There is substantial evidence that health and health-care experiences vary along ethnic lines and the need to understand and tackle ethnic health inequalities has repeatedly been highlighted. Research into ethnicity and health raises ethical, theoretical and methodological issues and, as the volume of research in this area grows, so too do concerns regarding its scientific rigour and reporting, and its contribution to reducing inequalities. Guidance may be helpful in encouraging researchers to adopt standard practices in the design, conduct and reporting of research. However, past efforts at introducing such guidance have had limited impact on research practice, and the diversity of disciplinary perspectives on the key challenges and solutions may undermine attempts to derive and promote guiding principles. A consensus building Delphi exercise--the first of its kind in this area of research practice--was undertaken with leading academics, practitioners and policymakers from a broad range of disciplinary backgrounds to assess whether consensus on key principles could be achieved. Ten key principles for conducting research on ethnicity and health emerged, covering: the aims of research in this field; how such research should be framed and focused; key design-related considerations; and the direction of future research. Despite some areas of dispute, participants were united by a common concern that the generation and application of research evidence should contribute to better health-care experiences and health outcomes for minority ethnic people. The principles provide a strong foundation to guide future ethnicity-related research and build a broader international consensus.

Green tribology: principles, research areas and challenges.

Nosonovsky, Michael; Bhushan, Bharat

2010-10-28

In this introductory paper for the Theme Issue on green tribology, we discuss the concept of green tribology and its relation to other areas of tribology as well as other 'green' disciplines, namely, green engineering and green chemistry. We formulate the 12 principles of green tribology: the minimization of (i) friction and (ii) wear, (iii) the reduction or complete elimination of lubrication, including self-lubrication, (iv) natural and (v) biodegradable lubrication, (vi) using sustainable chemistry and engineering principles, (vii) biomimetic approaches, (viii) surface texturing, (ix) environmental implications of coatings, (x) real-time monitoring, (xi) design for degradation, and (xii) sustainable energy applications. We further define three areas of green tribology: (i) biomimetics for tribological applications, (ii) environment-friendly lubrication, and (iii) the tribology of renewable-energy application. The integration of these areas remains a primary challenge for this novel area of research. We also discuss the challenges of green tribology and future directions of research.

Gauge theories under incorporation of a generalized uncertainty principle

International Nuclear Information System (INIS)

Kober, Martin

2010-01-01

There is considered an extension of gauge theories according to the assumption of a generalized uncertainty principle which implies a minimal length scale. A modification of the usual uncertainty principle implies an extended shape of matter field equations like the Dirac equation. If there is postulated invariance of such a generalized field equation under local gauge transformations, the usual covariant derivative containing the gauge potential has to be replaced by a generalized covariant derivative. This leads to a generalized interaction between the matter field and the gauge field as well as to an additional self-interaction of the gauge field. Since the existence of a minimal length scale seems to be a necessary assumption of any consistent quantum theory of gravity, the gauge principle is a constitutive ingredient of the standard model, and even gravity can be described as gauge theory of local translations or Lorentz transformations, the presented extension of gauge theories appears as a very important consideration.

Mackert, Michael; Guadagno, Marie; Champlin, Sara

2015-01-01

Communication researchers, recognizing the message sent is not necessarily the same as the message received, have incorporated the perspective of advertising professionals into the study of advertising effects. Health marketing research could similarly benefit from incorporating this largely absent perspective into the academic and policy debate surrounding the impact of advertising on health issues ranging from obesity to alcohol use. This commentary serves as a call to action to stakeholders in this academic and policy debate: focus on the perspective of advertising professionals to enrich health marketing and public health research in which advertising is the delivery vehicle for health messages.

Game Design Principles based on Human Error

2016-03-01

Full Text Available This paper displays the result of the authors’ research regarding to the incorporation of Human Error, through design principles, to video game design. In a general way, designers must consider Human Error factors throughout video game interface development; however, when related to its core design, adaptations are in need, since challenge is an important factor for fun and under the perspective of Human Error, challenge can be considered as a flaw in the system. The research utilized Human Error classifications, data triangulation via predictive human error analysis, and the expanded flow theory to allow the design of a set of principles in order to match the design of playful challenges with the principles of Human Error. From the results, it was possible to conclude that the application of Human Error in game design has a positive effect on player experience, allowing it to interact only with errors associated with the intended aesthetics of the game.

Incorporating microbiota data into epidemiologic models: examples from vaginal microbiota research.

van de Wijgert, Janneke H; Jespers, Vicky

2016-05-01

Next generation sequencing and quantitative polymerase chain reaction technologies are now widely available, and research incorporating these methods is growing exponentially. In the vaginal microbiota (VMB) field, most research to date has been descriptive. The purpose of this article is to provide an overview of different ways in which next generation sequencing and quantitative polymerase chain reaction data can be used to answer clinical epidemiologic research questions using examples from VMB research. We reviewed relevant methodological literature and VMB articles (published between 2008 and 2015) that incorporated these methodologies. VMB data have been analyzed using ecologic methods, methods that compare the presence or relative abundance of individual taxa or community compositions between different groups of women or sampling time points, and methods that first reduce the complexity of the data into a few variables followed by the incorporation of these variables into traditional biostatistical models. To make future VMB research more clinically relevant (such as studying associations between VMB compositions and clinical outcomes and the effects of interventions on the VMB), it is important that these methods are integrated with rigorous epidemiologic methods (such as appropriate study designs, sampling strategies, and adjustment for confounding).

Khodyakov, Dmitry; Mikesell, Lisa; Schraiber, Ron; Booth, Marika; Bromley, Elizabeth

2016-05-01

The transfer of new discoveries into both clinical practice and the wider community calls for reliance on interdisciplinary translational teams that include researchers with different areas of expertise, representatives of health care systems and community organizations, and patients. Engaging new stakeholders in research, however, calls for a reconsideration or expansion of the meaning of ethics in translational research. We explored expert opinion on the applicability of ethical principles commonly practiced in community-engaged research (CEnR) to translational research. To do so, we conducted 2 online, modified-Delphi panels with 63 expert stakeholders who iteratively rated and discussed 9 ethical principles commonly used in CEnR in terms of their importance and feasibility for use in translational research. The RAND/UCLA appropriateness method was used to analyze the data and determine agreement and disagreement among participating experts. Both panels agreed that ethical translational research should be "grounded in trust." Although the academic panel endorsed "culturally appropriate" and "forthcoming with community about study risks and benefits," the mixed academic-community panel endorsed "scientifically valid" and "ready to involve community in interpretation and dissemination" as important and feasible principles of ethical translational research. These findings suggest that in addition to protecting human subjects, contemporary translational science models need to account for the interests of, and owe ethical obligations to, members of the investigative team and the community at large.

Engageability: a new sub-principle of the learnability principle in human-computer interaction

Directory of Open Access Journals (Sweden)

B Chimbo

2011-12-01

Full Text Available The learnability principle relates to improving the usability of software, as well as users’ performance and productivity. A gap has been identified as the current definition of the principle does not distinguish between users of different ages. To determine the extent of the gap, this article compares the ways in which two user groups, adults and children, learn how to use an unfamiliar software application. In doing this, we bring together the research areas of human-computer interaction (HCI, adult and child learning, learning theories and strategies, usability evaluation and interaction design. A literature survey conducted on learnability and learning processes considered the meaning of learnability of software applications across generations. In an empirical investigation, users aged from 9 to 12 and from 35 to 50 were observed in a usability laboratory while learning to use educational software applications. Insights that emerged from data analysis showed different tactics and approaches that children and adults use when learning unfamiliar software. Eye tracking data was also recorded. Findings indicated that subtle re- interpretation of the learnability principle and its associated sub-principles was required. An additional sub-principle, namely engageability was proposed to incorporate aspects of learnability that are not covered by the existing sub-principles. Our re-interpretation of the learnability principle and the resulting design recommendations should help designers to fulfill the varying needs of different-aged users, and improve the learnability of their designs.

Based on basic formula for core refueling, the optimal refueling principle for cores with fuel assemblies of different burnup are suggested. Some conclusions derived from this principle are given. Calculation formula for different refueling scheme and computation programme are derived and used for the HFETR typical core loading with different refueling scheme. With the suggested core fuel consuming index, core fuel managements of 24 cycles in 10 years operation of HFETR were analyzed. Results show that the application of optimal refueling principle can greatly save the fuel consuming. Direction of HFETR core fuel management research was also di cussed

Recommendations for sex/gender neuroimaging research: key principles and implications for research design, analysis, and interpretation

Rippon, Gina; Jordan-Young, Rebecca; Kaiser, Anelis; Fine, Cordelia

2014-01-01

Neuroimaging (NI) technologies are having increasing impact in the study of complex cognitive and social processes. In this emerging field of social cognitive neuroscience, a central goal should be to increase the understanding of the interaction between the neurobiology of the individual and the environment in which humans develop and function. The study of sex/gender is often a focus for NI research, and may be motivated by a desire to better understand general developmental principles, mental health problems that show female-male disparities, and gendered differences in society. In order to ensure the maximum possible contribution of NI research to these goals, we draw attention to four key principles—overlap, mosaicism, contingency and entanglement—that have emerged from sex/gender research and that should inform NI research design, analysis and interpretation. We discuss the implications of these principles in the form of constructive guidelines and suggestions for researchers, editors, reviewers and science communicators. PMID:25221493

2012-03-01

This paper presents the rationale for the choice of participants in qualitative research in contrast with that of probability sampling principles in epidemiological research. For a better understanding of the differences, concepts of nomothetic and ideographic generalizability, as well as those of transferability and reflexivity, are proposed, Fundamentals of the main types of sampling commonly used in qualitative research, and the meaning of the concept of saturation are mentioned. Finally, some reflections on the controversies that have arisen in recent years on various paradigmatic perspectives from which to conduct qualitative research, their possibilities of combination with epidemiological research, and some implications for the study of health issues are presented.

Evolutionary principles and their practical application

Evolutionary principles are now routinely incorporated into medicine and agriculture. Examples include the design of treatments that slow the evolution of resistance by weeds, pests, and pathogens, and the design of breeding programs that maximize crop yield or quality. Evolutionary principles...... are also increasingly incorporated into conservation biology, natural resource management, and environmental science. Examples include the protection of small and isolated populations from inbreeding depression, the identification of key traits involved in adaptation to climate change, the design...... of harvesting regimes that minimize unwanted life-history evolution, and the setting of conservation priorities based on populations, species, or communities that harbor the greatest evolutionary diversity and potential.

Alt, Mary; Meyers, Christina; Ancharski, Alexandra

2012-01-01

Language treatment for children with specific language impairment (SLI) often takes months to achieve moderate results. Interventions often do not incorporate the principles that are known to affect learning in unimpaired learners. To outline some key findings about learning in typical populations and to suggest a model of how they might be applied to language treatment design as a catalyst for further research and discussion. Three main principles of implicit learning are reviewed: variability, complexity and sleep-dependent consolidation. After explaining these principles, evidence is provided as to how they influence learning tasks in unimpaired learners. Information is reviewed on principles of learning as they apply to impaired populations, current treatment designs are also reviewed that conform to the principles, and ways in which principles of learning might be incorporated into language treatment design are demonstrated. This paper provides an outline for how theoretical knowledge might be applied to clinical practice in an effort to promote discussion. Although the authors look forward to more specific details on how the principles of learning relate to impaired populations, there is ample evidence to suggest that these principles should be considered during treatment design. © 2012 Royal College of Speech and Language Therapists.

Palliative care has evolved to encompass early integration, with evaluation of patient and organisational outcomes. However, little is known of staff's experiences and adaptations when change occurs within palliative care services. To explore staff experiences of a transition from a service predominantly focused on end-of-life care to a specialist service encompassing early integration. Qualitative research incorporating interviews, focus groups and anonymous semi-structured questionnaires. Data were analysed using a comparative approach. Service activity data were also aggregated. A total of 32 medical, nursing, allied health and administrative staff serving a 22-bed palliative care unit and community palliative service, within a large health service. Patients cared for within the new model were significantly more likely to be discharged home (7.9% increase, p = 0.003) and less likely to die in the inpatient unit (10.4% decrease, p management was considered valuable, nurses particularly found additional skill expectations challenging, and perceived patients' acute care needs as detracting from emotional and end-of-life care demands. Staff views varied on whether they regarded the new model's faster-paced work-life as consistent with fundamental palliative care principles. Less certainty about care goals, needing to prioritise care tasks, reduced shared support rituals and other losses could intensify stress, leading staff to develop personalised coping strategies. Services introducing and researching innovative models of palliative care need to ensure adequate preparation, maintenance of holistic care principles in faster work-paced contexts and assist staff dealing with demands associated with caring for patients at different stages of illness trajectories. © The Author(s) 2015.

This paper analyses Rawls's celebrated difference principle, and its lexicographic extension, in societies with a finite and an infinite number of agents. A unified framework of analysis is set up, which allows one to characterise Rawlsian egalitarian principles by means of a weaker version of a new axiom - the Harm Principle - recently proposed by marven09. This is quite surprising, because the Harm principle is meant to capture a liberal requirement of noninterference and it incorporates no...

Conceptualizing strategic environmental assessment: Principles, approaches and research directions

International Nuclear Information System (INIS)

Noble, Bram; Nwanekezie, Kelechi

2017-01-01

Increasing emphasis has been placed in recent years on transitioning strategic environmental assessment (SEA) away from its environmental impact assessment (EIA) roots. Scholars have argued the need to conceptualize SEA as a process designed to facilitate strategic thinking, thus enabling transitions toward sustainability. The practice of SEA, however, remains deeply rooted in the EIA tradition and scholars and practitioners often appear divided on the nature and purpose of SEA. This paper revisits the strategic principles of SEA and conceptualizes SEA as a multi-faceted and multi-dimensional assessment process. It is suggested that SEA can be conceptualized as series of approaches operating along a spectrum from less to more strategic – from impact assessment-based to strategy-based – with each approach to SEA differentiated by the specific objectives of SEA application and the extent to which strategic principles are reflected in its design and implementation. Advancing the effectiveness of SEA requires a continued research agenda focused on improving the traditional SEA approach, as a tool to assess the impacts of policies, plans and programs (PPPs). Realizing the full potential of SEA, however, requires a new research agenda — one focused on the development and testing of a deliberative governance approach to SEA that can facilitate strategic innovations in PPP formulation and drive transitions in short-term policy and initiatives based on longer-term thinking. - Highlights: • SEA facilitates strategic thinking, enabling transitions toward sustainability. • SEA is conceptualized as a spectrum of approaches, from IA-based to strategy-based. • Each approach variably emphasizes strategic principles in its design and practice. • There is no one conceptualization of SEA that is best, SEA is fit for PPP purpose. • Research is needed to advance SEA to facilitate strategic PPP transformations.

Towards a community effort to identify ethical principles for research in hydrology

Science.gov (United States)

Montanari, Alberto

2010-05-01

The hydrological community in Europe is growing rapidly in both size and, more importantly, scientific relevance and integrity. The Hydrological Sciences (HS) Division of EGU actively is promoting the above development by identifying research targets, stimulating the involvement of young scientists and managing a scientific open access journal based on a public peer review process. The management of the Division itself and the organisation of the General Assembly are carried out transparently, with the aim to seek an improved involvement of top and young scientists, with a bottom up approach. I believe the HS community is animated by a strong enthusiasm which, however, is not adequately supported by economical funding. In my opinion this is a major problem which HS should consider and discuss. The relevance of the societal and environmental problems dealt with by hydrologists, in a professional way and with exceptional scientific skills, is without doubt and therefore the limited amount of funding is not justified in practice. In my opinion, in order to refine the structure of the HS community, and promote its visibility, we should formally identify HS ethical principles for research in environmental science. The principles should highlight the role of hydrology as well as the ethical and scientific solidity of the HS community. Establishing ethical principles is even more important in view of the transparent approach HS is adopting for reviewing and publishing contributions and in view of the increasing need to transparently prove how public funding for research is administered. Establishing ethical principles for hydrology is not a trivial task. Hydrology is characterised by a relevant uncertainty in data, models and parameters. Hydrology is also relying on a large variety of approaches, ranging from statistical to physically based. The purpose of this poster is to present a collection of ethical principles for scientific research presented by the literature and

Cosmological principle

International Nuclear Information System (INIS)

Wesson, P.S.

1979-01-01

The Cosmological Principle states: the universe looks the same to all observers regardless of where they are located. To most astronomers today the Cosmological Principle means the universe looks the same to all observers because density of the galaxies is the same in all places. A new Cosmological Principle is proposed. It is called the Dimensional Cosmological Principle. It uses the properties of matter in the universe: density (rho), pressure (p), and mass (m) within some region of space of length (l). The laws of physics require incorporation of constants for gravity (G) and the speed of light (C). After combining the six parameters into dimensionless numbers, the best choices are: 8πGl 2 rho/c 2 , 8πGl 2 rho/c 4 , and 2 Gm/c 2 l (the Schwarzchild factor). The Dimensional Cosmological Principal came about because old ideas conflicted with the rapidly-growing body of observational evidence indicating that galaxies in the universe have a clumpy rather than uniform distribution

Full Text Available The present paper assembles contributions from the areas of education, psychology, cognitive science, and of course, neuroeducation itself to introduce the basic principles of research in the field of neuroeducation studies. It is particularly important, as such it is a useful way to justify researchers about what neuroeducation as a specific domain do that no other field can do as well or cannot do at all. Based on the literature reviewed, neuroeducational research can be understood as an interdisciplinary endeavor to develop an insightful understanding and holistic picture of problems related to learning and education. It thus epistemologically is based on an integrated methodological pluralism paradigm. This requires researchers to understand multiple methods and methodologies and employ as they formulate their own research projects. Researchers have a critical role to play in providing systematic evidence and conclusions that are scientifically valid and reliable and educationally relevant and usable. One significant implication of this argument is the need to strengthen the quality of the research component in graduate programs of the field and train interested researchers in the identification and formulation of relevant research questions.

EcoPrinciples Connect: A Pilot Project Matching Ecological Principles with Available Data to Promote Ecosystem-Based Management

Ocean and coastal practitioners work within existing financial constraints, jurisdictions, and legislative authorities to manage coastal and marine resources while seeking to promote and maintain a healthy and productive coastal economy. Fulfilling this mandate necessitates incorporation of best available science, including ecosystem-based management (EBM) into coastal and ocean management decisions. To do this, many agencies seek ways to apply lessons from ecological theory into their decision processes. However, making direct connections between science and management can be challenging, in part because there is no process for linking ecological principles (e.g., maintaining species diversity, habitat diversity, connectivity and populations of key species) with available data. Here we explore how incorporating emerging data and methods into resource management at a local scale can improve the overall health of our coastal and marine ecosystems. We introduce a new web-based interface, EcoPrinciples Connect, that links marine managers to scientific and geospatial information through the lens of these ecological principles, ultimately helping managers become more efficient, more consistent, and advance the integration of EBM. The EcoPrinciples Connect tool grew directly out of needs identified in response to a Center for Ocean Solutions reference guide, Incorporating Ecological Principles into California Ocean and Coastal Management: Examples from Practice. Here we illustrate how we have worked to translate the information in this guide into a co-developed, user-centric tool for agency staff. Specifically, we present a pilot project where we match publicly available data to the ecological principles for the California San Francisco Bay Conservation and Development Commission. We will share early lessons learned from pilot development and highlight opportunities for future transferability to an expanded group of practitioners.

2015-09-01

Qualitative methods are increasingly being used in emergency care research. Rigorous qualitative methods can play a critical role in advancing the emergency care research agenda by allowing investigators to generate hypotheses, gain an in-depth understanding of health problems or specific populations, create expert consensus, and develop new intervention and dissemination strategies. This article, Part I of a two-article series, provides an introduction to general principles of applied qualitative health research and examples of its common use in emergency care research, describing study designs and data collection methods most relevant to our field, including observation, individual interviews, and focus groups. In Part II of this series, we will outline the specific steps necessary to conduct a valid and reliable qualitative research project, with a focus on interview-based studies. These elements include building the research team, preparing data collection guides, defining and obtaining an adequate sample, collecting and organizing qualitative data, and coding and analyzing the data. We also discuss potential ethical considerations unique to qualitative research as it relates to emergency care research. © 2015 by the Society for Academic Emergency Medicine.

The meaning of the EPSRC principles of robotics

Science.gov (United States)

Bryson, Joanna J.

2017-04-01

In revisiting the Principles of Robotics (as we do in this special issue), it is important to carefully consider their full meaning - their history, the intentions behind them, and their actual societal impact to date. Here I address first the meaning of the document as a whole, then of its constituent parts. Further, I describe the nature of policy, and use the Principles as a case study to discuss how government and academia can interact in constructing policy. I defend the Principles and their main themes: that commercially manufactured robots should not be responsible parties under the law, and that users should not be deceived about robots' capacities or moral status. This perspective allows for the incorporation of robots immediately into UK society and law - the objective of the Principles. The Principles were not designed for every conceivable robot, but rather serve in part as design specifications for robots to be incorporated as legal products into British society.

Gaps exist in researchers' understanding of the 'practice' of community governance in relation to research with Aboriginal and Torres Strait Islander peoples. We examine Aboriginal community governance of two rural NSW research projects by applying principles-based criteria from two independent sources. One research project possessed a strong Aboriginal community governance structure and evaluated a 2-year healthy lifestyle program for children; the other was a 5-year cohort study examining factors influencing the mental health and well-being of participants. The National Health and Medical Research Council of Australia's 'Values and ethics: guidelines for ethical conduct in Aboriginal and Torres Strait Islander research' and 'Ten principles relevant to health research among Indigenous Australian populations' described by experts in the field. Adopt community-based participatory research constructs. Develop clear governance structures and procedures at the beginning of the study and allow sufficient time for their establishment. Capacity-building must be a key component of the research. Ensure sufficient resources to enable community engagement, conduct of research governance procedures, capacity-building and results dissemination. The implementation of governance structures and procedures ensures research addresses the priorities of the participating Aboriginal and Torres Strait Islander communities, minimises risks and improves outcomes for the communities. Principles-based Aboriginal and Torres Strait Islander community governance of research is very achievable. Next steps include developing a comprehensive evidence base for appropriate governance structures and procedures, and consolidating a suite of practical guides for structuring clear governance in health research. © 2015 National Rural Health Alliance Inc.

From principles to action: Applying the National Research Council's principles for effective decision support to the Federal Emergency Management Agency's watch office

2016-03-01

Full Text Available The National Research Council (NRC proposed six principles for effective decision support in its 2009 report Informing Decisions in a Changing Climate. We structured a collaborative project between the Federal Emergency Management Agency Region R9 (FEMA R9, the Western Region Headquarters of the National Weather Service (WR-NWS, and the Climate Assessment of the Southwest (CLIMAS at the University of Arizona around the application of the NRC principles. The goal of the project was to provide FEMA R9's Watch Office with climate information scaled to their temporal and spatial interests to aid them in assessing the potential risk of flood disasters. We found that we needed specific strategies and activities in order to apply the principles effectively. By using a set of established collaborative research approaches we were better able to assess FEMA R9's information needs and WR-NWS's capacity to meet those needs. Despite our diligent planning of engagement strategies, we still encountered some barriers to transitioning our decision support tool from research to operations. This paper describes our methods for planning and executing a three-party collaborative effort to provide climate services, the decision support tool developed through this process, and the lessons we will take from this deliberate collaborative process to our future work and implications of the NRC principles for the broader field of climate services.

Graphical abstract: - Highlights: • Fabrication of tantalum incorporated diamonds films using HFCVD technique. • Decrease in resistivity by increasing tantalum content in diamond thin films. • Electronic structure calculations of tantalum incorporated diamonds films through VASP code. • A rise of bond length and bond angles by addition of tantalum in the diamond lattice. • Confirmation of decrease of resistivity by adding tantalum due to creation of impurity states in the bandgap. - Abstract: Tantalum (Ta) incorporated diamond films are synthesized on silicon substrate by chemical vapor deposition under gas mixture of CH{sub 4} + H{sub 2}. Characterizations of the resulting films indicate that morphology and resistivity of as-grown diamond films are significantly influenced by the process parameters and the amount of tantalum incorporated in the diamond films. XRD plots reveal that diamond films are composed of TaC along with diamond for higher concentration of tantalum and Ta{sub 2}C phases for lower concentration of tantalum. EDS spectra confirms the existence of tantalum in the diamond films. Resistivity measurements illustrate a sudden fall of about two orders of magnitude by the addition of tantalum in the diamond films. Band structure of Ta-incorporated diamond has been investigated based on density functional theory (DFT) using VASP code. Band structure calculations lead to the semiconducting behavior of Ta-incorporated diamond films because of the creation of defects states inside the band gap extending towards conduction band minimum. Present DFT results support experimental trend of resistivity that with the incorporation of tantalum into diamond lattice causes a decrease in the resistivity of diamond films so that tantalum-incorporated diamond films behave like a good semiconductor.

Evolutionary principles are now routinely incorporated into medicine and agriculture. Examples include the design of treatments that slow the evolution of resistance by weeds, pests, and pathogens, and the design of breeding programs that maximize crop yield or quality. Evolutionary principles are also increasingly incorporated into conservation biology, natural resource management, and environmental science. Examples include the protection of small and isolated populations from inbreeding depression, the identification of key traits involved in adaptation to climate change, the design of harvesting regimes that minimize unwanted life-history evolution, and the setting of conservation priorities based on populations, species, or communities that harbor the greatest evolutionary diversity and potential. The adoption of evolutionary principles has proceeded somewhat independently in these different fields, even though the underlying fundamental concepts are the same. We explore these fundamental concepts under four main themes: variation, selection, connectivity, and eco-evolutionary dynamics. Within each theme, we present several key evolutionary principles and illustrate their use in addressing applied problems. We hope that the resulting primer of evolutionary concepts and their practical utility helps to advance a unified multidisciplinary field of applied evolutionary biology.

The simplicity principle in perception and cognition.

Science.gov (United States)

Feldman, Jacob

2016-09-01

The simplicity principle, traditionally referred to as Occam's razor, is the idea that simpler explanations of observations should be preferred to more complex ones. In recent decades the principle has been clarified via the incorporation of modern notions of computation and probability, allowing a more precise understanding of how exactly complexity minimization facilitates inference. The simplicity principle has found many applications in modern cognitive science, in contexts as diverse as perception, categorization, reasoning, and neuroscience. In all these areas, the common idea is that the mind seeks the simplest available interpretation of observations- or, more precisely, that it balances a bias toward simplicity with a somewhat opposed constraint to choose models consistent with perceptual or cognitive observations. This brief tutorial surveys some of the uses of the simplicity principle across cognitive science, emphasizing how complexity minimization in a number of forms has been incorporated into probabilistic models of inference.

As policymakers and managers work to mitigate the effects of rapid anthropogenic environmental changes, they need to consider organisms’ responses. In light of recent evidence that evolution can be quite rapid, this now includes evolutionary responses. Evolutionary principles have a long history...... in conservation biology, and the necessary next step for the field is to consider ways in which conservation policy makers and managers can proactively manipulate evolutionary processes to achieve their goals. In this review, we aim to illustrate the potential conservation benefits of an increased understanding...... of evolutionary history and prescriptive manipulation of three basic evolutionary factors: selection, variation, and gene flow. For each, we review and propose ways that policy makers and managers can use evolutionary thinking to preserve threatened species, combat pest species, or reduce undesirable evolutionary...

Principles that underpin effective school-based drug education.

2002-01-01

This study identifies the conceptual underpinnings of effective school-based drug education practice in light of contemporary research evidence and the practical experience of a broad range of drug education stakeholders. The research involved a review of the literature, a national survey of 210 Australian teachers and others involved in drug education, and structured interviews with 22 key Australian drug education policy stakeholders. The findings from this research have been distilled and presented as a list of 16 principles that underpin effective drug education. In broad terms, drug education should be evidence-based, developmentally appropriate, sequential, and contextual. Programs should be initiated before drug use commences. Strategies should be linked to goals and should incorporate harm minimization. Teaching should be interactive and use peer leaders. The role of the classroom teacher is central. Certain program content is important, as is social and resistance skills training. Community values, the social context of use, and the nature of drug harm have to be addressed. Coverage needs to be adequate and supported by follow-up. It is envisaged that these principles will provide all those involved in the drug education field with a set of up-to-date, research-based guidelines against which to reference decisions on program design, selection, implementation, and evaluation.

Application of economic principles in healthcare priority setting.

Science.gov (United States)

Bate, Angela; Mitton, Craig

2006-06-01

In healthcare, resources are often insufficient to meet all claims on them. In this respect, resources are considered scarce and have to be managed by prioritizing between competing claims. Economics as a discipline explicitly addresses this reality by acknowledging resource scarcity. However, the extent to which economics actually influences such prioritizing decisions in healthcare is unclear. The purpose of this paper is to review the use of economics in priority setting decision making. We outline the key principles of economics as they apply to priority setting and review the methods reported in the literature with respect to these. We find that these methods, even economic methods (e.g., those typically used in conducting economic evaluations such as cost-effectiveness analyses) do not tend to explicitly incorporate economic principles. We argue therefore that these methods, when applied to the context of priority setting, are not sufficient and that what is required is a broader framework that can incorporate the output from economic methods yet also be pragmatically applicable. We then go on to present an alternative approach - namely program budgeting and marginal analysis. Finally, we put forward our case for using program budgeting and marginal analysis in priority setting practice and set out some future research challenges.

Challenges in applying the ACPO principles in cloud forensic investigations

2012-03-01

Full Text Available The numerous advantages offered by cloud computing has fuelled its growth and has made it one of the most significant of current computing trends. The same advantages have created complex issues for those conducting digital forensic investigations. Digital forensic investigators rely on the ACPO guidelines when conducting an investigation, however the guidelines make no reference to some of the issues presented by cloud investigations.This study investigates the impact of cloud computing on ACPO’s core principles and asks whether there is a need for the principles and guidelines to be reviewed to address the issues presented by cloud computing. Empirical research is conducted and data collected from key experts in the field of digital forensics.This research presents several key findings: there is a very real concern for how cloud computing will affect digital forensic investigations; the ACPO principles cannot easily be applied in all cloud investigations but are generally sufficient for cloud computing forensic investigations. However the advent of cloud computing is a significant development in technology and may in the near future warrant a review of the guidelines in particular to incorporate the involvement of third parties in cloud investigations.

The precautionary principle: is it safe.

Gignon, Maxime; Ganry, Olivier; Jardé, Olivier; Manaouil, Cécile

The precautionary principle is generally acknowledged to be a powerful tool for protecting health but it was originally invoked by policy makers for dealing with environmental issues. In the 1990s, the principle was incorporated into many legislative and regulatory texts in international law. One can consider that the precautionary principle has turned into "precautionism" necessary to prove to the people, taking account of risk in decisions. There is now a risk that these abuses will deprive the principle of its meaning and value. When pushed to its limits, the precautionary principle can even be dangerous when applied to the healthcare field. This is why a critical analysis of the principle is necessary. Through the literature, it sometimes seems to deviate somehow from the essence of the precautionary principle as it is commonly used in relation to health. We believe that educational work is necessary to familiarize professionals, policy makers and public opinion of the precautionary principle and avoid confusion. We propose a critical analysis of the use and misuse of the precautionary principle.

Cluster-randomized Studies in Educational Research: Principles and Methodological Aspects

Dreyhaupt, Jens

2017-05-01

Full Text Available An increasing number of studies are being performed in educational research to evaluate new teaching methods and approaches. These studies could be performed more efficiently and deliver more convincing results if they more strictly applied and complied with recognized standards of scientific studies. Such an approach could substantially increase the quality in particular of prospective, two-arm (intervention studies that aim to compare two different teaching methods. A key standard in such studies is randomization, which can minimize systematic bias in study findings; such bias may result if the two study arms are not structurally equivalent. If possible, educational research studies should also achieve this standard, although this is not yet generally the case. Some difficulties and concerns exist, particularly regarding organizational and methodological aspects. An important point to consider in educational research studies is that usually individuals cannot be randomized, because of the teaching situation, and instead whole groups have to be randomized (so-called “cluster randomization”. Compared with studies with individual randomization, studies with cluster randomization normally require (significantly larger sample sizes and more complex methods for calculating sample size. Furthermore, cluster-randomized studies require more complex methods for statistical analysis. The consequence of the above is that a competent expert with respective special knowledge needs to be involved in all phases of cluster-randomized studies.Studies to evaluate new teaching methods need to make greater use of randomization in order to achieve scientifically convincing results. Therefore, in this article we describe the general principles of cluster randomization and how to implement these principles, and we also outline practical aspects of using cluster randomization in prospective, two-arm comparative educational research studies.

