant such as the search for justice, peace, immortality and finding the spiritual center. This study examines how the concrete physical journey changes into an internal road determining the evolution of personality.

Long Journey Travel to Tourist Destination: A Review Paper

Directory of Open Access Journals (Sweden)

Shahrin Norkamaliah

2014-01-01

Full Text Available Tourists are now more open in selecting tourist destination. The number of holiday trips were growing rapidly. There were various promotions available to attract tourists to travel either within or outside the country. Travel distance is not an obstacle for tourists to travel, regardless of local and foreign destination. This study will be conducted to identify the motivation of long journey travel that involves push and pull factors. The long journey involves distance, cost and the type of transportation used to get to the destination. For this purpose a comprehensive review and discussion on previous sources which involved a variety of secondary data sources will be used to meet every need of the study objectives. The finding showed that the travel distance was dependent on the motivation for tourists to travel and the type of transport they want to use. Mode of transport used has advantages and disadvantages for long journey travel depending on traveller choice.

Flight range, fuel load and the impact of climate change on the journeys of migrant birds

Sheard, Catherine; Butchart, Stuart H. M.

2018-01-01

Climate change is predicted to increase migration distances for many migratory species, but the physiological and temporal implications of longer migratory journeys have not been explored. Here, we combine information about species' flight range potential and migratory refuelling requirements to simulate the number of stopovers required and the duration of current migratory journeys for 77 bird species breeding in Europe. Using tracking data, we show that our estimates accord with recorded journey times and stopovers for most species. We then combine projections of altered migratory distances under climate change with models of avian flight to predict future migratory journeys. We find that 37% of migratory journeys undertaken by long-distance migrants will necessitate an additional stopover in future. These greater distances and the increased number of stops will substantially increase overall journey durations of many long-distance migratory species, a factor not currently considered in climate impact studies.

A journey with Fred Hoyle

CERN Document Server

Wickramasinghe, Chandra

2013-01-01

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.Two new chapters plus revisions to the other chapters bring the book up to date and thus make it more relevant, just as recent findings mesh with many of the ideas that had their origin in the first edition. ...

Goethe in the Hall and His Journeys in Printed Rome

Directory of Open Access Journals (Sweden)

Victor Plahte Tschudi

2015-12-01

Full Text Available The article focuses on graphic reproductions in Johann Wolfgang von Goethe’s 'Italian Journey'. This travel account gives a clear sense of how important prints were as part of Goethe’s education and preparation for the encounter with classical Roman monuments. As the text itself was edited and rewritten thirty to forty years after the journey itself, however, prints also became crucial in the attempt to remember that journey. In other words, the author of the 'Journey', in contrast to the youthful traveler, no longer sees engravings of Rome, but Rome through engravings. The discussion takes as a point of departure Goethe’s vast collection of prints, still kept in Weimar. Measured up against the references in the travel journal, prints not only reflected his impression of monuments, but also structured those impressions, as the elderly man looks back and reassembles his memories to make an official account of his life. However, it is too easy to ascribe this reliance on prints to a fading memory — on the contrary. As he grows into old age, Goethe’s idea of graphic reproduction evolves in parallel with his increasingly refined theories of nature. His growing preference for prints depicted as ruins reflects the aging author’s own sense of change and transformation.

"The Matrix": An allegory of the psychoanalytic journey.

Science.gov (United States)

Mischoulon, David; Beresin, Eugene V

2004-01-01

"The Matrix" has been a huge commercial and critical success and has spawned a series of books and essays exploring the philosophical and religious themes in the story. The authors propose is that "The Matrix" can be interpreted as an allegory for an individual's journey into spiritual and mental health, achieved by overcoming one's intrapsychic conflicts with the help of psychodynamic psychotherapy or psychoanalysis. Neo's story parallels the journey undertaken by the individual who chooses to enter psychotherapy and illustrates several themes of analytic psychotherapy, its benefits, and liabilities. The movie may therefore serve as a teaching tool for psychiatric residents about the goals, functions, and intricacies of psychodynamic psychotherapy.

PREFACE: A Stellar Journey A Stellar Journey

Asplund, M.

2008-10-01

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

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

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.

2015-09-01

Full Text Available This study was conducted to examine the effects on weight loss (WL, residual yolk (RY utilization and serum biochemical parameters of transport distance (TD in newly hatched broiler chicks. Just after hatching, 200 Ross 308 broiler chicks were traveled over 1000 km. At hatchery and after 200, 400, 600, 800 and 1000 km journey, a random sample of 20 birds were killed for blood collection, WL and yolk weight assessment. Live weight decreased linearly by 0.42 and 0.48 g per 100 km of journey in males and female chicks, respectively. Yolk sac residual utilized by 0.071 and 0.069 g per 100 km of travel in males and females chicks, respectively, over journey distances up to 800 km. Extended journey from 800 to 1000 km caused a great decline of 0.51 and 0.58 g per 100 km in yolk weight in male and female chicks, respectively. Serum Ca concentration reduced in TDs up to 400 km, then increased for longer journeys (P<0.05. Over 1000 km journey, serum GLU level of 196.24 mg/dL at hatchery was decreased to 117.31 mg/dL at the end of journey. Serum urea, uric acid and cholesterol concentrations were increased with the extended TDs (P<0.05. In conclusion increasing transportation distance causes intensified physiological stress in broiler chicks with varying effect on different stress indicators. Stress indicators in newly hatched chicks in transit may differ from those proposed for replaced chicks and the broiler chicken at later ages.

Geosciences help to protect human health: estimation of the adsorbed radiation doses while flight journeys, as important step to radiation risk assessment

Science.gov (United States)

Chernov, Anatolii; Shabatura, Olexandr

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

Weak signal detection: A discrete window of opportunity for achieving 'Vision 90:90:90'?

Science.gov (United States)

Burman, Christopher J; Aphane, Marota; Delobelle, Peter

2016-01-01

UNAIDS' Vision 90:90:90 is a call to 'end AIDS'. Developing predictive foresight of the unpredictable changes that this journey will entail could contribute to the ambition of 'ending AIDS'. There are few opportunities for managing unpredictable changes. We introduce 'weak signal detection' as a potential opportunity to fill this void. Combining futures and complexity theory, we reflect on two pilot case studies that involved the Archetype Extraction technique and the SenseMaker(®) Collector(™) tool. Both the piloted techniques have the potentials to surface weak signals--but there is room for improvement. A management response to a complex weak signal requires pattern management, rather than an exclusive focus on behaviour management. Weak signal detection is a window of opportunity to improve resilience to unpredictable changes in the HIV/AIDS landscape that can both reduce the risk that emerges from the changes and increase the visibility of opportunities to exploit the unpredictable changes that could contribute to 'ending AIDS'.

Comack, Margret Tannis

2012-01-01

Understanding leadership from the inside out was a journey that spanned a 40-year career in health care. This article describes an individual's journey of becoming an effective executive leader using the LEADS in a caring environment--capabilities framework. This framework was recently developed in Canada and is now used broadly to understand the complexity and depth of health care leadership skills and challenges. The author utilizes the framework to explore leadership skill development from a personal perspective to a broader system transformation level. Challenges and successes along this journey are included to highlight the manner in which leadership evolves with experience, time, and determination. A retrospective view of a successful career in health care provides the model for others to consider a similar career path using a theoretical base and a thoughtful process of personal development.

estimate a mean ‘reliability ratio’ (ratio of the value of standard deviation of journey time to the value of scheduled journey time) of 2.07, against a median of 0.85. The properties of the distribution of the reliability ratio suggest a predominant behaviour of aversion to journey time risk.......Within the broad area of probabilistic modelling of individual discrete choice, we develop three strands of discussion. First, we outline a theoretical framework for the modelling of individual discrete choice under risk, distinguishing between three specific sources of randomness; in preference...... orderings, in outcomes, and in attribute tastes. Second, we apply this theoretical modelling framework to the domain of journey time risk (or ‘reliability’), a subject which has acquired prominence in the transportation policies of many countries.

Highlights: Black-Right-Pointing-Pointer In this paper, we review the recent progress on the NSTX lithium research. Black-Right-Pointing-Pointer We summarize positive features of lithium effects on plasma. Black-Right-Pointing-Pointer We also point out unresolved issues and unanswered questions on the lithium research. Black-Right-Pointing-Pointer We describe a possible closed liquid lithium divertor tray concept. Black-Right-Pointing-Pointer We note opportunities and challenges of lithium applications for magnetic fusion. - Abstract: Lithium wall coating techniques have been experimentally explored on National Spherical Torus Experiment (NSTX) for the last six years. The lithium experimentation on NSTX started with a few milligrams of lithium injected into the plasma as pellets and it has evolved to a dual lithium evaporation system which can evaporate up to {approx}160 g of lithium onto the lower divertor plates between re-loadings. The unique feature of the NSTX lithium research program is that it can investigate the effects of lithium coated plasma-facing components in H-mode divertor plasmas. This lithium evaporation system has produced many intriguing and potentially important results. In 2010, the NSTX lithium program has focused on the effects of liquid lithium divertor (LLD) surfaces including the divertor heat load, deuterium pumping, impurity control, electron thermal confinement, H-mode pedestal physics, and enhanced plasma performance. To fill the LLD with lithium, 1300 g of lithium was evaporated into the NSTX vacuum vessel during the 2010 operations. The routine use of lithium in 2010 has significantly improved the plasma shot availability resulting in a record number of plasma shots in any given year. In this paper, as a follow-on paper from the 1st lithium symposium [1], we review the recent progress toward developing fundamental understanding of the NSTX lithium experimental observations as well as the opportunities and associated R and D required

The mythic structure in the black dome of the Haftpeikar: Study of Hero's journey in the first dome

Full Text Available Abstract In this paper the Vogler Hero's journey is used for analyzing the mythic structures and hero's journey of the first dome of the Haftpeikar. Vogler Released his founds in the Writer's Journey book. This book that is really dependent on Campbell's Single Myth Theory is a practical guidance for script writing and review of that. The levels of the hero's journey in his book are include: The normal world, invitation to the story, reject the invitation, visit the mentor, passing the first gate, the exams, the allies, the enemies, qualifying to the deepest cave, trial, the reward, the road back, resurrection, return with the elixir.  In this paper, at first the properties of each level of the hero's journey theory are matching with the journey's levels in the black dome story. After that seven useful archetypes including hero, mentor, threshold guardian, herald, shape shifter, the shadow and trickster, are determined in the text.  Black dome has several journeys' cycles. Journey's that are seen in this dome are: (Bahram's journey: A part of the internal journey of Bahram in black dome. (The king's maid journey: Internal journey of the king's maid that wears black clothes after hearing the story. (King of black clothes' journey: The king's journey to the Madhooshan city for exploring the mystery of the black alien. (The reader's journey: This internal journey belongs to the readers of the first dome that learn their lessons through traveling to the character's world. (Nezami's journey: The Nezami's internal journey with composing the text. Checking the reader's journey and black dome's composer is out of this text. While the first and second journey just saying some parts, the black king has completer levels and for affecting on the other journeys is the most important story of the first dome. Therefore at first we check the black king story and we explain the other journeys.  The goal of this paper in addition to the usage of the vogler

Peters, C.; Hornberger, G. M.; Machado, M.

2017-12-01

Academics are encouraged to integrate their environmental research with education and societal outreach, but the methods of doing so can be transient and insubstantial. Here, we use a children's book to create a sustainable relationship with vulnerable communities in Bangladesh. Farzana's Journey is a children's book based on current multidisciplinary Vanderbilt University research on the coupling and coevolution of the physical and human systems in coastal Bangladesh. Written, illustrated, and freely distributed in the Bengali-language, the book is a place-based tool to teach rural Bangladesh communities about the natural world and disseminate our scientific findings. The narrative follows a young girl, Farzana, who must walk a long distance to fetch her family's water. Her usual journey develops into an adventure as she meets a variety of animal characters, who relay a story about her ever-changing environment and the subsequent human adaptation. After exploring environmental topics, such as geomorphology, water availability, and climate, Farzana appreciates the uniqueness of her local environment and the adaptations of her ancestors and future generations. Through the development and distribution of the book, we encouraged dialogue, collaboration, and public outreach with scientists, artists, and students concerned with enhancing educational and social opportunity in rural communities. We also ensure a tangible tie through the book itself after the culmination of the research project. The book achieves the primary goal of sparking children's curiosity in the local environment, while also demonstrating an effective means for sustainable educational outreach with impoverished, remote communities.

We will not cover here the many and fundamental contributions from microbial genetics and in vitro biochemistry. Rather, in this journey, we will emphasize the interplay between microscopy development culminating on super resolution fluorescence microscopy (i.e., nanoscopy) and digital image analysis and its impact on our understanding of DNA duplication. We will interlace the journey with landmark concepts and experiments that have brought the cellular DNA replication field to its present state.

Buildings SMI 2 and SDI 2 are currently a big blue construction at the end of the Meyrin site. When they are finished, in 2003, they will be the departure point from where the magnets for the LHC will be lowered down into the tunnel. View of the new building at the end of the Meyrin site. If you live in neighbouring France, you have probably noticed a new blue steel construction that has changed the view from Saint Genis Pouilly since last March. It's the first of two contiguous buildings, SMI 2 and SDI 2, which will make it possible to prepare and lower the 1232 dipole magnets, the 400 short straight sections and some 60 insertion magnets down into the TI2 tunnel, and from there, to their final location in the LHC tunnel. According to Paul Faugeras, Technical Co-ordinator for the LHC machine, 'the installation of the magnets will start in early 2004, and hopefully everything will be done by October 2006'. The first part of the magnets' journey will take place on surface. The 15 metre-long dipole magnets a...

The chondrocytic journey in endochondral bone growth and skeletal dysplasia.

Science.gov (United States)

Yeung Tsang, Kwok; Wa Tsang, Shun; Chan, Danny; Cheah, Kathryn S E

2014-03-01

The endochondral bones of the skeleton develop from a cartilage template and grow via a process involving a cascade of chondrocyte differentiation steps culminating in formation of a growth plate and the replacement of cartilage by bone. This process of endochondral ossification, driven by the generation of chondrocytes and their subsequent proliferation, differentiation, and production of extracellular matrix constitute a journey, deviation from which inevitably disrupts bone growth and development, and is the basis of human skeletal dysplasias with a wide range of phenotypic severity, from perinatal lethality to progressively deforming. This highly coordinated journey of chondrocyte specification and fate determination is controlled by a myriad of intrinsic and extrinsic factors. SOX9 is the master transcription factor that, in concert with varying partners along the way, directs the different phases of the journey from mesenchymal condensation, chondrogenesis, differentiation, proliferation, and maturation. Extracellular signals, including bone morphogenetic proteins, wingless-related MMTV integration site (WNT), fibroblast growth factor, Indian hedgehog, and parathyroid hormone-related peptide, are all indispensable for growth plate chondrocytes to align and organize into the appropriate columnar architecture and controls their maturation and transition to hypertrophy. Chondrocyte hypertrophy, marked by dramatic volume increase in phases, is controlled by transcription factors SOX9, Runt-related transcription factor, and FOXA2. Hypertrophic chondrocytes mediate the cartilage to bone transition and concomitantly face a live-or-die situation, a subject of much debate. We review recent insights into the coordination of the phases of the chondrocyte journey, and highlight the need for a systems level understanding of the regulatory networks that will facilitate the development of therapeutic approaches for skeletal dysplasia.

The health care journeys experienced by people with epilepsy in Ireland: what are the implications for future service reform and development?

LENUS (Irish Health Repository)

Varley, J

2012-02-01

Opportunities exist to significantly improve the quality and efficiency of epilepsy care in Ireland. Historically, epilepsy research has focused on quantitative methodologies that often fail to capture the invaluable insight of patient experiences as they negotiate their health care needs. Using a phenomenological approach, we conducted one-to-one interviews with people with epilepsy, reporting on their understanding of their health care journey from onset of symptoms through to their first interaction with specialist epilepsy services. Following analysis of the data, five major themes emerged: delayed access to specialist epilepsy review; uncertainty regarding the competency and function of primary care services; significant unmet needs for female patients with epilepsy; disorganization of existing epilepsy services; and unmet patient information needs. The findings reveal important insights into the challenges experienced by people with epilepsy in Ireland and identify the opportunities for future service reorganization to improve the quality and efficiency of care provided.

On 21 January the first US-built LHC magnet arrived at CERN, after a journey of 6000 km by land and sea, an event hailed on both sides of the Atlantic. This 10-m long, 4.7-tonne dipole magnet was manufactured over a period of nine months by Brookhaven National Laboratory (BNL). Single-aperture magnets of this type will be installed on either side of the ALICE and LHCb experiments and will deviate the beams in order to provoke their interaction and subsequent separation. Brookhaven will be supplying 19 other dipoles for the insertion regions, including four of the same type as the one which has just arrived. «These magnets are based on a technology developed by Brookhaven Laboratory for its own RHIC accelerator,» explains Ranko Ostojic. LHC Project Leader Lyn Evans adds «our Brookhaven colleagues have done a fantastic job in completing the USA's first superconducting magnet for the LHC to specification and on schedule.

Exploring the requirements for multimodal interaction for mobile devices in an end-to-end journey context.

Science.gov (United States)

Krehl, Claudia; Sharples, Sarah

2012-01-01

The paper investigates the requirements for multimodal interaction on mobile devices in an end-to-end journey context. Traditional interfaces are deemed cumbersome and inefficient for exchanging information with the user. Multimodal interaction provides a different user-centred approach allowing for more natural and intuitive interaction between humans and computers. It is especially suitable for mobile interaction as it can overcome additional constraints including small screens, awkward keypads, and continuously changing settings - an inherent property of mobility. This paper is based on end-to-end journeys where users encounter several contexts during their journeys. Interviews and focus groups explore the requirements for multimodal interaction design for mobile devices by examining journey stages and identifying the users' information needs and sources. Findings suggest that multimodal communication is crucial when users multitask. Choosing suitable modalities depend on user context, characteristics and tasks.

To understand the journey of advanced prostate cancer patients for supporting development of an innovative patient journey browser. Prostate cancer is one of the common cancers in Australia. Due to the chronic nature of the disease, it is important to have effective disease management strategy and care model. Multi-disciplinary care is a well-proven approach for chronic disease management. The Multi-disciplinary team (MDT) can function more effectively if all the required information is available for the clinical decision support. The development of innovative technology relies on an accurate understanding of the advanced prostate cancer patient's journey over a prolonged period. This need arises from the fact that advanced prostate cancer patients may follow various treatment paths and change their care providers. As a result of this, it is difficult to understand the actual sources of patient's clinical records and their treatment patterns. The aim of the research is to understand variable sources of clinical records, treatment patterns, alternative therapies, over the counter (OTC) medications of advanced prostate cancer patients. This study provides better and holistic understanding of advanced prostate cancer journey. The study was conducted through an on-line survey developed to seek and analyse the responses from the participants. The on-line questionnaire was carefully developed through consultations with the clinical researchers at the Australian Prostate Cancer Research Centre-Queensland, prostate cancer support group representatives and health informaticians at the Australian E-Health Research Centre. The non-identifying questionnaire was distributed to the patients through prostate cancer support groups in Queensland, Australia. The pilot study was carried out between August 2010 and December 2010. The research made important observations about the advanced prostate cancer journey. It showed that General Practitioner (GP) was the common source of

In celebration of the anniversary of the Journal of Applied Psychology ( JAP ), we take a hundred-year journey to examine how the science of cross-cultural industrial/organizational psychology and organizational behavior (CCIO/OB) has evolved, both in JAP and in the larger field. We review broad trends and provide illustrative examples in the theoretical, methodological, and analytic advances in CCIO/OB during 4 main periods: the early years (1917-1949), the middle 20th century (1950-1979), the later 20th century (1980-2000), and the 21st century (2000 to the present). Within each period, we discuss key historical and societal events that influenced the development of the science of CCIO/OB, major trends in research on CCIO/OB in the field in general and JAP in particular, and important milestones and breakthroughs achieved. We highlight pitfalls in research on CCIO/OB and opportunities for growth. We conclude with recommendations for the next 100 years of CC IO/OB research in JAP and beyond.

"THE LANGUAGE OF THE HIGHEST TRUTH...": PUSHKIN'S ATTITUDE TO THE GOSPEL IN HIS "JOURNEY TO ARZRUM"

Directory of Open Access Journals (Sweden)

Irina Leonidovna Bagration-Mukhraneli

2013-11-01

Full Text Available The article deals with the Christian code of Alexander Pushkin’s Journey to Arzrum, which is a style forming factor for the whole story, featuring a large thematic diversity. The genre of this book is similar to Old Russian pilgrimage stories. It includes an ethnographic sketch, a battle, Oriental and situational impressions of moving in space. All these are balanced with the biblical names and allusions, as well as the existential experience of the sacred. According to Pushkin, the Gospel is the foundation for real politics and an effective means of annexation of the Caucasus to the Russian Empire. Journey to Arzrum had an impact on the image of the war created by Leo Tolstoy in his War and Peace, as well as on the creation of such pilgrimage stories of the 20th century as A Journey to Armenia by Osip Mandelshtam and A Journey to Mount Athos by Boris Zaytsev.

organization can take to become health literate. CHS provides an example of how, even when the most senior leadership drives the organization to become health literate, continued progress requires constant reinvigoration. At Intermountain Healthcare, the push to become a health literate organization was the natural consequence of organizational adoption of a model of shared accountability that necessitated patient engagement for its success. Northwell Health, on the other hand, provides a model of how a persistent champion can elevate health literacy to become a system priority and how system-wide policies and procedures can advance effective communication across language differences, health literacy, and cultures. The profiles of the three systems make clear that the opportunities for health literacy improvement are vast. Success depends on the presence of a perfect storm of conditions conducive to transformational change. This chapter ends with lessons learned from the experiences of health literacy pioneers that may be useful to organizations embarking on the journey. The journey is long, and there are bumps along the road. Nonetheless, discernable progress has been made. While committed to transformation, organizations seeking to be health literate recognize that it is not a destination you can ever reach. A health literate organization is constantly striving, always knowing that further improvement can be made. PMID:28972519

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.

2012-01-01

The tyrosine kinase inhibitor (TKI) imatinib has improved outcomes for patients with unresectable or metastatic gastrointestinal stromal tumors (GIST), and for patients receiving adjuvant therapy following GIST resection. This qualitative study explored the experiences and emotions of patients through GIST diagnosis, treatment initiation, disease control, and in some patients, loss of response and therapy switch. Ethnographic investigations were conducted, including semi- structured qualitative interviews of patients with resected or metastatic/unresectable GIST and their caregivers, from Canada (n = 15); the United States (n = 10); and Brazil, France, Germany, Russia, and Spain (n = 5 each). Some interviewees also kept 7-day photo journals. Responses were qualitatively analyzed to identify gaps and unmet needs where communication about disease, treatments, and adherence could be effective. Patients shared common experiences during each stage of disease management (crisis, hope, adaptation, new normal, and uncertainty). Patients felt a sense of crisis during diagnosis, followed by hope upon TKI therapy initiation. Over time, they came to adapt to their new lives (new normal) with cancer. With each follow-up, patients confronted the uncertainty of becoming TKI resistant and the possible need to switch therapy. During uncertainty many patients sought new information regarding GIST. Cases of disease progression and drug switching caused patients to revert to crisis and restart their emotional journey. Patients with primary or unresectable/metastatic GIST shared similar journeys, especially regarding uncertainty, although differences in the scope and timing of phases were observed. Strategies patients used to remain adherent included obtaining family support, setting reminder mechanisms, taking medicine at routine times, and storing medicine in prominent places. Physicians and support staff can manage patient expectations and encourage adherence to therapy, which may

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. © 2015 Wiley Publishing Asia Pty Ltd.

The NHS has a target of cutting its carbon dioxide (CO2) emissions by 80% below 1990 levels by 2050. Travel comprises 17% of the NHS carbon footprint. This carbon footprint represents the total CO2 emissions caused directly or indirectly by the NHS. Patient journeys have previously been planned largely without regard to the environmental impact. The potential contribution of 'avoidable' journeys in primary care is significant. To investigate the carbon footprint of patients travelling to and from a general practice surgery, the issues involved, and potential solutions for reducing patient travel. A mixed methods study in a medium-sized practice in Yorkshire. During March 2012, 306 patients completed a travel survey. GIS maps of patients' travel (modes and distances) were produced. Two focus groups (12 clinical and 13 non-clinical staff) were recorded, transcribed, and analysed using a thematic framework approach. The majority (61%) of patient journeys to and from the surgery were made by car or taxi; main reasons cited were 'convenience', 'time saving', and 'no alternative' for accessing the surgery. Using distances calculated via ArcGIS, the annual estimated CO2 equivalent carbon emissions for the practice totalled approximately 63 tonnes. Predominant themes from interviews related to issues with systems for booking appointments and repeat prescriptions; alternative travel modes; delivering health care; and solutions to reducing travel. The modes and distances of patient travel can be accurately determined and allow appropriate carbon emission calculations for GP practices. Although challenging, there is scope for identifying potential solutions (for example, modifying administration systems and promoting walking) to reduce 'avoidable' journeys and cut carbon emissions while maintaining access to health care.

Journey to the center of the galaxy

Chaisson, E.

1980-01-01

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

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

Landau, Mark J; Oyserman, Daphna; Keefer, Lucas A; Smith, George C

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).

A short review is made of molecular magnetism, trying to discuss what is alive and well, with perspectives for the future. All the main fields of activity are mentioned, ranging from the so-called spin cross-over systems to the quest for organic (molecular) ferromagnets. Particular attention is devoted to some of the recent advances in these fields, highlighting also the opportunities for the development of applications. Low dimensional magnets are perhaps the best opportunity to use molecules, and the status of single-molecule and single chain magnets is discussed. The last part is devoted to the organization of magnetic molecules and to the development of techniques which allow to measure the magnetic properties of thin layers and, in perspective, of single molecules.

