Control of Future Air Traffic Systems via Complexity Bound Management

NASA Technical Reports Server (NTRS)

Alexandrov, Natalia

2013-01-01

The complexity of the present system for managing air traffic has led to "discreteness" in approaches to creating new concepts: new concepts are created as point designs, based on experience, expertise, and creativity of the proposer. Discrete point designs may be highly successful but they are difficult to substantiate in the face of equally strong substantiation of competing concepts, as well as the state of the art in concept evaluation via simulations. Hybrid concepts may present a compromise - the golden middle. Yet a hybrid of sometimes in principle incompatible concepts forms another point design that faces the challenge of substantiation and validation. We are faced with the need to re-design the air transportation system ab initio. This is a daunting task, especially considering the problem of transitioning from the present system to any fundamentally new system. However, design from scratch is also an opportunity to reconsider approaches to new concept development. In this position paper we propose an approach, Optimized Parametric Functional Design, for systematic development of concepts for management and control of airspace systems, based on optimization formulations in terms of required system functions and states. This reasoning framework, realizable in the context of ab initio system design, offers an approach to deriving substantiated airspace management and control concepts. With growing computational power, we hope that the approach will also yield a methodology for actual dynamic control of airspace

When changes happen as rapidly as they do today, the literature is often absent. Although related literature may be available to substantiate a direction to take when faced with some issue to resolve, that literature may be vague in terms of its applicability within health care. The idea of a circle of advisors was instituted to gain insight from experts who had faced similar challenges and often had extensive networks of shared experiences. The use of a sequential dialog identified specific talents to be developed in a chief nurse executive enculturation program.

2014-01-01

SUMMARY The development of complex hybrid organic-inorganic devices faces several challenges, including how they can generate energy. Cells face similar challenges regarding local energy production. Mammalian sperm solve this problem by generating ATP down the flagellar principal piece by means of glycolytic enzymes, several of which are tethered to a cytoskeletal support via germ cell-specific targeting domains. Inspired by this design, we have produced recombinant hexokinase type 1 and glucose-6-phosphate isomerase capable of oriented immobilization on a nickel-nitrilotriacetic acid modified surface. Specific activities of enzymes tethered via this strategy were substantially higher than when randomly adsorbed. Furthermore, these enzymes showed sequential activities when tethered onto the same surface. This is the first demonstration of surface-tethered pathway components showing sequential enzymatic activities, and it provides a first step toward reconstitution of glycolysis on engineered hybrid devices.

A Two-Stage Framework for 3D Face Reconstruction from RGBD Images.

PubMed

Wang, Kangkan; Wang, Xianwang; Pan, Zhigeng; Liu, Kai

2014-08-01

This paper proposes a new approach for 3D face reconstruction with RGBD images from an inexpensive commodity sensor. The challenges we face are: 1) substantial random noise and corruption are present in low-resolution depth maps; and 2) there is high degree of variability in pose and face expression. We develop a novel two-stage algorithm that effectively maps low-quality depth maps to realistic face models. Each stage is targeted toward a certain type of noise. The first stage extracts sparse errors from depth patches through the data-driven local sparse coding, while the second stage smooths noise on the boundaries between patches and reconstructs the global shape by combining local shapes using our template-based surface refinement. Our approach does not require any markers or user interaction. We perform quantitative and qualitative evaluations on both synthetic and real test sets. Experimental results show that the proposed approach is able to produce high-resolution 3D face models with high accuracy, even if inputs are of low quality, and have large variations in viewpoint and face expression.

15 years after liberation from apartheid, South Africans are facing new challenges for which the highest calibre of leadership, vision, and commitment is needed. The effect of the unprecedented HIV/AIDS epidemic has been immense. Substantial increases in mortality and morbidity are threatening to overwhelm the health system and undermine the potential of South Africa to attain the Millennium Development Goals (MDGs). However The Lancet's Series on South Africa has identified several examples of leadership and innovation that point towards a different future scenario. We discuss the type of vision, leadership, and priority actions needed to achieve such a change. We still have time to change the health trajectory of the country, and even meet the MDGs. The South African Government, installed in April, 2009, has the mandate and potential to address the public health emergencies facing the country--will they do so or will another opportunity and many more lives be lost?

The climate is changing and this poses significant threats to human health. Climate change is one of the greatest challenges facing Pacific Island countries and territories due to their unique geophysical features, and their social, economic and cultural characteristics. The Pacific region also faces challenges with widely dispersed populations, limited resources and fragmented health systems. Over the past few years, there has been a substantial increase in international aid for health activities aimed at adapting to the threats of climate change. This funding needs to be used strategically to ensure an effective approach to reducing the health risk from climate change. Respecting the principles of development effectiveness will result in more effective and sustainable adaptation, in particular, 1) processes should be owned and driven by local communities, 2) investments should be aligned with existing national priorities and policies, and 3) existing systems must not be ignored, but rather expanded upon and reinforced.

Trismus can be a challenging consequence of ballistic trauma to the face, and has rarely been described in the setting of face transplantation. Almost half of all current face transplant recipients in the world received transplantation to restore form and function after a ballistic injury. Here we report our experience and challenges with long standing trismus after face transplantation. We reviewed the medical records of our face transplant recipients whose indication was ballistic injury. We focused our review on trismus and assessed the pre-, peri- and postoperative planning, surgery and functional outcomes. Two patients received partial face transplantation, including the midface for ballistic trauma. Both patients suffered from impaired mouth opening, speech intelligibility, and oral competence. Severe scarring of the temporomandibular joint (TMJ) required intraoperative release in both patients, and additional total condylectomy on the left side 6 months posttransplant for 1 patient. Posttransplant, both patients achieved an improvement in mouth opening; however, there was persistent trismus. One year after transplantation, range of motion of the jaw had improved for both patients. Independent oral food intake was possible 1 year after surgery, although spillage of liquids and mixed consistency solids persisted. Speech intelligibility testing showed impairments in the immediate postoperative period, with improvement to over 85% for both patients at 1 year posttransplant. Ballistic trauma to the face and subsequent reconstructive measures can cause significant scarring and covert injuries to structures such as the TMJ, resulting in long standing trismus. Meticulous individual planning prior to interventions such as face transplantation must take these into account. We encourage intraoperative evaluation of these structures as well as peri- and postoperative treatment when necessary. Due to the nature of the primary injury, functional outcomes after face transplantation in these patients may differ substantially from those of other indications.

Forensic facial identification examiners are required to match the identity of faces in images that vary substantially, owing to changes in viewing conditions and in a person's appearance. These identifications affect the course and outcome of criminal investigations and convictions. Despite calls for research on sources of human error in forensic examination, existing scientific knowledge of face matching accuracy is based, almost exclusively, on people without formal training. Here, we administered three challenging face matching tests to a group of forensic examiners with many years' experience of comparing face images for law enforcement and government agencies. Examiners outperformed untrained participants and computer algorithms, thereby providing the first evidence that these examiners are experts at this task. Notably, computationally fusing responses of multiple experts produced near-perfect performance. Results also revealed qualitative differences between expert and non-expert performance. First, examiners' superiority was greatest at longer exposure durations, suggestive of more entailed comparison in forensic examiners. Second, experts were less impaired by image inversion than non-expert students, contrasting with face memory studies that show larger face inversion effects in high performers. We conclude that expertise in matching identity across unfamiliar face images is supported by processes that differ qualitatively from those supporting memory for individual faces. PMID:26336174

Changes in issues and advances in methodology have contributed to substantial progress in tree physiology research during the last several decades. Current research focuses on process interactions in complex systems and the integration of processes across multiple spatial and temporal scales. An increasingly important challenge for future research is assuring sustainability of production systems and forested ecosystems in the face of increased demands for natural resources and human disturbance of forests. Meeting this challenge requires significant shifts in research approach, including the study of limitations of productivity that may accompany achievement of system sustainability, and a focus on the biological capabilities of complex land bases altered by human activity.

2015-04-01

The reality of laboratory diagnostics as a whole, and hemostasis testing in particular, is evolving under new paradigms of efficiency. The driving forces of health care and laboratory diagnostics in the third millennium are mainly represented by macro- and microeconomics. In a world with limited resources, shattered by an unprecedented economic crisis, laboratory diagnostics is undergoing a substantial reorganization, with emergence of new models under the imperative of terms, such as bedside testing, consolidation, and networking. The paradigms under which these changes are being developed include a variety of environment, preanalytical, technological, professional, and health-care aspects. The maintenance of continued quality is indeed the major challenge to be faced in the foreseeable future. In fact, some challenges prepotently emerge during a consolidation process, which basically involve delayed testing, centrifugation, transportation, and stability of the specimens, as well as the potential mismatch of sample matrix. This article is aimed to provide an overview of the current economic scenario of laboratory diagnostics and discuss the changing face of hemostasis testing in modern laboratories, providing a synthetic overview about potential drawbacks of actualized solutions.

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.

We examined trends in doctoral education in public health and the challenges facing practice-oriented doctor of public health (DrPH) programs. We found a rapid rise in the numbers of doctoral programs and students. Most of the increase was in PhD students who in 2006 composed 73% of the total 5247 current public health doctoral students, compared with 53% in 1985. There has also been a substantial increase (40%) in students in DrPH programs since 2002. Challenges raised by the increased demand for DrPH practice-oriented education relate to admissions, curriculum, assessment processes, and faculty hiring and promotion. We describe approaches to practice-based doctoral education taken by three schools of public health. PMID:18633094

ASSESSING PARENTING IN THE CONTEXT OF REUNIFICATION OF INFANTS/TODDLERS AND THEIR FAMILIES: HOW TO FACE THE CHALLENGES?

Vischer, Anne-Fleur W K; Grietens, Hans; Knorth, Erik J; Mulder, Hans

2017-05-01

Since a substantial portion of infants and toddlers reenter care after reunification, the question of whether family reunification is feasible needs to be answered very cautiously. How parenting is assessed is of major importance in answering this question, but the quality of these assessments is often poor. With an eye to improving current practice, we conducted an integrative review, in which we analyzed the challenges related to the assessment of parenting vis-à-vis reunification and linked relevant knowledge from research with significant know-how from practice. The challenges appear to be embedded in the struggle to define (especially good enough) parenting and the complex context of child protection. As an answer to the challenges, the integrative review resulted in a framework of four key components required for sufficient parenting-assessment practice: (a) the use and development of expertise; and (b) providing families aiming for reunification with an intervention that is intensive, (c) flexible, and (d) organized as teamwork. Providing families with such an intervention gives them the opportunity to make substantial changes in their parenting and helps professionals assess the capacity of parents to grow to an acceptable level of caretaking for their child. Further implications for research and practice are discussed. © 2017 Michigan Association for Infant Mental Health.

Applied aerodynamics: Challenges and expectations

Peterson, Victor L.; Smith, Charles A.

1993-01-01

Aerospace is the leading positive contributor to this country's balance of trade, derived largely from the sale of U.S. commercial aircraft around the world. This powerfully favorable economic situation is being threatened in two ways: (1) the U.S. portion of the commercial transport market is decreasing, even though the worldwide market is projected to increase substantially; and (2) expenditures are decreasing for military aircraft, which often serve as proving grounds for advanced aircraft technology. To retain a major share of the world market for commercial aircraft and continue to provide military aircraft with unsurpassed performance, the U.S. aerospace industry faces many technological challenges. The field of applied aerodynamics is necessarily a major contributor to efforts aimed at meeting these technological challenges. A number of emerging research results that will provide new opportunities for applied aerodynamicists are discussed. Some of these have great potential for maintaining the high value of contributions from applied aerodynamics in the relatively near future. Over time, however, the value of these contributions will diminish greatly unless substantial investments continue to be made in basic and applied research efforts. The focus: to increase understanding of fluid dynamic phenomena, identify new aerodynamic concepts, and provide validated advanced technology for future aircraft.

Pediatric palliative care and pediatric medical ethics: opportunities and challenges.

PubMed

Feudtner, Chris; Nathanson, Pamela G

2014-02-01

The fields of pediatric palliative care (PPC) and pediatric medical ethics (PME) overlap substantially, owing to a variety of historical, cultural, and social factors. This entwined relationship provides opportunities for leveraging the strong communication skills of both sets of providers, as well as the potential for resource sharing and research collaboration. At the same time, the personal and professional relationships between PPC and PME present challenges, including potential conflict with colleagues, perceived or actual bias toward a palliative care perspective in resolving ethical problems, potential delay or underuse of PME services, and a potential undervaluing of the medical expertise required for PPC consultation. We recommend that these challenges be managed by: (1) clearly defining and communicating clinical roles of PPC and PME staff, (2) developing questions that may prompt PPC and PME teams to request consultation from the other service, (3) developing explicit recusal criteria for PPC providers who also provide PME consultation, (4) ensuring that PPC and PME services remain organizationally distinct, and (5) developing well-defined and broad scopes of practice. Overall, the rich relationship between PPC and PME offers substantial opportunities to better serve patients and families facing difficult decisions.

2014-12-01

An estimated 1.6 million people die from diarrheal diseases each year due to lack of access to safe water and sanitation, and persons with physical disabilities face additional barriers. In Cambodia, approximately 5% of the population is disabled, presenting substantial obstacles in accessing these basic services. The purpose of this study was twofold: first, to identify the challenges facing persons with physical disabilities in accessing safe household water and basic hygiene in rural Cambodia; and, second, to use these results to generate policy and practice recommendations for the water and sanitation hygiene sector implementing water treatment system interventions in rural settings. Fifteen field interviews were conducted with persons with physical disabilities. Thematic analysis was used to identify six main themes. The results indicated that environmental barriers to access were greater in the workplace than household settings and those persons with disabilities had greater awareness about safe drinking water compared to basic hygiene. Additionally, lack of physical strength, distance to water, and lack of financial means were noted as common access barriers. The findings support ongoing research and offer insight into the particular challenges facing persons with physical disabilities in rural areas in accessing safe drinking water and basic hygiene.

Achieving the upper limits of face identification accuracy in forensic applications can minimize errors that have profound social and personal consequences. Although forensic examiners identify faces in these applications, systematic tests of their accuracy are rare. How can we achieve the most accurate face identification: using people and/or machines working alone or in collaboration? In a comprehensive comparison of face identification by humans and computers, we found that forensic facial examiners, facial reviewers, and superrecognizers were more accurate than fingerprint examiners and students on a challenging face identification test. Individual performance on the test varied widely. On the same test, four deep convolutional neural networks (DCNNs), developed between 2015 and 2017, identified faces within the range of human accuracy. Accuracy of the algorithms increased steadily over time, with the most recent DCNN scoring above the median of the forensic facial examiners. Using crowd-sourcing methods, we fused the judgments of multiple forensic facial examiners by averaging their rating-based identity judgments. Accuracy was substantially better for fused judgments than for individuals working alone. Fusion also served to stabilize performance, boosting the scores of lower-performing individuals and decreasing variability. Single forensic facial examiners fused with the best algorithm were more accurate than the combination of two examiners. Therefore, collaboration among humans and between humans and machines offers tangible benefits to face identification accuracy in important applications. These results offer an evidence-based roadmap for achieving the most accurate face identification possible. Copyright © 2018 the Author(s). Published by PNAS.

A plurality of pre-mix tubes or passages extend axially through the hollow body with inlets at the upstream end face and outlets at the downstream end face. An exterior surface of the downstream end face is formed with three-dimensional surface features that increase a total surface area of the exterior surface as compared to a substantially flat, planar downstream end face.

Genetic specificity of face recognition.

Specific cognitive abilities in diverse domains are typically found to be highly heritable and substantially correlated with general cognitive ability (g), both phenotypically and genetically. Recent twin studies have found the ability to memorize and recognize faces to be an exception, being similarly heritable but phenotypically substantially uncorrelated both with g and with general object recognition. However, the genetic relationships between face recognition and other abilities (the extent to which they share a common genetic etiology) cannot be determined from phenotypic associations. In this, to our knowledge, first study of the genetic associations between face recognition and other domains, 2,000 18- and 19-year-old United Kingdom twins completed tests assessing their face recognition, object recognition, and general cognitive abilities. Results confirmed the substantial heritability of face recognition (61%), and multivariate genetic analyses found that most of this genetic influence is unique and not shared with other cognitive abilities.

In this, to our knowledge, first study of the genetic associations between face recognition and other domains, 2,000 18- and 19-year-old United Kingdom twins completed tests assessing their face recognition, object recognition, and general cognitive abilities. Results confirmed the substantial heritability of face recognition (61%), and multivariate genetic analyses found that most of this genetic influence is unique and not shared with other cognitive abilities.

Emergency departments throughout the USA may have some familiarity with the management of envenomation from indigenous snake species such as Crotalinae (rattlesnakes) and Micrurus (coral snakes). However, venomous species may include exotic reptiles whose bites pose substantial treatment challenges due to both a lack of experience and the difficulty in obtaining antivenoms. Two pet cobra envenomation incidents illustrate the challenges that face emergency departments, especially in urban settings, that are confronted with these exposures. It is important for emergency departments to be aware of the large underground presence of exotic venomous reptile pets and to utilise the expertise of regional poison centres that will also assist in the procurement of exotic antivenoms.

Audiovisual perceptual learning with multiple speakers.

PubMed

Mitchel, Aaron D; Gerfen, Chip; Weiss, Daniel J

2016-05-01

One challenge for speech perception is between-speaker variability in the acoustic parameters of speech. For example, the same phoneme (e.g. the vowel in "cat") may have substantially different acoustic properties when produced by two different speakers and yet the listener must be able to interpret these disparate stimuli as equivalent. Perceptual tuning, the use of contextual information to adjust phonemic representations, may be one mechanism that helps listeners overcome obstacles they face due to this variability during speech perception. Here we test whether visual contextual cues to speaker identity may facilitate the formation and maintenance of distributional representations for individual speakers, allowing listeners to adjust phoneme boundaries in a speaker-specific manner. We familiarized participants to an audiovisual continuum between /aba/ and /ada/. During familiarization, the "b-face" mouthed /aba/ when an ambiguous token was played, while the "D-face" mouthed /ada/. At test, the same ambiguous token was more likely to be identified as /aba/ when paired with a stilled image of the "b-face" than with an image of the "D-face." This was not the case in the control condition when the two faces were paired equally with the ambiguous token. Together, these results suggest that listeners may form speaker-specific phonemic representations using facial identity cues.

Commercial influence and global nongovernmental public action in health and pharmaceutical policies.

PubMed

Koivusalo, Meri; Mackintosh, Maureen

2011-01-01

Nongovernmental public action has been effective in influencing global agenda-setting in health and pharmaceutical policies, yet its record in influencing solutions to the problems identified has been notably more limited. While trade policies have been particularly resistant to change, more substantial changes are observable in global health policies and global health governance. However, some of the directions of change may not be conducive to the democratic accountability of global health governance, to the wise use of public resources, to health systems development, or to longer-term access to health care within developing countries. The authors argue that observed changes in global health policies can be understood as accommodating to corporate concerns and priorities. Furthermore, the changing global context and the commercialization of global public action itself pose sharp challenges to the exercise of influence by global nongovernmental public actors. Nongovernmental organizations not only face a major challenge in terms of the imbalance in power and resources between themselves and corporate interest groups when seeking to influence policymaking; they also face the problem of corporate influence on public action itself.

Recreational drugs. Societal and professional issues.

PubMed

Solari-Twadell, P A

1991-06-01

Recreational drug use presents a challenge to society and, in particular, the profession of nursing. Recreational drug use must be appreciated for the implications it presents for the episodes of abuse and development of chronic health problems. The effects and recreational use of volatile substances, cannabis, opioids, barbiturates, benzodiazepines, amphetamines, cocaine, psychedelics, and designer drugs as well as alcohol, caffeine, and nicotine must be acknowledged and understood if options for change are to be considered. The resultant cost of recreational drug use as well as health care implications, public safety, and prevention are significant issues society is faced with today. These issues will continue to be significant unless the current posture toward recreational drug use and abuse is addressed. The profession of nursing continues to be faced with the problems associated with recreational drug use not only through caring for clients, but immediately by the effects of recreational drug use on individual professional nurses. To respond effectively, nursing education and nursing research must be challenged to create an emphasis on this focus. Only through this type of multifocal approach will long-term substantial change be affected for the betterment of future generations.

Decision Making Under Uncertainty and Complexity: A Model-Based Scenario Approach to Supporting Integrated Water Resources Management

NASA Astrophysics Data System (ADS)

Liu, Y.; Gupta, H.; Wagener, T.; Stewart, S.; Mahmoud, M.; Hartmann, H.; Springer, E.

2007-12-01

Some of the most challenging issues facing contemporary water resources management are those typified by complex coupled human-environmental systems with poorly characterized uncertainties. In other words, major decisions regarding water resources have to be made in the face of substantial uncertainty and complexity. It has been suggested that integrated models can be used to coherently assemble information from a broad set of domains, and can therefore serve as an effective means for tackling the complexity of environmental systems. Further, well-conceived scenarios can effectively inform decision making, particularly when high complexity and poorly characterized uncertainties make the problem intractable via traditional uncertainty analysis methods. This presentation discusses the integrated modeling framework adopted by SAHRA, an NSF Science & Technology Center, to investigate stakeholder-driven water sustainability issues within the semi-arid southwestern US. The multi-disciplinary, multi-resolution modeling framework incorporates a formal scenario approach to analyze the impacts of plausible (albeit uncertain) alternative futures to support adaptive management of water resources systems. Some of the major challenges involved in, and lessons learned from, this effort will be discussed.

Clostridium difficile Infection.

Clostridium difficile infection is a major health care challenge in terms of patient and economic consequences. For the patient, it is a morbid and sometimes a life-threatening iatrogenic complication of antibiotic treatment. In the United States, the provider's institution may face financial penalties, because the Centers for Disease Control and Prevention views this as an iatrogenic health care-associated complication that may not be reimbursable by the Centers for Medicare and Medicaid Services; this has resulted in substantial incentives for new approaches to prevention and treatment.

The world’s crop productivity is stagnating whereas population growth, rising affluence, and mandates for biofuels put increasing demands on agriculture. Meanwhile, demand for increasing cropland competes with equally crucial global sustainability and environmental protection needs. Addressing this looming agricultural crisis will be one of our greatest scientific challenges in the coming decades, and success will require substantial improvements at many levels. We assert that increasing the efficiency and productivity of photosynthesis in crop plants will be essential if this grand challenge is to be met. Here, we explore an array of prospective redesigns of plant systems at various scales, all aimed at increasing crop yields through improved photosynthetic efficiency and performance. Prospects range from straightforward alterations, already supported by preliminary evidence of feasibility, to substantial redesigns that are currently only conceptual, but that may be enabled by new developments in synthetic biology. Although some proposed redesigns are certain to face obstacles that will require alternate routes, the efforts should lead to new discoveries and technical advances with important impacts on the global problem of crop productivity and bioenergy production.

The health and health system of South Africa: historical roots of current public health challenges.

PubMed

Coovadia, Hoosen; Jewkes, Rachel; Barron, Peter; Sanders, David; McIntyre, Diane

2009-09-05

The roots of a dysfunctional health system and the collision of the epidemics of communicable and non-communicable diseases in South Africa can be found in policies from periods of the country's history, from colonial subjugation, apartheid dispossession, to the post-apartheid period. Racial and gender discrimination, the migrant labour system, the destruction of family life, vast income inequalities, and extreme violence have all formed part of South Africa's troubled past, and all have inexorably affected health and health services. In 1994, when apartheid ended, the health system faced massive challenges, many of which still persist. Macroeconomic policies, fostering growth rather than redistribution, contributed to the persistence of economic disparities between races despite a large expansion in social grants. The public health system has been transformed into an integrated, comprehensive national service, but failures in leadership and stewardship and weak management have led to inadequate implementation of what are often good policies. Pivotal facets of primary health care are not in place and there is a substantial human resources crisis facing the health sector. The HIV epidemic has contributed to and accelerated these challenges. All of these factors need to be addressed by the new government if health is to be improved and the Millennium Development Goals achieved in South Africa.

NASA flight controllers - Meeting cultural and leadership challenges on the critical path to mission success

Clement, James L., Jr.; Ritsher, Jennifer Boyd

2006-01-01

As part of its preparation for missions to the Moon and Mars, NASA has identified high priority critical path roadmap (CPR) questions, two of which focus on the performance of mission control personnel. NASA flight controllers have always worked in an incredibly demanding setting, but the International Space Station poses even more challenges than prior missions. We surveyed 14 senior ISS flight controllers and a contrasting sample of 12 more junior controllers about the management and cultural challenges they face and the most effective strategies for addressing them. There was substantial consensus among participants on some issues, such as the importance of building a personal relationship with Russian colleagues. Responses from junior and senior controllers differed in some areas, such as training. We frame the results in terms of two CPR questions. We aim to use our results to improve flight controller training.

Pigeons trade efficiency for stability in response to level of challenge during confined flight.

PubMed

Williams, C David; Biewener, Andrew A

Individuals traversing challenging obstacles are faced with a decision: they can adopt traversal strategies that minimally disrupt their normal locomotion patterns or they can adopt strategies that substantially alter their gait, conferring new advantages and disadvantages. We flew pigeons (Columba livia) through an array of vertical obstacles in a flight arena, presenting them with this choice. The pigeons selected either a strategy involving only a slight pause in the normal wing beat cycle, or a wings-folded posture granting reduced efficiency but greater stability should a misjudgment lead to collision. The more stable but less efficient flight strategy was not used to traverse easy obstacles with wide gaps for passage but came to dominate the postures used as obstacle challenge increased with narrower gaps and there was a greater chance of a collision. These results indicate that birds weigh potential obstacle negotiation strategies and estimate task difficulty during locomotor pattern selection.

Developing a comprehensive curriculum for public health advocacy.

Hines, Ayelet; Jernigan, David H

2012-11-01

There is a substantial gap in public health school curricula regarding advocacy. Development of such a curriculum faces three challenges: faculty lack advocacy skills and experience; the public health literature on effective advocacy is limited; and yet a successful curriculum must be scalable to meet the needs of approximately 9,000 public health students graduating each year. To meet these challenges, we propose a 100-hour interactive online curriculum in five sections: campaigning and organizing, policy making and lobbying, campaign communications, new media, and fund-raising. We outline the content for individual modules in each of these sections, describe how the curriculum would build on existing interactive learning and social media technologies, and provide readers the opportunity to "test-drive" excerpts of a module on "grasstops" organizing. Developing advocacy skills and expertise is critical to meeting the challenges of public health today, and we provide a blueprint for how such training might be brought to scale in the field.

Effects of disputes and easement violations on the cost-effectiveness of land conservation

Arcese, Peter

2015-01-01

Conservation initiatives to protect and restore valued species communities in human-dominated landscapes face challenges linked to their potential costs. Conservation easements on private land may represent a cost-effective alternative to land purchase, but long-term costs to monitor and enforce easements, or defend legal challenges, remain uncertain. We explored the cost-effectiveness of conservation easements, defined here as the fraction of the high-biodiversity landscape potentially protected via investment in easements versus land purchase. We show that easement violation and dispute rates substantially affect the estimated long-term cost-effectiveness of an easement versus land purchase strategy. Our results suggest that conservation easements can outperform land purchase as a strategy to protect biodiversity as long as the rate of disputes and legal challenges is low, pointing to a critical need for monitoring data to reduce costs and maximize the value of conservation investments.

What are the most important challenges facing solid Earth science today and over the next two decades? And what is the best approach for NASA, in partnership with other agencies, to address those challenges? A new report, Living on a Restless Planet, provides a blueprint for answering these questions. The top priority for a new spacecraft mission in the area of solid Earth science over the next 5 years, according to this report, is a satellite dedicated to Interferometric Synthetic Aperture Radar (InSAR). At the request of NASA, the Solid Earth Science Working Group (SESWG) developed a strategy for the highest priority objectives in solid Earth science for the space agency over the next 25 years. The strategy addresses six challenges that are of fundamental scientific importance, have strong implications for society, and are amenable to substantial progress through a concerted series of scientific observations from space.