Sanders, Nathan E.; Kohler, Susanna; Faesi, Chris; Villar, Ashley; Zevin, Michael

2017-10-01

A primary goal of many undergraduate- and graduate-level courses in the physical sciences is to prepare students to engage in scientific research or to prepare students for careers that leverage skillsets similar to those used by research scientists. Even for students who may not intend to pursue a career with these characteristics, exposure to the context of applications in modern research can be a valuable tool for teaching and learning. However, a persistent barrier to student participation in research is familiarity with the technical language, format, and context that academic researchers use to communicate research methods and findings with each other: the literature of the field. Astrobites, an online web resource authored by graduate students, has published brief and accessible summaries of more than 1300 articles from the astrophysical literature since its founding in 2010. This article presents three methods for introducing students at all levels within the formal higher education setting to approaches and results from modern research. For each method, we provide a sample lesson plan that integrates content and principles from Astrobites, including step-by-step instructions for instructors, suggestions for adapting the lesson to different class levels across the undergraduate and graduate spectrum, sample student handouts, and a grading rubric.

This article will demonstrate how the Royal College of Nursing's (RCN's) Principles of Nursing Practice (2010) and the 6Cs (Cummings and Bennett, 2012a ; 2012b) can be applied to stoma care nursing. The multidimensional role of the stoma care nurse means that he or she is well placed to improve quality and standards in stoma nursing care. Stoma care nurses provide direct patient care and can play a vital part in helping patients with a stoma, a long-term condition, ensuring that their patients get the best possible care (RCN, 2010). The poster contained within this article was displayed at the Association of Stoma Care Nurses (ASCN) national conference in Harrogate in October 2014 and was voted the overall winner. The authors of the article and the poster are stoma care nurses working in the acute and community settings and, between 2013 and 2014, they completed the RCN's Clinical Leadership Programme (RCN, 2005). The NHS Plan (Department of Health, 2000) identified the importance of leadership and the necessity of remodelling the NHS around the needs of service users. With this in mind, using the Principles of Nursing Practice and the 6Cs within stoma care demonstrates development with a consistent focus on patient care.

Secret, Mary; Abell, Melissa L; Berlin, Trey

2011-01-01

The authors present a set of guiding principles and strategies to facilitate the collaborative efforts of social work researchers and practitioners as they initiate, design, and implement outcome evaluations of human service interventions and programs. Beginning with an exploration of the interpersonal barriers to practice-research collaborations, and building on their experiences in successfully completing a community-based research evaluation, the authors identify specific relationship-focused principles and strategies and illustrate how these approaches can guide practice-research teams through the various sequential activities of the evaluation research process. In particular, it is suggested that practice-research collaborations can be formed, strengthened, and sustained by emphasis on a spirit of discovery and shared leadership at the start of the relationship, use of a comprehensive evaluation model to clarify and frame the evaluation and program goals, beginning where the client is when selecting research methodology and measurement tools, commitment to keeping the program first and recording everything during the implementation and data-collection stages, discussion of emerging findings and presentation of findings in graphic format at the data-analysis stage, and a total team approach at the dissemination stage.

2013-01-01

Programmatic changes for the dermatology residency program at The University of Texas Medical Branch were first introduced in 2005, with the faculty goal incorporating formal dermatology research projects into the 3-year postgraduate training period. This curriculum initially developed as a recommendation for voluntary scholarly project activity by residents, but it evolved into a program requirement for all residents in 2009. Departmental support for this activity includes assignment of a faculty mentor with similar interest about the research topic, financial support from the department for needed supplies, materials, and statistical consultation with the Office of Biostatistics for study design and data analysis, a 2-week elective that provides protected time from clinical activities for the purpose of preparing research for publication and submission to a peer-reviewed medical journal, and a departmental award in recognition for the best resident scholarly project each year. Since the inception of this program, five classes have graduated a total of 16 residents. Ten residents submitted their research studies for peer review and published their scholarly projects in seven dermatology journals through the current academic year. These articles included three prospective investigations, three surveys, one article related to dermatology education, one retrospective chart review, one case series, and one article about dermatopathology. An additional article from a 2012 graduate about dermatology education has also been submitted to a journal. This new program for residents was adapted from our historically successful Dermatology Honors Research Program for medical students at The University of Texas Medical Branch. Our experience with this academic initiative to promote dermatology research by residents is outlined. It is recommended that additional residency programs should consider adopting similar research programs to enrich resident education. PMID:23901305

B&W Y-12 is committed to modernizing the Y-12 complex to meet future needs with a sustainable and responsive infrastructure and to integrating sustainability principles and practices into Y-12 work (Y72-001, B&W Y-12 Environmental, Safety and Health Policy). This commitment to sustainability and specifically sustainable design of buildings is also incorporated into Presidential Executive Orders (EO), DOE Orders (DOE O), and goals. Sustainable building design is an approach to design, construct, and operate facilities in an efficient and environmentally sound manner that will produce a healthful, resource-efficient and productive working environment that is inherently protective of the environment. The DOE has established the following 5 Guiding Principles for High Performance Sustainable Building (HPSB), and has issued directives that require Y-12 to incorporate the principles and a number of supporting specific practices and techniques into building design, construction and renovation projects: (1) Employ Integrated Design Principles; (2) Optimize Energy Performance; (3) Protect and Conserve Water; (4) Enhance Indoor Environmental Quality; and (5) Reduce Environmental Impact of Materials. The purpose of this document is to present the required sustainable building principles, practices and techniques, summarize the key drivers for incorporating them into Y-12 projects, and present additional recommendations and resources that can be used to support sustainable buildings to enhance the environmental and economic performance of the Y-12 Complex.

A novel Protocol Ethics Tool Kit ('Ethics Tool Kit') has been developed by a multi-stakeholder group of the Multi-Regional Clinical Trials Center of Brigham and Women's Hospital and Harvard. The purpose of the Ethics Tool Kit is to facilitate effective recognition, consideration and deliberation of critical ethical issues in clinical trial protocols. The Ethics Tool Kit may be used by investigators and sponsors to develop a dedicated Ethics Section within a protocol to improve the consistency and transparency between clinical trial protocols and research ethics committee reviews. It may also streamline ethics review and may facilitate and expedite the review process by anticipating the concerns of ethics committee reviewers. Specific attention was given to issues arising in multinational settings. With the use of this Tool Kit, researchers have the opportunity to address critical research ethics issues proactively, potentially speeding the time and easing the process to final protocol approval.

The validity of the extended energy principle

International Nuclear Information System (INIS)

Chance, M.S.; Johnson, J.L.; Kulsrud, R.M.

1994-04-01

A recent analysis of plasma stability based on modifications of the extended energy principle for magnetohydrodynamic stability led to conclusions that are too optimistic. The original interpretation of this principle is indeed applicable. The present analysis demonstrates explicitly the fallacy of using the wrong functional for δW in the extended energy principle. It then shows that the original energy principle functional δW B is also obtained for a model in which a surface mass is incorporated to provide pressure balance. This work therefore indicates, but does not prove, that the eigenfunctions that are obtained from a minimization of the extended energy principle with the proper kinetic energy norm provide a good representation of what would be achieved with an exact treatment

Joint principles: Integrating behavioral health care into the patient-centered medical home.

Science.gov (United States)

2014-06-01

The Patient-centered Medical Home (PCMH) is an innovative, improved, and evolving approach to providing primary care that has gained broad acceptance in the United States. The Joint Principles of the PCMH, formulated and endorsed in February 2007, are sound and describe the ideal toward which we aspire. However, there is an element running implicitly through these joint principles that is difficult to achieve yet indispensable to the success of the entire PCMH concept. The incorporation of behavioral health care has not always been included as practices transform to accommodate to the PCMH ideals. This is an alarming development because the PCMH will be incomplete and ineffective without the full incorporation of this element, and retrofitting will be much more difficult than prospectively integrating into the original design of the PCMH. Therefore we offer a complementary set of joint principles that recognizes the centrality of behavioral health care as part of the PCMH. This document follows the order and language of the original joint principles while emphasizing what needs to be addressed to insure incorporation of the essential behavioral elements. It is intended to supplement and not replace the original Joint Principles document, which still stands.

Bioethical Principles of Biomedical Research Involving Animals

animals for research, testing, or training in different countries. In the few that have done so, the measures adopted vary widely: on the one hand, legally enforceable detailed regulations with licensing of experimenters and their premises together with an official inspectorate; on the other, entirely voluntary self-regulation by the biomedical community, with lay participation. Many variations are possible between these extremes, one intermediate situation being a legal requirement that experiments or other procedures involving the use of animals should be subject to the approval of ethical committees of specified composition.The International Guiding Principles are the product of the collaboration of a representative sample of the international biomedical community, including experts of the World Health Organization, and of consultations with responsible animal welfare groups. The International Guiding Principles have already gained a considerable measure of acceptance internationally. European Medical Research Councils (EMRC, an international association that includes all the West European medical research councils, fully endorsed the Guiding Principles in 1984. Here we bring the basic bioethical principles for using animals in biomedical research[3]: Methods such as mathematical models, computer simulation and in vitro biological systems should be used wherever appropriate,Animal experiments should be undertaken only after due consideration of their relevance for human or animal health and the advancement of biological knowledge,The animals selected for an experiment should be of an appropriate species and quality, and the minimum number required to obtain scientifically valid results,Investigators and other personnel should never fail to treat animals as sentient, and should regard their proper care and use and the avoidance or minimization of discomfort, distress, or pain as ethical imperatives,Procedures with animals that may cause more than momentary or minimal

In 1992 the United Nations Declaration on the Environment stated that where there are threats of serious or irreversible damage, lack of full scientific certainty will not be used as a reason for postponing cost-effective measures to prevent environmental degradation. Since this interpretation has been reaffirmed within numerous framework conventions and national environment law in a number of countries has begun to incorporate it. The contents of the precautionary principle: There are in fact two completely different ideas about the principle: the absolute: the precautionary principle would aim to guarantee complete harmless. The aim is zero risk and even a minimal suspicion of risk should result in a moratorium or a definitive ban, the moderate: its implementation is subject to a scientifically credible statement of hypothetical risk. It also gives priority to positive measures particularly research to provide a better assessment of the risk. In every case, before any decision a statement of cost and of advantages should be drawn up. The concept of prudent avoidance introduced in 1989 by G. Morgan and adopted by some states (Sweden, Australia) seems to be a specific application of the precautionary principle to EMF, taking into account the cost of the policy. The EMF research: After more than 20 years of research (epidemiological residential and professional studies, in vitro studies and laboratory animal studies) the scientific uncertainty has been considerably reduced but the possibility of some adverse effects remains. This fact and the public concern about EMF (partly explained by the ubiquity of exposure) explain the temptations in applying the precautionary principle to the EMF issue

What is the uncertainty principle of non-relativistic quantum mechanics?

Science.gov (United States)

Riggs, Peter J.

2018-05-01

After more than ninety years of discussions over the uncertainty principle, there is still no universal agreement on what the principle states. The Robertson uncertainty relation (incorporating standard deviations) is given as the mathematical expression of the principle in most quantum mechanics textbooks. However, the uncertainty principle is not merely a statement of what any of the several uncertainty relations affirm. It is suggested that a better approach would be to present the uncertainty principle as a statement about the probability distributions of incompatible variables and the resulting restrictions on quantum states.

Ethnographic research with adolescent students: situated fieldwork ethics and ethical principles governing human research.

Science.gov (United States)

Hemmings, Annette

2009-12-01

This paper explores ethical dilemmas in situated fieldwork ethics concerning ethnographic studies of adolescent students. While consequentialist and deontological ethics form the basis of the ethical stances shared by ethnographers and research ethics committees, the interpretation of those principles may diverge in school-based ethnography with adolescent students because of the particular role of the adult ethnographer vis-à-vis developmentally immature adolescents not held legally responsible for many of their actions. School ethnographers attempt to build trust with adolescent participants in order to learn about their hidden cultural worlds, which may involve activities that are very harmful to the youths involved. They face many difficult and sometimes unexpected choices, including whether to intervene and how to represent events and adolescents in published findings. Scenarios with examples drawn from research conducted in public high schools are used to illustrate and explicate dilemmas in formal research and latent insider/outsider roles and relations involving harmful adolescent behaviors, advocacy, and psychological trauma. Also examined are analytical procedures used to construct interpretations leading to representations of research participants in the resulting publication.

The base rate principle and the fairness principle in social judgment.

Cao, Jack; Banaji, Mahzarin R

Meet Jonathan and Elizabeth. One person is a doctor and the other is a nurse. Who is the doctor? When nothing else is known, the base rate principle favors Jonathan to be the doctor and the fairness principle favors both individuals equally. However, when individuating facts reveal who is actually the doctor, base rates and fairness become irrelevant, as the facts make the correct answer clear. In three experiments, explicit and implicit beliefs were measured before and after individuating facts were learned. These facts were either stereotypic (e.g., Jonathan is the doctor, Elizabeth is the nurse) or counterstereotypic (e.g., Elizabeth is the doctor, Jonathan is the nurse). Results showed that before individuating facts were learned, explicit beliefs followed the fairness principle, whereas implicit beliefs followed the base rate principle. After individuating facts were learned, explicit beliefs correctly aligned with stereotypic and counterstereotypic facts. Implicit beliefs, however, were immune to counterstereotypic facts and continued to follow the base rate principle. Having established the robustness and generality of these results, a fourth experiment verified that gender stereotypes played a causal role: when both individuals were male, explicit and implicit beliefs alike correctly converged with individuating facts. Taken together, these experiments demonstrate that explicit beliefs uphold fairness and incorporate obvious and relevant facts, but implicit beliefs uphold base rates and appear relatively impervious to counterstereotypic facts.

Using community-based participatory research principles to develop more understandable recruitment and informed consent documents in genomic research.

Full Text Available Heart Healthy Lenoir is a transdisciplinary project aimed at creating long-term, sustainable approaches to reduce cardiovascular disease risk disparities in Lenoir County, North Carolina using a design spanning genomic analysis and clinical intervention. We hypothesized that residents of Lenoir County would be unfamiliar and mistrustful of genomic research, and therefore reluctant to participate; additionally, these feelings would be higher in African-Americans.To test our hypothesis, we conducted qualitative research using community-based participatory research principles to ensure our genomic research strategies addressed the needs, priorities, and concerns of the community. African-American (n = 19 and White (n = 16 adults in Lenoir County participated in four focus groups exploring perceptions about genomics and cardiovascular disease. Demographic surveys were administered and a semi-structured interview guide was used to facilitate discussions. The discussions were digitally recorded, transcribed verbatim, and analyzed in ATLAS.ti.From our analysis, key themes emerged: transparent communication, privacy, participation incentives and barriers, knowledge, and the impact of knowing. African-Americans were more concerned about privacy and community impact compared to Whites, however, African-Americans were still eager to participate in our genomic research project. The results from our formative study were used to improve the informed consent and recruitment processes by: 1 reducing misconceptions of genomic studies; and 2 helping to foster participant understanding and trust with the researchers. Our study demonstrates how community-based participatory research principles can be used to gain deeper insight into the community and increase participation in genomic research studies. Due in part to these efforts 80.3% of eligible African-American participants and 86.9% of eligible White participants enrolled in the Heart Healthy Lenoir Genomics

Technological advances in the quality, availability and linkage potential of health data for research make the need to develop robust and effective information governance mechanisms more pressing than ever before; they also lead us to question the utility of governance devices used hitherto such as consent and anonymisation. This article assesses and advocates a principles-based approach, contrasting this with traditional rule-based approaches, and proposes a model of principled proportionate governance . It is suggested that the approach not only serves as the basis for good governance in contemporary data linkage but also that it provides a platform to assess legal reforms such as the draft Data Protection Regulation.

General principles of nuclear safety management related to research reactor decommissioning

International Nuclear Information System (INIS)

Banciu, Ortenzia; Vladescu, Gabriela

2003-01-01

The paper contents the general principles applicable to the decommissioning of research reactors to ensure a proper nuclear safety management, during both decommissioning activities and post decommissioning period. The main objective of decommissioning is to ensure the protection of workers, population and environment against all radiological and non-radiological hazards that could result after a reactor shutdown and dismantling. In the same time, it is necessary, by some proper provisions, to limit the effect of decommissioning for the future generation, according to the new Romanian, IAEA and EU Norms and Regulations. Assurance of nuclear safety during decommissioning process involves, in the first step, to establish of some safety principles and requirements to be taken into account during whole process. In the same time, it is necessary to perform a series of analyses to ensure that the whole process is conducted in a planned and safe manner. The general principles proposed for a proper management of safety during research reactor decommissioning are as follows: - Set-up of all operations included in a Decommissioning Plan; - Set-up and qualitative evaluation of safety problems, which could appear during normal decommissioning process, both radiological and nonradiological risks for workers and public; - Set-up of accident list related to decommissioning process the events that could appear both due to some abnormal working conditions and to some on-site and off-site events like fires, explosions, flooding, earthquake, etc.); - Development and qualitative/ quantitative evaluation of scenarios for each incidents; - Development (and evaluation) of safety indicator system. The safety indicators are the most important tools used to assess the level of nuclear safety during decommissioning process, to discover the weak points and to establish safety measures. The paper contains also, a safety case evaluation (description of facility according to the decommissioning

Neal, L J

1999-01-01

A grounded-theory study of 30 home health nurses conducted in the Washington, DC, metropolitan area used unstructured audiotaped interviews to elicit data as to how home health nurses define their practice. The purpose of the study was to develop a beginning substantive research-based theory of home health nursing practice. The model that emerged consists of three stages by which nurses attain autonomy in their practice. Adaptation was found to be the core category, in that nurses cannot function effectively or successfully in the home health arena unless they are or learn to be adaptable. Data also revealed that home health nurses either knowingly or unknowingly use rehabilitation nursing principles in their practice, thereby lending credence to the supposition that home health nursing practice is congruent with rehabilitation nursing principles.

Psychometric Principles in Measurement for Geoscience Education Research: A Climate Change Example

Science.gov (United States)

Libarkin, J. C.; Gold, A. U.; Harris, S. E.; McNeal, K.; Bowles, R.

2015-12-01

Understanding learning in geoscience classrooms requires that we use valid and reliable instruments aligned with intended learning outcomes. Nearly one hundred instruments assessing conceptual understanding in undergraduate science and engineering classrooms (often called concept inventories) have been published and are actively being used to investigate learning. The techniques used to develop these instruments vary widely, often with little attention to psychometric principles of measurement. This paper will discuss the importance of using psychometric principles to design, evaluate, and revise research instruments, with particular attention to the validity and reliability steps that must be undertaken to ensure that research instruments are providing meaningful measurement. An example from a climate change inventory developed by the authors will be used to exemplify the importance of validity and reliability, including the value of item response theory for instrument development. A 24-item instrument was developed based on published items, conceptions research, and instructor experience. Rasch analysis of over 1000 responses provided evidence for the removal of 5 items for misfit and one item for potential bias as measured via differential item functioning. The resulting 18-item instrument can be considered a valid and reliable measure based on pre- and post-implementation metrics. Consideration of the relationship between respondent demographics and concept inventory scores provides unique insight into the relationship between gender, religiosity, values and climate change understanding.

Involving older people in research: practical considerations when using the authenticity criteria in constructivist inquiry

Science.gov (United States)

Wilson, Christine Brown; Clissett, Philip

2011-01-01

Aim The purpose of this paper is to identify practical suggestions that could enable other researchers to consider how quality may be evidenced using constructivist principles including the perspectives of older people and their caregivers. Background Constructivism suggests that reality is part of a social construction, which holds different meanings for each person, in which people are active agents, making autonomous decisions. This approach to research has been identified as suitable for health and social care professionals because these underpinning principles reflect the values of these professions, facilitating the involvement of users and carers. The authenticity criteria have been developed to reflect these philosophical principles but have been criticized for their inaccessible language. To incorporate user and carer perspectives, the criteria have been revised into a more accessible model matrix known as the AldreVast Sjuharad criteria. Discussion This paper reports on two constructivist studies that explored relationships between older people, families and staff in different settings – the community and care homes. Examples from both settings demonstrate how the perspectives of users and carers were incorporated throughout the research process. Following the AldreVast Sjuharad model matrix, practical guidance is provided on how the quality of constructivist research may be implemented in nursing research. Conclusions The different settings in this paper influenced how the AldreVast Sjuharad model matrix was applied. Further work is needed in exploring how the perspective of users and carers may be incorporated into the quality process of constructivist research. PMID:21073505

Handicap principle implies emergence of dimorphic ornaments.

Clifton, Sara M; Braun, Rosemary I; Abrams, Daniel M

2016-11-30

Species spanning the animal kingdom have evolved extravagant and costly ornaments to attract mating partners. Zahavi's handicap principle offers an elegant explanation for this: ornaments signal individual quality, and must be costly to ensure honest signalling, making mate selection more efficient. Here, we incorporate the assumptions of the handicap principle into a mathematical model and show that they are sufficient to explain the heretofore puzzling observation of bimodally distributed ornament sizes in a variety of species. © 2016 The Author(s).

Principles of (Behavioral) Economics

Behavioral economics has become an important and integrated component of modern economics. Behavioral economists embrace the core principles of economics—optimization and equilibrium—and seek to develop and extend those ideas to make them more empirically accurate. Behavioral models assume that economic actors try to pick the best feasible option and those actors sometimes make mistakes. Behavioral ideas should be incorporated throughout the first-year undergraduate course. Instructors should...

Tuning the work function of VO_2(1 0 0) surface by Ag adsorption and incorporation: Insights from first-principles calculations

International Nuclear Information System (INIS)

Chen, Lanli; Wang, Xiaofang; Shi, Siqi; Cui, Yuanyuan; Luo, Hongjie; Gao, Yanfeng

2016-01-01

Graphical abstract: - Highlights: • After adsorption, there is a charge transfer from Ag to VO_2(1 0 0) surface, which thus increases the electron concentration in VO_2 thin film. • Ag adsorption on VO_2(1 0 0) surface process is an exothermic chemical process, and the adsorption system is stable. • The work function can be tuned by Ag adsorption on and incorporation into the VO_2(1 0 0) surface, which in turn regulates the phase transition temperature of VO_2. - Abstract: VO_2 is an attractive material for application to thermochromic optoelectronic devices such as smart windows, and Ag/VO_2 double-layered structure can effectively decrease the phase transition temperature (T_c) of VO_2 thin film, which is very important for practical application of VO_2. Previous works has shown that the decrease in phase transition temperature (T_c) seems to be relevant with the work function of VO_2 in Ag/VO_2 double-layered thin film, although the underlying mechanism of tuning its T_c by Ag incorporation and adsorption on the VO_2(1 0 0) surface has been rarely investigated. Our first-principles calculations reveal that the adsorption of Ag atoms on the VO_2(1 0 0) surface rather than incorporation of Ag exhibits a lower work function, which is ascribed to an integrated effect of charge transfer from Ag to VO_2(1 0 0) surface and enhanced surface dipole moment. The results suggest that the decrease in work function of VO_2 with Ag adsorption favors the reduction in T_c. The current findings are helpful to understand the fundamental mechanism for yielding high-efficiency VO_2-based optoelectronic devices.

Gentles, Stephen J; Charles, Cathy; Nicholas, David B; Ploeg, Jenny; McKibbon, K Ann

2016-10-11

Overviews of methods are potentially useful means to increase clarity and enhance collective understanding of specific methods topics that may be characterized by ambiguity, inconsistency, or a lack of comprehensiveness. This type of review represents a distinct literature synthesis method, although to date, its methodology remains relatively undeveloped despite several aspects that demand unique review procedures. The purpose of this paper is to initiate discussion about what a rigorous systematic approach to reviews of methods, referred to here as systematic methods overviews, might look like by providing tentative suggestions for approaching specific challenges likely to be encountered. The guidance offered here was derived from experience conducting a systematic methods overview on the topic of sampling in qualitative research. The guidance is organized into several principles that highlight specific objectives for this type of review given the common challenges that must be overcome to achieve them. Optional strategies for achieving each principle are also proposed, along with discussion of how they were successfully implemented in the overview on sampling. We describe seven paired principles and strategies that address the following aspects: delimiting the initial set of publications to consider, searching beyond standard bibliographic databases, searching without the availability of relevant metadata, selecting publications on purposeful conceptual grounds, defining concepts and other information to abstract iteratively, accounting for inconsistent terminology used to describe specific methods topics, and generating rigorous verifiable analytic interpretations. Since a broad aim in systematic methods overviews is to describe and interpret the relevant literature in qualitative terms, we suggest that iterative decision making at various stages of the review process, and a rigorous qualitative approach to analysis are necessary features of this review type

A new method to incorporate the Pauli principle into the double folding approach to the heavy ion potential is proposed. It is shown that in order to take into account the Pauli blocking a redefinition of the density matrices of the free isolated nuclei must be one. A solution to the self-consistent incorporation of the Pauli-blocking effects in the mean-field nucleus-nucleus potential is obtained in the Thomas-Fermi approximation [ru

Action principles for the Vlasov equation

International Nuclear Information System (INIS)

Ye, H.; Morrison, P.J.

1992-01-01

Five action principles for the Vlasov--Poisson and Vlasov--Maxwell equations, which differ by the variables incorporated to describe the distribution of particles in phase space, are presented. Three action principles previously known for the Vlasov--Maxwell equations are altered so as to produce the Vlasov--Poisson equation upon variation with respect to only the particle variables, and one action principle previously known for the Vlasov--Poisson equation is altered to produce the Vlasov--Maxwell equations upon variations with respect to particle and field variables independently. Also, a new action principle for both systems, which is called the leaf action, is presented. This new action has the desirable features of using only a single generating function as the dynamical variable for describing the particle distribution, and manifestly preserving invariants of the system known as Casimir invariants. The relationships between the various actions are described, and it is shown that the leaf action is a link between actions written in terms of Lagrangian and Eulerian variables

2018-02-01

Open innovation has become the main trend in pharmaceutical research. Potential obstacles and pitfalls of collaborations often lead to missed opportunities and/or poorly executed partnerships. This paper aims to provide a framework that facilitates the execution of successful collaborations. We start by mapping out three checkpoints onto early-stage collaborative partnerships: inception, ignition and implementation. Different value types and value drivers are then laid out for each phase of the partnership. We proceed to propose a ratio-driven approach and a value-adjustment mechanism, enhancing the probability of successes in pharmaceutical research collaborations. These guiding principles combined should help the partners either reach agreement more quickly or move on to the next potential project. Copyright © 2017 Elsevier Ltd. All rights reserved.

Nurses sometimes lack the competence needed for recognising deterioration in patient conditions and this is often due to poor clinical reasoning. There is a need to develop new possibilities for learning this crucial competence area. In addition, educators need to be future oriented; they need to be able to design and adopt new pedagogical innovations. The purpose of the study is to describe the development process and to generate principles for the design of nursing simulation games. A design-based research methodology is applied in this study. Iterative cycles of analysis, design, development, testing and refinement were conducted via collaboration among researchers, educators, students, and game designers. The study facilitated the generation of reusable design principles for simulation games to guide future designers when designing and developing simulation games for learning clinical reasoning. This study makes a major contribution to research on simulation game development in the field of nursing education. The results of this study provide important insights into the significance of involving nurse educators in the design and development process of educational simulation games for the purpose of nursing education.

Between Economic and Legal Analysis of Incorporated Things: a Critical "NO" to Aedilitian Remedies

Directory of Open Access Journals (Sweden)

CG Kilian

2006-01-01

Full Text Available This article analyses the dictum of the Phame v Paizes 1973 3 397 (A within economic and legal principles to determine whether incorporeal things could possess characteristics of value or quality characteristics as in the case of corporeal things. The author uses practical economic examples to argue for the development of common law. The author identifies relevant Roman law principles which justify the legal nature of incorporeal things. It is demonstrated that the value of incorporeal things depends greatly on future circumstances. It is argued in this article that the courts’ willingness to extend the Aedilitian remedies and the wide interpretation of a dictum et promissum create an open door for any unsatisfied buyer with no entrepreneurial skills to claim a reduced price if the business is unable to achieve similar financial results to those prior to the conclusion of the contract. Currently the seller of a business has no clear or enforceable defense under these circumstances. The author subsequently suggests that relevant Roman law principles should be revisited in the aim to develop an appropriate defense for the seller.

A first principles study of energetics and electronic structural responses of uranium-based coordination polymers to Np incorporation

Recently developed coordination polymers (CPs) and metal organic frameworks (MOFs) may find applications in areas such as catalysis, hydrogen storage, and heavy metal immobilization. Research on the potential application of actinide-based CPs (An-CP/MOFs) is not as advanced as transition metal-based MOFs. In order to modify their structures necessary for optimizing thermodynamic and electronic properties, here, we described how a specific topology of a particular actinide-based CP or MOF responds to the incorporation of other actinides considering their diverse coordination chemistry associated with the multiple valence states and charge-balancing mechanisms. In this study, we apply a recently developed DFT-based method to determine the relative stability of transuranium incorporated CPs in comparison to their uranium counterpart considering both solid and aqueous state sources and sinks to understand the mechanism and energetics of charge-balanced Np{sup 5+} incorporation into three uranium-based CPs. The calculated Np{sup 5+} + H{sup +} incorporation energies for these CPs range from 0.33 to 0.52 eV, depending on the organic linker, when using the solid oxide Np source Np{sub 2}O{sub 5} and U sink UO{sub 3}. Incorporation energies of these CPs using aqueous sources and sinks increase to 2.85-3.14 eV. The thermodynamic and structural analysis in this study aides in determining, why certain MOF topologies and ligands are selective for some actinides and not for others. This means that once this method is extended across a variety of CPs with their respective linker molecules and different actinides, it can be used to identify certain CPs with certain organic ligands being specific for certain actinides. This information can be used to construct CPs for actinide separation. This is the first determination of the electronic structure (band structure, density of states) of these uranium- and transuranium-based CPs which may eventually lead to design CPs with certain

Incorporating sustainable development principles in the governance of Dutch domestic tourism. The relevance of boundary judgments

Energy Technology Data Exchange (ETDEWEB)

Bressers, H.; Dinica, V.