2018-05-01

To explore how adult, child and mental health nursing and midwifery students, selected using multiple mini interviews, describe their 'values journey' following exposure to the clinical practice environment. Values based recruitment (VBR) incorporates assessment of healthcare students' personal values using approaches like multiple mini interviews. Students' experience of adjustment to their values during their programme is conceptualized as a 'values journey'. The impact of VBR in alleviating erosion of personal values remains unclear. A cross-professional longitudinal cohort study was commenced at one university in England in 2016 with data collection points at the end of years one, two and three. Non-probability consecutive sampling resulted in 42 healthcare students (8 adult, 8 child and 9 mental health nursing and 17 midwifery students) taking part. Six semi-structured focus groups were conducted at the end of participants' Year One (DC1). Data analysis incorporated inductive and deductive approaches in a hybrid synthesis. Participants described a 'values journey' where their values, particularly communication, courage and wanting to make a difference, were both challenged and retained. Participants personal journeys also acknowledged the: 'courage it takes to use values'; 'reality of values in practice' and 'need for self-reflection on values'. A 'values journey' may begin early in a healthcare student's education programme. This is important to recognize so that appropriate interventions designed to support students in higher education and clinical practice can be implemented. The values incorporated in VBR should be continually evaluated for fitness for purpose. © 2017 John Wiley & Sons Ltd.

Hansen, Dana; Sheehan, Denice K; Stephenson, Pam

2017-02-02

Illness blogs are a way seriously ill people communicate publicly about their illness journey. As communication about serious illness increases on social media, it is important to evaluate how this affects the family caregiver. However, identifying and accessing family caregivers remains challenging, especially via social media. The aim of this article is to report the opportunities, challenges and lessons learned from using social media to recruit family caregivers. Recruitment methods included posting study invitations on illness blogs, advertising through Facebook and placing study fliers in the community. Using social media to recruit was inexpensive and provided a wide geographical reach. One important finding was discovering the importance of using language in the recruitment materials that family caregivers could identify with to help deem themselves as eligible to participate in the study.

Integrated travel network model for studying epidemics: Interplay between journeys and epidemic

Ruan, Zhongyuan; Wang, Chaoqing; Ming Hui, Pak; Liu, Zonghua

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.

Measuring the Impact of Online Evidence Retrieval Systems using Critical Incidents & Journey Mapping.

Science.gov (United States)

Westbrook, Johanna I; Coiera, Enrico W; Braithwaite, Jeffrey

2005-01-01

Online evidence retrieval systems are one potential tool in supporting evidence-based practice. We have undertaken a program of research to investigate how hospital-based clinicians (doctors, nurses and allied health professionals) use these systems, factors influencing use and their impact on decision-making and health care delivery. A central component of this work has been the development and testing of a broad range of evaluation techniques. This paper provides an overview of the results obtained from three stages of this evaluation and details the results derived from the final stage which sought to test two methods for assessing the integration of an online evidence system and its impact on decision making and patient care. The critical incident and journey mapping techniques were applied. Semi-structured interviews were conducted with 29 clinicians who were experienced users of the online evidence system. Clinicians were asked to described recent instances in which the information obtained using the online evidence system was especially helpful with their work. A grounded approach to data analysis was taken producing three categories of impact. The journey mapping technique was adapted as a method to describe and quantify clinicians' integration of CIAP into their practice and the impact of this on patient care. The analogy of a journey is used to capture the many stages in this integration process, from introduction to the system to full integration into everyday clinical practice with measurable outcomes. Transcribed interview accounts of system use were mapped against the journey stages and scored. Clinicians generated 85 critical incidents and one quarter of these provided specific examples of system use leading to improvements in patient care. The journey mapping technique proved to be a useful method for providing a quantification of the ways and extent to which clincians had integrated system use into practice, and insights into how information

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, pcar 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.

What is the universe really made of? How do we know? Follow the map of the invisible to find out... Over the last sixty years, scientists around the world have worked together to explore the fundamental constituents of matter, and the forces that govern their behaviour. The result, so far, is the ‘Standard Model’ of elementary particles: a theoretical map of the basic building blocks of the universe. With the discovery of the Higgs boson in 2012, the map as we know it was completed, but also extended into strange new territory. A Map of the Invisible is an explorer’s guide to the Standard Model and the extraordinary realms of particle physics. After shrinking us down to the size of a sub-atomic particle, pioneering physicist Jon Butterworth takes us on board his research vessel for a journey in search of atoms and quarks, electrons and neutrinos, and the forces that shape the universe. Step by step, discovery by discovery, we journey into the world of the unseen, from the atom to black holes and dark ...

Returning to work: The cancer survivor’s transformational journey of adjustment and coping

Directory of Open Access Journals (Sweden)

Antoni Barnard

2016-11-01

Full Text Available The aim of this study was to explore cancer survivors’ return to work (RTW experience with a specific focus on the adjustment and coping process underlying their journey. The study was conducted in the Southern Cape, South Africa, with eight cancer survivors having returned to work following successful treatment of various types of cancer. Unstructured interviews were conducted and data were analysed following the principles of hermeneutic phenomenological reflection and analysis. Four themes emerged, representing the changing adjustment responses and coping during the RTW journey. Participants evolve from being overwhelmed with emotions and applying avoidant coping to seeking understanding and positive affectivity in their attempt to comprehend the reality of their situation. Participants’ external locus of control change to a more active approach and problem-solving orientation, demonstrating a need to take control and responsibility. Ultimately, adjustment and coping become most constructive when cancer survivors resolve to re-assess life and self through meaning-making, resulting in renewed appreciation of life, appropriate life style changes, and regained confidence in their relational role. A process perspective is proposed to facilitate an understanding of, and working with, cancer survivors’ transition through the RTW journey towards optimal coping phases.

2 Cases of Bullosis Diabeticorum following Long-Distance Journeys by Road: A Report of 2 Cases

2012-01-01

Full Text Available Background. Bullosis diabeticorum is a distinct, spontaneous, noninflammatory, and blistering condition of acral skin that is unique to diabetics. It is rare. Exact aetiopathogenesis is not known, but many attributed peripheral neuropathy as a potent risk factor, others hypothesized the role of trauma, UV light, and nephropathy. Aim. To present cases of bullosis diabeticorum following long-distance journeys by road. Methods. History and physical examinations were done on 2 diabetics who presented with bilateral feet bullae following a long journey. Biopsy of a circumferential area of the bullae including adjoining apparently normal skin was done. Results. Features of peripheral neuropathy were noted. One developed digital gangrene without features of peripheral vascular disease. Culture of aspirate from a bullae yielded Staphylococcus aureus. Tissue biopsy showed hyperkeratotic focally acanthotic pigmented epidermis with subcorneal separation of the granular layer of the epidermis by aggregates of viable and nonviable polymorphs and lymphocytes. There is mild acantholysis of the epidermis, and a fibrocollagenous dermis which is moderately infiltrated by lymphocytes. Conclusion. Long journeys by road is a strong factor in the aetiopathogenesis of bullosis diabeticorum on a background of peripheral neuropathy. Diabetics especially those with peripheral neuropathy should be cautious while traveling long journeys by road.

Understanding the requirements of geographical data for blind and partially sighted people to make journeys more independently.

Science.gov (United States)

Chandler, Edward; Worsfold, John

2013-11-01

Previous research has highlighted that blind and partially sighted people find various factors inhibit their abilities to make journeys. This paper proposes that the lack of accurate, appropriate and usable geographical data is one of the reasons for this and these can be tracked back to core human factors issues such as situational awareness, mental workload and environmental ergonomics. Following a review of applicable literature a hierarchical task analysis was performed to better understand the problems in terms of the complexity of various journey types and to identify the geographical data requirements in order to make successful journeys. The task analysis produced a number of results including highlighting four underlying principles which have an impact on the data requirements during any given journey. Finally the need for accessible and accurate geographical data requirements is introduced as a result of the literature review and the task analysis. These highlight the information required in order to facilitate more accessible travel for blind and partially sighted people by providing geographical information about their surroundings in a relevant, meaningful and usable way.

The study investigates the process of recovery for people diagnosed with personality disorder, a client group that suffers significant social exclusion known to impact on demand for health and other public services. It aims to examine efforts that attempt to reverse this social exclusion as an aspect of the recovery process. and The following study aims to (1) explore what recovery means to people with personality disorder; (2) develop a conceptual model of recovery in personality disorder; and (3) evaluate the contribution of the setting (The Haven) to recovery practice. The study uses a Participatory Action Research (PAR) design. Data was collected from 66 participants by focus groups and individual interviews. A map based on thematic analysis of data collected during the study is proposed of the recovery journey for people with this diagnosis, shown as a pyramid that represents a hierarchy of progress, from building trust through stages of recovery to social inclusion. The findings offer contributions to knowledge in terms of the service design and propose a new model of recovery in personality disorder. This is defined as a journey of small steps highlighting recovery as a process rather than a goal, leading to the emergence of the new concept of transitional recovery.

Full Text Available While facilitating the first practice development school for our local healthcare authorities in Nova Scotia, Canada, recently, I was simultaneously preparing for my second hip replacement. Focusing workshop participants on the principles of practice development, collaboration, inclusion and participation, I wondered if, in my upcoming journey through the healthcare system, I would experience the processes and outcomes we were promoting in the school. I would like to share this commentary as a reflection of my practice development experience as a patient. Overall, I received care that was inclusive and collaborative – as well as care that was provider focused and system driven. It goes without saying that as a patient, I felt valued when I was included and felt part of the team when my wishes and expectations were taken into consideration. For me, inclusion in care correlates with valuing that patient as a participant in their care journey, as set out by practice development principle 6 (Manley, McCormack and Wilson, 2008 (Table 1. My recent healthcare experience has led me to reflect further on the principles of practice development and its implications and challenges for local healthcare authorities. For example, my anaesthetist comes to mind as embodying practice development principles 2, 4, 6 and 8. The anaesthetist supported my wishes surrounding narcotics, and provided research- and practice-based evidence for each of his actions. Although the offering of additional narcotics is routine practice in hip surgery, I did not want this, so we discussed my expectations and developed a plan together that reflected my wishes. He actually chatted throughout the entire two-hour procedure. I was pleasantly surprised when he told me he provides care that focuses on the patient (practice development principle 1. Nevertheless, inconsistencies in the attention to person-centred practices across the microsystem reminded me that the system is not yet set

The transport of domestic animals by road can increase levels of stress and decrease meat quality, especially in unfavourable climates. The purpose of this study was to investigate the effect of journey duration and vertical position on the transport truck on some physiological indicators of stress and on instrumental meat quality parameters in commercial rabbits. In the summer months (June and July, 2003), 78 rabbits were subjected to either long (7 h) (LJ) or short (1 h) (SJ) journeys (3 replicates each, n = 6) between the farm and an abattoir in northern Spain. The position (top, middle, or bottom) occupied by the rabbits on the Multi-Floor cage Rolling Stand (MFRS) of the transport truck was recorded. Blood samples were collected at sticking and meat pH was measured at 24 h post-mortem (pH24). At 48 h post-mortem, samples of the M. longissimus dorsi were used to determine water-holding capacity (WHC) and instrumental tenderness using an INSTRON machine. The levels of corticosterone, glucose, lactate, and creatine kinase were slightly higher in LJ than in SJ samples, but the difference was not statistically significant (p MFRS showed higher levels (p < or = 0.05) of glucose and creatine kinase (middle), and corticosterone (bottom) than the rabbits located at the top floor. The pH 24 and WHC values of the SJ and LJ rabbits did not differ significantly. Journey length had a significant effect (p < or = 0.01) on meat tenderness. The meat from rabbits subjected to LJ had higher values of maximum stress and total toughness than did the SJ rabbits (p < or = 0.05). There were similar differences (p < or = 0.05) between LJ and SJ rabbits in their stress values of compression at 20% and 40% (measures of the tenderness of raw meat). In hot weather, the position on the transport truck appeared to have a greater effect on rabbit welfare than the duration of the journey.

Objective To provide an outcomes-evaluation of an intervention to strengthen professional nursing practice in Russian and Armenian hospitals. Design The Nursing Quality Improvement Initiative using Forces of Magnetism to develop professional nurse practice was implemented in four hospitals in Russia and Armenia. Cross-sectional survey data were collected at two time points from 840 nurses in wave 1 and 859 nurses in wave 2. Comparisons were undertaken between targeted units in each hospital compared to non-targeted units, and each hospital served as its own control in surveys that took place in year one and three of the demonstration. Methods Descriptive information on the nurse samples were derived from survey items. Changes in characteristics of nurse practice environments, nurse-reported patient care quality, and nurse burnout in Russia and Armenia, overall and separately for targeted and non targeted units, were tested using chi-square statistics and difference of means tests. Findings Practice environment features, such as nurses’ involvement in hospital affairs, better collegial relationships with physicians, more support for nursing care from administration, and continuity of nursing care improved after the intervention. Resource adequacy indicators did not change over the demonstration period. There were favorable changes in indicators of patient care quality, though differences in changes in targeted and non-targeted units were equivocal. Conclusions Changes consistent with evolving professional nursing practice were associated with program implementation. Forces of Magnetism appear to have the same potential for transforming nursing practice in countries with fewer resources as in wealthier Western countries. Clinical Relevance Magnet Recognition, an evidence-based best practice for improving the nursing care environment developed in Western countries was feasible to implement in countries with transitioning economies, limited resources, and truncated

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. 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. 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 recommendations at policy and industry meetings and healthcare

Narrating Science and Religion. Storytelling Strategies in Journey of the Universe

Directory of Open Access Journals (Sweden)

Nancy Menning

2016-12-01

Full Text Available While scientific and religious narratives use distinct discourse strategies to reach different audiences, the documentary film Journey of the Universe combines scientific and humanistic perspectives to narrate the origin and evolution of the universe, life on Earth, and human consciousness. This science-based mythic telling of the universe story foregrounds science to enhance the story’s plausibility while using mythic elements to invite an ethical response. We evaluate how this film blends scientific and mythic storytelling strategies to present a plausible story with moral force. Journey of the Universe presents an image of humanity as naturally emerging from an increasingly complex cosmos, capable of profound wonder, and poised to use its intellectual gifts to renew the face of the earth. We argue that narrative strategies aligning scientific content with the viewer’s personal experiences of nature are generally effective, and that the film’s focus on the local and terrestrial, even in the midst of the vastness of the cosmos, supports its ecological message.

Journey Through Intuition

Directory of Open Access Journals (Sweden)

Christina LEGREE

2010-12-01

Full Text Available In this article I wish to share how I learned about intuition through personal experiences and why it is important in education. Intuition is linked to epistemology, language, emotions, health, memory and involves the inner life of the person. For most of my life, I had very little understanding about intuition and deemed this phenomenon as useless in education. I started to learn about intuition as a result of my spouses catastrophic death. The grief I experienced precipitated a loss in my belief system and I felt a significant decrease in my ability to function in a logical or rational manner. My journey into intuition enabled me to forge a new way to live my life. I believe that each person has the ability to learn about intuition and how it can be useful in guiding ones life. The mainstream school system however fails to recognize intuition as a valid way of learning despite the research in this field. Students are therefore being given a partial education. Given this, I feel there is a serious problem which emerges if people are led to believe that the mainstream education system is offering students a complete education.

2014-01-01

This article focuses on a framework that will investigate the integration of two disparate methodologies: patient journey modelling and visual multi-agent simulation, and its impact on the speed and quality of knowledge translation to healthcare stakeholders. Literature describes patient journey modelling and visual simulation as discrete activities. This paper suggests that their combination and their impact on translating knowledge to practitioners are greater than the sum of the two technologies. The test-bed is ambulatory care and the goal is to determine if this approach can improve health services delivery, workflow, and patient outcomes and satisfaction. The multidisciplinary research team is comprised of expertise in patient journey modelling, simulation, and knowledge translation.

Accessing Creativity: Jungian Night Sea Journeys, Wandering Minds, and Chaos.

Science.gov (United States)

Rosen, Diane

2016-01-01

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.

In search of plutonium: A nonproliferation journey

Science.gov (United States)

Hecker, Siegfried

2010-02-01

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. )

To evaluate the effectiveness of the Acceptance Journeys social marketing campaign to reduce homophobia in the Black community in Milwaukee, Wisconsin. We assessed the campaign's effectiveness using a rolling cross-sectional survey. Data were collected annually online between 2011 and 2015. Each year, a unique sample of Black and White adults, aged 30 years and older, were surveyed in the treatment city (Milwaukee) and in 2 comparison cities that did not have antihomophobia campaigns (St. Louis, MO, and Cleveland, OH; for total sample, n = 3592). Black self-identification and Milwaukee residence were significantly associated with exposure to the campaign, suggesting successful message targeting. The relationship between exposure and acceptance of gay men was significantly mediated through attitudes toward gay men, perceptions of community acceptance, and perceptions of the impact of stigma on gay men, but not through rejection of stereotypes. This model accounted for 39% of variance in acceptance. This evidence suggests that the Acceptance Journeys model of social marketing may be a promising strategy for addressing homophobia in US Black communities.

Bormann, Lorraine; Abrahamson, Kathleen

2014-04-01

Nurse managers leadership behaviors influence the job satisfaction of staff nurses. Transformational leadership is 1 of the 5 components associated with the Magnet Recognition Program®. The aim of this study was to examine the relationship between staff nurse perception of nurse manager leadership behavior and staff nurse job satisfaction in a hospital on the Magnet® journey and the influence of nurse manager leadership style on staff nurse job satisfaction. A descriptive, correlational design using a self-report survey with convenience sampling was used for this quantitative research study. Staff nurses completed the Multifactor Leadership Questionnaire 5X Short Form, the Abridged Job Descriptive Index survey, and a demographic questionnaire. Pearson correlations and regression analyses were completed to explore the relationship and influence of nurse manager leadership style on staff nurse job satisfaction. Transformational and transactional leadership styles of nurse managers were positively related to staff nurse overall job satisfaction and satisfaction with opportunity for promotion. Passive-avoidant leadership style of nurse managers was negatively related to staff nurse satisfaction with work, promotion, supervision, and coworker. Satisfaction with nurse manager leadership was a positive influence on overall nurse job satisfaction when separately controlling for the influence of each leadership style. Transformational and transactional leadership styles should be taught and encouraged among nurse managers to positively influence the job satisfaction of staff nurses.

Brain-heart interactions: challenges and opportunities with functional magnetic resonance imaging at ultra-high field.

Science.gov (United States)

Chang, Catie; Raven, Erika P; Duyn, Jeff H

2016-05-13

Magnetic resonance imaging (MRI) at ultra-high field (UHF) strengths (7 T and above) offers unique opportunities for studying the human brain with increased spatial resolution, contrast and sensitivity. However, its reliability can be compromised by factors such as head motion, image distortion and non-neural fluctuations of the functional MRI signal. The objective of this review is to provide a critical discussion of the advantages and trade-offs associated with UHF imaging, focusing on the application to studying brain-heart interactions. We describe how UHF MRI may provide contrast and resolution benefits for measuring neural activity of regions involved in the control and mediation of autonomic processes, and in delineating such regions based on anatomical MRI contrast. Limitations arising from confounding signals are discussed, including challenges with distinguishing non-neural physiological effects from the neural signals of interest that reflect cardiorespiratory function. We also consider how recently developed data analysis techniques may be applied to high-field imaging data to uncover novel information about brain-heart interactions. © 2016 The Author(s).

A humanistic approach to paediatric radiation therapy – One family's journey

International Nuclear Information System (INIS)

Collier, David

2013-01-01

Purpose: To present a patient view of a treatment journey, highlighting the strengths and the weaknesses from that experience and recognising a potential for Advanced Practice on behalf of Radiation Therapists. The patient was aged 7 when diagnosed in December 2007 with an anaplastic ependymona tumour in the occipital lobe and had surgery to effect maximal tumour resection. The pathology of the tumour upon removal indicated that it was a Grade III anaplastic ependymoma some 3 cm across. In early 2008 the patient embarked on radiation therapy receiving 59.4 Gy over 33 treatments. This case was an inaugural patient for a novel intervention which aimed at reducing anxiety and helping the patient to cope with paediatric radiotherapy. The intervention was outstandingly successful and the diversionary activities within the treatment regime undoubtedly added to the effectiveness of the treatment. The patient maintained near normal daily activities missing only the first couple of hours of school each day during the treatment period. The paper will cover this from that patient's perspective and then report on the post treatment impact of that treatment. It will present the patient's view and outcomes in the evolution of the patient management process and improved healthcare. Results: The paper identifies the important role of communication and understanding amongst all members of the team, including the patient. It comments on the need to recognise the full range of options available and the best practice guidelines which could be adopted. Above it touches on the impact the adoption of all of these has on the patient treatment journey. It opens up the question of the appropriate mechanisms of involvement for the patient in this journey and the associated decision making surrounding this involvement, and this paper specifically comments on this. It identifies other professionals' world-wide who are working on elements of this approach. Conclusion: The paper will highlight

Takada, Yoshie

2017-08-01

The landscape architect Maggie Jencks felt that she wanted a place to "get herself back" when her breast cancer recurred and was told that she only had a few months remaining. Mr. Charles Jencks, her husband who fulfilled her wishes, opened the first "Maggie's Cancer Caring Centre" in Edinburgh in 1996. Masako Akiyama, the chief of Maggie's Tokyo found out about Maggie's Centre when she listened to a presentation from Andrew Anderson, the director of Maggie's Edinburgh, at an International Nursing Seminar in 2008. Masako Akiyama realized that support to "get back ones own power" is one of the important things. In addition, she felt that providing a "place" and "support" to patients and their families were predominant elements. When someone is diagnosed with cancer, the person gets a great shock and feels loneliness. Suddenly the person feels tomorrow will not come, every day becomes uncertain. These feelings affect their whole life such as enrollment, employment, loss of role, and change. They also affect people such as family, friends, colleagues, besides the person. Due to changes in treatment, the existential troubles that have been prolonged after the completion of the initial treatment appear. Cancer survivorship is called "Cancer journey"in the Maggie's flow. The cancer journey suddenly starts, when a person is diagnosed with cancer", without direction or a plan. Additionally, the "heart"is often left behind. To undertake the cancer journey, there are a lot of forks in the road that cannot turn back and they are urged to choose their path. "Where now ?"is a phrase in a pamphlet from Maggie's Centre, and the phrase shows that staff of Maggie's Centre can help cancer patient to recognize where they are in their Cancer journey. The Maggie's Centre has 2 important pillars: "building/environment"and "human support". As a "homely place" between hospital and my house, the building is "a healing space". Human support is provided free of charge and patients and

The Relationship Between Health Management and Information Behavior Over Time: A Study of the Illness Journeys of People Living With Fibromyalgia.

Science.gov (United States)

Chen, Annie T

2016-10-25

Over the course of a chronic illness, patients face many challenges, including understanding what is happening to them and developing an effective strategy for managing illness. While there is existing literature concerning how people seek health-related information and cope with chronic illnesses, there is a need for additional research on how information affects patients' understandings of their illness, and how changes in this understanding affect their health management strategies over time. This study examined how health management, information seeking, and information consumption and use processes are related throughout an illness. A diversified recruitment strategy involving multiple media channels was used to recruit participants for an interview study. During the interviews, participants were asked to draw an "illness journey" timeline. The data were analyzed using a qualitative approach drawn from Interpretative Phenomenological Analysis and Grounded Theory. The study identified four main health management features of illness journeys: onset, progression toward diagnosis, acceptance, and development of an effective management strategy. The study then focused on how information seeking changes over illness journeys, particularly in terms of a transition from active information seeking to monitoring with intermittent focused searching. Last, the paper describes the information consumption and use processes that patients engaged in throughout their journey. This study makes three important contributions to the field. First, it presents an integrated conceptualization of how health management and information behaviors are related on illness journeys. Second, it adds to our existing knowledge on health literacy and self-management of chronic illness. Third, the study has implications for health interface design.

This paper is about the intense experience of being in the hospital in a comatose state resulting from an aneurysm with a massive brain hemorrhage and two subsequent surgeries. The event begins with a premonition of what will happen from a street name. The experience of brain surgeries, along with the fine care of the nurses, left me with a truly memorable impression. This paper describes the various feelings and strong emotions that I experienced while in a comatose state. It suggests that a patient in a comatose state can exist in a deep state of emotions close to ecstasy. The paper concludes with gratefulness to all the people who followed me step by step on this journey.

The magnificent journey

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

Solar journey: The significance of our galactic environment for the heliosphere and earth

CERN Document Server

Frisch, Priscilla C

2006-01-01

Humans evolved when the Sun was in the great void of the Local Bubble. The Sun entered the present environment of interstellar clouds only during the late Quaternary. Astronomical data reveal these long and short term changes in our galactic environment. Theoretical models then tell us how these changes affect interplanetary particles, planetary magnetospheres, and the Earth itself. Cosmic rays leave an isotopic signature in the paleoclimate record that helps trace the solar journey through space. "Solar Journey: The Significance of Our Galactic Environment for the Heliosphere and Earth" lays the foundation for an interdisciplinary study of the influence of interstellar material on the solar system and Earth as we travel through the Milky Way Galaxy. The solar wind bubble responds dynamically to interstellar material flowing past the Sun, regulating interstellar gas, dust, and cosmic particle fluxes in the interplanetary medium and the Earth. Cones of interstellar gas and dust focused by solar gravity, the ma...

