    Full Text Available There is a wide debate among the researchers and clinicians over the diagnostic categories subsumed under the rubric of somatoform disorders (SDs. Recent proposals vary from radical views that call for removing this category altogether to the conservative views that suggests cosmetic changes in the diagnostic criteria of SDs. We have the reviewed the relevant literature through PUBMED search supplemented with manual search on current concepts of SD.

    2007-06-01

    Full Text Available Corporate Social Responsibility (CSR has a particular prominence at this point in time, featuring heavily in the discourses of both academe and business. The understanding of what is meant by CSR continues to evolve as a consensus is reached. Nevertheless some important debates continue – or are commencing – which need to be resolved. It is the purpose of this paper to highlight these as some of the current debates within the CSR community – and hence form a significant part of an agenda for research in the area. Specifically we focus upon three key areas for the management of business, namely setting standards for reporting, identifying and implementing sustainable practice, and the management of risk.

  6. The international financial crisis: Theoretical debates, economic policies, and lessons

    2014-01-01

    Full Text Available The global financial crisis has had a strong impact on most European countries. While at first the massive injection of resources helped the financial system not to collapse, the austerity policies implemented throughout the continent have not brought the expected economic growth. Interestingly, the type of intervention undertaken is rooted in the neoclassical tradition, which entails a specific understanding of the functioning of the financial system and the economy. In this context, the objectives of this paper are firstly, to analyze the main theoretical assumptions and the specific way in which the crisis is understood and the applied economic policies are developed under this tradition; and secondly, to account for the social and economic impact of the policies applied, and the different margins of action that each European country still has.

    2015-01-01

    Female sex trafficking is a pressing concern. In this article, we provide a comprehensive overview of relevant issues regarding the concept of female sex trafficking and research in the field of human trafficking, drawing on a variety of disciplines, including economics, gender and sexuality studies, psychology, sociology, law, and social work. We discuss the debates surrounding the definition of human trafficking, compare and contrast it with human smuggling, and outline connections between female sex trafficking and the issue of sex work and prostitution. We further discuss the history and current estimations of female sex trafficking. We then outline the main actors in female sex trafficking, including trafficked persons, traffickers, clients, and service providers, and we overview the trafficking process from recruitment to identification, recovery, and (re)integration. Finally, we conclude with recommendations for future research that tie together the concepts of vulnerability, exploitation, and long-term recovery and (re)integration.

    2008-01-01

    The paper examines the conceptual context of cultural diversity in Sweden. It describes the background in which the former Social Democratic Government declared 2006 as the Year for Cultural Diversity. A related concern is scrutinizing whether in fact this year would be a starting point for more deeply engaged diversity programs or if such policy definitions remain mere symbolic acts of window dressing. The study is based on analysis of official documents, diversity events and agendas, and interviews with different actors and diversity consultants, and participation in seminars and conferences on the topic of diversity and integration as the main topics. A major concern is whether the current interest on cultural diversity may lead to its institutionalization in the Swedish cultural and social organizations (Hamde, 2002a) and address the virtues of diversity, such as diversity for profitability and competence in workplaces, social justice concerns, and finally, societal cohesion. Alternatively, the paper explores if the debate on diversity merely remains a 'traveling' idea to appear occasionally and then occur in fashion-like manner as many management ideas do, leaving little traces on peoples' lives.

    Full Text Available Curriculum is a set of planned tasks, learning experiences and behaviors proposed by an authority to achieve predetermined goals in form of behavioral change, academic achievements and learning outcomes within a particular time. The scholars are the people who have command and expertise in any of the curriculum components. The article focuses on the role of curriculum scholars in Pakistan and how and what type of changes they can initiate to bring harmony and tolerance, character and quality in development of curricula. The international issues, trends evolving globalization can be enhanced and incorporated to foster individual and social development. It is a qualitative study based on historical evidences and current researches highlighting the importance and role of curriculum scholars and meeting the world class education system. The issues and trends mentioned by developed countries curriculum experts paved way to synthesis them with local rising issues and trends.The study concluded that the curriculum developers have dynamic roles in curriculum debates because they have to work for bridging gaps of developing and developed nation, addressing local curriculum issues, Using pragmatic approach rather than ideological, reorganizing of recent curricula, solving language issue, facing controversies on curriculum change, making it unified and centralized, diverting curricula to research orientation, obtaining continuous feedback and developing harmony in society at the same time. It is imperative for scholars to have effective communication skills and dynamic personality to incorporate the future trends without creating conflicts and confusion in the society. They need to know the skill to motivate and mould high ups for future changes and bring changes without development of controversies.

    2016-10-15

    Despite the considerable amount of research in the field, the management of locally advanced rectal cancer remains a subject to debate. To date, effective treatment centers on surgical resection with the standard approach of total mesorectal resection. Radiation therapy and chemotherapy have been incorporated in order to decrease local and systemic recurrence. While it is accepted that a multimodality treatment regimen is indicated, there remains significant debate for how best to accomplish this in regards to order, dosing, and choice of agents. Preoperative radiation is the standard of care, yet remains debated with the option for chemoradiation, short course radiation, and even ongoing studies looking at the possibility of leaving radiation out altogether. Chemotherapy was traditionally incorporated in the adjuvant setting, but recent reports suggest the possibility of improved efficacy and tolerance when given upfront. In this review, the major studies in the management of locally advanced rectal cancer will be discussed. In addition, future directions will be considered such as the role of immunotherapy and ongoing trials looking at timing of chemotherapy, inclusion of radiation, and non-operative management.

    The vertiginous transformations of the contemporary societies have been raising questions concerning aspects of professional education. Such questions have been raised in a more and more incisive way. This debate gains a new shape when applied to health work, where theory and practice cannot be dissociated, and where the development of an integral vision of the human being and the amplification of the concept care are essential for a proper performance. Based on these considerations, this article aims to discuss the main methodological transformations in the education process of health professionals, with emphasis to active teaching-learning methodologies.

    2016-12-01

    Full Text Available The drafters of the 1982 UN Convention on the Law of the Sea (UNCLOS have left behind a lacunae in terms of the regulations concerning Biodiversity in the Areas Beyond National Jurisdiction (BBNJ. As living organisms are found in the deep seabed in areas beyond national jurisdiction, as well as the utilization of marine genetic resources beyond national jurisdiction for commercial purposes, States are currently deliberating on the proper regime in dealing with the management and exploitation of the biodiversity. Some States argue that Part XI UNCLOS applies hence BBNJ is also part of the Common Heritage of Mankind. On the other hand, some States believe that Part VII UNCLOS applies which will allow individual States to exploit the resources in accordance with the principle of the freedom of the high seas. Since 2004, the UN General Assembly has established a Working Group to discuss the issue. Indonesia as a Party to UNCLOS which in general advocates the importance of the rule of law in the oceans has the interest that the discussion in the UN will allow developing countries, including Indonesia, to enjoy the result of the exploration and exploitation of non-mineral resources at the bottom of the ocean.

    End-of-life sedation, though increasingly prevalent and widespread internationally, remains one of the most highly debated medical practices in the context of palliative medicine. This qualitative study aims to elicit and record the perspectives of leading international palliative care experts on current debates. Twenty-one professionals from diverse backgrounds, sharing field-specific knowledge/expertise defined by significant scholarly contribution on end-of-life sedation, were recruited. Open-ended, semi-structured interviews, following a topic-oriented structure reflecting on current debates, were conducted. Results were analysed using thematic content analysis. Three main aspects of sedation were identified and discussed as potentially problematic: (a) continuous deep sedation as an extreme facet of end-of-life sedation, (b) psycho-existential suffering as an ambivalent indication for sedation and (c) withdrawal or withholding of artificial nutrition and hydration as potentially life-shortening. On these grounds, concerns were reported over end-of-life sedation being morally equivalent to euthanasia. Considerable emphasis was placed on intentions as the distinguishing factor between end-of-life acts, and protective safeguards were introduced to distance sedation from euthanasia. This study shows that, despite the safeguards introduced, certain aspects of sedation, including the intentions associated with the practice, are still under question, parallels being drawn between end-of-life sedation and euthanasia. This reaffirms the existence of a grey area surrounding the two practices, already evidenced in countries where euthanasia is legalized. More clarity over the issues that generate this grey area, with their causes being uncovered and eliminated, is imperative to resolve current debates and effectively inform research, policy and practice of end-of-life sedation.

  19. Current Debates on Variability in Child Welfare Decision-Making: A Selected Literature Review

    Directory of Open Access Journals (Sweden)

    Emily Keddell

    2014-11-01

    Full Text Available This article considers selected drivers of decision variability in child welfare decision-making and explores current debates in relation to these drivers. Covering the related influences of national orientation, risk and responsibility, inequality and poverty, evidence-based practice, constructions of abuse and its causes, domestic violence and cognitive processes, it discusses the literature in regards to how each of these influences decision variability. It situates these debates in relation to the ethical issue of variability and the equity issues that variability raises. I propose that despite the ecological complexity that drives decision variability, that improving internal (within-country decision consistency is still a valid goal. It may be that the use of annotated case examples, kind learning systems, and continued commitments to the social justice issues of inequality and individualisation can contribute to this goal.

  1. Achieving universal health care coverage: Current debates in Ghana on covering those outside the formal sector

    2012-10-01

    Full Text Available Abstract Background Globally, extending financial protection and equitable access to health services to those outside the formal sector employment is a major challenge for achieving universal coverage. While some favour contributory schemes, others have embraced tax-funded health service cover for those outside the formal sector. This paper critically examines the issue of how to cover those outside the formal sector through the lens of stakeholder views on the proposed one-time premium payment (OTPP policy in Ghana. Discussion Ghana in 2004 implemented a National Health Insurance Scheme, based on a contributory model where service benefits are restricted to those who contribute (with some groups exempted from contributing, as the policy direction for moving towards universal coverage. In 2008, the OTPP system was proposed as an alternative way of ensuring coverage for those outside formal sector employment. There are divergent stakeholder views with regard to the meaning of the one-time premium and how it will be financed and sustained. Our stakeholder interviews indicate that the underlying issue being debated is whether the current contributory NHIS model for those outside the formal employment sector should be maintained or whether services for this group should be tax funded. However, the advantages and disadvantages of these alternatives are not being explored in an explicit or systematic way and are obscured by the considerable confusion about the likely design of the OTPP policy. We attempt to contribute to the broader debate about how best to fund coverage for those outside the formal sector by unpacking some of these issues and pointing to the empirical evidence needed to shed even further light on appropriate funding mechanisms for universal health systems. Summary The Ghanaian debate on OTPP is related to one of the most important challenges facing low- and middle-income countries seeking to achieve a universal health care system. It

    Full Text Available Irritability is defined as a low threshold to experience anger in response to frustration. It is one of the most common symptoms in youth and is part of the clinical presentation of several disorders. Irritability can present early in life and is a predictor of long-term psychopathology; yet, the diagnostic status of irritability is a matter of intense debate. In the present article, we address two main components of the debate regarding irritability in youth: the misdiagnosis of chronic irritability as pediatric bipolar disorder, and the proposal of a new diagnosis in the DSM-5, disruptive mood dysregulation disorder, whose defining symptoms are chronic irritability and temper outbursts.

  5. Islamic Theoretical Intertemporal Model of the Current Account

    Directory of Open Access Journals (Sweden)

    Hassan Belkacem Ghassan

    2016-06-01

    Full Text Available This paper aims to develop an Islamic intertemporal model of the current account based on the prevailing theoretical and empirical literature of PVMCA (Obstfeld and Rogoff, 1996, Cerrato et al., 2014. The proposed model is based on the budget constraint of the present and future consumption, which depends on the obligatory Zakat from the income and assets, the return rate on the owned assets, the inheritance linking previous to subsequent generation. Using logarithmic utility function, featured by a unitary elasticity of intertemporal substitution and a unitary coefficient of relative risk aversion, we show through Euler equation of consumption that there is an inverse relationship between consumption growth from the last age to the first one and the Zakat rate on assets. The outcomes of this result are that the Zakat on assets disciplines the consumer to have more rationality in consumption, and allows additional marginal assets for future generations. By assuming a unitary subjective discount rate, we indicate that the more the return rate on assets is high, the more the consumption growth between today and tomorrow will be fast. Through the budget constraint, if Zakat rate on the Zakatable assets is greater than Zakat rate on income, this leads to a relative expansion in private consumption of the wealthy group. Besides, we point out that an increase in return rate on assets, can drive to increasing or decreasing current consumption, because the substitution and income effects work in opposite ways.

    2013-11-01

    Full Text Available The Higher Education Act now in force in Argentina, was from its beginning an argued and ideologically questioned law. Different sectors resisted this piece of legislation and the institutional changes it outlined for Higher Education, especially for universities. Today, almost two decades afterwards, questioning goes on and a lot of people plead for a change they consider of necessity. The following text conteins some reflections of the author set out in a public debate on the issue, organized by the rectorships of Universidad Nacional de Córdoba and Universidad Nacional de Río Cuarto, in October 2013.

    Full Text Available This paper addresses the research landscape of Intellectual PropertyRights. It describes and probes the key players and the mostinfluential journal publications. While most literature reviews arequalitative, in many cases highly subjective and necessarily selective,this paper takes another course. By using Social NetworkAnalysis and the Co-Author Citation Approach it constructs aquantitative approach. The outcome is threefold. First, the workswith the most influence are identified, as are 9 sub-networks intowhich the Intellectual Property research splits. Second, the researchinstitutions and their networks are analyzed. This researchillustrates that the Intellectual Property research landscape isshaped by a handful of universities, the rest follow suit. Third, itis demonstrated that North America dominates the academic IntellectualProperty debate by far. Regions such as South Americaand Africa do not even appear in the body of knowledge. This papergives an overview of Intellectual Property research. Based onthe quantitative output further research questions can be formulated.

  8. Two Reflexivities in Current Social Science: Remarks on an Absent Debate

    Directory of Open Access Journals (Sweden)

    Andreas Langenohl

    2009-02-01

    Full Text Available This paper traces and compares two different uses of the category of reflexivity in contemporary methodological debates in the social sciences. While a first use is strongly influenced by the textual turn in cultural anthropology, a second use is aligned with Pierre BOURDIEU's notion of "scientific reflexivity." Whereas the first use postulates an epistemological break with scientific modernity and argues for a perpetual contextualization and interrelation of research results and methods, BOURDIEU defends sociology’s claim of objectivity, which, according to him, can be redeemed through a reflexive objectification of sociological practice. Up to the present these two uses have existed in almost complete isolation from each other. They represent alternating reactions to, and reconstructions and translations of, poststructuralism and postmodernism in the social sciences. URN: urn:nbn:de:0114-fqs090297

  9. A debate on current eating disorder diagnoses in light of neurobiological findings: is it time for a spectrum model?

    Directory of Open Access Journals (Sweden)

    Brooks Samantha

    2012-07-01

    Full Text Available Abstract Background Sixty percent of eating disorders do not meet criteria for anorexia- or bulimia nervosa, as defined by the Diagnostic and Statistical Manual version 4 (DSM-IV. Instead they are diagnosed as ‘eating disorders not otherwise specified’ (EDNOS. Discrepancies between criteria and clinical reality currently hampering eating disorder diagnoses in the DSM-IV will be addressed by the forthcoming DSM-V. However, future diagnoses for eating disorders will rely on current advances in the fields of neuroimaging and genetics for classification of symptoms that will ultimately improve treatment. Discussion Here we debate the classification issues, and discuss how brain imaging and genetic discoveries might be interwoven into a model of eating disorders to provide better classification and treatment. The debate concerns: a current issues in the classification of eating disorders in the DSM-IV, b changes proposed for DSM-V, c neuroimaging eating disorder research and d genetic eating disorder research. Summary We outline a novel evidence-based ‘impulse control’ spectrum model of eating disorders. A model of eating disorders is proposed that will aid future diagnosis of symptoms, coinciding with contemporary suggestions by clinicians and the proposed changes due to be published in the DSM-V.

    – and their combination with process tracing. Our goal is to broaden and deepen set-theoretic empirical research and equip scholars with guidance on how to implement it in multi-method research (MMR). At first glance, set-theoretic cross-case methods and process tracing seem to be highly compatible when causal...... relationships are conceptualized in terms of set-theory. However, multiple issues have not so far been thoroughly addressed. Our paper builds on the emerging MMR literature and seeks to enhance it in four ways. First, we offer a comprehensive and coherent elaboration of the two sequences in which case studies...

    2016-01-01

    The shortage of suitable organs and achieved tolerance are uncontested main concerns in transplantation. Long waiting lists for deceased donors and limited numbers of living donors are the current scenarios. Kidney grafts from living donors have better overall survival compared to cadaveric and require less aggressive immunosuppressive regimens. The human leukocyte antigen (HLA) labs have the key role to test the recipient and donors compatibility based on typing and antibody profile. The current standard molecular procedure in solid organ transplantation is low-resolution typing, at the antigen level. In this commentary, the merits of high versus low degree of typing resolution in solid organ transplantation are discussed. Critical questions and reasons to bring high-resolution typing as a routine test in health system are considered. Specifically, with the introduction of the next-generation sequencing (NGS) in HLA, the pros and cons in living donation and benefits after deceased donation are critically evaluated. NGS has the potential to improve the transplant rates and the overall graft survival. Alternative strategies to increase in demanding the number of transplants are briefly highlighted.

  16. Reproductive technology and the life course: current debates and research in social egg freezing.

    Science.gov (United States)

    Baldwin, Kylie; Culley, Lorraine; Hudson, Nicky; Mitchell, Helene

    2014-09-01

    While there are currently few confirmed births from previously frozen eggs in the UK, the improved outcomes of new technologies of vitrification and intra-cytoplasmic sperm injection (ICSI) have led to the marketing of egg freezing for non-medical reasons, whereby women are offered the possibility of preserving their eggs until such time as they wish to have a child. Non-academic commentary on this phenomenon has commonly constructed it within a neo-liberal discourse of 'choice', whereby women are positioned as choosing to 'delay motherhood,' often for reasons relating to their careers. However, there have been relatively few research studies which explore either women's awareness and understandings of social egg freezing or the reasons why women consider or undertake egg freezing. This paper summarises the current academic discussion surrounding social egg freezing and outlines the limited body of empirical literature identified from a systematic search of relevant databases. The potential benefits and harms of social egg freezing and the ethical issues it raises are well rehearsed in existing literature, but there is limited empirical evidence about who is accessing social egg freezing, why they are taking this option and what their experiences and future intentions are.

  17. Current Density Imaging through Acoustically Encoded Magnetometry: A Theoretical Exploration

    CERN Document Server

    Sheltraw, Daniel J

    2014-01-01

    The problem of determining a current density confined to a volume from measurements of the magnetic field it produces exterior to that volume is known to have non-unique solutions. To uniquely determine the current density, or the non-silent components of it, additional spatial encoding of the electric current is needed. In biological systems such as the brain and heart, which generate electric current associated with normal function, a reliable means of generating such additional encoding, on a spatial and temporal scale meaningful to the study of such systems, would be a boon for research. This paper explores a speculative method by which the required additional encoding might be accomplished, on the time scale associated with the propagation of sound across the volume of interest, by means of the application of a radially encoding pulsed acoustic spherical wave.

  18. Reflections on the state of current debate over physician-assisted suicide and euthanasia.

    1995-07-01

    This paper is part of a larger project. My overall aim is to argue that the evolution of familiar forms of termination of life sustaining treatment, constituting so called passive euthanasia, has severely undercut the logic of every form of reasoning that has traditionally been used to oppose active euthanasia and assistance in suicide. Basically, there are two such forms of traditional opposition, each represented in a range of different versions. There is the inevitable argument concerning social utilities -- that permitting euthanasia and assisted suicide will have bad social consequences. But more fundamentally, the idea persists that killing is intrinsically worse than letting-die in some sense that justifies the current practice of prohibiting the first while allowing the latter. In this paper, I first consider this latter claim. My ultimate strategy, as I have said, is to show that the nature of certain things we have all come to approve regarding termination of treatment makes it next to impossible to convincingly explain, in either of these ways, what is wrong with certain forms of assistance in suicide and euthanasia. In the second part of this paper I take another step in this direction by discussing, in a preliminary way, a special case of the argument from social risks.

  19. Autonomy is a Right, Not a Feat: How Theoretical Misconceptions have Muddled the Debate on Dynamic Consent to Biobank Research.

    Should people be involved as active participants in longitudinal medical research, as opposed to remaining passive providers of data and material? We argue in this article that misconceptions of 'autonomy' as a kind of feat rather than a right are to blame for much of the confusion surrounding the debate of dynamic versus broad consent. Keeping in mind two foundational facts of human life, freedom and dignity, we elaborate three moral principles - those of autonomy, integrity and authority - to better see what is at stake. Respect for autonomy is to recognize the other's right to decide in matters that are important to them. Respect for integrity is to meet, in one's relationship with the other, their need to navigate the intersection between private and social life. Respect for authority is to empower the other - to help them to cultivate their responsibility as citizens. On our account, to force information onto someone who does not want it is not to respect that person's autonomy, but to violate integrity in the name of empowerment. Empowerment, not respect for autonomy, is the aim that sets patient-centred initiatives employing a dynamic consent model apart from other consent models. Whether this is ultimately morally justified depends on whether empowerment ought to be a goal of medical research, which is questionable.

  20. A review of the current geographic distribution of and debate surrounding electronic cigarette clean air regulations in the United States.

    In this article, we present the results of a systematic review of state, county, and municipal restrictions on the use of electronic cigarettes (e-cigarettes) in public spaces within the United States, alongside an overview of the current legal landscape. The lack of federal guidance leaves lower-level jurisdictions to debate the merits of restrictions on use in public spaces without sufficient scientific research. As we show through a geographic assessment of restrictions, this has resulted in an inconsistent patchwork of e-cigarette use bans across the United States of varying degrees of coverage. Bans have emerged over time in a manner that suggests a "bottom up" diffusion of e-cigarette clean air policies. Ultimately, the lack of clinical and scientific knowledge on the risks and potential harm reduction benefits has led to precautionary policymaking, which often lacks grounding in empirical evidence and results in spatially uneven diffusion of policy.

    2016-05-01

    Full Text Available The political and economic crisis of Europe and the austerity programs within EU countries have brought back to center the issues of inequality and social justice in Europe that during the Twentieth century have been addressed through the institutionalization of social citizenship. Europeanization and globalization challenge social cohesion and alters the basic institutions on which social citizenship was constructed in welfare societies. Starting from the results of an empirical study, the aim of this article is to give new impulses to the theoretical reflection on social citizenship as a distinct issue, although related with the concept of citizenship. The focus of the analysis is on members of transnational civil society organizations and their ideas and practices enhancing new forms of a more inclusive and sustainable social citizenship. Conclusions discuss how social bonds and solidarity are reframed transnationally across national, regional, European and global borders, and the implications of this process for the reformulation of the concept of social citizenship.

    Full Text Available At present, a debate has raised on the clinical method as priority policy in health services. Internists are at the forefront of these discussions. The clinical method is a variant of the scientific method applied to the medical assistance of a single individual. It is aimed at the obtention of the most accurate diagnosis, the elaboration of a prognosis and the materialization of action. The conceptualization of the clinical method that prevails among Cuban internists, results from the National School of Clinic, where internists have played a key role during the last 50 years. Their task now is to continue to preserve and transmit this treasure that the essence of clinics is, in an unstable and changing setting. Other clinicians can also join this effort. In this paper, a number of actions are proposed to achieve these purposes.Actualmente ha resurgido un debate en torno al método clínico como política priorizada en el sector de la salud. Los internistas están en la primera fila de estas discusiones. El método clínico es la variante del método científico aplicado a la actividad médica asistencial individual de una persona, con el propósito de llegar al diagnóstico más probable, emitir un pronóstico y tomar la conducta a seguir. La conceptualización del método clínico es fruto de la Escuela Cubana de Clínica, donde los internistas han tenido un papel protagónico en los últimos 50 años y están llamados a continuar con la tarea de mantener y transmitir este tesoro de la esencia misma de la clínica, en un ambiente inestable y cambiante, junto a los demás médicos clínicos que pueden incorporarse a esta labor. En este trabajo se proponen una serie de acciones para lograr estos propósitos.

    Tiina Seppälä

    2012-03-01

    Full Text Available The political revival of the anti-war movement after 9/11 launched a controversial debate on global resistance against war. Liberal cosmopolitans characterise the movement as a consensual force of opposition against war in the form of global civil society acting on thebasis of ‘universal’ values. Radical poststructuralists consider it a preliminary example of the Multitude, waging ‘a war against war’ as a global body of opposition. For statecentrics, these views are utopian in referring to global struggles and political subjects that do not yet exist, and alarming because global resistance escapes power in the ‘postpolitical’ struggle. Here, the theoretical debate is critically analysed from the perspective of ‘critical theory in political practice’. Through an empirical case study of four organisations within the new anti-war movement in Britain, it is demonstrated that these theories’ connection to practice is inadequate, and in many ways problematic due to theirtendency to resort to a dualistic ‘either-or’ logic. The paper introduces a ‘both-and’ approach that not only reflects more accurately the way in which the relationship between global and local is conceived within the movement but also provides a more comprehensive perspective for conceptualising power in the context of social movements generally.

    Ogawa, Tomoyuki; Wakao, Shinji; Taufiq, Jat; Kondo, Keiichiro; Terauchi, Nobuo

    The harmonics of the return current may interfere with the signaling current along with the rails. In this paper, we present the theoretical studies of the return current harmonics in the inverter-controlled DC electric railcar, aiming at contributing future work to improve the compatibility with the signaling current. We theoretically derive sideband harmonics of the DC-link current. Then, in order to verify the theoretical study, we experimentally measure the harmonics and numerically simulate the harmonics. As a result, we concluded the theoretical DC-link current is enough accurate to be utilized for the future improvement of the inverter harmonics current.