Nanomedicine for safe healing of bone trauma: Opportunities and challenges

PubMed Central

Behzadi, Shahed; Luther, Gaurav A.; Harris, Mitchel B.; Farokhzad, Omid C.; Mahmoudi, Morteza

2017-01-01

Historically, high-energy extremity injuries resulting in significant soft-tissue trauma and bone loss were often deemed unsalvageable and treated with primary amputation. With improved soft-tissue coverage and nerve repair techniques, these injuries now present new challenges in limb-salvage surgery. High-energy extremity trauma is pre-disposed to delayed or unpredictable bony healing and high rates of infection, depending on the integrity of the soft-tissue envelope. Furthermore, orthopedic trauma surgeons are often faced with the challenge of stabilizing and repairing large bony defects while promoting an optimal environment to prevent infection and aid bony healing. During the last decade, nanomedicine has demonstrated substantial potential in addressing the two major issues intrinsic to orthopedic traumas (i.e., high infection risk and low bony reconstruction) through combatting bacterial infection and accelerating/increasing the effectiveness of the bone-healing process. This review presents an overview and discusses recent challenges and opportunities to address major orthopedic trauma through nanomedical approaches. PMID:28918266

Risk analysis for U.S. offshore wind farms: the need for an integrated approach.

PubMed

Staid, Andrea; Guikema, Seth D

2015-04-01

Wind power is becoming an increasingly important part of the global energy portfolio, and there is growing interest in developing offshore wind farms in the United States to better utilize this resource. Wind farms have certain environmental benefits, notably near-zero emissions of greenhouse gases, particulates, and other contaminants of concern. However, there are significant challenges ahead in achieving large-scale integration of wind power in the United States, particularly offshore wind. Environmental impacts from wind farms are a concern, and these are subject to a number of on-going studies focused on risks to the environment. However, once a wind farm is built, the farm itself will face a number of risks from a variety of hazards, and managing these risks is critical to the ultimate achievement of long-term reductions in pollutant emissions from clean energy sources such as wind. No integrated framework currently exists for assessing risks to offshore wind farms in the United States, which poses a challenge for wind farm risk management. In this "Perspective", we provide an overview of the risks faced by an offshore wind farm, argue that an integrated framework is needed, and give a preliminary starting point for such a framework to illustrate what it might look like. This is not a final framework; substantial work remains. Our intention here is to highlight the research need in this area in the hope of spurring additional research about the risks to wind farms to complement the substantial amount of on-going research on the risks from wind farms. © 2015 Society for Risk Analysis.

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. ISS flight controllers have had to find ways to maintain effective team performance in this challenging new context. The goal of this study was to systematically identify and evaluate the major leadership and cultural challenges faces by ISS flight controllers, and to highlight the approaches that they have found most effective to surmount these challenges. We conducted a qualitative survey using a semi-structured interview. Subjects included 14 senior NASA flight controllers who were chosen on the basis of having had substantial experience working with international partners. Data were content analyzed using an iterative process with multiple coders and consensus meetings to resolve discrepancies. To further explore the meaning of the interview findings, we also conducted some new analyses of data from a previous questionnaire study of Russian and American ISS mission control personnel. The interview data showed that respondents had substantial consensus on several leadership and cultural challenges and on key strategies for dealing with them, and they offered a wide range of specific tactics for implementing these strategies. Surprisingly few respondents offered strategies for addressing the challenge of working with team members whose native language is not American English. The questionnaire data showed that Americans think it is more important than Russians that mission control personnel speak the same dialect of one shared common language. Although specific to the ISS program, our results are consistent with recent management, cultural, and aerospace research. We aim to use our results to improve training for current and future ISS flight controllers.

Cadaveric face transplant models are routinely used for technical allograft design, perfusion assessment, and transplant simulation but are associated with substantial limitations. The purpose of this study was to describe the experience of implementing a translational donor research facial procurement and solid organ allograft recovery model. Institutional review board approval was obtained, and a 49-year-old, brain-dead donor was identified for facial vascularized composite allograft research procurement. The family generously consented to donation of solid organs and the total face, eyelids, ears, scalp, and skeletal subunit allograft. The successful sequence of computed tomographic scanning, fabrication and postprocessing of patient-specific cutting guides, tracheostomy placement, preoperative fluorescent angiography, silicone mask facial impression, donor facial allograft recovery, postprocurement fluorescent angiography, and successful recovery of kidneys and liver occurred without any donor instability. Preservation of the bilateral external carotid arteries, facial arteries, occipital arteries, and bilateral thyrolinguofacial and internal jugular veins provided reliable and robust perfusion to the entirety of the allograft. Total time of facial procurement was 10 hours 57 minutes. Essential to clinical face transplant outcomes is the preparedness of the institution, multidisciplinary face transplant team, organ procurement organization, and solid organ transplant colleagues. A translational facial research procurement and solid organ recovery model serves as an educational experience to modify processes and address procedural, anatomical, and logistical concerns for institutions developing a clinical face transplantation program. This methodical approach best simulates the stressors and challenges that can be expected during clinical face transplantation. Therapeutic, V.

ASF: Facing the Challenges for 15 Years and Counting

NASA Astrophysics Data System (ADS)

La Belle-Hamer, N.; Nicoll, J.; Atwood, D.; Arko, S.

2006-12-01

The Alaska Satellite Facility (ASF) of the Geophysical Institute, University of Alaska Fairbanks, has just celebrated its 15th year of experience in satellite remote sensing. ASF is involved in a wide range of activities - - from downlinking satellite data to developing data analysis tools, value-added products, and training for Synthetic Aperture Radar (SAR) users. Satellite remote sensing data are acquired, processed, analyzed, and archived by ASF from several satellites; ASF has built expertise in handling and manipulating the data, SAR in particular. SAR is the only satellite imagery in the world today that can be acquired at any time of the day or night and during adverse weather conditions. It can be used to develop value-added products to aid in global climate change research. Examples include the SAR-derived coastal winds in the Gulf of Alaska and Bering Sea; monitoring of the major ice shelves in the Arctic and Antarctic; and examining the impact on sea level from the Greenland ice sheets and glaciers. The challenges facing the use of remote-sensing data in climate change research can be divided into three major categories: economical, political, and technical. The expense of designing, building, and launching a satellite is substantial. The costs of the ground segment including data management can be substantial and should not be neglected. The US agency funding climate often has the research community pushing for new missions against declining federal budgets in direct competition with ongoing missions. On the political front, data policy, data ownership, and cost recovery are issues often perceived as insurmountable by the user community. The technical issues, while challenging, are often the easiest to solve. The Japan Aerospace Exploration Agency, with the successful launch of the Advanced Land Observing System (ALOS), has embarked on a new way of handling the ground segment with the introduction of international data nodes. ASF will serve with NOAA as the Americas ALOS Data Node. With the success of the ALOS data node structure, it may well be that international cooperation will become the standard method for overcoming the challenges of global climate change research.

Isavuconazole treatment for rare fungal diseases and for invasive aspergillosis in patients with renal impairment: Challenges and lessons of the VITAL trial.

Invasive fungal disease (IFD) confers a substantial risk for morbidity and mortality to immunocompromised patients. Invasive aspergillosis (IA) is the most common IFD caused by moulds but the prevalence of other rare mould diseases, such as mucormycosis, hyalohyphomycosis and phaeohyphomycosis, may be increasing. Treatments are available for IA, but evidence to support efficacy and safety of antifungal agents for rare IFDs, or for IFDs in special patient populations, is limited or lacking. The VITAL trial was conducted to assess the efficacy and safety of isavuconazole for the treatment of patients with IA and renal impairment, or with IFDs caused by rare moulds, yeasts or dimorphic fungi. These patients stand to benefit most from a new treatment option but are unlikely to be included in a randomised, controlled trial. In this article, we review the challenges faced in the design and conduct of the VITAL trial. We also review the findings of VITAL, which included evidence of the efficacy and safety of isavuconazole. Finally, we consider the importance of trials such as VITAL to inform therapeutic decision making for clinicians faced with the challenge of treating patients with rare IFDs and as one paradigm of how to determine efficacy and safety of new drugs for rare and resistant infections without a suitable comparator. © 2018 The Authors.

While substantial advances have occurred over the last few decades in both weather and seasonal prediction, progress in improving predictions on subseasonal time scales (approximately 2 weeks to 2 months) has been slow. In this talk I will highlight some of the recent progress that has been made to improve forecasts on subseasonal time scales and outline the challenges that we face both from an observational and modeling perspective. The talk will be based primarily on the results and conclusions of a recent NASA-sponsored workshop that focused on the subseasonal prediction problem. One of the key conclusions of that workshop was that there is compelling evidence for predictability at forecast lead times substantially longer than two weeks, and that much of that predictability is currently untapped. Tropical diabatic heating and soil wetness were singled out as particularly important processes affecting predictability on these time scales. Predictability was also linked to various low-frequency atmospheric phenomena such as the annular modes in high latitudes (including their connections to the stratosphere), the Pacific/North American pattern, and the Madden-Julian Oscillation. I will end the talk by summarizing the recommendations and plans that have been put forward for accelerating progress on the subseasonal prediction problem.

The benefits of effective communication in an oncology setting are multifold and include the overall well-being of patients and health professionals, adherence to treatment regimens, psychological functioning, and improvements in quality of life. Nevertheless, there are substantial barriers and communication challenges reported by oncology nurses. This study was conducted to present a summary of communication challenges faced by oncology nurses. From November 2012 to March 2014, 121 inpatient nurses working in the oncology setting participated in an online pre-training qualitative survey that asked nurses to describe common communication challenges in communicating empathy and discussing death, dying, and end-of-life (EOL) goals of care. The results revealed six themes that describe the challenges in communicating empathically: dialectic tensions, burden of carrying bad news, lack of skills for providing empathy, perceived institutional barriers, challenging situations, and perceived dissimilarities between the nurse and the patient. The results for challenges in discussing death, dying and EOL goals of care revealed five themes: dialectic tensions, discussing specific topics related to EOL, lack of skills for providing empathy, patient/family characteristics, and perceived institutional barriers. This study emphasizes the need for institutions to provide communication skills training to their oncology nurses for navigating through challenging patient interactions. PMID:26278636

Hydration and thermal strain during tennis in the heat.

PubMed

Bergeron, Michael F

2014-04-01

Competitive tennis in the heat can prompt substantial sweat losses and extensive consequent body water and electrolyte deficits, as well as a level of thermal strain that considerably challenges a player's physiology, perception of effort, and on-court well-being and performance. Adequate hydration and optimal performance can be notably difficult to maintain when multiple same-day matches are played on successive days in hot weather. Despite the recognised effects of the heat, much more research needs to be carried out to better appreciate the broader scope and full extent of the physiological demands and hydration and thermal strain challenges facing junior and adult players in various environments, venues and competition scenarios. However, certain recommendations of best practices should be emphasised to minimise exertional heat illness risk and improve player safety, well-being and on-court performance.

Data Publishing - View from the Front

As data publishing journals - Earth System Science Data (ESSD, Copernicus, since 2009), Geophysical Data Journal (GDJ, Wiley, recent) and Scientific Data (SD, Nature Publishing Group, anticipated from May 2014) - expose data sets, implement data description and data review practices, and develop partnerships with data centres and data providers, we anticipate substantial benefits for the broad earth system and environmental research communities but also substantial challenges for all parties. A primary advantage emerges from open access to convergent data: subsurface hydrographic data near Antarctica, for example, now available for combination and comparison with nearby atmospheric data (both documented in ESSD), basin-scale precipitation data (accessed through GDJ) for comparison and interpolation with long-term global precipitation records (accessed from ESSD), or, imagining not too far into the future, stomach content and abundance data for European fish (from ESSD) linked to genetic or nutritional data (from SD). In addition to increased opportunity for discovery and collaboration, we also notice parallel developments of new tools for (published) data visualization and display and increasing acceptance of data publication as a useful and anticipated dissemination step included in project- and institution-based data management plans. All parties - providers, publishers and users - will benefit as various indexing services (SCI, SCOPUS, DCI etc.) acknowledge the creative, intellectual and meritorious efforts of data preparation and data provision. The challenges facing data publication, in most cases very familiar to the data community but made more acute by the advances in data publishing, include diverging metadata standards (among biomedical, green ocean modeling and meteorological communities, for example), adhering to standards and practices for permanent identification while also accommodating 'living' data, and maintaining prompt but rigorous review and evaluation processes in the face of unfamiliarity and overwhelming workloads.

Identifying and Coordinating Care for Complex Patients

Rudin, Robert S.; Gidengil, Courtney A.; Predmore, Zachary; Schneider, Eric C.; Sorace, James; Hornstein, Rachel

2017-01-01

Abstract In the United States, a relatively small proportion of complex patients---defined as having multiple comorbidities, high risk for poor outcomes, and high cost---incur most of the nation's health care costs. Improved care coordination and management of complex patients could reduce costs while increasing quality of care. However, care coordination efforts face multiple challenges, such as segmenting populations of complex patients to better match their needs with the design of specific interventions, understanding how to reduce spending, and integrating care coordination programs into providers' care delivery processes. Innovative uses of analytics and health information technology (HIT) may address these challenges. Rudin and colleagues at RAND completed a literature review and held discussions with subject matter experts, reaching the conclusion that analytics and HIT are being used in innovative ways to coordinate care for complex patients but that the capabilities are limited, evidence of their effectiveness is lacking, and challenges are substantial, and important foundational work is still needed.

Ryan, C; Bergin, M; Wells, J S

2017-07-01

As the global nursing workforce ages, developing a comprehensive understanding of the experiences, needs and values specific to older nurses is increasingly significant. This paper reviews the evidence with regard to the specific challenges encountered by older nurses in the workplace. A scoping review of the published literature was conducted using the electronic databases Medline, CINAHL, PsycINFO, Science Direct and Google Scholar. A total of 20 papers were included in this review, most of which were qualitative (n=14). Three quantitative studies were identified (including one study which combined a physical exam with survey methods) as well as three mixed method studies. The challenges faced by older nurses in their practice are synthesised across three primary domains: Nursing and the ageing body; Recognition and support of the older nurse and Demands associated with middle-age. As older nurses form a substantial proportion of the healthcare workforce in many countries, the development and implementation of strategies to address these challenges is of utmost importance.

Different underlying mechanisms for face emotion and gender processing during feature-selective attention: Evidence from event-related potential studies.

PubMed

Wang, Hailing; Ip, Chengteng; Fu, Shimin; Sun, Pei

2017-05-01

Face recognition theories suggest that our brains process invariant (e.g., gender) and changeable (e.g., emotion) facial dimensions separately. To investigate whether these two dimensions are processed in different time courses, we analyzed the selection negativity (SN, an event-related potential component reflecting attentional modulation) elicited by face gender and emotion during a feature selective attention task. Participants were instructed to attend to a combination of face emotion and gender attributes in Experiment 1 (bi-dimensional task) and to either face emotion or gender in Experiment 2 (uni-dimensional task). The results revealed that face emotion did not elicit a substantial SN, whereas face gender consistently generated a substantial SN in both experiments. These results suggest that face gender is more sensitive to feature-selective attention and that face emotion is encoded relatively automatically on SN, implying the existence of different underlying processing mechanisms for invariant and changeable facial dimensions.

Writing scientific articles is a daunting task for novice researchers. In this qualitative study carried out in 2007, the authors evaluated the experiences of a group of novice researchers engaged in the writing process, to elucidate the main difficulties and sources of encouragement they encountered. Sixteen novice researchers were interviewed. Most were women (10), and most were enrolled in programs of medicine (9), followed by nursing (4) and physical therapy (3). These were drawn via convenience sampling from a randomized control trial in which 48 of them were equally assigned to either an online or a face-to-face course of instruction. On completion, interviews were conducted in focus groups of four students each. The interviews were transcribed and read independently by two of the authors, who then encoded the material based on the principles of grounded theory. Initial categories were converted to major emerging themes, which were validated when participants were asked to review the findings. Triangulation of results was carried out by discussing the emerging themes in an online forum with five specialists in college writing education. Classifying the diverse responses of participants led to the emergence of four major themes: cognitive burden, group support and mentoring, difficulty in distinguishing between content and structure, and backward design of manuscripts. The themes produced by this study provide some insight into the challenges faced by novice researchers in their early attempts at scientific writing. Remedies that address these challenges are needed to substantially improve scientific writing instruction.

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.

Administering critical resources has never been more difficult that it is today. In a changing world of software innovation where major changes occur on a daily basis, it is crucial for the webmasters and server administrators to shield their data against an unknown arsenal of attacks in the hands of their attackers. Up until now this kind of defense was a privilege of the few, out-budgeted and low cost solutions let the defender vulnerable to the uprising of innovating attacking methods. Luckily, the digital revolution of the past decade left its mark, changing the way we face security forever: open source infrastructure today covers all the prerequisites for a secure web environment in a way we could never imagine fifteen years ago. Online security of large corporations, military and government bodies is more and more handled by open source application thus driving the technological trend of the 21st century in adopting open solutions to E-Commerce and privacy issues. This paper describes substantial security precautions in facing privacy and authentication issues in a totally open source web environment. Our goal is to state and face the most known problems in data handling and consequently propose the most appealing techniques to face these challenges through an open solution.

Individuals who are Deaf face challenges both similar and unique from those faced by hearing individuals when a family member is dying. This study was guided by the question “What are the challenges faced by a Deaf family member when a loved one is dying?” Methods - This qualitative study is guided by critical theory and an interpretive perspective. Robert, a college-educated older adult who has been Deaf from birth was interviewed in American Sign Language using a death history format. Results – There are challenges for Deaf family members that affect communication with both the dying person and health care professionals. Patient-family communication issues included physical challenges and financial challenges. Lack of cultural competence concerning the Deaf community created challenges communicating with professionals. Decision-making was also a challenge. Conclusions These findings provide a framework for future research concerning the needs of Deaf individuals facing the end of life and provide guidance for clinicians. PMID:19910395

One of the new challenges facing humanity is to reach increasingly further distant space targets. It is therefore of upmost importance to understand the behavior of microorganisms that will unavoidably reach the space environment together with the human body and equipment. Indeed, microorganisms could activate their stress defense mechanisms, modifying properties related to human pathogenesis. The host-microbe interactions, in fact, could be substantially affected under spaceflight conditions and the study of microorganisms' growth and activity is necessary for predicting these behaviors and assessing precautionary measures during spaceflight. This review gives an overview of the effects of microgravity and space radiation on microorganisms both in real and simulated conditions.

The regional processing centre at Sunnybrook Health Sciences Centre recently faced the substantial challenge of increasing cleaning capacity to meet the current workload and anticipated future demand without increasing its operating budget. The solution, upgrading its cleaning and decontamination system to a highly automated system, met both objectives. An analysis of the impact of the change found that the new system provided additional benefits, including improved productivity and cleaning quality; decreased costs; reduced water, electricity and chemical use; improved worker safety and morale; and decreased overtime. Investing in innovative technology improved key departmental outcomes while meeting institutional environmental and cost savings objectives.

Data from many high- and low- or middle-income countries have linked exposures during key developmental periods (in particular pregnancy and infancy) to later health and disease. Africa faces substantial challenges with persisting infectious disease and now burgeoning non-communicable disease.This paper opens the debate to the value of strengthening the developmental origins of health and disease (DOHaD) research focus in Africa to tackle critical public health challenges across the life-course. We argue that the application of DOHaD science in Africa to advance life-course prevention programmes can aid the achievement of the Sustainable Development Goals, and assist in improving health across generations. To increase DOHaD research and its application in Africa, we need to mobilise multisectoral partners, utilise existing data and expertise on the continent, and foster a new generation of young African scientists engrossed in DOHaD.

Categorical funding mechanisms traditionally used to fund public health programs are a challenge to providers serving individuals with complex needs that often span multiple service areas. Integration--a formalized, collaborative process among service systems--responds to the challenge by decreasing fragmentation of care and improving coordination. In 2000, the Massachusetts Department of Public Health (MDPH) received a one-year planning grant from the federal Substance Abuse and Mental Health Services Administration (SAMHSA) to evaluate opportunities for integrating HIV/AIDS programs and substance abuse treatment programs. The project was later expanded to include viral hepatitis programming. Outcomes include the development of a strategic plan, joint procurement initiatives, and an ongoing commitment to sustain inter-bureau integration efforts, even in the face of substantial budget reductions. Integrated approaches can promote greater efficiency, improving communication and coordination among clients, providers, and government funding agencies.

In 1856, an appeal went out to nurses in both England and Ireland, and especially to religious nurses, to care for the troops fighting in the Crimean War. The Sisters of Mercy, founded in 1831 by Venerable Catherine McAuley, answered that call. This article describes the enormous challenges the Sisters faced in that mission, which was a test of their nursing skills, flexibility, organizational ability, and their spirit of mercy. The challenges they faced professionally and as religious Sisters, the manner in which they faced those challenges, and their spiritual lives as religious women shaped their ability to give comprehensive care. Some applications are made to the challenges which religious communities and organizations working in health care face in our country at this time. Summary: This article describes the challenges faced by a group of Sisters of Mercy from England and Ireland who volunteered to serve as nurses in the Crimean War from 1856 to 1858. Applications are made to challenges which are faced by religious communities and organizations in the current secular healthcare environment. PMID:28392597

So many, yet few: Human resources for health in India.

PubMed

Rao, Krishna D; Bhatnagar, Aarushi; Berman, Peter

2012-08-13

In many developing countries, such as India, information on human resources in the health sector is incomplete and unreliable. This prevents effective workforce planning and management. This paper aims to address this deficit by producing a more complete picture of India's health workforce. Both the Census of India and nationally representative household surveys collect data on self-reported occupations. A representative sample drawn from the 2001 census was used to estimate key workforce indicators. Nationally representative household survey data and official estimates were used to compare and supplement census results. India faces a substantial overall deficit of health workers; the density of doctors, nurses and midwifes is a quarter of the 2.3/1000 population World Health Organization benchmark. Importantly, a substantial portion of the doctors (37%), particularly in rural areas (63%) appears to be unqualified. The workforce is composed of at least as many doctors as nurses making for an inefficient skill-mix. Women comprise only one-third of the workforce. Most workers are located in urban areas and in the private sector. States with poorer health and service use outcomes have a lower health worker density. Among the important human resources challenges that India faces is increasing the presence of qualified health workers in underserved areas and a more efficient skill mix. An important first step is to ensure the availability of reliable and comprehensive workforce information through live workforce registers.

Robust representations of individual faces in chimpanzees (Pan troglodytes) but not monkeys (Macaca mulatta).

PubMed

Taubert, Jessica; Weldon, Kimberly B; Parr, Lisa A

2017-03-01

Being able to recognize the faces of our friends and family members no matter where we see them represents a substantial challenge for the visual system because the retinal image of a face can be degraded by both changes in the person (age, expression, pose, hairstyle, etc.) and changes in the viewing conditions (direction and degree of illumination). Yet most of us are able to recognize familiar people effortlessly. A popular theory for how face recognition is achieved has argued that the brain stabilizes facial appearance by building average representations that enhance diagnostic features that reliably vary between people while diluting features that vary between instances of the same person. This explains why people find it easier to recognize average images of people, created by averaging multiple images of the same person together, than single instances (i.e. photographs). Although this theory is gathering momentum in the psychological and computer sciences, there is no evidence of whether this mechanism represents a unique specialization for individual recognition in humans. Here we tested two species, chimpanzees (Pan troglodytes) and rhesus monkeys (Macaca mulatta), to determine whether average images of different familiar individuals were easier to discriminate than photographs of familiar individuals. Using a two-alternative forced-choice, match-to-sample procedure, we report a behaviour response profile that suggests chimpanzees encode the faces of conspecifics differently than rhesus monkeys and in a manner similar to humans.

Employment among older workers and inequality of gender and education: evidence from a Taiwanese national survey.

2010-01-01

The aim of this research was twofold: to examine the prevalence of employment and under-employment among Taiwanese older workers (aged 50 and above), and to explore personal correlates of their employment status, in particular gender and education. Using a national representative sample, we found that: 1) a rather substantial percentage of people continued to work well into their older years; 2) the underemployment rates were substantial in the older age, and less-educated workers and women were more at risk; and 3) multivariate analysis confirmed that age, gender, personal health, spousal health, and family income were significant predictors of continued employment after age 50. Gender and education were also significantly related to the risk of under-employment. Our results highlight the importance and urgency of more concerted research to inform public labor policies, especially in an aging developing society where older workers are faced with a double challenge of economic and societal restructuring.

5 billion people around the world do not have access to safe, affordable, timely surgical care. This series of qualitative interviews was launched by The Lancet Commission on Global Surgery (LCoGS) with the aim of understanding the contextual challenges-the specific circumstances-faced by surgical care providers in low-resource settings who care for impoverished patients, and how those providers overcome these challenges. From January 2014 to February 2015, 20 LCoGS collaborators conducted semistructured interviews with 148 surgical providers in low-resource settings in 21 countries. Stratified purposive sampling was used to include both rural and urban providers, and reputational case selection identified individuals. Interviewers were trained with an implementation manual. Following immersion into de-identified texts from completed interviews, topical coding and further analysis of coded texts was completed by an independent analyst with periodic validation from a second analyst. Providers described substantial financial, geographic and cultural barriers to patient access. Rural surgical teams reported a lack of a trained workforce and insufficient infrastructure, equipment, supplies and banked blood. Urban providers face overcrowding, exacerbated by minimal clinical and administrative support, and limited interhospital care coordination. Many providers across contexts identified national health policies that do not reflect the realities of resource-poor settings. Some findings were region-specific, such as weak patient-provider relationships and unreliable supply chains. In all settings, surgical teams have created workarounds to deliver care despite the challenges. While some differences exist between countries, the barriers to safe surgery and anaesthesia are overall consistent and resource-dependent. Efforts to advance and expand global surgery must address these commonalities, while local policymakers can tailor responses to key contextual differences.

The Challenges of Afghanistan and Iraq Veterans' Transition from Military to Civilian Life and Approaches to Reconnection.

Afghanistan and Iraq veterans experienced traumas during deployment, and disrupted connections with friends and family. In this context, it is critical to understand the nature of veterans' transition to civilian life, the challenges navigated, and approaches to reconnection. We investigated these issues in a qualitative study, framed by homecoming theory, that comprised in-depth interviews with 24 veterans. Using an inductive thematic analysis approach, we developed three overarching themes. Military as family explored how many veterans experienced the military environment as a "family" that took care of them and provided structure. Normal is alien encompassed many veterans experiences of disconnection from people at home, lack of support from institutions, lack of structure, and loss of purpose upon return to civilian life. Searching for a new normal included strategies and supports veterans found to reconnect in the face of these challenges. A veteran who had successfully transitioned and provided support and advice as a peer navigator was frequently discussed as a key resource. A minority of respondents-those who were mistreated by the military system, women veterans, and veterans recovering from substance abuse problems-were less able to access peer support. Other reconnection strategies included becoming an ambassador to the military experience, and knowing transition challenges would ease with time. Results were consistent with and are discussed in the context of homecoming theory and social climate theory. Social support is known to be protective for veterans, but our findings add the nuance of substantial obstacles veterans face in locating and accessing support, due to disconnection and unsupportive institutions. Larger scale work is needed to better understand how to foster peer connection, build reconnection with family, and engage the broader community to understand and support veterans; interventions to support reconnection for veterans should be developed.

The future of breast cancer systemic therapy: the next 10 years.

2015-02-01

Over the past 50 years, substantial progress has been made in the systemic treatment of early-stage and advanced breast cancer. The use of chemotherapy in the adjuvant and metastatic settings has demonstrated proven efficacy and it has been clearly demonstrated that targeting the estrogen receptor and human growth factor receptor 2 (HER2) is efficacious in early and advanced disease. Despite these advances, vexing clinical challenges remain particularly related to the treatment of triple-negative breast cancer (TNBC; estrogen receptor [ER]-negative, progesterone receptor [PR]-negative, and HER2-negative) where little progress has been made therapeutically in more than a decade. While recurrences of hormone-responsive breast cancer are overall less common, late relapses after cessation of endocrine therapy are a more frequent occurrence in modern times and reflect the problem of underlying tumor dormancy that as yet has not been overcome. Multiple molecular tools are now available to interrogate the biology of breast cancer, though exactly how to make this information meaningful in the clinic has proven challenging, and molecularly driven clinical trials have faced feasibility challenges. In parallel, focus has expanded from tumor to host with the ability to ascertain underlying germline alterations, such as inherited BRCA1 and BRCA2 mutations, which may be responsible for breast cancer carcinogenesis and, importantly, may have implications for treatment. These clinical advances in germline genetics, made possible by both scientific investigation as well as the courts, still face challenges related to increasing encounters with variants of unknown significance and difficulty in predicting risks associated with less well-characterized inherited cancer predisposition syndromes. In this paper, we attempt to predict the next 10 years of breast cancer, in particular focusing on how the past serves as prologue to the future in this disease.

