Reclaiming wetlands following open pit mining for industrial oil sand extraction is challenging due to the physical and chemical conditions of the post-mined landscape. The aim of our study was to examine and compare the influence of oil sands process water (OSPW) and material (fine fluid tails or FFT) on the plant community composition of created wetlands. Compared to created-unamended and natural wetlands, the created wetlands amended with OSPW and/or FFT (created-tailings wetlands) had significantly higher water salinity, conductivity, dissolved oxygen concentration and lower oxidative-reductive potential. Water chemistry parameters of created-unamended did not differ significantly from those of natural wetlands. The sediment of created wetlands had significantly less moisture, total nitrogen, and organic content than the natural wetlands. The application of OSPW/FFT in created wetlands will likely lead to initial vegetation composition atypical of natural regional wetlands. For the objective of reclaiming vegetation composition to the status of natural regional wetlands, unamended wetlands were the best reclamation option, based on the physical and chemical parameters measured. Despite being the favored reclamation option, created-unamended wetlands' physical and chemical characteristics remain atypical of natural wetlands. Most significantly, the basin morphometry of created wetlands was significantly different from that of naturally-formed wetlands in the region, and this appears to partly explain difference in vegetation composition. We also demonstrate that species richness alone is not a useful measure in wetland monitoring. Instead, plant community composition is a better indicator of wetland conditions.

Reichert, William “Monty”; Ratner, Buddy D.; Anderson, James; Coury, Art; Hoffman, Allan S.; Laurencin, Cato T.; Tirrell, David

2014-01-01

In 2009, the National Academy for Engineering issued the Grand Challenges for Engineering in the 21st Century comprised of 14 technical challenges that must be addressed to build a healthy, profitable, sustainable, and secure global community (http://www.engineeringchallenges.org). Although crucial, none of the NEA Grand Challenges adequately addressed the challenges that face the biomaterials community. In response to the NAE Grand Challenges, Monty Reichert of Duke University organized a panel entitled Grand Challenges in Biomaterials at the at the 2010 Society for Biomaterials Annual Meeting in Seattle. Six members of the National Academies—Buddy Ratner, James Anderson, Allan Hoffman, Art Coury, Cato Laurencin, and David Tirrell—were asked to propose a grand challenge to the audience that, if met, would significantly impact the future of biomaterials and medical devices. Successfully meeting these challenges will speed the 60-plus year transition from commodity, off-the-shelf biomaterials to bioengineered chemistries, and biomaterial devices that will significantly advance our ability to address patient needs and also to create new market opportunities.

2018-06-15

The greatest challenge facing medicine today involves the so-called non-communicable diseases (NCDs). This is true regardless of whether one's location is considered high-income, middle-income, or low-income. Basic research at all "OMICs" system levels will be significant in uncovering causal links that create NCD vulnerabilities in mind, brain, body, and society. Therefore, meeting this 21st century challenge by improving NCD management and prevention around the world will rely on advancement in this type of basic research.

What Are the Professional, Political, and Ethical Challenges of Co-Creating Health Care Systems?

PubMed

Singh, Guddi; Owens, John; Cribb, Alan

2017-11-01

Co-creation is seen by many as a means of meeting the multiple challenges facing contemporary health care systems by involving institutions, professionals, patients, and stakeholders in new roles, relationships, and collaborative practices. While co-creation has the potential to positively transform health care systems, it generates a number of political and ethical challenges that should not be overlooked. We suggest that those involved in envisioning and implementing co-creation initiatives pay close attention to significant questions of equity, power, and justice and to the fundamental challenge of securing a common vision of the aims of and agendas for health care systems. While such initiatives present significant opportunities for improvement, they need to be viewed in light of their accompanying professional, political, and ethical challenges. © 2017 American Medical Association.

Conflict and the subsequent displacement of populations creates unique challenges in the delivery of quality health care to the affected population. Equitable access to quality care demands a multi-pronged strategy with a growing need, and role, for technological innovation to address these challenges. While there have been significant contributions towards alleviating the burden of conflict via data informatics and analytics, communication technology, and geographic information systems, little has been done within biomedical engineering. This article elaborates on the causes for gaps in biomedical innovation for refugee populations affected by conflict, tackles preconceived notions, takes stock of recent developments in promising technologies to address these challenges, and identifies tangible action items to create a stronger and sustainable pipeline for biomedical technological innovation to improve the health and well-being of an increasing group of vulnerable people around the world.

Opportunities and Challenges for Practical Training in Public Health: Insights from Practicum Coordinators in Ontario.

2018-06-12

Dietetic educators and practicum coordinators (PC) play critical roles in preparing students for practice. Dietitians have made significant progress in the development of educational curricula, competencies, and other resources to support knowledge and skill attainment in public health. There are identified gaps in the literature concerning practical training in sustainable food systems and public health, creating barriers in knowledge exchange and improvements in practicum programs in Canada. This paper discusses the potential opportunities and challenges associated with the number of placements for practical training in public health based on interviews with PCs in Ontario. The findings are limited to the perspectives of 7 PCs with experience in practical training and are a starting point for ongoing evaluation. Identified opportunities within traditional and "emerging settings" for practical training in public health included: the uniqueness of the experience, the potential for students to learn outside their comfort zones, and greater possibilities for dietitians in new roles and settings. Challenges included the need for significant PC engagement with nondietetic preceptors and a narrow view of dietetic practice among some dietitians. Interprofessional teams, emerging settings, and flexible learning approaches may create and support practical training opportunities in food systems and public health going forward.

Suyemoto, Karen L; Fox Tree, Claudia A

2006-06-01

Although challenges of anti-racist work are most commonly framed in relation to White people and People of Color, there are significant challenges involved in creating allies across minority racial groups. This article describes our experiences within a community organization aimed at training anti-racist culturally sensitive K-12 educators. As Asian American and Native American facilitators within a group of facilitators of color who were predominantly Black, we describe our experiences of relative marginalization and our (mostly failed) attempts to create change within the organization to be more inclusive of the perspectives, experiences, and needs of non-Black people/students of color. We contextualize these experienced conflicts in relation to race hierarchies, the "divide and conquer strategy" and the maintenance of White privilege. We offer reflections for how racial minorities engaged in anti-racist education could be better allies and how organizations might better foster environments that contribute to the creation of these alliances.

The importance of creating healthier work environments by providing healthy foods and beverages in worksite cafeterias, in on-site vending machines, and at meetings and conferences is drawing increasing attention. Large employers, federal and state governments, and hospital systems are significant purchasers and providers of food and beverages. The American Heart Association, federal government, and other organizations have created procurement standards to guide healthy purchasing by these entities. There is a need to review how procurement standards are currently implemented, to identify important minimum criteria for evaluating health and purchasing outcomes, and to recognize significant barriers and challenges to implementation, along with success stories. The purpose of this policy paper is to describe the role of food-and-beverage environment and procurement policy standards in creating healthier worksite environments; to review recently created national model standards; to identify elements across the standards that are important to consider for incorporation into policies; and to delineate issues to address as standards are implemented across the country. © 2014 International Life Sciences Institute.

Towards addressing transient learning challenges in undergraduate physics: an example from electrostatics

NASA Astrophysics Data System (ADS)

Fredlund, T.; Linder, C.; Airey, J.

2015-09-01

In this article we characterize transient learning challenges as learning challenges that arise out of teaching situations rather than conflicts with prior knowledge. We propose that these learning challenges can be identified by paying careful attention to the representations that students produce. Once a transient learning challenge has been identified, teachers can create interventions to address it. By illustration, we argue that an appropriate way to design such interventions is to create variation around the disciplinary-relevant aspects associated with the transient learning challenge.

Capasso, Cristian; Garofalo, Mariangela; Hirvinen, Mari; Cerullo, Vincenzo

2014-02-17

A long time has passed since the first clinical trial with adenoviral (Ad) vectors. Despite being very promising, Ad vectors soon revealed their limitations in human clinical trials. The pre-existing immunity, the marked liver tropism and the high toxicity of first generation Ad (FG-Ad) vectors have been the main challenges for the development of new approaches. Significant effort toward the development of genetically and chemically modified adenoviral vectors has enabled researchers to create more sophisticated vectors for gene therapy, with an improved safety profile and a higher transduction ability of different tissues. In this review, we will describe the latest findings in the high-speed, evolving field of genetic and chemical modifications of adenoviral vectors, a field in which different disciplines, such as biomaterial research, virology and immunology, co-operate synergistically to create better gene therapy tools for modern challenges.

Wearable sensors have recently seen a large increase in both research and commercialization. However, success in wearable sensors has been a mix of both progress and setbacks. Most of commercial progress has been in smart adaptation of existing mechanical, electrical and optical methods of measuring the body. This adaptation has involved innovations in how to miniaturize sensing technologies, how to make them conformal and flexible, and in the development of companion software that increases the value of the measured data. However, chemical sensing modalities have experienced greater challenges in commercial adoption, especially for non-invasive chemical sensors. There have also been significant challenges in making significant fundamental improvements to existing mechanical, electrical, and optical sensing modalities, especially in improving their specificity of detection. Many of these challenges can be understood by appreciating the body's surface (skin) as more of an information barrier than as an information source. With a deeper understanding of the fundamental challenges faced for wearable sensors and of the state-of-the-art for wearable sensor technology, the roadmap becomes clearer for creating the next generation of innovations and breakthroughs.

A brief review of extrusion-based tissue scaffold bio-printing.

Ning, Liqun; Chen, Xiongbiao

2017-08-01

Extrusion-based bio-printing has great potential as a technique for manipulating biomaterials and living cells to create three-dimensional (3D) scaffolds for damaged tissue repair and function restoration. Over the last two decades, advances in both engineering techniques and life sciences have evolved extrusion-based bio-printing from a simple technique to one able to create diverse tissue scaffolds from a wide range of biomaterials and cell types. However, the complexities associated with synthesis of materials for bio-printing and manipulation of multiple materials and cells in bio-printing pose many challenges for scaffold fabrication. This paper presents an overview of extrusion-based bio-printing for scaffold fabrication, focusing on the prior-printing considerations (such as scaffold design and materials/cell synthesis), working principles, comparison to other techniques, and to-date achievements. This paper also briefly reviews the recent development of strategies with regard to hydrogel synthesis, multi-materials/cells manipulation, and process-induced cell damage in extrusion-based bio-printing. The key issue and challenges for extrusion-based bio-printing are also identified and discussed along with recommendations for future, aimed at developing novel biomaterials and bio-printing systems, creating patterned vascular networks within scaffolds, and preserving the cell viability and functions in scaffold bio-printing. The address of these challenges will significantly enhance the capability of extrusion-based bio-printing. Copyright © 2017 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

Virtual reality in surgery and, more specifically, in surgical training, faces a number of challenges in the future. These challenges are building realistic models of the human body, creating interface tools to view, hear, touch, feel, and manipulate these human body models, and integrating virtual reality systems into medical education and treatment. A final system would encompass simulators specifically for surgery, performance machines, telemedicine, and telesurgery. Each of these areas will need significant improvement for virtual reality to impact medicine successfully in the next century. This article gives an overview of, and the challenges faced by, current systems in the fast-changing field of virtual reality technology, and provides a set of specific milestones for a truly realistic virtual human body.

The Sustainable Development of Space: Astro-environmental and dynamical considerations

NASA Astrophysics Data System (ADS)

Boley, Aaron; Byers, Michael; Russell, Sara

2018-04-01

The sustainable development of space is a global (and exo-global) challenge that is not limited by borders or research disciplines. Sustainable development is "development that meets the needs of the present without compromising the ability of future generations to meet their own needs". While the development of space brings new economic and scientific possibilities, it also carries significant political, legal, and technical uncertainties. For example, the rapidly increasing accessibility of space is motivating states to unilaterally adopt legislation for the new era of space use, which may have significant unintended consequences, such as increased risks to space assets, disputes among state as well as non-state actors, and changes to unique astro-environments. Any policy or legal position must be informed by the dynamical and astrophysical realities of space use, creating complex and interwoven challenges. Here, we explore several of these potential challenges related to astro-environmentalism, space minining operations, and the associated dynamics.

Continuous quality improvement programs provide new opportunities to drive value innovation initiatives in hospital-based radiology practices.

PubMed

Steele, Joseph R; Schomer, Don F

2009-07-01

Imaging services constitute a huge portion of the of the total dollar investment within the health care enterprise. Accordingly, this generates competition among medical specialties organized along service lines for their pieces of the pie and increased scrutiny from third-party payers and government regulators. These market and political forces create challenge and opportunity for a hospital-based radiology practice. Clearly, change that creates or builds greater value for patients also creates sustainable competitive advantage for a radiology practice. The somewhat amorphous concept of quality constitutes a significant value driver for innovation in this scenario. Quality initiatives and programs seek to define and manage this amorphous concept and provide tools for a radiology practice to create or build more value. Leadership and the early adoption of these inevitable programs by a radiology practice strengthens relationships with hospital partners and slows the attrition of imaging service lines to competitors.

Necessary but not sufficient? Engaging young people in the development of an avatar-based online intervention designed to provide psychosocial support to young people affected by their own or a family member's cancer diagnosis.

This study discusses the challenges and successes of engaging young people in a project aimed at developing an online counselling intervention for young people affected by cancer. For younger people with a diagnosis of cancer or who are caring for someone with cancer, the psychosocial consequences can create significant challenges for their social and educational development. Whilst young people have been shown to be reluctant to make use of traditional face-to-face counselling, research is beginning to suggest that effective therapeutic relationships can be formed with young people online. The first phase of the study involved working with a 'Young Persons' Panel' of healthy school pupils and university students to develop and pilot an online counselling intervention and study materials in preparation for a pilot evaluation of the intervention. An avatar-based virtual reality counselling world was created where young people can create their own avatar and receive counselling over the Internet from a qualified counsellor via an avatar in a virtual reality world. The process of engaging young people in the C:EVOLVE project enabled a unique intervention to be developed and demonstrated positive developmental opportunities. However, despite the rigorous approach to the development of the intervention, initial attempts within the pilot evaluation phase of the study showed difficulties recruiting to the study, and this phase of the study has currently ceased whilst further exploratory work takes place. This study has demonstrated the complexities of intervention development and evaluation research targeted at young people and the challenges created when attempting to bring clinical practice and research evaluation together. © 2016 The Authors.

We discuss the inter-relationship between various concepts of complexity by introducing a complexity 'triangle' featuring objective complexity, subjective complexity and social complexity. Their connections are explored using visual and musical compositions of art. As examples, we quantify the complexity embedded within the paintings of the Jackson Pollock and the musical works of Johann Sebastian Bach. We discuss the challenges inherent in comparisons of the spatial patterns created by Pollock and the sonic patterns created by Bach, including the differing roles that time plays in these investigations. Our results draw attention to some common intriguing characteristics suggesting 'universality' and conjecturing that the fractal nature of art might have an intrinsic value of more general significance.

In healthcare, big data tools and technologies have the potential to create significant value by improving outcomes while lowering costs for each individual patient. Diagnostic images, genetic test results and biometric information are increasingly generated and stored in electronic health records presenting us with challenges in data that is by nature high volume, variety and velocity, thereby necessitating novel ways to store, manage and process big data. This presents an urgent need to develop new, scalable and expandable big data infrastructure and analytical methods that can enable healthcare providers access knowledge for the individual patient, yielding better decisions and outcomes. In this paper, we briefly discuss the nature of big data and the role of semantic web and data analysis for generating "smart data" which offer actionable information that supports better decision for personalized medicine. In our view, the biggest challenge is to create a system that makes big data robust and smart for healthcare providers and patients that can lead to more effective clinical decision-making, improved health outcomes, and ultimately, managing the healthcare costs. We highlight some of the challenges in using big data and propose the need for a semantic data-driven environment to address them. We illustrate our vision with practical use cases, and discuss a path for empowering personalized medicine using big data and semantic web technology.

Incorporating national priorities into the curriculum.

There are many aspects of care that need an overhaul to function safely, efficiently, and effectively. There needs to be a new culture in health care that focuses on safety and quality, and it will take many shareholders working together to make this possible. The National Priorities Partnership is a group of 28 national organizations from across the health care spectrum collaborating to change the health care delivery system. The Partners acknowledged four challenges individuals face in the current U.S. system: harm, disparity, disease burden, and waste. To meet these challenges and improve performance, the Partners identified six priorities: patient and family engagement, population health, safety, care coordination, palliative and end-of-life care, and overuse (National Priorities Partnership). It is hopeful that when put into practice, these essentials will have a significant impact on improving health care. It comes down to creating a culture of safety and quality. This culture should start during entry-level education for health care providers, such as nursing schools. The priorities and goals provide a framework that can be incorporated into the curriculum so future nurses are aware of the issues and challenges in health care today. Each challenge needs evidence-based strategies for achieving the desired results. It is time to create a culture of safety and quality in health care. Copyright © 2012 Elsevier Inc.

Maternal and child health indicators are generally poor in Nigeria with the northern part of the country having the worst indicators than the southern part. Efforts to address maternal and health challenges in Nigeria include, among others, improvement in health and management information systems. We report on the experience of mobile phone technology in supporting the activities of a health and demographic surveillance system in northern Nigeria. Our experience calls for the need for the Nigerian Government, the mobile network companies, and the international community at large to consolidate their efforts in addressing the mobile network coverage and power supply challenges in order to create an enabling environment for socio-economic development particularly in rural and disadvantaged areas. Unless power and mobile network challenges are addressed, health interventions that rely on mobile phone technology will not have a significant impact in improving maternal and child health.

Rheumatic heart disease (RHD) has long receded as a significant threat to public health in high-income countries. In low-resource settings, however, the specter of RHD remains unabated, as exemplified by recent data from the Global Burden of Diseases Study. There are many complex reasons for this ongoing global disparity, including inadequate data on disease burden, challenges in effective advocacy, ongoing poverty and inequality, and weak health systems, most of which predominantly affect developing nations. In this review, we discuss how each of these acts as a core challenge in RHD prevention and control. We then examine key lessons learnt from successful control programs in the past and highlight resources that have been developed to help create strong national RHD control programs.

Hauton, Chris

2017-07-01

The sustainable intensification of crustacean aquaculture, which is dominated by the farming of penaeid shrimp species, continues to be beset by viral disease outbreaks. Despite this, reports exist of differential susceptibility to viral infection between different shrimp species and populations, and between shrimp and other decapod crustaceans. These reports have, in part, provided the motivation to identify key mechanisms of antiviral resistance, or refractivity, in commercially-important species. Within the last decade these studies have created significant advances in our understanding of host virus interactions in decapod models. However, at the same time, the complexity of host virus interactions has presented significant challenges for interpretation of anti-viral immune responses. In this short review, recent progress in our understanding of the complexity of host virus interactions are considered, and challenges to the unequivocal identification of anti-viral immunity are highlighted. Special consideration is given to the advances in understanding being created by the use of RNA interference approaches. Based on the 'state of the art', it is concluded that the identification of effective intervention strategies for application at farm scale currently presents an unrealistic target for the aquaculture industry. Future technical developments necessary to support continued progress are also considered. Copyright © 2017 Elsevier Inc. All rights reserved.

There is a pressing need for high-quality, effective means of designing, developing, presenting, implementing, evaluating, and maintaining all types of clinical decision support capabilities for clinicians, patients and consumers. Using an iterative, consensus-building process we identified a rank-ordered list of the top 10 grand challenges in clinical decision support. This list was created to educate and inspire researchers, developers, funders, and policy-makers. The list of challenges in order of importance that they be solved if patients and organizations are to begin realizing the fullest benefits possible of these systems consists of: Improve the human-computer interface; Disseminate best practices in CDS design, development, and implementation; Summarize patient-level information; Prioritize and filter recommendations to the user; Create an architecture for sharing executable CDS modules and services; Combine recommendations for patients with co-morbidities; Prioritize CDS content development and implementation; Create internet-accessible clinical decision support repositories; Use freetext information to drive clinical decision support; Mine large clinical databases to create new CDS. Identification of solutions to these challenges is critical if clinical decision support is to achieve its potential and improve the quality, safety and efficiency of healthcare. PMID:18029232

Jadad, Alejandro R

2016-11-01

Imagine a world in which every human being is healthy until the last breath. Thanks to the fast penetration of digital technologies in every region of the planet, this seemingly utopian scenario is not only feasible but also potentially viable. Now that digital technologies have provided almost full interconnectivity among all humans, they should be used to meet key challenges to ensure that health is created and that it spreads to reach every person on earth. The objective of this article is to describe and trigger a serious discussion of such challenges, which include: adopting a new concept of health; positioning self-rated health as the main outcome of the system; creating a health-oriented model to guide service provision; facilitating the identification, scaling up, and sustaining of innovations that can create and spread health; promoting a culture of health promotion; and encouraging the emergence of Precision Health. Once these challenges are met, and health becomes pandemic, public health would have fulfilled its vision, a healthy life for all, at last.

