Kuziemsky, Craig E; Borycki, Elizabeth M; Kushniruk, Andre W

2016-01-01

The design and implementation of health information technology (HIT) is challenging, particularly when it is being introduced into complex settings. While complex adaptive system (CASs) can be a valuable means of understanding relationships between users, HIT and tasks, much of the existing work using CASs is descriptive in nature. This paper addresses that issue by integrating a model for analyzing task complexity with approaches for HIT evaluation and systems analysis. The resulting framework classifies HIT-user tasks and issues as simple, complicated or complex, and provides insight on how to study them.

Injury prevention in Australian Indigenous communities.

PubMed

Ivers, Rebecca; Clapham, Kathleen; Senserrick, Teresa; Lyford, Marilyn; Stevenson, Mark

2008-12-01

Injury prevention in Indigenous communities in Australia is a continuing national challenge, with Indigenous fatality rates due to injury three times higher than the general population. Suicide and transport are the leading causes of injury mortality, and assault, transport and falls the primary causes of injury morbidity. Addressing the complex range of injury problems in disadvantaged Indigenous communities requires considerable work in building or enhancing existing capacity of communities to address local safety issues. Poor data, lack of funding and absence of targeted programs are some of the issues that impede injury prevention activities. Traditional approaches to injury prevention can be used to highlight key areas of need, however adaptations are needed in keeping with Indigenous peoples' holistic approach to health, linked to land and linked to community in order to address the complex spiritual, emotional and social determinants of Indigenous injury.

Socio-Technical Considerations for the Use of Blockchain Technology in Healthcare.

PubMed

Wong, Ming Chao; Yee, Kwang Chien; Nøhr, Christian

2018-01-01

Blockchain technology is often considered as the fourth industrial revolution that will change the world. The enthusiasm of the transformative nature of blockchain technology has infiltrated healthcare. Blockchain is often seen as the much needed and perfect technology for healthcare, addressing the difficult and complex issues of security and inter-operability. More importantly, the "value" and trust-based system can deliver automated action and response via its smart contract mechanism. Healthcare, however, is a complex system. Health information technology (HIT) so far, has not delivered its promise of transforming healthcare due to its complex socio-technical and context sensitive interaction. The introduction of blockchain technology will need to consider a whole range of socio-technical issues in order to improve the quality and safety of patient care. This paper presents a discussion on these socio-technical issues. More importantly, this paper argues that in order to achieve the best outcome from blockchain technology, there is a need to consider a clinical transformation from "information" to "value " and trust. This paper argues that urgent research is needed to address these socio-technical issues in order to facilitate best outcomes for blockchain in healthcare. These socio-technical issues must then be further evaluated by means of working prototypes in the medical domain in coming years.

2013-01-01

In the genomic age, the challenges presented by various inherited conditions present a compelling argument for an interdisciplinary model of care. Cardiac arrhythmias with a genetic basis, such as long QT syndrome, require clinicians with expertise in many specialties to address the complex genetic, psychological, ethical and medical issues involved in treatment. The Montefiore-Einstein Center for CardioGenetics has been established to provide personalized, interdisciplinary care for families with a history of sudden cardiac death or an acute cardiac event. Four vignettes of patient care are presented to illustrate the unique capacity of an interdisciplinary model to address genetic, psychological, ethical and medical issues. Because interdisciplinary clinics facilitate collaboration among multiple specialties, they allow for individualized, comprehensive care to be delivered to families who experience complex inherited medical conditions. As the genetic basis of many complex conditions is discovered, the advantages of an interdisciplinary approach for delivering personalized medicine will become more evident.

Systems Engineering and Integration for Advanced Life Support System and HST

NASA Technical Reports Server (NTRS)

Kamarani, Ali K.

2005-01-01

Systems engineering (SE) discipline has revolutionized the way engineers and managers think about solving issues related to design of complex systems: With continued development of state-of-the-art technologies, systems are becoming more complex and therefore, a systematic approach is essential to control and manage their integrated design and development. This complexity is driven from integration issues. In this case, subsystems must interact with one another in order to achieve integration objectives, and also achieve the overall system's required performance. Systems engineering process addresses these issues at multiple levels. It is a technology and management process dedicated to controlling all aspects of system life cycle to assure integration at all levels. The Advanced Integration Matrix (AIM) project serves as the systems engineering and integration function for the Human Support Technology (HST) program. AIM provides means for integrated test facilities and personnel for performance trade studies, analyses, integrated models, test results, and validated requirements of the integration of HST. The goal of AIM is to address systems-level integration issues for exploration missions. It will use an incremental systems integration approach to yield technologies, baselines for further development, and possible breakthrough concepts in the areas of technological and organizational interfaces, total information flow, system wide controls, technical synergism, mission operations protocols and procedures, and human-machine interfaces.

Intersectoral action for health equity as it relates to climate change in Canada: contributions from critical systems heuristics.

PubMed

Buse, Chris

2013-12-01

Intersectoral action (ISA) has been at the forefront of public health policy discussions since the 1970s. ISA incorporates a broader perspective of public health issues and coordinates efforts to address the social, political, economic and environmental contexts from which health determinants operate and are created. Despite being forwarded as a useful way to address and treat complex or 'wicked' problems, such policy issues are still often addressed within, rather than across, disciplinary silos and ISA has been documented to fail more often than it succeeds. This paper contributes to an understanding of ISA by outlining and applying critical systems heuristics (CSH) theory and methods. CSH theory and methods are described and discussed before applying them to the example of addressing climate change and health equity through public health practice. CSH thinking provides useful tools to engage stakeholders, question relations of power that may exist between collaborating partners, and move beyond power inequalities that guide ISA initiatives. CSH is a compelling framing that can improve an understanding of the collaborative relationships that are a prerequisite for engaging in ISA to address complex or 'wicked' policy problems such as climate change. © 2013 John Wiley & Sons Ltd.

Rebecca

2017-01-01

Ecologists who specialize in translational ecology (TE) seek to link ecological knowledge to decision making by integrating ecological science with the full complement of social dimensions that underlie today's complex environmental issues. TE is motivated by a search for outcomes that directly serve the needs of natural resource managers and decision makers. This objective distinguishes it from both basic and applied ecological research and, as a practice, it deliberately extends research beyond theory or opportunistic applications. TE is uniquely positioned to address complex issues through interdisciplinary team approaches and integrated scientist–practitioner partnerships. The creativity and context‐specific knowledge of resource managers, practitioners, and decision makers inform and enrich the scientific process and help shape use‐driven, actionable science. Moreover, addressing research questions that arise from on‐the‐ground management issues – as opposed to the top‐down or expert‐oriented perspectives of traditional science – can foster the high levels of trust and commitment that are critical for long‐term, sustained engagement between partners.

Ergonomics and sustainability: towards an embrace of complexity and emergence.

PubMed

Dekker, Sidney W A; Hancock, Peter A; Wilkin, Peter

2013-01-01

Technology offers a promising route to a sustainable future, and ergonomics can serve a vital role. The argument of this article is that the lasting success of sustainability initiatives in ergonomics hinges on an examination of ergonomics' own epistemology and ethics. The epistemology of ergonomics is fundamentally empiricist and positivist. This places practical constraints on its ability to address important issues such as sustainability, emergence and complexity. The implicit ethical position of ergonomics is one of neutrality, and its positivist epistemology generally puts value-laden questions outside the parameters of what it sees as scientific practice. We argue, by contrast, that a discipline that deals with both technology and human beings cannot avoid engaging with questions of complexity and emergence and seeking innovative ways of addressing these issues. Ergonomics has largely modelled its research on a reductive science, studying parts and problems to fix. In sustainability efforts, this can lead to mere local adaptations with a negative effect on global sustainability. Ergonomics must consider quality of life globally, appreciating complexity and emergent effects of local relationships.

Identifying Basic Factors for Communal Prosperity - Space Technologies are Bridging this Gap

NASA Technical Reports Server (NTRS)

Habib, Shahid

2006-01-01

There are many aspects, which are important for maintaining environmentally clean and safe conditions for a healthy and economically self-sufficient community. This problem was somewhat of a lesser concern in earlier days because many communities were small, isolated and solely dependent upon their owners or landlords. Due to an astronomical growth in human population within the last century, extensive use of combustion technologies, and changing environmental conditions has resulted in scarcity of natural resources. In reality, the societal sustainability issues are becoming much more acute and complex. Therefore, the researchers and social scientists are joining forces to address these topics and find solutions to many contentious areas such as public health and diseases, water resources, agriculture production, survivability during and after the natural disasters, energy needs and many others. Forthrightly speaking, there is no canned solution or a methodology to go about solving these issues since the magnitude and complexity of these issues are multi-dimensional and are further inter-locked with other areas. A common sense tells us that we need data, resources and technologies to begin addressing these problems. This is where space observations have provided us with tremendous information and opportunities, which are of great assets to the science, economist, and social scientists. This paper specifically addresses what are critical areas for a successful societal sustainability and growth; and how can we take advantage of multiple sensors and models already in existence. Increasing our knowledge of the home planet, via amplified set of observations, is certainly a right step in a right direction. Furthermore, this is a pre-requisite in understanding multiple hazard phenomena's. This paper further examines various space sensors and observing architectures that can be useful specifically in addressing some of these complex issues. The ultimate goal is to serve the society by providing such valuable information so the decision makers can take full advantage in making timely societal decisions.

Engineering education as a complex system

NASA Astrophysics Data System (ADS)

Gattie, David K.; Kellam, Nadia N.; Schramski, John R.; Walther, Joachim

2011-12-01

This paper presents a theoretical basis for cultivating engineering education as a complex system that will prepare students to think critically and make decisions with regard to poorly understood, ill-structured issues. Integral to this theoretical basis is a solution space construct developed and presented as a benchmark for evaluating problem-solving orientations that emerge within students' thinking as they progress through an engineering curriculum. It is proposed that the traditional engineering education model, while analytically rigorous, is characterised by properties that, although necessary, are insufficient for preparing students to address complex issues of the twenty-first century. A Synthesis and Design Studio model for engineering education is proposed, which maintains the necessary rigor of analysis within a uniquely complex yet sufficiently structured learning environment.

This article presents clinical examples that allow a template to be developed for pronoun use in working with such patients. Whether the clinician uses biologically congruent names and pronouns may depend upon the patient's progress in adopting the cross gender role as well whether family or friends either know or accept such changes. In certain situations, such as meetings with family members, the therapist may address the patient with gender congruent names; whereas on other occasions use cross-gender pronouns or names.

2016-01-01

People living with complex regional pain syndrome (CRPS) experience frustration with the lack of knowledge and understanding of CRPS as a pain condition. We report on our attempt to address this issue. People living with CRPS taking part in a larger study were invited to co-construct a CRPS wiki page that addressed the areas in which they had experienced the most difficulty. A blank wiki page was set up for participants to populate with issues they felt needed to be raised and addressed. Participants failed to engage with the wiki technology. We modified our procedure and completed an inductive analysis of a sister-forum which participants were using as part of the larger study. Six issues of importance were identified. We used the discussion forum threads to populate the themes. Due to a continued lack of engagement with the wiki technology, the team decided to create a suite of leaflets which were piloted with delegates at a CRPS patient conference. Future work should be mindful of the extent to which patients are able and willing to share their experiences through such technology. Striking the balance between patient-endorsed and researcher-driven co-creation of such material is imperative.

Economic analyses to support decisions about HPV vaccination in low- and middle-income countries: a consensus report and guide for analysts.

PubMed

Jit, Mark; Levin, Carol; Brisson, Marc; Levin, Ann; Resch, Stephen; Berkhof, Johannes; Kim, Jane; Hutubessy, Raymond

2013-01-30

Low- and middle-income countries need to consider economic issues such as cost-effectiveness, affordability and sustainability before introducing a program for human papillomavirus (HPV) vaccination. However, many such countries lack the technical capacity and data to conduct their own analyses. Analysts informing policy decisions should address the following questions: 1) Is an economic analysis needed? 2) Should analyses address costs, epidemiological outcomes, or both? 3) If costs are considered, what sort of analysis is needed? 4) If outcomes are considered, what sort of model should be used? 5) How complex should the analysis be? 6) How should uncertainty be captured? 7) How should model results be communicated? Selecting the appropriate analysis is essential to ensure that all the important features of the decision problem are correctly represented, but that the analyses are not more complex than necessary. This report describes the consensus of an expert group convened by the World Health Organization, prioritizing key issues to be addressed when considering economic analyses to support HPV vaccine introduction in these countries.

Abraham Lincoln, psychotherapist to the nation: the use of metaphors.

PubMed

Leetz, K L

1997-01-01

Metaphors are widely utilized in psychotherapy to effect change in patients. Psychotherapeutic metaphors, in their various versions, may offer new choices and ways of viewing oneself to the patient which are more palatable than straight discussions or sterile insights. By addressing resistances indirectly, metaphors can be an effective tool for the therapist to use, regardless of theoretical orientation. Abraham Lincoln, a master of metaphor, utilized this tool effectively in dealing with crises and the ultimate fragmentation, disunion of the national identity. The author argues that Lincoln was able to address complex issues (such as slavery, liberty, nationhood, union, and conduct of the war) with metaphors, much as a skilled psychotherapist addresses complex issues within his or her purview. Abraham Lincoln effectively disarmed his critics, established a means of communication with the people, and sought to make his points in an understandable nonconfrontational fashion. These are skills highly valued by psychotherapists. One might say that Abraham Lincoln conducted psychotherapy on a national scale. Without formal training, he was ultimately able to create a new and more stable sense of national self using a metaphorical approach.

Rare kidney diseases encompass at least 150 different conditions, most of which are inherited. Although individual rare kidney diseases raise specific issues, as a group these rare diseases can have overlapping challenges in diagnosis and treatment. These challenges include small numbers of affected patients, unidentified causes of disease, lack of biomarkers for monitoring disease progression, and need for complex care. To address common clinical and patient issues among rare kidney diseases, the KDIGO Controversies Conference entitled, Common Elements in Rare Kidney Diseases, brought together a panel of multidisciplinary clinical providers and patient advocates to address five central issues for rare kidney diseases. These issues encompassed diagnostic challenges, management of kidney functional decline and progression of chronic kidney disease, challenges in clinical study design, translation of advances in research to clinical care, and provision of practical and integrated patient support. Thus, by a process of consensus, guidance for addressing these challenges was developed and is presented here. Copyright © 2017 International Society of Nephrology. Published by Elsevier Inc.

Improved assemblies using a source-agnostic pipeline for MetaGenomic Assembly by Merging (MeGAMerge) of contigs

DOE PAGES

Scholz, Matthew; Lo, Chien -Chi; Chain, Patrick S. G.

2014-10-01

Assembly of metagenomic samples is a very complex process, with algorithms designed to address sequencing platform-specific issues, (read length, data volume, and/or community complexity), while also faced with genomes that differ greatly in nucleotide compositional biases and in abundance. To address these issues, we have developed a post-assembly process: MetaGenomic Assembly by Merging (MeGAMerge). We compare this process to the performance of several assemblers, using both real, and in-silico generated samples of different community composition and complexity. MeGAMerge consistently outperforms individual assembly methods, producing larger contigs with an increased number of predicted genes, without replication of data. MeGAMerge contigs aremore » supported by read mapping and contig alignment data, when using synthetically-derived and real metagenomic data, as well as by gene prediction analyses and similarity searches. Ultimately, MeGAMerge is a flexible method that generates improved metagenome assemblies, with the ability to accommodate upcoming sequencing platforms, as well as present and future assembly algorithms.« less

Next gen perception and cognition: augmenting perception and enhancing cognition through mobile technologies

NASA Astrophysics Data System (ADS)

Goma, Sergio R.

2015-03-01

In current times, mobile technologies are ubiquitous and the complexity of problems is continuously increasing. In the context of advancement of engineering, we explore in this paper possible reasons that could cause a saturation in technology evolution - namely the ability of problem solving based on previous results and the ability of expressing solutions in a more efficient way, concluding that `thinking outside of brain' - as in solving engineering problems that are expressed in a virtual media due to their complexity - would benefit from mobile technology augmentation. This could be the necessary evolutionary step that would provide the efficiency required to solve new complex problems (addressing the `running out of time' issue) and remove the communication of results barrier (addressing the human `perception/expression imbalance' issue). Some consequences are discussed, as in this context the artificial intelligence becomes an automation tool aid instead of a necessary next evolutionary step. The paper concludes that research in modeling as problem solving aid and data visualization as perception aid augmented with mobile technologies could be the path to an evolutionary step in advancing engineering.

Critical issues in NASA information systems

NASA Technical Reports Server (NTRS)

1987-01-01

The National Aeronautics and Space Administration has developed a globally-distributed complex of earth resources data bases since LANDSAT 1 was launched in 1972. NASA envisages considerable growth in the number, extent, and complexity of such data bases, due to the improvements expected in its remote sensing data rates, and the increasingly multidisciplinary nature of its scientific investigations. Work already has begun on information systems to support multidisciplinary research activities based on data acquired by the space station complex and other space-based and terrestrial sources. In response to a request from NASA's former Associate Administrator for Space Science and Applications, the National Research Council convened a committee in June 1985 to identify the critical issues involving information systems support to space science and applications. The committee has suggested that OSSA address four major information systems issues; centralization of management functions, interoperability of user involvement in the planning and implementation of its programs, and technology.

Ethics of caring and professional roles.

PubMed

Paulsen, Jens Erik

2011-03-01

Normative discussions about modern health care often revolve around principles stating what must not be done or how to ration scarce resources in the name of justice. These are important discussions. However, in order to have an impact on clinical roles, ethical reflection must be able to describe and address the complexities and challenges of modern nursing and doctoring, and maybe even the patient role. A multi-principled approach, such as the one suggested by Beauchamp and Childress, can obviously address almost any such issue, but a great deal of translation is often required in order to address role-related issues. I shall here argue that an ethics of caring is better suited to grasping the big picture when the question is how to create value-informed clinical roles in an era of rapid development.

Some Spatial Politics of Queer-Feminist Research: Personal Reflections From the Field.

Misgav, Chen

2016-01-01

This article addresses methodological issues emerging from research conducted with Trans in the Center, an LGBT activist group in Tel Aviv, Israel. It addresses some complex issues related to the politics and ethics of applying queer and feminist methodology to qualitative research in a trans, queer, and feminist community space. The focus is on two issues: the researcher's positionality vis-à-vis the participants and selecting the appropriate methodology in relation to the characteristics of the group under study. Such issues demonstrate how queer and feminist principles are articulated and interwoven in geographical-spatial research in two different dimensions: in the research practice and methodology and in the practices and the spaces created by the activity of the researched group itself. I conclude with insights arising from the attempt to apply feminist and queer paradigms in both theory and research, and I call for their integration into geographical research.

Genes, race, and psychology in the genome era: an introduction.

PubMed

Anderson, Norman B; Nickerson, Kim J

2005-01-01

The mapping of the human genome has reawakened interest in the topic of race and genetics, especially the use of genetic technology to examine racial differences in complex outcomes such as health and intelligence. Advances in genomic research challenge psychology to address the myriad conceptual, methodological, and analytical issues associated with research on genetics and race. In addition, the field needs to understand the numerous social, ethical, legal, clinical, and policy implications of research in this arena. Addressing these issues should not only benefit psychology but could also serve to guide such thought in other fields, including molecular biology. The purpose of this special issue is to begin a discussion of this issue of race and genetics within the field of psychology. Several scholars who work in the fields of genetics, race, or related areas were invited to write (or had previously submitted) articles sharing their perspectives. (c) 2005 APA

Genetic Testing for Rare Cancer: The Wider Issues.

PubMed

Jacobs, Chris; Pichert, Gabriella

2016-01-01

Identification of a potential genetic susceptibility to cancer and confirmation of a pathogenic gene mutation raises a number of challenging issues for the patient with cancer, their relatives and the health professionals caring for them. The specific risks and management issues associated with rare cancer types have been addressed in the earlier chapters. This chapter considers the wider issues involved in genetic counselling and genetic testing for a genetic susceptibility to cancer for patients, families and health professionals. The first part of the chapter will present the issues raised by the current practice in genetic counselling and genetic testing for cancer susceptibility. The second part of the chapter will address some of the issues raised by the advances in genetic testing technology and the future opportunities provided by personalised medicine and targeted cancer therapy. Facilitating these developments requires closer integration of genomics into mainstream cancer care, challenging the existing paradigm of genetic medicine, adding additional layers of complexity to the risk assessment and management of cancer and presenting wider issues for patients, families, health professionals and clinical services.

2016-04-01

Current trends in health care research point to a shift from disciplinary models to interdisciplinary team-based mixed methods inquiry designs. This keynote address discusses the problems and prospects of creating vibrant mixed methods health care interdisciplinary research teams that can harness their potential synergy that holds the promise of addressing complex health care issues. We examine the range of factors and issues these types of research teams need to consider to facilitate efficient interdisciplinary mixed methods team-based research. It is argued that concepts such as disciplinary comfort zones, a lack of attention to team dynamics, and low levels of reflexivity among interdisciplinary team members can inhibit the effectiveness of a research team. This keynote suggests a set of effective strategies to address the issues that emanate from the new field of research inquiry known as team science as well as lessons learned from tapping into research on organizational dynamics. © The Author(s) 2016.

Young, Richard A; Burge, Sandy; Kumar, Kaparaboyna Ashok; Wilson, Jocelyn

2017-01-01

The purpose of this study was to characterize the content of family physician (FP) clinic encounters, and to count the number of visits in which the FPs addressed issues not explicitly reportable by 99211 to 99215 and 99354 Current Procedural Terminology (CPT) codes with current reimbursement methods and based on examples provided in the CPT manual. The data collection instrument was modeled on the National Ambulatory Medical Care Survey. Trained assistants directly observed every other FP-patient encounter and recorded every patient concern, issue addressed by the physician (including care barriers related to health care systems and social determinants), and treatment ordered in clinics affiliated with 10 residencies of the Residency Research Network of Texas. A visit was deemed to include physician work that was not explicitly reportable if the number or nature of issues addressed exceeded the definitions or examples for 99205/99215 or 99214 + 99354 or a preventive service code, included the physician addressing health care system or social determinant issues, or included the care of a family member. In 982 physician-patient encounters, patients raised 517 different reasons for visit (total, 5278; mean, 5.4 per visit; range, 1 to 16) and the FPs addressed 509 different issues (total issues, 3587; mean, 3.7 per visit; range, 1 to 10). FPs managed 425 different medications, 18 supplements, and 11 devices. A mean of 3.9 chronic medications were continued per visit (range, 0 to 21) and 4.6 total medications were managed (range, 0 to 22). In 592 (60.3%) of the visits the FPs did work that was not explicitly reportable with available CPT codes: 582 (59.3%) addressed more numerous issues than explicitly reportable, 64 (6.5%) addressed system barriers, and 13 (1.3%) addressed concerns for other family members. FPs perform cognitive work in a majority of their patient encounters that are not explicitly reportable, either by being higher than the CPT example number of diagnoses per code or the type of problems addressed, which has implications for the care of complex multi-morbid patients and the growth of the primary care workforce. To address these limitations, either the CPT codes and their associated rules should be updated to reflect the realities of family physicians' practices or new billing and coding approaches should be developed. © Copyright 2017 by the American Board of Family Medicine.

Interdisciplinary scientific knowledge is necessary but not sufficient when it comes to addressing sustainable transformations, as science increasingly has to deal with normative and value-related issues. A systems perspective on coupled human-environmental systems (HES) helps to address the inherent complexities. Additionally, a thorough interaction between science and society (i.e., transdisciplinarity = TD) is necessary, as sustainable transitions are sometimes contested and can cause conflicts. In order to navigate complexities regarding the delicate interaction of scientific research with societal decisions these processes must proceed in a structured and functional way. We thus propose HES-based TD processes to provide a basis for reorganizing science in coming decades.

Large system change challenges: addressing complex critical issues in linked physical and social domains

2015-04-01

Most action to address contemporary complex challenges, including the urgent issues of global sustainability, occurs piecemeal and without meaningful guidance from leading complex change knowledge and methods. The potential benefit of using such knowledge is greater efficacy of effort and investment. However, this knowledge and its associated tools and methods are under-utilized because understanding about them is low, fragmented between diverse knowledge traditions, and often requires shifts in mindsets and skills from expert-led to participant-based action. We have been engaged in diverse action-oriented research efforts in Large System Change for sustainability. For us, "large" systems can be characterized as large-scale systems - up to global - with many components, of many kinds (physical, biological, institutional, cultural/conceptual), operating at multiple levels, driven by multiple forces, and presenting major challenges for people involved. We see change of such systems as complex challenges, in contrast with simple or complicated problems, or chaotic situations. In other words, issues and sub-systems have unclear boundaries, interact with each other, and are often contradictory; dynamics are non-linear; issues are not "controllable", and "solutions" are "emergent" and often paradoxical. Since choices are opportunity-, power- and value-driven, these social, institutional and cultural factors need to be made explicit in any actionable theory of change. Our emerging network is sharing and building a knowledge base of experience, heuristics, and theories of change from multiple disciplines and practice domains. We will present our views on focal issues for the development of the field of large system change, which include processes of goal-setting and alignment; leverage of systemic transitions and transformation; and the role of choice in influencing critical change processes, when only some sub-systems or levels of the system behave in purposeful ways, while others are undeniably and unavoidably deterministic.

Pregnant African American women are at higher risk for multiple complex health issues, including depression, than their European American counterparts (Canady, Bullen, Holzman, Broman, & Tian, 2008; Martin et al, 2011; Mathews & MacDorman, 2007; Orr, Blazer, & James, 2006; Segre, Losch, & O'Hara, 2006). Various strategies must be used to address depression through preventive care and promotion of access to appropriate mental health services. Nurses and other health care providers need to examine the relationships between the multifactorial problems to improve the health and well-being of pregnant African American women and their unborn children. This article presents a case study demonstrating the use of complexity science theory to understand and prevent poor health outcomes for pregnant African American women with depression and their unborn children.

Complexities in understanding and addressing the serious public health issues related to the nonmedical use of prescription drugs

PubMed Central

Arria, Amelia M.; Compton, Wilson M.

2016-01-01

The nonmedical use of prescription drugs (NMUPD) is not only a serious public health problem, but also a complex one. The articles presented in this special issue underscore that complexity by describing multiple classes of prescription drugs (e.g., opioid analgesics, benzodiazepines, stimulants, anxiolytics, and sedatives) and examining multiple aspects of their patterns of use. Collectively, the articles examine epidemiologic use patterns in the United States, risk factors, clinical characteristics of individuals in treatment for dependence, and consequences. The key to addressing NMUPD is to construct a solid understanding of the issues through scientific research, and to translate the scientific evidence into action. The articles in this issue build upon a large body of literature that has accumulated during the last two decades. Dramatic increases in overdoses from prescription opioids and the transition to heroin use among nonmedical users of prescription opioids has captured the attention of community leaders across the nation. Yet, less well known is the co-occurrence of multiple substances among those using prescription drug nonmedically. This represents a common theme across these articles which document that nonmedical users were observed to have a history of using alcohol, marijuana, tobacco, and other psychoactive substances. In addition, the articles dispel certain ideas that appear to have gained traction in the popular discourse that have little scientific evidence behind them. First, the notion that prescription drug problems arise in cases of drug naïve individuals who are first exposed through a physician’s prescription for pain medication is widespread, but is not rooted in scientific evidence. Second, despite the popular notion that nonmedical use of stimulants confers an “academic edge”, nonmedical users have lower grade point averages (GPAs) than non-users. NMUPD was also shown to be associated with sexual aggression victimization and perpetration and regretted sex. In addition, several of the articles in this issue point to innovative targets for prevention of NMUPD. It is only through high-quality research can we gain a clearer understanding of the problem and how to address it. PMID:27639956

In the field of health technology assessment (HTA), there are several approaches that can be used for ethical analysis. However, there is a scarcity of literature that critically evaluates and compares the strength and weaknesses of these approaches when they are applied in practice. In this paper, we analyse the applicability of some selected approaches for addressing ethical issues in HTA in the field of complex health interventions. Complex health interventions have been the focus of methodological attention in HTA. However, the potential methodological challenges for ethical analysis are as yet unknown. Six of the most frequently described and applied ethical approaches in HTA were critically assessed against a set of five characteristics of complex health interventions: multiple and changing perspectives, indeterminate phenomena, uncertain causality, unpredictable outcomes, and ethical complexity. The assessments are based on literature and the authors' experiences of developing, applying and assessing the approaches. The Interactive, participatory HTA approach is by its nature and flexibility, applicable across most complexity characteristics. Wide Reflective Equilibrium is also flexible and its openness to different perspectives makes it better suited for complex health interventions than more rigid conventional approaches, such as Principlism and Casuistry. Approaches developed for HTA purposes are fairly applicable for complex health interventions, which one could expect because they include various ethical perspectives, such as the HTA Core Model® and the Socratic approach. This study shows how the applicability for addressing ethical issues in HTA of complex health interventions differs between the selected ethical approaches. Knowledge about these differences may be helpful when choosing and applying an approach for ethical analyses in HTA. We believe that the study contributes to increasing awareness and interest of the ethical aspects of complex health interventions in general.

Approximate l-fold cross-validation with Least Squares SVM and Kernel Ridge Regression

Edwards, Richard E; Zhang, Hao; Parker, Lynne Edwards

2013-01-01

Kernel methods have difficulties scaling to large modern data sets. The scalability issues are based on computational and memory requirements for working with a large matrix. These requirements have been addressed over the years by using low-rank kernel approximations or by improving the solvers scalability. However, Least Squares Support VectorMachines (LS-SVM), a popular SVM variant, and Kernel Ridge Regression still have several scalability issues. In particular, the O(n^3) computational complexity for solving a single model, and the overall computational complexity associated with tuning hyperparameters are still major problems. We address these problems by introducing an O(n log n) approximate l-foldmore » cross-validation method that uses a multi-level circulant matrix to approximate the kernel. In addition, we prove our algorithm s computational complexity and present empirical runtimes on data sets with approximately 1 million data points. We also validate our approximate method s effectiveness at selecting hyperparameters on real world and standard benchmark data sets. Lastly, we provide experimental results on using a multi-level circulant kernel approximation to solve LS-SVM problems with hyperparameters selected using our method.« less

Soliciting scientific information and beliefs in predictive modeling and adaptive management

NASA Astrophysics Data System (ADS)

Glynn, P. D.; Voinov, A. A.; Shapiro, C. D.