2008-08-14

This research is an exploratory investigation into factors responsible for the inadequate incorporation of sustainable development principles into governance of Dutch domestic tourism. The research methodology of the study from which this paper originates consists of: literature and document analysis; 27 in-depth interviews with political (parliament members), public (ministries, provincial authorities, IPO, VNG), commercial, knowledge and NGO actors; and a survey of perceptions, governance preferences and values by means of a questionnaire returned by 44 respondents in all the above actor-categories. This paper is mainly based on that survey, but against the background of the findings of the other parts of the study. These findings were that governance innovations for sustainability have been so far limited and symbolic. There is a mismatch between the UNEP-WTO recommendations and how the Dutch tourism governance looks like. The approach to decentralization chosen in the country and the thematic rather than sectoral organization of policies makes it difficult to implement many UNEP-WTO recommendations on governance structure features. A policy gap emerged under decentralization, as three-quarters of municipalities do not have tourism policies, allowing for uncontrolled unsustainable developments. There is no problem owner for sustainable tourism. The general public and many organizations have a very low problem perception. Ministries explicitly point to each other and sub-national authorities. Likewise the association of sub-national authorities points to the ministries. Most commercial tourism actors are not interested in sustainability beyond the economic and (client/worker) security dimensions. While sustainability is 'hot' and tourism is 'booming', sustainable tourism is clearly 'low politics'. In the absence of public debate, changing such situation is dependent on the opinions of people inside stakeholder organizations. The

CORPORATE GOVERNANCE-THE ROLE AND APPLICATION OF THE PRINCIPLE OF TRANSPARENCY

Directory of Open Access Journals (Sweden)

Fulop Melinda Timea

2011-07-01

Full Text Available The aim of the current research is to clarify the concept of corporate governance as we believe it is a relatively new concept at national level. At the same time, our analysis focused on the manner in which the principle of transparency has been incorporated into the recommendations and regulations/provisions of the Bucharest Stock Exchange (Romanian: BVB and how this principle has been applied by the companies listed with the BVB. In order to accomplish the objectives of our research, we adopted a deductive approach, from general to specific, by means of which we were able to combine qualitative with quantitative studies. Therefore, our approach started from the definition found within the principles of OECD according to which corporate governance is the system by which companies are run and controlled. In Romania, the concept of corporate governance was first advanced in 1999 by the Strategic Alliance of the Business Associations (Romanian: ASAA, which drew up a Voluntary code of corporate governance in association with the Confederation of Private Entrepreneurs in Timis county and the Chamber of Commerce and Industry of Romania and Bucharest. Another facet of our research is the principle of transparency and the manner in which entities should put it to practice in order to ensure efficient corporate governance. To this effect, since the beginning of 2009 the entities listed with the BVB have been under obligation to report which recommendations of the new Corporate Governance Code have actually been implemented by the company in the current financial year by disclosing to BVB the Comply or Explain Statement. The findings of our research show that the concept of corporate governance has lately been a matter for intense debate due to the famous financial failures in recent years. In 2009, Transelectrica was the only company in tier I of the BVB which filled in and submitted the Comply or Explain Statement. Therefore, we believe that

Graphical abstract: - Highlights: • After adsorption, there is a charge transfer from Ag to VO{sub 2}(1 0 0) surface, which thus increases the electron concentration in VO{sub 2} thin film. • Ag adsorption on VO{sub 2}(1 0 0) surface process is an exothermic chemical process, and the adsorption system is stable. • The work function can be tuned by Ag adsorption on and incorporation into the VO{sub 2}(1 0 0) surface, which in turn regulates the phase transition temperature of VO{sub 2}. - Abstract: VO{sub 2} is an attractive material for application to thermochromic optoelectronic devices such as smart windows, and Ag/VO{sub 2} double-layered structure can effectively decrease the phase transition temperature (T{sub c}) of VO{sub 2} thin film, which is very important for practical application of VO{sub 2}. Previous works has shown that the decrease in phase transition temperature (T{sub c}) seems to be relevant with the work function of VO{sub 2} in Ag/VO{sub 2} double-layered thin film, although the underlying mechanism of tuning its T{sub c} by Ag incorporation and adsorption on the VO{sub 2}(1 0 0) surface has been rarely investigated. Our first-principles calculations reveal that the adsorption of Ag atoms on the VO{sub 2}(1 0 0) surface rather than incorporation of Ag exhibits a lower work function, which is ascribed to an integrated effect of charge transfer from Ag to VO{sub 2}(1 0 0) surface and enhanced surface dipole moment. The results suggest that the decrease in work function of VO{sub 2} with Ag adsorption favors the reduction in T{sub c}. The current findings are helpful to understand the fundamental mechanism for yielding high-efficiency VO{sub 2}-based optoelectronic devices.

Physical Principle for Generation of Randomness

Science.gov (United States)

Zak, Michail

2009-01-01

A physical principle (more precisely, a principle that incorporates mathematical models used in physics) has been conceived as the basis of a method of generating randomness in Monte Carlo simulations. The principle eliminates the need for conventional random-number generators. The Monte Carlo simulation method is among the most powerful computational methods for solving high-dimensional problems in physics, chemistry, economics, and information processing. The Monte Carlo simulation method is especially effective for solving problems in which computational complexity increases exponentially with dimensionality. The main advantage of the Monte Carlo simulation method over other methods is that the demand on computational resources becomes independent of dimensionality. As augmented by the present principle, the Monte Carlo simulation method becomes an even more powerful computational method that is especially useful for solving problems associated with dynamics of fluids, planning, scheduling, and combinatorial optimization. The present principle is based on coupling of dynamical equations with the corresponding Liouville equation. The randomness is generated by non-Lipschitz instability of dynamics triggered and controlled by feedback from the Liouville equation. (In non-Lipschitz dynamics, the derivatives of solutions of the dynamical equations are not required to be bounded.)

2015-09-30

Have you noticed when you browse a book, journal, study report, or product label how your eye is drawn to figures more than to words and tables? Statistical graphs are powerful ways to transparently and succinctly communicate the key points of medical research. Furthermore, the graphic design itself adds to the clarity of the messages in the data. The goal of this paper is to provide a mechanism for selecting the appropriate graph to thoughtfully construct quality deliverables using good graphic design principles. Examples are motivated by the efforts of a Safety Graphics Working Group that consisted of scientists from the pharmaceutical industry, Food and Drug Administration, and academic institutions.

2016-01-01

In this paper, we explore the quantum spacetimes that are potentially connected with the generalized uncertainty principles. By analyzing the gravity-induced quantum interference pattern and the Gedanken for weighting photon, we find that the generalized uncertainty principles inspire the effective Newton constant as same as our previous proposal. A characteristic momentum associated with the tidal effect is suggested, which incorporates the quantum effect with the geometric nature of gravity...

Using Simulation in Nursing PhD Education: Facilitating Application of Responsible Conduct of Research Principles.

Science.gov (United States)

Clayton, Margaret F; Supiano, Katherine; Wilson, Rebecca; Lassche, Madeline; Latendresse, Gwen

Simulation is a standard clinical nursing educational approach; however, simulation is rarely used in nonclinical nursing education. In doctor of philosophy (PhD) programs, ethical content about responsible conduct of research (RCR) is traditionally didactic, presented early in the program of study. Ethics content merits review before students begin the dissertation phase; thus, the purpose of this project was to design and implement simulated scenarios to help students apply RCR principles prior to beginning independent research. Two scenarios were developed: (a) a potential protocol change discussed in a research team meeting and (b) an in-home data collection experience with an elderly participant and her daughter. Actors were trained faculty volunteers, playing roles outside their usual academic positions. Faculty facilitated scenarios by posing questions as cues related to desired learning outcomes as scenarios unfolded. Eleven nursing PhD students and 6 faculty participated. Debriefing facilitated discussion of RCR principles, common research quandaries, and suggested scenario revisions. Faculty, expert observation, and video-review showed that younger and less experienced students tried to give the "right" answer rather than implement RCR appropriate solutions. Students with more clinical experience had difficulty adopting the less familiar researcher role. Overall, simulation is a novel and useful way to enhance RCR content in PhD programs.

Principled Missing Data Treatments.

Science.gov (United States)

Lang, Kyle M; Little, Todd D

2018-04-01

We review a number of issues regarding missing data treatments for intervention and prevention researchers. Many of the common missing data practices in prevention research are still, unfortunately, ill-advised (e.g., use of listwise and pairwise deletion, insufficient use of auxiliary variables). Our goal is to promote better practice in the handling of missing data. We review the current state of missing data methodology and recent missing data reporting in prevention research. We describe antiquated, ad hoc missing data treatments and discuss their limitations. We discuss two modern, principled missing data treatments: multiple imputation and full information maximum likelihood, and we offer practical tips on how to best employ these methods in prevention research. The principled missing data treatments that we discuss are couched in terms of how they improve causal and statistical inference in the prevention sciences. Our recommendations are firmly grounded in missing data theory and well-validated statistical principles for handling the missing data issues that are ubiquitous in biosocial and prevention research. We augment our broad survey of missing data analysis with references to more exhaustive resources.

A lot of researchers have reported better surgical outcomes and technique innovations facilitated by this novel technology which although in its early stages, it lights up great interest worldwide. This article reviews the principle of the method, the properties of the fluorescent dye, the main clinical applications and discusses future research directions.

Double-folding model including the Pauli exclusion principle

International Nuclear Information System (INIS)

Gridnev, K.A.; Soubbotin, V.B.; Oertzen, W. von; Bohlen, H.G.; Vinas, X.

2002-01-01

A new method for incorporating the Pauli exclusion principle into the double-folding approach to the heavy-ion potential is proposed. The description of the exchange terms at the level of the semiclassical one-body density matrix is used. It is shown that, in order to take into account Pauli blocking properly, the density matrices of free isolated nuclei must be redefined. A solution to the self-consistent incorporation of Pauli blocking effects in the mean-field nucleus-nucleus potential is obtained in the Thomas-Fermi approximation

2011-01-01

We describe the design of the test masses that are used in the 'ground-based principle of equivalence measurement' test of the weak equivalence principle. The main features of the design are the incorporation of corner cubes and the use of mass removal and replacement to create pairs of test masses with different test substances. The corner cubes allow for the vertical separation of the test masses to be measured with picometer accuracy by SAO's unique tracking frequency laser gauge, while the mass removal and replacement operations are arranged so that the test masses incorporating different test substances have nominally identical gravitational properties.

ACCOUNTING PRINCIPLES: EVOLUTION, CONTENT, CONSEQUENCES

Directory of Open Access Journals (Sweden)

Liliana LAZARI

2017-04-01

Full Text Available Accounting principles are rules that help producers of financial information to recognize, evaluate, classify and present information. At the same time, they are very general rules, which can be implemented in several ways, generating more accounting treatments. Although the foreign literature presents numerous classifications of the principles in terms of the given research, we will continue to deal with the terms that have the value of accounting principles, their evolution in the Republic of Moldova, but also the influence on keeping the accounting and financial reporting. In the research, we used the method of comparison, analysis, deduction, but also the historical method. The results of the research on accounting principles will contribute to the development of their applicability both for those studying and researching the field of accounting, as well as for those who apply in practice the keeping of accounting in all stages of work: elaboration of accounting policies, recognition, evaluation and accounting for economic transactions and preparing the financial statements of the entity.

Is three the magic number? The role of ergonomic principles in cross country comprehension of road traffic signs.

Science.gov (United States)

Jamson, Samantha; Mrozek, Marco

2017-07-01

Road sign comprehension plays an important part in road safety management, particularly for those drivers who are travelling in an unfamiliar country. Previous research has established that comprehension can be improved if signs are designed to adhere to ergonomic principles. However, it may be difficult for sign designers to incorporate all the principles into a single sign and may thus have to make a judgement as to the most effective ones. This study surveyed drivers in three countries to ascertain their understanding of a range of road signs, each of which conformed in varying degrees and combinations to the ergonomic principles. We found that using three of the principles was the most effective and that the most important one was that relating to standardisation; the colours and shapes used were key to comprehension. Other concepts which related to physical and spatial characteristics were less important, whilst conceptual compatibility did not aid comprehension at all. Practitioner Summary: This study explores how road sign comprehension can be improved using ergonomic principles, with particular reference to cross-border drivers. It was found that comprehension can be improved significantly if standardisation is adhered to and if at least three principles are used.

With Memoranda and other initiatives, the German Network for Health Service Research [Deutsches Netzwerk Versorgungsforschung e.V. (DNVF)] is fostering the methodological quality of care research studies for years. Compared to the standards of empirical research, questions concerning the role and function of theories, theoretical approaches and scientific principles have not been taken up on its own. Therefore, the DNVF e.V. has set up a working group in 2013, which was commissioned to prepare a memorandum on "theories in health care research". This now presented memorandum will primarily challenge scholars in health care services research to pay more attention to questions concerning the theoretical arsenal and the background assumptions in the research process. The foundation in the philosophy of science, the reference to normative principles and the theory-bases of the research process are addressed. Moreover, the memorandum will call on to advance the theorizing in health services research and to strengthen not empirical approaches, research on basic principles or studies with regard to normative sciences and to incorporate these relevant disciplines in health services research. Research structures and funding of health services research needs more open space for theoretical reflection and for self-observation of their own, multidisciplinary research processes. © Georg Thieme Verlag KG Stuttgart · New York.

Is small violation of the Pauli principle possible?

International Nuclear Information System (INIS)

Ignatiev, A.Yu.; Kuzmin, V.A.

1987-02-01

The Pauli exclusion principle is one of the most fundamental laws of nature. Yet the experiment shows that many fundamental laws are in fact not absolute, but only approximate, i.e. are valid only to a certain accuracy. At present, however, there are no answers to the question: ''To what accuracy is the Pauli principle valid?'' This is so because there are no models capable of describing small deviations from the exclusion principle. In the present paper we consider the problem of constructing such models. We have constructed the simplest algebra of the creation and annihilation operators with a parameter β which incorporates the small violations of the Pauli principle (for β=0 the Pauli principle holds absolutely true). The commutation relations in this model prove to be trilinear. We then present a model Hamiltonian based on the constructed algebra which describes the Pauli principle violating transitions i.e. transitions of two identical particles into the same state with the probability suppressed by a factor of β 2 (notwithstanding the fact that the Hamiltonian itself does not contain any small parameters).

Bartel, B. A.; Morris, A. R.; Charlevoix, D.

2014-12-01

In order to truly broaden the impact of our scientific community, effective communication should be taught alongside research skills to developing scientists. In the summer of 2014, we incorporated an informal communications course into the 10th year of UNAVCO's Research Experiences in Solid Earth Science for Students (RESESS), a year-long internship program centered around an 11-week intensive summer research experience. The goals of the newly designed course included giving students the tools they need to make a broader impact with their science, starting now; improving the students' confidence in public speaking and using social media for outreach; and giving students the tools they need to apply for jobs or graduate school. Specifically, the course included teaching of professional communication skills, such as e-mail and phone etiquette, resume and CV tailoring, and interview techniques, and public communications skills, such as crafting and simplifying messages, visual communication for the public, and public speaking. Student interns were encouraged to step back from the details of their research projects to put their work into a big-picture context relevant to the public and to policy makers. The course benefited from input and/or participation from UNAVCO Education and Community Engagement staff, engineering and managerial staff, and graduate student interns outside the RESESS program, and University of Colorado research and communications mentors already involved in RESESS. As the summer program is already packed with research and skill development, one major challenge was fitting in teaching these communications skills amongst many other obligations: a GRE course, a peer-focused scientific communications course, a computing course, and, of course, research. Can we do it all? This presentation will provide an overview of the course planning, articulation of course goals, and execution challenges and successes. We will present our lessons learned from

Advancing perinatal patient safety through application of safety science principles using health IT.

Webb, Jennifer; Sorensen, Asta; Sommerness, Samantha; Lasater, Beth; Mistry, Kamila; Kahwati, Leila

2017-12-19

The use of health information technology (IT) has been shown to promote patient safety in Labor and Delivery (L&D) units. The use of health IT to apply safety science principles (e.g., standardization) to L&D unit processes may further advance perinatal safety. Semi-structured interviews were conducted with L&D units participating in the Agency for Healthcare Research and Quality's (AHRQ's) Safety Program for Perinatal Care (SPPC) to assess units' experience with program implementation. Analysis of interview transcripts was used to characterize the process and experience of using health IT for applying safety science principles to L&D unit processes. Forty-six L&D units from 10 states completed participation in SPPC program implementation; thirty-two (70%) reported the use of health IT as an enabling strategy for their local implementation. Health IT was used to improve standardization of processes, use of independent checks, and to facilitate learning from defects. L&D units standardized care processes through use of electronic health record (EHR)-based order sets and use of smart pumps and other technology to improve medication safety. Units also standardized EHR documentation, particularly related to electronic fetal monitoring (EFM) and shoulder dystocia. Cognitive aids and tools were integrated into EHR and care workflows to create independent checks such as checklists, risk assessments, and communication handoff tools. Units also used data from EHRs to monitor processes of care to learn from defects. Units experienced several challenges incorporating health IT, including obtaining organization approval, working with their busy IT departments, and retrieving standardized data from health IT systems. Use of health IT played an integral part in the planning and implementation of SPPC for participating L&D units. Use of health IT is an encouraging approach for incorporating safety science principles into care to improve perinatal safety and should be incorporated

This review offers practical recommendations regarding research on training in evidence-based practices for mental health and substance abuse treatment. When designing training research, we recommend: (a) aligning with the larger dissemination and implementation literature to consider contextual variables and clearly defining terminology, (b) critically examining the implicit assumptions underlying the stage model of psychotherapy development, (c) incorporating research methods from other disciplines that embrace the principles of formative evaluation and iterative review, and (d) thinking about how technology can be used to take training to scale throughout all stages of a training research project. An example demonstrates the implementation of these recommendations. PMID:21380792

Foundations of gravitation theory: the principle of equivalence

International Nuclear Information System (INIS)

Haugan, M.P.

1978-01-01

A new framework is presented within which to discuss the principle of equivalence and its experimental tests. The framework incorporates a special structure imposed on the equivalence principle by the principle of energy conservation. This structure includes relations among the conceptual components of the equivalence principle as well as quantitative relations among the outcomes of its experimental tests. One of the most striking new results obtained through use of this framework is a connection between the breakdown of local Lorentz invariance and the breakdown of the principle that all bodies fall with the same acceleration in a gravitational field. An extensive discussion of experimental tests of the equivalence principle and their significance is also presented. Within the above framework, theory-independent analyses of a broad range of equivalence principle tests are possible. Gravitational redshift experiments. Doppler-shift experiments, the Turner-Hill and Hughes-Drever experiments, and a number of solar-system tests of gravitation theories are analyzed. Application of the techniques of theoretical nuclear physics to the quantitative interpretation of equivalence principle tests using laboratory materials of different composition yields a number of important results. It is found that current Eotvos experiments significantly demonstrate the compatibility of the weak interactions with the equivalence principle. It is also shown that the Hughes-Drever experiment is the most precise test of local Lorentz invariance yet performed. The work leads to a strong, tightly knit empirical basis for the principle of equivalence, the central pillar of the foundations of gravitation theory

H2O incorporation in the phosphorene/a-SiO2 interface: a first-principles study.

Science.gov (United States)

Scopel, Wanderlã L; Souza, Everson S; Miwa, R H

2017-02-22

Based on first-principles calculations, we investigate (i) the energetic stability and electronic properties of single-layer phosphorene (SLP) adsorbed on an amorphous SiO 2 surface (SLP/a-SiO 2 ), and (ii) the further incorporation of water molecules at the phosphorene/a-SiO 2 interface. In (i), we find that the phosphorene sheet binds to a-SiO 2 through van der Waals interactions, even in the presence of oxygen vacancies on the surface. The SLP/a-SiO 2 system presents a type-I band alignment, with the valence (conduction) band maximum (minimum) of the phosphorene lying within the energy gap of the a-SiO 2 substrate. The structure and the surface-potential corrugations promote the formation of electron-rich and electron-poor regions on the phosphorene sheet and at the SLP/a-SiO 2 interface. Such charge density puddles are strengthened by the presence of oxygen vacancies in a-SiO 2 . In (ii), because of the amorphous structure of the surface, we consider a number of plausible geometries for H 2 O embedded in the SLP/a-SiO 2 interface. There is an energetic preference for the formation of hydroxyl (OH) groups on the a-SiO 2 surface. Meanwhile, in the presence of oxygenated water or interstitial oxygen in the phosphorene sheet, we observe the formation of metastable OH bonded to the phosphorene, and the formation of energetically stable P-O-Si chemical bonds at the SLP/a-SiO 2 interface. Further x-ray absorption spectra simulations are performed, which aim to provide additional structural/electronic information on the oxygen atoms forming hydroxyl groups or P-O-Si chemical bonds at the interface region.

2011-02-10

To describe the development and assessment of monographs as an assignment to incorporate evidence-based medicine (EBM) and pharmacoeconomic principles into a third-year pharmacoeconomic course. Eight newly FDA-approved drugs were assigned to 16 teams of students, where each drug was assigned to 2 teams. Teams had to research their drug, write a professional monograph, deliver an oral presentation, and answer questions posed by faculty judges. One team was asked to present evidence for inclusion of the drug into a formulary, while another team presented evidence against inclusion. The teams' average score on the written report was 99.1%; on the oral presentation, 92.5%, and on the online quiz given at the end of the presentations, 77%. Monographs are a successful method of incorporating and integrating learning across different concepts, as well as increasing relevance of pharmacoeconomics in the PharmD curriculum.

The essence of this model of practice is multifaceted, combining principles from anatomy, physiology and neuroscience with psychotherapy to benefit patient care. It has been advocated that possessing multidisciplinary knowledge from these areas of science enhances psychotherapists' holistic care of their depressive patients. A narrative review of the literatures and a qualitative, conceptual synthesis has been performed to create a new theoretical-pragmatic construct. This article introduces the concept of massage practice as a part of psychotherapy practice and presents the potential integration of psychotherapeutic knowledge with clinical decision-making and the management of depressive symptoms. The authors emphasize the usefulness of multi- and interdisciplinary knowledge in the psychotherapeutic process and explain how this knowledge might be extrapolated and incorporated into theoretical and practical settings to benefit depressive patients. The justification for this concept is also presented. The principles set out in this article may be a useful source of information for psychotherapists concerned about their patients' holistic well-being in addition to the psychopathology for which they have sought treatment. Researchers and psychotherapists can obtain valuable and additional knowledge through cross-fertilization of ideas across the arguments presented here.

Full Text Available The paper aims to conduct a study regarding the manner in which corporate governance principles are applied in Romania, in both public and private sector. In the first part of the paper, the corporate governance principles are presented as they are defined in Romania, in comparison with the main international sources of interest in the domain (OECD corporate governance principles, UE legal framework. The corporate governance (CG principles refer to issues regarding board composition, transparency of scope, objectives and policies; they define the relations between directors and managers, shareholders and stakeholders. The research methodology is based on both fundamental research and empirical study on the implementation of corporate governance principles in companies from Romania. The main instrument of research is a corporate governance index, calculated based on a framework proposed by the author. The corporate governance principles are transposed in criteria that compose the framework for the CG index. The results of the study consist of scores for each CG principles and calculation of CG index for seven companies selected from the public and private sector in Romania. The results are analyzed and discussed in order to formulate general and particular recommendations. The main conclusion of this study is that that a legal framework in the area of corporate governance regulation is needed in Romania. I consider that the main CG principles should be enforced by developing a mandatory legal framework.

2015-09-01

Full Text Available This article discusses the principles of quality management and benefits of their implementation in central banks. It is based on new principles of quality management, in particular to: customer focus, leadership, engagement of people, process approach, improvement, evidence-based decision making, and, relationship management. With a view to continuously improving their performance and achieving sustained success, central banks have a realistic opportunity to use these principles in an efficient and effective manner whereby the top management certainly holds the most responsibility. Quality management principles are analysed herein both in their original form and in terms of their implementation in the financial system and its most prominent entity - central bank. The article also incorporates new standard-related terms such as `context` and `risk-based thinking` that significantly strengthen quality management principles and contribute to a more effective and efficient achievement of sustainable success.

Principles of Workplace Democracy: Cases from The Czech Republic

Vopalecký Andy

2017-06-01

Full Text Available The article is about the concept of management of democratic companies in the Czech Republic with a focus on the principles of workplace democracy. The analysis is based on four case studies of democratic companies. The case studies have been drawn up on the basis of a questionnaire survey among the workers of companies and interviews with their executives. The research has shown the importance of even a high rate of implementation of the various principles in all surveyed companies. The best rated principle is “dialogue and listening”. In the case of the principle of “reflection and assessment”, it will show certain deficiencies in the provision of feedback. Principles of workplace democracy identified in interviews mostly agree with the principles referred to in the literature. Resulting from the research, it proposes recommendations and suggestions for further research.

Effect of the Pauli principle in elastic scattering

International Nuclear Information System (INIS)

Picklesimer, A.; Thaler, R.M.

1981-01-01

The effect of imposition of the Pauli principle for two-fragment elastic nuclear scattering is examined. It is shown that the antisymmetrized problem can be cast into the Lippmann-Schwinger form with an effective interaction in which the effect of the Pauli principle is entirely absorbed into the effective interaction potential operator. This result enables the formalism to be developed in analogy with the unsymmetrized formulation. Central to the approach is the choice of the off-shell extension of the transition operator. Comparison is made with a previously proposed treatment based on a different off-shell extension. It is shown that both the antisymmetrized transition operator and the associated optical potential proposed herein are readily expressed as spectator expansions in which the effect of the Pauli principle among the active fermions is incorporated in a physically appealing fashion at each stage of the expansion

Technological incorporation in the Unified Health System (SUS: the problem and ensuing challenges

Directory of Open Access Journals (Sweden)

Reinaldo Guimarães

2014-12-01

Full Text Available Technological incorporation is a central topic among the concerns regarding health care systems. This paper discusses the role of technology dynamics in health systems' cost increases, suggesting two different approaches - a 'pragmatic-economic' approach and a 'rational-defensive' approach - as guidelines to explain the reasons for this centrality. The paper shows how judicialization results from this situation and discusses two doctrinal views - 'reserve for contingencies' and 'rational use' - as the views that usually guide the debates in the courts and among health policy makers. The paper suggests that the attitude currently prevalent in the Brazilian judiciary system can prejudice the principle of equity by improperly evaluating the principle of integrality. We present a brief genealogy of HTA and a timeline of HTA in Brazil. We also discuss the relevance and the impact of Law 12401/2011, which regulates the principle of integrality in the Unified Health System (SUS and propose three challenges to the development of HTA actions aiming at technology incorporation in Brazil. Finally, we discuss the entry and the role of private health insurance companies, emphasizing changes in the scenario and in their position.

The principle of proportionality revisited: interpretations and applications.

Science.gov (United States)

Hermerén, Göran

2012-11-01

The principle of proportionality is used in many different contexts. Some of these uses and contexts are first briefly indicated. This paper focusses on the use of this principle as a moral principle. I argue that under certain conditions the principle of proportionality is helpful as a guide in decision-making. But it needs to be clarified and to be used with some flexibility as a context-dependent principle. Several interpretations of the principle are distinguished, using three conditions as a starting point: importance of objective, relevance of means, and most favourable option. The principle is then tested against an example, which suggests that a fourth condition, focusing on non-excessiveness, needs to be added. I will distinguish between three main interpretations of the principle, some primarily with uses in research ethics, others with uses in other areas of bioethics, for instance in comparisons of therapeutic means and ends. The relations between the principle of proportionality and the precautionary principle are explored in the following section. It is concluded that the principles are different and may even clash. In the next section the principle of proportionality is applied to some medical examples drawn from research ethics and bioethics. In concluding, the status of the principle of proportionality as a moral principle is discussed. What has been achieved so far and what remains to be done is finally summarized.

Volk, Michael L; Lok, Anna S F; Ubel, Peter A; Vijan, Sandeep

2008-01-01

The utilitarian foundation of decision analysis limits its usefulness for many social policy decisions. In this study, the authors examine a method to incorporate competing ethical principles in a decision analysis of liver transplantation for a patient with acute liver failure (ALF). A Markov model was constructed to compare the benefit of transplantation for a patient with ALF versus the harm caused to other patients on the waiting list and to determine the lowest acceptable 5-y posttransplant survival for the ALF patient. The weighting of the ALF patient and other patients was then adjusted using a multiattribute variable incorporating utilitarianism, urgency, and other principles such as fair chances. In the base-case analysis, the strategy of transplanting the ALF patient resulted in a 0.8% increase in the risk of death and a utility loss of 7.8 quality-adjusted days of life for each of the other patients on the waiting list. These harms cumulatively outweighed the benefit of transplantation for an ALF patient having a posttransplant survival of less than 48% at 5 y. However, the threshold for an acceptable posttransplant survival for the ALF patient ranged from 25% to 56% at 5 y, depending on the ethical principles involved. The results of the decision analysis vary depending on the ethical perspective. This study demonstrates how competing ethical principles can be numerically incorporated in a decision analysis.

Turbulence and the Stabilization Principle

Science.gov (United States)

Zak, Michail

2010-01-01

Further results of research, reported in several previous NASA Tech Briefs articles, were obtained on a mathematical formalism for postinstability motions of a dynamical system characterized by exponential divergences of trajectories leading to chaos (including turbulence). To recapitulate: Fictitious control forces are introduced to couple the dynamical equations with a Liouville equation that describes the evolution of the probability density of errors in initial conditions. These forces create a powerful terminal attractor in probability space that corresponds to occurrence of a target trajectory with probability one. The effect in ordinary perceived three-dimensional space is to suppress exponential divergences of neighboring trajectories without affecting the target trajectory. Con sequently, the postinstability motion is represented by a set of functions describing the evolution of such statistical quantities as expectations and higher moments, and this representation is stable. The previously reported findings are analyzed from the perspective of the authors Stabilization Principle, according to which (1) stability is recognized as an attribute of mathematical formalism rather than of underlying physics and (2) a dynamical system that appears unstable when modeled by differentiable functions only can be rendered stable by modifying the dynamical equations to incorporate intrinsic stochasticity.

On the foundation of a variational principle for decaying systems

International Nuclear Information System (INIS)

Szasz, G.I.

1976-01-01

Taking into account the circumstances that the decay of an unstable microscopic system into two fragments is established by the counting of one of the decay products in a detector, the observed exponential decay law then asserts only knowledge of the spatiotemporal behaviour of the probability density (and therewith knowledge of the decaying state) at a large finite distance from the site of decay. We therefore formulate a variational principle, of which stationary functions show this decay behaviour. In addition to the resonant wave functions there are also solutions of the variational principle, which decrease exponentially with increasing distance, i.e., functions which could be used to describe the bound states. As the time-dependent treatment shows, the decaying states cannot occur in isolation in a scattering process. The mathematical characterisation of the decaying states via a variational principle is incorporated in a theory of open physical systems. In contradiction to the variational principle of Schroedinger our principle does not provide complete knowledge of the quantum states, but this is not needed in order to describe the decay. (orig.)

Culture, context and community: ethical considerations for global nursing research.

Harrowing, J N; Mill, J; Spiers, J; Kulig, J; Kipp, W

2010-03-01

High-quality research is essential for the generation of scientific nursing knowledge and the achievement of the Millennium Development Goals. However, the incorporation of Western bioethical principles in the study design may not be suitable, sufficient or relevant to participants in low-income countries and may indeed be harmful and disrespectful. Before engaging in global health studies, nurses must consider carefully the cultural and social context and values of the proposed setting in order to situate the research within the appropriate ethical framework. The purpose of this paper was to examine the ethical principles and considerations that guide health research conducted in international settings using the example of a qualitative study of Ugandan nurses and nurse-midwives by a Canadian researcher. The application of Western bioethical principles with their emphasis on autonomy fails to acknowledge the importance of relevant contextual aspects in the conduct of global research. Because ethics is concerned with how people interact and live together, it is essential that studies conducted across borders be respectful of, and congruent with, the values and needs of the community in which it occurs. The use of a communitarian ethical framework will allow nurse scientists to contribute to the elimination of inequities between those who enjoy prosperity and good health, and those who do not.

On the application of motivation theory to human factors/ergonomics: motivational design principles for human-technology interaction.

Science.gov (United States)

Szalma, James L

2014-12-01

Motivation is a driving force in human-technology interaction. This paper represents an effort to (a) describe a theoretical model of motivation in human technology interaction, (b) provide design principles and guidelines based on this theory, and (c) describe a sequence of steps for the. evaluation of motivational factors in human-technology interaction. Motivation theory has been relatively neglected in human factors/ergonomics (HF/E). In both research and practice, the (implicit) assumption has been that the operator is already motivated or that motivation is an organizational concern and beyond the purview of HF/E. However, technology can induce task-related boredom (e.g., automation) that can be stressful and also increase system vulnerability to performance failures. A theoretical model of motivation in human-technology interaction is proposed, based on extension of the self-determination theory of motivation to HF/E. This model provides the basis for both future research and for development of practical recommendations for design. General principles and guidelines for motivational design are described as well as a sequence of steps for the design process. Human motivation is an important concern for HF/E research and practice. Procedures in the design of both simple and complex technologies can, and should, include the evaluation of motivational characteristics of the task, interface, or system. In addition, researchers should investigate these factors in specific human-technology domains. The theory, principles, and guidelines described here can be incorporated into existing techniques for task analysis and for interface and system design.