Postmortem Brain: An Underutilized Substrate for Studying Severe Mental Illness

PubMed Central

McCullumsmith, Robert E; Hammond, John H; Shan, Dan; Meador-Woodruff, James H

2014-01-01

We propose that postmortem tissue is an underutilized substrate that may be used to translate genetic and/or preclinical studies, particularly for neuropsychiatric illnesses with complex etiologies. Postmortem brain tissues from subjects with schizophrenia have been extensively studied, and thus serve as a useful vehicle for illustrating the challenges associated with this biological substrate. Schizophrenia is likely caused by a combination of genetic risk and environmental factors that combine to create a disease phenotype that is typically not apparent until late adolescence. The complexity of this illness creates challenges for hypothesis testing aimed at understanding the pathophysiology of the illness, as postmortem brain tissues collected from individuals with schizophrenia reflect neuroplastic changes from a lifetime of severe mental illness, as well as treatment with antipsychotic medications. While there are significant challenges with studying postmortem brain, such as the postmortem interval, it confers a translational element that is difficult to recapitulate in animal models. On the other hand, data derived from animal models typically provide specific mechanistic and behavioral measures that cannot be generated using human subjects. Convergence of these two approaches has led to important insights for understanding molecular deficits and their causes in this illness. In this review, we discuss the problem of schizophrenia, review the common challenges related to postmortem studies, discuss the application of biochemical approaches to this substrate, and present examples of postmortem schizophrenia studies that illustrate the role of the postmortem approach for generating important new leads for understanding the pathophysiology of severe mental illness.

Gender-based violence and HIV are highly prevalent in the harsh environment of informal settlements and reducing violence here is very challenging. The group intervention Stepping Stones has been shown to reduce men's perpetration of violence in more rural areas, but violence experienced by women in the study was not affected. Economic empowerment interventions with gender training can protect older women from violence, but microloan interventions have proved challenging with young women. We investigated whether combining a broad economic empowerment intervention and Stepping Stones could impact on violence among young men and women. The intervention, Creating Futures, was developed as a new generation of economic empowerment intervention, which enabled livelihood strengthening though helping participants find work or set up a business, and did not give cash or make loans. We piloted Stepping Stones with Creating Futures in two informal settlements of Durban with 232 out of school youth, mostly aged 18-30 and evaluated with a shortened interrupted time series of two baseline surveys and at 28 and 58 weeks post-baseline. 94/110 men and 111/122 women completed the last assessment, 85.5% and 90.2% respectively of those enrolled. To determine trend, we built random effects regression models with each individual as the cluster for each variable, and measured the slope of the line across the time points. Men's mean earnings in the past month increased by 247% from R411 (~$40) to R1015 (~$102, and women's by 278% R 174 (~$17) to R 484 (about $48) (trend test, p < 0.0001). There was a significant reduction in women's experience of the combined measure of physical and/or sexual IPV in the prior three months from 30.3% to 18.9% (p = 0.037). This was not seen for men. However both men and women scored significantly better on gender attitudes and men significantly reduced their controlling practices in their relationship. The prevalence of moderate or severe depression symptomatology among men and suicidal thoughts decreased significantly (p < 0.0001 and p = 0.01). These findings are very positive for an exploratory study and indicate that the Creating Futures/Stepping Stones intervention has potential for impact in these difficult areas with young men and women. Further evaluation is needed.

Structural technology challenges for evolutionary growth of Space Station Freedom

NASA Technical Reports Server (NTRS)

Doiron, Harold H.

1990-01-01

A proposed evolutionary growth scenario for Space Station Freedom was defined recently by a NASA task force created to study requirements for a Human Exploration Initiative. The study was an initial response to President Bush's July 20, 1989 proposal to begin a long range program of human exploration of space including a permanently manned lunar base and a manned mission to Mars. This growth scenario evolves Freedom into a critical transportation node to support lunar and Mars missions. The growth scenario begins with the Assembly Complete configuration and adds structure, power, and facilities to support a Lunar Transfer Vehicle (LTV) verification flight. Evolutionary growth continues to support expendable, then reusable LTV operations, and finally, LTV and Mars Transfer Vehicle (MTV) operations. The significant structural growth and additional operations creating new loading conditions will present new technological and structural design challenges in addition to the considerable technology requirements of the baseline Space Station Freedom program. Several structural design and technology issues of the baseline program are reviewed and related technology development required by the growth scenario is identified.

Challenging homophobia and heterosexism through storytelling and critical dialogue among Hong Kong Chinese immigrant parents in Toronto.

Wong, Josephine Pui-Hing; Poon, Maurice Kwong-Lai

2013-01-01

Homophobia and heterosexism are ubiquitous in Canadian society. They contribute to significant health and mental health disparities for lesbian, gay and bisexual youth and their families. Anti-homophobia efforts tend to focus on students and teachers at school. While these efforts are important, they do not reach parents, who play an important role in shaping young people's attitudes towards gender and sexuality. To eliminate bullying and victimisation associated with homophobia at school and in the community, concerted efforts are urgently needed to mobilise parents to become champions against homophobia and heterosexism. In this paper, we report on our use of storytelling and critical dialogue to engage a group of Hong Kong Chinese immigrant parents in Toronto to interrogate their values and assumptions about homosexuality. In particular, we illustrate how we use storytelling to create a liminal space whereby the narrators and listeners collaborate to create counter-discourses that challenge social domination and exclusion. We then discuss the implications of using a critical dialogical approach to integrate anti-homophobia efforts in community parenting programmes.

In 1998 the tobacco industry was released of claims that provided monetary relief for states. A significant expansion of tobacco control activity in many states created a need to develop local capacity. Technical assistance and training for new and experienced staff became a significant challenge for tobacco control leadership. In Colorado, this challenge was addressed in part through the development of a technical assistance and training Web site designed for local tobacco control staff and coalition members. Researchers, technical Web site development specialists, state health agency, and state tobacco control coalition staff collaborated to develop, promote, and test the efficacy of this Web site. The work group embodied a range of skills including tobacco control, Web site technical development, marketing, training, and project management. Persistent marketing, updating of Web site content, and institutionalizing it as a principal source of information and training were key to use by community coalition members.

The development of advanced engines has significant potential advantages in reduced aftertreatment costs for air pollutant emission control, and just as importantly for efficiency improvements and associated greenhouse gas emission reductions. There are significant opportunities to leverage fuel properties to create more optimal engine designs for both advanced spark-ignition and compression-ignition combustion strategies. The fact that biofuel blendstocks offer a potentially low-carbon approach to fuel production, leads to the idea of optimizing the entire fuel production-utilization value chain as a system from the standpoint of life cycle greenhouse gas emissions. This is a difficult challenge that has yet to bemore » realized. This presentation will discuss the relationship between chemical structure and critical fuel properties for more efficient combustion, survey the properties of a range of biofuels that may be produced in the future, and describe the ongoing challenges of fuel-engine co-optimization.« less

Multi-agency coordination represents a significant challenge in emergency management. The need for liaison officers working in strategic level emergency operations centres to play organizational boundary spanning roles within multi-agency coordination arrangements that are enacted in complex and dynamic emergency response scenarios creates significant research and practical challenges. The aim of the paper is to address a gap in the literature regarding the concept of multi-agency coordination from a human-environment interaction perspective. We present a theoretical framework for facilitating multi-agency coordination in emergency management that is grounded in human factors and ergonomics using the methodology of core-task analysis. As a result we believe the framework will enable liaison officers to cope more efficiently within the work domain. In addition, we provide suggestions for extending the theory of core-task analysis to an alternate high reliability environment. Copyright © 2014 Elsevier Ltd and The Ergonomics Society.

The task of creating and maintaining a front end to a large institutional entity-attribute-value (EAV) database can be cumbersome when using traditional client-server technology. Switching to Web technology as a delivery vehicle solves some of these problems but introduces others. In particular, Web development environments tend to be primitive, and many features that client-server developers take for granted are missing. WebEAV is a generic framework for Web development that is intended to streamline the process of Web application development for databases having a significant EAV component. It also addresses some challenging user interface issues that arise when any complex system is created. The authors describe the architecture of WebEAV and provide an overview of its features with suitable examples. PMID:10887163

System engineering and science projects: lessons from MeerKAT

2016-08-01

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

2016-11-01

Obesity is a common disorder with complex causes. The epidemic has spurred significant advances in the understanding of nutritional approaches to treating obesity. Although the primary challenge is to introduce a dietary intake that creates an energy deficit, clinicians should also consider targeted risk factor modification with manipulation of the nutrient profile of the weight-reducing diet. These strategies produce significant weight loss and improvements in cardiometabolic risk factors. Future research is needed to better understand how to personalize nutrient prescriptions further to promote optimal risk modification and maintenance of long-term energy balance in the weight-reduced state.

Since An Overview of the Trilinos Project [ACM Trans. Math. Softw. 31(3) (2005), 397–423] was published in 2005, Trilinos has grown significantly. It now supports the development of a broad collection of libraries for scalable computational science and engineering applications, and a full-featured software infrastructure for rigorous lean/agile software engineering. This growth has created significant opportunities and challenges. This paper focuses on some of the most notable changes to the Trilinos project in the last few years. At the time of the writing of this article, the current release version of Trilinos was 10.12.2.

In recent years, scientists have developed various biomaterials to remineralize human teeth to treat dentine hypersensitivity. Poly(amido amine) (PAMAM) dendrimers have become a research focus in this field. It has been demonstrated that PAMAM is able to create precipitates both on the surface of and within the dentinal tubules, however, there is little information about its effect on reducing dentine permeability in vitro. This study aimed to evaluate the in vitro effectiveness and stability of the fourth generation amine-terminated PAMAM on dentinal tubule occlusion, especially on dentine permeability. Sodium fluoride (NaF), which has been widely used as a desensitizing agent, is regarded as positive control. Demineralized sensitive dentine samples were coated with PAMAM or sodium fluoride solutions and soaked in artificial saliva (AS) at 37 °C for different periods. Four weeks later, samples in each group were then equally split into two subgroups for testing using a brushing challenge and an acid challenge. Dentine permeability of each specimen was measured before and after each challenge using a fluid filtration system. Dentine morphology and surface deposits were characterized by scanning electron microscope (SEM) and analyzed with Image-Pro Plus software. Data were evaluated through multifactorial ANOVA with repeated measures and pair-wise comparisons at a level of 5%. The results showed that PAMAM and NaF significantly reduced dentine permeability to 25.1% and 20.7%. Both of them created precipitates on dentine surfaces after AS immersion for 28 days. PAMAM-induced biomineralization not only on dentine surfaces, but also deeper in dentinal tubules, significantly reduced dentine permeability. Moreover, PAMAM-induced biomineralization elicited excellent stable occlusion effects after acid challenge. In conclusion, PAMAM demonstrated a strong ability to resist acid and showed great potential to be used in the treatment of dentine hypersensitivity in future. PMID:28772744

Cortelyou-Ward, Kendall; Ramirez, Bernardo; Rotarius, Timothy

2011-01-01

Most clinical laboratories in the nation report severe difficulties in recruitment and retention of most types of personnel. Other important factors impacting this problem include work complexities, increased automation, and a graying workforce. As a further challenge, institutional needs for clinical laboratory personnel are expected to grow significantly in the next decade. This article examines the current situation of the clinical laboratory workforce. It analyzes the different types of personnel; the managerial, supervision, and line positions that are key for different types of laboratories; the job outlook and recent projections for different types of staff; and the current issues, trends, and challenges of the laboratory workforce. Laboratory managers need to take action with strategies suggested for overcoming these challenges. Most importantly, they need to become transformational leaders by developing effective staffing models, fostering healthy and productive work environments, and creating value with a strategic management culture and implementation of knowledge management.

2017-03-20

The use of social network theory and analysis methods as applied to public health has expanded greatly in the past decade, yielding a significant academic literature that spans almost every conceivable health issue. This review identifies several important theoretical challenges that confront the field but also provides opportunities for new research. These challenges include (a) measuring network influences, (b) identifying appropriate influence mechanisms, (c) the impact of social media and computerized communications, (d) the role of networks in evaluating public health interventions, and (e) ethics. Next steps for the field are outlined and the need for funding is emphasized. Recently developed network analysis techniques, technological innovations in communication, and changes in theoretical perspectives to include a focus on social and environmental behavioral influences have created opportunities for new theory and ever broader application of social networks to public health topics.

The alkaline tide and ammonia excretion after voluntary feeding in freshwater rainbow trout.

PubMed

Bucking, Carol; Wood, Chris M

2008-08-01

We investigated the potential acid-base and nitrogenous waste excretion challenges created by voluntary feeding in freshwater rainbow trout, with particular focus on the possible occurrence of an alkaline tide (a metabolic alkalosis created by gastric HCl secretion during digestion). Plasma metabolites (glucose, urea and ammonia) were measured at various time points before and after voluntary feeding to satiation (approximately 5% body mass meal of dry commercial pellets), as was the net flux of ammonia and titratable alkalinity to the water from unfed and fed fish. Arterial blood, sampled by indwelling catheter, was examined for post-prandial effects on pH, plasma bicarbonate and plasma CO2 tension. There was no significant change in plasma glucose or urea concentrations following feeding, whereas plasma ammonia transiently increased, peaking at threefold above resting values at 12 h after the meal and remaining elevated for 24 h. The increased plasma ammonia was correlated with an increase in net ammonia excretion to the water, with fed fish significantly elevating their net ammonia excretion two- to threefold between 12 and 48 h post feeding. These parameters did not change in unfed control fish. Fed fish likewise increased the net titratable base flux to the water by approximately threefold, which resulted in a transition from a small net acid flux seen in unfed fish to a large net base flux in fed fish. Over 48 h, this resulted in a net excretion of 13 867 micromol kg(-1) more base to the external water than in unfed fish. The arterial blood exhibited a corresponding rise in pH (between 6 and 12 h) and plasma bicarbonate (between 3 and 12 h) following feeding; however, no respiratory compensation was observed, as PaCO2 remained constant. Overall, there was evidence of numerous challenges created by feeding in a freshwater teleost fish, including the occurrence of an alkaline tide, and its compensation by excretion of base to the external water. The possible influence of feeding ecology and environmental salinity on these challenges, as well as discrepancies in the literature, are discussed.

Multi-Case Knowledge-Based IMRT Treatment Planning in Head and Neck Cancer

NASA Astrophysics Data System (ADS)

Grzetic, Shelby Mariah

Head and neck cancer (HNC) IMRT treatment planning is a challenging process that relies heavily on the planner's experience. Previously, we used the single, best match from a library of manually planned cases to semi-automatically generate IMRT plans for a new patient. The current multi-case Knowledge Based Radiation Therapy (MC-KBRT) study utilized different matching cases for each of six individual organs-at-risk (OARs), then combined those six cases to create the new treatment plan. From a database of 103 patient plans created by experienced planners, MC-KBRT plans were created for 40 (17 unilateral and 23 bilateral) HNC "query" patients. For each case, 2D beam's-eye-view images were used to find similar geometric "match" patients separately for each of 6 OARs. Dose distributions for each OAR from the 6 matching cases were combined and then warped to suit the query case's geometry. The dose-volume constraints were used to create the new query treatment plan without the need for human decision-making throughout the IMRT optimization. The optimized MC-KBRT plans were compared against the clinically approved plans and Version 1 (previous KBRT using only one matching case with dose warping) using the dose metrics: mean, median, and maximum (brainstem and cord+5mm) doses. Compared to Version 1, MC-KBRT had no significant reduction of the dose to any of the OARs in either unilateral or bilateral cases. Compared to the manually planned unilateral cases, there was significant reduction of the oral cavity mean/median dose (>2Gy) at the expense of the contralateral parotid. Compared to the manually planned bilateral cases, reduction of dose was significant in the ipsilateral parotid, larynx, and oral cavity (>3Gy mean/median) while maintaining PTV coverage. MC-KBRT planning in head and neck cancer generates IMRT plans with better dose sparing than manually created plans. MC-KBRT using multiple case matches does not show significant dose reduction compared to using a single match case with dose warping.

How Effective Leaders Harness the Future.

PubMed

Souba, Wiley; Souba, Matthew

2018-02-01

Human beings are fundamentally future oriented. Most of our decisions and undertakings are for the sake of a future to which we are committed or obligated. This future orientation is essential to effective leadership in health care, especially during this time of significant reform, when people are at risk of becoming cynical and disengaged. Conventional thinking holds that our effectiveness as leaders is primarily a function of what we have learned in the past-our knowledge, expertise, and experience. In contrast, the emerging model contends that our effectiveness is also a function of how the future (outcome) of our leadership challenges "shows up" for us. If, despite daunting circumstances, we can "see" an aspired future ahead, we are more likely to commit and engage. Our story of the future becomes the "narrative frame" through which we see and tackle leadership challenges today. Because organizations are fundamentally networks of conversations, an organization's ability to create new language practices is tantamount to its ability to evolve. What makes the future compelling is the embodiment of our deepest convictions and ideals in our image of the future. Because health care reform has challenged the medical profession along the entire spectrum of its traditional values and roles, working toward a unifying vision of the future has been difficult. To enroll others in creating a better future, effective leaders must underscore the purpose and importance of their work and motivate them with inspiring stories.

Mentoring and social skills training: ensuring better outcomes for youth in foster care.

PubMed

Williams, Charles A

2011-01-01

Youth in foster care face significant life challenges that make it more likely that they will face negative outcomes (i.e., school failure, homelessness, and incarceration). While the reason(s) for out-of-home placement (i.e., family violence, abuse, neglect and/or abandonment) provide some context for negative outcomes, such negative outcomes need not be a foregone conclusion. In fact, interventions created to serve at-risk youth could ostensibly address the needs of youth in foster care as well, given that they often face similar social, emotional, and other challenges. Specifically, the author posits that supporting foster care youth through the use ofmentoring and social skills training could reduce the negative outcomes far too common for many of these youth.

Female genital cutting affects over 140 million women worldwide. Prevalent in certain countries of Africa and the Middle East, the practice continues among immigrants to industrialized countries. Female genital cutting is a deeply rooted tradition that confers honor on a woman and her family, yet also a traumatic experience that creates significant dermatological, gynecological, obstetric and infectious disease complications. Little is known about postmenopausal health in cut women. The international community views this practice as a human rights violation. In addition to genital health complications, the medical community must confront an understudied concern of what happens as this population ages. These challenges must be addressed to provide optimal care to women affected by female genital cutting.

The cooperation between interventional cardiologists and cardiothoracic surgeons has expanded the spectrum of treatment modalities for patients with congenital heart disease. These hybrid techniques have created new challenges, one of which being the provision of adequate but practical radiation protection. This study evaluates the use of a lightweight radiation protection drape (RADPAD) that may be suitable for shielding during hybrid procedures. To simulate a pediatric patient, an 8.7 liter water-filled tub was placed on an X-ray table and exposed to 10-second cine acquisition runs. Radiation exposure was measured at twelve specified locations around the table using a model with three different levels of radiation protection: no shielding, shielding using a traditional 0.35 mm lead-equivalent apron, and shielding using the 0.25 mm lead-equivalent RADPAD. The traditional lead apron and the RADPAD significantly reduced the amount of radiation dose when compared with no shielding. The standard lead apron provided slightly greater radiation protection than the RADPAD (0.000064 radiation absorbed dose [rad] vs. 0.000091 rad; p = 0.012). The measured rad was significantly higher on the right side of the table, and the measured radiation dose decreased significantly with increasing distance from the table. The RADPAD has been shown to function as an efficient shielding device, even though it does not quite match the protection that can be expected from a standard lead apron. It complies with regulatory radiation protection requirements and its lightweight and sterile use make it particularly useful during hybrid procedures in the operating room.

Electrification of transport offers opportunities to increase energy security, reduce carbon emissions, and improve local air quality. Plug-in electric vehicles (PEVs) are creating new connections between the transportation and electric sectors, and PEV charging will create opportunities and challenges in a system of growing complexity. Here, I use highly resolved models of residential power demand and PEV use to assess the impact of uncoordinated in-home PEV charging on residential power demand. While the increase in aggregate demand might be minimal even for high levels of PEV adoption, uncoordinated PEV charging could significantly change the shape of the aggregate residential demand,more » with impacts for electricity infrastructure, even at low adoption levels. Clustering effects in vehicle adoption at the local level might lead to high PEV concentrations even if overall adoption remains low, significantly increasing peak demand and requiring upgrades to the electricity distribution infrastructure.

The globalization of clinical research is gaining momentum. In particular, emerging countries, such as Brazil, India, Russia and South Africa show a significant increase in clinical trials. This trend is generating various ethical problems, which are examined in the present article. Sometimes, generally accepted ethical rules, such as the evaluation of clinical trials by ethics commissions are not respected and sometimes conflicts are generated which are difficult to resolve. For instance, it is controversial which standard of care researchers and sponsors have to provide in an international study. These conflicts are exacerbated by a fundamental dilemma: more research on diseases prevalent in developing and emerging countries is necessary. At the same time, the protection of study participants in those countries creates particular challenges. In recent years, international commissions and guidelines have achieved significant progress in solving these conflicts; however, the further development has to be analyzed very carefully. Incentives for better research on neglected diseases have to be created. Undesirable developments and abuse have to be prevented by appropriate international ethical standards.

