Vaccine testing for emerging infections: the case for individual randomisation

PubMed Central

Eyal, Nir; Lipsitch, Marc

2017-01-01

During the 2014–2015 Ebola outbreak in Guinea, Liberia and Sierra Leone, many opposed the use of individually randomised controlled trials to test candidate Ebola vaccines. For a raging fatal disease, they explained, it is unethical to relegate some study participants to control arms. In Zika and future emerging infections, similar opposition may hinder urgent vaccine research, so it is best to address these questions now. This article lays out the ethical case for individually randomised control in testing vaccines against many emerging infections, including lethal infections in low-income countries, even when at no point in the trial do the controls receive the countermeasures being tested. When individual randomisation is feasible—and it often will be—it tends to save more lives than alternative designs would. And for emerging infections, individual randomisation also tends as such to improve care, access to the experimental vaccine and prospects for all participants relative to their opportunities absent the trial, and no less than alternative designs would. That obtains even under placebo control and without equipoise—requiring which would undermine individual randomisation and the alternative designs that opponents proffered. Our arguments expound four often-neglected factors: benefits to non-participants, benefits to participants once a trial is over including post-trial access to the study intervention, participants’ prospects before randomisation to arms and the near-inevitable disparity between arms in any randomised controlled trial.

This article is a complement to “A Template for Non-Religious-Based Discussions Against Euthanasia” by Melissa Harintho, Nathaniel Bloodworth, and E. Wesley Ely which appeared in the February 2015 Linacre Quarterly. Herein we build upon Daniel Sulmasy's opening and closing arguments from the 2014 Intelligence Squared debate on legalizing assisted suicide, supplemented by other non-faith-based arguments and thoughts, providing four nontheistic arguments against physician-assisted suicide and euthanasia: (1) “it offends me”; (2) slippery slope; (3) “pain can be alleviated”; (4) physician integrity and patient trust. Lay Summary: Presented here are four non-religious, reasonable arguments against physician-assisted suicide and euthanasia: (1) “it offends me,” suicide devalues human life; (2) slippery slope, the limits on euthanasia gradually erode; (3) “pain can be alleviated,” palliative care and modern therapeutics more and more adequately manage pain; (4) physician integrity and patient trust, participating in suicide violates the integrity of the physician and undermines the trust patients place in physicians to heal and not to harm.

"What the patient wants…": Lay attitudes towards end-of-life decisions in Germany and Israel.

2015-08-01

National legislation, as well as arguments of experts, in Germany and Israel represent opposite regulatory approaches and positions in bioethical debates concerning end-of-life care. This study analyzes how these positions are mirrored in the attitudes of laypeople and influenced by the religious views and personal experiences of those affected. We qualitatively analyzed eight focus groups in Germany and Israel in which laypeople (religious, secular, affected, and non-affected) were asked to discuss similar scenarios involving the withholding or withdrawing of treatment, physician-assisted suicide, and euthanasia. In both countries, respect for patient autonomy and patients' wishes to die with dignity found broad consent. Laypeople argued in favor of accepting such wishes when they were put down in an advance directive. Laypeople in non-religious groups in both countries argued on the basis of a respect for autonomy for the possibility of euthanasia in severe cases but, at the same time, cautioned against its possible misuse. National contrast was apparent in the moral reasoning of lay respondents concerning the distinction between withholding and withdrawing treatment. The modern religious laypeople in Israel, especially, argued strongly, on the basis of the halakhic tradition, against allowing the withdrawal of treatment in accord with a patient's wish. We conclude by discussing the emergent notion of shared responsibility and views of professional responsibility, which we connect through relevant cultural themes such as religion and national culture.

Too Many Rationales, Not Enough Reason: A Call to Examine the Goals of Including Lay Members on Institutional Review Boards.

PubMed

Solomon, Stephanie

2016-01-01

Every major U.S. commission appointed to review Institutional Review Boards (IRBs) as well as numerous reports and scholarly articles have recommended increasing the number of lay (nonscientist and unaffiliated) members on IRBs. Meanwhile, qualitative studies have shown that lay IRB members experience confusion about their roles, including ambiguity whether their roles are different from other members of the board. Without articulating the unique reasons why unaffiliated and nonscientist members are needed, IRBs have little guidance on how to recruit and train these members, and how many should be at the table. By looking back through the history of IRB regulations, policies, and commentaries we can articulate unique contributions these members can make. Only with these contributions in mind can we make arguments for how to best achieve them and make the case that increasing their numbers is necessary.

This paper introduces adult basic life support (BLS) guidelines for lay rescuers of the resuscitation council of Asia (RCA) developed for the first time. The RCA BLS guidelines for lay rescuers have been established by expert consensus among BLS Guidelines Taskforce of the RCA on the basis of the 2015 International Consensus on Cardiopulmonary Resuscitation (CPR) and Emergency Cardiovascular Care Science with Treatment Recommendations. The RCA recommends compression-only CPR for lay rescuers and emphasizes high-quality CPR with chest compression depth of approximately 5cm and chest compression rate of 100-120min(-1). Role of emergency medical dispatchers in helping lay rescuers recognize cardiac arrest and perform CPR is also emphasized. The RCA guidelines will contribute to help Asian countries establish and implement their own CPR guidelines in the context of their domestic circumstances. Copyright © 2016 Elsevier Ireland Ltd.

Uganda currently has no organized prehospital emergency system. We sought to measure the current burden of injury seen by lay people in Kampala, Uganda and to determine the feasibility of a lay first-responder training program. We conducted a cross-sectional survey of current prehospital care providers in Kampala: police officers, minibus taxi drivers, and Local Council officials, and collected data on types and frequencies of emergencies witnessed, barriers to aid provision, history of training, and current availability of first-aid supplies. A context-appropriate course on basic first-aid for trauma was designed and implemented. We measured changes in trainees' fund of knowledge before and after training. A total of 309 lay people participated in the study, and during the previous 6 months saw 18 traumatic emergencies each; 39% saw an injury-related death. The most common injury mechanisms were road crashes, assault, and burns. In these cases, 90% of trainees provided some aid, most commonly lifting (82%) or transport (76%). Fifty-two percent of trainees had previous first-aid training, 44% had some access to equipment, and 32% had ever purchased a first-aid kit. Before training, participants answered 45% of test questions correctly (mean %) and this increased to 86% after training (p < 0.0001). Lay people witness many emergencies and deaths in Kampala, Uganda and provide much needed care but are ill-prepared to do so. A context-appropriate prehospital trauma care course can be developed and improve lay people's knowledge of basic trauma care. The effectiveness of such a training program needs to be evaluated prospectively.

The need for true controversies in psychoanalysis: the debates on Melanie Klein and Jacques Lacan in the Rio de la Plata.

PubMed

Bernardi, Ricardo

2002-08-01

Controversies are part of the process of scientific knowing. In psychoanalysis, the diversity of theoretical, technical and epistemological positions makes the debate particularly necessary and by the same token difficult. In this paper, the author examines the function of controversies and the obstacles to their development, taking as examples the debates held in the Río de la Plata (Buenos Aires and Montevideo) during the nineteen seventies, when the dominant Kleinian ideas came into contact with Lacanian thought. The author examines different examples of argumentative discourses, using concepts taken from the theory of argumentation. The major difficulties encountered did not hinge on characteristics pertaining to psychoanalytic theories (i.e. the lack of commensurability between them), but on the defensive strategies aimed at keeping each theory's premises safe from the opposing party's arguments. A true debate implies the construction of a shared argumentative field that makes it possible to lay out the different positions and see some interaction between them and is guided by the search for the best argument. When this occurs, controversies promote the discipline's development, even when they fail to reach any consensus.

Video calls from mobile phones can improve communication during medical emergencies. Lay bystanders can be instructed and supervised by health professionals at Emergency Medical Communication Centers. Before implementation of video mobile calls in emergencies, issues of information security should be addressed. Information security was assessed for risk, based on the information security standard ISO/IEC 27005:2008. A multi-professional team used structured brainstorming to find threats to the information security aspects confidentiality, quality, integrity, and availability. Twenty security threats of different risk levels were identified and analyzed. Solutions were proposed to reduce the risk level. Given proper implementation, we found no risks to information security that would advocate against the use of video calls between lay bystanders and Emergency Medical Communication Centers. The identified threats should be used as input to formal requirements when planning and implementing video calls from mobile phones for these call centers.

"Validity" and "liceity" in conjugal acts: A reply to Stephen Napier on the HIV-condom debate.

PubMed

Arias, Joseph

2016-08-01

Stephen Napier has argued against the soundness of what he calls the "Canon-Law argument" against the moral permissibility of a couple employing a condom for the sake of one spouse avoiding the contraction of HIV from the other spouse. Without an attempt to provide a full defense of the Canon-Law argument per se, this paper argues that Napier has not shown that argument to be inadequate. Napier's critique of that argument suffers from unsubstantiated counterexamples and from a failure to take into account analogous senses of "procreative end" in reference to the conjugal act. Using magisterial documents and canonical sources, this paper suggests that the distinction between validity and liceity can be usefully applied to conjugal acts. Lay Summary: Stephen Napier has argued in favor of the claim that there is no plausible argument for thinking that married couples who use a condom in order to prevent HIV transmission are necessarily doing something morally wrong. In responding to Napier by showing that his arguments in favor of his claim are inconclusive, this article introduces a distinction, frequently used in sacramental theology, between validity and liceity (lawfulness) and applies this distinction to marital actions. I argue that some modifications to martial actions make them merely unlawful, whereas other modifications-such as using an intact condom-make them both unlawful and "invalid."

Impact of a Household Environmental Intervention Delivered by Lay Health Workers on Asthma Symptom Control in Urban, Disadvantaged Children With Asthma

Objectives. We examined whether a home-based educational and environmental intervention delivered by lay health educators would improve asthma symptom control in inner-city children with asthma. Methods. Children 2 to 16 years of age with diagnosed asthma and at least 1 asthma-related hospitalization or 2 emergency visits in the prior year were randomly assigned into 2 groups (immediate and delayed intervention) in a crossover study. Each group participated in the active phase (intervention) and the inactive phase. Outcomes included asthma symptoms, albuterol use, emergency department visits, hospitalizations, and trigger reduction. Results. A total of 264 primarily Black (94%) children were enrolled. The mean number of emergency visits decreased by 30% and inpatient visits decreased by 53% (P < .001) after the intervention. Reductions were seen in pests, presence of carpets in bedrooms, and dust. Nighttime wheezing was significantly reduced after the intervention in both groups (P < .001). Conclusions. Lay health educators effectively reduced asthma triggers and increased caregiver asthma knowledge, which resulted in reduced emergency department visits, hospitalizations, and asthma symptoms. The relationships formed between the caregivers and the lay health educators appeared to positively impact asthma outcomes in this disadvantaged population. PMID:19890172

Co-Production at the Strategic Level: Co-Designing an Integrated Care System with Lay Partners in North West London, England

Morton, Michael

2016-01-01

In North West London, health and social care leaders decided to design a system of integrated care with the aim of improving the quality of care and supporting people to maintain independence and participation in their community. Patients and carers, known as ‘lay partners,’ were to be equal partners in co-production of the system. Lay partners were recruited by sending a role profile to health, social care and voluntary organisations and requesting nominations. They formed a Lay Partners Advisory Group from which pairs were allocated to system design workstreams, such as which population to focus on, financial flow, information technology and governance. A larger and more diverse Lay Partners Forum provided feedback on the emerging plans. A key outcome of this approach was the development of an integration toolkit co-designed with lay partners. Lay partners provided challenge, encouraged innovation, improved communication, and held the actions of other partners to account to ensure the vision and aims of the emerging integrated care system were met. Key lessons from the North West London experience for effective co-production include: recruiting patients and carers with experience of strategic work; commitment to the vision; willingness to challenge and to listen; strong connections within the community being served; and enough time to do the work. Including lay partners in co-design from the start, and at every level, was important. Agreeing the principles of working together, providing support and continuously recruiting lay representatives to represent their communities are keys to effective co-production. PMID:27616958

In search of the cancer candidate: can lay epidemiology help?

PubMed

Macdonald, Sara; Watt, Graham; Macleod, Una

2013-05-01

First published in 1991, the ideas embedded in 'Lay epidemiology and the prevention paradox' offered a novel and rational explanation for the lay public's failure to fully engage with the lifestyle messages offered by health educators. During the course of a large ethnographic study in South Wales, Davison and colleagues described the emergence of what they termed the coronary candidate. Candidacy provides a 'cultural mechanism' that facilitates the estimation of risk for coronary heart disease. The model has rarely been applied to other major illnesses. This article presents findings from a study that sought to explore the lay epidemiology model, candidacy and cancer. In a series of in-depth individual interviews, members of the lay public discussed their ideas about cancer, and what emerged was an explanatory hierarchy to account for cancer events. Yet the random and unpredictable nature of cancer was emphasised as well as a general reluctance to accept the idea of cancer candidacy. © 2012 The Authors.

Public Claims about Automatic External Defibrillators: An Online Consumer Opinions Study

PubMed Central

2011-01-01

Background Patients are no longer passive recipients of health care, and increasingly engage in health communications outside of the traditional patient and health care professional relationship. As a result, patient opinions and health related judgements are now being informed by a wide range of social, media, and online information sources. Government initiatives recognise self-delivery of health care as a valuable means of responding to the anticipated increased global demand for health resources. Automated External Defibrillators (AEDs), designed for the treatment of Sudden Cardiac Arrest (SCA), have recently become available for 'over the counter' purchase with no need for a prescription. This paper explores the claims and argumentation of lay persons and health care practitioners and professionals relating to these, and how these may impact on the acceptance, adoption and use of these devices within the home context. Methods We carry out a thematic content analysis of a novel form of Internet-based data: online consumer opinions of AED devices posted on Amazon.com, the world's largest online retailer. A total of #83 online consumer reviews of home AEDs are analysed. The analysis is both inductive, identifying themes that emerged from the data, exploring the parameters of public debate relating to these devices, and also driven by theory, centring around the parameters that may impact upon the acceptance, adoption and use of these devices within the home as indicated by the Technology Acceptance Model (TAM). Results Five high-level themes around which arguments for and against the adoption of home AEDs are identified and considered in the context of TAM. These include opinions relating to device usability, usefulness, cost, emotional implications of device ownership, and individual patient risk status. Emotional implications associated with AED acceptance, adoption and use emerged as a notable factor that is not currently reflected within the existing TAM. Conclusions The value, credibility and implications of the findings of this study are considered within the context of existing AED research, and related to technology acceptance theory. From a methodological perspective, this study demonstrates the potential value of online consumer reviews as a novel data source for exploring the parameters of public debate relating to emerging health care technologies.

Drosophila suzukii is threatening soft fruit production worldwide due to the females’ ability to pierce through the intact skin of ripe fruits and lay eggs inside. Larval consumption and the associated microbial infection cause rapid fruit degradation, thus drastic yield and economic loss. Cultivars that limit the proliferation of flies may be ideal to counter this pest; however, they have not yet been developed or identified. To search for potential breeding material, we investigated the rate of adult D. suzukii emergence from individual fruits (fly emergence) of 107 accessions of Fragaria species that had been exposed to egg-laying D. suzukii females. We found significant variation in fly emergence across strawberries, which correlated with accession and fruit diameter, and to a lesser extent with the strawberry species background. We identified accessions with significantly reduced fly emergence, not explained by their fruit diameter. These accessions constitute valuable breeding material for strawberry cultivars that limit D. suzukii spread. PMID:28066452

Methods for solving reasoning problems in abstract argumentation – A survey

Charwat, Günther; Dvořák, Wolfgang; Gaggl, Sarah A.; Wallner, Johannes P.; Woltran, Stefan

2015-01-01

Within the last decade, abstract argumentation has emerged as a central field in Artificial Intelligence. Besides providing a core formalism for many advanced argumentation systems, abstract argumentation has also served to capture several non-monotonic logics and other AI related principles. Although the idea of abstract argumentation is appealingly simple, several reasoning problems in this formalism exhibit high computational complexity. This calls for advanced techniques when it comes to implementation issues, a challenge which has been recently faced from different angles. In this survey, we give an overview on different methods for solving reasoning problems in abstract argumentation and compare their particular features. Moreover, we highlight available state-of-the-art systems for abstract argumentation, which put these methods to practice. PMID:25737590

Social argumentation in online synchronous communication

NASA Astrophysics Data System (ADS)

Angiono, Ivan

In education, argumentation has an increasing importance because it can be used to foster learning in various fields including philosophy, history, sciences, and mathematics. Argumentation is also at the heart of scientific inquiry. Many educational technology researchers have been interested in finding out how technologies can be employed to improve students' learning of argumentation. Therefore, many computer-based tools or argumentation systems have been developed to assist students in their acquisition of argumentation skills. While the argumentation systems incorporating online debating tools present a good resource in formal settings, there is limited research revealing what argumentative skills students are portraying in informal online settings without the presence of a moderator. This dissertation investigates the nature of argumentative practices in a massively multiplayer online game where the system successfully incorporates the authentic use of online synchronous communication tools and the patterns that emerge from the interplay between a number of contextual variables including synchronicity, interest, authenticity, and topical knowledge.

Though road traffic injuries (RTIs) are a major cause of mortality in East Africa, few countries have emergency medical services. The aim was to create a sustainable and efficient prehospital lay first responder program, creating a system with lay first responders spread through the 53 motorcycle taxi stages of Iganga Municipality. One hundred and fifty-four motorcycle taxi riders were taught a first aid curriculum in partnership with a local Red Cross first aid trainer and provided with a first aid kit following WHO guidelines for basic first aid. Pre- and post-survey tests measured first aid knowledge improvement over the course. Post-implementation incident report forms were collected from lay first responders after each patient encounter over 6 months. Follow-up interviews were conducted with 110 of 154 trainees, 9 months post-training. Improvement was measured across all five major first aid categories: bleeding control (56.9 vs. 79.7%), scene management (37.6 vs. 59.5%), airway and breathing (43.4 vs. 51.6%), recovery position (13.1 vs. 43.4%), and victim transport (88.2 vs. 94.3%). From the incident report findings, first responders treated 250 victims (82.8% RTI related) and encountered 24 deaths (9.6% of victims). Of the first aid skills, bleeding control and bandaging was used most often (55.2% of encounters). Lay first responders provided transport in 48.3% of encounters. Of 110 lay first responders surveyed, 70 of 76 who had used at least one skill felt "confident" in the care they provided. A prehospital care system composed of lay first responders can be developed leveraging existing transport organizations, offering a scalable alternative for LMICs, demonstrating usefulness in practice and measurable educational improvements in trauma skills for non-clinical lay responders.

Paul Natorp and the emergence of anti-psychologism in the nineteenth century.

PubMed

Edgar, Scott

2008-03-01

This paper examines the anti-psychologism of Paul Natorp, a Marburg School Neo-Kantian. It identifies both Natorp's principle argument against psychologism and the views underlying the argument that give it its force. Natorp's argument depends for its success on his view that certain scientific laws constitute the intersubjective content of knowledge. That view in turn depends on Natorp's conception of subjectivity, so it is only against the background of his conception of subjectivity that his reasons for rejecting psychologism make sense. This interpretation of Natorp suggests that attention paid to late nineteenth century theories of subjectivity and philosophy of psychology could improve our understanding of the emergence of anti-psychologism in that period.

Dispatch of lay volunteers trained in cardiopulmonary resuscitation (CPR) and equipped with automated external defibrillators (AEDs) may improve survival in cases of out-of-hospital cardiac arrest (OHCA). The aim of this study was to investigate the functionality and performance of a smartphone application for locating and alerting nearby trained laymen/women in cases of OHCA. A system using a smartphone application activated by Emergency Dispatch Centres was used to locate and alert laymen/women to nearby suspected OHCAs. Lay responders were instructed either to perform CPR or collect a nearby AED. An online survey was carried out among the responders. From February to August 2016, the system was activated in 685 cases of suspected OHCA. Among these, 224 cases were Emergency Medical Services (EMSs)-treated OHCAs (33%). EMS-witnessed cases (n = 11) and cases with missing survey data (n = 15) were excluded. In the remaining 198 OHCAs, lay responders arrived at the scene in 116 cases (58%), and prior to EMSs in 51 cases (26%). An AED was attached in 17 cases (9%) and 4 (2%) were defibrillated. Lay responders performed CPR in 54 cases (27%). Median distance to the OHCA was 560 m (IQR 332-860 m), and 1280 m (IQR 748-1776 m) via AED pick-up. The survey-answering rate was 82%. A smartphone application can be used to alert CPR-trained lay volunteers to OHCAs for CPR. Further improvements are needed to shorten the time to defibrillation before EMS arrival.

Exploring lay perceptions of the causes of crib-biting/windsucking behaviour in horses.

Litva, A; Robinson, C S; Archer, D C

2010-05-01

Crib-biting/windsucking behaviour has important consequences for equine health and welfare. Lay perceptions of health and illness are of interest to medical sociologists, providing important information to medical practitioners, but have infrequently been applied in veterinary research. To demonstrate how lay epidemiology can be applied within veterinary research by exploring the lay perceptions regarding the causes of crib-biting/windsucking behaviour in horses. Informants were recruited from professional and amateur horse owners who had or had not owned/cared for a horse that exhibited crib-biting/windsucking behaviour. In-depth interviews were used to examine perceptions about the development of this behaviour within each group until a 'saturation' of themes emerged. The main themes that emerged as causes of crib-biting/windsucking behaviour were 'boredom', 'stress' and 'habit/addiction'. In the group of owners/carers who did not have direct experience of this type of behaviour, 'copying' from other horses emerged as a strong theme and they stated that they would not wish to own a crib-biting/windsucking horse. In contrast, those who had direct experience of horses demonstrating this behaviour did not believe copying was a cause based on their own observations and would not be put off purchasing or caring for another horse displaying this behaviour. Perceptions about what causes crib-biting/windsucking was influenced by whether or not informants had personal experience of horses demonstrating this behaviour. The three main themes that emerged have some justification based on current research and highlight the need for further investigation into the underlying pathophysiology of crib-biting/windsucking behaviour. Qualitative approaches to health, disease and behaviour have an important role in the medical field and are applicable to veterinary research.

The naturalistic fallacy is modern.

Daston, Lorraine

2014-09-01

The naturalistic fallacy appears to be ubiquitous and irresistible. The avant-garde and the rearguard, the devout and the secular, the learned elite and the lay public all seem to want to enlist nature on their side, everywhere and always. Yet a closer look at the history of the term "naturalistic fallacy" and its associated arguments suggests that this way of understanding (and criticizing) appeals to nature's authority in human affairs is of relatively modern origin. To apply this category cross-historically masks considerable variability and naturalizes our own assumptions about the natural and the human.

I love you with all my brain: laying aside the intellectually dull sword of biological determinism

Background By organizing and activating our passions with both hormones and experiences, the heart and mind of sexual behavior, sexual motivation, and sexual preference is the brain, the organ of learning. Despite decades of progress, this incontrovertible truth is somehow lost in the far-too-often biologically deterministic interpretation of genetic, hormonal, and anatomical scientific research into the biological origins of sexual motivation. Simplistic and polarized arguments are used in the media by both sides of the seemingly endless debate over sexual orientation, equality, and human rights with such catch phrases as ‘born gay’ contrasted against attempts of “reparative therapy” or “pray the gay away”. Though long abandoned in practically every other area of psychology, this remnant of the nature-nurture controversy remains despite its generally acknowledged insufficiency in explaining any adult aspect of the human condition within the scientific community. Methods This theoretical review article identifies three factors: 1) good intentions with regard to the argument from immutability; 2) false dichotomies limiting intellectual progress by oversimplification of theory and thus hypothesis, and most dangerously, interpretation and; 3) Tradition: a historical separation of the disciplines of biology and psychology, which, to this day, interferes with the effective translation of well-conducted science into good public understanding and policy. Results Studies clearly demonstrate that progress toward sexual-orientation equality is being made, if slowly, despite the apparent irrelevance of the “born gay” argument from immutability. Evidence is further provided supporting the inadequacy of polarized, dichotic theories of sexual development, particularly those pitting “blank slate learning” against a fated, deterministic biological perspective. Results of this review suggest that an emerging interactionist perspective will promote both better scientific progress and better public understanding, hopefully contributing to progress toward nondiscriminatory public policy. Conclusion Accepting that the brain is a highly plastic, modularly dimorphic, developmentally biased organ of learning, one which is organized and activated by both hormones and experiences across the lifespan, is essential for doing “good science” well. Interactionist theories of psychosexual development provide an empirically sound, strong, yet modifiable foundation for testable hypotheses exploring biologically biased sexual learning.

Posthumous Reproduction (PHR) in Israel: Policy Rationales Versus Lay People's Concerns, a Preliminary Study.

PubMed

Hashiloni-Dolev, Yael

2015-12-01

Israeli policy concerning PHR has been decided upon in an expertocratic manner, leaving the voice of the public unheard. Based on 26 semi-structured in-depth interviews with 13 Jewish-Israeli young couples, this preliminary study provides the first empirical data regarding lay attitudes toward PHR in Israel. Findings suggest major dissimilarities between the policy and lay people's wishes and rationales. While policy is built on the "presumed wish" assumption, supposing all men living in a loving relationship wish to have their partner carry their child post-mortem, this was empirically unsupported. However, the findings suggest that many interviewees were willing to defer to their surviving spouse's wishes to have their post-mortem child, sometimes even against their own wish, indicating a support for presumed consent. Respecting the wishes of the dead, a dominant argument in the bioethical discussion in Israel and beyond, was mainly irrelevant to informants, whereas interviewees considered the future child's welfare, a concern overlooked by Israeli policy. Likewise, while posthumous grandparenthood is on the rise in Israel, it clearly contradicts the wishes of the majority of this study's informants. Nonetheless, existing policy is not expected to raise any opposition, due to the extreme liberalism of the participants and their support of reproductive autonomy.

Evolutionary contingency and SETI revisited

NASA Astrophysics Data System (ADS)

Cirkovic, Milan M.

2014-07-01

The well-known argument against the Search for ExtraTerrestrial Intelligence (SETI) due to George Gaylord Simpson is re-analyzed almost half a century later, in the light of our improved understanding of preconditions for the emergence of life and intelligence brought about by the ongoing "astrobiological revolution". Simpson's argument has been enormously influential, in particular in biological circles, and it arguably fueled the most serious opposition to SETI programmes and their funding. I argue that both proponents and opponents of Simpson's argument have occasionally mispresented its core content. Proponents often oversimplify it as just another consequence of biological contingency, thus leaving their position open to general arguments limiting the scope of contingency in evolution (such as the recent argument of Geerat Vermeij based on selection effects in the fossil record). They also tend to neglect that the argument has been presented as essentially atemporal, while referring to entities and processes that are likely to change over time; this has become even less justifiable as our astrobiological knowledge increased in recent years. Opponents have failed to see that the weaknesses in Simpson's position could be removed by restructuring of the argument; I suggest one way of such restructuring, envisioned long ago in the fictional context by Stanislaw Lem. While no firm consensus has emerged on the validity of Simpson's argument so far, I suggest that, contrary to the original motivation, today it is less an anti-SETI argument, and more an astrobiological research programme. In this research programme, SETI could be generalized into a platform for testing some of the deepest assumptions about evolutionary continuity and the relative role of contingency versus convergence on unprecedented spatial and temporal scales.

Professional responsibilities of biomedical scientists in public discourse

PubMed Central

Schuklenk, U

2004-01-01

This article describes how a small but vocal group of biomedical scientists propagates the views that either HIV is not the cause of AIDS, or that it does not exist at all. When these views were rejected by mainstream science, this group took its views and arguments into the public domain, actively campaigning via newspapers, radio, and television to make its views known to the lay public. I describe some of the harmful consequences of the group's activities, and ask two distinct ethical questions: what moral obligations do scientists who hold such minority views have with regard to a scientifically untrained lay audience, and what moral obligations do mainstream newspapers and government politicians have when it comes to such views. The latter question will be asked because the "dissidents" succeeded for a number of years in convincing the South African government of the soundness of their views. The consequences of their stance affected millions of HIV infected South Africans severely. PMID:14872076

Core values versus common sense: consequentialist views appear less rooted in morality.

PubMed

Kreps, Tamar A; Monin, Benoît

When a speaker presents an opinion, an important factor in audiences' reactions is whether the speaker seems to be basing his or her decision on ethical (as opposed to more pragmatic) concerns. We argue that, despite a consequentialist philosophical tradition that views utilitarian consequences as the basis for moral reasoning, lay perceivers think that speakers using arguments based on consequences do not construe the issue as a moral one. Five experiments show that, for both political views (including real State of the Union quotations) and organizational policies, consequentialist views are seen to express less moralization than deontological views, and even sometimes than views presented with no explicit justification. We also demonstrate that perceived moralization in turn affects speakers' perceived commitment to the issue and authenticity. These findings shed light on lay conceptions of morality and have practical implications for people considering how to express moral opinions publicly. © 2014 by the Society for Personality and Social Psychology, Inc.

Argumentation Key to Communicating Climate Change to the Public

NASA Astrophysics Data System (ADS)

Bleicher, R. E.; Lambert, J. L.

2012-12-01

Argumentation plays an important role in how we communicate climate change science to the public and is a key component integrated throughout the Next Generation Science Standards. A scientific argument can be described as a disagreement between explanations with data being used to justify each position. Argumentation is social process where two or more individuals construct and critique arguments (Kuhn & Udell, 2003; Nussbaum, 1997). Sampson, Grooms, and Walker's (2011) developed a framework for understanding the components of a scientific argument. The three components start with a claim (a conjecture, conclusion, explanation, or an answer to a research question). This claim must fit the evidence (observations that show trends over time, relationships between variables or difference between groups). The evidence must be justified with reasoning (explains how the evidence supports the explanation and whey it should count as support). In a scientific argument, or debate, the controversy focuses on how data were collected, what data can or should be included, and what inferences can be made based on a set of evidence. Toulmin's model (1969) also includes rebutting or presenting an alternative explanation supported by counter evidence and reasoning of why the alternative is not the appropriate explanation for the question of the problem. The process of scientific argumentation should involve the construction and critique of scientific arguments, one that involves the consideration of alternative hypotheses (Lawson, 2003). Scientific literacy depends as much on the ability to refute and recognize poor scientific arguments as much as it does on the ability to present an effective argument based on good scientific data (Osborne, 2010). Argument is, therefore, a core feature of science. When students learn to construct a sound scientific argument, they demonstrate critical thinking and a mastery of the science being taught. To present a convincing argument in support of climate change, students must have a sound foundation in the science underlying it. One place to lay this foundation is in the high school science classroom. For students to gain a good conceptual understanding of climate change science, teachers need a sound understanding of climate change and effective resources to teach it to students. Teacher professional development opportunities are required to provide this background as well as establish collaborative curriculum planning opportunities on the school site (Shulman, 2007). Various strategies for and challenges of implementing argumentation with preservice and practicing teachers will be discussed in this session, as well as ways that argumentation skills can help the broader public evaluate claims of climate skeptics. In the field of argumentation theory, Goodwin (2010) has designed a strategy for developing the ability to make effective scientific arguments. The goal is to establish trust even when there is strong disagreement. At the core, a student fully acknowledges the uncertainty involved in the complex science underlying climate change. This has the effect of establishing some degree of trust. In other words, teachers or students trying to explain climate change to others might be perceived as more trustworthy if they openly declare that there are degrees of uncertainty in different aspects of climate change science (American Meteorological Society, 2011).

Educational pelvic exams on anesthetized women: Why consent matters.

PubMed

Friesen, Phoebe

2018-06-01

It is argued here that the practice of medical students performing pelvic exams on women who are under anesthetic and have not consented is immoral and indefensible. This argument begins by laying out the ethical justification for the practice of informed consent, which can be found in autonomy and basic rights. Foregoing the process of consent within medicine can result in violations of both autonomy and basic rights, as well as trust, forming the basis of the wrong of unauthorized pelvic examinations. Several objections to this argument are considered, all of which stem from the idea that this practice constitutes an exception to the general requirement of informed consent. These objections suggest that nonconsensual pelvic examinations on women under anesthetic are ethically acceptable on utilitarian grounds, in that they offer benefits either to the patient or to society, or on the grounds of triviality, in that consent is already presumed, or the practice is insignificant. Each of these objections is rejected and the practice is deemed indefensible. © 2018 John Wiley & Sons Ltd.

Justice-based social assistance

Barrientos, Armando

2016-01-01

What are the main objectives of social protection institutions in developing countries? What should be their scope and reach? What is the source of their legitimacy? Finding appropriate answers to these questions is essential to understanding, and shaping, the emergence of welfare institutions in low- and middle-income countries. Most available answers rely on instrumental arguments. Few make reference to normative principles. This article draws on three concepts from Rawls – social justice as regulating cooperation, the social minimum, and the need for a freestanding political notion of social justice – to develop a coherent argument for grounding social assistance on social justice. In line with this argument, it identifies some parameters for a justice-based social assistance. This article then discusses, with examples, the tensions existing between a social justice-based social minimum and ‘real’ social assistance institutions emerging in developing countries.

Expectations in the field of the Internet and health: an analysis of claims about social networking sites in clinical literature

PubMed Central

Koteyko, Nelya; Hunt, Daniel; Gunter, Barrie

2015-01-01

This article adopts a critical sociological perspective to examine the expectations surrounding the uses of social networking sites (SNSs) articulated in the domain of clinical literature. This emerging body of articles and commentaries responds to the recent significant growth in SNS use, and constitutes a venue in which the meanings of SNSs and their relation to health are negotiated. Our analysis indicates how clinical writing configures the role of SNSs in health care through a range of metaphorical constructions that frame SNSs as a tool, a conduit for information and a traversable space. The use of such metaphors serves not only to describe the new affordances offered by SNSs but also posits distinct lay and professional practices, while reviving a range of celebratory claims about the Internet and health critiqued in sociological literature. These metaphorical descriptions characterise SNS content as essentially controllable by autonomous users while reiterating existing arguments that e-health is both inherently empowering and risky. Our analysis calls for a close attention to these understandings of SNSs as they have the potential to shape future online initiatives, most notably by anticipating successful professional interventions while marginalising the factors that influence users’ online and offline practices and contexts.

We describe some core principles that can facilitate the development of such a model and conclude that the resources in terms of time and effort that such an approach requires, should not be underestimated.

The law criminalizing attempted suicide in Ghana: the views of clinical psychologists, emergency ward nurses, and police officers.

2014-01-01

Attempted suicide is still considered a crime in Ghana. The purpose of this study was to investigate the attitudes toward this law held by health workers and police officers in Ghana so as to provide culture-sensitive arguments to aid in abolishing the law. Qualitative interviews were conducted with eight clinical psychologists, eight emergency ward nurses, and eight police officers. The majority of informants did not agree with the law criminalizing attempted suicide in Ghana, although five of the emergency ward nurses and two police officers did. Arguments for agreeing with the law were that people have no right to take life and that the law has a deterrent effect and thus it will help reduce the suicide rate. The main argument for not agreeing with the law was that suicidal behavior is a mental health issue. Those who argued in favor of the law did not seem to reflect much on the reasons for suicidal behavior. Education on how to understand suicidal behavior and suicidal people may aid the work toward decriminalizing attempted suicide in Ghana.

Access to essential medicines: a Hobbesian social contract approach.

PubMed

Ashcroft, Richard E

2005-05-01

Medicines that are vital for the saving and preserving of life in conditions of public health emergency or endemic serious disease are known as essential medicines. In many developing world settings such medicines may be unavailable, or unaffordably expensive for the majority of those in need of them. Furthermore, for many serious diseases (such as HIV/AIDS and tuberculosis) these essential medicines are protected by patents that permit the patent-holder to operate a monopoly on their manufacture and supply, and to price these medicines well above marginal cost. Recent international legal doctrine has placed great stress on the need to globalise intellectual property rights protections, and on the rights of intellectual property rights holders to have their property rights enforced. Although international intellectual property rights law does permit compulsory licensing of protected inventions in the interests of public health, the use of this right by sovereign states has proved highly controversial. In this paper I give an argument in support of states' sovereign right to expropriate private intellectual property in conditions of public health emergency. This argument turns on a social contract argument for the legitimacy of states. The argument shows, further, that under some circumstances states are not merely permitted compulsory to license inventions, but are actually obliged to do so, on pain of failure of their legitimacy as sovereign states. The argument draws freely on a loose interpretation of Thomas Hobbes's arguments in his Leviathan, and on an analogy between his state of War and the situation of public health disasters.

Emergency Preparedness and Disaster Response: There's An App for That.

Bachmann, Daniel J; Jamison, Nathan K; Martin, Andrew; Delgado, Jose; Kman, Nicholas E

2015-10-01

Smartphone applications (or apps) are becoming increasingly popular with emergency responders and health care providers, as well as the public as a whole. There are thousands of medical apps available for Smartphones and tablet computers, with more added each day. These include apps to view textbooks, guidelines, medication databases, medical calculators, and radiology images. Hypothesis/Problem With an ever expanding catalog of apps that relate to disaster medicine, it is hard for both the lay public and responders to know where to turn for effective Smartphone apps. A systematic review of these apps was conducted. A search of the Apple iTunes store (Version 12; Apple Inc.; Cupertino, California USA) was performed using the following terms obtained from the PubMed Medical Subject Headings Database: Emergency Preparedness, Emergency Responders, Disaster, Disaster Planning, Disaster Medicine, Bioterrorism, Chemical Terrorism, Hazardous Materials (HazMat), and the Federal Emergency Management Agency (FEMA). After excluding any unrelated apps, a working list of apps was formed and categorized based on topics. Apps were grouped based on applicability to responders, the lay public, or regional preparedness, and were then ranked based on iTunes user reviews, value, relevance to audience, and user interface. This search revealed 683 applications and was narrowed to 219 based on relevance to the field. After grouping the apps as described above, and subsequently ranking them, the highest quality apps were determined from each group. The Community Emergency Response Teams and FEMA had the best apps for National Disaster Medical System responders. The Centers for Disease Control and Prevention (CDC) had high-quality apps for emergency responders in a variety of fields. The National Library of Medicine's Wireless Information System for Emergency Responders (WISER) app was an excellent app for HazMat responders. The American Red Cross had the most useful apps for natural disasters. Numerous valuable apps for public use, including alert apps, educational apps, and a well-made regional app, were also identified. Smartphone applications are fast becoming essential to emergency responders and the lay public. Many high-quality apps existing in various price ranges and serving different populations were identified. This field is changing rapidly and it deserves continued analysis as more apps are developed.

Weaver, W D; Sutherland, K; Wirkus, M J; Bachman, R

1989-02-01

During the 1986 World's Exposition held in Vancouver, British Columbia, the types and frequencies of emergency medical problems were assessed. The average number of patients seeking care was 3.93 +/- 0.95 per 1,000 visitors (daily range, 1.94 to 6.8). Patient loads were linearly related to gate attendance, but the correlation was imperfect (P less than .001, r = .63). Only 4.4% of patients evaluated on site by nurses and paramedics were referred for additional testing and treatment: of these patients, 30% had suspected serious musculoskeletal injury, 16% had abdominal pain, and 25% had complaints of chest pain, dizziness, or loss of consciousness. Lay employees (security personnel) were trained to use automatic external defibrillators. There were six cardiac arrests (0.3 per million visitors). Two patients collapsed with ventricular fibrillation, were defibrillated by lay personnel, quickly regained consciousness, and survived. The other arrests were associated with asystole or electromechanical dissociation; no shocks were inappropriately given, and all four died. We conclude that four of every 1,000 persons at this assembly sought emergency medical care, that 95% of the problems seen were minor with few requiring physician skills, and that the automatic external defibrillator was suited for this setting and could be used by lay responders to provide early definitive treatment.

Social representations of climate change in Swedish lay focus groups: local or distant, gradual or catastrophic?

Wibeck, Victoria

2014-02-01

This paper explores social representations of climate change, investigating how climate change is discussed by Swedish laypeople interacting in focus group interviews. The analysis focuses on prototypical examples and metaphors, which were key devices for objectifying climate change representations. The paper analyzes how the interaction of focus group participants with other speakers, ideas, arguments, and broader social representations shaped their representations of climate change. Climate change was understood as a global but distant issue with severe consequences. There was a dynamic tension between representations of climate change as a gradual vs. unpredictable process. Implications for climate change communication are discussed.