2015-12-01

Post-normal science requires public engagement and adaptive corrections in addressing issues with high complexity and uncertainty. An adaptive management framework is presented for the improved management of natural resources and environments through a public participation process. The framework solicits the gathering and transformation and/or modeling of scientific information but also explicitly solicits the expression of participant beliefs. Beliefs and information are compared, explicitly discussed for alignments or misalignments, and ultimately melded back together as a "knowledge" basis for making decisions. An effort is made to recognize the human or participant biases that may affect the information base and the potential decisions. In a separate step, an attempt is made to recognize and predict the potential "winners" and "losers" (perceived or real) of any decision or action. These "winners" and "losers" include present human communities with different spatial, demographic or socio-economic characteristics as well as more dispersed or more diffusely characterized regional or global communities. "Winners" and "losers" may also include future human communities as well as communities of other biotic species. As in any adaptive management framework, assessment of predictions, iterative follow-through and adaptation of policies or actions is essential, and commonly very difficult or impossible to achieve. Recognizing beforehand the limits of adaptive management is essential. More generally, knowledge of the behavioral and economic sciences and of ethics and sociology will be key to a successful implementation of this adaptive management framework. Knowledge of biogeophysical processes will also be essential, but by definition of the issues being addressed, will always be incomplete and highly uncertain. The human dimensions of the issues addressed and the participatory processes used carry their own complexities and uncertainties. Some ideas and principles are provided that may help guide and implement the proposed adaptive management framework and its public and stakeholder engagement processes. Examples and characteristics of issues that could be beneficially addressed through the proposed framework will also be presented.

Climate change is a pressing phenomenon with huge potential ethical, legal and social policy implications. Climate change gives rise to intricate moral and policy issues as it involves contested science, uncertainty and risk. In order to come to scientifically and morally justified, as well as feasible, policies, targeting climate change requires an interdisciplinary approach. This special issue will identify the main challenges that climate change poses from social, economic, methodological and ethical perspectives by focusing on the complex interrelations between uncertainty, values and policy in this context. This special issue brings together scholars from economics, social sciences and philosophy in order to address these challenges.

Research on fathering and the father-child relationship has made substantial progress in the most recent 15 years since the last special issue of the Infant Mental Health Journal on fathers and young children. This special issue on fathers and young children contains a series of papers exemplifying this progress, including advances in methodology-more direct assessment and more observational measures-in addition to the increasing dynamic complexity of the conceptual models used to study fathers, the diversity of fathers studied, and the growth of programs to support early father involvement. In assessing the current state of the field, special attention is given to contributions made by the papers contained in this special issue, and two critical areas for continued progress are addressed: (1) methodological and measurement development that specifically address fathers and fathering relationships and (2) cross-cultural and ecologically valid research examining the diversity of models of fathering. © 2014 Michigan Association for Infant Mental Health.

2016-01-01

Group model building (GMB) is an approach to building qualitative and quantitative models with stakeholders to learn about the interrelationships among multilevel factors causing complex public health problems over time. Scant literature exists on adapting this method to address public health issues that involve racial dynamics. This study's objectives are to (1) introduce GMB methods, (2) present a framework for adapting GMB to enhance cultural responsiveness, and (3) describe outcomes of adapting GMB to incorporate differences in racial socialization during a community project seeking to understand key determinants of community violence transmission. An academic-community partnership planned a 1-day session with diverse stakeholders to explore the issue of violence using GMB. We documented key questions inspired by critical race theory (CRT) and adaptations to established GMB "scripts" (i.e., published facilitation instructions). The theory's emphasis on experiential knowledge led to a narrative-based facilitation guide from which participants created causal loop diagrams. These early diagrams depict how violence is transmitted and how communities respond, based on participants' lived experiences and mental models of causation that grew to include factors associated with race. Participants found these methods useful for advancing difficult discussion. The resulting diagrams can be tested and expanded in future research, and will form the foundation for collaborative identification of solutions to build community resilience. GMB is a promising strategy that community partnerships should consider when addressing complex health issues; our experience adapting methods based on CRT is promising in its acceptability and early system insights.

2013-06-01

Integrating ethical issues in dementia-specific training material, clinical guidelines and national strategy plans requires an unbiased awareness of all the relevant ethical issues. To determine systematically and transparently the full spectrum of ethical issues in clinical dementia care. We conducted a systematic review in Medline (restricted to English and German literature published between 2000 and 2011) and Google books (with no restrictions). We applied qualitative text analysis and normative analysis to categorise the spectrum of ethical issues in clinical dementia care. The literature review retrieved 92 references that together mentioned a spectrum of 56 ethical issues in clinical dementia care. The spectrum was structured into seven major categories that consist of first- and second-order categories for ethical issues. The systematically derived spectrum of ethical issues in clinical dementia care presented in this paper can be used as training material for healthcare professionals, students and the public for raising awareness and understanding of the complexity of ethical issues in dementia care. It can also be used to identify ethical issues that should be addressed in dementia-specific training programmes, national strategy plans and clinical practice guidelines. Further research should evaluate whether this new genre of systematic reviews can be applied to the identification of ethical issues in other cognitive and somatic diseases. Also, the practical challenges in addressing ethical issues in training material, guidelines and policies need to be evaluated.

Struggles for Equal Rights and Social Justice as Unrepresented and Represented in Psychological Research.

2016-01-01

Issues of equality and social justice remain important concerns for contemporary societies. Struggles for equal rights and fair treatment continue in both organized movements and in acts of everyday life. We first consider trends in psychological research that fail to address such struggles and may even impede theoretical understanding of the complex processes of thought and action involved when individuals confront situations of welfare, justice, and rights. Then, we consider research, which attempts to address these issues. We review studies on the development of moral judgments and on understandings of equality and distributive justice. We also discuss research that accounts for the varying social contexts of individual lives and conceives of human behavior as engaged in moral judgments, which often produce resistance and opposition to injustice. In conclusion, we call for more attention in psychological research to issues of equity and social justice. © 2016 Elsevier Inc. All rights reserved.

HIV healthcare services in the USA are made available through a complex funding and delivery system. We present perspectives of HIV agencies on improvements that could lead to an ideal system of HIV prevention, treatment and care. We conducted semi-structured interviews with representatives from 21 HIV agencies offering diverse services in Baltimore, MD. Thematic analysis revealed six key themes: (1) Focusing on HIV prevention, (2) Establishing common entry-points for services, (3) Improving information availability, (4) Streamlining funding streams, (5) Removing competitiveness and (6) Building trust. We recommend that in addition to addressing operational issues regarding service delivery and patient care, initiatives to improve HIV service systems should address underlying social issues such as building trust.

Kaizen practice in healthcare: a qualitative analysis of hospital employees' suggestions for improvement

2016-01-01

Objectives Kaizen, or continuous improvement, lies at the core of lean. Kaizen is implemented through practices that enable employees to propose ideas for improvement and solve problems. The aim of this study is to describe the types of issues and improvement suggestions that hospital employees feel empowered to address through kaizen practices in order to understand when and how kaizen is used in healthcare. Methods We analysed 186 structured kaizen documents containing improvement suggestions that were produced by 165 employees at a Swedish hospital. Directed content analysis was used to categorise the suggestions into following categories: type of situation (proactive or reactive) triggering an action; type of process addressed (technical/administrative, support and clinical); complexity level (simple or complex); and type of outcomes aimed for (operational or sociotechnical). Compliance to the kaizen template was calculated. Results 72% of the improvement suggestions were reactions to a perceived problem. Support, technical and administrative, and primary clinical processes were involved in 47%, 38% and 16% of the suggestions, respectively. The majority of the kaizen documents addressed simple situations and focused on operational outcomes. The degree of compliance to the kaizen template was high for several items concerning the identification of problems and the proposed solutions, and low for items related to the test and implementation of solutions. Conclusions There is a need to combine kaizen practices with improvement and innovation practices that help staff and managers to address complex issues, such as the improvement of clinical care processes. The limited focus on sociotechnical aspects and the partial compliance to kaizen templates may indicate a limited understanding of the entire kaizen process and of how it relates to the overall organisational goals. This in turn can hamper the sustainability of kaizen practices and results. PMID:27473953

A total of seven ethical topics were identified: ethical approval (94% of the dissertations), information and informed consent (86%), confidentiality (67%), ethical aspects of methods (61%), use of ethical principles and regulations (39%), rationale for the study (20%) and fair participant selection (14%). Four of those of topics were most frequently addressed: the majority of dissertations (72%) included 3-5 issues. While many ethical concerns, by their nature, involve systematic concepts or metasystematic principles, ethical reasoning scored predominantly at lesser levels of complexity: abstract (6% of the dissertations), formal (84%) and systematic (10%). Research ethics are inadequately covered in most dissertations by nurses in Sweden. Important ethical concerns are missing, and the complexity of reasoning on ethical principles, motives and implications is insufficient. This is partly due to traditions and norms that discount ethical concerns but is probably also a reflection of the ability of PhD students and supervisors to handle complexity in general. It is suggested that the importance of ethical considerations should be emphasised in graduate and post-graduate studies and that individuals with capacity to deal with systematic and metasystematic concepts are recruited to senior research positions.

Fort Collins Science Center Ecosystem Dynamics branch--interdisciplinary research for addressing complex natural resource issues across landscapes and time

The Ecosystem Dynamics Branch of the Fort Collins Science Center offers an interdisciplinary team of talented and creative scientists with expertise in biology, botany, ecology, geology, biogeochemistry, physical sciences, geographic information systems, and remote-sensing, for tackling complex questions about natural resources. As demand for natural resources increases, the issues facing natural resource managers, planners, policy makers, industry, and private landowners are increasing in spatial and temporal scope, often involving entire regions, multiple jurisdictions, and long timeframes. Needs for addressing these issues include (1) a better understanding of biotic and abiotic ecosystem components and their complex interactions; (2) the ability to easily monitor, assess, and visualize the spatially complex movements of animals, plants, water, and elements across highly variable landscapes; and (3) the techniques for accurately predicting both immediate and long-term responses of system components to natural and human-caused change. The overall objectives of our research are to provide the knowledge, tools, and techniques needed by the U.S. Department of the Interior, state agencies, and other stakeholders in their endeavors to meet the demand for natural resources while conserving biodiversity and ecosystem services. Ecosystem Dynamics scientists use field and laboratory research, data assimilation, and ecological modeling to understand ecosystem patterns, trends, and mechanistic processes. This information is used to predict the outcomes of changes imposed on species, habitats, landscapes, and climate across spatiotemporal scales. The products we develop include conceptual models to illustrate system structure and processes; regional baseline and integrated assessments; predictive spatial and mathematical models; literature syntheses; and frameworks or protocols for improved ecosystem monitoring, adaptive management, and program evaluation. The descriptions in this fact sheet provide snapshots of our three research emphases, followed by descriptions of select current projects.

Narrative Inquiry for Science Education: Teachers' repertoire-making in the case of environmental curriculum

NASA Astrophysics Data System (ADS)

Hwang, Seyoung

2011-04-01

This paper considers how the school science curriculum can be conceptualised in order to address the contingent and complex nature of environmental and sustainability-related knowledge and understanding. A special concern lies in the development of research perspectives and tools for investigating ways, in which teachers are faced with complex and various situations in the sense-making of science-related issues, and subsequent pedagogic issues. Based on an empirical examination of Korean teachers' sense-making of their curricular practice, the paper develops a narrative approach to teachers' perspectives and knowledge by considering the value of stories as sense-making tools for reflective questioning of what is worth teaching, how and why. By employing the idea of 'repertoire', the study regards teachers' stories about their environment-related personal and teaching experiences as offering angles with which to understand teachers' motivation and reflection in curricular development and implementation. Furthermore, three empirical cases present ways in which the nature of knowledge and understanding is recognised and potentially integrated into pedagogies through teachers' narratives. Finally, the paper argues for the need to reconsider the role of the science teacher in addressing environmental and sustainability-related issues, in ways that facilitate teachers' reflexive interpretation of meanings in cultural texts and the construction of pedagogic text.

On March 13-15, 2007 nearly 50 scientists and administrators from the US and Canada participated in a Smithsonian-sponsored Wildlife Toxicology Workshop. Invitees were from academic, government, conservation and the private organizations and were selected to represent the diverse disciplines that encompass wildlife toxicology. The workshop addressed scientific and policy issues, strengths and weaknesses of current research strategies, interdisciplinary and science-based approaches in the study of complex contaminant issues, mechanisms for disseminating data to policy-makers, and the development of a partner network to meet the challenges facing wildlife toxicology over the next decade. Prior to the meeting, participants were asked to submit issues they deemed to be of highest concern which shaped four thematic groups for discussion: Wildlife Toxicology in Education, Risk Assessment, Multiple Stressors/Complex Mixtures, and Sub-Lethal to Population-Level Effects. From these discussion groups, 18 problem statements were developed and prioritized outlining what were deemed the most important issues to address now and into the future. Along with each problem statement participants developed potential solutions and action steps geared to move each issue forward. The workshop served as a stepping stone for action in the field of wildlife toxicology. These problem statements and the resulting action items are presented to the inter-disciplinary wildlife toxicology community for adoption, and future work and action items in these areas are encouraged. The workshop outcome looks to generate conversation and collaboration that will lead to the development of innovative research, future mechanisms for funding, workshops, working groups, and listserves within the wildlife toxicology community.

Studies are needed to inform the preparation of community nurses to address patient behavioral and social factors contributing to unnecessary readmissions to hospital. This study uses nurses' input to understand challenges faced during home care, to derive a framework to address the challenges. Semistructured interviews were conducted to saturation with 16 community nurses in Singapore. Interviews were transcribed verbatim and transcripts independently coded for emergent themes. Themes were interpreted using grounded theory. Seven major themes emerged from 16 interviews: Strained social relationships, complex care decision-making processes within families, communication barriers, patient's or caregiver neglect of health issues, building and maintaining trust, trial-and-error nature of work, and dealing with uncertainty. Community nurses identified uncertainty arising from complexities in social-relational, personal, and organizational factors as a central challenge. Nursing education should focus on navigating and managing uncertainty at the personal, patient, and family levels.

Single-stage-to-orbit versus two-stage-two-orbit: A cost perspective

NASA Astrophysics Data System (ADS)

Hamaker, Joseph W.

1996-03-01

This paper considers the possible life-cycle costs of single-stage-to-orbit (SSTO) and two-stage-to-orbit (TSTO) reusable launch vehicles (RLV's). The analysis parametrically addresses the issue such that the preferred economic choice comes down to the relative complexity of the TSTO compared to the SSTO. The analysis defines the boundary complexity conditions at which the two configurations have equal life-cycle costs, and finally, makes a case for the economic preference of SSTO over TSTO.

Need for Enhanced Environmental Representation in the Implementation of One Health.

PubMed

Barrett, Meredith A; Bouley, Timothy A

2015-06-01

Issues of global environmental change, global health, emerging disease, and sustainability present some of the most complex challenges of the twenty-first century. Individual disciplines cannot address these issues in isolation. Proactive, innovative, and trans-disciplinary solutions are required. Recognizing the inherent connectedness of humans, animals, plants, and their shared environment, One Health encourages the collaboration of many disciplines-including human and veterinary medicine, public health, social science, public policy, environmental science, and others-to address global and local health challenges. Despite great progress in this shift toward transdisciplinarity, the environmental component of the One Health paradigm remains underrepresented in One Health discourse. Human and animal health issues are commonly discussed under the umbrella of the One Health paradigm, while upstream environmental drivers and solutions are less prominent. We assessed the current integration of environmental issues in One Health publications and leadership. There is room for enhanced integration of environmental knowledge in the implementation of One Health approaches. We discuss the potential benefits from the collaboration between One Health and ecohealth, and explore strategies for increased environmental involvement.

Systematic and transparent inclusion of ethical issues and recommendations in clinical practice guidelines: a six-step approach.

PubMed

Mertz, Marcel; Strech, Daniel

2014-12-04

Clinical practice guidelines (CPGs), a core tool to foster medical professionalism, differ widely in whether and how they address disease-specific ethical issues (DSEIs), and current manuals for CPG development are silent on this issue. The implementation of an explicit method faces two core challenges: first, it adds further complexity to CPG development and requires human and financial resources. Second, in contrast to the in-depth treatment of ethical issues that is standard in bioethics, the inclusion of DSEIs in CPGs need to be more pragmatic, reductive, and simplistic, but without rendering the resulting recommendations useless or insufficiently justified. This paper outlines a six-step approach, EthicsGuide, for the systematic and transparent inclusion of ethical issues and recommendations in CPGs. The development of EthicsGuide is based on (a) methodological standards in evidence-based CPG development, (b) principles of bioethics, (c) research findings on how DSEIs are currently addressed in CPGs, and (d) findings from two proof-of-concept analyses of the EthicsGuide approach. The six steps are 1) determine the DSEI spectrum and the need for ethical recommendations; 2) develop statements on which to base ethical recommendations; 3) categorize, classify, condense, and paraphrase the statements; 4) write recommendations in a standard form; 5) validate and justify recommendations, making any necessary modifications; and 6) address consent. All six steps necessarily come into play when including DSEIs in CPGs. If DSEIs are not explicitly addressed, they are unavoidably dealt with implicitly. We believe that as ethicists gain greater involvement in decision-making about health, personal rights, or economic issues, they should make their methods transparent and replicable by other researchers; and as ethical issues become more widely reflected in CPGs, CPG developers have to learn how to address them in a methodologically adequate way. The approach proposed should serve as a basis for further discussion on how to reach these goals. It breaks open the black box of what ethicists implicitly do when they develop recommendations. Further, interdisciplinary discussion and pilot tests are needed to explore the minimal requirements that guarantee a simplified procedure which is still acceptable and does not become mere window dressing.

Objectives The perspectives, needs and preferences of individuals with complex health and social needs can be overlooked in the design of healthcare interventions. This study was designed to provide new insights on patient perspectives drawing from the qualitative evaluation of 5 complex healthcare interventions. Setting Patients and their caregivers were recruited from 5 interventions based in primary, hospital and community care in Ontario, Canada. Participants We included 62 interviews from 44 patients and 18 non-clinical caregivers. Intervention Our team analysed the transcripts from 5 distinct projects. This approach to qualitative meta-evaluation identifies common issues described by a diverse group of patients, therefore providing potential insights into systems issues. Outcome measures This study is a secondary analysis of qualitative data; therefore, no outcome measures were identified. Results We identified 5 broad themes that capture the patients’ experience and highlight issues that might not be adequately addressed in complex interventions. In our study, we found that: (1) the emergency department is the unavoidable point of care; (2) patients and caregivers are part of complex and variable family systems; (3) non-medical issues mediate patients’ experiences of health and healthcare delivery; (4) the unanticipated consequences of complex healthcare interventions are often the most valuable; and (5) patient experiences are shaped by the healthcare discourses on medically complex patients. Conclusions Our findings suggest that key assumptions about patients that inform intervention design need to be made explicit in order to build capacity to better understand and support patients with multiple chronic diseases. Across many health systems internationally, multiple models are being implemented simultaneously that may have shared features and target similar patients, and a qualitative meta-evaluation approach, thus offers an opportunity for cumulative learning at a system level in addition to informing intervention design and modification.

Cotter, G.; Frame, M.T.

2000-01-01

Looking out an office window or exploring a community park, one can easily see the tremendous challenges that biological information presents the computer science community. Biological information varies in format and content depending whether or not it is information pertaining to a particular species (i.e. Brown Tree Snake), or a specific ecosystem, which often includes multiple species, land use characteristics, and geospatially referenced information. The complexity and uniqueness of each individual species or ecosystem do not easily lend themselves to today's computer science tools and applications. To address the challenges that the biological enterprise presents the National Biological Information Infrastructure (NBII) (http://www.nbii.gov) was established in 1993. The NBII is designed to address these issues on a National scale within the United States, and through international partnerships abroad. This paper discusses current computer science efforts within the National Biological Information Infrastructure Program and future computer science research endeavors that are needed to address the ever-growing issues related to our Nation's biological concerns.

Each year, the developed world is flooded with complex new medical technologies, from robotic prosthetics to remote-controlled aspirin implants. Meanwhile, only about 10% of health research funds are spent addressing the pressing problems of developing nations, although these countries make up 93% of the worldwide burden of disease. In short, while a small fraction of the world pops brand-name pharmaceuticals, the majority suffers from poor sanitation, contaminated drinking water, preventable disease, and child mortality.

2010-11-01

As planning for sustainable municipal solid waste management has to address several inter-connected issues such as landfill capacity, environmental impacts and financial expenditure, it becomes increasingly necessary to understand the dynamic nature of their interactions. A system dynamics approach designed here attempts to address some of these issues by fitting a model framework for Newark urban region in the US, and running a forecast simulation. The dynamic system developed in this study incorporates the complexity of the waste generation and management process to some extent which is achieved through a combination of simpler sub-processes that are linked together to form a whole. The impact of decision options on the generation of waste in the city, on the remaining landfill capacity of the state, and on the economic cost or benefit actualized by different waste processing options are explored through this approach, providing valuable insights into the urban waste-management process.

2017-01-01

Aims To conduct a qualitative needs assessment of Directors of Nursing regarding challenges and recommendations for addressing sexual expression and consent. Background Sexual expression management among long-term care residents is a complex issue for nursing home staff. Little guidance is available for those wanting to follow a person-centred approach. Policies and procedures are needed, and must be usable across long-term care settings. Design Qualitative design for in-depth exploration. Methods Semi-structured interviews were conducted with 20 Directors of Nursing in the spring and summer of 2013, representing a range of regions, facility sizes and resident populations. Interview questions prompted them to identify recommendations that address challenges to improving sexual expression management in long-term care settings. Results Comparative thematic analysis resulted in several codes, which were grouped into eight overall categories. Recommendation categories that addressed key challenges included: address the issue, make environmental changes, identify staff expertise, provide education and training, assess sexuality initially and recurrently, establish policies/procedures for sexual expression management, develop assessment tools for sexual expression and consent, and clarify legal issues. The recommendation to develop national guidelines was observed across categories. Discussion Directors of Nursing report several challenges to sexual expression management in their facilities, and perceive their current methods to be ad hoc. A proactive approach to policy and procedure development is needed. PMID:27188413

Challenges in global ballast water management.

2004-04-01

Ballast water management is a complex issue raising the challenge of merging international regulations, ship's specific configurations along with ecological conservation. This complexity is illustrated in this paper by considering ballast water volume, discharge frequency, ship safety and operational issues aligned with regional characteristics to address ecological risk for selected routes. A re-estimation of ballast water volumes gives a global annual level of 3500 Mton. Global ballast water volume discharged into open sea originating from ballast water exchange operations is estimated to approximately 2800 Mton. Risk based decision support systems coupled to databases for different ports and invasive species characteristics and distributions can allow for differentiated treatment levels while maintaining low risk levels. On certain routes, the risk is estimated to be unacceptable and some kind of ballast water treatment or management should be applied.

Transitions between superstatistical regimes: Validity, breakdown and applications

NASA Astrophysics Data System (ADS)

Jizba, Petr; Korbel, Jan; Lavička, Hynek; Prokš, Martin; Svoboda, Václav; Beck, Christian

2018-03-01

Superstatistics is a widely employed tool of non-equilibrium statistical physics which plays an important rôle in analysis of hierarchical complex dynamical systems. Yet, its "canonical" formulation in terms of a single nuisance parameter is often too restrictive when applied to complex empirical data. Here we show that a multi-scale generalization of the superstatistics paradigm is more versatile, allowing to address such pertinent issues as transmutation of statistics or inter-scale stochastic behavior. To put some flesh on the bare bones, we provide a numerical evidence for a transition between two superstatistics regimes, by analyzing high-frequency (minute-tick) data for share-price returns of seven selected companies. Salient issues, such as breakdown of superstatistics in fractional diffusion processes or connection with Brownian subordination are also briefly discussed.

Overview of Contemporary Issues of Forest Research and Management in China

He, Hong S.; Shifley, Stephen R.; Thompson, Frank R.

2011-12-01

With 207 million ha of forest covering 22% of its land area, China ranks fifth in the world in forest area. Rapid economic growth, climate change, and forest disturbances pose new, complex challenges for forest research and management. Progress in meeting these challenges is relevant beyond China, because China's forests represent 34% of Asia's forests and 5% of the worlds' forests. To provide a broader understanding of these management challenges and of research and policies that address them, we organized this special issue on contemporary forest research and management issues in China. At the national level, papers review major forest types and the evolution of sustainable forestry, the development of China's forest-certification efforts, the establishment of a forest inventory system, and achievements and challenges in insect pest control in China. Papers focused on Northern China address historical, social, and political factors that have shaped the region's forests; the use of forest landscape models to assess how forest management can achieve multiple objectives; and analysis and modeling of fuels and fire behavior. Papers addressing Central and South China describe the "Grain for Green" program, which converts low productivity cropland to grassland and woodland to address erosion and soil carbon sequestration; the potential effects of climate change on CO2 efflux and soil respiration; and relationships between climate and net primary productivity. China shares many forest management and research issues with other countries, but in other cases China's capacity to respond to forest management challenges is unique and bears watching by the rest of the world.

Deutsch, Jared L., E-mail: jdeutsch@ualberta.ca; Palmer, Kevin; Deutsch, Clayton V.

High-resolution spatial numerical models of metallurgical properties constrained by geological controls and more extensively by measured grade and geomechanical properties constitute an important part of geometallurgy. Geostatistical and other numerical techniques are adapted and developed to construct these high-resolution models accounting for all available data. Important issues that must be addressed include unequal sampling of the metallurgical properties versus grade assays, measurements at different scale, and complex nonlinear averaging of many metallurgical parameters. This paper establishes techniques to address each of these issues with the required implementation details and also demonstrates geometallurgical mineral deposit characterization for a copper–molybdenum deposit inmore » South America. High-resolution models of grades and comminution indices are constructed, checked, and are rigorously validated. The workflow demonstrated in this case study is applicable to many other deposit types.« less

Addressing Dynamic Issues of Program Model Checking

NASA Technical Reports Server (NTRS)

Lerda, Flavio; Visser, Willem

2001-01-01

Model checking real programs has recently become an active research area. Programs however exhibit two characteristics that make model checking difficult: the complexity of their state and the dynamic nature of many programs. Here we address both these issues within the context of the Java PathFinder (JPF) model checker. Firstly, we will show how the state of a Java program can be encoded efficiently and how this encoding can be exploited to improve model checking. Next we show how to use symmetry reductions to alleviate some of the problems introduced by the dynamic nature of Java programs. Lastly, we show how distributed model checking of a dynamic program can be achieved, and furthermore, how dynamic partitions of the state space can improve model checking. We support all our findings with results from applying these techniques within the JPF model checker.

A review of agent-based modeling approach in the supply chain collaboration context

NASA Astrophysics Data System (ADS)

Arvitrida, N. I.

2018-04-01

Collaboration is considered as the key aspect of supply chain management (SCM) success. This issue has been addressed by many studies in recent years, but there are still few research employs agent-based modeling (ABM) approach to study business partnerships in SCM. This paper reviews the use of ABM in modeling collaboration in supply chains and inform the scope of ABM application in the existing literature. The review reveals that ABM can be an effective tool to address various aspects in supply chain relationships, but its applications in SCM studies are still limited. Moreover, where ABM is applied in the SCM context, most of the studies focus on software architecture rather than analyzing the supply chain issues. This paper also provides insights to SCM researchers about the opportunity uses of ABM in studying complexity in supply chain collaboration.

Global perspectives on nursing and its contribution to healthcare and health policy: thoughts on an emerging policy model.

PubMed

Shamian, Judith

2014-12-01

We know from rigorous evidence that nurses can exert an incredible impact on the everyday lives of people and their health. Nurses can also contribute in much wider spheres of influence by applying their knowledge and skills to address broader issues affecting population health across communities, nations and globally. Despite the prevalence of so many vexing health and social issues, nurses often fail to think globally, or even regionally, when they are lobbying for change. And while much political influence is local, some issues are simply too complex to rely on local influence alone. Importantly in all this, we must acknowledge the ways these complex health issues are shaped by economic and political agendas and not necessarily by healthcare agendas. As such, the nursing community has to act globally and locally, both within and outside of the nursing arena. This paper explores early thinking about an evolving model of spheres--or "bubbles"--of policy influence in which nurses can and must operate to more effectively impact key global health and healthcare challenges.

Kaizen, or continuous improvement, lies at the core of lean. Kaizen is implemented through practices that enable employees to propose ideas for improvement and solve problems. The aim of this study is to describe the types of issues and improvement suggestions that hospital employees feel empowered to address through kaizen practices in order to understand when and how kaizen is used in healthcare. We analysed 186 structured kaizen documents containing improvement suggestions that were produced by 165 employees at a Swedish hospital. Directed content analysis was used to categorise the suggestions into following categories: type of situation (proactive or reactive) triggering an action; type of process addressed (technical/administrative, support and clinical); complexity level (simple or complex); and type of outcomes aimed for (operational or sociotechnical). Compliance to the kaizen template was calculated. 72% of the improvement suggestions were reactions to a perceived problem. Support, technical and administrative, and primary clinical processes were involved in 47%, 38% and 16% of the suggestions, respectively. The majority of the kaizen documents addressed simple situations and focused on operational outcomes. The degree of compliance to the kaizen template was high for several items concerning the identification of problems and the proposed solutions, and low for items related to the test and implementation of solutions. There is a need to combine kaizen practices with improvement and innovation practices that help staff and managers to address complex issues, such as the improvement of clinical care processes. The limited focus on sociotechnical aspects and the partial compliance to kaizen templates may indicate a limited understanding of the entire kaizen process and of how it relates to the overall organisational goals. This in turn can hamper the sustainability of kaizen practices and results. Published by the BMJ Publishing Group Limited.

Augmenting team cognition in human-automation teams performing in complex operational environments.

Cuevas, Haydee M; Fiore, Stephen M; Caldwell, Barrett S; Strater, Laura

2007-05-01

There is a growing reliance on automation (e.g., intelligent agents, semi-autonomous robotic systems) to effectively execute increasingly cognitively complex tasks. Successful team performance for such tasks has become even more dependent on team cognition, addressing both human-human and human-automation teams. Team cognition can be viewed as the binding mechanism that produces coordinated behavior within experienced teams, emerging from the interplay between each team member's individual cognition and team process behaviors (e.g., coordination, communication). In order to better understand team cognition in human-automation teams, team performance models need to address issues surrounding the effect of human-agent and human-robot interaction on critical team processes such as coordination and communication. Toward this end, we present a preliminary theoretical framework illustrating how the design and implementation of automation technology may influence team cognition and team coordination in complex operational environments. Integrating constructs from organizational and cognitive science, our proposed framework outlines how information exchange and updating between humans and automation technology may affect lower-level (e.g., working memory) and higher-level (e.g., sense making) cognitive processes as well as teams' higher-order "metacognitive" processes (e.g., performance monitoring). Issues surrounding human-automation interaction are discussed and implications are presented within the context of designing automation technology to improve task performance in human-automation teams.

2005-01-01

Space exploration applications offer a unique opportunity for the development and deployment of autonomous systems, due to limited communications, large distances, and great expense of direct operation. At the same time, the risk and cost of space missions leads to reluctance to taking on new, complex and difficult-to-understand technology. A key issue in addressing these concerns is the validation of autonomous systems. In recent years, higher-level autonomous systems have been applied in space applications. In this presentation, we will highlight those autonomous systems, and discuss issues in validating these systems. We will then look to future demands on validating autonomous systems for space, identify promising technologies and open issues.