Setting up an ethics of ecosystem research structure based on the precautionary principle.

Science.gov (United States)

Farmer, Michael C

2013-01-01

Ethical practices in ecological field research differ from those in laboratory research in more than the technical setting and the important distinction between population-level and individual-based concerns. The number of stakeholders affected by the conduct of field research is far larger; private landholders, public water utilities, public land managers, local industries, and communities large and small are only some of those who may be impacted. As research review boards move to establish specific ethical practices for field biologists, the process of identifying appropriate standards will affect the degree to which research will ultimately be disrupted. Standards that lead to research protocols that alienate key interests are not likely to be sustainable. Already, standards that have conflicted with the primary values of a key interest have resulted in disruptions to research and scientific progress. One way to manage this problem of deeply competing interests is to avoid the deepest offenses to any relevant interest group in the design of a proposed study. This is an application of the precautionary principle and is likely to generate a more sustainable balance among competing interests. Unfortunately, this process is also likely to be a never-ending, consensus-seeking process. Fortunately, scientists can have enormous influence on the process if they choose to engage in it early. If scientists use their expertise to function as honest brokers among affected interests, their own interest in scientific research progress is likely to be better met.

Grunspan, Daniel Z; Nesse, Randolph M; Barnes, M Elizabeth; Brownell, Sara E

2018-01-01

Abstract Background and objectives Evolutionary medicine is a rapidly growing field that uses the principles of evolutionary biology to better understand, prevent and treat disease, and that uses studies of disease to advance basic knowledge in evolutionary biology. Over-arching principles of evolutionary medicine have been described in publications, but our study is the first to systematically elicit core principles from a diverse panel of experts in evolutionary medicine. These principles should be useful to advance recent recommendations made by The Association of American Medical Colleges and the Howard Hughes Medical Institute to make evolutionary thinking a core competency for pre-medical education. Methodology The Delphi method was used to elicit and validate a list of core principles for evolutionary medicine. The study included four surveys administered in sequence to 56 expert panelists. The initial open-ended survey created a list of possible core principles; the three subsequent surveys winnowed the list and assessed the accuracy and importance of each principle. Results Fourteen core principles elicited at least 80% of the panelists to agree or strongly agree that they were important core principles for evolutionary medicine. These principles over-lapped with concepts discussed in other articles discussing key concepts in evolutionary medicine. Conclusions and implications This set of core principles will be helpful for researchers and instructors in evolutionary medicine. We recommend that evolutionary medicine instructors use the list of core principles to construct learning goals. Evolutionary medicine is a young field, so this list of core principles will likely change as the field develops further. PMID:29493660

Incorporating intersectionality theory into population health research methodology: challenges and the potential to advance health equity.

Science.gov (United States)

Bauer, Greta R

2014-06-01

Intersectionality theory, developed to address the non-additivity of effects of sex/gender and race/ethnicity but extendable to other domains, allows for the potential to study health and disease at different intersections of identity, social position, processes of oppression or privilege, and policies or institutional practices. Intersectionality has the potential to enrich population health research through improved validity and greater attention to both heterogeneity of effects and causal processes producing health inequalities. Moreover, intersectional population health research may serve to both test and generate new theories. Nevertheless, its implementation within health research to date has been primarily through qualitative research. In this paper, challenges to incorporation of intersectionality into population health research are identified or expanded upon. These include: 1) confusion of quantitative terms used metaphorically in theoretical work with similar-sounding statistical methods; 2) the question of whether all intersectional positions are of equal value, or even of sufficient value for study; 3) distinguishing between intersecting identities, social positions, processes, and policies or other structural factors; 4) reflecting embodiment in how processes of oppression and privilege are measured and analysed; 5) understanding and utilizing appropriate scale for interactions in regression models; 6) structuring interaction or risk modification to best convey effects, and; 7) avoiding assumptions of equidistance or single level in the design of analyses. Addressing these challenges throughout the processes of conceptualizing and planning research and in conducting analyses has the potential to improve researchers' ability to more specifically document inequalities at varying intersectional positions, and to study the potential individual- and group-level causes that may drive these observed inequalities.

In the United States the recent termination of funding for research on therapy for incorporated radionuclides has virtually halted progress on improved or new agents and procedures for removing radioactivity from the body. Research was eliminated, but is still needed on new removal agents, improved delivery system, in vitro test systems, and the toxicology of treatments. For many radionuclides, no adequate therapy exists. The relationship between radionuclide removal and reduction in cancer risk is still unanswered. Without proper research support, needed improvements in the treatment for incorporated radionuclides in the US are uncertain

Infusing Adult Education Principles Into a Health Insurance Literacy Program.

Science.gov (United States)

Brown, Virginia

2018-03-01

Health insurance literacy is an emerging concept in the health education and health promotion field. The passage of the Affordable Care Act highlighted the link between health insurance and health outcomes. However, the law does not specifically address how the public should be educated on choosing an appropriate health insurance plan. Research shows adults, regardless of previous health insurance status, are likely confused and uncertain about their selection. The University of Maryland Extension developed and created health insurance Smart Choice Health Insurance™ to reduce confusion and increase confidence and capability to make this decision. Andragogy, an adult learning theory, was used to guide the development of the program and help ensure best practices are used to achieve desired outcomes. Using the six principles of andragogy, the team incorporated reality-based case studies, allowed adults time to practice, and emphasized choice making and many other elements to create an atmosphere conducive to adult learning. Results from Smart Choice indicate the program is successful in reducing confusion and increasing confidence. Furthermore, feedback from participants and trained educators indicates that adults were engaged in the program and found the materials useful. Based on program success, creation of new health insurance literacy programs grounded in adult education principles is under way.

Working with LGBT Individuals: Incorporating Positive Psychology into Training and Practice

Lytle, Megan C.; Vaughan, Michelle D.; Rodriguez, Eric M.; Shmerler, David L.

2014-01-01

This paper examines how positive psychology principles can be incorporated into clinical training and practice to work with lesbian, gay, bisexual and transgender (LGBT) clients. LGBT psychology literature has all too often relied on heterosexual and cisgender reference groups as the norm with respect to psychological health, primarily framing the experiences of LGBT individuals through the lens of psychopathology. As a result, strengths that could be ascribed to the LGBT experience have been overlooked within training and practice. While positive psychology is actively being incorporated into clinical and counseling psychology curricula, broadening the paradigm to include LGBT individuals has generally not been included in the discussion. Specific recommendations for training psychologists to incorporate and foster positive social institutions, positive subjective experiences and character strengths when working with LGBT clients and celebrating their unique experiences are provided.

Liu, W. K.; Belytschko, T.; Besterfield, G. H.

1987-01-01

A Probabilistic Hu-Washizu Variational Principle (PHWVP) for the Probabilistic Finite Element Method (PFEM) is presented. This formulation is developed for both linear and nonlinear elasticity. The PHWVP allows incorporation of the probabilistic distributions for the constitutive law, compatibility condition, equilibrium, domain and boundary conditions into the PFEM. Thus, a complete probabilistic analysis can be performed where all aspects of the problem are treated as random variables and/or fields. The Hu-Washizu variational formulation is available in many conventional finite element codes thereby enabling the straightforward inclusion of the probabilistic features into present codes.

Understanding policy research in liminal spaces: Think tank responses to diverging principles of legitimacy.

Science.gov (United States)

McLevey, John

2015-04-01

Research on scientific, social scientific, and technical knowledge is increasingly focused on changes in institutionalized fields, such as the commercialization of university-based knowledge. Much less is known about how organizations produce and promote knowledge in the 'thick boundaries' between fields. In this article, I draw on 53 semi-structured interviews with Canadian think-tank executives, researchers, research fellows, and communication officers to understand how think-tank knowledge work is linked to the liminal spaces between institutionalized fields. First, although think-tank knowledge work has a broadly utilitarian epistemic culture, there are important differences between organizations that see intellectual simplicity and political consistency as the most important marker of credibility, versus those that emphasize inconsistency. A second major difference is between think tanks that argue for the separation of research and communication strategies and those that conflate them from beginning to end, arguably subordinating research to demands from more powerful fields. Finally, think tanks display different degrees of instrumentalism toward the public sphere, with some seeking publicity as an end in itself and others using it as a means to influence elite or public opinion. Together, we can see these differences as responses to diverging principles of legitimacy.

Organizing principles as tools for bridging the gap between system theory and biological experimentation.

Science.gov (United States)

Mekios, Constantinos

2016-04-01

Twentieth-century theoretical efforts towards the articulation of general system properties came short of having the significant impact on biological practice that their proponents envisioned. Although the latter did arrive at preliminary mathematical formulations of such properties, they had little success in showing how these could be productively incorporated into the research agenda of biologists. Consequently, the gap that kept system-theoretic principles cut-off from biological experimentation persisted. More recently, however, simple theoretical tools have proved readily applicable within the context of systems biology. In particular, examples reviewed in this paper suggest that rigorous mathematical expressions of design principles, imported primarily from engineering, could produce experimentally confirmable predictions of the regulatory properties of small biological networks. But this is not enough for contemporary systems biologists who adopt the holistic aspirations of early systemologists, seeking high-level organizing principles that could provide insights into problems of biological complexity at the whole-system level. While the presented evidence is not conclusive about whether this strategy could lead to the realization of the lofty goal of a comprehensive explanatory integration, it suggests that the ongoing quest for organizing principles is pragmatically advantageous for systems biologists. The formalisms postulated in the course of this process can serve as bridges between system-theoretic concepts and the results of molecular experimentation: they constitute theoretical tools for generalizing molecular data, thus producing increasingly accurate explanations of system-wide phenomena.

Background: In the last decades, children's understanding of mathematical principles has become an important research topic. Different from the commutativity and inversion principles, only few studies have focused on children's understanding of the addition/subtraction complement principle (if a - b = c, then c + b = a), mainly relying on verbal…

Progress in classical and quantum variational principles

International Nuclear Information System (INIS)

Gray, C G; Karl, G; Novikov, V A

2004-01-01

We review the development and practical uses of a generalized Maupertuis least action principle in classical mechanics in which the action is varied under the constraint of fixed mean energy for the trial trajectory. The original Maupertuis (Euler-Lagrange) principle constrains the energy at every point along the trajectory. The generalized Maupertuis principle is equivalent to Hamilton's principle. Reciprocal principles are also derived for both the generalized Maupertuis and the Hamilton principles. The reciprocal Maupertuis principle is the classical limit of Schroedinger's variational principle of wave mechanics and is also very useful to solve practical problems in both classical and semiclassical mechanics, in complete analogy with the quantum Rayleigh-Ritz method. Classical, semiclassical and quantum variational calculations are carried out for a number of systems, and the results are compared. Pedagogical as well as research problems are used as examples, which include nonconservative as well as relativistic systems. '... the most beautiful and important discovery of Mechanics.'

Enhancing the hermeneutic single-case efficacy design: Bridging the research-practice gap.

Science.gov (United States)

Wall, Jessie M; Kwee, Janelle L; Hu, Monica; McDonald, Marvin J

2017-09-01

Systematic case study designs are emerging as alternative paradigm strategies for psychotherapy and social science research. Through enhanced sensitivity to context, these designs examine idiographic profiles of causal processes. We specifically advocate the use of the hermeneutic single-case efficacy design (HSCED). HSCED has recently been used to investigate the efficacy of an existing therapy with a new population (Observed and Experiential Integration for athlete performance barriers) and an emerging therapy (Lifespan Integration Therapy). We describe innovations in HSCED that were implemented for these studies. These developments include (a) integrating psychotherapists as case developers, (b) incorporating multiple cases in one investigation, and (c) tailoring the repertoire of assessment tools. These extensions strategically incorporated principles of contextual paradigms in HSCED, thus complementing single-case designs that neglect idiographic contexts. We discuss recommendations for using HSCED in practice-based research, highlighting its potential as a bridge to address the research-practice gap.

The Principle-Based Method of Practical Ethics.

Science.gov (United States)

Spielthenner, Georg

2017-09-01

This paper is about the methodology of doing practical ethics. There is a variety of methods employed in ethics. One of them is the principle-based approach, which has an established place in ethical reasoning. In everyday life, we often judge the rightness and wrongness of actions by their conformity to principles, and the appeal to principles plays a significant role in practical ethics, too. In this paper, I try to provide a better understanding of the nature of principle-based reasoning. To accomplish this, I show in the first section that these principles can be applied to cases in a meaningful and sufficiently precise way. The second section discusses the question how relevant applying principles is to the resolution of ethical issues. This depends on their nature. I argue that the principles under consideration in this paper should be interpreted as presumptive principles and I conclude that although they cannot be expected to bear the weight of definitely resolving ethical problems, these principles can nevertheless play a considerable role in ethical research.

Carrieri, D; Bewshea, C; Walker, G; Ahmad, T; Bowen, W; Hall, A; Kelly, S

2016-09-27

Current guidelines on consenting individuals to participate in genomic research are diverse. This creates problems for participants and also for researchers, particularly for clinicians who provide both clinical care and research to their patients. A group of 14 stakeholders met on 7 October 2015 in Exeter to discuss the ethical issues and the best practice arising in clinically based genomic research, with particular emphasis on the issue of returning results to study participants/patients in light of research findings affecting research and clinical practices. The group was deliberately multidisciplinary to ensure that a diversity of views was represented. This report outlines the main ethical issues, areas of best practice and principles underlying ethical clinically based genomic research discussed during the meeting. The main point emerging from the discussion is that ethical principles, rather than being formulaic, should guide researchers/clinicians to identify who the main stakeholders are to consult with for a specific project and to incorporate their voices/views strategically throughout the lifecycle of each project. We believe that the mix of principles and practical guidelines outlined in this report can contribute to current debates on how to conduct ethical clinically based genomic research.

Plant protection products (PPPs) and the active substance(s) contained within them are rigorously and comprehensively tested prior to registration to ensure that human health is not impacted by their use. In recent years, there has been a widespread drive to have more relevant testing strategies (e.g., ILSI/HESI-ACSA and new EU Directives), which also take account of animal welfare, including the 3R (replacement, refinement, and reduction) principles. The toxicity potential of one such new active substance, sulfoxaflor, a sulfoximine insecticide (CAS #946578-00-3), was evaluated utilizing innovative testing strategies comprising: (1) an integrated testing scheme to optimize information obtained from as few animals as possible (i.e., 3R principles) through modifications of standard protocols, such as enhanced palatability study design, to include molecular endpoints, additional neurotoxicity and immunotoxicity parameters in a subchronic toxicity study, and combining multiple test guidelines into one study protocol; (2) generation of toxicokinetic data across dose levels, sexes, study durations, species, strains and life stages, without using satellite animals, which was a first for PPP development, and (3) addition of prospective mode of action (MoA) endpoints within repeat dose toxicity studies as well as proactive inclusion of specific MoA studies as an integral part of the development program. These novel approaches to generate key data early in the safety evaluation program facilitated informed decision-making on the need for additional studies and contributed to a more relevant human health risk assessment. This supplement also contains papers which describe in more detail the approach taken to establish the MoA and human relevance framework related to toxicities elicited by sulfoxaflor in the mammalian toxicology studies: developmental toxicity in rats mediated via the fetal muscle nicotinic acetylcholine receptor (nAChR) ( Ellis-Hutchings et al. 2014 ); liver

Principles and applications of measurement and uncertainty analysis in research and calibration

Energy Technology Data Exchange (ETDEWEB)

Wells, C.V.

1992-11-01

Interest in Measurement Uncertainty Analysis has grown in the past several years as it has spread to new fields of application, and research and development of uncertainty methodologies have continued. This paper discusses the subject from the perspectives of both research and calibration environments. It presents a history of the development and an overview of the principles of uncertainty analysis embodied in the United States National Standard, ANSI/ASME PTC 19.1-1985, Measurement Uncertainty. Examples are presented in which uncertainty analysis was utilized or is needed to gain further knowledge of a particular measurement process and to characterize final results. Measurement uncertainty analysis provides a quantitative estimate of the interval about a measured value or an experiment result within which the true value of that quantity is expected to lie. Years ago, Harry Ku of the United States National Bureau of Standards stated that ``The informational content of the statement of uncertainty determines, to a large extent, the worth of the calibrated value.`` Today, that statement is just as true about calibration or research results as it was in 1968. Why is that true? What kind of information should we include in a statement of uncertainty accompanying a calibrated value? How and where do we get the information to include in an uncertainty statement? How should we interpret and use measurement uncertainty information? This discussion will provide answers to these and other questions about uncertainty in research and in calibration. The methodology to be described has been developed by national and international groups over the past nearly thirty years, and individuals were publishing information even earlier. Yet the work is largely unknown in many science and engineering arenas. I will illustrate various aspects of uncertainty analysis with some examples drawn from the radiometry measurement and calibration discipline from research activities.

Advancing Pre-Health Humanities as Intensive Research Practice: Principles and Recommendations from a Cross-Divisional Baccalaureate Setting.

Science.gov (United States)

Singer, Sarah Ann; Weed, Kym; Edwell, Jennifer; Jack, Jordynn; Thrailkill, Jane F

2017-12-01

This essay argues that pre-health humanities programs should focus on intensive research practice for baccalaureate students and provides three guiding principles for implementing it. Although the interdisciplinary nature of health humanities permits baccalaureate students to use research methods from the natural sciences, social sciences, and humanities, pre-health humanities coursework tends to force students to adopt only one of many disciplinary identities. Alternatively, an intensive research approach invites students to critically select and combine methods from multiple (and seemingly opposing) disciplines to ask and answer questions about health problems more innovatively. Using the authors' experiences with implementing health humanities baccalaureate research initiatives at The University of North Carolina at Chapel Hill, the authors contend that pre-health humanities programs should teach and study multiple disciplinary research methods and their values; examine how health humanities research might transfer across disciplines; and focus on mentoring opportunities for funding, presenting, and publishing research. These recommendations have the potential to create unprecedented research experiences for baccalaureate students as they prepare to enter careers within and beyond the allied health professions.

Drawing on the Greater Involvement of People with HIV/AIDS (GIPA) principle, the HIV/AIDS movement began to "democratize" research in Canada in the mid-1990s. To date, there is little evidence about the success of the community-based research (CBR) movement in relation to the implementation of GIPA. We draw on findings from a larger study examining barriers and facilitating factors in relation to HIV-related CBR in Ontario, Canada. An online survey was completed by 39 senior managers in Ontario AIDS service organizations (ASOs). Twenty-five in-depth, semi-structured interviews were then conducted to further explore the survey findings. Survey respondents reported that, compared to researchers and frontline service providers, people living with HIV/AIDS (PLWHA) tended to be the least involved in all stages (input, process and outcome) of CBR projects. AIDS service organizations with a mandate that included serving rural and urban communities reported even lower levels of PLWHA involvement in CBR. Qualitative data reveal complex barriers that make meaningful PLWHA engagement in CBR difficult, including: HIV-related stigma; health-related challenges; "credentialism"; lack of capacity to engage in research; other issues taking priority; and mistrust of researchers. Facilitating factors included valuing lived experience; training and mentoring opportunities; financial compensation; trust building; and accommodating PLWHA's needs. While there is strong support for the GIPA principles in theory, practice lags far behind.

Diagnostic classification systems do not incorporate phenomenological research findings about the three core symptom domains of delirium (Attentional/Cognitive, Circadian, Higher Level Thinking). We evaluated classification performances of novel Trzepacz, Meagher, and Franco research diagnostic criteria (TMF) that incorporate those domains and ICD-10, DSM-III-R, DSM-IV, and DSM-5. Primary data analysis of 641 patients with mixed neuropsychiatric profiles. Delirium (n=429) and nondelirium (n=212) reference standard groups were identified using cluster analysis of symptoms assessed using the Delirium Rating Scale-Revised-98. Accuracy, sensitivity, specificity, positive and negative predictive values (PPV, NPV), and likelihood ratios (LR+, LR-) are reported. TMF criteria had high sensitivity and specificity (87.4% and 89.2%), more balanced than DSM-III-R (100% and 31.6%), DSM-IV (97.7% and 74.1%), DSM-5 (97.7% and 72.6%), and ICD-10 (66.2% and 100%). PPV of DSM-III-R, DSM-IV, and DSM-5 were 90%. ICD-10 had the lowest NPV (59.4%). TMF had the highest LR+ (8.06) and DSM-III-R the lowest LR- (0.0). Overall, values for DSM-IV and DSM-5 were similar, whereas for ICD-10 and DSM-III-R were inverse of each other. In the pre-existing cognitive impairment/dementia subsample (n=128), TMF retained its highest LR+ though specificity (58.3%) became less well balanced with sensitivity (87.9%), which still exceeded that of DSM. TMF research diagnostic criteria performed well, with more balanced sensitivity and specificity and the highest likelihood ratio for delirium identification. Reflecting the three core domains of delirium, TMF criteria may have advantages in biological research where delineation of this syndrome is important. Copyright © 2016. Published by Elsevier Inc.

[Research on fast classification based on LIBS technology and principle component analyses].

Yu, Qi; Ma, Xiao-Hong; Wang, Rui; Zhao, Hua-Feng

2014-11-01

Laser-induced breakdown spectroscopy (LIBS) and the principle component analysis (PCA) were combined to study aluminum alloy classification in the present article. Classification experiments were done on thirteen different kinds of standard samples of aluminum alloy which belong to 4 different types, and the results suggested that the LIBS-PCA method can be used to aluminum alloy fast classification. PCA was used to analyze the spectrum data from LIBS experiments, three principle components were figured out that contribute the most, the principle component scores of the spectrums were calculated, and the scores of the spectrums data in three-dimensional coordinates were plotted. It was found that the spectrum sample points show clear convergence phenomenon according to the type of aluminum alloy they belong to. This result ensured the three principle components and the preliminary aluminum alloy type zoning. In order to verify its accuracy, 20 different aluminum alloy samples were used to do the same experiments to verify the aluminum alloy type zoning. The experimental result showed that the spectrum sample points all located in their corresponding area of the aluminum alloy type, and this proved the correctness of the earlier aluminum alloy standard sample type zoning method. Based on this, the identification of unknown type of aluminum alloy can be done. All the experimental results showed that the accuracy of principle component analyses method based on laser-induced breakdown spectroscopy is more than 97.14%, and it can classify the different type effectively. Compared to commonly used chemical methods, laser-induced breakdown spectroscopy can do the detection of the sample in situ and fast with little sample preparation, therefore, using the method of the combination of LIBS and PCA in the areas such as quality testing and on-line industrial controlling can save a lot of time and cost, and improve the efficiency of detection greatly.

Integrating Bioethics into Clinical and Translational Science Research: A Roadmap

Science.gov (United States)

Shapiro, Robyn S.; Layde, Peter M.

2008-01-01

Abstract Recent initiatives to improve human health emphasize the need to effectively and appropriately translate new knowledge gleaned from basic biomedical and behavioral research to clinical and community application. To maximize the beneficial impact of scientific advances in clinical practice and community health, and to guard against potential deleterious medical and societal consequences of such advances, incorporation of bioethics at each stage of clinical and translational science research is essential. At the earliest stage, bioethics input is critical to address issues such as whether to limit certain areas of scientific inquiry. Subsequently, bioethics input is important to assure not only that human subjects trials are conducted and reported responsibly, but also that results are incorporated into clinical and community practices in a way that promotes and protects bioethical principles. At the final stage of clinical and translational science research, bioethics helps to identify the need and approach for refining clinical practices when safety or other concerns arise. The framework we present depicts how bioethics interfaces with each stage of clinical and translational science research, and suggests an important research agenda for systematically and comprehensively assuring bioethics input into clinical and translational science initiatives.

Measures of socio-economic impacts of conservation interventions have largely been restricted to externally defined indicators focused on income, which do not reflect people's priorities. Using a holistic, locally grounded conceptualization of human well-being instead provides a way to understand the multi-faceted impacts of conservation on aspects of people's lives that they value. Conservationists are engaging with well-being for both pragmatic and ethical reasons, yet current guidance on how to operationalize the concept is limited. We present nine guiding principles based around a well-being framework incorporating material, relational and subjective components, and focused on gaining knowledge needed for decision-making. The principles relate to four key components of an impact evaluation: (i) defining well-being indicators, giving primacy to the perceptions of those most impacted by interventions through qualitative research, and considering subjective well-being, which can affect engagement with conservation; (ii) attributing impacts to interventions through quasi-experimental designs, or alternative methods such as theory-based, case study and participatory approaches, depending on the setting and evidence required; (iii) understanding the processes of change including evidence of causal linkages, and consideration of trajectories of change and institutional processes; and (iv) data collection with methods selected and applied with sensitivity to research context, consideration of heterogeneity of impacts along relevant societal divisions, and conducted by evaluators with local expertise and independence from the intervention. © 2015 The Authors.

Abstract: As the health care delivery landscape changes, medical schools must develop creative strategies for preparing future physicians to provide quality care in this new environment. Despite the growing prominence of the patient-centered medical home (PCMH as an effective model for health care delivery, few medical schools have integrated formal education on the PCMH into their curricula. Incorporating the PCMH model into medical school curricula is important to ensure that students have a comprehensive understanding of the different models of health care delivery and can operate effectively as physicians. The authors provide a detailed description of the process by which the Weill Cornell Community Clinic (WCCC, a student-run free clinic, has integrated PCMH principles into a service-learning initiative. The authors assessed patient demographics, diagnoses, and satisfaction along with student satisfaction. During the year after a PCMH model was adopted, 112 students and 19 licensed physicians volunteered their time. A review of the 174 patients seen from July 2011 to June 2012 found that the most common medical reasons for visits included management of hypertension, hyperlipidemia, diabetes, gastrointestinal conditions, arthritis, anxiety, and depression.

Laura A. Warner

2015-02-01

Full Text Available A substantial amount of water is applied to Florida landscapes, and encouraging water conservation through irrigation practices has been identified as a priority programming area where there is great opportunity to positively affect the state’s water resources. Florida Extension addresses this priority area through educational programming. Social marketing has been identified as a promising approach to changing behaviors that influence environmental issues, such as water-saving irrigation technologies and practices. This approach recognizes that there are barriers that prevent individuals from engaging in positive behavior changes. This study evaluated an irrigation seminar using a retrospective pretest-posttest design that incorporated elements of a social marketing intercept survey. Thirty-four attendees participated and primarily represented green industry professional and government sectors. Study objectives were to evaluate the workshop and describe the audience using social marketing principles for future program planning based on audience research. The audience rated their descriptive norms, a strong predictor of behavioral change, lower than their injunctive norms, a less robust predictor. The majority planned to adopt at least one water-conservation best management practice as a result of the workshop. We make recommendations for applying social marketing principles to Extension programming.

The Specificity Principle in Acculturation Science

2016-01-01

The Specificity Principle in Acculturation Science asserts that specific setting conditions of specific people at specific times moderate specific domains in acculturation by specific processes. Our understanding of acculturation depends critically on what is studied where, in whom, how, and when. This article defines, explains, and illustrates the Specificity Principle in Acculturation Science. Research hypotheses about acculturation can be more adequately tested, inconsistencies and discrepancies in the acculturation literature can be satisfactorily resolved, acculturation interventions can be tailored to be more successful, and acculturation policies can be brought to new levels of effectiveness if the specificity principle that governs acculturation science is more widely recognized.

Unifying generative and discriminative learning principles

Strickert Marc

2010-02-01

Full Text Available Abstract Background The recognition of functional binding sites in genomic DNA remains one of the fundamental challenges of genome research. During the last decades, a plethora of different and well-adapted models has been developed, but only little attention has been payed to the development of different and similarly well-adapted learning principles. Only recently it was noticed that discriminative learning principles can be superior over generative ones in diverse bioinformatics applications, too. Results Here, we propose a generalization of generative and discriminative learning principles containing the maximum likelihood, maximum a posteriori, maximum conditional likelihood, maximum supervised posterior, generative-discriminative trade-off, and penalized generative-discriminative trade-off learning principles as special cases, and we illustrate its efficacy for the recognition of vertebrate transcription factor binding sites. Conclusions We find that the proposed learning principle helps to improve the recognition of transcription factor binding sites, enabling better computational approaches for extracting as much information as possible from valuable wet-lab data. We make all implementations available in the open-source library Jstacs so that this learning principle can be easily applied to other classification problems in the field of genome and epigenome analysis.

Pay for performance programs in Australia: a need for guiding principles.

Scott, Ian A

2008-11-01

Pay-for-performance (P4P) programs which reward clinical providers with incentive payments based on one or more measures of quality of care are now common in the United States and the United Kingdom and it is likely they will attract increasing interest in Australia. However, empirical evidence demonstrating effectiveness of such programs is limited and many existing programs have not had rigorous outcome evaluation. To maximise success, future P4P programs should incorporate the lessons and insights obtained from previous experience. Based on a review of published trials, program evaluations and position statements, the following principles that may guide future program design and implementation were synthesised: 1) formulate a rationale and a business case for P4P; 2) use established evidence-based performance measures; 3) use rigorous and verifiable methods of data collection and analysis; 4) define performance targets using absolute and relative thresholds; 5) use rewards that are sufficient, equitable and transparent; 6) address appropriateness of provider responses and avoid perverse incentives; 7) implement communication and feedback strategies; 8) use existing organisational structures to implement P4P programs; 9) attribute credit for performance to participants in ways that foster population-based perspectives; and 10) invest in outcomes and health service research. Recommendations flowing from these principles relevant to Australian settings are provided.

SOCIAL MARKETING : A NEW APPROACH IN MENTAL HEALTH RESEARCH

Tiwari, S.C.

Social marketing has a proven role in marketing and many manufacturing establishments/ organizations have been marketing their products incorporating social marketing research. Social marketing has its root in the ground fact that the perceptions and expectations of the consumers are important in influencing buying behaviour. The principles of social marketing, therefore, have been extensively utilized in the areas of consumer products. These are also used in several other fields for modifying behaviours such as civil administration, public establishments etc. In health sector social marketing has not found appropriate application whereas it could be utilized in an effective way for creating awareness, formulating health related policies, their implementation and for preventing a variety of illnesses/abnormal behaviours etc. With this background knowledge about social marketing, the author hypothesized that abnormal behaviours could be modified, health education packages could be developed to make more acceptable and effective and desired behaviours could be induced if perceptions and expectations of the community (consumers) are known a prioriori and their expectations are incorporated in programmes and policies. Thus, the author utilizing the concepts of social marketing for understanding community′s perceptions and expectations regarding issues of health, and for incorporating the same in health related programmes and policies, introduced this research concept in medical field in this country. The important findings of three research projects based on the concepts of social marketing research and their implications have been discussed. PMID:21494494

The practice of community based participatory research (CBPR) has evolved over the past 20 years with the recognition that health equity is best achieved when academic researchers form collaborative partnerships with communities. This article theorizes the possibility that core principles of CBPR cannot be realistically applied unless unequal power relations are identified and addressed. It provides theoretical and empirical perspectives for understanding power, privilege, researcher identity and academic research team composition, and their effects on partnering processes and health disparity outcomes. The team's processes of conducting seven case studies of diverse partnerships in a national cross-site CBPR study are analyzed; the multi-disciplinary research team's self-reflections on identity and positionality are analyzed, privileging its combined racial, ethnic, and gendered life experiences, and integrating feminist and post-colonial theory into these reflections. Findings from the inquiry are shared, and incorporating academic researcher team identity is recommended as a core component of equalizing power distribution within CBPR.

Human rights, politics, and reviews of research ethics.

Science.gov (United States)

Beyrer, Chris; Kass, Nancy E

2002-07-20

Although the human rights movement and the sphere of research ethics have overlapping principles and goals, there has been little attempt to incorporate external political and human rights contexts into research ethics codes or ethics reviews. Every element of a research ethics review--the balance of risks and benefits, the assurance of rights for individual participants, and the fair selection of research populations--can be affected by the political and human rights background in which a study is done. Research that at first seems to be low in risk may become high in risk if implemented in a country where the government might breach the confidentiality of study results or where results might be used to deport a refugee group. Researchers should determine whether research could or should be done by consulting human rights organisations and, when possible, a trusted colleague, to learn the background political context and human rights conditions of the settings in which they propose to do research.

