PubMed

du Prel, Jean-Baptist; Röhrig, Bernd; Blettner, Maria

2009-02-01

In the era of evidence-based medicine, one of the most important skills a physician needs is the ability to analyze scientific literature critically. This is necessary to keep medical knowledge up to date and to ensure optimal patient care. The aim of this paper is to present an accessible introduction into critical appraisal of scientific articles. Using a selection of international literature, the reader is introduced to the principles of critical reading of scientific articles in medicine. For the sake of conciseness, detailed description of statistical methods is omitted. Widely accepted principles for critically appraising scientific articles are outlined. Basic knowledge of study design, structuring of an article, the role of different sections, of statistical presentations as well as sources of error and limitation are presented. The reader does not require extensive methodological knowledge. As far as necessary for critical appraisal of scientific articles, differences in research areas like epidemiology, clinical, and basic research are outlined. Further useful references are presented. Basic methodological knowledge is required to select and interpret scientific articles correctly.

[Evaluation of occupational medicine service tasks in the context of the Occupational Medicine Service Act, article 12, on the basis of statistical indicators in the Pomorskie voivodship].

PubMed

Parszuto, Jacek; Jaremin, Bogdan; Tukalska-Parszuto, Maria

2009-01-01

Occupational health service is based on legal regulations. We have made an attempt to estimate the implementation of the tasks resulting from article 12 of the Occupational Medicine Service Act introduced in 1998. In this paper we analyzed statistical data concerning the number of prophylactic health contracts, economic entities and health insurance payers. The data come from the Nofer Institute of Occupational Medicine, Central Statistical Office and Social Insurance Institution. Contract Coverage Rate (CCR) has been introduced for the purpose of this research. The data show that in 2007, the Contract Coverage Rate (CCR) for the Pomorskie voivodeship (province) accounted for 45.7%, with the median value of 14.4% for all voivodeships in Poland. According to the gathered statistical data, it should be concluded that the implementation of article 12 is insufficient. The amendment to the Act introducing the provision on written contracts is an opportunity to provide an effective mechanism, by which the present situation can be improved and the rates raised to a satisfactory level.

PROCESS OF PRODUCING REFRACTORY URANIUM OXIDE ARTICLES

DOEpatents

Hamilton, N.E.

1957-12-01

A method is presented for fabricating uranium oxide into a shaped refractory article by introducing a uranium halide fluxing reagent into the uranium oxide, and then mixing and compressing the materials into a shaped composite mass. The shaped mass of uranium oxide and uranium halide is then fired at an elevated temperature so as to form a refractory sintered article. It was found in the present invention that the introduction of a uraninm halide fluxing agent afforded a fluxing action with the uranium oxide particles and that excellent cohesion between these oxide particles was obtained. Approximately 90% of uranium dioxide and 10% of uranium tetrafluoride represent a preferred composition.

Coining and defining novel nursing terminology. Part 2: critical incident nursing intervention.

PubMed

Wong, Elizabeth

2008-01-01

In the second of a three-part series, a novel nursing terminology is introduced and proposed for inclusion in the Nursing Interventions Classification (NIC): Critical incident nursing intervention (CINI), defined as any indirect or direct care registered nurse-initiated treatment, based upon clinical judgment and knowledge that a registered nurse performs in response to a critical incident nursing diagnosis (CIND). A CIND is defined as recognition of an acute life-threatening event that occurs as a result of disease, surgery, treatment, or medication. The literature, research studies, meta-analyses from a variety of disciplines, and personal clinical experience serve as the data sources for this article. The current nursing interventions in the NIC are inaccurate or inadequate for describing nursing care during life-threatening situations. The lack of standardized nursing terminology creates a barrier that may impede critical communication and patient care during life-threatening situations. Coining and defining novel nursing terminology, CINI, for patient care during life-threatening situations is important and fills the gap in the current standardized nursing terminology. Refining the NIC will permit nursing researchers, among others, to conduct studies on nursing interventions in conjunction with the proposed novel nursing terminology, CINI. The first article in this series (Part 1) introduced the novel nursing terminology: CIND; the present article (Part 2) introduces the novel nursing terminology: CINI; and the third article in this series (Part 3) will introduce the novel nursing terminology: critical incident control.

Missing data imputation: focusing on single imputation.

Zhang, Zhongheng

2016-01-01

Complete case analysis is widely used for handling missing data, and it is the default method in many statistical packages. However, this method may introduce bias and some useful information will be omitted from analysis. Therefore, many imputation methods are developed to make gap end. The present article focuses on single imputation. Imputations with mean, median and mode are simple but, like complete case analysis, can introduce bias on mean and deviation. Furthermore, they ignore relationship with other variables. Regression imputation can preserve relationship between missing values and other variables. There are many sophisticated methods exist to handle missing values in longitudinal data. This article focuses primarily on how to implement R code to perform single imputation, while avoiding complex mathematical calculations.

Aesthetic Diagnosis in Gestalt Therapy †

PubMed Central

Roubal, Jan; Francesetti, Gianni; Gecele, Michela

2017-01-01

The diagnostic process in psychotherapy using the aesthetic evaluation is described in this article. Unlike the classical diagnostic process, which presents a result of comparing clinicians´ observations with a diagnostic system (DSM, ICD, etc.), the aesthetic evaluation is a pre-reflexive, embodied, and preverbal process. A Gestalt Therapy theoretical frame is used to introduce a concept of the aesthetic diagnostic process. During this process, the clinicians use their own here-and-now presence, which takes part in the co-creation of the shared relational field during the therapeutic session. A specific procedure of the aesthetic evaluation is introduced. The clinical work with depressed clients is presented to illustrate this perspective. PMID:29039752

Finance for practicing radiologists.

Berlin, Jonathan W; Lexa, Frank James

2005-03-01

This article reviews basic finance for radiologists. Using the example of a hypothetical outpatient computed tomography center, readers are introduced to the concept of net present value. This concept refers to the current real value of anticipated income in the future, realizing that revenue in the future has less value than it does today. Positive net present value projects add wealth to a practice and should be pursued. The article details how costs and revenues for a hypothetical outpatient computed tomography center are determined and elucidates the difference between fixed costs and variable costs. The article provides readers with the steps used to calculate the break-even volume for an outpatient computed tomography center given situation-specific assumptions regarding staff, equipment lease rates, rent, and third-party payer mix.

Porous article with surface functionality and method for preparing same

Koontz, Steven L. (Inventor)

2000-01-01

Porous organic articles having no surface functionality may be treated by remote plasma discharge to thereby introduce functionality to the surface of the article. The functionality is introduced throughout the article's surface, including the exterior surface and the surfaces of the pores. Little or no degradation of the porous organic article occurs as a result of the functionalization. Amino, hydroxyl, carbonyl and carboxyl groups may be introduced to the article. In this way, an essentially inert hydrophobic porous article, made from, for example, polyethylene, can have its surface modified so that the surface becomes hydrophilic. The remote plasma discharge process causes essentially no change in the bulk properties of the organic article. The remote plasma discharge process is preferably conducted so that no photons, and particularly no ultraviolet radiation, is transmitted from the plasma glow to the porous article. The surface-functionalized article may be used, for example, as a solid support in organic synthesis or in the chromatographic purification of organic or biochemicals.

Drug safety: withdrawn medications are only part of the picture.

PubMed

Rawson, Nigel S B

2016-02-13

In a research article published in BMC Medicine, Onakpoya and colleagues provide a historical review of withdrawals of medications for safety reasons. However, withdrawn medications are only one part of the picture about how regulatory agencies manage drug risks. Moreover, medications introduced before the increased pre-marketing regulations and post-marketing monitoring systems instituted after the thalidomide tragedy have little relevance when considering the present drug safety picture because the circumstances under which they were introduced were completely different. To more fully understand drug safety management and regulatory agency actions, withdrawals should be evaluated within the setting and timeframe in which the medications are approved, which requires information about approvals and safety warnings. Studies are needed that provide a more comprehensive current picture of the identification and evaluation of drug safety risks as well as how regulatory agencies deal with them.

Trajectory optimization of spacecraft high-thrust orbit transfer using a modified evolutionary algorithm

NASA Astrophysics Data System (ADS)

Shirazi, Abolfazl

2016-10-01

This article introduces a new method to optimize finite-burn orbital manoeuvres based on a modified evolutionary algorithm. Optimization is carried out based on conversion of the orbital manoeuvre into a parameter optimization problem by assigning inverse tangential functions to the changes in direction angles of the thrust vector. The problem is analysed using boundary delimitation in a common optimization algorithm. A method is introduced to achieve acceptable values for optimization variables using nonlinear simulation, which results in an enlarged convergence domain. The presented algorithm benefits from high optimality and fast convergence time. A numerical example of a three-dimensional optimal orbital transfer is presented and the accuracy of the proposed algorithm is shown.

Introducing Teamwork Challenges in Simulation Using Game Cards.

PubMed

Chang, Todd P; Kwan, Karen Y; Liberman, Danica; Song, Eric; Dao, Eugene H; Chung, Dayun; Morton, Inge; Festekjian, Ara

2015-08-01

Poor teamwork and communication during resuscitations are linked to patient safety problems and poorer outcomes. We present a novel simulation-based educational intervention using game cards to introduce challenges in teamwork. This intervention uses sets of game cards that designate roles, limitations, or communication challenges designed to introduce common communication or teamwork problems. Game cards are designed to be applicable for any simulation-based scenario and are independent from patient physiology. In our example, participants were pediatric emergency medicine fellows undergoing simulation training for orientation. We describe the use of card sets in different scenarios with increasing teamwork challenge and difficulty. Both postscenario and summative debriefings were facilitated to allow participants to reflect on their performance and discover ways to apply their strategies to real resuscitations. In this article, we present our experience with the novel use of game cards to modify simulation scenarios to improve communication and teamwork skills.

Legislation for Youth Sport Concussion in Canada: Review, Conceptual Framework, and Recommendations.

PubMed

Russell, Kelly; Ellis, Michael J; Bauman, Shannon; Tator, Charles H

2017-05-01

In this article, we conduct a review of introduced and enacted youth concussion legislation in Canada and present a conceptual framework and recommendations for future youth sport concussion laws. We conducted online searches of federal, provincial, and territorial legislatures to identify youth concussion bills that were introduced or successfully enacted into law. Internet searches were carried out from July 26 and 27, 2016. Online searches identified six youth concussion bills that were introduced in provincial legislatures, including two in Ontario and Nova Scotia and one each in British Columbia and Quebec. One of these bills (Ontario Bill 149, Rowan's Law Advisory Committee Act, 2016) was enacted into provincial law; it is not actual concussion legislation, but rather a framework for possible enactment of legislation. Two bills have been introduced in federal parliament but neither bill has been enacted into law. At present, there is no provincial or federal concussion legislation that directly legislates concussion education, prevention, management, or policy in youth sports in Canada. The conceptual framework and recommendations presented here should be used to guide the design and implementation of future youth sport concussion laws in Canada.

Students' Views and Attitudes Towards the Communication Code Used in Press Articles About Science

NASA Astrophysics Data System (ADS)

Halkia, Krystallia; Mantzouridis, Dimitris

2005-10-01

The present research was designed to investigate the reaction of secondary school students to the communication code that the press uses in science articles: it attempts to trace which communication techniques can be of potential use in science education. The sample of the research consists of 351 secondary school students. The research instrument is a questionnaire, which attempts to trace students’ preferences regarding newspaper science articles, to explore students’ attitudes towards the science articles published in the press and to investigate students’ reactions towards four newspaper science articles. These articles deal with different aspects of science and reflect different communication strategies. The results of the research reveal that secondary school students view the communication codes used in press science articles as being more interesting and comprehensible than those of their science textbooks. Predominantly, they do not select science articles that present their data in a scientific way (diagrams and abstract graphs). On the contrary, they do select science articles and passages in them, which use an emotional/‘poetic’ language with a lot of metaphors and analogies to introduce complex science concepts. It also seems that the narrative elements found in popularized science articles attract students’ interest and motivate them towards further reading.