People with serious mental illness (service users) have needs related to sexual health and sexuality, yet these have been poorly addressed in mental health services. In the present study, we report the current practice of mental health professionals in relation to sexual health. Focus groups conducted in two mental health trusts explored routine practice in relation to discussing, assessing, and planning care in relation to sexual health. A thematic analysis identified seven themes: (i) sexual health provision is a complex issue; (ii) mental health staff are aware of sexual health needs; (iii) current provision regarding sexual health is 'neglected'; (iv) barriers to sexual health provision; (v) enabling a discussion around sexual health; (vi) sexual health provision is a role for mental health professionals; and (vii) training needs. Mental health staff are aware of complex issues related to sexual health for service users, but this is mainly seen through the lens of risk management and safeguarding. We need to develop the mental health workforce to be able to incorporate sexual health into routine health care. © 2017 Australian College of Mental Health Nurses Inc.

Spacecraft Antennas

Jamnejad, Vahraz; Manshadi, Farzin; Rahmat-Samii, Yahya; Cramer, Paul

1990-01-01

Some of the various categories of issues that must be considered in the selection and design of spacecraft antennas for a Personal Access Satellite System (PASS) are addressed, and parametric studies for some of the antenna concepts to help the system designer in making the most appropriate antenna choice with regards to weight, size, and complexity, etc. are provided. The question of appropriate polarization for the spacecraft as well as for the User Terminal Antenna required particular attention and was studied in some depth. Circular polarization seems to be the favored outcome of this study. Another problem that has generally been a complicating factor in designing the multiple beam reflector antennas, is the type of feeds (single vs. multiple element and overlapping vs. non-overlapping clusters) needed for generating the beams. This choice is dependent on certain system design factors, such as the required frequency reuse, acceptable interbeam isolation, antenna efficiency, number of beams scanned, and beam-forming network (BFN) complexity. This issue is partially addressed, but is not completely resolved. Indications are that it may be possible to use relatively simple non-overlapping clusters of only a few elements, unless a large frequency reuse and very stringent isolation levels are required.

Among other important issues to consider in the control of such systems, the location and number of actuators and sensors are essential to effectively control and suppress vibration. We first address the selection of proper actuator and sensor locations leading to a controllable and observable system. The Rayleigh-Ritz modal analysis method is used to develop a lumped-parameter model of a flexible vibration isolation table top. This model is then used to investigate the system's controllability and observability including the coupling effects introduced by the magnetic bearing. This analysis results in necessary and sufficient conditions for proper selection of actuator and sensor locations. These locations are also important for both controller system's complexity and stability of point of views. A favorable pole-zero plot of the open loop transfer functions is presented. Necessary and sufficient conditions for reducing the controller complexity are derived. The results are illustrated by examples using approximate mode shape functions.

Cybersecurity vulnerabilities in medical devices: a complex environment and multifaceted problem

PubMed Central

Williams, Patricia AH; Woodward, Andrew J

2015-01-01

The increased connectivity to existing computer networks has exposed medical devices to cybersecurity vulnerabilities from which they were previously shielded. For the prevention of cybersecurity incidents, it is important to recognize the complexity of the operational environment as well as to catalog the technical vulnerabilities. Cybersecurity protection is not just a technical issue; it is a richer and more intricate problem to solve. A review of the factors that contribute to such a potentially insecure environment, together with the identification of the vulnerabilities, is important for understanding why these vulnerabilities persist and what the solution space should look like. This multifaceted problem must be viewed from a systemic perspective if adequate protection is to be put in place and patient safety concerns addressed. This requires technical controls, governance, resilience measures, consolidated reporting, context expertise, regulation, and standards. It is evident that a coordinated, proactive approach to address this complex challenge is essential. In the interim, patient safety is under threat. PMID:26229513

A category adjustment approach to memory for spatial location in natural scenes.

PubMed

Holden, Mark P; Curby, Kim M; Newcombe, Nora S; Shipley, Thomas F

2010-05-01

Memories for spatial locations often show systematic errors toward the central value of the surrounding region. This bias has been explained using a Bayesian model in which fine-grained and categorical information are combined (Huttenlocher, Hedges, & Duncan, 1991). However, experiments testing this model have largely used locations contained in simple geometric shapes. Use of this paradigm raises 2 issues. First, do results generalize to the complex natural world? Second, what types of information might be used to segment complex spaces into constituent categories? Experiment 1 addressed the 1st question by showing a bias toward prototypical values in memory for spatial locations in complex natural scenes. Experiment 2 addressed the 2nd question by manipulating the availability of basic visual cues (using color negatives) or of semantic information about the scene (using inverted images). Error patterns suggest that both perceptual and conceptual information are involved in segmentation. The possible neurological foundations of location memory of this kind are discussed.

Has anyone seen it? Health care in Croatian elections.

PubMed

Radin, Dagmar; Džakula, Aleksandar

2012-01-01

Over the past decade, public opinion surveys have shown that Croats are deeply dissatisfied with their health care system and asses it to be one of the most important issues. However, health care hardly makes it into any political discourse in Croatia. This study analyzes the results of a public opinion survey conducted before the 2007 parliamentary elections to find out what the public sentiment on health care performance in Croatia is and to analyze the reasons why health care is not addressed by political actors. Evidence suggests that while health care is the most salient issue today, the public often understands it poorly. Thus, in a political environment of competing issues, and given the complexity of tacking health care in the policy arena, politicians strategically avoid discussing the issue.

Negotiating the Relationship Between Addiction, Ethics, and Brain Science

PubMed Central

Buchman, Daniel Z.; Skinner, Wayne; Illes, Judy

2010-01-01

Advances in neuroscience are changing how mental health issues such as addiction are understood and addressed as a brain disease. Although a brain disease model legitimizes addiction as a medical condition, it promotes neuro-essentialist thinking, categorical ideas of responsibility and free choice, and undermines the complexity involved in its emergence. We propose a ‘biopsychosocial systems’ model where psycho-social factors complement and interact with neurogenetics. A systems approach addresses the complexity of addiction and approaches free choice and moral responsibility within the biological, lived experience and socio-historical context of the individual. We examine heroin-assisted treatment as an applied case example within our framework. We conclude with a discussion of the model and its implications for drug policy, research, addiction health care systems and delivery, and treatment of substance use problems. PMID:20676352

Hardware-in-the-loop environment facility to address pilot-vehicle-interface issues of a fighter aircraft

NASA Astrophysics Data System (ADS)

Pandurangareddy, Meenige

2002-07-01

The evolution of Pilot-Vehicle-Interface (PVI) of a fighter aircraft is a complex task. The PVI design involves both static and dynamic issues. Static issues involve the study of reach of controls and switches, ejection path clearance, readability of indicators and display symbols, etc. Dynamic issues involve the study of the effect of aircraft motion on display symbols, pilot emergency handling, situation awareness, weapon aiming, etc. This paper describes a method of addressing the above issues by building a facility with cockpit, which is ergonomically similar to the fighter cockpit. The cockpit is also fitted with actual displays, controls and switches. The cockpit is interfaced with various simulation models of aircraft and outside-window-image generators. The architecture of the facility is designed to represent the latencies of the aircraft and facilitates replacement of simulation models with actual units. A parameter injection facility could be used to induce faults in a comprehensive manner. Pilots could use the facility right from familiarising themselves with procedures to start the engine, take-off, navigate, aim the weapons, handling of emergencies and landing. This approach is being followed and further being enhanced on Cockpit-Environment-Facility (CEF) at Aeronautical Development Agency (ADA), Bangalore, India.

Research gaps in understanding flood changes at the catchment scale caused by changes in forest management, agricultural practices, artificial drainage, and terracing are identified. Potential strategies in addressing these gaps are proposed, such as complex systems approaches to link processes across time scales, long-term experiments on physical-chemical-biological process interactions, and a focus on connectivity and patterns across spatial scales. It is suggested that these strategies will stimulate new research that coherently addresses the issues across hydrology, soil and agricultural sciences, forest engineering, forest ecology, and geomorphology.

There is increasing evidence that the Internet and social media can influence suicide-related behavior. Important questions are whether this influence poses a significant risk to the public and how public health approaches might be used to address the issue. To address these questions, we provide an overview of ways that social media can influence suicidal behavior, both negatively and positively, and we evaluate the evidence of the risk. We also discuss the legal complexities of this important topic and propose future directions for research and prevention programs based on a public health perspective. PMID:22401525

This paper will address the issue of human factor aspects of civil flight deck certification, with emphasis on the pilot's interface with automation. In particular, three questions will be asked that relate to this certification process: (1) are the methods, data, and guidelines available from human factors to adequately address the problems of certifying as safe and error tolerant the complex automated systems of modern civil transport aircraft; (2) do aircraft manufacturers effectively apply human factors information during the aircraft flight deck design process; and (3) do regulatory authorities effectively apply human factors information during the aircraft certification process?

Regulating the chromatin landscape: structural and mechanistic perspectives.

PubMed

Bartholomew, Blaine

2014-01-01

A large family of chromatin remodelers that noncovalently modify chromatin is crucial in cell development and differentiation. They are often the targets of cancer, neurological disorders, and other human diseases. These complexes alter nucleosome positioning, higher-order chromatin structure, and nuclear organization. They also assemble chromatin, exchange out histone variants, and disassemble chromatin at defined locations. We review aspects of the structural organization of these complexes, the functional properties of their protein domains, and variation between complexes. We also address the mechanistic details of these complexes in mobilizing nucleosomes and altering chromatin structure. A better understanding of these issues will be vital for further analyses of subunits of these chromatin remodelers, which are being identified as targets in human diseases by NGS (next-generation sequencing).

Having gained momentum in the last decade, the One Health initiative promotes a holistic approach to address complex global health issues. Before recommending its adoption to stakeholders, however, it is paramount to first compile quantitative evidence of the benefit of such an approach. The aim of this scoping review was to identify and summarize primary research that describes monetary and non-monetary outcomes following adoption of a One Health approach. An extensive literature search yielded a total of 42,167 references, of which 85 were included in the final analysis. The top two biotic health issues addressed in these studies were rabies and malaria; the top abiotic health issue was air pollution. Most studies described collaborations between human and animal (n = 42), or human and environmental disciplines (n = 41); commonly reported interventions included vector control and animal vaccination. Monetary outcomes were commonly expressed as cost-benefit or cost-utility ratios; non-monetary outcomes were described using disease frequency or disease burden measurements. The majority of the studies reported positive or partially positive outcomes. This paper illustrates the variety of health challenges that can be addressed using a One Health approach, and provides tangible quantitative measures that can be used to evaluate future implementations of the One Health approach.

Tool for evaluating research implementation challenges: A sense-making protocol for addressing implementation challenges in complex research settings

PubMed Central

2013-01-01

Background Many challenges arise in complex organizational interventions that threaten research integrity. This article describes a Tool for Evaluating Research Implementation Challenges (TECH), developed using a complexity science framework to assist research teams in assessing and managing these challenges. Methods During the implementation of a multi-site, randomized controlled trial (RCT) of organizational interventions to reduce resident falls in eight nursing homes, we inductively developed, and later codified the TECH. The TECH was developed through processes that emerged from interactions among research team members and nursing home staff participants, including a purposive use of complexity science principles. Results The TECH provided a structure to assess challenges systematically, consider their potential impact on intervention feasibility and fidelity, and determine actions to take. We codified the process into an algorithm that can be adopted or adapted for other research projects. We present selected examples of the use of the TECH that are relevant to many complex interventions. Conclusions Complexity theory provides a useful lens through which research procedures can be developed to address implementation challenges that emerge from complex organizations and research designs. Sense-making is a group process in which diverse members interpret challenges when available information is ambiguous; the groups’ interpretations provide cues for taking action. Sense-making facilitates the creation of safe environments for generating innovative solutions that balance research integrity and practical issues. The challenges encountered during implementation of complex interventions are often unpredictable; however, adoption of a systematic process will allow investigators to address them in a consistent yet flexible manner, protecting fidelity. Research integrity is also protected by allowing for appropriate adaptations to intervention protocols that preserve the feasibility of ‘real world’ interventions. PMID:23281623

A framework for the comparative study of language.

PubMed

Uriagereka, Juan; Reggia, James A; Wilkinson, Gerald S

2013-07-18

Comparative studies of language are difficult because few language precursors are recognized. In this paper we propose a framework for designing experiments that test for structural and semantic patterns indicative of simple or complex grammars as originally described by Chomsky. We argue that a key issue is whether animals can recognize full recursion, which is the hallmark of context-free grammar. We discuss limitations of recent experiments that have attempted to address this issue, and point out that experiments aimed at detecting patterns that follow a Fibonacci series have advantages over other artificial context-free grammars. We also argue that experiments using complex sequences of behaviors could, in principle, provide evidence for fully recursive thought. Some of these ideas could also be approached using artificial life simulations, which have the potential to reveal the types of evolutionary transitions that could occur over time. Because the framework we propose has specific memory and computational requirements, future experiments could target candidate genes with the goal of revealing the genetic underpinnings of complex cognition.

Ethical issues in HIV prevention research with people who inject drugs.

PubMed

Sugarman, Jeremy; Rose, Scott M; Metzger, David

2014-04-01

Injection drug use continues to significantly contribute to new infections with HIV. Moreover, conducting HIV prevention research with people who inject drugs (PWIDs) can be complicated for an array of practical, social, legal, and ethical reasons. It is critical that these research efforts are sensitive to the particular vulnerabilities associated with injection drug use as well as those related to being at risk of acquiring HIV so as to minimize harm to participants in research. To describe how we addressed some of these ethical challenges during the course of a large-scale multinational randomized HIV prevention trial involving PWIDs, which was successfully completed. The ethical issues encountered during the life cycle of the trial were cataloged by the principal investigator, study coordinator, and ethicist working on the trial. Relevant study documents were then reviewed to provide pertinent details. The ethical issues unique to the trial were then described. Before implementation, the trial faced particularly complex challenges related to the vulnerability of PWIDs, where HIV seroincidence rates in the population were high and legal policies and stigma regarding injection drug use was severe. Accordingly, a rapid policy assessment was commissioned, and a series of community engagement activities were conducted. During the trial, in addition to using careful standard operating procedures regarding all aspects of trial conduct and extensive staff training, the trial standardized informed consent procedures and assessed them. Furthermore, social harms were monitored along with physical harms and adverse events. Following the decision to close the study, it was critical to develop an orderly and safe process for closing it. The issue of post-trial access to the study medication and a complex intervention also surfaced for consideration. The issues described in this article are necessarily limited to how they manifested themselves within the context of a particular trial that was conducted in two countries. In addition, other stakeholders may have divergent views on the ethical issues described and may also have identified additional ethical issues that would warrant examination. Adopting similar approaches to addressing ethical issues in future research promises to facilitate this work so that needed strategies to prevent HIV infection among PWIDs can be safely and appropriately tested. Future trials enrolling PWIDs who are at risk of detainment should identify ways of mapping closely their experiences and perceptions in order to better apprehend some of the ethical issues at stake. In addition, scholarly and policy work needs to address the ethical issues related to post-trial access to multi-modal interventions that may be desired by participants, but are not shown to be effective in achieving the primary outcomes of the study.

Understanding safety and production risks in rail engineering planning and protection.

PubMed

Wilson, John R; Ryan, Brendan; Schock, Alex; Ferreira, Pedro; Smith, Stuart; Pitsopoulos, Julia

2009-07-01

Much of the published human factors work on risk is to do with safety and within this is concerned with prediction and analysis of human error and with human reliability assessment. Less has been published on human factors contributions to understanding and managing project, business, engineering and other forms of risk and still less jointly assessing risk to do with broad issues of 'safety' and broad issues of 'production' or 'performance'. This paper contains a general commentary on human factors and assessment of risk of various kinds, in the context of the aims of ergonomics and concerns about being too risk averse. The paper then describes a specific project, in rail engineering, where the notion of a human factors case has been employed to analyse engineering functions and related human factors issues. A human factors issues register for potential system disturbances has been developed, prior to a human factors risk assessment, which jointly covers safety and production (engineering delivery) concerns. The paper concludes with a commentary on the potential relevance of a resilience engineering perspective to understanding rail engineering systems risk. Design, planning and management of complex systems will increasingly have to address the issue of making trade-offs between safety and production, and ergonomics should be central to this. The paper addresses the relevant issues and does so in an under-published domain - rail systems engineering work.

Aim This paper is a report of a study of the type, frequency, and level of stress of ethical issues encountered by nurses in their everyday practice. Background Everyday ethical issues in nursing practice attract little attention but can create stress for nurses. Nurses often feel uncomfortable in addressing the ethical issues they encounter in patient care. Methods A self-administered survey was sent in 2004 to 1000 nurses in four states in four different census regions of the United States of America. The adjusted response rate was 52%. Data were analyzed using descriptive statistics, cross-tabulations and Pearson correlations. Results A total of 422 questionnaires were used in the analysis. The five most frequently-occurring and most stressful ethical and patient care issues were protecting patients' rights; autonomy and informed consent to treatment; staffing patterns; advanced care planning; and surrogate decision-making. Other common occurrences were unethical practices of healthcare professionals; breaches of patient confidentiality or right to privacy; and end-of-life decision-making. Younger nurses and those with fewer years of experience encountered ethical issues more frequently and reported higher levels of stress. Nurses from different regions also experienced specific types of ethical problems more commonly. Conclusion Nurses face daily ethical challenges in the provision of quality care. To retain nurses, targeted ethics-related interventions that address caring for an increasingly complex patient population are needed. PMID:20735502

Medical photographic image capture and data management has undergone a rapid and compelling change in complexity over the last 20 years. This is because of multiple factors, including significant advances in ease of photograph capture, alongside an evolution of mechanisms of data portability/dissemination, combined with governmental focus on health information privacy. Literature to guide medical, legal, governmental and business professionals when dealing with issues related to medical photography is virtually nonexistent. Herein, we will address the breadth of uses of medical photography, device properties/specific devices utilised for image capture, methods of data transfer and dissemination and patient perceptions and attitudes regarding photography in a medical setting. In addition, we will address the legal implications, including legal precedent, copyright and privacy law, informed consent, protected health information and the Health Insurance Portability and Accountability Act (HIPAA), as they pertain to medical photography. © 2015 John Wiley & Sons Ltd.

Children with medical complexity in Canada

Dewan, Tammie; Cohen, Eyal

2013-01-01

The burden of chronic disease is placing pressure on the Canadian health care system. A small but important chronic disease population is children with medical complexity, defined as individuals with: high family-identified needs; complex chronic disease necessitating specialized care; functional disability; and high health care utilization. These patients present a challenge to community providers who are expected to provide holistic care and manage complex issues, often with a paucity of services and supports. Alternative models of care may address the complex needs of this population. In addition, strategies can be implemented in community practices that may assist with the care of children with medical complexity such as collaborative care, engagement of key workers, focus on goal-directed care and use of care plans. The paediatric community should engage in health care reform discussions focused on chronic disease to ensure that the complex needs of these children are met. PMID:24497777

Test item linguistic complexity and assessments for deaf students.

Cawthon, Stephanie

2011-01-01

Linguistic complexity of test items is one test format element that has been studied in the context of struggling readers and their participation in paper-and-pencil tests. The present article presents findings from an exploratory study on the potential relationship between linguistic complexity and test performance for deaf readers. A total of 64 students completed 52 multiple-choice items, 32 in mathematics and 20 in reading. These items were coded for linguistic complexity components of vocabulary, syntax, and discourse. Mathematics items had higher linguistic complexity ratings than reading items, but there were no significant relationships between item linguistic complexity scores and student performance on the test items. The discussion addresses issues related to the subject area, student proficiency levels in the test content, factors to look for in determining a "linguistic complexity effect," and areas for further research in test item development and deaf students.

The next generation of computer systems are studied by examining the processes and methodologies. The present generation is ok for small projects, but not so good for large projects. They are not good for addressing the iterative nature of requirements, resolution, and implementation. They do not address complexity issues of requirements stabilization. They do not explicitly address reuse opportunities, and they do not help with people shortages. Therefore, there is a need to define and automate improved software engineering processes. Some help may be gained by reuse and prototyping, which are two sides of the same coin. Reuse library parts are used to generate good approximations to desired solutions, i.e., prototypes. And rapid prototype composition implies use of preexistent parts, i.e., reusable parts.

Objective The diagnosis and treatment of gynecologic cancer can cause short- and long-term negative effects on sexual health and quality of life (QoL). The aim of this article is to present a comprehensive overview of the sexual health concerns of gynecologic cancer survivors and discuss evidence-based treatment options for commonly encountered sexual health issues. Methods A comprehensive literature search of English language studies on sexual health in gynecologic cancer survivors and the treatment of sexual dysfunction was conducted in MEDLINE databases. Relevant data are presented in this review. Additionally, personal and institutional practices are incorporated where relevant. Results Sexual dysfunction is prevalent among gynecologic cancer survivors as a result of surgery, radiation, and chemotherapy--negatively impacting QoL. Many patients expect their healthcare providers to address sexual health concerns, but most have never discussed sex-related issues with their physician. Lubricants, moisturizers, and dilators are effective, simple, non-hormonal interventions that can alleviate the morbidity of vaginal atrophy, stenosis, and pain. Pelvic floor physical therapy can be an additional tool to address dyspareunia. Cognitive behavioral therapy has been shown to be beneficial to patients reporting problems with sexual interest, arousal, and orgasm. Conclusion Oncology providers can make a significant impact on the QoL of gynecologic cancer survivors by addressing sexual health concerns. Simple strategies can be implemented into clinical practice to discuss and treat many sexual issues. Referral to specialized sexual health providers may be needed to address more complex problems.

A recent study by McHugh and Behar (2009) provided new findings relevant to these issues. McHugh and Behar calculated indices of readability separately for the instructions and the item sets of 105 self-report measures of anxiety and depression. Results revealed substantial variability in readability among the measures, with most measures being written at or above the mean reading grade level in the United States. These results were consistent with those reported previously by Schinka and Borum (1993, 1994) in analyses of the readability of commonly used self-report psychopathology and personality inventories. In their discussion, McHugh and Behar addressed implications of their findings for clinical assessment and for scale development. I expand on their comments by addressing the failure to consider vocabulary difficulty, a major shortcoming of readability indices that examine only text complexity. I demonstrate how vocabulary difficulty influences readability and discuss additional considerations and possible solutions for addressing the gap between scale readability and the reading skill level of the self-report respondent. The work of McHugh and Behar clearly demonstrates that the issues of reading ability that arise in collecting self-report data are neither simple nor straightforward. Comments are offered to focus attention on the problems identified by their work. These problems will require additional effort on the part of researchers and clinicians in order to obtain reliable, valid estimates of clinical status.

Recent manmade and natural disasters highlight weaknesses in the public health systems designed to protect populations from harm and minimize disruption of the social and built environments. Emergency planning and response efforts have, as a result, focused largely on ensuring populations' physical well-being during and after a disaster. Many public health authorities, including the World Health Organization, have recognized the importance of addressing both mental and physical health concerns in emergency plans. Individuals with mental disorders represent a notable proportion of the overall population, and anticipating their needs is critical to comprehensive emergency planning and response efforts. Because people with serious mental disorders historically have been stigmatized, and many individuals with mental disorders may be unable to care for themselves, ethical guidance may be of assistance to those engaged in emergency planning and response. This article considers several broad categories of ethical issues that arise during emergencies for people with serious mental disorders and offers recommendations for ways in which emergency planners and other stakeholders can begin to address these ethical challenges.

Understanding Nutritional Epidemiology and Its Role in Policy12

Satija, Ambika; Yu, Edward; Willett, Walter C; Hu, Frank B

2015-01-01

Nutritional epidemiology has recently been criticized on several fronts, including the inability to measure diet accurately, and for its reliance on observational studies to address etiologic questions. In addition, several recent meta-analyses with serious methodologic flaws have arrived at erroneous or misleading conclusions, reigniting controversy over formerly settled debates. All of this has raised questions regarding the ability of nutritional epidemiologic studies to inform policy. These criticisms, to a large degree, stem from a misunderstanding of the methodologic issues of the field and the inappropriate use of the drug trial paradigm in nutrition research. The exposure of interest in nutritional epidemiology is human diet, which is a complex system of interacting components that cumulatively affect health. Consequently, nutritional epidemiology constantly faces a unique set of challenges and continually develops specific methodologies to address these. Misunderstanding these issues can lead to the nonconstructive and sometimes naive criticisms we see today. This article aims to clarify common misunderstandings of nutritional epidemiology, address challenges to the field, and discuss the utility of nutritional science in guiding policy by focusing on 5 broad questions commonly asked of the field.

Innovative Use of the Law to Address Complex Global Health Problems Comment on "The Legal Strength of International Health Instruments - What It Brings toGlobal Health Governance?"

Walls, Helen L; Ooms, Gorik

2017-05-20

Addressing the increasingly globalised determinants of many important problems affecting human health is a complex task requiring collective action. We suggest that part of the solution to addressing intractable global health issues indeed lies with the role of new legal instruments in the form of globally binding treaties, as described in the recent article of Nikogosian and Kickbusch. However, in addition to the use of international law to develop new treaties, another part of the solution may lie in innovative use of existing legal instruments. A 2015 court ruling in The Hague, which ordered the Dutch government to cut greenhouse gas emissions by at least 25% within five years, complements this perspective, suggesting a way forward for addressing global health problems that critically involves civil society and innovative use of existing domestic legal instruments. © 2017 The Author(s); Published by Kerman University of Medical Sciences.

Cross-disciplinary research is necessary to solve many complex problems that affect society today, including problems involving linked social and environmental systems. Examples include natural resource management or scarcity problems, problematic effects of climate change, and environmental pollution issues. Intercultural research teams are needed to address many complex environmental matters as they often cross geographic and political boundaries, and involve people of different countries and cultures. It follows that disciplinarily and culturally diverse research teams have been organized to investigate and address environmental issues. This case study investigates a team composed of both monolingual and bilingual Chilean and US university researchers who are geoscientists, engineers and economists. The objective of this research team was to study both the natural and human parts of a hydrologic system in a hyper-arid region in northern Chile. Interviews (n = 8) addressed research questions focusing on the interaction of cross-disciplinary diversity and cultural diversity during group integration and development within the team. The case study revealed that the group struggled more with cross-disciplinary challenges than with intercultural ones. Particularly challenging ones were instances the of disciplinary crosstalk, or hidden misunderstandings, where team members thought they understood their cross-disciplinary colleagues, when in reality they did not. Results showed that translation served as a facilitator to cross-disciplinary integration of the research team. The use of translation in group meetings as a strategy for effective cross-disciplinary integration can be extended to monolingual cross-disciplinary teams as well.

The Medical School Admissions Process and Meeting the Public's Health Care Needs: Never the Twain Shall Meet?

Cleland, Jennifer

2017-12-19

Medical schools typically assess how good their selection process is using metrics such as students' assessment performance and the academic success of alumni on later indicators of academic ability and clinical competence, such as Royal College of Physicians or specialty board examinations. To address global issues with the maldistribution of doctors and increasing numbers of new medical school graduates choosing not to work in a clinical context requires different measurements of medical school admissions processes, like those related to graduates' career outcomes (e.g., working in underserved regions and/or working in certain specialties). This shift in focus is not straightforward. Medical education is a complex social system where, intentionally or not, medical schools focus on reproducing cultural, historical, and social norms. Simple solutions are often proposed but they are insufficient to address these complex drivers. Instead it is time to step back and think very differently about medical school admissions. In this Invited Commentary, the author proposes new solutions to address these issues, including: bringing in to the medical school selection process the perspectives of other key stakeholders; increasing collaboration and dialogue across these stakeholder groups; changing the performance metrics by which medical schools are assessed in the global education marketplace; and developing and evaluating new selection processes and tools. Medical schools must engage more reflectively and collaboratively in debates about how to align medical school admissions and meeting the health care needs of the public.

The roles of hospital social workers are delineated in the literature; however, their daily interventions have only been described anecdotally. This study analyzes the daily work of social workers in a pediatric hospital through a survey completed which examined factors related to interventions utilized and time spent per case over a 1-day period. Length and types of interventions were associated with the social determinants of health, time since diagnosis, biopsychosocial issues, and perception of complexity. The study offers a snapshot of the personalized expertise, provided by social workers that addresses complex contextual and biopsychosocial concerns of patient and families.

Thermodynamics of complex structures formed between single-stranded DNA oligomers and the KH domains of the far upstream element binding protein

The noncovalent interaction between protein and DNA is responsible for regulating the genetic activities in living organisms. The most critical issue in this problem is to understand the underlying driving force for the formation and stability of the complex. To address this issue, we have performed atomistic molecular dynamics simulations of two DNA binding K homology (KH) domains (KH3 and KH4) of the far upstream element binding protein (FBP) complexed with two single-stranded DNA (ss-DNA) oligomers in aqueous media. Attempts have been made to calculate the individual components of the net entropy change for the complexation process by adopting suitablemore » statistical mechanical approaches. Our calculations reveal that translational, rotational, and configurational entropy changes of the protein and the DNA components have unfavourable contributions for this protein-DNA association process and such entropy lost is compensated by the entropy gained due to the release of hydration layer water molecules. The free energy change corresponding to the association process has also been calculated using the Free Energy Perturbation (FEP) method. The free energy gain associated with the KH4–DNA complex formation has been found to be noticeably higher than that involving the formation of the KH3–DNA complex.« less

The perspectives, needs and preferences of individuals with complex health and social needs can be overlooked in the design of healthcare interventions. This study was designed to provide new insights on patient perspectives drawing from the qualitative evaluation of 5 complex healthcare interventions. Patients and their caregivers were recruited from 5 interventions based in primary, hospital and community care in Ontario, Canada. We included 62 interviews from 44 patients and 18 non-clinical caregivers. Our team analysed the transcripts from 5 distinct projects. This approach to qualitative meta-evaluation identifies common issues described by a diverse group of patients, therefore providing potential insights into systems issues. This study is a secondary analysis of qualitative data; therefore, no outcome measures were identified. We identified 5 broad themes that capture the patients' experience and highlight issues that might not be adequately addressed in complex interventions. In our study, we found that: (1) the emergency department is the unavoidable point of care; (2) patients and caregivers are part of complex and variable family systems; (3) non-medical issues mediate patients' experiences of health and healthcare delivery; (4) the unanticipated consequences of complex healthcare interventions are often the most valuable; and (5) patient experiences are shaped by the healthcare discourses on medically complex patients. Our findings suggest that key assumptions about patients that inform intervention design need to be made explicit in order to build capacity to better understand and support patients with multiple chronic diseases. Across many health systems internationally, multiple models are being implemented simultaneously that may have shared features and target similar patients, and a qualitative meta-evaluation approach, thus offers an opportunity for cumulative learning at a system level in addition to informing intervention design and modification.