The principle of optimisation: reasons for success and legal criticism

International Nuclear Information System (INIS)

Fernandez Regalado, Luis

2008-01-01

The International Commission on Radiological Protection (ICRP) has adopted new recommendations in 2007. In broad outlines they fundamentally continue the recommendations already approved in 1990 and later on. The principle of optimisation of protection, together with the principles of justification and dose limits, remains playing a key role of the ICRP recommendations, and it has so been for the last few years. This principle, somehow reinforced in the 2007 ICRP recommendations, has been incorporated into norms and legislation which have peacefully been in force in many countries all over the world. There are three main reasons to explain the success in the application of the principle of optimisation in radiological protection: First, the subjectivity of the sentence that embraces the principle of optimisation, 'As low as reasonably achievable' (ALARA), that allows different valid interpretations under different circumstances. Second, the pragmatism and adaptability of ALARA to all exposure situations. And third, the scientific humbleness which is behind the principle of optimisation, which makes a clear contrast with the old fashioned scientific positivism that enshrined scientist opinions. Nevertheless, from a legal point of view, there is some criticism cast over the principle of optimisation in radiological protection, where it has been transformed in compulsory norm. This criticism is based on two arguments: The lack of democratic participation in the process of elaboration of the norm, and the legal uncertainty associated to its application. Both arguments are somehow known by the ICRP which, on the one hand, has broadened the participation of experts, associations and the professional radiological protection community, increasing the transparency on how decisions on recommendations have been taken, and on the other hand, the ICRP has warned about the need for authorities to specify general criteria to develop the principle of optimisation in national

Incorporation of tritium from wrist watches

International Nuclear Information System (INIS)

Schoenhofer, F.; Pock, K.

1995-01-01

Watches are consumer products and are subject to the regulations that control food and consumer products. Elevated concentrations of tritium were found in the urine of persons who wore wrist watches with luminous dials and plastic cases. High emission of tritium from these watches were observed. In an experiment, a volunteer wore a watch with high emissions and the build-up of the tritium concentration in urine was monitored, as well as the decline after removing the watch. Possible pathways for the incorporation and its mechanism are considered. In spite of the relatively high activity concentrations observed, the dose is negligible. On the other hand, the principle 'ALARA' can be achieved without any costs by simply choosing other types of watches. (author). 12 refs., 2 figs., 2 tabs

Facilitating Transfer of Skills and Strategies in Occupational Therapy Practice: Practical Application of Transfer Principles.

Science.gov (United States)

Babulal, Ganesh M; Foster, Erin R; Wolf, Timothy J

2016-01-01

In Occupational Therapy (OT) practice, practitioners assume that the skills and strategies taught to clients during rehabilitation will transfer to performance and participation in everyday life. Despite transfer serving as a practice foundation, outcome studies conclude that this assumption of transfer is not occurring and it often results in decreased efficacy of rehabilitation. This paper investigated key aspects of transfer and found concepts in the psychology literature that can support transfer of skills and strategies in OT. Six key principles proposed from educational psychology can serve as a guide for practitioners to better train for transfer. In this paper, we discuss the six principles and apply concepts from psychology. Each principle is supported with examples of how they may be incorporated OT practice. If occupational therapists understand these principles and implement them in treatment, the efficacy of treatment may improve for many populations.

'Relief of oppression': an organizing principle for researchers' obligations to participants in observational studies in the developing world.

Lavery, James V; Bandewar, Sunita V S; Kimani, Joshua; Upshur, Ross E G; Plummer, Frances A; Singer, Peter A

A central question in the debate about exploitation in international research is whether investigators and sponsors from high-income countries (HIC) have obligations to address background conditions of injustice in the communities in which they conduct their research, beyond the healthcare and other research-related needs of participants, to aspects of their basic life circumstances. In this paper, we describe the Majengo sexually transmitted disease (STD) Cohort study, a long-term prospective, observational cohort of sex workers in Nairobi, Kenya. Despite important scientific contributions and a wide range of benefits to the women of the cohort, most of the women have remained in the sex trade during their long-standing participation in the cohort, prompting allegations of exploitation. The Majengo STD cohort case extends the debate about justice in international research ethics beyond clinical trials into long-term observational research. We sketch the basic features of a new approach to understanding and operationalizing obligations of observational researchers, which we call 'relief of oppression'. 'Relief of oppression' is an organizing principle, analogous to the principle of harm reduction that is now widely applied in public health practice. Relief of oppression aims to help observational researchers working in conditions of injustice and deprivation to clarify their ethical obligations to participants. It aims to bridge the gap between a narrow, transaction-oriented account of avoiding exploitation and a broad account emphasizing obligations of reparation for historic injustices. We propose that relief of oppression might focus researchers' consideration of benefits on those that have some relevance to background conditions of injustice, and so elevate the priority of these benefits, in relation to others that might be considered and negotiated with participants, according to the degree to which the participating communities are constrained in their

Nanomechanical resonators and their applications in biological/chemical detection: Nanomechanics principles

International Nuclear Information System (INIS)

Eom, Kilho; Park, Harold S.; Yoon, Dae Sung; Kwon, Taeyun

2011-01-01

Recent advances in nanotechnology have led to the development of nano-electro-mechanical systems (NEMS) such as nanomechanical resonators, which have recently received significant attention from the scientific community. This is not only due to their capability of label-free detection of bio/chemical molecules at single-molecule (or atomic) resolution for future applications such as the early diagnosis of diseases like cancer, but also due to their unprecedented ability to detect physical quantities such as molecular weight, elastic stiffness, surface stress, and surface elastic stiffness for adsorbed molecules on the surface. Most experimental works on resonator-based molecular detection have been based on the principle that molecular adsorption onto a resonator surface increases the effective mass, and consequently decreases the resonant frequencies of the nanomechanical resonator. However, this principle is insufficient to provide fundamental insights into resonator-based molecular detection at the nanoscale; this is due to recently proposed novel nanoscale detection principles including various effects such as surface effects, nonlinear oscillations, coupled resonance, and stiffness effects. Furthermore, these effects have only recently been incorporated into existing physical models for resonators, and therefore the universal physical principles governing nanoresonator-based detection have not been completely described. Therefore, our objective in this review is to overview the current attempts to understand the underlying mechanisms in nanoresonator-based detection using physical models coupled to computational simulations and/or experiments. Specifically, we will focus on issues of special relevance to the dynamic behavior of nanoresonators and their applications in biological/chemical detection: the resonance behavior of micro/nanoresonators; resonator-based chemical/biological detection; physical models of various nanoresonators such as nanowires, carbon

Evolutionary multimodal optimization using the principle of locality

2012-01-01

The principle of locality is one of the most widely used concepts in designing computing systems. To explore the principle in evolutionary computation, crowding differential evolution is incorporated with locality for multimodal optimization. Instead of generating trial vectors randomly, the first method proposed takes advantage of spatial locality to generate trial vectors. Temporal locality is also adopted to help generate offspring in the second method proposed. Temporal and spatial locality are then applied together in the third method proposed. Numerical experiments are conducted to compare the proposed methods with the state-of-the-art methods on benchmark functions. Experimental analysis is undertaken to observe the effect of locality and the synergy between temporal locality and spatial locality. Further experiments are also conducted on two application problems. One is the varied-line-spacing holographic grating design problem, while the other is the protein structure prediction problem. The numerical results demonstrate the effectiveness of the methods proposed. © 2012 Elsevier Inc. All rights reserved.

Securing Canada’s Information-Technology Infrastructure: Context, Principles, and Focus Areas of Cybersecurity Research

Directory of Open Access Journals (Sweden)

Dan Craigen

2013-07-01

Full Text Available This article addresses the challenges of cybersecurity and ultimately the provision of a stable and resilient information-technology infrastructure for Canada and, more broadly, the world. We describe the context of current cybersecurity challenges by synthesizing key source material whose importance was informed by our own real-world experiences. Furthermore, we present a checklist of guiding principles to a unified response, complete with a set of action-oriented research topics that are linked to known operational limitations. The focus areas are used to drive the formulation of a unified and relevant research and experimental development program, thereby moving us towards a stable and resilient cyberinfrastructure. When cybersecurity is viewed as an inherently interdisciplinary problem of societal concern, we expect that fundamentally new research perspectives will emerge in direct response to domain-specific protection requirements for information-technology infrastructure. Purely technical responses to cybersecurity challenges will be inadequate because human factors are an inherent aspect of the problem. This article will interest managers and entrepreneurs. Senior management teams can assess new technical developments and product releases to fortify their current security solutions, while entrepreneurs can harness new opportunities to commercialize novel technology to solve a high-impact cybersecurity problem..

The principles of teratology: are they still true?

Friedman, Jan M

2010-10-01

James Wilson originally proposed a set of "Principles of Teratology" in 1959, the year before he helped to found the Teratology Society. By 1977, when these Principles were presented in a more definitive form in Wilson and Fraser's Handbook of Teratology, they had become a standard formulation of the basic tenets of the field. Wilson's Principles have continued to guide scientific research in teratology, and they are widely used in teaching. Recent advances in our knowledge of the molecular and cellular bases of embryogenesis serve only to provide a deeper understanding of the fundamental developmental mechanisms that underlie Wilson's Principles of Teratology. © 2010 Wiley-Liss, Inc.

Connection of scattering principles: a visual and mathematical tour

2012-01-01

Inverse scattering, Green's function reconstruction, focusing, imaging and the optical theorem are subjects usually studied as separate problems in different research areas. We show a physical connection between the principles because the equations that rule these scattering principles have a similar functional form. We first lead the reader through a visual explanation of the relationship between these principles and then present the mathematics that illustrates the link between the governing equations of these principles. Throughout this work, we describe the importance of the interaction between the causal and anti-causal Green's functions. (paper)

Fermat's principle in quantum gravitational optics

International Nuclear Information System (INIS)

Ahmadi, N; Nouri-Zonoz, M; Khoeini-Moghaddam, S

2008-01-01

Interactions incorporating the vacuum polarization effects in curved backgrounds modify the null cone structure in such a way that the photon trajectories would not be the space–time geodesics any longer. The gravitational birefringence introduced as a direct consequence of these effects will allow shifts in the photon velocities leading to polarization dependent superluminal propagation. Taking these effects into account, we study Fermat's principle in the context of the 1+3 (threading) formulation of the space–time decomposition. We find an expression for the modified space–time refractive index and show that it is proportional to the light cone correction to first order. Consequences of this modification for spatial light paths are considered

Qualitative biomechanical principles for application in coaching.

Knudson, Duane

2007-01-01

Many aspects of human movements in sport can be readily understood by Newtonian rigid-body mechanics. Many of these laws and biomechanical principles, however, are counterintuitive to a lot of people. There are also several problems in the application of biomechanics to sports, so the application of biomechanics in the qualitative analysis of sport skills by many coaches has been limited. Biomechanics scholars have long been interested in developing principles that facilitate the qualitative application of biomechanics to improve movement performance and reduce the risk of injury. This paper summarizes the major North American efforts to establish a set of general biomechanical principles of movement, and illustrates how principles can be used to improve the application of biomechanics in the qualitative analysis of sport technique. A coach helping a player with a tennis serve is presented as an example. The standardization of terminology for biomechanical principles is proposed as an important first step in improving the application ofbiomechanics in sport. There is also a need for international cooperation and research on the effectiveness of applying biomechanical principles in the coaching of sport techniques.

Core principles of evolutionary medicine: A Delphi study.

Grunspan, Daniel Z; Nesse, Randolph M; Barnes, M Elizabeth; Brownell, Sara E

2018-01-01

Evolutionary medicine is a rapidly growing field that uses the principles of evolutionary biology to better understand, prevent and treat disease, and that uses studies of disease to advance basic knowledge in evolutionary biology. Over-arching principles of evolutionary medicine have been described in publications, but our study is the first to systematically elicit core principles from a diverse panel of experts in evolutionary medicine. These principles should be useful to advance recent recommendations made by The Association of American Medical Colleges and the Howard Hughes Medical Institute to make evolutionary thinking a core competency for pre-medical education. The Delphi method was used to elicit and validate a list of core principles for evolutionary medicine. The study included four surveys administered in sequence to 56 expert panelists. The initial open-ended survey created a list of possible core principles; the three subsequent surveys winnowed the list and assessed the accuracy and importance of each principle. Fourteen core principles elicited at least 80% of the panelists to agree or strongly agree that they were important core principles for evolutionary medicine. These principles over-lapped with concepts discussed in other articles discussing key concepts in evolutionary medicine. This set of core principles will be helpful for researchers and instructors in evolutionary medicine. We recommend that evolutionary medicine instructors use the list of core principles to construct learning goals. Evolutionary medicine is a young field, so this list of core principles will likely change as the field develops further.

The Principle of Polyrepresentation: Document Representations Created by Different Agents

Directory of Open Access Journals (Sweden)

Dora Rubinić

2015-03-01

Full Text Available Abstract Purpose:The paper gives a review of literature on the principle of polyrepresentation formulated by Ingwersen in the nineties of the 20th century. The principle of polyrepresentation points out the necessity of existence of different cognitive and functional representations of the same document, created by different agents in order to answer to different representations of user’s needs. The main goal of the paper is to give an overview of the principle of polyrepresentation as well as the translation of terms into Croatian which provides an opportunity for further development of terminology of related areas, e.g. information retrieval, subject indexing etc. Methodology/approach: The method used in this paper is the analysis of selected research papers on development of the principle of polyrepresentation. The literature was selected due to its importance and approach to the topic and was limited to papers mostly dealing with subject access to documents.Research limitation: The review was limited to just one aspect of the model – the representations of documents. The second part of the model – the cognitive sphere and its application in IR systems was excluded from this paper.Originality/practical implications: The paper implies the importance of the principle of polyrepresentation in the context of current trends in subject indexing in online systems. Although there is a number of articles referring to the principle, as well as some empirical researches using some elements of the principle, subject access of it is often not included in them. This paper emphasizes the importance of the principle primarily in the context of current trends in subject indexing used in online systems (e. g. use of subject headings or access points in online catalogues, social tagging, including different agents involved in subject indexing online etc.. It also recommends translations of selected terms into Croatian and invites researchers to discuss

Ethical use of social media to facilitate qualitative research.

2015-01-01

Increasingly, qualitative health researchers might consider using social media to facilitate communication with participants. Ambiguity surrounding the potential risks intrinsic to social media could hinder ethical conduct and discourage use of this innovative method. We used some core principles of traditional human research ethics, that is, respect, integrity, and beneficence, to design our photo elicitation research that explored the social influences of drinking alcohol among 34 underage women in metropolitan South Australia. Facebook aided our communication with participants, including correspondence ranging from recruitment to feeding back results and sharing research data. This article outlines the ethical issues we encountered when using Facebook to interact with participants and provides guidance to researchers planning to incorporate social media as a tool in their qualitative studies. In particular, we raise the issues of privacy and confidentiality as contemporary risks associated with research using social media. © The Author(s) 2014.

Copernicus, Kant, and the anthropic cosmological principles

Science.gov (United States)

Roush, Sherrilyn

In the last three decades several cosmological principles and styles of reasoning termed 'anthropic' have been introduced into physics research and popular accounts of the universe and human beings' place in it. I discuss the circumstances of 'fine tuning' that have motivated this development, and what is common among the principles. I examine the two primary principles, and find a sharp difference between these 'Weak' and 'Strong' varieties: contrary to the view of the progenitors that all anthropic principles represent a departure from Copernicanism in cosmology, the Weak Anthropic Principle is an instance of Copernicanism. It has close affinities with the step of Copernicus that Immanuel Kant took himself to be imitating in the 'critical' turn that gave rise to the Critique of Pure Reason. I conclude that the fact that a way of going about natural science mentions human beings is not sufficient reason to think that it is a subjective approach; in fact, it may need to mention human beings in order to be objective.

A structured policy review of the principles of professional self-regulation.

Science.gov (United States)

Benton, D C; González-Jurado, M A; Beneit-Montesinos, J V

2013-03-01

The International Council of Nurses (ICN) has, for many years, based its work on professional self-regulation on a set of 12 principles. These principles are research based and were identified nearly three decades ago. ICN has conducted a number of reviews of the principles; however, changes have been minimal. In the past 5-10 years, a number of authors and governments, often as part of the review of regulatory systems, have started to propose principles to guide the way regulatory frameworks are designed and implemented. These principles vary in number and content. This study examines the current policy literature on principle-based regulation and compares this with the set of principles advocated by the ICN. A systematic search of the literature on principle-based regulation is used as the basis for a qualitative thematic analysis to compare and contrast the 12 principles of self-regulation with more recently published work. A mapping of terms based on a detailed description of the principles used in the various research and policy documents was generated. This mapping forms the basis of a critique of the current ICN principles. A professional self-regulation advocated by the ICN were identified. A revised and extended set of 13 principles is needed if contemporary developments in the field of regulatory frameworks are to be accommodated. These revised principles should be considered for adoption by the ICN to underpin their advocacy work on professional self-regulation. © 2013 The Authors.

Principles of Waterfront Renovation to Decisive Spaces for Local Identity: A Study Case of Port Adelaide, South Australia

Science.gov (United States)

Taher, S.; Haqi, F. I.

2017-07-01

If governments have an objective to participate in a globalized economy, they should address the challenges of blighted inner city and particularly older water front areas. In doing the latter there is often a degree of consistency in place making. While the processes and principles behind urban design and planning need to have an internal logic across different scales to create quality public realms, the outcome of these interventions are frequently unresponsive to regional diversities in culture and identity. This indifference can lead to changes in the built form through urban regeneration activities that do not respect, celebrate or represent the history and traditions of the local community associated with an inner harbour or other forms of urban waterfronts. This research was undertaken to develop a set of design principles for the Inner Harbour renewal project in Port Adelaide, South Australia that would be sensitive to the historical role of the water front and in particular to incorporate the sentiments and needs of long term residents for whom the character of the area and their attachment to it shapes their sense of identity. The research established a theoretical framework for the development of design principles such as functionality, accessibility, natural environment and culture, history and memory. The findings showed that the redevelopment did not significantly disrupt residents’ sense of place or sense of local identity however some more additional design attributes would nevertheless strengthen the capacity of the project to preserve local identity. This paper concludes with recommendations for preserving local identity for residents adjacent to waterfront renewal projects.

With the advent of microprocessors and digital-processing technologies as catalyst, classical sensors capable of simple signal conditioning operations have evolved rapidly to take on higher and more specialized functions including validation, compensation, and classification. This new category of sensor expands the scope of incorporating intelligence into instrumentation systems, yet with such rapid changes, there has developed no universal standard for design, definition, or requirement with which to unify intelligent instrumentation. Explaining the underlying design methodologies of intelligent instrumentation, Intelligent Instrumentation: Principles and Applications provides a comprehensive and authoritative resource on the scientific foundations from which to coordinate and advance the field. Employing a textbook-like language, this book translates methodologies to more than 80 numerical examples, and provides applications in 14 case studies for a complete and working understanding of the material.

We introduce a naturally-defined totally invariant spacetime energy expression for general relativity incorporating the contribution from gravity. The extension links seamlessly to the action integral for the gravitational field. The demand that the general expression for arbitrary systems reduces to the Tolman integral in the case of stationary bounded distributions, leads to the matter-localized Ricci integral for energy–momentum in support of the energy localization hypothesis. The role of the observer is addressed and as an extension of the special relativistic case, the field of observers comoving with the matter is seen to compute the intrinsic global energy of a system. The new localized energy supports the Bonnor claim that the Szekeres collapsing dust solutions are energy-conserving. It is suggested that in the extreme of strong gravity, the Heisenberg Uncertainty Principle be generalized in terms of spacetime energy–momentum. -- Highlights: •We present a totally invariant spacetime energy expression for general relativity incorporating the contribution from gravity. •Demand for the general expression to reduce to the Tolman integral for stationary systems supports the Ricci integral as energy–momentum. •Localized energy via the Ricci integral is consistent with the energy localization hypothesis. •New localized energy supports the Bonnor claim that the Szekeres collapsing dust solutions are energy-conserving. •Suggest the Heisenberg Uncertainty Principle be generalized in terms of spacetime energy–momentum in strong gravity extreme.

Science.gov (United States)

Kostenko, Viktoriia G; Solohor, Iryna M

2018-01-01

Introduction: Medical researchers, who are non-native English speakers, are facing now the growing need to publish their research results in international journals switching to an English-only policy, to apply for grants and scholarship, but at the same time this puts many authors whose native language is not English at a disadvantage compared to their English-speaking counterparts. The aim: This paper aims at analysing the existing parameters of academic writing proficiency of medical undergraduate and postgraduate students; elucidating current approaches to develop academic writing competency and to promote academic multi-literacy of junior researchers, and outlining the general recommendations to improve the quality and sophistication of their writing by incorporating the principles and achievements of academic writing pedagogy into the system of medical training. Materials and methods: This study is an empirical applied research of a qualitative type mainly based on data elicited from informants (n=120) of the Ukrainian Medical Stomatological Academy aged from 20 - 35. Results and conclusions: All participants were able to identify personal problem areas, and virtually all they note dissatisfaction with the use of English in their scholarly writing. They stated the obvious difficulties in sentence patterns and keeping tone of scientific narrative format. Writing in genres other than original research articles seems to be quite demanding and is often associated with the lack of self-confidence and language anxiety. Attention to developing academic writing skills should focus on the basic elements of academic writing, characteristics of written genres across the disciplines, providing a framework in which expert and practical knowledge is internally organized.

Smart labels in municipal solid waste - a case for the Precautionary Principle?

International Nuclear Information System (INIS)

Waeger, P.A.; Eugster, M.; Hilty, L.M.; Som, C.

2005-01-01

The Precautionary Principle aims at anticipating and minimizing potentially serious or irreversible risks under conditions of uncertainty. Although it has been incorporated into many international treaties and pieces of national legislation for environmental protection and sustainable development, the Precautionary Principle has rarely been applied to novel Information and Communication Technologies (ICT) and their potential environmental impacts. In this article we analyze the implications of the disposal and recycling of packaging materials containing so-called smart labels and discuss the results from the perspective of the Precautionary Principle. We argue that a broad application of smart labels bears some risk of dissipating both toxic and valuable substances, and of disrupting established recycling processes. However, these risks can be avoided by precautionary measures, mainly concerning the composition and the use of smart labels. These measures should be implemented as early as possible in order to avoid irreversible developments which are undesirable from the viewpoint of resource management and environmental protection

Indeterminacy and the principle of need.

Science.gov (United States)

Herlitz, Anders

2017-02-01

The principle of need-the idea that resources should be allocated according to need-is often invoked in priority setting in the health care sector. In this article, I argue that a reasonable principle of need must be indeterminate, and examine three different ways that this can be dealt with: appendicizing the principle with further principles, imposing determinacy, or empowering decision makers. I argue that need must be conceptualized as a composite property composed of at least two factors: health shortfall and capacity to benefit. When one examines how the different factors relate to each other, one discovers that this is sometimes indeterminate. I illustrate this indeterminacy in this article by applying the small improvement argument. If the relation between the factors are always determinate, the comparative relation changes by a small adjustment. Yet, if two needs are dissimilar but of seemingly equal magnitude, the comparative relation does not change by a small adjustment of one of the factors. I then outline arguments in favor of each of the three strategies for dealing with indeterminacy, but also point out that all strategies have significant shortcomings. More research is needed concerning how to deal with this indeterminacy, and the most promising path seems to be to scrutinize the position of the principle of need among a plurality of relevant principles for priority setting in the health care sector.

2017-12-01

Background Undergraduate nursing education standards include acquisition of knowledge of ethics principles and the prevalence of health-care ethical dilemmas mandates that nursing students study ethics. However, little research has been published to support best practices for teaching/learning ethics principles. Purpose This study sought to determine if participation in an ethics consultation simulation increased nursing students' knowledge of nursing ethics principles compared to students who were taught ethics principles in the traditional didactic format. Methods This quasi-experimental study utilized a pre-test/post-test design with randomized assignment of students at three universities into both control and experimental groups. Results Nursing students' knowledge of nursing ethics principles significantly improved from pre-test to post-test ( p = .002); however, there was no significant difference between the experimental and control groups knowledge scores ( p = .13). Conclusion Further research into use of simulation to teach ethics principles is indicated.

A first-principles generic methodology for representing the knowledge base of a process diagnostic expert system

International Nuclear Information System (INIS)

Reifman, J.; Briggs, L.L.; Wei, T.Y.C.

1990-01-01

In this paper we present a methodology for identifying faulty component candidates of process malfunctions through basic physical principles of conservation, functional classification of components and information from the process schematics. The basic principles of macroscopic balance of mass, momentum and energy in thermal hydraulic control volumes are applied in a novel approach to incorporate deep knowledge into the knowledge base. Additional deep knowledge is incorporated through the functional classification of process components according to their influence in disturbing the macroscopic balance equations. Information from the process schematics is applied to identify the faulty component candidates after the type of imbalance in the control volumes is matched against the functional classification of the components. Except for the information from the process schematics, this approach is completely general and independent of the process under consideration. The use of basic first-principles, which are physically correct, and the process-independent architecture of the diagnosis procedure allow for the verification and validation of the system. A prototype process diagnosis expert system is developed and a test problem is presented to identify faulty component candidates in the presence of a single failure in a hypothetical balance of plant of a liquid metal nuclear reactor plant

Principles of neural information processing

2016-01-01

In this fundamental book the authors devise a framework that describes the working of the brain as a whole. It presents a comprehensive introduction to the principles of Neural Information Processing as well as recent and authoritative research. The books´ guiding principles are the main purpose of neural activity, namely, to organize behavior to ensure survival, as well as the understanding of the evolutionary genesis of the brain. Among the developed principles and strategies belong self-organization of neural systems, flexibility, the active interpretation of the world by means of construction and prediction as well as their embedding into the world, all of which form the framework of the presented description. Since, in brains, their partial self-organization, the lifelong adaptation and their use of various methods of processing incoming information are all interconnected, the authors have chosen not only neurobiology and evolution theory as a basis for the elaboration of such a framework, but also syst...

The precautionary principle as a provisional instrument in environmental policy: The Montreal Protocol case study

International Nuclear Information System (INIS)

Jacobs, J. Roger

2014-01-01

based. Many of these scientists act both as “honest brokers” and “issue advocates”, and through their shared interest in policy, may act to narrow the range of policy options. For example, modelled projections of low certainty are reported by Montreal Protocol contributing organisations to promote the importance of adhering to the Montreal Protocol. More comprehensive models of atmospheric chemistry incorporate more factors with interdependencies between variables. Consequently, outcomes projecting high risk and greater uncertainty are projected. As new reports of uncertain risk are propagated by studies from contributing organisations, continued application of the Precautionary Principle is required. The Montreal Protocol case suggests that when environmental studies introduce new concerns that trigger a policy response, the Precautionary Principle will act to perpetuate the research activity of contributing organisations, and extend the implementation of precautionary measures. Given the self-renewing nature this process, the precautionary measures are then not provisional

Qureshi, Uzma

The focus of this research project was the investigation of the functional properties of thin films that incorporate a secondary nanoparticulate phase. In particular to assess if the secondary nanoparticulate material enhanced a functional property of the coating on glass. In order to achieve this, new thin film deposition methods were developed, namely use of nanopowder precursors, an aerosol assisted transport technique and an aerosol into atmospheric pressure chemical vapour deposition system. Aerosol assisted chemical vapour deposition (AACVD) was used to deposit 8 series of thin films on glass. Five different nanoparticles silver, gold, ceria, tungsten oxide and zinc oxide were tested and shown to successfully deposit thin films incorporating nanoparticles within a host matrix. Silver nanoparticles were synthesised and doped within a titania film by AACVD. This improved solar control properties. A unique aerosol assisted chemical vapour deposition (AACVD) into atmospheric pressure chemical vapour deposition (APCVD) system was used to deposit films of Au nanoparticles and thin films of gold nanoparticles incorporated within a host titania matrix. Incorporation of high refractive index contrast metal oxide particles within a host film altered the film colour. The key goal was to test the potential of nanopowder forms and transfer the suspended nanopowder via an aerosol to a substrate in order to deposit a thin film. Discrete tungsten oxide nanoparticles or ceria nanoparticles within a titanium dioxide thin film enhanced the self-cleaning and photo-induced super-hydrophilicity. The nanopowder precursor study was extended by deposition of zinc oxide thin films incorporating Au nanoparticles and also ZnO films deposited from a ZnO nanopowder precursor. Incorporation of Au nanoparticles within a VO: host matrix improved the thermochromic response, optical and colour properties. Composite VC/TiC and Au nanoparticle/V02/Ti02 thin films displayed three useful

2016-02-01

This article considers the potential benefits that applying design principles from contemporary video games may have on enhancing therapy experiences. Six principles of video game design are presented, and their relevance for enriching clinical experiences is discussed. The motivational and learning benefits of each design principle have been discussed in the education literature as having positive impacts on student motivation and learning and are related here to aspects of clinical practice. The essential experience principle suggests connecting all aspects of the experience around a central emotion or cognitive connection. The discovery principle promotes indirect learning in focused environments. The risk-taking principle addresses the uncertainties clients face when attempting newly learned skills in novel situations. The generalization principle encourages multiple opportunities for skill transfer. The reward system principle directly relates to the scaffolding of frequent and varied feedback in treatment. Last, the identity principle can assist clients in using their newly learned communication skills to redefine self-perceptions. These principles highlight areas for research and interventions that may be used to reinforce or advance current practice.

2015-10-01

Shariah stock investing has become a widely discussed topic in financial industry as part of today's investment strategy. The strategy primarily applies market capitalization allocations. However, some researchers have argued that market capitalization weighting is inherently flawed and have advocated replacing market capitalization allocations with factor allocations. In this paper, we discuss the rationale for factor investing based on Musharakah principle. The essential elements or factors of Musharakah principle such as business sector, management capability, profitability growth and capital efficiency are embedded in the Shariah-compliant stock. We then transform these factors into indexation for better analysis and performance measurement. Investment universe for this research covers Malaysian stocks for the period of January 2009 to December 2013. We found out that these factor indexes have historically earned excess returns over market capitalization weighted indexes and experienced higher Sharpe Ratios.

Incorporating global components into ethics education.

Wang, George; Thompson, Russell G

2013-03-01

Ethics is central to science and engineering. Young engineers need to be grounded in how corporate social responsibility principles can be applied to engineering organizations to better serve the broader community. This is crucial in times of climate change and ecological challenges where the vulnerable can be impacted by engineering activities. Taking a global perspective in ethics education will help ensure that scientists and engineers can make a more substantial contribution to development throughout the world. This paper presents the importance of incorporating the global and cross culture components in the ethic education. The authors bring up a question to educators on ethics education in science and engineering in the globalized world, and its importance, necessity, and impendency. The paper presents several methods for discussion that can be used to identify the differences in ethics standards and practices in different countries; enhance the student's knowledge of ethics in a global arena.

Five principles for the practice of knowledge exchange in environmental management.

