2013-04-01

This two hour special workshop was held during the 2012 ASP conference in Tucson. There are a variety of reasons that science education needs to reach out to culturally diverse audiences. Each culture, and each individual community, has its own challenges; each brings special insight to science. What does the research say about engaging these different audiences? How can science educators attract and sustain programs with various cultures? How do the needs of our audiences vary with culture and within communities? Moderators Shupla, Sanlyn, and Peticolas invited a variety of presenters with expertise to share their experiences: Salvador Acevado, David Begay, Michelle Higgins, Bryan Mendez, and Dara Norman. During the first hour, presenters shared a variety of best practices for engaging and supporting culturally diverse audiences; in the second hour, participants and presenters discussed specific programmatic challenges and possible directions.

Military Social Work: Opportunities and Challenges for Social Work Education

PubMed Central

Wooten, Nikki R.

2015-01-01

Military social work is a specialized field of practice spanning the micro-macro continuum and requiring advanced social work knowledge and skills. The complex behavioral health problems and service needs of Iraq and Afghanistan veterans highlight the need for highly trained social work professionals who can provide militarily-relevant and culturally-responsive evidence-informed services. Responding to the military behavioral health workforce and service needs of recently returned veterans presents both opportunities and challenges for military social work education. This article discusses the rationale for a military social work specialization, the need for military social work education, and opportunities and challenges for social work education. An integrated model of intellectual capital is proposed to guide strategic planning for future military social work education. PMID:26089628

Occupational asthma due to manual metal-arc welding of special stainless steels.

PubMed

Hannu, T; Piipari, R; Kasurinen, H; Keskinen, H; Tuppurainen, M; Tuomi, T

2005-10-01

Occupational asthma (OA) can be induced by fumes of manual metal-arc welding on stainless steel. In recent years, the use of special stainless steels (SSS) with high chromium content has increased. This study presents two cases of OA caused by manual metal-arc welding on SSS. In both cases, the diagnosis of OA was based on respiratory symptoms, occupational exposure and positive findings in the specific challenge tests. In the first case, a 46-yr-old welder had experienced severe dyspnoea while welding SSS (SMO steel), but not in other situations. Challenge tests with both mild steel and stainless steel using a common electrode were negative. Welding SSS with a special electrode caused a delayed 37% drop in forced expiratory volume in one second (FEV1). In the second case, a 34-yr-old male had started to experience dyspnoea during the past few years, while welding especially SSS (Duplex steel). The workplace peak expiratory flow monitoring was suggestive of OA. Challenge tests with both mild steel and stainless steel using a common electrode did not cause bronchial obstruction. Welding SSS with a special electrode caused a delayed 31% drop in FEV1. In conclusion, exposure to manual metal-arc welding fumes of special stainless steel should be considered as a new cause of occupational asthma.

Kluge, Eike-Henner W

2011-01-01

eHealth is a cost-effective and efficient way of providing health care to patients who would otherwise be excluded or underserviced. However, eHealth also presents a series of ethical and legal challenges which, if not met before its implementation, can undermine its success. Among other things, privacy, consent and liability are implicated, as are changes in the health care professional-patient relationship and in the role of health informatics professionals. Legacy systems and interoperability present further challenges, and outsourcing may pose special problems. This paper highlights some of these issues and outlines their implications.

Providing health services for children with special health care needs on out-of-state field trips.

PubMed

Erwin, Karen; Clark, Saudi; Mercer, Sharon Eli

2014-03-01

An increasing number of children attend school with special health care needs. Title II of the Americans with Disabilities Act (ADA) requires all school-sponsored activities to be easily accessible to all students. School-sponsored field trips enhance students' education, and students who require health services may not be excluded. For students with special health care needs, fully participating in the field trip experience presents unique challenges. These challenges are further complicated by out-of-state field trips due to variances in nurse practice acts, variances in delegation regulations, and most recently, state-by-state participation or nonparticipation in the Nurse Licensure Compact. Review of state laws, regulations, and nursing scope of practice for school health services is critical when planning and problem solving for students requiring health services on out-of-state field trips.

Challenges to reestablishment of free-ranging populations of black-footed ferrets

USGS Publications Warehouse

Biggins, D.E.; Godbey, J.L.

2003-01-01

The black-footed ferret (Mustela nigripes) of North America is critically endangered due in part to its extreme specialization on formerly stable and abundant prairie dogs (Cynomys). Its close relative, the Siberian polecat (M. eversmannii) seems to have been subjected to a varying environment that was not conducive to specialization. One source of environmental variation in Asian steppes was plague (caused by Yersina pestis), which was absent from North America. Introduction of plague to North America presents serious challenges to ferret recovery. Partial solutions to other biological and political problems have been found, resulting in improved production in captivity, increased survival post-release, and thriving populations in plague-free South Dakota.

Magnetic Resonance Microscopy of the Lung

NASA Astrophysics Data System (ADS)

Johnson, G. Allan

1999-11-01

The lung presents both challenges and opportunities for study by magnetic resonance imaging (MRI). The technical challenges arise from respiratory and cardiac motion, limited signal from the tissues, and unique physical structure of the lung. These challenges are heightened in magnetic resonance microscopy (MRM) where the spatial resolution may be up to a million times higher than that of conventional MRI. The development of successful techniques for MRM of the lung present enormous opportunities for basic studies of lung structure and function, toxicology, environmental stress, and drug discovery by permitting investigators to study this most essential organ nondestructively in the live animal. Over the last 15 years, scientists at the Duke Center for In Vivo Microscopy have developed techniques for MRM in the live animal through an interdisciplinary program of biology, physics, chemistry, electrical engineering, and computer science. This talk will focus on the development of specialized radiofrequency coils for lung imaging, projection encoding methods to limit susceptibility losses, specialized support structures to control and monitor physiologic motion, and the most recent development of hyperpolarized gas imaging with ^3He and ^129Xe.

Tropical cyclones (TCs) are among the most destructive natural hazards on Earth. The ocean can have dramatic responses to TCs and further imposes significant feedbacks to the atmosphere. A comprehensive understanding of the ocean-TC interaction is a challenging hindrance for improving the simulation and prediction of TCs and therefore avoidance of human and economic losses. A special section of JGR-Oceans was thus organized, in order to have a broad summary of latest progress in ocean-TC interactions. This introduction presents a brief overview of the contributions found in this collection. We hope it can also shed light on recent advance and future challenges in the studies on the oceanic responses and feedbacks to TCs.

2015-01-01

Contrary to many historical views, recent evidence suggest that species-level behavioral and brain asymmetries are evident in nonhuman species. Here, we briefly present evidence of behavioral, perceptual, cognitive, functional, and neuroanatomical asymmetries in nonhuman primates. In addition, we describe two historical accounts of the evolutionary origins of hemispheric specialization and present data from nonhuman primates that address these specific theories. Specifically, we first discuss the evidence of that genes play specific roles in determining left–right differences in anatomical and functional asymmetries in primates. We next consider and present data on the hypothesis that hemispheric specialization evolved as a by-product of increasing brain size relative to the size of the corpus callosum in different primate species. Lastly, we discuss some of the challenges in the study of hemispheric specialization in primates and offer some suggestions on how to advance the field. PMID:26426409

Testing Scientific Software: A Systematic Literature Review.

PubMed

Kanewala, Upulee; Bieman, James M

2014-10-01

Scientific software plays an important role in critical decision making, for example making weather predictions based on climate models, and computation of evidence for research publications. Recently, scientists have had to retract publications due to errors caused by software faults. Systematic testing can identify such faults in code. This study aims to identify specific challenges, proposed solutions, and unsolved problems faced when testing scientific software. We conducted a systematic literature survey to identify and analyze relevant literature. We identified 62 studies that provided relevant information about testing scientific software. We found that challenges faced when testing scientific software fall into two main categories: (1) testing challenges that occur due to characteristics of scientific software such as oracle problems and (2) testing challenges that occur due to cultural differences between scientists and the software engineering community such as viewing the code and the model that it implements as inseparable entities. In addition, we identified methods to potentially overcome these challenges and their limitations. Finally we describe unsolved challenges and how software engineering researchers and practitioners can help to overcome them. Scientific software presents special challenges for testing. Specifically, cultural differences between scientist developers and software engineers, along with the characteristics of the scientific software make testing more difficult. Existing techniques such as code clone detection can help to improve the testing process. Software engineers should consider special challenges posed by scientific software such as oracle problems when developing testing techniques.

Translating human biology (introduction to special issue).

Brewis, Alexandra A; Mckenna, James J

2015-01-01

Introducing a special issue on "Translating Human Biology," we pose two basic questions: Is human biology addressing the most critical challenges facing our species? How can the processes of translating our science be improved and innovated? We analyze articles published in American Journal of Human Biology from 2004-2013, and find there is very little human biological consideration of issues related to most of the core human challenges such as water, energy, environmental degradation, or conflict. There is some focus on disease, and considerable focus on food/nutrition. We then introduce this special volume with reference to the following articles that provide exemplars for the process of how translation and concern for broader context and impacts can be integrated into research. Human biology has significant unmet potential to engage more fully in translation for the public good, through consideration of the topics we focus on, the processes of doing our science, and the way we present our domain expertise. © 2014 Wiley Periodicals, Inc.

Marine Environmental Emergencies in the North Pacific Ocean: Lessons Learned from Recent Oil Spills.

PubMed

Yim, Un Hyuk; Short, Jeffrey

2017-07-01

Increasing marine vessel traffic, and oil and gas exploration and development throughout the North Pacific basin brings increasing risks of oil spills. Recognizing the serious challenges presented to response authorities, this Special Issue was organized by the North Pacific Marine Science Organization to provide an introduction to the current state of scientific understanding regarding the environmental effects of oil spills. Because interactions of spilled oils with biota and their habitats are complex, the most serious environmental damages from these spills are not necessarily those of greatest immediate concern by the public. Our overarching goal for this Special Issue is to provide an efficient introduction to the most important ways that oil spills can harm biota, habitats, and ecosystems through invited, targeted mini-reviews augmented by original research articles. We provide a brief background on the challenges posed by large oil spills to response authorities, summarize findings from the articles published in this Special Issue, and highlight some key research needs.

Challenges to reestablishment of free-ranging populations of black-footed ferrets

USGS Publications Warehouse

Biggins, D.E.; Godbey, J.L.

2003-01-01

The black-footed ferret (Mustela nigripes) of North America is critically endangered due in part to its extreme specialization on formerly stable and abundant prairie dogs (Cynomys). Its close relative, the Siberian polecat (M. eversmannii) seems to have been subjected to a varying environment that was not conducive to specialization. One source of environmental variation in Asian steppes was plague (caused by Yersina pestis), which was absent from North America. Introduction of plague to North America presents serious challenges to ferret recovery. Partial solutions to other biological and political problems have been found, resulting in improved production in captivity, increased survival post-release, and thriving populations in plague-free South Dakota. ?? 2003 Acade??mie des sciences.

Testing Scientific Software: A Systematic Literature Review

PubMed Central

Kanewala, Upulee; Bieman, James M.

2014-01-01

Context Scientific software plays an important role in critical decision making, for example making weather predictions based on climate models, and computation of evidence for research publications. Recently, scientists have had to retract publications due to errors caused by software faults. Systematic testing can identify such faults in code. Objective This study aims to identify specific challenges, proposed solutions, and unsolved problems faced when testing scientific software. Method We conducted a systematic literature survey to identify and analyze relevant literature. We identified 62 studies that provided relevant information about testing scientific software. Results We found that challenges faced when testing scientific software fall into two main categories: (1) testing challenges that occur due to characteristics of scientific software such as oracle problems and (2) testing challenges that occur due to cultural differences between scientists and the software engineering community such as viewing the code and the model that it implements as inseparable entities. In addition, we identified methods to potentially overcome these challenges and their limitations. Finally we describe unsolved challenges and how software engineering researchers and practitioners can help to overcome them. Conclusions Scientific software presents special challenges for testing. Specifically, cultural differences between scientist developers and software engineers, along with the characteristics of the scientific software make testing more difficult. Existing techniques such as code clone detection can help to improve the testing process. Software engineers should consider special challenges posed by scientific software such as oracle problems when developing testing techniques. PMID:25125798

The dire need for primary care specialization in India: Concerns and challenges.

PubMed

Faizi, Nafis; Khalique, Najam; Ahmad, Anees; Shah, Mohammad Salman

2016-01-01

Primary health care is an evidence-based priority, but it is still inadequately supported in many countries. Ironically, on one hand, India is a popular destination for medical tourism due to the affordability of high quality of health care and, on the other hand, ill health and health care are the main reasons for becoming poor through medical poverty traps. Surprisingly, this is despite the fact that India was committed to 'Health for All by 2000' in the past, and is committed to 'Universal Health Coverage' by 2022! Clearly, these commitments are destined to fail unless something is done to improve the present state of affairs. This study argues for the need to develop primary care as a specialization in India as a remedial measure to reform its health care in order to truly commit to the commitments. Three critical issues for this specialization are discussed in this review: (1) The dynamic and distinct nature of primary care as opposed to other medical specializations, (2) the intersection of primary care and public health which can be facilitated by such a specialization, and (3) research in primary care including the development of screening and referral tools for early diagnosis of cancers, researches for evidence-based interventions via health programs, and primary care epidemiology. Despite the potential challenges and difficulties, India is a country in dire need for primary care specialization. India's experience in providing low-cost and high quality healthcare for medical tourism presages a more cost-effective and efficient primary care with due attention and specialization.

Functional perspectives on emotion, behavior, and cognition.

PubMed

Lench, Heather C; Darbor, Kathleen E; Berg, Logan A

2013-12-01

This Editorial reviews the challenges and advantages posed by a functional perspective on the relationships among emotion, behavior, and cognition. We identify the core themes among the articles published as part of this Special Issue. The articles generally address two important questions: (1) are emotions functional and what is their impact on behavioral and cognitive processes, and (2) how do the interactions among emotion, cognition, and behavior play out in particular situations that present adaptive challenges? We also identify two core questions raised by the articles included in this Special Issue. Future research must address the extent to which emotions are best represented as discrete emotional constructs (e.g., anger, sadness, fear) versus emotions that vary along dimensions, such as valence and arousal. Functional perspectives would also be facilitated by identification of situations or environments that are likely to elicit particular emotions and reactions.

A special challenge has been presented to academic medical practices by the new healthcare environment. While increased competition for patients and resources affects all medical groups, it is the academic practices who are responsible for training the physicians of tomorrow. Not only must they sharpen their students' awareness of the new environment and teach them to incorporate effective management strategies into their practices, but they must set an example in effective management as well. The basic concepts of competitive marketing strategy, along with helpful exhibits, are presented here, and strategies for effectively maximizing position are discussed from the viewpoints of product mix, process market, and financing.