Introducing evidence-based dentistry to dental students using histology.

PubMed

Lallier, Thomas E

2014-03-01

The expansion of evidence-based dentistry (EBD) is essential to the continued growth and development of the dental profession. Expanding EBD requires increased emphasis on critical thinking skills during dental education, as noted in the American Dental Education Association's Competencies for the New General Dentist. In order to achieve this goal, educational exercises must be introduced to increase the use of critical thinking skills early in the dental curriculum, with continued reinforcement as students progress through subsequent years. Described in this article is one approach to increasing student exposure to critical thinking during the early basic science curriculum-specifically, within the confines of a traditional histology course. A method of utilizing the medical and dental research literature to reinforce and enliven the concepts taught in histology is described, along with an approach for using peer-to-peer presentations to demonstrate the tools needed to critically evaluate research studies and their presentation in published articles. This approach, which could be applied to any basic science course, will result in a stronger foundation on which students can build their EBD and critical thinking skills.

SPOT: Optimization Tool for Network Adaptable Security

NASA Astrophysics Data System (ADS)

Ksiezopolski, Bogdan; Szalachowski, Pawel; Kotulski, Zbigniew

Recently we have observed the growth of the intelligent application especially with its mobile character, called e-anything. The implementation of these applications provides guarantee of security requirements of the cryptographic protocols which are used in the application. Traditionally the protocols have been configured with the strongest possible security mechanisms. Unfortunately, when the application is used by means of the mobile devices, the strongest protection can lead to the denial of services for them. The solution of this problem is introducing the quality of protection models which will scale the protection level depending on the actual threat level. In this article we would like to introduce the application which manages the protection level of the processes in the mobile environment. The Security Protocol Optimizing Tool (SPOT) optimizes the cryptographic protocol and defines the protocol version appropriate to the actual threat level. In this article the architecture of the SPOT is presented with a detailed description of the included modules.

Mass spectrometry in plant metabolomics strategies: from analytical platforms to data acquisition and processing.

PubMed

Ernst, Madeleine; Silva, Denise Brentan; Silva, Ricardo Roberto; Vêncio, Ricardo Z N; Lopes, Norberto Peporine

2014-06-01

Covering: up to 2013. Plant metabolomics is a relatively recent research field that has gained increasing interest in the past few years. Up to the present day numerous review articles and guide books on the subject have been published. This review article focuses on the current applications and limitations of the modern mass spectrometry techniques, especially in combination with electrospray ionisation (ESI), an ionisation method which is most commonly applied in metabolomics studies. As a possible alternative to ESI, perspectives on matrix-assisted laser desorption/ionisation mass spectrometry (MALDI-MS) in metabolomics studies are introduced, a method which still is not widespread in the field. In metabolomics studies the results must always be interpreted in the context of the applied sampling procedures as well as data analysis. Different sampling strategies are introduced and the importance of data analysis is illustrated in the example of metabolic network modelling.

Integrating strategic and tactical decisions in livestock supply chain using bi-level programming, case study: Iran poultry supply chain.

PubMed

Teimoury, Ebrahim; Jabbarzadeh, Armin; Babaei, Mohammadhosein

2017-01-01

Inventory management has frequently been targeted by researchers as one of the most pivotal problems in supply chain management. With the expansion of research studies on inventory management in supply chains, perishable inventory has been introduced and its fundamental differences from non-perishable inventory have been emphasized. This article presents livestock as a type of inventory that has been less studied in the literature. Differences between different inventory types, affect various levels of strategic, tactical and operational decision-making. In most articles, different levels of decision-making are discussed independently and sequentially. In this paper, not only is the livestock inventory introduced, but also a model has been developed to integrate decisions across different levels of decision-making using bi-level programming. Computational results indicate that the proposed bi-level approach is more efficient than the sequential decision-making approach.

Data management by using R: big data clinical research series.

PubMed

Zhang, Zhongheng

2015-11-01

Electronic medical record (EMR) system has been widely used in clinical practice. Instead of traditional record system by hand writing and recording, the EMR makes big data clinical research feasible. The most important feature of big data research is its real-world setting. Furthermore, big data research can provide all aspects of information related to healthcare. However, big data research requires some skills on data management, which however, is always lacking in the curriculum of medical education. This greatly hinders doctors from testing their clinical hypothesis by using EMR. To make ends meet, a series of articles introducing data management techniques are put forward to guide clinicians to big data clinical research. The present educational article firstly introduces some basic knowledge on R language, followed by some data management skills on creating new variables, recoding variables and renaming variables. These are very basic skills and may be used in every project of big data research.

A Current Approach to Halitosis and Oral Malodor- A Mini Review.

PubMed

Bicak, Damla Aksit

2018-01-01

Halitosis, in other words, oral malodor is an important multifactorial health problem affecting the psychological and social life of individuals and is the most common reason for referral to dentists after dental caries and periodontal diseases. The objective of this review was to present and discuss conventional and recently introduced information about the types, causes, detection and treatment methods of halitosis. An expanded literature review was conducted which targeted all articles published in peer-reviewed journals relating to the topic of halitosis. Only articles written in Turkish and English languages were considered. The review itself began with a search of relevant subject headings such as 'halitosis, oral malodor, volatile sulfur compounds in PubMed/Medline, Scopus, Google Scholar and Tubitak Ulakbim databases. A hand search of references was also performed. When search results are combined, the total number of relevant literature was found to be 4646 abstracts and 978 full-text articles. Abstracts, editorial letters were not included and about half of full-text articles were not related to dental practice. Among the remaining 124 full-text articles, duplicated articles and articles written other than Turkish and English languages were removed and 54 full-text articles were used for this review. According to the reviewed articles, both conventional and new methods were introduced in the management of halitosis. However, conventional methods seem to be more effective and widely used in the diagnosis and treatment of halitosis. As being first line professionals, dentists must analyze and treat oral problems which may be responsible for the patient's malodor, and should inform the patient about halitosis causes and oral hygiene procedures (tooth flossing, tongue cleaning, appropriate mouthwash and toothpaste selection and use) and if the problem persists, they should consult to a medical specialist.

The Mutable Nature of Risk and Acceptability: A Hybrid Risk Governance Framework.

PubMed

Wong, Catherine Mei Ling

2015-11-01

This article focuses on the fluid nature of risk problems and the challenges it presents to establishing acceptability in risk governance. It introduces an actor-network theory (ANT) perspective as a way to deal with the mutable nature of risk controversies and the configuration of stakeholders. To translate this into a practicable framework, the article proposes a hybrid risk governance framework that combines ANT with integrative risk governance, deliberative democracy, and responsive regulation. This addresses a number of the limitations in existing risk governance models, including: (1) the lack of more substantive public participation throughout the lifecycle of a project; (2) hijacking of deliberative forums by particular groups; and (3) the treatment of risk problems and their associated stakeholders as immutable entities. The framework constitutes a five-stage process of co-selection, co-design, co-planning, and co-regulation to facilitate the co-production of collective interests and knowledge, build capacities, and strengthen accountability in the process. The aims of this article are twofold: conceptually, it introduces a framework of risk governance that accounts for the mutable nature of risk problems and configuration of stakeholders. In practice, this article offers risk managers and practitioners of risk governance a set of procedures with which to operationalize this conceptual approach to risk and stakeholder engagement. © 2015 Society for Risk Analysis.

Optimization of a dual mode Rowland mount spectrometer used in the 120-950 nm wavelength range

NASA Astrophysics Data System (ADS)

McDowell, M. W.; Bouwer, H. K.

In a recent article, several configurations were described whereby a Rowland mount spectrometer could be modified to cover a wavelength range of 120-950 nm. In one of these configurations, large additional image aberration is introduced which severely limits the spectral resolving power. In the present article, the theoretical imaging properties of this configuration are considered and a simple method is proposed to reduce this aberration. The optimized system possesses an image quality similar to the conventional Rowland mount with the image surface slightly displaced from the Rowland circle but concentric to it.

2015-05-01

The process underlying desistance is still a strong subject of debate. This article seeks to introduce several core concepts of Archer's morphogenic approach to study how people desist from crime. At first, it discusses the primary existing theories of desistance. Then, this article demonstrates the usefulness of this approach by presenting empirical evidence drawn from semistructured interviews collected with 29 men who desisted from crime in an eastern province of Canada. The study demonstrates how this alternative approach allows for the consolidation of existing knowledge on desistance. Then implication of these findings for both theory and practice are discussed. © The Author(s) 2013.

Extraction of Boron Nitride Nanotubes and Fabrication of Macroscopic Articles Using Chlorosulfonic Acid.

PubMed

Adnan, Mohammed; Marincel, Daniel M; Kleinerman, Olga; Chu, Sang-Hyon; Park, Cheol; Hocker, Samuel J A; Fay, Catharine; Arepalli, Sivaram; Talmon, Yeshayahu; Pasquali, Matteo

2018-03-14

Due to recent advances in high-throughput synthesis, research on boron nitride nanotubes (BNNTs) is moving toward applications. One future goal is the assembly of macroscopic articles of high-aspect-ratio, pristine BNNTs. However, these articles are presently unattainable because of insufficient purification and fabrication methods. We introduce a solution process for extracting BNNTs from synthesis impurities without sonication or the use of surfactants and proceed to convert the extracted BNNTs into thin films. The solution process can also be used to convert as-synthesized material-which contains significant amounts of hexagonal boron nitride ( h-BN)-into mats and aerogels with controllable structure and dimension. The solution extraction method, combined with further advances in synthesis and purification, contributes to the development of all-BNNT macroscopic articles, such as fibers and 3-D structures.

An instructive model of entropy

NASA Astrophysics Data System (ADS)

Zimmerman, Seth

2010-09-01

This article first notes the misinterpretation of a common thought experiment, and the misleading comment that 'systems tend to flow from less probable to more probable macrostates'. It analyses the experiment, generalizes it and introduces a new tool of investigation, the simplectic structure. A time-symmetric model is built upon this structure, yielding several non-intuitive results. The approach is combinatorial rather than statistical, and assumes that entropy is equivalent to 'missing information'. The intention of this article is not only to present interesting results, but also, by deliberately starting with a simple example and developing it through proof and computer simulation, to clarify the often confusing subject of entropy. The article should be particularly stimulating to students and instructors of discrete mathematics or undergraduate physics.

Translating human biology (introduction to special issue).

PubMed

Brewis, Alexandra A; Mckenna, James J

2015-01-01

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

The use of the Novosol process for the treatment of polluted marine sediment.

The work presented in this article concerns polluted marine sediments. The article is divided into three parts. The first part discusses existing industrial procedures of treatment. The second part introduces the Novosol((R)) process, which was used for the treatment of polluted marine sediments. This process is based on the stabilization of heavy metals in the solid matrix by phosphatation and the destruction of organic matter by calcination. Finally, after a comparison had been made between environmental results obtained on both polluted marine sediments and inert ones, treated sediments were introduced in the production of clay bricks. The results obtained show that the Novosol process leads to the immobilization of most heavy metals and can be considered as an efficient tool for the stabilisation of polluted marine sediment. Thus, the results of physical and mechanical tests as compressive strength and water absorption indicate that performances obtained were comparable to standard brick values. These results confirm that, once treated, polluted sediments can be recycled.

Outcomes for a transitional living program serving LGBTQ youth in New York City.

PubMed

Nolan, Theresa C

2006-01-01

Providing stable housing for runaway and homeless youth is a major function of a transitional living program. This article introduces the focus of one program working with LGBTQ youth in New York City and discusses some issues to consider when working with this population. The article also presents data associated with young people's lives after discharge. In any discussion of outcomes, both reason for discharge and length of stay play important roles in whether or not an exit is safe. Regardless of these two elements, the places youth move to when leaving programs are crucial to their safety and well-being. The exit can be safe even when a young person is discharged early from a program. This article presents types of exits, as well as status of employment and school enrollment at exit. Some youth and staff-identified lessons gained in the program also are discussed in detail. Types of aftercare services sought by discharged youth are specified. This article also describes any differences in outcomes for youth with and without foster care experience.

