Sample records for provoking public discussions

  1. Long timescales, low risks: rational containment objectives that account for ethics, resources, feasibility and public expectations some thoughts to provoke discussion

    International Nuclear Information System (INIS)

    Chapman, N.A.

    2002-01-01

    This paper discusses a range of technical and non-technical factors related to long timescales for deep geological repositories. It is intended to provoke discussion between implementers, regulators and the public about realistic containment and protection objectives for long-lived wastes such as spent fuel and HLW. The ethical and practical aspects of providing protection are discussed, along with society's perceptions of hazard, protection and time. A proposal is made for a series of time-graded containment levels that reflect objectively achievable and ethically reasonable protection for future generations. (authors)

    A massive open online course, or MOOC, is an noncredit education activity that delivers learning content to anyone with access to the Internet. Individual courses are generally free of charge, while a certificate can have small costs. The University of Wisconsin-Madison has exploring the use of MOOC as part of its Wisconsin Idea. In the 2015, a series of MOOCs focusing on the environment were offered via Coursera. One of those MOOCS was "Changing Weather and Climate of the Great Lakes Region." This 4-week course features a new season each week through short lectures and activities covering Great Lakes weather, observed changes in the climate, and societal impacts of climate change. (https://www.coursera.org/course/greatlakesclimate) The MOOC conveyed information from NOAA's National Weather Service (NWS) Weather-Ready Nation initiative as well as findings from the recent National Climate Assessment and the Wisconsin Initiative on Climate Change Impacts (WICCI). The course was organized by members of the Department of Atmospheric and Oceanic Sciences and the Cooperative Institute for Meteorological Satellite Studies; material included discussion, videos for lectures as well as guest lecturers. There were also weekly visits by the course team to 21 public libraries throughout the state of WI. The library collaboration as facilitated by WiLS (Wisconsin Library Services - wils.org), who organized the application and selection process. The public libraries hosted local residents and course instructors in discussions of course content in the context of their communities as well as strategies to mitigate the climate change impacts. This presentation will discuss the public library discussions experience and the our evaluation of the impact of including a face-to-face component in the MOOC activity on engagement and learning.

    We study the noncoherent capacity of secret-key agreement with public discussion over independent identically distributed (i.i.d.) Rayleigh fading wireless channels, where neither the sender nor the receivers have access to instantaneous channel state information (CSI). We present two results. At high signal-to-noise ratio (SNR), the secret-key capacity is bounded in SNR, regardless of the number of antennas at each terminal. Second, for a system with a single antenna at both the legitimate and the eavesdropper terminals and an arbitrary number of transmit antennas, the secret-key capacity-achieving input distribution is discrete, with a finite number of mass points. Numerically we observe that at low SNR, the capacity achieving distribution has two mass points with one of them at the origin. © 2011 IEEE.

    1982-01-01

    A group of adult patients with perennial bronchial asthma has been studied as to lung perfusion and alveolar ventilation (81m-Kr) at rest and after provocation of an acute attack. Asthma was provoked by exercise and by histamine inhalation. After provocation the peak expiratory flow values were reduced to less than 80% of the base line values. Perfusion was often deranged. Regional ventilation changed rapidly after provocation and not always in the same fashion after exercise and histamine. During attacks lung volume increased. The expansion decreased (in parallel with increased peak expiratory flow) after inhalator of a #betta#-2 agonist (terbutaline). 81m-Kr offers unique opportunities for studying acute regional changes in alveolar ventilation.

  6. Enhancing the discussion of alternatives in EIA using principle component analysis leads to improved public involvement

    International Nuclear Information System (INIS)

    Kamijo, Tetsuya; Huang, Guangwei

    2017-01-01

    The purpose of this study is to show the effectiveness of principle component analysis (PCA) as a method of alternatives analysis useful for improving the discussion of alternatives and public involvement. This study examined public consultations by applying quantitative text analysis (QTA) to the minutes of meetings and showed a positive correlation between the discussion of alternatives and the sense of public involvement. The discussion of alternatives may improve public involvement. A table of multiple criteria analysis for alternatives with detailed scores may exclude the public from involvement due to the general public's limited capacity to understand the mathematical algorithm and to process too much information. PCA allowed for the reduction of multiple criteria down to a small number of uncorrelated variables (principle components), a display of the merits and demerits of the alternatives, and potentially made the identification of preferable alternatives by the stakeholders easier. PCA is likely to enhance the discussion of alternatives and as a result, lead to improved public involvement.

    To discuss the actual public image of nurses and other factors that influence the development of nurses' self-concept and professional identity. Nurses have become healthcare professionals in their own right who possess a great deal of knowledge. However, the public does not always value the skills and competences nurses have acquired through education and innovation. Discussion paper. We identified 1216 relevant studies by searching MEDLINE, CINAHL and PsycINFO databases in the period 1997-2010. Finally, 18 studies met our inclusion criteria. The included studies show that the actual public image of nursing is diverse and incongruous. This image is partly self-created by nurses due to their invisibility and their lack of public discourse. Nurses derive their self-concept and professional identity from their public image, work environment, work values, education and traditional social and cultural values. Nurses should work harder to communicate their professionalism to the public. Social media like the Internet and YouTube can be used to show the public what they really do. To improve their public image and to obtain a stronger position in healthcare organizations, nurses need to increase their visibility. This could be realized by ongoing education and a challenging work environment that encourages nurses to stand up for themselves. Furthermore, nurses should make better use of strategic positions, such as case manager, nurse educator or clinical nurse specialist and use their professionalism to show the public what their work really entails. © 2013 John Wiley & Sons Ltd.

  8. Breastfeeding (Un)Covered: Narratives of Public Breastfeeding on Romanian Discussion Forums.

    Science.gov (United States)

    Tăut, Diana

    2017-12-01

    The aim of this study was to explore the construction of breastfeeding in public, as depicted in the stories and the opinions of women participating in discussions on public forums. There were 8 discussion forums selected, from which 769 messages were subjected to a narrative analysis further informed by recurrent themes identified in the literature and across messages. The emerging narratives were grouped based on their valence, and three broader categories of themes were formed, highlighting the predominant tone towards breastfeeding in public. The three broader themes, 'public restraint of breast(feeding) as acknowledgement of the cultural status-quo', 'permission within boundaries' and 'breast(feeding) as a human right', depict various meanings and experiences associated with public breastfeeding. People seeing breasts as mainly a cultural symbol of sexuality were more against public breastfeeding and more in favour of covering up or striving to discretion. Those arguing that breastfeeding is no more than exercising a fundamental right and pleading for breast as a primary maternal symbol were more in favour of breastfeeding in public. Aiming to understand personal and social perspectives on public breastfeeding is informative for understanding cultural differences in breastfeeding rates but also for designing effective interventions to promote it.

  9. Addressing public concerns about ethical and environmental issues in the discussion on nuclear waste management

    International Nuclear Information System (INIS)

    Luthi, A.

    1996-01-01

    According to Swiss Federal Law, the producers of radioactive waste are responsible for its safe disposal. The government, therefore, plays a relatively modest role in the public debate on nuclear waste management. Whenever asked to express an opinion, it tries to inform openly. Active public relations campaigns are led by the National Co-operative for the Disposal of Radioactive Waste (NAGRA). The operators of nuclear power plants are ready to compensate the siting community and its Canton for services rendered in the public interest. An important way to deal with ethical and environmental issues is the inclusion of opponents in every step of the time-consuming licensing procedure. This paper discusses the upcoming vote on a concession for a low and intermediate-level waste repository for which NAGRA is actively preparing. NAGRA's public relations work is based on recognition of the fact that the only way to diminish fear and gain credibility is to inform openly and regularly over many years, and to show that results achieved are based on serious, careful and transparent scientific work. Another aspect of radioactive waste management communication lies in the explanation of the ethics of 'inter-generational' and 'intra-generational' equity. Compensation will never make up for lack of safety. The ways in which the public voices its views are discussed, as well as the concept of seeking the co-operation of opponents in working groups.

    Patients' willingness to discuss costs of treatment alternatives with their physicians is uncertain. To explore public attitudes toward doctor-patient discussions of insurer and out-of-pocket costs and to examine whether several possible communication strategies might enhance patient receptivity to discussing costs with their physicians. Focus group discussions and pre-discussion and post-discussion questionnaires. Two hundred and eleven insured individuals with mean age of 48 years, 51 % female, 34 % African American, 27 % Latino, and 50 % with incomes below 300 % of the federal poverty threshold, participated in 22 focus groups in Santa Monica, CA and in the Washington, DC metro area. Attitudes toward discussing out-of-pocket and insurer costs with physicians, and towards physicians' role in controlling costs; receptivity toward recommended communication strategies regarding costs. Participants expressed more willingness to talk to doctors about personal costs than insurer costs. Older participants and sicker participants were more willing to talk to the doctor about all costs than younger and healthier participants (OR = 1.8, p = 0.004; OR = 1.6, p = 0.027 respectively). Participants who face cost-related barriers to accessing health care were in greater agreement than others that doctors should play a role in reducing out-of-pocket costs (OR = 2.4, p = 0.011). Participants did not endorse recommended communication strategies for discussing costs in the clinical encounter. In contrast, participants stated that trust in one's physician would enhance their willingness to discuss costs. Perceived impediments to discussing costs included rushed, impersonal visits, and clinicians who are insufficiently informed about costs. This study suggests that trusting relationships may be more conducive than any particular discussion strategy to facilitating doctor-patient discussions of health care costs.

  11. SaskEnergy small volume customers - direct gas purchase stakeholder discussion and public input report

    International Nuclear Information System (INIS)

    Davidson, M. A.

    1998-01-01

    With the approval of the Provincial Government of Saskatchewan, SaskEnergy, the provincial utility decided to extend the premise of natural gas deregulation to all sizes of customers by opening the core market for natural gas commodity sales to private sector natural gas agents, brokers and marketers (ABMs). SaskEnergy will continue to provide natural gas transportation and storage related services. Before doing so, the Utility sought to discuss with various stakeholders the terms and conditions that would need to be met by industry to enter into the Saskatchewan market. To assure a balanced interest during the discussions that would include a perspective on consumer protection requirements, the Utility contracted KPMG Regina to chair the stakeholders discussion table and facilitate a public input process for interested individuals to channel comments and seek responses to questions. This report contains the edited summary of the four meetings held by stakeholders. The stakeholders were successful in providing SaskEnergy with insight and suggestions to ensure that a direct purchase market will be developed in Saskatchewan, and that consumers will have objective information to make informed choices about their natural gas purchase options. The meetings also produced an ABMs Code of Conduct, a Direct Purchase 'Enrollment Agreement' and a 'Disclosure Agreement' and delivery terms and conditions for the core market that are similar to industry requirements in the rest of Canada. Copies of the draft forms are included in appendices to this summary report

    2016-01-01

    This paper considers the problem of secret-key agreement with public discussion subject to a peak power constraint A on the channel input. The optimal input distribution is proved to be discrete with finite support. To overcome the computationally heavy search for the optimal discrete distribution, several suboptimal schemes are proposed and shown numerically to perform close to the capacity. Moreover, lower and upper bounds for the secret-key capacity are provided and used to prove that the secret-key capacity converges for asymptotic high values of A, to the secret-key capacity with an average power constraint A2. Finally, when the amplitude constraint A is small (A ! 0), the secret-key capacity is proved to be asymptotically equal to the capacity of the legitimate user with an amplitude constraint A and no secrecy constraint.

    We study the Rayleigh fading non-coherent capacity of secret-key agreement with public discussion, where neither the sender nor the receivers have access to instantaneous channel state information (CSI) of any channel. We present two results. At high Signal-to-Noise Ratio (SNR), the secret-key capacity is bounded in SNR, regardless of the number of antennas at each terminal. Second, for a system with a single antenna at both the legitimate and the eavesdropper terminals and an arbitrary number of transmit antennas, the secret-key capacity-achieving input distribution is discrete, with a finite number of mass points. Numerically we observe that at low-SNR, the capacity achieving distribution has two mass points with one of them at the origin. © 2011 IEEE.

  17. Experience of the use of comparative evaluations of risks in the public discussion about nuclear energy

    International Nuclear Information System (INIS)

    Borsch, P.

    1983-01-01

    In the nuclear controversy the risks of nuclear facilities play a major role. An evaluation of these risks is possible only by comparison with other risks to which people are exposed. For this purpose the selection of suitable comparative risk sources is important. But even if appropriate risk sources have been chosen, there will always be some rest dimensions which are difficult to encompass into the comparison. Among these problems are: the maximum damage, the time frame, the practical experience with a risk source, the different composition of the risk (death, injuries, cancers etc.), the uncertainty of risk assessment results, especially for chronic and late effects. One has to pay attention to these obstacles of comparing risks in the public discussion. Experience shows that risk comparison will be easier accepted if one explicitly refers to this difficulty. Also the different components of risks have to be presented, at least from its basic concept. An interesting possibility is the comparison of different risks with regard to their shortening of life expectancy. This common delimiter has to be used with care, since some comparisons decrease the probability of public acceptance for this method. Nevertheless this method provides a good illustration, of how small e.g. the risk of low doses of ionizing radiation is in comparison to smoking cigarettes. In any case it has to be pointed out that risk is not the only criterion for decisions about a technology, but that other factors like economics, fuel supply, degree of technical development have to be taken into account

  20. Remarks presented (questions/answers discussed) at public regional meetings to discuss regulations (10 CFR Part 21) for reporting of defects and noncompliance, July 12--26, 1977

    International Nuclear Information System (INIS)

    1977-09-01

    In enacting the Energy Reorganization Act of 1974, Congress included Section 206 which requires the reporting of defects and noncompliances directly to the Nuclear Regulatory Commission (NRC). This congressional action required that the NRC promulgate rules and regulations, as necessary, to assure appropriate implementation of Section 206. In response to this mandate, the NRC drafted a new regulation. Following a period of public comment and revision, the regulation identified as 10 CFR Part 21, Reporting Defects and Noncompliance, was published in a Federal Register Notice on June 6, 1977. To assist NRC licensees and other firms and organizations covered by the new Part 21 regulation, public regional meetings were conducted by staff representatives to explain the rule. At these meetings the staff presented prepared remarks and answered questions on the meaning and application of the rule. Staff remarks contained in the original publication of this document were also provided to those in attendance. At each meeting the staff received a request for the questions and answers discussed by the staff to be made available for use as guidance by the nuclear industry covered by the rule. It was announced that a consolidation of the staff position question/answer guidance would be made available to each organization or firm attending these meetings and for others where a request is made in accordance with the directions printed insidethe front cover of the document. The staff will be guided in its implementation and enforcement of Part 21 by the positions set forth in the document. The revision of NUREG-0302 includes the following three parts relating to 10 CFR Part 21: (1) remarks presented by staff representatives; (2) Federal Register Notice material; and (3) a consolidation of questions and answers from the public regional meetings

    In an effort to identify previously unrecognized aspects of editorial decision-making, we explored the words and phrases that one group of editors used during their meetings. We performed an observational study of discussions at manuscript meetings at JAMA, a major US general medical journal. One of us (KD) attended 12 editorial meetings in 2003 as a visitor and took notes recording phrases from discussion surrounding 102 manuscripts. In addition, editors attending the meetings completed a form for each manuscript considered, listing the reasons they were inclined to proceed to the next step in publication and reasons they were not (DR attended 4/12 meetings). We entered the spoken and written phrases into NVivo 2.0. We then developed a schema for classifying the editors' phrases, using an iterative approach. Our classification schema has three main themes: science, journalism, and writing. We considered 2,463 phrases, of which 87 related mainly to the manuscript topic and were not classified (total 2,376 classified). Phrases related to science predominated (1,274 or 54%). The editors, most of whom were physicians, also placed major weight on goals important to JAMA's mission (journalism goals) such as importance to medicine, strategic emphasis for the journal, interest to the readership, and results (729 or 31% of phrases). About 16% (n = 373) of the phrases used related to writing issues, such as clarity and responses to the referees' comments. Classification of editorial discourse provides insight into editorial decision making and concepts that need exploration in future studies.

  10. Discussing Climate Change with the Public: Presenting the Science is Necessary but Insufficient

    Science.gov (United States)

    Vincelli, P.; Humble, J.

    2012-12-01

    Social science literature shows that the topic of climate change is imbued with cultural meaning for most Americans, such that sound scientific information alone is likely to be unpersuasive to people already doubtful about climate change. A current educational program on climate change emphasizes the following: *Less reliance on geophysical data *Positive messages as frequently as possible *Making the subject personal and concrete *Focusing on scientific aspects of climate change while refraining from promotion of particular policy solutions *Seeking ways to speak to core identities of diverse audiences *Assuring that communication efforts on this highly divisive topic are based on sensitivity to, and respect for, the diversity of worldviews present in citizens *To the extent possible, emphasizing optimism as well as our personal and collective capability to solve the problem of climate change. While this may seem self-evident, we also remind ourselves of the importance of avoiding criticism, blame, demonization, or arrogance in building a more inclusive community of public leaders on climate literacy.; Citing the recognition of climate-change science by trusted organizations is probably more convincing than showing reams of geophysical data. In particular, citing the Department of Defense may speak to the values of many who remain skeptical. ; This image is intended to speak to people that deeply value passing on a way of life to their descendants. Although nationalism can be carried to an extreme, this imagery can convey the notion that protecting our world from climate change is actually patriotic, something few Americans may realize.

    2016-01-01

    Social media can act as an important platform for debating, discussing, and disseminating information about vaccines. Our objectives were to map and describe the roles played by web-based mainstream media and social media as platforms for vaccination-related public debates and discussions during the Polio crisis in Israel in 2013: where and how did the public debate and discuss the issue, and how can these debates and discussions be characterized? Polio-related coverage was collected from May 28 to October 31, 2013, from seven online Hebrew media platforms and the Facebook groups discussing the Polio vaccination were mapped and described. In addition, 2,289 items from the Facebook group "Parents talk about Polio vaccination" were analyzed for socio-demographic and thematic characteristics. The traditional media mainly echoed formal voices from the Ministry of Health. The comments on the Facebook vaccination opposition groups could be divided into four groups: comments with individualistic perceptions, comments that expressed concerns about the safety of the OPV, comments that expressed distrust in the Ministry of Health, and comments denying Polio as a disease. In the Facebook group "Parents talk about the Polio vaccination", an active group with various participants, 321 commentators submitted 2289 comments, with 64 % of the comments written by women. Most (92 %) people involved were parents. The comments were both personal (referring to specific situations) and general in nature (referring to symptoms or wide implications). A few (13 %) of the commentators were physicians ( n  = 44), who were responsible for 909 (40 %) of the items in the sample. Half the doctors and 6 % of the non-doctors wrote over 10 items each. This Facebook group formed a unique platform where unmediated debates and discussions between the public and medical experts took place. The comments on the social media, as well as the socio-demographic profiles of the commentators, suggest

  13. The Concept of a Single-sex Optional Discussion Session in Introductory Astronomy at a Publicly Funded University

    Shawl, S.

    1996-12-01

    The concept of single-sex education for science and mathematics has recently received renewed discussion in both the popular and professional literature. So important is the topic within higher education that the Duke Journal of Gender Law and Policy sponsored a symposium called "Gender & The Higher Education Classroom: Maximizing the Learning Environment" in February 1996 (http://www.duke.edu/ jrd4/djgcnf96.htm). The concept is especially controversial in publicly supported educational institutions. The idea of offering an optional discussion session limited to a single sex in a university-level introductory astronomy course at a State-supported school was considered through discussions with a number of faculty and administrators, and through a questionnaire aimed at determining student attitudes toward the concept. The results of the student questionnaire will be presented. (While the questionnaire results will be seen to be in favor of such an optional discussion session, such sessions have not been offered.)

    Full Text Available Introduction. Acute generalized exanthematous pustulosis (AGEP is a skin disease characterized by the sudden appearance of generalized pustules, accompanied by elevated body temperature and neutrophilia. Objective. Presentation of a patient with AGEP provoked by furosemide. Case report. We present a case of a 65-year-old patient diagnosed with and treated for generalized pustular eruption, with fever and changes in laboratory tests. Numerous coexisting medical conditions and a great number of frequently changed drugs (ciprofloxacin, allopurinol, folic acid, calcium carbonate, cyclophosphamide, atorvastatin, betaxolol and furosemide hindered identification of the causative factor. Conclusions. On the basis of the medical history and clinical picture, the patient was diagnosed with generalized exanthematous pustulosis induced by furosemide.

    Marušić, Ana; Malički, Mario; von Elm, Erik

    2014-01-01

    Despite the fact that there are more than twenty thousand biomedical journals in the world, research into the work of editors and publication process in biomedical and health care journals is rare. In December 2012, the Esteve Foundation, a non-profit scientific institution that fosters progress in pharmacotherapy by means of scientific communication and discussion organized a discussion group of 7 editors and/or experts in peer review biomedical publishing. They presented findings of past editorial research, discussed the lack of competitive funding schemes and specialized journals for dissemination of editorial research, and reported on the great diversity of misconduct and conflict of interest policies, as well as adherence to reporting guidelines. Furthermore, they reported on the reluctance of editors to investigate allegations of misconduct or increase the level of data sharing in health research. In the end, they concluded that if editors are to remain gatekeepers of scientific knowledge they should reaffirm their focus on the integrity of the scientific record and completeness of the data they publish. Additionally, more research should be undertaken to understand why many journals are not adhering to editorial standards, and what obstacles editors face when engaging in editorial research.

  16. Contested embryonic culture in Japan--public discussion, and human embryonic stem cell research in an aging welfare society.

    Science.gov (United States)

    Sleeboom-Faulkner, Margaret

    2010-01-01

    This article explores the reasons for the lack of a broad discussion on bioethical regulation of human embryonic stem cell research (hESR) in Japan and asks why scientists experience difficulties accessing resources for hESR despite the acclaimed indifference of dominant Japanese culture to embryo research. The article shows how various social actors express their views on the embryo and oocyte donation in terms of dominant Japanese culture, foiled against what is regarded as Western culture. Second, it shows how the lack of concern with hESR should be understood in the context of public health policies and communications and bioethics decision making in Japan. Finally, it interprets the meaning of the embryo in the context of Japan as an aging modern welfare society, explaining how policymakers have come to emphasize the urgency of infertility problems over issues around abortion and embryonic life.

    2015-03-01

    Full Text Available Russia's accession to the WTO remained one of the most talked economic events for a long time. Representatives of various interest groups (both supporters and opponents of joining the organization attended in the public debate on this issue. The paper presents the results of the analysis of publications in the print media on Russia's accession to the WTO over a period from December 2010 to December 2013. The focuses of our attention are two time slots: one and a half years prior to the entry and one and a half years after. The total number of analyzed articles is 397. As a result of the research we made some conclusions about the features of the construction of the WTO's media image. The paper presents an analysis of the positions of representatives of different groups and an evaluation of their involvement in the discussion. In addition, we provide illustrations of basic strategies used for deproblematization of the Russia's accession to the WTO, as well as to make assumptions about the reasons for which such actions became necessary.

  18. Future Public Policy and Ethical Issues Facing the Agricultural and Microbial Genomics Sectors of the Biotechnology Industry: A Roundtable Discussion

    Diane E. Hoffmann

    2003-09-12

    On September 12, 2003, the University of Maryland School of Law's Intellectual Property and Law & Health Care Programs jointly sponsored and convened a roundtable discussion on the future public policy and ethical issues that will likely face the agricultural and microbial genomics sectors of the biotechnology industry. As this industry has developed over the last two decades, societal concerns have moved from what were often local issues, e.g., the safety of laboratories where scientists conducted recombinant DNA research on transgenic microbes, animals and crops, to more global issues. These newer issues include intellectual property, international trade, risks of genetically engineered foods and microbes, bioterrorism, and marketing and labeling of new products sold worldwide. The fast paced nature of the biotechnology industry and its new developments often mean that legislators, regulators and society, in general, must play ''catch up'' in their efforts to understand the issues, the risks, and even the benefits, that may result from the industry's new ways of conducting research, new products, and novel methods of product marketing and distribution. The goal of the roundtable was to develop a short list of the most significant public policy and ethical issues that will emerge as a result of advances in these sectors of the biotechnology industry over the next five to six years. More concretely, by ''most significant'' the conveners meant the types of issues that would come to the attention of members of Congress or state legislators during this time frame and for which they would be better prepared if they had well researched and timely background information. A concomitant goal was to provide a set of focused issues for academic debate and scholarship so that policy makers, industry leaders and regulators would have the intellectual resources they need to better understand the issues and concerns at stake.

    2015-06-14

    We consider secret-key agreement with public discussion over multiple-input multiple-output (MIMO) Rayleigh fast-fading channels under correlated environment. We assume that transmit, legitimate receiver and eavesdropper antennas are correlated. The legitimate receiver and the eavesdropper are assumed to have perfect channel knowledge while the transmitter has only knowledge of the correlation matrices. First, we derive the expression of the secret-key capacity under the considered setup. Then, we prove that the optimal transmit strategy achieving the secret-key capacity consists in transmitting independent Gaussian signals along the eingenvectors of the transmit correlation matrix. The powers allocated to each channel mode are determined as the solution to a numerical optimization problem that we derive. A necessary and sufficient condition for beamforming (i.e., transmitting along the strongest channel mode) to be capacity-achieving is derived. Finally, we analyze the impact of correlation matrices on the system performance and provide closed-form expressions of the gain/loss due to correlation in the high power regime.

A necessary and sufficient condition for beamforming (i.e., transmitting along the strongest channel mode) to be capacity-achieving is derived. Moreover, we analyze the impact of correlation matrices on the system performance. Finally, we study the system’s performance in the two extreme power regimes. In the high-power regime, we provide closed-form expressions of the gain/loss due to correlation. In the low signal-to-noise ratio (SNR) regime, we investigate the energy efficiency of the system by determining the minimum energy required for sharing a secret-key bit and the wideband slope while highlighting the impact of correlation matrices.

    Researchers have iterated that the future of synthetic biology and biotechnology lies in novel consumer applications of crossing biology with engineering. However, if the new biology's future is to be sustainable, early and serious efforts must be made towards social sustainability. Therefore, the crux of new applications of synthetic biology and biotechnology is public understanding and acceptance. The RASVaccine is a novel recombinant design not found in nature that re-engineers a common bacteria ( Salmonella ) to produce a strong immune response in humans. Synthesis of the RASVaccine has the potential to improve public health as an inexpensive, non-injectable product. But how can scientists move forward to create a dialogue of creating a 'common sense' of this new technology in order to promote social sustainability? This paper delves into public issues raised around these novel technologies and uses the RASVaccine as an example of meeting the public with a common sense of its possibilities and limitations.

  8. Medical humanities in nursing: thought provoking?

    Science.gov (United States)

    Robb, A J; Murray, R

    1992-10-01

    Medical humanities is an innovative way of learning. Discussing literary texts of nursing practice has been used to help students analyse attitudes, values and ethics; it has also been used to help practitioners review and reflect on their own experience and philosophy of nursing. In nursing education, it has been used to explore difficult issues in a safe environment. The value of this approach in nursing education and practice is that it can encourage reflection, promote self-awareness and stimulate debate on difficult issues: for example, death and dying, power and institutionalization (of patients and staff) and pain. This paper gives a detailed worked example of how a literary text can be used in this way, the aim being to provide a resource which readers can then use with a group of students or colleagues. Finally, the authors explore the question of where medical humanities might have a place in the curriculum: as a lecture/tutorial in a course (e.g. Ethics), as a module in the curriculum, as a method of teaching nursing subjects (e.g. communication skills), as a discussion group (outside the curriculum), as a study guide, using literary texts alongside nursing text books. Any of these strategies can be a powerful vehicle for preserving the 'human factor' in both nursing education and continuing professional development.

We herein report a 49-year-old male patient experiencing a life- threatening thyroid storm provoked by interleukin-2 (IL-2. This was a case of pulmonary metastasis of melanoma without a previous history of thyroid dysfunction. For the metastatic melanoma, he underwent combined immunochemotherapy including dacarbazine and IL-2. The 3rd course of immunochemotherapy was complicated with a thyroid storm manifested by high fever, tachycardia and even transient cardiac arrest. Fortunately, he recovered eventually from this crisis by immediate resuscitation followed by antithyroid dugs. Our case highlights the rare complication of a thyroid storm provoked by IL-2 treatment. Precaution against autoimmune thyroid dysfunction is required during treatment with IL-2 and probably also other kinds of newly-developed immunotherapy to avoid life-threatening complications.

Here, the two paradigms are compared, using evaluations of metabolic stability based on either microsomal clearance assay data or from the predicted in vivo hepatic clearance and half-life calculated through the combination of the venous well-stirred model and Øie-Tozer's model. The need for a shift in paradigm is presented, and its implications discussed. It is suggested that discussions about ADME data should revolve around potential clinical problems that are most likely to surface during the development phase, each benchmarked with a suitable variable derived from the assay data.

    If Public Health is the science and art of how society collectively aims to improve health, and reduce inequalities in health, then Public Health Economics is the science and art of supporting decision making as to how society can use its available resources to best meet these objectives and minimise opportunity cost. A systematic review of published guidance for the economic evaluation of public health interventions within this broad public policy paradigm was conducted. Electronic databases and organisation websites were searched using a 22 year time horizon (1990-2012). References of papers were hand searched for additional papers for inclusion. Government reports or peer-reviewed published papers were included if they; referred to the methods of economic evaluation of public health interventions, identified key challenges of conducting economic evaluations of public health interventions or made recommendations for conducting economic evaluations of public health interventions. Guidance was divided into three categories UK guidance, international guidance and observations or guidance provided by individual commentators in the field of public health economics. An assessment of the theoretical frameworks underpinning the guidance was made and served as a rationale for categorising the papers. We identified 5 international guidance documents, 7 UK guidance documents and 4 documents by individual commentators. The papers reviewed identify the main methodological challenges that face analysts when conducting such evaluations. There is a consensus within the guidance that wider social and environmental costs and benefits should be looked at due to the complex nature of public health. This was reflected in the theoretical underpinning as the majority of guidance was categorised as extra-welfarist. In this novel review we argue that health economics may have come full circle from its roots in broad public policy economics. We may find it useful to think in this broader

    Taking the three examples of nuclear energy, microelectronics and genetic engineering, an analytic perspective is proposed which goes beyond conventional technology assessment. A comparative approach to the analysis of these three consecutive developments is suggested focusing on their physical and social substitutional functions, relevant actor games and control mechanisms, and cultural assimilation. Finally, the issue of 'autonomy' or 'Eigendynamik' of modern science and technology is discussed. (orig.) [de

    The volume and velocity of data are growing rapidly and big data analytics are being applied to these data in many fields. Population and public health researchers may be unfamiliar with the terminology and statistical methods used in big data. This creates a barrier to the application of big data analytics. The purpose of this glossary is to define terms used in big data and big data analytics and to contextualise these terms. We define the five Vs of big data and provide definitions and distinctions for data mining, machine learning and deep learning, among other terms. We provide key distinctions between big data and statistical analysis methods applied to big data. We contextualise the glossary by providing examples where big data analysis methods have been applied to population and public health research problems and provide brief guidance on how to learn big data analysis methods. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

    Nutritional counseling for gastroparesis focuses on reduction of meal size, fiber, and fat to control symptoms. The tolerance of gastroparesis patients for particular foods is largely anecdotal. The aim of this study was to identify and characterize foods provoking or alleviating gastroparesis symptoms. Gastroparesis patients completed: (1) Demographic Questionnaire; (2) Patient Assessment of Upper GI Symptoms; (3) Food Toleration and Aversion survey asking patients about experiences when eating certain foods utilizing a scale from -3 (greatly worsening symptoms) to +3 (greatly improving symptoms). Descriptive qualities (acidic, fatty, spicy, roughage-based, bitter, salty, bland, and sweet) were assigned to foods. Forty-five gastroparesis patients participated (39 idiopathic gastroparesis). Foods worsening symptoms included: orange juice, fried chicken, cabbage, oranges, sausage, pizza, peppers, onions, tomato juice, lettuce, coffee, salsa, broccoli, bacon, and roast beef. Saltine crackers, jello, and graham crackers moderately improved symptoms. Twelve additional foods were tolerated by patients (not provoking symptoms): ginger ale, gluten-free foods, tea, sweet potatoes, pretzels, white fish, clear soup, salmon, potatoes, white rice, popsicles, and applesauce. Foods provoking symptoms were generally fatty, acidic, spicy, and roughage-based. The foods shown to be tolerable were generally bland, sweet, salty, and starchy. This study identified specific foods that worsen as well as foods that may help alleviate symptoms of gastroparesis. Foods that provoked symptoms differed in quality from foods that alleviated symptoms or were tolerable. The results of this study illustrate specific examples of foods that aggravate or improve symptoms and provide suggestions for a gastroparesis diet.

    Narcissism has long been used to predict aggressive or vengeful responses to provocations from others. The strength of this relation can, however, vary widely from study to study. Narcissism and revenge were examined in 84 independent samples (N = 11297), along with the moderating role of sample type (i.e., child/adolescent, prisoner, undergraduate, or general samples), type of narcissism measure used (i.e., Narcissistic Personality Inventory, Psychological Entitlement Scale, Short D3, etc.), the nature of the provocation, and the type of provoked aggression examined. Narcissism was positively related to provoked aggression across studies (ρ = .25), but that relation was stronger in child/adolescent samples (ρ = .36) and when measures of entitlement or vulnerable narcissism were employed (ρ = .29). Implications for practical research, as well as neglected areas of research on narcissism and provoked aggression are discussed. Aggr.

On one hand, the protection of nuclear weapons and materials continues as an urgent national security concern for both the United States and Russia. At the same time, defense infrastructures have been closed or converted to civilian purposes, and there has been increased activity in international cooperation for civilian nuclear technology. This special panel will explore the future of the U.S.-Russia nuclear cooperation with particular attention to the following three themes. Theme 1: Managing the Risks: U.S.-Russian Federation Cooperative Programs for Nuclear Weapons and Materials Security; Theme 2: Creating the Benefits: The Changing Nature of Russia's Domestic Nuclear Industry; Theme 3: Addressing the Impediments: United States and Russia as Nuclear Exporters: Reconciling Nonproliferation Goals, Technology Advancements, and Economic Incentives

    The Broad Public Djiscussion on Energy Policy (BMD) in the Netherlands is subdivided in an informative and a discussion stage. This intermediate report gives a summary of the first stage. In Ch. 2 the concept of energy and the utilized unities are discussed. Ch. 3 gives information about the actual energy consumption in the world and in the Netherlands and about the varying estimations for the future energy consumption. In Ch. 4 various possibilities for economization of energy in the Netherlands are discussed. Ch. 5 to 7 give the necessary information about the various energy sources. By source respectively the storages, applications, costs, effects on men and environment and public consequences are under discussion. Ch. 8 presents a comparative summary of the advantages and the drawbacks of various energy sources, the estimations for the future use and possibilities for energy economization. Also some attention is paid to the question on which grounds a choice from the policy possibilities may be based. Ch. 9 and 10 deal with the actual energy policy: how it is realized and what it holds. In Ch. 11 the results are discussed of four scenario-studies: how does the future energy consumption look like under different economical circumstances. What could be the effects of this on the environment at different applications of coal, natural gas, nuclear energy etc.. Furthermore the alternatives, which anounce themselves on the ground of the scenario studies, for the future energy policy are discussed. Finally the discussion questions are presented which following the coordination group will be the centre of interest in the second stage of the BMD. 427 refs.; figs.; tabs.

    of national studies that deal with the subject. There were selected articles that discuss accrual basis in the public sector from 2005 to 2012 published in periodicals and events punctuated by Capes related to accounting and/or public sector accounting. The results indicate that there is no stablished trend lines of research and the findings of one study does not tend to be compared with others. The searches have not been carried out forward, nor by other authors, or by themselves, and the authors have not exploited gaps left by previous searches, whether they are domestic or foreign. Comparisons between studies have also been affected, in some cases, due to methodological weaknesses. Thus, the Academy contributions to the understanding of the accrual basis applied to the public sector are rather fragmented, which can make it slow the progress in the subject.

