Moulding techniques in lipstick manufacture: a comparative evaluation.
Dweck, A C; Burnham, C A
1980-06-01
Synopsis This paper examines two methods of lipstick bulk manufacture: one via a direct method and the other via stock concentrates. The paper continues with a comparison of two manufactured bulks moulded in three different ways - first by split moulding, secondly by Rotamoulding, and finally by Ejectoret moulding. Full consideration is paid to time, labour and cost standards of each approach and the resultant moulding examined using some novel physical testing methods. The results of these tests are statistically analysed. Finally, on the basis of the gathered data and photomicrographical work a theoretical lipstick structure is proposed by which the results may be explained.

Examination of Frameworks for Safe Integration of Intelligent Small UAS into the NAS
NASA Technical Reports Server (NTRS)
Logan, Michael J.
2012-01-01
This paper discusses a proposed framework for the safe integration of small unmanned aerial systems (sUAS) into the National Airspace System (NAS). The paper briefly examines the potential uses of sUAS to build an understanding of the location and frequency of potential future flight operations based on the future applications of the sUAS systems. The paper then examines the types of systems that would be required to meet the application-level demand to determine "classes" of platforms and operations. A framework for categorization of the "intelligence" level of the UAS is postulated for purposes of NAS integration. Finally, constraints on the intelligent systems are postulated to ensure their ease of integration into the NAS.

The demanding and intense environment of medical training can create excessive pressures on medical students that eventually lead to unfavorable consequences, either at a personal or professional level. These consequences can include poor academic performance and impaired cognitive ability. This study was designed to explore associations between pass-fail outcome and psychological health parameters (i.e. stress, anxiety, and depression symptoms). A cross-sectional study was conducted on a cohort of first-year medical students in a Malaysian medical school. The depression anxiety stress scale 21-item assessment (DASS-21) was administered to them right after the final paper of the first-year final examination. Their final examination outcomes (i.e. pass or fail) were traced by using their student identity code (ID) through the Universiti Sains Malaysia academic office. A total of 194 (98.0%) of medical students responded to the DASS-21. An independent t-test showed that students who passed had significantly lower stress, anxiety, and depression symptoms than those who failed the first-year final examination (P <0.05). Those who experienced moderate to high stress were at 2.43 times higher risk for failing the examination than those who experienced normal to mild stress. Medical students who failed in the final examination had higher psychological distress than those who passed the examination. Those who experienced high stress levels were more likely to fail than those who did not. Reducing the psychological distress of medical students prior to examination may help them to perform better in the examination.

This paper examines the role of land-based air power within a national maritime strategy. Corbett taught that naval strategy is a subsidiary aspect of a national maritime strategy; and the increasing speed, range, and accuracy of aircraft, weapons, detection, and communications ensure that an important part of maritime air control will be land-based. To evaluate that claim, this paper examines the unity of sea control and air control; examines the Air Force missions that affect sea control; discusses the strategic concerns directing land-based air in maritime strategy; and explains why joint strategic doctrine will better integrate our military forces.

Midwifery: "at the edge of history".
Dahlen, H
2006-03-01
The paper focuses on possible future pathways in maternity care for midwives and nations to consider. The paper blends personal and professional experiences to outline priority areas facing midwives in the future. It begins by examining maternal mortality and morbidity in the developing world and considering the potential of the ten high priority action messages (1997) in helping to improve the plight of women and children in the future. The paper then examines major issues facing midwives in the developed world including: the way birth is viewed; the medical-midwifery divide; marketing midwifery; and finally the challenge of dealing with fear around birth. The third part of the paper examines a part of society where the two worlds meet and there are issues from both the developed and developing world to consider. The paper focuses on women from culturally and linguistically diverse communities, Aboriginal and Torres Strait Islander women and women birthing in remote and rural areas. By looking at these three worlds separately the paper examines different concerns facing midwives in the future but also draws on common issues that face us all as citizens of this planet and particularly as predominantly women. The paper challenges midwives to be politically active and dare to change the world.

Science and worldviews in the marxist tradition
NASA Astrophysics Data System (ADS)
Skordoulis, C. D.
2008-06-01
This paper is about the relationship between Marxism, Science and Worldviews. In Section I, the paper gives a descriptive definition of the scientific viewpoint based on a materialist ontology, a realist epistemology, and the recognition that science is a social activity. The paper shows in Section II that there are currents in contemporary Marxism which relate favourably to science. In Section III, the paper examines Marx's encounter with Natural Philosophy and Materialism by analysing the influence of Epicurus on Marx. Section IV examines Marx's positive attitude towards natural science. Section V discusses the relation between science and ideology and proposes a scheme to defend the thesis that science establishes a conceptual autonomy from the forms of social consciousness existing in the social formation. Finally Section VI examines the historical infusion of Marxism into the Western scientific community in the 1930s, and the positions adopted by Marxists when they have considered science education.

Clinician Responses to Client Traumas: A Chronological Review of Constructs and Terminology.
Newell, Jason M; Nelson-Gardell, Debra; MacNeil, Gordon
2016-07-01
This paper presents a chronologically-organized review of various concepts and constructs in the literature describing professional burnout, compassion fatigue, secondary traumatic stress reactions, as well as other related terms and constructs that have been used to describe these experiences among clinical practitioners and other social service professionals. A timeline will provide a graphic illustration of the historical relationships between the concepts under examination. This paper begins with a review of practitioner-related stress that primarily results from interaction with clients, followed by an examination of professional burnout, which is thought to result largely from environmentally-related issues. Finally, the paper concludes with a discussion of posttraumatic growth and compassion satisfaction. © The Author(s) 2015.
Optimisation in radiotherapy. III: Stochastic optimisation algorithms and conclusions.
Ebert, M
1997-12-01
This is the final article in a three part examination of optimisation in radiotherapy. Previous articles have established the bases and form of the radiotherapy optimisation problem, and examined certain types of optimisation algorithm, namely, those which perform some form of ordered search of the solution space (mathematical programming), and those which attempt to find the closest feasible solution to the inverse planning problem (deterministic inversion). The current paper examines algorithms which search the space of possible irradiation strategies by stochastic methods. The resulting iterative search methods move about the solution space by sampling random variates, which gradually become more constricted as the algorithm converges upon the optimal solution. This paper also discusses the implementation of optimisation in radiotherapy practice.

Research on emotional intelligence (EI) suggests that it is associated with more pro-social behavior, better academic performance and improved empathy towards patients. In medical education and clinical practice, EI has been related to higher academic achievement and improved doctor-patient relationships. This study examined the effect of EI on academic performance in first- and final-year medical students in Malaysia. This was a cross-sectional study using an objectively-scored measure of EI, the Mayer-Salovey-Caruso Emotional Intelligence Test (MSCEIT). Academic performance of medical school students was measured using continuous assessment (CA) and final examination (FE) results. The first- and final-year students were invited to participate during their second semester. Students answered a paper-based demographic questionnaire and completed the online MSCEIT on their own. Relationships between the total MSCEIT score to academic performance were examined using multivariate analyses. A total of 163 (84 year one and 79 year five) medical students participated (response rate of 66.0%). The gender and ethnic distribution were representative of the student population. The total EI score was a predictor of good overall CA (OR 1.01), a negative predictor of poor result in overall CA (OR 0.97), a predictor of the good overall FE result (OR 1.07) and was significantly related to the final-year FE marks (adjusted R(2) = 0.43). Medical students who were more emotionally intelligent performed better in both the continuous assessments and the final professional examination. Therefore, it is possible that emotional skill development may enhance medical students' academic performance.

In this, the first of two papers concerned with the use of numerical simulation to examine flow and transport parameters in heterogeneous porous media via Monte Carlo methods, various aspects of the modelling effort are examined. In particular, the need to save on core memory causes one to use only specific realizations that have certain initial characteristics; in effect, these transport simulations are conditioned by these characteristics. Also, the need to independently estimate length scales for the generated fields is discussed. The statistical uniformity of the flow field is investigated by plotting the variance of the seepage velocity for vector components in the x, y, and z directions. Finally, specific features of the velocity field itself are illuminated in this first paper. In particular, these data give one the opportunity to investigate the effective hydraulic conductivity in a flow field which is approximately statistically uniform; comparisons are made with first- and second-order perturbation analyses. The mean cloud velocity is examined to ascertain whether it is identical to the mean seepage velocity of the model. Finally, the variance in the cloud centroid velocity is examined for the effect of source size and differing strengths of local transverse dispersion.

There is an art to writing a scientific paper so that it communicates accurately, succinctly, and comprehensively. Developing this art comes with experience, and sharing that experience with younger physicists is an obligation of senior scientists, especially those with editorial responsibilities for the journal. In this workshop, the preparation of a scientific manuscript will be dissected so participants can appreciate how each part is developed and then assembled into a complete paper. Then the review process for the paper will be discussed, including how to examine a paper and write an insightful and constructive review. Finally, we will consider the challenge of accommodating the concerns and recommendations of a reviewer in preparing a revision of the paper. A second feature of the workshop will be a discussion of the process of electronic submission of a paper for consideration by Medical Physics. The web-based PeerX-Press engine for manuscript submission and management will be examined, with attention to special features such as epaps and line-referencing. Finally, new features of Medical Physics will be explained, such as Vision 20/20 manuscripts, Physics Letters and the standardized formatting of book reviews. 1. Improve the participants' abilities to write a scientific manuscript. 2. Understand the review process for Medical Physics manuscripts and how to participate in and benefit from it. 3. Appreciate the many features of the PeerX-Press electronic management process for Medical Physics manuscripts. 4.

Twenty-two papers on the study of tsunamis are included in Volume I of the PAGEOPH topical issue "Tsunami Science: Ten Years after the 2004 Indian Ocean Tsunami." Eight papers examine various aspects of past events with an emphasis on case and regional studies. Five papers are on tsunami warning and forecast, including the improvement of existing tsunami warning systems and the development of new warning systems in the northeast Atlantic and Mediterranean region. Three more papers present the results of analytical studies and discuss benchmark problems. Four papers report the impacts of tsunamis, including the detailed calculation of inundation onshore and into rivers and probabilistic analysis for engineering purposes. The final two papers relate to important investigations of the source and tsunami generation. Overall, the volume not only addresses the pivotal 2004 Indian Ocean (Sumatra) and 2011 Japan (Tohoku) tsunamis, but also examines the tsunami hazard posed to other critical coasts in the world.
Investigation into Cause of High Temperature Failure of Boiler Superheater Tube
NASA Astrophysics Data System (ADS)
Ghosh, D.; Ray, S.; Roy, H.; Shukla, A. K.
2015-04-01
The failure of the boiler tubes occur due to various reasons like creep, fatigue, corrosion and erosion. This paper highlights a case study of typical premature failure of a final superheater tube of 210 MW thermal power plant boiler. Visual examination, dimensional measurement, chemical analysis, oxide scale thickness measurement, microstructural examination are conducted as part of the investigations. Apart from these investigations, sulfur print, Energy Dispersive spectroscopy (EDS) and X ray diffraction analysis (XRD) are also conducted to ascertain the probable cause of failure of final super heater tube. Finally it has been concluded that the premature failure of the super heater tube can be attributed to the combination of localized high tube metal temperature and loss of metal from the outer surface due to high temperature corrosion. The corrective actions have also been suggested to avoid this type of failure in near future.

Multiple-choice examinations: adopting an evidence-based approach to exam technique.
Hammond, E J; McIndoe, A K; Sansome, A J; Spargo, P M
1998-11-01
Negatively marked multiple-choice questions (MCQs) are part of the assessment process in both the Primary and Final examinations for the fellowship of the Royal College of Anaesthetists. It is said that candidates who guess will lose marks in the MCQ paper. We studied candidates attending a pre-examination revision course and have shown that an evaluation of examination technique is an important part of an individual's preparation. All candidates benefited substantially from backing their educated guesses while only 3 out of 27 lost marks from backing their wild guesses. Failure to appreciate the relationship between knowledge and technique may significantly affect a candidate's performance in the examination.

Background Research on emotional intelligence (EI) suggests that it is associated with more pro-social behavior, better academic performance and improved empathy towards patients. In medical education and clinical practice, EI has been related to higher academic achievement and improved doctor-patient relationships. This study examined the effect of EI on academic performance in first- and final-year medical students in Malaysia. Methods This was a cross-sectional study using an objectively-scored measure of EI, the Mayer-Salovey-Caruso Emotional Intelligence Test (MSCEIT). Academic performance of medical school students was measured using continuous assessment (CA) and final examination (FE) results. The first- and final-year students were invited to participate during their second semester. Students answered a paper-based demographic questionnaire and completed the online MSCEIT on their own. Relationships between the total MSCEIT score to academic performance were examined using multivariate analyses. Results A total of 163 (84 year one and 79 year five) medical students participated (response rate of 66.0%). The gender and ethnic distribution were representative of the student population. The total EI score was a predictor of good overall CA (OR 1.01), a negative predictor of poor result in overall CA (OR 0.97), a predictor of the good overall FE result (OR 1.07) and was significantly related to the final-year FE marks (adjusted R2 = 0.43). Conclusions Medical students who were more emotionally intelligent performed better in both the continuous assessments and the final professional examination. Therefore, it is possible that emotional skill development may enhance medical students’ academic performance. PMID:23537129

This paper examines narrative methodologies as one approach to exploring issues of gender, education and social justice and, particularly, insights into "undoing gender". It furthermore examines the possibilities of exploring gender and its multiple intersections in a range of global and policy contexts through the use of personal experience approaches. The "storying" of lived experience is examined as a means of challenging dominant discourses which can construct and other individuals and groups in relation to many aspects of gender and education. Drawing on intersectionality, as a complex and developing feminist theory, the paper considers ways in which narrative can illuminate often hidden complexities while seeking to avoid generalisations and essentialisms. The difficulties of using narrative in relation to these aims are explored in the light of the warnings of feminist writers such as Michele Fine and bell hooks. The paper briefly considers narrative as both methodology and phenomenon, and finally, drawing on critical discourse analysis, discusses the potential of intersectionality and narrative in relation to undoing gender.

In this paper, we examine common methods for using individual-level data to represent classroom composition by examining exemplary studies that thoughtfully incorporate such measures. Building on these studies, and using data from the Chicago School Readiness Project (CSRP), this paper examines theoretical and analytical implications of a set of different transformations of individual ratings of child externalizing behaviors in order to examine and compare the influence of these representations of classroom composition on Kindergarten internalizing behaviors, social competence, and attention/impulsivity problems. Results indicate that each Kindergarten outcome is influenced by distinct aspects of classroom composition of externalizing behaviors. Kindergarten internalizing behaviors are positively associated with the proportion of children in the Head Start classroom who started with externalizing scores above the 75th percentile regardless of the average value of externalizing behaviors in the classroom. In contrast, Kindergarten social competence is predicted by three aspects of the classroom distribution of externalizing behaviors in the fall of Head Start—the classroom mean, standard deviation, and skew. Finally, Kindergarten attention/impulsivity problems were not associated with any aspect of classroom composition of externalizing behavior examined in this paper. PMID:28275289

Finally, the basic rationale of industrial monitoring programs is discussed within the context of the emerging legal issues.
The concept of hierarchy in general systems theory.
Gasparski, W
1994-01-01
The paper reviews main ideas related to the concept of hierarchy as they are discussed in contemporary general systems theory. After presenting a dictionary definition of the concept, the author examines the intuitive idea of hierarchy quoting Mario Bunge's notion of level structure. Then relationship between two other concepts: a system and a hierarchy is characterised on the bases of Bowler's, Bunge's again, Klir's, and the author's studies. Finally, the paper is concluded that hierarchy is not an otological concept but epistemological one.
Can We Falsify the Consciousness-Causes-Collapse Hypothesis in Quantum Mechanics?

de Barros, J. Acacio; Oas, Gary
2017-10-01
In this paper we examine some proposals to disprove the hypothesis that the interaction between mind and matter causes the collapse of the wave function, showing that such proposals are fundamentally flawed. We then describe a general experimental setup retaining the key features of the ones examined, and show that even a more general case is inadequate to disprove the mind-matter collapse hypothesis. Finally, we use our setup provided to argue that, under some reasonable assumptions about consciousness, such hypothesis is unfalsifiable.
Mitochondrial replacement techniques: egg donation, genealogy and eugenics.
Palacios-González, César
2016-03-01
Several objections against the morality of researching or employing mitochondrial replacement techniques have been advanced recently. In this paper, I examine three of these objections and show that they are found wanting. First I examine whether mitochondrial replacement techniques, research and clinical practice, should not be carried out because of possible harms to egg donors. Next I assess whether mitochondrial replacement techniques should be banned because they could affect the study of genealogical ancestry. Finally, I examine the claim that mitochondrial replacement techniques are not transferring mitochondrial DNA but nuclear DNA, and that this should be prohibited on ethical grounds.

The ethics and economics of consuming Canadian drugs.
Seaman, Rachel M H
2005-01-01
Many U.S. citizens are unable to afford prescription medication in their own country, so they purchase them from Canadian pharmacies. This paper examines the ethics of importing drugs from Canada, including economic implications and how physicians should respond to this dilemma. The four basic principles of ethics are balanced by examining financial incentives, current Canadian and U.S. law, safety issues, the burden of research and development, the impact on Canadian physicians, and issues of liability. The paper concludes that the principle of autonomy permits individuals to cross the border and purchase drugs for personal use; however, nonmaleficence prohibits the purchase of these drugs through third parties. In addition, the U.S. government has special obligations to justice and beneficence and may not ethically sponsor the importation of Canadian drugs. Finally, the paper shows that U.S. doctors must not recommend importation on the basis of beneficence and autonomy.

Morris, Paul
1990-03-01
This paper examines an attempt to promote a school centred innovation strategy within a highly centralized educational system. The School Based Curriculum Project Scheme, which was introduced into Hong Kong in 1988, is analysed in terms of a professional-bureaucratic dichotomy. It is argued that the operational details of the scheme are designed to satisfy a range of bureaucratic concerns and these are not conducive to promoting the professional work ethic which is required for school centred innovation. Finally the paper identifies the implications which arise for policies designed to promote curriculum innovation.

Student-written single-best answer questions predict performance in finals.
Walsh, Jason; Harris, Benjamin; Tayyaba, Saadia; Harris, David; Smith, Phil
2016-10-01
Single-best answer (SBA) questions are widely used for assessment in medical schools; however, often clinical staff have neither the time nor the incentive to develop high-quality material for revision purposes. A student-led approach to producing formative SBA questions offers a potential solution. Cardiff University School of Medicine students created a bank of SBA questions through a previously described staged approach, involving student question-writing, peer-review and targeted senior clinician input. We arranged questions into discrete tests and posted these online. Student volunteer performance on these tests from the 2012/13 cohort of final-year medical students was recorded and compared with the performance of these students in medical school finals (knowledge and objective structured clinical examinations, OSCEs). In addition, we compared the performance of students that participated in question-writing groups with the performance of the rest of the cohort on the summative SBA assessment. Often clinical staff have neither the time nor the incentive to develop high-quality material for revision purposes Performance in the end-of-year summative clinical knowledge SBA paper correlated strongly with performance in the formative student-written SBA test (r = ~0.60, p <0.01). There was no significant correlation between summative OSCE scores and formative student-written SBA test scores. Students who wrote and reviewed questions scored higher than average in the end-of-year summative clinical knowledge SBA paper. Student-written SBAs predict performance in end-of-year SBA examinations, and therefore can provide a potentially valuable revision resource. There is potential for student-written questions to be incorporated into summative examinations. © 2015 John Wiley & Sons Ltd.

Almost from its birth, the computer and video gaming industry has done an admirable job of communicating the vision and attempting to convey the experience of traveling through space to millions of gamers from all cultures and demographics. This paper will propose several approaches the 100 Year Starship Study can take to use the power of interactive media to stir interest in the Starship and related projects among a global population. It will examine successful gaming franchises from the past that are relevant to the mission and consider ways in which the Starship Study could cooperate with game development studios to bring the Starship vision to those franchises and thereby to the public. The paper will examine ways in which video games can be used to crowd-source research aspects for the Study, and how video games are already considering many of the same topics that will be examined by this Study. Finally, the paper will propose some mechanisms by which the 100 Year Starship Study can establish very close ties with the gaming industry and foster cooperation in pursuit of the Study's goals.

Spirituality as a Positive Youth Development Construct: A Conceptual Review
Shek, Daniel T. L.
2012-01-01
The concept of spirituality as a positive youth development construct is reviewed in this paper. Both broad and narrow definitions of spirituality are examined and a working definition of spirituality is proposed. Regarding theories of spirituality, different models pertinent to spiritual development and the relationship between spirituality and positive youth development are highlighted. Different ecological factors, particularly family and peer influences, were found to influence spirituality. Research on the influence of spirituality on adolescent developmental outcomes is examined. Finally, ways to promote adolescent spirituality are discussed. PMID:22654611
A Computerized Hospital Patient Information Management System
Wig, Eldon D.
1982-01-01
The information processing needs of a hospital are many, with varying degrees of complexity. The prime concern in providing an integrated hospital information management system lies in the ability to process the data relating to the single entity for which every hospital functions - the patient. This paper examines the PRIMIS computer system developed to accommodate hospital needs with respect to a central patient registry, inpatients (i.e., Admission/Transfer/Discharge), and out-patients. Finally, the potential for expansion to permit the incorporation of more hospital functions within PRIMIS is examined.
Satellite diversity and its implications on the RAKE receiver architecture for CDMA-based S-PCN's

In this paper we examine the applicability of RAKE receivers in a mobile LEO satellite channel and identify the potential problem areas. We then proceed to investigate the possibility of a coherent combining architecture (downlink) in the presence of satellite diversity. We closely examine the path delay difference statistics of a diversity channel and propose a delay compensation scheme for the downlink in order to reduce the complexity of the user terminal. Finally, the required modifications to the conventional RAKE receiver are proposed and discussed.
Alternative sample sizes for verification dose experiments and dose audits

Taylor, W. A.; Hansen, J. M.
1999-01-01
ISO 11137 (1995), "Sterilization of Health Care Products—Requirements for Validation and Routine Control—Radiation Sterilization", provides sampling plans for performing initial verification dose experiments and quarterly dose audits. Alternative sampling plans are presented which provide equivalent protection. These sampling plans can significantly reduce the cost of testing. These alternative sampling plans have been included in a draft ISO Technical Report (type 2). This paper examines the rational behind the proposed alternative sampling plans. The protection provided by the current verification and audit sampling plans is first examined. Then methods for identifying equivalent plans are highlighted. Finally, methods for comparing the cost associated with the different plans are provided. This paper includes additional guidance for selecting between the original and alternative sampling plans not included in the technical report.
A new approach on seismic mortality estimations based on average population density
NASA Astrophysics Data System (ADS)
Zhu, Xiaoxin; Sun, Baiqing; Jin, Zhanyong
2016-12-01
This study examines a new methodology to predict the final seismic mortality from earthquakes in China. Most studies established the association between mortality estimation and seismic intensity without considering the population density. In China, however, the data are not always available, especially when it comes to the very urgent relief situation in the disaster. And the population density varies greatly from region to region. This motivates the development of empirical models that use historical death data to provide the path to analyze the death tolls for earthquakes. The present paper employs the average population density to predict the final death tolls in earthquakes using a case-based reasoning model from realistic perspective. To validate the forecasting results, historical data from 18 large-scale earthquakes occurred in China are used to estimate the seismic morality of each case. And a typical earthquake case occurred in the northwest of Sichuan Province is employed to demonstrate the estimation of final death toll. The strength of this paper is that it provides scientific methods with overall forecast errors lower than 20 %, and opens the door for conducting final death forecasts with a qualitative and quantitative approach. Limitations and future research are also analyzed and discussed in the conclusion.

Any leak in one of the ITER actively cooled components would cause significant consequences for machine operations; therefore, the risk of leak must be minimized as much as possible. In this paper, the strategy of examination to ensure leak tightness of the ITER internal components (i.e. examination of base materials, vacuum boundary joints and final components) and the hydraulic parameters for ITER internal components are summarized. The experiences of component tests, especially hot helium leak tests in recent fusion devices, were reviewed and the parameters were discussed. Through these experiences, it was confirmed that the hot He leak test was effective to detect small leak paths which were not always possible to detect by volumetric examination due to limited spatial resolution.
The Moral Insignificance of Self‐consciousness
2017-01-01
Abstract In this paper, I examine the claim that self‐consciousness is highly morally significant, such that the fact that an entity is self‐conscious generates strong moral reasons against harming or killing that entity. This claim is apparently very intuitive, but I argue it is false. I consider two ways to defend this claim: one indirect, the other direct. The best‐known arguments relevant to self‐consciousness's significance take the indirect route. I examine them and argue that (a) in various ways they depend on unwarranted assumptions about self‐consciousness's functional significance, and (b) once these assumptions are undermined, motivation for these arguments dissipates. I then consider the direct route to self‐consciousness's significance, which depends on claims that self‐consciousness has intrinsic value or final value. I argue what intrinsic or final value self‐consciousness possesses is not enough to generate strong moral reasons against harming or killing. PMID:28919670

An orthopedist's guide to shoulder ultrasound: a systematic review of examination protocols.
Amoo-Achampong, Kelms; Nwachukwu, Benedict U; McCormick, Frank
2016-11-01
The utilization of musculoskeletal ultrasound has expanded within the setting of the orthopedic clinic as a cost-effective, point-of-care diagnostic tool for shoulder pathology. In experienced hands, ultrasound exhibits capabilities equivalent to that of magnetic resonance imaging in the diagnosis of many shoulder diseases including full-thickness and partial-thickness rotator cuff tears. Although similarly effective in identifying additional shoulder disease processes, major obstacles to its widespread use include user dependence and intrinsic limitation to extra-articular diagnosis. The purpose of this review is to present a step-by-step guide of how to perform a comprehensive shoulder examination and to discuss the appropriate use, economic benefit and implementation of ultrasound within the clinic. A systematic search (June 2016) of PubMed, Scopus, and EMBASE databases was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines for literature presenting shoulder ultrasound examination protocols. Included studies were peer-reviewed articles or academic society endorsed protocols presenting comprehensive sonographic examinations of the adult shoulder. Papers with limited or single structure examination descriptions, non-English language, and publication dates before 1980 were excluded. Final papers meeting criteria were secondarily screened for publication after 2005 to reflect the current state of ultrasound imaging. The search yielded 1,725 unique articles with 17 studies meeting final selection criteria. Information from identified studies was summarized to formulate a 4-part shoulder examination protocol, including steps most pertinent to orthopedic in-office diagnoses. In agreement with previous studies, the inexperienced orthopedic surgeon can be quickly trained to expert level proficiency in shoulder ultrasound diagnosis. Using an established protocol, a comprehensive, yet effective shoulder ultrasound examination can be performed within ten minutes. Further, ultrasound provides opportunity to off-set costs through the engagement of revenue generating activity for the orthopedic practice.

This paper explores current conceptual understanding of urban social, environmental, and health inequality and inequity, and looks at the impact of these processes on urban children and young people in the 21st century. This conceptual analysis was commissioned for a discussion paper for UNICEF's flagship publication: State of the World's Children 2012: Children in an Urban World. The aim of the paper is to examine evidence on the meaning of urban inequality and inequity for urban children and young people. It further looks at the controversial policies of targeting "vulnerable" young people, and policies to achieve the urban MDGs. Finally, the paper looks briefly at the potential of concepts such as environment justice and rights to change our understanding of urban inequality and inequity.

This paper examines the traditional engineering-based provision delivered to Product Design and Technology (B.Sc.) undergraduates at the Loughborough Design School and questions its relevancy against the increasing expectations of industry. The paper reviews final-year design projects to understand the level of transference of engineering-based knowledge into design practice and highlights areas of opportunity for improved teaching and learning. The paper discusses the development and implementation of an integrated approach to the teaching of Mechanics and Electronics to formalise and reinforce the key learning process of transference within the design context. The paper concludes with observations from the delivery of this integrated teaching and offers insights from student and academic perspectives for the further improvement of engineering-based teaching and learning.
Evidence of virtual patients as a facilitative learning tool on an anesthesia course.
Leung, Joseph Y C; Critchley, Lester A H; Yung, Alex L K; Kumta, Shekhar M
2015-10-01
Virtual patients are computerised representations of realistic clinical cases. They were developed to teach clinical reasoning skills through delivery of multiple standardized patient cases. The anesthesia course at The Chinese University of Hong Kong developed two novel types of virtual patients, formative assessment cases studies and storyline, to teach its final year medical students on a 2 week rotational course. Acute pain management cases were used to test if these two types of virtual patient could enhance student learning. A 2 × 2 cross over study was performed in academic year 2010-2011 on 130 students divided into four groups of 32-34. Performance was evaluated by acute pain management items set within three examinations; an end of module 60-item multiple choice paper, a short answer modified essay paper and the end of year final surgery modified essay paper. The pain management case studies were found to enhanced student performance in all three examinations, whilst the storyline virtual patient had no demonstrable effect. Student-teaching evaluation questionnaires showed that the case studies were favored more than the storyline virtual patient. Login times showed that students on average logged onto the case studies for 6 h, whereas only half the students logged on and used the storyline virtual patient. Formative assessment case studies were well liked by the students and reinforced learning of clinical algorithms through repetition and feedback, whereas the educational role of the more narrative and less interactive storyline virtual patient was less clear .

In this forum, I extend Tao, Oliver, and Venville's paper Chinese and Australian children's understanding of the earth: a cross cultural study of conceptual development to discuss the different views on culture and cultural mediation. I tease out nuances in the viewpoints to suggest three ways to theoretically frame studies examining cultural mediation of students' cognition. Specifically, cultural mediation may be attributed to innate psychological attributes, an accretion of cultural elements, or the social interaction process. Each of these ideas represents a theoretical lens and has implications for the research design of studies relating cultural mediation to cognition. In the final section of this forum paper, I show how a study conducted from the symbolic interactionist viewpoint underscoring cultural mediation as a social interaction process might unfold.
Salient features of dependence in daily US stock market indices

This paper deals with the analysis of long range dependence in the US stock market. We focus first on the log-values of the Dow Jones Industrial Average, Standard and Poors 500 and Nasdaq indices, daily from February, 1971 to February, 2007. The volatility processes are examined based on the squared and the absolute values of the returns series, and the stability of the parameters across time is also investigated in both the level and the volatility processes. A method that permits us to estimate fractional differencing parameters in the context of structural breaks is conducted in this paper. Finally, the “day of the week” effect is examined by looking at the order of integration for each day of the week, providing also a new modeling approach to describe the dependence in this context.
Exploring empowerment in settings: mapping distributions of network power.
Neal, Jennifer Watling
2014-06-01
This paper brings together two trends in the empowerment literature-understanding empowerment in settings and understanding empowerment as relational-by examining what makes settings empowering from a social network perspective. Specifically, extending Neal and Neal's (Am J Community Psychol 48(3/4):157-167, 2011) conception of network power, an empowering setting is defined as one in which (1) actors have existing relationships that allow for the exchange of resources and (2) the distribution of network power among actors in the setting is roughly equal. The paper includes a description of how researchers can examine distributions of network power in settings. Next, this process is illustrated in both an abstract example and using empirical data on early adolescents' peer relationships in urban classrooms. Finally, implications for theory, methods, and intervention related to understanding empowering settings are explored.

Floor space allowance for pigs has substantial effects on pig growth and welfare. Data from 30 papers examining the influence of floor space allowance on the growth of finishing pigs was used in a meta-analysis to develop alternative prediction equations for average daily gain (ADG), average daily feed intake (ADFI) and gain : feed ratio (G : F). Treatment means were compiled in a database that contained 30 papers for ADG and 28 papers for ADFI and G : F. The predictor variables evaluated were floor space (m2/pig), k (floor space/final BW0.67), Initial BW, Final BW, feed space (pigs per feeder hole), water space (pigs per waterer), group size (pigs per pen), gender, floor type and study length (d). Multivariable general linear mixed model regression equations were used. Floor space treatments within each experiment were the observational and experimental unit. The optimum equations to predict ADG, ADFI and G : F were: ADG, g=337.57+(16 468×k)-(237 350×k 2)-(3.1209×initial BW (kg))+(2.569×final BW (kg))+(71.6918×k×initial BW (kg)); ADFI, g=833.41+(24 785×k)-(388 998×k 2)-(3.0027×initial BW (kg))+(11.246×final BW (kg))+(187.61×k×initial BW (kg)); G : F=predicted ADG/predicted ADFI. Overall, the meta-analysis indicates that BW is an important predictor of ADG and ADFI even after computing the constant coefficient k, which utilizes final BW in its calculation. This suggests including initial and final BW improves the prediction over using k as a predictor alone. In addition, the analysis also indicated that G : F of finishing pigs is influenced by floor space allowance, whereas individual studies have concluded variable results.

Although the recommendation to avoid animal flesh for environmental reasons has been increasingly advanced, especially in the highly industrialized countries, the ecological implications of such avoidance are seldom carefully examined. If sustainable food systems are to be modeled after natural systems that maintain fertility, both plants and animals would be involved. This paper examines the history of the idea that environmental responsibility is linked to vegetarianism and the destructive effects of present methods of animal raising on farmers, animal welfare, and the environment. Finally, it explores the question of whether vegetarianism is the appropriate response to these problems.

The quiet revolution: reporting of health outcomes in general medical journals.
Seymour, J; Newell, D; Shiell, A
1997-01-01
This study reviews the extent of evaluation of health outcomes in three general medical journals over the past decade by examining papers published in the original research section of the New England Journal of Medicine (NEJM), The Lancet, and the Medical Journal of Australia (MJA) in 1982 and 1992. Evaluations were identified and classified according to the type of comparison group and the type of outcome measures employed. They were divided into three categories: those employing a comparison group; those employing a before-and-after study design (or own comparison group); and those with no comparison group. The categories of outcome measures were mortality, clinical or intermediate measures of health state, and final outcome measures (quality of life). Results show that the proportion of papers evaluating a health services intervention remained stable over the period. However, the MJA published considerably fewer evaluations than the other journals. In the NEJM and The Lancet, 75 per cent of evaluations incorporated comparison groups, in the MJA, less than 40 per cent. Overall, the proportion of papers reporting final outcome measures increased significantly between 1982 and 1992 (p = 0.04) but the change in each journal individually did not reach statistical significance. This study indicates that the reporting of health outcomes evaluations has remained constant but there has been some change in the use of comparison groups and final outcome measures over time.
Exploring the relationship between client perspectives, clinical expertise and research evidence.
Roulstone, Sue
2015-06-01
This paper examines the relationship between components of evidence-based practice (clinical expertise, patient perspective and research evidence). Findings are examined from two research programs: the Better Communication Research Program and Child Talk, including exploratory studies of the views of parents and children regarding speech-language pathology and studies of current practice by SLPs in England. Systematic reviews of the research literature were also undertaken. The paper analyses relationships between outcomes valued by children and parents and those reported in the literature and in practice, parents' perspectives regarding intervention in comparison with clinicians' reports of practice and the extent to which research evidence underpins current practice is examined. Parents and children value functional outcomes and positive experiences; these are not routinely measured in research or practice. Therapy is perceived positively by most parents; however, some are ambivalent and less clear about the rationale. Commonly used interventions are supported by evidence, but there are gaps regarding some critical therapy components. The paper discusses four challenges to evidence-based practice: the consistency and clarity of descriptions of interventions; consensus based models of practice; understanding of the mechanisms of change; and, finally, the operationalization of client preferences within an evidence-based practice framework.

