2007-01-01

The aim of this review is to discuss the current state of research on the concept of neurosis across cultures and to document the advances made in this field over the previous year. There has been a significant alteration in the concept of neurosis in most cultures, with the relative abandonment of the term 'neurosis' and replacing the concept with that of common mental disorders. The state of research on the aetiopathogenesis of neurosis has moved towards neurobiological, neurophysiological and genetic factors. Neuroticism as a personality trait has retained its role in the development of neurotic disorders. The epidemiological studies on neurotic disorders are equivocal across cultures. Besides, studies on clinical presentation of common mental disorders, somatization and abnormal illness behaviour show some cultural variations. Though there are no significant advances in the management of neurosis equivalents, it seems that the specific serotonin receptor inhibitors may have a role in management of these conditions. The recent literature shows acceptance of common mental disorders across cultures replacing neurotic disorders. Other conceptual equivalents of neurosis are seen in somatoform disorders, somatization and abnormal illness behaviour. Some traditional culture-bound neurotic syndromes and idioms of distress persist.

Fundamental knowledge of microscopic anatomy and pathology has always been an essential part in medical education. The traditional didactic concept comprises theoretical and practical lessons using a light microscope and glass slides. High-speed Internet connections and technical improvement in whole-slide digital microscopy (commonly termed "virtual microscopy") provide a new and attractive approach for both teachers and students. High picture quality and unlimited temporal and spatial availability of histology samples from different fields are key advantages of web-based digital microscopy. In this report we discuss the technical requirements, system efficiency, optical resolution and didactic concept. Furthermore, we present a review of the experience gained in the course of one year based on an analysis of student acceptance. Three groups with a total of 192 students between the 3rd and 5th year of medical studies attending the practical courses of general and advanced histopathology had access to both glass-mounted and digitalized slides. Prior to exams, students were asked to answer an anonymous questionnaire. The results of the study reflect the high acceptance and intensive use of the web-based digital histology by students, thus encouraging the development of further Web-based learning strategies for the teaching of histology and pathology. 2010 Elsevier GmbH.

2017-01-01

This summary document and accompanying technology artifacts satisfy the second of three Research Transition Products (RTPs) defined in the ATD-3 Applied Traffic Flow Management (ATFM) Research Transition Team (RTT) Plan. This transfer consists of NASA's Multi-Flight Common Route (MFCR) research for efficient route corrections for en-route weather avoidance. The MFCR concept builds on the experience of the legacy Dynamic Weather Routes (DWR) and focuses on a better balance of potential savings with ATC acceptability, common route corrections options for multiple flights on similar routings, and better use of existing and/or modern automation for communication and coordination of route change options. All of these capabilities are expected to improve system performance significantly in terms of actual delay-reducing clearances issued to flights compared to that of the DWR tool and operating concept.

Evaluation of Students' Conceptual Understanding of Malaria

2010-12-01

In this study, a two-tier diagnostic test for understanding malaria was developed and administered to 314 Bruneian students in Year 12 and in a nursing diploma course. The validity, reliability, difficulty level, discriminant indices, and reading ability of the test were examined and found to be acceptable in terms of measuring students' understanding and identifying alternative conceptions with respect to malaria. Results showed that students' understanding of malaria was high for content, low for reasons, and limited and superficial for both content and reasons. The instrument revealed several common alternative conceptual understandings students' hold about malaria. The MalariaTT2 instrument developed could be used in classroom lessons for challenging alternative conceptions and enhancing conceptions of malaria.

The essence of frailty: A systematic review and qualitative synthesis on frailty concepts and definitions.

One of the major threats looming over the growing older population is frailty. It is a distinctive health state characterised by increased vulnerability to internal and external stressors. Although the presence of frailty is well acknowledged, its concept and operationalisation are hampered by the extraordinary phenotypical and biological complexity. Yet, a widely accepted conception is needed to offer tailored policies and approaches. The ADVANTAGE Group aims to analyse the diverse frailty concepts to uncover the essence of frailty as a basis for a shared understanding. A systematic literature review was performed on frailty concepts and definitions from 2010 onwards. Eligible publications were reviewed using concept analysis that led to the extraction of text data for the themes "definition", "attributes", "antecedents", "consequences", and "related concepts". Qualitative description was used to further analyse the extracted text passages, leading to inductively developed categories on the essence of frailty. 78 publications were included in the review, and 996 relevant text passages were extracted for analysis. Five components constituted a comprehensive definition: vulnerability, genesis, features, characteristics, and adverse outcomes. Each component is described in more detail by a set of defining and explanatory criteria. An underlying functional perspective of health or its impairments is most compatible with the entity of frailty. The recent findings facilitate a focus on the relevant building blocks that define frailty. They point to the commonalities of the diverse frailty concepts and definitions. Based on these components, a widely accepted broad definition of frailty comes into range. Copyright © 2018 European Federation of Internal Medicine. Published by Elsevier B.V. All rights reserved.

Safer conception strategies to reduce HIV transmission risk include antiretroviral therapy (ART) for HIV-positive partners, pre-exposure prophylaxis (PrEP) for HIV-negative partners, condomless sex limited to fertile periods, and home-based self-insemination. Resistance to taking treatment or cultural concerns may limit uptake of strategies and intervention success. Understanding the acceptability and preferences between different approaches is important to optimize service delivery. Between February-July 2013, 42 adults (21 HIV-positive and 21 HIV-negative) receiving primary care at Witkoppen Health and Welfare Centre in Johannesburg, South Africa, participated in focus group discussions or in-depth interviews. Themes were analyzed using a grounded theory approach. Acceptability of antiretroviral-based (ARV) strategies varied. Concerns over side effects, ARV treatment duration, and beliefs that treatment is only for the sick were common barriers, however desperation for a child was noted as a facilitator for uptake. HIV-negative men and HIV-positive women had favorable attitudes towards self-insemination, though paternity and safety concerns were raised. Self-insemination was generally preferred over PrEP by HIV-negative men, and ARV-based strategies were preferred by couples with HIV-negative female partners, despite concerns raised about condomless sex while virally suppressed. Knowledge about the fertile window was low. A strong counselling component will be required for effective uptake and adherence to safer conception services. PMID:26384950

Intimate relationship quality, self-concept and illness acceptance in those with multiple sclerosis.

PubMed

Wright, Thomas M; Kiropoulos, Litza A

2017-02-01

Lower levels of Intimate Relationship Quality (IRQ) have been found in those with Multiple Sclerosis (MS) compared to the general population. This study examined an MS sample to see whether IRQ was positively associated with self-concept, whether IRQ was positively associated with MS illness acceptance and whether IRQ was predicted by self-concept and illness acceptance. In this cross-sectional study, 115 participants with MS who were in an intimate relationship completed an online survey advertised on MS related websites. The survey assessed demographic variables, MS illness variables and levels of IRQ, self-concept and illness acceptance. Results revealed that IRQ was significantly positively associated with self-concept and with illness acceptance. Multiple hierarchical linear regression analysis revealed that, after controlling for illness duration and level of disability, self-concept significantly predicted IRQ but illness acceptance did not significantly predict IRQ. This study addressed several gaps and methodological flaws in the literature and was the first known to assess predictors of IRQ in those with MS. The results suggest that self-concept could be a potential target for individual and couple psychological interventions to improve IRQ and contribute to improved outcomes for those with MS.

The province and heritage of mankind reconsidered: A new beginning

NASA Technical Reports Server (NTRS)

Gabrynowicz, J. I.

1992-01-01

The central problem of our time -- one that is shared by all races and nationalities -- is to discover the things, the qualities, and interest that people have in common so that durable institutions can be designed for mankind's survival. The 'common heritage of mankind' and the 'province of all mankind' are different legal concepts developed in international space law during the last quarter of a century. Since the initial appearance of these provisions, controversy has arisen regarding their intent and meaning as applied to a nation's right to explore and use a common environment such as space or the high seas and a nation's obligation to share benefits derived from those environments with the rest of the world. As can be expected, different interpretations are currently competing for acceptance. This is so, in part, because, in the case of the Outer Space Treaty, although a general principle was articulated, rules for acceptance and application of the principles were not. In the case of the Moon and Sea Treaties, although an effort has been made to clarify both meaning and application, the articulations are still too vague for legal certainty. This paper focuses on the fact that these concepts are already currently available tools for the advancement of both global and U.S. interests but, because of the labyrinthine legal arguments that have been generated and some assumptions being held, they are in danger of being lost as such tools. The tendency of many observers in the U.S. to confuse the concept of 'province of all mankind' and 'common heritage of mankind' and to assume that both are incompatible with U. S. commercial space interests is also addressed. It is suggested that reconsidering these provisions can yield positions compatible with U.S. interests and that it can and should actively seek the use of these provisions as a basis for global cooperation and commercial benefit.

2014-06-01

Quality of structures, processes and outcome are commonly accepted as dimensions of quality management and quality assurance. Data of structures and processes are not published to date for German outpatient neurorehabilitation. Rehabilitative care and service providers are legally bound to apply concepts of quality management and quality assurance. The service providers pass recommendations, which have to be implemented by outpatient neurorehabilitation centres. Data analysis of existing structures and processes in outpatient neurorehabilitation centres are embedded as a part of a long-term multicentres outcome study. 22 outpatient neurorehabilitation centres participated in an online survey with 227 items using the google tool "Docs" between September and December 2011. Following issues were asked: general information about the centres (e. g. date of establishment, number of therapy places, kind of patients, responsible organization), utility supply contracts with service providers, local cooperation and networking, staff and equipment and appliances, treatment concepts, processes of therapy (e. g. individual and group therapy, frequency, concentration, planning), team processes, goals and team development, quality management and documentation. In the meantime outpatient centres of neurorehabilitation are well-established as care providers and commonly accepted by service providers. However a comprehensive availability does not exist. The results show comparable structures of the centres, what is mostly determined by the service provider audited regulatory framework. Different concepts result in different processes. There are a lot of hints with respect to different concepts in form and content to implement the legally obligated mandate. In general their work with context -factors is still a frequently unused potential. It can be countered by the therapeutic inclusion of the social and environmental living conditions of the patients. © Georg Thieme Verlag KG Stuttgart · New York.

Student Conceptions of Ionic Bonding: Patterns of thinking across three European contexts

NASA Astrophysics Data System (ADS)

Taber, Keith S.; Tsaparlis, Georgios; Nakiboğlu, Canan

2012-12-01

Previous research has reported that students commonly develop alternative conceptions in the core topic of chemical bonding. Research in England has reported that students there commonly demonstrate an alternative 'molecular' conceptual framework for thinking about ionic bonding: in terms of the formation of molecule-like ions pairs through electron transfer, which are internally bonded, but not bonded to other ions. The present study reports the use of translated versions of a diagnostic instrument to elicit the conceptions of bonding in NaCl (commonly used as the teaching example of an ionic compound) from two samples of students setting out on university courses in Greece and Turkey. The study reports that students in these two contexts displayed high levels of support for statements based upon the alternative conceptual framework identified in the English context. Students commonly develop similar alternative conceptions of ionic bonding in these three different educational contexts. The study also found some quite large differences in the specific response patterns across these three contexts, some of which could reflect specific features of the different curriculum contexts. The study reinforces the cross-national nature of the challenge of effectively teaching the abstract models of chemistry at the submicroscopic level. It also provides intriguing suggestions that a close study of the interactions between specific curriculum contexts and specific patterns in students' thinking offers much potential for identifying particular aspects of subject pedagogy that either support or impede the learning of accepted scientific models.

Objectives To explore the experiences of family carers who manage technical health procedures at home and describe their learning process. Design A qualitative study using grounded theory. Participants New Zealand family carers (21 women, 5 men) who managed technical health procedures such as enteral feeding, peritoneal dialysis, tracheostomy care, a central venous line or urinary catheter. In addition, 15 health professionals involved in teaching carers were interviewed. Methods Semistructured interviews were coded soon after completion and preliminary analysis influenced subsequent interviews. Additional data were compared with existing material and as analysis proceeded, initial codes were grouped into higher order concepts until a core concept was described. Interviewing continued until no new ideas emerged and concepts were well defined. Results The response of carers to the role of managing technical health procedures in the home is presented in terms of five dispositions: (1) Embracing care, (2) Resisting, (3) Reluctant acceptance, (4) Relinquishing and (5) Being overwhelmed. These dispositions were not static and carers commonly changed between them. Embracing care included cognitive understanding of the purpose and benefits of a procedure; accepting a ‘technical’ solution; practical management; and an emotional response. Accepting embrace is primarily motivated by perceived benefits for the recipient. It may also be driven by a lack of alternatives. Resisting or reluctant acceptance results from a lack of understanding about the procedure or willingness to manage it. Carers need adequate support to avoid becoming overwhelmed, and there are times when it is appropriate to encourage them to relinquish care for the sake of their own needs. Conclusions The concept of embracing care encourages health professionals to extend their attention beyond simply the practical aspects of technical procedures to assessing and addressing carers’ emotional and behavioural responses to health technology during the training process.

[Self esteem : concept analysis.

PubMed

Doré, Christina

2017-06-01

Self-esteem is an inner attitude at the base of the construction of personality and psychic balance in addition to be responsible of adaptive processes over the course of life. The concept of self-esteem is commonly used in several disciplines however, it seems that the consensus on its conceptualization and its operationalization is not yet reached. In this context, the concept analysis allows to address a phenomenon and to understand its use and its evolution from a unique disciplinary perspective. The aim of this article is therefore to analyze the concept of self esteem from a nursing perspective to identify : definitions of the term and related terms, attributes, model and limit cases proposed here within the community of mental health nurses, antecedents and consequents as well as the empirical references using the Walker and Avant method. The attributes identified allowing a deeper understanding of the concept are : the self-value, the self-acceptance, the self-efficacy, attitude towards oneself and finally, self-respect.

2006-01-01

Background Changes in self-concept are an important potential outcome for many interventions for people with long-term conditions. This study sought to identify and evaluate outcome questionnaires suitable for quantifying changes in self-concept in people with long-term conditions, in the context of treatment with acupuncture and Chinese medicine. Methods A literature search was followed by an evaluation of three questionnaires: The Wellbeing Questionnaire W-BQ12, the Patient Enablement Instrument (PEI), and the Arizona Integrative Outcome Scale (AIOS). A convenience sample of 23 people completed the questionnaires on two occasions and were interviewed about their experience and their questionnaire responses. All acupuncturists were interviewed. Results Changes in self-concept were common and emerged over time. The three questionnaires had different strengths and weaknesses in relation to measuring changes in self-concept. The generic AIOS had face validity and was sensitive to changes in self-concept over time, but it lacked specificity. The PEI was sensitive and specific in measuring these changes but had lower acceptability. The sensitivity of the W-BQ12 was affected by initial high scores (ceiling effect) and a shorter timescale but was acceptable and is suitable for repeated administration. The PEI and W-BQ12 questionnaires worked well in combination. Conclusion Changes in self-concept are important outcomes of complex interventions for people with long-term illness and their measurement requires carefully evaluated tools and long-term follow-up. The literature review and the analysis of the strengths and weaknesses of the questionnaires is a resource for other researchers. The W-BQ12 and the PEI both proved useful for this population and a larger quantitative study is planned. PMID:16539737

Degenerative lumbosacral stenosis in working dogs: current concepts and review.

PubMed

Worth, A J; Thompson, D J; Hartman, A C

2009-12-01

Degenerative lumbosacral stenosis (DLSS) is characterised by intervertebral disc degeneration, with secondary bony and soft-tissue changes leading to compression of the cauda equina. Large-breed, active and working dogs are the most commonly affected by DLSS. Specific manipulative tests allow the clinician to form a high suspicion of DLSS, and initiate investigation. Changes seen using conventional radiography are unreliable, and although contrast radiography represents an improvement, advanced imaging is accepted as the diagnostic method of choice. Treatment involves decompression and/or stabilisation procedures in working dogs, although conservative management may be acceptable in pet dogs with mild signs. Prognosis for return to work is only fair, and there is a high rate of recurrence following conventional surgery. Stabilisation procedures are associated with the potential for failure of the implant, and their use has not gained universal acceptance. A new surgical procedure, dorsolateral foramenotomy, offers a potential advance in the management of DLSS. everal aspects of the pathogenesis, heritability and optimal treatment approach remain uncertain.

Progress in Emission Efficiency of Organic Light-Emitting Diodes: Basic Understanding and Its Technical Application

2013-11-01

The technical history of when and how the basic understanding of the emission efficiency of organic light-emitting diodes (OLEDs) was established over the last 50 years is described. At first, our understanding of emission efficiency in single-crystal and thin-film electroluminescence (EL) devices in the early stages before the Eastman-Kodak breakthrough, that is, the introduction of the concept of multilayer structures, is examined. Then our contemplation travels from the Eastman-Kodak breakthrough towards the presently widely accepted concept of emission efficiency. The essential issues concerning the emission efficiency of OLEDs are summarized to help readers to obtain a common understanding of OLED efficiency problems, and detailed discussions on the primary factors that determine emission efficiency are given. Finally, some comments on remaining issues are presented.

Capacity, consent, and mental health legislation: time for a new standard?

O'Brien, Anthony J

2010-01-01

Recent international reforms in mental health legislation have introduced a capacity test as a criterion for civil commitment. There are proposals that a common test of incapacity should apply in both mental and physical health under a single legislative framework for all cases in which the normally accepted standard of informed consent for treatment is not met. Capacity is a complex concept, but can be reliably assessed in clinical practice. Nurses need to be involved in the policy debate about capacity and consent in mental health care.

DOCLIB: a software library for document processing

NASA Astrophysics Data System (ADS)

Jaeger, Stefan; Zhu, Guangyu; Doermann, David; Chen, Kevin; Sampat, Summit

2006-01-01

Most researchers would agree that research in the field of document processing can benefit tremendously from a common software library through which institutions are able to develop and share research-related software and applications across academic, business, and government domains. However, despite several attempts in the past, the research community still lacks a widely-accepted standard software library for document processing. This paper describes a new library called DOCLIB, which tries to overcome the drawbacks of earlier approaches. Many of DOCLIB's features are unique either in themselves or in their combination with others, e.g. the factory concept for support of different image types, the juxtaposition of image data and metadata, or the add-on mechanism. We cherish the hope that DOCLIB serves the needs of researchers better than previous approaches and will readily be accepted by a larger group of scientists.

Henderson, Emily J

2015-07-01

The Common Risk Factor Approach proposes that public health efforts can be improved by multiple agencies working together on a shared risk factor. The present study aimed to assess the acceptability to parents, dental practice staff and commissioners of the delivery of dietary advice in the dentistry setting in order to address obesity. Semi-structured focus groups with dental practice staff and one-to-one interviews with parents of pre-school children and public health commissioners involved in an oral health promotion initiative delivering dietary advice in dental surgeries. Data were analysed using the Framework Approach. General dental practice surgeries and pre-schools in areas of high deprivation in north-east England. Parents (n 4), dental practice staff (n 23) and one commissioner. All participants found acceptable the concept of delivering public health messages in non-conventional settings. Dental practice staff were concerned about the potential for conflicting messages and deprioritisation of oral health advice, and they identified practical barriers to delivery, such as lack of training. Parents were very apprehensive about the potential of such approaches to stigmatise overweight children, including bullying. Uncertainty over the causes of obesity led to confusion about its solutions and the roles of public health and health care. Major concerns about the implementation of the Common Risk Factor Approach were raised by parents and dental practice staff. Specific dietary guidance for both oral health and healthy weight, as well as further research into issues of suitability, feasibility and stigmatisation, are needed.

Lee, Sang-Ahm; Choi, Eun-Ju; Kwon, Soonhak; Eom, Soyong

2016-08-01

We aimed to determine whether adolescents with epilepsy (AWE) have a compromised self-concept, whether a lower self-concept is related to mental health, and whether there are sex differences in self-concept in AWE. A total of 179 AWE and 259 control adolescents without epilepsy participated in this cross-sectional, multicenter study. Self-concept was measured using the Harter's Self-Perception Profile for Children. Depressive symptoms and anxiety were assessed by the Hospital Anxiety Depression Scale (HADS). A group-by-sex interaction was evaluated using an analysis of covariance controlling for age. Adolescents with epilepsy had a lower level of self-concept, especially in domains of behavioral conduct (partial eta(2): 0.257) and social acceptance (partial eta(2): 0.116), than controls (p<0.05). The level of self-concept did not differ by sex in the group with epilepsy. A group-by-sex interaction effect was found on social acceptance (p=0.042). Unlike the control group, age was not correlated with self-concept in AWE. Physical appearance was negatively correlated with HADS-anxiety scores (r=-0.291, p<0.01) but only in girls with epilepsy. Epilepsy duration was correlated with social acceptance in boys (r=0.211, p<0.05) and physical appearance in girls (r=-0.249, p<0.05). Adolescents with epilepsy had a lower level of self-concept, especially in the domains of behavioral conduct and social acceptance, than controls. Sex differences in self-concept were identified in the control group but not in the group with epilepsy. Physical appearance was negatively correlated with anxiety in girls with epilepsy.

2015-02-01

The concept of cloud manufacturing is emerging as a new promising manufacturing paradigm, as well as a business model, which is reshaping the service-oriented, highly collaborative, knowledge-intensive and eco-efficient manufacturing industry. However, the basic concepts about cloud manufacturing are still in discussion. Both academia and industry will need to have a commonly accepted definition of cloud manufacturing, as well as further guidance and recommendations on how to develop and implement cloud manufacturing. In this paper, we review some of the research work and clarify some fundamental terminologies in this field. Further, we developed a cloud manufacturing systems which may serve as an application example. From a systematic and practical perspective, the key requirements of cloud manufacturing platforms are investigated, and then we propose a cloud manufacturing platform prototype, MfgCloud. Finally, a public cloud manufacturing system for small- and medium-sized enterprises (SME) is presented. This paper presents a new perspective for cloud manufacturing, as well as a cloud-to-ground solution. The integrated solution proposed in this paper, including the terminology, MfgCloud, and applications, can push forward this new paradigm from concept to practice.

[For a critical history of the concept of anxiety].

PubMed

Peter, Jean-Pierre

2012-06-01

Anxiety, tension, anguish... These are words, but first of all, states of the self. Accepted since the dawn of time by human distress and by the effort to understand them, they were taken back in hand by Psychopathology, established as a little dark concepts, and as such have become today so sovereign in the most ordinary way that their "reality" seems to be obvious. This recent acknowledgement is however the result of a history. To attempt to restore the original bases enables to find in it the old and well-thought-out acknowledgement in a common nature, the unknown factors of which were considered for a long time with familiarity and distance by common people as well as by doctors. This unconventional look, that we suggest to have here over a long period of time, allows us to restore, in the outermost bounds of Psychosomatics, all the ambiguities of a present notion which was at first physiological before appearing in psychiatric Nosology. It also means to take a certain distance from the medicalization of affects which, whatever we think, naturally come from our mortal condition.

Feasibility of tailoring of press formed thermoplastic composite parts

NASA Astrophysics Data System (ADS)

Sinke, J.

2018-05-01

The Tailor Made Blank concept is widely accepted in the production of sheet metal parts. By joining, adding and subtracting materials, and sometimes even applying different alloys, parts can be produced more efficiently by cost and/or weight, and new design options have been discovered. This paper is about the manufacture of press formed parts of Fibre Reinforced Thermoplastics and the evaluation whether the Tailoring concept, though adapted to the material behavior of FRTP, can be applied to these composites as well. From research, the first results and ideas are presented. One of the ideas is the multistep forming process, creating parts with thickness variations and combinations of fibre orientations that are usually not feasible using common press forming strategies. Another idea is the blending of different prepreg materials in one component. This might be useful in case of specific details, like for areas of mechanical fastening or to avoid carbon/metal contact, otherwise resulting in severe corrosion. In a brief overview, future perspectives of the potential of the Tailoring concept are presented.

The relativity of Darwinian populations and the ecology of endosymbiosis.

PubMed

Stencel, Adrian

If there is a single discipline of science calling the basic concepts of biology into question, it is without doubt microbiology. Indeed, developments in microbiology have recently forced us to rethink such fundamental concepts as the organism, individual, and genome. In this paper I show how microorganisms are changing our understanding of natural aggregations and develop the concept of a Darwinian population to embrace these discoveries. I start by showing that it is hard to set the boundaries of a Darwinian population, and I suggest thinking of a Darwinian population as a relative property of a Darwinian individual. Then I argue, in contrast to the commonly held view, that Darwinian populations are multispecies units, and that in order to accept the multispecies account of Darwinian populations we have to separate fitness from natural selection. Finally, I show how all these ideas provide a theoretical framework leading to a more precise understanding of the ecology of endosymbiosis than is afforded by poetic metaphors such as 'slavery'.

The Orbital Debris Problem and the Challenges for Environment Remediation

NASA Technical Reports Server (NTRS)

Liou, J.-C.

2014-01-01

LEO debris population will continue to increase even with a good implementation of the commonly-adopted mitigation measures. The root-cause of the increase is catastrophic collisions involving large/massive intact objects (rocket bodies or spacecraft). The major mission-ending risks for most operational spacecraft, however, come from impacts with debris just above the threshold of the protection shields (5-mm to 1-cm). A solution-driven approach is to seek: Concepts for removal of massive intacts with high P(collision); Concepts capable of preventing collisions involving intacts; Concepts for removal of 5-mm to 1-cm debris; Enhanced impact protection shields for valuable space assets. Key questions for remediation consideration of orbital debris: What is the acceptable threat level? What are the mission objectives? What is the appropriate roadmap/timeframe for remediation? Support advanced technology development when an economically viable approach is identified. Address non-technical issues, such as policy, coordination, ownership, legal, and liability at the national and international levels.

One of the main reasons against organ donation is the fear of apparent death due to ignorance of the brain death concept. Our aim was to assess knowledge about and acceptance of the brain death concept among the population of Havana, Cuba. The population screened, stratified by gender and age, included those >15 years old and living in Havana, Cuba. The appraisal tool utilized was a questionnaire on attitude toward organ donation ("PCID-DTO Ríos"). A random selection of individuals were surveyed according to the stratification. Cuba's census data were used. The participation was anonymized and self-administered. The verbal consent of participants was provided. There were 920 respondents: 31% (n = 282) knew the concept of brain death and accepted it; 57% (n = 529) did not; and 12% (n = 109) had a misperception, or did not accept brain death as a person's death. Those who knew and accepted the concept had a more favorable attitude toward their own organ donation after death (85% vs 61%; P < .001). The psychosocial factors related to the knowledge of brain death concept were: the gender (P = .002), to make up for speaking at a family level about the organ transplant (P < .001), the couple's opinion about the organ donation (P < .001) and the religion (P < .001). The brain death concept is not well understood in the population of Havana, Cuba. Copyright © 2017 Elsevier Inc. All rights reserved.

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

PubMed

Roman-Liu, Danuta

2014-05-01

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

Helicobacter pylori Detection and Antimicrobial Susceptibility Testing

PubMed Central

Mégraud, Francis; Lehours, Philippe

2007-01-01

The discovery of Helicobacter pylori in 1982 was the starting point of a revolution concerning the concepts and management of gastroduodenal diseases. It is now well accepted that the most common stomach disease, peptic ulcer disease, is an infectious disease, and all consensus conferences agree that the causative agent, H. pylori, must be treated with antibiotics. Furthermore, the concept emerged that this bacterium could be the trigger of various malignant diseases of the stomach, and it is now a model for chronic bacterial infections causing cancer. Most of the many different techniques involved in diagnosis of H. pylori infection are performed in clinical microbiology laboratories. The aim of this article is to review the current status of these methods and their application, highlighting the important progress which has been made in the past decade. Both invasive and noninvasive techniques will be reviewed. PMID:17428887

Review paper: Organ transplants: ethical, social, and religious issues in a multicultural society.

2010-07-01

Recent advances in the fields of organ donation and organ transplant have introduced new hope for the treatment of serious diseases. However, this promise has been accompanied by several issues. The most common issue raised is ethical implications, but in a multicultural society like Malaysia, additional concerns arise pertaining to social and religious issues. These concerns needs to be addressed as attitudes toward and acceptability of organ donation varies according to social, culture, and religion. The diverse cultural, religious, and traditional concepts pertaining to organ donation may hamper its acceptability and cause a lack of willingness to donate organs. The purpose of this article is to briefly explore the ethical issues involved in organ transplant and the various religious opinions on organ donation. It is hoped that this knowledge and understanding may benefit both health care providers and patients in a multicultural society like Malaysia.

Background Providing high-quality clinical cases is important for teaching radiology. We developed, implemented and evaluated a program for a university hospital to support this task. Methods The system was built with Intranet technology and connected to the Picture Archiving and Communications System (PACS). It contains cases for every user group from students to attendants and is structured according to the ACR-code (American College of Radiology) [2]. Each department member was given an individual account, could gather his teaching cases and put the completed cases into the common database. Results During 18 months 583 cases containing 4136 images involving all radiological techniques were compiled and 350 cases put into the common case repository. Workflow integration as well as individual interest influenced the personal efforts to participate but an increasing number of cases and minor modifications of the program improved user acceptance continuously. 101 students went through an evaluation which showed a high level of acceptance and a special interest in elaborate documentation. Conclusion Electronic access to reference cases for all department members anytime anywhere is feasible. Critical success factors are workflow integration, reliability, efficient retrieval strategies and incentives for case authoring. PMID:11686856

2009-01-01

Background In many rural regions in Germany, the proportion of the elderly population increases rapidly. Simultaneously, about one-third of the presently active GPs will retire until 2010. Often it is difficult to find successors for vacant GP-practices. These regions require innovative concepts to avoid the imminent shortage in primary health care. The AGnES-concept comprises the delegation of GP-home visits to qualified AGnES-practice assistants (AGnES: GP-supporting, community-based, e-health-assisted, systemic intervention). Main objectives were the assessment of the acceptance of the AGnES-concept by the participating GPs, patients, and AGnES-practice assistants, the kind of delegated tasks, and the feasibility of home telecare in a GP-practice. Methods In this paper, we report first results of the implementation of this concept in regular GP-practices, conducted November 2005 – March 2007 on the Island of Rügen, Mecklenburg-Western Pomerania, Germany. This study was meant as a proof of concept. The GP delegated routine home-visits to qualified practice employees (here: registered nurses). Eligible patients were provided with telecare-devices to monitor disease-related physiological values. All delegated tasks, modules conducted and questionnaire responses were documented. The participating patients were asked for their acceptance based on standardized questionnaires. The GPs and AGnES-practice assistants were asked for their judgement about different project components, the quality of health care provision and the competences of the AGnES-practice assistants. Results 550 home visits were conducted. 105 patients, two GPs and three AGnES-practice assistants (all registered nurses) participated in the project. 48 patients used telecare-devices to monitor health parameters. 87.4% of the patients accepted AGnES-care as comparable to common GP-care. In the course of the project, the GPs delegated an increasing number of both monitoring and interventional tasks to the AGnES-practice assistants. The GPs agreed that delegating tasks to a qualified practice assistant relieves them in their daily work. Conclusion A part of the GPs home visits can be delegated to AGnES-practice assistants to support GPs in regions with an imminent or already existing undersupply in primary care. The project triggered discussions among the institutions involved in the German healthcare system and supported a reconciliation of the respective competences of physicians and other medical professions.

[Self-acceptance as adaptively resigning the self to low self-evaluation].

PubMed

Ueda, T

1996-10-01

In past studies, the concept of self-acceptance has often been confused with self-evaluation or self-esteem. The purpose of this study was to distinguish these concepts, and operationally define self-acceptance as Carl Rogers proposed: feeling all right toward the self when self-evaluation was low. Self-acceptance as adaptive resignation, a moderating variable, therefore should raise self-esteem of only those people with low self-evaluation. Self-acceptance was measured in the study as affirmative evaluation of own self-evaluation. Two hundred and forty college students, 120 each for men and women, completed a questionnaire of self-evaluative consciousness and self-esteem scales. Results of statistical analyses showed that among subjects with low self-evaluation, the higher self-acceptance, the higher the person's self-esteem. The same relation was not observed among those with high self-evaluation. Thus, it may be concluded that self-acceptance was adaptive resignation, and therefore meaningful to only those with low self-evaluation.

Acute ankle sprain in dancers.

PubMed

Russell, Jeffrey A

2010-01-01

Ankle sprain is a common injury in dancers. Because of the relative frequency of this injury and its wide acceptance as a likely part of an active lifestyle, in many individuals it may not receive the careful attention it deserves. An extreme ankle range of motion and excellent ankle stability are fundamental to success in dance. Hence, following a proper treatment protocol is crucial for allowing a dancer who suffers an ankle sprain to return to dance as soon as possible without impaired function. This article reviews the basic principles of the etiology and management of ankle sprain in dancers. Key concepts are on-site examination and treatment, early restoration, dance-specific rehabilitation, and a carefully administered safe return to dance. Additionally, injuries that may occur in conjunction with ankle sprain are highlighted, and practical, clinically relevant summary concepts for dance healthcare professionals, dance scientists, dance teachers, and dancers are provided.

An Overview of a Trajectory-Based Solution for En Route and Terminal Area Self-Spacing: Fifth Edition

NASA Technical Reports Server (NTRS)

Abbott, Terence S.

2015-01-01

This paper presents an overview of the fifth revision to an algorithm specifically designed to support NASA's Airborne Precision Spacing concept. This algorithm is referred to as the Airborne Spacing for Terminal Arrival Routes version 12 (ASTAR12). This airborne self-spacing concept is trajectory-based, allowing for spacing operations prior to the aircraft being on a common path. Because this algorithm is trajectory-based, it also has the inherent ability to support required-time-of- arrival (RTA) operations. This algorithm was also designed specifically to support a standalone, non-integrated implementation in the spacing aircraft. This current revision to the algorithm includes a ground speed feedback term to compensate for slower than expected traffic aircraft speeds based on the accepted air traffic control tendency to slow aircraft below the nominal arrival speeds when they are farther from the airport.

Diagnosing Portuguese Students' Misconceptions about the Mineral Concept

Monteiro, António; Nóbrega, Clévio; Abrantes, Isabel; Gomes, Celeste

2012-11-01

Educational researchers and teachers are well aware that misconceptions-erroneous ideas that differ from the scientifically accepted ones-are very common amongst students. Daily experiences, creative and perceptive thinking and science textbooks give rise to students' misconceptions which lead them to draw erroneous conclusions that become strongly attached to their views and somehow affect subsequent learning. The main scope of this study was to understand what students consider a mineral to be and why. Therefore, the goals were (1) to identify eleventh-grade students' misconceptions about the mineral concept; (2) to understand which variables (gender, parents' education level and attitude towards science) influenced students' conceptions; and (3) to create teaching tools for the prevention of misconceptions. In order to achieve these goals, a diagnostic instrument (DI), constituted of a two-tier diagnostic test and a Science Attitude Questionnaire, was developed to be used with a sample of 89 twelfth-grade students from five schools located in central Portugal. As far as we know, this is the first DI developed for the analysis of misconceptions about the mineral concept. Data analysis allows us to conclude that students had serious difficulties in understanding the mineral concept, having easily formed misconceptions. The variables gender and parents' education level influence certain students' conceptions. This study provides a valuable basis for reflection on teaching and learning strategies, especially on this particular theme.

Human Non-persons, Feticide, and the Erosion of Dignity

PubMed Central

2010-01-01

Feticide, the practice of terminating the life of an otherwise viable fetus in utero, has become an increasingly common practice in obstetric centres around the globe, a concomitant of antenatal screening technologies. This paper examines this expanding practice in light of the concept of human dignity. Although it is assumed from the outset that even viable human fetuses are not persons and as such do not enjoy full membership in the moral community, it is argued that the fact that these are nevertheless human fetuses affords them prima facie moral status. Thus even those who accept a liberal position with regard to therapeutic abortion, should be concerned about these more recent developments. Indeed, how we treat viable human fetuses has implications for our prospective treatment of other human non-persons and could undermine the common human dignity we all share. PMID:21212811

Relationships with mother, teacher, and peers: unique and joint effects on young children's self-concept.

Verschueren, Karine; Doumen, Sarah; Buyse, Evelien

2012-01-01

This study tested the unique and joint effects of three significant relationships in young children's social lives, namely their relationships with mother, teacher, and peers, on three dimensions of self-concept (general, academic, and social). A sample of 113 children participated. Mother-child attachment quality was observed in preschool. In first grade, teacher ratings of teacher-child relationship quality, peer ratings of peer acceptance, and child reports of self-concept were administered. The results revealed domain-specific links between social relationships and self-concept dimensions. Specifically, academic self-concept related to teacher-child relationship quality, social self-concept to peer acceptance, and general self-concept to the quality of attachment to mother. Moreover, an indirect effect was revealed of earlier mother-child attachment quality on the academic dimension of self through its effect on current adult-child relationships in school. This way, the study uncovered the pathways through which significant social relationships shape the formation of young children's self-concept.

A Disorder of Qi: Breathing Exercise as a Cure for Neurasthenia in Japan, 1900–1945

PubMed Central

Wu, Yu-Chuan

2016-01-01

Neurasthenia became a common disease and caused widespread concern in Japan at the turn of the twentieth century, whereas only a couple of decades earlier the term “nerve” had been unfamiliar, if not unknown, to many Japanese. By exploring the theories and practices of breathing exercise—one of the most popular treatments for neurasthenia at the time—this paper attempts to understand how people who practiced breathing exercises for their nervous ills perceived, conceived, and accordingly cared for their nerves. It argues that they understood “nerve” based on their existing conceptions of qi. Neurasthenia was for them a disorder of qi, although the qi had assumed modern appearances as blood and nervous current. The paper hopes to contribute to the understanding of how the concept of nerves has been accepted and assimilated in East Asia. It also points out the need to understand the varied cultures of nerves not only at the level of concept and metaphor, but also at the level of perception and experience. PMID:26363046

Understanding Students' Reasoning: Argumentation Schemes as an Interpretation Method in Science Education

NASA Astrophysics Data System (ADS)

Konstantinidou, Aikaterini; Macagno, Fabrizio

2013-05-01

The purpose of this paper is to investigate the argumentative structure of students' arguments using argumentation schemes as an instrument for reconstructing the missing premises underlying their reasoning. Building on the recent literature in science education, in order for an explanation to be persuasive and achieve a conceptual change it needs to proceed from the interlocutor's background knowledge to the analysis of the unknown or wrongly interpreted phenomena. Argumentation schemes represent the abstract forms of the most used and common forms of human reasoning, combining logical principles with semantic concepts. By identifying the argument structure it is possible to retrieve the missing premises and the crucial concepts and definition on which the conclusion is based. This method of analysis will be shown to provide the teacher with an instrument to improve his or her explanations by taking into consideration the students' intuitions and deep background knowledge on a specific issue. In this fashion the teacher can advance counterarguments or propose new perspectives on the subject matter in order to persuade the students to accept new scientific concepts.

Confusion of recovery: one solution.

PubMed

Collier, Elizabeth

2010-02-01

This paper questions the current mental health discourse that offers new definitions of the concept of 'recovery' and offers a different perspective that aims to clarify its meaning. Confusion is caused when medical language continues to be used in discussions that aim to challenge traditional medical understanding of the term 'recovery' (meaning cure). Medical and non-medical concepts of recovery are referred to interchangeably in many narratives and the common references to and acceptance of the Harding et al. papers and similar that report on how people can 'get better' from schizophrenia perpetuates this confusion. In this paper, it is suggested that 'recovery' should not be viewed as having new meaning, but that two different concepts have been confused, with the same word having been used to describe two completely different things altogether. This means that what is referred to in this paper as 'medical' recovery (traditional definitions of recovery that aims for cure), becomes subordinate to 'life' recovery (personal development and change) in which psychiatric classification might have no part in a person's understanding of their experience and where improving 'symptoms' could be irrelevant in the personal process of growth and discovery.

Puljak, Livia; Sapunar, Damir

2017-12-12

Systematic reviews (SRs) have been proposed as a type of research methodology that should be acceptable for a graduate research thesis. The aim of this study was to analyse whether PhD theses in European biomedical graduate programs can be partly or entirely based on SRs. In 2016, we surveyed individuals in charge of European PhD programs from 105 institutions. The survey asked about acceptance of SRs as the partial or entire basis for a PhD thesis, their attitude towards such a model for PhD theses, and their knowledge about SR methodology. We received responses from 86 individuals running PhD programs in 68 institutions (institutional response rate of 65%). In 47% of the programs, SRs were an acceptable study design for a PhD thesis. However, only 20% of participants expressed a personal opinion that SRs meet the criteria for a PhD thesis. The most common reasons for not accepting SRs as the basis for PhD theses were that SRs are 'not a result of a PhD candidate's independent work, but more of a team effort' and that SRs 'do not produce enough new knowledge for a dissertation'. The majority of participants were not familiar with basic concepts related to SRs; questions about meta-analyses and the type of plots frequently used in SRs were correctly answered by only one third of the participants. Raising awareness about the importance of SRs and their methodology could contribute to higher acceptance of SRs as a type of research that forms the basis of a PhD thesis.