    Among the many "firsts" of the Juno mission is the open enlistment of the public in the operation of its visible camera, JunoCam. Although the scientific thrust of the Juno mission is largely focused on innovative approaches to understanding the structure and composition of Jupiter's interior, JunoCam was added to the payload largely to function in the role of education and public outreach (E/PO). For the first time, the public was able to engage in the discussion and choice of targets for a major NASA mission. The discussion about which features to image is enabled by a continuously updated map of Jupiter's cloud system while Jupiter is far enough from the sun to be observable by non-professional astronomers. Contributors range from very devoted astrophotographers to telescope and video 'hobbyists'. Juno therefore engages the world-wide amateur-astronomy community as a vast network of co-investigators, whose products stimulate conversation and global public awareness of Jupiter and Juno's investigative role. Contributed images also provide a temporal context to inform the Juno atmospheric investigation team of the state and evolution of the atmosphere. The contributed images are used to create s global map on a bi-weekly basis. These bi-weekly maps provide the focus for ongoing discussion about various planetary features over a long time frame. Approximately two weeks before Juno's closest approach to Jupiter on each orbit ("perijove" or PJ), starting in mid-November of 2016 in preparation for PJ3 on December 11, the atmospheric features that have been under discussion and available to JunoCam on that perijove were nominated for voting, and the public at large voted on where to point JunoCam's "elective" features. In addition, JunoCam provides the first close-up images of Jupiter's polar regions from a non-oblique viewpoint for the first time in over 40 years since the passage of Pioneer 11 over Jupiter's north pole. The Juno mission science team also provides

In the final analysis the point of all these suggestions is to unbundle supplies and make sure that more competition creates more efficiency. This contribution looks at the empirical aspects of the problem. Some public power supply companies in Germany were selected in order to identify and describe inefficiencies of public power supply in Germany. Part two briefly describes the situation on the sector of ``public power supply`` which the emphasis on the commitment of the public. Part three describes the basics of data envelopment analysis which is then used in part 4 in order to analyse power suppliers. A distinction is made between private and public industry analysis. Part 5 contains some conclusions.

    Thin solid films have been used in various devices and engineering systems such as rapid development of highly integrated electronic circuits, the use of surface coatings to protect structural materials in high temperature environments, and thin films are integral parts of many micro-electro-mechanical systems designed to serve as sensors, actuators. Among techniques of ultra-thin films deposition, the heteroepitaxial method becomes the most useful at nanoscale level to obtain performed materials in various applications areas. On the other hand, stresses that appeared during the elaboration of thin films could rise deformations and fractures in materials. The key solution to solve this problem at the nanoscale level is the nucleation of interface dislocations from free surfaces. By provoking edge dislocation dipoles we obtained a strain relaxation in thin films. Moreover, the dynamic of nucleation in edge dislocations from free lateral surfaces was also studied.

    Discussions on euthanasia ("Sterbehilfe") that took place in the German Democratic Republic (GDR) have remained widely unnoticed by the historical sciences. By referring to various publications dating from the 1950s until today, this paper presents the basic ideas of the debate on euthanasia in the GDR and compares them-partly synchronically, partly diachronically-with the situation in the Federal Republic of Germany (FRG). A special focus is placed on positions and terminology related to medical ethics at the end of life in the former two German states. The methodical approach of the paper allows a transparent analysis of the question of whether the GDR debates on euthanasia are significant and independent, and whether they are relevant to current ethical debates on end-of-life practices in Germany.

  19. Peak provoked craving: an alternative to smoking cue-reactivity.

    Science.gov (United States)

    Sayette, Michael A; Tiffany, Stephen T

    2013-06-01

    Smoking cue-exposure research has provided a powerful tool for examining cravings in the laboratory. A key attraction of this method is that tightly controlled experimental procedures can model craving experiences that are presumed to relate to addiction. Despite its appeal, key assumptions underlying the clinical relevance of smoking cue-reactivity studies have been questioned recently. For both conceptual and methodological reasons it may be difficult to tease apart cue-based and abstinence-based cravings. Moreover, conventional cue-reactivity procedures typically generate levels of craving with only minimal clinical relevance. We argue here that sometimes it is unfeasible-and in some instances conceptually misguided-to disentangle abstinence-based and cued components of cigarette cravings. In light of the challenges associated with cue-reactivity research, we offer an alternative approach to smoking cue-exposure experimental research focusing on peak provoked craving (PPC) states. The PPC approach uses nicotine-deprived smokers and focuses on urges during smoking cue-exposure without subtracting out urge ratings during control cue or baseline assessments. This design relies on two factors found in many cue-exposure studies-nicotine deprivation and exposure to explicit smoking cues-which, when combined, can create powerful craving states. The PPC approach retains key aspects of the cue-exposure method, and in many circumstances may be a viable design for studies examining robust laboratory-induced cravings. © 2012 The Authors, Addiction © 2012 Society for the Study of Addiction.

    Full Text Available Saúde Coletiva e Ciências Sociais e Humanas são campos reconhecidamente inseparáveis, o que se afirma por uma tradição de grupos e linhas de pesquisa em programas de pós-graduação em Saúde Coletiva. Várias dificuldades têm sido apontadas, entretanto, em inserir discussões sobre temas tradicionalmente estudados nas ciências sociais, como a violência, no campo da saúde, ao mesmo tempo em que tal discussão tem sido vista como crucial para o entendimento de determinações de condições de saúde e qualidade de vida das populações. O foco de discussão sobre esse fenômeno carece de aportes teóricos de outras disciplinas, como a Sociologia, cujas teorias sobre o crime e sobre o desvio da norma constituem importante marco no estudo das violências. Neste artigo, o autor examina as teorias clássicas da sociologia nesse âmbito, buscando contribuir para a ampliação da discussão no campo da Saúde Coletiva, particularmente no que concerne a uma base de pensamento sobre a promoção, a prevenção e a reabilitação de agravos, considerando-a, assim, numa perspectiva interdisciplinar e de abrangência intersetorial.Public Health and the Human and Social Sciences are inseparable fields of knowledge, as attested by a tradition of research groups and research lines located in Public Health post-graduate programs. Several difficulties have been pointed when discussions about various themes traditionally identified with the social sciences, as is the case of violence, are inserted in the health field. At the same time, such discussions are considered essential to the understanding of the determination of populations' health conditions and quality of life. The discussion focus regarding this phenomenon lacks theoretical contributions from other disciplines, such as Sociology, whose theories on crime and deviance constitute an important benchmark in the study of the various forms of violence. In this article, the author examines the

  5. REMARKS TO THE CURRENT DISCUSSION ABOUT BIOENERGY –BIOENERGY FOR THE PUBLIC AND/ OR FOR THE AGRICULTURAL OR RURAL AREAS ONLY ?

    Full Text Available An energy system that is based on the use of renewable energy resources must be service –oriented and should be able to cover the varying energy demands. Moreover it must be flexible and cost effective by using on optimal mix of predominantly renewable energy sources. Agriculture will play an important role in the future if an optimal mix between food/feed production and energy plant production could be found. The present examples in the world to gain agricultural land for energy plants on the expenses of forests is going into the wrong direction. The cost intensive investments at present performed in Europe for biofuel and bioenergy production will certainly influence prices for crops and biomass supply. In this paper, strategies are questioned and discussed if the goals of the EU-commission to replace substantial parts of the fossile energy demands by bioenergy supply is feasible and can be realistic. As an example for a national agricultural situation, Austria, as am member of the PBBA, has elaborated a study about the timely development how much of the arable land can be utilized in the period between 2005 and 2020 for various bioenergy sources .The results demonstrate that, at the maximum , agriculture can only supply about 22 % of the total arable land for additional bioenergy as biofuel and biogas without interfering the national self food/feed supply and the protection of the sensible environment and emission situation. Finally, recent University research studies are presented about new processes to achieve a better and more efficient use of cereal and maize straw for biogas production already performed in the present 358 local biogas plants in Austria.

  10. Lack of effect of laboratory-provoked anxiety on plasma homovanillic acid concentration in normal subjects.

    Zemishlany, Z; Davidson, M

    1996-08-15

    The present study was undertaken to investigate if acute anxiety can affect plasma concentrations of homovanillic acid (pHVA). Since elevated pHVA levels have been associated with severity of schizophrenic symptoms, the results of this study will help determine if the pHVA elevations are directly related to psychosis or if anxiety is also a contributory factor. Anxiety was provoked in 10 young normal subjects by a combined paradigm of mental arithmetic task and threat of electrical shock. A significant increase in self-ratings of anxiety, blood pressure, and plasma levels of norepinephrine, 3-methoxy-4-hydroxyphenylethyleneglycol and growth hormone indicated that the paradigm used was effective in provoking anxiety; however, anxiety did not affect pHVA concentrations. The results may support the notion that increased pHVA levels in severely ill schizophrenic patients are related to the schizophrenic pathophysiology rather than to anxiety.

    Graphical abstract: - Highlights: • Mutagenicities of anti-cancer drugs were tested using HPRT, γH2AX and comet assays. • TRAIL, doxorubicin and etoposide were more mutagenic than BH3- or Smac-mimetics. • Physiologically achievable levels of the BH3-mimetic ABT-737 were not mutagenic. • High concentrations of ABT-737 provoked mutations via an off-target mechanism. • Even very high concentrations of IAP antagonists were not mutagenic. - Abstract: Chemotherapy and radiotherapy can cause permanent damage to the genomes of surviving cells, provoking severe side effects such as second malignancies in some cancer survivors. Drugs that mimic the activity of death ligands, or antagonise pro-survival proteins of the Bcl-2 or IAP families have yielded encouraging results in animal experiments and early phase clinical trials. Because these agents directly engage apoptosis pathways, rather than damaging DNA to indirectly provoke tumour cell death, we reasoned that they may offer another important advantage over conventional therapies: minimisation or elimination of side effects such as second cancers that result from mutation of surviving normal cells. Disappointingly, however, we previously found that concentrations of death receptor agonists like TRAIL that would be present in vivo in clinical settings provoked DNA damage in surviving cells. In this study, we used cell line model systems to investigate the mutagenic capacity of drugs from two other classes of direct apoptosis-inducing agents: the BH3-mimetic ABT-737 and the IAP antagonists LCL161 and AT-406. Encouragingly, our data suggest that IAP antagonists possess negligible genotoxic activity. Doses of ABT-737 that were required to damage DNA stimulated Bax/Bak-independent signalling and exceeded concentrations detected in the plasma of animals treated with this drug. These findings provide hope that cancer patients treated by BH3-mimetics or IAP antagonists may avoid mutation-related illnesses that afflict

    Pathogenic bacteria secrete protein toxins that provoke apoptosis or necrosis of eukaryotic cells. Here, we developed a live-imaging method, based on incorporation of a DNA-intercalating dye into membrane-damaged host cells, to study the kinetics of primary bone marrow-derived macrophages (BMDMs) mortality induced by opportunistic pathogen Pseudomonas aeruginosa expressing either Type III Secretion System (T3SS) toxins or the pore-forming toxin, Exolysin (ExlA). We found that ExlA promotes the activation of Caspase-1 and maturation of interleukin-1β. BMDMs deficient for Caspase-1 and Caspase-11 were resistant to ExlA-induced death. Furthermore, by using KO BMDMs, we determined that the upstream NLRP3/ASC complex leads to the Caspase-1 activation. We also demonstrated that Pseudomonas putida and Pseudomonas protegens and the Drosophila pathogen Pseudomonas entomophila, which naturally express ExlA-like toxins, are cytotoxic toward macrophages and provoke the same type of pro-inflammatory death as does ExlA + P. aeruginosa. These results demonstrate that ExlA-like toxins of two-partner secretion systems from diverse Pseudomonas species activate the NLRP3 inflammasome and provoke inflammatory pyroptotic death of macrophages. © 2017 Society for Applied Microbiology and John Wiley & Sons Ltd.

  15. Oral regurgitation after reflux provoking meals: a possible cause of dental erosion?

    Bartlett, D W; Evans, D F; Smith, B G

    1997-02-01

    Certain foods and drinks such as alcohol, heavily spiced or fatty meals are known to provoke gastro-oesophageal reflux (GOR). This may give rise to symptoms of heartburn, epigastric pain and occasionally oral regurgitation of the gastric contents. Oral regurgitation of gastric juice is important in dentistry because of its association with dental erosion. This study measured oesophageal and oral reflux in 12 healthy subjects after a curry meal taken with alcohol 2 h before sleep. Each subject repeated the test with a bland non-reflux provoking control meal. GOR was measured by recording distal and proximal oesophageal pH on a dual channel, portable pH monitor. Oral pH was measured with a pH sensitive radio-telemetry capsule (RTC) held on the palate in a vacuum formed splint. Signals from the RTC were received by an aerial worn around the head. The pH change produced by GOR was estimated as the percentage time that pH (PTpH) was less than 4 in the distal oesophagus. Similarly, the PTpH was estimated reflux in only two subjects. In one of these subjects the bland meal provoked oral regurgitation with a PTpH < 5.5 of 13.5%. In the remaining subjects little oral regurgitation occurred.

    Just as the natural environment can be polluted, so too can public discourse. I'm Right and You're an Idiot: The Toxic State of Public Discourse and How to Clean it Up examines the sorry state of today's public square, showing how polluted, polarized conversations discourage people from taking action on critical issues such as climate change, and demonstrating how we can clear the air and become more powerful and effective communicators. The most urgent environmental threat today is not climate change, species extinction or the declining health of oceans. Author Jim Hoggan says the more pressing problem is resistance to change that results from pollution in the public square. A smog of adversarial rhetoric, propaganda and polarization that comes from all sides, is stifling discussion and our ability to solve problems collectively. Hoggan has investigated this troubling state of public dialogue and in his new book he asks leading intellectuals why, despite overwhelming scientific evidence, so little is being done to address today's critical environmental challenges. As chair of the David Suzuki Foundation and founder of one of Canada's most successful PR firms, he is uniquely positioned to probe this question. During Hoggan's 30 years in crisis management he has dealt with food poisonings, labour disputes, multi-million dollar bank fraud, sawmill explosions, even bodies disappearing from funeral homes. He also authored the bestseller Climate Cover-Up, which took a critical look at science propaganda and the widespread echo chamber of media and think tanks that magnifies it. How do we improve public discourse and curb over-the-top advocacy, corrupt conversations and propaganda. How do we counteract polarization and gridlock? Hoggan sought answers from more than 60 outstanding scholars, ranging from a NASA scientist to deep-sea oceanographer. He tapped the brains of cognitive researchers, political pundits, philosophers, moral psychologists, corporate analysts and

    The aim of the present study was to evaluate the utility of different tests performed in the absence or presence of factors promoting seizures in order to evaluate the pro-convulsant effects of drugs. We studied the effects of theophylline in the rat since this is a well-known pro-convulsant substance in humans. The occurrence of spontaneous convulsions following administration of theophylline was evaluated by observation in the Irwin Test and by measuring brain activity using video-EEG recording in conscious telemetered animals. Theophylline was also tested in the electroconvulsive shock (ECS) threshold and pentylenetetrazole (PTZ)-induced convulsions tests, two commonly used models of provoked convulsions. In the Irwin test, theophylline induced convulsions in 1 out of 6 rats at 128 mg/kg. Paroxysmal/seizure activity was also observed by video-EEG recording in 4 out of the 12 animals tested at 128 mg/kg, in presence of clonic convulsions in 3 out of the 4 rats. Paroxysmal activity was observed in two rats in the absence of clear behavioral symptoms, indicating that some precursor signs can be detected using video-EEG. Clear pro-convulsant activity was shown over the dose-range 32-128 mg/kg in the ECS threshold and PTZ-induced convulsions tests. Evaluation of spontaneous convulsions provides information on the therapeutic window of a drug and the translational value of the approach is increased by the use of video-EEG. Tests based on provoked convulsions further complement the evaluation since they try to mimic high risk situations. Measurement of both spontaneous and provoked convulsions improves the evaluation of the pro-convulsant risk of novel pharmacological substances. Copyright © 2014 Elsevier Inc. All rights reserved.

    Television (TV) and video games (VG) can provoke seizures in patients with photosensitive epilepsies. Flicker frequency is the most important factor in screen activation. We tested conventional 50-Hz versus 100-Hz monitors during TV viewing and VG playing in 30 photosensitive subjects, 23 of whom had a history of TV or VG seizures or both. Fifteen subjects' discharges were activated by 50-Hz TV; 17 by 50-Hz VG; and one by a 100-Hz screen. Thus, 100-Hz screens protect against screen activation.

  2. Discussion in Postsecondary Classrooms

    2013-11-01

    Full Text Available Spoken language is, arguably, the primary means by which teachers teach and students learn. Much of the literature on language in classrooms has focused on discussion that is seen as both a method of instruction and a curricular outcome. While much of the research on discussion has focused on K-12 classrooms, there is also a body of research examining the efficacy of discussion in postsecondary settings. This article provides a review of this literature in order to consider the effect of discussion on student learning in college and university classrooms, the prevalence of discussion in postsecondary settings, and the quality of discussion in these settings. In general, the results of research on the efficacy of discussion in postsecondary settings are mixed. More seriously, researchers have not been explicit about the meaning of discussion and much of what is called discussion in this body of research is merely recitation with minimal levels of student participation. Although the research on discussion in college and university classrooms is inconclusive, some implications can be drawn from this review of the research including the need for future researchers to clearly define what they mean by “discussion.”

    The emotional evaluation of the causes of vertigo is made using the clinical records and several subjective questionnaires. The aim of the present study is to evaluate the emotional response objectively, in normal subjects, during an induced vertigo crisis. A caloric vestibular test with cold water was performed on 30 healthy subjects. The following physiological parameters were monitored during the 60seconds prior to and the 60seconds after the stimulation: Skin Conductivity, Peripheral Pulse Volume, Body Temperature, Muscle Contraction, Heart Rate, and Respiratory Rate. The maximum angular speed of the nystagmus slow phase at each stimulation was assessed. Skin conductance presented a statistically significant increase during the vertigo crisis in relation to the prior period while the peripheral pulse volume presented a statistically significant decrease. There was no relationship between the slow phase of the provoked nystagmus angular speed and skin conductance and peripheral pulse volume changes. The decrease in peripheral pulse volume was significantly higher in the second vertigo crisis. Skin conductance and peripheral pulse volume changed significantly during a vertigo crisis. There was no relation between the provoked vertiginous crisis intensity and the changes produced in those variables. The stress generated by the caloric stimulation is higher in the second crisis, when the subject has experience of the vertigo caused by the stimulation.

    Runaway currents following disruptions have an important effect on the first wall for the next generation tokamak. The behaviors of runaway currents following intentional provoked disruptions have been investigated in the J-TEXT tokamak. It is found that the runaway current generation following provoked disruptions depends on both the toroidal magnetic field and the plasma current. The conversion efficiency of pre-disruptive plasma currents into runaway currents is in the ranges of 30% to 60% in J-TEXT. The runaway currents can be avoided by the intensive gas puffing of H{sub 2} due to the low multiplication factor in J-TEXT. -- Highlights: ► The regime of runaway generation in disruptions in J-TEXT has been established. ► The magnetic field threshold for runaway current generation in disruptions is 2.2 T. ► The conversion efficiency of runaway current is in the ranges of 30% to 60%. ► The runaway currents can be avoided by the intensive gas puffing of H{sub 2}.

    Lipopolysaccharides (LPS) of gram-negative bacteria prime rabbit lungs for enhanced thromboxane-mediated vasoconstriction upon subsequent challenge with the exotoxin Escherichia coli hemolysin (HlyA) (Walmrath et al. J. Exp. Med. 1994;180:1437-1443). We investigated the impact of endotoxin priming and subsequent HlyA challenge on lung vascular permeability while maintaining constancy of capillary pressure. Rabbit lungs were perfused in a pressure-controlled mode in the presence of the thromboxane receptor antagonist BM 13.505, with continuous monitoring of flow. Perfusion for 180 min with 10 ng/ml LPS did not provoke vasoconstriction or alteration of capillary filtration coefficient (Kfc) values. HlyA (0.021 hemolytic units/ml) induced thromboxane release and a transient decrease in perfusion flow in the absence of significant changes in Kfc. Similar results were obtained when LPS and HlyA were coapplied simultaneously. However, when the HlyA challenge was undertaken after 180 min of LPS priming, a manifold increase in Kfc values was noted, with concomitant severe lung edema formation, although capillary pressure remained unchanged. Thus, endotoxin primes the lung vasculature to respond with a severe increase in vascular permeability to a subsequent low-dose application of HlyA. Such synergism between endotoxin priming and exotoxin challenge in provoking lung vascular leakage may contribute to the pathogenesis of respiratory failure in sepsis and severe lung infection.

    Scientific studies which directly impact the larger society require an engagement between the scientists and the larger public. With respect to research on climate change, many third-party groups report on scientific findings and thereby serve as an intermediary between the scientist and the public. In many cases, the third-party reporting misinterprets the findings and conveys inaccurate information to the media and the public. To remedy this, many scientists are now taking a more active role in conveying their work directly to interested parties. In addition, some scientists are taking the further step of engaging with the general public to answer basic questions related to climate change - even on sub-topics which are unrelated to scientists' own research. Nevertheless, many scientists are reluctant to engage the general public or the media. The reasons for scientific reticence are varied but most commonly are related to fear of public engagement, concern about the time required to properly engage the public, or concerns about the impact to their professional reputations. However, for those scientists who are successful, these engagement activities provide many benefits. Scientists can increase the impact of their work, and they can help society make informed choices on significant issues, such as mitigating global warming. Here we provide some concrete steps that scientists can take to ensure that their public engagement is successful. These steps include: (1) cultivating relationships with reporters, (2) crafting clear, easy to understand messages that summarize their work, (3) relating science to everyday experiences, and (4) constructing arguments which appeal to a wide-ranging audience. With these steps, we show that scientists can efficiently deal with concerns that would otherwise inhibit their public engagement. Various resources will be provided that allow scientists to continue work on these key steps.

  8. Encouraging Classroom Discussion

    Full Text Available Classroom discussion has the potential to enhance the learning environment and encourages students to become active participants in the educational process. Student participation in classroom discussion has been shown to significantly improve the student learning experience. Research suggests that classroom discussion is an effective method for encouraging student classroom participation and for motivating student learning beyond the classroom. Participation in classroom discussion encourages students to become active collaborators in the learning process, while at the same time providing instructors with a practical method of assessing student learning. Classroom discussion is an effective tool for developing higher-level cognitive skills like critical thinking. Despite the potential discussion holds for student learning, many in academia lament the lack of participation in the classroom. The lack of student participation in classroom discussion is not a recent problem; it is one that has frustrated instructors for decades. Instructors report that some of the more current methods for encouraging classroom discussion can be exasperating and at times non-productive. This two-year study of 510 college and university students provides insight into the reasons why some students do not participate in classroom discussion. This study, which also elicited input from sixteen college and university professors and two high school teachers, offers some suggestions for creating and encouraging an environment conducive to student participation in the classroom.

    Localized provoked vulvodynia (LPV) may have inflammatory etiology. We wanted to find out whether the cell-mediated immune system becomes activated in the vestibular mucosa in LPV. This was a controlled cross-sectional study. Vestibular mucosal specimens were obtained from 27 patients with severe LPV and 15 controls. Detailed clinical history of the patients was obtained. For immunohistochemistry, antibodies against CD3 (T cells), CD20 (B cells), IgA (mucosal plasma cells), CD163 (dendritic cells [DCs]), CD68 (macrophages), and CD117 (mast cells) were employed. Mann-Whitney U test and χ(2) test were used for statistical analyses. More B lymphocytes and mature mucosal IgA-plasma cells were found in patients than in controls (P associated lymphoid tissue analogous to mucosa-associated lymphoid tissue.

    Pelvic floor muscle physical therapy is recommended in clinical guidelines for women with provoked vestibulodynia (PVD). Including isolated or combined treatment modalities, physical therapy is viewed as an effective first-line intervention, yet no systematic review concerning the effectiveness of physical therapy has been conducted. To systematically appraise the current literature on the effectiveness of physical therapy modalities for decreasing pain during intercourse and improving sexual function in women with PVD. A systematic literature search using PubMed, Scopus, CINHAL, and PEDro was conducted until October 2016. Moreover, a manual search from reference lists of included articles was performed. Ongoing trials also were reviewed using clinicaltrial.gov and ISRCTNregistry. Randomized controlled trials, prospective and retrospective cohorts, and case reports evaluating the effect of isolated or combined physical therapy modalities in women with PVD were included in the review. Main outcome measures were pain during intercourse, sexual function, and patient's perceived improvement. The literature search resulted in 43 eligible studies including 7 randomized controlled trials, 20 prospective studies, 5 retrospective studies, 6 case reports, and 6 study protocols. Most studies had a high risk of bias mainly associated with the lack of a comparison group. Another common bias was related to insufficient sample size, non-validated outcomes, non-standardized intervention, and use of other ongoing treatment. The vast majority of studies showed that physical therapy modalities such as biofeedback, dilators, electrical stimulation, education, multimodal physical therapy, and multidisciplinary approaches were effective for decreasing pain during intercourse and improving sexual function. The positive findings for the effectiveness of physical therapy modalities in women with PVD should be investigated further in robust and well-designed randomized controlled trials

    This study aims to shed light on the changes provoked by boiling, steaming and sous-vide cooking on the lipids and volatile profile of farmed and wild European sea bass meat. None of the cooking techniques provoked changes due to hydrolytic or oxidation processes detectable by 1 H NMR on sea bass lipids. The lipid profile of main and minor lipidic components was maintained after cooking. However, study by SPME-GC/MS evidenced that steaming and sous-vide cooking modified the volatile profile of sea bass meat, especially in farmed specimens. The compounds generated came from the occurrence, to a very small extent, of lipid and protein degradation. By contrast, boiling scarcely modified the initial characteristics of raw sea bass. Thus, from a sensory point of view and considering the odour-active compounds generated, steaming and sous-vide cooking provoked more noticeable changes than boiling, especially in farmed sea bass meat.

    A representative of Finishing Enterprises, the world's largest manufacturer of intrauterine contraceptive devices (IUDs), discusses how to alter the balance of incentives-disincentives to expedite the development of HIV vaccines for international evaluation. Three main disincentives exist for private manufacturers in the United States to develop a new HIV vaccine to be used in developing countries, outside the profitable North American and western European markets: 1) low profit margin because of limited money, time, and resources. Medium and large-sized corporations are more concerned with a high return on their investment owing to stockholder pressure than with the human benefit of that investment. 2) Lengthy regulatory approval process. The current regulatory process in the US is tedious, time-consuming, and costly. 3) Liability risk. The United States is the most litigious society in the world. Suits filed against US corporations involved in drug manufacture incur legal defence costs, which make an already low profit margin HIV vaccine even lower. Finishing Enterprises' IUD program aimed at providing the safest and most effective IUD at an affordable price in a socially responsible way. The Population Council developed the Copper T and retained the patent rights. They and other international health authorities, such as the World Health Organization, conducted or monitored international clinical trials to determine safety and efficacy. Private foundations and public donor agencies funded these activities. When donor agencies committed to volume purchases for their commodity programs, Finishing Enterprises could commit to volume pricing. Whenever high-margin private sector sales occur, Population Council receives a royalty payment. Thus, the disincentives were overcome: 1) Low profit margin was less an issue for a small, private company created specifically to manufacture IUDs and guaranteed volume orders. 2) Lengthy regulatory approval processes were avoided by

    The roundtable discussion began with remarks by the chairman who pointed out the complicated nature of plutonium chemistry. Judging from the papers presented at this symposium, he noticed a pattern which indicated to him the result of diminished funding for investigation of basic plutonium chemistry and funding focused on certain problem areas. Dr. G.L. silver pointed to plutonium chemists' erroneous use of a simplified summary equation involving the disproportionation of Pu(EV) and their each of appreciation of alpha coefficients. To his appreciation of alpha coefficients. To his charges, Dr. J.T. Bell spoke in defense of the chemists. This discussion was followed by W.W. Schulz's comments on the need for experimental work to determine solubility data for plutonium in its various oxidation states under geologic repository conditions. Discussion then turned to plutonium pyrachemical process with Dana C. Christensen as the main speaker. This paper presents edited versions of participants' written version

    As students and practitioners we are taught about the treatment and causative factors of medial shin pain, in particular' shin splints' or the more recent term; medial tibial stress syndrome (MTSS). During the years there have been many theories, conjecture and misunderstandings about the mechanisms of 'shin splints/medial tibial stress syndrome' however the ramifications of these mechanisms on how massage treatment is delivered have not being discussed. The evidence for the treatment of MTSS is largely clinical with little evidence of any treatment being proven to be effective in treating MTSS. The aim of this article is to present a summary of the mechanisms of MTSS and a commentary to provoke thought about the way massage therapy is used in the treatment of MTSS based on these mechanisms.

    The panel discussion opened with a question concerning whether true quantification of myocardial sympathetic presynaptic function or receptor density can be obtained with currently available radiopharmaceuticals. What are the relative advantages of the two general approaches that have been proposed for quantification: (1) The assessment of tracer distribution volume in tissue following bolus injection and (2) quantification based on tracer displacement kinetics following administration of excess unlabeled tracer. It was pointed out that tracer kinetics for the delineation of presynaptic and postsynaptic binding sites by radiopharmaceuticals or radiolabeled receptor antagonists are rather complex, reflecting several physiologic processes that are difficult to separate. Several approaches were examined. The possibility of regional definition of receptor density by PET was questioned and it was noted that regions of interest can be applied to calculate regional receptor kinetics. However, due to the limited spatial resolution of PET, only average transmural values can be determined. The discussion then turned to the discrepancy between the known sparse parasympathetic innervation of the heart and the high density of muscarinic receptors observed with PET. Experiences with MIBG imaging were reported, including uptake in the transplanted heart and interaction of drugs with MIBG uptake

    2008-06-01

    The concept of 'empowerment' is used frequently in a number of professional areas, from psychotherapy to social work. But even if the same term is used, it is not always clear if the concept denotes the same goals or the same practice in these various fields. The purpose of this paper is to clarify the discussion and to find a plausible and useful definition of the concept that is suitable for work in various professions. Several suggestions are discussed in the paper, for example control over life or health, autonomy, ability, self-efficacy, self-esteem, and freedom, and it is concluded that there are two plausible complementary uses, one as a goal and one as a process or approach. Empowerment as a goal is to have control over the determinants of one's quality of life, and empowerment as a process is to create a professional relation where the client or community takes control over the change process, determining both the goals of this process and the means to use.

    Primary adrenal insufficiency is an endocrine disorder characterized by cortisol and aldosterone deficiency caused by destruction of the adrenal cortex. Adrenal crisis is a medical emergency with acute symptoms: nausea, vomiting, abdominal pain, fever, hypoglycemia, seizures, hypovolemic shock, and cardiovascular failure. It occurs in patients with chronic adrenal insufficiency who are exposed to additional stress, such as infection, trauma, or surgical procedures. Dental infection is a possible cause of adrenal crisis in patients with chronic adrenal insufficiency, so pediatric endocrinologists and pediatric dentists should be aware of this risk. The purpose of this report was to present a 6-year-old patient in whom Addison disease was diagnosed through adrenal crisis provoked by dental infection. The patient was treated with intravenous rehydration, intravenous hydrocortisone and antibiotics, and extraction of the infected primary tooth. Multidisciplinary approach and collaboration between the pediatric endocrinologist and the pediatric dentist are necessary to enable adequate medical and dental treatment in children with primary adrenal insufficiency.

    One of the features of metabolic syndrome caused by liquid fructose intake is an impairment of redox status. We have investigated whether maternal fructose ingestion modifies the redox status in pregnant rats and their fetuses. Fructose (10% wt/vol) in the drinking water of rats throughout gestation, leads to maternal hepatic oxidative stress. However, this change was also observed in glucose-fed rats and, in fact, both carbohydrates produced a decrease in antioxidant enzyme activity. Surprisingly, mothers fed carbohydrates displayed low plasma lipid oxidation. In contrast, fetuses from fructose-fed mothers showed elevated levels of plasma lipoperoxides versus fetuses from control or glucose-fed mothers. Interestingly, a clearly augmented oxidative stress was observed in placenta of fructose-fed mothers, accompanied by a lower expression of the transcription factor Nuclear factor-erythroid 2-related factor-2 (Nrf2) and its target gene, heme oxygenase-1 (HO-1), a potent antioxidant molecule. Moreover, histone deacetylase 3 (HDAC3) that has been proposed to upregulate HO-1 expression by stabilizing Nrf2, exhibited a diminished expression in placenta of fructose-supplemented mothers. Maternal fructose intake provoked an imbalanced redox status in placenta and a clear diminution of HO-1 expression, which could be responsible for the augmented oxidative stress found in their fetuses. © 2016 WILEY-VCH Verlag GmbH & Co.

    Overdose administration of sibutramine, a serotonin-noradrenalin reuptake inhibitor, is considered to elicit severe side effects including hypertension, whose pathogenic mechanism remains unclear. Here, we found that 48-h incubation with >10μM sibutramine provokes apoptosis of human aortic endothelial (HAE) cells. Treatment with the lethal concentration of sibutramine facilitated production of reactive oxygen species (ROS), altered expression of endoplasmic reticulum stress response genes (heat shock protein 70 and C/EBP homologous protein), and inactivated 26S proteasome-based proteolysis. The treatment also decreased cellular level of nitric oxide (NO) through lowering of expression and activity of endothelial NO synthase. These results suggest that ROS production and depletion of NO are crucial events in the apoptotic mechanism and may be linked to the pathogenesis of vasoconstriction elicited by the drug. Compared to sibutramine, its metabolites (N-desmethylsibutramine and N-didesmethylsibutramine) were much less cytotoxic to HAE cells, which hardly metabolized sibutramine. In contrast, both the drug and metabolites showed low cytotoxicity to hepatic HepG2 cells with high metabolic potency and expression of cytochrome P450 (CYP) 3A4. The cytotoxicity of sibutramine to HepG2 and Chang Liver cells was remarkably augmented by inhibition and knockdown of CYP3A4. This study also suggests an inverse relationship between sibutramine cytotoxicity and CYP3A4-mediated metabolism into the N-desmethyl metabolites. Copyright © 2016 Elsevier Inc. All rights reserved.

    The authors assessed the relationships between the duration of loss of consciousness (dLOC) during tilt testing-induced syncope (TTS) and demographics, medical history as well as tilt testing results. Previous research focused on the relevance of the type of neurocardiogenic reaction during TTS. The importance of dLOC has not been assessed so far. The study was carried out in 274 patients with suspected neurally mediated syncope and total loss of consciousness during tilt testing. The syncope burden, demographics, and data regarding spontaneous syncope orTTS were compared between group I with dLOC > or =47 seconds and group 2 with dLOC <47 seconds. Medical history revealed that patients in group I had more syncopal spells, more frequent syncope-related traumatic injuries, urine incontinence, jerking movements and typical vasovagal history than in group 2. Moreover, group I patients had more frequently a cardioinhibitory type of reaction and a shorter active phase duration. In addition, they manifested more frequent accompanying cerebral hypoperfusion signs and reproduction of symptoms during TTS than patients in group 2. The loss of consciousness during tilt testing-induced syncope differs in terms of duration among patients with neurally mediated syncope. The dLOC during TTS is associated with medical history and tilt-testing data which confirm the vasovagal aetiology of spontaneous events. The longer dLOC suggests deeper cerebral haemodynamic disturbances during either spontaneous or provoked syncope.