2015-01-01

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

Real innovations in medicine and science are historic and singular; the stories behind each occurrence are precious. At Molecular Medicine we have established the Anthony Cerami Award in Translational Medicine to document and preserve these histories. The monographs recount the seminal events as told in the voice of the original investigators who provided the crucial early insight. These essays capture the essence of discovery, chronicling the birth of ideas that created new fields of research; and launched trajectories that persisted and ultimately influenced how disease is prevented, diagnosed, and treated. In this volume, the Cerami Award Monograph is by Paul Nurse, Director, The Francis Crick Institute in London, UK. A visionary in the field of cell biology, this is the story of Dr. Nurse's scientific journey.

2016-01-01

While the recent Coalition government committed to some initiatives supporting the role of parents, relationships and the early years, there remains a lack of focus on fathers as a distinct policy area. This is reflected at local government level, as lead professionals for young fathers are rare and data on the number of young fathers in each local area are not routinely collected. Barnardo's was funded by the Department for Education in 2012, as part of the Family Strategic Partnership, to highlight the needs and experiences of young fathers in England, and the joint role of statutory and voluntary services in supporting them (fully reported by Barnardo's in Cundy, 2012). Based on selected case studies drawn from research and a range of practice organisations, this article presents the journeys of five young fathers and their experience of maternity services, children's centres, schools, housing services and the secure estate.

Electrochemical synthesis of CORE-shell magnetic nanowires

(Fe, Ni, CoFe) @ Au core-shell magnetic nanowires have been synthesized by optimized two-step potentiostatic electrodeposition inside self-assembled nanopores of anodic aluminium templates. The optimal electrochemical parameters (e.g., potential) have been firstly determined for the growth of continuous Au nanotubes at the inner wall of pores. Then, a magnetic core was synthesized inside the Au shells under suitable electrochemical conditions for a wide spectrum of single elements and alloy compositions (e.g., Fe, Ni and CoFe alloys). Novel opportunities offered by such nanowires are discussed particularly the magnetic behavior of (Fe, Ni, CoFe) @ Au core-shell nanowires was tested and compared with that of bare TM nanowires. These core-shell nanowires can be released from the template so, opening novel opportunities for biofunctionalization of individual nanowires.

Long Day's Journey into Night: Modernism, Post-Modernism and Maternal Loss

OpenAIRE

Meaney, Gerardine

2009-01-01

Long Day's journey into Night may seem a strange starting place for a feminist analysis of modernism and post-modernism. Yet even the most conservative criticism reads this play as an enactment and embodiment of loss, specifically loss of the mother. That loss is rarely seen in the context of a more general "loss", a cultural loss of legitimacy and authenticity, endemic in and enabling modernism, articulated as "disinheritance" by an Other "coded as feminine."

The "Journeys in Film" project brings important films and documentaries ("The Martian," "Hidden Figures," "River of Gold" and others) and curriculum-based, educational support activities to the classroom. Faculty from the University of New Hampshire, in partnership with selected local middle and high school teachers, developed a STEM Lesson Plan for Journeys in Film" focused on the soon-to-released documentary "River of Gold" which highlights tropical deforestation and illegal gold mining activities in the Peruvian jungles of the Amazon Basin. Using film clips (the Trailer) from the movie and the Lesson Plan, this approach allows pre-college students to learn how to use "Google Earth" to monitor chang-over-time and to quantify the areas of deforestation and mining using multi-date NOAA/USGS Landsat Thematic Mapper and ESA Copernicus satellite data. This approach will allow students to dconduct authentic hands-on science and mathematics to address a wide range of social and environmental issues associated with tropical deforestation in Peru.

Full Text Available This study explored how the Planning Alternatives Tomorrows with Hope (PATH process could enhance and strengthen an individual’s personal journey of recovery. This article utilised the knowledge base of members of a Community of Practice, located in Brisbane Australia. Members had a deep concern and passion to promote and strengthen wellbeing for people who live with the experience of mental ill health. They were invited to form a focus group to explore the use of PATH and its relationship with mental health wellness. After contemplating and reflecting on an example of the PATH process, the focus group explored opportunities for PATH to become one of many wellness resources for people experiencing and overcoming mental ill health. Through the exploration of personal meaning, storytelling and community connection (anchored in the visuals and graphics of the PATH example, the study found that PATH can make a valuable contribution by restoring some of the power inbalances in traditonal service frameworks and enhancing personal self direction.

The Pilgram's Progress: Reflections on the journey building Australia's solid earth information infrastructure (Invited)

Science.gov (United States)

Woodcock, R.

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.

Deep Space Gateway Science Opportunities

Quincy, C. D.; Charles, J. B.; Hamill, Doris; Sidney, S. C.

2018-01-01

The NASA Life Sciences Research Capabilities Team (LSRCT) has been discussing deep space research needs for the last two years. NASA's programs conducting life sciences studies - the Human Research Program, Space Biology, Astrobiology, and Planetary Protection - see the Deep Space Gateway (DSG) as affording enormous opportunities to investigate biological organisms in a unique environment that cannot be replicated in Earth-based laboratories or on Low Earth Orbit science platforms. These investigations may provide in many cases the definitive answers to risks associated with exploration and living outside Earth's protective magnetic field. Unlike Low Earth Orbit or terrestrial locations, the Gateway location will be subjected to the true deep space spectrum and influence of both galactic cosmic and solar particle radiation and thus presents an opportunity to investigate their long-term exposure effects. The question of how a community of biological organisms change over time within the harsh environment of space flight outside of the magnetic field protection can be investigated. The biological response to the absence of Earth's geomagnetic field can be studied for the first time. Will organisms change in new and unique ways under these new conditions? This may be specifically true on investigations of microbial communities. The Gateway provides a platform for microbiology experiments both inside, to improve understanding of interactions between microbes and human habitats, and outside, to improve understanding of microbe-hardware interactions exposed to the space environment.

Journey to become a nurse leader mentor: past, present and future influences.

Science.gov (United States)

McCloughen, Andrea; O'Brien, Louise; Jackson, Debra

2014-12-01

Mentorship, often viewed as a central capacity of leadership, is acknowledged as influential in growing nurse leaders. Mentoring relationships are perceived as empowering connections offering a dynamic guided experience to promote growth and development in personal and professional life. A hermeneutic phenomenological approach informed by Heidegger and Gadamer was used to explore understandings and experiences of mentorship for nurse leadership by 13 Australian nurse leaders. We found that learning and transformation associated with becoming a nurse leader mentor was experienced as an enduring evolutionary process. Participants' life journeys provided experiences that developed their understandings and established their personal identity as a leader and mentor. We considered the journey motif in terms of its inextricable connection with lived time and used Heidegger's ecstasies of temporality as a lens to understand how the temporal dimensions of past, present and future influenced and shaped the development of nurse leader mentors. We found that our temporal existence influences interpretation of ourselves and the world. Individuals can benefit from multiple separate mentoring interludes, with different mentors, over a lifetime. For some nurses, becoming a leader and mentor is a lifelong transformative process that grows from diverse experience and influential role modelling rather than formal instruction. © 2013 John Wiley & Sons Ltd.

A roadmap to peace. Journey metaphors in political speeches on the Middle East peace process

2014-07-01

Full Text Available Abstract – This paper investigates the metaphorical conceptualization of peace by former leaders George W. Bush, Ariel Sharon, and Mahmoud Abbas. Specifically, it examines how peace/the peace process is conceptualized via metaphors through the notion of JOURNEY and MOVEMENT. The corpus in this study comprises twenty speeches given by the three politicians over a four-year period (2002-2005. The corpus data is analyzed using a combination of different methods. The tools are mainly Conceptual Metaphor Theory (Lakoff and Johnson 1980, the MIPVU procedure (Steen et al. 2010, and Critical Metaphor Analysis (Charteris-Black 2004. Findings reveal that JOURNEY metaphors are a vital and common part of the three politicians’ political discourse. Overall, there are very few metaphors for peace unique to the individual politicians. The main differences observed lie not in which metaphors are used, but in what aspects of peace or the peace process they are used to highlight.Keywords: metaphor identification, conceptual metaphor, Critical Metaphor Analysis, political discourse, peace.

Wu, Wan-Ru; Chung, Ue-Lin; Chang, Sophia C N

2007-06-01

The purpose of this qualitative research study was to explore the preoperative through postoperative phase experience of women who had undergone augmentation mammaplasty. Nine women undergoing augmentation mammaplasty were selected by purposive sampling and interviewed using semi- structured, open-ended interview guidelines. Researchers used Symbolic interactionism to frame their overall perspective and analyzed data with the content analysis method. Rigors of data analysis were adopted credibility, transferability, dependability and confirmability proposed by Guba and Lincoln. The main theme of living experience of women who received augmentation mammaplasty could be summarized as "a journey to restore self-confidence". The categories identified within this journey included: (1) the invisible standards of breast beauty; (2) Taking courageous action to make changes; (3) conflicts between the natural and artificial. The above findings provided initial qualitative data from Taiwanese women's perspective. By better understanding their experience, nurses can become increasingly sensitive to patients' psychosocial adjustment and provide prudential nursing care.

Using measures to guide the continuous improvement journey: a partnership between quality assurance and toxicology.

Science.gov (United States)

Gentry, P E; Sites, D L

1994-03-01

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.

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

Science.gov (United States)

Prasad, Amit

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. © The Author(s) 2014.

Three Women’s Educational Doctoral Program Experiences: A Case Study of Performances and Journeys

Full Text Available Three academic women joined to write this piece to explore individual doctoral program experiences and to establish common understandings. They collectively analyzed their experiences using the conceptual approach of doctoral program performances and journeys. This case study shares their experiences within the conceptual approach through emerging themes. The common understandings developed herein about doctoral education based on these themes are also shared. The broader contributions of the three women’s work are two-fold. First, the entire case study provides a way to view, discuss, and consider women’s doctoral education pluralistically. Secondly, perhaps readers of this piece will recognize that individual and common understandings with others are a way to develop professional knowledge as academics. Further, readers of this piece might be able to relate more deeply to their own and others’ unique doctoral program experiences through the lens of performances or journeys. Some of these connections might be based on the overarching framework, while others might be specific to the shared women’s experiences.

Downey, Margaret Mary; Arteaga, Stephanie; Villaseñor, Elodia; Gomez, Anu Manchikanti

Contraceptive use is widely recognized as a means of reducing adverse health-related outcomes. However, dominant paradigms of contraceptive counseling may rely on a narrow definition of "evidence" (i.e., scientifically accurate but exclusive of individual women's experiences). Given increased enthusiasm for long-acting, reversible contraceptive methods, such paradigms may reinforce counseling that overprivileges effectiveness, particularly for groups considered at high risk of unintended pregnancy. This study investigates where and how women's experiences fit into the definition of evidence these counseling protocols use. Using a qualitative approach, this analysis draws on semistructured interviews with 38 young (ages 18-24) Black and Latina women. We use a qualitative content analysis approach, with coding categories derived directly from the textual data. Our analysis suggests that contraceptive decision making is an iterative, relational, reflective journey. Throughout contraceptive histories, participants described experiences evolving to create a foundation from which decision-making power was drawn. The same contraceptive-related decisions were revisited repeatedly, with knowledge accrued along the way. The cumulative experience of using, assigning meanings to, and developing values around contraception meant that young women experienced contraceptive decision making as a dynamic process. This journey creates a rich body of evidence that informs contraceptive decision making. To provide appropriate, acceptable, patient-centered family planning care, providers must engage with evidence grounded in women's expertise on their contraceptive use in addition to medically accurate data on method effectiveness, side effects, and contraindications.

Rape: the journey from victim to survivor: a critical literature survey

OpenAIRE

2008-01-01

M.A. The prevalence of rape in the world and particularly in South Africa, calls for the understanding of the factors involved in rape. In particular, it is necessary to understand rape in terms of the victim, not just in terms of the prevalence, causes and social consequences of rape. The victim’s experience of rape is complicated and takes place over a journey that progresses from the assault, through her responses and psychological and social reactions to her recovery from the trauma.

A GLOBAL MAGNETIC TOPOLOGY MODEL FOR MAGNETIC CLOUDS. II

Energy Technology Data Exchange (ETDEWEB)

Hidalgo, M. A., E-mail: miguel.hidalgo@uah.es [Departamento de Fisica, Universidad de Alcala, Apartado 20, E-28871 Alcala de Henares, Madrid (Spain)

2013-04-01

In the present work, we extensively used our analytical approach to the global magnetic field topology of magnetic clouds (MCs), introduced in a previous paper, in order to show its potential and to study its physical consistency. The model assumes toroidal topology with a non-uniform (variable maximum radius) cross-section along them. Moreover, it has a non-force-free character and also includes the expansion of its cross-section. As is shown, the model allows us, first, to analyze MC magnetic structures-determining their physical parameters-with a variety of magnetic field shapes, and second, to reconstruct their relative orientation in the interplanetary medium from the observations obtained by several spacecraft. Therefore, multipoint spacecraft observations give the opportunity to infer the structure of this large-scale magnetic flux rope structure in the solar wind. For these tasks, we use data from Helios (A and B), STEREO (A and B), and Advanced Composition Explorer. We show that the proposed analytical model can explain quite well the topology of several MCs in the interplanetary medium and is a good starting point for understanding the physical mechanisms under these phenomena.

Downhole Applications of Magnetic Sensors

2017-10-01

Full Text Available In this paper we present a review of the application of two types of magnetic sensors—fluxgate magnetometers and nuclear magnetic resonance (NMR sensors—in the oil/gas industry. These magnetic sensors play a critical role in drilling wells safely, accurately and efficiently into a target reservoir zone by providing directional data of the well and acquiring information about the surrounding geological formations. Research into magnetic sensors for oil/gas drilling has not been explored by researchers to the same extent as other applications, such as biomedical, magnetic storage and automotive/aerospace applications. Therefore, this paper aims to serve as an opportunity for researchers to truly understand how magnetic sensors can be used in a downhole environment and to provide fertile ground for research and development in this area. A look ahead, discussing other magnetic sensor technologies that can potentially be used in the oil/gas industry is presented, and what is still needed in order deploy them in the field is also addressed.

A Journey to Wholeness Through Tai Chi

Science.gov (United States)

Al-Turki, Faiza

Healing is a multifaceted venture. Whereas many traditional cultures see healing as a journey that, by necessity, combines body, mind, and spirit, today's Western society frequently divides healing, relegating its parts to various experts--body to physicians, mind to psychologists, spirit to religions. Employing heuristic and alchemical hermeneutic methodologies, this thesis explores tai chi as a healing tool that bridges that division, exploring the following question: is it possible that the connection of body, mind, and spirit offered by tai chi is the very mechanism by which it facilitates healing? The cultural and historical context of tai chi is introduced, as well as research showing various Western views. A heuristic approach offers personal examples of the use of tai chi as a process partner, while a depth psychological lens informs the use of tai chi principles to guide moments of self-exploration and transformation in a therapeutic way.

Sorrell, Jeanne M; Cangelosi, Pamela R; Dinkins, Christine S

2014-03-01

There is little information in the literature describing how students learn qualitative research. This article describes an approach to learning that is based on the pedagogical approach of Dinkins' Socratic-Hermeneutic Shared Inquiry. This approach integrates shared dialog as an essential aspect of learning. The qualitative pedagogy described in this article focused on three questions: What is knowing in qualitative research? How do we come to know qualitative research? What can we do with qualitative research? Students learned the basics of qualitative research within a context that fostered interpretive inquiry. In this way, the course framework mirrored the combination of interviewing, storytelling, and journeying toward understanding that constitute qualitative research. © 2013.

Full Text Available Anastasia’s Journeys was a temporary exhibition in the Australian History Museum, Macquarie University, Australia. Developed from the oral history of a post-World War Two Russian immigrant who survived Stalin’s policies of forced collectivisation and engineered famine, the display communicated primarily through audio tracks, supported by text panels and objects. This article articulates the creative tensions between theory and practice of public history which were encountered when planning the target audience, content, and design of the exhibition. It describes the process by which the oral history was placed at the centre of the presentation while objects were used both to illustrate changing social situations and introduce an opposing interpretation. The attributes of the oral history which made it suitable for an audio presentation are then discussed.

The Westinghouse Magnet Systems Division (WMSD) was formed in late 1990 when the Superconducting Super Collider Laboratory (SSCL) awarded WMSD the Follower portion of the contract for manufacturing collider dipole magnets. The Division's small cadre of management start-up personnel moved into its office and manufacturing facility in Round Rock, Texas in August of 1991. In January 1992, WMSD won a second SSCL contract to design and build the High Energy Booster dipole magnets. These contracts presented a rare opportunity: the chance to start with a clean slate and to build, from the bottom up, a whole new product, with all its required manufacturing processes and all its management systems. This was the opportunity to open-quotes do it right the first time.close quotes With these two contracts, doing it right the first time is the only way that WMSD can succeed. By mid-1994, WMSD will start its delivery of collider dipole magnets for installation in the Super Collider tunnel. Each of the magnets, from the first delivery through the last, requires a calculated reliability of 99.99954 percent. This is six sigma performance the first time with little or no opportunity for trial and error, false starts, and continuous improvement. In late 1994, the SSCL will award the full production contract for collider dipole magnets to one of the two preproduction (or a combination of both) subcontractors, based on performance during the preproduction and low rate initial production phases. There will be no second chance in the quality, reliability, delivery and cost competition for this contract. This paper describes the Westinghouse's quality assurance program. This program has twelve conditions of excellance: customer orientation, participation, development, motivation, products and services, process and procedures, information, suppliers, culture, planning, communications, and accountability

The academic journey of university students on Facebook: an analysis of informal academic-related activity over a semester

Directory of Open Access Journals (Sweden)

Rebecca Vivian

2014-08-01

Full Text Available This paper reports on an observation of 70 university students’ use of their personal social network site (SNS, Facebook, over a 22-week university study period. The study sought to determine the extent that university students use their personal SNSs to support learning by exploring frequencies of academic-related content and topics being discussed. The findings reported in the paper reveal that students used their personal SNSs to discuss academic-related topics, particularly to share experiences about doing work or procrastinating, course content and grades. Mapping academic-related activity frequencies over the 22 weeks illustrated that around certain points in the academic calendar, particularly times when students’ assignments or exams were nearing, academic activity increased, suggesting that SNSs may play an important role in a students’ academic experience.The findings suggest that many students today may be leaving traces of their academic journey online and that academics should be aware that these interactions may also exist in their own students’ online social spaces. This study offers opportunities for future research, particularly research which seeks to determine differences between individuals' academic activity, the extent that intensive SNSs use supports or distracts students from learning, as well as the extent to which universities should or can harness SNSs to improve the student experience.

Schweickardt, Júlio César; Lima, Nísia Trindade

2007-12-01

The article analyzes reports from two scientific journeys into the Amazon conducted by the Instituto Oswaldo Cruz, in 1910 and 1913, under the leadership of Oswaldo Cruz and Carlos Chagas, respectively. These reports contributed to the construction of representations and images of the region. Field observations not only provided data for the study and control of tropical diseases but also had a hand in the movement to denounce the serious sanitation conditions under which rubber workers labored. Journeys through the Amazon valley put the scientists in direct contact with the environment and with sick populations; these travels also made them face the huge challenges of learning about malaria and trying to control it. Analyses of these reports are part of studies on 'portraits of Brazil', which raise issues within the history of public health policies. In this endeavor to reveal the process by which scientific records are constructed, we worked with primary sources,from manuscripts to official texts.

Lacanian Orders in Eugene O’Neill’s Long Day’s Journey into Night

Directory of Open Access Journals (Sweden)

Sima Farshid

2013-03-01

Full Text Available This paper presents a Lacanian reading of Eugene O’Neill’s Long Day’s Journey into Night (1941 by drawing on the psychic orders the well-known French psychoanalyst Jacques Lacan has propounded. He holds that human psyche is formed of three orders (the Imaginary, the Symbolic and the Real which mold the unconscious mind and motivate human actions and reactions. He also argues that the Other has an immense impact on the formation of psychic orders, especially the Symbolic, and hence on one’s identity. The present article attempts to investigate the three orders of the characters O’Neill has portrayed in Long Day’s Journey into Night, besides the role of the Other in the formation of those orders. The reactions of these characters to the outside world are regarded here as the outer presentation of their troubled mind. It is also discussed that the mental and physical problems and disorders of these characters, such as their addiction to alcohol and drugs, are the outcome of their repressed desires which have remained unfulfilled because of the rules defined and imposed on them by the Other – hence the frustrating sense of lack observed in all four characters.

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

Science.gov (United States)

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.

Magnetic separations: From steel plants to biotechnology

Energy Technology Data Exchange (ETDEWEB)

Cafer T. Yavuz; Arjun Prakash; J.T. Mayo; Vicki L. Colvin [Rice University, Houston, TX (United States). Department of Chemistry

2009-05-15

Magnetic separations have for decades been essential processes in diverse industries ranging from steel production to coal desulfurization. In such settings magnetic fields are used in continuous flow processes as filters to remove magnetic impurities. High gradient magnetic separation (HGMS) has found even broader use in wastewater treatment and food processing. Batch scale magnetic separations are also relevant in industry, particularly biotechnology where fixed magnetic separators are used to purify complex mixtures for protein isolation, cell separation, drug delivery, and biocatalysis. In this review, we introduce the basic concepts behind magnetic separations and summarize a few examples of its large scale application. HGMS systems and batch systems for magnetic separations have been developed largely in parallel by different communities. However, in this work we compare and contrast each approach so that investigators can approach both key areas. Finally, we discuss how new advances in magnetic materials, particularly on the nanoscale, as well as magnetic filter design offer new opportunities for industries that have challenging separation problems.

Affirmation through disability: one athlete's personal journey to the London Paralympic Games.

Science.gov (United States)

Kavanagh, Emma

2012-03-01

This article explores the personal narrative of a British Paralympic wheelchair tennis player who experienced a spinal cord injury (SCI) following a motorcycle accident in 2001 that left her paralysed from the waist down. The study responds to the call by Swain and French, among others, for alternative accounts of disability that demonstrate how life following impairment need not be empty and meaningless, but can actually reflect a positive, if different, social identity. This study draws upon life history data to investigate the journey of one athlete who has managed to achieve international sporting success following a life-changing accident. A pseudonym has not been used for this study as the athlete wanted to be named in the research account and for her story to be shared. A chronological approach was adopted to map the pre- and post-accident recovery process. The account examines life before the trauma, the impact of the accident, the process of rehabilitation and the journey to athletic accomplishment. Negative views of disability can be challenged if disability is viewed in the context of positive life narratives. The story of one Paralympian demonstrates how an 'ordinary' person has made the most of an extraordinary situation and become a world-class athlete. This paper demonstrates that in contrast to typical discourse in disability studies, becoming disabled or living with a disability need not be a tragedy but may on the contrary enhance life and lead to positive affirmation.

Leadership as a Personal Journey: An Indigenous Perspective.

Science.gov (United States)

Doyle, Kerrie; Hungerford, Catherine

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.

Microstructure and magnetic properties of inert gas atomized rare earth permanent magnetic materials

International Nuclear Information System (INIS)

Sellers, C.H.; Hyde, T.A.; Branagan, D.J.; Lewis, L.H.; Panchanathan, V.

1997-01-01

Several permanent magnet alloys based on the ternary Nd 2 Fe 14 B (2-14-1) composition have been prepared by inert gas atomization (IGA). The microstructure and magnetic properties of these alloys have been studied as a function of particle size, both before and after heat treatment. Different particle sizes have characteristic properties due to the differences in cooling rate experienced during solidification from the melt. These properties are also strongly dependent on the alloy composition due to the cooling rate close-quote s effect on the development of the phase structure; the use of rare earth rich compositions appears necessary to compensate for a generally inadequate cooling rate. After atomization, a brief heat treatment is necessary for the development of the optimal microstructure and magnetic properties, as seen from the hysteresis loop shape and improvements in key magnetic parameters (intrinsic coercivity H ci , remanence B r , and maximum energy product BH max ).

Experience with the SLC permanent magnet multipoles

International Nuclear Information System (INIS)

Gross, G.; Spencer, J.

1994-06-01

Permanent magnets have been used in the SLC Damping Rings and their injection and extraction lines since 1985. Recent upgrades of the DR vacuum chambers provided an opportunity to check DR magnets prior to higher beam current operation. Several PM sextupoles downstream of the injection kickers in the electron ring had exceeded their thermal stabilization values of 80 degrees C and some showed serious mechanical deformations and radiation >1 R at contact. We discuss our observations, measurements and a few inexpensive modifications that should improve these magnets under such conditions. A new, block matching algorithm allowed us to use magnet blocks that had been considered unusable because of very different remament field strengths and easy axis errors

A journey towards inclusive education; a case study from a 'township' in South Africa.

Luger, Rosemary; Prudhomme, Debbie; Bullen, Ann; Pitt, Catherine; Geiger, Martha

2012-01-01

The purpose of this case study was to relate part of the journey to appropriate education for two young children with physical disabilities in a low socio-economic peri-urban informal settlement - or 'township' - in South Africa. The part of the on-going journey described here spanned four-and-a-half years and included the two children, their families, their teachers, their community and a small team of rehabilitation professionals working for a non-profit organisation in the area. The rehabilitation professionals' goals were to provide support for the children, their families, their current special care centre and the school(s) they would attend in the future. The steps from the special care centre, to a mainstream early childhood development (ECD) centre for both of them, and then on to (a) a school for learners with special educational needs (LSEN) for one child and (b) a mainstream primary school for the other, are described. Challenges encountered on the way included parental fears, community attitudes and physical accessibility. Practical outcomes included different placements for the two children with implications and recommendations for prioritised parent involvement, individual approaches, interdisciplinary and community-based collaborations. Recommendations are given for clinical contexts, curricula and policy matters; for research and for scaling up such a programme through community workers.