Parenting Stress, Perceived Parenting Behaviors, and Adolescent Self-Concept in European American Families

2008-01-01

This study assesses whether the stresses associated with parenting a child are indirectly related to adolescent self-concept through parenting behaviors. We examined longitudinal associations among mothers’ and fathers’ parenting stress at age 10, children’s perceptions of parenting at age 10, and adolescents’ self-concept at age 14 in 120 European American families. Mothers’ and fathers’ parenting stress was related to children’s perceptions of acceptance and psychologically controlling behavior, and psychologically controlling behavior (and lax control for fathers) was related to adolescent self-concept. We further examined which domains of parenting stress and perceived parenting behaviors were associated with adolescents’ scholastic competence, social acceptance, physical appearance, and behavioral conduct. Parenting stress was related to specific parenting behaviors, which were, in turn, related to specific domains of self-concept in adolescence. Parenting stress appears to exert its effects on early adolescent self-concept indirectly through perceived parenting behavior. PMID:18855511

2011-08-26

HIV/AIDS has always been one of the most thoroughly global of diseases. In the era of widely available anti-retroviral therapy (ART), it is also commonly recognised as a chronic disease that can be successfully managed on a long-term basis. This article examines the chronic character of the HIV/AIDS pandemic and highlights some of the changes we might expect to see at the global level as HIV is increasingly normalised as "just another chronic disease". The article also addresses the use of this language of chronicity to interpret the HIV/AIDS pandemic and calls into question some of the consequences of an uncritical acceptance of concepts of chronicity.

TASAR Flight Trial 2: Assessment of Air Traffic Controller Acceptability of TASAR Requests

NASA Technical Reports Server (NTRS)

Idris, Husni; Enea, Gabriele

2016-01-01

In support of the Flight Trial (FT-2) of NASA's prototype of the Traffic Aware Strategic Aircrew Requests (TASAR) concept, observations were conducted at the air traffic facilities to identify and assess the main factors that affect the acceptability of pilot requests by air traffic controllers. Two observers shadowed air traffic controllers at the Atlanta (ZTL) and Jacksonville (ZJX) air traffic control centers as the test flight pilot made pre-scripted requests to invoke acceptability issues and then they interviewed the observed and other controllers voluntarily. Fifty controllers were interviewed with experience ranging from one to thirty-five years. All interviewed controllers were enthusiastic about the technology and accounting for sector boundaries in pilot requests, particularly if pilots can be made aware of high workload situations. All interviewed controllers accept more than fifty percent of pilot requests; forty percent of them reject less than ten percent of requests. The most common reason for rejecting requests is conflicting with traffic followed by violating letters of agreement (LOAs) and negatively impacting neighboring sector workload, major arrival and departure flows and flow restrictions. Thirty-six requests were made during the test, eight of which were rejected due to: the aircraft already handed off to another sector, violating LOA, opposing traffic, intruding into an active special use airspace (SUA), intruding into another center, weather, and unfamiliarity with the requested waypoint. Nine requests were accepted with delay mostly because the controller needed to locate unfamiliar waypoints or to coordinate with other controllers.

Validation in Support of Internationally Harmonised OECD Test Guidelines for Assessing the Safety of Chemicals.

PubMed

Gourmelon, Anne; Delrue, Nathalie

Ten years elapsed since the OECD published the Guidance document on the validation and international regulatory acceptance of test methods for hazard assessment. Much experience has been gained since then in validation centres, in countries and at the OECD on a variety of test methods that were subjected to validation studies. This chapter reviews validation principles and highlights common features that appear to be important for further regulatory acceptance across studies. Existing OECD-agreed validation principles will most likely generally remain relevant and applicable to address challenges associated with the validation of future test methods. Some adaptations may be needed to take into account the level of technique introduced in test systems, but demonstration of relevance and reliability will continue to play a central role as pre-requisite for the regulatory acceptance. Demonstration of relevance will become more challenging for test methods that form part of a set of predictive tools and methods, and that do not stand alone. OECD is keen on ensuring that while these concepts evolve, countries can continue to rely on valid methods and harmonised approaches for an efficient testing and assessment of chemicals.

2014-09-01

Palliative care is an emerging concept in the countries of the Gulf Cooperation Council, a political and economic union of Arab states bordering the Persian Gulf, namely Bahrain, Kuwait, Oman, Qatar, Saudi Arabia, and the United Arab Emirates. Clinical pharmacy services have not yet been evaluated in this region. The objectives of this study were to create a baseline inventory of clinical pharmacy interventions in palliative care and to assess the perceived importance of interventions made. This was a prospective, single-center characterization study. Interventions were documented from September 30 to December 1, 2013. They were characterized into predetermined categories and analyzed using descriptive statistics. Physician acceptance rate and intervention rate per patient were calculated. Classification categories were sent to 10 practicing pharmacists in each of Qatar and Canada, who ranked the categories on the basis of perceived importance. A total of 96 interventions were documented, giving 3 interventions per patient and an acceptance rate of 81%. Discontinuing therapy (29%), initiating therapy (25%), and provision of education/counseling (13.5%) were most common. No differences were found between rankings from pharmacists in Qatar or Canada. Clinical pharmacy interventions are frequent, and those relating to alterations in drug therapy are most common. Interventions align with the perceived importance from pharmacists in both Qatar and Canada.

Background: To date, prevention efforts of company medical officers and general practitioners are largely independent of each other. In a comprehensive model of healthcare management including both sets of doctors, the company doctor should determine the risk of cardiovascular disease in the employees of the company. In case increased risk is detected, there should be exchange of information between the 2 professional groups so that common preventive interventions can be decided upon. Aim: The aim of this pilot study was to determine how well cardiovascular risk assessment is accepted by employees of a midsize company and where prevention is needed. Materials and Methods: In a company with 660 employees, risk analysis was conducted among staff in the context of regular preventive measures. In addition to risk factors, primary care, agreement with an interdisciplinary exchange of information and motivation for health promotion activities were investigated. Results: 204 employees (4 females only) were examined. The average age of the participants was 42.9±10.3 years. In 27% (n=55), an increased overall risk was present. Employees with risk requiring medical intervention were under the care of primary care physician and most of them (70%) agreed to the transfer of information to these physicians. In the survey itself, employees showed sufficient motivation (VAS 6.4±2.8) for workplace health promotion. Conclusion: The examined company agreed to implementing further health promoting activities. Due to demographic changes, new concepts for effective prevention are needed. The high acceptance of the proposed prevention framework should motivate implementation of this concept. As a next step, studies must be conducted to examine the effectiveness of screening for risk carried out by company medical officers. © Georg Thieme Verlag KG Stuttgart · New York.

On the meaning and use of the risk appetite concept.

PubMed

Aven, Terje

2013-03-01

The risk appetite concept has been given considerable attention recently in enterprise risk management contexts. A number of definitions exist, most with a link to risk acceptability, but also values and goals. The usefulness of the concept is, however, disputed; some authors argue that we can in fact do better without it. In this article, we provide a thorough discussion of what the risk appetite concept is actually trying to express and how it best can be used in the relevant decision making. The main purposes of the article are (i) to argue that the risk appetite concept, suitably interpreted, has a role to play in risk management, (ii) to show that the risk appetite concept is well supported by some types of risk perspectives and not by others, and (iii) to show how the risk appetite concept is linked to other related concepts, such as risk seeking and risk acceptability. The risk perspectives studied range from expected value and probability based definitions of risk to views on risk, that are founded on uncertainties. © 2012 Society for Risk Analysis.

Telemetry systems enable researchers to continuously monitor physiological signals in unrestrained, freely moving small rodents. Drawbacks of common systems are limited operation time, the need to house the animals separately, and the necessity of a stable communication link. Furthermore, the costs of the typically proprietary telemetry systems reduce the acceptance. The aim of this paper is to introduce a low-cost telemetry system based on common radio frequency identification technology optimized for battery-independent operational time, good reusability, and flexibility. The presented implant is equipped with sensors to measure electrocardiogram, arterial blood pressure, and body temperature. The biological signals are transmitted as digital data streams. The device is able of monitoring several freely moving animals housed in groups with a single reader station. The modular concept of the system significantly reduces the costs to monitor multiple physiological functions and refining procedures in preclinical research.

Severe acquired anaemia in Africa: new concepts.

PubMed

van Hensbroek, Michael B; Jonker, Femkje; Bates, Imelda

2011-09-01

Severe anaemia is common in Africa. It has a high mortality and particularly affects young children and pregnant women. Recent research provides new insights into the mechanisms and causes of severe acquired anaemia and overturns accepted dogma. Deficiencies of vitamin B12 and vitamin A, but not of iron or folic acid, are associated with severe anaemia. Bacterial infections and, in very young children, hookworm infections are also common in severe anaemia. Irrespective of the aetiology, the mechanism causing severe anaemia is often red cell production failure. Severe anaemia in Africa is therefore a complex multi-factorial syndrome, which, even in an individual patient, is unlikely to be amenable to a single intervention. Policies and practices concerning anaemia diagnosis, treatment and prevention need to be substantially revised if we are to make a significant impact on the huge burden of severe anaemia in Africa. © 2011 Blackwell Publishing Ltd.

Guobis, Zygimantas; Baseviciene, Nomeda; Paipaliene, Pajauta; Sabalys, Gintautas; Kubilius, Ricardas

2006-01-01

The aim of this article is to review the problem of xerostomia considering its clinical, etiological, diagnostic and treatment features, basing on the today's tutorials and scientific articles found in databases on the Internet. Recent epidemiologic data on the prevalence of xerostomia in different countries are introduced. There are analyzed the main aspects of clinical manifestations of xerostomia, according to the different etiology analyzed. The most common etiological factors causing xerostomia, especially the main three of them: radiation therapy, Sjögren's syndrome, and drugs, are pointed out. The most popular and accepted clinical and laboratory assays for measuring and evaluating the function of salivary glands are represented. Attention is paid to xerostomia as substantiation of the separate diagnosis and its role in diagnosing other diseases. The concept of possible treatment modalities and prognosis are discussed. The main and most common problems concerning xerostomia are revealed.

Peer relations in adolescents: effects of parenting and adolescents' self-concept.

Deković, M; Meeus, W

1997-04-01

In this study we examined the link between the parent-adolescent relationship and the adolescent's relationship with peers. The proposed model assumes that the quality of the parent-child relationship affects the adolescent's self-concept, which in turn affects the adolescent's integration into the world of peers. The sample consisted of 508 families with adolescents (12- to 18-years-old). The data were obtained at the subjects' homes, where a battery of questionnaires was administered individually to mothers, fathers and adolescents. Several constructs relating to the quality of parent-child relationship were assessed: parental acceptance, attachment, involvement, responsiveness, love withdrawal and monitoring of the child. The measures of the adolescent's self-concept included Harter's Perceived Competence Scale for Adolescents and Rosenberg's Self-Esteem Scale. The indicators of the quality of peer relations were: degree of peer activity, having a best friend, perceived acceptance by peers and attachment to peers. Assessment of the hypothesized model showed that the adolescent's self-concept serves a mediating role in the relationship between maternal child-rearing style and involvement with peers. The mediating role of self-concept was greatest for maternal acceptance. Paternal child-rearing style, however, appeared to have an independent effect on the adolescent's involvement with peers that is not accounted for by the adolescent's self-concept. The prediction of the quality of adolescents' peer relations yielded similar results for both mothers and fathers. The results suggest that a positive self-concept and warm supportive parenting each contribute unique variance to satisfactory peer relations.

Expanding the FCI to Eevaluate Conceptual Mastery of Energy, Momentum, and Rotational Dynamics

NASA Astrophysics Data System (ADS)

Chediak, Alex; Hay, Katrina

2010-03-01

Normalized gain on the Force Concept Inventory (FCI) has deservedly become a widely accepted assessment tool to evaluate conceptual mastery in a high school, college, or university-level mechanics course. Left out of this assessment, however, are important physics concepts typically presented in the same course. Conservation of energy and momentum as well as rotational motion receive scant (if any) coverage on the FCI (or, for that matter, the Mechanics Baseline Test). Yet these concepts are foundational for popular majors such as mechanical engineering, where high failure rates are often a concern. A revised assessment tool is presented, one that incorporates the strengths of the FCI (and preserves the straightforward multiple choice format), but assesses these other mechanics-related concepts. Ten additional questions are included, inspired in part by material from the Physics Education Group at the University of Washington and in part by the authors' own experiences with common student misperceptions. The questions are given as pre- and post tests at the authors' institutions, California Baptist University and Pacific Lutheran University, in both calculus-based and algebra-based mechanics courses, exploring breadth of applicability for our findings. We present normalized gain data for the traditional thirty FCI questions and for our ten additional questions.

Intentional learning: A concept analysis.

PubMed

Mollman, Sarah; Candela, Lori

2018-01-01

To use a concept analysis to determine a clear definition of the term "intentional learning" for use in nursing. The term intentional learning has been used for years in educational, business, and even nursing literature. It has been used to denote processes leading to higher order thinking and the ability to use knowledge in new situations; both of which are important skills to develop in nursing students. But the lack of a common, accepted definition of the term makes it difficult for nurse educators to base instruction and learning experiences on or to evaluate its overall effectiveness in educating students for diverse, fast-paced clinical practices. A concept analysis following the eight-step method developed by Walker and Avant (2011). Empirical and descriptive literature.  Five defining attributes were identified: (1) self-efficacy for learning, (2) active, effortful, and engaged learning, (3) mastery of goals where learning is the goal, (4) self-directed learning, and (5) self-regulation of learning. Through this concept analysis, nursing will have a clear definition of intentional learning. This will enable nurse educators to generate, evaluate, and test learning experiences that promote further development of intentional learning in nursing students. Nurses in practice will also be able to evaluate if the stated benefits are demonstrated and how this impacts patient care and outcomes. © 2017 Wiley Periodicals, Inc.

Acceptability of Health Care-Related Risks: A Literature Review.

PubMed

Quintard, Bruno; Roberts, Tamara; Nitaro, Léa; Quenon, Jean-Luc; Michel, Philippe

2016-03-01

Risk management aims at reducing risks associated with hospital care to an acceptable level, both in their frequency and their impact on health. The social acceptability of risk on the part of the general population and of the health-care professionals, faced with regular information about adverse events, is undoubtedly evolving rapidly.In contrast to risk acceptability, the concept of risk perception is of limited interest to risk managers because it does not inform on the behaviors and actions resulting from these perceptions. The aim of this work was to define the concept of social acceptability of risk through an in-depth examination of a wide-ranging and multidisciplinary literature. A 1990-2010 English and French literature review was carried out in medical, epidemiological, and human and social sciences online databases, gray literature, and books. Of the 5931 references retrieved, 203 met the inclusion criteria. We identified contributions from 5 major research fields: economic, sociocognitive, psychometric, sociological/anthropological, and interactionist. When assessing risks, individuals use a variety of psychological and social processes that include their perception not only of a given risk but also of their own personal and social resources. This global perception has a direct impact on the responses and actual behavior of individuals and groups, enabling them to cope with the risk and/or manage it. Social acceptability includes perceptions related to risks and the stated intentions of individual behavior. This concept may therefore be relevant for defining local and national patient safety priorities.

Evaluation of an Airborne Spacing Concept to Support Continuous Descent Arrival Operations

NASA Technical Reports Server (NTRS)

Murdoch, Jennifer L.; Barmore, Bryan E.; Baxley, Brian T.; Capron, William R.; Abbott, Terence S.

2009-01-01

This paper describes a human-in-the-loop experiment of an airborne spacing concept designed to support Continuous Descent Arrival (CDA) operations. The use of CDAs with traditional air traffic control (ATC) techniques may actually reduce an airport's arrival throughput since ATC must provide more airspace around aircraft on CDAs due to the variances in the aircraft trajectories. The intent of airborne self-spacing, where ATC delegates the speed control to the aircraft, is to maintain or even enhance an airport s landing rate during CDA operations by precisely achieving the desired time interval between aircraft at the runway threshold. This paper describes the operational concept along with the supporting airborne spacing tool and the results of a piloted evaluation of this concept, with the focus of the evaluation on pilot acceptability of the concept during off-nominal events. The results of this evaluation show a pilot acceptance of this airborne spacing concept with little negative performance impact over conventional CDAs.

A photovolataic power system with a battery storage capability is analyzed. A dual battery current control concept is proposed, which enables the battery to either supply or accept power depending upon system environment and load conditions. A simulation of the power system, including the battery current control, is developed and evaluated. The evaulation demonstrate the visbility of the battery control concept of switch the battery from a charge to discharge mode and back as required by load and environmental conditions. An acceptable system operation is demonstrated over the entire insolation range. Additionally, system sensitivity, bandwidth, and damping characteristics of the battery control are shown to be acceptable for a projected hardware implementation.

2009-01-01

This article examines changing common knowledge of elementary school children to scientific knowledge related to the relationship between water characteristics and the transmission of schistosomiasis through health education. A review of the literature and two case studies from rural elementary schools in Brazil show how the prevailing concept of dirty and polluted water, which has operated as an epistemological obstacle for acquiring scientific knowledge, may be related to symbolic thought and cultural parameters. Through an educational intervention not commonly applied to health programs involving elementary school students in two schistosomiasis-endemic rural communities in Brazil this paper describes the difficulties researchers encountered in changing the prevailing perception that very dirty and polluted water provides optimal conditions for schistosome transmission, to the scientifically accepted view that transmission occurs most often in visually clean, although fecally contaminated water. This conceptual difficulty may be largely explained in terms of the symbolism involved in clean and dirty water and the life-giving quality of water. Based on our results, we recommend that knowledge about water-related beliefs and concepts among school children should be considered in school-based health education programs in areas of endemic schistosomiasis and possibly other intestinal infections.

20 new items were developed to measure six concepts of family strengths and were administered, along with the Kansas Marital Satisfaction Scale, to over 266 married subjects as part of a larger survey of current and former members of the Christian Church (Disciples of Christ). A common factor analysis suggested that most of the items were associated with their expected factors, while reliability analyses indicated that most of the scales had acceptable estimates of internal consistency. The marital satisfaction items clearly were associated with their own factor and not other factors, providing support for the unidimensional nature of the Kansas Marital Satisfaction Scale and for its construct validity.

Automated Extraction of Secondary Flow Features

Dorney, Suzanne M.; Haimes, Robert

2005-01-01

The use of Computational Fluid Dynamics (CFD) has become standard practice in the design and development of the major components used for air and space propulsion. To aid in the post-processing and analysis phase of CFD many researchers now use automated feature extraction utilities. These tools can be used to detect the existence of such features as shocks, vortex cores and separation and re-attachment lines. The existence of secondary flow is another feature of significant importance to CFD engineers. Although the concept of secondary flow is relatively understood there is no commonly accepted mathematical definition for secondary flow. This paper will present a definition for secondary flow and one approach for automatically detecting and visualizing secondary flow.

The complexity comes when one attempts to measure and calculate this inherent ability, called the Natural Attenuation Capacity (NAC), and determine if it is sufficient to cleanse the system to agreed upon criteria.

Mass balance is a robust framework upon which all decisions can be made. The inflows to and outflows from the system are balanced against the NAC ofmore » the subsurface system. For MNA to be acceptable, the NAC is balanced against the contaminant loading to the subsurface system with the resulting outflow from the system being in a range that is acceptable to the regulating and decision-making parties.

Associations between dairy cow inter-service interval and probability of conception.

2018-07-01

Recent research has indicated that the interval between inseminations in modern dairy cattle is often longer than the commonly accepted cycle length of 18-24 days. This study analysed 257,396 inseminations in 75,745 cows from 312 herds in England and Wales. The interval between subsequent inseminations in the same cow in the same lactation (inter-service interval, ISI) were calculated and inseminations categorised as successful or unsuccessful depending on whether there was a corresponding calving event. Conception risk was calculated for each individual ISI between 16 and 28 days. A random effects logistic regression model was fitted to the data with pregnancy as the outcome variable and ISI (in days) included in the model as a categorical variable. The modal ISI was 22 days and the peak conception risk was 44% for ISIs of 21 days rising from 27% at 16 days. The logistic regression model revealed significant associations of conception risk with ISI as well as 305 day milk yield, insemination number, parity and days in milk. Predicted conception risk was lower for ISIs of 16, 17 and 18 days and higher for ISIs of 20, 21 and 22 days compared to 25 day ISIs. A mixture model was specified to identify clusters in insemination frequency and conception risk for ISIs between 3 and 50 days. A "high conception risk, high insemination frequency" cluster was identified between 19 and 26 days which indicated that this time period was the true latent distribution for ISI with optimal reproductive outcome. These findings suggest that the period of increased numbers of inseminations around 22 days identified in existing work coincides with the period of increased probability of conception and therefore likely represents true return estrus events.

The meaning of "independence" for older people in different residential settings.

PubMed

Hillcoat-Nallétamby, Sarah

2014-05-01

Drawing on older people's understandings of "independence" and Collopy's work on autonomy, the article elaborates an interpretive framework of the concept in relation to 3 residential settings-the private dwelling-home, the extra-care, and the residential-care settings. Data include 91 qualitative interviews with frail, older people living in each setting, collected as part of a larger Welsh study. Thematic analysis techniques were employed to identify patterns in meanings of independence across settings and then interpreted using Collopy's conceptualizations of autonomy, as well as notions of space and interdependencies. Independence has multiple meanings for older people, but certain meanings are common to all settings: Accepting help at hand; doing things alone; having family, friends, and money as resources; and preserving physical and mental capacities. Concepts of delegated, executional, authentic, decisional, and consumer autonomy, as well as social interdependencies and spatial and social independence, do provide appropriate higher order interpretive constructs of these meanings across settings. A broader interpretive framework of "independence" should encompass concepts of relative independence, autonomy(ies), as well as spatial and social independence, and can provide more nuanced interpretations of structured dependency and institutionalization theories when applied to different residential settings.

Health counseling before marriage can be a most worthwhile and satisfying aspect of preventive medicine. It is important in genetic diagnosis and the prevention of hereditary, sexually transmitted and other infectious diseases. To determine the acceptance of the concept of Premarital Health Counseling (PMHC), and to identify some factors, which may efect this acceptance among Saudis who attend Primary Health Care Center in Riyadh, Kingdom of Saudi Arabia (KSA), 1417H. The present study is a cross-sectional one with a selected sample of Saudis who attended the Primary Health Care Centers in Riyadh during the year 1417H. A multistage sampling and equal allocation stratified sampling within was used to select 484 persons comprising an equal number of males and females, married and single above the age of 18 years. A pre-designed pre-tested questionnaire sheet was used to collect the required data, which were then tabulated and statistically analyzed. The study indicated that 364 (75.2%) of the study population accepted the concept of Premarital Health Counseling. PMHC was positively affected by the advancing age, experience of marriage, educational level and well-understood Islamic-health related issues. Out f those who accepted the concept, 273 (75%) agreed on the exchange of PMHC certificates between couples to be married and 152 (42%) agreed on the implementation of legislation on PMHC. Also, 298 (82%) of them wanted PMHC to be confidential and 168 (46%) agreed to the concept despite its cost. As regards the location of PMHC, most of participants who agreed to PMHC would prefer it to be given at governmental establishments. The study recommended the implementation of PMHC in Saudi Arabia, since it was accepted by the study population. However, further studies should be carried out to determine the details to be incorporated in the PMHC, their implementation and legislation on demographic basis of the Saudi community. Also, a community health education program for PMHC has to be devised in collaboration with Islamic leaders.

Acceptance Probability (P a) Analysis for Process Validation Lifecycle Stages.

This paper introduces an innovative statistical approach towards understanding how variation impacts the acceptance criteria of quality attributes. Because of more complex stage-wise acceptance criteria, traditional process capability measures are inadequate for general application in the pharmaceutical industry. The probability of acceptance concept provides a clear measure, derived from specific acceptance criteria for each quality attribute. In line with the 2011 FDA Guidance, this approach systematically evaluates data and scientifically establishes evidence that a process is capable of consistently delivering quality product. The probability of acceptance provides a direct and readily understandable indication of product risk. As with traditional capability indices, the acceptance probability approach assumes that underlying data distributions are normal. The computational solutions for dosage uniformity and dissolution acceptance criteria are readily applicable. For dosage uniformity, the expected AV range may be determined using the s lo and s hi values along with the worst case estimates of the mean. This approach permits a risk-based assessment of future batch performance of the critical quality attributes. The concept is also readily applicable to sterile/non sterile liquid dose products. Quality attributes such as deliverable volume and assay per spray have stage-wise acceptance that can be converted into an acceptance probability. Accepted statistical guidelines indicate processes with C pk > 1.33 as performing well within statistical control and those with C pk < 1.0 as "incapable" (1). A C pk > 1.33 is associated with a centered process that will statistically produce less than 63 defective units per million. This is equivalent to an acceptance probability of >99.99%.

To assess the knowledge and beliefs on cervical cancer and HPV infection and to evaluate the acceptability of HPV vaccination among Chinese women. Seven focus groups were conducted with ethnic Chinese women aged 18-25 (n=20), 26-35 (n=13), and 36 and above (n=16) in a community women's health clinic in Hong Kong in 2006. The discussions were audio taped, transcribed and analyzed. Recurrent themes related to cervical cancer, HPV infection and vaccination were highlighted. Diverse conceptions on likely causes of cervical cancer were noted, covering biological, psychological, environmental, lifestyle and sexual factors. Most women had not heard of HPV and its mode of transmission. The participants had difficulties understanding and accepting the linkage between cervical cancer and the sexually transmitted HPV infection. HPV infection was seen as personally stigmatizing with significant adverse impact on self-esteem and significant relationships. Participants favored HPV vaccination both for themselves and their teenage daughters if authoritative endorsement was provided. Inadequate knowledge and misconceptions on cervical cancer and HPV were common. Most participants welcomed and favored having HPV vaccination. Apart from promoting HPV vaccination, cervical cancer prevention should also include strategies to promote knowledge and minimize the stigmatizing effect of a sexually transmitted HPV infection.

Assessment of Air Traffic Controller Acceptability of Aircrew Route Change Requests

NASA Technical Reports Server (NTRS)

Idris, Husni; Enea, Gabriele; Burke, Kelly; Wing, David

2017-01-01

NASA developed the traffic aware strategic aircrew requests concept for a cockpit automation that identifies route improvements and advises the aircrew to request the change from the air traffic controller. In order to increase the chance of air traffic control approval, the automation ensures that the route is clear of known traffic, weather, and airspace restrictions. Hence the technology is anticipated to provide benefits in areas such as flight efficiency, flight schedule compliance, passenger comfort, and pilot and controller workload. In support of a field trial of a prototype of the technology, observations were conducted at the Atlanta and Jacksonville air traffic control centers to identify the main factors that affect the acceptability of aircrew requests by air traffic controllers. Observers shadowed air traffic controllers as the test flight pilot made pre-scripted requests to invoke acceptability issues and then they interviewed voluntarily fifty controllers with experience ranging from one to thirty-five years. The most common reason for rejecting requests is conflicting with traffic followed by violating air traffic procedures, increasing sector workload, and conflicting with major arrival and departure flows and flow restrictions. Quantitative parameters such as the distance that a route should maintain from sector boundaries and special use airspace were identified and recommended for inclusion in the automation.

Problem-oriented patient record model as a conceptual foundation for a multi-professional electronic patient record.

PubMed

De Clercq, Etienne

2008-09-01

It is widely accepted that the development of electronic patient records, or even of a common electronic patient record, is one possible way to improve cooperation and data communication between nurses and physicians. Yet, little has been done so far to develop a common conceptual model for both medical and nursing patient records, which is a first challenge that should be met to set up a common electronic patient record. In this paper, we describe a problem-oriented conceptual model and we show how it may suit both nursing and medical perspectives in a hospital setting. We started from existing nursing theory and from an initial model previously set up for primary care. In a hospital pilot site, a multi-disciplinary team refined this model using one large and complex clinical case (retrospective study) and nine ongoing cases (prospective study). An internal validation was performed through hospital-wide multi-professional interviews and through discussions around a graphical user interface prototype. To assess the consistency of the model, a computer engineer specified it. Finally, a Belgian expert working group performed an external assessment of the model. As a basis for a common patient record we propose a simple problem-oriented conceptual model with two levels of meta-information. The model is mapped with current nursing theories and it includes the following concepts: "health care element", "health approach", "health agent", "contact", "subcontact" and "service". These concepts, their interrelationships and some practical rules for using the model are illustrated in this paper. Our results are compatible with ongoing standardization work at the Belgian and European levels. Our conceptual model is potentially a foundation for a multi-professional electronic patient record that is problem-oriented and therefore patient-centred.

Background As preventing cancer with the help of a vaccine is a comparatively new concept, awareness and education about it will have important implication in the implementation of this strategy. Materials and Methods Present explorative questionnaire based survey included 618 MBBS students for final analysis. Results Majority of participants (89.6%) were well aware of the preventable nature of cervical cancer. Most of them (89.2%) knew that necessary factor responsible for cervical cancer is infection with high risk HPV. Awareness regarding the availability of vaccine against cervical cancer was 75.6%. Females had a better awareness regarding availability of vaccine, target population for vaccination and about the catch up program. Overall acceptance of HPV vaccine among the population studied was 67.8%. Medical teaching had a definitive impact on the understanding of this important public health issue. Females seemed to be more ready to accept the vaccine and recommend it to others. For our study population the most common source of information was medical school teaching. Majority of participants agreed that the most important obstacle in implementation of HPV vaccination program in our country is inadequate information and 86.2% wanted to be educated by experts in this regard. Conclusion HPV vaccine for primary prevention of cervical cancer is a relatively new concept. Health professional will be able to play a pivotal role in popularizing this strategy. PMID:22859950

Many HIV serodiscordant couples have a strong desire to have their own biological children. Natural conception may be the only choice in some resource limited settings but data about natural conception is limited. Here, we reported our findings of natural conception in HIV serodiscordant couples. Between January 2008 and June 2014, we retrospectively collected data on 91 HIV serodiscordant couples presenting to Beijing Youan Hospital with childbearing desires. HIV counseling, effective ART on HIV infected partners, pre-exposure prophylaxis (PrEP) and post-exposure prophylaxis (PEP) in negative female partners and timed intercourse were used to maximally reduce the risk of HIV transmission. Of the 91 HIV serodiscordant couples, 43 were positive in male partners and 48 were positive in female partners. There were 196 unprotected vaginal intercourses, 100 natural conception and 97 newborns. There were no cases of HIV seroconversion in uninfected sexual partners. Natural conception may be an acceptable option in HIV-serodiscordant couples in resource limited settings if HIV-positive individuals have undetectable viremia on HAART, combined with HIV counseling, PrEP, PEP and timed intercourse.

Reference dose (RfD): description and use in health risk assessments

1988-12-01

For many years the concept of the acceptable daily intake has served the toxicological and regulatory fields quite well. However, as approaches to assessing the health significance of exposures to noncarcinogenic substances receive greater scrutiny, some difficulties with this traditional approach have become more apparent. Consequently, the concept of the reference dose is introduced in order to avoid use of prejudicial terms (e.g., safety and acceptable), to promote greater consistency in the assessment of noncarcinogenic chemicals, and to maintain the functional separation between risk assessment and risk management.

“I may not say we really have a method, it is gambling work”: Knowledge and acceptability of safer conception methods among providers and HIV clients in Uganda

In this qualitative study, researchers assessed knowledge, acceptability and feasibility of safer conception methods [SCM; timed unprotected intercourse (TUI), manual self-insemination, and sperm washing] among various healthcare providers (n=33) and 48 HIV clients with recent or current childbearing intentions in Uganda. While several clients and providers had heard of SCM, (especially TUI); few fully understood how to use the methods. All provider types expressed a desire to incorporate SCM into their practice; however, this will require training and counseling protocols, sensitization to overcome cultural norms that pose obstacles to these methods, and partner engagement (particularly men) in safer conception counseling.

Feedback is considered a key didactic element in medical education, especially for teaching of communication skills. This study investigates the impact of a best evidence-based practice feedback concept within the context of communication skills training (CST). We evaluate this concept for acceptance and changes in students self-ratings of communication competence. Our CST integrating feedback process comprises a short theoretical introduction presenting standards for good communication and a constructive 360° feedback from three perspectives: feedback from peers, from standardized patients (SPs), and from a trainer. Feed-forward process was facilitated for documenting suggestions for improvements based on observable behaviors to maximize learning benefits. Our CST was applied to four groups of eight or nine students. We assessed the data on students' acceptance using a 6-point scale ranging from very good (1) to poor (6), applied a forced choice question to rank didactic items, and assessed changes in student' self-ratings of their communication competence on a 10-cm visual analogue scale (VAS). Thirty-four medical undergraduates (82 % female, 18 % male) in their first clinical year, with an average age of 21.4 years (SD = 1.0), participated in the new training. The concept achieved high acceptance from good to very good: overall impression (M = 1.56), sufficient interaction for discussion (M = 1.15), and constructive learning atmosphere (M = 1.18). Specific elements, such as practical training with SPs (M = 1.18) and feedback by SPs (M = 1.12), showed highest acceptance. The forced choice ranking placed all feedback elements at the top of the list (feedback (FB) by SPs, rank 2; FB by trainer, rank 3; FB by colleagues, rank 4), whereas theoretical elements were at the bottom (theoretical introduction, rank 7; memory card, rank 9). Overall, student self-ratings of communication competence significantly improved in nine of the ten communication items assessed by VAS and showed a pre-post effect size of ES = 0.74 on a global rating. This study demonstrates that the training concept based on 360° behavioral feedback was well accepted and generated significant changes in student self-ratings of their communication competence. Further research is needed to determine the effects on objective communication performance.

The model of romantic love and the acceptance of related myths have been granted wide relevance in our context. It has also been suggested that the concept of love can play a role in the origin and maintenance of gender violence. As an initial step towards researching this relationship, the objective of this article is to study the prevailing concept of love in the Spanish population, as well as to analyze any differences that gender and age may introduce in this conception. A reduced version of the Love Attitudes Scale was administered to a representative sample of 1,351 people. Results show that both men and women widely accept the love styles Eros, Agape, Storge and Pragma, reject the Ludus style, and are indifferent to the Mania style. However, the order of preference for love styles is different for men and women and for different age groups. These results are analyzed and discussed.

Error, contradiction and reversal in science and medicine.

PubMed

Coccheri, Sergio

2017-06-01

Error and contradictions are not "per se" detrimental in science and medicine. Going back to the history of philosophy, Sir Francis Bacon stated that "truth emerges more readily from error than from confusion", and recently Popper introduced the concept of an approximate temporary truth that constitutes the engine of scientific progress. In biomedical research and in clinical practice we assisted during the last decades to many overturnings or reversals of concepts and practices. This phenomenon may discourage patients from accepting ordinary medical care and may favour the choice of alternative medicine. The media often enhance the disappointment for these discrepancies. In this note I recommend to transfer to patients the concept of a confirmed and dependable knowledge at the present time. However, physicians should tolerate uncertainty and accept the idea that medical concepts and applications are subjected to continuous progression, change and displacement.

Bartolini, Rosario M.; Winkler, Jennifer L.; Penny, Mary E.; LaMontagne, D. Scott

2012-01-01

Objective and Method Cervical cancer is the third most common cancer affecting women worldwide and it is an important cause of death, especially in developing countries. Cervical cancer is caused by human papillomavirus (HPV) and can be prevented by HPV vaccine. The challenge is to expand vaccine availability to countries where it is most needed. In 2008 Peru’s Ministry of Health implemented a demonstration project involving 5th grade girls in primary schools in the Piura region. We designed and conducted a qualitative study of the decision-making process among parents of girls, and developed a conceptual model describing the process of HPV vaccine acceptance. Results We found a nonlinear HPV decision-making process that evolved over time. Initially, the vaccine’s newness, the requirement of written consent, and provision of information were important. If information was sufficient and provided by credible sources, many parents accepted the vaccine. Later, after obtaining additional information from teachers, health personnel, and other trusted sources, more parents accepted vaccination. An understanding of the issues surrounding the vaccine developed, parents overcome fears and rumors, and engaged in family negotiations–including hearing the girl’s voice in the decision-making process. The concept of prevention (cancer as danger, future health, and trust in vaccines) combined with pragmatic factors (no cost, available at school) and the credibility of the offer (information in the media, recommendation of respected authority figure) were central to motivations that led parents to decide to vaccinate their daughters. A lack of confidence in the health system was the primary inhibitor of vaccine acceptance. Conclusions Health personnel and teachers are credible sources of information and can provide important support to HPV vaccination campaigns. PMID:23144719

Conjugal conflict and violence: a review and theoretical paradigm.

PubMed

Smilkstein, G; Aspy, C B; Quiggins, P A

1994-02-01

Conjugal violence has been described as having multiple etiologies. The variables are so numerous that intervention and research protocols are difficult to effect. This paper proposes a paradigm that establishes conjugal conflict and violence as separate entities. According to the paradigm, conjugal conflict is viewed as "an inevitable part of human association," whereas conjugal violence is determined to be a learned behavioral tactic that is employed as a coping strategy when an individual's conflict threshold potential is exceeded. Evidence will be offered that violence is learned from family of origin and from observing what is common or accepted practice in the community. Use of this paradigm would give primacy to community education programs that advance the concept of conflict resolution through rational discourse.

2014-10-01

The commonly accepted emblems of the Medical Profession are the staff of the Greek god of medicine--Asklepios (or Asclepius], on which one serpent is entwined. Later, around the 16th century C.E., the wand of the herald of the Greek Gods, e.g., Hermes, on which two snakes are entwined and facing each other, became popular as the emblem of the medical profession. We elaborate on the history of the evolution of these emblems as symbols of medicine, including earlier influences from the times of the ancient Egyptians and Babylonians, which were followed by Judeo-Christian traditions and concepts. The relevance of the use of the wand of Hermes as an emblem of our profession is further discussed.

Education for work: Reflections towards a theory of vocational education

NASA Astrophysics Data System (ADS)

Corson, David J.

1985-12-01

By integrating aspects of a philosophy of work and a sociology of work, this article draws conclusions relevant to framing a theory of vocational education. `Education for work' is accepted in this paper as the common central meaning of the term `vocational education'. The two concepts, `education' and `work', are first examined separately: `work' is seen to include recreational and occupational work, while occupational work is seen to fall on a continuum ranging from constrained to unconstrained occupational work. `Education' and `training' are distinguished. After a discussion of the conceptual links which might be drawn between `education' and `work', recommendations are made about the aims, the place, and the curriculum of vocational education within the general institution of education.

The Philosophical Basis of Bioethics.

PubMed

Horn, Peter

2015-09-01

In this article, I consider in what sense bioethics is philosophical. Philosophy includes both analysis and synthesis. Analysis focuses on central concepts in a domain, for example, informed consent, death, medical futility, and health. It is argued that analysis should avoid oversimplification. The synthesis or synoptic dimension prompts people to explain how their views have logical assumptions and implications. In addition to the conceptual elements are the evaluative and empirical dimensions. Among its functions, philosophy can be a form of prophylaxis--helping people avoid some commonly accepted questionable theories. Generally, recent philosophy has steered away from algorithms and deductivist approaches to ethical justification. In bioethics, philosophy works in partnership with a range of other disciplines, including pediatrics and neurology. Copyright © 2015 Elsevier Inc. All rights reserved.

Conceptualizing community: the experience of mental health consumers.

Wong, Yin-Ling Irene; Sands, Roberta G; Solomon, Phyllis L

2010-05-01

In this article we describe a focus group study of the perspectives of diverse groups of mental health consumers on the concept of community. We identify the core domains that constitute the notion of community, and commonalities and differences in the perception of community along the lines of ethnicity and sexual orientation/gender identity. Seven focus groups were conducted with a total of 62 participants. Transcripts were analyzed using the grounded theory approach.Two domains-togetherness and community acceptance-emerged as common to four types of communities that were most frequently mentioned in the focus group discussion. Our findings show that identities other than those associated with mental illness and the role of service user are critical to the understanding of the psychological sense of community among persons with psychiatric disabilities. We suggest that mental health providers empower consumers to expand their "personal communities" beyond that of mental health clients using their diverse identities, and design interventions for addressing the stigma emanating from identities that are discriminated against by the wider society.

The need for separate operational and engineering user interfaces for command and control of airborne synthetic aperture radar systems

NASA Astrophysics Data System (ADS)

Klein, Laura M.; McNamara, Laura A.

2017-05-01

In this paper, we address the needed components to create usable engineering and operational user interfaces (UIs) for airborne Synthetic Aperture Radar (SAR) systems. As airborne SAR technology gains wider acceptance in the remote sensing and Intelligence, Surveillance, and Reconnaissance (ISR) communities, the need for effective and appropriate UIs to command and control these sensors has also increased. However, despite the growing demand for SAR in operational environments, the technology still faces an adoption roadblock, in large part due to the lack of effective UIs. It is common to find operational interfaces that have barely grown beyond the disparate tools engineers and technologists developed to demonstrate an initial concept or system. While sensor usability and utility are common requirements to engineers and operators, their objectives for interacting with the sensor are different. As such, the amount and type of information presented ought to be tailored to the specific application.

Surgical timing of treating injured extremities: an evolving concept of urgency.

PubMed

Crist, Brett D; Ferguson, Tania; Murtha, Yvonne M; Lee, Mark A

2013-01-01

The management of some orthopaedic extremity injuries has changed over the past decade because of changing resource availability and the risks of complications. It is helpful to review the current literature regarding orthopaedic extremity emergencies and urgencies. The effects of the techniques of damage control orthopaedic techniques and the concept of the orthopaedic trauma room have also affected the management of these injuries. The available literature indicates that the remaining true orthopaedic extremity emergencies include compartment syndrome and vascular injuries associated with fractures and dislocations. Orthopaedic urgencies include open fracture management, femoral neck fractures in young patients treated with open reduction and internal fixation, and talus fractures that are open or those with impending skin compromise. Deciding when the definitive management of orthopaedic extremity injuries will occur has evolved as the concept of damage control orthopaedics has become more commonly accepted. Patient survival rates have improved with current resuscitative protocols. Definitive fixation of extremity injuries should be delayed until the patient's physiologic and extremity soft-tissue status allows for appropriate definitive management while minimizing the risks of complications. In patients with semiurgent orthopaedic injuries, the use of an orthopaedic trauma room has led to more efficient care of patients, fewer complications, and better time management for surgeons who perform on-call service for patients with traumatic orthopaedic injuries.

How do line managers experience and handle the return to work of employees on sick leave due to work-related stress? A one-year follow-up study.