Epigenomic Susceptibility to the Social World: Plausible Paths to a "Newest Morbidity".

PubMed

Boyce, W Thomas

2017-08-01

This article-presented on the celebratory occasion of Dr Robert Haggerty's 91st birthday-describes how a 1962 article by Dr Haggerty and his colleague Dr Roger Meyer launched a previously unexplored, pediatric research enterprise by asserting that: "There are little precise data to explain why one person becomes ill with an infecting agent and another not." Noting a prospective association between family stressors and the acquisition of β-hemolytic streptococcal infections, the article introduced a generation of young academic pediatricians-the author of the present article among them-to the possibility of causal linkages among children's adversity exposures, compromised immunological processes, and the development of immune-mediated, acute or chronic diseases of childhood. That research agenda has led, over the past 40 years, to the advent of psychoneuroimmunology as a field of study, to the recognition of childhood stress and adversity as potential etiologic agents among childhood morbidities, and to the discovery of differential susceptibility to social adversities within populations of children.

Venegas-Andraca, Salvador E.; Cruz-Santos, William; McGeoch, Catherine; Lanzagorta, Marco

2018-04-01

A central goal in quantum computing is the development of quantum hardware and quantum algorithms in order to analyse challenging scientific and engineering problems. Research in quantum computation involves contributions from both physics and computer science; hence this article presents a concise introduction to basic concepts from both fields that are used in annealing-based quantum computation, an alternative to the more familiar quantum gate model. We introduce some concepts from computer science required to define difficult computational problems and to realise the potential relevance of quantum algorithms to find novel solutions to those problems. We introduce the structure of quantum annealing-based algorithms as well as two examples of this kind of algorithms for solving instances of the max-SAT and Minimum Multicut problems. An overview of the quantum annealing systems manufactured by D-Wave Systems is also presented.

Nurse practitioners in aged care: documentary analysis of successful project proposals.

PubMed

Clark, Shannon J; Parker, Rhian M; Davey, Rachel

2014-11-01

Meeting the primary health care needs of an aging population is an increasing challenge for many Western nations. In Australia, the federal government introduced a program to develop, test, and evaluate nurse practitioner models in aged care settings. In this article, we present a documentary analysis of 32 project proposals awarded funding under the Nurse Practitioner-Aged Care Models of Practice Program. Successfully funded models were diverse and were operated by a range of organizations across Australia. We identified three key priorities as underlying the proposed models: "The right care," "in the right place," and "at the right time." In this article, we explore how these priorities were presented by different applicants in different ways. Through the presentation of their models, the program's applicants identified and proposed to address current gaps in health services. Applicants contrasted their proposed models with available services to create persuasive and competitive applications for funding. © The Author(s) 2014.

BFT replication resistant to MAC attacks

NASA Astrophysics Data System (ADS)

Zbierski, Maciej

2016-09-01

Over the last decade numerous Byzantine fault-tolerant (BFT) replication protocols have been proposed in the literature. However, the vast majority of these solutions reuse the same authentication scheme, which makes them susceptible to a so called MAC attack. Such vulnerability enables malicious clients to undetectably prevent the replicated service from processing incoming client requests, and consequently making it permanently unavailable. While some BFT protocols attempted to address this issue by using different authentication mechanisms, they at the same time significantly degraded the performance achieved in correct environments. This article presents a novel adaptive authentication mechanism which can be combined with practically any Byzantine fault-tolerant replication protocol. Unlike previous solutions, the proposed scheme dynamically switches between two operation modes to combine high performance in correct environments and liveness during MAC attacks. The experiment results presented in the article demonstrate that the proposed mechanism can sufficiently tolerate MAC attacks without introducing any observable overhead whenever no faults are present.

The transformation of targeted killing and international order.

PubMed

Senn, Martin; Troy, Jodok

2017-05-04

This article introduces the special issue's question of whether and how the current transformation of targeted killing is transforming the global international order and provides the conceptual ground for the individual contributions to the special issue. It develops a two-dimensional concept of political order and introduces a theoretical framework that conceives the maintenance and transformation of international order as a dynamic interplay between its behavioral dimension in the form of violence and discursive processes and its institutional dimension in the form of ideas, norms, and rules. The article also conceptualizes targeted killing and introduces a typology of targeted-killing acts on the basis of their legal and moral legitimacy. Building on this conceptual groundwork, the article takes stock of the current transformation of targeted killing and summarizes the individual contributions to this special issue.

Musculoskeletal ultrasound and other imaging modalities in rheumatoid arthritis.

PubMed

Ohrndorf, Sarah; Werner, Stephanie G; Finzel, Stephanie; Backhaus, Marina

2013-05-01

This review refers to the use of musculoskeletal ultrasound in patients with rheumatoid arthritis (RA) both in clinical practice and research. Furthermore, other novel sensitive imaging modalities (high resolution peripheral quantitative computed tomography and fluorescence optical imaging) are introduced in this article. Recently published ultrasound studies presented power Doppler activity by ultrasound highly predictive for later radiographic erosions in patients with RA. Another study presented synovitis detected by ultrasound being predictive of subsequent structural radiographic destruction irrespective of the ultrasound modality (grayscale ultrasound/power Doppler ultrasound). Further studies are currently under way which prove ultrasound findings as imaging biomarkers in the destructive process of RA. Other introduced novel imaging modalities are in the validation process to prove their impact and significance in inflammatory joint diseases. The introduced imaging modalities show different sensitivities and specificities as well as strength and weakness belonging to the assessment of inflammation, differentiation of the involved structures and radiological progression. The review tries to give an answer regarding how to best integrate them into daily clinical practice with the aim to improve the diagnostic algorithms, the daily patient care and, furthermore, the disease's outcome.

Bringing the best of medical librarianship to the patient team.

PubMed

Shearer, Barbara S; Seymour, Anne; Capitani, Cheryl

2002-01-01

This article introduces a series of articles examining the state of the medical library profession as practiced in the clinical context. It is widely understood that many changes across the spectrum of medical librarianship practice have been brought about by both technological advances and economic realities. These changes have created strains felt by many in the profession. Discussions of evolving roles for medical librarians that have gone on for years have taken on a new sense of urgency, not just because support of library services is at stake, but also because new opportunities, which many are eager to explore, await librarians. In June 2000, an editorial appearing in a mainstream medical journal proposed a reinvention of clinical librarianship that, if designed as presented in the editorial, would have a dramatic effect on current hospital-based library practice. This series of articles was developed in an effort to provide thoughtful consideration of the "informationist" model and to present new ways to look at the core competencies that define the profession.

This article reports the success, or otherwise, of strategies implemented to sustain nursing grand rounds in a large regional health service in North Queensland, Australia. Nursing grand rounds had been introduced in late 2010 to increase nurses' engagement with research and evidence-based practice. Although the format, topics, and purpose of grand rounds have changed, attendees continue to positively evaluate each presentation. However, after 5 years, the initiative has expanded and somewhat modified its focus. This article describes these changes and proposes options for the future progression of this professional development activity. J Contin Educ Nurs. 2016;47(7):316-320.

The disasters of war in Darfur, 1950-2004.

PubMed

Reyna, Stephen P

2010-01-01

This article investigates the conflict that had been developing since the 1950s in Darfur and which in 2003 and 2004 burst into intense warfare. A 'complex-structuring of violence' standpoint explains the warfare. The argument is organised in two parts. The first section formulates the position by introducing Darfur, next evaluating the prevailing barbarisation perspective's attempts to explicate Darfur warring and, finally, formally presenting the complex structuring standpoint. The second section offers evidence bearing upon this standpoint. This involves information showing that four interrelated structural realms form a causal complex producing the violence. The article ends with discussion of the US government's role in Darfurian disasters of war.

Cultural relativism and cultural diversity: implications for nursing practice.

PubMed

Baker, C

1997-09-01

This article examines the doctrine of cultural relativism in nursing practice. To introduce the issue, an overview of the intellectual history of cultural relativism is presented. The academic themes of the debate surrounding cultural relativism are illustrated with an example of the social controversy in France involving cultural relativism as used to defend the practice of female genital excision among immigrant communities. The dilemma faced by nursing in making cross-cultural judgments is then examined in the light of the academic and social debates. The article concludes with a theoretical resolution of the issue of cultural relativism for nursing practice that is based on hermeneutic philosophy.

In this article, I use a new book about Jean Piaget to introduce a new historical method: examining "psychological factories." I also discuss some of the ways that "Great Men" are presented in the literature, as well as opportunities for new projects if one approaches the history of the discipline differently and examines the conditions that made that greatness possible. To that end, the article includes many details about Piaget that have never before been discussed in English. Attention is drawn, in particular, to Piaget's collaborators: the hundreds of workers at his factory in Geneva, many of whom were women. (PsycINFO Database Record (c) 2012 APA, all rights reserved).

Iodine Beam Dump Design and Fabrication

NASA Technical Reports Server (NTRS)

Polzin, K. A.; Bradley, D. E.

2017-01-01

During the testing of electric thrusters, high-energy ions impacting the walls of a vacuum chamber can cause corrosion and/or sputtering of the wall materials, which can damage the chamber walls. The sputtering can also introduce the constituent materials of the chamber walls into an experiment, with those materials potentially migrating back to the test article and coating it with contaminants over time. The typical method employed in this situation is to install a beam dump fabricated from materials that have a lower sputter yield, thus reducing the amount of foreign material that could migrate towards the test article or deposit on anything else present in the vacuum facility.

Cultivating Parabolas in the Parlor Garden: Reconciling Mathematics Education and Feminine Ideals in Nineteenth-Century America

NASA Astrophysics Data System (ADS)

Fiss, Andrew

2014-02-01

This article introduces the justification problem for mathematics, which it explores through the case study of 1820s-1840s rationales for the teaching of mathematics to women in the United States. It argues that, while educators in the 1820s justified women's studies through mental discipline (a common reason for men's study), those of the 1830s-1840s increasingly relied on separate, gendered justifications, tied to emerging ideals of middle-class femininity. This article therefore emphasizes the contingency of the justification problem, which serves to break the present-day cycle of gender stereotypes regarding mathematics.

Structured dyadic behavior therapy processes for ADHD intervention.

PubMed

Curtis, David F

2014-03-01

Children with Attention-Deficit/Hyperactivity Disorder (ADHD) present significant problems with behavioral disinhibition that often negatively affect their peer relationships. Although behavior therapies for ADHD have traditionally aimed to help parents and teachers better manage children's ADHD-related behaviors, therapy processes seldom use peer relationships to implement evidence-based behavioral principles. This article introduces Structured Dyadic Behavior Therapy as a milieu for introducing effective behavioral techniques within a socially meaningful context. Establishing collaborative behavioral goals, benchmarking, and redirection strategies are discussed to highlight how in-session dyadic processes can be used to promote more meaningful reinforcement and change for children with ADHD. Implications for improving patient care, access to care, and therapist training are also discussed.

Higher cognitive function in human brain is one of well-developed fields of neuroscience research in the 21st century. Especially functional magnetic resonance imaging (fMRI) and near infrared recording system have brought so many non-clinical researchers whose background is such as cognitive psychology, economics, politics, pedagogy, and so on, to the human brain mapping study. Authors have introduced the ethical issues related to incidental findings during the fMRI recording for non-clinical purpose, which is a typical problem derived from such expanded human brain research under non clinical condition, that is, neuroethics. In the present article we would introduce neuroethical issues in contexts of "out of clinic" and "beyond academia".

2016-02-01

This article presents a review of our present understanding of the spin structure of the unpolarized hadron. Particular attention is paid to the quark sector at leading twist, namely, the quark Boer-Mulders function, which describes the transverse polarization of the quark inside an unpolarized hadron. After introducing the operator definition of the Boer-Mulders function, a detailed treatment of different non-perturbative calculations of the Boer-Mulders functions is provided. The phenomenology in Drell-Yan processes and semi-inclusive leptoproduction, including the extraction of the quark and antiquark Boer-Mulders functions from experimental data, is presented comprehensively. Finally, prospects for future theoretical studies and experimental measurements are presented in brief.