Integer cosine transform for image compression

NASA Technical Reports Server (NTRS)

Cheung, K.-M.; Pollara, F.; Shahshahani, M.

1991-01-01

This article describes a recently introduced transform algorithm called the integer cosine transform (ICT), which is used in transform-based data compression schemes. The ICT algorithm requires only integer operations on small integers and at the same time gives a rate-distortion performance comparable to that offered by the floating-point discrete cosine transform (DCT). The article addresses the issue of implementation complexity, which is of prime concern for source coding applications of interest in deep-space communications. Complexity reduction in the transform stage of the compression scheme is particularly relevant, since this stage accounts for most (typically over 80 percent) of the computational load.

Novel density-based and hierarchical density-based clustering algorithms for uncertain data.

PubMed

Zhang, Xianchao; Liu, Han; Zhang, Xiaotong

2017-09-01

Uncertain data has posed a great challenge to traditional clustering algorithms. Recently, several algorithms have been proposed for clustering uncertain data, and among them density-based techniques seem promising for handling data uncertainty. However, some issues like losing uncertain information, high time complexity and nonadaptive threshold have not been addressed well in the previous density-based algorithm FDBSCAN and hierarchical density-based algorithm FOPTICS. In this paper, we firstly propose a novel density-based algorithm PDBSCAN, which improves the previous FDBSCAN from the following aspects: (1) it employs a more accurate method to compute the probability that the distance between two uncertain objects is less than or equal to a boundary value, instead of the sampling-based method in FDBSCAN; (2) it introduces new definitions of probability neighborhood, support degree, core object probability, direct reachability probability, thus reducing the complexity and solving the issue of nonadaptive threshold (for core object judgement) in FDBSCAN. Then, we modify the algorithm PDBSCAN to an improved version (PDBSCANi), by using a better cluster assignment strategy to ensure that every object will be assigned to the most appropriate cluster, thus solving the issue of nonadaptive threshold (for direct density reachability judgement) in FDBSCAN. Furthermore, as PDBSCAN and PDBSCANi have difficulties for clustering uncertain data with non-uniform cluster density, we propose a novel hierarchical density-based algorithm POPTICS by extending the definitions of PDBSCAN, adding new definitions of fuzzy core distance and fuzzy reachability distance, and employing a new clustering framework. POPTICS can reveal the cluster structures of the datasets with different local densities in different regions better than PDBSCAN and PDBSCANi, and it addresses the issues in FOPTICS. Experimental results demonstrate the superiority of our proposed algorithms over the existing algorithms in accuracy and efficiency. Copyright © 2017 Elsevier Ltd. All rights reserved.

Complex fluid flow in porous media is ubiquitous in many natural and industrial processes. Direct visualization of the fluid structure and flow dynamics is critical for understanding and eventually manipulating these processes. However, the opacity of realistic porous media makes such visualization very challenging. Micromodels, microfluidic model porous media systems, have been developed to address this challenge. They provide a transparent interconnected porous network that enables the optical visualization of the complex fluid flow occurring inside at the pore scale. In this Review, the materials and fabrication methods to make micromodels, the main research activities that are conducted with micromodels and their applications in petroleum, geologic, and environmental engineering, as well as in the food and wood industries, are discussed. The potential applications of micromodels in other areas are also discussed and the key issues that should be addressed in the near future are proposed. © 2018 WILEY-VCH Verlag GmbH & Co.

The deleterious changes in environmental conditions such as water stress bring physiological and biochemical changes in plants, which results in crop loss. Thus, combating water stress is important for crop improvement to manage the needs of growing population. Utilization of hydroponics system in growing plants is questionable to some researchers, as it does not represent an actual field condition. However, trying to address a complex problem like water stress we have to utilize a simpler growing condition like the hydroponics system wherein every input given to the plants can be controlled. With the advent of high-throughput technologies, it is still challenging to address all levels of the genetic machinery whether a gene, protein, metabolite, and promoter. Thus, using a system of reduced complexity like hydroponics can certainly direct us toward the right candidates, if not completely help us to resolve the issue. PMID:26734044

To examine the use and outcomes of balloon-assisted tracking (BAT) technique for dealing with complexities of arm and chest vasculature during transradial approach (TRA) at a single high volume radial center. TRA has been used for coronary angiography and percutaneous coronary interventions (PCI) around the world. Different techniques have been described to address the anatomical issues and tortuosities for successful completion of coronary angiography and PCI. This study describes the use of BAT technique and associated outcomes during real world clinical practice. Subjects comprised 63 patients, (out of total 8,245 patients between January 2011 and December 2012) in whom we encountered significantly complex anatomical course in radial, brachial, or subclavian region, leading to difficult advancement of a diagnostic or a guide catheter despite trying all standard maneuvers. In all of them BAT technique was used and they were retrospectively analyzed for the purpose of this study. About 63 (0.76%) of 8,245 patients met the study criteria. Twenty-five (39.7%) patients had very small RA. Twenty-two (34.9%) had severe RA tortuosity. Four (6.3%) had complex RA loops. Six (9.5%) had severe RA spasm and six (9.5%) had severe subclavian tortuosity and/or stenosis. We encountered technical failure in three (4.8%) patients (two had very small RA and one had 360 degree RA loop). BAT technique was useful to address the anatomical issues and tortuosities of radial, brachial, and subclavian vasculature during TRA. Copyright © 2013 Wiley Periodicals, Inc.

Integrated Approaches to Address the Social Determinants of Health for Reducing Health Inequity

Mitlin, Diana; Mulholland, Catherine; Hardoy, Ana; Stern, Ruth

2007-01-01

The social and physical environments have long since been recognized as important determinants of health. People in urban settings are exposed to a variety of health hazards that are interconnected with their health effects. The Millennium Development Goals (MDGs) have underlined the multidimensional nature of poverty and the connections between health and social conditions and present an opportunity to move beyond narrow sectoral interventions and to develop comprehensive social responses and participatory processes that address the root causes of health inequity. Considering the complexity and magnitude of health, poverty, and environmental issues in cities, it is clear that improvements in health and health equity demand not only changes in the physical and social environment of cities, but also an integrated approach that takes into account the wider socioeconomic and contextual factors affecting health. Integrated or multilevel approaches should address not only the immediate, but also the underlying and particularly the fundamental causes at societal level of related health issues. The political and legal organization of the policy-making process has been identified as a major determinant of urban and global health, as a result of the role it plays in creating possibilities for participation, empowerment, and its influence on the content of public policies and the distribution of scarce resources. This paper argues that it is essential to adopt a long-term multisectoral approach to address the social determinants of health in urban settings. For comprehensive approaches to address the social determinants of health effectively and at multiple levels, they need explicitly to tackle issues of participation, governance, and the politics of power, decision making, and empowerment.

Young, Oran R

2012-02-01

Interacting forces of climate change and globalization are transforming the Arctic. Triggered by a non-linear shift in sea ice, this transformation has unleashed mounting interest in opportunities to exploit the region's natural resources as well as growing concern about environmental, economic, and political issues associated with such efforts. This article addresses the implications of this transformation for governance, identifies limitations of existing arrangements, and explores changes needed to meet new demands. It advocates the development of an Arctic regime complex featuring flexibility across issues and adaptability over time along with an enhanced role for the Arctic Council both in conducting policy-relevant assessments and in promoting synergy in interactions among the elements of the emerging Arctic regime complex. The emphasis throughout is on maximizing the fit between the socioecological features of the Arctic and the character of the governance arrangements needed to steer the Arctic toward a sustainable future.

A review of calibrated blood oxygenation level-dependent (BOLD) methods for the measurement of task-induced changes in brain oxygen metabolism

PubMed Central

Blockley, Nicholas P.; Griffeth, Valerie E. M.; Simon, Aaron B.; Buxton, Richard B.

2013-01-01

The dynamics of the blood oxygenation level-dependent (BOLD) response are dependent on changes in cerebral blood flow, cerebral blood volume and the cerebral metabolic rate of oxygen consumption. Furthermore, the amplitude of the response is dependent on the baseline physiological state, defined by the haematocrit, oxygen extraction fraction and cerebral blood volume. As a result of this complex dependence, the accurate interpretation of BOLD data and robust intersubject comparisons when the baseline physiology is varied are difficult. The calibrated BOLD technique was developed to address these issues. However, the methodology is complex and its full promise has not yet been realised. In this review, the theoretical underpinnings of calibrated BOLD, and issues regarding this theory that are still to be resolved, are discussed. Important aspects of practical implementation are reviewed and reported applications of this methodology are presented. PMID:22945365

Secure messaging (SM) allows patients to communicate with their providers for non-urgent health issues. Like other health information technologies, the design and implementation of SM should account for workflow to avoid suboptimal outcomes. SM may present unique workflow challenges because patients add a layer of complexity, as they are also direct users of the system. This study explores SM implementation at two Veterans Health Administration facilities. We interviewed twenty-nine members of eight primary care teams using semi-structured interviews. Questions addressed staff opinions about the integration of SM with daily practice, and team members' attitudes and experiences with SM. We describe the clinical workflow for SM, examining complexity and variability. We identified eight workflow issues directly related to efficiency and patient satisfaction, based on an exploration of the technology fit with multilevel factors. These findings inform organizational interventions that will accommodate SM implementation and lead to more patient-centered care.

The purpose of this article is to highlight a number of underlying issues that may be useful for a comprehensive review of the management of Health-Related Science, Technology and Innovation policies (ST&I/H), and its strategies and priorities. It is an analytical study supported by an extensive review of the technical and journalistic literature, clippings, legislation and federal government directives. The results show that the Healthcare Production Complex undeniably and increasingly needs science to maintain itself. One may infer that a framework of institutional milestones is being built in Brazil, to strengthen, guide and encourage Research and Development, and that clinical research creates scientific knowledge to address public healthcare issues by generating new inputs or enhancing existing techniques, processes and technologies that will be produced, marketed and used in the different segments, thus feeding the Healthcare Productive Complex.

The human brain is a complex dynamical system generating the EEG signal. Numerical methods developed to study complex physical dynamics have been used to characterize EEG since the mid-eighties. This endeavor raised several issues related to the specificity of EEG. Firstly, theoretical and methodological studies should address the major differences between the dynamics of the human brain and physical systems. Secondly, this approach of EEG signal should prove to be relevant for dealing with physiological or clinical problems. A set of studies performed in our group is presented here within the context of these two problematic aspects. After the discussion of methodological drawbacks, we review numerical simulations related to the high dimension and spatial extension of brain dynamics. Experimental studies in neurologic and psychiatric disease are then presented. We conclude that if it is now clear that brain dynamics changes in relation with clinical situations, methodological problems remain largely unsolved.

Bioinformatics: perspectives for the future.

PubMed

Costa, Luciano da Fontoura

2004-12-30

I give here a very personal perspective of Bioinformatics and its future, starting by discussing the origin of the term (and area) of bioinformatics and proceeding by trying to foresee the development of related issues, including pattern recognition/data mining, the need to reintegrate biology, the potential of complex networks as a powerful and flexible framework for bioinformatics and the interplay between bio- and neuroinformatics. Human resource formation and market perspective are also addressed. Given the complexity and vastness of these issues and concepts, as well as the limited size of a scientific article and finite patience of the reader, these perspectives are surely incomplete and biased. However, it is expected that some of the questions and trends that are identified will motivate discussions during the IcoBiCoBi round table (with the same name as this article) and perhaps provide a more ample perspective among the participants of that conference and the readers of this text.

Management of Complex Cardiac Issues in the Pregnant Patient.

PubMed

Hu, Huayong; Pasca, Ioana

2016-01-01

Management of peripartum heart disease in the intensive care unit requires optimization of maternal hemodynamics and maintenance of fetal perfusion. This requires fetal monitoring and should address the parturient's oxygen saturation, hemoglobin, and cardiac output as it relates to uterine blood flow. Pharmacologic strategies have limited evidence pertaining to hemodynamic stabilization and fetal perfusion. There is some evidence that surgical management of critical mitral stenosis should be percutaneous when possible because cardiac bypass is associated with increased fetal mortality. Fetal monitoring strategies should address central organ perfusion because peripheral scalp pH has not been associated with improved fetal outcomes. Copyright © 2016 Elsevier Inc.

Many papers have dealt with the political difficulties and ramifications of deep nuclear arms reductions, and the issues of “Going to Zero”. Political issues include extended deterrence, conventional weapons, ballistic missile defense, and regional and geo-political security issues. At each step on the road to low numbers, the verification required to ensure compliance of all parties will increase significantly. Looking post New START, the next step will likely include warhead limits in the neighborhood of 1000 . Further reductions will include stepping stones at1000 warheads, 100’s of warheads, and then 10’s of warheads before final elimination could be considered ofmore » the last few remaining warheads and weapons. This paper will focus on these three threshold reduction levels, 1000, 100’s, 10’s. For each, the issues and challenges will be discussed, potential solutions will be identified, and the verification technologies and chain of custody measures that address these solutions will be surveyed. It is important to note that many of the issues that need to be addressed have no current solution. In these cases, the paper will explore new or novel technologies that could be applied. These technologies will draw from the research and development that is ongoing throughout the national laboratory complex, and will look at technologies utilized in other areas of industry for their application to arms control verification.« less

Diabetes and end of life: ethical and methodological issues in gathering evidence to guide care.

PubMed

Dunning, Trisha; Duggan, Nicole; Savage, Sally; Martin, Peter

2013-03-01

Providing palliative care for people with diabetes at the end of life is part of the chronic disease care trajectory, but end of life care is complex and the presence of diabetes further complicates management. The aim of the paper is to discuss the ethical and methodological issues encountered when undertaking research to develop guidelines for managing diabetes at the end of life and the strategies used to address the issues. The issues emerged as we developed guidelines for managing diabetes at the end of life, which included conducting individual interviews with 14 people with diabetes requiring palliative care and 10 family members. A reflexive researcher journal was maintained throughout the guideline development process. The interview transcripts and researcher's journal were analysed to determine key methodological, ethical and researcher-related issues. Key themes were vulnerability of the sampling population, methodological issues included recruiting participants and ensuring rigor, ethical issues concerned benefit and risk, justice, autonomy, privacy, professional boundaries and informed consent. Researcher-related issues were identified such as managing participant distress and their own emotional distress. People were willing to discuss end of life diabetes management preferences. Undertaking research with people at the end of life is complex because of their vulnerability and the ethical issues involved. However, the ethical principles of autonomy and justice apply and people should be given the relevant information and opportunity to decide whether to participate or not. © 2012 The Authors.

Class-first analysis in a continuum: an approach to the complexities of schools, society, and insurgent science

NASA Astrophysics Data System (ADS)

Valdiviezo, Laura Alicia

2010-06-01

This essay addresses Katherine Richardson Bruna's paper: Mexican Immigrant Transnational Social Capital and Class Transformation: Examining the Role of Peer Mediation in Insurgent Science, through five main points . First, I offer a comparison between the traditional analysis of classism in Latin America and Richardson Bruna's call for a class-first analysis in the North American social sciences where there has been a tendency to obviate the specific examination of class relations and class issues. Secondly, I discuss that a class-first analysis solely cannot suffice to depict the complex dimensions in the relations of schools and society. Thus, I suggest a continuum in the class-first analysis. Third, I argue that social constructions surrounding issues of language, ethnicity, and gender necessarily intersect with issues of class and that, in fact, those other constructions offer compatible epistemologies that aid in representing the complexity of social and institutional practices in the capitalist society. Richardson Bruna's analysis of Augusto's interactions with his teacher and peers in the science class provides a fourth point of discussion in this essay. As a final point in my response I discuss Richardson Bruna's idea of making accessible class-first analysis knowledge to educators and especially to science teachers.

Márquez, Samuel

2008-11-01

This special issue of the Anatomical Record explores the presence and diversity of paranasal sinuses in distinct vertebrate groups. The following topics are addressed in particular: dinosaur physiology; development; physiology; adaptation; imaging; and primate systematics. A variety of approaches and techniques are used to examine and characterize the diversity of paranasal sinus pneumatization in a wide spectrum of vertebrates. These range from dissection to histology, from plain X-rays to computer tomography, from comparative anatomy to natural experimental settings, from mathematical computation to computer model simulation, and 2D to 3D reconstructions. The articles in this issue are a combination of literature review and new, hypothesis-driven anatomical research that highlights the complexities of paranasal sinus growth and development; ontogenetic and disease processes; physiology; paleontology; primate systematics; and human evolution. The issue incorporates a wide variety of vertebrates, encompassing a period of over 65 million years, in an effort to offer insight into the diversity of the paranasal sinus complexes through time and space, and thereby providing a greater understanding and appreciation of these special spaces within the cranium.

To explore the practice of experienced stroke nurse researchers to understand the issues they face in recruiting participants. Participant recruitment is one of the greatest challenges in conducting clinical research, with many trials failing due to recruitment problems. Stroke research is a particularly difficult area in which to recruit; however various strategies can improve participation. Analysis revealed three main types of problems for recruiting participants to stroke research: those related to patients, those related to the nurse researcher, and those related to the study itself. Impairments affecting capacity to consent, the acute recruitment time frame of most stroke trials, paternalism by nurse researchers, and low public awareness were especially pertinent. The disabling nature of a stroke, which often includes functional and cognitive impairments, and the acute stage of illness at which patients are appropriate for many trials, make recruiting patients particularly complex and challenging. An awareness of the issues surrounding the recruitment of stroke patients may help researchers in designing and conducting trials. Future work is needed to address the complexities of obtaining informed consent when patient capacity is compromised.

Advances in genetic testing and the availability of such testing in pregnancy allows prospective parents to test their future child for adult-onset conditions. This ability raises several complex ethical issues. Prospective parents have reproductive rights to obtain information about their fetus. This information may or may not alter pregnancy management. These rights can be in conflict with the rights of the future individual, who will be denied the right to elect or decline testing. This paper highlights the complexity of these issues, details discussions that went into the National Society of Genetic Counselors (NSGC) Public Policy Task Force's development of the Prenatal testing for Adult-Onset Conditions position statement adopted in November 2014, and cites relevant literature on this topic through December 2015. Issues addressed include parental rights and autonomy, rights of the future child, the right not to know, possible adverse effects on childhood and the need for genetic counseling. This paper will serve as a reference to genetic counselors and healthcare professionals when faced with this situation in clinical practice.

Predictive monitoring research: Summary of the PREMON system

Doyle, Richard J.; Sellers, Suzanne M.; Atkinson, David J.

1987-01-01

Traditional approaches to monitoring are proving inadequate in the face of two important issues: the dynamic adjustment of expectations about sensor values when the behavior of the device is too complex to enumerate beforehand, and the selective but effective interpretation of sensor readings when the number of sensors becomes overwhelming. This system addresses these issues by building an explicit model of a device and applying common-sense theories of physics to model causality in the device. The resulting causal simulation of the device supports planning decisions about how to efficiently yet reliably utilize a limited number of sensors to verify correct operation of the device.

Economics of Cancer Medicines: For Whose Benefit?

PubMed

Gyawali, Bishal; Sullivan, Richard

2017-04-01

Although new cancer drugs are continually getting approved and used, the value that these drugs add is very debatable. Because of the skyrocketing cost of the new drugs, each new approval represents a multibillion market. However, unlike other branches of economics, cancer drugs are intricately associated with socio-political issues, emotional overlay, public pressure, industry manipulation and propaganda. In this article, we review the value added by new cancer drugs and examine the socio-political agenda around them with highlights on the increasing gulf between high-income and low-middle income countries regarding the affordability to these drugs. Finally, we also suggest a way forward to address this highly complex issue.

Development of a moral judgment measure for veterinary education.

Verrinder, Joy M; Phillips, Clive J C

2014-01-01

Veterinarians increasingly face animal ethics issues, conflicts, and dilemmas, both in practice and in policy, such as the tension between clients' and animals' interests. Little has been done to measure the capacity of veterinarians to make ethical judgments to prevent and address these issues or to identify the effectiveness of strategies to build this capacity. The objectives of this study were, first, to develop a test to identify the capacity of veterinarians to make ethical decisions in relation to animal ethics issues and, second, to assess students' perceptions of the usefulness of three methods for the development of ethical decision making. The Veterinary Defining Issues Test (VetDIT) was piloted with 88 first-year veterinary students at an Australian university. The veterinary students were at a variety of reasoning stages in their use of the Personal Interest (PI), Maintaining Norms (MN), and Universal Principles (UP) reasoning methods in relation to both human ethics and animal ethics issues and operated at a higher level of reasoning for animal than human ethics. Thirty-eight students assessed three methods for developing ethical decision-making skills and identified these as being helpful in clarifying their positions, clarifying others' positions, increasing awareness of the complexity of making ethical decisions, using ethical frameworks and principles, and improving moral reasoning skills, with two methods identified as most helpful. These methods and the VetDIT have the potential to be used as tools for development and assessment of moral judgment in veterinary education to address animal ethics issues.

A Pedagogical Model for Ethical Inquiry into Socioscientific Issues In Science

NASA Astrophysics Data System (ADS)

Saunders, Kathryn J.; Rennie, Léonie J.

2013-02-01

Internationally there is concern that many science teachers do not address socioscientific issues (SSI) in their classrooms, particularly those that are controversial. However with increasingly complex, science-based dilemmas being presented to society, such as cloning, genetic screening, alternative fuels, reproductive technologies and vaccination, there is a growing call for students to be more scientifically literate and to be able to make informed decisions on issues related to these dilemmas. There have been shifts in science curricula internationally towards a focus on scientific literacy, but research indicates that many secondary science teachers lack the support and confidence to address SSI in their classrooms. This paper reports on a project that developed a pedagogical model that scaffolded teachers through a series of stages in exploring a controversial socioscientific issue with students and supported them in the use of pedagogical strategies and facilitated ways of ethical thinking. The study builds on existing frameworks of ethical thinking. It presents an argument that in today's increasingly pluralistic society, these traditional frameworks need to be extended to acknowledge other worldviews and identities. Pluralism is proposed as an additional framework of ethical thinking in the pedagogical model, from which multiple identities, including cultural, ethnic, religious and gender perspectives, can be explored.

MIMO: an efficient tool for molecular interaction maps overlap

PubMed Central

2013-01-01

Background Molecular pathways represent an ensemble of interactions occurring among molecules within the cell and between cells. The identification of similarities between molecular pathways across organisms and functions has a critical role in understanding complex biological processes. For the inference of such novel information, the comparison of molecular pathways requires to account for imperfect matches (flexibility) and to efficiently handle complex network topologies. To date, these characteristics are only partially available in tools designed to compare molecular interaction maps. Results Our approach MIMO (Molecular Interaction Maps Overlap) addresses the first problem by allowing the introduction of gaps and mismatches between query and template pathways and permits -when necessary- supervised queries incorporating a priori biological information. It then addresses the second issue by relying directly on the rich graph topology described in the Systems Biology Markup Language (SBML) standard, and uses multidigraphs to efficiently handle multiple queries on biological graph databases. The algorithm has been here successfully used to highlight the contact point between various human pathways in the Reactome database. Conclusions MIMO offers a flexible and efficient graph-matching tool for comparing complex biological pathways. PMID:23672344

The importance of including dynamic social networks when modeling epidemics of airborne infections: does increasing complexity increase accuracy?

PubMed

Blower, Sally; Go, Myong-Hyun

2011-07-19

Mathematical models are useful tools for understanding and predicting epidemics. A recent innovative modeling study by Stehle and colleagues addressed the issue of how complex models need to be to ensure accuracy. The authors collected data on face-to-face contacts during a two-day conference. They then constructed a series of dynamic social contact networks, each of which was used to model an epidemic generated by a fast-spreading airborne pathogen. Intriguingly, Stehle and colleagues found that increasing model complexity did not always increase accuracy. Specifically, the most detailed contact network and a simplified version of this network generated very similar results. These results are extremely interesting and require further exploration to determine their generalizability.

This paper is concerned with the verification for complex aircraft configurations of an advanced CFD simulation system known by the acronym SAUNA. A brief description of the complete system is given, including its unique use of differing grid generation strategies (structured, unstructured or both) depending on the geometric complexity of the addressed configuration. The majority of the paper focuses on the application of SAUNA to a variety of configurations from the military aircraft, civil aircraft and missile areas. Mesh generation issues are discussed for each geometry and experimental data are used to assess the accuracy of the inviscid (Euler) model used. It is shown that flexibility and accuracy are combined in an efficient manner, thus demonstrating the value of SAUNA in aerodynamic design.

In recent years, we have witnessed substantial progress in the use of clinical informatics systems to support clinicians during episodes of care, manage specialised domain knowledge, perform complex clinical data analysis and improve the management of health organisations' resources. However, the vision of fully integrated health information eco-systems, which provide relevant information and useful knowledge at the point-of-care, remains elusive. This journal Focus Theme reviews some of the enduring challenges of interoperability and complexity in clinical informatics systems. Furthermore, a range of approaches are proposed in order to address, harness and resolve some of the many remaining issues towards a greater integration of health information systems and extraction of useful or new knowledge from heterogeneous electronic data repositories.

Psychosocial Issues in Palliative Care: A Review of Five Cases

PubMed Central

Onyeka, Tonia C

2010-01-01

Palliative care is not just vital in controlling symptoms of the patient’s disease condition, but also aims to extend the patient’s life, giving it a better quality. However, several times in the course of management, the psychosocial impact of cancer, HIV/AIDS, and other life-limiting disease conditions may not be noticed and dealt with during the admission period, thereby giving rise to a more complex situation than the disease condition itself. This article aims to review some psychosocial issues and measures that can be taken to address them. It highlights the various roles and the importance of the clinician, nurse, social worker, and other members of the multidisciplinary team in tackling these issues and will help healthcare professionals in this field achieve better practice in the future.

2016-01-14

The use of non-anonymized human genome data is becoming increasingly popular in research. Here we review the proceedings of a special meeting on this topic that took place at European Molecular Biology Organization (EMBO) in December 2014. The main points discussed centered on how to achieve 'anonymity,' 'trust,' and 'protection of data' in relation to new genomic technologies and research. Following our report of this meeting, we also raise three further issues for future consideration: the harmonization of international law in relation to genetic data protection; the complex issues around the 'dividual' nature of genetic data; and the growing commercial value of personal data. In conclusion, we stress the importance of scientists working in the area of genomic research engaging in interdisciplinary collaborations with humanities and social science scholars and addressing these complicated issues.

Prescription Drug Monitoring Programs: Ethical Issues in the Emergency Department.

Marco, Catherine A; Venkat, Arvind; Baker, Eileen F; Jesus, John E; Geiderman, Joel M

2016-11-01

Prescription drug monitoring programs are statewide databases available to clinicians to track prescriptions of controlled medications. These programs may provide valuable information to assess the history and use of controlled substances and contribute to clinical decisionmaking in the emergency department (ED). The widespread availability of the programs raises important ethical issues about beneficence, nonmaleficence, respect for persons, justice, confidentiality, veracity, and physician autonomy. In this article, we review the ethical issues surrounding prescription drug monitoring programs and how those issues might be addressed to ensure the proper application of this tool in the ED. Clinical decisionmaking in regard to the appropriate use of opioids and other controlled substances is complex and should take into account all relevant clinical factors, including age, sex, clinical condition, medical history, medication history and potential drug-drug interactions, history of addiction or diversion, and disease state.

Pediatric Issues in Return of Results and Incidental Findings: Weighing Autonomy and Best Interests.

PubMed

Holm, Ingrid A

2017-03-01

Nowhere are the ethical issues in genomic research more complex than in pediatrics. Balancing the sometime conflicting autonomy of the parent and the child, and the best interest of the family and the child, brings up many challenging issues. Addressing this balance, especially in the context of the child's developing maturity and comprehension, requires deep analysis and discussion. Issues discussed include the impact of genetic information on the family, parental versus the child's autonomy, the best interests of the child versus the family, potential limitations on the parents' right to know or not know information about their child, and changing role of the developing child in return of research results. Finally, a dynamic model will be proposed that takes into consideration the child's evolving role in consenting and return of results that can be adapted in different national contexts.

BEYOND TEXT: USING ARRAYS TO REPRESENT AND ANALYZE ETHNOGRAPHIC DATA

PubMed Central

Abramson, Corey M.; Dohan, Daniel

2015-01-01

Recent methodological debates in sociology have focused on how data and analyses might be made more open and accessible, how the process of theorizing and knowledge production might be made more explicit, and how developing means of visualization can help address these issues. In ethnography, where scholars from various traditions do not necessarily share basic epistemological assumptions about the research enterprise with either their quantitative colleagues or one another, these issues are particularly complex. Nevertheless, ethnographers working within the field of sociology face a set of common pragmatic challenges related to managing, analyzing, and presenting the rich context-dependent data generated during fieldwork. Inspired by both ongoing discussions about how sociological research might be made more transparent, as well as innovations in other data-centered fields, the authors developed an interactive visual approach that provides tools for addressing these shared pragmatic challenges. They label the approach “ethnoarray” analysis. This article introduces this approach and explains how it can help scholars address widely shared logistical and technical complexities, while remaining sensitive to both ethnography’s epistemic diversity and its practitioners shared commitment to depth, context, and interpretation. The authors use data from an ethnographic study of serious illness to construct a model of an ethnoarray and explain how such an array might be linked to data repositories to facilitate new forms of analysis, interpretation, and sharing within scholarly and lay communities. They conclude by discussing some potential implications of the ethnoarray and related approaches for the scope, practice, and forms of ethnography. PMID:26834296

United States-Mexican Borderlands: Facing tomorrow's challenges through USGS science

Updike, Randall G.; Ellis, Eugene G.; Page, William R.; Parker, Melanie J.; Hestbeck, Jay B.; Horak, William F.

2013-01-01

Along the nearly 3,200 kilometers (almost 2,000 miles) of the United States–Mexican border, in an area known as the Borderlands, we are witnessing the expression of the challenges of the 21st century. This circular identifies several challenge themes and issues associated with life and the environment in the Borderlands, listed below. The challenges are not one-sided; they do not originate in one country only to become problems for the other. The issues and concerns of each challenge theme flow in both directions across the border, and both nations feel their effects throughout the Borderlands and beyond. The clear message is that our two nations, the United States and Mexico, face the issues in these challenge themes together, and the U.S. Geological Survey (USGS) understands it must work with its counterparts, partners, and customers in both countries.Though the mission of the USGS is not to serve as land manager, law enforcer, or code regulator, its innovation and creativity and the scientific and technical depth of its capabilities can be directly applied to monitoring the conditions of the landscape. The ability of USGS scientists to critically analyze the monitored data in search of signals and trends, whether they lead to negative or positive results, allows us to reach significant conclusions—from providing factual conclusions to decisionmakers, to estimating how much of a natural resource exists in a particular locale, to predicting how a natural hazard phenomenon will unfold, to forecasting on a scale from hours to millennia how ecosystems will behave.None of these challenge themes can be addressed strictly by one or two science disciplines; all require well-integrated, cross-discipline thinking, data collection, and analyses. The multidisciplinary science themes that have become the focus of the USGS mission parallel the major challenges in the border region between Mexico and the United States. Because of this multidisciplinary approach, the USGS possesses a unique set of capabilities that can address these challenges. The USGS can apply geographical, geospatial, biological, hydrological, and geological sciences to these complex issues and thereby provide insight into the area’s natural systems and their relation to human activity.As we come to better understand the complexities of the components of these challenge themes, we discover that each part is inextricably intertwined with other overarching issues. Because of the complex interactions of the human, ecological, political, and economic exigencies associated with this area, the status of the Borderlands has become an ever-present concern for most American citizens and for Mexican and United States Federal, State, and local governments. This circular is intended to provide you - citizen, local decisionmaker, government leader, or private entrepreneur—an overview of what the USGS considers the current and future challenges in the United States–Mexican border region and examples of how the USGS can make a difference in understanding and addressing these issues.

