    2016-06-01

    As the French nuclear industry is facing a major challenge (financial weakness, an electric power market in crisis, 15 years without building any reactor, delayed works), this report first outlines why innovation is necessary to guarantee a low carbon and competitive electricity, to comfort the leadership position of this sector in the world, and to respond to expectations of civil society. Then, it describes how the French nuclear industry is already implementing organisational, technological and social innovations, notably through the development of digital technologies. The third part identifies priorities of new public policies: to imagine a new business model for nuclear (a better visibility for investors, taking all induced costs in the power system into account in a diversified mix, reform of the carbon market, taking avoided atmospheric pollution into account), to rethink regulation in order to free innovation spirit, and to prepare the future by investing in research

    The Mexican Nuclear Research Institute (ININ) played an important role in setting up of nuclear power plants (two) and development of fuel technology. However, with no current plans for expansion of this programme, the Institute is looking mainly into multi-cycle fuel management and life extension issues. The Institute focuses on programmes related to radioisotope and radiation applications and on the use of nuclear technologies for non-nuclear applications. The ININ is the major provider of radioisotopes for medical uses. It also promotes and uses nuclear analytical techniques for addressing a variety of problems. In non-nuclear areas some R and D examples include: the use of thermal plasma for hazardous waste incineration, biodegradation of polymers and development of separation techniques for treating industrial effluents. For preservation of knowledge, the Institute has instituted PhD. programmes in materials science, medical physics and nuclear science in collaboration with a university. (author)

  11. Radiation doses in pediatric computed tomography procedures: challenges facing new technologies

    International Nuclear Information System (INIS)

    Cotelo, E.; Padilla, M.; Dibarboure, L.

    2008-01-01

    Despite the fact that in recent years an increasing number of radiologists and radiological technologists have been applying radiation dose optimization techniques in paediatric Computed Tomography (CT) examinations, dual and multi -slice CT (MSCT) scanners present a new challenge in Radiation Protection (RP). While on one hand these scanners are provided with Automatic Exposure Control (AEC) devices, dose reduction modes and dose estimation software, on the other hand Quality Control (QC) tests and CT Kerma Index (C) measurements and patient dose estimation present specific difficulties and require changes or adaptations of traditional QC protocols. This implies a major challenge in most developing countries where Quality Assurance Programmes (QAP) have not been implemented yet and there is a shortage in the number of medical physicists This paper analyses clinical and technical protocols as well as patient doses in 204 CT body procedures performed in 154 children. The investigation was carried out in a paediatric reference hospital of Uruguay, where are performed an average of 450 paediatric CT examinations per month in a sole CT dual scanner. Besides, C VOL reported from the scanner display was registered in order to be related with the same dosimetric quantity derived from technical parameters and C values published on tables. Results showed that not all the radiologists applied the same protocol in similar clinical situations delivering unnecessary patient dose with no significant differences in image quality. Moreover, it was found that dose reduction modes represent a drawback in order to estimate patient dose when mA changes according to tissue attenuation, in most cases in each rotation. The study concluded on the importance of QAP that must include education on RP of radiologists and technologists, as well as in the need of medical physicists to perform QC tests and patient dose estimations and measurements.

    2015-02-01

    This study aims to identify other challenges besides those already faced by students, in seven polytechnics in Malaysia as a continuation to the previous research that had identified 52 main challenges faced by students using the Rasch Model. The explorative study focuses on the challenges that are not included in the Mooney Problem Checklist (MPCL). A total of 121 polytechnic students submitted 183 written responses through the open questions provided. Two hundred fifty two students had responded from a students' perspective on the dichotomous questions regarding their view on the challenges faced. The data was analysed qualitatively using the NVivo 8.0. The findings showed that students from Politeknik Seberang Perai (PSP) gave the highest response, which was 56 (30.6%) and Politeknik Metro Kuala Lumpur (PMKL) had the lowest response of 2 (1.09%). Five dominant challenges were identified, which were the English language (32, 17.5%), learning (14, 7.7%), vehicles (13, 7.1%), information technology and communication (ICT) (13, 7.1%), and peers (11, 6.0%). This article, however, focus on three apparent challenges, namely, English language, vehicles, as well as computer and ICT, as the challenges of learning and peers had been analysed in the previous MPCL. The challenge of English language that had been raised was regarding the weakness in commanding the aspects of speech and fluency. The computer and ICT challenge covered the weakness in mastering ICT and computers, as well as computer breakdowns and low-performance computers. The challenge of vehicles emphasized the unavailability of vehicles to attend lectures and go elsewhere, lack of transportation service in the polytechnic and not having a valid driving license. These challenges are very relevant and need to be discussed in an effort to prepare polytechnics in facing the transformational process of polytechnics.

    Technology empowerment” means that innovation is increasingly accessible to ordinary people of limited means. As powerful technologies become more affordable and accessible, and as people are increasingly connected around the world, ordinary people are empowered to participate in the process of innovation and share the fruits of collaborative innovation. This annotated briefing describes technology empowerment and focuses on how empowerment may create challenges to U.S. national security. U.S. defense research as a share of global innovation has dwindled in recent years. With technology empowerment, the role of U.S. defense research is likely to shrink even further while technology empowerment will continue to increase the speed of innovation. To avoid falling too far behind potential technology threats to U.S. national security, U.S. national security institutions will need to adopt many of the tools of technology empowerment.

    The amount of water per person in northern China is less than half of that in Egypt, a country with very scarce water resources. Clearly, then, China is one of the regions on our planet that is going to have to face severe problems of water supply in the future. Rapid urbanisation and industrialisation growing agricultural output, environmental degradation, climatic instability, a large population density and worsening regional disparities are all factors that will challenge the management and utilisation of China's water resources in the years to come.

  11. The Face Management Challenges of Sport Celebrity

    Directory of Open Access Journals (Sweden)

    Diana-Luiza DUMITRIU

    2015-03-01

    Full Text Available While gaining centrality within the sport field, media accelerated its commodification process and facilitated sport actors becoming competitive on the celebrity market. The aim of this paper is to discuss the reconfiguration that the celebrity logic brought in terms of the mere condition of the sport actor and the face management challenges and remedial strategies that he has to cope with. I will thus focus on two main dimensions that I find to be constitutive for the celebrity status: one related to the augmented media exposure that sport stars are subject to and to the corollary symbolic reconfiguration of the boundaries between his public and his private life, and the second one related to the vulnerability that comes along with the new visibility of the complex repertoire of identities and social roles performed by the sport actors. Within this last dimension of the sport-related celebrity cycle of promotion, I will lay stress not only on the face threatening aspects for the sport stars, but also on the vulnerability transfer within the affinal branding network and the challenges it could bring for the brands that chose to associate their image with a sport celebrity. Thus, I argue that the kaleidoscopic public figures of sport celebrities requires high impression management involvement on their part, as well as more caution on the marketeers part.

  12. Psychosocial challenges facing physicians of today.

    Science.gov (United States)

    Arnetz, B B

    2001-01-01

    Fundamental changes in the organization, financing, and delivery of health care have added new stressors or opportunities to the medical profession. These new potential stressors are in addition to previously recognized external and internal ones. The work environment of physicians poses both psychosocial, ergonomic, and physico-chemical threats. The psychosocial work environment has, if anything, worsened. Demands at work increase at the same time as influence over one's work and intellectual stimulation from work decrease. In addition, violence and the threat of violence is another major occupational health problem physicians increasingly face. Financial constraint, managed care and consumerism in health care are other factors that fundamentally change the role of physicians. The rapid deployment of new information technologies will also change the role of the physician towards being more of an advisor and information provider. Many of the minor health problems will increasingly be managed by patients themselves and by non-physician professionals and practitioners of complementary medicine. Finally, the economic and social status of physicians are challenged which is reflected in a slower salary increase compared to many other professional groups. The picture painted above may be seen as uniformly gloomy. In reality, that is not the case. There is growing interest in and awareness of the importance of the psychosocial work environment for the delivery of high quality care. Physicians under stress are more likely to treat patients poorly, both medically and psychologically. They are also more prone to make errors of judgment. Studies where physicians' work environment in entire hospitals has been assessed, results fed-back, and physicians and management have worked with focused improvement processes, have demonstrated measurable improvements in the ratings of the psychosocial work environment. However, it becomes clear from such studies that quality of the

  14. Four Challenges That Global Health Networks Face

    Directory of Open Access Journals (Sweden)

    Jeremy Shiffman

    2017-04-01

    Full Text Available Global health networks, webs of individuals and organizations with a shared concern for a particular condition, have proliferated over the past quarter century. They differ in their effectiveness, a factor that may help explain why resource allocations vary across health conditions and do not correspond closely with disease burden. Drawing on findings from recently concluded studies of eight global health networks—addressing alcohol harm, early childhood development (ECD, maternal mortality, neonatal mortality, pneumonia, surgically-treatable conditions, tobacco use, and tuberculosis—I identify four challenges that networks face in generating attention and resources for the conditions that concern them. The first is problem definition: generating consensus on what the problem is and how it should be addressed. The second is positioning: portraying the issue in ways that inspire external audiences to act. The third is coalition-building: forging alliances with these external actors, particularly ones outside the health sector. The fourth is governance: establishing institutions to facilitate collective action. Research indicates that global health networks that effectively tackle these challenges are more likely to garner support to address the conditions that concern them. In addition to the effectiveness of networks, I also consider their legitimacy, identifying reasons both to affirm and to question their right to exert power.

  15. Facing Global Challenges with Materials Innovation

    2017-10-01

    The path of society evolution has long been associated with a growing demand for natural resources and continuous environmental degradation. During the last decades, this pace has accelerated considerably, despite the general concern with the legacy being left for the next generations. Looking ahead, the predicted growth of the world population, and the improvement of life conditions in most regions, point to an increasing demand for energy generation, resulting in additional pressure on the Earth's sustainability. Materials have had a key role in decreasing the use of natural resources, by either improving efficiency of existing technologies or enabling the development of radical new ones. The greenhouse effect (CO2 emissions) and the energy crisis are global challenges that can benefit from the development of new materials for the successful implementation of promising technologies and for the imperative replacement of fossil fuels by renewable sources.

It is characterized by a craving for physical training, resulting in uncontrollable excessive exercise behavior with harmful consequences, such as injuries and impaired social relations. It has not been accepted as a mental disorder in either International Classification of Diseases or Diagnostic and Statistical Manual of Mental Disorders. The aim of this literature review was to critically examine the research on links (comorbidity, risks (negative consequences, and challenges faced (problems in a treatment context. This review found that compulsive exercise is associated with eating disorder pathology, perfectionism, neuroticism, narcissism, and obsessive compulsive traits. The most prominent negative consequences were injuries, social impairment, and depression, but more research is needed to uncover the potential dysfunction resulting from compulsive exercise. As the condition is not recognized as a psychiatric disorder, studies on treatment interventions are sparse. Problems with compliance have been reported; therefore, motivational interviewing has been proposed as a treatment approach, in combination with cognitive behavioral therapy. This review summarizes and discusses findings on links/comorbidity, risks/negative consequences, and treatment challenges. We suggest that future studies should pay attention to both prevention and counseling in sports settings, where compulsive exercise

    Among the numerous challenges facing our modern world, perhaps the most urgent and dominant are energy related. From the perspective of developing countries they are, in order of priorities, development, energy security and environment. Oil covers above 38% of the global commercial energy needs and gas about 20%. In some commanding sectors of the economy, like transport, oil is for now virtually the irreplaceable source of energy. In addition, oil and gas are two valuable primary materials of the chemical industry. It also happens that oil consumption is one of the sources of environmental pollution through the emission of CO 2 . Utilisation of the world's finite fossil energy resources (88% of total commercial energy) in the service of development reflects all the negative attributes of the mismanagement of the global economy, exemplified by waste, inefficiency, unfair terms of trade, market instability and short-sighted policies. These serious inequities have been further compounded by the growing menace of environmental and climatic degradation. In dealing with the interactions between these three complex systems, i.e., energy, environment and development, it is important for oil producers to delineate their priorities clearly, if they are to disentangle credible common goals for an international convention.

    Belicza, B

    1997-01-01

    Considering the present health policy, health service and health care systems, health condition and health demands of the people, proclaimed priorities in biomedical scientific research in the Republic of Croatia, and expected health and disease status in the first decades of the 21st century, the author raises the question of sensitization of the Croatian physicians and the public to new ethical challenges. These questions are arousing attention in the world and Europe as one of the peculiarities mankind is facing in the midst of new scientific, technical and informatic possibilities, at the same time in the context of global impoverishment and restricted public funds, with existing or expected changes in the demographic structure and the life philosophy system of values. In democratic, pluralistic societies, the dimension of human rights is getting increasingly pronounced. This is reflected in the postulation of international, national or professional bioethical standards related to biomedical research, in the emphasis on the indisputable public right to actively make decisions by consensus mechanisms about goals, priorities and limits of individual and collective health care programmes, forms and levels of medical care in the national health service and obligatory health insurance system, as well as about ethical aspects of the relation doctor-patient, at the boundary of the interactions of doctor-patient-profession-individual-community-society relationships.

  19. An Introduction to Face Recognition Technology

    2000-01-01

    Full Text Available Recently face recognition is attracting much attention in the society of network multimedia information access.  Areas such as network security, content indexing and retrieval, and video compression benefits from face recognition technology because "people" are the center of attention in a lot of video.  Network access control via face recognition not only makes hackers virtually impossible to steal one's "password", but also increases the user-friendliness in human-computer interaction.  Indexing and/or retrieving video data based on the appearances of particular persons will be useful for users such as news reporters, political scientists, and moviegoers.  For the applications of videophone and teleconferencing, the assistance of face recognition also provides a more efficient coding scheme.  In this paper, we give an introductory course of this new information processing technology.  The paper shows the readers the generic framework for the face recognition system, and the variants that are frequently encountered by the face recognizer.  Several famous face recognition algorithms, such as eigenfaces and neural networks, will also be explained.

    Agriculture faces many challenges to maximize yields while it is required to operate in an environmentally sustainable manner. In the present study, we analyze the major agricultural challenges identified by European farmers (primarily related to biotic stresses) in 13 countries, namely Belgium, Bulgaria, the Czech Republic, France, Germany, Hungary, Italy, Portugal, Romania, Spain, Sweden, UK and Turkey, for nine major crops (barley, beet, grapevine, maize, oilseed rape, olive, potato, sunflower and wheat). Most biotic stresses (BSs) are related to fungi or insects, but viral diseases, bacterial diseases and even parasitic plants have an important impact on yield and harvest quality. We examine how these challenges have been addressed by public and private research sectors, using either conventional breeding, marker-assisted selection, transgenesis, cisgenesis, RNAi technology or mutagenesis. Both national surveys and scientific literature analysis followed by text mining were employed to evaluate genetic engineering (GE) and non-GE approaches. This is the first report of text mining of the scientific literature on plant breeding and agricultural biotechnology research. For the nine major crops in Europe, 128 BS challenges were identified with 40% of these addressed neither in the scientific literature nor in recent European public research programs. We found evidence that the private sector was addressing only a few of these "neglected" challenges. Consequently, there are considerable gaps between farmer's needs and current breeding and biotechnology research. We also provide evidence that the current political situation in certain European countries is an impediment to GE research in order to address these agricultural challenges in the future. This study should also contribute to the decision-making process on future pertinent international consortia to fill the identified research gaps.

    1986-01-01

    The recovery of the Three Mile Island Unit 2 facilities has transformed decontamination from traditional ''mop-and-bucket'' cleaning into an advanced technology. The decontamination of the reactor building and auxiliary and fuel handling building required the development of new methodologies, adaptation of equipment from other fields, and the development of new equipment to meet the projects goals. Experience at TMI-2 has resulted in the development of techniques for; radiological characterization with wide angle detectors and autoradiograhic techniques for the determination of sources and depth of contamination penetration, coatings and base surface removal with ultra-high-pressure water dissolution chemicals and mechanical scabblers (paint-chipping devices), and surface decontamination with high-pressure steam vacuum extraction. This paper presents an overview of the development of decontamination technology and its impact on the TMI-2 program. The benefits of expanding the TMI-2 experience to general use in the nuclear industry are discussed

  20. Heart transplantation: challenges facing the field.

    Science.gov (United States)

    Tonsho, Makoto; Michel, Sebastian; Ahmed, Zain; Alessandrini, Alessandro; Madsen, Joren C

    2014-05-01

    There has been significant progress in the field of heart transplantation over the last 45 years. The 1-yr survival rates following heart transplantation have improved from 30% in the 1970s to almost 90% in the 2000s. However, there has been little change in long-term outcomes. This is mainly due to chronic rejection, malignancy, and the detrimental side effects of chronic immunosuppression. In addition, over the last decade, new challenges have arisen such as increasingly complicated recipients and antibody-mediated rejection. Most, if not all, of these obstacles to long-term survival could be prevented or ameliorated by the induction of transplant tolerance wherein the recipient's immune system is persuaded not to mount a damaging immune response against donor antigens, thus eliminating the need for chronic immunosuppression. However, the heart, as opposed to other allografts like kidneys, appears to be a tolerance-resistant organ. Understanding why organs like kidneys and livers are prone to tolerance induction, whereas others like hearts and lungs are tolerance-resistant, could aid in our attempts to achieve long-term, immunosuppression-free survival in human heart transplant recipients. It could also advance the field of pig-to-human xenotransplantation, which, if successful, would eliminate the organ shortage problem. Of course, there are alternative futures to the field of heart transplantation that may include the application of total mechanical support, stem cells, or bioengineered whole organs. Which modality will be the first to reach the ultimate goal of achieving unlimited, long-term, circulatory support with minimal risk to longevity or lifestyle is unknown, but significant progress in being made in each of these areas.

  2. New mask technology challenges

    Kimmel, Kurt R.

    2001-09-01

    Mask technology development has accelerated dramatically in recent years from the glacial pace of the last three decades to the rapid and sometimes simultaneous introductions of new wavelengths and mask-based resolution enhancement techniques. The nature of the semiconductor business has also become one driven by time-to-market as an overwhelming factor in capturing market share and profit. These are among the factors that have created enormous stress on the mask industry to produce masks with enhanced capabilities, such as phase-shifting attenuators, sub-resolution assist bars, and optical proximity correction (OPC) features, while maintaining or reducing cost and cycle time. The mask can no longer be considered a commodity item that is purchased form the lowest-cost supplier. Instead, it must now be promoted as an integral part of the technical and business case for a total lithographic solution. Improving partnership between designer, mask-maker, and wafer lithographer will be the harbinger of success in finding a profitable balance of capability, cost, and cycle time. Likewise for equipment infrastructure development, stronger partnership on the international level is necessary to control development cost and mitigate schedule and technical risks.

    2014-11-01

    This study employed the Model of Technology Preference (MTP) to explain the relationship of the variables as the antecedents of behavioral intention to adopt a social networking site (SNS) for communication. Self-administered questionnaires were distributed to SNS account users using paper-based and web-based surveys that led to 514 valid responses. The data were analyzed using structural equation modeling (SEM). The results show that two out of three attributes of the attribute-based preference (ATRP) affect attitude-based preference (ATTP). The data support the hypotheses that perceived enjoyment and social presence are predictors of ATTP. In this study, the findings further indicated that ATTP has no relationship with the behavioral intention of using SNS, but it has a relationship with the attitude of using SNS. SNS development should provide features that ensure enjoyment and social presence for users to communicate instead of using the traditional face-to-face method of communication.

    2006-12-01

    Full Text Available Purpose and Objective: The South African automotive component industry faces huge challenges in a very competitive global market. The primary focus of this research article is to determine the challenges facing exporters within this industry with special reference to selected sub-sectors. The challenges are approached from a supply chain perspective only. Problem Investigated: The research problem of this study was to identify these unique challenges and ascertain whether the implementation of a 'philosophy of continuous improvement' could be used as a strategic tool to address the challenges they face in the market. Methodology: This study included a combination of literature review, interviews with managers in the selected sub-groups and questionnaires sent out to determine the challenges facing automotive component exporters. In order to test the content validity and the reliability of the questionnaire, a pilot study was conducted at two organisations that are the main suppliers of automotive filters for passenger vehicles. The non-probability convenience sample technique was used to select the sample and consisted of selected sub-sectors that contribute 64,1% of the total value of automotive component exports in South Africa. Out of twenty-seven questionnaires sent out, twenty (74% response rate were duly completed by the respondents and returned to the researcher. Findings: South Africa faces unique challenges and these are listed and ranked according to priority from most to least important as follows: 1. The reduction of production costs; 2. R/US$ exchange rate effect on the respondent's export sales and profit margin; 3. Exchange rate fluctuations; 4. Threats to the local automotive component market; and 5. Increased competition by way of manufactured imports being sold in the South African market. Value of Research: The study provides recommendations that can be used within the automotive component industry.

  12. Challenges faced by nuclear research centres in Indonesia

    Subki, I.R.; Soentono, S.

    2001-01-01

    Nuclear research centres in Indonesia are mainly owned and operated by the National Nuclear Energy Agency, covering basically various research and development facilities for non-energy and energy related activities. The research and development activities cover a broad spectrum of basic, applied, and developmental research involving nuclear science and technology in supporting various fields ranging from basic human needs, e.g. food and health; natural resources and nuclear and environmental safety; as well as industry. Recent economic crisis, triggered by monetary turmoil, has dictated the IAEA to face new challenges and to give more efforts on the application of the so called 'instant technology' i.e. the technology which has been developed and is ready for implementation, especially on food and health, to be better utilized to overcome various problems in the society. Various short and medium term programmes on the application of isotopes, radiation, and nuclear techniques for non-energy related activities have emerged in accord with these efforts. In this regard, besides the intensification of the instant technology implementation on food and health, the nuclear research and development on food plant mutation, fertilizers, radio-vaccines, production of meat and milk, production processes of various radiopharmaceuticals, and radioisotopes as well as radiation processing related to agro-industry have to be intensified using the available laboratories processing facilities. The possibility of the construction of irradiators for post harvesting processes in some provinces is being studied, while the designing and manufacturing of various prototypes of devices, equipment, and instruments for nuclear techniques in health and industry are continued. Considering the wide applications of accelerators for non-energy and energy related research and development, construction of accelerator-based laboratories is being studied. In energy related research the feasibility of

  13. Challenges Facing Crop Production And (Some) Potential Solutions

    Science.gov (United States)

    Schnable, P. S.

    2017-12-01

    To overcome some of the myriad challenges facing sustainable crop production we are seeking to develop statistical models that will predict crop performance in diverse agronomic environments. Crop phenotypes such as yield and drought tolerance are controlled by genotype, environment (considered broadly) and their interaction (GxE). As a consequence of the next generation sequencing revolution genotyping data are now available for a wide diversity of accessions in each of the major crops. The necessary volumes of phenotypic data, however, remain limiting and our understanding of molecular basis of GxE is minimal. To address this limitation, we are collaborating with engineers to construct new sensors and robots to automatically collect large volumes of phenotypic data. Two types of high-throughput, high-resolution, field-based phenotyping systems and new sensors will be described. Some of these technologies will be introduced within the context of the Genomes to Fields Initiative. Progress towards developing predictive models will be briefly summarized. An administrative structure that fosters transdisciplinary collaborations will be briefly described.

    Increasing attention is directed towards thermonuclear fusion as a possible future energy source. Major advantages of this energy conversion technology are the almost inexhaustible resources and the option to produce energy without CO2-emissions. However, in the most advanced field of magnetic plasma confinement a number of technological challenges have to be met. In particular high-temperature resistant and plasma compatible materials have to be developed and qualified which are able to withstand the extreme environments in a commercial thermonuclear power reactor. The plasma facing materials (PFMs) and components (PFCs) in such fusion devices, i.e. the first wall (FW), the limiters and the divertor, are strongly affected by the plasma wall interaction processes and the applied intense thermal loads during plasma operation. On the one hand, these mechanisms have a strong influence on the plasma performance; on the other hand, they have major impact on the lifetime of the plasma facing armour. In present-day and next step devices the resulting thermal steady state heat loads to the first wall remain below 1 MWm-2; the limiters and the divertor are expected to be exposed to power densities being at least one order of magnitude above the FW-level, i.e. up to 20 MWm-2 for next step tokamaks such as ITER or DEMO. These requirements are responsible for high demands on the selection of qualified PFMs and heat sink materials as well as reliable fabrication processes for actively cooled plasma facing components. The technical solutions which are considered today are mainly based on the PFMs beryllium, carbon or tungsten joined to copper alloys or stainless steel heat sinks. In addition to the above mentioned quasi-stationary heat loads, short transient thermal pulses with deposited energy densities up to several tens of MJm-2 are a serious concern for next step tokamak devices. The most frequent events are so-called Edge Localized Modes (type I ELMs) and plasma disruptions

    Full Text Available Bajo el enfoque del Modelo Ecotecnológico observado en las comunidades artesanales de Galapa y Usiacurí del Departamento de Atlántico; Colombia, se presentan las dimensiones que caracterizan lo artesanal. En ambas comunidades se elaboran máscaras en madera y artesanías en palma de iraca, respectivamente, las cuales han persistido a los retos de la globalización. Sin embargo, la capacidad de estos artesanos ha sido perturbada por la dinámica económica basada en el mercado, que les exige niveles de producción y utilización excesiva de recursos naturales, conduciéndolos a una ruptura entre el patrimonio cultural material, la memoria tecnológica y el balance ecológico de recursos naturales utilizados. El modelo se construye a partir de datos cualitativos obtenidos mediante instrumentos participativos sistematizados en una matriz de análisis estructural, para dar cuenta de las relaciones de incidencia y dependencia de las dimensiones del modelo. Los resultados se sintetizan en un instrumento que permite tomar decisiones sobre la productividad cultural, tecnológica y ecológica de la producción artesanal.An eco-technological model was used to determine aspects of artisanal production in the rural communities of Galapa and Usiacurí, located in the Department of Atlántico, Colombia. Galapa produces wooden masks and Usiacurí, handcrafts made with the Iraca palm. Both communities are facing the challenges of globalization and the capacity of their artisans has been affected by market economy dynamics, which demand high levels of production and excessive use of natural resources. This has led to a rupture between material cultural patrimony, technological memory, and ecological balance of natural resources used. The model draws from qualitative data obtained through participatory instruments, which are then systematized in a structural analysis matrix to determine the impact and inter-dependency of the different aspects covered in the

    2015-01-01

    Full Text Available Rice is the most economically important food crop in many developing countries and has also become a major crop in many developed countries where its consumption has increased considerably. It has become necessary to meet the demand of the world’s current population growth rate, and the least costly means for achieving this aim is to increase rice productivity, wherever possible. The main challenges encountered by rice processors in Nigeria are to find appropriate solutions for quality rice processing. Therefore this work provides basic information about the challenges of rice processing and focuses on the challenges faced by the small scale rice processors and reasons for continuous rice importation with a view to guiding decision-making to be self-sufficient in rice production, thereby making some improvement in Nigerian economy.

  17. Challenges Facing Healthwatch, a New Consumer Champion in England.

    Science.gov (United States)

    Carter, Pam; Martin, Graham

    2016-01-21

    This article engages with debates about the conceptualisation and practical challenges of patient and public involvement (PPI) in health and social care services. Policy in this area in England has shifted numerous times but increasingly a consumerist discourse seems to override more democratic ideas concerning the relationship between citizens and public services. Recent policy change in England has seen the creation of new consumer champion bodies in the form of local Healthwatch. The article describes these new organisational structures for PPI and shows how those who seek to influence planning and delivery of services or comment or complain about aspects of their care face considerable complexity. This is due, in part, to the ambiguous remit set out for newly instigated Healthwatch organisations by government. Drawing on governance theory, we show that it can also be understood as a function of an increasingly polycentric governance arena. Challenges that flow from this include problems of specifying jurisdictional responsibility, accountability, and legitimacy. We review Healthwatch progress to date, then we set out four challenges facing local Healthwatch organisations before discussing the implications of these for patients and the public. The first challenge relates to non-coterminous boundaries and jurisdictional integrity. Secondly, establishing the unique features of Healthwatch is problematic in the crowded PPI arena. The third challenge arises from limited resources as well as the fact that resources flow to Healthwatch from the local authorities that Healthwatch are expected to hold to account. The fourth challenge we identify is how local Healthwatch organisations negotiate the complexity of being a partner to statutory and other organisations, while at the same time being expected to champion local people's views. © 2016 by Kerman University of Medical Sciences.

    Full Text Available Higher education refers to the subsequent training to high school education; that is undergraduate and graduate; whose mission is to preserve; develop and disseminate culture. Throughout the history of higher education it has undergone a process of transformation; mainly due to the development of knowledge and the transformation of society. In the process they highlighted two great moments; in the first; which culminated in the mid-twentieth century; it conceived the higher education institution encompassing all knowledge of society; and who graduated was ready to perform professionally throughout life; the second time; after those dates; it is conceivable that knowledge is no longer exclusive to the institution of higher education; and there can be no efficient performance without continuous training and continuous updating of knowledge. The objective of this work is to point out the general goals and some strategies of the students’ formation of superior education; to confront the big challenges that it faces today the society. To define this goals and strategies four challenge levels are considered: a physical; structural and politicalideological challenges; b challenges around the scientifictechnician and of the knowledge advances; c challenges of the internal structure of the formative process and the access to the superior education; and d challenges in the formation of values in the students.

    The future information systems are expected to be more intelligent and will take human queries in natural language as input and answer them promptly. To develop a chatbot or a computer program that can chat with humans in realistic manner to extent that human get impressions that he/she is talking with other human is a challenging task. To make such chatbots, different technologies will work together ranging from artificial intelligence to development of semantic resources. Sophisticated chatbots are developed to perform conversation in number of languages. Arabic chatbots can be helpful in automating many operations and serve people who only know Arabic language. However, the technology for Arabic language is still in its infancy stage due to some challenges surrounding the Arabic language. This paper offers an overview of the chatbot application and the several obstacles and challenges that need to be resolved to develop an effective Arabic chatbot.