The purpose of this article is to introduce the methods used and challenges confronted by the authors of this two-part series of articles describing the results of analyses of measurement equivalence of the short form scales from the Patient Reported Outcomes Measurement Information System® (PROMIS®). Qualitative and quantitative approaches used to examine differential item functioning (DIF) are reviewed briefly. Qualitative methods focused on generation of DIF hypotheses. The basic quantitative approaches used all rely on a latent variable model, and examine parameters either derived directly from item response theory (IRT) or from structural equation models (SEM). A key methods focus of these articles is to describe state-of-the art approaches to examination of measurement equivalence in eight domains: physical health, pain, fatigue, sleep, depression, anxiety, cognition, and social function. These articles represent the first time that DIF has been examined systematically in the PROMIS short form measures, particularly among ethnically diverse groups. This is also the first set of analyses to examine the performance of PROMIS short forms in patients with cancer. Latent variable model state-of-the-art methods for examining measurement equivalence are introduced briefly in this paper to orient readers to the approaches adopted in this set of papers. Several methodological challenges underlying (DIF-free) anchor item selection and model assumption violations are presented as a backdrop for the articles in this two-part series on measurement equivalence of PROMIS measures.

Mokros, A; Osterheider, M; Nitschke, J

2012-03-01

Pedophilia is a disorder of sexual preference that increases the risk for committing sexual offenses against children. Consequently, pedophilia is not only relevant in psychiatric therapy and prognostics, but also greatly influences the public attitude towards criminality. Public opinion seems to equate pedophilia with child sexual abuse and vice versa which leads to stigmatization of patients and may impede treatment. The present paper provides information on recent studies on the potential origins of the disorder and introduces new diagnostic methods. Moreover, the article presents estimates on the prevalence of pedophilic sexual interest.

The transformation of targeted killing and international order

PubMed Central

Senn, Martin; Troy, Jodok

2017-01-01

ABSTRACT This article introduces the special issue’s question of whether and how the current transformation of targeted killing is transforming the global international order and provides the conceptual ground for the individual contributions to the special issue. It develops a two-dimensional concept of political order and introduces a theoretical framework that conceives the maintenance and transformation of international order as a dynamic interplay between its behavioral dimension in the form of violence and discursive processes and its institutional dimension in the form of ideas, norms, and rules. The article also conceptualizes targeted killing and introduces a typology of targeted-killing acts on the basis of their legal and moral legitimacy. Building on this conceptual groundwork, the article takes stock of the current transformation of targeted killing and summarizes the individual contributions to this special issue. PMID:29097903

Ecological risk assessment conceptual model formulation for nonindigenous species.

PubMed

Landis, Wayne G

2004-08-01

This article addresses the application of ecological risk assessment at the regional scale to the prediction of impacts due to invasive or nonindigenous species (NIS). The first section describes risk assessment, the decision-making process, and introduces regional risk assessment. A general conceptual model for the risk assessment of NIS is then presented based upon the regional risk assessment approach. Two diverse examples of the application of this approach are presented. The first example is based upon the dynamics of introduced plasmids into bacteria populations. The second example is the application risk assessment approach to the invasion of a coastal marine site of Cherry Point, Washington, USA by the European green crab. The lessons learned from the two examples demonstrate that assessment of the risks of invasion of NIS will have to incorporate not only the characteristics of the invasive species, but also the other stresses and impacts affecting the region of interest.

Genetic particle swarm parallel algorithm analysis of optimization arrangement on mistuned blades

NASA Astrophysics Data System (ADS)

Zhao, Tianyu; Yuan, Huiqun; Yang, Wenjun; Sun, Huagang

2017-12-01

This article introduces a method of mistuned parameter identification which consists of static frequency testing of blades, dichotomy and finite element analysis. A lumped parameter model of an engine bladed-disc system is then set up. A bladed arrangement optimization method, namely the genetic particle swarm optimization algorithm, is presented. It consists of a discrete particle swarm optimization and a genetic algorithm. From this, the local and global search ability is introduced. CUDA-based co-evolution particle swarm optimization, using a graphics processing unit, is presented and its performance is analysed. The results show that using optimization results can reduce the amplitude and localization of the forced vibration response of a bladed-disc system, while optimization based on the CUDA framework can improve the computing speed. This method could provide support for engineering applications in terms of effectiveness and efficiency.

2017-12-01

Outstanding characteristics with high T c and H c2 and small anisotropy in iron-based superconductors (IBSs) have triggered the development of superconducting wires and tapes using these novel superconductors. In this short article, developments and present status of round wires of 122-type IBSs are reviewed. By introducing hot-isostatic pressing (HIP) technique, J c in round wires of 122-type IBSs has been improved significantly. Further improvements have been realized by refining the fabrication process of the core material and introducing partial texturing of the wire core. The largest transport J c for round wires at 4.2 K at self-field and 100 kOe are 2.0x105 A/cm2 and 3.8x104 A/cm2, respectively. We also compare the J c characteristics of wires and tapes processed by HIP.

Measuring the Interestingness of Articles in a Limited User Environment

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

Pon, Raymond K.

Search engines, such as Google, assign scores to news articles based on their relevancy to a query. However, not all relevant articles for the query may be interesting to a user. For example, if the article is old or yields little new information, the article would be uninteresting. Relevancy scores do not take into account what makes an article interesting, which varies from user to user. Although methods such as collaborative filtering have been shown to be effective in recommendation systems, in a limited user environment, there are not enough users that would make collaborative filtering effective. A general framework,more » called iScore, is presented for defining and measuring the 'interestingness' of articles, incorporating user-feedback. iScore addresses various aspects of what makes an article interesting, such as topic relevancy, uniqueness, freshness, source reputation, and writing style. It employs various methods to measure these features and uses a classifier operating on these features to recommend articles. The basic iScore configuration is shown to improve recommendation results by as much as 20%. In addition to the basic iScore features, additional features are presented to address the deficiencies of existing feature extractors, such as one that tracks multiple topics, called MTT, and a version of the Rocchio algorithm that learns its parameters online as it processes documents, called eRocchio. The inclusion of both MTT and eRocchio into iScore is shown to improve iScore recommendation results by as much as 3.1% and 5.6%, respectively. Additionally, in TREC11 Adaptive Filter Task, eRocchio is shown to be 10% better than the best filter in the last run of the task. In addition to these two major topic relevancy measures, other features are also introduced that employ language models, phrases, clustering, and changes in topics to improve recommendation results. These additional features are shown to improve recommendation results by iScore by up to 14%. Due to varying reasons that users hold regarding why an article is interesting, an online feature selection method in naive Bayes is also introduced. Online feature selection can improve recommendation results in iScore by up to 18.9%. In summary, iScore in its best configuration can outperform traditional IR techniques by as much as 50.7%. iScore and its components are evaluated in the news recommendation task using three datasets from Yahoo! News, actual users, and Digg. iScore and its components are also evaluated in the TREC Adaptive Filter task using the Reuters RCV1 corpus.« less

2016-05-10

The purpose of the present review is to systematically and critically analyze the available literature regarding the importance, applicability, and practicality of (MRI), computerized tomography (CT) or cone-beam CT (CBCT) image registration for TMJ anatomy and assessment. A systematic search of 4 databases; MEDLINE, EMBASE, EBM reviews and Scopus, was conducted by 2 reviewers. An additional manual search of the bibliography was performed. All articles discussing the magnetic resonance imaging MRI and CT or CBCT image registration for temporomandibular joint (TMJ) visualization or assessment were included. Only 3 articles satisfied the inclusion criteria. All included articles were published within the last 7 years. Two articles described MRI to CT multimodality image registration as a complementary tool to visualize TMJ. Both articles used images of one patient only to introduce the complementary concept of MRI-CT fused image. One article assessed the reliability of using MRI-CBCT registration to evaluate the TMJ disc position and osseous pathology for 10 temporomandibular disorder (TMD) patients. There are very limited studies of MRI-CT/CBCT registration to reach a conclusion regarding its accuracy or clinical use in the temporomandibular joints.

This article presents preliminary findings on how the introduction of patient-generated health data (PGHD) triggers changes during patient-nurse consultations. This article builds on a two-year case study, examining the work practice at a cancer rehabilitation clinic at a Swedish Hospital using PGHD. The study focuses on how nurses' use data, gathered by patients with a mobile phone app, during consultations. The use of PGHD introduce a change in the translation work, the work of turning rich patient descriptions and transform them into data, during the consultation for documentation and clinical decision-making. This change affects precision, questions asked and the use of visualizations as well as the patient-nurse decision making.

History brings together meanings related to earlier periods, being aware of the past as a panorama to reread the present. Madeleine Leininger presented in 1970 an implicit and respectful message to the Nursing Profession when introducing Nursing and Anthropology. Two Worlds to Blend. Implicitly: Nursing you disregard culture. This article shows the absence of the history of anthropology and of nursing within Transcultural Nursing and it includes how education has influenced theoretic, methodological, and comparative approaches giving researchers the responsibility to decide their fundamentals. Berthoud (2001) has inspired the anthropological and historic perspectives of the author, thus universalism, relativism, and comparison are presented.

Incorporation of massage into psychotherapy: an integrative and conjoint approach.

Posadzki, Paul; Parekh-Bhurke, Sheetal

2011-02-01

This article presents the potential integration of psychotherapy and massage when considering the essence of their beneficial effects. 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.

Vagal activity is quadratically related to prosocial traits, prosocial emotions, and observer perceptions of prosociality.

PubMed

2014-12-01

In the present article, we introduce the quadratic vagal activity-prosociality hypothesis, a theoretical framework for understanding the vagus nerve's involvement in prosociality. We argue that vagus nerve activity supports prosocial behavior by regulating physiological systems that enable emotional expression, empathy for others' mental and emotional states, the regulation of one's own distress, and the experience of positive emotions. However, we contend that extremely high levels of vagal activity can be detrimental to prosociality. We present 3 studies providing support for our model, finding consistent evidence of a quadratic relationship between respiratory sinus arrhythmia--the degree to which the vagus nerve modulates the heart rate--and prosociality. Individual differences in vagal activity were quadratically related to prosocial traits (Study 1), prosocial emotions (Study 2), and outside ratings of prosociality by complete strangers (Study 3). Thus, too much or too little vagal activity appears to be detrimental to prosociality. The present article provides the 1st theoretical and empirical account of the nonlinear relationship between vagal activity and prosociality.

Job demands-resources theory: Taking stock and looking forward.

2017-07-01

The job demands-resources (JD-R) model was introduced in the international literature 15 years ago (Demerouti, Bakker, Nachreiner, & Schaufeli, 2001). The model has been applied in thousands of organizations and has inspired hundreds of empirical articles, including 1 of the most downloaded articles of the Journal of Occupational Health Psychology (Bakker, Demerouti, & Euwema, 2005). This article provides evidence for the buffering role of various job resources on the impact of various job demands on burnout. In the present article, we look back on the first 10 years of the JD-R model (2001-2010), and discuss how the model matured into JD-R theory (2011-2016). Moreover, we look at the future of the theory and outline which new issues in JD-R theory are worthwhile of investigation. We also discuss practical applications. It is our hope that JD-R theory will continue to inspire researchers and practitioners who want to promote employee well-being and effective organizational functioning.

2010-03-01

Podcasts and vodcasts (video podcasts) have become popular means of sharing educational information via the Internet. In this article, we introduce another method, an enhanced podcast, which allows images to be displayed with the audio. Bookmarks and URLs may also be imbedded within the presentation. This article describes a step-by-step tutorial for recording and distributing an enhanced podcast using the Macintosh operating system. Enhanced podcasts can also be created on the Windows platform using other software. An example of an enhanced podcast and a demonstration video of all the steps described in this article are available online at web.mac.com/mthapa. An enhanced podcast is an effective method of delivering radiological information via the Internet. Viewing images while simultaneously listening to audio content allows the user to have a richer experience than with a simple podcast. Incorporation of bookmarks and URLs within the presentation will make learning more efficient and interactive. The use of still images rather than video clips equates to a much smaller file size for an enhanced podcast compared to a vodcast, allowing quicker upload and download times.