In this case study, an Australian science teacher participated in a one-on-one professional learning session on argumentation before explicitly teaching argumentation skills to two year 10 classes studying genetics. Over two lessons, the teacher used whole class discussion and writing frames of two socioscientific issues to teach students about argumentation. An analysis of classroom observation field notes, audiotaped lesson transcripts, writing frames and student interviews indicate that four factors promoted student argumentation. The factors are: the role of the teacher in facilitating whole class discussion; the use of writing frames; the context of the socioscientific issue; and the role of the students. It is recommended that professional learning to promote student argumentation may need to be tailored to individual teachers and that extensive classroom based research is required to determine the impact of classroom factors on students’ argumentation.

Ever since the emergence of SARS, when we were reminded that the nature of health care practitioners' duty to care is greatly contested, it has remained a polarizing issue. Discussions on the nature and limits of health care practitioners' duty to care during disasters and public health emergencies abounds the literature, ripe with arguments seeking to ground its foundations. However, to date there has been little public engagement on this issue. This study involved three Townhall meetings held between February 2008 and May 2010 in three urban settings in Canada in order to probe lay citizens' views about ethical issues related to pandemic influenza, including issues surrounding the duty to care. Participants included Canadian residents aged 18 and over who were fluent in English. Data were collected through day-long facilitated group discussions using case scenarios and focus group guides. Participant's views were organized according to several themes, including the following main themes (and respective sub-themes): 1. Legitimate limits; a) competing obligations; and b) appeal to personal choice; and 2. Legitimate expectations; a) reciprocity; and b) enforcement and planning. Our findings show that participants moved away from categorical notions of the duty to care towards more equivocal and often normative views throughout deliberations. Our analysis contributes a better understanding of the constitutive nature of the duty to care, defined in part by taking account of public views. This broadened understanding can further inform the articulation of acceptable norms of duty to care and policy development efforts. What is more, it illustrates the urgent need for policy-makers and regulators to get clarity on obligations, responsibilities, and accountability in the execution of HCPs' duty to care during times of universal vulnerability.

Exploring How Lay Rescuers Overcome Barriers to Provide Cardiopulmonary Resuscitation: A Qualitative Study.

Mathiesen, Wenche Torunn; Bjørshol, Conrad Arnfinn; Høyland, Sindre; Braut, Geir Sverre; Søreide, Eldar

2017-02-01

Survival rates after out-of-hospital cardiac arrest (OHCA) vary considerably among regions. The chance of survival is increased significantly by lay rescuer cardiopulmonary resuscitation (CPR) before Emergency Medical Services (EMS) arrival. It is well known that for bystanders, reasons for not providing CPR when witnessing an OHCA incident may be fear and the feeling of being exposed to risk. The aim of this study was to gain a better understanding of why barriers to providing CPR are overcome. Using a semi-structured interview guide, 10 lay rescuers were interviewed after participating in eight OHCA incidents. Qualitative content analysis was used. The lay rescuers were questioned about their CPR-knowledge, expectations, and reactions to the EMS and from others involved in the OHCA incident. They also were questioned about attitudes towards providing CPR in an OHCA incident in different contexts. The lay rescuers reported that they were prepared to provide CPR to anybody, anywhere. Comprehending the severity in the OHCA incident, both trained and untrained lay rescuers provided CPR. They considered CPR provision to be the expected behavior of any community citizen and the EMS to act professionally and urgently. However, when asked to imagine an OHCA in an unclear setting, they revealed hesitation about providing CPR because of risk to their own safety. Mutual trust between community citizens and towards social institutions may be reasons for overcoming barriers in providing CPR by lay rescuers. A normative obligation to act, regardless of CPR training and, importantly, without facing any adverse legal reactions, also seems to be an important factor behind CPR provision.

COHORT CHANGES IN THE SOCIAL DISTRIBUTION OF TOLERANT SEXUAL ATTITUDES

PubMed Central

Pampel, Fred C.

2017-01-01

Though many studies have described societal-wide changes in tolerance for sexual behaviors outside marriage, few have examined how the social distribution of tolerant attitudes has changed. A diffusion-of-innovations approach predicts nonlinear change in the distribution: high SES groups adopt the attitudes first, which produces a positive relationship, but diffusion to other SES groups subsequently weakens the association with SES. I test this argument using the General Social Survey from 1973 to 2014 to compare the SES determinants of attitudes toward premarital sex, extramarital sex, same-gender sex, and teenage sex across 86 cohorts born from around 1900 to 1985. Multilevel age, period, and cohort models support diffusion arguments concerning tolerance of premarital sex by demonstrating that the effects of indicators of SES first strengthen and then weaken across cohorts. Little support emerges for diffusion arguments concerning tolerance of extramarital sex and teenage sex, and preliminary but suggestive support emerges concerning tolerance of same-gender sex.

2003-11-01

Automated external defibrillators (AEDs) have become increasingly available outside of the Emergency Medical Systems (EMS) community to treat sudden cardiac arrest (SCA). We sought to study the use of AEDs in the home, businesses and other public settings by minimally trained first responders. The frequency of AED use, type of training offered to first responders, and outcomes of AED use were investigated. In addition, minimally trained responders were asked if they had encountered any safety problems associated with the AED. We conducted a telephone survey of businesses and public facilities (2683) and homes (145) owning at least one AED for at least 12 months. Use was defined as an AED taken to a medical emergency thought to be a SCA, regardless of whether the AED was applied to the patient or identified a shockable rhythm. Of owners that participated in the survey, 13% (209/1581) of businesses and 5% (4/73) of homes had responded with the AED to a suspected cardiac arrest. Ninety-five percent of the businesses/public facilities offered training that specifically covered AED use. The rate of use for the AEDs was highest in residential buildings, public places, malls and recreational facilities with an overall usage rate of 11.6% per year. In-depth interviews were conducted with lay responders who had used the AED in a suspected cardiac arrest. In the four cases where the AED was used solely by a lay responder, all four patients survived to hospital admission and two were known to be discharged from the hospital. There were no reports of injury or harm. This survey demonstrates that AEDs purchased by businesses and homes were frequently taken to suspected cardiac arrests. Lay responders were able to successfully use the AEDs in emergency situations. Further, there were no reports of harm or injury to the operators, bystanders or patients from lay responder use of the AEDs.

Expectations in the field of the internet and health: an analysis of claims about social networking sites in clinical literature.

Koteyko, Nelya; Hunt, Daniel; Gunter, Barrie

2015-03-01

This article adopts a critical sociological perspective to examine the expectations surrounding the uses of social networking sites (SNSs) articulated in the domain of clinical literature. This emerging body of articles and commentaries responds to the recent significant growth in SNS use, and constitutes a venue in which the meanings of SNSs and their relation to health are negotiated. Our analysis indicates how clinical writing configures the role of SNSs in health care through a range of metaphorical constructions that frame SNSs as a tool, a conduit for information and a traversable space. The use of such metaphors serves not only to describe the new affordances offered by SNSs but also posits distinct lay and professional practices, while reviving a range of celebratory claims about the Internet and health critiqued in sociological literature. These metaphorical descriptions characterise SNS content as essentially controllable by autonomous users while reiterating existing arguments that e-health is both inherently empowering and risky. Our analysis calls for a close attention to these understandings of SNSs as they have the potential to shape future online initiatives, most notably by anticipating successful professional interventions while marginalising the factors that influence users' online and offline practices and contexts. © 2015 The Authors.

COHORT CHANGE, DIFFUSION, AND SUPPORT FOR ENVIRONMENTAL SPENDING IN THE UNITED STATES.

PubMed

Pampel, Fred C; Hunter, Lori M

2012-09-01

The long-standing and sometimes heated debates over the direction and size of the effect of socioeconomic status (SES) on environmental concern contrast post-materialist and affluence arguments, suggesting a positive relationship in high-income nations, with counter arguments for a negative or near zero relationship. A diffusion-of-innovations approach adapts parts of both arguments by predicting that high SES groups first adopt pro-environmental views, which produces a positive relationship. Like other innovations, however, environmentalism diffuses over time to other SES groups, which subsequently weakens the association. We test this argument using the General Social Survey from 1973 to 2008 to compare support for environmental spending across 83 cohorts born from around 1900 to 1982. In developing attitudes before, during, and after the emergence of environmentalism, varying cohorts provide the contrast needed to identify long-term changes in environmental concern. Multilevel age, period, and cohort models support diffusion arguments by demonstrating the effects, across cohorts, of three common indicators of SES - education, income and occupational prestige - first strengthen and then weaken. This finding suggests that diffusion of environmental concern first produces positive relationships consistent with postmaterialism arguments and later produces null or negative relationships consistent with global environmentalism arguments.

This study was conducted to assess the prevention of egg laying and the inhibition of the emergence of the cat flea (Ctenocephalides felis) resulting from the application of a combination of fipronil and permethrin (Frontline Tri-Act®/Frontect®, Merial) on dogs. Sixteen healthy dogs were included after pre-treatment live flea counts and randomly allocated to two groups. Eight dogs served as untreated controls and 8 dogs were treated on Day 0 and Day 30 with topical application of fipronil/permethrin at the minimum dose of 6.76 mg/kg fipronil and 50.48 mg/kg permethrin. On days −2, 7, 21, 28, 42 and 56, each dog was infested with 100 fleas. Flea eggs were collected from each dog in individual trays from 12 to 36 h after treatment or each flea re-infestation. All fleas were removed by combing and counted 36 h after treatment or infestations. The collected eggs were counted and incubated for 28 days for larval development and adult emergence assessment. The curative efficacy of Frontline Tri-Act®/Frontect® against adult fleas 36 h after treatment was 95.3% and the efficacy remained 100% after subsequent flea infestations for 8 weeks. Compared to the control group, the treatment reduced egg laying by 84.5% within 36 h after first treatment and was 99.9%, 100%, 100%, 100%, 100% on collection days 7, 21, 29, 43 and 57, respectively. Frontline Tri-Act®/Frontect® reduced by 28.7% the emergence of new adult fleas from eggs laid during the 48 h of pre-treatment infestation. The inhibition of adult emergence from incubated flea eggs could not be assessed after flea re-infestation in the treated group as no eggs were collected. PMID:27991415

Turning point or tipping point: new FDA draft guidances and the future of DTC advertising.

Pitts, Peter J

2004-01-01

According to Food and Drug Administration (FDA) research, direct-to-consumer (DTC) drug ads are not as empowering as they were even three years ago. How will the FDA's new draft guidances reverse this trend and affect the future of DTC advertising? Will they be a turning point, resulting in pharmaceutical companies' embracing an educational public health imperative, or a tipping point with politicians and the public zeroing in on aggressively targeted DTC ads as the postimportation pharmaceutical bête noire? The FDA believes that its new guidances strengthen the strategic argument that a better-informed consumer lays the groundwork for a better potential customer.

Philosophers assess randomized clinical trials: the need for dialogue.

PubMed

Miké, V

1989-09-01

In recent years a growing number of professional philosophers have joined in the controversy over ethical aspects of randomized clinical trials (RCTs). Morally questionable in their utilitarian approach, RCTs are claimed by some to be in direct violation of the second form of Kant's Categorical Imperative. But the arguments used in these critiques at times derive from a lack of insight into basic statistical procedures and the realities of the biomedical research process. Presented to physicians and other nonspecialists, including the lay public, such distortions can be harmful. Given the great complexity of statistical methodology and the anomalous nature of concepts of evidence, more sustained input into the interdisciplinary dialogue is needed from the statistical profession.

Objective Cardiopulmonary resuscitation (CPR) provided by community citizens is of paramount importance for out-of-hospital cardiac arrest (OHCA) victims' survival. Fortunately, CPR rates by community citizens seem to be rising. However, the experience of providing CPR is rarely investigated. The aim of this study was to explore reactions and coping strategies in lay rescuers who have provided CPR to OHCA victims. Methods, participants This is a qualitative study of 20 lay rescuers who have provided CPR to 18 OHCA victims. We used a semistructured interview guide focusing on their experiences after providing CPR. Setting The study was conducted in the Stavanger region of Norway, an area with very high bystander CPR rates. Results Three themes emerged from the interview analysis: concern, uncertainty and coping strategies. Providing CPR had been emotionally challenging for all lay rescuers and, for some, had consequences in terms of family and work life. Several lay rescuers experienced persistent mental recurrences of the OHCA incident and had concerns about the outcome for the cardiac arrest victim. Unknown or fatal outcomes often caused feelings of guilt and were particularly difficult to handle. Several reported the need to be acknowledged for their CPR attempts. Health-educated lay rescuers seemed to be less affected than others. A common coping strategy was confiding in close relations, preferably the health educated. However, some required professional help to cope with the OHCA incident. Conclusions Lay rescuers experience emotional and social challenges, and some struggle to cope in life after providing CPR in OHCA incidents. Experiencing a positive patient outcome and being a health-educated lay rescuer seem to mitigate concerns. Common coping strategies are attempts to reduce uncertainty towards patient outcome and own CPR quality. Further studies are needed to determine whether an organised professional follow-up can mitigate the concerns and uncertainty of lay rescuers. PMID:27225648

The Expert and the Lay Public: Reflections on Influenza A (H1N1) and the Risk Society

PubMed Central

Williams-Jones, Bryn

2012-01-01

Trust between the lay public and scientific experts is a key element to ensuring the efficient implementation of emergency public health measures. In modern risk societies, the management and elimination of risk have become preeminent drivers of public policy. In this context, the protection of public trust is a complex task. Those actors involved in public health decision-making and implementation (e.g., mass vaccination for influenza A virus) are confronted with growing pressures and responsibility to act. However, they also need to accept the limits of their own expertise and recognize the ability of lay publics to understand and be responsible for public health. Such a shared responsibility for risk management, if grounded in participative public debates, can arguably strengthen public trust in public health authorities and interventions. PMID:22397338

2013-01-16

Women who have a breech presentation at term have to decide whether to attempt external cephalic version (ECV) and how they want to give birth if the baby remains breech, either by planned caesarean section (CS) or vaginal breech birth. The aim of this study was to explore the attitudes of women with a breech presentation and health professionals who manage breech presentation to ECV. We carried out semi-structured interviews with pregnant women with a breech presentation (n=11) and health professionals who manage breech presentation (n=11) recruited from two hospitals in North East England. We used purposive sampling to include women who chose ECV and women who chose planned CS. We analysed data using thematic analysis, comparing between individuals and seeking out disconfirming cases. Four main themes emerged from the data collected during interviews with pregnant women with a breech presentation: ECV as a means of enabling natural birth; concerns about ECV; lay and professional accounts of ECV; and breech presentation as a means of choosing planned CS. Some women's attitudes to ECV were affected by their preferences for how to give birth. Other women chose CS because ECV was not acceptable to them. Two main themes emerged from the interview data about health professionals' attitudes towards ECV: directive counselling and attitudes towards lay beliefs about ECV and breech presentation. Women had a range of attitudes to ECV informed by their preferences for how to give birth; the acceptability of ECV to them; and lay accounts of ECV, which were frequently negative. Most professionals described having a preference for ECV and reported directively counselling women to choose it. Some professionals were dismissive of lay beliefs about ECV. Some key challenges for shared decision making about breech presentation were identified: health professionals counselling women directively about ECV and the differences between evidence-based information about ECV and lay beliefs. To address these challenges a number of approaches will be required.

The objective of this study was to determine the attitude of patients, healthcare professionals, and noninjured lay persons towards adding a video with discharge instructions to patient care for patients with mild traumatic brain injury (MTBI). A survey was conducted at the emergency department (ED). Participants consisted of MTBI patients (n = 50), healthcare professionals (n = 50), and noninjured lay persons (n = 50). The participants viewed a video with discharge instructions on MTBI and filled out a questionnaire that measured their attitude towards the use of a video as part of discharge instructions. Nearly all healthcare professionals (94%) and 70% of the noninjured lay persons considered the video to be a valuable addition to oral discharge instructions. For 84% of patients, verbal information from the doctor is of importance. And, 50% of patients would like to receive additional video discharge instructions. The majority of noninjured lay persons and healthcare professionals and half of the MTBI patients consider a video with discharge instructions to be a valuable addition to patient care. Video discharge instructions are a relative low-cost measure that could enhance patient care at the ED, provided that this does not compromise the personal contact between patient and healthcare professional.

Effective field theory of emergent symmetry breaking in deformed atomic nuclei

Spontaneous symmetry breaking in non-relativistic quantum systems has previously been addressed in the framework of effective field theory. Low-lying excitations are constructed from Nambu–Goldstone modes using symmetry arguments only. In this study, we extend that approach to finite systems. The approach is very general. To be specific, however, we consider atomic nuclei with intrinsically deformed ground states. The emergent symmetry breaking in such systems requires the introduction of additional degrees of freedom on top of the Nambu–Goldstone modes. Symmetry arguments suffice to construct the low-lying states of the system. Lastly, in deformed nuclei these are vibrational modes each of whichmore » serves as band head of a rotational band.« less

The emergence of complexity in prosody and syntax

2011-01-01

The relation between prosody and syntax is investigated here by tracing the emergence of each in a new language, Al-Sayyid Bedouin Sign Language. We analyze the structure of narratives of four signers of this language: two older second generation signers, and two about 15 years younger. We find that younger signers produce prosodic cues to dependency between semantically related constituents, e.g., the two clauses of conditionals, revealing a type and degree of complexity in their language that is not frequent in that of the older pair. In these younger signers, several rhythmic and (facial) intonational cues are aligned at constituent boundaries, indicating the emergence of a grammatical system. There are no overt syntactic markers (such as complementizers) to relate clauses; prosody is the only clue. But this prosodic complexity is matched by syntactic complexity inside propositions in the younger signers, who are more likely to use pronouns as abstract grammatical markers of arguments, and to combine predicates with their arguments within in a constituent. As the prosodic means emerge for identifying constituent types and signaling dependency relations between them, the constituents themselves become increasingly complex. Finally, our study shows that the emergence of grammatical complexity is gradual. PMID:23087486

2006-03-07

Cardiovascular disease is a leading cause of death for adults > or =40 years of age. The American Heart Association (AHA) estimates that sudden cardiac arrest is responsible for about 250,000 out-of-hospital deaths annually in the United States. Since the early 1990s, the AHA has called for innovative approaches to reduce time to cardiopulmonary resuscitation (CPR) and defibrillation and improve survival from sudden cardiac arrest. In the mid-1990s, the AHA launched a public health initiative to promote early CPR and early use of automated external defibrillators (AEDs) by trained lay responders in community (lay rescuer) AED programs. Between 1995 and 2000, all 50 states passed laws and regulations concerning lay rescuer AED programs. In addition, the Cardiac Arrest Survival Act (CASA, Public Law 106-505) was passed and signed into federal law in 2000. The variations in state and federal legislation and regulations have complicated efforts to promote lay rescuer AED programs and in some cases have created impediments to such programs. Since 2000, most states have reexamined lay rescuer AED statutes, and many have passed legislation to remove impediments and encourage the development of lay rescuer AED programs. The purpose of this statement is to help policymakers develop new legislation or revise existing legislation to remove barriers to effective community lay rescuer AED programs. Important areas that should be considered in state legislation and regulations are highlighted, and sample legislation sections are included. Potential sources of controversy and the rationale for proposed legislative components are noted. This statement will not address legislation to support home AED programs. Such recommendations may be made after the conclusion of a large study of home AED use.

This study examined the meaning of sickle cell trait and sickle cell trait screening from the lay perspective of African Americans. African Americans (N = 300), ages 18-35 and unaware of their sickle cell trait status, completed two open-ended questions from a larger survey. One question asked for their understanding of sickle cell trait; the other asked for their understanding of sickle cell trait screening. Content analysis occurred in two phases: (1) In vivo and holistic coding; and (2) focused coding. Four categories emerged illustrating lay conceptions of sickle cell trait; (1) Perceived as an illness; (2) Perceived recognition of the inheritance pattern of sickle cell trait; (3) Perceived lack of knowledge of sickle cell trait; and (4) Perceived importance of sickle cell trait. Five categories emerged illustrating lay conceptions for sickle cell trait screening: (1) Perceived recognition that screening means getting tested for sickle cell trait; (2) Perceived lack of knowledge of sickle cell trait screening; (3) Perceived health benefit of sickle cell trait screening; (4) Perceived importance of sickle cell trait screening; and (5) Perceived barriers to sickle cell trait screening. Sickle cell trait and sickle cell trait screening are concepts that are both regarded as important among this high-risk population. However, there is still misunderstanding concerning the hereditary nature and reproductive implications of sickle cell trait. Interventions seeking to improve communication on the need for sickle cell trait screening should begin by identifying what the population at large understands, knows and/or believes to improve their ability to make informed health decisions.

Further studies are needed to determine whether an organised professional follow-up can mitigate the concerns and uncertainty of lay rescuers. Published by the BMJ Publishing Group Limited.

Emergence, Learning Difficulties, and Misconceptions in Chemistry Undergraduate Students' Conceptualizations of Acid Strength

NASA Astrophysics Data System (ADS)

Tümay, Halil

2016-03-01

Philosophical debates about chemistry have clarified that the issue of emergence plays a critical role in the epistemology and ontology of chemistry. In this article, it is argued that the issue of emergence has also significant implications for understanding learning difficulties and finding ways of addressing them in chemistry. Particularly, it is argued that many misconceptions in chemistry may derive from students' failure to consider emergence in a systemic manner by taking into account all relevant factors in conjunction. Based on this argument, undergraduate students' conceptions of acids, and acid strength (an emergent chemical property) were investigated and it was examined whether or not they conceptualized acid strength as an emergent chemical property. The participants were 41 third- and fourth-year undergraduate students. A concept test and semi-structured interviews were used to probe students' conceptualizations and reasoning about acid strength. Findings of the study revealed that the majority of the undergraduate students did not conceptualize acid strength as an emergent property that arises from interactions among multiple factors. They generally focused on a single factor to predict and explain acid strength, and their faulty responses stemmed from their failure to recognize and consider all factors that affect acid strength. Based on these findings and insights from philosophy of chemistry, promoting system thinking and epistemologically sound argumentative discourses among students is suggested for meaningful chemical education.

Lay navigators in the Patient Care Connect Program support patients with cancer from diagnosis through survivorship to end of life. They empower patients to engage in their health care and navigate them through the increasingly complex health care system. Navigation programs can improve access to care, enhance coordination of care, and overcome barriers to timely, high-quality health care. However, few data exist regarding the financial implications of implementing a lay navigation program. To examine the influence of lay navigation on health care spending and resource use among geriatric patients with cancer within The University of Alabama at Birmingham Health System Cancer Community Network. This observational study from January 1, 2012, through December 31, 2015, used propensity score-matched regression analysis to compare quarterly changes in the mean total Medicare costs and resource use between navigated patients and nonnavigated, matched comparison patients. The setting was The University of Alabama at Birmingham Health System Cancer Community Network, which includes 2 academic and 10 community cancer centers across Alabama, Georgia, Florida, Mississippi, and Tennessee. Participants were Medicare beneficiaries with cancer who received care at participating institutions from 2012 through 2015. The primary exposure was contact with a patient navigator. Navigated patients were matched to nonnavigated patients on age, race, sex, cancer acuity (high vs low), comorbidity score, and preenrollment characteristics (costs, emergency department visits, hospitalizations, intensive care unit admissions, and chemotherapy in the preenrollment quarter). Total costs to Medicare, components of cost, and resource use (emergency department visits, hospitalizations, and intensive care unit admissions). In total, 12 428 patients (mean (SD) age at cancer diagnosis, 75 (7) years; 52.0% female) were propensity score matched, including 6214 patients in the navigated group and 6214 patients in the matched nonnavigated comparison group. Compared with the matched comparison group, the mean total costs declined by $781.29 more per quarter per navigated patient (β = -781.29, SE = 45.77, P < .001), for an estimated $19 million decline per year across the network. Inpatient and outpatient costs had the largest between-group quarterly declines, at $294 and $275, respectively, per patient. Emergency department visits, hospitalizations, and intensive care unit admissions decreased by 6.0%, 7.9%, and 10.6%, respectively, per quarter in navigated patients compared with matched comparison patients (P < .001). Costs to Medicare and health care use from 2012 through 2015 declined significantly for navigated patients compared with matched comparison patients. Lay navigation programs should be expanded as health systems transition to value-based health care.

Diversity and uniformity in genetic responsibility: moral attitudes of patients, relatives and lay people in Germany and Israel.

The professional and institutional responsibility for handling genetic knowledge is well discussed; less attention has been paid to how lay people and particularly people who are affected by genetic diseases perceive and frame such responsibilities. In this exploratory study we qualitatively examine the attitudes of lay people, patients and relatives of patients in Germany and Israel towards genetic testing. These attitudes are further examined in the national context of Germany and Israel, which represent opposite regulatory approaches and bioethical debates concerning genetic testing. Three major themes of responsibility emerged from the inter-group and cross-cultural comparison: self-responsibility, responsibility for kin, and responsibility of society towards its members. National contrast was apparent in the moral reasoning of lay respondents concerning, for example, the right not to know versus the duty to know (self-responsibility) and the moral conflict concerning informing kin versus the moral duty to inform (responsibility for kin). Attitudes of respondents affected by genetic diseases were, however, rather similar in both countries. We conclude by discussing how moral discourses of responsibility are embedded within cultural (national, religious) as well as phenomenological (being affected) narratives, and the role of public engagement in bioethical discourse.

Online patient education and risk assessment: project OPERA from Cancerbackup. Putting inherited breast cancer risk information into context using argumentation theory.

Many people are concerned about their family history of breast cancer, and are anxious about the possibility of developing breast cancer themselves. The majority of these people are likely not to be at significantly increased risk of developing inherited breast cancer. All women are at risk of developing sporadic breast cancer, and this risk increases with age. This project aims to aid people's understanding of these issues using an interactive online computer programme. The UK National Institute of Health and Clinical Excellence has published guidance for the National Health Service on the management of familial breast cancer. That guidance lays down clear criteria for categorising risk level and the appropriate management options. We have developed a user-friendly computer programme named OPERA (online patient education and risk assessment) which captures the individuality of the user's situation in a comprehensive way, and then produces personalised information packages, building on the theoretical framework of argumentation developed by Toulmin [Toulmin S. The uses of argument. Cambridge, MA: Cambridge University Press; 1958]. We will test this programme in a series of pilot studies commencing in 2007. This paper describes the progress of this project to date and focuses on the design of the programme. It is possible to construct a user friendly programme which delivers a personalised information package to individuals who are concerned about their risk of developing breast cancer. This user friendly programme needs to be tested within a series of carefully thought out pilot studies before it is ready for general release and use by the public.

Cardiopulmonary resuscitation in real life: the most frequent fears of lay rescuers.

Savastano, Simone; Vanni, Vincenzo

2011-05-01

Surviving cardiac arrest depends on early cardiopulmonary resuscitation (CPR). Only one third of cardiac arrest victims receive prompt CPR in spite of well-attended Basic Life Support (BLS) courses. Our study aimed to investigate that how many lay rescuers, capable of performing CPR, would do so, and to analyse their impeding fears. After each BLS course for lay rescuers (American Heart Association (AHA) CPR for family and friends), an anonymous questionnaire was distributed asking participants whether they would perform CPR on an adult or on a child in a real case of cardiac arrest. In the case of a negative response, we questioned them why. A total of 1000 questionnaires were analysed. The sample group was predominantly made up of males (77.7%), Italians (82.2%), individuals aged between 26 and 35 years (41.2%) and individuals possessing a high-school diploma (61.8%). The percentages that would perform CPR on an unknown adult or child were different (86.2% vs. 73.9% p = 0.005). The prevalent fears were regarding infection, being incapable, legal implications and causing damage and fear in general. The first three differ significantly in adult and paediatric cases. Subdividing the population according to sex, age and education did not demonstrate significant differences regarding willingness to perform adult or paediatric CPR. This descriptive study demonstrates that the percentage that would really perform CPR is too low, particularly in the case of a child. Part of the course should be dedicated to discussing these arguments to ensure that all those capable of performing good CPR would immediately do so. Copyright © 2010 Elsevier Ireland Ltd.

A qualitative interview study exploring pregnant women’s and health professionals’ attitudes to external cephalic version

PubMed Central

2013-01-01

Background Women who have a breech presentation at term have to decide whether to attempt external cephalic version (ECV) and how they want to give birth if the baby remains breech, either by planned caesarean section (CS) or vaginal breech birth. The aim of this study was to explore the attitudes of women with a breech presentation and health professionals who manage breech presentation to ECV. Methods We carried out semi-structured interviews with pregnant women with a breech presentation (n=11) and health professionals who manage breech presentation (n=11) recruited from two hospitals in North East England. We used purposive sampling to include women who chose ECV and women who chose planned CS. We analysed data using thematic analysis, comparing between individuals and seeking out disconfirming cases. Results Four main themes emerged from the data collected during interviews with pregnant women with a breech presentation: ECV as a means of enabling natural birth; concerns about ECV; lay and professional accounts of ECV; and breech presentation as a means of choosing planned CS. Some women’s attitudes to ECV were affected by their preferences for how to give birth. Other women chose CS because ECV was not acceptable to them. Two main themes emerged from the interview data about health professionals’ attitudes towards ECV: directive counselling and attitudes towards lay beliefs about ECV and breech presentation. Conclusions Women had a range of attitudes to ECV informed by their preferences for how to give birth; the acceptability of ECV to them; and lay accounts of ECV, which were frequently negative. Most professionals described having a preference for ECV and reported directively counselling women to choose it. Some professionals were dismissive of lay beliefs about ECV. Some key challenges for shared decision making about breech presentation were identified: health professionals counselling women directively about ECV and the differences between evidence-based information about ECV and lay beliefs. To address these challenges a number of approaches will be required. PMID:23324533

Playing God in Frankenstein's Footsteps: Synthetic Biology and the Meaning of Life.

PubMed

van den Belt, Henk

2009-12-01

The emergent new science of synthetic biology is challenging entrenched distinctions between, amongst others, life and non-life, the natural and the artificial, the evolved and the designed, and even the material and the informational. Whenever such culturally sanctioned boundaries are breached, researchers are inevitably accused of playing God or treading in Frankenstein's footsteps. Bioethicists, theologians and editors of scientific journals feel obliged to provide an authoritative answer to the ambiguous question of the 'meaning' of life, both as a scientific definition and as an explication with wider existential connotations. This article analyses the arguments mooted in the emerging societal debates on synthetic biology and the way its practitioners respond to criticism, mostly by assuming a defiant posture or professing humility. It explores the relationship between the 'playing God' theme and the Frankenstein motif and examines the doctrinal status of the 'playing God' argument. One particularly interesting finding is that liberal theologians generally deny the religious character of the 'playing God' argument-a response which fits in with the curious fact that this argument is used mainly by secular organizations. Synthetic biology, it is therefore maintained, does not offend so much the God of the Bible as a deified Nature. While syntheses of artificial life forms cause some vague uneasiness that life may lose its special meaning, most concerns turn out to be narrowly anthropocentric. As long as synthetic biology creates only new microbial life and does not directly affect human life, it will in all likelihood be considered acceptable.

Translanguaging in a middle school science classroom: Constructing scientific arguments in English and Spanish

NASA Astrophysics Data System (ADS)

Licona, Peter R.

This dissertation investigates translanguaging in an English/Spanish dual language middle school science classroom as the teacher and students worked through a curriculum unit focusing on socioscientific issues and implementing a scientific argumentation framework. Translanguaging is the process in which bilingual speakers fluidly and dynamically draw from their full linguistic repertoire to perform a communicative act. Using ethnographically informed data collection in conjunction with discourse analysis, teacher translanguaging was examined for its related functions in the science classroom and how teacher translanguaging afforded opportunities for framing and supporting scientific argumentation. Results suggest that the functions of teacher translanguaging fell into three main themes: maintaining classroom culture, facilitating the academic task, and framing epistemic practices. Of the three categories of translanguaging, framing epistemic practices proved to be of paramount importance in the teacher presenting and supporting the practice of scientific argumentation. Implications from this study are relevant for pre-service science teacher preparation and in-service science teacher professional development for teachers working with emergent bilingual students.

Life course experiences and lay diagnosis explain low-income parents' child dental decisions: a qualitative study.

This study aimed to better understand low-income parents' child dental care decisions through a life course approach that captured parents' experiences within the social context of poverty. We conducted 43 qualitative life history interviews with 10 parents, who were long-term social assistance recipients living in Montreal, Canada. Thematic analysis involved interview debriefing, transcript coding, theme identification and data interpretation. Our interviews identified two emergent themes: lay diagnosis and parental oral health management. Parents described a process of 'lay diagnosis' that consisted of examining their children's teeth and interpreting their children's oral signs and symptoms based on their observations. These lay diagnoses were also shaped by their own dental crises, care experiences and oral health knowledge gained across a life course of poverty and dental disadvantage. Parents' management strategies included monitoring and managing their children's oral health themselves or by seeking professional recourse. Parents' management strategies were influenced both by their lay diagnoses and their perceived ability to manage their children's oral health. Parents felt responsible for their children's dental care, empowered to manage their oral health and sometimes forgo dental visits for their children because of their own self-management life history. This original approach revealed insights that help to understand why low-income parents may underutilize free dental services. Further research should consider how dental programs can nurture parental empowerment and capitalize on parents' perceived ability to diagnose and manage their children's oral health.

The results favored acupuncture. Although there was little argument about the findings in the scientific press, a controversy played out in blog posts and the lay press. This controversy was characterized by ad hominem remarks, anonymous criticism, phony expertise, and the use of opinion to contradict data, predominately by self-proclaimed skeptics. There was a near complete absence of substantive scientific critque. The lack of any reasoned debate about the main findings of the Acupuncture Trialists' Collaboration paper underlines that mainstream science has moved on from the intellectual sterility and ad hominem attacks that characterize the skeptics’ movement.

Unequal brothers : are homeopathy and hormesis linked?

Oberbaum, Menachem; Frass, Michael; Gropp, Cornelius

2015-04-01

The debate between those who believe homeopathy and hormesis derive from the same root and those who believe the two are different phenomena is as old as hormesis. It is an emotionally loaded discussion, with both sides fielding arguments which are far from scientific. Careful analysis of the basic paradigms of the two systems questions the claim of the homeopaths, who find similarities between them. The authors discuss these paradigms, indicating the differences between the claims of homeopathy and hormesis. It is time for thorough and serious research to lay this question to rest. One possible approach is to compare the activity of a hormetic agent, prepared in the usual way, with that of the same agent in the same concentration prepared homeopathically by serial dilution and succussion.

How French media have portrayed ADHD to the lay public and to social workers

PubMed Central

Ponnou, Sébastien; Gonon, François

2017-01-01

ABSTRACT Two models of attention deficit hyperactivity disorder (ADHD) coexist: the biomedical and the psychosocial. We identified in nine French newspapers 159 articles giving facts and opinions about ADHD from 1995 to 2015. We classified them according to the model they mainly supported and on the basis of what argument. Two thirds (104/159) mainly supported the biomedical model. The others either defended the psychodynamic understanding of ADHD or voiced both models. Neurological dysfunctions and genetic risk factors were mentioned in support of the biomedical model in only 26 and eight articles, respectively. These biological arguments were less frequent in the most recent years. There were fewer articles mentioning medication other than asserting that medication must be combined with psychosocial interventions (14 versus 57 articles). Only 11/159 articles claimed that medication protects from school failure. These results were compared to those of our two previous studies. Thus, both French newspapers and the specialized press read by social workers mainly defended either the psychodynamic understanding of ADHD or a nuanced version of the biomedical model. In contrast, most French TV programmes described ADHD as an inherited neurological disease whose consequences on school failure can be counteracted by a very effective medication. PMID:28532330

Content Characteristics Driving the Diffusion of Antismoking Messages: Implications for Cancer Prevention in the Emerging Public Communication Environment

PubMed Central

2013-01-01

This study examined how content characteristics of antitobacco messages affect smokers’ selective exposure to and social sharing of those messages. Results from an experiment revealed that content features predicting smokers’ selection of antismoking messages are different from those predicting whether those messages are shared. Antismoking messages smokers tend to select are characterized by strong arguments (odds ratio = 2.02, P = .02) and positive sentiments (odds ratio = 3.08, P = .03). Once selected, the messages more likely to be retransmitted by smokers were those with novel arguments (B = .83, P = .002) and positive sentiments (B = 1.65, P = .005). This research adds to the literature about the content characteristics driving the social diffusion of antitobacco messages and contributes to our understanding of the role of persuasive messages about smoking cessation in the emerging public communication environment.

This article examines two influential authors who have addressed the interface between the fields of chemistry and physics and have reached opposite conclusions about whether or not emergence and downward causation represent genuine phenomena. While McLaughlin concludes that emergence is impossible in the light of quantum mechanics, Hendry regards issues connected with the status of molecular structure as supporting emergence. The present author suggests that one should not be persuaded by either of these arguments and pleads for a form of agnosticism over the reality of emergence and downward causation until further studies might be carried out.

Learning Gene Expression Through Modelling and Argumentation. A Case Study Exploring the Connections Between the Worlds of Knowledge

NASA Astrophysics Data System (ADS)

Puig, Blanca; Ageitos, Noa; Jiménez-Aleixandre, María Pilar

2017-12-01

There is emerging interest on the interactions between modelling and argumentation in specific contexts, such as genetics learning. It has been suggested that modelling might help students understand and argue on genetics. We propose modelling gene expression as a way to learn molecular genetics and diseases with a genetic component. The study is framed in Tiberghien's (2000) two worlds of knowledge, the world of "theories & models" and the world of "objects & events", adding a third component, the world of representations. We seek to examine how modelling and argumentation interact and connect the three worlds of knowledge while modelling gene expression. It is a case study of 10th graders learning about diseases with a genetic component. The research questions are as follows: (1) What argumentative and modelling operations do students enact in the process of modelling gene expression? Specifically, which operations allow connecting the three worlds of knowledge? (2) What are the interactions between modelling and argumentation in modelling gene expression? To what extent do these interactions help students connect the three worlds of knowledge and modelling gene expression? The argumentative operation of using evidence helps students to relate the three worlds of knowledge, enacted in all the connections. It seems to be a relationship among the number of interactions between modelling and argumentation, the connections between world of knowledge and students' capacity to develop a more sophisticated representation. Despite this is a case study, this approach of analysis reveals potentialities for a deeper understanding of learning genetics though scientific practices.

Metabolite exchange between microbiome members produces compounds that influence Drosophila behavior

2017-01-01

Animals host multi-species microbial communities (microbiomes) whose properties may result from inter-species interactions; however, current understanding of host-microbiome interactions derives mostly from studies in which elucidation of microbe-microbe interactions is difficult. In exploring how Drosophila melanogaster acquires its microbiome, we found that a microbial community influences Drosophila olfactory and egg-laying behaviors differently than individual members. Drosophila prefers a Saccharomyces-Acetobacter co-culture to the same microorganisms grown individually and then mixed, a response mainly due to the conserved olfactory receptor, Or42b. Acetobacter metabolism of Saccharomyces-derived ethanol was necessary, and acetate and its metabolic derivatives were sufficient, for co-culture preference. Preference correlated with three emergent co-culture properties: ethanol catabolism, a distinct volatile profile, and yeast population decline. Egg-laying preference provided a context-dependent fitness benefit to larvae. We describe a molecular mechanism by which a microbial community affects animal behavior. Our results support a model whereby emergent metabolites signal a beneficial multispecies microbiome. DOI: http://dx.doi.org/10.7554/eLife.18855.001 PMID:28068220

Digital media, the developing brain and the interpretive plasticity of neuroplasticity.

PubMed

Choudhury, Suparna; McKinney, Kelly A

2013-04-01

The use and misuse of digital technologies among adolescents has been the focus of fiery debates among parents, educators, policy-makers and in the media. Recently, these debates have become shaped by emerging data from cognitive neuroscience on the development of the adolescent brain and cognition. "Neuroplasticity" has functioned as a powerful metaphor in arguments both for and against the pervasiveness of digital media cultures that increasingly characterize teenage life. In this paper, we propose that the debates concerning adolescents are the meeting point of two major social anxieties both of which are characterized by the threat of "abnormal" (social) behaviour: existing moral panics about adolescent behaviour in general and the growing alarm about intense, addictive, and widespread media consumption in modern societies. Neuroscience supports these fears but the same kinds of evidence are used to challenge these fears and reframe them in positive terms. Here, we analyze discourses about digital media, the Internet, and the adolescent brain in the scientific and lay literature. We argue that while the evidential basis is thin and ambiguous, it has immense social influence. We conclude by suggesting how we might move beyond the poles of neuro-alarmism and neuro-enthusiasm. By analyzing the neurological adolescent in the digital age as a socially extended mind, firstly, in the sense that adolescent cognition is distributed across the brain, body, and digital media tools and secondly, by viewing adolescent cognition as enabled and transformed by the institution of neuroscience, we aim to displace the normative terms of current debates.