Faces in Context: A Review and Systematization of Contextual Influences on Affective Face Processing

PubMed Central

Wieser, Matthias J.; Brosch, Tobias

2012-01-01

Facial expressions are of eminent importance for social interaction as they convey information about other individuals’ emotions and social intentions. According to the predominant “basic emotion” approach, the perception of emotion in faces is based on the rapid, automatic categorization of prototypical, universal expressions. Consequently, the perception of facial expressions has typically been investigated using isolated, de-contextualized, static pictures of facial expressions that maximize the distinction between categories. However, in everyday life, an individual’s face is not perceived in isolation, but almost always appears within a situational context, which may arise from other people, the physical environment surrounding the face, as well as multichannel information from the sender. Furthermore, situational context may be provided by the perceiver, including already present social information gained from affective learning and implicit processing biases such as race bias. Thus, the perception of facial expressions is presumably always influenced by contextual variables. In this comprehensive review, we aim at (1) systematizing the contextual variables that may influence the perception of facial expressions and (2) summarizing experimental paradigms and findings that have been used to investigate these influences. The studies reviewed here demonstrate that perception and neural processing of facial expressions are substantially modified by contextual information, including verbal, visual, and auditory information presented together with the face as well as knowledge or processing biases already present in the observer. These findings further challenge the assumption of automatic, hardwired categorical emotion extraction mechanisms predicted by basic emotion theories. Taking into account a recent model on face processing, we discuss where and when these different contextual influences may take place, thus outlining potential avenues in future research.

What we can and cannot (yet) do with functional near infrared spectroscopy

PubMed Central

Strait, Megan; Scheutz, Matthias

2014-01-01

Functional near infrared spectroscopy (NIRS) is a relatively new technique complimentary to EEG for the development of brain-computer interfaces (BCIs). NIRS-based systems for detecting various cognitive and affective states such as mental and emotional stress have already been demonstrated in a range of adaptive human–computer interaction (HCI) applications. However, before NIRS-BCIs can be used reliably in realistic HCI settings, substantial challenges oncerning signal processing and modeling must be addressed. Although many of those challenges have been identified previously, the solutions to overcome them remain scant. In this paper, we first review what can be currently done with NIRS, specifically, NIRS-based approaches to measuring cognitive and affective user states as well as demonstrations of passive NIRS-BCIs. We then discuss some of the primary challenges these systems would face if deployed in more realistic settings, including detection latencies and motion artifacts. Lastly, we investigate the effects of some of these challenges on signal reliability via a quantitative comparison of three NIRS models. The hope is that this paper will actively engage researchers to acilitate the advancement of NIRS as a more robust and useful tool to the BCI community. PMID:24904261

Higher Throughput Calorimetry: Opportunities, Approaches and Challenges

PubMed Central

Recht, Michael I.; Coyle, Joseph E.; Bruce, Richard H.

2010-01-01

Higher throughput thermodynamic measurements can provide value in structure-based drug discovery during fragment screening, hit validation, and lead optimization. Enthalpy can be used to detect and characterize ligand binding, and changes that affect the interaction of protein and ligand can sometimes be detected more readily from changes in the enthalpy of binding than from the corresponding free-energy changes or from protein-ligand structures. Newer, higher throughput calorimeters are being incorporated into the drug discovery process. Improvements in titration calorimeters come from extensions of a mature technology and face limitations in scaling. Conversely, array calorimetry, an emerging technology, shows promise for substantial improvements in throughput and material utilization, but improved sensitivity is needed. PMID:20888754

2002-11-30

While transfusion-transmissible diseases, including AIDS and viral hepatitis, continue to spread especially in developing countries, the issue of safeguarding the world's blood supply is of paramount importance. China houses more than 20% of the earth's population, and thus its blood supply has the potential to affect the global community. In recent years, Chinese blood centres have tried to improve the nation's blood safety. Although substantial progress has already been made, many daunting difficulties remain. Traditional cultural barriers need to be overcome to successfully mobilise volunteer blood donors. Gaps in information and technology still need to be closed. Insufficiency of economic resources also restrict the blood bank industry. Other developing countries face many of the same challenges as China.

Regenerative nanomedicines: an emerging investment prospective?

PubMed Central

Prescott, Catherine

2010-01-01

Cells respond to their structural surrounding and within nanostructures exhibit unique proliferative and differentiation properties. The application of nanotechnologies to the field of regenerative medicine offers the potential to direct cell fate, target the delivery of cells and reduce immune rejection (via encapsulation), thereby supporting the development of regenerative medicines. The overall objective of any therapy is the delivery of the product not just into the clinic but also to patients on a routine basis. Such a goal typically requires a commercial vehicle and substantial levels of investment in scientific, clinical, regulatory and business expertise, resources, time and funding. Therefore, this paper focuses on some of the challenges facing this emerging industry, including investment by the venture capital community. PMID:20826478

Human brain structure predicts individual differences in preconscious evaluation of facial dominance and trustworthiness

PubMed Central

Kanai, Ryota; Bahrami, Bahador; Rees, Geraint

2015-01-01

Social cues conveyed by the human face, such as eye gaze direction, are evaluated even before they are consciously perceived. While there is substantial individual variability in such evaluation, its neural basis is unknown. Here we asked whether individual differences in preconscious evaluation of social face traits were associated with local variability in brain structure. Adult human participants (n = 36) monocularly viewed faces varying in dominance and trustworthiness, which were suppressed from awareness by a dynamic noise pattern shown to the other eye. The time taken for faces to emerge from suppression and become visible (t2e) was used as a measure of potency in competing for visual awareness. Both dominant and untrustworthy faces resulted in slower t2e than neutral faces, with substantial individual variability in these effects. Individual differences in t2e were correlated with gray matter volume in right insula for dominant faces, and with gray matter volume in medial prefrontal cortex, right temporoparietal junction and bilateral fusiform face area for untrustworthy faces. Thus, individual differences in preconscious social processing can be predicted from local brain structure, and separable correlates for facial dominance and untrustworthiness suggest distinct mechanisms of preconscious processing.

A variable nozzle for a turbocharger includes a plurality of vanes rotatably mounted on a nozzle ring and disposed in a nozzle flow path defined between the nozzle ring and an opposite nozzle wall. Either or both of the faces of the nozzle ring and nozzle wall include(s) at least one step that defines sealing surfaces positioned to be substantially abutted by airfoil surfaces of the vanes in the closed position of the vanes and to be spaced from the airfoil surfaces in positions other than the closed position. This substantial abutment between the airfoil surfaces and the sealing surfacesmore » serves to substantially prevent exhaust gas from leaking past the ends of the airfoil portions. At the same time, clearances between the nozzle ring face and the end faces of the airfoil portions can be sufficiently large to prevent binding of the vanes under all operating conditions.« less

Minimally Invasive Surgery in Gastrointestinal Cancer: Benefits, Challenges, and Solutions for Underutilization

PubMed Central

Gusani, Niraj J.; Kimchi, Eric T.; Kavic, Stephen M.

2014-01-01

Background and Objectives: After the widespread application of minimally invasive surgery for benign diseases and given its proven safety and efficacy, minimally invasive surgery for gastrointestinal cancer has gained substantial attention in the past several years. Despite the large number of publications on the topic and level I evidence to support its use in colon cancer, minimally invasive surgery for most gastrointestinal malignancies is still underused. Methods: We explore some of the challenges that face the fusion of minimally invasive surgery technology in the management of gastrointestinal malignancies and propose solutions that may help increase the utilization in the future. These solutions are based on extensive literature review, observation of current trends and practices in this field, and discussion made with experts in the field. Results: We propose 4 different solutions to increase the use of minimally invasive surgery in the treatment of gastrointestinal malignancies: collaboration between surgical oncologists/hepatopancreatobiliary surgeons and minimally invasive surgeons at the same institution; a single surgeon performing 2 fellowships in surgical oncology/hepatopancreatobiliary surgery and minimally invasive surgery; establishing centers of excellence in minimally invasive gastrointestinal cancer management; and finally, using robotic technology to help with complex laparoscopic skills. Conclusions: Multiple studies have confirmed the utility of minimally invasive surgery techniques in dealing with patients with gastrointestinal malignancies. However, training continues to be the most important challenge that faces the use of minimally invasive surgery in the management of gastrointestinal malignancy; implementation of our proposed solutions may help increase the rate of adoption in the future.

The organization of organ procurement.

PubMed

Prottas, J M

1989-01-01

The American organ procurement system has improved and matured in the last five years. At the same time, the basic challenges facing it have remained substantially the same because the moral and legal framework of the system has not changed. Success at organ procurement continues to depend on the voluntary cooperation of medical professionals and the families of potential organ donors. The generosity of the American public is so great that the primary challenge facing organ procurement agencies is obtaining cooperation from hospitals and medical professionals. This calls for a "marketing" orientation aimed at those hospitals and professionals who are most likely to treat potential donors. The last five years have seen a more general acceptance of this appreciation of the central task of organ procurement. As a result, the overall effectiveness of the system has improved, as measured by the number of organs procured on a per capita basis and by the number of multiorgan donors obtained. Much of this improvement can be attributed to the diffusion of organizational techniques and approaches, and this diffusion has been encouraged by the involvement of national organizations and public bodies in the organ procurement community. The system remains uneven in its effectiveness and further improvement is possible. It is also possible that the next general round of improvement will result from the application of businesslike information management and marketing techniques.

Facial Attractiveness Ratings from Video-Clips and Static Images Tell the Same Story

2011-01-01

Most of what we know about what makes a face attractive and why we have the preferences we do is based on attractiveness ratings of static images of faces, usually photographs. However, several reports that such ratings fail to correlate significantly with ratings made to dynamic video clips, which provide richer samples of appearance, challenge the validity of this literature. Here, we tested the validity of attractiveness ratings made to static images, using a substantial sample of male faces. We found that these ratings agreed very strongly with ratings made to videos of these men, despite the presence of much more information in the videos (multiple views, neutral and smiling expressions and speech-related movements). Not surprisingly, given this high agreement, the components of video-attractiveness were also very similar to those reported previously for static-attractiveness. Specifically, averageness, symmetry and masculinity were all significant components of attractiveness rated from videos. Finally, regression analyses yielded very similar effects of attractiveness on success in obtaining sexual partners, whether attractiveness was rated from videos or static images. These results validate the widespread use of attractiveness ratings made to static images in evolutionary and social psychological research. We speculate that this validity may stem from our tendency to make rapid and robust judgements of attractiveness. PMID:22096491

Strategies for carbohydrate model building, refinement and validation

PubMed Central

2017-01-01

Sugars are the most stereochemically intricate family of biomolecules and present substantial challenges to anyone trying to understand their nomenclature, reactions or branched structures. Current crystallographic programs provide an abstraction layer allowing inexpert structural biologists to build complete protein or nucleic acid model components automatically either from scratch or with little manual intervention. This is, however, still not generally true for sugars. The need for carbohydrate-specific building and validation tools has been highlighted a number of times in the past, concomitantly with the introduction of a new generation of experimental methods that have been ramping up the production of protein–sugar complexes and glycoproteins for the past decade. While some incipient advances have been made to address these demands, correctly modelling and refining carbohydrates remains a challenge. This article will address many of the typical difficulties that a structural biologist may face when dealing with carbohydrates, with an emphasis on problem solving in the resolution range where X-ray crystallography and cryo-electron microscopy are expected to overlap in the next decade.

Impressive advances in neonatology have occurred over the 30 years of life of The Eunice Kennedy Shriver National Institute of Child Health and Human Development Neonatal Research Network (NRN). However, substantial room for improvement remains in investigating and further developing the evidence base for improving outcomes among the extremely premature. We discuss some of the specific methodological challenges in the statistical design and analysis of randomized trials and observational studies in this population. Challenges faced by the NRN include designing trials for unusual or rare outcomes, accounting for and explaining center variations, identifying other subgroup differences, and balancing safety and efficacy concerns between short-term hospital outcomes and longer-term neurodevelopmental outcomes. In conclusion, the constellation of unique patient characteristics in neonates calls for broad understanding and careful consideration of the issues identified in this article for conducting rigorous studies in this population.

Participation in the Paralympic Games has grown substantially, yet the same growth and development has not occurred with empirical literature for coaching in disability sport. The purpose of the current study was to explore Paralympic coaches' perceptions of their learning and educational experiences, including their formal and informal mentoring opportunities. Six highly successful and experienced Paralympic coaches were individually interviewed in this qualitative study. The interview data were analyzed following Braun and Clarke's guidelines for thematic analysis. Results demonstrated that Paralympic coaches faced several challenges to acquire disability specific coaching knowledge and skills. These challenges led the participants to utilize an array of informal learning situations, such as actively seeking mentoring relationships when they first entered the field. After becoming expert coaches, they gave back to their sport by making mentoring opportunities available for aspiring coaches. The results of the current study address the value and importance of mentoring as a structured source of education and career development for aspiring Paralympic coaches. Crown Copyright © 2016.

Today's educators are faced with substantial challenges in the use of information technology for anaesthesia training and continuing medical education. Millennial learners have uniquely different learning styles than previous generations of students. These preferences distinctly incorporate the use of digital information technologies and social technologies to support learning. To be effective teachers, modern educators must be familiar with these new information technologies and understand how to use them for medical education. Examples of new information technologies include learning management systems, lecture capture, social media (YouTube, Flickr), social networking (Facebook), Web 2.0, multimedia (video learning triggers and point-of-view video) and mobile computing applications. The information technology challenges for educators in the twenty-first century include: (a) understanding how technology shapes the learning preferences of today's anaesthesia residents, (b) distinguishing between the function and properties of new learning technologies and (c) properly using these learning technologies to enhance the anaesthesia curriculum.

Significant advances in perinatal and neonatal medicine over the last 20 years and the recent emergence of fetal surgery has resulted in anesthesia providers caring for a growing number of infants born at the margin of viability. Anesthetic management in this patient population has to take into consideration the immature function of many vital organ systems as well as the effects of the underlying disease processes, which can frequently lead to severe physiological derangements. Accordingly, premature infants presenting for major surgeries early in life can represent a significant anesthetic challenge. However, even with advanced anesthetic and surgical management and optimal intensive care, extremely premature infants face substantial postoperative morbidity and mortality, as well as prolonged hospital courses. In this article, we will discuss the following questions: How far have we come in improving outcomes of extreme prematurity? And what will the future medical and societal challenges be, as we continue to redefine the limits of viability? © 2011 Blackwell Publishing Ltd.

Left ventricular assist device (LVAD) therapy has emerged as an increasingly vital facet of the treatment algorithm for advanced heart failure. Growing experience with LVAD support has led to substantial improvements in outcomes, with 1-year survival rates approaching that of cardiac transplantation. These therapeutic refinements have engendered growing interests in the potential for expanding the clinical indications for LVAD therapy to patients with less advanced heart failure. The primary obstacles to this evolution of care center largely on the prevention and/or management of the adverse events associated with LVAD therapy along with patient preference. Many programs also face the mounting difficulty of balancing quality outcomes with the increased volume of implants. During the recently assembled Users Meeting organized by St. Jude Medical, heart failure clinicians from nearly 50 LVAD implanting centers discussed these and other challenges and controversies impacting the field. The present review summarizes the key insights gleaned from this meeting. Copyright © 2018 Elsevier Inc. All rights reserved.

Spurred by the publication of Massachusetts Institute of Technology OpenCourseWare in 2002, the open educational resources (OER) movement, which has rapidly expanded and captured the imagination and energy of millions of creators and users throughout the world, now faces many opportunities and substantial challenges as it moves to become an integral part of the world's educational environment. The confluence of the Web and a spirit of sharing intellectual property have fueled a worldwide movement to make knowledge and education materials open to all for use. OER are content (courses, books, lesson plans, articles, etc.), tools (virtual laboratories, simulations, and games), and software that support learning and educational practice. OER are free on the Web, and most have licenses that allow copyright holders to retain ownership while providing specified rights for use in original and modified forms. At the least, OER have helped to level the distribution of knowledge across the world. A second promise of OER is to help transform educational practices. This article explores the history of and promises and challenges for OER.

New scientific knowledge, technology and creative minds are the main ingredients in order to reach out for this great opportunity. Efficiency all the way from breeding and farming to processing and dispatch is crucial for success. Technology has brought us far, and there is still a huge potential for increased efficiency by implementing best practices on a global scale. New challenges include: hyper flexible automation, more accurate and faster measurement systems and meeting special consumer demands already at the production line. Systems for optimal animal welfare will be even more important and sustainability is no longer a consumer trend but a license to operate.

The intention is to summarize the body of evidence speaking to the psychological challenges faced by visually impaired older adults, as well as their coping efforts. This evidence is substantiated by a rich set of concepts, theories, and empirical findings that have accumulated under the umbrella of age-related psychoophthalmology (APO). I introduce the field of APO and continue with a discussion of important concepts and theories for a better understanding of adaptational processes in visually impaired older adults. I then summarize the most relevant and most recent data from four areas: (1) everyday competence, (2) cognitive functioning, (3) social functioning, and (4) subjective well-being-related outcomes, depression, and adaptational processes. Thereafter, major insights related to the current state-of-the art psychosocial interventions with visuallyimpaired older adults are reviewed.

Roux, Brianna M; Cheng, Ming-Huei; Brey, Eric M

2015-01-01

Vascularization remains one of the most important challenges that must be overcome for tissue engineering to be consistently implemented for reconstruction of large volume bone defects. An extensive vascular network is needed for transport of nutrients, waste and progenitor cells required for remodelling and repair. A variety of tissue engineering strategies have been investigated in an attempt to vascularize tissues, including those applying cells, soluble factor delivery strategies, novel design and optimization of bio-active materials, vascular assembly pre-implantation and surgical techniques. However, many of these strategies face substantial barriers that must be overcome prior to their ultimate translation into clinical application. In this review recent progress in engineering vascularized bone will be presented with an emphasis on clinical feasibility. PMID:25877690

Capital investment strategies in health care systems.

PubMed

Reiter, K L; Smith, D G; Wheeler, J R; Rivenson, H L

2000-01-01

Capital investment decisions are among the most important decisions made by firms. They determine the firm's capacity for providing services and commit the firm's cash for an extended period of time. Interviews with chief financial officers of leading health care systems reveal capital investment strategies that generally follow the recommendations of modern finance theory. Still, there is substantial variation in capital budgeting techniques, methods of risk adjustment, and the importance of qualitative considerations in investment decision making. There is also variation in delegation of investment decision making to operating units and methods of performance evaluation. Health care systems face the same challenges as other organizations in developing and implementing capital investment strategies that use consistent methods for evaluation of projects that have inconsistent aims and outcomes.

Safety and ergonomic considerations for an aging workforce in the US construction industry.

Choi, Sang D

2009-01-01

The US construction workforce is aging as millions of baby boomers move toward retirement age. Older workers make a substantial contribution to construction in terms of skills and experience. However, construction is still one of the most physically demanding occupations, hence the health implications for older workers. Descriptions of injuries, illnesses and fatalities among older workers in the US construction industry from recent literature are presented along with the practical health and safety interventions that have been proposed including: ergonomic interventions, wellness programs, worksite housekeeping, training, and safety climate. Understanding the risks and hazards in specific industries could help identify training and intervention requirements to meet the challenges facing aging workers in these occupational groups.

The upsurge in the uptake of antiretroviral therapy (ART) has led to a significant increase in the survival of vertically acquired HIV infected children, many of whom are currently living into adolescence and early adulthood. However little if anything is known of the lived experiences and the challenges faced by HIV positive adolescents in the African context. We set out to investigate psychosocial challenges faced by HIV infected adolescents on the Kenyan coast. A total of 44 participants (12 HIV-infected adolescents, 7 HIV uninfected adolescents, and 25 key informants) took part in this qualitative study, using individually administered in-depth interviews. A framework approach was used to analyze the data using NVIVO software. We observed that the challenges faced by adolescents in rural Kenya could be placed into six major themes: poverty, poor mental and physical health, the lack of a school system that is responsive to their needs, challenges in how to disclose to peers and family members, high levels of stigma in its various forms, and challenges of medical adherence leading to the need for close monitoring. In this African community, vertically acquired HIV-infected adolescents face a complex set of social, economic and medical challenges. Our study points to the urgent need to develop multisectorial intervention support programmes to fully address these challenges.

Lessons from forest FACE experiments provide guidance for Amazon-FACE science plan (Invited)

NASA Astrophysics Data System (ADS)

Norby, R. J.; Lapola, D. M.

2013-12-01

Free-air CO2 enrichment (FACE) experiments have provided novel insights into the ecological mechanisms controlling the cycling and storage of carbon in terrestrial ecosystems, and they provide a strong foundation for next-generation experiments in unexplored biomes. Specific lessons from FACE experiments include: (1) Carbon cycle responses are time-dependent because component processes have different rate constants: for example, net primary productivity is increased by elevated CO2, but the response may diminish with time as N cycling feedbacks become important. (2) Carbon partitioning patterns determine the fate of the extra C taken up by CO2-enriched plants, but partitioning responses remain an important challenge for ecosystem models. (3) The influence of N cycling on plant and ecosystem C cycling continues to be a critical uncertainty, and new experiments, especially in the tropics, must also consider P cycling. (4) Plant community structure can influence the ecosystem response to elevated CO2, but dynamic vegetation effects have not been adequately addressed. These experiences from FACE experiments in temperate forests are now guiding the development of a science plan for a FACE experiment in Amazonia. Models and small-scale experimental results agree that elevated CO2 will affect the metabolism of tropical ecosystems, but the qualitative and quantitative expression of the effects are largely unknown, representing a major source of uncertainty that limits our capacity to assess the vulnerability of the Amazon forest to climate change. Recognizing the high importance of the forests of the Amazon basin on global carbon, water, and energy cycles, biodiversity conservation, and the provision of essential services in Latin America, a consortium of Brazilian researchers and international collaborators have developed a science plan for Amazon-FACE. While the challenges presented both by infrastructure needs (roads, electricity, and provision of CO2) and biology (the size and diversity of the forest) are substantial, preliminary evaluation and past experience from temperate forest FACE experiments have supported the feasibility of an experiment comprising replicated 30-m diameter FACE plots in primary forest. The proposed site is the ZF2 research area 60 km north of Manaus and administered by Brazil's National Institute for Amazonia Research (INPA). The vegetation is representative of a dominant fraction of the forests occurring in the Amazon basin: old-growth closed-canopy terra firme (non-flooded) forest with trees 30-35 m in height on well drained clay soils. The major science questions guiding the experiment are closely informed by results of past FACE experiment and involve carbon metabolism, water use, nutrient cycling, interactions with environmental stressors, and the relationship between plant functional traits and community composition. FACE experiments can define ecological processes and mechanisms of responses for predictive models of ecosystem response, and models of CO2 response can define critical uncertainties and testable hypotheses for experiments; hence, the Amazon FACE experiment will feature a close integration of modeling and experimental approaches.

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.

The Invisible Army

2017-01-01

ABSTRACT The “invisible army” of clinical microbiologists is facing major changes and challenges. The rate of change in both the science and technology is accelerating with no end in sight, putting pressure on our army to learn and adapt as never before. Health care funding in the United States is undergoing dramatic change which will require a new set of assumptions about how clinical microbiology is practiced here. A major challenge facing the discipline is the replacement of a generation of clinical microbiologists. In my opinion, it is incumbent on us in the invisible army to continue to work with the American Society for Microbiology (ASM) in meeting the future challenges faced by our discipline. In this commentary, I will first discuss some recent history of clinical microbiology within ASM and then some current challenges we face. PMID:28659316

Challenges in the management of community pharmacies in Malaysia

PubMed Central

2017-01-01

Background: The provision of professional pharmacy services by community pharmacists continues to be limited, particularly in low and middle income countries. It was postulated that multiple management challenges faced by community pharmacists contribute to this situation. Objective: The primary aim of the research was to determine the challenges faced in the management of community pharmacies in Sarawak (the largest state in Malaysia), and practical strategies to cope and overcome the challenges. Methods: Semi-structured interviews were carried out with community pharmacists practising in Sarawak. Purposive and snowball sampling were employed to ensure a diverse group of informants. The interviews were audio-recorded and transcribed verbatim, with the resultant data analysed using thematic analysis. Data collection, coding, interpretation were carried out iteratively until theoretical saturation. Results: Twenty respondents from different demographic characteristics were recruited. Six major themes were identified. Management challenges faced by community pharmacists traverse five major domains: market competition, legislative issues, customers’ knowledge and expectations, macroeconomic impacts and operational challenges. Most of these challenges require government intervention to be resolved. In the meantime, improving customer service and expanding the range of professional services were seen as the most viable strategies to cope with existing challenges. The main concern is that current legislative and economic landscape may hinder these strategies. Enactment of dispensing separation and more protective measures against market competition were suggested to alleviate the challenges faced. Conclusion: Numerous management challenges faced by community pharmacists that distract them from delivering professional pharmacy services have been highlighted. Urgent affirmative actions by the government are warranted in supporting community pharmacists to realise and maximise their potentials. PMID:28690697

Breastfeeding--anti-viral potential and relevance to the influenza virus pandemic.

PubMed

Prameela, K K

2011-06-01

Essential nutritive and immunological ingredients abundantly present in breastmilk make it the choice infant nutrition. The uniqueness of mother's milk, in contrast to most therapeutics and immunizations, lies in its potential to adapt itself to the requirements of the infant so that timely immune defenses are tapped from its constituents by immune regulation, modulation and immune acceleration to stimulate novel substances; these render it pertinent as defense when faced with challenging organisms. While it is appreciated that immunity can be transferred from mother to infant through breastmilk following maternal influenza vaccination, the immense benefits conferred by breastfeeding per se during influenza pandemics may not be fully valued. This is substantiated by debates and ambiguities for continued breastfeeding in the face of maternal influenza infections. This article emphasises the utmost importance of breastfeeding in viral pandemics in the light of the changing immunological strategies used by viruses at different times and the urgent need for such opportune defenses. The prolific interaction of its constituents is frequently understated as enormous advantages to the suckling infant.

The provision of appropriate waste management is not only an indicator of development but also of broader sustainability. This is particularly relevant to expanding cities in developing countries faced with rising waste generation and associated environmental health problems. Despite these urgent issues, city authorities often lack the evidence required to make well-informed decisions. This study evaluates the carbon and economic performance of low-carbon measures in the waste sector at a city level, within the context of a developing country. Palembang in Indonesia is used as a case of a medium-sized city in a newly industrialized country, with relevance to other similar cities in the developing world. Evidence suggests that the waste sector can achieve substantial carbon emission reductions, and become a carbon sink, in a cost effective way. Hence there is an economic case for a low carbon development path for Palembang, and possibly for other cities in developing and developed countries facing similar challenges.

The effects of obesity on doctor-diagnosed chronic diseases in Africa: empirical results from Senegal and South Africa.

PubMed

Asfaw, Abay

2006-01-01

While inadequate food and communicable infectious diseases have been a concern of researchers and policy makers in Africa, little attention has been given to obesity and chronic, non-communicable diseases. Africa is not usually associated with obesity and chronic diseases. Yet there has been a sharp rise in the incidence of obesity and chronic diseases, a major public health problem in many countries. The paper examines the impact of obesity on the prevalence of four doctor-diagnosed chronic diseases in Senegal and South Africa. The results reveal that obese respondents were 4.7, 2.8, and 4.8% more likely to face the risks of arthritis, diabetes, and heart diseases in South Africa and 6.5 and 7.4% more likely to face the risks of heart disease and asthma in Senegal than their lean counterparts. Obesity imposes a real and substantial danger, affecting the prevalence of chronic diseases. Unchecked it can be a major public health problem, impose a serious challenge to the health sector, and can jeopardize future developments.