    On 16 May, AEA Technology became the corporate name under which the UK Atomic Energy Authority will conduct all of its marketing and commercial operations. The names symbolises more than a cosmetic change. It marks a letting go of the authority's old and familiar image of a government-funded institution involved in atomic research. Its new identity is that of an innovative and commercially-minded organisation offering R and D, advanced engineering and specialist consultancy services over a wide range of technologies. AEA Technology will target its marketing efforts at its aerospace; defence; electricity supply industry; manufacturing; process industries; oil and gas; environmental; and safety and reliability areas.

    Technical and scientific support organizations (TSOs) dedicated to supporting national regulatory authorities. At present BAPETEN has internal TSOs. Pertaining to the regulatory control of nuclear safety, security, and safeguards for nuclear power plants (NPPs), independent TSOs providing support to the safety regulatory bodies are facing a number of technical challenges to ensuring the safety of NPPs. It is essential that BAPETEN need independent TSOs in order to warrant a sufficient level of safety, security and non proliferation in building and operating of first NPP.

  5. Challenges when electricity markets face the investment phase

    Finon, Dominique; Johnsen, Tor Arnt; Midttun, Atle

    2004-01-01

    Deregulation of electricity industry in Europe has tended to start with a grace period of energy surplus inherited from the previously expansive coordinated economies and further amplified by better resource utilisation from extended international trade. The regulatory challenge has therefore primarily been to allocate existing generation to consumers in an efficient way. However, as energy demand increases, due to economic growth, the challenge of providing new capacity surfaces. The Nordic region, which has been a pioneer in internationalising and deregulating electricity, is now approaching this stage, ahead of most of the rest of Europe. While the Nordic case is characterised by specificities related to hydropower it also raises the more general challenge of capacity expansion under a deregulated market economy. The article therefore discusses how the Nordic investment challenges of today shed light on more generic challenges that may become more general European challenges of tomorrow. In a final section, the article discusses policy options available to address the investment/price-hike challenge. The argument is put forward that recursion to some degree of coordinated governance might seem necessary if solutions are confined within large-scale technical systems. However, within the context of a small-scale decentralised technological development, one may be more confident of competitive solutions

  6. The Challenges Faced by New Science Teachers in Saudi Arabia

    Science.gov (United States)

    Alsharari, Salman

    Growing demand for science teachers in the Kingdom of Saudi Arabia, fed by increasing numbers of public school students, is forcing the Saudi government to attract, recruit and retain well-qualified science teachers. Beginning science teachers enter the educational profession with a massive fullfilment and satisfaction in their roles and positions as teachers to educating children in a science classroom. Nevertheless, teachers, over their early years of practice, encounter numerous challenges to provide the most effective science instruction. Therefore, the current study was aimed to identify academic and behavioral classroom challenges faced by science teachers in their first three years of teaching in the Kingdom of Saudi Arabia. In addition, new science teacher gender, school level and years of teaching experience differences in perceptions of the challenges that they encountered at work were analyzed. The present study also investigated various types of support that new science teachers may need to overcome academic and behavioral classroom challenges. In order to gain insights about ways to adequately support novice science teachers, it was important to examine new science teachers' beliefs, ideas and perceptions about effective science teaching. Three survey questionnaires were developed and distributed to teachers of both sexes who have been teaching science subjects, for less than three years, to elementary, middle and high school students in Al Jouf public schools. A total of 49 novice science teachers responded to the survey and 9 of them agreed to participate voluntarily in a face-to-face interview. Different statistical procedures and multiple qualitative methodologies were used to analyze the collected data. Findings suggested that the top three academic challenges faced by new science teachers were: poor quality of teacher preparation programs, absence of appropriate school equipment and facilities and lack of classroom materials and instructional

    Most migratory songbirds travel between their breeding areas and wintering grounds through a series of nocturnal flights. The timing of their departures defines the potential flight duration and thus the distance covered during a migratory night. Yet, migratory songbirds show substantial variation in their nocturnal departure timing. With this study, we aim to assess whether the respective challenges of the migration route, namely its distance and nature, help to explain this variation. At a stopover site, we caught Northern Wheatears (Oenanthe oenanthe) of two subspecies that differ in distance and nature of their onward migration route in spring, but not in autumn. We determined the start of their nocturnal migratory restlessness during short-term captivity, and radiotracked their nocturnal departure timing after release in both migration seasons. Northern Wheatears started their nocturnal migratory restlessness earlier when facing a long remaining migration distance and an extended sea barrier in spring. Individual departure directions generally affected the nocturnal departure timing with early departures being directed towards the respective migratory destination. In spring, this pattern was predominantly found in birds carrying relatively large fuel stores, but was absent in lean birds. At the same time, birds facing a short remaining migration distance and no extended sea barrier strongly reacted to relatively large fuel stores by an early start of nocturnal migratory behaviour (migratory restlessness and departure timing), whereas this reaction was not found in birds facing a long remaining migration distance and sea barrier. These results suggest that the basic diel schedule of birds' migratory activity is adapted to the onward migration route. Further, they suggest that birds adjust their behavioural response, that is start of nocturnal migratory behaviour, to fuel stores in relation to their impending migratory challenges. This is a substantial step in

    The numerous research programmes looking at new-generation biofuels that were initiated over the last ten years are now starting to bear fruit. Although no plants are producing and marketing biofuels yet, the large-scale, industrial feasibility of second-generation bio-fuel production at competitive cost may be demonstrated in the short-term. As far as third generation biofuels derived from algal biomass are concerned, there is a great deal of R and D interest in the sector, but the technology is still only in its infancy. (author)

    Developing countries like India require a huge infrastructure to facilitate needs of the people. Construction industry provides several opportunities to the individuals. Construction manager work is to supervise and organize the construction activities in construction projects. Now a day construction manager facing challenges. This paper aimed to study the challenges facing by the construction manager in the perception of construction professionals. 39 variables were taken from the literature review which found to be severe impact on construction managers’ performance. Construction manager, project manager and site engineers are the respondents for this survey. Using SPSS, regression analysis was done and recognized significant challenges. These challenges were classified into 5 domains. In management challenges, resource availability and allocation, risks and uncertainties existing in the project onsite, top management support and cost constraints are the most significant variables. In skills requirement of a construction manager challenges, technical skills required to learn and adapt new technology in the project, decision making and planning according to the situation in site are the most significant variables. In performance challenges, implementation of tasks according to the plan is the important variable whereas in onsite challenges, manage project risks, develop project policies and procedures are the most important.

    This study examines challenges faced by refugee new parents from Africa in Canada. Refugee new parents from Zimbabwe (n = 36) and Sudan (n = 36) were interviewed individually about challenges of coping concurrently with migration and new parenthood and completed loneliness and trauma/stress measures. Four group interviews with refugee new parents (n = 30) were subsequently conducted. Participants reported isolation, loneliness, and stress linked to migration and new parenthood. New gender roles evoked marital discord. Barriers to health-related services included language. Compounding challenges included discrimination, time restrictions for financial support, prolonged immigration and family reunification processes, uncoordinated government services, and culturally insensitive policies. The results reinforce the need for research on influences of refugees' stressful experiences on parenting and potential role of social support in mitigating effects of stress among refugee new parents. Language services should be integrated within health systems to facilitate provision of information, affirmation, and emotional support to refugee new parents. Our study reinforces the need for culturally appropriate services that mobilize and sustain support in health and health related (e.g., education, employment, immigration) policies.

    Florini, Ann; Sovacool, Benjamin K.

    2009-01-01

    This article conceptualizes the energy problems facing society from a global governance perspective. It argues that a notion of 'global energy governance,' taken to mean international collective action efforts undertaken to manage and distribute energy resources and provide energy services, offers a meaningful and useful framework for assessing energy-related challenges. The article begins by exploring the concepts of governance, global governance, and global energy governance. It then examines some of the existing institutions in place to establish and carry out rules and norms governing global energy problems and describes the range of institutional design options available to policymakers. It briefly traces the role of a selection of these institutions, from inter-governmental organizations to summit processes to multilateral development banks to global action networks, in responding to energy issues, and points out their strengths and weaknesses. The article concludes by analyzing how the various approaches to global governance differ in their applicability to addressing the conundrums of global energy problems.

    Azer, Samy A

    2005-12-01

    One of the main tasks of a problem-based learning (PBL) tutor is to facilitate group discussion. Group facilitation is about process rather than content. In this process, a tutor helps the group increase their skills and progress in their discussion. Several studies have highlighted strategies and training used in preparing PBL tutors. However, PBL tutors usually feel that it is not that easy to change their teaching style to the PBL format. They are sometimes unsure about their role or what strategy they might use to facilitate their students' discussion. This article in the '12 Tips' series is a detailed description of, and provides answers to, common challenges faced by PBL tutors. The tips provided in this manuscript should help tutors with practical answers. The article may be useful to PBL tutors, medical and health educators and those responsible for PBL training workshops.

    2017-12-01

    Water management in the Western United States relies significantly upon a fleet of small to very large engineered dams to store water during times of runoff and distribute that water during times of need. Much of this infrastructure is Federally owned and/or operated, and was designed and funded during the first half of the twentieth century through a complex set of repayment contracts for Federally authorized purposes addressing water supply, recreation, and hydropower, and other water management objectives. With environmental laws, namely the Endangered Species Act, and other environmental concerns taking a more active role in water resources in the mid to latter half of the twentieth century, this infrastructure is being stressed even greater than anticipated to provide authorized purposes. Additionally, weather and climate norms being experienced are certainly near the edges, if not outside, of anticipated variability in the climate and hydrology scenarios for which the infrastructure was designed. And, finally, these dams, economically designed for a lifespan of 50 - 100 years, are experiencing maintenance challenges from routine to significant. This presentation will focus on identifying some of the history and challenges facing the water infrastructure in the Western United States. Additionally, some perspectives on future paths to meet the needs of western irrigation and hydropower production will be provided.

    2009-01-01

    The introduction of liberalization, the increasing share of decentralized electricity generation, the aging of electrical infrastructures, ambitious generation objectives and technological evolution are the key drivers that require substantial investments in the distribution grid. The most urgent challenges are to adapt the network architecture and operation, modernize and improve metering equipment, renovate existing facilities. The Energy Regulatory Commission sets the price to be paid by users of the distribution grid; this price is set rather low, in order to encourage the system operator to make productivity gains. But resultant low income may deprive the operator of the financial resources needed to adapt the system to the new conditions. (authors)

    2017-02-01

    The purpose of this article is to describe the characteristics and experiences of individuals who use technology to support telephone or face-to-face communication after total laryngectomy. An online questionnaire was used to identify potential participants. Seventeen individuals met inclusion criteria and participated in an in-depth survey. They were compared with a reference group matched for age, gender, and time postsurgery who did not use these technologies. Open-ended responses were summarized. Compared with the matched reference group, individuals who used technology to support verbal communication had undergone more aggressive cancer treatment and used more communication methods. They were less likely to use an alaryngeal speech method, had greater difficulty over the telephone, and used more repair strategies in face-to-face communication. The 2 groups did not differ significantly in the frequency or success of their communication, however. Open-ended responses revealed great variety with regard to their reasons, purposes, and timing of technology use. There is a subset of individuals using technology to support verbal communication very successfully after laryngectomy. Usage was not limited to those who were unable to communicate verbally and often continued long after the initial postoperative period in many settings, for various purposes, and in combination with other methods of communication.

    In Singapore, employees aged 62-65 can continue to be employed if they meet the re-employment eligibility criteria. This policy, coupled with an ageing workforce, calls for age-friendly initiatives, specific to work-related challenges faced by older nurses. To determine work-related challenges faced by older nurses. A mixed method sequential explanatory study was conducted with nurses, aged 50 and above, working in a healthcare cluster in Singapore. In the quantitative phase, a questionnaire was administered to 534 nurses to elicit work-related challenges, then in-depth interviews with 30 nurses were carried out to help explain why certain tasks and work circumstances became harder. Results of the survey indicated that the top three challenges were coping with changes, working with computers and reading labels. Place of work, salary range, gender and race were significantly associated with different work-related challenges. Five themes emerged from the qualitative data: physical demands of work and workload, new technology, need for further education, working with younger nurses and in intercultural teams, and changing public expectations and professional image. The study supports the current literature on the challenges older nurses face with technological advancement. However, older nurses in our study reported less aches and pain as compared to that reported elsewhere. There is a need for specific strategies that will address changes in work processes and environment in order to retain older nurses. When devising age-friendly work improvement initiatives, it is important for nurse leaders to factor in the needs of nurses working in different care environments, who are of different ranks, or are from different ethnic backgrounds. © 2017 International Council of Nurses.

    Full Text Available Museums are part of a wider cultural and entertainment environment, which is ruled by highly demanding visitors who seek immersive experiences (edutainment and time-saving arrangement. This has encouraged and, in some opinions, forced museums to turn their focus from collections to visitors. In addition, museums have faced competition and new technologies in the form of virtual museums and virtual reality. This has emphasized the need to accept marketing as a survival tool and to make it into a link between museums and visitors. This article attempts to give current insights into museum marketing as part of the arts marketing field. Its aim is also to identify and explain some of the major challenges and opportunities facing everyday museum business, in order to provide insight into the complex world of museum marketing. Former findings about the development of museum marketing and its biggest changes and challenges are presented, summarized and analyzed.

    Current post-secondary school students have access to multiple help-seeking sources. As help-seeking behaviour relates to academic achievement, the provision of preferred help sources would be beneficial to students, instructors, and course designers. This study examines whether students prefer and intend to utilize technologically mediated or face-to-face help-seeking sources. Participants (n = 226) were recruited from two sections of an on campus, introductory, educational psychology class. An online survey was distributed containing measures of help-seeking threat, adaptive help-seeking tendencies, avoidant help-seeking tendencies, and the intention to seek help from six sources. Correlations and an ANOVA were calculated to determine whether source preferences differed by self-reported course grade. Help-seeking threat was only negatively associated with sources of help that required face-to-face interaction. Despite the threat, students intended to use face-to-face help-seeking sources more than technologically mediated sources. Students intended to seek help the most before or after class, via email, or during class. Students intended to seek help the least through the discussion board and during online office hours. Higher performing students preferred face-to-face sources, particularly before or after class and during class, more than lower performing students. Lower performing students intended to use mediated sources especially the discussion board and online office hours more than the higher performing students. The results provide new insights into the help-seeking process and suggestions for instructors when allocating time and classroom resources. Additionally, the study illustrates the need for continual refinement of a help-seeking source classification system. © 2015 The British Psychological Society.

    During the early development of remote systems for processing and examining fuel and materials from nuclear reactors, the facility designer and operator worked closely together to meet the challenges of this new field. Numerous challenges still face the nuclear remote systems engineer, e.g., the development of systems that reduce the exposure of workers, the need for advances in basic technology, and the development of cost-effective facilities. The solution to these and other challenges can be accelerated by an expanded program of information exchange, an aggressive development program, and improved project management procedures

    This article conceptualizes the energy problems facing society from a global governance perspective. It argues that a notion of 'global energy governance,' taken to mean international collective action efforts undertaken to manage and distribute energy resources and provide energy services, offers a meaningful and useful framework for assessing energy-related challenges. The article begins by exploring the concepts of governance, global governance, and global energy governance. It then examines some of the existing institutions in place to establish and carry out rules and norms governing global energy problems and describes the range of institutional design options available to policymakers. It briefly traces the role of a selection of these institutions, from inter-governmental organizations to summit processes to multilateral development banks to global action networks, in responding to energy issues, and points out their strengths and weaknesses. The article concludes by analyzing how the various approaches to global governance differ in their applicability to addressing the conundrums of global energy problems. (author)

    The present study examined both within- and between-person associations between adolescents' time use (technology-based activities and face-to-face interactions with friends and family) and sleep behaviors. We also assessed whether age moderated associations between adolescents' time use with friends and family and sleep. Adolescents wore an actigraph monitor and completed brief evening surveys daily for 3 consecutive days. Adolescents (N=71; mean age=14.50 years old, SD=1.84; 43.7% female) were recruited from 3 public high schools in the Midwest. We assessed 8 technology-based activities (eg, texting, working on a computer), as well as time spent engaged in face-to-face interactions with friends and family, via questions on adolescents' evening surveys. Actigraph monitors assessed 3 sleep behaviors: sleep latency, sleep hours, and sleep efficiency. Hierarchical linear models indicated that texting and working on the computer were associated with shorter sleep, whereas time spent talking on the phone predicted longer sleep. Time spent with friends predicted shorter sleep latencies, while family time predicted longer sleep latencies. Age moderated the association between time spent with friends and sleep efficiency, as well as between family time and sleep efficiency. Specifically, longer time spent interacting with friends was associated with higher sleep efficiency but only among younger adolescents. Furthermore, longer family time was associated with higher sleep efficiency but only for older adolescents. Findings are discussed in terms of the importance of regulating adolescents' technology use and improving opportunities for face-to-face interactions with friends, particularly for younger adolescents.

    Full Text Available This paper identifies and discusses the benefits, threats, and vulnerabilities related to the digital revolution. It aims to motivate research and its funding regarding digital threats and vulnerabilities related, in particular, to anticipating unintended, undesirable rebound effects, tipping points, critically fast evolutionary change rates, trade-offs, etc. A brief analysis of the history of the mind and technology reveals slow technological development over tens of thousands of years (including the invention of a place-value digital number system. Then, a small series of groundbreaking ideas (e.g., binary logic, Shannon’s symbolic analysis of relay and switching circuits, architectures of computing enabled the industry-driven invention of programmable computing machines. Ultimately, the mastery of electron and semiconductor physics allowed for economical and seemingly unlimited storage capacity that made digital tools available to all domains of society. Based on the historical analysis, a coupled human-environment systems perspective (that includes a hierarchy assumption ranging from the human cell to the human species enables the identification of several potential challenges to society and science. First, digital nano-engineering promotes genetic modifications (i.e., directed evolution, and synthetic biology enables a new level of the appropriation of nature. The understanding of cell-based biocomputers may call for new forms of logic. These and other challenges require thorough sustainability research in order to anticipate major changes on all levels of human systems. Second, the human individual is exposed to new forms of vulnerability. In particular, the potential epigenetic effects resulting from the excessive use of digital information of historically unknown speed, density, and contents and the loss of (the Western common-law right to privacy resulting from big data (whose ownership is often unknown should become subjects of

    For the LHC to provide particle physics with proton-proton collisions at the centre of mass energy of 14 TeV with a luminosity of 1034 cm-2s-1, the machine will operate with high-field dipole magnets using NbTi superconductors cooled to below the lambda point of helium. In order to reach design performance, the LHC requires both, the use of existing technologies pushed to the limits as well as the application of novel technologies. The construction follows a decade of intensive R&D and technical validation of major collider sub-systems. The first lecture will focus on the required LHC performance, and on the implications on the technologies. In the following lectures several examples for LHC technologies will be discussed: the superconducting magnets to deflect and focus the beams, the cryogenics to cool the magnets to a temperature below the lambda point of helium along most of the LHC circumference, the powering system supplying about 7000 magnets connected in 1700 electrical circuits with a total curr...

  9. A personal perspective on challenges that face women scientists

    Science.gov (United States)

    Cashman, Katharine

    2016-04-01

    Gender equality has been a topic of discussion throughout my long (now three decade) career. This alone illustrates the complex nature of the issue, and the lack of a simple solution, particularly as many of the daily challenges that women face are institution or discipline-specific. For this reason, I will summarize some of the issues that appear to me to be more general, and therefore ones that may have general solutions. The first and foremost relates to demands on women's time. One way that academic institutions have sought to overcome gender bias has been to require that every university committee have a female member; in departments, schools and faculties where women represent a minority, this necessarily means that women shoulder an inequitable share of the service duties. I have experienced this myself, seen it in promotion files at all levels, and observed it with regard to my female colleagues. Clearly time spent doing service is time not spent doing science. There is also an easy solution to this problem, which is to re-think the underlying assumption that men are necessarily gender-biased if they don't have a woman sitting in the room! Additional time demands can come from informal mentoring of both students and younger colleagues, particularly in cases where senior male colleagues are viewed as too important, or too intimidating, to be consulted on personal issues. Although I suspect that this problem may also be widespread, it is more difficult to quantify, and is therefore more difficult to factor into time allotments of departmental duties. A final thought relates to hiring practices. I have now worked in both the US and UK educational systems, which have very different interview and hiring protocols. I will review both, highlighting components that I think are most likely to promote equitable hiring practices.

  10. Representative Delay Measurements (RDM: Facing the Challenge of Modern Networks

    Directory of Open Access Journals (Sweden)

    Joachim Fabini

    2015-02-01

    Full Text Available Network access technologies have evolved significantly in the last years. They deploy novel mechanisms like reactive capacity allocation and time-slotted operation to optimize overall network capacity. From a single node's perspective, such optimizations decrease network determinism and measurement repeatability. Evolving application fields like machine to machine (M2M communications or real-time gaming often have strict real-time requirements to operate correctly. Highly accurate delay measurements are necessary to monitor network compliance with application demands or to detect deviations of normal network behavior, which may be caused by network failures, misconfigurations or attacks. This paper analyzes factors that challenge active delay measurements in modern networks. It introduces the Representative Delay Measurement tool (RDM that addresses these factors and proposes solutions that conform to requirements of the recently published RFC7312. Delay measurement results acquired using RDM in live networks confirm that advanced measurement methods can significantly improve the quality of measurement samples by isolating systematic network behavior. The resulting high-quality samples are one prerequisite for accurate statistics that support proper operation of subsequent algorithms and applications.

  11. Challenges Faced in Field Application of Phosphate-Solubilizing Bacteria

    2017-08-01

    The general inaccessibility of soil phosphorous (P) to plants in combination with the depletion of global P reserves provides an incentive for researchers to find sustainable solutions to sustain food security for the ever-increasing world population. Bio-fertilizers based on bacteria and fungi able to solubilize endogenous P in soils have a high potential for increasing nutrient availability in agriculture. However, the inconsistency of bio-fertilizer performance in the field poses a major challenge for farmers. This discrepancy is thought to stem from the complexity of the interactions between crop plants, microbes, and their soil environments, as well as our lack of understanding of the processes involved. For farmers, a clear beneficial effect across different soil types, crop species, environmental conditions, and microbial communities will be required to make it worth to adopt bio-fertilizer technology based on phosphate-solubilizing microbes (PSMs). Here, we attempt to review the current knowledge of the complexity of the P-solubilization mechanisms used by PSMs and how they may be affected by interactions in the field. We also identify possible explanations for the inconsistent performance of P-solubilizing bacteria in the field and ways to solve these obstacles.

    Davis, Sheila P; Davis, Danyetta D

    2010-01-01

    Current trends in higher education in the United States demand that nursing take stock of how it is prepared or being prepared to face challenges and issues impacting on its future. The intense effort made to attract students to pursue advanced training in science and engineering in the United States pales in comparison to the numbers of science and engineering majors produced yearly in international schools. As a result, more and more jobs are being outsourced to international markets. Could international outsourcing become a method of nursing education? Authors submit that to remain competitive, the nursing profession must attract a younger cohort of technologically savvy students and faculty reflective of the growing diverse population in the United States. Additionally, nursing programs in research universities face even more daunting challenges as it relates to mandates for funded research programs of educational units. This article offers suggestions and recommendations for nursing programs in higher education institutions on ways to attract and retain ethnic minorities and of how to harness the power of research to address burgeoning societal health challenges.

    Ongoing technological advances in pediatrics are improving the survival rates among babies born with life-threatening anomalies. For these neonates, surgeries like brain shunts, trachea, gut and heart reconstruction, and organ transplants are replacing palliative care. Although parents and health care professionals alike are celebrating the successes, advancing technology also raises issues for everyone involved. This paper incorporates Dunst and Trivette's Effective Helpgiving framework and the Calgary Family Intervention Model to recommend nursing care that moves beyond life-saving highly technical surgical procedures and responds to the challenges parents face with their children with complex congenital heart disease, for example, who have "beat the odds."

Faced with these developments, some would claim International Humanitarian Law (IHL is outdated. While these technological innovations present new challenges in the application of IHL, it still constitutes a relevant legal framework for armed conflicts and the conduct of hostilities. Indeed, the flexibility of IHL allows it to adapt to contemporary conflicts. Therefore, this shows that the statements about its obsolescence are primarily political in nature.

    2007-01-01

    In the neck or face, there are different causes for subcutaneous emphysema such as injury to the sinuses, the hypopharynx, the laryngotracheal complex, the pulmonary parenchyma, the esophagus or the presence of gas-forming organisms. However, factitious subcutaneous emphysema, a rare cause, must be considered in the differential diagnosis. In this clinical report, we discuss a 20-year-old girl who was under follow-up because of recurrent subcutaneous emphysema of the face and periorbital area. After 2 years of work-ups, including a period of close observation in the intensive care unit, self air injection by syringe was found as the cause of recurrent subcutaneous emphysema of the face, and the patient was labeled as having factitious recurrent subcutaneous emphysema. Therefore, when a patient presents with unexplained recurrent subcutaneous emphysema, one should suspect self-infliction and examine for puncture marks.

    Full Text Available Peaceful life is one of the first wants of human being which are always threatened with war, civil, regional and global conflict, organized crimes, terrorism, etc. Terrorism development generally marks unfavorable environments, social- class inequality, poverty and violence of human rights. Therefore, terrorism is regarded as a new global challenge in the 3rd millennium aiming at human societies. The activities of terrorists not only do not lead to obtaining their rights or political demands but also while diminishing the bases of global peace; they will challenge human rights. Trying to deal with the relationship between religion and terrorism, this research will investigate the effect of subversive and terrorist activities on human rights and will consider the establishment of the ground for peace geography in conflict environments. It seems that, in general, the environments of terrorism development and growth are backward and underdeveloped in terms of politics, economics and culture due to internal problems or external interference, where religious extremists go toward sectarian violence providing the emergence of religious terrorism. Therefore, human rights will always face the danger of violence and damage. زندگی همراه با آرامش و صلح از ابتدائی‌ترین خواسته‌های بشر است که همواره با جنگ، منازعات داخلی، منطقه‌ای و جهانی، جرم‌های سازمان یافته، تروریسم و ... مورد تهدید قرار می‌گیرد. زمینه‌های شکل گیری تروریسم عموماً بیانگر محیط‌های نامساعد، نابرابری‌های اجتماعی‌ـ طبقاتی، فقر و شرایط ناقض حقوق بشر می‌باشد؛ از این روست که تروریسم در هزاره سوم، چالش جدیدی برای جهان محسوب گردیده و جوامع بشری را مورد هدف خود قرار

    Full Text Available Background: Small businesses are an important part of the South African economy, yet they have high rates of failure. Several contributing factors have previously been identified through literature, including regulatory compliance, skills shortages and lack of government support. Globally, there has been an increased interest in smart cities and the variety of services they offer. These technologies were investigated to establish what role, if any, they could play in alleviating the challenges that small businesses face. Aim: Identify the relative impact of each of these challenges on the small-business and the relative value of each of the smart city services in order to determine which services would have the largest impact in addressing the challenges. Method: This research used these factors and identified which challenges had the largest time and financial impact on small businesses and investigated ways in which a variety of smart city services could be leveraged to address these challenges. Using a multi-criteria decision analysis technique, 44 small-business owners participated in the research. Weighted results for the impact of each of the challenges and the value of each of the services were obtained. Results: Through the subsequent analysis of the results, it was found that small businesses face many challenges because of lack of government and entrepreneurial support, as well as widespread corruption. Similarly, the small-business owners identified that educational material, small-business support portals and eGovernment systems would be the most valuable services that a smart city could offer them. Various sources of literature were used to identify these smart city services and link them to the business challenges that they may be able to mitigate. The infrastructural prerequisites for each of the services were also investigated to identify dependencies and potential problems in their deployment. Conclusion: The various

  10. Workshop and conference on Grand Challenges applications and software technology

    Energy Technology Data Exchange (ETDEWEB)

    1993-12-31

    On May 4--7, 1993, nine federal agencies sponsored a four-day meeting on Grand Challenge applications and software technology. The objective was to bring High-Performance Computing and Communications (HPCC) Grand Challenge applications research groups supported under the federal HPCC program together with HPCC software technologists to: discuss multidisciplinary computational science research issues and approaches, identify major technology challenges facing users and providers, and refine software technology requirements for Grand Challenge applications research. The first day and a half focused on applications. Presentations were given by speakers from universities, national laboratories, and government agencies actively involved in Grand Challenge research. Five areas of research were covered: environmental and earth sciences; computational physics; computational biology, chemistry, and materials sciences; computational fluid and plasma dynamics; and applications of artificial intelligence. The next day and a half was spent in working groups in which the applications researchers were joined by software technologists. Nine breakout sessions took place: I/0, Data, and File Systems; Parallel Programming Paradigms; Performance Characterization and Evaluation of Massively Parallel Processing Applications; Program Development Tools; Building Multidisciplinary Applications; Algorithm and Libraries I; Algorithms and Libraries II; Graphics and Visualization; and National HPCC Infrastructure.

  14. THE CHALLENGES POLITICAL LEADERSHIP FACES IN THE MODERN WORLD

    Directory of Open Access Journals (Sweden)

    T. N. Samsonova

    2016-01-01

    Full Text Available Political leadership is a concept central to understanding political processes and outcomes, yet its definition is elusive. The study of political leadership has a long history. Many disciplines have contributed to this study, including history, philosophy, political theory, psychology etc. Leadership is a process in which leaders and followers interact dynamically in a particular situation or context. Leaders must be able to connect with followers to understand their mood and their initiative. There are essential and operational differences between a leader and a manager. Managerial effectiveness is related to an emphasis on rationality and organizational structure. Leadership effectiveness is linked to symbols and culture. The interactive nature of leader-followers-situation can help us better understand the changing nature of the leaderfollower relationship and the increasingly greater complexity of situations leaders and followers face in contemporary world. Good leadership makes a difference, and it can be enhanced through greater awareness of the important factors influencing the leadership process. The changes we are facing in today’s world demand a new breed of political leaders, new forms and mechanisms of leader-follower interaction that provide effective leadership.