    Once anticoagulation is stopped, the risk of recurrent venous thromboembolism (VTE) over years after a first episode is consistently around 30%. This risk is higher in patients with unprovoked than in those with (transient) provoked VTE, and among the latter in patients with medical than in those with surgical risk factors. Baseline parameters that have been found to be related to the risk of recurrent VTE are the proximal location of deep-vein thrombosis, obesity, old age, male sex and non-0 blood group, whereas the role of inherited thrombophilia is controversial. The persistence of residual vein thrombosis at ultrasound assessment has consistently been shown to increase the risk, as do persistently high values of D-dimer and the early development of the post-thrombotic syndrome. Although the latest international guidelines suggest indefinite anticoagulation for most patients with the first episode of unprovoked VTE, strategies that incorporate the assessment of residual vein thrombosis and D-dimer have the potential to identify subjects in whom anticoagulation can be safely discontinued. Moreover, new opportunities are offered by a few emerging anti-Xa and anti-IIa oral compounds, which are likely to induce fewer haemorrhagic complications than vitamin K antagonists while preserving the same effectiveness; and by low-dose aspirin, which has the potential to prevent the occurrence of both venous and arterial thrombotic events.

    Full Text Available Repetitive mild traumatic brain injury (rmTBI provokes behavioral and cognitive changes. But the study about electrophysiologic findings and managements of rmTBI is limited. In this study, we investigate the effects of anodal transcranial direct current stimulation (tDCS on rmTBI. Thirty-one Sprague Dawley rats were divided into the following groups: sham, rmTBI, and rmTBI treated by tDCS. Animals received closed head mTBI three consecutive times a day. Anodal tDCS was applied to the left motor cortex. We evaluated the motor-evoked potential (MEP and the somatosensory-evoked potential (SEP. T2-weighted magnetic resonance imaging was performed 12 days after rmTBI. After rmTBI, the latency of MEP was prolonged and the amplitude in the right hind limb was reduced in the rmTBI group. The latency of SEP was delayed and the amplitude was decreased after rmTBI in the rmTBI group. In the tDCS group, the amplitude in both hind limbs was increased after tDCS in comparison with the values before rmTBI. Anodal tDCS after rmTBI seems to be a useful tool for promoting transient motor recovery through increasing the synchronicity of cortical firing, and it induces early recovery of consciousness. It can contribute to management of concussion in humans if further study is performed.

    In recognition of the potential benefits of ethanol and the merits of encouraging value-added agricultural development, a committee was formed to develop options for the role of the Ontario Ministry of Agriculture and Food in the further development of the ethanol industry in Ontario. A consultation with interested parties produced a discussion paper which begins with an outline of the role of ethanol as an alternative fuel. Ethanol issues which require industry consideration are presented, including the function of ethanol as a gasoline oxygenate or octane enhancer, environmental impacts, energy impacts, agricultural impacts, trade and fiscal implications, and regulation. The ethanol industry and distribution systems in Ontario are then described. The current industry consists of one ethanol plant and over 30 retail stations. The key issue for expanding the industry is the economics of producing ethanol. At present, production of ethanol in the short term depends on tax incentives amounting to 23.2 cents/l. In the longer term, a significant reduction in feedstock costs and a significant improvement in processing technology, or equally significant gasoline price increases, will be needed to create a sustainable ethanol industry that does not need incentives. Possible roles for the Ministry are identified, such as support for ethanol research and development, financial support for construction of ethanol plants, and active encouragement of market demand for ethanol-blended gasolines

To do this, we used a relatively novel source of qualitative data--comments posted on-line in response to news articles on a particular topic. This study analysed 1,796 comments posted in response to 12 articles dealing with H1N1 vaccine on websites of three major Canadian news sources. Articles were selected based on topic and number of comments. A second objective was to assess the extent to which on-line comments can be used as a reliable data source to capture public attitudes during a health crisis. The following seven themes were mentioned in at least 5% of the comments (% indicates the percentage of comments that included the theme: fear of H1N1 (18.8%; responsibility of media (17.8%; government competency (17.7%; government trustworthiness (10.7%; fear of H1N1 vaccine (8.1%; pharmaceutical companies (7.6%; and personal protective measures (5.8%. It is assumed that the more frequently a theme was mentioned, the more that theme influenced decision making about vaccination.

    Provoked vestibulodynia (PVD) is a common genital pain disorder in women that is associated with sexual dysfunction and lowered sexual satisfaction. A potentially applicable cognitive-behavioral model of chronic pain and disability is the fear-avoidance model (FAM) of pain. The FAM posits that cognitive variables, such as pain catastrophizing, fear, and anxiety lead to avoidance of pain-provoking behaviors (eg, intercourse), resulting in continued pain and disability. Although some of the FAM variables have been shown to be associated with PVD pain and sexuality outcomes, the model as a whole has never been tested in this population. An additional protective factor, pain self-efficacy (SE), is also associated with PVD, but has not been tested within the FAM model. Using a 2-year longitudinal design, we examine (1) whether initial levels (T1) of the independent FAM variables and pain SE were associated with changes in pain, sexual function, and sexual satisfaction over the 2-year time period; (2) the prospective contribution of changes in cognitive-affective (FAM) variables to changes in pain, and sexuality outcomes; and (3) whether these were mediated by behavioral change (avoidance of intercourse). A sample of 222 women with PVD completed self-report measures of FAM variables, SE, pain, sexual function, and sexual satisfaction at time 1 and at a 2-year follow-up. Structural equation modeling with Latent Difference Scores was used to examine changes and to examine mediation between variables. Questionnaires included the Pain Catastrophizing Scale, McGill Pain Questionnaire, Trait Anxiety Inventory, Pain Self-Efficacy Scale, and Global Measure of Sexual Satisfaction, Female Sexual Function Index. Participants who reported higher SE at T1 reported greater declines in pain, greater increases in sexual satisfaction, and greater declines in sexual function over the 2 time points. The overall change model did not support the FAM using negative cognitive

    The cognitive effects of stress are profound, yet it is unknown if the consequences of concurrent multiple stresses on learning and memory differ from those of a single stress of equal intensity and duration. We compared the effects on hippocampus-dependent memory of concurrent, hours-long light, loud noise, jostling and restraint (multimodal stress) with those of restraint or of loud noise alone. We then examined if differences in memory impairment following these two stress types might derive from their differential impact on hippocampal synapses, distinguishing dorsal and ventral hippocampus. Mice exposed to hours-long restraint or loud noise were modestly or minimally impaired in novel object recognition, whereas similar-duration multimodal stress provoked severe deficits. Differences in memory were not explained by differences in plasma corticosterone levels or numbers of Fos-labeled neurons in stress-sensitive hypothalamic neurons. However, although synapses in hippocampal CA3 were impacted by both restraint and multimodal stress, multimodal stress alone reduced synapse numbers severely in dorsal CA1, a region crucial for hippocampus-dependent memory. Ventral CA1 synapses were not significantly affected by either stress modality. Probing the basis of the preferential loss of dorsal synapses after multimodal stress, we found differential patterns of neuronal activation by the two stress types. Cross-correlation matrices, reflecting functional connectivity among activated regions, demonstrated that multimodal stress reduced hippocampal correlations with septum and thalamus and increased correlations with amygdala and BST. Thus, despite similar effects on plasma corticosterone and on hypothalamic stress-sensitive cells, multimodal and restraint stress differ in their activation of brain networks and in their impact on hippocampal synapses. Both of these processes might contribute to amplified memory impairments following short, multimodal stress.

    Research suggests that increased tension in the pelvic floor muscles of women with provoked vestibulodynia (PVD, the most common form of chronic vulvar pain) may play an important role in maintaining and exacerbating their pain. However, no prospective studies of pelvic floor physical therapy (PFPT) for PVD have been carried out. This study prospectively examined the effectiveness of a PFPT intervention in treating the pain and sexual and psychological components of PVD, and determined predictors of greater treatment success. Thirteen women with PVD completed eight sessions of PFPT. Participants were assessed at pre- and post-treatment via gynecological examinations, vestibular pain threshold testing, structured interviews, and standardized questionnaires. A 3-month follow-up interview assessed any further changes. Outcome measures included: vestibular pain thresholds, gynecological examination and intercourse pain ratings, sexual function and intercourse frequency, mental health, negative pain cognitions, and success rates. Following treatment, participants had significantly higher vestibular pain thresholds and significantly lower pain ratings during the gynecological examination. Participants reported significant reductions in pain intensity during intercourse and were able to engage in significantly more pain-free activities. Although overall sexual function significantly improved, various components of sexual function and frequency of intercourse did not. Participants' mental health did not significantly improve; however, pain catastrophizing and pain-related anxiety significantly decreased. The treatment was considered to be successful for 10 of the 13 participants, and predictors of greater treatment success included greater reductions in helplessness and a longer period of time in treatment. Results provide preliminary support for the effectiveness of PFPT in treating the pain of PVD, as well as some of the sexual and cognitive correlates of PVD. The

    Sexual pain secondary to provoked vestibulodynia (PVD) is a chronic pain condition affecting up to 16% of women. Women with PVD may report other chronic pain conditions. The goals of this study were (1) to identify the prevalence of self-reported chronic pain conditions in a sample of women with a diagnosis of PVD and seeking treatment, and (2) to compare demographic and clinical characteristics and health care needs of women with PVD alone and women with PVD and two or more self-reported chronic pain conditions. We assessed the characteristics of 236 women with PVD alone and 55 women with PVD and comorbid chronic pain using a standardized questionnaire, the Beck Depression Inventory, the State-Trait Anxiety Inventory, the Pain Vigilance and Awareness Questionnaire, and the Female Sexual Distress Scale. Compared with women with PVD alone, women with PVD and other concurrent pain reported a significantly longer duration of pain, pain radiating to other parts of the vulva, and pain interfering in a variety of daily activities. This group was also significantly more likely to have seen more gynaecologists, and to have had more office visits with their gynaecologist than women with PVD alone. They were more likely to have tried anticonvulsants, antidepressants, and stress/relaxation therapy for their PVD and were also more likely to have allergies and skin sensitivities. Finally, this group of women had higher symptoms of depression, trait anxiety, and showed a trend towards more pain vigilance. Taken together, these findings suggest that physicians caring for women with PVD and concurrent chronic pain must be alert to the potentially greater health needs among this subsample of women.

    Alzheimer's disease (AD) is a primary degenerative disease that progressively affects all brain functions, with devastating consequences for the patient, the patient's family and society. Rest regional cerebral blood flow (rCBF) could have a strategic role in differentiating between AD patients and normal controls, but its use for this purpose has a low discriminatory capacity. The purpose of this study was to evaluate whether the diagnostic sensitivity of rCBF single-photon emission computed tomography (SPECT) could be increased by using an episodic memory task provocation, i.e. memory-provoked rCBF-SPECT (MP-SPECT). Eighteen persons (73.2±4.8 years) with mild AD and 18 healthy elderly (69.4±3.9 years) were included in the study. The subjects were injected with 99m Tc-hexamethylpropylene amine oxime (HMPAO) during memory provocation with faces and names, followed by an rCBF-SPECT study. The rCBF 99m Tc-HMPAO SPECT images were analysed using statistical parametric mapping (SPM2). Peaks with a false discovery rate corrected value of 0.05 were considered significant. On MP-SPECT, the AD group showed a significant rCBF reduction in the left parietal cortex in comparison with healthy elderly. At rest, no significant group differences were seen. Memory provocation increased the sensitivity of rCBF-SPECT for the detection of AD-related blood flow changes in the brain at the group level. Further studies are needed to evaluate MP-SPECT as a diagnostic tool at the individual level. If a higher sensitivity for AD at the individual level is verified in future studies, a single MP-SPECT study might be sufficient in the clinical setting. (orig.)

    Provoked vestibulodynia (PVD) is a common vulvovaginal pain condition that negatively impacts women's psychological and sexual well-being. Controlled studies have found that women with PVD report greater negative and less positive cognitions about penetration; however, associations between these types of cognitions and women's pain and sexual well-being remain unknown. Further, researchers have yet to examine how interpersonal variables such as sexual communication may impact the association between women's penetration cognitions and PVD outcomes. We examined associations between vaginal penetration cognitions and sexual satisfaction, sexual function, and pain in women with PVD, as well as the moderating role of sexual communication. Seventy-seven women (M age = 28.32, SD = 6.19) diagnosed with PVD completed the catastrophic and pain cognitions and positive cognitions subscales of the Vaginal Penetration Cognition Questionnaire, as well as the Dyadic Sexual Communication Scale. Participants also completed measures of sexual satisfaction, sexual function, and pain. Dependent measures were the (i) Global Measure of Sexual Satisfaction Scale; (ii) Female Sexual Function Index; and (iii) Present Pain Intensity scale of the McGill Pain Questionnaire, with reference to pain during vaginal intercourse. Women's lower catastrophic and pain cognitions, higher positive cognitions, and higher sexual communication were each uniquely associated with higher sexual satisfaction and sexual function. Lower catastrophic and pain cognitions also were associated with women's lower pain. For women who reported higher sexual communication, as positive cognitions increased, there was a significantly greater decrease in pain intensity during intercourse compared to women who reported lower levels of sexual communication. Findings may inform cognitive-behavioral interventions aimed at improving the pain and sexual well-being of women with PVD. Targeting the couple's sexual communication

    Evidence from studies of provocative motion indicates that motion sickness is tightly linked to the disturbances of thermoregulation. The major aim of the current study was to determine whether provocative visual stimuli (immersion into the virtual reality simulating rides on a rollercoaster) affect skin temperature that reflects thermoregulatory cutaneous responses, and to test whether such stimuli alter cognitive functions. In 26 healthy young volunteers wearing head-mounted display (Oculus Rift), simulated rides consistently provoked vection and nausea, with a significant difference between the two versions of simulation software (Parrot Coaster and Helix). Basal finger temperature had bimodal distribution, with low-temperature group (n=8) having values of 23-29 °C, and high-temperature group (n=18) having values of 32-36 °C. Effects of cybersickness on finger temperature depended on the basal level of this variable: in subjects from former group it raised by 3-4 °C, while in most subjects from the latter group it either did not change or transiently reduced by 1.5-2 °C. There was no correlation between the magnitude of changes in the finger temperature and nausea score at the end of simulated ride. Provocative visual stimulation caused prolongation of simple reaction time by 20-50 ms; this increase closely correlated with the subjective rating of nausea. Lastly, in subjects who experienced pronounced nausea, heart rate was elevated. We conclude that cybersickness is associated with changes in cutaneous thermoregulatory vascular tone; this further supports the idea of a tight link between motion sickness and thermoregulation. Cybersickness-induced prolongation of reaction time raises obvious concerns regarding the safety of this technology. Copyright © 2015 Elsevier Inc. All rights reserved.

  15. A comprehensive analysis of gene expression changes provoked by bacterial and fungal infection in C. elegans.

    Full Text Available While Caenorhabditis elegans specifically responds to infection by the up-regulation of certain genes, distinct pathogens trigger the expression of a common set of genes. We applied new methods to conduct a comprehensive and comparative study of the transcriptional response of C. elegans to bacterial and fungal infection. Using tiling arrays and/or RNA-sequencing, we have characterized the genome-wide transcriptional changes that underlie the host's response to infection by three bacterial (Serratia marcescens, Enterococcus faecalis and otorhabdus luminescens and two fungal pathogens (Drechmeria coniospora and Harposporium sp.. We developed a flexible tool, the WormBase Converter (available at http://wormbasemanager.sourceforge.net/, to allow cross-study comparisons. The new data sets provided more extensive lists of differentially regulated genes than previous studies. Annotation analysis confirmed that genes commonly up-regulated by bacterial infections are related to stress responses. We found substantial overlaps between the genes regulated upon intestinal infection by the bacterial pathogens and Harposporium, and between those regulated by Harposporium and D. coniospora, which infects the epidermis. Among the fungus-regulated genes, there was a significant bias towards genes that are evolving rapidly and potentially encode small proteins. The results obtained using new methods reveal that the response to infection in C. elegans is determined by the nature of the pathogen, the site of infection and the physiological imbalance provoked by infection. They form the basis for future functional dissection of innate immune signaling. Finally, we also propose alternative methods to identify differentially regulated genes that take into account the greater variability in lowly expressed genes.

    Full Text Available Abstract Background Provoked vestibulodynia (PVD is a pain disorder localized in the vestibular mucosa. It is the most common cause of dyspareunia among young women and it is associated with general pain hypersensitivity and other chronic pain conditions. Polymorphism in the guanosine triphosphate cyclohydrolase (GCH1 gene has been found to influence general pain sensitivity and the risk of developing a longstanding pain condition. The aim of this study was to investigate GCH1-polymorphism in women with PVD and healthy controls, in correlation to pain sensitivity. Results We found no correlation between the previously defined pain-protective GCH1-SNP combination and the diagnosis of PVD. Nor any correlation with pain sensitivity measured as pressure pain thresholds on the arm, leg and in the vestibule, coital pain scored on a visual analog scale and prevalence of other bodily pain conditions among women with PVD (n = 98 and healthy controls (n = 102. However, among patients with current treatment (n = 36, there was a significant interaction effect of GCH1-gene polymorphism and hormonal contraceptive (HC therapy on coital pain (p = 0.04 as well as on pressure pain thresholds on the arm (p = 0.04. PVD patients carrying the specified SNP combination and using HCs had higher pain sensitivity compared to non-carriers. In non-HC-users, carriers had lower pain sensitivity. Conclusions The results of this study gave no support to the hypothesis that polymorphism in the GCH1-gene contributes to the etiology of PVD. However, among patients currently receiving treatment an interaction effect of the defined SNP combination and use of hormonal contraceptives on pain sensitivity was found. This finding offers a possible explanation to the clinically known fact that some PVD patients improve after cessation of hormonal contraceptives, indicating that PVD patients carrying the defined SNP combination of GCH1 would benefit from this

    Women with provoked vestibulodynia (PVD) experience a recurrent vulvo-vaginal pain triggered primarily during sexual intercourse. Although affected couples report adverse effects on their sexual and global romantic relationships, few studies have examined interpersonal factors that may influence their sexual and relationship satisfaction. Cross-sectional studies have shown that greater partner solicitous and negative responses and lower facilitative responses are associated with poorer sexual and relationship satisfaction in women with PVD. The aim of this study was to investigate the within-person associations between partner responses to painful intercourse and the sexual and relationship satisfaction of affected couples. In a dyadic daily experience study, 69 women (M(age) = 28.46, SD = 6.66) diagnosed with PVD and their cohabitating male partners (M(age) = 30.29, SD = 8.13) reported on male partner responses, as well as sexual and relationship satisfaction on sexual intercourse days (M = 6.81; SD = 5.40) over 8 weeks. Dependent measures were the (i) Kansas Marital Satisfaction Scale and (ii) Global Measure of Sexual Satisfaction Scale. On sexual intercourse days when women perceived more facilitative partner responses than usual and on days when they perceived lower negative partner responses than usual, they reported higher sexual and relationship satisfaction. On sexual intercourse days when men reported more solicitous responses than usual, both they and their female partners reported lower sexual satisfaction. Interventions aimed at improving the day-to-day sexual and relationship satisfaction of couples with PVD should target increasing facilitative and decreasing negative and solicitous partner responses. © 2015 International Society for Sexual Medicine.

    Provoked vestibulodynia (PVD) is suspected to be the most frequent cause of vulvodynia in premenopausal women. Previous research has been inconclusive as to whether higher vulvovaginal pain ratings are associated with lower sexual function and satisfaction in women with PVD. Whether pain intensity correlates with sexual impairment is an important question given its implications for treatment recommendations. To examine the associations among self-reported and objective pain measurements, sexual function, and sexual satisfaction in a large combined clinical and community sample of premenopausal women diagnosed with PVD. Ninety-eight women with PVD underwent a cotton-swab test, a vestibular friction pain measurement, and a vestibular pressure-pain threshold measurement. In addition to sociodemographics, participants completed measurements of pain, sexual function, and sexual satisfaction. Self-report measurements were the pain numerical rating scale (0-10), the McGill-Melzack Pain Questionnaire, the Female Sexual Function Index, and the Global Measure of Sexual Satisfaction. Objective measurements were pain during a cotton-swab test, pain during a vestibular friction procedure, and the vestibular pressure-pain threshold measurement. Age and relationship duration were significantly correlated with the Female Sexual Function Index total score (r = -0.31, P sexual function and satisfaction in women with PVD. The findings show that in women with PVD, self-report and objective pain ratings are not associated with sexual function and satisfaction. The results support the biopsychosocial nature of PVD and underscore the importance of a patient-focused multidisciplinary treatment approach for PVD.

    Women with provoked vestibulodynia (PVD) suffer pain at the entry of the vagina elicited by pressure as during vaginal penetration. To quantify vestibular pain, we developed a new instrument, an algometer. The aim of this study was to investigate the test-retest reliability of the algometer and evaluate its convergent validity for vestibular pain assessment in women with PVD. Twenty-six women with PVD participated in the study. Vestibular pain was assessed with the new algometer and the already known vulvalgesiometer during two different sessions 2 to 4 weeks apart. At each session, the pressure pain threshold (PPT) and pressure pain tolerance (PPTol) were measured twice at the 3, 6, and 9 o'clock sites of the vestibule in random order. The test-retest reliability (intra- and inter-session) of the algometer was calculated using the intraclass correlation coefficient (ICC) and standard error of measurement (SEM). Its convergent validity was evaluated by the correlation coefficients between PPTs and PPTols measured by the algometer and those measured with the vulvalgesiometer. Intra-session reliability at all three sites for PPTs and PPTols in both sessions was excellent (ICC = 0.859 to 0.988, P ≤ 0.002). Inter-session reliability was good to excellent (ICC = 0.683 to 0.922, SEM = 15.06 to 47.04 g, P ≤ 0.001). Significant correlations were found between the two tools for all sites for PPTs (r = 0.500 to 0.614, P ≤ 0.009) and PPTols (r = 0.809 to 0.842, P algometer is a reliable and valid instrument for measuring PPTs and PPTols in the vestibular area in women with PVD. This technology is promising for pinpointing treatment mechanisms and efficacy. © 2015 American Academy of Pain Medicine. All rights reserved.

    Provoked vestibulodynia (PVD) is a chronic pelvic pain disorder affecting 16% of the female population. Neuroimaging studies have highlighted central abnormalities in PVD, similar to other chronic pelvic pain disorders, including brain regions involved in sensory processing and modulation of pain. The aim of the study was to determine alterations in the subvoxel, microstructural organization within tissues in PVD compared with healthy control participants (HCs) and a disease control group (irritable bowel syndrome [IBS]). Diffusion tensor imaging magnetic resonance imaging was conducted in 87 age-matched premenopausal women (29 PVD, 29 HCs, 29 IBS). Statistical parameter mapping of fractional anisotropy (FA) and mean diffusivity (MD) maps were used to identify microstructural difference in the brain specific to PVD or shared with IBS. PVD alterations in microstructural organization of the brain were predominantly observed in fibers associated with sensorimotor integration and pain processing that relay information between the thalamus, basal ganglia, sensorimotor, and insular cortex. PVD, compared with HCs, showed extensive increases in the FA of somatosensory and basal ganglia regions. In contrast, PVD and IBS subjects did not show any FA-related group differences. PVD subjects showed greater MD in the basal ganglia compared with HCs (higher MD in the internal capsule and pallidum) and IBS (higher MD in the putamen and pallidum). Increases in MD were associated with increased vaginal muscle tenderness and vulvar pain. The current findings highlight possible shared mechanisms between 2 different pelvic pain disorders, but also highlight the widespread alterations observed specifically in PVD compared with HCs. Alterations in microstructure in PVD were observed in fibers associated with sensorimotor integration and pain processing, which were also associated with increased vaginal muscle tenderness and vulvar pain. These alterations may be contributing to increased

    The cognitive effects of stress are profound, yet it is unknown if the consequences of concurrent multiple stresses on learning and memory differ from those of a single stress of equal intensity and duration. We compared the effects on hippocampus-dependent memory of concurrent, hours-long light, loud noise, jostling and restraint (multimodal stress) with those of restraint or of loud noise alone. We then examined if differences in memory impairment following these two stress types might derive from their differential impact on hippocampal synapses, distinguishing dorsal and ventral hippocampus. Mice exposed to hours-long restraint or loud noise were modestly or minimally impaired in novel object recognition, whereas similar-duration multimodal stress provoked severe deficits. Differences in memory were not explained by differences in plasma corticosterone levels or numbers of Fos-labeled neurons in stress-sensitive hypothalamic neurons. However, although synapses in hippocampal CA3 were impacted by both restraint and multimodal stress, multimodal stress alone reduced synapse numbers severely in dorsal CA1, a region crucial for hippocampus-dependent memory. Ventral CA1 synapses were not significantly affected by either stress modality. Probing the basis of the preferential loss of dorsal synapses after multimodal stress, we found differential patterns of neuronal activation by the two stress types. Cross-correlation matrices, reflecting functional connectivity among activated regions, demonstrated that multimodal stress reduced hippocampal correlations with septum and thalamus and increased correlations with amygdala and BST. Thus, despite similar effects on plasma corticosterone and on hypothalamic stress-sensitive cells, multimodal and restraint stress differ in their activation of brain networks and in their impact on hippocampal synapses. Both of these processes might contribute to amplified memory impairments following short, multimodal stress. PMID:24589888

    Observing another person experiencing exogenously inflicted pain (e.g. by a sharp object penetrating a finger) modulates the excitability of the observer' primary motor cortex (M1). By contrast, far less is known about the response to endogenously evoked pain such as sudden back pain provoked by lifting a heavy object. Here, participants (n=26) observed the lifting of a heavy object. During this action the actor (1) flexed and extended the legs (LEG), (2) flexed and extended the back (BACK) or (3) flexed and extended the back which caused visible pain (BACKPAIN). Corticomotor excitability was measured by applying a single transcranial magnetic stimulation pulse to the M1 representation of the muscle erector spinae and participants scored their perception of the actor's pain on the numeric pain rating scale (NPRS). The participants scored vicarious pain as highest during the BACKPAIN condition and lowest during the LEG condition. MEP size was significantly lower for the LEG than the BACK and BACKPAIN condition. Although we found no statistical difference in the motor-evoked potential (MEP) size between the conditions BACK and BACKPAIN, there was a significant correlation between the difference in NPRS scores between the conditions BACKPAIN and BACK and the difference in MEP size between these conditions. Participants who believed the vicarious pain to be much stronger in the BACKPAIN than in the BACK condition also exhibited higher MEPs for the BACKPAIN than the BACK condition. Our results indicate that observing how others lift heavy objects facilitates motor representations of back muscles in the observer. Modulation occurs in a movement-specific manner and is additionally modulated by the extent to which the participants perceived the actor's pain. Our findings suggest that movement observation might be a promising paradigm to study the brain's response to back pain. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Overdose administration of sibutramine, a serotonin-noradrenalin reuptake inhibitor, is considered to elicit severe side effects including hypertension, whose pathogenic mechanism remains unclear. Here, we found that 48-h incubation with > 10 μM sibutramine provokes apoptosis of human aortic endothelial (HAE) cells. Treatment with the lethal concentration of sibutramine facilitated production of reactive oxygen species (ROS), altered expression of endoplasmic reticulum stress response genes (heat shock protein 70 and C/EBP homologous protein), and inactivated 26S proteasome-based proteolysis. The treatment also decreased cellular level of nitric oxide (NO) through lowering of expression and activity of endothelial NO synthase. These results suggest that ROS production and depletion of NO are crucial events in the apoptotic mechanism and may be linked to the pathogenesis of vasoconstriction elicited by the drug. Compared to sibutramine, its metabolites (N-desmethylsibutramine and N-didesmethylsibutramine) were much less cytotoxic to HAE cells, which hardly metabolized sibutramine. In contrast, both the drug and metabolites showed low cytotoxicity to hepatic HepG2 cells with high metabolic potency and expression of cytochrome P450 (CYP) 3A4. The cytotoxicity of sibutramine to HepG2 and Chang Liver cells was remarkably augmented by inhibition and knockdown of CYP3A4. This study also suggests an inverse relationship between sibutramine cytotoxicity and CYP3A4-mediated metabolism into the N-desmethyl metabolites. - Highlights: • Treatment with sibutramine, an anorexiant, induces endothelial cell apoptosis. • The apoptotic mechanism includes induction of ROS and NO depletion. • There is an inverse relationship between sibutramine cytotoxicity and its metabolism.

    In December 2007, the Forum on Stakeholder Confidence discussed its theme entitled 'Link between research, development and demonstration (RD and D) and stakeholder confidence'. It was remarked that regulators need a technical demonstration to aid in evaluating the safety case. Local stakeholders appreciate the opportunity to visualise technological arrangements. In both cases, demonstration adds to confidence in the feasibility of solutions. Some believe there is an important role for analogues in communication with stakeholders, if handled with integrity. To explore and benchmark current practices, it was decided to hold a topical session at the 9. regular meeting of the FSC on 4 June 2008 regarding the use of analogues for confidence building. The session opened with an introductory presentation by the session rapporteur. This incorporated input provided for the purpose by FSC members in cooperation with their country's representative to the NEA RWMC 'Integration Group on the Safety Case'. Three speakers then presented the various uses of analogues by implementers, regulators and scientists to build their own confidence; a fourth speaker dealt with the experience of using natural analogues in public information. The presentations addressed the use of analogues in the field of geological disposal of high-level waste (HLW) and long-lived intermediate level (ILW-LL) radioactive waste. Then the FSC participants split into two working groups for discussion. The outcome of these discussions was reported in plenary on 6 June 2008 and it was agreed to publish proceedings of the session. The present summary, prepared by the session rapporteur with input from the NEA Secretariat, captures the main points heard in the course of the event. It combines data from the formal presentations and remarks made in discussion. The latter represent viewpoints expressed by a group whose primary focus is not natural analogues but rather stakeholder interests. The summary and viewpoints

    Full Text Available In the wake of the protests that took place in mid 2013 in the city of São Paulo, this article investigates some collective and momentary massive occupation processes of the open public spaces in the city’s downtown area, whether under the aegis of the law or beyond the law. It can be said that the observation of intriguing and unstable ways of occupancy and appropriation of the public space – rather than stability of the built landscape – and their constant, momentary, and circumstantial rearrangement was the leitmotif for building a critical reflection on the uncertain paradoxical trends associated with contemporary collective public life. This study analyzed the territory as an inseparable relationship between normative pre-figurations and spontaneous momentary configurations of the urban space through appropriative, constant, and/or occasional flows. From everyday life to the most casual and incidental, what could have been thought based on this relation? Starting from this desubstantiated matter, another epistemological panorama about the present rises, riddled with paradoxalities. Ranging from the predictable, normalized, and standardized to the unexpected, urban space – changes in time – gave rise to a dimension important enough to be considered [and to be thought of] about the public “being” of the territory in some situations and occasions.

    Provoked vestibulodynia (PVD) is a women's genito-pelvic pain condition associated with psychosexual impairments, including depression. Body image (BI) has been found to be different in women with primary (PVD1) and secondary (PVD2) PVD. No controlled study has compared BI in women with PVD1 and PVD2 and investigated its associations with sexual satisfaction, sexual function, and pain. The aims of this study were to (i) compare BI in women with PVD1, PVD2, and asymptomatic controls and (ii) to examine associations between BI and sexual satisfaction, sexual function, and pain during intercourse in women with PVD. Fifty-seven women (20 with PVD1, 19 with PVD2, and 18 controls) completed measures of BI, sexual satisfaction, sexual function, pain during intercourse, and depression. The main outcome measures were (i) Global Measure of Sexual Satisfaction Scale, (ii) Female Sexual Function Index, and (iii) pain numerical rating scale. Controlling for depression, women with PVD1 reported more body exposure anxiety during sexual activities than women with PVD2 and controls F(2,51)=4.23, P=0.02. For women with PVD, more negative BI during sexual activities was associated with lower sexual satisfaction (β=-0.45, P=0.02) and function (β=-0.39, P=0.04) and higher pain during intercourse (β=0.59, P=0.004). More positive body esteem was associated with higher sexual function (β=0.34, P=0.05). Findings suggest that women with PVD1 present more body exposure anxiety during sexual activities than women with PVD2 and asymptomatic women. Body esteem and general attitudes toward women's genitalia were not significantly different between groups. Higher body exposure anxiety during sexual activities was associated with poorer sexual outcomes in women with PVD. Further studies assessing interventions targeting BI during sexual activities in this population are needed, as improving BI during sexual interactions may enhance sexual outcomes in women with PVD. © 2014 International

    Full Text Available The paper deals with forced migration caused by Serb aggression in areas of Croatia and the neighbouring countries. The first part presents the relevant facts relating to Croatia and important for an understanding of the migration flows (some demographic data as well as the basic guidelines of migration policy, legal regulations and most important problems connected with expellees, refugees and displaced persons. The main elements of contemporary migration movements in Croatia are indicated – migration based on economic causes (traditional migration, migration provoked by crisis and war destruction in former Yugoslavia and migration flows that are difficult to register (mainly clandestine crossings of the border of the Republic of Croatia and the irregular labour market. The author states that the expellee, refugee and displaced persons crisis (with psychological and material repercussions began in 1991 and reached a climax in 1992 when Croatia became one of the most pronounced refugee countries in the world, with refugees accounting for about 15% of its population. As the war crisis shifted, the areas from which intense forced migration to and from Croatia resulted also shifted as did the mechanisms for regulating these forced migrations (dual citizenship, transit visas, accords with "third countries" for accepting refugees and expellees, ways of resolving and caring for the refugee-expellee populations in the Republic of Croatia. The author concludes that even after seven years from the start of the aggression against Croatia, this humanitarian crisis among expellees, refugees and displaced persons has not yet finished, as testified by the new military conflict in Kosovo and by many open questions in regard to the future organisation of states in this crisis area as well as the creation of mechanisms for monitoring potential conflicts. A fundamental idea is expressed throughout the paper – i.e. the notion that now it is maybe more

    Problems related to pain during vaginal penetration are complex and the etiology is multi-factorial. It was the aim of the present study to measure whether treatment using desensitization exercises and cognitive behavioral therapy (CBT) for women with provoked vulvodynia (PVD) could increase sexual interest, sexual satisfaction and response whilst decreasing experiences of sexual pain. Sixty women suffering from PVD were treated during a 10-week period with a combination of mucosal desensitization and pelvic floor exercises and CBT. The McCoy Female Sexuality Questionnaire (MFSQ) was used to measure efficacy of the treatment. The Hospital Anxiety and Depression Scale (HADS) was used to measure psychological distress. The primary outcome measurements were changes in scores for the MFSQ and changes in individual items on the MFSQ directly after treatment completion. Secondary outcome measurements were changes in the MFSQ items 6 months after treatment and changes in HADS sub-scales 6 months after treatment. Statistical comparisons of answers to the MFSQ were carried out using the Wilcoxon signed rank test (paired). Validity of the MFSQ in this study was measured by testing one global question about sexuality and total scores on MFSQ using Spearman's correlation test. Study participants reported a statistically significant increase in sexual fantasies, increased sexual pleasure, excitement and vaginal lubrication after treatment was completed. PVD occurred less often which resulted in significantly less avoidance of sexual intercourse, increased frequency of masturbation and intercourse. All improvements were sustained at 6 months after treatment ended. Two questions showed no significant changes, these pertained to the individual's contentment with her partner as a lover and a friend. The anxiety sub-scale of the HADS showed a significantly decreased level of anxiety at 6 months follow-up but no change in the scores on the depression sub-scale. Treatment for PVD

    The positive energy projection operators, just described by Prof. Sucher, convert the sick Hamiltonian, H/sub DC/, into a more robust one which can support bound states. They are however still a subject of some controversy. Prof. Grant pointed out that existing computer codes produce remarkable accuracy in numerical calculations which start from H/sub DC/ (with no projection operators) and so he questioned whether these operators were indeed necessary. In response, it was pointed out by several people in the audience that the codes implicitly limit the Dirac-Hartee-Fock wave functions to a normalizable sub-space and that this operation can be described as a projection operator which has the effect of eliminating the negative energy states which are not normalizable. This operation is however, not any of the three projection operators described by Sucher and so the question arises as to the sensitivity of the results (for the energy and wave functions) to the particular projection operators which are used. This appears to be an open question

    Provoked vestibulodynia is the most common form of vulvodynia. Despite its high prevalence and deleterious sexual, conjugal, and psychological repercussions, effective evidence-based interventions for provoked vestibulodynia remain limited. For a high proportion of women, significant pain persists despite the currently available treatments. Growing evidence suggests that the central nervous system (CNS) could play a key role in provoked vestibulodynia; thus, treatment targeting the CNS, rather than localized dysfunctions, may be beneficial for women suffering from provoked vestibulodynia. In this study, we aim to build on the promising results of a previous case report and evaluate whether transcranial direct-current stimulation, a non-invasive brain stimulation technique targeting the CNS, could be an effective treatment option for women with provoked vestibulodynia. This single-center, triple-blind, parallel group, randomized, controlled trial aims to compare the efficacy of transcranial direct-current stimulation with sham transcranial direct-current stimulation in women with provoked vestibulodynia. Forty women diagnosed with provoked vestibulodynia by a gynecologist, following a standardized treatment protocol, are randomized to either active transcranial direct-current stimulation treatment for ten sessions of 20 minutes at an intensity of 2 mA or sham transcranial direct-current stimulation over a 2-week period. Outcome measures are collected at baseline, 2 weeks after treatment and at 3-month follow-up. The primary outcome is pain during intercourse, assessed with a numerical rating scale. Secondary measurements focus on the sexual function, vestibular pain sensitivity, psychological distress, treatment satisfaction, and the patient's global impression of change. To our knowledge, this study is the first randomized controlled trial to examine the efficacy of transcranial direct-current stimulation in women with provoked vestibulodynia. Findings from this

    During neurocardiogenic reaction provoked by tilt testing (TT), different arrhythmias such as sinus bradycardia, sinus arrest, atrioventricular block or junctional rhythm or beats (JR) may occur. The characteristics of the JR during neurocardiogenic reaction have not yet been systematically assessed. It is not known whether the presence of JR during neurocardiogenic reaction is related to clinical characteristics of syncopal patients or the outcome of TT. To assess whether clinical outcome of TT and clinical data are related to the presence of JR during TT. The study group consisted of 532 patients aged 43.3 ± 18.2 years with positive TT, divided into four groups on the basis of the presence of JR and/or a ventricular pause (VP) during neurocardiogenic reaction: group VP(-)/JR(+) - JR present and VP absent, group VP(+)/JR(+) - both JR and VP present, group VP(+)/JR(-) - JR absent and VP present, and group VP(-)/JR(-) - both JR and VP absent. The control group consisted of 53 patients with no history of syncope or presyncope, including 46 patients with negative TT and seven patients with false positive TT. Total loss of consciousness during TT occurred in group VP(-)/JR(+) less frequently than in groups VP(+)/JR(+) and VP(+)/JR(-), and more frequently than in group VP(-)/JR(-) (80% vs 96% vs 94% vs 62%; p 〈 0.05 for both comparisons). Group VP(-)/JR(+) was significantly younger than group VP(-)/JR(-) (37.3 ± 16.3 years vs 45.8 ± 18.9 years; p 〈 0.05) and had a lower number of syncopal events than group VP(+)/JR(+) and VP(+)/JR(-) (median [IQ]: 2.5 (1-6) vs 4 (2-12) and 4 (2-10), respectively; p 〈 0.05) and lower rate of traumatic injuries than group VP(+)/JR(+) and VP(+)/JR(-) (22% vs 45% and 39%, respectively; p 〈 0.05). Logistic regression analysis revealed that the presence of JR was associated with younger age, male gender, history of blood-instrumentation-injection phobia and higher number of syncopal spells in medical history.