Ethics of physiotherapy practice in terminally ill patients in a developing country, Nigeria.

2015-12-01

Physiotherapy has been widely defined as a healthcare profession that assesses, diagnoses, treats, and works to prevent disease and disability through physical means. The World Confederation for Physical Therapy describes physiotherapy as providing services to people and populations to develop, maintain, and restore maximum movement and functional ability throughout the lifespan. Physiotherapists working with terminally ill patients face a myriad of ethical issues which have not been substantially discussed in bioethics especially in the African perspective. In the face of resource limitation in developing countries, physiotherapy seems to be a cost-effective means of alleviating pain and distressing symptoms at the end-of-life, ensuring a more dignified passage from life to death, yet referrals to physiotherapy are not timely. Following extensive literature search using appropriate keywords, six core ethical themes related to physiotherapy in terminally ill patients were identified and using the four principles of bioethics (patient's autonomy, beneficence, nonmaleficence, and justice), an ethical analysis of these themes was done to highlight the ethical challenges of physiotherapists working in a typical African setting such as Nigeria.

Understanding the mechanisms of unconscious processing is one of the most substantial endeavors of cognitive science. While there are many different empirical ways to address this question, the use of faces in such research has proven exceptionally fruitful. We review here what has been learned about unconscious processing through the use of faces and face-selective neural correlates. A large number of cognitive systems can be explored with faces, including emotions, social cueing and evaluation, attention, multisensory integration, and various aspects of face processing.

Promises and challenges in solid-state lighting

NASA Astrophysics Data System (ADS)

Schubert, Fred

2010-03-01

Lighting technologies based on semiconductor light-emitting diodes (LEDs) offer unprecedented promises that include three major benefits: (i) Gigantic energy savings enabled by efficient conversion of electrical energy to optical energy; (ii) Substantial positive contributions to sustainability through reduced emissions of global-warming gases, acid-rain gases, and toxic substances such as mercury; and (iii) The creation of new paradigms in lighting driven by the unique controllability of solid-state lighting sources. Due to the powerful nature of these benefits, the transition from conventional lighting sources to solid-state lighting is virtually assured. This presentation will illustrate the new world of lighting and illustrate the pervasive changes to be expected in lighting, displays, communications, and biotechnology. The presentation will also address the formidable challenges that must be addressed to continue the further advancement of solid-state lighting technology. These challenges offer opportunities for research and innovation. Specific challenges include light management, carrier transport, and optical design. We will present some innovative approaches in order to solve known technical challenges faced by solid-state lighting. These approaches include the demonstration and use of new optical thin-film materials with a continuously tunable refractive index. These approaches also include the use of polarization-matched structures that reduce the polarization fields in GaInN LEDs and the hotly debated efficiency droop, that is, the decreasing LED efficiency at high currents.

PEACH™QLD translated the PEACH™ Program, designed to manage overweight/obesity in primary school-aged children, from efficacious RCT and small scale community trial to a larger state-wide program. This paper describes the lessons learnt when upscaling to universal health coverage. The 6-month, family-focussed program was delivered in Queensland, Australia from 2013 to 2016. Its implementation was planned by researchers who developed the program and conducted the RCT, and experienced project managers and practitioners across the health continuum. The intervention targeted parents as the agents of change and was delivered via parent-only group sessions. Concurrently, children attended fun, non-competitive activity sessions. Sessions were delivered by facilitators who received standardised training and were employed by a range of service providers. Participants were referred by health professionals or self-referred in response to extensive promotion and marketing. A pilot phase and a quality improvement framework were planned to respond to emerging challenges. Implementation challenges included engagement of the health system; participant recruitment; and engagement. A total of 1513 children (1216 families) enrolled, with 1122 children (919 families) in the face-to-face program (105 groups in 50 unique venues) and 391 children (297 families) in PEACH™ Online. Self-referral generated 68% of enrolments. Unexpected, concurrent and, far-reaching public health system changes contributed to poor program uptake by the sector (only 56 [53%] groups delivered by publicly-funded health organisations) requiring substantial modification of the original implementation plan. Process evaluation during the pilot phase and an ongoing quality improvement framework informed program adaptations that included changing from fortnightly to weekly sessions aligned with school terms, revision of parent materials, modification of eligibility criteria to include healthy weight children and provision of services privately. Comparisons between pilot versus state-wide waves showed comparable prevalence of families not attending any sessions (25% vs 28%) but improved number of sessions attended (median = 5 vs 7) and completion rates (43% vs 56%). Translating programs developed in the research context to enable implementation at scale is complex and presents substantial challenges. Planning must ensure there is flexibility to accommodate and proactively manage the system changes that are inevitable over time. ACTRN12617000315314 .

Introduction 5 billion people around the world do not have access to safe, affordable, timely surgical care. This series of qualitative interviews was launched by The Lancet Commission on Global Surgery (LCoGS) with the aim of understanding the contextual challenges—the specific circumstances—faced by surgical care providers in low-resource settings who care for impoverished patients, and how those providers overcome these challenges. Methods From January 2014 to February 2015, 20 LCoGS collaborators conducted semistructured interviews with 148 surgical providers in low-resource settings in 21 countries. Stratified purposive sampling was used to include both rural and urban providers, and reputational case selection identified individuals. Interviewers were trained with an implementation manual. Following immersion into de-identified texts from completed interviews, topical coding and further analysis of coded texts was completed by an independent analyst with periodic validation from a second analyst. Results Providers described substantial financial, geographic and cultural barriers to patient access. Rural surgical teams reported a lack of a trained workforce and insufficient infrastructure, equipment, supplies and banked blood. Urban providers face overcrowding, exacerbated by minimal clinical and administrative support, and limited interhospital care coordination. Many providers across contexts identified national health policies that do not reflect the realities of resource-poor settings. Some findings were region-specific, such as weak patient–provider relationships and unreliable supply chains. In all settings, surgical teams have created workarounds to deliver care despite the challenges. Discussion While some differences exist between countries, the barriers to safe surgery and anaesthesia are overall consistent and resource-dependent. Efforts to advance and expand global surgery must address these commonalities, while local policymakers can tailor responses to key contextual differences. PMID:28588976

The Square Kilometre Array (SKA) is a large science project planning to commence construction of the world's largest Radio Telescope after 2018. MeerKAT is one of the precursor projects to the SKA, based on the same site that will host the SKA Mid array in the central Karoo area of South Africa. From the perspective of signal processing hardware development, we analyse the challenges that MeerKAT encountered and extrapolate them to SKA in order to prepare the System Engineering and Project Management methods that could contribute to a successful completion of SKA. Using the MeerKAT Digitiser, Correlator/Beamformer and Time and Frequency Reference Systems as an example, we will trace the risk profile and subtle differences in engineering approaches of these systems over time and show the effects of varying levels of System Engineering rigour on the evolution of their risk profiles. It will be shown that the most rigorous application of System Engineering discipline resulted in the most substantial reduction in risk over time. Since the challenges faced by SKA are not limited to that of MeerKAT, we also look into how that translates to a system development where there is substantial complexity in both the created system as well as the creating system. Since the SKA will be designed and constructed by consortia made up from the ten member countries, there are many additional complexities to the organisation creating the system - a challenge the MeerKAT project did not encounter. Factors outside of engineering, for instance procurement models and political interests, also play a more significant role, and add to the project risks of SKA when compared to MeerKAT.

Young persons with visual impairment: challenges of participation.

PubMed

Salminen, Anna-Liisa; Karhula, Maarit E

2014-07-01

To describe the challenges to activity and participation faced by young people with visual impairment within the framework of the International Classification of Functioning (ICF). 14 young persons (aged 16-22 years) with visual impairment and their parents (n = 22) participated in the study. The Canadian Occupational Performance Measure (COPM) was used to describe challenges of participation as perceived by the young persons themselves. Individual interviews with the young persons and their parents were used to investigate in more depth the challenges the young persons face with regard to participation. Young persons with visual impairment face challenges to participation most frequently with regard to mobility, domestic life, interpersonal interaction and relationships, major life areas, and leisure activities. The environment in which they live has a central role as a barrier or facilitator of participation. The challenges related to activities and participation that young persons with visual impairment face are diverse. It is important that these challenges are assessed individually and with the help of subjective measures. Serving as a broad framework for classifying the data, the ICF proved to be a useful tool, but used strictly at category level it may limit the coding of data and narrow interpretation.

Becoming a nurse faculty leader: facing challenges through reflecting, persevering and relating in new ways.

PubMed

Horton-Deutsch, Sara; Young, Patricia K; Nelson, Kristine A

2010-05-01

The aim of the present study was to explore the experience of becoming a nurse faculty leader. In a recent interpretation of 23 interviews conducted with nurse faculty leaders from across the United States about their experiences of becoming a leader three themes were identified: being thrust into leadership, taking risks and facing challenges. This interpretive phenomenological study further explicates three aspects of how nurse educators faced challenges in becoming and serving as a leader. Facing challenges meant reflecting, persevering through difficulties and learning to relate to others in new ways. Exemplars of participant experiences are provided for concreteness, to assist readers in determining how findings resonate with their own experience and how they can actualize this resonance in their own leadership practice. In the present study, reflecting, persevering through difficulties and learning to relate with others in a new way was how leaders faced challenges. Leadership development opportunities that facilitate self-exploration, caring and thoughtful interactions with others and values clarification serve as the foundation for becoming a nurse faculty leader who is, in turn, able to build leadership capacity in other individuals and organizations.

Afghanistan and Iraq veterans experienced traumas during deployment, and disrupted connections with friends and family. In this context, it is critical to understand the nature of veterans’ transition to civilian life, the challenges navigated, and approaches to reconnection. We investigated these issues in a qualitative study, framed by homecoming theory, that comprised in-depth interviews with 24 veterans. Using an inductive thematic analysis approach, we developed three overarching themes. Military as family explored how many veterans experienced the military environment as a “family” that took care of them and provided structure. Normal is alien encompassed many veterans experiences of disconnection from people at home, lack of support from institutions, lack of structure, and loss of purpose upon return to civilian life. Searching for a new normal included strategies and supports veterans found to reconnect in the face of these challenges. A veteran who had successfully transitioned and provided support and advice as a peer navigator was frequently discussed as a key resource. A minority of respondents—those who were mistreated by the military system, women veterans, and veterans recovering from substance abuse problems—were less able to access peer support. Other reconnection strategies included becoming an ambassador to the military experience, and knowing transition challenges would ease with time. Results were consistent with and are discussed in the context of homecoming theory and social climate theory. Social support is known to be protective for veterans, but our findings add the nuance of substantial obstacles veterans face in locating and accessing support, due to disconnection and unsupportive institutions. Larger scale work is needed to better understand how to foster peer connection, build reconnection with family, and engage the broader community to understand and support veterans; interventions to support reconnection for veterans should be developed.

Objective studies of the face of Noonan, Cardio-facio-cutaneous, and Costello syndromes: A comparison of three disorders of the Ras/MAPK signaling pathway.

PubMed

Allanson, Judith E

2016-10-01

Noonan, Cardio-facio-cutaneous, and Costello syndromes are disorders of the Ras/MAPK pathway that share many clinical features. This observational and anthropometric study was conducted to describe the key facial features of each syndrome in order to improve discrimination between the three conditions, particularly in young children where diagnosis is most challenging. Direct measurement of the head and face was used to enhance diagnostic accuracy, and identify the most unusual or specific dimensions. The Noonan syndrome cohort included 123 individuals, aged 6 months to 41 years. There were 20 children and adolescents with Cardio-facio-cutaneous syndrome, and 28 individuals with Costello syndrome, aged 1-32 years. The facial phenotypes of these syndromes, particularly Noonan syndrome, are well-described but objective data have not been published in peer-reviewed literature. In this study, subjective observations, in the main, were validated by anthropometry with one exception. In individuals with Costello syndrome, mouth width was normal, thus the impression of wide mouth is likely due to full lips or the mouth being viewed in relation to a narrow lower face. When the three conditions were compared objectively, syndrome-specific pattern profiles showed high concordance in early life. At older ages, Cardio-facio-cutaneous syndrome was distinguished by increased width of the mid/lower face, and reduced growth of maxillary and mandibular dimensions was noted in both Noonan and Costello syndromes. Despite substantial similarities in face shape in older individuals with these two conditions, bulbous nasal tip, full lips, and an apparently wide mouth in those with Costello Syndrome facilitate discrimination from Noonan syndrome. © 2016 Wiley Periodicals, Inc. © 2016 Wiley Periodicals, Inc.

Prolonged Interruption of Cognitive Control of Conflict Processing Over Human Faces by Task-Irrelevant Emotion Expression

PubMed Central

Kim, Jinyoung; Kang, Min-Suk; Cho, Yang Seok; Lee, Sang-Hun

2017-01-01

As documented by Darwin 150 years ago, emotion expressed in human faces readily draws our attention and promotes sympathetic emotional reactions. How do such reactions to the expression of emotion affect our goal-directed actions? Despite the substantial advance made in the neural mechanisms of both cognitive control and emotional processing, it is not yet known well how these two systems interact. Here, we studied how emotion expressed in human faces influences cognitive control of conflict processing, spatial selective attention and inhibitory control in particular, using the Eriksen flanker paradigm. In this task, participants viewed displays of a central target face flanked by peripheral faces and were asked to judge the gender of the target face; task-irrelevant emotion expressions were embedded in the target face, the flanking faces, or both. We also monitored how emotion expression affects gender judgment performance while varying the relative timing between the target and flanker faces. As previously reported, we found robust gender congruency effects, namely slower responses to the target faces whose gender was incongruent with that of the flanker faces, when the flankers preceded the target by 0.1 s. When the flankers further advanced the target by 0.3 s, however, the congruency effect vanished in most of the viewing conditions, except for when emotion was expressed only in the flanking faces or when congruent emotion was expressed in the target and flanking faces. These results suggest that emotional saliency can prolong a substantial degree of conflict by diverting bottom-up attention away from the target, and that inhibitory control on task-irrelevant information from flanking stimuli is deterred by the emotional congruency between target and flanking stimuli.

Temporal Tuning of Word- and Face-selective Cortex.

PubMed

Yeatman, Jason D; Norcia, Anthony M

2016-11-01

Sensitivity to temporal change places fundamental limits on object processing in the visual system. An emerging consensus from the behavioral and neuroimaging literature suggests that temporal resolution differs substantially for stimuli of different complexity and for brain areas at different levels of the cortical hierarchy. Here, we used steady-state visually evoked potentials to directly measure three fundamental parameters that characterize the underlying neural response to text and face images: temporal resolution, peak temporal frequency, and response latency. We presented full-screen images of text or a human face, alternated with a scrambled image, at temporal frequencies between 1 and 12 Hz. These images elicited a robust response at the first harmonic that showed differential tuning, scalp topography, and delay for the text and face images. Face-selective responses were maximal at 4 Hz, but text-selective responses, by contrast, were maximal at 1 Hz. The topography of the text image response was strongly left-lateralized at higher stimulation rates, whereas the response to the face image was slightly right-lateralized but nearly bilateral at all frequencies. Both text and face images elicited steady-state activity at more than one apparent latency; we observed early (141-160 msec) and late (>250 msec) text- and face-selective responses. These differences in temporal tuning profiles are likely to reflect differences in the nature of the computations performed by word- and face-selective cortex. Despite the close proximity of word- and face-selective regions on the cortical surface, our measurements demonstrate substantial differences in the temporal dynamics of word- versus face-selective responses.

Cancer survivorship: challenges and changing paradigms.

We summarize the potential issues faced by cancer survivors, define a conceptual framework for cancer survivorship, describe challenges associated with improving the quality of survivorship care and outline proposed survivorship programs that may be implemented going forward. We performed a nonsystematic review of current cancer survivorship literature. Given the comprehensive scope and high profile, the recent report by the Institute of Medicine, From Cancer Patient to Cancer Survivor: Lost in Transition, served as the principal guide for the review. In recognition of the increasing number of cancer survivors in the United States survivorship has become an important health care concern. The recent report by the Institute of Medicine comprehensively outlined deficits in the care provided to cancer survivors, and proposed mechanisms to improve the coordination and quality of followup care for this increasing number of Americans. Measures to achieve these objectives include improving communication between health care providers through a survivorship care plan, providing evidence based surveillance guidelines and assessing different models of survivorship care. Implementing coordinated survivorship care broadly will require additional health care resources, and commitment from health care providers and payers. Research demonstrating the effectiveness of survivorship care will be important on this front. Potential shortcomings in the recognition and management of ongoing issues faced by cancer survivors may impact the overall quality of long-term care in this increasing population. Although programs to address these issues have been proposed, there is substantial work to be done in this area.

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.

Accurate and timely evaluation of dysphagia in children with cerebral palsy (CP) is critical. For children with limited access to quality healthcare, telehealth is an option; however, its reliability needs to be investigated. To test the reliability of an asynchronous telehealth model for evaluating dysphagia in children with CP using a standardized clinical assessment. Nineteen children (age range 6.9-17.5) were assessed at three mealtimes via the Dysphagia Disorder Survey (DDS) by three clinicians (face-to-face evaluations). Mealtimes were video-recorded to allow asynchronous evaluations by a remote clinician who also completed approximately 1/3 of face-to-face evaluations. Agreement was tested on DDS variables and dysphagia severity. Results revealed substantial to excellent agreement between face-to-face and remote assessments by the same rater (78-100%, KW=0.64-1) on all, but two variables (oral transport and oral pharyngeal swallow) and by different raters (69-89%, KW=0.6-0.86) on all but one variable (orienting). For dysphagia severity, intrarater agreement was excellent (100%, KW=1); interrater agreement was substantial (85%; KW=0.76). Asynchronous clinical swallowing evaluations using standardized tools have acceptable levels of agreement with face-to-face evaluations, and can be an alternative for children with limited access to expert swallowing care.

Flat or curved thin optical display panel

DOEpatents

Veligdan, J.T.

1995-01-10

An optical panel includes a plurality of waveguides stacked together, with each waveguide having a first end and an opposite second end. The first ends collectively define a first face, and the second ends collectively define a second face of the panel. The second face is disposed at an acute face angle relative to the waveguides to provide a panel which is relatively thin compared to the height of the second face. In an exemplary embodiment for use in a projection TV, the first face is substantially smaller in height than the second face and receives a TV image, with the second face defining a screen for viewing the image enlarged. 7 figures.

2009-09-01

Pharmaceutical research and development is facing substantial challenges that have prompted the industry to shift funding from early- to late-stage projects. Among the effects is a major change in the attitude of many companies to their internal bioinformatics resources: the focus has moved from the vigorous pursuit of intellectual property towards exploration of pre-competitive cross-industry collaborations and engagement with the public domain. High-quality, open and accessible data are the foundation of pre-competitive research, and strong public-private partnerships have considerable potential to enhance public data resources, which would benefit everyone engaged in drug discovery. In this article, we discuss the background to these changes and propose new areas of collaboration in computational biology and chemistry between the public domain and the pharmaceutical industry.

Resonant infrared detector with substantially unit quantum efficiency

1994-01-01

A resonant infrared detector includes an infrared-active layer which has first and second parallel faces and which absorbs radiation of a given wavelength. The detector also includes a first tuned reflective layer, disposed opposite the first face of the infrared-active layer, which reflects a specific portion of the radiation incident thereon and allows a specific portion of the incident radiation at the given wavelength to reach the infrared-active layer. A second reflective layer, disposed opposite the second face of the infrared-active layer, reflects back into the infrared-active layer substantially all of the radiation at the given wavelength which passes through the infrared-active layer. The reflective layers have the effect of increasing the quantum efficiency of the infrared detector relative to the quantum efficiency of the infrared-active layer alone.

Toward a Social Psychophysics of Face Communication.

PubMed

Jack, Rachael E; Schyns, Philippe G

2017-01-03

As a highly social species, humans are equipped with a powerful tool for social communication-the face. Although seemingly simple, the human face can elicit multiple social perceptions due to the rich variations of its movements, morphology, and complexion. Consequently, identifying precisely what face information elicits different social perceptions is a complex empirical challenge that has largely remained beyond the reach of traditional methods. In the past decade, the emerging field of social psychophysics has developed new methods to address this challenge, with the potential to transfer psychophysical laws of social perception to the digital economy via avatars and social robots. At this exciting juncture, it is timely to review these new methodological developments. In this article, we introduce and review the foundational methodological developments of social psychophysics, present work done in the past decade that has advanced understanding of the face as a tool for social communication, and discuss the major challenges that lie ahead.

Pose-Invariant Face Recognition via RGB-D Images.

PubMed

Sang, Gaoli; Li, Jing; Zhao, Qijun

2016-01-01

Three-dimensional (3D) face models can intrinsically handle large pose face recognition problem. In this paper, we propose a novel pose-invariant face recognition method via RGB-D images. By employing depth, our method is able to handle self-occlusion and deformation, both of which are challenging problems in two-dimensional (2D) face recognition. Texture images in the gallery can be rendered to the same view as the probe via depth. Meanwhile, depth is also used for similarity measure via frontalization and symmetric filling. Finally, both texture and depth contribute to the final identity estimation. Experiments on Bosphorus, CurtinFaces, Eurecom, and Kiwi databases demonstrate that the additional depth information has improved the performance of face recognition with large pose variations and under even more challenging conditions.

Marie, Mohammad; Hannigan, Ben; Jones, Aled

2017-01-01

Nurses in Palestine (occupied Palestinian territory) work in a significantly challenging environment. The mental health care system is underdeveloped and under-resourced. For example, the total number of nurses who work in community mental health centres in the West Bank is seventeen, clearly insufficient in a total population of approximately three million. This research explored daily challenges that Palestinian community mental health nurses (CMHNs) face within and outside their demanding workplaces. An interpretive qualitative design was chosen. Face-to-face interviews were completed with fifteen participants. Thirty-two hours of observations of the day-to-day working environment and workplace routines were conducted in two communities' mental health centres. Written documents relating to practical job-related policies were also collected from various workplaces. Thematic analysis was used across all data sources resulting in four main themes, which describe the challenges faced by CMHNs. These themes consist of the context of unrest, stigma, lack of resources, and organisational or mental health system challenges. The study concludes with a better understanding of challenges in nursing which draws on wider cultural contexts and resilience. The outcomes from this study can be used to decrease the challenges for health professionals and enhance the mental health care system in Palestine.

The global land rush and climate change

NASA Astrophysics Data System (ADS)

Davis, Kyle Frankel; Rulli, Maria Cristina; D'Odorico, Paolo

2015-08-01

Climate change poses a serious global challenge in the face of rapidly increasing human demand for energy and food. A recent phenomenon in which climate change may play an important role is the acquisition of large tracts of land in the developing world by governments and corporations. In the target countries, where land is relatively inexpensive, the potential to increase crop yields is generally high and property rights are often poorly defined. By acquiring land, investors can realize large profits and countries can substantially alter the land and water resources under their control, thereby changing their outlook for meeting future demand. While the drivers, actors, and impacts involved with land deals have received substantial attention in the literature, we propose that climate change plays an important yet underappreciated role, both through its direct effects on agricultural production and through its influence on mitigative or adaptive policy decisions. Drawing from various literature sources as well as a new global database on reported land deals, we trace the evolution of the global land rush and highlight prominent examples in which the role of climate change is evident. We find that climate change—both historical and anticipated—interacts substantially with drivers of land acquisitions, having important implications for the resilience of communities in targeted areas. As a result of this synthesis, we ultimately contend that considerations of climate change should be integrated into future policy decisions relating to the large-scale land acquisitions.

Integration of conservation partnerships across geographic, biological, and administrative boundaries is increasingly relevant because drivers of change, such as climate shifts, transcend these boundaries. We explored successes and challenges of established conservation programs that span multiple watersheds and consider both social and ecological concerns. We asked representatives from a diverse set of 11 broad-extent conservation partnerships in 29 countries 17 questions that pertained to launching and maintaining partnerships for broad-extent conservation, specifying ultimate management objectives, and implementation and learning. Partnerships invested more funds in implementing conservation actions than any other aspect of conservation, and a program's context (geographic extent, United States vs. other countries, developed vs. developing nation) appeared to substantially affect program approach. Despite early successes of these organizations and benefits of broad-extent conservation, specific challenges related to uncertainties in scaling up information and to coordination in the face of diverse partner governance structures, conflicting objectives, and vast uncertainties regarding future system dynamics hindered long-term success, as demonstrated by the focal organizations. Engaging stakeholders, developing conservation measures, and implementing adaptive management were dominant challenges. To inform future research on broad-extent conservation, we considered several challenges when we developed detailed questions, such as what qualities of broad-extent partnerships ensure they complement, integrate, and strengthen, rather than replace, local conservation efforts and which adaptive management processes yield actionable conservation strategies that account explicitly for dynamics and uncertainties regarding multiscale governance, environmental conditions, and knowledge of the system? © 2014 Society for Conservation Biology.

To illustrate the current situation and problems of drug addiction in treatment China and propose suggestions. A descriptive study based on literature searched from Medline and the China National Knowledge Infrastructure database (1996-2007) and hand-picked references. Since the re-emergence of drug addiction in China in the early 1990s, there has been tremendous progress in drug addiction treatments in China, especially treatments for opiate addiction. However, many problems and challenges remain for improvement, including widespread negative attitudes towards drug abuse and drug-dependent individuals, the lack of evidence-based data on the efficacy of Chinese traditional medicine and the lack of a comprehensive and integrated system to organize all treatment resources and monitor treatment progress. The authors discuss the challenges that impede effective treatments of drug addiction and some suggestions are proposed. Implementing these suggestions can improve the outcome of treatment of drug-dependent individuals and benefit the whole society. China faces substantial drug addiction problems that appear to be worsening with time. Although much progress in drug addiction treatment has been made, improvement in many aspects is needed urgently.

Linking Environmental Research and Practice: Lessons From The Integration of Climate Science and Water Management in the Western United States

Efforts to better connect scientific research with people and organizations involved in environmental decision making are receiving increased interest and attention. Some of the challenges we currently face, however—including complex questions associated with climate change—present unique challenges because of their scale and scope. Focused research on the intersections between environment and society has provided substantial insight into dynamics of large-scale environmental change and the related impacts on people, natural resources, and ecosystems, yet our ability to connect this research to real-world decision making remains limited. Addressing these complex environmental problems requires broad cooperation between scientists and those who may apply research results in decision making, but there are few templates for guiding the growing number of scientists and practitioners now engaging in this kind of cooperative work. This presentation will offer a set of heuristics for carrying out collaborative work between scientists and practitioners. These heuristics were derived from research that examined the direct experiences of water resources professionals and climate researchers who have been working to integrate science and practice.

Polymeric micelles in mucosal drug delivery: Challenges towards clinical translation.

PubMed

Sosnik, Alejandro; Menaker Raskin, Maya

2015-11-01

Polymeric micelles are nanostructures formed by the self-aggregation of copolymeric amphiphiles above the critical micellar concentration. Due to the flexibility to tailor different molecular features, they have been exploited to encapsulate motley poorly-water soluble therapeutic agents. Moreover, the possibility to combine different amphiphiles in one single aggregate and produce mixed micelles that capitalize on the features of the different components substantially expands the therapeutic potential of these nanocarriers. Despite their proven versatility, polymeric micelles remain elusive to the market and only a few products are currently undergoing advanced clinical trials or reached clinical application, all of them for the therapy of different types of cancer and administration by the intravenous route. At the same time, they emerge as a nanotechnology platform with great potential for non-parenteral mucosal administration. However, for this, the interaction of polymeric micelles with mucus needs to be strengthened. The present review describes the different attempts to develop mucoadhesive polymeric micelles and discusses the challenges faced in the near future for a successful bench-to-bedside translation.

