  1. National policy dialogue on state and federal regulation of the electricity industry - staff report on a Keystone policy dialogue

    SciTech Connect

    1996-05-01

    For over two years, The Keystone Center facilitated a dialogue on State and Federal Regulation of the Electricity Industry. The intent of this report is to assist policy-makers faced with decisions about changes to traditional utility regulation and planning and provide an overview of a diverse group`s deliberations on regulatory jurisdictional conflicts. This report is not a consensus document, rather it is a staff written summary of two years of discussion on the issues. The participants in the Keystone Dialogue believed that all affected interests could benefit from, if nothing else, a summary of their discussions of state/federal issues. The electric utility industry is one of the last remaining, heavily regulated industries in the United States. Rate and corporate regulation is split between state and federal governments and there is distinct regulatory authority at each level. For example, retail rate regulation occurs at the state level, the Federal Energy Regulatory Commission is responsible for wholesale rate regulation under the Federal Power Act, and the Securities and Exchange Commission oversees registered utility holding companies as defined under the Public Utility Holding Company Act of 1935. This jurisdictional split between state and federal regulation has evolved over many years through legislation and litigation on such matters. The creation of this allocation of regulatory responsibility was initiated in 1935 with the passage of the Public Utility Holding Company Act and the Federal Power Act when the economic and technological changes that are now occurring in the industry simply could not have been envisioned.

  2. Utility planning using least-cost principles and the role of externalities - staff report on a Keystone policy dialogue

    SciTech Connect

    1996-05-01

    For over two years, The Keystone Center facilitated a two-phase dialogue on Utility Planning Using Least-Cost Principles and, in the second phase, on the role of Externalities. The intent of this report is to assist policy-makers faced with decisions about changes to traditional utility regulation and planning. This report is not a consensus document, rather it is staff written summary of two years of discussion on the issues. As a concept, least-cost planning has been discussed since the 1970`s and many states have implemented such programs since the mid-1980`s. Yet, the actual goals and objectives of least-cost planning remain a source of controversy between affected interest groups. Some industry observers believe that least-cost planning can help reconcile the often conflicting demands between increased capacity requirements and concerns about the external costs of power production. In traditional utility regulation practices, capital investments are rewarded and revenue is a direct function of sales. However, a number state public utility commissions have altered their practices to allow for returns on investments in more efficient end-use equipment (also known as ratebasing conservation) and adjusting revenues to account for sales lost due to utility conservation programs. Other states are planning these types of changes. Still others are observing the impacts of the changes before they commit.

    2014-04-01

    In order to examine the development of anthropological paradigms and their dialogue with medicine, I divide the discussion into two general, but non-exclusive, approaches: one that focuses on health and disease as social and cultural experience and construction, and another that examines health from an interactional and political perspective. For the first approach, I focus on North American and French theories that find resonance in the anthropological dialogue in Brazil. For the second political approach, the discussion originates in the dialogue among anthropologists in Latin America who have been developing models to contribute to an interdisciplinary approach necessary for health policies and intervention in health. The concepts of practices in self-care and intermedicality, among others, are explored due to their contribution in anthropology to public policies in health. These anthropologists have argued that health practices should be understood through the notions of autonomy, collectivity, agency and praxis, as opposed to the notions of the biomedical perspective characterized as being universalist, biological, individualist and a-historical.

  10. Celebrity Climate Contrarians: Understanding a keystone species in contemporary climate science-policy-public interactions

    NASA Astrophysics Data System (ADS)

    Boykoff, M. T.

    2012-12-01

    Since the 1980s, a keystone species called 'climate contrarians' has emerged and thrived. Through resistance to dominant interpretations of scientific evidence, and often outlier views on optimal responses to climate threats, contrarians have raised many meta-level questions: for instance, questions involve to what extent have their varied interventions been effective in terms of sparking a new and wise Copernican revolution; or do their amplified voices instead service entrenched carbon-based industry interests while they blend debates over 'climate change' with other culture wars? While the value of their influence has generated numerous debates, there is no doubt that climate contrarians have had significant influence on climate science, policy and public communities in ways that are larger than would be expected from their relative abundance in society. As such, a number of these actors have achieved 'celebrity status' in science-policy circles, and, at times, larger public spaces. This presentation focuses on how - particularly through amplified mass media attention to their movements - various outlier interventions have demonstrated themselves to be (often deliberately) detrimental to efforts that seek to enlarge rather than constrict the spectrum of possibility for mobilizing appropriate responses to ongoing climate challenges. Also, this work analyses the growth pathways of these charismatic megafauna through interview data and participant observations completed by the author at the 2011 Heartland Institute's Sixth International Conference on Climate Change. This provides detail on how outlier perspectives characterized as climate contrarians do work in these spaces under the guise of public intellectualism to achieve intended goals and objectives. The research undertaken and related in the presentation here seeks to better understand motivations that prop up these contrarian stances, such as possible ideological or evidentiary disagreement to the orthodox

  11. Social movement heterogeneity in public policy framing: A multi-stakeholder analysis of the Keystone XL pipeline

    NASA Astrophysics Data System (ADS)

    Wesley, David T. A.