    Full Text Available O artigo discute alguns resultados de uma pesquisa qualitativa realizada entre 2009 e 2011 que investigou as trajetórias de jovens participantes do Programa ProJovem Urbano (Programa Nacional de Inclusão de Jovens no ano de 2009, em Belo Horizonte, Minas Gerais. Procurou-se compreender a vivência da condição juvenil pelos participantes do programa a partir de suas experiências de escolarização e trabalho e de seus projetos de futuro, para assim compreender os significados e sentidos do programa para eles. Na primeira etapa da pesquisa, foram aplicados 103 questionários a fim de construir um breve perfil socioeconômico dos alunos. Após o levantamento inicial dos dados, duas turmas foram selecionadas e observadas. Posteriormente, foram selecionados dez jovens para a realização de entrevistas semiestruturadas. A pesquisa revelou uma maioria de mulheres, negros e jovens em condições precárias de trabalho ou desempregados e com uma sociabilidade restrita em relação a outros estratos da população. Evidenciou-se que as desigualdades sociais têm uma importância central nas trajetórias de vida desses jovens, com impactos marcantes em suas experiências atuais e em suas expectativas em relação ao futuro. Com base nesse solo comum, foi possível perceber uma diversidade de experiências a partir das quais são produzidos diferentes significados e motivações em relação à escolarização, o que delimitava também a relação construída com o programa. De uma maneira geral, a busca pela certificação escolar era o principal interesse dos participantes.This paper discusses some of the outcomes of a qualitative research carried out between 2009 and 2011 which investigated the trajectories of young participants in the Program ProJovem Urbano (National Program for Youth Inclusion in 2009, in the city of Belo Horizonte, state of Minas Gerais, in Brazil.

    2010-09-01

    Healthcare professionals, patients and their relatives are expected to discuss resuscitation together. This study aims to identify the differences in the knowledge base and understanding of these parties. Questionnaires examining knowledge and opinion on resuscitation matters were completed during interviews of randomly selected doctors, nurses and the general public. 70% doctors, 24% nurses and 0% of a public group correctly estimated survival to discharge following in-hospital resuscitation attempts. Deficiencies were identified in doctor and nurse knowledge of ethics governing resuscitation decisions. Public opinion often conflicts with ethical guidelines. Public understanding of the nature of cardiopulmonary arrests and resuscitation attempts; and of the implications of a \\'Do Not Attempt Resuscitation (DNAR)\\' order is poor. Television medical dramas are the primary source of resuscitation knowledge. Deficiencies in healthcare professionals\\' knowledge of resuscitation ethics and outcomes may compromise resuscitation decisions. Educational initiatives to address deficiencies are necessary. Parties involved in discussion on resuscitation do not share the same knowledge base reducing the likelihood of meaningful discussion. Public misapprehensions surrounding resuscitation must be identified and corrected during discussion.

    Medical tourism is a growing phenomenon. This review of the literature maps current knowledge and discusses findings with reference to the UK National Health Service (NHS). Databases were systematically searched between September 2011 and March 2012 and 100 papers were selected for review. The literature shows specific types of tourism depending on treatment, eg, dentistry, cosmetic, or fertility. Patient motivation is complex and while further research is needed, factors beyond cost, including availability and distance, are clearly important. The provision of medical tourism varies. Volume of patient travel, economic cost and benefit were established for 13 countries. It highlights contributions not only to recipient countries' economies but also to a possible growth in health systems' inequities. Evidence suggests that UK patients travel abroad to receive treatment, complications arise and are treated by the NHS, indicating costs from medical travel for originating health systems. It demonstrates the importance of quality standards and holds lessons as the UK and other EU countries implement the EU Directive on cross-border care. Lifting the private-patient-cap for NHS hospitals increases potential for growth in inbound medical tourism; yet no research exists on this. Research is required on volume, cost, patient motivation, industry, and on long-term health outcomes in medical tourists. © 2014 International Society of Travel Medicine.

    1983-03-01

    The effects of clonidine hydrochloride, an agent effective in suppressing other types of flushing reactions, were investigated in patients with erythematotelangiectatic rosacea. Clonidine hydrochloride, 0.05 mg, was given orally twice daily for two weeks. Mean arterial BP was not altered during clonidine treatment. Flushing reactions provoked with water at 60 degrees C, red wine, and chocolate were not suppressed during clonidine treatment. Clonidine did lead to malar hypothermia. It may be that any treatment benefit obtained from the reduction in vascular reactivity by clonidine in rosacea is offset by the malar hypothermia.

    Blood coagulation was enhanced and all factors (total, enzyme, and non-enzyme) of the fibrinolytic system were suppressed in rats in 60 min after forced swimming test. Argininecontaining tetrapeptide glyproline Arg-Pro-Gly-Pro administered prior to this test activated fibrinolysis and prevented hypercoagulation. Administration of this peptide in 5 min after swimming test also enhanced anticoagulant, fibrinolytic, and antithrombotic activity of the blood. Therefore, glyproline Arg-Pro-Gly-Pro exerted both preventive and curative effects on the hemostasis system and prevented enhancement of blood coagulation provoked by emotional stress modeled by forced swimming test.

    In this article are evoked the question of nuclear safety and the public opinion, from the beginning of nuclear power plants in 1954 where a peaceful use of nuclear energy is developed in minds. If the aim was to avoid any important accident, the Three Miles Island accident and more recently the Chernobyl accident provoked a shock in public opinion and marked a peak of nuclear controversy. From this point, the policy of transparence and a best information of the public taken as a partner are necessary to maintain the dialogue. (N.C.)

  6. Perceiving the target's state or state provoked by the target? An analysis of the descriptive and evaluative knowledge in person perception.

    Mignon, Astrid; Mollaret, Patrick

    2012-12-01

    In line with the theory of traits as generalized affordances, the present article argues that target's states (TSs) and states provoked by a target (other's states (OSs) towards target) are two components of the meaning of traits referring, respectively, to a descriptive and to an evaluative knowledge of people. A preliminary study confirmed that TS and OS were equally representative of a trait. Two studies were designed to study the effects of practising the use of traits as either TS or OS categories (an induction procedure) on a subsequent person perception task, requiring participants to rate photographed targets on a series of traits. Results show that both the differentiation between targets and evaluative consistency of ratings were enhanced under the OS condition compared to TS and control (with no practice of traits) conditions. Importantly, Study 2 tends to show that the effects of the induction procedure are not limited to the practised traits but also generalize to unpractised traits. Implications of these findings for social perception research are discussed. ©2011 The British Psychological Society.

    Background In acutely ill patients with new onset hyperglycaemia, plasma glucose cannot reliably distinguish between stress hyperglycaemia and undiagnosed diabetes mellitus. We, therefore, investigated the diagnostic reliability of glycated haemoglobin (HbA1c) in acute illness by prospectively evaluating the effect of the systemic inflammatory response, as provoked by elective orthopaedic surgery, on HbA 1c . Methods HbA 1c and serum C-reactive protein concentrations were compared before and two days after elective knee or hip surgery in 30 patients without diabetes. C-reactive protein was used to assess the systemic inflammatory response. Results The mean (standard deviation) serum C-reactive protein increased following surgery (4.8 [7.5] vs. 179.7 [61.9] mg/L; P<0.0001). HbA 1c was similar before and after surgery (39.2 [5.4] vs. 38.1 [5.1] mmol/moL, respectively; P = 0.4363). Conclusions HbA 1c is unaffected within two days of a systemic inflammatory response as provoked by elective orthopaedic surgery. This suggests that HbA 1c may be able to differentiate newly presenting type 2 diabetes mellitus from stress hyperglycaemia in acutely ill patients with new onset hyperglycaemia.

    This study was conducted to determine the effects of extracts obtained from both normal and denervated muscles on different muscle types. Wistar rats were used and were divided into a control group and four experimental groups. Each experimental group was treated intraperitoneally during 10 consecutive days with a different extract. These extracts were obtained from normal soleus muscle, denervated soleus, normal extensor digitorum longus, and denervated extensor digitorum longus. Following treatment, the soleus and extensor digitorum longus muscles were obtained for study under optic and transmission electron microscope; morphometric parameters and myogenic responses were also analyzed. The results demonstrated that the treatment with normal soleus muscle and denervated soleus muscle extracts provoked hypertrophy and increased myogenic activity. In contrast, treatment with extracts from the normal and denervated EDL had a different effect depending on the muscle analyzed. In the soleus muscle it provoked hypertrophy of type I fibers and increased myogenic activity, while in the extensor digitorum longus atrophy of the type II fibers was observed without changes in myogenic activity. This suggests that the muscular responses of atrophy and hypertrophy may depend on different factors related to the muscle type which could be related to innervation.

    Exposure to a sports celebrity through media and sporting events can have important influences on a public health issue associated with that celebrity. The battle against drug use by Argentinean soccer icon Diego Maradona has provoked concerns about drug abuse and prevention in Argentina, particularly among young people. The present study analyzes how two forms of involvement with Maradona affected the public's concern and perceptions of drug use after Maradona's drug-related health crisis in 2004. Results indicate that those who had a greater degree of parasocial interaction with Maradona were more likely to have an increased awareness of drug abuse, a greater personal concern about drug abuse, abstained from drug use, and more strongly support drug abuse prevention programs. In contrast, identification with Maradona had a mitigating effect on drug use prevention. Implications of these findings regarding the influence of sports celebrities on substance abuse are discussed.

    Full Text Available Feedback theory proposes that feedback influences the behavior of a system and its parts and that is governed by rules. This exploratory study attempts to test this theory in a graduate-level class on leadership theory. Twelve students were asked to participate in five online discussions, each lasting one week. The questions for each discussion were selected to be provocative and rich, without having any correct answer. At the end of the discussion, students were asked to indicate which posting and poster they felt was “best” or most valuable and why they felt the posting was “best.” There is mixed evidence that the voting influenced subsequent postings; some individuals did improve while others were consistently good or poor posters. Students selected postings that were (in declining frequency of occurrence: thoughtful or thought-provoking, well written or justified, uplifting, presented new information, same as their own opinions, changed me, or complex. These reasons are similar to those of the instructor, although the students’ difficulty in choosing and rationalizing a choice and the frequency at which students chose posts that captured their own thoughts and opinions are of some concern. This study provides some evidence that these graduate students could evaluate their own discussions without the instructor intruding or dictating an evaluation scheme, although this may not be true for other groups of online students.

    The current study is concerned with the different types of gender stereotypes that participants may draw upon when exposed to news stories about intimate partner violence (IPV). We qualitatively analyzed open-ended responses examining four types of gender stereotypes-aggression, emotional, power and control, and acceptability of violence. We offer theoretical implications that extend past research on intimate terrorism and situational couple violence, the gender symmetry debate, and how stereotypes are formed. We also discuss practical implications for journalists who write stories about IPV and individuals who provide services to victims and perpetrators. © The Author(s) 2016.

    This paper is a response to a recent article dealing with the concept of value-free sociology by Donald Black. It argues that while a defence of Weber's position on the role of values in sociological research is necessary and important, what is offered by Black is counter-productive in important respects. This is because it encourages some of the misunderstandings that it is aimed at remedying and, even more importantly, offers a simplistic discussion of what are complex issues. © London School of Economics and Political Science 2014.

    2010-10-01

    Full Text Available Abstract Background Worldwide used pesticides containing different adjuvants like Roundup formulations, which are glyphosate-based herbicides, can provoke some in vivo toxicity and in human cells. These pesticides are commonly found in the environment, surface waters and as food residues of Roundup tolerant genetically modified plants. In order to know their effects on cells from liver, a major detoxification organ, we have studied their mechanism of action and possible protection by precise medicinal plant extracts called Dig1. Methods The cytotoxicity pathways of four formulations of glyphosate-based herbicides were studied using human hepatic cell lines HepG2 and Hep3B, known models to study xenobiotic effects. We monitored mitochondrial succinate dehydrogenase activity and caspases 3/7 for cell mortality and protection by Dig1, as well as cytochromes P450 1A1, 1A2, 3A4 and 2C9 and glutathione-S-transferase to approach the mechanism of actions. Results All the four Roundup formulations provoke liver cell death, with adjuvants having stronger effects than glyphosate alone. Hep3B are 3-5 times more sensitive over 48 h. Caspases 3/7 are greatly activated in HepG2 by Roundup at non-cytotoxic levels, and some apoptosis induction by Roundup is possible together with necrosis. CYP3A4 is specifically enhanced by Roundup at doses 400 times less than used in agriculture (2%. CYP1A2 is increased to a lesser extent together with glutathione-S-transferase (GST down-regulation. Dig 1, non cytotoxic and not inducing caspases by itself, is able to prevent Roundup-induced cell death in a time-dependant manner with an important efficiency of up to 89%, within 48 h. In addition, we evidenced that it prevents Caspases 3/7 activation and CYP3A4 enhancement, and not GST reduction, but in turn it slightly inhibited CYP2C9 when added before Roundup. Conclusion Roundup is able to provoke intracellular disruption in hepatic cell lines at different levels, but a

    Functional brain imaging plays an important role in seizure focus localisation. However, truly ictal single-photon emission tomography (SPET) studies are not routinely performed owing to technical problems associated with the use of tracers and methodological and logistical difficulties. In this study we tried to resolve both of these issues by means of a new procedure: technetium-99m ethyl cysteinate dimer (ECD) brain SPET performed during seizures pharmacologically provoked with pentylenetetrazol, a well-known central and respiratory stimulant. We studied 33 drug-resistant epileptic patients. All patients underwent anamnestic evaluation, neuropsychological and psychodynamic assessment, magnetic resonance imaging, interictal and ictal video-EEG monitoring, and interictal and ictal SPET with 99m Tc-ECD. In order to obtain truly ictal SPET, 65 mg of pentylenetetrazol was injected every 2 minutes and, immediately the seizure began, 740 MBq of 99m Tc-ECD was injected. The scintigraphic findings were considered abnormal if a single area of hyperperfusion was present and corresponded to the site of a single area of hypoperfusion at interictal SPET: the ''hypo-hyperperfusion'' SPET pattern. In 27 of the 33 patients (82%), interictal-ictal SPET showed the hypo-hyperperfusion SPET pattern. Video-EEG showed a single epileptogenic zone in 21/33 patients (64%), and MRI showed anatomical lesions in 19/33 patients (57%). Twenty-two of the 27 patients with hypo-hyperperfusion SPET pattern underwent ablative or palliative surgery and were seizure-free at 3 years of follow-up. No adverse effects were noted during pharmacologically provoked seizure. It is concluded that ictal brain SPET performed during pharmacologically provoked seizure provides truly ictal images because 99m Tc-ECD is injected immediately upon seizure onset. Using this feasible procedure it is possible to localise the focus, to avoid the limitations due to the unpredictability of seizures, to avoid pitfalls due

  20. The "Other" Speaks Up. When Social Science (Representations Provoke Reactance from the Field

    Directory of Open Access Journals (Sweden)

    2011-03-01

    Full Text Available This paper addresses science communication problems: How do researchers convey social science representations and findings to the researched? How are the latter described in research reports? How do they react when they read or hear such reports and when they subsequently engage in discourse with researchers? Typically, social science researchers approach a field site with an attitude of curiosity that is unburdened by an immediate pressure to act. The field inhabitants, by contrast, are subject to the practical constraints of these everyday worlds; they identify personally with their milieu and its protagonists, and they are correspondingly sensitive. The present paper describes their defensive reactions, taking as an example the reception of a research project presented at conferences attended by a mixed audience. It highlights the reactions and strategies displayed by the researched in the contexts of discourse and meaning negotiation in response to unwelcome representations. And it offers several interpretations of the interactions between the researchers and the researched. Field members may oppose the revelation of contextual and causal factors construing it as "washing dirty laundry in public". Researchers react to this in their textual representations, and their reactions may take the form of score-settling. The present paper asks how such contradictory, conflict-laden constellations and perspectives in the discourse between the observers and the observed can be productively dealt with.

    Provoked vestibulodynia (PVD) is a common condition characterized by localized, provoked pain that can be present since first vaginal penetration attempt (primary) or can develop after a period of pain-free penetration (secondary). Research has demonstrated psychosocial and psychophysical differences between women with these subtypes of PVD, but the question of whether neural responses to pain also differ remains to be investigated. This study aims to examine whether cognitive, psychophysical, and neural responses to vulvar pressure pain differ between women with PVD1 and PVD2. Women with PVD1 and PVD2 were compared for group differences using multiple modalities, including questionnaires, psychophysical testing, and neuroimaging. Pain ratings were held constant across groups, rather than amount of pressure applied. Demographics, sexual functioning, four questionnaires examining anxiety and catastrophizing, quantitative sensory testing at the vulvar vestibule using a vulvalgesiometer, and functional and structural magnetic resonance imaging (MRI). Findings suggest that women with PVD1 are more anxious and that they catastrophize more about their vulvar and nonvulvar pain than women with PVD2. Overall, MRI results demonstrated structural and functional similarities to other chronic pain findings for both groups of women. Gray matter (GM) density also differed between groups: women with PVD1 showed significant decreases in GM throughout areas associated with pain processing. Functionally, between-groups differences were found during painful vulvar stimulation despite lower pressures applied to the vulva for women with PVD1 because of their heightened sensitivity; the determination of the level of vulvar pressure to elicit pain was based on subjective ratings. Findings are limited by sample size and liberal alpha values; however, future research is certainly warranted based on the preliminary findings of this study suggesting both similarities and differences between

    People often discuss events they have seen and these discussions can influence later recollections. We investigated the effects of factual, emotional, and free retelling discussion on memory recollections of individuals who have witnessed an event. Participants were shown a video, made an initial individual recall, participated in one of the three retelling conditions (emotional versus factual versus free) or a control condition, and then recalled the event individually again. Participants in the factual and free retelling conditions reported more items not previously recalled than participants in the control condition did, while the emotional condition did not show the same advantage. Participants in all three retelling conditions failed to report more previously recalled items as compared with the control condition. Finally, a memory conformity effect was observed for all three retelling conditions. These findings suggest that eyewitnesses' discussions may influence the accuracy of subsequent memory reports, especially when these discussions are focused on emotional details and thoughts.

Yet, most of the time the mechanics of fostering these skills is as challenging as photographing dense fog.  As biologists we constantly reevaluate what we know, how we think about what we know, and how we communicate our knowledge about the living world. These short engaging exercises challenge students to appreciate the central role of abstract thinking and question asking in scientific inquiry.  In the first exercise the classroom is presented with an optical illusion image and challenged to evaluate it using concrete and abstract thinking tools. In a follow up exercise, students are prompted to evaluate the process of making assumptions, asking questions and coming to conclusions using the example of a small popular culture article. Both exercises are used as primers to stimulate discussion emphasizing that abstract thinking and question asking are critical tools in the tool set of 21st century budding biologists.

  5. Emotional stimuli-provoked seizures potentially misdiagnosed as psychogenic non-epileptic attacks: A case of temporal lobe epilepsy with amygdala enlargement

    Directory of Open Access Journals (Sweden)

    Hidetaka Tamune

    Full Text Available The association between emotional stimuli and temporal lobe epilepsy (TLE is largely unknown. Here, we report the case of a depressed, 50-year-old female complaining of episodes of a “spaced out” experience precipitated by emotional stimuli. Psychogenic non-epileptic attacks were suspected. However, video-EEG coupled with emotional stimuli-provoked procedures and MRI findings of amygdala enlargement, led to the diagnosis of left TLE. Accurate diagnosis and explanation improved her subjective depression and seizure frequency. This case demonstrated that emotional stimuli can provoke seizures in TLE and suggested the involvement of the enlarged amygdala and the modulation of emotion-related neural circuits.

  11. Active and Passive Components of Pelvic Floor Muscle Tone in Women with Provoked Vestibulodynia: A Perspective Based on a Review of the Literature.

    2015-11-01

    Pelvic floor muscle (PFM) dysfunctions, especially elevated tone or tension, are suggested to play an important role in the pathophysiology of provoked vestibulodynia (PVD). However, the involvement of the PFMs remains misunderstood as the assessment of muscle tone is complex and requires a thorough understanding of muscle physiology in relation to the characteristics and limitations of current PFM assessment tools. The aim of this review was to describe the structures and mechanisms involved in muscle tone in normally innervated muscle, and to discuss and relate these concepts to the PFM findings in women with PVD. A narrative overview of the literature retrieved from searches of electronic databases and hand searches. Muscle tone in a normally innervated muscle comprises both active (contractile) and passive (viscoelastic) components. Current methods for evaluating PFM tone such as digital palpation, ultrasound imaging, pressure perineometry, dynamometry, and electromyography may evaluate different components. Research findings suggestive of PFM hypertonicity in women with PVD include elevated general PFM tone, changes in viscoelastic properties, and at least in some women, abnormal increases in electrogenic activity. There is a growing body of evidence to support the involvement of PFM hypertonicity in the pathophysiology of PVD. Limitations of the instruments as well as their properties should be considered when evaluating PFM tone in order to obtain better insight into which component of PFM tone is assessed. Future research is required for further investigating the underlying mechanisms of PFM hypertonicity, and studying the specific effects of physiotherapeutic interventions on PFM tone in women with PVD. © 2015 International Society for Sexual Medicine.

  12. Can Fear, Pain, and Muscle Tension Discriminate Vaginismus from Dyspareunia/Provoked Vestibulodynia? Implications for the New DSM-5 Diagnosis of Genito-Pelvic Pain/Penetration Disorder.

    Fear has been suggested as the crucial diagnostic variable that may distinguish vaginismus from dyspareunia. Unfortunately, this has not been systematically investigated. The primary purpose of this study, therefore, was to investigate whether fear as evaluated by subjective, behavioral, and psychophysiological measures could differentiate women with vaginismus from those with dyspareunia/provoked vestibulodynia (PVD) and controls. A second aim was to re-examine whether genital pain and pelvic floor muscle tension differed between vaginismus and dyspareunia/PVD sufferers. Fifty women with vaginismus, 50 women with dyspareunia/PVD, and 43 controls participated in an experimental session comprising a structured interview, pain sensitivity testing, a filmed gynecological examination, and several self-report measures. Results demonstrated that fear and vaginal muscle tension were significantly greater in the vaginismus group as compared to the dyspareunia/PVD and no-pain control groups. Moreover, behavioral measures of fear and vaginal muscle tension were found to discriminate the vaginismus group from the dyspareunia/PVD and no-pain control groups. Genital pain did not differ significantly between the vaginismus and dyspareunia/PVD groups; however, genital pain was found to discriminate both clinical groups from controls. Despite significant statistical differences on fear and vaginal muscle tension variables between women suffering from vaginismus and dyspareunia/PVD, a large overlap was observed between these conditions. These findings may explain the great difficulty health professionals experience in attempting to reliably differentiate vaginismus from dyspareunia/PVD. The implications of these data for the new DSM-5 diagnosis of Genito-Pelvic Pain/Penetration Disorder are discussed.

    In many parts of the world the prevalence of a sedentary lifestyle in combination with high consumption of food has increased, which contributes to increased risk for becoming overweight. Our primary aim was, in an intervention, to examine the influence on health related quality of life (HRQoL) and mood in young normal weight subjects of both sexes, when adopting an obesity provoking behaviour by increasing the energy intake via fast food and simultaneously adopting a sedentary lifestyle. A secondary aim was to follow-up possible long-term effects on HRQoL and mood 6 and 12 months after this short-term intervention. In this prospective study, 18 healthy normal weight subjects (mean age 26±6.6 years), mainly university students were prescribed doubled energy intake, and maximum 5000 steps/day, during 4 weeks. An age and sex matched control group (n=18), who were asked to have unchanged eating habits and physical activity, was recruited. Before and after the intervention questionnaires including Short Form-36, Hospital Anxiety Depression scale, Center of Epidemiological Studies Depression scale, Sense of Coherence and Mastery scale were completed by the subjects in the intervention group and by the controls with 4 weeks interval. Six and 12 months after the intervention the subjects underwent the same procedure as at baseline and the controls completed the same questionnaires. During the intervention, subjects in the intervention group increased their bodyweight and developed markedly lower physical and mental health scores on Short Form-36 as well as depressive symptoms while no changes appeared in the controls. The increase of depressive symptoms was associated with increases of energy intake, body weight and body fat. When followed up, 6 and 12 months after the intervention, physical and mental health had returned completely to baseline values, despite somewhat increased body weight. In conclusion, adopting obesity provoking behaviour for 4 weeks decreases HRQo

    Provoked vestibulodynia (PVD) is a prevalent vulvovaginal pain condition that is associated with sexual and relational consequences for women and their partners. Greater perceived quality of sexual communication has been associated with women's lower pain during intercourse and with couples' better sexual and relational well-being. Whether couples' collaborative (eg, expressing feelings or problem solving) and negative (eg, withdrawing or criticizing) sexual communication patterns (SCPs) are differentially associated with couples' adjustment to PVD is unknown. To examine associations between collaborative and negative SCPs and women's pain and the sexual and relationship adjustment of women with PVD and their partners. Women diagnosed with PVD (N = 87) and their partners completed the Sexual Communication Patterns Questionnaire and measurements of pain (women only), sexual functioning, sexual satisfaction, sexual distress, and relationship satisfaction. (i) Numerical rating scale of pain during intercourse, (ii) Female Sexual Function Index and International Index of Erectile Function, (iii) Global Measure of Sexual Satisfaction, (iv) Female Sexual Distress Scale-Revised, and (v) Couple Satisfaction Index. When women reported greater collaborative SCP, they also reported higher sexual and relationship satisfaction. When women reported greater negative SCP, they reported less relationship satisfaction and had partners who reported greater sexual distress. When partners reported greater collaborative SCP, they also reported higher relationship satisfaction and had female partners who were less sexually distressed. When partners reported higher negative SCP, they also reported less relationship satisfaction. There were no associations between SCP and women's or partners' sexual functioning or women's pain. Collaborative SCP may benefit couples' sexual and relational well-being, whereas negative SCP may impede sexual and relational adjustment to PVD. Findings

    Full Text Available The article is devoted to the importance of selecting the optimal methods of stimulation and motivation for learning. In modern conditions it is very important that the teacher did not give the students ready knowledge, but pointed out the way for the acquisition of knowledge, taught them to gain knowledge. This demands from the philologist the choice of effective forms of working with texts of different types and styles of speech, listening, speaking. In this connection a special attention should be paid to the lessons of speech development. There is a special group of methods to stimulate the development of communicative competence. Among them, the method of discussion, which is increasingly being used during the Russian language lessons. The specificity of using this method in class for teaching Russian as a foreign language, its basic functions (teaching, developing, educating are considered. The key rules for conducting a discussion at the Russian language classes, the main and additional functions-roles of the teacher, the participants, the minute-taker are analyzed. The advantages of the discussion in Russian in comparison to the discussion in the students’ native language are summarized.

    2008-01-01

    The aim of this paper is to stimulate debate about criteria for assessing the scientific contribution of a piece of management research and to guide and encourage researchers in writing papers for publication. The paper also seeks to reduce the number of papers submitted to journals and reviewers which are really unfinished early drafts or which do provide knowledge which could contribute to reducing suffering. The paper draws on and discusses the difference between practical research for a manager and scientific research, as well as the author's experience as researcher, writer, reviewer, editor, research methods course leader and director of research. The discussion highlights that the author should draft the paper under the suggested headings and fulfil criteria of validity, reliability, supported conclusions, generalisability, ensuring that each section follows on from the other, and that the findings are related to previous research. This is the author's personal view about how to carry out and write research to get published, without discussions of other views. The findings in this paper may provoke more debate about management science and the role of this journal. The guidance may help many researchers publish their management research. The paper links practical guidance with discussion of criteria for scientific contribution in a readable way.

    This project of law aims to adapt the electricity and gas sector to the new economical context of opening of the energy markets to competition. It gives to energy companies the internal organization base necessary to warrant a high level of service and a transparent and non-discriminatory access of third parties to transport and distribution networks. These evolutions will allow Electricite de France (EdF) and Gaz de France (GdF) companies to compete on equal terms with their European competitors. It confirms first the prime role of public utility of both companies and then transposes the dispositions of the European directives relative to the organization of EdF and GdF integrated companies. It foresees the creation of two daughter companies for the management of energy transport activities. The project of law foresees also the change of the status of EdF and GdF companies and the reform of the retirement pensions of the personnel. This report presents, first, in a comparative table the articles adopted by the French house of commons and the changes adopted by the Senate. Then, a common text is proposed by the mixed parity commission for the articles that remained under discussion. (J.S.)

  6. Caffeine provokes adverse interactions with 3,4-methylenedioxymethamphetamine (MDMA, ‘ecstasy’) and related psychostimulants: mechanisms and mediators

    Concomitant consumption of caffeine with recreational psychostimulant drugs of abuse can provoke severe acute adverse reactions in addition to longer term consequences. The mechanisms by which caffeine increases the toxicity of psychostimulants include changes in body temperature regulation, cardiotoxicity and lowering of the seizure threshold. Caffeine also influences the stimulatory, discriminative and reinforcing effects of psychostimulant drugs. In this review, we consider our current understanding of such caffeine-related drug interactions, placing a particular emphasis on an adverse interaction between caffeine and the substituted amphetamine, 3,4-methylenedioxymethamphetamine (MDMA, ‘ecstasy’), which has been most recently described and characterized. Co-administration of caffeine profoundly enhances the acute toxicity of MDMA in rats, as manifested by high core body temperature, tachycardia and increased mortality. In addition, co-administration of caffeine enhances the long-term serotonergic neurotoxicity induced by MDMA. Observations to date support an interactive model of drug-induced toxicity comprising MDMA-related enhancement of dopamine release coupled to a caffeine-mediated antagonism of adenosine receptors in addition to inhibition of PDE. These experiments are reviewed together with reports of caffeine-related drug interactions with cocaine, d-amphetamine and ephedrine where similar mechanisms are implicated. Understanding the underlying mechanisms will guide appropriate intervention strategies for the management of severe reactions and potential for increased drug-related toxicity, resulting from concomitant caffeine consumption.

    Full Text Available Objective. Lens osmotic expansion, provoked by overactivated aldose reductase (AR, is the most essential event of sugar cataract. Chloride channel 3 (Clcn3 is a volume-sensitive channel, mainly participating in the regulation of cell fundamental volume, and P-glycoprotein (P-gp acts as its modulator. We aim to study whether P-gp and Clcn3 are involved in lens osmotic expansion of galactosemic cataract. Methods and Results. In vitro, lens epithelial cells (LECs were primarily cultured in gradient galactose medium (10–60 mM, more and more vacuoles appeared in LEC cytoplasm, and mRNA and protein levels of AR, P-gp, and Clcn3 were synchronously upregulated along with the increase of galactose concentration. In vivo, we focused on the early stage of rat galactosemic cataract, amount of vacuoles arose from equatorial area and scattered to the whole anterior capsule of lenses from the 3rd day to the 9th day, and mRNA and protein levels of P-gp and Clcn3 reached the peak around the 9th or 12th day. Conclusion. Galactosemia caused the osmotic stress in lenses; it also markedly leads to the upregulations of AR, P-gp, and Clcn3 in LECs, together resulting in obvious osmotic expansion in vitro and in vivo.

    Provoked vestibulodynia (PVD) is a recurrent idiopathic vulvo-vaginal pain associated with negative sexual and psychological consequences. Facilitative partner responses to pain are currently receiving empirical attention because they are positively associated with women's sexual outcomes. However, the mechanisms through which facilitative responses to pain are associated with these outcomes have not been examined. One potential mechanism is sexual assertiveness, which has been found to be associated with better sexual function and satisfaction in women with PVD. The present study examined whether women's sexual assertiveness mediated the association between women's perception of facilitative partner responses and women's sexual function and satisfaction. Women (N = 140) with PVD symptomatology completed self-reported questionnaires evaluating their perception of their partners' facilitative responses, and their own sexual assertiveness, sexual function, and sexual satisfaction. Dependent measures were sexual function measured by the Female Sexual Function Index and sexual satisfaction assessed by the Global Measure of Sexual Satisfaction Scale. Results indicated that women's higher sexual assertiveness mediated the association between their greater perceived facilitative partner responses and their improved sexual function and satisfaction. Findings suggest a potential mechanism through which partner responses may be associated with women's sexual outcomes.