Hattem, M V; Paterson, L; Woollett, J

2008-08-20

65 surveys were completed in 2002 to assess the current distribution of special status amphibians at the Lawrence Livermore National Laboratory's (LLNL) Livermore Site and Site 300. Combined with historical information from previous years, the information presented herein illustrates the dynamic and probable risk that amphibian populations face at both sites. The Livermore Site is developed and in stark contrast to the mostly undeveloped Site 300. Yet both sites have significant issues threatening the long-term sustainability of their respective amphibian populations. Livermore Site amphibians are presented with a suite of challenges inherent of urban interfaces, most predictably the bullfrog (Ranamore » catesbeiana), while Site 300's erosion issues and periodic feral pig (Sus scrofa) infestations reduce and threaten populations. The long-term sustainability of LLNL's special status amphibians will require active management and resource commitment to maintain and restore amphibian habitat at both sites.« less

Ennis, Catherine D

This commentary uses the lens of curricular implementation to consider issues and opportunities afforded by the papers in this special edition. While it is interesting to envision innovative approaches to physical education, actually implementing changes in the complex institutional school environment is exceptionally challenging. These authors have done an excellent job presenting viable solutions and fore grounding challenges. Yet, without a concerted effort to invite teachers to engage with us in this process, our implementation initiatives may not enhance the meaningful and educative process that these scholars envision for physical education.

Introduction to the Special Issue: Interventions to Reduce Challenging Behavior Among Individuals With Autism Spectrum Disorder.

PubMed

Davis, Tonya N; Rispoli, Mandy

2018-05-01

The prevalence of autism spectrum disorder (ASD) is on the rise. In addition to the social communication skill deficits and restrictive repetitive behaviors and interests, many individuals with ASD engage in challenging behavior. Challenging behavior is associated with a multitude of negative outcomes. Challenging behavior may cause harm to the individual with ASD as well as limit opportunities for educational, vocational, and social participation and development. In addition, caregivers experience high stress and low quality of mental health. As a result, challenging behavior warrants intervention that is specifically tailored to the unique characteristics of individuals with ASD. The purpose of this Special Issue is to showcase recent research in the treatment of challenging behavior for individuals with ASD. This two-part Special Issue contains 12 studies that range from systematic and quality reviews of the intervention literature, to innovative treatment approaches, to studies that develop and evaluate treatments for restrictive and repetitive behaviors and interests.

1999-06-01

Molecular biology laboratories frequently face the challenge of aligning small overlapping DNA sequences derived from a long DNA segment. Here, we present a short program that can be used to adapt Excel spreadsheets as a tool for aligning DNA sequences, regardless of their orientation. The program runs on any Windows or Macintosh operating system computer with Excel 97 or Excel 98. The program is available for use as an Excel file, which can be downloaded from the BioTechniques Web site. Upon execution, the program opens a specially designed customized workbook and is capable of identifying overlapping regions between two sequence fragments and displaying the sequence alignment. It also performs a number of specialized functions such as recognition of restriction enzyme cutting sites and CpG island mapping without costly specialized software.

What influences patient decision-making in amyotrophic lateral sclerosis multidisciplinary care? A study of patient perspectives.

PubMed

Hogden, Anne; Greenfield, David; Nugus, Peter; Kiernan, Matthew C

2012-01-01

Patients with amyotrophic lateral sclerosis (ALS) are required to make decisions concerning quality of life and symptom management over the course of their disease. Clinicians perceive that patients' ability to engage in timely decision-making is extremely challenging. However, we lack patient perspectives on this issue. This study aimed to explore patient experiences of ALS, and to identify factors influencing their decision-making in the specialized multidisciplinary care of ALS. An exploratory study was conducted. Fourteen patients from two specialized ALS multidisciplinary clinics participated in semistructured interviews that were audio recorded and transcribed. Data were analyzed for emergent themes. Decision-making was influenced by three levels of factors, ie, structural, interactional, and personal. The structural factor was the decision-making environment of specialized multidisciplinary ALS clinics, which supported decision-making by providing patients with disease-specific information and specialized care planning. Interactional factors were the patient experiences of ALS, including patients' reaction to the diagnosis, response to deterioration, and engagement with the multidisciplinary ALS team. Personal factors were patients' personal philosophies, including their outlook on life, perceptions of control, and planning for the future. Patient approaches to decision-making reflected a focus on the present, rather than anticipating future progression of the disease and potential care needs. Decision-making for symptom management and quality of life in ALS care is enhanced when the patient's personal philosophy is supported by collaborative relationships between the patient and the multidisciplinary ALS team. Patients valued the support provided by the multidisciplinary team; however, their focus on living in the present diverged from the efforts of health professionals to prepare patients and their carers for the future. The challenge facing health professionals is how best to engage each patient in decision-making for their future needs, to bridge this gap.

1999-01-30

A PUBLIC HEALTH CHALLENGE: Cerebral vascular events are the third most frequent cause of death in the adult population and the number one cause of disabilities, a public health challenge both in terms of health care service and health care expenditures. Structured health care facilities, particularly specialized hospital units, can lower mortality, limit residual disability and reduce the need for long-term institutionalization. Specialized research and teaching units are paradigmatic of the impact of health care organization. The limited number of such specialized units in France raises important ethical considerations about effective access to health care. Functioning units could be a useful criteria for auditing quality of hospital facilities.

Geriatric Medicine is concerned chiefly with the care of frail elderly people, especially when they become ill. Physicians face special challenges in dealing with such patients, who tend to have multiple interacting medical and social problems, impaired function, altered pharmacokinetics and pharmacodynamics, atypical disease presentations and to be affected by polypharmacy. The joy of geriatrics is in systematically meeting each of these challenges, but the techniques that geriatricians use to do so must not be kept secret. More must be done to encourage all physicians to use these techniques in caring for frail elderly people who are ill.

An ethics of body scanners: requirements and future challenges from an ethical point of view

NASA Astrophysics Data System (ADS)

Rampp, Benjamin; Wolkenstein, Andreas F. X.; Ammicht Quinn, Regina

2011-05-01

At the moment, body scanners based on terahertz and millimeter-wave technologies are implemented at airports around the world. Thus, challenges of acceptance and acceptability become pressing. In this context, we present the results of an ethical research project on the development and implementation of body scanners. We will show which requirements concerning the system, its developers, and its users should be met in order that the scanners can be acceptable from an ethical point of view. These requirements involve, among others, questions of privacy, health, data protection, and security processes. A special ethical challenge for body scanners, however, still remains: Automatic anonymization processes are based on the assumption of "normal" bodies. Certain groups of persons with "deviant bodies" (e.g. persons with hidden disabilities, persons with aberrant sex characteristics, etc.) are affected in a special way: Their deviation from the standard (for instance their disability) is socially hidden, but eventually exposed by body scanners, even (and even more) if the produced pictures are anonymized. Here, we address the question how the possible discrimination against and exclusion of people with "deviant bodies" could be mitigated or prevented.

Challenges and Developments in the Assessment of (Mal)adaptive Personality and Pathological States in Older Adults.

2018-04-01

Since older adults often show an atypical presentation of (mal)adaptive personality traits and pathological states, the articles in this special issue will concisely discuss some perennial issues in clinical assessment in older adults and thus outline the main challenges this domain faces. By bringing empirical work and meta-analytic studies from leading scholars in the field of geropsychology, the articles will also address these challenges by reporting the latest developments in the field. This way, we hope to reshape the way clinicians and researchers assess (mal)adaptive personality and pathological states in older adults into a more reliable and valid assessment method that integrates the specific biopsychosocial context of older age.

Public involvement in health priority setting: future challenges for policy, research and society.

Hunter, David James; Kieslich, Katharina; Littlejohns, Peter; Staniszewska, Sophie; Tumilty, Emma; Weale, Albert; Williams, Iestyn

2016-08-15

Purpose - The purpose of this paper is to reflect on the findings of this special issue and discusses the future challenges for policy, research and society. The findings suggest that challenges emerge as a result of legitimacy deficits of both consensus and contestatory modes of public involvement in health priority setting. Design/methodology/approach - The paper draws on the discussions and findings presented in this special issue. It seeks to bring the country experiences and case studies together to draw conclusions for policy, research and society. Findings - At least two recurring themes emerge. An underlying theme is the importance, but also the challenge, of establishing legitimacy in health priority setting. The country experiences suggest that we understand very little about the conditions under which representative, or authentic, participation generates legitimacy and under which it will be regarded as insufficient. A second observation is that public participation takes a variety of forms that depend on the opportunity structures in a given national context. Given this variety the conceptualization of public participation needs to be expanded to account for the many forms of public participation. Originality/value - The paper concludes that the challenges of public involvement are closely linked to the question of how legitimate processes and decisions can be generated in priority setting. This suggests that future research must focus more narrowly on conditions under which legitimacy are generated in order to expand the understanding of public involvement in health prioritization.

Saida, Fakhri B; Chen, Xiaoru; Tran, Kiet; Dou, Chao; Yuan, Chong

2015-03-01

25-Hydroxyvitamin D [25(OH)D], the predominant circulating form of vitamin D, is an accurate indicator of the general vitamin D status of an individual. Because vitamin D deficiencies have been linked to several pathologies (including osteoporosis and rickets), accurate monitoring of 25(OH)D levels is becoming increasingly important in clinical settings. Current 25(OH)D assays are either chromatographic or immunoassay-based assays. These assays include HPLC, liquid chromatography-tandem mass spectrometry (LC-MS/MS), enzyme-immunosorbent, immunochemiluminescence, immunofluorescence and radioimmunoassay. All these assays use heterogeneous formats that require phase separation and special instrumentations. In this article, we present an overview of these assays and introduce the first homogeneous assay of 25(OH)D for use on general chemistry analyzers. A special emphasis is put on the unique challenges posed by the 25(OH)D analyte. These challenges include a low detection limit, the dissociation of the analyte from its serum transporter and the inactivation of various binding proteins without phase separation steps.

[Re-organization of internal medicine wing in hospitals: a last-ditch effort or the beginning of reform?].

PubMed

Sharabi, Yehonatan

2014-01-01

Over the last decade numerous publications have dealt with ongoing changes in the traditional practice of internal medicine. In general, in-hospital medicine has evolved into ambulatory or specialized care. In this volume of Harefuah, Yinon et al. discuss trends at Shaare-Zedek Medical Center, focusing on the challenge of attracting residents to general internal medicine. Their model addresses local problems, but they have laid the groundwork for a more radical change. They present an evolutionary process that would transform hospital practice to become both more patient-centered and integrative, with an interdisciplinary team that translates the strengths of in-hospital (in- and out-patient care) vs. ambulatory or over-specialized care. Such reform should also include changes in clinical medical education, coupled with research and academic activities that can only take place in hospitals. The health care system is waiting for the next academic medical center that will take the lead in accepting this challenge and spearhead much needed reform.

Nature-based solutions for resilient landscapes and cities.

2017-12-04

Nature-based solutions (NBS) are increasingly applied to guide the design of resilient landscapes and cities to enable them to reach economic development goals with beneficial outcomes for the environment and society. The NBS concept is closely related to other concepts including sustainability, resilience, ecosystem services, coupled human and environment, and green (blue) infrastructure; however, NBS represent a more efficient and cost-effective approach to development than traditional approaches. The European Commission is actively engaged in investing in NBS as a driver in developing ecosystem services-based approaches throughout Europe and the world. The pool of knowledge and expertise presented in this Special Issue of Environmental Research highlights the applications of NBS as 'living' and adaptable tools to boost the capacity of landscapes and cities to face today's critical environmental, economic and societal challenges. Based on the literature and papers of this Special Issue, we propose five specific challenges for the future of NBS. Copyright © 2017 Elsevier Inc. All rights reserved.

Special populations: care of the critically ill and injured during pandemics and disasters: CHEST consensus statement.

PubMed

Dries, David; Reed, Mary Jane; Kissoon, Niranjan; Christian, Michael D; Dichter, Jeffrey R; Devereaux, Asha V; Upperman, Jeffrey S

2014-10-01

Past disasters have highlighted the need to prepare for subsets of critically ill, medically fragile patients. These special patient populations require focused disaster planning that will address their medical needs throughout the event to prevent clinical deterioration. The suggestions in this article are important for all who are involved in large-scale disasters or pandemics with multiple critically ill or injured patients, including frontline clinicians, hospital administrators, and public health or government officials. Key questions regarding the care of critically ill or injured special populations during disasters or pandemics were identified, and a systematic literature review (1985-2013) was performed. No studies of sufficient quality were identified. Therefore, the panel developed expert opinion-based suggestions using a modified Delphi process. The panel did not include pediatrics as a separate special population because pediatrics issues are embedded in each consensus document. Fourteen suggestions were formulated regarding the care of critically ill and injured patients from special populations during pandemics and disasters. The suggestions cover the following areas: defining special populations for mass critical care, special population planning, planning for access to regionalized service for special populations, triage and resource allocation of special populations, therapeutic considerations, and crisis standards of care for special populations. Chronically ill, technologically dependent, and complex critically ill patients present a unique challenge to preparing and implementing mass critical care. There are, however, unique opportunities to engage patients, primary physicians, advocacy groups, and professional organizations to lessen the impact of disaster on these special populations.

Thomas, Marcus; Schwartz, Russell

2017-01-01

Molecular self-assembly is the dominant form of chemical reaction in living systems, yet efforts at systems biology modeling are only beginning to appreciate the need for and challenges to accurate quantitative modeling of self-assembly. Self-assembly reactions are essential to nearly every important process in cell and molecular biology and handling them is thus a necessary step in building comprehensive models of complex cellular systems. They present exceptional challenges, however, to standard methods for simulating complex systems. While the general systems biology world is just beginning to deal with these challenges, there is an extensive literature dealing with them for more specialized self-assembly modeling. This review will examine the challenges of self-assembly modeling, nascent efforts to deal with these challenges in the systems modeling community, and some of the solutions offered in prior work on self-assembly specifically. The review concludes with some consideration of the likely role of self-assembly in the future of complex biological system models more generally. PMID:28535149

Resch-Genger, Ute; Gorris, Hans H

2017-10-01

Lanthanide-doped photon-upconversion nanoparticles (UCNPs) have been the focus of many research activities in materials and life sciences in the last 15 years because of their potential to convert light between different spectral regions and their unique photophysical properties. To fully exploit the application potential of these fascinating nanomaterials, a number of challenges have to be overcome, such as the low brightness, particularly of small UCNPs, and the reliable quantification of the excitation-power-density-dependent upconversion luminescence. In this series of critical reviews, recent developments in the design, synthesis, optical-spectroscopic characterization, and application of UCNPs are presented with special focus on bioanalysis and the life sciences. Here we guide the reader from the synthesis of UCNPs to different concepts to enhance their luminescence, including the required optical-spectroscopic assessment to quantify material performance; surface modification strategies and bioanalytical applications as well as selected examples of the use of UCNPs as reporters in different assay formats are addressed in part II. Future trends and challenges in the field of upconversion are discussed with special emphasis on UCNP synthesis and material characterization, particularly quantitative luminescence studies. Graphical Abstract Both synthesis and spectroscopy as well bioanalytical applications of UCNPs are driven and supported by COST Action CM1403 "The European Upconversion Network".