  1. Adequately Addressing Pediatric Obesity: Challenges Faced by Primary Care Providers.

    Science.gov (United States)

    Shreve, Marilou; Scott, Allison; Vowell Johnson, Kelly

    2017-07-01

    To assess the challenges primary care providers encounter when providing counseling for pediatric patients identified as obese. A survey assessed the current challenges and barriers to the screening and treatment of pediatric obesity for providers in northwest Arkansas who provide care to families. The survey consisted of 15 Likert scale questions and 4 open-ended questions. Time, resources, comfort, and cultural issues were reported by providers as the biggest barriers in screening and the treatment of pediatric obesity. All providers reported lack of time as a barrier to providing the care needed for obese children. Cultural barriers of both the provider and client were identified as factors, which negatively affect the care and treatment of obese children. Primary care providers continue to experience challenges when addressing pediatric obesity. In this study, a lack of adequate time to address obesity was identified as the most significant current barrier and may likely be tied to physician resources. Although reimbursement for obesity is increasing, the level of reimbursement does not support the time or the resources needed to treat patients. Many providers reported their patients' cultural view of obesity influenced how they counsel their patients. Increasing providers' knowledge concerning differences in how weight is viewed or valued may assist them in the assessment and care of obese pediatric patients. The challenges identified in previous research continue to limit providers when addressing obesity. Although progress has been made regarding knowledge of guidelines, continuing effort is needed to tackle the remaining challenges. This will allow for earlier identification and intervention, resulting in improved outcomes in pediatric obesity.

  7. Expert opinion: the therapeutic challenges faced by statin intolerance.

    Science.gov (United States)

    Patel, Jaideep; Martin, Seth S; Banach, Maciej

    2016-08-01

    Statin intolerance is largely defined by muscle related symptoms, leading to intolerability and cessation. The nocebo effect coupled with the challenges of diagnosing statin myopathy undermines drug adherence that is critical for achieving the benefits of lipid-lowering and cardiovascular risk reduction. A temporal relationship should be made between the initiation of therapy and development of symptoms to aid in diagnosis. The mainstay of treatment is statin cessation or statin dose reduction and evaluation of alternative causes for muscle related symptoms. Most symptoms usually resolve within 2 weeks of discontinuing therapy. The patient can be re-challenged with the same statin at a lower dose or an alternative statin. Non-statin lipid lowering therapies offer an alternative to patients who cannot tolerate statins. We discuss current guideline-focused management of patients with statin intolerance. When initiating statin therapy, attention to risk factors for statin intolerance is strongly recommended. Most patients will tolerate some degree of statin therapy; thus statin re-challenge is advisable. If alternative dosing regimens are not tolerated, non-statin medications are acceptable alternatives. To limit errors in the diagnosis of statin intolerance, improvements in clinician-patient communication about the side effects and benefits of statins should be attempted.

  8. The United Nations in the Face of Current Challenges

    1995-07-01

    Full Text Available As a result of the 50th anniversary of the birth of the United Nations Organization (UN, this article takes a look at the role which this international organization has played on the international stage and sets out the great challenges which this has to confront today, especially since the transformation of the international system from 1988 onwards and the beginning of (what has been called the end of the Cold War. These challenges are the following: peace-keeping and international security in an increasingly complex and unstable world, the promotion and protection of Human Rights throughout the world and the challenge of development.At the same time, the process of institutional reform taken up by the UN in order to make its various organs more efficient and the obtaining of the necessary financial resources and their putting to more efficent use are also discussed. In this context, the reform of the Security Council as well as in the economic and social sector, the financial problem and the changes made in the organization of the Secretariat are also analysed.The article concludes with the positive evaluation that whatever the imperfections of the UN, the world today would be much less safer and just if it did not exist.

  9. Technological and engineering challenges of fusion

    International Nuclear Information System (INIS)

    Maisonnier, David; Hayward, Jim

    2008-01-01

    The current fusion development scenario in Europe assumes the sequential achievement of key milestones. Firstly, the qualification of the DEMO/reactor physics basis in ITER, secondly, the qualification of materials for in-vessel components in IFMIF and, thirdly, the qualification of components and processes in DEMO. Although this scenario is constrained by budgetary considerations, it assumes the resolution of many challenges in physics, technology and engineering. In the first part of the paper, the technological and engineering challenges to be met in order to satisfy the current development scenario will be highlighted. These challenges will be met by an appropriate share of the work between ITER, IFMIF, DEMO and the necessary accompanying programme, which will have to include a number of dedicated facilities (e.g. for the development of H and CD systems). In the second part of the paper, the consequences of a considerable acceleration of the fusion development programme will be discussed. Although most of the technological and engineering challenges identified above will have to be met within a shorter timescale, it is possible to limit the requirements and expectation for a first fusion power plant with respect to those adopted for the current fusion development scenario. However, it must be recognised that such a strategy will inevitably result in increased risk and a reduction in the economy of the plant. (author)

    Shafran, David; Kodish, Eric; Tzakis, Andreas

    2014-07-01

    The success of organ transplantation as a treatment for end-stage organ disease has yielded a series of ethical quandaries originating from the issue of organ shortage. Scarcity of organs for transplantation necessitates formulation of just and fair allocation policies as well as ethically viable solutions to bridging the vast gap between organ supply and demand. The concept of "triage" provides a useful paradigm in which to contextualize the organ shortage issue. This entails subjugating the welfare of the individual patient for the benefit of the wider community as an ethically justified response to the challenge of scarcity.

  16. Challenges to ethics and professionalism facing the contemporary neurologist.

    Science.gov (United States)

    Bernat, James L

    2014-09-30

    Challenges to ethics and professionalism that can harm neurologists and their patients include the commercialization of medicine, poorly designed Medicare regulations, conflicts of interest, physician employment by hospitals, faulty measurement of medical quality care, electronic health records, electronic communications with patients, and the demotion of the role of physician beneficence. These threats can lead to inaccurate medical record-keeping, unnecessary medical care, a decline in the primacy of patients' interests, and damage to the sanctity of the patient-physician relationship. The increasing frequency of physician burnout can be attributed at least partially to unmitigated stresses on practicing physicians, particularly the growing time pressures for patient visits, the mounting daily requirements of documentation, and the increasing burden of time-consuming but unproductive tasks. Recommended correctives include reforming billing documentation regulations, improving electronic health records, designing proper quality indicators integrating physician wellness, and incorporating reasonable physician workflows in the design of accountable care organizations. © 2014 American Academy of Neurology.

  17. Facing Domestic Violence Against Women in Brazil: Advances and Challenges

    Directory of Open Access Journals (Sweden)

    Thiago Pierobom de Avila

    2018-03-01

    Full Text Available This article aims to offer a critical overview of the Brazilian legal framework for confronting domestic violence against women. Intimate partner homicides are epidemic in Brazil: there are four deaths of women per day. In 2006, the Maria da Penha Law (MPL introduced integrated polices and transformed criminal procedures to deal with the complexities of gender violence. Reforms included the establishment of The House of Brazilian Women, women-only police stations, specialised courts, intervention orders, interdisciplinary experts, and perpetrator programs. In 2015, a new law created the crime of femicide, designed to prevent ‘honor killings’ defenses in cases of intimate partner homicide and to avoid impunity. Despite law reform, structuring and articulating the network of services remains a challenge. The MPL led to great social change in Brazil regarding awareness of the violence against women, facilitating a broader discussion about gender equality.

    This book analyses the factors that influence environmental management in the CNPC when operating outside of China, in the outer margins of the world oil system, specifically in Chad, a Least Developed Country. Within a sector marked by the regulations inherited from the Exxon project in Doba (implemented since 2000 with initial World Bank support), the 2007 CNPC Ronier project aims at refining part of the extracted oil and exporting the remainder, most probably through the pipeline built under the Exxon Doba project. The question of the compatibility between the systems of reference and practices in both firms thus arises. Through the prism of social and environmental responsibility, this text analyses the challenges in the interaction between Chinese oil firms, host countries and OCDE-based firms. (authors)

    The miniaturization, sophistication, proliferation, and accessibility of technologies are enabling the capture of more and previously inaccessible phenomena in Parkinson's disease (PD). However, more information has not translated into a greater understanding of disease complexity to satisfy diagnostic and therapeutic needs. Challenges include noncompatible technology platforms, the need for wide-scale and long-term deployment of sensor technology (among vulnerable elderly patients in particular), and the gap between the "big data" acquired with sensitive measurement technologies and their limited clinical application. Major opportunities could be realized if new technologies are developed as part of open-source and/or open-hardware platforms that enable multichannel data capture sensitive to the broad range of motor and nonmotor problems that characterize PD and are adaptable into self-adjusting, individualized treatment delivery systems. The International Parkinson and Movement Disorders Society Task Force on Technology is entrusted to convene engineers, clinicians, researchers, and patients to promote the development of integrated measurement and closed-loop therapeutic systems with high patient adherence that also serve to (1) encourage the adoption of clinico-pathophysiologic phenotyping and early detection of critical disease milestones, (2) enhance the tailoring of symptomatic therapy, (3) improve subgroup targeting of patients for future testing of disease-modifying treatments, and (4) identify objective biomarkers to improve the longitudinal tracking of impairments in clinical care and research.

    2010-11-01

    Women's health is closely linked to a nation's level of development, with the leading causes of death in women in resource-poor nations attributable to preventable causes. Unlike many health problems in rich nations, the cure relies not only on the discovery of new medications or technology but also getting basic services to the people who need them most and addressing underlying injustice. In order to do this, political will and financial resources must be dedicated to developing and evaluating a scaleable approach to strengthen health systems, support community-based programs, and promote widespread campaigns to address gender inequality, including promoting girls' education. The Millennium Development Goals (MDGs) have highlighted the importance of addressing maternal health and promoting gender equality for the overall development strategy of a nation. We must capitalize on the momentum created by this and other international campaigns and continue to advocate for comprehensive strategies to improve global women's health.

  3. The challenges facing the European Union Centres of Excellence

    International Nuclear Information System (INIS)

    Dupre, Bruno; )

    2012-10-01

    On 19 April 2012, the United Nation Security Council congratulated the European Union for its initiative on centres of excellence in the nuclear, radiological, biological, and chemical fields. The time for glowing reports is over. Three years after its creation, the support of EU Member Sates, the Security Council, the G8, the IEAE, the WHO, the USA, Interpol, the ICRC, has been obtained. Other diplomatic, organisational, and communicative challenges have now arisen regarding implementation. The manifest challenges include: 1/Political exploitation of the centres. Following a recent round table in Algiers, the Algerian press ran headlines such as 'terrorism, the Malian crisis arrives in Algiers' CBRN centres of excellence' and 'Bouteflika, the centres of excellence slight'. 2/Communication errors. A unanimously approved expert in South East Asia became a persona non grata over the last six months despite not making any fundamental mistake, aside from his inability to evaluate the degree of a country's sensitivity and pride. The countries in the region went so far as to threaten to pull out of the Manila centre as a result of this ultimately minor error in communication. 3/The scope of the centres' role complicates the grasp of its objectives. To date, the focus has essentially been on non-proliferation and the fight against CBRN terrorism, under the well-established theme of Resolution 1540. The shift of CBRN focus, at the behest of certain regions, on to real natural risks (pandemics) or industrial risks (protection of crucial infrastructure following an earthquake, flooding, or a tsunami) fundamentally changes the teams' make-up and the mobilization of resources. The emergency services culture is different to that of nonproliferation. However, they both very much address CBRN risks and threats. 4/The limits of the 'bottom-up' approach.

    Full Text Available The search for electroceramic materials with enhanced ferro-pyro-piezoelectric properties and revealing the perovskite type structure has been the objective of a significant number of manuscripts reported in the literature. This has been usually carried out by proposing the synthesis and processing of new compounds and solid solution series. In this work, several methods to obtain ferro-pyro-piezoelectric families of materials featuring the well-known ABO3 perovskite structure (or related such as BaTiO3, Ba1–xCaxTi1–yZryO3, (Bi0.5Na0.5TiO3, (K0.5Na0.5NbO3 and their solid solutions with different cations either in the A or B positions, are presented. For this kind of materials, the challenge for obtaining a single phase compound with a specific grain size and morphology and, most importantly, with the adequate stoichiometry, will also be discussed. The results reviewed herein will be discussed in terms of the tendency of working with softer conditions, i.e., lower temperature and shorter reaction times, also referred to as soft-chemistry.

Abnormal anxiety levels are found in up to 40% of patients with IBD. Anxiety symptoms are often related to flares of IBD but may persist in times of remission. Detection of anxiety disorder (AD in patients with IBD can be challenging. Patients with anxiety may also exhibit symptoms in keeping with functional gastrointestinal disorders (FGID. Evidence for the effectiveness of pharmacological and psychological therapies for anxiety stems from patients without IBD. Studies in patients with IBD have either been small or shown negative results. In light of this, a combined approach involving IBD physicians to improve disease control and psychologists or psychiatrists to treat anxiety is advised. This review examines the evidence of anxiety issues in IBD with a focus on extent of the problem, risk factors for anxiety, and the effectiveness of interventions.

    Although the outlook for most segments of the contract drilling business is now more optimistic than in the past decade, the increased activity has brought several problems: the availability of fully trained crews, the need for new capital, and the limited number of quality drillstrings. These problems will grow in importance if natural gas deliverability begins to decline visibly and once the scramble to correct this decline begins. As the drilling recovery unfolds, the most important lesson to remember, based on worldwide activity in the past year, is how rapidly conditions can change and how quickly excess capacity can turn into chronic shortages. The various segments of the world wide contract drilling industry's prospects have changed dramatically during the past 12 months, and oddly, some market sectors have improved while others have become worse. These quick changes highlight the unpredictable and volatile nature of the markets for contract drilling and other services needed to drill and complete oil and gas wells. The paper describes the business of well drilling onshore and offshore in the US, drilling activities in Canada, international markets, capacity, the supplies of natural gas, Gulf of Mexico activities, drill pipe shortages, manpower shortages, and challenges offshore

    2014-12-01

    We are overwhelmed by warnings about inevitable geophysical and human problems. Earth is beset by escalating, manmade, environmental crises and our exploding population will eventually lack water, food and vital materials. This suggests, together with increasing poverty, deepening social unrest and advanced techniques for mass killing, that civilization will break down long before atmospheric CO2 or resistant microbes become catastrophic. Despite intensive searching, life has not been found in space, even though thousands of planets have been found and life there may be as problematic and unpredictable as on Earth. The human brain is already a 'universe', with 85 billion neurons and a hundred trillion synapses, more than the stars in our galaxy. Understanding consciousness, the brain, its aging and pathologies, and eliminating the propensity for human aggression are urgent challenges. During 1958-2012, NASA spent $800 billion. In contrast, the annual cost of brain disease in the U.S. is $600 billion, more than cardiovascular disease and cancer combined. We suggest that a massive switching of financial and human resources is required to explore the full potential of the human brain. Visiting Mars can wait. We further propose a novel Two-Brain Hypothesis: the animal 'brain' evolved as two fundamentally different though interdependent, complementary organs: one electroionic (tangible, known and accessible), and the other, electromagnetic (intangible and difficult to access)--a relatively independent, stable, structured and functional 3D compendium of variously induced interacting EM fields.

    2015-07-01

    Teaching of manufacturing courses for undergraduate engineering students has become a challenge due to industrial globalisation coupled with influx of new innovations, technologies, customer-driven products. This paper discusses development of a modern manufacturing course taught concurrently in three institutions where students collaborate in executing various projects. Lectures are developed to contain materials featuring advanced manufacturing technologies, R&D trends in manufacturing. Pre- and post-surveys were conducted by an external evaluator to assess the impact of the course on increase in student's knowledge of manufacturing; increase students' preparedness and confidence in effective communication and; increase students' interest in pursuing additional academic studies and/or a career path in manufacturing and high technology. The surveyed data indicate that the students perceived significant gains in manufacturing knowledge and preparedness in effective communication. The study also shows that implementation of a collaborative course within multiple institutions requires a robust and collective communication platform.

    2005-01-01

    During the 20th century, the iron ore mining industries of Canada and the United States passed through several periods of transformation. The beginning of the 21st century has seen yet another period of transformation, with the economic failure of a number of steel companies, the acquisition of their facilities by more viable steelmakers, and the consolidation of control within the North American iron ore industry. Changes in Canadian and United States iron ore production and the market control structure involved are analysed. The consolidation of ownership, formation of foreign joint ventures within Nordi America, planned divestitures of upstream activities by steelmakers, and industry changes made to ensure availability of feedstocks will be reviewed. The ttaditional isolation of the Canadian and United States iron ore operations and their strong linkage to downstream steel production will be discussed in the context of a changing global economy. Management-labour conflicts that have taken place and agreements made during 2000 through 2004 will be discussed in the context of the economic environment leading up to these agreements. Cooperative agreements between competing Canadian and United States companies to resolve client needs in processing and blending will be examined. A joint industry-government project designed to use new technology to produce direct reduced iron nuggets of 96 - 98 per cent iron content using non-coking coals will also be assessed. Changes in iron ore transportation methods, ownership and infrastructure will be reviewed for both rail and inland waterway transport between Canadian and United States companies. A brief analysis of social and environmental issues relating to sustainable development of the Canadian-United States iron ore industry will be included.

    Middle income countries like those in the Caribbean can feel proud of their achievements in health care. There has been a dramatic fall-off in infant mortality and crude mortality rates along with significant improvements in life expectancy at birth. However, these countries now find themselves grappling with the burden of chronic non-communicable diseases such as heart disease, stroke, hypertension, diabetes mellitus and cancer. There are good data to support the view that some of these diseases, in particular diabetes mellitus, have assumed epidemic proportions and there is concern that this fact may have been missed by many because of the surreptitious onset, as is the nature of the chronic diseases. The impact of this epidemic may have suffered because of the higher profile of more topical issues like HIV/AIDS even though the former makes a larger contribution to morbidity and mortality statistics. It is now obvious that despite the impact of other factors, lifestyle changes are the major contributors to the epidemic. In populations of similar genetic stock, living in significantly different socio-economic circumstances, the impact of increased dietary salt, increasing obesity and decreased physical activity on the prevalence of hypertension, diabetes mellitus and lipid disorders is unequivocal. Data from the developed world, which has already been through this epidemic of chronic diseases, have shown that increasing technological advances in medical care is an inefficient way to respond to the situation. A multi-sectoral approach is required to tackle this epidemic, including the provision of incentives for healthy eating and widespread opportunities for increased exercise and other physical activities. Continued research into the evolution of the epidemic, including reliable estimates via surveillance methods is a necessary component of our response. The problems and the solutions are not only the responsibilities of the health officials but must involve

It is coauthored by academic researchers and senior service providers so as to embrace the multidimensional issues impacting on this subject. If lean thinking is to be implemented in relation to health visiting, it is important to understand how it is likely to be viewed by practitioners and line managers in settings where it is used. In order to contextualize the discussion, an introduction to the roles, systems, and structures of health visiting are provided. The literature on what lean implementation is, what it means, and in particular the application and potential of the approach to primary care and public health services is reviewed. The process and findings from a focus group convened within a large primary care organization in the National Health Service during their lean implementation is reported. The paper concludes that it is important for staff at all levels to see a clear link between strategic aims and objectives and the planning processes operated by providers and commissioners. It appears that the successful introduction of lean thinking should focus more on productive working and thereby reducing waste. This has the potential to refresh workforce models to ensure that health visiting and other practitioners liberate the use of their specialist knowledge and skills. In a context of enhanced partnership working, the stage is then set for providers to add value to the whole

    2018-03-01

    competitiveness, measured in terms of scientific yield and citations, primarily affects fields where articles and citations are not the traditional outputs, such as the humanities and social sciences in general and planning-related disciplines in particular. When discussing planning, it has to be stressed out that research has a merely societal value and is not aimed at developing products that can foster economic growth or delivering scientific articles that profoundly change the theoretical perspectives. Simply put, research in planning aims at increasing the safety and welfare of people. As a consequence, planning research topics have shifted from providing scientific grounds to regional development policies, to addressing research quality and social responsibility or producing research guidelines. This article looks at the particular case of Romanian planning research based on SCImago data, in an attempt to assess whether this field is able to meet these global challenges, especially after the consistent, albeit uneven, in terms of goal and pace, application of new research policies designed after joining the European Union, which were aimed at increasing its article output and its international visibility. The findings indicate that the numerical growth of articles and publications is spectacular in Romania for most fields, and even more so within the humanities, the social sciences and planning. However, the question remains whether this impressive growth is supported by an increase in quality. We have therefore left aside matters such as the globalization of authors, topics or citations. These aspects require a more in-depth research effort.

    The ITER divertor vertical target has to sustain heat fluxes up to 20 MW m -2 . The concept developed for this plasma facing component working at steady state is based on carbon fibre composite armour for the lower straight part and tungsten for the curved upper part. The main challenges involved in the use of such components include the removal of the high heat fluxes deposited and mechanically and thermally joining the armour to the metallic heat sink, despite the mismatch in the thermal expansions. Two solutions based on the use of a CuCrZr hardened copper alloy and an active metal casting (AMC (registered) ) process were investigated during the ITER EDA phase: the first one called 'flat tile geometry' was mainly developed for the Tore Supra pumped limiter, the second one called 'monoblock geometry' was developed by the EU Participating Team for the ITER project. This paper presents a review of these two solutions and analyses their assets and drawbacks: pressure drop, critical heat flux, surface temperature and expected behaviour during operation, risks during the manufacture, control of the armour defects during the manufacture and at the reception, and the possibility of repairing defective tiles

    McGowan, Kevin B; Stiegman, Glenn

    2013-01-01

    In the United States, few Food and Drug Administration (FDA)-approved options exist for the treatment of focal cartilage and osteochondral lesions. Developers of products for cartilage repair face many challenges to obtain marketing approval from the FDA. The objective of this review is to discuss the necessary steps for FDA application and approval for a new cartilage repair product. FDA Guidance Documents, FDA Panel Meetings, scientific organization recommendations, and clinicaltrials.gov were reviewed to demonstrate the current thinking of FDA and the scientific community on the regulatory process for cartilage repair therapies. Cartilage repair therapies can receive market approval from FDA as medical devices, drugs, or biologics, and the specific classification of product can affect the nonclinical, clinical, and regulatory strategy to bring the product to market. Recent FDA guidance gives an outline of the required elements to bring a cartilage repair product to market, although these standards are often very general. As a result, companies have to carefully craft their study patient population, comparator group, and clinical endpoint to best showcase their product's attributes. In addition, regulatory strategy and manufacturing process validation need to be considered early in the clinical study process to allow for timely product approval following the completion of clinical study. Although the path to regulatory approval for a cartilage repair therapy is challenging and time-consuming, proper clinical trial planning and attention to the details can eventually save companies time and money by bringing a product to the market in the most expeditious process possible.

    The paper deals with the abandonment of offshore wells. Decommissioning of offshore installations is a complex multi-disciplined issue, which raises a number of technical, organisational and environmental challenges. The success of a planned decommissioning operation depends on the development of a clear understanding of the complex blend of drivers which control the decommissioning process and their inter-relationship. Due to the complexity of the inter-relationship between the primary drivers one cannot separate the technological, organisational and environmental issues raised by the decommissioning of offshore installations. The optimal solution will be a compromise between all the decommissioning drivers mentioned in this paper. 5 figs., 3 tabs

    There is growing interest in, and hopes for, nuclear disarmament in governments and nongovernmental organizations (NGOs) around the world. If a nuclear-weapon-free world is to be achievable, verification and compliance will be critical. VerifYing disarmament would have unprecedented scientific, technological and political challenges. Verification would have to address warheads, components, materials, testing, facilities, delivery capabilities, virtual capabilities from existing or shutdown nuclear weapon and existing nuclear energy programs and material and weapon production and related capabilities. Moreover, it would likely have far more stringent requirements. The verification of dismantlement or elimination of nuclear warheads and components is widely recognized as the most pressing problem. There has been considerable research and development done in the United States and elsewhere on warhead and dismantlement transparency and verification since the early 1990s. However, we do not today know how to verifY low numbers or zero. We need to develop the needed verification tools and systems approaches that would allow us to meet this complex set of challenges. There is a real opportunity to explore verification options and, given any realistic time frame for disarmament, there is considerable scope to invest resources at the national and international levels to undertake research, development and demonstrations in an effort to address the anticipated and perhaps unanticipated verification challenges of disarmament now andfor the next decades. Cooperative approaches have the greatest possibility for success.

    Face-gear drives become the main direction of research for aeronautical drives because of their special advantages. Face-gear machining problems have became to baffle the embedded research for face-gear. The basal coordinate systems of face-gear hobbing were setted up according to the face-gear hobbing theory. The hobbing surface equation of facegear was established by using the equation of pinion tooth surface and matrix for coordinate transform based on the gear geometry and applied theory, then the hobbing tooth surface constrain conditions for dedendum undercutting were analyzed, at the same time, the hobbing nodal points were used to construct the three-dimensional basal worm model of face-gear hob by recurring to the three-dimensional software. Furthermore, the special hob for face-gear machining was designed and manufactured. The exact assembly and machining simulation were finished by using the program development software VC++6.0 and the UG customization function in the light of the face-gear hobbing theory. It validates the hob correctness and gets the gear hobbing program. According to the result of machining simulation, facegear numerical control(NC) hob machining was realized in the four-axis NC machine tool. It improves the cutting efficiency and establishs the base for face-gear grinding.

    The aims of this research were to determine extra-organisational challenges (e.g. market competition, governing policies) faced by community pharmacies in Sarawak, the coping strategies employed to deal with these challenges and explore potential legislative changes that can attenuate the intensity of these challenges. Survey questionnaires (n = 184) were posted to all eligible community pharmacies in Sarawak, Malaysia. The questionnaire included sections on participants' demographic data, extra-organisational challenges faced, coping strategies employed and proposals to improve community pharmacy legislations. Items were constructed based on the findings of a prior qualitative research supplemented with relevant literature about these issues. High levels of homogeneity in responses were recorded on various extra-organisational challenges faced, particularly those economy-oriented. Strategic changes to counter these challenges were focused on pricing and product stocked, rather than services provision. Highly rated strategies included increasing discounts for customers (n = 54; 68%) and finding cheaper suppliers (n = 70; 88%). Legislative changes proposed that might increase their share of the pharmaceutical market were strongly supported by respondents, particularly about making it compulsory for general practitioners to provide patients the option to have their medicines dispensed in community pharmacies (n = 72; 90%). Current legislative conditions and Malaysian consumer mindset may have constrained the strategic choices of community pharmacies to deal with the strong extra-organisational challenges. A long-term multipronged approach to address these issues and increased involvement of community pharmacists themselves in this agenda are required to influence practice change. © 2018 Royal Pharmaceutical Society.

    While our Y2K worries about old computers “retiring” at midnight captured the television and news media attention, a more significant “old age” phenomenon snuck onto the scene with hardly a headline: the dawn of the age of the aged. 1 The over burdened health care system will face a worldwide wave of retirees who will live longer, cost more to treat, and demand new goods and services to help them stay healthy, active, and independent. Research in persuasive technologies and the associated usage of a computing system, device, or application intentionally designed to change a person's attitude or behavior in a predetermined way is showing the potential to assist in improving healthy living, reduce the costs on the health care system, and allow the aged to maintain a more independent life. This article gives a deeper insight into the evolution of persuasive technologies and presents a framework that can guide a researcher or practitioner in comprehending more effectively the work being done in this novel research field. It also provides categories of domains within health care in which these technologies are used and surveys exemplars from published literature. The article's goal is to provide greater understanding by addressing the challenges that lie ahead for all key stakeholders that design and/or use persuasive technologies in health care.

    To explore the challenges facing pharmacovigilance in Saudi Arabia and formulate recommendations to improve it from the perspective of healthcare professionals in Saudi Arabia. This was a qualitative study of 4 focus group discussions with pharmacists, physicians, and academicians held under the auspices of the King Saud University School of Pharmacy and the Center for Medicine in the Public Interest, Riyadh, Saudi Arabia. A total of 29 eligible healthcare professionals were invited to participate in the discussion. The predefined themes of the study were the current practice and major challenges facing pharmacovigilance in regulatory bodies, hospitals, the community, and academia, as well as recommendations to improve pharmacovigilance practice.  Of the 29 participants invited, 27 attended the discussion. Challenges facing regulatory bodies included complicated adverse drug reactions (ADR) reporting forms, lack of feedback on ADRs submitted to the Saudi Food and Drug Authority, lack of decisions from the local authority to withdraw medications, and lack of data on pharmacovigilance. The challenges to pharmacovigilance in hospitals included the lack of knowledge of the significance of ADR reporting, workload, blaming culture, and lack of collaboration between regulatory bodies and hospitals. However, challenges facing pharmaceutical industries included the lack of drug manufacturers in Saudi Arabia and lack of interest in pharmacovigilance. Recommendations to improve pharmacovigilance included the need for communication, stronger regulatory requirements, the need for research, the need for unified ADRs reporting, and continuous education and training.  The study has identified the challenges facing pharmacovigilance in Saudi Arabia and made certain recommendations to overcome them. These recommendations might be helpful for regulatory bodies to enhance spontaneous reporting and promote pharmacovigilance.