Quark contributions to baryon magnetic moments in full, quenched, and partially quenched QCD

International Nuclear Information System (INIS)

Leinweber, Derek B.

2004-01-01

The chiral nonanalytic behavior of quark-flavor contributions to the magnetic moments of octet baryons is determined in full, quenched and partially quenched QCD, using an intuitive and efficient diagrammatic formulation of quenched and partially quenched chiral perturbation theory. The technique provides a separation of quark-sector magnetic-moment contributions into direct sea-quark loop, valence-quark, indirect sea-quark loop and quenched valence contributions, the latter being the conventional view of the quenched approximation. Both meson and baryon mass violations of SU(3)-flavor symmetry are accounted for. Following a comprehensive examination of the individual quark-sector contributions to octet baryon magnetic moments, numerous opportunities to observe and test the underlying structure of baryons and the nature of chiral nonanalytic behavior in QCD and its quenched variants are discussed. In particular, the valence u-quark contribution to the proton magnetic moment provides the optimal opportunity to directly view nonanalytic behavior associated with the meson cloud of full QCD and the quenched meson cloud of quenched QCD. The u quark in Σ + provides the best opportunity to display the artifacts of the quenched approximation

True navigation and magnetic maps in spiny lobsters.

Science.gov (United States)

Boles, Larry C; Lohmann, Kenneth J

2003-01-02

Animals are capable of true navigation if, after displacement to a location where they have never been, they can determine their position relative to a goal without relying on familiar surroundings, cues that emanate from the destination, or information collected during the outward journey. So far, only a few animals, all vertebrates, have been shown to possess true navigation. Those few invertebrates that have been carefully studied return to target areas using path integration, landmark recognition, compass orientation and other mechanisms that cannot compensate for displacements into unfamiliar territory. Here we report, however, that the spiny lobster Panulirus argus oriented reliably towards a capture site when displaced 12-37 km to unfamiliar locations, even when deprived of all known orientation cues en route. Little is known about how lobsters and other animals determine position during true navigation. To test the hypothesis that lobsters derive positional information from the Earth's magnetic field, lobsters were exposed to fields replicating those that exist at specific locations in their environment. Lobsters tested in a field north of the capture site oriented themselves southwards, whereas those tested in a field south of the capture site oriented themselves northwards. These results imply that true navigation in spiny lobsters, and perhaps in other animals, is based on a magnetic map sense.

Gotsis, Harry; Kioussis, Nicholas; Papaconstantopoulos, Dimitri

2004-03-01

Advances in low-temperature scanning tunneling microscopy under ultrahigh vacuum have provided new opportunities for investigating the magnetic structures of nanoclusters adsorbed on surfaces. Recent STM studies of Cr trimers on the Au(111) surface suggest a switching between two distinct electronic states. We have carried out ab initio electronic structure calculations to investigate the structural, electronic and magnetic properties of isolated Cr atoms, Cr dimers and trimers in different geometry. We will present results for the evolution of magnetic behavior including noncollinear magnetism and provide insight in the connection between magnetism and geometry.

Talijan Nadežda M.

2006-01-01

Full Text Available Magnetic properties of permanent magnetic materials based on intermetallic compounds of Sm-Co and Nd-Fe-B are in direct dependence on the microstructure. In the first part of this paper, having in mind the importance of the regime of sintering and heat treatment to obtain the optimal magnetic structure, yet another approach in defining the most adequate technological parameters of the sintering process for applied heat treatment conditions was made. The goal of these investigations was to use the correlation that exists between sintering conditions (temperature and time and intensity of the diffraction peak of the (111 plane of the SmCo5 phase to optimize. In the second part a brief overview of high energy magnetic materials based on Nd-Fe-B is presented with special emphasis to the current research and development of high remanent nanocomposite magnetic materials based on Nd-Fe-B alloys with a reduced Nd content. Part of experimental results gained during research of the sintering process of SmCo5 magnetic materials were realized and published earlier. The scientific meeting devoted to the 60th anniversary of Frankel’s theory of sintering was an opportunity to show once more the importance and role of sintering in optimization of the magnetic microstructure of sintered Sm Co5 magnetic materials.

2013-12-01

Full Text Available This paper focuses on some textual and discursive aspects of the Guimarães Rosa´s story “A hora e vez de Augusto Matraga”, concerning to description sequences and its role in the configuration of the fictional space. We discuss a narrative matrix whose spatial and temporal structures reveal a trajectory towards the human being redemption – a kind of initiation journey, marked by the mystic of an ascetic life. The analyses also points to the recurrent themes of violence and religiousness that support the narrative tension, straightly related to the protagonist conflicts. Violence and religiousness express the initiation journey paradoxes. Our methodology adopts theoretical contributions of the Pragmatic Linguistics and the Textual Analysis of the Discourses.

A Short Journey from Quarks to the Universe

CERN Document Server

Economou, Eleftherios N

2011-01-01

This book takes the reader for a short journey over the structures of matter showing that their main properties can be obtained even at a quantitative level with a minimum background knowledge. The latter, besides some high school physics and mathematics, consists of the three cornerstones of science presented in chapters 1 to 3, namely the atomic idea, the wave-particle duality, and the minimization of energy as the condition for equilibrium. Dimensional analysis employing the universal constants and combined with “a little imagination and thinking”, to quote Feynman, allows an amazing short-cut derivation of several quantitative results concerning the structures of matter. This book is expected to be of interest to physics, engineering, and other science students and to researchers in physics, material science, chemistry, and engineering who may find stimulating the alternative derivation of several real world results, which sometimes seem to pop out the magician’s hat.

Transcultural spirituality: the spiritual journey of hospitalized patients with schizophrenia in Taiwan.

Science.gov (United States)

Yang, Chun-Tien; Narayanasamy, Aru; Chang, Sung-Ling

2012-02-01

The aim of this study was to explore how hospitalization and the diagnosis of schizophrenia have an impact on Taiwanese patients' spiritual life. Psychiatric nurses tend to construe patients' spiritual issues as pathological problems and consequently are reluctant to address patient's spirituality, which results in spirituality being overlooked in mental illness. An individual's spiritual journey is dependent upon their cultural background and beliefs; however, the professional's preconceived ideas suppress the voice of patients with schizophrenia to share their experiences of their spiritual journey. The lack of research exploring spirituality in mental illness in Taiwan means that spiritual care is overlooked in practice. This study sets out to explore spirituality from the perspectives of patients in two mental hospitals in Taiwan. Using a qualitative approach, 22 long-term hospitalized patients diagnosed with schizophrenia were interviewed. Several themes from the data were identified using Ritchie and Spencer's (1994) five stages analytical framework. The study was carried out from 2006 to 2008. Patients revealed spiritual distress as a consequence of prolonged hospitalization. They used referents consistent with traditional Chinese philosophical perspectives derived from Taoism and Confucianism to describe various features of their spiritual distress and their longing for spiritual revival, transcendence and to be accepted as normal persons. In this age of globalization, nurses need to be fully cognisant of the cultural aspects of patients to respond to a mental health patient's spirituality. Clinical and educational guidelines and policies could be developed for spiritual care in Taiwan. © 2011 The Authors. Journal of Advanced Nursing © 2011 Blackwell Publishing Ltd.

The identification of possible future provincial boundaries for South Africa based on an intramax analysis of journey-to-work data

Directory of Open Access Journals (Sweden)

JH Nel

2008-12-01

Full Text Available National census data contain information on place of residence and place of work. It is possible to combine this information~and create journey-to-work flows. The process of establishing these flows are presented in this paper. The intramax method is explained and used to identify functional regions based upon these flows. Interesting applications, such as the demarcation of regions in South Africa are considered and solutions to disputed areas are put forward. The process of the creation of the current provincial boundaries are discussed. New boundaries, based on the intramax analysis of the journey-to-work data are proposed for four or five new provinces. Results compare favourably with those from a principal component and cluster analysis, which has previously been used to demarcate the South African space economy into a hierarchy of development regions.

Magnetic Phase Diagram of α-RuCl3

Science.gov (United States)

Sears, Jennifer; Kim, Young-June; Zhao, Yang; Lynn, Jeffrey

The layered honeycomb material α-RuCl3 is thought to possess unusual magnetic interactions including a strong bond-dependent Kitaev term, offering a potential opportunity to study a material near a well understood spin liquid phase. Although this material orders magnetically at low temperatures and is thus not a realization of a Kitaev spin liquid, it does show a broad continuum of magnetic excitations reminiscent of that expected for the spin liquid phase. It has also been proposed that a magnetic field could destabilize the magnetic order in this material and induce a transition into a spin liquid phase. Low temperature magnetization and specific heat measurements in this material have suggested a complex magnetic phase diagram with multiple unidentified magnetic phases present at low temperature. This has provided motivation for our work characterizing the magnetic transitions and phase diagram in α-RuCl3. I will present detailed bulk measurements combined with magnetic neutron diffraction measurements to map out the phase diagram and identify the various phases present.

Dealing with colon cancer: one woman's emotional journey.

Wilson, Candice T; Fletcher, Paula C

2002-11-01

Although death is inevitable, it continues to remain a taboo issue for society. A failure to discuss the unavoidable may represent a safeguard to avoid dealing with mortality and related fears. Many patients who are terminally ill spend their days feeling alone, misunderstood, and afraid. Kubler-Ross attempted to strip death of its negative connotations and to provide a venue for the terminally ill to have a voice. Using information from more than 200 clinical interviews, Kubler-Ross revealed a trend in emotions over time in most, but not all, of her patients, which enabled her to formulate a model of coping with death that included 5 interdependent emotional stages: denial, anger, bargaining, depression, and acceptance. This model has become the most widely accepted and popularized model on death and dying, often cited as the Five Stages of Grief." However, given the lack of research concerning Kubler-Ross's model, completing work in this area seems warranted. The purpose of this case study was to examine one individual's emotional journey after being diagnosed with terminal colon cancer. More specifically, the goals were twofold: (1) to provide the participant with a voice and to allow her story to be told by examining the major external events (ie,surgery, chemotherapy) occurring since the diagnosis that affected her emotional and physical well-being and (2) to determine whether the participant's emotional journey paralleled Kubler-Ross's model, to what extent, and whether new emotions or stages occurred. The participant, a 50-year-old female, was diagnosed with stage 4 Duke Stage D colon cancer. Qualitative information was collected in face-to-face interviews, newspaper articles about the participant, and e-mail correspondence (as form letters to a group of friends and supporters) and subsequently analyzed for trends. The overall results revealed clear existence of the 5 stages of grief as outlined in the Kubler-Ross model. Analyses also revealed that the

Selective Induction of Optical Magnetism.

2017-12-13

An extension of the Maxwell-Faraday law of electromagnetic induction to optical frequencies requires spatially appropriate materials and optical beams to create resonances and excitations with curl. Here we employ cylindrical vector beams with azimuthal polarization to create electric fields that selectively drive magnetic responses in dielectric core-metal nanoparticle "satellite" nanostructures. These optical frequency magnetic resonances are induced in materials that do not possess spin or orbital angular momentum. Multipole expansion analysis of the scattered fields obtained from electrodynamics simulations show that the excitation with azimuthally polarized beams selectively enhances magnetic vs electric dipole resonances by nearly 100-fold in experiments. Multipolar resonances (e.g., quadrupole and octupole) are enhanced 5-fold by focused azimuthally versus linearly polarized beams. We also selectively excite electric multipolar resonances in the same identical nanostructures with radially polarized light. This work opens new opportunities for spectroscopic investigation and control of "dark modes", Fano resonances, and magnetic modes in nanomaterials and engineered metamaterials.

Journeys to Others and Lessons of Self: Carlos Castaneda in Camposcape

Directory of Open Access Journals (Sweden)

Ageeth Sluis

2012-12-01

Full Text Available Drawing on Michel Foucault’s concept of heterotopia, this article examines the importance of place and gender within constructions of race politics in Carlos Castaneda’s series on shamanism. Championing a “separate reality” predicated on an indigenous worldview, Castaneda’s lessons invited transnational middle-class youth to "journey" alongside him to camposcape—an anachronistic and idealized countryside—as a means to escape the bourgeois values of their homelands and find spiritual fulfillment in a timeless and "authentic" Mexico. Castaneda’s work proposed new viable spaces of difference in Mexico, yet inscribed these spaces with a masculinist discourse that served to neutralize the gender trouble within the counterculture movement in both Mexico and the US.

The botanical legacy of Thomas Hardwicke’s journey to Srinagar in 1796

Directory of Open Access Journals (Sweden)

2015-01-01

Full Text Available In 1796, Thomas Hardwicke travelled through northern India between what is now Fatehgarh in Uttar Pradesh and Srinagar in Uttarakhand. Hardwicke collected and described plants encountered and had many of the plants illustrated from life. He published an account of the journey in 1799 including a list of plant species. I review the names validated in the original paper, and also those published subsequently by Sir James Edward Smith and William Roxburgh based partly or wholly on the material or drawings acquired by Hardwicke on the journey to Srinagar. The large collection of Hardwicke plant drawings now held in the British Library, and a smaller set in the Botany Library of the Natural History Museum, are considered in relation to the application and typification of plant names related to Hardwicke’s botanical exploration in India. The names of seven plant species were validly published in the 1799 paper (Androsace rotundifolia Hardw., Ficus laminosa Hardw., Justicia thyrsiformis Roxb. ex Hardw., Linum trigynum Roxb. ex Hardw., Lonicera quinquelocularis Hardw., Salvia integrifolia Roxb. ex Hardw. and Volkameria bicolor Hardw., plus one new combination (Echites antidysentericus (L. Roxb. ex Hardw.. As concluded by Britten more than a century ago, Ficus laminosa is the correct name for the fig variously referred to F. saemocarpa Miq. or F. squamosa Roxb. Smith based Rhododendron arboreum Sm. and Bignonia undulata Sm. on Hardwicke plants. At least a dozen Roxburgh names, including Crataegus integrifolia Roxb., Gardenia tetrasperma Roxb. and Morus serrata Roxb., are based, at least partly, on Hardwicke’s collections. In total, 23 names are lectotypified here and one neotype is designated.

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

Science.gov (United States)

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.

Journey of a molecular biologist.

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.

2014-06-01

Internationally, there is growing interest in the applicability of visual management in healthcare, although little is known about the extent of its effectiveness. In the past 5 years technical advances have permitted the integration of all relevant data into a singular display that can improve staff efficiency, accelerate decisions, streamline workflow processes and reduce oversights and errors in clinical practice. The aim of the case study is to describe the features and application of electronic patient journey boards (EPJBs) as an enabler to accelerate patient flow that has been demonstrated and evaluated in Queensland Health hospitals. In 2012 and 2013 we collected ward-specific data that was sourced from the Queensland Hospital Admitted Patient Data Collection, determining the top 10 overnight diagnostic-related groups (DRGs) for each ward participating in the pilots. The Statistical Output Unit within Queensland Health then provided data and analysis on the ALOS for each of these DRGs for the period following an EPJB installation, along with the ALOS for the same DRGs for the corresponding period in the previous year. Patient length of stay reduced and display of estimated discharge dates improved with the introduction of EPJBs along with improved communication and information management resulting in time savings from 20 min per staff member per shift to 2.5h per ward a day. Queensland and South Australian Health systems have succeeded in 'making the hospital patient journey visible' through an innovative combination of information management and prominent display of key information related to patient care portrayed on large liquid crystal display (LCD) screens in hospital wards.

On 29 May, CNGS (CERN Neutrinos to Gran Sasso) will send the first neutrino beams from CERN to the Gran Sasso Laboratory in Italy. The neutrinos will journey 730 km through the earth's crust. To mark the occasion, Discovery Mondays is organising a special evening devoted to the CNGS project, whose purpose is to provide us with a better understanding of the neutrino, a particle that is still shrouded in mystery. The neutrino is an elusive particle that is very difficult to study. Masters of the art of evading capture, neutrinos can pass through thousands of kilometres of matter with little or no interaction. As you are reading this text, 400000 billion neutrinos from the sun are passing through your body every second. However, only one or two will be stopped by your body during your entire lifetime. Detecting neutrinos is therefore a very arduous task. This is why we still know so little about them. At the next Discovery ...

The current global refugee crisis involves 65.3 million persons who have been displaced from their homes or countries of origin. While escaping immediate harm may be their first priority, displaced people go on to face numerous health risks, including trauma and injuries, malnutrition, infectious diseases, exacerbation of existing chronic diseases, and mental health conditions. This crisis highlights the importance of building capacity among health-care providers, scientists, and laboratorians to understand and respond to the health needs of refugees. The November 2016 American Society of Tropical Medicine and Hygiene (ASTMH) conference in Atlanta will feature an interactive exhibit entitled "The Refugee Journey to Wellbeing" and three symposia about refugee health. The symposia will focus on tropical disease challenges in refugee populations, careers in refugee health, and recent experiences of governmental agencies and nongovernmental organizations in responding to the global refugee crisis. We invite ASTMH attendees to attend the exhibit and symposia and consider contributions they could make to improve refugee health through tropical disease research or clinical endeavors. © The American Society of Tropical Medicine and Hygiene.

Materials for room temperature magnetic refrigeration

Energy Technology Data Exchange (ETDEWEB)

Rosendahl Hansen, B.

2010-07-15

Magnetic refrigeration is a cooling method, which holds the promise of being cleaner and more efficient than conventional vapor-compression cooling. Much research has been done during the last two decades on various magnetic materials for this purpose and today a number of materials are considered candidates as they fulfill many of the requirements for a magnetic refrigerant. However, no one material stands out and the field is still active with improving the known materials and in the search for a better one. Magnetic cooling is based on the magnetocaloric effect, which causes a magnetic material to change its temperature when a magnetic field is applied or removed. For room temperature cooling, one utilizes that the magnetocaloric effect peaks near magnetic phase transitions and so the materials of interest all have a critical temperature within the range of 250 - 310 K. A magnetic refrigerant should fulfill a number of criteria, among these a large magnetic entropy change, a large adiabatic temperature change, preferably little to no thermal or magnetic hysteresis and the material should have the stability required for long term use. As the temperature range required for room temperature cooling is some 40 - 50 K, the magnetic refrigerant should also be able to cover this temperature span either by exhibiting a very broad peak in magnetocaloric effect or by providing the opportunity for creating a materials series with varying transition temperatures.

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.

Nonlinear effects at the nanoscale are usually associated with the enhancement of electric fields in plasmonic structures. Recently emerged new platform for nanophotonics based on high-index dielectric nanoparticles utilizes optically induced magnetic response via multipolar Mie resonances and provides novel opportunities for nanoscale nonlinear optics. Here, we observe strong second-harmonic generation from AlGaAs nanoantennas driven by both electric and magnetic resonances. We distinguish experimentally the contribution of electric and magnetic nonlinear response by analyzing the structure of polarization states of vector beams in the second-harmonic radiation. We control continuously the transition between electric and magnetic nonlinearities by tuning polarization of the optical pump. Our results provide a direct observation of nonlinear optical magnetism through selective excitation of multipolar nonlinear modes in nanoantennas.

Magnetic sorting using magnetic beads has become a routine methodology for the separation of key cell populations from biological suspensions. Due to the inherent ability of magnets to provide forces at a distance, magnetic cell manipulation is now a standardized process step in numerous processes in tissue engineering, medicine, and in fundamental biological research. Herein we review the current status of magnetic particles to enable isolation and separation of cells, with a strong focus on the fundamental governing physical phenomena, properties and syntheses of magnetic particles and on current applications of magnet-based cell separation in laboratory and clinical settings. We highlight the contribution of cell separation to biomedical research and medicine and detail modern cell separation methods (both magnetic and non-magnetic). In addition to a review of the current state-of-the-art in magnet-based cell sorting, we discuss current challenges and available opportunities for further research, development and commercialization of magnetic particle-based cell separation systems.

Full Text Available Nowadays the joint themes of living at the borderland of cultures and responding to the pressures which emerge during the necessary re-formation of identity are treated in an increasing number of literary works. The subject of the present paper is Anne Devlin’s After Easter, a drama which uses the trope of the journey to fuse the constraints of exilic existence with narratives of gender, race and generational tension. My analysis explores how Greta, questor of a new diasporic identity, manages to reinterpret conflicting images and discourses as she confronts them on revisiting her original home country, Troubles-ridden Northern Ireland. By the end of the journey she is able to invent her own story, intertwining concerns of origin and continuity, love of the mother(land as well as of the Other, and through that she re-constructs her identity as a self-assured migrant.

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

The emergence of complex behaviours in molecular magnetic materials.

Goss, Karin; Gatteschi, Dante; Bogani, Lapo

2014-09-14

Molecular magnetism is considered an area where magnetic phenomena that are usually difficult to demonstrate can emerge with particular clarity. Over the years, however, less understandable systems have appeared in the literature of molecular magnetic materials, in some cases showing features that hint at the spontaneous emergence of global structures out of local interactions. This ingredient is typical of a wider class of problems, called complex behaviours, where the theory of complexity is currently being developed. In this perspective we wish to focus our attention on these systems and the underlying problematic that they highlight. We particularly highlight the emergence of the signatures of complexity in several molecular magnetic systems, which may provide unexplored opportunities for physical and chemical investigations.

Tunisian Migrant Journeys: Human Rights Concerns for Tunisians Arriving by Sea

Directory of Open Access Journals (Sweden)

Maegan Hendow

2013-08-01

Full Text Available In part due to its location on the North African coast, in conjunction with its history of being a former French protectorate, Tunisia has become an important country of emigration to the European Union. In particular, maritime arrivals have become a concern for European states, for both humanitarian and security reasons. The experiences of Tunisian irregular migrants arriving to the EU by sea, who are then detained and returned, highlights the multitude of human rights issues that arise across their journey as they interact with the various stakeholders involved—Tunisian and Libyan smugglers, EU and Tunisian authorities and NGOs, amongst others. The situation for these migrants at sea and during rescue and interception operations can most directly involve such issues as the right to life, access to food and water, access to emergency healthcare and access to information. The next stages of detention and return (either immediately or when later identified on EU territory can most directly involve human rights issues related to the identification and referral mechanisms for groups at risk, access to information and legal remedy, the right of “non-refoulement” and prohibition of torture, inhuman and degrading treatment and punishment. By examining Tunisian migrant experiences along the entirety of their trajectory, one can see the specific human rights issues that arise at each stage for maritime arrivals—from departure to return. The article will examine these human rights concerns in the context of the Tunisian migrant journey, focusing on the four identified stages of the situation at sea, rescue or interception, detention and return. The article will present results from qualitative in-depth interviews conducted for the EU Fundamental Rights Agency in 2011 with 15 Tunisian migrants who had arrived by sea to Italy between 2005 and 2011 and were returned to Tunisia between 2008 and 2011, complemented by interviews with two Tunisian

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. Copyright © 2014 American Society for Pain Management Nursing. Published by Elsevier Inc.

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

Science.gov (United States)

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

Principle features of metal magnetic memory method and inspection tools as compared to known magnetic NDT methods

International Nuclear Information System (INIS)

Dubov, A.

2006-01-01

Principle features of method of metal magnetic memory (MMM) as compared to known magnetic NDT methods are considered. Among the basic features of the MMM method, that it is based on use of the own magnetic leakage field (SMLF), arising in ferromagnetic and paramagnetic products on accumulations of high-density dislocations. Magnetodislocation hysteresis underlying effect of metal magnetic memory, takes place as at manufacture of products during formation of internal stresses and at their operation under action of working loads. It is impossible to obtain an information source like a self-magnetic field at any conditions with artificial magnetization in working constructions. Such information is formed and can be obtained only in a small external field, as the Earth's magnetic field is, in loaded constructions when deformation energy is a cut above the energy of the external magnetic field. Features and uniqueness of magnetometric instruments are considered. The instruments have no world analogues. Opportunities of the MMM method for the solution of actual NDT problems are: 100% quality control of machine-building products and heterogeneity of metal structure in a line production; express quality control of welded joints in the united complex system of the factors 'structural-mechanical heterogeneity - defects of a weld - structural and technological stress concentrator'; and, early diagnostics of fatigue damages of metal at an estimation and forecasting of equipment lifetime.

Opportunistic maintenance considering non-homogenous opportunity arrivals and stochastic opportunity durations

International Nuclear Information System (INIS)

2017-01-01

Many systems and manufacturing processes undergo intermittent operation due to external factors (e.g. weather, low market prices), offering opportunities to conduct maintenance with reduced production losses. Making use of appropriate opportunities can thus lead to significant reduction in the total cost of maintenance and improvement in productivity. In this paper, an opportunistic maintenance (OM) model is developed considering two critical properties of real world opportunities: (i) non-homogeneous opportunity arrivals and (ii) stochastic opportunity duration. The model enables exploiting downtime cost savings from “partial” opportunities (stops shorter than the required maintenance time) thus extending the potential benefit of OM. The criteria for accepting maintenance opportunities are found by minimizing the single-cycle total cost. A closed form expression of the single-cycle total cost is derived for a given PM/OM policy and then a Genetic Algorithm is used to solve the optimization problem. Numerical results are presented to assess the benefit of opportunistic maintenance and the marginal benefit of considering partial opportunities. Results indicate that significant savings can be achieved by considering OM. Moreover, it is shown that the novel consideration of partial opportunities significantly increase the benefit of OM. - Highlights: • Opportunistic and time-based preventive maintenance jointly optimized. • Non-homogeneous opportunity arrivals and stochastic durations considered. • “Partial” opportunities considered for the first time. • Opportunity duration thresholds used as a decision criterion. • Numerical study conducted to evaluate benefit of optimized policy.