    The general magnetic field above the solar photosphere is divided by an elementary analysis based on Ampere's law into two parts: a potential field due to electric currents below the photosphere and a field produced by electric currents above the photosphere combined with the induced mirror currents. The latter, by symmetry, has a set of field lines lying in the plane taken to be the photosphere which may be constructed from given vector magnetograph measurements. These field lines also represent all the information on the electric currents above the photosphere that a magnetograph can provide. Theoretical illustrations are given, and implications for data analysis are discussed.

    New experimental structure determinations for molecular adsorbates on NiO(100) reveal much shorter Ni-C and Ni-N bond lengths for adsorbed CO and NH{sub 3} as well as NO (2.07, 1.88, 2.07{angstrom}) than previously computed theoretical values, with discrepancies up to 0.79{angstrom}, highlighting a major weakness of current theoretical descriptions of oxide-molecule bonding. Comparisons with experimentally determined bond lengths of the same species adsorbed atop Ni on metallic Ni(111) show values on the oxide surface that are consistently larger (0.1--0.3{angstrom}) than on the metal, indicating somewhat weaker bonding.

Una de las causas de este fenómeno se compone de drásticos cambios en la estructura ocupacional de occidente, especialmente en EEUU, que resultaron en una nueva clase media de administradores surgidos de los college devenidos muchos de ellos gerentes de las grandes corporaciones. La emergencia de los gerentes como asalariados pone en cuestión la idea de una clase asalariada homogénea al estilo marxista debido a la expansión de actores tales como burócratas, profesionales, que no se agotan en una explicación dualista o dicotómica de la sociedad.

Estas discusiones suelen soslayar o relegar a un papel secundario la cuestión de las transformaciones en la identidad y la subjetividad dentro del espacio de trabajo. Sostenemos en este trabajo que el espacio laboral ocupa un rol fundamental en la conformación de la identidad. Este supuesto se opone a los pronósticos más optimistas del llamado posfordismo que consideran que la esfera extralaboral es la que imprime su sello sobre el mundo del trabajo.

    A magneto-optical sensor, using a dual quadrature polarimetric processing scheme, was evaluated for current metering and protection applications in high voltage lines. Sensor calibration and resolution were obtained in different operational conditions using illumination in the 1550-nm band. Results obtained indicated the feasibility of interrogating such sensor via the optical ground wire (OPGW) link installed in standard high power grids. The polarimetric bulk optical current sensor also was theoretically studied, and the effects of different sources of error considering practical deployment were evaluated. In particular, the interference from external magnetic fields in a tree-phase system was analyzed.

    重复知盲现象自被发现至今已走过四分之一世纪,这期间重复知盲的产生机制一直是争论的焦点,并有标记个体化理论、类型节点不应期理论、竞争理论、提取失败理论和建构/归因理论等多种理论解释。大量研究证明,重复知盲是一种视知觉失败现象,但也有研究认为它是一种记忆失败现象。很多研究还发现,重复知盲不仅受到呈现时间和间隔刺激个数的限制,还受到实验材料的性质、刺激的空间位置及人们的反应方式等多种因素的影响。近些年来,随着ERP和fMRI等技术的利用,从更深层次揭示了重复知盲产生的脑机制。同时,重复知盲也作为一种实验范式应用于视觉加工领域的研究中。目前关于重复知盲仍然有很多问题值得探索。%It has been over a quarter of a century since the repetition blindness (RB) effect was first reported by Kanwisher (1987) and the precise mechanism underlying RB has been extensively debated. Researchers proposed different theories to account for the effect, for example, it has been argued that RP occurs due to a failure at the visual perception level; alternatively, it has also been argued that RP involves failure to memorize the repeated stimulus. Meanwhile, RB is influenced by many factors, such as presentation durations, lags, experimental materials, spatial locations and tasks. The popularization of neuroscience technology such as ERP and fMRI in recent years allows researchers to reveal the brain activity of RB. As a kind of experimental method, researchers have applied RB effect to explore some phenomena of the visual perception. The current paper reviews these basic research topics. However, many aspects of repetition blindness are still worth of further exploration.

    1990-05-01

    Some designs of liquid-metal current collectors in homopolar motors and generators are essentially rotating liquid-metal fluids in cylindrical channels with free surfaces and will, at critical rotational speeds, become unstable. An investigation at David Taylor Research Center is being performed to understand the role of gravity in modifying this ejection instability. Some gravitational effects can be theoretically treated by perturbation techniques on the axisymmetric base flow of the liquid metal. This leads to a modification of previously calculated critical-current-collector ejection values neglecting gravity effects. The purpose of this paper is to document the derivation of the mathematical model which determines the perturbation of the liquid-metal base flow due to gravitational effects. Since gravity is a small force compared with the centrifugal effects, the base flow solutions can be expanded in inverse powers of the Froude number and modified liquid-flow profiles can be determined as a function of the azimuthal angle. This model will be used in later work to theoretically study the effects of gravity on the ejection point of the current collector.

    1977-01-01

    Measurements of reaction rail currents, reaction rail voltages, and airgap magnetic fields in tests of the Linear Induction Motor Research Vehicle (LIMRV) were compared with theoretical calculations from the mesh/matrix theory. It was found that the rail currents and magnetic fields predicted by the theory are within 20 percent of the measured currents and fields at most motor locations in most of the runs, but differ by as much as a factor of two in some cases. The most consistent difference is a higher experimental than theoretical magnetic field near the entrance of the motor and a lower experimental than theoretical magnetic field near the exit. The observed differences between the theoretical and experimental magnetic fields and currents do not account for the differences of as much as 26 percent between the theoretical and experimental thrusts.

  5. Bioethics Symposium: The ethical food movement: What does it mean for the role of science and scientists in current debates about animal agriculture?

    2012-05-01

    Contemporary animal agriculture is increasingly criticized on ethical grounds. Consequently, current policy and legislative discussions have become highly controversial as decision makers attempt to reconcile concerns about the impacts of animal production on animal welfare, the environment, and on the efficacy of antibiotics required to ensure human health with demands for abundant, affordable, safe food. Clearly, the broad implications for US animal agriculture of what appears to be a burgeoning movement relative to ethical food production must be understood by animal agriculture stakeholders. The potential effects of such developments on animal agricultural practices, corporate marketing strategies, and public perceptions of the ethics of animal production must also be clarified. To that end, it is essential to acknowledge that people's beliefs about which food production practices are appropriate are tied to diverse, latent value systems. Thus, relying solely on scientific information as a means to resolve current debates about animal agriculture is unlikely to be effective. The problem is compounded when scientific information is used inappropriately or strategically to advance a political agenda. Examples of the interface between science and ethics in regards to addressing currently contentious aspects of food animal production (animal welfare, antimicrobial use, and impacts of animal production practices on the environment) are reviewed. The roles of scientists and science in public debates about animal agricultural practices are also examined. It is suggested that scientists have a duty to contribute to the development of sound policy by providing clear and objectively presented information, by clarifying misinterpretations of science, and by recognizing the differences between presenting data vs. promoting their own value judgments in regard to how and which data should be used to establish policy. Finally, the role of the media in shaping public opinions

    2007-01-01

    The Bobath concept is a problem-solving approach to the assessment and treatment of individuals following a lesion of the central nervous system that offers therapists a framework for their clinical practice. The aim of this study was to facilitate a group of experts in determining the current theoretical assumptions underpinning the Bobath concept.A four-round Delphi study was used. The expert sample included all 15 members of the British Bobath Tutors Association. Initial statements were identified from the literature with respondents generating additional statements. Level of agreement was determined by using a five-point Likert scale. Level of consensus was set at 80%. Eighty-five statements were rated from the literature along with 115 generated by the group. Ninety-three statements were identified as representing the theoretical underpinning of the Bobath concept. The Bobath experts agreed that therapists need to be aware of the principles of motor learning such as active participation, opportunities for practice and meaningful goals. They emphasized that therapy is an interactive process between individual, therapist, and the environment and aims to promote efficiency of movement to the individual's maximum potential rather than normal movement. Treatment was identified by the experts as having "change of functional outcome" at its center.

  7. A theoretical analysis of parity violation induced by neutral currents in atomic cesium

    Science.gov (United States)

    Bouchiat, C.; Piketty, C. A.; Pignon, D.

    1983-07-01

    In this paper we give a theoretical analysis of the parity violation phenomena in nS - n'S transitions in atomic cesium induced by the electron-nucleus neutral-current interaction. The actual observation of parity violation consists in the measurement of an interference between the p.v. electric dipole amplitude Elpv with the electric amplitude induced by a static electric field. Our theoretical work must then include a calculation of the diagonal and non-diagonal polarizabilities of the states of atomic cesium. We have used a one-electron model proposed by Norcross which incorporates some many-body effects like the electric screening induced by the core polarization in a semi-empirical way. Our calculated values of the diagonal and non-diagonal polarizabilities of the nS states are in good agreement with the existing measurements; this confirms the already well-established success of the model in predicting the radiative transitions in cesium. We present theoretical arguments supported by detailed numerical computations showing that the one-particle matrix element of the parity-violating electron-nucleus interaction and the parity-violating electric dipole amplitude Elpv itself weakly depend on the shape of the one-electron potential provided the binding energies of the valence states are reproduced accurately. Furthermore it turns out that because of a compensation mechanism, the parity-violating transition is induced by the radiation field outside the ion core region where the screening can be described simply in terms of the measurable cesium ion polarizability. Our results are then used to extract, from the Ecole Normale Supérieure experiment, a value of the weak charge Qw = -57.1 ± 9.4 (r.m.s. statistical deviation) ± 4.7 (systematic uncertainty).

    The debate over the introduction of nuclear power in Australia has recently become more heated in light of safety concerns over the nuclear reactor meltdown emergency in Japan. Australia has also just committed to a carbon trading scheme to address its reliance on coal-fired energy and reduce greenhouse emissions. With 40% of the world's uranium located in Australia, the economic, environmental and health considerations are significant. This book contains an overview of global nuclear energy use and production, and presents a range of current opinions debating the pros and cons of Australia's

To account for mediations and passages made between an educational discourse fragment the international circulation, and Latin American local appropriations in recent history, in terms of continuities and ruptures (neoliberalism-postneoliberalism. Finally, in a third movement, we enunciate some reviews about the problematics between inclusive education and quality of education, given that the current public policy debates and both global and local levels are reduced to themes arising from the significant educational quality.

    In this paper we give a theoretical analysis of the parity violation phenomena in nS-n'S transitions in atomic cesium induced by the electron-nucleus neutral-current interaction. The actual observation of parity violation consists in the measurement of an interference between the p.v. electric dipole amplitude E/sub 1/sup(pv) with the electric amplitude induced by a static electric field. Our theoretical work must then include a calculation of the diagonal and non-diagonal polarizabilities of the states of atomic cesium. We have used a one-electron model proposed by Norcross which incorporates some many-body effects like the electric screening induced by the core polarization in a semi-empirical way. Our calculated values of the diagonal and non-diagonal polarizabilities of the nS states are in good agreement with the existing measurements; this confirms the already well-established success of the model in predicting the radiative transitions in cesium.

  14. The impact on CT dose of the variability in tube current modulation technology: a theoretical investigation

    Body CT scans are routinely performed using tube-current-modulation (TCM) technology. There is notable variability across CT manufacturers in terms of how TCM technology is implemented. Some manufacturers aim to provide uniform image noise across body regions and patient sizes, whereas others aim to provide lower noise for smaller patients. The purpose of this study was to conduct a theoretical investigation to understand how manufacturer-dependent TCM scheme affects organ dose, and to develop a generic approach for assessing organ dose across TCM schemes. The adult reference female extended cardiac-torso (XCAT) phantom was used for this study. A ray-tracing method was developed to calculate the attenuation of the phantom for a given projection angle based on phantom anatomy, CT system geometry, x-ray energy spectrum, and bowtie filter filtration. The tube current (mA) for a given projection angle was then calculated as a log-linear function of the attenuation along that projection. The slope of this function, termed modulation control strength, α, was varied from 0 to 1 to emulate the variability in TCM technology. Using a validated Monte Carlo program, organ dose was simulated for five α values (α = 0, 0.25, 0.5, 0.75, and 1) in the absence and presence of a realistic system mA limit. Organ dose was further normalized by volume-weighted CT dose index (CTDIvol) to obtain conversion factors (h factors) that are relatively independent of system specifics and scan parameters. For both chest and abdomen-pelvis scans and for 24 radiosensitive organs, organ dose conversion factors varied with α, following second-order polynomial equations. This result suggested the need for α-specific organ dose conversion factors (i.e., conversion factors specific to the modulation scheme used). On the other hand, across the full range of α values, organ dose in a TCM scan could be derived from the conversion factors established for a fixed-mA scan (hFIXED). This was possible by

    Several recent high profile failures in the UK health care system have promoted strong debate on compassion and care in nursing. A number of papers articulating a range of positions within this debate have been published in this journal over the past two and a half years. These articulate a diverse range of theoretical perspectives and have been drawn together here in an attempt to bring some coherence to the debate and provide an overview of the key arguments and positions taken by those involved. In doing this we invite the reader to consider their own position in relation to the issues raised and to consider the impact of this for their own practice. Finally the paper offers some sense of how individual practitioners might use their understanding of the debates to ensure delivery of good nursing care.

    This paper presents experimental and analytical investigations into the distribution of current around a through-edge crack located in an infinitely long cylindrical high temperature superconductor (HTS) on the basis of the Bean model. Current distributions around the crack in the HTS without deformation are obtained by a simple conformal mapping. It is shown that the current is singular at the tip of the crack. An intensity factor of the current is introduced to characterize the singularity, the order of which is equal to -1. Additionally, an experimental verification according to the trapped field distributions around the crack is carried out, and the experimental results show little difference with the theoretical analysis.

    The debate about cloning that took place 25 years ago, although directed toward a different sort of cloning, elucidates fundamental issues currently at stake in reproductive technologies and research. Paul Ramsey and Joseph Fletcher were participants in this early debate. The differences between Ramsey and Fletcher about the meaning and sufficiency of freedom, the understanding and weighing of good and evil, the connection between embodiment and personhood, the relationship of humans with nature, and the meaning of parenthood suggest both a broader agenda for the debate about cloning and a cautious move forward in the development of embryo-splitting.

    We designed acene molecules attached to two semi-infinite metallic electrodes to explore the source-drain current of graphene and the gate leakage current of the gate dielectric material in the field-effect transistors (FETs) device using the first-principles density functional theory combined with the non-equilibrium Green's function formalism. In the acene-based molecular junctions, we modify the connection position of the thiol group at one side, forming different electron transport routes. The electron transport routes besides the shortest one are defined as the cross channels. The simulation results indicate that electron transport through the cross channels is as efficient as that through the shortest one, since the conductance is weakly dependent on the distance. Thus, it is possible to connect the graphene with multiple leads, leading the graphene as a channel utilized in the graphene-based FETs in the mesoscopic system. When the conjugation of the cross channel is blocked, the junction conductance decreases dramatically. The differential conductance of the BA-1 is nearly 7 (54.57 μS) times as large as that of the BA-4 (7.35 μS) at zero bias. Therefore, the blocked graphene can be employed as the gate dielectric material in the top-gated graphene FET device, since the leakage current is small. The graphene-based field-effect transistors fabricated with a single layer of graphene as the channel and the blocked graphene as the gate dielectric material represent one way to overcome the problem of miniaturization which faces the new generation of transistors.

  4. A theoretical analysis to current exponent variation regularity and electromigration-induced failure

    Wang, Yuexing; Yao, Yao

    2017-02-01

    The electric current exponent, typically with j-n form, is a key parameter to predict electromigration-induced failure lifetime. It is experimentally observed that the current exponent depends on different damage mechanisms. In the current research, the physical mechanisms including void initiation, void growth, and joule heating effect are all taken into account to investigate the current exponent variation regularity. Furthermore, a physically based model to predict the mean time to failure is developed and the traditional Black's equation is improved with clear physical meaning. It is found that the solution to the resulting void initiation and growth equation yields a current exponent of 2 and 1, respectively. On the other hand, joule heating plays an important role in failure time prediction and will induce the current exponent n > 2 based on the traditional semi-empirical model. The predictions are in agreement with the experimental results.

    The electromagnetic field under applied AC and DC current in round and rectangularpipe was systematically investigated, then a concept of "equivalent current density"was proposed for evaluating the inhomogeneous electromagnetic pinch force, and themono-component removal efficiency and the overall removal efficiency of inclusionwere formulated. It is founded that flat pipe is superior to round pipe for the electro-magnetic removal of inclusion, and DC current can get a higher removal efficiencythan AC current due to absence of skin phenomenon. Under usual condition, a re-moval efficiency of 52% for 10μm inclusion or more than 92% for 20μm inclusioncan be achieved by imposing a current density of 3× 106A/m2 in a fiat pipe.

    Highlights: • Systematic theoretical methods in studies of equatorial ocean dynamics. • Linear wave-current interactions in stratified flows. • Exact solutions – Kelvin waves, azimuthal non-uniform currents. • Three-dimensional nonlinear currents. • Hamiltonian formulation for the governing equations and for structure-preserving/enhancing approximations. - Abstract: This essay is a commentary on the pivotal role of systematic theoretical methods in physical oceanography. At some level, there will always be a conflict between theory and experiment/data collection: Which is pre-eminent? Which should come first? This issue appears to be particularly marked in physical oceanography, to the extreme detriment of the development of the subject. It is our contention that the classical theory of fluids, coupled with methods from the theory of differential equations, can play a significant role in carrying the subject, and our understanding, forward. We outline the philosophy behind a systematic theoretical approach, highlighting some aspects of equatorial ocean dynamics where these methods have already been successful, paving the way for much more in the future and leading, we expect, to the better understanding of this and many other types of ocean flow. We believe that the ideas described here promise to reveal a rich and beautiful dynamical structure.

    Time-varying electromagnetic fields (EMF) can induce some physiological effects in neuronal tissues, which have been explored in many applications such as transcranial magnetic stimulation. Although transmembrane potentials and induced currents have already been the subjects of many theoretical studies, most previous works about this topic are mainly completed by utilizing Maxwell's equations, often by solving a Laplace equation. In previous studies, cells were often considered to be three-compartment models with different electroconductivities in different regions (three compartments are often intracellular regions, membrane, and extracellular regions). However, models like that did not take dynamic ion channels into consideration. Therefore, one cannot obtain concrete ionic current changes such as potassium current change or sodium current change by these models. The aim of the present work is to present a new and more detailed model for calculating transmembrane potentials and ionic currents induced by time-varying EMF. Equations used in the present paper originate from Nernst-Plank equations, which are ionic current-related equations. The main work is to calculate ionic current changes induced by EMF exposure, and then transmembrane potential changes are calculated with Hodgkin-Huxley model.

    Magnetic reconnection is an important physical process in various explosive phenomena in the universe. In the previous studies, it was found that fast re- connection takes place when the thickness of a current sheet becomes on the order of a microscopic length such as the ion larmor radius or the ion inertial length. In this study, we investigated the pinching process of a current sheet by the Lorentz force in a low-{\\beta} plasma using one-dimensional magnetohydrodynam- ics (MHD) simulations. It is known that there is an exact self-similar solution for this problem that neglects gas pressure. We compared the non-linear MHD dynamics with the analytic self-similar solution. From the MHD simulations, we found that with the gas pressure included the implosion process deviates from the analytic self-similar solution as t {\\rightarrow} t 0, where t 0 is the explosion time when the thickness of a current sheet of the analytic solution becomes 0. We also found a pair of MHD fast-mode shocks are generated and propaga...

    Free nucleons propagating in water are known to produce gamma rays, which form a background to the searches for diffuse supernova neutrinos and sterile neutrinos carried out with Cherenkov detectors. As a consequence, the process of nucleon knockout induced by neutral-current quasielastic interactions of atmospheric (anti)neutrinos with oxygen needs to be under control at the quantitative level in the background simulations of the ongoing and future experiments. In this paper, we provide a quantitative assessment of the uncertainty associated with the theoretical description of the nuclear cross sections, estimating it from the discrepancies between the predictions of different models.

    Understanding the folding of the human genome is a key challenge of modern structural biology. The emergence of chromatin conformation capture assays (e.g., Hi-C) has revolutionized chromosome biology and provided new insights into the three dimensional structure of the genome. The experimental data are highly complex and need to be analyzed with quantitative tools. It has been argued that the data obtained from Hi-C assays are consistent with a fractal organization of the genome. A key characteristic of the fractal globule is the lack of topological complexity (knotting or inter-linking). However, the absence of topological complexity contradicts results from polymer physics showing that the entanglement of long linear polymers in a confined volume increases rapidly with the length and with decreasing volume. In vivo and in vitro assays support this claim in some biological systems. We simulate knotted lattice polygons confined inside a sphere and demonstrate that their contact frequencies agree with the human Hi-C data. We conclude that the topological complexity of the human genome cannot be inferred from current Hi-C data.

Embryonic stem cells (ESCs and parthenogenic ESCs (pESCs are derived from the embryo proper while embryonic germ cells (EGCs, embryonal carcinoma cells (ECCs, and germ-line stem cells (GSC are produced from germ cells. ECCs were the first pluripotent stem cell lines established from adult testicular tumors while EGCs are generated in vitro from primordial germ cells (PGCs isolated in late embryonic development. More recently, studies have also demonstrated the ability to produce GSCs from adult germ cells, known as spermatogonial stem cells.

    Pluripotent stem cells have been derived from various embryonic, fetal and adult sources. Embryonic stem cells (ESCs) and parthenogenic ESCs (pESCs) are derived from the embryo proper while embryonic germ cells (EGCs), embryonal carcinoma cells (ECCs), and germ-line stem cells (GSC) are produced from germ cells. ECCs were the first pluripotent stem cell lines established from adult testicular tumors while EGCs are generated in vitro from primordial germ cells (PGCs) isolated in late embryonic development. More recently, studies have also demonstrated the ability to produce GSCs from adult germ cells, known as spermatogonial stem cells. Unlike ECCs, the source of GSCs are normal, non-cancerous adult tissue. The study of these unique cell lines has provided information that has led to the ability to reprogram somatic cells into an ESC-like state. These cells, called induced pluripotent stem cells (iPSCs), have been derived from a number of human fetal and adult origins.

    Are debatable scientific questions debatable? In 2000, the physicist-philosopher John Ziman posed this pithy—and crucial—question. He noted that scientists were at a disadvantage in public debate, because the rules of engagement are different in scientific discourse than in public discourse in ways that make it difficult for scientists to ‘win’ public arguments, even when the facts are on their side. In this paper, I revisit Ziman’s arguments in light of the difficulties that climate scientists have had in communicating the reality and gravity of global warming. In addition to the problem posed by Ziman, I also address the role of organized disinformation in further increasing the challenges that climate scientists face.

  19. Relationship between financial speculation and food prices or price volatility: applying the principles of evidence-based medicine to current debates in Germany.

    There is an unresolved debate about the potential effects of financial speculation on food prices and price volatility. Germany's largest financial institution and leading global investment bank recently decided to continue investing in agricultural commodities, stating that there is little empirical evidence to support the notion that the growth of agricultural-based financial products has caused price increases or volatility. The statement is supported by a recently published literature review, which concludes that financial speculation does not have an adverse effect on the functioning of the agricultural commodities market. As public health professionals concerned with global food insecurity, we have appraised the methodological quality of the review using a validated and reliable appraisal tool. The appraisal revealed major shortcomings in the methodological quality of the review. These were particularly related to intransparencies in the search strategy and in the selection/presentation of studies and findings; the neglect of the possibility of publication bias; a lack of objective or rigorous criteria for assessing the scientific quality of included studies and for the formulation of conclusions. Based on the results of our appraisal, we conclude that it is not justified to reject the hypothesis that financial speculation might have adverse effects on food prices/price volatility. We hope to initiate reflections about scientific standards beyond the boundaries of disciplines and call for high quality, rigorous systematic reviews on the effects of financial speculation on food prices or price volatility.

    Green grabbing is a scholarly critique of conservation efforts. Scholars of green grabbing argue that many conservation strategies - such as the designation of protected areas and the creation of market-based conservation mechanisms - are designed with the intent to dispossess local peoples...... and capitalise natural assets. First, to provide some context on the green grabbing debate, we discuss the trade-offs between conservation and development objectives. In addition, we refer briefly to the broader land grabbing debate of which green grabbing is a sub-component. Second, we question the theoretical...... foundations of green grabbing, the concepts of primitive accumulation and commodification of nature. Third, we compare data collected by the green grabbing scholars and conservation NGOs from the very same site in Madagascar. We conclude that rigorous post-intervention stakeholder analysis, rather than pre...

  1. Neurocognitive and Social Cognitive Approaches for Improving Functional Outcome in Early Psychosis: Theoretical Considerations and Current State of Evidence

    2012-01-01

    Full Text Available Improving functional outcome, in addition to alleviating psychotic symptoms, is now a major treatment objective in schizophrenia research. Given the large body of evidence suggesting pharmacological treatments generally have minimal effects on indices of functioning, research has turned to psychosocial rehabilitation programs. Among these, neurocognitive and social cognitive interventions are at the forefront of this field and are argued to target core deficits inherent to the schizophrenia illness. However, to date, research trials have primarily focused on chronic schizophrenia populations, neglecting the early psychosis groups who are often as severely impaired in social and occupational functioning. This theoretical paper will outline the rationale for investigating adjunctive cognitive-based interventions in the early phases of psychotic illness, critically examine the current approach strategies used in these interventions, and assess the evidence supporting certain training programs for improving functional outcome in early psychosis. Potential pathways for future research will be discussed.