    In 2011, stakeholders with differing objectives formed an alliance to oppose the Keystone XL heavy oil pipeline. The alliance, which came to be known as "Tar Sands Action," implemented various strategies, some of which were more successful than others. Tar Sands Action was a largely heterogeneous alliance that included indigenous tribes, environmentalists, ranchers, landowners, and trade unions, making it one of the more diverse social movement organizations in history. Each of these stakeholder categories had distinct demographic structures, representing an array of racial, ethnic, educational, occupational, and political backgrounds. Participants also had differing policy objectives that included combating climate change and protecting jobs, agricultural interests, water resources, wildlife, and human health. The current dissertation examines the Tar Sands Action movement to understand how heterogeneous social movement organizations mobilize supporters, maintain alliances, and create effective frames to achieve policy objectives. A multi-stakeholder analysis of the development, evolution and communication of frames concerning the Keystone XL controversy provides insight into the role of alliances, direct action, and the news media in challenging hegemonic frames. Previous research has ignored the potential value that SMO heterogeneity provides by treating social movements as culturally homogenous. However, diversity has been shown to affect performance in business organizations. The current study demonstrates that under some circumstances, diversity can also improve policy outcomes. Moreover, policy frames are shown to be more effective in sustaining news media and public interest through a process the author calls dynamic frame sequencing (DFS). DFS refers to a process implementing different stakeholder frames at strategically opportune moments. Finally, Tar Sands Action was one of the first SMOs to rely heavily on social media to build alliances, disseminate

    The Atlantic Council has cooperated in an ongoing dialogue on energy policy issues with key Japanese organizations for the past twelve years. These Japanese organizations are the Committee for Energy Policy Promotion (CEPP) and the Institute of Energy Economics (IEE). The members of CEPP are major energy supplier and user companies. The IEE conducts sophisticated research and prepares policy papers on a range of international and Japanese energy issues. This energy dialogue is the only long-term US-Japan dialogue which engages CEPP/IEE members. Over the past twelve years the US-Japan energy dialogue has met seventeen times, with alternating meetings held in Tokyo, Hawaii, and Washington, DC. While the dialogue is a private sector activity, US and Japanese government officials are kept informed on the program and are invited to participate in the meetings in Washington and Tokyo. Major benefits of this activity have included: Establishment of close working relationships among Japanese and US private sector energy institutions and experts; exchange of papers on energy issues among participants and on a selected basis to others in the private and governmental sectors; facilitation of separate US-Japanese work on policy issues - for example a joint US-Japan cooperative policy paper on global climate change published in 1991, some government representatives participated in a May 1991 meeting on this subject. Encouragement of Japanese participation in separate Atlantic Council programs on US energy policy imperatives (1990); technology cooperation with developing countries in the field of energy supply and use for sustainable development (1992); creation of a World Energy Efficiency Association (1993); and a US-Japan-Newly Independent States project on NIS energy policy (1992--1994).

    Keystone species structure ecological communities and are major determinants of biodiversity. A synthesis of research on keystone species is nonetheless missing a critical component -NDASH- the sensory mechanisms for behavioral interactions that determine population- and community-wide attributes. Here, we establish the chemosensory basis for keystone predation by sea stars (Pisaster ochraceus) on mussels. This consumer-resource interaction is prototypic of top-down driven trophic cascades. Each mussel species (Mytilus californianus and M. galloprovincialis) secretes a glycoprotein orthologue (29.6 and 28.1 kDa, respectively) that acts, singularly, to evoke the sea star predatory response. The orthologues (named 'KEYSTONEin') are localized in the epidermis, extrapallial fluid, and organic shell coating (periostracum) of live, intact mussels. Thus, KEYSTONEin contacts chemosensory receptors on tube feet as sea stars crawl over rocky surfaces in search of prey. The complete nucleotide sequences reveal that KEYSTONEin shares 87% (M. californianus) or 98% (M. galloprovincialis) homology with a calcium-binding protein in the shell matrix of a closely related congener, M. edulis. All three molecules cluster tightly within the Complement Component 1 Domain Containing (C1qDC) protein family; each exhibits a large globular domain, low complexity region(s), coiled coil, and at least four of five histidine-aspartic acid tandem motifs. Collective results support the hypothesis that KEYSTONEin evolved ancestrally in immunological, and later, in biomineralization roles. More recently, the substance has become exploited by sea stars as a contact cue for prey recognition. As the first identified compound to evoke keystone predation, KEYSTONEin provides valuable sensory information, promotes biodiversity, and shapes community structure and function. Without this molecule, there would be no predation by sea stars on mussels. This article is protected by copyright. All rights