"Tracing China: A Forty-Year Ethnographic Journey"(Hong Kong University Press, 2016—a collection of Siu’s work published over the last twenty years—is not a grandiose showpiece splotched with a lot of paint and colors. Instead, she uses a 2B pencil to leave fine marks on wafer-thin parchment and smudges them ever so slightly, gradually letting the image emerge through the back of the page. If I have understood correctly, though plurality exists in the meanings of “trace,” Siu’s intention with the title Tracing China is less to track the history of China, and more to scrupulously examine every footstep she comes across, no matter how indistinct—to “look for plum blossoms in the snow,” as the Chinese saying goes. This saying might have inspired the Chinese version of the title of the collection, one that preserves a sense of graceful subtlety...

Tornado type closed magnetic trap for an ECR source

CERN Document Server

Abramova, K B; Voronin, A V; Zorin, V G

1999-01-01

We propose to use a Tornado type closed magnetic trap for creation of a source of mul-ticharged ions with plasma heating by microwave radiation. Plasma loss in closed traps is deter-mined by diffusion across the magnetic field, which increases substantially plasma confinement time as compared to the classical mirror trap [1]. We propose to extract ions with the aid of additional coils which partially destroy the closed structure of the magnetic lines in the trap, but don not influence the total confinement time. This allows for producing a controlled plasma flux that depends on the magnetic field of the additional coil. The Tornado trap also possesses merits such as an opportunity to produce high magnetic fields up to 3 T, which makes possible heating and confinement of plasma with a high density of electrons; plasma stability to magneto-hydrodynamic perturbations because the magnetic field structure corresponds to the "min B" configuration; and relatively low costs. All estimates and calculations were carrie...

Magnetic-field fluctuations from 0 to 26 Hz observed from a polar-orbiting satellite

International Nuclear Information System (INIS)

Erlandson, R.E.; Zanetti, L.J.; Potemra, T.A.

1989-01-01

The polar orbit of the Viking satellite provides a unique opportunity to obtain observations of magnetic fluctuations at mid-altitudes on the dayside of the magnetosphere and in the polar-cusp region. One type of magnetic-field fluctuation, observed in the dayside magnetosphere, was Pc 1 waves. Pc 1 waves are in the electromagnetic ion-cyclotron mode and are generated by anisotropies in energetic ion distributions. The waves are thought to be generated near the equator and to propagate large distances along magnetic-field lines. Most observations of Pc 1 waves have been obtained near the equator using geosynchronous satellites and on the surface of the earth. The Viking observations provide an opportunity to observe Pc 1 waves at mid-latitudes above the ionosphere and to determine the spectral structure and polarization of the waves. ULF/ELF broadband noise represents a second type of magnetic fluctuation acquired by Viking. This type of magnetic fluctuation was observed at high latitudes near the polar cusp and may be useful in the identification of polar-cusp boundaries. Thirdly, electromagnetic ion-cyclotron waves have also been observed in the polar-cusp region. These waves occur only during an unusually high level of magnetic activity and appear to be generated locally

Future accelerator magnets will need to reach higher field in the range of 20 T. This field level is very difficult to reach using only Low Temperature Superconductor materials whereas High Temperature Superconductors (HTS) provide interesting opportunities. High current densities and stress levels are needed to design such magnets. YBCO superconductor indeed carries large current densities under high magnetic field and provides good mechanical properties especially when produced using the IBAD approach. The HFM EUCARD program studies the design and the realization of an HTS insert of 6 T inside a Nb$_{3}$Sn dipole of 13T at 4.2 K. In the2HTS insert, engineering current densities higher than 250 MA/m under 19 T are required to fulfill the specifications. The stress level is also very severe. YBCO IBAD tapes theoretically meet these challenges from presented measurements. The insert protection is also a critical because HTS materials show low quench propagation velocities and the coupling with the Nb$_{3}$Sn m...

Full Text Available 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.

In 2015, more than 1 million refugees arrived in Europe. During their travels, refugees often face harsh conditions, violence and torture in transit countries, but there is a lack of quantitative evidence on their experiences. We present the results of a retrospective survey among refugees in the 'Jungle' of Calais, France, to document their health problems and the violence they endured during their journeys. We conducted a cross-sectional population-based survey in November and December 2015. The sample size was set at 402 individuals, and geospatial simple random sampling was used. We collected data on demographics, routes travelled, health status, violence and future plans. Departures from the country of origin increased beginning in September 2015. Sixty-one percent of respondents reported having at least one health problem, especially while in Calais. Overall, 65.6% (95% CI 60.3-70.6) experienced at least one violent event en route; 81.5% of refugees wanted to go to the UK. This first quantitative survey conducted among refugees in Europe provides important socio-demographic data on refugees living in Calais and describes the high rate of violence they encountered during their journeys. Similar documentation should be repeated throughout Europe in order to better respond to the needs of this vulnerable population. © The Author 2017.

Pipe, Teresa Britt

2008-01-01

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.

Coupling magnetic elements to metamaterial structures creates hybrid metamolecules with new opportunities. Here we report on the magnetic control of a metamolecule resonance, by utilizing the interaction between a single split ring resonator (SRR) and a magnetic thin film of permalloy. To suppress eddy current shielding, the permalloy films are patterned into arrays of 30–500 μm diameter discs. Strong hybridized resonances were observed at the anticrossing between the split ring resonance and the ferromagnetic resonance (FMR) of the permalloy. In particular, it is possible to achieve 40 dB modulation of the electric (symmetric) mode of the SRR on sweeping the applied magnetic field through the SRR/FMR anticrossing. The results open the way to the design of planar metamaterials, with potential applications in nonlinear metamaterials, tunable metamaterials and spintronics. (papers)

2006-01-01

To avoid high energy consumption, intensive use of hardware and high cost in the manufacture of nanoparticles encapsulated in carbon, a simple, efficient and economical solution-phase method for the fabrication of FeNi at C nanostructures has been explored. The reaction to the magnetic metal at C structures here is conducted at a relatively low temperature (160 deg. C) and this strategy can be transferred to prepare other transition metal at C core-shell nanostructures. The saturation magnetization of metal in metal at C nanostructures is similar to those of the corresponding buck metals. Magnetic metal at C nanostructures with magnetic metal nanoparticles inside and a functionalized carbon surface outside may not only provide the opportunity to tailor the magnetic properties for magnetic storage devices and therapeutics but also make possible the loading of other functional molecules (e.g. enzymes, antigens) for clinic diagnostics, molecular biology, bioengineering, and catalysis

Close, Frank

2017-01-01

On August 21st, over one hundred million people will gather across the USA to witness the most-watched total solar eclipse in history. Eclipse: Journeys to the Dark Side of the Moon, by popular science author Frank Close, describes the spellbinding allure of this beautiful natural phenomenon. The book explains why eclipses happen, reveals their role in history, literature and myth, and introduces us to eclipse chasers, who travel with ecstatic fervor to some of the most inaccessible places on the globe. The book also includes the author's quest to solve a 3000-year-old mystery: how did the moon move backward during a total solar eclipse, as claimed in the Book of Joshua? Eclipse is also the story of how a teacher inspired the author, aged eight, to pursue a career in science and a love affair with eclipses that has taken him to a war zone in the Western Sahara, the South Pacific, and the African bush. The tale comes full circle with another eight-year old boy - the author's grandson - at the 2017 great Americ...

High energy physics and education are very closely interwoven. Most physics laboratories are located at universities or are operated by consortiums of universities. Fermilab and the SSC are operated by the Universities Research Association, URA, a consortium of 69 major research universities and 3 associate members. Another example of this laboratory and universities relationship is the Continuous Electron Beam Accelerator Facility, CEBAF, which is operated by the Southeastern Universities Research Association, SURA, another consortium of 39 major universities. The education potential inherent in the planning, construction and operation of the SSC is immense. The SSC, as the world's largest scientific instrument and, as the most power accelerator, will have a natural attraction as the preeminent institution in the scientific community. In addition to the primary objective of probing the fundamental composition of matter, the SSC will appear to a broad segment of the population and will create the opportunity for both passive and active educational experiences on the part of staff, students and visitors. On the esoteric level, the SSC will be a magnet for the scientific community and will attract from around the world the finest minds in the field of high energy physics. On the human level, the laboratory will become an integral part of the community and will be an object of great interest to local residents and visitors. The SSC planners should recognize the opportunity to be a contributing institution to both the local and the world community

2018-09-01

Full Text Available Created opportunities are refered as the opportunities in which none of the supply and demand parties exists clearly and obviously one or both of them must be created. Therefore, several economic inventions should take place in marketing, franchising, etc. so that opportunity can be created. This perception of opportunity deals with the creation of new markets. In the meantime, identifying some entrepreneurial actions influencing on the creation of entrepreneurial opportunities can provide backgrounds for the formation and empowering the opportunity creation. In this paper, some basic ideas about the creation of entrepreneurial opportunities and the evolution of opportunity creation theories are examined. Then effective actions on the opportunity creation are identified. Finally, the structure of the investigated actions is examined using the DEMATLE Method. The results which were according to the opinions of 15 experts of entrepreneurship showed that leadership, decision making, and strategy actions influence other entrepreneurial actions.

Neutron Scattering and High Magnetic Fields

The workshop “Neutron Scattering and High Magnetic Fields” was held September 4-5, 2014 at the Oak Ridge National Laboratory (ORNL). The workshop was held in response to a recent report by the National Research Council of the National Academy of Sciences entitled “High Magnetic Field Science and Its Application in the United States: Current Status and Future Directions.”1 This report highlights the fact that neutron scattering measurements carried out in high magnetic fields provide important opportunities for new science. The workshop explored the range of the scientific discoveries that could be enabled with neutron scattering measurements at high fields (25 Tesla or larger), the various technologies that might be utilized to build specialized instruments and sample environment equipment to enable this research at ORNL, and possible routes to funding and constructing these facilities and portable high field sample environments.

Attenuation correction is an essential component of the long chain of data correction techniques required to achieve the full potential of quantitative positron emission tomography (PET) imaging. The development of combined PET/magnetic resonance imaging (MRI) systems mandated the widespread interest in developing novel strategies for deriving accurate attenuation maps with the aim to improve the quantitative accuracy of these emerging hybrid imaging systems. The attenuation map in PET/MRI should ideally be derived from anatomical MR images; however, MRI intensities reflect proton density and relaxation time properties of biological tissues rather than their electron density and photon attenuation properties. Therefore, in contrast to PET/computed tomography, there is a lack of standardized global mapping between the intensities of MRI signal and linear attenuation coefficients at 511 keV. Moreover, in standard MRI sequences, bones and lung tissues do not produce measurable signals owing to their low proton density and short transverse relaxation times. MR images are also inevitably subject to artifacts that degrade their quality, thus compromising their applicability for the task of attenuation correction in PET/MRI. MRI-guided attenuation correction strategies can be classified in three broad categories: (i) segmentation-based approaches, (ii) atlas-registration and machine learning methods, and (iii) emission/transmission-based approaches. This paper summarizes past and current state-of-the-art developments and latest advances in PET/MRI attenuation correction. The advantages and drawbacks of each approach for addressing the challenges of MR-based attenuation correction are comprehensively described. The opportunities brought by both MRI and PET imaging modalities for deriving accurate attenuation maps and improving PET quantification will be elaborated. Future prospects and potential clinical applications of these techniques and their integration in commercial

Positron beams: The journey from fundamental physics to industrial application

Coleman, P.G.

2002-01-01

Monoenergetic beams of positrons developed for fundamental atomic physics experiments have evolved - via basic and applied research in condensed matter physics and chemistry - to a phase in which possibilities for commercial exploitation are becoming apparent. The evolution of positron beam technology, from table-top laboratory-based apparatus with positrons of energies controllable in the 10 0 -10 2 eV energy range and beam intensities of ∼1 s -1 , to systems capable of delivering positrons of energies from 0.02 eV to MeV at intensities as high as 10 8 s -1 , has been both steady and saltatory. The journey from fundamental research to industrial application is a classic example of scientific development; a brief summary of steps on the way is followed by an example in which an attempt is being made to harness the efficacy of positron beams applied to defect spectroscopy of semiconductor structures to create an instrument of value to the ion implantation industry

Harvey, Janice; Michaud, Peter

2012-08-01

Currently in its 7th year (2011) Hawaii's annual Journey through the Universe (JttU) program is a flagship Gemini Observatory public education/outreach initiative involving a broad cross-section of the local Hawai'i Island astronomical community, the public, educators, businesses, local government officials, and thousands of local students. 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.

In retrospect--a reflection on a 50-year research journey.

Howie, John G R

2014-02-01

This essay is a personal review of a research journey extending over 50 years during which time the understanding of medical practice has changed out of all recognition and the quality and standing of the discipline of general practice has improved substantially. Three main bodies of work are reviewed and set against the reasons why they were undertaken. The first, on the pathology of the appendix and the management of possible appendicitis, was carried out almost entirely in the hospital setting. The second, about the prescribing of antibiotics for respiratory illnesses, and the third, about the determinants of good consulting practice, were carried out in general practice. The essay concludes with a reflection on the relevance of the work to some contemporary academic and health service issues. Although the work was carried out in the UK in the context of its National Health Service (NHS), the conclusions are widely generalizable and have contributed to health service and academic developments in many other countries.

Economou, Eleftherios N. [Foundation for Research and Technology Hellas (FORTH), Iraklion (GR). Inst. of Electronic Structure and Laser (IESL)

2011-07-01

This book takes the reader for a short journey over the structures of matter showing that their main properties can be obtained even at a quantitative level with a minimum background knowledge. The latter, besides some high school physics and mathematics, consists of the three cornerstones of science presented in chapters 1 to 3, namely the atomic idea, the wave-particle duality, and the minimization of energy as the condition for equilibrium. Dimensional analysis employing the universal constants and combined with ''a little imagination and thinking'', to quote Feynman, allows an amazing short-cut derivation of several quantitative results concerning the structures of matter. This book is expected to be of interest to physics, engineering, and other science students and to researchers in physics, material science, chemistry, and engineering who may find stimulating the alternative derivation of several real world results, which sometimes seem to pop out the magician's hat.

Advanced electro-magnetic machines and systems require new materials with improved properties. Heterogeneous 3D nanomodified soft magnetic materials could be efficiently applied. Multistage technology of iron particle surface nanomodification by sequential oxidation and Si-organic coatings will be reported. The thickness of layers is 0.5-5 nm. Compaction and annealing are the final steps of magnetic parts and components shaping. The soft magnetic composite material shows the features: resistivity is controlled by insulating coating thickness and equals up to ρ =10-4 Ωṡm for metallic state and ρ =104 Ωṡm for insulator state, maximum magnetic permeability is μm = 2500 and μm = 300 respectively, induction is up to Bm=2.1 T. These properties of composite soft magnetic material allow applying for transformers, throttles, stator-rotor of high-efficient and powerful electric machines in 10 kHz-1MGz frequency range. For microsystems and microcomponents application, good opportunity to improve their reliability is the use of nanocomposite materials. Electroplating technology of nanocomposite magnetic materials into the ultra-thick micromolds will be presented. Co-deposition of the soft magnetic alloys with inert hard nanoparticles allows obtaining materials with magnetic permeability up to μm=104, magnetic induction of Bs=(0.62-1.3) T. Such LIGA-like technology will be applied in MEMS to produce high reliable devices with advanced physical properties.

  The overall aim of this study was to examine nurses' and patients' perceptions of the Magnet model components of transformational leadership and empirical quality outcomes in four Finnish hospitals and to determine if the evidence for transformational leadership and empirical quality outcomes is the same or different in the four hospitals.   This report presents baseline measurements for a longitudinal study of the adaptation of the Magnet model in Finnish hospitals.   Web-based surveys and mailed questionnaires were used in 2008-2009 to collect data from patients (n = 2566) about their satisfaction with care, and from nursing staff about transformational leadership (n = 1151), job satisfaction (n = 2707) and patient safety culture (n = 925) in the selected hospitals.   Awareness of the work of nursing leaders was low. Nurses reported a high level of job satisfaction. Patient safety culture varied considerably between the four hospitals. Patients believed they generally received excellent quality care.   Leadership systems are in transition at the hospitals. Patient safety culture is a complex phenomenon that may be unfamiliar to respondents. The results of the study provide a baseline description to guide the journey toward development of Magnet standards.   Finnish nursing leaders, especially nursing directors, should increase their visibility by working more closely with their staff. They should also pay attention to giving direct feedback about work generally and patient safety issues in particular. © 2012 Blackwell Publishing Ltd.

Plouffe, Brian D; Murthy, Shashi K; Lewis, Laura H

2015-01-01

Magnetic sorting using magnetic beads has become a routine methodology for the separation of key cell populations from biological suspensions. Due to the inherent ability of magnets to provide forces at a distance, magnetic cell manipulation is now a standardized process step in numerous processes in tissue engineering, medicine, and in fundamental biological research. Herein we review the current status of magnetic particles to enable isolation and separation of cells, with a strong focus on the fundamental governing physical phenomena, properties and syntheses of magnetic particles and on current applications of magnet-based cell separation in laboratory and clinical settings. We highlight the contribution of cell separation to biomedical research and medicine and detail modern cell-separation methods (both magnetic and non-magnetic). In addition to a review of the current state-of-the-art in magnet-based cell sorting, we discuss current challenges and available opportunities for further research, development and commercialization of magnetic particle-based cell-separation systems.

On becoming a consultant: A study exploring the journey to consultant practice

International Nuclear Information System (INIS)

Henwood, S.; Booth, L.

2016-01-01

Background: This paper reports a qualitative study exploring the establishment of non-medical consultant roles in Radiography. Given the difficulties reported in recruiting and retaining staff in these posts, we hope this paper offers a historical documentation of those consultants who were some of the first in post, sharing their stories of how they obtained and transitioned into their roles. Methods: This paper is part of a two year case study exploring the leadership domain of consultant practice. The focus of this paper is a reflection, by the consultants, of their journey to becoming a consultant; a documentation of some of the practical issues in establishing the roles; and the transition to higher levels of practice. Eight consultant radiographers participated in the initial interviews (two consultants withdrew from the study subsequent to this). In-depth iterative interviewing was used to explore and record individual stories and experiences. Findings: The consultants shared their perceptions of being in post, including their own motivation to progress to a new role, how prepared they felt initially, the lack of role models, the lack of clarity surrounding the role and a perception of ‘being on display’. Conclusions: The paper offers insight into the journey of these consultants and some of the common characteristics they share. These characteristics give some indication of what motivated them to step into higher level roles, in particular the need to drive change and improvement. The paper also offers suggestions for how the transition into the role could be more effectively supported. - Highlights: • Identifies characteristics thought to contribute to effective consultant practice. • A desire to change practice is a major motivator in applying for a consultant post. • The consultant role was a natural evolution for some, not a desired career pathway. • There is recognition that the initial consultants were pioneers for the profession. �

Catechin-dextran conjugates have recently attracted a lot of attention due to their anticancer activity against a range of cancer cells. Magnetic nanoparticles have the ability to concentrate therapeutically important drugs due to their magnetic-spatial control and provide opportunities for targeted drug delivery. Enhancement of the anticancer efficiency of catechin-dextran conjugate by functionalisation with magnetic iron oxide nanoparticles. Modification of the coating shell of commercial magnetic nanoparticles (Endorem) composed of dextran with the catechin-dextran conjugate. Catechin-dextran conjugated with Endorem (Endo-Cat) increased the intracellular concentration of the drug and it induced apoptosis in 98% of pancreatic tumour cells placed under magnetic field. The conjugation of catechin-dextran with Endorem enhances the anticancer activity of this drug and provides a new strategy for targeted drug delivery on tumour cells driven by magnetic field. The ability to spatially control the delivery of the catechin-dextran by magnetic field makes it a promising agent for further application in cancer therapy.

Homeric Motifs in Cavafy’s Poem »Priam’s Night Journey«

Directory of Open Access Journals (Sweden)

Dragica Fabjan Andritsakos

2016-12-01

Full Text Available The paper discusses Homeric motifs in ‘Priam’s Night Journey’, a poem by the contemporary Greek poet Constantine P. Cavafy and, more precisely, one of the ten poems composed by Cavafy on mythological themes. The discussion begins by comparing Cavafy’s treatment of a motif from the Iliad, Canto 24 – Priam’s journey to Achilles – with its ancient counterpart. The question of Cavafy’s sources is addressed as well: does the poet draw on the Ancient Greek original or on the Modern Greek translation? The second part of the article analyses in detail those passages which closely lean on the ancient epic, and concludes by illustrating Cavafy’s departure from the myth, which emerges most radically in the close of the poem.

The Pre-Raphaelite Journey into the Middle Ages

Full Text Available The Pre-Raphaelite artists and poets rejected contemporary conventional style in art, and did not concern themselves with the representation of contemporary life either. They viewed the surrounding social life as sordid, and reached back to the Middle Ages both for technique and subject matter. Dante Gabriel Rossetti, Holman Hunt, John Everett Millais, and later William Morris found inspiration in late medieval art and literature. They took their subjects from history, legend, religion or poetry, focusing on moral or psychological issues, and expressed fascination for beauty as a value of spiritual nature. This paper examines three of Dante Gabriel Rossetti’s medieval fantasy pictures (The Tune of Seven Towers, The Blue Closet and A Christmas Carol, which prompt a meditative and imaginative response through their enigmatic references, and thus attest the mysterious feature of Pre-Raphaelite medieval imagery. The paper discusses their enigmatic nature in the light of William Morris’s early dream poems The Tune of Seven Towers and The Blue Closet, written on the relevant Rossetti pictures. A parallel reading of poem and picture evidences how Pre-Raphaelite medievalism in painting can invite the onlooker for an inner journey through exploring an imagined referential background.

Uniaxial-pressure dependence of the magnetization dynamics in the high-symmetry single-molecule magnet Mn12-MeOH

The single-molecule magnet [Mn12O12(O2CCH3)16(CH3OH)4]CH3OH (``Mn12-MeOH'') is a high-symmetry sibling of the Mn12-Acetate SMM that offers a prime opportunity to explore the consequences of molecular symmetry. A previous study has shown that applied pressure induced changes in the Mn12-Acetate's anisotropy parameters. Here we present the results of a study in which uniaxial pressure was applied to a crystalline sample of Mn12-MeOH in order to examine how the pressure affects the quantum tunneling of magnetization at low temperature. We find that the pressure induces an increase in the resonant tunneling rate manifested as a change in the height of the tunneling steps in the magnetic hysteresis. These results suggest that pressure is altering symmetry-breaking terms in the molecule's spin Hamiltonian, giving rise to increased tunneling.

Graphene as a flexible template for controlling magnetic interactions between metal atoms.

Metal-doped graphene produces magnetic moments that have potential application in spintronics. Here we use density function theory computational methods to show how the magnetic interaction between metal atoms doped in graphene can be controlled by the degree of flexure in a graphene membrane. Bending graphene by flexing causes the distance between two substitutional Fe atoms covalently bonded in graphene to gradually increase and these results in the magnetic moment disappearing at a critical strain value. At the critical strain, a carbon atom can enter between the two Fe atoms and blocks the interaction between relevant orbitals of Fe atoms to quench the magnetic moment. The control of interactions between doped atoms by exploiting the mechanical flexibility of graphene is a unique approach to manipulating the magnetic properties and opens up new opportunities for mechanical-magnetic 2D device systems.

Industry has been a long-term contributor to the magnetic fusion program, playing a variety of important roles over the years. Manufacturing firms, engineering-construction companies, and the electric utility industry should all be regarded as legitimate stakeholders in the fusion energy program. In a program focused primarily on energy production, industry's future roles should follow in a natural way, leading to the commercialization of the technology. In a program focused primarily on science and technology, industry's roles, in the near term, should be, in addition to operating existing research facilities, largely devoted to providing industrial support to the International Thermonuclear Experimental Reactor (ITER) Project. Industrial opportunities on the ITER Project will be guided by the amount of funding available to magnetic fusion generally, since ITER is funded as a component of that program. The ITER Project can conveniently be discussed in terms of its phases, namely, the present Engineering Design Activities (EDA) phase, and the future (as yet not approved) construction phase. 2 refs., 3 tabs

2018-05-01

Full Text Available Advanced electro-magnetic machines and systems require new materials with improved properties. Heterogeneous 3D nanomodified soft magnetic materials could be efficiently applied. Multistage technology of iron particle surface nanomodification by sequential oxidation and Si-organic coatings will be reported. The thickness of layers is 0.5-5 nm. Compaction and annealing are the final steps of magnetic parts and components shaping. The soft magnetic composite material shows the features: resistivity is controlled by insulating coating thickness and equals up to ρ =10-4 Ω⋅m for metallic state and ρ =104 Ω⋅m for insulator state, maximum magnetic permeability is μm = 2500 and μm = 300 respectively, induction is up to Bm=2.1 T. These properties of composite soft magnetic material allow applying for transformers, throttles, stator-rotor of high-efficient and powerful electric machines in 10 kHz–1MGz frequency range. For microsystems and microcomponents application, good opportunity to improve their reliability is the use of nanocomposite materials. Electroplating technology of nanocomposite magnetic materials into the ultra-thick micromolds will be presented. Co-deposition of the soft magnetic alloys with inert hard nanoparticles allows obtaining materials with magnetic permeability up to μm=104, magnetic induction of Bs=(0.62–1.3 T. Such LIGA-like technology will be applied in MEMS to produce high reliable devices with advanced physical properties.

Cancer: A Personal Journey. Notes from the Edge.The Diary of Peter J. Morgan, M.D.