Hypnosis and belief: A review of hypnotic delusions.
Connors, Michael H
2015-11-01
Hypnosis can create temporary, but highly compelling alterations in belief. As such, it can be used to model many aspects of clinical delusions in the laboratory. This approach allows researchers to recreate features of delusions on demand and examine underlying processes with a high level of experimental control. This paper reviews studies that have used hypnosis to model delusions in this way. First, the paper reviews studies that have focused on reproducing the surface features of delusions, such as their high levels of subjective conviction and strong resistance to counter-evidence. Second, the paper reviews studies that have focused on modelling underlying processes of delusions, including anomalous experiences or cognitive deficits that underpin specific delusional beliefs. Finally, the paper evaluates this body of research as a whole. The paper discusses advantages and limitations of using hypnotic models to study delusions and suggests some directions for future research. Copyright © 2015 Elsevier Inc. All rights reserved.
Roles for international military medical services in stability operations (security sector reform).
Bricknell, M C M; Thompson, D
2007-06-01
This is the second in a series of three papers that examine the role of international military medical services in stability operations in unstable countries. The paper discusses security sector reform in general terms and highlights the interdependency of the armed forces, police, judiciary and penal systems in creating a 'secure environment'. The paper then looks at components of a local military medical system for a counter-insurgency campaign operating on interior lines and the contribution and challenges faced by the international military medical community in supporting the development of this system. Finally the paper highlights the importance of planning the medical support of the international military personnel who will be supporting wider aspects of security sector reform. The paper is based on background research and my personal experience as Medical Director in the Headquarters of the NATO International Stability Assistance Force in Afghanistan in 2006.
Utilization and value of personal digital assistants on an epidemiology final examination.
Lawler, Frank H; Cacy, Jim
2005-01-01
The utility of personal digital assistants (PDAs) in basic science medical education is uncertain. Student outcomes on an epidemiology course final examination for academic years 2003 and 2004 were examined. Students were given permission to use PDAs on the final examination, and self-selected whether these instruments were used. Performance on the examination based on use of a PDA and whether students thought it was useful for the examination was compared. A total of 389 students took the final examination, with an 88% response rate to the survey questions. No statistically significant differences were found on final examination scores. No trends toward significance were found on analyses of the total examination, specific topical domains, or on specific questions where a PDA might be expected to be especially useful. From this study, it can be concluded that use of PDAs and whether students thought they might be helpful had no measurable effect on performance on an epidemiology final examination. Further delineation of the possible use of PDAs in a basic science course and on the final examination is indicated.
Ionization Suppression and Recovery in Direct Biofluid Analysis Using Paper Spray Mass Spectrometry
NASA Astrophysics Data System (ADS)
Vega, Carolina; Spence, Corina; Zhang, Chengsen; Bills, Brandon J.; Manicke, Nicholas E.
2016-04-01
Paper spray mass spectrometry is a method for the direct analysis of biofluid samples in which extraction of analytes from dried biofluid spots and electrospray ionization occur from the paper on which the dried sample is stored. We examined matrix effects in the analysis of small molecule drugs from urine, plasma, and whole blood. The general method was to spike stable isotope labeled analogs of each analyte into the spray solvent, while the analyte itself was in the dried biofluid. Intensity of the labeled analog is proportional to ionization efficiency, whereas the ratio of the analyte intensity to the labeled analog in the spray solvent is proportional to recovery. Ion suppression and recovery were found to be compound- and matrix-dependent. Highest levels of ion suppression were obtained for poor ionizers (e.g., analytes lacking basic aliphatic amine groups) in urine and approached -90%. Ion suppression was much lower or even absent for good ionizers (analytes with aliphatic amines) in dried blood spots. Recovery was generally highest in urine and lowest in blood. We also examined the effect of two experimental parameters on ion suppression and recovery: the spray solvent and the sample position (how far away from the paper tip the dried sample was spotted). Finally, the change in ion suppression and analyte elution as a function of time was examined by carrying out a paper spray analysis of dried plasma spots for 5 min by continually replenishing the spray solvent.
Public perception and risk communication in regard to bioterrorism against animals and plants.
Pearson, G S
2006-04-01
This paper examines the total international prohibition on the use of disease to attack humans, animals and plants, noting that in the past several countries had developed programmes for attacks on animals and plants as well as humans. Current activities undertaken by intergovernmental organisations - the World Health Organization (WHO), Food and Agricultural Organization (FAO) and World Organisation for Animal Health (OIE)--to counter the threat of attacks on humans, animals and plants are examined. Effective countermeasures to deliberate attacks need to be developed in harmony with existing measures to control natural or accidental outbreaks of disease. Finally the paper assesses the risk and the public perception of it, and considers what risk communication is needed and to whom. Clear mandates are needed for the FAO and OIE to be prepared to deal with outbreaks of disease, and with contamination of the food supply chain, whether accidental or intentional.

In the estimation of population value sets for health state classification systems such as the EuroQOL five dimensions questionnaire (EQ-5D), there is increasing interest in asking respondents to value their own health state, sometimes referred to as "experience-based utility values" or, more correctly, own rather than hypothetical health states. Own health state values differ to hypothetical health state values, and this may be attributable to many reasons. This paper critically examines whose values matter; why there is a difference between own and hypothetical values; how to measure own health state values; and why to use own health state values. Finally, the paper examines other ways that own health state values can be taken into account, such as including the use of informed general population preferences that may better take into account experience-based values.
Computer-assisted instruction: a library service for the community teaching hospital.
McCorkel, J; Cook, V
1986-04-01
This paper reports on five years of experience with computer-assisted instruction (CAI) at Winthrop-University Hospital, a major affiliate of the SUNY at Stony Brook School of Medicine. It compares CAI programs available from Ohio State University and Massachusetts General Hospital (accessed by telephone and modem), and software packages purchased from the Health Sciences Consortium (MED-CAPS) and Scientific American (DISCOTEST). The comparison documents one library's experience of the cost of these programs and the use made of them by medical students, house staff, and attending physicians. It describes the space allocated for necessary equipment, as well as the marketing of CAI. Finally, in view of the decision of the National Board of Medical Examiners to administer the Part III examination on computer (the so-called CBX) starting in 1988, the paper speculates on the future importance of CAI in the community teaching hospital.

This paper describes health and environmental impacts of coal-fired electric power plants. Effects on man, agriculture, and natural ecosystems are considered. These effects may result from direct impacts or exposures via air, water, and food chains. The paper is organized by geographical extent of effect. Occupational health impacts and local environmental effects such as noise and solid waste leachate are treated first. Then, regional effects of air pollution, including acid rain, are analyzed. Finally, potential global impacts are examined. Occupational health concerns considered include exposure to noise, dust, asbestos, mercury, and combustion products, and resulting injury and disease. Local effectsmore » considered include noise; air and water emissions of coal storage piles, solid waste operations, and cooling systems. Air pollution, once an acute local problem, is now a regional concern. Acute and chronic direct health effects are considered. Special attention is given to potential effects of radionuclides in coal and of acid rain. Finally, potential global impacts associated with carbon dioxide emissions are considered. 88 references, 9 tables.« less
The Problem of Whistleblowing in Engineering Ethics
NASA Astrophysics Data System (ADS)
Ohishi, Toshihiro
The purpose of this paper is to clarify the features of whistleblowing by considering the arguments about whistleblowing in engineering ethics. First, I analyze the concept of ‘whistleblowing’ by defining the word as clearly as possible. Second, I examine the standard justification theory of whistleblowing by showing the problems of the theory. Finally, I analyze the dilemma about whistleblowing by revealing a prospective whistleblower‧s struggle to choose moral value or non-moral value.
Perception for mobile robot navigation: A survey of the state of the art
NASA Technical Reports Server (NTRS)
Kortenkamp, David
1994-01-01
In order for mobile robots to navigate safely in unmapped and dynamic environments they must perceive their environment and decide on actions based on those perceptions. There are many different sensing modalities that can be used for mobile robot perception; the two most popular are ultrasonic sonar sensors and vision sensors. This paper examines the state-of-the-art in sensory-based mobile robot navigation. The first issue in mobile robot navigation is safety. This paper summarizes several competing sonar-based obstacle avoidance techniques and compares them. Another issue in mobile robot navigation is determining the robot's position and orientation (sometimes called the robot's pose) in the environment. This paper examines several different classes of vision-based approaches to pose determination. One class of approaches uses detailed, a prior models of the robot's environment. Another class of approaches triangulates using fixed, artificial landmarks. A third class of approaches builds maps using natural landmarks. Example implementations from each of these three classes are described and compared. Finally, the paper presents a completely implemented mobile robot system that integrates sonar-based obstacle avoidance with vision-based pose determination to perform a simple task.

Rock phosphate (RP) addition in cow-dung waste-paper mixtures at rates above 2% P has been reported to increase the rate of bio-transformation and humification of organic waste mixtures during vermicomposting to produce organic fertilizer for organic farming. However, the optimization of RP for vermicomposting was not established. The objective of this study was to determine the optimal amount of RP integration rates for effective bio-transformation of cow-dung waste-paper mixtures. Arrays of RP integration degrees (0, 0.5, 1, 1.5, 2, and 4% P as RP) were thoroughly mixed with cow- dung waste-paper mixtures to achieve an optimized C:N ratio of 30 and allowed to vermidegrade following the introduction of earthworms at a stocking mass of 12.5 g-worms kg -1 . The bio-transformation of the waste mixtures was examined by measuring C:N ratios and humification index (HI) and per cent ash and volatile solids. Application of 1% P as RP resulted in fast bio-transformation and maturation of cow-dung waste-paper mixtures. A scanning electron microscopy (SEM) was used to evaluate the morphological properties of the different vermicomposts affected by rates of RP showing the degree of degradation of initial compacted aggregates of cellulose and protein fibres in the mixtures at maturity. A germination test was used to further determine phytotoxicity of the final composts and microbial biomass assessment. The final vermicompost (organic fertilizer) had a C:N ratio of 7, MBC of 900 mg kg -1 and HI of 27.1%. The RP incorporation rate of 1% P of RP investigated is therefore, recommended for efficient vermidegradation and humification of cow-dung waste-paper mixtures. However, higher rates of RP incorporation should be considered where greater P enrichment of the final vermicompost (organic fertilizer) is desired.
Gay-Lussac Did Better Than He Knew

In his 1802 paper Joseph Louis Gay-Lussac reported the first definitive experimental evidence that many different gases exhibit the same fractional expansion of volume when heated. This property is known as Charles Law, Amontons Law, Dalton's Law, or the law of volumes. Gay-Lussac concluded from his experiments that many gases expand by 37.5% when heated from 0 ,oC to 100,oC. Although his result is within 2.5% of the modern value of 36.6% = 100/273.15, the discrepancy is surprising because his direct and simple experimental method allowed him to measure changes in volume with a precision of a few tenths of a percent. An examination of his original paper suggests, however, that he did not take into account that his measurements of the initial and final volumes of gas were made at slightly different pressures. With reasonable assumptions about the diagrams in his paper, one can use Pascal's law and the ideal gas law to correct the measured volumes so that they correspond to the same initial and final pressure. With this correction the results imply δV/V = .366. Gay-Lussac did better than he knew.
Work organization and ergonomics.
Carayon, P; Smith, M J
2000-12-01
This paper examines the impact of sociotechnical and business trends on work organization and ergonomics. This analysis is performed with the use of Balance Theory (Smith and Carayon-Sainfort, Int. J. Ind. Ergon. 1989, 4, 67-79). The impact on work organization and the work system of the following sociotechnical and business trends is discussed: re-structuring and re-organizing of companies, new forms of work organization, workforce diversity, and information and communication technology. An expansion of Balance Theory, from the design of work systems to the design of organizations, is discussed. Finally, the issue of change is examined. Several elements and methods are discussed for the design of change processes.
Cosmological immortality: how to eliminate aging on a universal scale.
Vidal, Clement
2014-01-01
The death of our universe is as certain as our individual death. Some cosmologists have elaborated models which would make the cosmos immortal. In this paper, I examine them as cosmological extrapolations of immortality narratives that civilizations have developed to face death anxiety. I first show why cosmological death should be a worry, then I briefly examine scenarios involving the notion of soul or resurrection on a cosmological scale. I discuss in how far an intelligent civilization could stay alive by engaging in stellar, galactic and universal rejuvenation. Finally, I argue that leaving a cosmological legacy via universe making is an inspiring and promising narrative to achieve cosmological immortality.
"A cool little buzz": alcohol intoxication in the dance club scene.
Hunt, Geoffrey; Moloney, Molly; Fazio, Adam
2014-06-01
In recent years, there has been increasing concern about youthful "binge" drinking and intoxication. Yet the meaning of intoxication remains under-theorized. This paper examines intoxication in a young adult nightlife scene, using data from a 2005-2008 National Institute on Drug Abuse-funded project on Asian American youth and nightlife. Analyzing in-depth qualitative interview data with 250 Asian American young adults in the San Francisco area, we examine their narratives about alcohol intoxication with respect to sociability, stress, and fun, and their navigation of the fine line between being "buzzed" and being "wasted." Finally, limitations of the study and directions for future research are noted.

Modern authorization systems span domains of administration, rely on many different authentication sources, and manage complex attributes as part of the authorization process. This . paper presents Cardea, a distributed system that facilitates dynamic access control, as a valuable piece of an inter-operable authorization framework. First, the authorization model employed in Cardea and its functionality goals are examined. Next, critical features of the system architecture and its handling of the authorization process are then examined. Then the S A M L and XACML standards, as incorporated into the system, are analyzed. Finally, the future directions of this project are outlined and connection points with general components of an authorization system are highlighted.
Clinical Ethics Consultation After God: Implications for Advocacy and Neutrality.
Parker, J Clint
2018-06-01
In After God: Morality and Bioethics in a Secular Age, H. Tristram Engelhardt, Jr. explores the broad implications for moral reasoning once a culture has lost a God's-eye perspective. In this paper, I focus on the implications of Engelhardt's views for clinical ethics consultation. I begin by examining the question of whether clinical ethics consultants (CECs) should advocate a particular viewpoint and/or process during consultations or adopt a neutral stance. I then examine the implications of Engelhardt's views for this question. Finally, I discuss some of Engelhardt's foundational ontological, metaphysical, meta-ethical, and epistemological commitments and how these commitments connect to his views on clinical ethics consultation.

Psychotherapy, psychoanalysis and urban poverty in Argentina.
Epele, Maria Esther
2016-12-01
Based on ethnographic research carried out in the Buenos Aires Metropolitan Area, this paper examines the views of social actors on the psychoanalytically-oriented psychotherapy focused on marginalized populations. From Foucault's perspective on the forms of truth-telling, the aim of this paper is to analyze, as a preliminary research report, treatments according to the native ways of speaking and listening, which dominate the description of therapeutic experiences of patients who come to the treatment without any professional intermediation. The neoliberal transformations of the past decades in Argentina changed both the landscape of the public health system and the daily lives of marginalized people. Considering such changes, this paper examines the ways in which verbal actions (speaking and listening) take place in psychotherapy and mark the course not only of treatments but also the temporal rhythms of their development, and their various levels of efficacy. Finally, the discussion focuses on how ways of speaking and listening in treatments are modeled not only by institutional dynamics but also by the characteristics these verbal activities take in everyday life under the logics of power that prevail over them.
Integrating National Space Visions

Sherwood, Brent
2006-01-01
This paper examines value proposition assumptions for various models nations may use to justify, shape, and guide their space programs. Nations organize major societal investments like space programs to actualize national visions represented by leaders as investments in the public good. The paper defines nine 'vision drivers' that circumscribe the motivations evidently underpinning national space programs. It then describes 19 fundamental space activity objectives (eight extant and eleven prospective) that nations already do or could in the future use to actualize the visions they select. Finally the paper presents four contrasting models of engagement among nations, and compares these models to assess realistic pounds on the pace of human progress in space over the coming decades. The conclusion is that orthogonal engagement, albeit unlikely because it is unprecedented, would yield the most robust and rapid global progress.

This paper examines the way the planning education is taught and examines the recent trends in the curricula of planning education institutions. The introduction of changing economic systems and planning in the field of education is discussed against these changes. Additionally, the evolution in the planner’s role and how it affects the planning education is discussed. The paper is addressing trends and challenges the countries and their planning changes are facing in 21st century. The trends such as increasing globalization, fuzziness of spatial structures and their borders, complexity and uncertainty and the growing interconnectedness of the world are discussed. Another aim is to prepare a common ground, a platform at the university level for scientific cooperation in the field of planning. This study aims at examining the situation of planning in the contemporary world. The identified challenges include the need for more flexibility in planning and planning education, the emergence of innovations and creativity in planners and planning projects, the necessity of promoting soft skills while keeping the existing technical nature of planning and lastly, the need for more interdisciplinary work. The final part of the paper is discussing the future planning education and recommendations on how the schools of planning should reflect these changes.
Advance directives in the UK: legal, ethical, and practical considerations for doctors.
Kessel, A S; Meran, J
1998-05-01
In the United Kingdom (UK), advance directives have recently received considerable attention from professional and voluntary organizations as well as medical journals and the media. However, despite such exposure, many doctors remain uncertain of the importance or relevance of advance directives with regard to their own clinical practice. This paper addresses these uncertainties by first explaining what advance directives are and then describing the current legal status of such directives in the UK. Examination of the cases underpinning this status reveals several key elements: competence, information, anticipation, applicability, and freedom from duress. Each is discussed. Although this paper focuses on legal issues, it is important that medical law does not dominate medical ethics. Accordingly, the paper also discusses some important philosophical and sociological considerations that have remained largely unexplored in the medical press. Finally, the paper deals with practical matters, including how the general practitioner might be involved.

In this paper we present a comprehensive and detailed study of Interatomic Coulombic Decay (ICD) occurring after irradiating argon dimers with XUV-synchrotron radiation. A manifold of different decay channels is observed and the corresponding initial and final states are assigned. Additionally, the effect of nuclear dynamics on the ICD electron spectrum is examined for one specific decay channel. The internuclear distance-dependent width Γ(R) of the decay is obtained from the measured kinetic energy release distribution of the ions employing a classical nuclear dynamics model.

Is a clinical sociolinguistics possible?
Ball, M J
1992-01-01
This paper considers the idea of developing a clinical sociolinguistics. Various areas of the field are examined, and the importance of the 'core' area of the correlation of non-linguistic variables with linguistic variables stressed. Issues concerning language and class, region, sex, age and context of utterance are investigated, together with the implications for clinical linguistics. Finally, the difficulty of integrating such issues into clinical assessment is explored, and a tentative step forward suggested along the lines of a 'clinical sociolinguistic checklist'.
POLICY VARIATION, LABOR SUPPLY ELASTICITIES, AND A STRUCTURAL MODEL OF RETIREMENT
MANOLI, DAY; MULLEN, KATHLEEN J.; WAGNER, MATHIS
2015-01-01
This paper exploits a combination of policy variation from multiple pension reforms in Austria and administrative data from the Austrian Social Security Database. Using the policy changes for identification, we estimate social security wealth and accrual elasticities in individuals’ retirement decisions. Next, we use these elasticities to estimate a dynamic programming model of retirement decisions. Finally, we use the estimated model to examine the labor supply and welfare consequences of potential social security reforms. PMID:26472916

In this paper, the actuarial method of multiple decrement life table analysis of censored, longitudinal data is examined. The discussion is organized in terms of the first segment of usage of an intrauterine device. Weaknesses of the actuarial approach are pointed out, and an alternative approach, based on the classical model of competing risks, is proposed. Finally, the actuarial and the alternative method of analyzing censored data are compared, using data from the Taichung Medical Study on Intrauterine Devices.

Championing mental health at work: emerging practice from innovative projects in the UK.
Robinson, Mark; Tilford, Sylvia; Branney, Peter; Kinsella, Karina
2014-09-01
This paper examines the value of participatory approaches within interventions aimed at promoting mental health and wellbeing in the workplace. Specifically the paper explores data from the thematic evaluation of the Mental Health and Employment project strand within the Altogether Better programme being implemented in England in the Yorkshire and Humber region, which was funded through the BIG Lottery and aimed to empower people across the region to lead better lives. The evaluation combined a systematic evidence review with semi-structured interviews across mental health and employment projects. Drawing on both evaluation elements, the paper examines the potential of workplace-based 'business champions' to facilitate organizational culture change within enterprises within a deprived regional socio-economic environment. First, the paper identifies key policy drivers for interventions around mental health and employment, summarizes evidence review findings and describes the range of activities within three projects. The role of the 'business champion' emerged as crucial to these interventions and therefore, secondly, the paper examines how champions' potential to make a difference depends on the work settings and their existing roles, skills and motivation. In particular, champions can proactively coordinate project strands, embed the project, encourage participation, raise awareness, encourage changes to work procedures and strengthen networks and partnerships. The paper explores how these processes can facilitate changes in organizational culture. Challenges of implementation are identified, including achieving leverage with senior management, handover of ownership to fellow employees, assessing impact and sustainability. Finally, implications for policy and practice are discussed, and conclusions drawn concerning the roles of champions within different workplace environments. © The Author (2013).

"The purpose of this paper is to describe and comment on the labor force movements in the Middle East with particular reference to the implications of these flows for the process of urbanization in the region. [The author deals] with both international transfers of labor and internal movements of labor to urban communities." The international flow of labor in the Middle East in general is first examined, and a classification scheme is outlined to identify the major differences that exist within the region. Internal labor force migration is then analyzed using data for Libya. The final sections of the paper deal with data collection and policy issues. excerpt
Playing the game: sports as a force for promoting improved academic performance for urban youth.
DeMeulenaere, Eric
2010-01-01
Using qualitative research methods involving observations and interviews with four students, their families and friends, this paper examines six ways that student involvement in sports promoted student success: structuring schedules, creating incentives, building confidence, developing positive adult and peer role models, and its role in getting students to develop future aspirations. It then turns to consider how students use their involvement with sports to negotiate the challenges they faced in adopting a successful student identity. Participation in school sports became a powerful justification for successful school performance for the participating students in this study. Finally, this paper ends with several policy implications for considering sports programming in urban schools.

This White Paper examines the current state of Hypersonic Airbreathing Propulsion at the NASA Langley Research Center and the factors influencing this area of work and its personnel. Using this knowledge, the paper explores beyond the present day and suggests future directions and strategies for the field. Broad views are first taken regarding potential missions and applications of hypersonic propulsion. Then, candidate propulsion systems that may be applicable to these missions are suggested and discussed. Design tools and experimental techniques for developing these propulsion systems are then described, and approaches for applying them in the design process are considered. In each case, current strategies are reviewed and future approaches that may improve the techniques are considered. Finally, the paper concentrates on the needs to be addressed in each of these areas to take advantage of the opportunities that lay ahead for both the NASA Langley Research Center and the Aerodynamic Aerothermodynamic, and Aeroacoustics Competency. Recommendations are then provided so that the goals set forth in the paper may be achieved.
Protecting civil aircraft from the MANPAD threat: is this a practical scenario?
NASA Astrophysics Data System (ADS)
Taylor, William
2005-11-01
This paper has been written as a key note address and backdrop to the 2005 SPIE Technologies for Optical Countermeasures II Conference. The paper uses as a topic the problem of protecting civil aircraft from the Man Portable Air Defence missile Systems (MANPADS). The paper examines the economic background of the airline industry and the effects such a successful attack could have. It then addresses the various motives, means, and opportunities that the terrorists have to use MANPADS to progress attacks against civil aircraft. In reviewing the various mitigation options available to defeat or deny MANPAD engagements, the paper identifies key technology areas available for exploitation. It then focuses on the optical countermeasure technologies used in providing aircraft platform self protection. Finally, the paper summarises and concludes that whilst a lot has and can be done to militate against the MANPAD threat there is not yet an exportable, affordable and robust countermeasures technology for large scale commercial systems and operations.

The physical examination of patients is an important diagnostic competence, but little is known about the examination skills of final-year medical students. To investigate physical examination skills of final-year medical students. In a cross-sectional study, 40 final-year students were asked to perform a detailed physical examination on standardized patients. Their performances were video-recorded and rated by independent video assessors. Video ratings showed a mean success rate of 40.1 % (SD 8.2). As regards accompanying doctor-patient communication, final-year students achieved a mean of no more than 36.7 % (SD 8.9) in the appropriate use of the corresponding communication items. Our study revealed severe deficits among final-year medical students in performing a detailed physical examination on a standardized patient. Thus, physical examination skills training should aim to improve these deficits while also paying attention to communicative aspects. Copyright © 2015. Published by Elsevier GmbH.

Background As part of the Harvard Cancer Prevention Program Project, we sought to address disparities reflected in social class and race/ethnicity by developing and testing a behavioral intervention model that targeted fruit and vegetable consumption, red meat consumption, multivitamin intake, and physical activity in working-class, multiethnic populations. Methods This paper examined the associations between change in leisure-time physical activity and individual and social contextual factors in participants employed in small businesses (n = 850) at both baseline and at 18-month final. Results In bivariate analyses, age, language acculturation, social ties, and workplace social capital were significantly associated with physical activity at final. In multivariable analyses, being younger and having high language acculturation were significantly associated with greater leisuretime physical activity at final; high workplace social capital was significantly associated with a decline in physical activity at final. Conclusion These findings have implications for understanding factors that are integral to promoting change in physical activity among working-class, multiethnic populations. PMID:22806257
Experiencing Madness: Mental Patients in Medieval Arabo-Islamic Medicine.
Koetschet, Pauline
2016-01-01
This paper focuses on the mental patients in Arabo-Islamic Middle Ages. Patients suffering from mental illnesses generated a lot of interest for Arabo-Islamic physicians. The first objective of this study is to identify who were the mentally infirm and to compare the Arab physicians' typologies of mental patients to that of their Greek predecessors. The second part of this paper shifts the focus from theoretical descriptions to case histories and biographical sources, in order to understand how the physicians treated their mental patients, and to find out what was the social impact of this medical approach. Finally, because the special provision for the insane is a distinctive feature of the Islamic hospital, the third part of my paper examines whether the main purpose of these hospitals was the patients' confinement or their treatment.

By examining the role of digital tools and social media, this paper discusses an innovative prospective research study to enhance social inclusion of young adults with intellectual disabilities (ID). The paper begins with an overview of how individuals with disabilities have historically been excluded from society based on limited access and minimal opportunities afforded to them. Next, the paper presents the caveats that may hinder the improvement of social inclusion of young adults with ID and the oversights when developing digital technologies. Details about a prospective intervention research study are described that include a mobile application and a social media component. Finally, implications for research and practice are highlighted to emphasize the fundamental call for an insightful deliberation of these caveats that needs to be addressed in the design of a research study of this nature.

Hayward, Vincent; Hayati, Samad
1987-01-01
The paper describes the design of a controller for cooperative robots being designed at McGill University in a collaborative effort with the Jet Propulsion Laboratory. The first part of the paper discusses the background and motivation for multiple arm control. Then, a set of programming primitives, which are based on the RCCL system and which permit a programmer to specify cooperative tasks are described. The first group of primitives are motion primitives which specify asynchronous motions, master/slave motions, and cooperative motions. In the context of cooperative robots, trajectory generation issues will be discussed and the implementation described. A second set of primitives provides for the specification of spatial relationships. The relations between programming and control in the case of multiple robot are examined. Finally, the paper describes the allocation of various tasks among a set of microprocessors sharing a common bus.
An extensive literature review of the evaluation of HIV prevention programmes.
Coleman, L M; Ford, N J
1996-09-01
This paper draws out and distils three key themes that have emerged from a substantial bibliographical review of a range of HIV intervention programmes, implemented throughout the world between years 1987 and 1995. Specifically, the paper assesses (1) to what extent intervention programmes have been tailored to meet the requirements and needs of specific target groups; (2) to what extent intervention programmes are supported by social and psychological theory of attitudinal and behavioural change, and also to what extent the results and findings from the interventions have amended existing theory; and, finally, (3) the range of methodologies employed in evaluating intervention programmes and also to what extent behavioural measures have been used in examining a programme's effectiveness. In light of these themes, the paper presents and discusses the principal factors thought to contribute towards the effectiveness of HIV intervention programmes.
High-frequency neural oscillations and visual processing deficits in schizophrenia
Tan, Heng-Ru May; Lana, Luiz; Uhlhaas, Peter J.
2013-01-01
Visual information is fundamental to how we understand our environment, make predictions, and interact with others. Recent research has underscored the importance of visuo-perceptual dysfunctions for cognitive deficits and pathophysiological processes in schizophrenia. In the current paper, we review evidence for the relevance of high frequency (beta/gamma) oscillations towards visuo-perceptual dysfunctions in schizophrenia. In the first part of the paper, we examine the relationship between beta/gamma band oscillations and visual processing during normal brain functioning. We then summarize EEG/MEG-studies which demonstrate reduced amplitude and synchrony of high-frequency activity during visual stimulation in schizophrenia. In the final part of the paper, we identify neurobiological correlates as well as offer perspectives for future research to stimulate further inquiry into the role of high-frequency oscillations in visual processing impairments in the disorder.

Concussion from sport is increasingly recognized as a public health priority. In response, all states and the District of Columbia have enacted youth concussion legislation. This paper first examines key developments in concussion-related policy and legislation and then uses the findings from recent scientific studies to highlight the need to incorporate evolving scientific evidence into concussion legislation in order to better protect youth and adolescent athletes. Next, the paper discusses the framework of empirical health law research and why it should be applied in the case of concussion legislation. Finally, this paper argues that empirical health law research should be considered in any decision about whether legislation can help improve the health and safety of young players, a particularly vulnerable population whose unique needs have not yet been adequately addressed.
Stochastic quantization and holographic Wilsonian renormalization group of free massive fermion
NASA Astrophysics Data System (ADS)
Moon, Sung Pil
2018-06-01
We examine a suggested relation between stochastic quantization and the holographic Wilsonian renormalization group in the massive fermion case on Euclidean AdS space. The original suggestion about the general relation between the two theories is posted in arXiv:1209.2242. In the previous researches, it is already verified that scalar fields, U(1) gauge fields, and massless fermions are consistent with the relation. In this paper, we examine the relation in the massive fermion case. Contrary to the other case, in the massive fermion case, the action needs particular boundary terms to satisfy boundary conditions. We finally confirm that the proposed suggestion is also valid in the massive fermion case.
Pulling up the runaway: the effect of new evidence on euthanasia's slippery slope.
Ryan, C J
1998-10-01
The slippery slope argument has been the mainstay of many of those opposed to the legalisation of physician-assisted suicide and euthanasia. In this paper I re-examine the slippery slope in the light of two recent studies that examined the prevalence of medical decisions concerning the end of life in the Netherlands and in Australia. I argue that these two studies have robbed the slippery slope of the source of its power--its intuitive obviousness. Finally I propose that, contrary to the warnings of the slippery slope, the available evidence suggests that the legalisation of physician-assisted suicide might actually decrease the prevalence of non-voluntary and involuntary euthanasia.

Exorcism: a psychiatric viewpoint.
Trethowan, W. H.
1976-01-01
Doctors, for several reasons, should be concerned with exorcism is the view of Professor Trethowan, who in this paper, looks at the main features of exorcism as practised in the middle ages and now appearing in the modern world, as was seen in the recent Ossett case in Britain. He examines in some detail the nature of supposed demoniacal possession and describes its symptoms and signs. He also touches on the social, as opposed to the religious, background in which demoniacal possession flourished (not lacking in the world today), so leading to an examination of the psychodynamic aspects of demoniacal possession and the question of absolute evil. Finally he compares the techniques of exorcism and of modern psychiatric practice. PMID:966260
Prosocial Involvement as a Positive Youth Development Construct: A Conceptual Review
Lam, Ching Man
2012-01-01
This paper discusses the concept of prosocial involvement as a positive youth development construct. How prosocial involvement is defined and how the different theories conceptualize prosocial involvement are reviewed. Antecedents of prosocial involvement such as biological traits, personality, cognitive and emotional processes, socialization experience, culture, and their social context are examined. The relationship between prosocial involvement and adolescent developmental outcomes, together with strategies to promote prosocial involvement in adolescents, are discussed. Finally, directions for future research and practice are proposed. PMID:22649323

This study examines the problem of dissipative synchronisation of coupled reaction-diffusion neural networks with time-varying delays. This paper proposes a complex dynamical network consisting of N linearly and diffusively coupled identical reaction-diffusion neural networks. By constructing a suitable Lyapunov-Krasovskii functional (LKF), utilisation of Jensen's inequality and reciprocally convex combination (RCC) approach, strictly ?-dissipative conditions of the addressed systems are derived. Finally, a numerical example is given to show the effectiveness of the theoretical results.

Willers, Ian
This paper examines some activities in High Energy Physics that utilise parallel computing. The topic includes all computing from the proposed SIMD front end detectors, the farming applications, high-powered RISC processors and the large machines in the computer centers. We start by looking at the motivation behind using parallelism for general purpose computing. The developments around farming are then described from its simplest form to the more complex system in Fermilab. Finally, there is a list of some developments that are happening close to the experiments.

Systems Issues In Terrestrial Fiber Optic Link Reliability

Spencer, James L.; Lewin, Barry R.; Lee, T. Frank S.
1990-01-01
This paper reviews fiber optic system reliability issues from three different viewpoints - availability, operating environment, and evolving technologies. Present availability objectives for interoffice links and for the distribution loop must be re-examined for applications such as the Synchronous Optical Network (SONET), Fiber-to-the-Home (FTTH), and analog services. The hostile operating environments of emerging applications (such as FTTH) must be carefully considered in system design as well as reliability assessments. Finally, evolving technologies might require the development of new reliability testing strategies.
Quantum Properties of the Superposition of Two Nearly Identical Coherent States
NASA Astrophysics Data System (ADS)
Othman, Anas; Yevick, David
2018-04-01
In this paper, we examine the properties of the state obtained when two nearly identical coherent states are superimposed. We found that this state exhibits many nonclassical properties such as sub-Poissonian statistics, squeezing and a partially negative Wigner function. These and other properties indicate that such states, here termed near coherent states, are significantly closer to coherent states more than the generalized Schrördinger cat states. We finally provide an experimental procedure for generating the near coherent states.