    Full Text Available A devastating criticism of a "hard core" argumentation, stemming from skeptical authors, has strongly challenged an enthusiasm noticeable in most theoretical analyses of globalization, bringing to light many "darker sides" of the globalization phenomena. A detailed critical re-examination of their often unrealistic assumptions has presented a very serious challenge to globalists and has made room for the arising of the so called "great globalization debate", which has started over time to shape the mainstream of the contemporary social philosophy. In this paper we are closely looking into the way in which skeptics realize their devastating criticism of globalists' argumentation.

    The authors propose some reflections about the current debate related to the reduction of emissions induced by deforestation and forest degradation (REDD) in developing countries. The author comments the two possibilities about one of the issues in this debate: to decide whether this mechanism must be financed by means of mandatory markets or voluntary funds. She also comments the issue on the institutional framework: to integrate REDD implementation in the framework foreseen by Kyoto beyond 2012, or to integrate it in a distinct agreement or protocol. She discusses the variety of national specificities and expectations, and tries to identify perspectives.

  5. Auroral current systems in Saturn's magnetosphere: comparison of theoretical models with Cassini and HST observations

    Directory of Open Access Journals (Sweden)

    S. W. H. Cowley

    2008-09-01

    Full Text Available The first simultaneous observations of fields and plasmas in Saturn's high-latitude magnetosphere and UV images of the conjugate auroral oval were obtained by the Cassini spacecraft and the Hubble Space Telescope (HST in January 2007. These data have shown that the southern auroral oval near noon maps to the dayside cusp boundary between open and closed field lines, associated with a major layer of upward-directed field-aligned current (Bunce et al., 2008. The results thus support earlier theoretical discussion and quantitative modelling of magnetosphere-ionosphere coupling at Saturn (Cowley et al., 2004, that suggests the oval is produced by electron acceleration in the field-aligned current layer required by rotational flow shear between strongly sub-corotating flow on open field lines and near-corotating flow on closed field lines. Here we quantitatively compare these modelling results (the "CBO" model with the Cassini-HST data set. The comparison shows good qualitative agreement between model and data, the principal difference being that the model currents are too small by factors of about five, as determined from the magnetic perturbations observed by Cassini. This is suggested to be principally indicative of a more highly conducting summer southern ionosphere than was assumed in the CBO model. A revised model is therefore proposed in which the height-integrated ionospheric Pedersen conductivity is increased by a factor of four from 1 to 4 mho, together with more minor adjustments to the co-latitude of the boundary, the flow shear across it, the width of the current layer, and the properties of the source electrons. It is shown that the revised model agrees well with the combined Cassini-HST data, requiring downward acceleration of outer magnetosphere electrons through a ~10 kV potential in the current layer at the open-closed field line boundary to produce an auroral oval of ~1° width with UV emission intensities of a few tens of kR.

  6. Quantitative Myocardial Perfusion with Dynamic Contrast-Enhanced Imaging in MRI and CT: Theoretical Models and Current Implementation

    Directory of Open Access Journals (Sweden)

    G. J. Pelgrim

    2016-01-01

    Full Text Available Technological advances in magnetic resonance imaging (MRI and computed tomography (CT, including higher spatial and temporal resolution, have made the prospect of performing absolute myocardial perfusion quantification possible, previously only achievable with positron emission tomography (PET. This could facilitate integration of myocardial perfusion biomarkers into the current workup for coronary artery disease (CAD, as MRI and CT systems are more widely available than PET scanners. Cardiac PET scanning remains expensive and is restricted by the requirement of a nearby cyclotron. Clinical evidence is needed to demonstrate that MRI and CT have similar accuracy for myocardial perfusion quantification as PET. However, lack of standardization of acquisition protocols and tracer kinetic model selection complicates comparison between different studies and modalities. The aim of this overview is to provide insight into the different tracer kinetic models for quantitative myocardial perfusion analysis and to address typical implementation issues in MRI and CT. We compare different models based on their theoretical derivations and present the respective consequences for MRI and CT acquisition parameters, highlighting the interplay between tracer kinetic modeling and acquisition settings.

  8. Vitalism and the Darwin Debate

    Science.gov (United States)

    Henderson, James

    2012-08-01

    There are currently both scientific and public debates surrounding Darwinism. In the scientific debate, the details of evolution are in dispute, but not the central thesis of Darwin's theory; in the public debate, Darwinism itself is questioned. I concentrate on the public debate because of its direct impact on education in the United States. Some critics of Darwin advocate the teaching of intelligent design theory along with Darwin's theory, and others seek to eliminate even the mention of evolution from science classes altogether. Many of these critics base their objections on the claim that non-living matter cannot give rise to living matter. After considering some of the various meanings assigned to `vitalism' over the years, I argue that a considerable portion of Darwin deniers support a literal version of vitalism that is not scientifically respectable. Their position seems to be that since life cannot arise naturally, Darwin's theory accomplishes nothing: If it can only account for life forms changing from one to another (even this is disputed by some) but not how life arose in the first place, what's the point? I argue that there is every reason to believe that living and non-living matter differ only in degree, not in kind, and that all conversation about Darwinism should start with the assumption that abiogenesis is possible unless or until compelling evidence of its impossibility is presented. That is, I advocate a position that the burden of proof lies with those who claim "Life only comes from life." Until that case is made, little weight should be given to their position.

    There are active public campaigns both for and against homeopathy, and its continuing availability in the NHS is debated in the medical, scientific and popular press. However, there is a lack of clarity in key terms used in the debate, and in how the evidence base of homeopathy is described and interpreted. The term 'homeopathy' is used with several different meanings including: the therapeutic system, homeopathic medicine, treatment by a homeopath, and the principles of 'homeopathy'. Conclusions drawn from one of these aspects are often inappropriately applied to another aspect. In interpreting the homeopathy evidence it is important to understand that the existing clinical experimental (randomised controlled trial) evidence base provides evidence as to the efficacy of homeopathic medicines, but not the effectiveness of treatment by a homeopath. The observational evidence base provides evidence as to the effectiveness of treatment by a homeopath. We make four recommendations to promote clarity in the reporting, design and interpretation of homeopathy research.

    2016-09-01

    This essay is a commentary on the pivotal role of systematic theoretical methods in physical oceanography. At some level, there will always be a conflict between theory and experiment/data collection: Which is pre-eminent? Which should come first? This issue appears to be particularly marked in physical oceanography, to the extreme detriment of the development of the subject. It is our contention that the classical theory of fluids, coupled with methods from the theory of differential equations, can play a significant role in carrying the subject, and our understanding, forward. We outline the philosophy behind a systematic theoretical approach, highlighting some aspects of equatorial ocean dynamics where these methods have already been successful, paving the way for much more in the future and leading, we expect, to the better understanding of this and many other types of ocean flow. We believe that the ideas described here promise to reveal a rich and beautiful dynamical structure.

    1987-04-01

    Although the Strategic Defense Initiative (SDI) is meant to cope with the danger of a Soviet nuclear attack, the recent US debate over SDI has paid surprisingly little attention to Soviet views of ballistic missile defense. Despite the existence of a substantial body of pertinent scholarship, the debate has failed to take adequate account of major changes in Soviet ballistic missile defense policy since the mid-1960s. It has also neglected the links between current Soviet military policy and broader Soviet political and economic choices. The Soviets regard SDI not as a novel undertaking to reduce the risks of nuclear war but as an extension of the geopolitical competition between the superpowers. This competition has been dominated in the 1980s, in the Soviet view, by sharply increased US assertiveness and the decline of detente. Viewing SDI as a manifestation of these general trends, Soviet decision makers find the prospect of an unregulated race in ballistic missile defenses and military space technologies deeply unsettling. The deterioration of superpower relations has raised serious doubts in Moscow about the wisdom of Soviet external policy during the 1970s and has provoked sharp internal differences over policy toward the US. Already highly suspicious of the Reagan administration, the elite is united by a general conviction that SDI is an American gambit that may ultimately undercut past Soviet strategic gains and pose a grave new threat to Soviet security. 14 references.

    The authors compare the results of a microscopic laser theory with gain and recombination currents obtained from experimental spontaneous emission spectra. The calculated absorption spectrum is first matched to that measured on a laser, ensuring that the quasi-Fermi levels for the calculation and the experiment (spontaneous emission and gain) are directly related. This allows one to determine the inhomogeneous broadening in their experimental samples. The only other inputs to the theory are literature values of the bulk material parameter. The authors then estimate the non-radiative recombination current associated with the well and wave-guide core from a comparison of measured and calculated recombination currents.

    Highlights: •A combined experimental and theoretical approach was used for risk assessments of six BFRs in fish. •Oxidative stress biomarkers were measured for toxicity identification. •Toxicity order was proposed via the integrated biomarker response. •Theoretical calculations were performed to analyze the BFRs toxicity. -- Abstract: Decabromodiphenyl ether (BDE-209) and several non-polybrominated diphenyl ether (PBDE) brominated flame retardants (BFRs), such as tetrabromobisphenol A (TBBPA), hexabromocyclododecane (HBCD), decabromodiphenyl ethane (DBDPE), hexabromobenzene (HBB) and pentabromotoluene (PBT), are persistent halogenated contaminants ubiquitously detected in aquatic systems. However, data on comparative toxicological effects of these BFRs are lacking for fish. In this study, a combined experimental and theoretical approach was used to compare and analyze the effects of these BFRs on biochemical biomarkers in liver of Carassius auratus injected intraperitoneally with different doses (10 and 100 mg/kg) for 7, 14 and 30 days. Oxidative stress was evoked evidently for the prolonged exposure, represented by the significantly altered indices (superoxide dismutase, catalase, glutathione peroxidase, reduced glutathione, and malondialdehyde). The integrated biomarker response (IBR) index ranked biotoxicity as: PBT > HBB > HBCD > TBBPA > BDE-209 > DBDPE. Quantum chemical calculations (electronic parameters, frontier molecular orbitals, and Wiberg bond order) were performed for theoretical analysis. Notably, some descriptors were correlated with the toxicity order, probably implying the existence of a potential structure–activity relationship when more BFRs were included. Besides, theoretical calculations also provided some valuable information regarding the molecular characteristics and metabolic pathways of these current-use BFRs, which may facilitate the understanding on their environmental behavior and fate. Overall, this study adopted a combined

    This paper describes an investigation of the spontaneous emission limit to the laser threshold current density in an InGaN quantum well laser. The peak gain and spontaneous emission rate as functions of carrier density are com- puted using a microscopic laser theory. From these quantities, the minimum achievable threshold current density is determined for a given threshold gain. The dependence on quantum well width, and the effects of inhomogeneous broadening due to spatial alloy variations are discussed. Also, comparison with experiments is made.

  8. Theoretical Mathematics

    Stöltzner, Michael

    Answering to the double-faced influence of string theory on mathematical practice and rigour, the mathematical physicists Arthur Jaffe and Frank Quinn have contemplated the idea that there exists a `theoretical' mathematics (alongside `theoretical' physics) whose basic structures and results still require independent corroboration by mathematical proof. In this paper, I shall take the Jaffe-Quinn debate mainly as a problem of mathematical ontology and analyse it against the backdrop of two philosophical views that are appreciative towards informal mathematical development and conjectural results: Lakatos's methodology of proofs and refutations and John von Neumann's opportunistic reading of Hilbert's axiomatic method. The comparison of both approaches shows that mitigating Lakatos's falsificationism makes his insights about mathematical quasi-ontology more relevant to 20th century mathematics in which new structures are introduced by axiomatisation and not necessarily motivated by informal ancestors. The final section discusses the consequences of string theorists' claim to finality for the theory's mathematical make-up. I argue that ontological reductionism as advocated by particle physicists and the quest for mathematically deeper axioms do not necessarily lead to identical results.

  9. Theoretical and numerical analysis of current-driven electromagnetic homogenization and the problem of effective medium parameters for finite samples

    Markel, Vadim A

    2013-01-01

    Reflection and refraction of electromagnetic waves by artificial periodic composites (metamaterials) can be accurately modeled by an effective medium theory only if the boundary of the medium is explicitly taken into account and the two effective parameters of the medium -- the index of refraction and the impedance -- are correctly determined. Theories that consider infinite periodic composites do not satisfy the above condition. As a result, they cannot model reflection and transmission by finite samples with the desired accuracy and are not useful for design of metamaterial-based devices. As an instructive case in point, we consider the "current-driven" homogenization theory, which has recently gained popularity. We apply this theory to the case of one-dimensional periodic medium wherein both exact and homogenization results can be obtained analytically in closed form. We show that, beyond the well-understood zero-cell limit, the current-driven homogenization result is inconsistent with the exact reflection...

The first “natural” current sheet was discovered in flare spectrum, calculated and researched experimentally. The current sheets (CS are found in chromosphere and downward levels in optical range data. The main problem of physics of solar flares has been solved. Magnetic field energy is a primary source of active processes in solar plasma. Current sheet (CS of S. I. Syrovatskij is the mechanism of magnetic energy transformation into plasma energy. The current sheet is not discovered in a flare, as expected. As a matter of fact, solar flare is in itself a current sheet, its direct observed development in chromosphere plasma. Continuous current sheet radiation is the «black» (BLF and the «white» (WLF flare (like light of Sun photosphere.

    Full Text Available A new approach to the determination of the current distribution in electrochemical cells, the current line division concept, is introduced. The new concept, based on the basic equations of electrics and electrochemical kinetics, was employed for a theoretical explanation of the phenomenon known in electroforming as “corner weakness”. It was shown that this phenomenon depends on the kind of control of the deposition process, being the largest in the case of pure ohmic control and disappearing in the case of pure activation control.

  13. Beyond the mammography debate: a moderate perspective.

    Kaniklidis, C

    2015-06-01

    After some decades of contention, one can almost despair and conclude that (paraphrasing) "the mammography debate you will have with you always." Against that sentiment, in this review I argue, after reflecting on some of the major themes of this long-standing debate, that we must begin to move beyond the narrow borders of claim and counterclaim to seek consensus on what the balance of methodologically sound and critically appraised evidence demonstrates, and also to find overlooked underlying convergences; after acknowledging the reality of some residual and non-trivial harms from mammography, to promote effective strategies for harm mitigation; and to encourage deployment of new screening modalities that will render many of the issues and concerns in the debate obsolete. To these ends, I provide a sketch of what this looking forward and beyond the current debate might look like, leveraging advantages from abbreviated breast magnetic resonance imaging technologies (such as the ultrafast and twist protocols) and from digital breast tomosynthesis-also known as three-dimensional mammography. I also locate the debate within the broader context of mammography in the real world as it plays out not for the disputants, but for the stakeholders themselves: the screening-eligible patients and the physicians in the front lines who are charged with enabling both the acts of screening and the facts of screening at their maximally objective and patient-accessible levels to facilitate informed decisions.

    Full Text Available Las perspectivas que ofrece la teoría del reconocimiento para comprender las transformaciones que vienen sucediéndose de modo acelerado en las sociedades contemporáneas se han convertido en un eje de debate en la filosofía social y política. En particular se examinan algunas de las propuestas teóricas que parten de la consideración del sentido antropológico del reconocimiento y su relectura desde la definición que tiene en la cultura moderna, en pensadores como Rousseau y Hegel, para ofrecer diferentes claves de interpretación de los procesos de cambio social que han ido produciéndose en la actualidad. Una de las opciones analizadas se vincula con el filósofo frankfurtiano Axel Honneth, quien ha desarrollado un conjunto de tesis acerca de la relevancia del reconocimiento recíproco en relación a las dinámicas que movilizan los conflictos sociales. Además de la necesidad de contrastar este planteo con otros enfoques contemporáneos, se revisan algunos supuestos y alcances de la teoría del reconocimiento desde una perspectiva crítica que se contextualiza en el marco de las transformaciones producidas con la globalización y la crisis reciente que atraviesan las sociedades capitalistas. Desde este punto de vista, interesa indagar sobre la significación de las manifestaciones alternativas de los movimientos sociales en sus formas novedosas de protesta y reclamo de justicia. En este sentido, se ensayan algunos lineamientos en torno a las políticas del reconocimiento, en cuanto esta discusión implica una evaluación de la igualdad y la diferencia como principios normativos y orientadores de los cambios materiales y culturales que se presentan en el mundo actual.The perspectives provided by the recognition theory to understand the transformations that have been happening in contemporary societies, have swiftly turned into a focus of discussion in social and political philosophy.

  15. The euthanasia debate.

    Harris, N M

    2001-10-01

    Debates about the moral dilemmas of euthanasia date back to ancient times. Many of the historical arguments used for and against the practice remain valid today. Indeed, any form of discussion on the subject often provokes emotive responses, both from members of the medical profession and the general public. For this reason alone, the issue will continue to be debated at all levels of society. There are, however, other factors that ensure euthanasia will remain a subject of major controversy within medical, legal and governmental bodies. Firstly, the act of euthanasia itself is illegal, yet in its passive form occurs on a daily basis in many of our hospitals (1). Secondly, medical advances have made it possible to artificially prolong the life of an increasing number of patients far beyond what was possible only a few years ago. Furthermore, we must all contend with the reality that financial constraints are an important consideration in modern health care provision. Finally, there is an ethical difficulty in interpreting the concept of a patient's right, or autonomy, versus the rights and duty of a doctor. Before attempting to answer the questions posed by these issues, it is important to have some accurate definitions of both euthanasia and of the concept of morality. According to the House of Lords Select Committee on Medical Ethics, the precise definition of euthanasia is "a deliberate intervention undertaken with the express intention of ending a life, to relieve intractable suffering" (2). The term can be further divided into voluntary and involuntary euthanasia. The former is said to occur if a competent patient makes an informed request for a life terminating event and the latter can be used if a patient does not give informed and specific consent for such treatment. It is the occurrence of involuntary euthanasia which forms one of the main arguments against legalisation. This is discussed in greater detail below. Euthanasia is frequently separated into

    There exists a current crowding effect in the anode of A1GaN/GaN heteto junction Schottky diodes, causing local overheating when working at high power density, and undermining their performance. The seriousness of this effect is illustrated by theoretical analysis. A method of reducing this effect is proposed by depositing a polysilicon layer on the Schottky barrier metal. The effectiveness of this method is provided through computer simulation.Power consumption of the polysilicon layer is also calculated and compared to that of the Schottky junction to ensure the applicability of this method.

    Kirchhoff's law was used to examine the electrical specifications of selection diodes, which are essential for suppressing the read interference problems in nano-scale resistive switching cross bar arrays with a high block density. The diode in the cross bar array with a 100 Mb block density should have a reverse/forward resistance ratio of > 108, and a forward current density of > 105 A cm - 2 for stable reading and writing operation. Whilst normal circuit simulators are heavily overloaded when the number of cells (m) connected to one bit and word line is larger (m\\gg 100 ), which is the desired range for high density cross bar arrays, the present model can provide a simple simulation. The validity of this new method was confirmed by a comparison with the previously reported method based on a voltage estimation.

    2015-12-01

    Nine original articles comprise this special issue of the Journal of Personality addressing personality-based perspectives of psychopathy. In this introduction to the special issue, we review five advances and areas of agreement that are highlighted across the articles, including the utility of trait perspectives to psychopathy, the emergence of a prototypical trait profile of psychopathy, the importance of recognizing earlier developmental manifestations of psychopathy, the ongoing study and revelation of the basic neural underpinnings of psychopathy, and the important theoretical and empirical association between psychopathy and antisocial behavior. At the same time, several important debates remain, which are also highlighted in the special issue's articles. These debates center around the necessity and sufficiency of certain psychopathy traits, the role of traits alternatively labeled stable Extraversion, fearless dominance, or boldness, and the validity and utility of separating psychopathy from Machiavellianism as is done in research on the Dark Triad.

    Full Text Available Relying primarily on the Common European Framework of Reference for Languages (CEFR and The National EFL Syllabus, this paper focuses on the highest ranking goals within formal foreign language (L2 education: the development of communicative competence (which the communicative paradigm regards as the most important goal of contemporary language teaching, and of critical thinking (CT ability, which is widely recognised as the main general education goal. It also points to some of the discrepancies generated by tensions between the fact that language is a social and cultural phenomenon that exists and evolves only through interaction with others, and individual-student-centred pedagogical practices of teaching (and assessment – which jeopardise the validity of these practices. Next, it links the official educational goals to the cultivation of oral interaction (rather than oral production in argumentative discursive practices in general and in structured debate formats in particular, which are proposed as an effective pedagogical method for developing CT skills and oral interactional competence in argumentative discursive events, especially on B2+ levels.

    2002-12-01

    From 1954 to 1963, numerous scientists engaged in a public debate over the possible hazards from radioactive fallout from nuclear weapons testing. Nobel laureate Linus Pauling, a California Institute of Technology chemist, was one of the most prominent. His scientific papers relating to the fallout debate reveal many of the scientific, social and political issues involved in the controversy. Although the public controversy ended after the signing of the 1963 Limited Test Ban Treaty, many of the scientific questions about the possible hazards of low-level radiation remain under debate within the scientific community. Moreover, the fallout debate was a prototype of current controversies over environmental and public-health hazards.

    One studied both theoretically and experimentally the Cherenkov superradiance at liner motion of an electron bunch through the periodic slowing down system. Simulations in terms of the KARAT code show that peak intensity of microwave pulses is proportional to the square of total number of particles in a bunch. This finding os conformed experimentally. As a results, at 39 GHz frequency one obtained ultrashort pulses of up to 140 MW high intensity and with 30 ps duration. The RADAN 303 high-current subnanosecond accelerator injected electron bunches with up to 2 A current, 0.5-1.5 ns duration and 200-300 keV particle energy was used as a source of electrons. Simulation shows possibility of further intensification of electromagnetic pulses up to 300-400 MW due to optimization of parameters of accelerating voltage pulse

    2007-05-01

    The present interdisciplinary brain-mind debate with regard to neurobiology shows deficits in the criticism of methods and in the precision of language and argumentation. Simplifying localisations of psychic functions, insufficient explanations and over-interpretations in the sense of physical determinism are the consequence. This can be demonstrated in deficits of neurobiological theories of volitional action. Therefore, the current concept of man is less perturbed than is proposed by neurobiologists. For psychiatry besides the neurobiological approach also a separate way of building models seems to be useful if present theoretical psychology and systems science would be regarded. In particular, the systems science of natural systems offers new opportunities to bridge gaps between disciplines involved in the brain-mind debate.

  13. Abortion: taking the debate seriously.

    Kottow Lang, Miguel Hugo

    2015-05-19

    Voluntarily induced abortion has been under permanent dispute and legal regulations, because societies invariably condemn extramarital pregnancies. In recent decades, a measure of societal tolerance has led to decriminalize and legalize abortion in accordance with one of two models: a more restricted and conservative model known as therapeutic abortion, and the model that accepts voluntary abortion within the first trimester of pregnancy. Liberalization of abortion aims at ending clandestine abortions and decriminalizes the practice in order to increase reproductive education and accessibility of contraceptive methods, dissuade women from interrupting their pregnancy and, ultimately, make abortion a medically safe procedure within the boundaries of the law, inspired by efforts to reduce the incidence of this practice. The current legal initiative to decriminalize abortion in Chile proposes a notably rigid set of indications which would not resolve the three main objectives that need to be considered: 1) Establish the legal framework of abortion; 2) Contribute to reduce social unrest; 3) Solve the public health issue of clandestine, illegal abortions. Debate must urgently be opened to include alternatives in line with the general tendency to respect women's decision within the first trimester of pregnancy.

    This paper revisits the debate about cognitive phenomenology. It elaborates, defends, and improves on our earlier proposal for resolving that debate, according to which the test for irreducible phenomenology is the presence of explanatory gaps. After showing how proposals like ours have been misunderstood or misused by others, we deploy our operationalization to argue that the correct way to align the debate over cognitive phenomenology is not between sensory and (alleged) cognitive phenomenology, but rather between non-conceptual and (alleged) conceptual or propositional phenomenology. In doing so we defend three varieties of non-sensory (amodal)(1) non-conceptual phenomenology: valence, a sense of approximate number, and a sense of elapsed time. Copyright © 2017 Elsevier Inc.

Throughout the presentations and subsequent debates, whenever the different participants referred to aspects of the cultural identity problematic--”angst”, “obsession”, “deficit”, manipulation”, and others, these same participants in the Transversal Lines of the Debates also showed that, in certain areas, an optimistic viewpoint is not out of the question.

    In the present paper, theoretic investigations of polarisation vector precession trajectories represented by a macro spin in ferromagnetic films with in-plane uniaxial anisotropy were realised. For this purpose, the Landau-Lifschitz-Gilbert differential equation (LLG) in combination with the Maxwell equations were solved for three dimensions by considering a linear progression of the magnetisation or polarisation with an external field. The frequency and time dependent polarisation trajectories illustrate how a magnetic moment precesses if effective damping and eddy-currents impacts its motion. For computation, typical parameter values like the saturation polarisation J{sub s}={mu}{sub 0}{center_dot}M{sub s}=1.4 T and in-plane uniaxial anisotropy {mu}{sub 0}{center_dot}H{sub u}=4.5 mT were employed. The main focus of simulation was on the variation of the effective damping parameter {alpha}{sub eff} between 0.01 and 0.05 and ferromagnetic film thickness t{sub m} between 200 nm and 1200 nm. The frequency-dependent calculations were carried out between 50 MHz and 6 GHz. The time-dependent simulations were done for a duration between 5 and 30 ns. - Highlights: Black-Right-Pointing-Pointer Frequency- and time domain solution of the LLG and Maxwell differential equation.