    Translating research into practice, especially the implementation of digital health technologies in routine care, is increasingly important. Yet, there are few studies examining the challenges of implementing patient-facing digital technologies in health care settings. The aim of this study was to report challenges experienced when implementing mobile apps for patients to support their postsurgical rehabilitation in an orthopedic setting. A mobile app was tailored to the needs of patients undergoing rotator cuff repair. A 30-min usability session and a 12-week feasibility study were conducted with patients to evaluate the app in routine care. Implementation records (observation reports, issues log, and email correspondence) explored factors that hindered or facilitated patient acceptance. Interviews with clinicians explored factors that influenced app integration in routine care. Participant completion was low (47%, 9/19). Factors that affected patient acceptance included digital literacy, health status, information technology (IT) infrastructure at home, privacy concerns, time limitations, the role of a caregiver, inconsistencies in instruction received from clinicians and the app, and app advice not reflective of patient progress over time. Factors that negatively influenced app integration in routine care included competing demands among clinicians, IT infrastructure in health care settings, identifying the right time to introduce the app to patients, user interface complexity for older patients, lack of coordination among multidisciplinary clinicians, and technical issues with app installation. Three insights were identified for mobile app implementation in routine care: (1) apps for patients need to reflect their journey over time and in particular, postoperative apps ought to be introduced as part of preoperative care with opportunities for patients to learn and adopt the app during their postoperative journey; (2) strategies to address digital literacy

    Industrial fermentation processes are increasingly popular, and are considered an important technological asset for reducing our dependence on chemicals and products produced from fossil fuels. However, despite their increasing popularity, fermentation processes have not yet reached the same maturity as traditional chemical processes, particularly when it comes to using engineering tools such as mathematical models and optimization techniques. This perspective starts with a brief overview of these engineering tools. However, the main focus is on a description of some of the most important engineering challenges: scaling up and scaling down fermentation processes, the influence of morphology on broth rheology and mass transfer, and establishing novel sensors to measure and control insightful process parameters. The greatest emphasis is on the challenges posed by filamentous fungi, because of their wide applications as cell factories and therefore their relevance in a White Biotechnology context. Computational fluid dynamics (CFD) is introduced as a promising tool that can be used to support the scaling up and scaling down of bioreactors, and for studying mixing and the potential occurrence of gradients in a tank.

    2004-01-01

    Radiation detection technologies are an important tool in the prevention of proliferation. A variety of new developments have enabled enhanced performance in terms of energy resolution, spatial resolution, predictive modeling and simulation, active interrogation, and ease of operation and deployment in the field. For example, various gamma ray imaging approaches are being explored to combine spatial resolution with background suppression in order to enhance sensitivity at reasonable standoff distances and acquisition times. New materials and approaches are being developed in order to provide adequate energy resolution in field use without the necessity for liquid nitrogen. Finally, different detectors combined into distributed networks offer promise for detection and tracking of radioactive materials. As the world moves into the 21st century, the possibility of greater reliance on nuclear energy will impose additional technical requirements to prevent proliferation. In addition to proliferation resistant reactors, a careful examination of the various possible fuel cycles from cradle to grave will provide additional technical and nonproliferation challenges in the areas of conversion, enrichment, transportation, recycling and waste disposal. Radiation detection technology and information management have a prominent role in any future global regime for nonproliferation beyond the current Advanced Protocol. This work was performed under the auspices of the U.S. Department of Energy by University of California, Lawrence Livermore National Laboratory under contract No. W-7405-Eng-48. (author)

    This historic-sociologic study aims to analyse the challenges faced by the Brazilian Expeditionary Force's Air Transportation Nurses of the Army with the Theatre of Operations on the course of World War II. The primary source was comprised of a photograph from this time period and oral testimonies of those who participated in the conflict. Ideas by sociologist Pierre Bourdieu support the discussion. Results suggest that Brazilian nurses were challenged to transport the wounded without medical advice. We conclude that the challenge to fulfill the task imposed, which led to independent decision-making, gave confidence and autonomy to the ones already responsible for the transportation of the wounded.

    Securing energy demand for next generations is one of the most challenges aspects facing any sustained development plans, due to the growing electric energy demand and Egypt as a country of limited fossil fuel resources has to diversify its energy portfolio by utilization of its renewable energy resources, mainly wind due to its economic potential and solar as proved by Egypt's wind and solar atlases. In the year 2009/2010, the total installed capacity in Egypt was 24726 MW with electricity generation 139,000 GWh, of which 89 % was delivered by thermal plants and about 10% from Hydro power with total installed 2800 MW and electricity generated is about 12863 GWh and 1% from Wind energy with total installed 550 MW and electricity generated 1542 GWh. In the solar energy field, the first solar thermal power plant of 140 MW with a solar share of 20 MW using parabolic trough technology was started the initial work since the 1 st of July with estimated total energy generated of 852GWh/year. Recently, Egypt has adopted an ambitious plan to cover 20% of the generated electricity by renewable energy by 2020, including a 12% contribution from wind energy, translating more than 7200 MW grid-connected wind farms. Such plan gives a room enough to the private investment to play the major role in realizing this goal. The plan includes also a 100 MW Solar thermal energy CSP with parabolic trough technology in Kom Ombo city, and also two PV plants in Hurgada and Kom Ombo with a total installed capacity 20 MW each. Due to the high investment cost of solar energy technologies, still limited in spread all over the world on the other hand wind energy has an economic potential and becomes a commercial technology but the future potential for solar energy due to the limited land for wind energy. Current study will evaluate the Egyptian strategy for renewable energy up to 2020 and find how much the planned projects from the Egyptian government will fulfill its target, the economic study

  7. Turning Technologies into Businesses- The Challenge for the Technical Entrepreneur

    2000-03-01

    Over the past twenty-five years, new businesses based on innovative technology have been the driving force for the US economy. Due to the abundance of early-stage capital, each year, thousands of scientists and engineers receive support to start new, technology-based businesses. However, the transition from technologist to entrepreneur is often difficult. It requires a shift in emphasis from a technology focus to a market focus. We shall discuss the challenges facing the technical entrepreneur in launching a new enterprise, and a variety of resources that are available to help the entrepreneur succeed. Many technologists fall victim to the myth that if you ``build a better mousetrap, the world will beat a path to your door." To be sure, it is important to base your business on sound technology that offers a clear advantage over current practice, and, if possible, to secure title to the technology, either by obtaining patent protection, or securing an exclusive license. Once that is done, however, the principal concern of the fledgling enterprise is building a business and obtaining the financial resources to enable it to grow. The entrepreneur must develop a clear and compelling business model, that can be communicated to a non-technical investor in a few minutes. This requires a mode of thinking and expression quite different from that commonly used in engineering or scientific discussions. Fortunately, abundant resources are available to help the technologist become a successful entrepreneur. We shall discuss the kinds of assistance that are generally available through local and national programs, and give specific examples based on the activities of the Bay Area Regional Technology Alliance in northern California.

    Full Text Available Big Data has gained much attention from the academia and the IT industry. In the digital and computing world, information is generated and collected at a rate that rapidly exceeds the boundary range. Currently, over 2 billion people worldwide are connected to the Internet, and over 5 billion individuals own mobile phones. By 2020, 50 billion devices are expected to be connected to the Internet. At this point, predicted data production will be 44 times greater than that in 2009. As information is transferred and shared at light speed on optic fiber and wireless networks, the volume of data and the speed of market growth increase. However, the fast growth rate of such large data generates numerous challenges, such as the rapid growth of data, transfer speed, diverse data, and security. Nonetheless, Big Data is still in its infancy stage, and the domain has not been reviewed in general. Hence, this study comprehensively surveys and classifies the various attributes of Big Data, including its nature, definitions, rapid growth rate, volume, management, analysis, and security. This study also proposes a data life cycle that uses the technologies and terminologies of Big Data. Future research directions in this field are determined based on opportunities and several open issues in Big Data domination. These research directions facilitate the exploration of the domain and the development of optimal techniques to address Big Data.

    In our paper, we review some of the key challenges associated with the Ni silicidation process in the most recent CMOS technologies. The introduction of new materials (e.g.SiGe), and of non-planar architectures bring some important changes that require fundamental investigation from a material engineering perspective. Following a discussion of the device architecture and silicide evolution through the last CMOS generations, we focus our study on a very peculiar defect, termed NiSi-Fangs. We describe a mechanism for the defect formation, and present a detailed material analysis that supports this mechanism. We highlight some of the possible metal enrichment processes of the nickel monosilicide such as oxidation or various RIE (Reactive Ion Etching) plasma process, leading to a metal source available for defect formation. Furthermore, we investigate the NiSi formation and re-formation silicidation differences between Si and SiGe materials, and between (1 0 0) and (1 1 1) orientations. Finally, we show that the thermal budgets post silicidation can lead to the formation of NiSi-Fangs if the structure and the processes are not optimized. Beyond the understanding of the defect and the discussion on the engineering solutions used to prevent its formation, the interest of this investigation also lies in the fundamental learning within the Ni–Pt–Si–Ge system and some additional perspective on Ni-based contacts to advanced microelectronic devices.

    Grünberg, Jose

    2010-03-01

    Dramatic demographic changes longevity and medical progress helped create a new population made up of the survivors of previously fatal diseases. These trends pose new major social and economic challenges that should be accounted for in health policy making. This paper discusses the similarities between the specialties of pediatrics and geriatrics, especially in the realm of patient care. Children and the elderly share a limited autonomy and dependence on the human environment (i.e., willing and able caregiving persons) due to age or disease. The long-term care of dependent patients (DP) requires caregiving persons who share with dependent persons the risk of losing autonomy, facing burnout, family disruption, and interference with work and educational activities. Families with DPs may face potential losses of income because both patients and caregivers are partially or completely unable to work, the former for medical reasons and the latter due to the new demands on their time and energy. Additionally, new expenses have to be met because while direct medical expenses might be covered by insurance or the State, other expenses have to be financed by the family, such as co-payments for medicines, new water or electricity home installations, and transport and eventual hotel costs if they have to stay overnight near a hospital outside of their town. The main objectives of long-term care should be to maximize patients' independence and prevent their physical and psychological deterioration while minimizing the social, economic and personal costs to caregivers. To achieve these goals, one needs a holistic approach, a multidisciplinary professional team (doctors, nurses, social workers, nutritionists and psychologists) and auxiliary staff (secretaries, electricians, administrators, messengers, cleaning staff, doormen, nursing aids and coordinators of medical appointments and medical procedures). Optimal management of DPs on chronic treatments such as chronic dialysis

    Parenting children with learning disabilities requires a high level of knowledge and access to resources, information and services. In developing countries, however, these resources and services are not always available. Parents in Namibia, a developing country, therefore face challenges addressing children's learning and other developmental disabilities, including challenges related to preventative and supportive interventions. This research focuses on challenges faced by parents as they parent children with learning disabilities in Opuwo, Namibia. In-depth interviews were conducted with eight parents regarding the challenges they face in parenting their children with learning disabilities. Thematic analysis enabled the researchers to identify, analyse and report on themes that emerged from the qualitative interview data. Analysis of the interviews indicated that some participants had only a vague understanding of learning disabilities, as they did not have access to essential knowledge about this phenomenon. They also lacked an awareness of the availability of programmes, services and policies meant to benefit their children with learning disabilities. Participants voiced that they, their children with learning disabilities and community members have stereotypes and prejudices regarding learning disabilities. In this study, most of the children with learning disabilities were raised by single, unemployed parents who seemed to have access to less support from external sources than married couples parenting children with learning disabilities. These single parents are usually not married and because of lack of financial support from the other parent, the majority of them indicated that they struggle to meet the financial and material needs of their children. The researchers concluded that the participants in this study experience a range of challenges in parenting their children with learning disabilities. The main challenges emanate from financial instability, as

    Full Text Available Web-based lecture technologies (WBLT have gained popularity amongst universities in Australia as a tool for delivering lecture recordings to students in close to real time. This paper reports on a selection of results from a larger research project investigating the impact of WBLT on teaching and learning. Results show that while staff see the advantages for external students, they question the extent to which these advantages apply to internal students. In contrast both cohorts of students were positive about the benefits of the technologies for their learning and they adopted similar strategies for their use. With the help of other technologies, some external students and staff even found WBLT useful for fostering communication between internal and external students. As such, while the traditional boundary between internal and external students seems to remain for some staff, students seem to find the boundary much less clear.

    In 2003, an ICRC-SFD Ponseti program was introduced in southern Vietnam. Additional programs were introduced by the Prosthetics Outreach Foundation and independently by physicians trained at our center. The purpose of this study was to evaluate the impact, progress and challenges facing Ponseti practitioners and patients' family members in Vietnam. In addition, web-conferencing (Ponseti Virtual Forum) for continued medical education in the method was also assessed. Multiple questionnaires were developed to conduct face-to-face practitioner interviews, focus group interviews, and parental interviews. Observation was done at multiple site clinics to determine or confirm additional challenges faced by practitioners. Web conferencing was introduced to sites in Ho Chi Minh City and Da Nang City. The number of clubfoot patients treated with the Ponseti method has increased over time with approximately 1,252 infants treated between 2003 and 2010. Specific challenges were identified relating to communication, networking, distance and transportation, and finances for both practitioners and parents. The PVF was not only found to facilitate rapid, relevant dissemination of medical knowledge--thus increasing physician and patient satisfaction--but it may also be found to act as an interface in which medical culture, insight, and compassion are shared benefiting all virtual forum participants. The identified progress and challenges mirrored that of similar studies done in other countries with several factors affecting progress. Focusing on improving communication channels and networking while working with the ministry of health may improve the facilitation of the Ponseti method in Vietnam. Further implementation and evaluation of the PVF may act as a guide for current and future programs in Vietnam or other countries.

    The marketing and successful distribution of artificial-intelligence-based decision-support systems for nursing face special barriers and challenges. Issues that must be confronted arise particularly from the present culture of the nursing profession as well as the typical organizational structures in which nurses predominantly work.

    Lassi, Zohra S; Salam, Rehana A; Bhutta, Zulfiqar A

    The health challenges faced by young people are more complex than adults and can compromise their full growth and development. Attention must be paid to the health of this age group, yet adolescents and youth remain largely invisible and often disappear from the major global datasets. The aim of this paper is to discuss the global health challenges faced by adolescents and youth, global legislations and guidelines pertaining to this particular age group, recommendations to arrest these challenges, and research priorities. Major direct and indirect global health risks faced by adolescents include early pregnancy and childbirth, femicide, honor killing, female genital mutilation, nutritional habits and choices, social media, and peer pressure. There are no standard legal age cut-offs for adulthood; rather, the age varies for different activities, such as age of consent or the minimum age that young people can legally work, leave school, drive, buy alcohol, marry, be held accountable for criminal action, and make medical decisions. This reflects the fact that the existing systems and structures are focused on either children or adults, with very few investments and interventions directed specifically to young people. Existing legislation and guidelines need transformation to bring about a specific focus on adolescents in the domains of substance use and sexual behaviors, and the capacity for adolescent learning should be exploited through graduated legal and policy frameworks. Sustainable development goals provide an opportunity to target this neglected and vulnerable age group. A multisectoral approach is needed to bring about healthy change and address the challenges faced by adolescents and youth, from modifications at a broader legislative and policy level to ground-level (community-level) implementations.

  5. Challenges facing translational research organizations in China: a qualitative multiple case study

    Science.gov (United States)

    2013-01-01

    Background Translational medicine is attracting much attention worldwide and many translational research organizations (TROs) have been established. In China, translational medicine has developed rapidly, but faces many challenges. This study was aimed at exploring these challenges faced by emerging TROs in China. Method A qualitative, multiple case study approach was used to assess the challenges faced by TROs in China. Data were collected between May and August 2012. Results Eight cases were identified. Overall, four themes that characterized TROs in China emerged from analyses: 1. objectives, organizer, and funding resources, 2. participating partners and research teams, 3. management, and 4. achievements. All TROs had objectives related to translating basic discovery to clinic treatment and cultivating translational researchers. In terms of organizer and funding resources, 7 out of 8 TROs were launched only by universities and/or hospitals, and funded mostly through research grants. As for participating partners and multidisciplinary research teams, all but one of the TROs only involved biomedical research institutions who were interested in translational research, and characterized as clinical research centers; 7 out of 8 TROs involved only researchers from biomedicine and clinical disciplines and none involved disciplines related to education, ethnicity, and sociology, or engaged the community. Current management of the TROs were generally nested within the traditional research management paradigms, and failed to adapt to the tenets of translational research. Half of the TROs were at developmental stages defined as infrastructure construction and recruitment of translational researchers. Conclusions TROs in China face the challenge of attracting sustainable funding sources, widening multidisciplinary cooperation, cultivating multi-disciplinary translational researchers and adapting current research management to translational research. Greater emphasis should

    2017-09-01

    This study explored the food challenges facing people living with HIV/AIDS in Tsholotsho, Zimbabwe. Tsholotsho is a socio-economically disadvantaged, rural district in Zimbabwe and has one of the highest HIV prevalence rates in the country. For this study, face to face in-depth interviews were held with men and women living with HIV/AIDS. The findings of the study indicate that the economic situation in the country coupled with the lack of adequate rainfall has posed challenges to the ability of HIV/AIDS patients to maintain a healthy diet. In addition, there were concerns about the departure of non-government organisations which used to provide them with food parcels. The interviews also reveal that indigenous foods are being replaced by processed foods that are less healthy. Lack of employment opportunities and safety networks were some of the other factors leading them to experience food challenges in their everyday lives particularly in terms of access. As food security and good nutrition are key for maintaining physical and emotional health, the cumulative effects of these factors create a difficult environment to access food.

  13. How inverse solver technologies can support die face development and process planning in the automotive industry

    Science.gov (United States)

    Huhn, Stefan; Peeling, Derek; Burkart, Maximilian

    2017-10-01

    With the availability of die face design tools and incremental solver technologies to provide detailed forming feasibility results in a timely fashion, the use of inverse solver technologies and resulting process improvements during the product development process of stamped parts often is underestimated. This paper presents some applications of inverse technologies that are currently used in the automotive industry to streamline the product development process and greatly increase the quality of a developed process and the resulting product. The first focus is on the so-called target strain technology. Application examples will show how inverse forming analysis can be applied to support the process engineer during the development of a die face geometry for Class `A' panels. The drawing process is greatly affected by the die face design and the process designer has to ensure that the resulting drawn panel will meet specific requirements regarding surface quality and a minimum strain distribution to ensure dent resistance. The target strain technology provides almost immediate feedback to the process engineer during the die face design process if a specific change of the die face design will help to achieve these specific requirements or will be counterproductive. The paper will further show how an optimization of the material flow can be achieved through the use of a newly developed technology called Sculptured Die Face (SDF). The die face generation in SDF is more suited to be used in optimization loops than any other conventional die face design technology based on cross section design. A second focus in this paper is on the use of inverse solver technologies for secondary forming operations. The paper will show how the application of inverse technology can be used to accurately and quickly develop trim lines on simple as well as on complex support geometries.

    Kulintornprasert, Usanee

    Scope and method of study. The purpose of this study is to examine the responses of Thai educators and other stakeholders in each organization. They are facing the challenge of increasing scientific and technological manpower for the future of scientific and technological capabilities in Thailand. A dramaturgy analysis procedure serves as the framework for the study. This framework provides a tool to help comprehend, describe, communicate, and transform the character and process of the remedy of the S&T manpower shortage. Namely, Burke's five elements are useful in this process. The scene is the setting of the performance, which refers to the current situation of Thailand's science and technology capability. The act displays various problems that take place in the setting. The agent means the groups of people who are involved in the S&T manpower development process and their roles to accelerate S&T manpower development strategies. The agency describes the projects that support those strategies, and the purpose is the reason or motive for the above-mentioned strategies. Findings and conclusions. Through the dramaturgical analysis on the basis of data collection, the conclusions of this study can be shown as the following items. First, the bureaucratic system is the barrier. As a result, the solution should be conducted both top-bottom and bottom-top performance. Second, the government should consider developing S&T strategies as a long-term plan. Third, the current science curricula should be revised. Fourth, universities should fully support and encourage faculty to conduct research along with teaching. Fifth, the quality of education should be improved. Sixth, "new blood" should be inserted in educational institutions. Last, but not least, the existing S&T curricula should be aimed at the international standard.

    The Nuclear Regulatory Authority of Argentina (ARN) is an autonomous body reporting to the Presidency of Argentina, empowered to regulate and control the nuclear activity with regards to radiation and nuclear safety, physical protection and nuclear non-proliferation issues. Under the executive decree 1172/2003, which makes reference to the accessibility of public information to increase transparency of government actions and specially to promote public involvement, ARN has the legal obligation to inform of its activities in an accurate, comprehensive and understandable manner. The re-launching of the nuclear plan in 2006 and the repercussions this provoked on society highlighted the need to reinforce the legitimacy of the regulatory role and the promotion of confidence on its works to ensure the safety of the people. Therefore it was considered necessary to involve the society further in this programme by achieving greater public understanding and awareness of the nuclear regulatory activities. The more the public is conscious of the role of the regulator, conceiving it as a trustworthy and autonomous authority, the easier it is for the regulator to fulfil its obligations. As ARN has a strong commitment with society and considering that communication with the general public, as an external stakeholder, is a means to establishing and maintaining public trust and confidence, the implementation of a new communication programme became a key issue. In this scenario, ARN faced a challenge it was not prepared to handle and thus created a Division to deal with institutional communication and allow and ease the interaction with society. Within this Division, one of the methods chosen to achieve a better interaction with society was the use of a technological tool to attend possible inquiries, increasing and facilitating a greater involvement of the stakeholders.

    Mphemelang J. Ketlhoilwe

    2018-04-01

    Full Text Available Access to energy is a challenge to rural communities, especially among women who are the prime household energy users. This article is based on research carried out in the Tswapong villages in Botswana where energy sources particularly wood, are slowly getting depleted while electricity connection costs remain unaffordable for the poor. The article provides constructivist analysis of experiences in real-life situations among women. Data were generated through observations, documents analysis, interviews and focus group discussions. It has emerged from the research that majority of the respondents use firewood as energy source. Firewood and gas are mainly used for cooking while electricity is mainly used for lighting. The demand for firewood has led to firewood commercialisation, the depletion of preferred firewood tree species and increase in the impact of climate change. The article recommends economic diversification and subsidies to empower the majority of the rural poor to connect to the national electric grid and reduce on firewood dependence. These could be complemented by harnessing of solar energy and low-cost, energy-saving technologies. Subsidies to enable women access to energy services would contribute immensely to the decade of Sustainable Energy for All and to the attainment of the post 2015 sustainable development goal on energy.

    2017-03-01

    Results from this literature review were used to identify the challenges faced by international nurses in their host countries following migration. The increasing strain of nursing shortages in the healthcare system has led to the recruitment of international nurses among many countries. However, following migration, international nurses are faced with challenges that may result in poor integration with their host countries. Using Cooper's five stages for integrative research reviews, a literature search was conducted across seven databases using a PRISMA search strategy. Additional manual searches were also conducted on the end-references of the retrieved articles. The authors then independently reviewed the selected articles using the Joanna Briggs Institute appraisal form to extract and generate the themes for the review. Twenty-four articles were selected for the review. The themes generated included: (i) difficulty orientating; (ii) a longing for what is missing; (iii) professional development and devaluing; (iv) communication barriers; (v) discrimination and marginalization; (vi) personal and professional differences; and (vii) a meaningful support system. By identifying the challenges faced by international nurses, interventions that ensure equal treatment (e.g. multifaceted transition programmes and culturally sensitive 'buddy' systems) can be implemented to help international nurses adapt to their new environments. Adequate communication can be achieved by encouraging international nurses to speak English and learn the colloquial language and non-verbal behaviours used by native nurses. With good integration international nurses may be able to reach their full career potential as professional nurses in their host countries. The adaptation process is a dynamic process that requires effort from both international and native nurses. Thus, any strategies that are developed and implemented must be multifaceted. © 2016 International Council of Nurses.

    Full Text Available Actigraphy as an objective measure of sleep and wakefulness in infants and children has gained popularity over the last 20 years. However, the field lacks published guidelines for sleep-wake identification within pediatric age groups. The scoring rules vary greatly and although sensitivity (sleep agreement with polysomnography is usually high, a significant limitation remains in relation to specificity (wake agreement. Furthermore, accurate algorithm output and sleep-wake summaries usually require prior entry from daily logs of sleep–wake periods and artefact-related information (e.g. non-wear time, involving significant parent co-operation. Scoring criteria for daytime naps remains an unexplored area. Many of the problems facing accuracy of measurement are inherent within the field of actigraphy itself, particularly where sleep periods containing significant movements are erroneously classified as wake, and within quiet wakefulness when no movements are detected, erroneously classified as sleep. We discuss the challenges of actigraphy for pediatric sleep, briefly describe the technical basis and consider a number of technological approaches that may facilitate improved classification of errors in sleep-wake discrimination.

  8. Facing new safety-challenges in a large particle accelerator experiment at CERN

    CERN Document Server

    Schmidt, Reiner

    1999-01-01

    An upgraded safety concept for CMS has been adapted to the size of the project and its organisational challenges under today's budgetary constraints, as well as to the increasing levels of risk. Strong magnetic fields and high radiation levels, including neutrons, pose additional hazards to materials, to operators, to maintenance and to ultimate deposit of activated materials. CMS also fits the insurer's risk-description for modern facilities, i.e. characterised by "higher energy density, more combustible materials and unattended operation". The regulatory environment, consisting essentially of CERN's autonomous regulations as well as of those of its host countries, also need to be satisfied with much attention. To face this challenge, seven distinct safety management tools have been identified, which are described in some detail, namely clear safety objectives, documented safety requirements, open items list, safety ( and design)reviews, safety risk analysis, enforcement of compliance and quality management....

  14. New Technology Changing The Face of Mobile Seismic Networks

    Science.gov (United States)

    Brisbourne, A.; Denton, P.; Seis-Uk

    SEIS-UK, a seismic equipment pool and data management facility run by a consortium of four UK universities (Leicester, Leeds, Cambridge and Royal Holloway, London) completed its second phase in 2001. To compliment the existing broadband equipment pool, which has been deployed to full capacity to date, the consortium undertook a tender evaluation process for low-power, lightweight sensors and recorders, for use on both controlled source and passive seismic experiments. The preferred option, selected by the consortium, was the Guralp CMG-6TD system, with 150 systems ordered. The CMG-6TD system is a new concept in temporary seismic equipment. A 30s- 100Hz force-feedback sensor, integral 24bit digitiser and 3-4Gbyte of solid-state memory are all housed in a single unit. Use of the most recent technologies has kept the power consumption to below 1W and the weight to 3.5Kg per unit. The concept of the disk-swap procedure for obtaining data from the field has been usurped by a fast data download technique using firewire technology. This allows for rapid station servicing, essential when 150 stations are in use, and also ensures the environmental integrity of the system by removing the requirement for a disk access port and envi- ronmentally exposed data disk. The system therefore meets the criteria for controlled source and passive seismic experiments: (1) the single unit concept and low-weight is designed for rapid deployment on short-term projects; (2) the low power consumption reduces the power-supply requirements facilitating deployment; (3) the low self-noise and bandwidth of the sensor make it applicable to passive experiments involving nat- ural sources. Further to this acquisition process, in collaboration with external groups, the SEIS- UK data management procedures have been streamlined with the integration of the Guralp GCF format data into the PASSCAL PDB software. This allows for rapid dissemination of field data and the production of archive-ready datasets

    Chronic Kidney Disease disproportionately affects the poor in Low and Middle Income Countries (LMICs). Mexico exemplifies the difficulties faced in supporting Renal Replacement Therapy (RRT) and providing equitable patient care, despite recent attempts at health reform. The objective of this study is to document the challenges faced by uninsured, poor Mexican families when attempting to access RRT. The article takes an ethnographic approach, using interviewing and observation to generate detailed accounts of the problems that accompany attempts to secure care. The study, based in the state of Jalisco, comprised interviews with patients, their caregivers, health and social care professionals, among others. Observations were carried out in both clinical and social settings. In the absence of organised health information and stable pathways to renal care, patients and their families work extraordinarily hard and at great expense to secure care in a mixed public-private healthcare system. As part of this work, they must navigate challenging health and social care environments, negotiate treatments and costs, resource and finance healthcare and manage a wide range of formal and informal health information. Examining commonalities across pathways to adequate healthcare reveals major failings in the Mexican system. These systemic problems serve to reproduce and deepen health inequalities. A system, in which the costs of renal care are disproportionately borne by those who can least afford them, faces major difficulties around the sustainability and resourcing of RRTs. Attempts to increase access to renal therapies, therefore, need to take into account the complex social and economic demands this places on those who need access most. This paper further shows that ethnographic studies of the concrete ways in which healthcare is accessed in practice provide important insights into the plight of CKD patients and so constitute an important source of evidence in that effort.

  20. Overview of principles and challenges of fusion nuclear technology

    International Nuclear Information System (INIS)

    Abdou, M.

    2007-01-01

    Fusion offers very attractive features as a sustainable, broadly available energy source: no emissions of greenhouse gases, no risk of severe accident, and no long-lived radioactive waste. Significant advances in the science and technology of fusion have been realized in the past decades. Seven countries (EU, Japan, USA, Russia, S. Korea, China, and India) comprising about half the world population are constructing a major magnetic fusion facility, called ITER, in France. The objectives of ITER are to demonstrate self-sustaining burning fusion plasma and to test fusion technologies relevant to fusion reactor. Many challenges to the practical utilization of fusion energy remain ahead. Among these challenges is the successful development of Fusion Nuclear Technology (FNT). FNT includes those fusion system components circumscribing the plasma and responsible for tritium production and processing, heat removal at high temperature and power density, and high heat flux components. FNT components face a new and more challenging environment than experienced by any previous nuclear application. Beyond plasma physics, FNT has most of the remaining feasibility and attractiveness issues in the development of fusion as an energy source. The blanket, a key FNT component, determines the critical path to DEMO. The blanket is exposed to an intense radiation environment. Radioactivity and decay heat can be produced in the structure and other blanket elements. Hence, material choices have a large impact on safety and environmental attractiveness. The unique conditions of the fusion environment include high radiation flux, high surface heat flux, strong 3-D-component magnetic field with large gradients, and ultra-low vacuum. These conditions, together with the requirements for high-temperature operation and tritium self-sufficiency, make blanket design and development challenging tasks. The blanket concepts being considered worldwide can be classified into solid breeders and liquid

    national and international trends have identified concerns over the ability of health and social care workforces in meeting the needs of service users. Attention has increasingly been drawn to problems of recruiting and retaining professionals within higher education; however data in relation to the midwifery profession is scant. to examine the perceptions and experiences of midwifery educators, in south-west England, about the challenges facing them sustaining the education workforce of the future. a mixed methodology approach was adopted involving heads of midwifery education and midwife educators. midwifery participants were recruited from three higher education institutions in south west England. Data collection comprised of self-administered questionnaires plus individual qualitative interviews with heads of midwifery education (n=3), and tape recorded focus groups with midwife academics (n=19). Numerical data were analysed using descriptive statistics. Textual data were analysed for themes that represented the experiences and perspectives of participants. Ethics approval was granted by one University Ethics committee. demographic data suggests that within south-west England, there is a clear ageing population and few in possession of a doctorate within midwifery. The six identified sub-themes represented in the data describe challenges and tensions that midwifery academics experienced in their efforts to attract new recruits and retain those in post in a highly changing educational environment which demands more from a contracting workforce. there remain some serious challenges facing midwifery educators in sustaining the future education workforce, which if unresolved may jeopardise standards of education and quality of care women receive. Active succession planning and more radical approaches that embrace flexible careers will enable educational workforce to be sustained and by a clinically credible and scholarly orientated midwifery workforce.