Wu, Zheng; Yin, George; Lei, Dongxia
2018-09-01
This paper focuses on a class of generalized Ginzburg-Landau equations with random switching. In our formulation, the nonlinear term is allowed to have higher polynomial growth rate than the usual cubic polynomials. The random switching is modeled by a continuous-time Markov chain with a finite state space. First, an explicit solution is obtained. Then properties such as stochastic-ultimate boundedness and permanence of the solution processes are investigated. Finally, two-time-scale models are examined leading to a reduction of complexity.

In this paper, we propose a full characterization of a generalized q-deformed Tamm-Dancoff oscillator algebra and investigate its main mathematical and physical properties. Specifically, we study its various representations and find the condition satisfied by the deformed q-number to define the algebra structure function. Particular Fock spaces involving finite and infinite dimensions are examined. A deformed calculus is performed as well as a coordinate realization for this algebra. A relevant example is exhibited. Associated coherent states are constructed. Finally, some thermodynamics aspects are computed and discussed.
Resilience as a Positive Youth Development Construct: A Conceptual Review
Lee, Tak Yan; Cheung, Chau Kiu; Kwong, Wai Man
2012-01-01
The concept of resilience is reviewed from a range of disciplinary perspectives in this paper. Both broad and narrow definitions of resilience are highlighted and a working definition of resilience is proposed to inform research, policy and practice. Different psychological, social and ecological protective factors, particularly competence, optimism, and bonding to family and cultural beliefs are highlighted. Theoretical relationships between resilience and positive youth development are examined with an attempt to erase misunderstandings. Finally, how schools can promote resilience among students is discussed. PMID:22623893
The interface between population and development models, plans and policies.
Cohen, S I
1989-01-01
Scant attention has been given to integrating policy issues in population economics and development economics into more general frameworks. Reviewing the state of the art, this paper examines problems in incorporating population economics variables in development planning. Specifically, conceptual issues in defining population economics variables, modelling relationships between them, and operationalizing frameworks for decision making are explored with hopes of yielding tentative solutions. Several controversial policy issues affecting the development process are also examined in the closing section. 2 of these issues would be the social efficiency of interventions with fertility, and of resource allocations to human development. The effective combination between agriculture and industry in promoting and equitably distributing income growth among earning population groups is a 3rd issue of consideration. Finally, the paper looks at the optimal combination between transfer payments and provisions in kind in guaranteeing minimum consumption needs for poverty groups. Overall, the paper finds significant obstacles to refining the integration of population economics and development policy. Namely, integrating time and place dimensions in classifying people by activity, operationalizing population economics variable models to meet the practical situations of planning and programs, and assessing conflicts and complementarities between alternative policies pose problems. 2 scholarly comments follow the main body of the paper.

Within the framework of MIT's course 1.00: Introduction to Computers and Engineering Problem Solving, this paper describes an innovative project entitled: Studio 1.00 that integrates lectures with in-class demonstrations, active learning sessions, and on-task feedback, through the use of wireless laptop computers. This paper also describes a related evaluation study that investigated the effectiveness of different instructional strategies, comparing traditional teaching with two models of the studio format. Students' learning outcomes, specifically, their final grades and conceptual understanding of computational methods and programming, were examined. Findings indicated that Studio-1.00, in both its extensive- and partial-active learning modes, enhanced students' learning outcomes in Java programming. Comparing to the traditional courses, more students in the studio courses received "A" as their final grade and less failed. Moreover, students who regularly attended the active learning sessions were able to conceptualize programming principles better than their peers. We have also found two weaknesses in the teaching format of Studio-1.00 that can guide future versions of the course.

This paper examines the international exchange in surgery in the decades before World War I, a period of growing globalization in communication and transport. Focusing on Europe and North America, it looks first at the various means of exchange, especially surgical travel and the culture emerging around it and follows specific directions of exchange, from France and Britain, first to the German-speaking countries and finally to North America. Subsequently, the account turns to international organizations as an important means of exchange in this time period. The International Society of Surgery, in particular, provided a forum for a vivid internationalist discourse, which, however, stood in tension with simultaneous nationalist tendencies leading up to World War I. The paper finally discusses how the international exchange and communication at the time can be seen as an instance of modern surgeons claiming—and simultaneously trying to create—the global universality of surgical knowledge and practices, making sure that surgery is the same the world over.

This paper describes the methodology followed by the French Atomic Energy Commission (CEA) to decommission the buildings of former research facilities for demolition or possible reuse. It is a well known fact that the French nuclear safety authority has decided not to define any general release level for the decommissioning of nuclear facilities, thus effectively prohibiting radiological measurement-driven decommissioning. The decommissioning procedure therefore requires an intensive in-depth examination of each nuclear plant. This requires a good knowledge of the past history of the plant, and should be initiated as early as possible. The paper first describes the regulatory framework recentlymore » unveiled by the French Safety Authority, then, reviews its application to ongoing decommissioning projects. The cornerstone of the strategy is the definition of waste zoning in the buildings to segregate areas producing conventional waste from those generating nuclear waste. After dismantling, suitable measurements are carried out to confirm the conventional state of the remaining walls. This requires low-level measurement methods providing a suitable detection limit within an acceptable measuring time. Although this generally involves particle counting and in-situ low level gamma spectrometry, the paper focuses on y spectrometry. Finally, the lessons learned from ongoing projects are discussed.

Using a Cultural and RDoC Framework to Conceptualize Anxiety in Asian Americans
Liu, Huiting; Lieberman, Lynne; Stevens, Elizabeth; Auerbach, Randy P.; Shankman, Stewart A.
2016-01-01
Asian Americans are one of the fastest growing minority group in the United States; however, mental health within this population segment, particularly anxiety disorders, remains significantly understudied. Both the heterogeneity within the Asian American population, along with the multidimensional nature of anxiety, contribute to difficulties in understanding anxiety in this population. The present paper will review two sources of heterogeneity within anxiety in Asian Americans: (1) cultural variables and (2) mechanisms or components of anxiety. Specifically, we will examine four cultural variables most commonly found in research related to anxiety in Asian Americans: acculturation, affect valuation, loss of face, and individualism-collectivism. We will also discuss ways to parse anxiety through a Research Domain Criteria (RDoC) framework, specifically focusing on sensitivity to acute and potential threat, constructs within the Negative Valence System. We also present previously unpublished preliminary data to illustrate one way of examining ethnic differences in anxiety using an RDoC framework. Finally, this paper offers recommendations for future work in this area. PMID:27659553
Balancing liberation and protection: a moderate approach to adolescent health care decision-making.
Piker, Andy
2011-05-01
In this paper I examine the debate between 'protectionists' and 'liberationists' concerning the appropriate role of minors in decision-making about their health care, focusing particularly on disagreements between the two sides regarding adolescents. Protectionists advocate a more traditional, paternalistic approach in which minors have relatively little input into the healthcare decision-making process, and decisions are made for them by parents or other adults, guided by a commitment to the patient's best interests. Liberationists, on the other hand, argue in favour of expanded participation by minors in treatment decisions, and decision-making authority for at least some adolescents. My examination of the debate includes discussion of liberationist shifts that have taken place in the medical community as well as in legal policy and practice, and consideration of recent research on adolescent development. In the final section of the paper, I propose a moderate position that addresses both liberationist and protectionist concerns. © 2009 Blackwell Publishing Ltd.

The developed states will be able to finalize the struggles they have entered with a minimum of human casualties and minimum cost thanks to high-tech. Considering the increasing number of world economic problems, the development of human rights and humanitarian law it is easy to understand the importance of minimum cost and minimum loss of human. In this paper, cyber warfare and electronic warfare concepts are examined in conjunction with the historical development and the relationship between them is explained. Finally, assessments were carried out about the use of cyber electronic warfare in the coming years.
An examination of the concept of driving point receptance
NASA Astrophysics Data System (ADS)
Sheng, X.; He, Y.; Zhong, T.
2018-04-01
In the field of vibration, driving point receptance is a well-established and widely applied concept. However, as demonstrated in this paper, when a driving point receptance is calculated using the finite element (FE) method with solid elements, it does not converge as the FE mesh becomes finer, suggesting that there is a singularity. Hence, the concept of driving point receptance deserves a rigorous examination. In this paper, it is firstly shown that, for a point harmonic force applied on the surface of an elastic half-space, the Boussinesq formula can be applied to calculate the displacement amplitude of the surface if the response point is sufficiently close to the load. Secondly, by applying the Betti reciprocal theorem, it is shown that the displacement of an elastic body near a point harmonic force can be decomposed into two parts, with the first one being the displacement of an elastic half-space. This decomposition is useful, since it provides a solid basis for the introduction of a contact spring between a wheel and a rail in interaction. However, according to the Boussinesq formula, this decomposition also leads to the conclusion that a driving point receptance is infinite (singular), and would be undefinable. Nevertheless, driving point receptances have been calculated using different methods. Since the singularity identified in this paper was not appreciated, no account was given to the singularity in these calculations. Thus, the validity of these calculation methods must be examined. This constructs the third part of the paper. As the final development of the paper, the above decomposition is utilised to define and determine driving point receptances required for dealing with wheel/rail interactions.
Health and Wellness Technology Use by Historically Underserved Health Consumers: Systematic Review
Perchonok, Jennifer
2012-01-01
Background The implementation of health technology is a national priority in the United States and widely discussed in the literature. However, literature about the use of this technology by historically underserved populations is limited. Information on culturally informed health and wellness technology and the use of these technologies to reduce health disparities facing historically underserved populations in the United States is sparse in the literature. Objective To examine ways in which technology is being used by historically underserved populations to decrease health disparities through facilitating or improving health care access and health and wellness outcomes. Methods We conducted a systematic review in four library databases (PubMed, PsycINFO, Web of Science, and Engineering Village) to investigate the use of technology by historically underserved populations. Search strings consisted of three topics (eg, technology, historically underserved populations, and health). Results A total of 424 search phrases applied in the four databases returned 16,108 papers. After review, 125 papers met the selection criteria. Within the selected papers, 30 types of technology, 19 historically underserved groups, and 23 health issues were discussed. Further, almost half of the papers (62 papers) examined the use of technology to create effective and culturally informed interventions or educational tools. Finally, 12 evaluation techniques were used to assess the technology. Conclusions While the reviewed studies show how technology can be used to positively affect the health of historically underserved populations, the technology must be tailored toward the intended population, as personally relevant and contextually situated health technology is more likely than broader technology to create behavior changes. Social media, cell phones, and videotapes are types of technology that should be used more often in the future. Further, culturally informed health information technology should be used more for chronic diseases and disease management, as it is an innovative way to provide holistic care and reminders to otherwise underserved populations. Additionally, design processes should be stated regularly so that best practices can be created. Finally, the evaluation process should be standardized to create a benchmark for culturally informed health information technology. PMID:22652979

This paper is centered on getting students to understand the nature of science (NOS) by considering historical material in relation to modern philosophers of science. This paper incorporates the methodology of contrasting cases in the calculus-based introductory physics course on optics and modern physics. Students study one philosopher all semester as a group project and report regularly on how their philosopher would view the subject matter of the course. Almost all of the students were able to argue successfully on the final examination about all three philosophers. Students become aware that the same textual material can be viewed in a variety of ways. The answers that students give about the NOS have become clearer at the end of the course.
Influence of pore structure on compressive strength of cement mortar.
Zhao, Haitao; Xiao, Qi; Huang, Donghui; Zhang, Shiping
2014-01-01
This paper describes an experimental investigation into the pore structure of cement mortar using mercury porosimeter. Ordinary Portland cement, manufactured sand, and natural sand were used. The porosity of the manufactured sand mortar is higher than that of natural sand at the same mix proportion; on the contrary, the probable pore size and threshold radius of manufactured sand mortar are finer. Besides, the probable pore size and threshold radius increased with increasing water to cement ratio and sand to cement ratio. In addition, the existing models of pore size distribution of cement-based materials have been reviewed and compared with test results in this paper. Finally, the extended Bhattacharjee model was built to examine the relationship between compressive strength and pore structure.

This paper reviews the literature on smoking cessation interventions, with a focus on the last twenty years (1991 to 2010). These two decades witnessed major development in a wide range of cessation interventions, from pharmacotherapy to tobacco price increases. It was expected that these interventions would work conjointly to increase the cessation rate on the population level. This paper examines population data from the U.S., from 1991 to 2010, using the National Health Interview Surveys. Results indicate there is no consistent trend of increase in the population cessation rate over the last two decades. Various explanations are presented for this lack of improvement, and the key concept of Impact = Effectiveness × Reach is critically examined. Finally, it suggests that the field of cessation has focused so much on developing and promoting interventions to improve smokers’ odds of success that it has largely neglected to investigate how to get more smokers to try to quit and to try more frequently. Future research should examine whether increasing the rate of quit attempts would be key to improving the population cessation rate. PMID:22345233
When integration fails: Prokaryote phylogeny and the tree of life.
O'Malley, Maureen A
2013-12-01
Much is being written these days about integration, its desirability and even its necessity when complex research problems are to be addressed. Seldom, however, do we hear much about the failure of such efforts. Because integration is an ongoing activity rather than a final achievement, and because today's literature about integration consists mostly of manifesto statements rather than precise descriptions, an examination of unsuccessful integration could be illuminating to understand better how it works. This paper will examine the case of prokaryote phylogeny and its apparent failure to achieve integration within broader tree-of-life accounts of evolutionary history (often called 'universal phylogeny'). Despite the fact that integrated databases exist of molecules pertinent to the phylogenetic reconstruction of all lineages of life, and even though the same methods can be used to construct phylogenies wherever the organisms fall on the tree of life, prokaryote phylogeny remains at best only partly integrated within tree-of-life efforts. I will examine why integration does not occur, compare it with integrative practices in animal and other eukaryote phylogeny, and reflect on whether there might be different expectations of what integration should achieve. Finally, I will draw some general conclusions about integration and its function as a 'meta-heuristic' in the normative commitments guiding scientific practice. Copyright © 2012 Elsevier Ltd.

A systematic review examining the effectiveness of blending technology with team-based learning.
River, Jo; Currie, Jane; Crawford, Tonia; Betihavas, Vasiliki; Randall, Sue
2016-10-01
Technological advancements are rapidly changing nursing education in higher education settings. Nursing academics are enthusiastically blending technology with active learning approaches such as Team Based Learning (TBL). While the educational outcomes of TBL are well documented, the value of blending technology with TBL (blended-TBL) remains unclear. This paper presents a systematic review examining the effectiveness of blended-TBL in higher education health disciplines. This paper aimed to identify how technology has been incorporated into TBL in higher education health disciplines. It also sought to evaluate the educational outcomes of blended-TBL in terms of student learning and preference. A review of TBL research in Medline, CINAHL, ERIC and Embase databases was undertaken including the search terms, team based learning, nursing, health science, medical, pharmaceutical, allied health education and allied health education. Papers were appraised using the Critical Appraisal Skills Program (CASP). The final review included 9 papers involving 2094 student participants. A variety of technologies were blended with TBL including interactive eLearning and social media. There is limited evidence that blended-TBL improved student learning outcomes or student preference. Enthusiasm to blend technology with TBL may not be as well founded as initially thought. However, few studies explicitly examined the value of incorporating technology into TBL. There is a clear need for research that can discern the impact of technology into TBL on student preference and learning outcomes, with a particular focus on barriers to student participation with online learning components.

Sziroczak, D.; Smith, H.
2016-07-01
This paper provides an overview of the current technical issues and challenges associated with the design of hypersonic vehicles. Two distinct classes of vehicles are reviewed; Hypersonic Transports and Space Launchers, their common features and differences are examined. After a brief historical overview, the paper takes a multi-disciplinary approach to these vehicles, discusses various design aspects, and technical challenges. Operational issues are explored, including mission profiles, current and predicted markets, in addition to environmental effects and human factors. Technological issues are also reviewed, focusing on the three major challenge areas associated with these vehicles: aerothermodynamics, propulsion, and structures. In addition, matters of reliability and maintainability are also presented. The paper also reviews the certification and flight testing of these vehicles from a global perspective. Finally the current stakeholders in the field of hypersonic flight are presented, summarizing the active programs and promising concepts.
Energy Justice and the Stakeholders Involved: A Case Study of Solar Power in Rural Haiti
NASA Astrophysics Data System (ADS)
Romulus, Elijah Rey Asse
This paper explores and analyzes energy justice and the stakeholders involved. Energy insecurity, specifically the lack of access to electricity effects over 1.3 billion people worldwide and energy justice is a way to address it. This paper is supported by a case study with data collected in the southern rural regions of Haiti regarding energy justice communities. Three cities were studied: Les Cayes, Anse-a-Veau, and Les Anglais. It examines how solar businesses can aid energy justice communities seeking access to electricity. Stakeholders such as the communities themselves, solar businesses, and nonprofits in the region are studied and analyzed. The paper concludes solar businesses are helping said communities but needs participation from other stakeholders to be successful. Finally, there are five recommendations to build capacity, develop infrastructure in the region, explore the possibility of solar cooperatives, strengthen the solar economy in Haiti, and demand reparations.
Facing the Language-Memory Problem in the Study of Autobiographical Memory.
Bartoli, Eleonora; Smorti, Andrea
2018-05-16
This paper discusses the problem of the role of language in autobiographical memory, that is barely considered in studies on autobiographical memories and narratives. As a matter of fact, most of the current studies on autobiographical memory confounded memory and narrative together. The present paper focuses on two main issues. Firstly, it debates how narratives contribute to the construction of autobiographical memories through self-other communication. Secondly, it reflects on how language and communication should be manipulated in studies about autobiographical memory. This paper is made of three sections: the first section discusses the role of language, particularly in the form of narrative, as a social tool by which autobiographical memories can be organised in a life story; the second section examines previous methods of investigation used in the study of autobiographical memories; finally, the third section proposes different methodological alternatives to overcome the problems emerging from our analysis of literature.

The modern cast of disaster relief actors includes host nations, non-governmental organisations, private volunteer organisations, military organisations and others. Each group, civilian or military, has valuable skills and experiences critical to disaster relief work. The goal of this paper is to supplement the study of civil-military relief efforts with contemporary anecdotal experience. The paper examines the interaction between US military forces and other disaster relief actors during the 2005 Kashmir earthquake relief effort. The author uses direct observations made while working in Pakistan to contrast the relationships and activities from that effort with other accounts in prevailing scholarly disaster literature and military doctrine. Finally, this paper suggests that the Kashmir model of integration, coordination and transparency of intent creates a framework in which future humanitarian assistance operations could be successfully executed. Recommendations to improve civil-military interaction in future relief efforts will also be addressed.
Methodological issues in the study of violence against women
Ruiz‐Pérez, Isabel; Plazaola‐Castaño, Juncal; Vives‐Cases, Carmen
2007-01-01
The objective of this paper is to review the methodological issues that arise when studying violence against women as a public health problem, focusing on intimate partner violence (IPV), since this is the form of violence that has the greatest consequences at a social and political level. The paper focuses first on the problems of defining what is meant by IPV. Secondly, the paper describes the difficulties in assessing the magnitude of the problem. Obtaining reliable data on this type of violence is a complex task, because of the methodological issues derived from the very nature of the phenomenon, such as the private, intimate context in which this violence often takes place, which means the problem cannot be directly observed. Finally, the paper examines the limitations and bias in research on violence, including the lack of consensus with regard to measuring events that may or may not represent a risk factor for violence against women or the methodological problem related to the type of sampling used in both aetiological and prevalence studies.

This paper reports the relationship between the difficulty level and the discrimination power of true/false-type multiple-choice questions (MCQs) in a multidisciplinary paper for the para-clinical year of an undergraduate medical programme. MCQ items in papers taken from Year II Parts A, B and C examinations for Sessions 2001/02, and Part B examinations for 2002/03 and 2003/04, were analysed to obtain their difficulty indices and discrimination indices. Each paper consisted of 250 true/false items (50 questions of 5 items each) on topics drawn from different disciplines. The questions were first constructed and vetted by the individual departments before being submitted to a central committee, where the final selection of the MCQs was made, based purely on the academic judgement of the committee. There was a wide distribution of item difficulty indices in all the MCQ papers analysed. Furthermore, the relationship between the difficulty index (P) and discrimination index (D) of the MCQ items in a paper was not linear, but more dome-shaped. Maximal discrimination (D = 51% to 71%) occurred with moderately easy/difficult items (P = 40% to 74%). On average, about 38% of the MCQ items in each paper were "very easy" (P > or =75%), while about 9% were "very difficult" (P <25%). About two-thirds of these very easy/difficult items had "very poor" or even negative discrimination (D < or =20%). MCQ items that demonstrate good discriminating potential tend to be moderately difficult items, and the moderately-to-very difficult items are more likely to show negative discrimination. There is a need to evaluate the effectiveness of our MCQ items.
Why Veterinary Medical Educators Should Embrace Cumulative Final Exams.
Royal, Kenneth D
The topic of cumulative final examinations often elicits polarizing opinions from veterinary medical educators. While some faculty prefer cumulative finals, there are many who perceive these types of examinations as problematic. Specifically, faculty often cite cumulative examinations are more likely to cause students' greater stress, which may in turn result in negative student evaluations of teaching. Cumulative finals also restrict the number of items one may present to students on most recent material. While these cited disadvantages may have some merit, the advantages of cumulative examinations far exceed the disadvantages. The purpose of this article is to discuss the advantages of cumulative examinations with respect to learning evidence, grade/score validity, fairness issues, and implications for academic policy.
General Aviation in Nebraska: Nebraska SATS Project Background Paper No. 1

Smith, Russell; Wachal, Jocelyn
2000-01-01
The Nebraska SATS project is a state-level component of NASA's Small Aircraft Transportation System (SATS). During the next several years the project will examine several different factors affecting SATS implementation in Nebraska. These include economic and taxation issues, public policy issues, airport planning processes, information dissemination strategies, and systemic change factors. This background paper profiles the general aviation system in Nebraska. It is written to provide information about the "context" within which SATS will be pursued. The primary focus is thus on describing and providing background information about the current situation. A secondary focus is on drawing general conclusions about the ability of the current system to incorporate the types of changes implied by SATS. First, some brief information on the U.S. aviation system is provided. The next two sections profile the current general aviation aircraft and pilot base. Nebraska's system of general aviation airports is then described. Within this section of the paper, information is provided on the different types of general aviation airports in Nebraska, airport activity levels and current infrastructure. The fourth major section of the background paper looks at Nebraska's local airport authorities. These special purpose local governments oversee the majority of the general aviation airports in the state. Among the items examined are total expenditures, capital expenditures and planning activities. Next, the paper provides background information on the Nebraska Department of Aeronautics (NDA) and recent Federal funding for general aviation in Nebraska. The final section presents summary conclusions.

This paper presents a new review of our knowledge of the ancient forest beetle fauna from Holocene archaeological and palaeoecological sites in Great Britain and Ireland. It examines the colonisation, dispersal and decline of beetle species, highlighting the scale and nature of human activities in the shaping of the landscape of the British Isles. In particular, the paper discusses effects upon the insect fauna, and examines in detail the fossil record from the Humberhead Levels, eastern England. It discusses the local extirpation of up to 40 species in Britain and 15 species in Ireland. An evaluation of the timing of extirpations is made, suggesting that many species in Britain disappear from the fossil record between ca 3000 and 1000 cal BC (ca 5000-3000 cal BP), although some taxa may well have survived until considerably later. In Ireland, there are two distinct trends, with a group of species which seem to be absent after ca 2000 cal BC (ca 4000 cal BP) and a further group which survives until at least as late as the medieval period. The final clearance of the Irish landscape over the last few hundred years was so dramatic, however, that some species which are not especially unusual in a British context were decimated. Reasons behind the extirpation of taxa are examined in detail, and include a combination of forest clearance and human activities, isolation of populations, lack of temporal continuity of habitats, edaphic and competition factors affecting distribution of host trees (particularly pine), lack of forest fires and a decline in open forest systems. The role of climate change in extirpations is also evaluated. Consideration is given to the significance of these specialised ancient forest inhabitants in Ireland in the absence of an early Holocene land-bridge which suggests that colonisation was aided by other mechanisms, such as human activities and wood rafting. Finally, the paper discusses the Continental origins of the British and Irish fauna and its hosts and the role played by European glacial refugia.
The butterfly effect of the "butterfly effect".
Dooley, Kevin J
2009-07-01
The "Butterfly Effect" metaphor states with variance that the flap of a butterfly's wings in Brazil can cause a tornado in Texas. This metaphor has become part of the common vernacular of Western culture. In this paper I discuss the origins of the metaphor, examine its current usage within popular culture, and present an argument as to why it is popular. I propose that the metaphor is a type of semantic attractor, a narrative device with invariant meaning but audience-specific contextualization. Finally I address whether the Butterfly Effect metaphor is a good example of itself.

Distortions in market processes for pharmaceuticals raise the important policy problem of devising measures to improve industry performance. This paper first reviews the basic issues involved in formulating economic policy regarding the pharmaceutical industry. Methods for reducing structural market power and undesirable promotional expenditures are examined, and the impacts of four oft-suggested policy "reforms"--removal of trade names, removal of patents, relaxation of requirements for certification of new drug products, and increased enforcement of antitrust laws--are then analyzed. Finally, problems requiring additional research are identified.
Gene-environment interactions in mental disorders
Tsuang, Ming T; Bar, Jessica L; Stone, William S; Faraone, Stephen V
2004-01-01
Research clearly shows that both nature and nurture play important roles in the genesis of psychopathology. In this paper, we focus on 'gene-environment interaction' in mental disorders, using genetic control of sensitivity to the environment as our definition of that term. We begin with an examination of methodological issues involving gene-environment interactions, with examples concerning psychiatric and neurological conditions. Then we review the interactions in psychiatric disorders using twin, adoption and association designs. Finally, we consider gene-environment interactions in selected neurodevelopmental disorders (autism and schizophrenia). PMID:16633461
Microalgae for economic applications: advantages and perspectives for bioethanol
Simas-Rodrigues, Cíntia; Villela, Helena D. M.; Martins, Aline P.; ...
2015-04-04
Renewable energy has attracted significant interest in recent years as a result of sustainability, environmental impact, and socio-economic considerations. Given existing technological knowledge and based on projections relating to biofuels derived from microalgae, microalgal feedstock is considered to be one of the most important renewable energy sources potentially available for industrial production. Finally and therefore, this paper examines microalgal bioethanol technology, which converts biomass from microalgae to fuel, the chemical processes involved, and possible ways of increasing the bioethanol yield, such as abiotic factors and genetic manipulation of fermenting organisms.
Gender and Psychological Essentialism
Heyman, Gail D.; Giles, Jessica W.
2010-01-01
SUMMARY When individuals reason in an essentialist way about social categories, they assume that group differences reflect inherently different natures (Gelman, 2003; Rothbart & Taylor, 1992). This paper describes the psychological and social implications of essentialist beliefs, and examines the extent to which children exhibit psychological essentialism when reasoning about gender. The authors discuss reasons young children as well as older children show essentialist reasoning in some contexts, but not in others. Finally, the authors suggest directions for future research, and discuss a primary challenge to many working in this field: reduction of rigid gender beliefs. PMID:21528097
AIDS Treatment In Brazil: Impacts And Challenges
Nunn, Amy Stewart; Fonseca, Elize Massard da; Bastos, Francisco I.; Gruskin, Sofia
2009-01-01
Brazil has one of the developing world's largest, and arguably most successful, AIDS treatment programs. In this paper we review the treatment program, including controversial policies that Brazil has used to promote widespread local and global access to AIDS treatment. We also examine the lessons learned from this program and highlight the challenges Brazil faces, including the rising costs of AIDS treatment and changes in donors' funding priorities. Finally, we explore the relevance of Brazil's treatment program for other countries and its broad implications for global AIDS and health policy. PMID:19597210
Coping with the threat of terrorism: a review.
Maguen, Shira; Papa, Anthony; Litz, Brett T
2008-01-01
Terrorism creates a ripple of fear and uncertainty. Although most individuals are resilient and recover over time, a minority remains functionally and psychologically impaired. In this paper, we examine research on coping strategies employed in the aftermath of terrorist events, theories and empirical findings related to appraisal processes that influence individuals' primary attributions of risk, and normative processes that shape secondary appraisals, which predict specific coping behaviors. We also describe individual diatheses and factors promoting resilience that may influence coping and functioning in the face of terrorism. Finally, we offer suggestions for future research.

The Opportunities and Threats of Turning Airports into Hubs
NASA Technical Reports Server (NTRS)
Kraus, Andreas; Koch, Benjamin
2006-01-01
This paper examines the opportunities and threats which arise when turning origin/destination airports into hubs. The analysis focuses on market development trends, competitive structures, especially in the light of airline network strategies and the growing rivalry between airports, and finally the potential financial impacts for the airport, including both investment efforts and the financial results from hub operations. We argue that in most cases a decision against converting a traditional origin/destination airport into a major transfer point is preferable to the transformation into a hub.
The evolutionary psychology of violence.
Goetz, Aaron T
2010-02-01
This paper reviews theory and research on the evolutionary psychology of violence. First, I examine evidence suggesting that humans have experienced an evolutionary history of violence. Next, I discuss violence as a context-sensitive strategy that might have provided benefits to our ancestors under certain circumstances. I then focus on the two most common forms of violence that plague humans -violence over status contests and intimate partner violence- outlining psychological mechanisms involved in each. Finally, I suggest that greater progress will be made by shifting the study from contexts to mechanisms.

The paper presents results from the development of higher order closure models for the phenomological modeling of high-speed compressible flows. The work presented includes the introduction of an improved pressure-strain correlationi model applicable in both the low- and high-speed regime as well as modifications to the isotropic dissipation rate to account for dilatational effects. Finally, the question of stiffness commonly associated with the solution of two-equation and Reynolds stress transport equations in wall-bounded flows is examined and ways of relaxing these restrictions are discussed.

Abstract: Background: Medical errors are one of the greatest problems in any healthcare systems. The best way to prevent such problems is errors identification and their roots. Failure Mode and Effects Analysis (FMEA) technique is a prospective risk analysis method. This study is a review of risk analysis using FMEA technique in different hospital wards and departments. Methods: This paper has systematically investigated the available databases. After selecting inclusion and exclusion criteria, the related studies were found. This selection was made in two steps. First, the abstracts and titles were investigated by the researchers and, after omitting papers which did not meet the inclusion criteria, 22 papers were finally selected and the text was thoroughly examined. At the end, the results were obtained. Results: The examined papers had focused mostly on the process and had been conducted in the pediatric wards and radiology departments, and most participants were nursing staffs. Many of these papers attempted to express almost all the steps of model implementation; and after implementing the strategies and interventions, the Risk Priority Number (RPN) was calculated to determine the degree of the technique’s effect. However, these papers have paid less attention to the identification of risk effects. Conclusions: The study revealed that a small number of studies had failed to show the FMEA technique effects. In general, however, most of the studies recommended this technique and had considered it a useful and efficient method in reducing the number of risks and improving service quality. PMID:28039688

Secondary level mathematics education in Ireland has recently experienced a period of significant change with the introduction of new curricula and the addition of an incentive to study upper secondary mathematics at the most advanced level (Higher Level). This incentive, typically referred to as 'bonus points', appears to have aided a significant increase in the number of students studying upper secondary mathematics at Higher Level. However, thematic analysis of interviews with experienced upper secondary mathematics examiners and exploration of mathematics diagnostic test data outlined in this paper suggest that the difficulty of the Higher Level upper secondary mathematics final examination in Ireland has reduced since the introduction of the bonus points initiative. The sharp increase in students attempting this examination coupled with a policy of maintaining a consistent proportion of students achieving passing grades was identified as a key reason for this possible reduction in standards.
Examining the ethico-legal aspects of the right to refuse treatment in Turkey.
Sert, Gurkan; Guven, Tolga
2013-10-01
This paper examines the ethico-legal problems regarding the right to refuse treatment in Turkey's healthcare system. We discuss these problems in the light of a recent case that was directly reported to us. We first summarise the experience of a chronically dependent patient (as recounted by her daughter) and her family during their efforts to refuse treatment and receive palliative care only. This is followed by a summary of the legal framework governing the limits of the right to refuse treatment in Turkey. With the help of this background information on the legal framework, we re-examine the ethico-legal aspects of the case and explain the underlying reasons for the problems the family and the patient experienced. Finally, we conclude that Turkey's legal framework relating to the right to refuse treatment needs to be clarified and amended in accordance with international conventions and fundamental human rights.

The influence of biomass energy consumption on CO2 emissions: a wavelet coherence approach.

In terms of today, one may argue, throughout observations from energy literature papers, that (i) one of the main contributors of the global warming is carbon dioxide emissions, (ii) the fossil fuel energy usage greatly contributes to the carbon dioxide emissions, and (iii) the simulations from energy models attract the attention of policy makers to renewable energy as alternative energy source to mitigate the carbon dioxide emissions. Although there appears to be intensive renewable energy works in the related literature regarding renewables' efficiency/impact on environmental quality, a researcher might still need to follow further studies to review the significance of renewables in the environment since (i) the existing seminal papers employ time series models and/or panel data models or some other statistical observation to detect the role of renewables in the environment and (ii) existing papers consider mostly aggregated renewable energy source rather than examining the major component(s) of aggregated renewables. This paper attempted to examine clearly the impact of biomass on carbon dioxide emissions in detail through time series and frequency analyses. Hence, the paper follows wavelet coherence analyses. The data covers the US monthly observations ranging from 1984:1 to 2015 for the variables of total energy carbon dioxide emissions, biomass energy consumption, coal consumption, petroleum consumption, and natural gas consumption. The paper thus, throughout wavelet coherence and wavelet partial coherence analyses, observes frequency properties as well as time series properties of relevant variables to reveal the possible significant influence of biomass usage on the emissions in the USA in both the short-term and the long-term cycles. The paper also reveals, finally, that the biomass consumption mitigates CO2 emissions in the long run cycles after the year 2005 in the USA.
Bipartite flocking for multi-agent systems

Fan, Ming-Can; Zhang, Hai-Tao; Wang, Miaomiao
2014-09-01
This paper addresses the bipartite flock control problem where a multi-agent system splits into two clusters upon internal or external excitations. Using structurally balanced signed graph theory, LaSalle's invariance principle and Barbalat's Lemma, we prove that the proposed algorithm guarantees a bipartite flocking behavior. In each of the two disjoint clusters, all individuals move with the same direction. Meanwhile, every pair of agents in different clusters moves with opposite directions. Moreover, all agents in the two separated clusters approach a common velocity magnitude, and collision avoidance among all agents is ensured as well. Finally, the proposed bipartite flock control method is examined by numerical simulations. The bipartite flocking motion addressed by this paper has its references in both natural collective motions and human group behaviors such as predator-prey and panic escaping scenarios.

The paper examines systems integration and its main levels at higher levels of control. At present, the systems integration is one of the main aspects participating in the consolidation processes and financial flows of a company. Systems Integration is a complicated emotionconsuming process and it is often a problem to choose the right approach and level of integration. The research focused on four levels of integration, while each of them is characterized by specific conditions. At each level, there is a summary of recommendations and practical experience. The paper also discusses systems integration between the information and MES levels. The main part includes user-level integration where we describe an example of such integration. Finally, we list recommendations and also possible predictions of the systems integration as one of the important factors in the future.