In resource-limited settings, identification of successful and sustainable task-shifting interventions is important for improving care. To determine whether the training of lay people to take vital signs as trauma clerks is an effective and sustainable method to increase availability of vital signs in the initial evaluation of trauma patients. We conducted a quasi-experimental study of patients presenting with traumatic injury pre- and post-intervention. The study was conducted at Kamuzu Central Hospital, a tertiary care referral hospital, in Lilongwe, Malawi. All adult (age ≥ 18 years) trauma patients presenting to emergency department over a six-month period from January to June prior to intervention (2011), immediately post-intervention (2012), 1 year post-intervention (2013) and 2 years post-intervention (2014). Lay people were trained to take and record vital signs. The number of patients with recorded vital signs pre- and post-intervention and sustainability of the intervention as determined by time-series analysis. Availability of vital signs on initial evaluation of trauma patients increased significantly post-intervention. The percentage of patients with at least one vital sign recorded increased from 23.5 to 92.1%, and the percentage of patients with all vital signs recorded increased from 4.1 to 91.4%. Availability of Glasgow Coma Scale also increased from 40.3 to 88.6%. Increased documentation of vital signs continued at 1 year and 2 years post-intervention. However, the percentage of documented vital signs did decrease slightly after the US-trained medical student and surgeon who trained the trauma clerks were no longer available in country, except for Glasgow Coma Scale. Patients who died during emergency department evaluation were significantly less likely to have vital signs recorded. The training of lay people to collect vital signs and Glasgow Coma Scale is an effective and sustainable method of task shifting in a resource-limited setting.

Effect of a surface tension imbalance on a partly submerged cylinder

NASA Astrophysics Data System (ADS)

Janssens, Stoffel; Chaurasia, Vikash; Fried, Eliot

We perform a force analysis of a circular cylinder which lays between a liquid-gas interface and acts as a barrier between a surfactant-free surface and a surfactant-loaded surface. The respective surfaces have uniform surface tensions γa and γb which generate a surface tension imbalance Δγ =γa -γb , also referred to as surface pressure. In addition to the general force analysis, we determine the effect of Δγ on the load-bearing capacity of a floating cylinder upon sinking for a specific set of parameters. Moreover, we demonstrate that Δγ induces a horizontal force component which in magnitude is equal to Δγ , when measured per unit length cylinder, and use an energetic argument to prove that this relation applies to prismatic bodies in general.

Mathematics in narratives of Geodetic expeditions.

PubMed

Terrall, Mary

2006-12-01

In eighteenth-century France, geodesy (the measure of the earth's shape) became an arena where mathematics and narrative intersected productively. Mathematics played a crucial role not only in the measurements and analysis necessary to geodesy but also in the narrative accounts that presented the results of elaborate and expensive expeditions to the reading public. When they returned to France to write these accounts after their travels, mathematician-observers developed a variety of ways to display numbers and mathematical arguments and techniques. The numbers, equations, and diagrams they produced could not be separated from the story of their acquisition. Reading these accounts for the interplay of these two aspects--the mathematical and the narrative--shows how travelers articulated the intellectual and physical difficulties of their work to enhance the value of their results for specialist and lay readers alike.

Making human junk: child labor as a health issue in the Progressive Era.

Derickson, A

1992-01-01

The adverse health effects of work on approximately 2 million employed children troubled many in the United States during the early 20th century. Advocates of reform initially built a rationale for protective legislation primarily from informal, lay observations of the broad developmental outcomes of premature employment. In this endeavor, they projected a dismal scenario of impending national deterioration. This argument received strong criticism for the inadequacy of its corroborating evidence. In response, Progressive reformers emphasized the specific, measurable consequences of particular occupations. Increasingly, liberal advocates of the exclusion of boys and girls from the work force drew upon statistical compilations of occupational injuries and illnesses diagnosed by physicians. Despite their turn toward scientism, Progressives remained somewhat ambivalent about the sufficiency of quantitative data alone to achieve their aims. Images p1282-a p1285-a PMID:1503173

Towards a richer debate on tissue engineering: a consideration on the basis of NEST-ethics.

In their 2007 paper, Swierstra and Rip identify characteristic tropes and patterns of moral argumentation in the debate about the ethics of new and emerging science and technologies (or "NEST-ethics"). Taking their NEST-ethics structure as a starting point, we considered the debate about tissue engineering (TE), and argue what aspects we think ought to be a part of a rich and high-quality debate of TE. The debate surrounding TE seems to be predominantly a debate among experts. When considering the NEST-ethics arguments that deal directly with technology, we can generally conclude that consequentialist arguments are by far the most prominently featured in discussions of TE. In addition, many papers discuss principles, rights and duties relevant to aspects of TE, both in a positive and in a critical sense. Justice arguments are only sporadically made, some "good life" arguments are used, others less so (such as the explicit articulation of perceived limits, or the technology as a technological fix for a social problem). Missing topics in the discussion, at least from the perspective of NEST-ethics, are second "level" arguments-those referring to techno-moral change connected to tissue engineering. Currently, the discussion about tissue engineering mostly focuses on its so-called "hard impacts"-quantifiable risks and benefits of the technology. Its "soft impacts"-effects that cannot easily be quantified, such as changes to experience, habits and perceptions, should receive more attention.

Witnesses of a sudden cardiac arrest play a key-role in resuscitation. Lay-persons should therefore be trained to recognize that a collapsed person who is not breathing at all or breathing normally might suffer from cardiac arrest. Information of professional emergency medical staff by lay-persons and their initiation of cardio-pulmonary-resuscitation-measures are of great importance for cardiac-arrest victims. Ambulance-dispatchers have to support lay-rescuers via telephone. This support includes the localisation of the nearest Automatic External Defibrillator (AED). Presentation of agonal breathing or convulsions due to brain-hypoxia need to be recognized as potential early signs of cardiac arrest. In any case of cardiac arrest chest-compressions need to be started. There is insufficiant data to recommend "chest-compression-only"-CPR as being equally sufficient as cardio-pulmonary-resuscitation including ventilation. Rescuers trained in ventilation should therefore combine compressions and ventilations at a 30:2-ratio. Movement of the chest is being used as a sign of sufficient ventilation. High-quality chest-compressions of at least 5 cm of depth, not exceeding 6 cm, are recommended at a ratio of 100-120 chest conpressions/min. Interruption of chest-compression should be avoided. At busy public places AED should be available to enable lay-rescuers to apply early defibrillation. © Georg Thieme Verlag Stuttgart · New York.

Social regulation of maternal traits in nest-founding bumble bee (Bombus terrestris) queens.

Woodard, S Hollis; Bloch, Guy; Band, Mark R; Robinson, Gene E

2013-09-15

During the nest-founding phase of the bumble bee colony cycle, queens undergo striking changes in maternal care behavior. Early in the founding phase, prior to the emergence of workers in the nest, queens are reproductive and also provision and feed their offspring. However, later in the founding phase, queens reduce their feeding of larvae and become specialized on reproduction. This transition is synchronized with the emergence of workers in the colony, who assume the task of feeding their siblings. Using a social manipulation experiment with the bumble bee Bombus terrestris, we tested the hypothesis that workers regulate the transition from feeding brood to specialization on reproduction in nest-founding bumble bee queens. Consistent with this hypothesis, we found that early-stage nest-founding queens with workers prematurely added to their nests reduce their brood-feeding behavior and increase egg laying, and likewise, late-stage nest-founding queens increase their brood-feeding behavior and decrease egg-laying when workers are removed from their nests. Further, brood-feeding and egg-laying behaviors were negatively correlated. We used Agilent microarrays designed from B. terrestris brain expressed sequenced tags (ESTs) to explore a second hypothesis, that workers alter brain gene expression in nest-founding queens. We found evidence that brain gene expression in nest-founding queens is altered by the presence of workers, with the effect being much stronger in late-stage founding queens. This study provides new insights into how the transition from feeding brood to specialization on reproduction in queen bumble bees is regulated during the nest initiation phase of the colony cycle.

Lay food and health worker involvement in community nutrition and dietetics in England: roles, responsibilities and relationship with professionals.

2008-06-01

Community-based food initiatives have developed in recent years with the aim of engaging previously 'hard to reach' groups. Lay workers engaged in community nutrition activities are promoted as a cost-effective mechanism for reaching underserved groups. The main objective of the study was to explore perceptions and definitions of lay food and health worker (LFHW) helping roles within the context of National Health Service (NHS) community nutrition and dietetic services in order to define the conceptual and practical elements of this new role and examine the interface with professional roles. Interpretive qualitative inquiry; semi-structured interviews with LFHW and NHS professionals employed by community-based programmes, serving 'hard-to-reach' neighbourhoods, across England. A total sampling framework was used to capture all existing and 'fully operational' lay food initiatives in England at the commencement of fieldwork (January 2002). In total, 29 professionals and 53 LFHWs were interviewed across 15 of the 18 projects identified. Although all 15 projects shared a universal goal, to promote healthy eating, this was achieved through a limited range of approaches, characterized by a narrow, individualistic focus. Lay roles spanned three broad areas: nutrition education; health promotion; and administration and personal development. Narratives from both professionals and LFHWs indicated that the primary role for LFHWs was to encourage dietary change by translating complex messages into credible and culturally appropriate advice. This research confirms the emerging discipline involving lay helping within the NHS and community dietetics. The primary role of LFHWs in the 15 projects involved was to support existing NHS services to promote healthy eating amongst 'hard to reach' communities. The activities undertaken by LFHWs are strongly influenced by professionals and the NHS. Inherent to this is a fairly narrow interpretation of health, resulting in a limited range of practice.

An Analysis of Argumentation Discourse Patterns in Elementary Teachers' Science Classroom Discussions

Kim, Sungho; Hand, Brian

2015-04-01

This multiple case study investigated how six elementary teachers' argumentation discourse patterns related to students' discussions in the science classroom. Four categories of classroom characteristics emerged through the analysis of the teachers' transcripts and recorded class periods: Structure of teacher and student argumentation, directionality, movement, and structure of student talk. Results showed that the differences between the teachers' discourse patterns were related to their modified reformed teaching observation protocol (RTOP) scores and to how the interaction of those differences affected student learning. Teachers with high RTOP scores were more likely to challenge their students' claims, explanations, and defenses and to provide less guidance and more waiting time for their students' responses than teachers with medium- and low-level RTOP scores. Students in the high-level teachers' classes challenged, defended, rejected, and supported each other's ideas with evidence and required less guidance than students in the medium-level and low-level teachers' classes.

Harms to “Others” and the Selection Against Disability View

PubMed Central

2017-01-01

Abstract In recent years, the question of whether prospective parents might have a moral obligation to select against disability in their offspring has piqued the attention of many prominent philosophers and bioethicists, and a large literature has emerged surrounding this question. Rather than looking to the most common arguments given in support of a positive response to the abovementioned question, such as those focusing on the harms disability may impose on the child created, duties and role-specific obligations, and impersonal ‘harms’, a less commonly made set of arguments is focused upon which looks to the harms that a decision not to select against disability may impose on others. Three different possible arguments supporting a limited duty of disability avoidance are thus identified and subsequently explored: harms to parents themselves, harms to existing family members, and harms to other existing members of society.

Tobacco industry sociological programs to influence public beliefs about smoking

PubMed Central

Glantz, Stanton; Landman, Anne; Cortese, Daniel K

2008-01-01

The multinational tobacco companies responded to arguments about the social costs of smoking and hazards of secondhand smoke by quietly implementing the Social Costs/Social Values project (1979–1989), which relied upon the knowledge and authoritative power of social scientists to construct an alternate cultural repertoire of smoking. Social scientists created and disseminated non-health based, pro-tobacco arguments without fully acknowledging their relationship with the industry. After the U.S. Surgeon General concluded that nicotine was addictive in 1988, the industry responded by forming “Associates for Research in the Science of Enjoyment” (c.1988–1999), whose members toured the world promoting the health benefits of the use of legal substances, including tobacco, for stress relief and relaxation, without acknowledging the industry’s role. In this paper we draw on previously secret tobacco industry documents, now available on the internet to show how both of these programs utilized academic sociologists, political scientists, anthropologists, psychologists, philosophers and economists, and allowed the industry to develop and widely disseminate friendly research through credible channels. Strategies included creating favorable surveys and opinions, infusing them into the lay press and media through press releases, articles and conferences, publishing, promoting and disseminating books, commissioning and placing favorable book reviews, providing media training for book authors and organizing media tours. These programs allowed the tobacco industry to affect public and academic discourse on the social acceptability of smoking. PMID:18164524

Forbes, Thompson Hollingsworth

2014-01-01

Care coordination has emerged as an effective model of care that contributes to healthcare reform's triple aim of decreasing costs, understanding the needs of individuals, and improving outcomes. This paper provides an argument that nurses should be the leaders of care coordination. Relationships among care coordination, nursing education, and professional values are made to show a common thread that ties the foundations of each. Benefits to outcomes and improved costs by nurses are also presented as defense for this claim. Rebuttals to arguments against this claim attempt to repudiate their worth and continue to show nursing's strategic position to assume this role. © 2014 Wiley Periodicals, Inc.

Preservice Science Teachers' Epistemological Beliefs and Informal Reasoning Regarding Socioscientific Issues

Ozturk, Nilay; Yilmaz-Tuzun, Ozgul

2017-12-01

This study investigated preservice elementary science teachers' (PSTs) informal reasoning regarding socioscientific issues (SSI), their epistemological beliefs, and the relationship between informal reasoning and epistemological beliefs. From several SSIs, nuclear power usage was selected for this study. A total of 647 Turkish PSTs enrolled in three large universities in Turkey completed the open-ended questionnaire, which assessed the participants' informal reasoning about the target SSI, and Schommer's (1990) Epistemological Questionnaire. The participants' epistemological beliefs were assessed quantitatively and their informal reasoning was assessed both qualitatively and quantitatively. The findings revealed that PSTs preferred to generate evidence-based arguments rather than intuitive-based arguments; however, they failed to generate quality evidence and present different types of evidence to support their claims. Furthermore, among the reasoning quality indicators, PSTs mostly generated supportive argument construction. Regarding the use of reasoning modes, types of risk arguments and political-oriented arguments emerged as the new reasoning modes. The study demonstrated that the PSTs had different epistemological beliefs in terms of innate ability, omniscient authority, certain knowledge, and quick learning. Correlational analyses revealed that there was a strong negative correlation between the PSTs' certain knowledge and counterargument construction, and there were negative correlations between the PSTs' innate ability, certain knowledge, and quick learning dimensions of epistemological beliefs and their total argument construction. This study has implications for both science teacher education and the practice of science education. For example, PST teacher education programs should give sufficient importance to training teachers that are skillful and knowledgeable regarding SSIs. To achieve this, specific SSI-related courses should form part of science teacher education programs.

Centrioles: active players or passengers during mitosis?

PubMed

Debec, Alain; Sullivan, William; Bettencourt-Dias, Monica

2010-07-01

Centrioles are cylinders made of nine microtubule (MT) triplets present in many eukaryotes. Early studies, where centrosomes were seen at the poles of the mitotic spindle led to their coining as "the organ for cell division". However, a variety of subsequent observational and functional studies showed that centrosomes might not always be essential for mitosis. Here we review the arguments in this debate. We describe the centriole structure and its distribution in the eukaryotic tree of life and clarify its role in the organization of the centrosome and cilia, with an historical perspective. An important aspect of the debate addressed in this review is how centrioles are inherited and the role of the spindle in this process. In particular, germline inheritance of centrosomes, such as their de novo formation in parthenogenetic species, poses many interesting questions. We finish by discussing the most likely functions of centrioles and laying out new research avenues.

Balancing the good, the bad and the better: a discursive perspective on probiotics and healthy eating.

PubMed

Koteyko, Nelya

2010-11-01

Functional foods promoted as novel food products providing health benefits beyond basic nutrition are gradually becoming part of the European food basket. Typically, research on functional food has focused on public attitudes, the acceptability of different product types, and public trust in novel food. In this article, discursive analysis of focus group discussions held in Britain with 34 users and non-users of probiotics points to the argumentative orientation of explanations for consumption of this particular type of functional food. Using the concepts of 'interpretative repertoire' and 'subject position', I explore the role of moral considerations in people's accounts of purchasing probiotics in the current context of increased health awareness and health anxiety. The analysis demonstrates how the lay accounts of eating and purchasing probiotics are entangled with notions of indulgence, individualism, as well as social norms and responsibility.

Low Fertility, Socioeconomic Development, and Gender Equity1

PubMed Central

Anderson, Thomas; Kohler, Hans-Peter

2015-01-01

While new empirical findings and theoretical frameworks provide insight into the interrelations between socioeconomic development, gender equity, and low fertility, puzzling exceptions and outliers in these findings call for a more all-encompassing framework to understand the interplay between these processes. We argue that the pace and onset of development are two important factors to be considered when analyzing gender equity and fertility. Within the developed world, “first-wave developers”—or countries that began socioeconomic development in the 19th/early 20th century – currently have much higher fertility levels than “late developers”. We lay out a novel theoretical approach to explain why this is the case and provide empirical evidence to support our argument. Our approach not only explains historical periods of low fertility but also sheds light on why there exists such large variance in fertility rates among today’s developed countries. PMID:26526031

Contrasting academic and lay press print coverage of the 2013-2016 Ebola Virus Disease outbreak

PubMed Central

Kieh, Mark D.; Cho, Elim M.

2017-01-01

Under a traditional paradigm, only those with the expected background knowledge consume academic literature. The lay press, as well as government and non-government agencies, play a complementary role of extracting findings of high interest or importance and translating them for general viewing. The need for accurate reporting and public advising is paramount when attempting to tackle epidemic outbreaks through behavior change. Yet, public trust in media outlets is at a historic low. The Crisis and Emergency Risk Communication (CERC) model for media reporting on public health emergencies was established in 2005 and has subsequently been used to analyze media reporting on outbreaks of influenza and measles as well as smoking habits and medication compliance. However, no media analysis had yet been performed on the 2013–2016 Ebola Virus Disease (EVD) outbreak. This study compared the EVD information relayed by lay press sources with general review articles in the academic literature through a mixed-methods analysis. These findings suggest that comprehensive review articles could not serve as a source to clarify and contextualize the uncertainties around the EVD outbreak, perhaps due to adherence to technical accuracy at the expense of clarity within the context of outbreak conditions. This finding does not imply inferiority of the academic literature, nor does it draw direct causation between confusion in review articles and public misunderstanding. Given the erosion of the barriers siloing academia, combined with the demands of today’s fast-paced media environment, contemporary researchers should realize that no study is outside the public forum and to therefore consider shifting the paradigm to take personal responsibility in the process of accurately translating their scientific words into public policy actions to best serve as a source of clarity.

To (1) map how different stakeholders understand telehealth and telecare technologies and (2) explore the implications for development and implementation of telehealth and telecare services. Discourse analysis. 68 publications representing diverse perspectives (academic, policy, service, commercial and lay) on telehealth and telecare plus field notes from 10 knowledge-sharing events. Following a familiarisation phase (browsing and informal interviews), we studied a systematic sample of texts in detail. Through repeated close reading, we identified assumptions, metaphors, storylines, scenarios, practices and rhetorical positions. We added successive findings to an emerging picture of the whole. Telehealth and telecare technologies featured prominently in texts on chronic illness and ageing. There was no coherent organising vision. Rather, four conflicting discourses were evident and engaged only minimally with one another's arguments. Modernist discourse presented a futuristic utopian vision in which assistive technologies, implemented at scale, would enable society to meet its moral obligations to older people by creating a safe 'smart' home environment where help was always at hand, while generating efficiency savings. Humanist discourse emphasised the uniqueness and moral worth of the individual and tailoring to personal and family context; it considered that technologies were only sometimes fit for purpose and could create as well as solve problems. Political economy discourse envisaged a techno-economic complex of powerful vested interests driving commodification of healthcare and diversion of public funds into private business. Change management discourse recognised the complicatedness of large-scale technology programmes and emphasised good project management and organisational processes. Introduction of telehealth and telecare is hampered because different stakeholders hold different assumptions, values and world views, 'talk past' each other and compete for recognition and resources. If investments in these technologies are to bear fruit, more effective inter-stakeholder dialogue must occur to establish an organising vision that better accommodates competing discourses.

Representing student achievements in science

NASA Astrophysics Data System (ADS)

Fusco, Dana; Calabrese Barton, Angela

2001-03-01

In what follows, we develop a conceptual argument for expanding current visions of performance assessment to include the following three ideals: that performance/assessment addresses the value-laden decisions about what and whose science is learned and assessed and include multiple worldviews, that performance/assessment in science simultaneously emerges in response to local needs, and that the performance/assessment is a method as well as an ongoing search for method. To make this argument, we draw together ideas raised by critical, feminist and multicultural science educators to describe an inclusive science education, one we refer to as critical science education, to raise questions about the nature and purpose of performance assessment in science education. We are particularly interested in how the science of assessment is challenged and transformed within a critical science education perspective and the conditions needed to create an equitable and inclusive practice of science and science assessment across diversity. We present a case study from a youth-led community science project in the inner city to help contextualize our argument.

The emergence of a global right to health norm--the unresolved case of universal access to quality emergency obstetric care.

PubMed

Hammonds, Rachel; Ooms, Gorik

2014-02-27

The global response to HIV suggests the potential of an emergent global right to health norm, embracing shared global responsibility for health, to assist policy communities in framing the obligations of the domestic state and the international community. Our research explores the extent to which this global right to health norm has influenced the global policy process around maternal health rights, with a focus on universal access to emergency obstetric care. In examining the extent to which arguments stemming from a global right to health norm have been successful in advancing international policy on universal access to emergency obstetric care, we looked at the period from 1985 to 2013 period. We adopted a qualitative case study approach applying a process-tracing methodology using multiple data sources, including an extensive literature review and limited key informant interviews to analyse the international policy agenda setting process surrounding maternal health rights, focusing on emergency obstetric care. We applied John Kingdon's public policy agenda setting streams model to analyse our data. Kingdon's model suggests that to succeed as a mobilising norm, the right to health could work if it can help bring the problem, policy and political streams together, as it did with access to AIDS treatment. Our analysis suggests that despite a normative grounding in the right to health, prioritisation of the specific maternal health entitlements remains fragmented. Despite United Nations recognition of maternal mortality as a human rights issue, the relevant policy communities have not yet managed to shift the policy agenda to prioritise the global right to health norm of shared responsibility for realising access to emergency obstetric care. The experience of HIV advocates in pushing for global solutions based on right to health principles, including participation, solidarity and accountability; suggest potential avenues for utilising right to health based arguments to push for policy priority for universal access to emergency obstetric care in the post-2015 global agenda.

Community First Responder (CFR) schemes support lay people to respond to medical emergencies, working closely with ambulance services. They operate widely in the UK. There has been no previous review of UK literature on these schemes. This is the first systematic scoping review of UK literature on CFR schemes, which identifies the reasons for becoming a CFR, requirements for training and feedback and confusion between the CFR role and that of ambulance service staff. This study also reveals gaps in the evidence base for CFR schemes. We conducted a systematic scoping review of the published literature, in the English language from 2000 onwards using specific search terms in six databases. Narrative synthesis was used to analyse article content. Nine articles remained from the initial search of 15,969 articles after removing duplicates, title and abstract and then full text review. People were motivated to become CFRs through an altruistic desire to help others. They generally felt rewarded by their work but recognised that the help they provided was limited by their training compared with ambulance staff. There were concerns about the possible emotional impact on CFRs responding to incidents. CFRs felt that better feedback would enhance their learning. Ongoing training and support were viewed as essential to enable CFRs to progress. They perceived that public recognition of the CFR role was low, patients sometimes confusing them with ambulance staff. Relationships with the ambulance service were sometimes ambivalent due to confusion over roles. There was support for local autonomy of CFR schemes but with greater sharing of best practice. Most studies dated from 2005 and were descriptive rather than analytical. In the UK and Australia CFRs are usually lay volunteers equipped with basic skills for responding to medical emergencies, whereas in the US they include other emergency staff as well as lay people. Opportunities for future research include exploring experiences and perceptions of patients who have been treated by CFRs and other stakeholders, while also evaluating the effectiveness and costs of CFR schemes.

Articulating uncertainty as part of scientific argumentation during model-based exoplanet detection tasks

NASA Astrophysics Data System (ADS)

Lee, Hee-Sun; Pallant, Amy; Pryputniewicz, Sarah

2015-08-01

Teaching scientific argumentation has emerged as an important goal for K-12 science education. In scientific argumentation, students are actively involved in coordinating evidence with theory based on their understanding of the scientific content and thinking critically about the strengths and weaknesses of the cited evidence in the context of the investigation. We developed a one-week-long online curriculum module called "Is there life in space?" where students conduct a series of four model-based tasks to learn how scientists detect extrasolar planets through the “wobble” and transit methods. The simulation model allows students to manipulate various parameters of an imaginary star and planet system such as planet size, orbit size, planet-orbiting-plane angle, and sensitivity of telescope equipment, and to adjust the display settings for graphs illustrating the relative velocity and light intensity of the star. Students can use model-based evidence to formulate an argument on whether particular signals in the graphs guarantee the presence of a planet. Students' argumentation is facilitated by the four-part prompts consisting of multiple-choice claim, open-ended explanation, Likert-scale uncertainty rating, and open-ended uncertainty rationale. We analyzed 1,013 scientific arguments formulated by 302 high school student groups taught by 7 teachers. We coded these arguments in terms of the accuracy of their claim, the sophistication of explanation connecting evidence to the established knowledge base, the uncertainty rating, and the scientific validity of uncertainty. We found that (1) only 18% of the students' uncertainty rationale involved critical reflection on limitations inherent in data and concepts, (2) 35% of students' uncertainty rationale reflected their assessment of personal ability and knowledge, rather than scientific sources of uncertainty related to the evidence, and (3) the nature of task such as the use of noisy data or the framing of critiquing scientists' discovery encouraged students' articulation of scientific uncertainty sources in different ways.

Distributed neural representations of logical arguments in school-age children

PubMed Central

Mathieu, Romain; Booth, James R.; Prado, Jérôme

2016-01-01

Children’s understanding of linear-order (e.g., Dan is taller than Lisa, Lisa is taller than Jess) and set-inclusion (i.e., All tulips are flowers, All flowers are plants) relationships is critical for the acquisition of deductive reasoning, i.e., the ability to reach logically valid conclusions from given premises. Behavioral and neuroimaging studies in adults suggest processing differences between these relations: While arguments that involve linear-orders may be preferentially associated with spatial processing, arguments that involve set-inclusions may be preferentially associated with verbal processing. In the present study, we used functional magnetic resonance imaging (fMRI) to investigate whether these processing differences appear during the period of elementary school in development. Consistent with previous studies in adults, we found that arguments that involve linear-order and set-inclusion relationships preferentially involve spatial and verbal brain mechanisms (respectively) in school-age children (9 to 14 year olds). Because this neural sensitivity was not related to age, it likely emerges before the period of elementary education. However, the period of elementary education might play an important role in shaping the neural processing of logical reasoning, as indicated by developmental changes in frontal and parietal regions that were dependent upon the type of relation.

Market returns? Gender and theories of change in employment relations.

PubMed

Irwin, S; Bottero, W

2000-06-01

This paper explores recent arguments about the marketization of female labour, in the context of a wider analysis of the role of concepts like 'the market' and 'individualization' in sociological accounts of change in employment relations. It will be argued that within sociology there has been a tendency for rapid, large-scale changes in employment relations to be characterized as the breakdown of social influences or structures and as the emergence of atomized, individuated market forces. In the most recent models, change in the nature of gendered positions within employment are presented in terms of a decline of social structuring and social constraint. These emergent accounts hold similarities to classical economics, and to Marx's and Weber's accounts of employment, which also characterized new forms of employment relations in terms of the emptying of their social content and their replacement by market forms. We offer an alternative, moral economy, perspective which foregrounds the continued significance of social relations in the structuring of employment and employment change. We develop the argument through an analysis of gendered patterns of employment and change in family form.

Indecent medicine: in defense of the absolute prohibition against physician participation in torture.

PubMed

Matthews, Richard S

2006-01-01

In a recent article, Gross (2004) argues that physicians in decent societies have a civic duty to aid in the torturing of suspected terrorists during emergency conditions. The argument presupposes a communitarian society in which considerations of common good override questions of individual rights, but it is also utilitarian. In the event that there is a ticking bomb and no other alternative available for defusing it, torture must be used, and physicians must play their part. In an earlier article, Jones (1980) also argues in favour of physician participation in torture, going so far as to enthusiastically endorse the allocation of research resources as well to ensure that the ability to meet emergency situations is as efficient as scientifically possible. I argue against both these views and defend the absolute prohibition against torture generally, and against any participation by physicians in particular. I show that these arguments are incompatible with liberal or decent societies, and that the institutional requirements for making torture effective would constitute an unacceptable degradation both of medical ethics and practice, as well as of political institutions in general.

To counter the ill effects of synthetic dyes, bacterial pigment production as an alternative is now one of the promising and emerging fields of research. This study was conducted to evaluate the applicability of Deinococcus genus on the egg quality traits in laying hens. In study I, 24 single comb White Leghorn layers were fed with various 1 wt % Deinococcus bacterial strains for 10 d. In study II, 84 brown Hendrix layers were fed with one of 4 diets containing 0, 0.2, 1, or 5 wt % Deinococcus sp. GKB-Aid 1995 powder for 12 wk. In study III, 60 White Leghorn laying hens were fed either with or without 1 wt % Deinococcus sp. GKB-Aid 1995 powder, 1 wt % Deinococcus sp. GKB-Aid 1995 granules, or 1 wt % Deinococcus sp. GKB-Aid 1995 oily granules for 10 successive d. In all of the experiments, feeding Deinococcus powder did not affect egg quality traits except for the yolk color. In particular, supplementation with all Deinococcus powder treatments changed the yolk color (P < 0.05) in study I, with the best pigmentation score obtained by D. grandis and Deinococcus sp. GKB-Aid 1995. Moreover, longer supplementation of Deinococcus sp. GKB-Aid 1995 in study II had a significant effect on feed conversion ratio. With these findings under consideration, the present study suggests that the Deinococcus species, especially Deinococcus sp. GKB-Aid 1995, can be an excellent candidate for improving egg yolk color in laying hens. © 2017 Poultry Science Association Inc.

Estimates of emergency operating capacity in US manufacturing and nonmanufacturing industries - Volume 1: Concepts and Methodology

Development of integrated mobilization preparedness policies requires planning estimates of available productive capacity during national emergency conditions. Such estimates must be developed in a manner to allow evaluation of current trends in capacity and the consideration of uncertainties in various data inputs and in engineering assumptions. This study developed estimates of emergency operating capacity (EOC) for 446 manufacturing industries at the 4-digit Standard Industrial Classification (SIC) level of aggregation and for 24 key nonmanufacturing sectors. This volume lays out the general concepts and methods used to develop the emergency operating estimates. The historical analysis of capacity extends from 1974 throughmore » 1986. Some nonmanufacturing industries are included. In addition to mining and utilities, key industries in transportation, communication, and services were analyzed. Physical capacity and efficiency of production were measured. 3 refs., 2 figs., 12 tabs. (JF)« less

Lay beliefs about the efficacy of self-reliance, seeking help and external control as strategies for overcoming obesity, drug addiction, marital problems, stuttering and insomnia.

PubMed

Furnham, Adrian; McDermott, Mark R

1994-07-01

This study was concerned with peoples' beliefs about the importance of twenty-four different contributors towards overcoming five relatively common personal health problems, namely: obesity, drug addiction, marital difficulties, stuttering and insomnia. One hundred and twenty-two subjects completed a five-page questionnaire indicating how effective each of these contributors were to overcoming the problems as specified. Factor analysis revealed an interpretable structure similar to previous studies (Luk and Bond, 1992): the emerging three factors were labelled ' self-reliance", "seeking help" and "external control". Multiple regression showed that few individual difference variables as measured were related to perceived relevance of the different contributors. The results were discussed in terms of subjects' beliefs concerning the value of self-reliance as opposed to seeking help, and in relation to the importance of understanding lay beliefs about the efficacy of different forms of intervention.

Radiation dose awareness and disclosure practice in paediatric emergency medicine: how far have we come?

PubMed Central

Thomas, Karen E

2016-01-01

The past decade has brought increasing coverage in the medical literature and lay media of the potential association between low-level radiation from diagnostic imaging and an increased lifetime cancer risk. Both physician and public opinion increasingly favour a greater discussion of benefit and risk with patients and their families when such imaging is being considered. Particular attention has been directed towards CT, its use in children and the emergency department setting. We will review the evolution of radiation dose awareness and knowledge among emergency physicians (EPs) alongside the parallel increase in public awareness. We will then discuss expectations for risk disclosure and the challenges faced by EPs and radiologists as we strive to provide this in a clinically balanced and meaningful way. PMID:26828973

In this commentary, I will argue that the componential and emergent views of cognitive control as defined by Cooper (2010) do not necessarily oppose each other, and I will try to make a case for their interdependence.

Then, I will comment on how some of the target articles, each from a different perspective, bring arguments in favor of this integrative view. Copyright © 2011 Cognitive Science Society, Inc.

The fragility of omics risk and benefit perceptions.

PubMed

Börner, Franziska U; Schütz, Holger; Wiedemann, Peter

2011-03-25

How do individuals judge the risks and benefits of toxicogenomics, an emerging field of research which is completely unfamiliar to them? The hypothesis is that individuals' perceptions of the risks and benefits of toxicogenomics are fragile and can by influenced by different issues and context framings as a technology. The researchers expected that the effects on risk and benefit judgements would differ between lay individuals and experts in toxicogenomics. A 2×2×2 experiment that encompassed three factors was conducted. The first factor, issue framing incorporated the field of application for the technology (therapy vs. diagnosis setting). The second factor, context framing included organisations and institutions that would profit from the technology (companies vs. regulatory agencies) and the third factor encompasses the quality of individuals' level of knowledge, for example lay vs. expert knowledge. Research results suggest the differential power of framing effects. It seems that the clues provided by context frames - but not by issue frames - are able to influence the ways in which lay people and experts process information. The findings are interpreted in the line of the fuzzy trace theory that predicts reliance on fuzzy gist representations formed by stereotypes on a wide range of judgement problem including risk and benefit perceptions.

Ethical considerations for vaccination programmes in acute humanitarian emergencies

PubMed Central

Hardie, Kate; Selgelid, Michael J; Waldman, Ronald J; Strebel, Peter; Rees, Helen; Durrheim, David N

2013-01-01

Abstract Humanitarian emergencies result in a breakdown of critical health-care services and often make vulnerable communities dependent on external agencies for care. In resource-constrained settings, this may occur against a backdrop of extreme poverty, malnutrition, insecurity, low literacy and poor infrastructure. Under these circumstances, providing food, water and shelter and limiting communicable disease outbreaks become primary concerns. Where effective and safe vaccines are available to mitigate the risk of disease outbreaks, their potential deployment is a key consideration in meeting emergency health needs. Ethical considerations are crucial when deciding on vaccine deployment. Allocation of vaccines in short supply, target groups, delivery strategies, surveillance and research during acute humanitarian emergencies all involve ethical considerations that often arise from the tension between individual and common good. The authors lay out the ethical issues that policy-makers need to bear in mind when considering the deployment of mass vaccination during humanitarian emergencies, including beneficence (duty of care and the rule of rescue), non-maleficence, autonomy and consent, and distributive and procedural justice.

The effect of decentralized behavioral decision making on system-level risk.

PubMed

Kaivanto, Kim

2014-12-01

Certain classes of system-level risk depend partly on decentralized lay decision making. For instance, an organization's network security risk depends partly on its employees' responses to phishing attacks. On a larger scale, the risk within a financial system depends partly on households' responses to mortgage sales pitches. Behavioral economics shows that lay decisionmakers typically depart in systematic ways from the normative rationality of expected utility (EU), and instead display heuristics and biases as captured in the more descriptively accurate prospect theory (PT). In turn, psychological studies show that successful deception ploys eschew direct logical argumentation and instead employ peripheral-route persuasion, manipulation of visceral emotions, urgency, and familiar contextual cues. The detection of phishing emails and inappropriate mortgage contracts may be framed as a binary classification task. Signal detection theory (SDT) offers the standard normative solution, formulated as an optimal cutoff threshold, for distinguishing between good/bad emails or mortgages. In this article, we extend SDT behaviorally by rederiving the optimal cutoff threshold under PT. Furthermore, we incorporate the psychology of deception into determination of SDT's discriminability parameter. With the neo-additive probability weighting function, the optimal cutoff threshold under PT is rendered unique under well-behaved sampling distributions, tractable in computation, and transparent in interpretation. The PT-based cutoff threshold is (i) independent of loss aversion and (ii) more conservative than the classical SDT cutoff threshold. Independently of any possible misalignment between individual-level and system-level misclassification costs, decentralized behavioral decisionmakers are biased toward underdetection, and system-level risk is consequently greater than in analyses predicated upon normative rationality. © 2014 Society for Risk Analysis.

The emergence of Model Based Systems Engineering (MBSE) in a Model Based Engineering framework has created new opportunities to improve effectiveness and efficiencies across the assurance functions. The MBSE environment supports not only system architecture development, but provides for support of Systems Safety, Reliability and Risk Analysis concurrently in the same framework. Linking to detailed design will further improve assurance capabilities to support failures avoidance and mitigation in flight systems. This also is leading new assurance functions including model assurance and management of uncertainty in the modeling environment. Further, the assurance cases, a structured hierarchal argument or model, are emerging as a basis for supporting a comprehensive viewpoint in which to support Model Based Mission Assurance (MBMA).

A multi-level model of emerging technology: An empirical study of the evolution of biotechnology from 1976 to 2003

2018-01-01

In this paper, we develop an ecological, multi-level model that can be used to study the evolution of emerging technology. More specifically, by defining technology as a system composed of a set of interacting components, we can build upon the argument of multi-level density dependence from organizational ecology to develop a distribution-independent model of technological evolution. This allows us to distinguish between different stages of component development, which provides more insight into the emergence of stable component configurations, or dominant designs. We validate our hypotheses in the biotechnology industry by using patent data from the USPTO from 1976 to 2003. PMID:29795575

Notes and comments "High and dry?" The Public Readiness and Emergency Preparedness Act and liability protection for pharmaceutical manufacturers.

PubMed

Copper, B Kurt

2007-01-01

In an era filled with fears of bioterrorism, Congress approved the Public Readiness and Emergency Preparedness Act (PREPA) to encourage development of vaccines and other countermeasures. By providing pharmaceutical manufacturers with protection from liability for potential side effects, Congress has attempted to motivate manufacturers to produce a national stockpile of countermeasures. As part of PREPA, the government established a compensatory system intended to provide compensation to persons injured by countermeasures used during a public health emergency. Although the Act provides for a compensation fund, it fails to allocate monies for that fund. Thus, in the absence of further congressional action, PREPA will not provide compensation to those injured by countermeasures. Failing to assure the American public of a compensation program constitutes bad public policy and risks inspiring potential vaccinees to refuse necessary drugs. Additionally, arguments as to the constitutionality of the Act exist should Congress fail to adequately fund the program, and the existence of those arguments undermines the purpose of the Act--namely to assure pharmaceutical manufacturers that they will not be sued into oblivion should they attempt to aid national pandemic protection. In addition to detailing both the Act and the statutory precedent for congressional attempts to spur biodefense, this Article addresses important issues of healthcare, tort, and constitutional law that will continue to manifest themselves in this new era of bioterrorism.

2017-01-01

Neurodynamic system is an emerging research field. To understand the essential motivational representations of neural activity, neurodynamics is an important question in cognitive system research. This paper is to investigate Mittag-Leffler stability of a class of fractional-order neural networks in the presence of generalized piecewise constant arguments. To identify neural types of computational principles in mathematical and computational analysis, the existence and uniqueness of the solution of neurodynamic system is the first prerequisite. We prove that the existence and uniqueness of the solution of the network holds when some conditions are satisfied. In addition, self-active neurodynamic system demands stable internal dynamical states (equilibria). The main emphasis will be then on several sufficient conditions to guarantee a unique equilibrium point. Furthermore, to provide deeper explanations of neurodynamic process, Mittag-Leffler stability is studied in detail. The established results are based on the theories of fractional differential equation and differential equation with generalized piecewise constant arguments. The derived criteria improve and extend the existing related results. Copyright © 2016 Elsevier Ltd. All rights reserved.