It is a mistake to think that all personal experiences with cancer are the same. For certain, all cancer patients do confront the possibility of an early death and the prospect of pain and suffering due to the tumor and its treatment. But the specific emotional issues differ with each patient and each family, and the responses to these issues take many forms. In an eloquent and moving film, "Cancer: A Personal Journey. Notes from the Edge.," we are given the privilege of accompanying a remarkable young physician, Peter J. Morgan, on his journey with cancer, a two and one-half year journey that ended with his death at age 31. At age 29, Dr. Morgan, an internist-in-training who intended to pursue a career in hematology and oncology, noted a mass on his leg. Tragically, metastasis to the lungs had already taken place at the time of diagnosis of a synovial sarcoma. There followed the all-too-familiar story of chemotherapy and experimental treatments, pain, debilitation, and ultimately demise, and in itself this experience would move us with the sorrow of a precious life lost. What makes this particular story so remarkable are the insights of this young physician and the struggle for survival of a spirit that would not succumb to the "chaos" of cancer. In the two-year period of his life as a cancer patient, Peter Morgan kept a diary that records his thoughts, his emotional turmoil, and his reflections on life and an untimely death. In particular, we are able to understand the need for his spiritual self to remain alive and to grow despite the deterioration of his physical being. And we see that spiritual triumph in his compelling relationships with his family and his colleagues, in his reflections on art and music and nature, and most of all in his writings and his appreciation of the immense possibilities for joy in life. This is not an easy journey to watch, but the intense sadness of his experience is balanced by his friendships and the great satisfaction he derived

Optimizing Global Coronal Magnetic Field Models Using Image-Based Constraints

Jones-Mecholsky, Shaela I.; Davila, Joseph M.; Uritskiy, Vadim

2016-01-01

The coronal magnetic field directly or indirectly affects a majority of the phenomena studied in the heliosphere. It provides energy for coronal heating, controls the release of coronal mass ejections, and drives heliospheric and magnetospheric activity, yet the coronal magnetic field itself has proven difficult to measure. This difficulty has prompted a decades-long effort to develop accurate, timely, models of the field, an effort that continues today. We have developed a method for improving global coronal magnetic field models by incorporating the type of morphological constraints that could be derived from coronal images. Here we report promising initial tests of this approach on two theoretical problems, and discuss opportunities for application.

Our Journey to Becoming Ethnographers: An Exploration of Rhetorical Structures as Lived Experience

Directory of Open Access Journals (Sweden)

Heather Blair PhD

2011-06-01

Full Text Available This article, originally written as a performative piece, presents the experiences and perceptions of five graduate students and one professor as they reflect on and write about becoming ethnographers throughout a graduate-level research course. Data sources include reflective journals, synthesis papers, and academic literature. Following the completion of the course, the group came together and applied grounded theory to analyze the data and write collectively about their experiences, feelings, and insights on ethnographic work. They present the data as a readers theatre that incorporates portions of a children's book with the group's reflections. Like authors of other academic literature the group discusses the challenges and benefits of ethnographic research. Their collaborative writing reflects their polyvocality as they negotiated their journeys toward becoming ethnographers.

Magnetic shielding of a limiter

Localization of plasma interaction with material surfaces in a separate chamber, from where the escape of impurities is hardly realized, i.e. application of magnetic divertors or pump limiters, is the main technique for reduction of the impurity content in a plasma. In this case, the production of a divertor configuration requires a considerable power consumption and results in a less effective utilization of the magnetic field volume. Utilization of a pump limiter, for example the ICL-type, under tokamak-reactor conditions would result in the extremely high and forbidden local heat loadings onto the limiter surface. Moreover, the magnetically-shielded pump limiter (MSL) was proposed to combine positive properties of the divertor and the pump limiter. The idea of magnetic shielding is to locate the winding with current inside the limiter head so that the field lines of the resultant magnetic field do not intercept the limiter surface. In this case the plasma flows around the limiter leading edges and penetrates into the space under the limiter. The shielding magnetic field can be directed either counter the toroidal field or counter the poloidal one of a tokamak, dependent on the concrete diagram of the device. Such a limiter has a number of advantages: -opportunity to control over the particle and impurity recycling without practical influence upon the plasma column geometry, - perturbation of a plasma column magnetic configuration from the side of such a limiter is less than that from the side of the divertor coils. The main deficiency is the necessity to locate active windings inside the discharge chamber. (author) 5 refs., 3 figs

Topology optimized and 3D printed polymer-bonded permanent magnets for a predefined external field

Topology optimization offers great opportunities to design permanent magnetic systems that have specific external field characteristics. Additive manufacturing of polymer-bonded magnets with an end-user 3D printer can be used to manufacture permanent magnets with structures that had been difficult or impossible to manufacture previously. This work combines these two powerful methods to design and manufacture permanent magnetic systems with specific properties. The topology optimization framework is simple, fast, and accurate. It can also be used for the reverse engineering of permanent magnets in order to find the topology from field measurements. Furthermore, a magnetic system that generates a linear external field above the magnet is presented. With a volume constraint, the amount of magnetic material can be minimized without losing performance. Simulations and measurements of the printed systems show very good agreement.

On magnetic monopoles (without a string) and the Clifford bundle formalism

International Nuclear Information System (INIS)

Recami, E.; Rodrigues, W.A. Jr.

1990-07-01

By adopting the Clifford Bundle language, we recently put forth a satisfactory lagrangian formalism for electromagnetism with magnetic monopoles without a string. Here, by taking advantage of the welcome opportunity of some recent comments by E. Comay (and while answering them), we ''complete'' that formalism. In particular, we show how the Lorentz forces and the motion equations, for both electric and magnetic charges, can be derived from the generalized Maxwell equations: without any further recourse to a variational principle.

A Long Journey of Mathematics and Astronomy in Romania

Science.gov (United States)

Stavinschi, Magda

2010-10-01

Bucharest Astronomical Observatory celebrated recently its centenary. Its founders were all mathematicians or, better said, astronomers specialized in celestial mechanics. Their first doctoral theses were defended at Sorbonne, in the second half of the 19th century, under the guidance of the greatest specialists of the time. After they returned home, they continued what they had begun in Paris, namely celestial mechanics. The instruments they ordered and the first programmes of astronomical observations had an increasingly closer relation to mathematics, as they referred to astrometry and especially to stellar catalogues. Naturally, there were also astrophysical concerns, timid ones in the beginning, and then ever larger, especially beginning with the International Geophysical Year. The evolution of world astronomy, as well as that of Romania, seems to be following but one direction: astrophysics. The truth is that astrometry and celestial mechanics continue to lie at the basis of all astrophysical researches, actually in an entirely new and modern form. The astrometry schools recently organized, the new astrometry textbooks, as well as the IAU working groups dedicated to modern astrometry prove that the long journey of mathematics and astronomy is not over yet.

Learning patient-centred communication: The journey and the territory.

Science.gov (United States)

Cushing, Annie M

2015-10-01

The student entering medical school is about to undergo a socialisation process that profoundly shapes their development as a professional. A central feature is the formal and informal curriculum on the doctor-patient relationship and patient-centred communication. In this paper I will chart some of the features of the student journey which might impact on learning and practice. The medical undergraduate's role is largely that of observer and learner, rather than a provider of care, so much of the formal teaching on patient-centred communication is within simulated practice. Clinical practice environments are the most powerful influences on learning about professional behaviour. Challenges for educational practitioners include how to support authenticity in learners, respond to their agendas, and foster insight to enable flexibility about communication in different contexts. Parallels between the doctor-patient relationship and the student-tutor relationship are explored for their relevance. A number of educational theories can inform curriculum design and educational practice, notably Vygotsky's Zone of Proximal Development. Application of this and other social learning theories, together with students' reflections can enrich our planning of educational interventions and understanding of their impact.

Austrian Economics - The Ultimate Achievement of an Intellectual Journey

Directory of Open Access Journals (Sweden)

Pascal Salin

2009-01-01

Full Text Available In this lecture delivered November 2008 on the occasion of the presentation of the Mises Institute’s Gary G. Schlarbaum Prize for lifetime achievement in the cause of liberty, Professor Salin discusses his discovery of Austrian economics and his involvement in “the world of individual liberty,” and draws various lessons from his intellectual journey. The coherence of Austrian economics appealed to Salin—it is not a patchwork of partial theories, but a logical process of thought founded on realistic assumptions about individual action. Salin also discusses differences between the Chicago and Austrian approaches, and his views about monetary systems.The financial crisis beginning in late 2008 is not a crisis of capitalism, but of state intervention, caused by the expansionary monetary policy of the Fed. Capitalism is the solution, not the cause. There is no need to create money. There is never any balance of payments problem. What is required is tax systems more friendly to capital accumulation, a decrease in the role of the state, the end of monetary policy and, if possible, the disappearing of central banks and the IMF.

The great unknown seven journeys to the frontiers of science

Du Sautoy, Marcus

2016-01-01

Ever since the dawn of civilization we have been driven by a desire to know—to understand the physical world and the laws of nature. The idea that there might be a limit to human knowledge has inspired and challenged scientists and functioned as a spur to innovation. Now, in this dazzling journey through seven great breakthroughs in our understanding of the world, Marcus du Sautoy invites us to consider the outer reaches of human understanding. Are some things beyond the predictive powers of science? Or are those thorny challenges our next breakthroughs? In 1900, Lord Kelvin—who gave the world telegraph cables and the Second Law of Thermodynamics—pronounced that there was “nothing new to be discovered in physics now.” Then came Einstein. Du Sautoy reminds us that again and again major breakthroughs were ridiculed and dismissed at the time of their discovery. He takes us into the minds of the greats and reveals the fraught circumstances of their discoveries. And he carries us on a whirlwind tour of ...

Magnetic Multi-Scale Mapping to Characterize Anthropogenic Targets

Le Maire, P.; Munschy, M.

2017-12-01

The discovery of buried anthropic objects on construction sites can cause delays and/or dangers for workers and for the public. Indeed, every year 500 tons of Unexploded-ordnance are discovered in France. Magnetic measurements are useful to localize magnetized objects. Moreover, it is the cheapest geophysical method which does not impact environment and which is relatively fast to perform. Fluxgate magnetometers (three components) are used to measure magnetic properties bellow the ground. These magnetic sensors are not absolute, so they need to be calibrated before the onset of the measurements. The advantage is that they allow magnetic compensation of the equipment attached to the sensor. So the choice of this kind sensor gives the opportunity to install the equipment aboard different magnetized supports: boat, quad bike, unmanned aerial vehicle, aircraft,... Indeed, this methodology permits to perform magnetic mapping with different scale and different elevation above ground level. An old French aerial military plant was chosen to perform this multi-scale approach. The advantage of the site is that it contains a lot of different targets with variable sizes and depth, e.g. buildings, unexploded-ordnances of the two world wars, trenches, pipes,… By comparison between the different magnetic anomaly maps at different elevations some of the geometric parameters of the magnetic sources can be characterized. The comparison between measured maps at different elevations and the prolonged map highlights the maximum distance for the target's detection (figure).

science, ranging from large-scale structures and dynamics of polymers and biological systems, to electronic properties of today's technological materials. Neutron scattering developed into a vast field, encompassing many different experimental techniques aimed at exploring different aspects of matter's atomic structure and dynamics. Modern magnetic neutron scattering includes several specialized techniques designed for specific studies and/or particular classes of materials. Among these are magnetic reflectometry aimed at investigating surfaces, interfaces, and multilayers, small-angle scattering for the large-scale structures, such as a vortex lattice in a superconductor, and neutron spin-echo spectroscopy for glasses and polymers. Each of these techniques and many others offer exciting opportunities for examining magnetism and warrant extensive reviews, but the aim of this chapter is not to survey how different neutron-scattering methods are used to examine magnetic properties of different materials. Here, we concentrate on reviewing the basics of the magnetic neutron scattering, and on the recent developments in applying one of the oldest methods, the triple axis spectroscopy, that still is among the most extensively used ones. The developments discussed here are new and have not been coherently reviewed. Chapter 2 of this book reviews magnetic small-angle scattering, and modern techniques of neutron magnetic reflectometry are discussed in Chapter 3.

The journey from infertility to parenting multiples: a dream come true?

Science.gov (United States)

Baor, Liora; Blickstein, Isaac

2005-01-01

Infertility deeply affects psychosocial aspects of young couples, who often erroneously take fertility for granted. The inevitable transformation from apparently healthy adults into patients can lead to loss of self-esteem, confidence, health, close relationships, security, and hope. Frequently, when emotional and psychological resources are diminished after prolonged infertility, the couple may express their desperate wish for a family in the form of accepting without reservation the risks of a multiple pregnancy, ignoring the undeniable increased morbidity and mortality associated with these gestations. It is unclear why a couple embarking on the journey of infertility treatment may prefer a pregnancy that is tenfold as likely to have a serious adverse outcome. Of the three potential explanations for such an attitude--desperation, denial, and ignorance--only the last one can be solved with patient education and adequate counseling. At the same time, it is unjustified to avoid assisted reproductive technologies because of potential adverse outcome, however necessary it is to acknowledge the risk of multiple births.

Looking back, looking forward: Recovery journeys in a high secure hospital.

2016-06-01

A qualitative study of staff and service users' views of recovery was undertaken in a UK high secure hospital working to implement recovery practices. 30 staff and 25 service users participated in semi-structured interviews or focus groups. Thematic analysis identified four broad accounts of how recovery was made sense of in the high secure environment: the importance of meaningful occupation; valuing relationships; recovery journeys and dialogue with the past; and recovery as personal responsibility. These themes are discussed with an emphasis on service user strategies of cooperation or resistance, respectively advancing or impeding progress through the system. In this context the notion of cooperation is, for many, commensurate with compliance with a dominant medical model. The policy framing of recovery opens up contemplation of treatment alternatives, more participatory approaches to risk management, and emphasise the value of relational skills, but may not elude the overarching bio-psychiatric episteme. © 2016 Australian College of Mental Health Nurses Inc.

The fundamental aims of the Cassini magnetometer investigation during the Cassini Grand Finale orbits were determination of Saturn's internal planetary magnetic field and the rotation rate of the deep interior. The unique geometry of the orbits provided an unprecedented opportunity to measure the intrinsic magnetic field at close distances never before encountered. The surprising close alignment of Saturn's magnetic axis with its spin axis, known about since the days of Pioneer 11, has been a focus of the team's analysis since Cassini Saturn Orbit Insertion. However, the varying northern and southern magnetospheric planetary period oscillations, which fill the magnetosphere, has been a factor in masking the field signals from the interior. Here we describe an overview of the magnetometer results from the Grand Finale orbits, including confirmation of the extreme axisymmetric nature of the planetary magnetic field, implications for knowledge of the rotation rate and the behaviour of external magnetic fields (arising from the ring current, field aligned currents both at high and low latitudes and the modulating effect of the planetary period oscillations).

Voltage control of magnetism in multiferroic heterostructures.

Science.gov (United States)

Liu, Ming; Sun, Nian X

2014-02-28

Electrical tuning of magnetism is of great fundamental and technical importance for fast, compact and ultra-low power electronic devices. Multiferroics, simultaneously exhibiting ferroelectricity and ferromagnetism, have attracted much interest owing to the capability of controlling magnetism by an electric field through magnetoelectric (ME) coupling. In particular, strong strain-mediated ME interaction observed in layered multiferroic heterostructures makes it practically possible for realizing electrically reconfigurable microwave devices, ultra-low power electronics and magnetoelectric random access memories (MERAMs). In this review, we demonstrate this remarkable E-field manipulation of magnetism in various multiferroic composite systems, aiming at the creation of novel compact, lightweight, energy-efficient and tunable electronic and microwave devices. First of all, tunable microwave devices are demonstrated based on ferrite/ferroelectric and magnetic-metal/ferroelectric composites, showing giant ferromagnetic resonance (FMR) tunability with narrow FMR linewidth. Then, E-field manipulation of magnetoresistance in multiferroic anisotropic magnetoresistance and giant magnetoresistance devices for achieving low-power electronic devices is discussed. Finally, E-field control of exchange-bias and deterministic magnetization switching is demonstrated in exchange-coupled antiferromagnetic/ferromagnetic/ferroelectric multiferroic hetero-structures at room temperature, indicating an important step towards MERAMs. In addition, recent progress in electrically non-volatile tuning of magnetic states is also presented. These tunable multiferroic heterostructures and devices provide great opportunities for next-generation reconfigurable radio frequency/microwave communication systems and radars, spintronics, sensors and memories.

Opportunities for electricity storage in deregulating markets

International Nuclear Information System (INIS)

Graves, F.; Jenkin, T.; Murphy, D.

1999-01-01

This article addresses the value of electricity storage and its ability to take advantage of emerging energy arbitrage opportunities: buying power when it is inexpensive, and reselling it at a higher price. The focus of this article is on electricity markets and the opportunities they present for a merchant storage device, rather than on storage technologies themselves. There are a number of existing and emerging storage technologies: pumped hydro, various batteries, compressed air energy storage (CAES), superconducting magnetic energy storage (SMES), flywheels--even conventional hydro has storage-like properties. However, all these technologies operated on the same basic principle of exploiting short-term differentials in electricity prices: buy low, sell high (a strategy that is actually meaningful in electricity markets, unlike in financial markets). The object of this article is to develop and demonstrate a means for assessing the potential value of storage in different electricity markets, rather than to attempt to assess the prospects of a particular technology. The approach taken here is to look at price data from a number of actual electricity markets to determine what opportunities they might offer to a generic storage device. A storage technology is described here by its basic performance parameters--charge and generate capacity, energy inventory limits, and efficiency--which are sufficient to assess the basic economic potential of storage in a given market. The authors look primarily at US markets, but also compare and contrast findings with the situation in foreign markets in the U.K., Norway, Canada, and Australia, and discuss how market structure can influence the value of storage. Moreover, the authors use empirically observed relationships between hourly and 5 x 16 blocked prices to infer a rule for adjusting the value of storage assets in regions where only blocked price information is available

Cosmology, Embryology and the Journey of Self-Discovery

Directory of Open Access Journals (Sweden)

Tina Lindhard

2017-12-01

Full Text Available On the grounds of a possible parallel between embryogenesis, including the fertilization process, and the development of the Universe, the validity of the Big Bang theory is questioned. In this article, it is suggested that the fundamental nature of the Universe is a cosmic play of opposites, the male and female principle; a polarity, which is inherent in everything as indicated by the yin yang symbol. Even for an electrical charge to exist one needs a positive and negative pole. It also proposes that all matter originates and exists only by virtue of a force that brings all particles to pulsation; a conscious Mind that is expressing itself through ever-changing pulsating forms. Although this invisible spiritual principle behind creation becomes tangible in animals and humans via the heart, it is only the human being who can realize his or her fundamental nature or true Self through a journey of inner discovery. As the development of the Universe might reflect the process the embryo undergoes in forming a body, the principles discussed in this article might also apply to the nature of Nature itself. This implies all of Nature might be a living being or organism, an interconnected whole united through the underlying creative pulsating force. The suggestions put forward here have theological and cosmological implications.

Nerve-muscle activation by rotating permanent magnet configurations.

Science.gov (United States)

Watterson, Peter A; Nicholson, Graham M

2016-04-01

The standard method of magnetic nerve activation using pulses of high current in coils has drawbacks of high cost, high electrical power (of order 1 kW), and limited repetition rate without liquid cooling. Here we report a new technique for nerve activation using high speed rotation of permanent magnet configurations, generating a sustained sinusoidal electric field using very low power (of order 10 W). A high ratio of the electric field gradient divided by frequency is shown to be the key indicator for nerve activation at high frequencies. Activation of the cane toad sciatic nerve and attached gastrocnemius muscle was observed at frequencies as low as 180 Hz for activation of the muscle directly and 230 Hz for curved nerves, but probably not in straight sections of nerve. These results, employing the first prototype device, suggest the opportunity for a new class of small low-cost magnetic nerve and/or muscle stimulators. Conventional pulsed current systems for magnetic neurostimulation are large and expensive and have limited repetition rate because of overheating. Here we report a new technique for nerve activation, namely high-speed rotation of a configuration of permanent magnets. Analytical solutions of the cable equation are derived for the oscillating electric field generated, which has amplitude proportional to the rotation speed. The prototype device built comprised a configuration of two cylindrical magnets with antiparallel magnetisations, made to rotate by interaction between the magnets' own magnetic field and three-phase currents in coils mounted on one side of the device. The electric field in a rectangular bath placed on top of the device was both numerically evaluated and measured. The ratio of the electric field gradient on frequency was approximately 1 V m(-2) Hz(-1) near the device. An exploratory series of physiological tests was conducted on the sciatic nerve and attached gastrocnemius muscle of the cane toad (Bufo marinus). Activation was

Suspensions of magnetic nanoparticles offer diverse opportunities for technology innovation, spanning a large number of industry sectors from imaging and actuation based applications in biomedicine and biotechnology, through large-scale environmental remediation uses such as water purification, to engineering-based applications such as position-controlled lubricants and soaps. Continuous advances in their manufacture have produced an ever-growing range of products, each with their own unique properties. At the same time, the characterisation of magnetic nanoparticles is often complex, and expert knowledge is needed to correctly interpret the measurement data. In many cases, the stringent requirements of the end-user technologies dictate that magnetic nanoparticle products should be clearly defined, well characterised, consistent and safe; or to put it another way—standardised. The aims of this document are to outline the concepts and terminology necessary for discussion of magnetic nanoparticles, to examine the current state-of-the-art in characterisation methods necessary for the most prominent applications of magnetic nanoparticle suspensions, to suggest a possible structure for the future development of standardisation within the field, and to identify areas and topics which deserve to be the focus of future work items. We discuss potential roadmaps for the future standardisation of this developing industry, and the likely challenges to be encountered along the way. (topical review)

In many cases, the stringent requirements of the end-user technologies dictate that magnetic nanoparticle products should be clearly defined, well characterised, consistent and safe; or to put it another way—standardised. The aims of this document are to outline the concepts and terminology necessary for discussion of magnetic nanoparticles, to examine the current state-of-the-art in characterisation methods necessary for the most prominent applications of magnetic nanoparticle suspensions, to suggest a possible structure for the future development of standardisation within the field, and to identify areas and topics which deserve to be the focus of future work items. We discuss potential roadmaps for the future standardisation of this developing industry, and the likely challenges to be encountered along the way.

The WIPP journey to waste receipt

International Nuclear Information System (INIS)

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

1997-01-01

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

Review of the use of magnetic concentrates in geochemical exploration

Science.gov (United States)

Overstreet, W.C.; Day, G.W.

1985-01-01

Magnetic concentrates recovered readily by hand magnet from alluvial sediments or panned concentrates have been used successfully in exploration as a geochemical sample medium for Cu, Zn, Co, Cr, Mo, Ni, V, Sn, and Be, particularly in arid environments where alluvial sediments may be contaminated by aeolian debris. Opportunity for this use arose recently as chemical and spectrographic techniques were developed to determine the abundances of a variety of trace elements in Fe-rich media. The use of analytical data from magnetic concentrates was introduced as one of several anomaly-enhancement techniques based on heavy minerals and intended to identify blind ore deposits. An extensive literature, reviewed here, on the relation of the chemical composition of the mineral magnetite, a main component of magnetic concentrates, to geologic conditions of origin, facilitates the interpretation of trace-element data in the context of association with ore deposits.

This report describes the final results from the DOE Grant DE-SC0007168, “Fast Magnetic Reconnection in HED Laser-Produced Plasmas.” The recent generation of laboratory high-energy-density physics facilities has opened significant physics opportunities for experimentally modeling astrophysical plasmas. The goal of this proposal is to use these new tools to study fundamental problems in plasma physics and plasma astrophysics. Fundamental topics in this area involve study of the generation, amplification, and fate of magnetic fields, which are observed to pervade the plasma universe and govern its evolution. This project combined experiments at DOE laser facilities with kinetic plasma simulation to study these processes. The primary original goal of the project was to study magnetic reconnection using a new experimental platform, colliding magnetized laser-produced plasmas. However through a series of fortuitous discoveries, the work broadened out to allow significant advancement on multiple topics in laboratory astrophysics, including magnetic reconnection, Weibel instability, and collisionless shocks.