2016-01-01

The present article introduces a special issue of the American Annals of the Deaf. Students who are d/Deaf or hard of hearing and come from homes where a language other than English or American Sign Language is used constitute 19.4%-35.0% of the U.S. d/Dhh population (Gallaudet Research Institute, 2013). The authors propose moving beyond the standardized use of the designation English Language Learners to embrace terminology encompassing these learners as diverse and rich in language: d/Dhh Multilingual Learners (DMLs). The authors present (a) a discussion of terminology, (b) an overview of available demographic data, (c) a synopsis of the special issue, (d) themes across three case study vignettes, and (e) overall recommendations to advance curriculum design and pedagogy for DMLs. Questions are posed challenging researchers and practitioners to investigate theory, research, and pedagogy that can enhance practice with DMLs and their families.

Active contour based segmentation of resected livers in CT images

Oelmann, Simon; Oyarzun Laura, Cristina; Drechsler, Klaus; Wesarg, Stefan

2015-03-01

The majority of state of the art segmentation algorithms are able to give proper results in healthy organs but not in pathological ones. However, many clinical applications require an accurate segmentation of pathological organs. The determination of the target boundaries for radiotherapy or liver volumetry calculations are examples of this. Volumetry measurements are of special interest after tumor resection for follow up of liver regrow. The segmentation of resected livers presents additional challenges that were not addressed by state of the art algorithms. This paper presents a snakes based algorithm specially developed for the segmentation of resected livers. The algorithm is enhanced with a novel dynamic smoothing technique that allows the active contour to propagate with different speeds depending on the intensities visible in its neighborhood. The algorithm is evaluated in 6 clinical CT images as well as 18 artificial datasets generated from additional clinical CT images.

Rupp, Richard E; Rosenthal, Susan L

2003-10-01

Sexually active teens are at significant risk from sexually transmitted infections and girls and women bear the greatest burden of these infections. New methods, such as vaginal microbicides, would provide female controlled options. Microbicides are currently in development and thus it is timely to discuss the progress made and factors that may influence acceptability for teens. Microbicide development presents many challenges, and several different potential mechanisms of action are being explored. There is interest in these products from women and men, and specific preferences are being investigated. Adolescents, due to reproductive system immaturity, developing cognitive abilities and the psychosocial context of their relationships, present a special set of challenges in efforts to foster microbicide use. Vaginal microbicides are on the horizon. Further study into teen issues is required to develop successful strategies for marketing and encouraging adolescent use of microbicides.

Carrier, Felix; Banayan, David; Boley, Randy; Karnik, Niranjan

2017-05-01

As the classification of mental disorders advances towards a disease model as promoted by the National Institute of Mental Health (NIMH) Research Domain Criteria (RDoC), there is hope that a more thorough neurobiological understanding of mental illness may allow clinicians and researchers to determine treatment efficacy with less diagnostic variability. This paradigm shift has presented a variety of ethical issues to be considered in the development of psychiatric drugs. These challenges are not limited to informed consent practices, industry funding, and placebo use. The consideration for alternative research models and quality of research design also present ethical challenges in the development of psychiatric drugs. The imperatives to create valid and sound research that justify the human time, cost, risk and use of limited resources must also be considered. Clinical innovation, and consideration for special populations are also important aspects to take into account. Based on the breadth of these ethical concerns, it is particularly important that scientific questions regarding the development of psychiatric drugs be answered collaboratively by a variety of stakeholders. As the field expands, new ethical considerations will be raised with increased focus on genetic markers, personalized medicine, patient-centered outcomes research, and tension over funding. We suggest that innovation in trial design is necessary to better reflect practices in clinical settings and that there must be an emphasized focus on expanding the transparency of consent processes, regard for suicidality, and care in working with special populations to support the goal of developing sound psychiatric drug therapies.

Referral decisions of teachers and school psychologists for twice-exceptional students

NASA Astrophysics Data System (ADS)

Hoffman, Jennifer Marie

The accurate and timely referral and identification of twice-exceptional students remains a challenge. In a statewide study, the referral decisions for both special education and gifted programming evaluations made by four participant groups (i.e., general education teachers, special education teachers, gifted education teachers, and school psychologists) were compared. Participants were randomly assigned to read one of three identically described students in a vignette that differed only in the presence of a diagnostic label--- autism spectrum disorder (ASD), specific learning disability (SLD), or no diagnostic label. In all, special education teachers made the most special education referrals, while gifted education teachers made the most gifted programming referrals, both regardless of the diagnostic label present. The students with diagnostic labels were recommended for special education referrals significantly more than for gifted programming, while this difference was not evident in the no diagnostic label condition. Moreover, the student with the ASD label was the most likely to be referred for evaluations for both special education and gifted programming out of all three vignette conditions. Overall findings indicated the importance of considering the referral source as well as how the presence of a diagnostic label might influence educational referral decisions, particularly in how this might influence overall multidisciplinary team decisions for these unique learners.

Selective identification of specialized pro-resolving lipid mediators from their biosynthetic double di-oxygenation isomers.

PubMed

Hansen, Trond V; Dalli, Jesmond; Serhan, Charles N

The n-3 polyunsaturated fatty acids are substrates for lipoxygenases and cyclooxygenases. During inflammatory processes, these enzymes form several distinct families of oxygenated polyunsaturated fatty acids coined specialized pro-resolving lipid mediators. Structural elucidation of these natural products using LC-MS/MS based metabololipidomics with the pico- to nanogram amounts of biosynthetic material available have been performed. The specialized pro-resolving lipid mediators display stereospecific and potent anti-inflammatory and pro-resolving actions. Most often the different families among these mediators are chemically characterized by two or three chiral, secondary alcohols, separated by either an E,E,Z -triene or an E,Z,E,E -tetraenemoiety. The lipoxygenases also form other oxygenated polyunsaturated natural products, coined double di-oxygenation products, that are constitutional isomers of the protectin and maresin families of specialized pro-resolving lipid mediators. Very often these products exhibit similar chromatographic properties and mass spectrometrical fragment ions as the pro-resolving mediators. In addition, the double di-oxygenation products are sometimes formed in larger amounts than the specialized pro-resolving lipid mediators. Thus, it is not always possible to distinguish between the specialized pro-resolving mediators and their double di-oxygenation isomers in biological systems, using LC/MS-based techniques. Herein, a convenient and easy-to-use protocol to meet this challenge is presented.

Coping with challenging behaviours of children with autism: effectiveness of brief training workshop for frontline staff in special education settings.

PubMed

Ling, C Y M; Mak, W W S

2012-03-01

The present study examined the effectiveness of three staff training elements: psychoeducation (PE) on autism, introduction of functional behavioural analysis (FBA) and emotional management (EM), on the reaction of challenging behaviours for frontline staff towards children with autism in Hong Kong special education settings. A sample of 311 frontline staff in educational settings was recruited to one of the three conditions: control, PE-FBA and PE-FBA-EM groups. A total of 175 participants completed all three sets of questionnaires during pre-training, immediate post-training and 1-month follow-up. Findings showed that the one-session staff training workshop increased staff knowledge of autism and perceived efficacy but decrease helping behavioural intention. In spite of the limited effectiveness of a one-session staff training workshop, continued staff training is still necessary for the improvement of service quality. Further exploration on how to change emotion response of staff is important. © 2011 The Authors. Journal of Intellectual Disability Research © 2011 Blackwell Publishing Ltd.

Space Radiation and the Challenges Towards Effective Shielding Solutions

NASA Technical Reports Server (NTRS)

Barghouty, Abdulnasser

2014-01-01

The hazards of space radiation and their effective mitigation strategies continue to pose special science and technology challenges to NASA. It is widely accepted now that shielding space vehicles and structures will have to rely on new and innovative materials since aluminum, like all high Z materials, are poor shields against the particulate and highly ionizing nature of space radiation. Shielding solutions, motivated and constrained by power and mass limitations, couple this realization with "multifunctionality," both in design concept as well as in material function and composition. Materials endowed with effective shielding properties as well as with some degree of multi-functionality may be the kernel of the so-called "radiation-smart" structures and designs. This talk will present some of the challenges and potential mitigation ideas towards the realization of such structures and designs.

Guthrie, Robert; Westaway, Jennifer; Goldacre, Lisa

2009-04-01

The objective of this paper is to review the available workers compensation and occupational health and safety data and the legal framework in relation to the agricultural industry to explore whether any factors highlight the need to pay special attention to the particular circumstances of those engaged in the industry. This paper explores some of the special features of the agricultural industry, looking first at agricultural worker fatalities and injuries as a matter of ongoing concern for all participants in this industry, government, as well as occupational health and workers compensation authorities. The paper analyses how occupational health and workers compensation laws may have special application to this industry. Finally, the paper considers some workers compensation provisions that have particular application to the agricultural industry. Our survey of the available data and literature leads to the conclusion that the dangerous nature of agricultural work and the special legal and economic framework in which that work is undertaken identify the agricultural industry as presenting Australian Governments and specialist authorities with particular challenges in relation to improving workplace safety and reducing workplace injury.

Kondrad, Monica

2009-01-01

Providing a medical home for children with special healthcare needs presents challenges such as allowing time during the office visit to address the child's and parent's concerns, the provision of comprehensive medical care, and identifying resources to support these children in the community. The care coordinator serves as a link between the child/family, physician, school, and community resource to promote communication and prevent duplication of services to ensure optimal outcomes for these children. A plan of care or medical summary is developed by the care coordinator with input from the parent/child, pediatrician, specialists, and allied healthcare personnel to use as a communication tool with staff/physicians in the emergency room, new specialists, schools, and community agencies to promote access to services.

2012-03-01

This overview paper provides an introduction to work on naturally-occurring speech data, combining techniques of conversation analysis with techniques and methods from phonetics. The paper describes the development of the field, highlighting current challenges and progress in interdisciplinary work. It considers the role of quantification and its relationship to a qualitative methodology. It presents the conversation analytic notion of sequence as a version of context, and argues that sequences of talk constrain relevant phonetic design, and so provide one account for variability in naturally occurring speech. The paper also describes the manipulation of speech and language on many levels simultaneously. All of these themes occur and are explored in more detail in the papers contained in this special issue.

Dhawan, Atam P

2016-01-01

Recent advances in biosensors, medical instrumentation, and information processing and communication technologies (ICT) have enabled significant improvements in healthcare. However, these technologies have been mainly applied in clinical environments, such as hospitals and healthcare facilities, under managed care by well-trained and specialized individuals. The global challenge of providing quality healthcare at affordable cost leads to the proposed paradigm of P reventive, Personalized, and Precision Medicine that requires a seamless use of technology and infrastructure support for patients and healthcare providers at point-of-care (POC) locations including homes, semi or pre-clinical facilities, and hospitals. The complexity of the global healthcare challenge necessitates strong collaborative interdisciplinary synergies involving all stakeholder groups including academia, federal research institutions, industry, regulatory agencies, and clinical communities. It is critical to evolve with collaborative efforts on the translation of research to technology development toward clinical validation and potential healthcare applications. This special issue is focused on technology innovation and translational research for POC applications with potential impact in improving global healthcare in the respective areas. Some of these papers were presented at the NIH-IEEE Strategic Conference on Healthcare Innovations and POC Technologies for Precision Medicine (HI-POCT) held at the NIH on November 9-10, 2015. The papers included in the Special Issue provide a spectrum of critical issues and collaborative resources on translational research of advanced POC devices and ICT into global healthcare environment.

Dire deadlines: coping with dysfunctional family dynamics in an end-of-life care setting.

2009-01-01

Working in a hospice and being able to focus on individualized, specialized end-of-life care is a privilege for the hospice staff member. However, it also presents the hospice staff with unique challenges. This descriptive study is based upon two cases from an end-of-life care setting in Denmark, where dysfunctional family dynamics presented added challenges to the staff members in their efforts to provide optimal palliative care. The hospice triad--the patient, the staff member and the family member--forms the basis for communication and intervention in a hospice. Higher expectations and demands of younger, more well-informed patients and family members challenge hospice staff in terms of information and communication when planning for care. The inherent risk factors of working with patients in the terminal phase of life become a focal point in the prevention of the development of compassion fatigue among staff members. A series of coping strategies to more optimally manage dysfunctional families in a setting where time is of the essence are then presented in an effort to empower the hospice team, to prevent splitting among staff members, and to improve quality of care.

Mitra, S. S.; Doron, O.; Chen, A. X.; ...

2015-06-18

Rapid in-situ analytical techniques are attractive for characterizing Special Nuclear Material (SNM). Present techniques are time consuming, and require sample dissolution. Proof-of-principal studies are performed to demonstrate the utility of employing low energy neutrons from a portable pulsed neutron generator for non-destructive isotopic analysis of nuclear material. In particular, time-sequenced data acquisition, operating synchronously with the pulsing of a neutron generator, partitions the characteristic elemental prompt gamma-rays according to the type of the reaction; inelastic neutron scattering reactions during the ON state and thermal neutron capture reactions during the OFF state of the generator. Thus, the key challenge is isolatingmore » these signature gamma- rays from the prompt fission and β-delayed gamma-rays that are also produced during the neutron interrogation. A commercial digital multi-channel analyzer has been specially customized to enable time-resolved gamma-ray spectral data to be acquired in multiple user-defined time bins within each of the ON/OFF gate periods of the neutron generator. Preliminary results on new signatures from depleted uranium as well as modeling and benchmarking of the concept are presented, however this approach should should be applicable for virtually all forms of SNM.« less

Saiful Huq, Josep Puxeu Vaque, Daniel Zucca Aparicio, Tatiana Krylova, Yuri Kirpichev, Eric Ford, Caridad Borras Stereotactic Radiation Therapy (SRT) utilizes small static and dynamic (IMRT) fields, to successfully treat malignant and benign diseases using techniques such as Stereotactic Radiosurgery (SRS) and Stereotactic Body Radiation Therapy (SBRT). SRT is characterized by sharp dose gradients for individual fields and their resultant dose distributions. For appropriate targets, small field radiotherapy offers improved treatment quality by allowing better sparing of organs at risk while delivering the prescribed target dose. Specialized small field treatment deliverymore » systems, such as robotic-controlled linear accelerators, gamma radiosurgery units, and dynamic arc linear accelerators may utilize rigid fixation, image guidance, and tumor tracking, to insure precise dose delivery to static or moving targets. However, in addition to great advantages, small field delivery techniques present special technical challenges for dose calibration due to unique geometries and small field sizes not covered by existing reference dosimetry protocols such as AAPM TG-51 or IAEA TRS 398. In recent years extensive research has been performed to understand small field dosimetry and measurement instrumentation. AAPM, IAEA and ICRU task groups are expected to provide soon recommendations on the dosimetry of small radiation fields. In this symposium we will: 1] discuss the physics, instrumentation, methodologies and challenges for small field radiation dose measurements; 2] review IAEA and ICRU recommendations on prescribing, recording and reporting of small field radiation therapy; 3] discuss selected clinical applications and technical aspects for specialized image-guided, small field, linear accelerator based treatment techniques such as IMRT and SBRT.