Explaining Leibniz equivalence as difference of non-inertial appearances: Dis-solution of the Hole Argument and physical individuation of point-events

NASA Astrophysics Data System (ADS)

Lusanna, Luca; Pauri, Massimo

"The last remnant of physical objectivity of space-time" is disclosed in the case of a continuous family of spatially non-compact models of general relativity (GR). The physical individuation of point-events is furnished by the autonomous degrees of freedom of the gravitational field (viz., the Dirac observables) which represent-as it were-the ontic part of the metric field. The physical role of the epistemic part (viz. the gauge variables) is likewise clarified as embodying the unavoidable non-inertial aspects of GR. At the end the philosophical import of the Hole Argument is substantially weakened and in fact the Argument itself dissolved, while a specific four-dimensional holistic and structuralist view of space-time (called point-structuralism) emerges, including elements common to the tradition of both substantivalism and relationism. The observables of our models undergo real temporal change: this gives new evidence to the fact that statements like the frozen-time character of evolution, as other ontological claims about GR, are model dependent.

Emergency medical systems in low- and middle-income countries: recommendations for action.

2005-01-01

Emergency medical care is not a luxury for rich countries or rich individuals in poor countries. This paper makes the point that emergency care can make an important contribution to reducing avoidable death and disability in low- and middle-income countries. But emergency care needs to be planned well and supported at all levels--at the national, provincial and community levels--and take into account the entire spectrum of care, from the occurrence of an acute medical event in the community to the provision of appropriate care at the hospital. The mix of personnel, materials, and health-system infrastructure can be tailored to optimize the provision of emergency care in settings with different levels of resource availability. The misconception that emergency care cannot be cost effective in low-income settings is demonstrably inaccurate. Emergencies occur everywhere, and each day they consume resources regardless of whether there are systems capable of achieving good outcomes. With better planning, the ongoing costs of emergency care can result in better outcomes and better cost-effectiveness. Every country and community can and should provide emergency care regardless of their place in the ratings of developmental indices. We make the case for universal access to emergency care and lay out a research agenda to fill the gaps in knowledge in emergency care. PMID:16184282

The impact of design-based modeling instruction on seventh graders' spatial abilities and model-based argumentation

NASA Astrophysics Data System (ADS)

McConnell, William J.

Due to the call of current science education reform for the integration of engineering practices within science classrooms, design-based instruction is receiving much attention in science education literature. Although some aspect of modeling is often included in well-known design-based instructional methods, it is not always a primary focus. The purpose of this study was to better understand how design-based instruction with an emphasis on scientific modeling might impact students' spatial abilities and their model-based argumentation abilities. In the following mixed-method multiple case study, seven seventh grade students attending a secular private school in the Mid-Atlantic region of the United States underwent an instructional intervention involving design-based instruction, modeling and argumentation. Through the course of a lesson involving students in exploring the interrelatedness of the environment and an animal's form and function, students created and used multiple forms of expressed models to assist them in model-based scientific argument. Pre/post data were collected through the use of The Purdue Spatial Visualization Test: Rotation, the Mental Rotation Test and interviews. Other data included a spatial activities survey, student artifacts in the form of models, notes, exit tickets, and video recordings of students throughout the intervention. Spatial abilities tests were analyzed using descriptive statistics while students' arguments were analyzed using the Instrument for the Analysis of Scientific Curricular Arguments and a behavior protocol. Models were analyzed using content analysis and interviews and all other data were coded and analyzed for emergent themes. Findings in the area of spatial abilities included increases in spatial reasoning for six out of seven participants, and an immense difference in the spatial challenges encountered by students when using CAD software instead of paper drawings to create models. Students perceived 3D printed models to better assist them in scientific argumentation over paper drawing models. In fact, when given a choice, students rarely used paper drawing to assist in argument. There was also a difference in model utility between the two different model types. Participants explicitly used 3D printed models to complete gestural modeling, while participants rarely looked at 2D models when involved in gestural modeling. This study's findings added to current theory dealing with the varied spatial challenges involved in different modes of expressed models. This study found that depth, symmetry and the manipulation of perspectives are typically spatial challenges students will attend to using CAD while they will typically ignore them when drawing using paper and pencil. This study also revealed a major difference in model-based argument in a design-based instruction context as opposed to model-based argument in a typical science classroom context. In the context of design-based instruction, data revealed that design process is an important part of model-based argument. Due to the importance of design process in model-based argumentation in this context, trusted methods of argument analysis, like the coding system of the IASCA, was found lacking in many respects. Limitations and recommendations for further research were also presented.

Interaction in the dark sector

NASA Astrophysics Data System (ADS)

del Campo, Sergio; Herrera, Ramón; Pavón, Diego

2015-06-01

It may well happen that the two main components of the dark sector of the Universe, dark matter and dark energy, do not evolve separately but interact nongravitationally with one another. However, given our current lack of knowledge of the microscopic nature of these two components, there is no clear theoretical path to determine their interaction. Yet, over the years, phenomenological interaction terms have been proposed on mathematical simplicity and heuristic arguments. In this paper, based on the likely evolution of the ratio between the energy densities of these dark components, we lay down reasonable criteria to obtain phenomenological, useful, expressions of the said term independent of any gravity theory. We illustrate this with different proposals which seem compatible with the known evolution of the Universe at the background level. Likewise, we show that two possible degeneracies with noninteracting models are only apparent as they can be readily broken at the background level. Further, we analyze some interaction terms that appear in the literature.

Bias in the exchange of arguments: the case of scientists' evaluation of lay viewpoints on GM food.

Cuppen, Eefje; Hisschemøller, Matthijs; Midden, Cees

2009-09-01

Most perspectives on public participation share the notion that dialogues should be open, allowing participants to articulate and evaluate different views and knowledge claims. We hypothesize that participants' evaluation of claims may be biased because participants have a preference for a particular type or source of a claim. This would hamper an open dialogue. We tested the effect of three variables on scientists' evaluation of claims of the general public about GM food: the claim's favorability towards GM food, the phrasing, and the source of the claim. Results are based on a survey-experiment among 73 biotechnology-scientists. Biased processing occurred when scientists evaluated claims. Claims that were corresponding with the attitude of the scientists and that were phrased in a cognitive way were evaluated more positively than claims that were contrasting the attitude of the scientists and that were phrased in an affective way. Contrary to our expectation, scientists evaluated claims of the public more positively than claims of experts.

The research imperative revisited: considerations for advancing the debate surrounding medical research as moral imperative.

PubMed

Wayne, Katherine; Glass, Kathleen Cranley

2010-01-01

Medical research is frequently regarded as not only laudable, but even obligatory. However, the moral foundation for such an obligation is far from clear. Lively debate concerning the viability of an obligation to conduct and support medical research is transpiring among a small number of scholars speaking from a variety of backgrounds, yet the current discussion is predominantly situated within several discrete academic and professional circles, allowing only sporadic engagement within and between scholarly disciplines and the medical realm. We aim to lay the groundwork for a focused critique of the "research imperative" by examining (1) its commitments within ideologies of science, medicine, and progress: and (2) its normative theoretical underpinnings. Our analysis finds no solid grounding for the research imperative and exposes problems in the attitudes and arguments supporting it. We believe these concerns present compelling reasons for devoting greater critical attention to the research imperative and to the morality of the medical research enterprise as a whole.

How to Fairly Allocate Scarce Medical Resources: Ethical Argumentation under Scrutiny by Health Professionals and Lay People.

PubMed

Krütli, Pius; Rosemann, Thomas; Törnblom, Kjell Y; Smieszek, Timo

2016-01-01

Societies are facing medical resource scarcities, inter alia due to increased life expectancy and limited health budgets and also due to temporal or continuous physical shortages of resources like donor organs. This makes it challenging to meet the medical needs of all. Ethicists provide normative guidance for how to fairly allocate scarce medical resources, but legitimate decisions require additionally information regarding what the general public considers to be fair. The purpose of this study was to explore how lay people, general practitioners, medical students and other health professionals evaluate the fairness of ten allocation principles for scarce medical resources: 'sickest first', 'waiting list', 'prognosis', 'behaviour' (i.e., those who engage in risky behaviour should not be prioritized), 'instrumental value' (e.g., health care workers should be favoured during epidemics), 'combination of criteria' (i.e., a sequence of the 'youngest first', 'prognosis', and 'lottery' principles), 'reciprocity' (i.e., those who provided services to the society in the past should be rewarded), 'youngest first', 'lottery', and 'monetary contribution'. 1,267 respondents to an online questionnaire were confronted with hypothetical situations of scarcity regarding (i) donor organs, (ii) hospital beds during an epidemic, and (iii) joint replacements. Nine allocation principles were evaluated in terms of fairness for each type of scarcity along 7-point Likert scales. The relationship between demographic factors (gender, age, religiosity, political orientation, and health status) and fairness evaluations was modelled with logistic regression. Medical background was a major predictor of fairness evaluations. While general practitioners showed different response patterns for all three allocation situations, the responses by lay people were very similar. Lay people rated 'sickest first' and 'waiting list' on top of all allocation principles-e.g., for donor organs 83.8% (95% CI: [81.2%-86.2%]) rated 'sickest first' as fair ('fair' is represented by scale points 5-7), and 69.5% [66.2%-72.4%] rated 'waiting list' as fair. The corresponding results for general practitioners: 'prognosis' 79.7% [74.2%-84.9%], 'combination of criteria' 72.6% [66.4%-78.5%], and 'sickest first' 74.5% [68.6%-80.1%); these were the highest-rated allocation principles for donor organs allocation. Interestingly, only 44.3% [37.7%-50.9%] of the general practitioners rated 'instrumental value' as fair for the allocation of hospital beds during a flu epidemic. The fairness evaluations by general practitioners obtained for joint replacements: 'sickest first' 84.0% [78.8%-88.6%], 'combination of criteria' 65.6% [59.2%-71.8%], and 'prognosis' 63.7% [57.1%-70.0%]. 'Lottery', 'reciprocity', 'instrumental value', and 'monetary contribution' were considered very unfair allocation principles by both groups. Medical students' ratings were similar to those of general practitioners, and the ratings by other health professionals resembled those of lay people. Results are partly at odds with current conclusions proposed by some ethicists. A number of ethicists reject 'sickest first' and 'waiting list' as morally unjustifiable allocation principles, whereas those allocation principles received the highest fairness endorsements by lay people and to some extent also by health professionals. Decision makers are advised to consider whether or not to give ethicists, health professionals, and the general public an equal voice when attempting to arrive at maximally endorsed allocations of scarce medical resources.

Light-Front Hamiltonian Approach to the Bound-State Problem in Quantum Electrodynamics

Jones, Billy D.

1997-10-01

Why is the study of the Lamb shift in hydrogen, which at the level of detail found in this paper was largely completed by Bethe in 1947, of any real interest today? While completing such a calculation using new techniques may be very interesting for formal and academic reasons, our primary motivation is to lay groundwork for precision bound-state calculations in QCD. The Lamb shift provides an excellent pedagogical tool for illustrating light-front Hamiltonian techniques, which are not widely known; but more importantly it presents three of the central dynamical and computational problems that we must face to make these techniques useful for solving QCD: How does a constituent picture emerge in a gauge field theory? How do bound-state energy scales emerge non-perturbatively? How does rotational symmetry emerge in a non-perturbative light-front calculation?

The emergence of a global right to health norm – the unresolved case of universal access to quality emergency obstetric care

PubMed Central

2014-01-01

Background The global response to HIV suggests the potential of an emergent global right to health norm, embracing shared global responsibility for health, to assist policy communities in framing the obligations of the domestic state and the international community. Our research explores the extent to which this global right to health norm has influenced the global policy process around maternal health rights, with a focus on universal access to emergency obstetric care. Methods In examining the extent to which arguments stemming from a global right to health norm have been successful in advancing international policy on universal access to emergency obstetric care, we looked at the period from 1985 to 2013 period. We adopted a qualitative case study approach applying a process-tracing methodology using multiple data sources, including an extensive literature review and limited key informant interviews to analyse the international policy agenda setting process surrounding maternal health rights, focusing on emergency obstetric care. We applied John Kingdon's public policy agenda setting streams model to analyse our data. Results Kingdon’s model suggests that to succeed as a mobilising norm, the right to health could work if it can help bring the problem, policy and political streams together, as it did with access to AIDS treatment. Our analysis suggests that despite a normative grounding in the right to health, prioritisation of the specific maternal health entitlements remains fragmented. Conclusions Despite United Nations recognition of maternal mortality as a human rights issue, the relevant policy communities have not yet managed to shift the policy agenda to prioritise the global right to health norm of shared responsibility for realising access to emergency obstetric care. The experience of HIV advocates in pushing for global solutions based on right to health principles, including participation, solidarity and accountability; suggest potential avenues for utilising right to health based arguments to push for policy priority for universal access to emergency obstetric care in the post-2015 global agenda.

2016-09-01

In this paper, we seek to explore the inseparable role of emotions in the teaching and the learning of science at the primary school level, as we elaborate the theoretical underpinnings and personal experiences that lead us to this notion of inseparability. We situate our perspectives on the complexity of science education in primary schools, draw on existing literature on emotions in science, and present arguments for the necessity of working towards positive emotions in our work with young children and their teachers. We layer our own perspectives and experiences as teachers and as researchers onto methodological arguments through narratives to emerge with a reflective essay that seeks to highlight the importance of emotions in our work with children and their teachers in elementary school science.

Ethics and experts.

PubMed

Noble, C N

1982-06-01

Cheryl Noble discusses the emergence of applied ethics as a subdiscipline and expresses skepticism about the role of the philosopher as a technical "expert" on social problems. Peter Singer applauds the renewed interest of philosophers in social issues and points out the special advantages they may contribute to discussions of such issues. Jerry Avorn, a physician, sees a useful role for ethicists as teachers and resources for medical practitioners trained as generalists responsible for a patient's care. Daniel Wikler accepts Noble's contention that ethicists are in danger of becoming defenders of conventional morality but argues that applied analytic philosophy has contributed logical precision and vigor of argument on a number of pressing social issues. Tom Beauchamp also acknowledges validity in some of Noble's criticisms while analyzing a variety of weaknesses in her arguments.

Beliefs and beyond: what can we learn from qualitative studies of lay people’s understandings of cancer risk?

PubMed Central

Lipworth, Wendy L.; Davey, Heather M.; Carter, Stacy M.; Hooker, Claire; Hu, Wendy

2010-01-01

Abstract Background  Clinicians and public health professionals are centrally concerned with mediating risk. However, people often resist the risk‐related information that is communicated to them by experts, or have their own models of risk that conflict with expert views. Quantitative studies have clearly demonstrated the importance of health beliefs and various cognitive and emotional processes in shaping risk perception. More recently, a growing body of qualitative research has emerged, exploring lay conceptualizations, experiences and constructions of cancer risk. To date, this literature has not been synthesized. Objective  We report the findings of a synthesis of qualitative literature regarding the ways in which lay people construct and experience cancer risk. Design  We identified 87 articles and used the method of ‘thematic synthesis’ to identify and interpret key concepts from existing studies. Results  Eight analytic categories were developed: (i) perceptions of risk factors; (ii) process of risk perception; (iii) seeking control and taking responsibility (motivational factors); (iv) experiencing cancer directly; (v) constructing risk temporally; (vi) embodying risk; (vii) identifying with risk; and (viii) constructing risk in a social context. Conclusions  Qualitative enquiry can provide us with a rich and nuanced picture of the ways in which people understand, experience and construct risk and how being ‘at risk’ is managed, and can assist us in our communication with both individual patients and populations.

Early and good quality cardiopulmonary resuscitation (CPR) and the use of automated external defibrillators (AEDs) improve cardiac arrest patients' survival. However, AED peri- and post-shock/analysis pauses may reduce CPR effectiveness. The time performance of 12 different commercially available AEDs was tested in a manikin based scenario; then the AEDs recordings from the same tested models following the clinical use both in Pavia and Ticino were analyzed to evaluate the post-shock and post-analysis time. None of the AEDs was able to complete the analysis and to charge the capacitors in less than 10s and the mean post-shock pause was 6.7±2.4s. For non-shockable rhythms, the mean analysis time was 10.3±2s and the mean post-analysis time was 6.2±2.2s. We analyzed 154 AED records [104 by Emergency Medical Service (EMS) rescuers; 50 by lay rescuers]. EMS rescuers were faster in resuming CPR than lay rescuers [5.3s (95%CI 5-5.7) vs 8.6s (95%CI 7.3-10). AEDs showed different performances that may reduce CPR quality mostly for those rescuers following AED instructions. Both technological improvements and better lay rescuers training might be needed.

2017-05-01

FDA issues Drug Safety Communications (DSCs) to alert health care professionals and the public about emerging safety information affecting prescription and over-the-counter drugs. News media may amplify DSCs, but it is unclear how DSC messaging is transmitted through the media. We conducted a content analysis of the lay media coverage reaching the broadest audience to characterize the amount and content of media coverage of two zolpidem DSCs from 2013. After the first DSC, zolpidem news stories increased from 19 stories/week in the preceding 3 months to 153 following its release. Most (81%) appeared in the lay media, and 64% focused on the DSC content. After the second DSC, news stories increased from 24 stories/week in the preceding 3 months to 39 following. Among the 100 unique lay media news stories, at least half correctly reported three key DSC messages: next-day impairment and drowsiness as common safety hazards, lower doses for some but not all zolpidem products, and women's higher risk for impairment. Other DSC messages were reported in fewer than one-third of stories, such as the warning that impairment can happen even when people feel fully awake. The first-but not the second-zolpidem DSC generated high-profile news coverage. The finding that some messages were widely reported but others were not emphasizes the importance of ensuring translation of key DSC content.

Most pandemics—eg, HIV/AIDS, severe acute respiratory syndrome, pandemic influenza—originate in animals, are caused by viruses, and are driven to emerge by ecological, behavioural, or socioeconomic changes. Despite their substantial effects on global public health and growing understanding of the process by which they emerge, no pandemic has been predicted before infecting human beings. We review what is known about the pathogens that emerge, the hosts that they originate in, and the factors that drive their emergence. We discuss challenges to their control and new efforts to predict pandemics, target surveillance to the most crucial interfaces, and identify prevention strategies. New mathematical modelling, diagnostic, communications, and informatics technologies can identify and report hitherto unknown microbes in other species, and thus new risk assessment approaches are needed to identify microbes most likely to cause human disease. We lay out a series of research and surveillance opportunities and goals that could help to overcome these challenges and move the global pandemic strategy from response to pre-emption.

Does "epistemic non-signalling" ensure the peaceful coexistence of special relativity and quantum nonlocality? The possibility of an affirmative answer is of great importance to deterministic approaches to quantum mechanics given recent developments towards generalizations of Bell's theorem. By generalizations of Bell's theorem we here mean efforts that seek to demonstrate the impossibility of any deterministic theories to obey the predictions of Bell's theorem, including not only local hidden-variables theories (LHVTs) but, critically, of nonlocal hidden-variables theories (NHVTs) also, such as de Broglie-Bohm theory. Naturally, in light of the well-established experimental findings from quantum physics, whether or not a deterministic approach to quantum mechanics, including an emergent quantum mechanics, is logically possible, depends on compatibility with the predictions of Bell's theorem. With respect to deterministic NHVTs, recent attempts to generalize Bell's theorem have claimed the impossibility of any such approaches to quantum mechanics. The present work offers arguments showing why such efforts towards generalization may fall short of their stated goal. In particular, we challenge the validity of the use of the non-signalling theorem as a conclusive argument in favor of the existence of free randomness, and therefore reject the use of the non-signalling theorem as an argument against the logical possibility of deterministic approaches. We here offer two distinct counter-arguments in support of the possibility of deterministic NHVTs: one argument exposes the circularity of the reasoning which is employed in recent claims, and a second argument is based on the inconclusive metaphysical status of the non-signalling theorem itself. We proceed by presenting an entirely informal treatment of key physical and metaphysical assumptions, and of their interrelationship, in attempts seeking to generalize Bell's theorem on the basis of an ontic, foundational interpretation of the non-signalling theorem. We here argue that the non-signalling theorem must instead be viewed as an epistemic, operational theorem i.e. one that refers exclusively to what epistemic agents can, or rather cannot, do. That is, we emphasize that the non-signalling theorem is a theorem about the operational inability of epistemic agents to signal information. In other words, as a proper principle, the non-signalling theorem may only be employed as an epistemic, phenomenological, or operational principle. Critically, our argument emphasizes that the non-signalling principle must not be used as an ontic principle about physical reality as such, i.e. as a theorem about the nature of physical reality independently of epistemic agents e.g. human observers. One major reason in favor of our conclusion is that any definition of signalling or of non-signalling invariably requires a reference to epistemic agents, and what these agents can actually measure and report. Otherwise, the non-signalling theorem would equal a general "no-influence" theorem. In conclusion, under the assumption that the non-signalling theorem is epistemic (i.e. "epistemic non-signalling"), the search for deterministic approaches to quantum mechanics, including NHVTs and an emergent quantum mechanics, continues to be a viable research program towards disclosing the foundations of physical reality at its smallest dimensions.

Epidemiologic analyses have linked the frequency of human infections with Salmonella enterica subspecies enterica serovar Enteritidis to the consumption of contaminated eggs and thus to the prevalence of this pathogen in commercial egg-laying flocks. Contamination of the edible contents of eggs by Salmonella Enteritidis is a consequence of the colonization of reproductive tissues in systemically infected hens. The animal welfare implications of laying hen housing systems have been widely debated, but no definitive consensus has yet emerged about the food safety significance of poultry housing options. The present study sought to determine the effects of two different bird stocking densities on the invasion of internal organs by Salmonella Enteritidis in groups of experimentally infected laying hens housed in colony cages enriched with perching and nesting areas. In two trials, groups of laying hens were distributed at two different stocking densities into colony cages and (along with a group housed in conventional cages) orally inoculated with doses of 1.0 × 10(7) cfu of Salmonella Enteritidis. At 5 to 6 d post-inoculation, hens were euthanized and samples of internal organs were removed for bacteriologic culturing. For both trials combined, Salmonella Enteritidis was recovered at a significantly (P < 0.05) greater frequency from hens in enriched colony cages at the higher stocking density than at the lower density from livers (75.0% vs. 51.4%) and ovaries (51.4% vs. 30.6%). However, spleens from hens in enriched colony cages at the higher stocking density were significantly less often positive for Salmonella Enteritidis than from hens in conventional cages at that same density (90.3% vs. 68.1%). These results suggest that stocking density can influence the susceptibility of hens to Salmonella Enteritidis, but other housing systems parameters may also contribute to the outcome of infections.

This study examined beliefs about the causes and determinants of health, illness, and recovery in an opportunistic sample from Malaysia. In all, 371 women and 350 men completed the Health and Illness Scale, a 124-item scale that examined beliefs about current and future health, and beliefs about the causes of illness and recovery. Each of the four subscales of the Health Illness Scale were factor analysed to reveal the underlying structure. Results showed the emergence of a number of distinct factors in the case of each subscale, of which environmental, life-style, psychological, religious, and fate-related factors were fairly stable across subscales. Results also showed a number of differences in beliefs between religious groups, and that religiosity and sex were the strongest predictors of beliefs across the four subscales. The results are discussed in terms of the available cross-cultural literature on lay beliefs about health.

Access to assisted reproductive technologies in France: the emergence of the patients' voice.

PubMed

Fournier, Véronique; Berthiau, Denis; d'Haussy, Julie; Bataille, Philippe

2013-02-01

Is there any ethical justification for limiting the reproductive autonomy and not make assisted reproductive technologies available to certain prospective parents? We present and discuss the results of an interdisciplinary clinical ethics study concerning access to assisted reproductive technologies (ART) in situations which are considered as ethically problematic in France (overage or sick parents, surrogate motherhood). The study focused on the arguments that people in these situations put forward when requesting access to ART. It shows that requester's arguments are based on sound ethical values, and that their legitimacy is at least as strong as that of those used by doctors to question access to ART. Results reveal that the three implicit normative arguments that founded the law in 1994, which are still in force after the bioethics law revision in July 2011-the welfare of the child, the illegitimacy of a "right to a child," and the defense of the so called "social order"-are challenged on several grounds by requesters as reasons for limiting their reproductive autonomy. Although these results are limited to exceptional situations, they are of special interest insofar as they give voice to the requesters' own ethical concerns in the ongoing political debate over access to ART.

Reconsidering the history of type 2 diabetes in India: emerging or re-emerging disease?

PubMed

Weaver, Lesley Jo; Narayan, K M Venkat

2008-01-01

The emergence of type 2 diabetes in India, coinciding with the country's rapid economic development in the past several decades, is often characterized as a modern epidemic resulting directly from westernization. We draw on India's agricultural, linguistic, medical, economic, religious and gastronomic history to examine the possibility that type 2 diabetes mellitus may have existed in ancient India, having subsequently declined in the two centuries leading up to the present. The implications of such a possibility vis-a-vis the role of westernization in the global diabetes aetiology are discussed. Additionally, an argument is made for careful application of the terms 'westernization' and 'globalization' in discussions of chronic disease aetiology, where their often totalizing discourses may obscure the sociocultural particularities of manifestations of these conditions in various global arenas.

The effect of volunteer lay leaders on availability and sustainability of strength-training programs for older adults has not been well explored. We describe implementation of the StrongWomen strength training program by the Arkansas Cooperative Extension Service, and report on the relationship between delivery approach (agent-led, lay-led, or combination of agent- and lay-led) and program access and sustainability. All state Extension agents (n = 66) were surveyed on program implementation, continuance, and use of lay leaders. Program records were used to identify the number of trained lay leaders. Regression models were used to examine the relationship between delivery approach and group availability. Counties using lay leaders had twice as many groups as counties using only agents. There was a significant, positive relationship between the number of lay leaders and the number of groups. Counties using lay leaders were 8.3 times more likely to have continuing groups compared with counties not using lay leaders. Program continuance was significantly and positively associated with lay leader use. Lay delivery expanded access to strength training programs and increased the likelihood that programs would continue. This approach can be used to increase access to and sustainability of strength training programs, particularly in resource-constrained areas.

A public health approach to eating disorders prevention: it's time for public health professionals to take a seat at the table.

Austin, S Bryn

2012-10-09

The societal burden of eating disorders is clear, and though there is a compelling need for a public health approach to eating disorders prevention, public health professionals have yet to take up the challenge. The article lays out an argument for what steps need to be taken to bring a public health approach to eating disorders prevention. First, stock is taken of what the field has achieved so far, using tools from the prevention science literature, and, second, a research plan of action is offered that plays to the unique strengths of public health, drawing on a triggers-to-action framework from public health law. Minimal participation was found from public health professionals in eating disorders prevention research, and the vast majority of prevention research to date was found to be concentrated within the disciplines of psychology and psychiatry. Extreme disciplinary concentration of the research has led to a preponderance of individually targeted prevention strategies with little research focused on environmental targets, particularly at the macro level. New environmental initiatives are now emerging, such as a government-sponsored mass media anti-dieting campaign, and legal bans on extremely thin models in advertising, but for the most part, they have yet to be evaluated. A triggers-to-action framework, which focuses on evidentiary base, practical considerations, and political will, developed in public health law provides a basis for a strategic research plan for a public health approach to eating disorders prevention. There is enormous potential for growth in the scope and diversity of eating disorder prevention research strategies, particularly those targeting the macro environment. A public health approach will require a strategic plan for research that leverages the macro environment for prevention. The full engagement of public health professionals will bring to the field the much broader range of preventive strategies and perspectives needed to tackle the problem of eating disorders.

2012-01-01

Objective To (1) map how different stakeholders understand telehealth and telecare technologies and (2) explore the implications for development and implementation of telehealth and telecare services. Design Discourse analysis. Sample 68 publications representing diverse perspectives (academic, policy, service, commercial and lay) on telehealth and telecare plus field notes from 10 knowledge-sharing events. Method Following a familiarisation phase (browsing and informal interviews), we studied a systematic sample of texts in detail. Through repeated close reading, we identified assumptions, metaphors, storylines, scenarios, practices and rhetorical positions. We added successive findings to an emerging picture of the whole. Main findings Telehealth and telecare technologies featured prominently in texts on chronic illness and ageing. There was no coherent organising vision. Rather, four conflicting discourses were evident and engaged only minimally with one another's arguments. Modernist discourse presented a futuristic utopian vision in which assistive technologies, implemented at scale, would enable society to meet its moral obligations to older people by creating a safe ‘smart’ home environment where help was always at hand, while generating efficiency savings. Humanist discourse emphasised the uniqueness and moral worth of the individual and tailoring to personal and family context; it considered that technologies were only sometimes fit for purpose and could create as well as solve problems. Political economy discourse envisaged a techno-economic complex of powerful vested interests driving commodification of healthcare and diversion of public funds into private business. Change management discourse recognised the complicatedness of large-scale technology programmes and emphasised good project management and organisational processes. Conclusion Introduction of telehealth and telecare is hampered because different stakeholders hold different assumptions, values and world views, ‘talk past’ each other and compete for recognition and resources. If investments in these technologies are to bear fruit, more effective inter-stakeholder dialogue must occur to establish an organising vision that better accommodates competing discourses.

Radović, V; Ćurčić, L

2012-01-01

Background: The aim of the study was a recommendation and establishment the concept of the appropriate communication between public health, other competent services and population in emergency as the corner stone which guarantee that all goals which are important for community life will be achieved. Methods: We used methodology appropriate for social science: analyses of documents, historical approach and comparative analysis. Results: The finding shows the urgent need for accepting of crises and emergency risk communication principles, or some similar concepts, in Serbia, and implementing effective two way communication especially in multiethnic region. The pragmatic value of the paper lays in information about the recent improvement of health workforce and emergency services in emergencies using new concept of communication and as source of numerous useful documents published in USA and few recent Serbian examples. Conclusion: Health workforce has significant role in the process of protection of population in emergencies. Policy makers should work on finding a way to improve their coordination and communication, creating new academic programs, providing of adequate training, and financial means in order to give them different role in society and provide visibility. From other side health workforce should build back to the citizen trust in what they are doing for society welfare using all their skills and abilities. PMID:23308348

Whose interests do lay people represent? Towards an understanding of the role of lay people as members of committees

PubMed Central

Hogg, Christine; Williamson, Charlotte

2008-01-01

Increasingly, lay people are appointed as members to health service committees. The term ‘lay’ is used loosely and the reasons for involving lay people are seldom clearly defined. This paper argues that the different roles that lay people play need to be explicitly defined in order for their contributions to be realized. Although lay members of health service committees are generally assumed to be working for patients’ interests, our observations lead us to think that some lay people tend to support professionals’ or managers’ interests rather than patients’ interests as patients would define them. We suggest that lay people fall into three broad categories: supporters of dominant (professional) interests, supporters of challenging (managerial) interests and supporters of repressed (patient) interests. These alignments should be taken into account in appointments to health service bodies. Further research is needed on the alignments and roles of lay members. PMID:11286594

Emergency medical care in developing countries: is it worthwhile?

PubMed Central

Razzak, Junaid A.; Kellermann, Arthur L.

2002-01-01

Prevention is a core value of any health system. Nonetheless, many health problems will continue to occur despite preventive services. A significant burden of diseases in developing countries is caused by time-sensitive illnesses and injuries, such as severe infections, hypoxia caused by respiratory infections, dehydration caused by diarrhoea, intentional and unintentional injuries, postpartum bleeding, and acute myocardial infarction. The provision of timely treatment during life-threatening emergencies is not a priority for many health systems in developing countries. This paper reviews evidence indicating the need to develop and/or strengthen emergency medical care systems in these countries. An argument is made for the role of emergency medical care in improving the health of populations and meeting expectations for access to emergency care. We consider emergency medical care in the community, during transportation, and at first-contact and regional referral facilities. Obstacles to developing effective emergency medical care include a lack of structural models, inappropriate training foci, concerns about cost, and sustainability in the face of a high demand for services. A basic but effective level of emergency medical care responds to perceived and actual community needs and improves the health of populations. PMID:12481213

Livebearing or egg-laying mammals: 27 decisive nucleotides of FAM168.

PubMed

Pramanik, Subrata; Kutzner, Arne; Heese, Klaus

2017-05-23

In the present study, we determine comprehensive molecular phylogenetic relationships of the novel myelin-associated neurite-outgrowth inhibitor (MANI) gene across the entire eukaryotic lineage. Combined computational genomic and proteomic sequence analyses revealed MANI as one of the two members of the novel family with sequence similarity 168 member (FAM168) genes, consisting of FAM168A and FAM168B, having distinct genetic differences that illustrate diversification in its biological function and genetic taxonomy across the phylogenetic tree. Phylogenetic analyses based on coding sequences of these FAM168 genes revealed that they are paralogs and that the earliest emergence of these genes occurred in jawed vertebrates such as Callorhinchus milii. Surprisingly, these two genes are absent in other chordates that have a notochord at some stage in their lives, such as branchiostoma and tunicates. In the context of phylogenetic relationships among eukaryotic species, our results demonstrate the presence of FAM168 orthologs in vertebrates ranging from Callorhinchus milii to Homo sapiens, displaying distinct taxonomic clusters, comprised of fish, amphibians, reptiles, birds, and mammals. Analyses of individual FAM168 exons in our sample provide new insights into the molecular relationships between FAM168A and FAM168B (MANI) on the one hand and livebearing and egg-laying mammals on the other hand, demonstrating that a distinctive intermediate exon 4, comprised of 27 nucleotides, appears suddenly only in FAM168A and there in the livebearing mammals only but is absent from all other species including the egg-laying mammals.

Evolution of Multiple Sensory Systems Drives Novel Egg-Laying Behavior in the Fruit Pest Drosophila suzukii.

The rise of a pest species represents a unique opportunity to address how species evolve new behaviors and adapt to novel ecological niches [1]. We address this question by studying the egg-laying behavior of Drosophila suzukii, an invasive agricultural pest species that has spread from Southeast Asia to Europe and North America in the last decade [2]. While most closely related Drosophila species lay their eggs on decaying plant substrates, D. suzukii oviposits on ripening fruit, thereby causing substantial economic losses to the fruit industry [3-8]. D. suzukii has evolved an enlarged, serrated ovipositor that presumably plays a key role by enabling females to pierce the skin of ripe fruit [9]. Here, we explore how D. suzukii selects oviposition sites, and how this behavior differs from that of closely related species. We have combined behavioral experiments in multiple species with neurogenetics and mutant analysis in D. suzukii to show that this species has evolved a specific preference for oviposition on ripe fruit. Our results also establish that changes in mechanosensation, olfaction, and presumably gustation have contributed to this ecological shift. Our observations support a model in which the emergence of D. suzukii as an agricultural pest is the consequence of the progressive modification of several sensory systems, which collectively underlie a radical change in oviposition behavior.

Impact of the lay-off length on +Gz tolerance.

2002-07-01

There are many factors affecting pilots' +Gz-tolerance. Recently, attention of the aviation community has been focused on lay-off and it's impact on +Gz-tolerance. Pilots of the Polish Air Force (PAF) have dealt with that problem for several years now. The aim of the study was to provide insight on how lay-off periods with different duration impact +Gz-tolerance. 95 male jet pilots from the PAF participated in the study. Every one had at least two weeks lay-off period (non-medical reasons). Subjects were divided into four groups according to the length of lay-off period (2-4 weeks; 5-13 weeks; 14-26 weeks; 27-154 weeks), All pilots were subjected to a centrifuge exposure in GOR (0.1 G/s) or ROR (1.0 G/s) profiles, depending on the pre-lay-off exposure. Post-lay-off exposures were carried out directly after lay-off. 18 jet pilots without any lay-off constituted the control group. The difference between pre- and post-lay-off G-tolerance limit (-0,93 +/- 0,53) was statistically significant (p<0.01) only for one group, where lay-off period ranged between two and four weeks. No statistically significant differences were found where influence of other factors like total and yearly flight hours, heart rate gain (AHR) or physical activity measured as maximal oxygen intake were considered. 2-4 weeks of lay-off period decreases +Gz tolerance is statistically significant manner. Subsequent increase of lay-off period does not result in mean tolerance changes for group, however in certain individuals critical decrement of +Gz tolerance occurs. Total and last year flying hours, physical fitness does not modify impact of lay-off period on +Gz tolerance.

The emergence of coherence over the course of decision making.

Simon, D; Pham, L B; Le, Q A; Holyoak, K J

2001-09-01

Previous research has indicated that decision making is accompanied by an increase in the coherence of assessments of the factors related to the decision alternatives. In the present study, the authors investigated whether this coherence shift is obtained before people commit to a decision, and whether it is obtained in the course of a number of other processing tasks. College students were presented with a complex legal case involving multiple conflicting arguments. Participants rated agreement with the individual arguments in isolation before seeing the case and after processing it under various initial sets, including playing the role of a judge assigned to decide the case. Coherence shifts were observed when participants were instructed to delay making the decision (Experiment 1), to memorize the case (Experiment 2), and to comprehend the case (Experiment 3). The findings support the hypothesis that a coherence-generating mechanism operates in a variety of processing tasks, including decision making.

Mediating subpolitics in US and UK science news.

Jensen, Eric

2012-01-01

The development of therapeutic cloning research sparked a scientific controversy pitting patients' hopes for cures against religious and anti-abortion opposition. The present study investigates this controversy by examining the production and content of Anglo-American print media coverage of the branch of embryonic stem cell research known as "therapeutic cloning." Data collection included press articles about therapeutic cloning (n = 5,185) and qualitative interviews with journalists (n = 18). Patient activists and anti-abortion groups emerged as key news sources in this coverage. Significant qualitative differences in the mediation of these subpolitical groups and their arguments for and against therapeutic cloning are identified. Results suggest that the perceived human interest news value of narratives of patient suffering may give patient advocacy groups a privileged position in journalistic coverage. Finally, Ulrich Beck's theoretical arguments about subpolitics are critically applied to the results to elicit further insights.

Polymer translocation under a pulling force: Scaling arguments and threshold forces

NASA Astrophysics Data System (ADS)

Menais, Timothée

2018-02-01

DNA translocation through nanopores is one of the most promising strategies for next-generation sequencing technologies. Most experimental and numerical works have focused on polymer translocation biased by electrophoresis, where a pulling force acts on the polymer within the nanopore. An alternative strategy, however, is emerging, which uses optical or magnetic tweezers. In this case, the pulling force is exerted directly at one end of the polymer, which strongly modifies the translocation process. In this paper, we report numerical simulations of both linear and structured (mimicking DNA) polymer models, simple enough to allow for a statistical treatment of the pore structure effects on the translocation time probability distributions. Based on extremely extended computer simulation data, we (i) propose scaling arguments for an extension of the predicted translocation times τ ˜N2F-1 over the moderate forces range and (ii) analyze the effect of pore size and polymer structuration on translocation times τ .

Defibrillation within the first minutes after sudden cardiac arrest can save many quality-adjusted life years. Yet, despite enormous investments, 'healthcare' is still unable to provide this for the majority of patients. Emergency Medical Services often have a too long mean response time and many issues surround Public Access Defibrillation programs. In this article we argument that AED-equipped drones could be the 'magic bullet'. They are easily deployed and fast, and have a relatively low operational cost. As such they could rapidly bring an AED next to the victim, irrespective of most geographical circumstances, give visual feedback and situational awareness to the EMS dispatcher and thus assist a bystander to provide better CPR. Although there are many real-life barriers to actual deployment, we argument these might all get solved once we have solved the described technological issues. Copyright © 2017 Elsevier B.V.

The moral economy of austerity: analysing UK welfare reform.

PubMed

Morris, Lydia

2016-03-01

This paper notes the contemporary emergence of 'morality' in both sociological argument and political rhetoric, and analyses its significance in relation to ongoing UK welfare reforms. It revisits the idea of 'moral economy' and identifies two strands in its contemporary application; that all economies depend on an internal moral schema, and that some external moral evaluation is desirable. UK welfare reform is analysed as an example of the former, with reference to three distinct orientations advanced in the work of Freeden (1996), Laclau (2014), and Lockwood (1996). In this light, the paper then considers challenges to the reform agenda, drawn from third sector and other public sources. It outlines the forms of argument present in these challenges, based respectively on rationality, legality, and morality, which together provide a basis for evaluation of the welfare reforms and for an alternative 'moral economy'. © London School of Economics and Political Science 2016.

Fun and Games and Boredom.