Science.gov (United States)

Reed, M S; Stringer, L C; Fazey, I; Evely, A C; Kruijsen, J H J

2014-12-15

This paper outlines five principles for effective practice of knowledge exchange, which when applied, have the potential to significantly enhance the impact of environmental management research, policy and practice. The paper is based on an empirical analysis of interviews with 32 researchers and stakeholders across 13 environmental management research projects, each of which included elements of knowledge co-creation and sharing in their design. The projects focused on a range of upland and catchment management issues across the UK, and included Research Council, Government and NGO funded projects. Preliminary findings were discussed with knowledge exchange professionals and academic experts to ensure the emerging principles were as broadly applicable as possible across multiple disciplines. The principles suggest that: knowledge exchange needs to be designed into research; the needs of likely research users and other stakeholders should be systematically represented in the research where possible; and long-term relationships must be built on trust and two-way dialogue between researchers and stakeholders in order to ensure effective co-generation of new knowledge. We found that the delivery of tangible benefits early on in the research process helps to ensure continued motivation and engagement of likely research users. Knowledge exchange is a flexible process that must be monitored, reflected on and continuously refined, and where possible, steps should be taken to ensure a legacy of ongoing knowledge exchange beyond initial research funding. The principles have been used to inform the design of knowledge exchange and stakeholder engagement guidelines for two international research programmes. They are able to assist researchers, decision-makers and other stakeholders working in contrasting environmental management settings to work together to co-produce new knowledge, and more effectively share and apply existing knowledge to manage environmental change

An Analysis of Yusuf (AS's Counter-Cyclical Principle and its Implementation in the Modern World

Directory of Open Access Journals (Sweden)

Jameel Ahmed

2014-03-01

Full Text Available Objective - This study examines the present-day implementation of the counter-cyclical principle suggested by Yusuf (AS around four thousand years ago, in response to the King of Egypt's dream, to overcome the famine of seven years through saving grain during seven years of abundance. In general, the counter-cyclical principle encourages saving during times of plenty and spending during times of scarcity, activities which today help to stabilise the business-cycle.Method - Library research is applied since this paper relies on secondary data by thoroughly reviewing the most relevant literature. This paper reviews the commodity-based currency systems proposed before, during and after the Second World War by several prominent economists (particularly Keynes, 1938; Graham, 1940; Hayek, 1943; Grondona, 1950 and Lietaer, 2001 all of which basically incorporated the counter-cyclical principle of Prophet Yusuf (AS. The primary purpose of these commodity-based currency systems is to stabilise the real value of money in order to improve macroeconomic stability. Additionally, this paper provides an in-depth analysis of Grondona system of conditional currency convertibility.Results - The Grondona system would partially stabilise the real value of each country's national currency in terms of a range of durable, essential, basic imported commodities, thereby also partially stabilising the prices of the selected commodities in terms of the national currency of each country implementing the system.Conclusion - The Grondona system of conditional currency convertibility as compared to other commodity-based currency systems is more practical. Its primary advantage in comparison to other proposals of commodity reserve currency is that it could be implemented in parallel with the existing monetary system. Accordingly, it could be taken as a preliminary step towards a monetary system based on real money such as gold dinar.Keywords : Counter-cyclical principle

Bioethical Issues in Conducting Pediatric Dentistry Clinical Research.

Science.gov (United States)

Garrocho-Rangel, Arturo; Cerda-Cristerna, Bernardino; Pozos-Guillen, Amaury

Pediatric clinical research on new drugs and biomaterials involves children in order to create valid and generalizable knowledge. Research on vulnerable populations, such as children, is necessary but only admissible when researchers strictly follow methodological and ethical standards, together with the respect to human rights; and very especially when the investigation cannot be conducted with other population or when the potential benefits are specifically for that age group. Clinical research in Pediatric Dentistry is not an exception. The aim of the present article was to provide the bioethical principles (with respect to the child/parents' autonomy, benefit/risk analysis, and distributive justice), and recommendations, including informed consent, research ethics committees, conflict of interest, and the "equipoise" concept. Current and future worldwide oral health research in children and adolescents must be conducted incorporating their perspectives in the decision-making process as completely as possible. This concept must be carefully considered when a dental clinical study research is going to be planned and conducted, especially in the case of randomized controlled trials, in which children will be recruited as participants.

Moving towards a more inclusive patient and public involvement in health research paradigm: the incorporation of a trauma-informed intersectional analysis.

Shimmin, Carolyn; Wittmeier, Kristy D M; Lavoie, Josée G; Wicklund, Evan D; Sibley, Kathryn M

2017-08-07

The concept of patient engagement in health research has received growing international recognition over recent years. Yet despite some critical advancements, we argue that the concept remains problematic as it negates the very real complexities and context of people's lives. Though patient engagement conceptually begins to disrupt the identity of "researcher," and complicate our assumptions and understandings around expertise and knowledge, it continues to essentialize the identity of "patient" as a homogenous group, denying the reality that individuals' economic, political, cultural, subjective and experiential lives intersect in intricate and multifarious ways. Patient engagement approaches that do not consider the simultaneous interactions between different social categories (e.g. race, ethnicity, Indigeneity, gender, class, sexuality, geography, age, ability, immigration status, religion) that make up social identity, as well as the impact of systems and processes of oppression and domination (e.g. racism, colonialism, classism, sexism, ableism, homophobia) exclude the involvement of individuals who often carry the greatest burden of illness - the very voices traditionally less heard in health research. We contend that in order to be a more inclusive and meaningful approach that does not simply reiterate existing health inequities, it is important to reconceptualize patient engagement through a health equity and social justice lens by incorporating a trauma-informed intersectional analysis. This article provides key concepts to the incorporation of a trauma-informed intersectional analysis and important questions to consider when developing a patient engagement strategy in health research training, practice and evaluation. In redefining the identity of both "patient" and "researcher," spaces and opportunities to resist and renegotiate power within the intersubjective relations can be recognized and addressed, in turn helping to build trust, transparency and

Full Text Available This research describes a resonance principle-based low power Wireless Power Transfer (WPT system. The reflective impedance model is derived to evaluate the resonance coupling between coils. Additionally, Cockroft Walton voltage boosting circuit is incorporated to boost up the received voltage to the appropriate level, instead of using traditional conditioning circuits. The prototype model, operating at 130 kHz, is demonstrated experimentally and analysed graphically to validate the performance of designed circuit. For an overall span of 100 mm coil separation distance, the maximum efficiency of 60% with no load and 36% loaded system, is observed at a distance of 55 mm with the approximate (e.g., manual axial orientation of coils. It can be supported widely for the portable electronic products and biomedical devices. As an added contribution, the WPT circuit were enabled by a password security feature using an arduino nicrocontroller.

The Antidiscrimination Principle and the Determination of Disadvantage

MARÍA JOSÉ AÑÓN

2014-06-01

Full Text Available This paper examines some of the limits of antidiscrimination law in its present form, focusing on the major trends that underlie it from the perspective of legislation and case law. It reflects on the traditional principles of interpretation and the impediments to incorporating standards offering both justification and explanation in the test of equality; standards that might detect the patterns or social structures of discrimination and identify individuals with greater accuracy. To this end, it proposes to further develop the debate on indirect discrimination and material equality through additional interpretative criteria that originate in categories such as structural discrimination and the intersectionality of discrimination.

Achieving enhanced organisational resilience by improved management of risk: Summary of research into the principles of resilience and the practices of resilient organisations.

Science.gov (United States)

Hopkin, Paul

There have been many high-profile incidents in recent times that have affected both individual organisations and large parts of society. In response to these disasters and their consequences, there has been increasing focus on the concept of 'resilience'. Airmic worked with Cranfield School of Management to investigate the features of resilient organisations and whether common characteristics could be identified. The research summarised in this paper discovered five principles that increase an organisation's level of resilence. The paper also reports on the actions taken by organisations to embed these resilience principles into four main business enablers. These business enablers in combination represent the business model of the organisation. The overall conclusion of the research was that, in order to achieve a state of enhanced resilience, organisations need to be aware of risks and threats they face and then combine the actions required to be 'risk compliant' with the ability to be 'risk responsive'.

Passarella, P M; Lewis, N

1987-04-01

The nursing approach in the care of stroke patients has a direct impact on functional outcome. Nursing application of Bobath principles in stroke care offers a nursing focus on involvement of the affected side; facilitation of normal tone, posture, and movement; and development of more normal function. A research study evaluating the functional gains of stroke patients demonstrated a significant level of functional improvement in those treated with Bobath principles over stroke patients treated with the traditional nursing approach. Practical methods for applying Bobath principles in patient care activities are described. These therapeutic methods provide nurses with the means to maximize stroke patients' potential and further influence their functional recovery.

A review of human factors principles for the design and implementation of medication safety alerts in clinical information systems.

Science.gov (United States)

Phansalkar, Shobha; Edworthy, Judy; Hellier, Elizabeth; Seger, Diane L; Schedlbauer, Angela; Avery, Anthony J; Bates, David W

2010-01-01

The objective of this review is to describe the implementation of human factors principles for the design of alerts in clinical information systems. First, we conduct a review of alarm systems to identify human factors principles that are employed in the design and implementation of alerts. Second, we review the medical informatics literature to provide examples of the implementation of human factors principles in current clinical information systems using alerts to provide medication decision support. Last, we suggest actionable recommendations for delivering effective clinical decision support using alerts. A review of studies from the medical informatics literature suggests that many basic human factors principles are not followed, possibly contributing to the lack of acceptance of alerts in clinical information systems. We evaluate the limitations of current alerting philosophies and provide recommendations for improving acceptance of alerts by incorporating human factors principles in their design.

Seven Foundational Principles of Population Health Policy.

Science.gov (United States)

Bhattacharya, Dru; Bhatt, Jay

2017-10-01

In 2016, Keyes and Galea issued 9 foundational principles of population health science and invited further deliberations by specialists to advance the field. This article presents 7 foundational principles of population health policy whose intersection with health care, public health, preventive medicine, and now population health, presents unique challenges. These principles are in response to a number of overarching questions that have arisen in over a decade of the authors' collective practice in the public and private sectors, and having taught policy within programs of medicine, law, nursing, and public health at the graduate and executive levels. The principles address an audience of practitioners and policy makers, mindful of the pressing health care challenges of our time, including: rising health-related expenditures, an aging population, workforce shortages, health disparities, and a backdrop of inequities rooted in social determinants that have not been adequately translated into formal policies or practices among the key stakeholders in population health. These principles are meant to empower stakeholders-whether it is the planner or the practitioner, the decision maker or the dedicated caregiver-and inform the development of practical tools, research, and education.

Stressing the self-determination of the elderly and the help provided as service is potentially at odds with one of the existing principles of elderly care, namely the professional principle of help-to-self help. It aims at activating...... the elderly person to manage as much as possible themselves and is based upon a socio-pedagogical culture, where the professional is teaching elderly people about the proper behavior. It’s based upon a formal knowledge of aging and upon different techniques to motivate and involve the elderly....... These are clearly different logics. However, no research has so far studied how these concepts are translated from a national to the municipal level to groups of home helpers and to individual home helpers. And how are these principles played out in different contexts of private firms and public providers...

Predictive minimum description length principle approach to inferring gene regulatory networks.

Chaitankar, Vijender; Zhang, Chaoyang; Ghosh, Preetam; Gong, Ping; Perkins, Edward J; Deng, Youping

2011-01-01

Reverse engineering of gene regulatory networks using information theory models has received much attention due to its simplicity, low computational cost, and capability of inferring large networks. One of the major problems with information theory models is to determine the threshold that defines the regulatory relationships between genes. The minimum description length (MDL) principle has been implemented to overcome this problem. The description length of the MDL principle is the sum of model length and data encoding length. A user-specified fine tuning parameter is used as control mechanism between model and data encoding, but it is difficult to find the optimal parameter. In this work, we propose a new inference algorithm that incorporates mutual information (MI), conditional mutual information (CMI), and predictive minimum description length (PMDL) principle to infer gene regulatory networks from DNA microarray data. In this algorithm, the information theoretic quantities MI and CMI determine the regulatory relationships between genes and the PMDL principle method attempts to determine the best MI threshold without the need of a user-specified fine tuning parameter. The performance of the proposed algorithm is evaluated using both synthetic time series data sets and a biological time series data set (Saccharomyces cerevisiae). The results show that the proposed algorithm produced fewer false edges and significantly improved the precision when compared to existing MDL algorithm.

Complex Correspondence Principle

International Nuclear Information System (INIS)

Bender, Carl M.; Meisinger, Peter N.; Hook, Daniel W.; Wang Qinghai

2010-01-01

Quantum mechanics and classical mechanics are distinctly different theories, but the correspondence principle states that quantum particles behave classically in the limit of high quantum number. In recent years much research has been done on extending both quantum and classical mechanics into the complex domain. These complex extensions continue to exhibit a correspondence, and this correspondence becomes more pronounced in the complex domain. The association between complex quantum mechanics and complex classical mechanics is subtle and demonstrating this relationship requires the use of asymptotics beyond all orders.

The principles and technical aspects of track formation in insulating solids are first described. The characteristics of dialectic track detection are discussed from the technical point of view: the nature of the detectors, the chemical treatment, the sensitivity and the environmental conditions of use. The applications are reviewed. The principle of each type of applied research is described and then the applications are listed. When used as a detector, nuclear tracks can provide valuable information in a number of fields: element content determination and wrapping, imaging, radiation dosimetry, environmental studies, technological uses and miscellaneous other applications. The track-formation process can also be used for making well-defined holes; this method allows other applications which are also described. Finally, some possible future applications are mentioned.

Shirley, S; Stampfl, R

1997-12-01

The purpose of this explanatory and prescriptive article is to identify interdisciplinary theories used by hospital development to direct its practice. The article explores, explains, and applies theories and principles from behavioral, social, and managerial disciplines. Learning, motivational, organizational, marketing, and attitudinal theories are incorporated and transformed into the fundamental components of a conceptual framework that provides an overview of the practice of hospital development. How this discipline incorporates these theories to design, explain, and prescribe the focus of its own practice is demonstrated. This interdisciplinary approach results in a framework for practice that is adaptable to changing social, cultural, economic, political, and technological environments.

Expanding Uncertainty Principle to Certainty-Uncertainty Principles with Neutrosophy and Quad-stage Method

Directory of Open Access Journals (Sweden)

2015-03-01

Full Text Available The most famous contribution of Heisenberg is uncertainty principle. But the original uncertainty principle is improper. Considering all the possible situations (including the case that people can create laws and applying Neutrosophy and Quad-stage Method, this paper presents "certainty-uncertainty principles" with general form and variable dimension fractal form. According to the classification of Neutrosophy, "certainty-uncertainty principles" can be divided into three principles in different conditions: "certainty principle", namely a particle’s position and momentum can be known simultaneously; "uncertainty principle", namely a particle’s position and momentum cannot be known simultaneously; and neutral (fuzzy "indeterminacy principle", namely whether or not a particle’s position and momentum can be known simultaneously is undetermined. The special cases of "certain ty-uncertainty principles" include the original uncertainty principle and Ozawa inequality. In addition, in accordance with the original uncertainty principle, discussing high-speed particle’s speed and track with Newton mechanics is unreasonable; but according to "certaintyuncertainty principles", Newton mechanics can be used to discuss the problem of gravitational defection of a photon orbit around the Sun (it gives the same result of deflection angle as given by general relativity. Finally, for the reason that in physics the principles, laws and the like that are regardless of the principle (law of conservation of energy may be invalid; therefore "certaintyuncertainty principles" should be restricted (or constrained by principle (law of conservation of energy, and thus it can satisfy the principle (law of conservation of energy.

The Precautionary Principle: implications for risk management strategies.

Science.gov (United States)

Saltelli, Andrea; Funtowicz, Silvio

2004-01-01

The European Commission has published a Communication on the Precautionary Principle and a White Book on Governance. These provide us (as research civil servants of the Commission) an institutional framework for handling scientific information that is often incomplete, uncertain, and contested. But, although the Precautionary Principle is intuitively straightforward to understand, there is no agreed way of applying it to real decision-making. To meet this perceived need, researchers have proposed a vast number of taxonomies. These include ignorance auditing, type one-two-three errors, a combination of uncertainty and decision stakes through post-normal science and the plotting of ignorance of probabilities against ignorance of consequences. Any of these could be used to define a precautionary principle region inside a multidimensional space and to position an issue within that region. The role of anticipatory research is clearly critical but scientific input is only part of the picture. It is difficult to imagine an issue where the application of the Precautionary Principle would be non-contentious. From genetically-modified food to electro-smog, from climate change to hormone growth in meat, it is clear that: 1) risk and cost-benefit are only part of the picture; 2) there are ethical issues involved; 3) there is a plurality of interests and perspectives that are often in conflict; 4) there will be losers and winners whatever decision is made. Operationalization of the Precautionary Principle must preserve transparency. Only in this way will the incommensurable costs and benefits associated with different stakeholders be registered. A typical decision will include the following sorts of considerations: 1) the commercial interests of companies and the communities that depend on them; 2) the worldviews of those who might want a greener, less consumerist society and/or who believe in the sanctity of human or animal life; 3) potential benefits such as enabling the

Radatz, Dana L; Wright, Emily M

2016-01-01

The majority of batterer intervention program (BIP) evaluations have indicated they are marginally effective in reducing domestic violence recidivism. Meanwhile, correctional programs used to treat a variety of offenders (e.g., substance users, violent offenders, and so forth) that adhere to the "principles of effective intervention" (PEI) have reported significant reductions in recidivism. This article introduces the PEI-the principles on which evidence-based practices in correctional rehabilitation are based-and identifies the degree to which they are currently integrated into BIPs. The case is made that batterer programs could be more effective if they incorporate the PEI. Recommendations for further integration of the principles into BIPs are also provided. © The Author(s) 2015.

Poor participant comprehension of research procedures following the conventional face-to-face consent process for biomedical research is common. We describe the development of a multimedia informed consent video and website that incorporates cognitive strategies to enhance comprehension of study related material directed to parents and adolescents. A multidisciplinary team was assembled for development of the video and website that included human subjects professionals; psychologist researchers; institutional video and web developers; bioinformaticians and programmers; and parent and adolescent stakeholders. Five learning strategies that included Sensory-Modality view, Coherence, Signaling, Redundancy, and Personalization were integrated into a 15-min video and website material that describes a clinical research trial. A diverse team collaborated extensively over 15months to design and build a multimedia platform for obtaining parental permission and adolescent assent for participant in as asthma clinical trial. Examples of the learning principles included, having a narrator describe what was being viewed on the video (sensory-modality); eliminating unnecessary text and graphics (coherence); having the initial portion of the video explain the sections of the video to be viewed (signaling); avoiding simultaneous presentation of text and graphics (redundancy); and having a consistent narrator throughout the video (personalization). Existing conventional and multimedia processes for obtaining research informed consent have not actively incorporated basic principles of human cognition and learning in the design and implementation of these processes. The present paper illustrates how this can be achieved, setting the stage for rigorous evaluation of potential benefits such as improved comprehension, satisfaction with the consent process, and completion of research objectives. New consent strategies that have an integrated cognitive approach need to be developed and

Ethical issues in research.

Science.gov (United States)

Artal, Raul; Rubenfeld, Sheldon

2017-08-01

Biomedical research is currently guided by ethical standards that have evolved over many centuries. Historical and political events, social and legal considerations, and continuous medical and technological advances have led to the prevailing research ethics and practice. Currently, patients and research subjects have complete autonomy while under medical care or when volunteering as research subjects. Enrolling volunteers in human subjects research includes a detailed and meaningful informed consent process that follows the cardinal principles of ethics: autonomy, beneficence, nonmaleficence, and justice. These principles were gradually adopted after World War II, primarily in response to the unethical behavior of German physicians and scientists during the Third Reich. This review emphasizes the importance of historical milestones and the essential role that ethics has in contemporary medical research. Research protocols should achieve maximum benefits for the society, have clinical and scientific value, be subject to independent review, respect human dignity, and follow the principles of informed consent, and most importantly, subjects should have complete autonomy. However, current principles and regulations cannot cover every conceivable situation, particularly in view of the new advances in science and technology. New and evolving medical technology, genetic research, therapeutic interventions, and innovations challenge society to maintain the highest moral and ethical principles. Copyright © 2017.

Samal, Janmejaya; Dehury, Ranjit Kumar

2017-06-01

Every year a noticeable number of MD and PhD students pass out from various Ayurveda colleges across the country. Each of these Post Graduate (PG) and doctoral students do submit a research thesis as a part of fulfillment of their respective degrees. As on 01/04/2015 there were 98 PG Ayurveda colleges in India with an admission capacity of 2441 seats each year. Moreover many of the post graduate institutes provide doctoral level (PhD) education which is primarily involved with research thesis. Such meticulous research carried out under the supervision of an academic expert should not go in vein and hence the research findings need to be slotted in to the respective areas and disciplines of Ayurveda syllabus. This will help in bringing in the latest scientific trends of Ayurveda to graduate students. Distressingly such practices are not in vogue in Ayurveda education system and most of the colleges follow the same stereotypic pedagogy using the classical texts of Ayurveda or their respective commentaries written decades back. Use of classical treatises and their respective commentaries offers very limited access to the recent scientific developments of Ayurveda as these commentaries are mostly one time efforts and do not undergo repeated revisions thus limiting the inclusion of present day innovations. In this commentary an effort has been made to understand the source, output, need and importance of such academic research finding with reference to their incorporation in to curricula of Ayurveda.

First-principles study of Mg incorporation at wurtzite InN (0 0 0 1) and (0001-bar) surfaces

International Nuclear Information System (INIS)

Ding, S.F.; Qu, X.P.; Fan, G.H.

2009-01-01

In this article we investigate the energetics of Mg adsorption and incorporation at the InN(0 0 0 1) and InN(0001-bar) surfaces by the method of total energy plane-wave expansions with ultra-soft pseudo potential technology based on the density functional theory (DFT) in the generalized approximation (GGA). It is found that for a 1/4 monolayer (ML) coverage of the InN(0 0 0 1) surface, Mg atoms preferentially adsorb at the bridge sites and T4 sites, but they are unstable when compared with Mg incorporated in the first three layers. For a 1/4 ML coverage of the InN(0001-bar) surface, Mg atoms preferentially adsorb at the H3 sites with the formation energy of -3.49 (eV/(2x2) supercell), which is lower than that of the T4 sites, and the formation energy increases with increasing magnesium coverage. Further study shows that the formation energy for Mg atom is lower than that of In atom, which indicates that magnesium adsorption is more favorable in these conditions.

Interactions incorporating the vacuum polarization effects in curved backgrounds modify the null cone structure in such a way that the photon trajectories would not be the space-time geodesics any longer. The gravitational birefringence introduced as a direct consequence of these effects will allow shifts in the photon velocities leading to polarization dependent superluminal propagation. Taking these effects into account, we study Fermat's principle in the context of the 1+3 (threading) formulation of the space-time decomposition. We find an expression for the modified space-time refractive index and show that it is proportional to the light cone correction to first order. Consequences of this modification for spatial light paths are considered.

Potential for Integrating Diffusion of Innovation Principles into Life Cycle Assessment of Emerging Technologies.

Science.gov (United States)

Sharp, Benjamin E; Miller, Shelie A

2016-03-15

Life cycle assessment (LCA) measures cradle-to-grave environmental impacts of a product. To assess impacts of an emerging technology, LCA should be coupled with additional methods that estimate how that technology might be deployed. The extent and manner that an emerging technology diffuses throughout a region shapes the magnitude and type of environmental impacts. Diffusion of innovation is an established field of research that analyzes the adoption of new innovations, and its principles can be used to construct scenario models that enhance LCA of emerging technologies. Integrating diffusion modeling techniques with an LCA of emerging technology can provide estimates for the extent of market penetration, the displacement of existing systems, and the rate of adoption. Two general perspectives of application are macro-level diffusion models that use a function of time to represent adoption, and microlevel diffusion models that simulate adoption through interactions of individuals. Incorporating diffusion of innovation concepts complement existing methods within LCA to inform proactive environmental management of emerging technologies.

Time-advance algorithms based on Hamilton's principle

International Nuclear Information System (INIS)

Lewis, H.R.; Kostelec, P.J.

1993-01-01

Time-advance algorithms based on Hamilton's variational principle are being developed for application to problems in plasma physics and other areas. Hamilton's principle was applied previously to derive a system of ordinary differential equations in time whose solution provides an approximation to the evolution of a plasma described by the Vlasov-Maxwell equations. However, the variational principle was not used to obtain an algorithm for solving the ordinary differential equations numerically. The present research addresses the numerical solution of systems of ordinary differential equations via Hamilton's principle. The basic idea is first to choose a class of functions for approximating the solution of the ordinary differential equations over a specific time interval. Then the parameters in the approximating function are determined by applying Hamilton's principle exactly within the class of approximating functions. For example, if an approximate solution is desired between time t and time t + Δ t, the class of approximating functions could be polynomials in time up to some degree. The issue of how to choose time-advance algorithms is very important for achieving efficient, physically meaningful computer simulations. The objective is to reliably simulate those characteristics of an evolving system that are scientifically most relevant. Preliminary numerical results are presented, including comparisons with other computational methods

The 'Herbivory Uncertainty Principle': application in a cerrado site

Directory of Open Access Journals (Sweden)

CA Gadotti

Full Text Available Researchers may alter the ecology of their studied organisms, even carrying out apparently beneficial activities, as in herbivory studies, when they may alter herbivory damage. We tested whether visit frequency altered herbivory damage, as predicted by the 'Herbivory Uncertainty Principle'. In a cerrado site, we established 80 quadrats, in which we sampled all woody individuals. We used four visit frequencies (high, medium, low, and control, quantifying, at the end of three months, herbivory damage for each species in each treatment. We did not corroborate the 'Herbivory Uncertainty Principle', since visiting frequency did not alter herbivory damage, at least when the whole plant community was taken into account. However, when we analysed each species separately, four out of 11 species presented significant differences in herbivory damage, suggesting that the researcher is not independent of its measurements. The principle could be tested in other ecological studies in which it may occur, such as those on animal behaviour, human ecology, population dynamics, and conservation.

Dimensional cosmological principles

International Nuclear Information System (INIS)

Chi, L.K.

1985-01-01

The dimensional cosmological principles proposed by Wesson require that the density, pressure, and mass of cosmological models be functions of the dimensionless variables which are themselves combinations of the gravitational constant, the speed of light, and the spacetime coordinates. The space coordinate is not the comoving coordinate. In this paper, the dimensional cosmological principle and the dimensional perfect cosmological principle are reformulated by using the comoving coordinate. The dimensional perfect cosmological principle is further modified to allow the possibility that mass creation may occur. Self-similar spacetimes are found to be models obeying the new dimensional cosmological principle

On the function and importance of research design in existential-phenomenological qualitative research

inquiry. This is very different from the research traditions within the social sciences, which traditionally emphasizes the importance of research design and a controlled inquiry, even with respect to qualitative research. Social research is traditionally divided into three phases: planning, execution...... in a convincing way. This principle of controlled inquiry manifests itself in different ways within qualitative and quantitative traditions of social science research. But still, is this principle also applicable and relevant with respect to qualitative human science research? I think so. I hence make...... the argument that there would be a fruitful contribution to much phenomenological research from a greater emphasis on research design and controlled inquiry. But is it possible to combine these social science research principles with a phenomenological and hermeneutical approach to qualitative research...

Benlamoudi, A.; Kadir, A. Abdul; Khodja, M.; Nuruddin, M. F.

2018-04-01

Very limited researches have been conducted on the incorporation of petroleum sludge waste into cement clinker production even though this waste may contain similar components to those of clinker raw materials. In this research, petroleum sludge was integrated into cement plant as raw material to produce the cement clinker. As results, incorporation of 5% of this waste was able to produce an acceptable quality of cement. Despite the use of petroleum sludge has decreased the properties of the produced clinker, but it still fit the requirements.

The foundational principles as psychological lodestars: Theoretical inspiration and empirical direction in rehabilitation psychology.

Dunn, Dana S; Ehde, Dawn M; Wegener, Stephen T

2016-02-01

Historically, the Foundational Principles articulated by Wright (1983) and others guided theory development, research and scholarship, and practice in rehabilitation psychology. In recent decades, these principles have become more implicit and less explicit or expressive in the writings and work of rehabilitation professionals. We believe that the Foundational Principles are essential lodestars for working with people with disabilities that can guide inquiry, practice, and service. To introduce this special issues, this commentary identifies and defines key Foundational Principles, including, for example, Lewin's (1935) person-environment relation, adjustment to disability, the malleability of self-perceptions of bodily states, and the importance of promoting dignity for people with disabilities. We then consider the role the Foundational Principles play in the articles appearing in this special issue. We close by considering some new principles and their potential utility in rehabilitation settings. Readers in rehabilitation psychology and aligned areas (e.g., social-personality psychology, health psychology, rehabilitation therapist, psychiatry, and nursing) are encouraged to consider how the Foundational Principles underlie and can shape their research and practice.

2016-01-01

We propose a consolidated risk measure based on variance and the safety-first principle in a mean-risk portfolio optimization framework. The safety-first principle to financial portfolio selection strategy is modified and improved. Our proposed models are subjected to norm regularization to seek near-optimal stable and sparse portfolios. We compare the cumulative wealth of our preferred proposed model to a benchmark, S&P 500 index for the same period. Our proposed portfolio strategies have better out-of-sample performance than the selected alternative portfolio rules in literature and control the downside risk of the portfolio returns.

Active videogames have the potential to enhance population levels of physical activity but have not been successful in achieving this aim to date. This article considers a range of principles that may be important to the design of effective and efficient active videogames from diverse discipline areas, including behavioral sciences (health behavior change, motor learning, and serious games), business production (marketing and sales), and technology engineering and design (human-computer interaction/ergonomics and flow). Both direct and indirect pathways to impact on population levels of habitual physical activity are proposed, along with the concept of a game use lifecycle. Examples of current active and sedentary electronic games are used to understand how such principles may be applied. Furthermore, limitations of the current usage of theoretical principles are discussed. A suggested list of principles for best practice in active videogame design is proposed along with suggested research ideas to inform practice to enhance physical activity.

Abstract Active videogames have the potential to enhance population levels of physical activity but have not been successful in achieving this aim to date. This article considers a range of principles that may be important to the design of effective and efficient active videogames from diverse discipline areas, including behavioral sciences (health behavior change, motor learning, and serious games), business production (marketing and sales), and technology engineering and design (human–computer interaction/ergonomics and flow). Both direct and indirect pathways to impact on population levels of habitual physical activity are proposed, along with the concept of a game use lifecycle. Examples of current active and sedentary electronic games are used to understand how such principles may be applied. Furthermore, limitations of the current usage of theoretical principles are discussed.

The principle of least action history and physics

CERN Document Server

Rojo, Alberto

2018-01-01

The principle of least action originates in the idea that, if nature has a purpose, it should follow a minimum or critical path. This simple principle, and its variants and generalizations, applies to optics, mechanics, electromagnetism, relativity, and quantum mechanics, and provides an essential guide to understanding the beauty of physics. This unique text provides an accessible introduction to the action principle across these various fields of physics, and examines its history and fundamental role in science. It includes - with varying levels of mathematical sophistication - explanations from historical sources, discussion of classic papers, and original worked examples. The result is a story that is understandable to those with a modest mathematical background, as well as to researchers and students in physics and the history of physics.

A New Principle in Physics: the Principle 'Finiteness', and Some Consequences

International Nuclear Information System (INIS)

Sternlieb, Abraham

2010-01-01

In this paper I propose a new principle in physics: the principle of 'finiteness'. It stems from the definition of physics as a science that deals (among other things) with measurable dimensional physical quantities. Since measurement results, including their errors, are always finite, the principle of finiteness postulates that the mathematical formulation of 'legitimate' laws of physics should prevent exactly zero or infinite solutions. Some consequences of the principle of finiteness are discussed, in general, and then more specifically in the fields of special relativity, quantum mechanics, and quantum gravity. The consequences are derived independently of any other theory or principle in physics. I propose 'finiteness' as a postulate (like the constancy of the speed of light in vacuum, 'c'), as opposed to a notion whose validity has to be corroborated by, or derived theoretically or experimentally from other facts, theories, or principles.

TPS has demonstrated increased efficiency and effectiveness, reduced cost, and enhanced achievement of stated goals. Drexel University is the first academic institution to incorporate the principles of the TPS into nursing education. Copyright © 2012 Elsevier Inc. All rights reserved.