    To compare sociodemographics, parity and mode of delivery between women diagnosed with vaginismus or localised provoked vestibulodynia (LPV) to women without a diagnosis before first pregnancy. Retrospective, population-based register study. Sweden. All women born in Sweden 1973-83 who gave birth for the first time or remained nulliparous during the years 2001-09. Nationally linked registries were used to identify the study population. Women diagnosed with vaginismus or LPV were compared to all other women. Odds ratios for parity and mode of delivery were calculated using multinominal regression analysis and logistic regression. Parity and mode of delivery. Women with vaginismus/LPV were more likely to be unmarried (P = 0.001), unemployed (P = 0.012), have a higher educational level (P vaginismus/LPV more often delivered by caesarean section (P vaginismus/LPV were more likely to suffer a perineal laceration (adjusted OR 1.87, 95% CI 1.56-2.25). Women with vaginismus/LPV are less likely to give birth and those that do are more likely to deliver by caesarean section and have a caesarean section based upon maternal request. Those women delivering vaginally are more likely to suffer perineal laceration. These findings point to the importance of not only addressing sexual function in women with vaginismus/LPV but reproductive function as well. © 2014 Royal College of Obstetricians and Gynaecologists.

    Provoked vestibulodynia (PVD) is a prevalent women's sexual pain disorder, which is associated with sexual function difficulties. Attachment theory has been used to understand adult sexual outcomes, providing a useful framework for examining sexual adaptation in couples confronted with PVD. Research to date indicates that anxious and avoidant attachment dimensions correlate with worse sexual outcomes in community and clinical samples. The present study examined the association between attachment, pain, sexual function, and sexual satisfaction in a sample of 101 couples in which the women presented with PVD. The actor-partner interdependence model was used in order to investigate both actor and partner effects. This study also examined the role of sexual assertiveness as a mediator of these associations via structural equation modeling. Women completed measures of pain intensity and both members of the couple completed measures of romantic attachment, sexual assertiveness, sexual function, and satisfaction. Results indicated that attachment dimensions did not predict pain intensity. Both anxious and avoidant attachment were associated with lower sexual satisfaction. Only attachment avoidance predicted lower sexual function in women. Partner effects indicated that higher sexual assertiveness in women predicted higher sexual satisfaction in men. Finally, women's sexual assertiveness was found to be a significant mediator of the relationship between their attachment dimensions, sexual function, and satisfaction. Findings highlight the importance of examining how anxious and avoidant attachment may lead to difficulties in sexual assertiveness and to less satisfying sexual interactions in couples where women suffer from PVD.

    Idiopathic pulmonary fibrosis (IPF) poses challenges to understanding its underlying cellular and molecular mechanisms and the development of better therapies. Previous studies suggest a pathophysiological role for neuraminidase 1 (NEU1), an enzyme that removes terminal sialic acid from glycoproteins. We observed increased NEU1 expression in epithelial and endothelial cells, as well as fibroblasts, in the lungs of patients with IPF compared with healthy control lungs. Recombinant adenovirus-mediated gene delivery of NEU1 to cultured primary human cells elicited profound changes in cellular phenotypes. Small airway epithelial cell migration was impaired in wounding assays, whereas, in pulmonary microvascular endothelial cells, NEU1 overexpression strongly impacted global gene expression, increased T cell adhesion to endothelial monolayers, and disrupted endothelial capillary-like tube formation. NEU1 overexpression in fibroblasts provoked increased levels of collagen types I and III, substantial changes in global gene expression, and accelerated degradation of matrix metalloproteinase-14. Intratracheal instillation of NEU1 encoding, but not control adenovirus, induced lymphocyte accumulation in bronchoalveolar lavage samples and lung tissues and elevations of pulmonary transforming growth factor-β and collagen. The lymphocytes were predominantly T cells, with CD8(+) cells exceeding CD4(+) cells by nearly twofold. These combined data indicate that elevated NEU1 expression alters functional activities of distinct lung cell types in vitro and recapitulates lymphocytic infiltration and collagen accumulation in vivo, consistent with mechanisms implicated in lung fibrosis.

    The E6 protein of human papillomavirus type 16 (16E6) is involved in the tumorigenesis of human cervical cells by targeting numerous cellular proteins. We have designed a strategy for neutralizing 16E6 based on the intracellular expression of single-chain Fv antibodies (scFvs) specific to 16E6. Recombinant adenovirus vectors were constructed to allow expression of two 16E6-binding scFvs and one 16E6-non-binding scFv in HPV16-positive and -negative cells. Expression of the scFvs provoked two types of effects: (i) inhibition of proliferation of all cell lines tested, this aspecific toxicity being likely due to the aggregation of unfolded scFvs; and (ii) apoptosis observed only in HPV16-positive cervical cancer cell lines after expression of 16E6-binding scFvs, this specific effect being proportional to the intracellular solubility of the scFvs. These data demonstrate the feasibility of intracellular immunization with anti-16E6 scFvs and highlight the importance of the solubility of the intracellular antibodies

    Full Text Available Mercury (Hg is a highly toxic metal, which can be found in its inorganic form in the environment. This form presents lower liposolubility and lower absorption in the body. In order to elucidate the possible toxicity of inorganic Hg in the hippocampus, we investigated the potential of low doses of mercury chloride (HgCl2 to promote hippocampal dysfunction by employing a chronic exposure model. For this, 56 rats were exposed to HgCl2 (0.375 mg/kg/day via the oral route for 45 days. After the exposure period, the animals were submitted to the cognitive test of fear memory. The hippocampus was collected for the measurement of total Hg levels, analysis of oxidative stress, and evaluation of cytotoxicity, apoptosis, and tissue injury. It was observed that chronic exposure to inorganic Hg promotes an increase in mercury levels in this region and damage to short- and long-term memory. Furthermore, we found that this exposure model provoked oxidative stress, which led to cytotoxicity and cell death by apoptosis, affecting astrocytes and neurons in the hippocampus. Our study demonstrated that inorganic Hg, even with its low liposolubility, is able to produce deleterious effects in the central nervous system, resulting in cognitive impairment and hippocampal damage when administered for a long time at low doses in rats.

  14. Micro-computed tomography derived anisotropy detects tumor provoked deviations in bone in an orthotopic osteosarcoma murine model.

    Full Text Available Radiographic imaging plays a crucial role in the diagnosis of osteosarcoma. Currently, computed-tomography (CT is used to measure tumor-induced osteolysis as a marker for tumor growth by monitoring the bone fractional volume. As most tumors primarily induce osteolysis, lower bone fractional volume has been found to correlate with tumor aggressiveness. However, osteosarcoma is an exception as it induces osteolysis and produces mineralized osteoid simultaneously. Given that competent bone is highly anisotropic (systematic variance in its architectural order renders its physical properties dependent on direction of load and that tumor induced osteolysis and osteogenesis are structurally disorganized relative to competent bone, we hypothesized that μCT-derived measures of anisotropy could be used to qualitatively and quantitatively detect osteosarcoma provoked deviations in bone, both osteolysis and osteogenesis, in vivo. We tested this hypothesis in a murine model of osteosarcoma cells orthotopically injected into the tibia. We demonstrate that, in addition to bone fractional volume, μCT-derived measure of anisotropy is a complete and accurate method to monitor osteosarcoma-induced osteolysis. Additionally, we found that unlike bone fractional volume, anisotropy could also detect tumor-induced osteogenesis. These findings suggest that monitoring tumor-induced changes in the structural property isotropy of the invaded bone may represent a novel means of diagnosing primary and metastatic bone tumors.

    Since radiography yields an image that can be easily related to the tested object, it is superior to many nondestructive testing techniques in revealing the size, shape, and location of certain types of discontinuities. The discussion is limited to a description of the radiographic process, examination of some of the quantitative aspects of radiography, and an outline of some of the new ideas emerging in radiography. The advantages of monoenergetic x-ray radiography and neutron radiography are noted

    Agents building social systems are characterized by complex states, and interactions among individuals can align their opinions. The Axelrod model describes how local interactions can result in emergence of cultural domains. We propose two variants of the Axelrod model where local consensus is reached either by listening and accepting one of neighbors' opinion or two agents discuss their opinion and achieve an agreement with mixed opinions. We show that the local agreement rule affects the character of the transition between the single culture and the multiculture regimes.

    In a crossover study, 5 calves were made acidotic by intermittent intravenous infusion of isotonic hydrochloric acid (HCl) over approximately 24 h. This was followed by rapid (4 h) or slow (24 h) correction of blood pH with isotonic sodium bicarbonate (NaHCO(3)) to determine if rapid correction of acidemia produced paradoxical cerebrospinal fluid (CSF) acidosis. Infusion of HCl produced a marked metabolic acidosis with respiratory compensation. Venous blood pH (mean ± S(x)) was 7.362 ± 0.021 and 7.116 ± 0.032, partial pressure of carbon dioxide (Pco(2), torr) 48.8 ± 1.3 and 34.8 ± 1.4, and bicarbonate (mmol/L), 27.2 ± 1.27 and 11 ± 0.96; CSF pH was 7.344 ± 0.031 and 7.240 ± 0.039, Pco(2) 42.8 ± 2.9 and 34.5 ± 1.4, and bicarbonate 23.5 ± 0.91 and 14.2 ± 1.09 for the period before the infusion of hydrochloric acid and immediately before the start of sodium bicarbonate correction, respectively. In calves treated with rapid infusion of sodium bicarbonate, correction of venous acidemia was significantly more rapid and increases in Pco(2) and bicarbonate in CSF were also more rapid. However, there was no significant difference in CSF pH. After 4 h of correction, CSF pH was 7.238 ± 0.040 and 7.256 ± 0.050, Pco(2) 44.4 ± 2.2 and 34.2 ± 2.1, and bicarbonate 17.8 ± 1.02 and 14.6 ± 1.4 for rapid and slow correction, respectively. Under the conditions of this experiment, rapid correction of acidemia did not provoke paradoxical CSF acidosis.

    Physical therapy (PT) may reduce the pain associated with provoked vestibulodynia (PVD) based on previous findings that pelvic floor muscle dysfunction (PFMD) is associated with PVD symptoms. The goals of this study were: (i) to determine whether women with and without PVD differ on measures of pelvic floor muscle (PFM) behavior; and (ii) to assess the impact of PT treatment for women with PVD on these measures. Eleven women with PVD and 11 control women completed an assessment evaluating PFM behavior using surface electromyography (SEMG) recordings and a digital intravaginal assessment. Women with PVD repeated the assessment after they had undergone eight PT treatment sessions of manual therapy, biofeedback, electrical stimulation, dilator insertions, and home exercises. Superficial and deep PFM SEMG tonic activity and phasic activity in response to a painful pressure stimulus, PFM digital assessment variables (tone, flexibility, relaxation capacity, and strength). At pretreatment, women with PVD had higher tonic SEMG activity in their superficial PFMs compared with the control group, whereas no differences were found in the deep PFMs. Both groups demonstrated contractile responses to the painful pressure stimulus that were significantly higher in the superficial as compared with the deep PFMs, with the responses in the PVD group being higher than those in control women. Women with PVD had higher PFM tone, decreased PFM flexibility and lower PFM relaxation capacity compared with control women. Posttreatment improvements included less PFM responsiveness to pain, less PFM tone, improved vaginal flexibility, and improved PFM relaxation capacity, such that women with PVD no longer differed from controls on these measures. Women with PVD demonstrated altered PFM behavior when compared with controls, providing empirical evidence of PFMD, especially at the superficial layer. A PT rehabilitation program specifically targeting PFMD normalized PFM behavior in women with PVD.

    Alzheimer's disease (AD) is a primary degenerative disease that progressively affects all brain functions, with devastating consequences for the patient, the patient's family and society. Rest regional cerebral blood flow (rCBF) could have a strategic role in differentiating between AD patients and normal controls, but its use for this purpose has a low discriminatory capacity. The purpose of this study was to evaluate whether the diagnostic sensitivity of rCBF single-photon emission computed tomography (SPECT) could be increased by using an episodic memory task provocation, i.e. memory-provoked rCBF-SPECT (MP-SPECT). Eighteen persons (73.2{+-}4.8 years) with mild AD and 18 healthy elderly (69.4{+-}3.9 years) were included in the study. The subjects were injected with{sup 99m}Tc-hexamethylpropylene amine oxime (HMPAO) during memory provocation with faces and names, followed by an rCBF-SPECT study. The rCBF{sup 99m}Tc-HMPAO SPECT images were analysed using statistical parametric mapping (SPM2). Peaks with a false discovery rate corrected value of 0.05 were considered significant. On MP-SPECT, the AD group showed a significant rCBF reduction in the left parietal cortex in comparison with healthy elderly. At rest, no significant group differences were seen. Memory provocation increased the sensitivity of rCBF-SPECT for the detection of AD-related blood flow changes in the brain at the group level. Further studies are needed to evaluate MP-SPECT as a diagnostic tool at the individual level. If a higher sensitivity for AD at the individual level is verified in future studies, a single MP-SPECT study might be sufficient in the clinical setting. (orig.)

    Provoked vestibulodynia (PVD) is a prevalent vulvovaginal pain condition that is triggered primarily during sexual intercourse. PVD adversely impacts women's and their partners' sexual relationship and psychological well-being. Over 80% of women with PVD continue to have intercourse, possibly because of sexual goals that include wanting to pursue desirable outcomes (i.e., approach goals; such as a desire to maintain intimacy) and avoid negative outcomes (i.e., avoidance goals; such as avoiding a partner's disappointment). The aim of this study was to investigate associations between approach and avoidance sexual goals and women's pain, as well as the sexual, relational, and psychological well-being of affected couples. Women with PVD (N = 107) and their partners completed measures of sexual goals, sexual satisfaction, relationship satisfaction, and depression. Women also completed measures of pain during intercourse and sexual functioning. (1) Global Measure of Sexual Satisfaction Scale, (2) Dyadic Adjustment Scale-Revised or the Couple Satisfaction Index, (3) Beck Depression Inventory-II, (4) numerical rating scale of pain during intercourse, and (5) Female Sexual Function Index. When women reported higher avoidance sexual goals, they reported lower sexual and relationship satisfaction, and higher levels of depressive symptoms. In addition, when partners of women reported higher avoidance sexual goals, they reported lower relationship satisfaction. When women reported higher approach sexual goals, they also reported higher sexual and relationship satisfaction. Targeting approach and avoidance sexual goals could enhance the quality and efficacy of psychological couple interventions for women with PVD and their partners. © 2015 International Society for Sexual Medicine.

    Provoked vestibulodynia (PVD) is suspected to be the most frequent cause of vulvodynia in premenopausal women. Based on the onset of PVD relative to the start of sexual experience, PVD can be divided into primary (PVD1) and secondary PVD (PVD2). Studies comparing these PVD subgroups are inconclusive as to whether differences exist in sexual and psychosocial functioning. The aim of this study was to compare the pain, sexual and psychosocial functioning of a large clinical and community-based sample of premenopausal women with PVD1 and PVD2. A total of 269 women (n = 94 PVD1; n = 175 PVD2) completed measures on sociodemographics, pain, sexual, and psychosocial functioning. Dependent variables were the 0-10 pain numerical rating scale, McGill-Melzack Pain Questionnaire, Female Sexual Function Index, Global Measure of Sexual Satisfaction, Beck Depression Inventory-II, Painful Intercourse Self-Efficacy Scale, Pain Catastrophizing Scale, State-Trait Anxiety Inventory Trait Subscale, Ambivalence over Emotional Expression Questionnaire, Hurlbert Index of Sexual Assertiveness, Experiences in Close Relationships Scale--Revised, and Dyadic Adjustment Scale-Revised. At first sexual relationship, women with PVD2 were significantly younger than women with PVD1 (P sexual, psychological, and relational functioning between the PVD subgroups. Nevertheless, on average, both groups were in the clinical range of sexual dysfunction and reported impaired psychological functioning. The findings show that there are no significant differences in the sexual and psychosocial profiles of women with PVD1 and PVD2. Results suggest that similar psychosocial and sex therapy interventions should be offered to both subgroups of PVD. © 2015 International Society for Sexual Medicine.

    Provoked vestibulodynia (PVD) is a highly prevalent vulvovaginal pain condition that results in significant sexual dysfunction, psychological distress, and reduced quality of life. Although some intra-individual psychological factors have been associated with PVD, studies to date have neglected the interpersonal context of this condition. We examined whether partner responses to women's pain experience-from the perspective of both the woman and her partner-are associated with pain intensity, sexual function, and sexual satisfaction. One hundred ninety-one couples (M age for women=33.28, standard deviation [SD]=12.07, M age for men=35.79, SD=12.44) in which the woman suffered from PVD completed the spouse response scale of the Multidimensional Pain Inventory, assessing perceptions of partners' responses to the pain. Women with PVD also completed measures of pain, sexual function, sexual satisfaction, depression, and dyadic adjustment. Dependent measures were women's responses to: (i) a horizontal analog scale assessing the intensity of their pain during intercourse; (ii) the Female Sexual Function Index; and (iii) the Global Measure of Sexual Satisfaction Scale. Controlling for depression, higher solicitous partner responses were associated with higher levels of women's vulvovaginal pain intensity. This association was significant for partner-perceived responses (β=0.29, Psexual function and dyadic adjustment, woman-perceived greater solicitous partner responses (β=0.16, P=0.02) predicted greater sexual satisfaction. Partner-perceived responses did not predict women's sexual satisfaction. Partner responses were not associated with women's sexual function. Findings support the integration of dyadic processes in the conceptualization and treatment of PVD by suggesting that partner responses to pain affect pain intensity and sexual satisfaction in affected women. © 2010 International Society for Sexual Medicine.

    Provoked vestibulodynia (PVD) is a common vulvovaginal pain condition associated with negative psychological and sexual consequences for affected women and their sexual partners. Greater pain acceptance has been found to be associated with better functional and psychological outcomes in individuals with chronic pain, and acceptance-based strategies are being increasingly incorporated into treatment protocols. The present study is a novel investigation of pain acceptance in PVD couples. The aim was to examine the associations between acceptance of vulvovaginal pain and women's pain during intercourse, as well as the psychological and sexual adjustment of both women with PVD and their partners. Sixty-one couples (M(age) for women = 27.95 years, SD = 5.87; M(age) for men = 30.48 years, SD = 6.70) in which the woman was diagnosed with PVD completed the Chronic Pain Acceptance Questionnaire, in reference to women's vulvovaginal pain. Women also rated their pain during intercourse, and couples completed measures of anxiety, depression, sexual function, and sexual satisfaction. Dependent measures were (i) women's self-reported pain during intercourse on a numerical rating scale; (ii) State-Trait Anxiety Inventory trait subscale; (iii) Beck Depression Inventory-II; (iv) Derogatis Interview for Sexual Functioning; and (v) Global Measure of Sexual Satisfaction Scale. Women's greater pain acceptance was associated with their lower self-reported pain during intercourse, controlling for partner's pain acceptance. Greater pain acceptance among women was associated with their own lower anxiety and depression, greater sexual functioning, as well as their own and their partner's greater sexual satisfaction, controlling for the partner's pain acceptance. Additionally, greater pain acceptance among male partners was associated with their own lower depression. Findings suggest that psychological interventions for PVD should target increasing couples' vulvovaginal pain acceptance in

    Zellweger syndrome (ZS) and some peroxisomal diseases are severe inherited disorders mainly characterized by neurological symptoms and cerebellum abnormalities, whose pathogenesis is poorly understood. Biochemically, these diseases are mainly characterized by accumulation of pristanic acid (Prist) and other fatty acids in the brain and other tissues. In this work, we evaluated the in vitro influence of Prist on redox homeostasis by measuring lipid, protein, and DNA damage, as well as the antioxidant defenses and the activities of aconitase and α-ketoglutarate dehydrogenase in cerebellum of 30-day-old rats. The effect of Prist on DNA damage was also evaluated in blood of these animals. Some parameters were also evaluated in cerebellum from neonatal rats and in cerebellum neuronal cultures. Prist significantly increased malondialdehyde (MDA) levels and carbonyl formation and reduced sulfhydryl content and glutathione (GSH) concentrations in cerebellum of young rats. It also caused DNA strand damage in cerebellum and induced a high micronuclei frequency in blood. On the other hand, this fatty acid significantly reduced α-ketoglutarate dehydrogenase and aconitase activities in rat cerebellum. We also verified that Prist-induced increase of MDA levels was totally prevented by melatonin and attenuated by α-tocopherol but not by the nitric oxide synthase inhibitor N(ω)-nitro-L-arginine methyl ester, indicating the involvement of reactive oxygen species in this effect. Cerebellum from neonate rats also showed marked alterations of redox homeostasis, including an increase of MDA levels and a decrease of sulfhydryl content and GSH concentrations elicited by Prist. Finally, Prist provoked an increase of dichlorofluorescein (DCFH) oxidation in cerebellum-cultivated neurons. Our present data indicate that Prist compromises redox homeostasis in rat cerebellum and blood and inhibits critical enzymes of the citric acid cycle that are susceptible to free radical attack. The

    The current approach to women with provoked vestibulodynia (PVD) comprises a multidimensional, multidisciplinary therapeutic protocol. As PVD is considered to be a chronic pain disorder, transcutaneous electrical nerve stimulation (TENS) can be used as an additional therapy for women with otherwise therapy-resistant PVD. The aims of this study were to evaluate whether TENS has a beneficial effect on vulvar pain, sexual functioning, and sexually-related personal distress in women with therapy-resistant PVD and to assess the effect of TENS on the need for vestibulectomy. A longitudinal prospective follow-up study was performed on women with therapy-resistant PVD who received additional domiciliary TENS. Self-report questionnaires and visual analog scales (VASs) were completed at baseline (T1), post-TENS (T2), and follow-up (T3). Vulvar pain, sexual functioning, and sexually-related personal distress were the main outcome measures. Thirty-nine women with therapy-resistant PVD were included. Mean age was 27 ± 5.6 years (range: 19 to 41); mean duration between TENS and T3 follow-up was 10.1 ± 10.7 months (range: 2 to 32). Vulvar pain VAS scores directly post-TENS (median 3.4) and at follow-up (median 3.2) were significantly (P pain and the need for vestibulectomy. The long-term effect was stable. These results not only support our hypothesis that TENS constitutes a feasible and beneficial addition to multidimensional treatment for therapy-resistant PVD, but also the notion that PVD can be considered as a chronic pain syndrome. © 2014 International Society for Sexual Medicine.

    The Illicit nuclear trafficking panel was conducted at the 4th Annual INMM workshop on Reducing the Risk from Radioactive and Nuclear Materials on February 2-3, 2010 in Washington DC. While the workshop occurred prior to the Nuclear Security Summit, April 12-13 2010 in Washington DC, some of the summit issues were raised during the workshop. The Communique of the Washington Nuclear Security Summit stated that 'Nuclear terrorism is one of the most challenging threats to international security, and strong nuclear security measures are the most effective means to prevent terrorists, criminals, or other unauthorized actors from acquiring nuclear materials.' The Illicit Trafficking panel is one means to strengthen nuclear security and cooperation at bilateral, regional and multilateral levels. Such a panel promotes nuclear security culture through technology development, human resources development, education and training. It is a tool which stresses the importance of international cooperation and coordination of assistance to improve efforts to prevent and respond to incidents of illicit nuclear trafficking. Illicit trafficking panel included representatives from US government, an international organization (IAEA), private industry and a non-governmental organization to discuss illicit nuclear trafficking issues. The focus of discussions was on best practices and challenges for addressing illicit nuclear trafficking. Terrorism connection. Workshop discussions pointed out the identification of terrorist connections with several trafficking incidents. Several trafficking cases involved real buyers (as opposed to undercover law enforcement agents) and there have been reports identifying individuals associated with terrorist organizations as prospective plutonium buyers. Some specific groups have been identified that consistently search for materials to buy on the black market, but no criminal groups were identified that specialize in nuclear materials or isotope

    Provoked vestibulodynia (PVD) is the most frequent subtype of vulvodynia. Women report negative consequences of PVD on their sexual and romantic relationships. Researchers have recently highlighted the importance of examining interpersonal factors such as intimacy, and of including both women and their partners in study designs. The aim of this study was to investigate sexual and relationship intimacy as defined by the Interpersonal Process Model of Intimacy and their associations with sexual satisfaction, sexual function, pain self-efficacy, and pain intensity among women with PVD and their partners. Ninety-one heterosexual women (M age = 27.38, SD = 6.04) diagnosed with PVD and their partners (M age = 29.37, SD = 7.79) completed measures of sexual and relationship intimacy, sexual satisfaction, sexual function, pain self-efficacy, and pain intensity. Dependent measures were the (i) Global Measure of Sexual Satisfaction Scale; (ii) Female Sexual Function Index; (iii) Painful Intercourse Self-Efficacy Scale; and (iv) visual analog scale of pain intensity during intercourse. After controlling for women's age, women's greater sexual intimacy (β = 0.49, P sexual satisfaction and higher pain self-efficacy (β = 0.39, P = 0.001), beyond the effects of partners' sexual intimacy. Also, women's greater sexual intimacy (β = 0.24, P = 0.05) and women's greater relationship intimacy (β = 0.54, P = 0.003) were associated with greater women's sexual function, beyond the effects of partners' sexual and relationship intimacy. Women's self-reported sexual and relationship intimacy in the couple relationship may promote higher sexual satisfaction, sexual function, and pain self-efficacy, as well as possibly foster greater sexual well-being among women with PVD. The authors discuss implications for the inclusion of emotional and interpersonal aspects of the couple's dynamic in clinical interventions and future research in PVD. © 2013

    Effective leadership can be defined in many ways and is an essential element of successful organisations; poor leadership can result in problems such as low staff morale, high staff turnover and reduced productivity. Effective leadership behaviours are well documented in the literature and various leadership models have been proposed that illustrate these behaviours. This discussion paper does not focus on any particular model. Instead it considers the 'Leadership Qualities Framework' which was developed specifically for use within the UK National Health Service. This framework draws upon a range of leadership models and as such it gives a broad indication of leadership behaviours. The framework comprises three components - 'personal qualities', 'setting direction' and 'delivering the service'. This paper commences with an argument as to why effective leadership is important in organisations generally, and specifically within healthcare organisations. Various examples of leadership are illustrated from within and outside the NHS in order to demonstrate effective leadership behaviours. The Leadership Qualities Framework is then examined, along with scenarios to illustrate effective leadership behaviours in context (i.e. within a healthcare organisation). Subsequent reflections on the scenarios aim to identify leadership behaviours that are explained within the framework. The final element of this paper draws on [limited] published evidence of where consultant radiographers have demonstrated effective leadership behaviours. In this section the published evidence is examined and reflected upon. At the end of the article we indicate additional reading for those who wish to further develop their theoretical and practical leadership skills

    The metal failure cases discussed by P. Gupton (Monsanto Chem. Co.) at a joint meeting of the American Society of Metals (ASM) and the National Association of Corrosion Engineers Calgary Section (Calgary 1978) include a high-temperature (1775/sup 0/-1800/sup 0/F) failure in an HK 40 outside heater tube in a synthesis gas steam-methane reformer, resulting in two major fissures caused by carbonization and oxide deposits with high carbon and lead contents due to the use of remelt scrap material with high lead content; separation of a support pad from a 30 in. pipeline due to corrosion caused by molybdenum-peroxide action; oxidation of a section of 180/sup 0/ U-bend in a thermal ethylene cracking furnace due to fluxing reaction of a high sodium and calcium feed which collected in the return bed; stress corrosion cracking of an austenitic stainless cracker tube from high temperature and electrolytic attack; and other cases of metal failure caused by weld quality problems, use of contaminated material and inadequate designs, processing, and fabrication.

  1. Emission trading: A discussion paper

    International Nuclear Information System (INIS)

    1992-05-01

    Emission trading is a market-based incentive program designed to control air emissions in which a cap is placed on the total quantity of pollutants allowed to be emitted in an airshed. Appropriate shares of this amount are allocated among participating emission sources, and participants can buy or sell their shares. Advantages of emission trading include its potential to achieve air emission targets at a lower cost than the traditional command and control approach, and its ability to accommodate economic growth without compromising environmental quality. A study was conducted to evaluate the potential use of emission trading programs to achieve emission reduction goals set for nitrogen oxides, volatile organic compounds (VOC), and sulfur oxides. Emission trading programs in the USA are reviewed and a set of factors important for the success of emission trading are identified. Key policy and design issues related to an emission trading program are identified, explained, and discussed. Administrative issues are then analyzed, such as legislative authority, monitoring and enforcement requirements, and trading between jurisdictions. A preliminary assessment of emission trading for control of NOx and VOC in the Lower Fraser Valley indicates that emission trading would be feasible, but legislative authority to implement such a program would have to be introduced

    The Anesthesia Patient Safety Foundation (APSF) was created in 1985. Its founders coined the term "patient safety" in its modern public usage and created the very first patient safety organization, igniting a movement that is now universal in all of health care. Driven by the vision "that no patient shall be harmed by anesthesia," the APSF has worked tirelessly for more than a quarter century to promote safety education and communication through its widely read Newsletter, its programs, and its presentations. The APSF's extensive research grant program has supported a great many projects leading to key safety improvements and, in particular, was central in the development of high-fidelity mannequin simulation as a research and teaching tool. With its pioneering collaboration, the APSF is unique in incorporating the talents and resources of anesthesia professionals of all types, safety scientists, pharmaceutical and equipment manufacturers, regulators, liability insurance companies, and also surgeons. Specific alerts, campaigns, discussions, and projects have targeted a host of safety issues and dangers over the years, starting with minimal intraoperative monitoring in 1986 and all the way up to beach-chair position cerebral perfusion pressure, operating room medication errors, and the extremely popular DVD on operating room fire safety in 2010; the list is long and expansive. The APSF has served as a model and inspiration for subsequent patient safety organizations and has been recognized nationally as having a dramatic positive impact on the safety of anesthesia care. Recognizing that the work is not over, that systems, organizations, and equipment still at times fail, that basic preventable human errors still do sometimes occur, and that "production pressure" in anesthesia practice threatens past safety gains, the APSF is firmly committed and continues to work hard both on established tenets and new patient safety principles.

  3. Long-term exposure to microwave radiation provokes cancer growth: evidences from radars and mobile communication systems.

    In this review we discuss alarming epidemiological and experimental data on possible carcinogenic effects of long term exposure to low intensity microwave (MW) radiation. Recently, a number of reports revealed that under certain conditions the irradiation by low intensity MW can substantially induce cancer progression in humans and in animal models. The carcinogenic effect of MW irradiation is typically manifested after long term (up to 10 years and more) exposure. Nevertheless, even a year of operation of a powerful base transmitting station for mobile communication reportedly resulted in a dramatic increase of cancer incidence among population living nearby. In addition, model studies in rodents unveiled a significant increase in carcinogenesis after 17-24 months of MW exposure both in tumor-prone and intact animals. To that, such metabolic changes, as overproduction of reactive oxygen species, 8-hydroxi-2-deoxyguanosine formation, or ornithine decarboxylase activation under exposure to low intensity MW confirm a stress impact of this factor on living cells. We also address the issue of standards for assessment of biological effects of irradiation. It is now becoming increasingly evident that assessment of biological effects of non-ionizing radiation based on physical (thermal) approach used in recommendations of current regulatory bodies, including the International Commission on Non-Ionizing Radiation Protection (ICNIRP) Guidelines, requires urgent reevaluation. We conclude that recent data strongly point to the need for re-elaboration of the current safety limits for non-ionizing radiation using recently obtained knowledge. We also emphasize that the everyday exposure of both occupational and general public to MW radiation should be regulated based on a precautionary principles which imply maximum restriction of excessive exposure.