    2009-12-16

    This article is part of a series written for people responsible for making decisions about health policies and programmes and for those who support these decision makers. Policy dialogues allow research evidence to be considered together with the views, experiences and tacit knowledge of those who will be involved in, or affected by, future decisions about a high-priority issue. Increasing interest in the use of policy dialogues has been fuelled by a number of factors: 1. The recognition of the need for locally contextualised 'decision support' for policymakers and other stakeholders 2. The recognition that research evidence is only one input into the decision-making processes of policymakers and other stakeholders 3. The recognition that many stakeholders can add significant value to these processes, and 4. The recognition that many stakeholders can take action to address high-priority issues, and not just policymakers. In this article, we suggest questions to guide those organising and using policy dialogues to support evidence-informed policymaking. These are: 1. Does the dialogue address a high-priority issue? 2. Does the dialogue provide opportunities to discuss the problem, options to address the problem, and key implementation considerations? 3. Is the dialogue informed by a pre-circulated policy brief and by a discussion about the full range of factors that can influence the policymaking process? 4. Does the dialogue ensure fair representation among those who will be involved in, or affected by, future decisions related to the issue? 5. Does the dialogue engage a facilitator, follow a rule about not attributing comments to individuals, and not aim for consensus? 6. Are outputs produced and follow-up activities undertaken to support action?

    The application of EquiFrame in the analysis of sexual and reproductive health policies by Ivanova et al to a new thematic area, their selection of only some of the Core Concepts of human rights in health service provision and the addition of new vulnerable groups relevant to the purpose of their analysis, are all very welcome developments. We also applaud their application of EquiFrame to policies in countries where it has not previously been used, along with their use of interviews with policy-makers to produce a deeper understanding of policy processes. We argue that clear justification for the inclusion of additional, or replacement of some exiting vulnerable groups within EquiFrame should be accompanied by clear definitions of such groups, along with the evidence-base that justifies their classification as a vulnerable or marginalised group. To illustrate the versatility of EquiFrame, we summarise a range of ways in which it has been used across a number of regions; including a brief Case Study of its use to develop the National Health Policy of Malawi. While EquiFrame focuses on policy content, we preview a new policy analysis tool – Equity and Inclusion in Policy Processes (EquIPP) – which assesses the extent of equity and inclusion in broader policy processes. Together, EquiFrame and EquIPP can be used to help governments and civil society ensure that policies are addressing the much stronger emphasis on social inclusion, now apparent in the Sustainable Development Goals (SDGs).

    Food is one of the determinants and conditions of health and an inherent right of all people. The consequences of food and nutrition insecurity in the population, such as obesity, malnutrition and specific nutritional deficiencies, impact the health sector and have historically meant that it has assumed the responsibility for food and nutrition programs and policies in Brazil. However, ensuring food and nutrition security requires a combination of public policies, among which the National Food and Nutrition Policy of the Unified Health System (SUS) plays a fundamental role. This paper seeks to contribute to the debate on intersectoriality and health promotion based on presenting the National Food and Nutrition Policy and discussing its role as interface between the SUS and the National Food and Nutrition Security Policy and System. This perspective strongly suggests the combination of efforts to promote health and food and nutrition security in order to optimize initiatives developed in different sectors and accompanied by different policy councils that are not interrelated, enabling enhanced government and civil society action on the determinants of health and nutrition.

  9. Human cloning laws, human dignity and the poverty of the policy making dialogue

    PubMed Central

    Caulfield, Timothy

    2003-01-01

    Background The regulation of human cloning continues to be a significant national and international policy issue. Despite years of intense academic and public debate, there is little clarity as to the philosophical foundations for many of the emerging policy choices. The notion of "human dignity" is commonly used to justify cloning laws. The basis for this justification is that reproductive human cloning necessarily infringes notions of human dignity. Discussion The author critiques one of the most commonly used ethical justifications for cloning laws – the idea that reproductive cloning necessarily infringes notions of human dignity. He points out that there is, in fact, little consensus on point and that the counter arguments are rarely reflected in formal policy. Rarely do domestic or international instruments provide an operational definition of human dignity and there is rarely an explanation of how, exactly, dignity is infringed in the context reproductive cloning. Summary It is the author's position that the lack of thoughtful analysis of the role of human dignity hurts the broader public debate about reproductive cloning, trivializes the value of human dignity as a normative principle and makes it nearly impossible to critique the actual justifications behind many of the proposed policies.

    The biological efficacy of nutritional supplements to complement usual diets in poor populations is well established. This knowledge rests on decades of methodologic research development and, more recently, on codification of methods to compile and interpret results across studies. The challenge now is to develop implementation (delivery) science knowledge and achieve a similar consensus on efficacy criteria for the delivery of these nutrients by public health and other organizations. This requires analysis of the major policy instruments for delivery and well-designed program delivery studies that examine the flow of a nutrient through a program impact pathway. This article discusses the differences between biological and program efficacy, and why elucidating the fidelity of delivery along the program impact pathways is essential for implementing a program efficacy trial and for assessing its internal and external validity. Research on program efficacy is expanding, but there is a lack of adequate frameworks to facilitate the process of harmonizing concepts and vocabulary, which is essential for communication among scientists, policy planners, and program implementers. There is an urgent need to elaborate these frameworks at national and program levels not only for program efficacy studies but also for the broader research agenda to support and improve the science of delivering adequate nutrition to those who need it most.