Scaling symmetries, conservation laws and action principles in one-dimensional gas dynamics

International Nuclear Information System (INIS)

Webb, G M; Zank, G P

2009-01-01

Scaling symmetries of the planar, one-dimensional gas dynamic equations with adiabatic index γ are used to obtain Lagrangian and Eulerian conservation laws associated with the symmetries. The known Eulerian symmetry operators for the scaling symmetries are converted to the Lagrangian form, in which the Eulerian spatial position of the fluid element is given in terms of the Lagrangian fluid labels. Conditions for a linear combination of the three scaling symmetries to be a divergence or variational symmetry of the action are established. The corresponding Lagrangian and Eulerian form of the conservation laws are determined by application of Noether's theorem. A nonlocal conservation law associated with the scaling symmetries is obtained by applying a nonlocal symmetry operator to the scaling symmetry-conserved vector. An action principle incorporating known conservation laws using Lagrangian constraints is developed. Noether's theorem for the constrained action principle gives the same formulas for the conserved vector as the classical Noether theorem, except that the Lie symmetry vector field now includes the effects of nonlocal potentials. Noether's theorem for the constrained action principle is used to obtain nonlocal conservation laws. The scaling symmetry conservation laws only apply for special forms of the entropy of the gas.

Against proportional shortfall as a priority-setting principle.

Science.gov (United States)

Altmann, Samuel

2018-05-01

As the demand for healthcare rises, so does the need for priority setting in healthcare. In this paper, I consider a prominent priority-setting principle: proportional shortfall. My purpose is to argue that proportional shortfall, as a principle, should not be adopted. My key criticism is that proportional shortfall fails to consider past health.Proportional shortfall is justified as it supposedly balances concern for prospective health while still accounting for lifetime health, even though past health is deemed irrelevant. Accounting for this lifetime perspective means that the principle may indirectly consider past health by accounting for how far an individual is from achieving a complete, healthy life. I argue that proportional shortfall does not account for this lifetime perspective as it fails to incorporate the fair innings argument as originally claimed, undermining its purported justification.I go on to demonstrate that the case for ignoring past health is weak, and argue that past health is at least sometimes relevant for priority-setting decisions. Specifically, when an individual's past health has a direct impact on current or future health, and when one individual has enjoyed significantly more healthy life years than another.Finally, I demonstrate that by ignoring past illnesses, even those entirely unrelated to their current illness, proportional shortfall can lead to instances of double jeopardy, a highly problematic implication. These arguments give us reason to reject proportional shortfall. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018. All rights reserved.

While the ability to develop nanomaterials and incorporate them into products is advancing rapidly worldwide, understanding of the potential health safety effects of nanomaterials has proceeded at a much slower pace. Since 2008, Korea Food and Drug Administration (KFDA) started an investigation to prepare "Strategic Action Plan" to evaluate safety and nano risk management associated with foods, drugs, medical devices and cosmetics using nano-scale materials. Although there are some studies related to potential risk of nanomaterials, physical-chemical characterization of nanomaterials is not clear yet and these do not offer enough information due to their limitations. Their uncertainties make it impossible to determine whether nanomaterials are actually hazardous to human. According to the above mention, we have some problems to conduct the human exposure risk assessment currently. On the other hand, uncertainty about safety may lead to polarized public debate and to businesses unwillingness for further nanotechnology investigation. Therefore, the criteria and methods to assess possible adverse effects of nanomaterials have been vigorously taken into consideration by many international organizations: the World Health Organization, the Organization for Economic and Commercial Development and the European Commission. The object of this study was to develop risk assessment principles for safety management of future nanoproducts and also to identify areas of research to strengthen risk assessment for nanomaterials. The research roadmaps which were proposed in this study will be helpful to fill up the current gaps in knowledge relevant nano risk assessment.

The implications of the weak equivalence principles are investigated in detail for electromagnetic systems in a general framework. In particular, it is shown that the universality of free-fall trajectories (Galileo weak equivalence principle) does not imply the validity of the Einstein equivalence principle. However, the Galileo principle plus the universality of free-fall rotation states does imply the Einstein principle.

Ethnography: principles, practice and potential.

Science.gov (United States)

Draper, Jan

2015-05-06

Ethnography is a methodology that is gaining popularity in nursing and healthcare research. It is concerned with studying people in their cultural context and how their behaviour, either as individuals or as part of a group, is influenced by this cultural context. Ethnography is a form of social research and has much in common with other forms of qualitative enquiry. While classical ethnography was characteristically concerned with describing 'other' cultures, contemporary ethnography has focused on settings nearer to home. This article outlines some of the underlying principles and practice of ethnography, and its potential for nursing and healthcare practice.

On the Controllability Principles and the Construction of Uncontrollability

Friis, Ivar; Gevoll, Linn; Hansen, Allan

A key challenge when it comes to coping with the controllability principle is to understand why and how uncontrollability occurs. In this paper we draw on the Actor-Network Theory to provide more insight to why and how uncontrollability emerges in organizations. By means of an in-depth case study...... of a wide range of heterogeneous actors that connects in multiple ways and that in combination forms a complex network of relations which affect delivery time performance. Our study adds to research on the controllability principle. Whereas prior research has characterized uncontrollability as determined...... uncontrollability more specifically is about. Thus, our study adds to as well as elaborates on prior research. We illustrate how uncontrollability arise in the intersects of several heterogeneous elements such as the product information systems, quality management, incentive systems, outsourcing and customers.

Priority-setting in New Zealand: translating principles into practice.

Science.gov (United States)

Ashton, T; Cumming, J; Devlin, N

2000-07-01

In May 1998 the New Zealand Health Funding Authority released a discussion paper which proposed a principles-based approach to setting purchasing priorities that incorporates the economic methods of programme budgeting and marginal analysis, and cost-utility analysis. The principles upon which the process was to be based are effectiveness, cost, equity of health outcomes, Maori health and acceptability. This essay describes and critiques issues associated with translating the principles into practice, most particularly the proposed methods for evaluating the effectiveness and measuring the cost of services. It is argued that the proposals make an important contribution towards the development of a method for prioritizing services which challenges our thinking about those services and their goals, and which is systematic, explicit, and transparent. The shift towards 'thinking at the margin' and systematically reviewing the value for money of competing claims on resources is likely to improve the quality of decision-making compared with the status quo. This does not imply that prioritization can, or should, be undertaken by means of any simple formula. Any prioritization process should always be guided by informed judgement. The approach is more appropriate for some services than for others. Key methodological issues that need further consideration include the choice of instrument for measuring health gains, the identification of marginal services, how to combine qualitative and quantitative information, and how to ensure consistency across different levels of decision-making.

core of the basic design of the ICT in IBSE course. These principles can be considered as independent, validated educational products, which teacher educators can "buy into" and use for broader aims than only "ICT in IBSE" integration. Pedagogical principles establish the theoretical model underlying the course design, provide guidelines and structure to the (re)design, implementation, evaluation, and optimization process, and help to communicate the design-based research to others. The role of pedagogical principles in design-based research is indeed essential. Moreover, we incorporated a robustness test and a generalizability/transferability test as a further step in our design-based research and achieved successful outcomes with this step. Consequently, we strongly recommend the testing of the design product in routine implementation conditions and in considerably different contexts (e.g. different programmes or even countries) as part of design-based research.

Lean implementation strategies: how are the Toyota way principles addressed?

Directory of Open Access Journals (Sweden)

Coetzee, Rojanette

2016-11-01

Full Text Available Lean manufacturing is widely considered to be a proven organisational improvement philosophy, yet the success rate of lean implementation in industry remains relatively low. Neglect of the human aspect of lean manufacturing is often cited as the leading reason for this, despite the emphasis so clearly placed upon this aspect by the creators of the lean philosophy. This article reviews the extent to which the human dimensions of the lean philosophy, as described in the Toyota Way management principles, have been incorporated in lean implementation strategies. It is found that few of the principles feature prominently in these strategies. Notably absent are those linked to the ‘respect for people’ pillar , which forms half of the T oyota Way’s foundation. This conclusion indicates that the adoption of the lean philosophy runs contrary to the oft-repeated message from its creators that no tenet of the philosophy should be favoured at the expense of another. This may provide valuable insight into the reasons for the high implementation failure rate.

New Innovative Ethical Principles in Increasing Road Safety

Full Text Available Research Question (RQ: Future managers are faced daily with a variety of ethical dilemmas in traffic that need to be balanced by the interests of all participants. The question is whether a new innovative model of ethical principles could be developed that would increase road safety.Purpose: The a im is to raise the level of social responsibility and relationship of participants in traffic as well as warn all participants on the importance of safety. In addition, the purpose is to share suggestions to other researchers for further research studies in the area of increasing traffic safety.Method: We carried out a quantitative study (survey among first year post-graduate students studying at a higher education school focused on quality management in south-eastern Slovenia. The article presents five different ethical scenarios.Results: The participants have very similar views on judging individual ethical dilemmas. The desire to increase road safety, have led to new useful suggestions for further study of innovative new ethical principles in the field of safety, such as: no death victims annually, adequate road infrastructure, improved vehicle technology, video surveillance systems, and so on.Organization: Relevant authorities should promote models of ethical thinking and the introduction of codes of conduct at an early age. As such, the state, police, rescuers, fire departments, hospitals, and so on, would have fewer deaths due to serious traffic accidents.Society: By taking these results and further research suggestions into account, society would gain a new model that would be based on zero accidents annually.Originality: Research in the field of ethics and innovative ethical principles of traffic safety is limited. The article presents practical examples of ethical and moral decision-making that we encounter in daily traffic. But nothing much is done to make it better ("every day the same story".Limitations/Future Research: The research study

Ethical virtues in scientific research.

Science.gov (United States)

Resnik, David B

2012-01-01

Most approaches to promoting integrity in research are principle-based in that they portray ethical conduct as consisting of adherence to ethical rules, duties, or responsibilities. Bruce MacFarlane has recently criticized the principle-based approach to promoting integrity in research and offered a virtue-based alternative. MacFarlane argues that principle-based approaches do not provide adequate guidance for ethical decision-making and are not very useful in moral education. In this article, I examine and critique MacFarlane's defense of the virtue-based approach. I argue that virtue-based and principle-based approaches to ethics are complementary and that they both can help promote research integrity.

The Photo-Mosaic Assistant: Incorporating Historic Aerial Imagery into Modern Research Projects

Science.gov (United States)

Flathers, E.

2013-12-01

One challenge that researchers face as data organization and analysis shift into the digital realm is the incorporation of 'dirty' data from analog back-catalogs into current projects. Geospatial data collections in university libraries, government data repositories, and private industry contain historic data such as aerial photographs that may be stored as negatives, prints, and as scanned digital image files. A typical aerial imagery series is created by taking photos of the ground from an aircraft along a series of parallel flight lines. The raw photos can be assembled into a mosaic that represents the full geographic area of the collection, but each photo suffers from individual distortion according to the attitude and altitude of the collecting aircraft at the moment of acquisition, so there is a process of orthorectification needed in order to produce a planimetric composite image that can be used to accurately refer to locations on the ground. Historic aerial photo collections often need significant preparation for consumption by a GIS: they may need to be digitized, often lack any explicit spatial coordinates, and may not include information about flight line patterns. Many collections lack even such basic information as index numbers for the photos, so it may be unclear in what order the photos were acquired. When collections contain large areas of, for example, forest or agricultural land, any given photo may have few visual cues to assist in relating it to the other photos or to an area on the ground. The Photo-Mosaic Assistant (PMA) is a collection of tools designed to assist in the organization of historic aerial photo collections and the preparation of collections for orthorectification and use in modern research applications. The first tool is a light table application that allows a user to take advantage of visual cues within photos to organize and explore the collection, potentially building a rough image mosaic by hand. The second tool is a set of

Quantum maximum-entropy principle for closed quantum hydrodynamic transport within a Wigner function formalism

International Nuclear Information System (INIS)

Trovato, M.; Reggiani, L.

2011-01-01

By introducing a quantum entropy functional of the reduced density matrix, the principle of quantum maximum entropy is asserted as fundamental principle of quantum statistical mechanics. Accordingly, we develop a comprehensive theoretical formalism to construct rigorously a closed quantum hydrodynamic transport within a Wigner function approach. The theoretical formalism is formulated in both thermodynamic equilibrium and nonequilibrium conditions, and the quantum contributions are obtained by only assuming that the Lagrange multipliers can be expanded in powers of (ℎ/2π) 2 . In particular, by using an arbitrary number of moments, we prove that (1) on a macroscopic scale all nonlocal effects, compatible with the uncertainty principle, are imputable to high-order spatial derivatives, both of the numerical density n and of the effective temperature T; (2) the results available from the literature in the framework of both a quantum Boltzmann gas and a degenerate quantum Fermi gas are recovered as a particular case; (3) the statistics for the quantum Fermi and Bose gases at different levels of degeneracy are explicitly incorporated; (4) a set of relevant applications admitting exact analytical equations are explicitly given and discussed; (5) the quantum maximum entropy principle keeps full validity in the classical limit, when (ℎ/2π)→0.

Quigley, Dianne

2015-02-01

A collaborative team of environmental sociologists, community psychologists, religious studies scholars, environmental studies/science researchers and engineers has been working together to design and implement new training in research ethics, culture and community-based approaches for place-based communities and cultural groups. The training is designed for short and semester-long graduate courses at several universities in the northeastern US. The team received a 3 year grant from the US National Science Foundation's Ethics Education in Science and Engineering in 2010. This manuscript details the curriculum topics developed that incorporate ethical principles, particularly for group protections/benefits within the field practices of environmental/engineering researchers.

DETERMINATION OF QMS PRINCIPLE COEFFICIENTS OF SIGNIFICANCE IN ACHIEVING BUSINESS EXCELLENCE

2008-03-01

Full Text Available This paper has been developed as a tendency of researchers in the Center for quality-Faculty of mechanical engineering in Podgorica to establish a model for improvement of business processes performances based on quality management system through comparison with top organizational performances characterized by criteria i.e. particularities of the business excellence model. Correlation of principles of the quality management system with QMS principles has been established to that effect. Weight coefficients have been also determined for each principle individually. Thereby key principles were identified, namely priorities in terms of achieving business excellence i.e. areas (principles were given priorities, that is to say principles that play the biggest part in achieving business excellence. In that way, pre conditions were made to define preventive measures of a certain intensity depending on the weight coefficients, with a goal to improve performances of a certified and process-modulated quality management system in direction of achieving top organizational performances.

2013-01-01

Life course perspective, social determinants of health, and health equity have been combined into one comprehensive model, the life course model (LCM), for strategic planning by US Health Resources and Services Administration's Maternal and Child Health Bureau. The purpose of this project was to describe a faculty development process; identify strategies for incorporation of the LCM into nutrition leadership education and training at the graduate and professional levels; and suggest broader implications for training, research, and practice. Nineteen representatives from 6 MCHB-funded nutrition leadership education and training programs and 10 federal partners participated in a one-day session that began with an overview of the models and concluded with guided small group discussions on how to incorporate them into maternal and child health (MCH) leadership training using obesity as an example. Written notes from group discussions were compiled and coded emergently. Content analysis determined the most salient themes about incorporating the models into training. Four major LCM-related themes emerged, three of which were about training: (1) incorporation by training grants through LCM-framed coursework and experiences for trainees, and similarly framed continuing education and skills development for professionals; (2) incorporation through collaboration with other training programs and state and community partners, and through advocacy; and (3) incorporation by others at the federal and local levels through policy, political, and prevention efforts. The fourth theme focused on anticipated challenges of incorporating the model in training. Multiple methods for incorporating the LCM into MCH training and practice are warranted. Challenges to incorporating include the need for research and related policy development.

Using Green Chemistry and Engineering Principles to Design ...

Science.gov (United States)

The concepts of green chemistry and engineering (GC&E) have been promoted as an effective qualitative framework for developing more sustainable chemical syntheses, processes, and material management techniques. This has been demonstrated by many theoretical and practical cases. In addition, there are several approaches and frameworks focused on demonstrating that improvements were achieved through GC&E technologies. However, the application of these principles is not always straightforward. We propose using systematic frameworks and tools that help practitioners when deciding which principles can be applied, the levels of implementation, prospective of obtaining simultaneous improvements in all sustainability aspects, and ways to deal with multiobjective problems. Therefore, this contribution aims to provide a systematic combination of three different and complementary design tools for assisting designers in evaluating, developing, and improving chemical manufacturing and material management systems under GC&E perspectives. The WAR Algorithm, GREENSCOPE, and SustainPro were employed for this synergistic approach of incorporating sustainability at early stages of process development. In this demonstration, simulated ammonia production is used as a case study to illustrate this advancement. Results show how to identify process design areas for improvements, key factors, multi-criteria decision-making solutions, and optimal tradeoffs. Finally, conclusions were pre

Mach's holographic principle

International Nuclear Information System (INIS)

Khoury, Justin; Parikh, Maulik

2009-01-01

Mach's principle is the proposition that inertial frames are determined by matter. We put forth and implement a precise correspondence between matter and geometry that realizes Mach's principle. Einstein's equations are not modified and no selection principle is applied to their solutions; Mach's principle is realized wholly within Einstein's general theory of relativity. The key insight is the observation that, in addition to bulk matter, one can also add boundary matter. Given a space-time, and thus the inertial frames, we can read off both boundary and bulk stress tensors, thereby relating matter and geometry. We consider some global conditions that are necessary for the space-time to be reconstructible, in principle, from bulk and boundary matter. Our framework is similar to that of the black hole membrane paradigm and, in asymptotically anti-de Sitter space-times, is consistent with holographic duality.

2017-01-01

This book reflects the latest advances in nonlinear optics. Besides the simple, strict mathematical deduction, it also discusses the experimental verification and possible future applications, such as the all-optical switches. It consistently uses the practical unit system throughout. It employs simple physical images, such as "light waves" and "photons" to systematically explain the main principles of nonlinear optical effects. It uses the first-order nonlinear wave equation in frequency domain under the condition of “slowly varying amplitude approximation" and the classical model of the interaction between the light and electric dipole. At the same time, it also uses the rate equations based on the energy-level transition of particle systems excited by photons and the energy and momentum conservation principles to explain the nonlinear optical phenomenon. The book is intended for researchers, engineers and graduate students in the field of the optics, optoelectronics, fiber communication, information tech...

Exploring the Principles and Practices of One Teacher of L2 Speaking: The Importance of Reflecting on Practice

Directory of Open Access Journals (Sweden)

Thomas S. C. Farrell

2018-01-01

Full Text Available Teacher principles encompass a teacher’s stated assumptions, beliefs, and conceptions about acquiring and teaching a second language (L2. Due to the complex and diversified nature of how principles take form, an individual teacher’s principles will influence their judgements, perceptions and instructional decisions, thus affecting the outcome of classroom practices. Exploring teacher principles and their impact on classroom practices and vice versa is an invaluable and necessary component to research in L2 teaching and learning since it plays an influential role in instructional outcomes.This paper explores the nature of the principles/practice relationship through an investigative case study with an ESL teacher of L2 speaking. Additionally, the results of research on principles and practices related to L2 teaching when conducted by academics rarely gets back to teachers in the front lines. Thus the researchers shared their findings with the teacher who as a result of reflecting on the analysis came up with a set of principles she says guides her teaching of L2 speaking.

Problems encountered in embodying the principles of ICRP-26 and the revised IAEA safety standards into UK national legislation

International Nuclear Information System (INIS)

Beaver, P.F.

1979-01-01

This paper describes the United Kingdom procedures and format for safety legislation and goes on to show how the necessary legislation for radiological protection will fit into the general framework. The United Kingdom, as a member of the European Community and EURATOM, is bound to implement the Euratom Directive on radiological protection within the next few years. The latest draft of the Directive takes account of the recommendations of ICRP-26 and further, a recent draft of the revised IAEA Basic Safety Standards is a composite of both the Directive and ICRP-26. Thus, the effect of embodying the principles of the Directive is to embody the principles of ICRP-26 and the Basic Safety Standards. Some of the problems which have been met are described and in particular there is discussion of the problems arising from the incorporation of the three ICRP-26 facets of dose control, namely justification, optimization and limitation, into a legislative package. The UK system of evolving safety legislation now requires considerable participation by all the parties affected (or by their representatives). This paper indicates that the involvement of persons affected, coupled with a legislative package which consists of a hierarchy of (a) regulations; (b) codes of practice; and (c) guidance notes, will result in the fundamental principles of ICRP-26 being incorporated into UK legislation in a totally acceptable way.

The use of electronic technology allows faculty to improve their course offerings. Four graduate courses in nursing administration were contemporized to incorporate fundamental computer-based skills that would be expected of graduates in the work setting. Principles of adult learning offered a philosophical foundation that guided course development and revision. Course delivery strategies included computer-assisted instructional modules, e-mail interactive discussion groups, and use of the electronic classroom. Classroom seminar discussions and two-way interactive video conferencing focused on group resolution of problems derived from employment settings and assigned readings. Using these electronic technologies, a variety of courses can be revised to accommodate the learners' needs.

Oxygen adsorption and incorporation at irradiated GaN(0001) and GaN(0001¯) surfaces: First-principles density-functional calculations

Science.gov (United States)

Sun, Qiang; Selloni, Annabella; Myers, T. H.; Doolittle, W. Alan

2006-11-01

Density functional theory calculations of oxygen adsorption and incorporation at the polar GaN(0001) and GaN(0001¯) surfaces have been carried out to explain the experimentally observed reduced oxygen concentration in GaN samples grown by molecular beam epitaxy in the presence of high energy (˜10keV) electron beam irradiation [Myers , J. Vac. Sci. Technol. B 18, 2295 (2000)]. Using a model in which the effect of the irradiation is to excite electrons from the valence to the conduction band, we find that both the energy cost of incorporating oxygen impurities in deeper layers and the oxygen adatom diffusion barriers are significantly reduced in the presence of the excitation. The latter effect leads to a higher probability for two O adatoms to recombine and desorb, and thus to a reduced oxygen concentration in the irradiated samples, consistent with experimental observations.

2013-12-01

Mixed methods research offers powerful tools for investigating complex processes and systems in health and health care. This article describes integration principles and practices at three levels in mixed methods research and provides illustrative examples. Integration at the study design level occurs through three basic mixed method designs-exploratory sequential, explanatory sequential, and convergent-and through four advanced frameworks-multistage, intervention, case study, and participatory. Integration at the methods level occurs through four approaches. In connecting, one database links to the other through sampling. With building, one database informs the data collection approach of the other. When merging, the two databases are brought together for analysis. With embedding, data collection and analysis link at multiple points. Integration at the interpretation and reporting level occurs through narrative, data transformation, and joint display. The fit of integration describes the extent the qualitative and quantitative findings cohere. Understanding these principles and practices of integration can help health services researchers leverage the strengths of mixed methods. © Health Research and Educational Trust.

Russian Imperial Principles and Technologies of the Management ofEthno-Confessional Diversity and of the Integration of Traditional Socio-Cultural Systems

Directory of Open Access Journals (Sweden)

Igor I. Verniaev

2016-10-01

Full Text Available This article discusses the new monograph by Boris Mironov, “The Russian Empire: From Tradition to Modernity,” which is devoted to the social history of Russia in the imperial period. One of its main characteristics is its fundamental interdisciplinarity and the use of various research methods and strategies. Mironov synthesizes the approaches of social, economic, political and visual history, social anthropology, historical demography, sociology, political science and psychology. I.I. Verniaev, an ethnographer by profession, views this book through the eyes of an ethnographer and analyzes it from the perspective of social anthropology. In his opinion, Mironov succeeded in deeply analyzing the principles and technologies of management of ethnic and confessional diversity and the transformation of traditional socio-cultural institutions. The article discusses how Mironov identifies and analyzes such imperial principles and technologies of management of ethno-confessional diversity, modernization, and integration of socio-cultural systems as maintaining the status quo, the relative autonomy of ethnic groups in the early stages of incorporation of the national borderlands, ethnic and religious tolerance, the use of intermediate symbiotic (neo-traditional, in terms of ethnography institutions, confessionalization, the predominance of social rather than ethnic assimilation, legitimation and the ennoblement of national elites, their inclusion in the system of governance of the empire, the extension and adaptation of the estate system to include new groups of the population from the national borderlands, the confessionalization of religions, and the empowerment of the clergy through rights and responsibilities in the administrative system. These processes are interpreted in terms of models of traditional societies and cultures developed in modern ethnography, and the manner of their modernization and incorporation into modern society.

International network on incorporation of ageing effects into PSA

Kirchsteiger, C.; Patrik, M.

2006-01-01

This paper describes the background and status of a new International Network on ''Incorporating Ageing Effects into Probabilistic Safety Assessment''. The Joint Research Centre (JRC) of the European Commission organized in September 2004 the kickoff meeting of this Network at JRC's Institute for Energy in Petten, Netherlands, with the aims to open the APSA Network, to start discussion of ageing issues in relation to incorporating ageing effects into PSA tools and to come to consensus on objectives and work packages of the Network, taking into account the specific expectations of potential Network partners. The presentations and discussions at the meeting confirmed the main conclusion from the previously organized PSAM 7 pre-conference workshop on ''Incorporating PSA into Ageing Management'', Budapest, June 2004, namely that incorporating ageing effects into PSA seems to be more and more a hot topic particularly for risk assessment and ageing management of nuclear power plants operating at advanced age (more than 25-30 years) and for the purpose of plant life extension. However, it also appeared that, especially regarding the situation in Europe, at present there are several on-going feasibility or full studies in this area, but not yet a completed Ageing PSA leading to applications. The project's working method is a NETWORK of operators, industry, research, academia and consultants with an active interest in the area (physical networking via a series of workshops and virtual networking via the Internet). The resulting knowledge should help PSA developers and users to incorporate the effects of equipment ageing into current PSA tools and models, to identify and/or develop most effective corresponding methods, to focus on dominant ageing contributors and components and to promote the use of PSA for ageing management of Nuclear Power Plants.

Middleton, J

1983-12-01

Considerable experience and research has been accumulated in the last 20 years on the ways in which information/education/communication (IEC) programs can be effectively designed, implemented, and evaluated. Possibly more effort has focused on population and family planning IEC than on any other sectoral program of development communication. Several principles have emerged which, taken together, define the state of the art in the field. These principles provide a framework of experience which can guide the development of comprehensive IEC programs. They include: policy and resource assessment; audience analysis; strategy design; message research and pretesting; participation and feedback; management; evaluation; and collaboration. The nature of the national policy base for population and family planning programs will determine the goals and approaches of the IEC program. Strong policies of limitation on popultion growth lead to equally strong and pervasive IEC efforts designed to directly affect contraceptive behavior. Assessment of existing policy is an essential aspect of the design of an effective IEC program. Policies establish the rationale and boundaries for action. Population and family planning programs are concerned with some of the most intimate human behavior. Consequently, structured and sensitive audience analysis has become an integral part of the design of IEC programs. The design of communication strategy requires clearly stated objectives. Principles of human learning are used to structure information appropriately. Message research and pretesting have become integral components of the strategy design process. Small scale research on specific objectives is necessary to establish the basis for message design. Audience participation and feedback in remaining phases of program development and implementation are important. The management of an IEC program requires a specific combination of planning, flexibility, and creativity. Evaluation of program

Nature as capital: Advancing and incorporating ecosystem services in United States federal policies and programs.

Science.gov (United States)

Schaefer, Mark; Goldman, Erica; Bartuska, Ann M; Sutton-Grier, Ariana; Lubchenco, Jane

2015-06-16

The concept of nature as capital is gaining visibility in policies and practices in both the public and private sectors. This change is due to an improved ability to assess and value ecosystem services, as well as to a growing recognition of the potential of an ecosystem services approach to make tradeoffs in decision making more transparent, inform efficient use of resources, enhance resilience and sustainability, and avoid unintended negative consequences of policy actions. Globally, governments, financial institutions, and corporations have begun to incorporate natural capital accounting in their policies and practices. In the United States, universities, nongovernmental organizations, and federal agencies are actively collaborating to develop and apply ecosystem services concepts to further national environmental and economic objectives. Numerous federal agencies have begun incorporating these concepts into land use planning, water resources management, and preparations for, and responses to, climate change. Going forward, well-defined policy direction will be necessary to institutionalize ecosystem services approaches in federal agencies, as well as to guide intersector and interdisciplinary collaborative research and development efforts. In addition, a new generation of decision support tools are needed to further the practical application of ecosystem services principles in policymaking and commercial activities. Improved performance metrics are needed, as are mechanisms to monitor the status of ecosystem services and assess the environmental and economic impacts of policies and programs. A greater national and international financial commitment to advancing ecosystem services and natural capital accounting would likely have broad, long-term economic and environmental benefits.

In 1998, the North American Primary Care Research Group (NAPCRG) adopted a groundbreaking Policy Statement endorsing responsible participatory research (PR) with communities. Since that time, PR gained prominence in primary care research. To reconsider the original 1998 Policy Statement in light of increased uptake of PR, and suggest future directions and applications for PR in primary care. This work contributed to an updated Policy Statement endorsed by NAPCRG in 2015. 32 university and 30 community NAPCRG-affiliated research partners, convened a workshop to document lessons learned about implementing processes and principles of PR. This document emerged from that session and reflection and discussion regarding the original Policy Statement, the emerging PR literature, and our own experiences. The foundational principles articulated in the 1998 Policy Statement remain relevant to the current PR environment. Lessons learned since its publication include that the maturation of partnerships is facilitated by participatory processes that support increased community responsibility for research projects, and benefits generated through PR extend beyond research outcomes. Future directions that will move forward the field of PR in primary care include: (i) improve assessment of PR processes to better delineate the links between how PR teams work together and diverse PR outcomes, (ii) increase the number of models incorporating PR into translational research from project inception to dissemination, and (iii) increase application of PR approaches that support patient engagement in clinical settings to patient-provider relationship and practice change research. PR has markedly altered the manner in which primary care research is undertaken in partnership with communities and its principles and philosophies continue to offer means to assure that research results and processes improve the health of all communities. © The Author 2016.

Principles for Helpful Sequence and Deduction of Knowledge Organization Systems - An Exploratory Study

Directory of Open Access Journals (Sweden)

Asundi, A.Y.

2013-06-01

Full Text Available Dr. Ranganathan's "Principles for Helpful Sequence" among the set of normative principles play an exclusive role in the arrangement of subject isolates. Each subject in the universe of subjects is regulated by a guiding principle of its own which analogously determines the sequence of Arrays in ordering the subject surrogates or isolates. For example, the "Principle of Later-in-Evolution" is applied for sequencing isolates of Animal and Plant Species; this concept can be applied to one of the tools of KOS viz. Taxonomies. The application of Principles for Helpful Sequence is summarily presented and in the process the paper highlights the inherent elements of knowledge organization in each one of these principles in a manner that might map the future course of research in this area with the potentiality to bring about a relation between principles for helpful sequence and KOS.

Legitimacy of the Restorative Justice Principle in the Context of Criminal Law Enforcement

Directory of Open Access Journals (Sweden)

- Sukardi

2014-10-01

Full Text Available This research reviews the essence of the restorative justice principle as an approach in the settlement of criminal cases, and it aims to provide an overview of the construction of the restorative justice principle in criminal law enforcement. The outcomes of the research indicate that the restorative justice principle has been subject to frequent study in its understanding as an alternative criminal case settlement method, by way of positioning outside the criminal judiciary system. As it turns out in practice, however, it has certain weaknesses, particularly in view of the accountability and legitimacy aspects of its establishment. Therefore, there is a need for a scientific investigation process for the purpose of determining the status of parties involved in a case, as well as for positioning the case concerned. Based on such view, the restorative justice principle appears to be the ideal approach to be applied in the criminal judiciary system.

A Variation on Uncertainty Principle and Logarithmic Uncertainty Principle for Continuous Quaternion Wavelet Transforms

Directory of Open Access Journals (Sweden)

Mawardi Bahri

2017-01-01

Full Text Available The continuous quaternion wavelet transform (CQWT is a generalization of the classical continuous wavelet transform within the context of quaternion algebra. First of all, we show that the directional quaternion Fourier transform (QFT uncertainty principle can be obtained using the component-wise QFT uncertainty principle. Based on this method, the directional QFT uncertainty principle using representation of polar coordinate form is easily derived. We derive a variation on uncertainty principle related to the QFT. We state that the CQWT of a quaternion function can be written in terms of the QFT and obtain a variation on uncertainty principle related to the CQWT. Finally, we apply the extended uncertainty principles and properties of the CQWT to establish logarithmic uncertainty principles related to generalized transform.