The task of creating and maintaining a front end to a large institutional entity-attribute-value (EAV) database can be cumbersome when using traditional client-server technology. Switching to Web technology as a delivery vehicle solves some of these problems but introduces others. In particular, Web development environments tend to be primitive, and many features that client-server developers take for granted are missing. WebEAV is a generic framework for Web development that is intended to streamline the process of Web application development for databases having a significant EAV component. It also addresses some challenging user interface issues that arise when any complex system is created. The authors describe the architecture of WebEAV and provide an overview of its features with suitable examples.

MO-DE-BRA-04: The CREATE Medical Physics Research Training Network: Training of New Generation Innovators

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

Seuntjens, J; Collins, L; Devic, S

Purpose: Over the past century, physicists have played a major role in transforming scientific discovery into everyday clinical applications. However, with the increasingly stringent requirements to regulate medical physics as a health profession, the role of physicists as scientists and innovators has become at serious risk of erosion. These challenges trigger the need for a new, revolutionized training program at the graduate level that respects scientific rigor, attention for medical physics-relevant developments in basic sciences, innovation and entrepreneurship. Methods: A grant proposal was funded by the Collaborative REsearch and Training Experience program (CREATE) of the Natural Sciences and Engineering Researchmore » Council (NSERC) of Canada. This enabled the creation of the Medical Physics Research Training Network (MPRTN) around two CAMPEP-accredited medical physics programs. Members of the network consist of medical device companies, government (research and regulatory) and academia. The MPRTN/CREATE program proposes a curriculum with three main themes: (1) radiation physics, (2) imaging & image processing and (3) radiation response, outcomes and modeling. Results: The MPRTN was created mid 2013 (mprtn.com) and features (1) four new basic Ph.D. courses; (2) industry participation in research projects; (3) formal job-readiness training with involvement of guest faculty from academia, government and industry. MPRTN activities since 2013 include 22 conferences; 7 workshops and 4 exchange travels. Three patents were filed or issued, nine awards/best papers were won. Fifteen journal publications were accepted/published, 102 conference abstracts. There are now 13 industry partners. Conclusion: A medical physics research training network has been set up with the goal to harness graduate student’s job-readiness for industry, government and academia in addition to the conventional clinical role. Two years after inception, significant successes have been booked, but the true challenge will be to demonstrate that with this training philosophy CREATE scholars gain access to a much broader job market.

Deletion of SLC19A2, the high affinity thiamine transporter, causes selective inner hair cell loss and an auditory neuropathy phenotype.

Liberman, M C; Tartaglini, E; Fleming, J C; Neufeld, E J

2006-09-01

Mutations in the gene coding for the high-affinity thiamine transporter Slc19a2 underlie the clinical syndrome known as thiamine-responsive megaloblastic anemia (TRMA) characterized by anemia, diabetes, and sensorineural hearing loss. To create a mouse model of this disease, a mutant line was created with targeted disruption of the gene. Cochlear function is normal in these mutants when maintained on a high-thiamine diet. When challenged with a low-thiamine diet, Slc19a2-null mice showed 40-60 dB threshold elevations by auditory brainstem response (ABR), but only 10-20 dB elevation by otoacoustic emission (OAE) measures. Wild-type mice retain normal hearing on either diet. Cochlear histological analysis showed a pattern uncommon for sensorineural hearing loss: selective loss of inner hair cells after 1-2 weeks on low thiamine and significantly greater inner than outer hair cell loss after longer low-thiamine challenges. Such a pattern is consistent with the observed discrepancy between ABR and OAE threshold shifts. The possible role of thiamine transport in other reported cases of selective inner hair cell loss is considered.

Unbiased multi-fidelity estimate of failure probability of a free plane jet

NASA Astrophysics Data System (ADS)

Marques, Alexandre; Kramer, Boris; Willcox, Karen; Peherstorfer, Benjamin

2017-11-01

Estimating failure probability related to fluid flows is a challenge because it requires a large number of evaluations of expensive models. We address this challenge by leveraging multiple low fidelity models of the flow dynamics to create an optimal unbiased estimator. In particular, we investigate the effects of uncertain inlet conditions in the width of a free plane jet. We classify a condition as failure when the corresponding jet width is below a small threshold, such that failure is a rare event (failure probability is smaller than 0.001). We estimate failure probability by combining the frameworks of multi-fidelity importance sampling and optimal fusion of estimators. Multi-fidelity importance sampling uses a low fidelity model to explore the parameter space and create a biasing distribution. An unbiased estimate is then computed with a relatively small number of evaluations of the high fidelity model. In the presence of multiple low fidelity models, this framework offers multiple competing estimators. Optimal fusion combines all competing estimators into a single estimator with minimal variance. We show that this combined framework can significantly reduce the cost of estimating failure probabilities, and thus can have a large impact in fluid flow applications. This work was funded by DARPA.

Potential Space Applications for Body-Centric Wireless and E-Textile Antennas

Kennedy, Timothy F.; Fink, Patrick W.; Chu, Andrew W.; Studor, George F.

2007-01-01

Space environment benefits of body-centric wireless communications are numerous, particularly in the context of long duration Lunar and Martian outposts that are in planning stages at several space agencies around the world. Since crew time for such missions is a scarce commodity, seamless integration of body-centric wireless from various sources is paramount. Sources include traditional data, such as audio, video, tracking, and biotelemetry. Newer data sources include positioning, orientation, and status of handheld tools and devices, as well as management and status of on-body inventories. In addition to offering lighter weight and flexibility, performance benefits of e-textile antennas are anticipated due to advantageous use of the body s surface area. In creating e-textile antennas and RF devices, researchers are faced with the challenge of transferring conventional and novel designs to textiles. Lack of impedance control, limited conductivity, and the inability to automatically create intricate designs are examples of limitations frequently attributed to e-textiles. Reliable interfaces between e-textiles and conventional hardware also represent significant challenges. Addressing these limitations is critical to the continued development and acceptance of fabric-based circuits for body-centric wireless applications. Here we present several examples of e-textile antennas and RF devices, created using a NASA-developed process, that overcome several of these limitations. The design and performance of an equiangular spiral, miniaturized spiral-loaded slot antenna, and a hybrid coupler are considered, with the e-textile devices showing comparable performance to like designs using conventional materials.

Objectives　Creating a healthy food environment is crucial for healthful longevity in Japan. This study aimed to provide an overview of the status and challenges related to creating that environment through prefectural public health centers.Methods　Public health dieticians working at 489 prefectural public health centers in March 2015 individually completed an anonymous self-administered questionnaire. Berelson's content analysis was utilized for response analysis.Results　Data from 359 (response rate: 74.3%) prefectural public health centers, involving 599 public health dieticians, were included in the analysis. More than 80% of the prefectural public health centers implemented a registration system for dining facilities such as restaurants. Furthermore, greater than 80% of the public health dietitians thought that creating a healthy food environment was an important aspect of their work mission. On the other hand, more than 50% of these dieticians expressed dissatisfaction in their role. In terms of evaluation, the public health centers only monitored the number of registered facilities, with few other evaluations conducted. Approximately 80% of the participants requested national guidelines and/or some legal support from the Ministry of Health, Labor, and Welfare and/or the prefectural administration.Conclusion　This study demonstrated that there are challenges related to creating a healthy food environment through prefectural health centers. Improving the evaluation methods and government/administrative provision of national guidelines and/or legal supports were identified as courses of action.

Bisphenol A and Risk Management Ethics

PubMed Central

Resnik, David B.; Elliot, Kevin C.

2013-01-01

It is widely recognized that endocrine disrupting compounds, such as Bisphenol A, pose challenges for traditional paradigms in toxicology, insofar as these substances appear to have a wider range of low-dose effects than previously recognized. These compounds also pose challenges for ethics and policymaking. When a chemical does not have significant low-dose effects, regulators can allow it to be introduced into commerce or the environment, provided that procedures and rules are in place to keep exposures below an acceptable level. This option allows society to maximize the benefits from the use of the chemical while minimizing risks to human health or the environment, and it represents a compromise between competing values. When it is not possible to establish acceptable exposure levels for chemicals that pose significant health or environmental risks, the most reasonable options for risk management may be to enact either partial or complete bans on their use. These options create greater moral conflict than other risk management strategies, leaving policymakers difficult choices between competing values. PMID:24471646

HIV and Mycobacterium tuberculosis (MTB) are two widespread and highly successful microbes whose synergy in pathogenesis has created a significant threat for human health globally. In acknowledgement of this fact, the European Union (EU) has funded a multinational support action, the European Network for global cooperation in the field of AIDS and TB (EUCO-Net), that brings together experts from Europe and those regions that bear the highest burden of HIV/MTB co-infection. Here, we summarise the main outcome of the EUCO-Net project derived from an expert group meeting that took place in Stellenbosch (South Africa) (AIDS/TB Workshop on Research Challenges and Opportunities for Future Collaboration) and the subsequent discussions, and propose priority areas for research and concerted actions that will have impact on future EU calls.

Visual Analytics Tools for Sustainable Lifecycle Design: Current Status, Challenges, and Future Opportunities.

PubMed

Ramanujan, Devarajan; Bernstein, William Z; Chandrasegaran, Senthil K; Ramani, Karthik

2017-01-01

The rapid rise in technologies for data collection has created an unmatched opportunity to advance the use of data-rich tools for lifecycle decision-making. However, the usefulness of these technologies is limited by the ability to translate lifecycle data into actionable insights for human decision-makers. This is especially true in the case of sustainable lifecycle design (SLD), as the assessment of environmental impacts, and the feasibility of making corresponding design changes, often relies on human expertise and intuition. Supporting human sense-making in SLD requires the use of both data-driven and user-driven methods while exploring lifecycle data. A promising approach for combining the two is through the use of visual analytics (VA) tools. Such tools can leverage the ability of computer-based tools to gather, process, and summarize data along with the ability of human-experts to guide analyses through domain knowledge or data-driven insight. In this paper, we review previous research that has created VA tools in SLD. We also highlight existing challenges and future opportunities for such tools in different lifecycle stages-design, manufacturing, distribution & supply chain, use-phase, end-of-life, as well as life cycle assessment. Our review shows that while the number of VA tools in SLD is relatively small, researchers are increasingly focusing on the subject matter. Our review also suggests that VA tools can address existing challenges in SLD and that significant future opportunities exist.

Cybersecurity and Optimization in Smart “Autonomous” Buildings

Mylrea, Michael E.; Gourisetti, Sri Nikhil Gup

Significant resources have been invested in making buildings “smart” by digitizing, networking and automating key systems and operations. Smart autonomous buildings create new energy efficiency, economic and environmental opportunities. But as buildings become increasingly networked to the Internet, they can also become more vulnerable to various cyber threats. Automated and Internet-connected buildings systems, equipment, controls, and sensors can significantly increase cyber and physical vulnerabilities that threaten the confidentiality, integrity, and availability of critical systems in organizations. Securing smart autonomous buildings presents a national security and economic challenge to the nation. Ignoring this challenge threatens business continuity and the availability ofmore » critical infrastructures that are enabled by smart buildings. In this chapter, the authors address challenges and explore new opportunities in securing smart buildings that are enhanced by machine learning, cognitive sensing, artificial intelligence (AI) and smart-energy technologies. The chapter begins by identifying cyber-threats and challenges to smart autonomous buildings. Then it provides recommendations on how AI enabled solutions can help smart buildings and facilities better protect, detect and respond to cyber-physical threats and vulnerabilities. Next, the chapter will provide case studies that examine how combining AI with innovative smart-energy technologies can increase both cybersecurity and energy efficiency savings in buildings. The chapter will conclude by proposing recommendations for future cybersecurity and energy optimization research for examining AI enabled smart-energy technology.« less

Supracolloidal fullerene-like cages: design principles and formation mechanisms.

PubMed

Li, Zhan-Wei; Zhu, You-Liang; Lu, Zhong-Yuan; Sun, Zhao-Yan

2016-11-30

How to create novel desired structures by rational design of building blocks represents a significant challenge in materials science. Here we report a conceptually new design principle for creating supracolloidal fullerene-like cages through the self-assembly of soft patchy particles interacting via directional nonbonded interactions by mimicking non-planar sp 2 hybridized carbon atoms in C 60 . Our numerical investigations demonstrate that the rational design of patch configuration, size, and interaction can drive soft three-patch particles to reversibly self-assemble into a vast collection of supracolloidal fullerene-like cages. We further elucidate the formation mechanisms of supracolloidal fullerene-like cages by analyzing the structural characteristics and the formation process. Our results provide conceptual and practical guidance towards the experimental realization of supracolloidal fullerene-like cages, as well as a new perspective on understanding the fullerene formation mechanisms.

Cognitive behavioral game design: a unified model for designing serious games

Starks, Katryna

2014-01-01

Video games have a unique ability to engage, challenge, and motivate, which has led teachers, psychology specialists, political activists and health educators to find ways of using them to help people learn, grow and change. Serious games, as they are called, are defined as games that have a primary purpose other than entertainment. However, it is challenging to create games that both educate and entertain. While game designers have embraced some psychological concepts such as flow and mastery, understanding how these concepts work together within established psychological theory would assist them in creating effective serious games. Similarly, game design professionals have understood the propensity of video games to teach while lamenting that educators do not understand how to incorporate educational principles into game play in a way that preserves the entertainment. Bandura (2006) social cognitive theory (SCT) has been used successfully to create video games that create positive behavior outcomes, and teachers have successfully used Gardner’s (1983) theory of multiple intelligences (MIs) to create engaging, immersive learning experiences. Cognitive behavioral game design is a new framework that incorporates SCT and MI with game design principles to create a game design blueprint for serious games. PMID:24550858

The expansion of newborn screening (NBS) is increasing the generation of incidental results, notably carrier results. Although carrier status is generally understood to be clinically benign, concerns persist that parents may misunderstand its meaning, with deleterious effects on children and their families. Expansion of the NBS panel in Ontario, Canada in 2006 to include sickle cell disorders drew attention to the policy challenge of incidental carrier results. We conducted a study of consumer and provider attitudes to inform policy on disclosure. In this paper, we report the results of (i) qualitative interviews with health-care providers, advocates and parents of carrier infants and (ii) focus groups with new parents and individuals active with the sickle cell community. Lay and provider participants generally believed that carrier results were clinically insignificant. However, some uncertainty persisted among lay consumers in the form of conjecture or doubt. In addition, consumers and advocates who were most informed about the disease articulated insistent yet dissonant claims of clinical significance. Meanwhile, providers referenced research knowledge to offer an equivocal assessment of the possibility and significance of clinically symptomatic carrier status. We conclude that many interpretations of carrier status are in circulation, failing to fit neatly into the categories of ‘clinically significant' or ‘benign.' This creates challenges for communicating clearly with parents – challenges exacerbated by inconsistent messages from screening programs regarding the significance of sickle cell carrier status. Disclosure policy related to incidentally generated infant carrier results needs to account for these complex realities. PMID:19809482

Maximizing research study effectiveness in malaria elimination settings: a mixed methods study to capture the experiences of field-based staff.

In a drug-resistant, malaria elimination setting like Western Cambodia, field research is essential for the development of novel anti-malarial regimens and the public health solutions necessary to monitor the spread of resistance and eliminate infection. Such field studies often face a variety of similar implementation challenges, but these are rarely captured in a systematic way or used to optimize future study designs that might overcome similar challenges. Field-based research staff often have extensive experience and can provide valuable insight regarding these issues, but their perspectives and experiences are rarely documented and seldom integrated into future research protocols. This mixed-methods analysis sought to gain an understanding of the daily challenges encountered by research field staff in the artemisinin-resistant, malaria elimination setting of Western Cambodia. In doing so, this study seeks to understand how the experiences and opinions of field staff can be captured, and used to inform future study designs. Twenty-two reports from six field-based malaria studies conducted in Western Cambodia were reviewed using content analysis to identify challenges to conducting the research. Informal Interviews, Focus Group Discussions and In-depth Interviews were also conducted among field research staff. Thematic analysis of the data was undertaken using Nvivo 9 ® software. Triangulation and critical case analysis was also used. There was a lack of formalized avenues through which field workers could report challenges experienced when conducting the malaria studies. Field research staff faced significant logistical barriers to participant recruitment and data collection, including a lack of available transportation to cover long distances, and the fact that mobile and migrant populations (MMPs) are usually excluded from studies because of challenges in follow-up. Cultural barriers to communication also hindered participant recruitment and created unexpected delays. Field staff often paid a physical, emotional and financial cost, going beyond their duty in order to keep the study running. Formal monthly reports filled out by field study staff could be a key tool for capturing field study staff experiences effectively, but require specific report fields to encourage staff to outline their challenges and to propose potential solutions. Forging strong bonds with communities and their leaders may improve communication, and decrease barriers to participant recruitment. Study designs that make it feasible for MMPs to participate should be pursued; in addition to increasing the potential participant pool, this will ensure that the most malaria-endemic demographic is taken into account in research studies. Overlaps between clinical care and research create ethical dilemmas for study staff, a fact that warrants careful consideration. Lessons learned from study field staff should be used to create a set of locally-relevant recommendations to inform future study designs.

The ERA project was created in 2009 as part of NASAs Aeronautics Research Mission Directorates (ARMD) Integrated Systems Aviation Program (IASP). The purpose of the ERA project was to explore and document the feasibility, benefit, and technical risk of vehicles concepts and enabling technologies to reduce aviations impact on the environment. The metrics for this technology is given in Figure 1 with the N+2 metrics highlighted in green. It is anticipated that the United States air transportation system will continue to expand significantly over the next few decades thus adversely impacting the environment unless new technology is incorporated to simultaneously reduce nitrous oxides (NOx), noise and fuel consumption. In order to achieve the overall goals and meet the technology insertion challenges, these goals were divided into technical challenges that were to be achieved during the execution of the ERA project. Technical challenges were accomplished through test campaigns conducted by Integrated Technology Demonstration (ITDs). ERAs technical performance period ended in 2015.

Environmental justice (EJ) research requires attention to consequences for research participants beyond those typically considered by institutional review boards. The imbalance of power between impacted communities and those who create and regulate pollution creates challenges for participation, yet research can also benefit those involved. Our community-academic partnership designed the Rural Air Pollutants and Children's Health (RAPCH) study to provide positive impacts while measuring health effects at three low-resource public middle schools near concentrated animal feeding operations (CAFOs) in North Carolina. We evaluated perceived benefits and challenges of study involvement by interviewing school staff and community liaisons who facilitated data collection. Reported benefits included enhancement of students' academic environment and increased community environmental awareness; challenges were associated mainly with some participants' immaturity. Leadership from a strong community-based organization was crucial to recruitment, yet our approach entailed minimal focus on EJ, which may have limited opportunities for community education or organizing for environmental health.

Satellite Level 2 data presents unique challenges for tools and services. From nonlinear spatial geometry to inhomogeneous file data structure to inconsistent temporal variables to complex data variable dimensionality to multiple file formats, there are many difficulties in creating general tools for Level 2 data support. At NASA Goddard Earth Sciences Data and Information Services Center (GES DISC), we are implementing a general Level 2 Subsetting service for Level 2 data. In this presentation, we will unravel some of the challenges faced in creating this service and the strategies we used to surmount them.

Creating a meaningful infection control program: one home healthcare agency's lessons.

Poff, Renee McCoy; Browning, Sarah Via

2014-03-01

Creating a meaningful infection control program in the home care setting proved to be challenging for agency leaders of one hospital-based home healthcare agency. Challenges arose when agency leaders provided infection control (IC) data to the hospital's IC Committee. The IC Section Chief asked for national benchmark comparisons to align home healthcare reporting to that of the hospital level. At that point, it was evident that the home healthcare IC program lacked definition and structure. The purpose of this article is to share how one agency built a meaningful IC program.

The relationship between participation in student-centered discussions and the academic achievement of fifth-grade science students

NASA Astrophysics Data System (ADS)

Mathues, Patricia Kelly

Although the social constructivist theory proposed by Vygotsky states the value of discourse as a contribution to the ability of the learner to create meaning, student-led discussions have often been relegated to the language arts classroom. The standards created by the National Council of Teachers of English and the International Reading Association have long recognized that learners create meaning in a social context. The National Science Education Standards have also challenged science teachers to facilitate discourse. However, the science standards document provides no specific structure through which such discourse should be taught. This study investigated the effectiveness of a discussion strategy provided by Shoop and Wright for teaching and conducting student-centered discussions (SCD). Fifth graders in one school were randomly selected and randomly assigned to one of two science classes; 22 students in one class learned and applied the SCD strategies while a second class with 19 students learned the same science concepts from a teacher using traditional methods as described by Cazden. This study used a pretest-posttest design to test the hypothesis that participation in SCD's would effect a difference in fifth-graders' abilities to comprehend science concepts. Results of independent-samples t-tests showed that while there was no significant difference between the mean ability scores of the two groups of subjects as measured by a standardized mental abilities test, the mean pretest score of the traditional group was significantly higher than the SCD group's mean pretest score. ANCOVA procedures demonstrated that the SCD group's mean posttest score was significantly higher than the mean posttest score of the traditional group. Data analysis supported the rejection of the null hypothesis. The investigator concluded that the SCD methodology contributed to students' understanding of the science concepts. Results of this study challenge content area teachers to provide direct instruction of the SCD strategies and to encourage students to engage in the construction of knowledge through such discourse. Future research should focus on the application of the SCD strategies in other settings and for various durations of time.