Toxicological responses to stressors are more complex than the simple one-biological-perturbation to one-adverse-outcome model portrayed by individual adverse outcome pathways (AOPs). Consequently, the AOP framework was designed to facilitate de facto development of AOP networks that can aid in the understanding and prediction of pleiotropic and interactive effects more common to environmentally realistic, complex exposure scenarios. The present study introduces nascent concepts related to the qualitative analysis of AOP networks. First, graph theory-based approaches for identifying important topological features are illustrated using 2 example AOP networks derived from existing AOP descriptions. Second, considerations for identifying the most significant path(s) through an AOP network from either a biological or risk assessment perspective are described. Finally, approaches for identifying interactions among AOPs that may result in additive, synergistic, or antagonistic responses (or previously undefined emergent patterns of response) are introduced. Along with a companion article (part I), these concepts set the stage for the development of tools and case studies that will facilitate more rigorous analysis of AOP networks, and the utility of AOP network-based predictions, for use in research and regulatory decision-making. The present study addresses one of the major themes identified through a Society of Environmental Toxicology and Chemistry Horizon Scanning effort focused on advancing the AOP framework.

XXII European Congress of Medical Informatics (MIe 2009) took place in Sarajevo from August 30th to September 2nd 2009. Assessment of quality of papers presented at MIe 2009 was a process of observation, measurement, comparison and evaluation of the quality of orally presented papers. For this study, and for the first time since EFMI founding (1976) and MIE congresses, the authors introduced a specially created quality assessment form with five relevant paper quality variables (methodological approach, international influence, scientific content, language quality, technical features) which the first author of this article used in peer-review process of papers submitted for publication in the journal Acta Informatica Medica (as Editor-in-Chief for last 18 years). The survey was conducted on the principle of random sampling of participants of MIE 2009 Conference in Sarajevo, where specially trained interviewers (final year students of medicine and engineering at the University of Sarajevo) interviewed 33 session's chairs and 110 participants/listeners of MIE 2009 paper presentations in 33 sessions (of total 40). Data was collected, entered into a specially created database, analyzed and presented. From the total of 150 oral presentations at the MIE 2009, 110 oral presentations were graded by both chairs and participants/ listeners. Grading results were compared and we found that in 60% of cases (66 papers) session chairs gave higher ratings than other participants of the congress. The highest rating was 10, and the lowest 3. Only 3 of the papers received all four grades 10 from the session chairs. The most common grade given by chairs of the session was 8 (26.36%), followed by 7 (20%), 9 (19.32%), 6 (13.18%), 10 and 5 (7.50%), 4 (5%) and 3 (1.14%). Significant differences in quality assessment of papers done by chairs and those done by other participants/listeners are observed. This work should demonstrate the importance of introducing universal (uniform) scale for assessment of articles at conferences that would provide objective and relevant assessment, which has not been the practice. Results obtained using a single standardized scale can be compared to each other and thus improve the quality of the articles and the congress. Future congresses can be organized in this manner and become leading events in certain fields of medical science.

In this article we study the dependence degree of the traded volume of the Dow Jones 30 constituent equities by using a nonextensive generalised form of the Kullback-Leibler information measure. Our results show a slow decay of the dependence degree as a function of the lag. This feature is compatible with the existence of non-linearities in this type time series. In addition, we introduce a dynamical mechanism whose associated stationary probability density function (PDF) presents a good agreement with the empirical results.

Reinforcement Learning in Distributed Domains: Beyond Team Games

NASA Technical Reports Server (NTRS)

Wolpert, David H.; Sill, Joseph; Turner, Kagan

2000-01-01

Distributed search algorithms are crucial in dealing with large optimization problems, particularly when a centralized approach is not only impractical but infeasible. Many machine learning concepts have been applied to search algorithms in order to improve their effectiveness. In this article we present an algorithm that blends Reinforcement Learning (RL) and hill climbing directly, by using the RL signal to guide the exploration step of a hill climbing algorithm. We apply this algorithm to the domain of a constellations of communication satellites where the goal is to minimize the loss of importance weighted data. We introduce the concept of 'ghost' traffic, where correctly setting this traffic induces the satellites to act to optimize the world utility. Our results indicated that the bi-utility search introduced in this paper outperforms both traditional hill climbing algorithms and distributed RL approaches such as team games.

Kozak, Leila; Boynton, Lorin; Bentley, Jacob; Bezy, Emma

2010-06-01

A growing body of research suggests that religion and spirituality may have a positive effect on mental and physical health. Medical schools have been increasingly offering courses in spirituality and health, particularly about the multi-cultural dimensions of religion and spirituality. There is a trend towards integrating the teaching of cross-cultural issues related to spirituality and religion into medical education. This trend is particularly evident in the field of psychiatry, where an increasing number of residency programmes are developing curriculum in this area. This article describes a specific curriculum in spirituality, religion and culture that was introduced in 2003 at the University of Washington Psychiatry Residency Program in Seattle, Washington. Reflections about the present and future of subject areas such as spirituality and religion in medical education and psychiatry residency are discussed.

At the Limit: Introducing Energy with Human Senses

NASA Astrophysics Data System (ADS)

Stinken, Lisa; Heusler, Stefan; Carmesin, Hans-Otto

2016-12-01

Energy belongs to the core ideas of the physics curriculum. But at the same time, energy is one of the most complex topics in science education since it occurs in multiple ways, such as motion, sound, light, and thermal energy. It can neither be destroyed nor created, but only converted. Due to the variety of relevant scales and abstractness of the term energy, the question arises how to introduce energy at the introductory physics level. The aim of this article is to demonstrate how the concept of energy can become meaningful in the context of the human senses. Three simple experiments to investigate the minimal amount of energy that is required to generate a sensory perception are presented. In this way students can learn that even different sensory perceptions can be compared by using energy as the unifying concept.

Privacy Preserving Association Rule Mining Revisited: Privacy Enhancement and Resources Efficiency

NASA Astrophysics Data System (ADS)

Mohaisen, Abedelaziz; Jho, Nam-Su; Hong, Dowon; Nyang, Daehun

Privacy preserving association rule mining algorithms have been designed for discovering the relations between variables in data while maintaining the data privacy. In this article we revise one of the recently introduced schemes for association rule mining using fake transactions (FS). In particular, our analysis shows that the FS scheme has exhaustive storage and high computation requirements for guaranteeing a reasonable level of privacy. We introduce a realistic definition of privacy that benefits from the average case privacy and motivates the study of a weakness in the structure of FS by fake transactions filtering. In order to overcome this problem, we improve the FS scheme by presenting a hybrid scheme that considers both privacy and resources as two concurrent guidelines. Analytical and empirical results show the efficiency and applicability of our proposed scheme.

Delaying Mobility Disability in People With Parkinson Disease Using a Sensorimotor Agility Exercise Program

PubMed Central

King, Laurie A; Horak, Fay B

2009-01-01

This article introduces a new framework for therapists to develop an exercise program to delay mobility disability in people with Parkinson disease (PD). Mobility, or the ability to efficiently navigate and function in a variety of environments, requires balance, agility, and flexibility, all of which are affected by PD. This article summarizes recent research identifying how constraints on mobility specific to PD, such as rigidity, bradykinesia, freezing, poor sensory integration, inflexible program selection, and impaired cognitive processing, limit mobility in people with PD. Based on these constraints, a conceptual framework for exercises to maintain and improve mobility is presented. An example of a constraint-focused agility exercise program, incorporating movement principles from tai chi, kayaking, boxing, lunges, agility training, and Pilates exercises, is presented. This new constraint-focused agility exercise program is based on a strong scientific framework and includes progressive levels of sensorimotor, resistance, and coordination challenges that can be customized for each patient while maintaining fidelity. Principles for improving mobility presented here can be incorporated into an ongoing or long-term exercise program for people with PD. PMID:19228832

2018-05-01

In a pair of linked articles (called Papers I and II, respectively), we apply the concept of Lagrangian Coherent Structures (LCSs) borrowed from the study of dynamical systems to magnetic field configurations in order to separate regions where field lines have a different kind of behaviour. In the present article, Paper I, after recalling the definition and the properties of the LCSs, we show how this conceptual framework can be applied to the study of particle transport in a magnetized plasma. Furthermore, we introduce a simplified model that allows us to consider explicitly the case where the magnetic configuration evolves in time on time scales comparable to the particle transit time through the configuration. In contrast with previous works on this topic, this analysis requires that a system that is aperiodic in time be investigated.

Evaluation reports increasingly document the degree of program implementation, particularly the extent to which programs adhere to prescribed steps and procedures. Many reports are cursory, however, and few, if any, fully portray the long and winding path taken when developing evaluation instruments, particularly observation instruments. In this article, we describe the development of an observational method for evaluating the degree to which K-12 inquiry science programs are implemented, including the many steps and decisions that occurred during the development, and present evidence for the reliability and validity of the data that we collected with the instrument. The article introduces a method for measuring the adherence of inquiry science implementation and gives evaluators a full picture of what they might expect when developing observation instruments for assessing the degree of program implementation.

The Cognitive Neuroscience of Sign Language: Engaging Undergraduate Students' Critical Thinking Skills Using the Primary Literature.

PubMed

Stevens, Courtney

2015-01-01

This article presents a modular activity on the neurobiology of sign language that engages undergraduate students in reading and analyzing the primary functional magnetic resonance imaging (fMRI) literature. Drawing on a seed empirical article and subsequently published critique and rebuttal, students are introduced to a scientific debate concerning the functional significance of right-hemisphere recruitment observed in some fMRI studies of sign language processing. The activity requires minimal background knowledge and is not designed to provide students with a specific conclusion regarding the debate. Instead, the activity and set of articles allow students to consider key issues in experimental design and analysis of the primary literature, including critical thinking regarding the cognitive subtractions used in blocked-design fMRI studies, as well as possible confounds in comparing results across different experimental tasks. By presenting articles representing different perspectives, each cogently argued by leading scientists, the readings and activity also model the type of debate and dialogue critical to science, but often invisible to undergraduate science students. Student self-report data indicate that undergraduates find the readings interesting and that the activity enhances their ability to read and interpret primary fMRI articles, including evaluating research design and considering alternate explanations of study results. As a stand-alone activity completed primarily in one 60-minute class block, the activity can be easily incorporated into existing courses, providing students with an introduction both to the analysis of empirical fMRI articles and to the role of debate and critique in the field of neuroscience.

The concept of being at risk for psychosis has been introduced both for adults and children and adolescents, but fewer studies have been conducted in the latter population. The aim of this study is to systematically review the articles associated with clinical description, interventions, outcome and other areas in children and adolescents at risk for psychosis. We searched in MEDLINE/PubMed and PsycINFO databases for articles published up to 30/06/16. Reviewed articles were prospective studies; written in English; original articles with Clinical High Risk (CHR) for psychosis samples; and mean age of samples younger than 18 years. From 103 studies initially selected, 48 met inclusion criteria and were systematically reviewed. Studies show that CHR children and adolescents present several clinical characteristics at baseline, with most attenuated positive-symptom inclusion criteria observed, reporting mostly perceptual abnormalities and suspiciousness, and presenting comorbid conditions such as depressive and anxiety disorders. CHR children and adolescents show lower general intelligence and no structural brain changes compared with controls. Original articles reviewed show rates of conversion to psychosis between 17 and 20% at 1 year follow-up and between 7 and 21% at 2 years. While 36% of patients recovered from their CHR status at 6-year follow-up, 40% still met CHR criteria. Studies in children and adolescents with CHR were conducted with different methodologies, assessments tools and small samples. It is important to conduct studies on psychopharmacological and psychological treatment, as well as replication of the few studies found.

Fluid Dynamics of Human Phonation and Speech

Mittal, Rajat; Erath, Byron D.; Plesniak, Michael W.