2017-08-28

To examine how line managers experience and manage the return to work process of employees on sick leave due to work-related stress and to identify supportive and inhibiting factors. Semi-structured interviews with 15 line managers who have had employees on sick leave due to work-related stress. The grounded theory approach was employed. Even though managers may accept the overall concept of work-related stress, they focus on personality and individual circumstances when an employee is sick-listed due to work-related stress. The lack of a common understanding of stress creates room for this focus. Line managers experience cross-pressure, discrepancies between strategic and human-relationship perspectives and a lack of organizational support in the return to work process. Organizations should aim to provide support for line managers. Research-based knowledge and guidelines on work-related stress and return to work process are essential, as is the involvement of coworkers. A commonly accepted definition of stress and a systematic risk assessment is also important. Cross-pressure on line managers should be minimized and room for adequate preventive actions should be provided as such an approach could support both the return to work process and the implementation of important interventions in the work environment. Implication for rehabilitation Organizations should aim to provide support for line managers handling the return to work process. Cross-pressure on line managers should be minimized and adequate preventive actions should be provided in relation to the return to work process. Research-based knowledge and guidelines on work-related stress and return to work are essential. A common and formal definition of stress should be emphasized in the workplace.

2014-10-01

Numerous hospitals were combined years ago into a new Central Hospital for cost reasons in the Schwarzwald-Baar region. This also suggested the idea of a large central emergency department. The concept of a central emergency department is an organizational challenge, since they are directly engaged in the organizational structure of all medical departments that are involved in emergency treatment. Such a concept can only be enforced if it is supported by hospital management and all parties are willing to accept interdisciplinary and interprofessional work. In this paper, the concept of a central emergency department in a tertiary care hospital which was rebuilt as an organizationally independent unit is described. Collaborations with various departments, emergency services, and local physicians are highlighted. The processes of a central emergency department with an integrated admission department and personnel structures are described. The analysis of the concept after almost a year has shown that the integration into the clinic has been successful, the central emergency department has proven itself as a central hub and has been accepted as a unit within the hospital.

Acceptance and Commitment Therapy: Western adoption of Buddhist tenets?

PubMed

Fung, Kenneth

2015-08-01

Acceptance and Commitment Therapy (ACT) is a psychological intervention that has wide clinical applications with emerging empirical support. It is based on Functional Contextualism and is derived as a clinical application of the Relational Frame Theory, a behavioral account of the development of human thought and cognition. The six core ACT therapeutic processes include: Acceptance, Defusion, Present Moment, Self-as-Context, Values, and Committed Action. In addition to its explicit use of the concept of mindfulness, the therapeutic techniques of ACT implicitly incorporate other aspects of Buddhism. This article describes the basic principles and processes of ACT, explores the similarities and differences between ACT processes and some of the common tenets in Buddhism such as the Four Noble Truths and No-Self, and reports on the experience of running a pilot intervention ACT group for the Cambodian community in Toronto in partnership with the community's Buddhist Holy Monk. Based on this preliminary exploration in theory and the reflections of the group experience, ACT appears to be consistent with some of the core tenets of Buddhism in the approach towards alleviating suffering, with notable differences in scope reflecting their different aims and objectives. Further development of integrative therapies that can incorporate psychological and spiritual as well as diverse cultural perspectives may help the continued advancement and evolution of more effective psychotherapies that can benefit diverse populations. © The Author(s) 2014.

Practices and Perspectives of College Instructors on Addressing Religious Beliefs When Teaching Evolution.

2016-01-01

Evolution is a core concept of biology, and yet many college biology students do not accept evolution because of their religious beliefs. However, we do not currently know how instructors perceive their role in helping students accept evolution or how they address the perceived conflict between religion and evolution when they teach evolution. This study explores instructor practices and beliefs related to mitigating students' perceived conflict between religion and evolution. Interviews with 32 instructors revealed that many instructors do not believe it is their goal to help students accept evolution and that most instructors do not address the perceived conflict between religion and evolution. Instructors cited many barriers to discussing religion in the context of evolution in their classes, most notably the instructors' own personal beliefs that religion and evolution may be incompatible. These data are exploratory and are intended to stimulate a series of questions about how we as college biology instructors teach evolution. © 2016 M. E. Barnes and S. E. Brownell.

KEPLER Mission: development and overview

2016-03-01

The Kepler Mission is a space observatory launched in 2009 by NASA to monitor 170 000 stars over a period of four years to determine the frequency of Earth-size and larger planets in and near the habitable zone of Sun-like stars, the size and orbital distributions of these planets, and the types of stars they orbit. Kepler is the tenth in the series of NASA Discovery Program missions that are competitively-selected, PI-directed, medium-cost missions. The Mission concept and various instrument prototypes were developed at the Ames Research Center over a period of 18 years starting in 1983. The development of techniques to do the 10 ppm photometry required for Mission success took years of experimentation, several workshops, and the exploration of many ‘blind alleys’ before the construction of the flight instrument. Beginning in 1992 at the start of the NASA Discovery Program, the Kepler Mission concept was proposed five times before its acceptance for mission development in 2001. During that period, the concept evolved from a photometer in an L2 orbit that monitored 6000 stars in a 50 sq deg field-of-view (FOV) to one that was in a heliocentric orbit that simultaneously monitored 170 000 stars with a 105 sq deg FOV. Analysis of the data to date has detected over 4600 planetary candidates which include several hundred Earth-size planetary candidates, over a thousand confirmed planets, and Earth-size planets in the habitable zone (HZ). These discoveries provide the information required for estimates of the frequency of planets in our galaxy. The Mission results show that most stars have planets, many of these planets are similar in size to the Earth, and that systems with several planets are common. Although planets in the HZ are common, many are substantially larger than Earth.

Sphygmology is a 2000-year-old method that is still used in some traditional medicine systems, mainly Iranian, Chinese and Ayurveda. Ibn Sina is one of the most popular physicians in the history of Sphygmology, who had made great contributions to this method, but few meticulous studies have been made on his concepts. In this article, his standpoints on Pulsology are studied. Ibn Sina has mentioned 10 parameters for pulse palpation, and 13 compound pulses, as well. Besides, some pulse patterns applicable for differentiating similar diseases have been introduced. Nowadays some concepts on pulse patterns, such as pulse change in sleep and pregnancy have been studied; but unfortunately many of the ideas on Pulsology have not yet been examined. Sphygmology, as an accessible and inexpensive means, having a substantial diagnosis yield, has been accepted by the people since its rise, and its development over centuries ago. Although some new instruments have been innovated, which can measure different parameters of pulse, yet sphygmology can be one of the most commonly usable diagnostic methods in future, not only applicable by cardiologists but also by all the physicians.

Subject Matter Expert Evaluation of Multi-Flight Common Route Advisories

NASA Technical Reports Server (NTRS)

Bilimoria, Karl; Hayashi, Miwa; Sheth, Kapil S.

2017-01-01

Traffic flow management seeks to balance the demand for National Airspace System (NAS) flight resources, such as airspace and airports, with the available supply. When forecasted weather blocks nominal air traffic routes, traffic managers must re-route affected flights for weather avoidance. Depending on the nature and scope of the weather, traffic managers may use pre-coordinated re-routes such as Playbook Routes or Coded Departure Routes, or may design ad hoc local re-routes. The routes of affected flights are modified accordingly. These weather avoidance routes will, of course, be less efficient than the nominal routes due to increased flight time and fuel burn. In current traffic management operations, the transition into a weather avoidance re-routing initiative is typically implemented more aggressively than the transition out of that initiative after the weather has dissipated or moved away. For example, strategic large-scale Playbook re-routes are sometimes left in place (as initially implemented) for many hours before being lifted entirely when the weather dissipates. There is an opportunity to periodically modify the re-routing plan as weather evolves, thereby attenuating its adverse impact on flight time and fuel consumption; this is called delay recovery. Multi-Flight Common Routes (MFCR) is a NASA-developed operational concept and associated decision support tool for delay recovery, designed to assist traffic managers to efficiently update weather avoidance traffic routes after the original re-routes have become stale due to subsequent evolution of the convective weather system. MFCR groups multiple flights to reduce the number of advisories that the traffic manager needs to evaluate, and also merges these flights on a common route segment to provide an orderly flow of re-routed traffic. The advisory is presented to the appropriate traffic manager who evaluates it and has the option to modify it using MFCRs graphical user interface. If the traffic manager finds the advisory to be operationally appropriate, he or she would coordinate with the Area Supervisor(s) of the sectors that currently control the flights in the advisory. When the traffic manager accepts the MFCR advisory via the user interface, the corresponding flight plan amendments would be sent to the displays of the appropriate sector controllers, using the Airborne Re-Routing (ABRR) capability which is scheduled for nationwide operation in 2017. The sector controllers would then offer this time-saving route modification to the pilots of the affected flights via datalink (or voice), and implement the corresponding flight plan amendment if the pilots accept it. MFCR is implemented as an application in the software environment of the Future Air traffic management Concepts Evaluation Tool (FACET). This paper focuses on an initial subject matter expert (SME) evaluation of MFCR. The evaluation covers MFCRs operational concept, algorithm, and user interface.

Prolonged sitting time has been identified as a health risk factor. Sit-stand workstations allow desk workers to alternate between sitting and standing throughout the working day, but not much is known about their acceptability and feasibility. Hence, the aim of this study was to qualitatively evaluate the acceptability, feasibility and perceptions of using sit-stand workstations in a group of desk-based office workers. This article describes the qualitative evaluation of the randomized controlled cross-over Stand@Work pilot trial. Participants were adult employees recruited from a non-government health agency in Sydney, Australia. The intervention involved using an Ergotron Workfit S sit-stand workstation for four weeks. After the four week intervention, participants shared their perceptions and experiences of using the sit-stand workstation in focus group interviews with 4-5 participants. Topics covered in the focus groups included patterns of workstation use, barriers and facilitators to standing while working, effects on work performance, physical impacts, and feasibility in the office. Focus group field notes and transcripts were analysed in an iterative process during and after the data collection period to identify the main concepts and themes. During nine 45-min focus groups, a total of 42 participants were interviewed. Participants were largely intrinsically motivated to try the sit-stand workstation, mostly because of curiosity to try something new, interest in potential health benefits, and the relevance to the participant's own and organisation's work. Most participants used the sit-stand workstation and three common usage patterns were identified: task-based routine, time-based routine, and no particular routine. Common barriers to sit-stand workstation use were working in an open plan office, and issues with sit-stand workstation design. Common facilitators of sit-stand workstation use were a supportive work environment conducive to standing, perceived physical health benefits, and perceived work benefits. When prompted, most participants indicated they were interested in using a sit-stand workstation in the future. The use of a sit-stand workstation in this group of desk-based office workers was generally perceived as acceptable and feasible. Future studies are needed to explore this in different desk-based work populations and settings.

Structure and function in any organ are inseparable categories, both in health and disease. Whether we are ready to accept, or not, many questions in cardiovascular medicine are still pending, due to our insufficient insight in the basic science. Even so, any new concept encounters difficulties, mainly arising from our inert attitude, which may result either in unjustified acceptance or denial. The ventricular myocardial band concept, developed over the last 50 years, has revealed unavoidable coherence and mutual coupling of form and function in the ventricular myocardium. After more than five centuries long debate on macroscopic structure of the ventricular myocardium, this concept has provided a promising ground for its final understanding. Recent validations of the ventricular myocardial band, reviewed here, as well as future research directions that are pointed out, should initiate much wider scientific interest, which would, in turn, lead to reconciliation of some exceeded concepts about developmental, electrical, mechanical and energetical events in human heart. The benefit of this, of course, would be the most evident in the clinical arena.

A pilot study of yoga as self-care for arthritis in minority communities

PubMed Central

2013-01-01

Background While arthritis is the most common cause of disability, non-Hispanic blacks and Hispanics experience worse arthritis impact despite having the same or lower prevalence of arthritis compared to non-Hispanic whites. People with arthritis who exercise regularly have less pain, more energy, and improved sleep, yet arthritis is one of the most common reasons for limiting physical activity. Mind-body interventions, such as yoga, that teach stress management along with physical activity may be well suited for investigation in both osteoarthritis and rheumatoid arthritis. Yoga users are predominantly white, female, and college educated. There are few studies that examine yoga in minority populations; none address arthritis. This paper presents a study protocol examining the feasibility and acceptability of providing yoga to an urban, minority population with arthritis. Methods/design In this ongoing pilot study, a convenience sample of 20 minority adults diagnosed with either osteoarthritis or rheumatoid arthritis undergo an 8-week program of yoga classes. It is believed that by attending yoga classes designed for patients with arthritis, with racially concordant instructors; acceptability of yoga as an adjunct to standard arthritis treatment and self-care will be enhanced. Self-care is defined as adopting behaviors that improve physical and mental well-being. This concept is quantified through collecting patient-reported outcome measures related to spiritual growth, health responsibility, interpersonal relations, and stress management. Additional measures collected during this study include: physical function, anxiety/depression, fatigue, sleep disturbance, social roles, and pain; as well as baseline demographic and clinical data. Field notes, quantitative and qualitative data regarding feasibility and acceptability are also collected. Acceptability is determined by response/retention rates, positive qualitative data, and continuing yoga practice after three months. Discussion There are a number of challenges in recruiting and retaining participants from a community clinic serving minority populations. Adopting behaviors that improve well-being and quality of life include those that integrate mental health (mind) and physical health (body). Few studies have examined offering integrative modalities to this population. This pilot was undertaken to quantify measures of feasibility and acceptability that will be useful when evaluating future plans for expanding the study of yoga in urban, minority populations with arthritis.

[Resilience and Spirituality Considered from Viewpoint of Existential Philosophy of Karl Jaspers].

PubMed

Kato, Satoshi

2015-01-01

After publishing "General Psychopathology" in 1913, Jaspers turned his attention to serious philosophical contemplation. Using the term grenzsituation (limit situation) as a key concept, he first presented a framework to shed light on the pathology of both individuals and groups, and this led on to include the perspective of resilience. He then used three more key concepts, transzendenz (transcendence), chiffer (cipher), and unverstädliche (unintelligible) to offer a framework to focus on the possibilities of human existence. In the field of medicine, this is useful to support a spiritual approach which is discussed in palliative treatment. The philosophy developed by Jaspers can be considered as indicating a practical form of guidance for people to find self-support from a limit situation where they have lost their own support, and finally, come to a degree of mutual acceptance. Mutual acceptance is made possible at the level of ciphers, in which specific meaning remains undefined, by directing both the self and the other toward a state of "transcendence". Nowadays there is a trend for those chaplains involved in spiritual care from a specialist point of view to be trained to effectively transcend any difference in religious belief. As a basic premise, the author considers there is a need to once again return to a state before the start of individual religions, and stand on a cross-sectional ground level, an area which could be regarded as common to all religions. When conducting such a task, in the author's view, the restrained spirituality that Jaspers expounded is thought-provoking.

Value as the key concept in the health care system: how it has influenced medical practice and clinical decision-making processes.

PubMed

Marzorati, Chiara; Pravettoni, Gabriella

2017-01-01

In the last 10 years, value has played a key role in the health care system. In this concept, innovations in medical practice and the increasing importance of patient centeredness have contributed to draw the attention of the medical community. Nonetheless, a large consensus on the meaning of "value" is still lacking: patients, physicians, policy makers, and other health care professionals have different ideas on which component of value may play a prominent role. Yet, shared clinical decision-making and patient empowerment have been recognized as fundamental features of the concept of value. Different paradigms of health care system embrace different meanings of value, and the absence of common and widely accepted definition does not help to identify a unique model of care in health care system. Our aim is to provide an overview of those paradigms that have considered value as a key theoretical concept and to investigate how the presence of value can influence the medical practice. This article may contribute to draw attention toward patients and propose a possible link between health care system based on "value" and new paradigms such as patient-centered system (PCS), patient empowerment, and P5 medicine, in order to create a predictive, personalized, preventive, participatory, and psycho-cognitive model to treat patients. Indeed, patient empowerment, value-based system, and P5 medicine seem to shed light on different aspects of a PCS, and this allows a better understanding of people under care.

Students' development of models of magnetic materials, patterns of group activity, and social norms in a physics classroom

NASA Astrophysics Data System (ADS)

Johnson, Andrew P.

1999-11-01

This dissertation is a study of students' model development processes in a physical science course for preservice elementary teachers. It details the models of magnetic materials developed and used by students during a unit on static electricity and magnetism. In this inquiry-based course, the class developed and formally accepted a model, in the form of diagrams and descriptions, that is very similar to the accepted magnetic domains model. They did this without textbooks or lectures on magnetism. Before adopting this model, however, most groups in the class temporarily used models involving opposite charges at the two ends of magnetized nails. How did the students do it? The explanation involves detailed study of the groups' interactions and use of structure in the classroom environment. This dissertation uses two theoretical frameworks to analyze interactions. It applies Yackel and Cobb's (1996) concepts of classroom social norms to characterize aspects of the classroom participation structure which affected groups' construction and declaration of models. It also applies distributed cognition ideas to analyze the sense-making conversations that small groups had when constructing group responses. This research found that conversations in one small group could be characterized into sixteen categories. Important categories included "extending ideas" which involved gradual deepening and elaboration of the group's understanding of their model(s), and "joint typing", an interactive process by which group members collaborated on typed statements or group diagrams and simultaneously developed common language for communicating their ideas to each other. Some of these categories of activity were closely connected to computer use. Also, four classroom norms are described. One small group social classroom norm involved group members developing a "common ground" consisting of agreed-upon group statements. Three sociophysics norms which characterize the whole class interactions as well as those of the small group involved a distinction between generalizations of phenomena and theoretical statements, class criteria for accepting evidence, and the obligation for each group to have a model of magnetic materials that they could support with acceptable evidence.

Surrogate outcomes: experiences at the Common Drug Review

PubMed Central

2013-01-01

Background Surrogate outcomes are a significant challenge in drug evaluation for health technology assessment (HTA) agencies. The research objectives were to: identify factors associated with surrogate use and acceptability in Canada’s Common Drug Review (CDR) recommendations, and compare the CDR with other HTA or regulatory agencies regarding surrogate concerns. Methods Final recommendations were identified from CDR inception (September 2003) to December 31, 2010. Recommendations were classified by type of outcome (surrogate, final, other) and acceptability of surrogates (determined by the presence/absence of statements of concern regarding surrogates). Descriptive and statistical analyses examined factors related to surrogate use and acceptability. For thirteen surrogate-based submissions, recommendations from international HTA and regulatory agencies were reviewed for statements about surrogate acceptability. Results Of 156 final recommendations, 68 (44%) involved surrogates. The overall ‘do not list’ (DNL) rate was 48%; the DNL rate for surrogates was 41% (p = 0.175). The DNL rate was 64% for non-accepted surrogates (n = 28) versus 25% for accepted surrogates (odds ratio 5.4, p = 0.002). Clinical uncertainty, use of economic evidence over price alone, and a premium price were significantly associated with non-accepted surrogates. Surrogates were used most commonly for HIV, diabetes, rare diseases, cardiovascular disease and cancer. For the subset of drugs studied, other HTA agencies did not express concerns for most recommendations, while regulatory agencies frequently stated surrogate acceptance. Conclusions The majority of surrogates were accepted at the CDR. Non-accepted surrogates were significantly associated with clinical uncertainty and a DNL recommendation. There was inconsistency of surrogate acceptability across several international agencies. Stakeholders should consider collaboratively establishing guidelines on the use, validation, and acceptability of surrogates. PMID:24341379

Does the acceptance of hybrid learning affect learning approaches in France?

Acceptance of a learning technology affects students' intention to use that technology, but the influence of the acceptance of a learning technology on learning approaches has not been investigated in the literature. A deep learning approach is important in the field of health, where links must be created between skills, knowledge, and habits. Our hypothesis was that acceptance of a hybrid learning model would affect students' way of learning. We analysed these concepts, and their correlations, in the context of a flipped classroom method using a local learning management system. In a sample of all students within a single year of study in the midwifery program (n= 38), we used 3 validated scales to evaluate these concepts (the Study Process Questionnaire, My Intellectual Work Tools, and the Hybrid E-Learning Acceptance Model: Learner Perceptions). Our sample had a positive acceptance of the learning model, but a neutral intention to use it. Students reported that they were distractible during distance learning. They presented a better mean score for the deep approach than for the superficial approach (P< 0.001), which is consistent with their declared learning strategies (personal reorganization of information; search and use of examples). There was no correlation between poor acceptance of the learning model and inadequate learning approaches. The strategy of using deep learning techniques was moderately correlated with acceptance of the learning model (r s = 0.42, P= 0.03). Learning approaches were not affected by acceptance of a hybrid learning model, due to the flexibility of the tool. However, we identified problems in the students' time utilization, which explains their neutral intention to use the system.

Technology acceptance has become a key concept for the successful rollout of technical devices. Though the concept is intensively studied for nearly 20 years now, still, many open questions remain. This especially applies to technology acceptance of older users, which are known to be very sensitive to suboptimal interfaces and show considerable reservations towards the usage of new technology. Mobile small screen technology increasingly penetrates health care and medical applications. This study investigates impacts of aging, technology expertise and domain knowledge on user interaction using the example of diabetes. For this purpose user effectiveness and efficiency have been measured on a simulated small screen device and related to user characteristics, showing that age and technology expertise have a big impact on usability of the device. Furthermore, impacts of user characteristics and success during the trial on acceptance of the device were surveyed and analyzed.

ASME Material Challenges for Advanced Reactor Concepts

This study presents the material Challenges associated with Advanced Reactor Concept (ARC) such as the Advanced High Temperature Reactor (AHTR). ACR are the next generation concepts focusing on power production and providing thermal energy for industrial applications. The efficient transfer of energy for industrial applications depends on the ability to incorporate cost-effective heat exchangers between the nuclear heat transport system and industrial process heat transport system. The heat exchanger required for AHTR is subjected to a unique set of conditions that bring with them several design challenges not encountered in standard heat exchangers. The corrosive molten salts, especially at highermore » temperatures, require materials throughout the system to avoid corrosion, and adverse high-temperature effects such as creep. Given the very high steam generator pressure of the supercritical steam cycle, it is anticipated that water tube and molten salt shell steam generators heat exchanger will be used. In this paper, the ASME Section III and the American Society of Mechanical Engineers (ASME) Section VIII requirements (acceptance criteria) are discussed. Also, the ASME material acceptance criteria (ASME Section II, Part D) for high temperature environment are presented. Finally, lack of ASME acceptance criteria for thermal design and analysis are discussed.« less

Smart spaces foster the development of natural and appropriate forms of human-computer interaction by taking advantage of home customization. The interaction potential of the Smart Home, which is a special type of smart space, is of particular interest in fields in which the acceptance of new technologies is limited and restrictive. The integration of smart home design patterns with sensitive solutions can increase user acceptance. In this paper, we present the main challenges that have been identified in the literature for the successful deployment of sensitive services (e.g., telemedicine and assistive services) in smart spaces and a software architecture that models the functionalities of a Smart Home platform that are required to maintain and support such sensitive services. This architecture emphasizes user interaction as a key concept to facilitate the acceptance of sensitive services by end-users and utilizes activity theory to support its innovative design. The application of activity theory to the architecture eases the handling of novel concepts, such as understanding of the system by patients at home or the affordability of assistive services. Finally, we provide a proof-of-concept implementation of the architecture and compare the results with other architectures from the literature.

2013-04-01

This paper documents current understanding of acceptance as a security management approach and explores issues and challenges non-governmental organisations (NGOs) confront when implementing an acceptance approach to security management. It argues that the failure of organisations to systematise and clearly articulate acceptance as a distinct security management approach and a lack of organisational policies and procedures concerning acceptance hinder its efficacy as a security management approach. The paper identifies key and cross-cutting components of acceptance that are critical to its effective implementation in order to advance a comprehensive and systematic concept of acceptance. The key components of acceptance illustrate how organisational and staff functions affect positively or negatively an organisation's acceptance, and include: an organisation's principles and mission, communications, negotiation, programming, relationships and networks, stakeholder and context analysis, staffing, and image. The paper contends that acceptance is linked not only to good programming, but also to overall organisational management and structures. © 2013 The Author(s).

A Common-Fate Analysis of Pornography Acceptance, Use, and Sexual Satisfaction Among Heterosexual Married Couples.

2017-02-01

Using matched, heterosexual couple data from the Relationship Evaluation Questionnaire (RELATE; n = 326 couples), an adapted common-fate approach was used to examine both common and unique attributes of husbands' and wives' acceptance of pornography and sexual satisfaction as well as husbands' and wives' pornography use. It was expected that spouses' unique as well as shared variance of pornography acceptance would be significantly associated with husbands' and wives' levels of personal pornography use and that these use patterns would be significantly associated with husbands' and wives' unique as well as shared variance of sexual satisfaction. It was also expected that pornography use would significantly mediate the relationship between pornography acceptance and sexual satisfaction. Results indicated that the shared variance of pornography acceptance was positively associated with both spouses' pornography use and that spouses' pornography use was negatively associated with their own sexual satisfaction. Wives' pornography use was found to be positively associated with the couple's shared variance of sexual satisfaction, but pornography use did not significantly mediate the relationship between pornography acceptance and sexual satisfaction. These findings emphasize the complexity of pornography use in couple relationships and the importance of studying pornography acceptance and use as a coupling dynamic within marriages rather than just an individual behavior.

Emotional and rational disease acceptance in patients with depression and alcohol addiction.

2008-01-21

The concept of a rational respectively emotional acceptance of disease is highly valued in the treatment of patients with depression or addiction. Due to the importance of this concept for the long-term course of disease, there is a strong interest to develop a tool to identify the levels and factors of acceptance. We thus intended to test an instrument designed to assess the level of positive psychological wellbeing and coping, particularly emotional disease acceptance and life satisfaction In an anonymous cross-sectional survey enrolling 115 patients (51% female, 49% male; mean age 47.6 +/- 10.0 years) with depression and/or alcohol addiction, the ERDA questionnaire was tested. Factor analysis of the 29-item construct (Cronbach's alpha = 0.933) revealed a 4-factor solution, which explained 59.4% of variance: (1) Positive Life Construction, Contentedness and Well-Being; (2) Conscious Dealing with Illness; (3) Rejection of an Irrational Dealing with Disease; (4) Disease Acceptance. Two factors could be ascribed to a rational, and two to an emotional acceptance. All factors correlated negatively with Depression and Escape, while several aspects of Life Satisfaction" (i.e. myself, overall life, where I live, and future prospects) correlated positively. The highest factor scores were found for the rational acceptance styles (i.e. Conscious Dealing with Illness; Disease Acceptance). Emotional acceptance styles were not valued in a state of depression. Escape from illness was the strongest predictor for several acceptance aspects, while life satisfaction was the most relevant predictor for "Positive Life Construction, Contentedness and Well-Being". The ERDA questionnaire was found to be a reliable and valid assessment of disease acceptance strategies in patients with depressive disorders and drug abuses. The results indicate the preferential use of rational acceptance styles even in depression. Disease acceptance should not be regarded as a coping style with an attitude of fatalistic resignation, but as a complex and active process of dealing with a chronic disease. One may assume that an emotional acceptance of disease will result in a therapeutic coping process associated with higher level of life satisfaction and overall quality of life.

An examination of conceptual change in undergraduate biology majors while learning science concepts including biological evolution

NASA Astrophysics Data System (ADS)

McQuaide, Glenn G.

2006-12-01

Without adequate understanding of science, we cannot make responsible personal, regional, national, or global decisions about any aspect of life dealing with science. Better understanding how we learn about science can contribute to improving the quality of our educational experiences. Promoting pathways leading to life-long learning and deep understanding in our world should be a goal for all educators. This dissertation project was a phenomenological investigation into undergraduate understanding and acceptance of scientific theories, including biological evolution. Specifically, student descriptions of conceptual change while learning science theory were recorded and analyzed. These qualitative investigations were preceded by a survey that provided a means of selecting students who had a firmer understanding of science theory. Background information and survey data were collected in an undergraduate biology class at a small, Southern Baptist-affiliated liberal arts school located in south central Kentucky. Responses to questions on the MATE (Rutledge and Warden, 1999) instrument were used to screen students for interviews, which investigated the way by which students came to understand and accept scientific theories. This study identifies some ways by which individuals learn complex science theories, including biological evolution. Initial understanding and acceptance often occurs by the conceptual change method described by Posner et al. (1982). Three principle ways by which an individual may reach a level of understanding and acceptance of science theory were documented in this study. They were conceptual change through application of logic and reasoning; conceptual change through modification of religious views; and conceptual change through acceptance of authoritative knowledge. Development of a deeper, richer understanding and acceptance of complex, multi-faceted concepts such as biological evolution occurs in some individuals by means of conceptual enrichment. Conceptual enrichment occurs through addition of new knowledge, and then examining prior knowledge through the perspective of this new knowledge. In the field of science, enrichment reinforces complex concepts when multiple, convergent lines of supporting evidences point to the same rational scientific conclusion.

In this qualitative study of 10 lesbian couples who built their families through anonymous donor conception, we explore how lesbian parents experience communication about the donor conception within the family. While for these families "disclosure" of donor conception is often seen as evident, the way parents and children discuss this subject and how this is experienced by the parents themselves has not received much research attention. To meet this gap in the literature, in-depth interviews with lesbian couples were conducted. An Interpretative Phenomenological Analysis showed that this family communication process can be understood within the broader relational context of parent-child relationships. Even though parents handled this family communication in many different ways, these were all inspired by the same motives: acting in the child's best interest and-on a more implicit level-maintaining good relations within the family. Furthermore, parents left the initiative for talking about the DC mostly to the child. Overall, parents aimed at constructing a donor conception narrative that they considered acceptable for both the children and themselves. They used different strategies, such as gradual disclosure, limiting the meaning of the donor, and justifying the donor conception. Building an acceptable donor conception narrative was sometimes challenged by influences from the social environment. In the discussion, we relate this qualitative systemic study to the broader issues of selective disclosure and bidirectionality within families. © 2014 Family Process Institute.

China has undergone massive socio-economic change over the past 30 years. In parallel, there have been huge changes in social and sexual mores. Until the end of the Mao era strict norms prevailed, with sex outside marriage widely regarded as immoral and unacceptable. Detraditionalisation theory describes the abandonment or reconfiguration of the socio-cultural traditions and has been explored widely in Western settings. This study aimed to explore its relevance for China through exploring attitudes towards premarital sex, extramarital sex, same-sex relations and sex work. We conducted semi-structured interviews with 212 men and women aged 18 to 39 in urban and rural areas of three provinces: Zhejiang, Guizhou and Yunnan. Analysis identified emerging themes. Results show varying degrees of acceptance of the four sexual behaviours, with premarital sex seen as common, homosexuality still regarded as unacceptable by the majority but considerable acceptance of commercial sex work as part of male business transactions and social life. China appears to be on a pathway of detraditionalisation with specific Chinese features. This study suggests that the concept of detraditionalisation applies well to non-Western contexts, but the path it takes is culture-specific and relatively unpredictable. © 2011 Taylor & Francis

Trade in human tissue products.

Trade in human tissue in Australia is prohibited by state law, and in ethical guidelines by the National Health and Medical Research Council: National statement on ethical conduct in human research; Organ and tissue donation by living donors: guidelines for ethical practice for health professionals. However, trade in human tissue products is a common practice especially for: reconstructive orthopaedic or plastic surgery; novel human tissue products such as a replacement trachea created by using human mesenchymal stem cells; biomedical research using cell lines, DNA and protein provided through biobanks. Cost pressures on these have forced consideration of commercial models to sustain their operations. Both the existing and novel activities require a robust framework to enable commercial uses of human tissue products while maintaining community acceptability of such practices, but to date no such framework exists. In this article, we propose a model ethical framework for ethical governance which identifies specific ethical issues such as: privacy; unique value of a person's tissue; commodification of the body; equity and benefit to the community; perverse incentives; and "attenuation" as a potentially useful concept to help deal with the broad range of subjective views relevant to whether it is acceptable to commercialise certain human tissue products.

Changing concepts of geologic structure and the problem of siting nuclear reactors: Examples from Washington State

NASA Astrophysics Data System (ADS)

Tabor, R. W.

1986-09-01

The conflict between regulation and healthy evolution of geological science has contributed to the difficulties of siting nuclear reactors. On the Columbia Plateau in Washington, but for conservative design of the Hanford reactor facility, the recognition of the little-understood Olympic-Wallowa lineament as a major, possibly still active structural alinement might have jeopardized the acceptability of the site for nuclear reactors. On the Olympic Peninsula, evolving concepts of compressive structures and their possible recent activity and the current recognition of a subducting Juan de Fuca plate and its potential for generating great earthquakes—both concepts little-considered during initial site selection—may delay final acceptance of the Satsop site. Conflicts of this sort are inevitable but can be accommodated if they are anticipated in the reactor-licensing process. More important, society should be increasing its store of geologic knowledge now, during the current recess in nuclear reactor siting.

Promotion of Nursing Student Civility in Nursing Education: A Concept Analysis.

PubMed

Woodworth, Julie A

2016-07-01

Substantive research into the development of civility within nursing education is long overdue. Behaviors learned by nursing students while in the school of nursing transfer to the work environment and culture of nursing. This paper reveals a concept analysis of civility within nursing education using Rodgers' evolutionary concept analysis method. Civility is defined to provide clarity for the current terminology of civility within nursing education. Nurse educators must set socially acceptable behavioral expectations in the learning environment, establishing positive interpersonal relationships with students, maintaining moral and academic integrity, and role model civil behaviors. Suggestions are included to help nurse educators outline acceptable behaviors in the learning environment and promote the development of civility. The development of civil behaviors in nursing students will carry into professional practice after graduation. Civility is necessary to establish meaningful interpersonal relationships, supportive communication, and optimum learning environments to ensure quality patient care with optimum outcomes.

Advanced Propulsion System Studies in High Speed Research

Zola, Charles L.

2000-01-01

Propulsion for acceptable supersonic passenger transport aircraft is primarily impacted by the very high jet noise characteristics of otherwise attractive engines. The mixed flow turbofan, when equipped with a special ejector nozzle seems to be the best candidate engine for this task of combining low jet noise with acceptable flight performance. Design, performance, and operation aspects of mixed flow turbofans are discussed. If the special silencing nozzle is too large, too heavy, or not as effective as expected, alternative concepts in mixed flow engines should be examined. Presented herein is a brief summary of efforts performed under cooperative agreement NCC3-193. Three alternative engine concepts, conceived during this study effort, are herein presented and their limitations and potentials are described. These three concepts intentionally avoid the use of special silencing nozzles and achieve low jet noise by airflow augmentation of the engine cycle.

[Kaiseijutsu and obstetrics in Osaka during the Yedo era: focusing mainly on the development of surgical operations in obstetrics].

PubMed

Uchino, Hanna

2009-03-01

In the Yedo era, the Kamigata area was the place of dispatch of new cultures and was the seat of the economy. However, because natural disasters happened frequently, the economic differential between the central area and the provinces grew wider. The families who suffered poverty sold their daughters to the licensed quarters. Moreover, among the general public, there were a lot of foundlings and women who had abortions. Indeed, we can find these phenomena throughout the Yedo era. Early in the era, such cases were regarded as very common; for example, in IHARA Saikaku works, which describes scenes in Osaka early in the Yedo era, there are a lot of descriptions of foundlings and women who had abortions as common social phenomena. However, in the middle of the era, these phenomena came to be considered sins, as they were in Saikaku's works. This transition period of conceptions about foundlings or abortions coincided with changes in technology in obstetrics. Early in the era when dystocia occurred, both mothers and babies could only be expected to die, and in the middle, after the invention of Kaiseijutsu, which was designed by KAGAWA Gen'etsu, obstetricians could help a lot of women in childbirth. However, when abortions came to be regarded as a sin, people accepted Kaiseijutsu because of the concept of life and because it could help women in childbed and babies as medicine, before everything else.

[Could infant euthanasia be ever acceptable?].

2014-10-01

The recent enactment of a law that allows infant euthanasia in Belgium raises questions with varied answers. To contribute to a better understanding of the topic, euthanasia and legislation concepts are described. After a bioethical analysis, we propose as conclusion that children euthanasia could only be acceptable in very exceptional situations in which palliative measures have failed. The answer should be that it is not acceptable in our setting, not until we have public policies, protocols and palliative care services for terminally ill children.

The molecular biology capstone assessment: a concept assessment for upper-division molecular biology students.

2015-03-02

Measuring students' conceptual understandings has become increasingly important to biology faculty members involved in evaluating and improving departmental programs. We developed the Molecular Biology Capstone Assessment (MBCA) to gauge comprehension of fundamental concepts in molecular and cell biology and the ability to apply these concepts in novel scenarios. Targeted at graduating students, the MBCA consists of 18 multiple-true/false (T/F) questions. Each question consists of a narrative stem followed by four T/F statements, which allows a more detailed assessment of student understanding than the traditional multiple-choice format. Questions were iteratively developed with extensive faculty and student feedback, including validation through faculty reviews and response validation through student interviews. The final assessment was taken online by 504 students in upper-division courses at seven institutions. Data from this administration indicate that the MBCA has acceptable levels of internal reliability (α=0.80) and test-retest stability (r=0.93). Students achieved a wide range of scores with a 67% overall average. Performance results suggest that students have an incomplete understanding of many molecular biology concepts and continue to hold incorrect conceptions previously documented among introductory-level students. By pinpointing areas of conceptual difficulty, the MBCA can provide faculty members with guidance for improving undergraduate biology programs. © 2015 B. A. Couch et al.

Privacy is a complicated and obscure concept, which has special meanings in the healthcare environment; therefore, it is essential for healthcare providers to fully understand this concept. However, there is no universally accepted definition for this concept in the texts, and it has been interpreted differently, based on its application. To analyze and provide a clear and scientific definition for respect of privacy of hospitalized patients and identify the common aspects of this concept. This study was conducted using the Whittemore and Knafl's modified framework as a conceptual analysis method. Ethical consideration: This study was approved by the Research Council of the University of Social Welfare and Rehabilitation Sciences. We have respected the ethical requirements required regarding the sources and authorship. Research context and data sources: Using integrative review, a search was performed using national and international databases, including CINAHL, Scopus, Medline, Web of Science, and ISI (with no date restriction). The keywords employed during the search process were "privacy of patients," "confidentiality," "and patients' rights." In total, 1345 articles were retrieved from the databases. After the elimination of repetitive studies and with regard to the study objectives, 124 articles, 3 books, and 4 theses were entered into the study. The data were analyzed using the conventional content analysis approach. The results were extracted in the form of four, seven, and two themes related to attributes such as physical, informational, social, and psychological and the antecedents and consequences of respecting patient privacy, respectively. Respect for hospitalized patient privacy contains multiple dimensions. Factors affecting the achievement of this concept include individual backgrounds, nature of the disease, and rule of paternalism. The fulfillment of patient privacy leads to such consequences as protection and improvement of human dignity as well as improved communication between the patient and the health team.

Advancing the argument for validity of the Alberta Context Tool with healthcare aides in residential long-term care

PubMed Central

2011-01-01

Background Organizational context has the potential to influence the use of new knowledge. However, despite advances in understanding the theoretical base of organizational context, its measurement has not been adequately addressed, limiting our ability to quantify and assess context in healthcare settings and thus, advance development of contextual interventions to improve patient care. We developed the Alberta Context Tool (the ACT) to address this concern. It consists of 58 items representing 10 modifiable contextual concepts. We reported the initial validation of the ACT in 2009. This paper presents the second stage of the psychometric validation of the ACT. Methods We used the Standards for Educational and Psychological Testing to frame our validity assessment. Data from 645 English speaking healthcare aides from 25 urban residential long-term care facilities (nursing homes) in the three Canadian Prairie Provinces were used for this stage of validation. In this stage we focused on: (1) advanced aspects of internal structure (e.g., confirmatory factor analysis) and (2) relations with other variables validity evidence. To assess reliability and validity of scores obtained using the ACT we conducted: Cronbach's alpha, confirmatory factor analysis, analysis of variance, and tests of association. We also assessed the performance of the ACT when individual responses were aggregated to the care unit level, because the instrument was developed to obtain unit-level scores of context. Results Item-total correlations exceeded acceptable standards (> 0.3) for the majority of items (51 of 58). We ran three confirmatory factor models. Model 1 (all ACT items) displayed unacceptable fit overall and for five specific items (1 item on adequate space for resident care in the Organizational Slack-Space ACT concept and 4 items on use of electronic resources in the Structural and Electronic Resources ACT concept). This prompted specification of two additional models. Model 2 used the 7 scaled ACT concepts while Model 3 used the 3 count-based ACT concepts. Both models displayed substantially improved fit in comparison to Model 1. Cronbach's alpha for the 10 ACT concepts ranged from 0.37 to 0.92 with 2 concepts performing below the commonly accepted standard of 0.70. Bivariate associations between the ACT concepts and instrumental research utilization levels (which the ACT should predict) were statistically significant at the 5% level for 8 of the 10 ACT concepts. The majority (8/10) of the ACT concepts also showed a statistically significant trend of increasing mean scores when arrayed across the lowest to the highest levels of instrumental research use. Conclusions The validation process in this study demonstrated additional empirical support for construct validity of the ACT, when completed by healthcare aides in nursing homes. The overall pattern of the data was consistent with the structure hypothesized in the development of the ACT and supports the ACT as an appropriate measure for assessing organizational context in nursing homes. Caution should be applied in using the one space and four electronic resource items that displayed misfit in this study with healthcare aides until further assessments are made. PMID:21767378

Voluntary Consent: Why a Value-Neutral Concept Won’t Work

Wertheimer, Alan

2012-01-01

Some maintain that voluntariness is a value-neutral concept. On that view, someone acts involuntarily if subject to a controlling influence or has no acceptable alternatives. I argue that a value-neutral conception of voluntariness cannot explain when and why consent is invalid and that we need a moralized account of voluntariness. On that view, most concerns about the voluntariness of consent to participate in research are not well founded. PMID:22551878

To evaluate the concepts and attitudes of patients and their immediate family members towards diabetes, its complications, and treatment. A total of 654 patients with poorly controlled diabetes and 216 of their immediate family members were interviewed regarding their concept about diabetes, its complications, diet, exercise, drug therapy, and understanding about insulin. There was lack of awareness about diabetes and its complications among the patients of diabetes. Majority of obese patients and their close family members failed to accept that they were obese. Child birth, menopause, and tubal ligation in female patients were wrongly attributed as a cause of obesity. There were major misconceptions about diet, exercise, and insulin therapy. More than 90% of study subjects had a misconception that all sweet fruits are prohibited and all bitter vegetables are beneficial. Temporary discontinuation of drug therapy was found in 189 cases. The lack of awareness and various misconceptions had no statistical relationship with the educational background of the patients. Among patients of poorly controlled diabetes and their close family members, there was a gross lack of knowledge of complications of diabetes, causes of obesity, treatment of diabetes, and use of insulin. Denial of obesity was commonly observed. Linking obesity with tubal ligation in female patients not only is appalling but may possibly be a hindrance to family planning program. Level of education had no bearing on these misconceptions. Copyright © 2010 Elsevier Inc. All rights reserved.