    Houts, Michael G.

    2016-01-01

    The use of highly enriched uranium (HEU) almost always "helps" space fission systems. Nuclear Thermal Propulsion (NTP) and high power fission electric systems appear able to use < 20% enriched uranium with minimal / acceptable performance impacts. However, lower power, "entry level" systems may be needed for space fission technology to be developed and utilized. Low power (i.e. approx.1 kWe) fission systems may have an unacceptable performance penalty if LEU is used instead of HEU. Are there Ways to Support Non-Proliferation Objectives While Simultaneously Helping Enable the Development and Utilization of Modern Space Fission Power and Propulsion Systems?

    The Large Hadron Collider (LHC) incorporates many technological innovations in order to achieve its design objectives at the lowest cost. The two-in-one magnet design, with the two magnetic channels i ntegrated into a common yoke, has proved to be an economical alternative to two separate rings and allows enough free space in the existing (LEP) tunnel for a possible future re-installation of a lept on ring for e-p physics. In order to achieve the design energy of 7 TeV per beam, with a dipole field of 8.3 T, the superconducting magnet system must operate in superfluid helium at 1.9 K. The LHC wi ll be the first hadron machine to produce appreciable synchrotron radiation which, together with the heat load due to image currents, has to be absorbed at cryogenic temperatures. A brief review of th e machine design is given and some of the main technological and accelerator physics issues are discussed.

    2004-01-01

    Positron Emission Tomography (PET) is a non-invasive nuclear imaging modality allowing biochemical processes to be investigated in vivo with sensitivity in the picomolar range. For this reason, PET has the potential to play a major role in the emerging field of molecular imaging by enabling the study of molecular pathways and genetic processes in living animals non-invasively. The challenge is to obtain a spatial resolution that is appropriate for rat and mouse imaging, the preferred animal models for research in biology, while achieving a sensitivity adequate for real-time measurement of rapid dynamic processes in vivo without violating tracer kinetic principles. An overview of the current state of development of dedicated small animal PET scanners is given, and selected applications are reported and discussed with respect to performance and significance to research in biology

    2016-01-01

    Operating experience from TMI and and more general experience from three decades of nuclear facility operations, have shown the value of safety culture’s contribution to nuclear risk management. More than ever, this particular aspect of human and organizational factors (HOF) is central to the AREVA group’s concerns as it faces new challenges. The first generation of operators commissioned the facilities and optimized their operation. This first phase gave them a better understanding of operations and related limits, particularly through testing and start-up operations and the responses that were found for all of the technical issues that arose. All of these interactions offered opportunities to make the safety challenges of processes and facilities tangible and directly perceptible. The young operators of those bygone years are now the ones who are “in the know” in the organizations, the ones with unique technical know-how and a multi-layered perception of the risks involved. Those first generations of operators, with their unique operational knowledge, are gradually leaving the industrial world. Replacing those skills creates a new set of challenges. Concomitantly, the French nuclear safety authority benefited from these facility start-ups to increase its skills by sharing in the learning process concerning the facilities’ operational realities and in the construction of a safety configuration program, and by gaining a concrete perception of risk. This fostered the mutual trust that is vital and integral to facility safety.

    It is hypothesized that persons who use drugs (PWUD) in Vietnam who are also HIV-positive may face additional challenges in psychosocial outcomes, and these challenges may extend to their family members. In this study, we examined depressive symptoms, stigma, social support, and caregiver burden of HIV-positive PWUD and their family members, compared to the outcomes of HIV-negative PWUD and their family members. Baseline, 3-month, and 6-month assessment data were gathered from 83 PWUD and 83 family members recruited from four communes in Phú Thọ Province, Vietnam. For PWUD, although we observed a general decline in overall stigma over time for both groups, HIV-positive PWUD consistently reported significantly higher overall stigma for all three periods. Depressive symptoms among family members in both groups declined over time; however, family members of HIV-positive PWUD reported higher depressive symptoms across all three periods. In addition, family members of HIV-positive PWUD reported lower levels of tangible support across all three periods. Caregiver burden among family members of HIV-positive PWUD increased significantly over time, whereas the reported burden among family members of HIV-negative PWUD remained relatively unchanged. The findings highlight the need for future interventions for PWUD and family members, with targeted and culturally specific strategies to focus on the importance of addressing additional stigma experienced by PWUD who are HIV-positive. Such challenges may have direct negative impact on their family members' depressive symptoms, tangible support, and caregiver burden.

    Information technology has achieved robust growth which has made it possible for learning to occur quickly. The rapid development of information, communication and technologies (ICT) has initiated an unparalleled transformation in universities all over the world. This development of technology and learning is offering new techniques to represent knowledge, new practices, and new global communities of learners. As a result, today’s economic and social changes force universities to try to find new learning approaches and systems. E-learning seems to be an appropriate approach in this aspect. However, the implementation of e-learning systems in universities is not an easy task because of some challenges related to context, technology, and other challenges. This paper studied the impacts of demographic data and reported the critical points for the decision makers to consider when planning and implementing e-learning in universities. A quantitative approach was used to study the effects of technological and contextual challenges on e-learning implementation in which a questionnaire was used for the data collection. According to the findings of the study, the most important challenges of the implementation of e-learning are related either to organizational (Contextual) and technological (technical) issues. The demographic variables have been found to play a direct and indirect role with the technological and contextual challenges of implementing e-learning. This paper showed that there are some significant differences in the two challenges faced by instructors in terms of the demographic variables. The result revealed that some significant differences exist between demographic variables and the two challenges of e-learning in terms of gender, age, teaching experience, ICT experience and e-learning experience. However, there is no significant difference in terms of e-learning experience. The obtained data, from such study, can provide information about what academic

    The pace of medical innovation continues to increase. The deployment of new technologies in surgery creates many ethical challenges including how to determine safety of the technology, what is the timing and process for deployment of a new technology, how are patients informed before undergoing a new technology or technique, how are the outcomes of a new technology evaluated and how are the responsibilities of individual patients and society at large balanced. Ethical considerations relevant to the implementation of ECMO and robotic surgery are explored to further discussion of how we can optimize the delicate balance between innovation and regulation.

    The presentation will introduce a french national project : CONVERGENCE that has been funded for four years. This project will tackle big data and computational challenges faced by climate modeling community in HPC context. Model simulations are central to the study of complex mechanisms and feedbacks in the climate system and to provide estimates of future and past climate changes. Recent trends in climate modelling are to add more physical components in the modelled system, increasing the resolution of each individual component and the more systematic use of large suites of simulations to address many scientific questions. Climate simulations may therefore differ in their initial state, parameter values, representation of physical processes, spatial resolution, model complexity, and degree of realism or degree of idealisation. In addition, there is a strong need for evaluating, improving and monitoring the performance of climate models using a large ensemble of diagnostics and better integration of model outputs and observational data. High performance computing is currently reaching the exascale and has the potential to produce this exponential increase of size and numbers of simulations. However, post-processing, analysis, and exploration of the generated data have stalled and there is a strong need for new tools to cope with the growing size and complexity of the underlying simulations and datasets. Exascale simulations require new scalable software tools to generate, manage and mine those simulations ,and data to extract the relevant information and to take the correct decision. The primary purpose of this project is to develop a platform capable of running large ensembles of simulations with a suite of models, to handle the complex and voluminous datasets generated, to facilitate the evaluation and validation of the models and the use of higher resolution models. We propose to gather interdisciplinary skills to design, using a component-based approach, a

  13. International conference on challenges faced by technical and scientific support organizations in enhancing nuclear safety. Contributed papers and presentations

    International Nuclear Information System (INIS)

    2007-01-01

    Over the past two decades, the IAEA has conducted a series of major conferences that have addressed topical issues and strategies critical to nuclear safety for consideration by the world's nuclear regulators. More recently, the IAEA organized the International Conference on Effective Nuclear Regulatory Systems - Facing Safety and Security Challenges, held in Moscow in 2006. The Moscow conference was the first of its kind, because it brought together senior regulators of nuclear safety, radiation safety and security from around the world to discuss how to improve regulatory effectiveness with the objective of improving the protection of the public and the users of nuclear and radioactive material. The International Conference on Challenges Faced by Technical and Scientific Support Organizations in Enhancing Nuclear Safety was held in Aix-en-Provence, France, from 23 to 27 April 2007. This conference, again, was the first of its kind, because it was the first to address technical and scientific support organizations (TSOs), the role they play in supporting either the national regulatory bodies or the industry in making optimum safety decisions and the challenges they face in providing this support. This conference provided a forum for the TSOs to discuss these and other issues with the organizations to which they provide this support - that is, the regulators and the operators/industry - as well as with other stakeholders such as research organizations and public authorities. This conference can also be considered to have a link to the Moscow conference. The Moscow conference concluded that effective regulation of nuclear safety is vital for the safe use of nuclear energy and associated technologies, both now and in the future, and is an essential prerequisite for establishing an effective Global Nuclear Safety Regime. The Moscow conference also highlighted the importance of continued and improved international cooperation in the area of nuclear safety. These

    2010-10-01

    Full Text Available Drawing on critical, socio-cultural and sociolinguistic theories of writing, text and voice, this ethnographic study examines the challenges that a mature ESL student and her instructors in a university course on Spanish Language Media face as they co-construct a common understanding of academic literacy and voice in an undergraduate General Studies Program offered by a university in Western Massachusetts. Intertextual analysis of the data suggests that traditional product-based approaches to helping students develop academic literacy might not be very effective. However, to be able to take a different approach, such as the one suggested by genre scholars, both faculty teaching content subjects and writing tutors would need appropriate training.

  16. Rural teachers' views: What are gender-based challenges facing Free Primary Education in Lesotho?

    Pholoho Morojele

    2013-01-01

    Full Text Available This paper gives prominence to rural teachers' accounts of gender-based challenges facing Free Primary Education in Lesotho. It draws on feminist interpretations of social constructionism to discuss factors within the Basotho communities that affect gender equality in the schools. The inductive analysis offered makes use of the data generated from semi-structured interviews with 12 teachers in three primary schools. Basotho culture, superstitious symbolism, and family dynamics are found to be some of the factors that reinforce inequitable gender relations. The findings indicate how teachers exploited these factors to promote the polarisation of gender qualities, and to exalt masculinities at the expense of femininities. The paper argues for the promotion of counter-hegemonic discourses of gender, with an emphasis on conceptions of gender as multiple and fluid human qualities. It explains how paying attention to the cultural architecture of gender formations in localised contexts could become an effective strategy in promoting gender equality in schools.

  17. Why Learning Common Fractions Is Uncommonly Difficult: Unique Challenges Faced by Students With Mathematical Disabilities.

    Science.gov (United States)

    Berch, Daniel B

    In this commentary, I examine some of the distinctive, foundational difficulties in learning fractions and other types of rational numbers encountered by students with a mathematical learning disability and how these differ from the struggles experienced by students classified as low achieving in math. I discuss evidence indicating that students with math disabilities exhibit a significant delay or deficit in the numerical transcoding of decimal fractions, and I further maintain that they may face unique challenges in developing the ability to effectively translate between different types of fractions and other rational number notational formats-what I call conceptual transcoding. I also argue that characterizing this level of comprehensive understanding of rational numbers as rational number sense is irrational, as it misrepresents this flexible and adaptive collection of skills as a biologically based percept rather than a convergence of higher-order competencies that require intensive, formal instruction.

  18. Supply constraints : Australia and Canada coal industry face logistics and capacity challenges

    International Nuclear Information System (INIS)

    Borsato, J.

    2010-01-01

    Australia and Canada are benefiting from a global increase in coal consumption, but face challenges regarding coal and coal export capacity. Coal is Australia's biggest export commodity, accounting for over 50 percent of world coking coal exports, with almost 75 percent of those exports destined for Asian markets, primarily Japan. However, the number of ships delayed at Australian ports hit a record of 223 bulk carriers in early 2010. Compared to Canada, Australia faces greater logistical issues getting coal into port and onto ships at its 9 loading terminals. Two of Canada's 3 major shipping terminals, Westshore and Neptune, have some additional capacity. Its third terminal, Ridley Island, has considerable potential to carry more coal. With 98 percent of all coal moved by rail in Australia, rail issues also hinder growth. A national approach to planning freight transport on both roads and rail is being developed. While infrastructure issues remain the single greatest barrier to export growth for Australia's coal sector, Canada's most immediate issues pertain to mine permitting and mine-site expansion. In 2009, Canada exported 28 million tonnes of coal, 90 percent of it metallurgical. With approximately 70 million tonnes of annual production, mostly in British Columbia and Alberta, coal remains the number one commodity in Canada carried by rails and shipped from ports. 1 fig.

    Directory of Open Access Journals (Sweden)

    Ingrid L. Potgieter

    2017-02-01

    Full Text Available Orientation: South Africa has faced a number of discriminatory practices in the past. Most of these practices are still present today. Although a considerate amount of attention has been given to discrimination based on gender, race and religion, limited emphasis has been placed on discrimination based on disability, specifically within the workplace. Research purpose: The objective of the study was to explore the perceptions of individuals living with a disability with regards to career advancement challenges they face in the South African workplace. Motivation for study: The research literature shows that irrespective of employment equity legislation, employees with disabilities have restricted opportunities to advance in their careers. Research is needed to assist these employees with their career development. Research design, approach and method: A qualitative research design with an exploratory approach was followed. Probability, purposeful and snowballing sampling techniques were applied in this study on 15 employed individuals with declared disabilities. The data were collected by means of semi-structured interviews and the verbatim transcriptions were analysed by content analysis. Main findings/results: The findings indicated that people with disabilities generally experience career advancement challenges and reach career plateau. Managers and colleagues’ lack of knowledge about disability has an adverse impact on the careers of people living with a disability. The study found that human resource practices, especially promotion opportunities, discriminate against employees with disabilities. Furthermore, the study further indicated that there is prejudice against invisible disabilities, and as a result, employees are reluctant to declare their disability. Practical implications: Human resource practitioners and managers need to recognise the influence that disabilities have on the career advancement of individuals living with a

    2006-01-01

    Operating the International Space Station (ISS) involves an indefinite, continuous series of long-duration international missions, and this requires an unprecedented degree of cooperation across multiple sites, organizations, and nations. Both junior and senior mission control personnel have had to find ways to address the cultural challenges inherent in such work, but neither have had systematic training in how to do so. The goals of this study were to identify and evaluate the major cultural challenges faced by ISS mission control personnel and to highlight the approaches that they have found most effective to surmount these challenges. We pay particular attention to the approaches successfully employed by the senior personnel and the training needs identified by the junior personnel. We also evaluate the extent to which the identified approaches and needs are consistent across the two samples. METHODS: Participants included a sample of 14 senior ISS flight controllers and a contrasting sample of 12 more junior controllers. All participants were mission operations specialists chosen on the basis of having worked extensively with international partners. Data were collected using a semi-structured qualitative interview and content analyzed using an iterative process with multiple coders and consensus meetings to resolve discrepancies. RESULTS: The senior respondents had substantial consensus on several cultural challenges and on key strategies for dealing with them, and they offered a wide range of specific tactics for implementing these strategies. Data from the junior respondents will be presented for the first time at the meeting. DISCUSSION: Although specific to American ISS personnel, our results are consistent with recent management, cultural, and aerospace research on other populations. We aim to use our results to improve training for current and future mission control personnel working in international or multicultural mission operations teams.

  1. Physics and technology challenges of B bar B factories

    International Nuclear Information System (INIS)

    Zisman, M.S.

    1991-05-01

    An e + e - collider designed to serve as a B factory requires a luminosity of 3 x 10 33 cm -1 s -1 -- a factor of 20 beyond that of the best present collider and thus presents a considerable challenge to the accelerator builder. To optimize the experiment, it is necessary that the B bar B system have a moving center-of-mass, which implies different energies for the two beams. This feature dictates that a two-ring configuration be used. Accelerator physics issues that arise in such a design are related to the need to tightly focus the beams to a vertical beta function on the order of 1 cm, to bring the beams from two different rings into collision and then clearly separate them again, and to mask the detector region sufficiently to permit measurements with very large beam currents passing through the interaction region. Because the luminosity is limited by the beam-beam interaction, any large improvement must come from considerably increasing both the beam current and the number of bunches in the ring. These choices place many demands on accelerator technology as well as accelerator physics. Vacuum systems must be designed to handle the thermal load from a multi-ampere beam of 8--9 GeV and to maintain an adequate running pressure in the face of a large gas load from synchrotron radiation induced photodesorption. An RF system capable of supporting the high beam currents must be developed. To reduce the growth of potentially strong multibunch instabilities, the cavity higher-order modes must be highly damped to Q ≤ 70. Even with a well optimized RF system, the high beam currents typically mean that wideband multibunch feedback systems are needed to maintain beam stability

    The transition into home hospice care is often a critical time in a patient's medical care. Studies have shown patients and caregivers desire continuity with their physicians at the end of life (EoL). However, it is unclear what roles primary care physicians (PCPs) play and what challenges they face caring for patients transitioning into home hospice care. To understand PCPs' experiences, challenges, and preferences when their patients transition to home hospice care. Nineteen semi-structured phone interviews with PCPs were conducted. Study data were analyzed using standard qualitative methods. Participants included PCPs from 3 academic group practices in New York City. Measured: Physician recordings were transcribed and analyzed using content analysis. Most PCPs noted that there was a discrepancy between their actual role and ideal role when their patients transitioned to home hospice care. Primary care physicians expressed a desire to maintain continuity, provide psychosocial support, and collaborate actively with the hospice team. Better establishment of roles, more frequent communication with the hospice team, and use of technology to communicate with patients were mentioned as possible ways to help PCPs achieve their ideal role caring for their patients receiving home hospice care. Primary care physicians expressed varying degrees of involvement during a patient's transition to home hospice care, but many desired to be more involved in their patient's care. As with patients, physicians desire to maintain continuity with their patients at the EoL and solutions to improve communication between PCPs, hospice providers, and patients need to be explored.

  3. Carbon capture and storage as a corporate technology strategy challenge

    2011-01-01

    Latest estimates suggest that widespread deployment of carbon capture and storage (CCS) could account for up to one-fifth of the needed global reduction in CO 2 emissions by 2050. Governments are attempting to stimulate investments in CCS technology both directly through subsidizing demonstration projects, and indirectly through developing price incentives in carbon markets. Yet, corporate decision-makers are finding CCS investments challenging. Common explanations for delay in corporate CCS investments include operational concerns such as the high cost of capture technologies, technological uncertainties in integrated CCS systems and underdeveloped regulatory and liability regimes. In this paper, we place corporate CCS adoption decisions within a technology strategy perspective. We diagnose four underlying characteristics of the strategic CCS technology adoption decision that present unusual challenges for decision-makers: such investments are precautionary, sustaining, cumulative and situated. Understanding CCS as a corporate technology strategy challenge can help us move beyond the usual list of operational barriers to CCS and make public policy recommendations to help overcome them. - Research highlights: → Presents a corporate technology strategy perspective on carbon capture and storage (CCS). → CCS technology is precautionary, sustaining, cumulative and situated. → Decision-makers need to look beyond cost and risk as barriers to investment in CCS.

    2013-01-01

    Along the nearly 3,200 kilometers (almost 2,000 miles) of the United States–Mexican border, in an area known as the Borderlands, we are witnessing the expression of the challenges of the 21st century. This circular identifies several challenge themes and issues associated with life and the environment in the Borderlands, listed below. The challenges are not one-sided; they do not originate in one country only to become problems for the other. The issues and concerns of each challenge theme flow in both directions across the border, and both nations feel their effects throughout the Borderlands and beyond. The clear message is that our two nations, the United States and Mexico, face the issues in these challenge themes together, and the U.S. Geological Survey (USGS) understands it must work with its counterparts, partners, and customers in both countries.Though the mission of the USGS is not to serve as land manager, law enforcer, or code regulator, its innovation and creativity and the scientific and technical depth of its capabilities can be directly applied to monitoring the conditions of the landscape. The ability of USGS scientists to critically analyze the monitored data in search of signals and trends, whether they lead to negative or positive results, allows us to reach significant conclusions—from providing factual conclusions to decisionmakers, to estimating how much of a natural resource exists in a particular locale, to predicting how a natural hazard phenomenon will unfold, to forecasting on a scale from hours to millennia how ecosystems will behave.None of these challenge themes can be addressed strictly by one or two science disciplines; all require well-integrated, cross-discipline thinking, data collection, and analyses. The multidisciplinary science themes that have become the focus of the USGS mission parallel the major challenges in the border region between Mexico and the United States. Because of this multidisciplinary approach, the USGS

  5. Service user involvement and the restrictive sense of psychiatric categories: the challenge facing mental health nurses.

    2010-05-01

    The active involvement of those people who have at one time used, or who continue to use, mental health services has come to be seen as a central feature of both the policy and the practice of modern mental health care. However, while those people who use mental health services may face a variety of obstacles to active participation in their care and in the provision of mental health services more generally, this paper will draw on the work of Gilles Deleuze, arguably one of the most important philosophers of the late 20th century, to suggest that the language of psychiatry--and, in particular, the attendant valuations or 'sense' of psychiatry's diagnostic categories--serve to restrict the participation of people in their individual care and in the provision of mental health services. Accordingly, it will be suggested that the challenge, as well as the opportunity, that confronts mental health nurses is to facilitate greater, more active user participation by practising in a manner that elicits the resources, capabilities and potential that service users possess, thereby challenging the prevailing and restrictive sense of the diagnostic categories by which people are identified, and by which they come to identify themselves.

    Full Text Available The Professional Executive Secretary has been occupying space increasingly evident in the labor market and organizational structure, both because of market demand, the needs of dynamism in the modern administration that demonstrates the growth of the reference to it. It has sought in his field vision and attitude of performance excellence with fulfilling its role with its own characteristics. This study aims to investigate the general challenges for the Executive Secretariat professional male in contemporary organizations. We defined the following objectives: to analyze the insertion of the male in the profession of Executive Secretary and identify the challenges faced by the Executive Secretary of the males to their development and professional growth. To this end, we performed a literature search, followed by a field survey. It is a qualitative research because data collected, and then make a qualitative analysis of results from selected literature. The survey was conducted in organizations from the public and private, state of Ceará. The sample was represented by professional male graduates in the executive secretariat at the Federal University of Ceará and working in the area. After analyzing the data it was concluded that despite the obstacles to be overcome, the tendency is that these opportunities work for the professional male grow, requiring that all actors in the field to seek gender equity in the profession.

  7. From Toques to Tokes: Two challenges facing nationwide legalization of cannabis in Canada.

    Science.gov (United States)

    Bear, Daniel

    2017-04-01

    In 2015, a new Liberal Government came to power in Canada, elected on a platform that included legalization and regulation of cannabis for recreational purposes. Their legislation, based on recommendations from a Federal Task Force on Marijuana Legalization and Regulation, is due in early April 2017. This commentary utilizes Canadian Federal policy papers, previous literature, and internal and international agreements to examine two key areas critical to the development of a nationwide regulated market for cannabis in Canada; the need to overcome restrictions to legalizing cannabis in United Nations' drug control treaties, and the unique challenges that non-medical cannabis creates for navigating interprovincial trade policies in Canada. Irrespective of UN conventions that appear to prohibit legalization of cannabis the Government is preparing to bring forward legislation as this article goes to print. At the same time significant squabbles impede the selling of even beer and wine inter-provincially in Canada. This paper identifies the challenges facing Canadian legalization efforts, but also shows how the legalization legislation may provide opportunities to engender significant change beyond the simple legalization of a specific drug. This commentary does not argue for any specific course of action for Canada, but rather explores the nuance of legalization absent from the declaration in the Liberal party platform. The paper argues that Canada's efforts may hasten the dismantling of the UN drug control structure, and provide renewed opportunities for intern-provincial trade in Canada.

    Quinlan, Philip R; Groves, Martin; Jordan, Lee B; Stobart, Hilary; Purdie, Colin A; Thompson, Alastair M

    2015-10-01

    The challenges facing biobanks are changing from simple collections of materials to quality-assured fit-for-purpose clinically annotated samples. As a result, informatics awareness and capabilities of a biobank are now intrinsically related to quality. A biobank may be considered a data repository, in the form of raw data (the unprocessed samples), data surrounding the samples (processing and storage conditions), supplementary data (such as clinical annotations), and an increasing ethical requirement for biobanks to have a mechanism for researchers to return their data. The informatics capabilities of a biobank are no longer simply knowing sample locations; instead the capabilities will become a distinguishing factor in the ability of a biobank to provide appropriate samples. There is an increasing requirement for biobanking systems (whether in-house or commercially sourced) to ensure the informatics systems stay apace with the changes being experienced by the biobanking community. In turn, there is a requirement for the biobanks to have a clear informatics policy and directive that is embedded into the wider decision making process. As an example, the Breast Cancer Campaign Tissue Bank in the UK was a collaboration between four individual and diverse biobanks in the UK, and an informatics platform has been developed to address the challenges of running a distributed network. From developing such a system there are key observations about what can or cannot be achieved by informatics in isolation. This article will highlight some of the lessons learned during this development process.

    Science.gov (United States)

    Liu, Bo

    Magnetic hard disk drive (HDD) technology is believed to be one of the most successful examples of modern mechatronics systems. The mechanical beauty of magnetic HDD includes simple but super high accuracy positioning head, positioning technology, high speed and stability spindle motor technology, and head-disk interface technology which keeps the millimeter sized slider flying over a disk surface at nanometer level slider-disk spacing. This paper addresses the challenges and possible approaches on how to further reduce the slider disk spacing whilst retaining the stability and robustness level of head-disk systems for future advanced magnetic disk drives.

  10. Challenges facing the insurance industry since the modernisation of the international nuclear third party liability regime

    International Nuclear Information System (INIS)

    Quere, Alain

    2014-01-01

    events illustrate some of the challenges facing the world of insurance following the modernisation of the international nuclear third party liability regime: - Will the insurance industry be able to find funds corresponding to the new amounts that have been set? - Do the additional damages covered by the revised conventions provide adequate cover for existing risks and will private insurance be able and willing to cover such risks? Nevertheless, the insurance world has changed a great deal since 2004 and there are many additional issues that have arisen since that time. For example, the economic crisis and the introduction of the European Solvency II Directive require insurers to take a more stringent line with their commitments. Moreover, after the Fukushima Daiichi accident, a number of questions have resurfaced: are the new insurance amounts sufficient? The age of 'nuclear renaissance' has long gone and some countries are distancing themselves from nuclear power in light of its questionable costs; are operators paying a fair price in light of the risks incurred? Finally, Europe is keen to play its part and impose its own rules; what will be the consequences of this development? This article reconsiders these challenges in light of the 2004 Protocol (which has not entered into force), by focusing in particular on the situation in Europe. Section I looks back at the history behind the conventions and the key principles they set down. Section II highlights the changes made to the Paris Convention as amended by the 2004 Protocol and the problems facing the insurance industry. Section III provides an overview of the various actors involved in the insurance industry and redefines the necessary insurance foundations to cover the challenges described in Section IV. Finally, Section IV covers all the challenges facing the insurance industry since the modernisation of the international nuclear third party liability regime. (author)

    Bioenergy is increasingly used to help meet greenhouse gas (GHG) and renewable energy targets. However, bioenergy's sustainability has been questioned, resulting in increasing use of life cycle assessment (LCA). Bioenergy systems are global and complex, and market forces can result in significant changes, relevant to LCA and policy. The goal of this paper is to illustrate the complexities associated with LCA, with particular focus on bioenergy and associated policy development, so that its use can more effectively inform policymakers. The review is based on the results from a series of workshops focused on bioenergy life cycle assessment. Expert submissions were compiled and categorized within the first two workshops. Over 100 issues emerged. Accounting for redundancies and close similarities in the list, this reduced to around 60 challenges, many of which are deeply interrelated. Some of these issues were then explored further at a policy-facing workshop in London, UK. The authors applied a rigorous approach to categorize the challenges identified to be at the intersection of biofuels/bioenergy LCA and policy. The credibility of LCA is core to its use in policy. Even LCAs that comply with ISO standards and policy and regulatory instruments leave a great deal of scope for interpretation and flexibility. Within the bioenergy sector, this has led to frustration and at times a lack of obvious direction. This paper identifies the main challenge clusters: overarching issues, application and practice and value and ethical judgments. Many of these are reflective of the transition from application of LCA to assess individual products or systems to the wider approach that is becoming more common. Uncertainty in impact assessment strongly influences planning and compliance due to challenges in assigning accountability, and communicating the inherent complexity and uncertainty within bioenergy is becoming of greater importance. The emergence of LCA in bioenergy governance is

    This qualitative study explored the challenges that Greek parents/caregivers of children with controlled epilepsy (CwE) face regarding the disorder. Interviews were conducted based on open-ended questions guided by a review of the literature. A total of 91 parents/caregivers were recruited by neurologists at the neurology clinics of two Athens public hospitals. A hermeneutic phenomenological approach was used to explore parent/caregiver experiences. The data were grouped and analyzed through a textual interpretation. Two key challenges were identified for parents of CwE: the disclosure of epilepsy and the absence of adequate information about coping with epilepsy. Parents in Greece were hesitant to reveal their child's epilepsy to school staff and their wider social milieu. Also, although satisfied with the patient-centered approach they experienced with their hospital doctor, parents/caregivers found that they needed more education about the existing sources of psychosocial and emotional support to cope with their child's epilepsy personally and as a family. Finally, the parents/caregivers who let their child know about the epilepsy and discussed the implications with the child found that parent-child communication improved. This study provides valuable insight into the impact of epilepsy on parents of CwE, which might help hospital and school staff support families with greater understanding, sensitivity, and skill. The findings suggest that Greek authorities should staff hospitals and schools with experts and more systematically advertise sources of information about epilepsy and ways to cope with it.