  11. Debating the role of econophysics.

    Science.gov (United States)

    Rosser, J Barkley

    2008-07-01

    Research in econophysics has been going on for more than a decade with considerable publicity in some of the leading general science journals. Strong claims have been made by some advocates regarding its reputed superiority to economics, with arguments that in fact the teaching of microeconomics and macroeconomics as they are currently constituted should cease and be replaced by appropriate courses in mathematics, physics, and some other harder sciences. The lack of invariance principles in economics and the failure of economists to deal properly with certain empirical regularities are held against it in this line of argument. Responding arguments address four points: (a) that many econophysicists lack awareness of what has been done in economics and thus sometimes claim a greater degree of originality and innovativeness in their work than is deserved, (b) that econophysicists do not use as sufficiently rigorous or sophisticated statistical methodology as econometricians, (c) that econophysicists search for universal empirical regularities in economics that probably do not exist, and (d) that the theoretical models they adduce to explain empirical phenomena have many difficulties and limits. This article examines the arguments and concludes that nonlinear dynamics and entropy concepts may provide a productive way forward.

  13. A Computational Model of Self-Efficacy's Various Effects on Performance: Moving the Debate Forward.

    Science.gov (United States)

    Vancouver, Jeffrey B; Purl, Justin D

    2016-12-19

    Self-efficacy, which is one's belief in one's capacity, has been found to both positively and negatively influence effort and performance. The reasons for these different effects have been a major topic of debate among social-cognitive and perceptual control theorists. In particular, the findings of various self-efficacy effects has been motivated by a perceptual control theory view of self-regulation that social-cognitive theorists' question. To provide more clarity to the theoretical arguments, a computational model of the multiple processes presumed to create the positive, negative, and null effects for self-efficacy is presented. Building on an existing computational model of goal choice that produces a positive effect for self-efficacy, the current article adds a symbolic processing structure used during goal striving that explains the negative self-efficacy effect observed in recent studies. Moreover, the multiple processes, operating together, allow the model to recreate the various effects found in a published study of feedback ambiguity's moderating role on the self-efficacy to performance relationship (Schmidt & DeShon, 2010). Discussion focuses on the implications of the model for the self-efficacy debate, alternative computational models, the overlap between control theory and social-cognitive theory explanations, the value of using computational models for resolving theoretical disputes, and future research and directions the model inspires.

  14. What controls open-pore and residual currents in the first sensing zone of alpha-hemolysin nanopore? Combined experimental and theoretical study

    The electrophoretic transport of single-stranded DNA through biological nanopores such as alpha-hemolysin (αHL) is a promising and cost-effective technology with the potential to revolutionize genomics. The rational design of pores with the controlled polymer translocation rates and high contrast between different nucleotides could improve significantly nanopore sequencing applications. Here, we apply a combination of theoretical and experimental methods in an attempt to elucidate several selective modifications in the pore which were proposed to be central for the effective discrimination between purines and pyrimidines. Our nanopore test set includes the wild type αHL and six mutants (E111N/M113X/K147N) in which the cross-section and chemical functionality of the first constriction zone of the pore are modified. Electrophysiological recordings were combined with all-atom Molecular Dynamics simulations (MD) and a recently developed Brownian Dynamics (BROMOC) protocol to investigate residual ion currents and pore-DNA interactions for two homo-polymers e.g. poly(dA)40 or poly(dC)40 blocking the pore. The calculated residual currents and contrast in the poly(dA)40/poly(dC)40 blocked pore are in qualitative agreement with the experimental recordings. We showed that a simple structural metric allows rationalization of key elements in the emergent contrast between purines and pyrimidines in the modified αHL mutants. The shape of the pore and its capacity for hydrogen bonding to a translocated polynucleotide are two essential parameters for contrast optimization. To further probe the impact of these two factors in the ssDNA sensing, we eliminated the effect of the primary constriction using serine substitutions (i.e. E111S/M113S/T145S/K147S) and increased the hydrophobic volume of the central residue in the secondary constriction (L135I). This pore modification sharply increased the contrast between Adenine (A) and Cytosine (C).The electrophoretic transport of single

More generally, the word globalization is usually used to indicate a unified world that tends to homogenize products and consumption patterns. In addition to the undoubtedly positive effects that the processes of globalization have on the overall well-being and the possibilities of consumption in all countries, a lively debate has developed among economists, but also among philosophers, sociologists and other scholars...

  16. BEHAVIORAL INPUTS TO THE THEORETICAL APPROACH OF THE ECONOMIC CRISIS

    Directory of Open Access Journals (Sweden)

    Sinziana BALTATESCU

    2015-09-01

    Full Text Available The current economic and financial crisis gave room for the theoretical debates to reemerge. The economic reality challenged the mainstream neoclassical approach leaving the opportunity for the Austrian School, Post Keynesianism or Institutionalists to bring in front theories that seem to better explain the economic crisis and thus, leaving space for more efficient economic policies to result. In this context, the main assumptions of the mainstream theoretical approach are challenged and reevaluated, behavioral economics is one of the main challengers. Without developing in an integrated school of thought yet, behavioral economics brings new elements within the framework of economic thinking. How are the main theoretical approaches integrating these new elements and whether this process is going to narrow the theory or enrich it to be more comprehensive are questions to which this paper tries to answer, or, at least, to leave room for an answer.

Firstly, it points out the drawbacks and weaknesses of the 1st and 2nd phases of the development of this discipline, namely the positivist and non-positivist characteristic of influence study, and the lack of a "world mind" in parallel study by claiming that there's no comparability between different cultures. Secondly, the cultural diversity should be highlighted as comparability since we should not only seek the common ground but also pay attention to the differences. The variation theory in eomparative literature raised by the present author can help complete the theoretical system of comparative literature. Thirdly, this artiele points out that eom- parative literature will enter the phase of world literature, in which Chinese scholars will play an important role.

  19. Designing for students' science learning using argumentation and classroom debate

    Science.gov (United States)

    Bell, Philip Laverne

    1998-12-01

    This research investigates how to design and introduce an educational innovation into a classroom setting to support learning. The research yields cognitive design principles for instruction involving scientific argumentation and debate. Specifically, eighth-grade students used a computer learning environment to construct scientific arguments and to participate in a classroom debate. The instruction was designed to help students integrate their science understanding by debating: How far does light go, does light die out over distance or go forever until absorbed? This research explores the tension between focusing students' conceptual change on specific scientific phenomena and their development of integrated understanding. I focus on the importance of connecting students' everyday experiences and intuitions to their science learning. The work reported here characterizes how students see the world through a filter of their own understanding. It explores how individual and social mechanisms in instruction support students as they expand the range of ideas under consideration and distinguish between these ideas using scientific criteria. Instruction supported students as they engaged in argumentation and debate on a set of multimedia evidence items from the World-Wide-Web. An argument editor called SenseMaker was designed and studied with the intent of making individual and group thinking visible during instruction. Over multiple classroom trials, different student cohorts were increasingly supported in scientific argumentation involving systematic coordination of evidence with theoretical ideas about light. Students' knowledge representations were used as mediating "learning artifacts" during classroom debate. Two argumentation conditions were investigated. The Full Scope group prepared to defend either theoretical position in the debate. These students created arguments that included more theoretical conjectures and made more conceptual progress in understanding

  20. Affordances and Constraints of Using the Socio-Political Debate for Authentic Summative Assessment

    Anker-Hansen, Jens; Andrée, Maria

    2015-10-01

    This article reports from an empirical study on the affordances and constraints for using staged socio-political debates for authentic summative assessment of scientific literacy. The article focuses on conditions for student participation and what purposes emerge in student interaction in a socio-political debate. As part of the research project, a socio-political debate was designed for assessing student competences of scientific literacy in classroom practices. The debate centred on a fictive case about a lake where a decline in the yield of fish had been established. The students were assigned the task of participating in the debate from appointed roles as different stakeholders. Data were collected with video recordings of the enacted student debates. Student participation was analysed with the theoretical framework of communities of practice. The results show that multiple conflicting purposes of the socio-political debate as an assessment task emerged. The emergent purposes were (1) putting scientific knowledge on display versus staying true to one's role, (2) putting scientific knowledge on display versus expressing social responsibility, (3) putting scientific knowledge on display versus winning the debate, and (4) using sources tactically versus using sources critically. As these purposes emerged in classroom practice, tensions between different ways of enacting participation in the debates became manifest. Based on these findings, this article discusses the affordances and constraints for using a socio-political debate for classroom-based assessment of scientific literacy and argumentation in terms of validity, reliability and affordability.

Muddying the ensuing policy debate was the use of buzzwords, like mainstream, deviant, assimilated, minority, black matriarch, absent father, and underclass, that were themselves categorizing and hierarchical. The tautology of hierarchically labeling groups and then asking why groups with different labels have different outcomes seems to be perpetually invisible to the parties in the assimilation debate, but the debate itself rages on. Newer scholarship has added a different voice to that debate, arguing that variance in "assimilation" is instead explained by incorporation into

  3. Dry needling versus acupuncture: the ongoing debate.

    Zhou, Kehua; Ma, Yan; Brogan, Michael S

    2015-12-01

    Although Western medical acupuncture (WMA) is commonly practised in the UK, a particular approach called dry needling (DN) is becoming increasingly popular in other countries. The legitimacy of the use of DN by conventional non-physician healthcare professionals is questioned by acupuncturists. This article describes the ongoing debate over the practice of DN between physical therapists and acupuncturists, with a particular emphasis on the USA. DN and acupuncture share many similarities but may differ in certain aspects. Currently, little information is available from the literature regarding the relationship between the two needling techniques. Through reviewing their origins, theory, and practice, we found that DN and acupuncture overlap in terms of needling technique with solid filiform needles as well as some fundamental theories. Both WMA and DN are based on modern biomedical understandings of the human body, although DN arguably represents only one subcategory of WMA. The increasing volume of research into needling therapy explains its growing popularity in the musculoskeletal field including sports medicine. To resolve the debate over DN practice, we call for the establishment of a regulatory body to accredit DN courses and a formal, comprehensive educational component and training for healthcare professionals who are not physicians or acupuncturists. Because of the close relationship between DN and acupuncture, collaboration rather than dispute between acupuncturists and other healthcare professionals should be encouraged with respect to education, research, and practice for the benefit of patients with musculoskeletal conditions who require needling therapy.

  10. [The debate over drug legalization].

    Science.gov (United States)

    Babín Vich, Francisco de Asís

    2013-01-01

    The debate over drug legalization appears frequently in the media as a potential solution to issues such as drug trafficking and other problems related to drug use. In Spain, private consumption or even the production of small quantities of certain plants, whose active ingredients are considered illegal drugs, if clearly for own consumption are not practices criminalized by any law. In addition, a drug addict is considered a person who is ill. Although it has not always been like that even in the countries that have called for this debate, where at times the law prosecutes consumers. The population of our country, according to the views expressed in the opinion polls, prefer to increase preventive measures, foster the treatment freely assumed by drug addicts and make stricter the repression on drug trafficking. Therefore, when speaking of "legalization" we should be scrupulous with the semantics; legalize and decriminalize are not the same, it is not the same decriminalize consumption than decriminalize trafficking, neither is the same decriminalize private consumption than public consumption. Decriminalize private consumption is a fact in our country. Beyond this, we advocate for the strict need to analyze from a scientific perspective the hypothetical benefits that would result from drug legalization. Certainly, from the public health perspective, they are hard to find. We believe that the same logic applied to tobacco, increasing the restrictions on its use, is the path to follow with any addictive substance.

    2016-01-01

    Public debates are a common platform for presenting and juxtaposing diverging views on important issues. In this work we propose a methodology for tracking how ideas flow between participants throughout a debate. We use this approach in a case study of Oxford-style debates---a competitive format where the winner is determined by audience votes---and show how the outcome of a debate depends on aspects of conversational flow. In particular, we find that winners tend to make better use of a debate's interactive component than losers, by actively pursuing their opponents' points rather than promoting their own ideas over the course of the conversation.

  12. The debate over robotics in benign gynecology.

    Science.gov (United States)

    Rardin, Charles R

    2014-05-01

    The debate over the role of the da Vinci surgical robotic platform in benign gynecology is raging with increasing fervor and, as product liability issues arise, greater financial stakes. Although the best currently available science suggests that, in the hands of experts, robotics offers little in surgical advantage over laparoscopy, at increased expense, the observed decrease in laparotomy for hysterectomy is almost certainly, at least in part, attributable to the availability of the robot. In this author's opinion, the issue is not whether the robot has any role but rather to define the role in an institutional environment that also supports the safe use of vaginal and laparoscopic approaches in an integrated minimally invasive surgery program. Programs engaging robotic surgery should have a clear and self-determined regulatory process and should resist pressures in place that may preferentially support robotics over other forms of minimally invasive surgery.

    Tirado-Otálvaro, Andrés Felipe

    2016-07-21

    This article addresses illegal drug use within the current debate in traditional public health and in proposals from Latin America, while emphasizing the need to approach the issue from an alternative public health perspective centered on individual users, groups, and social movements as protagonists. This counterhegemonic approach thus aims to orient the discussion on the need for inclusive and democratic public policies. Illegal drug use has been addressed from various perspectives: clinical medicine, viewing it as a problem that generates mental disorders and infectious diseases, both through risky sexual practices and/or use of injecting paraphernalia; from a legal perspective, as a problem related to delinquency; and according to traditional public health, as a problem that generates school dropout and work absenteeism and increases the demand on health services, in addition to increasing violence and death. However, not all forms of drug consumption involve problematic use, nor do they all trigger disorders related to substance use.

    Quattrociocchi, Walter; Scala, Antonio

    2013-01-01

    The information system (T.V., newspapers, blogs, social network platforms) and its inner dynamics play a fundamental role on the evolution of collective debates and thus on the public opinion. In this work we address such a process focusing on how the current inner strategies of the information system (competition, customer satisfaction) once combined with the gossip may affect the opinions dynamics. A reinforcement effect is particularly evident in the social network platforms where several and incompatible cultures coexist (e.g, pro or against the existence of chemical trails and reptilians, the new world order conspiracy and so forth). We introduce a computational model of opinion dynamics which accounts for the coexistence of media and gossip as separated but interdependent mechanisms influencing the opinions evolution. Individuals may change their opinions under the contemporary pressure of the information supplied by the media and the opinions of their social contacts. We stress the effect of the media ...

  15. The ethics of algorithms: Mapping the debate

    Directory of Open Access Journals (Sweden)

    Brent Daniel Mittelstadt

    2016-11-01

    Full Text Available In information societies, operations, decisions and choices previously left to humans are increasingly delegated to algorithms, which may advise, if not decide, about how data should be interpreted and what actions should be taken as a result. More and more often, algorithms mediate social processes, business transactions, governmental decisions, and how we perceive, understand, and interact among ourselves and with the environment. Gaps between the design and operation of algorithms and our understanding of their ethical implications can have severe consequences affecting individuals as well as groups and whole societies. This paper makes three contributions to clarify the ethical importance of algorithmic mediation. It provides a prescriptive map to organise the debate. It reviews the current discussion of ethical aspects of algorithms. And it assesses the available literature in order to identify areas requiring further work to develop the ethics of algorithms.

    2001-02-01

    The question of whether a fetus can experience pain is an immense challenge. The issue demands consideration of the physical and psychological basis of being and the relation between the two. At the center of this debate is the question of how it is that we are conscious, a question that has inspired the writing of some of our most brilliant contemporary philosophers and scientists, with one commentary suggesting surrender. In my earlier review I attempted to draw together the various strands of thinking that had attacked the question of fetal pain and relate them back to the bigger question of consciousness. In their vituperative response, Benatar and Benatar bite off my finger before looking to where I am pointing. I will examine each of their criticisms.

    Nuyen, A T

    2000-01-01

    The philosophers' tendency to characterize euthanasia in terms of either the right or the responsibility to die is, in some ways, problematic. Stepping outside of the analytic framework, the author draws out the implications of the ethics of Emmanuel Levinas for the euthanasia debate, tracing the ways Levinas' position differs not only from the philosophical consensus but also from the theological one. The article shows that, according to Levinas, there is no ethical case for suicide or assisted suicide. Death cannot be assumed or chosen--not only because suicide is a logically and metaphysically contradictory concept but also because in the choice of death ethical responsibility turns into irresponsibility. However, since Levinas holds that one must be responsible to the point of expiation, he can be said to approve certain actions that may have the consequence of hastening death.

  1. [The climate debate: the facts].

    2009-01-01

    The first report by the Intergovernmental Panel on Climate Change (IPCC) appeared almost 20 years ago. Environmental contamination has a negative effect on the environment in which we live. However, the public at large is confused about the ins and outs of climate change. Managers, politicians, various kinds of advisors, scientists, so-called experts, sceptics and journalists have all taken it upon themselves to lead the debate. Whose task is it to ensure a sound discussion? Surely it is the IPCC's task. However, most politicians and many journalists, and even many scientists, do not take the trouble to read the entire IPCC report or parts of it. As a consequence, much nonsense is published and broadcast. An effective procedure to deal with the climate problem starts with a fair discussion of the scientific evidence. My advice is: just read the free IPCC report: http://www.ipcc.ch/ and click on 'WG I The Physical Science Basis'.

  2. Debatable Premises in Telecom Policy

    2015-01-01

    Around the world, telecommunications policy is one of the most important areas of public policy. The modern economy is driven by telecom technologies, and many telecom-related firms – Google, Apple, Facebook, and myriad fixed and mobile Internet service providers – are among the largest companies...... in the world. The Internet is opening up new platforms for business, education, government, and civic engagement. It has literally been a driving force in toppling governments. Telecommunications policy is important to every government in the world, and debates over what policies should be implemented......‟t stand up well to critical analysis. This paper collects and responds to a number of these premises that, collectively, underlie much popular, political, and academic support for increased telecommunications regulation in the United States and Europe – as well as much of the rest of the world....

  3. The ANWR debate rages on

    2001-03-26

    Americans opposed to drilling in the Arctic National Wildlife Refuge (ANWR) have scored a victory this week by succeeding to convince 55 members of Congress to oppose inclusion of future revenues from Arctic drilling, an item very dear to the heart of U.S. President George W. Bush. In their letter to Congressional Committee Chairman Nussle the members of Congress argued that that 'inclusion in the budget of the projected revenues would sacrifice the untrammeled and pristine nature of this existing wilderness for a limited supply of oil and an increase in federal receipts of an estimated $1.2 billion by 2004'. The offending budget item was subsequently removed from the draft budget before Congress. The debate over oil exploration in the ANWR has generated emotional volleys on both sides, exemplifying how differently political battles are fought in the United States, with powerful lobbyists with limitless funds on one side and well-organized grassroots movements mobilizing on the other. At the same time, apparently little attention is paid to the views of Alaska's native people who make up 16 per cent of the state's population. In Canada, oil and gas development in the Yukon and Northwest Territories is championed by prominent native leaders as well as by political leaders. It is also supported by Canadians at large. The official Canadian position is that ANWR should retain its protected status; the long-standing agreement that each country will consult with the other before drilling in the Arctic, should also remain in force. With both President Bush and Vice-President Cheney eager proponents of exploration in the wildlife refuge, expert opinion is that the debate over the ANWR will heat up again during the summer.

    Currently, in Copenhagen streets as in many other European cities an increasing diversity in the style of clothing which appeals to believing and fashion conscious Muslim women can be observed. These styles I loosely term Islamic fashion, i.e. a style of clothing that seeks to appear attractive...... and at the same time to match an Islamic moral code or aesthetics. In a Danish context, I argue, these disagreements have a bearing on strategies of Muslim women in terms of relations vis-à-vis the non-Muslim majority population. The debate among Muslims is seconded by a media debate on Islam and again like...

  6. A philosophical analysis of the evidence-based medicine debate

    2003-07-01

    Full Text Available Abstract Background The term "evidence-based medicine" (or EBM was introduced about ten years ago, and there has been considerable debate about the value of EBM. However, this debate has sometimes been obscured by a lack of conceptual clarity concerning the nature and status of EBM. Discussion First, we note that EBM proponents have obscured the current debate by defining EBM in an overly broad, indeed almost vacuous, manner; we offer a clearer account of EBM and its relation to the alternative approaches to medicine. Second, while EBM proponents commonly cite the philosophical work of Thomas Kuhn and claim that EBM is a Kuhnian 'paradigm shift,' we argue that such claims are seriously mistaken and unduly polarize the EBM debate. Third, we suggest that it is much more fruitful to understand the relationship between EBM and its alternatives in light of a different philosophical metaphor: W.V. Quine's metaphor of the web of belief. Seen in this way, we argue that EBM is an approach to medical practice that is indeed importantly different from the alternatives. Summary We can have a more productive debate about the value of EBM by being clearer about the nature of EBM and its relationship to alternative approaches to medicine.

  7. Beyond the realism debate: The metaphysics of 'racial' distinctions.

    Science.gov (United States)

    Lemeire, Olivier

    2016-10-01

    The current metaphysical race debate is very much focused on the realism question whether races exist. In this paper I argue against the importance of this question. Philosophers, biologists and anthropologists expect that answering this question will tell them something substantive about the metaphysics of racial classifications, and will help them to decide whether it is justified to use racial categories in scientific research and public policy. I argue that there are two reasons why these expectations are not fulfilled. First of all, the realism question about race leads to a very broad philosophical debate about the semantics of general terms and the criteria for real kinds, rather than to a debate about the metaphysics of racial categories specifically. Secondly, there is a type of race realism that is so toothless that it is almost completely uninformative about the metaphysics of race. In response to these worries, I argue that the metaphysical race debate should rather be focused on the question in what way and to what extent 'racial' distinctions can ground the epistemic practices of various scientific disciplines. I spell out what I mean by this, and go on to demonstrate that trying to answer this question leads to a more fruitful metaphysical debate.

  8. Should we prescribe heroin? A current Scottish debate.

    Science.gov (United States)

    Gallagher, J; McKeganey, N

    2007-11-01

    There have been recent calls from within both Scotland and England for the wider prescription of heroin to heroin addicts as a way of coping with our burgeoning drug problem and as a route to reducing drug related criminality. But how feasible is heroin prescribing in this context? This paper considers some of the existing research evidence relating to heroin prescribing and looks also at the ethics and practicalities of prescribing heroin to heroin addicts in Scotland. We conclude that whilst the evidence on the benefits of heroin prescribing is far from clear cut there is a case for mounting a Scottish trial of heroin prescribing. Such a trial would need to be tightly controlled and rigorously evaluated. It would need to show that heroin prescribing was associated not only with a comparable level of harm reduction, as methadone prescribing, but that it was also an effective route towards drug users' eventual recovery and drug cessation.

    Full Text Available This article aims to provide an overview of the online interaction of the ‘Debating Europe’ platform using the theoretical framework of dialogic communication. A brief historical approach of the notion “Web 2.0” further informs about the functions of the ‘Debating Europe’ platform and its mission statement. Related work opens an interrogation on the ‘Debating Europe’ platform as a virtual space meant to connect European citizens and politicians in online debates concerning EU matters. The empirical study regards the use of dialogic principles on the ‘Debating Europe’ platform, focusing on a cross comparison of its three Internet channels: the website, the Facebook page and the Twitter account. The results indicate the website as the main dialogic channel, while Facebook and Twitter fulfill mainly information dissemination purposes.

  14. ON THE ROLE OF ECONOMIC HISTORY IN THE CONVERGENCE DEBATE

    Directory of Open Access Journals (Sweden)

    Michael W. Brandl

    2000-01-01

    Full Text Available For over a decade and a half macroeconomists who study economic growth have been embroiled in a debate over the issue of economic convergence. That is, for similar economies do poorer economies tend to catch-up to richer economies? The answer to the question goes to the very core of how economists explain economic growth. Macro theorists have developed scores of economic growth models to address this question. In addition, numerous econometric tests have been conducted attempting to answer this convergence question. Yet one group of economists that have not had much impact on this issue are economic historians. However when economic history is used to augment the theoretical and empirical investigations of the convergence question, the results can be striking. This paper seeks to stimulate economic historians interest in the convergence debate by illustrating the impact economic historical research can have on this important topic.

    2006-01-01

    Debating about the climate warming is reviewed. Discussions have focused on the validity of the temperature reconstruction for the last millennium made by Mann et al. Arguments against and for the reconstruction are introduced. Temperature reconstructions by other authors are examined, including the one carried out by Wang et al. in 1996. It is concluded that: (1) Ability of reproducing temperature variability of time scale less than 10 a is limited, so no sufficient evidence proves that the 1990s was the warmest decade, and 1998 was the warmest year over the last millennium. (2) All ofthe temperature reconstructions by different authors demonstrate the occurrence of the MWP (Medieval Warm Period) and LIA (Little Ice Age) in low frequency band of temperature variations, though the peak in the MWP and trough in LIA varies from one reconstruction to the others. Therefore, terms of MWP and LIA can be used in studies of climate change. (3) The warming from 1975 to 2000 was significant, but we do not know if it was the strongest for the last millennium, which needs to be proved by more evidence.

  18. Investigations on contribution of glial inwardly-rectifying K+ current to membrane potential and ion flux: An experimental and theoretical study

    Directory of Open Access Journals (Sweden)

    Sheng-Nan Wu

    2015-01-01

    Full Text Available The inwardly rectifying K+ current [IK(IR] allows large inward K+ currents at potentials negative to K+ equilibrium potential (EK and it becomes small outward K+ currents at those positive to EK. How changes of such currents enriched in glial cells can influence the functions of glial cell, neurons, or both is not clearly defined, although mutations of Kir4.1 channels have been demonstrated to cause serious neurological disorders. In this study, we identified the presence of IK(IR in human glioma cells (U373 and U87 cells. The amplitude of IK(IR in U373 cells was subject to inhibition by amitriptyline, arecoline, or BaCl2. The activity of inwardly rectifying K+ channels was also clearly detected, and single-channel conductance of these channels was calculated to be around 23 pS. Moreover, based on a simulation model derived from neuron–glial interaction mediated by ion flux, we further found out that incorporation of glial IK(IR conductance into the model can significantly contribute to regulation of extracellular K+ concentrations and glial resting potential, particularly during high-frequency stimulation. Glial cells and neurons can mutually modulate their expression of ion channels through K+ ions released into the extracellular space. It is thus anticipated that glial IK(IR may be a potential target utilized to influence the activity of neuronal and glial cells as well as their interaction.