To investigate the concept of hope for families and pediatric health care professionals during a child's serious illness. Eight focus groups. Academic pediatric medical center. Bereaved parents, pediatricians, pediatric residents, and nurses (N = 39). Intervention Participants were asked standardized questions related to their definition of hope, its role in medical decisions, and the benefits and detriments of hope in focus group sessions. We identified attributes of participants' concepts of hope using qualitative analysis of audio-taped sessions. While all participants identified common elements in their definition of hope, parents identified their role as bearers of hope; it was a cornerstone of decision making. Health care professionals tended to view hope as related to a positive outcome. Some physicians reported difficulty in maintaining hope in the face of prognostic data; others acknowledged the importance of the family's hope. Nurses identified particular challenges around parents' decisions to continue treatment when it prolonged the child's suffering. All participants noted the changing nature of hope and its implications for care. The tension between maintaining hope and accepting the reality of the prognosis may lessen when acknowledging that parents see their role as bearers of hope. Supporting families around the changing nature of hope may allow health care professionals to partner with parents while maintaining honest communication.

This paper explores notions of fatherhood and their linkages to fertility desires and intentions among a treatment-naïve cohort of Xhosa-speaking male key informants living with HIV aged 20-53 in Cape Town, South Africa. Analysis is based on an initial 27 and 20 follow up interviews with men who were part of a study that assessed the acceptability of safer conception and alternative parenting strategies among men and women newly diagnosed with HIV to inform an intervention. Grounded theory analysis revealed themes related to the cultural imperative of biologically-connected fatherhood. Certain safer conception strategies aimed at minimising the risk of HIV transmission were perceived as threats to paternity. These findings suggest that understanding of social and cultural beliefs related to notions of paternity and fatherhood may inform the implementation of acceptable safer conception options for HIV-positive men and their infected and uninfected female partners in a high HIV prevalence, low-resource setting.

Penicillium is a diverse genus occurring worldwide and its species play important roles as decomposers of organic materials and cause destructive rots in the food industry where they produce a wide range of mycotoxins. Other species are considered enzyme factories or are common indoor air allergens. Although DNA sequences are essential for robust identification of Penicillium species, there is currently no comprehensive, verified reference database for the genus. To coincide with the move to one fungus one name in the International Code of Nomenclature for algae, fungi and plants, the generic concept of Penicillium was re-defined to accommodate species from other genera, such as Chromocleista, Eladia, Eupenicillium, Torulomyces and Thysanophora, which together comprise a large monophyletic clade. As a result of this, and the many new species described in recent years, it was necessary to update the list of accepted species in Penicillium. The genus currently contains 354 accepted species, including new combinations for Aspergillus crystallinus, A. malodoratus and A. paradoxus, which belong to Penicillium section Paradoxa. To add to the taxonomic value of the list, we also provide information on each accepted species MycoBank number, living ex-type strains and provide GenBank accession numbers to ITS, β-tubulin, calmodulin and RPB2 sequences, thereby supplying a verified set of sequences for each species of the genus. In addition to the nomenclatural list, we recommend a standard working method for species descriptions and identifications to be adopted by laboratories working on this genus.

To describe tobacco industry consumer research to inform the development of more "socially acceptable" cigarette products since the 1970s. Analysis of previously secret tobacco industry documents. 28 projects to develop more socially acceptable cigarettes were identified from Philip Morris, RJ Reynolds, British American Tobacco, and Lorillard tobacco companies. Consumer research and concept testing consistently demonstrated that many smokers feel strong social pressure not to smoke, and this pressure increased with exposure to smoking restrictions. Tobacco companies attempted to develop more socially acceptable cigarettes with less visible sidestream smoke or less odour. When presented in theory, these product concepts were very attractive to important segments of the smoking population. However, almost every product developed was unacceptable in actual product tests or test markets. Smokers reported the complete elimination of secondhand smoke was necessary to satisfy non-smokers. Smokers have also been generally unwilling to sacrifice their own smoking satisfaction for the benefit of others. Many smokers prefer smoke-free environments to cigarettes that produce less secondhand smoke. Concerns about secondhand smoke and clean indoor air policies have a powerful effect on the social acceptability of smoking. Historically, the tobacco industry has been unable to counter these effects by developing more socially acceptable cigarettes. These data suggest that educating smokers about the health dangers of secondhand smoke and promoting clean indoor air policies has been difficult for the tobacco industry to counter with new products, and that every effort should be made to pursue these strategies.

Wendelberger, Karen J.; Burke, Rebecca; Haas, Arthur L.; Harenwattananon, Marisa; Simpson, Deborah

1998-01-01

Objectives: Retention of basic science knowledge, as judged by National Board of Medical Examiners' (NBME) data, suffers due to lack of apparent relevance and isolation of instruction from clinical application, especially in biochemistry. However, the literature reveals no systematic process for identifying key biochemical concepts and associated clinical conditions. This study systematically identified difficult biochemical concepts and their common clinical conditions as a critical step towards enhancing relevance and retention of biochemistry.Methods: A multi-step/ multiple stakeholder process was used to: (1) identify important biochemistry concepts; (2) determine students' perceptions of concept difficulty; (3) assess biochemistry faculty, student, and clinical teaching scholars' perceived relevance of identified concepts; and (4) identify associated common clinical conditions for relevant and difficult concepts. Surveys and a modified Delphi process were used to gather data, subsequently analyzed using SPSS for Windows.Results: Sixteen key biochemical concepts were identified. Second year medical students rated 14/16 concepts as extremely difficult while fourth year students rated nine concepts as moderately to extremely difficult. On average, each teaching scholar generated common clinical conditions for 6.2 of the 16 concepts, yielding a set of seven critical concepts and associated clinical conditions.Conclusions: Key stakeholders in the instructional process struggle to identify biochemistry concepts that are critical, difficult to learn and associated with common clinical conditions.

NASA Technical Reports Server (NTRS)

Mimbs, Scott M.

2008-01-01

One of the more misunderstood areas of metrology is the Test Uncertainty Ratio (TUR) and the Test Accuracy Ratio (TAR). There have been many definitions over the years, but why are these definitions important to a discussion on measurement decision risk? The importance lies in the clarity of communication. Problems can immediately arise in the application (or misapplication) of the definition of these terms. In other words, while it is important to understand the definitions, it is more important to understand concepts behind the definitions and to be precise in how they are applied. The objective of any measurement is a decision. Measurement Decision Risk is a way to look at the quality of a measurement, and although it is not a new concept, it has generated a lot of attention since its addition as a requirement in the new U.S. National Standard, ANSIINCSL Z540.3-2006. In addition to Measurement Decision Risk as the prime method of managing measurement risk, Z540.3 has added, as a fall-back, an explicit definition for TUR. The impact these new requirements may have on calibration service providers has become the topic of much discussion and in some cases concern. This paper will look at the concepts behind the definitions and how they relate to Measurement Decision Risk. Using common examples, this paper will also provide a comparison of various elements of risk related to measurement science using the concepts of TAR, TUR, accuracy ratios, and Consumer Risk (False Accept Risk). The goal of this paper is to provide a better understanding of their relevance to the measurement decision process.

Value as the key concept in the health care system: how it has influenced medical practice and clinical decision-making processes

Marzorati, Chiara; Pravettoni, Gabriella

2017-01-01

In the last 10 years, value has played a key role in the health care system. In this concept, innovations in medical practice and the increasing importance of patient centeredness have contributed to draw the attention of the medical community. Nonetheless, a large consensus on the meaning of “value” is still lacking: patients, physicians, policy makers, and other health care professionals have different ideas on which component of value may play a prominent role. Yet, shared clinical decision-making and patient empowerment have been recognized as fundamental features of the concept of value. Different paradigms of health care system embrace different meanings of value, and the absence of common and widely accepted definition does not help to identify a unique model of care in health care system. Our aim is to provide an overview of those paradigms that have considered value as a key theoretical concept and to investigate how the presence of value can influence the medical practice. This article may contribute to draw attention toward patients and propose a possible link between health care system based on “value” and new paradigms such as patient-centered system (PCS), patient empowerment, and P5 medicine, in order to create a predictive, personalized, preventive, participatory, and psycho-cognitive model to treat patients. Indeed, patient empowerment, value-based system, and P5 medicine seem to shed light on different aspects of a PCS, and this allows a better understanding of people under care. PMID:28356752

Lack of access to health care for African indigents: a social exclusion perspective

PubMed Central

2013-01-01

Background Lack of access to health care is a persistent condition for most African indigents, to which the common technical approach of targeting initiatives is an insufficient antidote. To overcome the standstill, an integrated technical and political approach is needed. Such policy shift is dependent on political support, and on alignment of international and national actors. We explore if the analytical framework of social exclusion can contribute to the latter. Methods We produce a critical and evaluative account of the literature on three themes: social exclusion, development policy, and indigence in Africa–and their interface. First, we trace the concept of social exclusion as it evolved over time and space in policy circles. We then discuss the relevance of a social exclusion perspective in developing countries. Finally, we apply this perspective to Africa, its indigents, and their lack of access to health care. Results The concept of social exclusion as an underlying process of structural inequalities has needed two decades to find acceptance in international policy circles. Initial scepticism about the relevance of the concept in developing countries is now giving way to recognition of its universality. For a variety of reasons however, the uptake of a social exclusion perspective in Africa has been limited. Nevertheless, social exclusion as a driver of poverty and inequity in Africa is evident, and manifestly so in the case of the African indigents. Conclusion The concept of social exclusion provides a useful framework for improved understanding of origins and persistence of the access problem that African indigents face, and for generating political space for an integrated approach.

Rogo, C.; Hajek, T.; Chen, A. G.

1984-01-01

A radial turbine stage with a variable area nozzle was investigated. A high work capacity turbine design with a known high performance base was modified to accept a fixed vane stagger angle moveable sidewall nozzle. The nozzle area was varied by moving the forward and rearward sidewalls. Diffusing and accelerating rotor inlet ramps were evaluated in combinations with hub and shroud rotor exit rings. Performance of contoured sidewalls and the location of the sidewall split line with respect to the rotor inlet was compared to the baseline. Performance and rotor exit survey data are presented for 31 different geometries. Detail survey data at the nozzle exit are given in contour plot format for five configurations. A data base is provided for a variable geometry concept that is a viable alternative to the more common pivoted vane variable geometry radial turbine.

[How to manage with rigour but flexibility an orthodontic practice].

PubMed

Binhas, Edmond; Binhas, Corinne

2017-03-01

An orthodontic office owner must understand the context and then combine logic, emotion, intuition and common sense. The productivity approach is no longer acceptable. It is necessary to combine rigour, flexibility and pragmatism. The obsessive perfectionism is ineffective. In fact, there are four ways to demonstrate a flexible determination: persevere when appropriate, win the support of your entourage, back on some decisions, appeal to the collective will. Another needed feature is to have the flexibility to change its own habits and change the ones of others. Some practical examples based on the five available resources (time, money, people, training and equipment) illustrate the concepts discussed. Both qualities are necessary for the orthodontic business manager today: strong leadership and flexibility. The best attitude lies in the combination of these two seemingly contradictory requirements. © EDP Sciences, SFODF, 2017.

A generic, web-based clinical information system architecture using HL7 CDA: successful implementation in dermatological routine care.

Schuler, Thilo; Boeker, Martin; Klar, Rüdiger; Müller, Marcel

2007-01-01

The requirements of highly specialized clinical domains are often underrepresented in hospital information systems (HIS). Common consequences are that documentation remains to be paper-based or external systems with insufficient HIS integration are used. This paper presents a solution to overcome this deficiency in the form of a generic framework based on the HL7 Clinical Document Architecture. The central architectural idea is the definition of customized forms using a schema-controlled XML language. These flexible form definitions drive the user interface, the data storage, and standardized data exchange. A successful proof-of-concept application in a dermatologic outpatient wound care department has been implemented, and is well accepted by the clinicians. Our work with HL7 CDA revealed the need for further practical research in the health information standards realm.

2004-01-01

The importance of cultural competency in all areas of American society is well accepted. Indeed, the evolving demographics of the country make it imperative. A wide range of educational and work settings has addressed the concept, from business and government to education and health. Cultural competency is particularly critical in the realm of healthcare, as the potential impact on quality of health and life is at stake. Nursing is a leader in this field, with a long theoretical and practice history of attention to, and respect for, individual differences. This article reviews cultural competency education in nursing and its respective educational settings. Common threads and different models are discussed. The program components of cultural competency education in one School of Nursing are highlighted. Future directions towards refining cultural competency education are presented.

To review different types of economic analyses commonly found in healthcare literature, discuss methodologic considerations in framing economic analyses, identify useful resources for economic evaluations, and describe the current and potential roles of standardized nursing terminologies in providing cost and outcome data for economic analysis. The Advanced Billing Concepts Code Resource-based Relative Value Scale and Nursing Outcomes Classification. Using case studies, the applicability of standardized nursing terminologies in cost-effectiveness analysis is demonstrated. While there is potential to inform specific questions, comparisons across analyses are limited because of the many outcome measures. Including a standardized quality-of-life measure in nursing terminologies would allow for the calculation of accepted outcome measures and dollars per quality adjusted life years gained. The nurse's ability to assess and contribute to all aspects of rigorous economic evidence is an essential competency for responsible practice.

Inflation of the type I error: investigations on regulatory recommendations for bioequivalence of highly variable drugs.

PubMed

Wonnemann, Meinolf; Frömke, Cornelia; Koch, Armin

2015-01-01

We investigated different evaluation strategies for bioequivalence trials with highly variable drugs on their resulting empirical type I error and empirical power. The classical 'unscaled' crossover design with average bioequivalence evaluation, the Add-on concept of the Japanese guideline, and the current 'scaling' approach of EMA were compared. Simulation studies were performed based on the assumption of a single dose drug administration while changing the underlying intra-individual variability. Inclusion of Add-on subjects following the Japanese concept led to slight increases of the empirical α-error (≈7.5%). For the approach of EMA we noted an unexpected tremendous increase of the rejection rate at a geometric mean ratio of 1.25. Moreover, we detected error rates slightly above the pre-set limit of 5% even at the proposed 'scaled' bioequivalence limits. With the classical 'unscaled' approach and the Japanese guideline concept the goal of reduced subject numbers in bioequivalence trials of HVDs cannot be achieved. On the other hand, widening the acceptance range comes at the price that quite a number of products will be accepted bioequivalent that had not been accepted in the past. A two-stage design with control of the global α therefore seems the better alternative.

Adaptive Software Architecture Based on Confident HCI for the Deployment of Sensitive Services in Smart Homes

2015-01-01

Smart spaces foster the development of natural and appropriate forms of human-computer interaction by taking advantage of home customization. The interaction potential of the Smart Home, which is a special type of smart space, is of particular interest in fields in which the acceptance of new technologies is limited and restrictive. The integration of smart home design patterns with sensitive solutions can increase user acceptance. In this paper, we present the main challenges that have been identified in the literature for the successful deployment of sensitive services (e.g., telemedicine and assistive services) in smart spaces and a software architecture that models the functionalities of a Smart Home platform that are required to maintain and support such sensitive services. This architecture emphasizes user interaction as a key concept to facilitate the acceptance of sensitive services by end-users and utilizes activity theory to support its innovative design. The application of activity theory to the architecture eases the handling of novel concepts, such as understanding of the system by patients at home or the affordability of assistive services. Finally, we provide a proof-of-concept implementation of the architecture and compare the results with other architectures from the literature. PMID:25815449

As part of a larger research program evaluating chemical threshold levels for a Push-Pull intervention to reduce man-vector (Aedes aegypti) contact, this qualitative study explored local perceptions and strategies associated with mosquito control within dengue-endemic communities in Peru and Thailand. Focus groups were used to provide preliminary information that would identify possible public acceptance issues to the Push-Pull strategy in each site. Nine focus group discussions (total of 102 individuals) conducted between September 2008 and March 2009 examined several themes: 1) current mosquito control practices; 2) perceptions of spatial repellency and contact irritancy versus killing mosquitoes; and 3) initial perceptions toward mosquito host-seeking traps. Results indicate participants use household-level strategies for insect control that reveal familiarity with the concept of spatial repellent and contact irritant actions of chemicals and that placing traps in the peridomestic environment to remove repelled mosquitoes was acceptable. Preliminary evidence suggests a Push-Pull strategy should be well accepted in these locations. These results will be beneficial for developing future large scale push-pull interventions and are currently being used to guide insecticide application strategies in (entomological) proof-of-concept studies using experimental huts.

The distinction between reality and models or methodological assumptions is necessary for an understanding of the use of data--economic, technical or biological--in decision-making. The traditional modes of analysis used in decisions are discussed historically and analytically. Utilitarian-based concepts such as cost-benefit analysis and cannibalistic concepts such as "acceptable risk" are rejected on logical and moral grounds. Historical reality suggests the concept of socially necessary risk determined through the dialectic process in democracy. PMID:120251

This paper assesses historical reasons that may account for the marginalization of hormesis as a dose-response model in the biomedical sciences in general and toxicology in particular. The most significant and enduring explanatory factors are the early and close association of the concept of hormesis with the highly controversial medical practice of homeopathy and the difficulty in assessing hormesis with high-dose testing protocols which have dominated the discipline of toxicology, especially regulatory toxicology. The long-standing and intensely acrimonious conflict between homeopathy and 'traditional' medicine (allopathy) lead to the exclusion of the hormesis concept from a vast array of medical- andmore » public health-related activities including research, teaching, grant funding, publishing, professional societal meetings, and regulatory initiatives of governmental agencies and their advisory bodies. Recent publications indicate that the hormetic dose-response is far more common and fundamental than the dose-response models [threshold/linear no threshold (LNT)] used in toxicology and risk assessment, and by governmental regulatory agencies in the establishment of exposure standards for workers and the general public. Acceptance of the possibility of hormesis has the potential to profoundly affect the practice of toxicology and risk assessment, especially with respect to carcinogen assessment.« less

Mobile radio alternative systems study satellite/terrestrial (hybrid) systems concepts

Kiesling, J. D.; Anderson, R. E.

1983-01-01

The use of satellites for mobile radio service in non-urban areas of the United States in the years from 1985 to 2000 was investigated. Several satellite concepts are considered: a system with single-beam coverage of the fifty United States and Puerto Rico, and multi-beam satellites with greater capacity. All of the needed functions and services identified in the market study are provided by the satellite systems, including nationwide radio access to vehicles without knowledge of vehicle location wideband data transmission from remote sites, two way exchange of short data and control messages between vehicles and dispatch or control centers, and automatic vehicle location (surveillance). The costs of providing the services are within acceptable limits, and the desired returns to the system investors are attractive. The criteria by which the Federal Communication judges the competing demands for public radio spectrum are reviewed with comments on how the criteria might apply to the consideration of land mobile satellites. Institutional arrangements for operating a mobile satellite system are based on the present institutional arrangements in which the services are offered to the end users through wireline and radio common carriers, with direct access by large private and government users.

The article explores marketing ethics considerations in the application of marketing to healthcare. While we realize that acceptance of healthcare marketing by all stakeholders is important for successful marketing, we emphasize its level of acceptance by healthcare professionals. The high levels of resistance to advertising and other forms of healthcare marketing by healthcare professionals has been largely based on the grounds that the practices are unethical. The nature of the resistance thus invites this exploration of healthcare marketing (and the marketing concept), marketing ethics, and the acceptance (rejection) by healthcare professionals of healthcare marketing.

Can Fire and Rescue Services and the National Health Service work together to improve the safety and wellbeing of vulnerable older people? Design of a proof of concept study.

PubMed

Lowton, Karen; Laybourne, Anne H; Whiting, David G; Martin, Finbarr C

2010-12-03

Older adults are at increased risk both of falling and of experiencing accidental domestic fire. In addition to advanced age, these adverse events share the risk factors of balance or mobility problems, cognitive impairment and socioeconomic deprivation. For both events, the consequences include significant injury and death, and considerable socioeconomic costs for the individual and informal carers, as well as for emergency services, health and social care agencies.Secondary prevention services for older people who have fallen or who are identifiable as being at high risk of falling include NHS Falls clinics, where a multidisciplinary team offers an individualised multifactorial targeted intervention including strength and balance exercise programmes, medication changes and home hazard modification. A similar preventative approach is employed by most Fire and Rescue Services who conduct Home Fire Safety Visits to assess and, if necessary, remedy domestic fire risk, fit free smoke alarms with instruction for use and maintenance, and plan an escape route. We propose that the similarity of population at risk, location, specific risk factors and the commonality of preventative approaches employed could offer net gains in terms of feasibility, effectiveness and acceptability if activities within these two preventative approaches were to be combined. This prospective proof of concept study, currently being conducted in two London boroughs, (Southwark and Lambeth) aims to reduce the incidence of both fires and falls in community-dwelling older adults. It comprises two concurrent 12-month interventions: the integration of 1) fall risk assessments into the Brigade's Home Fire Safety Visit and 2) fire risk assessments into Falls services by inviting older clinic attendees to book a Visit. Our primary objective is to examine the feasibility and effectiveness of these interventions. Furthermore, we are evaluating their acceptability and value to key stakeholders and services users. If our approach proves feasible and the risk assessment is both effective and acceptable, we envisage advocating a partnership model of working more broadly to fire and rescue services and health services in Britain, such that effective integration of preventative services for older people becomes routine for an ageing population.

The Inskip Formation, the Harmony Formation, and the Havallah Sequence of Northwestern Nevada - An Interrelated Paleozoic Assemblage in the Home of the Sonoma Orogeny

USGS Publications Warehouse

Ketner, Keith B.

2008-01-01

An area between the towns of Winnemucca and Battle Mountain in northwestern Nevada, termed the arkosic triangle, includes the type areas of the middle to upper Paleozoic Inskip Formation and Havallah sequence, the Upper Devonian to Mississippian Harmony Formation, the Sonoma orogeny, and the Golconda thrust. According to an extensive body of scientific literature, the Havallah sequence, a diverse assemblage of oceanic rocks, was obducted onto the continent during the latest Permian or earliest Triassic Sonoma orogeny by way of the Golconda thrust. This has been the most commonly accepted theory for half a century, often cited but rarely challenged. The tectonic roles of the Inskip and Harmony Formations have remained uncertain, and they have never been fully integrated into the accepted theory. New, and newly interpreted, data are incompatible with the accepted theory and force comprehensive stratigraphic and tectonic concepts that include the Inskip and Harmony Formations as follows: middle to upper Paleozoic strata, including the Inskip, Harmony, and Havallah, form an interrelated assemblage that was deposited in a single basin on an autochthonous sequence of Cambrian, Ordovician, and lowest Silurian strata of the outer miogeocline. Sediments composing the Upper Devonian to Permian sequence entered the basin from both sides, arkosic sands, gravel, limestone olistoliths, and other detrital components entered from the west, and quartz, quartzite, chert, and other clasts from the east. Tectonic activity was expressed as: (1) Devonian uplift and erosion of part of the outer miogeocline; (2) Late Devonian depression of the same area, forming a trough, probably fault-bounded, in which the Inskip, Harmony, and Havallah were deposited; (3) production of intraformational and extrabasinal conglomerates derived from the basinal rocks; and (4) folding or tilting of the east side of the depositional basin in the Pennsylvanian. These middle to upper Paleozoic deposits were compressed in the Jurassic, causing east-verging thrusts in the eastern part of the depositional basin (Golconda thrust) and west-verging thrusts and folds in the western part. Hypotheses involving a far-traveled allochthon that was obducted from an ocean or back-arc basin are incompatible with modern observations and concepts.

2016-01-01

Malnutrition is a frequent finding in pediatric health care settings in the form of undernutrition or excess body weight. Its increasing prevalence and impact on overall health status, which is reflected in the adverse outcomes, renders imperative the application of commonly accepted and evidence-based practices and tools by health care providers. Nutrition risk screening on admission and nutrition status evaluation are key points during clinical management of hospitalized pediatric patients, in order to prevent health deterioration that can lead to serious complications and growth consequences. In addition, anthropometric data based on commonly accepted universal growth standards can give accurate results for nutrition status. Both nutrition risk screening and nutrition status assessment are techniques that should be routinely implemented, based on commonly accepted growth standards and methodology, and linked to clinical outcomes. The aim of the present review was to address the issue of hospital malnutrition in pediatric settings in terms of prevalence, outline nutrition status evaluation and nutrition screening process using different criteria and available tools, and present its relationship with outcome measures. Key teaching points • Malnutrition-underweight or excess body weight-is a frequent imbalance in pediatric settings that affects physical growth and results in undesirable clinical outcomes. • Anthropometry interpretation through growth charts and nutrition screening are cornerstones for the assessment of malnutrition.To date no commonly accepted anthropometric criteria or nutrition screening tools are used in hospitalized pediatric patients. • Commonly accepted nutrition status and screening processes based on the World Health Organization's growth standards can contribute to the overall hospital nutrition care of pediatric patients.

The application of species criteria in avian taxonomy and its implications for the debate over species concepts.

PubMed

Sangster, George

2014-02-01

The debate over species concepts has produced a huge body of literature on how species can, may or should be delimited. By contrast, very few studies have documented how species taxa are delimited in practice. The aims of the present study were to (i) quantify the use of species criteria in taxonomy, (ii) discuss its implications for the debate over species concepts and (iii) assess recent claims about the impact of different species concepts on taxonomic stability and the 'nature' of species. The application of six species criteria was examined in taxonomic studies of birds published between 1950 and 2009. Three types of taxonomic studies were included: descriptions of new species (N = 329), proposals to change the taxonomic rank of species and subspecies (N = 808) and the taxonomic recommendations of the American Ornithologists' Union Committee on Classification and Nomenclature (N = 176). In all three datasets, diagnosability was the most frequently applied criterion, followed by reproductive isolation and degree of difference. This result is inconsistent with the popular notion that the Biological Species Concept is the dominant species concept in avian taxonomy. Since the 1950s, avian species-level taxonomy has become increasingly pluralistic and eclectic. This suggests that taxonomists consider different criteria as complementary rather than as rival approaches to species delimitation. Application of diagnosability more frequently led to the elevation of subspecies to species rank than application of reproductive isolation, although the difference was small. Hypotheses based on diagnosability and reproductive isolation were equally likely to be accepted in a mainstream checklist. These findings contradict recent claims that application of the Phylogenetic Species Concept causes instability and that broader application of the Biological Species Concept can stabilise taxonomy. The criteria diagnosability and monophyly, which are commonly associated with Phylogenetic Species Concepts, were used throughout the study period. Finally, no support was found for the idea that Phylogenetic Species Concepts have caused a change in the 'nature' of species taxa. This study demonstrates that there is a discrepancy between widely held perceptions of how species are delimited and the way species are actually delimited by taxonomists. Theoretically oriented debates over species concepts thus may benefit from empirical data on taxonomic practice. © 2013 The Author. Biological Reviews © 2013 Cambridge Philosophical Society.

Course content is delivered through interactive videos, allowing class time for group work and student-centered activities. We start with simple examples, building complexity throughout the course with the introduction of springs, two dimensions, vectors, energy diagrams, universal gravitation, and rotation. Success means that students ponder underlying physics concepts rather than hunt for formulas. Surveys indicate that students accept this learning model well and have considerable improvement in applied conceptual understanding.

Research that partners with community stakeholders increases contextual relevance and community buy-in and maximizes the chance for intervention success. Within a framework of an academic-community partnership, this project assessed a Black faith-community’s needs and opportunities to address HIV. We used concept mapping to identify/prioritize specific HIV-related strategies that would be acceptable to congregations. Ninety stakeholders brainstormed strategies to address HIV; 21 sorted strategies into groups and rated their importance and feasibility. Multidimensional scaling and cluster analysis were applied to the sorting to produce maps that illustrated the stakeholders’ conceptual thinking about HIV interventions. Of 278 responses, 93 were used in the sorting task. The visual maps represented eight clusters: church acceptance of people living with HIV; education (most feasible); mobilization and communication; church/leaders’ empowerment; church involvement/collaboration; safety/HIV prevention; media outreach; and, stigma (most important). Concept mapping clarified multifaceted issues of HIV in the Black faith community. The results will guide HIV programming in congregations. PMID:28239439

Although organizational context is central to evidence-based practice, underdeveloped measurement hindersitsassessment. The Alberta Context Tool, comprised of 59 items that tap10 modifiable contextual concepts, was developed to address this gap. The purpose of this study to examine the reliability and validity of scores obtained when the Alberta Context Tool is completed by professional nurses across different healthcare settings. Five separate studies (N = 2361 nurses across different care settings) comprised the study sample. Reliability and validity were assessed. Cronbach’s alpha exceeded 0.70 for9/10 Alberta Context Tool concepts. Item-total correlations exceeded acceptable standards for 56/59items. Confirmatory Factor Analysescoordinated acceptably with the Alberta Context Tool’s proposed latent structure. The mean values for each Alberta Context Tool concept increased from low to high levels of research utilization(as hypothesized) further supporting its validity. This study provides robust evidence forreliability and validity of scores obtained with the Alberta Context Tool when administered to professional nurses. PMID:26098857

How does trust affect acceptance of a nuclear power plant (NPP): A survey among people living with Qinshan NPP in China

PubMed Central

Feldman, Marcus W.

2017-01-01

It is difficult to know whether different dimensions of trust have different effects on local residents’ acceptance of nuclear power plants (NPPs). In previous research such trust has been considered as a single dimensional concept. This paper divides trust into goodwill trust and competence trust, and we explore the ways in which trust affects acceptance of NPPs through structural equation modeling. A survey of 491 people was conducted in Haiyan County, China, where the Qinshan nuclear power plant is located. We find that goodwill trust is significantly correlated with competence trust, and each can indirectly promote residents’ acceptance of NPPs but by different paths. Goodwill trust improves acceptance of NPPs by decreasing risk perception, while competence trust improves acceptance of NPPs by increasing benefit perception. However, the associations between goodwill trust and benefit perception, competence trust and risk perception, are not significant. PMID:29176852

At some point in the disease process many persons with dementia (PWD) will have a missing incident and be unable to safely return to their care setting. In previous research studies, researchers have begun to question whether this phenomenon should continue to be called wandering since the antecedents and characteristics of a missing incident are dissimilar to accepted definitions of wandering in dementia. The purpose of this study was to confirm previous findings regarding the antecedents and characteristics of missing incidents, understand the differences between those found dead and alive, and compare the characteristics of a missing incident to that of wandering. A retrospective design was used to analyse 325 newspaper reports of PWD missing in the community. The primary antecedent to a missing incident, particularly in community-dwelling PWD, was becoming lost while conducting a normal and permitted activity alone in the community. The other common antecedent was a lapse in supervision with the expectation that the PWD would remain in a safe location but did not. Deaths most commonly occurred in unpopulated areas due to exposure and drowning. Those who died were found closer to the place last seen and took longer to find, but there were no significant differences in gender or age. The key characteristics of a missing incident were: unpredictable, non-repetitive, temporally appropriate but spatially-disordered, and while using multiple means of movement (walking, car, public transportation). Missing incidents occurred without the discernible pattern present in wandering such as lapping or pacing, repetitive and temporally-disordered. This research supports the mounting evidence that the concept of wandering, in its formal sense, and missing incidents are two distinct concepts. It will be important to further develop the concept of missing incidents by identifying the differences and similarities from wandering. This will allow a more targeted assessment and intervention strategy for each problem.

Acceptance and expressed emotion in Mexican American caregivers of relatives with schizophrenia.

Dorian, Marina; Ramírez García, Jorge I; López, Steven R; Hernández, Brenda

2008-06-01

The relation between Expressed Emotion (EE) and caregiver acceptance was tested with the use of video-recorded interactions between 31 Mexican American family caregivers and their relatives with schizophrenia. Borrowing the concept from Integrative Behavioral Couple Therapy, acceptance was defined as caregiver's engagement with the ill relative along with low levels of expectations for behavioral change. Three aspects of caregiver acceptance were measured: global acceptance of the patient, unified detachment (i.e., nonblaming but engaged problem discussion), and low aversive responses to patient behavior (e.g., criticisms and demanding change). Relative to high EE caregivers, low EE caregivers were consistently more accepting of their ill relatives across the three measures of acceptance. Unified detachment was negatively associated with emotional overinvolvement and aversive responses were positively related to criticism. Warmth was not related to acceptance. The findings suggest that the study of acceptance in family caregivers is a heuristic avenue for future research due to its potential to shed light on specifically what family members do in caring for their ill relatives with schizophrenia.

Background Teaching of health and medical concepts in the K-12 curriculum may help improve health literacy. Purpose The purpose of this project was to determine acceptability and preliminary efficacy of pilot implementation of a health literacy curriculum using brief clips from a popular television program. Methods Participants included 55 ninth-grade students in a low-income school with a high proportion of minority students. The curriculum used three brief interspersed segments from the television show ER to teach basic topics in cardiology. After the 30-minute experimental curriculum, students completed open-ended surveys which were coded qualitatively. Result The most common codes described “enjoyment” (N=28), “acquisition of new knowledge” (N=28), “informative” (N=15), “interesting” (N=12), and “TV/video” (N=10). We found on average 2.9 examples of medical content per participant. Of the 26 spontaneously-generated verifiable statements, 24 (92.3%) were judged as accurate by two independent coders (κ=0.70, P=.0002). Discussion Use of brief segments of video material contributed to the acceptability of health education curricula without detracting from students’ acquisition of accurate information. Translation to Health Education Practice Health education practitioners may wish to include brief clips from popular programming to motivate students and provide context for health-related lessons.

The moral status of the embryo: an attempt at an analysis with the aid of David Hume's ethics.

PubMed

Engel, J B; Hönig, A; Segerer, S; Häusler, S F M; Dietl, J; Djakovic, A

2010-12-01

This article applies the moral sentimentalism founded by David Hume to the moral status of the embryo. It will attempt to explain the paradoxical fact that in Germany abortion is common and socially accepted while preimplantation genetic diagnosis is banned with the aid of an approach based on moral sentimentalism. David Hume established the thesis that the human being is guided by the emotions and not by reason when making moral decisions. Scientific innovations often create a feeling of anxiety. Consequently, the initial moral judgment about it is negative. Due to this habit, the innovation is often accepted after a phase of indifference. This phenomenon has been observed in the case of heart transplantation, as well as for IVF. Consequently, the apparent contradiction in the varying degrees of the embryo's worthiness of protection in the womb and in the Petri dish is due to the simple fact that these are different stages of habituation. Therefore, the ethics of Hume cannot stipulate the embryo's moral status for once and for all; however, they can paradoxically raise the ongoing current debate to a more rational level through the insight that the underlying moral concepts are not based on reason alone.

2007-01-01

We conducted a study to ascertain the acceptability and feasibility of consultation by mobile phone in a rural area of northern India. The mobile phone number of a community physician was advertised to the general public and people were invited to telephone at any time for a medical consultation. Details of the calls received were recorded. During a seven-month study, 660 calls were received. The mean call duration was 2.7 min. Eighty percent of calls were made by men. Forty-eight percent of calls were made during office hours. A total of 417 (63%) calls were for seeking advice, 146 (22%) were for outpatient follow-up, 23 (4%) were for seeking appointments and the remaining 74 (11%) for other reasons. The most common problems were skin, respiratory, mental health and sexual problems. Of the 387 callers who were interviewed at follow-up, 302 (78%) stated that they had followed the advice provided. Of these, 91% found the advice very helpful in managing their health problems. About 96% of users wished to continue to use the service in future. The majority of calls made were of a primary care nature which could easily be dealt with by phone. The concept of using mobile phones for medical consultation seemed to be acceptable to people in rural Haryana.

Work-related cerebro-cardiovascular diseases in Korea.

Cerebro-cardiovascular disease (CVD) is one of compensable occupational diseases in Korea as in Japan or Taiwan. However, most countries accept only cardiovascular diseases (ischemic heart diseases) as compensable occupational diseases if any, but not cerebrovascular diseases. Korea has a prescribed list of compensable occupational diseases. CVD was not included in the list until 1993. In the early 1990s, a case of cerebral infarction was accepted as occupational disease by the Supreme Court. The decision was based on the concept that workers' compensation system is one of the social security systems. In 1994, the government has established a diagnostic criterion of CVD. The crude rate of compensated cerebrovascular disease decreased by 60.0% from 18.5 in 2003 to 7.4 in 2008 per 100,000 workers, and that of compensated coronary heart disease decreased by 60.5% from 3.8 in 2003 to 1.5 in 2008 per 100,000 workers. The compensated cases of CVD dramatically increased and reached its peak in 2003. Since many preventive activities were performed by the government and employers, the compensated cases have slowly decreased since 2003 and sharply decreased after 2008 when the diagnostic criterion was amended. The strategic approach is needed essentially because CVDs are common, serious and preventable diseases which lead to economic burden.

The killing of severely disabled newborns: the spectre behind the legalisation of physician-assisted suicide and euthanasia.

PubMed

Smith, Stephen W

2005-12-01

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.

A novel beam optics concept in a particle therapy gantry utilizing the advantages of superconducting magnets.

PubMed

Gerbershagen, Alexander; Meer, David; Schippers, Jacobus Maarten; Seidel, Mike

2016-09-01

A first order design of the beam optics of a superconducting proton therapy gantry beam is presented. The possibilities of superconducting magnets with respect to the beam optics such as strong fields, large apertures and superposition of different multipole fields have been exploited for novel concepts in a gantry. Since various techniques used in existing gantries have been used in our first design steps, some examples of the existing superconducting gantry designs are described and the necessary requirements of such a gantry are explained. The study of a gantry beam optics design is based on superconducting combined function magnets. The simulations have been performed in first order with the conventional beam transport codes. The superposition of strong dipole and quadrupole fields generated by superconducting magnets enables the introduction of locally achromatic bending sections without increasing the gantry size. A rigorous implementation of such beam optics concepts into the proposed gantry design dramatically increases the momentum acceptance compared to gantries with normal conducting magnets. In our design this large acceptance has been exploited by the implementation of a degrader within the gantry and a potential possibility to use the same magnetic field for all energies used in a treatment, so that the superconducting magnets do not have to vary their fields during a treatment. This also enables very fast beam energy changes, which is beneficial for spreading the Bragg peak over the thickness of the tumor. The results show an improvement of its momentum acceptance. Large momentum acceptance in the gantry creates a possibility to implement faster dose application techniques. Copyright © 2016. Published by Elsevier GmbH.

Exemplary design of a DICOM structured report template for CBIR integration into radiological routine

Welter, Petra; Deserno, Thomas M.; Gülpers, Ralph; Wein, Berthold B.; Grouls, Christoph; Günther, Rolf W.

2010-03-01

The large and continuously growing amount of medical image data demands access methods with regards to content rather than simple text-based queries. The potential benefits of content-based image retrieval (CBIR) systems for computer-aided diagnosis (CAD) are evident and have been approved. Still, CBIR is not a well-established part of daily routine of radiologists. We have already presented a concept of CBIR integration for the radiology workflow in accordance with the Integrating the Healthcare Enterprise (IHE) framework. The retrieval result is composed as a Digital Imaging and Communication in Medicine (DICOM) Structured Reporting (SR) document. The use of DICOM SR provides interchange with PACS archive and image viewer. It offers the possibility of further data mining and automatic interpretation of CBIR results. However, existing standard templates do not address the domain of CBIR. We present a design of a SR template customized for CBIR. Our approach is based on the DICOM standard templates and makes use of the mammography and chest CAD SR templates. Reuse of approved SR sub-trees promises a reliable design which is further adopted to the CBIR domain. We analyze the special CBIR requirements and integrate the new concept of similar images into our template. Our approach also includes the new concept of a set of selected images for defining the processed images for CBIR. A commonly accepted pre-defined template for the presentation and exchange of results in a standardized format promotes the widespread application of CBIR in radiological routine.