  18. Polycentrism in Global Health Governance Scholarship Comment on "Four Challenges That Global Health Networks Face".

    Science.gov (United States)

    Tosun, Jale

    2017-05-23

    Drawing on an in-depth analysis of eight global health networks, a recent essay in this journal argued that global health networks face four challenges to their effectiveness: problem definition, positioning, coalition-building, and governance. While sharing the argument of the essay concerned, in this commentary, we argue that these analytical concepts can be used to explicate a concept that has implicitly been used in global health governance scholarship for quite a few years. While already prominent in the discussion of climate change governance, for instance, global health governance scholarship could make progress by looking at global health governance as being polycentric. Concisely, polycentric forms of governance mix scales, mechanisms, and actors. Drawing on the essay, we propose a polycentric approach to the study of global health governance that incorporates coalitionbuilding tactics, internal governance and global political priority as explanatory factors. © 2018 The Author(s); Published by Kerman University of Medical Sciences.

However, for those in the adolescent and young adult (AYA age-group of 15–30 years with ALL, there has not been the same degree of improvement. Historically, pediatric and adult providers have utilized different treatment approaches based on clinical trials. However, studies that have compared the outcome of AYA patients with ALL treated on pediatric or adult clinical trials have generally shown substantially better outcomes for this patient population treated with the pediatric trials. Additionally, hematopoietic stem cell transplantation has been considered as part of intensified therapy for AYA patients with ALL. Herein, we review the outcomes with chemotherapy alone and with hematopoietic stem cell transplantation, and explore the challenges faced in determining the ideal therapy for the AYA population of patients.

    Obenson, Ken; Enow Orock, George

    2017-08-01

    A properly operated death investigation system (DIS) serves multiple stakeholders. Law enforcement, public health departments and members of the public, benefit in various ways from the information that it provides. This information must be collected systematically and efficiently. The system must also be flexible enough to respond to pressures on its resources such as occurs during mass disasters. These obligations on a DIS require an investment of public money. However even in affluent Western countries the recent world economic crisis has led to a cut in spending on public services that affect both the healthcare system and services associated with death investigation. Although pathologists and other stake holders (judiciary, police, families) would like to see death investigations conducted to international standards, the fact is that policy makers in resource limited countries face additional population health and sociopolitical pressures which generally result in very little funding for the service. The purpose of this paper is to review some of the challenges that impede the proper functioning of a death investigation system in resource limited countries in Sub-Saharan Africa and the Caribbean. Possible solutions are discussed. Copyright © 2017. Published by Elsevier Ltd.

    2016-07-01

    The emergence of multidrug resistant bacterium threatens to unravel global healthcare systems, built up over centuries of medical research and development. Current antibiotics have little resistance against this onslaught as bacterium strains can quickly evolve effective defense mechanisms. Fortunately, alternative therapies exist and, at the forefront of research lays the photodynamic inhibition approach mediated by porphyrin based photosensitizers. This review will focus on the development of various porphyrins compounds and their incorporation as small molecules, into polymers, fibers and thin films as practical therapeutic agents, utilizing photodynamic therapy to inhibit a wide spectrum of bacterium. The use of photodynamic therapy of these porphyrin molecules are discussed and evaluated according to their electronic and bulk material effect on different bacterium strains. This review also provides an insight into the general direction and challenges facing porphyrins and derivatives as full-fledged therapeutic agents and what needs to be further done in order to be bestowed their rightful and equal status in modern medicine, similar to the very first antibiotic; penicillin itself. It is hoped that, with this perspective, new paradigms and strategies in the application of porphyrins and derivatives will progressively flourish and lead to advances against disease. © 2016 WILEY-VCH Verlag GmbH & Co.

The data are from a broader study, conducted in 2005 at the same hospital as part of a baseline assessment of maternal health services. 31 maternal HCPs; nine midwives and 14 nurses and eight doctors. the quality of care provided for women and infants at this Palestinian public hospital is substandard. The maternal HCPs work within a difficult and resource-constrained environment. ISSUES INCLUDE: high workload, poor compensation, humiliation in the workplace, suboptimal supervision and the absence of professional support and guidance. Midwives are perceived to be at the bottom of the health professional hierarchy. there is a need for managers and policy makers to enable maternal HCPs to provide better quality care for women and infants during childbirth, through facilitating the roles of midwives and nurses and creating a more positive and resourceful environment. Palestinian midwives need to increase their knowledge and use evidence-based practices during childbirth. They need to unite and create their own circle of professional support in the form of a Palestinian midwifery professional body. Copyright © 2009 Elsevier Ltd. All rights reserved.

    Professional guidelines have addressed ethical dilemmas posed by a few types of nontraditional procreative arrangements (e.g., gamete donations between family members), but many questions arise regarding how providers view and make decisions about these and other such arrangements. Thirty-seven ART providers and 10 patients were interviewed in-depth for approximately 1 h each. Interviews were systematically analyzed. Providers faced a range of challenges and ethical dilemmas concerning both the content and the process of decisions about requests for unconventional interfamilial and other reproductive combinations. Providers vary in how they respond - what they decide, who exactly decides (e.g., an ethics committee or not), and how - often undergoing complex decision-making processes. These combinations can involve creating or raising the child, and can shift over time - from initial ART treatment through to the child's birth. Patients' requests can vary from fully established to mere possibilities. Arrangements may also be unstable, fluid, or unexpected, posing challenges. Difficulties emerge concerning not only familial but social, combinations (e.g., between friends). These arrangements can involve blurry and confusing roles, questions about the welfare of the unborn child, and unanticipated and unfamiliar questions about how to weigh competing moral and scientific concerns - e.g., the autonomy of the individuals involved, and the potential risks and benefits. Clinicians may feel that these requests do not "smell right"; and at first respond with feelings of "yuck," and only later, carefully and explicitly consider the ethical principles involved. Proposed arrangements may, for instance, initially be felt to involve consanguineous individuals, but not in fact do so. Obtaining and verifying full and appropriate informed consent can be difficult, given implicit familial and/or cultural expectations and senses of duty. Social attitudes are changing, yet patients

  13. Cyber crime: can a standard risk analysis help in the challenges facing business continuity managers?

    Vande Putte, Danny; Verhelst, Marc

    Risk management has never been easy. Finding efficient mitigating measures is not always straightforward. Finding measures for cyber crime, however, is a really huge challenge because cyber threats are changing all the time. As the sophistication of these threats is growing, their impact increases. Moreover, society and its economy have become increasingly dependent on information and communication technologies. Standard risk analysis methodologies will help to score the cyber risk and to place it in the risk tolerance matrix. This will allow business continuity managers to figure out if there is still a gap with the maximum tolerable outage for time-critical business processes and if extra business continuity measures are necessary to fill the gap.

  14. Issues facing the Australian Health Technology Assessment Review of medical technology funding.

    2010-07-05

    The Australian Health Technology Assessment Review has the potential to have a major effect on the availability of new medical technology and the listing of associated medical procedures on the Medicare Benefits Schedule. Despite this, only about 15% of submissions to the Review came from "medical associations". Pharmaceutical and medical technologies are inherently different, and there are a number of difficulties associated with evaluating medical technology using the same process and evidence levels as those used for pharmaceuticals. The current sequential and lengthy processing of new medical technology and procedures is delaying access to beneficial medical technology and could be substantially reduced. There is currently no effective funding process for medical technology classified as capital equipment or consumables and disposables. This has created a perverse incentive in favour of using funded implantable prostheses based on access to funding rather than superior clinical effectiveness. The existing horizon scanning process could be better used to not only identify all potentially cost-effective new and emerging medical technology and procedures as early as possible, but also to identify gaps in the evidence.

    Veterinarians are faced with significant conflicts of interest when issuing certificates for the transport and slaughter of acutely injured and casualty livestock. In a recent Policy Delphi study, emergency and casualty slaughter certification was a key concern identified by veterinary professionals in Ireland. In this case study (the third in a series of three resulting from a research workshop exploring challenges facing the veterinary profession in Ireland; the other two case studies investigate clinical veterinary services and the on-farm use of veterinary antimicrobials), we aim to provide a value-based reflection on the constraints and opportunities for best practice in emergency and casualty slaughter certification in Ireland. Using a qualitative focus group approach, this study gathered evidence from relevant stakeholders, namely a representative from the regulatory body, local authority veterinarians with research experience in emergency slaughter, an animal welfare research scientist, official veterinarians from the competent authority, a private veterinary practitioner, and a member of a farming organisation. Results revealed a conflict between the responsibility of private veterinary practitioners (PVPs) to safeguard the welfare of acutely injured bovines on-farm and the client's commercial concerns. As a consequence, some PVPs may feel under pressure to certify, for example, an acutely injured animal for casualty slaughter instead of recommending either on-farm emergency slaughter or disposal by the knackery service. Among Official Veterinarians, there are concerns about the pressure within processing plants to accept acutely injured livestock as casualty animals. Confusion pertaining to legislation and definition of fitness to travel also contribute to these dilemmas. Conflicts of interest arise due to the gap between governance and provision to facilitate on-farm emergency slaughter of livestock. Increased availability and acceptance of on

    2010-01-01

    The National Aeronautics and Space Administration (NASA) is currently undergoing a substantial redirection. Notable among the changes occurring within NASA is the stated emphasis on technology development, integration, and demonstration. These new changes within the Agency should have a positive impact on the GN&C discipline given the potential for sizeable investments for technology development and in-space demonstrations of both Autonomous Rendezvous & Docking (AR&D) systems and Autonomous Precision Landing (APL) systems. In this paper the NASA Technical Fellow for Guidance, Navigation and Control (GN&C) provides a summary of the present technical challenges, critical needs, and future technological directions for NASA s GN&C engineering discipline. A brief overview of the changes occurring within NASA that are driving a renewed emphasis on technology development will be presented as background. The potential benefits of the planned GN&C technology developments will be highlighted. This paper will provide a GN&C State-of-the-Discipline assessment. The discipline s readiness to support the goals & objectives of each of the four NASA Mission Directorates is evaluated and the technical challenges and barriers currently faced by the discipline are summarized. This paper will also discuss the need for sustained investments to sufficiently mature the several classes of GN&C technologies required to implement NASA crewed exploration and robotic science missions.

    The WERF Nutrient Challenge is a multi-year collaborative research initiative established in 2007 to develop and provide current information about wastewater treatment nutrients (specifically nitrogen and phosphorus in wastewater), their characteristics, and bioavailability in aquatic environments to help regulators make informed decisions. The Nutrient Challenge will also provide data on nutrient removal so that treatment facilities can select sustainable, cost-effective methods and technologies to meet permit limits. To meet these goals, the Nutrient Challenge has teamed with a wide array of utilities, agencies, consultants, universities and other researchers and practitioners to collaborate on projects that advance these goals. The Nutrient Challenge is focusing on a different approach to collaborating and leveraging resources (financial and intellectual) on research projects by targeting existing projects and research that correspond with its goals and funding those aspects that the Nutrient Challenge identified as a priority. Because the Nutrient Challenge is focused on collaboration, outreach is an absolutely necessary component of its effectiveness. Through workshops, webinars, a web portal and online compendium, published papers, and conference lectures, the Nutrient Challenge is both presenting important new information, and soliciting new partnerships.

  8. THE SOCIAL AND OCCUPATIONAL HEALTH PROBLEMS OF CHILD LABOUR: A CHALLENGE THE WORLD IS FACING

    2012-03-01

    Full Text Available Eliminating child labour is one of the biggest challenges that the world is facing. Child labour not only causes damage to a child’s physical and mental health but also keeps him deprived of his basic rights to education, development, and freedom. Children of lower socio-economic class are known to be inducted as child labour. The main causes of child labour include poverty, unemployment, excess population and urbanization. The construction sector is one of the most hazardous working environments especially for children. Children are exposed to dangerous machinery causing fatal and non-fatal injuries, while operating or working near them. Children are exposed to strenuous labour, which can affect the musculo-skeletal development of the children. In industries, child workers are exposed to various physical, mental, social occupational hazards resulting in lower growth and poor health status. Working long hours, child labourers are often denied a basic school education, normal social interaction, personal development and emotional support from their family. The Child Labour Act was implemented in India in 1986 that outlaws child labour in certain areas and sets the minimum age of employment at fourteen. Eradicating poverty is only the first step on the road for eliminating child labour. There is an urgent need for intensive focus and research along with political and practical decisions to improve the conditions of working children for the betterment of their health and development. Proper education of the children and banning child labor will help in boosting the success of the country.

    Full Text Available According to the 2010 UNAIDS Report, an estimated 320 000 (or 20% fewer people died of AIDS-related causes in 2009 when compared to figures in 2004 in sub-Saharan Africa, when antiretroviral therapy was markedly expanded (UNAIDS, 2010. This decreased mortality rate offers hope for HIV-infected people to plan a future, part of which will include dating and sexual relationships. The Report cites KwaZulu-Natal in South Africa as being at the heart of the HIV/AIDS epidemic; this article is based on research on dating and sexuality among HIV-positive people in KwaZulu-Natal. Dating and sexuality are an integral part of living. Yet HIV-positive persons are denied intimacy at a time when this is most needed (Kasiram in Kasiram, Partab & Dano, 2006. Little is known about the full range of sexual adaptations that HIV-infected individuals choose (Schiltz & Sandfort, 2000. Kasiram, Partab, Dano and Van Greunen (2003:9 cite interaction and intimacy among HIV-positive persons as a neglected research focus, while Painter (2001 adds that insufficient attention is afforded to couple relationships for infected people. An important reason that motivated this study on dating and sexual challenges faced by HIV-positive people was the first author’s (the main researcher’s personal experience of being HIV positive and counselling and life coaching HIV-positive people.

    2004-01-01

    Many applications, from linear colliders to free-electron lasers, passing through light sources and many other electron sources, require high brightness electron beams, usually produced by photo-injectors. Because certain parameters of these applications differ by several orders of magnitude, various solutions were implemented for the design and construction of the three main parts of the photo-injectors: lasers, photocathodes and guns. This paper summarizes the different requirements, how they lead to technological challenges and how R&D programs try to overcome these challenges. Some examples of state-of-the-art parts are presented.

    The Office of Site Closure (OSC) was formed in November 1999 when the Department of Energy's (DOE's) Office of Environmental Management (EM) reorganized to focus specifically on site cleanup and closure. OSC's objective is to achieve safe and cost-effective cleanups and closures that are protective of our workers, the public, and the environment, now and in the future. Since its inception, OSC has focused on implementing a culture of safe closure, with emphasis in three primary areas: complete our responsibility for the Closure Sites Rocky Flats, Mound, Fernald, Ashtabula, and Weldon Spring; complete our responsibility for cleanup at sites where the DOE mission has been completed (examples include Battelle King Avenue and Battelle West Jefferson in Columbus, and General Atomics) or where other Departmental organizations have an ongoing mission (examples include the Brookhaven, Livermore, or Los Alamos National Laboratories, and the Nevada Test Site); and create a framework a nd develop specific business closure tools that will help sites close, such as guidance for and decisions on post-contract benefit liabilities, records retention, and Federal employee incentives for site closure. This paper discusses OSC's 2001 progress in achieving site cleanups, moving towards site closure, and developing specific business closure tools to support site closure. It describes the tools used to achieve progress towards cleanup and closure, such as the application of new technologies, changes in contracting approaches, and the development of agreements between sites and with host states. The paper also identifies upcoming challenges and explores options for how Headquarters and the sites can work together to address these challenges. Finally, it articulates OSC's new focus on oversight of Field Offices to ensure they have the systems in place to oversee contractor activities resulting in site cleanups and closures

    Cryogenic engine capable of delivering 200 kN thrust is being developed for the first time in the country by ISRO for powering the upper stage of GSLV Mk-III, the next generation launch vehicle of ISRO capable of launching four tonne class satellites to Geo-synchronous Transfer Orbit(GTO). Development of this engine started a decade ago when various sub-systems development and testing were taken up. Starting with injector element development, the design, realization and testing of the major sub-systems viz the gas generator, turbopumps, start-up system and thrust chamber have been successfully done in a phased manner before conducting a series of developmental tests in the integrated engine mode. Apart from the major sub-systems, many critical components like the igniter, control components etc were independently developed and qualified. During the development program many challenges were faced in almost all areas of propulsion engineering. Systems engineering of the engine was another key challenge in the realization. This paper gives an outlook on various technological challenges faced in the key areas related to the engine development, insight to the solutions and measures taken to overcome the challenges.

  18. Reducing Weight for Transportation Applications: Technology Challenges and Opportunities

    Science.gov (United States)

    Taub, Alan I.

    Today's land, sea and air transportation industries — as a business necessity — are focused on technology solutions that will make vehicles more sustainable in terms of energy, the environment, safety and affordability. Reducing vehicle weight is a key enabler for meeting these challenges as well as increasing payload and improving performance. The potential weight reductions from substituting lightweight metals (advanced high-strength steels, aluminum, magnesium and titanium alloys) are well established. For magnesium castings, weight savings of 60% have been reported [1]. The value of weight reduction depends on the transportation sector and ranges from about 5/kg saved for automobiles to over 500/kg saved for aircraft [2]. The challenge is to optimize the material properties and develop robust, high volume, manufacturing technologies and the associated supply chain to fabricate components and subsystems at the appropriate cost for each application.

    2016-04-01

    The uptake and acceptance of Geographic Information Systems (GIS) technology has increased since the early 1990s and public health applications are rapidly expanding. In this paper, we summarize the common uses of GIS technology in the public health sector, emphasizing applications related to mapping and understanding of parasitic diseases. We also present some of the success stories, and discuss the challenges that still prevent a full scope application of GIS technology in the public health context. Geographical analysis has allowed researchers to interlink health, population and environmental data, thus enabling them to evaluate and quantify relationships between health-related variables and environmental risk factors at different geographical scales. The ability to access, share and utilize satellite and remote-sensing data has made possible even wider understanding of disease processes and of their links to the environment, an important consideration in the study of parasitic diseases. For example, disease prevention and control strategies resulting from investigations conducted in a GIS environment have been applied in many areas, particularly in Africa. However, there remain several challenges to a more widespread use of GIS technology, such as: limited access to GIS infrastructure, inadequate technical and analytical skills, and uneven data availability. Opportunities exist for international collaboration to address these limitations through knowledge sharing and governance.

    2007-07-01

    Full Text Available Abstract Background Infant feeding is a subject of worry in prevention of mother to child transmission (pMTCT programmes in settings where breastfeeding is normative. Nurse-counsellors, expected to counsel HIV-positive women on safer infant feeding methods as defined in national/international guidelines, are faced with a number of challenges. This study aims to explore the experiences and situated concerns of nurses working as infant feeding counsellors to HIV-positive mothers enrolled in pMTCT programmes in the Kilimanjaro region, northern Tanzania. Methods A qualitative study was conducted using in-depth interviews and focus group discussions (FGDs with 25 nurse-counsellors at four pMTCT sites. Interviews were handwritten and FGDs were tape-recorded and transcribed, and the programme Open Code assisted in sorting and structuring the data. Analysis was performed using 'content analysis.' Results The findings revealed a high level of stress and frustration among the nurse-counsellors. They found themselves unable to give qualified and relevant advice to HIV-positive women on how best to feed their infants. They were confused regarding the appropriateness of the feeding options they were expected to advise HIV-positive women to employ, and perceived both exclusive breastfeeding and exclusive replacement feeding as culturally and socially unsuitable. However, most counsellors believed that formula feeding was the right way for an HIV-positive woman to feed her infant. They expressed a lack of confidence in their own knowledge of HIV and infant feeding, as well as in their own skills in assessing a woman's possibilities of adhering to a particular method of feeding. Moreover, the nurses were in general not comfortable in their newly gained role as counsellors and felt that it undermined the authority and trust traditionally vested in nursing as a knowledgeable and caring profession. Conclusion The findings illuminate the immense burden placed on

    This article aims to consider some relevant challenges to the provision of "new prevention technologies" in health services in a scenario where the "advances" in the global response to AIDS control are visible. We take as material for analysis the information currently available on the HIV post-exposure prophylaxis (PEP) and pre-exposure prophylaxis (PrEP), treatment as prevention (TASP) and over the counter. The methodology consisted of the survey and analysis of the Biblioteca Virtual em Saúde (BVS: MEDLINE, LILACS, WHOLIS, PAHO, SciELO) articles that addressed the issue of HIV prevention and care in the context of so-called new prevention technologies. The results of the studies show that there is assistance on the ground of clinics for the treatment of disease responses, but there are several challenges related to the sphere of prevention. The articles list some challenges regarding to management, organization of services and the attention given by health professionals to users. The current context shows evidence of the effectiveness of antiretroviral therapy in reducing the risk of HIV transmission, but the challenges for the provision of preventive technologies in health services permeate health professionals and users in their individual dimensions and health services in organizational and structural dimension. Interventions should be made available in a context of community mobilization; there should be no pressure on people to make HIV testing, antiretroviral treatment or for prevention. In the management is responsible for the training of health professionals to inform, clarify and make available to users, partners and family information about the new antiretroviral use strategies.

  5. Stereotype Threat: A Qualitative Study of the Challenges Facing Female Undergraduate Engineering Students

    Entsminger, J. R., II

    From a sociocultural point of view, this qualitative case study explored how upper-level, female undergraduate engineering students perceived the possibility of or experience with stereotype threat as shaping their experiences. The study also investigated how these students explained their reasons for choosing their engineering major, the challenges they encountered in the major, and their reasons for persevering in spite of those challenges. Using Steele and Aronson's (1995) stereotype threat theory as a framework, and considering the documented underrepresentation of females in engineering, the study sought to examine how stereotype threat shaped the experiences of these students and if stereotype threat could be considered a valid reason for the underrepresentation. The study was conducted at a large, four-year public university. First, students in the College of Engineering and Engineering Technology completed the Participant Screening Survey. Based on responses from the survey, six female engineering students from the college were identified and invited to participate in the study. The participants came from the following majors: Electrical Engineering, Industrial and Systems Engineering, and Mechanical Engineering. After receiving the study consent letter and agreeing to participate, the students were involved in a 90-minute focus group meeting, a 45-minute one-on-one interview, and a 30-minute follow-up interview. After conducting the data collection methods, the data were then transcribed, analyzed, and coded for theme development. The themes that emerged coincided with each research question. The themes highlighted the complex interactions and experiences shared by the female engineering majors. The female students were enveloped in an environment where there existed an increased risk for activating stereotype threat. In addition, the female students described feeling pushed to prove to themselves and to others that the negative stereotype that 'females

    Technology could transform routine decision making by anticipating patients' information needs, assessing where patients are with decisions and preferences, personalizing educational experiences, facilitating patient-clinician information exchange, and supporting follow-up. This study evaluated whether patients and clinicians will use such a decision module and its impact on care, using 3 cancer screening decisions as test cases. Twelve practices with 55,453 patients using a patient portal participated in this prospective observational cohort study. Participation was open to patients who might face a cancer screening decision: women aged 40 to 49 who had not had a mammogram in 2 years, men aged 55 to 69 who had not had a prostate-specific antigen test in 2 years, and adults aged 50 to 74 overdue for colorectal cancer screening. Data sources included module responses, electronic health record data, and a postencounter survey. In 1 year, one-fifth of the portal users (11,458 patients) faced a potential cancer screening decision. Among these patients, 20.6% started and 7.9% completed the decision module. Fully 47.2% of module completers shared responses with their clinician. After their next office visit, 57.8% of those surveyed thought their clinician had seen their responses, and many reported the module made their appointment more productive (40.7%), helped engage them in the decision (47.7%), broadened their knowledge (48.1%), and improved communication (37.5%). Many patients face decisions that can be anticipated and proactively facilitated through technology. Although use of technology has the potential to make visits more efficient and effective, cultural, workflow, and technical changes are needed before it could be widely disseminated. © 2017 Annals of Family Medicine, Inc.

    2016-04-01

    Full Text Available This paper examines the Nigerian economy and the tendency for its growth in the face of several socio-political challenges facing the country, which have hampered the rate of economic development in spite of the tremendous human and material resources inherent. The paper identifies the socio-political challenges to include corruption, poverty, unemployment, insecurity, politics and governance, among others. The central argument of the paper is that steady economic growth can be achieved and financial crisis mitigated in Nigeria, if the effects of socio-political challenges, which are the key factors that have contributed to the high poverty, unemployment and economic instability in the country, are minimised. To ensure economic growth and move the country forward politically and economically, government must be more accountable in managing the nation’s resources in order to avoid wastage, poverty and unemployment. Close attention should be given to those socio-political challenges in the formulation of policies that aimed at maintaining economic growth at a level commensurate with the country’s growth rate. This study put forward that government must be proactive in all issues relating to the socio-political challenges to prevent resource mismanagement, poverty, unemployment, insecurity and slow economic growth in future.

    Wearable face-mounted computers such as Google Glass™ , Microsoft HoloLens™, and Oculus' Rift ® , are increasingly being tested in hospital care. These devices challenge social etiquette, raise privacy issues, and may disrupt the intimacy of the doctor patient relationship. We aimed to determine patients' perception of and their privacy concerns with an archetype of wearable face-mounted computer devices, Google Glass. Hospitalized inpatients were asked about their familiarity with Glass, how comfortable they would be and if they would be concerned about privacy if their physician wore Glass, if the use of Glass would affect their trust in their physician, and if they would want their physician to wear Glass if it improved their care. Most (73%) respondents were unfamiliar with Glass, though 64% would be comfortable if their doctor wore Glass. Under half (46%) of respondents were concerned about privacy with the use of Glass. Seventy-six percent (76%) of respondents stated their doctor wearing Glass would not affect their trust in their doctor. Patients concerned about their privacy were less likely to trust their doctor if their doctor wore Glass (17% vs. 0%, ptechnology. While some patients expressed concerns about privacy, patients were much less concerned about wearable technologies affecting the trust they have in their physician.

  15. RESPONSIVENESS, LANGUAGE, AND ALIGNMENT: REFLECTIONS ON SOME CHALLENGES FOR HEALTH TECHNOLOGY ASSESSMENT.

    2015-01-01

    Health systems around the world cope with the challenge of difficult economic times, and the value of health technology assessment (HTA) is increasing. Making the right choices, with limited resources, in the face of increasingly complex technologies requires decisions informed by data and analyses that help us to manage the risks involved. Those who undertake and use HTA can play a greater role in helping decision makers meet these challenges; they need to think how to define innovation and respond to it, how to communicate their analyses, and, critically, how to align their work with the ambitions of their health systems. HTA can become a key health system enabler without compromising its objectivity or independence. It can say that it is too early to determine the value of a new technology when the data simply will not support a safe decision. However, it can also be bold and recommend the managed introduction of new technologies, even when the when the data is immature, provided that the health system understands the risks and there is a plausible case for believing that further research will support the value proposition. The goal for HTA is to be able confidently to do both.

    We often identify people using face images. This is true in occupational settings such as passport control as well as in everyday social environments. Mapping between images and identities assumes that facial appearance is stable within certain bounds. For example, a person's apparent age, gender and ethnicity change slowly, if at all. It also assumes that deliberate changes beyond these bounds (i.e., disguises) would be easy to spot. Hyper-realistic face masks overturn these assumptions by allowing the wearer to look like an entirely different person. If unnoticed, these masks break the link between facial appearance and personal identity, with clear implications for applied face recognition. However, to date, no one has assessed the realism of these masks, or specified conditions under which they may be accepted as real faces. Herein, we examined incidental detection of unexpected but attended hyper-realistic masks in both photographic and live presentations. Experiment 1 (UK; n = 60) revealed no evidence for overt detection of hyper-realistic masks among real face photos, and little evidence of covert detection. Experiment 2 (Japan; n = 60) extended these findings to different masks, mask-wearers and participant pools. In Experiment 3 (UK and Japan; n = 407), passers-by failed to notice that a live confederate was wearing a hyper-realistic mask and showed limited evidence of covert detection, even at close viewing distance (5 vs. 20 m). Across all of these studies, viewers accepted hyper-realistic masks as real faces. Specific countermeasures will be required if detection rates are to be improved.

    The United States, the Department of Energy (DOE) and its National Laboratories, including the Pacific Northwest National Laboratory (PNNL), are facing a serious attrition of nuclear scientists and engineers and their capabilities through the effects of aging staff. Within the DOE laboratories, 75% of nuclear personnel will be eligible to retire by 2010. It is expected that there will be a significant loss of senior nuclear science and technology staff at PNNL within five years. PNNL's nuclear legacy is firmly rooted in the DOE Hanford site, the World War II Manhattan Project, and subsequent programs. Historically, PNNL was a laboratory where 70% of its activities were nuclear/radiological, and now just under 50% of its current business science and technology are nuclear and radiologically oriented. Programs in the areas of Nuclear Legacies, Global Security, Nonproliferation, Homeland Security and National Defense, Radiobiology and Nuclear Energy still involve more than 1,000 of the 3,800 current laboratory staff, and these include more than 420 staff who are certified as nuclear/radiological scientists and engineers.

    2015-01-01

    Medical education is rapidly changing, influenced by many factors including the changing health care environment, the changing role of the physician, altered societal expectations, rapidly changing medical science, and the diversity of pedagogical techniques. Changes in societal expectations put patient safety in the forefront, and raises the ethical issues of learning interactions and procedures on live patients, with the long-standing teaching method of "see one, do one, teach one" no longer acceptable. The educational goals of using technology in medical education include facilitating basic knowledge acquisition, improving decision making, enhancement of perceptual variation, improving skill coordination, practicing for rare or critical events, learning team training, and improving psychomotor skills. Different technologies can address these goals. Technologies such as podcasts and videos with flipped classrooms, mobile devices with apps, video games, simulations (part-time trainers, integrated simulators, virtual reality), and wearable devices (google glass) are some of the techniques available to address the changing educational environment. This article presents how the use of technologies can provide the infrastructure and basis for addressing many of the challenges in providing medical education for the future.