Since the importance of some species may largely be the consequence of their rich interaction structure, one possible quantitative approach to identify the most influential species is to study their position in the network of interspecific interactions. In this paper, I discuss the role of network analysis (and centrality indices in particular) in this process and present a new and simple approach to characterizing the interaction structures of each species in a complex network. Understanding the linkage between structure and dynamics is a condition to test the results of topological studies, I briefly overview our current knowledge on this issue. The study of key nodes in networks has become an increasingly general interest in several disciplines: I will discuss some parallels. Finally, I will argue that conservation biology needs to devote more attention to identify and conserve keystone species and relatively less attention to rarity. PMID:19451124

    This article studies the ways in which researchers working in the area of health and social research and using participatory visual methods might extend the reach of participant-generated creations such as photos and drawings to engage community leaders and policy-makers. Framed as going 'beyond engagement', the article explores the idea of the production of researcher-led digital dialogue tools, focusing on one example, based on a series of visual arts-based workshops with children from eight slums in Nairobi addressing issues of safety, security, and well-being in relation to housing. The authors conclude that there is a need for researchers to embark upon the use of visual tools to expand the life and use of visual productions, and in particular to ensure meaningful participation of communities in social change.

    Keystone species have a disproportionate influence on the structure and function of ecosystems. Here we analyze whether a keystone-like pattern can be observed in the relationship between transnational corporations and marine ecosystems globally. We show how thirteen corporations control 11-16% of the global marine catch (9-13 million tons) and 19-40% of the largest and most valuable stocks, including species that play important roles in their respective ecosystem. They dominate all segments of seafood production, operate through an extensive global network of subsidiaries and are profoundly involved in fisheries and aquaculture decision-making. Based on our findings, we define these companies as keystone actors of the Anthropocene. The phenomenon of keystone actors represents an increasingly important feature of the human-dominated world. Sustainable leadership by keystone actors could result in cascading effects throughout the entire seafood industry and enable a critical transition towards improved management of marine living resources and ecosystems.

  13. Probabilistic authenticated quantum dialogue

    Hwang, Tzonelih; Luo, Yi-Ping

    2015-12-01

    This work proposes a probabilistic authenticated quantum dialogue (PAQD) based on Bell states with the following notable features. (1) In our proposed scheme, the dialogue is encoded in a probabilistic way, i.e., the same messages can be encoded into different quantum states, whereas in the state-of-the-art authenticated quantum dialogue (AQD), the dialogue is encoded in a deterministic way; (2) the pre-shared secret key between two communicants can be reused without any security loophole; (3) each dialogue in the proposed PAQD can be exchanged within only one-step quantum communication and one-step classical communication. However, in the state-of-the-art AQD protocols, both communicants have to run a QKD protocol for each dialogue and each dialogue requires multiple quantum as well as classical communicational steps; (4) nevertheless, the proposed scheme can resist the man-in-the-middle attack, the modification attack, and even other well-known attacks.

  18. Models of Persuasion Dialogue

    NASA Astrophysics Data System (ADS)

    Prakken, Henry

    This chapter1 reviews formal dialogue systems for persuasion. In persuasion dialogues two or more participants try to resolve a conflict of opinion, each trying to persuade the other participants to adopt their point of view. Dialogue systems for persuasion regulate how such dialogues can be conducted and what their outcome is. Good dialogue systems ensure that conflicts of view can be resolved in a fair and effective way [6]. The term ‘persuasion dialogue’ was coined by Walton [13] as part of his influential classification of dialogues into six types according to their goal. While persuasion aims to resolve a difference of opinion, negotiation tries to resolve a conflict of interest by reaching a deal, information seeking aims at transferring information, deliberationdeliberation wants to reach a decision on a course of action, inquiry is aimed at “growth of knowledge and agreement” and quarrel is the verbal substitute of a fight. This classification leaves room for shifts of dialogues of one type to another. In particular, other types of dialogues can shift to persuasion when a conflict of opinion arises. For example, in information-seeking a conflict of opinion could arise on the credibility of a source of information, in deliberation the participants may disagree about likely effects of plans or actions and in negotiation they may disagree about the reasons why a proposal is in one’s interest.

    The formulas of image height in two-dimensional field about Gaussian and tilted imaging system of grating-based imaging spectrometer instrument (GISI) are deduced firstly, and the determined expressions of smile and keystone of GISI are obtained. It is proposed to correct the smile with off-axis lens, and the elimination effect of the smile is studied by means of spatial ray tracing. By controlling the degree of off-axis and the distribution of focal power of the off-axis lens, the long-wave infrared imaging spectrometer with well-eliminated smile and keystone is designed. The maximum of smile and keystone at working wavelengths in all fields of view are less than 8.57 μm and 13.33 μm, respectively.