Latin American Consensus on the use of transcranial Doppler in the diagnosis of brain death

PubMed Central

2014-01-01

Transcranial Doppler evaluates cerebral hemodynamics in patients with brain injury and is a useful technical tool in diagnosing cerebral circulatory arrest, usually present in the brain-dead patient. This Latin American Consensus was formed by a group of 26 physicians experienced in the use of transcranial Doppler in the context of brain death. The purpose of this agreement was to make recommendations regarding the indications, technique, and interpretation of the study of transcranial ultrasonography in patients with a clinical diagnosis of brain death or in the patient whose clinical diagnosis presents difficulties; a working group was formed to enable further knowledge and to strengthen ties between Latin American physicians working on the same topic. A review of the literature, concepts, and experiences were exchanged in two meetings and via the Internet. Questions about pathophysiology, equipment, techniques, findings, common problems, and the interpretation of transcranial Doppler in the context of brain death were answered. The basic consensus statements are the following: cerebral circulatory arrest is the final stage in the evolution of progressive intracranial hypertension, which is visualized with transcranial Doppler as a "pattern of cerebral circulatory arrest". The following are accepted as the standard of cerebral circulatory arrest: reverberant pattern, systolic spikes, and absence of previously demonstrated flow. Ultrasonography should be used - in acceptable hemodynamic conditions - in the anterior circulation bilaterally (middle cerebral artery) and in the posterior (basilar artery) territory. If no ultrasonographic images are found in any or all of these vessels, their proximal arteries are acceptable to be studied to look for a a pattern of cerebral circulatory arrest. PMID:25295818

Coeliac Disease – New Pathophysiological Findings and Their Implications for Therapy

PubMed Central

Stein, Jürgen; Schuppan, Detlef

2014-01-01

Summary Coeliac disease (CD) is one of the most common diseases worldwide, resulting from a combination of environmental (gluten) and genetic (human leucocyte antigen (HLA) and non-HLA genes) factors. Depending on the geographical location, the prevalence of CD has been estimated to approximate 0.5-1%. The only treatment currently available for CD is a gluten-free diet (GFD) excluding gluten-containing cereals such as wheat, rye, and barley, and other foodstuffs with natural or added gluten. However, adherence rates and patient acceptance are often poor. Moreover, even in fully adherent patients, the diet may fail to induce clinical or histological improvement. Hence, it is unsurprising that studies show CD patients to be highly interested in non-dietary alternatives. The following review focuses on current pathophysiological concepts of CD, spotlighting those pathways which may serve as new possible, non-dietary therapeutic targets in the treatment of CD.

More Than Meets the Eye: Toward a Post-Materialist Model of Consciousness.

Commonly accepted models of human consciousness have substantial shortcomings, in the sense that they cannot account for the entire scope of human experiences. The goal of this article is to describe a model with higher explanatory power, by integrating ideas from psychology and quantum mechanics. In the first part, the need for a paradigm change will be justified by presenting three types of phenomena that challenge the materialistic view of consciousness. The second part is about proposing an alternative view of reality and mind-matter manifestation that is able to accommodate these phenomena. Finally, the ideas from the previous parts will be combined with the psychological concepts developed by Frederic W. H. Myers. The result is a more comprehensive model of human consciousness that offers a novel perspective on altered states of consciousness, genius, and mental health. Copyright © 2016 Elsevier Inc.

Probabilistic confidence for decisions based on uncertain reliability estimates

NASA Astrophysics Data System (ADS)

Reid, Stuart G.

2013-05-01

Reliability assessments are commonly carried out to provide a rational basis for risk-informed decisions concerning the design or maintenance of engineering systems and structures. However, calculated reliabilities and associated probabilities of failure often have significant uncertainties associated with the possible estimation errors relative to the 'true' failure probabilities. For uncertain probabilities of failure, a measure of 'probabilistic confidence' has been proposed to reflect the concern that uncertainty about the true probability of failure could result in a system or structure that is unsafe and could subsequently fail. The paper describes how the concept of probabilistic confidence can be applied to evaluate and appropriately limit the probabilities of failure attributable to particular uncertainties such as design errors that may critically affect the dependability of risk-acceptance decisions. This approach is illustrated with regard to the dependability of structural design processes based on prototype testing with uncertainties attributable to sampling variability.

Target biomarker profile for the clinical management of paracetamol overdose

Vliegenthart, A D Bastiaan; Antoine, Daniel J; Dear, James W

2015-01-01

Paracetamol (acetaminophen) overdose is one of the most common causes of acute liver injury in the Western world. To improve patient care and reduce pressure on already stretched health care providers new biomarkers are needed that identify or exclude liver injury soon after an overdose of paracetamol is ingested. This review highlights the current state of paracetamol poisoning management and how novel biomarkers could improve patient care and save healthcare providers money. Based on the widely used concept of defining a target product profile, a target biomarker profile is proposed that identifies desirable and acceptable key properties for a biomarker in development to enable the improved treatment of this patient population. The current biomarker candidates, with improved hepatic specificity and based on the fundamental mechanistic basis of paracetamol-induced liver injury, are reviewed and their performance compared with our target profile.

Assessing tolerance for wildlife: Clarifying relations between concepts and measures

Bruskotter, Jeremy T.; Singh, Ajay; Fulton, David C.; Slagle, Kristina

2015-01-01

Two parallel lines of inquiry, tolerance for and acceptance of wildlife populations, have arisen in the applied literature on wildlife conservation to assess probability of successfully establishing or increasing populations of controversial species. Neither of these lines is well grounded in social science theory, and diverse measures have been employed to assess tolerance, which inhibits comparability across studies. We empirically tested behavioral measures of tolerance against self-reports of previous policy-relevant behavior and behavioral intentions. Both composite behavioral measures were strongly correlated (r > .70) with two attitudinal measures of tolerance commonly employed in the literature. The strong correlation between attitudinal and behavioral measures suggests existing attitudinal measures represent valid, parsimonious measures of tolerance that may be useful when behavioral measures are too cumbersome or misreporting of behavior is anticipated. Our results demonstrate how behavioral measures of tolerance provide additional, useful information beyond general attitudinal measures.

Automated Subsystem Control for Life Support System (ASCLSS)

Block, Roger F.

1987-01-01

The Automated Subsystem Control for Life Support Systems (ASCLSS) program has successfully developed and demonstrated a generic approach to the automation and control of space station subsystems. The automation system features a hierarchical and distributed real-time control architecture which places maximum controls authority at the lowest or process control level which enhances system autonomy. The ASCLSS demonstration system pioneered many automation and control concepts currently being considered in the space station data management system (DMS). Heavy emphasis is placed on controls hardware and software commonality implemented in accepted standards. The approach demonstrates successfully the application of real-time process and accountability with the subsystem or process developer. The ASCLSS system completely automates a space station subsystem (air revitalization group of the ASCLSS) which moves the crew/operator into a role of supervisory control authority. The ASCLSS program developed over 50 lessons learned which will aide future space station developers in the area of automation and controls..

High-sensitivity green resist material with organic solvent-free spin-coating and tetramethylammonium hydroxide-free water-developable processes for EB and EUV lithography

2015-03-01

We investigated the eco-friendly electron beam (EB) and extreme-ultraviolet (EUV) lithography using a high-sensitive negative type of green resist material derived from biomass to take advantage of organic solvent-free water spin-coating and tetramethylammonium hydroxide(TMAH)-free water-developable techniques. A water developable, non-chemically amplified, high sensitive, and negative tone resist material in EB lithography was developed for environmental affair, safety, easiness of handling, and health of the working people, instead of the common developable process of TMAH. The material design concept to use the water-soluble resist material with acceptable properties such as pillar patterns with less than 100 nm in high EB sensitivity of 10 μC/cm2 and etch selectivity with a silicon-based middle layer in CF4 plasma treatment was demonstrated for EB and EUV lithography.

Most of the systems currently used to analyze astronomical data were designed and implemented more than a decade ago. Although they still are very useful for analysis, one often would like a better interface to newer concepts like archives, Virtual Observatories and GRID. Further, incompatibilities between most of the current systems with respect to control language and semantics make it cumbersome to mix applications from different origins. An OPTICON Network, funded by the Sixth Framework Programme of the European Commission, started this year to discuss high-level needs for an astronomical data analysis environment which could provide a flexible access to both legacy applications and new astronomical resources. The main objective of the Network is to establish widely accepted requirements and basic design recommendations for such an environment. The hope is that this effort will help other projects, which consider to implement such systems, in collaborating and achieving a common environment.

Standards for Environmental Measurement Using GIS: Toward a Protocol for Protocols.

PubMed

Forsyth, Ann; Schmitz, Kathryn H; Oakes, Michael; Zimmerman, Jason; Koepp, Joel

2006-02-01

Interdisciplinary research regarding how the built environment influences physical activity has recently increased. Many research projects conducted jointly by public health and environmental design professionals are using geographic information systems (GIS) to objectively measure the built environment. Numerous methodological issues remain, however, and environmental measurements have not been well documented with accepted, common definitions of valid, reliable variables. This paper proposes how to create and document standardized definitions for measures of environmental variables using GIS with the ultimate goal of developing reliable, valid measures. Inherent problems with software and data that hamper environmental measurement can be offset by protocols combining clear conceptual bases with detailed measurement instructions. Examples demonstrate how protocols can more clearly translate concepts into specific measurement. This paper provides a model for developing protocols to allow high quality comparative research on relationships between the environment and physical activity and other outcomes of public health interest.

Decentralised water systems: emotional influences on resource decision making.

PubMed

Mankad, Aditi

2012-09-01

The study of emotion has gathered momentum in the field of environmental science, specifically in the context of community resource decision-making. Of particular interest in this review is the potential influence of emotion, risk and threat perception on individuals' decisions to acceptance and adopt decentralised water systems, such as rainwater tanks and greywater systems. The role of message framing is also considered in detail, as well as the influences that different types of framing can have on decision making. These factors are considered as possible predictors for analysing community acceptance of decentralised water in urban environments. Concepts believed to be influenced by emotion, such as trust and framing, are also discussed as potentially meaningful contributors to an overall model of community acceptance of decentralised water. Recommendations are made for how emotion-based concepts, such as risk and threat, can be targeted to facilitate widespread adoption of decentralised systems and how researchers can explore different types of emotions that influence decision making in distinct ways. This review is an important theoretical step in advancing the psycho-social understanding of acceptance and adoption of on-site water sources. Avenues for future research are recommended, including the need for greater theoretical development to encourage future social science research on decentralised systems. Crown Copyright © 2012.

Necessary constraints for an equation of state to be physically acceptable

NASA Astrophysics Data System (ADS)

Sheelendra, K.; Vijay, A.

2018-04-01

We have pointed out the constraints required for an equation of state (EOS) to be physically acceptable and universally applicable for the entire range of compressions for a material at high pressures. We have discussed the boundary conditions valid at zero pressure and infinite pressure. The concept of infinite pressure behavior has been discussed. It has been emphasized that the Stacey reciprocal K-primed EOS satisfies all the necessary criterion for the validity of EOS. On the other hand, equations of state reported previously do not satisfy the condition of physical acceptability of an equation of state.

Australians' views on carbon pricing before and after the 2013 federal election

2015-12-01

As climate policies change through the legislative process, public attitudes towards them may change as well. Therefore, it is important to assess how people accept and support controversial climate policies as the policies change over time. Policy acceptance is a positive evaluation of, or attitude towards, an existing policy; policy support adds an active behavioural component. Acceptance does not necessarily lead to support. We conducted a national survey of Australian residents to investigate acceptance of, and support for, the Australian carbon pricing policy before and after the 2013 federal election, and how perceptions of the policy, economic ideology, and voting behaviour affect acceptance and support. We found acceptance and support were stable across the election period, which was surprising given that climate policy was highly contentious during the election. Policy acceptance was higher than policy support at both times and acceptance was a necessary but insufficient condition of support. We conclude that acceptance is an important process through which perceptions of the policy and economic ideology influence support. Therefore, future climate policy research needs to distinguish between acceptance and support to better understand this process, and to better measure these concepts.

Measurement Decision Risk - The Importance of Definitions

NASA Technical Reports Server (NTRS)

Mimbs, Scott M.

2007-01-01

One of the more misunderstood areas of metrology is the Test Uncertainty Ratio (TUR) and its cousin, the Test Accuracy Ratio (TAR). There have been many definitions over the years, but why are these definitions important to a discussion on measurement decision risk? The importance lies in the clarity of communication. Problems can immediately arise in the application (or misapplication) of the definition of these terms. In other words, while it is important to understand the definitions, it is more important to understand concepts behind the definitions and to be precise in how they are applied. The objective of any measurement is a decision. Measurement Decision Risk is a way to look at the quality of a measurement and although it is not a new concept, it has generated a lot of attention since its addition as a requirement in the new U.S. National Standard, ANSI/NCSL Z540.3-2006. In addition to Measurement Decision Risk as the prime method of managing measurement risk, Z540.3 has also added, as a fall-back, an explicit definition for TUR. The impact these changes might have on calibration service providers if these requirements are levied on them has become the topic of much discussion and in some cases concern. This paper looks at the concepts behind the definitions and how they relate to Measurement Decision Risk. Using common examples, this paper will also provide a comparison of various elements of risk related to measurement science using the concepts of TAR, TUR, accuracy ratios, and Consumer Risk (False Accept Risk). The goal is to provide a better understanding of their relevance to the measurement decision process.

Hayden, T. S.; Keller, C. H., Jr.

1973-01-01

High speed helicopter transmission seal concepts were designed, fabricated and tested. The concepts were a dual element split ring seal and a circumferential seal. The tests were performed in a rig using an actual input quill assembly. The test conditions were selected to simulate transmission operation and were 230 F oil temperature, and a sliding speed of 9400 ft/min. The split ring seal exhibited gross leakage and was considered unsatisfactory, while the circumferential seal leakage was less than 1 c.c./hour; this leakage is within acceptable limits. The circumferential seal wear was only to .0005 inches during a 100 hour run (40 starts and stops). During a 40 hour contamination test (mesh silica flour) the seal total wear was a maximum of .004 inches. This wear is considered acceptable.

2018-02-01

Heart failure (HF) is common in older adults. With increases in technology use among older adults, mobile applications may provide a solution for older adults to self-manage symptoms of HF. This article discusses the development and acceptability of a HF symptom-tracking mobile application (HF app). The HF app was developed to allow patients to track their symptoms of HF. Thirty (N = 30) older adults completed an acceptability survey after using the mobile app. The survey used Likert items and open-ended feedback questions. Overall, the acceptability feedback from users was positive with participants indicating that the HF app was both easy to use and understand. Participants identified recommendations for improvement including additional symptoms to track and the inclusion of instructions and reminders. HF is common in older adults, and acceptability of mobile apps is of key importance. The HF app is an acceptable tool for older patients with HF to self-manage their symptoms, identify patterns, and changes in symptoms, and ultimately prevent HF readmission.

Thinking process is a process that begins with the acceptance of information, information processing and information calling in memory with structural changes that include concepts or knowledges. The concept or knowledge is individually constructed by each individual. While, students construct a mathematical concept, students may experience pseudo thinking. Pseudo thinking is a thinking process that results in an answer to a problem or construction to a concept “that is not true”. Pseudo thinking can be classified into two forms there are true pseudo and false pseudo. The construction of mathematical concepts in students of pseudo thinking should be immediately known because the error will have an impact on the next construction of mathematical concepts and to correct the errors it requires knowledge of the source of the error. Therefore, in this article will be discussed thinking process in constructing of mathematical concepts in students who experience pseudo thinking.

Culturally-Competent Treatments for Asian Americans: The Relevance of Mindfulness and Acceptance-Based Psychotherapies

2011-01-01

The development of effective treatments for Asian Americans is important because treatment disparities continue to exist for this population. Because of their theoretical grounding in East Asian philosophies, mindfulness and acceptance-based psychotherapies appear to constitute promising ways to provide culturally responsive mental health care to Asian Americans. However, in practice these approaches often reflect conceptions of mental health that are more consistent with Western world views. We review points of intersection and divergence between Western-based mindfulness and acceptance psychotherapies and Asian American cultural values. We then propose a culturally syntonic approach that accentuates certain components of mindfulness and acceptance psychotherapies and adapts other components of these approaches to be more consistent with Asian American cultural values.

Improving Operational Acceptability of Dynamic Weather Routes Through Analysis of Commonly Use Routings

NASA Technical Reports Server (NTRS)

Evans, Antony D.; Sridhar, Banavar; McNally, David

2016-01-01

The Dynamic Weather Routes (DWR) tool is a ground-based trajectory automation system that continuously and automatically analyzes active in-flight aircraft in en route airspace to find simple modifications to flight plan routes that can save significant flying time, while avoiding weather and considering traffic conflicts, airspace sector congestion, special use airspace, and FAA routing restrictions. Trials of the DWR system have shown that significant delay savings are possible. However, some DWR advised routes are also rejected by dispatchers or modified before being accepted. Similarly, of those sent by dispatchers to flight crews as proposed route change requests, many are not accepted by air traffic control, or are modified before implementation as Center route amendments. Such actions suggest that the operational acceptability of DWR advised route corrections could be improved, which may reduce workload and increase delay savings. This paper analyzes the historical usage of different flight routings, varying from simple waypoint pairs to lengthy strings of waypoints incorporating jet routes, in order to improve DWR route acceptability. An approach is developed that can be incorporated into DWR, advising routings with high historical usage and savings potential similar to that of the nominal DWR advisory. It is hypothesized that modifying a nominal DWR routing to one that is commonly used, and nearby, will result in more actual savings since common routings are generally familiar and operationally acceptable to air traffic control. The approach allows routing segments with high historical usage to be concatenated to form routes that meet all DWR constraints. The relevance of a route's historical usage to its acceptance by dispatchers and air traffic control is quantified by analyzing historical DWR data. Results indicate that while historical usage may be less of a concern to flight dispatchers accepting or rejecting DWR advised route corrections, it may be important to air traffic control acceptance of DWR routes.

Parents Who Decline HPV Vaccination: Who Later Accepts and Why?

Kornides, Melanie L; McRee, Annie-Laurie; Gilkey, Melissa B

2018-03-01

Parental declination contributes to low human papillomavirus (HPV) vaccination coverage among US adolescents, resulting in missed opportunities for cancer prevention. We sought to characterize parents' acceptance of HPV vaccination after declination ("secondary acceptance"). In September 2016, we conducted an online survey with a national sample of parents of children ages 11 to 17 years. For those who reported having ever declined HPV vaccination for their children (n = 494), our survey assessed whether they accepted the vaccine at a subsequent visit. We used multivariable logistic regression to assess correlates of secondary acceptance. Overall, 45% of parents reported secondary acceptance of HPV vaccination, and an additional 24% intended to vaccinate in the next 12 months. In multivariable analyses, secondary acceptance was associated with receiving follow-up counseling about HPV vaccination from a health care provider (odds ratio, 2.16; 95% confidence interval, 1.42-3.28). However, only 53% of parents overall reported receiving such counseling. Secondary acceptance was also associated with receiving a higher quality HPV vaccine recommendation from a provider during the initial discussion and greater satisfaction with provider communication, as well as higher vaccination confidence. Among the reasons for secondary acceptance, parents most commonly reported the child getting older (45%), learning more about HPV vaccine (34%), and receiving a provider recommendation (33%). Our findings suggest secondary acceptance of HPV vaccination is common, with more than two-thirds of parents in this national sample accepting or intending to accept HPV vaccination after declination. Providers should seek to motivate secondary acceptance by delivering repeated, high-quality recommendations for HPV vaccination. Copyright © 2017 Academic Pediatric Association.

Is there a problem with mathematical psychology in the eighteenth century? A fresh look at Kant's old argument.

PubMed

Sturm, Thomas

2006-01-01

Common opinion ascribes to Immanuel Kant the view that psychology cannot become a science properly so called, because it cannot be mathematized. It is equally common to claim that this reflects the state of the art of his times; that the quantification of the mind was not achieved during the eighteenth century, while it was so during the nineteenth century; or that Kant's so-called "impossibility claim" was refuted by nineteenth-century developments, which in turn opened one path for psychology to become properly scientific. These opinions are often connected, but they are misguided nevertheless. In Part I, I show how the issue of a quantification of the mind was discussed before Kant, and I analyze the philosophical considerations both of pessimistic and optimistic authors. This debate reveals a certain progress, although it remains ultimately undecided. In Part II, I present actual examples of measuring the mind in the eighteenth century and analyze their presuppositions. Although these examples are limited in certain ways, the common view that there was no such measurement is wrong. In Part III, I show how Kant's notorious " impossibility claim" has to be viewed against its historical background. He not only accepts actual examples of a quantitative treatment of the mind, but also takes steps toward an explanation of their possibility. Thus, he does not advance the claim that the mind as such cannot be mathematized. His claim is directed against certain philosophical assumptions about the mind, assumptions shared by a then-dominating, strongly introspectionist conception of psychology. This conception did and could not provide an explanation of the possibility of quantifying the mind. In concluding, I reflect on how this case study helps to improve the dispute over when and why psychology became a science. (c) 2006 Wiley Periodicals, Inc.

Women and culture. The case for universal rights.

PubMed

Ruether, R R

1996-01-01

As the movement for women's human rights has become globalized, the charge that feminism is a form of Western cultural imperialism has emerged. An African Anglican priest used this as a response to the author's lecture on Christian feminism and added that "you can't challenge culture." The author responded that since racism could be considered a part of traditional White culture, does this mean that racism can't be challenged. The priest's argument is a common one used by Third World men, Third World women, and First World men to denounce the concept of human rights as women's rights. The Vatican used this argument during recent international conferences to oppose such things as the international approval of family planning and safe abortion, the diversity of notions of family, and an acknowledgement of homosexuality. In UN forums, Islamic nations also argue against women's rights and against the universalization of human rights, which they feel are properly superseded by local cultures. These concepts translated into debates at the Fourth World Conference on Women on topics such as conflicts between religious laws and women's inheritance rights. The culture-human rights argument is also used to defend the practice of female genital mutilation, which is used to control female sexuality in some traditional societies. Western feminist theory must guard against postmodernist critiques of modernity in the name of cultural diversity, since such critiques can make women vulnerable to right-wing male exploitation under premodern patriarchal norms. Classical philosophies of natural law, on the other hand, assume that the cosmos is a whole and that its nature implies ethical norms which govern human well-being. In this tradition, culture is a particular version of the common whole and must constantly be tested against discernment of the universals of human nature in order to be corrected. Feminists must temper their zeal for cultural diversity with an underlying acceptance of this principle of human commonality in order to help women achieve greater justice based on universal human rights.

Association between posttraumatic stress and acceptance of social changes: Findings from a general population study and proposal of a new concept.

There is a growing understanding of the importance of the social factors of posttraumatic stress disorder. This study expands research on association between posttraumatic stress and social factors by introducing the measure of the acceptance of social changes and evaluating possible links between posttraumatic stress disorder symptoms and acceptance of social changes. A general population sample ( n = 778) aged from 18 to 89 years ( M = 40.2) from Lithuania participated in our study, of whom 68% reported exposure to traumatic events. Posttraumatic stress reactions were measured with the Impact of Event Scale - Revised (IES-R), and acceptance of social changes was measured with the Acceptance of Social Changes Instrument (SOCHI) developed by the authors of this study. About 8% of the participants had a potential posttraumatic stress disorder (PTSD) diagnosis. Acceptance of social changes was negatively associated with posttraumatic stress. PTSD was related to lower acceptance of social changes ( d = .61). Structural equation model (SEM) revealed the mediating role of PTSD for acceptance of social changes following trauma exposure. Findings of our study indicate that the acceptance of social changes might be an important psychosocial factor of PTSD.

Trade Study of System Level Ranked Radiation Protection Concepts for Deep Space Exploration

NASA Technical Reports Server (NTRS)

Cerro, Jeffrey A

2013-01-01

A strategic focus area for NASA is to pursue the development of technologies which support exploration in space beyond the current inhabited region of low earth orbit. An unresolved issue for crewed deep space exploration involves limiting crew radiation exposure to below acceptable levels, considering both solar particle events and galactic cosmic ray contributions to dosage. Galactic cosmic ray mitigation is not addressed in this paper, but by addressing credible, easily implemented, and mass efficient solutions for the possibility of solar particle events, additional margin is provided that can be used for cosmic ray dose accumulation. As a result, NASA s Advanced Engineering Systems project office initiated this Radiation Storm Shelter design activity. This paper reports on the first year results of an expected 3 year Storm Shelter study effort which will mature concepts and operational scenarios that protect exploration astronauts from solar particle radiation events. Large trade space definition, candidate concept ranking, and a planned demonstration comprised the majority of FY12 activities. A system key performance parameter is minimization of the required increase in mass needed to provide a safe environment. Total system mass along with operational assessments and other defined protection system metrics provide the guiding metrics to proceed with concept developments. After a downselect to four primary methods, the concepts were analyzed for dosage severity and the amount of shielding mass necessary to bring dosage to acceptable values. Besides analytical assessments, subscale models of several concepts and one full scale concept demonstrator were created. FY12 work terminated with a plan to demonstrate test articles of two selected approaches. The process of arriving at these selections and their current envisioned implementation are presented in this paper.

Is the notion of central fatigue based on a solid foundation?

PubMed

Contessa, Paola; Puleo, Alessio; De Luca, Carlo J

2016-02-01

Exercise-induced muscle fatigue has been shown to be the consequence of peripheral factors that impair muscle fiber contractile mechanisms. Central factors arising within the central nervous system have also been hypothesized to induce muscle fatigue, but no direct empirical evidence that is causally associated to reduction of muscle force-generating capability has yet been reported. We developed a simulation model to investigate whether peripheral factors of muscle fatigue are sufficient to explain the muscle force behavior observed during empirical studies of fatiguing voluntary contractions, which is commonly attributed to central factors. Peripheral factors of muscle fatigue were included in the model as a time-dependent decrease in the amplitude of the motor unit force twitches. Our simulation study indicated that the force behavior commonly attributed to central fatigue could be explained solely by peripheral factors during simulated fatiguing submaximal voluntary contractions. It also revealed important flaws regarding the use of the interpolated twitch response from electrical stimulation of the muscle as a means for assessing central fatigue. Our analysis does not directly refute the concept of central fatigue. However, it raises important concerns about the manner in which it is measured and about the interpretation of the commonly accepted causes of central fatigue and questions the very need for the existence of central fatigue.

“Vaccine hesitancy” is a concept now frequently used in vaccination discourse. The increased popularity of this concept in both academic and public health circles is challenging previously held perspectives that individual vaccination attitudes and behaviours are a simple dichotomy of accept or reject. A consultation study was designed to assess the opinions of experts and health professionals concerning the definition, scope, and causes of vaccine hesitancy in Canada. We sent online surveys to two panels (1- vaccination experts and 2- front-line vaccine providers). Two questionnaires were completed by each panel, with data from the first questionnaire informing the development of questions for the second. Our participants defined vaccine hesitancy as an attitude (doubts, concerns) as well as a behaviour (refusing some / many vaccines, delaying vaccination). Our findings also indicate that both vaccine experts and front-line vaccine providers have the perception that vaccine rates have been declining and consider vaccine hesitancy an important issue to address in Canada. Diffusion of negative information online and lack of knowledge about vaccines were identified as the key causes of vaccine hesitancy by the participants. A common understanding of vaccine hesitancy among researchers, public health experts, policymakers and health care providers will better guide interventions that can more effectively address vaccine hesitancy within Canada.

Wellness Centre: An Evidence-Guided Approach to Delivering Culturally Relevant Community Psychogeriatric Services for Chinese Elders

Chan, Kar C.; Sadavoy, Joel

2012-01-01

Ethnic elders are commonly reluctant to access mental health services and their mental health problems are often overlooked and detected late in the course of illness. Prior studies identified major barriers to ethnic seniors accessing appropriate mental health care demonstrating that language and cultural beliefs cannot be ignored if effective mental health services are to be provided to patients from diverse cultural groups. These are particularly important when care is needed by less acculturated immigrant ethnic seniors for whom language barriers are often greatest. Differences in conceptions of mental distress affect ethnic seniors' choice of help-seeking and often discourage or divert aged persons from utilizing mainstream conventional psychiatric care. Despite the extensive need for appropriate service models for ethnic populations, there have been limited data and models to illustrate how these programs can be systematically and effectively integrated within the mainstream mental health service framework. This paper describes an innovative, mainstream, community-based psychogeriatric service delivery model developed for Chinese seniors in Toronto, Canada, aiming at improving their access to care and enhancing earlier mental health problem detection. The important concepts and strategies of designing and operating a culturally acceptable program are illustrated supported by program data and the challenges analyzed. PMID:23762771

The First International Congress on Ayurveda was held in Milan, Italy in March 2009 and it has been the first scientific event of this kind in western world. This groundbreaking international congress was devoted to human being as the product of interactions between Awareness, Environment and Health, subjects that the West tends to consider separate and independent, but that are believed deeply connected in Ayurveda, whose interdependence defines “The Meaning of Life”. The Congress established a bridge between indian and western philosophy, scientific and biomedical thinking in order to expand knowledge and healthcare. Main attention and address of the invited speakers was on the concept of “relationships” that, connecting living beings with environment, shape Nature itself. This concept is central in Ayurveda but is also common to other western scientific disciplines such as quantum physics and epigenetics that, in the four Sessions of the Congress, were represented by eminent experts. The importance of this event was underlined by the attendance of more than 400 participants and by noteworthy institutional endorsements, that added a significative political dimension of high social impact due to the topical period for CAM acceptance and integration in Europe.

Identification of such population and providing them affordable oral health care is the new concept. A systematic method for identification and screening of persons with mental retardation has been developed and is being followed. Cost and fear are the most commonly cited barriers to dental care. Physical or mental may lead to deterioration in self-care, and oral care state have a low priority. Risk factors are inter-related and are often barriers to oral health. With advancements in today’s world sufficient information and support is available for each and every individual to lead a healthy life which include the access to the oral health care. Factors such as fear, anxiety and dental phobia plays a vital role in acceptance of dental care and also the delaying of dental care. Lack of knowledge of oral and dental disease, awareness or oral need, oral side-effects of medication and organization of dental services are highlighted in the literature. All health personnel should receive training to support the concept of primary oral health care.

Horn, Staccy S

2007-04-01

This study investigated tenth- and twelfth-grade adolescents' (N ≤ 264) judgments about the acceptability of same-sex peers who varied in terms of their sexual orientation (straight, gay or lesbian) and their conformity to gender conventions or norms in regard appearance and mannerisms or activity. Overall, the results of this study suggest that adolescents' conceptions of the acceptability of their peers are related not just to sexual orientation but also conformity to gender conventions. Both straight and gay or lesbian individuals who were non-conventional in their appearance and mannerisms were rated as less acceptable than individuals who conformed to gender conventions or those who participated in non-conventional activities. Most surprisingly, for boys, the straight individual who was non-conforming in appearance was rated less acceptable than either the gay individual who conformed to gender norms or was gender non-conforming in choice of activity.

A series of combustor pressure rig screening tests was conducted on three combustor concepts applied to the TFE731-2 turbofan engine combustion system for the purpose of evaluating their relative emissions reduction potential consistent with prescribed performance, durability, and envelope contraints. The three concepts and their modifications represented increasing potential for reducing emission levels with the penalty of increased hardware complexity and operational risk. Concept 1 entailed advanced modifications to the present production TFE731-2 combustion system. Concept 2 was based on the incorporation of an axial air-assisted airblast fuel injection system. Concept 3 was a staged premix/prevaporizing combustion system. Significant emissions reductions were achieved in all three concepts, consistent with acceptable combustion system performance. Concepts 2 and 3 were identified as having the greatest achievable emissions reduction potential, and were selected to undergo refinement to prepare for ultimate incorporation within an engine.

2012-01-01

Self-concept and ego development, two intertwined aspects of self-indicating well-being and social-cognitive maturation, respectively, were examined in a representative sample of deaf adolescents of normal intelligence (N = 68), using translated and adapted versions of Harter's (1988, Manual for the self-perception profile for adolescents. Denver, CO: University of Denver) multidimensional measure of self-concept and Loevinger's (1998, Technical foundations for measuring ego development. Mahwah, NJ: Lawrence Erlbaum) measure of ego development. Compared to hearing norm groups, deaf adolescents showed lower levels of self-perceived social acceptance, close friendships and ego development and higher physical appearance. Hierarchical multiple regression analyses controlling for sociodemographic variables showed positive associations of global self-worth with support for signing during childhood and quality of parent-child communication and of ego development with attending a regular school. Cluster analysis identified three social competence profiles: uniformly low competence, uniformly high competence, and low social acceptance with high physical appearance. Cluster membership was associated with school type, ego development, and (past) neurological disorder. The results are discussed in reference to interventions aimed at the well-being of deaf youth.

Student evaluation of problem-based learning in a dental orthodontic curriculum--a pilot study.

The present questionnaire survey investigated student reception of problem-based learning (PBL) in the orthodontic curriculum with regard to acceptance, sense of purpose and motivation, knowledge and understanding, as well as tutorial support. Over a period of two terms, we compared two different didactic methods (PBL and short presentations) by randomizing the participants of a course on orthodontic diagnostics into two different groups, who inversed methods after the first term. The two student groups did not show any significant differences with regard to assessments or examination performance. Therefore, acceptance of the PBL concept seems to be mainly associated with the motivation of individuals to use this method. The higher the motivation, the more positive is the attitude towards the PBL concept. Students seem to work more constructively and efficiently with PBL if they can judge the concept meaningful for themselves. In consideration of the relevant literature and the present results, PBL can be principally integrated into the dental curriculum as a method of learning. However, student motivation is vital to learning success.

Exploring one aspect of pedagogical content knowledge of teaching assistants using the Conceptual Survey of Electricity and Magnetism

Karim, Nafis I.; Maries, Alexandru; Singh, Chandralekha

2018-06-01

The Conceptual Survey of Electricity and Magnetism (CSEM) has been used to assess student understanding of introductory concepts of electricity and magnetism because many of the items on the CSEM have strong distractor choices which correspond to students' alternate conceptions. Instruction is unlikely to be effective if instructors do not know the common alternate conceptions of introductory physics students and explicitly take into account common student difficulties in their instructional design. Here, we discuss research involving the CSEM to evaluate one aspect of the pedagogical content knowledge of teaching assistants (TAs): knowledge of introductory students' alternate conceptions in electricity and magnetism as revealed by the CSEM. For each item on the CSEM, the TAs were asked to identify the most common incorrect answer choice selected by introductory physics students if they did not know the correct answer after traditional instruction. Then, we used introductory student CSEM post-test data to assess the extent to which TAs were able to identify the most common alternate conception of introductory students in each question on the CSEM. We find that the TAs were thoughtful when attempting to identify common student difficulties and they enjoyed learning about student difficulties this way. However, they struggled to identify many common difficulties of introductory students that persist after traditional instruction. We discuss specific alternate conceptions that persist after traditional instruction, the extent to which TAs were able to identify them, and results from think-aloud interviews with TAs which provided valuable information regarding why the TAs sometimes selected certain alternate conceptions as the most common but were instead very rare among introductory students. We also discuss how tasks such as the one used in this study can be used in professional development programs to engender productive discussions about the importance of being knowledgeable about student alternate conceptions in order to help students learn. Interviews with TAs engaged in this task as well as our experience with such tasks in our professional development programs suggest that they are beneficial.

Bioethics of life programs: taking seriously moral pluralism in clinical settings.

PubMed

Niebroj, Leslaw

2010-11-04

In the more and more globalized world, the experience of moral pluralism (often related to, or based upon, religious pluralism) has become a common issue which ethical importance is undeniable. Potential conflicts between patients' and therapeutic teams' moral views and between moral beliefs of the particular member of this team are being resolved in the light of bioethical theories, among which principlism remains the mainstream approach to biomedical ethics. The question arises, however, whether this approach, in itself, as being strictly bound to the specific and distinct American philosophical tradition, is to be considered the tool for so called ?moral imperialism'. Also architectures of principlism, in particular by elaborating the concept of common morality, defend the applicability of their theory to the pluralistic settings, it should be emphasized that the idea that some norms and standards of moral character are shared by all morally serious people in every culture has attracted criticism both from empirical as well as theoretical backgrounds. This paper aims at reconsidering principlism so that it would be more suitable for resolving moral dilemma in ethically pluralistic clinical settings. Lakatos' sophisticated methodological falsification is used into two different ways: (1) to construct a concept of 'life programs' and (2) to confront a newly elaborated ethical theory with principlism. The reflection is limited to the norms related to the key issue in clinical ethics, i.e., respecting the patient's autonomy. The concepts of common morality and particular moralities are interpreted (in the light of Lakatos' philosophy of sciences) as "hard core" and "protective belt" of life programs, respectively. Accepting diversity of research programs, Lakatos maintains the idea of the objectivity of truth. Analogously, the plurality of life programs does not put into question the objectivity of moral values. The plurality of moral norms not only respects the objectivity of the good, but also can be seen as a condition sine qua non of such objectivity in the changing socio-historical context of doctor-patient relationship. The life program approach to bioethics and clinical ethics in particular, can be seen as a form of widening of principlism. This new approach, being non-relativistic, is at the same time sensitive to moral pluralism experienced in everyday medical practice.

Human attribute concepts: relative ubiquity across twelve mutually isolated languages.

It has been unclear which human-attribute concepts are most universal across languages. To identify common-denominator concepts, we used dictionaries for 12 mutually isolated languages-Maasai, Supyire Senoufo, Khoekhoe, Afar, Mara Chin, Hmong, Wik-Mungkan, Enga, Fijian, Inuktitut, Hopi, and Kuna-representing diverse cultural characteristics and language families, from multiple continents. A composite list of every person-descriptive term in each lexicon was closely examined to determine the content (in terms of English translation) most ubiquitous across languages. Study 1 identified 28 single-word concepts used to describe persons in all 12 languages, as well as 41 additional terms found in 11 of 12. Results indicated that attribute concepts related to morality and competence appear to be as cross-culturally ubiquitous as basic-emotion concepts. Formulations of universal-attribute concepts from Osgood and Wierzbicka were well-supported. Study 2 compared lexically based personality models on the relative ubiquity of key associated terms, finding that 1- and 2-dimensional models draw on markedly more ubiquitous terms than do 5- or 6-factor models. We suggest that ubiquitous attributes reflect common cultural as well as common biological processes.

Is prostitution harmful?

PubMed

Moen, Ole Martin

2014-02-01

A common argument against prostitution states that selling sex is harmful because it involves selling something deeply personal and emotional. More and more of us, however, believe that sexual encounters need not be deeply personal and emotional in order to be acceptable--we believe in the acceptability of casual sex. In this paper I argue that if casual sex is acceptable, then we have few or no reasons to reject prostitution. I do so by first examining nine influential arguments to the contrary. These arguments purport to pin down the alleged additional harm brought about by prostitution (compared to just casual sex) by appealing to various aspects of its practice, such as its psychology, physiology, economics and social meaning. For each argument I explain why it is unconvincing. I then weight the costs against the benefits of prostitution, and argue that, in sum, prostitution is no more harmful than a long line of occupations that we commonly accept without hesitation.

Redesign of solid rocket booster/external tank attachment ring for the space transportation system

1987-01-01

An improved design concept is presented for the Space Shuttle solid rocket booster (SRB)/external tank (ET) attachment ring structural component. This component picks up three struts which attach the aft end of each SRB to the ET. The concept is a partial ring with carefully tapered ends to distribute fastener loads safely into the SRB. Extensive design studies and analyses were performed to arrive at the concept. Experiments on structural elements were performed to determine material strength and stiffness characteristics. Materials and fabrication studies were conducted to determine acceptable tolerances for the design concept. An overview is provided of the work along with conclusions and major recommendations.

Meantime, it is well accepted that hyperforin, the chemical instable phloroglucinol derivative of Hypericum perforatum, St. John's wort, is the pharmacophore of St. John's wort extracts. With the decline of this scientific discussion, another controversial aspect has been arisen, the question regarding the underlying mechanism leading to the pharmacological profile of the plant extract used in therapy of depression. We will summarize the different concepts described for hyperforin's antidepressive activity. Starting with unspecific protein-independent mechanisms due to changes in pH, we will summarize data of protein-based concepts beginning with concepts based on involvement of a variety of proteins and will finally present concepts based on the modulation of a single protein.

Retaining residual newborn screening (NBS) bloodspots for medical research remains contentious. To inform this debate, we sought to understand public preferences for, and reasons for preferring, alternative policy options. We assessed preferences among 4 policy options for research use of residual bloodspots through a bilingual national Internet survey of a representative sample of Canadians. Fifty percent of respondents were randomly assigned to select reasons supporting these preferences. Understanding of and attitudes toward screening and research concepts, and demographics were assessed. Of 1102 respondents (94% participation rate; 47% completion rate), the overall preference among policy options was ask permission (67%); this option was also the most acceptable choice (80%). Assume permission was acceptable to 46%, no permission required was acceptable to 29%, and no research allowed was acceptable to 26%. The acceptability of the ask permission option was reduced among participants assigned to the reasoning exercise (84% vs 76%; P = .004). Compared with assume/no permission required, ordered logistic regression showed a significant reduction in preference for the ask permission option with greater understanding of concepts (odds ratio, 0.87; P < .001), greater confidence in science (odds ratio, 0.16; P < .001), and a perceived responsibility to contribute to research (odds ratio, 0.39; P < .001). Surveyed Canadians prefer that explicit permission is sought for storage and research use of NBS bloodspots. This preference was diminished when reasons supporting and opposing routine storage, and other policy options, were presented. Findings warrant consideration as NBS communities strategize to respond to shifting legislative contexts. Copyright © 2016 by the American Academy of Pediatrics.

High acceptance rate of hybrid allogeneic-autologous umbilical cord blood banking among actual and potential Swiss donors.