Serious videogames use entertainment to teach, train, or change behavior. What began in the 1970s as tentative attempts to create learning software is now a recognized videogame genre and an emerging health science. Although more research is needed, a growing body of literature suggests serious videogames can be effective. Support for serious videogames, however, is not universal. An informal Web search reveals numerous skeptics. Critics question serious videogames' entertainment value and, thus, their viability. "How can serious videogames attract and maintain players," the argument goes, "if they aren't as much fun as commercial titles, or even any fun at all?" This article examines the argument that, to be effective, serious videogames should be overtly fun and comparable to commercial off-the-shelf videogames. It explores differences between game developer- and researcher-led projects and discusses ways serious videogames can avoid boring and alienating players. It concludes that direct comparisons between serious and commercial game entertainment values may be misdirected.

Effective Climate Communication with Difficult Audiences

Denning, S.

2015-12-01

Climate communication is often fraught with ideological baggage ("noise") that makes it very difficult to connect to audiences. In these cases, it is helpful to use "best practices" known from other fields of communication. Engaging audiences with authenticity, using plain language, respecting cultural and political differences, and a sprinkling of humor can go a long way toward establishing a connection. It's important to avoid common but polarizing tropes from popular media, and often quite helpful to frame climate issues in novel or unexpected ways that cut across entrenched political discourse. Emerging social science research Beyond ideology, climate change is Simple, Serious, and Solvable. Effective communication of these three key ideas can succeed when the science argument is carefully framed to avoid attack of the audience's ethical identity. Simple arguments from common sense and everyday experience are more successful than data. Serious consequences to values that resonate with the audience can be avoided by solutions that don't threaten those values.

Towards Improving the Integration of Undergraduate Biology and Mathematics Education

PubMed Central

Bergevin, Christopher

2010-01-01

Arguments have recently asserted the need for change in undergraduate biology education, particularly with regard to the role of mathematics. The crux of these protests is that rapidly developing technology is expanding the types of measurements and subsequent data available to biologists. Thus future generations of biologists will require a set of quantitative and analytic skills that will allow them to handle these types of data in order to tackle relevant questions of interest. In this spirit, we describe here strategies (or lessons learned) for undergraduate educators with regard to better preparing undergraduate biology majors for the new types of challenges that lay ahead. The topics covered here span a broad range, from classroom approaches to the administrative level (e.g., fostering inter-departmental communication, student advising) and beyond. A key theme here is the need for an attitude shift with regard to mathematics education by both students and faculty alike. Such a shift will facilitate the development and implementation of new teaching strategies with regard to improving integration of mathematics and biology pedagogy. PMID:23653694

Towards psychoanalytic contribution to linguistic metaphor theory.

PubMed

Caspi, Tair

2017-07-05

This paper lays out a formulation of the psychoanalytical contribution to linguistic metaphor theory. The author's main argument is that psychoanalysis can help enrich and shed light on linguistic metaphor theories, since these have focused on the cognitive aspect, to the exclusion of the role played by affect. Based on the tight link between metaphor and symbol - both configurations of figurative language - the author shall apply ideas sourced from some of the key psychoanalytic symbolization theories, focusing in particular on Klein, Winnicott, and Ogden. The course of exploration will serve to trace the unconscious emotional aspects that participate in the metaphor's mechanism, just as they participate in the symbol's workings. The study leads to the main conclusion that the intersubjective transitional space is of substantial importance to metaphor's constitution, particularly in regard to novel metaphors. Expanding the understanding of metaphor's modus operandi has important implications in conceptual clarification and for an in-depth analytical work, and is of immense significance when it comes to analytical work with patients who suffer impairment of their metaphoric ability.

[Medical errors: inevitable but preventable].

PubMed

Giard, R W

2001-10-27

Medical errors are increasingly reported in the lay press. Studies have shown dramatic error rates of 10 percent or even higher. From a methodological point of view, studying the frequency and causes of medical errors is far from simple. Clinical decisions on diagnostic or therapeutic interventions are always taken within a clinical context. Reviewing outcomes of interventions without taking into account both the intentions and the arguments for a particular action will limit the conclusions from a study on the rate and preventability of errors. The interpretation of the preventability of medical errors is fraught with difficulties and probably highly subjective. Blaming the doctor personally does not do justice to the actual situation and especially the organisational framework. Attention for and improvement of the organisational aspects of error are far more important then litigating the person. To err is and will remain human and if we want to reduce the incidence of faults we must be able to learn from our mistakes. That requires an open attitude towards medical mistakes, a continuous effort in their detection, a sound analysis and, where feasible, the institution of preventive measures.

An essay on 'health capital' and the Faustian bargains struck by workers in the globalised shipping industry.

PubMed

Bloor, Michael

2011-11-01

It has long been understood that work directly generates ill health and disability through injuries and occupational exposure to toxic and carcinogenic materials, but the more complex relationship between work and ill health that is seemingly mediated through psychological distress is more controversial. For example, the 'Karasek model', whereby high job demands coupled with limited latitude in decision making were thought to generate ill health, has not been supported in large-scale surveys. This paper postulates an alternative linking mechanism between work and health, namely Mildred Blaxter's concept of 'health capital', and specifically explores the value of the concept in understanding lay theorising about the links between labour intensification and self-perceived health: workers' perceptions that their work has become more effortful may be bracketed with their belief that their continuing employment is demanding accelerating expenditure of their health capital. The argument is illustrated by qualitative interviews with an international sample of seafarers, a proto-typically globalised labour force. 2011 The Author.

Postsynaptic ERG potassium channels limit muscle excitability to allow distinct egg-laying behavior states in C. elegans

PubMed Central

Collins, Kevin M.; Koelle, Michael R.

2013-01-01

C. elegans regulates egg laying by alternating between an inactive phase and a serotonin-triggered active phase. We found that the conserved ERG potassium channel UNC-103 enables this two-state behavior by limiting excitability of the egg-laying muscles. Using both high-speed video recording and calcium imaging of egg-laying muscles in behaving animals, we found that the muscles appear to be excited at a particular phase of each locomotor body bend. During the inactive phase, this rhythmic excitation infrequently evokes calcium transients or contraction of the egg-laying muscles. During the serotonin-triggered active phase, however, these muscles are more excitable and each body bend is accompanied by a calcium transient that drives twitching or full contraction of the egg-laying muscles. We found that ERG null mutants lay eggs too frequently, and that ERG function is necessary and sufficient in the egg-laying muscles to limit egg laying. ERG K+ channels localize to postsynaptic sites in the egg-laying muscle, and mutants lacking ERG have more frequent calcium transients and contractions of the egg-laying muscles even during the inactive phase. Thus ERG channels set postsynaptic excitability at a threshold so that further adjustments of excitability by serotonin generate two distinct behavioral states. PMID:23303953

Coherent vortical motion has been reported in a wide variety of populations including living organisms (bacteria, fishes, human crowds) and synthetic active matter (shaken grains, mixtures of biopolymers), yet a unified description of the formation and structure of this pattern remains lacking. Here we report the self-organization of motile colloids into a macroscopic steadily rotating vortex. Combining physical experiments and numerical simulations, we elucidate this collective behaviour. We demonstrate that the emergent-vortex structure lives on the verge of a phase separation, and single out the very constituents responsible for this state of polar active matter. Building on this observation, we establish a continuum theory and lay out a strong foundation for the description of vortical collective motion in a broad class of motile populations constrained by geometrical boundaries.

I'm Not a Warmist! Transcending Ideological Barriers in Climate Communication (Invited)

NASA Astrophysics Data System (ADS)

Denning, S.

2013-12-01

A wealth of social science research has shown that public perception of climate change is very strongly colored by ideological filters in which facts are evaluated based on their fit to previously held beliefs. Scientific discourse about climate change is well received by environmentalism, which confirms the fears and competitive impulses of libertarianism. When data and belief come into conflict in public discourse, belief nearly always dominates. Scientists, educators, and science communicators must acknowledge the cultural context of climate change in order to lift climate discourse out of its ideological gutter. Many communication strategies emerging from solid social-science research fail to acknowledge the ideological cultural filters through which people experience climate discourse. Emphasizing recent trends, current weather events and impacts, and especially argument from authority of expertise and consensus are effective with average audiences but trigger reflexive opposition from suspicious listeners. Beyond ideology, climate change is Simple, Serious, and Solvable. Effective communication of these three key ideas can succeed when the science argument is carefully framed to avoid attack of the audience's ethical identity. Simple arguments from common sense and everyday experience are more successful than data. Serious consequences to values that resonate with the audience can be avoided by solutions that don't threaten those values.

Surviving out-of-hospital cardiac arrest: just a matter of defibrillators?

2014-08-01

Out-of-hospital sudden cardiac arrest (OHCA) is a leading cause of death all over the world. Although the outcome of OHCA resulting from 'nonshockable' rhythms (asystole and pulseless electrical activity) is poor regardless of resuscitation efforts, 'shockable' rhythms such as ventricular tachycardia or fibrillation may carry a good prognosis if early defibrillation is performed. At present, simplified cardiopulmonary resuscitation techniques (hands-only cardiopulmonary resuscitation) and automated external defibrillators (AEDs) offer lay people the possibility to provide lifesaving treatment to OHCA victims in the critical minutes before the arrival of the emergency medical system. Programs aimed at increasing provision of cardiopulmonary resuscitation and use of AEDs by lay people have been set up in different countries, including Italy, and have contributed to improve survival rates. However, success of these programs critically depends on appropriate planning and design, and on cultural predisposition of witnesses to undertake immediate measures of resuscitation in the case of OHCA. Placement of a large number of AEDs may carry high costs and little benefits if it is uncoordinated and not preceded by educational campaigns to spread widely the 'culture of resuscitation' in the population.

An unusual case of vaginal myiasis

PubMed Central

Jones, Brian L.; Coyne, Michael

2016-01-01

Introduction: Myiasis, a term used to describe the infestation of a live animal by fly larvae, is rarely reported in human subjects. The adult fly lays its eggs on living tissue that progresses to become larvae that feed on living tissue having gone through three developmental stages known as the first, second and third instar. The larvae become pupae before finally developing into adults. Case presentation: We describe an unusual case of a 79-year-old female who collapsed in her garden and lay there for several days before presenting to her local hospital Accident and Emergency department with an infestation of larvae in her vagina labia, identified as those from the Protophormia species northern blowfly. After complete removal of the larvae using tweezers followed by cleansing of the affected area and a course of antibiotics, the patient’s condition improved. A follow-up review by the local gynaecology team revealed no evidence of further infestation. Conclusion: It is our understanding that this is the first highly unusual case of a blowfly larvae infestation to be reported in a human within the UK. PMID:28348792

Emergent traffic jams

NASA Astrophysics Data System (ADS)

Nagel, Kai; Paczuski, Maya

1995-04-01

We study a single-lane traffic model that is based on human driving behavior. The outflow from a traffic jam self-organizes to a critical state of maximum throughput. Small perturbations of the outflow far downstream create emergent traffic jams with a power law distribution P(t)~t-3/2 of lifetimes t. On varying the vehicle density in a closed system, this critical state separates lamellar and jammed regimes and exhibits 1/f noise in the power spectrum. Using random walk arguments, in conjunction with a cascade equation, we develop a phenomenological theory that predicts the critical exponents for this transition and explains the self-organizing behavior. These predictions are consistent with all of our numerical results.

The introduction of vaccination worldwide dramatically reduced the incidence of pathogenic bacterial and viral diseases. Despite the highly successful vaccination strategies, the number of cases among vaccine preventable diseases has increased in the last decade and several of those diseases are still endemic in different countries. Here we discuss some epidemiological aspects and possible arguments that may explain why ancient diseases such as, measles, polio, pertussis, diphtheria and tuberculosis are still with us.

The anti-predator role of within-nest emergence synchrony in sea turtle hatchlings.

Group formation is a common behaviour among prey species. In egg-laying animals, despite the various factors that promote intra-clutch variation leading to asynchronous hatching and emergence from nests, synchronous hatching and emergence occurs in many taxa. This synchrony may be adaptive by reducing predation risk, but few data are available in any natural system, even for iconic examples of the anti-predator function of group formation. Here, we show for the first time that increased group size (number of hatchlings emerging together from a nest) reduces green turtle (Chelonia mydas) hatchling predation. This effect was only observed earlier in the night when predation pressure was greatest, indicated by the greatest predator abundance and a small proportion of predators preoccupied with consuming captured prey. Further analysis revealed that the effect of time of day was due to the number of hatchlings already killed in an evening; this, along with the apparent lack of other anti-predatory mechanisms for grouping, suggests that synchronous emergence from a nest appears to swamp predators, resulting in an attack abatement effect. Using a system with relatively pristine conditions for turtle hatchlings and their predators provides a more realistic environmental context within which intra-nest synchronous emergence has evolved. © 2016 The Author(s).

There is a consensus that patients and the public should be involved in research in a meaningful way. However, to date, lay people have been mostly involved in developing research ideas and commenting on patient information.We previously published a paper describing our experience with lay partners conducting observations in a study of how patients in hospital are involved with their medicines. In a later part of the same study, lay partners were also involved in analysing interviews that a researcher had conducted with patients, carers and healthcare professionals about patient and carer involvement with medicines in hospital. We therefore wanted to build on our previous paper and report on our experiences with lay partners helping to conduct data analysis. We therefore interviewed the lay members and researchers involved in the analysis to find out their views.Both lay members and researchers reported that lay partners added value to the study by bringing their own perspectives and identifying further areas for the researcher to look for in the interviews. In this way researchers and lay partners were able to work together to produce a richer analysis than would have been possible from either alone. Background It is recognised that involving lay people in research in a meaningful rather than tokenistic way is both important and challenging. In this paper, we contribute to this debate by describing our experiences of lay involvement in data analysis. Methods We conducted semi-structured interviews with the lay partners and researchers involved in qualitative data analysis in a wider study of inpatient involvement in medication safety. The interviews were transcribed verbatim and coded using open thematic analysis. Results We interviewed three lay partners and the three researchers involved. These interviews demonstrated that the lay members added value to the analysis by bringing their own perspectives; these were systematically integrated into the analysis by the lead researcher to create a synergistic output. Some challenges arose, including difficulties in recruiting a diverse range of members of the public to carry out the role; however there were generally fewer challenges in data analysis than there had been with our previous experience of lay partners' involvement in data collection. Conclusions Lay members can add value to health services research by being involved in qualitative data analysis.

Outdated communication technologies in healthcare can place patient safety at risk. This study aimed to evaluate implementation of the WhatsApp messaging service within emergency surgical teams. A prospective mixed-methods study was conducted in a London hospital. All emergency surgery team members (n = 40) used WhatsApp for communication for 19 weeks. The initiator and receiver of communication were compared for response times and communication types. Safety events were reported using direct quotations. More than 1,100 hours of communication pertaining to 636 patients were recorded, generating 1,495 communication events. The attending initiated the most instruction-giving communication, whereas interns asked the most clinical questions (P < .001). The resident was the speediest responder to communication compared to the intern and attending (P < .001). The participants felt that WhatsApp helped flatten the hierarchy within the team. WhatsApp represents a safe, efficient communication technology. This study lays the foundations for quality improvement innovations delivered over smartphones. Copyright © 2015 Elsevier Inc.

The 2014-2015 Ebola virus disease (EVD) epidemic and international public health emergency has been referred to as a "black swan" event, or an event that is unlikely, hard to predict, and highly impactful once it occurs. The Chicago Ebola Response Network (CERN) was formed in response to EVD and is capable of receiving and managing new cases of EVD, while also laying the foundation for a public health network that can anticipate, manage, and prevent the next black swan public health event. By sharing expertise, risk, and resources among 4 major academic centers, Chicago created a sustainable network to respond to the latest in a series of public health emergencies. In this respect, CERN is a roadmap for how a region can prepare to respond to public health emergencies, thereby preventing negative impacts through planning and implementation. © The Author 2015.

How to Fairly Allocate Scarce Medical Resources: Ethical Argumentation under Scrutiny by Health Professionals and Lay People

PubMed Central

Rosemann, Thomas; Törnblom, Kjell Y.

2016-01-01

Background Societies are facing medical resource scarcities, inter alia due to increased life expectancy and limited health budgets and also due to temporal or continuous physical shortages of resources like donor organs. This makes it challenging to meet the medical needs of all. Ethicists provide normative guidance for how to fairly allocate scarce medical resources, but legitimate decisions require additionally information regarding what the general public considers to be fair. The purpose of this study was to explore how lay people, general practitioners, medical students and other health professionals evaluate the fairness of ten allocation principles for scarce medical resources: ‘sickest first’, ‘waiting list’, ‘prognosis’, ‘behaviour’ (i.e., those who engage in risky behaviour should not be prioritized), ‘instrumental value’ (e.g., health care workers should be favoured during epidemics), ‘combination of criteria’ (i.e., a sequence of the ‘youngest first’, ‘prognosis’, and ‘lottery’ principles), ‘reciprocity’ (i.e., those who provided services to the society in the past should be rewarded), ‘youngest first’, ‘lottery’, and ‘monetary contribution’. Methods 1,267 respondents to an online questionnaire were confronted with hypothetical situations of scarcity regarding (i) donor organs, (ii) hospital beds during an epidemic, and (iii) joint replacements. Nine allocation principles were evaluated in terms of fairness for each type of scarcity along 7-point Likert scales. The relationship between demographic factors (gender, age, religiosity, political orientation, and health status) and fairness evaluations was modelled with logistic regression. Results Medical background was a major predictor of fairness evaluations. While general practitioners showed different response patterns for all three allocation situations, the responses by lay people were very similar. Lay people rated ‘sickest first’ and ‘waiting list’ on top of all allocation principles—e.g., for donor organs 83.8% (95% CI: [81.2%–86.2%]) rated ‘sickest first’ as fair (‘fair’ is represented by scale points 5–7), and 69.5% [66.2%–72.4%] rated ‘waiting list’ as fair. The corresponding results for general practitioners: ‘prognosis’ 79.7% [74.2%–84.9%], ‘combination of criteria’ 72.6% [66.4%–78.5%], and ‘sickest first’ 74.5% [68.6%–80.1%); these were the highest-rated allocation principles for donor organs allocation. Interestingly, only 44.3% [37.7%–50.9%] of the general practitioners rated ‘instrumental value’ as fair for the allocation of hospital beds during a flu epidemic. The fairness evaluations by general practitioners obtained for joint replacements: ‘sickest first’ 84.0% [78.8%–88.6%], ‘combination of criteria’ 65.6% [59.2%–71.8%], and ‘prognosis’ 63.7% [57.1%–70.0%]. ‘Lottery’, ‘reciprocity’, ‘instrumental value’, and ‘monetary contribution’ were considered very unfair allocation principles by both groups. Medical students’ ratings were similar to those of general practitioners, and the ratings by other health professionals resembled those of lay people. Conclusions Results are partly at odds with current conclusions proposed by some ethicists. A number of ethicists reject ‘sickest first’ and ‘waiting list’ as morally unjustifiable allocation principles, whereas those allocation principles received the highest fairness endorsements by lay people and to some extent also by health professionals. Decision makers are advised to consider whether or not to give ethicists, health professionals, and the general public an equal voice when attempting to arrive at maximally endorsed allocations of scarce medical resources.

Lay perspectives on lay health worker roles, boundaries and participation within three UK community-based health promotion projects.

South, J; Kinsella, K; Meah, A

2012-08-01

This paper examines lay interpretations of lay health worker roles within three UK community-based health promotion projects. It argues that understanding lay health worker roles requires critical analysis of the complex interrelationships between professionals, lay workers and the communities receiving a programme. Findings are presented that are drawn from a qualitative study of lay engagement in public health programme delivery where a key objective was to examine the perspectives of community members with the experience of receiving services delivered by lay health workers. Interviews and focus groups were conducted with 46 programme recipients from three case study projects; a breastfeeding peer support service, a walking for health scheme and a neighbourhood health project. The results show how participants interpreted the function and responsibilities of lay health workers and how those roles provided personalized support and facilitated engagement in group activities. Further insights into community participation processes are provided revealing the potential for active engagement in both formal and informal roles. The paper concludes that social relationships are core to understanding lay health worker programmes and therefore analysis needs to take account of the capacity for community members to move within a spectrum of participation defined by increasing responsibility for others.

Should I lay or should I wait? Egg-laying in the two-spotted spider mite Tetranychus urticae Koch.

Optimality theory predicts that females tend to maximize their offspring survival by choosing the egg-laying site. In this context, the use of conspecific cues allows a more reliable assessment of the habitat quality. To test this hypothesis, Tetranychus urticae Koch is an appropriate biological model as it is a phytophagous mite living in group, protected against external aggression by a common web. Experiments were conducted to determine the respective influence of substrate (living substrate: bean leaf vs. non-living substrate: glass plate), silk and presence of conspecific eggs on the egg-laying behavior of T. urticae females. On both living and non-living substrates, the presence of silk positively influenced the probability of a female to lay an egg, but had no influence on the number of eggs deposited. The egg-laying behavior was mainly determined by the nature of the substrate with mites laying fewer eggs on a non-living substrate than on a living one. The presence of a conspecific egg had no impact on either the probability of laying an egg or on the oviposition rate. This study showed a high variability among females in their fecundity and egg-laying performance. The physiology of females (individual fecundity), the egg-laying substrate and to a lesser extent the presence of silk impacted on the decision of spider mites to lay eggs.

The purpose of the study was to explore colorectal cancer survivors' health perceptions following cessation of active treatment for cancer and to explore the factors influencing participation in health-promoting behaviors that may help reduce cardiovascular disease risk. Face-to-face interviews were conducted with participants that had completed active treatment for cancer within the previous 2 years. Participants were colorectal cancer survivors (N = 24, men = 11, women = 13, M age = 69.38 years, SD = 4.19) recruited from a private hospital in Perth, Australia on the basis that they had existing morbidities that put them at increased risk of cardiovascular disease. Interview transcripts were analyzed using thematic analysis. Five main themes emerged: back to normal; the pleasures in life: 'is it worth it?'; beliefs about health behavior; skepticism of eating guidelines; and lack of motivation. The majority of participants felt they were in good health and had made a full recovery. Participants questioned whether it was worth changing their lifestyle given their life stage and referred to the desire to enjoy life. Lay health beliefs, skepticism of eating guidelines, and a lack of motivation were barriers to change. Interventions should target lay beliefs and skepticism in relation to health behaviors in order to reinforce the importance and value of participating in health-related behavior. Findings may inform the development of effective, patient-centered interventions that target lay health beliefs and build motivation for health behavior change.

Perceptions of community participation and health gain in a community project for the South Asian population: a qualitative study.

PubMed

Bandesha, G; Litva, A

2005-09-01

The new public health rejects old individualist attempts at improving health and embraces community-based approaches in reducing health inequalities. Primary Care Trusts in England face the challenge of converting community participation in health into reality. This study explores differences in perception of participation between lay and professional stakeholders of a community health project for a South Asian population in Greater Manchester. In-depth interviews and focus groups were used to explore the views of professional and lay stakeholders. All data were audio-taped, transcribed and analysed for emerging themes using a qualitative framework. Professionals talked of working in partnership with the community but lay stakeholders did not feel that they had control over the project. There were problems in engaging the community and local health professionals in the project. Lack of cultural awareness hampered participation in the project. There was agreement that the project improved the self-confidence of participants and created a more informed population. However, there was little support for claims of improvements in social cohesion and changes in lifestyle directly as a result of the project. Converting the rhetoric of community participation in health into reality is a greater challenge than was envisaged by policy makers. Marginalized communities may not be willing participants and issues of language and cultural sensitivity are important. Project outcomes need to be agreed to ensure projects are evaluated appropriately. Projects with South Asian communities should not be seen to be dealing with all 'ethnic health' issues without addressing changes in statutory organizations and other wider social determinants of health.

How women with high risk pregnancies use lay information when considering place of birth: A qualitative study.

Lee, Suzanne; Holden, Des; Ayers, Susan

2016-02-01

Where to give birth is a key decision in pregnancy. Women use information from family, friends and other sources besides healthcare professionals when contemplating this decision. This study explored women's use of lay information during high risk pregnancies in order to examine differences and similarities in the use of information in relation to planned place of birth. Half the participants were planning hospital births and half were planning to give birth at home. A qualitative study using semi-structured interviews set in a hospital maternity department in South East England. Twenty-six participants with high risk pregnancies, at least 32 weeks pregnant. Results were analysed using thematic analysis. Three themes emerged: approaches to research - how much information women chose to seek out and from which sources; selection of sources - how women decided which sources they considered reliable; and unhelpful research - information they considered unhelpful. Women planning homebirths undertook more research than women planning to give birth in hospital and were more likely to seek out alternative sources of information. Women from both groups referred to deliberately seeking out sources of information which reflected their own values and so did not challenge their decisions. There are similarities and differences in the use of lay information between women who plan to give birth in hospital and those who plan homebirths. Professionals working with women with high risk pregnancies should consider these factors when interacting with these women. Copyright © 2015 Australian College of Midwives.

[Sudden cardiac death out of the hospital and early defibrillation].

PubMed

Marín-Huerta, E; Peinado, R; Asso, A; Loma, A; Villacastín, J P; Muñiz, J; Brugada, J

2000-06-01

Since most sudden cardiac death victims show neither symptoms before the event nor other signs or risk factors that would have identified them as a high risk population before their cardiac arrest, emergency out-of-hospital medical services must be improved in order to obtain a higher survival in these patients. Early defibrillation is an essential part of the chain of survival that also includes the early identification of the victim, activation of the emergency medical system, immediate arrival of trained personnel who can perform basic cardiopulmonary resuscitation and early initiation of advanced cardiac life support that would raise the survival rate for sudden cardiac arrest victims. Many studies have demonstrated the enormous importance of early defibrillation in patients with a cardiac arrest due to ventricular fibrillation. The most important predictor of survival in these individuals is the time that elapses until electric defibrillation, the longer the time to defbrillation the lower the number of patients who are eventually discharged. Multiple studies have demonstrated that automatic external defibrillation will reduce the time elapsed to defibrillation and thus improve survival. For these reason, public access defibrillation to allow the use of automatic external defibrillators by minimally trained members of the lay public, has received increasing interest on the part of a groving number of companies, cities or countries. The automatic external defibrillaton, as performed by a lay person is being investigated. The liberalization of its application, if is demonstrated to be effective, will need to be accompanied by legal measures to endorse it and appropriate health education, probably during secondary education.

Adult pollen diet essential for egg maturation by a solitary Osmia bee.

PubMed

Cane, James H

2016-12-01

Reproduction is a nutritionally costly activity for many insects, as their eggs are rich in lipids and proteins. That cost seems especially acute for non-social bees, which for their size, lay enormous eggs. All adult female bees visit flowers, most of them to collect pollen and nectar, or sometimes oils, to feed their progeny. For adult bees, the need for pollen feeding has only been detailed for the honey bee, Apis mellifera. To experimentally test for the reproductive value of adult pollen feeding by a non-social bee, Osmia californica (Hymenoptera: Apiformes: Megachilidae), young female bees plus males were released into large glasshouse cages provided with either a male-fertile sunflower cultivar or a pollen-less one. Females regularly visited and drank nectar from flowers of both cultivars. Abundant orange pollen was seen regularly in guts of females confined with the male-fertile sunflowers, indicative of active pollen ingestion. All females' terminal oocytes (next egg to be laid) were small at emergence. Oocytes of females confined with the pollen-less sunflowers remained small, despite frequent nectaring and exposure to other floral stimuli. In contrast, the basal oocytes of female O. californica with access to pollen had swelled to full size within ten days following emergence, enabling them to lay eggs in provided nest tubes. Adult females of this solitary bee required dietary pollen to reproduce; nitrogen stores acquired as larvae were inadequate. Early and regular pollen feeding in part paces the onset and maximum tempo of solitary bees' lifetime reproductive output. Published by Elsevier Ltd.

Ethical aspects of creating human-nonhuman chimeras capable of human gamete production and human pregnancy.

Palacios-González, César

2015-01-01

In this paper I explore some of the moral issues that could emerge from the creation of human-nonhuman chimeras (HNH-chimeras) capable of human gamete production and human pregnancy. First I explore whether there is a cogent argument against the creation of HNH-chimeras that could produce human gametes. I conclude that so far there is none, and that in fact there is at least one good moral reason for producing such types of creatures. Afterwards I explore some of the moral problems that could emerge from the fact that a HNH-chimera could become pregnant with a human conceptus. I focus on two sets of problems: problems that would arise by virtue of the fact that a human is gestated by a nonhuman creature, and problems that would emerge from the fact that such pregnancies could affect the health of the HNH-chimera.

Causation and the origin of life. Metabolism or replication first?

PubMed

Pross, Addy

2004-06-01

The conceptual gulf that separates the 'metabolism first' and 'replication first' mechanisms for the emergence of life continues to cloud the origin of life debate. In the present paper we analyze this aspect of the origin of life problem and offer arguments in favor of the 'replication first' school. Utilizing Wicken's two-tier approach to causation we argue that a causal connection between replication and metabolism can only be demonstrated if replication would have preceded metabolism. In conjunction with existing empirical evidence and theoretical reasoning, our analysis concludes that there is no substantive evidence for a 'metabolism first' mechanism for life's emergence, while a coherent case can be made for the 'replication first' group of mechanisms. The analysis reaffirms our conviction that life is an extreme expression of kinetic control, and that the emergence of metabolic pathways can be understood by considering life as a manifestation of 'replicative chemistry'.

Interpretive analysis of 85 systematic reviews suggests that narrative syntheses and meta‐analyses are incommensurate in argumentation

2016-01-01

Using Toulmin's argumentation theory, we analysed the texts of systematic reviews in the area of workplace health promotion to explore differences in the modes of reasoning embedded in reports of narrative synthesis as compared with reports of meta‐analysis. We used framework synthesis, grounded theory and cross‐case analysis methods to analyse 85 systematic reviews addressing intervention effectiveness in workplace health promotion. Two core categories, or ‘modes of reasoning’, emerged to frame the contrast between narrative synthesis and meta‐analysis: practical–configurational reasoning in narrative synthesis (‘what is going on here? What picture emerges?’) and inferential–predictive reasoning in meta‐analysis (‘does it work, and how well? Will it work again?’). Modes of reasoning examined quality and consistency of the included evidence differently. Meta‐analyses clearly distinguished between warrant and claim, whereas narrative syntheses often presented joint warrant–claims. Narrative syntheses and meta‐analyses represent different modes of reasoning. Systematic reviewers are likely to be addressing research questions in different ways with each method. It is important to consider narrative synthesis in its own right as a method and to develop specific quality criteria and understandings of how it is carried out, not merely as a complement to, or second‐best option for, meta‐analysis. © 2016 The Authors.

2017-01-01

Lay consultations can facilitate or impede healthcare. However, little is known about how lay consultations for symptom evaluation affect treatment decision-making. The purpose of this study was to explore the role of lay consultations in symptom evaluation prior to hospitalization among patients with heart failure. Semi-structured interviews were conducted with 60 patients hospitalized for acute decompensated heart failure. Chi-square and Fisher's exact tests, along with logistic regression were used to characterize lay consultations in this sample. A large proportion of patients engaged in lay consultations for symptom evaluation and decision-making before hospitalization. Lay consultants provided attributions and advice and helped make the decision to seek medical care. Men consulted more often with their spouse than women, while women more often consulted with adult children. Findings have implications for optimizing heart failure self-management interventions, improving outcomes, and reducing hospital readmissions.

Social Responsibility and the State's Duty to provide Healthcare: An Islamic Ethico-Legal Perspective.

PubMed

Padela, Aasim I

2017-12-01

The United Nations Educational, Scientific and Cultural Organization's (UNESCO) Declaration on Bioethics and Human Rights asserts that governments are morally obliged to promote health and to provide access to quality healthcare, essential medicines and adequate nutrition and water to all members of society. According to UNESCO, this obligation is grounded in a moral commitment to promoting fundamental human rights and emerges from the principle of social responsibility. Yet in an era of ethical pluralism and contentions over the universality of human rights conventions, the extent to which the UNESCO Declaration can motivate behaviors and policies rests, at least in part, upon accepting the moral arguments it makes. In this essay I reflect on a state's moral obligation to provide healthcare from the perspective of Islamic moral theology and law. I examine how Islamic ethico-legal conceptual analogues for human rights and communal responsibility, ḥuqūq al-'ibād and farḍ al-kifāyah and other related constructs might be used to advance a moral argument for healthcare provision by the state. Moving from theory to application, I next illustrate how notions of human rights and social responsibility were used by Muslim stakeholders to buttress moral arguments to support American healthcare reform. In this way, the paper advance discourses on a universal bioethics and common morality by bringing into view the concordances and discordances between Islamic ethico-legal constructs and moral arguments advanced by transnational health policy advocates. It also provides insight into applied Islamic bioethics by demonstrating how Islamic ethico-legal values might inform the discursive outputs of Muslim organizations. © 2016 John Wiley & Sons Ltd.

The emerging public discourse on state legalization of marijuana for recreational use in the US: Analysis of news media coverage, 2010-2014.

US states have begun to legalize marijuana for recreational use. In the absence of clear scientific evidence regarding the likely public health consequences of legalization, it is important to understand how the risks and benefits of this policy are being discussed in the national dialogue. To assess the public discourse on recreational marijuana policy, we assessed the volume and content of US news media coverage of the topic. We analyzed the content of a 20% random sample of news stories published/aired in high circulation/viewership print, television, and Internet news sources from 2010 to 2014 (N=610). News media coverage of recreational marijuana policy was heavily concentrated in news outlets from the four states (AK, CO, OR, WA) and DC that legalized marijuana for recreational use during the study period. Overall, 53% of news stories mentioned pro-legalization arguments and 47% mentioned anti-legalization arguments. The most frequent pro-legalization arguments posited that legalization would reduce criminal justice involvement/costs (20% of news stories) and increase tax revenue (19%). Anti-legalization arguments centered on adverse public health consequences, such as detriments to youth health and well-being (22%) and marijuana-impaired driving (6%). Some evidence-informed public health regulatory options, like marketing and packaging restrictions, were mentioned in 5% of news stories or fewer. As additional states continue to debate legalization of marijuana for recreational use, it is critical for the public health community to develop communication strategies that accurately convey the rapidly evolving research evidence regarding recreational marijuana policy.

2017-01-01

Introduction: The Veterans Health Administration (VHA), the largest integrated healthcare delivery system in the United States, is charged with ensuring timely access to high-quality care for veterans during disasters, and supporting national, state, local, and tribal emergency management and homeland security efforts. In 2008, the VHA Office of Public Health (OPH) sponsored the first VHA Emergency Management Research Agenda-setting conference to develop research priorities that address the needs of veterans and to position VHA as a national leader in emergency management by having VHA serve as a “laboratory” for the development of evidence-based emergency management practices. Methods: We focused on four steps: #1: Appraising the emergency management research portfolio of VHA-based researchers; #2: Obtaining systematic information on VHA’s role in emergency management and the healthcare needs of veterans during disasters; #3: Based upon gaps between the current research portfolio and the existing evidence base, identifying strategic priorities using a research agenda-setting conference; and #4: Laying the groundwork to foster the conduct of emergency management research within VHA. Results: Identified research priorities included how to prevent and treat behavioral health problems related to a disaster, the efficacy of training programs, crisis communication strategies, workforce resilience, and evacuating veterans from health care facilities. Conclusion: VHA is uniquely situated to answer research questions that cannot be readily addressed in other settings. VHA should partner with other governmental and private entities to build on existing work and establish shared research priorities. PMID:28439447

Lay obligations in professional relations.

PubMed

Benjamin, M

1985-02-01

Little has been written recently about the obligations of lay people in professional relationships. Yet the Code of Medical Ethics adopted by the American Medical Association in 1847 included an extensive statement on "Obligations of patients to their physicians'. After critically examining the philosophical foundations of this statement, I provide an alternative account of lay obligations in professional relationships. Based on a hypothetical social contract and included in a full specification of professional as well as lay obligations, this account requires lay people to honor commitments and disclose relevant information. Ethically, the account assumes that all parties in lay-professional relationships should be given equal consideration and respect in determining rights and obligations. Factually, it assumes that the treatment of many illnesses and injuries required collaboration and cooperation among lay persons and health professionals, that medical resources and personnel are limited, and that medicine, nursing, and related health professions, are, in MacIntyre's sense, practices.

Equilibration, thermalisation, and the emergence of statistical mechanics in closed quantum systems

2016-05-01

We review selected advances in the theoretical understanding of complex quantum many-body systems with regard to emergent notions of quantum statistical mechanics. We cover topics such as equilibration and thermalisation in pure state statistical mechanics, the eigenstate thermalisation hypothesis, the equivalence of ensembles, non-equilibration dynamics following global and local quenches as well as ramps. We also address initial state independence, absence of thermalisation, and many-body localisation. We elucidate the role played by key concepts for these phenomena, such as Lieb-Robinson bounds, entanglement growth, typicality arguments, quantum maximum entropy principles and the generalised Gibbs ensembles, and quantum (non-)integrability. We put emphasis on rigorous approaches and present the most important results in a unified language.

Agents with left and right dominant hemispheres and quantum statistics

We present a multiagent model illustrating the emergence of two different quantum statistics, Bose-Einstein and Fermi-Dirac, in a friendly population of individuals with the right-brain dominance and in a competitive population of individuals with the left-brain hemisphere dominance, correspondingly. Doing so, we adduce the arguments that Lefebvre’s “algebra of conscience” can be used in a natural way to describe decision-making strategies of agents simulating people with different brain dominance. One can suggest that the emergence of the two principal statistical distributions is able to illustrate different types of society organization and also to be used in order to simulate market phenomena and psychic disorders, when a switching of hemisphere dominance is involved.

Dimensions of lay health worker programmes: results of a scoping study and production of a descriptive framework.

2013-03-01

Approaches that engage and support lay health workers in the delivery of health improvement activities have been widely applied across different health issues and populations. The lack of a common terminology, inconsistency in the use of role descriptors and poor indexing of lay health worker roles are all barriers to the development of a shared evidence base for lay health worker interventions. The aim of the paper is to report results from a scoping study of approaches to involve lay people in public health roles and to present a framework for categorisation of the different dimensions of lay health worker programmes. Our scoping study comprised a systematic scoping review to map the literature on lay health worker interventions and to identify role dimensions and common models. The review, which was limited to interventions relevant to UK public health priorities, covered a total of 224 publications. The scoping study also drew on experiential evidence from UK practice. Research-based and practice-based evidence confirmed the variety of role descriptors in use and the complexity of role dimensions. Five common models that define the primary role of the lay health worker were identified from the literature. A framework was later developed that grouped features of lay health worker programmes into four dimensions: intervention, role, professional support/service and the community. More account needs to be taken of the variations that occur between lay health worker programmes. This framework, with the mapping of key categories of difference, may enable better description of lay health worker programmes, which will in turn assist in building a shared evidence base. More research is needed to examine the transferability of the framework within different contexts.

Should trained lay providers perform HIV testing? A systematic review to inform World Health Organization guidelines.

2017-12-01

New strategies for HIV testing services (HTS) are needed to achieve UN 90-90-90 targets, including diagnosis of 90% of people living with HIV. Task-sharing HTS to trained lay providers may alleviate health worker shortages and better reach target groups. We conducted a systematic review of studies evaluating HTS by lay providers using rapid diagnostic tests (RDTs). Peer-reviewed articles were included if they compared HTS using RDTs performed by trained lay providers to HTS by health professionals, or to no intervention. We also reviewed data on end-users' values and preferences around lay providers preforming HTS. Searching was conducted through 10 online databases, reviewing reference lists, and contacting experts. Screening and data abstraction were conducted in duplicate using systematic methods. Of 6113 unique citations identified, 5 studies were included in the effectiveness review and 6 in the values and preferences review. One US-based randomized trial found patients' uptake of HTS doubled with lay providers (57% vs. 27%, percent difference: 30, 95% confidence interval: 27-32, p < 0.001). In Malawi, a pre/post study showed increases in HTS sites and tests after delegation to lay providers. Studies from Cambodia, Malawi, and South Africa comparing testing quality between lay providers and laboratory staff found little discordance and high sensitivity and specificity (≥98%). Values and preferences studies generally found support for lay providers conducting HTS, particularly in non-hypothetical scenarios. Based on evidence supporting using trained lay providers, a WHO expert panel recommended lay providers be allowed to conduct HTS using HIV RDTs. Uptake of this recommendation could expand HIV testing to more people globally.