The Ultimate Destination: Choice of Interplanetary Exploration Path can define Future of Interstellar Spaceflight

NASA Astrophysics Data System (ADS)

Silin, D. V.

Manned interstellar spaceflight is facing multiple challenges of great magnitude; among them are extremely large distances and the lack of known habitable planets other than Earth. Many of these challenges are applicable to manned space exploration within the Solar System to the same or lesser degree. If these issues are resolved on an interplanetary scale, better position to pursue interstellar exploration can be reached. However, very little progress (if any) was achieved in manned space exploration since the end of Space Race. There is no lack of proposed missions, but all of them require considerable technological and financial efforts to implement while yielding no tangible benefits that would justify their costs. To overcome this obstacle highest priority in future space exploration plans should be assigned to the creation of added value in outer space. This goal can be reached if reductions in space transportation, construction and maintenance of space-based structures costs are achieved. In order to achieve these requirements several key technologies have to be mastered, such as near-Earth object mining, space- based manufacturing, agriculture and structure assembly. To keep cost and difficulty under control next exploration steps can be limited to nearby destinations such as geostationary orbit, low lunar orbit, Moon surface and Sun-Earth L1 vicinity. Completion of such a program will create a solid foundation for further exploration and colonization of the Solar System, solve common challenges of interplanetary and interstellar spaceflight and create useful results for the majority of human population. Another important result is that perception of suitable destinations for interstellar missions will change significantly. If it becomes possible to create habitable and self-sufficient artificial environments in the nearby interplanetary space, Earth-like habitable planets will be no longer required to expand beyond our Solar System. Large fraction of the stars in the observable Universe will become valid targets for interstellar missions.

to explore the cultural, social and economic needs and challenges of women in northern Ghana as they resume their day-to-day lives post obstetric fistula repair. a critical ethnographic approach. a state run fistula treatment center in Tamale, northern Ghana, and 24 rural communities in northern Ghana. ninety-nine (N=99) participants were recruited using purposive, convenience and snowball sampling. The sample consisted of women (N=41) who had experienced an obstetric fistula repair and their family members (N=24). Health care providers (N=17) and stakeholders (N=17) who had specialised knowledge about reintegration programs at a community or national level were also included. the needs and challenges of northern Ghanaian women post obstetric fistula repair were historically and culturally rooted. A woman's psychosocial acceptance back into her community post obstetric fistula was significant to her well-being but many women felt they had to 'prove' themselves worthy of acceptance and hid any signs of urinary incontinence post obstetric fistula repair. The cost of treatment compounded by a woman's inability to work while having the obstetric fistula exaggerated her economic needs. Skills training programs offered assistance but were often not suited to a woman's physical capability or geographic location. Many women who have experienced obstetric fistula along with women leaders have initiated obstetric fistula awareness campaigns in their communities with the aim of overcoming the challenges and improving the reintegration experiences of others who have had an obstetric fistula repair. developing understanding about the needs and challenges of women post obstetric fistula is an important step forward in creating social and political change in obstetric fistula care and reintegration. Strategies to support women reintegrating to their communities post obstetric fistula repair include exploring alternative forms of skills training and income generation activities, creating innovative pre and post obstetric fistula health education and community awareness to reduce the perception of the condition as 'incurable', and promoting peer advocacy.

Complex patients with multiple chronic conditions often face significant challenges communicating and coordinating with their primary care physicians. These challenges are exacerbated by the limited time allotted to primary care visits. Our aim was to employ a user-centered design process to create a tablet tool for use by patients for visit discussion prioritization. We employed user-centered design methods to create a tablet-based waiting room tool that enables complex patients to identify and set discussion topic priorities for their primary care visit. In an iterative design process, we completed one-on-one interviews with 40 patients and their 17 primary care providers, followed by three design sessions with a 12-patient group. We audiorecorded and transcribed all discussions and categorized major themes. In addition, we met with 15 key health communication, education, and technology leaders within our health system to further review the design and plan for broader implementation of the tool. In this paper, we present the significant changes made to the tablet tool at each phase of this design work. Patient feedback emphasized the need to make the tablet tool accessible for patients who lacked technical proficiency and to reduce the quantity and complexity of text presentation. Both patients and their providers identified specific content choices based on their personal experiences (eg, the ability to raise private or sensitive concerns) and recommended targeting new patients. Stakeholder groups provided essential input on the need to augment text with video and to create different versions of the videos to match sex and race/ethnicity of the actors with patients. User-centered design in collaboration with patients, providers, and key health stakeholders led to marked evolution in the initial content, layout, and target audience for a tablet waiting room tool intended to assist complex patients with setting visit discussion priorities.

Fontana, Jake; Ratna, Banahalli R

2015-11-01

Optical metamaterials have unique engineered optical properties. These properties arise from the careful organization of plasmonic elements. Transitioning these properties from laboratory experiments to functional materials may lead to disruptive technologies for controlling light. A significant issue impeding the realization of optical metamaterial devices is the need for robust and efficient assembly strategies to govern the order of the nanometer-sized elements while enabling macroscopic throughput. This mini-review critically highlights recent approaches and challenges in creating these artificial materials. As the ability to assemble optical metamaterials improves, new unforeseen opportunities may arise for revolutionary optical devices.

Southeast Asia faces a diabetes epidemic, which has created significant challenges for health care. The unique Asian diabetes phenotype, coupled with peculiar lifestyle, diet, and healthcare-seeking behavior, makes it imperative to develop clinical pathways and guidelines which address local needs and requirements. From an insulin-centric viewpoint, the preparations prescribed in such pathways should be effective, safe, well tolerated, nonintrusive, and suitable for the use in multiple clinical situations including initiation and intensification. This brief communication describes the utility of premixed or dual action insulin in such clinical pathways and guidelines.

LASR-Guided Variability Subtraction: The Linear Algorithm for Significance Reduction of Stellar Seismic Activity

NASA Astrophysics Data System (ADS)

Horvath, Sarah; Myers, Sam; Ahlers, Johnathon; Barnes, Jason W.

2017-10-01

Stellar seismic activity produces variations in brightness that introduce oscillations into transit light curves, which can create challenges for traditional fitting models. These oscillations disrupt baseline stellar flux values and potentially mask transits. We develop a model that removes these oscillations from transit light curves by minimizing the significance of each oscillation in frequency space. By removing stellar variability, we prepare each light curve for traditional fitting techniques. We apply our model to $\\delta$-Scuti KOI-976 and demonstrate that our variability subtraction routine successfully allows for measuring bulk system characteristics using traditional light curve fitting. These results open a new window for characterizing bulk system parameters of planets orbiting seismically active stars.

2007-01-01

Physicians practice at the intersection of medicine, law, and business. Each discipline creates its own challenges for the practicing physician: to practice efficient, effective medicine; to limit potential liability; and to create a positive financial outcome. Those challenges increase with escalating costs and reduced reimbursements. In this paper, the common clinical presentation of chest pain has been used to create a paradigm to educate physicians to understand efficient and effective approaches to diagnosis and treatment, and how effective communication with patients and meticulous documentation of all medical encounters can limit the potential for liability. Ultimately, given today's reimbursement formulas, physicians must also understand the cost of testing, in relation to its benefits, in an attempt to yield a positive financial outcome.

Creating a public space and dialogue on sexuality and rights: a case study from Bangladesh.

Rashid, Sabina Faiz; Standing, Hilary; Mohiuddin, Mahrukh; Ahmed, Farah Mahjabeen

2011-06-16

This article describes and analyses a research based engagement by a university school of public health in Bangladesh aimed at raising public debate on sexuality and rights and making issues such as discrimination more visible to policy makers and other key stakeholders in a challenging context. The impetus for this work came from participation in an international research programme with a particular interest in bridging international and local understandings of sexual and reproductive rights. The research team worked to create a platform to broaden discussions on sexuality and rights by building on a number of research activities on rural and urban men's and women's sexual health concerns, and on changing concepts of sexuality and understandings of sexual rights among specific population groups in Dhaka city, including sexual minorities. Linked to this on-going process of improving the evidence base, there has been a series of learning and capacity building activities over the last four years consisting of training workshops, meetings, conferences and dialogues. These brought together different configurations of stakeholders - members of sexual minorities, academics, service providers, advocacy organisations, media and policy makers. This process contributed to developing more effective advocacy strategies through challenging representations of sexuality and rights in the public domain. Gradually, these efforts brought visibility to hidden or stigmatised sexuality and rights issues through interim outcomes that have created important steps towards changing attitudes and policies. These included creating safe spaces for sexual minorities to meet and strategise, development of learning materials for university students and engagement with legal rights groups on sexual rights. Through this process, it was found to be possible to create a public space and dialogue on sexuality and rights in a conservative and challenging environment like Bangladesh by bringing together a diverse group of stakeholders to successfully challenge representations of sexuality in the public arena. A further challenge for BRAC University has been to assess its role as a teaching and research organisation, and find a balance between the two roles of research and activism in doing work on sexuality issues in a very sensitive political context.

Application of In Vitro Transposon Mutagenesis to Erythromycin Strain Improvement in Saccharopolyspora erythraea.

PubMed

Weber, J Mark; Reeves, Andrew; Cernota, William H; Wesley, Roy K

2017-01-01

Transposon mutagenesis is an invaluable technique in molecular biology for the creation of random mutations that can be easily identified and mapped. However, in the field of microbial strain improvement, transposon mutagenesis has scarcely been used; instead, chemical and physical mutagenic methods have been traditionally favored. Transposons have the advantage of creating single mutations in the genome, making phenotype to genotype assignments less challenging than with traditional mutagens which commonly create multiple mutations in the genome. The site of a transposon mutation can also be readily mapped using DNA sequencing primer sites engineered into the transposon termini. In this chapter an in vitro method for transposon mutagenesis of Saccharopolyspora erythraea is presented. Since in vivo transposon tools are not available for most actinomycetes including S. erythraea, an in vitro method was developed. The in vitro method involves a significant investment in time and effort to create the mutants, but once the mutants are made and screened, a large number of highly relevant mutations of direct interest to erythromycin production can be found.

Engineering long term clinical success of advanced ceramic prostheses.

PubMed

Rekow, Dianne; Thompson, Van P

2007-01-01

Biocompatability and, in some applications, esthetics make all-ceramic prostheses compelling choices but despite significant improvements in materials properties and toughening mechanisms, these still have significant failure rates. Factors that contribute to the degradation in strength and survival include material selection and prosthesis design which set the upper limit for performance. However, fabrication operations introduce damage that can be exacerbated by environmental conditions and clinical function. Using all-ceramic dental crowns as an example, experimentally derived models provide insight into the relationships between materials properties and initial critical loads to failure. Analysis of fabrication operations suggests strategies to minimize damage. Environmental conditions can create viscoplastic flow of supporting components which can contribute additional stress within the prosthesis. Fatigue is a particularly challenging problem, not only providing the energy to propagate existing damage but, when combined with the wet environment, can create new damage modes. While much is known, the influence of these new damage modes has not been completely elucidated. The role of complex prosthesis geometry and its interaction with other factors on damage initiation and propagation has yet to be well characterized.

Challenges faced by former child soldiers in the aftermath of war in Uganda.

Warfare takes a profound toll of all layers of society, creating multiple and multilevel challenges that impinge on the psychosocial well-being of affected individuals. This study aims to assess the scope and salience of challenges confronting former child soldiers and at identifying additional challenges they face compared to non-recruited young people in war-affected northern Uganda. The study was carried out with a stratified random sample of northern Ugandan adolescents (n = 1,008), of whom a third had formerly been recruited (n = 330). The mixed-method comparison design consisted of a constrained free listing task to determine the challenges; a free sorting task to categorize them into clusters; and statistical analysis of their prevalence among formerly recruited youth and of how they compare with those of nonrecruited youth. Altogether, 237 challenges were identified and clustered into 15 categories, showing that formerly recruited participants mainly identified "emotional" and "training and skills"-related challenges. Compared with nonrecruited counterparts, they reported significantly more "emotional" and fewer "social and relational" challenges, with the exception of stigmatization. Overall, there was similarity between the challenges reported by both groups. The challenges confronting formerly recruited youths reach well beyond the effects of direct war exposure and emerge mainly from multiple influence spheres surrounding them. These challenges are largely shared in common with nonrecruited youths. This multidimensional and collective character of challenges calls for comprehensive psychosocial interventions through which healing the psychological wounds of war is complemented by mending the war-affected surroundings at all levels and in all life areas.

2016-01-01

Audiologists managing children with auditory processing disorders (APD) encounter challenges that include conflicting definitions, several classification profiles, problems with differential diagnosis and a lack of standardised guidelines. The heterogeneity of the disorder and its concomitant childhood disorders makes diagnosis difficult. Linguistic and cultural issues are additional challenges faced by South African audiologists. The study aimed to describe the practices, challenges and recommendations of South African audiologists managing children with APD. A quantitative, non-experimental descriptive survey was used to obtain data from 156 audiologists registered with the Health Professions of South Africa. Findings revealed that 67% screened for APD, 42% assessed while 43% provided intervention. A variety of screening and assessment procedures were being administered, with no standard test battery identified. A range of intervention strategies being used are discussed. When the relationship between the number of years of experience and the audiologists’ level of preparedness to practice in the field of APD was compared, a statistically significant difference (p = 0.049) was seen in that participants with more than 10 years of experience were more prepared to practice in this area. Those participants having qualified as speech-language therapists and audiologists were significantly more prepared (p = 0.03) to practice than the audiologists who comprised the sample. Challenges experienced by the participants included the lack of linguistically and culturally appropriate screening and assessment tools and limited normative data. Recommendations included reviewing the undergraduate audiology training programmes, reinstituting the South African APD Taskforce, developing linguistically and culturally appropriate normative data, creating awareness among educators and involving them in the multidisciplinary team.

Creating student awareness to improve cultural competence: creating the critical incident.

PubMed

Morell, Venita W; Sharp, Penny C; Crandall, Sonia J

2002-09-01

Teaching medical students to recognize the need for cultural competence and accept their shortcomings in this area is a challenge. A simulated patient scenario was developed to address this challenge. The objective of the simulation is to enhance students' readiness to learn by moving them from 'unconscious incompetence' to 'conscious incompetence'. The patient scenario presents a Cherokee Indian woman with a complaint of abnormal menstrual bleeding who is resistant to gynaecologic care from male providers. A faculty member facilitates a small-group videotape review of student interviews. As students discuss their encounters, they realize they 'misdiagnose' and mishandle the interview. They are confronted by their inability to recognize cultural cues and the impact they may have on health outcomes and begin to question whether cultural beliefs are affecting the care of other patients. This simulation creates an eye-opening situation that must be handled carefully. This activity is an effective method to create awareness in students who feel they 'know all this stuff.'

Will a catch share for whales improve social welfare?

PubMed

Smith, Martin D; Asche, Frank; Bennear, Lori S; Havice, Elizabeth; Read, Andrew J; Squires, Dale

2014-01-01

We critique a proposal to use catch shares to manage transboundary wildlife resources with potentially high non-extractive values, and we focus on the case of whales. Because whales are impure public goods, a policy that fails to capture all nonmarket benefits (due to free riding) could lead to a suboptimal outcome. Even if free riding were overcome, whale shares would face four implementation challenges. First, a whale share could legitimize the international trade in whale meat and expand the whale meat market. Second, a legal whale trade creates monitoring and enforcement challenges similar to those of organizations that manage highly migratory species such as tuna. Third, a whale share could create a new political economy of management that changes incentives and increases costs for nongovernmental organizations (NGOs) to achieve the current level of conservation. Fourth, a whale share program creates new logistical challenges for quota definition and allocation regardless of whether the market for whale products expands or contracts. Each of these issues, if left unaddressed, could result in lower overall welfare for society than under the status quo.

Computer-aided 3D printing approaches to the industrial production of customized 3D functional living constructs for restoration of tissue and organ function face significant regulatory challenges. Using the manufacture of a customized, 3D-bioprinted nasal implant as a well-informed but hypothetical exemplar, we examine how these products might be regulated. Existing EU and USA regulatory frameworks do not account for the differences between 3D printing and conventional manufacturing methods or the ability to create individual customized products using mechanized rather than craft approaches. Already subject to extensive regulatory control, issues related to control of the computer-aided design to manufacture process and the associated software system chain present additional scientific and regulatory challenges for manufacturers of these complex 3D-bioprinted advanced combination products.

Oil shale development and its environmental considerations

USGS Publications Warehouse

Stone, R.T.; Johnson, H.; Decora, A.

1974-01-01

The petroleum shortage recently experienced by many nations throughout the world has created an intense interest in obtaining new and supplemental energy sources. In the United States, this interest has been centered on oil shale. Any major action by the federal government having significant environmental effects requires compliance with the National Environmental Policy Act of 1969 (NEPA). Since most oil shale is found on federal lands, and since its development involves significant environmental impacts, leasing oil shale lands to private interests must be in compliance with NEPA. For oil shale, program planning began at approximately the same time that NEPA was signed into law. By structuring the program to permit a resource and technological inventory by industry and the federal agencies, the Department of the Interior was able simultaneously to conduct the environmental assessments required by the act. This required: 1. Clearly defined program objections; 2. An organization which could integrate public policy with diverse scientific disciplines and environmental concerns; and 3. Flexible decisionmaking to adjust to policy changes as well as to evolving interpretations on EPA as clarified by court decisions. This paper outlines the program, the organization structure that was created for this specific task, and the environmental concerns which were investigated. The success of the program has been demonstrated by meeting the requirements of NEPA, without court challenge, and by industry's acceptance of a leasing program that included the most stringent environmental protection provisions ever required. The need for energy development has spurred the acceptance of the program. However, by its awareness and willingness to meet the environmental challenges of the future, industry has shown a reasonable understanding of its commitments. The pros and cons of development were publicly considered in hearings and analyzed in the final environmental statement. This action aided greatly in preventing legal challenges. The prototype oil shale program is now under way and this new energy source, developed with strict environmental safeguards, may soon be available to our nation.

Fluid-Structure Interaction Modeling of the Reefed Stages of the Orion Spacecraft Main Parachutes

NASA Astrophysics Data System (ADS)

Boswell, Cody W.

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

Understanding the space of nursing practice in Colombia: A critical reflection on the effects of health system reform.

PubMed

Camargo Plazas, Pilar

2018-04-11

Worldwide, healthcare has been touched by neoliberal policies to the extent that it has some of its characteristics, such as being asymmetrical, competitive, dehumanized, and profit driven. In Colombia, Law 100/93 was created as an ambitious reform aimed at integrating the social security and public sectors of healthcare in order to create universal access, and at the same time to generate market competence with the objective of improving effectiveness and responsiveness. Instead, however, Colombian health reform has served to generate competition which has aggravated inequalities among people. Within this context, we practice nursing. As nurses, our responsibility is to advocate for our patients. We cannot ignore what is happening worldwide in hospitals and community health settings because our responsibility is to promote health, prevent disease, and care for human beings. So, today, when the world pushes for economical profit and competence on one hand, and, on the other, for moral compromises to care, respect, and advocacy for all human beings, being a nurse in the Colombian health system represents a challenge for us. This challenge is especially significant because harm and benefit, justice and injustice, respect and disrespect are separated by a fine line that is easy to transgress. © 2018 John Wiley & Sons Ltd.

An Efficient, FPGA-Based, Cluster Detection Algorithm Implementation for a Strip Detector Readout System in a Time Projection Chamber Polarimeter

NASA Technical Reports Server (NTRS)

Gregory, Kyle J.; Hill, Joanne E. (Editor); Black, J. Kevin; Baumgartner, Wayne H.; Jahoda, Keith

2016-01-01

A fundamental challenge in a spaceborne application of a gas-based Time Projection Chamber (TPC) for observation of X-ray polarization is handling the large amount of data collected. The TPC polarimeter described uses the APV-25 Application Specific Integrated Circuit (ASIC) to readout a strip detector. Two dimensional photoelectron track images are created with a time projection technique and used to determine the polarization of the incident X-rays. The detector produces a 128x30 pixel image per photon interaction with each pixel registering 12 bits of collected charge. This creates challenging requirements for data storage and downlink bandwidth with only a modest incidence of photons and can have a significant impact on the overall mission cost. An approach is described for locating and isolating the photoelectron track within the detector image, yielding a much smaller data product, typically between 8x8 pixels and 20x20 pixels. This approach is implemented using a Microsemi RT-ProASIC3-3000 Field-Programmable Gate Array (FPGA), clocked at 20 MHz and utilizing 10.7k logic gates (14% of FPGA), 20 Block RAMs (17% of FPGA), and no external RAM. Results will be presented, demonstrating successful photoelectron track cluster detection with minimal impact to detector dead-time.