2013-07-01

Two competitive concepts of umbilical cord blood (UCB) banking are currently available: either allogeneic UCB is donated to a public bank or autologous cells are stored in a private bank. Allogeneic-autologous hybrid banking is a new concept that combines these two approaches. However, acceptance of hybrid UCB banking among potential donors is unknown to date. In a prospective survey, we aimed to establish the acceptance of the hybrid banking model among actual and potential UCB donors in Switzerland. The study groups consisted of parents and pregnant women with or without children. As control group, women at reproductive ages were investigated. The majority of participants agreed fundamentally with UCB donation, and overall acceptance of private banking was 47%. If a possibility for hybrid banking were to be made available, 49% would opt for such a public-private model and only 13% would choose private banking alone. Among the proponents of hybrid banking, a majority of participants chose donor cell splitting over the sequential banking mode. Fifty-six percent of responders wished prior notification before the release of their donated UCB to a foreign recipient. This is the first study which compared the acceptance of allogeneic, autologous, and hybrid allogeneic-autologous UCB banking in different target groups. We demonstrated that hybrid cord blood banking is the preferred model of banking among actual and potential UCB donors. With increasing demand for UCB in the future, health care providers should therefore consider offering hybrid banking as a viable storage option. © 2012 American Association of Blood Banks.

Buddhism at Crossroads: A Case Study of Six Tibetan Buddhist Monks Navigating the Intersection of Buddhist Theology and Western Science

NASA Astrophysics Data System (ADS)

Sonam, Tenzin

Recent effort to teach Western science in the Tibetan Buddhist monasteries has drawn interest both within and outside the quarters of these monasteries. This novel and historic move of bringing Western science in a traditional monastic community began around year 2000 at the behest of His Holiness the Dalai Lama, the spiritual head of Tibetan Buddhism. Despite the novelty of this effort, the literature in science education about learners from non-Western communities suggests various "cognitive conflicts" experienced by these non-Western learners due to fundamental difference in the worldview of the two knowledge traditions. Hence, in this research focuses on how six Tibetan Buddhist monks were situating/reconciling the scientific concepts like the theory of evolution into their traditional Buddhist worldview. The monks who participated in this study were engaged in a further study science at a university in the U.S. for two years. Using case study approach, the participants were interviewed individually and in groups over the two-year period. The findings revealed that although the monks scored highly on their acceptance of evolution on the Measurement of Acceptance of Theory of Evolution (MATE) survey, however in the follow-up individual and focus group interviews, certain conflicts as well as agreement between the theory of evolution and their Buddhist beliefs were revealed. The monks experienced conflicts over concepts within evolution such as common ancestry, human evolution, and origin of life, and in reconciling the Buddhist and scientific notion of life. The conflicts were analyzed using the theory of collateral learning and was found that the monks engaged in different kinds of collateral learning, which is the degree of interaction and resolution of conflicting schemas. The different collateral learning of the monks was correlated to the concepts within evolution and has no correlation to the monks' years in secular school, science learning or their proficiency of English language. This study has indicted that the Tibetan Buddhist monks also experience certain cognitive conflict when situating Western scientific concepts into their Buddhist worldview as suggested by research of science learners from other non-Western societies. By explicating how the monks make sense of scientific theories like the theory of evolution as an exemplar, I hope to inform the current effort to establish science education in the monastery to develop curricula that would result in meaningful science teaching and learning, and also sensitive to needs and the cultural survival of the monastics.

Cruise-Efficient Short Takeoff and Landing (CESTOL): Potential Impact on Air Traffic Operations

NASA Technical Reports Server (NTRS)

Couluris, G. J.; Signor, D.; Phillips, J.

2010-01-01

The National Aeronautics and Space Administration (NASA) is investigating technological and operational concepts for introducing Cruise-Efficient Short Takeoff and Landing (CESTOL) aircraft into a future US National Airspace System (NAS) civil aviation environment. CESTOL is an aircraft design concept for future use to increase capacity and reduce emissions. CESTOL provides very flexible takeoff, climb, descent and landing performance capabilities and a high-speed cruise capability. In support of NASA, this study is a preliminary examination of the potential operational impact of CESTOL on airport and airspace capacity and delay. The study examines operational impacts at a subject site, Newark Liberty Intemational Airport (KEWR), New Jersey. The study extends these KEWR results to estimate potential impacts on NAS-wide network traffic operations due to the introduction of CESTOL at selected major airports. These are the 34 domestic airports identified in the Federal Aviation Administration's Operational Evolution Plan (OEP). The analysis process uses two fast-time simulation tools to separately model local and NAS-wide air traffic operations using predicted flight schedules for a 24-hour study period in 2016. These tools are the Sen sis AvTerminal model and NASA's Airspace Concept Evaluation System (ACES). We use both to simulate conventional-aircraft-only and CESTOL-mixed-with-conventional-aircraft operations. Both tools apply 4-dimension trajectory modeling to simulate individual flight movement. The study applies AvTerminal to model traffic operations and procedures for en route and terminal arrival and departures to and from KEWR. These AvTerminal applications model existing arrival and departure routes and profiles and runway use configurations, with the assumption jet-powered, large-sized civil CESTOL aircraft use a short runway and standard turboprop arrival and departure procedures. With these rules, the conventional jet and CESTOL aircraft are procedurally separated from each other geographically and in altitude during tenninal airspace approach and departure operations, and each use a different arrival runway. AvTeminal implements its unique Focal-point Scheduling Process to sequence, space and delay aircraft to resolve spacing and overtake conflicts among flights in the airspace and airport system serving KEWR. This Process effectively models integrated arrival and departure operations. AvTerminal assesses acceptance rates and delay magnitude and causality at selected locations, including en route outer boundary fixes, tenninal airspace arrival and departure boundary fixes, terminal airspace arrival merge and departure diverge fixes, and runway landing and takeoff runways. The analysis compares the resulting capacity impacts, flight delays and delay sources between CESTOL and conventional KEWR operations. AvTerminal quantitative results showed that CESTOL has significant capability to increase airport arrival acceptance rates (35-40% at KEWR) by taking advantage of otherwise underused airspace and runways where available. The study extrapolates the AvTerminal-derived KEWR peak arrival and departure acceptance rates to estimate capacity parameter values for each of the OEP airports in the ACES modeling of traffic through the entire NAS network. The extrapolations of acceptance rates allow full, partial or no achievement of CESTOL capacity gains at an OEP airport as determined by assessments of the degree to which local procedures allow leveraging of CESTOL capabilities. These assessments consider each OEP airport's runway geometries, runway system configurations, airport and airspace operations, and potential CESTOL traffic loadings. The ACES modeling, simulates airport and airspace spacing constraints imposed by airport runway system, terminal and en route air traffic control and traffic flow management operations using airport acceptance rates representing conventional-aircraft-only and CESTOL-mixed operations. CEOL aircraft are assumed to have Mach 0.8, and alternatively Mach 0.7, cruise speeds to examine compatibility with conventional aircraft operations in common airspace. The ACES results provides estimates of CESTOL delay impact NAS-wide and at OEP airports due to changes in OEP airport acceptance rates and changes in en route airspace potential conflict rates. Preliminary results show meaningful nationwide delay reductions (20%) due to CESTOL operations at 34 major domestic airports.

Envisioning the inner body during the Edo period in Japan: Inshoku yojo kagami (Rules of Dietary Life) and Boji yojo kagami (Rules of Sexual Life).

PubMed

Shirasugi, Etsuo

2007-03-01

There are two ukiyoe, Japanese woodblock prints, that were produced around 1850 and give a good picture of the images of the insides of the human body that were widely accepted among the common people in the Edo period. The Inshoku yojo kagami (Rules of Dietary Life) shows a man drinking sake. The Boji yojo kagami (Rules of Sexual Life) shows a woman, apparently a courtesan. The purpose of the two ukiyoe was to educate viewers about the functions of the principal inner organs in the traditional East Asian concept of the body and to admonish them against excessive eating, drinking and sexual intercourse. The contrivance of the two ukiyoe lies in their fusion of two formats. One is the format of a see-through body displaying the internal organs. The other is that of explaining the functions of the various internal organs in the form of familiar scenes from the living space of cities and households. Miniature sketches can be seen in the prints of people at work, performing the tasks believed to be that of each organ. However, the scheme of the two ukiyoe was not an innovation of the author of the ukioye. Already in the kibyoshi (Yellow Cover booklets), the scheme of likening the interior of the body to a living space had been adopted. After entering the 18th century, Chinese medical knowledge and anatomical drawings became available. As sex manuals, Yellow Cover booklets, and ukiyoe publications, incorporated and disseminated the newly acquired medical knowledge and the medical concept of the body gradually became the common sense view among people in the street.

Radiative transfer modelling (RTM) is an indispensable tool for a number of applications, including astrophysics, climate studies and quantitative remote sensing. It simulates the attenuation of light through a translucent medium. Here, we look at the scattering and absorption of solar light on its way to the Earth's surface and back to space or back into a remote sensing instrument. RTM is regularly used in the framework of the so-called atmospheric correction to find properties of the surface. Further, RTM can be inverted to retrieve features of the atmosphere, such as the aerosol optical depth (AOD), for instance. Present-day RTM, such as 6S, MODTRAN, SHARM, RT3, SCIATRAN or RTMOM have errors of only a few percent, however they are rather slow and often not easy to use. We present here a concept for a fast and simple RTM model in the visible spectral range. It is using a blend of different existing RTM approaches with a special emphasis on fast approximative analytical equations and parametrizations. This concept may be helpful for efficient retrieval algorithms, which do not have to rely on the classic look-up-tables (LUT) approach. For example, it can be used to retrieve AOD without complex inversion procedures including multiple iterations. Naturally, there is always a trade-off between speed and modelling accuracy. The code can be run therefore in two different modes. The regular mode provides a reasonable ratio between speed and accuracy, while the optional mode is very fast but less accurate. The normal mode approximates the diffuse scattered light by calculating the first (single scattering) and second order of scattering according to the classical method of successive orders of scattering. The very fast mode calculates only the single scattering approximation, which does not need any slow numerical integration procedure, and uses a simple correction factor to account for multiple scattering. This factor is a parametrization of MODTRAN results, which provide a typical ratio between single and multiple scattered light. A comparison of the presented RTM concept to the widely accepted 6S RTM reveals errors of up to 10% in standard mode. This is acceptable for certain applications. The very fast mode may lead to errors of up to 30%, but it is still able to reproduce qualitatively the results of 6S. An experimental implementation of this RTM concept is written in the common IDL language. It is therefore very flexible and straightforward to be implemented into custom retrieval algorithms of the remote sensing community. The code might also be used to add an atmosphere on top of an existing vegetation-canopy or water RTM. Due to the ease of use of the RTM code and the comprehensibility of the internal equations, the concept might be useful for educational purposes as well. The very fast mode could be of interest for a real-time applications, such as an in-flight instrument performance check for airborne optical sensors. In the future, the concept can be extended to account for scattering according to Mie theory, polarization and gaseous absorption. It is expected that this would reduce the model error to 5% or less.

Summary This investigation explored commonalities and differences in barriers and motivators to HIV vaccine trial participation and acceptability of future U.S. Food and Drug Administration (FDA)-approved HIV vaccines in order to identify implications of clinical trials for future HIV vaccine dissemination. Fifteen focus groups were conducted with 157 predominately ethnic minority and low income participants recruited using venue-based sampling in Los Angeles. Data were analyzed using narrative thematic analysis. Barriers and motivators in common across willingness to participate (WTP) in HIV vaccine trials and future HIV vaccine acceptability (e.g., concerns about vaccine-induced infection, false-positives, side effects, efficacy, mistrust and stigma) suggest clinical trials present significant opportunities to develop and evaluate empirically based interventions to support future HIV vaccine dissemination. Barriers specific to HIV vaccine acceptability (e.g., concerns about duration of protection, cross-clade protection, cost and access) also indicate the need for formative research focused specifically on future dissemination. Protection motivation, common to WTP and acceptability, highlights the need to provide and evaluate prevention counseling and education in clinical trials, which may form the basis of evidence-informed preventive interventions to be launched in tandem with dissemination of partial efficacy HIV vaccines.

The concept of J wave syndromes was first proposed in 2004 by Yan et al for a spectrum of electrocardiographic (ECG) manifestations of prominent J waves that are associated with a potential to predispose affected individuals to ventricular fibrillation (VF). Although the concept of J wave syndromes is widely used and accepted, there has been tremendous debate over the definition of J wave, its ionic and cellular basis and arrhythmogenic mechanism. In this review article, we attempted to discuss the history from which the concept of J wave syndromes (JWS) is evolved and current controversies in JWS. PMID:27721848

The final common module set exhibiting wide commonality is described. The set consists of three types of modules: one free flying module and two modules that operate attached to the space station. The common module designs provide for the experiment program as defined. The feasibility, economy, and practicality of these modules hinges on factors that do not affect the approach or results of the commonality process, but are important to the validity of the common module concepts. Implementation of the total experiment program requires thirteen common modules: five CM-1, five CM-3, and three CM-4 modules.

Technical note: Alternatives to reduce adipose tissue sampling bias.

PubMed

Cruz, G D; Wang, Y; Fadel, J G

2014-10-01

Understanding the mechanisms by which nutritional and pharmaceutical factors can manipulate adipose tissue growth and development in production animals has direct and indirect effects in the profitability of an enterprise. Adipocyte cellularity (number and size) is a key biological response that is commonly measured in animal science research. The variability and sampling of adipocyte cellularity within a muscle has been addressed in previous studies, but no attempt to critically investigate these issues has been proposed in the literature. The present study evaluated 2 sampling techniques (random and systematic) in an attempt to minimize sampling bias and to determine the minimum number of samples from 1 to 15 needed to represent the overall adipose tissue in the muscle. Both sampling procedures were applied on adipose tissue samples dissected from 30 longissimus muscles from cattle finished either on grass or grain. Briefly, adipose tissue samples were fixed with osmium tetroxide, and size and number of adipocytes were determined by a Coulter Counter. These results were then fit in a finite mixture model to obtain distribution parameters of each sample. To evaluate the benefits of increasing number of samples and the advantage of the new sampling technique, the concept of acceptance ratio was used; simply stated, the higher the acceptance ratio, the better the representation of the overall population. As expected, a great improvement on the estimation of the overall adipocyte cellularity parameters was observed using both sampling techniques when sample size number increased from 1 to 15 samples, considering both techniques' acceptance ratio increased from approximately 3 to 25%. When comparing sampling techniques, the systematic procedure slightly improved parameters estimation. The results suggest that more detailed research using other sampling techniques may provide better estimates for minimum sampling.

Dealing with Uncertainty and Accounting for Social Value Judgments in Assessments of Orphan Drugs: Evidence from Four European Countries.

Nicod, Elena; Berg Brigham, Karen; Durand-Zaleski, Isabelle; Kanavos, Panos

To better understand the reasons for differences in reimbursement decisions for orphan drugs in four European countries that were not readily apparent from health technology assessment (HTA) reports and operating procedures. Semistructured interviews with representatives of HTA bodies in England, Scotland, Sweden, and France were conducted. An interview topic guide was developed on the basis of findings from a systematic comparison of HTA decisions for 10 orphan drugs. Qualitative thematic data analysis was applied to the interview transcripts using the framework approach. Eight representatives from the four HTA bodies were interviewed between March and June 2015. Evidentiary requirements and approaches to dealing with imperfect or incomplete evidence were explored, including trial design and duration, study population and subgroups, comparators, and end points. Interviewees agreed that decisions regarding orphan drugs are made in a context of lower quality evidence, and the threshold of acceptable uncertainty varied by country. Some countries imposed higher evidentiary standards for greater clinical claims, which may be more challenging for orphan diseases. The acceptability of surrogate end points was not consistent across countries nor were the validation requirements. The most common social value judgments identified related to innovation, disease severity, and unmet need. Differences were seen in the way these concepts were defined and accounted for across countries. Although agreement was seen in evidentiary requirements or preferences, there were subtle differences in the circumstances in which uncertain evidence may be considered acceptable, possibly explaining differences in HTA recommendations across countries.

Can Fire and Rescue Services and the National Health Service work together to improve the safety and wellbeing of vulnerable older people? Design of a proof of concept study

PubMed Central

2010-01-01

Background Older adults are at increased risk both of falling and of experiencing accidental domestic fire. In addition to advanced age, these adverse events share the risk factors of balance or mobility problems, cognitive impairment and socioeconomic deprivation. For both events, the consequences include significant injury and death, and considerable socioeconomic costs for the individual and informal carers, as well as for emergency services, health and social care agencies. Secondary prevention services for older people who have fallen or who are identifiable as being at high risk of falling include NHS Falls clinics, where a multidisciplinary team offers an individualised multifactorial targeted intervention including strength and balance exercise programmes, medication changes and home hazard modification. A similar preventative approach is employed by most Fire and Rescue Services who conduct Home Fire Safety Visits to assess and, if necessary, remedy domestic fire risk, fit free smoke alarms with instruction for use and maintenance, and plan an escape route. We propose that the similarity of population at risk, location, specific risk factors and the commonality of preventative approaches employed could offer net gains in terms of feasibility, effectiveness and acceptability if activities within these two preventative approaches were to be combined. Methods/Design This prospective proof of concept study, currently being conducted in two London boroughs, (Southwark and Lambeth) aims to reduce the incidence of both fires and falls in community-dwelling older adults. It comprises two concurrent 12-month interventions: the integration of 1) fall risk assessments into the Brigade's Home Fire Safety Visit and 2) fire risk assessments into Falls services by inviting older clinic attendees to book a Visit. Our primary objective is to examine the feasibility and effectiveness of these interventions. Furthermore, we are evaluating their acceptability and value to key stakeholders and services users. Discussion If our approach proves feasible and the risk assessment is both effective and acceptable, we envisage advocating a partnership model of working more broadly to fire and rescue services and health services in Britain, such that effective integration of preventative services for older people becomes routine for an ageing population.

The Processing of Airspace Concept Evaluations Using FASTE-CNS as a Pre- or Post-Simulation CNS Analysis Tool

NASA Technical Reports Server (NTRS)

Mainger, Steve

2004-01-01

As NASA speculates on and explores the future of aviation, the technological and physical aspects of our environment increasing become hurdles that must be overcome for success. Research into methods for overcoming some of these selected hurdles have been purposed by several NASA research partners as concepts. The task of establishing a common evaluation environment was placed on NASA's Virtual Airspace Simulation Technologies (VAST) project (sub-project of VAMS), and they responded with the development of the Airspace Concept Evaluation System (ACES). As one examines the ACES environment from a communication, navigation or surveillance (CNS) perspective, the simulation parameters are built with assumed perfection in the transactions associated with CNS. To truly evaluate these concepts in a realistic sense, the contributions/effects of CNS must be part of the ACES. NASA Glenn Research Center (GRC) has supported the Virtual Airspace Modeling and Simulation (VAMS) project through the continued development of CNS models and analysis capabilities which supports the ACES environment. NASA GRC initiated the development a communications traffic loading analysis tool, called the Future Aeronautical Sub-network Traffic Emulator for Communications, Navigation and Surveillance (FASTE-CNS), as part of this support. This tool allows for forecasting of communications load with the understanding that, there is no single, common source for loading models used to evaluate the existing and planned communications channels; and that, consensus and accuracy in the traffic load models is a very important input to the decisions being made on the acceptability of communication techniques used to fulfill the aeronautical requirements. Leveraging off the existing capabilities of the FASTE-CNS tool, GRC has called for FASTE-CNS to have the functionality to pre- and post-process the simulation runs of ACES to report on instances when traffic density, frequency congestion or aircraft spacing/distance violations have occurred. The integration of these functions require that the CNS models used to characterize these avionic system be of higher fidelity and better consistency then is present in FASTE-CNS system. This presentation will explore the capabilities of FASTE-CNS with renewed emphasis on the enhancements being added to perform these processing functions; the fidelity and reliability of CNS models necessary to make the enhancements work; and the benchmarking of FASTE-CNS results to improve confidence for the results of the new processing capabilities.

Conceptual Structure within and between Modalities

Dilkina, Katia; Lambon Ralph, Matthew A.

2012-01-01

Current views of semantic memory share the assumption that conceptual representations are based on multimodal experience, which activates distinct modality-specific brain regions. This proposition is widely accepted, yet little is known about how each modality contributes to conceptual knowledge and how the structure of this contribution varies across these multiple information sources. We used verbal feature lists, features from drawings, and verbal co-occurrence statistics from latent semantic analysis to examine the informational structure in four domains of knowledge: perceptual, functional, encyclopedic, and verbal. The goals of the analysis were three-fold: (1) to assess the structure within individual modalities; (2) to compare structures between modalities; and (3) to assess the degree to which concepts organize categorically or randomly. Our results indicated significant and unique structure in all four modalities: perceptually, concepts organize based on prominent features such as shape, size, color, and parts; functionally, they group based on use and interaction; encyclopedically, they arrange based on commonality in location or behavior; and verbally, they group associatively or relationally. Visual/perceptual knowledge gives rise to the strongest hierarchical organization and is closest to classic taxonomic structure. Information is organized somewhat similarly in the perceptual and encyclopedic domains, which differs significantly from the structure in the functional and verbal domains. Notably, the verbal modality has the most unique organization, which is not at all categorical but also not random. The idiosyncrasy and complexity of conceptual structure across modalities raise the question of how all of these modality-specific experiences are fused together into coherent, multifaceted yet unified concepts. Accordingly, both methodological and theoretical implications of the present findings are discussed. PMID:23293593

Developing a Forest Health Index for public engagement and decision support using local climatic, ecological, and socioeconomic data

NASA Astrophysics Data System (ADS)

Arnott, J. C.; Katzenberger, J.; Cundiff, J.

2013-12-01

Forest health is an oft-used term without a generally accepted definition. Nonetheless, the concept of forest health continues to permeate scientific, resource management, and public discourse, and it is viewed as a helpful communication device for engagement on issues of concern to forests and their surrounding communities. Notwithstanding the challenges associated with defining the concept of 'forest health,' we present a model for assessing forest health at a watershed scale. Utilizing the Roaring Fork Valley, Colorado--a mountain watershed of 640,000 forested acres--as a case study, we have created a Forest Health Index that integrates a range of climatic, ecological, and socioeconomic data into an assessment organized along a series of public goals including, 1) Ecosystem Services, 2) Public Health & Safety, 3) Sustainable Use & Management, and 4) Ecological Integrity. Methods for this index were adopted from an earlier effort called the Ocean Health Index by Halpern et al, 2012. Indicators that represent drivers of change, such as temperature and precipitation, as well as effects of change, such as primary productivity and phenology, were selected. Each indicator is assessed by comparing a current status of that indicator to a reference scenario obtained through one of the following methods: a) statistical analysis of baseline data from the indicator record, b) commonly accepted normals, thresholds, limits, concentrations, etc., and c) subjective expert judgment. The result of this assessment is a presentation of graphical data and accompanying ratings that combine to form an index of health for the watershed forest ecosystem. We find this product to have potential merit for communities working to assess the range of conditions affecting forest health as well as making sense of the outcomes of those affects. Here, we present a description of the index methodology, data results from engagement with forest watershed stakeholders, example results of data analysis and indexing for the index, and a synthesis of lessons learned during this two-year development process.

[Assessing the benefits of digital health solutions in the societal reimbursement context].

2018-03-01

For a number of reasons, achieving reimbursability for digital health products has so far proven difficult. Demonstrating the benefits of the technology is the main hurdle in this context. The generally accepted evaluation processes, especially parallel group comparisons in randomized controlled trials (RCTs) for (clinical) benefit assessment, are primarily intended to deal with questions of (added) medical benefit. In contrast to drugs or classical medical devices, users of digital health solutions often profit from gaining autonomy, increased awareness and mindfulness, better transparency in the provision of care, and improved comfort, although there are also digital solutions with an interventional character targeting clinical outcomes (e. g. for indications such as anorexia, depression). Commonly accepted methods for evaluating (clinical) benefits primarily rely on medical outcomes, such as morbidity and mortality, but do not adequately consider additional benefits unique to digital health. The challenge is therefore to develop evaluation designs that respect the particularities of digital health without reducing the validity of the evaluations (especially with respect to safety). There is an increasing need for concepts that include both continuous feedback loops for adapting and improving an application while at the same time generate sufficient evidence for complex benefit assessments. This approach may help improve risk benefit ratio assessments of digital health when it comes to implementing digital innovations in healthcare.

Performance of distributed bagged stone dust barrier in combating coal-dust explosions

Plessis, J.J.L. du; Vassard, P.S.

1999-07-01

The Kloppersbos Research Facility of the CSIR's Division of Mining Technology has developed a new method of building stone dust barriers. The new barrier makes use of a previous concept of containing stone dust in a bag, but incorporates a new method of rupturing the bag. This was achieved by adapting the closing mechanism and by balancing the stone dust content with the void in the bag. The bagged barrier was extensively tested in the 200-m test gallery. During these tests, it became evident that these bags could be made to rupture and spread stone dust when subjected to smallermore » forces than those required for the most commonly used passive barrier, the Polish light barrier. To validate this, as well as to gain international acceptance of this new barrier, tests were conducted in the German experimental mine, DMT Tremonia, Dortmund. The barrier was evaluated against numerous methane-initiated coal-dust explosions. The paper describes the successful inhibition of coal-dust explosions at Kloppersbos and DMT tremonia. The barrier has been proven successfully for static pressures of 44 to 82 kpa, dynamic pressures of 12 to 36 kpa and for flame speeds as low as 23 m/s. This barrier is now accepted by the South African government and has been implemented in numerous South African collieries.« less

Recurrent pregnancy loss (RPL), commonly defined as 3 consecutive losses <10 weeks gestation, affects up to 5% of couples. Well-accepted causes include uterine malformation, antiphospholipid syndrome, and parental chromosomal abnormalities; however, the majority of RPL cases are idiopathic (up to 75%). This chapter covers these accepted causes of RPL and provides diagnosis and management strategies for patients falling within the above categories.

Acceptance and Avoidance Processes at Different Levels of Psychological Recovery from Enduring Mental Illness.

2015-01-01

Objective. This study examined the use of psychological acceptance and experiential avoidance, two key concepts of Acceptance and Commitment Therapy (ACT), in the psychological recovery process of people with enduring mental illness. Method. Sixty-seven participants were recruited from the metropolitan, regional, and rural areas of New South Wales, Australia. They all presented some form of chronic mental illness (at least 12 months) as reflected in DSM-IV Axis I diagnostic criteria. The Acceptance and Action Questionnaire (AAQ-19) was used to measure the presence of psychological acceptance and experiential avoidance; the Recovery Assessment Scale (RAS) was used to examine the levels of psychological recovery; and the Scales of Psychological Well-Being was used to observe if there are benefits in utilizing psychological acceptance and experiential avoidance in the recovery process. Results. An analysis of objectively quantifiable measures found no clear correlation between the use of psychological acceptance and recovery in mental illness as measured by the RAS. The data, however, showed a relationship between psychological acceptance and some components of recovery, thereby demonstrating its possible value in the recovery process. Conclusion. The major contribution of this research was the emerging correlation that was observed between psychological acceptance and positive levels of psychological well-being among individuals with mental illness.

Safer conception strategies can prevent HIV transmission between HIV-discordant partners while allowing them to conceive. However, HIV care providers in sub-Saharan Africa report they are not trained in safer conception, and patients are not routinely offered safer conception services. This mixed-methods pilot study evaluated the impact, acceptability, and feasibility of a novel Safer Conception Counseling Toolkit among providers and patients in Kenya. We enrolled 20 HIV-positive women, 10 HIV-discordant couples, and 10 providers from HIV care and treatment clinics. Providers completed questionnaires before/after training, and then counseled HIV-affected patients. Change in patient knowledge was assessed before/after counseling. Qualitative interviews were conducted among providers and patients. The Toolkit was associated with large, significant increases in patient knowledge, and provider confidence, knowledge, and favorable attitudes toward safer conception counseling; 20% felt confident before versus 100% after training (p < 0.01).

The Mk-18A Target Material Recovery Program (MTMRP) was established in 2015 to preserve the unique materials, e.g. 244Pu, in 65 previously irradiated Mk-18A targets for future use. This program utilizes existing capabilities at SRS and Savannah River National Laboratory (SRNL) to process targets, recover materials from them, and to package the recovered materials for shipping to ORNL. It also utilizes existing capabilities at ORNL to receive and store the recovered materials, and to provide any additional processing of the recovered materials or residuals required to prepare them for future beneficial use. The MTMRP is presently preparing for the processing ofmore » these valuable targets which is expected to begin in ~2019. As part of the preparations for operations, this report documents the preliminary acceptance criteria for the plutonium and heavy curium materials to be recovered from the Mk-18A targets at SRNL for transport and storage at ORNL. These acceptance criteria were developed based on preliminary concepts developed for processing, transporting, and storing the recovered Mk-18A materials. They will need to be refined as these concepts are developed in more detail.« less

This study adapted an existing computer-delivered brief alcohol intervention (cBAI) for use in Veterans with the hepatitis C virus (HCV) and examined its acceptability and feasibility in this patient population. A four-stage model consisting of initial pilot testing, qualitative interviews with key stakeholders, development of a beta version of the cBAI, and usability testing was used to achieve the study objectives. In-depth interviews gathered feedback for modifying the cBAI, including adding HCV-related content such as the health effects of alcohol on liver functioning, immune system functioning, and management of HCV, a preference for concepts to be displayed through "newer looking" graphics, and limiting the use of text to convey key concepts. Results from usability testing indicated that the modified cBAI was acceptable and feasible for use in this patient population. The development model used in this study is effective for gathering actionable feedback that can inform the development of a cBAI and can result in the development of an acceptable and feasible intervention for use in this population. Findings also have implications for developing computer-delivered interventions targeting behavior change more broadly.

Methodology Used to Assess Acceptability of Oral Pediatric Medicines: A Systematic Literature Search and Narrative Review.

PubMed

Mistry, Punam; Batchelor, Hannah

2017-06-01

Regulatory guidelines require that any new medicine designed for a pediatric population must be demonstrated as being acceptable to that population. There is currently no guidance on how to conduct or report on acceptability testing. Our objective was to undertake a review of the methods used to assess the acceptability of medicines within a pediatric population and use this review to propose the most appropriate methodology. We used a defined search strategy to identify literature reports of acceptability assessments of medicines conducted within pediatric populations and extracted information about the tools used in these studies for comparison across studies. In total, 61 articles were included in the analysis. Palatability was the most common (54/61) attribute measured when evaluating acceptability. Simple scale methods were most commonly used, with visual analog scales (VAS) and hedonic scales used both separately and in combination in 34 of the 61 studies. Hedonic scales alone were used in 14 studies and VAS alone in just five studies. Other tools included Likert scales; forced choice or preference; surveys or questionnaires; observations of facial expressions during administration, ease of swallowing, or ability to swallow the dosage; prevalence of complaints or refusal to take the medicine; and time taken for a nurse to administer the medicine. The best scale in terms of validity, reliability, feasibility, and preference to use when assessing acceptability remains unclear. Further work is required to select the most appropriate method to justify whether a medicine is acceptable to a pediatric population.

Establishment of an equivalence acceptance criterion for accelerated stability studies.

PubMed

Burdick, Richard K; Sidor, Leslie

2013-01-01

In this article, the use of statistical equivalence testing for providing evidence of process comparability in an accelerated stability study is advocated over the use of a test of differences. The objective of such a study is to demonstrate comparability by showing that the stability profiles under nonrecommended storage conditions of two processes are equivalent. Because it is difficult at accelerated conditions to find a direct link to product specifications, and hence product safety and efficacy, an equivalence acceptance criterion is proposed that is based on the statistical concept of effect size. As with all statistical tests of equivalence, it is important to collect input from appropriate subject-matter experts when defining the acceptance criterion.

Study of the intravaginal insert (IVI): acceptability, side effects, and post-coital spermicidal activity.

1984-01-01

The authors describe their experience with a group of 49 sexually active, already protected women in order to evaluate the acceptability, side effects and post-coital spermicidal activity of a new vaginal contraceptive. The intravaginal insert (IVI) consists of a polyester resin plug (sponge) containing a 5% solution of nonoxynol-9 bound in a cold formation process, and having a cotton loop attached to the lower end. The results of this study indicate that this new vaginal contraceptive is free of major side effects, is well accepted by users, and has strong spermicidal and mechanical activity. Future clinical testing in order to try its anti-conceptive effectiveness is warranted.

The objective of the present study was to analyze the knowledge and acceptance of the brain death (BD) concept among nursing students. The study was undertaken in the academic year of 2011 to 2012 in nursing students from the University of the South of Poland. The sample was carried out in compulsory sessions, in the 5 years of the nursing degree study, with a completion rate of 80%. The questionnaire was validated (PCID-DTO Ríos), self-administered, and completed anonymously. The completion rate was 93% (492 of 530). Of the students surveyed, 75% (n = 369) knew the concept of BD and considered it to mean a person's death. Of the rest, 19% (n = 93) did not know it, and the remaining 6% (n = 30) believed that it did not mean that a person was dead. The following variables were significantly related with the correct knowledge of the BD concept: 1) age (22 ± 2 years; P ≤ .001); 2) academic year (P ≤ .001); 3) discussion with friends about organ donation and transplantation (ODT) (P = .035); 4) partner's favorable attitude toward donation and transplantation (P = .009); and 5) being Catholic (P = .031). In the multivariate analysis, the following variables persisted as independent variables related to the BD concept: a) age [OR = 1.468 (1.247-1.697); P ≤ .001] and b) partner's opinion of ODT [OR = 2.248 (1.255-4.025); P = .006]. No association was found with attitude toward ODT. More than 25% of the students from the Jagiellonian University of Kraków did not know or accept the concept of brain death.

The concept of "work ability" is central for many sciences, especially for those related to working life and to rehabilitation. It is one of the important concepts in legislation regulating sickness insurance. How the concept is defined therefore has important normative implications. The concept is, however, often not sufficiently well defined. AIM AND METHOD The objective of this paper is to clarify, through conceptual analysis, what the concept can and should mean, and to propose a useful definition for scientific and practical work. RESULTS Several of the defining characteristics found in the literature are critically scrutinized and discussed, namely health, basic standard competence, occupational competence, occupational virtues, and motivation. These characteristics are related to the work tasks and the work environment. One conclusion is that we need two definitions of work ability, one for specific jobs that require special training or education, and one for jobs that most people can manage given a short period of practice. Having work ability, in the first sense, means having the occupational competence, the health required for the competence, and the occupational virtues that are required for managing the work tasks, assuming that the tasks are reasonable and that the work environment is acceptable. In the second sense, having work ability is having the health, the basic standard competence and the relevant occupational virtues required for managing some kind of job, assuming that the work tasks are reasonable and that the work environment is acceptable. CONCLUSION These definitions give us tools for understanding and discussing the complex, holistic and dynamic aspects of work ability, and they can lay the foundations for the creation of instruments for evaluating work ability, as well as help formulate strategies for rehabilitation.

Within sexual partnerships, men make many decisions about sexual behavior, reproductive goals, and HIV prevention. There are increasing calls to involve men in reproductive health and HIV prevention. This paper describes the process of creating and evaluating the acceptability of a safer conception intervention for men living with HIV who want to have children with partners at risk for acquiring HIV in KwaZulu-Natal, South Africa. Based on formative work conducted with men and women living with HIV, their partners, and providers, we developed an intervention based on principles of cognitive-behavioral therapy to support men in the adoption of HIV risk-reduction behaviors such as HIV-serostatus disclosure and uptake of and adherence to antiretroviral therapy. Structured group discussions were used to explore intervention acceptability and feasibility. Our work demonstrates that men are eager for reproductive health services, but face unique barriers to accessing them.

Mental Health: The Search for a Definition

PubMed Central

Tucker, D. K.; le Riche, W. Harding

1964-01-01

Various attempts to define the concept of “mental health” are examined. Value judgments permeate much mental health literature. Their use militates against obtaining an objective definition, capable of universal application. The acceptance of a definition including a value judgment implies taking an attitude toward a particular society and its social ideals. Present limits of competence only allow us to describe “mental health” conceptually. Such “untechnical” proposals are liable to be confused with “technical” (“scientific”) propositions. Multiple criteria are likely to be helpful in improving our concept of “mental health”. The intrusion of morals into the world of health is discussed as part of the contemporary intellectual dilemma of determined human behaviour versus human responsibility and the reality of moral values. It is suggested that “mental health” might consist simply of an individual's possession of insight into his own personality, combined with an honest recognition and acceptance of his condition.

Three experimental studies (N = 286) tested how priming the concepts of sex or romance influence the way people perceive other social media users. Participants first completed a word-search task containing sexual (intercourse, lust), romantic (love, heart), or control words. Participants then evaluated a target's sexual qualities and romantic qualities based on social media profiles, as well as rated their acceptance of the priming stimuli. Results suggested that sex primes led participants to judge targets as being more alluring, racy, and provocative, whereas romance primes led participants to judge targets as being more tender, sentimental, and kind. Both men and women found all primes to be equally acceptable content; women were not averse to these mainstream, non-explicit sexual stimuli. Findings are discussed in terms of viewing sex and romance as distinct, yet related networks of concepts and the need to disentangle sex, romance, and sexualized views of romance.

There is a plethora of concept inventories available for faculty to use, but it is not always clear exactly why you would use these tests, or how you should administer them and interpret the results. These research-based tests about physics and astronomy concepts are valuable because they allow for standardized comparisons among institutions, instructors, or over time. In order for these comparisons to be meaningful, you should use best practices for administering the tests. In interviews with 24 physics faculty, we have identified common questions that faculty members have about concept inventories. We have written this article to address common questions from these interviews and provide a summary of best practices for administering concept inventories.

Concept analysis: wrong-site surgery.

Watson, Donna S

2015-06-01

A concept analysis was conducted on the concept of wrong-site surgery (WSS) using the principle-based method by Penrod and Hupcey. It included analysis of WSS within the context of epistemological, pragmatic, linguistic, and logical principles. The analysis found that WSS is an important concept that is universally accepted, but the definition could be improved with inclusion of comprehensive labeling for types of WSS that may occur, such as wrong patient, wrong site, wrong level/part, wrong procedure, and wrong side. Wrong-site surgery falls into the domains of both nursing and medicine, and there is limited research on the topic specific to nursing interventions, perceptions, and contributions to prevent WSS.

2013-01-01

Background Two competing concepts address the development of involvement with psychoactive substances: the “gateway hypothesis” (GH) and common liability to addiction (CLA). Method The literature on theoretical foundations and empirical findings related to both concepts is reviewed. Results The data suggest that drug use initiation sequencing, the core GH element, is variable and opportunistic rather than uniform and developmentally deterministic. The association between risks for use of different substances, if any, can be more readily explained by common underpinnings than by specific staging. In contrast, the CLA concept is grounded in genetic theory and supported by data identifying common sources of variation in the risk for specific addictions. This commonality has identifiable neurobiological substrate and plausible evolutionary explanations. Conclusions Whereas the “gateway” hypothesis does not specify mechanistic connections between “stages”, and does not extend to the risks for addictions, the concept of common liability to addictions incorporates sequencing of drug use initiation as well as extends to related addictions and their severity, provides a parsimonious explanation of substance use and addiction co-occurrence, and establishes a theoretical and empirical foundation to research in etiology, quantitative risk and severity measurement, as well as targeted non-drug-specific prevention and early intervention.

The “Health Coaching” programme: a new patient-centred and visually supported approach for health behaviour change in primary care

PubMed Central

2013-01-01

Background Health related behaviour is an important determinant of chronic disease, with a high impact on public health. Motivating and assisting people to change their unfavourable health behaviour is thus a major challenge for health professionals. The objective of the study was to develop a structured programme of counselling in primary care practice, and to test its feasibility and acceptance among general practitioners (GPs) and their patients. Methods Our new concept integrates change of roles, shared responsibility, patient-centredness, and modern communication techniques—such as motivational interviewing. A new colour-coded visual communication tool is used for the purpose of leading through the 4-step counselling process. As doctors’ communication skills are crucial, communication training is a mandatory part of the programme. We tested the feasibility and acceptance of the “Health Coaching” programme with 20 GPs and 1045 patients, using questionnaires and semistructured interviewing techniques. The main outcomes were participation rates; the duration of counselling; patients’ self-rated behavioural change in their areas of choice; and ratings of motivational, conceptual, acceptance, and feasibility issues. Results In total, 37% (n=350) of the patients enrolled in step 1 completed the entire 4-Step counselling process, with each step taking 8–22 minutes. 50% of ratings (n=303) improved by one or two categories in the three-colour circle, and the proportion of favourable health behaviour ratings increased from 9% to 39%. The ratings for motivation, concept, acceptance, and feasibility of the “Health Coaching” programme were consistently high. Conclusions Our innovative, patient-centred counselling programme for health behaviour change was well accepted and feasible among patients and physicians in a primary care setting. Randomised controlled studies will have to establish cost-effectiveness and promote dissemination. PMID:23865509

A proof-of-concept (POC) aircraft is defined and the concept of interest described for each of the six aircraft developed by the Ames-Moffet Rotorcraft and Powered-Lift Flight Projects Division from 1970 through 1985; namely, the OV-10, the C-8A Augmentor Wing, the Quiet Short-Haul Research Aircraft (QSRA), the XV-15 Tilt Rotor Research Aircraft (TRRA), the Rotor Systems Research Aircraft (RSRA)-compound, and the yet-to-fly RSRA/X-Wing Aircraft. The program/project chronology and most noteworthy features of the concepts are reviewed. The paper discusses the significance of each concept and the project demonstrating it; it briefly looks at what concepts are on the horizon as potential POC research aircraft and emphasizes that no significant advanced concept in aviation technology has ever been accepted by civilian or military users without first completing a demonstration through flight testing.

Treatment acceptability among mexican american parents.

There is a void in the literature with regard to Hispanic parents' views about common interventions for children with behavior problems. The purpose of this study was to examine the treatment acceptability of child management techniques in a Mexican American sample. Parents' acculturation was also examined to determine if it would account for differences in treatment acceptability. Mexican American parents found response cost, a punishment-based technique, more acceptable than positive reinforcement-based techniques (e.g., differential attention). Results suggest that Mexican American parents' acculturation has little impact on acceptability of child management interventions. No association was found between mothers' acculturation and treatment acceptability. However, more acculturated Mexican American fathers viewed token economy as more acceptable than less acculturated fathers. Results are discussed in the context of clinical work and research with Mexican Americans.