Healthcare systems increasingly engage interprofessional healthcare team members such as case managers, social workers, and community health workers to work directly with patients and improve population health. This study elicited perspectives of interprofessional healthcare team members regarding patient barriers to health and suggestions to address these barriers. This is a qualitative study employing focus groups and semi-structured interviews with 39 interprofessional healthcare team members in Philadelphia to elicit perceptions of patients' needs and experiences with the health system, and suggestions for positioning health care systems to better serve patients. Themes were identified using a content analysis approach. Three focus groups and 21 interviews were conducted with 26 hospital-based and 13 ambulatory-based participants. Three domains emerged to characterize barriers to care: social determinants, health system factors, and patient trust in the health system. Social determinants included insurance and financial shortcomings, mental health and substance abuse issues, housing and transportation-related limitations, and unpredictability associated with living in poverty. Suggestions for addressing these barriers included increased financial assistance from the health system, and building a workforce to address these determinants directly. Health care system factors included poor care coordination, inadequate communication of hospital discharge instructions, and difficulty navigating complex systems. Suggestions for addressing these barriers included enhanced communication between care sites, patient-centered scheduling, and improved patient education especially in discharge planning. Finally, factors related to patient trust of the health system emerged. Participants reported that patients are often intimidated by the health system, mistrusting of physicians, and fearful of receiving a serious diagnosis or prognosis. A suggestion for mitigating these issues was increased visibility of the health system within communities to foster trust and help providers gain a better understanding of unique community needs. This work explored interprofessional healthcare team members' perceptions of patient barriers to healthcare engagement. Participants identified barriers related to social determinants of health, complex system organization, and patient mistrust of the health system. Participants offered concrete suggestions to address these barriers, with suggestions supporting current healthcare reform efforts that aim at addressing social determinants and improving health system coordination and adding new insight into how systems might work to improve patient and community trust.

Public health equity in refugee situations

PubMed Central

2011-01-01

Addressing increasing concerns about public health equity in the context of violent conflict and the consequent forced displacement of populations is complex. Important operational questions now faced by humanitarian agencies can to some extent be clarified by reference to relevant ethical theory. Priorities of service delivery, the allocation choices, and the processes by which they are arrived at are now coming under renewed scrutiny in the light of the estimated two million refugees who fled from Iraq since 2003. Operational questions that need to be addressed include health as a relative priority, allocations between and within different populations, and transition and exit strategies. Public health equity issues faced by the humanitarian community can be framed as issues of resource allocation and issues of decision-making. The ethical approach to resource allocation in health requires taking adequate steps to reduce suffering and promote wellbeing, with the upper bound being to avoid harming those at the lower end of the welfare continuum. Deliberations in the realm of international justice have not provided a legal or implementation platform for reducing health disparities across the world, although norms and expectations, including within the humanitarian community, may be moving in that direction. Despite the limitations of applying ethical theory in the fluid, complex and highly political environment of refugee settings, this article explores how this theory could be used in these contexts and provides practical examples. The intent is to encourage professionals in the field, such as aid workers, health care providers, policy makers, and academics, to consider these ethical principles when making decisions.

The evolving role of biosimilars in haematology–oncology: a practical perspective

PubMed Central

Gascon, Pere

2015-01-01

The loss of patents covering many biopharmaceutical/biological agents in the mid 1990s led to the introduction of a new generation of drugs: biosimilars. These new agents, produced by living cells just as the originator drugs, are chemically highly similar to endogenous human proteins; characterized by three-dimensionally complex, high molecular weight compounds. Among the first biosimilars used in haematology–oncology were erythropoietin and granulocyte colony-stimulating factor. After five years of use in clinical practice, the efficacy and safety profile of biosimilars approved by the European Medicines Agency is excellent. Over the next year or two, biosimilar monoclonal antibodies (MoAbs) will become available; the first will be rituximab and trastuzumab. Not only are MoAbs more complex in terms of molecular weight and number of amino acids than the first biosimilars, but they are also anticancer drugs, not merely supportive treatments like their predecessors. This opens up important questions. How are regulatory agencies to assess their clinical efficacy, immunogenicity and safety? Is the neoadjuvant clinical setting the best to evaluate them? What will regulatory agencies decide in terms of switching an originator molecule for a biosimilar or extrapolating efficacy results from one pathology to another? Once biosimilars of rituximab and trastuzumab are approved, several challenging issues will need to be addressed such as how to maintain appropriate pharmacovigilance, how to extrapolate across indications, and issues concerning automatic substitution. There is currently no consensus in any of these areas. This review addresses all these issues: new challenges that the oncology community will face in the near future. PMID:26622996

Addressing increasing concerns about public health equity in the context of violent conflict and the consequent forced displacement of populations is complex. Important operational questions now faced by humanitarian agencies can to some extent be clarified by reference to relevant ethical theory. Priorities of service delivery, the allocation choices, and the processes by which they are arrived at are now coming under renewed scrutiny in the light of the estimated two million refugees who fled from Iraq since 2003.Operational questions that need to be addressed include health as a relative priority, allocations between and within different populations, and transition and exit strategies. Public health equity issues faced by the humanitarian community can be framed as issues of resource allocation and issues of decision-making. The ethical approach to resource allocation in health requires taking adequate steps to reduce suffering and promote wellbeing, with the upper bound being to avoid harming those at the lower end of the welfare continuum. Deliberations in the realm of international justice have not provided a legal or implementation platform for reducing health disparities across the world, although norms and expectations, including within the humanitarian community, may be moving in that direction.Despite the limitations of applying ethical theory in the fluid, complex and highly political environment of refugee settings, this article explores how this theory could be used in these contexts and provides practical examples. The intent is to encourage professionals in the field, such as aid workers, health care providers, policy makers, and academics, to consider these ethical principles when making decisions.

Understanding nutritional epidemiology and its role in policy.

2015-01-01

Nutritional epidemiology has recently been criticized on several fronts, including the inability to measure diet accurately, and for its reliance on observational studies to address etiologic questions. In addition, several recent meta-analyses with serious methodologic flaws have arrived at erroneous or misleading conclusions, reigniting controversy over formerly settled debates. All of this has raised questions regarding the ability of nutritional epidemiologic studies to inform policy. These criticisms, to a large degree, stem from a misunderstanding of the methodologic issues of the field and the inappropriate use of the drug trial paradigm in nutrition research. The exposure of interest in nutritional epidemiology is human diet, which is a complex system of interacting components that cumulatively affect health. Consequently, nutritional epidemiology constantly faces a unique set of challenges and continually develops specific methodologies to address these. Misunderstanding these issues can lead to the nonconstructive and sometimes naive criticisms we see today. This article aims to clarify common misunderstandings of nutritional epidemiology, address challenges to the field, and discuss the utility of nutritional science in guiding policy by focusing on 5 broad questions commonly asked of the field. © 2015 American Society for Nutrition.

Digital telephony analysis model and issues

Keuthan, Lynn M.

1995-09-01

Experts in the fields of digital telephony and communications security have stated the need for an analytical tool for evaluating complex issues. Some important policy issues discussed by experts recently include implementing digital wire-taps, implementation of the 'Clipper Chip', required registration of encryption/decryption keys, and export control of cryptographic equipment. Associated with the implementation of these policies are direct costs resulting from implementation, indirect cost benefits from implementation, and indirect costs resulting from the risks of implementation or factors reducing cost benefits. Presented herein is a model for analyzing digital telephony policies and systems and their associated direct costs and indirect benefit and risk factors. In order to present the structure of the model, issues of national importance and business-related issues are discussed. The various factors impacting the implementation of the associated communications systems and communications security are summarized, and various implementation tradeoffs are compared based on economic benefits/impact. The importance of the issues addressed herein, as well as other digital telephony issues, has greatly increased with the enormous increases in communication system connectivity due to the advance of the National Information Infrastructure.

This article addresses the complex issue of how to clarify conflicts involving value judgments. The author reviews his experiences as therapist, supervisor, and consultant in offering second opinions on in-progress therapies. He summarizes six major obstacles to effective value clarifications and interpretations. Therapists can help patients to explicitly verbalize otherwise only implicit values. Distress from guilt and shame can be reduced by helping a patient reprioritize values and gain self-reflective awareness skills for resolving moral dilemmas.

Using machine-learning methods to analyze economic loss function of quality management processes

NASA Astrophysics Data System (ADS)

Dzedik, V. A.; Lontsikh, P. A.

2018-05-01

During analysis of quality management systems, their economic component is often analyzed insufficiently. To overcome this issue, it is necessary to withdraw the concept of economic loss functions from tolerance thinking and address it. Input data about economic losses in processes have a complex form, thus, using standard tools to solve this problem is complicated. Use of machine learning techniques allows one to obtain precise models of the economic loss function based on even the most complex input data. Results of such analysis contain data about the true efficiency of a process and can be used to make investment decisions.

A Different Trolley Problem: The Limits of Environmental Justice and the Promise of Complex Moral Assessments for Transportation Infrastructure.

PubMed

Epting, Shane

2016-12-01

Transportation infrastructure tremendously affects the quality of life for urban residents, influences public and mental health, and shapes social relations. Historically, the topic is rich with social and political controversy and the resultant transit systems in the United States cause problems for minority residents and issues for the public. Environmental justice frameworks provide a means to identify and address harms that affect marginalized groups, but environmental justice has limits that cannot account for the mainstream population. To account for this condition, I employ a complex moral assessment measure that provides a way to talk about harms that affect the public.

Teaching physics to radiology residents.

PubMed

Hendee, William R

2009-04-01

The complexity of diagnostic imaging has expanded dramatically over the past two decades. Over the same period, the time and effort devoted to teaching physics (the science and technology of the discipline) have diminished. This paradox compromises the ability of future radiologists to master imaging technologies so that they are used in an efficient, safe, and cost-effective manner. This article addresses these issues. Efforts involving many professional organizations are under way to resolve the paradox of the expanding complexity of medical imaging contrasted with the declining emphasis on physics in radiology residency programs. These efforts should help to reestablish physics education as a core value in radiology residency programs.

The complexities of governing in a social media world.

Philpott, Thomas G; Swettenham, Julie

2012-01-01

The complexity of governing has increased with the Internet's introduction of social media. Boards need to be aware of social media impact upon external stakeholder relations, as well as legal responsibilities within the organization. This paper outlines the various implications of social media that a board needs to consider. A governance framework is used to help put the issues in perspective. The conclusion is that boards need to take social media seriously and ensure that their organization has a social media risk mitigation strategy for external communications, as well as eDiscovery. Various other strategies and tactics are suggested to help boards address the challenge.

Physical Therapy in the Treatment of Central Pain Mechanisms for Female Sexual Pain.

Vandyken, Carolyn; Hilton, Sandra

2017-01-01

The complexity of female sexual pain requires an interdisciplinary approach. Physical therapists trained in pelvic health conditions are well positioned to be active members of an interdisciplinary team addressing the assessment and treatment of female sexual pain. Changes within physical therapy practice in the last ten years have resulted in significant utilization of pelvic floor muscle relaxation and manual therapy techniques to address a variety of pelvic pain conditions, including female sexual pain. However, sexual pain is a complex issue giving credence to the necessity of addressing all of the drivers of the pain experience- biological, psychological and social. This review aims to reconcile current pain science with a plan for integrating a biopsychosocial approach into the evaluation and subsequent treatment for female sexual pain for physical therapists. A literature review of the important components of skilled physical therapy interventions is presented including the physical examination, pain biology education, cognitive behavioral influences in treatment design, motivational interviewing as an adjunct to empathetic practice, and the integration of non-threatening movement and mindfulness into treatment. A single case study is used to demonstrate the biopsychosocial framework utilized in this approach. Appropriate measures for assessing psychosocial factors are readily available and inform a reasoned approach for physical therapy design that addresses both peripheral and central pain mechanisms. Decades of research support the integration of a biopsychosocial approach in the treatment of complex pain, including female sexual pain. It is reasonable for physical therapists to utilize evidence based strategies such as CBT, pain biology education, Mindfulness Based Stress Reduction (MBSR), yoga and imagery based exercises to address the biopsychosocial components of female sexual pain.

Buckwalter, K C; Stolley, J M; Farran, C J

1999-11-11

With the aging of society, the incidence of dementia in the elderly is also increasing, and thus results in increased numbers of individuals with cognitive impairment. Nurses and other researchers have investigated issues concerning the management of cognitive impairment. This article highlights conceptual, intervention and methodological issues associated with this phenomenon. Cognitive change is a multivariate construct that includes alterations in a variety of information processing mechanisms such as problem solving ability, memory, perception, attention and learning, and judgement. Although there is a large body of research, conceptual, intervention and methodological issues remain. Much of the clinical research on cognitive impairment is atheoretical, with this issue only recently being addressed. While many clinical interventions have been proposed, few have been adequately tested. There are also various methodological concerns, such as small sample sizes and limited statistical power; study design issues (experimental vs. non-experimental), and internal and external validity problems. Clearly, additional research designed to intervene with these difficult behaviors is needed. A variety of psychosocial, environmental and physical parameters must be considered in the nursing care of persons with cognitive impairment. Special attention has been given to interventions associated with disruptive behaviors. Interventions are complex and knowledge must be integrated from both the biomedical and behavioral sciences in order to deal effectively with the numerous problems that can arise over a long and changing clinical course. Some researchers and clinicians have suggested that a new culture regarding dementia care is needed, one that focuses on changing attitudes and beliefs about persons with dementia and one that changes how organizations deliver that care. This review identifies key conceptual, intervention and methodological issues and recommends how these issues might be addressed in the future.

Vehicular Ad Hoc Networks (VANETs) are considered by car manufacturers and the research community as the enabling technology to radically improve the safety, efficiency and comfort of everyday driving. However, before VANET technology can fulfill all its expected potential, several difficulties must be addressed. One key issue arising when working with VANETs is the complexity of the networking protocols compared to those used by traditional infrastructure networks. Therefore, proper design of the routing strategy becomes a main issue for the effective deployment of VANETs. In this paper, a reliable freestanding position-based routing algorithm (FPBR) for highway scenarios is proposed. For this scenario, several important issues such as the high mobility of vehicles and the propagation conditions may affect the performance of the routing strategy. These constraints have only been partially addressed in previous proposals. In contrast, the design approach used for developing FPBR considered the constraints imposed by a highway scenario and implements mechanisms to overcome them. FPBR performance is compared to one of the leading protocols for highway scenarios. Performance metrics show that FPBR yields similar results when considering freespace propagation conditions, and outperforms the leading protocol when considering a realistic highway path loss model.

Strauss, R P; Broder, H

1985-10-01

The organizational example of a university-based team and two patient case studies illustrate how team interaction affects decision making. The model presented for effective team organization is an egalitarian one. Interdependency, flexibility, and open communication among members are essential. Cleft lip and palate teams provide evaluation and treatment that include input from a variety of professional disciplines. The team context makes it possible for care to be coordinated and alleviates the fragmentation of seeking treatment from several independent specialists. Teams also have a special opportunity to address the complex social and psychological issues prevalent in treating persons with birth defects. Specialists, like psychologists and social workers, identify these issues so that surgeons, dentists, and other clinicians may provide a comprehensive treatment plan and management approach. If psychologists or social workers are not available to a team, the group may still successfully integrate a variety of social and personal factors into their decision making. Examples of problem areas and of issues that may be associated with difficulties in adjusting to cleft therapy are included in this article. Teams that effectively address the psychosocial needs of their patients will enhance patient satisfaction, cooperation, and treatment outcomes.

Faller, H S; Dowell, M A; Jackson, M A

1995-11-01

Healthcare restructuring in the wake of healthcare reform places greater emphasis on primary healthcare. Clinical education in acute care settings and existing community health agencies are not compatible with teaching basic concepts, principles and skills fundamental to nursing. Problems of clients in acute care settings are too complex and clients in the community are often too dispersed for necessary faculty support and supervision of beginning nursing students. Nontraditional learning settings offer the baccalaureate student the opportunity to practice fundamental skills of care and address professional skills of negotiation, assertiveness, organization, collaboration and leadership. An overview of faculty designed clinical learning experiences in nontraditional sites such as McDonald's restaurants, inner city churches, YWCA's, the campus community and homes are presented. The legal, ethical and academic issues associated with nontraditional learning settings are discussed in relation to individual empowerment, decision making and evaluation. Implications for the future address the role of the students and faculty as they interact with the community in which they live and practice.

Current Challenges in Health Economic Modeling of Cancer Therapies: A Research Inquiry

Background The demand for economic models that evaluate cancer treatments is increasing, as healthcare decision makers struggle for ways to manage their budgets while providing the best care possible to patients with cancer. Yet, after nearly 2 decades of cultivating and refining techniques for modeling the cost-effectiveness and budget impact of cancer therapies, serious methodologic and policy challenges have emerged that question the adequacy of economic modeling as a sound decision-making tool in oncology. Objectives We sought to explore some of the contentious issues associated with the development and use of oncology economic models as informative tools in current healthcare decision-making. Our objective was to draw attention to these complex pharmacoeconomic concerns and to promote discussion within the oncology and health economics research communities. Methods Using our combined expertise in health economics research and economic modeling, we structured our inquiry around the following 4 questions: (1) Are economic models adequately addressing questions relevant to oncology decision makers; (2) What are the methodologic limitations of oncology economic models; (3) What guidelines are followed for developing oncology economic models; and (4) Is the evolution of oncology economic modeling keeping pace with treatment innovation? Within the context of each of these questions, we discuss issues related to the technical limitations of oncology modeling, the availability of adequate data for developing models, and the problems with how modeling analyses and results are presented and interpreted. Discussion There is general acceptance that economic models are good, essential tools for decision-making, but the practice of oncology and its rapidly evolving technologies present unique challenges that make assessing and demonstrating value especially complex. There is wide latitude for improvement in oncology modeling methodologies and how model results are presented and interpreted. Conclusion Complex technical and data availability issues with oncology economic modeling pose serious concerns that need to be addressed. It is our hope that this article will provide a framework to guide future discourse on this important topic. PMID:24991399

Achieving the United Nations Sustainable Development Goals in sub-Saharan Africa will require substantial improvements in the coverage and performance of primary health care delivery systems. Projects supported by the Doris Duke Charitable Foundation's (DDCF) African Health Initiative (AHI) created public-private-academic and community partnerships in five African countries to implement and evaluate district-level health system strengthening interventions. In this study, we captured common implementation experiences and lessons learned to understand core elements of successful health systems interventions. We used qualitative data from key informant interviews and annual progress reports from the five Population Health Implementation and Training (PHIT) partnership projects funded through AHI in Ghana, Mozambique, Rwanda, Tanzania, and Zambia. Four major overarching lessons were highlighted. First, variety and inclusiveness of concerned key players (public, academic and private) are necessary to address complex health system issues at all levels. Second, a learning culture that promotes evidence creation and ability to efficiently adapt were key in order to meet changing contextual needs. Third, inclusion of strong implementation science tools and strategies allowed informed and measured learning processes and efficient dissemination of best practices. Fourth, five to seven years was the minimum time frame necessary to effectively implement complex health system strengthening interventions and generate the evidence base needed to advocate for sustainable change for the PHIT partnership projects. The AHI experience has raised remaining, if not overlooked, challenges and potential solutions to address complex health systems strengthening intervention designs and implementation issues, while aiming to measurably accomplish sustainable positive change in dynamic, learning, and varied contexts.

The complexity of biomedical research has increased considerably in the last decade, as has the pace of translational research. This complexity has generated a number of novel ethical issues for clinical investigators, institutional review boards (IRBs), and other oversight committees. In response, many academic medical centers have created formal research ethics consultation (REC) services to help clinical investigators and IRBs navigate ethical issues in biomedical research. Key functions of a REC service include assisting with research design and implementation, providing a forum for deliberative exploration of ethical issues, and supplementing regulatory oversight. As increasing numbers of academic research institutions establish REC services, there is a pressing need for consensus about the primary aims and policies that should guide these activities. Establishing clear expectations about the aims and policies of REC services is important if REC programs are to achieve their full potential. Drawing on the experiences of a Clinical and Translational Science Award Research Ethics Consultation Working Group, this article describes three major ethical and professional practice challenges associated with the provision of REC: (1) managing multiple institutional roles and responsibilities, (2) managing sensitive information, and (3) communicating with consultation requestors about how these issues are managed. The paper also presents several practical strategies for addressing these challenges and enhancing the quality of REC services.

Hartman, Wayne

1991-01-01

The purpose here is to provide a top-level look at the stewardship functions performed in space operations, and to identify the major issues and challenges that must be addressed to build intelligent systems that can realistically support operations functions. The focus is on decision support activities involving monitoring, state assessment, goal generation, plan generation, and plan execution. The bottom line is that problem solving in the space operations domain is a very complex process. A variety of knowledge constructs, representations, and reasoning processes are necessary to support effective human problem solving. Emulating these kinds of capabilities in intelligent systems offers major technical challenges that the artificial intelligence community is only beginning to address.

Advancing efforts to address youth violence involvement.

Weist, M D; Cooley-Quille, M

2001-06-01

Discusses the increased public attention on violence-related problems among youth and the concomitant increased diversity in research. Youth violence involvement is a complex construct that includes violence experienced in multiple settings (home, school, neighborhood) and in multiple forms (as victims, witnesses, perpetrators, and through family members, friends, and the media). Potential impacts of such violence involvement are considerable, including increased internalizing and externalizing behaviors among youth and future problems in school adjustment and life-course development. This introductory article reviews key dimensions of youth-related violence, describes an American Psychological Association Task Force (Division 12) developed to advance relevant research, and presents examples of national resources and efforts that attempt to address this critical public health issue.

2008-05-01

Although many accounts of task switching emphasize the importance of working memory as a substantial source of the switch cost, there is a lack of evidence demonstrating that task switching actually places additional demands on working memory. The present study addressed this issue by implementing task switching in continuous complex span tasks with strictly controlled time parameters. A series of 4 experiments demonstrate that recall performance decreased as a function of the number of task switches and that the concurrent load of item maintenance had no influence on task switching. These results indicate that task switching induces a cost on working memory functioning. Implications for theories of task switching, working memory, and resource sharing are addressed.

The current review explores the complex paths that can lead to adolescent and young adult males becoming sexually abusive. Because sexual abuse is an ongoing issue in our society that is often oversimplified, this article distinguishes between the various risk factors that predict sexually abusive behavior and types of sex offenders, particularly recidivistic offenders. It is imperative to focus on adolescents and young adults who sexually abuse because they represent a particularly important intervention point in preventing sexual abuse in comparison to older age groups and address the importance of differentiating among youths who sexually abuse, particularly between one-time offenders and recidivistic offenders. Implications for addressing these differences are discussed.

The US health care system needs effective tools to address complex social and environmental issues that perpetuate health inequities, such as food insecurity, education and employment barriers, and substandard housing conditions. The medical-legal partnership is a collaborative intervention that embeds civil legal aid professionals in health care settings to address seemingly intractable social problems that contribute to poor health outcomes and health disparities. More than three hundred health care organizations are home to medical-legal partnerships. This article draws upon national survey data and field research to identify three models of the medical-legal partnership that health care organizations have adopted and the core elements of infrastructure that they share. Financing and commitment from health care organizations are key considerations for sustaining and scaling up the medical-legal partnership as a health equity intervention.

Research on damage mechanisms and ultimate strength of composite materials relevant to scaling issues will be addressed in this viewgraph presentation. The use of fracture mechanics and Weibull statistics to predict scaling effects for the onset of isolated damage mechanisms will be highlighted. The ability of simple fracture mechanics models to predict trends that are useful in parametric or preliminary designs studies will be reviewed. The limitations of these simple models for complex loading conditions will also be noted. The difficulty in developing generic criteria for the growth of these mechanisms needed in progressive damage models to predict strength will be addressed. A specific example for a problem where failure is a direct consequence of progressive delamination will be explored. A damage threshold/fail-safety concept for addressing composite damage tolerance will be discussed.

Disparities in access to safe public drinking water are increasingly being recognized as contributing to health disparities and environmental injustice for vulnerable communities in the United States. As the Co-Directors of the Apsaálooke Water and Wastewater Authority (AWWWA) for the Crow Tribe, with our academic partners, we present here the multiple and complex challenges we have addressed in improving and maintaining tribal water and wastewater infrastructure, including the identification of diverse funding sources for infrastructure construction, the need for many kinds of specialized expertise and long-term stability of project personnel, ratepayer difficulty in paying for services, an ongoing legacy of inadequate infrastructure planning, and lack of water quality research capacity. As a tribal entity, the AWWWA faces additional challenges, including the complex jurisdictional issues affecting all phases of our work, lack of authority to create water districts, and additional legal and regulatory gaps-especially with regards to environmental protection. Despite these obstacles, the AWWWA and Crow Tribe have successfully upgraded much of the local water and wastewater infrastructure. We find that ensuring safe public drinking water for tribal and other disadvantaged U.S. communities will require comprehensive, community-engaged approaches across a broad range of stakeholders to successfully address these complex legal, regulatory, policy, community capacity, and financial challenges.

Following an extensive literature search and a consensus conference with subject matter experts the following conclusions can be drawn: 1. Robotic surgery is still at its infancy, and there is a great potential in sophisticated electromechanical systems to perform complex surgical tasks when these systems evolve. 2. To date, in the vast majority of clinical settings, there is little or no advantage in using robotic systems in general surgery in terms of clinical outcome. Dedicated parameters should be addressed, and high quality research should focus on quality of care instead of routine parameters, where a clear advantage is not to be expected. 3. Preliminary data demonstrates that robotic system have a clinical benefit in performing complex procedures in confined spaces, especially in those that are located in unfavorable anatomical locations. 4. There is a severe lack of high quality data on robotic surgery, and there is a great need for rigorously controlled, unbiased clinical trials. These trials should be urged to address the cost-effectiveness issues as well. 5. Specific areas of research should include complex hepatobiliary surgery, surgery for gastric and esophageal cancer, revisional surgery in bariatric and upper GI surgery, surgery for large adrenal masses, and rectal surgery. All these fields show some potential for a true benefit of using current robotic systems. 6. Robotic surgery requires a specific set of skills, and needs to be trained using a dedicated, structured training program that addresses the specific knowledge, safety issues and skills essential to perform this type of surgery safely and with good outcomes. It is the responsibility of the corresponding professional organizations, not the industry, to define the training and credentialing of robotic basic skills and specific procedures. 7. Due to the special economic environment in which robotic surgery is currently employed special care should be taken in the decision making process when deciding on the purchase, use and training of robotic systems in general surgery. 8. Professional organizations in the sub-specialties of general surgery should review these statements and issue detailed, specialty-specific guidelines on the use of specific robotic surgery procedures in addition to outlining the advanced robotic surgery training required to safely perform such procedures.

Feminism and public health ethics

Rogers, W A

2006-01-01

This paper sketches an account of public health ethics drawing upon established scholarship in feminist ethics. Health inequities are one of the central problems in public health ethics; a feminist approach leads us to examine not only the connections between gender, disadvantage, and health, but also the distribution of power in the processes of public health, from policy making through to programme delivery. The complexity of public health demands investigation using multiple perspectives and an attention to detail that is capable of identifying the health issues that are important to women, and investigating ways to address these issues. Finally, a feminist account of public health ethics embraces rather than avoids the inescapable political dimensions of public health. PMID:16731735

Comprehensive Environmental Assessment: A Meta-Assessment Approach

PubMed Central

2012-01-01

With growing calls for changes in the field of risk assessment, improved systematic approaches for addressing environmental issues with greater transparency and stakeholder engagement are needed to ensure sustainable trade-offs. Here we describe the comprehensive environmental assessment (CEA) approach as a holistic way to manage complex information and to structure input from diverse stakeholder perspectives to support environmental decision-making for the near- and long-term. We further note how CEA builds upon and incorporates other available tools and approaches, describe its current application at the U.S. Environmental Protection Agency, and point out how it could be extended in evaluating a major issue such as the sustainability of biofuels.

Nurses should be familiar with and equipped to address the challenges that arise when caring for lesbian, gay, bisexual, transgender, or queer-identified (LGBTQ) patients. LGBTQ individuals have increased rates of certain physical diseases and are at greater risk of suffering from stress-sensitive mental health issues. Negative social attitudes, widespread discrimination and stigma, physical and psychological victimization, and less social support with aging contribute to the complexity of care for these individuals. Open communication, welcoming and accepting attitudes and environments, and sensitivity to unique multidimensional issues improve care to LGBTQ patients with serious advanced illness. Nursing can reach this vulnerable minority and positively impact the quality of care. Copyright © 2016 Elsevier Inc. All rights reserved.

Difede, Joann; Cukor, Judith; Lee, Francis; Yurt, Roger

2009-12-01

Common and pernicious adult psychiatric disorders consequent to burn injury include post-traumatic stress disorder (PTSD), major depressive disorder (MDD), and new-onset substance abuse disorder. Diagnosing and treating these disorders is complicated by the complex psychosocial issues associated with burns including grief, pain, role impairment, disfigurement, dysfunction, stigma, as well as financial and legal issues. Additionally, pre-morbid psychiatric and neurological illnesses are risk factors for burns, adding to the challenge of diagnosis and treatment. This article will focus on the diagnosis and treatment of PTSD and MDD consequent to burn trauma, as these are the major psychiatric outcomes, addressing the attendant psychosocial problems as threads in this post-trauma tapestry.

BIG DATA AND STATISTICS

2016-01-01

Big Data brings unprecedented power to address scientific, economic and societal issues, but also amplifies the possibility of certain pitfalls. These include using purely data-driven approaches that disregard understanding the phenomenon under study, aiming at a dynamically moving target, ignoring critical data collection issues, summarizing or preprocessing the data inadequately and mistaking noise for signal. We review some success stories and illustrate how statistical principles can help obtain more reliable information from data. We also touch upon current challenges that require active methodological research, such as strategies for efficient computation, integration of heterogeneous data, extending the underlying theory to increasingly complex questions and, perhaps most importantly, training a new generation of scientists to develop and deploy these strategies.