Creating a table of authorization to empower staff.

PubMed

Freed, D H

1997-11-01

Empowering frontline managers to make and accept accountability for decisions poses a significant challenge, especially for integrated delivery systems (IDSs) where multiple organizational layers and complex management structures can create confusion about roles and responsibilities. Without a clear set of guidelines for independent action, attempts to achieve staff empowerment are likely to fail. To achieve its empowerment goals, Overlook Hospital in Summit, New Jersey, a part of the Atlantic Health System, a New Jersey-based IDS, developed the "Table of Authorization for the Commitment or Expenditure of the System's Physical or Financial Resources." This management tool clarifies the degree to which frontline managers may make decisions and initiate actions without the need for senior management or board approval. The table provides an effective means of promoting a uniform basis for decision making across the system and encourages improved customer service vital in competitive markets.

Creating Nurturing Environments: A Science-Based Framework for Promoting Child Health and Development within High-Poverty Neighborhoods

Living in poverty and living in areas of concentrated poverty pose multiple risks for child development and for overall health and wellbeing. Poverty is a major risk factor for several mental, emotional, and behavioral disorders, as well as for other developmental challenges and physical health problems. In this paper, the Promise Neighborhoods Research Consortium describes a science-based framework for the promotion of child health and development within distressed high-poverty neighborhoods. We lay out a model of child and adolescent developmental outcomes, and integrate knowledge of potent and malleable influences to define a comprehensive intervention framework to bring about a significant increase in the proportion of young people in high-poverty neighborhoods who will develop successfully. Based on a synthesis of research from diverse fields, we designed the Creating Nurturing Environments framework to guide community-wide efforts to improve child outcomes and reduce health and educational inequalities.

Epigenetic Inheritance: A Contributor to Species Differentiation?

PubMed Central

Boffelli, Dario

2012-01-01

Multiple epigenetic states can be associated with the same genome, and transmitted through the germline for generations, to create the phenomenon of epigenetic inheritance. This form of inheritance is mediated by complex and highly diverse components of the chromosome that associate with DNA, control its transcription, and are inherited alongside it. But, how extensive, and how stable, is the information carried in the germline by the epigenome? Several known examples of epigenetic inheritance demonstrate that it has the ability to create selectable traits, and thus to mediate Darwinian evolution. Here we discuss the possibility that epigenetic inheritance is responsible for some stable characteristics of species, focusing on a recent comparison of the human and chimpanzee methylomes which reveals that somatic methylation states are related to methylation states in the germline. Interpretation of this finding highlights the potential significance of germline epigenetic states, as well as the challenge of investigating a form of inheritance with complex and unfamiliar rules.

Deep nursing: a thoughtful, co-created nursing process.

PubMed

Griffiths, Colin

2017-03-30

This article examines some of the challenges in nursing practice experienced by patients and nurses in the UK and Ireland, and considers some of the associated stressors in the system. Nurses must respond to these challenges by crafting their own practice, and the article offers a blueprint for developing personal nursing practice through acceptance, paying detailed attention to patients, taking time with patients and personal reflection. It draws on innovations in learning disability practice to suggest that care should be jointly thought through and co-created by patients and nurses, and that this process of thoughtful engagement constitutes 'deep nursing'.

Electrofuels: A New Paradigm for Renewable Fuels

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

Conrado, Robert J.; Haynes, Chad A.; Haendler, Brenda E.

2013-01-01

Biofuels are by now a well-established component of the liquid fuels market and will continue to grow in importance for both economic and environmental reasons. To date, all commercial approaches to biofuels involve photosynthetic capture of solar radiation and conversion to reduced carbon; however, the low efficiency inherent to photosynthetic systems presents significant challenges to scaling. In 2009, the US Department of Energy (DOE) Advanced Research Projects Agency-Energy (ARPA-E) created the Electrofuels program to explore the potential of nonphotosynthetic autotrophic organisms for the conversion of durable forms of energy to energy-dense, infrastructure-compatible liquid fuels. The Electrofuels approach expands the boundariesmore » of traditional biofuels and could offer dramatically higher conversion efficiencies while providing significant reductions in requirements for both arable land and water relative to photosynthetic approaches. The projects funded under the Electrofuels program tap the enormous and largely unexplored diversity of the natural world, and may offer routes to advanced biofuels that are significantly more efficient, scalable and feedstock-flexible than routes based on photosynthesis. Here, we describe the rationale for the creation of the Electrofuels program, and outline the challenges and opportunities afforded by chemolithoautotrophic approaches to liquid fuels.« less

2012-09-01

A small number of patients representing a significant demand on emergency department (ED) services present regularly for a variety of reasons, including psychiatric or behavioral complaints and lack of access to other services. A care plan program was created as a database of ED high users and patients of concern, as identified by ED staff and approved by program administrators to improve care and mitigate ED strain. A list of medical record numbers was assembled by searching the care plan program database for adult patients initially enrolled between the dates of November 1, 2006, and October 21, 2007. Inclusion criteria were the occurrence of a psychiatric International Classification Diseases, Ninth Revision, code in their medical record and a care plan level implying a serious psychiatric disorder causing harmful behavior. Additional data about these patients were acquired using an indigent care tracking database and electronic medical records. Variables collected from these sources were analyzed for changes before and after program enrollment. Of 501 patients in the database in the period studied, 48 patients fulfilled the criteria for the cohort. There was a significant reduction in the number of visits to the ED from the year before program enrollment to the year after enrollment (8.9, before; 5.9, after; P < .05). There was also an increase in psychiatric hospital visits (2%, before; 25%, after; P < .05). An alert program that identifies challenging ED patients with psychiatric conditions and creates a care plan appears to reduce visits and lead to more appropriate use of other resources.

Ralph G. Bennett

2008-12-01

The United States is facing unprecedented challenges in climate change and energy security. President-elect Obama has called for a reduction of CO2 emissions to 1990 levels by 2020, with a further 80% reduction by 2050. Meeting these aggressive goals while gradually increasing the overall energy supply requires that all non-emitting technologies must be advanced. The development and deployment of nuclear energy can, in fact, help the United States meet several key challenges: 1) Increase the electricity generated by non-emitting sources to mitigate climate change, 2) Foster the safe and proliferation-resistant use of nuclear energy throughout the world, 3) Reduce themore » transportation sector’s dependence on imported fossil fuels, and 4) Reduce the demand on natural gas for process heat and hydrogen production. However, because of the scale, cost, and time horizons involved, increasing nuclear energy’s share will require a coordinated research effort—combining the efforts of industry and government, supported by innovation from the research community. This report outlines the significant nuclear energy research and development (R&D) necessary to create options that will allow government and industrial decision-makers to set policies and create nuclear energy initiatives that are decisive and sustainable. The nuclear energy R&D strategy described in this report adopts the following vision: Safe and economical nuclear energy in the United States will expand to address future electric and non-electric needs, significantly reduce greenhouse gas emissions and provide energy diversity, while providing leadership for safe, secure and responsible expansion of nuclear energy internationally.« less

Six Challenges for Ethical Conduct in Science.

PubMed

Niemi, Petteri

2016-08-01

The realities of human agency and decision making pose serious challenges for research ethics. This article explores six major challenges that require more attention in the ethics education of students and scientists and in the research on ethical conduct in science. The first of them is the routinization of action, which makes the detection of ethical issues difficult. The social governance of action creates ethical problems related to power. The heuristic nature of human decision making implies the risk of ethical bias. The moral disengagement mechanisms represent a human tendency to evade personal responsibility. The greatest challenge of all might be the situational variation in people's ethical behaviour. Even minor situational factors have a surprisingly strong influence on our actions. Furthermore, finally, the nature of ethics itself also causes problems: instead of clear answers, we receive a multitude of theories and intuitions that may sometimes be contradictory. All these features of action and ethics represent significant risks for ethical conduct in science. I claim that they have to be managed within the everyday practices of science and addressed explicitly in research ethics education. I analyse them and suggest some ways in which their risks can be alleviated.

A dust explosion at the Formosa Fun Coast water park in Taiwan caused nearly 500 burn injury cases. One hundred of these cases involved burns over more than 20% of the total body surface area. This tragedy inundated hospitals across northern Taiwan with an unprecedented number of burn patients. Significant manpower and medical resources were targeted on related resuscitation and treatment efforts, with support and assistance provided by agencies and organizations nationwide. Most of the burn patients were young people in their teens and twenties, whose severe burns posed the greatest threat and challenge to their lives so far. Furthermore, their experience presented major psychosocial and physical health challenges. Patients received an array of clinical treatments such as debridement, skin grafting, dressing, and rehabilitation. Debilitating pain, skin damage, changes to body image, physical disabilities, helplessness, sadness, and anxiety have not only deeply affected the patients physically and psychologically but also created significant life stresses for their family members / companions, which requires counseling in order to facilitate emotional healing. Although burn patients gradually recover as they pass through the acute, recovery, and rehabilitation phases, they will face the challenges of lifelong rehabilitation after discharge. I hope that these young victims will take courage and be brave and strong in dealing with the difficulties and challenges of daily life and will embrace the future with hope as they enter the dawn of their new life.

Creating Student Engagement Through Immersion: Exploring the MT6 Shipwreck in Puget Sound via Submersible, Using a Team Challenge Format

NASA Astrophysics Data System (ADS)

Sarason, C. P.; Hartzler, R.; Anderson, A.

2016-02-01

Educational literature has many stories describing the "aha" moment that teachers are privileged to observe: a student who suddenly grasps a concept (ding!), dives into an activity (whee!) or works tirelessly to complete a complicated project (wow!). Designing moments like these for students can be one of the great joys of teaching. Experiencing such a moment can have a lasting impact on student engagement and motivation, and is the underlying rationale for the importance of creating a wide array of outreach efforts, from field work to telepresence activities.During the spring of 2015, OceanGate Foundation and Seattle Central College partnered on a pilot program to design a program that had this kind of impact and created the Open The Oceans Challenge. Student teams responded to our Request for Proposal (RFP), which was centered around the exploration of a shipwreck in 150 meters of water just off the Seattle waterfront, the MT-6. Students spent a significant amount of time crafting their proposals and reported that they enjoyed the process of writing the proposal as a team. The two winning teams accompanied us on a series of submersible dives performed by OceanGate, Inc. and worked up the results afterward. In addition to researching the MT-6 wreck and documenting what they found, students were able to do basic observational research on the wreck, providing sonar and photographic data that will help form the basis of future expeditions to this site.We report on lessons learned from this pilot — the impact for the small set of students involved in this project was profound, but how can we expand the reach of such activities? Results from this experience suggest that providing a highly engaging topic and expedition may not be enough to inspire an "aha" moment that creates lasting engagement; the scaffolding and mentorship that surrounds a rich experience is also critical.

CHALLENGES AND BENEFITS OF CONDUCTING ENVIRONMENTAL JUSTICE RESEARCH IN A SCHOOL SETTING

PubMed Central

GUIDRY, VIRGINIA T.; LOWMAN, AMY; HALL, DEVON; BARON, DOTHULA; WING, STEVE

2015-01-01

Environmental justice (EJ) research requires attention to consequences for research participants beyond those typically considered by institutional review boards. The imbalance of power between impacted communities and those who create and regulate pollution creates challenges for participation, yet research can also benefit those involved. Our community-academic partnership designed the Rural Air Pollutants and Children's Health (RAPCH) study to provide positive impacts while measuring health effects at three low-resource public middle schools near concentrated animal feeding operations (CAFOs) in North Carolina. We evaluated perceived benefits and challenges of study involvement by interviewing school staff and community liaisons who facilitated data collection. Reported benefits included enhancement of students’ academic environment and increased community environmental awareness; challenges were associated mainly with some participants’ immaturity. Leadership from a strong community-based organization was crucial to recruitment, yet our approach entailed minimal focus on EJ, which may have limited opportunities for community education or organizing for environmental health.

Recreational drugs. Societal and professional issues.

PubMed

Solari-Twadell, P A

1991-06-01

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

Vijayaraghavan, Ravi; Albert, Sam; Singh, Vinod Kumar; Kannan, Pallipuram V.

With the coming of age of web as a mainstream customer service channel, B2C companies have invested substantial resources in enhancing their web presence. Today customers can interact with a company, not only through the traditional phone channel but also through chat, email, SMS or web self-service. Each of these channels is best suited for some services and ill-matched for others. Customer service organizations today struggle with the challenge of delivering seamlessly integrated services through these different channels. This paper will evaluate some of the key challenges in multi-channel customer service. It will address the challenge of creating the right channel mix i.e. providing the right choice of channels for a given customer/behavior/issue profile. It will also provide strategies for optimizing the performance of a given channel in creating the right customer experience.

1987-03-09

Mice with unilateal striatal lesions created by 6-hydroxydopamine (6HDA) injection were screened for rotational (circling) behavior in response to injection of amphetamine and apomorphine. Those that rotated ipsilaterally in response to amphetamine and contralaterally in response to apomorphine were subsequently challenged with 1 to 3 g/kg (i.p.) ethanol. Surprisingly, ethanol induced dose related contralateral (apomorphine-like) rotation which, despite gross intoxication, was quite marked in most animals. No significant correlation was found between the number of turns made following ethanol and made after apomorphine or amphetamine. 14 references, 2 figures, 1 table.

Southeast Asia faces a diabetes epidemic, which has created significant challenges for health care. The unique Asian diabetes phenotype, coupled with peculiar lifestyle, diet, and healthcare-seeking behavior, makes it imperative to develop clinical pathways and guidelines which address local needs and requirements. From an insulin-centric viewpoint, the preparations prescribed in such pathways should be effective, safe, well tolerated, nonintrusive, and suitable for the use in multiple clinical situations including initiation and intensification. This brief communication describes the utility of premixed or dual action insulin in such clinical pathways and guidelines. PMID:28553609

One of the challenges for achieving efficient exciton transport in solar energy conversion systems is precise structural control of the light-harvesting building blocks. Here, we create a tunable material consisting of a connected chromophore network on an ordered biological virus template. Using genetic engineering, we establish a link between the inter-chromophoric distances and emerging transport properties. The combination of spectroscopy measurements and dynamic modelling enables us to elucidate quantum coherent and classical incoherent energy transport at room temperature. Through genetic modifications, we obtain a significant enhancement of exciton diffusion length of about 68% in an intermediate quantum-classical regime.

The significant scientific and technological potential of terahertz (THz) wave sensing and imaging has been attracted considerable attention within many fields of research. However, the development of remote, broadband THz wave sensing technology is lagging behind the compelling needs that exist in the areas of astronomy, global environmental monitoring, and homeland security. This is due to the challenge posed by high absorption of ambient moisture in the THz range. Although various time-domain THz detection techniques have recently been demonstrated, the requirement for an on-site bias or forward collection of the optical signal inevitably prohibits their applications for remote sensing. The objective of this paper is to report updated THz air-plasma technology to meet this great challenge of remote sensing. A focused optical pulse (mJ pulse energy and femtosecond pulse duration) in gas creates a plasma, which can serve to generate intense, broadband, and directional THz waves in the far field.

Ebola viruses are highly pathogenic viruses that cause outbreaks of hemorrhagic fever in humans and other primates. To meet the need for a vaccine against the several types of Ebola viruses that cause human diseases, we developed a multivalent vaccine candidate (EBO7) that expresses the glycoproteins of Zaire ebolavirus (ZEBOV) and Sudan ebolavirus (SEBOV) in a single complex adenovirus-based vector (CAdVax). We evaluated our vaccine in nonhuman primates against the parenteral and aerosol routes of lethal challenge. EBO7 vaccine provided protection against both Ebola viruses by either route of infection. Significantly, protection against SEBOV given as an aerosol challenge, which has not previously been shown, could be achieved with a boosting vaccination. These results demonstrate the feasibility of creating a robust, multivalent Ebola virus vaccine that would be effective in the event of a natural virus outbreak or biological threat. PMID:20181765

The caries-conducive impact of xerostomia was studied in 42 irradiated cancer patients. The radiation-induced xerostomia was paralleled by changes in the physical, microbial, biochemical, immunologic and dietary parameters of cariogenicity that collectively comprised an overwhelming caries challenge. Microbiologically, significant xerostomia-related increases in Strep. mutans, lactobacilli, staphylococci, yeasts and catalase-positive diphtheroids were accompanied by decreases in Strep. sanguis, bacteroides and fusobacteria in each of the 5 microenvironments tested. The scanty xerostomic saliva contained greater amounts of Na(+), Cl(-), Ca(++), Mg(++), Prot(-), lysozyme, IgA and IgG and considerably less HCO3(-). The increased concentrations of caries protective electrolytes and immunoproteins were negated bymore » huge reductions in total daily saliva output. The xerostomia created caries challenge was almost completely neutralized by a preventive program of daily topical NaF applications and strict oral hygiene. (GRA)« less

2008-01-01

Recruitment is one of the most significant challenges in conducting research with ethnic minority populations. Establishing relationships with organizations that serve ethnic minority communities can facilitate recruitment. To create a successful recruitment process, a strategic plan of action is necessary prior to implementing community outreach efforts. For this study population of women who were HIV+ and recovering from substance abuse disorder, the authors found that establishing trust with community organizations that serve these women allows for a productive referral relationship. Although the majority of women in this study are African American, the authors were particularly challenged in recruiting Hispanic women. This article presents a recruitment process model that has facilitated our recruitment efforts and has helped the authors to organize, document, and evaluate their community outreach strategies. This model can be adopted and adapted by nurses and other health researchers to enhance engagement of minority populations. PMID:16829637

Brenner, Lisa A.; Bahraini, Nazanin; Hernández, Theresa D.

2012-01-01

Military personnel are returning from Iraq and Afghanistan and reporting non-specific physical (somatic), behavioral, psychological, and cognitive symptoms. Many of these symptoms are frequently associated with mild traumatic brain injury (mTBI) and/or post traumatic stress disorder (PTSD). Despite significant attention and advances in assessment and intervention for these two conditions, challenges persist. To address this, clinically relevant blast models are essential in the full characterization of this type of injury, as well as in the testing and identification of potential treatment strategies. In this publication, existing diagnostic challenges and current treatment practices for mTBI and/or PTSD will be summarized, along with suggestions regarding how what has been learned from existing models of PTSD and traditional mechanism (e.g., non-blast) traumatic brain injury can be used to facilitate the development of clinically relevant blast models.

Disease management: old wine in new bottles?

PubMed

Ritterband, D R

2000-01-01

Disease management is a holistic, patient-focused approach to the treatment of disease across the spectrum of healthcare delivery. In its current form, disease management was created in response to the societal and economic burden that chronic illness contributes. There has recently been rapid growth in the development of disease management programs and sponsors are widespread within the industry, with the largest increase in independent vendors. Although growth has been substantial, the hurdles these programs have encountered have kept them from reaching their full potential. The challenges that exist include clinical, financial, and regulatory issues, and these challenges have significant meaning to healthcare managers. In deciding whether to develop or enhance programs, executives must consider their capability of outcomes measurement, their provider relationships, and the arrangements for program implementation. Ultimately, if programs provide improved health and quality of life for participants, cost savings will follow.

One of the greatest challenges instructors face is getting students to connect with the subject in a manner that encourages them to learn. In this essay, we describe the redesign of our Developmental Biology course to foster a deeper connection between students and the field of developmental biology. In our approach, we created a community of scientific practice focused on the investigation of environmental impacts on embryonic development and informed by popular and scientific media, the students' own questions, and the instructor. Our goals were to engage students in meaningful ways with the material, to develop students' science process skills, and to enhance students' understanding of broad principles of developmental biology. Though significant challenges arose during implementation, assessments indicate using this approach to teach undergraduate developmental biology was successful.

2016-01-01

The welfare of captive bears became a big issue of concern in Poland when a case of a bear being ill-treated became a high-profile case in the media. This case created a challenge to verify, study, and understand the main problems associated with bear keeping so that zoos could significantly improve the conditions in which they keep bears or ensure they keep bears at the minimum required standards. The results presented here are from 1 of the few countrywide studies of captive bear conditions conducted in all the captive institutions in Poland that keep bears. Thirteen institutions kept bears at the time of the study (2007-2009), including 54 individuals of 5 species. Major welfare problems were identified, and the results have been used to challenge zoos to address the changes required and focus the government's attention on areas that require legislative improvement.

Family Wellness, Not HIV Prevention

PubMed Central

Swendeman, Dallas; Flannery, Diane

2010-01-01

HIV exceptionalism (and disease-specific programs generally) garner both unbalanced funding and the most talented personnel, distorting local health priorities. In support of HIV exceptionalism, the successful mobilization of significant global health sector resources was not possible prior to HIV. Both sides of the debate have merits; rather than perpetuating polarization, we suggest that sustained improvements in global health require creating a prevention infrastructure to meet multiple health challenges experienced by local communities. We propose four fundamental shifts in HIV and disease prevention: (1) horizontally integrating prevention at one site locally, with priorities tailored to local health challenges and managed by local community leaders; (2) using a family wellness metaphor for services, not disease prevention; (3) implementing evidence-based prevention programs (EBPP) based on common principles, factors, and processes, rather than replication of specific programs; and (4) utilizing the expertise of private enterprise to re-design EBPP into highly attractive, engaging, and accessible experiences.