2015-12-01

We discuss application of three particle in cell (PIC) codes to the problems relevant to turbulence dissipation challenge. VPIC is a fully kinetic code extensively used to study a variety of diverse problems ranging from laboratory plasmas to astrophysics. PSC is a flexible fully kinetic code offering a variety of algorithms that can be advantageous to turbulence simulations, including high order particle shapes, dynamic load balancing, and ability to efficiently run on Graphics Processing Units (GPUs). Finally, HYPERS is a novel hybrid (kinetic ions+fluid electrons) code, which utilizes asynchronous time advance and a number of other advanced algorithms. We present examples drawn both from large-scale turbulence simulations and from the test problems outlined by the turbulence dissipation challenge. Special attention is paid to such issues as the small-scale intermittency of inertial range turbulence, mode content of the sub-proton range of scales, the formation of electron-scale current sheets and the role of magnetic reconnection, as well as numerical challenges of applying PIC codes to simulations of astrophysical turbulence.

The multifactorial etiology of depression obliges needs an individual assessment, the psychopharmacological approach involving a biopsychosocial analysis for each individual case. The rebalancing of the depressive patient, seen as a return to a normal level of psychosocial functioning and reduced risk of relapse is achieved with a prompt and constant support of specialized teams. Treatment should include psychopharmacological and psychosocial approaches, the results being interrelated and contributing to the prognosis of the disorder. Progress in clinical and pharmacological research, vivid dynamics of socio-economic environment, the complexity of diagnostic evaluation and the need for an interdisciplinary approach may cause difficulties in addressing the depressive patient and the ethical controversies. The aim of this paper is to present a brief analysis of challenges encountered in the present psychiatric practice, starting from the heterogeneity of depressive manifestations and finishing with the prioritization of interventional forms.

We review the advantages and disadvantages of the two kinds of information commonly used for such inferences--morphological and molecular data--as applied to the systematics of metazoan parasites generally, with special attention to the malaria parasites. The problems that potentially confound the use of morphology in parasites include challenges to consistent specimen preservation, plasticity of features depending on hosts or other environmental factors, and morphological convergence. Molecular characters such as DNA sequences present an alternative data source and are particularly useful when not all the parasite's life stages are present or when parasitaemia is low. Nonetheless, molecular data can bring challenges that include troublesome DNA isolation, paralogous gene copies, difficulty in developing molecular markers, and preferential amplification in mixed species infections. Given the differential benefits and shortcomings of both molecular and morphological characters, both should be implemented in parasite taxonomy and phylogenetics.

Multi -omics and metabolic modelling pipelines: challenges and tools for systems microbiology.

PubMed

Fondi, Marco; Liò, Pietro

2015-02-01

Integrated -omics approaches are quickly spreading across microbiology research labs, leading to (i) the possibility of detecting previously hidden features of microbial cells like multi-scale spatial organization and (ii) tracing molecular components across multiple cellular functional states. This promises to reduce the knowledge gap between genotype and phenotype and poses new challenges for computational microbiologists. We underline how the capability to unravel the complexity of microbial life will strongly depend on the integration of the huge and diverse amount of information that can be derived today from -omics experiments. In this work, we present opportunities and challenges of multi -omics data integration in current systems biology pipelines. We here discuss which layers of biological information are important for biotechnological and clinical purposes, with a special focus on bacterial metabolism and modelling procedures. A general review of the most recent computational tools for performing large-scale datasets integration is also presented, together with a possible framework to guide the design of systems biology experiments by microbiologists.

Web Design for Space Operations: An Overview of the Challenges and New Technologies Used in Developing and Operating Web-Based Applications in Real-Time Operational Support Onboard the International Space Station, in Astronaut Mission Planning and Mission Control Operations

NASA Technical Reports Server (NTRS)

Khan, Ahmed

2010-01-01

The International Space Station (ISS) Operations Planning Team, Mission Control Centre and Mission Automation Support Network (MAS) have all evolved over the years to use commercial web-based technologies to create a configurable electronic infrastructure to manage the complex network of real-time planning, crew scheduling, resource and activity management as well as onboard document and procedure management required to co-ordinate ISS assembly, daily operations and mission support. While these Web technologies are classified as non-critical in nature, their use is part of an essential backbone of daily operations on the ISS and allows the crew to operate the ISS as a functioning science laboratory. The rapid evolution of the internet from 1998 (when ISS assembly began) to today, along with the nature of continuous manned operations in space, have presented a unique challenge in terms of software engineering and system development. In addition, the use of a wide array of competing internet technologies (including commercial technologies such as .NET and JAVA ) and the special requirements of having to support this network, both nationally among various control centres for International Partners (IPs), as well as onboard the station itself, have created special challenges for the MCC Web Tools Development Team, software engineers and flight controllers, who implement and maintain this system. This paper presents an overview of some of these operational challenges, and the evolving nature of the solutions and the future use of COTS based rich internet technologies in manned space flight operations. In particular this paper will focus on the use of Microsoft.s .NET API to develop Web-Based Operational tools, the use of XML based service oriented architectures (SOA) that needed to be customized to support Mission operations, the maintenance of a Microsoft IIS web server onboard the ISS, The OpsLan, functional-oriented Web Design with AJAX

We present a case of an 18-year-old male patient who, after two years of inappropriate treatment for cutaneous leishmaniasis, began to show nodules arising at the edges of the former healing scar. He was immune competent and denied any trauma. The diagnosis of recurrent cutaneous leishmaniasis was made following positive culture of aspirate samples. The patient was treated with N-methylglucamine associated with pentoxifylline for 30 days. Similar cases require special attention mainly because of the challenges imposed by treatment.

Correlated Imaging – A Grand Challenge in Chemical Analysis

PubMed Central

Masyuko, Rachel; Lanni, Eric; Sweedler, Jonathan V.; Bohn, Paul W.

2013-01-01

Correlated chemical imaging is an emerging strategy for acquisition of images by combining information from multiplexed measurement platforms to track, visualize, and interpret in situ changes in the structure, organization, and activities of interesting chemical systems, frequently spanning multiple decades in space and time. Acquiring and correlating information from complementary imaging experiments has the potential to expose complex chemical behavior in ways that are simply not available from single methods applied in isolation, thereby greatly amplifying the information gathering power of imaging experiments. However, in order to correlate image information across platforms, a number of issues must be addressed. First, signals are obtained from disparate experiments with fundamentally different figures of merit, including pixel size, spatial resolution, dynamic range, and acquisition rates. In addition, images are often acquired on different instruments in different locations, so the sample must be registered spatially so that the same area of the sample landscape is addressed. The signals acquired must be correlated in both spatial and temporal domains, and the resulting information has to be presented in a way that is readily understood. These requirements pose special challenges for image cross-correlation that go well beyond those posed in single technique imaging approaches. The special opportunities and challenges that attend correlated imaging are explored by specific reference to correlated mass spectrometric and Raman imaging, a topic of substantial and growing interest.

Research involving human subjects after public health emergencies and disasters may pose ethical challenges. These challenges may include concerns about the vulnerability of prospective disaster research participants, increased research burden among disaster survivors approached by multiple research teams, and potentially reduced standards in the ethical review of research by institutional review boards (IRBs) due to the rush to enter the disaster field. The NIEHS Best Practices Working Group for Special IRB Considerations in the Review of Disaster Related Research was formed to identify and address ethical and regulatory challenges associated with the review of disaster research. The working group consists of a diverse collection of disaster research stakeholders across a broad spectrum of disciplines. The working group convened in July 2016 to identify recommendations that are instrumental in preparing IRBs to review protocols related to public health emergencies and disasters. The meeting included formative didactic presentations and facilitated breakout discussions using disaster-related case studies. Major thematic elements from these discussions were collected and documented into 15 working group recommendations, summarized in this article, that address topics such as IRB disaster preparedness activities, informed consent, vulnerable populations, confidentiality, participant burden, disaster research response integration and training, IRB roles/responsibilities, community engagement, and dissemination of disaster research results. https://doi.org/10.1289/EHP2378.

Summary Objectives To provide an editorial introduction to the 2015 IMIA Yearbook of Medical Informatics. Methods We provide a brief overview of the 2015 special topic “Patient-Centered Care Coordination”, discuss the addition of two new sections to the Yearbook, Natural Language Processing and Public Health & Epidemiology Informatics, and present our editorial plans for the upcoming celebration of the 25th anniversary of the Yearbook. Results Care delivery currently occurs through the processing of complex clinical pathways designed for increasingly multi-morbid patients by various practitioners in different settings. To avoid the consequences of the fragmentation of services, care should be organized to coordinate all providers, giving them the opportunity to share the same holistic view of the patient’s condition, and to be informed of the planned clinical pathway that establishes the roles and interventions of each one. The adoption and use of electronic health records (EHRs) is a solution to address health information sharing and care coordination challenges. However, while EHRs are necessary, they are not sufficient to achieve care coordination, creating information availability does not mean the information will be accessed. This edition of the Yearbook acknowledges the fact that health information technology (HIT), and EHRs in particular, are not yet fully addressing the challenges in care coordination. Emerging trends, tools, and applications of HIT to support care coordination are presented through the keynote paper, survey papers, and working group contributions. Conclusions In 2015, the IMIA Yearbook has been extended to emphasize two fields of biomedical informatics through new sections. Next year, the 25th anniversary of the Yearbook will be celebrated in grand style! A special issue with a touch of reflection, a bit of rediscovery, and some “science-fiction” will be published in addition to the usual edition. PMID:26123912

Context: The rapid emergence of new technologies support collection and use of a wide variety of data from clinical, genomic, social and behavioral, environmental, and financial sources, and have a great impact on the governance of personal health information. Papers in the special issue: The papers in this special issue on governance touch on the topic from a variety of focuses, including leadership perspectives, local and federal case studies, and the future importance of patient engagement. Themes: This special issue focuses on three major themes—that data governance is growing in importance and presenting new challenges that must be addressed, that health care organizations must prioritize governance design, implementation, and functions as a priority, and that governance seems to be naturally converging on an archetype as described by this set of papers. Future State of Governance: In order to deal with issues such as data de- and re-identification, data governance must be studied as its own field. PMID:27141525

Healing the healer: one step at a time.

Health care workers have the most challenging of professions. They are expected to work long hours while demonstrating compassion and care for the patients that they serve. Although health care practitioners are among the most disciplined of working professionals, they are often some of the unhealthiest of individuals, facing enormous amounts of stress in their lives. Healing the Healer: One Step at a Time is a 6-week health fitness program. It explores the unique challenges faced in the field of health care and teaches techniques to address those challenges head on. Healing the Healer uses Nordic walking as the exercise portion of the class. The case study examines the structure, purpose, and design of this 6-week course. Special attention is given to four basic sections: balance, pacing, joy, and discipline. The arguments presented in this article are theory based and supported by case study evidence.

Enhancing astronaut performance using sensorimotor adaptability training

Astronauts experience disturbances in balance and gait function when they return to Earth. The highly plastic human brain enables individuals to modify their behavior to match the prevailing environment. Subjects participating in specially designed variable sensory challenge training programs can enhance their ability to rapidly adapt to novel sensory situations. This is useful in our application because we aim to train astronauts to rapidly formulate effective strategies to cope with the balance and locomotor challenges associated with new gravitational environments—enhancing their ability to “learn to learn.” We do this by coupling various combinations of sensorimotor challenges with treadmill walking. A unique training system has been developed that is comprised of a treadmill mounted on a motion base to produce movement of the support surface during walking. This system provides challenges to gait stability. Additional sensory variation and challenge are imposed with a virtual visual scene that presents subjects with various combinations of discordant visual information during treadmill walking. This experience allows them to practice resolving challenging and conflicting novel sensory information to improve their ability to adapt rapidly. Information obtained from this work will inform the design of the next generation of sensorimotor countermeasures for astronauts. PMID:26441561

2017-08-01

Determining the most appropriate level of care for patients in the prehospital setting during medical emergencies is essential. A large body of literature suggests that, compared with Basic Life Support (BLS) care, Advanced Life Support (ALS) care is not associated with increased patient survival or decreased mortality. The purpose of this special report is to synthesize the literature to identify common study design and analytic challenges in research studies that examine the effect of ALS, compared to BLS, on patient outcomes. The challenges discussed in this report include: (1) choice of outcome measure; (2) logistic regression modeling of common outcomes; (3) baseline differences between study groups (confounding); (4) inappropriate statistical adjustment; and (5) inclusion of patients who are no longer at risk for the outcome. These challenges may affect the results of studies, and thus, conclusions of studies regarding the effect of level of prehospital care on patient outcomes should require cautious interpretation. Specific alternatives for avoiding these challenges are presented. Li T , Jones CMC , Shah MN , Cushman JT , Jusko TA .

Phonological universals constrain the processing of nonspeech stimuli.

PubMed

Berent, Iris; Balaban, Evan; Lennertz, Tracy; Vaknin-Nusbaum, Vered

2010-08-01

Domain-specific systems are hypothetically specialized with respect to the outputs they compute and the inputs they allow (Fodor, 1983). Here, we examine whether these 2 conditions for specialization are dissociable. An initial experiment suggests that English speakers could extend a putatively universal phonological restriction to inputs identified as nonspeech. A subsequent comparison of English and Russian participants indicates that the processing of nonspeech inputs is modulated by linguistic experience. Striking, qualitative differences between English and Russian participants suggest that they rely on linguistic principles, both universal and language-particular, rather than generic auditory processing strategies. Thus, the computation of idiosyncratic linguistic outputs is apparently not restricted to speech inputs. This conclusion presents various challenges to both domain-specific and domain-general accounts of cognition. 2010 APA, all rights reserved

Will learning to solve one-step equations pose a challenge to 8th grade students?

NASA Astrophysics Data System (ADS)

Ngu, Bing Hiong; Phan, Huy P.