2013-01-01

This article presents a review of the fluid dynamics, flow-structure interactions, and acoustics associated with human phonation and speech. Our voice is produced through the process of phonation in the larynx, and an improved understanding of the underlying physics of this process is essential to advancing the treatment of voice disorders. Insights into the physics of phonation and speech can also contribute to improved vocal training and the development of new speech compression and synthesis schemes. This article introduces the key biomechanical features of the laryngeal physiology, reviews the basic principles of voice production, and summarizes the progress made over the past half-century in understanding the flow physics of phonation and speech. Laryngeal pathologies, which significantly enhance the complexity of phonatory dynamics, are discussed. After a thorough examination of the state of the art in computational modeling and experimental investigations of phonatory biomechanics, we present a synopsis of the pacing issues in this arena and an outlook for research in this fascinating subject.

Effects of external magnetic fields and Rashba spin-orbit coupling on spin conductance in graphene

NASA Astrophysics Data System (ADS)

Shirkani, H.; Amiri, F.; Golshan, M. M.

2013-12-01

The present article is concerned with spin conductance in graphene (SCG) when both the application of an external magnetic field and Rashba spin-orbit coupling (RSOC) are taken into account. Introducing a Casimir operator, we analyze the structure of total Hamiltonian and demonstrate how the matrix elements along with the summations involved in the suitably adopted Kubo’s formula, may be analytically calculated. From the results so-obtained one finds that, in addition to discrete and symmetric behavior of SCG against the external field, it exhibits large peaks as high as six times that in ordinary two dimensional electron gases. Moreover, it is shown that for any Fermi energy the SCG asymptotically approaches a value three times larger than the standard unit of (e/4π), for large magnetic fields. Effects of the magnetic field, RSOC and Fermi energy on the characteristics of SCG are also discussed. The material presented in this article thus provides novel means of controlling the SCG by external agents.

Vehicle systems: coupled and interactive dynamics analysis

NASA Astrophysics Data System (ADS)

Vantsevich, Vladimir V.

2014-11-01

This article formulates a new direction in vehicle dynamics, described as coupled and interactive vehicle system dynamics. Formalised procedures and analysis of case studies are presented. An analytical consideration, which explains the physics of coupled system dynamics and its consequences for dynamics of a vehicle, is given for several sets of systems including: (i) driveline and suspension of a 6×6 truck, (ii) a brake mechanism and a limited slip differential of a drive axle and (iii) a 4×4 vehicle steering system and driveline system. The article introduces a formal procedure to turn coupled system dynamics into interactive dynamics of systems. A new research direction in interactive dynamics of an active steering and a hybrid-electric power transmitting unit is presented and analysed to control power distribution between the drive axles of a 4×4 vehicle. A control strategy integrates energy efficiency and lateral dynamics by decoupling dynamics of the two systems thus forming their interactive dynamics.

The advent of the digital pathology has introduced new avenues of diagnostic medicine. Among them, crowdsourcing has attracted researchers' attention in the recent years, allowing them to engage thousands of untrained individuals in research and diagnosis. While there exist several articles in this regard, prior works have not collectively documented them. We, therefore, aim to review the applications of crowdsourcing in human pathology in a semi-systematic manner. We first, introduce a novel method to do a systematic search of the literature. Utilizing this method, we, then, collect hundreds of articles and screen them against a predefined set of criteria. Furthermore, we crowdsource part of the screening process, to examine another potential application of crowdsourcing. Finally, we review the selected articles and characterize the prior uses of crowdsourcing in pathology.

2012-01-01

Models--mathematical frameworks that facilitate estimation of the consequences of health care decisions--have become essential tools for health technology assessment. Evolution of the methods since the first ISPOR Modeling Task Force reported in 2003 has led to a new Task Force, jointly convened with the Society for Medical Decision Making, and this series of seven articles presents the updated recommendations for best practices in conceptualizing models; implementing state-transition approaches, discrete event simulations, or dynamic transmission models; and dealing with uncertainty and validating and reporting models transparently. This overview article introduces the work of the Task Force, provides all the recommendations, and discusses some quandaries that require further elucidation. The audience for these articles includes those who build models, stakeholders who utilize their results, and, indeed, anyone concerned with the use of models to support decision making.

Personality and self-regulation: trait and information-processing perspectives.

PubMed

Hoyle, Rick H

2006-12-01

This article introduces the special issue of Journal of Personality on personality and self-regulation. The goal of the issue is to illustrate and inspire research that integrates personality and process-oriented accounts of self-regulation. The article begins by discussing the trait perspective on self-regulation--distinguishing between temperament and personality accounts--and the information-processing perspective. Three approaches to integrating these perspectives are then presented. These range from methodological approaches, in which constructs representing the two perspectives are examined in integrated statistical models, to conceptual approaches, in which the two perspectives are unified in a holistic theoretical model of self-regulation. The article concludes with an overview of the special issue contributions, which are organized in four sections: broad, integrative models of personality and self-regulation; models that examine the developmental origins of self-regulation and self-regulatory styles; focused programs of research that concern specific aspects or applications of self-regulation; and strategies for increasing the efficiency and effectiveness of self-regulation.

Dunkle, Jennifer; Flynn, Perry

2012-05-01

The Common Core State Standards initiative within public school education is designed to provide uniform guidelines for academic standards, including more explicit language targets. Speech-language pathologists (SLPs) are highly qualified language experts who may find new leadership roles within their clinical practice using the Common Core Standards. However, determining its usage by SLPs in clinical practice needs to be examined. This article seeks to discover the social context of organizations and organizational change in relation to clinical practice. Specifically, this article presents the diffusion of innovations theory to explain how initiatives move from ideas to institutionalization and the importance of social context in which these initiatives are introduced. Next, the values of both SLPs and organizations will be discussed. Finally, this article provides information on how to affect organizational change through the value of an affirmative, socially based theoretical perspective and methodology, appreciative inquiry.

Increasing the odds: applying emergentist theory in language intervention.

PubMed

Poll, Gerard H

2011-10-01

This review introduces emergentism, which is a leading theory of language development that states that language ability is the product of interactions between the child's language environment and his or her learning capabilities. The review suggests ways in which emergentism provides a theoretical rationale for interventions that are designed to address developmental language delays in young children. A review of selected literature on emergentist theory and research is presented, with a focus on the acquisition of early morphology and syntax. A significant method for developing and testing emergentist theory, connectionist modeling, is described. Key themes from both connectionist and behavioral studies are summarized and applied with specific examples to language intervention techniques. A case study is presented to integrate elements of emergentism with language intervention. Evaluating the theoretical foundation for language interventions is an important step in evidence-based practice. This article introduces three themes in the emergentist literature that have implications for language intervention: (a) sufficiency of language input, (b) active engagement of the child with the input, and (c) factors that increase the odds for correctly mapping language form to meaning. Evidence supporting the importance of these factors in effective language intervention is presented, along with limitations in that evidence.

DNA biosensors that reason.

PubMed

Sainz de Murieta, Iñaki; Rodríguez-Patón, Alfonso

2012-08-01

Despite the many designs of devices operating with the DNA strand displacement, surprisingly none is explicitly devoted to the implementation of logical deductions. The present article introduces a new model of biosensor device that uses nucleic acid strands to encode simple rules such as "IF DNA_strand(1) is present THEN disease(A)" or "IF DNA_strand(1) AND DNA_strand(2) are present THEN disease(B)". Taking advantage of the strand displacement operation, our model makes these simple rules interact with input signals (either DNA or any type of RNA) to generate an output signal (in the form of nucleotide strands). This output signal represents a diagnosis, which either can be measured using FRET techniques, cascaded as the input of another logical deduction with different rules, or even be a drug that is administered in response to a set of symptoms. The encoding introduces an implicit error cancellation mechanism, which increases the system scalability enabling longer inference cascades with a bounded and controllable signal-noise relation. It also allows the same rule to be used in forward inference or backward inference, providing the option of validly outputting negated propositions (e.g. "diagnosis A excluded"). The models presented in this paper can be used to implement smart logical DNA devices that perform genetic diagnosis in vitro. Copyright © 2012 Elsevier Ireland Ltd. All rights reserved.

A seismic data compression system using subband coding

NASA Technical Reports Server (NTRS)

Kiely, A. B.; Pollara, F.

1995-01-01

This article presents a study of seismic data compression techniques and a compression algorithm based on subband coding. The algorithm includes three stages: a decorrelation stage, a quantization stage that introduces a controlled amount of distortion to allow for high compression ratios, and a lossless entropy coding stage based on a simple but efficient arithmetic coding method. Subband coding methods are particularly suited to the decorrelation of nonstationary processes such as seismic events. Adaptivity to the nonstationary behavior of the waveform is achieved by dividing the data into separate blocks that are encoded separately with an adaptive arithmetic encoder. This is done with high efficiency due to the low overhead introduced by the arithmetic encoder in specifying its parameters. The technique could be used as a progressive transmission system, where successive refinements of the data can be requested by the user. This allows seismologists to first examine a coarse version of waveforms with minimal usage of the channel and then decide where refinements are required. Rate-distortion performance results are presented and comparisons are made with two block transform methods.

Evolutionary Developmental Robotics: Improving Morphology and Control of Physical Robots.

PubMed

Vujovic, Vuk; Rosendo, Andre; Brodbeck, Luzius; Iida, Fumiya

2017-01-01

Evolutionary algorithms have previously been applied to the design of morphology and control of robots. The design space for such tasks can be very complex, which can prevent evolution from efficiently discovering fit solutions. In this article we introduce an evolutionary-developmental (evo-devo) experiment with real-world robots. It allows robots to grow their leg size to simulate ontogenetic morphological changes, and this is the first time that such an experiment has been performed in the physical world. To test diverse robot morphologies, robot legs of variable shapes were generated during the evolutionary process and autonomously built using additive fabrication. We present two cases with evo-devo experiments and one with evolution, and we hypothesize that the addition of a developmental stage can be used within robotics to improve performance. Moreover, our results show that a nonlinear system-environment interaction exists, which explains the nontrivial locomotion patterns observed. In the future, robots will be present in our daily lives, and this work introduces for the first time physical robots that evolve and grow while interacting with the environment.

Cationic liposomes are lipid-bilayer vesicles with a positive surface charge that have re-emerged as a promising new adjuvant technology. Although there is some evidence that cationic liposomes themselves can improve the immune response against coadministered vaccine antigens, their main functions are to protect the antigens from clearance in the body and deliver the antigens to professional antigen-presenting cells. In addition, cationic liposomes can be used to introduce immunomodulators to enhance and modulate the immune response in a desirable direction and, thereby, represent an efficient tool when designing tailor-made adjuvants for specific disease targets. In this article we review the recent progress on cationic liposomes as vehicles, enhancing the effect of immunomodulators and the presentation of vaccine antigens.

Vazquez, Miguel; Krallinger, Martin; Leitner, Florian; Valencia, Alfonso

2011-06-01

Providing prior knowledge about biological properties of chemicals, such as kinetic values, protein targets, or toxic effects, can facilitate many aspects of drug development. Chemical information is rapidly accumulating in all sorts of free text documents like patents, industry reports, or scientific articles, which has motivated the development of specifically tailored text mining applications. Despite the potential gains, chemical text mining still faces significant challenges. One of the most salient is the recognition of chemical entities mentioned in text. To help practitioners contribute to this area, a good portion of this review is devoted to this issue, and presents the basic concepts and principles underlying the main strategies. The technical details are introduced and accompanied by relevant bibliographic references. Other tasks discussed are retrieving relevant articles, identifying relationships between chemicals and other entities, or determining the chemical structures of chemicals mentioned in text. This review also introduces a number of published applications that can be used to build pipelines in topics like drug side effects, toxicity, and protein-disease-compound network analysis. We conclude the review with an outlook on how we expect the field to evolve, discussing its possibilities and its current limitations. Copyright © 2011 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

Restless legs syndrome/Willis Ekbom disease: evaluation and treatment.