Challenging and Preventing Policies That Prohibit Local Civil Rights Protections for Lesbian, Gay, Bisexual, Transgender, and Queer People.

Pomeranz, Jennifer L

2018-01-01

Discrimination causes health inequities for stigmatized groups. Lesbian, gay, bisexual, transgender, and queer (LGBTQ) individuals, in particular, are at significantly increased risk for disparate health outcomes when they reside in states that fail to extend equal protections to them or that actively deprive equal rights to them. Several states and the federal government have proposed or enacted laws that permit residents to discriminate against LGBTQ individuals. One such law, Arkansas's Intrastate Commerce Improvement Act of 2015, preempts or prohibits local governments from enacting civil rights protections for LGBTQ individuals that are also lacking at the state level. State laws such as Arkansas's undermine local control, damage the economy, and create injustices that harm LGBTQ people. I set forth 2 constitutional arguments to challenge such laws, and I provide information to help advocates support evidence-based policymaking and prevent the passage of similar laws in their states.

Ground Truth Creation for Complex Clinical NLP Tasks - an Iterative Vetting Approach and Lessons Learned.

2017-01-01

Natural language processing (NLP) holds the promise of effectively analyzing patient record data to reduce cognitive load on physicians and clinicians in patient care, clinical research, and hospital operations management. A critical need in developing such methods is the "ground truth" dataset needed for training and testing the algorithms. Beyond localizable, relatively simple tasks, ground truth creation is a significant challenge because medical experts, just as physicians in patient care, have to assimilate vast amounts of data in EHR systems. To mitigate potential inaccuracies of the cognitive challenges, we present an iterative vetting approach for creating the ground truth for complex NLP tasks. In this paper, we present the methodology, and report on its use for an automated problem list generation task, its effect on the ground truth quality and system accuracy, and lessons learned from the effort.

Humanity has emerged as a major force in the operation of the biosphere, with a significant imprint on the Earth System, challenging social-ecological resilience. This new situation calls for a fundamental shift in perspectives, world views, and institutions. Human development and progress must be reconnected to the capacity of the biosphere and essential ecosystem services to be sustained. Governance challenges include a highly interconnected and faster world, cascading social-ecological interactions and planetary boundaries that create vulnerabilities but also opportunities for social-ecological change and transformation. Tipping points and thresholds highlight the importance of understanding and managing resilience. New modes of flexible governance are emerging. A central challenge is to reconnect these efforts to the changing preconditions for societal development as active stewards of the Earth System. We suggest that the Millennium Development Goals need to be reframed in such a planetary stewardship context combined with a call for a new social contract on global sustainability. The ongoing mind shift in human relations with Earth and its boundaries provides exciting opportunities for societal development in collaboration with the biosphere--a global sustainability agenda for humanity.

Collaborations in astronomy and astrophysics are faced with numerous cyber-infrastructure challenges, such as large data sets, the need to combine heterogeneous data sets, and the challenge to effectively collaborate on those large, heterogeneous data sets with significant processing requirements and complex science software tools. The cyberhubs system is an easy-to-deploy package for small- to medium-sized collaborations based on the Jupyter and Docker technology, which allows web-browser-enabled, remote, interactive analytic access to shared data. It offers an initial step to address these challenges. The features and deployment steps of the system are described, as well as the requirements collection through an account of the different approaches to data structuring, handling, and available analytic tools for the NuGrid and PPMstar collaborations. NuGrid is an international collaboration that creates stellar evolution and explosion physics and nucleosynthesis simulation data. The PPMstar collaboration performs large-scale 3D stellar hydrodynamics simulations of interior convection in the late phases of stellar evolution. Examples of science that is currently performed on cyberhubs, in the areas of 3D stellar hydrodynamic simulations, stellar evolution and nucleosynthesis, and Galactic chemical evolution, are presented.

The United States ranking among the world in science, technology, engineering, and mathematics (STEM) education is decreasing. To counteract this problem NASA has made it part of its mission to promote STEM education among the nation s youth. Mockups can serve as a great tool when promoting STEM education in America. The Orion Cockpit Working Group has created a new program called Students Shaping America s Next Space Craft (SSANS) to outfit the Medium Fidelity Orion Mockup. SSANS will challenge the students to come up with unique designs to represent the flight design hardware. There are two main types of project packages created by SSANS, those for high school students and those for university students. The high school projects will challenge wood shop, metal shop and pre-engineering classes. The university projects are created mainly for senior design projects and will require the students to perform finite element analysis. These projects will also challenge the undergraduate students in material selection and safety requirements. The SSANS program will help NASA in its mission to promote STEM education, and will help to shape our nations youth into the next generation of STEM leaders.

Creating an arsenal of Adeno-associated virus (AAV) gene delivery stealth vehicles.

PubMed

Smith, J Kennon; Agbandje-McKenna, Mavis

2018-05-01

The Adeno-associated virus (AAV) gene delivery system is ushering in a new and exciting era in the United States; following the first approved gene therapy (Glybera) in Europe, the FDA has approved a second therapy, Luxturna [1]. However, challenges to this system remain. In viral gene therapy, the surface of the capsid is an important determinant of tissue tropism, impacts gene transfer efficiency, and is targeted by the human immune system. Preexisting immunity is a significant challenge to this approach, and the ability to visualize areas of antibody binding ("footprints") can inform efforts to improve the efficacy of viral vectors. Atomic resolution, smaller proteins, and asymmetric structures are the goals to attain in cryo-electron microscopy and image reconstruction (cryo-EM) as of late. The versatility of the technique and the ability to vitrify a wide range of heterogeneous molecules in solution allow structural biologists to characterize a variety of protein-DNA and protein-protein interactions at lower resolution. Cryo-EM has served as an important means to study key surface areas of the AAV gene delivery vehicle-specifically, those involved with binding neutralizing antibodies (NAbs) [2-4]. This method offers a unique opportunity for visualizing antibody binding "hotspots" on the surface of these and other viral vectors. When combined with mutagenesis, one can eliminate these hotspots to create viral vectors with the ability to avoid preexisting host immune recognition during gene delivery and genetic defect correction in disease treatment. Here, we discuss the use of structure-guided site-directed mutagenesis and directed evolution to create "stealth" AAV vectors with modified surface amino acid sequences that allow NAb avoidance while maintaining natural capsid functions or gaining desired novel tropisms.

Near Real-time Scientific Data Analysis and Visualization with the ArcGIS Platform

NASA Astrophysics Data System (ADS)

Shrestha, S. R.; Viswambharan, V.; Doshi, A.

2017-12-01

Scientific multidimensional data are generated from a variety of sources and platforms. These datasets are mostly produced by earth observation and/or modeling systems. Agencies like NASA, NOAA, USGS, and ESA produce large volumes of near real-time observation, forecast, and historical data that drives fundamental research and its applications in larger aspects of humanity from basic decision making to disaster response. A common big data challenge for organizations working with multidimensional scientific data and imagery collections is the time and resources required to manage and process such large volumes and varieties of data. The challenge of adopting data driven real-time visualization and analysis, as well as the need to share these large datasets, workflows, and information products to wider and more diverse communities, brings an opportunity to use the ArcGIS platform to handle such demand. In recent years, a significant effort has put in expanding the capabilities of ArcGIS to support multidimensional scientific data across the platform. New capabilities in ArcGIS to support scientific data management, processing, and analysis as well as creating information products from large volumes of data using the image server technology are becoming widely used in earth science and across other domains. We will discuss and share the challenges associated with big data by the geospatial science community and how we have addressed these challenges in the ArcGIS platform. We will share few use cases, such as NOAA High Resolution Refresh Radar (HRRR) data, that demonstrate how we access large collections of near real-time data (that are stored on-premise or on the cloud), disseminate them dynamically, process and analyze them on-the-fly, and serve them to a variety of geospatial applications. We will also share how on-the-fly processing using raster functions capabilities, can be extended to create persisted data and information products using raster analytics capabilities that exploit distributed computing in an enterprise environment.

Creating new growth platforms.

PubMed

Laurie, Donald L; Doz, Yves L; Sheer, Claude P

2006-05-01

Sooner or later, most companies can't attain the growth rates expected by their boards and CEOs and demanded by investors. To some extent, such businesses are victims of their own successes. Many were able to sustain high growth rates for a long time because they were in high-growth industries. But once those industries slowed down, the businesses could no longer deliver the performance that investors had come to take for granted. Often, companies have resorted to acquisition, though this strategy has a discouraging track record. Over time, 65% of acquisitions destroy more value than they create. So where does real growth come from? For the past 12 years, the authors have been researching and advising companies on this issue. With the support of researchers at Harvard Business School and Insead, they instituted a project titled "The CEO Agenda and Growth". They identified and approached 24 companies that had achieved significant organic growth and interviewed their CEOs, chief strategists, heads of R&D, CFOs, and top-line managers. They asked, "Where does your growth come from?" and found a consistent pattern in the answers. All the businesses grew by creating new growth platforms (NGPs) on which they could build families of products and services and extend their capabilities into multiple new domains. Identifying NGP opportunities calls for executives to challenge conventional wisdom. In all the companies studied, top management believed that NGP innovation differed significantly from traditional product or service innovation. They had independent, senior-level units with a standing responsibility to create NGPs, and their CEOs spent as much as 50% of their time working with these units. The payoff has been spectacular and lasting. For example, from 1985 to 2004, the medical devices company Medtronic grew revenues at 18% per year, earnings at 20%, and market capitalization at 30%.

Web Based Homework for CAPA in General Education Astronomy Courses

NASA Astrophysics Data System (ADS)

Robertson, T. H.

2002-12-01

Qualitative questions in astronomy have been developed to operate under the CAPA web-based homework system. Multiple versions of similar questions and software randomization are used to create different homework sets for each student. The questions are grouped by concept and subject to create more challenging activities from relatively simple questions. These questions have been used for three semesters in five sections of ASTRO 100 which enrolled a total of 500 students over the past two years. Student surveys consistently indicate that they like the system and believe that it helps them to learn. Cognitive measures in the form of exam and course grades do not demonstrate statistically significant improvement in sections which have used the new homework system. This is due in part to a conscious effort to create exam questions which focus on content understanding and not memorization and the persistent student habit of studying for exams by memorizing homework. Differences have been identified between female and male students in terms of completion rates and performance on homework, quiz and exam scores. This work was supported in part by funding from the George and Frances Ball Fund for Academic Excellence and the 21st Century Fund for Faculty Development.

Multi-material 3D Models for Temporal Bone Surgical Simulation.

2015-07-01

A simulated, multicolor, multi-material temporal bone model can be created using 3-dimensional (3D) printing that will prove both safe and beneficial in training for actual temporal bone surgical cases. As the process of additive manufacturing, or 3D printing, has become more practical and affordable, a number of applications for the technology in the field of Otolaryngology-Head and Neck Surgery have been considered. One area of promise is temporal bone surgical simulation. Three-dimensional representations of human temporal bones were created from temporal bone computed tomography (CT) scans using biomedical image processing software. Multi-material models were then printed and dissected in a temporal bone laboratory by attending and resident otolaryngologists. A 5-point Likert scale was used to grade the models for their anatomical accuracy and suitability as a simulation of cadaveric and operative temporal bone drilling. The models produced for this study demonstrate significant anatomic detail and a likeness to human cadaver specimens for drilling and dissection. Simulated temporal bones created by this process have potential benefit in surgical training, preoperative simulation for challenging otologic cases, and the standardized testing of temporal bone surgical skills. © The Author(s) 2015.

M-and-C Domain Map Maker: an environment complimenting MDE with M-and-C knowledge and ensuring solution completeness

NASA Astrophysics Data System (ADS)

Patwari, Puneet; Choudhury, Subhrojyoti R.; Banerjee, Amar; Swaminathan, N.; Pandey, Shreya

2016-07-01

Model Driven Engineering (MDE) as a key driver to reduce development cost of M&C systems is beginning to find acceptance across scientific instruments such as Radio Telescopes and Nuclear Reactors. Such projects are adopting it to reduce time to integrate, test and simulate their individual controllers and increase reusability and traceability in the process. The creation and maintenance of models is still a significant challenge to realizing MDE benefits. Creating domain-specific modelling environments reduces the barriers, and we have been working along these lines, creating a domain-specific language and environment based on an M&C knowledge model. However, large projects involve several such domains, and there is still a need to interconnect the domain models, in order to ensure modelling completeness. This paper presents a knowledge-centric approach to doing that, by creating a generic system model that underlies the individual domain knowledge models. We present our vision for M&C Domain Map Maker, a set of processes and tools that enables explication of domain knowledge in terms of domain models with mutual consistency relationships to aid MDE.

Ethical challenges in fetal surgery.

PubMed

Smajdor, Anna

2011-02-01

Fetal surgery has been practised for some decades now. However, it remains a highly complex area, both medically and ethically. This paper shows how the routine use of ultrasound has been a catalyst for fetal surgery, in creating new needs and new incentives for intervention. Some of the needs met by fetal surgery are those of parents and clinicians who experience stress while waiting for the birth of a fetus with known anomalies. The paper suggests that the role of technology and visualisation techniques in creating and meeting such new needs is ethically problematic. It then addresses the idea that fetal surgery should be restricted to interventions that are life-saving for the fetus, arguing that this restriction is unduly paternalistic. Fetal surgery poses challenges for an autonomy-based system of ethics. However, it is risky to circumvent these challenges by restricting the choices open to pregnant women, even when these choices appear excessively altruistic.

Plain language: a strategic response to the health literacy challenge.

PubMed

Stableford, Sue; Mettger, Wendy

2007-01-01

Low health literacy is a major challenge confronting American and international health organizations. Research in the past decade has documented the prevalence of limited literacy and limited health literacy skills among adults worldwide. This creates a major policy challenge: how to create text-based health information - a common method of health communication - that is accessible to the public. Plain language is a logical, flexible response. While touted by American, Canadian, and European health policy makers, adoption and promotion of plain language standards and skills in health-focused organizations have lagged. Most text-based health information continues to be too hard for most adults to read. Barriers to more rapid diffusion of plain language are reflected in a set of myths perpetuated by critics. These myths are identified and refuted. While plain language is only one of many broad-based solutions needed to address low health literacy, the benefits to everyone demand increased use by health organizations.

Geoscience Challenges of a State-by-state Adoption or Adaptation of the NGSS

NASA Astrophysics Data System (ADS)

Wysession, M. E.

2016-12-01

For the geosciences, the Next Generation Science Standards (NGSS) contain the largest shift in K-12 education to have happened in our lifetimes, but its adoption is playing our very differently in different states. Because it is illegal to have a national curriculum, the NGSS intentionally avoided providing a curriculum but rather a set of performance expectations that each state (or district or school) could use in its own way to construct assessments and curricula. The result is that although more than 80% of schools in the U.S. are in the process of revising their curricula to align with the NGSS, this is happening in a different way in each state (or district or school). Instead of having a single target for curriculum developers to aim for, the result is to actually create a greater diversity of pedagogic platforms across the U.S. schools than there was before the NGSS were released. Some states (Alaska, North Dakota, Texas, Virginia) stated at the outset that they would not be adopting any version of the NGSS at all. So far seventeen states (and D.C.) have adopted the NGSS verbatim, but they are still each developing their curricula in their own way. In fossil-fuel-concentrated communities, such as Wyoming, Oklahoma, and West Virginia, the strong presence of the topics of climate and climate change in the NGSS have created complications for its adoption. States that still only require two years of high school science for all students, so the addition of a year of Earth and Space Science is creating legislative challenges. There is a general lack of trained and accredited high school geoscience teachers in nearly all states (with a few notable exceptions, such as New York), so the preparation and training of high school geoscience teachers is a significant nationwide concern. There are also large variations in the development of assessment materials, pre-service training, and updating certification programs. Progress is definitely being made, but the NGSS is looking like a patchwork quilt, with no two states' pieces the same, and this is posing great challenges for curriculum developers.

Why does it matter how we regulate the use of human body parts?

PubMed

Goold, Imogen

2014-01-01

Human tissue and body parts have been used in one way or another for millennia. They have been preserved and displayed, both in museums and public shows. Real human hair is used for wigs, while some artists even use human tissue in their works. Blood, bone marrow, whole organs and a host of other structures and human substances are all transplanted into living persons to treat illness. New life can be created from gametes through in vitro fertilisation (IVF), while the creation of cell lines keeps tissue alive indefinitely. These uses create significant challenges for the legal system in the UK. The major challenge for the law is to balance the competing demands of those groups who have vested interests in human tissue-researchers, medical practitioners, patients, families, the community and the police, among many others. It must provide sufficient control to users of tissue, but also take account of the fact that our bodies hold psychological importance for us while we live and, after we die, for those we leave behind. To some degree the law has been successful, but we still lack a comprehensive, coherent approach to the regulation of human tissue. Partially as a reaction to this lack of a comprehensive approach, some commentators have turned to applying the concept of property to human tissue means to achieve regulatory outcomes they support.

Grand challenges to create new front metallization techniques in photovoltaic focus considerable attention on laser-induced forward transfer (LIFT) approach. This alternative method aims to overcome the limitations of the well-established and mature screen-printing (SP) technique. Such limitations are for instance restrictions in the grid pattern design, high-temperature steps, and limited aspect ratio of the line contact (Poulain et al. in Appl Surf Sci 257:5241-5244, 2011). Although different new front contact metallization concepts have been studied, most of them require a second print step to increase the volume of the contact (Gao et al. in Proceedings of 25th EU PVSEC conference, 2010; Beaucarne and Schubert in Energy Proc 67:2-12, 2015; Lossen and Matusovsky in Energy Proc 67:156-162, 2015; Green in Phys E 14:65-70, 2002; Lennon et al. in Prog Photovolt Res Appl V21:1454-1468, 2012). As a result, it is desirable to find innovative metallization techniques to improve the cell efficiency without significantly increasing the cost. Although many challenges remain before to obtain high-quality, robust, and high-performance LIFT contact formation, it required a fully theoretical and experimental assessment. This paper presents the results of a study of the LIFT technique in picosecond regime and thick silver pastes to create high-quality conductive lines for photovoltaic applications.

Socio-Cultural Impacts in the Formation of Urban Village

NASA Astrophysics Data System (ADS)

Marpaung, B. O. Y.

2017-03-01

In Indonesia, a group of village people tends to move from one place to another and develops a living space to create a settlement. This research is conducted by taking an example of a particular ethnic group that leaves the forestry area to a new place in the city. After some time, this group of people creates a similar or adapted socio-cultural system adapted from their origin place. The purpose of this research is to examine the socio-cultural aspects that significantly influence the emergence of urban village. This influence is interpreted as social and cultural relations with the establishment of space and significance of urban village. By focusing on this issue, this research will trace the process of how a new and unplanned settlement could emerge. The process and elements are indispensable from social and cultural factors. Essentially, the shape of bulit space is a non-physical manifestation of local people, which is established from time to time. In this case, the research’s challenge lies on the circumstance in Indonesia where society and culture influence the emergence of urban village. Physical appearance can be identified as a tipology of settlement and morphology of urban village.

Enabling all young Australians to grow up safe, happy, healthy and resilient: a Collaboration for Young People, Technology and Wellbeing.

PubMed

2011-07-01

This paper describes a framework for a multi-disciplinary collaboration to investigate the role of technology for improving young Australians' mental health and wellbeing. The poor mental health of young Australians poses a significant challenge to Australia's future. Half of all Australians will experience a mental health difficulty in their lifetime and 75% of mental illness has its onset before age 25. Cross-sectoral collaboration is critical for meeting this challenge. In order to establish a world-first multi-partner collaboration, leading researchers and institutes, commercial, non-profit and end-user organization and young people were identified and invited to participate. Together we have developed an international research framework that explores the role of technologies in young people's lives, their potential and how this can be harnessed to address challenges facing young people. This research framework will: (i) conduct empirical research that tests the utility of technology across mental health promotion, prevention, early intervention and treatment and, (ii) translate existing and new knowledge into products and services that help create a generation of safe, happy, healthy and resilient young people. Research undertaken by the Collaboration will be the most comprehensive investigation of technologies' potential to improve the wellbeing of young people ever conducted, leading to significant benefits for Australian young people and their mental health.

Science Planning and Orbit Classification for Solar Probe Plus

Kusterer, M. B.; Fox, N. J.; Rodgers, D. J.; Turner, F. S.