    2015-05-01

    Full Text Available El aborto voluntariamente inducido se mantiene a lo largo de la historia como práctica prevalente sumida en la oscuridad y en la clandestinidad porque toda fecundación extramatrimonial ha sido socialmente rechazada. Desde mediados del siglo 20, se produce una actitud de tolerancia que lleva a la despenalización y legalización del aborto, según dos modelos jurídicos: el modelo de indicaciones, conocido como aborto terapéutico, adoptado en naciones conservadoras, y el modelo de plazos que permite a la mujer requerir el aborto dentro del primer trimestre de embarazo. La liberalización del aborto obedece a la invariable política social que busca eliminar la clandestinidad y sus nocivos efectos, para educar, disuadir y, eventualmente, considerar el aborto como un servicio médico seguro y accesible dentro de los marcos legalmente establecidos, todas normativas orientadas a disminuir la incidencia del aborto procurado. El Proyecto de Ley de despenalización del aborto presentado al Parlamento chileno obedece al modelo de indicaciones, que son presentadas en forma muy restrictiva y por ende no cumplen con los tres objetivos que deben orientarla: 1 Enmarcar legalmente la práctica del aborto; 2 Contribuir a la paz social; 3 Resolver el problema de salud pública del aborto clandestino. Es de urgencia abrir el debate a incluir alternativas más resolutivas, en consonancia con la tendencia general a preferir el modelo de plazos que incluye el respeto a la decisión de la mujer.

    Science.gov (United States)

    1999-04-01

    This is not the first time the intriguing carbonaceous compound has been detected in space. A peculiar elite of twelve stars are known to produce it. The star now added by ISO to this elite is one of the best representatives of this exclusive family, since it emits a very strong signal of the compound. Additionally ISO found a second new member of the group with weaker emission, and also observed with a spectral resolution never achieved before other already known stars in this class. Astronomers think these ISO results will help solve the mystery of the true nature of the compound. Their publication by two different groups, from Spain and Canada, has triggered a debate on the topic, both in astronomy institutes and in chemistry laboratories. At present, mixed teams of astrophysicists and chemists are investigating in the lab compounds whose chemical signature or "fingerprint" matches that detected by ISO. Neither diamonds nor fullerenes have ever been detected in space, but their presence has been predicted. Tiny diamonds of pre-solar origin --older than the Solar System-- have been found in meteorites, which supports the as yet unconfirmed theory of their presence in interstellar space. The fullerene molecule, made of 60 carbon atoms linked to form a sphere (hence the name "buckyball"), has also been extensively searched for in space but never found. If the carbonaceous compound detected by ISO is a fullerene or a diamond, there will be new data on the production of these industrially interesting materials. Fullerenes are being investigated as "capsules" to deliver new pharmaceuticals to the body. Diamonds are commonly used in the electronics industry and for the development of new materials; if they are formed in the dust surrounding some stars, at relatively low temperatures and conditions of low pressure, companies could learn more about the ideal physical conditions to produce them.

    2015-01-01

    Twilight Sleep (TS) describes the delivery, via an injection, of an amnestic drug cocktail to a parturient woman throughout labor. In order to understand the development of modern-day rhetoric surrounding childbirth methods and procedures, this article explores the debate over TS between the public and technical sphere in New York City between 1914 and 1916 and examines the ways in which this debate altered obstetric health care for middle- and upper-class White women. The public response to this campaign posed a direct challenge to male obstetricians in New York City, many of whom were ill-equipped, both literally and figuratively, to use this procedure. Using a feminist rhetorical criticism, we examined the pro-TS rhetoric of women writers in New York City, the methods they borrowed from the women's movement, and the ensuing dialogue between the public and technical spheres. For this study, we analyzed journal and newspaper articles, a pamphlet, a collection of pro-TS organizational documents, letters to the editor, and books published about TS and the history of birth. Lastly, we analyzed theoretical notions of childbirth in women's health and communication studies. After examining the TS debate, we found that birth practices for middle- and upper-class women in New York City shifted and the obstetric community gained ascendancy over female midwifery. We also found that in certain instances, the rhetoric of pro-TS activists was more technically accurate than the rhetoric of some physicians. Hence the TS debate emerged from an argument over the right to use technical language in the technical and/or the public sphere. Conclusions and implications offered by this historical, feminist analysis question our current understanding of women's health and birthing practices, doctor-patient communication, and patient empowerment and access to technical knowledge.

Because it, it this is important to have tools to collect valid and reliable information about moral in social situations defined as social and personal behavior issue. This paper presents a technical note of The Morally Debatable Behaviors Scale (MDBS from Harding & Phillips (1986, which was developed in USA and mainly focused on young people and adults. This technical note makes direct reference to a recent Latin American study (Merino & Grimaldo, 2010; this article focuses on the internal structure and the problems associated with evidences of factorial complexity among items of the MDBS. This means that the interpretation of scores is not factorially simple and could not be achieved by a conceptual distinction between the latent constructs applied to the study sample.. The results in the previous study of the factorial complexity leads the researcher to decide whether an instrument for measuring this aspect may contain a reasonable amount of complexity that is consistent with what is in reality, or look for the unidimensional and simple structure.

  17. Putting flexible animal prospection into context: escaping the theoretical box.

    Science.gov (United States)

    Osvath, Mathias

    2016-01-01

    The debate on non-human future-oriented cognition has long revolved around the question whether such cognition at all occurs. Closer inspection reveals just how much cognition in general-down to its simplest forms-is geared toward predicting the future in a bid to maintain homeostasis and fend off entropy. Over the course of life's existence on Earth, evolution and natural selection have, through a series of evolutionary arms races, gotten increasingly good at achieving this. Prospection has reached its current pinnacle based partly on a system for episodic cognition that-as research increasingly is showing-is not limited principally to human beings. Nevertheless, and despite some notable recent defections, many researchers remain convinced of the merits of the Bischof-Köhler Hypothesis with its claim that no species other than human beings is able to anticipate future needs or otherwise live in anything other than the immediate present moment. What might, at first, appear to be empirical disputes turn out to reveal largely unquestioned theoretical divides. Without due care, one risks setting out conditions for 'true' future orientation that are irrelevant for describing human cognition. In sorting out the theoretical and terminological muddle framing contemporary debate, this article makes a plea for moving beyond past dogmas while putting animal prospection research into the context of evolution and contemporary cognitive science.

    The stray field of eddy current septum magnets is analyzed theoretically and also simulated by a computer program. The results from theoretical analysis agree well with those simulated from OPERA program. The maximum of stray field varies inversely with the thickness of septum. It delays some time with respect to the maximum of main field, and the delay time is proportional to square of the thickness of the septum. After stray field increases to its maximum, it starts to decrease very slowly to zero. To reduce stray field fast, one can adopt full sine wave pulse current to power the magnet, The stray field can be reduced to 0.2% at any position and any time by using composite septum (2.4mm Cu+0.6mm Fe). The homogeneity of the main field is superior to 1%.%从理论上推导了涡流型切割磁铁的漏场变化规律. 以上海同步辐射装置(SSRF)用涡流型切割磁铁为例,进行了分析性计算和讨论,并与OPERA程序模拟计算的结果进行了比较. 在此基础上,提出了降低漏场的方法和措施.

    2010-09-01

    The framing of issues in the mass media plays a crucial role in the public understanding of science and technology. This article contributes to research concerned with the analysis of media frames over time by making an analytical distinction between implicit and explicit media frames, and by introducing an automated method for the analysis of implicit frames. In particular, we apply a semantic maps method to a case study on the newspaper debate about artificial sweeteners, published in the New York Times between 1980 and 2006. Our results show that the analysis of semantic changes enables us to filter out the dynamics of implicit frames, and to detect emerging metaphors in public debates. Theoretically, we discuss the relation between implicit frames in public debates and the codification of meaning and information in scientific discourses, and suggest further avenues for research interested in the automated analysis of frame changes and trends in public debates.

This article contributes to research concerned with diachronic analysis of media frames by making an analytical distinction between implicit and explicit media frames, and by introducing an automated method for analysing diachronic changes of implicit frames. In particular, we apply a semantic maps method to a case study on the newspaper debate about artificial sweeteners, published in The New York Times (NYT) between 1980 and 2006. Our results show that the analysis of semantic changes enables us to filter out the dynamics of implicit frames, and to detect emerging metaphors in public debates.

  4. Theoretical geology

    Mikeš, Daniel

    2010-05-01

    Theoretical geology Present day geology is mostly empirical of nature. I claim that geology is by nature complex and that the empirical approach is bound to fail. Let's consider the input to be the set of ambient conditions and the output to be the sedimentary rock record. I claim that the output can only be deduced from the input if the relation from input to output be known. The fundamental question is therefore the following: Can one predict the output from the input or can one predict the behaviour of a sedimentary system? If one can, than the empirical/deductive method has changes, if one can't than that method is bound to fail. The fundamental problem to solve is therefore the following: How to predict the behaviour of a sedimentary system? It is interesting to observe that this question is never asked and many a study is conducted by the empirical/deductive method; it seems that the empirical method has been accepted as being appropriate without question. It is, however, easy to argument that a sedimentary system is by nature complex and that several input parameters vary at the same time and that they can create similar output in the rock record. It follows trivially from these first principles that in such a case the deductive solution cannot be unique. At the same time several geological methods depart precisely from the assumption, that one particular variable is the dictator/driver and that the others are constant, even though the data do not support such an assumption. The method of "sequence stratigraphy" is a typical example of such a dogma. It can be easily argued that all the interpretation resulting from a method that is built on uncertain or wrong assumptions is erroneous. Still, this method has survived for many years, nonwithstanding all the critics it has received. This is just one example of the present day geological world and is not unique. Even the alternative methods criticising sequence stratigraphy actually depart from the same

  6. An Overview of Latin American Health Policies and Debates

    2010-04-01

    Full Text Available It is now 15 years since the publication of Investing in Health (World Bank, 1993, a report which set the course for health care system reform in Latin America and around of the world. Since that time a great many studies about the reforms have been published and new reforms have been launched to “correct” the defects of the earlier ones. The objective of this paper is to call into question the entire current political debate over health care, as well as to clarify key concepts and practices. To this end I will analyze the current vogue of interrelated proposals for a second reform of the state. I will examine debates over insurance as a way of grant universal coverage; the separation between the regulation, financing and provision of health services; and the public private partnerships for the construction, financing, and management of hospitals. This paper will also examine the development of a new scientific discourse around “evidence-based policies” and academic referral networks. The goal of this paper is not to offer a comprehensive treatment of these issues, but rather to question some assumptions and contribute to the larger debate.

    Full Text Available Following publication of NASCIS II, methylprednisolone sodium succinate (MPSS was hailed as a breakthrough for patients with acute spinal cord injury (SCI. MPSS use for SCI has since become very controversial and it is our opinion that additional evidence is unlikely to break the stalemate amongst clinicians. Patient opinion has the potential to break this stalemate and we review our recent findings which reported that spinal cord injured patients informed of the risks and benefits of MPSS reported a preference for MPSS administration. We discuss the implications of the current MPSS debate on translational research and seek to address some misconceptions which have evolved. As science has failed to resolve the MPSS debate we argue that the debate is an increasingly philosophical one. We question whether SCI might be viewed as a serious condition like cancer where serious side effects of therapeutics are tolerated even when benefits may be small. We also draw attention to the similarity between the side effects of MPSS and isotretinoin which is prescribed for the cosmetic disorder acne vulgaris. Ultimately we question how patient autonomy should be weighed in the context of current SCI guidelines and MPSS′s status as a historical standard of care.

  11. The Role of Trait Emotional Intelligence in Academic Performance: Theoretical Overview and Empirical Update.

    Science.gov (United States)

    Perera, Harsha N

    2016-01-01

    Considerable debate still exists among scholars over the role of trait emotional intelligence (TEI) in academic performance. The dominant theoretical position is that TEI should be orthogonal or only weakly related to achievement; yet, there are strong theoretical reasons to believe that TEI plays a key role in performance. The purpose of the current article is to provide (a) an overview of the possible theoretical mechanisms linking TEI with achievement and (b) an update on empirical research examining this relationship. To elucidate these theoretical mechanisms, the overview draws on multiple theories of emotion and regulation, including TEI theory, social-functional accounts of emotion, and expectancy-value and psychobiological model of emotion and regulation. Although these theoretical accounts variously emphasize different variables as focal constructs, when taken together, they provide a comprehensive picture of the possible mechanisms linking TEI with achievement. In this regard, the article redresses the problem of vaguely specified theoretical links currently hampering progress in the field. The article closes with a consideration of directions for future research.

    Full Text Available This paper examines current debates on the fate of Moroccan Jews under the Vichy regime and the attitude of the sultan towards his Jewish subjects. Due to wide-ranging contributions by the media and via the internet, these debates are not confined to political or intellectual circles but also involve ‘non-professionals’. My aim is to examine to what extent discussions about the Second World War are relevant in contemporary Morocco, to shed light on how established narratives are challenged by new questions, and to understand the meanings such debates have for the way Moroccans see and position themselves in contemporary Moroccan society.

    Full Text Available Theoretical sorting has brought the analyst to the point of pent-up pressure to write: to see the months of work actualized in a “piece.” But this is only a personal pressure. The goal of grounded theory methodology, above all is to offer the results to the public, usually through one or more publications. We will focus on writing for publication, which is the most frequent way that the analyst can tell how people are “buying” what really matters in sociology, or in other fields.Both feedback on and use of publications will be the best evaluation of the analyst’s grounded theory. It will be his main source or criticism, constructive critique, and frequently of career rewards. In any case, he has to write to expand his audience beyond the limited number of close colleagues and students. Unless there is a publication, his work will be relegated to limited discussion, classroom presentation, or even private fantasy. The rigor and value of grounded theory work deserves publication. And many analysts have a stake in effecting wider publics, which makes their substantive grounded theory count.

It contains the results of research on new methods of the parameter estimation, a study on robustness properties of the M-estimation, control network and deformation analysis, and geodetic time series analysis. The main achievements in the geodetic parameter estimation involve a new model of the M-estimation with probabilistic models of geodetic observations, a new Shift-Msplit estimation, which allows to estimate a vector of parameter differences and the Shift-Msplit(+ that is a generalisation of Shift-Msplit estimation if the design matrix A of a functional model has not a full column rank. The new algorithms of the coordinates conversion between the Cartesian and geodetic coordinates, both on the rotational and triaxial ellipsoid can be mentioned as a highlights of the research of the last four years. New parameter estimation models developed have been adopted and successfully applied to the control network and deformation analysis.

Statistical properties of these time series are also presented using different statistical tests as well as 2nd, 3rd and 4th moments about the mean. The new forecasts methods are presented which enable prediction of the considered time series in different frequency bands.

  18. [Personal genomics: are we debating the right Issues?].

    Vayena, E; Mauch, F

    2012-07-25

    The debate about personal genomics and their role in personalized medicine has been, to some extent, hijacked by the controversy about commercially available genomic tests sold directly to consumers. The clinical validity and utility of such tests are currently limited and most medical associations recommend that consumers refrain from testing. Conversely, DTC genomics proponents and particularly the DTC industry argue that there is personal utility in acquiring genomic information. While it is necessary to debate risks and benefits of DTC genomics, we should not lose sight of the increasingly important role that genomics will play in medical practice and public health. Therefore, and in anticipation of this shift we also need to focus on important implications from the use of genomics information such as genetic discrimination, privacy protection and equitable access to health care. Undoubtedly, personal genomics will challenge our social norms maybe more than our medicine. Sticking to the polarization of «to have or not to have DTC genomics» risks to takes us away from the critical issues we need to be debating.

    There has been increased interest in cannabis as a medicine both nationally and internationally. Internationally, cannabis is accepted as a medication for a variety of purposes in a variety of legal guises and this, associated with anecdotes of the utility of cannabis as medication has led for calls for it to be 'medicalised' in New Zealand. This viewpoint discusses the issues associated with this approach to accessing cannabis and some of the difficulties that may be associated with it. It is important doctors are at the forefront of the debate surrounding medicalised cannabis. Recommendations as to the ongoing debate are offered.

    This article describes the different theories of various authors that have tried to explain, from the psychoanalytic theory, the early childhood autistic disorder described by Leo Kanner in 1943. Autism differs from other childhood disorders and is characterized by a significant disconnection. This article sustains that there are two different lines of thought. One that explains the disorder as a regression during a normal phase of development; and the other as an early defense in response to extreme situations. These two theories are present in all the current considerations about autism as a theoretical debate that goes beyond the clinical observation and determines the direction of the cure.

  6. The Multi-faceted Debate on Decentralization and Collective Welfare

    Directory of Open Access Journals (Sweden)

    Sandra Gomes

    2010-12-01

    Full Text Available Studies on the relation between decentralization reforms and the performance of governments and their policies have presented a myriad of theoretical developments but inconclusive results on the empirically verifiable effects of these propositions. Many of the reviews carried out thus far in this field merely criticize these propositions without proposing alternatives for analysis. This article presents a review of this debate in a very specific way: it selects the propositions that points towards the causal factors explaining government’s responsiveness to its citizens. Four types of interpretations are discussed: 1 allocative efficiency theories of fiscal decentralization, 2 the multiple dimensions of decentralization, 3 the institutional design of reforms, and 4 the qualitative aspects of governance. Despite the observed divergences in the use of concepts, analytical preoccupations and in relation to the empirical operationalization of variables, this article points to a series of hypotheses that could be extracted from this debate and that could be the object of an empirical test.

  7. Political debate on weblogs: a virtual public sphere for deliberation?

    Directory of Open Access Journals (Sweden)

    Gil Baptista Ferreira

    2011-12-01

    Full Text Available Taking as reference the deliberative democracy model, my aim is to assess the democratic potential of online discursive spaces to 1 characterize the communication observed within them and 2 critically evaluate that potential and ask whether or not blogging is consistent with the main theoretical norms of deliberative democracy. The main question asked is whether these electronic debates stimulate deliberation within the public sphere, through non-coercive communication, freedom of expression, an unrestricted agenda. I argue that while it has the potential to be a valuable practice that can expand the opportunities for citizens to engage politically, so far this initial promise remains unfulfilled. Considering the different types of uses that individuals make of these spaces, it seems that the political communication exchange on weblogs do not meet the ideal requirements of the public sphere, and blogging fails to satisfy several important criterion of deliberative democracy. I conclude suggesting explanations for online political apathy and lack of deliberative debate.

    Full Text Available O artigo reúne e discute as abordagens feministas para as Relações Internacionais. O encontro entre os campos dos Estudos de Gênero e Relações Internacionais data de pouco mais de duas décadas, e representa um movimento simultâneo ao do surgimento do chamado "terceiro debate" em RI. Dessa forma, pretende-se, além de discutir a aplicação do gênero como categoria de análise para as relações internacionais, argumentar que essa aplicação está intimamente ligada às críticas às teorias convencionais de RI que surgem no contexto do terceiro debate.The article collects and discusses feminist approaches to International Relations. The encounter between the fields of Gender Studies and International Relations dates back to a little over two decades, and represents a movement that was almost simultaneous to the beginning of what is called in the IR field the "third debate". In this sense, besides discussing the use of gender as a category of analysis for international relations, the article intends to argue that this use of gender in IR is closely connected to the critics to conventional IR theories that emerge in the context of the third debate.

    Science.gov (United States)

    Schmidt, Markus; Meyer, Angela; Cserer, Amelie

    2015-07-01

    Synthetic biology (SB) is a new techno-scientific field surrounded by an aura of hope, hype and fear. Currently it is difficult to predict which way the public debate - and thus the social shaping of technology - is heading. With limited hard evidence at hand, we resort to a strategy that takes into account speculative design and diegetic prototyping, accessing the Bio:Fiction science film festival, and its 52 short films from international independent filmmakers. Our first hypothesis was that these films could be used as an indicator of a public debate to come. The second hypothesis was that SB would most likely not follow the debate around genetic engineering (framing technology as conflict) as assumed by many observers. Instead, we found good evidence for two alternative comparators, namely nanotechnology (technology as progress) and information technology (technology as gadget) as stronger attractors for an upcoming public debate on SB.

    The mammographic screening debate has been running for decades. The temperature of this debate is unusually high, and all participants, regardless of viewpoint, seem to have a conflict of interest. Another unusual aspect of this debate is the focus on study design, and in particular on designs that some think exceeded their usefulness decades ago. What are the questions that remain to be answered in this debate? Are there methodological issues that have not been adequately addressed? Do we have the right tools to provide up-to-date answers to how women can best protect themselves against dying from breast cancer? This commentary discusses some of the current issues.See related Opinion articles http://www.biomedcentral.com/1741-7015/10/106 and http://www.biomedcentral.com/1741-7015/10/163.

  19. Possessing History and American Innocence: James Baldwin, William F. Buckley, Jr., and the 1965 Cambridge Debate

    Directory of Open Access Journals (Sweden)

    Daniel Robert McClure

    2016-12-01

    Full Text Available The 1965 debate at Cambridge University between James Baldwin and William F. Buckley, Jr., posed the question: “Has the American Dream been achieved at the Expense of the American Negro?” Within the contours of the debate, Baldwin and Buckley wrestled with the ghosts of settler colonialism and slavery in a nation founded on freedom and equality. Framing the debate within the longue durée, this essay examines the deep cultural currents related to the American racial paradox at the height of the Civil Rights movement. Underscoring the changing language of white resistance against black civil rights, the essay argues that the Baldwin and Buckley debate anticipated the ways the U.S. would address racial inequality in the aftermath of the civil rights era and the dawn of neoliberalism in the 1970s.

    2017-02-26

    Despite numerous studies identifying a broad range of harms associated with the use of spanking and other types of physical punishment, debate continues about its use as a form of discipline. In this commentary, we recommend four strategies to move the field forward and beyond the spanking debate including: 1) use of methodological approaches that allow for stronger causal inference; 2) consideration of human rights issues; 3) a focus on understanding the causes of spanking and reasons for its decline in certain countries; and 4) more emphasis on evidence-based approaches to changing social norms to reject spanking as a form of discipline. Physical punishment needs to be recognized as an important public health problem.

    "Fatal Exit: The Automotive Black Box Debate cuts through thirty years of political wrangling and institutional biases to provide an argument for the Motor Vehicle Event Data Recorder (MVEDR). This automotive equivalent of an airplane's flight recorder or black box is intended to solve the mysteries of car crashes and improve the safety of our roads. The reader is taken inside the automotive industry and the government highway safety establishment to foster an understanding of the politics and the positions on all sides of this safety debate. The author takes an unbiased approach, chronologically presenting each argument and uncovering the agendas and mandates of each of the stakeholders." "This publication is essential reading for all consumers who need to have their voices heard on this critical issue, as well as for attorneys, public safety advocates, public policy administrators, engineers, automotive professionals, journalists, and insurance executives."--Jacket.

  4. Quantitative and qualitative research: beyond the debate.

    Gelo, Omar; Braakmann, Diana; Benetka, Gerhard

    2008-09-01

    Psychology has been a highly quantitative field since its conception as a science. However, a qualitative approach to psychological research has gained increasing importance in the last decades, and an enduring debate between quantitative and qualitative approaches has arisen. The recently developed Mixed Methods Research (MMR) addresses this debate by aiming to integrate quantitative and qualitative approaches. This article outlines and discusses quantitative, qualitative and mixed methods research approaches with specific reference to their (1) philosophical foundations (i.e. basic sets of beliefs that ground inquiry), (2) methodological assumptions (i.e. principles and formal conditions which guide scientific investigation), and (3) research methods (i.e. concrete procedures for data collection, analysis and interpretation). We conclude that MMR may reasonably overcome the limitation of purely quantitative and purely qualitative approaches at each of these levels, providing a fruitful context for a more comprehensive psychological research.

    Full Text Available The present work is a research on Gilles Deleuze’s contribution to the contemporary biopolitical debate. To begin with, we analyze his interpretation of Foucault’s conception of biopolitics, especially the vitalist matrix of his reading, and we examine its impact on the distinction between “biopower” and “biopolitics” according to certain authors (Lazzarato, Negri, Revel. We then reveal the presence of deleuzian notions in other perspectives (the “impersonal” in Esposito, the “society of control” in Negri. Finally, we propose renewing the fundamental tensions of the debate on Life, Politics, Language and the Condition of Man, based on concepts elaborated by Deleuze

    The European patent system allows for the introduction of moral issues into decisions about the granting of patents. This feature has greatly impacted European debates about the patenting of biotechnology. This essay explores the European experience, in both the European Union and the European Patent Organization. It argues that there has been great confusion surrounding these issues primarily because the Europeans have not developed a general theory about when exclusion from patentability is the best social mechanism for dealing with morally offensive technologies.

    Arte, Ciudad y Territorio constituyen múltiples conexiones que se superponen entre sí, formando un conjunto indisoluble a la hora de pensar en la URBS y la CIVITAS. Las diferentes disciplinas utilizan uno o varios de estos caminos para abordar la cuestión del espacio urbano y elaborar propuestas que buscan incentivar el pensamiento crítico del ciudadano al mismo tiempo que potencian la cohesión social.

    Para tratar este tema, se organiza el tercer debate Professional URBS que produce una conexión de dos horas a través de videoconferencia entre las ciudades de Barcelona, Ciudad de México, Nancy, Estella y Granada. Se crea así una mesa de debate a la que fueron invitados cuatro expertos con diferentes trayectorias y experiencias en urbanismo, socioconstruccionismo, acciones sociales y teatro urbano. El producto de este debate es el testimonio de un intercambio de conocimiento entre personas y disciplinas muy diferentes entre sí pero con un objetivo común: hallar las claves del espacio público para hacerlo más humano y democrático.