2017-08-01

Assimilating multiple interactive elements simultaneously in working memory to allow understanding to occur, while solving an equation, would impose a high cognitive load. Element interactivity arises from the interaction between elements within and across operational and relational lines. Moreover, operating with special features (e.g. negative pronumeral) poses additional challenge to master equation solving skills. In an experiment, 41 8th grade students (girls = 16, boys = 25) sat for a pre-test, attended a session about equation solving, completed an acquisition phase which constituted the main intervention and were tested again in a post-test. The results showed that at post-test, students performed better on one-step equations tapping low rather than high element interactivity knowledge. In addition, students performed better on those one-step equations that contained no special features. Thus, both the degree of element interactivity and the operation with special features affect the challenge posed to 8th grade students on learning how to solve one-step equations.

Gas-gap heat switches can serve as an effective means of thermally disconnecting a standby cryocooler when the primary (operating) cooler is connected and vice versa. The final phase of the development and test of a cryogenic heat switch designed for loads ranging from 2 watts at 8 K, to 100 watts at 80 K are described. Achieved heat-switch on/off conductance ratio ranged from 11,000 at 8 K to 2200 at 80 K. A particularly challenging element of heat-switch design is achieving satisfactory operation when large temperatures differentials exist across the switch. A special series of tests and analyses was conducted and used in this Phase-2 activity to evaluate the developed switches for temperature differentials ranging up to 200 K. Problems encountered at the maximum levels are described and analyzed, and means of avoiding the problems in the future are presented. A comprehensive summary of the overall heat-switch design methodology is also presented with special emphasis on lessons learned over the course of the 4-year development effort.

Safety of plant-made pharmaceuticals: product development and regulatory considerations based on case studies of two autologous human cancer vaccines.

PubMed

Tusé, Daniel

2011-03-01

Guidelines issued by regulatory agencies for the development of plant-made pharmaceutical (PMP) products provide criteria for product manufacturing and characterization, safety determination, containment and mitigation of environmental risks. Features of plant-made products do not always enable an easy fit within the criteria subscribed to by regulators. The unconventional nature of plant-based manufacturing processes and peculiarities of plant biology relative to that of traditional biological production systems have led to special considerations in the regulatory scrutiny of PMP. Presented in this review are case studies of two plant-made autologous (patient-specific) cancer vaccines, the nature of which introduced challenges to conventional and standardized development and preclinical evaluation routes. The rationale presented to FDA by the sponsors of each vaccine to build consensus and obtain variances to existing guidelines is discussed. While development of many plant-made biologics can be accomplished within the existing regulatory framework, the development of specialized products can be defended with rational arguments based on strong science.

Collaborative Paradigm of Preventive, Personalized, and Precision Medicine With Point-of-Care Technologies

PubMed Central

2016-01-01

Recent advances in biosensors, medical instrumentation, and information processing and communication technologies (ICT) have enabled significant improvements in healthcare. However, these technologies have been mainly applied in clinical environments, such as hospitals and healthcare facilities, under managed care by well-trained and specialized individuals. The global challenge of providing quality healthcare at affordable cost leads to the proposed paradigm of P reventive, Personalized, and Precision Medicine that requires a seamless use of technology and infrastructure support for patients and healthcare providers at point-of-care (POC) locations including homes, semi or pre-clinical facilities, and hospitals. The complexity of the global healthcare challenge necessitates strong collaborative interdisciplinary synergies involving all stakeholder groups including academia, federal research institutions, industry, regulatory agencies, and clinical communities. It is critical to evolve with collaborative efforts on the translation of research to technology development toward clinical validation and potential healthcare applications. This special issue is focused on technology innovation and translational research for POC applications with potential impact in improving global healthcare in the respective areas.

A 4-spot time-of-flight anemometer for small centrifugal compressor velocity measurements

NASA Technical Reports Server (NTRS)

Wernet, Mark P.; Skoch, Gary J.

1992-01-01

The application of laser anemometry techniques in turbomachinery facilities is a challenging dilemma requiring an anemometer system with special qualities. Here, we describe the use of a novel laser anemometry technique applied to a small 4.5 kg/s, 4:1 pressure ratio centrifugal compressor. Sample velocity profiles across the blade pitch are presented for a single location along the rotor. The results of the intra-blade passage velocity measurements will ultimately be used to verify CFD 3-D viscous code predictions.

Gao, David Yang

2016-10-01

A unified model is proposed for general optimization problems in multi-scale complex systems. Based on this model and necessary assumptions in physics, the canonical duality theory is presented in a precise way to include traditional duality theories and popular methods as special applications. Two conjectures on NP-hardness are proposed, which should play important roles for correctly understanding and efficiently solving challenging real-world problems. Applications are illustrated for both nonconvex continuous optimization and mixed integer nonlinear programming.

Talent identification and specialization in sport: an overview of some unanswered questions.

PubMed

Gonçalves C, E B; Rama L, M L; Figueiredo, António B

2012-12-01

The theory of deliberate practice postulates that experts are always made, not born. This theory translated to the youth-sport domain means that if athletes want to be high-level performers, they need to deliberately engage in practice during the specialization years, spending time wisely and always focusing on tasks that challenge current performance. Sport organizations in several countries around the world created specialized training centers where selected young talents practice under the supervision of experienced coaches in order to become professional athletes and integrate onto youth national teams. Early specialization and accurate observation by expert coaches or scouts remain the only tools to find a potential excellent athlete among a great number of participants. In the current study, the authors present 2 of the problems raised by talent search and the risks of such a search. Growth and maturation are important concepts to better understand the identification, selection, and development processes of young athletes. However, the literature suggests that sport-promoting strategies are being maintained despite the increased demands in the anthropometric characteristics of professional players and demands of actual professional soccer competitions. On the other hand, identifying biological variables that can predict performance is almost impossible.

Rapid development of entity-based data models for bioinformatics with persistence object-oriented design and structured interfaces.

PubMed

Ezra Tsur, Elishai

2017-01-01

Databases are imperative for research in bioinformatics and computational biology. Current challenges in database design include data heterogeneity and context-dependent interconnections between data entities. These challenges drove the development of unified data interfaces and specialized databases. The curation of specialized databases is an ever-growing challenge due to the introduction of new data sources and the emergence of new relational connections between established datasets. Here, an open-source framework for the curation of specialized databases is proposed. The framework supports user-designed models of data encapsulation, objects persistency and structured interfaces to local and external data sources such as MalaCards, Biomodels and the National Centre for Biotechnology Information (NCBI) databases. The proposed framework was implemented using Java as the development environment, EclipseLink as the data persistency agent and Apache Derby as the database manager. Syntactic analysis was based on J3D, jsoup, Apache Commons and w3c.dom open libraries. Finally, a construction of a specialized database for aneurysms associated vascular diseases is demonstrated. This database contains 3-dimensional geometries of aneurysms, patient's clinical information, articles, biological models, related diseases and our recently published model of aneurysms' risk of rapture. Framework is available in: http://nbel-lab.com.

The challenge of benchmarking health systems: is ICT innovation capacity more systemic than organizational dependent?

PubMed

Lapão, Luís Velez

2015-01-01

The article by Catan et al. presents a benchmarking exercise comparing Israel and Portugal on the implementation of Information and Communication Technologies in the healthcare sector. Special attention was given to e-Health and m-Health. The authors collected information via a set of interviews with key stakeholders. They compared two different cultures and societies, which have reached slightly different implementation outcomes. Although the comparison is very enlightening, it is also challenging. Benchmarking exercises present a set of challenges, such as the choice of methodologies and the assessment of the impact on organizational strategy. Precise benchmarking methodology is a valid tool for eliciting information about alternatives for improving health systems. However, many beneficial interventions, which benchmark as effective, fail to translate into meaningful healthcare outcomes across contexts. There is a relationship between results and the innovational and competitive environments. Differences in healthcare governance and financing models are well known; but little is known about their impact on Information and Communication Technology implementation. The article by Catan et al. provides interesting clues about this issue. Public systems (such as those of Portugal, UK, Sweden, Spain, etc.) present specific advantages and disadvantages concerning Information and Communication Technology development and implementation. Meanwhile, private systems based fundamentally on insurance packages, (such as Israel, Germany, Netherlands or USA) present a different set of advantages and disadvantages - especially a more open context for innovation. Challenging issues from both the Portuguese and Israeli cases will be addressed. Clearly, more research is needed on both benchmarking methodologies and on ICT implementation strategies.

Most existing holographic display methods concentrate on real object reconstruction, but there is a lack of research on object stories (revealing and presenting histories). To address this challenge, we propose a method, called 4 `ER' (leader, manager, implementer, presenter) to experience and respond objects in a special immersive environment. The key innovation of the 4'ER' method is to introduce the stories (political, historical, etc.) into hard copy holography, so as to synergy art and science for museum objects display. The hologram of an imitation of a blue and white porcelain jar from The Palace Museum, Beijing, China has been made, showing good performance and reflecting different pathway to knowledge.

Depression among older adults with diabetes mellitus.

PubMed

Park, Mijung; Reynolds, Charles F

2015-02-01

Older adults with Diabetes Mellitus (DM) experience greater risk for comorbid depression compared to those who do not have DM. Undetected, untreated or under-treated depression impinges an individual's ability to manage their DM successfully, hinders their adherence to treatment regime, and undermines provider-patient relationships. Thus, in the context of caring for older adults with DM, comorbid depression presents special challenges and opportunities for clinicians. In this article, we summarize the clinical presentation of late-life depression, potential mechanisms of comorbidity of depression and DM, importance of depression in the successful management of DM, and available best practice models for depression treatment.

Religious symptoms have been recognized as a presentation of obsessive-compulsive disorder (OCD) for centuries. The two main treatment strategies for OCD, cognitive behavior therapy (exposure and response prevention [ERP]), and SSRIs have been shown to be effective in religious OCD. The presentation of religious OCD within formal prayer, reported in Judaism and Islam, poses special challenges of inaccessibility of personal prayer, sanctity of the symptom, and the status of the therapist. A method of guided-prayer repetition, a variant of ERP, is described, and its successful application is reported in three cases of ultra-orthodox Jewish men with prayer as the main symptom of their religious OCD.

Hines, Lindsey; Petersen, Kirstin; Lum, Guo Zhan; Sitti, Metin

2017-04-01

This review comprises a detailed survey of ongoing methodologies for soft actuators, highlighting approaches suitable for nanometer- to centimeter-scale robotic applications. Soft robots present a special design challenge in that their actuation and sensing mechanisms are often highly integrated with the robot body and overall functionality. When less than a centimeter, they belong to an even more special subcategory of robots or devices, in that they often lack on-board power, sensing, computation, and control. Soft, active materials are particularly well suited for this task, with a wide range of stimulants and a number of impressive examples, demonstrating large deformations, high motion complexities, and varied multifunctionality. Recent research includes both the development of new materials and composites, as well as novel implementations leveraging the unique properties of soft materials. © 2016 WILEY-VCH Verlag GmbH & Co.

Dental education and special-needs patients: challenges and opportunities.

PubMed

McTigue, Dennis J

2007-01-01

Pediatric dentists have, by tradition and default, provided care for persons with special health care needs (PSHCN), regardless of age. Deinstitutionalization of PSHCN in the 1960s, however, overwhelmed the dental care system, and oral health care became one of the greatest unmet needs of this population. This presentation follows the history of training for dentists in this aspect of care, from the first demonstration programs in the 1970s to the current educational programs in U.S. dental schools. Today's dental students must be competent in assessing the treatment needs of PSHCN, but accreditation standards do not require competency in the treatment of this group of patients. Recommendations to rectify this include revising dental school curricula to be more patient-centered, improving technology in schools, earlier clinical experiences for dental students, and the use of community-based clinics.

Assessment of Adolescent Neurotoxicity: Rationale and Methodological Considerations

PubMed Central

Spear, Linda Patia

2007-01-01

This introduction to the special issue of Neurotoxicology and Teratology on “Risk of neurobehavioral toxicity in adolescence” begins by broadly considering the ontogeny and phylogeny of adolescence, and the potential value of animal models of adolescence. Major findings from the emerging neuroscience of adolescence are then highlighted to establish the importance of studies of adolescent neurotoxicity. A variety of methodological issues that are of particular relevance to adolescent exposures are then discussed. These include consideration of pharmacokinetic factors, inclusion of other-aged comparison group(s), and issues involving timing, route of administration, and exposure-induced alterations in growth rate. Despite such methodological challenges, research to determine whether adolescence is a time of increased vulnerability (or greater resiliency) to specific drugs and environmental toxicants is progressing rapidly, as exemplified by the work presented in the articles of this special issue.

The United States, as well as most developed and many developing nations worldwide, is becoming increasingly urban and suburban.Although urban, suburban, and commercial development account for less than one percent to just over 20% of land use among states, 50-90% of the residents of those states can be classified as urban or suburban dwellers. The population of the U.S. as a whole has risen from being > 95% rural in the 1790s to about 80% urban-suburban today. With these changes in land use and demographic patterns come changes in values and attitudes; many urbanites and suburbanites view wildlife and nature differently than rural residents. These are among the challenges faced by wildlife biologists and natural resource managers in a rapidly urbanizing world. In 2003, we convened a symposium to discuss issues related to suburban wildlife. The papers presented in this special issue of Urban Ecosystems address the lessons learned from the early and recently rapidly expanding literature, the challenges we face today, and the opportunities that can help deal with what is one of the biggest challenges to conservation in a modernizing world. ?? 2005 Springer Science + Business Media, Inc.

Systemic lupus erythematosus diagnosis and management.

PubMed

Thong, Bernard; Olsen, Nancy J

2017-04-01

SLE presents many challenges for clinicians. The onset of disease may be insidious, with many different symptoms and signs, making early and accurate diagnosis challenging. Tests for SLE in the early stages lack specificity; those that are useful later often appear only after organ damage is manifest. Disease patterns are highly variable; flares are not predictable and not always associated with biomarkers. Children with SLE may have severe disease and present special management issues. Older SLE patients have complicating co-morbid conditions. Therapeutic interventions have improved over recent decades, but available drugs do not adequately control disease in many patients, and successful outcomes are limited by off-target effects; some of these become manifest with longer duration of treatment, now in part revealed by improved rates of survival. Despite all of these challenges, advances in understanding the biological basis of SLE have translated into more effective approaches to patient care. This review considers the current state of SLE diagnosis and management, with a focus on new approaches and anticipated advances. © The Author 2016.

Gender Dysphoria and Co-Occurring Autism Spectrum Disorders: Review, Case Examples, and Treatment Considerations.