The purpose of this study was to explore challenges faced by patients with systemic sclerosis, also called scleroderma, in coping with their disease and the strategies they used to face those challenges. Five focus groups were held with scleroderma patients (4 groups, n = 34) and health care professionals who have experience treating scleroderma (1 group, n = 8). Participants' discussions were recorded, transcribed and analyzed using thematic analysis. Participants reported challenges accessing information (e.g., knowledgeable specialists), dealing with negative emotions (e.g., stress due to misunderstandings with loved ones), and accessing resources (e.g., helpful products or devices). Strategies for overcoming challenges were also discussed (e.g., advocating for own needs). When faced with significant challenges while coping with scleroderma, patients develop strategies to manage better and improve their quality of life. To help them cope, patients would benefit from easier access to supportive interventions, including tailored scleroderma self-management programs. Although the challenges experienced by patients with scleroderma are unique, findings from this study might help better understand patients' perspectives regarding coping and disease management for other chronic diseases as well. Implications for Rehabilitation People living with rare diseases, including the rare autoimmune disease scleroderma, face unique challenges and often do not have access to disease-specific educational or other support resources. People with scleroderma report that they face challenges in accessing information, including knowledgeable healthcare providers; managing difficult social interactions and negative emotions; and accessing resources. Strategies employed by scleroderma patients to overcome these challenges include seeking connections to other people with scleroderma or scleroderma patient organizations, actively seeking out local resources, and learning to communicate and advocate more effectively. Rehabilitation professionals can support people with scleroderma by providing them with information on connecting with scleroderma patient organizations or by facilitating local patient support networks.

People who leave their country of origin, or the country of habitual residence, to establish themselves permanently in another country are usually referred to as migrants. Over half of all births in Montreal, Canada are to migrant women. To understand healthcare professionals' attitudes towards migrants that could influence their delivery of care, our objective was to explore their perspectives of challenges newly-arrived migrant women from non-Western countries face when needing maternity care. In this qualitative multiple case study, we conducted face-to-face interviews with 63 health care professionals from four teaching hospitals in Montreal, known for providing maternity care to a high volume of migrant women. Interviews were transcribed and thematically analysed. Physicians, nurses, social workers, and therapists participated; 90% were female; and 17% were themselves migrants from non-Western countries. According to participants, newly-arrived migrant women face challenges at two levels: (a) direct care (e.g., understanding Canadian health care professionals' expectations, communicating effectively with health care professionals), and (b) organizational (e.g., access to appropriate health care). Challenges women face are strongly influenced by the migrant woman's background as well as social position (e.g., general education, health literacy, socio-cultural integration) and by how health care professionals balance women's needs with perceived requirement to adhere to standard procedures and regulations. Health care professionals across institutions agreed that maternity care-related challenges faced by newly-arrived migrant women often are complex in that they are simultaneously driven by conflicting values: those based on migrant women's sociocultural backgrounds versus those related to the implementation of Canadian guidelines for maternity care in which consideration of migrant women's particular needs are not priority.

Population genetic testing for cancer susceptibility: founder mutations to genomes.

PubMed

Foulkes, William D; Knoppers, Bartha Maria; Turnbull, Clare

2016-01-01

The current standard model for identifying carriers of high-risk mutations in cancer-susceptibility genes (CSGs) generally involves a process that is not amenable to population-based testing: access to genetic tests is typically regulated by health-care providers on the basis of a labour-intensive assessment of an individual's personal and family history of cancer, with face-to-face genetic counselling performed before mutation testing. Several studies have shown that application of these selection criteria results in a substantial proportion of mutation carriers being missed. Population-based genetic testing has been proposed as an alternative approach to determining cancer susceptibility, and aims for a more-comprehensive detection of mutation carriers. Herein, we review the existing data on population-based genetic testing, and consider some of the barriers, pitfalls, and challenges related to the possible expansion of this approach. We consider mechanisms by which population-based genetic testing for cancer susceptibility could be delivered, and suggest how such genetic testing might be integrated into existing and emerging health-care structures. The existing models of genetic testing (including issues relating to informed consent) will very likely require considerable alteration if the potential benefits of population-based genetic testing are to be fully realized.

The growth of herbal markets has increased substantially in South Korea, but the worldwide market share remains small despite significant governmental efforts. This study aimed to characterize manufacturing employment and identify employees' general perceptions of market expansion. A survey study covering 567 companies was conducted using face-to-face interviews in 2012. Data were analyzed using comparisons among three manufacturing groups (i.e., the herbal dietary supplement manufacturing group, the herbal medicine manufacturing group, and the personal care product manufacturing group) or among the manufacturers themselves. We found that the majority of the manufacturing employee respondents were regular permanent and production workers. The domestic distributors were primarily chain stores/direct outlets or retailers/wholesalers, and the dominant product was red ginseng (hongsam). Although the responding companies exhibited a variety of perspectives, “advertisement/public relations” was cited as the most important factor in the development of the herbal industry. In contrast, “low manpower/seeking business partners” were the most crucial limiting and challenging factors for market globalization. Our results can be used to design a proper national plan by reducing the gaps in perspective between herbal product producers and policy makers. PMID:26199635

Sponsorship: a path to the academic medicine C-suite for women faculty?

Travis, Elizabeth L; Doty, Leilani; Helitzer, Deborah L

2013-10-01

Despite increases in the percentages of women medical school graduates and faculty over the past decade, women physicians and scientists remain underrepresented in academic medicine's highest-level executive positions, known as the "C-suite." The challenges of today and the future require novel approaches and solutions that depend on having diverse leaders. Such diversity has been widely shown to be critical to creating initiatives and solving complex problems such as those facing academic medicine and science. However, neither formal mentoring programs focused on individual career development nor executive coaching programs focused on individual job performance have led to substantial increases in the proportion of women in academic medicine's top leadership positions.Faced with a similar dilemma, the corporate world has initiated sponsorship programs designed to accelerate the careers of women as leaders. Sponsors differ from mentors and coaches in one key area: They have the position and power to advocate publicly for the advancement of nascent talent, including women, in the organization. Although academic medicine differs from the corporate world, the strong sponsorship programs that have advanced women into corporations' upper levels of leadership can serve as models for sponsorship programs to launch new leaders in academic medicine.

2015-03-01

Recently, the healthcare sector has shown a growing interest in information technologies. Two popular health IT (HIT) products are the electronic health record (EHR) and health information exchange (HIE) networks. The introduction of these tools is believed to improve care, but has also raised some important questions and legal and privacy issues. The implementation of these systems has not gone smoothly, and still faces some considerable barriers. This article reviews EHR and HIE to address these obstacles, and analyzes the current state of development and adoption in various countries around the world. Moreover, legal and ethical concerns that may be encountered by EHR users and purchasers are reviewed. Finally, links and interrelations between EHR and HIE and several quality of care issues in today's healthcare domain are examined with a focus on EHR and HIE in the emergency department (ED), whose unique characteristics makes it an environment in which the implementation of such technology may be a major contributor to health, but also faces substantial challenges. The paper ends with a discussion of specific policy implications and recommendations based on an examination of the current limitations of these systems. Copyright © 2014 Elsevier Ireland Ltd.

Increased trade between China and Uganda has fueled trafficking of female Ugandans into China. These women may face challenges accessing health services. This study focused on examining barriers to health care access among female Ugandan sex workers in China. In 2014, we undertook in-depth interviews with 19 female Ugandan sex workers in Guangzhou, China. Interviews focused on barriers to health service access and were analyzed using an a priori coding framework followed by open-coding to capture emergent themes. Out of 19 women, 12 women reported a history of being trafficked into China. None of the women had a valid Chinese visa. Fear of being arrested for lack of documentation discouraged women in this sample from accessing hospital services. Low pay, housing exploitation, and remittances contributed to participants' lack of financial resources, which further inhibited their ability to access health services. Participants expressed feeling social isolation from the local community and reported mistrust of local individuals and organizations, including hospitals. Ugandan sex workers in China faced substantial structural barriers that limited health service access. Policy changes and the development of new programs are urgently needed to ensure these women have improved access to health services.

Protecting water and wastewater infrastructure from cyber attacks

NASA Astrophysics Data System (ADS)

Panguluri, Srinivas; Phillips, William; Cusimano, John

2011-12-01

Multiple organizations over the years have collected and analyzed data on cyber attacks and they all agree on one conclusion: cyber attacks are real and can cause significant damages. This paper presents some recent statistics on cyber attacks and resulting damages. Water and wastewater utilities must adopt countermeasures to prevent or minimize the damage in case of such attacks. Many unique challenges are faced by the water and wastewater industry while selecting and implementing security countermeasures; the key challenges are: 1) the increasing interconnection of their business and control system networks, 2) large variation of proprietary industrial control equipment utilized, 3) multitude of cross-sector cyber-security standards, and 4) the differences in the equipment vendor's approaches to meet these security standards. The utilities can meet these challenges by voluntarily selecting and adopting security standards, conducting a gap analysis, performing vulnerability/risk analysis, and undertaking countermeasures that best meets their security and organizational requirements. Utilities should optimally utilize their limited resources to prepare and implement necessary programs that are designed to increase cyber-security over the years. Implementing cyber security does not necessarily have to be expensive, substantial improvements can be accomplished through policy, procedure, training and awareness. Utilities can also get creative and allocate more funding through annual budgets and reduce dependence upon capital improvement programs to achieve improvements in cyber-security.

Projected response of an endangered marine turtle population to climate change

Assessing the potential impacts of climate change on individual species and populations is essential for the stewardship of ecosystems and biodiversity. Critically endangered leatherback turtles in the eastern Pacific Ocean are excellent candidates for such an assessment because their sensitivity to contemporary climate variability has been substantially studied. If incidental fisheries mortality is eliminated, this population still faces the challenge of recovery in a rapidly changing climate. Here we combined an Earth system model, climate model projections assessed by the Intergovernmental Panel on Climate Change and a population dynamics model to estimate a 7% per decade decline in the Costa Rica nesting population over the twenty-first century. Whereas changes in ocean conditions had a small effect on the population, the ~2.5°C warming of the nesting beach was the primary driver of the decline through reduced hatching success and hatchling emergence rate. Hatchling sex ratio did not substantially change. Adjusting nesting phenology or changing nesting sites may not entirely prevent the decline, but could offset the decline rate. However, if future observations show a long-term decline in hatching success and emergence rate, anthropogenic climate mitigation of nests (for example, shading, irrigation) may be able to preserve the nesting population.

STRUCTURAL AND CONNECTOMIC NEUROIMAGING FOR THE PERSONALIZED STUDY OF LONGITUDINAL ALTERATIONS IN CORTICAL SHAPE, THICKNESS AND CONNECTIVITY AFTER TRAUMATIC BRAIN INJURY

2014-01-01

The integration of longitudinal brain structure analysis with neurointensive care strategies continues to be a substantial difficulty facing the traumatic brain injury (TBI) research community. For patient-tailored case analysis, it remains challenging to establish how lesion profile modulates longitudinal changes in cortical structure and connectivity, as well as how these changes lead to behavioral, cognitive and neural dysfunction. Additionally, despite the clinical potential of morphometric and connectomic studies, few analytic tools are available for their study in TBI. Here we review the state of the art in structural and connectomic neuroimaging for the study of TBI and illustrate a set of recently-developed, patient-tailored approaches for the study of TBI-related brain atrophy and alterations in morphometry as well as inter-regional connectivity. The ability of such techniques to quantify how injury modulates longitudinal changes in cortical shape, structure and circuitry is highlighted. Quantitative approaches such as these can be used to assess and monitor the clinical condition and evolution of TBI victims, and can have substantial translational impact, especially when used in conjunction with measures of neuropsychological function.

Measuring environmental efficiency of agricultural water use: a Luenberger environmental indicator.

PubMed

Azad, Md A S; Ancev, Tihomir

2014-12-01

Irrigated agriculture creates substantial environmental pressures by withdrawing large quantities of water, leaving rivers and wetlands empty and unable to support the valuable ecosystems that depend on the water resource. The key challenge facing society is that of balancing water extractions for agricultural production and other uses with provision of appropriate environmental flow to maintain healthy rivers and wetlands. Measuring tradeoffs between economic gain of water use in agriculture and its environmental pressures can contribute to constructing policy instruments for improved water resource management. The aim of this paper is to develop a modelling framework to measure these tradeoffs. Using a new approach - Luenberger environmental indicator - the study derives environmental efficiency scores for various types of irrigation enterprises across seventeen natural resource management regions within the Murray-Darling Basin, Australia. Findings show that there is a substantial variation in environmental performance of irrigation enterprises across the regions. Some enterprises were found to be relatively environmentally efficient in some regions, but they were not efficient in others. The environmental efficiency scores could be used as a guideline for formulating regional policy and strategy to achieve sustainable water use in the agricultural sector.

2017-05-24

We describe the natural auditory environment of people with cochlear implants (CIs), how it changes across the life span, and how it varies between individuals. We performed a retrospective cross-sectional analysis of Cochlear Nucleus 6 CI sound-processor data logs. The logs were obtained from 1,501 people with CIs (ages 0-96 years). They covered over 2.4 million hr of implant use and indicated how much time the CI users had spent in various acoustical environments. We investigated exposure to spoken language, noise, music, and quiet, and analyzed variation between age groups, users, and countries. CI users spent a substantial part of their daily life in noisy environments. As a consequence, most speech was presented in background noise. We found significant differences between age groups for all auditory scenes. Yet even within the same age group and country, variability between individuals was substantial. Regardless of their age, people with CIs face challenging acoustical environments in their daily life. Our results underline the importance of supporting them with assistive listening technology. Moreover, we found large differences between individuals' auditory diets that might contribute to differences in rehabilitation outcomes. Their causes and effects should be investigated further.

Resnik, Linda J; Allen, Susan M

2007-01-01

This pilot study used the framework of the World Health Organization's International Classification of Functioning, Disability and Health (ICF) to understand the challenges faced by Operation Enduring Freedom (OEF) and Operation Iraqi Freedom (OIF) veterans as they reintegrate into the community. We conducted semistructured interviews with 14 injured veterans, 12 caregivers, and 14 clinicians. We used ICF taxonomy to code data and identify issues. We identified challenges in the following ICF domains: learning and applying knowledge; general tasks and demands; communication; mobility; self-care; domestic life; interpersonal interactions, major life areas; and community, social, and civic life. We found many similarities between the challenges faced by veterans with and without polytraumatic injuries, although veterans with polytraumatic injuries faced challenges of greater magnitude. Identifying community reintegration challenges early and promoting reintegration are important mandates for the Department of Veterans Affairs. The findings of this study are useful in understanding the needs of OEF/OIF veterans.

Ethical challenges facing veterinary professionals in Ireland: results from Policy Delphi with vignette methodology

Ethics is key to the integrity of the veterinary profession. Despite its importance, there is a lack of applied research on the range of ethical challenges faced by veterinarians. A three round Policy Delphi with vignette methodology was used to record the diversity of views on ethical challenges faced by veterinary professionals in Ireland. Forty experts, comprising veterinary practitioners, inspectors and nurses, accepted to participate. In round 1, twenty vignettes describing a variety of ethically challenging veterinary scenarios were ranked in terms of ethical acceptability, reputational risk and perceived standards of practice. Round 2 aimed at characterising challenges where future policy development or professional guidance was deemed to be needed. In round 3, possible solutions to key challenges were explored. Results suggest that current rules and regulations are insufficient to ensure best veterinary practices and that a collective approach is needed to harness workable solutions for the identified ethical challenges. Challenges pertaining mostly to the food chain seem to require enforcement measures whereas softer measures that promote professional discretion were preferred to address challenges dealing with veterinary clinical services. These findings can support veterinary representative bodies, advisory committees and regulatory authorities in their decision making, policy and regulation. PMID:27613779

Ethics is key to the integrity of the veterinary profession. Despite its importance, there is a lack of applied research on the range of ethical challenges faced by veterinarians. A three round Policy Delphi with vignette methodology was used to record the diversity of views on ethical challenges faced by veterinary professionals in Ireland. Forty experts, comprising veterinary practitioners, inspectors and nurses, accepted to participate. In round 1, twenty vignettes describing a variety of ethically challenging veterinary scenarios were ranked in terms of ethical acceptability, reputational risk and perceived standards of practice. Round 2 aimed at characterising challenges where future policy development or professional guidance was deemed to be needed. In round 3, possible solutions to key challenges were explored. Results suggest that current rules and regulations are insufficient to ensure best veterinary practices and that a collective approach is needed to harness workable solutions for the identified ethical challenges. Challenges pertaining mostly to the food chain seem to require enforcement measures whereas softer measures that promote professional discretion were preferred to address challenges dealing with veterinary clinical services. These findings can support veterinary representative bodies, advisory committees and regulatory authorities in their decision making, policy and regulation. British Veterinary Association.

We mark the 50th anniversary of the International Committee on Taxonomy of Viruses (ICTV) by presenting a brief history of the organization since its foundation, showing how it has adapted to advancements in our knowledge of virus diversity and the methods used to characterize it. We also outline recent developments, supported by a grant from the Wellcome Trust (UK), that are facilitating substantial changes in the operations of the ICTV and promoting dialogue with the virology community. These developments will generate improved online resources, including a freely available and regularly updated ICTV Virus Taxonomy Report. They also include a series of meetings between the ICTV and the broader community focused on some of the major challenges facing virus taxonomy, with the outcomes helping to inform the future policy and practice of the ICTV.

What does free cash flow tell us about hospital efficiency? A stochastic frontier analysis of cost inefficiency in California hospitals.

PubMed

Pratt, William R

2010-01-01

Hospitals are facing substantial financial and economic pressure as a result of health plan payment restructuring, unfunded mandates, and other factors. This article analyzes the relationship between free cash flow (FCF) and hospital efficiency given these financial challenges. Data from 270 California hospitals were used to estimate a stochastic frontier model of hospital cost efficiency that explicitly takes into account outpatient heterogeneity. The findings indicate that hospital FCF is significantly linked to firm efficiency/inefficiency. The results indicate that higher positive cash flows are related to lower cost inefficiency, but higher negative cash flows are related to higher cost inefficiency. Thus, cash flows not only impact the ability of hospitals to meet current liabilities, they are also related to the ability of the hospitals to use resources effectively.

Vascularization remains one of the most important challenges that must be overcome for tissue engineering to be consistently implemented for reconstruction of large volume bone defects. An extensive vascular network is needed for transport of nutrients, waste and progenitor cells required for remodelling and repair. A variety of tissue engineering strategies have been investigated in an attempt to vascularize tissues, including those applying cells, soluble factor delivery strategies, novel design and optimization of bio-active materials, vascular assembly pre-implantation and surgical techniques. However, many of these strategies face substantial barriers that must be overcome prior to their ultimate translation into clinical application. In this review recent progress in engineering vascularized bone will be presented with an emphasis on clinical feasibility. © 2015 The Authors.

Preventing ARDS

PubMed Central

Beitler, Jeremy R.; Schoenfeld, David A.

2014-01-01

Advances in critical care practice have led to a substantial decline in the incidence of ARDS over the past several years. Low tidal volume ventilation, timely resuscitation and antimicrobial administration, restrictive transfusion practices, and primary prevention of aspiration and nosocomial pneumonia have likely contributed to this reduction. Despite decades of research, there is no proven pharmacologic treatment of ARDS, and mortality from ARDS remains high. Consequently, recent initiatives have broadened the scope of lung injury research to include targeted prevention of ARDS. Prediction scores have been developed to identify patients at risk for ARDS, and clinical trials testing aspirin and inhaled budesonide/formoterol for ARDS prevention are ongoing. Future trials aimed at preventing ARDS face several key challenges. ARDS has not been validated as an end point for pivotal clinical trials, and caution is needed when testing toxic therapies that may prevent ARDS yet potentially increase mortality. PMID:25288000

Structured models of infectious disease: inference with discrete data

Metcalf, C.J.E.; Lessler, J.; Klepac, P.; Morice, A.; Grenfell, B.T.; Bjørnstad, O.N.

2014-01-01

The usage of structured population models can make substantial contributions to public health, particularly for infections where clinical outcomes vary over age. There are three theoretical challenges in implementing such analyses: i) developing an appropriate framework that models both demographic and epidemiological transitions; ii) parameterizing the framework, where parameters may be based on data ranging from the biological course of infection, basic patterns of human demography, specific characteristics of population growth, and details of vaccination regimes implemented; and iii) evaluating public health strategies in the face of changing human demography. We illustrate the general approach by developing a model of rubella in Costa Rica. The demographic profile of this infection is a crucial aspect of its public health impact, and we use a transient perturbation analysis to explore the impact of changing human demography on immunization strategies implemented.

An optical panel 10 includes a plurality of waveguides 12 stacked together, with each waveguide 12 having a first end 12a and an opposite second end 12b. The first ends 12a collectively define a first face 16, and the second ends 12b collectively define a second face 18 of the panel 10. The second face 18 is disposed at an acute face angle relative to the waveguides 12 to provide a panel 10 which is relatively thin compared to the height of the second face. In an exemplary embodiment for use in a projection TV, the first face 16 is substantially smaller in height than the second face 18 and receives a TV image, with the second face 18 defining a screen for viewing the image enlarged.

Exploring strategies to overcome extra-organisational challenges faced by community pharmacies in Sarawak, Malaysia.

2018-03-15

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.

Athletes with Implantable Cardioverter Defibrillators

Ponamgi, Shiva P.; DeSimone, Christopher V.; Ackerman, Michael J.

2015-01-01

Summary Athletes with an implantable cardioverter defibrillator (ICD) represent a diverse group of individuals who may be at an increased risk of sudden cardiac death (SCD) when engaging in vigorous physical activity. Therefore, they are excluded by the current guidelines from participating in most competitive sports except those classified as low intensity, such as bowling and golf. The lack of substantial data on the natural history of the cardiac diseases affecting these athletes, as well as the unknown efficacy of implanted ICDs in terminating life-threatening arrhythmias occurring during intense exercise, have resulted in the restrictive nature of these now decade old guidelines. Recently, there is emerging data, derived from a few retrospective studies and a large prospective registry that demonstrates the relative safety of high-risk athletes participating in competitive sports and challenges the prohibitive nature of these guidelines. Nevertheless, the safe participation of all athletes with an ICD in competitive sports continues to be contemplated. The increased number of inappropriate shocks, damage to the ICD/pacemaker system, and the questionable efficacy of the delivered shock in the setting of vigorous physical activity are some of the main challenges faced by these athletes who choose to continue participation in competitive sports. The fear of SCD and ICD shocks faced by these athletes is also associated with a negative psychological burden and affects their quality of life, as does restricting them from all competitive sports. Therefore, shared decision making is necessary between the clinician and athlete after carefully analyzing the risks and benefits associated with competitive sports participation. PMID:26100423

Missed Opportunities for Science Learning: Unacknowledged Unscientific Arguments in Asynchronous Online and Face-to-Face Discussions

Callis-Duehl, Kristine; Idsardi, Robert; Humphrey, Eve A.; Gougis, Rebekka Darner

2018-02-01

We explored the scientific argumentation that occurs among university biology students during an argumentation task implemented in two environments: face-to-face in a classroom and online in an asynchronous discussion. We observed 10 student groups, each composed of three students. Our analysis focused on how students respond to their peers' unscientific arguments, which we define as assertions, hypotheses, propositions, or explanations that are inaccurate or incomplete from a scientific perspective. Unscientific arguments provide opportunities for productive dissent, scientific argumentation, and conceptual development of scientifically desirable conceptions. We found that students did not respond to the majority of unscientific arguments in both environments. Challenges to unscientific arguments were expressed as a question or through explanation, although the latter was more common online than face-to-face. Students demonstrated significantly more epistemic distancing in the face-to-face environment than the online environment. We discuss the differences in discourse observed in both environments and teaching implications. We also provide direction for future research seeking to address the challenges of engaging students in productive scientific argumentation in both face-to-face and online environments.

The other-race effect does not rely on memory: Evidence from a matching task.

PubMed

Megreya, Ahmed M; White, David; Burton, A Mike

2011-08-01

Viewers are typically better at remembering faces from their own race than from other races; however, it is not yet established whether this effect is due to memorial or perceptual processes. In this study, UK and Egyptian viewers were given a simultaneous face-matching task, in which the target faces were presented upright or upside down. As with previous research using face memory tasks, participants were worse at matching other-race faces than own-race faces and showed a stronger face inversion effect for own-race faces. However, subjects' performance on own and other-race faces was highly correlated. These data provide strong evidence that difficulty in perceptual encoding of unfamiliar faces contributes substantially to the other-race effect and that accounts based entirely on memory cannot capture the full data. Implications for forensic settings are also discussed.

2016-10-01

Female physicians may experience unique challenges regarding fertility and family planning. We sought to determine childbearing patterns and decision-making among American female physicians. In 2012-2013, we surveyed a random sample of 600 female physicians who graduated medical school between 1995 and 2000. Primary outcome measures included fertility and childbearing history, reflections regarding decision-making, perceptions of workplace support, and estimations of childbearing potential. Response rate was 54.5% (327/600). A majority (82.0%) of the sample were parents, 77.4% had biological children with an average of 2.3 children. Average age at medical school graduation was 27.5 years, at completion of training (completion of medical school, residency, and/or fellowship) was 31.6 years, and at first pregnancy was 30.4 years. Nearly one quarter (24.1%) of respondents who had attempted conception were diagnosed with infertility, with an average age at diagnosis of 33.7 years. Among those with infertility, 29.3% reported diminished ovarian reserve. When asked what they would do differently in retrospect, most respondents (56.8%) would do nothing differently regarding fertility/conception/childbearing, 28.6% would have attempted conception earlier, 17.1% would have gone into a different specialty, and 7.0% would have used cryopreservation to extend fertility. Fewer of those whose first pregnancy was in medical school perceived substantial workplace support (68.2%) than those whose first pregnancies followed training (88.6%). A substantial proportion of female physicians have faced infertility or have regrets about family planning decisions and career decision-making. Combining a medical career with motherhood continues to pose challenges, meriting further investigation and targeted support.

Common genetic risk factors for coronary artery disease: new opportunities for prevention?

PubMed

Hamrefors, Viktor

2017-05-01

Atherosclerotic cardiovascular disease (CVD) is a leading cause of mortality and morbidity worldwide, with coronary artery disease (CAD) being the single leading cause of death. Better control of risk factors, enhanced diagnostic techniques and improved medical therapies have all substantially decreased the mortality of CAD in developed countries. However, CAD and other forms of atherosclerotic CVD are projected to remain the leading cause of death by 2030 and we face a number of challenges if the outcomes of CAD are to be further improved. The fact that a substantial fraction of high-risk subjects do not reach treatment goals for important risk factors is one of these challenges. At the same time, there is also a non-negotiable fraction of 'concealed' high-risk subjects who are not detected by current risk algorithms and diagnostic modalities. In recent years, we have started to rapidly increase our knowledge of the framework of common genetics underlying CAD and atherosclerotic CVD in the population. In conjunction with modern diagnostic and therapeutic options, this new genetic knowledge may provide a valuable tool for further improvements in prevention. This review summarizes the recent findings from the search for common genetic risk factors for CAD. Furthermore, the author discusses how such recent findings could potentially be used in a number of clinical applications within CAD prevention, including in clinical risk stratification, in prediction of drug treatment response and in the search for targets for novel preventive therapies. © 2015 Scandinavian Society of Clinical Physiology and Nuclear Medicine.

Trends in disability and program participation among U.S. veterans.

PubMed

Ben-Shalom, Yonatan; Tennant, Jennifer R; Stapleton, David C

2016-07-01

Disability is increasingly part of the lives of veterans and more research is needed to understand its impact on veterans' participation in disability benefit programs. We examine how recent trends in receipt of service-connected disability compensation from the Department of Veterans Affairs (VA) compare to trends in self-reported disability and participation in Social Security Disability Insurance (DI) and Supplemental Security Income (SSI) among veterans. We use 2002-2013 data from the Current Population Survey to describe trends in receipt of VA disability compensation and to compare between trends in self-reported disability and DI/SSI participation for veterans versus nonveterans. The percentage of veterans reporting they receive VA disability compensation increased substantially from 2002 to 2013 and was especially notable among younger (ages 18-39) and older (ages 50-64) veterans. From 2009 to 2013, self-reported disability increased among the younger and older veterans but not among middle-age veterans and nonveterans, and self-reported cognitive disability increased substantially among young veterans. DI/SSI participation among older veterans increased more than for nonveterans over the period examined. Effective policies are needed to incentivize work among young veterans and to help them obtain both the skills they need to succeed in the labor force and the supports (such as psychiatric health services) they need to do so. Older veterans are facing increasing challenges in the labor market, and further research is needed to determine whether these challenges are primarily related to health, a growing skills gap, or poorly-aligned incentives.