  4. Impact of the Keystone XL pipeline on global oil markets and greenhouse gas emissions

    NASA Astrophysics Data System (ADS)

    Erickson, Peter; Lazarus, Michael

    2014-09-01

    Climate policy and analysis often focus on energy production and consumption, but seldom consider how energy transportation infrastructure shapes energy systems. US President Obama has recently brought these issues to the fore, stating that he would only approve the Keystone XL pipeline, connecting Canadian oil sands with US refineries and ports, if it `does not significantly exacerbate the problem of carbon pollution'. Here, we apply a simple model to understand the implications of the pipeline for greenhouse gas emissions as a function of any resulting increase in oil sands production. We find that for every barrel of increased production, global oil consumption would increase 0.6 barrels owing to the incremental decrease in global oil prices. As a result, and depending on the extent to which the pipeline leads to greater oil sands production, the net annual impact of Keystone XL could range from virtually none to 110 million tons CO2 equivalent annually. This spread is four times wider than found by the US State Department (1-27 million tons CO2e), who did not account for global oil market effects. The approach used here, common in lifecycle analysis, could also be applied to other pending fossil fuel extraction and supply infrastructure.

  5. Mistletoe as a keystone resource: an experimental test

    Watson, David M.; Herring, Matthew

    2012-01-01

    Various entities have been designated keystone resources, but few tests have been attempted and we are unaware of any experimental manipulations of purported keystone resources. Mistletoes (Loranthaceae) provide structural and nutritional resources within canopies, and their pervasive influence on diversity led to their designation as keystone resources. We quantified the effect of mistletoe on diversity with a woodland-scale experiment, comparing bird diversities before and after all mistletoe plants were removed from 17 treatment sites, with those of 11 control sites and 12 sites in which mistletoe was naturally absent. Three years after mistletoe removal, treatment woodlands lost, on average, 20.9 per cent of their total species richness, 26.5 per cent of woodland-dependent bird species and 34.8 per cent of their woodland-dependent residents, compared with moderate increases in control sites and no significant changes in mistletoe-free sites. Treatment sites lost greater proportions of birds recorded nesting in mistletoe, but changes in species recorded feeding on mistletoe did not differ from control sites. Having confirmed the status of mistletoe as a keystone resource, we suggest that nutrient enrichment via litter-fall is the main mechanism promoting species richness, driving small-scale heterogeneity in productivity and food availability for woodland animals. This explanation applies to other parasitic plants with high turnover of enriched leaves, and the community-scale influence of these plants is most apparent in low productivity systems.

    2006-10-01

    Intergroup dialogue is a public process designed to involve individuals and groups in an exploration of societal issues such as politics, racism, religion, and culture that are often flashpoints for polarization and social conflict. This article examines intergroup dialogue as a bridging mechanism through which social workers in clinical, other direct practice, organizer, activist, and other roles across the micro-macro practice spectrum can engage with people in conflict to advance advocacy, justice, and social change. We define intergroup dialogue and provide examples in not-for-profit or community-based and academic settings of how intergroup dialogue has been applied to conflicts around topics of race and ethnic nationality, sexual orientation, religion, and culture. We recommend practice-, policy-, and research-related actions that social workers can take to understand and use intergroup dialogue.

    Restoration of demised keystone-species populations is an overriding concern in conservation biology. However, since no population is independent of its environment, progress is needed in predicting the efficacy of restoration in unstable ecological contexts. Here, by means of Population Dynamics P-system Models (PDP), we studied long-term changes in the population size of Egyptian vultures (Neophron percnopterus) inhabiting a Natural Park, northern Spain, to changes in the numbers of wild rabbits (Oryctolagus cuniculus), a keystone-species of Mediterranean ecosystems that have suffered >90% population decline after a hemorrhagic disease outbreak. Low availability of rabbit carcasses leads Egyptian vultures to extend their foraging activities to unprotected areas with higher non-natural mortality whereas growing numbers of griffon vultures (Gyps fulvus), a dominant competitor, progressively monopolize trophic resources resulting in a focal population decrease. Modeling shows that, even if keystone-species populations recover in core protected areas, the return to the original studied population size may be unfeasible, due to both the high non-natural mortality rates in humanized areas and long-term changes in the scavenger guild structure. Policy decisions aimed to restore keystone-species should rely on holistic approaches integrating the effects of spatial heterogeneity on both producer and consumer populations as well as within-guild processes.

  14. Narrative, dialogue, and dissociation.

    PubMed

    Gedo, Paul M

    2014-02-01

    This paper explores dissociative phenomena as disruptions of dialogue between persons, and disruptions of internal narratives. A dissociating patient temporarily loses ability to convey his or her inner experience to the therapist. The disconnection between dialogue and internal experience can mislead both participants, or distract them from underlying connotations. Dissociation also disrupts the patient's sense of internal coherence and internal conversation. Dissociation represents a regression to an early, preverbal mode of (internal and external) communication. The challenge for the dyad is to restore dialogue and then to discern the multiply determined meanings of the dissociative communication. This therapeutic work allows the patient to achieve a more coherent sense of self and of his or her life course.