PubMed

Jacobs, Laura A; Rachlin, Katherine; Erickson-Schroth, Laura; Janssen, Aron

2014-12-01

Transgender and gender nonconforming people who fulfill diagnostic criteria for autism spectrum disorders (ASDs) often present to mental health providers with concerns that are distinct from those without ASDs. Gender Dysphoria (GD) and ASDs have been proposed to share etiologic mechanisms and there is evidence that ASDs may be more common in transgender and gender nonconforming people. We explore the impact of ASD characteristics on individual gender identity, expression, and the process of psychotherapy. The authors present two case studies of high-functioning individuals with ASD and GD diagnoses. The limited ability to articulate an inner experience, deficits in Theory of Mind (ToM), along with the intolerance of ambiguity as a manifestation of the cognitive rigidity characteristic of ASDs, may present special difficulties to gender identity formation and consolidation and create challenges in psychotherapy. The authors suggest that ASDs do not preclude gender transition and that individuals with high-functioning ASDs are capable of making informed decisions regarding their medical care and life choices. The authors also consider possible challenges and suggest techniques for assisting such clients in exploring their gender identities.

PubMed

Chew, Leslie C T; King, Nigel M; O'Donnell, David

2006-03-01

Autism is defined as a rare and severe psychiatric disorder of childhood. It is marked by severe difficulties in communicating, and forming relationships with other people, in developing language, repetitive and limited patterns of behaviour and obsessive resistance to small changes in familiar surroundings. Hence, affected children offer a special challenge to the practising dentist. To meet this challenge, it is necessary to understand the condition and how to manage its varying presentations in different individuals. The purpose of this article is to review the literature on the topic of autism with an emphasis on the dental perspective. A better understanding of the effects of autism on the behaviour of an affected individual provides the dental practitioner with the opportunity to deliver oral healthcare in an empathetic and appropriate manner.

Fingertip amputation is a challenging injury to manage. Among various reconstructive procedures, replantation results in superior outcome, but is seldom considered in many institutions. From the identification of vessel ends to reanastomosis of the submillimeter vessels, fingertip's highly specialized anatomy requires technical excellence. By addressing these anatomic challenges, fingertip replantation can be a routine reconstructive option for microvascular surgeons. PMID:24872765

Increased protein intake in military special operations.

PubMed

Ferrando, Arny A

2013-11-01

Special operations are so designated for the specialized military missions they address. As a result, special operations present some unique metabolic challenges. In particular, soldiers often operate in a negative energy balance in stressful and demanding conditions with little opportunity for rest or recovery. In this framework, findings inferred from the performance literature suggest that increased protein intake may be beneficial. In particular, increased protein intake during negative caloric balance maintains lean body mass and blood glucose production. The addition of protein to mixed macronutrient supplements is beneficial for muscle endurance and power endpoints, and the use of amino acids improves gross and fine motor skills. Increasing protein intake during periods of intense training and/or metabolic demand improves subsequent performance, improves muscular recovery, and reduces symptoms of psychological stress. Consumption of protein before sleep confers the anabolic responses required for the maintenance of lean mass and muscle recovery. A maximal response in muscle protein synthesis is achieved with the consumption of 20-25 g of protein alone. However, higher protein intakes in the context of mixed-nutrient ingestion also confer anabolic benefits by reducing protein breakdown. Restricted rations issued to special operators provide less than the RDA for protein ( ∼ 0.6 g/kg), and these soldiers often rely on commercial products to augment their rations. The provision of reasonable alternatives and/or certification of approved supplements by the U.S. Department of Defense would be prudent.

Spacecraft parachutes are typically used in multiple stages, starting with a "reefed" stage where a cable along the parachute skirt constrains the diameter to be less than the diameter in the subsequent stage. After a certain period of time during the descent, the cable is cut and the parachute "disreefs" (i.e. expands) to the next stage. Computing the parachute shape at the reefed stage and fluid-structure interaction (FSI) modeling during the disreefing involve computational challenges beyond those we have in FSI modeling of fully-open spacecraft parachutes. These additional challenges are created by the increased geometric complexities and by the rapid changes in the parachute geometry. The computational challenges are further increased because of the added geometric porosity of the latest design, where the "windows" created by the removal of panels and the wider gaps created by the removal of sails compound the geometric and flow complexity. Orion spacecraft main parachutes will have three stages, with computation of the Stage 1 shape and FSI modeling of disreefing from Stage 1 to Stage 2 being the most challenging. We present the special modeling techniques we devised to address the computational challenges and the results from the computations carried out. We also present the methods we devised to calculate for a parachute gore the radius of curvature in the circumferential direction. The curvature values are intended for quick and simple engineering analysis in estimating the structural stresses.

Spectrally tunable liquid crystal filters provide numerous advantages and several challenges in space applications. We discuss the tradeoffs in design elements for tunable liquid crystal birefringent filters with special consideration required for space exploration applications. In this paper we present a summary of our development of tunable filters for NASA space exploration. In particular we discuss the application of tunable liquid crystals in guidance navigation and control in space exploration programs. We present a summary of design considerations for improving speed, field of view, transmission of liquid crystal tunable filters for space exploration. In conclusion, the current state of the art of several NASA LaRC assembled filters is presented and their performance compared to the predicted spectra using our PolarTools modeling software.

The clinics of acute coronary syndrome

Rastelli, Gianni

2016-01-01

Risk stratification and management of patients with chest pain continues to be challenging despite considerable efforts made in the last decades by many clinicians and researchers. The throutful evaluation necessitates that the physicians have a high index of suspicion for acute coronary syndrome (ACS) and always keep in mind the myriad of often subtle and atypical presentations of ischemic heart disease, especially in certain patient populations such as the elderly ones. In this article we aim to review and discuss the available evidence on the value of clinical presentation in patients with a suspected ACS, with special emphasis on history, characteristics of chest pain, associated symptoms, atypical presentations, precipitating and relieving factors, drugs, clinical rules and significance of clinical Gestalt.

Spann, James F.

2006-01-01

This special issue of the Journal of' Atmospheric and Solar-Terrestrial Physics is a compilation of 23 papers presented at The 2004 Huntsville Modeling Workshop: Challenges to Modeling thc San-Earth System held in Huntsville, AB on October 18-22, 2004. The title of the workshop appropriately captures the theme of what was presented and discussed by the 120 participants. Currently, end-to-end modeling of the Sun-Earth system is a major goal of the National Space Weather and NASA living with a star (LWS) programs. While profound advances have been made in modeling isolated regions of the Sun-Earth system, minimal progress has been achieved in modeling the end-to-end system. The transfer of mass, energy and momentum through the coupled Sun-Earth system spans a wide range of scales inn time and space. The uncertainty in the underlying physics responsible for coupling contiguous regions of the Sun-Earth system is recognized as a significant barrier to progress

Adaptive management of natural resources-framework and issues

USGS Publications Warehouse

Williams, B.K.

2011-01-01

Adaptive management, an approach for simultaneously managing and learning about natural resources, has been around for several decades. Interest in adaptive decision making has grown steadily over that time, and by now many in natural resources conservation claim that adaptive management is the approach they use in meeting their resource management responsibilities. Yet there remains considerable ambiguity about what adaptive management actually is, and how it is to be implemented by practitioners. The objective of this paper is to present a framework and conditions for adaptive decision making, and discuss some important challenges in its application. Adaptive management is described as a two-phase process of deliberative and iterative phases, which are implemented sequentially over the timeframe of an application. Key elements, processes, and issues in adaptive decision making are highlighted in terms of this framework. Special emphasis is given to the question of geographic scale, the difficulties presented by non-stationarity, and organizational challenges in implementing adaptive management. ?? 2010.

Multi-imager compatible actuation principles in surgical robotics.

PubMed

Stoianovici, D

2005-01-01

Today's most successful surgical robots are perhaps surgeon-driven systems, such as the daVinci (Intuitive Surgical Inc., USA, www.intuitivesurgical.com). These have already enabled surgery that was unattainable with classic instrumentation; however, at their present level of development, they have limited utility. The drawback of these systems is that they are independent self-contained units, and as such, they do not directly take advantage of patient data. The potential of these new surgical tools lies much further ahead. Integration with medical imaging and information are needed for these devices to achieve their true potential. Surgical robots and especially their subclass of image-guided systems require special design, construction and control compared to industrial types, due to the special requirements of the medical and imaging environments. Imager compatibility raises significant engineering challenges for the development of robotic manipulators with respect to imager access, safety, ergonomics, and above all the non-interference with the functionality of the imager. These apply to all known medical imaging types, but are especially challenging for achieving compatibility with the class of MRI systems. Even though a large majority of robotic components may be redesigned to be constructed of MRI compatible materials, for other components such as the motors used in actuation, prescribing MRI compatible materials alone is not sufficient. The electromagnetic motors most commonly used in robotic actuation, for example, are incompatible by principle. As such, alternate actuation principles using "intervention friendly" energy should be adopted and/or devised for these special surgical and radiological interventions. This paper defines the new concept of Multi-Imager Compatibility of surgical manipulators and describes its requirements. Subsequently, the paper gives several recommendations and proposes new actuation principles for this concept. Several implementations have been constructed and tested, and the results are presented here. This is the first paper addressing these issues. Copyright 2005 Robotic Publications Ltd.

Skilled interaction among professional carers in special accommodations for adult people with learning disabilities.

Communicative difficulties affect interactions between people with learning disabilities and their carers. Despite such difficulties, however, some carers seem to interact successfully with people who have limited ability to communicate verbally and exhibit challenging behaviour. This study aims to illuminate skilled interaction among carers working in special accommodations for people with learning disabilities. Interactions between 16 caregivers and 11 residents with learning disabilities were recorded on video. Verbal and non-verbal interaction skills among the carers were identified. Four caring situations with people with learning disabilities were chosen to illuminate skilled interaction. The transcribed text was subjected to qualitative content analysis and core stories were created. The results show that skilled interaction between the carers and the people with learning disabilities is based upon being confirming, sharing daily life experience, giving time and space, and using congruent and distinct language. In this paper we present examples that offer concrete suggestions of how to promote successful interaction and create meaning in the shared day-to-day life in special accommodations for people with learning disabilities. © 2012 John Wiley & Sons Ltd.

Epidemiology of breast cancer in Malaysia.

PubMed

Yip, Cheng Har; Taib, Nur Aishah Mohd; Mohamed, Ibraham

2006-01-01

Data from the National Cancer Registry of Malaysia for 2004 provide an age-standardised incidence rate (ASR) of 46.2 per 100,000 women. This means that approximately 1 in 20 women in the country develop breast cancer in their lifetime. However, the rate differs between the three main races, the Malays, Chinese and Indians. The age standardized incidence in Chinese is the highest, with 59.7 per 100,000, followed by the Indians at 55.8 per 100,000. The Malays have the lowest incidence of 33.9 per 100,000. This translates into 1 in 16 Chinese, 1 in 16 Indian and 1 in 28 Malay women developing breast cancer at some stage in their lives. The commonest age at presentation is between 40-49 years, with just over 50% of the cases under the age of 50 years, 16.8% below 40, and 2% under 30. Some 55.7% of all cases were found to be ER positive. The commonest presenting symptom was a lump in the breast in over 90% of cases, generally felt by the woman herself. The mean size of the lump was 4.2 cm, and on average, the women waited 3 months before seeking medical attention. Over the 12-year period from 1993 to 2004, about 60-70% of women presented with early stage (Stages 1-2) while 30-40% presented with late breast cancer (Stages 3-4). Especially Malays present at later stages and with larger tumours. Consequently their survival is worse than with Chinese and Indian women. The challenge in Malaysia is to be able to provide a comprehensive service in the diagnosis and treatment of breast cancer, and this requires training of a team of health professionals dedicated to breast health, such as breast surgeons, radiologists specializing in breast imaging, breast pathologists, plastic surgeons specializing in breast reconstruction, medical and radiation oncologists, psycho-oncologists, counselors, and breast nurses. Advocacy can play a role here in galvanizing the political will to meet this challenge.

2013-01-01

This paper describes the results of a special breakout session of the NASA Independent Verification and Validation (IV&V) Workshop held in the fall of 2012 entitled "V&V of Fault Management: Challenges and Successes." The NASA IV&V Program is in a unique position to interact with projects across all of the NASA development domains. Using this unique opportunity, the IV&V program convened a breakout session to enable IV&V teams to share their challenges and successes with respect to the V&V of Fault Management (FM) architectures and software. The presentations and discussions provided practical examples of pitfalls encountered while performing V&V of FM including the lack of consistent designs for implementing faults monitors and the fact that FM information is not centralized but scattered among many diverse project artifacts. The discussions also solidified the need for an early commitment to developing FM in parallel with the spacecraft systems as well as clearly defining FM terminology within a project.

Canzian, Blaise; Barentine, J.; Hull, T.

2012-01-01

L-3 Integrated Optical Systems (IOS) Division has been selected by the National Solar Observatory (NSO) to make the Top End Optical Assembly (TEOA) for the 4-meter Advanced Technology Solar Telescope (ATST) to operate at Haleakala, Maui. ATST will perform to a very high optical performance level in a difficult thermal environment. The TEOA, containing the 0.65-meter silicon carbide secondary mirror and support, mirror thermal management system, mirror positioning and fast tip-tilt system, field stop with thermally managed heat dump, thermally managed Lyot stop, safety interlock and control system, and support frame, operates in the "hot spot” at the prime focus of the ATST and so presents special challenges. In this paper, we will describe the L-3 IOS technical approach to meet these challenges, including subsystems for opto-mechanical positioning, rejected and stray light control, wavefront tip-tilt compensation, and thermal management. Key words: ATST, TEOA, L-3 IOS, thermal management, silicon carbide (SiC) mirrors, hexapods, solar astronomy

International Year of Planet Earth - Accomplishments, Activities, Challenges and Plans in Mexico

2009-12-01

The International Year of Planet Earth started as a joint initiative by UNESCO and IUGS with the participation of several geosciences organizations, and developed into a major international geosciences program for the triennium 2007-2009, with the inclusion and participation of national and regional committees. In this presentation we focus on current activities and plans in our country and the participation in international activities. Mexican community has been part of international programs since the International Geophysical Year, continuing through its participation in other programs, e.g., Upper Mantle, Geodynamics, Lithosphere, IHY, IPY and eGY. IYPE activities have concentrated in publications, OneGeology, radio/TV programs, organization of conferences, meetings and outreach events. A book series on Earth Science Experiments for Children has been edited, with first books published on “Atmospheric Pressure and Free Fall of Objects”, “Light and Colors”, “Standing on Archimedes”, “Foucault and Climate” and “Earth and its Waves “. Books are distributed to schools, with tens of thousand copies distributed nationwide and new editions underway. Other publications include leaflets, books and special El Faro issues (edited by the National University) and articles in other journals. In 2007 the AGU Joint Assembly with international participation from US, Canada, Europe and Latin America was held in Acapulco. Current plans include an electronic open-access journal, additional publications of the Planet Earth series, articles and special issues in journals and magazines, plus events on selected themes from the IYPE science program, particularly on Megacities, Hazards, Resources and Biodiversity. Mexico City metropolitan area, with > 22 million inhabitants presents special challenges, being at high altitude within an active tectonic and volcanic area requiring major efforts in water supply, water control, rains and waste disposal and management. Involvement in international activities includes OneGeology, translation into Spanish of IYPE thematic leaflets and participation in meetings and outreach activities. A major long-lasting legacy of IYPE is the formation of links/partnerships within Latin America and in the international context. Consolidating and expanding cooperation/partnership in research, education and outreach will then be our major challenges. In addition to future plans in different countries and regions, we consider that IYPE should develop long-term initiatives for enhancing international cooperation and ensuring increased effective use by society of the Earth and space sciences.