PubMed

Allen, Richard P

2014-04-01

Restless legs syndrome/Willis Ekbom disease (RLS/WED) has been recognized as a significant medical disorder since the 17th century. It was studied mostly in the last 50 years in relation to increasing interest in sleep medicine and health-related quality of life. This led to recognition that the disease is not well characterized as restless feelings in the legs. These symptoms are reported in many situations, but the subjective experience of RLS/WED patients differs from that experienced by others. Thus a new name has been introduced that avoids problems of symptom definition of a disease by naming it after those who first characterized it, i.e. 'Willis Ekbom disease'. This article emphasizes the importance of RLS/WED for psychiatry. The disease carries significant increased risk for depression and anxiety disorders. Treatment requires consideration of these co-morbid disorders. RLS/WED can exacerbate or even engender psychiatric disease, so treatment of psychiatric disease should also include consideration of RLS/WED. The need for attention to RLS/WED is particularly significant for depression. Most anti-depressants exacerbate or can even engender RLS/WED. Thus this article seeks to introduce RLS/WED in relation to psychiatric practice. It presents the RLS/WED disease, its overlap with psychiatry and the current treatment options.

Relational responsibilities in responsive evaluation.

PubMed

Visse, Merel; Abma, Tineke A; Widdershoven, Guy A M

2012-02-01

This article explores how we can enhance our understanding of the moral responsibilities in daily, plural practices of responsive evaluation. It introduces an interpretive framework for understanding the moral aspects of evaluation practice. The framework supports responsive evaluators to better understand and handle their moral responsibilities. A case is introduced to illustrate our argument. Responsive evaluation contributes to the design and implementation of policy by working with stakeholders and coordinating the evaluation process as a relationally responsible practice. Responsive evaluation entails a democratic process in which the evaluator fosters and enters a partnership with stakeholders. The responsibilities of an evaluator generally involve issues such as 'confidentiality', 'accountability' and 'privacy'. The responsive evaluator has specific responsibilities, for example to include stakeholders and vulnerable groups and to foster an ongoing dialogue. In addition, responsive evaluation involves a relational responsibility, which becomes present in daily situations in which stakeholders express expectations and voice demands. In our everyday work as evaluators, it is difficult to respond to all these demands at the same time. In addition, this article demonstrates that novice evaluators experience challenges concerning over- and underidenfitication with stakeholders. Guidelines and quality criteria on how to act are helpful, but need interpretation and application to the unique situation at hand. Copyright © 2011 Elsevier Ltd. All rights reserved.

Information technology has become heavily embedded in business operations. As business needs change over time, IT applications are expected to continue providing required support. Whether the existing IT applications are still fit for the business purpose they were intended or new IT applications should be introduced is a strategic decision for business, IT and business-aligned IT. In this article, we present a method that aims to analyse business functions and IT roles and to evaluate business-aligned IT from both social and technical perspectives. The method introduces a set of techniques that systematically supports the evaluation of the existing IT applications in relation to their technical capabilities for maximising business value. Furthermore, we discuss the evaluation process and results that are illustrated and validated through a real-life case study of a UK borough council and followed by discussion on implications for researchers and practitioners.

Influence of safety measures on the risks of transporting dangerous goods through road tunnels.

PubMed

Saccomanno, Frank; Haastrup, Palle

2002-12-01

Quantitative risk assessment (QRA) models are used to estimate the risks of transporting dangerous goods and to assess the merits of introducing alternative risk reduction measures for different transportation scenarios and assumptions. A comprehensive QRA model recently was developed in Europe for application to road tunnels. This model can assess the merits of a limited number of "native safety measures." In this article, we introduce a procedure for extending its scope to include the treatment of a number of important "nonnative safety measures" of interest to tunnel operators and decisionmakers. Nonnative safety measures were not included in the original model specification. The suggested procedure makes use of expert judgment and Monte Carlo simulation methods to model uncertainty in the revised risk estimates. The results of a case study application are presented that involve the risks of transporting a given volume of flammable liquid through a 10-km road tunnel.

Nowadays, superconductors serve in numerous applications, from high-field magnets to ultrasensitive detectors of radiation. Mesoscopic superconducting devices, referring to those with nanoscale dimensions, are in a special position as they are easily driven out of equilibrium under typical operating conditions. The out-of-equilibrium superconductors are characterized by non-equilibrium quasiparticles. These extra excitations can compromise the performance of mesoscopic devices by introducing, for example, leakage currents or decreased coherence time in quantum devices. By applying an external magnetic field, one can conveniently suppress or redistribute the population of excess quasiparticles. In this article, we present an experimental demonstration and a theoretical analysis of such effective control of quasiparticles, resulting in electron cooling both in the Meissner and vortex states of a mesoscopic superconductor. We introduce a theoretical model of quasiparticle dynamics, which is in quantitative agreement with the experimental data.

There have been few attempts to identify classic papers within the hand surgery literature. This study used citation analysis to identify and characterize the top 50 highly cited hand surgery articles published in six peer-reviewed journals. The 50 most highly cited hand surgery articles were identified in the Journal of Bone and Joint Surgery (JBJS) American, JBJS British, Plastic and Reconstructive Surgery, Journal of Hand Surgery (JHS) American, JHS British/European, and Hand. Articles were evaluated for citations per year, surgical/anatomical topic, and type of study. Clinical studies were further sub-categorized by level of evidence. The distribution of topics was compared with all indexed hand surgery articles. The educational relevance was assessed via comparison with lists of "classic" papers. The most common subjects were distal radius fracture, carpal tunnel syndrome, and flexor tendon repair. There was moderate correlation between the distribution of these topics and all indexed hand surgery articles (rho = 0.71). There were 31 clinical studies, of which 16 were therapeutic, ten were prognostic, and five were diagnostic. These articles assessed the outcomes of an intervention, described an anatomical/functional observation, introduced an innovation, presented a discovery/classification, or validated a questionnaire. There were only three randomized trials. Using citations per year to control for the influence of time since publication, 36 articles were consistently highly cited. Twenty-three articles were on Stern's Selected Readings in Hand Surgery, considered important in education. The top 50 highly cited articles in hand surgery reflect the most common clinical, scientific, and educational efforts of the field.

2017-12-01

This introduction to the special issue presents an overview of the wide range of results produced during the European Union project Arctic Climate Change, Economy and Society (ACCESS). This project assessed the main impacts of climate change on Arctic Ocean's geophysical variables and how these impending changes could be expected to impact directly and indirectly on socio-economic activities like transportation, marine sea food production and resource exploitation. Related governance issues were examined. These results were used to develop several management tools that can live on beyond ACCESS. In this article, we synthesize most of the project results in the form of tentative responses to questions raised during the project. By doing so, we put the findings of the project in a broader perspective and introduce the contributions made in the different articles published in this special issue.

New robust statistical procedures for the polytomous logistic regression models.

PubMed

Castilla, Elena; Ghosh, Abhik; Martin, Nirian; Pardo, Leandro

2018-05-17

This article derives a new family of estimators, namely the minimum density power divergence estimators, as a robust generalization of the maximum likelihood estimator for the polytomous logistic regression model. Based on these estimators, a family of Wald-type test statistics for linear hypotheses is introduced. Robustness properties of both the proposed estimators and the test statistics are theoretically studied through the classical influence function analysis. Appropriate real life examples are presented to justify the requirement of suitable robust statistical procedures in place of the likelihood based inference for the polytomous logistic regression model. The validity of the theoretical results established in the article are further confirmed empirically through suitable simulation studies. Finally, an approach for the data-driven selection of the robustness tuning parameter is proposed with empirical justifications. © 2018, The International Biometric Society.

Comparison of concepts in easy-to-use methods for MSD risk assessment.

2014-05-01

This article presents a comparative analysis of easy-to-use methods for assessing musculoskeletal load and the risk for developing musculoskeletal disorders. In all such methods, assessment of load consists in defining input data, the procedure and the system of assessment. This article shows what assessment steps the methods have in common; it also shows how those methods differ in each step. In addition, the methods are grouped according to their characteristic features. The conclusion is that the concepts of assessing risk in different methods can be used to develop solutions leading to a comprehensive method appropriate for all work tasks and all parts of the body. However, studies are necessary to verify the accepted premises and to introduce some standardization that would make consolidation possible. Copyright © 2013 Elsevier Ltd and The Ergonomics Society.

Jang, Jung Eun

2016-06-01

The purpose of this article is to present a sketch of a new image of pastoral care and counseling, which reflects the psychoanalytic understanding of the interacting transference and countertransference matrix, along with a process view of God in a mutually influencing relationship with creatures. A more effective approach in pastoral care and counseling can be conceptualized as the interactive play in which pastoral caregivers and receivers co-create a therapeutic relationship with their own past experiences and their creative capabilities. The interactive play is a concept of describing the mutually influencing relationship in the transference and countertransference interchange. The article introduces the concept of a persuasive God as a new image of pastoral care and counseling which includes aspects of the mutually interacting process in play. © The Author(s) 2016.

Discrimination of dynamical system models for biological and chemical processes.

PubMed

Lorenz, Sönke; Diederichs, Elmar; Telgmann, Regina; Schütte, Christof

2007-06-01

In technical chemistry, systems biology and biotechnology, the construction of predictive models has become an essential step in process design and product optimization. Accurate modelling of the reactions requires detailed knowledge about the processes involved. However, when concerned with the development of new products and production techniques for example, this knowledge often is not available due to the lack of experimental data. Thus, when one has to work with a selection of proposed models, the main tasks of early development is to discriminate these models. In this article, a new statistical approach to model discrimination is described that ranks models wrt. the probability with which they reproduce the given data. The article introduces the new approach, discusses its statistical background, presents numerical techniques for its implementation and illustrates the application to examples from biokinetics.

Partially pre-calculated weights for the backpropagation learning regime and high accuracy function mapping using continuous input RAM-based sigma-pi nets.

PubMed

Neville, R S; Stonham, T J; Glover, R J

2000-01-01

In this article we present a methodology that partially pre-calculates the weight updates of the backpropagation learning regime and obtains high accuracy function mapping. The paper shows how to implement neural units in a digital formulation which enables the weights to be quantised to 8-bits and the activations to 9-bits. A novel methodology is introduced to enable the accuracy of sigma-pi units to be increased by expanding their internal state space. We, also, introduce a novel means of implementing bit-streams in ring memories instead of utilising shift registers. The investigation utilises digital "Higher Order" sigma-pi nodes and studies continuous input RAM-based sigma-pi units. The units are trained with the backpropagation learning regime to learn functions to a high accuracy. The neural model is the sigma-pi units which can be implemented in digital microelectronic technology. The ability to perform tasks that require the input of real-valued information, is one of the central requirements of any cognitive system that utilises artificial neural network methodologies. In this article we present recent research which investigates a technique that can be used for mapping accurate real-valued functions to RAM-nets. One of our goals was to achieve accuracies of better than 1% for target output functions in the range Y epsilon [0,1], this is equivalent to an average Mean Square Error (MSE) over all training vectors of 0.0001 or an error modulus of 0.01. We present a development of the sigma-pi node which enables the provision of high accuracy outputs. The sigma-pi neural model was initially developed by Gurney (Learning in nets of structured hypercubes. PhD Thesis, Department of Electrical Engineering, Brunel University, Middlessex, UK, 1989; available as Technical Memo CN/R/144). Gurney's neuron models, the Time Integration Node (TIN), utilises an activation that was derived from a bit-stream. In this article we present a new methodology for storing sigma-pi node's activations as single values which are averages. In the course of the article we state what we define as a real number; how we represent real numbers and input of continuous values in our neural system. We show how to utilise the bounded quantised site-values (weights) of sigma-pi nodes to make training of these neurocomputing systems simple, using pre-calculated look-up tables to train the nets. In order to meet our accuracy goal, we introduce a means of increasing the bandwidth capability of sigma-pi units by expanding their internal state-space. In our implementation we utilise bit-streams when we calculate the real-valued outputs of the net. To simplify the hardware implementation of bit-streams we present a method of mapping them to RAM-based hardware using 'ring memories'. Finally, we study the sigma-pi units' ability to generalise once they are trained to map real-valued, high accuracy, continuous functions. We use sigma-pi units as they have been shown to have shorter training times than their analogue counterparts and can also overcome some of the drawbacks of semi-linear units (Gurney, 1992. Neural Networks, 5, 289-303).