2016-12-01

There are a number of challenges for the Science Planning Team (SPT) of the Solar Probe Plus (SPP) Mission. Since SPP is using a decoupled payload operations approach, tight coordination between the mission operations and payload teams will be required. The payload teams must manage the volume of data that they write to the spacecraft solid-state recorders (SSR) for their individual instruments for downlink to the ground. Making this process more difficult, the geometry of the celestial bodies and the spacecraft during some of the SPP mission orbits cause limited uplink and downlink opportunities. The payload teams will also be required to coordinate power on opportunities, command uplink opportunities, and data transfers from instrument memory to the spacecraft SSR with the operation team. The SPT also intend to coordinate observations with other spacecraft and ground based systems. To solve these challenges, detailed orbit activity planning is required in advance for each orbit. An orbit planning process is being created to facilitate the coordination of spacecraft and payload activities for each orbit. An interactive Science Planning Tool is being designed to integrate the payload data volume and priority allocations, spacecraft ephemeris, attitude, downlink and uplink schedules, spacecraft and payload activities, and other spacecraft ephemeris. It will be used during science planning to select the instrument data priorities and data volumes that satisfy the orbit data volume constraints and power on, command uplink and data transfer time periods. To aid in the initial stages of science planning we have created an orbit classification scheme based on downlink availability and significant science events. Different types of challenges arise in the management of science data driven by orbital geometry and operational constraints, and this scheme attempts to identify the patterns that emerge.

Native articular cartilage has limited capacity to repair itself from focal defects or osteoarthritis. Tissue engineering has provided a promising biological treatment strategy that is currently being evaluated in clinical trials. However, current approaches in translating these techniques to developing large engineered tissues remains a significant challenge. In this study, we present a method for developing large-scale engineered cartilage surfaces through modular fabrication. Modular Engineered Tissue Surfaces (METS) uses the well-known, but largely under-utilized self-adhesion properties of de novo tissue to create large scaffolds with nutrient channels. Compressive mechanical properties were evaluated throughout METS specimens, and the tensile mechanical strength of the bonds between attached constructs was evaluated over time. Raman spectroscopy, biochemical assays, and histology were performed to investigate matrix distribution. Results showed that by Day 14, stable connections had formed between the constructs in the METS samples. By Day 21, bonds were robust enough to form a rigid sheet and continued to increase in size and strength over time. Compressive mechanical properties and glycosaminoglycan (GAG) content of METS and individual constructs increased significantly over time. The METS technique builds on established tissue engineering accomplishments of developing constructs with GAG composition and compressive properties approaching native cartilage. This study demonstrated that modular fabrication is a viable technique for creating large-scale engineered cartilage, which can be broadly applied to many tissue engineering applications and construct geometries.

Challenges in the nurse's role in rehabilitation contexts.

Christiansen, Bjørg; Feiring, Marte

2017-10-01

To shed light on how nurses perceive particular challenges that they experience in encounters with patients in rehabilitation wards. Rehabilitation is a tailor-made process that allows someone with impairment to live well. Many rehabilitation institutions embrace strong beliefs in patient participation as well as awareness of and listening to the needs and wishes of patients. To our knowledge, few studies have investigated the challenges encountered by nurses from patients in rehabilitation contexts and how these challenges might influence their roles as nurses. This study has a qualitative design that is based on three focus group interviews with nurses working in three rehabilitation wards. A convenience sample of 15 nurses, five from each ward, was recruited to participate in focus group interviews. The participants worked in wards for patients suffering mainly from stroke and head injuries. The analysis is inspired by hermeneutic principles to explore the participants' challenges in their role in rehabilitation contexts. Data analyses identified three main themes surrounding the challenges experienced by nurses: (1) Adjusting patients' and next of kin's expectations, (2) Tailoring support and information, (3) Recognising patients' knowledge. Our results from the three rehabilitation wards indicate that nurses display various educative strategies. There is, however, a need for further empirical work into how knowledgeable patients and next of kin create new challenges with implications for the nurse's role within rehabilitation contexts. The study highlights the educative aspects of the nurse's role in relation to patients and next of kin on rehabilitation wards as significant contributors to recovery processes. © 2016 John Wiley & Sons Ltd.

The significance of ethics reflection groups in mental health care: a focus group study among health care professionals.

Professionals within the mental health services face many ethical dilemmas and challenging situations regarding the use of coercion. The purpose of this study was to evaluate the significance of participating in systematic ethics reflection groups focusing on ethical challenges related to coercion. In 2013 and 2014, 20 focus group interviews with 127 participants were conducted. The interviews were tape recorded and transcribed verbatim. The analysis is inspired by the concept of 'bricolage' which means our approach was inductive. Most participants report positive experiences with participating in ethics reflection groups: A systematic and well-structured approach to discuss ethical challenges, increased consciousness of formal and informal coercion, a possibility to challenge problematic concepts, attitudes and practices, improved professional competence and confidence, greater trust within the team, more constructive disagreement and room for internal critique, less judgmental reactions and more reasoned approaches, and identification of potential for improvement and alternative courses of action. On several wards, the participation of psychiatrists and psychologists in the reflection groups was missing. The impact of the perceived lack of safety in reflection groups should not be underestimated. Sometimes the method for ethics reflection was utilised in a rigid way. Direct involvement of patients and family was missing. This focus group study indicates the potential of ethics reflection groups to create a moral space in the workplace that promotes critical, reflective and collaborative moral deliberations. Future research, with other designs and methodologies, is needed to further investigate the impact of ethics reflection groups on improving health care practices.

Creating an "Education Shark Tank" to Encourage and Support Educational Scholarship and Innovation.

Cofrancesco, Joseph; Wright, Scott M; Vohr, Eric; Ziegelstein, Roy C

2017-11-01

Creating and supporting opportunities for innovation that showcase and reward creativity in medical and biomedical education is critically important for academic institutions, learners, and faculty. In 2014, the Institute for Excellence in Education at Johns Hopkins University School of Medicine created a small grant program called Education Shark Tank, in which two to five finalist teams present their proposals on innovative initiatives to improve education to four or five senior educator "sharks" at an educational conference, with an audience. The sharks then "grill" the presenters, considering which if any to fund, focusing on the rationale, feasibility, appropriateness of the outcome measures, evaluation and assessment plan, and proposed method of dissemination. They also make suggestions that challenge the presenters to assess and improve their designs. In the program's first year (2014), funds were divided equally between two projects, both of which were successfully completed and one of which led to a journal publication; this led to increased funding for the program in 2015. Participants have called Education Shark Tank a "challenging and rewarding experience." Education Shark Tank can facilitate educational innovation and scholarship via engaging and challenging interactions between grant applicants and reviewers in a public venue. The authors plan to conduct a five-year survey (after 2018) of all Education Shark Tank finalists to determine the success and challenges the funded projects have had, what scholarly dissemination has occurred, whether nonfunded projects were able to move forward, and the value of the feedback and mentoring received.

From RHIC to LHC: Lessons on the QGP

NASA Astrophysics Data System (ADS)

Heinz, Ulrich

2011-10-01

Recent data from heavy-ion collisions at RHIC and LHC, together with significant advances in theory, have allowed us to make significant first steps in proceeding from a qualitative understanding of high energy collision dynamics to a quantitative characterization of the transport properties of the hot and dense QCD matter created in these collisions. The almost perfectly liquid nature of the Quark-Gluon Plasma (QGP) created at RHIC has recently also been confirmed at the much higher LHC energies, and we can now constrain the specific QGP shear viscosity (η / s) QGP to within a factor of 2.5 of its conjectured lower quantum bound. Viscous hydrodynamics, coupled to a microscopic hadron cascade at late times, has proven to be an extremely successful and highly predictive model for the QGP evolution at RHIC and LHC. The experimental discovery of higher order harmonic flow coefficients and their theoretically predicted differential sensitivity to shear viscosity promises additional gains in precision by about a factor 5 in (η / s) QGP for the very near future. The observed modification of jets and suppression of high-pT hadrons confirms the picture of the QGP as a strongly coupled colored liquid, and recent LHC data yield strong constraints on parton energy loss models, putting significant strain on some theoretical approaches, tuned to RHIC data, that are based on leading-order perturbative QCD. Thermal photon radiation provides important cross-checks on the early stages of dynamical evolution models and constrains the initial QGP temperature, but the recently measured strong photon elliptic flow challenges our present understanding of photon emission rates in the hadronic phase. Recent progress in developing a complete theoretical model for all stages of the QGP fireball expansion, from strong fluctuating gluon fields at its beginning to final hadronic freeze-out, and remaining challenges will be discussed.

Pain intensity and duration can be enhanced by prior challenge: Initial evidence suggestive of a role of microglial priming

2010-01-01

Activation of spinal microglia and consequent release of pro-inflammatory mediators facilitate pain. Under certain conditions, responses of activated microglia can become enhanced. Enhanced microglial production of pro-inflammatory products may result from priming (sensitization), similar to macrophage priming. We hypothesized that if spinal microglia were primed by an initial inflammatory challenge, subsequent challenges may create enhanced pain. Here, we used a "two-hit" paradigm using two successive challenges, which affect overlapping populations of spinal microglia, presented two weeks apart. Mechanical allodynia and/or activation of spinal glia were assessed. Initially, laparotomy preceded systemic lipopolysaccharide (LPS). Prior laparotomy caused prolonged microglial (not astrocyte) activation plus enhanced LPS-induced allodynia. In this “two-hit” paradigm, minocycline, a microglial activation inhibitor, significantly reduced later exaggerated pain induced by prior surgery when minocycline was administered intrathecally for 5 days starting either at the time of surgery or 5 days before LPS administration. To test generality of the priming effect, subcutaneous formalin preceded intrathecal HIV-1 gp120, which activates spinal microglia and causes robust allodynia. Prior formalin enhanced intrathecal gp120-induced allodynia, suggesting that microglial priming is not limited to laparotomy and again supporting a spinal site of action. Therefore, spinal microglial priming may increase vulnerability to pain enhancement. PMID:20434956

The Challenges of Leadership.

PubMed

Myrtle, Robert C

Perhaps in no other period in recent times have the challenges leaders face been so profound. In these times of uncertainty and turbulence, we look to leaders who create a sense of purpose, who generate feelings of trust and optimism, and who tap the passion, talent, and efforts of those so essential to the success of the organization and of the people it serves. Our research suggests that becoming the leader whom people look to and admire requires an active commitment to responding to 5 essential leadership challenges. These are (1) creating a sense of purpose, (2) devising means for aligning the actions of the followers with that sense of purpose, (3) establishing a context that enables others to behave in a way that is consistent with the vision and values of the organization, (4) ensuring that the work that is done provides meaning to those engaging in the work activities, and (5) adding to the sum of everyone's knowledge through learning through reflective actions. In this article, we describe these challenges and offer suggestions that you can take to become a more effective and respected leader.

On leadership organizational intelligence/organizational stupidity: the leader's challenge.

PubMed

Kerfoot, Karlene

2003-01-01

Creating organizations with a high IQ or creating organizations without the necessary intelligence guarantees success or failure of the organization. Without structures such as shared leadership and other forms of participative management, the organization or unit cannot access and use the available information and wisdom in the organization. When nurses and other health care professionals do not feel like they have a shared stake and do not feel like citizens of the organization, they lack passion for the organization's work. When nurses feel a sense of share ownnership and autonomy for the clinical practice, terrific outcomes are achieved. Leaders must accept the challenge to build the infrastructure that leads to excellence in organizational IQ.

Strategies are needed to ensure that the U.S. Government meets its goals for improving the health of the nation (e.g., Healthy People 2020). To date, progress toward these goals has been undermined by a set of discernible challenges: People lack sufficient motivation, they frequently fail to translate healthy intentions into action, their efforts are undermined by the persistence of prior unhealthy habits, and they have considerable difficulty maintaining new healthy patterns of behavior. Guided by advances in psychological science, we provide innovative, evidence-based policies that address each of these challenges and, if implemented, will enhance people's ability to create and maintain healthy behavioral practices. © The Author(s) 2015.

The assembly, collapse and restoration of food webs

Dobson, Andy; Allesina, Stefano; Lafferty, Kevin; Pascual, Mercedes

2009-01-01

Darwin chose the metaphor of a 'tangled bank' to conclude the 'Origin of species'. Two centuries after Darwin's birth, we are still untangling the complex ecological networks he has pondered. In particular, studies of food webs provide important insights into how natural ecosystems function (Pascual & Dunne 2005). Although the nonlinear interactions between many species creates challenges of scale, resolution of data and significant computational constraints, the last 10 years have seen significant advances built on the earlier classic studies of Cohen, May, Pimm, Polis, Lawton and Yodzis (May 1974; Cohen 1978; Pimm 1982; Briand & Cohen 1984, 1987; Yodzis 1989; Cohen et al. 1990; Pimm et al. 1991; Yodzis & Innes 1992; Yodzis 1998). These gains stem from advances in computing power and the collation of more comprehensive data from a broader array of empirical food webs.

Mixed region reactors for in situ treatment of DNAPL contaminated low permeability media

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

West, O.R.; Siegrist, R.L.

1996-08-01

Fine-textured soils and sediments contaminated by dense non-aqueous phase liquids (DNAPLs) present a significant environmental restoration challenge. An emerging approach to rapid in situ treatment within low permeability media involves the use of soil mixing to create mixed region reactors wherein biological or physical/chemical treatment processes can be employed. In cohesive soils, mixing breaks up the original soil structure and produces soil aggregates or clods separated by interaggregate void spaces. These void spaces create preferential flow paths for more efficient extraction of contaminants from the soil matrix or more rapid diffusion of treatment agents into the soil aggregates. This enhancementmore » technology has been most successfully used with vapor stripping. However, other technologies can also be coupled with soil mixing including chemical degradation, biodegradation and solidification. The application of this technology to DNAPL-contaminated low permeability media appears promising but requires further experiments and models that can simulate the movement of DNAPLs in mixed regions. 11 refs., 6 figs.« less

Nanoscale optical positioning of single quantum dots for bright and pure single-photon emission

PubMed Central

Sapienza, Luca; Davanço, Marcelo; Badolato, Antonio; Srinivasan, Kartik

2015-01-01

Self-assembled, epitaxially grown InAs/GaAs quantum dots (QDs) are promising semiconductor quantum emitters that can be integrated on a chip for a variety of photonic quantum information science applications. However, self-assembled growth results in an essentially random in-plane spatial distribution of QDs, presenting a challenge in creating devices that exploit the strong interaction of single QDs with highly confined optical modes. Here, we present a photoluminescence imaging approach for locating single QDs with respect to alignment features with an average position uncertainty <30 nm (<10 nm when using a solid-immersion lens), which represents an enabling technology for the creation of optimized single QD devices. To that end, we create QD single-photon sources, based on a circular Bragg grating geometry, that simultaneously exhibit high collection efficiency (48%±5% into a 0.4 numerical aperture lens, close to the theoretically predicted value of 50%), low multiphoton probability (g(2)(0) <1%), and a significant Purcell enhancement factor (≈3).

2018-02-01

Hypoglycemia poses significant risk to inpatients. Nursing management of hypoglycemia is a challenge, despite established best practice guidelines. Social media is an effective tool for sharing information and could overcome barriers to clinical education at a multicenter hospital. The purpose of this quality improvement intervention was to create and disseminate social media posts about best practices in hypoglycemia management. An unmatched pre-and post-survey assessed nursing knowledge of hypoglycemia management. Social media posts were created to visually outline the steps for hypoglycemia management over 2 weeks, across a nursing social media platform. We assessed the reach of the posts via Facebook and a survey. The posts reached 2962 users during the first week, and 1491 users the second week. A social media intervention can have a substantial reach and distribute information across a multicenter hospital. Additional study is needed to determine what factors could support an increase in nursing knowledge through a social media campaign.

The globalization of the nursing workforce: Pulling the pieces together.

PubMed

Jones, Cheryl B; Sherwood, Gwen D

2014-01-01

The "globalization" of health care creates an increasingly interconnected workforce spanning international boundaries, systems, structures, and processes to provide care to and improve the health of peoples around the world. Because nurses comprise a large sector of the global health workforce, they are called upon to provide a significant portion of nursing and health care and thus play an integral role in the global health care economy. To meet global health care needs, nurses often move within and among countries, creating challenges and opportunities for the profession, health care organizations, communities, and nations. Researchers, policy makers, and industry and academic leaders must, in turn, grapple with the impacts of globalization on the nursing and health care workforce. Through this special issue, several key areas for discussion are raised. Although far from exhaustive, our intent is to expand and stimulate intra- and interprofessional conversations raising awareness of the issues, uncover unanticipated consequences, and offer solutions for shaping the nursing and health care workforce of the future.

Globalization and advances in information and communication technologies: the impact on nursing and health.

PubMed

Abbott, Patricia A; Coenen, Amy

2008-01-01

Globalization and information and communication technology (ICT) continue to change us and the world we live in. Nursing stands at an opportunity intersection where challenging global health issues, an international workforce shortage, and massive growth of ICT combine to create a very unique space for nursing leadership and nursing intervention. Learning from prior successes in the field can assist nurse leaders in planning and advancing strategies for global health using ICT. Attention to lessons learned will assist in combating the technological apartheid that is already present in many areas of the globe and will highlight opportunities for innovative applications in health. ICT has opened new channels of communication, creating the beginnings of a global information society that will facilitate access to isolated areas where health needs are extreme and where nursing can contribute significantly to the achievement of "Health for All." The purpose of this article is to discuss the relationships between globalization, health, and ICT, and to illuminate opportunities for nursing in this flattening and increasingly interconnected world.

Active learning machine learns to create new quantum experiments.

Melnikov, Alexey A; Poulsen Nautrup, Hendrik; Krenn, Mario; Dunjko, Vedran; Tiersch, Markus; Zeilinger, Anton; Briegel, Hans J

2018-02-06

How useful can machine learning be in a quantum laboratory? Here we raise the question of the potential of intelligent machines in the context of scientific research. A major motivation for the present work is the unknown reachability of various entanglement classes in quantum experiments. We investigate this question by using the projective simulation model, a physics-oriented approach to artificial intelligence. In our approach, the projective simulation system is challenged to design complex photonic quantum experiments that produce high-dimensional entangled multiphoton states, which are of high interest in modern quantum experiments. The artificial intelligence system learns to create a variety of entangled states and improves the efficiency of their realization. In the process, the system autonomously (re)discovers experimental techniques which are only now becoming standard in modern quantum optical experiments-a trait which was not explicitly demanded from the system but emerged through the process of learning. Such features highlight the possibility that machines could have a significantly more creative role in future research.

Sparse synthetic aperture with Fresnel elements (S-SAFE) using digital incoherent holograms

Kashter, Yuval; Rivenson, Yair; Stern, Adrian; Rosen, Joseph

2015-01-01

Creating a large-scale synthetic aperture makes it possible to break the resolution boundaries dictated by the wave nature of light of common optical systems. However, their implementation is challenging, since the generation of a large size continuous mosaic synthetic aperture composed of many patterns is complicated in terms of both phase matching and time-multiplexing duration. In this study we present an advanced configuration for an incoherent holographic imaging system with super resolution qualities that creates a partial synthetic aperture. The new system, termed sparse synthetic aperture with Fresnel elements (S-SAFE), enables significantly decreasing the number of the recorded elements, and it is free from positional constrains on their location. Additionally, in order to obtain the best image quality we propose an optimal mosaicking structure derived on the basis of physical and numerical considerations, and introduce three reconstruction approaches which are compared and discussed. The super-resolution capabilities of the proposed scheme and its limitations are analyzed, numerically simulated and experimentally demonstrated. PMID:26367947

Agilent Laboratories looks to the future to identify, invest and enable technologies and applications that will nurture the world’s people, environment and economies, and help ensure Agilent’s continuing leadership. Following a brief introduction to Agilent Technologies and Agilent Laboratories, Solomon will discuss how innovation and long-term R&D are transcending traditional boundaries. Focusing on the life sciences industry, she will discuss current trends in R&D and the importance of measurement in advancing the industry. She will describe some of the challenges that are disrupting the pharmaceutical industry where significant and sustained investment in R&D has not translated into large numbers of block-buster therapeutics. Much of this gap results from the profound complexity of biological systems. New discoveries quickly generate new questions, which in turn drive more research and necessitate new business models. Solomon will highlight examples of Agilent’s long-range R&D in life sciences, emphasizing the importance of physics. She’ll conclude with the importance of creating sustainable value with R&D.

Muscle activity and spine load during anterior chain whole body linkage exercises: the body saw, hanging leg raise and walkout from a push-up.

PubMed

McGill, Stuart; Andersen, Jordan; Cannon, Jordan

2015-01-01

This study examined anterior chain whole body linkage exercises, namely the body saw, hanging leg raise and walkout from a push-up. Investigation of these exercises focused on which particular muscles were challenged and the magnitude of the resulting spine load. Fourteen males performed the exercises while muscle activity, external force and 3D body segment motion were recorded. A sophisticated and anatomically detailed 3D model used muscle activity and body segment kinematics to estimate muscle force, and thus sensitivity to each individual's choice of motor control for each task. Gradations of muscle activity and spine load characteristics were observed across tasks. On average, the hanging straight leg raise created approximately 3000 N of spine compression while the body saw created less than 2500 N. The hanging straight leg raise created the highest challenge to the abdominal wall (>130% MVC in rectus abdominis, 88% MVC in external oblique). The body saw resulted in almost 140% MVC activation of the serratus anterior. All other exercises produced substantial abdominal challenge, although the body saw did so in the most spine conserving way. These findings, along with consideration of an individual's injury history, training goals and current fitness level, should assist in exercise choice and programme design.