Since 2015, Europe has been facing an unprecedented arrival of refugees and migrants: more than one million people entered via land and sea routes. During their travels, refugees and migrants often face harsh conditions, forced detention, and violence in transit countries. However, there is a lack of epidemiological quantitative evidence on their experiences and the mental health problems they face during their displacement. We aimed to document the types of violence experienced by migrants and refugees during their journey and while settled in Greece, and to measure the prevalence of anxiety disorders and access to legal information and procedures. We conducted a cross-sectional population-based quantitative survey combined with an explanatory qualitative study in eight sites (representing the range of settlements) in Greece during winter 2016/17. The survey consisted of a structured questionnaire on experience of violence and an interviewer-administered anxiety disorder screening tool (Refugee Health Screener). In total, 1293 refugees were included, of whom 728 were Syrians (41.3% females) of median age 18 years (interquartile range 7-30). Depending on the site, between 31% and 77.5% reported having experienced at least one violent event in Syria, 24.8-57.5% during the journey to Greece, and 5-8% in their Greek settlement. Over 75% (up to 92%) of respondents ≥15 years screened positive for anxiety disorder, which warranted referral for mental health evaluation, which was only accepted by 69-82% of participants. Access to legal information and assistance about asylum procedures were considered poor to non-existent for the majority, and the uncertainty of their status exacerbated their anxiety. This survey, conducted during a mass refugee crisis in a European Community country, provides important data on experiences in different refugee settings and reports the high levels of violence experienced by Syrian refugees during their journeys, the high prevalence of

2005-01-01

The epoch making discovery of nuclear fission in 1939, which resulted purely from the curiosity driven basic research to understand the atomic and nuclear structure has changed the world forever with the onset of a new era in the history of human civilization. The basic nuclear physics research pursued after the discovery of fission has also been of much relevance in the harnessing of nuclear energy. In the recent years, there is considerable interest towards developing accelerator driven sub-critical reactor systems (ADS) for the incineration of the long-lived spent fuel radioactive waste and for the utilization of thorium fuel for nuclear power generation. In this talk, we discuss important milestones in the journey from discovery of nuclear fission to ADS. (author)

GEMAS: Unmixing magnetic properties of European agricultural soil

High resolution magnetic measurements provide new methods for world-wide characterization and monitoring of agricultural soil which is essential for quantifying geologic and human impact on the critical zone environment and consequences of climatic change, for planning economic and ecological land use, and for forensic applications. Hysteresis measurements of all Ap samples from the GEMAS survey yield a comprehensive overview of mineral magnetic properties in European agricultural soil on a continental scale. Low (460 Hz), and high frequency (4600 Hz) magnetic susceptibility k were measured using a Bartington MS2B sensor. Hysteresis properties were determined by a J-coercivity spectrometer, built at the paleomagnetic laboratory of Kazan University, providing for each sample a modified hysteresis loop, backfield curve, acquisition curve of isothermal remanent magnetization, and a viscous IRM decay spectrum. Each measurement set is obtained in a single run from zero field up to 1.5 T and back to -1.5 T. The resulting data are used to create the first continental-scale maps of magnetic soil parameters. Because the GEMAS geochemical atlas contains a comprehensive set of geochemical data for the same soil samples, the new data can be used to map magnetic parameters in relation to chemical and geological parameters. The data set also provides a unique opportunity to analyze the magnetic mineral fraction of the soil samples by unmixing their IRM acquisition curves. The endmember coefficients are interpreted by linear inversion for other magnetic, physical and chemical properties which results in an unprecedented and detailed view of the mineral magnetic composition of European agricultural soils.

Challenges and opportunities for the next generation of photon regeneration experiments

Photon regeneration experiments searching for signatures of oscillations of photons into hypothetical very weakly interacting ultra-light particles, such as axions, axion-like and hiddensector particles, have improved their sensitivity considerably in recent years. Important progress in laser and detector technology as well as recycling of available magnets from accelerators may allow a big further step in sensitivity such that, for the first time, laser light shining through a wall experiments will explore territory in parameter space that has not been excluded yet by astrophysics and cosmology.We review these challenges and opportunities for the next generation experiments.

Industrial opportunities - offshore

International Nuclear Information System (INIS)

Gerrits, D.J.

1998-01-01

Industrial opportunities available in the Canadian offshore petroleum industry are discussed. Oil has been produced offshore from Nova Scotia since 1992, and offshore from Newfoundland since 1997. Special needs that must be addressed in offshore operations in eastern Canada such as the cold North Atlantic environment, isolation, logistics, safety, and quality assurance, are examined. The most obvious opportunities lie with the designing, building and installing the facilities needed to extract oil and gas from beneath the sea floor and transport it to market. However, there are also opportunities in designing and fabricating clothing, customized food containers and other equipment for offshore needs. Short term opportunities also exist in the decommissioning of depleted production fields and their facilities. One of the greatest obstacles facing new entrants into the offshore oil and gas industry is the lack of a track record. To meet this challenge, the ability to seek out partners to pursue local and international opportunities through joint ventures, strategic alliances and technology sharing partnering arrangements is of great importance. It may be the difference between success and failure. 6 figs

Journeys beyond pages: The use of fiction in tourism

Directory of Open Access Journals (Sweden)

Lipovšek Emilija

2014-01-01

Full Text Available The paper aims at looking into the examples of most popular literary induced tours on the European continent in order to establish interconnectivity between works of fiction as created cultural forms and their impact on tourism industry and consumer society. Accordingly, not only does the human urge to travel refer to the phenomenon of escapism and escapism into fictional, but it is also intrinsically linked to the fact of recreating oneself, i.e. finding one's own destiny/destination. Therefore, the focus is on the acknowledgement that fictional is employed in the non-fictional setting so as to produce man-made tourist attractions. Thus, the illusion of the fictional is perpetuated into the actual places used as attractions for avid readers and cinephiles. For instance, 221b Baker Street in London known as the Sherlock Holmes's home is recreated in reality and made into a museum for those intrigued by the mystery of Conan Doyle's fiction. The tourist is thus perceived both as a consumer and homo ludens in the postmodern contemporary context. The same way as a reader immerses into the text, the tourist embarks on a journey. Thus, various literary tours represent a twofold experience of the fictional world.

The US HEP community has identified the exploitation of physics opportunities at the High Luminosity-LHC (HL-LHC) as the highest near-term priority. Thanks to multi-year R&D programs, US National Laboratories and Universities have taken the leadership in the development of technical solutions to increase the LHC luminosity, enabling the HL-LHC Project and uniquely positioning this country to make critical contributions to the LHC luminosity upgrade. This talk will describe the shaping of the US Program to contribute in the next decade to HL-LHC through newly developed technologies such as Nb3Sn focusing magnets or superconducting crab cavities. The experience gained through the execution of the HL-LHC Project in the US will constitute a pool of knowledge and capabilities allowing further developments in the future. Opportunities for US participations in proposed hadron colliders, such as a possible High Energy-LHC (HE-LHC), will be described as well.

Selection rules for single-chain-magnet behaviour in non-collinear Ising systems

International Nuclear Information System (INIS)

Vindigni, Alessandro; Pini, Maria Gloria

2009-01-01

The magnetic behaviour of molecular single-chain magnets is investigated in the framework of a one-dimensional Ising model with single spin-flip Glauber dynamics. Opportune modifications to the original theory are required in order to account for non-collinearity of local anisotropy axes between themselves and with respect to the crystallographic (laboratory) frame. The extension of Glauber's theory to the case of a collinear Ising ferrimagnetic chain is also discussed. Within this formalism, both the dynamics of magnetization reversal in zero field and the response of the system to a weak magnetic field, oscillating in time, are studied. Depending on the experimental geometry, selection rules are found for the occurrence of slow relaxation of the magnetization at low temperatures, as well as for resonant behaviour of the a.c. susceptibility as a function of temperature at low frequencies. The present theory applies successfully to some real systems, namely Mn-, Dy- and Co-based molecular magnetic chains, showing that single-chain-magnet behaviour is not only a feature of collinear ferro- and ferrimagnetic, but also of canted antiferromagnetic chains.

To compare how registered nurses view the work environment and the nursing shortage based on the Magnet status of their organizations. The upsurge in organizations pursuing and obtaining Magnet recognition provides increased opportunities to investigate whether and how registered nurses who are employed in Magnet organizations and organizations pursuing Magnet status perceive differences in the nursing shortage, hospitals' responses to the shortage, characteristics of the work environment, and professional relationships. A nationally representative sample of registered nurses licensed to practice in the United States was surveyed. The views of registered nurses who worked in Magnet organizations, organizations in the process of applying for Magnet status, and non-Magnet organizations were analyzed as independent groups. Significant differences were found. Although there is a clear Magnet difference, there are also identifiable differences that occur during the pursuit of Magnet recognition. Many organizations in the process of applying for Magnet status rated higher than Magnet organizations, indicating that there is much to do to maintain the comparative advantages for Magnet hospitals.

Neutron scattering—The key characterization tool for nanostructured magnetic materials

The novel properties of materials produced using nanoscale manufacturing processes often arise from interactions across interfaces between dissimilar materials. Thus, to characterize the structure and magnetism of nanoscale materials demands tools with interface specificity. Neutron scattering has long been known to provide unique and quantitative information about nuclear and magnetic structures of bulk materials. Moreover, the specialty techniques of polarized neutron reflectometry and small angle neutron scattering (SANS) with polarized neutron beams and polarization analysis, are ideally and often uniquely suited to studies of nanostructured magnetic materials. Since neutron scattering is a weakly interacting probe, it gives quantifiable and easily-interpreted information on properties of statistically representative quantities of bulk, thin film and interfacial materials. In addition, neutron scattering can provide information to complement that obtained with bulk probes (magnetization, Kerr effect) or surface measurements obtained with scanning probe microscopy or resonant soft x-ray scattering. The straightforward interpretation and the simultaneous availability of structural information, make neutron scattering the technique of choice for the structural and physical characterization of many novel materials, especially those with buried interfaces, ones allowing for isotopic substitutions to decorate buried interfaces, or cases where the magnetic response to an external stimulus can be measured. We describe recent applications of neutron scattering to important thin film materials systems and future opportunities. Unquestionably, neutron scattering has played a decisive role in the development and study of new emergent phenomena. We argue with the advent of new techniques in neutron scattering and sample environment, neutron scattering's role in such studies will become even more dominant. In particular, neutron scattering will clarify and distinguish

Transparency-sharing data or information about outcomes, processes, protocols, and practices-may be the most powerful driver of health care improvement. In this special article, the development and growth of transparency within the National Pediatric Cardiology Quality Improvement Collaborative is described. The National Pediatric Cardiology Quality Improvement Collaborative transparency journey is guided by equal numbers of clinicians and parents of children with congenital heart disease working together in a Transparency Work Group. Activities are organized around four interrelated levels of transparency (individual, organizational, collaborative, and system), each with a specified purpose and aim. A number of Transparency Work Group recommendations have been operationalized. Aggregate collaborative performance is now reported on the public-facing web site. Specific information that the Transparency Work Group recommends centers provide to parents has been developed and published. Almost half of National Pediatric Cardiology Quality Improvement Collaborative centers participated in a pilot of transparently sharing their outcomes achieved with one another. Individual centers have also begun successfully implementing recommended transparency activities. Despite progress, barriers to full transparency persist, including health care organization concerns about potential negative effects of disclosure on reputation and finances, and lack of reliable definitions, data, and reporting standards for fair comparisons of centers. The National Pediatric Cardiology Quality Improvement Collaborative's transparency efforts have been a journey that continues, not a single goal or destination. Balanced participation of clinicians and parents has been a critical element of the collaborative's success on this issue. Plans are in place to guide implementation of additional transparency recommendations across all four levels, including extension of the activities beyond the

[Unpleasant Journey from Helicobacter pylori-associated Gastritis to Gastric Cancer: Cancer Prevention by Taking a Detour].

As a commensal or a pathogen, Helicobacter pylori can change the balance of a complex interaction that exists among gastric epithelial cells, microbes, and their environment. Therefore, unraveling this complex relationship of these mixtures can be expected to help prevent cancer as well as troublesome unmet medical needs of H. pylori infection. Though gastric carcinogenesis is a multi-step process, precancerous lesion can be reversible in the early phase of mucosal damage before reaching the stage of no return. However, biomarkers to predict rejuvenation of precancerous atrophic gastritis have not been identified yet and gastric cancer prevention is still regarded as an impregnable fortress. However, when we take the journey from H. pylori-associated gastritis to gastric cancer, it provides us with the clue for prevention since there are two main preventive strategies: eradication and anti-inflammation. The evidence supporting the former strategy is now ongoing in Japan through a nation-wide effort to eradicate H. pylori in patients with chronic gastritis, but suboptimal apprehension to increasing H. pylori resistance to antibiotics and patient non-compliance still exists. The latter strategy has been continued in the author'sresearch center under siTRP (short-term intervention to revert premalignant lesion) strategy. By focusing on the role of inflammation in the development of H. pylori-associated gastric carcinogenesis, this review is intended to explain the connection between inflammation and gastric cancer. Strategies on H. pylori eradication, removal of inflammation, and reverting preneoplastic lesion will also be introduced. In the end, we expect to be able to prevent gastric cancer by take a detour from the unpleasant journey, i.e. from H. pylori-associated gastritis to gastric cancer.

Los Alamos National Laboratory is a member of a consortium (with Florida State University and the University of Florida) to operate the National High Magnetic Field Laboratory (NHMFL), with funding from the National Science Foundation and the State of Florida. Los Alamos provides unique resources for its component of NHMFL in the form of a 1.4 GW inertial storage motor-generator for high field pulsed magnets and infrastructure for fields generated by flux compression. The NHMFL provides a user facility open to all qualified users, develops magnet technology in association with the private sector, and advances science and technology opportunities. The magnets in service at Los Alamos are of three types. Starting with the pre-existing explosive flux compression capability in 1991, NHMFL added capacitor-driven magnets in December, 1992, and a 20 tesla superconducting magnet in January, 1993. The capacitor-driven magnets continue to grow in diversity and accessibility, with four magnet stations now available for several different magnet types. Two magnets of unprecedented size and strength are nearing completion of assembly and design, respectively. Under final assembly is a quasi-continuous magnet that contains 90 MJ of magnetic energy at full field, and being designed is a non-destructive 100 T magnet containing 140 MJ

Nerve–muscle activation by rotating permanent magnet configurations

Nicholson, Graham M.

2016-01-01

Key points The standard method of magnetic nerve activation using pulses of high current in coils has drawbacks of high cost, high electrical power (of order 1 kW), and limited repetition rate without liquid cooling.Here we report a new technique for nerve activation using high speed rotation of permanent magnet configurations, generating a sustained sinusoidal electric field using very low power (of order 10 W).A high ratio of the electric field gradient divided by frequency is shown to be the key indicator for nerve activation at high frequencies.Activation of the cane toad sciatic nerve and attached gastrocnemius muscle was observed at frequencies as low as 180 Hz for activation of the muscle directly and 230 Hz for curved nerves, but probably not in straight sections of nerve.These results, employing the first prototype device, suggest the opportunity for a new class of small low‐cost magnetic nerve and/or muscle stimulators. Abstract Conventional pulsed current systems for magnetic neurostimulation are large and expensive and have limited repetition rate because of overheating. Here we report a new technique for nerve activation, namely high‐speed rotation of a configuration of permanent magnets. Analytical solutions of the cable equation are derived for the oscillating electric field generated, which has amplitude proportional to the rotation speed. The prototype device built comprised a configuration of two cylindrical magnets with antiparallel magnetisations, made to rotate by interaction between the magnets’ own magnetic field and three‐phase currents in coils mounted on one side of the device. The electric field in a rectangular bath placed on top of the device was both numerically evaluated and measured. The ratio of the electric field gradient on frequency was approximately 1 V m−2 Hz−1 near the device. An exploratory series of physiological tests was conducted on the sciatic nerve and attached gastrocnemius muscle of the cane toad

Bronson Healthcare Group, a 343-bed not-for-profit health care system serving all of southwest Michigan and northern Indiana, has as its flagship Bronson Methodist Hospital, the recipient of the 2005 Malcolm Baldrige National Quality Award. The Baldrige criteria were used to formalize Bronson's approach to performance excellence. The strategic plan is condensed and communicated via a "Plan for Excellence" focused on three strategies: clinical excellence, customer and service excellence, and corporate effectiveness. Initiatives include clinical scene investigation (a system for reporting and investigating sentinel and atypical events), a strategy for educating staff in the Situation-Background-Assessment-Recommendations (SBAR) communication technique, and mandatory influenza immunization for health care staff (safety), patient health literacy needs and a health information center (patient centeredness); methods to reduce bloodstream and ventilator-acquired pneumonia infections (effectiveness); a physician portal for access to forms, test results, and patient information (efficiency); restaurant-style pagers for patients and families while waiting (timeliness); and community outreach (equity). Bronson's journey to excellence continues with more accountability for hand-off communication and teamwork, enhancing a non-punitive environment for patient safety reporting, and further incorporating patient and family involvement.

Full Text Available Land development processes today have an increasing demand to access three-dimensional (3D spatial information. Complex land development may need to have a 3D model and require some functions which are only possible using 3D data. Accordingly, the Intergovernmental Committee on Surveying and Mapping (ICSM, as a national body in Australia provides leadership, coordination and standards for surveying, mapping and national datasets has developed the Cadastre 2034 strategy in 2014. This strategy has a vision to develop a cadastral system that enables people to readily and confidently identify the location and extent of all rights, restrictions and responsibilities related to land and real property. In 2014, the land authority in the state of Victoria, Australia, namely Land Use Victoria (LUV, has entered the challenging area of designing and implementing a 3D digital cadastre focused on providing more efficient and effective services to the land and property industry. LUV has been following the ICSM 2034 strategy which requires developing various policies, standards, infrastructures, and tools. Over the past three years, LUV has mainly focused on investigating the technical aspect of a 3D digital cadastre. This paper provides an overview of the 3D digital cadastre investigation progress in Victoria and discusses the challenges that the team faced during this journey. It also addresses the future path to develop an integrated 3D digital cadastre in Victoria.

The integrated care service coordinated a system of health and social care: primary care, community matrons, social workers, and the voluntary sector. The service was designed to respond to identified cases of high-risk individuals with long-term, multiple, and age-related conditions needing preventive interventions. The video stories were analyzed by researchers in collaboration with service users using a visual thematic qualitative approach. This report is part of an independent analysis of the integrated care service evaluation that used the experience-based codesign model.  Results: The findings are presented in the respective contexts of people with complex conditions and their carers. The overwhelming feelings and emotions of both were loss of control and power throughout their emotional journey, with family carers adopting a protective attitude toward the patients. Their experience of powerlessness was variable throughout their emotional journey. They were affected more strongly when in need of extra help and support and while they were undergoing the process of receiving extra services. When they were receiving help and support outside and within hospitals, some participants were empowered, gaining skills and knowledge by being provided with the mechanisms to cope with their condition at present and in the future.  Conclusion: Feelings of powerlessness were very common among

2011-01-01

A demagnetized Nd-Fe-B permanent magnet was scanned just above the magnetic pole containing the HTS bulk magnet, generating a magnetic field of 3.27 T. The magnet sample was subsequently found to be fully magnetized in the open space of the static magnetic fields. We examined the magnetic field distributions when the magnetic poles were scanned twice to activate the magnetic plates inversely with various overlap distances between the tracks of the HTS bulk magnet. The magnetic field of the 'rewritten' magnet reached the values of the magnetically saturated region of the material, showing steep gradients at the border of each magnetic pole. As a replacement for conventional pulse field magnetizing methods, this technique is proposed to expand the degree of freedom in the design of electromagnetic devices, and is proposed as a novel practical method for magnetizing rare-earth magnets, which have excellent magnetic performance and require intense fields of more than 3 T to be activated.

Gartland, Kevan M A; Gartland, Jill S

2018-06-08

Strategies for biotechnology must take account of opportunities for research, innovation and business growth. At a regional level, public-private collaborations provide potential for such growth and the creation of centres of excellence. By considering recent progress in areas such as genomics, healthcare diagnostics, synthetic biology, gene editing and bio-digital technologies, opportunities for smart, strategic and specialised investment are discussed. These opportunities often involve convergent or disruptive technologies, combining for example elements of pharma-science, molecular biology, bioinformatics and novel device development to enhance biotechnology and the life sciences. Analytical applications use novel devices in mobile health, predictive diagnostics and stratified medicine. Synthetic biology provides opportunities for new product development and increased efficiency for existing processes. Successful centres of excellence should promote public-private business partnerships, clustering and global collaborations based on excellence, smart strategies and innovation if they are to remain sustainable in the longer term.

2018-05-01

Experimental results are presented demonstrating how temperature can influence the dynamics of magnetic nanoparticles (MNPs) in liquid suspension, when exposed to alternating magnetic fields in the kilohertz frequency range. The measurements used to probe the nanoparticle systems are directly linked to both the emerging biomedical technique of magnetic particle imaging (MPI), and to the recently proposed concept of remote nanoscale thermometry using MNPs under AC field excitation. Here, we report measurements on three common types of MNPs, two of which are currently leading candidates for use as tracers in MPI. Using highly-sensitive magnetic particle spectroscopy (MPS), we demonstrate significant and divergent thermal dependences in several key measures used in the evaluation of MNP dynamics for use in MPI and other applications. The temperature range studied was between 296 and 318 Kelvin, making our findings of particular importance for MPI and other biomedical technologies. Furthermore, we report the detection of the same temperature dependences in measurements conducted using the detection coils within an operational preclinical MPI scanner. This clearly shows the importance of considering temperature during MPI development, and the potential for temperature-resolved MPI using this system. We propose possible physical explanations for the differences in the behaviors observed between the different particle types, and discuss our results in terms of the opportunities and concerns they raise for MPI and other MNP based technologies.

Simple derivation of magnetic space groups

The magnetic translation lattices can be described by invariant wave vectors k. Advantages of the wave vector notation over the notations used by Belov et al. and Opechowski et al. are pointed out. In a one-dimensional real representation a space group element (α/tau(1)) has either the character +1 (symmetry element) or -1 (antisymmetry element). Thus the square of any space group operation must have the character +1 in a one-dimensional real representation. This simple ''square criterion'' is used to limit the admissible k-vectors and to derive the family of magnetic space groups, i.e. the set of all possible magnetic space groups, belonging to the same crystallographic space group. In the discussion some useful side results are obtained. Not only the real one-dimensional representations of point groups are connected to real one-dimensional representations of space groups, but a direct connection is shown to exist between one-dimensional complex representations of the point groups 3, 4 and 6 and one-dimensional real representations, belonging to P[001/2]=Psub(2c)(Psub(c))-lattices with screw axes 3 1 , 3 2 , 4 2 , 6 2 and 6 4 . Rules are derived for finding the Belov symbol when the Opechowski-Guccione symbol of the magnetic space group is known and this opportunity is used for correcting errors in the Opechowski-Guccione tables [fr

2018-01-01

Based on an analysis of letters from the Milton Santos collection, the article revisits his journey through exile and shows how he contributed to solidifying the field of critical geography. It also pinpoints elements that reveal the genesis of his intellectual network, which involved thinkers from France, the United States, and Latin America. Focusing on the contexts of his exile, the article links his experiences outside Brazil to new scientific interests and the formation of an international circle of cooperation. Secondarily, it provides evidence of his concern with planning. It is found that his interest in the group of Pierre George and François Perroux was followed by a critical stance that moved him toward dialogue with Marxist philosophy and structuralism.

Promoting equal opportunities at CERN and advising the Director-General on all related matters is the task of the Equal Opportunities Officer, Doris Chromek-Burckhart, and Tim Smith, chair of the Equal Opportunities Advisory Panel. Changes are being introduced: in future, the focus of their work will be broadened to cover all aspects of diversity promotion.   The term "equal opportunities" has always been broader in scope than the equal treatment of men and women but this is what it has traditionally been confined to in practice. "We wanted to change how people see our mission", explains Doris Chromek-Burckhart. The word "diversity" has much wider connotations than "equal opportunities" and makes it clearer that we are also dealing with differences in nationality, religion, age, culture and physical ability”. Getting away from the old clichés is vital to ensuring equal treatment for everyone. The diversit...

From Ideas to Opportunities: Exploring the Construction of Technology-Based Entrepreneurial Opportunities

Directory of Open Access Journals (Sweden)

Ferran Giones

2013-06-01

Full Text Available The transformation of business ideas into market opportunities is at the core of entrepreneurship. Nevertheless, the complexity of such a transformative process is seen to change depending on the variables influencing the opportunity-entrepreneur nexus. Although technology-entrepreneurship is regarded as a force of change and dynamism in socio-economic growth, it also depends upon an intricate process of opportunity development. The interest in understanding better how technology-based entrepreneurs simultaneously cope with technological uncertainty while trying to gain stakeholder support and access to resources, highlights a relevant research gap. The research described in this article uses the constructivist view to deepen our understanding of the technology-based entrepreneur’s conceptualization of the opportunity as a process of social construction. Our results show how initial consensus-building efforts and iteration with knowledgeable peers are an essential part of the emergence of the opportunity, changing both entrepreneur's and stakeholders' perceptions of the early business idea. Consequently, our results provide evidence in support of policy programs and measures that favour social-construction support mechanisms to foster technology-based entrepreneurship.

Engineering electric and magnetic dipole coupling in arrays of dielectric nanoparticles

2018-02-01

Dielectric nanoparticles with both strong electric and magnetic dipole (ED and MD) resonances offer unique opportunities for efficient manipulation of light-matter interactions. Here, based on numerical simulations, we show far-field diffractive coupling of the ED and MD modes in a periodic rectangular array. By using unequal periodicities in the orthogonal directions, each dipole mode is separately coupled and strongly tuned. With this method, the electric and magnetic response of the dielectric nanoparticles can be deliberately engineered to accomplish various optical functionalities. Remarkably, an ultra-sharp MD resonance with sub-10 nm linewidth is achieved with a large enhancement factor for the magnetic field intensity on the order of ˜103. Our results will find useful applications for the detection of chemical and biological molecules as well as the design of novel photonic metadevices.

The Search for QCD Sphalerons and the Chiral Magnetic Effect in Heavy-Ion Collisions with ALICE

CERN Multimedia

CERN. Geneva

2017-01-01

In non-central heavy-ion collisions unprecedented strong magnetic fields, of the order of 10^14 T, are expected to be produced by the incoming protons contained in the nuclei. These fields can be used to detect possible non-conservation of chirality in the QCD sector, a signature of sphaleron transitions. In particular, the interplay of chiral imbalance and magnetic fields results in the separation of positive and negative charges along the direction of the field, a phenomenon called “Chiral Magnetic Effect” (CME). In this seminar, the challenges and the opportunities in the search for the CME and the detection of magnetic fields in heavy-ion collisions will be discussed, with an emphasis on recent ALICE results.

Relationship Between Physical Properties and Magnetism of Soils From Various Pedoenvironments

Jordanova, N.; Jordanova, D.; Todorova, D.; Hirt, A.; Petrov, P.