Accurate species delimitation underpins good taxonomy. Formalization of integrative taxonomy in the past decade has provided a framework for using multidisciplinary data to make species delimitation hypotheses more rigorous. We address the current state of integrative taxonomy by using as a case study an international project targeted at resolving three important tephritid species complexes: Bactrocera dorsalis complex, Anastrepha fraterculus complex, and Ceratitis FAR (C. fasciventris, C. anonae, C. rosa) complex. The integrative taxonomic approach has helped deliver significant advances in resolving these complexes: It has been used to identify some taxa as belonging to the same biological species as well as to confirm hidden cryptic diversity under a single taxonomic name. Nevertheless, the general application of integrative taxonomy has not been without issue, revealing challenges that must be considered when undertaking an integrative taxonomy project. Scrutiny of this international case study provides a unique opportunity to document lessons learned for the benefit of not only tephritid taxonomists, but also the wider taxonomic community.

Overset grid applications on distributed memory MIMD computers

Chawla, Kalpana; Weeratunga, Sisira

1994-01-01

Analysis of modern aerospace vehicles requires the computation of flowfields about complex three dimensional geometries composed of regions with varying spatial resolution requirements. Overset grid methods allow the use of proven structured grid flow solvers to address the twin issues of geometrical complexity and the resolution variation by decomposing the complex physical domain into a collection of overlapping subdomains. This flexibility is accompanied by the need for irregular intergrid boundary communication among the overlapping component grids. This study investigates a strategy for implementing such a static overset grid implicit flow solver on distributed memory, MIMD computers; i.e., the 128 node Intel iPSC/860 and the 208 node Intel Paragon. Performance data for two composite grid configurations characteristic of those encountered in present day aerodynamic analysis are also presented.

Extending network approach to language dynamics and human cognition. Comment on "Approaching human language with complex networks" by Cong and Liu

2014-12-01

By analyzing complex networks constructed from authentic language data, Cong and Liu [1] advance linguistics research into the big data era. The network approach has revealed many intrinsic generalities and crucial differences at both the macro and micro scales between human languages. The axiom behind this research is that language is a complex adaptive system [2]. Although many lexical, semantic, or syntactic features have been discovered by means of analyzing the static and dynamic linguistic networks of world languages, available network-based language studies have not explicitly addressed the evolutionary dynamics of language systems and the correlations between language and human cognition. This commentary aims to provide some insights on how to use the network approach to study these issues.

The majority of quality measures used to assess providers and hospitals are based on easily obtained data, focused on a few dimensions of quality, and developed mainly for primary/community care and population health. While this approach supports efforts focused on addressing the triple aim of health care, many current quality report cards and assessments do not reflect the breadth or complexity of many referral center practices. In this article, the authors highlight the differences between population health efforts and referral care and address issues related to value measurement and performance assessment. They discuss why measures may need to differ across the three levels of care (primary/community care, secondary care, complex care) and illustrate the need for further risk adjustment to eliminate referral bias. With continued movement toward value-based purchasing, performance measures and reimbursement schemes need to reflect the increased level of intensity required to provide complex care. The authors propose a framework to operationalize value measurement and payment for specialty care, and they make specific recommendations to improve performance measurement for complex patients. Implementing such a framework to differentiate performance measures by level of care involves coordinated efforts to change both policy and operational platforms. An essential component of this framework is a new model that defines the characteristics of patients who require complex care and standardizes metrics that incorporate those definitions.

Pearlman, F.; Coote, A.; Friedl, L.; Stewart, M.

2012-12-01

Geospatial information contributes to decisions by both societal and individual decision-makers. More effective use of this information is essential as issues are increasingly complex and consequences can be critical for future economic and social development. To address this, a workshop brought together analysts, communicators, officials, and researchers from academia, government, non-governmental organizations, and the private sector. A range of policy issues, management needs, and resource requirements were discussed and a wide array of analyses, geospatial data, methods of analysis, and metrics were presented for assessing and communicating the value of geospatial information. It is clear that there are many opportunities for integrating science and engineering disciplines with the social sciences for addressing societal issues that would benefit from using geospatial information and earth observations. However, these collaborations must have outcomes that can be easily communicated to decision makers. This generally requires either succinct quantitative statements of value based on rigorous models and/or user testimonials of actual applications that save real money. An outcome of the workshop is to pursue the development of a community of practice or society that encompasses a wide range of scientific, social, management, and communication disciplines and fosters collaboration across specialties, helping to build trust across social and science aspects. A resource base is also necessary. This presentation will address approaches for creating a shared knowledge database, containing a glossary of terms, reference materials and examples of case studies and the potential applications for benefit analyses.

Primary Health Care (PHC) funding in Australia is complex and fragmented. The focus of PHC funding in Australia has been on volume rather than comprehensive primary care and continuous quality improvement. As PHC in Australia is increasingly delivered by hybrid style organisations, an appropriate funding model that matches this set-up while addressing current issues with PHC funding is required. This article discusses and proposes an appropriate funding model for hybrid PHC organisations.

This paper addresses the issue of obtaining bounds on the real parameter perturbations of a linear state-space model for robust stability. Based on Kronecker algebra, new, easily computable sufficient bounds are derived that are much less conservative than the existing bounds since the technique is meant for only real parameter perturbations (in contrast to specializing complex variation case to real parameter case). The proposed theory is illustrated with application to several flight control examples.

DOE has partnered with the Pacific Northwest National Laboratory (PNNL) on the PHOENIX (PNNL-Hanford Online Environmental Information System) project, which seeks to address data access, transparency, and integration challenges at Hanford to provide effective decision support. PHOENIX is a family of spatially-enabled web applications providing quick access to decades of valuable scientific data and insight through intuitive query, visualization, and analysis tools. PHOENIX realizes broad, public accessibilitymore » by relying only on ubiquitous web-browsers, eliminating the need for specialized software. It accommodates a wide range of users with intuitive user interfaces that require little or no training to quickly obtain and visualize data. Currently, PHOENIX is actively hosting three applications focused on groundwater monitoring, groundwater clean-up performance reporting, and in-tank monitoring. PHOENIX-based applications are being used to streamline investigative and analytical processes at Hanford, saving time and money. But more importantly, by integrating previously isolated datasets and developing relevant visualization and analysis tools, PHOENIX applications are enabling DOE to discover new correlations hidden in legacy data, allowing them to more effectively address complex issues at Hanford.« less

Understanding the structure, functions, activities and dynamics of microbial communities in natural environments is one of the grand challenges of 21st century science. To address this challenge, over the past decade, numerous technologies have been developed for interrogating microbial communities, of which some are amenable to exploratory work (e.g., high-throughput sequencing and phenotypic screening) and others depend on reference genes or genomes (e.g., phylogenetic and functional gene arrays). Here, we provide a critical review and synthesis of the most commonly applied "open-format" and "closed-format" detection technologies. We discuss their characteristics, advantages, and disadvantages within the context of environmental applications and focus on analysis of complex microbial systems, such as those in soils, in which diversity is high and reference genomes are few. In addition, we discuss crucial issues and considerations associated with applying complementary high-throughput molecular technologies to address important ecological questions.

Addressing the determinants of child mental health: intersectionality as a guide to primary health care renewal.

PubMed

McPherson, Charmaine M; McGibbon, Elizabeth A

2010-09-01

Primary health care (PHC) renewal was designed explicitly to attend to the multidimensional factors impacting on health, including the social determinants of health. These determinants are central considerations in the development of integrated, cross-sectoral, and multi-jurisdictional policies such as those that inform models of shared mental health care for children. However, there are complex theoretical challenges in translating these multidimensional issues into policy. One of these is the rarely discussed interrelationships among the social determinants of health and identities such as race, gender, age, sexuality, and social class within the added confluence of geographic contexts. An intersectionality lens is used to examine the complex interrelationships among the factors affecting child mental health and the associated policy challenges surrounding PHC renewal. The authors argue that an understanding of the intersections of social determinants of health, identity, and geography is pivotal in guiding policy-makers as they address child mental health inequities using a PHC renewal agenda.

Critical care nursing. Expanding roles and responsibilities within the community.

PubMed

Bigler, B R

1990-09-01

The health care system in the United States is undergoing many changes, including the return of chronically dependent individuals who are medically fragile to the community's homes and schools. Community-based health care, when compared with hospital care, is more cost effective and is the consumer's preference. The supportive technology to perform skilled therapies is available and recent legislation, although not adequate, provides support. Not only is the community becoming an arena for the provision of more complex care, it is also becoming an arena for addressing ethical issues. The nursing profession is challenged to prepare skilled nurses for the greater independence that is required in community-based practice. Nurses need to become more aware of the authority inherent in their professional role in order to most effectively address and resolve the more complex and often intensive care needs of their clients who are medically fragile and being cared for in the community and to guide their families in the resolution of related ethical dilemmas.

The ethics of socio-ecohydrological catchment management: towards hydrosolidarity

NASA Astrophysics Data System (ADS)

Falkenmark, M.; Folke, Carl

This paper attempts to clarify key biophysical issues and the problems involved in the ethics of socio-ecohydrological catchment management. The issue in managing complex systems is to live with unavoidable change while securing the capacity of the ecohydrological system of the catchment to sustain vital ecological goods and services, aquatic as well as terrestrial, on which humanity depends ultimately. Catchment management oriented to sustainability has to be based on ethical principles: human rights, international conventions, sustaining crucial ecological goods and services, and protecting ecosystem resilience, all of which have water linkages. Many weaknesses have to be identified, assessed and mitigated to improve the tools by which the ethical issues can be addressed and solved:

• a heritage of constraining tunnel vision in both science and management;
• inadequate shortcuts made in modern scientific system analyses (e.g. science addressing sustainability issues);
• simplistic technical-fix approaches to water and ecosystems in land/water/ecosystem management;
• conventional tools for evaluation of scientific quality with its focus on "doing the thing right" rather than "doing the right thing".

The new ethics have to incorporate principles that, on a catchment basis, allow for proper attention to the hungry and poor, upstream and downstream, to descendants, and to sites and habitats that need to be protected.

Current frontiers and future directions of telecoupling research

NASA Astrophysics Data System (ADS)

Liu, J.

2016-12-01

The world has been increasingly interconnected over long distances though processes such as international trade, migration, telecommunication, and disease spread. However, previous studies often focused on socioeconomic or environmental issues of distant processes. While these studies have generated useful information for individual disciplines, integrating socioeconomic and environmental information is essential for holistic understanding of complex global challenges and unbiased decision making to address the challenges. To advance integrated research, the framework of telecoupling (socioeconomic and environmental interactions over distances) has been developed to explicitly address both socioeconomic and environmental issues simultaneously. Although the framework is relatively new, it has already been applied to tackle a variety of globally important issues, such as food security, water resources, energy sustainability, land use, international trade (e.g., food, forest products, energy, wildlife, industrial products), species invasion, investment, ecosystem services, conservation, information dissemination, and tourism. These applications have identified many important research gaps (e.g. spillover systems) and hidden linkages (e.g. feedbacks) among distant areas of the world with profound implications for sustainable development, ecosystem health, and human well-being. While working with telecoupling presents more challenges than focusing only on disciplinary issues, support from funding agencies has helped accelerate research on telecoupling and more efforts are being aimed at framework quantification and operationalization. The presenter will provide an overview of the current frontiers, discuss future research directions, and highlight emerging opportunities and challenges in telecoupling research and governance.

What needs to be done? Occupational therapy responsibilities and challenges regarding human rights.

Galheigo, Sandra Maria

2011-04-01

Addressing human rights issues brings forth ethical and political responsibilities for occupational therapists and requires new epistemological and educational approaches. The way occupational therapists have faced these challenges has depended upon historical, cultural and social contexts. By means of literature review and historical analysis, this paper reflects on how occupational therapists have dealt with human matters issues and on the contemporary changes within the profession. The paper portrays how Latin American occupational therapists have engaged in social transformation by choosing not to transform ethical and political problems into technical matters. Taking into account experiences and views from South Africa, Brazil and Chile, the paper outlines the importance of developing political literacy and interdisciplinary professional/postprofessional education to prepare the new generation of occupational therapists to engage in social transformation. Addressing issues of invisibility and lack of access to human rights, the paper reflects on the need of developing conceptual tools and strategies for change, and discusses the transformations being produced in contemporary occupational therapy. Occupational therapists and scientists need to be attentive to human rights issues. They also need to answer the call for interconnectedness in the present-day complex societies, and engage in networking and a cross-bordering dialogue. Nevertheless, although necessary and welcome, international cooperation requires a permanent exercise of cultural sensitivity, political awareness and self-awareness. © 2011 The Author.

Issues impacting therapeutic outcomes in pediatric patients: an overview.

Kalra, Atin; Goindi, Shishu

2014-01-01

The quest for achieving optimal therapeutic outcomes in pediatric patients has evaded the healthcare professionals for long and often lack of child specific dosage forms and the associated events that follow with it have been considered to be major contributor towards suboptimal outcomes. Consequently, there have been sustained efforts over the years to address this issue with the enactment of legislations like Best Pharmaceutical for Children Act (BPCA), Pediatric Research Equity Act (PREA) and Pediatric Regulation by European Union (EU) to incentivise the participation of pharmaceutical industry towards development of child friendly dosage forms. Initiatives taken in past by organisations like World Health Organisation (WHO) and Drugs for Neglected Diseases Initiative (DNDi) to spur the development of child friendly dosage forms has helped to address issues pertaining to management of Human Immunodeficiency Virus (HIV) and malaria in pediatric patients. Present efforts aimed at developing child friendly dosage forms include oro-dispersible platforms including thin films and mini-tablets. Despite these leaps and advancements in developing better dosage forms for children, lower therapeutic outcomes in pediatric patients continue to remain an unresolved issue because of detrimental effects of additional factors such as parents understanding of label instructions and complexities involved in executing pediatric clinical studies thus requiring a concerted effort from pharmaceutical companies, academic researchers, parents and healthcare providers to work for better treatment outcomes in children.

Academics from diverse disciplines are recognizing not only the procedural ethical issues involved in research, but also the complexity of everyday "micro" ethical issues that arise. While ethical guidelines are being developed for research in aboriginal populations and low-and-middle-income countries, multi-partnered research initiatives examining arts-based interventions to promote social change pose a unique set of ethical dilemmas not yet fully explored. Our research team, comprising health, education, and social scientists, critical theorists, artists and community-activists launched a five-year research partnership on arts-for-social change. Funded by the Social Science and Humanities Research Council in Canada and based in six universities, including over 40 community-based collaborators, and informed by five main field projects (circus with street youth, theatre by people with disabilities, dance for people with Parkinson's disease, participatory theatre with refugees and artsinfused dialogue), we set out to synthesize existing knowledge and lessons we learned. We summarized these learnings into 12 key points for reflection, grouped into three categories: community-university partnership concerns ( n  = 3), dilemmas related to the arts ( n  = 5), and team issues ( n  = 4). In addition to addressing previous concerns outlined in the literature (e.g., related to consent, anonymity, dangerous emotional terrain, etc.), we identified power dynamics (visible and hidden) hindering meaningful participation of community partners and university-based teams that need to be addressed within a reflective critical framework of ethical practice. We present how our team has been addressing these issues, as examples of how such concerns could be approached in community-university partnerships in arts for social change.

Objectives The purpose of this study was to use a qualitative approach to better understand the importance and efficacy of addressing spiritual issues within an interdisciplinary bone marrow transplant clinic from the perspectives of patients and healthcare providers. Setting Participants were recruited from the bone marrow transplant clinic of a large urban outpatient cancer care centre in western Canada. Participants: Focus groups were conducted with patients (n=7) and healthcare providers (n=9) to explore the importance of addressing spiritual issues across the treatment trajectory and to identify factors associated with effectively addressing these needs. Results Data were analysed using the qualitative approach of latent content analysis. Addressing spiritual issues was understood by patients and healthcare providers, as a core, yet under addressed, component of comprehensive care. Both sets of participants felt that addressing basic spiritual issues was the responsibility of all members of the interdisciplinary team, while recognising the need for specialised and embedded support from a spiritual care professional. While healthcare providers felt that the impact of the illness and treatment had a negative effect on patients’ spiritual well-being, patients felt the opposite. Skills, challenges, key time points and clinical indicators associated with addressing spiritual issues were identified. Conclusions Despite a number of conceptual and clinical challenges associated with addressing spiritual issues patients and their healthcare providers emphasised the importance of an integrated approach whereby basic spiritual issues are addressed by members of the interdisciplinary team and by an embedded spiritual care professional, who in addition also provides specialised support. The identification of clinical issues associated with addressing spiritual needs provides healthcare providers with clinical guidance on how to better integrate this aspect of care into their clinical practice, while also identifying acute incidences when a more targeted and specialised approach may be of benefit.

Mixed methods research designs have been recognized as important in addressing complexity and are recommended particularly in the development and evaluation of complex interventions. This article reports a review of studies in palliative care published between 2010 and March 2012 that combine qualitative and quantitative approaches. A synthesis of approaches to mixed methods research taken in 28 examples of published research studies of relevance to palliative and supportive care is provided, using a typology based on a classic categorization put forward in 1992. Mixed-method studies are becoming more frequently employed in palliative care research and resonate with the complexity of the palliative care endeavour. Undertaking mixed methods research requires a sophisticated understanding of the research process and recognition of some of the underlying complexities encountered when working with different traditions and perspectives on issues of: sampling, validity, reliability and rigour, different sources of data and different data collection and analysis techniques.

Selective synthesis of a series of isostructural MIICuI heterobimetallic complexes spontaneously assembled by an unsymmetrical naphthyridine-based ligand.

Nicolay, Amélie; Tilley, T Don

2018-05-31

Metal-metal cooperation is integral to the function of many enzymes and materials, and model complexes hold enormous potential for providing insights into the capabilities of analogous multimetallic cores. However, the selective synthesis of heterobimetallic complexes still presents a significant challenge, especially for systems that hold the metals in close proximity and feature open or reactive coordination sites for both metals. To address this issue, a rigid, naphthyridine-based dinucleating ligand featuring distinct binding environments was synthesized. This ligand enables the selective synthesis of a series of MIICuI bimetallic complexes (M = Mn, Fe, Co, Ni, Cu, Zn), in which each metal center exclusively occupies its preferred binding pocket, from simple chloride salts. The precision of this selectivity is evident from cyclic voltammetry, ESI-MS and anomalous X-ray diffraction measurements. © 2018 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

This paper applies principles and methods from the framework of anticipatory governance to the case of what the National Research Council calls "complex engineered nanomaterials" (CENM). This framework does not aim to generate crystal ball visions or definitive answers, but rather provides guidance for uncovering, understanding, and addressing social, ethical, environmental, and policy issues that stem from emerging technologies. Thus, in anticipation of increased CENM research, CENM products, and their different governance challenges, we aim to lay the groundwork for the anticipatory governance of CENMs by mapping out what—according to the engineers and scientists, we interviewed who are working at the research level of these CENMs—will be the main issues and themes that we need to pay attention to in the near future. The structured interviews focused on three groups of questions: (1) potential and/or actual applications and/or products from the participant's research; (2) environmental health and safety issues pertaining to both the participant's research and CENMs generally; and (3) the future of CENMs. Without a foundational understanding to build on, social scientists, policymakers, and regulatory agencies will be at a loss about how to govern CENMs before they are widely implemented in society.

In recent years, demand to improve child immunization coverage globally, and the development of the latest vaccines and technology has made the vaccine market very complex. The rise in such complexities often gives birth to numerous issues in the vaccine supply chain, which are the primary cause of its poor performance. Figuring out the cause of the performance problem can help you decide how to address it. The goal of the present study is to identify and analyze important issues in the supply chain of basic vaccines required for child immunization in the developing countries. Twenty-five key issues as various factors of the vaccine supply chain have been presented in this paper. Fuzzy MICMAC analysis has been carried out to classify the factors based on their driving and dependence power and to develop a hierarchy based model. Further, the findings have been discussed with the field experts to identify the critical factors. Three factors: better demand forecast, communication between the supply chain members, and proper planning and scheduling have been identified as the critical factors of vaccine supply chain. These factors should be given special care to improve vaccine supply chain performance.

Growing urban populations, combined with environmental challenges, have placed significant pressure on urban planning to supply housing while addressing policy issues such as sustainability, affordability, and liveability. The interrelated nature of these issues, combined with the requirement of evidence-based planning, has made decision-making so complex that urban planners need to combine expertise on energy, water, carbon emissions, transport and economic development along with other bodies of knowledge necessary to make well-informed decisions. This paper presents two geospatial software systems that can assist in the mediation of complexity, by allowing users to assess a variety of planning metrics without expert knowledgemore » in those disciplines. Using Envision and Envision Scenario Planner (ESP), both products of the Greening the Greyfields research project funded by the Cooperative Research Centre for Spatial Information (CRCSI) in Australia, we demonstrate a workflow for identifying potential redevelopment precincts and designing and assessing possible redevelopment scenarios to optimise planning outcomes.« less

Why do patients engage in medical tourism?

PubMed

Runnels, Vivien; Carrera, P M

2012-12-01

Medical tourism is commonly perceived and popularly depicted as an economic issue, both at the system and individual levels. The decision to engage in medical tourism, however, is more complex, driven by patients' unmet need, the nature of services sought and the manner by which treatment is accessed. In order to beneficially employ the opportunities medical tourism offers, and address and contain possible threats and harms, an informed decision is crucial. This paper aims to enhance the current knowledge on medical tourism by isolating the focal content of the decisions that patients make. Based on the existing literature, it proposes a sequential decision-making process in opting for or against medical care abroad, and engaging in medical tourism, including considerations of the required treatments, location of treatment, and quality and safety issues attendant to seeking care. Accordingly, it comments on the imperative of access to health information and the current regulatory environment which impact on this increasingly popular and complex form of accessing and providing medical care.

Many methodological approaches have been used to understand cultural dimensions to maternal health issues. Although a well-designed quantitative survey with a representative sample can provide essential information on trends in behavior, it does not necessarily establish a contextualized understanding of the complexity in which different behaviors occur. This article addresses how contextualized data can be collected in a short time and under conditions in which participants in conflict-affected zones might not have established, or time to establish, trust with the researchers. The solution, the Participatory Ethnographic Evaluation and Research (PEER) approach, is illustrated through a study whereby South Sudanese marginalized women were trained to design research instruments, and collect and analyze qualitative data. PEER overcomes the problem that many ethnographic or participatory approaches face—the extensive time and resources required to develop trusting relationships with the community to understand the local context and the social networks they form.

Hydrology of and Current Monitoring Issues for the Chicago Area Waterway System, Northeastern Illinois

USGS Publications Warehouse

Duncker, James J.; Johnson, Kevin K.

2015-10-28

The Chicago Area Waterway System (CAWS) consists of a combination of natural and manmade channels that form an interconnected navigable waterway of approximately 90-plus miles in the metropolitan Chicago area of northeastern Illinois. The CAWS serves the area as the primary drainage feature, a waterway transportation corridor, and recreational waterbody. The CAWS was constructed by the Metropolitan Water Reclamation District of Greater Chicago (MWRDGC). Completion of the Chicago Sanitary and Ship Canal (initial portion of the CAWS) in 1900 breached a low drainage divide and resulted in a diversion of water from the Lake Michigan Basin. A U.S. Supreme Court decree (Consent Decree 388 U.S. 426 [1967] Modified 449 U.S. 48 [1980]) limits the annual diversion from Lake Michigan. While the State of Illinois is responsible for the diversion, the MWRDGC regulates and maintains water level and water quality within the CAWS by using several waterway control structures. The operation and control of water levels in the CAWS results in a very complex hydraulic setting characterized by highly unsteady flows. The complexity leads to unique gaging requirements and monitoring issues. This report provides a general discussion of the complex hydraulic setting within the CAWS and quantifies this information with examples of data collected at a range of flow conditions from U.S. Geological Survey streamflow gaging stations and other locations within the CAWS. Monitoring to address longstanding issues of waterway operation, as well as current (2014) emerging issues such as wastewater disinfection and the threat from aquatic invasive species, is included in the discussion.

Addressing clients' racism and racial prejudice in individual psychotherapy: Therapeutic considerations.

PubMed

Bartoli, Eleonora; Pyati, Aarti

2009-06-01

Psychotherapists lack clear guidelines regarding how to address clients' racist and prejudicial comments in clinical work. The authors explore the contributions of multicultural, social justice, feminist, and ethical theories to the field of psychotherapy and apply these theories to 2 clinical vignettes in which clients made racially charged statements. These clinical examples highlight the importance of using racial, in addition to traditional, theories to decipher the clinical meanings of racial comments and dynamics in clinical work. The article provides therapeutic conceptualizations regarding how to address clients' racist and prejudicial comments in psychotherapy and elaborates on the complex meanings that might arise from engaging in racially charged discussions with clients depending on the racial composition of the therapeutic dyad. In addition to highlighting how social justice, multicultural, and feminist lenses are necessary to fully understand the meaning of clients' comments, the argument is made that addressing clients' racist and prejudicial comments is at once a clinical and a social justice issue.

Model-based metrics of human-automation function allocation in complex work environments

NASA Astrophysics Data System (ADS)

Kim, So Young

Function allocation is the design decision which assigns work functions to all agents in a team, both human and automated. Efforts to guide function allocation systematically has been studied in many fields such as engineering, human factors, team and organization design, management science, and cognitive systems engineering. Each field focuses on certain aspects of function allocation, but not all; thus, an independent discussion of each does not address all necessary issues with function allocation. Four distinctive perspectives emerged from a review of these fields: technology-centered, human-centered, team-oriented, and work-oriented. Each perspective focuses on different aspects of function allocation: capabilities and characteristics of agents (automation or human), team structure and processes, and work structure and the work environment. Together, these perspectives identify the following eight issues with function allocation: 1) Workload, 2) Incoherency in function allocations, 3) Mismatches between responsibility and authority, 4) Interruptive automation, 5) Automation boundary conditions, 6) Function allocation preventing human adaptation to context, 7) Function allocation destabilizing the humans' work environment, and 8) Mission Performance. Addressing these issues systematically requires formal models and simulations that include all necessary aspects of human-automation function allocation: the work environment, the dynamics inherent to the work, agents, and relationships among them. Also, addressing these issues requires not only a (static) model, but also a (dynamic) simulation that captures temporal aspects of work such as the timing of actions and their impact on the agent's work. Therefore, with properly modeled work as described by the work environment, the dynamics inherent to the work, agents, and relationships among them, a modeling framework developed by this thesis, which includes static work models and dynamic simulation, can capture the issues with function allocation. Then, based on the eight issues, eight types of metrics are established. The purpose of these metrics is to assess the extent to which each issue exists with a given function allocation. Specifically, the eight types of metrics assess workload, coherency of a function allocation, mismatches between responsibility and authority, interruptive automation, automation boundary conditions, human adaptation to context, stability of the human's work environment, and mission performance. Finally, to validate the modeling framework and the metrics, a case study was conducted modeling four different function allocations between a pilot and flight deck automation during the arrival and approach phases of flight. A range of pilot cognitive control modes and maximum human taskload limits were also included in the model. The metrics were assessed for these four function allocations and analyzed to validate capability of the metrics to identify important issues in given function allocations. In addition, the design insights provided by the metrics are highlighted. This thesis concludes with a discussion of mechanisms for further validating the modeling framework and function allocation metrics developed here, and highlights where these developments can be applied in research and in the design of function allocations in complex work environments such as aviation operations.

Projected Impact of Compositional Verification on Current and Future Aviation Safety Risk

Reveley, Mary S.; Withrow, Colleen A.; Leone, Karen M.; Jones, Sharon M.

2014-01-01

The projected impact of compositional verification research conducted by the National Aeronautic and Space Administration System-Wide Safety and Assurance Technologies on aviation safety risk was assessed. Software and compositional verification was described. Traditional verification techniques have two major problems: testing at the prototype stage where error discovery can be quite costly and the inability to test for all potential interactions leaving some errors undetected until used by the end user. Increasingly complex and nondeterministic aviation systems are becoming too large for these tools to check and verify. Compositional verification is a "divide and conquer" solution to addressing increasingly larger and more complex systems. A review of compositional verification research being conducted by academia, industry, and Government agencies is provided. Forty-four aviation safety risks in the Biennial NextGen Safety Issues Survey were identified that could be impacted by compositional verification and grouped into five categories: automation design; system complexity; software, flight control, or equipment failure or malfunction; new technology or operations; and verification and validation. One capability, 1 research action, 5 operational improvements, and 13 enablers within the Federal Aviation Administration Joint Planning and Development Office Integrated Work Plan that could be addressed by compositional verification were identified.

Health IT success and failure: recommendations from literature and an AMIA workshop.

Kaplan, Bonnie; Harris-Salamone, Kimberly D

2009-01-01

With the United States joining other countries in national efforts to reap the many benefits that use of health information technology can bring for health care quality and savings, sobering reports recall the complexity and difficulties of implementing even smaller-scale systems. Despite best practice research that identified success factors for health information technology projects, a majority, in some sense, still fail. Similar problems plague a variety of different kinds of applications, and have done so for many years. Ten AMIA working groups sponsored a workshop at the AMIA Fall 2006 Symposium. It was entitled "Avoiding The F-Word: IT Project Morbidity, Mortality, and Immortality" and focused on this under-addressed problem. PARTICIPANTS discussed communication, workflow, and quality; the complexity of information technology undertakings; the need to integrate all aspects of projects, work environments, and regulatory and policy requirements; and the difficulty of getting all the parts and participants in harmony. While recognizing that there still are technical issues related to functionality and interoperability, discussion affirmed the emerging consensus that problems are due to sociological, cultural, and financial issues, and hence are more managerial than technical. Participants drew on lessons from experience and research in identifying important issues, action items, and recommendations to address the following: what "success" and "failure" mean, what contributes to making successful or unsuccessful systems, how to use failure as an enhanced learning opportunity for continued improvement, how system successes or failures should be studied, and what AMIA should do to enhance opportunities for successes. The workshop laid out a research agenda and recommended action items, reflecting the conviction that AMIA members and AMIA as an organization can take a leadership role to make projects more practical and likely to succeed in health care settings.

Due to the dynamic and complex nature of in-flight fault monitoring and diagnosis, a research effort was undertaken at NASA Langley Research Center to investigate the application of artificial intelligence techniques for improved situational awareness. Under this research effort, concepts were developed and a software architecture was designed to address the complexities of onboard monitoring and diagnosis. This paper describes the implementation of these concepts in a computer program called FaultFinder. The implementation of the monitoring, diagnosis, and interface functions as separate modules is discussed, as well as the blackboard designed for the communication of these modules. Some related issues concerning the future installation of FaultFinder in an aircraft are also discussed.