One aspect of the call for democracy in the recent Arab region uprisings is the issue of women's rights and gender equality. Three cultural and ideological forces have continued to shape the gender discourse in Arab Muslim-majority societies. They are: "Islamic" teaching and local traditions concerning women's roles in a given society; Western, European colonial perception of women's rights; and finally national gender-related policy reforms. This paper examines the past and present status of women and gender-educational inequality in the Arab world with particular reference to Egypt and Tunisia, prior to and post colonialism. Special attention is given to colonial legacy and its influence on gender and education; to current gender practices in the social sphere with a focus on women's modesty ( hijab); to international policies and national responses with regard to women's rights and finally to female participation in pre-university and higher education. These issues incorporate a discussion of cultural and religious constraints. The paper demonstrates similarities and differences between Egypt's and Tunisia's reform policies towards gender parity. It highlights the confrontation of conservative versus liberal ideologies that occurred in each country with the implementation of its gender-related reform policy.
Defensive Practice as ‘Fear-Based’ Practice: Social Work's Open Secret?
Whittaker, Andrew; Havard, Tirion
2016-01-01
Defensive practice has received attention through the Munro review of child protection, which has identified that current organisational cultures increase the likelihood of defensive practice. Whilst the wider socio-political climate that gives rise to defensive practice has been explored within the literature, little attention has been paid to the everyday realities of defensive practice. This paper reports the findings of a study into final year social work students' attitudes towards defensive practice within social work. Three focus groups were completed with a total of ninety final-year students that collected qualitative and quantitative data using interactive software. This paper examines how participants perceived defensive practice, both in general and when faced with real-life vignettes. Participants distinguished between pro-active behaviour (sins of commission) and passive behaviour (sins of omission), generally regarding the latter as less serious because it was less tangible and easier to attribute to more positive motives. Whilst the literature identifies defensive practice as deliberate behaviour, the focus group discussions suggest that it is a subtler and less conscious process. Whilst there was there was a general consensus about the nature of defensive practice, there was considerable disagreement about specific vignettes and several competing explanations are explored.

This paper examines the international exchange in surgery in the decades before World War I, a period of growing globalization in communication and transport. Focusing on Europe and North America, it looks first at the various means of exchange, especially surgical travel and the culture emerging around it and follows specific directions of exchange, from France and Britain, first to the German-speaking countries and finally to North America. Subsequently, the account turns to international organizations as an important means of exchange in this time period. The International Society of Surgery, in particular, provided a forum for a vivid internationalist discourse, which, however, stood in tension with simultaneous nationalist tendencies leading up to World War I. The paper finally discusses how the international exchange and communication at the time can be seen as an instance of modern surgeons claiming-and simultaneously trying to create-the global universality of surgical knowledge and practices, making sure that surgery is the same the world over. © The Author 2016.

The New Zealand Geothermal Workshop took place on 29th-31st October 1979 at the University of Auckland. Over 100 participants were present (a list is included in this volume) with 6 overseas visitors, bring the number of countries represented (including the Institute's Fellows) to 14. Forty papers were presented over the three days of the meeting, together with 23 poster papers presented by the students of the Institute. This second Proceedings volume has been prepared as a supplement to the volume of conference papers distributed at the meeting, and was produced subsequent to the Workshop. The fist section of this volumemore » includes additional papers presented at the meeting but not then available in printed form. The second part is a summary of the year's activities of the Geothermal Institute also presented in part at the meeting. These activities included some significant research contributions and original field investigations. Each fellow at the Institute was required as part of the course, to conduct an investigation and prepare a report which was presented at the Geothermal Workshop in a poster session. Abstracts of these project reports are included in this volume and five of the projects are reproduced in greater detail. Also included are outlines of the two original class projects conducted by the students and staff of the Institute, one a pre-feasibility study of the Ngawha Geothermal Field and the other an investigation of the Miranda Springs system. Finally, the lecture curriculum of the year's diploma course is presented in outline, together with the final examination papers. The two volumes of this document therefore include, as much as is possible within the restricted space, an overview of the Geothermal Institute's contribution to the development of geothermal energy together with a technical tribute to the many people involved in this very successful first year.« less

As seen through the previous reviews, each carbonaceous source of energy is associated with genotoxic and carcinogenic health risks; however, energy use is central to human society and provides many health benefits. These reviews examined the genotoxicity of carbonaceous sources of energy, focusing on the impacts due to the combustion of fuels and biomass. In previous reviews, information and data were used to examine occupational, industrial, household, and general environmental pollution as well as laboratory research. In this final summation, the effort is not only to summarize the previous reviews but to provide additional information to support any final conclusions. Included in the final observations are: (1) emissions from combusted carbonaceous fuels are very likely to include genotoxicants and/or carcinogens, and, as such, they can considerably increase the risk of adverse health effects in exposed humans, (2) environmental transformation is likely to increase genotoxicity of emissions, and (3) the world's poor households have an increased health risk because they have limited access to clean fuels and electricity. Because carbonaceous fuel emissions are highly complex, risk assessments are difficult; however, decision makers have many toxicological approaches for evaluating emissions. Although energy efficiency brings many benefits, it also involves health risks, as do renewable energy systems, if not managed carefully. The reviews do not examine climate change or non-carbonaceous fuels (e.g., nuclear fuels). Because these are not papers about the risk assessment or regulation of pollutants from carbon-based fuels, the discussions of regulations were to place research, concerns, and actions into a historical reference for the reader.

Visual function and fitness to drive.
Kotecha, Aachal; Spratt, Alexander; Viswanathan, Ananth
2008-01-01
Driving is recognized to be a visually intensive task and accordingly there is a legal minimum standard of vision required for all motorists. The purpose of this paper is to review the current United Kingdom (UK) visual requirements for driving and discuss the evidence base behind these legal rules. The role of newer, alternative tests of visual function that may be better indicators of driving safety will also be considered. Finally, the implications of ageing on driving ability are discussed. A search of Medline and PubMed databases was performed using the following keywords: driving, vision, visual function, fitness to drive and ageing. In addition, papers from the Department of Transport website and UK Royal College of Ophthalmologists guidelines were studied. Current UK visual standards for driving are based upon historical concepts, but recent advances in technology have brought about more sophisticated methods for assessing the status of the binocular visual field and examining visual attention. These tests appear to be better predictors of driving performance. Further work is required to establish whether these newer tests should be incorporated in the current UK visual standards when examining an individual's fitness to drive.
Space: the final frontier in the learning of science?

Milne, Catherine
2014-03-01
In Space, relations, and the learning of science, Wolff-Michael Roth and Pei-Ling Hsu use ethnomethodology to explore high school interns learning shopwork and shoptalk in a research lab that is located in a world class facility for water quality analysis. Using interaction analysis they identify how spaces, like a research laboratory, can be structured as smart spaces to create a workflow (learning flow) so that shoptalk and shopwork can projectively organize the actions of interns even in new and unfamiliar settings. Using these findings they explore implications for the design of curriculum and learning spaces more broadly. The Forum papers of Erica Blatt and Cassie Quigley complement this analysis. Blatt expands the discussion on space as an active component of learning with an examination of teaching settings, beyond laboratory spaces, as active participants of education. Quigley examines smart spaces as authentic learning spaces while acknowledging how internship experiences all empirical elements of authentic learning including open-ended inquiry and empowerment. In this paper I synthesize these ideas and propose that a narrative structure might better support workflow, student agency and democratic decision making.
Seasonal infectious disease epidemiology
Grassly, Nicholas C; Fraser, Christophe
2006-01-01
Seasonal change in the incidence of infectious diseases is a common phenomenon in both temperate and tropical climates. However, the mechanisms responsible for seasonal disease incidence, and the epidemiological consequences of seasonality, are poorly understood with rare exception. Standard epidemiological theory and concepts such as the basic reproductive number R0 no longer apply, and the implications for interventions that themselves may be periodic, such as pulse vaccination, have not been formally examined. This paper examines the causes and consequences of seasonality, and in so doing derives several new results concerning vaccination strategy and the interpretation of disease outbreak data. It begins with a brief review of published scientific studies in support of different causes of seasonality in infectious diseases of humans, identifying four principal mechanisms and their association with different routes of transmission. It then describes the consequences of seasonality for R0, disease outbreaks, endemic dynamics and persistence. Finally, a mathematical analysis of routine and pulse vaccination programmes for seasonal infections is presented. The synthesis of seasonal infectious disease epidemiology attempted by this paper highlights the need for further empirical and theoretical work. PMID:16959647
The global financial crisis and the Great Recession of 2007-2009.
Dore, Mohammed H I; Singh, Rajiv G
2010-07-01
This paper is a re-examination of the global financial crisis that began in and was accompanied by the most severe recession since the Great Depression. It builds on our earlier paper (Dore and Singh, 2009) and expands its scope. It is divided into parts. The first part deals with the ideological backdrop in which this crisis occurred, namely the belief in the rationality and stability of all markets including the capital markets, called the 'efficient market hypothesis.' The second part is a survey of the role of income distribution and its relations to aggregate spending and the growing role played by credit in the circular flow of income. The third part examines some features of the business cycle expansion phase of to . The fourth part is a brief report on a nonlinear Vector Error Correction model spanning the period to and how this expansion came to an end. The fifth part is a brief comparison of the Great Recession with the Great Depression. Finally in the sixth part, the international impact of the Great Recession is considered briefly, followed by some conclusions.

This paper examines the relationship between body composition and wages in the United States. We develop measures of body composition--body fat (BF) and fat-free mass (FFM)--using data on bioelectrical impedance analysis (BIA) that are available in the National Health and Nutrition Examination Survey III and estimate wage models for respondents in the National Longitudinal Survey of Youth 1979. Previous research uses body size or BMI as measures of obesity despite a growing concern that they do not distinguish between body fat and fat-free body mass or adequately control for non-homogeneity inside the human body. Therefore, measures presented in this paper represent a useful alternative to BMI-based proxies of obesity. Our results indicate that BF is associated with decreased wages for both males and females among whites and blacks. We also present evidence suggesting that FFM is associated with increased wages. We show that these results are not the artifacts of unobserved heterogeneity. Finally, our findings are robust to numerous specification checks and to a large number of alternative BIA prediction equations from which the body composition measures are derived. 2010 Elsevier B.V.

2010-06-11
This paper examines the attractiveness of materials mixtures containing special nuclear materials (SNM) associated with the various processing steps required for a closed fuel cycle. This paper combines the results from earlier studies that examined the attractiveness of SNM associated with the processing of spent light water reactor (LWR) fuel by various reprocessing schemes and the recycle of plutonium as a mixed oxide (MOX) fuel in LWR with new results for the final, repeated burning of SNM in fast-spectrum reactors: fast reactors and accelerator driven systems (ADS). The results of this paper suggest that all reprocessing products evaluated so farmore » need to be rigorously safeguarded and provided moderate to high levels of physical protection. These studies were performed at the request of the United States Department of Energy (DOE), and are based on the calculation of "attractiveness levels" that has been couched in terms chosen for consistency with those normally used for nuclear materials in DOE nuclear facilities. The methodology and key findings will be presented. Additionally, how these attractiveness levels relate to proliferation resistance (e.g. by increasing impediments to the diversion, theft, or undeclared production of SNM for the purpose of acquiring a nuclear weapon), and how they could be used to help inform policy makers, will be discussed.« less
Virtual water flows and trade liberalization.
Ramirez-Vallejo, J; Rogers, P
2004-01-01
The linkages between agricultural trade and water resources need to be identified and analyzed to better understand the potential impacts that a full liberalization, or lack thereof, will have on water resources. This paper examines trade of virtual water embodied in agricultural products for most countries of the world. The main purpose of the paper, however, is to examine the impact of trade liberalization on virtual-water trade in the future. Based on a simulation of global agricultural trade, a scenario of full liberalization of agriculture was used to assess the net effect of virtual water flows from the relocation of meat and cereals' trade. The paper also identifies the main reasons behind the changes in the magnitude and direction of the net virtual water trade over time, and shows that virtual water trade flows are independent of water resource endowments, contrary to what the Heckscher-Ohlin Theorem states. Finally, based on a formal model, some input demand functions at the country level are estimated. The estimates of the income and agricultural support elasticities of demand for import of virtual water have the expected sign, and are statistically significant. Variables found to have some explanatory power of the variance of virtual water imports are average income; population; agriculture as value added; irrigated area, and exports of goods and services.
On the Maximum Speed of Matter
NASA Astrophysics Data System (ADS)
Raftopoulos, Dionysios G.
2013-09-01
In this paper we examine the analytical production of the Lorentz Transformation regarding its fundamental conclusion i.e. that the speed of Light in vacuum is the uppermost limit for the speed of matter, hence superluminal speeds are unattainable. This examination covers the four most prominent relevant sources of bibliography: Albert Einstein's historic paper (1905) titled: "On the Electrodynamics of moving Bodies" on which his Special Relativity Theory is founded. His famous textbook titled: "Relativity, The Special and General Theory", A. P. French's textbook titled "Special Relativity", Wolfgang Rindler's textbook titled: "Essential Relativity". Special emphasis is placed on the critical analysis of Einstein's gedanken experiment as it is presented in his original paper, where he considers a moving, straight, rigid rod at the ends of which there are two clocks, whose synchronization is checked according to his own definition as given in part 1 of his paper. By applying the second fundamental hypothesis (principle) of SRT, we arrive at the conclusion that this noetic experiment can be concluded only if the rod's speed V with regards the stationary system and measured from it, is less than the speed of light C also with regards the stationary system and measured from it. In the opposite case, said noetic experiment would be meaningless as it could never be concluded for the Observer of the stationary system, at least in the Euclidean Space. Finally, we show that in all four cases under examination the relationship v < c is not a conclusion of the Lorentz Transformation, but rather a hidden pre-condition of its analytical production, in other words, the LT can only be valid for v < c Consequently, there doesn't exist a definite and rigid law of Physics forbidding matter to travel with superluminal velocity in vacuum.
[Introduction and some problems of the rapid time series laboratory reporting system].
Kanao, M; Yamashita, K; Kuwajima, M
1999-09-01
We introduced an on-line system of biochemical, hematological, serological, urinary, bacteriological, and emergency examinations and associated office work using a client server system NEC PC-LACS based on a system consisting of concentration of outpatient blood collection, concentration of outpatient reception, and outpatient examination by reservation. Using this on-line system, results of 71 items in chemical serological, hematological, and urinary examinations are rapidly reported within 1 hour. Since the ordering system at our hospital has not been completed yet, we constructed a rapid time series reporting system in which time series data obtained on 5 serial occasions are printed on 2 sheets of A4 paper at the time of the final report. In each consultation room of the medical outpatient clinic, at the neuromedical outpatient clinic, and at the kidney center where examinations are frequently performed, terminal equipment and a printer for inquiry were established for real-time output of time series reports. Results are reported by FAX to the other outpatient clinics and wards, and subsequently, time series reports are output at the clinical laboratory department. This system allowed rapid examination, especially preconsultation examination. This system was also useful for reducing office work and effectively utilize examination data.

Advanced safety vehicle(ASV)assists drivers’ manipulation to avoid trafic accidents. A variety of researches on automatic driving systems are necessary as an element of ASV. Among them, we focus on visual feedback approach in which the automatic driving system is realized by recognizing road trajectory using image information. The purpose of this paper is to examine the validity of this approach by experiments using a radio-controlled car. First, a practical image processing algorithm to recognize white lines on the road is proposed. Second, a model of the radio-controlled car is built by system identication experiments. Third, an automatic steering control system is designed based on H∞ control theory. Finally, the effectiveness of the designed control system is examined via traveling experiments.

Mixed methods research has made significant in-roads in the effort to examine complex health related phenomenon. However, little has been published on the funding of mixed methods research projects. This paper addresses that gap by presenting an example of an NIMH funded project using a mixed methods QUAL-QUAN triangulation design entitled “The Mixed-Method Analysis of Japanese Depression.” We present the Cultural Determinants of Health Seeking model that framed the study, the specific aims, the quantitative and qualitative data sources informing the study, and overview of the mixing of the two studies. Finally, we examine reviewer's comments and our insights related to writing mixed method proposal successful for achieving RO1 level funding. PMID:25419196

In this paper, effects of pin thread and thread interruptions (flats) on weld quality and process response parameters during friction stir welding (FSW) of 6061 aluminium alloy were quantified. Otherwise, identical smooth and threaded pins with zero to four flats were adopted for FSW. Weldability and process response variables were examined. Results showed that threads with flats significantly improved weld quality and reduced in-plane forces. A three-flat threaded pin led to production of defect-free welds under all examined welding conditions. Spectral analyses of in-plane forces and weld cross-sectional analysis were performed to establish correlation among pin flats, force dynamics andmore » defect formation. Finally, the lowest in-plane force spectra amplitudes were consistently observed for defect-free welds.« less

Inflation with a smooth constant-roll to constant-roll era transition

Odintsov, S. D.; Oikonomou, V. K.
2017-07-01
In this paper, we study canonical scalar field models, with a varying second slow-roll parameter, that allow transitions between constant-roll eras. In the models with two constant-roll eras, it is possible to avoid fine-tunings in the initial conditions of the scalar field. We mainly focus on the stability of the resulting solutions, and we also investigate if these solutions are attractors of the cosmological system. We shall calculate the resulting scalar potential and, by using a numerical approach, we examine the stability and attractor properties of the solutions. As we show, the first constant-roll era is dynamically unstable towards linear perturbations, and the cosmological system is driven by the attractor solution to the final constant-roll era. As we demonstrate, it is possible to have a nearly scale-invariant power spectrum of primordial curvature perturbations in some cases; however, this is strongly model dependent and depends on the rate of the final constant-roll era. Finally, we present, in brief, the essential features of a model that allows oscillations between constant-roll eras.

In a vehicle constrained by mass and power, it is necessary to ensure that during the process of reducing hardware mass and power that the health and well being of the crew is not compromised in the design process. To that end, it is necessary to ensure that in the final phase of flight - recovery, that the crew core body temperature remains below the crew cognitive deficit set by the Constellation program. This paper will describe the models used to calculate the thermal environment of the spacecraft after splashdown as well as the human thermal model used to calculate core body temperature. Then the results of these models will be examined to understand the key drivers for core body temperature. Finally, the analysis results will be used to show that additional cooling capability must be added to the vehicle to ensure crew member health post landing.
School-site decision making in multicultural education: An Australian perspective

Kennedy, Kerry J.
1985-12-01
This paper examines a number of issues related to multicultural education and curriculum change. It focuses on school-level projects that were developed in Western Australian schools from 1979-1981. The results of the research raised the following points: teachers viewed multicultural education as a psycho-social rather than a socio-political phenomenon; the aims of multicultural education were seen to be best achieved by the collection of specific resource material; on-site implementation of the projects often led to changes being made to the original intentions of the project designers; qualitative research techniques proved more sensitive in portraying and consequently understanding the complexities associated with project implementation, and, finally, it seemed clear that more emphasis should be placed on understanding the role of the teacher as a policy mediator. It is at the school level that the final decisions are made about national policy intentions.

An energy independent scaling of the near-side ridge yield at a given multiplicity has been observed by the ATLAS and the CMS collaborations in p +p collisions at √{s }=7 and 13 TeV. Such a striking feature of the data can be successfully explained by approaches based on initial state momentum space correlation generated due to gluon saturation. In this paper, we try to examine if such a scaling is also an inherent feature of the approaches that employ strong final state interaction in p +p collisions. We find that hydrodynamical modeling of p +p collisions using EPOS 3 shows a violation of such scaling. The current study can, therefore, provide important new insights on the origin of long-range azimuthal correlations in high multiplicity p +p collisions at the LHC energies.

An EMU water processing kit (Airlock Coolant Loop Recovery -- A/L CLR) was developed as a corrective action to Extravehicular Mobility Unit (EMU) coolant flow disruptions experienced on the International Space Station (ISS) in May of 2004 and thereafter. A conservative duty cycle and set of use parameters for A/L CLR use and component life were initially developed and implemented based on prior analysis results and analytical modeling. Several initiatives were undertaken to optimize the duty cycle and use parameters of the hardware. Examination of post-flight samples and EMU Coolant Loop hardware provided invaluable information on the performance of the A/L CLR and has allowed for an optimization of the process. The intent of this paper is to detail the evolution of the A/L CLR hardware, efforts to optimize the duty cycle and use parameters, and the final recommendations for implementation in the post-Shuttle retirement era.
Towards adaptation in e-learning 2.0

This paper presents several essential steps from an overall study on shaping new ways of learning and teaching, by using the synergetic merger of three different fields: Web 2.0, e-learning and adaptation (in particular, personalisation to the learner). These novel teaching and learning ways-the latter focus of this paper-are reflected in and finally adding to various versions of the My Online Teacher 2.0 adaptive system. In particular, this paper focuses on a study of how to more effectively use and combine the recommendation of peers and content adaptation to enhance the learning outcome in e-learning systems based on Web 2.0. In order to better isolate and examine the effects of peer recommendation and adaptive content presentation, we designed experiments inspecting collaboration between individuals based on recommendation of peers who have greater knowledge, and compare this to adaptive content recommendation, as well as to "simple" learning in a system with a minimum of Web 2.0 support. Overall, the results of adding peer recommendation and adaptive content presentation were encouraging, and are further discussed in detail in this paper.

Usmen, M. A.; Vilnitis, M.
2015-11-01
This paper examines the success indicators of construction projects, safety, quality and productivity, in terms of their implications and impacts during and after construction. First safety is considered during construction with a focus on hazard identification and the prevention of occupational accidents and injuries on worksites. The legislation mandating safety programs, training and compliance with safety standards is presented and discussed. Consideration of safety at the design stage is emphasized. Building safety and the roles of building codes in prevention of structural failures are also covered in the paper together with factors affecting building failures and methods for their prevention. Quality is introduced in the paper from the perspective of modern total quality management. Concepts of quality management, quality control, quality assurance and Six Sigma and how they relate to building quality and structural integrity are discussed with examples. Finally, productivity concepts are presented with emphasis on effective project management to minimize loss of productivity, complimented by lean construction and lean Six Sigma principles. The paper concludes by synthesizing the relationships between safety, quality and productivity.

The United States's aeronautical research program has been rich in the use of research aircraft to explore new flight regimes, develop individual aeronautical concepts, and investigate new vehicle classes and configurations. This paper reviews the NASA supercritical wing, digital fly-by-wire, HiMAT, and AD-1 oblique-wing flight research programs, and draws from these examples general conclusions regarding the role and impact of research aircraft in technology development. The impact of a flight program on spinoff technology is also addressed. The secondary, serendipitous results are often highly significant. Finally, future research aircraft programs are examined for technology trends and expected results.
Lesbians still face job discrimination.
Ryniker, Margaret R
2008-01-01
This article examines continued discrimination against lesbians in the workplace. A number of cases from various jurisdictions in the United States are highlighted. The paper studies two common forms of discrimination: denial of employment benefits to same sex partners, and sexual harassment. On the first front, the case law suggests that health insurance coverage for one's partner is becoming the norm. On the question of sexual harassment in the workplace, the case law did not provide protection for lesbians. Finally, U.S. employment policies related to sexual orientation are contrasted with those in Israel, which provides much greater protection from discrimination.
Must doctors save their patients?

1983-12-01
Do doctors and other medical staff have an obligation to treat those who need their help? This paper assumes no legal or contractual obligations but attempts to discover whether there is any general moral obligation to treat those in need. In particular the questions of whether or not the obligation that falls on medical staff is different from that of others and of whether doctors are more blameworthy than others if they fail to treat patients are examined. Finally we look at the question of the burden of this obligation and at the responsibility of society to mitigate its hardships.

Hall number across a van Hove singularity
Maharaj, Akash V.; Esterlis, Ilya; Zhang, Yi; ...
2017-07-24
In this paper, in the context of the relaxation time approximation to Boltzmann transport theory, we examine the behavior of the Hall number n H of a metal in the neighborhood of a Lifshitz transition from a closed Fermi surface to open sheets. We find a universal nonanalytic dependence of n H on the electron density in the high-field limit, but a nonsingular dependence at low fields. Finally, the existence of an assumed nematic transition produces a doping dependent n H similar to that observed in recent experiments in the high-temperature superconductor YBa 2Cu 3O 7-x.

A seemingly insatiable demand for energy characterizes Egypt as it approaches the end of the twentieth century. With the limited energy resources in the country, R and D to utilize renewable sources of energy is a must. This paper examines first the energy situation in Egypt and explores the potential of using solar energy in hydrogen production from water. Different schemes of dissociating water are reviewed next. Finally, research findings are reported for some experimental runs carried out for the electrolysis of water by solar energy, utilizing an eight-water photovoltaic cell (Telephonken type) to generate the DC current.
On the trajectories of null and timelike geodesics in different wormhole geometries

Mishra, Anuj; Chakraborty, Subenoy
2018-05-01
The paper deals with an extensive study of null and timelike geodesics in the background of wormhole geometries. Starting with a spherically symmetric spacetime, null geodesics are analyzed for the Morris-Thorne wormhole (WH) and photon spheres are examined in WH geometries. Both bounded and unbounded orbits are discussed for timelike geodesics. A similar analysis has been done for trajectories in a dynamic spherically symmetric WH and for a rotating WH. Finally, the invariant angle method of Rindler and Ishak has been used to calculate the angle between radial and tangential vectors at any point on the photon's trajectory.

Ghosh, D.; Ray, S.; Mandal, A.; Roy, H.
2015-04-01
This paper highlights a case study of typical premature failure of a radiant platen superheater tube of 210 MW thermal power plant boiler. Visual examination, dimensional measurement and chemical analysis, are conducted as part of the investigations. Apart from these, metallographic analysis and fractography are also conducted to ascertain the probable cause of failure. Finally it has been concluded that the premature failure of the super heater tube can be attributed to localized creep at high temperature. The corrective actions has also been suggested to avoid this type of failure in near future.
Cheating and sports: history, diagnosis and treatment.

This paper focuses on "cheating" in modern day athletics from youth through professional sports. We briefly summarize a history of cheating in the sports world. We examine the current role cheating plays in sports as well as its causes including, psychodynamic issues, the development of personality disorders and how personality traits become pathological resulting in deception, dishonesty, and underhandedness. We describe management and treatment including psychotherapeutic intervention as well as medication. Finally we discuss a systems approach involving outreach to coaches, families, and related sports organizations (like FIFA, WADA, etc) or the professional leagues which have institutional control and partial influence on the athlete.

In this paper we present a comprehensive and detailed study of Interatomic Coulombic Decay (ICD) occurring after irradiating argon dimers with XUV-synchrotron radiation. A manifold of different decay channels is observed and the corresponding initial and final states are assigned. Additionally, the effect of nuclear dynamics on the ICD electron spectrum is examined for one specific decay channel. The internuclear distance-dependent width Γ(R) of the decay is obtained from the measured kinetic energy release distribution of the ions employing a classical nuclear dynamics model.

This paper considers how best to approach dilemmas posed to global health and biosecurity policy by increasing advances in practical applications of nanotechnology. The type of nano-technology policy dilemmas discussed include: (1) expenditure of public funds, (2) public-funded research priorities, (3) public confidence in government and science and, finally, (4) public safety. The article examines the value in this context of a legal obligation that the development of relevant public health law be calibrated against less corporate-influenced norms issuing from bioethics and international human rights.

This paper reviews the psychophysical basis for auditory models and discusses their application to automatic speech recognition. First an overview of the human auditory system is presented, followed by a review of current knowledge gleaned from neurological and psychoacoustic experimentation. Next, a general framework describes established peripheral auditory models which are based on well-understood properties of the peripheral auditory system. This is followed by a discussion of current enhancements to that models to include nonlinearities and synchrony information as well as other higher auditory functions. Finally, the initial performance of auditory models in the task of speech recognition is examined and additional applications are mentioned.
Review of HIV Testing Efforts in Historically Black Churches
Pichon, Latrice Crystal; Powell, Terrinieka Williams
2015-01-01
This paper aims to critically assess the state of HIV testing in African American churches. A comprehensive review of peer-reviewed publications on HIV testing in church-based settings was conducted by two independent coders. Twenty-six papers published between 1991 and 2015, representing 24 unique projects, were identified addressing at least one dimension of HIV testing. Thirteen faith-based projects have implemented HIV testing events or had clergy promote the importance of testing and knowing one’s HIV status, but empirical data and rigorous study designs were limited. Only eight papers reported onsite HIV testing in churches. Less than 5% of the studies reported the percentage of congregants who returned for their test results. Finally, no study has examined at baseline or post-intervention behavioral intentions to be screened for HIV. Future research is needed to evaluate the effectiveness of HIV testing in churches and to explore the possibilities of the role of the church and leadership structure in the promotion of HIV treatment and care.

GEOTHERMAL / SOLAR HYBRID DESIGNS: USE OF GEOTHERMAL ENERGY FOR CSP FEEDWATER HEATING
DOE Office of Scientific and Technical Information (OSTI.GOV)
Craig Turchi; Guangdong Zhu; Michael Wagner
2014-10-01
This paper examines a hybrid geothermal / solar thermal plant design that uses geothermal energy to provide feedwater heating in a conventional steam-Rankine power cycle deployed by a concentrating solar power (CSP) plant. The geothermal energy represents slightly over 10% of the total thermal input to the hybrid plant. The geothermal energy allows power output from the hybrid plant to increase by about 8% relative to a stand-alone CSP plant with the same solar-thermal input. Geothermal energy is converted to electricity at an efficiency of 1.7 to 2.5 times greater than would occur in a stand-alone, binary-cycle geothermal plant usingmore » the same geothermal resource. While the design exhibits a clear advantage during hybrid plant operation, the annual advantage of the hybrid versus two stand-alone power plants depends on the total annual operating hours of the hybrid plant. The annual results in this draft paper are preliminary, and further results are expected prior to submission of a final paper.« less
I saw the sign: the new federal menu-labeling law and lessons from local experience.
Banker, Michelle I
2010-01-01
Following the lead of several state and local governments, Congress recently imposed menu-labeling requirements on chain restaurants as part of the federal health care reform bill signed into law in March 2010. Section 4205 of the Patient Protection and Affordable Care Act requires restaurant chains with 20 or more locations nationwide to display calorie information for standard menu items on menus, menu boards, and drive-thru displays. This paper examines the new federal law in light of existing state and local regulations and considers the arguments for and against mandatory calorie labeling at restaurants as a federal tool for preventing obesity. Specifically, this paper examines the provisions of the new federal law, highlights how it differs from the municipal and state menu-labeling laws already in effect, reviews early studies of the effectiveness of these state and local laws, and considers the propriety of requiring restaurants to disclose calorie information on menus by discussing arguments for and against menu labeling generally and calorie labeling in particular. This paper finds that based on initial studies of state and local menu-labeling regulations, the efficacy of compulsory menu labeling as a tool to combat obesity remains uncertain. Finally, this paper raises practical considerations associated with the new federal law, including implementation issues, potential collateral effects of the law, a survey of legal challenges that may arise, and a discussion of the Food and Drug Administration's competence to enforce a menu-labeling requirement against restaurants.
Tablet computers in assessing performance in a high stakes exam: opinion matters.

Background Tablet computers have emerged as a tool to capture, process and store data in examinations, yet evidence relating to their acceptability and usefulness in assessment is limited. Methods We performed an observational study to explore opinions and attitudes relating to tablet computer use in recording performance in a final year objective structured clinical examination at a single UK medical school. Examiners completed a short questionnaire encompassing background, forced-choice and open questions. Forced choice questions were analysed using descriptive statistics and open questions by framework analysis. Results Ninety-two (97% response rate) examiners completed the questionnaire of whom 85% had previous use of tablet computers. Ninety per cent felt checklist mark allocation was 'very/quite easy', while approximately half considered recording 'free-type' comments was 'easy/very easy'. Greater overall efficiency of marking and resource savings were considered the main advantages of tablet computers, while concerns relating to technological failure and ability to record free type comments were raised. Discussion In a context where examiners were familiar with tablet computers, they were preferred to paper checklists, although concerns were raised. This study adds to the limited literature underpinning the use of electronic devices as acceptable tools in objective structured clinical examinations.
Poverty and Serious Mental Illness: Toward Action on a Seemingly Intractable Problem.
Sylvestre, John; Notten, Geranda; Kerman, Nick; Polillo, Alexia; Czechowki, Konrad
2018-03-01
This paper examines the issue of poverty among people with serious mental illness (SMI), positioning it as a key issue to be confronted by community mental health systems and practitioners. The paper reviews three perspectives on poverty, considering how each sheds light on poverty among people with SMI, and their implications for action: (a) monetary resources, (b) basic needs, and (c) capabilities. The paper argues that community mental health programs and systems are currently unable to address poverty as they are overly focused on individual-level interventions that, on their own, cannot raise people out of poverty. The paper calls for a social justice value, informed by the concept of citizenship, as a necessary complement to the recovery concept that has informed community mental health practice for almost 25 years. Finally, the paper argues that community psychologists, with their concepts, methods, and values, are well positioned to contribute to this important issue. However, it also contends that addressing poverty requires collaboration from community psychologists with researchers and practitioners from other fields and domains of expertise to begin to make progress. © Society for Community Research and Action 2017.
The biology of homosexuality: sexual orientation or sexual preference?
De Cecco, J P; Parker, D A
1995-01-01
This paper begins with a summary of the biological research on homosexuality that occurred in the late 1980s and early 1990s. It then summarizes the treatment of this research chiefly by the print media. It then adumbrates the presuppositions about sexuality and gender upon which the reports were based. It is argued that the presuppositions, which are asserted without being examined, date back to the nineteenth century. They ignore the historical, sociocultural, and humanistic research of the last two decades that collectively comprise the field of gay, lesbian, and bisexual studies. The discussion of the issue of choice follows and it recognizes the various constraints on choice without eliminating it as an element of sexual expression. Finally, the paper sets forth a general conception of homosexuality that includes its psychological and socio-cultural dimensions along with the biological.
Intersubjectivity in schizophrenia: life story analysis of three cases
Irarrázaval, Leonor; Sharim, Dariela
2014-01-01
The processes involved in schizophrenia are approached from a viewpoint of understanding, revealing those social elements susceptible to integration for psychotherapeutic purposes, as a complement to the predominant medical-psychiatric focus. Firstly, the paper describes the patients’ disturbances of self-experience and body alienations manifested in acute phases of schizophrenia. Secondly, the paper examines the patients’ personal biographical milestones and consequently the acute episode is contextualized within the intersubjective scenario in which it manifested itself in each case. Thirdly, the patients’ life stories are analyzed from a clinical psychological perspective, meaningfully connecting symptoms and life-world. Finally, it will be argued that the intersubjective dimension of the patients’ life stories shed light not only on the interpersonal processes involved in schizophrenia but also upon the psychotherapeutic treatment best suited to each individual case.