2006-05-01

To determine the etiologic factors, circumstances of diagnosis, obstetrical management and complications of face presentation and to value the maternal and foetal prognosis of this presentation. Thirty-two cases of face presentation have been observed in the maternity wards of Reims and Troyes over the last 12 years. The incidence of face presentation was 0.7 per 1000 deliveries. Spontaneous vaginal delivery occurred with mento-anterior presentation 73% of the time and caesarean section was performed in 100% of mento-posterior presentation. There was no increasing rate of foetal or maternal mortality and morbidity with vaginal delivery. Face presentation is an unusual complication of pregnancy with obstetric factors that predispose the foetus to face presentation. The low foetal and maternal mortality and morbidity substantiate the effectiveness of conservative management in face presentation.

Face adaptation improves gender discrimination.

PubMed

Yang, Hua; Shen, Jianhong; Chen, Juan; Fang, Fang

2011-01-01

Adaptation to a visual pattern can alter the sensitivities of neuronal populations encoding the pattern. However, the functional roles of adaptation, especially in high-level vision, are still equivocal. In the present study, we performed three experiments to investigate if face gender adaptation could affect gender discrimination. Experiments 1 and 2 revealed that adapting to a male/female face could selectively enhance discrimination for male/female faces. Experiment 3 showed that the discrimination enhancement induced by face adaptation could transfer across a substantial change in three-dimensional face viewpoint. These results provide further evidence suggesting that, similar to low-level vision, adaptation in high-level vision could calibrate the visual system to current inputs of complex shapes (i.e. face) and improve discrimination at the adapted characteristic.

Challenges in healthcare delivery in an economic downturn, in the Republic of Ireland.

PubMed

Carney, Marie

2010-07-01

The purpose of the present study was to discuss some of effects of the downturn in the Irish economy and to demonstrate that in the face of economic difficulties innovation in health care is still occurring. Staff that are managing and delivering healthcare need to know the challenges facing them and have an awareness of the importance of maintaining interest in innovative practice in turbulent times. Information obtained from several sources including government papers, the nursing regulatory board and quality authority documents and current best practice articles. Information was evaluated based on the study's aim. Issues emerging were that current challenges facing Irish health care delivery relate mainly to economic, clinical management, education and information technology factors and further reductions in the cost base of health care delivery remains focused on value for money. In the face of the economic downturn Ireland is achieving health targets and is now sitting in 13th place on the European health index, down from number 28 in 2008. This improvement in position has resulted from several new innovative work practices. As a result of cost reduction measures in place nurse managers will face greater challenges than ever before in meeting the objectives of the healthcare transformation programme.

A new entity for the negotiation of public procurement prices for patented medicines in Mexico.

PubMed

Gómez-Dantés, Octavio; Wirtz, Veronika J; Reich, Michael R; Terrazas, Paulina; Ortiz, Maki

2012-10-01

As countries expand health insurance coverage, their expenditures on medicines increase. To address this problem, WHO has recommended that every country draw up a list of essential medicines. Although most medicines on the list are generics, in many countries patented medicines represent a substantial portion of pharmaceutical expenditure. To help control expenditure on patented medicines, in 2008 the Mexican Government created the Coordinating Commission for Negotiating the Price of Medicines and other Health Inputs (CCPNM), whose role, as the name suggests, is to enter into price negotiations with drug manufacturers for patented drugs on Mexico's list of essential medicines. Mexico's public expenditure on pharmaceuticals has increased substantially in the past decade owing to government efforts to achieve universal health-care coverage through Seguro Popular, an insurance programme introduced in 2004 that guarantees access to a comprehensive package of health services and medicines. Since 2008, the CCPNM has improved procurement practices in Mexico's public health institutions and has achieved significant price reductions resulting in substantial savings in public pharmaceutical expenditure. The CCPNM has successfully changed the landscape of price negotiation for patented medicines in Mexico. However, it is also facing challenges, including a lack of explicit indicators to assess CCPNM performance; a shortage of permanent staff with sufficient technical expertise; poor coordination among institutions in preparing background materials for the annual negotiation process in a timely manner; insufficient communication among committees and institutions; and a lack of political support to ensure the sustainability of the CCPNM.

A snapshot of health information exchange across five nations: an investigation of frontline clinician experiences in emergency care.

PubMed

Klapman, Seth; Sher, Emily; Adler-Milstein, Julia

2018-06-01

Ensuring the ability to exchange patient information among disparate electronic health records systems is a top priority and a domain of substantial public investment across countries. However, we know little about the extent to which current capabilities meet the needs of frontline clinicians. We conducted in-person, semistructured interviews with emergency care physicians and nurses in select hospitals in Canada, Denmark, Finland, Germany, and the USA. We characterized the state of health information exchange (HIE) by country and used thematic analysis to identify the perceived benefits of access to complete past medical history (PMH), the conditions under which PMH is sought, and the challenges to accessing and using HIE capabilities. HIE approaches, and the information electronically accessible to clinicians, differed by country. Benefits of access to PMH included safer care, reduced patient length of stay, and fewer lab and imaging orders. Conditions under which PMH was sought included moderate-acuity patients, patients with chronic conditions, and instances where accessing PMH was convenient. Challenges to HIE access and use included difficulty knowing where information is located, delay in receiving information, and difficulty finding information within documents. Even with different HIE approaches across countries, all clinicians reported shortcomings in their country's approach. Notably, challenges were similar and shaped the conditions under which PMH was sought. As countries continue to pursue broad-based HIE, they appear to be facing similar challenges in realizing HIE value and therefore have an opportunity to learn from one another.

Thermal-to-visible face recognition using partial least squares.

PubMed

Hu, Shuowen; Choi, Jonghyun; Chan, Alex L; Schwartz, William Robson

2015-03-01

Although visible face recognition has been an active area of research for several decades, cross-modal face recognition has only been explored by the biometrics community relatively recently. Thermal-to-visible face recognition is one of the most difficult cross-modal face recognition challenges, because of the difference in phenomenology between the thermal and visible imaging modalities. We address the cross-modal recognition problem using a partial least squares (PLS) regression-based approach consisting of preprocessing, feature extraction, and PLS model building. The preprocessing and feature extraction stages are designed to reduce the modality gap between the thermal and visible facial signatures, and facilitate the subsequent one-vs-all PLS-based model building. We incorporate multi-modal information into the PLS model building stage to enhance cross-modal recognition. The performance of the proposed recognition algorithm is evaluated on three challenging datasets containing visible and thermal imagery acquired under different experimental scenarios: time-lapse, physical tasks, mental tasks, and subject-to-camera range. These scenarios represent difficult challenges relevant to real-world applications. We demonstrate that the proposed method performs robustly for the examined scenarios.

Developing high-quality scientific research will be most effective if research communities with diverse skills and interests are able to share information and knowledge, are aware of the major challenges across disciplines, and can exploit economies of scale to provide robust answers and better inform policy. We evaluate opportunities and challenges facing the development of a more interactive research environment by developing an interdisciplinary synthesis of research on a single geographic region. We focus on the Amazon as it is of enormous regional and global environmental importance and faces a highly uncertain future. To take stock of existing knowledge and provide a framework for analysis we present a set of mini-reviews from fourteen different areas of research, encompassing taxonomy, biodiversity, biogeography, vegetation dynamics, landscape ecology, earth-atmosphere interactions, ecosystem processes, fire, deforestation dynamics, hydrology, hunting, conservation planning, livelihoods, and payments for ecosystem services. Each review highlights the current state of knowledge and identifies research priorities, including major challenges and opportunities. We show that while substantial progress is being made across many areas of scientific research, our understanding of specific issues is often dependent on knowledge from other disciplines. Accelerating the acquisition of reliable and contextualized knowledge about the fate of complex pristine and modified ecosystems is partly dependent on our ability to exploit economies of scale in shared resources and technical expertise, recognise and make explicit interconnections and feedbacks among sub-disciplines, increase the temporal and spatial scale of existing studies, and improve the dissemination of scientific findings to policy makers and society at large. Enhancing interaction among research efforts is vital if we are to make the most of limited funds and overcome the challenges posed by addressing large-scale interdisciplinary questions. Bringing together a diverse scientific community with a single geographic focus can help increase awareness of research questions both within and among disciplines, and reveal the opportunities that may exist for advancing acquisition of reliable knowledge. This approach could be useful for a variety of globally important scientific questions. © 2010 The Authors. Biological Reviews © 2010 Cambridge Philosophical Society.

Threats to family planning services in Michigan: organizational responses to economic and political challenges.

PubMed

Dalton, Vanessa K; Jacobson, Peter D; Berson-Grand, Julie; Weisman, Carol S

2005-01-01

Title X is the only federal funding specifically for contraception and family planning services. This study identifies the threats and challenges Title X family planning organizations face in Michigan, and examines organizational responses to these challenges. We hypothesized that organizational responses to current challenges, including recent legislation, would differ between organizational types. We used a multiple case study design to examine safety net providers that received Title X funding in 2001. Cases were selected to represent economic and geographic diversity and included a mix of population densities. Key informants at each organization participated in face-to-face, semistructured interviews. Interviews collected data on current challenges, organizational planning processes, and organizational responses. All Title X organizations reported significant challenges, including rising costs, increasing need, and inadequate funding. Private organizations were more concerned about political challenges, especially recent Michigan legislation, than health departments. Organizational type was associated with the type of response. Health departments tended to close clinics or cut services, whereas private organizations recruited insured populations and increased patient fees. Based on these findings, the family planning safety net in Michigan appears to be undergoing significant change. These changes may decrease the availability of affordable family planning services in Michigan.

PubMed Central

2001-01-01

Background The study is designed to assess the organisational and human resource challenges faced by Primary Care Trusts (PCTs). Its objectives are to: specify the organisational and human resources challenges faced by PCTs in fulfilling the roles envisaged in government and local policy; examine how PCTs are addressing these challenges, in particular, to describe the organisational forms they have adopted, and the OD/HR strategies and initiatives they have planned or in place; assess how effective these structures, strategies and initiatives have been in enabling the PCTs to meet the organisational and human resources challenges they face; identify the factors, both internal to the PCT and in the wider health community, which have contributed to the success or failure of different structures, strategies and initiatives. Methods The study will be undertaken in three stages. In Stage 1 the key literature on public sector and NHS organisational development and human resources management will be reviewed, and discussions will be held with key researchers and policy makers working in this area. Stage 2 will focus on detailed case studies in six PCTs designed to examine the organisational and human resources challenges they face. Data will be collected using semi-structured interviews, group discussion, site visits, observation of key meetings and examination of local documentation. The findings from the case study PCTs will be cross checked with a Reference Group of up to 20 other PCG/Ts, and key officers working in organisational development or primary care at local, regional and national level. In Stage 3 analysis of findings from the preparatory work, the case studies and the feedback from the Reference Group will be used to identify practical lessons for PCTs, key messages for policy makers, and contributions to further theoretical development.

2017-06-01

Parents play an important role in the successful implementation of AAC. Previous research has indicated that parents in different countries have varying perceptions about the use of AAC and face different challenges in its implementation. To date, there is limited information about the use of AAC by children in Malaysia or parents' views about its use. The aim of this study was to explore Malaysian parents' perception of AAC and their experience when supporting their children who use AAC. For this study, 12 parents of children with autism spectrum disorder and cerebral palsy were involved in semi-structured individual interviews. Qualitative content analysis was used to analyze interview data. Following analysis, three themes were identified: (a) impact of the use of AAC, (b) challenges faced, and (c) hopes and expectations. Participants reported that the use of AAC had a positive impact on their children, but that they faced challenges related to the child, the settings, and the system itself, as well as a lack of time and support. Findings from this study provide an insight for Malaysian speech therapists about the challenges faced by parents when supporting their children who use AAC, and how important it is to overcome these challenges to ensure successful implementation of AAC.

Future supply chains enabled by continuous processing--opportunities and challenges. May 20-21, 2014 Continuous Manufacturing Symposium.

PubMed

Srai, Jagjit Singh; Badman, Clive; Krumme, Markus; Futran, Mauricio; Johnston, Craig

2015-03-01

This paper examines the opportunities and challenges facing the pharmaceutical industry in moving to a primarily "continuous processing"-based supply chain. The current predominantly "large batch" and centralized manufacturing system designed for the "blockbuster" drug has driven a slow-paced, inventory heavy operating model that is increasingly regarded as inflexible and unsustainable. Indeed, new markets and the rapidly evolving technology landscape will drive more product variety, shorter product life-cycles, and smaller drug volumes, which will exacerbate an already unsustainable economic model. Future supply chains will be required to enhance affordability and availability for patients and healthcare providers alike despite the increased product complexity. In this more challenging supply scenario, we examine the potential for a more pull driven, near real-time demand-based supply chain, utilizing continuous processing where appropriate as a key element of a more "flow-through" operating model. In this discussion paper on future supply chain models underpinned by developments in the continuous manufacture of pharmaceuticals, we have set out; The significant opportunities to moving to a supply chain flow-through operating model, with substantial opportunities in inventory reduction, lead-time to patient, and radically different product assurance/stability regimes. Scenarios for decentralized production models producing a greater variety of products with enhanced volume flexibility. Production, supply, and value chain footprints that are radically different from today's monolithic and centralized batch manufacturing operations. Clinical trial and drug product development cost savings that support more rapid scale-up and market entry models with early involvement of SC designers within New Product Development. The major supply chain and industrial transformational challenges that need to be addressed. The paper recognizes that although current batch operational performance in pharma is far from optimal and not necessarily an appropriate end-state benchmark for batch technology, the adoption of continuous supply chain operating models underpinned by continuous production processing, as full or hybrid solutions in selected product supply chains, can support industry transformations to deliver right-first-time quality at substantially lower inventory profiles. © 2015 Wiley Periodicals, Inc. and the American Pharmacists Association.

Mental Disorder-The Need for an Accurate Definition.

PubMed

Telles-Correia, Diogo; Saraiva, Sérgio; Gonçalves, Jorge

2018-01-01

There are several reasons why a definition for mental disorder is essential. Among these are not only reasons linked to psychiatry itself as a science (nosology, research) but also to ethical, legal, and financial issues. The first formal definition of mental disorder resulted from a deep conceptual analysis led by Robert Spitzer. It emerged to address several challenges that psychiatry faced at the time, namely to serve as the starting point for an atheoretical and evidence-based classification of mental disorders, to justify the removal of homosexuality from classifications, and to counter the arguments of antipsychiatry. This definition has been updated, with some conceptual changes that make it depart from the main assumptions of Spitzer's original definition. In this article, we intend to review the factors that substantiated the emergence of the first formal definition of mental disorder that based all its later versions.

Phylogenetic divergence of cell biological features

PubMed Central

2018-01-01

Most cellular features have a range of states, but understanding the mechanisms responsible for interspecific divergence is a challenge for evolutionary cell biology. Models are developed for the distribution of mean phenotypes likely to evolve under the joint forces of mutation and genetic drift in the face of constant selection pressures. Mean phenotypes will deviate from optimal states to a degree depending on the effective population size, potentially leading to substantial divergence in the absence of diversifying selection. The steady-state distribution for the mean can even be bimodal, with one domain being largely driven by selection and the other by mutation pressure, leading to the illusion of phenotypic shifts being induced by movement among alternative adaptive domains. These results raise questions as to whether lineage-specific selective pressures are necessary to account for interspecific divergence, providing a possible platform for the establishment of null models for the evolution of cell-biological traits.

Recent Work on the Nature and Development of Delusions

PubMed Central

Miyazono, Kengo

2015-01-01

Abstract In this paper we review two debates in the current literature on clinical delusions. One debate is about what delusions are. If delusions are beliefs, why are they described as failing to play the causal roles that characterise beliefs, such as being responsive to evidence and guiding action? The other debate is about how delusions develop. What processes lead people to form delusions and maintain them in the face of challenges and counter‐evidence? Do the formation and maintenance of delusions require abnormal experience alone, or also reasoning biases or deficits? We hope to show that the focus on delusions has made a substantial contribution to the philosophy of the mind and continues to raise issues that are central to defining the concept of belief and gaining a better understanding of how people process information and learn about the world.

Yu, Xiaowen; Cheng, Huhu; Zhang, Miao; Zhao, Yang; Qu, Liangti; Shi, Gaoquan

2017-09-01

The high specific surface area and the excellent mechanical, electrical, optical and thermal properties of graphene make it an attractive component for high-performance stimuli-responsive or 'smart' materials. Complementary to these inherent properties, functionalization or hybridization can substantially improve the performance of these materials. Typical graphene-based smart materials include mechanically exfoliated perfect graphene, chemical vapour deposited high-quality graphene, chemically modified graphene (for example, graphene oxide and reduced graphene oxide) and their macroscopic assemblies or composites. These materials are sensitive to a range of stimuli, including gas molecules or biomolecules, pH value, mechanical strain, electrical field, and thermal or optical excitation. In this Review, we outline different graphene-based smart materials and their potential applications in actuators, chemical or strain sensors, self-healing materials, photothermal therapy and controlled drug delivery. We also introduce the working mechanisms of graphene-based smart materials and discuss the challenges facing the realization of their practical applications.

Value congruence in health care priority setting: social values, institutions and decisions in three countries.

PubMed

Landwehr, Claudia; Klinnert, Dorothea

2015-04-01

Most developed democracies have faced the challenge of priority setting in health care by setting up specialized agencies to take decisions on which medical services to include in public health baskets. Under the influence of Daniels and Sabin's seminal work on the topic, agencies increasingly aim to fulfil criteria of procedural justice, such as accountability and transparency. We assume, however, that the institutional design of agencies also and necessarily reflects substantial value judgments on the respective weight of distributive principles such as efficiency, need and equality. The public acceptance of prioritization decisions, and eventually of the health care system at large, will ultimately depend not only on considerations of procedural fairness, but also on the congruence between a society's values and its institutions. We study social values, institutions and decisions in three countries (France, Germany and the United Kingdom) in order to assess such congruence and formulate expectations on its effects.

Mesenchymal stem cells for bone repair and metabolic bone diseases.

Undale, Anita H; Westendorf, Jennifer J; Yaszemski, Michael J; Khosla, Sundeep

2009-10-01

Human mesenchymal stem cells offer a potential alternative to embryonic stem cells in clinical applications. The ability of these cells to self-renew and differentiate into multiple tissues, including bone, cartilage, fat, and other tissues of mesenchymal origin, makes them an attractive candidate for clinical applications. Patients who experience fracture nonunion and metabolic bone diseases, such as osteogenesis imperfecta and hypophosphatasia, have benefited from human mesenchymal stem cell therapy. Because of their ability to modulate immune responses, allogeneic transplant of these cells may be feasible without a substantial risk of immune rejection. The field of regenerative medicine is still facing considerable challenges; however, with the progress achieved thus far, the promise of stem cell therapy as a viable option for fracture nonunion and metabolic bone diseases is closer to reality. In this review, we update the biology and clinical applicability of human mesenchymal stem cells for bone repair and metabolic bone diseases.

Major design issues of molten carbonate fuel cell power generation unit

In addition to the stack, a fuel cell power generation unit requires fuel desulfurization and reforming, fuel and oxidant preheating, process heat removal, waste heat recovery, steam generation, oxidant supply, power conditioning, water supply and treatment, purge gas supply, instrument air supply, and system control. These support facilities add considerable cost and system complexity. Bechtel, as a system integrator of M-C Power`s molten carbonate fuel cell development team, has spent substantial effort to simplify and minimize these supporting facilities to meet cost and reliability goals for commercialization. Similiar to other fuels cells, MCFC faces design challenge of how to complymore » with codes and standards, achieve high efficiency and part load performance, and meanwhile minimize utility requirements, weight, plot area, and cost. However, MCFC has several unique design issues due to its high operating temperature, use of molten electrolyte, and the requirement of CO2 recycle.« less

Male circumcision and HIV infection risk.

Krieger, John N

2012-02-01

Male circumcision is being promoted to reduce human immunodeficiency virus type 1 (HIV) infection rates. This review evaluates the scientific evidence suggesting that male circumcision reduces HIV infection risk in high-risk heterosexual populations. We followed the updated International Consultation on Urological Diseases evidence-based medicine recommendations to critically review the scientific evidence on male circumcision and HIV infection risk. Level 1 evidence supports the concept that male circumcision substantially reduces the risk of HIV infection. Three major lines of evidence support this conclusion: biological data suggesting that this concept is plausible, data from observational studies supported by high-quality meta-analyses, and three randomized clinical trials supported by high-quality meta-analyses. The evidence from these biological studies, observational studies, randomized controlled clinical trials, meta-analyses, and cost-effectiveness studies is conclusive. The challenges to implementation of male circumcision as a public health measure in high-risk populations must now be faced.

India's growing clinical research sector: opportunity for global companies.

2007-06-01

Backed by a compelling foundation of essential requirements necessary for effective clinical trial conduct, and aided by initiatives that address concerns of data quality, regulatory timelines and IP protection, the clinical development sector in India has experienced annual revenue growth rates of 25% in the past two to three years, and is poised to participate substantially in global drug development. As both clinical trial sponsors and CROs increase their research capabilities in India, the clinical development sector is facing challenges with staff resourcing and facilities. Existing initiatives in the clinical sector must continue, and further investment must be made by stakeholders to overcome the current limitations in sector growth. Furthermore, global organizations seeking to derive long-term sustainable revenue growth and competitive advantage in the global marketplace from their business units in India must establish an appropriate organizational culture and an effective intra-organizational and industry interface for their operations.

2017-06-01

Young adults with acute lymphoblastic leukemia are a distinctive category of patients, with substantial difference in disease biology and response to therapy; hence, they pose unique challenges and issues beyond those faced by children and older adults. Despite inferior survival compared to children, there is growing evidence to suggest that young adults have improved outcomes when treated with pediatric-based approaches. With better supportive care and toxicity management and multidisciplinary team and approach, we have made great improvement in outcomes of young adults with ALL. However, despite significant progress, patients with persistence of minimal residual disease have a poor prognosis. This review discusses current controversies in the management of young adults with ALL, outcomes following pediatric and adult protocols, and the role of allogeneic stem cell transplantation. We also explore recent advances in disease monitoring and highlight our approach to incorporation of novel therapies in the management of young adults with ALL.

Digital technologies will become a major part of our healthcare system, with particular impact in primary care. However, many healthcare professionals are not sufficiently informed of the digital technologies available today and how they and their patients can gain substantial benefit from adoption of these technologies. To raise awareness of the potential benefits of using digital technologies for improving practice efficiencies and patient health outcomes. Implementing best practice care for patients with chronic and complex conditions is one of the greatest challenges facing general practice and other primary care providers. It has been suggested that digital technologies could assist by decreasing the administrative burden of care delivery, improving quality of care, increasing practice efficiencies and better supporting patient self-management. In this paper, we consider some areas in the management of chronic and long-term conditions where digital and mobile health solutions can make a difference today.

"More than skin deep": stress neurobiology and mental health consequences of racial discrimination.

PubMed

Berger, Maximus; Sarnyai, Zoltán

2015-01-01

Ethnic minority groups across the world face a complex set of adverse social and psychological challenges linked to their minority status, often involving racial discrimination. Racial discrimination is increasingly recognized as an important contributing factor to health disparities among non-dominant ethnic minorities. A growing body of literature has recognized these health disparities and has investigated the relationship between racial discrimination and poor health outcomes. Chronically elevated cortisol levels and a dysregulated hypothalamic-pituitary-adrenal (HPA) axis appear to mediate effects of racial discrimination on allostatic load and disease. Racial discrimination seems to converge on the anterior cingulate cortex (ACC) and may impair the function of the prefrontal cortex (PFC), hence showing substantial similarities to chronic social stress. This review provides a summary of recent literature on hormonal and neural effects of racial discrimination and a synthesis of potential neurobiological pathways by which discrimination affects mental health.

One of the major challenges faced by the biomedical industry is the development of robust synthetic surfaces that can resist bacterial colonization. Much inspiration has been drawn recently from naturally occurring mechano-bactericidal surfaces such as the wings of cicada ( Psaltoda claripennis) and dragonfly ( Diplacodes bipunctata) species in fabricating their synthetic analogs. However, the bactericidal activity of nanostructured surfaces is observed in a particular range of parameters reflecting the geometry of nanostructures and surface wettability. Here, several of the nanometer-scale characteristics of black silicon (bSi) surfaces including the density and height of the nanopillars that have the potential to influence the bactericidal efficiency of these nanostructured surfaces have been investigated. The results provide important evidence that minor variations in the nanoarchitecture of substrata can substantially alter their performance as bactericidal surfaces.[Figure not available: see fulltext.

Shafer, Kevin; Wendt, Douglas

2015-04-01

Substantial attention is paid to the mental health needs of women and children by social work researchers, educators, and practitioners--and with good reason, as these are two vulnerable populations in U.S. society. However, the status of men's mental health; its resulting effect on individuals, families, and communities; and the various challenges associated with it are often overlooked by social workers. The authors document the prevalence of common mental health issues among men in the United States, the unique problems that men face, and help-seeking behaviors. They also discuss how social work is in an exceptional position to help men, and the systemic effects that social work practice with men can have. The authors assert that helping improve men's mental health is critical for social work, particularly given its values recognizing the dignity and worth of all individuals. Their goal is to raise awareness and spark an open dialogue about social work practice with men.

Compassion Fatigue in Adult Daughter Caregivers of a Parent with Dementia

Day, Jennifer R.; Anderson, Ruth A.; Davis, Linda L.

2015-01-01

Adult daughters face distinct challenges caring for parents with dementia and may experience compassion fatigue: the combination of helplessness, hopelessness, an inability to be empathic, and a sense of isolation resulting from prolonged exposure to perceived suffering. Prior research on compassion fatigue has focused on professional healthcare providers and has overlooked filial caregivers. This study attempts to identify and explore risk factors for compassion fatigue in adult daughter caregivers and to substantiate further study of compassion fatigue in family caregivers. We used content analysis of baseline interviews with 12 adult daughter caregivers of a parent with dementia who participated in a randomized trial of homecare training. Four themes were identified in adult daughter caregiver interviews: (a) uncertainty; (b) doubt; (c) attachment; and (d) strain. Findings indicated adult daughter caregivers are at risk for compassion fatigue, supporting the need for a larger study exploring compassion fatigue in this population. PMID:25259643

The role of research in helping general practice commission efficient healthcare

PubMed Central

2011-01-01

The new commissioning consortia face a major challenge in improving the efficiency of the NHS. They are new organisations, and at the same time as establishing themselves they need to overcome significant obstacles to reforming services. Research evidence about the value of care can help consortia achieve efficiencies, but there are often delays between the provision of evidence and its routine use in policy and practice. The National Institute for Health Research (NIHR) has invested substantial funding in providing evidence for the NHS, and in this article we discuss how consortia can make sure they obtain and apply relevant evidence as quickly as possible, and also generate evidence on practical questions such as the impact of redesigned services. Partnership with NIHR research organizations, particularly the Collaborations for Leadership in Applied Research and Care (CLAHRCs), offer one approach to helping consortia commission efficient health care.

Mineral inclusions in biomass are attracting increased scrutiny due to their potential impact on processing methods designed to provide renewable feedstocks for the production of chemicals and fuels. These inclusions are often sculpted by the plant into shapes required to support functional roles that include the storage of specific elements, strengthening of the plant structure, and providing a defense against pathogens and herbivores. In situ characterization of these inclusions faces substantial challenges since they are embedded in an opaque, complex polymeric matrix. Here we describe the use of Bragg coherent diffraction imaging (BCDI) to study mineral inclusions within intact maize stalks. Three-dimensional BCDI data sets were collected and used to reconstruct images of mineral inclusions at 50-100 nm resolution. Asymmetries in the intensity distributions around the Bragg peaks provided detailed information about the deformation fields within these crystal particles revealing lattice defects that result in distinct internal crystal domains.