Navigating the complexities of qualitative comparative analysis: case numbers, necessity relations, and model ambiguities.

PubMed

Thiem, Alrik

2014-12-01

In recent years, the method of Qualitative Comparative Analysis (QCA) has been enjoying increasing levels of popularity in evaluation and directly neighboring fields. Its holistic approach to causal data analysis resonates with researchers whose theories posit complex conjunctions of conditions and events. However, due to QCA's relative immaturity, some of its technicalities and objectives have not yet been well understood. In this article, I seek to raise awareness of six pitfalls of employing QCA with regard to the following three central aspects: case numbers, necessity relations, and model ambiguities. Most importantly, I argue that case numbers are irrelevant to the methodological choice of QCA or any of its variants, that necessity is not as simple a concept as it has been suggested by many methodologists, and that doubt must be cast on the determinacy of virtually all results presented in past QCA research. By means of empirical examples from published articles, I explain the background of these pitfalls and introduce appropriate procedures, partly with reference to current software, that help avoid them. QCA carries great potential for scholars in evaluation and directly neighboring areas interested in the analysis of complex dependencies in configurational data. If users beware of the pitfalls introduced in this article, and if they avoid mechanistic adherence to doubtful "standards of good practice" at this stage of development, then research with QCA will gain in quality, as a result of which a more solid foundation for cumulative knowledge generation and well-informed policy decisions will also be created. © The Author(s) 2014.

Processes of social flourishing and their liminal collapse: elements to a genealogy of globalization.

PubMed

Szakolczai, Arpad

2016-09-01

This article aims at exploring a long-term historical perspective on which contemporary globalization can be more meaningfully situated. A central problem with established approaches to globalization is that they are even more presentist than the literature on modernization was. Presentism not only means the ignoring of history, but also the unreflective application to history of concepts taken from the study of the modern world. In contrast, it is argued that contemporary globalization is not a unique development, but rather is a concrete case of a historical type. Taking as its point of departure the spirit, rather than the word, of Max Weber, this article extends the scope of sociological investigation into archaeological evidence. Having a genealogical design and introducing the concept of 'liminality', the article approaches the modern process of globalization through reconstructing the internal dynamics of another type of historical change called 'social flourishing'. Taking up the Weberian approach continued by Eisenstadt in his writings on 'axial age', it moves away from situations of crisis as reference point, shifting attention to periods of revival by introducing the term 'epiphany'. Through the case of early Mesopotamia, it shows how social flourishing can be transmogrified into globalizing growth, gaining a new perspective concerning the kind of 'animating spirit' that might have driven the shift from Renaissance to Reformation, the rise of modern colonialism, or contemporary globalization. More generally, it will retrieve the long-term historical background of the axial age and demonstrate the usefulness and importance of archaeological evidence for sociology. © London School of Economics and Political Science 2016.

Plasma-surface interaction in the context of ITER.

PubMed

Kleyn, A W; Lopes Cardozo, N J; Samm, U

2006-04-21

The decreasing availability of energy and concern about climate change necessitate the development of novel sustainable energy sources. Fusion energy is such a source. Although it will take several decades to develop it into routinely operated power sources, the ultimate potential of fusion energy is very high and badly needed. A major step forward in the development of fusion energy is the decision to construct the experimental test reactor ITER. ITER will stimulate research in many areas of science. This article serves as an introduction to some of those areas. In particular, we discuss research opportunities in the context of plasma-surface interactions. The fusion plasma, with a typical temperature of 10 keV, has to be brought into contact with a physical wall in order to remove the helium produced and drain the excess energy in the fusion plasma. The fusion plasma is far too hot to be brought into direct contact with a physical wall. It would degrade the wall and the debris from the wall would extinguish the plasma. Therefore, schemes are developed to cool down the plasma locally before it impacts on a physical surface. The resulting plasma-surface interaction in ITER is facing several challenges including surface erosion, material redeposition and tritium retention. In this article we introduce how the plasma-surface interaction relevant for ITER can be studied in small scale experiments. The various requirements for such experiments are introduced and examples of present and future experiments will be given. The emphasis in this article will be on the experimental studies of plasma-surface interactions.

Kernels, Degrees of Freedom, and Power Properties of Quadratic Distance Goodness-of-Fit Tests

PubMed Central

Lindsay, Bruce G.; Markatou, Marianthi; Ray, Surajit

2014-01-01

In this article, we study the power properties of quadratic-distance-based goodness-of-fit tests. First, we introduce the concept of a root kernel and discuss the considerations that enter the selection of this kernel. We derive an easy to use normal approximation to the power of quadratic distance goodness-of-fit tests and base the construction of a noncentrality index, an analogue of the traditional noncentrality parameter, on it. This leads to a method akin to the Neyman-Pearson lemma for constructing optimal kernels for specific alternatives. We then introduce a midpower analysis as a device for choosing optimal degrees of freedom for a family of alternatives of interest. Finally, we introduce a new diffusion kernel, called the Pearson-normal kernel, and study the extent to which the normal approximation to the power of tests based on this kernel is valid. Supplementary materials for this article are available online. PMID:24764609

Review of Diagnosis-Related Group-Based Financing of Hospital Care

PubMed Central

Kocic, Sanja; Jakovljevic, Mihajlo

2016-01-01

Since the 1990s, diagnosis-related group (DRG)-based payment systems were gradually introduced in many countries. The main design characteristics of a DRG-based payment system are an exhaustive patient case classification system (ie, the system of diagnosis-related groupings) and the payment formula, which is based on the base rate multiplied by a relative cost weight specific for each DRG. Cases within the same DRG code group are expected to undergo similar clinical evolution. Consecutively, they should incur the costs of diagnostics and treatment within a predefined scale. Such predictability was proven in a number of cost-of-illness studies conducted on major prosperity diseases alongside clinical trials on efficiency. This was the case with risky pregnancies, chronic obstructive pulmonary disease, diabetes, depression, alcohol addiction, hepatitis, and cancer. This article presents experience of introduced DRG-based payments in countries of western and eastern Europe, Scandinavia, United States, Canada, and Australia. This article presents the results of few selected reviews and systematic reviews of the following evidence: published reports on health system reforms by World Health Organization, World Bank, Organization for Economic Co-operation and Development, Canadian Institute for Health Information, Canadian Health Services Research Foundation, and Centre for Health Economics University of York. Diverse payment systems have different strengths and weaknesses in relation to the various objectives. The advantages of the DRG payment system are reflected in the increased efficiency and transparency and reduced average length of stay. The disadvantage of DRG is creating financial incentives toward earlier hospital discharges. Occasionally, such polices are not in full accordance with the clinical benefit priorities. PMID:28462278

[Offshore substation workers' exposure to harmful factors - Actions minimizing risk of hazards].

The current development of electric power industry in Poland, especially in the field of renewable energy sources, including wind power, brings about the need to introduce legislation on new work environment. The development of occupational safety and health (OSH) regulations that must be met by new workplaces, such as offshore substations becomes necessary in view of the construction of modern offshore wind power plants - offshore wind farms. Staying on offshore substation is associated with an increased exposure to harmful health factors: physical, chemical, biological and psychophysical. The main sources of health risks on offshore substations are: temperature, electromagnetic field, noise from operating wind turbines, direct and alternating current, chemicals, Legionella bacteria and social isolation of people. The aim of this article is to draw attention to the problem of offshore substation workers' exposure to harmful factors and to present methods of preventing and reducing the risk-related adverse health effects. In this paper, there are identified and described risks occurring on offshore substations (fire, explosion, lightning, accidents at work). Some examples of the means and the methods for reducing the negative impact of exposure on the human health are presented and discussed. The article also highlights the need to develop appropriate laws and health and safety regulations concerning the new working environment at the offshore substations. The review of researches and international standards shows that some of them can be introduced into the Polish labor market.

Thousands of Earth Observation satellite instrument products are generated daily, in a multitude of formats, using a variety of projection coordinate sytems. This diversity is a barrier to the development of EO multi-mission-based applications and prevents the merging of EO data with GIS data, which is requested by the user community (value-added companies, serivce providers, scientists, institutions, commercial users, and academic users). The web mapping technologies introduced in this article represent an elegant and low-technologies introduced in this article represent an elegant and low-cost solution. The extraordinary added value that is achieved may be considered a revolution in the use of EO data products.

Meditation research, past, present, and future: perspectives from the Nalanda contemplative science tradition

PubMed Central

Loizzo, Joseph

2014-01-01

This article offers an overview of meditation research: its history, recent developments, and future directions. As the number and scope of studies grow, the field has converged with cognitive and affective neuroscience, and spawned many clinical applications. Recent work has shed light on the mechanisms and effects of diverse practices, and is entering a new phase where consensus and coherent paradigms are within reach. This article suggests an unusual path for future advancement: complementing conventional research with rigorous dialogue with the contemplative traditions that train expert meditators and best know the techniques. It explores the Nalanda tradition developed in India and preserved in Tibet, because its cumulative approach to contemplative methods produced a comprehensive framework that may help interpret data and guide research, and because its naturalistic theories and empirical methods may help bridge the gulf between science and other contemplative traditions. Examining recent findings and models in light of this framework, the article introduces the Indic map of the central nervous system and presents three testable predictions based on it. Finally, it reviews two studies that suggest that the multimodal Nalanda approach to contemplative learning is as well received as more familiar approaches, while showing promise of being more effective.

The birth of plastic surgery: the story of nasal reconstruction from the Edwin Smith Papyrus to the twenty-first century.

The nose is the central and most prominent feature on the human face; and on its shape, size, and appearance depends the relative facial beauty of the person. The objective of this article was to give a succinct and interesting account of the development of nasal reconstruction from antiquity to the present day. The authors present the story of nasal reconstruction, including those contributions not often cited in the English literature using articles sourced from MEDLINE, ancient manuscripts, original quotes, techniques, and illustrations. The story of rhinoplasty is one of peaks of achievement by individuals such as Sushruta, Branca, Tagliocozzi, Roe, and Joseph. Since Roe introduced the concept of cosmetic rhinoplasty, the evolution of nasal reconstructive techniques has reached such a level that the expectation is not only to restore form and function, but also to achieve excellent cosmetic appearance. Although repair of nasal injuries is the oldest form of reconstructive surgery, being cited in Egyptian papyrus inscriptions such as the Edwin Smith Papyrus dating back to 2500 to 3000 BC, its complexity continues to challenge surgeons today. This article is dedicated to those individuals who have devoted their lives and work to the advancement of the field of plastic surgery for the benefit of mankind.

Using History to Teach Mathematics: The Case of Logarithms

NASA Astrophysics Data System (ADS)

Panagiotou, Evangelos N.

2011-01-01

Many authors have discussed the question why we should use the history of mathematics to mathematics education. For example, Fauvel (For Learn Math, 11(2): 3-6, 1991) mentions at least fifteen arguments for applying the history of mathematics in teaching and learning mathematics. Knowing how to introduce history into mathematics lessons is a more difficult step. We found, however, that only a limited number of articles contain instructions on how to use the material, as opposed to numerous general articles suggesting the use of the history of mathematics as a didactical tool. The present article focuses on converting the history of logarithms into material appropriate for teaching students of 11th grade, without any knowledge of calculus. History uncovers that logarithms were invented prior of the exponential function and shows that the logarithms are not an arbitrary product, as is the case when we leap straight in the definition given in all modern textbooks, but they are a response to a problem. We describe step by step the historical evolution of the concept, in a way appropriate for use in class, until the definition of the logarithm as area under the hyperbola. Next, we present the formal development of the theory and define the exponential function. The teaching sequence has been successfully undertaken in two high school classrooms.