Assessing governance theory and practice in health-care organizations: a survey of UK hospices.
Chambers, Naomi; Benson, Lawrence; Boyd, Alan; Girling, Jeff
2012-05-01
This paper sets out a theoretical framework for analyzing board governance, and describes an empirical study of corporate governance practices in a subset of non-profit organizations (hospices in the UK). It examines how practices in hospice governance compare with what is known about effective board working. We found that key strengths of hospice boards included a strong focus on the mission and the finances of the organizations, and common weaknesses included a lack of involvement in strategic matters and a lack of confidence, and some nervousness about challenging the organization on the quality of clinical care. Finally, the paper offers suggestions for theoretical development particularly in relation to board governance in non-profit organizations. It develops an engagement theory for boards which comprises a triadic proposition of high challenge, high support and strong grip.
[Sex and gender: five challenges for epidemiologists].
Doyal, L
2004-03-01
This paper explores the challenges posed by sex and gender for epidemiologists as they try to integrate sex and gender concerns into their work in more appropriate and effective ways. The first challenge is one of conceptual clarification with considerable confusion still surrounding the use of the terms sex and gender themselves. The second challenge is to develop a broader understanding of the links between biological sex and health. The third challenge is to create a more comprehensive understanding of the ways in which social gender shapes the health of both women and men. The fourth challenge is to ensure that all research designs are both sex and gender sensitive. And the final challenge is to find a strategy for integrating findings on both sex and gender into wider equality agendas. This paper will examine each of these challenges in turn.
Human factor implications of the Eurocopter AS332L-1 Super Puma cockpit
NASA Technical Reports Server (NTRS)
Padfield, R. Randall
1993-01-01
The purpose of this paper is to identify and describe some of the human factor problems which can occur in the cockpit of a modern civilian helicopter. After examining specific hardware and software problems in the cockpit design of the Eurocopter (Aerospatiale) AS332L-1 Super Puma, the author proposes several principles that can be used to avoid similar human factors problems in the design of future cockpits. These principles relate to the use and function of warning lights, the design of autopilots in two-pilot aircraft, and the labeling of switches and warning lights, specifically with respect to abbreviations and translations from languages other than English. In the final section of the paper, the author describes current trends in society which he suggests should be taken into consideration when designing future aircraft cockpits.

The Global Fund is experiencing increased pressure to optimize results and improve its impact per dollar spent. It is also in transition from a provider of emergency funding, to a long-term, sustainable financing mechanism. This paper assesses the efficacy of current Global Fund investment and examines how health technology assessments (HTAs) can be used to provide guidance on the relative priority of health interventions currently subsidized by the Global Fund. In addition, this paper identifies areas where the application of HTAs can exert the greatest impact and proposes ways in which this tool could be incorporated, as a routine component, into application, decision, implementation, and monitoring and evaluation processes. Finally, it addresses the challenges facing the Global Fund in realizing the full potential of HTAs. PMID:23965222
A perspective on the FAA approval process: Integrating rotorcraft displays, controls and workload
NASA Technical Reports Server (NTRS)
Green, David L.; Hart, Jake; Hwoschinsky, Peter
1993-01-01
The FAA is responsible for making the determination that a helicopter is safe for IFR operations in the National Airspace System (NAS). This involves objective and subjective evaluations of cockpit displays, flying qualities, procedures and human factors as they affect performance and workload. After all of the objective evaluations are completed, and all Federal Regulations have been met, FAA pilots make the final subjective judgement as to suitability for use by civil pilots in the NAS. The paper uses the flying qualities and pilot workload characteristics of a small helicopter to help examine the FAA pilot's involvement in this process. The result highlights the strengths of the process and its importance to the approval of new aircraft and equipments for civil IFR helicopter applications. The paper also identifies opportunities for improvement.

Inequalities, assessment and computer algebra
NASA Astrophysics Data System (ADS)
Sangwin, Christopher J.
2015-01-01
The goal of this paper is to examine single variable real inequalities that arise as tutorial problems and to examine the extent to which current computer algebra systems (CAS) can (1) automatically solve such problems and (2) determine whether students' own answers to such problems are correct. We review how inequalities arise in contemporary curricula. We consider the formal mathematical processes by which such inequalities are solved, and we consider the notation and syntax through which solutions are expressed. We review the extent to which current CAS can accurately solve these inequalities, and the form given to the solutions by the designers of this software. Finally, we discuss the functionality needed to deal with students' answers, i.e. to establish equivalence (or otherwise) of expressions representing unions of intervals. We find that while contemporary CAS accurately solve inequalities there is a wide variety of notation used.

This Colloquium examines the field of the Einstein, Podolsky, and Rosen (EPR) gedanken experiment, from the original paper of Einstein, Podolsky, and Rosen, through to modern theoretical proposals of how to realize both the continuous-variable and discrete versions of the EPR paradox. The relationship with entanglement and Bell’s theorem are analyzed, and the progress to date towards experimental confirmation of the EPR paradox is summarized, with a detailed treatment of the continuous-variable paradox in laser-based experiments. Practical techniques covered include continuous-wave parametric amplifier and optical fiber quantum soliton experiments. Current proposals for extending EPR experiments to massive-particle systems are discussed, including spin squeezing, atomic position entanglement, and quadrature entanglement in ultracold atoms. Finally, applications of this technology to quantum key distribution, quantum teleportation, and entanglement swapping are examined.

Telemetry capsules have existed since the 1950s and were used to measure temperature, pH or pressure inside the gastrointestinal (GI) tract. It was hoped that these capsules would replace invasive techniques in the diagnosis of function disorders in the GI tract. However, problems such as signal loss and uncertainty of the pills position limited their use in a clinical setting. In this paper, a review of the capabilities of MicroElectroMechanical Systems (MEMS) and thick film technology (TFT) for the fabrication of a wireless pressure sensing microsystem is presented. The circuit requirements and methods of data transfer are examined. The available fabrication methods for MEMS sensors are also discussed and examples of wireless sensors are given. Finally the limitations of each technology are examined.

The toll of tobacco use on a pulmonary practice is severe. Physicians, patients, and their families experience frustration, hopelessness and even anger when confronted with a seemingly irrational decision to keep smoking despite morbid lung disease. This paper examines the biological basis of this behavior and seeks to integrate this insight into a rational approach to the problem in practice. Smoking is reexamined within the framework of an irrational compulsion to seek nicotine, despite a rational desire to stop. Control over the compulsion to smoke is established as an important clinical outcome, and the rationale for treating tobacco dependence as a chronic illness is examined. Finally, practical insights into managing ambivalence, including an aggressive pharmacotheapeutic approach based on the neurobiology, are presented. PMID:22707873
Human Factors and Ergonomics for the Dental Profession.
Ross, Al
2016-09-01
This paper proposes that the science of Human Factors and Ergonomics (HFE) is suitable for wide application in dental education, training and practice to improve safety, quality and efficiency. Three areas of interest are highlighted. First it is proposed that individual and team Non-Technical Skills (NTS), such as communication, leadership and stress management can improve error rates and efficiency of procedures. Secondly, in a physically and technically challenging environment, staff can benefit from ergonomic principles which examine design in supporting safe work. Finally, examination of organizational human factors can help anticipate stressors and plan for flexible responses to multiple, variable demands, and fluctuating resources. Clinical relevance: HFE is an evidence-based approach to reducing error rates and procedural complications, and avoiding problems associated with stress and fatigue. Improved teamwork and organizational planning and efficiency can impact directly on patient outcomes.

A discussion of new coal chemistry is presented. The chemical and physical structure of coal is examined in the first section, including structural studies of coal extracts, metal and metal complexes in coal and coal microporosity. The second section presents new advances in applied coal technology. The development of liquid fuels and chemicals from coal is given especial emphasis, with papers on the Sasol Synthol process, the Shell-Koppers gasification process, liquefaction and gasification in Germany, the Solvent Refined Coal process, the Exxon Donor Solvent liquefaction process and the Mobil Methanol-to-Gasoline process. Finally, some developments that will be part of the future of coal chemistry in the year 2000 are examined in the third section, including coal-based chemical complexes and the use of coal as an alternative source to oil for chemical feedstocks.
Pretest online discussion groups to augment teaching and learning.
Kuhn, Jonathan; Hasbargen, Barbara; Miziniak, Halina
2010-01-01
Tests and final examination scores of three semesters of control students in a nursing foundation course were compared with tests and final examination scores of three semesters of participating students. Participating students were offered access to an asynchronous pretest online discussion activity with a faculty e-moderator. While the simplified Bloom's revised taxonomy assisted in creating appropriate preparatory test and final examination questions for pretest online discussion, Salmon's five-stage online method provided direction to the e-moderator on how to encourage students to achieve Bloom's higher-order thinking skills during the pretest online discussions. Statistical analysis showed the pretest online discussion activity had a generally positive impact on tests and final examination scores, when controlling for a number of possible confounding variables, including instructor, cumulative grade point average, age, and credit hours.

Within this paper, control-relevant vehicle design concepts are examined using a widely used 3 DOF (plus flexibility) nonlinear model for the longitudinal dynamics of a generic carrot-shaped scramjet powered hypersonic vehicle. Trade studies associated with vehicle/engine parameters are examined. The impact of parameters on control-relevant static properties (e.g. level-flight trimmable region, trim controls, AOA, thrust margin) and dynamic properties (e.g. instability and right half plane zero associated with flight path angle) are examined. Specific parameters considered include: inlet height, diffuser area ratio, lower forebody compression ramp inclination angle, engine location, center of gravity, and mass. Vehicle optimizations is also examined. Both static and dynamic considerations are addressed. The gap-metric optimized vehicle is obtained to illustrate how this control-centric concept can be used to "reduce" scheduling requirements for the final control system. A classic inner-outer loop control architecture and methodology is used to shed light on how specific vehicle/engine design parameter selections impact control system design. In short, the work represents an important first step toward revealing fundamental tradeoffs and systematically treating control-relevant vehicle design.
Test anxiety: a cross-cultural perspective.
Bodas, Jaee; Ollendick, Thomas H
2005-03-01
The present paper examines test anxiety from a cross-cultural perspective with specific reference to the Indian and American cultures. The construct of test anxiety has been examined in many cultures all over the world. In this review, the importance of understanding and incorporating contextual factors in cross-cultural research is emphasized. Moreover, some of the methodological issues related to investigating culture-behavior relationship are discussed. Specifically, the derived-etic approach for conducting cross-cultural research is espoused. Then, research findings from western, cross-cultural, and Indian studies on test anxiety are reviewed. Consistent with the individualistic orientation of the western society, much of the research in the western world has adopted a de-contextualized approach. Inasmuch as many of the cross-cultural and Indian studies on test anxiety have their roots in western research, they have ignored the cultural context as well. To address this void, contextual variables relevant to test anxiety in the Indian setting are examined and hypotheses regarding the nature of test anxiety in Indian children are proposed. Finally, a research agenda is presented to examine these hypotheses using a derived-etic approach.

Assessing nurses' practical capability was a challenge in the past as it is today. In 1901 New Zealand established state registration of nurses, with a standardised three-year hospital-based training system and state final examinations. Nurses' practical capability was assessed in an oral and practical examination and in general nursing questions in written medical and surgical nursing papers. This historical research identifies the practical component of nursing assessed in these examinations, categorising it as nursing the patient, the room and the doctor. It considers changes in the nursing profession's view, 1900-1945, of the best way to assess nurses' practical capability. This shifted from the artificial setting of the oral and practical examination held by doctors and matrons, to a process of senior nurses assessing candidates in the more realistic setting of a ward. The research also considers whether the nursing or medical profession defined nursing practice. By the end of the time period, the nursing profession was claiming for itself the right to both determine and assess the practical component of nursing. Copyright © 2010 Elsevier Ltd.

Health promotion programs (HPP) and employee assistance programs (EAP) are compared in terms of their structure and process. Two common themes are extracted: a belief that both are beneficial to both employers and employees, and a sense of 'mission'. The technology of HPP and EAP are examined and compared. EAPs' stimulation from Federal funding is contrasted with the more indigenous roots of HPPs. Examination of empirical data comparing organizations with EAPs which have and have not adopted HPPs indicate the former tend to be somewhat more 'caring' toward employees. An examination of program ingredients indicates much greater commonality of structural and processual ingredients within EAPs as compared to HPPs. The extent to which each program type has become more 'populist' in orientation and the implications of these changes for program technology are considered. Finally the paper describes differences in program evaluation stemming from target group definitions in the two types of programs.
Beyond Currents: The Next Phase in GOCE Oceanographic Research
NASA Astrophysics Data System (ADS)
Bingham, Rory J.; Haines, Keith; Hughes, Chris W.
2015-03-01
GOCE has mapped the surface currents of the world’s oceans in unprecedented detail. What is now required is a concerted effort by the oceanographic community to go beyond currents and exploit these measurements for societal benefit. The aim of this review paper is to explore the ways in which this may be achieved, particularly in relation to ocean modelling. With the final gravity models now released, we begin by reviewing the progress GOCE has in made in measuring the ocean’s mean dynamic topography and associated ocean currents. In the light of this progress, we then examine the important oceanographic questions and technical challenges of societal relevance that can potentially be addressed with the help of the observations GOCE has delivered and outline the benefits their solution could deliver. Benefits may either be direct, through, for example, improved ocean modelling and operational forecasting, or indirect through improved understanding of particular oceanographic processes, such as heat transport by the Atlantic meridional overturning circulation or sea level change. Next we consider the technical challenges that must be overcome in bringing GOCE to bear on these problems. In particular we examine how best to use GOCE error information, this being an especially uncertain, underdeveloped and challenging area of investigation, due largely to the fact that such information has not been previously available to the user community. Finally, we consider measures of success; that is, metrics that can be used to quantify any GOCE-enabled progress that the community makes towards answering these questions. Such metrics are essential for demonstrating progress. Ultimately, with this review paper, we aim to paint a road map that will act as an impetus to the oceanography community to exploit the yet untapped potential of GOCE for scientific understanding and societal benefit.
Nonlinear Legendre Spectral Finite Elements for Wind Turbine Blade Dynamics: Preprint

Wang, Q.; Sprague, M. A.; Jonkman, J.
2014-01-01
This paper presents a numerical implementation and examination of new wind turbine blade finite element model based on Geometrically Exact Beam Theory (GEBT) and a high-order spectral finite element method. The displacement-based GEBT is presented, which includes the coupling effects that exist in composite structures and geometric nonlinearity. Legendre spectral finite elements (LSFEs) are high-order finite elements with nodes located at the Gauss-Legendre-Lobatto points. LSFEs can be an order of magnitude more efficient that low-order finite elements for a given accuracy level. Interpolation of the three-dimensional rotation, a major technical barrier in large-deformation simulation, is discussed in the context ofmore » LSFEs. It is shown, by numerical example, that the high-order LSFEs, where weak forms are evaluated with nodal quadrature, do not suffer from a drawback that exists in low-order finite elements where the tangent-stiffness matrix is calculated at the Gauss points. Finally, the new LSFE code is implemented in the new FAST Modularization Framework for dynamic simulation of highly flexible composite-material wind turbine blades. The framework allows for fully interactive simulations of turbine blades in operating conditions. Numerical examples showing validation and LSFE performance will be provided in the final paper.« less

Arguments made by those in favour of the legalisation of physician-assisted suicide (PAS) and euthanasia often rely upon the idea of the quality of life. This idea states that an individual's life is not valuable as an intrinsic good, but is only good based upon the things which it allows us to do. It thus allows the argument that it is morally permissible to kill individuals whose lives have fallen below an acceptable 'quality of life.' However, this concept may require that one accept the killing of individuals who have not expressly request to be killed such as severely disabled newborns. This paper will examine the issue of whether those who utilise a quality of life approach to justify the legalisation of PAS and euthanasia must logically accept the policy of killing severely disabled newborn children. First, there will be an examination of the concept of quality of life and its importance in the arguments for the legalisation of PAS or euthanasia. This paper will then consider how notions of personhood interact with the concept of quality of life in order to create the problem faced by those who favour the legalisation of PAS or euthanasia. Finally, this paper will consider how the notion of autonomy may be used as a way to avoid this difficulty created by the quality of life approach.
Simple Versus Elaborate Feedback in a Nursing Science Course

Elder, Betty L.; Brooks, David W.
2008-08-01
Feedback techniques, including computer-assisted feedback, have had mixed results in improving student learning outcomes. This project addresses the effect of type of feedback, simple or elaborate, for both short-term comprehension and long-term outcomes. A sample of 75 graduate nursing students was given a total of ten examinations. Four examinations provided tutorials in which the students received one of two types of feedback, simple or elaborate. Five examinations provided tutorials with no feedback. A comprehensive final examination compared initial content and final scores. This study found no significant differences between the types of feedback the students received. The mean scores were significantly higher on the four examinations where the students received feedback than on the five examinations with no feedback on tutorials. The comparison between the individual examinations and the similar content portion of the final examination indicated a significant drop in each of the four examinations where feedback was given and a significant improvement in four of the five examinations where no feedback was given.

Little is known about the predictors of symptom change or the methods that might increase user 'compliance' on websites designed to improve mental health outcomes. The present paper: (i) examines predictors of expected final depression and anxiety scores on the MoodGYM website as a function of user characteristics; and (ii) compares the compliance rates of the original site with the new public version of the site (MoodGYM Mark II). The latter site requires compulsory completion of 'core' online assessments and may increase completion of site questionnaires. MoodGYM Mark I participants were 19,607 visitors (public registrants) between April 2001 and September 2003 plus 182 participants who had been randomly assigned to MoodGYM in an earlier trial (The BlueMood Trial). MoodGYM Mark II participants were 38,791 public registrants of the MoodGYM Mark II site collected between September 2003 and October 2004. Symptom assessments are repeated within the website intervention to allow the examination of change in symptoms. Outcome variables were gender, initial depression severity scores, number of assessments completed and final anxiety and depression scores. Men are predicted to be 0.19 units (SE=0.095) higher than women on depression, controlling for the initial depression level and number of modules completed. For initial depression scores above 2, it is predicted that the final score will indicate improvement relative to the initial score, the magnitude of the improvement increasing as a function of the number of modules attempted. For initial anxiety scores above 2, it is predicted that the final score will indicate improvement relative to the initial score, the magnitude of the improvement increasing as a function of the number of modules attempted. Mark II registrants were more likely than to Mark I registrants to complete onsite assessments. Visitors to the MoodGYM site are likely to have better psychological outcomes if they complete more of the site material. Compulsory completion of core sections increases assessment completion. There is a need to examine further the significance of attrition from online interventions, to develop methods of handling missing data, and to investigate strategies to improve visitor dropout.

Epidemiologic research often relies on existing data, collected for nonepidemiologic reasons, to support studies. Data are obtained from hospital records, police reports, labor reports, death certificates, or other sources. Medical examiner/coroner records are, however, not often used in epidemiologic studies. The National Institute for Occupational Safety and Health's Division of Safety Research has begun using these records in its research program on work-related trauma. Because medical examiners and coroners have the legal authority and responsibility to investigate all externally caused deaths, these records can be used in surveillance of these deaths. Another use of these records is to validate cases identified by other case ascertainment methods, such as death certificates. Using medical examiner/coroner records also allows rapid identification of work-related deaths without waiting several years for mortality data from state offices of vital statistics. Finally, the records are an invaluable data source since they contain detailed information on the nature of the injury, external cause of death, and results of toxicologic testing, which is often not available from other sources. This paper illustrates some of the ways that medical examiner/coroner records are a valuable source of information for epidemiologic studies and makes recommendations to improve their usefulness.

Student participation is important for the success of active learning strategies, but participation is often linked to the level of preparation. At our institution, we use two types of active learning activities, a modified case-based learning exercise called active learning groups (ALG) and team-based learning (TBL). These strategies have different assessment and incentive structures for participation. Non-cognitive skills are assessed in ALG using a subjective five-point Likert scale. In TBL, assessment of individual student preparation is based on a multiple choice quiz conducted at the beginning of each session. We studied first-year medical student participation and performance in ALG and TBL as well as performance on course final examinations. Student performance in TBL, but not in ALG, was strongly correlated with final examination scores. Additionally, in students who performed in the upper 33rd percentile on the final examination, there was a positive correlation between final examination performance and participation in TBL and ALG. This correlation was not seen in students who performed in the lower 33rd percentile on the final examinations. Our results suggest that assessments of medical knowledge during active learning exercises could supplement non-cognitive assessments and could be good predictors of performance on summative examinations.
On Darwin's 'metaphysical notebooks'. II: "Metaphysics" and final cause.
Calabi, L
2001-01-01
The first part of this paper was published in Rivista di Biologia/Biology Forum 94 (2001). In the second part below an examination is made of the meaning of the term Metaphysics in some passages of the Darwinian Notebooks for the years 1836-1844. Metaphysics no longer defines a field of philosophical enquiries mainly concerning the being and the essence after the manner of Aristotle; it now refers to a kind of philosophy of mind after the manner of J. Locke's criticism of the Hypokeimenon. However Aristotle's Metaphysics also encompasses a treatment of the idea of causes, and of final cause particularly, in the explanation of events, and in the explanation of natural phenomena especially. The criticism of the idea of final cause in the interpretation of the world of life is one of Darwin's foundational acts in his early years. When conceiving his Système du monde, in the last years of the XVIII Century, Laplace could think that God is a hypothesis not really needed by science, as we are told. For the knowledge of organic nature to attain the status of science, it remained to be shown that since--certain of the exemplariness of Newton's Principles as much as cautious before the mystery of life--did not need the hypothesis of final ends in order to understand and explain the productions of the living nature: not only in the form of that final cause (the First Cause, the Vera Causa) in which Natural Theology still rested, but also in the form of nature's inner finality which still moulded Whewell's Kantian philosophy. Such demonstration is a very important subject in Darwin's early enquiries, where he criticises finalism as a projection of self-conceiving Man, likely inherited from a knowing of causality in nuce to be found also in animals.

This paper presents the results of 3-D hybrid simulations of Martian solar wind interaction containing the Martian crustal fields., self-consistent ionospheric chemistry and planetary rotation. It has already been reported that the addition of the crustal fields and planetary rotation makes a significant modification of the ionospheric loss from Mars, Brecht et al., 2016. This paper focuses on two other aspects of the interaction, the electric fields and the current systems created by the solar wind interaction. The results of several simulations will be analyzed and compared. The electric fields around Mars due to its interaction with the solar wind will be examined. Special attention will be paid to the electric field constituents (∇ X B, ∇Pe, ηJ). Regions where the electric field is parallel to the magnetic field will be found and the implications of these regions will be discussed. Current systems for each ion species will be shown. Finally the effects on the electric fields and the current systems due to the rotation of Mars will be examined.

This paper presents a research method for assessing stress and mental health in ongoing population-based social surveys that combines self-reports of naturally occurring daily stressors with a primary marker of stress physiology, salivary cortisol. We first discuss the relevance of stress processes to mental health and introduce a model for examining daily stress processes, which highlights multiple components of daily stressor exposure. A primary aim of this approach is to capture variability across stressful situations, between persons of different groups, or within persons over a period of time. Next, we describe how the assessment of diurnal salivary cortisol is a promising approach to examining naturally occurring stress physiology in large social surveys. We then present findings from the National Study of Daily Experiences (a substudy of the Midlife in the United States Study) that document the feasibility and reliability of the collection of daily stressors and salivary diurnal cortisol and provide examples of research findings linking stressor exposure to diurnal cortisol. The final portion of the paper describes ways that this approach can leverage the strengths of various features of longitudinal social surveys to extend research on stress and mental health.

This paper validates a previously introduced scalable modular control architecture and shows how it can be used to implement research equipment. The validation is conducted by presenting different kinds of micromanipulation applications that use the architecture. Conditions of the micro-world are very different from those of the macro-world. Adhesive forces are significant compared to gravitational forces when micro-scale objects are manipulated. Manipulation is mainly conducted by automatic control relying on haptic feedback provided by force sensors. The validated architecture is a hierarchical layered hybrid architecture, including a reactive layer and a planner layer. The implementation of the architecture is modular, and the architecture has a lot in common with open architectures. Further, the architecture is extensible, scalable, portable and it enables reuse of modules. These are the qualities that we validate in this paper. To demonstrate the claimed features, we present different applications that require special control in micrometer, millimeter and centimeter scales. These applications include a device that measures cell adhesion, a device that examines properties of thin films, a device that measures adhesion of micro fibers and a device that examines properties of submerged gel produced by bacteria. Finally, we analyze how the architecture is used in these applications.

The present study aims to investigate how resource strategies, which intend to reduce waste and increase recycling, influence on human exposure to hazardous chemicals from material recycling. In order to examine the flows of hazardous chemicals in recycled material, a mass flow analysis of plastics and paper at European level, including the flow of phthalates, i.e. di(2-ethylhexyl) phthalate (DEHP), di-n-butyl phthalate (DBP), and benzyl-butyl phthalate (BBP), has been performed. The result for the year 2012 shows that 26% of plastic wastes and 60% of paper consumed in Europe were recycled. This corresponds to the finding that approximately 4% of DEHP and BBP and 18% of DBP annual demands in Europe as raw material re-enter the product cycle with recycled plastics and paper. To examine the potential contribution of the phthalate exposure through recycled plastics and paper, a case study assessing the childhood exposures to phthalates from foods packed in recycled paper and plastics has been performed for 2-year-old children in Denmark. The result verifies that an increase in recycled paperboard and PET bottles in food packaging material causes a significant increase in childhood exposure to DBP corresponding to an additional exposure of 0.116-0.355 μg/kg bw/day; up to 18% of the total DBP exposure in Danish 2-year-olds. While most of the DEHP exposure can be explained, more than 50% of DBP and 70% of BBP exposure sources still remain to be identified. Finally, a conceptual framework for a circular economy based on sustainable and clean resource flows is proposed in order to increase material recycling without increasing adverse health effects.

Polymer stress tensor in turbulent shear flows.
L'vov, Victor S; Pomyalov, Anna; Procaccia, Itamar; Tiberkevich, Vasil
2005-01-01
The interaction of polymers with turbulent shear flows is examined. We focus on the structure of the elastic stress tensor, which is proportional to the polymer conformation tensor. We examine this object in turbulent flows of increasing complexity. First is isotropic turbulence, then anisotropic (but homogenous) shear turbulence, and finally wall bounded turbulence. The main result of this paper is that for all these flows the polymer stress tensor attains a universal structure in the limit of large Deborah number De > 1. We present analytic results for the suppression of the coil-stretch transition at large Deborah numbers. Above the transition the turbulent velocity fluctuations are strongly correlated with the polymer's elongation: there appear high-quality "hydroelastic" waves in which turbulent kinetic energy turns into polymer potential energy and vice versa. These waves determine the trace of the elastic stress tensor but practically do not modify its universal structure. We demonstrate that the influence of the polymers on the balance of energy and momentum can be accurately described by an effective polymer viscosity that is proportional to the cross-stream component of the elastic stress tensor. This component is smaller than the streamwise component by a factor proportional to De2. Finally we tie our results to wall bounded turbulence and clarify some puzzling facts observed in the problem of drag reduction by polymers.

Previous studies have observed inconsistent relations between the acuity of the Approximate Number System (ANS) and mathematical achievement. In this paper, we hypothesize that the relation between ANS acuity and mathematical achievement is influenced by fluency; that is, the mathematical achievement test covering a greater expanse of mathematical fluency may better reflect the relation between ANS acuity and mathematics skills. We explored three types of mathematical achievement tests utilized in this study: Subtraction, graded, and semester-final examination. The subtraction test was designed to measure the mathematical fluency. The graded test was more fluency-based than the semester-final examination, but both involved the same mathematical knowledge from the class curriculum. A total of 219 fifth graders from primary schools were asked to perform all three tests, then given a numerosity comparison task, a visual form perception task (figure matching), and a series of other tasks to assess general cognitive processes (mental rotation, non-verbal matrix reasoning, and choice reaction time). The findings were consistent with our expectations. The relation between ANS acuity and mathematical achievement was particularly clearly reflected in the participants’ performance on the visual form perception task, which supports the domain-general explanations for the underlying mechanisms of the relation between ANS acuity and math achievement.

E-service learning: A pedagogic innovation for healthcare management education.
Malvey, Donna M; Hamby, Eileen F; Fottler, Myron D
2006-01-01
This paper proposes an innovation in service learning that we identify as e-service learning. By adding the "e" to service learning, we create a service learning model that is dynamic, mediated by technology, and delivered online. This paper begins by examining service learning, which is a distinct learning concept. Service learning furnishes students with opportunities for applied learning through participation in projects and activities in community organizations. The authors then define and conceptualize e-service learning, including the anticipated outcomes of implementation such as enhanced access, quality, and cost effectiveness of healthcare management education. Because e-service learning is mediated by technology, we identify state of the art technologies that support e-service learning activities. In addition, possible e-service learning projects and activities that may be included in healthcare management courses such as finance, human resources, quality, service management/marketing and strategy are identified. Finally, opportunities for future research are suggested.

In conjunction with the recent critical assessments of the life and work of R.D. Laing, this paper seeks to demonstrate what is revealed when Laing’s work on families and created spaces of mental health care are examined through a geographical lens. The paper begins with an exploration of Laing’s time at the Tavistock Clinic in London during the 1960s, and of the co-authored text with Aaron Esterson entitled, Sanity, Madness and the Family (1964). The study then seeks to demonstrate the importance Laing and his colleague placed on the time-space situatedness of patients and their worlds. Finally, an account is provided of Laing’s and Esterson’s spatial thinking in relation to their creation of both real and imagined spaces of therapeutic care. PMID:25114145
The missing link in preconceptional care: the role of comparative effectiveness research.
Salihu, Hamisu M; Salinas, Abraham; Mogos, Mulubrhan
2013-07-01
This paper discusses an important element that is missing from the existing algorithm of preconception care, namely, comparative effectiveness research (CER). To our knowledge, there has been limited assessment of the comparative effectiveness of diverse interventions that promote preconception health, conditions under which these are most effective, for which particular populations, and their comparative costs. CER can improve the decision making process for the funding, development, implementation, and evaluation of comprehensive preconception care programs, specifically by identifying the most effective interventions with acceptable costs to society. This paper will examine the framework behind preconception care and how the inclusion of comparative effectiveness research and evaluation into the existing algorithm of preconception care could foster improvement in maternal and child health. We discuss challenges and opportunities regarding the utilization of CER in the decision making process in preconception health, and finally, we provide recommendations for future directions.

Rockman, Seth
This forum opens a conversation between the history of technology and the history of capitalism by considering the "paper technologies of capitalism" of the seventeenth, eighteenth, and nineteenth centuries in England and the United States. Seth Rockman offers an overview, connecting a recent exhibition of quotidian business ephemera to scholarly efforts to historicize the economic past, to engage material artifacts as things, and to embed the production of social knowledge in communities of practice. Three essays follow: William Deringer considers the "computational technologies" available in England to calculate future values; Caitlin Rosenthal traces the "rule of three" in the everyday transactions of the "innumerate" in the U.S. Early Republic; Jonathan Senchyne examines the materiality of paper within the emerging "rags to riches" tropes of nineteenth-century capitalist culture. Finally, Barbara Hahn concludes the forum with reflections of the overlapping terrain of the history of technology and the history of capitalism.
Co-design of RAD and ETHICS methodologies: a combination of information system development methods

Nasehi, Arezo; Shahriyari, Salman
2011-12-01
Co-design is a new trend in the social world which tries to capture different ideas in order to use the most appropriate features for a system. In this paper, co-design of two information system methodologies is regarded; rapid application development (RAD) and effective technical and human implementation of computer-based systems (ETHICS). We tried to consider the characteristics of these methodologies to see the possibility of having a co-design or combination of them for developing an information system. To reach this purpose, four different aspects of them are analyzed: social or technical approach, user participation and user involvement, job satisfaction, and overcoming change resistance. Finally, a case study using the quantitative method is analyzed in order to examine the possibility of co-design using these factors. The paper concludes that RAD and ETHICS are appropriate to be co-designed and brings some suggestions for the co-design.
Troubling the proletarianization of Mexican immigrant students in an era of neoliberal immigration

Choudry, Aziz
2010-06-01
In response to Richardson Bruna's "Mexican immigrant transnational social capital and class transformation: examining the role of peer mediation in insurgent science", this paper draws on the author's research on organizing, mobilization and knowledge production among adult im/migrant workers in Canada. While appreciative of the content and concerns of Richardson Bruna's argument, the paper argues for a clearer position on tensions between agency and structure, and class and capitalist social relations in which to contextualize the schooling of immigrant children in today's US classrooms. In addition, it explores some implications of Mignolo's (2000) work on the geohistory of knowledge, notably his concept of `border thinking' for teachers, teacher education, and curricula. Finally, the article suggests the potential of methodological frameworks and approaches of institutional ethnography (Smith 1987), political activist ethnography (Frampton et al. 2006) and global ethnography (Burawoy 2000) to inform research into this field.
Some New Sets of Sequences of Fuzzy Numbers with Respect to the Partial Metric
Ozluk, Muharrem
2015-01-01
In this paper, we essentially deal with Köthe-Toeplitz duals of fuzzy level sets defined using a partial metric. Since the utilization of Zadeh's extension principle is quite difficult in practice, we prefer the idea of level sets in order to construct some classical notions. In this paper, we present the sets of bounded, convergent, and null series and the set of sequences of bounded variation of fuzzy level sets, based on the partial metric. We examine the relationships between these sets and their classical forms and give some properties including definitions, propositions, and various kinds of partial metric spaces of fuzzy level sets. Furthermore, we study some of their properties like completeness and duality. Finally, we obtain the Köthe-Toeplitz duals of fuzzy level sets with respect to the partial metric based on a partial ordering. PMID:25695102
A Simple Method for Causal Analysis of Return on IT Investment
Alemi, Farrokh; Zargoush, Manaf; Oakes, James L.; Edrees, Hanan
2011-01-01
This paper proposes a method for examining the causal relationship among investment in information technology (IT) and the organization's productivity. In this method, first a strong relationship among (1) investment in IT, (2) use of IT and (3) organization's productivity is verified using correlations. Second, the assumption that IT investment preceded improved productivity is tested using partial correlation. Finally, the assumption of what may have happened in the absence of IT investment, the so called counterfactual, is tested through forecasting productivity at different levels of investment. The paper applies the proposed method to investment in the Veterans Health Information Systems and Technology Architecture (VISTA) system. Result show that the causal analysis can be done, even with limited data. Furthermore, because the procedure relies on overall organization's productivity, it might be more objective than when the analyst picks and chooses which costs and benefits should be included in the analysis.