    Provoked vestibulodynia (PVD) represent a longstanding pain syndrome that affects large numbers of women worldwide. However, no standardized guidelines for PVD treatment exist. In a cross-sectional pilot study we examined 30 PVD patients on multidimensional parameters including pain, psychological distress and quality of movement, in order to obtain a broader understanding of the somatic and psychological symptoms in PVD, and for the future to develop better interventions. Additionally, we compare the findings to previously published results regarding the same parameters in women with chronic pelvic pain (CPP). Thirty women with PVD recruited from a tertiary care university clinic of gynecology were assessed for demographic data, pain intensity (VAS), psychological distress (GHQ-30 and Tampa scale of Kinesophobia) and quality of movement (standardized Mensendieck test, SMT). Average age of the PVD women was 24.7±3.60 years, 60% of them were in permanent relationships, all were nulliparous, none had been subjected to surgical procedures, 100% were working full or part time and 90% were educated to at least undergraduate level. Mean VAS score was 7.77±1.97 (mean±SD), kinesiophobia 24.4±3.95 and anxiety domain of GHQ-30 9.73±4.06. SMT scores were particularly low for the domains of respiration and gait (less than 50% of optimal scores). PVD women display reduced quality of movement, especially for gait and respiration patterns, increased level of anxiety and high average pain scores. These findings are similar to what we have previously reported in CPP patients. However, in contrast to CPP group, PVD women are on average younger, have higher work participation, higher education level and have not been subjected to surgical procedures. Since PVD women display similar, although somewhat less severe, symptom profile than CPP, we suggest that a multidimensional approach to treatment, such as "somatocognitive therapy" should be investigated in this group as it has

    Full Text Available Background and Aims: Crohn’s Disease (CD, a chronic Inflammatory Bowel Disease, can occur in any part of the gastrointestinal tract, but most frequently in the ileum. Visceral hypersensitivity contributes for development of chronic abdominal pain in this disease. Currently, the understanding of the mechanism underlying hypersensitivity of Crohn’s ileitis has been hindered by a lack of specific animal model. The present study is undertaken to investigate the visceral hypersensitivity provoked by 2,4,6-trinitrobenzene sulfonic (TNBS-induced ileitis rats.Methods: Male Sprague-Dawley rats were anaesthetized and laparotomized for intraileal injection of TNBS (0.6 ml, 80 mg/kg body weight in 30% ethanol, n = 48, an equal volume of 30% Ethanol (n = 24 and Saline (n = 24, respectively. Visceral hypersensitivity was assessed by visceromotor responses (VMR to 20, 40, 60, 80 and 100 mmHg colorectal distension pressure (CRD at day 1, 3, 7, 14, 21 and 28. Immediately after CRD test, the rats were euthanized for collecting the terminal ileal segment for histopathological examinations and ELISA of myleoperoxidase and cytokines (TNF-α, IL-1β, IL-6, and dorsal root ganglia (T11 for determination of calcitonin gene-related peptide by immunohistochemistry, respectively. Results: Among all groups, TNBS-treatment showed transmural inflammation initially at 3 days, reached maximum at 7 days and persisted up to 21 days. The rats with ileitis exhibited (P < 0.05 VMR to CRD at day 7 to day 21. The calcitonin gene-related peptide-immunoreactive positive cells increased (P < 0.05 in dorsal root ganglia at day 7 to 21, which was persistently consistent with visceral hypersensitivity in TNBS-treated rats.Conclusions: TNBS injection into the ileum induced transmural ileitis including granuloma and visceral hypersensitivity. As this model mimics clinical manifestations of CD, it may provide a road map to probe the pathogenesis of gut inflammation and visceral

    The aim of this study was to evaluate the diagnostic value of the MR imaging findings with provoked discography used as the standard for painful lumbar disc derangement. Two hundred patients (412 discs), (age rang: 21-77 year), with chronic low back pain underwent MRI and provoked discography. We evaluated the MRI T2-WI findings such as disc degeneration, high-Intensity zones and endplate abnormalities. Subsequently, provocative discography was independently performed with using MR imaging, and a painful disc was defined when moderate to severe and concordant pain was provoked. We calculated the sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of the MRI findings with using provoked discography as the standard. 400 discs showed abnormal findings such as disc degeneration, HIZ and endplate abnormalities on the T2-WI images. 12 discs showed normal finding. HIZ or endplate abnormalities were always combined with disc degeneration. The prevalence of each findings were disc degeneration (400 discs: 97.1%), HIZ (111 discs: 26.9%), type I endplate abnormalities (34 discs: 8.3%), type II endplate abnormalities (75 discs: 18.2%), the combined findings of HIZ and type I endplate abnormalities (2 discs: 0.5%) and the combined findings of HIZ and type II endplate abnormalities (7 discs: 1.7%). The disc degeneration showed high sensitivity (99.5%) and low specificity (5.0%), so only the NPV (91.7%) was significant, and not the PPV (47.8%). Each findings of HIZ (sensitivity, 36.5%, specificity, 81.4%; PPV, 63.18%; NPV, 59.5%), type I endplate abnormalities (11.0%, 94.1%, 61.8% and 54.8%, respectively), type II endplate abnormalities (19.8%, 83.2%, 50.7% and 54.3%, respectively), the combined findings of HIZ and type I endplate abnormalities (0.5%, 99.6%, 50.0% and 53.4%, respectively) and the combined findings of HIZ and type II endplate abnormalities (26.0%, 99.1%, 71.4% and 53.8%, respectively) show high specificity, but low

    The ability of scientists to apply cloning technology to humans has provoked public discussion and media coverage. The present paper reports on a series of studies examining public attitudes to human cloning in the UK, bringing together a range of quantitative and qualitative methods to address this question. These included a nationally representative survey, an experimental vignette study, focus groups and analyses of media coverage. Overall the research presents a complex picture of attitude to and constructions of human cloning. In all of the analyses, therapeutic cloning was viewed more favourably than reproductive cloning. However, while participants in the focus groups were generally negative about both forms of cloning, and this was also reflected in the media analyses, quantitative results showed more positive responses. In the quantitative research, therapeutic cloning was generally accepted when the benefits of such procedures were clear, and although reproductive cloning was less accepted there was still substantial support. Participants in the focus groups only differentiated between therapeutic and reproductive cloning after the issue of therapeutic cloning was explicitly raised; initially they saw cloning as being reproductive cloning and saw no real benefits. Attitudes were shown to be associated with underlying values associated with scientific progress rather than with age, gender or education, and although there were a few differences in the quantitative data based on religious affiliation, these tended to be small effects. Likewise in the focus groups there was little direct appeal to religion, but the main themes were 'interfering with nature' and the 'status of the embryo', with the latter being used more effectively to try to close down further discussion. In general there was a close correspondence between the media analysis and focus group responses, possibly demonstrating the importance of media as a resource, or that the media reflect

  14. Bioethics and multiculturalism: nuancing the discussion.

    Science.gov (United States)

    Durante, Chris

    2018-02-01

    In his recent analysis of multiculturalism, Tom Beauchamp has argued that those who implement multicultural reasoning in their arguments against common morality theories, such as his own, have failed to understand that multiculturalism is neither a form of moral pluralism nor ethical relativism but is rather a universalistic moral theory in its own right. Beauchamp's position is indeed on the right track in that multiculturalists do not consider themselves ethical relativists. Yet, Beauchamp tends to miss the mark when he argues that multiculturalism is in effect a school of thought that endorses a form of moral universalism that is akin to his own vision of a common morality. As a supporter of multiculturalism, I would like to discuss some aspects of Beauchamp's comments on multiculturalism and clarify what a multicultural account of public bioethics might look like. Ultimately, multiculturalism is purported as a means of managing diversity in the public arena and should not be thought of as endorsing either a version of moral relativism or a universal morality. By simultaneously refraining from the promotion of a comprehensive common moral system while it attempts to avoid a collapse into relativism, multiculturalism can serve as the ethico-political framework in which diverse moralities can be managed and in which opportunities for ethical dialogue, debate and deliberation on the prospects of common bioethical norms are made possible. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

  15. The nuclear power discussion in change. Nuclear controversy has shifted

    2015-01-01

    The public discussion on nuclear energy is not focused on power plant safety anymore. A globally good safety statistic and years of information activity on safety technology provided progress, even though all incidents are still discussed with great dedication. Nevertheless the field of disposal receives more prominence in public discussions since 1976; reprocessing of irradiated fuels and storage of nuclear waste follow the topic of nuclear power plants with temporary shift. During a long preparation time technical and operational know-how was gathered for both fields that is now available for use on large technical scale. For the entire disposal complex exists a comprehensive concept prepared by the federal government, which has to be put into practice together with the industry. The priority assignment for a dialogue with the public is to comprehensively inform on extend and quality of problem solutions and to highlight that even here the safety of the biological-cycle is the guiding principle for all considerations.

  16. Round-table discussion on food irradiation

    International Nuclear Information System (INIS)

    1973-01-01

    The possibilities of using radiation for food preservation as a way of alleviating the food deficiency problem in a large part of the world has been studied for some 20 years. Since the idea was recognized as a viable one, scientists had to develop it along three levels: firstly, the technological problems and economic viability had to be faced; at the same time tests had to be initiated to prove the wholesomeness of the irradiated foodstuffs, and then public acceptance and confidence in the end product had to be established. Work is proceeding along these three lines and in some cases, success has been won on all fronts. In others, it is continuing. As a FLASHBACK to the situation TWO YEARS AGO, we thought it interesting to reprint excerpts from a round-table discussion at which scientists from five countries sat down to discuss the pros and cons of food irradiation. ost at the gathering was Dr. Rocco Basson, Director of Chemistry at Pelindaba, South Africa, and the man responsible for directing radiation processing in that country. With him were Dr. Lapidot, Head of the Radiation and Engineering and Processing Section of the Israel Atomic Energy Commission at Soreq; Dr. Saint-Lebe of the Radioagronomy Service, French Atomic Energy Commission, at Cadarache; Dr. Ulmann, then Director of the Food Irradiation Pilot Plant at Wageningen in Holland; and Mr. Roy Hickman, leader of the International Project in the Field of Irradiation, sponsored by the FAO, IAEA and the OECD Nuclear Energy Agency, centred at Karlsruhe in Germany.

    key points can be highlighted: The main question seems to be: 'What are the elements making the funding system safer?' This can be looked at through different aspects: cost estimate; control of the funding and money collection; control of investment of the money; how to cope with uncertainties (including early shutdown and bankruptcy). The stability of the funding system over the time is a key factor for securing the funding (a good counter-example is the UK story). The decommissioning exercise should start before the plant is in operation; i.e. when a plant is constructed. An important aspect is also the information exchange with people having participated to actual D and D projects. Discussions by session: At the plenary discussions the following items were also recorded: the possibility of having an international body managing decommissioning funds; how far the present generation would need to go today to protect future generations from a virtual risk and how far do these ethical considerations need to be covered by the funds; the use of ethical values in the discussion with the public and the stakeholders; the pros and cons of segregated funds; the management and control of funds

    Full Text Available There is a dearth of research into teaching strategies and learning approaches for units involving sensitive topics that can provoke an emotional response in students. In a business ethics unit, attempts to strike a balance between conceptual knowledge and theory and skills training can be challenging because the unit can involve personal, sensitive or controversial topics. When engaging in deep and meaningful face-to-face discussion, students may unknowingly divulge personal opinions that they later regret or become identified with by other students over time. Value-laden topics may also lead to clashes between students if face-to-face discussions are not managed properly. This paper considers the use of technology in blended learning to provide an optimal learning environment for student discussion on sensitive topics via role-play and simulation in a first-year business ethics unit. The Audience Response System (ARS, online discussion boards and blogs, and wikis are assessed for their suitability in supporting online role-play and simulation. Among these online tools, asynchronous online discussion boards and blogs are the ideal tools for supporting student discussion on sensitive topics in online role-play and simulation.

    The aim of this article is to discuss perspectives on and interpretations of South African history in the early 19th century: in this case, an early history of the Zulu state and a biography of Shaka. Firstly it is an overview of Dan Wylie book, Myth of Iron: Shaka in History. This book, which is a very important voice in the discussion of the beginnings of the Zulu State, is a pretext to look at contemporary so-called revisionist historiography. Far from being averse to revisionist attitu...

    The literatures on public values (PV) and public service motivation (PSM) both address whether public service delivery is driven by something more than self-interest. They have developed separately, although they can benefit from insights developed by the other, and this article discusses...... conceptual and empirical relationships between them. Based on a survey of 501 public managers, we find that PSM and PV are associated empirically, but not in a manner allowing total integration. The conceptual discussion reveals how the two concepts cannot be totally separated, as values can be motivating...

  4. Ethical aspects of radioactive waste management and public information. The Belgian situation

    International Nuclear Information System (INIS)

    Minon, J.P.

    1996-01-01

    Belgium has a well-developed nuclear programme and has elaborated several research and nuclear fuel cycle facilities on its territory since the beginning of the nineteen fifties. About 60 per cent of the electricity produced is of nuclear origin. All these facilities produce waste. In 1980, waste management was entrusted by law to the ONDRAF. The Agency new controls all aspects of waste management and has indicated the direction for final disposal of waste. Both public information and the justification, from an ethical point of view, of the solutions proposed have become an essential topic in radioactive waste management. The situation as it exists today in Belgium is described in this paper. The paper indicates that all decision-making process now pass through an objective information phase, involving the public and the various decision makers. This is intended to provoke discussion and encourage the public to become more active and responsible, and should be based on new ethical concepts. We need to be sure that we put into place for the future, systems based on passive technology, full information and with sufficient financial provision for future needs. (authors)

  5. Relationship between non-genital tender point tenderness and intra-vaginal muscle pain intensity: Ratings in women with provoked vestibulodynia and implications for treatment

    Background Vulvodynia is a chronic vulvar pain disorder and fibromyalgia is a chronic widespread musculoskeletal pain disorder; both of unknown etiology. Association of these conditions is well documented. Intra-vaginal algometer measurement of tenderness to pressure applied to the pelvic floor muscles helps to define vulvodynia associated with musculoskeletal factors. Women with both vulvodynia and fibromyalgia might have increased pelvic muscle pain compared to women with vulvodynia alone, defining the possible link of these two conditions. Objective 1) correlate pain intensity during the non-genital tender point tenderness examination to pain intensity with the vaginal algometer in women with provoked vestibulodynia, 2) determine whether subjects with provoked vestibulodynia and fibromyalgia had higher pain intensity scores with the vaginal algometer than those without fibromyalgia. Study Design Ninety-two subjects referred for vulvar pain were confirmed to have provoked vestibulodynia using the cotton swab test. A diagnosis of fibromyalgia was made if pain was present (Numerical rating scale> 1) in at least 11 sites of the 18-point non-genital tender point tenderness exam. Vaginal pain sensitivity was measured using an intra-vaginal pressure algometer, where 0.1, 0.3, and 0.5 kg/cm2 forces were applied digitally in random assignment by force and location to the right and left iliococcygeus muscle regions and the posterior vaginal wall. Both tender point tenderness and algometer pain intensity were reported on a 0 (no pain) to 10 (worse pain) numeric rating scale. Correlations were computed between the composite pain intensity (total of rating scale from each pressure threshold at specified site) of non-genital and those of iliococcygeus regions and the posterior vaginal wall. Independent t-tests were used to determine differences in iliococcygeus regions and the posterior vaginal algometer pain ratings and presence or absence of fibromyalgia. The significance

    Session 1 provided the opportunity to be informed of the Japanese institutional scene on geologic disposal as well as to acquaint the Japanese dignitaries and workshop participants with the RWMC Regulators' Forum, the challenges we face and the aims of the workshop. A lecture on accomplishments and issues in long-term safety regulation prepared discussions during the workshop. Session 2 - Fundamental Concepts and Evolution of International Guidance: One important point is that the use of language in this subject is not conducive to easy understanding by the public, certainly, and perhaps even by others. We need to consider how it might be made more accessible for the purpose of public involvement and regulatory dialogue. This might open the way to creating a readily comprehensible long-term objective for geological disposal that is consistent with the objectives for protecting society from the potential consequences of other activities with long-lived implications. The goal of the following presentations was to give an overall picture on these questions. Session 3 - Establishing Regulatory Criteria that Account for the Inherent Difficulties Associated with the Long-time Frames for Protection: Even though there have been significant developments in recent years and experience feedback from a number of ongoing geological disposal projects, international guidance remains rather difficult to understand and apply. The recent work from the RWMC-RF on long-term safety criteria for geological for geological disposal also shows that there are important differences between national criteria as well as differences in regulatory approach. It has emerged that we have no common basis for setting criteria as between different NEA countries and that the process of setting criteria is not readily explicable to the general public. Furthermore we are required, for the purposes of the international Joint Convention on the Safe Management of Spent Fuel and Radioactive Waste, to protect

    2005-10-01

    The Internet is an innovative strategy to increase public participation. It is important to include pregnant and parenting teens' perspectives when planning programs to meet their needs. This qualitative study explored online discussions as a strategy to enhance participation by this population. Findings showed that online communication was preferred over face-to-face group discussions. Being anonymous online encouraged open and honest feedback. Participants experienced various forms of social support, however, there was an overall lack of teen involvement online. Strategies to engage adolescents in online discussions and reduce barriers are discussed. Strategies included the use of teen moderators, home computer access, technical support, and engagement in naturally flowing online discussions to meet social support needs. Blending researchers' with teens' needs for social support in an online environment is encouraged. With careful planning and design, online communications can result in mutual benefits for researchers, service providers, and pregnant and parenting adolescents.

  11. Intranasal oxytocin reduces provoked symptoms in female patients with posttraumatic stress disorder despite exerting sympathomimetic and positive chronotropic effects in a randomized controlled trial.

    Posttraumatic stress disorder (PTSD) is a severe psychiatric disease accompanied by neuroendocrine changes such as adrenergic overdrive and hence an elevated cardiovascular morbidity. Current pharmacotherapeutic options for PTSD are less than suboptimal, necessitating the development of PTSD-specific drugs. Although the neuropeptide oxytocin has been repeatedly suggested to be effective in PTSD treatment, there are, to our knowledge, only three studies that have assessed its efficacy on the intensity of PTSD symptoms in PTSD patients - among them one symptom provocation study in male veterans. To evaluate for the first time how oxytocin influences the intensity of provoked PTSD symptoms and, furthermore, cardiac control in female PTSD patients, we assessed their psychic and cardiac response to trauma-script exposure with and without oxytocin pretreatment in a double-blind randomized placebo-controlled study. We used a within-subject design to study 35 female PTSD patients who received oxytocin and placebo in a 2-week interval. Furthermore, we performed a small pilot study to get an idea of the relation of the stress-modulated endogenous oxytocin levels and heart rate - we correlated oxytocin serum levels with the heart rate of 10 healthy individuals before and after exposure to the Trier Social Stress Test (TSST). Intranasal oxytocin treatment was followed by a reduction of provoked total PTSD symptoms, in particular of avoidance, and by an elevation in baseline and maximum heart rate together with a drop in the pre-ejection period, a marker for sympathetic cardiac control. Furthermore, we found a positive correlation between endogenous oxytocin levels and heart rate both before and after TSST challenge in healthy control subjects. This study provides the first evidence that oxytocin treatment reduces the intensity of provoked PTSD symptoms in female PTSD patients. The small size of both samples and the heterogeneity of the patient sample restrict the

    2007-01-01

    This paper discusses issues arising in the measurement of productivity in public services. Compared to measuring productivity in the private sector difficulties arise because the output of public services is often un-priced and because some public services are consumed collectively. A key problem is measuring the full range of outputs and quality improvements delivered by public sector organisations that are valued by society. Without comprehensive measures of output productivity statistics m...

    The "rings" belonging to the genus Ypthima are amongst the most common butterflies in Peninsular Malaysia. However, the species can be difficult to tell apart, with keys relying on minor and often non-discrete ring characters found on the hindwing. Seven species have been reported from Peninsular Malaysia, but this is thought to be an underestimate of diversity. DNA barcodes of 165 individuals, and wing and genital morphology, were examined to reappraise species diversity of this genus in Peninsular Malaysia. DNA barcodes collected during citizen science projects-School Butterfly Project and Peninsular Malaysia Butterfly Count-recently conducted in Peninsular Malaysia were included. The new DNA barcodes formed six groups with different Barcode Index Numbers (BINs) representing four species reported in Peninsular Malaysia. When combined with public DNA barcodes from the Barcode Of Life Datasystems, several taxonomic issues arose. We consider the taxon Y. newboldi, formerly treated as a subspecies of Y. baldus, as a distinct species. DNA barcodes also supported an earlier suggestion that Y. nebulosa is a synonym under Y. horsfieldii humei. Two BINs of the genus Ypthima comprising DNA barcodes collected during citizen science projects did not correspond to any species previously reported in Peninsular Malaysia.

    Full Text Available PURPOSE: To investigate the effects of a new electrocautery device to provoke endovascular venous thermal injury. METHODS: An experimental endovascular electrocautery was placed inside eight ex-vivo bovine saphenous veins models. Each one was divided in eight segments and progressive intensities of electric energy liberated. The macroscopic and microscopic effects were analyzed. RESULTS: Forty bovine saphenous veins segments were studied. The higher the electric energy applied the greater the nuclear picnosis and more intense the cytoplasmatic shrinkage and electrocoagulation effects. CONCLUSION: The experimental endovascular electrocautery device demonstrated to be both capable of inducing the destruction of the intimal layers of the studied vein model and provoke endovascular thermal injury.OBJETIVO: Investigar os efeitos de um modelo experimental de eletrocautério em provocar lesão venosa térmica endovascular. MÉTODOS: O eletrocautério endovascular foi colocado dentro de oito modelos experimentais de veia safena bovina. Cada uma foi dividida em oito segmentos e intensidades progressivas de energia elétrica liberada. Os efeitos macroscópicos e microscópicos foram analisados. RESULTADOS: Foram estudados quarenta segmentos de veia safena bovina. Quanto maior a energia elétrica aplicada pelo eletrocauterizador endovascular maiores foram as alteraçoes de picnose nuclear e mais intensa a retração citoplasmática observada. CONCLUSÃO: O eletrocautério endovascular experimental demonstrou ser capaz de induzir a destruição da camada íntima e provocar lesão térmica endovascular.

    Full Text Available "nVasectomy is one of the extensively used methods of contraception in family planning programs. Antisperm antibodies (ASA develop after vasectomy which can result in auto-immune male infertility. The precise sperm antigens involved in the autoimmune response are still poorly defined, therefore we determined the circulating ASA and identified relevant sperm antigens based on localization of binding sites of ASA to sperm cell antigens, using a rapid, inexpensive and clinically relevant assay in vasectomized men. Results showed that 2.5% of men had ASA at the time of vasectomy, whereas 53.5% of the study population subsequently developed ASA. The numbers of men with circulating ASA increased significantly for the first three months after vasectomy. These antibodies were distinguishable into three groups based on their bindings to different sites of sperm cell antigens including against acrosome and tail in 67.56% and 10.8%, respectively; 21.6% of subjects had antibody to the other parts of the sperm cell antigens. The results of this study are discussed in terms of an autoimmune response against sperm antigens and development of ASA.

    Online discussion has become one of the important strategies for the teacher to teach the students to think critically when conveying their ideas and become more proactive and creative. In this paper, padlet online discussion communication was conducted to examine its effectiveness in enhancing critical thinking. In this study, there are two types of critical thinking: macro and micro critical thinking. A total of 70 Universiti Utara Malaysia Management Foundation Programme students involved in this experimental research design. The students in treatment class are divided to few groups. Every group uses padlet online discussion to discuss the topic given. All the group members discuss and write their ideas in padlet. Ideas that are posted in padlet will be displayed in front of the class so that the entire group in the treatment class could see the given ideas. Paul's (1993) model was used to analyze student's macro and micro critical thinking in padlet online discussion and communication. The finding shows that students who used padlet online discussion backchannel communication have greater macro and micro critical thinking level than students who do not use online discussion.

    [Joint Press Release by the Government of the Republic of Chile and the European Southern Observatory. The text is issued simultaneously in Santiago de Chile (in Spanish) and at the ESO Headquarters in Garching (in English).] Today, Tuesday, 18 April 1995, at the ESO Headquarters in Garching (Germany), Mr. Roberto Cifuentes, Plenipotentiary Ambassador representing the Government of the Republic of Chile, and the Director General of the European Southern Observatory, Professor Riccardo Giacconi, have signed a Supplementary, Interpretative and Amending Agreement to the Convention of 6 November 1963 which governs the relations between Chile and this International Organisation. This Agreement which in practice signifies a widening and strengthening of the cooperative relations between the Organisation and the Chilean scientific community will hereafter be submitted for ratification by the National Congress of the Republic of Chile (the Parliament) and by the ESO Council. According to the Agreement signed today, Chilean astronomers will have privileged access within up to 10 percent observing time on all present and future ESO telescopes in Chile. Moreover, ESO accepts to incorporate into its labour regulations for Chilean personnel concepts like freedom of association and collective bargaining. This signing of the Supplementary, Interpretative and Amending Agreement to the original Convention of 1963 follows after months of constructive dialogue between the parties. It constitutes an important step towards a solution of some of the pending points on the current agenda for discussions between the Government of Chile and ESO. Among the issues still pending, ESO has informed the Government of Chile that respect for its immunities by the Chilean State is of vital importance for the continuation of the construction of the world's largest telescope at Paranal, as well as the continued presence of the Organisation in Chile.

  16. Chinese women's participation in fertility discussions.

    Science.gov (United States)

    Li, L

    1993-01-01

    In an attempt to better understand the process through which the family planning (FP) programs and socioeconomic developments in China affect fertility, women's participation in fertility discussions with their husbands are examined as an intermediate factor in a study based on results of a random survey of 6654 ever-married women of reproductive age from 7 cities and 30 counties of Guangdong. First, it must be noted that Chinese couples do have individual choices (albeit quite limited ones) about their fertility; they can choose to follow or ignore government policy or they can choose to remain childless. The present study has 3 major hypotheses: 1) the more a woman is involved in fertility discussions with her husband, the fewer children she will have; 2) urban women with a higher educational status will be more likely to have such discussions; and 3) women who are contacted individually by FP personnel are more likely to be involved in fertility discussions. After a discussion of data collection and variables (number of living children, education of wife and husband, age at marriage, residence, living with parents, contacted by FP personnel, and discussion with husband), the results are presented in terms of zero-order correlation coefficients indicating their relationships. The bivariate analysis supported the hypotheses. Multiple regression analysis showed that age at marriage, education of wives and husbands, FP contacts, and participation in discussions remain significant fertility determinants (but the correlation between fertility and residence becomes trivial). A further regression model indicated that a woman's educational attainment is the most significant positive indication of their participation in fertility discussions. These results imply that as women's status continues to improve in China and the deeply-rooted patriarchal tradition loses hold, increased gender equity and education will influence a fertility decline. FP personnel could also

    Full Text Available The purpose of this case study was to investigate online discussion as a means to promote critical reflection. The study was conducted during a semester-long graduate course on issues related to literacy instructional strategies. The participants in the study were four reading education candidates. During the semester they participated in online discussion about course readings and reflected on their own teaching experiences. The data sources were the online discussion postings, responses to questionnaires, and interviews. The results suggest that technology-mediated discussion strengthens the learning community, facilitates sharing of professional experience among participants, and enhances teacher reflection. The results also point to the multi-faceted nature of teacher reflection.

    Full Text Available The first translations of Freud's work into Portuguese have presented problems because they were not translated from the German language. More than a hundred years after the beginning of Psychoanalysis, there are still many discussions on Freud's metapsychology and a considerable difficulty in obtaining a consensus on the translation of some concepts. This paper refers back to Freud's concepts of primal repression, repression and suppression. In order to discuss such concepts, we have made use of a film, co-produced by Germans and Argentineans, which is named "The Song in me" (Das Lied in mir, released to the public in 2011 and directed by Florian Micoud Cossen. Through this motion picture, the following of Freud's concepts are analyzed, and the differentiation between them is discussed: suppression and repression, as well as the importance of their precise translation.

    This study examined the hypothesis that computer mediated discussions lead to more extreme decisions than face-to-face (FTF) meeting. Kiesler, Siegel, & McGuire (1984) claimed that computer mediated communication (CMC) tended to be relatively uninhibited, as seen in 'flaming', and that group decisions under CMC using Choice Dilemma Questionnaire tended to be more extreme and riskier than FTF meetings. However, for the same reason, CMC discussions on controversial social issues for which participants initially hold strongly opposing views, might be less likely to reach a consensus, and no polarization should occur. Fifteen 4-member groups discussed a controversial social issue under one of three conditions: FTF, CMC, and partition. After discussion, participants rated their position as a group on a 9-point bipolar scale ranging from strong disagreement to strong agreement. A stronger polarization effect was observed for FTF groups than those where members were separated with partitions. However, no extreme shift from their original, individual positions was found for CMC participants. There results were discussed in terms of 'expertise and status equalization' and 'absence of social context cues' under CMC.

    Directory of Open Access Journals (Sweden)

    Liang Ye

    Full Text Available Tris-(2,3-dibromopropyl isocyanurate (TDBP-TAZTO, an emerging brominated flame retardant, possesses the characteristics of candidate persistent organic pollutants and has displayed toxicity to fish and rodents. TDBP-TAZTO can pass through the blood brain barrier and accumulate in brain. However, the neurotoxicity of TDBP-TAZTO has not yet studied in rodents. We hypothesize that TDBP-TAZTO could induce the neurotoxicity in rat hippocampal neurons. The male adult rats were exposed to TDBP-TAZTO of 5 and 50 mg/kg by gavage, daily for 6 months. TDBP-TAZTO resulted in cognitive impairment and depression-like behaviors, which may be related with TDBP-TAZTO-induced hypothalamic-pituitary-adrenal axis hyperactivation, upregulation of inflammatory and oxidative stress markers, overexpression of pro-apoptotic proteins, downexpression of neurogenesis-related proteins in hippocampus, and hippocampal neurons damage in DG, CA1 and CA3 areas. Our findings suggested that TDBP-TAZTO induces significant hippocampal neurotoxicity, which provokes cognitive impairment and depression-like behaviors in adult rats. Therefore, this research will contribute to evaluate the neurotoxic effects of TDBP-TAZTO in human.

  12. Talking About Sex When Sex Is Painful: Dyadic Sexual Communication Is Associated With Women's Pain, and Couples' Sexual and Psychological Outcomes in Provoked Vestibulodynia.

    2016-11-01

    Provoked vestibulodynia (PVD) is a recurrent vulvovaginal pain condition associated with psychological and sexual consequences for affected women and their partners, including lower quality of dyadic sexual communication compared to pain-free couples. Although greater sexual communication is associated with positive sexual and relational outcomes for both pain-free couples and couples experiencing painful sex, little is known about its role in women's pain and psychological outcomes, especially in a relational context. The present study examined associations between dyadic sexual communication and pain, sexual satisfaction, sexual functioning, and depressive symptoms in a sample of 107 couples in which the woman was diagnosed with PVD via a standardized gynecological assessment. Women completed a measure of pain intensity, and both members of the couple completed measures of their dyadic sexual communication, sexual satisfaction, sexual functioning, and depressive symptoms. Analyses were guided by the actor-partner interdependence model. Women and partners' own perceptions of greater dyadic sexual communication were associated with their own greater sexual satisfaction and sexual functioning, and lower depressive symptoms. Partners' perceptions of greater dyadic sexual communication were also associated with women's lower pain and greater sexual satisfaction. Results point to the importance of dyadic coping conceptualizations for both individual and interpersonal outcomes in PVD. Dyadic sexual communication may be a key treatment target for interventions aimed at improving the pain and psychological and sexual impairments of women with PVD and their partners.

    The work was conducted in the seed analysis laboratory of the department of agriculture and forest sciences of the Universidade Federal de Lavras (Federal University of Lavras. MG), over the period 1999 - 2000. Aiming to evaluate the efficiency of utilization of X - rays in the identification of the several types of internal damages provoked by corn seed drying to high temperatures as well as the effect of those damages upon the physiological quality of stored seeds, lots of the cultivars AG1143 and BR 106 were submitted to drying at the temperature of 50 degrades Celsius. The lots were divided into two categories according to the presence or not of internal damages visible with the naked eye submitted to the X - ray test (for 45 at 25 Kvp of radiation intensity) afterwards. They were separated into three sub lots. CDVCDRX (with visual damages and detected by X - ray) SDVSDRX (without visual damages and with damages detected by X ray). The sub lots were evaluated in their physiological quality by viability and vigor tests. The results showed the efficiency of X ray in detecting internal damages of drying not observed by visual analysis. The vigor of corn seeds with internal drying damages is affected in several manners, depending on the cultivars, evaluation time and sort of damage internal damages of drying detected by the radiographical analysis in spite of not affecting early viability, when they occurs in the two directions horizontal and vertical (Double damage) decrease the vigor of seeds after storage

    Health problems due to heavy metals have become a worldwide concern. Along with its carcinogenicity, arsenic exposure results in impairment of glucose metabolism and insulin secretion as well as altered gene expression and signal transduction. However, the exact mechanism behind the behaviour of arsenic on glucose homeostasis and insulin secretion has not yet been fully understood. Fasting blood sugar and glucose tolerance tests were evaluated. In this study, we demonstrated that arsenic, when acutely administered, induced glucose intolerance in rats, although its chronic oral exposure did not provoke any glucose intolerance or hyperglycemia in rats. The protective activity of N-acetylcysteine, carvedilol and propranolol in male rats exposed to arsenic were also assessed, and N-acetylcysteine, particularly at 40 and 80 mg/kg, prevented the glucose intolerance induced in rats by arsenic. The present study showed that acute, but not chronic, contact with arsenic generates significant changes in the normal glucose tolerance pattern that may be due fundamentally to overproduction of reactive oxygen species and oxidative stress and is preventable by using N-acetylcysteine, a thiol-containing antioxidant.

    An in-depth understanding of the physiological response of bacteria to antibiotic-induced stress is needed for development of new approaches to combatting microbial infections. Fluoroquinolone ciprofloxacin causes phase alterations in Escherichia coli respiration and membrane potential that strongly depend on its concentration. Concentrations lower than the optimal bactericidal concentration (OBC) do not inhibit respiration during the first phase. A dose higher than the OBC provokes immediate SOS-independent inhibition of respiration and growth that can contribute to a decreased SOS response and lowered susceptibility to high concentrations of ciprofloxacin. Cells retain their metabolic activity, membrane potential and accelerated K + uptake and produce low levels of superoxide and H 2 O 2 during the first phase. The time before initiation of the second phase is inversely correlated with the ciprofloxacin concentration. The second phase is SOS-dependent and characterized by respiratory inhibition, membrane depolarization, K + and glutathione leakage and cessation of glucose consumption and may be considered as cell death. atpA, gshA and kefBkefC knockouts, which perturb fluxes of protons and K + , can modify the degree and duration of respiratory inhibition and potassium retention. Loss of K + efflux channels KefB and KefC enhances the susceptibility of E. coli to ciprofloxacin. Copyright © 2016 Institut Pasteur. Published by Elsevier Masson SAS. All rights reserved.

    Provoked vestibulodynia (PVD) is a highly prevalent and taxing female genital pain condition. Despite the intimate nature of this pain and the fact that affective factors such as anxiety have been shown to modulate its manifestations, no study has yet explored the emotional regulation of couples in which the woman suffers from PVD. Ambivalence over emotional expression (AEE) is an emotional regulation variable that quantifies the extent to which a person is comfortable with the way she or he expresses emotions. We examined whether the dyadic AEE of couples in which the woman suffers from PVD was differentially associated with women's pain and couples' psychological, sexual, and relational functioning. Couples (N = 254), in which the woman suffered from PVD, completed the AEE questionnaire. A couple typology of dyadic AEE was created. Dependent measures for both members of the couple were the global measure of sexual satisfaction scale, the Beck depression inventory II, and the revised dyadic adjustment scale. The female sexual function index and the sexual history form were used to assess the sexual function of women and men, respectively. Women also completed the pain rating index of the McGill pain questionnaire. Couples, in which both partners were considered low on AEE, had the highest scores on sexual satisfaction (P = 0.02) and function (P sexual, and relational outcomes. Results indicate that emotional regulation may be important to consider in the assessment and treatment of couples coping with PVD. © 2014 International Society for Sexual Medicine.

    Full Text Available Persistent cardiovascular pathology has been described in hyperthyroid patients even with effective antithyroid treatment. Here, we studied the effect of a well-known antithyroid drug, propylthiouracil (PTU; 20 mg/kg/day, on thyroxine (T4; 500 µg/kg/day-induced increase in blood pressure (BP, cardiac hypertrophy, and altered responses of the contractile myocardium both in vivo and ex vivo after 2 weeks of treatment. Furthermore, the potential recovery through 2 weeks of T4 treatment discontinuation was also investigated. PTU and T4 recovery partially reduced the T4-prompted increase in BP. Alternatively, PTU significantly improved the in vivo left ventricular (LV function with no considerable effects on cardiac hypertrophy or ex vivo right ventricular (RV contractile alterations subsequent to T4 treatment. Conversely, T4 recovery considerably enhanced the T4-provoked cardiac changes both in vivo and ex vivo. Altogether, our data is in agreement with the proposal that hyperthyroidism-induced cardiovascular pathology could persevere even with antithyroid treatments, such as PTU. However, this cannot be generalized and further investigation with different antithyroid treatments should be executed. Moreover, we reveal that recovery following experimental hyperthyroidism could potentially ameliorate cardiac function and decrease the risk for additional cardiac complications, yet, this appears to be model-dependent and should be cautiously construed.

    Full Text Available The objective of this study was to evaluate the effect of organic and conventional grape juices consumption on the behavior of rats and their neuroprotective effect on the activity of brain energy metabolism enzymes in different brain areas of adult rats on the experimental model of hepatic encephalopathy. Male Wistar rats (90-days-old were treated once a day with conventional or organic white grape juice by gavage for 14 days (7 μL/g. On the 15th day the rats received carbon tetrachloride (CCl4 in a single dose of 3.0 mL/kg. Cerebral cortex, hippocampus and cerebellum were dissected to measure the activity of creatine kinase (CK and pyruvate kinase (PK. No changes in feeding behavior were observed after the treatment with the grapes juices. However, there was an increase in grooming behavior in the open field test provoked by both juices. CCl4 inhibited CK activity in cerebral cortex and hippocampus of the rats and CCl4 also reduced PK activity in all brain structures studied. Furthermore, both white grape juices prevented the decrease in the activity of CK and PK. Therefore, we can suggest that organic and conventional white grape juices could restore the activity of enzymes with a central role in brain energy metabolism.

    Childhood maltreatment is robustly associated with adult-onset vulvodynia, a common form of female genito-pelvic pain/penetration disorder. However, little is known about the impact of childhood maltreatment on current sexual, psychological, and relationship adaptation for couples with provoked vestibulodynia (PVD). This study examined the associations between childhood maltreatment and sexual and psychosocial functioning and pain in women with PVD, the most common subtype of vulvodynia, and their partners. A total of 49 couples (M age women = 27.80, SD = 6.05; M age men = 30.04; SD = 6.48) with PVD completed the Childhood Trauma Questionnaire (CTQ), as well as measures of sexual functioning, couple satisfaction, and anxiety. Women also reported on their pain during intercourse. Analyses were guided by the actor-partner interdependence model. Women's higher reports of childhood maltreatment were associated with their lower sexual functioning and higher anxiety. Partners' higher reports of childhood maltreatment were associated with their lower sexual functioning, lower couple satisfaction, and higher anxiety, as well as women's lower couple satisfaction and higher anxiety. Both women's and partners' higher reports of childhood maltreatment were associated with higher affective pain for women. Findings suggest childhood maltreatment experienced by women with PVD and their partners should be considered as part of treatment planning.