Fair Information Principles of Brazilian Companies online privacy policies

Directory of Open Access Journals (Sweden)

Patricia Zeni Marchiori

2016-05-01

Full Text Available This research aims to present the Fair Information Principles in the privacy policies of the websites of major Brazilian companies (according to the 2014 Forbes Magazine list. The check and analysis were supported by a checklist compiled from documents issued by the Federal Trade Commission and the Organization for Economic Co-operation and development. The study selected fourteen companies from a universe of twenty-five, considering the immediacy criterion of access to the privacy policy on their websites. The security (safeguards principle is the most widespread foundation at the privacy policies of the companies selected (existing in eight of the fourteen analyzed policies; and the principle of responsibility receives less adhesion due to the fact that it is not covered in any of the examined online privacy policies. The Sabesp Company presents the most complete privacy policy, considering the compliance with the Fair Information Principles when compared to the others perused, while WEG does not present any of the principles identified in the documental survey. As for e-commerce, the number of companies that assume some of the Principles is further reduced. For the selected universe the adherence to the Fair information Principles is still incipient, althought its use is not mandatory. An open discussion of the proposed Brazilian law about personal data protection should play an important role in creating further guidance on the subject. Additional studies in this subject should involve the perception of users, as well as a cutout of companies which target e-commerce, considering that an effective alignment with these principles and other guidelines are required in order to protect the user’s privacy and personal data in the web environment.

The genetic difference principle.

Science.gov (United States)

Farrelly, Colin

2004-01-01

In the newly emerging debates about genetics and justice three distinct principles have begun to emerge concerning what the distributive aim of genetic interventions should be. These principles are: genetic equality, a genetic decent minimum, and the genetic difference principle. In this paper, I examine the rationale of each of these principles and argue that genetic equality and a genetic decent minimum are ill-equipped to tackle what I call the currency problem and the problem of weight. The genetic difference principle is the most promising of the three principles and I develop this principle so that it takes seriously the concerns of just health care and distributive justice in general. Given the strains on public funds for other important social programmes, the costs of pursuing genetic interventions and the nature of genetic interventions, I conclude that a more lax interpretation of the genetic difference principle is appropriate. This interpretation stipulates that genetic inequalities should be arranged so that they are to the greatest reasonable benefit of the least advantaged. Such a proposal is consistent with prioritarianism and provides some practical guidance for non-ideal societies--that is, societies that do not have the endless amount of resources needed to satisfy every requirement of justice.

Feminist intersectionality: bringing social justice to health disparities research.

Science.gov (United States)

Rogers, Jamie; Kelly, Ursula A

2011-05-01

The principles of autonomy, beneficence, non-maleficence, and justice are well established ethical principles in health research. Of these principles, justice has received less attention by health researchers. The purpose of this article is to broaden the discussion of health research ethics, particularly the ethical principle of justice, to include societal considerations--who and what are studied and why?--and to critique current applications of ethical principles within this broader view. We will use a feminist intersectional approach in the context of health disparities research to firmly establish inseparable links between health research ethics, social action, and social justice. The aim is to provide an ethical approach to health disparities research that simultaneously describes and seeks to eliminate health disparities. © The Author(s) 2011

Variational principles for collective motion: Relation between invariance principle of the Schroedinger equation and the trace variational principle

International Nuclear Information System (INIS)

Klein, A.; Tanabe, K.

1984-01-01

The invariance principle of the Schroedinger equation provides a basis for theories of collective motion with the help of the time-dependent variational principle. It is formulated here with maximum generality, requiring only the motion of intrinsic state in the collective space. Special cases arise when the trial vector is a generalized coherent state and when it is a uniform superposition of collective eigenstates. The latter example yields variational principles uncovered previously only within the framework of the equations of motion method. (orig.)

Subsurface Conditions Controlling Uranium Incorporation in Iron Oxides: A Redox Stable Sink

International Nuclear Information System (INIS)

Fendorf, Scott

2016-01-01

Toxic metals and radionuclides throughout the U.S. Department of Energy Complex pose a serious threat to ecosystems and to human health. Of particular concern is the redox-sensitive radionuclide uranium, which is classified as a priority pollutant in soils and groundwaters at most DOE sites owing to its large inventory, its health risks, and its mobility with respect to primary waste sources. The goal of this research was to contribute to the long-term mission of the Subsurface Biogeochemistry Program by determining reactions of uranium with iron (hydr)oxides that lead to long-term stabilization of this pervasive contaminant. The research objectives of this project were thus to (1) identify the (bio)geochemical conditions, including those of the solid-phase, promoting uranium incorporation in Fe (hydr)oxides, (2) determine the magnitude of uranium incorporation under a variety of relevant subsurface conditions in order to quantify the importance of this pathway when in competition with reduction or adsorption; (3) identify the mechanism(s) of U(VI/V) incorporation in Fe (hydr)oxides; and (4) determine the stability of these phases under different biogeochemical (inclusive of redox) conditions. Our research demonstrates that redox transformations are capable of achieving U incorporation into goethite at ambient temperatures, and that this transformation occurs within days at U and Fe(II) concentrations that are common in subsurface geochemical environments with natural ferrihydrites - inclusive of those with natural impurities. Increasing Fe(II) or U concentration, or initial pH, made U(VI) reduction to U(IV) a more competitive sequestration pathway in this system, presumably by increasing the relative rate of U reduction. Uranium concentrations commonly found in contaminated subsurface environments are often on the order of 1-10 μM, and groundwater Fe(II) concentrations can reach exceed 1 mM in reduced zones of the subsurface.

A Parent's Journey: Incorporating Principles of Palliative Care into Practice for Children with Chronic Neurologic Diseases.

Science.gov (United States)

Brown, Allyson; Clark, Jonna D

2015-09-01

Rather than in conflict or in competition with the curative model of care, pediatric palliative care is a complementary and transdisciplinary approach used to optimize medical care for children with complex medical conditions. It provides care to the whole child, including physical, mental, and spiritual dimensions, in addition to support for the family. Through the voice of a parent, the following case-based discussion demonstrates how the fundamentals of palliative care medicine, when instituted early in the course of disease, can assist parents and families with shared medical decision making, ultimately improving the quality of life for children with life-limiting illnesses. Pediatric neurologists, as subspecialists who provide medical care for children with chronic and complex conditions, should consider invoking the principles of palliative care early in the course of a disease process, either through applying general facets or, if available, through consultation with a specialty palliative care service.

First-Principles Lattice Dynamics Method for Strongly Anharmonic Crystals

Science.gov (United States)

Tadano, Terumasa; Tsuneyuki, Shinji

2018-04-01

We review our recent development of a first-principles lattice dynamics method that can treat anharmonic effects nonperturbatively. The method is based on the self-consistent phonon theory, and temperature-dependent phonon frequencies can be calculated efficiently by incorporating recent numerical techniques to estimate anharmonic force constants. The validity of our approach is demonstrated through applications to cubic strontium titanate, where overall good agreement with experimental data is obtained for phonon frequencies and lattice thermal conductivity. We also show the feasibility of highly accurate calculations based on a hybrid exchange-correlation functional within the present framework. Our method provides a new way of studying lattice dynamics in severely anharmonic materials where the standard harmonic approximation and the perturbative approach break down.

2015-01-01

This book presents a self-contained treatment of the principles and major applications of digital hologram recording and numerical reconstruction (Digital Holography). This second edition has been significantly revised and enlarged. The authors have extended the chapter on Digital Holographic Microscopy to incorporate new sections on particle sizing, particle image velocimetry and underwater holography. A new chapter now deals comprehensively and extensively with computational wave field sensing. These techniques represent a fascinating alternative to standard interferometry and Digital Holography. They enable wave field sensing without the requirement of a particular reference wave, thus allowing the use of low brilliance light sources and even liquid-crystal displays (LCD) for interferometric applications.              

Universal Principles of Media Ethics: South African and German Perspectives

Directory of Open Access Journals (Sweden)

Lea-Sophie Borgmann

2012-11-01

Full Text Available The increasingly globalised nature of media and journalism has led to a review of ethical standards, mainly to find universal ethical values which are applicable in a world with countless different cultures. This article attempts to address this field of research in comparing South African and German approaches to the topic of media ethics. Firstly, it outlines theories of universal and specific cultural ethical principles in journalism. Secondly, it shows how the conception of universal ethical principles, so called protonorms, is interpreted differently in the two cultures and how specific cultural values of media ethics are rated among the two cultural frameworks of Germany and South Africa. An online survey conducted among German and South African journalism students found significant differences in the ranking of media ethics principles as well as similarities and differences in the interpretations of protonorms. The results support existing normative theories of universal media ethics, such as the theory of protonorms, in contributing explorative empirical data to this field of mainly theoretical research.

Since several years risk-based monitoring is the new "magic bullet" for improvement in clinical research. Lots of authors in clinical research ranging from industry and academia to authorities are keen on demonstrating better monitoring-efficiency by reducing monitoring visits, monitoring time on site, monitoring costs and so on, always arguing with the use of risk-based monitoring principles. Mostly forgotten is the fact, that the use of risk-based monitoring is only adequate if all mandatory prerequisites at site and for the monitor and the sponsor are fulfilled.Based on the relevant chapter in ICH GCP (International Conference on Harmonisation of technical requirements for registration of pharmaceuticals for human use - Good Clinical Practice) this publication takes a holistic approach by identifying and describing the requirements for future monitoring and the use of risk-based monitoring. As the authors are operational managers as well as QA (Quality Assurance) experts, both aspects are represented to come up with efficient and qualitative ways of future monitoring according to ICH GCP.

The active involvement of people with intellectual disabilities in research, or inclusive research, is relatively common. However, inclusive health research is less common, even though it is expected to lead to appropriate healthcare and increased quality of life. Inclusive health research can build upon lessons learned from inclusive research. A total of 17 experts on inclusive (health) research without intellectual disabilities and 40 experts with intellectual disabilities collaborated in this consensus statement. The consensus statement was developed in three consecutive rounds: (1) an initial feedback round; (2) a roundtable discussion at the 2016 International Association for the Scientific Study of Intellectual and Developmental Disabilities World Congress; and (3) a final feedback round. This consensus statement provides researchers with guidelines, agreed upon by experts in the field, regarding attributes, potential outcomes, reporting and publishing, and future research directions, for designing and conducting inclusive health research. Consensus was reached on how to design and conduct inclusive health research. However, this statement should be continuously adapted to incorporate recent knowledge. The focus of this consensus statement is largely on inclusive health research, but the principles can also be applied to other areas. © 2018 MENCAP and International Association of the Scientific Study of Intellectual and Developmental Disabilities and John Wiley & Sons Ltd.

2018-06-07

The interpretive paradigm and hermeneutic phenomenological design are the most popular methods used in international cross-cultural research in healthcare, nurse education and nursing practice. Their inherent appeal is that they help researchers to explore experiences. The ethnographic principle of cultural interpretation can also be used to provide meaning, clarity and insight. To examine the use of hermeneutic phenomenology and the ethnographic principle of cultural interpretation in a research study conducted with Malaysian nurses on part-time, transnational, post-registration, top-up nursing degree programmes provided by one Australian and two UK universities. To enable the researcher to undertake international cross-cultural research and illuminate Malaysian nurses' views for the reader, cultural aspects need to be considered, as they will influence the information participants provide. Useful strategies that western researchers can adopt to co-create research texts with interviewees are outlined. The paradigm and research designs used in the study revealed the views and experiences of Malaysian nurses. Hermeneutic phenomenology enabled the exploration of participants' experiences, and the ethnographic principle of cultural interpretation enabled the researcher's reflexivity to provide emic and etic views for the reader. This paper adds to the discussion of the paradigms and research designs used for international, cross-cultural research in Asia. It identifies the influence participants' cultural values have on their confidence and level of disclosure with western researchers. ©2018 RCN Publishing Company Ltd. All rights reserved.

Cognitive Ability, Principled Reasoning and Political Tolerance

Hebbelstrup Rye Rasmussen, Stig; Nørgaard, Asbjørn Sonne

Individuals are not equally politically tolerant. To explain why, individual differences in emotions and threat have received much scholarly attention in recent years. However, extant research also shows that psychological dispositions, habitual cognitive styles, ideological orientation...... and ‘principled reasoning’ influence political tolerance judgments. The extent to which cognitive ability plays a role has not been entertained even if the capacity to think abstractly, comprehend complex ideas and apply abstract ideas to concrete situations is inherent to both principled tolerance judgment...... and cognitive ability. Cognitive ability, we argue and show, adds to the etiology of political tolerance. In Danish and American samples cognitive ability strongly predicts political tolerance after taking habitual cognitive styles (as measured by personality traits), education, social ideology, and feelings...

THE EQUALITY PRINCIPLE REQUIREMENTS

Directory of Open Access Journals (Sweden)

CLAUDIA ANDRIŢOI

2013-05-01

Full Text Available The problem premises and the objectives followed: the idea of inserting the equality principle between the freedom and the justice principles is manifested in positive law in two stages, as a general idea of all judicial norms and as requirement of the owner of a subjective right of the applicants of an objective law. Equality in face of the law and of public authorities can not involve the idea of standardization, of uniformity, of enlisting of all citizens under the mark of the same judicial regime, regardless of their natural or socio-professional situation. Through the Beijing Platform and the position documents of the European Commission we have defined the integrative approach of equality as representing an active and visible integration of the gender perspective in all sectors and at all levels. The research methods used are: the conceptualist method, the logical method and the intuitive method necessary as means of reasoning in order to argue our demonstration. We have to underline the fact that the system analysis of the research methods of the judicial phenomenon doesn’t agree with “value ranking”, because one value cannot be generalized in rapport to another. At the same time, we must fight against a methodological extremism. The final purpose of this study is represented by the reaching of the perfecting/excellence stage by all individuals through the promotion of equality and freedom. This supposes the fact that the existence of a non-discrimination favourable frame (fairness represents a means and a condition of self-determination, and the state of perfection/excellency is a result of this self-determination, the condition necessary for the obtaining of this nondiscrimination frame for all of us and in conditions of freedom for all individuals, represents the same condition that promotes the state of perfection/excellency. In conclusion we may state the fact that the equality principle represents a true catalyst of the

Ethical issues in research on children

Đurić Slađana

2012-01-01

Full Text Available Ethical issues that appear in researching children are the subject matter of relatively rich scientific literature, as well as a multitude of national and professional ethical codices. The broad thematization of ethical principles is indeed instigated by the rise of awareness of the seriousness of this problem, as well as by growing fears of potential abuse of children in contemporary research projects. General assertion that children are a vulnerable category of subjects that require special attention and protection from misuse in research projects prevails in literature. The main objective of this paper is to present general ethical issues that various areas of expertise researchers face when children and youth are the subjects of their studies. The principle of voluntary participation, the principle of balanced researcher - respondent relationship, and the principles of privacy, confidentiality and anonymity in studies of children are particularly presented.

Greatest Happiness Principle in a Complex System Approach

Directory of Open Access Journals (Sweden)

Katalin Martinás

2012-06-01

Full Text Available The principle of greatest happiness was the basis of ethics in Plato’s and Aristotle’s work, it served as the basis of utility principle in economics, and the happiness research has become a hot topic in social sciences in Western countries in particular in economics recently. Nevertheless there is a considerable scientific pessimism over whether it is even possible to affect sustainable increases in happiness.In this paper we outline an economic theory of decision based on the greatest happiness principle (GHP. Modern equilibrium economics is a simple system simplification of the GHP, the complex approach outlines a non-equilibrium economic theory. The comparison of the approaches reveals the fact that the part of the results – laws of modern economics – follow from the simplifications and they are against the economic nature. The most important consequence is that within the free market economy one cannot be sure that the path found by it leads to a beneficial economic system.

Hypertension criterion for stroke prevention--to strengthen the principle of individualization in guidelines.

Chen, Yicong; Chen, Xinran; Dang, Ge; Zhao, Yuhui; Ouyang, Fubing; Su, Zhenpei; Zeng, Jinsheng

2015-03-01

The diagnosis of hypertension, as recommended by most guidelines, is determined by systolic blood pressure ≥140 mm Hg and/or diastolic blood pressure ≥90 mm Hg. A threshold-based definition of hypertension, however, ignores sex and age, pathophysiology, and disparities in patient-specific conditions. Moreover, the harmful effects of hypertension-induced target organ damage cannot be ignored. Although the principle of individualization for hypertension management is recommended, especially for stroke prevention, how to practice it in a clinical setting has not been clearly elaborated. Therefore, we put forward a proposal for individualized hypertension management incorporating target organ damage, the main harmful effect of hypertension. We propose that hypertension should be diagnosed when an individual's blood pressure exceeds some difference from their own baseline in young adulthood, accompanied by any hypertension-induced target organ damage, confirmed by various detection methods. Application of this proposal to stroke prevention will hopefully strengthen the principle of individualized hypertension management. ©2015 Wiley Periodicals, Inc.

Incorporating Lean Construction agent into the Building Standards Act: the Spanish case study

Directory of Open Access Journals (Sweden)

Brioso Xavier

2016-12-01

Full Text Available There is a demand for lean construction in Europe; even though lean construction is still an emerging field and there is growing interest, there are no regulations on this topic. The main objective of this research is to regulate this role when in a project and to define and develop a building agent structure, according to the Building Standards Act (LOE by its acronym in Spanish, to be able to incorporate it into the Spanish law, protecting it from civil liabilities. In Spain, there is jurisprudence in civil jurisdiction based on the LOE to acquit or convict building agents, who are defined in the courts as “constructive managers” or similar. For this reason, courts could establish in the future several liabilities for the lean construction specialist and other agents of the project, depending on their actions and based on the implementation of the lean project delivery system, the target value design and the integrated project delivery. Conversely, it is possible that the level of action of the lean construction specialist may comprise design management, construction management and contract management. Accordingly, one or more building agents should be appropriately incorporated into the LOE according to their functions and responsibilities and based on the levels of action of the lean construction specialist. The creation of the following agents is proposed: design manager, construction manager and contract manager, definitions that are developed in this study. These agents are loosely defined, because any project manager, building information modeling manager or similar may act as one or as more-than-one of them. Finally, the creation of the lean construction manager is also proposed, as the agent who takes on the role of the design manager, construction manager and contract manager, but focused on the lean production principles.

In recent years, the potential of stem cell research for tissue engineering-based therapies and regenerative medicine clinical applications has become well established. In 2006, Chung pioneered the first entire organ transplant using adult stem cells and a scaffold for clinical evaluation. With this a new milestone was achieved, with seven patients with myelomeningocele receiving stem cell-derived bladder transplants resulting in substantial improvements in their quality of life. While a bladder is a relatively simple organ, the breakthrough highlights the incredible benefits that can be gained from the cross-disciplinary nature of tissue engineering and regenerative medicine (TERM) that encompasses stem cell research and stem cell bioprocessing. Unquestionably, the development of bioprocess technologies for the transfer of the current laboratory-based practice of stem cell tissue culture to the clinic as therapeutics necessitates the application of engineering principles and practices to achieve control, reproducibility, automation, validation and safety of the process and the product. The successful translation will require contributions from fundamental research (from developmental biology to the 'omics' technologies and advances in immunology) and from existing industrial practice (biologics), especially on automation, quality assurance and regulation. The timely development, integration and execution of various components will be critical-failures of the past (such as in the commercialization of skin equivalents) on marketing, pricing, production and advertising should not be repeated. This review aims to address the principles required for successful stem cell bioprocessing so that they can be applied deftly to clinical applications.

Principles of Bioremediation Assessment

Madsen, E. L.

2001-12-01

Although microorganisms have successfully and spontaneously maintained the biosphere since its inception, industrialized societies now produce undesirable chemical compounds at rates that outpace naturally occurring microbial detoxification processes. This presentation provides an overview of both the complexities of contaminated sites and methodological limitations in environmental microbiology that impede the documentation of biodegradation processes in the field. An essential step toward attaining reliable bioremediation technologies is the development of criteria which prove that microorganisms in contaminated field sites are truly active in metabolizing contaminants of interest. These criteria, which rely upon genetic, biochemical, physiological, and ecological principles and apply to both in situ and ex situ bioremediation strategies include: (i) internal conservative tracers; (ii) added conservative tracers; (iii) added radioactive tracers; (iv) added isotopic tracers; (v) stable isotopic fractionation patterns; (vi) detection of intermediary metabolites; (vii) replicated field plots; (viii) microbial metabolic adaptation; (ix) molecular biological indicators; (x) gradients of coreactants and/or products; (xi) in situ rates of respiration; (xii) mass balances of contaminants, coreactants, and products; and (xiii) computer modeling that incorporates transport and reactive stoichiometries of electron donors and acceptors. The ideal goal is achieving a quantitative understanding of the geochemistry, hydrogeology, and physiology of complex real-world systems.

Effective conservation requires knowledge exchange among scientists and decision-makers to enable learning and support evidence-based decision-making. Efforts to improve knowledge exchange have been hindered by a paucity of empirically-grounded guidance to help scientists and practitioners design and implement research programs that actively facilitate knowledge exchange. To address this, we evaluated the Ningaloo Research Program (NRP), which was designed to generate new scientific knowledge to support evidence-based decisions about the management of the Ningaloo Marine Park in north-western Australia. Specifically, we evaluated (1) outcomes of the NRP, including the extent to which new knowledge informed management decisions; (2) the barriers that prevented knowledge exchange among scientists and managers; (3) the key requirements for improving knowledge exchange processes in the future; and (4) the core capacities that are required to support knowledge exchange processes. While the NRP generated expansive and multidisciplinary science outputs directly relevant to the management of the Ningaloo Marine Park, decision-makers are largely unaware of this knowledge and little has been integrated into decision-making processes. A range of barriers prevented efficient and effective knowledge exchange among scientists and decision-makers including cultural differences among the groups, institutional barriers within decision-making agencies, scientific outputs that were not translated for decision-makers and poor alignment between research design and actual knowledge needs. We identify a set of principles to be implemented routinely as part of any applied research program, including; (i) stakeholder mapping prior to the commencement of research programs to identify all stakeholders, (ii) research questions to be co-developed with stakeholders, (iii) implementation of participatory research approaches, (iv) use of a knowledge broker, and (v) tailored knowledge management

2011-08-01

The Association of American Medical Colleges' Institute for Improving Medical Education's report entitled 'Effective Use of Educational Technology' called on researchers to study the effectiveness of multimedia design principles. These principles were empirically shown to result in superior learning when used with college students in laboratory studies, but have not been studied with undergraduate medical students as participants. A pre-test/post-test control group design was used, in which the traditional-learning group received a lecture on shock using traditionally designed slides and the modified-design group received the same lecture using slides modified in accord with Mayer's principles of multimedia design. Participants included Year 3 medical students at a private, midwestern medical school progressing through their surgery clerkship during the academic year 2009-2010. The medical school divides students into four groups; each group attends the surgery clerkship during one of the four quarters of the academic year. Students in the second and third quarters served as the modified-design group (n=91) and students in the fourth-quarter clerkship served as the traditional-design group (n=39). Both student cohorts had similar levels of pre-lecture knowledge. Both groups showed significant improvements in retention (paffect transfer of learning. Further research on applying the principles of multimedia design to medical education is needed to verify the impact it has on the long-term learning of medical students, as well as its impact on other forms of multimedia instructional programmes used in the education of medical students. © Blackwell Publishing Ltd 2011.

Bioethics emerges about the tecnological problems of acting in human life. Emerges also the problem of the moral limits determination, because they seem exterior of this practice. The Bioethics of Principles, take his rationality of the teleological thinking, and the autonomism. These divergence manifest the epistemological fragility and the great difficulty of hmoralñ thinking. This is evident in the determination of autonomy's principle, it has not the ethical content of Kant's propose. We need a new ethic rationality with a new refelxion of new Principles whose emerges of the basic ethic experiences.

First Principles Prediction of Structure, Structure Selectivity, and Thermodynamic Stability under Realistic Conditions

Energy Technology Data Exchange (ETDEWEB)

Ceder, Gerbrand [Massachusetts Inst. of Technology (MIT), Cambridge, MA (United States). Dept. of Materials and Engineering

2018-01-28

Novel materials are often the enabler for new energy technologies. In ab-initio computational materials science, method are developed to predict the behavior of materials starting from the laws of physics, so that properties can be predicted before compounds have to be synthesized and tested. As such, a virtual materials laboratory can be constructed, saving time and money. The objectives of this program were to develop first-principles theory to predict the structure and thermodynamic stability of materials. Since its inception the program focused on the development of the cluster expansion to deal with the increased complexity of complex oxides. This research led to the incorporation of vibrational degrees of freedom in ab-initio thermodynamics, developed methods for multi-component cluster expansions, included the explicit configurational degrees of freedom of localized electrons, developed the formalism for stability in aqueous environments, and culminated in the first ever approach to produce exact ground state predictions of the cluster expansion. Many of these methods have been disseminated to the larger theory community through the Materials Project, pymatgen software, or individual codes. We summarize three of the main accomplishments.

Laboratory reptile surgery: principles and techniques.

Science.gov (United States)

Alworth, Leanne C; Hernandez, Sonia M; Divers, Stephen J

2011-01-01

Reptiles used for research and instruction may require surgical procedures, including biopsy, coelomic device implantation, ovariectomy, orchidectomy, and esophogostomy tube placement, to accomplish research goals. Providing veterinary care for unanticipated clinical problems may require surgical techniques such as amputation, bone or shell fracture repair, and coeliotomy. Although many principles of surgery are common between mammals and reptiles, important differences in anatomy and physiology exist. Veterinarians who provide care for these species should be aware of these differences. Most reptiles undergoing surgery are small and require specific instrumentation and positioning. In addition, because of the wide variety of unique physiologic and anatomic characteristics among snakes, chelonians, and lizards, different techniques may be necessary for different reptiles. This overview describes many common reptile surgery techniques and their application for research purposes or to provide medical care to research subjects.

The Principle of General Tovariance

Science.gov (United States)

Heunen, C.; Landsman, N. P.; Spitters, B.

2008-06-01

We tentatively propose two guiding principles for the construction of theories of physics, which should be satisfied by a possible future theory of quantum gravity. These principles are inspired by those that led Einstein to his theory of general relativity, viz. his principle of general covariance and his equivalence principle, as well as by the two mysterious dogmas of Bohr's interpretation of quantum mechanics, i.e. his doctrine of classical concepts and his principle of complementarity. An appropriate mathematical language for combining these ideas is topos theory, a framework earlier proposed for physics by Isham and collaborators. Our principle of general tovariance states that any mathematical structure appearing in the laws of physics must be definable in an arbitrary topos (with natural numbers object) and must be preserved under so-called geometric morphisms. This principle identifies geometric logic as the mathematical language of physics and restricts the constructions and theorems to those valid in intuitionism: neither Aristotle's principle of the excluded third nor Zermelo's Axiom of Choice may be invoked. Subsequently, our equivalence principle states that any algebra of observables (initially defined in the topos Sets) is empirically equivalent to a commutative one in some other topos.

Extremum principles for irreversible processes

International Nuclear Information System (INIS)

Hillert, M.; Agren, J.

2006-01-01

Hamilton's extremum principle is a powerful mathematical tool in classical mechanics. Onsager's extremum principle may play a similar role in irreversible thermodynamics and may also become a valuable tool. His principle may formally be regarded as a principle of maximum rate of entropy production but does not have a clear physical interpretation. Prigogine's principle of minimum rate of entropy production has a physical interpretation when it applies, but is not strictly valid except for a very special case

Lines of experimental research in developing mathematical models for estimating internal radiation

International Nuclear Information System (INIS)

Bad'in, V.I.; Ermilov, A.P.; Margulis, U.Ya.; Khrushch, V.T.

The report presents material involved with the statistical approach to the problem of modeling internal radiation and the trend of experimental research dictated by that approach. The content of a radioactive isotope in an organ must be viewed as a random function for which the ratio of two independent incorporations, on the average by probability, corresponds to the ratio of the corresponding amounts of the isotope that have accumulated in the organism. This tenet determines the principle of similarity. Specifically, it follows from it that the distribution of the arbitrary amount in the organism with multiple repetition of the experiment will be subordinate to a log-normal law. Second, the vital condition for creating the quantitative statistical model of the metabolism is a large volume of experimental data. This requires perfection of the unified rapid methods of research

Full Text Available Background: Whilst there are separate streams of established research on lean, green and best practice initiatives, the intersection of these three strategic principles has not been addressed extensively in the past. Objectives: In this study a framework to integrate lean, green and best practice principles into an integrated business model was developed as a strategy for businesses to develop sustainable competitive advantages. Method: A descriptive case study was conducted on Toyota South Africa Motors (TSAM to understand whether a clear link between the company’s environmental approach, lean principles and established best practice culture could be determined. In addition, the case study tested the view that the implementation of these three principles concurrently resulted in improved business results. Results: The main findings of the study revealed that TSAM’s commitment to lean, green and best practice business principles contributed and was directly linked to its business success in terms of sales and market position. Conclusion: It is recommended that businesses implement an integrated lean, green and best practice business model as a strategy to reduce costs and sustainably enhance profitably and competitiveness.

Full Text Available The question to give a convincing assessment of the Rules of the internal controls and present them in the form of principles of organization of internal control. Since the final decision in the form of an exhaustive list and universal principles of internal control is no scientific research continues these principles. It is necessary to examine the logic of the main provisions of the organization's internal control due consideration of the requirements of international practice controls and propose principles of internal control. For this purpose, conducted a critical analysis of the main provisions of internal controls contained in the publications and in the regulations on internal control proceedings. Synthesis of articles of authors of lead scientific and practical journal Ukraine "Accounting and Auditing" for the 1994-2015 biennium pointed out that despite the coverage of current journal articles provisions, principles, requirements, rules and other modern techniques. On internal control and comprehensive set of reasonable response to the organization and classification of internal control is absent. This leads to continue the search key components of the organization's internal control. The above basic concepts in publications on the organization of internal control were used in the formation of a set of principles of control. According to the requirements of the OECD field of internal control includes risk management, cost control, change in control, complete information to guarantee the effectiveness of internal control systems, providing the ability to make decisions and so on. COSO model contains an exhaustive list of five components. The results of the questionnaire trainees have provided compelling arguments for classifying and establishing relevant principles of organization and internal controls were rejected.

[The precautionary principle: advantages and risks].

Science.gov (United States)

Tubiana, M

2001-04-01

The extension of the precautionary principle to the field of healthcare is the social response to two demands of the population: improved health safety and the inclusion of an informed public in the decision-making process. The necessary balance between cost (treatment-induced risk) and benefit (therapeutic effect) underlies all healthcare decisions. An underestimation or an overestimation of cost, i.e. risk, is equally harmful in public healthcare. A vaccination should be prescribed when its beneficial effect outweighs its inevitable risk. Mandatory vaccination, such as in the case of the Hepatitis B virus, is a health policy requiring some courage because those who benefit will never be aware of its positive effect while those who are victims of the risk could resort to litigation. Defense against such accusations requires an accurate assessment of risk and benefit, which underlines the importance of expertise. Even within the framework of the precautionary principle, it is impossible to act without knowledge, or at least a plausible estimation, of expected effects. Recent affairs (blood contamination, transmissible spongiform encephalitis by growth hormone, and new variant of Creutzfeldt-Jacob disease) illustrate that in such cases the precautionary principle would have had limited impact and it is only when enough knowledge was available that effective action could be taken. Likewise, in current debates concerning the possible risks of electromagnetic fields, cellular phones and radon, research efforts must be given priority. The general public understands intuitively the concept of cost and benefit. For example, the possible health risks of oral contraceptives and hormone replacement therapy were not ignored, but the public has judged that their advantages justify the risk. Estimating risk and benefit and finding a balance between risk and preventive measures could help avoid the main drawbacks of the precautionary principle, i.e. inaction and refusal of