Saryazdi, M. D.; Homaei, N.; Arjmand, A.
2018-05-01
In developed countries, people have learned to follow efficient consumption patterns, while in developing countries, such as Iran, these patterns are not well executed. A large amount of energy is almost consumed in buildings and houses and though the consumption patterns varies in different societies, various energy policies are required to meet the consumption challenges. So far, several papers and more than ten case studies have worked on the relationship between domestic energy consumption and urban development, however these researches did not analyzed the impact of energy consumption on urban development. Therefore, this paper attempts to examine the interactions between the energy consumption and urban development by using system dynamics as the most widely used methods for complex problems. The proposed approach demonstrates the interactions using causal loop and flow diagrams and finally, suitable strategies will be proposed for urban development through simulations of different scenarios.
A low carbon economy and society.
Urry, John
2013-03-13
This paper examines various aspects of moving from high carbon economies and societies to a cluster of low carbon systems. First, some historical material is considered from the Second World War and the 1970s, periods with some lessons for the contemporary 'powering down' of whole societies. Second, analysis is provided of some green shoots of a powering down of existing systems identifiable in the contemporary developed world. Third, analysis is provided of the array of systems, social practices and innovations that would have to develop in order to effect powering down on a sufficient scale and within an appropriate time period. Most examples are drawn from transport and mobility. Finally, the paper demonstrates just why developing new systems is so hard, especially as this must involve a transformed cluster of systems. The forces that make a new cluster unlikely are exceptionally powerful and make this a very difficult but not impossible outcome.

Medical dominance in Italy: a partial decline.
Tousijn, Willem
2002-09-01
In the last three decades, a number of changes in health systems has been challenging medical dominance in many countries. It has been widely debated whether the medical profession has been able to cope with these changes and maintain its power or, rather, has been deprofessionalised or proletarianised. In this paper, the effects of these changes in Italy are examined, by using a multi-dimensional concept of medical dominance. As a result of this analysis. medical dominance in Italy is depicted as declining on some dimensions while changing its nature on others. The final part of the paper discusses some current explanations of this trend and suggests that the transition to post-modern society and the "late modernity" argument (Giddens, 1990; The consequences of modernity, Polity Press, Cambridge; Beck, 1992; Risk society: towards a new modernity, Sage, London) may provide an entry into more adequate explanations.
Text-based plagiarism in scientific publishing: issues, developments and education.
Li, Yongyan
2013-09-01
Text-based plagiarism, or copying language from sources, has recently become an issue of growing concern in scientific publishing. Use of CrossCheck (a computational text-matching tool) by journals has sometimes exposed an unexpected amount of textual similarity between submissions and databases of scholarly literature. In this paper I provide an overview of the relevant literature, to examine how journal gatekeepers perceive textual appropriation, and how automated plagiarism-screening tools have been developed to detect text matching, with the technique now available for self-check of manuscripts before submission; I also discuss issues around English as an additional language (EAL) authors and in particular EAL novices being the typical offenders of textual borrowing. The final section of the paper proposes a few educational directions to take in tackling text-based plagiarism, highlighting the roles of the publishing industry, senior authors and English for academic purposes professionals.
Launch flexibility using NLP guidance and remote wind sensing

Cramer, Evin J.; Bradt, Jerre E.; Hardtla, John W.
1990-01-01
This paper examines the use of lidar wind measurements in the implementation of a guidance strategy for a nonlinear programming (NLP) launch guidance algorithm. The NLP algorithm uses B-spline command function representation for flexibility in the design of the guidance steering commands. Using this algorithm, the guidance system solves a two-point boundary value problem at each guidance update. The specification of different boundary value problems at each guidance update provides flexibility that can be used in the design of the guidance strategy. The algorithm can use lidar wind measurements for on pad guidance retargeting and for load limiting guidance steering commands. Examples presented in the paper use simulated wind updates to correct wind induced final orbit errors and to adjust the guidance steering commands to limit the product of the dynamic pressure and angle-of-attack for launch vehicle load alleviation.
The use of an essay examination in evaluating medical students during the surgical clerkship.
Smart, Blair J; Rinewalt, Daniel; Daly, Shaun C; Janssen, Imke; Luu, Minh B; Myers, Jonathan A
2016-01-01
Third-year medical students are graded according to subjective performance evaluations and standardized tests written by the National Board of Medical Examiners (NBME). Many "poor" standardized test takers believe the heavily weighted NBME does not evaluate their true fund of knowledge and would prefer a more open-ended forum to display their individualized learning experiences. Our study examined the use of an essay examination as part of the surgical clerkship evaluation. We retrospectively examined the final surgical clerkship grades of 781 consecutive medical students enrolled in a large urban academic medical center from 2005 to 2011. We examined final grades with and without the inclusion of the essay examination for all students using a paired t test and then sought any relationship between the essay and NBME using Pearson correlations. Final average with and without the essay examination was 72.2% vs 71.3% (P < .001), with the essay examination increasing average scores by .4, 1.8, and 2.5 for those receiving high pass, pass, and fail, respectively. The essay decreased the average score for those earning an honors by .4. Essay scores were found to overall positively correlate with the NBME (r = .32, P < .001). The inclusion of an essay examination as part of the third-year surgical core clerkship final did increase the final grade a modest degree, especially for those with lower scores who may identify themselves as "poor" standardized test takers. A more open-ended forum may allow these students an opportunity to overcome this deficiency and reveal their true fund of surgical knowledge. Copyright © 2016 Elsevier Inc. All rights reserved.

Landfill is still the main technological facility used to treat and dispose municipal solid waste (MSW) worldwide. In developing countries, final dumping is applied without environmental monitoring and soil protection since solid waste is mostly sent to open dump sites while, in Europe, landfilling is considered as the last option since reverse logistic approaches or energy recovery are generally encouraged. However, many regions within the European Union continue to dispose of MSW to landfill, since modern facilities have not been introduced owing to unreliable regulations or financial sustainability. In this paper, final disposal activities and pre-treatment operations in an area in southern Italy are discussed, where final disposal is still the main option for treating MSW and the recycling rate is still low. Mechanical biological treatment (MBT) facilities are examined in order to evaluate the organic stabilization practices applied for MSW and the efficiencies in refuse derived fuel production, organic waste stabilization and mass reduction. Implementing MBT before landfilling the environmental impact and waste mass are reduced, up to 30%, since organic fractions are stabilized resulting an oxygen uptake rate less than 1600 mgO 2 h -1 kg -1 VS , and inorganic materials are exploited. Based on experimental data, this work examines MBT application in contexts where recycling and recovery activities have not been fully developed. The evidence of this study led to state that the introduction of MBT facilities is recommended for developing regions with high putrescible waste production in order to decrease environmental pollution and enhance human healthy.

Marital instability and the economic status of women.
Hoffman, S
1977-02-01
This paper uses longitudinal data from the Panel Study of Income Dynamics to examine the relationship between changes in marital status and economic status. Differences between men and women and between whites and blacks are also considered. A major finding is that, after adjusting for changes in family size, the economic status of divorced or separated men improves, while that of women declines. Components of income change are discussed, with special emphasis on changes in the labor force and welfare status of women who were divorced or separated during the analysis period. Finally, data on the magnitude and distribution of alimony/child-support payments are presented.
Distraction: an assessment of smartphone usage in health care work settings

2012-01-01
Smartphone use in health care work settings presents both opportunities and challenges. The benefits could be severely undermined if abuse and overuse are not kept in check. This practice-focused research paper examines the current panorama of health software applications. Findings from existing research are consolidated to elucidate the level and effects of distraction in health care work settings due to smartphone use. A conceptual framework for crafting guidelines to regulate the use of smartphones in health care work settings is then presented. Finally, specific guidelines are delineated to assist in creating policies for the use of smartphones in a health care workplace. PMID:22969308

The wave digital filter patterned after doubly terminated maximum available power (MAP) networks by means of the Richard's transformation has been shown to have low-coefficient-sensitivity properties. This paper examines the exact nature of the relationship between the wave-digital-filter structure and the MAP networks and how the sensitivity property arises, which permits implementation of the digital structure with a lower coefficient word length than that possible with the conventional structures. The proper design procedure is specified and the nature of the unique complementary outputs is discussed. Finally, an example is considered which illustrates the design, the conversion techniques, and the low sensitivity properties.

Adaptive automation refers to technology that can change its mode of operation dynamically. Further, both the technology and the operator can initiate changes in the level or mode of automation. The present paper reviews research on adaptive technology. It is divided into three primary sections. In the first section, issues surrounding the development and implementation of adaptive automation are presented. Because physiological-based measures show much promise for implementing adaptive automation, the second section is devoted to examining candidate indices. In the final section, those techniques that show the greatest promise for adaptive automation as well as issues that still need to be resolved are discussed.
Post-PharmD Industry Fellowship Opportunities and Proposed Guidelines for Uniformity

2009-01-01
The focus of this paper is to examine the surge in the development of post-PharmD industry fellowships (ie, pharmacy fellowship programs sponsored by the biopharmaceutical or pharmaceutical industry). These post-PharmD training programs do not fit the currently accepted definition of a pharmacy fellowship; therefore, the authors propose a new and distinct definition to encompass these fellowships. The authors provide program examples to showcase the establishment of the post-PharmD industry fellowship institutional centers. Finally, the authors provide recommendations to create uniformity in the programs of this relatively new category of post-PharmD training. PMID:19513158

Mui, S. Y.; Modestino, J. W.
1977-01-01
The bit error probability performance of a differentially-coherent phase-shift keyed (DPSK) modem with convolutional encoding and Viterbi decoding on time-varying fading channels is examined. Both the Rician and the lognormal channels are considered. Bit error probability upper bounds on fully-interleaved (zero-memory) fading channels are derived and substantiated by computer simulation. It is shown that the resulting coded system performance is a relatively insensitive function of the choice of channel model provided that the channel parameters are related according to the correspondence developed as part of this paper. Finally, a comparison of DPSK with a number of other modulation strategies is provided.

Religion is one of the most powerful and ubiquitous forces in African American same-gender-loving (SGL) men's lives. Research indicates that it has both positive and negative influences on the health behaviors and outcomes of this population. This paper presents a review of the literature that examines religion as a risk and protective factor for African American SGL men. A strengths-based approach to religion that aims to utilize its protective qualities and weaken its relation to risk is proposed. Finally, recommendations are presented for the use of a strengths-based approach to religion in clinical work and research.
On Decision-Making Among Multiple Rule-Bases in Fuzzy Control Systems

Tunstel, Edward; Jamshidi, Mo
1997-01-01
Intelligent control of complex multi-variable systems can be a challenge for single fuzzy rule-based controllers. This class of problems cam often be managed with less difficulty by distributing intelligent decision-making amongst a collection of rule-bases. Such an approach requires that a mechanism be chosen to ensure goal-oriented interaction between the multiple rule-bases. In this paper, a hierarchical rule-based approach is described. Decision-making mechanisms based on generalized concepts from single-rule-based fuzzy control are described. Finally, the effects of different aggregation operators on multi-rule-base decision-making are examined in a navigation control problem for mobile robots.

Then, verification requirements are expressed in terms of an overall test philosophy for distributed computer systems. This test philosophy stems from previous experience that was gained with centralized systems (Apollo and the Space Shuttle), and deals directly with the new problems that verification of distributed systems may present. Finally, a description of potential hardware and software tools to help solve these problems is provided.

This paper gives an overview of micro-guidance and control technologies and in the process previews of the technology/user and systems issues presented in the guidance and control session at the workshop. We first present a discussion of the advantages of using micro-guidance and control components and then detail six micro-guidance and control thrusts that could have a revolutionary impact on space missions and systems. Specific technologies emerging in the micro-guidance and control field will be examined. These technologies fall into two broad categories: micro-attitude determination (inertial and celestial) and micro-actuation, control and sensing. Finally, the scope of the workshop's guidance and control panel are presented.
A psycho-endocrinological overview of transsexualism.
Michel, A; Mormont, C; Legros, J J
2001-10-01
The technical possibility of surgical sex change has opened up a debate concerning the legitimacy and utility of carrying out such an intervention at the request of the transsexual. Diagnostic, psychological, medical and ethical arguments have been brought forth, both for and against. Nonetheless, anatomical transformation by surgical means has currently become a practice as the frequency of serious gender identity disorders is constantly progressing. After a brief introduction, the present paper will consider typological, aetiological and epidemiological aspects of transsexualism. Treatment of the sex change applicant is then defined and discussed in terms of psychological, psychiatric, endocrinological and surgical aspects. Finally, the question of post-operation follow-up will be examined.

Evaluating students' performance only from overall examination marks does not give accurate evidence of their achievement on a particular subject. For a more detailed analysis, an instrument called Rasch Measurement Model (Rasch Model), widely used in education research, may be applied. Using the analysis map, the level of each student's ability and the level of the questions difficulty can be measured. This paper describes how the Rasch Model is used to evaluate students' achivement and performance in Vector, a subject taken by students enrolled in the Physical Science Program at the Centre for Foundation Studies in Science, University of Malaya. Usually, students' understanding of the subject and performance are assessed and examined at the end of the semester in the final examination, apart from continuous assessment done throughout the course. In order to evaluate the individual achievement and get a better and accurate evidence on the performance, 28 male and 28 female students' marks were taken randomly from the final examination results and analysed using the Rasch Model. Observation made from the map showed that more than half of the questions were categorized as difficult while the two most difficult questions could be answered correctly by 33.9% of the students. Results showed that the students performed very well and their achievement was above expectation. About 27% of the sudents could be considered as having very high ability in answering all the questions, with one student being able to answer well, obtaining perfect score. However, two students were found to be misfits since they were able to answer difficult questions but gave poor response to easy ones.

INTRODUCTION This paper reviews the work done in the ADNI PET core over the past 5 years, largely concerning techniques, methods, and results related to amyloid imaging in ADNI. METHODS The PET Core has utilized [18F]florbetapir routinely on ADNI participants, with over 1600 scans available for download. Four different laboratories are involved in data analysis, and have examined factors such as longitudinal florbetapir analysis, use of FDG-PET in clinical trials, and relationships between different biomarkers and cognition. RESULTS Converging evidence from the PET Core has indicated that cross-sectional and longitudinal florbetapir analyses require different reference regions. Studies have also examined the relationship between florbetapir data obtained immediately after injection, which reflects perfusion, and FDG-PET results. Finally, standardization has included the translation of florbetapir PET data to a centiloid scale. CONCLUSION The PET Core has demonstrated a variety of methods for standardization of biomarkers such as florbetapir PET in a multicenter setting. PMID:26194311

Different animal species have been used as proxies for human remains in decomposition studies for decades, although few studies have sought to validate their use in research aimed at estimating the postmortem interval. This study examines 45 pig, rabbit, and human subjects placed in three seasonal trials at the Anthropology Research Facility. In an earlier paper, we found that overall decomposition trends did vary between species that could be due to differential insect and scavenger behavior. This study specifically examines if scavenger behavior differs by carrion species. Daily photographs, game camera photographs, written observations, and Total Body Score (TBS) documented scavenging and decomposition changes. Results show that raccoons were the most commonly observed vertebrate scavenger, that scavenging was most extensive in winter, and that certain human subjects were preferred over other humans and all non-human subjects. Finally, scavenging activity greatly reduces the accuracy of postmortem interval estimates based on TBS. © 2018 American Academy of Forensic Sciences.
Ask your doctor: the construction of smoking in advertising posters produced in 1946 and 2004.
Street, Annette F
2004-12-01
This paper examines two full-page A3 poster advertisements in mass magazines produced at two time points over a 60-year period depicting smoking and its effects, with particular relation to lung cancer. Each poster represents the social and cultural milieu of its time. The writings of Foucault are used to explore the disciplinary technologies of sign systems as depicted in the two posters. The relationships between government, tobacco companies and drug companies and the technologies of production are examined with regard to the development of smoking cessation strategies. The technologies of power are associated with the constructions of risk and lifestyles. The technologies of the self locate smokers as culpable subjects responsible for their individual health. Finally, the meshing of these technologies places the doctor in the frame as "authoritative knower" and representative of expert systems.

This paper introduces urban land teleconnections as a conceptual framework that explicitly links land changes to underlying urbanization dynamics. We illustrate how three key themes that are currently addressed separately in the urban sustainability and land change literatures can lead to incorrect conclusions and misleading results when they are not examined jointly: the traditional system of land classification that is based on discrete categories and reinforces the false idea of a rural–urban dichotomy; the spatial quantification of land change that is based on place-based relationships, ignoring the connections between distant places, especially between urban functions and rural land uses; and the implicit assumptions about path dependency and sequential land changes that underlie current conceptualizations of land transitions. We then examine several environmental “grand challenges” and discuss how urban land teleconnections could help research communities frame scientific inquiries. Finally, we point to existing analytical approaches that can be used to advance development and application of the concept. PMID:22550174
An introduction to data reduction: space-group determination, scaling and intensity statistics.
Evans, Philip R
2011-04-01
This paper presents an overview of how to run the CCP4 programs for data reduction (SCALA, POINTLESS and CTRUNCATE) through the CCP4 graphical interface ccp4i and points out some issues that need to be considered, together with a few examples. It covers determination of the point-group symmetry of the diffraction data (the Laue group), which is required for the subsequent scaling step, examination of systematic absences, which in many cases will allow inference of the space group, putting multiple data sets on a common indexing system when there are alternatives, the scaling step itself, which produces a large set of data-quality indicators, estimation of |F| from intensity and finally examination of intensity statistics to detect crystal pathologies such as twinning. An appendix outlines the scoring schemes used by the program POINTLESS to assign probabilities to possible Laue and space groups.

Non-destructive eddy current testing (ECT) is widely used to examine structural defects in ferromagnetic pipe in the oil and gas industry. Implementation of giant magnetoresistance (GMR) sensors as magnetic field sensors to detect the changes of magnetic field continuity have increased the sensitivity of eddy current techniques in detecting the material defect profile. However, not many researchers have described in detail the structure and issues of GMR sensors and their application in eddy current techniques for nondestructive testing. This paper will describe the implementation of GMR sensors in non-destructive testing eddy current testing. The first part of this paper will describe the structure and principles of GMR sensors. The second part outlines the principles and types of eddy current testing probe that have been studied and developed by previous researchers. The influence of various parameters on the GMR measurement and a factor affecting in eddy current testing will be described in detail in the third part of this paper. Finally, this paper will discuss the limitations of coil probe and compensation techniques that researchers have applied in eddy current testing probes. A comprehensive review of previous studies on the application of GMR sensors in non-destructive eddy current testing also be given at the end of this paper. PMID:26927123

"Our Time is Up": A Relational Perspective on the Ending of a Single Psychotherapy Session.
Gans, Jerome S
2016-12-31
This paper, written from a relational perspective, examines the final minutes of an individual psychotherapy session, and is organized around the topics of boundary negotiation, unwitting self-disclosures, visual challenges, and countertransference. Attending to session-ending material is important because the separation involved lends heightened emotional intensity to the oftensignificant material that appears in the final minutes. This material often serves as a bridge to the psychotherapeutic work to be taken up in subsequent sessions. Session-ending dynamics call upon the therapist to prioritize empathy, validation, and support for the patient suffering from early deprivation; identify and heal narcissistic injury in the patient wishing to be special; judiciously alter the frame when doing so will benefit the patient and not constitute a boundary violation; avoid re-traumatization; admit mistakes; confront blatant denial; advance agency; address uncomfortable topics; set appropriate limits; and deal authentically with uncomfortable countertransference. Numerous clinical examples serve to illustrate these clinical phenomena.

In the field of metal rolling, the quality of the steel roller's surface is significant for the final rolling products, e.g. metal sheets or foils. Besides the dimensional accuracy and surface roughness, the optical uniformity of the roller surface is also required for high quality rolling application. The typical optical defects of rollers after finish grinding include speckles, chatter marks, feed traces, and combination of all above. Unlike surface roughness, the optical defects can hardly be characterized by the topography or scanning electrical microscope measurement. Only the inspection by bared eyes of experienced engineers appears to be the effective manner for surface optical defects examination for large steel rollers. In this paper, an on-site machine vision system is designed to add on to the roller grinding machine to capture the surface image, and then an improved optical defects segmentation algorithm is developed based on the active contour model. Finally, experiments are carried out to verify the efficacy of the improved model.
Additional EIPC Study Analysis. Final Report

Hadley, Stanton W; Gotham, Douglas J.; Luciani, Ralph L.
Between 2010 and 2012 the Eastern Interconnection Planning Collaborative (EIPC) conducted a major long-term resource and transmission study of the Eastern Interconnection (EI). With guidance from a Stakeholder Steering Committee (SSC) that included representatives from the Eastern Interconnection States Planning Council (EISPC) among others, the project was conducted in two phases. Phase 1 involved a long-term capacity expansion analysis that involved creation of eight major futures plus 72 sensitivities. Three scenarios were selected for more extensive transmission- focused evaluation in Phase 2. Five power flow analyses, nine production cost model runs (including six sensitivities), and three capital cost estimations weremore » developed during this second phase. The results from Phase 1 and 2 provided a wealth of data that could be examined further to address energy-related questions. A list of 14 topics was developed for further analysis. This paper brings together the earlier interim reports of the first 13 topics plus one additional topic into a single final report.« less

Prior studies showed that scientists' professional networks contribute to research productivity, but little work has examined what factors predict the formation of professional networks. This study sought to 1) examine what factors predict the formation of international ties between faculty and graduate students and 2) identify how these international ties would affect publication productivity in three East Asian countries. Face-to-face surveys and in-depth semi-structured interviews were conducted with a sample of faculty and doctoral students in life sciences at 10 research institutions in Japan, Singapore, and Taiwan. Our final sample consisted of 290 respondents (84 faculty and 206 doctoral students) and 1,435 network members. We used egocentric social network analysis to examine the structure of international ties and how they relate to research productivity. Our findings suggest that overseas graduate training can be a key factor in graduate students' development of international ties in these countries. Those with a higher proportion of international ties in their professional networks were likely to have published more papers and written more manuscripts. For faculty, international ties did not affect the number of manuscripts written or of papers published, but did correlate with an increase in publishing in top journals. The networks we examined were identified by asking study participants with whom they discuss their research. Because the relationships may not appear in explicit co-authorship networks, these networks were not officially recorded elsewhere. This study sheds light on the relationships of these invisible support networks to researcher productivity.

Introduction Whilst telesupervision (clinical supervision undertaken using communication technology) is being used more frequently, there is limited information on what factors influence its effectiveness and quality. We undertook this systematic review to address this gap. Methods Eligible telesupervision studies were identified following targeted search of electronic databases and the grey literature. Data were synthesised thematically, resulting in development of core themes. Results We identified 286 papers for initial relevancy screening by title and abstract. The full text of 36 papers were then retrieved and assessed for further relevance. A total of 11 papers were included in the final analysis. We identified eight themes that contribute to effective and high-quality telesupervision: supervisee characteristics, supervisor characteristics, supervision characteristics, supervisory relationship, communication strategies, prior face-to-face contact, environmental factors and technological considerations. Conclusion From the available evidence, telesupervision can be a feasible and acceptable form of clinical supervision if set up well. Further studies with robust designs are required to strengthen the existing evidence on what makes telesupervision effective, as well as to examine its cost-effectiveness.

This paper focuses on the use of information technology (IT) in diverse microsimulation studies and presents state-of-the-art solutions in the traditional application field of personal income tax simulation. The aim of the paper is to promote solutions, which can improve the efficiency and quality of microsimulation model implementation, assess their applicability and help to shift attention from microsimulation model implementation and data analysis towards experiment design and model use. First, the authors shortly discuss the relevant characteristics of the microsimulation application field and the managerial decision-making problem. After examination of the salient problems, advanced IT solutions, such as meta-database and service-oriented architecture are presented. The authors show how selected technologies can be applied to support both data- and behavior-driven and even agent-based personal income tax microsimulation model development. Finally, examples are presented and references made to the Hungarian Income Tax Simulator (HITS) models and their results. The paper concludes with a summary of the IT assessment and application-related author remarks dedicated to an Indonesian Income Tax Microsimulation Model.
Radical constructivism: Between realism and solipsism
NASA Astrophysics Data System (ADS)
Martínez-Delgado, Alberto
2002-11-01
This paper criticizes radical constructivism of the Glasersfeld type, pointing out some contradictions between the declared radical principles and their theoretical and practical development. These contradictions manifest themselves in a frequent oscillation between solipsism and realism, despite constructivist claims to be an anti-realist theory. The paper also points out the contradiction between the relativism of the radical constructivist principles and the constructivist exclusion of other epistemological or educational paradigms. It also disputes the originality and importance of the radical constructivist paradigm, suggesting the idea of an isomorphism between radical constructivist theory and contemplative realism. In addition, some pedagogical and scientific methodological aspects of the radical constructivist model are examined. Although radical constructivism claims to be a rational theory and advocates deductive thinking, it is argued that there is no logical deductive connection between the radical principles of constructivism and the radical constructivist ideas about scientific research and learning. The paper suggests the possibility of an ideological substratum in the construction and hegemonic success of subjective constructivism and, finally, briefly advances an alternative realist model to epistemological and educational radical constructivism.
Appetitive Pavlovian-instrumental Transfer: A review.
Cartoni, Emilio; Balleine, Bernard; Baldassarre, Gianluca
2016-12-01
Reward-related cues are an important part of our daily life as they often influence and guide our actions. This paper reviews one of the experimental paradigms used to study the effects of cues, the Pavlovian to Instrumental Transfer paradigm. In this paradigm, cues associated with rewards through Pavlovian conditioning alter motivation and choice of instrumental actions. The first transfer experiments date back to the 1940s, but only in the last decade has it been fully recognised that there are two types of transfer, specific and general. This paper presents a systematic review of both the neural substrates and the behavioral factors affecting both types of transfer. It also examines the recent application of the paradigm to study the effect of cues on human participants, both in normal and pathological conditions, and the interactions of transfer with drugs of abuse. Finally, the paper analyses the theoretical aspects of transfer to build an overall picture of the phenomenon, from early theories to recent hierarchical accounts. Copyright © 2016 The Authors.

Strategic information technology alliances for effective health-care supply chain management.
Shih, Stephen C; Rivers, Patrick A; Hsu, H Y Sonya
2009-08-01
To gain and sustain competitive advantage, health-care providers have to continuously review and renovate their operational and information technology (IT) strategies through collaborative and cooperative endeavour with their supply chain channel members. This paper explores new ways of enhancing a health-care organization's responsiveness to changes and increasing its competitiveness through implementing strategic information technology alliances among channel members in a health-care supply chain network. An overview of issues and problems (e.g. bullwhip effect, negative externalities and free-riding phenomenon in multichannel supply chains) presented in the health-care supply chains is first delineated. This paper further goes over the issues of health-care supply chain coordination and integration for strategic IT alliances, followed by the discussion of the spillover effect of IT investments. A number of viable IT practices (such as information sharing and Internet-enabled supply chain portal) for effective health-care supply chain collaboration and coordination are then examined in this research. Finally, the paper discusses how strategic IT alliances can help improve the effectiveness of health-care supply chain management.

This paper describes a rigorous yet flexible standard cell place-and-route flow that is used to quantify block-level power, performance, and area trade-offs driven by two unique cell architectures and their associated design rule differences. The two architectures examined in this paper differ primarily in their use of different power-distribution-networks to achieve the desired circuit performance for high-performance logic designs. The paper shows the importance of incorporating block-level routability experiments in the early phases of design-technology co-optimization by reviewing a series of routing trials that explore different aspects of the technology definition. Since the electrical and physical parameters leading to critical process assumptions and design rules are unique to specific integration schemes and design objectives, it is understood that the goal of this work is not to promote one cell-architecture over another, but rather to convey the importance of exploring critical trade-offs long before the process details of the technology node are finalized to a point where a process design kit can be published.
Temporal resolution and motion artifacts in single-source and dual-source cardiac CT.
Schöndube, Harald; Allmendinger, Thomas; Stierstorfer, Karl; Bruder, Herbert; Flohr, Thomas
2013-03-01
The temporal resolution of a given image in cardiac computed tomography (CT) has so far mostly been determined from the amount of CT data employed for the reconstruction of that image. The purpose of this paper is to examine the applicability of such measures to the newly introduced modality of dual-source CT as well as to methods aiming to provide improved temporal resolution by means of an advanced image reconstruction algorithm. To provide a solid base for the examinations described in this paper, an extensive review of temporal resolution in conventional single-source CT is given first. Two different measures for assessing temporal resolution with respect to the amount of data involved are introduced, namely, either taking the full width at half maximum of the respective data weighting function (FWHM-TR) or the total width of the weighting function (total TR) as a base of the assessment. Image reconstruction using both a direct fan-beam filtered backprojection with Parker weighting as well as using a parallel-beam rebinning step are considered. The theory of assessing temporal resolution by means of the data involved is then extended to dual-source CT. Finally, three different advanced iterative reconstruction methods that all use the same input data are compared with respect to the resulting motion artifact level. For brevity and simplicity, the examinations are limited to two-dimensional data acquisition and reconstruction. However, all results and conclusions presented in this paper are also directly applicable to both circular and helical cone-beam CT. While the concept of total TR can directly be applied to dual-source CT, the definition of the FWHM of a weighting function needs to be slightly extended to be applicable to this modality. The three different advanced iterative reconstruction methods examined in this paper result in significantly different images with respect to their motion artifact level, despite exactly the same amount of data being used in the reconstruction process. The concept of assessing temporal resolution by means of the data employed for reconstruction can nicely be extended from single-source to dual-source CT. However, for advanced (possibly nonlinear iterative) reconstruction algorithms the examined approach fails to deliver accurate results. New methods and measures to assess the temporal resolution of CT images need to be developed to be able to accurately compare the performance of such algorithms.

LHC vector resonance searches in the t\\overline{t}Z final state

LHC searches for BSM resonances in l + l - , jj, t\\overline{t} , γγ and VV final states have so far not resulted in discovery of new physics. Current results set lower limits on mass scales of new physics resonances well into the O(1) TeV range, assuming that the new resonance decays dominantly to a pair of Standard Model particles. While the SM pair searches are a vital probe of possible new physics, it is important to re-examine the scope of new physics scenarios probed with such final states. Scenarios where new resonances decay dominantly to final states other than SM pairs, even though well theoretically motivated, lie beyond the scope of SM pair searches. In this paper we argue that LHC searches for (vector) resonances beyond two particle final states would be useful complementary probes of new physics scenarios. As an example, we consider a class of composite Higgs models, and identify specific model parameter points where the color singlet, electrically neutral vector resonance ρ0 decays dominantly not to a pair of SM particles, but to a fermionic top partner T f1 and a top quark, with T f1 → tZ. We show that dominant decays of ρ 0 → T f1 t in the context of Composite Higgs models are possible even when the decay channel to a pair of T f1 is kinematically open. Our analysis deals with scenarios where both m ρ and {m}_T{{}{_f}}{_1} are of O(1) TeV, leading to highly boosted t\\overline{t}Z final state topologies. We show that the particular composite Higgs scenario we consider is discoverable at the LHC13 with as little as 30 fb-1, while being allowed by other existing experimental constraints.

The paper describes the use of expert's knowledge in practice and the efficiency of a recently developed technique called argument-based machine learning (ABML) in the knowledge elicitation process. We are developing a neurological decision support system to help the neurologists differentiate between three types of tremors: Parkinsonian, essential, and mixed tremor (comorbidity). The system is intended to act as a second opinion for the neurologists, and most importantly to help them reduce the number of patients in the "gray area" that require a very costly further examination (DaTSCAN). We strive to elicit comprehensible and medically meaningful knowledge in such a way that it does not come at the cost of diagnostic accuracy. To alleviate the difficult problem of knowledge elicitation from data and domain experts, we used ABML. ABML guides the expert to explain critical special cases which cannot be handled automatically by machine learning. This very efficiently reduces the expert's workload, and combines expert's knowledge with learning data. 122 patients were enrolled into the study. The classification accuracy of the final model was 91%. Equally important, the initial and the final models were also evaluated for their comprehensibility by the neurologists. All 13 rules of the final model were deemed as appropriate to be able to support its decisions with good explanations. The paper demonstrates ABML's advantage in combining machine learning and expert knowledge. The accuracy of the system is very high with respect to the current state-of-the-art in clinical practice, and the system's knowledge base is assessed to be very consistent from a medical point of view. This opens up the possibility to use the system also as a teaching tool. Copyright © 2012 Elsevier B.V. All rights reserved.

Assessment, which entails the systematic evaluation of student learning, is an integral part of any educational process. Computer-based assessment (CBA) techniques provide a valuable resource to students seeking to evaluate their academic progress through instantaneous, personalized feedback. CBA reduces examination, grading and reviewing workloads and facilitates training. This paper describes a six step approach for developing CBA in higher education and evaluates student perceptions of computer-based summative assessment at the College of Medicine, King Abdulaziz University. A set of questionnaires were distributed to 341 third year medical students (161 female and 180 male) immediately after examinations in order to assess the adequacy of the system for the exam program. The respondents expressed high satisfaction with the first Saudi experience of CBA for final examinations. However, about 50% of them preferred the use of a pilot CBA before its formal application; hence, many did not recommend its use for future examinations. Both male and female respondents reported that the range of advantages offered by CBA outweighed any disadvantages. Further studies are required to monitor the extended employment of CBA technology for larger classes and for a variety of subjects at universities.

Ceramography was performed on cross sections from four tristructural isotropic (TRISO) coated particle fuel compacts taken from the AGR-2 experiment, which was irradiated between June 2010 and October 2013 in the Advanced Test Reactor (ATR). The fuel compacts examined in this study contained TRISO-coated particles with either uranium oxide (UO2) kernels or uranium oxide/uranium carbide (UCO) kernels that were irradiated to final burnup values between 9.0 and 11.1% FIMA. These examinations are intended to explore kernel and coating morphology evolution during irradiation. This includes kernel porosity, swelling, and migration, and irradiation-induced coating fracture and separation. Variations in behavior within amore » specific cross section, which could be related to temperature or burnup gradients within the fuel compact, are also explored. The criteria for categorizing post-irradiation particle morphologies developed for AGR-1 ceramographic exams, was applied to the particles in the AGR-2 compacts particles examined. Results are compared with similar investigations performed as part of the earlier AGR-1 irradiation experiment. This paper presents the results of the AGR-2 examinations and discusses the key implications for fuel irradiation performance.« less

In this paper, we examine the issue of strategic industrial location selection in uncertain decision making environments for implanting new industrial corporation. In fact, the industrial location issue is typically considered as a crucial factor in business research field which is related to many calculations about natural resources, distributors, suppliers, customers, and most other things. Based on the integration of environmental, economic and social decisive elements of sustainable development, this paper presents a hybrid decision making model combining fuzzy multi-criteria analysis with analytical capabilities that OLAP systems can provide for successful and optimal industrial location selection. The proposed model mainly consists in three stages. In the first stage, a decision-making committee has been established to identify the evaluation criteria impacting the location selection process. In the second stage, we develop fuzzy AHP software based on the extent analysis method to assign the importance weights to the selected criteria, which allows us to model the linguistic vagueness, ambiguity, and incomplete knowledge. In the last stage, OLAP analysis integrated with multi-criteria analysis employs these weighted criteria as inputs to evaluate, rank and select the strategic industrial location for implanting new business corporation in the region of Casablanca, Morocco. Finally, a sensitivity analysis is performed to evaluate the impact of criteria weights and the preferences given by decision makers on the final rankings of strategic industrial locations.