  12. Nanotechnology risk perceptions and communication: emerging technologies, emerging challenges.

    Science.gov (United States)

    Pidgeon, Nick; Harthorn, Barbara; Satterfield, Terre

    2011-11-01

    Nanotechnology involves the fabrication, manipulation, and control of materials at the atomic level and may also bring novel uncertainties and risks. Potential parallels with other controversial technologies mean there is a need to develop a comprehensive understanding of processes of public perception of nanotechnology uncertainties, risks, and benefits, alongside related communication issues. Study of perceptions, at so early a stage in the development trajectory of a technology, is probably unique in the risk perception and communication field. As such it also brings new methodological and conceptual challenges. These include: dealing with the inherent diversity of the nanotechnology field itself; the unfamiliar and intangible nature of the concept, with few analogies to anchor mental models or risk perceptions; and the ethical and value questions underlying many nanotechnology debates. Utilizing the lens of social amplification of risk, and drawing upon the various contributions to this special issue of Risk Analysis on Nanotechnology Risk Perceptions and Communication, nanotechnology may at present be an attenuated hazard. The generic idea of "upstream public engagement" for emerging technologies such as nanotechnology is also discussed, alongside its importance for future work with emerging technologies in the risk communication field. © 2011 Society for Risk Analysis.

    O'Toole, Stephanie; Lambert, Veronica; Gallagher, Pamela; Shahwan, Amre; Austin, Joan K

    2016-04-01

    The aim of this qualitative study was to explore the challenges that parents of children with epilepsy experienced when engaging in dialog with their child about epilepsy and epilepsy-related issues. Using a qualitative exploratory approach, interviews were conducted with 34 parents of children with epilepsy (aged 6-16 years), consisting of 27 mothers and 7 fathers. Data were transcribed verbatim and thematically analyzed. Findings revealed five main themes: normalizing epilepsy, the invisibility of epilepsy, information concealment, fear of misinforming the child, and difficulty in discussing particular epilepsy-related issues. Many of the communicative challenges experienced by parents impacted on their ability to engage openly in parent-child dialog about epilepsy in the home. Parents face specific challenges when choosing to communicate with their child about epilepsy, relating to creating a sense of normality, reducing fear of causing their child worry, and having a lack of epilepsy-related knowledge. Healthcare professionals who work closely with families living with epilepsy should remain mindful of the importance of discussing family communication surrounding epilepsy and the challenges parents of children with epilepsy face when talking about epilepsy within the home.

  17. Telerehabilitation Clinical and Vocational Applications for Assistive Technology: Research, Opportunities, and Challenges

    Directory of Open Access Journals (Sweden)

    Mark R. Schmeler

    2009-09-01

    Full Text Available Rehabilitation service providers in rural or underserved areas are often challenged in meeting the needs of their complex patients due to limited resources in their geographical area. Recruitment and retention of the rural clinical workforce are beset by the ongoing problems associated with limited continuing education opportunities, professional isolation, and the challenges inherent in coordinating rural community healthcare. People with disabilities who live in rural communities also face challenges accessing healthcare. Traveling long distances to a specialty clinic for necessary expertise may be troublesome due to inadequate or unavailable transportation, disability specific limitations, and financial limitations. Distance and lack of access are just two threats to quality of care that now being addressed by the use of videoconferencing, information exchange, and other telecommunication technologies that facilitate telerehabilitation. This white paper illustrates and summarizes clinical and vocational applications of telerehabilitation. We provide definitions related to the fields of telemedicine, telehealth, and telerehabilitation, and consider the impetus for telerehabilitation. We review the telerehabilitation literature for assistive technology applications; pressure ulcer prevention; virtual reality applications; speech-language pathology applications; seating and wheeled mobility applications; vocational rehabilitation applications; and cost effectiveness. We then discuss external telerehabilitation influencers, such as the positions of professional organizations. Finally, we summarize clinical and policy issues in a limited context appropriate to the scope of this paper. Keywords: Telerehabilitation, Telehealth, Telemedicine, Telepractice

    Background The current popularity of mindfulness-based practices has coincided with the increase in access to mobile technology. This has led to many mindfulness apps and programs becoming available, some specifically for children. However, little is known about the experience of engaging with mindfulness through these mediums. Aims To explore children's experience of mindfulness delivered both face-to-face and through a computer game to highlight any differences or similarities. Method A two-armed qualitative focus groups design was used to explore children's experiences. The first arm offered mindfulness exercises in a traditional face-to-face setting with guided meditations. The second arm offered mindfulness exercises through a computer game avatar. Results Themes of relaxation, engagement, awareness, thinking, practice and directing attention emerged from both arms of focus groups. Subthematic codes highlight key differences as well as similarities in the experience of mindfulness. Conclusions These results indicate that mindfulness delivered via technology can offer a rich experience. © The Royal College of Psychiatrists 2017.

  4. Facing up to 'challenging behaviour': a model for training in staff-client interaction.

    Science.gov (United States)

    Farrell, Gerald A; Shafiei, Touran; Salmon, Peter

    2010-07-01

    This paper draws on theory and evidence to develop a conceptual staff training model for the management of 'challenging behaviour'. Staff working with clients who are experienced as challenging commonly report negative feelings such as anxiety, anger, guilt, fear, self-blame and powerlessness, as well as dissatisfaction with their jobs. Current training programmes in challenging behaviour offer a 'smorgasbord' of content, without a clearly defined conceptual framework. Medline and PsychInfo were searched for papers in English from 1998 to 2008, linking 'nurs*' to 'challenging behavio*' and its related terms. Additional hand-searching identified informative papers from disciplines outside nursing older than the search period. We developed an applied model for training educators in respect of challenging behaviours. The model directs educators to consider: the influence of the nurse, including their values, emotional processes and behavioural skills; features of the client; and features of the situation in which the behaviour occurs, including its culture and working practices and physical environment. The most striking implication of the model is that it explicitly recognizes the importance of domains of learning other than skill. This enables educators to find educationally appropriate responses to resource limitations that inevitably constrain training. Challenging behaviour should be considered as a product of several intertwined factors: the actors involved - nurses, clients and others - and the situation in which the behaviour occurs, including its culture and working practices and physical environment.

  5. Soft Robotics: from scientific challenges to technological applications

    Science.gov (United States)

    Laschi, C.

    2016-05-01

    Soft robotics is a recent and rapidly growing field of research, which aims at unveiling the principles for building robots that include soft materials and compliance in the interaction with the environment, so as to exploit so-called embodied intelligence and negotiate natural environment more effectively. Using soft materials for building robots poses new technological challenges: the technologies for actuating soft materials, for embedding sensors into soft robot parts, for controlling soft robots are among the main ones. This is stimulating research in many disciplines and many countries, such that a wide community is gathering around initiatives like the IEEE TAS TC on Soft Robotics and the RoboSoft CA - A Coordination Action for Soft Robotics, funded by the European Commission. Though still in its early stages of development, soft robotics is finding its way in a variety of applications, where safe contact is a main issue, in the biomedical field, as well as in exploration tasks and in the manufacturing industry. And though the development of the enabling technologies is still a priority, a fruitful loop is growing between basic research and application-oriented research in soft robotics.

    1998-04-01

    The present study was designed to examine effects of closed-circuit technology on children's testimony and jurors' perceptions of child witnesses. For the study, a series of elaborately staged mock trials was held. First, 5- to 6-year-old and 8- to 9-year-old children individually participated in a play session with an unfamiliar male confederate. Approximately 2 weeks later, children individually testified about the event at downtown city courtroom. Mock juries composed of community recruits viewed the trials, with the child's testimony presented either live in open court or over closed-circuit television. Mock jurors made ratings concerning the child witness and the defendant, and deliberated to reach a verdict. Results indicated that overall, older children were more accurate witnesses than younger children. However, older, not younger children produced more inaccurate information in free recall. Compared to live testimony in open court, use of closed-circuit technology led to decreased suggestibility for younger children. Testifying in open court was also associated with children experiencing greater pretrial anxiety. Closed-circuit technology did not diminish fact finders' abilities to discriminate accurate from inaccurate child testimony, nor did it directly bias jurors against the defendant. However, closed-circuit testimony biased jurors against child witnesses. Moreover, jurors tended to base their impressions of witness credibility on perceived confidence and consistency. Implications for the use of closed-circuit technology when children testify are discussed.

    2013-01-01

    Context: Men entering the nursing profession have been investigated from several different perspectives. Due to male gender characteristics and existing public image, nursing is often not considered as a career choice by men. Whether nursing would benefit from increased number of men is a key question in the literature. The purpose of this integrative review of the literature was to identify factors influencing men to enter the nursing profession. In addition, it sought to understand the challenges they are confronted within this profession. Evidence Acquisition: A systematic search of the existing literature was performed using an Internet search with broad keywords to access related articles in both Persian and English databases. Finally, 34 studies (written between 2000 and early 2013) were selected and surveyed. Results: Most of the studies were conducted in developed counties. The review identified reasons why males choose nursing, and other challenges facing men entering and working in nursing. Themes that emerged from the literature include educational and societal barriers experienced by men in nursing, recruitment, career choice, and role strain. Conclusions: Regarding men’s influences on professional development, and also the importance of gender-based caring, policies for recruitment and retention of men in nursing must be followed hastily. However, there is a need for further research regarding the challenges faced by men entering nursing, in both Iran and other developing countries. PMID:25414879

    Macedonia, Christian; Zamisch, Monica; Judy, Jack; Ling, Geoffrey

    2012-06-01

    The repair of traumatic injuries to the central nervous system remains among the most challenging and exciting frontiers in medicine. In both traumatic brain injury and spinal cord injuries, the ultimate goals are to minimize damage and foster recovery. Numerous DARPA initiatives are in progress to meet these goals. The PREventing Violent Explosive Neurologic Trauma program focuses on the characterization of non-penetrating brain injuries resulting from explosive blast, devising predictive models and test platforms, and creating strategies for mitigation and treatment. To this end, animal models of blast induced brain injury are being established, including swine and non-human primates. Assessment of brain injury in blast injured humans will provide invaluable information on brain injury associated motor and cognitive dysfunctions. The Blast Gauge effort provided a device to measure warfighter's blast exposures which will contribute to diagnosing the level of brain injury. The program Cavitation as a Damage Mechanism for Traumatic Brain Injury from Explosive Blast developed mathematical models that predict stresses, strains, and cavitation induced from blast exposures, and is devising mitigation technologies to eliminate injuries resulting from cavitation. The Revolutionizing Prosthetics program is developing an avant-garde prosthetic arm that responds to direct neural control and provides sensory feedback through electrical stimulation. The Reliable Neural-Interface Technology effort will devise technologies to optimally extract information from the nervous system to control next generation prosthetic devices with high fidelity. The emerging knowledge and technologies arising from these DARPA programs will significantly improve the treatment of brain and spinal cord injured patients.

  13. How to overcome some of the challenges that African scholars are facing in conducting informetrics research

    Directory of Open Access Journals (Sweden)

    2011-01-01

    Full Text Available This article provides evidence to show that the contributions of African researchers to the informetrics literature are minimal. The three main challenges identified as limiting the contributions of African scholars to the informetrics literature are lack of appropriate skills, inadequate data collection sources, and unaffordable analytical tools. To overcome these challenges, it is suggested that regular pre-conference workshops on informetrics should be organized, an African Citation Index should be developed, and the use of free analytical tools should be encouraged.

    To qualitatively analyze free-text responses gathered as part of a previously published survey in order to systematically identify common concerns facing pharmacy experiential education (EE) programs. In 2011, EE directors at all 118 accredited pharmacy schools in the US were asked in a survey to describe the most pressing issues facing their programs. Investigators performed qualitative, thematic analysis of responses and compared results against demographic data (institution type, class size, number of practice sites, number and type of EE faculty member/staff). Expert and novice investigators identified common themes via an iterative process. To check validity, additional expert and novice reviewers independently coded responses. The Cohen kappa coefficient was calculated and showed good agreement between investigators and reviewers. Seventy-eight responses were received (66% response rate) representing 75% of publicly funded institutions and 71% of schools with class sizes 51-150. Themes identified as common concerns were site capacity, workload/financial support, quality assurance, preceptor development, preceptor stipends, assessment, onboarding, and support/recognition from administration. Good agreement (mean percent agreement 93%, ƙ range=0.59-0.92) was found between investigators and reviewers. Site capacity for student placements continues to be the foremost concern for many experiential education programs. New concerns about preceptor development and procedures for placing and orienting students at individual practice sites (ie, "onboarding") have emerged and must be addressed as new accreditation standards are implemented.

    The purpose of this article is to present the challenges for welding and hardfacing technology involved by sodium fast breeder reactors and by ASTRID specificities. To meet with compromises between achieving good ductility properties (toughness, impact, elongation…) and room/high temperature mechanical resistance (creep, strength…) in welds, as ensuring metallurgical (solidification cracking) and process weldability, the development of specific welding filler consumables for materials used in the creep conditions is needed. The developments deal with the candidate materials (316L(N), Grade 91) and integrate a qualification approach to aim at achiving a robust manufacturing. Contact zones in FBR sodium environment are subjected to various solicitations (high temperature, severe contact pressure, cycling…). When subjected to radiation, hardfacing alternatives to traditional cobalt base coatings depend on the application are required. The approach to evaluate the performance of alternative solutions, through an experimental program, will be presented. (author)

    2014-01-01

    This article investigates the circumstances in which Brazil’s sanitation reform was conceived and the Sistema Único de Saúde (SUS) was constructed. A brief analysis is conducted of Brazil’s political transition to democracy, focusing on three political challenges facing the consolidation of SUS: its weak support base amongst workers, competition with the private sector, and the fragmentation of its administration caused by its municipalization. Finally, the changes in the scenario caused by the weakening of neoliberalism since the 2008 crisis, the reemergence of a multipolar political scenario internationally, and the financing conditions of the Brazilian State are described.

    Full Text Available The complexities of navigating pregnancy while living with HIV predispose women to additional stress. Finding ways to minimize psychosocial challenges during the perinatal period may maximize the well-being of mothers living with HIV and their children. The goal of this study was to explore psychosocial challenges experienced by women living with HIV (WLWH during pregnancy and the postpartum. We conducted individual in-depth interviews with 20 WLWH recruited from an HIV treatment cohort study in Mbarara, Uganda as part of a larger study exploring perinatal depression. We conducted content analyses to identify themes related to challenges of WLWH during pregnancy and the postpartum. Participants had a median age of 33 years [IQR: 28-35], a median of 3 living children [IQR: 2-5], and 95% had achieved HIV-RNA suppression. Challenges were organized around the following themes: HIV -related stigma from health professionals, HIV status disclosure dilemma, unintended pregnancy and intimate partner violence, HIV and environmental structural barriers and distress and fear related to maternal and child health. Stigma centered on discrimination by health care professionals and personal shame associated with being pregnant as a WLWH. This led to difficulty engaging in HIV care, particularly when coupled with structural barriers, such as lack of transportation to clinic. Participants experienced intimate partner violence and lacked support from their partners and family members. Distress and fear about the health and uncertainty about the future of the unborn baby due to maternal deteriorating physical health was common. The perinatal period is a time of stress for WLWH. Challenges experienced by WLWH may compromise successful engagement in HIV care and may reduce quality of life for women and their children. Strategies aimed at alleviating the challenges of WLWH should involve the larger structural environment including partners, family and community member

    In every country concerned in radioactive waste management, the technicians thought they had possible solutions but they collided with a lack of understanding and came into conflict with public. What was demanded was a true policy control of scientific and technological choices as regard wastes. The decision to build a deep storage cannot be taken without a new law: the parliament will lean on a final report in 2006, which date a decision will be taken. Until this date, studies and research program are reviewed every year. (N.C.).

    2009-07-01

    The global energy requirement has grown at a phenomenon rate and the consumption of primary energy sources has been a very high positive growth. This paper focuses on the consumption of different primary energy sources and it identifies that coal will continue to remain as the prime energy source in foreseeable future. It examines the energy requirement perspective for India and demand of coal as the prime energy source. Economic development and poverty alleviation depend on securing affordable energy sources and Indian coal mining industry offers a bright future for the country's energy security, provided the industry is allowed to develop by supportive government policies and adopts latest technologies for mining. It is an irony that in-spite of having a plentiful reserves, India is not able to jack up coal production to meet its current and future demand. It discusses the strategies to be adopted for growth and meeting the coal demand. But such energy are very much concerned with environmental degradation and must be driven by contemporary managerial acumen addressing environmental and social challenges effectively The paper highlights the emissions of greenhouse gases due to burning of fossil fuels and environmental consequences of global warming and sea-level rise. Technological solutions for environment friendly coal mining and environmental laws for the abatement of environmental degradation are discussed in this paper.

    Mattsson, Mats-Olof; Simkó, Myrtill

    2017-03-01

    Risk assessment (RA) of manufactured nanomaterials (MNM) is essential for regulatory purposes and risk management activities. Similar to RA of "classical" chemicals, MNM RA requires knowledge about exposure as well as of hazard potential and dose response relationships. What makes MNM RA especially challenging is the multitude of materials (which is expected to increase substantially in the future), the complexity of MNM value chains and life cycles, the accompanying possible changes in material properties over time and in contact with various environmental and organismal milieus, and the difficulties to obtain proper exposure data and to consider the proper dose metric. This article discusses these challenges and also critically overviews the current state of the art regarding MNM RA approaches. Copyright © 2016 Elsevier Inc. All rights reserved.

    2013-06-01

    Biotechnological and life science innovations do not only lead to immense progress in diverse fields of natural science and technical research and thereby drive economic development, they also fundamentally affect the relationship between nature, technology and society. Taken this seriously, the ethical and societal assessment of emerging biotechnologies as for example synthetic biology is challenged not only to constrain on questions of biosafety and biosecurity but also to face the societal questions within the different fields as an interface problem of science and society. In order to map this vague and stirring field, we propose the concept of bio-objects to explore the reciprocal interaction at the interface of science and society serious as well to have the opportunity to detect possible junctions of societal discontent and unease before their appearance.

    Full Text Available This article explores the academic and social challenges experienced by students from the gay, lesbian, bisexual and transgender (glbt community on campus at a South African university. A qualitative study to investigate some of these academic and social challenges experienced by glbt students at a university campus was conducted. The population of the study was all students from glbt community on campus and a purposive sample of twelve (12 respondents was constituted and a semi-structured interview guide was designed and administered to all twelve (12 participants. Data were audio recorded and transcribed. Content analysis which is a method used to systematically analyse the meaning of communications was used to analyse data. Of central interest were the core themes that speakers referred to, the information or messages that they wanted to pass on to their audience. The findings suggest that glbt students grapple with issues such as labelling, sexual abuse, discrimination/marginalisation and unfairness in the allocation of resources such as accommodation. In response to these cancerous societal ills, the helping professions exhort practitioners to empower vulnerable populations, promote social justice, support client self-determination and keep abreast of current knowledge relevant to professional practice. This article concludes with a set of recommendations on some of the strategies to address the identified socio-academic challenges.

    2017-12-27

    With the advent of flexible electronics, lithium-ion batteries have become a key component of high performance energy storage systems. Thus, considerable effort is made to keep up with the development of flexible lithium-ion batteries. To date, many researchers have studied newly designed batteries with flexibility, however, there are several significant challenges that need to be overcome, such as degradation of electrodes under external load, poor battery performance, and complicated cell preparation procedures. In addition, an in-depth understanding of the current challenges for flexible batteries is rarely addressed in a systematical and practical way. Herein, recent progress and current issues of flexible lithium-ion batteries in terms of battery materials and cell designs are reviewed. A critical overview of important issues and challenges for the practical application of flexible lithium-ion batteries is also provided. Finally, the strategies are discussed to overcome current limitations of the practical use of flexible lithium-based batteries, providing a direction for future research. © 2017 WILEY-VCH Verlag GmbH & Co.

  7. 21st century challenges faced by nursing faculty in educating for compassionate practice: embodied interpretation of phenomenological data.

    Science.gov (United States)

    Curtis, Katherine

    2013-07-01

    Nursing faculty are facing challenges in facilitating student learning of complex concepts such as compassionate practice. Compassion is a stated expectation of Registered Nurse (RN) and student nurse practice, and yet how it is enabled and learned within the challenging environments of university and health service provider organisations are not yet understood. There is currently an international concern that student nurses are not being adequately prepared for compassion to flourish and for compassionate practice to be sustained upon professional qualification. In order to investigate the experiences of nursing faculty in their preparation of student nurses for compassionate practice, an exploratory aesthetic phenomenological research study was undertaken using in depth interviews with five nurse teachers in the North of England. Findings from this study were analysed and presented using embodied interpretation, and indicate that nurse teachers recognise the importance of the professional ideal of compassionate practice alongside specific challenges this expectation presents. They have concerns about how the economically constrained and target driven practice reality faced by RNs promotes compassionate practice, and that students are left feeling vulnerable to dissonance between learned professional ideals and the RNs' practice reality they witness. Nurse teachers also experience dissonance within the university setting, between the pressures of managing large student groups and the time and opportunity required for small group discussion with students that enables compassion to develop in a meaningful and emotionally sustainable way. Teachers also express discomfort due to a perceived promotion of an 'unachievable utopia' within practice, identifying how the constraints within practice could be better managed to support professional ideals. The nurse teachers within this exploratory study identify the need for strong nurse leadership in practice to challenge

    Demand for healthcare services is unprecedented. Society is struggling to afford the cost. Pricing of biopharmaceutical products is under scrutiny, especially by payers and Health Technology Assessment agencies. As we discuss here, rapidly advancing technologies, such as Real-World Data (RWD), are being utilized to increase understanding of disease. RWD, when captured and analyzed, produces the Real-World Evidence (RWE) that underpins the economic case for innovative medicines. Furthermore, RWD can inform the understanding of disease, help identify new therapeutic intervention points, and improve the efficiency of research and development (R&D), especially clinical trials. Pursuing precompetitive collaborations to define shared requirements for the use of RWD would equip service-providers with the specifications needed to implement cloud-based solutions for RWD acquisition, management and analysis. Only this approach would deliver cost-effective solutions to an industry-wide problem. Copyright © 2018 Elsevier Ltd. All rights reserved.

    Hankir, Ahmed; Carrick, Frederick R; Zaman, Rashid

    2017-09-01

    The rise of radicalisation, the 'demonization' of Muslims in the media and the immigration crisis in Europe have all contributed and colluded to heightened levels of Islamophobia in the West. The stigmatisation of Muslims can and has resulted in negative outcomes in this group such as elevated levels of psychological distress and an increase in hate crime and terrorist attacks perpetrated against Muslims from members of the far right. There are 1.6 billion Muslims on the planet and Islam is the fastest growing religion in the world. Now, more than ever it seems, is a critical time to learn about what the true message of Islam is and who the blessed prophet Muhammad peace be upon him (PBUH) was from reliable and authentic sources. This paper aims to challenge the stigma attached to Muslims through the following means: 1. It contains information to educate people about Islam, debunk myths and challenge negative stereotypes; 2. It utilizes the power of 'story-telling' to engage readers and to equip them with facts and the necessary skills to combat Islamophobia. Part I includes a brief introduction of Islam and concludes with a concise description and evaluation of an anti-Islamophobia programme that was piloted in Cambridge University (UK) and delivered as a Keynote Address at the Carrick Institute for Graduate Studies International Symposium of Clinical Neuroscience in Orlando, (USA). Our hope is that through this initiative we can create a critical mass and inspire and empower people, Muslims and non-Muslims alike to stand in solidarity and collectively challenge extremism in any of its many forms. Our hypothesis is that this will result in better outcomes such as reductions in radicalization and Islamophobia.

    2002-01-01

    The state of Kansas' implementation of a privatized child welfare system is arguably an ambitious shift in child welfare service delivery. In an attempt to drastically improve services to vulnerable families, privatization resulted in intended and unintended consequences for the child welfare workforce. Some of these consequences, including the influx of inexperienced new workers, high worker turnover, and managing relationships with multiple partners, are issues that affect training needs of child welfare professionals. The following paper offers one approach to addressing these needs as well as identifying the challenges involved in training in a privatized environment.

    Data about patients are available from diverse sources, including those routinely collected as individuals interact with service providers, and those provided directly by individuals through surveys. Linking these data can lead to a more complete picture about the individual, to inform either care decision making or research investigations. However, post-linkage, differences in data recording systems and formats present barriers to achieving these aims. This paper describes an approach to combine linked GP records with study observations, and reports initial challenges related to semantic and syntactic interoperability issues.

    Several challenges make it difficult to simultaneously investigate central and autonomous nervous system correlates of conditioned stimulus (CS) processing in classical conditioning paradigms. Such challenges include, for example, the discrepant requirements of electroencephalography (EEG) and electrodermal activity (EDA) recordings with regard to multiple repetitions of conditions and sufficient trial duration. Here, we propose a MultiCS conditioning set-up, in which we increased the number of CSs, decreased the number of learning trials, and used trials of short and long durations for meeting requirements of simultaneous EEG–EDA recording in a differential aversive conditioning task. Forty-eight participants underwent MultiCS conditioning, in which four neutral faces (CS+) were paired four times each with aversive electric stimulation (unconditioned stimulus) during acquisition, while four different neutral faces (CS−) remained unpaired. When comparing after relative to before learning measurements, EEG revealed an enhanced centro-posterior positivity to CS+ vs. CS− during 368–600 ms, and subjective ratings indicated CS+ to be less pleasant and more arousing than CS−. Furthermore, changes in CS valence and arousal were strong enough to bias subjective ratings when faces of CS+/CS− identity were displayed with different emotional expression (happy, angry) in a post-experimental behavioral task. In contrast to a persistent neural and evaluative CS+/CS− differentiation that sustained multiple unreinforced CS presentations, electrodermal differentiation was rapidly extinguished. Current results suggest that MultiCS conditioning provides a promising paradigm for investigating pre–post-learning changes under minimal influences of extinction and overlearning of simple stimulus features. Our data also revealed methodological pitfalls, such as the possibility of occurring artifacts when combining different acquisition systems for central and peripheral

  17. A low carbon industrial revolution? Insights and challenges from past technological and economic transformations

    International Nuclear Information System (INIS)

    Pearson, Peter J.G.; Foxon, Timothy J.

    2012-01-01

    Recent efforts to promote a transition to a low carbon economy have been influenced by suggestions that a low carbon transition offers challenges and might yield economic benefits comparable to those of the previous industrial revolutions. This paper examines these arguments and the challenges facing a low carbon transition, by drawing on recent thinking on the technological, economic and institutional factors that enabled and sustained the first (British) industrial revolution, and the role of ‘general purpose technologies’ in stimulating and sustaining this and subsequent industrial transformation processes that have contributed to significant macroeconomic gains. These revolutions involved profound, long drawn-out changes in economy, technology and society; and although their energy transitions led to long-run economic benefits, they took many decades to develop. To reap significant long-run economic benefits from a low carbon transition sooner rather than later would require systemic efforts and incentives for low carbon innovation and substitution of high-carbon technologies. We conclude that while achieving a low carbon transition may require societal changes on a scale comparable with those of previous industrial revolutions, this transition does not yet resemble previous industrial revolutions. A successful low carbon transition would, however, amount to a different kind of industrial revolution. - Highlights: ► Investigates lessons for a low carbon transition from past industrial revolutions. ► Explores the implications of ‘general purpose technologies’ and their properties. ► Examines analysis of ‘long waves’ of technological progress and diffusion. ► Draws insights for low carbon transitions and policy.

    51 of the satisfactory group. Photographic analysis of pre- and post-treatment digital images did not yield statistically significant results. Our study adds the growing body of information on this new device. Radiofrequency causes movement of charged particles within the tissue, and the resultant molecular motion generates heat. The heat in turn causes collagen shrinkage and new collagen deposition. Based on our findings, younger patients tend to respond better. This is not surprising, since heat-labile collagen bonds are progressively replaced by irreducible multivalent cross-links as the tissue ages. Second, higher dial settings and corresponding higher energy per pulse correlated with better response. Third, those who had the entire surface area of the face and neck treated tend to do better than those with partial treatment. The data from the study give us critical clues in refining this exciting new technology for cosmetic uses and beyond.

  19. Establishing a Conceptual Foundation for Addressing Challenges Facing Food-Energy-Water Management

    Goldsby, M.; Padowski, J.; Katz, S.; Brady, M.; Hampton, S. E.

    2017-12-01

    Ensuring the security of food, energy and water in the face of a changing environment is a top societal priority. In order to make sound policy decisions aimed at meeting those needs, policy-makers need decision-relevant information. As such, considerable effort and resources have recently been devoted to investigating the Food-Energy-Water (FEW) Nexus in order to better provide that information. However, despite the increased research activity into FEW systems and FEW problems, little attention has been devoted to the fundamental conceptual issues underlying contemporary FEW systems. Consequently, this inattention has led to conceptual confusion about what is and what is not a FEW system. This project aims to fill that lacuna in order to better facilitate the FEW research agenda. Toward that end, we identify three features that distinguish FEW problems from other resource management problems: (1) the production and management of the resources in each sector of a FEW system is specialized to its own sector; (2) interdependencies exist between sectors such that overproduction in one sector, for example, may have impacts on other sectors; and (3) there are real limits to FEW resource availability as well as limits on the ability to transact across sector boundaries. We contend that once armed with this distinction, one can model the stocks and flows of FEW capital in a conceptually rigorous way that may lead to operational innovations of FEW management.

    Full Text Available Apart from the financial risk the insurance industry are facing with in association with climate change, there are also opportun ities to the sector to develop new markets and provide coverage against weather related risks. This study presents a possible method to examine the potential for introducing a new insurance product, namely an agricultural flood insurance scheme in the United Kingdom. The investigation included the calculation of agricultural flood damage costs, the possible changes in flood risk, the description of farmers’ risk attitude and interests in insurance. In a small scale survey, farmers were asked their experiences related to flooding, farm management practices and thei r willingness to pay for flood insurance using a contingent valuation method. Using statistical analysis it was found the insurance demand is positively correlated with the damage cost predicted and association is likely between farm types and WTP for insurance. Linear regression model suggests that the demand for flood insurance is low amongst farmers in the present risk level. The findi ngs of this research highlight that there is little evidence for the viability of a farmer financed agricultural flood insurance scheme at the moment in the United Kingdom.