Large carnivores face serious threats and are experiencing massive declines in their populations and geographic ranges around the world. We highlight how these threats have affected the conservation status and ecological functioning of the 31 largest mammalian carnivores on Earth. Consistent with theory, empirical studies increasingly show that large carnivores have substantial effects on the structure and function of diverse ecosystems. Significant cascading trophic interactions, mediated by their prey or sympatric mesopredators, arise when some of these carnivores are extirpated from or repatriated to ecosystems. Unexpected effects of trophic cascades on various taxa and processes include changes to bird, mammal, invertebrate, and herpetofauna abundance or richness; subsidies to scavengers; altered disease dynamics; carbon sequestration; modified stream morphology; and crop damage. Promoting tolerance and coexistence with large carnivores is a crucial societal challenge that will ultimately determine the fate of Earth's largest carnivores and all that depends upon them, including humans.

Pregnancy after breast cancer: a case study resolving the reproductive challenge with a gestational surrogate.

Krychman, Michael L; King, Tari

2006-01-01

Pregnancy and fertility issues are substantial concerns for the young breast cancer survivor, yet the available literature is hampered by a lack of prospective clinical studies and meaningful long-term outcome data. A lack of reliable information often leads to physician discomfort and patients may be left to navigate the world of fertility preservation and reproductive technology on their own. This case exemplifies some of the many issues that breast cancer survivors may face and adds another dimension to the survivor's dilemma; once fertility options have been preserved, what is the best method to sustain the pregnancy--self or surrogate? For many, the goal of balancing optimal treatment and long-term survival with restoration of a complete quality of life, including childbearing, may be attainable. This discussion highlights the importance of offering young breast cancer patients an opportunity to discuss these issues with their health care providers prior to initiating therapy.

Sarker, Goutam

2010-10-01

The objective of face detection is to identify all images which contain a face, irrespective of its orientation, illumination conditions etc. This is a hard problem, because the faces are highly variable in size, shape lighting conditions etc. Many methods have been designed and developed to detect faces in a single image. The present paper is based on one `Appearance Based Method' which relies on learning the facial and non facial features from image examples. This in its turn is based on statistical analysis of examples and counter examples of facial images and employs Bayesian Conditional Classification Rule to detect the probability of belongingness of a face (or non-face) within an image frame. The detection rate of the present system is very high and thereby the number of false positive and false negative detection is substantially low.

2014-01-01

Pharmacy education in Yemen has faced many challenges since its introduction in the 1980s. Most Yemeni pharmacy schools, especially private ones, are experiencing difficulties in providing the right quality and quantity of clinical educational experiences. Most of these challenges are imbedded in a teaching style and curricula that have failed to respond to the needs of the community and country. The slow shift from traditional drug-dispensing to a patient-centered or focused approach in pharmacy practice requires a fundamental change in the roles and responsibilities of both policymakers and educators. The purpose of this paper is twofold: (1) to discuss the challenges facing the pharmacy education in Yemen; (2) to provided recommendations to overcome challenges. PMID:25386011

Through the measure of thousands of small-molecule metabolites in diverse biological systems, metabolomics now offers the potential for new insights into the factors that contribute to complex human diseases such as cardiovascular disease. Targeted metabolomics methods have already identified new molecular markers and metabolomic signatures of cardiovascular disease risk (including branched-chain amino acids, select unsaturated lipid species, and trimethylamine- N -oxide), thus in effect linking diverse exposures such as those from dietary intake and the microbiota with cardiometabolic traits. As technologies for metabolomics continue to evolve, the depth and breadth of small-molecule metabolite profiling in complex systems continue to advance rapidly, along with prospects for ongoing discovery. Current challenges facing the field of metabolomics include scaling throughput and technical capacity for metabolomics approaches, bioinformatic and chemoinformatic tools for handling large-scale metabolomics data, methods for elucidating the biochemical structure and function of novel metabolites, and strategies for determining the true clinical relevance of metabolites observed in association with cardiovascular disease outcomes. Progress made in addressing these challenges will allow metabolomics the potential to substantially affect diagnostics and therapeutics in cardiovascular medicine. © 2017 American Heart Association, Inc.

Driven by the idea to offer better medical treatment for renal patients, technological innovations were developed and established that also constituted new challenges in the field of regulatory affairs. The existing regulations predominantly addressed the quality and safety of those products needed to perform dialysis treatment which were supplied by industrial manufacturers. However, the complexity of treatment system required for the provision of on-line fluids demanded a holistic approach encompassing all components involved. Hence, focus was placed not only on single products, but much more on their interfacing, and the clinical infrastructure, in particular, had to undergo substantial changes. The overall understanding of the interaction between such factors, quite different in their nature, was crucial to overcome the arising regulatory obstacles. This essay describes the evolution of the on-line HDF procedure from the regulatory point of view. A simplified diagram demonstrates the path taken from the former regulatory understanding to the realization of necessary changes. That achievement was only possible through 'management of preview' and consequent promotion of technical and medical innovations as well as regulatory re-evaluations. Copyright © 2011 S.

The interactions of lightweight flexible airframe structures, steady and unsteady aerodynamics, and wide-bandwidth active controls on modern airplanes lead to considerable multidisciplinary design challenges. More than 25 years of mathematical and numerical methods' development, numerous basic research studies, simulations and wind-tunnel tests of simple models, wind-tunnel tests of complex models of real airplanes, as well as flight tests of actively controlled airplanes, have all contributed to the accumulation of a substantial body of knowledge in the area of aeroservoelasticity. A number of analysis codes, with the capabilities to model real airplane systems under the assumptions of linearity, have been developed. Many tests have been conducted, and results were correlated with analytical predictions. A selective sample of references covering aeroservoelastic testing programs from the 1960s to the early 1980s, as well as more recent wind-tunnel test programs of real or realistic configurations, are included in the References section of this paper. An examination of references 20-29 will reveal that in the course of development (or later modification), of almost every modern airplane with a high authority active control system, there arose a need to face aeroservoelastic problems and aeroservoelastic design challenges.

Being socially connected directly impacts our basic needs and survival. People with deficits in social cognition might exhibit abnormal behaviors and face many challenges in our highly social-dependent world. These challenges and limitations are associated with a substantial economical and subjective impact. As many conditions where social cognition is affected are highly prevalent, more treatments have to be developed. Based on recent research, we review studies where non-invasive neuromodulatory techniques have been used to promote Social Plasticity in developmental disorders. We focused on three populations where non-invasive brain stimulation seems to be a promising approach in inducing social plasticity: Schizophrenia, Autism Spectrum Disorder (ASD) and Williams Syndrome (WS). There are still very few studies directly evaluating the effects of transcranial direct current stimulation (tDCS) and transcranial magnetic stimulation (TMS) in the social cognition of these populations. However, when considering the promising preliminary evidences presented in this review and the limited amount of clinical interventions available for treating social cognition deficits in these populations today, it is clear that the social neuroscientist arsenal may profit from non-invasive brain stimulation techniques for rehabilitation and promotion of social plasticity.

Market trend data show that the media marketplace continues to rapidly evolve. Recent research shows that substantial portions of the U.S. media population are "new media" users. Today, more than ever before, media consumers are exposed to multiple media at the same point in time, encouraged to participate in media content generation, and challenged to learn, access, and use the new media that are continually entering the market. These media trends have strong implications for how consumers of health information access, process, and retain health-related knowledge. In this article we review traditional information processing models and theories of interpersonal and mass media access and consumption. We make several theory-based propositions for how traditional information processing and media consumption concepts will function as new media usage continues to increase. These propositions are supported by new media usage data from the Centers for Disease Control and Prevention's entry into the new media market (e.g., podcasting, virtual events, blogging, and webinars). Based on these propositions, we conclude by presenting both opportunities and challenges that public health communicators and marketers will face in the future.

Exploring the MACH Model’s Potential as a Metacognitive Tool to Help Undergraduate Students Monitor Their Explanations of Biological Mechanisms

When undergraduate biology students learn to explain biological mechanisms, they face many challenges and may overestimate their understanding of living systems. Previously, we developed the MACH model of four components used by expert biologists to explain mechanisms: Methods, Analogies, Context, and How. This study explores the implementation of the model in an undergraduate biology classroom as an educational tool to address some of the known challenges. To find out how well students’ written explanations represent components of the MACH model before and after they were taught about it and why students think the MACH model was useful, we conducted an exploratory multiple case study with four interview participants. We characterize how two students explained biological mechanisms before and after a teaching intervention that used the MACH components. Inductive analysis of written explanations and interviews showed that MACH acted as an effective metacognitive tool for all four students by helping them to monitor their understanding, communicate explanations, and identify explanatory gaps. Further research, though, is needed to more fully substantiate the general usefulness of MACH for promoting students’ metacognition about their understanding of biological mechanisms. PMID:27252295

Coeliac disease is a global disease, and the only currently available treatment is a gluten-free diet (GFD). Although conceptually simple, the diet changes are substantial and have a profound effect on a patient's life. Untreated coeliac disease is associated with complications, including excess mortality, most of which can be avoided with a strict GFD. However, there are many barriers, including availability, cost and safety of gluten-free foods, and gluten cross-contamination. The GFD can be restrictive in social situations, leading to poor quality of life and, ultimately, nonadherence. As the number of patients with coeliac disease increases worldwide, clinicians need to be aware of the challenges patients face. Heightened awareness by physicians, dietitians and other providers can help maximize successful treatment, improve outcomes, and reduce health-care costs and disease burden. Routine follow-up is necessary to reinforce the need for a GFD, provide social and emotional support, and achieve mucosal healing, leading to reduced risk of complications. Unfortunately, there is wide variation in follow-up practices. The objective of this Review is to increase awareness of the challenges, management and follow-up of patients with coeliac disease to help them achieve GFD adherence and prevent complications whilst preserving their quality of life.

Culture shapes social cognition in many ways. Yet cultural impact on face tuning remains largely unclear. Here typically developing females and males from the French-speaking part of Switzerland were presented with a set of Arcimboldo-like Face-n-Food images composed of food ingredients and in different degree resembling a face. The outcome had been compared with previous findings obtained in young adults of the South-West Germany. In that study, males exhibit higher thresholds for face tuning on the Face-n-Food task than females. In Swiss participants, no gender differences exist in face tuning. Strikingly, males from the French-speaking part of Switzerland possess higher sensitivity to faces than their German peers, whereas no difference in face tuning occurs between females. The outcome indicates that even relatively subtle cultural differences as well as culture by gender interaction can modulate social cognition. Clarification of the nature of cultural impact on face tuning as well as social cognition at large is of substantial value for understanding a wide range of neuropsychiatric and neurodevelopmental conditions.

The involvement of the gamma-aminobutyric acid (GABA) system in schizophrenia is suggested by postmortem studies and the common use of GABA receptor-potentiating agents in treatment. In a recent study, we used a benzodiazepine challenge to demonstrate abnormal GABAergic function during processing of negative visual stimuli in schizophrenia. This study extended this investigation by mapping GABAergic mechanisms associated with face processing and social appraisal in schizophrenia using a benzodiazepine challenge. Fourteen stable, medicated schizophrenia/schizoaffective patients (SZ) and 13 healthy controls (HC) underwent functional MRI using the blood oxygenation level-dependent (BOLD) technique while they performed the Socio-emotional Preference Task (SePT) on emotional face stimuli ("Do you like this face?"). Participants received single-blinded intravenous saline and lorazepam (LRZ) in two separate sessions separated by 1-3weeks. Both SZ and HC recruited medial prefrontal cortex/anterior cingulate during the SePT, relative to gender identification. A significant drug by group interaction was observed in the medial occipital cortex, such that SZ showed increased BOLD signal to LRZ challenge, while HC showed an expected decrease of signal; the interaction did not vary by task. The altered BOLD response to LRZ challenge in SZ was significantly correlated with increased negative affect across multiple measures. The altered response to LRZ challenge suggests that abnormal face processing and negative affect in SZ are associated with altered GABAergic function in the visual cortex, underscoring the role of impaired visual processing in socio-emotional deficits in schizophrenia.

Background U-CARE is a multidisciplinary eHealth research program that involves the disciplines of caring science, clinical psychology, health economics, information systems, and medical science. It was set up from scratch in a university setting in 2010, funded by a governmental initiative. While establishing the research program, many challenges were faced. Systematic documentation of experiences from establishing new research environments is scarce. Objective The aim of this paper was to describe the challenges of establishing a publicly funded multidisciplinary eHealth research environment. Methods Researchers involved in developing the research program U-CARE identified challenges in the formal documentation and by reflecting on their experience of developing the program. The authors discussed the content and organization of challenges into themes until consensus was reached. Results The authors identified 15 major challenges, some general to establishing a new research environment and some specific for multidisciplinary eHealth programs. The challenges were organized into 6 themes: Organization, Communication, Implementation, Legislation, Software development, and Multidisciplinarity. Conclusions Several challenges were faced during the development of the program and several accomplishments were made. By sharing our experience, we hope to help other research groups embarking on a similar journey to be prepared for some of the challenges they are likely to face on their way. PMID:28536090

Taxonomy of Challenges for Digital Forensics.

Karie, Nickson M; Venter, Hein S

2015-07-01

Since its inception, over a decade ago, the field of digital forensics has faced numerous challenges. Despite different researchers and digital forensic practitioners having studied and analysed various known digital forensic challenges, as of 2013, there still exists a need for a formal classification of these challenges. This article therefore reviews existing research literature and highlights the various challenges that digital forensics has faced for the last 10 years. In conducting this research study, however, it was difficult for the authors to review all the existing research literature in the digital forensic domain; hence, sampling and randomization techniques were employed to facilitate the review of the gathered literature. Taxonomy of the various challenges is subsequently proposed in this paper based on our review of the literature. The taxonomy classifies the large number of digital forensic challenges into four well-defined and easily understood categories. The proposed taxonomy can be useful, for example, in future developments of automated digital forensic tools by explicitly describing processes and procedures that focus on addressing specific challenges identified in this paper. However, it should also be noted that the purpose of this paper was not to propose any solutions to the individual challenges that digital forensics face, but to serve as a survey of the state of the art of the research area. © 2015 American Academy of Forensic Sciences.

Abstract Oral HIV pre-exposure prophylaxis (PrEP) is a promising new biomedical prevention approach in which HIV-negative individuals are provided with daily oral antiretroviral medication for the primary prevention of HIV-1. Several clinical trials have demonstrated efficacy of oral PrEP for HIV prevention among groups at high risk for HIV, with adherence closely associated with level of risk reduction. In the United States (US), three groups have been prioritized for initial implementation of PrEP—injection drug users, men who have sex with men at substantial risk for HIV, and HIV-negative partners within serodiscordant heterosexual couples. Numerous demonstration projects involving PrEP implementation among MSM are underway, but relatively little research has been devoted to study PrEP implementation in HIV-serodiscordant heterosexual couples in the US. Such couples face a unique set of challenges to PrEP implementation at the individual, couple, and provider level with regard to PrEP uptake and maintenance, adherence, safety and toxicity, clinical monitoring, and sexual risk behavior. Oral PrEP also provides new opportunities for serodiscordant couples and healthcare providers for primary prevention and reproductive health. This article provides a review of the critical issues, challenges, and opportunities involved in the implementation of oral PrEP among HIV-serodiscordant heterosexual couples in the US.

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.

Getting rid of the unwanted: highlights of developments and challenges of biobeneficiation of iron ore minerals-a review.

PubMed

Adeleke, Rasheed A

2014-12-01

The quest for quality mineral resources has led to the development of many technologies that can be used to refine minerals. Biohydrometallurgy is becoming an increasingly acceptable technology worldwide because it is cheap and environmentally friendly. This technology has been successfully developed for some sulphidic minerals such as gold and copper. In spite of wide acceptability of this technology, there are limitations to its applications especially in the treatment of non-sulphidic minerals such as iron ore minerals. High levels of elements such as potassium (K) and phosphorus (P) in iron ore minerals are known to reduce the quality and price of these minerals. Hydrometallurgical methods that are non-biological involving the use of chemicals are usually used to deal with this problem. However, recent advances in mining technologies favour green technologies, known as biohydrometallurgy, with minimal impact on the environment. This technology can be divided into two, namely bioleaching and biobeneficiation. This review focuses on Biobeneficiation of iron ore minerals. Biobeneficiation of iron ore is very challenging due to the low price and chemical constitution of the ore. There are substantial interests in the exploration of this technology for improving the quality of iron ore minerals. In this review, current developments in the biobeneficiation of iron ore minerals are considered, and potential solutions to challenges faced in the wider adoption of this technology are proposed.

Purpose The population, and needs, of informal carers is changing, reflecting not only the changing demographics across Europe, but also the unequal challenges and opportunities for education and training—and official approval of competences—across Europe for people involved in the care sector, formal as well as informal carers. Theory The objective of this European project (Austria, France, Lithuania Luxembourg, Poland and Spain) was to create, offer and evaluate an education and training programme specifically aimed at informal carers (e.g. family members), providing answers to meet their real needs in their support work as well as for their own emotional well-being. Therefore, project partners produced six innovative, online supported training modules (total 60 hours) for face-to-face delivery. Methods The presentation will highlight the development and the content of one training Module for older people with ‘intellectual disabilities’ more detailed. Results and conclusions All trainings were evaluated by the participants through pre/post questionnaires. The results of the trainings will be presented. Discussion The importance of trainings and support for informal carers will be discussed with special emphasis given on the fact that informal carers represent a most substantial economic resource for every country and its care system.

Communication and cooperation in networked environments: an experimental analysis.

Interpersonal communication and cooperation do not happen exclusively face to face. In work contexts, as in private life, there are more and more situations of mediated communication and cooperation in which new online tools are used. However, understanding how to use the Internet to support collaborative interaction presents a substantial challenge for the designers and users of this emerging technology. First, collaborative Internet environments are designed to serve a purpose, so must be designed with intended users' tasks and goals explicitly considered. Second, in cooperative activities the key content of communication is the interpretation of the situations in which actors are involved. So, the most effective way of clarifying the meaning of messages is to connect them to a shared context of meaning. However, this is more difficult in the Internet than in other computer-based activities. This paper tries to understand the characteristics of cooperative activities in networked environments--shared 3D virtual worlds--through two different studies. The first used the analysis of conversations to explore the characteristics of the interaction during the cooperative task; the second analyzed whether and how the level of immersion in the networked environments influenced the performance and the interactional process. The results are analyzed to identify the psychosocial roots used to support cooperation in a digital interactive communication.

Hyperspectral face recognition with spatiospectral information fusion and PLS regression.

Hyperspectral imaging offers new opportunities for face recognition via improved discrimination along the spectral dimension. However, it poses new challenges, including low signal-to-noise ratio, interband misalignment, and high data dimensionality. Due to these challenges, the literature on hyperspectral face recognition is not only sparse but is limited to ad hoc dimensionality reduction techniques and lacks comprehensive evaluation. We propose a hyperspectral face recognition algorithm using a spatiospectral covariance for band fusion and partial least square regression for classification. Moreover, we extend 13 existing face recognition techniques, for the first time, to perform hyperspectral face recognition.We formulate hyperspectral face recognition as an image-set classification problem and evaluate the performance of seven state-of-the-art image-set classification techniques. We also test six state-of-the-art grayscale and RGB (color) face recognition algorithms after applying fusion techniques on hyperspectral images. Comparison with the 13 extended and five existing hyperspectral face recognition techniques on three standard data sets show that the proposed algorithm outperforms all by a significant margin. Finally, we perform band selection experiments to find the most discriminative bands in the visible and near infrared response spectrum.

2015-11-15

Marine protected areas (MPAs) face many challenges in their aim to effectively conserve marine ecosystems. In this study we analyze the extent of pollution exposure on the global fleet of MPAs. This includes indicators for current and future pollution and the implications for regionally clustered groups of MPAs with similar biophysical characteristics. To cluster MPAs into characteristic signature groups, their bathymetry, baseline biodiversity, distance from shore, mean sea surface temperature and mean sea surface salinity were used. We assess the extent at which each signature group is facing exposure from multiple pollution types. MPA groups experience similar pollution exposure on a regional level. We highlight how the challenges that MPAs face can be addressed through governance at the appropriate scale and design considerations for integrated terrestrial and marine management approaches within regional level networks. Furthermore, we present diagnostic social-ecological indicators for addressing the challenges facing unsuccessful MPAs with practical applications. Copyright © 2015 Elsevier Ltd.

We present a comprehensive review of published results from the last 30 years regarding the sources and atmospheric characteristics of particles and ozone in the Metropolitan Area of São Paulo (MASP). During the last 30 years, many efforts have been made to describe the emissions sources and to analyse the primary and secondary formation of pollutants under a process of increasing urbanisation in the metropolitan area. From the occurrence of frequent violations of air quality standards in the 1970s and 1980s (due to the uncontrolled air pollution sources) to a substantial decrease in the concentrations of the primary pollutants, many regulations have been imposed and enforced, although those concentrations do not yet conform to the World Health Organization guidelines. The greatest challenge currently faced by the São Paulo State Environmental Protection Agency and the local community is controlling secondary pollutants such as ozone and fine particles. Understanding the formation of these secondary pollutants, by experimental or modelling approaches, requires the description of the atmospheric chemical processes driven by biofuel, ethanol and biodiesel emissions. Exposure to air pollution is the cause of many injuries to human health, according to many studies performed not only in the region but also worldwide, and affects susceptible populations such as children and the elderly. The MASP is the biggest megacity in the Southern Hemisphere, and its specifics are important for other urban areas that are facing the challenge of intensive growth that puts pressure on natural resources and worsens the living conditions in urban areas. This text discusses how imposing regulations on air quality and emission sources, mainly related to the transportation sector, has affected the evolution of pollutant concentrations in the MASP.

Exploring the experiences and coping strategies of international medical students

PubMed Central

2011-01-01

Background Few studies have addressed the challenges that international medical students face and there is a dearth of information on the behavioural strategies these students adopt to successfully progress through their academic program in the face of substantial difficulties of language barrier, curriculum overload, financial constraints and assessment tasks that require high proficiency in communication skills. Methods This study was designed primarily with the aim of enhancing understanding of the coping strategies, skill perceptions and knowledge of assessment expectations of international students as they progress through the third and fourth years of their medical degree at the School of Medicine, University of Tasmania, Australia. Results Survey, focus group discussion and individual interviews revealed that language barriers, communication skills, cultural differences, financial burdens, heavy workloads and discriminatory bottlenecks were key factors that hindered their adaptation to the Australian culture. Quantitative analyses of their examination results showed that there were highly significant (p < 0.001) variations between student performances in multiple choice questions, short answer questions and objective structured clinical examinations (70.3%, 49.7% & 61.7% respectively), indicating existence of communication issues. Conclusions Despite the challenges, these students have adopted commendable coping strategies and progressed through the course largely due to their high sense of responsibility towards their family, their focus on the goal of graduating as medical doctors and their support networks. It was concluded that faculty needs to provide both academic and moral support to their international medical students at three major intervention points, namely point of entry, mid way through the course and at the end of the course to enhance their coping skills and academic progression. Finally, appropriate recommendations were made. PMID:21702988

A mechanical seal (e.g., single mechanical seals, double mechanical seals, tandem mechanical seals, bellows, pusher mechanical seals, and all types of rotating and reciprocating machines) with reduced contact surface temperature, reduced contact surface wear, or increased life span. The mechanical seal comprises a rotating ring and a single-piece, perforated mating ring, which improves heat transfer by controllably channeling coolant flow through the single-piece mating ring such that the coolant is in substantially uniform thermal contact with a substantial portion of the interior surface area of the seal face, while maintaining the structural integrity of the mechanical seal and minimizing the potential for coolant flow interruptions to the seal face caused by debris or contaminants (e.g., small solids and trash) in the coolant.

Griebel, Philip J

2015-06-01

The control and prevention of bovine viral diarrhea virus (BVDV) infections has provided substantial challenges. Viral genetic variation, persistent infections, and viral tropism for immune cells have complicated disease control strategies. Vaccination has, however, provided an effective tool to prevent acute systemic infections and increase reproductive efficiency through fetal protection. There has been substantial controversy about the safety and efficacy of BVDV vaccines, especially when comparing killed versus modified-live viral (MLV) vaccines. Furthermore, numerous vaccination protocols have been proposed to protect the fetus and ensure maternal antibody transfer to the calf. These issues have been further complicated by reports of immune suppression during natural infections and following vaccination. While killed BVDV vaccines provide the greatest safety, their limited immunogenicity makes multiple vaccinations necessary. In contrast, MLV BVDV vaccines induce a broader range of immune responses with a longer duration of immunity, but require strategic vaccination to minimize potential risks. Vaccination strategies for breeding females and young calves, in the face of maternal antibody, are discussed. With intranasal vaccination of young calves it is possible to avoid maternal antibody interference and induce immune memory that persists for 6-8 months. Thus, with an integrated vaccination protocol for both breeding cows and calves it is possible to maximize disease protection while minimizing vaccine risks.

NASA's Vision for Potential Energy Reduction from Future Generations of Propulsion Technology

NASA Technical Reports Server (NTRS)

Haller, Bill

2015-01-01

Through a robust partnership with the aviation industry, over the past 50 years NASA programs have helped foster advances in propulsion technology that enabled substantial reductions in fuel consumption for commercial transports. Emerging global trends and continuing environmental concerns are creating challenges that will very likely transform the face of aviation over the next 20-40 years. In recognition of this development, NASA Aeronautics has established a set of Research Thrusts that will help define the future direction of the agency's research technology efforts. Two of these thrusts, Ultra-Efficient Commercial Vehicles and Transition to Low-Carbon Propulsion, serve as cornerstones for the Advanced Air Transport Technology (AATT) project. The AATT project is exploring and developing high-payoff technologies and concepts that are key to continued improvement in energy efficiency and environmental compatibility for future generations of fixed-wing, subsonic transports. The AATT project is primarily focused on the N+3 timeframe, or 3 generations from current technology levels. As should be expected, many of the propulsion system architectures technologies envisioned for N+3 vary significantly from todays engines. The use of batteries in a hybrid-electric configuration or deploying multiple fans distributed across the airframe to enable higher bypass ratios are just two examples of potential advances that could enable substantial energy reductions over current propulsion systems.

Kratz, Lyn; Uding, Nancy; Trahms, Cristine M; Villareale, Nanci; Kieckhefer, Gail M

2009-12-01

When children have special health care needs, parents assume the roles of care coordinator, medical expert, and systems advocate as well as their typical parenting roles. They face many challenges in managing their child's chronic condition in the context of everyday life. Health care providers are uniquely positioned to assist parents in meeting those challenges and to promote parent competency and confidence in their child's care. The data for this analysis were collected during classes for parents of children with chronic conditions who took part in a randomized controlled study of a curriculum's effectiveness. During facilitated discussions, parents discussed challenges they faced and generated strategies they found helpful. Qualitative data analysis revealed dominant themes across subject areas. Challenges included social isolation, strained relationships and ongoing frustrations with health care and educational systems. Helpful strategies focused on being prepared, connecting with peers, becoming an advocate, developing partnerships and caring for one's self. Implications for health care providers include: understanding common challenges parents face; promoting parent-to-parent connections; and building partnerships with parents and their children with special needs.

Enhanced facial texture illumination normalization for face recognition.

PubMed

Luo, Yong; Guan, Ye-Peng

2015-08-01

An uncontrolled lighting condition is one of the most critical challenges for practical face recognition applications. An enhanced facial texture illumination normalization method is put forward to resolve this challenge. An adaptive relighting algorithm is developed to improve the brightness uniformity of face images. Facial texture is extracted by using an illumination estimation difference algorithm. An anisotropic histogram-stretching algorithm is proposed to minimize the intraclass distance of facial skin and maximize the dynamic range of facial texture distribution. Compared with the existing methods, the proposed method can more effectively eliminate the redundant information of facial skin and illumination. Extensive experiments show that the proposed method has superior performance in normalizing illumination variation and enhancing facial texture features for illumination-insensitive face recognition.