The purpose of this study is to discuss some problems which arise in heat or mass transfer in complex channels, with special reference to the spacer-filled channels adopted in membrane processes. Among the issues addressed are the consistent definition of local and mean heat or mass transfer coefficients; the influence of the wall boundary conditions; the influence of one-side versus two-side heat/mass transfer. Most of the results discussed were obtained by finite volume CFD simulations concerning heat transfer in Membrane Distillation or mass transfer in Electrodialysis and Reverse Electrodialysis, but many of the conclusions apply also to different processes involving geometrically complex channels

A systematic literature review of such ethical issues supports medical professionalism in nephrology, and offers a solid evidential base for efforts that aim to improve ethical conduct in health care. To identify the full spectrum of clinical ethical issues that can arise for patients with kidney failure in a systematic and transparent manner. A systematic review in Medline (publications in English or German between 2000 and 2014) and Google Books (with no restrictions) was conducted. Ethical issues were identified by qualitative text analysis and normative analysis. The literature review retrieved 106 references that together mentioned 27 ethical issues in clinical care of kidney failure. This set of ethical issues was structured into a matrix consisting of seven major categories and further first and second-order categories. The systematically-derived matrix helps raise awareness and understanding of the complexity of ethical issues in kidney failure. It can be used to identify ethical issues that should be addressed in specific training programs for clinicians, clinical practice guidelines, or other types of policies dealing with kidney failure.

Reflexology is a complex massage intervention, based on the concept that specific areas of the feet (reflex points) correspond to individual internal organs within the body. Reflexologists trained in the popular Ingham reflexology method claim that massage to these points, using massage techniques unique to reflexology, stimulates an increase in blood supply to the corresponding organ. Reflexology researchers face two key methodological challenges that need to be addressed if a specific treatment-related hemodynamic effect is to be scientifically demonstrated. The first is the problem of inconsistent reflexology foot maps; the second is the issue of poor experimental controls. This article proposes a potential experimental solution that we believe can address both methodological challenges and in doing so, allow any specific hemodynamic treatment effect unique to reflexology to experimentally reveal itself.

Computer vision is regarded as one of the most complex and computationally intensive problems. An integrated vision system (IVS) is a system that uses vision algorithms from all levels of processing to perform for a high level application (e.g., object recognition). An IVS normally involves algorithms from low level, intermediate level, and high level vision. Designing parallel architectures for vision systems is of tremendous interest to researchers. Several issues are addressed in parallel architectures and parallel algorithms for integrated vision systems.

2014-01-01

An important issue for temporal planners is the ability to handle temporal uncertainty. Recent papers have addressed the question of how to tell whether a temporal network is Dynamically Controllable, i.e., whether the temporal requirements are feasible in the light of uncertain durations of some processes. We present a fast algorithm for Dynamic Controllability. We also note a correspondence between the reduction steps in the algorithm and the operations involved in converting the projections to dispatchable form. This has implications for the complexity for sparse networks.

Abstraction of an Affective-Cognitive Decision Making Model Based on Simulated Behaviour and Perception Chains

NASA Astrophysics Data System (ADS)

Sharpanskykh, Alexei; Treur, Jan

Employing rich internal agent models of actors in large-scale socio-technical systems often results in scalability issues. The problem addressed in this paper is how to improve computational properties of a complex internal agent model, while preserving its behavioral properties. The problem is addressed for the case of an existing affective-cognitive decision making model instantiated for an emergency scenario. For this internal decision model an abstracted behavioral agent model is obtained, which ensures a substantial increase of the computational efficiency at the cost of approximately 1% behavioural error. The abstraction technique used can be applied to a wide range of internal agent models with loops, for example, involving mutual affective-cognitive interactions.

Being in the moment, showing compassion, being non-judgmental, acknowledging deep emotional challenges without getting stuck: these are mindfulness characteristics important to us as teachers, yet not often included in teacher preparation. These concerns become magnified when we focus on difficult knowledge and thorny issues, like topics related to gender and race. Using a sociocultural framework, we address how mindfulness, heuristics, and other contemplative practices can be adopted to create safe, supporting, and healing spaces for such complex, often emotionally painful discussions. Participant narratives are used extensively to provide a voice to those marginalized or hurt. Drawing from these narratives and their experience in discussing thorny issues, we put forth possible solutions and interventions that can create spaces that encourage and support critical discourse through mindful practices. The development of a heuristic for discussing thorny issues whose characteristics can be adopted by interested teachers and educators to help frame and mediate this type of difficult discussion is an outcome of this research.

Whether your vantage point is that of an office window or a national park, your view undoubtedly encompasses a rich diversity of life forms, all carefully studied or managed by some scientist, resource manager, or planner. A few simple calculations - the number of species, their interrelationships, and the many researchers studying them - and you can easily see the tremendous challenges that the resulting biological data presents to the information and computer science communities. Biological information varies in format and content: it may pertain to a particular species or an entire ecosystem; it can contain land use characteristics, and geospatially referenced information. The complexity and uniqueness of each individual species or ecosystem do not easily lend themselves to today's computer science tools and applications. To address the challenges that the biological enterprise presents, the National Biological Information Infrastructure (NBII) (http://www.nbii.gov) was established in 1993 on the recommendation of the National Research Council (National Research Council 1993). The NBII is designed to address these issues on a national scale, and through international partnerships. This paper discusses current information and computer science efforts within the National Biological Information Infrastructure Program, and future computer science research endeavors that are needed to address the ever-growing issues related to our nation's biological concerns. ?? 2003 by The Haworth Press, Inc.

With the renewed interest in Cartesian gridding methodologies for the ease and speed of gridding complex geometries in addition to the simplicity of the control volumes used in the computations, it has become important to investigate ways of extending the existing Cartesian grid solver functionalities. This includes developing methods of modeling the viscous effects in order to utilize Cartesian grids solvers for accurate drag predictions and addressing the issues related to the distributed memory parallelization of Cartesian solvers. This research presents advances in two areas of interest in Cartesian grid solvers, viscous effects modeling and MPI parallelization. The development of viscous effects modeling using solely Cartesian grids has been hampered by the widely varying control volume sizes associated with the mesh refinement and the cut cells associated with the solid surface. This problem is being addressed by using physically based modeling techniques to update the state vectors of the cut cells and removing them from the finite volume integration scheme. This work is performed on a new Cartesian grid solver, NASCART-GT, with modifications to its cut cell functionality. The development of MPI parallelization addresses issues associated with utilizing Cartesian solvers on distributed memory parallel environments. This work is performed on an existing Cartesian grid solver, CART3D, with modifications to its parallelization methodology.

Introduction to the JPA special issue: Can the Psychodynamic Diagnostic Manual put the complex person back at the center-stage of personality assessment?

Huprich, Steven K; Meyer, Gregory J

2011-03-01

We briefly introduce this special issue, which focuses both on the Psychodynamic Diagnostic Manual (PDM) and the practice of idiographic, depth-oriented personality assessment. The 7 articles in this issue are diverse in scope but all address these 2 important topics. To set the stage, the special issue opens with a description of the history behind, the purposes of, and the steps taken to develop the PDM, and the next article provides a compelling illustration of depth-oriented personality assessment in the context of a long-term course of psychodynamic treatment. The third and fourth articles describe how the PDM model fosters attention to dynamic processes, not just overt symptoms, and they articulate the challenges and benefits of integrating this model into both the revitalized practice of assessment and diagnosis and the research avenues that will evaluate its validity and utility. The fifth article provides a broad overview of interesting experimental research on implicit processes from personality, social, and cognitive psychology, with implications for understanding and assessing dynamic processes. The sixth article illustrates how a PDM-based assessment of an adolescent boy helpfully contributed to his psychodynamic therapy. Finally, the issue closes with an illuminating article describing a PDM-based training model for the graduated development of assessment and diagnosis skills in a doctoral program. Overall, this special issue helps show how the PDM can invigorate multimethod personality assessment by placing the complex idiographic understanding of a person at the center-stage in the assessment process.

Linguistic complex networks: Rationale, application, interpretation, and directions. Reply to comments on "Approaching human language with complex networks"

Amid the enthusiasm for real-world networks of the new millennium, the enquiry into linguistic networks is flourishing not only as a productive branch of the new networks science but also as a promising approach to linguistic research. Although the complex network approach constitutes a potential opportunity to make linguistics a science, the world of linguistics seems unprepared to embrace it. For one thing, linguistics has been largely unaffected by quantitative methods. Those who are accustomed to qualitative linguistic methods may find it hard to appreciate the application of quantitative properties of language such as frequency and length, not to mention quantitative properties of language modeled as networks. With this in mind, in our review [1] we restrict ourselves to the basics of complex networks and the new insights into human language with the application of complex networks. For another, while breaking new grounds and posing new challenges for linguistics, the complex network approach to human language as a new tradition of linguistic research is faced with challenges and unsolved issues of its own. It is no surprise that the comments on our review, especially their skepticism and suggestions, focus on various different aspects of the complex network approach to human language. We are grateful to all the insightful and penetrating comments, which, together with our review, mark a significant impetus to linguistic research from the complex network approach. In this reply, we would like to address four major issues of the complex network approach to human language, namely, a) its theoretical rationale, b) its application in linguistic research, c) interpretation of the results, and d) directions of future research.

It is generally acknowledged that the medium influences the way we communicate and negotiation research directs considerable attention to the impact of different electronic communication modes on the negotiation process and outcomes. Complexity theories offer models and methods that allow the investigation of how pattern and temporal sequences unfold over time in negotiation interactions. By focusing on the dynamic and interactive quality of negotiations as well as the information, choice, and uncertainty contained in the negotiation process, the complexity perspective addresses several issues of central interest in classical negotiation research. In the present study we compare the complexity of the negotiation communication process among synchronous and asynchronous negotiations (IM vs. e-mail) as well as an electronic negotiation support system including a decision support system (DSS). For this purpose, transcripts of 145 negotiations have been coded and analyzed with the Shannon entropy and the grammar complexity. Our results show that negotiating asynchronically via e-mail as well as including a DSS significantly reduces the complexity of the negotiation process. Furthermore, a reduction of the complexity increases the probability of reaching an agreement.

Over more than three decades, The Anthony Nolan Trust (ANT) has provided an unrelated donor (UD) for over 4000 children and adults lacking a suitable family member donor, and has remained at the forefront of developments in haematopoietic stem cell transplantation (HSCT) and bone marrow register management. These three decades have seen major changes in clinical practice of UD-HSCT, including new indications, increased use of alternative haematopoietic cell sources, significant improvement of the outcome as a result of better support care, less-toxic conditioning regimens, and better donor selection, and expansion to older patients with higher comorbidities. In order to foster our goal of improving UD-HSCT availability and outcome in a progressively more complex clinical scenario, a new initiative from ANT was launched in 2005 to convene an experts workshop to address the topical issues in this field. Four consecutive panels addressed factors influencing donor selection and transplant outcome, the use of cord blood, regulatory and accreditation issues, and future developments in this field. This report summarizes the discussions held in this workshop, which will likely develop into a periodic event where transplant clinicians, scientists and registry members will meet to share their experience and vision in the field of UD-HSCT.

As access to healthy food (or lack thereof) could be considered a social justice issue, social workers should be concerned about this issue and willing to collaborate with colleagues of various disciplines to address it. This study was a formative evaluation conducted to understand best practices, recommendations, and feasibility of a social-marketing-based nutrition education program tailored to the needs of adults with limited income. The authors report findings from focus groups conducted with Cooperative Extension Agents (CEAs) and region coordinators (n = 45) and Supplemental Nutrition Assistance Program Education (SNAP-Ed) (n = 69) eligible participants to inform the development of a social marketing nutrition intervention for SNAP-Ed in Georgia. Barriers to healthy eating included cultural preferences, costs of healthy food, lack of time, and lack of availability. Social marketing has a potential to deliver effective and efficient SNAP-Ed targeted to large, limited-resource Georgians. Segmenting the low-income population based on geographical location as well as best methods for outreach can allow tailored messages to meet identified needs, lifestyles, and other variables that make these individuals most likely to respond to the program. Food security and nutrition education are topics of concern for all health care professionals interested in addressing complex health issues of many low-income adults.

Cellular signaling identifiability analysis: a case study.

Roper, Ryan T; Pia Saccomani, Maria; Vicini, Paolo

2010-05-21

Two primary purposes for mathematical modeling in cell biology are (1) simulation for making predictions of experimental outcomes and (2) parameter estimation for drawing inferences from experimental data about unobserved aspects of biological systems. While the former purpose has become common in the biological sciences, the latter is less common, particularly when studying cellular and subcellular phenomena such as signaling-the focus of the current study. Data are difficult to obtain at this level. Therefore, even models of only modest complexity can contain parameters for which the available data are insufficient for estimation. In the present study, we use a set of published cellular signaling models to address issues related to global parameter identifiability. That is, we address the following question: assuming known time courses for some model variables, which parameters is it theoretically impossible to estimate, even with continuous, noise-free data? Following an introduction to this problem and its relevance, we perform a full identifiability analysis on a set of cellular signaling models using DAISY (Differential Algebra for the Identifiability of SYstems). We use our analysis to bring to light important issues related to parameter identifiability in ordinary differential equation (ODE) models. We contend that this is, as of yet, an under-appreciated issue in biological modeling and, more particularly, cell biology. Copyright (c) 2010 Elsevier Ltd. All rights reserved.

Caring for adults with thalassemia in a pediatric world.

Compagno, Laurice M

2005-01-01

Improved technology and medical advances have increased the life span for patients with thalassemia. Therefore, serious consideration must now be given to adult issues such as fertility, employment opportunities, medical insurance, and long-term coping with chronic illness. Since thalassemia is a childhood illness, most adults are seen in pediatric hospitals-often, in centers with a specialty for thalassemia. Compared to a decade ago, many more patients in thalassemia centers are adolescents or older. Unfortunately, pediatric hospitals are not fully equipped to meet the changing and complex needs of adults. Emergency room care, hospital admissions, decentralized care, comprehensive care, and psychosocial issues are current challenges that must be addressed. In this study, six adult patients were asked to keep track of their care for one month to further examine self-care for thalassemia, a high-maintenance disease. From a qualitative perspective, the issues and challenges that adults face are examined and solutions for improved care are discussed.

The study of sex trafficking, prostitution, sex work, and sexual exploitation is associated with many methodological issues and challenges. Researchers' study designs must consider the many safety issues related to this vulnerable and hidden population. Community advisory boards and key stakeholder involvement are essential to study design to increase safety of participants, usefulness of study aims, and meaningfulness of conclusions. Nonrandomized sampling strategies are most often utilized when studying exploited women and girls, which have the capacity to provide rich data and require complex sampling and recruitment methods. This article reviews the current methodological issues when studying this marginalized population as well as strategies to address challenges while working with the community in order to bring about social change. The authors also discuss their own experiences in collaborating with community organizations to conduct research in this field.

2005-01-01

Emergency and abnormal situations occur on flights everyday around the world. They range from minor situations readily managed to extremely serious and highly time-critical situations that deeply challenge the skills of even the most effective crews. How well crews respond to these situations is a function of several interacting sets of issues: (1) the design of non-normal procedures and checklists, (2) design of aircraft systems and automation, (3) specific aspects of the non-normal situation, such as time criticality and complexity of the situation, (4) human performance capabilities and cognitive limitations under high workload and stress, (5) design of training for non-normal situations, (6) philosophies, policies and practices within the industry, and (7) economic and regulatory constraints. Researchers and pilots working on NASA's Emergency and Abnormal Situations project are addressing these issues in a long-range study. In this paper we discuss these issues and illustrate them with examples from recent incidents and accidents.

Integrated health practices: development of a graduate nursing program.

Jossens, Marilyn O R; Ganley, Barbara J

2006-01-01

This article describes pedagogical issues in the development of a graduate nursing program in Integrated Health Practices (IHP), reports early experiences in the program, and asserts the importance of a graduate program in the specialty. The experience is described, and unique pedagogical issues encountered are discussed. While noting the contributions made to health and health care by Western medicine and nursing practice, the authors elaborate on the benefits of integrating western health care with less technological, less invasive, and less expensive holistic approaches. Diverse populations often require attention to specific chronic conditions, rather than to acute conditions, and constitutional requirements for overall health may be influenced by diverse health philosophies and practices. These requirements may be grounded in cultural and religious beliefs that must be incorporated into culturally sensitive plans of care. Clinical nurse specialists in IHP can offer knowledge and leadership to nursing practice, which address these complex, yet subtle health care issues.

Managing bioengineering complexity with AI techniques.

Our capabilities for systematic design and engineering of biological systems are rapidly increasing. Effectively engineering such systems, however, requires the synthesis of a rapidly expanding and changing complex body of knowledge, protocols, and methodologies. Many of the problems in managing this complexity, however, appear susceptible to being addressed by artificial intelligence (AI) techniques, i.e., methods enabling computers to represent, acquire, and employ knowledge. Such methods can be employed to automate physical and informational "routine" work and thus better allow humans to focus their attention on the deeper scientific and engineering issues. This paper examines the potential impact of AI on the engineering of biological organisms through the lens of a typical organism engineering workflow. We identify a number of key opportunities for significant impact, as well as challenges that must be overcome. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

2005-01-01

In this paper computational modeling efforts undertaken at NASA Stennis Space Center in support of rocket engine component testing are discussed. Such analyses include structurally complex cryogenic liquid valves and gas valves operating at high pressures and flow rates. Basic modeling and initial successes are documented, and other issues that make valve modeling at SSC somewhat unique are also addressed. These include transient behavior, valve stall, and the determination of flow patterns in LOX valves. Hexahedral structured grids are used for valves that can be simplifies through the use of axisymmetric approximation. Hybrid unstructured methodology is used for structurally complex valves that have disparate length scales and complex flow paths that include strong swirl, local recirculation zones/secondary flow effects. Hexahedral (structured), unstructured, and hybrid meshes are compared for accuracy and computational efficiency. Accuracy is determined using verification and validation techniques.

Besides their "classical" antigenic peptide-presenting activity, major histocompatibility complex (MHC) class II antigens can activate different cellular functions in immune and nonimmune cells. However, this "nonclassical" role and its functional consequences are still substantially overlooked. In this review, we will focus on these alternative functional properties of MHC class II antigens, to reawaken attention to their present and foreseeable immunobiologic and pathogenetic implications. The main issues that will be addressed concern 1) the role of MHC class II molecules as basic components of exchangeable oligomeric protein complexes with intracellular signaling ability; 2) the nonclassical functions of MHC class II antigens in immune cells; 3) the pathogenetic role of MHC class II antigens in inflammatory/autoimmune and infectious disease; and 4) the functional role of MHC class II antigens in solid malignancies.

On the Use of Parmetric-CAD Systems and Cartesian Methods for Aerodynamic Design

Automated, high-fidelity tools for aerodynamic design face critical issues in attempting to optimize real-life geometry arid in permitting radical design changes. Success in these areas promises not only significantly shorter design- cycle times, but also superior and unconventional designs. To address these issues, we investigate the use of a parmetric-CAD system in conjunction with an embedded-boundary Cartesian method. Our goal is to combine the modeling capabilities of feature-based CAD with the robustness and flexibility of component-based Cartesian volume-mesh generation for complex geometry problems. We present the development of an automated optimization frame-work with a focus on the deployment of such a CAD-based design approach in a heterogeneous parallel computing environment.

HIV/AIDS, Reproductive and Sexual Health, and the Law

The law is a frequently overlooked tool for addressing the complex practical and ethical issues that arise from the HIV/AIDS pandemic. The law intersects with reproductive and sexual health issues and HIV/AIDS in many ways. Well-written and rigorously applied laws could benefit persons living with (or at risk of contracting) HIV/AIDS, particularly concerning their reproductive and sexual health. Access to reproductive health services should be a legal right, and discrimination based on HIV status, which undermines access, should be prohibited. Laws against sexual violence and exploitation, which perpetuate the spread of HIV and its negative effects, should be enforced. Finally, a human rights framework should inform the drafting of laws to more effectively protect health. PMID:18703431

Moving lips versus moving policy: Can scientists figure out how to do both?

Global environmental issues are, well, global. Their complexity and scope make them among the most important issues of our time. Yet they are also among the most difficult to evaluate analytically and to communicate effectively. Scientists, when they choose to communicate with the public or policy makers at all, often find that their messages are often misunderstood, ignored, or simply marginalized, making public communications a less-than rewarding experience. Some methods, however, can prove more effective than others, and in the area of water resources and climate change, two approaches have proven especially effective. The first is to focus on “success stories” as a way to move the discussion from problems to solutions; the second is to focus on regional issues as a way to engage policy makers and the public, for whom the global scope of the challenges may be overwhelming. One additional complexity is how to deal with intentional efforts to obfuscate or misrepresent science. In the climate area, especially, this has long been a challenge, but successful approaches include refusing to let such efforts derail rational policy debates. This requires that scientists understand how science can be misrepresented or misused, and calling attention to such efforts. This presentation will summarize some successful communications efforts in the areas of climate and water from the experience of the Pacific Institute, a leading independent research group addressing these issues.

Reframing and addressing horizontal violence as a workplace quality improvement concern.

Taylor, Rosemary A; Taylor, Steven S

2018-06-27

To reframe horizontal violence as a quality improvement concern. Although the number of studies exploring horizontal violence has increased, evidence supporting the effectiveness of current interventions is weak and the problem persists. Often framed as an individual or interpersonal issue, horizontal violence has been recognized as a complex phenomenon that can only be understood through an examination of social, individual and organizational factors. As such, interventions to address horizontal violence must be applied systemically and address contributions from all sources. This is a discussion paper. This discussion is based on results of a study of nurses' perceptions of horizontal violence and review of the literature. Context is recognized as a contributing factor in human behavior, yet often overlooked in interventions to address horizontal violence. Moving the focus away from the individual and investigating systems contributions to horizontal violence using existing quality improvement frameworks is suggested. To date, efforts to address horizontal violence have not been proven effective. There is a call for a wider application and investigation of interventions. This reframing provides the system level application suggested and would address a broader range of factors contributing to the perpetuation of the phenomenon. © 2018 Wiley Periodicals, Inc.

Statistical issues in the design, conduct and analysis of two large safety studies.

Gaffney, Michael

2016-10-01

The emergence, post approval, of serious medical events, which may be associated with the use of a particular drug or class of drugs, is an important public health and regulatory issue. The best method to address this issue is through a large, rigorously designed safety study. Therefore, it is important to elucidate the statistical issues involved in these large safety studies. Two such studies are PRECISION and EAGLES. PRECISION is the primary focus of this article. PRECISION is a non-inferiority design with a clinically relevant non-inferiority margin. Statistical issues in the design, conduct and analysis of PRECISION are discussed. Quantitative and clinical aspects of the selection of the composite primary endpoint, the determination and role of the non-inferiority margin in a large safety study and the intent-to-treat and modified intent-to-treat analyses in a non-inferiority safety study are shown. Protocol changes that were necessary during the conduct of PRECISION are discussed from a statistical perspective. Issues regarding the complex analysis and interpretation of the results of PRECISION are outlined. EAGLES is presented as a large, rigorously designed safety study when a non-inferiority margin was not able to be determined by a strong clinical/scientific method. In general, when a non-inferiority margin is not able to be determined, the width of the 95% confidence interval is a way to size the study and to assess the cost-benefit of relative trial size. A non-inferiority margin, when able to be determined by a strong scientific method, should be included in a large safety study. Although these studies could not be called "pragmatic," they are examples of best real-world designs to address safety and regulatory concerns. © The Author(s) 2016.

Understanding health inequity in India is a challenge, given the complexity that characterise the lives of its residents. Interpreting constructive action to address health inequity in the country is rare, though much exhorted by the global research community. We critically analysed operational understandings of inequity embedded in convergent actions to address health-related inequalities by stakeholders in varying contexts within the country. Two implementer groups were purposively chosen to reflect on their experiences addressing inequalities in health (and its determinants) in the public sector working in rural areas and in the private non-profit sector working in urban areas. A representing co-author from each group developed narratives around how they operationally defined, monitored, and addressed health inequality in their work. These narratives were content analysed by two other co-authors to draw out common and disparate themes characterising each action context, operational definitions, shifts and changes in strategies and definitions, and outcomes (both intended and unintended). Findings were reviewed by all authors to develop case studies. We theorised that action to address health inequality converges around a unifying theme or pivot, and developed a heuristic that describes the features of this convergence. In one case, the convergence was a single decision-making platform for deliberation around myriad village development issues, while in the other, convergence brought together communities, legal, police, and health system action around one salient health issue. One case emphasized demand generation, the other was focussed on improving quality and supply of services. In both cases, the operationalization of equity broke beyond a biomedical or clinical focus. Dearth of data meant that implementers exercised various strategies to gather it, and to develop interventions - always around a core issue or population. This exercise demonstrated the possibility of constructive engagement between implementers and researchers to understand and theorize action on health equity and the social determinants of health. This heuristic developed may be of use not just for further research, but also for on-going appraisal and design of policy and praxis, both sensitive to and reflective of Indian concerns and understandings.

Bilayer Protograph Codes for Half-Duplex Relay Channels

2013-01-01

Direct to Earth return links are limited by the size and power of lander devices. A standard alternative is provided by a two-hops return link: a proximity link (from lander to orbiter relay) and a deep-space link (from orbiter relay to Earth). Although direct to Earth return links are limited by the size and power of lander devices, using an additional link and a proposed coding for relay channels, one can obtain a more reliable signal. Although significant progress has been made in the relay coding problem, existing codes must be painstakingly optimized to match to a single set of channel conditions, many of them do not offer easy encoding, and most of them do not have structured design. A high-performing LDPC (low-density parity-check) code for the relay channel addresses simultaneously two important issues: a code structure that allows low encoding complexity, and a flexible rate-compatible code that allows matching to various channel conditions. Most of the previous high-performance LDPC codes for the relay channel are tightly optimized for a given channel quality, and are not easily adapted without extensive re-optimization for various channel conditions. This code for the relay channel combines structured design and easy encoding with rate compatibility to allow adaptation to the three links involved in the relay channel, and furthermore offers very good performance. The proposed code is constructed by synthesizing a bilayer structure with a pro to graph. In addition to the contribution to relay encoding, an improved family of protograph codes was produced for the point-to-point AWGN (additive white Gaussian noise) channel whose high-rate members enjoy thresholds that are within 0.07 dB of capacity. These LDPC relay codes address three important issues in an integrative manner: low encoding complexity, modular structure allowing for easy design, and rate compatibility so that the code can be easily matched to a variety of channel conditions without extensive re-optimization. The main problem of half-duplex relay coding can be reduced to the simultaneous design of two codes at two rates and two SNRs (signal-to-noise ratios), such that one is a subset of the other. This problem can be addressed by forceful optimization, but a clever method of addressing this problem is via the bilayer lengthened (BL) LDPC structure. This method uses a bilayer Tanner graph to make the two codes while using a concept of "parity forwarding" with subsequent successive decoding that removes the need to directly address the issue of uneven SNRs among the symbols of a given codeword. This method is attractive in that it addresses some of the main issues in the design of relay codes, but it does not by itself give rise to highly structured codes with simple encoding, nor does it give rate-compatible codes. The main contribution of this work is to construct a class of codes that simultaneously possess a bilayer parity- forwarding mechanism, while also benefiting from the properties of protograph codes having an easy encoding, a modular design, and being a rate-compatible code.

Integrated mixed methods policy analysis for sustainable food systems: trends, challenges and future research.

PubMed

Cuevas, Soledad

Agriculture is a major contributor to greenhouse gas emissions, an important part of which is associated to deforestation and indirect land use change. Appropriate and coherent food policies can play an important role in aligning health, economic and environmental goals. From the point of view of policy analysis, however, this requires multi-sectoral, interdisciplinary approaches which can be highly complex. Important methodological advances in the area are not exempted from limitations and criticism. We argue that there is scope for further developments in integrated quantitative and qualitative policy analysis combining existing methods, including mathematical modelling and stakeholder analysis. We outline methodological trends in the field, briefly characterise integrated mixed methods policy analysis and identify contributions, challenges and opportunities for future research. In particular, this type of approach can help address issues of uncertainty and context-specific validity, incorporate multiple perspectives and help advance meaningful interdisciplinary collaboration in the field. Substantial challenges remain, however, such as the integration of key issues related to non-communicable disease, or the incorporation of a broader range of qualitative approaches that can address important cultural and ethical dimensions of food.

Contemporary policy encourages self-employment and entrepreneurship as a vehicle for empowerment and self-sufficiency among people with disabilities. However, such encouragement raises important citizenship questions concerning the participation of people with intellectual and developmental disabilities (IDD). As an innovative strategy for addressing pressing social and economic problems, "social entrepreneurship" has become a phrase that is gaining momentum in the IDD community--one that carries with it a very distinct history. Although social entrepreneurship holds the potential to be an empowering source of job creation and social innovation, it also has the potential to be used to further disenfranchise this marginalized population. It is crucial that in moving forward society takes care not to perpetuate existing models of oppression, particularly in regard to the social and economic participation of people with IDD. The conceptual tools addressed in this article can inform the way that researchers, policymakers, and practitioners approach complex issues, such as social entrepreneurship, to improve communication among disciplines while retaining an integral focus on rights and social justice by framing this issue within citizenship theory.

Following a community health assessment the Brazos Valley Health Partnership (BVHP) organized to address fragmentation of services and local health needs. This regional partnership employs the fundamental principles of community-based participatory research, fostering an equitable partnership with the aim of building community capacity to address local health issues. This article describes changes in relationships as a result of capacity building efforts in a community-academic partnership. Growth in network structure among organizations is hypothesized to be indicative of less fragmentation of services for residents and increased capacity of the BVHP to collectively address local health issues. Each of the participant organizations responded to a series of questions regarding its relationships with other organizations. Each organization was asked about information sharing, joint planning, resource sharing, and formal agreements with other organizations. The network survey has been administered 3 times between 2004 and 2009. Network density increased for sharing information and jointly planning events. Growth in the complexity of relationships was reported for sharing tangible resources and formal agreements. The average number of ties between organizations as well as the strength of relationships increased. This study provides evidence that the community capacity building efforts within these communities have contributed to beneficial changes in interorganizational relationships. Results from this analysis are useful for understanding how a community partnership's efforts to address access to care can strengthen a community's capacity for future action. Increased collaboration also leads to new assets, resources, and the transfer of knowledge and skills.

Moving Beyond the Theoretical: Medical Students' Desire for Practical, Role-Specific Ethics Training.