    Community health worker (CHW) programs are implemented in many low- and middle-income countries such as Brazil to increase access to and quality of care for underserved populations; CHW programs have been found to improve certain indicators of health, but few studies have investigated the daily work of CHWs, their perspectives on what both helps and hinders them from fulfilling their roles, and ways that their effectiveness and job satisfaction could be increased. To examine these questions, we observed clinic visits, CHW home visits, and conducted semistructured interviews with CHWs in 7 primary care centers in Brazil-2 in Salvador, Bahia, and 5 in São Paulo, SP-in which CHWs are incorporated into the work of all primary care health teams. In addition to enhancing communication between the medical system and the community, CHWs consider their key roles to be helping persuade community members to seek medical care and increasing health professionals' awareness of the social conditions affecting their patients' health. Key obstacles that CHWs face include failure to be fully integrated into the primary care team, inability to follow-up on identified health needs due to limited resources, as well as community members' lack of understanding of their work and undervaluing of preventative medicine. Increased training, better incorporation of CHWs into clinic flow and decision making, and establishing a clear community awareness of the roles and value of CHWs will help increase the motivation and effectiveness of CHWs in Brazil.

    The introduction of antiretroviral therapy (ART) for HIV infection in sub-Saharan Africa has improved the quality of life of millions of people and reduced mortality. However, substantial problems with the infrastructure for ART delivery remain. Clinicians and researchers at an HIV clinic in Guinea-Bissau identified problems with the delivery of ART by establishing a clinical database and by collaborating with international researchers. The Bissau HIV cohort study group was established in 2007 as a collaboration between local HIV physicians and international HIV researchers. Patients were recruited from the HIV clinic at the country's main hospital in the capital Bissau. Between 2005 and 2013, 5514 HIV-positive patients were treated at the clinic. Working together, local health-care workers and international researchers identified the main problems affecting ART delivery: inadequate drug supply; loss of patients to follow-up; and inadequate laboratory services. Solutions to these problems were devised. The collaborations encouraged local physicians to start their own research projects to find possible solutions to problems at the clinic. The HIV clinic in Bissau faced numerous obstacles in delivering ART at a sufficiently high quality and patients' lives were put in jeopardy. The effectiveness of ART could be enhanced by delivering it as part of an international research collaboration since such collaborations can help identify problems, find solutions and increase the capacity of the health-care system.

    This report identifies underlying economic and electricity market factors that have led to early retirements of U.S. operating nuclear power plants, assesses the Gap between operating revenues and operating costs for selected nuclear power plants, and discusses a range of actions that might be taken to stop early retirement of operating nuclear power plants. The Kewaunee and Vermont Yankee nuclear power plants were retired early for economic and financial reasons. Early retirement has been announced or proposed for Clinton and Quad Cities in Illinois, Fitzpatrick and Ginna in New York, Fort Calhoun in Nebraska. Other nuclear power plants, including Palisades, Davis-Besse, Prairie Island, and Three Mile Island Unit 1, have been identified as facing financial stress that might lead to early retirement. The early retirement of operating nuclear power plants will mean the loss of a large amount of zero-emission electricity, inconsistent with the goal of reducing carbon emissions in the electricity sector. This report provides a high-level view of the major factors driving early retirement: • The U.S. market and private ownership approach to the electricity sector; • Low electricity market prices resulting from low natural gas prices, low demand growth, increased penetration of renewable generation, and negative electricity market prices; and • No compensation to nuclear power plants for public benefits including zero-emission electricity.

    Full Text Available This paper analyzes weaknesses faced by the carbon neutrality initiative proposed by the Costa Rican government due to metrics and highlights some of the technical improvements that will be required in order to achieve greater comparability, applicability and confidence from the results obtained. Technical gaps are found not only in the assessment of greenhouse gas emissions but when accounting for biogenic carbon capture and storage, where global reference values, usually those reported by the IPCC, are commonly used. We then make reference to problems associated with their use, mainly related to the uncertainty (accuracy and precision that results from any estimate. At the national level there is a lack of information for biomass and carbon for some ecosystems as well as few complete studies that consider all carbon pools at the ecosystem level. We give examples for some of the most studied species. Finally, we compare results using global reference values against those developed from local studies a the national level.

  5. A Cross-Cultural Perspective on Challenges Facing Comparative Cancer Survivorship Research

    2011-01-01

    Cancer survivorship research includes the study of physical, psychosocial, and economic consequences of cancer diagnosis and treatment among pediatric and adult cancer survivors. Historically, the majority of cancer survivorship studies were from the United States, but survivorship issues are increasingly being addressed in other developed countries. Cross-cultural studies remain, however, scarce. The degree to which knowledge attained may or may not be transferred across cultures, countries, or regions is not known. Some important challenges for comparative research are therefore discussed in a cross-cultural perspective. Several substantive and methodological challenges that complicate the execution of cross-cultural cancer survivorship research are presented with examples and discussed to facilitate comparative research efforts in the establishment of new survivorship cohorts and in the planning and implementation of survivorship studies. Comparative research is one key to understanding the nature of cancer survivorship, distinguishing modifiable from non modifiable factors at individual, hospital, societal, and system levels and may thus guide appropriate interventions. Lastly, suggested future courses of action within the field of comparative cancer survivorship research are provided.

    2009-09-01

    Full Text Available Chemicals have become the backbone of manufacturing within industrialized economies. Being energy-intensive materials to produce, this sector is threatened by policies aimed at combating and adapting to climate change. This study examines the worst-case scenario for the U.S. chemicals industry when a medium CO2 price policy is employed. After examining possible industry responses, the study goes on to identify and provide a preliminary evaluation of potential opportunities to mitigate these impacts. If climate regulations are applied only in the United States, and no action is taken to invest in advanced low- and no-carbon technologies to mitigate the impacts of rising energy costs, the examination shows that climate policies that put a price on carbon could have substantial impacts on the competiveness of the U.S. chemicals industry over the next two decades. In the long run, there exist technologies that are available to enable the chemicals sector to achieve sufficient efficiency gains to offset and manage the additional energy costs arising from a climate policy.

    Directory of Open Access Journals (Sweden)

    Rodrigo José Teixeira

    2017-12-01

    Full Text Available This article offers an analysis of the intrinsic relationship between the social question and Social Work. The analysis of the social question starts from the meticulous and rigorous reading of the labor theory of value and the Critique of Political Economy written by Karl Marx. It is from this analysis that we try to justify the genesis of the profession linked to the role of the state and the bourgeoisie in the consolidation of monopoly capitalism. It starts from the analysis of Social Work as a profession inserted in the social and technical division of labor that by its own action, in the contradictory movement of the capitalist reality, defends the interests of capital and labor. In addition, the article presents, in a succinct way, the trajectory of Social Work in Brazil and its ethical and political project in relation to the working class challenges to guarantee this direction in times of dismantling social policies and financial capitalism.

    2012-05-01

    Full Text Available This article reports on a 2008 study of non-indigenous principals working in indigenous Yukon contexts. It examines the policy contexts in which Yukon principals are embedded, giving attention to how they address the tensions that exist as a result of operating at the intersections of multiple policy levels. The application of critical ethnography generates the opportunity to reveal and examine the tensions, distinctions, and contradictions underpinning their practice. The principals identify fragmented curricular policy; the competition between instructional time, mandated external curricula, and locally developed curricula; and field trip and hiring policies as being problematic. The principals also describe how they cope with the challenges and tensions that arise as a result of being responsible and accountable to balance competing educational ends, to the satisfaction of multiple external levels of control. The study calls for a re-evaluation of the deployment of externally mandated curricula in the Yukon.

    2012-03-01

    Full Text Available Many kinds of entities—including terrorists and insurgents—seek to influence perceptions and behavior among various target audiences, and have become increasingly reliant on the Internet in their efforts, incorporating social media, blogging, public video sharing and other online tools. This article is focused on the ideological messages that terrorist groups use to convey with these tools. Drawing from a study of Al-Qaeda, this discussion illustrates how ideologies of violence have certain vulnerabilities that can be exploited in order to degrade a terrorist group’s ability to achieve its objectives. While crafting and disseminating counter-narratives can be a critical part of a counterterrorism strategy, it is also important to identify ways in which terrorists undermine their own central narratives and exacerbate pre-existing “influence warfare” challenges

    The farm animal veterinary profession in the UK has faced a number of challenges in recent decades related to the withdrawal of government funding and a contraction of the agricultural sector. They have come under pressure to respond by developing skills and focusing on disease prevention advisory services. However, this puts veterinarians in competition with other providers of these services, and moves in this direction have only been partial. Failure to respond to these challenges puts the veterinary profession at risk of de-professionalisation-a loss of their monopoly over knowledge, an erosion of client beliefs in their service ethos and a loss of work autonomy. This paper explores how farm animal veterinarians in England perceive these challenges and are responding to them. Semi-structured qualitative interviews were carried out with 28 veterinarians from Royal College of Veterinary Surgeon farm accredited practices. Veterinarians were chosen from high, medium and low density cattle farming regions. Interviews were recorded, transcribed and themes identified through the constant comparison method. The majority of respondents recognised the challenges facing the veterinary profession. Most believed their role had changed, moving towards that of a disease prevention adviser who was part of the farm management team. In terms of maintaining and redefining their professional status, farm animal veterinarians do have a defined body of knowledge and the ability to develop trusting relationships with clients, which enhances their competitiveness. However, while they recognise the changes and challenges, moves towards a disease prevention advisory model have only been partial. There seem to be little effort towards using Farm accreditation status or other strategies to promote their services. They do not appear to be finding effective strategies for putting their knowledge on disease prevention into practice. Disease prevention appears to be delivered on farm on an ad

    Full Text Available doi: http://dx.doi.org/10.15447/sfews.2015v13iss3art7Freshwater is a scarce and precious resource in California; its overall value is being made clear by the current severe drought. The Sacramento–San Joaquin Delta is a critical node in a complex water supply system that extends throughout much of the western U.S. wherein demand is exceeding supply. The Delta also underpins a major component of the U.S. economy, helps feed a substantial part of the country, is a unique and valuable ecological resource, and is a place with a rich cultural heritage. Sustaining the Delta is a problem that manifests itself in many dimensions including the physical structure of the Delta, the conflicting demands for water, changing water quality, rapidly evolving ecological character, and high institutional complexity. The problems of the California Delta are increasingly complex, sometimes chaotic, and always contentious. There is general agreement that current management will sustain neither the Delta ecosystem nor high-quality water exports, as required under the Delta Reform Act, so there is a renewed urgency to address all dimensions of the problem aggressively. Sustainable management of the Delta ecosystem and California’s highly variable water supply, in the face of global climate change, will require bold political decisions that include adjustments to the infrastructure but give equal emphasis to chronic overuse and misuse of water, promote enhanced efficiency of water use, and facilitate new initiatives for ecosystem recovery. This new approach will need to be underpinned by collaborative science that supports ongoing evaluation and re-adjustment of actions. Problems like the Delta are formally “wicked" problems that cannot be “solved” in the traditional sense, but they can be managed with appropriate knowledge and flexible institutions. Where possible, it is advisable to approach major actions incrementally, with an eye toward avoiding

    In order for the U.S. Geological Survey (USGS) to respond to evolving national and global priorities, it must periodically reflect on, and optimize, its strategic directions. This report is the first comprehensive science strategy since the early 1990s to examine critically major USGS science goals and priorities. The development of this science strategy comes at a time of global trends and rapidly evolving societal needs that pose important natural-science challenges. The emergence of a global economy affects the demand for all resources. The last decade has witnessed the emergence of a new model for managing Federal lands-ecosystem-based management. The U.S. Climate Change Science Program predicts that the next few decades will see rapid changes in the Nation's and the Earth's environment. Finally, the natural environment continues to pose risks to society in the form of volcanoes, earthquakes, wildland fires, floods, droughts, invasive species, variable and changing climate, and natural and anthropogenic toxins, as well as animal-borne diseases that affect humans. The use of, and competition for, natural resources on the global scale, and natural threats to those resources, has the potential to impact the Nation's ability to sustain its economy, national security, quality of life, and natural environment. Responding to these national priorities and global trends requires a science strategy that not only builds on existing USGS strengths and partnerships but also demands the innovation made possible by integrating the full breadth and depth of USGS capabilities. The USGS chooses to go forward in the science directions proposed here because the societal issues addressed by these science directions represent major challenges for the Nation's future and for the stewards of Federal lands, both onshore and offshore. The six science directions proposed in this science strategy are listed as follows. The ecosystems strategy is listed first because it has a dual nature

    2012-07-01

    Rapid progress in several high-tech industries has significantly increased the need for dimensional micro- and nano-metrology. Structures to be measured are becoming more complex with smaller structure widths and higher aspect ratios in increasingly larger surface regions and potentially highly curved surfaces. Significant international effort can be seen to develop high-capacity measuring machines with nanometre precision in growing measuring ranges up to hundreds of millimetres. This paper begins with an outline of the requirements stemming from high-tech developments currently being done or expected in the future and discusses recent developments in the field of nanopositioning and nanomeasuring technology with respect to basic measurement approaches, laser interferometer systems. The large range of nanoprobe systems usable in nanomeasuring machines is discussed, such as optical focus sensors, white light interferometer microscopes, CCD camera microscopes using the depth from the focus method, tactile stylus probes, atomic force microscopes (AFMs) and 3D microprobes. The versatile properties of these sensors allow the machine to be used in many different metrological applications. The paper also introduces a multi-sensor approach using a microscope revolver. It concludes with an illustration of metrologically challenging measurements, e.g., scanning micro-structures of curved optical surfaces or performing AFM scans of very large regions with significant data volume.

    Nuclear fission and nuclear safeguards have much in common, including the basic physical phenomena and technologies involved as well as the commitments and challenges posed by expanding nuclear programs in many countries around the world. The unique characteristics of the fission process -- such as prompt and delayed neutron and gamma ray emission -- not only provide the means of sustaining and controlling the fission chain reaction, but also provide unique ''signatures'' that are essential to quantitative measurement and effective safeguarding of key nuclear materials (notably 239 Pu and 235 U) against theft, loss, or diversion. In this paper, we trace briefly the historical emergence of safeguards as an essential component of the expansion of the nuclear enterprise worldwide. We then survey the major categories of passive and active nondestructive assay techniques that are currently in use or under development for rapid, accurate measurement and verification of safe-guarded nuclear materials in the many forms in which they occur throughout the nuclear fuel cycle. 23 refs., 14 figs

    To report the experience of health workers who had played key roles in the early stages of implementing the prevention of mother-to-child HIV transmission services (PMTCT) in Uganda. Interviews were conducted with 15 key informants including counsellors, obstetricians and PMTCT coordinators at the five PMTCT test sites in Uganda to investigate the benefits, challenges and sustainability of the PMTCT programme. Audio-taped interviews were held with each informant between January and June 2003. These were transcribed verbatim and manually analysed using the framework approach. The perceived benefits reported by informants were improvement of general obstetric care, provision of antiretroviral prophylaxis for HIV-positive mothers, staff training and community awareness. The main challenges lay in the reluctance of women to be tested for HIV, incomplete follow-up of participants, non-disclosure of HIV status and difficulties with infant feeding for HIV-positive mothers. Key informants thought that the programme's sustainability depended on maintaining staff morale and numbers, on improving services and providing more resources, particularly antiretroviral therapy for the HIV-positive women and their families. Uganda's experience in piloting the PMTCT programme reflected the many challenges faced by health workers. Potentially resource-sparing strategies such as the 'opt-out' approach to HIV testing required further evaluation.

    Climate change effects have the potential of affecting both ocean and atmospheric processes. These changes pose serious threats to the millions of people that live by the coast. Thus, the objective of the present review is to discuss how climate change is altering (and will continue to alter) atmospheric and oceanic processes, what are the main implications of these alterations along the coastline, and which are the ecosystem-based management (EBM) strategies that have been proposed and applied to address these issues. While ocean warming, ocean acidification and increasing sea level have been more extensively studied, investigations on the effects of climate change to wind and wave climates are less frequent. Coastal ecosystems and their respective natural resources will respond differently according to location, environmental drivers and coastal processes. EBM strategies have mostly concentrated on improving ecosystem services, which can be used to assist in mitigating climate change effects. The main challenge for developing nations regards gaps in information and scarcity of resources. Thus, for effective management and adaptive EBM strategies to be developed worldwide, information at a local level is greatly needed. Copyright © 2018 Elsevier Ltd. All rights reserved.

    The discourse of leaderism in health care has been a subject of much academic and practical debate. Recently, distributed leadership (DL) has been adopted as a key strand of policy in the UK National Health Service (NHS). However, there is some confusion over the meaning of DL and uncertainty over its application to clinical and non-clinical staff. This article examines the potential for DL in the NHS by drawing on qualitative data from three co-located health-care organisations that embraced DL as part of their organisational strategy. Recent theorising positions DL as a hybrid model combining focused and dispersed leadership; however, our data raise important challenges for policymakers and senior managers who are implementing such a leadership policy. We show that there are three distinct forms of disconnect and that these pose a significant problem for DL. However, we argue that instead of these disconnects posing a significant problem for the discourse of leaderism, they enable a fantasy of leadership that draws on and supports the discourse. © 2014 The Authors.

    Full Text Available Despite a record-breaking 14.5 per cent increase in world merchandise exports, the effects of the financial crisis and global recession are still hampering faster economic recovery. Relatively high oil prices combined with persistent unemployment and measures designed to reduce budget deficits have undermined short-term growth prospects. While South–South trade continues to explode, trade imbalances – i.e. the gap between exports and imports – widened in 2010 compared to 2009 (though smaller than pre-crisis levels. Meanwhile, trade negotiations under the Doha Round have reached an impasse, generating uncertainties about the future of the World Trade Organization (WTO as a negotiating forum. Under these circumstances, should the system rethink its decision-making process founded upon the predominance of member states, the principle of consensus and the notion of single undertaking, as some critics have suggested? And, if so, how could such a reform agenda be initiated at the WTO? Moreover, beyond the negotiating function of the WTO, the paralysis of the system also raises urgent questions about the ability of the system to respond to pressing challenges of our times, such as trade and climate change, or food security and price volatility.

    Advances in medicine have increased the life expectancy resulting in an increase in the geriatric population all over the world, and their proportion will only continue to rise in the coming years. It is known that the elderly bear a significant burden of morbidity, which is why health systems globally spearheaded by the WHO are waking up to the need for better geriatric health services. This includes India, whose health system continues to grapple with the health challenges of communicable and noncommunicable diseases. This article enumerates the various government policies and programs, constitutional and legal provisions available for the care of the elderly, and concludes that they are grossly inadequate to deal with the various physical, psychological, and emotional needs of the aging population. Mainstreaming of geriatric health to address the health needs of the elderly at all levels of health care, both in the public and the private sectors, giving due importance to multidimensional rehabilitative services and terminal care, involving NGOs and voluntary organizations, and stepping up social security in old age are the recommended measures for improving geriatric health in India.

    This review integrates historical developments and key events in bringing ethics into epidemiology in general and into environmental epidemiology in particular. The goal is to provide context for and discern among the various approaches and motivations that drive the need for ethical conduct in support of the public interest. The need for ethics guidelines in epidemiology is different from developments in other biomedical-related fields by virtue of its focus on populations rather than on individuals. The need for ethics guidelines in environmental epidemiology as a subspecialty of epidemiology stems from the larger scale of its mission than that of epidemiology per se. Ethics guidelines in the field of environmental epidemiology have been established. They articulate not only the profession's core values and mission, but more specifically, they address the environmental epidemiologist's obligations to the participants in research, to colleagues, and to employers. They are the product of consensus, scholarship, and diligent stewardship over several decades. The next challenge is ensuring their value and impact. The forces that support professional and institutional success, and the power of special interests, are the major threats to achieving the goals of ethical conduct and research for the public good. In environmental epidemiology, these threats have global implications.

    Along the United States–Mexican border, the health of communities, economies, and ecosystems is inextricably intertwined with the availability and quality of water, but effective water management in the Borderlands is complicated. Water users compete for resources, and their needs are increasing. Managers are faced with issues such as finding a balance between agriculture and rapidly growing cities or maintaining public supplies while ensuring sufficient resources for aquatic ecosystems. In addition to human factors, the dry climate of the Borderlands, as compared to more temperate regions, also increases the challenge of balancing water supplies between humans and ecosystems. Warmer, drier, and more variable conditions across the southwestern United States—the projected results of climate change (Seager and others, 2007)—would further stress water supplies.

    During the past decade, Taiwan has experienced an unusual and fast growing in the industry of mapping, remote sensing, spatial information and related markets. A successful space program and dozens of advanced airborne and ground-based remote sensing instruments as well as mobile mapping systems have been implemented and put into operation to support the vast demands of geospatial data acquisition. Moreover, in addition to the government agencies and research institutes, there are also tens of companies in the private sector providing geo-spatial data and services. However, the fast developing industry is also posing a great challenge to the education sector in Taiwan, especially the higher education for geo-spatial information. Facing this fast developing industry, the demands of skilled professionals and new technologies in order to address diversified needs are indubitably high. Consequently, while delighting in the expanding and prospering benefitted from the fast growing industry, how to fulfill these demands has become a challenge for the remote sensing and spatial information disciplines in the higher education institutes in Taiwan. This paper provides a brief insight into the status of the remote sensing and spatial information industry in Taiwan as well as the challenges of the education and technology transfer to support the increasing demands and to ensure the continuous development of the industry. In addition to the report of the current status of the remote sensing and spatial information related courses and programs in the colleges and universities, current and potential threatening issues and possible resolutions are also discussed in different points of view.

    Full Text Available With broad distributions, diadromous fishes can be exposed to multiple threats at different stages of development. For the primarily catadromous eels of the family Anguillidae, there is growing international concern for the population abundance and escapement trends of some of these species and yet incomplete knowledge of their remarkable life-histories hampers management and conservation. Anguillids experience a suite of pressures that include habitat loss/modification, migration barriers, pollution, parasitism, exploitation, and fluctuating oceanic conditions that likely have synergistic and regionally variable impacts, even within species. In beginning to redress this rather fragmented picture, we evaluated the extinction risk of these species using the IUCN Red List of Threatened Species Categories and Criteria to infer population-wide trends from catch and monitoring data. Here we consolidate and build upon these species assessments by presenting an overview of the current state of global eel data and conservation, categorising the knowledge gaps and geographic regions where resources are needed and discussing future recommendations to improve our understanding of anguillids. We find stark disparity between the quality and length of data available to assess population trends and conservation priorities in temperate and tropical anguillids. Of the 13 species assessed, four were listed as ‘Threatened’ (Vulnerable, Endangered or Critically Endangered; four were Near Threatened, three were Data Deficient and two were deemed Least Concern. Comparing with other diadromous species, we examine the multiple threats that impact eels during their different life-history stages, highlighting the challenges of applying the Red List Categories and Criteria to geographically-expansive, catadromous and panmictic groups of species.

    Transplantation of alginate-encapsulated islets has the potential to treat patients suffering from type I diabetes, a condition characterized by an autoimmune attack against insulin-secreting beta cells. However, there are multiple immunological challenges associated with this procedure, all of which must be adequately addressed prior to translation from trials in small animal and nonhuman primate models to human clinical trials. Principal threats to graft viability include immune-mediated destruction triggered by immunogenic alginate impurities, unfavorable polymer composition and surface characteristics, and release of membrane-permeable antigens, as well as damage associated molecular patterns (DAMPs) by the encapsulated islets themselves. The lack of standardization of significant parameters of bioencapsulation device design and manufacture (i.e., purification protocols, surface-modification grafting techniques, alginate composition modifications) between labs is yet another obstacle that must be overcome before a clinically effective and applicable protocol for encapsulating islets can be implemented. Nonetheless, substantial progress is being made, as is evident from prolonged graft survival times and improved protection from immune-mediated graft destruction reported by various research groups, but also with regard to discoveries of specific pathways involved in explaining observed outcomes. Progress in the latter is essential for a comprehensive understanding of the mechanisms responsible for the varying levels of immunogenicity of certain alginate devices. Successful translation of encapsulated islet transplantation from in vitro and animal model testing to human clinical trials hinges on application of this knowledge of the pathways and interactions which comprise immune-mediated rejection. Thus, this review not only focuses on the different factors contributing to provocation of the immune reaction by encapsulated islets, but also on the defining

  12. Facing policy challenges with inter- and transdisciplinary soil research focused on the UN Sustainable Development Goals

    Our current information society, populated by increasingly well-informed and critical stakeholders, presents a challenge to both the policy and science arenas. The introduction of the UN Sustainable Development Goals (SDGs) offers a unique and welcome opportunity to direct joint activities towards these goals. Soil science, even though it is not mentioned as such, plays an important role in realizing a number of SDGs focusing on food, water, climate, health, biodiversity, and sustainable land use. A plea is made for a systems approach to land use studies, to be initiated by soil scientists, in which these land-related SDGs are considered in an integrated manner. To connect with policy makers and stakeholders, two approaches are functional. The first of these is the policy cycle when planning and executing research, which includes signaling, design, decision making, implementation, and evaluation. Many current research projects spend little time on signaling, which may lead to disengagement of stakeholders. Also, implementation is often seen as the responsibility of others, while it is crucial to demonstrate - if successful - the relevance of soil science. The second approach is the DPSIR approach when following the policy cycle in land-related research, distinguishing external drivers, pressures, impact, and responses to land use change that affect the state of the land in the past, present, and future. Soil science cannot by itself realize SDGs, and interdisciplinary studies on ecosystem services (ESs) provide an appropriate channel to define contributions of soil science in terms of the seven soil functions. ESs, in turn, can contribute to addressing the six SDGs (2, 3, 6, 12, 13, and 15) with an environmental, land-related character. SDGs have a societal focus and future soil science research can only be successful if stakeholders are part of the research effort in transdisciplinary projects, based on the principle of time-consuming "joint learning".

    Full Text Available Background Thalassemia is considered an important public health problem worldwide, especially in developing and poor countries. Although several advanced techniques have been developed for prevention of thalassemia in the recent years, many adolescents and youths are still living with this disease. Independence from parents, decisions about high-risk behaviors, uncovering the identity, and adapting to mental and physical effects of the disease occur together in adolescents. Objectives This study was conducted to explore challenges of self-management empowerment in adolescents and youths with major thalassemia. Materials and Methods This was a descriptive-exploratory study. The study population consisted of adolescents and youths with major thalassemia who had medical records in the Bushehr Thalassemia Center, affiliated with Bushehr University of Medical Sciences. The study samples were purposively selected. Demographic information questionnaire and empowerment questionnaire were used to collect data from the semistructured interview. We analyzed qualitative data by content analysis method and quantitative data by descriptive (mean, standard deviation and analytical (Student's t-test, ANOVA and Pearson’s correlation coefficient statistical methods, using the statistical software SPSS 18. Results In qualitative part of the study, data from semistructured in-depth interviews with 15 participants were coded and summarized in five themes including: 1 awareness of personal changes; 2 need for adaptation; 3 maintaining independence and self-management; 4 uncovering the identity and role playing; and 5 sense of control and satisfaction. Results of the quantitative part showed that the overall score of participants on empowerment was 92.46 of 149 scores, which showed a moderate situation in the empowerment of these individuals. In addition, the empowerment score showed no statistically significant correlation with demographic characteristics

    The search for alternatives to the internal combustion engine for motor vehicles may be nothing new, but the present focus on environmental issues (dwindling fossil fuel reserves, growing awareness of the environmental impact of the internal combustion engine, etc.) makes it more topical than ever. It is no coincidence that most manufacturers and OEMs on the automotive market, and many research centers, are studying the use of batteries and fuel cells as a means of developing greener, sustainable transport solutions for the future. The European Union is considering ways of compelling manufacturers to market vehicles that are more fuel-efficient at a time when the members of the European Automobile Manufacturers Association, unlike their counterparts in Japan, are failing to meet the targets defined in voluntary agreements. Through their sales of hybrid vehicles, Japanese manufacturers have lent credibility to the notion of a market for electrified vehicles. In this way, market constraints (environmental impact of the internal combustion engine, the cost of fossil fuel, consumers, and national or European lawmakers) will push the automotive industry into marketing 'low-carbon' vehicles in the very short term. Manufacturers' product plans reveal that a wave of electrified products can be expected on the market in 2015. That implies a significant R and D effort between now and 2012, with demonstrator vehicles up and running by 2013-2014 at the latest. So now is a crucial time for research organisations to position themselves in preparation for this emerging market. Industry is hoping for technological progress in areas that cut across these varying degrees of hybridisation and electrification, namely the storage and management of electrical energy and power electronics. It is these areas that will be at the heart of research programs. In these highly competitive times, efforts should focus on: - Lowering costs (by a factor of 5 to 10 for fuel cells and 2 to 4 for

    There is a significant gap in empirical evidence on the menstrual hygiene management (MHM) challenges faced by adolescent girls and women in emergency contexts, and on appropriate humanitarian response approaches to meet their needs in diverse emergency contexts. To begin filling the gap in the evidence, we conducted a study in two diverse contexts (Myanmar and Lebanon), exploring the MHM barriers facing girls and women, and the various relevant sectoral responses being conducted (e.g. water, sanitation and hygiene (WASH), Protection, Health, Education and Camp Management). Two qualitative assessments were conducted: one in camps for internally displaced populations in Myanmar, and one with refugees living in informal settlements and host communities in Lebanon. Key informant interviews were conducted with emergency response staff in both sites, and focus group discussion and participatory mapping activities conducted with adolescent girls and women. Key findings included that there was insufficient access to safe and private facilities for MHM coupled with displacement induced shifts in menstrual practices by girls and women. Among staff, there was a narrow interpretation of what an MHM response includes, with a focus on supplies; significant interest in understanding what an improved MHM response would include and acknowledgement of limited existing MHM guidance across various sectors; and insufficient consultation with beneficiaries, related to discomfort asking about menstruation, and limited coordination between sectors. There is a significant need for improved guidance across all relevant sectors for improving MHM response in emergency context, along with increased evidence on effective approaches for integrating MHM into existing responses.