  11. Abortion: at the still point of the turning conscientious objection debate.

    Science.gov (United States)

    Bedford, Elliott Louis

    2012-06-01

    Abortion is the central issue in the conscientious objection debate. In this article I demonstrate why this is so for two philosophical viewpoints prominent in American culture. One, represented by Patrick Lee and Robert P. George, holds that the fundamental moral value of being human can be found in bare life and the other, represented by Tom Beauchamp and James Childress, holds that this fundamental value is found in the life that can choose and determine itself. First, I articulate Lee and George's philosophical theory and demonstrate how the fundamental moral value of their theory, personhood, is represented in the issue of abortion. Second, I examine Beauchamp and Childress' theoretical vision and demonstrate how their fundamental moral value, the right to autonomous self-determination, is represented in abortion. Third, I sketch the theoretical and practical dynamics of the conscientious objection debate as well as each author's understanding of conscience. Fourth, I demonstrate how abortion, which represents their respective fundamental value, shapes each perspectives' approach to the conscientious objection debate. I conclude that because each theory finds its fundamental value represented in the issue of abortion, each perspective is bound to engage the conscientious objection debate in a way that centers on the issue of abortion.

The “social turn” in information science is not just exemplified in relation to the works of Marcia Bates but in relation to many different...... researchers in the field. Therefore it should not be taken personally, and the debate should focus on the substance. Marcia Bates has contributed considerably to information science.

  16. Catholic options in the abortion debate.

    Science.gov (United States)

    Maguire, D C

    1990-01-01

    The little-known Roman Catholic theological doctrine of probabilism, an ethical system explicated in all manuals of moral theology, is explained using as an example the dilemma of abortion. Probabilism is based on the notion that a doubtful moral obligation may not be imposed as though it were certain. "Ubi dubium, ibi libertas," means where there is doubt, there is freedom. There are 2 types of moral probability, intrinsic probability, where the individual, without the help of moral theologians, perceives the inapplicability of a particular moral teaching; and extrinsic probability, which involves reliance on the findings of 5 or 6 reputable moral theologians, who may hold a liberal view. Probabilism implies a reasonable doubt, and one's reasons must be cogent, but not necessarily conclusive. Today's abortion debate is an example of a respectable debate, where the liberal view has been endorsed by a number of reputable religious or other humanitarian bodies that in some cases abortion is not always immoral. Other examples in history are the view once taught by the church that taking interest on loans was immoral, that depriving slaves and women of civil rights on non-Catholics of religious or political freedom was moral. For today's legislators, there is a precedent throughout theological history for the state permitting an evil: both St. Augustine and St. Thomas Aquinas wrote that prostitution, although evil, should not be outlawed, because worse evils would occur with prohibition. Legislators who personally find abortion always immoral can support a Roe V. Wade decision because 1) it does not require anyone to have an abortion, and 2) the abortion debate, among Catholics, and non-Catholics is not settled.

    Full Text Available The following article establishes a critique to the prevalent conception of political communication by focusing on the concept of collective democracy, which is drawn from English political theory. This approach, proposed by David Mena PhD., a researcher from Universidad de las Americas, Puebla, in Mexico, is applied here to contrast the concept of political marketing with the notion of communication as a model for political participation through collective decision-making. Finally, in the conclusive section, the author emphasizes two ideas pointed out by Mena: first, the design of political campaigns as education promotion, and second, the notion of the political debate as a public good.

    . The debate on the development of advanced nursing competences. The dossier aims to describe and disentagle the present Italian and international debate on the development and recognition of advanced nursing competences. Following a general brief description of the legislative national background, the attention is first of all focused on the lack of clarity on the definition of advanced competence, which is further complicated by the issue of their formal, contractual and economic recognition. To explore these issues a list of contributions is presented and some proposals are formulated to favor a better oriented development of the debate: a. A convenience sample of 139 nurses were interviewed asking to describe problems occurred in the last month that could prompt the intervention of an expert nurse and to list the clinical, managerial and educational competences of a specialized nurse in their ward. The results document the quality and the dispersion of the definitions which are perceived and applied in the general settings of care. b. The issue the post basic courses (master, specialization) offered to nurses in 2015-2016 by Italian universities were described and their aims. While the contribution of the courses in increasing the theoretical knowledge is well defined, the aims and the description of the clinical training are badly developed and an acquisition of advanced competences would seem unlikely. c. The definition of advanced competences was explored in the international literature: while evidences are available on the impact of advanced nursing on patients' outcomes, what is advanced nursing is far from being clear, and an impressive list of roles, activities and functions are considered advanced. d. Although at national level there is no formal recognition for nurses with advanced competences (with the exception of the head nurse that holds mostly an organizational rather than clinical role), the opportunities for promoting the role of specialistic

  3. The LNT Debate in Radiation Protection: Science vs. Policy.

    Mossman, Kenneth L

    2012-01-01

    There is considerable interest in revisiting LNT theory as the basis for the system of radiation protection in the US and worldwide. Arguing the scientific merits of policy options is not likely to be fruitful because the science is not robust enough to support one theory to the exclusion of others. Current science cannot determine the existence of a dose threshold, a key piece to resolving the matter scientifically. The nature of the scientific evidence is such that risk assessment at small effective doses (defined as scientifically defensible. This paper argues for an alternative approach by looking at the LNT debate as a policy question and analyzes the problem from a social and economic perspective. In other words, risk assessment and a strictly scientific perspective are insufficiently broad enough to resolve the issue completely. A wider perspective encompassing social and economic impacts in a risk management context is necessary, but moving the debate to the policy and risk management arena necessarily marginalizes the role of scientists.

  10. The ethics of limiting informed debate: censorship of select medical publications in the interest of organ transplantation.

    Science.gov (United States)

    Potts, Michael; Verheijde, Joseph L; Rady, Mohamed Y; Evans, David W

    2013-12-01

    Recently, several articles in the scholarly literature on medical ethics proclaim the need for "responsible scholarship" in the debate over the proper criteria for death, in which "responsible scholarship" is defined in terms of support for current neurological criteria for death. In a recent article, James M. DuBois is concerned that academic critiques of current death criteria create unnecessary doubt about the moral acceptability of organ donation, which may affect the public's willingness to donate. Thus he calls for a closing of the debate on current death criteria and for journal editors to publish only critiques that "substantially engage and advance the debate." We argue that such positions as DuBois' are a threat to responsible scholarship in medical ethics, especially scholarship that opposes popular stances, because it erodes academic freedom and the necessity of debate on an issue that is literally a matter of life and death, no matter what side a person defends.

  11. Ações afirmativas e o debate sobre racismo no Brasil Afirmative actions and the debate on racism in Brazil

    2006-01-01

    Full Text Available O tema "ações afirmativas" tem dividido a opinião pública e esquentado o debate acadêmico. Enquanto alguns especialistas e militantes negros entendem a introdução de ações afirmativas como uma forma de combate ao racismo, uma vez que, segundo esta interpretação, a discriminação positiva ajudará os historicamente desprivilegiados a criar e fortalecer uma identidade positiva, outros vêem em tais medidas um ataque perigoso contra a "maneira tradicional brasileira" de se relacionar com as "diferenças humanas" e temem que políticas como essas possam instigar conflitos raciais abertos. Embora os defensores e opositores à introdução de projetos de ação afirmativa raramente explicitem o que entendem por racismo e como interpretam este fenômeno social, é possível detectar nesses discursos distintas linhas de argumentação que remetem a orientações teóricas diferentes no que diz respeito à análise de categorias como "raça" e "cor".The "affirmative action" issue has split the public opinion and heated up the academic debate. While some experts and black activists see the affirmatives actions as a way to fight racism, since the positive discrimination could help the historically underprivileged to create and empower a positive identity, others see such measures as a dangerous attack against the "traditional brazilian way" of dealing with "human differences". The latter fear that such policies may unleash racial conflicts. Although both sides barely explain what they mean for racism and how they understand that social phenomenon, it is possible to discern in those discourses different lines of argument, which can be related to different theoretical orientations about the analysis of such concepts as "race" and "color".

  12. Autobiography, autofiction: theoretical debate from El escritor y el otro by Carlos Liscano

    Directory of Open Access Journals (Sweden)

    Selomar Claudio Borges

    2012-11-01

    Full Text Available The book El escritor y el otro by the author Carlos Liscano from Uruguay, proposes a deep discussion on the games of fictional creation, and also reflects the possible limits of the authors factual life and its written form. With that starting point, this paper aims to argue how Liscano’s text suggests the problematization between the fiction that appears to be a life story and the mutual contaminations derived from that crossing. In El escritor y el otro both life and writing are fictionalized, acting as a literature that looks inwards, that is self questioning. Beyond that, the book also reveals the diversity of the “I” of a Liscano that inscribes himself as fiction, and at the same time appeals often to self-referentiality, to data recognized as being from the personal life of the public man and also from Uruguay, projecting the desire to wipe off the frontiers between factual and fictional. Therefore, we start from the hypothesis that the stories present in El escritor y el otro are not limited to a testimonial literature neither to a autobiographical literature, but are projected through a script that is assumed to be undecided in terms of gender, in a text that reinvents a life in its words, and outlines the performance of an author and his spectacular image, as a way to mock the writers life and the same speculate form of the own text that he elaborates.

    Nye, Mary Jo

    2007-01-15

    Following along with the development of electron theory and quantum mechanics in the 1910s and 1920s, physical chemists began incorporating these new theories and approaches in their studies of activation energies, transition states, and chemical reactions for simple atomic and molecular systems. Among these chemists was Michael Polanyi, one of the founders of modern chemical dynamics, who collaborated with Henry Eyring in the development in the 1930s of a theory of the activated transition state and absolute reaction rates using potential energy surfaces and a semiempirical methodology. This paper examines the circumstances of their collaborative work, its reception, and its implications for further chemical research.

  14. Genetic advances require comprehensive bioethical debate.

    Science.gov (United States)

    ten Have, Henk A M J

    2003-10-01

    In the popular media and scientific literature, the idea of medical utopia seems to have been revived. Medical science and technology are expected to provide solutions for all kinds of daily problems in human existence. The utopian context and optimistic atmosphere are influencing deeply the bio-ethical debate concerning bio-molecular technologies. They a priori direct this debate towards individual perspectives, emphasizing the benefits among which an autonomous person can make his or her choice, and towards practical applications the potential beneficial effects of which are almost there. It is argued that the concept of "geneticization" is useful for the analysis of the interrelations between genetics, medicine, society, and culture. This concept focuses on conceptual issues--the use of genetic vocabulary to define problems; institutional issues--the emergence of bio-ethics experts; cultural issues--the transformation of individual and social attitudes under the influence of genetic knowledge and technology; and philosophical issues--changing views of human identity, interpersonal relationships, and individual responsibility.

  15. Debates about assisted suicide in Switzerland.

    Burkhardt, Sandra; La Harpe, Romano

    2012-12-01

    Assisted suicide is allowed in 3 states of the United States (Oregon, Washington, Montana) but only if performed by a physician.On the opposite, in Switzerland, at the beginning of the 20th century, the Swiss Penal Code referred to assisted suicide in the context of honor or an unhappy love affair. It was only in 1985 that Exit Deutsche Schweiz (Exit for German-speaking Switzerland) "medically" assisted the first patient to end his life.Even if authorized by the Swiss law upon certain conditions, assisted suicide is subject to debates for ethical reasons. The Swiss Academy of Medical Sciences described directives to guide physicians on this difficult subject.Different studies showed an increase in the number of medical-assisted suicide in Switzerland since the 1990s. Now, this number seems to be quite stable. Assisted suicide is authorized in a few hospitals under strict conditions (especially when returning home is impossible).Thus, according to the Swiss law, any person could perform assisted suicide; this is essentially performed by 3 main associations, using pentobarbital on medical prescription as lethal substance.Generally speaking, the Swiss population is rather in favor of assisted suicide. Among politics, the debate has been tough until 2010, when the Federal Council decided not to modify the Swiss Penal Code concerning assisted suicide.

    Self-organized regular vegetation patterns are widespread and thought to mediate ecosystem functions such as productivity and robustness, but the mechanisms underlying their origin and maintenance remain disputed. Particularly controversial are landscapes of overdispersed (evenly spaced) elements, such as North American Mima mounds, Brazilian murundus, South African heuweltjies, and, famously, Namibian fairy circles. Two competing hypotheses are currently debated. On the one hand, models of scale-dependent feedbacks, whereby plants facilitate neighbours while competing with distant individuals, can reproduce various regular patterns identified in satellite imagery. Owing to deep theoretical roots and apparent generality, scale-dependent feedbacks are widely viewed as a unifying and near-universal principle of regular-pattern formation despite scant empirical evidence. On the other hand, many overdispersed vegetation patterns worldwide have been attributed to subterranean ecosystem engineers such as termites, ants, and rodents. Although potentially consistent with territorial competition, this interpretation has been challenged theoretically and empirically and (unlike scale-dependent feedbacks) lacks a unifying dynamical theory, fuelling scepticism about its plausibility and generality. Here we provide a general theoretical foundation for self-organization of social-insect colonies, validated using data from four continents, which demonstrates that intraspecific competition between territorial animals can generate the large-scale hexagonal regularity of these patterns. However, this mechanism is not mutually exclusive with scale-dependent feedbacks. Using Namib Desert fairy circles as a case study, we present field data showing that these landscapes exhibit multi-scale patterning-previously undocumented in this system-that cannot be explained by either mechanism in isolation. These multi-scale patterns and other emergent properties, such as enhanced resistance to

    2015-01-01

    Unraveling the first migrations of anatomically modern humans out of Africa has invoked great interest among researchers from a wide range of disciplines. Available fossil, archeological, and climatic data offer many hypotheses, and as such genetics, with the advent of genome-wide genotyping and sequencing techniques and an increase in the availability of ancient samples, offers another important tool for testing theories relating to our own history. In this review, we report the ongoing debates regarding how and when our ancestors left Africa, how many waves of dispersal there were and what geographical routes were taken. We explore the validity of each, using current genetic literature coupled with some of the key archeological findings.

    Publishing studies on the relationship between health and pollution provokes reactions and interest in the public opinion involved, the highest national institutions included. This commentary, aroused by a parliamentary debate, which also concerned one of our recent scientific papers published on Environmental Research about the association between congenital anomalies and maternal exposure to atmospheric pollutants in Brindisi (Apulia Region, Southern Italy), aims at contributing to reply the following questions: the type and quality of the data used in the estimates of exposure must be certified by institutional bodies? Adverse health effects in people exposed to pollutants at levels below the law limits can be excluded? Finally, we draw some remarks on measures to protect public health and on the relationship between the work of the researchers of public institutes and administrations.

    Menon, Ravi S

    2012-08-15

    From the earliest fMRI experiments, it was quickly appreciated by those working with BOLD at high field that the signal change originated from visible veins whose spatial localization was relatively coarse ("the macrovasculature"), and smaller vessels ("the microvasculature") that were not individually visible in BOLD images. It was expected that a functional brain imaging technique that was predominantly sensitive to the macrovasculature would not have the same effective resolution as one sensitive to the microvasculature. Elimination of the venous signal and enhancement of the microvascular one offered the tantalizing ability to image columnar and lamellar structures in the brain and distinguished fMRI from its predecessor techniques. This article reviews a brief history of how these signal sources were first identified and separated and some of the controversy associated with the "brain versus vein" debate.

    Full Text Available Academic literature tends to reflect the two main objectives of power-sharing: promoting the construction of sustainable peace and serving to structure the foundations for growth and development of democracy in divided societies. reflecting this, two dimensions and discourses of analysis and evaluation stand out: a classical dimension centred on power-sharing as theory and a normative proposal for democracy in divided societies, and another focused mainly on power-sharing as a meachanism of conflict management. This article aims to introduce the reader to discussions about power-sharing, reviewing and critically analysing power-sharing literature to show its gaps and tensions, as well as suggesting some points where one can continue the debate.

    Full Text Available This review discusses the volume Debating German Heritage, a special issue of the journal Kunstiteaduslikke Uurimusi. This issue focuses heritage and art historical knowledge production in relation to nationalism, containing an introduction and six essays on a variety of subjects related to this main theme. The essays each approach heritage practices in the nineteenth century from different a perspective, ranging from canon formation to heritage preservation efforts at theatres of war. This review takes a closer look at each of the essays and studies the main contribution of the volume to the field of art history and heritage scholarship. Overall, this special issue offers interesting insights in the relationship between the dynamics of heritage preservation, art historical scholarship and nationalism from the point of view of Eastern and Central European scholarship with a ‘German connection’. In all, the essays are invariably well researched, often innovative in their approach and pleasant to read.

  1. Antarctic “quiet” site stirs debate

    Science.gov (United States)

    Simarski, Lynn Teo

    Geophysicists from the United States and New Zealand plan to meet in the coming months to assess the electromagnetic pollution of an Antarctic site especially designated for research. U.S. scientists charge that a satellite Earth station erected apparently inside the preserve by New Zealand's Telecom company could interfere with experiments on the ionosphere and magnetosphere (Eos, April 28, 1992). The Site of Special Scientific Interest at Arrival Heights, the only Antarctic preserve specifically for physical science, is located near the U.S. McMurdo and New Zealand Scott bases.Debate over the Telecom facility inter-twines diplomatic and scientific issues. One question is whether the station violates the Antarctic treaty. Secondly, does it actually impair research at the site—or could it harm future experiments? To deepen the imbroglio, those involved from both nations say that transmissions from sources off-site also interfere with research—raising doubts about how pristine the site really is.

    In the ethical debate on genetic modification (GM), it is common to encounter the claim that some anti-GM argument would also apply an established, ethically accepted technology, and that the anti-GM argument is therefore unsuccessful. The paper discusses whether this argumentative strategy...... transferability of reasons from one case to another; and (iii) it runs the risk of equivocations, especially in cases where the anti-genetic-modification argument relies on gradable features. The paper then shows how these issues play out in three specific Similarity Arguments that can be found in the literature....... Finally, the paper discusses what conclusions we can draw from the fact that genetic modification and established technologies are similar for the ethical status of genetic modification....

  3. The GM foods debate in Europe

    2005-01-01

    The debate on genetically modified (GM) foods has been led on multiple levels in Europe, including such diverse frames of reference as economic policy and international trade, environmental risk, bioethics, consumer protection and food safety. The shifting frames of reference are traced over...... the past three decades, focusing on events leading up to the five year quasi-moratorium on GM foods and its final lifting in 2004. While regulatory problems have been resolved, commercial actors in the food chain have done little to prepare themselves for the actual marketing of GM foods to European...... consumers. Relevant consumer research is reviewed, and a potential way forward for commercial actors is outlined. It is concluded that the conceptualization of GM foods should be turned back on its feet, understanding them as foods and not just as embodiments of technology....

  7. A web of controversies: complexity in the burgess shale debate.

    Science.gov (United States)

    Baron, Christian

    2011-01-01

    Using the Burgess Shale controversies as a case-study, this paper argues that controversies within different domains may interact as to create a situation of "com- plicated intricacies," where the practicing scientist has to navigate through a context of multiple thought collectives. To some extent each of these collectives has its own dynamic complete with fairly negotiated standards for investigation and explanation, theoretical background assumptions and certain peculiarities of practice. But the intellectual development in one of these collectives may "spill over" having far reaching consequences for the treatment of apparently independent epistemic problems that are subject of investigation in other thought collectives. For the practicing scientist it is necessary to take this complex web of interactions into account in order to be able to navigate in such a situation. So far most studies of academic science have had a tendency to treat the practicing scientist as members of a single (enclosed) thought collective that stands intellectually isolated from other similar entities unless the discipline was in a state of crisis of paradigmatic proportions. The richness and complexity of Burgess Shale debate shows that this encapsulated kind of analysis is not enough.

  9. Die teologiese debat: Die waarde of betekenis daarvan

    1994-01-01

    Full Text Available The theological debate: Its value and significance With negotiation and debate being the buzz-words of our day, it is of some value to explore, even if only superficially, the structure and tendency of the theological debate in the history of the church. In the theological debate the cardinal issue is the Word of God which determines the word of man. In this light the theological debate can be distinguished as both an internal debate within the church arid an external debate with those outside the church. The substance of the debate is determined largely by the question of the content and significance of the Word of God Since the Word of God is an absolute norm, the theological debate tends to become a statement and, in many cases, does not develop iruo an exchange of ideas or points of view. The theological debate, with its apologetic, explanatory and didactic elements, is however a necessary element in church life. Within its limits it can be a stimulating expression of the faith of the church.

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

    Oerlemans, A J M; van Hoek, M E C; van Leeuwen, E; van der Burg, S; Dekkers, W J M

    2013-09-01

    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.

  12. Frames and comparators: How might a debate on synthetic biology evolve?

    Science.gov (United States)

    Torgersen, Helge; Schmidt, Markus

    2013-04-01

    A stimulated early public debate is frequently advocated when introducing an emerging technology like synthetic biology (SB). To debate a still quite abstract technology, participants functionally need a frame that determines which arguments are legitimate and which issues are relevant. Often, such frames are based on previous debates over other novel technologies. Three technologies currently provide frames for discussing SB: (green) biotechnology, nanotechnology and information technology. In the biotechnology debate, risk has long been emphasised over economic benefits. More recently, nanotechnology has been referred to mostly in terms of benefits, while risks tended to be an issue for scientific discourses. This has frequently been related to the many outreach activities around nanotechnology. Information technology, finally, has retained the image of being 'cool' and useful on a personal level. The technology itself is taken for granted and only the consequences of particular applications have been up for discussion. Upstream engagement exercises in SB will have to consider the comparator chosen more diligently, because it might influence the debate on SB 'out there' in the long run.

    2016-09-13

    The 2015 Varsity Medical Ethics debate convened upon the motion: "This house believes nootropic drugs should be available under prescription". This annual debate between students from the Universities of Oxford and Cambridge, now in its seventh year, provided the starting point for arguments on the subject. The present article brings together and extends many of the arguments put forward during the debate. We explore the current usage of nootropic drugs, their safety and whether it would be beneficial to individuals and society as a whole for them to be available under prescription. The Varsity Medical Debate was first held in 2008 with the aim of allowing students to engage in discussion about ethics and policy within healthcare. The event is held annually and it is hoped that this will allow future leaders to voice a perspective on the arguments behind topics that will feature heavily in future healthcare and science policy. This year the Oxford University Medical Society at the Oxford Union hosted the debate.

  14. Enhancing learning with the social media: student teachers’ perceptions on Twitter in a debate activity

    2015-01-01

    Full Text Available This paper presents research focused on the educational experience of students using the microblogging platform Twitter for debate activities in three groups in different teacher education programmes at the University of the Balearic Islands, Spain. The implementation of this technology-based task in a face-to-face class was introduced as an innovative experience as a way of enhancing student learning and fostering participation in the context of formal learning. The educational objectives of these activities, besides working on the topics of the debate, were to empower student teachers’ Personal Learning Environments, engage student participation and enhance their use of social media and mobile devices for learning. Student perceptions were assessed by means of a questionnaire completed by them at the end of the courses. Tweets related to the debate were also collected in order to obtain some statistical data on student participation. Data collected allowed the researchers to observe student teacher engagement with the use of Twitter for the debate activity and its impact on their learning and understanding of the debate topic. Results also showed positive perceptions towards the use of social media in education and students’ willingness for future use, learning opportunities from Twitter and the use of mobile technology were also envisioned. Finally, conclusions argue the implications for practice of the current study and highlight some issues for further research, such as the exploration of new and innovative uses for teachers’ professional development and the empowerment of new activities and habits in learning on the move.

    2016-02-01

    Full Text Available The paper is part of wider research into the status of explanation in the debate on the scientific status of anthropology – wherein one of the key assumptions is that there is a strong correlation between theoretical and methodological structures which would make them inseparable, and that explanation or explanatory potential, is the point of convergence which can be used to test for the possibility of separating theoretical and methodological structures in the first place. To test this idea, a line of debate between methodological holism and methodological individualism – one of the longest running and most complex debates in the social sciences and humanities – was considered. The historical background of the debate has been highlighted, and its relevancy and implications in the controversy about the explanatory capacity and scientific status of sociocultural anthropology.

  17. Did Ptolemy make novel predictions? Launching Ptolemaic astronomy into the scientific realism debate.

    Science.gov (United States)

    Carman, Christián; Díez, José

    2015-08-01

    The goal of this paper, both historical and philosophical, is to launch a new case into the scientific realism debate: geocentric astronomy. Scientific realism about unobservables claims that the non-observational content of our successful/justified empirical theories is true, or approximately true. The argument that is currently considered the best in favor of scientific realism is the No Miracles Argument: the predictive success of a theory that makes (novel) observational predictions while making use of non-observational content would be inexplicable unless such non-observational content approximately corresponds to the world "out there". Laudan's pessimistic meta-induction challenged this argument, and realists reacted by moving to a "selective" version of realism: the approximately true part of the theory is not its full non-observational content but only the part of it that is responsible for the novel, successful observational predictions. Selective scientific realism has been tested against some of the theories in Laudan's list, but the first member of this list, geocentric astronomy, has been traditionally ignored. Our goal here is to defend that Ptolemy's Geocentrism deserves attention and poses a prima facie strong case against selective realism, since it made several successful, novel predictions based on theoretical hypotheses that do not seem to be retained, not even approximately, by posterior theories. Here, though, we confine our work just to the detailed reconstruction of what we take to be the main novel, successful Ptolemaic predictions, leaving the full analysis and assessment of their significance for the realist thesis to future works.

    This paper discusses the two main issues of the so called quantum debate, that started in 1927 with the famous Bohr-Einstein controversy; namely non-separability and the projection postulate. Relevant interpretations and formulations of quantum mechanics are critically analyzed in the light of the said issues. The treatment is focused chiefly on fundamental points, so that technical ones are practically not dealt with here. (Author) 20 refs.