Background It has been widely reported that medical trainees experience situations with profound ethical implications during their clinical rotations. To address this most U.S. medical schools include ethics curricula in their undergraduate programs. However, the content of these curricula vary substantially. Our pilot study aimed to discover, from the students' perspective, how ethics pedagogy prepares medical students for clerkship and what gaps might remain. This qualitative study organized focus groups of third- and fourth-year medical students. Participants recounted ethical concerns encountered during clerkship rotations and reflected on how their medical school ethics curriculum informed their responses to these scenarios. Transcripts of the focus group sessions were analyzed using a grounded theory approach to identify common themes that characterized the students' experiences. While students' accounts demonstrated a solid grasp of ethical theory and attunement to ethical concerns presented in the clinic, they also consistently evinced an inability to act on these issues given clerks' particular position in a complex learning hierarchy. Students felt they received too little training in the role-specific application of medical ethics as clinical trainees. We found a desire among trainees for enhanced practical ethics training in preparation for the clerkship phase of medical education. We recommend several strategies that can begin to address these findings. The use of roleplaying with standardized patients can enable students to practice engagement with ethical issues. Conventional ethics courses can focus more on action-based pedagogy and instruction in conflict management techniques. Finally, clear structures for reporting and seeking advice and support for addressing ethical issues can lessen students' apprehension to act on ethical concerns.

Sexual health education is important in addressing the health and social inequalities faced by people with intellectual disabilities. However, provision of health-related advice and education to people with various types and degrees of linguistic and learning difficulties involves addressing complex issues of language and comprehension. This article reports an exploratory study using 2 qualitative methods to examine the delivery of sexual health education to people with intellectual disabilities. Four video-recordings of sexual health education sessions were collected. Conversation analysis was used to examine in detail how such education occurs as a series of interactions between educators and learners. Interviews with 4 educators were carried out and analyzed using thematic analysis. The analysis shows how educators anticipate problems of comprehension and how they respond when there is evidence that a person does not understand the activity or the educational message. This occurs particularly when verbal prompts involve long sentences and abstract concepts. We show a characteristic pattern that arises in these situations, in which both educator and learner jointly produce a superficially correct response. Although interviews allows us some insight into contextual issues, strategy, and aspects of sexual health education that occur outside of the actual teaching sessions, analysis of actual interactions can show us patterns that occur in interactions between educators and learners when comprehension is in question. Addressing how sexual health education is delivered in practice and in detail provides valuable lessons about how such education can be improved. (c) 2015 APA, all rights reserved).

The composite complex span: French validation of a short working memory task.

Most studies in individual differences in the field of working memory research use complex span tasks to measure working memory capacity. Various complex span tasks based on different materials have been developed, and these tasks have proven both reliable and valid; several complex span tasks are often combined to provide a domain-general estimate of working memory capacity with even better psychometric properties. The present work sought to address two issues. Firstly, having participants perform several full-length complex span tasks in succession makes for a long and tedious procedure. Secondly, few complex span tasks have been translated and validated in French. We constructed a French working memory task labeled the Composite Complex Span (CCS). The CCS includes shortened versions of three classic complex span tasks: the reading span, symmetry span, and operation span. We assessed the psychometric properties of the CCS, including test-retest reliability and convergent validity, with Raven's Advanced Progressive Matrices and with an alpha span task; the CCS demonstrated satisfying qualities in a sample of 1,093 participants. This work provides evidence that shorter versions of classic complex span tasks can yield valid working memory estimates. The materials and normative data for the CCS are also included.

Using Complexity Theory to Guide Medical School Evaluations.

Jorm, Christine; Roberts, Chris

Contemporary medical school evaluations are narrow in focus and often do not consider the wider systems implications of the relationship between learning and teaching, research, clinical care, and community engagement. The result is graduates who lack the necessary knowledge and skills for the modern health care system and an educational system that is limited in its ability to learn and change.To address this issue, the authors apply complexity theory to medical school evaluation, using four key factors-nesting, diversity, self-organization, and emergent outcomes. To help medical educators apply this evaluation approach in their own settings, the authors offer two tools-a modified program logic model and sensemaking. In sensemaking, they use the organic metaphor of the medical school as a neuron situated within a complex neural network to enable medical educators to reframe the way they think about program evaluation. The authors then offer practical guidance for applying this model, including describing the example of addressing graduates' engagement in the health care system. The authors consider the input of teachers, the role of culture and curriculum, and the clinical care system in this example.Medical school evaluation is reframed as an improvement science for complex social interventions (medical school is such an intervention) in this model. With complexity theory's focus on emergent outcomes, evaluation takes on a new focus, reimagining medical students as reaching their future potential as change agents, who transform health systems and the lives of patients.

Dealing systematically with ethical issues in amyotrophic lateral sclerosis (ALS) care requires an unbiased awareness of all the relevant ethical issues. The aim of the study was to determine systematically and transparently the full spectrum of ethical issues in ALS care. We conducted a systematic review in Medline and Google Books (restricted to English and German literature published between 1993 and 2014). We applied qualitative text analysis and normative analysis to categorise the spectrum of ethical issues in ALS care. The literature review retrieved 56 references that together mentioned a spectrum of 103 ethical issues in ALS care. The spectrum was structured into six major categories that consist of first and second-order categories of ethical issues. The systematically derived spectrum of ethical issues in ALS care presented in this paper raises awareness and understanding of the complexity of ethical issues in ALS care. It also offers a basis for the systematic development of informational and training materials for health professionals, patients and their relatives, and society as a whole. Finally, it supports a rational and fair selection of all those ethical issues that should be addressed in health policies, position papers and clinical practice guidelines. Further research is needed to identify ways to systematically select the most relevant ethical issues not only in the clinical environment, but also for the development of clinical practice guidelines.

We are developing a set of complex, multimedia-based instructional modules emphasizing technical and scientific issues related to Giant Segmented Mirror Telescope project. The modules" pedagogy will be open-ended and problem-based to promote development of problem-solving skills. Problem- based-learning modules that emphasize work on open-ended complex real world problems are particularly valuable in illustrating and promoting a perspective on the process of science and engineering. Research in this area shows that these kinds of learning experiences are superior to more conventional student training in terms of gains in student learning. The format for the modules will be based on the award-winning multi-media educational Astronomy Village products that present students with a simulated environment: a mountaintop community surrounded by a cluster of telescopes, satellite receivers, and telecommunication towers. A number of "buildings" are found in the Village, such as a library, a laboratory, and an auditorium. Each building contains an array of information sources and computer simulations. Students navigate through their research with a mentor via imbedded video. The first module will be "Observatory Site Selection." Students will use astronomical data, basic weather information, and sky brightness data to select the best site for an observatory. Students will investigate the six GSMT sites considered by the professional site selection teams. Students will explore weather and basic site issues (e.g., roads and topography) using remote sensing images, computational fluid dynamics results, turbulence profiles, and scintillation of the different sites. Comparison of student problem solving with expert problem solving will also be done as part of the module. As part of a site selection team they will have to construct a case and present it on why they chose a particular site. The second module will address aspects of system engineering and optimization for a GSMT-like telescope. Basic system issues will be addressed and studied. These might include various controls issues and optimization issues such as mirror figure, mirror support stability, and wind loading trade-offs. Using system modeling and system optimization results from existing and early GSMT trade studies, we will create a simulation where students are part of an engineering design and optimization team. They will explore the cost/performance/schedule issues associate with the GSMT design.

Science, Practitioners and Faith Communities: using TEK and Faith Knowledge to address climate issues.

Peterson, K.

2017-12-01

Worldview, Lifeway and Science - Communities that are tied to the land or water for their livelihood, and for whom subsistence guides their cultural lifeway, have knowledges that inform their interactions with the environment. These frameworks, sometimes called Traditional Ecological Knowledges (TEK), are based on generations of observations made and shared within lived life-environmental systems, and are tied to practitioners' broader worldviews. Subsistence communities, including Native American tribes, are well aware of the crises caused by climate change impacts. These communities are working on ways to integrate knowledge from their ancient ways with current observations and methods from Western science to implement appropriate adaptation and resilience measures. In the delta region of south Louisiana, the communities hold worldviews that blend TEK, climate science and faith-derived concepts. It is not incongruent for the communities to intertwine conversations from complex and diverse sources, including the academy, to inform their adaptation measures and their imagined solutions. Drawing on over twenty years of work with local communities, science organizations and faith institutions of the lower bayou region of Louisiana, the presenter will address the complexity of traditional communities' work with diverse sources of knowledge to guide local decision-making and to assist outside partners to more effectively address challenges associated with climate change.

Integrating design science theory and methods to improve the development and evaluation of health communication programs.

Neuhauser, Linda; Kreps, Gary L

2014-12-01

Traditional communication theory and research methods provide valuable guidance about designing and evaluating health communication programs. However, efforts to use health communication programs to educate, motivate, and support people to adopt healthy behaviors often fail to meet the desired goals. One reason for this failure is that health promotion issues are complex, changeable, and highly related to the specific needs and contexts of the intended audiences. It is a daunting challenge to effectively influence health behaviors, particularly culturally learned and reinforced behaviors concerning lifestyle factors related to diet, exercise, and substance (such as alcohol and tobacco) use. Too often, program development and evaluation are not adequately linked to provide rapid feedback to health communication program developers so that important revisions can be made to design the most relevant and personally motivating health communication programs for specific audiences. Design science theory and methods commonly used in engineering, computer science, and other fields can address such program and evaluation weaknesses. Design science researchers study human-created programs using tightly connected build-and-evaluate loops in which they use intensive participatory methods to understand problems and develop solutions concurrently and throughout the duration of the program. Such thinking and strategies are especially relevant to address complex health communication issues. In this article, the authors explore the history, scientific foundation, methods, and applications of design science and its potential to enhance health communication programs and their evaluation.

Using the International Society of Physical and Rehabilitation Medicine (ISPRM) as a case in point, the paper describes the complex world societal situation within which non-governmental organizations that address health issues have to operate.This paper describes the complex world societal situation within which non-governmental organizations (NGOs), that are addressing health issues have to operate. In particular, as an international organization in official relation with the World Health Organization (WHO), ISPRM is confronted with a variety of responsibilities and a true world health political mandate. The accompanying rights need to be played out in relation to its own internal member organization and external allies. The theory of the world society and the current situation are briefly reviewed. The role of international NGOs within the world health polity, rehabilitation and Physical and Rehabilitation Medicine (PRM) is highlighted, whilst special emphasis is placed on NGOs in official relation with WHO. Functions, dysfunctions and challenges of international NGOs operating in the health sector are discussed. Against this background, key approaches to enhance ISPRM's political role are analysed. These include transparent and accountable development of the organization, the differentiation between internal and external policy relations, the harmonization of organizational structures and procedures, the consequential use of political structures available to influence WHO's agenda, and the identification of other policy players of major relevance to PRM in order to build strategic alliances with external partners and to enhance ISPRM's membership base.

Partnering to enhance interprofessional service-learning innovations and addictions recovery.

Service-learning programs are reported to benefit students, faculty, higher education institutions, community agencies and the relationships among these groups. An interprofessional service-learning paradigm may strengthen these benefits. Community settings can expose students to social and cultural determinants of health, in addition to those biomedical determinants more commonly addressed in health sciences curricula. These experiences can also enhance student understanding of the complexities underlying treatment and prevention of modern health problems, particularly chronic diseases. The purpose of this initiative was to create and deliver interprofessional service-learning innovations that would enhance student learning and addictions recovery. To address this initiative, the University of Washington's Health Science Partnerships in Interdisciplinary Clinical Education (HSPICE) and the Salvation Army Adult Rehabilitation Center (ARC) began a community-campus partnership in 1997. Innovations took into account student educational objectives established by HSPICE which included: participation in interdisciplinary teams, in conjunction with community partners to identify and reduce population-based health issues, realization and articulation of biases regarding issues faced by the participating community, acquiring an understanding of the broader determinants of health and developing an understanding of why the complexity of population health requires interdisciplinary strategies for cost effectiveness. Findings are reported from evaluations, needs assessments and ongoing feedback of men recovering from addictions, as applied to health education materials and presentations developed for the ARC. Future directions are highlighted, including the need for further research and evaluation efforts aimed at rigorously assessing cost savings and student knowledge, skills and cultural sensitivity, among others.

Deciding about fast and slow decisions.

2014-02-01

Two reports in this issue address the important topic of clinical decision making. Dual process theory has emerged as the dominant model for understanding the complex processes that underlie human decision making. This theory distinguishes between the reflexive, autonomous processes that characterize intuitive decision making and the deliberate reasoning of an analytical approach. In this commentary, the authors address the polarization of viewpoints that has developed around the relative merits of the two systems. Although intuitive processes are typically fast and analytical processes slow, speed alone does not distinguish them. In any event, the majority of decisions in clinical medicine are not dependent on very short response times. What does appear relevant to diagnostic ease and accuracy is the degree to which the symptoms of the disease being diagnosed are characteristic ones. There are also concerns around some methodological issues related to research design in this area of enquiry. Reductionist approaches that attempt to isolate dependent variables may create such artificial experimental conditions that both external and ecological validity are sacrificed. Clinical decision making is a complex process with many independent (and interdependent) variables that need to be separated out in a discrete fashion and then reflected on in real time to preserve the fidelity of clinical practice. With these caveats in mind, the authors believe that research in this area should promote a better understanding of clinical practice and teaching by focusing less on the deficiencies of intuitive and analytical systems and more on their adaptive strengths.

Chemometric classification of casework arson samples based on gasoline content.

2014-02-01

Detection and identification of ignitable liquids (ILs) in arson debris is a critical part of arson investigations. The challenge of this task is due to the complex and unpredictable chemical nature of arson debris, which also contains pyrolysis products from the fire. ILs, most commonly gasoline, are complex chemical mixtures containing hundreds of compounds that will be consumed or otherwise weathered by the fire to varying extents depending on factors such as temperature, air flow, the surface on which IL was placed, etc. While methods such as ASTM E-1618 are effective, data interpretation can be a costly bottleneck in the analytical process for some laboratories. In this study, we address this issue through the application of chemometric tools. Prior to the application of chemometric tools such as PLS-DA and SIMCA, issues of chromatographic alignment and variable selection need to be addressed. Here we use an alignment strategy based on a ladder consisting of perdeuterated n-alkanes. Variable selection and model optimization was automated using a hybrid backward elimination (BE) and forward selection (FS) approach guided by the cluster resolution (CR) metric. In this work, we demonstrate the automated construction, optimization, and application of chemometric tools to casework arson data. The resulting PLS-DA and SIMCA classification models, trained with 165 training set samples, have provided classification of 55 validation set samples based on gasoline content with 100% specificity and sensitivity.

It is generally acknowledged that the medium influences the way we communicate and negotiation research directs considerable attention to the impact of different electronic communication modes on the negotiation process and outcomes. Complexity theories offer models and methods that allow the investigation of how pattern and temporal sequences unfold over time in negotiation interactions. By focusing on the dynamic and interactive quality of negotiations as well as the information, choice, and uncertainty contained in the negotiation process, the complexity perspective addresses several issues of central interest in classical negotiation research. In the present study we compare the complexity of the negotiation communication process among synchronous and asynchronous negotiations (IM vs. e-mail) as well as an electronic negotiation support system including a decision support system (DSS). For this purpose, transcripts of 145 negotiations have been coded and analyzed with the Shannon entropy and the grammar complexity. Our results show that negotiating asynchronically via e-mail as well as including a DSS significantly reduces the complexity of the negotiation process. Furthermore, a reduction of the complexity increases the probability of reaching an agreement.

Interactions across Multiple Stimulus Dimensions in Primary Auditory Cortex.

2016-01-01

Although sensory cortex is thought to be important for the perception of complex objects, its specific role in representing complex stimuli remains unknown. Complex objects are rich in information along multiple stimulus dimensions. The position of cortex in the sensory hierarchy suggests that cortical neurons may integrate across these dimensions to form a more gestalt representation of auditory objects. Yet, studies of cortical neurons typically explore single or few dimensions due to the difficulty of determining optimal stimuli in a high dimensional stimulus space. Evolutionary algorithms (EAs) provide a potentially powerful approach for exploring multidimensional stimulus spaces based on real-time spike feedback, but two important issues arise in their application. First, it is unclear whether it is necessary to characterize cortical responses to multidimensional stimuli or whether it suffices to characterize cortical responses to a single dimension at a time. Second, quantitative methods for analyzing complex multidimensional data from an EA are lacking. Here, we apply a statistical method for nonlinear regression, the generalized additive model (GAM), to address these issues. The GAM quantitatively describes the dependence between neural response and all stimulus dimensions. We find that auditory cortical neurons in mice are sensitive to interactions across dimensions. These interactions are diverse across the population, indicating significant integration across stimulus dimensions in auditory cortex. This result strongly motivates using multidimensional stimuli in auditory cortex. Together, the EA and the GAM provide a novel quantitative paradigm for investigating neural coding of complex multidimensional stimuli in auditory and other sensory cortices.

Protein import and the origin of red complex plastids.

Gould, Sven B; Maier, Uwe-G; Martin, William F

2015-06-15

The number and nature of endosymbioses involving red algal endosymbionts are debated. Gene phylogenies have become the most popular tool to untangle this issue, but they deliver conflicting results. As gene and lineage sampling has increased, so have both the number of conflicting trees and the number of suggestions in the literature for multiple tertiary, and even quaternary, symbioses that might reconcile the tree conflicts. Independent lines of evidence that can address the issue are needed. Here we summarize the mechanism and machinery of protein import into complex red plastids. The process involves protein translocation machinery, known as SELMA, that arose once in evolution, that facilitates protein import across the second outermost of the four plastid membranes, and that is always targeted specifically to that membrane, regardless of where it is encoded today. It is widely accepted that the unity of protein import across the two membranes of primary plastids is strong evidence for their single cyanobacterial origin. Similarly, the unity of SELMA-dependent protein import across the second outermost plastid membrane constitutes strong evidence for the existence of a single red secondary endosymbiotic event at the common origin of all red complex plastids. We furthermore propose that the two outer membranes of red complex plastids are derived from host endoplasmic reticulum in the initial red secondary endosymbiotic event.

Knowledge of general water-flow directions in lake watersheds and how they may change seasonally can help water-quality specialists and lake managers address a variety of water-quality and aquatic habitat protection issues for lakes. Results from this study indicate that ground-water and surface-water interactions at the study lakes are complex, and the ability of the applied techniques to identify ground-water inflow and surface-water outseepage locations varied among the lakes. Measurement of lake-sediment temperatures proved to be a reliable and relatively inexpensive reconnaissance technique that lake managers may apply in complex settings to identify general areas of ground-water inflow and surface-water outseepage.

Conservation biology faces critical challenges that require collaborative approaches, including novel strategies to support interactions among actors in biodiversity conflicts. The goals of this study were to investigate the concept of common ground across multiple issues and to explore its practical application for the support of environmental management. We conceptually defined common ground as the areas of relevance underlying the suite of issues expressed by people regarding environmental management in a particular context. We then empirically tested this in the Calakmul region of Mexico, where the complex socio-historical context and high biodiversity have created environmental management challenges that are now being addressed by a local, multi-stakeholder management board. We conducted 26 open interviews with members of the board and a further round of quantitative prioritisation of issues raised. Using a coding process designed to reveal common ground, we categorized the issues at four levels ranging from coarse to fine (themes, topics, sub-topics and perspectives). We then analysed two levels, topics (n = 14 issues) and sub-topics (n = 51 issues). To do so, we built common ground matrices to identify and analyze common ground among actors and across issues. First, cluster and non-metrical data analyses revealed the diversity of actor positions and the lack of consistent grouping among actors by occupational activity. This demonstrated that focusing on actors' differences might be misleading, and that actors' views were not closely aligned with their roles. Second, we located issues according to their levels of common ground and importance among actors. We showed that by not focusing on single issue conflicts, the identification of common ground across multiple issues can pinpoint synergies. We then proposed a framework for collaboration that prioritizes issues of high importance with greater common ground (e.g. sustainable resource use activities), to support the development of trust and norms of reciprocity among actors, strengthening the potential for future cooperation. By adopting this approach, environmental managers could support the initial stages of collaborative conservation strategies, engaging with other actors to seek common ground, avoid the creation of polarised groups and help effectively manage biodiversity conflicts.

The Importance of Technology Readiness in NASA Earth Venture Missions

NASA Technical Reports Server (NTRS)

Wells, James E.; Komar, George J.

2009-01-01

The first set of Venture-class investigations share the characteristic that the technology should be mature and all investigations must use mature technology that has been modeled or demonstrated in a relevant environment (Technology Readiness Level (TRL) >5). Technology Readiness Levels are a systematic metric/measurement system that supports assessments of the maturity of a particular technology and the consistent comparison of maturity between different types of technology. The TRL is used in NASA technology planning. A major step in the level of fidelity of the technology demonstration follows the completion of TRL 5. At TRL 6, a system or subsystem model or prototype must be demonstrated in a relevant environment (ground or space) representative model or prototype system or system, which would go well beyond ad hoc, "patch-cord," or discrete component level breadboarding. These TRL levels are chosen as target objectives for the Program. The challenge for offerors is that they must identify key aspects (uncertainty, multi subsystem complexity, etc) of the TRL estimate that should be properly explained in a submitted proposal. Risk minimization is a key component of the Earth Venture missions. Experiences of prior airborne missions will be shared. The discussion will address aspects of uncertainty and issues surrounding three areas of airborne earth science missions: (1) Aircraft or proposed flight platform -- Expressing the capability of the aircraft in terms of the supporting mission requirements. These issues include airplane performance characteristics (duration, range, altitude, among others) and multiship complexities. (2) Instruments -- Establishing that the instruments have been demonstrated in a relevant environment. Instruments with heritage in prior space missions meet this requirement, as do instruments tested on the ground. Evidence that the instruments have demonstrated the ability to collect data as advertised will be described. The complexity of the integration of multiple subsystems will also be addressed. Issues associated with tailoring the instrument to meet the specific Venture mission objectives must be thoroughly explained and justified. (3) Aircraft/Instrument Integration -- Explicitly defining what development may be required to harden the instrument and integrate the instrument. The challenges associated with this key aspect of major airborne earth science investigations will be presented.

2012-02-01

To provide a broad overview of methodological issues in the design and evaluation of intervention studies in dental public health, with particular emphasis on explanatory trials, pragmatic trials and complex interventions. We present a narrative summary of selected publications from the literature outlining both historical and recent challenges in the design and evaluation of intervention studies and describe some recent tools that may help researchers to address these challenges. It is now recognised that few intervention studies in dental public health are purely explanatory or pragmatic. We describe the PRECIS tool which can be used by trialists to assess and display the position of their trial on a continuum between the extremes of explanatory and pragmatic trials. The tool aims to help trialists make design decisions that are in line with their stated aims. The increasingly complex nature of dental public health interventions presents particular design and evaluation challenges. The revised Medical Research Council (MRC) guidance for the development and evaluation of complex interventions which emphasises the importance of planning and process evaluation is a welcome development. We briefly describe the MRC guidance and outline some examples of complex interventions in the field of oral health. The role of observational studies in monitoring public health interventions when the conduct of RCTs is not appropriate or feasible is acknowledged. We describe the STROBE statement and outline the implications of the STROBE guidelines for dental public health. The methodological challenges in the design, conduct and reporting of intervention studies in oral health are considerable. The need to provide reliable evidence to support innovative new strategies in oral health policy is a major impetus in these fields. No doubt the 'Methodological Issues in Oral Health Research' group will have further opportunities to highlight this work. © 2012 John Wiley & Sons A/S.

A comparative analysis of policies addressing rural oral health in eight English-speaking OECD countries.

Oral health is fundamental to overall health. Poor oral health is largely preventable but unacceptable inequalities exist, particularly for people in rural areas. The issues are complex. Rural populations are characterised by lower rates of health insurance, higher rates of poverty, less water fluoridation, fewer dentists and oral health specialists, and greater distances to access care. These factors inter-relate with educational, attitudinal, and system-level issues. An important area of enquiry is whether and how national oral health policies address causes and solutions for poor rural oral health. The purpose of this study was to examine a series of government policies on oral health to (i) determine the extent to which such policies addressed rural oral health issues, and (ii) identify enabling assumptions in policy language about problems and solutions regarding rural communities. Eight current oral health policies were identified from Australia, New Zealand, Canada, the USA, England, Scotland, Northern Ireland, and Wales. Validated content and critical discourse analyses were used to document and explore the concepts in these policy documents, with a particular focus on the frequency with which rural oral health was mentioned, and the enabling assumptions in policy language about rural communities. Seventy-three concepts relating to oral health were identified from the textual analysis of the eight policy documents. The rural concept addressing oral health issues occurred in only 2% of all policies and was notably absent from the oral health policies of countries with substantial rural populations. It occurred most frequently in the policy documents from Australia and Scotland, less so in the policy documents from Canada, Wales, and New Zealand, and not at all in the oral health policies from the US, England, and Northern Ireland. Thus, the oral health needs of rural communities were generally not the focus of, nor included in, the oral health policy documents in this study. When the language of concepts related to rural oral health was examined, the qualitative analysis identified four discourse themes related to both causality and solutions. These ranked discourse themes focused on service models, workforce issues, social determinants of health, and prevention. None of the policies addressed the structural economic determinants of unequal rural oral health, nor did they specifically assert the rights of children in rural communities to equitable oral health care. This study documented the limited focus on rural oral health that existed in national oral health policies from eight different English-speaking countries. It supports the need for an increased focus on rural oral health issues in oral health policies, particularly as increased oral health is clearly associated with increased general health. It speaks to the critical importance of periodic analysis of the content of oral health policies to ensure that issues of inequality are addressed. Further, it reinforces the need for research findings about effective oral health care to be translated into practice in the development of practical and financially viable policies to make access to oral health care more equitable, particularly for people living in rural and remote areas.

The purpose of this study was to describe the patient safety culture of en route care in the United States Air Force aeromedical evacuation system. Almost 100,000 patients have been transported since 2001. Safety concerns in this unique environment are complex because of the extraordinary demands of multitasking, time urgency, long duty hours, complex handoffs, and multiple stressors of flight. An internet-based survey explored the perceptions and experiences of safety issues among nursing personnel involved throughout the continuum of aeromedical evacuation care. A convenience sample of 236 nurses and medical technicians from settings representing the continuum was studied. Descriptive and nonparametric statistics were used to analyze the quantitative data, and thematic analysis was applied to the qualitative data. Results indicate that over 90% of respondents agree or strongly agree safety is a priority in their unit and that their unit is responsive to patient safety initiatives. Many respondents described safety incidents or near misses, and these have been categorized as personnel physical capability limitations, environmental threats, medication and equipment issues, and care process problems. Results suggest the care of patients during transport is influenced by the safety culture, human factors, training, experience, and communication. Suggestions to address safety issues emerged from the survey data. Reprint & Copyright © 2014 Association of Military Surgeons of the U.S.

Covering: 2006 to 2018Phytochemicals are important sources for the discovery and development of agricultural and pharmaceutical compounds, such as pesticides and medicines. However, these compounds are typically present in low abundance in nature, and the biosynthetic pathways for most phytochemicals are not fully elucidated. Heterologous production of phytochemicals in plant, bacterial, and yeast hosts has been pursued as a potential approach to address sourcing issues associated with many valuable phytochemicals, and more recently has been utilized as a tool to aid in the elucidation of plant biosynthetic pathways. Due to the structural complexity of certain phytochemicals and the associated biosynthetic pathways, reconstitution of plant pathways in heterologous hosts can encounter numerous challenges. Synthetic biology approaches have been developed to address these challenges in areas such as precise control over heterologous gene expression, improving functional expression of heterologous enzymes, and modifying central metabolism to increase the supply of precursor compounds into the pathway. These strategies have been applied to advance plant pathway reconstitution and phytochemical production in a wide variety of heterologous hosts. Here, we review synthetic biology strategies that have been recently applied to advance complex phytochemical production in heterologous hosts.

Planning and Design of Water Resources Systems Under Climate Change and Variability

Regional and local water supplies and demands are impacted by global and national systems: climate, economics, population and energy as well as policies: development, energy, and environmental. These drivers can result in complex interactions that require deeper understanding in order to provide actionable information for water planners and stakeholders to develop strategic plans in the face of a changing and growing world. To add more complexity to this issue is the fact that all these drivers are uncertain and the type of uncertainty is not the same. This talk will address approaches to Water Resource Planning at sub-national water regions, national levels and trans-boundary river basins under a non-stationary hydro-climatic future. Additionally the talk will address the design of specific water resource projects such as reservoirs and hydroplants that are being designed now but will operate far in the future when the hydro-climatology will be very different. Examples will be drawn from recent work in Africa, Eastern Europe and Central Asia, and North America and some insights and outstanding questions will be presented.

Infertility counseling is a specialized field that will continue to grow in coming years as the impact of infertility and its treatment is documented more in terms of emotional, physical, social and life consequences. We report here on more recent developments in halakha (Jewish law and ethics) that are of importance to Orthodox Jewish infertile couple considering donor gametes or surrogacy. Counselors should anticipate issues that may arise in the future and assist couples in their efforts to address them. Good medical practice values the importance of understanding the patient's individual concerns and values, including the complex psychological, sociological and cultural context in which they experience their infertility. Good counseling anticipates and addresses future problems about which patients might not currently be aware, and requires up-to-date authoritative information.

Nutritional issues for older adults: addressing degenerative ageing with long-term studies.

The ageing process is influenced by a variety of factors, including extrinsic, malleable lifestyle variables. The present paper deals with the epidemiological evidence for the role of dietary patterns and key nutritional concerns in relation to survival and ageing-related disorders that present themselves in later life. Healthful dietary patterns appear to be most relevant in old age. Specific nutritional concerns are related to vitamin D, vitamin B12 and protein malnutrition. An important challenge to further expand the knowledge base is currently addressed by the NuAge project, acknowledging the complexity of the ageing process and integrating different dimensions of research into human healthy ageing. In the meantime, reversing poor adherence to existing guidelines for a healthy diet remains a first challenge in public health nutritional practices.

Addressing the health needs of the homeless.

Several authors have alluded to the complex health needs of the homeless population in the UK. The correlation between homelessness and a wide range of health problems has been explored in the literature. This paper presents a literature review exploring the biological, psychosocial and sexual health needs of single homeless people. The relationship between health and homelessness is analysed in relation to theories of health inequalities, which suggest that being homeless may be both a cause and a consequence of ill health. The contemporary nurse can play a vital role in helping to overcome the barriers that homeless people face when accessing health services. This paper explores the skills and approaches that nurses in a wide variety of settings can employ in addressing the health issues of homeless clients.

Remembering Complex Objects in Visual Working Memory: Do Capacity Limits Restrict Objects or Features?

Visual working memory stores stimuli from our environment as representations that can be accessed by high-level control processes. This study addresses a longstanding debate in the literature about whether storage limits in visual working memory include a limit to the complexity of discrete items. We examined the issue with a number of change-detection experiments that used complex stimuli which possessed multiple features per stimulus item. We manipulated the number of relevant features of the stimulus objects in order to vary feature load. In all of our experiments, we found that increased feature load led to a reduction in change-detection accuracy. However, we found that feature load alone could not account for the results, but that a consideration of the number of relevant objects was also required. This study supports capacity limits for both feature and object storage in visual working memory. PMID:25089739