Plasma Material Interactions in future fusion reactors have been identified as a knowledge gap to be dealt with before any next step device past ITER can be built. The challenges are manifold. They are related to power dissipation so that the heat fluxes to the plasma facing components can be kept at technologically feasible levels; maximization of the lifetime of divertor plasma facing components that allow for steady-state operation in a reactor to reach the neutron fluences required; the tritium inventory (storage) in the plasma facing components, which can lead to potential safety concerns and reduction in the fuel efficiency;more » and it is related to the technology of the plasma facing components itself, which should demonstrate structural integrity under the high temperatures and neutron fluence. This contribution will give an overview and summary of those challenges together with some discussion of potential solutions. New linear plasma devices are needed to investigate the PMI under fusion reactor conditions and test novel plasma facing components.

Impact of Wind and Solar on the Value of Energy Storage

DOE Office of Scientific and Technical Information (OSTI.GOV)

Denholm, Paul; Jorgenson, Jennie; Hummon, Marissa

2013-11-01

This analysis evaluates how the value of energy storage changes when adding variable generation (VG) renewable energy resources to the grid. A series of VG energy penetration scenarios from 16% to 55% were generated for a utility system in the western United States. This operational value of storage (measured by its ability to reduce system production costs) was estimated in each VG scenario, considering provision of different services and with several sensitivities to fuel price and generation mix. Overall, the results found that the presence of VG increases the value of energy storage by lowering off-peak energy prices more thanmore » on-peak prices, leading to a greater opportunity to arbitrage this price difference. However, significant charging from renewables, and consequently a net reduction in carbon emissions, did not occur until VG penetration was in the range of 40%-50%. Increased penetration of VG also increases the potential value of storage when providing reserves, mainly by increasing the amount of reserves required by the system. Despite this increase in value, storage may face challenges in capturing the full benefits it provides. Due to suppression of on-/off-peak price differentials, reserve prices, and incomplete capture of certain system benefits (such as the cost of power plant starts), the revenue obtained by storage in a market setting appears to be substantially less than the net benefit (reduction in production costs) provided to the system. Furthermore, it is unclear how storage will actually incentivize large-scale deployment of renewables needed to substantially increase VG penetration. This demonstrates some of the additional challenges for storage deployed in restructured energy markets.« less

World Health Organization perspectives on the contribution of the Global Alliance for Vaccines and Immunization on reducing child mortality.

Bustreo, F; Okwo-Bele, J-M; Kamara, L

2015-02-01

Child mortality has decreased substantially globally-from 12.6 million in 1990 to 6.3 million in 2013-due, in large part to of governments' and organisations' work, to prevent pneumonia, diarrhoea and malaria, the main causes of death in the postneonatal period. In 2012, the World Health Assembly adopted the Decade of Vaccines Global Vaccine Action Plan 2011-2020 as the current framework aimed at preventing millions of deaths through more equitable access to existing vaccines for people in all communities. The Global Alliance for Vaccines and Immunization (GAVI) plays a critical role in this effort by financing and facilitating delivery platforms for vaccines, with focused support for the achievements of improved vaccination coverage and acceleration of the uptake of WHO-recommended lifesaving new vaccines in 73 low-income countries. The GAVI Alliance has contributed substantially towards the progress of Millennium Development Goal 4 and to improving women's lives. By 2013, the GAVI Alliance had immunised 440 million additional children and averted six million future deaths from vaccine-preventable diseases in the world's poorest countries. The GAVI Alliance is on track to reducing child mortality to 68 per 1000 live births by 2015 in supported countries. This paper discusses the GAVI Alliance achievements related to Millennium Development Goal 4 and its broader contribution to improving women's lives and health systems, as well as challenges and obstacles it has faced. Additionally, it looks at challenges for the future and how it will continue its work related to reducing child mortality and improving women's health. Published by the BMJ Publishing Group Limited.

India and China face the same challenge of having too few trained psychiatric personnel to manage effectively the substantial burden of mental illness within their population. At the same time, both countries have many practitioners of traditional, complementary, and alternative medicine who are a potential resource for delivery of mental health care. In our paper, part of The Lancet and Lancet Psychiatry's Series about the China-India Mental Health Alliance, we describe and compare types of traditional, complementary, and alternative medicine in India and China. Further, we provide a systematic overview of evidence assessing the effectiveness of these alternative approaches for mental illness and discuss challenges in research. We suggest how practitioners of traditional, complementary, and alternative medicine and mental health professionals might forge collaborative relationships to provide more accessible, affordable, and acceptable mental health care in India and China. A substantial proportion of individuals with mental illness use traditional, complementary, and alternative medicine, either exclusively or with biomedicine, for reasons ranging from faith and cultural congruence to accessibility, cost, and belief that these approaches are safe. Systematic reviews of the effectiveness of traditional, complementary, and alternative medicine find several approaches to be promising for treatment of mental illness, but most clinical trials included in these systematic reviews have methodological limitations. Contemporary methods to establish efficacy and safety-typically through randomised controlled trials-need to be complemented by other means. The community of practice built on collaborative relationships between practitioners of traditional, complementary, and alternative medicine and providers of mental health care holds promise in bridging the treatment gap in mental health care in India and China.

How stable is activation in the amygdala and prefrontal cortex in adolescence? A study of emotional face processing across three measurements.

PubMed

2013-04-01

Prior developmental functional magnetic resonance imaging (fMRI) studies have demonstrated elevated activation patterns in the amygdala and prefrontal cortex (PFC) in response to viewing emotional faces. As adolescence is a time of substantial variability in mood and emotional responsiveness, the stability of activation patterns could be fluctuating over time. In the current study, 27 healthy adolescents (age: 12-19 years) were scanned three times over a period of six months (mean test-retest interval of three months; final samples N=27, N=22, N=18). At each session, participants performed the same emotional faces task. At first measurement the presentation of emotional faces resulted in heightened activation in bilateral amygdala, bilateral lateral PFC and visual areas including the fusiform face area. Average activation did not differ across test-sessions over time, indicating that at the group level activation patterns in this network do not vary significantly over time. However, using the Intraclass Correlation Coefficient (ICC), fMRI reliability demonstrated only fair reliability for PFC (ICC=0.41-0.59) and poor reliability for the amygdala (ICC<0.4). These findings suggest substantial variability of brain activity over time and may have implications for studies investigating the influence of treatment effects on changes in neural levels in adolescents with psychiatric disorders.

Emotion and Destination Memory in Alzheimer's Disease.

PubMed

El Haj, Mohamad; Raffard, Stephane; Antoine, Pascal; Gely-Nargeot, Marie-Christine

2015-01-01

Research shows beneficial effect of emotion on self-related information in patients with Alzheimer's Disease (AD). Our paper investigates whether emotion improves destination memory (e.g., did I tell you about the manuscript?), which is thought to be self-related (e.g., did I tell you about the manuscript?). To this aim, twenty-seven AD patients and thirty healthy older adults told 24 neutral facts to eight neutral faces, eight positive faces, and eight negative faces. On a subsequent recognition task, participants had to decide whether they had previously told a given fact to a given face or not. Data revealed no emotional effect on destination memory in AD patients. However, in healthy older adults, better destination memory was observed for negative faces than for positive faces, and the latter memory was better than for neutral faces. The absence of emotional effect on destination memory in AD is interpreted in terms of substantial decline in this memory in the disease.

Face identification with frequency domain matched filtering in mobile environments

NASA Astrophysics Data System (ADS)

Lee, Dong-Su; Woo, Yong-Hyun; Yeom, Seokwon; Kim, Shin-Hwan

2012-06-01

Face identification at a distance is very challenging since captured images are often degraded by blur and noise. Furthermore, the computational resources and memory are often limited in the mobile environments. Thus, it is very challenging to develop a real-time face identification system on the mobile device. This paper discusses face identification based on frequency domain matched filtering in the mobile environments. Face identification is performed by the linear or phase-only matched filter and sequential verification stages. The candidate window regions are decided by the major peaks of the linear or phase-only matched filtering outputs. The sequential stages comprise a skin-color test and an edge mask filtering test, which verify color and shape information of the candidate regions in order to remove false alarms. All algorithms are built on the mobile device using Android platform. The preliminary results show that face identification of East Asian people can be performed successfully in the mobile environments.

This study examined the levels of intimacy reported by individuals in face-to-face and computer-mediated (or "virtual") romantic relationships. As suggested by the media and promised by online dating services, some degree of intimacy was reported in computer-mediated relationships, but stronger intimacy was reported in all participants' face-to-face relationships. Results also indicated that individuals who had online, virtual relationships reported less intimacy in their own face-to-face relationships compared to individuals who had engaged exclusively in face-to-face relationships, suggesting that people may turn to virtual relating after challenges in their face-to-face experiences.

2010-11-01

In this article I argue that the future of psychological research on educational processes would benefit from an interdisciplinary approach that enables psychologists to locate their objects of study within the cultural, social, and historical contexts of their research. To make this argument, I begin by examining anthropological accounts of the characteristics of education in small, face-to-face, preindustrial societies. I then turn to a sample of contemporary psychoeducational research that seeks to implement major, qualitative changes in modern educational practices by transforming them to have the properties of education in those self-same face-to-face societies. Next I examine the challenges faced by these modern approaches and briefly describe a multi-institutional, multidisciplinary system of education that responds to these challenges while offering a model for educating psychology students in a multigenerational system of activities with potential widespread benefits.

Industrial Development and Challenges of Water Pollution in Coastal Areas: The Case of Surat, India

NASA Astrophysics Data System (ADS)

Bansal, Neeru

2018-03-01

Industrialisation plays an important role in the economic development of a country, however, pollution is the inevitable price paid for this development. Surat, a major industrial hub in western India, is located on the bank of the river Tapi and extends up to the Arabian Sea. The city is characterised by the presence of a number of creeks (known as ‘khadis’ in local language). This paper focusses on the industrial development in Surat and the challenges faced by the city due to water pollution. A constant deterioration in the quality of surface water resources has been observed due to discharge of treated or partially treated effluents from the industries. The problem of water pollution becomes critical due to increase in frequency of flooding, risks faced by the city due to climate change and the ineffective environmental governance. The paper provides insights into the challenges faced by the city and the learnings can lead to adoption of policy initiatives and other measures which can effectively address these challenges.

USGS Science: Addressing Our Nation's Challenges

USGS Publications Warehouse

Larson, Tania M.

2009-01-01

With 6.6 billion people already living on Earth, and that number increasing every day, human influence on our planet is ever more apparent. Changes to the natural world combined with increasing human demands threaten our health and safety, our national security, our economy, and our quality of life. As a planet and a Nation, we face unprecedented challenges: loss of critical and unique ecosystems, the effects of climate change, increasing demand for limited energy and mineral resources, increasing vulnerability to natural hazards, the effects of emerging diseases on wildlife and human health, and growing needs for clean water. The time to respond to these challenges is now, but policymakers and decisionmakers face difficult choices. With competing priorities to balance, and potentially serious - perhaps irreversible - consequences at stake, our leaders need reliable scientific information to guide their decisions. As the Nation's earth and natural science agency, the USGS monitors and conducts scientific research on natural hazards and resources and how these elements and human activities influence our environment. Because the challenges we face are complex, the science needed to better understand and deal with these challenges must reflect the complex interplay among natural and human systems. With world-class expertise in biology, geology, geography, hydrology, geospatial information, and remote sensing, the USGS is uniquely capable of conducting the comprehensive scientific research needed to better understand the interdependent interactions of Earth's systems. Every day, the USGS helps decisionmakers to minimize loss of life and property, manage our natural resources, and protect and enhance our quality of life. This brochure provides examples of the challenges we face and how USGS science helps decisionmakers to address these challenges.

Soil-water dynamics and unsaturated storage during snowmelt following wildfire

USGS Publications Warehouse

Ebel, Brian A.; Hinckley, E.S.; Martin, Deborah

2012-01-01

Many forested watersheds with a substantial fraction of precipitation delivered as snow have the potential for landscape disturbance by wildfire. Little is known about the immediate effects of wildfire on snowmelt and near-surface hydrologic responses, including soil-water storage. Montane systems at the rain-snow transition have soil-water dynamics that are further complicated during the snowmelt period by strong aspect controls on snowmelt and soil thawing. Here we present data from field measurements of snow hydrology and subsurface hydrologic and temperature responses during the first winter and spring after the September 2010 Fourmile Canyon Fire in Colorado, USA. Our observations of soil-water content and soil temperature show sharp contrasts in hydrologic and thermal conditions between north- and south-facing slopes. South-facing burned soils were ∼1–2 °C warmer on average than north-facing burned soils and ∼1.5 °C warmer than south-facing unburned soils, which affected soil thawing during the snowmelt period. Soil-water dynamics also differed by aspect: in response to soil thawing, soil-water content increased approximately one month earlier on south-facing burned slopes than on north-facing burned slopes. While aspect and wildfire affect soil-water dynamics during snowmelt, soil-water storage at the end of the snowmelt period reached the value at field capacity for each plot, suggesting that post-snowmelt unsaturated storage was not substantially influenced by aspect in wildfire-affected areas. Our data and analysis indicate that the amount of snowmelt-driven groundwater recharge may be larger in wildfire-impacted areas, especially on south-facing slopes, because of earlier soil thaw and longer durations of soil-water contents above field capacity in those areas.

Introduction 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. Methods 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. Results 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. Conclusion 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. PMID:23576933

Recommendations on Arresting Global Health Challenges Facing Adolescents and Young Adults.

PubMed

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.

This article describes and discusses the challenges faced by researchers who conducted a qualitative interview study on attitudes toward suicide among the Baganda, Uganda. Many of the challenges addressed in this article have not been described earlier in suicide research conducted in the developing world. The aim of this study was to explore attitudes and cultural responses toward suicide among the Baganda, Uganda. Data were collected and analyzed using grounded theory. A total of 28 focus group discussions and 30 key informant interviews were conducted. The findings of this study are organized under two broad categories: community access challenges and expectation challenges. Community access challenges entailed cultural, legal, rapport, informed consent, language, and other research process related issues that could hinder effective access to the study respondents. Expectation challenges concerned how to deal with the immediate and strategic needs of the study communities. This study demonstrates that culturally sensitive approaches to data collection can reduce ethical challenges and, through innovative approaches, practical challenges faced during data collection can be minimized.

Abstract Problem As countries expand health insurance coverage, their expenditures on medicines increase. To address this problem, WHO has recommended that every country draw up a list of essential medicines. Although most medicines on the list are generics, in many countries patented medicines represent a substantial portion of pharmaceutical expenditure. Approach To help control expenditure on patented medicines, in 2008 the Mexican Government created the Coordinating Commission for Negotiating the Price of Medicines and other Health Inputs (CCPNM), whose role, as the name suggests, is to enter into price negotiations with drug manufacturers for patented drugs on Mexico’s list of essential medicines. Local setting Mexico’s public expenditure on pharmaceuticals has increased substantially in the past decade owing to government efforts to achieve universal health-care coverage through Seguro Popular, an insurance programme introduced in 2004 that guarantees access to a comprehensive package of health services and medicines. Relevant changes Since 2008, the CCPNM has improved procurement practices in Mexico’s public health institutions and has achieved significant price reductions resulting in substantial savings in public pharmaceutical expenditure. Lessons learnt The CCPNM has successfully changed the landscape of price negotiation for patented medicines in Mexico. However, it is also facing challenges, including a lack of explicit indicators to assess CCPNM performance; a shortage of permanent staff with sufficient technical expertise; poor coordination among institutions in preparing background materials for the annual negotiation process in a timely manner; insufficient communication among committees and institutions; and a lack of political support to ensure the sustainability of the CCPNM.

It is a fundamental truth in solid compounds that the physical properties follow the symmetry of the crystal structure. Nowhere is the effect of symmetry more pronounced than in the electronic and magnetic properties of materials-even the projection of the bulk crystal symmetry onto different crystal faces is known to have a substantial impact on the surface electronic states. The effect of bulk crystal symmetry on the properties of superconductors is widely appreciated, although its study presents substantial challenges. The effect of a lack of a center of symmetry in a crystal structure, for example, has long been understood to necessitate that the wave function of the collective electron state that gives rise to superconductivity has to be more complex than usual. However, few nonhypothetical materials, if any, have actually been proven to display exotic superconducting properties as a result. We introduce two new superconductors that in addition to having noncentrosymmetric crystal structures also have chiral crystal structures. Because the wave function of electrons in solids is particularly sensitive to the host material's symmetry, crystal structure chirality is expected to have a substantial effect on their superconducting wave functions. Our two experimentally obtained chiral noncentrosymmetric superconducting materials have transition temperatures to superconductivity that are easily experimentally accessible, and our basic property characterization suggests that their superconducting properties may be unusual. We propose that their study may allow for a more in-depth understanding of how chirality influences the properties of superconductors and devices that incorporate them.

Common Challenges Faced by Women of Color in Physics, and Actions Faculty Can Take to Minimize Those Challenges

Women of color are deeply underrepresented in physics. Between 2002 and 2012, only 1% of graduating physics majors were Black women and another 1% were Latinas; only 61 American Indian women total completed degrees in physics in those years (out of 48,000 physics majors). This isolation can lead to additional obstacles that women of color majoring in physics must face above and beyond the challenging material. In this article we draw on qualitative findings to describe common obstacles women of color face. However, departments can take deliberate steps so that underrepresentation need not turn into loneliness and isolation. We describe the characteristics of a department where women of color report that they are thriving. We end with concrete steps physics faculty can take to support women physics majors of color.

Not-for-profit hospitals fight tax-exempt challenges.

Hudson, T

1990-10-20

The message being sent by local tax boards, state agencies, and the Internal Revenue Service is clear: Not-for-profit hospitals will have to justify their tax-exempt status. But complying with this demand can be a costly administrative burden. Just ask the executives who have been through the experience. CEO Richard Anderson, of St. Luke's Hospital, Bethlehem, PA, is luckier than some executives who have faced tax-exempt challenges. He won his hospital's case. But he still faces a yearly battle: The hospital must prove its compliance annually to the county board of assessors. Other executives report similar experiences. Our cover story takes an in-depth look at how administrators faced challenges to their hospital's tax status and what they learned about their relationship with their communities, as well as a complete state and federal legislative outlook for future developments.

While global programs targeting the control or elimination of five of the neglected tropical diseases (NTDs)-lymphatic filariasis, onchocerciasis, soil-transmitted helminthiasis, schistosomiasis and trachoma-are well underway, they still face many operational challenges. Because of the urgency of 2020 program targets, the Bill & Melinda Gates Foundation and the U.S. Agency for International Development devised a novel rapid research response (RRR) framework to engage national programs, researchers, implementers and WHO in a Coalition for Operational Research on NTDs. After 2 years, this effort has succeeded as an important basis for the research response to programmatic challenges facing NTD programs. © The Author 2016.

This paper addresses the problem of tracking and recognizing faces via incremental local sparse representation. First a robust face tracking algorithm is proposed via employing local sparse appearance and covariance pooling method. In the following face recognition stage, with the employment of a novel template update strategy, which combines incremental subspace learning, our recognition algorithm adapts the template to appearance changes and reduces the influence of occlusion and illumination variation. This leads to a robust video-based face tracking and recognition with desirable performance. In the experiments, we test the quality of face recognition in real-world noisy videos on YouTube database, which includes 47 celebrities. Our proposed method produces a high face recognition rate at 95% of all videos. The proposed face tracking and recognition algorithms are also tested on a set of noisy videos under heavy occlusion and illumination variation. The tracking results on challenging benchmark videos demonstrate that the proposed tracking algorithm performs favorably against several state-of-the-art methods. In the case of the challenging dataset in which faces undergo occlusion and illumination variation, and tracking and recognition experiments under significant pose variation on the University of California, San Diego (Honda/UCSD) database, our proposed method also consistently demonstrates a high recognition rate.

Opportunities and challenges for comparative effectiveness research (CER) with Electronic Clinical Data: a perspective from the EDM forum.

2012-07-01

The Electronic Data Methods (EDM) Forum brings together perspectives from the Prospective Outcome Systems using Patient-specific Electronic data to Compare Tests and therapies (PROSPECT) studies, the Scalable Distributed Research Networks, and the Enhanced Registries projects. This paper discusses challenges faced by the research teams as part of their efforts to develop electronic clinical data (ECD) infrastructure to support comparative effectiveness research (CER). The findings reflect a set of opportunities for transdisciplinary learning, and will ideally enhance the transparency and generalizability of CER using ECD. Findings are based on 6 exploratory site visits conducted under naturalistic inquiry in the spring of 2011. Themes, challenges, and innovations were identified in the visit summaries through coding, keyword searches, and review for complex concepts. : The identified overarching challenges and emerging opportunities include: the substantial level of effort to establish and sustain data sharing partnerships; the importance of understanding the strengths and limitations of clinical informatics tools, platforms, and models that have emerged to enable research with ECD; the need for rigorous methods to assess data validity, quality, and context for multisite studies; and, emerging opportunities to achieve meaningful patient and consumer engagement and work collaboratively with multidisciplinary teams. The new infrastructure must evolve to serve a diverse set of potential users and must scale to address a range of CER or patient-centered outcomes research (PCOR) questions. To achieve this aim-to improve the quality, transparency, and reproducibility of CER and PCOR-a high level of collaboration and support is necessary to foster partnership and best practices as part of the EDM Forum.

The Inventory of College Challenges for Ethnic Minority Students (ICCEMS) is a newly developed instrument that assesses challenges faced by ethnic minority college students across a range of cultural, academic, social, and practical domains. The present study tested the ICCEMS among Chinese American students in an attempt to identify its factor structure and assess its psychometric properties. A total of 13 factor domains emerged. The Cronbach's alpha and 1-month test-retest reliability of the subscales and the overall scale supported their reliability. Both criterion and construct validities were also demonstrated. Chinese American college students faced the greatest challenges in terms of unclear career direction and academic demands. 2004 APA

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.

Kothari, M P; Kothari, V

1997-01-01

The healthcare industry in the United States is faced with many strategic challenges, because of the nation's growing culturally diverse population. Growing cultural diversity now calls for better trained medical staff that is capable of handling language, religious and cultural differences. In the rural communities, where cultural diversity is rapidly becoming a demographic fact, small hospitals with limited resources are especially confronted with medical challenges for which they seem to be least prepared. Based on an exploratory research that includes a study of small town hospitals, this paper provides insights into cross-cultural problems facing healthcare professionals in small communities. The paper highlights also the ways in which hospitals are responding to such challenges.

Tolerance to spatial-relational transformations in unfamiliar faces: A further challenge to a configural processing account of identity recognition.

PubMed

Lorenzino, Martina; Caminati, Martina; Caudek, Corrado

2018-05-25

One of the most important questions in face perception research is to understand what information is extracted from a face in order to recognize its identity. Recognition of facial identity has been attributed to a special sensitivity to "configural" information. However, recent studies have challenged the configural account by showing that participants are poor in discriminating variations of metric distances among facial features, especially for familiar as opposed to unfamiliar faces, whereas a configural account predicts the opposite. We aimed to extend these previous results by examining classes of unfamiliar faces with which we have different levels of expertise. We hypothesized an inverse relation between sensitivity to configural information and expertise with a given class of faces, but only for neutral expressions. By first matching perceptual discriminability, we measured tolerance to subtle configural transformations with same-race (SR) versus other-race (OR) faces, and with upright versus upside-down faces. Consistently with our predictions, we found a lower sensitivity to at-threshold configural changes for SR compared to OR faces. We also found that, for our stimuli, the face inversion effect disappeared for neutral but not for emotional faces - a result that can also be attributed to a lower sensitivity to configural transformations for faces presented in a more familiar orientation. The present findings question a purely configural account of face processing and suggest that the role of spatial-relational information in face processing varies according to the functional demands of the task and to the characteristics of the stimuli.

Telephone consultations with general practitioners (GPs) have not been shown to be an effective way to reduce the demandfor face-to face appointments during the surgery hours. This study aims to determine if GP telephone triage can effectively reduce the demandforface-to -face consultations for patients seeking same-day appointments in general practice. We report an interrupted time series, twoyears before and one year after introduction of GP-led telephone triage. Demand for face-to face appointments with a GPwas reduced by 39% (95% CI = 29 to 51%, P < 0.001). more than 92% of the telephone calls lasted less thanfive minutes. The telephone bill increased by 26%. For a substantial proportion of patients seeking same-day appointments telephone consultations were an acceptable alternative service.

A fuel cell stack is disclosed with modified electrolyte matrices for limiting the electrolytic pumping and electrolyte migration along the stack external surfaces. Each of the matrices includes marginal portions at the stack face of substantially greater pore size than that of the central body of the matrix. Consequently, these marginal portions have insufficient electrolyte fill to support pumping or wicking of electrolyte from the center of the stack of the face surfaces in contact with the vertical seals. Various configurations of the marginal portions include a complete perimeter, opposite edge portions corresponding to the air plenums and tab size portions corresponding to the manifold seal locations. These margins will substantially limit the migration of electrolyte to and along the porous manifold seals during operation of the electrochemical cell stack. 6 figs.

2015-05-01

Women in Indian culture have a paradoxical status: on the one hand, goddesses are worshipped for power and prosperity; on the other hand, working women face challenges due to age-old beliefs and sociocultural norms. With 60% of the students enrolled in undergraduate dental education currently being women, there is a need to study the challenges these women are facing and how they tackle them. The aim of this survey study was to assess the barriers women dentists face in career advancement and how successfully they balance the personal, professional, and social aspects of their lives. Questionnaires, consisting of four qualitative and 24 quantitative items, were distributed to 500 women dentists: postgraduate residents and faculty members in dental colleges of Mumbai and Navi Mumbai, as well as private dental practitioners. Of the 500 women, 210 returned the survey, for an overall response rate of 42%. The results showed that 95% of the respondents believed they successfully balance the various spheres of their lives, but the most common challenges they faced continued to be traditional gender bias, dual professional and home responsibilities, and preconceived ideas about women.

Combined effects of inversion and feature removal on N170 responses elicited by faces and car fronts

PubMed Central

Kloth, Nadine; Itier, Roxane J.; Schweinberger, Stefan R.

2014-01-01

The face-sensitive N170 is typically enhanced for inverted compared to upright faces. Itier, Alain, Sedore, and McIntosh (2007) recently suggested that this N170 inversion effect is mainly driven by the eye region which becomes salient when the face configuration is disrupted. Here we tested whether similar effects could be observed with non-face objects that are structurally similar to faces in terms of possessing a homogeneous within-class first-order feature configuration. We presented upright and inverted pictures of intact car fronts, car fronts without lights, and isolated lights, in addition to analogous face conditions. Upright cars elicited substantial N170 responses of similar amplitude to those evoked by upright faces. In strong contrast to face conditions however, the car-elicited N170 was mainly driven by the global shape rather than the presence or absence of lights, and was dramatically reduced for isolated lights. Overall, our data confirm a differential influence of the eye region in upright and inverted faces. Results for car fronts do not suggest similar interactive encoding of eye-like features and configuration for non-face objects, even when these objects possess a similar feature configuration as faces.

2017-01-01

Background Women with disabilities in Zimbabwe face numerous challenges in accessing sexual and reproductive health. Cultural belief still regards them as not sexually active. The government has also failed to promote policies that facilitate access to sexual and reproductive services by women with disabilities. Objectives The reseach objectives were to explore the challenges faced by women with disabilities in accessing sexual and reproductive health in Zimbabwe. Method The data were gathered using in-depth interviews with 23 purposively selected respondents. Thirteen women had physical disabilities, five were visually impaired, three were deaf and two were stammering. The respondents with physical disabilities were using wheelchairs, walking frames, prosthesis, crutches and caliper shoes. The participants’ ages ranged from 18 to 45 years. All interviews were transcribed and translated verbatim into English, and passages were extracted from the transcripts. Key themes and concepts were identified and coded to offer a rich framework for analysis, comparisons and presentation of the data. Results Negative perceptions of health personnel towards people with disabilities, disability-unfriendly infrastructure at health facilities and absence of trained personnel for people with disabilities (sign language) are some of the challenges involved. Conclusion The government, in partnership with other stakeholders, should address challenges faced by women with disabilities when accessing sexual and reproductive health services. Non-government, private hospitals and profit-making organisations should join hands with government in funding health requirements for women with disabilities. PMID:28730062