Using a participatory evaluation design to create an online data collection and monitoring system for New Mexico's Community Health Councils.

Andrews, M L; Sánchez, V; Carrillo, C; Allen-Ananins, B; Cruz, Y B

2014-02-01

We present the collaborative development of a web-based data collection and monitoring plan for thirty-two county councils within New Mexico's health council system. The monitoring plan, a key component in our multiyear participatory statewide evaluation process, was co-developed with the end users: representatives of the health councils. Guided by the Institute of Medicine's Community, Health Improvement Process framework, we first developed a logic model that delineated processes and intermediate systems-level outcomes in council development, planning, and community action. Through the online system, health councils reported data on intermediate outcomes, including policy changes and funds leveraged. The system captured data that were common across the health council system, yet was also flexible so that councils could report their unique accomplishments at the county level. A main benefit of the online system was that it provided the ability to assess intermediate, outcomes across the health council system. Developing the system was not without challenges, including creating processes to ensure participation across a large rural state; creating shared understanding of intermediate outcomes and indicators; and overcoming technological issues. Even through the challenges, however, the benefits of committing to using participatory processes far outweighed the challenges. Copyright © 2013 Elsevier Ltd. All rights reserved.

Trade challenges at the World Trade Organization to national noncommunicable disease prevention policies: A thematic document analysis of trade and health policy space.

PubMed

Barlow, Pepita; Labonte, Ronald; McKee, Martin; Stuckler, David

2018-06-01

It has long been contested that trade rules and agreements are used to dispute regulations aimed at preventing noncommunicable diseases (NCDs). Yet most analyses of trade rules and agreements focus on trade disputes, potentially overlooking how a challenge to a regulation's consistency with trade rules may lead to 'policy or regulatory chill' effects whereby countries delay, alter, or repeal regulations in order to avoid the costs of a dispute. Systematic empirical analysis of this pathway to impact was previously prevented by a dearth of systematically coded data. Here, we analyse a newly created dataset of trade challenges about food, beverage, and tobacco regulations among 122 World Trade Organization (WTO) members from January 1, 1995 to December 31, 2016. We thematically describe the scope and frequency of trade challenges, analyse economic asymmetries between countries raising and defending them, and summarise 4 cases of their possible influence. Between 1995 and 2016, 93 food, beverage, and tobacco regulations were challenged at the WTO. 'Unnecessary' trade costs were the focus of 16.4% of the challenges. Only one (1.1%) challenge remained unresolved and escalated to a trade dispute. Thirty-nine (41.9%) challenges focussed on labelling regulations, and 18 (19.4%) focussed on quality standards and restrictions on certain products like processed meats and cigarette flavourings. High-income countries raised 77.4% (n = 72) of all challenges raised against low- and lower-middle-income countries. We further identified 4 cases in Indonesia, Chile, Colombia, and Saudi Arabia in which challenges were associated with changes to food and beverage regulations. Data limitations precluded a comprehensive evaluation of policy impact and challenge validity. Policy makers appear to face significant pressure to design food, beverage, and tobacco regulations that other countries will deem consistent with trade rules. Trade-related influence on public health policy is likely to be understated by analyses limited to formal trade disputes.

Evidence-based medicine and epistemological imperialism: narrowing the divide between evidence and illness.

PubMed

Crowther, Helen; Lipworth, Wendy; Kerridge, Ian

2011-10-01

Evidence-based medicine (EBM) has been rapidly and widely adopted because it claims to provide a method for determining the safety and efficacy of medical therapies and public health interventions more generally. However, as others have noted, EBM may be riven through with cultural bias, both in the generation of evidence and in its translation. We suggest that technological and scientific advances in medicine accentuate and entrench these cultural biases, to the extent that they may invalidate the evidence we have about disease and its treatment. This creates a significant ethical, epistemological and ontological challenge for medicine. © 2011 Blackwell Publishing Ltd.

Multidrug-resistant organisms are creating a challenge for physicians treating the critically ill. As new antibiotics lag behind the emergence of worsening resistance, intensivists in countries with high rates of extensively drug-resistant bacteria are turning to inhaled antibiotics as adjunctive therapy. These drugs can provide high concentrations of drug in the lung that could not be achieved with intravenous antibiotics without significant systemic toxicity. This article summarizes current evidence describing the use of inhaled antibiotics for the treatment of bacterial ventilator-associated pneumonia and ventilator-associated tracheobronchitis. Preliminary data suggest aerosolized antimicrobials may effectively treat resistant pathogens with high minimum inhibitory concentrations. Copyright © 2017 Elsevier Inc. All rights reserved.

The case for undergraduate medical education in healthcare business and management.

PubMed

Hsu, Benson S; Hosokawa, Michael C; Maria, Bernard

2007-01-01

Current undergraduate medical education does notprepare students to approach the intricacies of healthcare business. This absence within medical education creates significant challenges for physicians throughout their careers. The field of academic medicine has clearly documented the need for medical education to prepare students for practice management, yet there exist only a small number of attempts at exposing students to healthcare business and management. The authors argue that this curriculum must start at the level ofundergraduate medical education. Furthermore, this curriculum must possess the basic components of support, integration, practicality, application, and continuation. Fulfilling these requirements will allow for the successful adaptation of the healthcare business and management curriculum.

Active mixing of complex fluids at the microscale

DOE PAGES

Ober, Thomas J.; Foresti, Daniele; Lewis, Jennifer A.

Mixing of complex fluids at low Reynolds number is fundamental for a broad range of applications, including materials assembly, microfluidics, and biomedical devices. Of these materials, yield stress fluids (and gels) pose the most significant challenges, especially when they must be mixed in low volumes over short timescales. New scaling relationships between mixer dimensions and operating conditions are derived and experimentally verified to create a framework for designing active microfluidic mixers that can efficiently homogenize a wide range of complex fluids. As a result, active mixing printheads are then designed and implemented for multimaterial 3D printing of viscoelastic inks withmore » programmable control of local composition.« less

Seamless Image Mosaicking via Synchronization

NASA Astrophysics Data System (ADS)

Santellani, E.; Maset, E.; Fusiello, A.

2018-05-01

This paper proposes an innovative method to create high-quality seamless planar mosaics. The developed pipeline ensures good robustness against many common mosaicking problems (e.g., misalignments, colour distortion, moving objects, parallax) and differs from other works in the literature because a global approach, known as synchronization, is used for image registration and colour correction. To better conceal the mosaic seamlines, images are cut along specific paths, computed using a Voronoi decomposition of the mosaic area and a shortest path algorithm. Results obtained on challenging real datasets show that the colour correction mitigates significantly the colour variations between the original images and the seams on the final mosaic are not evident.

Science, pseudoscience, and the frontline practitioner: the vaccination/autism debate.

PubMed

White, Erina

2014-01-01

This article demonstrates how misinformation concerning autism and vaccinations was created and suggests that social workers may be perfectly poised to challenge pseudoscience interpretations. Utilizing social network theory, this article illustrates how erroneous research, mass media, and public opinion led to a decreased use of vaccinations in the United States and a seven-fold increase in measles outbreaks. It traces the dissemination of spurious research results and demonstrates how information was transmitted via a system of social network nodes and community ties. This article encourages social workers, as frontline knowledge brokers, to counter misinformation, which may lead to significant public health consequences.

Medical school 2.0: How we developed a student-generated question bank using small group learning.

PubMed

Gooi, Adrian C C; Sommerfeld, Connor S

2015-01-01

The multiple-choice question (MCQ) is one of the most common methods for formative and summative assessment in medical school. Common challenges with this format include (1) creating vetted questions and (2) involving students in higher-order learning activities. Involving medical students in the creation of MCQs may ameliorate both of these challenges. What we did: We used a small group learning structure to develop a student-generated question bank. Students created their own MCQ based on self-study materials, and then reviewed each other's questions within small groups. Selected questions were reviewed with the class as a whole. All questions were later vetted by the instructor and incorporated into a question bank that students could access for formative learning. Post-session survey indicated that 91% of the students felt that the class-created MCQ question bank was a valuable resource, and 86% of students would be interested in collaborating with the class for creating practice questions in future sessions. Developing a student-generated question bank can improve the depth and interactivity of student learning, increase session enjoyment and provide a potential resource for student assessment.

Survey of business process management: challenges and solutions

NASA Astrophysics Data System (ADS)

Alotaibi, Youseef; Liu, Fei

2017-09-01

The current literature shows that creating a good framework on business process model (PM) is not an easy task. A successful business PM should have the ability to ensure accurate alignment between business processes (BPs) and information technology (IT) designs, provide security protection, manage the rapidly changing business environment and BPs, manage customer power, be flexible for reengineering and ensure that IT goals can be easily derived from business goals and hence an information system (IS) can be easily implemented. This article presents an overview of research in the business PM domain. We have presented a review of the challenges facing business PMs, such as misalignment between business and IT, difficulty of deriving IT goals from business goals, creating secured business PM, reengineering BPs, managing the rapidly changing BP and business environment and managing customer power. Also, it presents the limitations of existing business PM frameworks. Finally, we outline several guidelines to create good business PM and the possible further research directions in the business PM domain.

Modern microscope automation permits the collection of vast amounts of continuous anatomical imagery in both two and three dimensions. These large data sets present significant challenges for data storage, access, viewing, annotation and analysis. The cost and overhead of collecting and storing the data can be extremely high. Large data sets quickly exceed an individual's capability for timely analysis and present challenges in efficiently applying transforms, if needed. Finally annotated anatomical data sets can represent a significant investment of resources and should be easily accessible to the scientific community. The Viking application was our solution created to view and annotate a 16.5 TB ultrastructural retinal connectome volume and we demonstrate its utility in reconstructing neural networks for a distinctive retinal amacrine cell class. Viking has several key features. (1) It works over the internet using HTTP and supports many concurrent users limited only by hardware. (2) It supports a multi-user, collaborative annotation strategy. (3) It cleanly demarcates viewing and analysis from data collection and hosting. (4) It is capable of applying transformations in real-time. (5) It has an easily extensible user interface, allowing addition of specialized modules without rewriting the viewer. PMID:21118201

Geomagnetic referencing is becoming an increasingly attractive alternative to north-seeking gyroscopic surveys to achieve the precise wellbore positioning essential for success in today's complex drilling programs. However, the greater magnitude of variations in the geomagnetic environment at higher latitudes makes the application of geomagnetic referencing in those areas more challenging. Precise, real-time data on those variations from relatively nearby magnetic observatories can be crucial to achieving the required accuracy, but constructing and operating an observatory in these often harsh environments poses a number of significant challenges. Operational since March 2010, the Deadhorse Magnetic Observatory (DED), located in Deadhorse, Alaska, was created through collaboration between the United States Geological Survey (USGS) and a leading oilfield services supply company. DED was designed to produce real-time geomagnetic data at the required level of accuracy, and to do so reliably under the extreme temperatures and harsh weather conditions often experienced in the area. The observatory will serve a number of key scientific communities as well as the oilfield drilling industry, and has already played a vital role in the success of several commercial ventures in the area, providing essential, accurate data while offering significant cost and time savings, compared with traditional surveying techniques.

The Long Way From Government Open Data to Mobile Health Apps: Overcoming Institutional Barriers in the US Federal Government.

PubMed

Mergel, Ines

2014-12-23

Government agencies in the United States are creating mobile health (mHealth) apps as part of recent policy changes initiated by the White House's Digital Government Strategy. The objective of the study was to understand the institutional and managerial barriers for the implementation of mHealth, as well as the resulting adoption pathways of mHealth. This article is based on insights derived from qualitative interview data with 35 public managers in charge of promoting the reuse of open data through Challenge.gov, the platform created to run prizes, challenges, and the vetting and implementation of the winning and vendor-created apps. The process of designing apps follows three different pathways: (1) entrepreneurs start to see opportunities for mobile apps, and develop either in-house or contract out to already vetted Web design vendors; (2) a top-down policy mandates agencies to adopt at least two customer-facing mobile apps; and (3) the federal government uses a policy instrument called "Prizes and Challenges", encouraging civic hackers to design health-related mobile apps using open government data from HealthData.gov, in combination with citizen needs. All pathways of the development process incur a set of major obstacles that have to be actively managed before agencies can promote mobile apps on their websites and app stores. Beyond the cultural paradigm shift to design interactive apps and to open health-related data to the public, the managerial challenges include accessibility, interoperability, security, privacy, and legal concerns using interactive apps tracking citizen.

Online faculty development for creating E-learning materials.

2014-01-01

Faculty who want to develop e-learning materials face pedagogical challenges of transforming instruction for the online environment, especially as many have never experienced online learning themselves. They face technical challenges of learning new software and time challenges of not all being able to be in the same place at the same time to learn these new skills. The objective of the Any Day Any Place Teaching (ADAPT) faculty development program was to create an online experience in which faculty could learn to produce e-learning materials. The ADAPT curriculum included units on instructional design, copyright principles and peer review, all for the online environment, and units on specific software tools. Participants experienced asynchronous and synchronous methods, including a learning management system, PC-based videoconferencing, online discussions, desktop sharing, an online toolbox and optional face-to-face labs. Project outcomes were e-learning materials developed and participants' evaluations of the experience. Likert scale responses for five instructional units (quantitative) were analyzed for distance from neutral using one-sample t-tests. Interview data (qualitative) were analyzed with assurance of data trustworthiness and thematic analysis techniques. Participants were 27 interprofessional faculty. They evaluated the program instruction as easy to access, engaging and logically presented. They reported increased confidence in new skills and increased awareness of copyright issues, yet continued to have time management challenges and remained uncomfortable about peer review. They produced 22 new instructional materials. Online faculty development methods are helpful for faculty learning to create e-learning materials. Recommendations are made to increase the success of such a faculty development program.

COOP+ project: Promoting the cooperation of international Research Infrastructures to address global environmental challenges.

2016-12-01

Humanity must face enormous environmental challenges including biodiversity decline, climate change, ocean acidification, sea level rise and overpopulation. The research infrastructures (RIs) created in the last decades worldwide cover a wide range of spatial and thematic scales and collect information about the functioning of Earth ecosystems. However, we need to go one step forward: understand and simulate the functioning of the Earth as a complex system in a global change scenario. Cooperation among international RIs as well as multidisciplinary work are mandatory to achieve this challenging objective. COOP+ (EU Horizon 2020 project) aims to strengthen the links and coordination of European environmental RIs with their international counterparts. COOP+ will create cooperation threads among international research infrastructures using environmental Global Challenges (GCs) as thematic guidelines. These GCs are polyhedral and sometimes wicked problems that threaten the sustainability of our modern societies from a social and environmental perspective. This contribution describes how COOP+ uses GCs as guidelines to foster cooperation among RIs. First we have created an open survey to collect ideas about GCs within the different scientific communities. We present the structure of this survey as well as the preliminary information that it contains. The survey will be accepting responses during the project life (September 2018). We also describe the structure of a template that will be used to collaboratively characterize some selected GCs under the point of view of RIs. The main idea is to assess how RIs can be useful to address global environmental problems. We encourage all scientists related to RIs communities to participate in this process.

Experiencing authenticity - the core of student learning in clinical practice.

PubMed

Manninen, Katri

2016-10-01

Learning in clinical practice is challenging regarding organizational and pedagogical issues. Clinical education wards are one way to meet these challenges by focusing on both patient care and student learning. However, more knowledge is needed about how students' learning can be enhanced and about patients' and supervisors' roles in these settings. The aim was to explore nursing students' learning on a clinical education ward with an explicit pedagogical framework. Semi-structured interviews of students were analyzed using qualitative content analysis and an ethnographic study including observations and follow-up interviews of students, patients and supervisors was conducted. The core of student meaningful learning experiences both external and internal authenticity. Students in early stages immediately created mutual relationships, experienced both external and internal authenticity, and patients became active participants in student learning. Without a mutual relationship, patients passively let students practice on their bodies. Students nearing graduation experienced only external authenticity, creating uncertainty as a threshold for learning. Caring for patients with complex needs helped students overcome the threshold and experience internal authenticity. Supervisors' challenges were to balance patient care and student learning by working as a team. They supported students coping with the complex challenges on the ward. Students need to experience external and internal authenticity to make learning meaningful. Experiencing authenticity, involving meaning-making processes and knowledge construction, is linked to transformative learning and overcoming thresholds. Therefore, an explicit pedagogical framework, based on patient-centredness, peer learning and the supervisory team, creates the prerequisites for experiencing external and internal authenticity.

Confronting inequities: A scoping review of the literature on pharmacist practice and health-related disparities.

Wenger, Lisa M; Rosenthal, Meagen; Sharpe, Jane Pearson; Waite, Nancy

2016-01-01

An expanding body of literature is exploring the presence and impact of health and health care disparities among marginalized populations. This research challenges policy makers, health professionals, and scholars to examine how unjust and avoidable inequities are created at the societal, institutional, and individual level, and explore strategies for mitigating challenges. Recognizing the significance of this broader conversation, this scoping review provides an overview of pharmacy-specific research attentive to health-related disparities. Following Arksey and O'Malley's framework, a rigorous screening process yielded 93 peer-reviewed and 23 grey literature articles, each analyzed for core themes. Lending critical insight to how pharmacy practice researchers are conceptualizing and measuring health inequities, this review highlights three paths of inquiry evident across this literature, including research focused on what pharmacists know about marginalized groups, how pharmacists perceive these groups, and how they provide services. Striving to drive research and practice forward, this review details research gaps and opportunities, including a need to expand the scope of research and integrate knowledge. As pharmacists endeavor to provide equitable and impactful patient care, it is essential to understand challenges, and build strong evidence for meaningful action. Copyright © 2016 Elsevier Inc.

Climate Change Mitigation Challenge for Wood Utilization-The Case of Finland.

PubMed

Soimakallio, Sampo; Saikku, Laura; Valsta, Lauri; Pingoud, Kim

2016-05-17

The urgent need to mitigate climate change invokes both opportunities and challenges for forest biomass utilization. Fossil fuels can be substituted by using wood products in place of alternative materials and energy, but wood harvesting reduces forest carbon sink and processing of wood products requires material and energy inputs. We assessed the extended life cycle carbon emissions considering substitution impacts for various wood utilization scenarios over 100 years from 2010 onward for Finland. The scenarios were based on various but constant wood utilization structures reflecting current and anticipated mix of wood utilization activities. We applied stochastic simulation to deal with the uncertainty in a number of input variables required. According to our analysis, the wood utilization decrease net carbon emissions with a probability lower than 40% for each of the studied scenarios. Furthermore, large emission reductions were exceptionally unlikely. The uncertainty of the results were influenced clearly the most by the reduction in the forest carbon sink. There is a significant trade-off between avoiding emissions through fossil fuel substitution and reduction in forest carbon sink due to wood harvesting. This creates a major challenge for forest management practices and wood utilization activities in responding to ambitious climate change mitigation targets.

Drugs in development for toxoplasmosis: advances, challenges, and current status.

PubMed

Alday, P Holland; Doggett, Joseph Stone

2017-01-01

Toxoplasma gondii causes fatal and debilitating brain and eye diseases. Medicines that are currently used to treat toxoplasmosis commonly have toxic side effects and require prolonged courses that range from weeks to more than a year. The need for long treatment durations and the risk of relapsing disease are in part due to the lack of efficacy against T. gondii tissue cysts. The challenges for developing a more effective treatment for toxoplasmosis include decreasing toxicity, achieving therapeutic concentrations in the brain and eye, shortening duration, eliminating tissue cysts from the host, safety in pregnancy, and creating a formulation that is inexpensive and practical for use in resource-poor areas of the world. Over the last decade, significant progress has been made in identifying and developing new compounds for the treatment of toxoplasmosis. Unlike clinically used medicines that were repurposed for toxoplasmosis, these compounds have been optimized for efficacy against toxoplasmosis during preclinical development. Medicines with enhanced efficacy as well as features that address the unique aspects of toxoplasmosis have the potential to greatly improve toxoplasmosis therapy. This review discusses the facets of toxoplasmosis that are pertinent to drug design and the advances, challenges, and current status of preclinical drug research for toxoplasmosis.

The need for long treatment durations and the risk of relapsing disease are in part due to the lack of efficacy against T. gondii tissue cysts. The challenges for developing a more effective treatment for toxoplasmosis include decreasing toxicity, achieving therapeutic concentrations in the brain and eye, shortening duration, eliminating tissue cysts from the host, safety in pregnancy, and creating a formulation that is inexpensive and practical for use in resource-poor areas of the world. Over the last decade, significant progress has been made in identifying and developing new compounds for the treatment of toxoplasmosis. Unlike clinically used medicines that were repurposed for toxoplasmosis, these compounds have been optimized for efficacy against toxoplasmosis during preclinical development. Medicines with enhanced efficacy as well as features that address the unique aspects of toxoplasmosis have the potential to greatly improve toxoplasmosis therapy. This review discusses the facets of toxoplasmosis that are pertinent to drug design and the advances, challenges, and current status of preclinical drug research for toxoplasmosis. PMID:28182168