Introduction to the special issue: toward implementing physiological measures in clinical child and adolescent assessments.

PubMed

De Los Reyes, Andres; Aldao, Amelia

2015-01-01

The National Institute of Mental Health recently launched the Research Domain Criteria (RDoC). The RDoC is an initiative to improve classification of mental health concerns by promoting research on the brain mechanisms underlying these concerns, with the ultimate goal of developing interventions that target these brain mechanisms. A key focus of RDoC involves opening new lines of research examining patients' responses on biological measures. The RDoC presents unique challenges to mental health professionals who work with children and adolescents. Indeed, mental health professionals rarely integrate biological measures into clinical assessments. Thus, RDoC's ability to improve patient care rests, in part, on the development of strategies for implementing biological measures within mental health assessments. Further, mental health professionals already carry out comprehensive assessments that frequently yield inconsistent findings. These inconsistencies have historically posed challenges to interpreting research findings as well as assessment outcomes in practice settings. In this introductory article, we review key issues that informed the development of a special issue of articles demonstrating methods for implementing low-cost measures of physiological functioning in clinical child and adolescent assessments. We also outline a conceptual framework, informed by theoretical work on using and interpreting multiple informants' clinical reports (De Los Reyes, Thomas, Goodman, & Kundey, 2013 ), to guide hypothesis testing when using physiological measures within clinical child and adolescent assessments. This special issue and the conceptual model described in this article may open up new lines of research testing paradigms for implementing clinically feasible physiological measures in clinical child and adolescent assessments.

In the context of inclusive education, so-called «Schulbegleiter» (school escorts) have been installed to assist children with special needs. However, adequate conceptions of their role are lacking, and no provisions exist describing the exact tasks and duties of these school escorts. This article presents data on a statewide empirical study and provides information on the professional background, qualifications, and assignments of such escorts as well as the nature of the assisted children in the German state of Baden-Württemberg. The data were collected in nearly 50 % of all schools providing general education in Baden-Württemberg, and a total of 526 school escorts completed a questionnaire on their work. Children with special needs who received such assistance were aged 6 to 19 years (M = 10.4) and had a mental disorder in nearly three-fourths of all cases, with autism spectrum disorders being most common (59.4 %). The most frequent assignments of the escorts were providing practical assistance during classes and mobilizing the child as well as providing direct support in emotionally challenging situations. Such escorts can make a significant contribution to the inclusive education of disabled children. They do, however, need an adequate qualification and practical competences to meet the diverse challenges of children with special needs. Child and adolescent psychiatrists are supposed to stay involved in the process, not only by planning interventions, but also during the course of inclusive education itself. Thus, the emotional situation and adjustment of included children with mental disorders over time must be monitored adequately.

Induction of labor in resource-limited settings has the potential to significantly improve health outcomes for both mothers and infants. However, there are relatively little context-specific data to guide practice, and few specific guidelines. Also, there may be considerable issues regarding the facilities and organizational capacities necessary to support safe practices in many aspects of obstetrical practice, and for induction of labor in particular. Herein we describe the various opportunities as well as challenges presented by induction of labor in these settings. Copyright © 2015 Elsevier Inc. All rights reserved.

The frontal sinus is the most complex of all paranasal sinuses. Given its proximity to the cranial vault and orbit, frontal sinus pathology can progress to involve these structures and lead to significant morbidity, or even mortality. Surgical management of the frontal sinus is technically challenging. Various open and endoscopic surgical techniques are available to the otolaryngologist. This article presents an overview of the major disease entities that affect the frontal sinus, with a special emphasis on treatment principles and surgical management. Copyright © 2016 Elsevier Inc.

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.

The high-resolution and coupled forecasting of wind, waves and currents, in restricted coastal domains, offer a number of important challenges; these limit the quality of predictions, in the present state-of-the-art. This paper presents the main results obtained for such coastal domains, with reference to a variety of modelling suites and observing networks for: a) Liverpool Bay; b) German Bight; c) Gulf of Venice; and d) the Catalan coast. All of these areas are restricted domains, where boundary effects play a significant role in the resulting inner dynamics. This contribution addresses also the themes of the other papers in this Special Issue, ranging from observations to simulations. Emphasis is placed upon the physics controlling such restricted areas. The text deals also with the transfer to end-users and other interested parties, since the requirements on resolution, accuracy and robustness must be linked to their applications. Finally, some remarks are included on the way forward for coastal oceanography and the synergetic combination of in-situ and remote measurements, with high-resolution 3D simulations.

Primary breast tuberculosis: diagnostic and therapeutic dilemmas.

To review the diagnostic and therapeutic challenges associated with treating isolated primary breast tuberculosis through discussion of our series of seven cases. Although breast is an uncommon site of occurrence of tuberculosis and isolated primary breast tuberculosis is an even rarer entity, its importance lies in distinguishing it from more common pathologies like abscesses or malignancy and avoiding unnecessary erroneous surgical intervention. The spectrum and presentation is wide and varied and we present our experience in managing seven such cases. A retrospective analysis of all the cases of histopathologically proven primary breast tuberculosis in the last three years at M.S. Ramaiah Hospital (2012-2014) was done. Analysis was in terms of mode of presentation, clinical features, diagnostic modalities used for evaluation and confirmation of the diagnosis, medical treatment and surgical intervention, if any. Special emphasis was placed on dilemmas in diagnosis and difficulties encountered during treatment. All cases were followed up till cure. Patients most commonly presented with a breast abscess, painful breast lumps and recurrent abscesses. Other foci of tuberculosis were ruled out in all of these patients. Majority were treated exclusively with anti-tubercular therapy (although regimens varied), but those with abscesses underwent incision and drainage. All cases were treated and followed up till cure. The challenges associated with primary breast tuberculosis are multiple, including which anti-tubercular therapy regimen to use, when to surgically intervene (as the breast is a cosmetically important area) and treating atypical mycobacteria. We provide a detailed discussion of the challenges we faced and review of literature.

The history of transdisciplinary race classification: methods, politics and institutions, 1840s-1940s.

PubMed

McMahon, Richard

2018-03-01

A recently blossoming historiographical literature recognizes that physical anthropologists allied with scholars of diverse aspects of society and history to racially classify European peoples over a period of about a hundred years. They created three successive race classification coalitions - ethnology, from around 1840; anthropology, from the 1850s; and interwar raciology - each of which successively disintegrated. The present genealogical study argues that representing these coalitions as 'transdisciplinary' can enrich our understanding of challenges to disciplinary specialization. This is especially the case for the less well-studied nineteenth century, when disciplines and challenges to disciplinary specialization were both gradually emerging. Like Marxism or structuralism, race classification was a holistic interpretive framework, which, at its most ambitious, aimed to structure the human sciences as a whole. It resisted the organization of academia and knowledge into disciplines with separate organizational institutions and research practices. However, the 'transdisciplinarity' of this nationalistic project also bridged emerging borderlines between science and politics. I ascribe race classification's simultaneous longevity and instability to its complex and intricately entwined processes of political and interdisciplinary coalition building. Race classification's politically useful conclusions helped secure public support for institutionalizing the coalition's component disciplines. Institutionalization in turn stimulated disciplines to professionalize. They emphasized disciplinary boundaries and insisted on apolitical science, thus ultimately undermining the 'transdisciplinary' project.

Mathematical Learning Disabilities in Special Populations: Phenotypic Variation and Cross-Disorder Comparisons

What is mathematical learning disability (MLD)? The reviews in this special issue adopt different approaches to defining the construct of MLD. Collectively, they demonstrate the current status of efforts to establish a consensus definition and the challenges faced in this endeavor. In this commentary, we reflect upon the proposed pathways to mathematical learning difficulties and disabilities presented across the reviews. Specifically we consider how each of the reviews contributes to identifying the MLD phenotype by specifying the range of assets and deficits in mathematics, identifying sources of individual variation, and characterizing the natural progression of MLD over the life course. We show how principled comparisons across disorders address issues about the cognitive and behavioral co-morbidities of MLD, and whether commonalities in brain dysmorphology are associated with common mathematics performance profiles. We project the status of MLD research ten years hence with respect to theoretical gains, advances in methodology, and principled intervention studies. PMID:19213019

Low aqueous solubility of active pharmaceutical ingredients presents a serious challenge in the development process of new drug products. This article provides an overview on some of the current approaches for the formulation of poorly water-soluble drugs with a special focus on strategies pursued at the Center of Pharmaceutical Engineering of the TU Braunschweig. These comprise formulation in lipid-based colloidal drug delivery systems and experimental as well as computational approaches towards the efficient identification of the most suitable carrier systems. For less lipophilic substances the preparation of drug nanoparticles by milling and precipitation is investigated for instance by means of microsystem-based manufacturing techniques and with special regard to the preparation of individualized dosage forms. Another option to overcome issues with poor drug solubility is the incorporation into nanospun fibers. Copyright © 2017 Elsevier B.V. All rights reserved.

Privacy, Security, and Patient Engagement: The Changing Health Data Governance Landscape.

Holmes, John H

2016-01-01

The rapid emergence of new technologies support collection and use of a wide variety of data from clinical, genomic, social and behavioral, environmental, and financial sources, and have a great impact on the governance of personal health information. The papers in this special issue on governance touch on the topic from a variety of focuses, including leadership perspectives, local and federal case studies, and the future importance of patient engagement. This special issue focuses on three major themes-that data governance is growing in importance and presenting new challenges that must be addressed, that health care organizations must prioritize governance design, implementation, and functions as a priority, and that governance seems to be naturally converging on an archetype as described by this set of papers. In order to deal with issues such as data de- and re-identification, data governance must be studied as its own field.

Autonomous robotic assembly by mobile field robots has seen significant advances in recent decades, yet practicality remains elusive. Identified challenges include better use of state estimation to and reasoning with uncertainty, spreading out tasks to specialized robots, and implementing representative joining methods. This paper proposes replacing 1) self-correcting mechanical linkages with generalized joints for improved applicability, 2) assembly serial manipulators with parallel manipulators for higher precision and stability, and 3) all-in-one robots with a heterogeneous team of specialized robots for agent simplicity. This paper then describes a general assembly algorithm utilizing state estimation. Finally, these concepts are tested in the context of solar array assembly, requiring a team of robots to assemble, bond, and deploy a set of solar panel mockups to a backbone truss to an accuracy not built into the parts. This paper presents the results of these tests.

Women who inject drugs require gender-specific approaches to drug rehabilitation, modification of risk behaviors, and psychosocial adaptation. Improved outcomes have been demonstrated when the specific needs of women's subpopulations have been addressed. Special services for women include prenatal care, child care, women-only programs, supplemental workshops on women-focused topics, mental health services, and comprehensive programs that include several of the above components. To address the special needs of women injecting drug user (IDU) subpopulations, such as HIV-positive pregnant women and women with young children, recently released female prisoners, and street-involved girls and young women, HealthRight International and its local partners in Russia and Ukraine have developed innovative service models. This paper presents each of these models and discusses their effectiveness and implementation challenges specific to local contexts in Russia and Ukraine. PMID:23304535

The reader might get the impression that the four projects described in this Special Section proceeded in a systematic and predictable way. Of course, those of us engaged in each research project encountered pitfalls and challenges along the way. A main goal of this Special Section is to provide pathways and encouragement for those who may be interested in advancing high-quality research on this topic. In this paper, we describe a set of practical and ethical challenges that we encountered in conducting our longitudinal, process-oriented, and translational research with conflict-affected youth, and we illustrate how problems can be solved with the goal of maintaining the internal and external validity of the research designs. We are hopeful that by describing the challenges of our work, and how we overcame them, which are seldom treated in this or any other literature on research on child development in high-risk contexts, we can offer a realistic and encouraging picture of conducting methodologically sound research in conflict-affected contexts.

[Comparing students in inclusive education to those in special schools: the view of parents of children with learning disabilities].

Klicpera, Christian; Klicpera, Barbara Gasteiger

2004-12-01

The paper presents the results of a survey of 755 parents of learning disabled children with certified special needs who either attended classes within regular education or special schools. All parents were involved in the decision on the school placement of their children. The experiences of 547 parents of learning disabled students in inclusive classes were contrasted with those of 207 parents of children in special schools. Besides a rather high satisfaction with previous school experiences of their children a number of differences between the two groups of parents could be observed. Parents of students in special schools viewed their children as rather little challenged by their educational requirements whereas those in inclusive education found their children to be overtaxed. The social development of the students in inclusive education was judged as more positive and, generally, a higher rate of parents of learning disabled students in inclusive classes were satisfied with their choice of the educational setting. Although the requirements for parental support concerning studying were higher in inclusive classes this cannot solely explain the differences of experiences with school. In a second step, satisfied parents were compared to dissatisfied parents. It could be found that the group of dissatisfied parents had to make their choice on the educational setting of their children under less favourable conditions and many could not accept that their child had been classified as having special needs. This applied to parents of students in inclusive education as well as to parents of children in special schools. Additionally, parents of students with German as a second language reported to be discontented more frequently. No significant discrepancies could be found between different grades or federal states with different quotas of inclusive education.

Derived from the bacterial adaptive immune system, CRISPR technology has revolutionized conventional genetic engineering methods and unprecedentedly facilitated strain engineering. In this review, we outline the fundamental CRISPR tools that have been employed for strain optimization. These tools include CRISPR editing, CRISPR interference, CRISPR activation and protein imaging. To further characterize the CRISPR technology, we present current applications of these tools in microbial systems, including model- and non-model industrial microorganisms. Specially, we point out the major challenges of the CRISPR tools when utilized for multiplex genome editing and sophisticated expression regulation. To address these challenges, we came up with strategies that place emphasis on the amelioration of DNA repair efficiency through CRISPR-Cas9-assisted recombineering. Lastly, multiple promising research directions were proposed, mainly focusing on CRISPR-based construction of microbial ecosystems toward high production of desired chemicals.