    Pharmacogenomics is a hybrid field of experimental science at the intersection of human disease genetics and clinical pharmacology sharing applications of the new genomic technologies. But this hybrid field is not yet stable or fully integrated, nor is science policy in pharmacogenomics fully equipped to resolve the challenges of this emerging hybrid field. The disciplines of human disease genetics and clinical pharmacology contain significant differences in their scientific practices. Whereas clinical pharmacology originates as an experimental science, human disease genetics is primarily observational in nature. The result is a significant asymmetry in scientific method that can differentially impact the degree to which gene-environment interactions are discerned and, by extension, the study sample size required in each discipline. Because the number of subjects enrolled in observational genetic studies of diseases is characteristically viewed as an important criterion of scientific validity and reliability, failure to recognize discipline-specific requirements for sample size may lead to inappropriate dismissal or silencing of meritorious, although smaller-scale, craft-based pharmacogenomic investigations using an experimental study design. Importantly, the recognition that pharmacogenomics is an experimental science creates an avenue for systematic policy response to the ethical imperative to prospectively pursue genetically customized therapies before regulatory approval of pharmaceuticals. To this end, we discuss the critical role of interdisciplinary engagement between medical sciences, policy, and social science. We emphasize the need for development of shared standards across scientific, methodologic, and socioethical epistemologic divides in the hybrid field of pharmacogenomics to best serve the interests of public health.

    The application of EquiFrame in the analysis of sexual and reproductive health policies by Ivanova et al to a new thematic area, their selection of only some of the Core Concepts of human rights in health service provision and the addition of new vulnerable groups relevant to the purpose of their analysis, are all very welcome developments. We also applaud their application of EquiFrame to policies in countries where it has not previously been used, along with their use of interviews with policy-makers to produce a deeper understanding of policy processes. We argue that clear justification for the inclusion of additional, or replacement of some exiting vulnerable groups within EquiFrame should be accompanied by clear definitions of such groups, along with the evidence-base that justifies their classification as a vulnerable or marginalised group. To illustrate the versatility of EquiFrame, we summarise a range of ways in which it has been used across a number of regions; including a brief Case Study of its use to develop the National Health Policy of Malawi. While EquiFrame focuses on policy content, we preview a new policy analysis tool - Equity and Inclusion in Policy Processes (EquIPP) - which assesses the extent of equity and inclusion in broader policy processes. Together, EquiFrame and EquIPP can be used to help governments and civil society ensure that policies are addressing the much stronger emphasis on social inclusion, now apparent in the Sustainable Development Goals (SDGs).

    The nuclear receptor superfamily consists of 48 mammalian transcription factors that regulate nearly all aspects of development, inflammation, and metabolism. Two subclasses, the Peroxisome Proliferator-Activated Receptors (PPARs) and Liver X Receptors (LXRs), are lipid-sensing receptors that have critical roles in lipid and glucose metabolism. The parallel epidemics of obesity and diabetes shine a spotlight on the potential for therapeutic manipulation of PPARs and LXRs to combat these diseases. In recognition of this, a recent Keystone Symposium was devoted to these metabolic receptors. Here, we summarize some of the major highlights and future projections discussed at the meeting.

    Many animal societies rely on highly influential keystone individuals for proper functioning. When information quality is important for group success, such keystone individuals have the potential to diminish group performance if they possess inaccurate information. Here, we test whether information quality (accurate or inaccurate) influences collective outcomes when keystone individuals are the first to acquire it. We trained keystone or generic individuals to attack or avoid novel stimuli and implanted these trained individuals within groups of naive colony-mates. We subsequently tracked how quickly groups learned about their environment in situations that matched (accurate information) or mismatched (inaccurate information) the training of the trained individual. We found that colonies with just one accurately informed individual were quicker to learn to attack a novel prey stimulus than colonies with no informed individuals. However, this effect was no more pronounced when the informed individual was a keystone individual. In contrast, keystones with inaccurate information had larger effects than generic individuals with identical information: groups containing keystones with inaccurate information took longer to learn to attack/avoid prey/predator stimuli and gained less weight than groups harbouring generic individuals with identical information. Our results convey that misinformed keystone individuals can become points of vulnerability for their societies. PMID:26817771

  14. Mammal population regulation, keystone processes and ecosystem dynamics.

    PubMed Central

    Sinclair, A R E

    2003-01-01

    The theory of regulation in animal populations is fundamental to understanding the dynamics of populations, the causes of mortality and how natural selection shapes the life history of species. In mammals, the great range in body size allows us to see how allometric relationships affect the mode of regulation. Resource limitation is the fundamental cause of regulation. Top-down limitation through predators is determined by four factors: (i). body size; (ii). the diversity of predators and prey in the system; (iii). whether prey are resident or migratory; and (iv). the presence of alternative prey for predators. Body size in mammals has two important consequences. First, mammals, particularly large species, can act as keystones that determine the diversity of an ecosystem. I show how keystone processes can, in principle, be measured using the example of the wildebeest in the Serengeti ecosystem. Second, mammals act as ecological landscapers by altering vegetation succession. Mammals alter physical structure, ecological function and species diversity in most terrestrial biomes. In general, there is a close interaction between allometry, population regulation, life history and ecosystem dynamics. These relationships are relevant to applied aspects of conservation and pest management. PMID:14561329