Evidence supports the implementation of task shifting to address health worker shortages that are common in resource-limited settings. However, there is need to learn from established programs to identify ways to achieve the strongest, most sustainable impact. This study examined the Botswana lay counselor cadre, a task shifting initiative, to explore effectiveness and contribution to the health workforce. This evaluation used multiple methods, including a desk review, a national lay counselor survey (n = 385; response = 94%), in-depth interviews (n = 79), lay counselors focus group discussions (n = 7), lay counselors observations (n = 25), and client exit interviews (n = 47). Interview and focus group data indicate that lay counselors contribute to essentially all HIV-related programs in Botswana and they conduct the majority of HIV tests and related counseling at public health facilities throughout the country. Interviews showed that the lay counselor cadre is making the workload of more skilled health workers more manageable and increasing HIV acceptance in communities. The average score on a work-related knowledge test was 74.5%. However for 3 questions, less than half answered correctly. During observations, lay counselors demonstrated average competence for most skills assessed and clients (97.9%) were satisfied with services received. From the survey, lay counselors generally reported being comfortable with their duties; however, some reported clinical duties that extended beyond their training and mandate. Multiple factors affecting the performance of the lay counselors were identified, including insufficient resources, such as private counseling space and HIV test kits; and technical, administrative, and supervisory support. Lay counselors are fulfilling an important role in Botswana's healthcare system, serving as the entry point into HIV care, support, and treatment services. For this and other similar task shifting initiatives, it is important that lay counselors' responsibilities are clear and that training and support are adequate to optimize their effectiveness.

During emergencies, an increasing number of messages are shared through social media platforms, becoming a primary source of information for lay people and emergency managers. Weather services and institutions have started to employ social media to deliver weather warnings even if sometimes this communication lacks in strategy. In Twitter, for example, hashtagging is very important to associate messages with certain topics; in recent years, codified hashtagging is emerging as a practical way to coordinate Twitter conversations during emergencies and quickly retrieve relevant information. In 2014, a syntax for codified hashtags for weather warning was proposed in Italy: a list of 20 hashtags, realized by combining #allertameteo (weather warning) + XXX, where final letters code the regional identification. This contribution presents a monitoring of Twitter usage of weather warning codified hashtags in Italy (since July 2015) and an analysis of different contexts.

A study was conducted to determine the response of five pea varieties (Pisum sativum L.) to damage degree of Bruchus pisorum: Glyans, Modus, Kamerton, and Svit (Ukrainian cultivars) and Pleven 4 (Bulgarian cultivar). The seeds were classified into three types: healthy seeds (type 1), damaged seeds with parasitoid emergence hole (type 2), and damaged seeds with bruchid emergence hole (type 3) and they were sown. It was found that the weight of 1000 seeds did not affect the field germination of the pea varieties. Healthy and damaged seeds with parasitoid emergence holes (first and second seed types) provide a very good opportunity for growth and development while plants from damaged seeds with bruchid emergence holes had poor germination and vigor and low productivity. These seeds cannot provide the creation of well-garnished seeding and stable crop yields. Among tested varieties, the Ukrainian variety Glyans had considerably higher seed weight, field germination, and index germination and weak egg-laying activity of B. pisorum compared to others. Use of spring pea cultivars that are weakly preferred by the pea weevil in breeding programs would reduce losses due to pea weevil and provide an environmentally safer option to its control.

Mass media representations of health issues influence public perceptions of those issues. Despite legislation prohibiting smoking in public spaces, second-hand smoke (SHS) remains a health risk in the United Kingdom (UK). Further legislation might further limit children's exposure to SHS by prohibiting smoking in private vehicles carrying children. This research was designed to determine how UK national newspapers represented the debate around proposed legislation to prohibit smoking in private vehicles carrying children. Quantitative analysis of the manifest content of 422 articles about children and SHS published in UK and Scottish newspapers between 1st January 2003 and 16th February 2014. Researchers developed a coding frame incorporating emergent themes from the data. Each article was double-coded. The frequency of relevant articles rose and fell in line with policy debate events. Children were frequently characterised as victims of SHS, and SHS was associated with various health risks. Articles discussing legislation targeting SHS in private vehicles carrying children presented supportive arguments significantly more frequently than unsupportive arguments. The relatively positive representation of legislation prohibiting smoking in vehicles carrying children is favourable to policy advocates, and potentially indicative of likely public acceptance of legislation. Our findings support two lessons that public health advocates may consider: the utility of presenting children as a vulnerable target population, and the possibility of late surges in critical arguments preceding policy events.

Should Internet Researchers Use Ill-Gotten Information?

PubMed

Douglas, David M

2017-06-26

This paper describes how the ethical problems raised by scientific data obtained through harmful and immoral conduct (which, following Stan Godlovitch, is called ill-gotten information) may also emerge in cases where data is collected from the Internet. It describes the major arguments for and against using ill-gotten information in research, and shows how they may be applied to research that either collects information about the Internet itself or which uses data from questionable or unknown sources on the Internet. Three examples (the Internet Census 2012, the PharmaLeaks study, and research into keylogger dropzones) demonstrate how researchers address the ethical issues raised by the sources of data that they use and how the existing arguments concerning the use of ill-gotten information apply to Internet research. The problems faced by researchers who collect or use data from the Internet are shown to be the same problems faced by researchers in other fields who may obtain or use ill-gotten information.

The navigation of biological hyperspace

Conway Morris, Simon

2003-04-01

A recurrent argument against the reality of biological evolution is the claim that there is insufficient time for the emergence of biological complexity. Such a view is a staple of creation "scientists", but even cosmologists and biochemists have been overheard murmuring similar sentiments. Certainly the stock response, that the scientific evidence for evolution is overwhelming, must be made. However, it is also the case that whilst the efficacity of natural selection is not in dispute, it is context-free and fails to explain the specificities of life. This observation is usually greeted with a Gallic shrug: "Yes, the biosphere is very rich, but so what?" Indeed, the standard scientific response is that evolution is dogged by contingent happenstance, with the implication that a given complexity, say intelligence, is an evolutionary fluke. This, however, is inconsistent with the ubiquity of evolutionary convergence. Here I outline the argument for such convergence providing a "road-map" of possibilities that arguably has universal applications and as importantly points to a much deeper structure to life.

Fun and Games and Boredom

Abstract Serious videogames use entertainment to teach, train, or change behavior. What began in the 1970s as tentative attempts to create learning software is now a recognized videogame genre and an emerging health science. Although more research is needed, a growing body of literature suggests serious videogames can be effective. Support for serious videogames, however, is not universal. An informal Web search reveals numerous skeptics. Critics question serious videogames' entertainment value and, thus, their viability. “How can serious videogames attract and maintain players,” the argument goes, “if they aren't as much fun as commercial titles, or even any fun at all?” This article examines the argument that, to be effective, serious videogames should be overtly fun and comparable to commercial off-the-shelf videogames. It explores differences between game developer- and researcher-led projects and discusses ways serious videogames can avoid boring and alienating players. It concludes that direct comparisons between serious and commercial game entertainment values may be misdirected. PMID:24761316

Lydon, David M; Howard, Matthew C; Wilson, Stephen J; Geier, Charles F

2015-01-01

Despite the detrimental impact of smoking on health, its prevalence remains high. Empirical research has provided insight into the many causes and effects of smoking, yet lay perceptions of smoking remain relatively understudied. The current study used a form of network analysis to gain insight into the causal attributions for smoking of both smoking and non-smoking college students. The analyses resulted in highly endorsed, complex network diagrams that conveyed the perceived causal structures of smoking. Differences in smoker and non-smoker networks emerged with smokers attributing less negative consequences to smoking behaviors. Implications for intervention are discussed. PMID:25690755

Complex adaptive systems require nursing leadership to rethink organizational work and the viability and effectiveness of teams. Much of emergent thinking about complexity and systems and organizations alter the understanding of the nature and function of teamwork and the configuration and leadership of team effort. Reflecting on basic concepts of complexity and their application to team formation, dynamics, and outcomes lays an important foundation for effectively guiding the strategic activity of systems through the focused tactical action of teams. Basic principles of complexity, their impact on teams, and the fundamental elements of team effectiveness are explored.

Medical Care of the Homeless: An American and International Issue.

Homeless persons die significantly younger than their housed counterparts. In many cases, relatively straightforward primary care issues escalate into life-threatening, expensive emergencies. Poor health outcomes driven by negative interactions between comorbid symptoms meet the definition of a health syndemic in this population. Successful primary care of patients struggling with homelessness may result in long-term lifesaving measures along with decreased expenditure to hospital systems. This primary prevention requires patience, creativity, and acknowledgment that the source of many confounders may lay outside the control of these patients. Copyright © 2016 Elsevier Inc.

The hybrid halide perovskites is a prospective material for fabrication of cost-effective optical devices. Unique perovskites properties are used for solar cells and different photonic applications. Recently, perovskite-based nanophotonics has emerged. Here, we consider perovskite like a high-refractive index dielectric material, which can be considered to be a basis for nanoparticles fabrication with Mie resonances. As a result, we fabricate and study resonant perovskite nanoparticles with different sizes. We reveal, that spherical nanoparticles show enhanced photoluminescence signal. The achieved results lay a cornerstone in the field of novel types of organic-inorganic nanophotonics devices with optical properties improved by Mie resonances.

Fermionic localization of the schwarzian theory

DOE PAGES

Stanford, Douglas; Witten, Edward

2017-10-02

The SYK model is a quantum mechanical model that has been proposed to be holographically dual to a 1 + 1-dimensional model of a quantum black hole. An emergent “gravitational” mode of this model is governed by an unusual action that has been called the Schwarzian action. It governs a reparametrization of a circle. We show that the path integral of the Schwarzian theory is one-loop exact. Here, the argument uses a method of fermionic localization, even though the model itself is purely bosonic.

Confrontational scavenging as a possible source for language and cooperation

PubMed Central

2011-01-01

The emergence of language and the high degree of cooperation found among humans seems to require more than a straightforward enhancement of primate traits. Some triggering episode unique to human ancestors was likely necessary. Here it is argued that confrontational scavenging was such an episode. Arguments for and against an established confrontational scavenging niche are discussed, as well as the probable effects of such a niche on language and co-operation. Finally, several possible directions for future research are suggested. PMID:21933413

Critical exponents of extremal Kerr perturbations

NASA Astrophysics Data System (ADS)

Gralla, Samuel E.; Zimmerman, Peter

2018-05-01

We show that scalar, electromagnetic, and gravitational perturbations of extremal Kerr black holes are asymptotically self-similar under the near-horizon, late-time scaling symmetry of the background metric. This accounts for the Aretakis instability (growth of transverse derivatives) as a critical phenomenon associated with the emergent symmetry. We compute the critical exponent of each mode, which is equivalent to its decay rate. It follows from symmetry arguments that, despite the growth of transverse derivatives, all generally covariant scalar quantities decay to zero.

Understanding the role of mirror neurons in action understanding will require more than a domain-general account.

Martin, Alia; Santos, Laurie R

2014-04-01

Cook et al. propose that mirror neurons emerge developmentally through a domain-general associative mechanism. We argue that experience-sensitivity does not rule out an adaptive or genetic argument for mirror neuron function, and that current evidence suggests that mirror neurons are more specialized than the authors' account would predict. We propose that future work integrate behavioral and neurophysiological techniques used with primates to examine the proposed functions of mirror neurons in action understanding.

Black Hole Thermodynamics and Lorentz Symmetry

NASA Astrophysics Data System (ADS)

Jacobson, Ted; Wall, Aron C.

2010-08-01

Recent developments point to a breakdown in the generalized second law of thermodynamics for theories with Lorentz symmetry violation. It appears possible to construct a perpetual motion machine of the second kind in such theories, using a black hole to catalyze the conversion of heat to work. Here we describe and extend the arguments leading to that conclusion. We suggest the inference that local Lorentz symmetry may be an emergent property of the macroscopic world with origins in a microscopic second law of causal horizon thermodynamics.

Profit maximization, industry structure, and competition: A critique of neoclassical theory

NASA Astrophysics Data System (ADS)

Keen, Steve; Standish, Russell

2006-10-01

Neoclassical economics has two theories of competition between profit-maximizing firms-Marshallian and Cournot-Nash-that start from different premises about the degree of strategic interaction between firms, yet reach the same result, that market price falls as the number of firms in an industry increases. The Marshallian argument is strictly false. We integrate the different premises, and establish that the optimal level of strategic interaction between competing firms is zero. Simulations support our analysis and reveal intriguing emergent behaviors.

Analytical investigation of the hygrothermal effects and parametric study of the Edge Crack Torsion (ECT) mode 3 test lay-ups

NASA Technical Reports Server (NTRS)

Li, Jian; Obrien, T. Kevin

1995-01-01

A shear deformation theory including residual thermal and moisture effects is developed for the analysis of either symmetric or unsymmetric laminates with mid-plane edge delamination under torsion loading. The theory is based on an assumed displacement field which includes shear deformation. The governing equations and boundary conditions are obtained from the principle of virtual work. The analysis of the (90/(+/- 45)(n)/(-/+ 45)(n)/90)(s) ECT mode 3 test lay-up indicates that there are no hygrothermal effects on the mode 3 strain energy release rate because the laminate, and both sublaminates above and below the delamination, are symmetric lay-ups. A further parametric study reveals that some other lay-ups can have negligible hygrothermal effects even when the sublaminates above and below the delamination are not symmetric about their own mid-planes. However, these lay-ups may suffer from distortion after the curing process. Another Interesting set of lay-ups investigated is a class of antisymmetric laminates with (+/-(theta/(theta -90)(2)/theta))(n) lay-ups. It is observed that when n takes on even numbers (2 and 4), both hygrothermal and mode 1 effects can be neglected. From this point of view, these lay-ups provide a way to determine the mode 3 toughness between two dissimilar layers. However, when n takes on odd numbers (1 and 3), both hygrothermal and mode 1 effects may be strong in these lay-ups. In particular, when theta equals 45 deg, the lay-ups are free from both hygrothermal and mode 1 effects irrespective of n.

Respecting Choices is an evidence-based model of facilitating advance care planning (ACP) conversations between health-care professionals and patients. However, the effectiveness of whether lay patient navigators can successfully initiate Respecting Choices ACP conversations is unknown. As part of a large demonstration project (Patient Care Connect [PCC]), a cohort of lay patient navigators underwent Respecting Choices training and were tasked to initiate ACP conversations with Medicare beneficiaries diagnosed with cancer. This article explores PCC lay navigators' perceived barriers and facilitators in initiating Respecting Choices ACP conversations with older patients with cancer in order to inform implementation enhancements to lay navigator-facilitated ACP. Twenty-six lay navigators from 11 PCC cancer centers in 4 states (Alabama, George, Tennessee, and Florida) completed in-depth, one-on-one semistructured interviews between June 2015 and August 2015. Data were analyzed using a thematic analysis approach. This evaluation identifies 3 levels-patient, lay navigator, and organizational factors in addition to training needs that influence ACP implementation. Key facilitators included physician buy-in, patient readiness, and navigators' prior experience with end-of-life decision-making. Lay navigators' perceived challenges to initiating ACP conversations included timing of the conversation and social and personal taboos about discussing dying. Our results suggest that further training and health system support are needed for lay navigators playing a vital role in improving the implementation of ACP among older patients with cancer. The lived expertise of lay navigators along with flexible longitudinal relationships with patients and caregivers may uniquely position this workforce to promote ACP.

This study aimed to determine the causal effect of the number of lay counselors employed at a primary care clinic in rural South Africa on the number of clinic-based HIV tests performed. Fixed effects panel analysis. We collected monthly data on the number of lay counselors employed and HIV tests performed at nine primary care clinics in rural KwaZulu-Natal from January 2014 to December 2015. Using clinic- and month-level fixed effects regressions, we exploited the fact that lay counselors were removed from clinics at two quasi-random time points by a redeployment policy. A total of 24,526 HIV tests were conducted over the study period. 21 of 27 lay counselors were removed across the nine clinics in the two redeployment waves. A ten percent reduction in the number of lay counselors was associated with a 4.9% (95% confidence interval [CI]: 2.8 - 7.0, p < 0.001) decrease in the number of HIV tests performed. In absolute terms, losing one lay counselor from a clinic was associated with a mean of 29.7 (95% CI: 21.2 - 38.2, p < 0.001) fewer HIV tests carried out at the clinic per month. This study provides evidence for the crucial role that lay counselors play in the HIV response in rural South Africa. More broadly, this analysis supports the use of lay cadres in the HIV response and by extension UNAIDS' and the African Union's goal to triple the number of community health workers in sub-Saharan Africa by 2020.

Appropriate emergency disaster preparedness is a key priority for agricultural agencies to allow effective response to serious avian disease outbreaks. There is a need to develop rapid, humane, and safe depopulation techniques for poultry that are widely applicable across a range of farm settings. Whole barn depopulation with carbon dioxide (CO(2)) has been investigated as a humane and efficient means of killing large numbers of birds in the event of a reportable disease outbreak. It has also been considered as a method for depopulating barns containing end-of-lay hens, particularly when there is limited local slaughter and rendering capacity. Determining the best method of humanely killing large flocks of birds remains problematic and is being investigated by a coordinated international effort. While whole barn depopulation using CO(2) inhalation has been explored, physiologic responses of chickens have not been characterized in field settings and assessment of animal welfare is hampered without this information. In this study, 12 cull laying hens were surgically instrumented with telemetry transmitters to record electroencephalographs, electrocardiographs, body temperature, and activity during 2 large-scale field CO(2) euthanasia trials of end-of-lay hens. The day following surgery, instrumented hens were placed in barns with other birds, barns were sealed, and animals were killed by CO(2) inhalation delivered via a specially designed liquid CO(2) manifold. Instrumented birds were monitored by infrared thermography, and ambient temperature, CO(2), and O(2) concentrations were recorded. Results from these studies indicate that instrumented hens lost consciousness within 2 min of CO(2) levels reaching 18 to 20%. Mild to moderate head shaking, gasping, and 1 to 2 clonic muscle contractions were noted in hens before unconsciousness; however, brain death followed rapidly (<5 min). Evaluation of welfare costs and benefits suggest clear advantages over catching and transporting cull hens for slaughter. The financial costs with this method are greater, however, than those estimated for traditional slaughter techniques. Results of these studies are being used to develop national protocols for whole barn depopulation of hens by CO(2) inhalation.

Lay perceptions of risk factors for Rift Valley fever in a pastoral community in northeastern Kenya.

2016-01-13

Human behavioral factors have been found to be central in the transmission of Rift Valley fever. Consumption of contaminated meat and milk in particular have been identified as one of the key risk factors for the transmission of Rift Valley fever in humans. In pastoral communities, livestock is the main source of livelihood from which many benefits such as food as well as economic and cultural services are derived. Zoonotic diseases therefore have a great impact on pastoral communities livelihoods. However, lay perceptions regarding the transmission of these diseases including Rift Valley fever hampers their effective control. This study investigated the lay perceptions of risks for Rift Valley fever transmission in a pastoral community in northeastern Kenya. A qualitative study was carried out in Ijara district, Kenya which was one of the hotspots of Rift Valley during the 2006/2007 outbreak. Data were collected using focus group discussions and narratives guided by checklists. Eight focus group discussions consisting of 83 participants and six narratives were conducted. Data was transcribed, coded and analysed according to Emergent themes. The participants reported that they had experienced Rift Valley fever in their livestock especially sheep and in humans both in 1997/1998 and 2006/2007. However, they believed that infections in humans occurred as a result of mosquito bites and had little to do with their consumption of meat, milk and blood from infected livestock. The participants in this study indicated that they had heard of the risks of acquiring the disease through consumption of livestock products but their experiences did not tally with the information they had received hence to them, Rift Valley fever was not transmissible through their dietary practices. Though the communities in this region were aware of Rift Valley fever, they did not have elaborate information regarding the disease transmission dynamics to humans. To avoid misconception about transmission of the disease, intervention strategies, require to be accompanied by comprehensive explanations of the dynamics of its transmission. It is necessary to develop appropriate interventions that take into consideration, lay perceptions of risk factors for the disease and communities' livelihood strategies.

Argumentation in elementary science education: addressing methodological issues and conceptual understanding

Kaya, Ebru

2017-11-01

In this review essay I respond to issues raised in Mijung Kim and Wolff-Michael Roth's paper titled "Dialogical argumentation in elementary science classrooms", which presents a study dealing with dialogical argumentation in early elementary school classrooms. Since there is very limited research on lower primary school students' argumentation in school science, their paper makes a contribution to research on children's argumentation skills. In this response, I focus on two main issues to extend the discussion in Kim and Roth's paper: (a) methodological issues including conducting a quantitative study on children's argumentation levels and focusing on children's written argumentation in addition to their dialogical argumentation, and (b) investigating children's conceptual understanding along with their argumentation levels. Kim and Roth emphasize the difficulty in determining the level of children's argumentation through the Toulmin's Argument Pattern and lack of high level arguments by children due to their difficulties in writing texts. Regarding these methodological issues, I suggest designing quantitative research on coding children's argument levels because such research could potentially provide important findings on children's argumentation. Furthermore, I discuss alternative written products including posters, figures, or pictures generated by children in order to trace children's arguments, and finally articulating argumentation and conceptual understanding of children.

Limited data exist about the role of the lay media in the dissemination of results of randomized controlled trials (RCTs) in common cancers. Completed phase III RCTs evaluating new drugs in common cancers between January 2005 and October 2016 were identified from ClinicalTrials.gov. Lay media reporting was identified by searching LexisNexis Academic. Scientific reporting was defined as presentation at an academic conference or publication in full. Associations between reporting in the lay media before scientific reporting and study design and sponsorship were evaluated using logistic regression. Of 180 RCTs identified, 52% were reported in the lay media and in 27%, lay media reporting occurred before scientific reporting with an increasing trend over time (p = 0.009). Reporting in the lay media before scientific reporting was associated with positive results (OR: 2.10, p = 0.04), targeted therapy compared to chemotherapy (OR: 4.75, p = 0.006), immunotherapy compared to chemotherapy (OR: 7.60, p = 0.02), and prostate cancer compared to breast cancer (OR: 3.25, p = 0.02). Over a quarter of all RCTs in common cancers are reported in the lay media before they are reported scientifically with an increasing proportion over time. Positive trials, studies in prostate cancer, and trials of immunotherapy are associated with early reporting in the lay media. © 2017 S. Karger AG, Basel.

Underground cable laying is an alternative for overhead cable laying of telecommunication and power transmission lines. It is becoming very popular in recent times because of some of its advantages over overhead cable laying. This type of cable laying is mostly practiced in developed countries because it is more expensive than overhead cable laying. Underground cable laying is more suitable when land is not available, and it also increases the aesthetics. This paper implements the automation on a manually operated cable pulling winch machine using programmable logic controller (PLC). Winch machines are useful in underground cable laying. The main aim of the project is to replace all the mechanical functions with electrical controls which are operated through a touch screen (HMI). The idea is that the machine should shift between parallel and series circuit automatically based on the pressure sensed instead of manually operating the solenoid valve. Traditional means of throttling the engine using lever and wire is replaced with a linear actuator. Sensors such as proximity, pressure and load sensor are used to provide the input to the system. The HMI used will display the speed, length and tension of the rope being winded. Ladder logic is used to program the PLC.

This study examined training outcomes for lay service providers who participated in a Motivational Interviewing (MI) training program designed to help increase intrinsic motivation and academic achievement among urban low-income and minority youth. Seventeen lay academic advisors received 16 hours of training in MI. Two, two-hour booster sessions plus five, two- hour weekly group supervision sessions were conducted with lay advisors over a period of seven months. One-hundred percent of lay advisors (n =17) participated in all training, booster sessions and assessments. Seventy-one percent of lay advisors (n=12) completed all group supervision sessions and submitted tapes for review. MI training was associated with increased knowledge of MI principles among lay service providers; increased proficiency in responding to simulated clients in an MI consistent style; increased use of MI adherent behaviors in sessions with real clients and maintenance of high motivation to use MI from pretest to posttest. Although lay advisors increased their knowledge of MI, further training is required for advisors to increase competence in delivering MI. Overall, Implications for using MI in the context of school-based settings is discussed. PMID:26356248

MI training was associated with increased knowledge of MI principles among lay service providers; increased proficiency in responding to simulated clients in an MI consistent style; increased use of MI adherent behaviors in sessions with real clients and maintenance of high motivation to use MI from pretest to posttest. Although lay advisors increased their knowledge of MI, further training is required for advisors to increase competence in delivering MI. Overall, Implications for using MI in the context of school-based settings is discussed.

Growing Fixed With Age: Lay Theories of Malleability Are Target Age-Specific.

PubMed

Neel, Rebecca; Lassetter, Bethany

2015-11-01

Beliefs about whether people can change ("lay theories" of malleability) are known to have wide-ranging effects on social motivation, cognition, and judgment. Yet rather than holding an overarching belief that people can or cannot change, perceivers may hold independent beliefs about whether different people are malleable-that is, lay theories may be target-specific. Seven studies demonstrate that lay theories are target-specific with respect to age: Perceivers hold distinct, uncorrelated lay theories of people at different ages, and younger targets are considered to be more malleable than older targets. Both forms of target-specificity are consequential, as target age-specific lay theories predict policy support for learning-based senior services and the rehabilitation of old and young drug users. The implications of target age-specific lay theories for a number of psychological processes, the social psychology of aging, and theoretical frameworks of malleability beliefs are discussed. © 2015 by the Society for Personality and Social Psychology, Inc.

Myths about autism: An exploratory study using focus groups.

Individuals with autism are often stigmatised and isolated by their typically developing peers according to parental, teacher and self-reports. While quantitative studies often report negative attitudes towards individuals with autism, it is still unclear how understandings of autism influence attitudes. In this exploratory study, misconceptions or myths about autism, that is, the cognitive component of attitudes, were examined using focus groups. Purposive sampling was used to recruit undergraduate and postgraduate students, and adults with and without experience of autism, to one of the five focus groups (n = 37). Content analysis was used to identify emergent themes. The data identified seven commonly held beliefs about individuals with autism. The first four were related to social interaction, such as that people with autism do not like to be touched. The fifth reflected the view that all individuals with autism have a special talent, and the final two concerned beliefs that people with autism are dangerous. The findings from this study demonstrate that people with varying experience or knowledge of autism often hold inaccurate beliefs about autism. These findings improve our understandings of lay beliefs about autism and will aid the development and implementation of interventions designed to improve lay knowledge of autism.

Lay Crowd-Sourced Expertise (LCE) and Its Influence on the New Role of Patients: Ethical and Societal Issues.

Lamas, Eugenia; Salinas, Rodrigo; Ferrer, Marcela; Bousquet, Cedric; Vuillaume, Dominique

2016-01-01

The emergence of social media on the Internet allows patients to discuss about their chronic diseases within online communities sharing common interests. This allows patients to gather other patients' experience, and gain new knowledge that is usually not shared by healthcare professionals. In this context, further studies are required on the actual impact of the use of social networks on the quality of life of patients participating in these online communities, focusing on the evolving role and impact of Lay Crowdsourced expertise (LCE) in improving disease management and control. We present a study on a large number of posts from social networks of different online communities. This study allowed us to choose four pathologies, with distinctive characteristics relevant for our future analysis, and to define the themes that will be covered in future work by online questionnaires. The analysis of responses from patients, who volunteer to participate, will help us in exploring how interactions between patients, on these online communities, may help them to gain useful information for managing their conditions and improving their quality of life. Furthermore, we will identify new ethical issues that arise in the sharing of health data.

Experiments were conducted on radiosterilization of male houseflies (Musca domestica). The females are monogamous, so that all the females mating with sterile males lay sterile eggs. Tests with 24-kv x rays showed that the most satisfactory method of sterilizing male houseflies consists of irradiating the pupa with 3000 r 2 to 3 days before emergence. The mortality of the irradiated pupae was not appreciably increased and the flies emerging from them were normal in appearance, viability, longevity, and sexual activity. When the irradiated males were mated with normal females, sterility was 100% complete. However, there was a slight tendency formore » females mated with irradiated males to remate with normal males. Sterile males successfully competed with normal males in search of females, and when they were present in overwhelming numbers succeeded in mating with most of the females, leaving them sterile.

Civilian helicopters and emergency medical services in the United States have been in existence for approximately 15 years. The rapid growth of this type of health care delivery coupled with an increasing number of accidents has prompted professional and lay scrutiny of these programs. Although they have a demonstrated history of benefit to patients, the type and severity of injuries to patients who are eligible for helicopter transportation need further definition. The composition of the medical crews and the benefits that particular crew members bring to the patients require ongoing evaluation. Significant questions regarding the number of pilots in a helicopter and in a program remain to be answered. This article reviews the role of emergency medical air transport services in providing care to trauma patients, staff training and evaluation, and safety criteria and offers recommendations to minimize risks to patients and crews.

There is a spurt of interest in research productivity in the Gulf Cooperation Council (GCC) to lay the foundation for national development. From a global perspective, increased research productivity could conceivably be accompanied by an exponential increase in research misconduct (RM). Inevitably, erroneous or falsified data will be expected to adversely affect public health by misleading policy makers and clinicians alike into embarking on health policy and allocation of resources that are byproducts of RM. This will contribute significantly to the emerging crisis of confidence of the public in the integrity of scientific research. For a long time, RM has been considered only as plagiarism or data fabrication and falsification. However, the concept of RM nowadays encompasses more and, in this review, we discuss its possible implications in emerging economies, such as those of the GCC countries. We suggest that GCC countries ought to consider implementing remedial and punitive policies to deal with RM. PMID:26816563

Bacterial Overgrowth and Irritable Bowel Syndrome: Unifying Hypothesis or a Spurious Consequence of Proton Pump Inhibitors?

PubMed Central

Spiegel, Brennan M.R.; Chey, William D.; Chang, Lin

2010-01-01

Some studies indicate that small intestinal bacterial overgrowth (SIBO), as measured by hydrogen breath tests (HBT), is more prevalent in patients with irritable bowel syndrome (IBS) vs. matched controls without IBS. Although the data are conflicting, this observation has led to the hypothesis that SIBO may be a primary cause of IBS. Yet, it remains unclear whether SIBO is truly fundamental to the pathophysiology of IBS, or is instead a mere epiphenomenon or bystander of something else altogether. We hypothesize that SIBO might be a byproduct of the disproportionate use of proton pump inhibitors (PPIs) in IBS, as follows: (1) IBS patients are more likely than controls to receive PPI therapy; (2) PPI therapy may promote varying forms of SIBO by eliminating gastric acid; and (3) existing studies linking SIBO to IBS have not adjusted for or excluded the use of PPI therapy. When linked together, these premises form the basis for a simple and testable hypothesis: the relationship between SIBO and IBS may be confounded by PPIs. Our article explores these premises, lays out the argument supporting this “PPI hypothesis,” discusses potential implications, and outlines next steps to further investigate this possibility.

Active euthanasia in pre-modern society, 1500-1800: learned debates and popular practices.

PubMed

Stolberg, Michael

2007-08-01

Historians of medical ethics have found that active euthanasia, in the sense of intentionally hastening the death of terminally-ill patients, was considered unacceptable in the Christian West before the 1870s. This paper presents a range of early modern texts on the issue which reflect a learned awareness of practices designed to shorten the lives of dying patients which were widely accepted among the lay public. Depriving the dying abruptly of their head-rest or placing them flat on the cold floor may strike us as merely symbolic today, but early moderns associated such measures with very concrete and immediate effects. In this sense, the intentional hastening of death in agonising patients had an accepted place in pre-modern popular culture. These practices must, however, be put into their proper context. Death was perceived more as a transition to the after-life and contemporary notions of dying could make even outright suffocation appear as an act of compassion which merely helped the soul depart from the body at the divinely ordained hour of death. The paper concludes with a brief comparison of early modern arguments with those of today.

Superfluous neuroscience information makes explanations of psychological phenomena more appealing.

Fernandez-Duque, Diego; Evans, Jessica; Christian, Colton; Hodges, Sara D

2015-05-01

Does the presence of irrelevant neuroscience information make explanations of psychological phenomena more appealing? Do fMRI pictures further increase that allure? To help answer these questions, 385 college students in four experiments read brief descriptions of psychological phenomena, each one accompanied by an explanation of varying quality (good vs. circular) and followed by superfluous information of various types. Ancillary measures assessed participants' analytical thinking, beliefs on dualism and free will, and admiration for different sciences. In Experiment 1, superfluous neuroscience information increased the judged quality of the argument for both good and bad explanations, whereas accompanying fMRI pictures had no impact above and beyond the neuroscience text, suggesting a bias that is conceptual rather than pictorial. Superfluous neuroscience information was more alluring than social science information (Experiment 2) and more alluring than information from prestigious "hard sciences" (Experiments 3 and 4). Analytical thinking did not protect against the neuroscience bias, nor did a belief in dualism or free will. We conclude that the "allure of neuroscience" bias is conceptual, specific to neuroscience, and not easily accounted for by the prestige of the discipline. It may stem from the lay belief that the brain is the best explanans for mental phenomena.

The legislation of active voluntary euthanasia in Australia: will the slippery slope prove fatal?

1996-01-01

At 2.00 am on the morning of May 24, 1995 the Northern Territory Legislative Assembly Australia passed the Rights of the Terminally Ill Act by the narrow margin of 15 votes to 10. The act permits a terminally ill patient of sound mind and over the age of 18 years, and who is either in pain or suffering, or distress, to request a medical practitioner to assist the patient to terminate his or her life. Thus, Australia can lay claim to being the first country in the world to legalise voluntary active euthanasia. The Northern Territory's act has prompted Australia-wide community reaction, particularly in South Australia, Tasmania and the Australian Capital Territory where proposals to legalise euthanasia have already been defeated on the floor of parliament. In New South Wales (NSW) the AIDS Council of NSW has prepared draft euthanasia legislation to be introduced into the Upper House as a Private Member's Bill some time in 1996. In this paper, we focus on a brief description of events as they occurred and on the arguments for and against the legalisation of euthanasia which have appeared in the media. PMID:8910778

Over the past several years, John Hamaker and a number of followers have put forth a hypothesis that the imminent demise of the world's forests from lack of vital mineral nutrients will trigger an ice age. Their evidence in support of this hypothesis has recently appeared as a videotape entitled ''Stopping the Coming Ice Age.'' These comments were prepared in response to the arguments presented on this tape, which several people have suggested presents a highly important scientific analysis unfairly receiving too little attention. I will focus primarily on analysis of the climatic aspects of the Hamaker hypothesis. The videotapemore » attempts to put forth a coherent and appealing story, but does so by taking comments of some scientists out of context, by quoting some scientists out of their field of expertise, by skimming over some serious shortcomings, by facile assumptions not easily spotted by the non-specialist, and by mixing in many true statements (which makes it especially difficult for the lay listener to spot the problems). Overall, these actions combine to make the presentation of the hypothesis very appealing, but also very deceptive.« less

Deconstructing design: a strategy for defending science.

PubMed

Miller, K R

2009-01-01

Despite its legal and scientific failings, the "intelligent design" (ID) movement has been a public relations success story in the United States. By first creating doubts about the adequacy of evolution to account for the complexity of life, the ID movement has invoked the values of "fairness" and "openness" to argue for inclusion in the classroom and curriculum. In this way, it has attempted to lay claim to the very principles of critical analysis and open discussion at the heart of the scientific enterprise, leaving many researchers in doubt as to how to respond to these challenges. Specific case studies, including the blood-clotting cascade and data from the human genome, show how scientists can have a leading role in deconstructing the arguments advanced in favor of ID. The key to this strategy is remarkably simple and was at the heart of the landmark 2005 Kitzmiller v. Dover trial on ID. It is for researchers to take the claims made by ID proponents seriously, and then to follow them to their logical scientific conclusions. When this is done effectively, the hypothesis of "design" can be publicly falsified in ways that are understandable to laypeople and decision makers in education.

In an earlier essay in this journal I critiqued Don Marquis's well-known argument against abortion. I distinguished two versions of Marquis's argument, which I refer to as 'the essence argument' and 'the sufficient condition argument'. I presented two counterexamples showing that the essence argument was mistaken, and I argued that the sufficient condition argument should be rejected because Marquis had not adequately responded to an important objection to it. In response to my critique, Marquis put forward in this journal a revised version of his argument. In his modified approach he no longer advocates the essence argument and he offers a new version of the sufficient condition argument. In the current essay, I discuss how Marquis's revised argument deals with my original objections, and I argue that his new sufficient condition argument is unsuccessful.

Urolithiasis presenting as right flank pain: a case report.

PubMed

Chung, Chadwick; Stern, Paula J; Dufton, John

2013-03-01

Urolithiasis refers to renal or ureteral calculi referred to in lay terminology as a kidney stone. Utolithiasis is a potential emergency often resulting in acute abdominal, low back, flank or groin pain. Chiropractors may encounter patients when they are in acute pain or after they have recovered from the acute phase and should be knowledgeable about the signs, symptoms, potential complications and appropriate recommendations for management. A 52 year old male with acute right flank pain presented to the emergency department. A ureteric calculus with associated hydronephrosis was identified and he was prescribed pain medications and discharged to pass the stone naturally. One day later, he returned to the emergency department with severe pain and was referred to urology. He was managed with a temporary ureteric stent and antibiotics. This case describes a patient with acute right flank and lower quadrant pain which was diagnosed as an obstructing ureteric calculus. Acute management and preventive strategies in patients with visceral pathology such as renal calculi must be considered in patients with severe back and flank pain as it can progress to hydronephrosis and kidney failure.

Understanding a High School Physics Teacher's Pedagogical Content Knowledge of Argumentation

NASA Astrophysics Data System (ADS)

Wang, Jianlan; Buck, Gayle A.

2016-08-01

Scientific argumentation is an important learning objective in science education. It is also an effective instructional approach to constructivist science learning. The implementation of argumentation in school settings requires science teachers, who are pivotal agents of transforming classroom practices, to develop sophisticated knowledge of argumentation. However, there is a lack of understanding about science teachers' knowledge of argumentation, especially the dialogic meaning of argumentation. In this case study, we closely examine a high school physics teacher's argumentation-related pedagogic content knowledge (PCK) in the context of dialogic argumentation. We synthesize the teacher's performed PCK from his argumentation practices and narrated PCK from his reflection on the argumentation practices, from which we summarize his PCK of argumentation from the perspectives of orientation, instructional strategies, students, curriculum, and assessment. Finally, we describe the teacher's perception and adaption of argumentation in his class. We also identity the barriers to argumentation implementation in this particular case and suggest solutions to overcome these barriers.

Ergonomics and sustainability: towards an embrace of complexity and emergence.

PubMed

Dekker, Sidney W A; Hancock, Peter A; Wilkin, Peter

2013-01-01

Technology offers a promising route to a sustainable future, and ergonomics can serve a vital role. The argument of this article is that the lasting success of sustainability initiatives in ergonomics hinges on an examination of ergonomics' own epistemology and ethics. The epistemology of ergonomics is fundamentally empiricist and positivist. This places practical constraints on its ability to address important issues such as sustainability, emergence and complexity. The implicit ethical position of ergonomics is one of neutrality, and its positivist epistemology generally puts value-laden questions outside the parameters of what it sees as scientific practice. We argue, by contrast, that a discipline that deals with both technology and human beings cannot avoid engaging with questions of complexity and emergence and seeking innovative ways of addressing these issues. Ergonomics has largely modelled its research on a reductive science, studying parts and problems to fix. In sustainability efforts, this can lead to mere local adaptations with a negative effect on global sustainability. Ergonomics must consider quality of life globally, appreciating complexity and emergent effects of local relationships.

Measuring Resilience.

Hoffman, Robert R; Hancock, P A

2017-06-01

As human factors and ergonomics (HF/E) moves to embrace a greater systems perspective concerning human-machine technologies, new and emergent properties, such as resilience, have arisen. Our objective here is to promote discussion as to how to measure this latter, complex phenomenon. Resilience is now a much-referenced goal for technology and work system design. It subsumes the new movement of resilience engineering. As part of a broader systems approach to HF/E, this concept requires both a definitive specification and an associated measurement methodology. Such an effort epitomizes our present work. Using rational analytic and synthetic methods, we offer an approach to the measurement of resilience capacity. We explicate how our proposed approach can be employed to compare resilience across multiple systems and domains, and emphasize avenues for its future development and validation. Emerging concerns for the promise and potential of resilience and associated concepts, such as adaptability, are highlighted. Arguments skeptical of these emerging dimensions must be met with quantitative answers; we advance one approach here. Robust and validated measures of resilience will enable coherent and rational discussions of complex emergent properties in macrocognitive system science.

Practice and perception of first aid among lay first responders in a southern district of India.