  19. The Debate on the Moral Responsibilities of Online Service Providers.

    Science.gov (United States)

    Taddeo, Mariarosaria; Floridi, Luciano

    2016-12-01

    Online service providers (OSPs)-such as AOL, Facebook, Google, Microsoft, and Twitter-significantly shape the informational environment (infosphere) and influence users' experiences and interactions within it. There is a general agreement on the centrality of OSPs in information societies, but little consensus about what principles should shape their moral responsibilities and practices. In this article, we analyse the main contributions to the debate on the moral responsibilities of OSPs. By endorsing the method of the levels of abstract (LoAs), we first analyse the moral responsibilities of OSPs in the web (LoAIN). These concern the management of online information, which includes information filtering, Internet censorship, the circulation of harmful content, and the implementation and fostering of human rights (including privacy). We then consider the moral responsibilities ascribed to OSPs on the web (LoAON) and focus on the existing legal regulation of access to users' data. The overall analysis provides an overview of the current state of the debate and highlights two main results. First, topics related to OSPs' public role-especially their gatekeeping function, their corporate social responsibilities, and their role in implementing and fostering human rights-have acquired increasing relevance in the specialised literature. Second, there is a lack of an ethical framework that can (a) define OSPs' responsibilities, and (b) provide the fundamental sharable principles necessary to guide OSPs' conduct within the multicultural and international context in which they operate. This article contributes to the ethical framework necessary to deal with (a) and (b) by endorsing a LoA enabling the definition of the responsibilities of OSPs with respect to the well-being of the infosphere and of the entities inhabiting it (LoAFor).

  1. The debate on the relationship between globalization, poverty and inequality: A critical overview

    Directory of Open Access Journals (Sweden)

    Vicente Valentim

    2016-11-01

    Full Text Available On this theoretical article, I critically present the ongoing debate on the relationship between globalization, poverty and inequality. To do so, I rely on the typology put forward by Held & McGrew (2007, which divides scholars between two main approaches: the globalists and the skeptics. Among the first approach, one can then distinguish between neoliberal globalists and transformationalist globalists. Among the second one, one can distinguish between realist skeptics and Marxist skeptics. I go through the most important thinkers of each of these four perspectives, summing up the most influential arguments put forward to support their view. By grouping the views of these scholars, I show similarities and differences between the four perspectives and thus contribute to making the debate more clear. In a further section, I critically assess these arguments, identifying some of their strengths and shortcomings.

  2. Public health, science, and policy debate: being right is not enough.

    Science.gov (United States)

    Camargo, Kenneth; Grant, Roy

    2015-02-01

    Public health is usually enacted through public policies, necessitating that the public engage in debates that, ideally, are grounded in solid scientific findings. Mistrust in science, however, has compromised the possibility of deriving sound policy from such debates, partially owing to justified concerns regarding undue interference and even outright manipulation by commercial interests. This situation has generated problematic impasses, one of which is the emergence of an anti-vaccination movement that is already affecting public health, with a resurgence in the United States of preventable diseases thought to have been eradicated. Drawing on British sociologist Harry Collins' work on expertise, we propose a theoretical framework in which the paralyzing, undue public distrust of science can be analyzed and, it is hoped, overcome.

A seguir, traça-se breve perfil da formação intelectual de Say a fim de apresentar sua visão sobre o funcionamento dos mercados. Na continuação, examina-se a perspectiva histórica de Sismondi em sua crítica da ortodoxia clássica, bem como sua versão para a tendência do sistema capitalista à superprodução. Nas duas últimas partes, recuperam-se os comentários recíprocos de Say e Sismondi a respeito de suas divergências teóricas sobre os limites da acumulação de capital.This paper deals with the debate happened between Say and Sismondi regarding the possibility of a general glut. The first section describes the historical context of the first decades of nineteenth century continental Europe, focusing on the French industrialization experience vis-à-vis the British leadership in this field. Next, a brief intellectual profile of the evolution of Say's thought is made in order to present his vision about the proper working of markets. After that, the historical approach used by Sismondi in his criticism of classical orthodoxy is examined, as well as his own version to the capitalistic system inner tendency towards overproduction. The last two sections retrieve the exchange between Say and Sismondi over their theoretical disagreements on the limits to capital accumulation.

  8. The conscientious objection: debate on emergency contraception.

    Montanari Vergallo, G; Zaami, S; Di Luca, N M; Marinelli, E

    2017-01-01

    The authors discuss the emergency contraception (EC) topic, assessing scientific and ethical aspects. The almost totality of the studies carried out tends to report on the use of drugs as an emergency measure to prevent pregnancy. However, it is not yet completely excluded that emergency contraceptives can induce medical abortion. The debate on side effects of EC continues to be a highly emotional and controversial issue both for advocates who believe they will lower considerably the number of unintended pregnancies and abortions, and for opponents who believe that using emergency contraception amounts to an abortion. This latter hypothesis highlights the conflicting aspect of the conscientious objection to abortion of physicians and pharmacists. This research work is aimed at investigating the emergency contraception issue, paying particular attention to the medico-legal and regulatory aspects of this subject. Particularly, the authors focus on the conscientious objection in order to assess, if any, legal protection for physicians and pharmacists who claim a right to conscientious objection. Inappropriate use of EC could be resolved through a registry of user. This registry, of course, would not have the intention of persecution, but would only serve to detect possible cases of subjugation, exploitation and harassment.

  10. Shaping AGU's contributions to policy debate

    Science.gov (United States)

    Morgan, M. Granger; Patwardhan, Anand

    In their Forum piece in the April 9 issue of Eos, Kaula and Anderson paint an unrealistically stark choice for the roles AGU might play in policy debates that substantially involve geophysical science. On the one hand is the antiseptic model of AGU-above-the-policy-fray: the aloof provider of geophysical facts from the literature. On the other hand is the model of AGU-as-policy-advocate: blending geophysical knowledge with value judgements in order to argue for specific policy actions in the political trenches. The problem with the first model is that the form assumed by most geophysical facts in the literature is rather distant from the needs of policy makers. Thus, the facts are easily overlooked in the face of pressing short-term political agendas. The problem with the second model is that AGU is a professional society comprised of scientists who hold many different value orientations. Any particular set of values adopted in a piece of political advocacy is likely to be at odds with many AGU members.

    Full Text Available resumo Este trabalho aponta aspectos do debate em torno da construção da nação e da nacionalidade brasileiras, ao longo das primeiras décadas do século XX, na medida em que tais discussões envolvem temas relacionados ao urbanismo enquanto princípio e ao papel das cidades no país que se pretendia construir. Naquele momento, urbanismo se opunha a ruralismo, agrarismo e outras correntes de pensamento que viam com maus olhos os grandes centros urbanos. De maneira geral, as posições ideológicas em pauta na época debatiam-se entre termos contraditórios: de um lado, a aspiração do moderno, com suas referências urbanas, europeias e norte-americanas; de outro, a busca do caráter nacional brasileiro, em que predominariam elementos tradicionais e rurais. Urbanismo e antiurbanismo são elementos que podem ilustrar tais dilemas, evidenciando limites ideológicos presentes no momento da introdução da urbanística moderna no Brasil.

  14. Systems in Context - On the outcome of the Habermas/Luhmann-debate

    Directory of Open Access Journals (Sweden)

    Poul Kjaer

    2006-09-01

    Full Text Available Usually regarded as a 1970s phenomenon, this article demonstrates that the debate between Jürgen Habermas and Niklas Luhmann continued until Luhmann’s death in 1998, and that the development of the two theorists’ positions during the 1980s and 1990s was characterised by convergence rather than by divergence. In the realm of legal theory, the article suggests, convergence advanced to the extent that Habermas’ discourse theory may be characterised as a normative superstructure to Luhmann’s descriptive theory of society. It is further shown that the debate’s result was an almost complete absorption of Habermas’ theory by Luhmann’s systems theoretical complex – an outcome facilitated by Luhmann’s deliberate translation of central Habermasian concepts into systems theoretical concepts. The article argues that both the debate and Habermas’ conversion were made possible because not only Habermas’ but also Luhmann’s work can be considered a further development of the German idealist tradition. What Luhmann did not acknowledge was that this manoeuvre permitted the achievement of Habermas’ normative objectives; nor did he notice that it could eradicate a central flaw in the system theoretical construction, by allowing the context within which distinctions are drawn to be mapped ‐ an issue of pivotal importance for grasping relationships between different social systems, and coordinating them, via the deployment of legal instruments.

    Following some political maneuvering, a new debate on the future of nuclear deterrence is about to resurface. And a first deadline has been set by the need to restore the strategic balance between the United States and Russia before the START Treaty ends on 5 December 2009, as well as by preparation for the next NPT Review Conference. Perception of the main threat has changed, but so have concepts of deterrence. Far from outmoded, deterrence forms part of a broader vision in which realism has the edge over idealism. (author)

    Murray, C.S.; El-Genk, M.S.

    1994-02-01

    A low voltage/high current switch refer-red as ``Cs-Ba tacitron`` is studied for use as a dc to ac inverter in high temperature and/or ionizing radiation environments. The operational characteristics of the Cs-Ba tacitron as a switch were investigated experimentally in three modes: (a) breakdown mode, (b) I-V mode, and (c) current modulation mode. Operation parameters measured include switching frequencies up to 20 kHz, hold-off voltages up to 200 V, current densities in excess of 15 A/CM{sup 2}, switch power density of 1 kW/cm{sup 2}, and a switching efficiency in excess of 90 % at collector voltages greater than 30 V. Also, if the discharge current is circuit limited to a value below the maximum thermal emission current density, the voltage drop is constant and below 3 V.

  5. Revisiting the ‘disaster and development’ debate – Toward a broader understanding of macroeconomic risk and resilience

    Directory of Open Access Journals (Sweden)

    Junko Mochizuki

    2014-01-01

    Full Text Available Debate regarding the relationship between socioeconomic development and natural disasters remains at the fore of global discussions, as the potential risk from climate extremes and uncertainty pose an increasing threat to developmental prospects. This study reviews statistical investigations of disaster and development linkages, across topics of macroeconomic growth, public governance and others to identify key challenges to the current approach to macro-level statistical investigation. Both theoretically and qualitatively, disaster is known to affect development through a number of channels: haphazard development, weak institutions, lack of social safety nets and short-termism of our decision-making practices are some of the factors that drive natural disaster risk. Developmental potentials, including the prospects for sustainable and equitable growth, are in turn threatened by such accumulation of disaster risks. However, quantitative evidence regarding these complex causality chains remains contested due to several reasons. A number of theoretical and methodological limitations have been identified, including the use of GDP as a proxy measurement of welfare, issues with natural disaster damage reporting and the adoption of ad hoc model specifications and variables, which render interpretation and cross-comparison of statistical analysis difficult. Additionally, while greater attention is paid to economic and institutional parameters such as GDP, remittance, corruption and public expenditure as opposed to hard-to-quantify yet critical factors such as environmental conditions and social vulnerabilities. These are gaps in our approach that hamper our comprehensive understanding of the disaster-development nexus. Important areas for further research are identified, including recognizing and addressing the data constraints, incorporating sustainability and equity concerns through alternatives to GDP, and finding novel approaches to examining the

    2005-01-01

    Previous research has demonstrated the potential for work-related stress associated with employment in the emergency service field. However, little research has considered effective interventions that may be used to mediate the effects of this work-related stress. Critical Incident Stress Debriefing (CISD) is one intervention that is currently employed with emergency service workers. However, the efficacy of this intervention is currently the source of much debate. The present discussion reviews the available literature regarding the effectiveness of CISD for use with emergency service workers and concludes that at this time, for this population, the call for the removal of current programs using CISD is unwarranted.

  8. Issues in the Recognition versus Disclosure of Financial Information Debate

    Directory of Open Access Journals (Sweden)

    Novak Aleš

    2016-12-01

    Full Text Available Empirical evidence from the academic literature on capital market effects of financial information placement (i.e., recognition on the face of the primary financial statements versus disclosure in the notes to the financial statements is not straightforward. Therefore, the purpose of this paper is to contribute to the recognition versus required disclosure debate in a standard-setting context by exploring possible reasons for perceived differences between recognized and disclosed amounts. These differences, in our view, arise due to demonstrated auditors’ greater tolerance for misstatement in disclosed amounts, allowed noncompliance with disclosure requirements even in strong enforcement regimes, lesser care that preparers of financial statements devote to disclosures relative to recognized items as well as behavioural factors and differential processing costs related to the users of financial information. We believe that these arguments strengthen the case for the general preference for the recognition of financial information in the standard-setting context. The original scientific contribution of this paper is to systematically identify the reasons for the differences between recognized and disclosed amounts in financial statements. As such, this paper may provide a suitable basis for the justification of certain conceptual changes in the field of international accounting standards that are currently underway.

  9. Debating "the Social": Towards a Critique of Sociological Nostalgia

    Directory of Open Access Journals (Sweden)

    Anthony Elliott

    2012-03-01

    Full Text Available Although sociology can be commonsensically and parsimoniously defined as the study of society, the problems of defining such terms as ‘society’, ‘the social’, and ‘the social system’ remain an ongoing irritant of sociological theory. In addition to these traditional conceptual problems, there is currently a strong sense that ‘society’ as an empirical reality and ‘society’ as a concept are in crisis. Given the contemporary view of ‘the end of the social’ there is also manifestly a potent and nostalgic interest in the past as a time of comforting solidarity and meaningfulness. To clarify this debate, we start by making a distinction between three approaches to society, namely structure, solidarity and creation. Nostalgia hinges around the certainties that followed from reliable social structures, and from the comfort of community. We illustrate these forms of nostalgia through an examination of the social philosophy of Alasdair MacIntyre. Recognizing that his criticisms of the loss of virtue represent a powerful indictment of modernity, we argue that past societies were also fractured by moral discord. More importantly, MacIntyre rules out the possibility of moral re-invention by excluding the rise of human rights as a moral framework. In conclusion, the forms of social creativity may not enjoy the ‘sticky’ solidarity of the past, but they do testify Georg Simmel’s idea of the social (Vergesellschaftung.

    2015-04-01

    Full Text Available The fact that the United Nations (UN Trafficking Protocol is not an autochthonous product of the Brazilian political system has resulted in its being brought into that system as a ‘floating signifier’: something that does not point to any actual object or agreed upon meaning.[1] People who wish to criminalise prostitution have attempted to bend the Protocol in that direction while prostitutes’ rights groups have used it to critique current Brazilian laws, emphasising the need to distinguish migration for voluntary, consensual sex work from trafficking. Groups concerned with organ trafficking (a crime for which there are practically no proven cases in Brazil have managed to push their banner to the fore in the trafficking debate. Meanwhile, Brazil’s long-established and relatively successful anti-slave labour movement has been loath to ‘change their brand’, having already gained a considerable degree of institutionalisation prior to Brazil’s ratification of the Protocol in 2004.

  11. Gold or green: the debate on open access policies.

    Science.gov (United States)

    Abadal, Ernest

    2013-09-01

    The movement for open access to science seeks to achieve unrestricted and free access to academic publications on the Internet. To this end, two mechanisms have been established: the gold road, in which scientific journals are openly accessible, and the green road, in which publications are self-archived in repositories. The publication of the Finch Report in 2012, advocating exclusively the adoption of the gold road, generated a debate as to whether either of the two options should be prioritized. The recommendations of the Finch Report stirred controversy among academicians specialized in open access issues, who felt that the role played by repositories was not adequately considered and because the green road places the burden of publishing costs basically on authors. The Finch Report's conclusions are compatible with the characteristics of science communication in the UK and they could surely also be applied to the (few) countries with a powerful publishing industry and substantial research funding. In Spain, both the current national legislation and the existing rules at universities largely advocate the green road. This is directly related to the structure of scientific communication in Spain, where many journals have little commercial significance, the system of charging a fee to authors has not been adopted, and there is a good repository infrastructure. As for open access policies, the performance of the scientific communication system in each country should be carefully analyzed to determine the most suitable open access strategy.

  12. Physician assisted suicide: the great Canadian euthanasia debate.

    Science.gov (United States)

    Schafer, Arthur

    2013-01-01

    A substantial majority of Canadians favours a change to the Criminal Code which would make it legally permissible, subject to careful regulation, for patients suffering from incurable physical illness to opt for either physician assisted suicide (PAS) or voluntary active euthanasia (VAE). This discussion will focus primarily on the arguments for and against decriminalizing physician assisted suicide, with special reference to the British Columbia case of Lee Carter vs. Attorney General of Canada. The aim is to critique the arguments and at the same time to describe the contours of the current Canadian debate. Both ethical and legal issues raised by PAS are clarified. Empirical evidence available from jurisdictions which have followed the regulatory route is presented and its relevance to the slippery slope argument is considered. The arguments presented by both sides are critically assessed. The conclusion suggested is that evidence of harms to vulnerable individuals or to society, consequent upon legalization, is insufficient to support continued denial of freedom to those competent adults who seek physician assistance in hastening their death.

  13. Terms of the debate on the format and structure of visual memory.

    Science.gov (United States)

    Suchow, Jordan W; Fougnie, Daryl; Brady, Timothy F; Alvarez, George A

    2014-10-01

    Our ability to actively maintain information in visual memory is strikingly limited. There is considerable debate about why this is so. As with many questions in psychology, the debate is framed dichotomously: Is visual working memory limited because it is supported by only a small handful of discrete "slots" into which visual representations are placed, or is it because there is an insufficient supply of a "resource" that is flexibly shared among visual representations? Here, we argue that this dichotomous framing obscures a set of at least eight underlying questions. Separately considering each question reveals a rich hypothesis space that will be useful for building a comprehensive model of visual working memory. The questions regard (1) an upper limit on the number of represented items, (2) the quantization of the memory commodity, (3) the relationship between how many items are stored and how well they are stored, (4) whether the number of stored items completely determines the fidelity of a representation (vs. fidelity being stochastic or variable), (5) the flexibility with which the memory commodity can be assigned or reassigned to items, (6) the format of the memory representation, (7) how working memories are formed, and (8) how memory representations are used to make responses in behavioral tasks. We reframe the debate in terms of these eight underlying questions, placing slot and resource models as poles in a more expansive theoretical space.

    2014-12-22

    Several recent publications reflect debate on the issue of "endocrine disrupting chemicals" (EDCs), indicating that two seemingly mutually exclusive perspectives are being articulated separately and independently. Considering this, a group of scientists with expertise in basic science, medicine and risk assessment reviewed the various aspects of the debate to identify the most significant areas of dispute and to propose a path forward. We identified four areas of debate. The first is about the definitions for terms such as "endocrine disrupting chemical", "adverse effects", and "endocrine system". The second is focused on elements of hormone action including "potency", "endpoints", "timing", "dose" and "thresholds". The third addresses the information needed to establish sufficient evidence of harm. Finally, the fourth focuses on the need to develop and the characteristics of transparent, systematic methods to review the EDC literature. Herein we identify areas of general consensus and propose resolutions for these four areas that would allow the field to move beyond the current and, in our opinion, ineffective debate.

  15. Is It Necessary to Lie to Win a Controversial Public Debate? An Answer from Sociophysics

    Science.gov (United States)

    Galam, Serge

    Controversial public debates driven by incomplete scientific data where nobody can claim absolute certainty, due to the current state of scientific knowledge, are studied. To adopt a cautious balanced attitude based on clear but inconclusive data appears to be a lose-out strategy. In contrast overstating arguments with incorrect claims which cannot be scientifically refuted appears to be necessary but not sufficient to eventually win a public debate. The underlying key mechanisms of these puzzling and unfortunate conclusions are identified using the Galam Unifying Frame (GUF) of opinion dynamics . It reveals that the existence of inflexible agents and their respective proportions are the instrumental parameters to determine the faith of incomplete scientific data in public debates. Acting on one's own inflexible proportion modifies the topology of the flow diagram, which in turn can make irrelevant the value of initial support. On the contrary focusing on open-minded agents may be useless given some topologies. Accordingly, the inflexibles rather than the data are found to drive the opinion of the population. The results shed a new but disturbing light on designing adequate strategies to win a public debate. The cases of global warming is briefly discussed.

    Zatoński, Mateusz; Hawkins, Benjamin; McKee, Martin

    2016-12-23

    Industry lobbying remains an obstacle to effective health-oriented alcohol policy. In 2013, an increase in excise tax on spirits was announced by the Polish government. This article presents a qualitative analysis of the public debate that ensued on the potential economic, health and social effects of the policy. It focuses on how competing groups, including industry actors, framed their position and sought to dominate the debate. Online archives of five Polish national newspapers, two spirits trade associations, and parliamentary and ministerial archives were searched. A thematic content analysis of the identified sources was conducted. The overall findings were compared with existing research on the framing of the Minimum Unit Pricing (MUP) debate in the UK. A total of 155 sources were analysed. Two main frames were identified: health, and economic The spirits industry successfully promoted the economic frame in their own publications and in the media. The debate was dominated by arguments about potential growth of the grey market and losses in tax revenue that might result from the excise tax increase. The framing of the debate in Poland differed from the framing of the MUP debate in the United Kingdom. The Polish public health community was unsuccessful in making health considerations a significant element of the alcohol policy debate. The strategies pursued by UK health advocates offer lessons for how to make a more substantial impact on media coverage and promote health-oriented legislation.

    In this paper, we present the design and experimental verification of an amperometric CMOS-based sensor with a current integrator and a 1.2 × 2.05 µm2 bacterial-sized microelectrode array for high-sensitivity bacterial counting. For high-sensitivity bacterial counting with a sufficient signal-to-noise ratio (SNR), noise must be reduced because bacterial-sized microelectrodes can handle only a low current of the order of 100 pA. Thus, we implement a current integrator that is highly effective for noise reduction. Furthermore, for the first time, we use the current integrator in conjunction with the bacterial-sized microelectrode array. On the basis of the results of the proposed current integration, we successfully reduce noise and achieve a high SNR of 30.4 dB. To verify the effectiveness of the proposed CMOS-based sensor, we perform two-dimensional counting of microbeads, which are almost of the same size as bacteria. The measurement results demonstrate successful high-sensitivity two-dimensional (2D) counting of microbeads with a high SNR of 27 dB.

  1. Epistemic values in the Burgess Shale debate.

    Science.gov (United States)

    Baron, Christian

    2009-12-01

    Focusing primarily on papers and books discussing the evolutionary and systematic interpretation of the Cambrian animal fossils from the Burgess Shale fauna, this paper explores the role of epistemic values in the context of a discipline (paleontology) striving to establish scientific authority within a larger domain of epistemic problems and issues (evolutionary biology). The focal point of this analysis is the repeated claims by paleontologists that the study of fossils gives their discipline a unique 'historical dimension' that makes it possible for them to unravel important aspects of evolution invisible to scientists who study the extant biosphere. The first part of the paper explores the shifting of emphasis in the writings of paleontologists between two strategies that employ opposing views on the classical positivist and physicalist ideal of science. The second part analyzes paleontologists' claims of privileged access to life's historical dimension in a situation where a theoretical upheaval occurring independent of the epistemical problem at hand completely shifts the standards for evaluating the legitimacy of various knowledge claims. Though the various strategies employed in defending the privileged historical perspective of paleontology have been disparate and, to an extent contradictory, each impinges on the acceptance of a specific epistemic ideal or set of values and success or failure of each depends on the compatibility of this ideal with the surrounding community of scientists.

    Full Text Available This paper examines the evolution of debates about territorial reforms in Romania in the first two decades after the fall of Communism. It suggests that the debate was shaped mainly by the choices made by political elites in positioning their parties in relation to ‘post-Communism’ and the ‘Hungarian issue’. Critically, territorial reform rapidly ceased to be a tradable political asset in coalition building for the Democratic Union of Hungarians (UDMR. In recent years debate about territorial reforms has been influenced more heavily by exogenous factors (notably the desire to gain accession to the EU.

    To increase the excitement for the astronomy unit and to expose the subject in all of its weird glory, students debate each other in a bracket style tournament defending their idea of the coolest object in the universe. At the start of May, causing the name of this event to be called May Madness, students choose an object or concept in the universe to research and construct an opening argument on how it is the coolest object in the universe. Every student in the eighth grade selects an object and proceeds to debate its attributes in a head-to-head competition leading to a class winner. The class winners then debate in front of the grade with celebrity guest judges. In the four minute debate, two students defend, cross examine, and construct a rebuttal for their chosen object.

  15. Debate on tourism in postmodernism and beyond

    2014-01-01

    Full Text Available The nexus between globalization and tourism has been established whereas postmodernism imprints features on the current and future society. Seen as a result of revolutions (technological, behavioural, philosophical, economic in society and civilizations, postmodernism can be perceived as an adjustment to new conditions involving changes in all fields, ultimately triggering changes in the vision of current civilization, individual's mentality, perception and behaviour, management of resources, adaptation to environmental alterations and, last but not least, converting tourism from an economic activity into a social and leisure lifestyle, from a complementary necessity into a basic need associated with the right of free movement. We therefore addressed forms and types of tourism and their placement on the new trend in accordance with the change in mentality, perception, behaviour, taste, needs and expectations of providers and consumers. Since niche tourism has already been developed by expressing the multiple perspectives of postmodernism, the aim of our paper is to explore the many possibilities to develop niche tourism and prove that it is indeed the future of tourism in postmodern times as supple structure particularized on narrow tourist-oriented markets, focusing on the identity, authenticity and uniqueness of place, experiential and active-participative tourism products. Our analysis also results in stating several ground features for the future well-be­ing of niche tourism. Identity and not the extravagance prevails and going back to simple is encouraged. However, if we dare to look beyond postmodernism the concluding remarks highlight the prevalence of inherence than conspicuousness in tourism practice given the continuous movement of population (migration, travelling for work in contrast with the obvious monopoly of digitalization and technology that transform a large share of consumers from active travellers to passive virtual tourists

    Full Text Available The influence of neurolinguistic applications on second language pedagogy has often been a controversial subject of dispute. As such, researchers in this field have faced with some blurred and conflicting views in terms of the pedagogical applicability of neurological discoveries for second language instruction. In light of this research-based concern, the current short paper attempts to review the related issues and refocus the current direction of the neurolinguistic-second language pedagogy debate. The paper also concludes with some suggestions made in favor of an alternative neurolinguistic outlook for L2 researchers.