    The terrain around Keystone Lake, a 388-acre lake in northwest Hillsborough County, Florida, near the Cosme well field, is dotted with sinks that promote leakage from the surficial aquifer to the underlying Floridan aquifer. The lake, an integral part of the Brooker Creek channel, receives overland runoff from cypress swamps, pastures, citrus groves, and lakefront residential areas. The lake, a composite of many coalescing sinkholes, is generally 14 to 16 ft deep and has been dredged in places to 23 ft deep. Since 1960, rainfall in the area shows a cumulative negative departure of 86 in. from the long-term average. The mean annual lake stage in 1973 was the lowest on record. Concurrently, municipal pumpage in the Cosme well field from the Floridan aquifer peaked in 1961 and again in 1973, and in 1972 the potentiometric surface was the lowest since 1960. Comparisons of the hydrographs of lake stage and the potentiometric surface in the Floridan aquifer with rainfall graphs shows that both correspond closely to seasonal rainfall, resulting in the trend of decreasing seasonal maximum levels in the lake and the aquifer. Keystone Lake water quality is adequate for recreation and propagation of wildlife. (Woodard-USGS)

    2016-01-01

    Facilitative or positive interactions are ubiquitous in nature and play a fundamental role in the configuration of ecological communities. In particular, habitat modification and niche construction, in which one organism locally modifies abiotic conditions and favours other organisms by buffering the effects of adverse environmental factors, are among the most relevant facilitative interactions. In line with this, ‘keystone structures’, which provide resources, refuge, or advantageous services decisive for other species, may allow the coexistence of various species and thus considerably contribute to diversity maintenance. Beech cupules are woody husks harbouring beech fruits that remain in the forest soil for relatively long periods of time. In this study, we explored the potential role of these cupules in the distribution and maintenance of the soil fauna inhabiting the leaf litter layer. We experimentally manipulated cupule availability and soil moisture in the field to determine if such structures are limiting and can provide moist shelter to soil animals during drought periods, contributing to minimize desiccation risks. We measured invertebrate abundances inside relative to outside the cupules, total abundances in the leaf litter and animal body sizes, in both dry and wet experimental plots. We found that these structures are preferentially used by the most abundant groups of smaller soil animals—springtails, mites and enchytraeids—during droughts. Moreover, beech cupules can be limiting, as an increase in use was found with higher cupule densities, and are important resources for many small soil invertebrates, driving the spatial structure of the soil community and promoting higher densities in the leaf litter, probably through an increase in habitat heterogeneity. We propose that fruit woody structures should be considered ‘keystone structures’ that contribute to soil community maintenance. Therefore, beech trees may indirectly facilitate soil

    In January 2006, the Stardust mission will return the first samples from a solid solar-system body since Apollo, and the first samples of contemporary interstellar dust ever collected. Although sophisticated laboratory instruments exist for the analysis of Stardust samples, techniques for the recovery of particles and particle residues from aerogel collectors remain primitive. Here we describe our recent progress in developing techniques for extracting small volumes of aerogel, which we have called ''keystones,'' which completely contain particle impacts but minimize the damage to the surrounding aerogel collector. These keystones can be fixed to custom-designed micromachined silicon fixtures (so-called ''microforklifts''). In this configuration the samples are self-supporting, which can be advantageous in situations in which interference from a supporting substrate is undesirable. The keystones may also be extracted and placed onto a substrate without a fixture. We have also demonstrated the capability of homologously crushing these unmounted keystones for analysis techniques which demand flat samples.

  10. The legacy effects of keystone individuals on collective behaviour scale to how long they remain within a group

    PubMed Central

    Pruitt, Jonathan N.; Pinter-Wollman, Noa

    2015-01-01

    The collective behaviour of social groups is often strongly influenced by one or few individuals, termed here ‘keystone individuals’. We examined whether the influence of keystone individuals on collective behaviour lingers after their departure and whether these lingering effects scale with their tenure in the group. In the social spider, Stegodyphus dumicola, colonies' boldest individuals wield a disproportionately large influence over colony behaviour. We experimentally manipulated keystones' tenure in laboratory-housed colonies and tracked their legacy effects on collective prey capture following their removal. We found that bolder keystones caused more aggressive collective foraging behaviour and catalysed greater inter-individual variation in boldness within their colonies. The longer keystones remained in a colony, the longer both of these effects lingered after their departure. Our data demonstrate that, long after their disappearance, keystones have large and lasting effects on social dynamics at both the individual and colony levels. PMID:26336171

    2016-11-23

    In epiphytic orchids, distinctive groups of fungi are involved in the symbiotic association. However, little is known about the factors that determine the mycorrhizal community structure. Here, we analyzed the orchid mycorrhizal fungi communities associated with three sympatric Cymbidieae epiphytic tropical orchids (Cyrtochilum flexuosum, Cyrtochilum myanthum, and Maxillaria calantha) at two sites located within the mountain rainforest of southern Ecuador. To characterize these communities at each orchid population, the ITS2 region was analyzed by Illumina MiSeq technology. Fifty-five mycorrhizal fungi operational taxonomic units (OTUs) putatively attributed to members of Serendipitaceae, Ceratobasidiaceae and Tulasnellaceae were identified. Significant differences in mycorrhizal communities were detected between the three sympatric orchid species as well as among sites/populations. Interestingly, some mycorrhizal OTUs overlapped among orchid populations. Our results suggested that populations of studied epiphytic orchids have site-adjusted mycorrhizal communities structured around keystone fungal species. Interaction with multiple mycorrhizal fungi could favor orchid site occurrence and co-existence among several orchid species.