Injuries rank among the leading causes of morbidity and mortality worldwide, and are steadily increasing in developing countries like India. However, it is often possible to minimize injury and crash consequences by providing effective pre-hospital services promptly. In most low-and middle-income countries (LMICs), transportation of road traffic victims, is usually provided by relatives, taxi drivers, truck drivers, police officers and other motorists who are often untrained. The current study was conducted to understand the current practice and perception of first aid among lay first responders in a rural southern district of India. The current cross sectional descriptive study was conducted in the southern district of Tumkur in India within three months from January to March 2011 and covered the population including all police, ambulance personnel, taxi drivers, bus and auto drivers, and primary and middle school teachers within the study area. Nearly 60% of the responders had witnessed more than two emergencies in the previous six months and 55% had actively participated in helping the injured person. The nature of the help was mainly by calling for an ambulance (41.5%), transporting the injured (19.7%) and consoling the victim (14.9%). Majority (78.1%) of the responders informed that they had run to the victim (42.4%) or had called for an ambulance. The predominant reason for not providing help was often the 'fear of legal complications' (30%) that would follow later. Significant number (81.4%) of respondents reported that they did not have adequate skills to manage an emergency and were willing to acquire knowledge and skills in first aid to help victims. Regular and periodical community-based first aid training programs for first care responders will help to provide care and improve outcomes for injured persons.

Despite the many recent improvements in basic life support (BLS) and the widespread training to a great number of lay rescuers, out-of-hospital cardiac arrest (OHCA) is still a major cause of death. Nowadays, BLS teaching protocols ask for many concepts to be learned and specific algorithms to be applied, without any available data on how much all these inputs are retained by the students. The present survey aims to evaluate how BLS is really retained by those rescuers (laypersons and nurses) who do not often put it into practice. The first survey was targeted at laypersons who are responsible for security in their work environment. The second survey was targeted at nurses operating in low-intensity wards or out-of-hospital clinics. Both surveys were anonymous and asked specific questions aimed at evaluating how BLS/BLS-D (BLS and defibrillation) information was retained on an average of 3 years after training completion. Lay rescuers showed difficulties in recognizing specific signs of OHCA, were unsure on when to call the emergency medical service and retained few and sometime erroneous information on the correct BLS sequence to perform. The nurses operating in low-intensity settings performed better in terms of OHCA recognition and advanced medical assistance activation, while how to set and operate an automatic external defibrillation was seldom clear. BLS information is usually not retained after a 3-year follow-up by people who are not involved in OHCA management as part of their everyday job. It should be useful to lower the number of concepts taught in current BLS courses in order to focus on the most significant aspects of it, such as prompt emergency medical system activation and early defibrillation.

Diagnostic Categories in Autobiographical Accounts of Illness.

Kelly, Michael P

2015-01-01

Working within frameworks drawn from the writings of Immanuel Kant, Alfred Schutz, and Kenneth Burke, this article examines the role that diagnostic categories play in autobiographical accounts of illness, with a special focus on chronic disease. Four lay diagnostic categories, each with different connections to formal medical diagnostic categories, serve as typifications to make sense of the way the lifeworld changes over the course of chronic illness. These diagnostic categories are used in conjunction with another set of typifications: lay epidemiologies, lay etiologies, lay prognostics, and lay therapeutics. Together these serve to construct and reconstruct the self at the center of the lifeworld. Embedded within the lay diagnostic categories are narratives of progression, regression, or stability, forms of typification derived from literary and storytelling genres. These narratives are developed by the self in autobiographical accounts of illness.

Lay health advisers: scoping the role and intervention landscape.

Carr, Susan M; Lhussier, Monique; Forster, Natalie

2017-01-01

The use of lay health advisers has become an established approach within public health, in particular for impact on health inequalities and engaging socially excluded groups. Evidence on how differences in terms of the multiple role dimensions impact the outcomes of programs is limited. This creates ambiguity for decision makers on which roles should be implemented in different contexts for different needs. This paper applies realist logic to an inquiry to explore the mechanisms that may operate in lay-led intervention models and understand how, why, and in what respect these lead to particular outcomes. It draws on a project focusing on health-related lifestyle advisers and further insights gained from a subsequent related project about outreach with traveler communities. Analysis highlights multiple and potentially interacting aspects of lay health-adviser roles that may influence their success, including characteristics of lay health advisers, characteristics of target populations, purpose or intent of interventions, and how advice is given. A model is proposed from which to examine the contexts and mechanisms of lay health advisers that may impact outcomes, and is subsequently applied to two examples of reported lay health-adviser interventions. The combination of skills and characteristics of lay health advisers must be considered when planning which interventions might be appropriate when targeting specific needs or target populations. Focus only on the peer/layperson distinction may overlook other potentially important skills and mechanisms of action integral to lay health-adviser roles.

The locating ways of laying pipe manipulator

The laying pipe manipulator is a new equipment to lay concrete pipe. This kind of manipulator makes the work of laying pipes mechanized and automated. We report here a new laying pipe manipulator. The manipulator has 5 free degrees, and is driven by the hydraulic system. In the paper, one critical question of manipulator is studied: the locating ways of the manipulator to lay concrete pipe. During the process of laying concrete pipe, how to locate the manipulator is realized by the locating system of manipulator. The locating system consists of photoelectric target, laser producer, and computer. According to different construction condition, one or two or three photoelectric targets can be used. During the process of laying concrete pipe, if the interface of pipes are jointed together, and the other segment of pipe deviates from the pipe way, one target can be used, if the angle that the manipulator rotates around the holding pipe's axes is 0°, two targets can be used, three targets can be used at any site. In the paper, according to each locating way, the theory analysis is done. And the mathematical models of the manipulator moving from original position to goal position are obtained by different locating way. And the locating experiment was done. According to the experiment result, the work principle and mathematical models of different locating way was turned out to be well adopted for requirement, the mathematical model of different locating way supplies the basic control theory for the manipulator to lay and joint concrete pipe automatically.

Interpretive analysis of 85 systematic reviews suggests that narrative syntheses and meta-analyses are incommensurate in argumentation.

Using Toulmin's argumentation theory, we analysed the texts of systematic reviews in the area of workplace health promotion to explore differences in the modes of reasoning embedded in reports of narrative synthesis as compared with reports of meta-analysis. We used framework synthesis, grounded theory and cross-case analysis methods to analyse 85 systematic reviews addressing intervention effectiveness in workplace health promotion. Two core categories, or 'modes of reasoning', emerged to frame the contrast between narrative synthesis and meta-analysis: practical-configurational reasoning in narrative synthesis ('what is going on here? What picture emerges?') and inferential-predictive reasoning in meta-analysis ('does it work, and how well? Will it work again?'). Modes of reasoning examined quality and consistency of the included evidence differently. Meta-analyses clearly distinguished between warrant and claim, whereas narrative syntheses often presented joint warrant-claims. Narrative syntheses and meta-analyses represent different modes of reasoning. Systematic reviewers are likely to be addressing research questions in different ways with each method. It is important to consider narrative synthesis in its own right as a method and to develop specific quality criteria and understandings of how it is carried out, not merely as a complement to, or second-best option for, meta-analysis. © 2016 The Authors.

Laying-sequence-specific variation in yolk oestrogen levels, and relationship to plasma oestrogen in female zebra finches (Taeniopygia guttata)

We investigated the relationship between plasma and yolk oestrogens in laying female zebra finches (Taeniopygia guttata) by manipulating plasma oestradiol (E2) levels, via injection of oestradiol-17β, in a sequence-specific manner to maintain chronically high plasma levels for later-developing eggs (contrasting with the endogenous pattern of decreasing plasma E2 concentrations during laying). We report systematic variation in yolk oestrogen concentrations, in relation to laying sequence, similar to that widely reported for androgenic steroids. In sham-manipulated females, yolk E2 concentrations decreased with laying sequence. However, in E2-treated females plasma E2 levels were higher during the period of rapid yolk development of later-laid eggs, compared with control females. As a consequence, we reversed the laying-sequence-specific pattern of yolk E2: in E2-treated females, yolk E2 concentrations increased with laying-sequence. In general therefore, yolk E2 levels were a direct reflection of plasma E2 levels. However, in control females there was some inter-individual variability in the endogenous pattern of plasma E2 levels through the laying cycle which could generate variation in sequence-specific patterns of yolk hormone levels even if these primarily reflect circulating steroid levels.

Birnessite, a phyllomanganate and the most common type of Mn oxide, affects the fate and transport of numerous contaminants and nutrients in nature. Birnessite exhibits hexagonal (HexLayBir) or orthogonal (OrthLayBir) layer symmetry. The two types of birnessite contain contrasting content of layer vacancies and Mn(III), and accordingly have different sorption and oxidation abilities. OrthLayBir can transform to HexLayBir, but it is still vaguely understood if and how the reverse transformation occurs. Here, we show that HexLayBir (e.g., δ-MnO2 and acid birnessite) transforms to OrthLayBir after reaction with aqueous Mn(II) at low Mn(II)/Mn (in HexLayBir) molar ratios (5-24%) and pH ≥ 8. The transformation is promoted by higher pH values, as well as smaller particle size, and/or greater stacking disorder of HexLayBir. The transformation is ascribed to Mn(III) formation via the comproportionation reaction between Mn(II) adsorbed on vacant sites and the surrounding layer Mn(IV), and the subsequent migration of the Mn(III) into the vacancies with an ordered distribution in the birnessite layers. This study indicates that aqueous Mn(II) and pH are critical environmental factors controlling birnessite layer structure and reactivity in the environment.

Artifacts, intentions, and contraceptives: the problem with having a plan B for plan B.

PubMed

Reed, Philip A

2013-12-01

It is commonly proposed that artifacts cannot be understood without reference to human intentions. This fact, I contend, has relevance to the use of artifacts in intentional action. I argue that because artifacts have intentions embedded into them antecedently, when we use artifacts we are sometimes compelled to intend descriptions of our actions that we might, for various reasons, be inclined to believe that we do not intend. I focus this argument to a specific set of artifacts, namely, medical devices, before considering an extended application to emergency contraceptive devices. Although there is some debate about whether emergency contraception has an abortifacient effect, I argue that if there is an abortifacient effect, then the effect cannot normally be a side effect of one's action.

Ethics and biobanks

PubMed Central

Hansson, M G

2008-01-01

Biobank research has been the focus of great interest of scholars and regulatory bodies who have addressed different ethical issues. On the basis of a review of the literature it may be concluded that, regarding some major themes in this discussion, a consensus seems to emerge on the international scene after the regular exchange of arguments in scientific journals. Broad or general consent is emerging as the generally preferred solution for biobank studies and straightforward instructions for coding will optimise privacy while facilitating research that may result in new methods for the prevention of disease and for medical treatment. The difficult question regarding the return of information to research subjects is the focus of the current research, but a helpful analysis of some of the issues at stake and concrete recommendations have recently been suggested.

The Global Solar Dynamo

NASA Astrophysics Data System (ADS)

Cameron, R. H.; Dikpati, M.; Brandenburg, A.

2017-09-01

A brief summary of the various observations and constraints that underlie solar dynamo research are presented. The arguments that indicate that the solar dynamo is an alpha-omega dynamo of the Babcock-Leighton type are then shortly reviewed. The main open questions that remain are concerned with the subsurface dynamics, including why sunspots emerge at preferred latitudes as seen in the familiar butterfly wings, why the cycle is about 11 years long, and why the sunspot groups emerge tilted with respect to the equator (Joy's law). Next, we turn to magnetic helicity, whose conservation property has been identified with the decline of large-scale magnetic fields found in direct numerical simulations at large magnetic Reynolds numbers. However, magnetic helicity fluxes through the solar surface can alleviate this problem and connect theory with observations, as will be discussed.

Lay theories of smoking and young adult nonsmokers' and smokers' smoking expectations.

PubMed

Fitz, Caroline C; Kaufman, Annette; Moore, Philip J

2015-04-01

This study investigated the relationship between lay theories of cigarette smoking and expectations to smoke. An incremental lay theory of smoking entails the belief that smoking behavior can change; an entity theory entails the belief that smoking behavior cannot change. Undergraduate nonsmokers and smokers completed a survey that assessed lay theories of smoking and smoking expectations. Results demonstrated that lay theories of smoking were differentially associated with smoking expectations for nonsmokers and smokers: stronger incremental beliefs were associated with greater expectations of trying smoking for nonsmokers but lower expectations of becoming a regular smoker for smokers. Implications for interventions are discussed. © The Author(s) 2013.

This study investigated the changes of nutrient compositions of piled laying hen manure, detected the physical and chemical components of laying hen manure fermented by mixed strains, and analysed its application effects on feeding ruminants. The results showed that with increasing of piling time, the contents of crude protein (CP) and ether extract (EE) in laying hen manure were reduced, while the contents of crude ash (CA), calcium (Ca) and phosphorus (P) were increased. Fermentation could effectively decrease pH value, reduce Ca/P ratio, lessen the total bacterial counts, and maintain the organisms contents in laying hen manure. The results of ruminants feeding test indicated that replacing 20% diet with laying hen manure fermentation products (MFP), the weight gain and reproductive rate were respectively decreased by 9.99% and 2% compared with the control group, and the differences were not statistically significant. This technology could recycle laying hen manures as ruminant feeds, for the purpose of reducing environmental pollution and improving economic efficiency. Copyright © 2017 Elsevier Ltd.

Religion and bioethics.

PubMed

Holm, Soren

2004-01-01

This paper discusses the role of religious arguments in public bioethical debate. It is argued that attempts to rule out religious arguments as valid contributions to the pubic debate fails for a number of reasons. There is no non-arbitrary way of dividing religious arguments from non-religious arguments, and all arguments refer ultimately to a background comprehensive worldview that is never fully consistent or coherent and which is furthermore always contested. There are thus no good arguments for treating religious arguments differently than any other type of argument.

Argumentation is a crucial component of our lives. Although in the absence of rational debate our legal, political, and scientific systems would not be possible, there is still no integrated area of research on the psychology of argumentation. Furthermore, classical theories of argumentation are normative (i.e., the acceptability of an argument is determined by a set of norms or logical rules), which sometimes creates a dissociation between the theories and people’s behavior. We think the current challenge for psychology is to bring together the cognitive and normative accounts of argumentation. In this article, we exemplify this point by analyzing two cases of argumentative structures experimentally studied in the context of cognitive psychology. Specifically, we focus on the slippery slope argument and the ad hominem argument under the frameworks of Bayesian and pragma-dialectics approaches, respectively. We think employing more descriptive and experimental accounts of argumentation would help Psychology to bring closer the cognitive and normative accounts of argumentation with the final goal of establishing an integrated area of research on the psychology of argumentation.

Evaluating science arguments: evidence, uncertainty, and argument strength.

PubMed

Corner, Adam; Hahn, Ulrike

2009-09-01

Public debates about socioscientific issues are increasingly prevalent, but the public response to messages about, for example, climate change, does not always seem to match the seriousness of the problem identified by scientists. Is there anything unique about appeals based on scientific evidence-do people evaluate science and nonscience arguments differently? In an attempt to apply a systematic framework to people's evaluation of science arguments, the authors draw on the Bayesian approach to informal argumentation. The Bayesian approach permits questions about how people evaluate science arguments to be posed and comparisons to be made between the evaluation of science and nonscience arguments. In an experiment involving three separate argument evaluation tasks, the authors investigated whether people's evaluations of science and nonscience arguments differed in any meaningful way. Although some differences were observed in the relative strength of science and nonscience arguments, the evaluation of science arguments was determined by the same factors as nonscience arguments. Our results suggest that science communicators wishing to construct a successful appeal can make use of the Bayesian framework to distinguish strong and weak arguments. 2009 APA, all rights reserved

Examining Elementary Students' Development of Oral and Written Argumentation Practices Through Argument-Based Inquiry

Chen, Ying-Chih; Hand, Brian; Park, Soonhye

2016-05-01

Argumentation, and the production of scientific arguments are critical elements of inquiry that are necessary for helping students become scientifically literate through engaging them in constructing and critiquing ideas. This case study employed a mixed methods research design to examine the development in 5th grade students' practices of oral and written argumentation from one unit to another over 16 weeks utilizing the science writing heuristic approach. Data sources included five rounds of whole-class discussion focused on group presentations of arguments that occurred over eleven class periods; students' group writings; interviews with six target students and the teacher; and the researcher's field notes. The results revealed five salient trends in students' development of oral and written argumentative practices over time: (1) Students came to use more critique components as they participated in more rounds of whole-class discussion focused on group presentations of arguments; (2) by challenging each other's arguments, students came to focus on the coherence of the argument and the quality of evidence; (3) students came to use evidence to defend, support, and reject arguments; (4) the quality of students' writing continuously improved over time; and (5) students connected oral argument skills to written argument skills as they had opportunities to revise their writing after debating and developed awareness of the usefulness of critique from peers. Given the development in oral argumentative practices and the quality of written arguments over time, this study indicates that students' development of oral and written argumentative practices is positively related to each other. This study suggests that argumentative practices should be framed through both a social and epistemic understanding of argument-utilizing talk and writing as vehicles to create norms of these complex practices.

BRCA Gist is an Intelligent Tutoring System that helps women understand issues related to genetic testing and breast cancer risk. In two laboratory experiments and a field experiment with community and web-based samples, an avatar asked 120 participants to produce arguments for and against genetic testing for breast cancer risk. Two raters assessed the number of argumentation elements (claim, reason, backing, etc.) found in response to prompts soliciting arguments for and against genetic testing for breast cancer risk (IRR=.85). When asked to argue for genetic testing, 53.3 % failed to meet the minimum operational definition of making an argument, a claim supported by one or more reasons. When asked to argue against genetic testing, 59.3 % failed to do so. Of those who failed to generate arguments most simply listed disconnected reasons. However, participants who provided arguments against testing (40.7 %) performed significantly higher on a posttest of declarative knowledge. In each study we found positive correlations between the quality of arguments against genetic testing (i.e., number of argumentation elements) and genetic risk categorization scores. Although most interactions did not contain two or more argument elements, when more elements of arguments were included in the argument against genetic testing interaction, participants had greater learning outcomes. Apparently, many participants lack skills in making coherent arguments. These results suggest an association between argumentation ability (knowing how to make complex arguments) and subsequent learning. Better education in developing arguments may be necessary for people to learn from generating arguments within Intelligent Tutoring Systems and other settings.

Lay health advisor activity levels: definitions from the field.

PubMed

Altpeter, M; Earp, J A; Bishop, C; Eng, E

1999-08-01

One type of lay health advisor model assumes that an effective mechanism for reaching the underserved is through informal advice-givers called natural helpers. Despite the growing use of this approach, few programs have defined what an active lay health advisor does within the natural helping process. To explore perceptions and definitions of lay health advisors' activity, we conducted semistructured, in-person interviews with four field staff who coordinate the advisors' activities in a breast cancer screening program. These staff viewed lay health advisor activity as fluctuating over the course of a year, occurring along a continuum of participation (inactive, moderately active, active, and superactive), and reflecting varying degrees of proactivity and participation in multiple activities. These results suggest an empirical process for refining the definition of an active lay health advisor, improving advisors' productivity in achieving outreach objectives, and managing and monitoring their ongoing activities.

This paper recounts experiences, challenges, and lessons learned when implementing a lay patient navigator program to improve cancer care among medically underserved patients who presented in a primary care clinic with a breast or colorectal cancer abnormality. The program employed five lay navigators to navigate 588 patients. Central programmatic elements were: 1) use of bilingual lay navigators with familiarity of communities they served; 2) provision of training, education and supportive activities; 3) multidisciplinary clinical oversight that factored in caseload intensity; and 4) well-developed partnerships with community clinics and social service entities. Deconstruction of health care system information was fundamental to navigation processes. We conclude that a lay model of navigation is well suited to assist patients through complex health care systems; however, a stepped care model that includes both lay and professional navigation may be optimal to help patients across the entire continuum.

Modelling Scientific Argumentation in the Classroom : Teachers perception and practice

Probosari, R. M.; Sajidan; Suranto; Prayitno, B. A.; Widyastuti, F.

2017-02-01

The purposes of this study were to investigate teacher’s perception about scientific argumentation and how they practice it in their classroom. Thirty biology teachers in high school participated in this study and illustrated their perception of scientific argumentation through a questionnaire. This survey research was developed to measure teachers’ understanding of scientific argumentation, what they know about scientific argumentation, the differentiation between argument and reasoning, how they plan teaching strategies in order to make students’ scientific argumentation better and the obstacles in teaching scientific argumentation. The result conclude that generally, teachers modified various representation to accommodate student’s active participation, but most of them assume that argument and reasoning are similar. Less motivation, tools and limited science’s knowledge were considered as obstacles in teaching argumentation. The findings can be helpful to improving students’ abilities of doing scientific argumentation as a part of inquiry.

Evaluating arguments during instigations of defence motivation and accuracy motivation.

Liu, Cheng-Hong

2017-05-01

When people evaluate the strength of an argument, their motivations are likely to influence the evaluation. However, few studies have specifically investigated the influences of motivational factors on argument evaluation. This study examined the effects of defence and accuracy motivations on argument evaluation. According to the compatibility between the advocated positions of arguments and participants' prior beliefs and the objective strength of arguments, participants evaluated four types of arguments: compatible-strong, compatible-weak, incompatible-strong, and incompatible-weak arguments. Experiment 1 revealed that participants possessing a high defence motivation rated compatible-weak arguments as stronger and incompatible-strong ones as weaker than participants possessing a low defence motivation. However, the strength ratings between the high and low defence groups regarding both compatible-strong and incompatible-weak arguments were similar. Experiment 2 revealed that when participants possessed a high accuracy motivation, they rated compatible-weak arguments as weaker and incompatible-strong ones as stronger than when they possessed a low accuracy motivation. However, participants' ratings on both compatible-strong and incompatible-weak arguments were similar when comparing high and low accuracy conditions. The results suggest that defence and accuracy motivations are two major motives influencing argument evaluation. However, they primarily influence the evaluation results for compatible-weak and incompatible-strong arguments, but not for compatible-strong and incompatible-weak arguments. © 2016 The British Psychological Society.

Origins of life and biochemistry under high-pressure conditions.

PubMed

Daniel, Isabelle; Oger, Philippe; Winter, Roland

2006-10-01

Life on Earth can be traced back to as far as 3.8 billion years (Ga) ago. The catastrophic meteoritic bombardment ended between 4.2 and 3.9 Ga ago. Therefore, if life emerged, and we know it did, it must have emerged from nothingness in less than 400 million years. The most recent scenarios of Earth accretion predict some very unstable physico-chemical conditions at the surface of Earth, which, in such a short time period, would impede the emergence of life from a proto-biotic soup. A possible alternative would be that life originated in the depth of the proto-ocean of the Hadean Earth, under high hydrostatic pressure. The large body of water would filter harmful radiation and buffer physico-chemical variations, and therefore would provide a more stable radiation-free environment for pre-biotic chemistry. After a short introduction to Earth history, the current tutorial review presents biological and physico-chemical arguments in support of high-pressure origin for life on Earth.

The Emergence of Relationship-based Cooperation.

PubMed

Xu, Bo; Wang, Jianwei

2015-11-16

This paper investigates the emergence of relationship-based cooperation by coupling two simple mechanisms into the model: tie strength based investment preference and homophily assumption. We construct the model by categorizing game participants into four types: prosocialists (players who prefers to invest in their intimate friends), antisocialists (players who prefer to invest in strangers), egoists (players who never cooperate) and altruists (players who cooperate indifferently with anyone). We show that the relationship-based cooperation (prosocialists) is favored throughout the evolution if we assume players of the same type have stronger ties than different ones. Moreover, we discover that strengthening the internal bonds within the strategic clusters further promotes the competitiveness of prosocialists and therefore facilitates the emergence of relationship-based cooperation in our proposed scenarios. The robustness of the model is also tested under different strategy updating rules and network structures. The results show that this argument is robust against the variations of initial conditions and therefore can be considered as a fundamental theoretical framework to study relationship-based cooperation in reality.

A revolution of the mind: some implications of George Hogenson's 'The Baldwin Effect: a neglected influence on C.G. Jung's evolutionary thinking' (2001).

PubMed

Colman, Warren

2015-09-01

George Hogenson's 2001 paper 'The Baldwin Effect: a neglected influence on C.G. Jung's evolutionary thinking' developed the radical argument that, if archetypes are emergent, they 'do not exist in the sense that there is no place that the archetypes can be said to be'. In this paper, I show how Hogenson's thinking has been seminal to my own: it is not just archetypes but the mind itself that has no 'place'. The mind is a dynamic system, emergent from the cultural environment of symbolic meanings to which humans are evolutionarily adapted. Drawing on the work of philosopher John Searle, I argue that symbols constitute the realities that they bring forth, including the imaginal realities of the psyche. The implications for clinical work include a rejection of structural models of the psyche in favour of the emergence of symbolic realities in the context of psychoanalysis as a distributed system of cognition. © 2015, The Society of Analytical Psychology.

Transnational tobacco company (TTC) submissions to the 2012 UK standardised packaging consultation are studied to examine TTC argumentation in the context of Better Regulation practices. A content analysis was conducted of Philip Morris International and British American Tobacco submissions to the 2012 UK consultation. Industry arguments concerning expected costs and (contested) benefits of the policy were categorised into themes and frames. The inter-relationship between frames through linked arguments was mapped to analyse central arguments using an argumentation network. 173 arguments were identified. Arguments fell into one of five frames: ineffectiveness, negative economic consequences, harm to public health, increased crime or legal ramifications. Arguments highlighted high costs to a wide range of groups, including government, general public and other businesses. Arguments also questioned the public health benefits of standardised packaging and highlighted the potential benefits to undeserving groups. An increase in illicit trade was the most central argument and linked to the greatest variety of arguments. In policy-making systems characterised by mandatory impact assessments and public consultations, the wide range of cost (and contested benefits) based arguments highlights the risk of TTCs overloading policy actors and causing delays in policy adoption. Illicit trade related arguments are central to providing a rationale for these arguments, which include the claim that standardised packaging will increase health risks. The strategic importance of illicit trade arguments to industry argumentation in public consultations underlines the risks of relying on industry data relating to the scale of the illicit trade. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

Cryoethics: seeking life after death.

PubMed

Shaw, David

2009-11-01

Cryonic suspension is a relatively new technology that offers those who can afford it the chance to be 'frozen' for future revival when they reach the ends of their lives. This paper will examine the ethical status of this technology and whether its use can be justified. Among the arguments against using this technology are: it is 'against nature', and would change the very concept of death; no friends or family of the 'freezee' will be left alive when he is revived; the considerable expense involved for the freezee and the future society that will revive him; the environmental cost of maintaining suspension; those who wish to use cryonics might not live life to the full because they would economize in order to afford suspension; and cryonics could lead to premature euthanasia in order to maximize chances of success. Furthermore, science might not advance enough to ever permit revival, and reanimation might not take place due to socio-political or catastrophic reasons. Arguments advanced by proponents of cryonics include: the potential benefit to society; the ability to cheat death for at least a few more years; the prospect of immortality if revival is successful; and all the associated benefits that delaying or avoiding dying would bring. It emerges that it might be imprudent not to use the technology, given the relatively minor expense involved and the potential payoff. An adapted and more persuasive version of Pascal's Wager is presented and offered as a conclusive argument in favour of utilizing cryonic suspension.

Factors impacting teachers' argumentation instruction in their science classrooms

McNeill, Katherine L.; Katsh-Singer, Rebecca; González-Howard, María; Loper, Suzanna

2016-08-01

Science education research, reform documents and standards include scientific argumentation as a key learning goal for students. The role of the teacher is essential for implementing argumentation in part because their beliefs about argumentation can impact whether and how this science practice is integrated into their classroom. In this study, we surveyed 42 middle school science teachers and conducted follow-up interviews with 25 to investigate the factors that teachers believe impact their argumentation instruction. Teachers responded that their own learning goals had the greatest impact on their argumentation instruction while influences related to context, policy and assessment had the least impact. The minor influence of policy and assessment was in part because teachers saw a lack of alignment between these areas and the goals of argumentation. In addition, although teachers indicated that argumentation was an important learning goal, regardless of students' backgrounds and abilities, the teachers discussed argumentation in different ways. Consequently, it may be more important to help teachers understand what counts as argumentation, rather than provide a rationale for including argumentation in instruction. Finally, the act of trying out argumentation in their own classrooms, supported through resources such as curriculum, can increase teachers' confidence in teaching argumentation.

A growing body of scholarship has evaluated the usefulness of meaning-based theories in the context of bereavement counseling. Although scholars have discussed the application of meaning-based theories for individual practice, there is a lack of inquiry regarding its implications when conducting bereavement support groups. The objective of this article is to bridge meaning-based theories with bereavement group practice, leading to a novel intervention and laying the foundation for future efficacy studies. Building on recommendations specified in the literature, this article outlines the theoretical paradigms and structure of a short-term meaning-based group counseling intervention for uncomplicated bereavement.

Magnetic carbon nanotubes (MCNTs) have been widely studied for their potential applications in medicine, diagnosis, cell biology, analytical chemistry, and environmental technology. Introduction of MCNTs paved the way for the emergence of new approaches in nanobiotechnology and biomedicine as a result of their multifarious properties embedded within either the carbon nanotubes (CNTs) or magnetic parts. Numerous preparation techniques exists for functionalizing CNTs with magnetic nanoparticles, and these versatile strategies lay the ground for the generation of novel and versatile systems which are applicable to many industries and biological areas. Here, we review and discuss the recent papers dealing with MCNTs and their application in biomedical and industrial fields.

An Argumentation Framework based on Paraconsistent Logic

NASA Astrophysics Data System (ADS)

Umeda, Yuichi; Takahashi, Takehisa; Sawamura, Hajime

Argumentation is the most representative of intelligent activities of humans. Therefore, it is natural to think that it could have many implications for artificial intelligence and computer science as well. Specifically, argumentation may be considered a most primitive capability for interaction among computational agents. In this paper we present an argumentation framework based on the four-valued paraconsistent logic. Tolerance and acceptance of inconsistency that this logic has as its logical feature allow for arguments on inconsistent knowledge bases with which we are often confronted. We introduce various concepts for argumentation, such as arguments, attack relations, argument justification, preferential criteria of arguments based on social norms, and so on, in a way proper to the four-valued paraconsistent logic. Then, we provide the fixpoint semantics and dialectical proof theory for our argumentation framework. We also give the proofs of the soundness and completeness.

Early Onset of Laying and Bumblefoot Favor Keel Bone Fractures

Simple Summary Numerous studies have documented a high prevalence of keel bone fractures in laying hens. In this longitudinal study, 80 white and brown laying hens were regularly checked for keel bone deviations and fractures while egg production was individually monitored. About 62% of the hens had broken keel bones at depopulation. More new fractures occurred during the time when laying rates were highest. Hens with broken keel bones at depopulation had laid their first egg earlier than hens with intact keel bones. All birds with bumblefoot on both feet had a fracture at depopulation. Abstract Numerous studies have demonstrated influences of hybrid, feed, and housing on prevalence of keel bone fractures, but influences of behavior and production on an individual level are less known. In this longitudinal study, 80 white and brown laying hens were regularly checked for keel bone deviations and fractures while egg production was individually monitored using Radio Frequency Identification (RFID) from production until depopulation at 65 weeks of age. These focal birds were kept in eight pens with 20 hens per pen in total. About 62% of the hens had broken keel bones at depopulation. The occurrence of new fractures was temporally linked to egg laying: more new fractures occurred during the time when laying rates were highest. Hens with fractured keel bones at depopulation had laid their first egg earlier than hens with intact keel bones. However, the total number of eggs was neither correlated with the onset of egg laying nor with keel bone fractures. All birds with bumblefoot on both feet had a fracture at depopulation. Hens stayed in the nest for a longer time during egg laying during the ten days after the fracture than during the ten days before the fracture. In conclusion, a relationship between laying rates and keel bone fractures seems likely. PMID:26633520

Diabetes self-management education: acceptability of using trained lay educators.

2014-11-01

The use of lay people to deliver education programmes for people with chronic conditions is a potential method of addressing healthcare staff capacity and increasing the cost efficiency of delivering education. This qualitative substudy is embedded within an equivalence trial (2008-2011 including development stage). In the qualitative substudy, we aimed to elicit the views of key stakeholders (patients, educators) about using lay people to deliver education to people recently diagnosed with type 2 diabetes, alongside a healthcare professional educator with an equal role. In this way, we sought to explore perceptions about acceptability and also contribute to understanding the reasons underlying positive or negative quantitative findings from main trial. We conducted 27 telephone interviews with a purposive sample of patients, lay educators and healthcare professional educators involved in the main trial. Thematic analysis of transcribed data was underpinned by the constant comparative approach and structured using Framework methodology. Overall, the data suggested that the use of lay educators was acceptable to educators and patients. Perceived difference in knowledge levels between lay and healthcare professional educators did not appear to have an impact on perceived acceptability or the effectiveness of the education received. Additional themes explored were related to peer status of educators and feasibility. Some concerns were raised about lay educators with diabetes, transferring personal issues and about the impact of healthcare professional time taken up by mentoring and supporting lay educators. Positive perceptions about the use of lay educators support the positive quantitative findings from the main trial. Acceptability is an important consideration in relation to implementation of the model of delivery studied. Concerns raised within the interviews should be considered in the design of training for lay educators. ISRCTN 99350009. Published by the BMJ Publishing Group Limited.

2017-01-04

Only an estimated 54% of people living with HIV are aware of their status. Despite progress scaling up HIV testing services (HTS), a testing gap remains. Delivery of HTS by lay providers may help close this testing gap, while also increasing uptake and acceptability of HIV testing among key populations and other priority groups. 50 National HIV testing policies were collated from WHO country intelligence databases, contacts and testing program websites. Data regarding lay provider use for HTS was extracted and collated. Our search had no geographical or language restrictions. This data was then compared with reported data from the Global AIDS Response Progress Reporting (GARPR) from July 2015. Forty-two percent of countries permit lay providers to perform HIV testing and 56% permit lay providers to administer pre-and post-test counseling. Comparative analysis with GARPR found that less than half (46%) of reported data from countries were consistent with their corresponding national HIV testing policy. Given the low uptake of lay provider use globally and their proven use in increasing HIV testing, countries should consider revising policies to support lay provider testing using rapid diagnostic tests.

Comparative proteomic analysis of pituitary glands from Huoyan geese between pre-laying and laying periods using an iTRAQ-based approach

2017-01-01

In this study, we performed a comprehensive evaluation of the proteomic profile of the pituitary gland of the Huoyan goose during the laying period compared to the pre-laying period using an iTRAQ-based approach. Protein samples were prepared from pituitary gland tissues of nine pre-laying period and nine laying period geese. Then the protein samples from three randomly selected geese within each period were pooled in equal amounts to generate one biological sample pool. We identified 684 differentially expressed proteins, including 418 up-regulated and 266 down-regulated proteins. GO annotation and KEGG pathway analyses of these proteins were conducted. Some of these proteins were found to be associated with hormone and neurotransmitter secretion and transport, neuropeptide signalling and GnRH signalling pathways, among others. Subsequently, the modification of the abundance of three proteins (prolactin, chromogranin-A and ITPR3) was verified using western blotting. Our results will provide a new source for mining genes and gene products related to the egg-laying performance of Huoyan geese, and may provide important information for the conservation and utilization of local goose breeds.

To investigate the effect of chromium picolinate (CrPic) on egg production performance, egg quality, blood indices, and immune function of laying hens, 270 23-week-old Beijing Red brown-egg laying hens were randomly assigned to one of three treatments with six replicates of 15 birds per replicate for each treatment in a completely randomized design. Laying hens were fed a Cr-unsupplemented corn-soybean meal basal diet (control, containing 0.45 mg Cr/kg by analysis) or the basal diet supplemented with 0.4 or 0.6 mg Cr/kg from CrPic for 10 weeks. Laying hens fed diets supplemented with CrPic had a lower (P < 0.05) serum glucose (GLU) concentration and higher (P < 0.03) serum antibody titer against Newcastle disease than those fed the control diet at 33 weeks of age. However, supplemental CrPic had no effect (P > 0.05) on egg production and egg quality of brown-egg laying hens from 24 to 33 weeks of age. The results from this study indicated that supplemental CrPic decreased serum GLU and enhanced the immune function of brown-egg laying hens.

The Selective Laziness of Reasoning.

PubMed

Trouche, Emmanuel; Johansson, Petter; Hall, Lars; Mercier, Hugo

2016-11-01

Reasoning research suggests that people use more stringent criteria when they evaluate others' arguments than when they produce arguments themselves. To demonstrate this "selective laziness," we used a choice blindness manipulation. In two experiments, participants had to produce a series of arguments in response to reasoning problems, and they were then asked to evaluate other people's arguments about the same problems. Unknown to the participants, in one of the trials, they were presented with their own argument as if it was someone else's. Among those participants who accepted the manipulation and thus thought they were evaluating someone else's argument, more than half (56% and 58%) rejected the arguments that were in fact their own. Moreover, participants were more likely to reject their own arguments for invalid than for valid answers. This demonstrates that people are more critical of other people's arguments than of their own, without being overly critical: They are better able to tell valid from invalid arguments when the arguments are someone else's rather than their own.

Responding to Public Health Emergencies on Tribal Lands: Jurisdictional Challenges and Practical Solutions.

PubMed

Barnard, Justin B

2015-01-01

Response to public health emergencies on tribal lands poses a unique challenge for state and tribal public health officials. The complexity and intensely situation-specific nature of federal Indian jurisprudence leaves considerable question as to which government entity, state or tribal, has jurisdiction on tribal lands to undertake basic emergency measures such as closure of public spaces, quarantine, compulsory medical examination, and investigation. That jurisdictional uncertainty, coupled with cultural differences and an often troubled history of tribal-state relations, threatens to significantly impede response to infectious disease outbreaks or other public health emergencies on tribal lands. Given that tribal communities may be disproportionately impacted by public health emergencies, it is critical that tribal, state, and local governments engage with each other in coordinated planning for public health threats. This Article is offered as a catalyst for such planning efforts. The Article identifies some of the most pressing jurisdictional issues that may confront governments responding to a public health emergency on tribal lands, with the aim of highlighting the nature of the problem and the need for action. The Article goes on to examine the most promising means of addressing jurisdictional uncertainty: intergovernmental agreements. Already utilized in many areas of shared interest between tribe and state, intergovernmental agreements offer neighboring state, local, and tribal governments a vehicle for delineating roles and authorities in an emergency, and may lay the groundwork for sharing resources. The Article surveys various representative tribal public health intergovernmental agreements, and concludes with suggestions for tribes and state or local governments looking to craft their own agreements.

Practitioner and lay perspectives of the service provision of nutrition information leaflets in primary care.

2011-12-01

In primary care, leaflets are often used to communicate health information. Increasingly, primary healthcare practitioners need to provide dietary advice. There is limited research exploring how nutrition information leaflets are used in primary care. The present study explored practitioner and lay experiences with respect to providing and receiving nutrition information in primary care, focusing in particular on the use of leaflets for nutrition information. A qualitative design was used incorporating focus groups with 57 practitioners based at seven general practitioner practices and a purposive sample of 30 lay participants attending six Consumer Health Organisations within one primary care trust. Focus groups were taped and transcribed verbatim and data were analysed thematically, assisted by computer software n6® (QSR International Pty Ltd, Melbourne, Australia). Practitioners discussed barriers to giving nutritional advice, access to leaflets, lay receptiveness to advice and their perceptions about the value of leaflets to lay people. Food was not considered in terms of its nutritional components by lay participants and the need for nutritional information was not perceived to be relevant until they had received a medical diagnosis. Lay participants discussed the importance of receiving nutritional advice relating to their medical diagnosis and the altered status of written information that was delivered personally. Practitioner and lay groups suggested improvements to ensure that nutritional advice be supported by relevant and appropriate written information. This research has underlined the continuing importance of nutrition information leaflets and concludes that there is particular value in involving lay participants in the development of nutrition information leaflets. © 2011 The Authors.

Failed landings after laying hen flight in a commercial aviary over two flock cycles.

PubMed

Campbell, D L M; Goodwin, S L; Makagon, M M; Swanson, J C; Siegford, J M

2016-01-01

Many egg producers are adopting alternative housing systems such as aviaries that provide hens a tiered cage and a litter-covered open floor area. This larger, more complex environment permits expression of behaviors not seen in space-limited cages, such as flight. Flight is an exercise important for strengthening bones; but domestic hens might display imperfect flight landings due to poor flight control. To assess the potential implications of open space, we evaluated the landing success of Lohmann white laying hens in a commercial aviary. Video recordings of hens were taken from 4 aviary sections at peak lay, mid lay and end lay across two flock cycles. Observations were made in each focal section of all flights throughout the day noting flight origin and landing location (outer perch or litter) and landing success or failure. In Flock 1, 9.1% of all flights failed and 21% failed in Flock 2. The number of flights decreased across the laying cycle for both flocks. Proportionally more failed landings were observed in the double row sections in Flock 2. Collisions with other hens were more common than slipping on the ground or colliding with aviary structures across sections and flocks. More hens slipped on the ground and collided with physical structures at peak lay for Flock 2 than at other time points. More collisions with other hens were seen at mid and end lay than at peak lay for Flock 2. Landings ending on perches failed more often than landings on litter. These results indicate potential for flight-related hen injuries in aviary systems resulting from failed landings, which may have implications for hen welfare and optimal system design and management.