Smart Home Technologies: Insights into Generation-Specific Acceptance Motives

NASA Astrophysics Data System (ADS)

Gaul, Sylvia; Ziefle, Martina

In this research we examine the generation specific acceptance motives of eHealth technologies in order to assess the likelihood of success for these new technologies. 280 participants (14 - 92 years of age) volunteered to participate in a survey, in which using motives and barriers toward smart home technologies were explored. The scenario envisaged was the use of a medical stent implemented into the body, which monitors automatically the health status and which is able to remotely communicate with the doctor. Participants were asked to evaluate the pros and cons of the usage of this technology, their acceptance motives and potential utilization barriers. In order to understand the complex nature of acceptance, personal variables (age, technical expertise, health status), individual's cognitive concepts toward ageing as well as perceived usefulness were related. Outcomes show that trust, believe in the reliability of technology, privacy and security as well as intimacy facets are essential for acceptance and should be considered in order to proactively design a successful rollout of smart home technologies.

A prospective study of acceptance of pain and patient functioning with chronic pain.

PubMed

McCracken, Lance M; Eccleston, Christopher

2005-11-01

Acceptance of chronic pain is emerging as an important concept in understanding ways that chronic pain sufferers can remain engaged with valued aspects of life. Recent studies have relied heavily on cross-sectional investigations at a single time point. The present study sought to prospectively investigate relations between acceptance of chronic pain and patient functioning. A sample of adults referred for interdisciplinary treatment of severe and disabling chronic pain was assessed twice, an average of 3.9 months apart. Results showed that pain and acceptance were largely unrelated. Pain at Time 2 was weakly related to measures of functioning at Time 2. On the other hand, acceptance at Time 1 was consistently related to patient functioning at Time 2. Those patients who reported greater acceptance at Time 1 reported better emotional, social, and physical functioning, less medication consumption, and better work status at Time 2. These data suggest that willingness to have pain, and to engage in activity regardless of pain, can lead to healthy functioning for patients with chronic pain. Treatment outcome and process studies may demonstrate the potential for acceptance-based clinical methods for chronic pain management.

The objective was to identify factors associated with decisions made by patients with amyotrophic lateral sclerosis (ALS) to accept or decline non-invasive ventilation (NIV) and/or gastrostomy in a prospective population-based study. Twenty-one people with ALS, recruited from the South-East ALS Register who made an intervention decision during the study timeframe underwent a face-to-face in-depth interview, with or without their informal caregiver present. Sixteen had accepted an intervention (11 accepted gastrostomy, four accepted NIV and one accepted both interventions). Five patients had declined gastrostomy. Thematic analysis revealed three main themes: (1) patient-centric factors (including perceptions of control, acceptance and need, and aspects of fear); (2) external factors (including roles played by healthcare professionals, family, and information provision); and (3) the concept of time (including living in the moment and the notion of 'right thing, right time'). Many aspects of these factors were inter-related. Decision-making processes for the patients were found to be complex and multifaceted and reinforce arguments for individualised (rather than 'algorithm-based') approaches to facilitating decision-making by people with ALS who require palliative interventions.

Muon Acceleration Concepts for NuMAX: "Dual-use" Linac and "Dogbone" RLA

DOE PAGES

Bogacz, S. A.

2018-02-01

In this paper, we summarize the current state of a concept for muon acceleration aimed at a future Neutrino Factory. The main thrust of these studies was to reduce the overall cost while maintaining performance by exploring the interplay between the complexity of the cooling systems and the acceptance of the accelerator complex. To ensure adequate survival for the short-lived muons, acceleration must occur at high average gradient. The need for large transverse and longitudinal acceptances drives the design of the acceleration system to an initially low RF frequency, e.g., 325 MHz, which is then increased to 650 MHz asmore » the transverse size shrinks with increasing energy. High-gradient normal conducting RF cavities at these frequencies require extremely high peak-power RF sources. Hence superconducting RF (SRF) cavities are chosen. Finally, we consider two cost effective schemes for accelerating muon beams for a stageable Neutrino Factory: exploration of the so-called "dual-use" linac concept, where the same linac structure is used for acceleration of both H - and muons and, alternatively, an SRF-efficient design based on a multi-pass (4.5) "dogbone" RLA, extendable to multi-pass FFAG-like arcs.« less

This paper presents the implementation status of the low-level radioactive waste (LLW) disposal program in Taiwan, including the disposal facility regulations, status of waste management, final disposal program, licensing procedures, waste acceptance criteria, site selection criteria and processes and preliminary disposal concepts. The first phase of site selection for low-level radioactive waste final disposal in Taiwan was implemented between 1992 and 2002. The site selection process adopted a Geographic Information System (GIS), Hierarchical Analysis System, Expert Evaluation System, and site reconnaissance. An incentive program for voluntary sites was also initiated. After a series of evaluations and discussion of 30 potentialmore » candidate sites, including 8 recommended sites, 5 qualified voluntary townships, and several remote uninhabited small islets, Hsiao-chiou islet was selected as the first priority candidate site in February 1998. The geological investigation work in Hsiao-chiou was conducted from March 1999 through October 2000. An Environmental Impact Statement Report (EIS) and the Investment Feasibility Study Report (IFS) were submitted to the Environmental Protection Agency (EPA) in November 2000 and to the Ministry of Economic Affairs (MOEA) in June 2001, respectively. Unfortunately, the site investigation was discontinued in 2002 due to political and public acceptance consideration. After years of planning, the second phase of the site selection process was launched in August 2004 and will be conducted through 2008. It is planned that a repository will be constructed in early 2009 and start to operate in 2014. The site selection process for the second phase is based on the earlier work and four potential candidate sites were selected for evaluation until 2005. A near surface disposal concept is proposed for a site located in the Taiwan strait, and cavern disposal concepts are proposed for three other sites located on the main island. This paper presents the implementation status of the LLW disposal program in Taiwan, including the disposal facility regulations, status of waste management, final disposal program, licensing procedures, waste acceptance criteria, site selection criteria and processes, and preliminary disposal concepts 'NIMBY' (Not in my backyard) is a critical problem for implementation of the final disposal project. Resistance from local communities has been continuously received during site characterization. To overcome this, an incentive program to encourage community acceptance has been approved by the Government. Programs for community promotion are being proposed and negotiations are also underway.

Prenatal alcohol exposure increases postnatal acceptability of nicotine odor and taste in adolescent rats.

PubMed

Mantella, Nicole M; Youngentob, Steven L

2014-01-01

Human studies indicate that alcohol exposure during gestation not only increases the chance for later alcohol abuse, but also nicotine dependence. The flavor attributes of both alcohol and nicotine can be important determinants of their initial acceptance and they both share the component chemosensory qualities of an aversive odor, bitter taste and oral irritation. There is a growing body of evidence demonstrating epigenetic chemosensory mechanisms through which fetal alcohol exposure increases adolescent alcohol acceptance, in part, by decreasing the aversion to alcohol's bitter and oral irritation qualities, as well as its odor. Given that alcohol and nicotine have noteworthy chemosensory qualities in common, we investigated whether fetal exposure to alcohol increased the acceptability of nicotine's odor and taste in adolescent rats. Study rats were alcohol-exposed during fetal development via the dams' liquid diet. Control animals received ad lib access to an iso-caloric, iso-nutritive diet throughout gestation. Odorant-induced innate behavioral responses to nicotine odor (Experiment 1) or orosensory-mediated responses to nicotine solutions (Experiment 2) were obtained, using whole-body plethysmography and brief access lick tests, respectively. Compared to controls, rats exposed to fetal alcohol showed an enhanced nicotine odor response that was paralleled by increased oral acceptability of nicotine. Given the common aversive component qualities imbued in the flavor profiles of both drugs, our findings demonstrate that like postnatal alcohol avidity, fetal alcohol exposure also influences nicotine acceptance, at a minimum, by decreasing the aversion of both its smell and taste. Moreover, they highlight potential chemosensory-based mechanism(s) by which fetal alcohol exposure increases the later initial risk for nicotine use, thereby contributing to the co-morbid expression with enhanced alcohol avidity. Where common chemosensory mechanisms are at play, our results suggest broader implications related to the consequence of fetal exposure with one substance of abuse and initial acceptability of others.

Rowe, Philip

2013-01-01

Residual limb shape capturing (Casting) consistency has a great influence on the quality of socket fit. Magnetic Resonance Imaging was used to establish a reliable reference grid for intercast and intracast shape and volume consistency of two common casting methods, Hands-off and Hands-on. Residual limbs were cast for twelve people with a unilateral below knee amputation and scanned twice for each casting concept. Subsequently, all four volume images of each amputee were semiautomatically segmented and registered to a common coordinate system using the tibia and then the shape and volume differences were calculated. The results show that both casting methods have intra cast volume consistency and there is no significant volume difference between the two methods. Inter- and intracast mean volume differences were not clinically significant based on the volume of one sock criteria. Neither the Hands-off nor the Hands-on method resulted in a consistent residual limb shape as the coefficient of variation of shape differences was high. The resultant shape of the residual limb in the Hands-off casting was variable but the differences were not clinically significant. For the Hands-on casting, shape differences were equal to the maximum acceptable limit for a poor socket fit. PMID:24348164

Simplified stereo-optical ultrasound plane calibration

Hoßbach, Martin; Noll, Matthias; Wesarg, Stefan

2013-03-01

Image guided therapy is a natural concept and commonly used in medicine. In anesthesia, a common task is the injection of an anesthetic close to a nerve under freehand ultrasound guidance. Several guidance systems exist using electromagnetic tracking of the ultrasound probe as well as the needle, providing the physician with a precise projection of the needle into the ultrasound image. This, however, requires additional expensive devices. We suggest using optical tracking with miniature cameras attached to a 2D ultrasound probe to achieve a higher acceptance among physicians. The purpose of this paper is to present an intuitive method to calibrate freehand ultrasound needle guidance systems employing a rigid stereo camera system. State of the art methods are based on a complex series of error prone coordinate system transformations which makes them susceptible to error accumulation. By reducing the amount of calibration steps to a single calibration procedure we provide a calibration method that is equivalent, yet not prone to error accumulation. It requires a linear calibration object and is validated on three datasets utilizing di erent calibration objects: a 6mm metal bar and a 1:25mm biopsy needle were used for experiments. Compared to existing calibration methods for freehand ultrasound needle guidance systems, we are able to achieve higher accuracy results while additionally reducing the overall calibration complexity.

Artificial gametes, the unnatural and the artefactual.

In debates on the ethics of artificial gametes, concepts of naturalness have been used in a number of different ways. Some have argued that the unnaturalness of artificial gametes means that it is unacceptable to use them in fertility treatments. Others have suggested that artificial gametes are no less natural than many other tissues or processes in common medical use. We suggest that establishing the naturalness or unnaturalness of artificial gametes is unlikely to provide easy answers as to the acceptability of using them in fertility medicine. However, we also suggest that we should be cautious about repudiating any relationship between nature and moral evaluation. The property of being natural or man-made may not per se tell us anything about an entity's moral status, but it has an important impact on the moral relationship between the creator and the created organism. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

How Places Shape Identity: The Origins of Distinctive LBQ Identities in Four Small U.S. Cities.

PubMed

Brown-Saracino, Japonica

2015-07-01

Tools from the study of neighborhood effects, place distinction, and regional identity are employed in an ethnography of four small cities with growing populations of lesbian, bisexual, and queer-identified (LBQ) women to explain why orientations to sexual identity are relatively constant within each site, despite informants' within-city demographic heterogeneity, but vary substantially across the sites, despite common place-based attributes. The author introduces the concept of "sexual identity cultures"--and reveals the defining role of cities in shaping their contours. She finds that LBQ numbers and acceptance, place narratives, and newcomers' encounters with local social attributes serve as touchstones. The article looks beyond major categorical differences (e.g., urban/rural) to understand how and why identities evolve and vary and to reveal the fundamental interplay of demographic, cultural, and other city features previously thought isolatable. The findings challenge notions of identity as fixed and emphasize the degree to which self-understanding and group understanding remain collective accomplishments.

Recovery from mental health challenges is beginning to be explored as an inherently social process. There is a need to measure social recovery. Targeted measures would be utilized in needs assessment, service delivery, and program evaluation. This paper reports on the first stage of development of a social recovery measure. Explore the social aspects of recovery as reported by individuals with lived experience. A qualitative study using thematic analysis of data from focus groups with 41 individuals in recovery. Three meta-themes of social recovery emerged: community, self-concept, and capacities. Each theme contained a number of sub-themes concerned with a sense of belonging, inherent acceptability of the self, and ability to cope with mental distress and engage socially. Study participants clearly spoke to common human needs to belong, contribute, and have hope for one's future. Findings converged with results of consumer-led research that emphasize the importance of overcoming the impact of illness on the self and social context.

Using RDF and Git to Realize a Collaborative Metadata Repository.

The German Center for Lung Research (DZL) is a research network with the aim of researching respiratory diseases. The participating study sites' register data differs in terms of software and coding system as well as data field coverage. To perform meaningful consortium-wide queries through one single interface, a uniform conceptual structure is required covering the DZL common data elements. No single existing terminology includes all our concepts. Potential candidates such as LOINC and SNOMED only cover specific subject areas or are not granular enough for our needs. To achieve a broadly accepted and complete ontology, we developed a platform for collaborative metadata management. The DZL data management group formulated detailed requirements regarding the metadata repository and the user interfaces for metadata editing. Our solution builds upon existing standard technologies allowing us to meet those requirements. Its key parts are RDF and the distributed version control system Git. We developed a software system to publish updated metadata automatically and immediately after performing validation tests for completeness and consistency.

Real Time Assessment of Potable Water Quality in Distribution Network based on Low Cost Multi-Sensor Array

Bhardwaj, Jyotirmoy; Gupta, Karunesh K.; Khatri, Punit

2018-03-01

New concepts and techniques are replacing traditional methods of water quality parameters measurement systems. This paper proposed a new way of potable water quality assessment in distribution network using Multi Sensor Array (MSA). Extensive research suggests that following parameters i.e. pH, Dissolved Oxygen (D.O.), Conductivity, Oxygen Reduction Potential (ORP), Temperature and Salinity are most suitable to detect overall quality of potable water. Commonly MSA is not an integrated sensor array on some substrate, but rather comprises a set of individual sensors measuring simultaneously different water parameters all together. Based on research, a MSA has been developed followed by signal conditioning unit and finally, an algorithm for easy user interfacing. A dedicated part of this paper also discusses the platform design and significant results. The Objective of this proposed research is to provide simple, efficient, cost effective and socially acceptable means to detect and analyse water bodies regularly and automatically.

Personalized Guideline-Based Treatment Recommendations Using Natural Language Processing Techniques.

Clinical guidelines and clinical pathways are accepted and proven instruments for quality assurance and process optimization. Today, electronic representation of clinical guidelines exists as unstructured text, but is not well-integrated with patient-specific information from electronic health records. Consequently, generic content of the clinical guidelines is accessible, but it is not possible to visualize the position of the patient on the clinical pathway, decision support cannot be provided by personalized guidelines for the next treatment step. The Systematized Nomenclature of Medicine - Clinical Terms (SNOMED CT) provides common reference terminology as well as the semantic link for combining the pathways and the patient-specific information. This paper proposes a model-based approach to support the development of guideline-compliant pathways combined with patient-specific structured and unstructured information using SNOMED CT. To identify SNOMED CT concepts, a software was developed to extract SNOMED CT codes out of structured and unstructured German data to map these with clinical pathways annotated in accordance with the systematized nomenclature.

The Early History of Bioenergy

NASA Astrophysics Data System (ADS)

Radu, Popa

Energy is most commonly defined as the potential to do work. The maintenance of the living state requires a constant flow of energy through the system. The concept of energy is not easily implemented in computational models of life and is therefore often ignored in artificial life models. Some models even regard as irrelevant the energetic problematic (dissipation, irreversibility, couplings, energy currencies), in the physical realization of a biological system" (Ruiz-Mirazo et al. 1998). Examples of such models are Rosen's (M,R)-system, Varela's autopoietic models, Kauffman's autocatalytic set, and Fontana's algorithmic chemistry (see Appendix A). However, many origin-of-life theories maintain the primordial importance of energy for early life. Although everyone accepts that energetic constraints are important when describing material-based living systems, a problem arises when we have to consider whether or not they affect the very logic of the organization (Morán et al. 1999). It is argued here that energy considerations are not only primordial, but intimately related to the essence of life as well.

Care systematization in psychiatric nursing within the psychiatric reform context.

PubMed

Hirdes, A; Kantorski, L P

2002-02-01

The aim of this study was to approach care systematization in psychiatric nursing in two psychiatric disorder patients who attended 'Nossa Casa', São Lourenço do Sul, RS, Brazil. Nossa Casa services psychiatric patients in the community, focussing on: (i) permanence in their environment, allowing patients to remain close to their families and social spheres; (ii) integral attendance to meet individual needs; (iii) respecting individual differences; (iv) rehabilitation practices; and (v) social reinsertion. Concepts and assumptions of the psychiatric reform and the Irving's nursing process were used as theoretical-methodological references to elaborate this systematization. A therapeutic project for the psychiatric patient was elaborated, in accordance with the interdisciplinary proposal accepted by Nossa Casa. Interdisciplinary team intervention, guided by a previously discussed common orientation and defined through an individualized therapeutic project, allowed for an effective process of psychosocial rehabilitation. The authors concluded that a therapeutic project based on the mentioned premises leads to consistent, comprehensive, dialectical and ethical assistance in mental health, thereby reinstating the citizenship of psychiatric patients.

Interrelating Behavioral Measures of Distress Tolerance with Self-Reported Experiential Avoidance.

Experiential avoidance and distress intolerance play a central role in novel behavior therapies, yet they appear to overlap considerably the REBT concept of low frustration tolerance. Using baseline data from 100 adult cigarette smokers enrolled in a clinical trial of smoking cessation therapies, the present study evaluated the convergent validity of common questionnaire measures of experiential avoidance (Acceptance and Action Questionnaire; AAQ; Hayes et al. 2004, and Avoidance and Inflexibility Scale: AIS; Gifford et al. 2004) and behavioral measures of distress tolerance (computerized Mirror Tracing Persistence Task: MTPT-C: Strong et al. 2003; computerized Paced Auditory Serial Addition Task; PASAT-C; Lejuez et al. 2003). The distress tolerance measures correlated significantly (r = .29) with one another. However, the questionnaire measures of experiential avoidance did not correlate with each other, nor with the behavioral measures. Further research is needed on the validity of measuring experiential avoidance by self-report and of the overlap versus distinctiveness of seemingly similar constructs such as experiential avoidance, distress tolerance, and frustration tolerance.

Fibromyalgia: harmonizing science with clinical practice considerations.

PubMed

Perrot, Serge; Dickenson, Anthony H; Bennett, Robert M

2008-01-01

This review summarizes the present and emerging knowledge base on the pathophysiology, diagnosis, and management of fibromyalgia. Fibromyalgia is the most common chronic pain syndrome encountered in general medicine and rheumatology. Historically, contemporary concepts of fibromyalgia have evolved in terms of its clinical description and parallel advances in the understanding of its pathophysiology. A generally accepted paradigm postulates that fibromyalgia is the clinical expression of a rheumatologic disorder in which the associated pain is driven primarily by central sensitization and possibly through changes in several neuronal systems but not necessarily reliant on peripheral processes. Several agents, including serotonin-norepinephrine reuptake inhibitors (ie, duloxetine and milnacipran), opioids (ie, tramadol), and the alpha2-delta ligand pregabalin, which recently received U.S. regulatory approval for the treatment of fibromyalgia, have been evaluated in clinical trials, demonstrating benefit in terms of pain reduction and improvement in core symptoms (ie, fatigue and sleep disturbance). The European League Against Rheumatism has developed updated guidelines for the management of fibromyalgia.

Oral mucositis is one of the common side effects of chemotherapy treatment with potentially severe implications. Despite several treatment approaches by conventional and complementary western medicine, the therapeutic outcome is often not satisfactory. Traditional Chinese Medicine (TCM) offers empirical herbal formulas for the treatment of oral ulceration which are used in adaptation to chemotherapy-induced mucositis. While standard concepts for TCM treatment do not exist and acceptance by conventional oncologists is still low, we conducted a review to examine the evidence of Chinese herbal treatment in oral mucositis. Eighteen relevant studies on 4 single herbs, 2 combinations of 2 herbs, and 11 multiherbal prescriptions involving 3 or more compounds were included. Corresponding molecular mechanisms were investigated. The knowledge about detailed herbal mechanisms, especially in multi-herbal prescriptions is still limited. The quality of clinical trials needs further improvement. Meta-analysis on the existent database is not possible but molecular findings on Chinese medicinal herbs indicate that further research is still promising for the treatment of chemotherapy-induced oral mucositis.

Sarah A. Roache and Lawrence O. Gostin's recent editorial comprehensively presents soda taxation rationales from a public health perspective. While we essentially agree that soda taxes are gaining momentum, this commentary expands upon the need for a better understanding of the policy processes underlying their development and implementation. Indeed, the umbrella concept of soda taxation actually covers a diversity of objectives and mechanisms, which may not only condition the feasibility and acceptability of a proposal, but also alter its impact. We briefly highlight some conditions that may have influenced soda tax policy processes and why further theory-driven case studies may be instructive. © 2018 The Author(s); Published by Kerman University of Medical Sciences.

As a consequence of the growing interest in, and development of, various types of food with nutritional benefits, the modern consumer views their kitchen cabinet more and more as a medicine cabinet. Given that consumer evaluation of food is considered key to the successful production, marketing and finally consumption of food, a procedure commonly used in medical fields was employed to systematically review and summarize evidence of consumer evaluation studies on nutritious foods. The focus is primarily on consumer understanding of nutritious food and the underlying determinants of consumer evaluation. Our results highlight four groups of key determinants: (1) nutrition knowledge and information; (2) attitudes, beliefs, perceptions and behavioural determinants; (3) price, process and product characteristics; and (4) socio-demographics. The findings also point to the importance of understanding consumer acceptance as one many concepts in the consumer evaluation process, and provide support for developing appropriate strategies for improving health and well-being of consumers.

Necroptosis is programmed necrosis, a process which has been studied for over a decade. The most common accepted mechanism is through the RIP1-RIP3-MLKL axis to regulate necroptotic cell death. As a result of previous studies on necroptosis, positive regulation for promoting necroptosis such as HSP90 stabilization and hyperactivation of TAK1 on RIP1 is clear. Similarly, the negative regulation of necroptosis, such as through caspase 8, c-FLIP, CHIP, MK2, PELI1, ABIN-1, is also clear. Therefore, the promise of corresponding applications in treating diseases becomes hopeful. Studies have shown that necroptosis is involved in the development of many diseases, such as ischemic injury diseases in various organs, neurodegenerative diseases, infectious diseases, and cancer. Given these results, drugs that inhibit or trigger necroptosis can be discovered to treat diseases. In this review, we briefly introduce up to date concepts concerning the mechanism of necroptosis, the diseases that involve necroptosis, and the drugs that can be applied to treat such diseases.

There is no commonly accepted standardized terminology for oral diagnoses. The purpose of this article is to report the development of a standardized dental diagnostic terminology by a work group of dental faculty members. The work group developed guiding principles for decision making and adhered to principles of terminology development. The members used an iterative process to develop a terminology incorporating concepts represented in the Toronto/University of California, San Francisco/Creighton University and International Classification of Diseases (ICD)-9/10 codes and periodontal and endodontic diagnoses. Domain experts were consulted to develop a final list of diagnostic terms. A structure was developed, consisting of thirteen categories, seventy-eight subcategories, and 1,158 diagnostic terms, hierarchically organized and mappable to other terminologies and ontologies. Use of this standardized diagnostic terminology will reinforce the diagnosis-treatment link and will facilitate clinical research, quality assurance, and patient communication. Future work will focus on implementation and approaches to enhance the validity and reliability of diagnostic term utilization. PMID:21205730

Inference and representations of hand actions through grasping synergies. Comment on "Grasping synergies: A motor-control approach to the mirror neuron mechanism" by D'Ausilio, Bartoli, and Maffongelli

Santello, Marco

2015-03-01

The concept of synergy, denoting the coordination of multiple elements working together toward a common goal, has been extensively studied to understand how the central nervous system (CNS) controls movement (for review see [5,9]). Although this definition is appealing in its simplicity, 'multiple elements', 'working together', and 'common goal' each take different meanings depending on the scale at which a given sensorimotor system is studied, whether the 'working together' is defined in spatial and/or temporal domains, and the hypothesized synergy's 'common goal'. For example, the elements involved in a synergy can be defined as single motor units, muscles, or joints. Similarly, the goal of a synergy may be defined as a means available to the CNS to 'simplify' the control of multiple elements, or to minimize a given cost function or movement feature - all of which may differ across tasks and tasks conditions. These considerations underscore the fact that a universally accepted definition of synergies and their functional role remains to be established (for review see [6]). Thus, the nature and functional role(s) of synergies is still debated in the literature. Nevertheless, it is generally agreed that the reduction in the number of independent degrees of freedom that is manifested through synergies emerges from the interaction of biomechanical and neural factors constraining the spatial and temporal coordination of multiple muscles.

Color associations among designers and non-designers for common warning and operation concepts.

This study examined color-concept associations among designers and non-designers with commonly used warning and operation concepts. This study required 199 designers and 175 non-designers to indicate their choice among nine colors to associate with each of the 38 concepts in a color-concept table. The results showed that the designers and non-designers had the same color associations and similar strengths of stereotypes for 17 concepts. The strongest color-concept stereotypes for both groups were red-danger, red-fire, and red-hot. However, the designers and non-designers had different color associations for the concepts of escape (green, red), increase (green, red), potential hazard (red, orange), fatal (black, red), and normal (white, green), while the strengths of the 16 remaining associations for both groups were not at equivalent levels. These findings provide ergonomists and design practitioners with a better understanding of population stereotypes for color coding, and consequently to effectively use colors in their user-centered designs.

Since 2003 when the international norm for implementation of quality management in medical laboratories (EN ISO 15189, Medical laboratories--Particular requirements for quality and competence) was established and accepted, accreditation has become practical, generally accepted method of quality management and confirmation of technical competence of medical laboratories in the whole world. This norm has been translated into Croatian and accepted by the Croatian Institute for Norms as Croatian norm. Accreditation is carried out on voluntary basis by the Croatian Accreditation Agency that has up to now accredited two clinical medical biochemical laboratories in the Republic of Croatia. Advantages of accredited laboratory lie in its documented management system, constant improvement and training, reliability of test results, establishing users' trust in laboratory services, test results comparability and interlaboratory (international) test results acceptance by adopting the concept of metrological traceability in laboratory medicine.

From Interaction to Co-Association —A Fisher r-To-z Transformation-Based Simple Statistic for Real World Genome-Wide Association Study

Currently, the genetic variants identified by genome wide association study (GWAS) generally only account for a small proportion of the total heritability for complex disease. One crucial reason is the underutilization of gene-gene joint effects commonly encountered in GWAS, which includes their main effects and co-association. However, gene-gene co-association is often customarily put into the framework of gene-gene interaction vaguely. From the causal graph perspective, we elucidate in detail the concept and rationality of gene-gene co-association as well as its relationship with traditional gene-gene interaction, and propose two Fisher r-to-z transformation-based simple statistics to detect it. Three series of simulations further highlight that gene-gene co-association refers to the extent to which the joint effects of two genes differs from the main effects, not only due to the traditional interaction under the nearly independent condition but the correlation between two genes. The proposed statistics are more powerful than logistic regression under various situations, cannot be affected by linkage disequilibrium and can have acceptable false positive rate as long as strictly following the reasonable GWAS data analysis roadmap. Furthermore, an application to gene pathway analysis associated with leprosy confirms in practice that our proposed gene-gene co-association concepts as well as the correspondingly proposed statistics are strongly in line with reality.

Unravelling the concept of consumer preference: implications for health policy and optimal planning in primary care.

PubMed

Foster, Michele M; Earl, Peter E; Haines, Terry P; Mitchell, Geoffrey K

2010-10-01

Accounting for consumer preference in health policy and delivery system design makes good economic sense since this is linked to outcomes, quality of care and cost control. Probability trade-off methods are commonly used in policy evaluation, marketing and economics. Increasingly applied to health matters, the trade-off preference model has indicated that consumers of health care discriminate between different attributes of care. However, the complexities of the health decision-making environment raise questions about the inherent assumptions concerning choice and decision-making behavior which frame this view of consumer preference. In this article, we use the example of primary care in Australia as a vehicle to examine the concept of 'consumer preference' from different perspectives within economics and discuss the significance of how we model preferences for health policy makers. In doing so, we question whether mainstream thinking, namely that consumers are capable of deliberating between rival strategies and are willing to make trade-offs, is a reliable way of thinking about preferences given the complexities of the health decision-making environment. Alternative perspectives on preference can assist health policy makers and health providers by generating more precise information about the important attributes of care that are likely to enhance consumer engagement and optimise acceptability of health care.

An updated concept of coagulation with clinical implications.

PubMed

Romney, Gregory; Glick, Michael

2009-05-01

Over the past century, a series of models have been put forth to explain the coagulation mechanism. The coagulation cascade/waterfall model has gained the most widespread acceptance. This model, however, has problems when it is used in different clinical scenarios. A more recently proposed cell-based model better describes the coagulation process in vivo and provides oral health care professionals (OHCPs) with a better understanding of the clinical implications of providing dental care to patients with potentially increased bleeding tendencies. The authors conducted a literature search using the PubMed database. They searched for key words including "coagulation," "hemostasis," "bleeding," "coagulation factors," "models," "prothrombin time," "activated partial thromboplastin time," "international normalized ratio," "anticoagulation therapy" and "hemophilia" separately and in combination. The coagulation cascade/waterfall model is insufficient to explain coagulation in vivo, predict a patient's bleeding tendency, or correlate clinical outcomes with specific laboratory screening tests such as prothrombin time, activated partial thromboplastin time and international normalized ratio. However, the cell-based model of coagulation that reflects the in vivo process of coagulation provides insight into the clinical ramifications of treating dental patients with specific coagulation factor deficiencies. Understanding the in vivo coagulation process will help OHCPs better predict a patient's bleeding tendency. In addition, applying the theoretical concept of the cell-based model of coagulation to commonly used laboratory screening tests for coagulation and bleeding will result in safer and more appropriate dental care.

Microvascular surgery following tumor resection has become an important field of oral maxillofacial surgery (OMFS). Following the surveys on current reconstructive practice in German-speaking countries and Europe, this paper presents the third phase of the project when the survey was conducted globally. The DOESAK questionnaire has been developed via a multicenter approach with maxillofacial surgeons from 19 different hospitals in Germany, Austria and Switzerland. It was distributed in three different phases to a growing number of maxillofacial units in German-speaking clinics, over Europe and then worldwide. Thirty-eight units from Germany, Austria and Switzerland, 65 remaining European OMFS-departments and 226 units worldwide responded to the survey. There is wide agreement on the most commonly used flaps, intraoperative rapid sections and a trend towards primary bony reconstruction. No uniform concepts can be identified concerning osteosynthesis of bone transplants, microsurgical techniques, administration of supportive medication and postoperative monitoring protocols. Microsurgical reconstruction is the gold standard for the majority of oncologic cases in Europe, but worldwide, only every second unit has access to this technique. The DOESAK questionnaire has proven to be a valid and well accepted tool for gathering information about current practice in reconstructive OMFS surgery. The questionnaire has been able to demonstrate similarities, differences and global inequalities. Copyright © 2015 European Association for Cranio-Maxillo-Facial Surgery. Published by Elsevier Ltd.

Factors impacting on nurses' transference of theoretical knowledge of holistic care into clinical practice.

PubMed

Henderson, Saras

2002-12-01

Since nurse education moved to universities, a reoccurring concern of health consumers, health administrators, and some practising nurses is that nurses are not able to transfer the theoretical knowledge of holistic care into practice. Much has been written about this concern usually under the heading of the theory-practice gap. A common reason that has been highlighted as the cause of this gap is that the theoretical knowledge that nurses learn in academia is predicated on concepts such as humanism and holistic caring. In contrast, the bureaucratic organisation where nurses provide care tends to be based on management concepts where cost containment and outcome measures are more acceptable. Hence nurses' learned values of holistic caring are pitted against the reality of the practice setting. So what is this practice reality? This paper attempts to provide an insider view of why the theoretical knowledge of holistic care may be difficult to enact in the clinical setting. In-depth taped interviews with nurses and participant observation were conducted in acute care hospitals in Western Australia. The interviews were transcribed verbatim and analysed using the constant comparative method. The findings indicated that utilitarian nursing and role models had impacted on the transference of theoretical knowledge of holistic care into practice. The paper outlines some measures that nurses themselves can undertake to ensure the narrowing of the theory-practice gap in this area.

Synopsis Current clinical concepts are reviewed regarding the epidemiology, anatomy, evaluation and treatment of pediatric ankle fractures. Correct diagnosis and management relies on appropriate exam, imaging, and knowledge of fracture patterns specific to children. Treatment is guided by patient history, physical examination, plain film radiographs and, in some instances, CT. Treatment goals are to restore acceptable limb alignment, physeal anatomy, and joint congruency. For high risk physeal fractures, patients should be monitored for growth disturbance as needed until skeletal maturity. PMID:26589088

1981-01-01

An electronic flight-guidance display format was designed for use in evaluations of the collimated head-up display concept applied to transport aircraft landing. In the design process of iterative evaluation and modification, some general principles, or guidelines, applicable to electronic flight displays were suggested. The usefulness of an indication of instantaneous inertial flightpath was clearly demonstrated. Evaluator pilot acceptance of the unfamiliar display concepts was very positive when careful attention was given to indoctrination and training.

[The function of a general concept of disease from an historical perspective].

PubMed

Hess, V; Herrn, R

2015-01-01

This article questions why medicine fails to provide a general concept of disease for use by doctors, patients and society because the lack of such a unified concept inhibits any definitive distinction between "deviant" and "disease". By providing an historical overview of the particularities related to this question the authors demonstrate that the ever-changing concepts of disease were not driven by the process through which medicine became a science. In contrast to naturalistic concepts of disease, anthropological, sociocultural and psychosomatic concepts are grounded in an understanding of disease that cannot be determined, described and categorized by pathology alone. As a consequence, disease can only be determined or defined in relation to social and scientific frames of reference, as illustrated by an example from the Berlin Nervenklinik (psychiatric clinic) in the early twentieth century. The ways in which the definition of a disease concept represents a normative interpretation can be observed. The authors of this paper argue for the acceptance of this normative definition as a matter of societal agreement. Consequently, transparency is required in the shaping of general disease concepts.

When intensions do not map onto extensions: Individual differences in conceptualization.

PubMed

Hampton, James A; Passanisi, Alessia

2016-04-01

Concepts are represented in the mind through knowledge of their extensions (the class of items to which the concept applies) and intensions (features that distinguish that class of items). A common assumption among theories of concepts is that the 2 aspects are intimately related. Hence if there is systematic individual variation in concept representation, the variation should correlate between extensional and intensional measures. A pair of individuals with similar extensional beliefs about a given concept should also share similar intensional beliefs. To test this notion, exemplars (extensions) and features (intensions) of common categories were rated for typicality and importance respectively across 2 occasions. Within-subject consistency was greater than between-subjects consensus on each task, providing evidence for systematic individual variation. Furthermore, the similarity structure between individuals for each task was stable across occasions. However, across 5 samples, similarity between individuals for extensional judgments did not map onto similarity between individuals for intensional judgments. The results challenge the assumption common to many theories of conceptual representation that intensions determine extensions and support a hybrid view of concepts where there is a disconnection between the conceptual resources that are used for the 2 tasks.

Prevention concept in industry: improvement in occupational safety and health protection--an empirical study.

PubMed

Ramsauer, F

2001-12-01

This prevention concept offers a contribution to the expansion of the set of instruments for occupational safety and health protection within workplace prevention. The concept involves the multilateral analysis of work conditions. The utilized instruments include a strategy group, a survey, a health issue round table, and an analysis of work demands, and lead to synergy effects at the results level. Employees are drawn into the analysis of work conditions and workplace design solutions for the improvement of the work situation. The prevention concept was tested in a large company and its application established in practice. It was accepted by all participants, and the comparison with the previous situation (defined only through the analysis of work demands) demonstrated a significant improvement in health protection.

Developmental Change and Time-Specific Variation in Global and Specific Aspects of Self-Concept in Adolescence and Association with Depressive Symptoms

PubMed Central

Kuzucu, Yasar; Bontempo, Daniel E.; Hofer, Scott M.; Stallings, Michael C.; Piccinin, Andrea M.

2014-01-01

Previous research has demonstrated that adolescents make differential self-evaluations in multiple domains that include physical appearance, academic competence, and peer acceptance. We report growth curve analyses over a seven year period from age 9 to age 16 on the six domains of the Harter Self-Perception Profile for Children. In general, we find little change in self-concept, on average, but do find substantial individual differences in level, rate of change, and time-specific variation in these self- evaluations. The results suggest that sex differences and adoptive status were related to only certain aspects of the participants’ self-concept. Depressive symptoms were found to have significant effects on individual differences in rate of change and on time-specific variation in general self-concept, as well as on some of the specific domains of self-concept.

[Causal inference in medicine--a historical view in epidemiology].

Tsuda, T; Babazono, A; Mino, Y; Matsuoka, H; Yamamoto, E

1996-07-01

Changes of causal inference concepts in medicine, especially those having to do with chronic diseases, were reviewed. The review is divided into five sections. First, several articles on the increased academic acceptance of observational research are cited. Second, the definitions of confounder and effect modifier concepts are explained. Third, the debate over the so-called "criteria for causal inference" was discussed. Many articles have pointed out various problems related to the lack of logical bases for standard criteria, however, such criteria continue to be misapplied in Japan. Fourth, the Popperian and verificationist concepts of causal inference are summarized. Lastly, a recent controversy on meta-analysis is explained. Causal inference plays an important role in epidemiologic theory and medicine. However, because this concept has not been well-introduced in Japan, there has been much misuse of the concept, especially when used for conventional criteria.

Processes Linking Weight Status and Self-Concept Among Girls From Ages 5 to 7 Years

PubMed Central

Davison, Kirsten Krahnstoever; Birch, Leann Lipps

2008-01-01

This study assessed the relationship between girls’ weight status and self-concept and examined peer teasing and parent criticism as potential mediators of this relationship. Data were collected for 182 girls and their parents when the girls were 5 and 7 years old. At each age, girls’ body mass index, self-concept, peer weight-related teasing (child report), and parents’ criticism of girls’ weight status (spouse report) were assessed. At ages 5 and 7, girls who were more overweight reported lower self-concept. Peer teasing and parent criticism mediated the relationship between weight status and self-concept at age 7, but not at age 5. In addition, the duration and timing of parent criticism across ages 5 and 7 mediated the association between girls’ weight status at age 5 and perceived peer acceptance at age 7. PMID:12220051

Numerical modeling analysis of stress transfer modification concepts for deep longwall mines. Report of investigations/1995

Vandergrift, T.L.; Jude, C.V.

1995-12-31

This U.S. Bureau of Mines (USBM) report evaluates three stress-transfer-modification concepts for their potential in reducing longwall gate road stresses and closures. In each of the three concepts--packwalling, gob infilling, and entry filling--support structures are constructed on the headgate side of the panel parallel with or inby the face line. When the headgate becomes the tailgate of the adjacent panel, these structures are in place to accept stresses transferred from the mined-out panel. Using the USBM nonlinear boundary-element program MULSIM/NL, baseline models of typical longwall stress transfer behavior were developed for both intermediate depth and deep mining conditions. These modelsmore » were verified by comparing model results with field measurements and observations. The stress-transfer-modification concepts were then incorporated into the deep baseline model to quantify the effects of each concept on tailgate closure.« less

Identifying With a Stereotype: The Divergent Effects of Exposure to Homosexual Television Characters.

PubMed

McLaughlin, Bryan; Rodriguez, Nathian S

2017-01-01

Scholars examining homosexual television characters have typically come to one of two conclusions: either exposure to homosexual characters can lead to increased acceptance, or homosexual characters serve to reaffirm negative stereotypes. We seek to bridge these two bodies of research by introducing the concept of stereotyped identification-the idea that cognitively and emotionally identifying with fictional characters can increase acceptance of minorities, while reinforcing implicit stereotypes about how they look, act, and talk. Results from our national survey (N = 972) offer support for this hypothesis.

Minimal acceptable care as a vital component to Missouri's trauma system.

Helling, Thomas S

2002-07-01

Immediate attention to life-threatening injuries and expeditious transfer of major and complex wounds to tertiary care trauma centers are the cornerstones of any trauma system. Rapid assessment and "minimalization" of care should be the buzz-word of rural (Level III) and suburban (Level II) trauma centers in order to provide quickest treatment of injuries by timely referral of patients for definitive attention. This concept is called minimal acceptable care and may serve to improve patient outcome by reducing the interval to ultimate treatment and avoidance of duplication of services.

Adaptive evolutionary conservation: towards a unified concept for defining conservation units.

PubMed

Fraser, D J; Bernatchez, L

2001-12-01

Recent years have seen a debate over various methods that could objectively prioritize conservation value below the species level. Most prominent among these has been the evolutionarily significant unit (ESU). We reviewed ESU concepts with the aim of proposing a more unified concept that would reconcile opposing views. Like species concepts, conflicting ESU concepts are all essentially aiming to define the same thing: segments of species whose divergence can be measured or evaluated by putting differential emphasis on the role of evolutionary forces at varied temporal scales. Thus, differences between ESU concepts lie more in the criteria used to define the ESUs themselves rather than in their fundamental essence. We provide a context-based framework for delineating ESUs which circumvents much of this situation. Rather than embroil in a befuddled debate over an optimal criterion, the key to a solution is accepting that differing criteria will work more dynamically than others and can be used alone or in combination depending on the situation. These assertions constitute the impetus behind adaptive evolutionary conservation.