Astrometry with LSST: Objectives and Challenges

The forthcoming Large Synoptic Survey Telescope (LSST) is an optical telescope with an effective aperture of 6.4 m, and a field of view of 9.6 square degrees. Thus, LSST will have an étendue larger than any other optical telescope, performing wide-field, deep imaging of the sky. There are four broad categories of science objectives: 1) dark-energy and dark matter, 2) transients, 3) the Milky Way and its neighbours and, 4) the Solar System. In particular, for the Milky-Way science case, astrometry will make a critical contribution; therefore, special attention must be devoted to extract the maximum amount of astrometric information from the LSST data. Here, we outline the astrometric challenges posed by such a massive survey. We also present some current examples of ground-based, wide-field, deep imagers used for astrometry, as precursors of the LSST.

Head and neck cancers pose an especially serious problem in developing countries due to late presentation requiring complex surgical intervention. These countries are faced with many challenges, ranging from insufficient health care staff to problems with peri-operative requirements, diagnostic facilities, chemoradiation services and research funding.These challenges can be addressed through the training of head and neck surgeons and support personnel, the improvement of cancer awareness in local communities, and the establishment of dedicated head and neck institutes which focus on the special needs of head and neck cancer patients.All these changes can best be achieved through collaborative efforts with external partners. The Karl Storz Fellowship in Advanced Head and Neck Cancer, enabling training at the University of Cape Town, South Africa, has served as a springboard towards establishing head and neck services in developing sub-Saharan African countries.

Payne, Amanda N; Zihler, Annina; Chassard, Christophe; Lacroix, Christophe

2012-01-01

The gut microbiota is a highly specialized organ containing host-specific assemblages of microbes whereby metabolic activity directly impacts human health and disease. In vitro gut fermentation models present an unmatched opportunity of performing studies frequently challenged in humans and animals owing to ethical concerns. Multidisciplinary systems biology analyses supported by '-omics' platforms remain widely neglected in the field of in vitro gut fermentation modeling but are key to advancing the significance of these models. Model-driven experimentation using a combination of in vitro gut fermentation and in vitro human cell models represent an advanced approach in identifying complex host-microbe interactions and niches central to gut fermentation processes. The aim of this review is to highlight the advances and challenges exhibited by in vitro human gut fermentation modeling. Copyright © 2011 Elsevier Ltd. All rights reserved.

Unraveling snake venom complexity with 'omics' approaches: challenges and perspectives.

PubMed

Zelanis, André; Tashima, Alexandre Keiji

2014-09-01

The study of snake venom proteomes (venomics) has been experiencing a burst of reports, however the comprehensive knowledge of the dynamic range of proteins present within a single venom, the set of post-translational modifications (PTMs) as well as the lack of a comprehensive database related to venom proteins are among the main challenges in venomics research. The phenotypic plasticity in snake venom proteomes together with their inherent toxin proteoform diversity, points out to the use of integrative analysis in order to better understand their actual complexity. In this regard, such a systems venomics task should encompass the integration of data from transcriptomic and proteomic studies (specially the venom gland proteome), the identification of biological PTMs, and the estimation of artifactual proteomes and peptidomes generated by sample handling procedures.

McDonald, J Douglas

2017-08-01

Indigenous Americans (i.e., Native/American Indians, AK natives, Pacific Islanders) have consistently volunteered for military service at greater rates than any other ethnic group, including the majority culture, since the early days of the country. This article is an introduction to the special section which includes a number of outstanding papers that provide an innovative and compelling effort to overcome the challenges of casualties from war and render effective and culturally informed care. These manuscripts describe culturally appropriate considerations of suicide (O'Keefe), family involvement and access to care (Whealin), and telehealth for treatment of rural Native veterans (Goss). Challenging and complex treatment needs call for equally mindful and competent approaches. These authors and providers present compelling examples of addressing these needs in working with our Wounded Warriors. (PsycINFO Database Record (c) 2017 APA, all rights reserved).

The Role of a Multidimensional Concept of Trust in the Performance of Global Virtual Teams

NASA Technical Reports Server (NTRS)

Bodensteiner, Nan Muir; Stecklein, Jonette M.

2002-01-01

This paper focuses on the concept of trust as an important ingredient of effective global virtual team performance. Definitions of trust and virtual teams are presented. The concept of trust is developed from its unilateral application (trust, absence of trust) to a multidimensional concept including cognitive and affective components. The special challenges of a virtual team are then discussed with particular emphasis on how a multidimensional concept of trust impacts these challenges. Propositions suggesting the multidimensional concept of trust moderates the negative impacts of distance, cross cultural and organizational differences, the effects of electronically mediated communication, reluctance to share information and a lack of hi story/future on the performance of virtual teams are stated. The paper concludes with recommendations and a set of techniques to build both cognitive and affective trust in virtual teams.

Intelligence in the brain: a theory of how it works and how to build it.

PubMed

Werbos, Paul J

2009-04-01

This paper presents a theory of how general-purpose learning-based intelligence is achieved in the mammal brain, and how we can replicate it. It reviews four generations of ever more powerful general-purpose learning designs in Adaptive, Approximate Dynamic Programming (ADP), which includes reinforcement learning as a special case. It reviews empirical results which fit the theory, and suggests important new directions for research, within the scope of NSF's recent initiative on Cognitive Optimization and Prediction. The appendices suggest possible connections to the realms of human subjective experience, comparative cognitive neuroscience, and new challenges in electric power. The major challenge before us today in mathematical neural networks is to replicate the "mouse level", but the paper does contain a few thoughts about building, understanding and nourishing levels of general intelligence beyond the mouse.

Introduction to the Special Series: Current Directions for Measuring Parenting Constructs to Inform Prevention Science.

PubMed

Lindhiem, Oliver; Shaffer, Anne

2017-04-01

Parenting behaviors are multifaceted and dynamic and therefore challenging to quantify. Measurement methods have critical implications for study results, particularly for prevention trials designed to modify parenting behaviors. Although multiple approaches can complement one another and contribute to a more complete understanding of prevention trials, the assumptions and implications of each approach are not always clearly addressed. Greater attention to the measurement of complex constructs such as parenting is needed to advance the field of prevention science. This series examines the challenges of measuring changes in parenting behaviors in the context of prevention trials. All manuscripts in the special series address measurement issues and make practical recommendations for prevention researchers. Manuscripts in this special series include (1) empirical studies that demonstrate novel measurement approaches, (2) re-analyses of prevention trial outcome data directly comparing and contrasting two or more methods, and (3) a statistical primer and practical guide to analyzing proportion data.

Where the Ocean Meets the Girl Guides, Exploring the Interface Between Teaching Science and Using Specialized Programs to Engage Girls in Ocean Literacy

NASA Astrophysics Data System (ADS)

Pelz, M. S.; Ewing, N.; Davidson, E.; Hoeberechts, M.

2016-02-01

This presentation focuses on Ocean Aware, a joint project between Ocean Networks Canada (ONC) and the British Columbia Girl Guides Canada (Girl Guides). On World Oceans Day 2014, Girl Guides launched a new challenge to its members: "Are you Ocean Aware?" To answer this question, girls of any age can now earn their Ocean Aware Challenge crest. Ocean Networks Canada (ONC), an initiative of the University of Victoria, operates cabled ocean observatories which supply continuous power and Internet connectivity to a broad suite of subsea instruments from the coast to the deep sea. This Internet connectivity permits researchers, students and members of the public to download freely available data on their computers anywhere around the globe, in near real-time. Girl Guides provides a safe, all-girl environment that invites girls to challenge themselves, to find their voice, meet new friends, have fun and make a difference in the world. Girl Guides strives to ensure that girls and women from all walks of life, identities and lived experiences feel a sense of belonging and can fully participate. Girl Guides of Canada is a member of the World Association of Girl Guides and Girl Scouts. Through a partnership between ONC and Girl Guides, Ocean Aware was created to promote ocean literacy and ocean technology to thousands of Guiders in British Columbia and beyond. One of the most interesting challenges was to present STEM learning outcomes in such a way that they are accessible to girls, facilitators, and communities that are both on the coast and inland. With a creative eye to the preforming arts, hands-on experiments, interactive experiences and games, this challenge successfully brings the 7 Principles of Ocean Literacy to any girl, in any community. In this presentation we will share some of the strategies, challenges and impacts of creating a successful program that engages a large audience in ocean science through a novel partnership.

Challenges Facing Children with Special Healthcare Needs and Their Families: Telemedicine as a Bridge to Care.

PubMed

Hooshmand, Mary; Yao, Kristiana

2017-01-01

Telemedicine is an increasingly utilized mode of healthcare delivery, which improves access to care for vulnerable populations. Children with Special Healthcare Needs (CSHCN) and their families face significant challenges, such as geographic, financial, and sociocultural barriers, in accessing needed healthcare services. The literature supports telemedicine as an effective accepted bridge between CSHCN and their providers. A growing body of telemedicine projects also suggests cost-effectiveness when considering the direct and indirect costs the families of CSCHN incur in seeking healthcare services. These new systems of care should prioritize caring and family centeredness while reducing the burdens of CSHCN and their families.

Turning from organization-centric to process-controlled or even to personalized approaches, advanced healthcare settings have to meet special interoperability challenges. eHealth and pHealth solutions must assure interoperability between actors cooperating to achieve common business objectives. Hereby, the interoperability chain also includes individually tailored technical systems, but also sensors and actuators. For enabling corresponding pervasive computing and even autonomic computing, individualized systems have to be based on an architecture framework covering many domains, scientifically managed by specialized disciplines using their specific ontologies in a formalized way. Therefore, interoperability has to advance from a communication protocol to an architecture-centric approach mastering ontology coordination challenges.

Challenges that nurses face in caring for morbidly obese patients in the acute care setting.

Drake, Daniel; Dutton, Kathy; Engelke, Martha; McAuliffe, Maura; Rose, Mary Ann

2005-01-01

Despite increasing numbers of morbidly obese patients admitted to acute care facilities for surgery or treatment of nonsurgical conditions, there is little evidence of the problems nurses face in providing care to these patients. Anecdotal evidence suggests that the care of these patients is more demanding than the care of nonobese patients. The objective of this study was to describe nurses' perceptions of the challenges that they face when caring for morbidly obese patients. Focus groups of nurses from a tertiary care facility were convened. A trained facilitator posed questions to the group concerning various aspects of care for morbidly obese patients. Comments of respondents were categorized using NVIVO software. Nurses reported concerns about the increased staffing needs required for care of these patients and the particular challenges of the physical care. Concerns also included the availability, placement, and use of specialized equipment. Room size and the absence of some equipment were also problematic. Finally, nurses perceived safety issues, both for themselves and their patients. Morbidly obese patients in the acute care setting require specialized nursing care in terms of techniques, levels of staffing required, and the use of specialized equipment.

Variable Emissivity Through MEMS Technology

NASA Technical Reports Server (NTRS)

Darrin, Ann Garrison; Osiander, Robert; Champion, John; Swanson, Ted; Douglas, Donya; Grob, Lisa M.; Powers, Edward I. (Technical Monitor)

2000-01-01

This paper discusses a new technology for variable emissivity (vari-e) radiator surfaces, which has significant advantages over traditional radiators and promises an alternative design technique for future spacecraft thermal control systems. All spacecraft rely on radiative surfaces to dissipate waste heat. These radiators have special coatings, typically with a low solar absorptivity and a high infrared-red emissivity, that are intended to optimize performance under the expected heat load and thermal sink environment. The dynamics of the heat loads and thermal environment make it a challenge to properly size the radiator and often require some means of regulating the heat rejection rate of the radiators in order to achieve proper thermal balance. Specialized thermal control coatings, which can passively or actively adjust their emissivity offer an attractive solution to these design challenges. Such systems would allow intelligent control of the rate of heat loss from a radiator in response to heat load and thermal environmental variations. Intelligent thermal control through variable emissivity systems is well suited for nano and pico spacecraft applications where large thermal fluctuations are expected due to the small thermal mass and limited electric resources. Presently there are three different types of vari-e technologies under development: Micro ElectroMechanical Systems (MEMS) louvers, Electrochromic devices, and Electrophoretic devices. This paper will describe several prototypes of micromachined (MEMS) louvers and experimental results for the emissivity variations measured on theses prototypes. It will further discuss possible actuation mechanisms and space reliability aspects for different designs. Finally, for comparison parametric evaluations of the thermal performances of the new vari-e technology and standard thermal control systems are presented in this paper.

PubMed

Gibson, Carri-Ann

2012-01-01

With the large number of Veterans experiencing posttraumatic stress disorder (PTSD) and chronic pain, the purpose of this article is to review the prevalence of PTSD and chronic pain, the theoretical models that explain the maintenance of both conditions, and the challenges faced by providers and families who care for these patients. The Department of Veterans Affairs (VA)/Department of Defense (DOD) VA/DOD Clinical Practice Guideline for Management of Post-Traumatic Stress with special attention to chronic pain is presented. Limited scientific evidence supports specific care and treatment of PTSD and chronic pain, and this challenges providers to investigate and research potential treatment options. Integrated care models designed for working with these patients are reviewed, including a focus on the techniques and strategies to address not only PTSD and chronic pain, but other conditions, including substance dependence and depression. A specific focus on headaches, back pain, and neuropathic pain follows, including treatment recommendations such as pharmacological, psychotherapeutic, and complementary approaches, given the high rates of these pain complaints for Veterans in PTSD clinical programs. Integrated care is presented as a viable solution and approach that challenges clinicians and researchers to develop innovative, scientifically based therapeutics and treatments to enhance the recovery and quality of life for Veterans with PTSD and chronic pain.

Electromigrative separation techniques in forensic science: combining selectivity, sensitivity, and robustness.

PubMed

Posch, Tjorben Nils; Pütz, Michael; Martin, Nathalie; Huhn, Carolin

2015-01-01

In this review we introduce the advantages and limitations of electromigrative separation techniques in forensic toxicology. We thus present a summary of illustrative studies and our own experience in the field together with established methods from the German Federal Criminal Police Office rather than a complete survey. We focus on the analytical aspects of analytes' physicochemical characteristics (e.g. polarity, stereoisomers) and analytical challenges including matrix tolerance, separation from compounds present in large excess, sample volumes, and orthogonality. For these aspects we want to reveal the specific advantages over more traditional methods. Both detailed studies and profiling and screening studies are taken into account. Care was taken to nearly exclusively document well-validated methods outstanding for the analytical challenge discussed. Special attention was paid to aspects exclusive to electromigrative separation techniques, including the use of the mobility axis, the potential for on-site instrumentation, and the capillary format for immunoassays. The review concludes with an introductory guide to method development for different separation modes, presenting typical buffer systems as starting points for different analyte classes. The objective of this review is to provide an orientation for users in separation science considering using capillary electrophoresis in their laboratory in the future.