Perch use by laying hens in a commercial aviary1

Campbell, D. L. M.; Makagon, M. M.; Swanson, J. C.; Siegford, J. M.

2016-01-01

Non-cage housing systems, such as the aviary, are being implemented by the laying hen industry, including in North America, in an attempt to improve the welfare of hens. Perches are a resource that is consistently included in aviaries. Hens are strongly motivated to perch, and perching can improve leg bone strength. However, hens may prefer elevated perches, particularly at night, and thus simply providing perches is not enough to improve welfare; they must be provided in a way that allows all hens to access them. Observations of laying hens using perches and ledges (flat, solid metal shelves to assist hens’ movement between tiers) in a commercial aviary revealed variation in where hens roosted within the tiered aviary enclosure across the flock cycle (peak, mid and end of lay; P < 0.001 for all age points). Hens most often preferred roosting in the highest enclosure levels, leading to crowding on upper perches and ledges while perch space remained available on lower levels. Restricted access to preferable perches may cause frustration in hens, leading to welfare issues. Hens roosted more on perches at peak lay than mid and end lay (P < 0.001) but roosted less on ledges at peak lay than mid and end lay (P < 0.001). Additionally, more hens roosted on both perches and ledges in the ‘dark’ observation period compared with the number of hens roosting during the ‘light’ observation period (P < 0.001). Further research should look at all structural elements within the system that are used by hens for roosting, such as edges of tiers and upper wire floors, to evaluate how changes in perching preferences across the lay cycle may correlate with system design and bird-based parameters.

What's the Worst that Could Happen: A Veteran of the Climate Change Culture Wars Explains Why America Isn't Listening, and What to Do About It

NASA Astrophysics Data System (ADS)

Craven, G. A.

2010-12-01

In the Spring of 2007, high school science teacher Greg Craven posted a ten-minute whiteboard lecture on YouTube titled "The Most Terrifying Video You'll Ever See," in which he used a 2 x 2 grid to explore the relative risks of acting or not acting on climate change. Significantly, the conclusion he reached--that significant action should be taken immediately--did not rely on the actual science of climate change at all. Three years later, that video has been viewed over 8 million times, with no campaign, no money, and no organization--just the giving of the video's URL to Craven's 150 students on the last day of school. This example of the viral spread of a message through the Internet demonstrates the breathtaking speed with which the Power of One can act in the digital age. Spurred by criticisms of his argument (which Craven had invited, in the spirit of science), Craven spent several months reading tens of thousands of comments about his video, searching for every possible objection and counterargument that he could find. He eventually responded with a 7-hour series of videos on YouTube, updating the argument and addressing the criticisms. In the process, he became something of an expert in what--and how--the average American thinks about climate change. Craven then wrote the book "What's the Worst That Could Happen? A Rational Response to the Climate Change Debate," in which he proposes a process for the average lay person to use in order to decide the issue for themselves, without needing to decide which side in the debate to believe. The book is aimed squarely at the great unengaged majority--where the battle for action on climate change will ultimately be won or lost--in order to break their decision paralysis as they are overwhelmed with arguments from both sides of the debate. In this session, Craven will briefly share the grid of the original video that resonated with so many people, and will discuss the insights he's gained from debating online with the general public about climate change, as well as his proposed decision-making process that evolved as a result. He will also make suggestions about what scientists, both as professionals and as individual citizens, can do to communicate with the general public on the topic of climate change.

Patterns in Students' Argumentation Confronted with a Risk-focused Socio-scientific Issue

Kolstø, Stein Dankert

2006-11-01

This paper reports a qualitative study on students’ informal reasoning on a controversial socio-scientific issue. Twenty-two students from four science classes in Norway were interviewed about the local construction of new power lines and the possible increased risk of childhood leukaemia. The focus in the study is on what arguments the students employ when asked about their decision-making and the interplay between knowledge and personal values. Five different types of main arguments are identified: the relative risk argument, the precautionary argument, the uncertainty argument, the small risk argument, and the pros and cons argument. These arguments are presented through case studies, and crucial information and values are identified for each argument. The students made use of a range of both scientific and non-scientific knowledge. The findings are discussed in relation to possible consequences for teaching models aimed at increasing students’ ability to make thoughtful decisions on socio-scientific issues.

This study investigated how the instruction of argumentation skills could be promoted by using an online argumentation system. This system entitled `Cognitive Apprenticeship Web-based Argumentation' (CAWA) system was based on cognitive apprenticeship model. One hundred eighty-nine fifth grade students took part in this study. A quasi-experimental design was adopted and qualitative and quantitative analyses were used to evaluate the effectiveness of this online system in measuring students' progress in learning argumentation. The results of this study showed that different teaching strategies had effects on students' use of argumentation in the topics of daily life and the concept of `vision.' When the CAWA system was employed during the instruction and practice of argumentation on these two topics, the students' argumentation performance improved. Suggestions on how the CAWA system could be used to enhance the instruction of argumentation skills in science education were also discussed.

A Lay Ethics Quest for Technological Futures: About Tradition, Narrative and Decision-Making.

PubMed

van der Burg, Simone

2016-01-01

Making better choices about future technologies that are being researched or developed is an important motivator behind lay ethics interventions. However, in practice, they do not always succeed to serve that goal. Especially authors who have noted that lay ethicists sometimes take recourse to well-known themes which stem from old, even 'archetypical' stories, have been criticized for making too little room for agency and decision-making in their approach. This paper aims to contribute to a reflection on how lay ethics can acquire more practical relevance. It will use resources in narrative ethics to suggest that in order to be relevant for action, facilitators of lay ethics interventions need to invite participants to engage in a narrative quest. As part of a quest, lay ethicists should be asked to (1) reflect on a specific question or choice, (2) use diverse (imaginative) input which is informative about the heterogeneity of viewpoints that are defended in society and (3) argue for their standpoints.

Experimental and analytical study of high velocity impact on Kevlar/Epoxy composite plates

2012-12-01

In the present study, impact behavior of Kevlar/Epoxy composite plates has been carried out experimentally by considering different thicknesses and lay-up sequences and compared with analytical results. The effect of thickness, lay-up sequence on energy absorbing capacity has been studied for high velocity impact. Four lay-up sequences and four thickness values have been considered. Initial velocities and residual velocities are measured experimentally to calculate the energy absorbing capacity of laminates. Residual velocity of projectile and energy absorbed by laminates are calculated analytically. The results obtained from analytical study are found to be in good agreement with experimental results. It is observed from the study that 0/90 lay-up sequence is most effective for impact resistance. Delamination area is maximum on the back side of the plate for all thickness values and lay-up sequences. The delamination area on the back is maximum for 0/90/45/-45 laminates compared to other lay-up sequences.

The turn to the local: the possibility of returning health care to the community.

PubMed

Newton, Lisa H

2002-10-01

It is not too early to suggest that the attempts to place medical cae in private hands (through group insurance arrangements) has not fulfilled its promise--or better, the promises that were made for it. Yet history has not been kind to plans to make government the single payer, and the laudable progress in medical technology has placed high-technology medical care beyond the reach of most private budgets. In this paper I suggest that the major problem of the U.S. health care system as presently conceived is a failure of legitimacy, and I put forward a proposal that purports to solve that problem. The proposal is to localize health care, on the model of a public school system, on the argument that such localization will answer most of the questions of legitimacy at the core of the private insurance imbroglio, provide a brake for medical costs, while preserving our ability to take advantage of the most advanced medical interventions. I present some initial arguments for the proposal, but await its proof in the dialogue emerging as the present insurance system collapses.

The (sexual) politics of evolution: popular controversy in the late 20th-century United Kingdom.

PubMed

Cassidy, Angela

2007-05-01

This article outlines the major threads of controversy around the emerging subject of evolutionary psychology in the U.K. mass media during the 1990s. Much of this controversy centered on the role of evolution in shaping human gender roles and sexualities, contributing to the subject's mass appeal. This case is used to illustrate the argument that in theorizing about evolution and humans, "human nature" and "human origins" both provide a flexible resource for making arguments about how people do and should relate to one another and that such theorizing is therefore reflective of how power is held (and contested) in society. In the case of popular evolutionary psychology, shifts in the U.K. political landscape during the 1990s combined with changes in gender and sexual politics to create a situation where evolutionary theorizing about humans became more acceptable than it had been in the past. This was particularly true in left-liberal media, where a newfound compatibility between certain aspects of Darwinism and feminism created a very different space for debating gender, sexuality, and the role of human nature in today's society.

Physician Dismissal of Families Who Refuse Vaccination: An Ethical Assessment.

PubMed

Diekema, Douglas S

2015-01-01

Thousands of U.S. parents choose to refuse or delay the administration of selected vaccines to their children each year, and some choose not to vaccinate their children at all. While most physicians continue to provide care to these families over time, using each visit as an opportunity to educate and encourage vaccination, an increasing number of physicians are choosing to dismiss these families from their practice unless they agree to vaccinate their children. This paper will examine this emerging trend along with the reasons given by those who advocate such an approach. I will argue that the strategy of refusing to allow families into a clinic unless they agree to vaccinate their children is misguided, and the arguments for doing so fail to stand up to close scrutiny. Such a strategy does not benefit the child or the health of the community, and may have a negative impact on both. Furthermore, some of the arguments in support of dismissal policies ignore the importance of professional obligation and appear to favor self-interest over the interest of the patient. © 2015 American Society of Law, Medicine & Ethics, Inc.

Is the local linearity of space-time inherited from the linearity of probabilities?

NASA Astrophysics Data System (ADS)

Müller, Markus P.; Carrozza, Sylvain; Höhn, Philipp A.

2017-02-01

The appearance of linear spaces, describing physical quantities by vectors and tensors, is ubiquitous in all of physics, from classical mechanics to the modern notion of local Lorentz invariance. However, as natural as this seems to the physicist, most computer scientists would argue that something like a ‘local linear tangent space’ is not very typical and in fact a quite surprising property of any conceivable world or algorithm. In this paper, we take the perspective of the computer scientist seriously, and ask whether there could be any inherently information-theoretic reason to expect this notion of linearity to appear in physics. We give a series of simple arguments, spanning quantum information theory, group representation theory, and renormalization in quantum gravity, that supports a surprising thesis: namely, that the local linearity of space-time might ultimately be a consequence of the linearity of probabilities. While our arguments involve a fair amount of speculation, they have the virtue of being independent of any detailed assumptions on quantum gravity, and they are in harmony with several independent recent ideas on emergent space-time in high-energy physics.

Darwin and the linguists: the coevolution of mind and language, part 2. The language-thought relationship.

PubMed

Alter, Stephen G

2008-03-01

This paper examines Charles Darwin's idea that language-use and humanity's unique cognitive abilities reinforced each other's evolutionary emergence-an idea Darwin sketched in his early notebooks, set forth in his Descent of man (1871), and qualified in Descent's second (1874) edition. Darwin understood this coevolution process in essentially Lockean terms, based on John Locke's hints about the way language shapes thinking itself. Ironically, the linguist Friedrich Max Müller attacked Darwin's human descent theory by invoking a similar thesis, the German romantic notion of an identity between language and thought. Although Darwin avoided outright contradiction, when he came to defend himself against Müller's attacks, he undercut some of his own argumentation in favor of the coevolution idea. That is, he found it difficult to counter Müller's argument while also making a case for coevolution. Darwin's efforts in this area were further complicated by British and American writers who held a naturalistic view of speech origins yet still taught that language had been invented by fully evolved homo sapiens, thus denying coevolution.

This review article aims to discuss and analyze the background and findings regarding Fisher-Mendel Controversy in Genetics and to elucidate the scientific argument and intellectual integrity involved, as well as their importance in a fair society, and the lesson of Western falls as learned. At the onset of this review, the kernel of Mendel-Fisher Controversy is dissected and then identified. The fact of an organizational restructuring that had never gone towards a happy synchronization for the ensuing years since 1933 is demonstrated. It was at that time after Fisher succeeded Karl Pearson not only as the Francis Galton Professor of Eugenics but also as the chief of the Galton Laboratory at University College, London. The academic style of eugenics in the late 19th and early 20th centuries in the UK is then introduced. Fisher's ideology at that time, with its effects on the human value system and policy-making at that juncture are portrayed. Bioethical assessment is provided. Lessons in history, the emergence of the Eastern phenomenon and the decline of the Western power are outlined.

For the law, neuroscience changes nothing and everything.

The rapidly growing field of cognitive neuroscience holds the promise of explaining the operations of the mind in terms of the physical operations of the brain. Some suggest that our emerging understanding of the physical causes of human (mis)behaviour will have a transformative effect on the law. Others argue that new neuroscience will provide only new details and that existing legal doctrine can accommodate whatever new information neuroscience will provide. We argue that neuroscience will probably have a transformative effect on the law, despite the fact that existing legal doctrine can, in principle, accommodate whatever neuroscience will tell us. New neuroscience will change the law, not by undermining its current assumptions, but by transforming people's moral intuitions about free will and responsibility. This change in moral outlook will result not from the discovery of crucial new facts or clever new arguments, but from a new appreciation of old arguments, bolstered by vivid new illustrations provided by cognitive neuroscience. We foresee, and recommend, a shift away from punishment aimed at retribution in favour of a more progressive, consequentialist approach to the criminal law. PMID:15590618

The purpose of this research was to identify student's written argument embedded in scientific inqury investigation and argumentation skill using integrated argument-based inquiry with multiple representation approach. This research was using quasi experimental method with the nonequivalent pretest-posttest control group design. Sample ot this research was 10th grade students at one of High School in Bandung using two classes, they were 26 students of experiment class and 26 students of control class. Experiment class using integrated argument-based inquiry with multiple representation approach, while control class using argument-based inquiry. This study was using argumentation worksheet and argumentation test. Argumentation worksheet encouraged students to formulate research questions, design experiment, observe experiment and explain the data as evidence, construct claim, warrant, embedded multiple modus representation and reflection. Argumentation testinclude problem which asks students to explain evidence, warrants, and backings support of each claim. The result of this research show experiment class students's argumentation skill performed better than control class students that of experiment class was 0.47 and control class was 0.31. The results of unequal variance t-test for independent means show that students'sargumentationskill of experiment class performed better significantly than students'sargumentationskill of control class.

TAPping into argumentation: Developments in the application of Toulmin's Argument Pattern for studying science discourse

2004-11-01

This paper reports some methodological approaches to the analysis of argumentation discourse developed as part of the two-and-a-half year project titled Enhancing the Quality of Argument in School Scienc'' supported by the Economic and Social Research Council in the United Kingdom. In this project researchers collaborated with middle-school science teachers to develop models of instructional activities in an effort to make argumentation a component of instruction. We begin the paper with a brief theoretical justification for why we consider argumentation to be of significance to science education. We then contextualize the use of Toulmin's Argument Pattern in the study of argumentation discourse and provide a justification for the methodological outcomes our approach generates. We illustrate how our work refines and develops research methodologies in argumentation analysis. In particular, we present two methodological approaches to the analysis of argumentation resulting in whole-class as well as small-group student discussions. For each approach, we illustrate our coding scheme and some results as well as how our methodological approach has enabled our inquiry into the quality of argumentation in the classroom. We conclude with some implications for future research in argumentation in science education.

Analysis of scientific argumentation in two physical chemistry classrooms using the POGIL approach

NASA Astrophysics Data System (ADS)

Moon, Alena C.

The benefits of facilitating argumentation in science education have been well reported (Jimenez-Aleixandre & Erduran, 2007). Engaging in argumentation has shown to model authentic scientific inquiry as well as promote development of content knowledge. However, less emphasis has been placed on facilitating argumentation in upper level undergraduate courses, though it is important for evaluating undergraduate curricula to characterize upper level students' scientific reasoning. This work considers two implementations of the POGIL physical chemistry curriculum and evaluates the classroom argumentation. The researchers aimed to consider the content of the arguments and dialectical features characteristic of socially constructed arguments (Nielson, 2013). To do this, whole class sessions were videotaped and Toulmin's Argument Pattern (TAP) was used to identify the arguments generated during the class (Erduran, Simon, & Osborne, 2004). A learning progression on chemical thinking (Sevian & Talanquer, 2014) was used as a domain-specific measure of argument quality. Results show differences in argumentation between and across both classrooms that can be explained by analysis of instructor facilitation and the POGIL curriculum. The results from this work will be used to make recommendations for instructor facilitation of argumentation and reform of the POGIL curriculum.

Using Computer-Assisted Argumentation Mapping to develop effective argumentation skills in high school advanced placement physics

NASA Astrophysics Data System (ADS)

Heglund, Brian

Educators recognize the importance of reasoning ability for development of critical thinking skills, conceptual change, metacognition, and participation in 21st century society. There is a recognized need for students to improve their skills of argumentation, however, argumentation is not explicitly taught outside logic and philosophy---subjects that are not part of the K-12 curriculum. One potential way of supporting the development of argumentation skills in the K-12 context is through incorporating Computer-Assisted Argument Mapping to evaluate arguments. This quasi-experimental study tested the effects of such argument mapping software and was informed by the following two research questions: 1. To what extent does the collaborative use of Computer-Assisted Argumentation Mapping to evaluate competing theories influence the critical thinking skill of argument evaluation, metacognitive awareness, and conceptual knowledge acquisition in high school Advanced Placement physics, compared to the more traditional method of text tables that does not employ Computer-Assisted Argumentation Mapping? 2. What are the student perceptions of the pros and cons of argument evaluation in the high school Advanced Placement physics environment? This study examined changes in critical thinking skills, including argumentation evaluation skills, as well as metacognitive awareness and conceptual knowledge, in two groups: a treatment group using Computer-Assisted Argumentation Mapping to evaluate physics arguments, and a comparison group using text tables to evaluate physics arguments. Quantitative and qualitative methods for collecting and analyzing data were used to answer the research questions. Quantitative data indicated no significant difference between the experimental groups, and qualitative data suggested students perceived pros and cons of argument evaluation in the high school Advanced Placement physics environment, such as self-reported sense of improvement in argument evaluation and low perceived value of the learning task, respectively. The discussion presents implications for practice and research, such as introducing motivation scaffolds to support appreciation of task value, and addressing major differences between the design of this study and similar published studies, respectively. This work provides contributions in that it tested the effect of Computer-Assisted Argumentation Mapping on the critical thinking skills of twelfth-grade students within the context of evaluating physics arguments, a previously unexplored age group and domain.

Experimentally reduced corticosterone release promotes early breeding in black-legged kittiwakes.

Breeding at the right time is important for successful reproduction. In birds, stressful environmental conditions are known to delay the timing of breeding but the underlying mechanisms are poorly understood. The stress hormone corticosterone appears to be a good candidate for mediating egg-laying date according to early environmental conditions and physiological state. By experimentally reducing the release of corticosterone in black-legged kittiwakes during the pre-laying period, we tested whether egg-laying date was mechanistically linked to corticosterone levels. Male and female kittiwakes were implanted with a low dose of exogenous corticosterone to inhibit endogenous corticosterone production. According to our predictions, the experimental reduction of corticosterone release was paralleled by a significant advancement of egg laying in females (around 4 days earlier). In addition, females with experimentally reduced corticosterone release gained mass during the pre-laying period compared with controls. Ultimately, the advancement of egg laying in females with experimentally reduced corticosterone levels was associated with an enhanced breeding success. This effect was strongly sex specific. In corticosterone-treated male kittiwakes, egg-laying date and reproductive success were not affected, but breeding probability was lower than in controls. This corticosterone treatment did not influence immediate clutch size, or return rate and breeding decision the following year. Our results support the hypothesis that corticosterone secretion during the pre-laying period mediates the timing of breeding in this long-lived seabird, possibly through the dynamics of energy reserves.

The length and time scales of water's glass transitions

NASA Astrophysics Data System (ADS)

Limmer, David T.

2014-06-01

Using a general model for the equilibrium dynamics of supercooled liquids, I compute from molecular properties the emergent length and time scales that govern the nonequilibrium relaxation behavior of amorphous ice prepared by rapid cooling. Upon cooling, the liquid water falls out of equilibrium whereby the temperature dependence of its relaxation time is predicted to change from super-Arrhenius to Arrhenius. A consequence of this crossover is that the location of the apparent glass transition temperature depends logarithmically on cooling rate. Accompanying vitrification is the emergence of a dynamical length-scale, the size of which depends on the cooling rate and varies between angstroms and tens of nanometers. While this protocol dependence clarifies a number of previous experimental observations for amorphous ice, the arguments are general and can be extended to other glass forming liquids.

Are archetypes transmitted or emergent? A response to Christian Roesler.

PubMed

Martin-Vallas, François

2013-04-01

In this paper the author argues that Jung's concept of archetype should not be reduced to an univocal definition. Jung himself proposed many definitions of this concept, some of them being partially or totally contradictory to others. A univocal and logical way of thinking can lead us to refute and reject part of those definitions, but a complex way of thinking, as proposed by Edgar Morin or Roy Bhaskar for example, can allow us to consider that those apparent contradictions in Jung's definitions of archetype reflect the complexity of the psychic reality. The main argument of the author is that Jung was missing the epistemological concept of emergence (which appeared in science at the time of his death) and that he tried to express it with the epistemological concepts of his time. © 2013, The Society of Analytical Psychology.

Electronic media, violence, and adolescents: an emerging public health problem.

Adolescents' access to and use of new media technology (e.g., cell phone, personal data assistant, computer for Internet access) are on the rise, and this explosion of technology brings with it potential benefits and risks. Attention is growing about the risk of adolescents to become victims of aggression perpetrated by peers with new technology. In September 2006, the Centers for Disease Control and Prevention convened a panel of experts in technology and youth aggression to examine this specific risk. This special issue of the Journal of Adolescent Health presents the data and recommendations for future directions discussed at the meeting. The articles in the Journal support the argument that electronic aggression is an emerging public health problem in need of additional prevalence and etiological research to support the development and evaluation of effective prevention programs.

Random topologies and the emergence of cooperation: the role of short-cuts

Vilone, D.; Sánchez, A.; Gómez-Gardeñes, J.

2011-04-01

We study in detail the role of short-cuts in promoting the emergence of cooperation in a network of agents playing the Prisoner's Dilemma game (PDG). We introduce a model whose topology interpolates between the one-dimensional Euclidean lattice (a ring) and the complete graph by changing the value of one parameter (the probability p of adding a link between two nodes not already connected in the Euclidean configuration). We show that there is a region of values of p in which cooperation is greatly enhanced, whilst for smaller values of p only a few cooperators are present in the final state, and for p\\rightarrow 1^- cooperation is totally suppressed. We present analytical arguments that provide a very plausible interpretation of the simulation results, thus unveiling the mechanism by which short-cuts contribute to promoting (or suppressing) cooperation.

Explanation can cause Forgetting: Memory Dynamics in the Generation of New Arguments.

PubMed

Soares, Julia S; Storm, Benjamin C

2017-10-01

Retrieval-induced forgetting is observed when the retrieval of target information causes the forgetting of nontarget information. The present study investigated whether similar dynamics occur in the context of generating arguments in the process of explanation. Participants studied arguments associated with several issues before attempting to think of new arguments pertaining to a subset of those issues. When given a later memory test, participants were less likely to recall the studied arguments if they had attempted to think of new arguments than if they had not. This argument-induced forgetting effect was observed regardless of whether participants attempted to generate arguments that either agreed or disagreed with the position of the arguments they studied. The effect was significantly reduced, however, and even numerically reversed, when participants generated arguments that were highly related to the studied arguments. This finding fits well with previous research on retrieval-induced forgetting, which has shown that the retrieval or generation of new information fails to cause the forgetting of old information when the two types of information are well integrated or semantically associated.

Evolution as represented through argumentation: A qualitative study on reasoning and argumentation in high school biology teaching practices

NASA Astrophysics Data System (ADS)

Yalcinoglu, Pelin

This study aimed to explore high school biology teachers' epistemological criteria and their attention to reasoning and argumentation within their instructional practices. This study investigated: (1) what epistemological criteria do high school biology teachers use when justifying the validity of conclusions, (2) what is the frequency of the explicit use of reasoning and argumentation, if any, in high school biology teachers' instructional practices, and to what extend are reasoning and argumentation skills reflected, if at all, in high school biology teachers' modes of assessment. Three different data collection methods were employed in this study; face-to-face interviews, classroom observations, and document collections. Teachers' epistemological criteria were investigated to provide insight about their reasoning structures. This investigation was made possible by having teachers provide an argument about the validity of hypothetical conclusions drawn by the students based on two different scenarios related to evolution. Toulmin's Argument Pattern used to create rubric to analyze high school biology teachers' levels of reasoning through argumentation. Results of the data analysis suggested following findings. First, high school biology teachers participated in this study presented variety of epistemological criteria which were presented as high, moderate and low levels of reasoning through the argumentations. Second, elements of Toulmin's Argument Pattern were visible in the participants teaching practices, however students were not explicitly introduced to a well structured argument in those classrooms. High level of reasoning was not evident in the instructional practices of the observed teachers. High school biology classrooms which were observed in this study do not provide opportunities for students to practice high level of reasoning or improve their argumentation skills. Third, Interview Protocols designed for this study were found useful to identify the epistemological criteria and level of reasoning individuals presented through argumentation. Toulmin's Argument Pattern provides a practical method to analyze the structure of arguments. Results of this study suggest the following implications for improving science education. These implications might be helpful in increasing teacher awareness of the importance of explicit teaching of reasoning and argumentation in science classrooms. Toulmin's Argument Model should be introduced to teachers through teacher education or professional development programs to increase the use of reasoning and argumentation skills in instructional practices. Toulmin's Argument Pattern may be used to design lessons or unit plans which present science as argumentation. Therefore, by engaging students in argumentation, teachers may help students to improve their content knowledge along with reasoning and argumentation skills in science classrooms. The results of this study suggest that use of Toulmin's Argument Pattern to evaluate high school biology teachers' presented levels of reasoning is a promising approach to understanding the structure of reasoning and argumentation that biology teachers use when providing judgments about the validity of hypothetical conclusions. The interview protocols and the rubrics used in this study should be tested in different subject areas in order to enhance and validate the use of Toulmin's Argument Pattern in measuring individuals' epistemological criteria and level of reasoning.

Argument structure hierarchy system and method for facilitating analysis and decision-making processes

DOEpatents

Janssen, Terry

2000-01-01

A system and method for facilitating decision-making comprising a computer program causing linkage of data representing a plurality of argument structure units into a hierarchical argument structure. Each argument structure unit comprises data corresponding to a hypothesis and its corresponding counter-hypothesis, data corresponding to grounds that provide a basis for inference of the hypothesis or its corresponding counter-hypothesis, data corresponding to a warrant linking the grounds to the hypothesis or its corresponding counter-hypothesis, and data corresponding to backing that certifies the warrant. The hierarchical argument structure comprises a top level argument structure unit and a plurality of subordinate level argument structure units. Each of the plurality of subordinate argument structure units comprises at least a portion of the grounds of the argument structure unit to which it is subordinate. Program code located on each of a plurality of remote computers accepts input from one of a plurality of contributors. Each input comprises data corresponding to an argument structure unit in the hierarchical argument structure and supports the hypothesis or its corresponding counter-hypothesis. A second programming code is adapted to combine the inputs into a single hierarchical argument structure. A third computer program code is responsive to the second computer program code and is adapted to represent a degree of support for the hypothesis and its corresponding counter-hypothesis in the single hierarchical argument structure.

Gambler Risk Perception: A Mental Model and Grounded Theory Analysis.

Spurrier, Michael; Blaszczynski, Alexander; Rhodes, Paul

2015-09-01

Few studies have investigated how gamblers perceive risk or the role of risk perception in disordered gambling. The purpose of the current study therefore was to obtain data on lay gamblers' beliefs on these variables and their effects on decision-making, behaviour, and disordered gambling aetiology. Fifteen regular lay gamblers (non-problem/low risk, moderate risk and problem gamblers) completed a semi-structured interview following mental models and grounded theory methodologies. Gambler interview data was compared to an expert 'map' of risk-perception, to identify comparative gaps or differences associated with harmful or safe gambling. Systematic overlapping processes of data gathering and analysis were used to iteratively extend, saturate, test for exception, and verify concepts and themes emerging from the data. The preliminary findings suggested that gambler accounts supported the presence of expert conceptual constructs, and to some degree the role of risk perception in protecting against or increasing vulnerability to harm and disordered gambling. Gambler accounts of causality, meaning, motivation, and strategy were highly idiosyncratic, and often contained content inconsistent with measures of disordered gambling. Disordered gambling appears heavily influenced by relative underestimation of risk and overvaluation of gambling, based on explicit and implicit analysis, and deliberate, innate, contextual, and learned processing evaluations and biases.

‘Maintaining balance and harmony’: Javanese perceptions of health and cardiovascular disease

Dewi, Fatwa S.T.; Weinehall, Lars; Öhman, Ann

2010-01-01

Community intervention programmes to reduce cardiovascular disease (CVD) risk factors within urban communities in developing countries are rare. One possible explanation is the difficulty of designing an intervention that corresponds to the local context and culture. Objectives To understand people's perceptions of health and CVD, and how people prevent CVD in an urban setting in Yogyakarta, Indonesia. Methods A qualitative study was performed through focus group discussions and individual research interviews. Participants were selected purposively in terms of socio-economic status (SES), lay people, community leaders and government officers. Data were analysed by using content analysis. Results Seven categories were identified: (1) heart disease is dangerous, (2) the cause of heart disease, (3) men have no time for health, (4) women are caretakers for health, (5) different information-seeking patterns, (6) the role of community leaders and (7) patterns of lay people's action. Each category consists of sub-categories according to the SES of participants. The main theme that emerged was one of balance and harmony, indicating the necessity of assuring a balance between ‘good’ and ‘bad’ habits. Conclusions The basic concepts of balance and harmony, which differ between low and high SES groups, must be understood when tailoring community interventions to reduce CVD risk factors.

This study focuses on lay conceptions of intelligence. It examined sex and cross-cultural similarities and differences in estimated intelligences and beliefs about intelligence in two countries, Angola and East Timor, within the reversal theory framework. A total of 209 Angolan (109 women and 100 men) and 183 Timorese (89 women and 94 men) students were participated in this study. Participants completed a questionnaire in order to estimate their parents', partners' and own overall intelligence and the 8 reversal multiple intelligences (telic, paratelic, conformist, negativistic, autic mastery, autic sympathy, alloic mastery and alloic sympathy intelligence). Respondents also rated 6 questions about intelligence. Men rated their overall, conformist and autic mastery higher than women. Angolans rated their overall, telic, paratelic, conformist, negativistic, autic mastery, autic sympathy, alloic mastery and alloic sympathy intelligence higher than Timorese. In both countries, fathers have been perceived as more intelligent than mothers, and telic intelligence emerged as a significant predictor of overall intelligence. Principal component analysis of the 8 reversal multiple intelligences yielded one factor. Angolan participants revealed more IQ test experience than Timorese participants. Most of respondents in both countries did not believe in sex differences in intelligence. These findings are discussed by means of cross-cultural literature. © 2015 International Union of Psychological Science.

Birds from Rhode Island Red (RIR) origin show a lower fear response and less feather pecking than birds from White Leghorn (WL) origin. This study investigated whether responses in fear eliciting tests were affected if RIR and WL birds were housed together. Experimental groups contained either birds from one line only ('pure' groups) or an equal number of RIR and WL birds ('mixed' groups). These arrangements were maintained from hatch onwards, throughout the rearing and laying period. Birds were subjected to open field tests at 5-6 weeks and 17-18 weeks of age and to manual restraint tests at 7-8 weeks and 24 weeks of age. RIR birds were more active in both open field tests and in the manual restraint test at 24 weeks of age as compared with WL birds. RIR birds from pure groups were more active in the open field test at 17-18 weeks and in the manual restraint test at 24 weeks of age than RIR birds from mixed groups. These results suggest that otherwise low fearful RIR birds may adopt a higher fear response if they are housed together with more fearful conspecifics. These effects do not emerge until after 8 weeks of age.

Sometimes a cigar [magazine] is more than just a cigar [magazine]: pro-smoking arguments in Cigar Aficionado, 1992-2000.

2003-01-01

Since its first issue in 1992, few periodicals have enjoyed the rapid growth and international popularity of Cigar Aficionado. Although the magazine professes to simply celebrate "the good life and the joys of cigar smoking," we argue that it serves a more insidious function; specifically, the periodical supplies readers with 7 persuasive strategies aimed at rebuking dominant anti-smoking health assertions: (a) the cigars-are-not-cigarettes argument, (b) the life-is-dangerous argument, (c) the health-benefits argument, (d) the moderation argument, (e) the old-smokers argument, (f) the bad-science argument, and (g) the good-science argument. These pro-smoking arguments ultimately serve to relieve the cognitive dissonance associated with the consumption of a potentially deadly product and to maintain a loyal readership, free from guilt or anxiety.

All samples were tested for flexural strength using three point load test. A statistical mathematical model was developed to correlate the processing parameters with flexural strength. The result clearly demonstrated that the lay-up thickness and nozzle diameter influenced flexural strength significantly, whereas lay-up speed hardly influenced the flexural strength.

Numerous studies have demonstrated influences of hybrid, feed, and housing on prevalence of keel bone fractures, but influences of behavior and production on an individual level are less known. In this longitudinal study, 80 white and brown laying hens were regularly checked for keel bone deviations and fractures while egg production was individually monitored using Radio Frequency Identification (RFID) from production until depopulation at 65 weeks of age. These focal birds were kept in eight pens with 20 hens per pen in total. About 62% of the hens had broken keel bones at depopulation. The occurrence of new fractures was temporally linked to egg laying: more new fractures occurred during the time when laying rates were highest. Hens with fractured keel bones at depopulation had laid their first egg earlier than hens with intact keel bones. However, the total number of eggs was neither correlated with the onset of egg laying nor with keel bone fractures. All birds with bumblefoot on both feet had a fracture at depopulation. Hens stayed in the nest for a longer time during egg laying during the ten days after the fracture than during the ten days before the fracture. In conclusion, a relationship between laying rates and keel bone fractures seems likely.

Understanding Lay Assessments of Alcohol Use Disorder: Need for Treatment and Associated Stigma.

Three-quarters of people with an alcohol use disorder in the USA never receive treatment. Our understandings of who receives care are informed by sociological perspectives, theories and models, each of which discuss the role of lay people's understanding of illness. However, comparatively little work has been done to unpack the cognitive processes underlying lay assessment. In the context of the Framework Integrating Normative Influences on Stigma (FINIS), we aim to understand key factors guiding lay people's stigmatizing attitudes, perceptions and assessments of alcohol use disorder behaviors. Lay people read a vignette depicting a male or female adult with a diagnosable alcohol use disorder, along with either a causal life-event explanation for the alcohol use disorder behaviors or no explanation. They then made judgments of the need for treatment, psychological abnormality and the stigma they felt toward the person depicted. Causal life-event explanations decreased lay judgments of the need for treatment, psychological abnormality and stigma. The results suggest that the availability of a causal life-event explanation may have a complex effect on lay judgments, decreasing the likelihood of recommending treatment for alcohol use disorders, yet simultaneously reducing stigmatizing perceptions (and presumably social distance). © The Author 2015.

To conduct a qualitative systematic review on the use of lay counsellors in South Africa to provide lessons on optimizing their use for psychological and behavioural change counselling for chronic long-term care in scare-resource contexts. A qualitative systematic review of the literature on lay counsellor services in South Africa. Twenty-nine studies met the inclusion criteria. Five randomized control trials and two cohort studies reported that lay counsellors can provide behaviour change counselling with good outcomes. One multi-centre cohort study provided promising evidence of improved anti-retroviral treatment adherence and one non-randomized controlled study provided promising results for counselling for depression. Six studies found low fidelity of lay counsellor-delivered interventions in routine care. Reasons for low fidelity include poor role definition, inconsistent remuneration, lack of standardized training, and poor supervision and logistical support. Within resource-constrained settings, adjunct behaviour change and psychological services provided by lay counsellors can be harnessed to promote chronic care at primary health care level. Optimizing lay counsellor services requires interventions at an organizational level that provide a clear role definition and scope of practice; in-service training and formal supervision; and sensitization of health managers to the importance and logistical requirements of counselling.

To analyze gender differences in levels of psychological distress, financial strain, lay off experiences and job search activity among unemployed and re-employed individuals who were laid-off due to the collapse of the financial sector in Iceland in 2008. The study is based on questionnaires distributed to 759 former financial sector employees; 426 responses were received giving a 62.6% response rate. The groups of unemployed and re-employed woman and men are compared using separate multivariate binary models to control for mediating factors. The analysis reveals gender differences in demographic factors and jobs held prior to lay-off. More women than men were psychologically or finically distressed and claimed being shocked by the lay-off. A higher proportion of men than women were re-employed at the time of this study. The main difference between those re-employed and unemployed was lower financial strain among those re-employed for both men and women in this sample. The study does not support the traditional view of men having more difficulties in the lay-off process than women. This calls for a rethinking regarding gender in lay-off and unemployment. A gender-based analysis is needed when considering the ramifications of losing a job and job search activity in the lay-off process.

Background The husbandry systems for laying hens were changed in Sweden during the years 2001 – 2004, and an increase in the number of submissions for necropsy from laying hen farms was noted. Hence, this study was initiated to compare causes of mortality in different housing systems for commercial laying hens during this change. Methods Based on results from routine necropsies of 914 laying hens performed at the National Veterinary Institute (SVA) in Uppsala, Sweden between 2001 and 2004, a retrospective study on the occurrence of diseases and cannibalism, i.e., pecking leading to mortality, in different housing systems was carried out. Using the number of disease outbreaks in caged flocks as the baseline, the expected number of flocks with a certain category of disease in the other housing systems was estimated having regard to the total number of birds in the population. Whether the actual number of flocks significantly exceeded the expected number was determined using a Poisson distribution for the variance of the baseline number, a continuity correction and the exact value for the Poisson distribution function in Excel 2000. Results Common causes of mortality in necropsied laying hens included colibacillosis, erysipelas, coccidiosis, red mite infestation, lymphoid leukosis and cannibalism. Less common diagnoses were Newcastle Disease, pasteurellosis and botulism. Considering the size of the populations in the different housing systems, a larger proportion of laying hens than expected was submitted for necropsy from litter-based systems and free range production compared to hens in cages (P < 0.001). The study showed a significantly higher occurrence of bacterial and parasitic diseases and cannibalism in laying hens kept in litter-based housing systems and free-range systems than in hens kept in cages (P < 0.001). The occurrence of viral diseases was significantly higher in indoor litter-based housing systems than in cages (P < 0.001). Conclusion The results of the present study indicated that during 2001–2004 laying hens housed in litter-based housing systems, with or without access to outdoor areas, were at higher risk of infectious diseases and cannibalistic behaviour compared to laying hens in cages. Future research should focus on finding suitable prophylactic measures, including efficient biosecurity routines, to reduce the risk of infectious diseases and cannibalism in litter-based housing systems for laying hens.

The nature and development of hypothetico-predictive argumentation with implications for science teaching

2003-11-01

This paper explicates a pattern of scientific argumentation in which scientists respond to causal questions with the generation and test of alternative hypotheses through cycles of hypothetico-predictive argumentation. Hypothetico-predictive arguments are employed to test causal claims that exist on at least two levels (designated stage 4 in which the causal claims are perceptible, and stage 5 in which the causal claims are imperceptible). Origins of the ability to construct and comprehend hypothetico-predictive arguments at the highest level can be traced to pre-verbal reasoning of the sensory-motor child and the gradual internalization of verbally mediated arguments involving nominal, categorical, causal and, finally, theoretical propositions. Presumably, the ability to construct and comprehend hypothetico-predictive arguments (an aspect of procedural knowledge) is necessary for the construction of conceptual knowledge (an aspect of declarative knowledge) because such arguments are used during concept construction and conceptual change. Science instruction that focuses on the generation and debate of hypothetico-predictive arguments should improve students' conceptual understanding and their argumentative/reasoning skills.