    Full Text Available Este trabalho pretende investigar diversos aspectos relacionados aos incentivos governamentais que permitem o abatimento de parte dos gastos das famílias e empresas com assistência à saúde no imposto de renda. Como tais incentivos são deduzidos da renda tributável das pessoas físicas e do lucro tributável das pessoas jurídicas, a arrecadação fiscal do Estado é forçosamente reduzida. Segundo estimativa da Secretaria da Receita Federal, o valor desta renúncia, considerando as despesas com planos de saúde e os desembolsos diretos com assistência médico-hospitalar, girou em torno de R$ 2,8 bilhões em 2005. Em um quadro de subfinanciamento crônico do SUS, esta problemática será discutida à luz da eqüidade do financiamento e dos conflitos de interesse evidenciados no setor saúde.The work discusses the tax incentives with private medical expenses to families and workers in Brazil. The estimate presented by the Federal Fiscal Authority is R$ 2,8 billions in 2005. Initially, a review of concepts about the matter is performed that stressed the lack of consensus in the academic community, about the meaning of tax expenditures. It discussed, also, the relations between this fiscal policy and demand to private health insurance. After, the article presents the results of a documental research concerning political positions of relevant Brazilian social actors found in the 2000's. The discussion pointed to problems of equity and conflicts of interests that are involved with the changes in the rules that discipline these incentives.

  4. Drinking water protection plan; a discussion document

    International Nuclear Information System (INIS)

    2001-01-01

    This draft document outlines the plan of action devised by the Government of British Columbia in an effort to safeguard the purity of the drinking water supply in the province, and invites British Columbians to participate in the elaboration of such a plan. This document concentrates on the assessment of the sources of the water supply (watersheds and aquifers) and on measures to ensure the integrity of the system of water treatment and distribution as the principal components of a comprehensive plan to protect drinking water. The proposed plan involves a multi-barrier approach that will use a combination of measures to ensure that water sources are properly managed and waterworks systems provide safe drinking water. New drinking water planning procedures, more effective local influence and authority, enforceable standards, better access to information and public education programs form the essence of the plan. A series of public meetings are scheduled to provide the public at large with opportunities to comment on the government's plan of action and to offer suggestions for additional measures

    Discussing the theological beliefs that ground Catholic moral principles can make some people uncomfortable, even while others will appreciate it. But these reactions will sometimes be revealed not as the emotions they are, but as objections to the relative independence or dependence of morality on foundational beliefs. In the end, context should dictate whether one displays the theological beliefs that ground Catholic moral principles.

  13. Barriers to public participation

    International Nuclear Information System (INIS)

    Patten, E.

    1986-01-01

    When one talks of public involvement, one immediately thinks of a public hearing. Six problems with the public hearing system are listed and discussed. The constraints involved in the public hearing process are: 1) asking for technical information from general folks; 2) overwhelming the public with complex information; 3) having a format that intimidates the speaker and allows no opportunity for useful dialogue; 4) obtaining a skewed picture of an issue because one hasn't had truly representative comments; 5) citizens having overblown expectations of what public involvement means, and becoming frustrated and cynical when their advice isn't heeded; and 6) convincing the powers that be that a comprehensive program is a wise investment. The second half of this paper lists 21 other forms of public participation, giving a description of each form, its purpose, and brief comments on its advantages

  17. Public acceptance and public relations

    International Nuclear Information System (INIS)

    Tanaka, Yasumasa

    1977-01-01

    A set of problems are discussed, which must be studied before the public relations are dealt with. Firstly, the trade-off between energy and health must be considered. There were several ages in which the consideration on health took preference to the energy requirement in the past. For example, the use of coal in London was prohibited by the King's proclamation in 1,306. Secondly, the selection for the acceptance of atomic power development and utilization is based on the subjective susceptibility psychologically, and cannot be concluded only by the logical reasoning. Thirdly, the strict definition of ''national consensus'' is necessary. That is, whether does it mean pleviscite or mere mood. Fourthly, whether the atomic energy is free from the danger or death biologically or not. Fifthly, is there any method for discriminating the persons who accept atomic power from the persons who do not socially. Although the probability of death caused by atomic accidents is very small (one three hundred millionth a year), many peoples hate atomic power and oppose to the construction of nuclear power plants. Four reasons for this are considered: (1) social diffusion of innovation, (2) nuclear allergy, (3) shortage of the conception of risk-benefit, and (4) heterogeneity of the public. According to the investigation of the relationship between electric power and livelihood, carried out by the policy and science research institute in Tokyo, the highly subjective decision for the acceptance of atomic power is independent of the objective knowledge on atomic power.

  18. Axial nonimaging characteristics of imaging lenses: discussion.

    Science.gov (United States)

    Siew, Ronian

    2016-05-01

    At observation planes away from the image plane, an imaging lens is a nonimaging optic. We examine the variation of axial irradiance with distance in image space and highlight the following little-known observation for discussion: On a per-unit-area basis, the position of the highest concentration in image space is generally not at the focal plane. This characteristic is contrary to common experience, and it offers an additional degree of freedom for the design of detection systems. Additionally, it would also apply to lenses with negative refractive index. The position of peak concentration and its irradiance is dependent upon the location and irradiance of the image. As such, this discussion also includes a close examination of expressions for image irradiance and explains how they are related to irradiance calculations beyond the image plane. This study is restricted to rotationally symmetric refractive imaging systems with incoherent extended Lambertian sources.

    The pros and cons of treating health care as a profit-making business got a lively airing in Boston May 16, when the Harvard School of Public Health's "Second Conference on Strategic Alliances in the Evolving Health Care Market" presented what was billed as a "Socratic panel." The moderator was Charles R. Nesson, J.D., a Harvard Law School professor of 30 years' standing whose knack for guiding lively discussions is well known to viewers of such Public Broadcasting Service series as "The Constitution: That Delicate Balance. "As one panelist mentioned, Boston was an interesting place for this conversation. With a large and eminent medical establishment consisting mostly of traditionally not-for-profit institutions, the metropolis of the only state carried in 1972 by liberal Presidential candidate George McGovern is in one sense a skeptical holdout against the wave of aggressive investment capitalism that has been sweeping the health care industry since the 1994 failure of the Clinton health plan. In another sense, though, managed care-heavy Boston is an innovative crucible of change, just like its dominant HMO, the not-for-profit but merger-minded Harvard Pilgrim Health Care. Both of these facets of Beantown's health care psychology could be discerned in the comments heard during the panel discussion. With the permission of the Harvard School of Public Health--and asking due indulgence for the limitations of tape-recording technology in a room often buzzing with amateur comment--MANAGED CARE is pleased to present selections from the discussion in the hope that they will shed light on the business of health care.

The vendor design review process helps reduce regulatory risks by encouraging early engagement.

  7. Round table discussion during session 1

    International Nuclear Information System (INIS)

    Aebersold, M.

    2004-01-01

    The round table discussions of the first session of the Belgium Workshop addressed the following questions: - Accepting or refusing a person, an institution or a grouping as a legitimate Stakeholder who makes the decision and how? - How are the local partnerships built and organised? - How to obtain community support for the partnership's legitimate decisions/findings? - Experience teaches that no decision is reached solely by formal and legal processes. What role do informal processes play? - How can the informal procedures be accepted? Do they need to be made explicit? Discussion took place after the plenary presentations, at tables grouping Belgian stakeholders and FSC delegates. After the discussion, each table's findings were reported to the plenary. Most of the discussion concerned the local partnerships. Important findings were that the statutes for the partnerships were developed by the partnerships themselves and there were no legally binding rules handed down by the federal level. The partnerships are part of an informal process. A legally binding participation (i.e. within the EIA) will be initiated at a later stage. As the partnerships function outside of the formal legal procedure, they can function in a more flexible way. It was noted that the partnerships make recommendations, but it is not clear what the government will do with these recommendations. It was also argued that the process may cause conflicts between neighboring communities. As in other contexts visited by the FSC, the importance of the right of veto of the community was stressed, although this may cause a conflict between technical suitability and social acceptance. Access of the community to the local partnership is necessary. Finally it was accepted that time is needed to explain the recommendations to the broader community before any decisions are taken.

    Directory of Open Access Journals (Sweden)

    FÉLIX BACIGALUPO

    2007-01-01

    Full Text Available In this concise review we discuss some of the complex edges of the concept of death that arose after the notorious advances in science and medicine over the last 50 years, in which the classical cardio-pulmonary criteria have led to the neurological criteria of death. New complicated questions like the definition of death and the operational criteria for diagnosing it have arisen and we think that they are far from being adequately and satisfactorily solved. A number of important issues -like the reliability and differences between cardio-pulmonary versus brain based criteria of death, if death is an event or a process, the meaning of integration and irreversibility- have not yet received sufficient attention. Here we have approached the death problem from two (biological complex system perspectives: the organism level and the cellular-molecular level. We also discuss issues from a third systemic approach, that is, the entire society, thus involving legal, religious, bioethical and political aspects of death. Our aim is to integrate new perspectives in order to promote further discussion on these critical yet frequently neglected issues

    J. J. Crovisier and J. Honnorez [1988] discuss an article by W. W. Maggs, “Mg May Protect Waste Under Glass” [Maggs, 1988] summarizing work by A. Barkatt (Catholic University, Washington, D.C.), B. P. Glass (University of Delaware, Newark), and S. Alterescu and J. A. O'Keefe (NASA/GSFC, Greenbelt, Md.). We found that seawater is orders of magnitude less corrosive t h an fresh water in attacking tektite glass; traced the protective effect to the presence of magnesium, at a level of about 1.3 g/L in seawater; and suggested that the effect might be useful in protecting nuclear waste glasses from corrosion.Crovisier and Honnorez first make the point that the rate of corrosion of glass is, in principle, a function of the ratio of surface area 5 to the effective volume V. This concept, which is usually discussed in American literature under the name of S/V effects, is discussed by Crovisier and Honnorez in terms of the “permeability of the environment.” These effects have been carefully considered throughout our work (see, for example, Barkatt et al. [19867rsqb;). It turns out that in the sea the effective S/V is so small that the effects referred to by Crovisier and Honnorez can be ignored.

    The Focus Group Discussion (FGD) activity in Mathematical Physics learning has helped students perform the stages of problem solving reflectively. The FGD implementation was conducted to explore the problems and find the right strategy to improve the students' ability to solve the problem accurately which is one of reflective thinking component that has been difficult to improve. The research method used is descriptive qualitative by using single subject response in Physics student. During the FGD process, one student was observed of her reflective thinking development in solving the physics problem. The strategy chosen in the discussion activity was the Cognitive Apprenticeship-Instruction (CA-I) syntax. Based on the results of this study, it is obtained the information that after going through a series of stages of discussion, the students' reflective thinking skills is increased significantly. The scaffolding stage in the CA-I model plays an important role in the process of solving physics problems accurately. Students are able to recognize and formulate problems by describing problem sketches, identifying the variables involved, applying mathematical equations that accord to physics concepts, executing accurately, and applying evaluation by explaining the solution to various contexts.

    Full Text Available A condição de precariedade da população adulta de rua é tratada no âmbito da saúde e das intervenções sociais visando levantar subsídios para a implementação de políticas públicas de saúde para essa população. A conceituação dessa população e sua relação com a exclusão social, a cidade, as economias paralelas, a globalização, as estratégias e os circuitos de sobrevivência desenvolvidos se inserem num contexto de oposição aos mecanismos de apartação social e rompimento dos vínculos familiares, bem como na forma de tratamento institucional. A precariedade e insalubridade das ruas, culminando em exposição e riscos cumulativos requerem intervenções e formas de tratamento orientadas, segundo a sua especificidade, desafiando os conceitos gerais de universalidade, integralidade e eqüidade do Sistema Único de Saúde.The adult homelessness is focused in the scope of the health and of social intervention intending to set up subsidies to the implementation of health public policies to this population. The conceptualization of this population and its relation with social exclusion, the city, the underground economies, globalization, strategies and the survival circuits, are inserted in a context of opposition to the social mechanisms that put them apart from society and breaks the family links. It is also related to institutional practices. The precariousness and unhealthiness from the streets results in a cumulative vulnerability which demands intervention and treatment according to a specific health condition, challenging the general concepts of universal access, integrality and equity of national health policies.

    An increasing proportion of obstetric patients are working women. This widens the world of concern for the obstetrician, who must now become familiar with the consequences of workplace exposures and conditions for both maternal and fetal health. This review briefly explores interactions between chemical and physical hazards on the job and the physiologic changes of pregnancy in order to propose ways in which the obstetrician can intervene on behalf of the individual patient, as well as on the public level. Through discussion of the Pregnancy Discrimination Act, job transfer and modification, disability, breastfeeding, etc., emphasis is placed on the social and policy factors that affect reproductive outcome for the working pregnant woman.

    The reasons why residential customers of public power utilities paid less for power than private sector customers is discussed. Residential customers of investor-owned utilities (IOU's) paid average rates that were 28% above those paid by customers by possibly owned systems during 1990. The reasons for this disparity are that management costs faced by public power systems are below those of private power companies, indicating a greater efficiency of management among public power systems, and customer accounts expenses averaged $33.00 per customer for publicly owned electric utilities compared to $39.00 per customer for private utilities

    Provoked vestibulodynia (PVD) is a prevalent genital pain syndrome that has been assumed to be chronic, with little spontaneous remission. Despite this assumption, there is a dearth of empirical evidence regarding the progression of PVD in a natural setting. Although many treatments are available, there is no single treatment that has demonstrated efficacy above others. The aims of this secondary analysis of a prospective study were to (i) assess changes over a 2-year period in pain, depressive symptoms, and sexual outcomes in women with PVD; and (ii) examine changes based on treatment(s) type. Participants completed questionnaire packages at Time 1 and a follow-up package 2 years later. Visual analog scale of genital pain, Global Measure of Sexual Satisfaction, Female Sexual Function Index, Beck Depression Inventory, Dyadic Adjustment Scale, and sexual intercourse attempts over the past month. Two hundred thirty-nine women with PVD completed both time one and two questionnaires. For the sample as a whole, there was significant improvement over 2 years on pain ratings, sexual satisfaction, sexual function, and depressive symptoms. The most commonly received treatments were physical therapy, sex/psychotherapy, and medical treatment, although 41.0% did not undergo any treatment. Women receiving no treatment also improved significantly on pain ratings. No single treatment type predicted better outcome for any variable except depressive symptoms, in which women who underwent surgery were more likely to improve. These results suggest that PVD may significantly reduce in severity over time. Participants demonstrated clinically significant pain improvement, even when they did not receive treatment. Furthermore, the only single treatment type predicting better outcomes was surgery, and only for depressive symptoms, accounting for only 2.3% of the variance. These data do not demonstrate the superiority of any one treatment and underscore the need to have control groups in

    Provoked vestibulodynia (PVD) is a highly prevalent vulvovaginal pain condition that negatively affects women's emotional, sexual, and relationship well-being. Recent studies have investigated the role of interpersonal variables, including partner responses. We examined whether solicitous and facilitative partner responses were differentially associated with vulvovaginal pain and sexual satisfaction in women with PVD by examining each predictor while controlling for the other. One hundred twenty-one women (M age = 30.60, SD = 10.53) with PVD or self-reported symptoms of PVD completed the solicitous subscale of the spouse response scale of the Multidimensional Pain Inventory, and the facilitative subscale of the Spouse Response Inventory. Participants also completed measures of pain, sexual function, sexual satisfaction, trait anxiety, and avoidance of pain and sexual behaviors (referred to as "avoidance"). Dependent measures were the (i) Pain Rating Index of the McGill Pain Questionnaire with reference to pain during vaginal intercourse and (ii) Global Measure of Sexual Satisfaction Scale. Controlling for trait anxiety and avoidance, higher solicitous partner responses were associated with higher vulvovaginal pain intensity (β = 0.20, P = 0.03), and higher facilitative partner responses were associated with lower pain intensity (β = -0.20, P = 0.04). Controlling for sexual function, trait anxiety, and avoidance, higher facilitative partner responses were associated with higher sexual satisfaction (β = 0.15, P = 0.05). Findings suggest that facilitative partner responses may aid in alleviating vulvovaginal pain and improving sexual satisfaction, whereas solicitous partner responses may contribute to greater pain. © 2012 International Society for Sexual Medicine.

    Provoked vestibulodynia is a female genital pain condition that results in sexual dysfunction and impacts negatively on the couple. Although patients' causal attributions have been linked to worse psychosexual outcomes, no study has documented the male partners' perspective of this distressing problem and its potential influence on their psychosexual adaptation. To identify whether male partners' attributions for vestibulodynia are possible predictors of their dyadic adjustment, sexual functioning, sexual satisfaction, and psychological distress, as well as of women's pain and sexual functioning. Thirty-eight women with vestibulodynia first completed measures of pain intensity and sexual functioning. Male partners responded to mailed questionnaires assessing their own attributions for genital pain as well as their psychological distress, relationship adjustment, sexual functioning, and sexual satisfaction. Women completed the McGill-Melzack Pain Questionnaire (MPQ) and the Female Sexual Function Index (FSFI). Attributions of male partners were measured using an adapted version of the Attributional Style Questionnaire (ASQ)-Partner Version. Men also filled out the Brief Symptom Inventory (BSI), the Dyadic Adjustment Scale (DAS), the Sexual History Form (SHF), and the Global Measure of Sexual Satisfaction (GMSEX). All four negative attribution dimensions and higher levels of women's pain intensity successfully predicted increased psychological distress in male partners. Higher levels of both internal and global attributions were associated with men's poorer dyadic adjustment, whereas global and stable attributions were related to their lower sexual satisfaction. Attributions failed to significantly predict sexual functioning in male partners and women's pain and sexual functioning. Evaluation and treatment of sexual pain problems should involve both partners and should explore the role of negative attributions.

  8. Experimental Evidence that In Vivo Intracerebral Administration of L-2-Hydroxyglutaric Acid to Neonatal Rats Provokes Disruption of Redox Status and Histopathological Abnormalities in the Brain.

    Tissue accumulation of L-2-hydroxyglutaric acid (L-2-HG) is the biochemical hallmark of L-2-hydroxyglutaric aciduria (L-2-HGA), a rare neurometabolic inherited disease characterized by neurological symptoms and brain white matter abnormalities whose pathogenesis is not yet well established. L-2-HG was intracerebrally administered to rat pups at postnatal day 1 (P1) to induce a rise of L-2-HG levels in the central nervous system (CNS). Thereafter, we investigated whether L-2-HG in vivo administration could disturb redox homeostasis and induce brain histopathological alterations in the cerebral cortex and striatum of neonatal rats. L-2-HG markedly induced the generation of reactive oxygen species (increase of 2',7'-dichloroflurescein-DCFH-oxidation), lipid peroxidation (increase of malondialdehyde concentrations), and protein oxidation (increase of carbonyl formation and decrease of sulfhydryl content), besides decreasing the antioxidant defenses (reduced glutathione-GSH) and sulfhydryl content in the cerebral cortex. Alterations of the activities of various antioxidant enzymes were also observed in the cerebral cortex and striatum following L-2-HG administration. Furthermore, L-2-HG-induced lipid peroxidation and GSH decrease in the cerebral cortex were prevented by the antioxidant melatonin and by the classical antagonist of NMDA glutamate receptor MK-801, suggesting the involvement of reactive species and of overstimulation of NMDA receptor in these effects. Finally, L-2-HG provoked significant vacuolation and edema particularly in the cerebral cortex with less intense alterations in the striatum that were possibly associated with the unbalanced redox homeostasis caused by this metabolite. Taken together, it is presumed that these pathomechanisms may underlie the neurological symptoms and brain abnormalities observed in the affected patients.

    Age-associated changes in different bandwidths of the human electroencephalographic (EEG) spectrum are well documented, but their functional significance is poorly understood. This spectrum seems to represent summation of simultaneous influences of several sleep-wake regulatory processes. Scoring of its orthogonal (uncorrelated) principal components can help in separation of the brain signatures of these processes. In particular, the opposite age-associated changes were documented for scores on the two largest (1st and 2nd) principal components of the sleep EEG spectrum. A decrease of the first score and an increase of the second score can reflect, respectively, the weakening of the sleep drive and disinhibition of the opposing wake drive with age. In order to support the suggestion of age-associated disinhibition of the wake drive from the antagonistic influence of the sleep drive, we analyzed principal component scores of the resting EEG spectra obtained in sleep deprivation experiments with 81 healthy young adults aged between 19 and 26 and 40 healthy older adults aged between 45 and 66 years. At the second day of the sleep deprivation experiments, frontal scores on the 1st principal component of the EEG spectrum demonstrated an age-associated reduction of response to eyes closed relaxation. Scores on the 2nd principal component were either initially increased during wakefulness or less responsive to such sleep-provoking conditions (frontal and occipital scores, respectively). These results are in line with the suggestion of disinhibition of the wake drive with age. They provide an explanation of why older adults are less vulnerable to sleep deprivation than young adults.

    Projects in public-private partnerships, such as the Innovative Medicines Initiative (IMI), produce data services and platforms (digital assets) to help support the use of medical research data and IT tools. Maintaining these assets beyond the funding period of a project can be a challenge. The reason for that is the need to develop a business model that integrates the perspectives of all different stakeholders involved in the project, and these digital assets might not necessarily be addressing a problem for which there is an addressable market of paying customers. In this manuscript, we review four IMI projects and the digital assets they produced as a means of illustrating the challenges in making digital assets sustainable and the lessons learned. To progress digital assets beyond proof-of-concept into widely adopted tools, there is a need for continuation of multi-stakeholder support tailored to these assets. This would be best done by implementing a structure similar to the accelerators that are in place to help transform startup businesses into growing and thriving businesses. The aim of this article is to highlight the risk of digital asset loss and to provoke discussion on the concept of developing an "accelerator" for digital assets from public-private partnership research projects to increase the chance that digital assets will be sustained and continue to add value long after a project has ended.

    The concept of risk, the methods for assessing risk and the acceptability of risk are discussed. The emphasis was laid on the three components for complete description of a risk: scenario, probability and consequence of an event. The disadvantages of the concept and presentation of risk used in some risk analysis were pointed out. The paper emphasized that it is necessary to explicitly consider the multi-dimensionality of risk in the assessment and management of risk. Several important factors influencing the acceptability of risk and the methodology for evaluating the acceptability of risk were also described

    The experts' discussion on reactor safety research deals with risk analysis, political realization, man and technics, as well as with the international state of affairs. Inspite of a controversy on individual issues and on the proportion of governmental and industrial involvment in reactor safety research, the continuation and intensification of corresponding research work is said to be necessary. Several participants demanded to consider possible 'conventional accidents' as well as a stronger financial commitment by the industry in this sector. The ratio 'man and technics' being an interface decisive for the proper functioning or failure of complex technical systems requires even more research work to be done. (GL) [de

    This executive summary addresses the activities associated with the National Transuranic (TRU) Program managed by the Carlsbad Area Office (CAO). The CAO programmatically reports to the Assistant Secretary for Environmental Management and receives administrative support through the Albuquerque Operations Office. The mission of the Carlsbad Area Office (CAO) is to protect human health and the environment by opening and operating the Waste Isolation Pilot Plant for site disposal of TRU waste and by establishing an effective system for management of TRU waste from generation to disposal. It includes personnel assigned to the CAO, the Waste Isolation Pilot Plant (WIPP) site operations, and other activities associated with the National TRU Program. The CAO develops and directs implementation of the program, while the DOE Headquarters establishes policy and guidelines. The CAO assesses compliance with the program guidance, as well as the commonality of activities and assumptions among all the sites. Since the development of the February 28, 1997, database used to develop this Discussion Draft, the opening of the WIPP facility for receipt of Contact Handled waste has been delayed from November 1997 to May 1998. This slippage is significant enough to require a change in the milestones and volumes included in the documents to be reviewed by our stakeholders. Changes have been incorporated into this Discussion Draft and its supporting Project Baseline Summaries (PBSs)

  18. Brain plasticity, memory, and aging: a discussion

    1977-12-01

    It is generally assumed that memory faculties decline with age. A discussion of the relationship of memory and aging and the possibility of retarding the potential decline is hampered by the fact that no satisfactory explanation of memory is available in either molecular or anatomical terms. However, this lack of description of memory does not mean that there is a lack of suggested mechanisms for long-term memory storage. Present theories of memory usually include first, neurophysiological or electrical events, followed by a series of chemical events which ultimately lead to long-lasting anatomical changes in the brain. Evidence is increasing for the biochemical and anatomical plasticity of the nervous system and its importance in the normal functioning of the brain. Modification of this plasticity may be an important factor in senescence. This discussion reports experiments which indicate that protein synthesis and anatomical changes may be involved in long-term memory storage. Environmental influences can produce quantitative differences in brain anatomy and in behavior. In experimental animals, enriched environments lead to more complex anatomical patterns than do colony or impoverished environments. This raises fundamental questions about the adequacy of the isolated animal which is frequently being used as a model for aging research. A more important applied question is the role of social and intellectual stimulation in influencing aging of the human brain.

    It is increasingly common in physics classes for students to work together to solve problems and perform laboratory experiments. When students work together, they need to negotiate the roles and decision making within the group. We examine how a large group of students negotiates authority as part of their two week summer College Readiness Program at Rochester Institute of Technology. The program is designed to develop metacognitive skills in first generation and Deaf and hard-of-hearing (DHH) STEM undergraduates through cooperative group work, laboratory experimentation, and explicit reflection exercises. On the first full day of the program, the students collaboratively developed a sign for the word ``metacognition'' for which there is not a sign in American Sign Language. This presentation will focus on three aspects of the ensuing discussion: (1) how the instructor communicated expectations about decision making; (2) how the instructor promoted student-driven decision making rather than instructor-driven policy; and (3) one student's shifts in decision making behavior. We conclude by discussing implications of this research for activity-based physics instruction.

    Peer relationships, particularly friendships, have been theorized to contribute to how children and adolescents think about social and moral issues. The current study examined how young adolescent best friends (191 dyads; 53.4% female) reason together about multifaceted social dilemmas and how their reasoning is related to friendship quality. Mutually-recognized friendship dyads were videotaped discussing dilemmas entailing moral, social-conventional and prudential/pragmatic issues. Both dyad members completed a self-report measure of friendship quality. Dyadic data analyses guided by the Actor-Partner Interdependence Model indicated that adolescent and friend's reports of friendship qualities were related to the forms of reasoning used during discussion. Friends who both reported that they could resolve conflicts in a constructive way were more likely to use moral reasoning than friends who reported that their conflict resolution was poor or disagreed on the quality of their conflict resolution. The findings provide evidence for the important role that friendship interaction may play in adolescents’ social and moral development. PMID:23666555

    The author introduces a special section of Psychological Bulletin devoted to the study of disgust. After discussing conflicts between its supposed role as a basic emotion and its more recently understood involvement in responding to moral transgressions, the author summarizes 3 articles contained in the special section. Widen and Russell (2013) present a developmental account of disgust highlighting the ages at which children experience, express, understand, verbalize, and recognize disgust. The article shows that disgust is present early but that recognition of disgust in others is considerably delayed. Chapman and Anderson (2013) review evidence pertaining to the question of whether genuine disgust is elicited by moral transgressions. Their review covers data from self-report, brain imaging, facial behavior, and implicit measures gathered from both experimental and correlational studies. They conclude that moral transgressions elicit genuine disgust. Russell and Giner-Sorolla (2013) ask what types of moral transgressions are most likely to elicit pure disgust. They find that moral transgressions involving body violations are more likely than others to elicit such disgust. Moreover, they suggest that disgust elicited by body violations is likely to be more resistant to modification by context, situation, and efforts at rationalization. Taken together, the reviews support the view that rudiments of disgust to physical objects are present early in life but later become adapted to social influence and new moral purposes. Social implications are discussed. © 2013 American Psychological Association

    1991-01-01

    A panel discussion on the radiotracer development process opened with a question regarding the role of toxicological studies in the process of obtaining a physician-sponsored Investigational New Drug (IND) for a new radiopharmaceutical. Panel members were uniformly supportive of new radiotracer development, expressing their opinions that the regulatory hurdles were there but could be overcome. Several institutions are actively working with regulatory agencies to determine just what toxicology data are relevant to new radiopharmaceutical development in the PET field. The FDA is beginning to understand that the pharmacology of PET tracer doses may be completely different from what is usually important in drug trials. The second part of the panel discussion centered on the role, if any, of the pharmaceutical companies in new radiotracer development. It was pointed out that what the radiochemist is looking for in a radiopharmaceutical is different from what these companies are searching for in a therapeutic drug. Panel and audience members responded to the question: What would a pharmaceutical company gain from collaboration with radiopharmaceutical research laboratories? Several examples were given such as providing crucial data from humans rather than animals; determining individualized drug doses to maximize the therapeutic index of a new drug regimen; and replacing the large amounts of time and money currently invested by drug companies in the radiolabeling and evaluation of metabolites of new drugs

    The politics of oil pipelines have become increasingly salient in American politics in recent years. In particular, debates about economic benefits, energy security and environmental impact have been provoked by the proposed Keystone XL pipeline expansion intended to take bitumen from northern Alberta in Canada to refineries on the Gulf Coast in Texas. Drawing on data from recent surveys conducted by the Pew Research Center, this article asks a series of questions. What levels of support for (and opposition to) the pipeline exist among the American public? What are the roles of political factors (such as party identification and ideology), economic attitudes, environmental attitudes and proximity to the proposed pipeline route in shaping attitudes toward the pipeline? And how do political factors and proximity to the pipeline interact? We find that partisanship and ideology drive attitudes toward the Keystone XL pipeline, and that the effect of ideology is attenuated by proximity to the proposed route. The policy implications of these findings for energy infrastructure siting controversies are discussed. -- Highlights: •Americans are divided on the Keystone XL energy pipeline. •Attitudes toward Keystone XL are driven by political party identification and ideology. •Attitudes toward the pipeline are also shaped by attitudes toward the economy and global warming. •The effect of proximity on attitudes toward Keystone XL is non-linear. •Spatial proximity to the pipeline attenuates the effect of ideology

    Full Text Available This paper argues that the increasing use of internet and its social media in Indonesia’s diplomacy has inevitably promoted the role of the state in enhancing public diplomacy (PD. On the one hand, Indonesia’s PD had found new ‘vehicles’ to reach society through various internet-based applications. These tendencies are in line with the serious effort of involving people or non-state actors in diplomacy. On the other hands, Indonesia’s PD has also had to deal with several problems and threats of the internet’s use, which have inevitably provoked governments’ authority in order to manage and coordinate responses and policies. This paper seeks to discuss to what extent the Ministry of Foreign Affairs (MOFAor Kementerian Luar Negeri (Kemlu has responded to manage the growing use of internet in PD for achieving national interest.Therefore, an analysis on the way the MOFA has maximized social media and digital diplomacy platforms and integrated them into Indonesia’s diplomatic practices is of importance.

    This report assesses current public domain cyber security practices with respect to cyber indications and warnings. It describes cybersecurity industry and government activities, including cybersecurity tools, methods, practices, and international and government-wide initiatives known to be impacting current practice. Of particular note are the U.S. Government's Trusted Internet Connection (TIC) and 'Einstein' programs, which are serving to consolidate the Government's internet access points and to provide some capability to monitor and mitigate cyber attacks. Next, this report catalogs activities undertaken by various industry and government entities. In addition, it assesses the benchmarks of HPC capability and other HPC attributes that may lend themselves to assist in the solution of this problem. This report draws few conclusions, as it is intended to assess current practice in preparation for future work, however, no explicit references to HPC usage for the purpose of analyzing cyber infrastructure in near-real-time were found in the current practice. This report and a related SAND2010-4766 National Cyber Defense High Performance Computing and Analysis: Concepts, Planning and Roadmap report are intended to provoke discussion throughout a broad audience about developing a cohesive HPC centric solution to wide-area cybersecurity problems.

  7. Fragmentation and Polarization of the Public Sphere in the 2000s: Evidence from Italy and Russia

    Full Text Available After the Arab spring, direct linkage between growth of technological hybridization of media systems and political online-to-offline protest spill-overs seemed evident, at least in several aspects, as ‘twitter revolutions’ showed organizational potential of the mediated communication of today. But in de-facto politically transitional countries hybridization of media systems is capable of performing not just organizational but also ‘cultivational’ roles in terms of creating communicative milieus where protest consensus is formed, provoking spill-overs from expressing political opinions online to street protest.The two cases of Italy and Russia are discussed in terms of their nonfinished process of transition to democracy and the media’s role within the recent political process. In the two cases, media-political conditions have called into being major cleavages in national deliberative space that may be conceptualized like formation of nation-wide public counter-spheres based upon alternative agenda and new means of communication. The structure and features of these counter-spheres are reconstructed; to check whether regional specifics are involved into the formation of this growing social gap, quantitative analysis of regional online news media (website menus is conducted. Several indicators for spotting the formation of counter-spheres and criteria for further estimation of democratic quality of such counter-spheres are suggested.

    Mann, J.M.

    1983-01-01

    Public perceptions of risk will probably always be unsatisfying to a scientist. Public perceptions are formed by the actions of institutions which have goals other than formation of an informed public opinion, such as the schools, the media, business and the government. In this environment, it seems unrealistic to expect public opinion to reflect scientific realities. The talk will focus on the media as an opinion-former and will discuss several non-nuclear issues as illustrations: plague in New Mexico, Toxic Shock Syndrome, and Injuries as a Public Health Problem. Ultimately however, we are confronted with two wonderfully complex matters: can risk be adequately expressed or measured in universally comprehensible or broadly acceptable terms; and the mysterious movements of the public and collective mind

    The evaluation of the impact of public policies to improve the performance of the small business sector has provoked a great deal of debate and research activity in recent years. The debate can be categorised in two broad ways. First, it can be seen in terms of the actual impact measures and schemes of small business support may have in terms of enhanced growth performance of SMEs. Second, the search for appropriate evaluation methodologies which reflect the range of problems associated with ...

    This article reports an open discussion that took place during the Keenan Symposium "Meeting the Entropy Challenge" (held in Cambridge, Massachusetts, on October 5, 2007) following the short presentations—each reported as a separate article in the present volume—by Joseph Smith Jr., Howard Butler, Andrew Foley, Kimberly Hamad-Schifferli, Bernhardt Trout, Jeffery Lewins, Enzo Zanchini, and Michael von Spakovsky. All panelists and the audience were asked to address the following questions • Why is the second law taught in so many different ways? Why so many textbooks on thermodynamics? Why so many schools of thought? • Some say that thermodynamics is limited to equilibrium, others that it extends to nonequilibrium. How is entropy defined for nonequilibrium states?

  13. An uplifting discussion of T-duality

    Harvey, Jeffrey A.; Moore, Gregory W.

    2018-05-01

    It is well known that string theory has a T-duality symmetry relating circle compactifications of large and small radius. This symmetry plays a foundational role in string theory. We note here that while T-duality is order two acting on the moduli space of compactifications, it is order four in its action on the conformal field theory state space. More generally, involutions in the Weyl group W ( G) which act at points of enhanced G symmetry have canonical lifts to order four elements of G, a phenomenon first investigated by J. Tits in the mathematical literature on Lie groups and generalized here to conformal field theory. This simple fact has a number of interesting consequences. One consequence is a reevaluation of a mod two condition appearing in asymmetric orbifold constructions. We also briefly discuss the implications for the idea that T-duality and its generalizations should be thought of as discrete gauge symmetries in spacetime.