The 'wise list'- a comprehensive concept to select, communicate and achieve adherence to recommendations of essential drugs in ambulatory care in Stockholm.

2011-04-01

The aim was to present and evaluate the impact of a comprehensive strategy over 10 years to select, communicate and achieve adherence to essential drug recommendations (EDR) in ambulatory care in a metropolitan healthcare region. EDRs were issued and launched as a 'Wise List' by the regional Drug and Therapeutics Committee in Stockholm. This study presents the concept by: (i) documenting the process for selecting, communicating and monitoring the impact of the 'Wise List'; (ii) analysing the variation in the number of drug substances recommended between 2000 and 2010; (iii) assessing the attitudes to the 'Wise List' among prescribers and the public; (iv) evaluating the adherence to recommendations between 2003 and 2009. The 'Wise List' consistently contained 200 drug substances for treating common diseases. The drugs were selected based on their efficacy, safety, suitability and cost-effectiveness. The 'Wise List' was known among one-third of a surveyed sample of the public in 2002 after initial marketing campaigns. All surveyed prescribers knew about the concept and 81% found the recommendations trustworthy in 2005. Adherence to recommendations increased from 69% in 1999 to 77% in 2009. In primary care, adherence increased from 83% to 87% from 2003 to 2009. The coefficient of variation (CV%) decreased from 6.1% to 3.8% for 156 healthcare centres between these years. The acceptance of the 'Wise List' in terms of trust among physicians and among the public and increased adherence may be explained by clear criteria for drug recommendations, a comprehensive communication strategy, electronic access to recommendations, continuous medical education and involvement of professional networks and patients.

Insecticide treated curtains and residual insecticide treatment to control Aedes aegypti: An acceptability study in Santiago de Cuba.

PubMed

Pérez, Dennis; Van der Stuyft, Patrick; Toledo, María Eugenia; Ceballos, Enrique; Fabré, Francisco; Lefèvre, Pierre

2018-01-01

Within the context of a field trial conducted by the Cuban vector control program (AaCP), we assessed acceptability of insecticide-treated curtains (ITCs) and residual insecticide treatment (RIT) with deltamethrin by the community. We also assessed the potential influence of interviewees' risk perceptions for getting dengue and disease severity. We embedded a qualitative study using in-depth interviews in a cluster randomized trial (CRT) testing the effectiveness of ITCs and RIT in Santiago de Cuba. In-depth interviews (N = 38) were conducted four and twelve months after deployment of the tools with people who accepted the tools, who stopped using them and who did not accept the tools. Data analysis was deductive. Main reasons for accepting ITCs at the start of the trial were perceived efficacy and not being harmful to health. Constraints linked to manufacturer instructions were the main reason for not using ITCs. People stopped using the ITCs due to perceived allergy, toxicity and low efficacy. Few heads of households refused RIT despite the noting reasons for rejection, such as allergy, health hazard and toxicity. Positive opinions of the vector control program influenced acceptability of both tools. However, frequent insecticide fogging as part of routine AaCP vector control actions diminished perceived efficacy of both tools and, therefore, acceptability. Fifty percent of interviewees did feel at risk for getting dengue and considered dengue a severe disease. However, this did not appear to influence acceptability of ITCs or RIT. Acceptability of ITCs and RIT was linked to acceptability of AaCP routine vector control activities. However, uptake and use were not always an indication of acceptability. Factors leading to acceptability may be best identified using qualitative methods, but more research is needed on the concept of acceptability and its measurement.

'It's good enough': Swedish general dental practitioners on reasons for accepting substandard root filling quality.

PubMed

Dahlström, L; Lindwall, O; Rystedt, H; Reit, C

2018-04-01

The concept of 'good enough' is central and necessary in the assessment of root filling quality. The aim was to explore the concept by analysing reasons and arguments for the acceptance or rejection of substandard root filling quality as reported by general dental practitioners (GDPs) in Sweden. The study was designed as a qualitative and exploratory study based on seven videotaped focus group interviews analysed by means of qualitative content analysis. Thirty-three GDPs employed in the Public Dental Health Service in Gothenburg, Sweden, participated (4-6 GDPs/interview). In all, nine predetermined questions were followed. Before each focus group, the participants received radiographs of 37 root fillings and were asked to assess the root filling quality. The three cases representing the most divergent assessments served as a basis for the discussion. The cases were presented without clinical information; the dentists would relate to the cases as being just root filled by themselves. The radiographs did not provide a sufficient basis for decisions on whether or not to accept the root filling. This study emphasized that dentists did not primarily look for these arguments in the technical details of the root filling per se, but instead, they considered selected features of the contextual situation. The GDPs constantly introduced relevant 'ad hoc considerations' to account for the decisions they made. These contextual considerations were related to aspects of pulpal and periapical disease, risks (e.g. technical complications) or to consumed resources (personal and/or economic). It was obvious that the concept of 'good enough' does not exist as a general formula ready to be applied in particular situations. Instead, it is necessarily and irremediably tied to contextual properties that emerge from case to case. © 2017 International Endodontic Journal. Published by John Wiley & Sons Ltd.

Using a Film Intervention in Early Addiction Treatment: a Qualitative Analysis of Process.

PubMed

Bjelland, Ingerid Elgesem; Johansen, Ayna; Darnell, Farnad; Brendryen, Håvar

2017-10-01

There is a need for knowledge about how self-help materials can be made useful in treatment for Substance Abuse Disorders (SUD), as a supplement to ongoing treatment, or as independent tools for change. In this study, we explored the use of self-help films in early addiction treatment, taking into account both patient and therapist perspectives, as well as dyadic functions. We explored how active mechanisms might be related to intervention format and implementation context. A secondary aim was to examine the potential mechanisms related to the specific content of the intervention: mindfulness and acceptance psychoeducation. A qualitative exploratory research design, including a general inductive analytic approach, constructivist grounded theory, and source triangulation features, was used to code and analyze interview material. Emerging themes were developed into concepts, and finally an operational model. Participants included 12 patients and 22 therapists, in in-/outpatient addiction clinics, all in urban areas of Norway. The purpose of the design was empirical grounding of developed concepts, to promote different potential user perspectives (patients' and therapists') and obtain process data. The core concept constructed, "Alliance as experiential process," gives a description of the data where patients and therapists accept or reject the film as a result of an experience process conceptualized as alliance formation. The alliance process model reflects the observation that patients constructed alliances autonomously, while therapists built alliances indirectly through their patients' experiences. Use of a self-help film may be a helpful adjunct to face-to-face therapy for patients who create a personally meaningful attachment to the film. Mindfulness/acceptance may offer one basic framework for such connection to take place.

The Small Aircraft Transportation System Higher Volume Operations (SATS HVO) Flight Experiment

NASA Technical Reports Server (NTRS)

Williams, Daniel M.; Murdoch, Jennifer L.; Adams, Catherine H.

2005-01-01

This paper provides a summary of conclusions from the Small Aircraft Transportation System (SATS) Higher Volume Operations (HVO) Flight Experiment which NASA conducted to determine pilot acceptability of the HVO concept for normal conditions. The SATS HVO concept improves efficiency at non-towered, non-radar airports in Instrument Meteorological Conditions (IMC) while achieving a level of safety equal to today s system. Reported are results from flight experiment data that indicate that the SATS HVO concept is viable. The success of the SATS HVO concept is based on acceptable pilot workload, performance, and subjective criteria when compared to the procedural control operations in use today at non-towered, non-radar controlled airfields in IMC. The HVO Flight Experiment, flown on NASA's Cirrus SR22, used a subset of the HVO Simulation Experiment scenarios and evaluation pilots in order to validate the simulation experiment results. HVO and Baseline (today s system) scenarios flown included: single aircraft arriving for a GPS non-precision approach; aircraft arriving for the approach with multiple traffic aircraft; and aircraft arriving for the approach with multiple traffic aircraft and then conducting a missed approach. Results reveal that all twelve low-time instrument-rated pilots preferred SATS HVO when compared to current procedural separation operations. These pilots also flew the HVO procedures safely and proficiently without additional workload in comparison to today s system (Baseline). Detailed results of pilot flight technical error, and their subjective assessments of workload and situation awareness are presented in this paper.

Concept Test of a Smoking Cessation Smart Case.

PubMed

Comello, Maria Leonora G; Porter, Jeannette H

2018-04-05

Wearable/portable devices that unobtrusively detect smoking and contextual data offer the potential to provide Just-In-Time Adaptive Intervention (JITAI) support for mobile cessation programs. Little has been reported on the development of these technologies. To address this gap, we offer a case report of users' experiences with a prototype "smart" cigarette case that automatically tracks time and location of smoking. Small-scale user-experience studies are typical of iterative product design and are especially helpful when proposing novel ideas. The purpose of the study was to assess concept acceptability and potential for further development. We tested the prototype case with a small sample of potential users (n = 7). Participants used the hardware/software for 2 weeks and reconvened for a 90-min focus group to discuss experiences and provide feedback. Participants liked the smart case in principle but found the prototype too bulky for easy portability. The potential for the case to convey positive messages about self also emerged as a finding. Participants indicated willingness to pay for improved technology (USD $15-$60 on a one-time basis). The smart case is a viable concept, but design detail is critical to user acceptance. Future research should examine designs that maximize convenience and that explore the device's ability to cue intentions and other cognitions that would support cessation. This study is the first to our knowledge to report formative research on the smart case concept. This initial exploration provides insights that may be helpful to other developers of JITAI-support technology.

Frameworks of reference: How (some) college students think about biological evolution

NASA Astrophysics Data System (ADS)

Filisky, Michael

1999-12-01

Evolution, a key concept for understanding all of biology, is often misunderstood by students from elementary school to graduate school. In order to teach evolution effectively, as well as to teach the biological concepts necessary for understanding evolution, teachers need to understand the initial ideas that students bring with them to the learning experience. Research has shown that many students are likely to hold alternative conceptions that may block their ability to learn evolution. The goal of this study is to contribute to the effectiveness of teaching evolution at the high school and college levels both by investigating concepts that students bring with them to their first college study of evolution, and by examining the conceptual frameworks that support these students as they construct new understanding. This study was executed in two stages. An initial survey of evolutionary understanding was administered to 203 undergraduate students in two courses at two universities in the area of Boston, MA. The surveys elicited short, written responses to five real and fictitious scenarios about biological inheritance and evolutionary change. Responses were coded into categories of concepts. The data were analyzed for patterns of understanding. Students exhibiting concepts from each of the major categories were randomly selected to participate in the subsequent interview stage of the study. Interviews with six of the students were conducted based on an interview guide employing scenarios similar to those from the survey. Analyses of the interview transcripts included the construction of detailed concept maps for each response followed by narratives of each interviewee's conceptual frameworks. The results of both stages of the study revealed a range of alternative conceptions about evolution, including scientifically acceptable Darwinian ideas and other ideas---including Lamarckian inheritance of acquired characteristics---are not accepted by modern science. The interviews revealed a range of reasoning styles and frameworks that explained how students could find these ideas plausible. The study concludes with recommendations for further research on the understanding of evolutionary topics; for adaptations of the research methods; and for teaching strategies to address the findings.

Acceptability of healthcare interventions: an overview of reviews and development of a theoretical framework.

PubMed

Sekhon, Mandeep; Cartwright, Martin; Francis, Jill J

2017-01-26

It is increasingly acknowledged that 'acceptability' should be considered when designing, evaluating and implementing healthcare interventions. However, the published literature offers little guidance on how to define or assess acceptability. The purpose of this study was to develop a multi-construct theoretical framework of acceptability of healthcare interventions that can be applied to assess prospective (i.e. anticipated) and retrospective (i.e. experienced) acceptability from the perspective of intervention delivers and recipients. Two methods were used to select the component constructs of acceptability. 1) An overview of reviews was conducted to identify systematic reviews that claim to define, theorise or measure acceptability of healthcare interventions. 2) Principles of inductive and deductive reasoning were applied to theorise the concept of acceptability and develop a theoretical framework. Steps included (1) defining acceptability; (2) describing its properties and scope and (3) identifying component constructs and empirical indicators. From the 43 reviews included in the overview, none explicitly theorised or defined acceptability. Measures used to assess acceptability focused on behaviour (e.g. dropout rates) (23 reviews), affect (i.e. feelings) (5 reviews), cognition (i.e. perceptions) (7 reviews) or a combination of these (8 reviews). From the methods described above we propose a definition: Acceptability is a multi-faceted construct that reflects the extent to which people delivering or receiving a healthcare intervention consider it to be appropriate, based on anticipated or experienced cognitive and emotional responses to the intervention. The theoretical framework of acceptability (TFA) consists of seven component constructs: affective attitude, burden, perceived effectiveness, ethicality, intervention coherence, opportunity costs, and self-efficacy. Despite frequent claims that healthcare interventions have assessed acceptability, it is evident that acceptability research could be more robust. The proposed definition of acceptability and the TFA can inform assessment tools and evaluations of the acceptability of new or existing interventions.

Background Computerized cognitive behavioral therapy (cCBT) has been proven to be effective in depression care. Moreover, cCBT packages are becoming increasingly popular. A central aspect concerning the take-up and success of any treatment is its user acceptance. Objective The aim of this study was to update and expand on earlier work on user acceptance of cCBT for depression. Methods This paper systematically reviewed quantitative and qualitative studies regarding the user acceptance of cCBT for depression. The initial search was conducted in January 2016 and involved the following databases: Web of Science, PubMed, the Cochrane Library, and PsycINFO. Studies were retained if they described the explicit examination of the user acceptance, experiences, or satisfaction related to a cCBT intervention, if they reported depression as a primary outcome, and if they were published in German or English from July 2007 onward. Results A total of 1736 studies were identified, of which 29 studies were eligible for review. User acceptance was operationalized and analyzed very heterogeneously. Eight studies reported a very high level of acceptance, 17 indicated a high level of acceptance, and one study showed a moderate level of acceptance. Two qualitative studies considered the positive and negative aspects concerning the user acceptance of cCBT. However, a substantial proportion of reviewed studies revealed several methodical shortcomings. Conclusions In general, people experience cCBT for depression as predominantly positive, which supports the potential role of these innovative treatments. However, methodological challenges do exist in terms of defining user acceptance, clear operationalization of concepts, and measurement. PMID:28903893

Hybrid meat analogues, whereby a proportion of meat has been partially replaced by more sustainable protein sources, have been proposed to provide a means for more sustainable diets in the future. Consumer testing was conducted to determine consumer acceptability of different formulations of Hybrid beef burgers and pork sausages in comparison with both meat and meat-free commercial products. Acceptability data were generated using the 9-point hedonic scale. Check-all-that-apply (CATA) questioning was used to determine the sensory attributes perceived in each product as well as information on the attributes of consumers' ideal products. It was identified that Hybrid products were generally well liked among consumers and no significant differences in consumer acceptability (p > .05) were identified between Hybrid and full meat products, whereas meat-free products were found to be less accepted. However, Hybrid sausages received higher acceptability scores (6.00-6.51) than Hybrid burgers (5.84-5.92) suggesting that format may have a large impact on consumer acceptability of Hybrid products. Correspondence Analysis (CA) indicated that Hybrid products were grouped with meat products in their sensory attributes. Penalty analysis found that a "meaty flavor" was the largest factor driving consumer acceptability in both burgers and sausages. Cluster analysis of consumer acceptability data identified key differences in overall acceptability between different consumer groups (consumers who only eat meat products and consumers who eat both meat and meat-free products). The Hybrid concept was found to bridge the acceptability gap between meat and meat-free products; however, further product reformulation is required to optimize consumer acceptability.

Along with concept developers, the Systems Evaluation and Assessment (SEA) sub-element of VAMS will develop those scenarios and metrics required for testing the new concepts that reside within the System-Level Integrated Concepts (SLIC) sub-element in the VAMS project. These concepts will come from the NRA process, space act agreements, a university group, and other NASA researchers. The emphasis of those concepts is to increase capacity while at least maintaining the current safety level. The concept providers will initially develop their own scenarios and metrics for self-evaluation. In about a year, the SEA sub-element will become responsible for conducting initial evaluations of the concepts using a common scenario and metric set. This set may derive many components from the scenarios and metrics used by the concept providers. Ultimately, the common scenario\\metric set will be used to help determine the most feasible and beneficial concepts. A set of 15 questions and issues, discussed below, pertaining to the scenario and metric set, and its use for assessing concepts, was submitted by the SEA sub-element for consideration during the breakout session. The questions were divided among the three breakout groups. Each breakout group deliberated on its set of questions and provided a report on its discussion.

Little is known about teen fathers though they are found to be disproportionately represented among incarcerated youth. SOURCE USED: This article is developed from a qualitative pilot study of adolescent fathers in the justice system. The authors theorize about teen fathers and the process by which they accept, reject, or are "barriered" from a father identity and role. Adolescence as a developmental period during which an identity is forming is viewed in concert with the concept of hegemonic masculinity and the concept of intersectionality. Risk factors in childhood and adolescence complete the conceptual model through which incarcerated adolescent fathers can be examined. © 2011 Wiley Periodicals, Inc.

Qualitative methods to ensure acceptability of behavioral and social interventions to the target population

PubMed Central

Ayala, Guadalupe X.; Elder, John P.

2013-01-01

This paper introduces qualitative methods for assessing the acceptability of an intervention. Acceptability refers to determining how well an intervention will be received by the target population and the extent to which the new intervention or its components might meet the needs of the target population and organizational setting. In this paper, we focus on two common qualitative methods for conducting acceptability research and their advantages and disadvantages: focus groups and interviews. We provide examples from our own research and other studies to demonstrate the use of these methods for conducting acceptability research and how one might adapt this approach for oral health research. Finally, we present emerging methods for conducting acceptability research, including the use of community-based participatory research, as well as the utility of conducting acceptability research for assessing the appropriateness of measures in intervention research.

Background The desire for hastened death or wish to hasten death (WTHD) that is experienced by some patients with advanced illness is a complex phenomenon for which no widely accepted definition exists. This lack of a common conceptualization hinders understanding and cooperation between clinicians and researchers. The aim of this study was to develop an internationally agreed definition of the WTHD. Methods Following an exhaustive literature review, a modified nominal group process and an international, modified Delphi process were carried out. The nominal group served to produce a preliminary definition that was then subjected to a Delphi process in which 24 experts from 19 institutions from Europe, Canada and the USA participated. Delphi responses and comments were analysed using a pre-established strategy. Findings All 24 experts completed the three rounds of the Delphi process, and all the proposed statements achieved at least 79% agreement. Key concepts in the final definition include the WTHD as a reaction to suffering, the fact that such a wish is not always expressed spontaneously, and the need to distinguish the WTHD from the acceptance of impending death or from a wish to die naturally, although preferably soon. The proposed definition also makes reference to possible factors related to the WTHD. Conclusions This international consensus definition of the WTHD should make it easier for clinicians and researchers to share their knowledge. This would foster an improved understanding of the phenomenon and help in developing strategies for early therapeutic intervention. PMID:26726801

The knowledge and acceptance of the concept of brain death among future health professionals is essential. The objective of this study was to analyze the knowledge of the concept of brain death among nursing students at the Medical University of Warsaw and determine the factors that affect it. Academic year 2011-2012, nursing students of the University of Poland. Sampling points in 5 compulsory-attendance nursing courses with a completion rate >80%. Validated questionnaire (PCID-DTO Rios), anonymous and self-administered. The completion rate was 96% (793/828); 71% (n = 561) knew the concept of brain death, 22% (n = 178) did not know it, and 7% (n = 54) did not know that it implies the death of the patient. Variables related to the correct knowledge: 1) to be studying in 4th year compared with 1st year (85% vs 60%; P ≤ .001); 2) discuss the subject with family (76% vs 61%; P ≤ .001); 3) discuss with friends (73% vs 63%; P = .009); and 4) having a favorable attitude toward organ donation (74% vs 65%; P = .011). In the multivariate analysis, the variables that remained independent were studying in 4th year (odds ratio [OR], 3.809; 95% confidence interval [CI], 2.006-5.823; P ≤ .001) and discussed with family concerning donation and transplantation (OR, 1.718; 95% CI, 1.241-2.381; P ≤ .001). One-third of the nursing students were unfamiliar with the concept of brain death. Copyright © 2016 Elsevier Inc. All rights reserved.

An amendment to the German medical curriculum in April 2002 will place basic practical skills at the centre of medical training. We report here on the implementation and evaluation of an obligatory, tutor-guided, and integrated skills laboratory concept in the field of internal medicine. To test the effectiveness of a skills laboratory training on OSCE performance a pilot study was carried out. The experimental group, of 77 students, participated in seven sessions of communication training, skills laboratory training, and bedside teaching, each lasting one and a half hours. The control group of 66 students had as many sessions but was only offered bedside-teaching. The evaluation of acceptance of skills' training as well as the related increase in individual competence is on-going (summer term 2004: n = 176 students). The integrated skills laboratory concept was rated at 3.5 (SD = 1.2) on a 5-point scale and was acknowledged as practice-oriented (M = 4.2; SD = 1.0) and relevant for doctors' everyday lives (M = 3.6; SD = 1.1). Increased levels of competence according to individual self-evaluations proved to be highly significant (p<.001), and results of the pilot study showed that the experimental group had a significantly better OSCE performance than the control group (p<.001). This pilot study shows that curriculum changes promoting basic clinical skills are effective and lead to an improved practical education of tomorrow's physicians. The integrated skills laboratory concept is well accepted and leads to a relevant increase in competence in the practice of internal medical. The presented skills laboratory concept in internal medicine is proving to be a viable and efficient learning tool.

Evaluation of Head-Worn Display Concepts for Commercial Aircraft Taxi Operations

Previous research has demonstrated that a Head-Up Display (HUD) can be used to enable more capacity and safer aircraft surface operations. This previous research also noted that the HUD exhibited two major limitations which hindered the full potential of the display concept: 1) the monochrome HUD format; and, 2) a limited, fixed field of regard. Full-color Head Worn Displays (HWDs) with very small sizes and weights are emerging to the extent that this technology may be practical for commercial and business aircraft operations. By coupling the HWD with a head tracker, full-color, out-the-window display concepts with an unlimited field-of-regard may be realized to improve efficiency and safety in surface operations. A ground simulation experiment was conducted at NASA Langley to evaluate the efficacy of head-worn display applications which may directly address the limitations of the HUD while retaining all of its advantages in surface operations. The simulation experiment used airline crews to evaluate various displays (HUD, HWD) and display concepts in an operationally realistic environment by using a Chicago, O Hare airport database. The results pertaining to the implications of HWDs for commercial business and transport aviation applications are presented herein. Overall HWD system latency was measured and found to be acceptable, but not necessarily optimal. A few occurrences of simulator sickness were noted while wearing the HWD, but overall there appears to be commercial pilot acceptability and usability to the concept. Many issues were identified which need to be addressed in future research including continued reduction in user encumbrance due to the HWD, and improvement in image alignment, accuracy, and boresighting.

Acceptability of Interventions Delivered Online and Through Mobile Phones for People Who Experience Severe Mental Health Problems: A Systematic Review.

Psychological interventions are recommended for people with severe mental health problems (SMI). However, barriers exist in the provision of these services and access is limited. Therefore, researchers are beginning to develop and deliver interventions online and via mobile phones. Previous research has indicated that interventions delivered in this format are acceptable for people with SMI. However, a comprehensive systematic review is needed to investigate the acceptability of online and mobile phone-delivered interventions for SMI in depth. This systematic review aimed to 1) identify the hypothetical acceptability (acceptability prior to or without the delivery of an intervention) and actual acceptability (acceptability where an intervention was delivered) of online and mobile phone-delivered interventions for SMI, 2) investigate the impact of factors such as demographic and clinical characteristics on acceptability, and 3) identify common participant views in qualitative studies that pinpoint factors influencing acceptability. We conducted a systematic search of the databases PubMed, Embase, PsycINFO, CINAHL, and Web of Science in April 2015, which yielded a total of 8017 search results, with 49 studies meeting the full inclusion criteria. Studies were included if they measured acceptability through participant views, module completion rates, or intervention use. Studies delivering interventions were included if the delivery method was online or via mobile phones. The hypothetical acceptability of online and mobile phone-delivered interventions for SMI was relatively low, while actual acceptability tended to be high. Hypothetical acceptability was higher for interventions delivered via text messages than by emails. The majority of studies that assessed the impact of demographic characteristics on acceptability reported no significant relationships between the two. Additionally, actual acceptability was higher when participants were provided remote online support. Common qualitative factors relating to acceptability were safety and privacy concerns, the importance of an engaging and appealing delivery format, the inclusion of peer support, computer and mobile phone literacy, technical issues, and concerns about the impact of psychological state on intervention use. This systematic review provides an in-depth focus on the acceptability of online and mobile phone-delivered interventions for SMI and identified the need for further research in this area. Based on the results from this review, we recommend that researchers measure both hypothetical and actual acceptability to identify whether initial perceptions of online and mobile phone-delivered interventions change after access. In addition, more focus is needed on the potential impact of demographic and clinical characteristics on acceptability. The review also identified issues with module completion rates and intervention use as measures of acceptability. We therefore advise researchers to obtain qualitative reports of acceptability throughout each phase of intervention development and testing. Further implications and opportunities for future research are discussed.

Hindson, W. S.; Hardy, G. H.; Innis, R. C.

1981-01-01

Flight tests were carried out to assess the feasibility of piloted steep curved, and decelerating approach profiles in powered lift STOL aircraft. Several STOL control concepts representative of a variety of aircraft were evaluated in conjunction with suitably designed flight directions. The tests were carried out in a real navigation environment, employed special electronic cockpit displays, and included the development of the performance achieved and the control utilization involved in flying 180 deg turning, descending, and decelerating approach profiles to landing. The results suggest that such moderately complex piloted instrument approaches may indeed be feasible from a pilot acceptance point of view, given an acceptable navigation environment. Systems with the capability of those used in this experiment can provide the potential of achieving instrument operations on curved, descending, and decelerating landing approaches to weather minima corresponding to CTOL Category 2 criteria, while also providing a means of realizing more efficient operations during visual flight conditions.

Implementation of Good Laboratory Practices (GLP) in basic scientific research: Translating the concept beyond regulatory compliance.

PubMed

Jena, G B; Chavan, Sapana

2017-10-01

The principles of Good Laboratory Practices (GLPs) are mainly intended for the laboratories performing studies for regulatory compliances. However, today GLP can be applied to broad disciplines of science to cater to the needs of the experimental objectives, generation of quality data and assay reproducibility. Considering its significance, it can now be applied in academics; industries as well as government set ups throughout the world. GLP is the best way to promote the reliability, reproducibility of the test data and hence facilitates the international acceptability. Now it is high time to translate and implement the concept of GLP beyond regulatory studies. Thus, it can pave the way for better understanding of scientific problems and help to maintain a good human and environmental health. Through this review, we have made an attempt to explore the uses of GLP principles in different fields of science and its acceptability as well as looking for its future perspectives.

2005-01-01

This paper provides an analysis of Flight Technical Error (FTE) from recent SATS experiments, called the Higher Volume Operations (HVO) Simulation and Flight experiments, which NASA conducted to determine pilot acceptability of the HVO concept for normal operating conditions. Reported are FTE results from simulation and flight experiment data indicating the SATS HVO concept is viable and acceptable to low-time instrument rated pilots when compared with today s system (baseline). Described is the comparative FTE analysis of lateral, vertical, and airspeed deviations from the baseline and SATS HVO experimental flight procedures. Based on FTE analysis, all evaluation subjects, low-time instrument-rated pilots, flew the HVO procedures safely and proficiently in comparison to today s system. In all cases, the results of the flight experiment validated the results of the simulation experiment and confirm the utility of the simulation platform for comparative Human in the Loop (HITL) studies of SATS HVO and Baseline operations.

The present study examines the concept of illness identity, the degree to which a chronic illness is integrated into one's identity, in adults with a chronic illness by validating a new self-report questionnaire, the Illness Identity Questionnaire (IIQ). Self-report questionnaires on illness identity, psychological, and physical functioning were assessed in two samples: adults with congenital heart disease (22-78 year old; n = 276) and with multisystem connective tissue disorders (systemic lupus erythematosus or systemic sclerosis; 17-81 year old; n = 241). The IIQ could differentiate four illness identity states (i.e., engulfment, rejection, acceptance, and enrichment) in both samples, based on exploratory and confirmatory factor analysis. All four subscales proved to be reliable. Rejection and engulfment were related to maladaptive psychological and physical functioning, whereas acceptance and enrichment were related to adaptive psychological and physical functioning. The present findings underscore the importance of the concept of illness identity. The IIQ, a self-report questionnaire, is introduced to measure four different illness identity states in adults with a chronic illness.

2012-11-01

To understand neonatologists' attitudes toward end-of-life (EOL) management in clinical scenarios, EOL ethical concepts and resource utilization. American Academy of Pediatrics (AAP) Perinatal section members completed an anonymous online survey. Respondents indicated preferences in limiting life-sustaining treatments in four clinical scenarios, ranked agreement with EOL-care ethics statements, indicated outside resources previously used and provided demographic information. In all, 451 surveys were analyzed. Across clinical scenarios and as general ethical concepts, withdrawal of mechanical ventilation in severely affected patients was most accepted by respondents; withdrawal of artificial nutrition and hydration was least accepted. One-third of neonatologists did not agree that non-initiation of treatment is ethically equivalent to withdrawal. Around 20% of neonatologists would not defer care if uncomfortable with a parent's request. Respondents' resources included ethics committees, AAP guidelines and legal counsel/courts. Challenges to providing just, unified EOL care strategies are discussed, including deferring care, limiting artificial nutrition/hydration and conditions surrounding ventilator withdrawal.

Several concepts have been developed related to development and deployment lunar exploration vehicles and assets that provide critical functionality such as transportation, habitation, and communication, to name a few. Together, these systems perform complex safety-critical functions, largely dependent on avionics for control and behavior of system functions. These functions are implemented using interchangeable, modular avionics designed for lunar transit and lunar surface deployment. Systems are optimized towards reuse and commonality of form and interface and can be configured via software or component integration for special purpose applications. There are two core concepts in the reference avionics architecture described in this report. The first concept uses distributed, smart systems to manage complexity, simplify integration, and facilitate commonality. The second core concept is to employ extensive commonality between elements and subsystems. These two concepts are used in the context of developing reference designs for many lunar surface exploration vehicles and elements. These concepts are repeated constantly as architectural patterns in a conceptual architectural framework. This report describes the use of these architectural patterns in a reference avionics architecture for Lunar surface systems elements.

The relative advantages of STOL aircraft concepts were examined by simulating the operations of a short haul high-density intercity STOL system set in two arenas, the California corridor and the Chicago-Detroit-Cleveland triangle, during the 1980 time period. The study was constrained to the use of three aircraft concepts designated as the deflected slipstream turboprop, externally blown flap, and augmentor wing turbofan configurations. The projected demographic, economic, travel demand, and travel characteristics of the representative arenas were identified. The STOL airline operating scenarios were then formulated and through the use of the aerospace modal split simulation program, the traveler modal choices involving alternative STOL concepts were estimated in the context of the total transportation environment for 1980. System combinations that presented the best potential for economic return and traveler acceptance were then identified for each STOL concept.

Pain and suffering as viewed by the Hindu religion.

Religion and spiritual practices are among the resources used by patients to cope with chronic pain. The major concepts of Hinduism that are related to pain and suffering are presented. Ways that Hindu traditions deal with pain and suffering are reviewed, including the concept of acceptance, which has been studied in the pain medicine literature. By becoming more familiar with Hindu views of pain and suffering, pain medicine practitioners can offer potentially helpful concepts to all patients and support Hindus' spirituality as it relates to pain and suffering. Religion or spirituality is often important to patients. This article will inform the pain medicine practitioner how pain and suffering are viewed in Hinduism, the third largest religion in the world. It is hoped that these concepts will prove helpful when treating not only followers of Hinduism but all patients.

This paper explores three questions related to acceptance as a security management approach. Acceptance draws upon relationships with community members, authorities, belligerents and other stakeholders to provide consent for the presence and activities of a non-governmental organisation (NGO), thereby reducing threats from these actors. Little is documented about how NGOs gain and maintain acceptance, how they assess and monitor the presence and degree of acceptance, or how they determine whether acceptance is effective in a particular context. Based on field research conducted in April 2011 in Kenya, South Sudan and Uganda, we address each of these three issues and argue that acceptance must be actively sought as both a programme and a security management strategy. In the paper we delineate elements common to all three contexts as well as missed opportunities, which identify areas that NGOs can and should address as part of an acceptance approach. © 2015 The Author(s).

The number of commercial aircraft operations is predicted to increase in the next ten years, creating a need for improved operational efficiency. Two areas believed to offer significant increases in efficiency are optimized profile descents and dependent parallel runway operations. It is envisioned that during both of these types of operations, flight crews will precisely space their aircraft behind preceding aircraft at air traffic control assigned intervals to increase runway throughput and maximize the use of existing infrastructure. This paper describes a human-in-the-loop experiment designed to study the performance of an onboard spacing algorithm and pilots ratings of the usability and acceptability of an airborne spacing concept that supports dependent parallel arrivals. Pilot participants flew arrivals into the Dallas Fort-Worth terminal environment using one of three different simulators located at the National Aeronautics and Space Administration s (NASA) Langley Research Center. Scenarios were flown using Interval Management with Spacing (IM-S) and Required Time of Arrival (RTA) control methods during conditions of no error, error in the forecast wind, and offset (disturbance) to the arrival flow. Results indicate that pilots delivered their aircraft to the runway threshold within +/- 3.5 seconds of their assigned arrival time and reported that both the IM-S and RTA procedures were associated with low workload levels. In general, pilots found the IM-S concept, procedures, speeds, and interface acceptable; with 92% of pilots rating the procedures as complete and logical, 218 out of 240 responses agreeing that the IM-S speeds were acceptable, and 63% of pilots reporting that the displays were easy to understand and displayed in appropriate locations. The 22 (out of 240) responses, indicating that the commanded speeds were not acceptable and appropriate occurred during scenarios containing wind error and offset error. Concerns cited included the occurrence of multiple speed changes within a short time period, speed changes required within twenty miles of the runway, and an increase in airspeed followed shortly by a decrease in airspeed. Within this paper, appropriate design recommendations are provided, and the need for continued, iterative human-centered design is discussed.

A problem commonly encountered in programs for prevention of mother-to-child-transmission (PMTCT) of HIV in sub-Saharan Africa is low rates of HIV test acceptance among pregnant women. In this study, we examined risk factors and reasons for HIV test refusal among 432 women attending three antenatal care clinics offering PMTCT in urban and semi-urban parts of the Mbarara district, Uganda. Structured interviews were performed following pre-test counselling. Three-hundred-eighty women were included in the study, 323 (85%) of whom accepted HIV testing. In multivariate analysis, testing site (Site A: OR = 1.0; Site B: OR = 3.08; 95%CI: 1.12-8.46; Site C: OR = 5.93; 95%CI: 2.94-11.98), age between 30 and 34 years (<20 years: OR = 1.0; 20-24 years: OR = 1.81; 95%CI: 0.58-5.67; 25-29 years: OR = 2.15; 95%CI: 0.66-6.97; 30-34 years: OR = 3.88; 95%CI: 1.21-13.41), mistrust in reliability of the HIV test (OR = 20.60; 95%CI: 3.24-131.0) and not having been tested for HIV previously (OR = 2.15; 95%CI: 1.02-4.54) were associated with test refusal. Testing sites operating for longer durations had higher rates of acceptance. The most common reasons claimed for test refusal were: lack of access to antiretroviral therapy (ART) for HIV-infected women (88%; n=57), a need to discuss with partner before decision (82%; n=57) and fear of partner's reaction (54%; n=57). Comparison with previous periods showed that the acceptance rate increased with the duration of the program. Our study identified risk factors for HIV test refusal among pregnant women in Uganda and common reasons for not accepting testing. These findings may suggest modifications and improvements in the performance of HIV testing in this and similar populations.

Three structural concepts are studied: (1) a state-of-the-art insulated aluminum skin-stringer structure; (2) a near-art insulated evacuated aluminum-alloy honeycomb structure; and (3) an advanced evacuated Rene 41 honeycomb hot structure. Each is evaluated for its thermostructural performance for each of the flight profiles (ascent, entry, and a recall or abort). Results indicate that (1) the state-of-the-art structure encounters negligible thermal stress; (2) the near-art structure has acceptable thermal stresses; and (3) the advanced structure will have thermal stress levels above the material allowables.

1981-01-01

An electronic flight-guidance display format was designed for use in evaluations of the collimated head-up display concept in low-visibility landings of transport aircraft. In the design process of iterative evaluation and modification, some general principles, or guidelines, applicable to such flight displays were suggested. The usefulness of an indication of instantaneous inertial flightpath was clearly demonstrated, particularly in low-altitude transition to visual references. Evaluator pilot acceptance of the unfamiliar display concepts was very positive when careful attention was given to indoctrination and training.

In Pakistan, patients with chronic kidney disease (CKD) are commonly diagnosed at a late stage. There is little information about the refusal of hemodialysis by hospitalized CKD patients who need hemodialysis (HD) and reasons for acceptance and refusal among these patients. All patients with Stage V CKD who had medical indications to undergo HD and were hospitalized at a tertiary care facility over a six-month period were invited to participate in this study. Patients were surveyed regarding acceptance or refusing of HD and reasons for their decisions. Demographic, socioeconomic, and clinical characteristics of patients were compared between patients who accepted or refused HD. A total of 125 patients were included in the study. The mean age of the patients was 47.9 ±12.1 years. The mean duration of diagnosis of CKD was 2.5 ± 0.6 months. Of all patients, 72 (57.6%) agreed to do HD and 53 (42.4%) refused HD. Patients with arteriovenous fistula in place (27.1 vs. 9.1%, P 0.02) and those in the middle- or higher-income group (64.4% vs. 38.6%, p = 0.03) were more willing to undergo HD. Trust in doctor's advice (86.1%) was the most common reason for acceptance of HD. Frequency of HD per week (52.8%), lifelong and permanent nature of HD (50.9%), advice by family members or friends (37.7%), perception of poor quality of life on HD (35.8%), and fear of HD needles and complications during HD (33.9%) were the most common reasons for refusal. Refusal of HD is common among hospitalized CKD patients with medical indications to undergo HD, especially in lower income group.

Targeting different smoking cessation programs to smokers most likely to quit when using them could reduce the burden of lung disease. To identify smokers most likely to quit using pure reward-based financial incentives or incentive programs requiring refundable deposits to become eligible for rewards. We conducted prespecified secondary analyses of a randomized trial in which 2,538 smokers were assigned to an $800 reward contingent on sustained abstinence from smoking, a refundable $150 deposit plus a $650 reward, or usual care. Using logistic regression, we identified characteristics of smokers that were most strongly associated with accepting their assigned intervention and ceasing smoking for 6 months. We assessed modification of the acceptance, efficacy, and effectiveness of reward and deposit programs by 11 prospectively selected demographic, smoking-related, and psychological factors. Predictors of sustained smoking abstinence differed among participants assigned to reward- versus deposit-based incentives. However, greater readiness to quit and less steep discounting of future rewards were consistently among the most important predictors. Deposit-based programs were uniquely effective relative to usual care among men, higher-income participants, and participants who more commonly failed to pay their bills (all interaction P values < 0.10). Relative to rewards, deposits were more effective among black persons (P = 0.022) and those who more commonly failed to pay their bills (P = 0.082). Relative to rewards, deposits were more commonly accepted by higher-income participants, men, white persons, and those who less commonly failed to pay their bills (all P < 0.05). Heterogeneity among smokers in their acceptance and response to different forms of incentives suggests potential benefits of targeting behavior-change interventions based on patient characteristics.

Details of a proposed test program for PV thin-film modules which the Department of Energy has directed the Solar Energy Research Institute (SERI) to prepare are presented. Results of one of the characterization tests that SERI has performed are also presented. The objective is to establish a common approach to testing modules that will be acceptable to both users and manufacturers. The tests include acceptance, qualification, and characterization tests. Acceptance tests verify that randomly selected modules have similar characteristics. Qualification tests are based on accelerated test methods designed to simulate adverse conditions. Characterization tests provide data on performance in a predefined environment.

Euthanasia is legal in Belgium if due care criteria are met, which is judged by committees including physicians, ethicists, and jurists. We examined whether students in these disciplines differ in how they judge euthanasia as an acceptable act. A cross-sectional, anonymous e-mail survey revealed that they have similar attitudes and accept its legalization. Therefore, joint decision-making of physicians, ethicists, and lawyers regarding euthanasia seems to have a common attitudinal base in Belgium. However, they differ to some extent regarding the conditions they put forward for euthanasia being acceptable. Philosophy of life (religion) was an independent predictor of these attitudes.

Gender-Blind Sexism and Rape Myth Acceptance.

The purpose of this article is to explore whether gender-blind sexism, as an extension of Bonilla-Silva's racialized social system theory, is an appropriate theoretical framework for understanding the creation and continued prevalence of rape myth acceptance. Specifically, we hypothesize that individuals who hold attitudes consistent with the frames of gender-blind sexism are more likely to accept common rape myths. Data for this article come from an online survey administered to the entire undergraduate student body at a large Midwestern institution (N = 1,401). Regression analysis showed strong support for the effects of gender-blind sexism on rape myth acceptance. © The Author(s) 2016.