    The current debate concerning the population dynamics of Sub-Saharan Africa is reviewed. The author describes the present demographic situation and the potential for future high rates of population growth. He also discusses Africa's resource potential and its current low levels of population density as well as the growing demands in certain quarters for population control policies. He concludes that much of the demand for population control comes from those who benefit from a world economy that is dominated by the developed market-economy countries, and that a workable solution to population problems in Africa can only come about if the inequalities between rich and poor countries are resolved.

  18. Methylprednisolone for acute spinal cord injury:an increasingly philosophical debate

    Christian A. Bowers; Bornali Kundu; Gregory W. J. Hawryluk

    2016-01-01

    Following publication of NASCIS II, methylprednisolone sodium succinate (MPSS) was hailed as a breakthrough for patients with acute spinal cord injury (SCI). MPSS use for SCI has since become very controversial and it is our opinion that additional evidence is unlikely to break the stalemate amongst cli-nicians. Patient opinion has the potential to break this stalemate and we review our recent ifndings which reported that spinal cord injured patients informed of the risks and beneifts of MPSS reported a prefer-ence for MPSS administration. We discuss the implications of the current MPSS debate on translational research and seek to address some misconceptions which have evolved. As science has failed to resolve the MPSS debate we argue that the debate is an increasingly philosophical one. We question whether SCI might be viewed as a serious condition like cancer where serious side effects of therapeutics are tolerated even when beneifts may be small. We also draw attention to the similarity between the side effects of MPSS and isotretinoin which is prescribed for the cosmetic disorder acne vulgaris. Ultimately we question how patient autonomy should be weighed in the context of current SCI guidelines and MPSS’s status as a his-torical standard of care.

  19. Social media and medical professionalism: rethinking the debate and the way forward.

    Science.gov (United States)

    Fenwick, Tara

    2014-10-01

    This Perspective addresses the growing literature about online medical professionalism. Whereas some studies point to the positive potential of social media to enhance and extend medical practice, the dominant emphasis is on the risks and abuses of social media. Overall evidence regarding online medical professionalism is (as with any new area of practice) limited; however, simply accumulating more evidence, without critically checking the assumptions that frame the debate, risks reinforcing negativity toward social media. In this Perspective, the author argues that the medical community should step back and reconsider its assumptions regarding both professionalism and the digital world of social media. Toward this aim, she outlines three areas for critical rethinking by educators and students, administrators, professional associations, and researchers. First she raises some cautions regarding the current literature on using social media in medical practice, which sometimes leaps too quickly from description to prescription. Second, she discusses professionalism. Current debates about the changing nature and contexts of professionalism generally might be helpful in reconsidering notions of online medical professionalism specifically. Third, the author argues that the virtual world itself and its built-in codes deserve more critical scrutiny. She briefly summarizes new research from digital studies both to situate the wider trends more critically and to appreciate the evolving implications for medical practice. Next, the author revisits the potential benefits of social media, including their possibilities to signal new forms of professionalism. Finally, the Perspective ends with specific suggestions for further research that may help move the debate forward.

Destacam-se as feições tomadas pelo debate tanto na maneira implícita como ele se apresenta na disputa entre modernidade e pós-modernidade, envolvendo autores como Lyotard e Habermas, quanto na emergência de um "senso comum planetário", em que se naturalizam os processos e estruturas que definem um destino e horizonte comum para a humanidade, mas à luz das diferenças e desigualdades que conformam as especificidades dos espaços e das posições sociais no mundo contemporâneo. Deste modo, são discutidas as potencialidades analíticas de categorias como modernidade-mundo, situação, entre outras, para fazer frente ao desafio das disciplinas socioantropológicas na explicação e interpretação de realidades em que o global, o nacional e o local se interpenetram mutuamente.The text recaptures the different stage of perception in relation to the problematic of the globalization on social sciences, since the 80's.

  6. Life and death before birth: 4D ultrasound and the shifting frontiers of the abortion debate.

    Science.gov (United States)

    Savell, Kristin

    2007-08-01

    The development of 4D ultrasound technology has democratised fetal imagery by offering direct visual access to realistic images of the fetus in utero. These images, which purport to show a responsive being capable of complex behaviour, have renewed debate about the personhood of the fetus and the adequacy of current abortion regulation. This article considers recent abortion law reform initiatives in the United Kingdom and the United States and observes two shifts in the frontiers of these debates. The first concerns a shift from viability to sentience as a criterion of legal significance. The second concerns a shift toward constructing abortion in terms of feticide as distinct from the termination of pregnancy. Both strategies seek to deploy morphological similarities between the sentient fetus and newborn baby as a basis for extending law's dominion over the fetus.

    The end-stage cardiomyopathy is an increasing worldwide problem. Cardiac transplantation lacks sufficient donors to treat all patients, and there is thus debate about alternative strategies. The use of left ventricular assist devices for long-term support is increasing with a positive impact on patient survival. Although there is an ongoing debate regarding the risks and benefits of maintaining pulsatile flow during long-term ventricular assist device support, there has been a significant move towards implantation of continuous flow devices due to the lower surgical morbidity and better long-term reliability of these pumps. The following is a review of the literature on continuous and pulsatile flow for long-term support. Starting from the definition of flow, we analyze the current evidence and consider gastrointestinal complications.

  8. American biofutures: ideology and utopia in the Fukuyama/Stock debate.

    Science.gov (United States)

    Ashcroft, R E

    2003-02-01

    Francis Fukuyama, in his Our Posthuman Future, and Gregory Stock, in his Redesigning Humans, present competing versions of the biomedical future of human beings, and debate the merits of more or less stringent regimes of regulation for biomedical innovation. In this article, these positions are shown to depend on a shared discourse of market liberalism, which limits both the range of ends for such innovation discussed by the authors, and the scope of their policy analyses and proposals. A proper evaluation of the human significance and policy imperatives for biomedical innovation needs to be both more utopian in its imagination, and more sophisticated in its political economy. In essence, the Fukuyama/Stock debate tells us more about current US political ideology than it does about the morality of human genetic and biopsychological engineering.

  9. Mimicry Is Presidential: Linguistic Style Matching in Presidential Debates and Improved Polling Numbers.

    Science.gov (United States)

    Romero, Daniel M; Swaab, Roderick I; Uzzi, Brian; Galinsky, Adam D

    2015-10-01

    The current research used the contexts of U.S. presidential debates and negotiations to examine whether matching the linguistic style of an opponent in a two-party exchange affects the reactions of third-party observers. Building off communication accommodation theory (CAT), interaction alignment theory (IAT), and processing fluency, we propose that language style matching (LSM) will improve subsequent third-party evaluations because matching an opponent's linguistic style reflects greater perspective taking and will make one's arguments easier to process. In contrast, research on status inferences predicts that LSM will negatively impact third-party evaluations because LSM implies followership. We conduct two studies to test these competing hypotheses. Study 1 analyzed transcripts of U.S. presidential debates between 1976 and 2012 and found that candidates who matched their opponent's linguistic style increased their standing in the polls. Study 2 demonstrated a causal relationship between LSM and third-party observer evaluations using negotiation transcripts.

  10. Gender equity in health: debates and dilemmas.

    Science.gov (United States)

    Doyal, L

    2000-09-01

    Gender equity is increasingly cited as a goal of health policy but there is considerable confusion about what this could mean either in theory or in practice. If policies for the promotion of gender equity are to be realisable their goal must be the equitable distribution of health related resources. This requires careful identification of the similarities and differences in the health needs of men and women. It also necessitates an analysis of the gendered obstacles that currently prevent men and women from realising their potential for health. This article explores the impact of gender divisions on the health and the health care of both women and men and draws out some of the policy implications of this analysis. It outlines a three point agenda for change. This includes policies to ensure universal access to reproductive health care, to reduce gender inequalities in access to resources and to relax the constraints of rigidly defined gender roles. The article concludes with a brief overview of the practical and political dilemmas that the implementation of such policies would impose.

    Benediktsson, Jon A.; Swain, Philip H.

    1992-01-01

    Consensus theory is adopted as a means of classifying geographic data from multiple sources. The foundations and usefulness of different consensus theoretic methods are discussed in conjunction with pattern recognition. Weight selections for different data sources are considered and modeling of non-Gaussian data is investigated. The application of consensus theory in pattern recognition is tested on two data sets: 1) multisource remote sensing and geographic data and 2) very-high-dimensional remote sensing data. The results obtained using consensus theoretic methods are found to compare favorably with those obtained using well-known pattern recognition methods. The consensus theoretic methods can be applied in cases where the Gaussian maximum likelihood method cannot. Also, the consensus theoretic methods are computationally less demanding than the Gaussian maximum likelihood method and provide a means for weighting data sources differently.

Since one cannot broach questions about the subject and its identity without analyzing their constitutive vectors, in this essay I explore how feminist theories have articulated alternative and more positive accounts of the subject and identity which, without abandoning the epistemological inevitability of the subject's de-construction, nonetheless resist the danger of emptying it of any materiality.

  17. Understanding the debate on medical education research: a sociological perspective.

    Science.gov (United States)

    Albert, Mathieu

    2004-10-01

    Since the mid-1990s, a debate has taken place among medical education scholars regarding the forms that research should take and the roles it should play. Editors of major journals in medical education and prominent researchers in the domain have repeatedly addressed the issue and have attempted to define what medical education research should be. The goal of this article is to look at the debate from a sociological perspective and to outline the social factors shaping it. An analysis of the texts published since 1990 addressing the issue shows that the debates can be deconstructed in four topics: epistemology, methodology, the primary purpose of medical education research, and the "quality" of the projects carried out in the domain. However, the debates can also be amalgamated and synthesized using the concept of "field" as developed by sociologist Pierre Bourdieu. A "field" refers to the configuration of power relations among individuals, social groups, or institutions within a domain of activities. Scientific fields are typically structured around a "bipolar" opposition pattern. At one pole stand those individuals who promote greater collaboration with nonscientists as well as research aimed at responding to practical needs. At the opposite pole stand those individuals who aspire to achieve independence of the field from such external constraints. The use of the concept of "field" allows us to understand the debate from a larger perspective and to establish parallels with similar debates in other scientific fields. In doing so, we will have the opportunity to learn from the experience of these other fields and be more reflective about the debate in which we engage.

    Possible mechanisms for overlimiting current (OLC) through aqueous ion-exchange membranes (exceeding diffusion limitation) have been debated for half a century. Flows consistent with electro-osmotic instability have recently been observed in microfluidic experiments, but the existing theory neglects chemical effects and remains to be quantitatively tested. Here, we show that charge regulation and water self-ionization can lead to OLC by “current-induced membrane discharge” (CIMD), even in the...

  1. Heteronormative consensus in the Norwegian same-sex adoption debate?

    Science.gov (United States)

    Anderssen, Norman; Hellesund, Tone

    2009-01-01

    This article investigates the Norwegian newspaper debate (1998-2002) on the right of homosexual couples to adopt children. It identifies two patterns of meaning within which both anti-adoption and pro-adoption sides of the debate were located: 1) the nuclear family as reference point; and 2) a focus on innate qualities. Parallell to a continuous liberalization of sexualities in Norway we seem to witness a consensus on heteronormativity in Norway on both sides of the debate as the basic axiom in public discussions on homosexuality and adoption. In this article, we explore the nature of the heteronormative arguments and the reason for their appearance in this particular debate. The two patterns of meaning reproduce a perception of lesbians and gays as either a worthy or unworthy minority. These findings may be seen as reflecting fundamental positions regarding the Norwegian modernization project, where both sides of the debate see homosexuality as a central symbol. State feminism may also have played the role of reinforcing gender categories and thereby served as an important condition of possibility for contemporary heteronormativity.

  2. The Basic Theoretical Framework

    Science.gov (United States)

    Loeb, Abraham

    Cosmology is by now a mature experimental science. We are privileged to live at a time when the story of genesis (how the Universe started and developed) can be critically explored by direct observations. Looking deep into the Universe through powerful telescopes, we can see images of the Universe when it was younger because of the finite time it takes light to travel to us from distant sources. Existing data sets include an image of the Universe when it was 0.4 million years old (in the form of the cosmic microwave background), as well as images of individual galaxies when the Universe was older than a billion years. But there is a serious challenge: in between these two epochs was a period when the Universe was dark, stars had not yet formed, and the cosmic microwave background no longer traced the distribution of matter. And this is precisely the most interesting period, when the primordial soup evolved into the rich zoo of objects we now see. The observers are moving ahead along several fronts. The first involves the construction of large infrared telescopes on the ground and in space, that will provide us with new photos of the first galaxies. Current plans include ground-based telescopes which are 24-42 m in diameter, and NASA's successor to the Hubble Space Telescope, called the James Webb Space Telescope. In addition, several observational groups around the globe are constructing radio arrays that will be capable of mapping the three-dimensional distribution of cosmic hydrogen in the infant Universe. These arrays are aiming to detect the long-wavelength (redshifted 21-cm) radio emission from hydrogen atoms.

  5. E-cigarettes: a need to broaden the debate.

    2016-11-01

    The unregulated market for e-cigarettes continues to grow, with debates on their efficacy and impact on global public health. E-cigarettes, or electronic nicotine delivery systems (ENDs), are marketed as a 'safe' alternative to tobacco products and a tool for 'harm reduction'. Some public health experts are calling it a 'game changer' and favour the 'harm reduction' strategy, while others dispute this claim. In our opinion, the debate needs to be broadened to encompass other related concerns and effects on non-users and affected stakeholders. As with tobacco control, a holistic approach is needed to build a raft of policies that effectively address the issue from all angles and look beyond the direct health implications of e-cigarette use to explore the social, economic, political and environmental aspects of this debate, putting 'harm reduction' in context.

  6. [The first Dutch debate on anaesthesia in obstetrics].

    2015-01-01

    After the publication of the Dutch medical guideline on pharmacological analgesia during childbirth in 2008, the question of whether pharmacological pain relief should be permissible during labour was hotly debated. This discussion has been going on since the second half of the 19th century when the introduction of ether and chloroform was extensively studied and described in Great Britain. This article looks back on the same debate in the Netherlands when inhalational anaesthetics were introduced into obstetrics. Study of historical journals and textbooks, originating in the Netherlands and elsewhere, and of historical medical literature on anaesthesia and obstetrics shows that the Dutch protagonists adopted more nuanced ideas on this issue than many of their foreign colleagues. This description of the first Dutch debate on anaesthesia in obstetrics shows that in fact the issues and arguments are timeless.

    Full Text Available The present paper illustrates the use of the brand and its components in the most important campaign debate of the presidential elections in Romania in 2009.The research method we have selected is the case study. The research technique consisted of the content analysis of the two speeches. The conducted analysis has included all the three types of the content analysis: conceptual, relational and qualitative analysis. The content analysis has been conducted by using the Nvivo software. The identification of the candidate’s brand in a single debate particularly entails its presence throughout the electoral campaign. We can outline the main component of the brand notion the two candidates have resorted to in this debate: Băsescu resorted to positioning, while Antonescu opted for differentiation and positioning.

  9. Debates about Conflict of Interest in Medicine: Deconstructing a Divided Discourse.

    2017-03-01

    The pharmaceutical industry plays an increasingly dominant role in healthcare, raising concerns about "conflicts of interest" (COI) on the part of the medical professionals who interact with the industry. However, there is considerable disagreement over the extent to which COI is a problem and how it should be managed. Participants in debates about COI have become entrenched in their views, which is both unproductive and deeply confusing for the majority of medical professionals trying to work in an increasingly commercialized environment. We used a modified meta-narrative review method to analyse debates about COI in the academic and grey literature. We found two Discourse Models: The Critical Discourse Model sees COI in health and biomedicine as a major problem that both can and should be addressed, while the Defensive Discourse Model argues that current efforts to control COIs are at best unnecessary and at worst harmful. Each model is underpinned by profoundly differing views about how society should be organized-in particular whether market forces should be encouraged or curtailed-and how the dangers associated with market forces should be managed. In order to make any headway, academics and policymakers must recognize that these debates are underpinned by profoundly differing worldviews.

  10. The pros and cons of human therapeutic cloning in the public debate.

    2002-09-11

    Few issues linked to genetic research have raised as much controversial debate as the use of somatic cell nuclear transfer technology to create embryos specifically for stem cell research. Whereas European countries unanimously agree that reproductive cloning should be prohibited there is no agreement to be found on whether or not research into therapeutic cloning should be permitted. Since the UK took the lead and voted in favour of regulations allowing therapeutic cloning the public debate has intensified on the Continent. This debate reflects the wide spectrum of diverse religious and secular moralities that are prevalent in modern multicultural European democratic societies. Arguments range from putting forward strictly utilitarian views that weight the moral issues involved against the potential benefits that embryonic stem cell research may harbour to considering the embryo as a human being, endowed with human dignity and human rights from the moment of its creation, concluding that its use for research is unethical and should be strictly prohibited. Given the current state of dissension among the various European states, it is difficult to predict whether 'non-harmonisation' will prevail or whether in the long run 'harmonisation' of legislation that will allow stem cell research will evolve in the EU.

  11. "Managed competition" for Ireland? The single versus multiple payer debate.

    LENUS (Irish Health Repository)

    2014-09-01

    A persistent feature of international health policy debate is whether a single-payer or multiple-payer system can offer superior performance. In Ireland, a major reform proposal is the introduction of \\'managed competition\\' based on the recent reforms in the Netherlands, which would replace many functions of Ireland\\'s public payer with a system of competing health insurers from 2016. This article debates whether Ireland meets the preconditions for effective managed competition, and whether the government should implement the reform according to its stated timeline. We support our arguments by discussing the functioning of the Dutch and Irish systems.

    Although there is a general consensus on African origin of early modern humans, there is disagreement about how and when they dispersed to Eurasia. This paper reviews genetic and Middle Stone Age/Middle Paleolithic archaeological literature from northeast Africa, Arabia, and the Levant to assess the timing and geographic backgrounds of Upper Pleistocene human colonization of Eurasia. At the center of the discussion lies the question of whether eastern Africa alone was the source of Upper Pleistocene human dispersals into Eurasia or were there other loci of human expansions outside of Africa? The reviewed literature hints at two modes of early modern human colonization of Eurasia in the Upper Pleistocene: (i) from multiple Homo sapiens source populations that had entered Arabia, South Asia, and the Levant prior to and soon after the onset of the Last Interglacial (MIS-5), (ii) from a rapid dispersal out of East Africa via the Southern Route (across the Red Sea basin), dating to ~74–60 kya.

    Full Text Available Studies on the passage from educational institutions to work and adult life have gained momentum in the framework of the employment crisis. Since the 1980s, changes in the situations that affect the life trajectories of contemporary youth have been a topic of discussion. This article addresses such issues by analyzing the educational and work careers of a group of young urban Argentines. The study focuses on a particular moment of their trajectories: that of the transition from high school graduation to higher education and/or work. In this way we attempt to reach a substantive discussion on those discretionary and/or determining factors that can be identified in the configuration of these transitions as well as on the points of tension that were encountered. The research is based on a reconstruction of the experiences of a group of youth (Cohort-2003 from different public and private high schools in townships in the cities of Buenos Aires and La Plata, Argentina, and involves the description given by these young people and their perception of the various scenarios that comprise their traveled paths.

    2015-09-01

    In the last years, the Danish debate about priority setting in medicine has gained new strength. This paper shows the main focuses of the current discussion based on a research of Danish primary literature. For the first time since the 1990s the Danish Council of Ethics has been involved with priority setting in medicine in a project running from 2011 to 2013. The Council emphasises the importance of legitimate processes and calls for visible values and criteria. A focus of the debate is how to deal with new expensive drugs. Politicians, physicians, health economists and the Council of Ethics have called for a national institution for priority setting in medicine. They have mainly looked to the Norwegian National Council for Priority Setting in Health Care and the British National Institute for Health and Care Excellence for inspiration. The Danish Government considered establishing a national institute for priority setting, but the plans were not put into practice. In the year 2012 a new national project was launched to create clinical guidelines. Danish doctors welcome the guidelines as a good basis for priority setting. Just like in earlier Danish priority setting debates, a coordinating institution is lacking to bundle the discussion and keep it going. The debate seems to have come to an end once again. The fact that it was seriously considered to establish an institute for priority setting is a new development. It can be expected that the discussion will be resumed in the near future, possibly the idea of an institute for priority setting will be readopted. The general conditions for priority setting in health care have improved.

    This award supported a broadly based research effort in theoretical particle physics, including research aimed at uncovering the laws of nature at short (subatomic) and long (cosmological) distances. These theoretical developments apply to experiments in laboratories such as CERN, the facility that operates the Large Hadron Collider outside Geneva, as well as to cosmological investigations done using telescopes and satellites. The results reported here apply to physics beyond the so-called Standard Model of particle physics; physics of high energy collisions such as those observed at the Large Hadron Collider; theoretical and mathematical tools and frameworks for describing the laws of nature at short distances; cosmology and astrophysics; and analytic and computational methods to solve theories of short distance physics. Some specific research accomplishments include + Theories of the electroweak interactions, the forces that give rise to many forms of radioactive decay; + Physics of the recently discovered Higgs boson. + Models and phenomenology of dark matter, the mysterious component of the universe, that has so far been detected only by its gravitational effects. + High energy particles in astrophysics and cosmology. + Algorithmic research and Computational methods for physics of and beyond the Standard Model. + Theory and applications of relativity and its possible limitations. + Topological effects in field theory and cosmology. + Conformally invariant systems and AdS/CFT. This award also supported significant training of students and postdoctoral fellows to lead the research effort in particle theory for the coming decades. These students and fellows worked closely with other members of the group as well as theoretical and experimental colleagues throughout the physics community. Many of the research projects funded by this grant arose in response to recently obtained experimental results in the areas of particle physics and cosmology. We describe a few of

  9. Why public moralities matter--the relevance of socioempirical premises for the ethical debate on organ markets.

    Science.gov (United States)

    Schweda, Mark; Schicktanz, Silke

    2014-06-01

    The ongoing bioethical debate about organ markets rests not only on theoretical premises, but also on assumptions regarding public views of and attitudes toward organ donation that need closer socioempirical examination. Summarizing results from our previous qualitative social research in this field, this paper illustrates the ethical significance of such public moralities in two respects: On one hand, it analyzes the implicit bias of the common rhetoric of "organ scarcity" which motivates much of the commercialization debate. On the other hand, it explores the blind spots of the paradigm of "altruistic donation" which informs many arguments against commercialization. We conclude that the ethical discourse has to appreciate the social nature of organ donation as a reciprocal interaction between different parties with irreducibly different but equally relevant viewpoints. We criticize the neglect of such well-founded public considerations in certain philosophical-ethical approaches and stress the need for further systematic and comparative socioempirical studies about peoples' actual perspectives in bioethics.

  10. The question of disability in the post-human debate. Critical remarks.

    Science.gov (United States)

    Gatti, Chiara

    2014-01-01

    The issue of disability represents a test case for the sustainability, practical and theoretical, of transhumanist theories that lead to the advent of a posthuman era. In fact, dealing with mankind implies also the possibility that man has a disability. So, seeing whether, in the posthuman debate, persons with disability are respected, will show us if every man is respected. In this paper we start by analyzing the definition of disability given by the posthuman theorists. As we will see, this definition is deficient because it is strictly linked with the transhumanists' refusal of the distinction between therapeutic treatment and enhancement. The field of enhancement is very wide, and the moral judgment on it cannot be generalized. Nowadays, many developments made possible by human enhancement theories remain only speculated upon. However, those theories are already influential in the field of studying the beginning of life. Indeed, the possibility "to choose children" is real: here the issue of disability is decisive and the risk of discrimination is very high. So, looking at the issue of disability will allow us to explore the ethical weight of the post-human project. In the background, it will be possible to glimpse the question of what is the essence of man, an issue not considered enough in the post-human debate. On the contrary, it is a fundamental question which should be answered before proceeding to a substantial alteration of humanity.

  18. UK parliamentary debate analysis: bombing ISIL in Syria.

    Science.gov (United States)

    Rashed, Haifa

    2016-01-01

    This paper examines the arguments presented for and against the UK government's motion for the UK to intervene militarily in Syria in the House of Commons debate on ISIL in Syria that took place on 2 December 2015. It considers what the most common arguments were in favour of and in opposition to the motion as well as which arguments were given the most emphasis, in order to understand the prime justifications given that led to the decision to approve the motion. It suggests that due to the shadow of the 2003 Iraq war, politicians in the debate placed a considerable emphasis on the legal justification for military intervention. It argues that the focus on the national security of the UK and its allies in this particular debate seems to contrast with previous military interventions where humanitarian motives were more widely stated. This paper calls for further comparative research of parliamentary debates in order to track such changes in the rhetoric used by UK politicians to defend their support for military intervention.

  19. The Boussinesq Debate: Reversibility, Instability, and Free Will.

    Science.gov (United States)

    Michael Mueller, Thomas

    2015-12-01

    In 1877, a young mathematician named Joseph Boussinesq presented a mémoire to the Académie des sciences which demonstrated that some differential equations may have more than one solution. Boussinesq linked this fact to indeterminism and to a possible solution to the free will versus determinism debate. Boussinesq's main interest was to reconcile his philosophical and religious views with science by showing that matter and motion do not suffice to explain all there is in the world. His argument received mixed criticism that addressed both his philosophical views and the scientific content of his work, pointing to the physical "realisticness" of multiple solutions. While Boussinesq proved to be able to face the philosophical criticism, the scientific objections became a serious problem, thus slowly moving the focus of the debate from the philosophical plane to the scientific one.