This paper is the third and final of a series that has previously presented the rationale (Rier and Indyk, this volume) and major program elements (Indyk and Rier, this volume) of an approach to link community and tertiary sociomedical providers, clients/patients, sites, and systems into an integrated response to HIV/AIDS. The primary goal has been to improve sociomedical HIV/AIDS services for a hard-to-reach inner city population. The current paper first summarizes the main advantages (e.g., greater efficiency; more realistic, effective programs with greater credibility among the community; stimulation of knowledge production and dissemination amongst players rarely formally engaged in such activities; creation of a platform useful for other applications) of this work. It then examines some of the main organizational challenges in conducting the work (involving issues such as personnel, coordination, funding, turf conflicts, sustainability). From this discussion emerge organizational requisites to conducting this work (e.g., development of key boundary-spanning figures; attention to the specific interests of potential linkage partners; translation efforts to demonstrate the value of participation; a continuous quality improvement approach featuring wide distribution of feedback in user-friendly form; flexibility, tact and patience), so that others can adapt and apply the linkage approach to manage HIV/AIDS or other problems. Finally, we explain how theory and practice have driven one another in this work.

Nowadays, there is a strong demand for inspection systems integrating both high sensitivity under various testing conditions and advanced processing allowing automatic identification of the examined object state and detection of threats. This paper presents the possibility of utilization of a magnetic multi-sensor matrix transducer for characterization of defected areas in steel elements and a deep learning based algorithm for integration of data and final identification of the object state. The transducer allows sensing of a magnetic vector in a single location in different directions. Thus, it enables detecting and characterizing any material changes that affect magnetic properties regardless of their orientation in reference to the scanning direction. To assess the general application capability of the system, steel elements with rectangular-shaped artificial defects were used. First, a database was constructed considering numerical and measurements results. A finite element method was used to run a simulation process and provide transducer signal patterns for different defect arrangements. Next, the algorithm integrating responses of the transducer collected in a single position was applied, and a convolutional neural network was used for implementation of the material state evaluation model. Then, validation of the obtained model was carried out. In this paper, the procedure for updating the evaluated local state, referring to the neighboring area results, is presented. Finally, the results and future perspective are discussed. PMID:29351215

The use of genetic information in the insurance sector--a German perspective.
Armbrüster, Christian; Obal, Monika
2013-01-01
The following paper offers an introduction to the legal framework concerning the use of genetic information in the insurance sector in Germany. The main contents and the controversial issues of the key regulation are examined. The aim of this rule being to secure human dignity by respecting the right to informational self-determination regarding genetic data, including the individual's right not to know about their genetic characteristics, there are a number of open issues which are being addressed. For instance, the influence of the prohibition to ask for genetic testing and to use the results of any such testing by the insurer is examined. This examination leads to some explicit results, such as the assumption that in addition to the ban on the use of genetic testing no questions about family medical history are admissible. The authors embark on the definition of genetic testing and the question to what extent the results of diagnostic genetic testing may still be made use of in the context of the insured person's obligation to display pre-existing conditions and diseases when the contract is concluded. In this respect distinctions between diagnostic and predictive genetic testing as well as between disease and disposition are drawn. Furthermore, the exceptions from the prohibition to use results of genetic testing are examined, and the scope of the prohibition of acceptance of results of genetic testing even if performed at the instigation of the insured is explored. Finally the consequences, encompassing criminal liability and private law ramifications, of the violation of the prohibition are presented. In this context, a narrow understanding of the aggravated criminal offence of using results of genetic testing with the intent to personal enrichment or in return for payments is developed. Finally the effects on the validity of the insurance contract and the question whether the insurer may be forced to conclude a contract are examined.

Financing long-term care: ex ante, ex post or both?
Costa-Font, Joan; Courbage, Christophe; Swartz, Katherine
2015-03-01
This paper attempts to examine the heterogeneity in the public financing of long-term care (LTC) and the wide-ranging instruments in place to finance LTC services. We distinguish and classify the institutional responses to the need for LTC financing as ex ante (occurring prior to when the need arises, such as insurance) and ex post (occurring after the need arises, such as public sector and family financing). Then, we examine country-specific data to ascertain whether the two types of financing are complements or substitutes. Finally, we examine exploratory cross-national data on public expenditure determinants, specifically economic, demographic and social determinants. We show that although both ex ante and ex post mechanisms exist in all countries with advanced industrial economies and despite the fact that instruments are different across countries, ex ante and ex post instruments are largely substitutes for each other. Expenditure estimates to date indicate that the public financing of LTC is highly sensitive to a country's income, ageing of the population and the availability of informal caregiving.

Network Centrality of Metro Systems
Derrible, Sybil
2012-01-01
Whilst being hailed as the remedy to the world’s ills, cities will need to adapt in the 21st century. In particular, the role of public transport is likely to increase significantly, and new methods and technics to better plan transit systems are in dire need. This paper examines one fundamental aspect of transit: network centrality. By applying the notion of betweenness centrality to 28 worldwide metro systems, the main goal of this paper is to study the emergence of global trends in the evolution of centrality with network size and examine several individual systems in more detail. Betweenness was notably found to consistently become more evenly distributed with size (i.e. no “winner takes all”) unlike other complex network properties. Two distinct regimes were also observed that are representative of their structure. Moreover, the share of betweenness was found to decrease in a power law with size (with exponent 1 for the average node), but the share of most central nodes decreases much slower than least central nodes (0.87 vs. 2.48). Finally the betweenness of individual stations in several systems were examined, which can be useful to locate stations where passengers can be redistributed to relieve pressure from overcrowded stations. Overall, this study offers significant insights that can help planners in their task to design the systems of tomorrow, and similar undertakings can easily be imagined to other urban infrastructure systems (e.g., electricity grid, water/wastewater system, etc.) to develop more sustainable cities.

Saludes, Ronaldo B; Iwabuchi, Kazunori; Miyatake, Fumihito; Abe, Yoshiyuki; Honda, Yoshifumi
2008-10-01
The aim of this research was to evaluate the use of manufacturing wallboard paper scraps as an alternative bulking agent for dairy cattle manure composting. The characteristics of the composting process were studied based on the changes in physico-chemical parameters and final compost quality. Composting of dairy cattle manure with wallboard paper was performed in a 481-L cylindrical reactor with vacuum-type aeration. Rapid degradation of organic matter was observed during the thermophilic stage of composting due to high microbial activity. High temperature and alkaline pH conditions promoted intense ammonia emission during the early stage of composting. The number of mesophilic and thermophilic microorganisms were found to be affected by changes in temperature at different composting stages. The total nitrogen (N), phosphorus (P), potassium (K), and sodium (Na) concentrations of the mixture did not change significantly after 28days of composting. However, the presence of gypsum in the paper scraps increased the calcium content of the final compost. The wallboard paper had no phyto-inhibitory effects as shown by high germination index of final compost (GI=99%).
Nursing workforce planning: insights from seven Malaysian hospitals.
Drake, Robert
In 2010, the Royal College of Nursing asked: 'What is the optimal level and mix of nurses required to deliver quality care as cost-effectively as possible?' This question implies there is a relationship between staffing levels, quality of care and financial efficiency. This paper examines the relationship between the staff budget, the number of staff required to achieve a target level of care and the actual number of staff employed in seven hospitals in Malaysia. It seeks to critically evaluate local challenges arising from staff budgeting/planning procedures, identify general issues that apply beyond Malaysian healthcare institutions and, finally, to propose a model that combines finance, staffing and level of care.
Feminism and public health ethics
Rogers, W A
2006-01-01
This paper sketches an account of public health ethics drawing upon established scholarship in feminist ethics. Health inequities are one of the central problems in public health ethics; a feminist approach leads us to examine not only the connections between gender, disadvantage, and health, but also the distribution of power in the processes of public health, from policy making through to programme delivery. The complexity of public health demands investigation using multiple perspectives and an attention to detail that is capable of identifying the health issues that are important to women, and investigating ways to address these issues. Finally, a feminist account of public health ethics embraces rather than avoids the inescapable political dimensions of public health. PMID:16731735

In this paper, we review the principal theoretical models through which the dielectric function of metals can be described. Starting from the Drude assumptions for intraband transitions, we show how this model can be improved by including interband absorption and temperature effect in the damping coefficients. Electronic scattering processes are described and included in the dielectric function, showing their role in determining plasmon lifetime at resonance. Relationships among permittivity, electric conductivity and refractive index are examined. Finally, a temperature dependent permittivity model is presented and is employed to predict temperature and non-linear field intensity dependence on commonly used plasmonic geometries, such as nanospheres.

This paper will briefly review previous work in wind tunnel Magnetic Suspension and Balance Systems (MSBS) and will examine the handful of systems around the world currently known to be in operational condition or undergoing recommissioning. Technical developments emerging from research programs at NASA and elsewhere will be reviewed briefly, where there is potential impact on large-scale MSBSS. The likely aerodynamic applications for large MSBSs will be addressed, since these applications should properly drive system designs. A recently proposed application to ultra-high Reynolds number testing will then be addressed in some detail. Finally, some opinions on the technical feasibility and usefulness of a large MSBS will be given.
Exploring Dance Movement Data Using Sequence Alignment Methods

2015-01-01
Despite the abundance of research on knowledge discovery from moving object databases, only a limited number of studies have examined the interaction between moving point objects in space over time. This paper describes a novel approach for measuring similarity in the interaction between moving objects. The proposed approach consists of three steps. First, we transform movement data into sequences of successive qualitative relations based on the Qualitative Trajectory Calculus (QTC). Second, sequence alignment methods are applied to measure the similarity between movement sequences. Finally, movement sequences are grouped based on similarity by means of an agglomerative hierarchical clustering method. The applicability of this approach is tested using movement data from samba and tango dancers. PMID:26181435

In this paper, we discuss dust motion and investigate possible mass transfer of charged particles in a binary asteroid system, in which the asteroids are electrically charged due to solar radiation. The surface potential of the asteroids is assumed to be a piecewise function, with positive potential on the sunlit half and negative potential on the shadow half. We derive the nonautonomous equations of motion for charged particles and an analytic representation for their lofting conditions. Particle trajectories and temporary relative equilibria are examined in relation to their moving forbidden regions, a concept we define and discuss. Finally, we use a Monte Carlo simulation for a case study on mass transfer and loss rates between the asteroids.
The Role of Sleep in Childhood Psychiatric Disorders
Alfano, Candice A.; Gamble, Amanda L.
2009-01-01
Although sleep problems often comprise core features of psychiatric disorders, inadequate attention has been paid to the complex, reciprocal relationships involved in the early regulation of sleep, emotion, and behavior. In this paper, we review the pediatric literature examining sleep in children with primary psychiatric disorders as well as evidence for the role of early sleep problems as a risk factor for the development of psychopathology. Based on these cumulative data, possible mechanisms and implications of early sleep disruption are considered. Finally, assessment recommendations for mental health clinicians working with children and adolescents are provided toward reducing the risk of and improving treatments for sleep disorders and psychopathology in children and adolescents.

This paper examines statistical issues associated with estimating paths of juvenile salmon through the intakes of Kaplan turbines. Passive sensors, hydrophones, detecting signals from ultrasonic transmitters implanted in individual fish released into the preturbine region were used to obtain the information to estimate fish paths through the intake. Aim and location of the sensors affects the spatial region in which the transmitters can be detected, and formulas relating this region to sensor aiming directions are derived. Cramer-Rao lower bounds for the variance of estimators of fish location are used to optimize placement of each sensor. Finally, a statistical methodology is developed for analyzing angular data collected from optimally placed sensors.
Kepler's relation to the Jesuits-A study of his correspondence with Paul Guldin.
Schuppener, Georg
1997-12-01
First, this article provides a survey of the kind of relationship that existed between Kepler and the Jesuits. Afterwards, it is pondered upon the likelihood of their having been in direct contact with each other while Kepler lived in Prague. The second part of the article is devoted to an investigation into the correspondence between Kepler and Paul Guldin as an example. Thus, the paper describes the key issues of those letters and concludes from this Guldin's attitude to Kepler and the resulting commitment to Kepler's affairs. Finally, the article examines whether the assumption that Kepler and Guldin later discontinued their correspondence intensionally is verifiable and plausible.
Gamete donation in France: the future of the anonymity doctrine.
Brunet, Laurence; Kunstmann, Jean-Marie
2013-02-01
In France, since the approval of the first bioethics laws in 1994, the principle of the anonymity of sperm donors has prevailed. This choice is regularly challenged, namely by children who have been conceived under these conditions and have now reached adulthood. In this paper, we will briefly describe the reasons that led practitioners of assisted reproduction to endorse the anonymity principle in 1994. Secondly, we will elaborate on the reasons why this principle is becoming so controversial today. Finally, we shall examine two possible outcomes of the debate, highlighting their respective legitimacy as well as their consequences, as far as the rights of children, the notion of the family, and medical practice are concerned.
Supporting multi-stakeholder environmental decisions.
Hajkowicz, Stefan A
2008-09-01
This paper examines how multiple criteria analysis (MCA) can be used to support multi-stakeholder environmental management decisions. It presents a study through which 48 stakeholders from environmental, primary production and community interest groups used MCA to prioritise 30 environmental management problems in the Mackay-Whitsunday region of Queensland, Australia. The MCA model, with procedures for aggregating multi-stakeholder output, was used to inform a final decision on the priority of the region's environmental management problems. The result was used in the region's environmental management plan as required under Australia's Natural Heritage Trust programme. The study shows how relatively simple MCA methods can help stakeholders make group decisions, even when they hold strongly conflicting preferences.

Previous work revealed that α-tocopherol transfer protein (α-TTP) co-localizes with bis(monoacylglycero)phosphate (BMP) in late endosomes. BMP is a lipid unique to late endosomes and is believed to induce membrane curvature and support the multivesicular nature of this organelle. In this paper, we examined the effect of BMP on α-TTP binding to membranes using dual polarization interferometry and vesicle-binding assay. α-TTP binding to membranes is increased by the curvature-inducing lipid BMP. Finally, α-TTP binds to membranes with greater affinity when they contain the 2,2'-BMP versus 3,1'-BMP isomers.
Physical studies of the planetary rings

Ip, W.-H.
1980-01-01
In this review paper, the physical properties of the Saturnian and Uranian rings as derived from ground-based observations are first discussed. Focus is then shifted to the study of the orbital dynamics of the ring particles. Numerical simulations of the evolutionary history of a system of colliding particles in differential rotation together with theoretical modeling of the inelastic collision processes are surveyed. In anticipation of the information returned from in situ measurements by space probes, interactions of the planetary rings with the interplanetary meteoroids and planetary magnetospheres are briefly considered. Finally, models of planetary ring origin are examined. In this connection, some recent work on the satellite resonant perturbation effects on the ring structure are also touched upon.

This paper examines the initial data for the evolution of the space-time solution of Einstein's equations admitting a conformal symmetry. Under certain conditions on the extrinsic curvature of the initial complete spacelike hypersurface and sectional curvature of the space-time with respect to sections containing the normal vector field, we have shown that the initial hypersurface is conformally diffeomorphic to a sphere or a flat space or a hyperbolic space or the product of an open real interval and a complete 2-manifold. It has been further shown that if the initial hypersurface is compact, then it is conformally diffeomorphic to a sphere. Finally, the conformal symmetries of a generalized Robertson-Walker space-time have been described.

Ultrafast optical microscopy is an important tool for examining fundamental phenomena in semiconductor nanowires with high temporal and spatial resolution. In this paper, we used this technique to study carrier dynamics in single GaN/InGaN core–shell nonpolar multiple quantum well nanowires. We find that intraband carrier–carrier scattering is the main channel governing carrier capture, while subsequent carrier relaxation is dominated by three-carrier Auger recombination at higher densities and bimolecular recombination at lower densities. Finally, the Auger constants in these nanowires are approximately 2 orders of magnitude lower than in planar InGaN multiple quantum wells, highlighting their potential for future light-emitting devices.
Flight trajectories with maximum tangential thrust in a central Newtonian field

Azizov, A. G.; Korshunova, N. A.
1983-07-01
The paper examines the two-dimensional problem of determining the optimal trajectories of a point moving with a limited per-second mass consumption in a central Newtonian field. It is shown that one of the cases in which the variational equations in the Meier formulation can be integrated in quadratures is motion with maximum tangential thrust. Trajectories corresponding to this motion are determined. By way of application, attention is given to the problem of determining the thrust which assures maximum kinetic energy for the point at the moment t = t1, corresponding to the mass consumption M0 - M1, where M0 and M1 are, respectively, the initial and final mass.
Tomographic phase microscopy: principles and applications in bioimaging [Invited

2017-01-01
Tomographic phase microscopy (TPM) is an emerging optical microscopic technique for bioimaging. TPM uses digital holographic measurements of complex scattered fields to reconstruct three-dimensional refractive index (RI) maps of cells with diffraction-limited resolution by solving inverse scattering problems. In this paper, we review the developments of TPM from the fundamental physics to its applications in bioimaging. We first provide a comprehensive description of the tomographic reconstruction physical models used in TPM. The RI map reconstruction algorithms and various regularization methods are discussed. Selected TPM applications for cellular imaging, particularly in hematology, are reviewed. Finally, we examine the limitations of current TPM systems, propose future solutions, and envision promising directions in biomedical research. PMID:29386746

Several adolescent developmental problems in Hong Kong are briefly reviewed in this paper. First, rising adolescent substance abuse trends are described. Second, Internet use problems and Internet addiction among young people are examined. Third, worrying trends in adolescent sexuality are identified. Fourth, phenomena on bullying among young people are reviewed. Finally, phenomena related to adolescent materialistic orientation are focused upon. With reference to these adolescent developmental problems, possible solutions are briefly discussed particularly with reference to the ecological perspective. It is argued that the related scientific literature provides useful pointers for designing the curriculum in the extension phase of the Project P.A.T.H.S. in Hong Kong. PMID:22194661

I will explore the similarities and differences between the process of writing science fiction and the process of 'producing' science, specifically theoretical physics. What are the ground rules for introducing unproven new ideas in science fiction, and how do they differ from the corresponding rules in physics? How predictive is science fiction? (For that matter, how predictive is theoretical physics?) I will also contrast the way in which information is presented in science fiction, as opposed to its presentation in scientific papers, and I will examine the relative importance of ideas (as opposed to the importance of the way in which these ideas are presented). Finally, I will discuss whether a background as a research scientist provides any advantage in writing science fiction.
A process for providing positive primary control power by wind turbines
NASA Astrophysics Data System (ADS)
Marschner, V.; Michael, J.; Liersch, J.
2014-12-01
Due to the increasing share of wind energy in electricity generation, wind turbines have to fulfil additional requirements in the context of grid integration. The paper examines to which extent wind turbines can provide positive control power following the related grid code. The additional power has to be obtained from the rotating flywheel mass of the wind turbine's rotor. A simple physical model is developed that allows to draw conclusions about appropriate concepts by means of a dynamic simulation of the variables rotational speed, torque, power output and rotor power. The paper discusses scenarios to provide control power. The supply of control power at partial load is examined in detail using simulations. Under partial load conditions control power can be fed into the grid for a short time. Thereby the rotational speed drops so that aerodynamic efficiency decreases and feed-in power is below the initial value after the control process. In this way an unfavourable situation for the grid control is produced, therefore the paper proposes a modified partial load condition with a higher rotational speed. By providing primary control power the rotor is delayed to the optimum rotational speed so that more rotational energy can be fed in and fed-in power can be increased persistently. However, as the rotor does not operate at optimum speed, a small amount of the energy yield is lost. Finally, the paper shows that a wind farm can combine these two concepts: A part of the wind turbines work under modified partial load conditions can compensate the decrease of power of the wind turbines working under partial load conditions. Therefore the requested control power is provided and afterwards the original value of power is maintained.
Upscaling: Effective Medium Theory, Numerical Methods and the Fractal Dream
NASA Astrophysics Data System (ADS)
Guéguen, Y.; Ravalec, M. Le; Ricard, L.
2006-06-01
Upscaling is a major issue regarding mechanical and transport properties of rocks. This paper examines three issues relative to upscaling. The first one is a brief overview of Effective Medium Theory (EMT), which is a key tool to predict average rock properties at a macroscopic scale in the case of a statistically homogeneous medium. EMT is of particular interest in the calculation of elastic properties. As discussed in this paper, EMT can thus provide a possible way to perform upscaling, although it is by no means the only one, and in particular it is irrelevant if the medium does not adhere to statistical homogeneity. This last circumstance is examined in part two of the paper. We focus on the example of constructing a hydrocarbon reservoir model. Such a construction is a required step in the process of making reasonable predictions for oil production. Taking into account rock permeability, lithological units and various structural discontinuities at different scales is part of this construction. The result is that stochastic reservoir models are built that rely on various numerical upscaling methods. These methods are reviewed. They provide techniques which make it possible to deal with upscaling on a general basis. Finally, a last case in which upscaling is trivial is considered in the third part of the paper. This is the fractal case. Fractal models have become popular precisely because they are free of the assumption of statistical homogeneity and yet do not involve numerical methods. It is suggested that using a physical criterion as a means to discriminate whether fractality is a dream or reality would be more satisfactory than relying on a limited data set alone.

From a naturalistic perspective on mental illness, depression is often described in terms of biological dysfunctions, while a normative perspective emphasizes the lived experience of depression as a harmful condition. The paper relates a conceptual analysis of “depressive situation” to an analysis of the lived experience of depression. As such, it predominantly aims to specify depression as a harmful condition in lights of normative perspective on mental disorder, but partially refers to empirical research, i.e., naturalistic perspective on depression, to exemplarily stress on the methodological merits and limits of relating phenomenological considerations closer to empirical research. The depressive situation is further specified with an examination of the evaluative dynamics by which individuals meaningfully relate to themselves, others and the world. These evaluative dynamics emerge out of the interplay of pre-reflective and reflective processes, which are significantly altered in depression. Such alterations of the evaluative structure are inextricably intertwined with significant distortions of practical sense in depression. From a phenomenological perspective, these distortions of practical sense show in characteristic experiences of evaluative incoherence and impairments of agency. Finally, this paper focuses on an examination of “evaluative incapacity,” which has the integrative potential to capture a range of typical changes of meaningful relatedness that determine the depressive situation.

Markets are often considered superior to other global scheduling mechanisms for distributed computing systems. This claim is supported by: a casual observation from our every-day life that markets successfully equilibrate supply and demand, and the features of markets which originate in the general equilibrium theory, e.g., efficiency and the lack of necessity of 2 central controller. This paper describes why such beliefs in markets are not warranted. It does so by examining the general equilibrium theory, in terms of scope, abstraction, and interpretation. Not only does the general equilibrium theory fail to provide a satisfactory explanation of actual economies, including a computing-resource economy, it also falls short of supplying theoretical foundations for commonly held views of market desirability. This paper also points out that the argument for the desirability of markets involves circular reasoning and that the desirability can be established only vis-a-vis a scheduling goal. Finally, recasting the conclusion of Arrow's Impossibility Theorem as that for global scheduling, we conclude that there exists no market-based scheduler that is rational (in the sense defined in microeconomic theory), takes into account utility of more than one user, and yet yields a Pareto-optimal outcome for arbitrary user utility functions.

Historians of science have long been agreeing: what many textbooks of evolutionary biology say, about the histories of Darwinism and the New Synthesis, is just too simple to do justice to the complexities revealed to critical scholarship and historiography. There is no current consensus, however, on what grand narratives should replace those textbook histories. The present paper does not offer to contribute directly to any grand, consensual, narrational goals; but it does seek to do so indirectly by showing how, in just one individual case, details of intellectual biography connect with big picture issues. To this end, I examine here how very diverse scientific and metaphysical commitments were integrated in Sewall Wright's own personal synthesis of biology and philosophy. Taking as the decisive text the short final section of Wright's long 1931 paper on 'Evolution in Mendelian populations,' I examine how his shifting balance theory (SBT) related to his optimum breeding strategy research, his physiological genetics, his general theory of homogenising and heterogenesing causation and his panpsychist view of mind and matter; and I discuss how understanding these relations can clarify Wright's place in the longue durée of evolutionary thought.

Race, racism and health: disparities, mechanisms, and interventions.
Brondolo, Elizabeth; Gallo, Linda C; Myers, Hector F
2009-02-01
The goals of this special section are to examine the state-of-the-science regarding race/ethnicity and racism as they contribute to health disparities and to articulate a research agenda to guide future research. In the first paper, Myers presents an integrative theoretical framework for understanding how racism, poverty, and other major stressors relate to health through inter-related psychosocial and bio-behavioral pathways. Williams and Mohammed review the evidence concerning associations between racism and health, addressing the multiple levels at which racism can operate and commenting on important methodological issues. Klonoff provides a review and update of the literature concerning ethnicity-related disparities in healthcare, and addresses factors that may contribute to these disparities. Brondolo and colleagues consider racism from a stress and coping perspective, and review the literature concerning racial identity, anger coping, and social support as potential moderators of the racism-health association. Finally, Castro and colleagues describe an ecodevelopmental model that can serve as an integrative framework to examine multi-level social-cultural influences on health and health behavior. In aggregate, the special section papers address theoretical and methodological issues central to understanding the determinants of health disparities, with the aim of providing direction for future research critical to developing effective interventions to reduce these disparities.
Backs to the future? Reflections on women, ageing and nursing.
Bernard, M
1998-03-01
There is now a certain amount of evidence to support the contention that ageism is not only rife amongst the population at large, but also amongst many of those who care for older people in a professional capacity. Given that many of these professionals are women caring for other women -- and nursing is a prime example -- this should at the very least give us serious cause for concern. This paper explores the relationship between 'ageing women' and 'old women' from the point of view of personal and professional attitudes and practices. It examines the proposition that until we, as women, fully explore and understand our own attitudes towards ageing and old age, we cannot work in ways which are truly beneficial and empowering for the older women in our care. The purpose of the paper is threefold. First, it reviews what is a relatively limited body of literature and research on this topic. Second, it reports on the preliminary findings from an exploratory study examining the attitudes of female nurses to their own ageing. Finally, it reflects further on the issues raised and considers some of the ways in which we can begin to address and confront the challenges which being 'ageing women' and 'aged women' in late 20th century Britain presents.
Globalisation, transnational policies and adult education

Globalisation, transnational policies and adult education - This paper examines policy documents produced by the United Nations Educational, Scientific and Cultural Organization (UNESCO) and the European Union (EU) in the field of adult education and learning. Both these entities address adult education as an explicit object of policy. This paper investigates how globalisation processes are constructed as policy problems when these transnational political agents propose adult education as a response. The author's main argument is that while UNESCO presents the provision of adult education as a means for governments worldwide to overcome disadvantages experienced by their own citizenry, the EU institutionalises learning experiences as a means for governments to sustain regional economic growth and political expansion. After reviewing the literature on globalisation to elucidate the theories that inform current understanding of contemporary economic, political, cultural and ecological changes as political problems, she presents the conceptual and methodological framework of her analysis. The author then examines the active role played by UNESCO and the EU in promoting adult education as a policy objective at transnational level, and unpacks the specific problem "representations" that are substantiated by these organisations. She argues that UNESCO and EU processes assign specific values and meanings to globalisation, and that these reflect a limited understanding of the complexity of globalisation. Finally, she considers two of the effects produced by these problem representations.

The purpose of this paper is to describe unique culturally-based factors that may increase the vulnerability of Asian American adolescents to engage in alcohol use and abuse and the role of parent-child bonding as a protective factor. In particular, this paper addresses the interactions among acculturation, alcohol use, and parent-child bonding and the challenges Asian American families face in strengthening parent-child bonds. We begin by examining likely causes for alienation that occur as a result of immigration to the United States. We then present the cultural context of Asian American families that can also serve to create distance between parent and child, including the contrasting cultural orientations of individualism and collectivism, Asian traditional values, differences in Eastern and Western parenting styles, and intergenerational cultural dissonance. Next, we present a review of the research that has examined acculturation as a risk factor for alcohol use and abuse among Asian American adolescents, with special attention to the mediating role of parent-child bonding. Finally, we conclude with recommendations for future research on the risk and protective factors for adolescent substance abuse, as well as other risky health behaviors among the growing population of Asian Americans in the United States.

Influence of non-homogeneous mixing on final epidemic size in a meta-population model.
Cui, Jingan; Zhang, Yanan; Feng, Zhilan
2018-06-18
In meta-population models for infectious diseases, the basic reproduction number [Formula: see text] can be as much as 70% larger in the case of preferential mixing than that in homogeneous mixing [J.W. Glasser, Z. Feng, S.B. Omer, P.J. Smith, and L.E. Rodewald, The effect of heterogeneity in uptake of the measles, mumps, and rubella vaccine on the potential for outbreaks of measles: A modelling study, Lancet ID 16 (2016), pp. 599-605. doi: 10.1016/S1473-3099(16)00004-9 ]. This suggests that realistic mixing can be an important factor to consider in order for the models to provide a reliable assessment of intervention strategies. The influence of mixing is more significant when the population is highly heterogeneous. In this paper, another quantity, the final epidemic size ([Formula: see text]) of an outbreak, is considered to examine the influence of mixing and population heterogeneity. Final size relation is derived for a meta-population model accounting for a general mixing. The results show that [Formula: see text] can be influenced by the pattern of mixing in a significant way. Another interesting finding is that, heterogeneity in various sub-population characteristics may have the opposite effect on [Formula: see text] and [Formula: see text].

At Texas A&M University, introductory-level surgical lecture and laboratory notes were converted to a CD-ROM format that included illustrative photographs as well as instructional videos demonstrating the basic surgical skills that all students were required to master. The CD-ROM was distributed to all students in place of traditional paper notes in the second-year surgical class in the professional veterinary curriculum. The study reported here was designed to evaluate the educational benefits of the use of the CD-ROM in place of traditional paper notes by examining the attitudes and practices of students before and after exposure to the CD-ROM format. An anonymous survey was distributed to students in the second-year introductory surgery course on the first day of class and again on the last day of class. Responses to questions were tabulated, response frequencies determined, and Chi-square analysis performed to determine differences between initial and final responses. On the final survey, 89 per cent of students responded that the instructional videos definitely helped them prepare for the laboratory, and 77 per cent responded that they were more likely to practice techniques learned from the CD-ROM videos than those learned from traditional study materials. The majority of students believed that the CD-ROM improved both the course (60 per cent) and their learning experience (62 per cent) as compared to traditional paper notes. Including instructional videos on the CD-ROM enhanced the educational experience of the students by promoting preparedness for laboratories and promoting practice of techniques learned from the videos outside of the laboratory.

This paper presents empirical results of cable noise reduction techniques as demonstrated in a TEM cell operating with radiated fields from 2 - 200 MHz. It is the second part of a two-paper series. The first paper discussed cable types and shield connections. In this second paper, the effects of load and source resistances and chassis connections are examined. For each topic, well established theories are compared to data from a real-world physical system. Finally, recommendations for minimizing cable susceptibility (and thus cable emissions) are presented. There are numerous papers and textbooks that present theoretical analyses of cable noise reduction techniques. However, empirical data is often targeted to low frequencies (e.g. <50 KHz) or high frequencies (>100 MHz). Additionally, a comprehensive study showing the relative effects of various noise reduction techniques is needed. These include the use of dedicated return wires, twisted wiring, cable shielding, shield connections, changing load or source impedances, and implementing load- or source-to-chassis isolation. We have created an experimental setup that emulates a real-world electrical system, while still allowing us to independently vary a host of parameters. The goal of the experiment was to determine the relative effectiveness of various noise reduction techniques when the cable is in the presence of radiated emissions from 2 MHz to 200 MHz.

This paper provides insights into the way gendered assumptions operate within health care interventions for women with eating disorders. A multidisciplinary sample of Australian health care workers were interviewed about their approaches to treatment, and discourse analysis was used to uncover the discursive dynamics and power relations characterising their accounts of intervention. The paper demonstrates a contradictory positioning of anorexic patients in relation to autonomy and control within the two common psychiatric interventions of bed rest intervention and psychotherapy. The paper argues that this is based on gendered assumptions about selfhood and femininity in eating disorders that are reproduced in the therapeutic relationship through the operation of a gendered parent-child dynamic, with the health care worker as father or mother, and the anorexic patient as daughter. One of the main effects of this is to re-inscribe rather than challenge the discursive 'double bind' of femininity that has been widely implicated by post-structural feminists in producing eating disorders in the first place. The paper also considers the widely acknowledged problem of resistance to treatment in anorexia as a function of controlling treatments, and discusses psychiatrists' perspectives on addressing this dilemma. Finally, the paper examines the potential of feminist-informed understandings of eating disorders for overcoming the gendered dilemmas inherent within the dominant psycho-medical treatment paradigm.

New frontiers for intelligent content-based retrieval
NASA Astrophysics Data System (ADS)
Benitez, Ana B.; Smith, John R.
2001-01-01
In this paper, we examine emerging frontiers in the evolution of content-based retrieval systems that rely on an intelligent infrastructure. Here, we refer to intelligence as the capabilities of the systems to build and maintain situational or world models, utilize dynamic knowledge representation, exploit context, and leverage advanced reasoning and learning capabilities. We argue that these elements are essential to producing effective systems for retrieving audio-visual content at semantic levels matching those of human perception and cognition. In this paper, we review relevant research on the understanding of human intelligence and construction of intelligent system in the fields of cognitive psychology, artificial intelligence, semiotics, and computer vision. We also discus how some of the principal ideas form these fields lead to new opportunities and capabilities for content-based retrieval systems. Finally, we describe some of our efforts in these directions. In particular, we present MediaNet, a multimedia knowledge presentation framework, and some MPEG-7 description tools that facilitate and enable intelligent content-based retrieval.