2009-05-01

Characterization of soils with respect to their fertility, sustainable use and conservation require extensive, time- consuming and costly analyses. Establishment of well defined relationships between certain physical, geochemical and magnetic parameters would be useful tool in pedometrics, giving opportunity to carry out large scale studies on soil properties in more economically effective and fast way. Interdisciplinary analysis of 15 type soils from different pedoenvironments (oxidative, water-logged, salty, etc.) includes extensive magnetic measurements (magnetic susceptibility, anhysteretic (ARM) and isothermal (IRM) remanences, hysteresis parameters); determination of a set of physical characteristics (grain size fractions, pH) and geochemical analyses (total Fe content, oxalate- and dithionite-soluble Fe). Empirical linear relationship is found between soil reaction (pH) and magnetic susceptibility for aerobic soils, and negative relationship between pH and ARM for water-logged soils. Different type soils, showing magnetic enhancement along the solum, show higher ARM intensity with increasing percent of the clay fraction. This feature most probably is related to the fact that pedogenic ferrimagnetic minerals are strongly linked to clay fraction. The absence of such correlation for soils, affected by water-logging conditions suggests prevailing role of amorphous phases and antiferromagnetic Fe oxides in magnetic mineralogy. The role of pedogenic factors for particular behavior of other magnetic parameters will be discussed.

Laser-induced spin protection and switching in a specially designed magnetic dot: A theoretical investigation

Science.gov (United States)

Zhang, G. P.; Si, M. S.; George, T. F.

2011-04-01

Most laser-induced femtosecond magnetism investigations are done in magnetic thin films. Nanostructured magnetic dots, with their reduced dimensionality, present new opportunities for spin manipulation. Here we predict that if a magnetic dot has a dipole-forbidden transition between the lowest occupied molecular orbital (LUMO) and the highest unoccupied molecular orbital (HOMO), but a dipole-allowed transition between LUMO+1 and HOMO, electromagnetically induced transparency can be used to prevent ultrafast laser-induced spin momentum reduction, or spin protection. This is realized through a strong dump pulse to funnel the population into LUMO+1. If the time delay between the pump and dump pulses is longer than 60 fs, a population inversion starts and spin switching is achieved. These predictions are detectable experimentally.

Kim, Christopher S; Spahlinger, David A; Kin, Jeanne M; Coffey, Richard J; Billi, John E

2009-08-01

Lean Thinking is a management philosophy derived from the manufacturing industry, where Toyota has long been the gold standard. Health care organizations have started to apply this approach to patient care. After initial experimentation, the University of Michigan Health System (UMHS) has adopted Lean Thinking as its uniform approach to quality improvement and is striving to become a complete Lean organization. In 2005, the senior leadership selected an initial set of projects in areas that traced the patient's journey across different care settings within our health system. Four of the projects were as follows: orthopedic surgery clinic scheduling, radiation oncology therapy, peripherally inserted central catheter (PICC) services, and coordination of care to the outpatient setting. Lean Thinking encourages service providers to focus on value as defined by the customer and the relentless elimination of waste that impedes the flow of value. A series of learning projects were conducted to test whether Lean methods would work at UMHS. The following factors were found to be key to LEAN PROJECT SUCCESS: expert guidance for initial efforts, leadership in the form of clinical champions and senior management support of the improvement work, frontline worker engagement in mapping out "current state" processes, identifying waste and designing an improved "future state," using metrics to develop and track interventions, and defining realistic project scope. As UMHS's experience applying Lean Thinking to our patient care processes has grown, so have support, enthusiasm, and expertise within the organization. UMHS's Lean Thinking system, now known as the Michigan Quality System, has emerged as the core improvement strategy.

The Paradox of Equal Opportunities

Directory of Open Access Journals (Sweden)

Mitja Sardoč

2014-06-01

Full Text Available The basic assumption of the idea of equal opportunities is based on the assertion that all individuals competing for an advantaged social position should have equal opportunities, i.e., that each and every one of them should have fair opportunities to achieve a particular goal. Despite the fact that equal opportunities is one of the basic mechanisms for a just distribution of advantageous social positions, the idea of fair equality of opportunity remains divided between different competing political projects, e.g., egalitarian liberalism, libertarian political theory, multiculturalism, etc. This paper examines two basic dimensions of equal opportunities to which existing conceptions fail to offer a unanimous answer, i.e., a the issue of fairness and b the issue of the currency of fairness. The concluding part of this paper presents two basic paradoxes that determine both the direction of the discussion as well as the possible solutions to the achievement of fair equal opportunities as part of any process for competing for advantageous social positions.

UTOPISTIC JOURNEY OF POETRY AGAINST HEGEMONIC CORRUPTION A study on the cultural movement of Indonesian poets 434 resisting against corruption through poetry

Full Text Available Hundreds of Indonesian poets have declared a cultural movement to resist against hegemonic corruption through poetry. Poetry is believed to be powerful and thus must have didactic, moral, and utilitarian functions to change society. As Horace said ―dulce and utile‖, literature is supposed to enlighten people and persuade society for a better life. This paper is intended to present the struggle of Puisi Menolak Korupsi (PMK cultural movement during this 4-year journey and what it has gained. 6 anthologies have been published. 47 road shows have run in the entire country to both disseminate the idea and persuade more people to rebuff corruption, and it is still counting. Gauri Viswanathan explained hegemonic control by showing how the humanistic functions traditionally associated with the study of literature can be vital in the process of sociopolitical control. Indonesia was ranked 90 in corruption index 2016 among 176 surveyed countries in the world. Corruption seems to be a hegemonic control to this country, from the top until the bottom level. Corruption becomes hegemonic since it has power and is powerful. The massiveness of hegemonic corruption tends to make this cultural movement of resistance autopistic journey. Faith and spirit are the keys to keep persisting the movement.

2014-01-01

Targeted nanoparticle imaging agents provide many benefits and new opportunities to facilitate accurate diagnosis of cancer and significantly impact patient outcome. Due to the highly engineerable nature of nanotechnology, targeted nanoparticles exhibit significant advantages including increased contrast sensitivity, binding avidity and targeting specificity. Considering the various nanoparticle designs and their adjustable ability to target a specific site and generate detectable signals, nanoparticles can be optimally designed in terms of biophysical interactions (i.e., intravascular and interstitial transport) and biochemical interactions (i.e., targeting avidity towards cancer-related biomarkers) for site-specific detection of very distinct microenvironments. This review seeks to illustrate that the design of a nanoparticle dictates its in vivo journey and targeting of hard-to-reach cancer sites, facilitating early and accurate diagnosis and interrogation of the most aggressive forms of cancer. We will report various targeted nanoparticles for cancer imaging using X-ray computed tomography, ultrasound, magnetic resonance imaging, nuclear imaging and optical imaging. Finally, to realize the full potential of targeted nanotechnology for cancer imaging, we will describe the challenges and opportunities for the clinical translation and widespread adaptation of targeted nanoparticles imaging agents.

Magnetic insights on seismogenic processes from scientific drilling of fault

Science.gov (United States)

Ferre, E. C.; Chou, Y. M.; Aubourg, C. T.; Li, H.; Doan, M. L.; Townend, J.; Sutherland, R.; Toy, V.

2017-12-01

Modern investigations through scientific drilling of recently seismogenic faults have provided remarkable insights on the physics of rupture processes. Following devastating earthquakes, several drilling programs focused since 1995 on the Nojima, Chelungpu, San Andreas, Wenchuan, Nankai Trough, Japan Trench and New Zealand Alpine faults. While these efforts were all crowned with success largely due to the multidisciplinarity of investigations, valuable insights were gained from rock magnetism and paleomagnetism and deserve to be highlighted. Continuous logging of magnetic properties allows detection of mineralogical and chemical changes in the host rock and fault zone particularly in slip zones, whether these are caused by frictional melting, elevation of temperature, ultracataclasis, or post-seismic fluid rock interaction. Further magnetic experiments on discrete samples including magnetic susceptibility, natural remanent magnetization, hysteresis properties, isothermal remanent magnetization acquisition and first order reversal curves, provide additional constrains on the nature, concentration and grain size of magnetic carriers. These experiments typically also inform on magnetization processes by thermal, chemical, or electrical mechanisms. Magnetic fabrics are generally not investigated on fault rocks from drill cores primarily in an effort to conserve the recovered core. However, recent methodological developments now would allow chemically non-destructive anisotropy of magnetic susceptibility (AMS) measurements to be performed on small 3.5 mm cubes. The mini-AMS method could provide crucial information on the kinematics of frictional melts produced during recent or ancient earthquakes and therefore would constrain the corresponding focal mechanisms. Finally, demagnetization experiments of the natural remanent magnetization (NRM) are one of the most powerful items in the magnetic toolkit because they provide chronological constrains on magnetization processes

Galactic forces spiral across the cosmos fueled by nuclear fission and fusion and atoms in plasmatic states with throes of constraints of gravitational forces and magnetic fields, In their wanderings these galaxies spew light, radiation, atomic and subatomic particles throughout the universe. Throughout the ages of man visions of journeying through the stars have been wondered. If humans and human devices from Earth are to go beyond the Moon and journey into deep space, it must be accomplished with like forces of the cosmos such as electrical fields, magnetic fields, ions, electrons and energies generated from the manipulation of subatomic and atomic particles. Forms of electromagnetic waves such as light, radio waves and lasers must control deep space engines. We won't get far on our Earth accustomed hydrocarbon fuels.

2013-03-01

The development of internet of things has brought new opportunities and challenges to the application of RFID tags. Moreover, the Miniaturization application trend of tags at present has become the mainstream of development. In this paper, the double-layer design is to reduce the size of HF antenna, and the magnetic null point of magnetic reconnection region between the RLC resonant circuit and the reader provides sufficient energy to the miniaturization of antenna. The calculated and experimental results show that the miniaturization of HF antennas can meet the reading and writing requirement of the international standard ISO/IEC14443 standard. The results of this paper may make a positive contribution to the applications of RFID technology.

To develop a tool for use in hearing screening and to evaluate the patient journey towards hearing rehabilitation, responses to the hearing aid rehabilitation questionnaire scales aid stigma, pressure, and aid unwanted addressing respectively hearing aid stigma, experienced pressure from others; perceived hearing aid benefit were evaluated with item response theory. The sample was comprised of 212 persons aged 55 years or more; 63 were hearing aid users, 64 with and 85 persons without hearing impairment according to guidelines for hearing aid reimbursement in the Netherlands. Bias was investigated relative to hearing aid use and hearing impairment within the differential test functioning framework. Items compromising model fit or demonstrating differential item functioning were dropped. The aid stigma scale was reduced from 6 to 4, the pressure scale from 7 to 4, and the aid unwanted scale from 5 to 4 items. This procedure resulted in bias-free scales ready for screening purposes and application to further understand the help-seeking process of the hearing impaired. PMID:28028428

The Life Journeys of Young Women Project is the first population-based study to examine the role of economic uncertainty throughout early adulthood on age at first childbirth. A retrospective cross-sectional component was added to an existing cohort study that is based on a birth cohort of women born during 1973-1975 in Adelaide, South Australia (n ∼ 1,000). An event history calendar instrument was used to obtain data regarding a range of life domains including partnering, educational attainment, home ownership, higher education debt, employment, and pregnancies over a 20-year period (sometimes as detailed as at monthly intervals). Interviews were conducted between 2007 and 2009. An analysis framework applying time-varying and time-constant survival analysis techniques within a life-course framework was developed that will guide analyses to examine the role of duration and life-course timing of economic uncertainty on age at first childbirth. This paper discusses study objectives and design, fieldwork procedures, planned statistical analyses, and recruitment outcomes, focusing on novel features that would facilitate analogous epidemiologic research.

Exploiting the valley degree of freedom to store and manipulate information provides a novel paradigm for future electronics. A monolayer transition-metal dichalcogenide (TMDC) with a broken inversion symmetry possesses two degenerate yet inequivalent valleys, which offers unique opportunities for valley control through the helicity of light. Lifting the valley degeneracy by Zeeman splitting has been demonstrated recently, which may enable valley control by a magnetic field. However, the realized valley splitting is modest (∼0.2 meV T -1 ). Here we show greatly enhanced valley spitting in monolayer WSe 2 , utilizing the interfacial magnetic exchange field (MEF) from a ferromagnetic EuS substrate. A valley splitting of 2.5 meV is demonstrated at 1 T by magnetoreflectance measurements and corresponds to an effective exchange field of ∼12 T. Moreover, the splitting follows the magnetization of EuS, a hallmark of the MEF. Utilizing the MEF of a magnetic insulator can induce magnetic order and valley and spin polarization in TMDCs, which may enable valleytronic and quantum-computing applications.

MAGNETIC FLUX TRANSPORT AND THE LONG-TERM EVOLUTION OF SOLAR ACTIVE REGIONS

International Nuclear Information System (INIS)

Ugarte-Urra, Ignacio; Upton, Lisa; Warren, Harry P.; Hathaway, David H.

2015-01-01

With multiple vantage points around the Sun, Solar Terrestrial Relations Observatory (STEREO) and Solar Dynamics Observatory imaging observations provide a unique opportunity to view the solar surface continuously. We use He ii 304 Å data from these observatories to isolate and track ten active regions and study their long-term evolution. We find that active regions typically follow a standard pattern of emergence over several days followed by a slower decay that is proportional in time to the peak intensity in the region. Since STEREO does not make direct observations of the magnetic field, we employ a flux-luminosity relationship to infer the total unsigned magnetic flux evolution. To investigate this magnetic flux decay over several rotations we use a surface flux transport model, the Advective Flux Transport model, that simulates convective flows using a time-varying velocity field and find that the model provides realistic predictions when information about the active region's magnetic field strength and distribution at peak flux is available. Finally, we illustrate how 304 Å images can be used as a proxy for magnetic flux measurements when magnetic field data is not accessible

Alexandrescu, Mioara Mandea; Gilder, Stuart; Courtillot, Vincent; Le Mouël, Jean Louis; Gilbert, Daniel

Birds do it. Bees do it. And with the discovery of lodestone over 2200 years ago, humans too could incorporate the Earth's magnetic field into their daily lives. Some of the oldest applications for tracking the magnetic field were in land and sea navigation. Magnetic field measurements quickly became an important economic factor in world trade, with documented use dating from the 11th century in China.The measurements are important in other applications as well. For example, rapid field variations are generated by solar activity and its interaction with the terrestrial environment. Large magnetic storms can disrupt satellite operation, communication systems, power transmission networks, and so forth [Campbell, 1997].Geomagnetism also provides a unique opportunity to explore the Earth's outer core, which is mostly liquid (molten) iron, where the field is generated. Field measurements can also yield valuable insights into the location of mineral deposits and aid in applications in the petroleum industry.

From home to 'home': Mapping the caregiver journey in the transition from home care into residential care.

Science.gov (United States)

Hainstock, Taylor; Cloutier, Denise; Penning, Margaret

2017-12-01

Family caregivers play a pivotal role in supporting the functional independence and quality of life of older relatives, often taking on a wide variety of care-related activities over the course of their caregiving journey. These activities help family members to remain in the community and age-in-place for as long as possible. However, when needs exceed family capacities to provide care, the older family member may need to transition from one care environment to another (e.g., home care to nursing home care), or one level of care to another (from less intense to more intensive services). Drawing upon qualitative interview data collected in a populous health region in British Columbia, Canada, this study explores the roles and responsibilities of family caregivers for family members making the care transition from home care to residential care. A thematic analysis of the interview transcripts resulted in the development of a conceptual framework to characterize the "Caregiver Journey" as a process that could be divided into at least three phases: 1) Precursors to transition - recognizing frailty in family members and caregivers prior to transition; 2) Preparing to transition into residential nursing home care (RC) and 3) Post-transition: Finding a new balance - where caregivers adjust and adapt to new caregiving responsibilities. Our analyses revealed that the second phase is the most complex involving a consideration of the various activities, and roles that family caregivers take on to prepare for the care transition including: information gathering, advocacy and system navigation. We conclude that there is a need for family caregivers to be better supported during care transitions; notably through ongoing and enhanced investments in strategies to support caregiver communication and education.

Shaping a valued learning journey: Student satisfaction with learning in undergraduate nursing programs, a grounded theory study.

Science.gov (United States)

Smith, Morgan R; Grealish, Laurie; Henderson, Saras

2018-05-01

Student satisfaction is a quality measure of increasing importance in undergraduate programs, including nursing programs. To date theories of student satisfaction have focused primarily on students' perceptions of the educational environment rather than their perceptions of learning. Understanding how students determine satisfaction with learning is necessary to facilitate student learning across a range of educational contexts and meet the expectations of diverse stakeholders. To understand undergraduate nursing students' satisfaction with learning. Constructivist grounded theory methodology was used to identify how nursing students determined satisfaction with learning. Two large, multi-campus, nursing schools in Australia. Seventeen demographically diverse undergraduate nursing students studying different stages of a three year program participated in the study. Twenty nine semi-structured interviews were conducted. Students were invited to describe situations where they had been satisfied or dissatisfied with their learning. A constructivist grounded theory approach was used to analyse the data. Students are satisfied with learning when they shape a valued learning journey that accommodates social contexts of self, university and nursing workplace. The theory has three phases. Phase 1 - orienting self to valued learning in the pedagogical landscape; phase 2 - engaging with valued learning experiences across diverse pedagogical terrain; and phase 3 - recognising valued achievement along the way. When students experience a valued learning journey they are satisfied with their learning. Student satisfaction with learning is unique to the individual, changes over time and maybe transient or sustained, mild or intense. Finding from the research indicate areas where nurse academics may facilitate satisfaction with learning in undergraduate nursing programs while mindful of the expectations of other stakeholders such as the university, nurse registering authorities

Full Text Available Spain’s isolation at the end of the Thirty Year’s War due to the Empire’s separate signature with France and Sweden in the Peace of Westphalia unleashed brief but intense political turmoil between the two Habsburg branches. Although Philip IV and Mariana of Austria’s marriage was ensured, the new Queen’s journey to Spain brought attention to the failure of another engagement between her brother and Emperor’s son, the King of Hungary Ferdinand, and the Infanta Maria Theresa. Given such context, the trip undoubtedly emphasized the tensions between both European powers.

2013-01-01

The Committee to Assess the Current Status and Future Direction of High Magnetic Field Science in the United States was convened by the National Research Council in response to a request by the National Science Foundation. This report answers three questions: (1) What is the current state of high-field magnet science, engineering, and technology in the United States, and are there any conspicuous needs to be addressed? (2) What are the current science drivers and which scientific opportunities and challenges can be anticipated over the next ten years? (3) What are the principal existing and planned high magnetic field facilities outside of the United States, what roles have U.S. high field magnet development efforts played in developing those facilities, and what potentials exist for further international collaboration in this area? A magnetic field is produced by an electrical current in a metal coil. This current exerts an expansive force on the coil, and a magnetic field is "high" if it challenges the str...

Gravity and magnetic analysis provide an opportunity to deduce and understand to a large extent the stratigraphy, structure and shape of the substructure. Euler deconvolution is a useful tool for providing estimates of the localities and depth of magnetic and gravity sources. Wavelet analysis is an interesting tool for filtering and improving geophysical data. The application of these two methods to gravity and magnetic data of the Liberia Basin enable the definition of the geometry and depth of the subsurface geologic structures. The study reveals the basin is sub-divided and the depth to basement of the basin structure ranges from about 5 km at its North West end to 10 km at its broadest section eastward. Magnetic data analysis indicates shallow intrusives ranging from a depth of 0.09 km to 0.42 km with an average depth of 0.25 km along the margin. Other intrusives can be found at average depths of 0.6 km and 1.7 km respectively within the confines of the basin. An analysis of the gravity data indicated deep faults intersecting the transform zone.

A Critical Essay to the selected text – “Araby” What makes the protagonist in “Araby” a lonely person? Has he gained anything from his journey?

Directory of Open Access Journals (Sweden)

Charles Ko

2013-07-01

Full Text Available The present study has been covered an overview and the analysis of the short story “Araby” to find out what makes the protagonist a lonely person, by plot points, characters and themes, and then it has been included a discussion about the gain of the protagonist from the journey. The story starts in the drab life that people live on North Richmond Street. The narrator, a boy who is unnamed, believed to be at the age of around twelve (Cummings, describes the street where he lives at the very beginning of the story. He then thinks about the priest who died in the house before his family moved in, and the games that he and his friends played in the street, recalling how they were running through the back lanes of the houses and hid in the shadows to avoid people in their neighborhood, especially the boy’s uncle, and the sister of his friend Mangan. Mangan’s sister is always in the thoughts of the narrator although they talk little. The paper enables us to have an opportunity to reflect on our life: if we reflect the “gain” again in the more critical direction, we should not regard the loss of innocence as any gain: the innocence that we cannot easily retrieve it from society must be protected before it is lost; to a large extent, innocence may not be negative if we consider it as a source of happiness.

Energy efficiency high speed drives with magnetic bearings; Energieeffizienz durch schnell drehende, magnetgelagerte Antriebe

In modern purification plans the contamination of the wastewater are biologically removed by supplying oxygen. The clarifier is ventilated by compressors around the clock and approximately 60% of the total energy consumption is used for that. It enables a great opportunity for saving energy. This contribution shows that the use of magnetic centrifugal compressors with high-speed drives leads to significant reduction of energy consumption. In addition, the drive is, due to contact free the magnetic bearings, practically wear- and maintenance-free. By the use of integrated sensors in the magnetic bearings a continuous monitoring of the compressor is implemented. Consequently this drive concept provides not only more efficiency and less energy consumption, but also leads to a higher plant availability. (orig.)

This study explored how nursing students can be kept motivated throughout their clinical education. Motivation is a key issue in nursing clinical education for student retention. The study was conducted using grounded theory methods, which are appropriate when studying process in a social context. Sixteen students and four instructors, who were purposefully selected, participated in semistructured interviews. Data were analyzed using the constant comparative method. Students' motivational journey occurred in three steps: (i) social condition; (ii) encountering the clinical education challenges; and (iii) looking for an escape from nursing, or simply tolerating nursing. Struggling with professional identity emerged as the core variable. Iran's social context and many other conditions in the clinical education setting affect students' motivation. Identifying motivational process might assist educational authorities in offering solutions to promote motivation among students. © 2013 Wiley Publishing Asia Pty Ltd.

2011-07-01

The recent development of wind energy project creates opportunities for First Nations. Although they are interested by such projects, First Nations nevertheless have questions such about how they can be a part of the wind industry, what are their rights, what investment would they need to make, and how to judge if they are getting a favourable deal. This presentation aimed at answering those questions an maintained that wind energy would bring social and economic development to First Nations communities as well as diversifying their sources of revenue. Several companies offer their services to First Nations and Anaia Global is a company which helps aboriginal people identify to promote their investment opportunities in renewable energy projects and benefit from the technology transferred to them. This presentation showed that there are significant opportunities for First Nations in the wind energy sector and that Anaia Global is focusing on helping them seize these opportunities.

Logic and memory concepts for all-magnetic computing based on transverse domain walls

International Nuclear Information System (INIS)

Vandermeulen, J; Van de Wiele, B; Dupré, L; Van Waeyenberge, B

2015-01-01

We introduce a non-volatile digital logic and memory concept in which the binary data is stored in the transverse magnetic domain walls present in in-plane magnetized nanowires with sufficiently small cross sectional dimensions. We assign the digital bit to the two possible orientations of the transverse domain wall. Numerical proofs-of-concept are presented for a NOT-, AND- and OR-gate, a FAN-out as well as a reading and writing device. Contrary to the chirality based vortex domain wall logic gates introduced in Omari and Hayward (2014 Phys. Rev. Appl. 2 044001), the presented concepts remain applicable when miniaturized and are driven by electrical currents, making the technology compatible with the in-plane racetrack memory concept. The individual devices can be easily combined to logic networks working with clock speeds that scale linearly with decreasing design dimensions. This opens opportunities to an all-magnetic computing technology where the digital data is stored and processed under the same magnetic representation. (paper)

X-ray and neutron scattering techniques are capable of acquiring information about the structure and dynamics of quantum matter. However, the high-field magnet systems currently available at x-ray and neutron scattering facilities in the United States are limited to fields of 16 tesla (T) at maximum, which precludes applications that require and/or study ultra-high field states of matter. This gap in capability—and the need to address it—is a central conclusion of the 2005 National Academy of Sciences report by the Committee on Opportunities in High Magnetic Field Science. To address this gap, we propose a magnet development program that would more than double the field range accessible to scattering experiments. With the development and use of new ultra-high field–magnets, the program would bring into view new worlds of quantum matter with profound impacts on our understanding of advanced electronic materials.

Role of 4 f electrons in crystallographic and magnetic complexity

Science.gov (United States)

Pathak, Arjun K.; Paudyal, Durga; Mudryk, Yaroslav; Pecharsky, Vitalij K.

2017-08-01

The functionality of many magnetic materials critically depends on first manipulating and then taking advantage of highly nonlinear changes of properties that occur during phase transformations. Unique to lanthanides, property-defining 4 f electrons are highly localized and, as commonly accepted, play little to no role in chemical bonding. Yet here we demonstrate that the competition between 4 f -electron energy landscapes of Dy (4 f9 ) and Er (4 f11 ) is the key element of the puzzle required to explain complex interplay of magnetic and structural features observed in E r1 -xD yxC o2 , and likely many other mixed lanthanide systems. Unlike the parent binaries—DyC o2 and ErC o2 —E r1 -xD yxC o2 exhibits two successive magnetostructural transitions: a first order at TC, followed by a second order in the ferrimagnetically ordered state. Supported by first-principles calculations, our results offer new opportunities for targeted design of magnetic materials with multiple functionalities, and also provide a critical insight into the role of 4 f electrons in controlling the magnetism and structure of lanthanide intermetallics.