    2014-07-01

    Full Text Available Open Access (OA, like any other model or strategy for the dissemination of knowledge, carries with it clear benefits as well as costs and downsides. These vary depending on the OA strategy in question, and in order for OA to bring maximum benefit to the world of scholarship, its costs and benefits need be examined carefully and dispassionately so that the former can be maximized and the latter minimized. Unfortunately, the OA advocacy community tends to resist all attempts to examine OA in this way, to the point that those who approach OA in a spirit of critical analysis (rather than celebration and evangelism are attacked and punished. This article describes the problem, provides examples of it, and proposes strategies for promoting a more rigorous and analytical discussion of OA.

    Fourty public dams are managed on a real-time basis by the Centre d'expertise hydrique du Quebec (CEHQ). This presentation described the public dams owned by the CEHQ and discussed the public safety measures at the dams. The dams serve various purposes, including protection against floods; industrial or drinking water supply; resort or recreational activities; hydroelectric development; and wildlife conservation. Trigger events were also discussed, such as the complaint at Rapides-des-Cedres dam and deaths that occurred in 2004 when water from a dam was released without warning. Several photographs were presented to illustrate that people were unaware of the danger. Initiatives aimed at raising awareness and studying public safety issues were discussed. A pilot project was launched and a permanent committee was created to evaluate all aspects of public safety at the dams owned by CEHQ. The first tasks of the committee were to establish requirements for waterway safety barriers, both upstream and downstream, for all public dams; to establish requirements for safety signage for all public dams; and to develop criteria to decide on safety signage at each dam. figs.

    Full Text Available Before 9/11 WTC was an international landmark. The definition of the two high-rise buildings identity, their tourist, social, visual and economic significance, disappeared with the destruction of their materiality. As a result, the contemplative visual and unwritten discourse of the Lower Manhattan disappeared together with the architectural, urban, technological essence and also with the philosophy of stability and equilibrium of a prosperous society. At the social-mental level this event triggers a crisis in personal and collective consciences (of the American Nation but also of the Nations, and a crisis of humanity. The architectural - urban and ideas competition organized to select the best urban-social-architectural concept proved to be a difficult task. Not only it had to “fill” a particular place on earth, but it also needed to configure a philosophy of place that would ‘heal” the wounds of the local and international communities, namely the lack of security and prosperity brought on by a no longer hidden technology of aggression bringing cities and communities under threats never experienced before at times of peace. In its first part the article discusses the competition, proposals and the finalized urban project. The particular challenges related to the selection of design in the case of WTC are doubled by a certain complexity related to the institutional arrangements common to most large urban development projects. It is also clear that there is interdependency between the project governance and the project results. These aspects are discussed in the second part of the article.

  19. Potential for nuclear terrorism: a discussion

    Because there has never been an incident of nuclear terrorism, the author is reduced to informed speculation. The past cannot be used to extrapolate into the future. For terrorists as for nations, the domain of nuclear attack represents are unprecedented quantum leap, one that groups think carefully about. Terrorists will consider many factors, including the public climate, because they are not psychotics operating in a vacuum (though groups may include psychotic individuals). Rather, they are people involved in a reciprocal political and psychological relationship with the rest of the world. In reaching some assessment of the potential for nuclear terrorism, there is an immense number of variables to deal with, beginning with the many types of terrorists and terrorism, including nuclear. They can, however, look at individual terrorist groups - a their compositions, capabilities, motivations, and modus operandi - and reach some conclusions. The author first looks at the possible forms nuclear terrorism might take and at the severity of the consequences. A strict distinction must be made between nuclear terrorism where nuclear things are the means (for example, a nuclear device) and nuclear terrorism where nuclear things are the target (for example, nuclear power stations), or where they are both such as a nuclear weapon thrown at a nuclear power station. 2 tables

  20. Discussion point: should governments buy drug patents?

    del Llano, Juan

    2007-06-01

    Between just 1995 and 2003, the number of new chemical entities fell from 45 to 25, while the costs increased by two and a half times in the same period. Firms in the USA accounted for more than half of biotech drugs from 1982 to 2003. European firms are losing competitiveness. In this hostile environment for investment in pharmaceutical R&D, providing quick access to market for real innovations is the main challenge for regulatory agencies. More initiatives, more entrepreneurial spirit and easier work regulation are needed to facilitate the growth of firms in this field, especially in emerging economies like the Spanish. A new open source model proposes the use of pre-competitive public platforms formed by young and qualified human capital carrying out research in areas not sufficiently attractive for private initiatives, followed by the introduction of pharmaceutical companies to carry out the clinical research. The last step would be fast and effective approval by assessment agencies. Governments should, therefore, facilitate the regulation of socially effective innovations, bringing in manufacturers to take part in the post-clinical trial period after entering the market. The gathering of incentives between regulatory agencies and pharmaceutical industry must be approached through innovation and authorization stimulating systems.

    Full text of publication follows: University nuclear science and engineering programs in the United States currently operate in a business climate that involves serious and dramatic change. The number of degree-granting nuclear engineering programs within the nation's universities has declined over the past two decades to approximately 25. More than two-thirds of the faculty in these programs are 45 yr or older. Recruiting and retaining the best faculty and students continue to be vital to the continued success and existence of these programs. Many universities are also experiencing difficulty in finding support for their research and training reactors. There are currently only 28 university research reactors remaining across the United States. Many of these reactors were initially established with 30- to 40-yr operating licenses and will require re-licensing in the next several years. Combined, the university nuclear engineering educational programs and the university research reactors form a fundamental and vital component in a broad spectrum of our national research and education infrastructure and are critical to many national priorities such as energy, health care, education, environment, and technology transfer. Speakers have been selected from various universities, the Nuclear Energy Institute, and industry to address problems related to workforce forecasting, student recruiting and retention, research reactor operation and financing, academic accreditation, and other current issues relevant to nuclear engineering education and research.

    2011-01-01

    The extraordinary progress in the knowledge of infectious disease, the discovery of antibiotics and effective vaccines are among the great achievement of the nineteenth and twentieth centuries. These achievement have led to a dramatic reduction in the levels of mortality from these diseases. According to the World Health Organization, the term "re-emerging infectious diseases" refers to infectious diseases, which although well known, have not been of recent public health importance. However, climate change, migration, changes in health services, antibiotic resistance, population increase, international travel, the increase in the number of immune-depressed patients ,etc have lead to the re-emergence of these diseases. The climate changes are exposing sectors of the population to inadequate fresh air, water, food and resources for survival which, in consequence, provoke increases in both internal and international migration. In this particular period in which we find ourselves, characterized by globalization, the international community has become aware that the re-emergence of these diseases poses an important risk for public health underlines the necessity to adopt appropriate strategies for their prevention and control. The re-emerging diseases of the twenty-first century are a serious problem for public health and even though there has been enormous progress in medical science and in the battle against infectious diseases, they are still a long way from being really brought under control. A well organized monitoring system would enable the epidemiological characteristics of the infectious diseases to be analyzed and the success or otherwise of preventive interventions to be precisely evaluated. For this reason, the World Health Organization and the European Union have discussed the formation of a collaborative network for the monitoring and control of re-emerging diseases and has initiated special programmes.

    Vic Montemayor - No one has been more passionate about improving the quality and effectiveness of the teaching of Medical Physics than Bill Hendee. It was in August of 2008 that the first AAPM Workshop on Becoming a Better Teacher of Medical Physics was held, organized and run by Bill Hendee. This was followed up in July of 2010 with a summer school on the same topic, again organized by Bill. There has been continued interest in alternate approaches to teaching medical physics since those initial gatherings. The momentum established by these workshops is made clear each year in the annual Innovation in Medical Physics Education session, which highlights work being done in all forms of medical physics education, from one-on-one residencies or classroom presentations to large-scale program revisions and on-line resources for international audiences. This symposium, presented on behalf of the Education Council, highlights the work of three finalists from past Innovation in Education sessions. Each will be presenting their approaches to and innovations in teaching medical physics. It is hoped that audience members interested in trying something new in their teaching of medical physics will find some of these ideas and approaches readily applicable to their own classrooms. Rebecca Howell - The presentation will discuss ways to maximize classroom learning, i.e., increasing the amount of material covered while also enhancing students’ understanding of the broader implications of the course topics. Specifically, the presentation will focus on two teaching methodologies, project based learning and flip learning. These teaching methods will be illustrated using an example of graduate medical physics course where both are used in conjunction with traditional lectures. Additionally, the presentation will focus on our experience implementing these methods including challenges that were overcome.

  7. Scientist's Perceptions of Uncertainty During Discussions of Global Climate

    Science.gov (United States)

    Romanello, S.; Fortner, R.; Dervin, B.

    2003-04-01

    This research examines the nature of disagreements between natural and social scientists during discussions of global climate change. In particular, it explores whether the disagreements between natural and social scientists are related to the ontological, epistemological, or methodological nature of the uncertainty of global climate change during these discussions. A purposeful sample of 30 natural and social scientists recognized as experts in global climate change by the United States Global Change Research Program (USGCRP) and National Academies Committee on Global Change were interviewed to elicit their perceptions of disagreements during their three most troublesome discussions on global climate change. A mixed-method (qualitative plus quantitative research) approach with three independent variables was used to explore nature of uncertainty as a mediating variable in the relationships between academic training, level of sureness, level of knowledge, and position on global climate change, and the nature of disagreements and bridging strategies of natural and social scientists (Patton, 1997; Frechtling et al., 1997). This dissertation posits that it is the differences in the nature of uncertainty communicated by natural and social scientists and not sureness, knowledge, and position on global climate change that causes disagreements between the groups. By describing the nature of disagreements between natural and social scientists and illuminating bridging techniques scientists use during these disagreements, it is hoped that information collected from this research will create a better dialogue between the scientists studying global climate change by providing communication strategies which will allow those versed in one particular area to speak to non-experts whether they be other scientists, media officials, or the public. These tangible strategies can then be used by government agencies to create better communications and education plans, which can

    The aim of this paper is to identify and discuss the ethical considerations that have confronted and challenged the research team when researchers facilitate conversations using private electronic mail discussion lists. The use of electronic mail group conversations, as a collaborative data generation method, remains underdeveloped in nursing. Ethical challenges associated with this approach to data generation have only begun to be considered. As receipt of ethics approval for a study titled; 'Describing transition with people who live with chronic illness' we have been challenged by many ethical dilemmas, hence we believe it is timely to share the issues that have confronted the research team. These discussions are essential so we can understand the possibilities for research interaction, communication, and collaboration made possible by advanced information technologies. Our experiences in this study have increased our awareness for ongoing ethical discussions about privacy, confidentiality, consent, accountability and openness underpinning research with human participants when generating data using an electronic mail discussion group. We describe how we work at upholding these ethical principles focusing on informed consent, participant confidentiality and privacy, the participants as threats to themselves and one another, public-private confusion, employees with access, hackers and threats from the researchers. A variety of complex issues arise during cyberspace research that can make the application of traditional ethical standards troublesome. Communication in cyberspace alters the temporal, spatial and sensory components of human interaction, thereby challenging traditional ethical definitions and calling to question some basic assumptions about identity and ones right to keep aspects of it confidential. Nurse researchers are bound by human research ethics protocols; however, the nature of research by electronic mail generates moral issues as well as ethical

    It is the ultimate goal of the intended REACH process (Registration, Evaluation and Authorization of Chemicals) of the European Union to identify substances of hazardous properties and to evaluate the risks of human and environmental exposure. During the last few months there has been a controversial discussion as to what extent in vitro studies and consideration of structure activity relationship provide sufficient information to waive repeated exposure studies. Industry as well as certain regulatory agencies or NGOs support this approach and propose that repeated dose studies may only be required beyond 100 t/a. From a toxicological point of view it has to be stressed that this discussion primarily considers the cost reduction and protection of animals, whereas protection of human health and the environment are secondary. In vitro studies only allow identification of specific hazardous properties which can be detected by the specific test system. Moreover, appropriate information on the dose response of adverse effects, identification of thresholds and NOELs that are essential for risk characterization cannot be obtained from these studies. Consequently, identification of all relevant hazardous properties and endpoints of adverse effects can only be determined in the intact animal by repeated dose studies such as 28-day or 90-day studies. In the absence of such information the hazard identification is incomplete and there is no basis for appropriate risk assessment of human exposure. Thus, any waiving of repeated dose studies in animals bears the probability of unforeseen effects in case of acute or continuous human exposure. From this the undersigning European Toxicologists conclude: 1. The intention of REACH is to identify hazardous properties in order that a reliable risk assessment can be made and measures taken to deal with chemicals posing a significant risk. 2. The recent debate has centered on ways in which the well established in vivo methods for risk

    This article presents a Habermasian analysis of newspaper reporting of the debate surrounding the effect of the Australia-United States Free Trade Agreement (the FTA) on access to medicines through Australian patent law. Habermas's concept of the public sphere is utilised in determining whether discussion within the print media adequately conveyed complex legal issues to the public and facilitated democratic discussion. It was found that newspaper reporting generally failed to meet this standard.

    Full Text Available Abstract Background In rodent models and in humans the impact of gestational diets on the offspring's phenotype was shown experimentally and epidemiologically. Adverse environmental conditions during fetal development provoke an intrauterine adaptive response termed 'fetal programming', which may lead to both persistently biased responsiveness to extrinsic factors and permanent consequences for the organismal phenotype. This leads to the hypothesis that the offspring's transcriptome exhibits short-term and long-term changes, depending on the maternal diet. In order to contribute to a comprehensive inventory of genes and functional networks that are targets of nutritional programming initiated during fetal life, we applied whole-genome microarrays for expression profiling in a longitudinal experimental design covering prenatal, perinatal, juvenile, and adult ontogenetic stages in a porcine model. Pregnant sows were fed either a gestational low protein diet (LP, 6% CP or an adequate protein diet (AP, 12% CP. All offspring was nursed by foster sows receiving standard diets. After weaning, all offspring was fed standard diets ad libitum. Results Analyses of the hepatic gene expression of the offspring at prenatal (94 dies post conceptionem, dpc and postnatal stages (1, 28, 188 dies post natum, dpn included comparisons between dietary groups within stages as well as comparisons between ontogenetic stages within diets to separate diet-specific transcriptional changes and maturation processes. We observed differential expression of genes related to lipid metabolism (e.g. Fatty acid metabolism, Biosynthesis of steroids, Synthesis and degradation of ketone bodies, FA elongation in mitochondria, Bile acid synthesis and cell cycle regulation (e.g. Mitotic roles of PLK, G1/S checkpoint regulation, G2/M DNA damage checkpoint regulation. Notably, at stage 1 dpn no regulation of a distinct pathway was found in LP offspring. Conclusions The transcriptomic

    The fatal transmissions of highly pathogenic avian influenza A viruses (IAV) of the H5N1 subtype to humans and high titer replication in the respiratory tract indicate that these pathogens can overcome the bird-to-human species barrier. While type I interferons (IFN-α/β) are well described to contribute to the species barrier of many zoonotic viruses, current data to the role of these antiviral cytokines during human H5N1 IAV infections is limited and contradictory. We hypothesized an important role for the IFN system in limiting productive infection of avian H5N1 strains in human cells. Hence, we examined IFN-α/β gene activation by different avian and human H5N1 isolates, if the IFN-α/β response restricts H5N1 growth and whether the different strains were equally capable to regulate the IFN-α/β system via their IFN-antagonistic NS1 proteins. Two human H5N1 isolates and a seasonal H3N2 strain propagated efficiently in human respiratory cells and induced little IFN-β, whereas three purely avian H5N1 strains were attenuated for replication and provoked higher IFN secretion. Replication of avian viruses was significantly enhanced on interferon-deficient cells, and exogenous IFN potently limited the growth of all strains in human cells. Moreover, IFN-α/β activation by all strains depended on retinoic acid-inducible gene I excluding principal differences in receptor activation between the different viruses. Interestingly, all H5N1 NS1 proteins suppressed IFN-α/β induction comparably well to the NS1 of seasonal IAV. Thus, our study shows that H5N1 strains are heterogeneous in their capacity to activate human cells in an NS1-independent manner. Our findings also suggest that H5N1 viruses need to acquire adaptive changes to circumvent strong IFN-α/β activation in human host cells. Since no single amino acid polymorphism could be associated with a respective high- or low induction phenotype we propose that the necessary adaptations to overcome the human IFN

    This article reports an open discussion that took place during the Keenan Symposium "Meeting the Entropy Challenge" (held in Cambridge, Massachusetts, on October 4, 2007) following the short presentations—each reported as a separate article in the present volume—by Seth Lloyd, Owen Maroney, Silviu Guiasu, Ping Ao, Jochen Gemmer, Bernard Guy, Gian Paolo Beretta, Speranta Gheorghiu-Svirschevski, and Dorion Sagan. All panelists and the audience were asked to address the following questions • Why is the second law true? Is it an inviolable law of nature? If not, is it possible to develop a perpetual motion machine of the second kind? • Are second law limitations objective or subjective, real or apparent, due to the nature of physical states or the representation and manipulation of information? Is entropy a physical property in the same sense as energy is universally understood to be an intrinsic property of matter? • Does the second law conflict with quantum mechanics? Are the differences between mechanical and thermodynamic descriptions of physical phenomena reconcilable? Does the reversible law of motion of hamiltonian mechanics and quantum mechanics conflict with the empirical observation of irreversible phenomena?

Based on the trend of historical data, some forecast that second-law efficiency of energy conversion will reach 80% by the end of the century. What technologies are at sight that might hold this promise? • Nanotechnologies and microtechnologies point towards the development of microscopic heat engines? How do second law limitations map down to these scales? • Combustion is the principal way of converting the chemical energy of fossil fuels to thermal energy, but it is highly irreversible. Are there promising ways to reduce combustion irreversibility? Are fuel cells the only alternative to combustion?

Is it possible or impossible to build Maxwell demons that beat the second law by exploiting fluctuations? • Is the maximum entropy generation principle capable of unifying nonequilibrium molecular dynamics, chemical kinetics, nonlocal and nonequilibrium rheology, biological systems, natural structures, and cosmological evolution? • Research in quantum computation and quantum information has raised many fundamental questions about the foundations of quantum theory. Are any of these questions related to the second law?

    With the rapid development of information science, the ancient Traditional Chinese Medicine is combining with it rapidly, and forming a new discipline: Traditional Chinese Medicine (TCM) Informatics. TCM information digitalization is the process of digital processing, which uses modern information technology to obtain, process, store, and analyze TCM-related data, information, and knowledge. It gathers research, application development, and service in an integrated whole. This article systematically analyzes the key research issues of TCM informatics (e.g., on data resources, data standard, data system construction). Also, the methodology and technology of TCM information digitalization research are thoroughly discussed. The starting point of the research on traditional Chinese medical information digitalization was in question. The research from the current study research was drawn from collected information that was stored, transferred, and utilized. This process helped to place an emphasis on the topic, as well as extending its research areas. In addition, an innovative TCM information virtual study center was set up to support a great deal of fundamental work.

    A review of the Dizziness Handicap Inventory (DHI). NUMBER OF STUDIES: Seventy-four studies. Articles published between January 1990 and May 2012 were identified by searches in PubMed electronic database. Of the 227 articles meeting the inclusion criteria 74 were reviewed. These articles are discussed under nine topics; Reliability, validity and internal consistency of the original version of DHI, relationship between vestibular/balance tests and DHI, association between DHI and the other scales related to balance impairments, exploratory factor analysis of the DHI, screening version of DHI, translations of DHI into other languages, the role of DHI to assess the success of the treatment of balance disorder, DHI results in various vestibular disorders, general characteristics of DHI in patients with balance impairment. Self reported measures represent unique pieces of the information important for the management of dizzy patients. DHI is the most widely used self reported measurement of patients with dizziness. It has been translated into fourteen languages, so it is widely accepted.

  1. Discussion on posting and labeling for radioprotection

    2009-01-01

    The radioprotection aims the protection of people against exposure to ionizing radiation or radioactive substances as well as the safety of radiation sources. As ionizing radiation is not perceived by human senses, the warning signs and labels on radiation sources and the safety posters in controlled and supervised areas have an important role to keep the doses and risks as low as reasonably achievable, to prevent radiological accidents and to mitigate their consequences. In Brazil, several technical regulations require such safety labels and posters, however, despite their importance, there is quite few guidance about their format or contents. In this paper the posting and labeling requirements for radiological control existing in Brazilian technical regulations are discussed, confronting them with national, foreign and international technical standards and by drawing up a parallel with requirements of technical regulations from other countries. Changes are suggested in some parts of the national regulations, to prevent some differences in the current guidance, allowing the optimization of posting and labeling programs of radiological facilities.

    Full Text Available The research programme on vicarious learning, part of which we report in this paper, has been aimed at exploring the idea that learning can be facilitated by providing learners with access to the experiences of other learners. We use Bandura's term vicarious learning to describe this (Bandura, 1986, and we believe it to be a paradigm that offers particular promise when seen as an innovative way of exploiting recent technical advances in multimedia and distance learning technologies. It offers the prospect of a real alternative to the building of intelligent tutors (which directly address the problem of allowing learners access to dialogue, but which have proved largely intractable in practice or to the direct support of live dialogues (which do not offer a solution to the problem of providing 'live' tutors - unless they are between peer learners. In the research reported here our main objectives were to develop techniques to facilitate learners' access to, especially, dialogues and discussions which have arisen when other learners were faced with similar issues or problems in understanding the material. This required us to investigate means of indexing and retrieving appropriate dialogues and build on these to create an advanced prototype system for use in educational settings.

    2014-01-01

    This essay frames an invitation to pastoral counselors and pastoral theologians to examine connections and perhaps interactions between themselves and traditional shamanic healers who use ayahuasca in their healing ceremonies. Indigenous people in South America have used ayahuasca for centuries, and the ritual has become common among the mestizo populations in urban areas of the Amazon, particularly as a curing ritual for drug addiction (Dobkin de Rios, 1970; Moir, 1998). Like peyote in the United States (Calabrese, 1997) ayahuasca use amongst the indigenous people of the Amazon is a form of cultural psychiatry. A review of the literature reveals very little commentary or discussion of shamanic practice in Pastoral Counseling (Pastoral Theology). The scant literature identifies an antithetical relationship at best. The current authors wonder about the possibility of to including shamanic practices in the context of pastoral counseling? This essay seeks to provide some basic information about the ritual use of ayahuasca and to offer a rationale for pastoral counselors to engage in a dialogue about its utility.

  4. Discussion of entanglement entropy in quantum gravity

    We study entanglement entropy in gravity theory with quantum effects. A simplest model is a two dimensional Einstein gravity theory. We use an n-sheet manifold to obtain an area term of entanglement entropy by summing over all background fields. Based on AdS/CFT correspondence, strongly coupled conformal field theory is expected to describe perturbative quantum gravity theory. An ultraviolet complete quantum gravity theory should not depend on a choice of an entangling surface. To analysis the problem explicitly, we analyze two dimensional conformal field theory. We find that a coefficient of a universal term of entanglement entropy is independent of a choice of an entangling surface in two dimensional conformal field theory for one interval to show a tentative evidence. Finally, we discuss that translational invariance in a quantum system at zero temperature, size goes to infinity and no mass scales, except for cut-off, possibly be a necessary condition in quantum gravity theory by ruing out a volume law of entanglement entropy.

    The global burden of cancer is growing rapidly with an estimated 15 million new cases per year worldwide in 2015, growing to 19 million by 2025 and 24 million by 2035. The largest component of this growth will occur in low-to-middle income countries (LMICs). About half of these cases will require radiation treatment. The gap for available cancer treatment, including radiation therapy, between high-income countries (HICs) and LMICs is enormous. Accurate data and quantitative models to project the needs and the benefits of cancer treatment are a critical first step in closing the large cancer divide between LMICs and HICs. In this context, the Union for International Cancer Control (UICC) has developed a Global Task Force on Radiotherapy for Cancer Control (GTFRCC) with a charge to answer the question as to what it will take to close the gap between what exists today and reasonable access to radiation therapy globally by 2035 and what the potential clinical and economic benefits are for doing this. The Task Force has determined the projections of cancer incidence and the infrastructure required to provide access to radiation therapy globally. Furthermore it has shown that appropriate investment not only yields improved clinical outcomes for millions of patients but that it also provides an overall economic gain throughout all the income settings where this investment is made. This symposium will summarize the facets associated with this global cancer challenge by reviewing the cancer burden, looking at the requirements for radiation therapy, reviewing the benefits of providing such therapy both from a clinical and economic perspective and finally by looking at what approaches can be used to aid in the alleviation of this global cancer challenge. The speakers are world renowned experts in global public health issues (R. Atun), medical physics (D. Jaffray) and radiation oncology (N. Coleman).

    Full Text Available The task of identifying named entities from the discussion texts in Web forums faces the challenge of noisy names. As the names are often misspelled or abbreviated, the conventional techniques have failed to detect the noisy names properly. In this paper we propose a global context based framework for handling the noisy names. The framework is tested on a named entity recognition system designed to identify the names from the discussion texts in a homeopathy diagnosis discussion forum. The proposed global context-based framework is found to be effective in improving the accuracy of the named entity recognition system.

    Full Text Available This study focuses on the characterization of graphocentrism in microculture. We aim to describe, based on literacy studies, the presence of written language in the life of socially and historically situated subjects, thematizing the axiological capital of less favored socioeconomic contexts. Subjects are children undergoing schooling process, living in a district of Florianópolis, Santa Catarina, Brazil. Discussions on the theme are based on Barton (1994, Barton, Hamilton and Ivanic (2000, Heath (1982, and Street (1994, 2003. Looking at literacy from a sociocultural perspective implies understanding that subjects deal with written language in their daily life in different ways. It seems that school tends to teach subject matters defined beforehand, and this hampers the dialog with different social practices played by students who come from family environments with different schooling levels. This study is inserted in a project whose focus is the defense of a more sensible look of school concerning the different realities which constitute school itself, regarding the teaching of written language. The present research aims to answer the following questions: How can we configure the microculture (family, school, church, neighborhood – more or less graphocentric – where children attending 1st to 5th grade live, in an economically less privileged community of Florianópolis? How can we delineate the axiological capital regarding the mastering of written language by those children? What literacy events are more recurrent within that microculture? The data were collected by means of interviews, observations and field annotations, focusing on the visible elements of literacy events, similarly to what has been done by Hamiton (2000, such as participants, environments, artifacts, and activities. On the hand, the non-visible constituents of literacy practices, such as hidden participants, domain, resources, and routines, were observed during

    The preabortion interview required by French law takes place between the medical consultation and the aspiration or administration of RU-486. The three marriage counselors at the Center for Social Gynecology in Marseilles have each undertaken a course of personal therapy to enable them to understand their own reactions and motivations as a way of improving their effectiveness with clients. The preabortion interview is an opportunity to listen to and support women who may be experiencing anguish, sadness, ambivalence, or aggressivity. Each client determines the content of the interview. Often the reason for the abortion is given, frequently in terms of economic problems, unemployment, or other justification. The women almost always state that they "cannot", not that they "do not want", to continue the pregnancy, as if external circumstances had made their decision. The decision is usually made with little discussion. Young adolescents are often astounded to find themselves pregnant. Among young girls, the pregnancy may represent an appeal to the parents for attention or understanding. Sometimes the abortion represents a repetition or a reminder of some difficult event in the past, such as a previous abortion or the death of a child. Often the abortion exacerbates problems in the couple's relationship. The mother often experiences rejection of the pregnancy by the father as rejection of herself. Repeat abortions raise questions about whether some aspect of counseling was neglected. The abortion request always occasions a great feeling of guilt, both for being pregnant and for refusing the pregnancy. The interview permits the client to express her feelings and may help her make sense of the experience.

  13. Do randomized controlled trials discuss healthcare costs?

    Directory of Open Access Journals (Sweden)

    G Michael Allan

    Full Text Available BACKGROUND: Healthcare costs, particularly pharmaceutical costs, are a dominant issue for most healthcare organizations, but it is unclear if randomized controlled trials (RCTs routinely discuss costs. Our objective was to assess the frequency and factors associated with the inclusion of costs in RCTs. METHODS AND FINDINGS: We randomly sampled 188 RCTs spanning three years (2003-2005 from six high impact journals. The sample size for RCTs was based on a calculation to estimate the inclusion of actual drug costs with a precision of +/-3%. Two reviewers independently extracted cost data and study characteristics. Frequencies were calculated and potential characteristics associated with the inclusion of costs were explored. Actual drug costs were included in 4.7% (9/188 of RCTs; any actual costs were included in 7.4% (14/188 of RCTs; and any mention of costs was included in 27.7% (52/188 of RCTs. As the amount of industry funding increased across RCTs, from non-profit to mixed to fully industry funded RCTs, there was a statistically significant reduction in the number of RCTs with any actual costs (Cochran-Armitage test, p = 0.005 and any mention of costs (Cochran-Armitage test, p = 0.02. Logistic regression analysis also indicated funding was associated with the inclusion of any actual cost (OR = 0.34, p = 0.009 or any mention of costs (OR = 0.63, p = 0.02. Journal, study conclusions, study location, primary author's country and product age were not associated with inclusion of cost information. CONCLUSION: While physicians are encouraged to consider costs when prescribing drugs for their patients, actual drug costs were provided in only 5% of RCTs and were not mentioned at all in 72% of RCTs. Industry funded trials were less likely to include cost information. No other factors were associated with the inclusion of cost information.

    From an examination of the current sample of 12 pulsars with measured proper motions and the z-distribution of the much larger group of over 80 sources with measured period derivatives, we develop a self-consistent picture of pulsar evolution. The apparent tendency of pulsars to move parallel to the galactic plane is explained as the result of various selection effects. A method for calculating the unmeasurable radial velocity of a pulsar is presented; it is shown that the total space velocities thus obtained are consistent with the assumption of an extreme Population I origin for pulsars which subsequently move away from the plane with a large range of velocities. The time scale for pulsar magnetic field decay is derived from dynamical considerations. A strong correlation of the original pulsar field strength with the magnitude of pulsar velocity is discussed. This results in the division of pulsars into two classes: Class A sources characterized by low space velocities, a small scale height, and low values of P 0 P 0 ; and Class B sources with a large range of velocities (up to 1000 km s -1 ), a much greater scale height, and larger values of initial field strength. It is postulated that Class A sources originate in tight binaries where their impulse acceleration at birth is insufficient to remove them from the system, while the Class B sources arise from single stars or loosely bound binaries and are accelerated to high velocities by their asymmetric radiation force. The evolutionary picture which is developed is shown to be consistent with a number of constraints imposed by supernova rates, the relative frequency of massive binaries and Class A sources, theoretical field-decay times, and the overall pulsar galactic distribution

  15. Water, food, and population -- a panel discussion.

    Science.gov (United States)

    1996-01-01

    This paper summarizes a conference panel discussion among parliamentarians and researchers on water and food supplies and population growth in Asia. The Western Samoa legislator urged delegates to be aware of human development that was no more than the promotion of values associated with a market economy. Samoans increased their per capita caloric consumption. The food supply is provided locally, and 90% of exports are food products. Food security would be jeopardized by a fivefold increase in population. Samoan human development indicators were relatively good for a developing country. However, the country was still ranked as a low-income, food-deficit country. The Pakistani delegate explained that Pakistan's agriculture used the largest, continuous irrigation system in the world. However, the system operated inefficiently. There was concern that future high population growth would jeopardize food security. Another barrier was institutional mismanagement of irrigation and reliance on imports for staple items. Agricultural productivity must increase to meet the increased needs of continued population growth. All available land is currently under cultivation. Future strategies will necessitate international cooperation and innovative and environmentally sound technology. Professor Xuan remarked that increased population growth and rising demand, decreased water quality, and changing consumption patterns were a threat to water supplies. Sustainable increases in food production would entail better water management: reforestation to reduce and prevent water runoff, better technological exploitation of rain water, and more efficient use of irrigation systems. Better international financing schemes were needed for support of these policy changes. Professor Ness suggested free markets in water in order to price water at actual rates of consumption. Polluters should pay. Water management was also threatened by global warming.

    Healthcare costs, particularly pharmaceutical costs, are a dominant issue for most healthcare organizations, but it is unclear if randomized controlled trials (RCTs) routinely discuss costs. Our objective was to assess the frequency and factors associated with the inclusion of costs in RCTs. We randomly sampled 188 RCTs spanning three years (2003-2005) from six high impact journals. The sample size for RCTs was based on a calculation to estimate the inclusion of actual drug costs with a precision of +/-3%. Two reviewers independently extracted cost data and study characteristics. Frequencies were calculated and potential characteristics associated with the inclusion of costs were explored. Actual drug costs were included in 4.7% (9/188) of RCTs; any actual costs were included in 7.4% (14/188) of RCTs; and any mention of costs was included in 27.7% (52/188) of RCTs. As the amount of industry funding increased across RCTs, from non-profit to mixed to fully industry funded RCTs, there was a statistically significant reduction in the number of RCTs with any actual costs (Cochran-Armitage test, p = 0.005) and any mention of costs (Cochran-Armitage test, p = 0.02). Logistic regression analysis also indicated funding was associated with the inclusion of any actual cost (OR = 0.34, p = 0.009) or any mention of costs (OR = 0.63, p = 0.02). Journal, study conclusions, study location, primary author's country and product age were not associated with inclusion of cost information. While physicians are encouraged to consider costs when prescribing drugs for their patients, actual drug costs were provided in only 5% of RCTs and were not mentioned at all in 72% of RCTs. Industry funded trials were less likely to include cost information. No other factors were associated with the inclusion of cost information.

    Customers want high-quality products at low prices, and they want them now. The message is clear: The Public compares perceived alternatives. The communication problem of the nuclear industry is the same as any other nonmonopoly provider of products or services, i.e., to show the public that nuclear electricity is superior even though nuclear electricity itself is indistinguishable from any other electricity. The following topics are discussed in this paper: (1) What the public needs in general; (2) what the public wants of information delivered; (3) the nuclear information that the public wants; (4) the ANS public information web page; and (5) wider use of issues information

    An urgent need to rebuild public confidence after an incident attracting widespread adverse publicity led to the development by British Nuclear Fuels plc of a completely new approach to public relations. The Company's experience suggests that impressions count more than sheer information, provided the impressions have a firm base in reality. (author)

    Detection for space application is very demanding on the IR detector: all wavelengths, from visible-NIR (2- 3um cutoff) to LWIR (10-12.5um cutoff), even sometimes VLWIR (15um cutoff) may be of interest. Moreover, various scenarii are usually considered. Some are imaging applications where the focal plane array (FPA) is used as an optical element to sense an image. However, the FPA may also be used in spectrometric applications where light is triggered on the different pixels depending on its wavelength. In some cases, star pointing is another use of FPAs where the retina is used to sense the position of the satellite. In all those configurations, we might distinguish several categories of applications: • low flux applications where the FPA is staring at space and the detection occurs with only a few number of photons. • high flux applications where the FPA is usually staring at the earth. In this case, the black body emission of the earth and its atmosphere ensures usually a large number of photons to perform the detection. Those two different categories are highly dimensioning for the detector as it usually determines the level of dark current and quantum efficiency (QE) requirements. Indeed, high detection performance usually requires a large number of integrated photons such that high QE is needed for low flux applications, in order to limit the integration time as much as possible. Moreover, dark current requirement is also directly linked to the expected incoming flux, in order to limit as much as possible the SNR degradation due to dark charges vs photocharges. Note that in most cases, this dark current is highly depending on operating temperature which dominates detector consumption. A classical way to mitigate dark current is to cool down the detector to very low temperatures. This paper won't discuss the need for wavefront sensing where the number of detected photons is low because of a very narrow integration window. Rigorously, this kind of

    This paper is concerned with how forms of publics come into being in situations of technological innovation and change. The paper attends to sudden social formations which arise as responses to what is perceived of as threatening socio-technical inventions into the routine of everyday social life....... We revisit the Dewey-Lippmann debate, and we look at spontaneous citizens’ reactions towards emerging technologies such as Google Street View as well as we discuss some institutionally organized events of public engagement with science. As we explore the formation of publics inside and outside...