The Collaborative Modeling for Parametric Assessment of Space Systems (COMPASS) team at Glenn Research Center has performed integrated system analysis of conceptual spacecraft mission designs since 2006 using a multidisciplinary concurrent engineering process. The set of completed designs was archived in a database, to allow for the study of relationships between design parameters. Although COMPASS uses a parametric spacecraft costing model, this research investigated the possibility of using a top-down approach to rapidly estimate the overall vehicle costs. This paper presents the relationships between significant design variables, including breakdowns of dry mass, wet mass, and cost. It also develops a model for a broad estimate of these parameters through basic mission characteristics, including the target location distance, the payload mass, the duration, the delta-v requirement, and the type of mission, propulsion, and electrical power. Finally, this paper examines the accuracy of this model in regards to past COMPASS designs, with an assessment of outlying spacecraft, and compares the results to historical data of completed NASA missions.
Chemical hazards associated with treatment of waste electrical and electronic equipment

This review paper summarizes the existing knowledge on the chemical hazards associated with recycling and other end-of-life treatment options of waste electrical and electronic equipment (e-waste). The hazards arise from the presence of heavy metals (e.g., mercury, cadmium, lead, etc.), flame retardants (e.g., pentabromophenol, polybrominated diphenyl ethers (PBDEs), tetrabromobisphenol-A (TBBPA), etc.) and other potentially harmful substances in e-waste. If improperly managed, the substances may pose significant human and environmental health risks. The review describes the potentially hazardous content of e-waste, examines the existing e-waste management practices and presents scientific data on human exposure to chemicals, workplace and environmental pollution associatedmore » with the three major e-waste management options, i.e., recycling, incineration and landfilling. The existing e-waste management practices and associated hazards are reviewed separately for developed and developing countries. Finally, based on this review, the paper identifies gaps in the existing knowledge and makes some recommendations for future research.« less
Unusual Sleep Experiences, Dissociation, and Schizotypy: Evidence for a Common Domain
Koffel, Erin; Watson, David
2009-01-01
This paper reviews studies that have examined associations between unusual sleep experiences (including nightmares, vivid dreaming, narcolepsy symptoms, and complex nighttime behaviors) and dissociation and schizotypy. Using correlational studies and structural analyses, evidence is provided that unusual sleep experiences, dissociation, and schizotypy belong to a common domain. It is demonstrated that unusual sleep experiences show specificity to dissociation and schizotypy compared to other daytime symptoms (e.g., anxiety, depression, substance use) and other sleep disturbances (e.g., insomnia, lassitude/fatigue). The paper also outlines the methodological limitations of the existing evidence and makes suggestions for future research. Finally, three models for the overlap of daytime and nighttime symptoms are reviewed, including biological abnormalities, trauma, and personality traits. Although further research is needed, it is suggested that daytime and nighttime symptoms result from problems with sleep-wake state boundaries, which may be precipitated by stress or trauma. In addition, association between daytime and nighttime symptoms can be attributed to the higher order personality trait of Oddity. PMID:19581031
Evidence-based health care: its place within clinical governance.
McSherry, R; Haddock, J
This article explores the principles of evidence-based practice and its role in achieving quality improvements within the clinical governance framework advocated by the recent White Papers 'The New NHS: Modern, Dependable' (Department of Health (DoH), 1997) and 'A First Class Service: Quality in the New NHS' (DoH, 1998a). Within these White Papers there is an emphasis on improving quality of care, treatment and services through employing the principles of clinical governance. A major feature of clinical governance is guaranteeing quality to the public and the NHS, and ensuring that clinical, managerial and educational practice is based on scientific evidence. This article also examines what evidence-based practice is and what processes are required to promote effective healthcare interventions. The authors also look at how clinical governance relates to other methods/systems involved in clinical effectiveness. Finally, the importance for nurses and other healthcare professionals of familiarizing themselves with the development of critical appraisal skills, and their implications for developing evidence-based practice, is emphasized.
[Cell phones: health risks and prevention].
Talamanca, I Figà; Giliberti, C; Salerno, S
2012-01-01
The paper describes first of all the electromagnetic radiation of cellular phones and presents the physical parameters used to measure and evaluate the absorption of emissions of radio stations and cellular phones. It then presents selected research results of the experimental studies in vivo and in vitro which examine the biological effects of the emissions of cellular phones. The review of the epidemiologic evidence focuses in particular the epidemiologic studies on the use of cell phones and brain tumours, identifying some of the reasons of the conflicting results obtained. Studies dealing with the health risks involved in the increasing use of cellular phones by adolescents and children, more sensitive to this exposure, are also presented showing the need for special caution. The problem of hypersensitivity observed in some individuals is also briefly discussed. Finally the paper presents a summary of the main prevention measures necessary in order to reduce the risks in the framework of the "precautionary principle" including prevention policies and exposure limits in various countries.

The diagnostic algorithm for patients with Graves' disease frequently involves the use of thyroid autoantibody testing and radioisotope scanning (full text available online: http://education.amjmed.com/pp1/248). However, ultrasound has myriad uses in the evaluation of patients with hyperthyroidism. The purpose of this paper is to review the medical literature outlining the important role that ultrasonography (US) can play in the diagnosis and management of patients with hyperthyroidism. We will make a case for the use of ultrasonography in the initial evaluation of all patients with thyrotoxicosis. This review will delineate the advantages of ultrasonography compared to nuclear medicine imaging in determining the etiology of the hyperthyroidism. The role of sonography in predicting remission and relapse of Graves' disease will also be examined. Finally, this paper will detail the importance of ultrasonography in the workup of hyperthyroidism during pregnancy. We will also outline its utility for predicting fetal thyroid dysfunction in maternal Graves' disease without the need for cordocentesis and its attendant complications. Copyright © 2012.

This paper examines the co-ordination strategies developed to respond to the Great Lakes crisis following the events of April 1994. It analyses the different functions and mechanisms which sought to achieve a co-ordinated response--ranging from facilitation at one extreme to management and direction at the other. The different regimes developed to facilitate co-ordination within Rwanda and neighbouring countries, focusing on both inter-agency and inter-country co-ordination issues, are then analysed. Finally, the paper highlights the absence of mechanisms to achieve coherence between the humanitarian, political and security domains. It concludes that effective co-ordination is critical not only to achieve programme efficiency, but to ensure that the appropriate instruments and strategies to respond to complex political emergencies are in place. It proposes a radical re-shaping of international humanitarian, political and security institutions, particularly the United Nations, to improve the effectiveness of humanitarian and political responses to crises such as that in the Great Lakes.
Casuistry as bioethical method: an empirical perspective.
Braunack-Mayer, A
2001-07-01
This paper examines the role that casuistry, a model of bioethical reasoning revived by Jonsen and Toulmin, plays in ordinary moral reasoning. I address the question: 'What is the evidence for contemporary casuistry's claim that everyday moral reasoning is casuistic in nature?' The paper begins with a description of the casuistic method, and then reviews the empirical arguments Jonsen and Toulmin offer to show that every-day moral decision-making is casuistic. Finally, I present the results of qualitative research conducted with 15 general practitioners (GPs) in South Australia, focusing on the ways in which these GP participants used stories and anecdotes in their own moral reasoning. This research found that the GPs interviewed did use a form of casuistry when talking about ethical dilemmas. However, the GPs' homespun casuistry often lacked one central element of casuistic reasoning--clear paradigm cases on which to base comparisons. I conclude that casuistic reasoning does appear to play a role in every-day moral decision-making, but that it is a more subdued role than perhaps casuists would like.
Simulation of gas flow in micro-porous media with the regularized lattice Boltzmann method
Wang, Junjian; Kang, Qinjun; Wang, Yuzhu; ...
2017-06-01
One primary challenge for prediction of gas flow in the unconventional gas reservoir at the pore-scale such as shale and tight gas reservoirs is the geometric complexity of the micro-porous media. In this paper, a regularized multiple-relaxation-time (MRT) lattice Boltzmann (LB) model is applied to analyze gas flow in 2-dimensional micro-porous medium reconstructed by quartet structure generation set (QSGS) on pore-scale. In this paper, the velocity distribution inside the porous structure is presented and analyzed, and the effects of the porosity and specific surface area on the rarefied gas flow and apparent permeability are examined and investigated. The simulation resultsmore » indicate that the gas exhibits different flow behaviours at various pressure conditions and the gas permeability is strongly related to the pressure. Finally, the increased porosity or the decreased specific surface area leads to the increase of the gas apparent permeability, and the gas flow is more sensitive to the pore morphological properties at low-pressure conditions.« less
Impact of Ada in the Flight Dynamics Division: Excitement and frustration
NASA Technical Reports Server (NTRS)
Bailey, John; Waligora, Sharon; Stark, Mike
1993-01-01
In 1985, NASA Goddard's Flight Dynamics Division (FDD) began investigating how the Ada language might apply to their software development projects. Although they began cautiously using Ada on only a few pilot projects, they expected that, if the Ada pilots showed promising results, they would fully transition their entire development organization from FORTRAN to Ada within 10 years. However, nearly 9 years later, the FDD still produces 80 percent of its software in FORTRAN, despite positive results on Ada projects. This paper reports preliminary results of an ongoing study, commissioned by the FDD, to quantify the impact of Ada in the FDD, to determine why Ada has not flourished, and to recommend future directions regarding Ada. Project trends in both languages are examined as are external factors and cultural issues that affected the infusion of this technology. This paper is the first public report on the Ada assessment study, which will conclude with a comprehensive final report in mid 1994.
Towards a geology of evidence-based practice--a discussion paper.
Rolfe, Gary; Gardner, Lyn
2006-09-01
We begin this paper with a consideration of the significance of a historical perspective in presentations of evidence-based practice in the nursing and medical literature. We suggest that whereas writers often produce coherent historical narratives as justification for particular views of the nature of EBP, an examination of its origins reveals no such signs of historical development or progress in our conception or understanding of it. We then explore alternative modes of thought for attempting to understand and critique the variety of definitions and descriptions of EBP to be found in the literature. We eventually reject the linear mode of historical thinking in favour of Deleuze's notion of rhizomatic thought and the metaphor of geology. Finally, we employ the rhizomatic mode of thinking and writing to construct a geology of evidence-based practice which attempts to expose and embrace contradictions in definitions and uses of the term rather than discount them in an authorised historical narrative written from the perspective of the dominant discourse.

Kurt Lewin, the originator of action research, proposed that it was valuable not only for innovating change, but also the process of change could lead to new insights into the nature of the problem that was being tackled. This action research project developed and evaluated a teaching model that aimed to help RGN (registered general nurse) students to bridge the theory-practice gap. During the course of this work, the possible reasons for a theory-practice gap started to become clear. This paper provides a discussion of these factors. The viewpoint for this discussion is that of the student nurse. The student is assumed to 'own' the problem and it is from her perspective that the theory-practice gap is analysed. The paper includes a critical examination of books, lectures, the school curriculum and ward nursing practice. Finally, possible solutions to the theory-practice problem are discussed and it is hoped that these will provide a rational basis for tackling the problem.
Breast-feeding: the role of multinational corporations in Latin America.
Bader, M B
1976-01-01
The decline in birthrates in the developed countries of the world has forced multinational corporations engaged in the production of infant formula to seek out new markets in the developing countries, where burgeoning population rates potentially guarantee the long-term profitability of these corporations. This development, ostensibly benign and nutritionally advantageous to infants in developing countries, has serious public health consequences, due to the high relative cost of purchased formula and the paucity of hygienic facilities essential to the sterile preparation of bottle formula. This paper delineates in detail economic and contraceptive advantages of breast-feeding, and examines the role of health personnel and multinational advertising techniques which have catalyzed the decline in breast-feeding. In addition, the paper focuses on the question of cultural imperialism and current efforts to regulate the multinational firms through both United Nations groups and stock-holders' suits. Finally, some suggestions are made concerning ameliorative public policy approaches to the breast-feeding controversy.
The re-emergence of the minimal running shoe.

The running shoe has gone through significant changes since its inception. The purpose of this paper is to review these changes, the majority of which have occurred over the past 50 years. Running footwear began as very minimal, then evolved to become highly cushioned and supportive. However, over the past 5 years, there has been a reversal of this trend, with runners seeking more minimal shoes that allow their feet more natural motion. This abrupt shift toward footwear without cushioning and support has led to reports of injuries associated with minimal footwear. In response to this, the running footwear industry shifted again toward the development of lightweight, partial minimal shoes that offer some support and cushioning. In this paper, studies comparing the mechanics between running in minimal, partial minimal, and traditional shoes are reviewed. The implications for injuries in all 3 conditions are examined. The use of minimal footwear in other populations besides runners is discussed. Finally, areas for future research into minimal footwear are suggested.

The rapid advances of computer technologies have created a new e-learner generation of "Homo-zappien" students that think and learn differently. Digital gaming is an effective, fun, active, and encouraging way of learning, providing immediate feedback and measurable process. Within the context of ongoing reforms in medical education, specially designed digital games, a form of active learning, are effective, complementary e-teaching/learning resources. To examine the effectiveness of the use of specially designed digital games for student satisfaction and for measurable academic improvement. One hundred fourteen students registered in first-year pathology Medicine 102 had 8 of 16 lecture sessions reviewed in specially designed content-relevant digital games. Performance scores to relevant content sessions were analyzed at midterm and final examinations. Seventy-one students who registered in second-year pathology Medicine 202 were exposed to the games only during the final examination, with the midterm examination serving as an internal matched-control group. Outcome measures included performance at midterm and final examinations. Paired 2-tailed t test statistics compared means. A satisfaction survey questionnaire of yes or no responses analyzed student engagement and their perceptions to digital game-based learning. Questions relevant to the game-play sessions had the highest success rate in both examinations among 114 first-year students. In the 71 second-year students, the examination scores at the end of the final examination were significantly higher than the scores on the midterm examination. Positive satisfaction survey noted increased student engagement, enhanced personal learning, and reduced student stress. Specially constructed digital games-based learning in undergraduate pathology courses showed improved academic performance as measured by examination test scores with increased student satisfaction and engagement.

Health provider racial/ethnic bias and its relationship to clinical decision-making is an emerging area of research focus in understanding and addressing ethnic health inequities. Examining potential racial/ethnic bias among medical students may provide important information to inform medical education and training. This paper describes the development, pretesting and piloting of study content, tools and processes for an online study of racial/ethnic bias (comparing Māori and New Zealand European) and clinical decision-making among final year medical students in New Zealand (NZ). The study was developed, pretested and piloted using a staged process (eight stages within five phases). Phase 1 included three stages: 1) scoping and conceptual framework development; 2) literature review and identification of potential measures and items; and, 3) development and adaptation of study content. Three main components were identified to assess different aspects of racial/ethnic bias: (1) implicit racial/ethnic bias using NZ-specific Implicit Association Tests (IATs); (2) explicit racial/ethnic bias using direct questions; and, (3) clinical decision-making, using chronic disease vignettes. Phase 2 (stage 4) comprised expert review and refinement. Formal pretesting (Phase 3) included construct testing using sorting and rating tasks (stage 5) and cognitive interviewing (stage 6). Phase 4 (stage 7) involved content revision and building of the web-based study, followed by pilot testing in Phase 5 (stage 8). Materials identified for potential inclusion performed well in construct testing among six participants. This assisted in the prioritisation and selection of measures that worked best in the New Zealand context and aligned with constructs of interest. Findings from the cognitive interviewing (nine participants) on the clarity, meaning, and acceptability of measures led to changes in the final wording of items and ordering of questions. Piloting (18 participants) confirmed the overall functionality of the web-based questionnaire, with a few minor revisions made to the final study. Robust processes are required in the development of study content to assess racial/ethnic bias in order to optimise the validity of specific measures, ensure acceptability and minimise potential problems. This paper has utility for other researchers in this area by informing potential development approaches and identifying possible measurement tools.

The third and final discussion paper of the German Network of Health Services Research's (DNVF) "Qualitative Methods Working Group" demonstrates methods for the evaluation and quality of qualitative research in health services research. In this paper we discuss approaches described in evaluating qualitative studies, including: an orientation to the general principles of empirical research, an approach-specific course of action, as well as procedures based on the research-process and criteria-oriented approaches. Divided into general and specific aspects to be considered in a qualitative study quality evaluation, the central focus of the discussion paper undertakes an extensive examination of the process and criteria-oriented approaches. The general aspects include the participation of relevant groups in the research process as well as ethical aspects of the research and data protection issues. The more specific aspects in evaluating the quality of qualitative research include considerations about the research interest, research questions, and the selection of data collection methods and types of analyses. The formulated questions are intended to guide reviewers and researchers to evaluate and to develop qualitative research projects appropriately. The intention of this discussion paper is to ensure a transparent research culture, and to reflect on and discuss the methodological and research approach of qualitative studies in health services research. With this paper we aim to initiate a discussion on high quality evaluation of qualitative health services research. © Georg Thieme Verlag KG Stuttgart · New York.

Gender as a variable in the assessment of final year degree-level communication skills.
Wiskin, Connie M D; Allan, Teresa F; Skelton, John R
2004-02-01
To investigate possible bias due to gender combination of students, role players and examiners in a high-stakes assessment. Valid oral interactive contextualized examinations (VOICEs) is a long-station OSCE-style exam in general practice (GP). At the time of writing it consisted of 65% of the student's final GP mark. In the VOICE, students undertake six tasks--four vivas and two role-plays. "Patient" roles are taken by professional role players who work regularly on the undergraduate curriculum. During the role-play, the student's clinical competence is assessed by an observing GP examiner. The communication skills marks are awarded by the role player and the examiner together, by negotiation. Data have been recorded detailing the role player's initial marks, the examiner's initial marks and their final (awarded) agreed marks for 1024 consultations. 512 final year medical students, 28 role players and 48 examiners. There were no inclusion or exclusion criteria. All those present on exam day became part of the data. There was a significant relationship between gender and performance for some, but not all, stations. Correlations for multiple comparisons removed the significance. Female students perform better across the board than male students. While not always significant, this did affect grading. There was no significant association between the genders of role players and examiners with the question choices. There has been a significant worsening of male results since 1999. Differences exist in the way that pairs of mixed or single genders score students.

This paper presents the main features of contemporary diagnostic systems which are implemented into the SCAN--modern and semi-structured diagnostic interview. The concepts of further development of the classifications, rationale for operationalized diagnostic criteria and for the divisional approach to mental diagnoses will be in focus. The structure and components of SCAN ver. 2.1 (WHO), i.e. Present State Examination--10th edition, Item Group Checklist, Clinical History Schedule, Glossary of Definitions and computer software with the diagnostic algorithm: I-Shell, as well as rules for a reliable use of diagnostic rating scales, will be discussed within the scope of this paper. The materials and training sets necessary for the learning of proper use of the SCAN, especially training sets for SCAN Training Centers and the Reference Manual--a form of guidebook for SCAN shall be introduced. Finally the paper will present evidence that SCAN is an instrument feasible in different cultural settings. Reliability and validity data of SCAN will also be dealt with indicating that SCAN could be widely used in research studies as well as in everyday clinical practice facilitating more detailed diagnostic approach to a patient.

The policy implications of a 1996 national nursing survey on the allocation of publication credit form of this paper. An earlier article (Butler & Ginn, 1997) describes and analyzes the outcome of the survey; the purpose here is to draw on that analysis, and on the relevant literature, to propose a starting place for discussion within the specialty of oncology and the nursing profession regarding assignment of credit for various contributions to collaborative scholarly work. After identifying the growing need for such a discussion and briefly highlighting the findings of the survey, the paper goes on to examine unacceptable practices in scholarly work and identify issues which should be resolved before collaborative work is undertaken. The final portion of the paper makes tentative suggestions as to principles and guidelines which might be applied to avoid disputes about the value of different contributions to a collaborative project. It is emphasized that the intention is not to advocate acceptance of the guidelines suggested here, but to create sufficient interest so that an approach to allocation of publication credit may be developed which will be consistent and relevant to the needs of the nursing profession.
Long-term/strategic scenario for reusable booster stages

Sippel, Martin; Manfletti, Chiara; Burkhardt, Holger
2006-02-01
This paper describes the final design status of a partially reusable space transportation system which has been under study for five years within the German future launcher technology research program ASTRA. It consists of dual booster stages, which are attached to an advanced expendable core. The design of the reference liquid fly-back boosters (LFBB) is focused on LOX/LH2 propellant and a future advanced gas-generator cycle rocket motor. The preliminary design study was performed in close cooperation between DLR and the German space industry. The paper's first part describes recent progress in the design of this reusable booster stage. The second part of the paper assesses a long-term, strategic scenario of the reusable stage's operation. The general idea is the gradual evolution of the above mentioned basic fly-back booster vehicle into three space transportation systems performing different tasks: Reusable First Stage for a small launcher application, successive development to a fully reusable TSTO, and booster for a super-heavy-lift rocket to support an ambitious space flight program like manned Mars missions. The assessment addresses questions of technical sanity, preliminary sizing and performance issues and, where applicable, examines alternative options.

The report of an imaging procedure is a critical component of an examination, being the final and often the only communication from the interpreting physician to the referring or treating physician. Very limited evidence and few recommendations or guidelines on reporting imaging studies are available; therefore, an European position statement on how to report nuclear cardiology might be useful. The current paper combines the limited existing evidence with expert consensus, previously published recommendations as well as current clinical practices. For all the applications discussed in this paper (myocardial perfusion, viability, innervation, and function as acquired by single photon emission computed tomography and positron emission tomography or hybrid imaging), headings cover laboratory and patient demographics, clinical indication, tracer administration and image acquisition, findings, and conclusion of the report. The statement also discusses recommended terminology in nuclear cardiology, image display, and preliminary reports. It is hoped that this statement may lead to more attention to create well-written and standardized nuclear cardiology reports and eventually lead to improved clinical outcome.

The problematization of medical tourism: a critique of neoliberalism.
Smith, Kristen
2012-04-01
The past two decades have seen the extensive privatisation and marketisation of health care in an ever reaching number of developing countries. Within this milieu, medical tourism is being promoted as a rational economic development strategy for some developing nations, and a makeshift solution to the escalating waiting lists and exorbitant costs of health care in developed nations. This paper explores the need to problematize medical tourism in order to move beyond one dimensional neoliberal discourses that have, to date, dominated the arena. In this problematization, the paper discusses a range of understandings and uses of the term 'medical tourism' and situates it within the context of the neoliberal economic development of health care internationally. Drawing on theory from critical medical anthropology and health and human rights perspectives, the paper critically analyzes the assumed independence between the medical tourism industry and local populations facing critical health issues, where social, cultural and economic inequities are widening in terms of access, cost and quality of health care. Finally, medical tourism is examined in the local context of India, critiquing the increasingly indistinct roles played by government and private sectors, whilst linking these shifts to global market forces. © 2012 Blackwell Publishing Ltd.
How reliable are odour assessments?
Bokowa, A; Beukes, J A
2012-01-01
This paper will demonstrate the differences found in odour test results, when odour sampling is performed at the same sources by two different consultants. By examining two case studies, this paper will highlight that the difference between the results can be significant. Both studies are based on odour sampling programs determining the odour removal efficiency of odour control units installed at two different facilities: a pet food facility and an oil/grease recycling facility. The first study is based on odour measurements at the inlet and outlet of the unit installed by Applied Plasma Physics AS at the pet food facility. Odour assessments were performed by two separate consultants at the same time. The second study is based on testing of the odour removal effectiveness of two units: a scrubber and a biofilter at an oil/grease recycling facility. During this study two odour sampling programs were performed by two consultants at different times, but under the same process conditions. This paper will show how varying results can play a role in choosing the adequate odour control technologies. The final results suggest that although, an odour control unit may appear to be insufficient, it actually is successful at removing the odours.
Biological challenges of true space settlement

Mankins, John C.; Mankins, Willa M.; Walter, Helen
2018-05-01
"Space Settlements" - i.e., permanent human communities beyond Earth's biosphere - have been discussed within the space advocacy community since the 1970s. Now, with the end of the International Space Station (ISS) program fast approaching (planned for 2024-2025) and the advent of low cost Earth-to-orbit (ETO) transportation in the near future, the concept is coming once more into mainstream. Considerable attention has been focused on various issues associated with the engineering and human health considerations of space settlement such as artificial gravity and radiation shielding. However, relatively little attention has been given to the biological implications of a self-sufficient space settlement. Three fundamental questions are explored in this paper: (1) what are the biological "foundations" of truly self-sufficient space settlements in the foreseeable future, (2) what is the minimum scale for such self-sustaining human settlements, and (3) what are the integrated biologically-driven system requirements for such settlements? The paper examines briefly the implications of the answers to these questions in relevant potential settings (including free space, the Moon and Mars). Finally, this paper suggests relevant directions for future research and development in order for such space settlements to become viable in the future.

This paper will explore the difficulties of deep reductions by examining the technical verification challenges. At each step on the road to low numbers, the verification required to ensure compliance of all parties will increase significantly. Looking post New START, the next step will likely include warhead limits in the neighborhood of 1000 (Pifer 2010). Further reductions will include stepping stones at 100’s of warheads, and then 10’s of warheads before final elimination could be considered of the last few remaining warheads and weapons. This paper will focus on these three threshold reduction levels, 1000, 100’s, 10’s. For each, themore » issues and challenges will be discussed, potential solutions will be identified, and the verification technologies and chain of custody measures that address these solutions will be surveyed. It is important to note that many of the issues that need to be addressed have no current solution. In these cases, the paper will explore new or novel technologies that could be applied. These technologies will draw from the research and development that is ongoing throughout the national lab complex, and will look at technologies utilized in other areas of industry for their application to arms control verification.« less

This paper explores the role of silence in Spain's post-dictatorship memory politics. More specifically, the paper examines the forgotten Spanish colonial past in North Africa vis-à-vis the so-called pact of silence that accompanied Spain's transition to democracy after the Franco dictatorship. Drawing on various theoretical approaches in relation to collective memory, traditionally assumed associations between silence and forgetting are questioned. As is argued, silence may nurture and preserve memory just as it may also feed into forgetting. In the former case, silence typically enshrouds a living memory of a past that still weighs on the present, as the pact of silence in Spain clearly illustrates. In the latter case, silence signals a past perceived as already left behind and alien to society's current problems, as is the case of the Spanish colonial past in North Africa. In order to further explore the latter case, the notion of banal silence is introduced. Such notion points to cases where silence over certain contentious historical issues goes unnoticed by society, thus becoming naturalized. The paper concludes with some final reflexions on memory, banal silence and political change.

After a disaster, the media typically focus on who is to blame. However, relatively little is known about how the narrative of blame plays out in media coverage of the release of official disaster reports. This paper examines coverage by two Australian newspapers (The Courier-Mail and The Australian) of the release of the Queensland Floods Commission of Inquiry's Interim Report and its Final Report to identify whether and how the news frame of blame was used. Given the absence of blame in the Final Report, the newspapers resorted to the frame of 'failure' in news and feature articles, while continuing to raise questions in editorials and opinion pieces about who was to blame. This study argues that situating coverage of the report within the news frame of failure and questioning who was to blame for the disaster limited the media's ability to facilitate a discussion about the prevention of similar disasters in the future. © 2014 The Author(s).

Owing to the high viscosity of sodium silicate solution, fly ash geopolymer has the problems of low workability and rapid setting time. Therefore, the effect of chemical admixtures on the properties of fly ash geopolymer was studied to overcome the rapid set of the geopolymer in this paper. High-calcium fly ash and alkaline solution were used as starting materials to synthesize the geopolymer. Calcium chloride, calcium sulfate, sodium sulfate, and sucrose at dosages of 1wt% and 2wt% of fly ash were selected as admixtures based on concrete knowledge to improve the properties of the geopolymer. The setting time, compressive strength, and degree of reaction were recorded, and the microstructure was examined. The results show that calcium chloride significantly shortens both the initial and final setting times of the geopolymer paste. In addition, sucrose also delays the final setting time significantly. The degrees of reaction of fly ash in the geopolymer paste with the admixtures are all higher than those of the control paste. This contributes to the obvious increases in compressive strength.

The formation and stabilization of amorphous calcium carbonate (ACC) is an active area of research owing to the presence of stable ACC in various biogenic minerals. In this paper, the synthesis of calcium carbonate (CaCO3) under the participation of methotrexate (MTX) via a facile gas diffusion route was reported. The results indicated that the addition of MTX can result in the phase transformation of CaCO3, and then two kinds of hybrids, i.e., MTX-vaterite and stable MTX-ACC came into being. Interestingly, the functional agent MTX served as both the target anticancer drug loaded and effective complexation agents to modify and control the morphology of final samples. The examination of MTX-ACC biodegradation process revealed that the collapse of MTX-ACC nanoparticles was due to the synergistic effect of drug release and the phase transformation. Finally, our study also proved that MTX-ACC exhibited the most excellent suppressing function on the viability of cancer cells, especially after long-time duration. Copyright © 2016.

The Composite Infrared Spectrometer (CIRS) on-board Cassini consists of two interferometers: a conventional Michelson for the mid-infrared; and a Martin-Puplett type in the far-infrared employing wire grid polarizers to split, recombine and analyze the radiation. The far-IR focal plane (FP1) assembly uses two thermopile detectors to measure the final transmitted and reflected beams at the polarizer-analyzer: if one fails, the interferometer can still operate, albeit with a lower efficiency. The combined effect is for good response from 10 to 300/cm, and declining response to 600/cm. This paper will examine in-flight performance of the far-IR interferometer, including NESR and response. Regular noise spikes, resulting from pickup from other electrical sub-systems has been found on the CIRS interferograms, and the removal of these effects is discussed. The radiometric calibration is described, and then we show how the calibration was applied to science data taken during the Jupiter flyby of December 2000. Finally, we discuss signal-to-noise on the calibrated spectra, emphasizing limitations of the current instrument and the potential for improvement in future missions.

This paper presents Hurst exponent signatures from time series of aggregate price indices for the US over the 1975-2011 time period. Though all highly aggregated, these indices include both broad measures of consumer and producer prices. The constellation of prices evolves as a complex system throughout processes of production and distribution, culminating in the final delivery of output to consumers. Massive feedback characterizes this system, where the demand for consumable output determines the demand for the inputs used to produce it, and supply scarcities for the necessary inputs in turn determine the supply of the final product. Prices in both factor and output markets are jointly determined by interdependent supply and demand conditions. Fractal examination of the interplay among market prices would be of interest regardless, but added interest arises from the consideration of how these markets respond to external shocks over the business cycle, particularly monetary expansion. Because the initial impact of monetary injection is localized in specific sectors, the way the impact on prices diffuses throughout the economy is of special interest.

Theory-driven text analysis has made extensive use of psychological concept dictionaries, leading to a wide range of important results. These dictionaries have generally been applied through word count methods which have proven to be both simple and effective. In this paper, we introduce Distributed Dictionary Representations (DDR), a method that applies psychological dictionaries using semantic similarity rather than word counts. This allows for the measurement of the similarity between dictionaries and spans of text ranging from complete documents to individual words. We show how DDR enables dictionary authors to place greater emphasis on construct validity without sacrificing linguistic coverage. We further demonstrate the benefits of DDR on two real-world tasks and finally conduct an extensive study of the interaction between dictionary size and task performance. These studies allow us to examine how DDR and word count methods complement one another as tools for applying concept dictionaries and where each is best applied. Finally, we provide references to tools and resources to make this method both available and accessible to a broad psychological audience.
Discriminating different Z{sup '}'s via asymmetries at the LHC

In practice the asymmetry, which is defined based on the angular distribution of the final states in scattering or decay processes, can be utilized to scrutinize underlying dynamics in and/or beyond the standard model (BSM). As one of the possible BSM physics which might be discovered early at the LHC, extra neutral gauge bosons Z{sup '}'s are theoretically well motivated. Once Z{sup '}'s are discovered at the LHC, it is crucial to discriminate different Z{sup '}'s in various BSM. In principle such a task can be accomplished by measuring the angular distribution of the final states which are produced viamore » Z{sup '}-mediated processes. In the real data analysis, asymmetry is always adopted. In the literature several asymmetries have been proposed at the LHC. Based on these works, we stepped further on to study how to optimize the asymmetries in the left-right model and the sequential standard model, as the examples of BSM. In this paper, we examined four kinds of asymmetries, namely, rapidity-dependent forward-backward asymmetry, oneside forward-backward asymmetry, central charge asymmetry, and edge charge asymmetry (see text for details), with l{sup +}l{sup -} (l=e, {mu}), bb, and tt as the final states. In the calculations with bb and tt final states, the QCD-induced higher-order contributions to the asymmetric cross section were also included. For each kind of final state, we estimated the four kinds of asymmetries and especially the optimal cut usually associated with the definition of the asymmetry. Our numerical results indicated that the capacity to discriminate Z{sup '} models can be improved by imposing the optimal cuts.« less
A class of renormalised meshless Laplacians for boundary value problems
NASA Astrophysics Data System (ADS)
Basic, Josip; Degiuli, Nastia; Ban, Dario
2018-02-01
A meshless approach to approximating spatial derivatives on scattered point arrangements is presented in this paper. Three various derivations of approximate discrete Laplace operator formulations are produced using the Taylor series expansion and renormalised least-squares correction of the first spatial derivatives. Numerical analyses are performed for the introduced Laplacian formulations, and their convergence rate and computational efficiency are examined. The tests are conducted on regular and highly irregular scattered point arrangements. The results are compared to those obtained by the smoothed particle hydrodynamics method and the finite differences method on a regular grid. Finally, the strong form of various Poisson and diffusion equations with Dirichlet or Robin boundary conditions are solved in two and three dimensions by making use of the introduced operators in order to examine their stability and accuracy for boundary value problems. The introduced Laplacian operators perform well for highly irregular point distribution and offer adequate accuracy for mesh and mesh-free numerical methods that require frequent movement of the grid or point cloud.

The experimental results of Kocsis et al., Mahler et al. and the proposed experiments of Morley et al. show that it is possible to construct “trajectories” in interference regions in a two-slit interferometer. These results call for a theoretical re-appraisal of the notion of a “quantum trajectory” first introduced by Dirac and in the present paper we re-examine this notion from the Bohm perspective based on Hamiltonian flows. In particular, we examine the short-time propagator and the role that the quantum potential plays in determining the form of these trajectories. These trajectories differ from those produced in a typical particlemore » tracker and the key to this difference lies in the active suppression of the quantum potential necessary to produce Mott-type trajectories. We show, using a rigorous mathematical argument, how the active suppression of this potential arises. Finally we discuss in detail how this suppression also accounts for the quantum Zeno effect.« less

Internationalization is a matter of committed decision-making that starts with export marketing, in which an organization tries to diagnose and use opportunities in target markets based on realistic evaluation of internal strengths and weaknesses with analysis of macro and microenvironments in order to gain presence in other countries. A developed model for export and international marketing of pharmaceutical companies is introduced. The paper reviews common theories of the internationalization process, followed by examining different methods and models for assessing preparation for export activities and examining conceptual model based on a single case study method on a basket of seven leading domestic firms by using mainly questionares as the data gathering tool along with interviews for bias reduction. Finally, in keeping with the study objectives, the special aspects of the pharmaceutical marketing environment have been covered, revealing special dimensions of pharmaceutical marketing that have been embedded within the appropriate base model. The new model for international activities of pharmaceutical companies was refined by expert opinions extracted from result of questionnaires. PMID:24250597

In view of the high impact of materialistic orientation among children and adolescents, financial educational programs are provided as preventive measures. Without a clear framework, it is impossible to evaluate these programs. The goals of this paper are threefold. Firstly, the phenomena related to adolescent materialistic orientation and its associated problems in Hong Kong are examined. Secondly, the concept of financial education as a preventive measure is reviewed. Both board and narrow definitions of money literacy are examined. A framework on money literacy for children and adolescents as a founding stone for financial education is proposed. The framework finds its support from a typology proposed by the authors and results from an integration of research findings on dimensions of the concepts of money and success. Finally, curriculum units for Grades 7 to 9 students in a positive youth development program (the Project P.A.T.H.S.) are developed using the framework. PMID:22194664