    As a person invested in personal doctoring, what promises are you willing to make about when and where you will "be there" for others? Attendees of the G. Gayle Stephens Keystone IV Conference answered that question on submitted index cards and through ongoing conference discussions. Those data were analyzed using grounded theory and combined to develop the following answer in aggregate: We will be held accountable to those who need us. We understand the need for expertise and compassion as we help others to navigate the intersection of science and humanism. We will serve as leaders in personal, public, and political conversations. We will mark a path for the profession ensuring alignment of personal practices with professional principles. We will not allow the needed conversations of processes, data points, and determinations of value to undermine our relationships with our patients. We will be there for you. Attentive and fully present. We will care for you when you have no need and you do not ask. We will center that care in your lived experience of health and illness, knowing you over time. We will be here for you now, over time and across distance, in ways that foster the feeling of wholeness and belonging.

  14. Invasive Asian Earthworms Negatively Impact Keystone Terrestrial Salamanders

    PubMed Central

    Ziemba, Julie L.

    2016-01-01

    Asian pheretimoid earthworms (e.g. Amynthas and Metaphire spp.) are invading North American forests and consuming the vital detrital layer that forest floor biota [including the keystone species Plethodon cinereus (Eastern Red-backed Salamander)], rely on for protection, food, and habitat. Plethodon cinereus population declines have been associated with leaf litter loss following the invasion of several exotic earthworm species, but there have been few studies on the specific interactions between pheretimoid earthworms and P. cinereus. Since some species of large and active pheretimoids spatially overlap with salamanders beneath natural cover objects and in detritus, they may distinctively compound the negative consequences of earthworm-mediated resource degradation by physically disturbing important salamander activities (foraging, mating, and egg brooding). We predicted that earthworms would exclude salamanders from high quality microhabitat, reduce foraging efficiency, and negatively affect salamander fitness. In laboratory trials, salamanders used lower quality microhabitat and consumed fewer flies in the presence of earthworms. In a natural field experiment, conducted on salamander populations from “non-invaded” and “pheretimoid invaded” sites in Ohio, salamanders and earthworms shared cover objects ~60% less than expected. Earthworm abundance was negatively associated with juvenile and male salamander abundance, but had no relationship with female salamander abundance. There was no effect of pheretimoid invasion on salamander body condition. Juvenile and non-resident male salamanders do not hold stable territories centered beneath cover objects such as rocks or logs, which results in reduced access to prey, greater risk of desiccation, and dispersal pressure. Habitat degradation and physical exclusion of salamanders from cover objects may hinder juvenile and male salamander performance, ultimately reducing recruitment and salamander abundance

    Oyster reefs provide myriad ecosystem services, including water quality improvement, fisheries and other faunal support, shoreline protection from erosion and storm surge, and economic productivity. However, their role in directing flow during non-storm conditions has been largely neglected. In regions where oyster reefs form near the mouth of estuarine rivers, they likely alter ocean-estuary exchange by acting as fresh water "dams". We hypothesize that these reefs have the potential to detain fresh water and influence salinity over extensive areas, thus providing a "keystone" ecosystem service by supporting estuarine functions that rely on the maintenance of estuarine (i.e., brackish) conditions in the near-shore environment. In this work, we investigated the effects of shore-parallel reefs on estuarine salinity using field data and hydrodynamic modeling in a degraded reef complex in the northeastern Gulf of Mexico. Results suggested that freshwater detention by long linear chains of oyster reefs plays an important role in modulating salinities, not only in the oysters' local environment, but over extensive estuarine areas (tens of square kilometers). Field data confirmed the presence of salinity differences between landward and seaward sides of the reef, with long-term mean salinity differences of >30% between sides. Modeled results expanded experimental findings by illustrating how oyster reefs affect the lateral and offshore extent of freshwater influence. In general, the effects of simulated reefs were most pronounced when they were highest in elevation, without gaps, and when riverine discharge was low. Taken together, these results describe a poorly documented ecosystem service provided by oyster reefs; provide an estimate of the magnitude and spatial extent of this service; and offer quantitative information to help guide future oyster reef restoration.

  16. Keystone characteristics that support cultural resilience in Karen refugee parents

    This participatory action research study used the conceptual framework of social-ecological resilience to explore how Karen (pronounced Ka·rén) refugee parents re-construct cultural resilience in resettlement. The funds of knowledge approach helped to define essential knowledge used by Karen parents within their own community. Framing this study around the concept of resilience situated it within an emancipatory paradigm: refugee parents were actors choosing their own cultural identity and making decisions about what cultural knowledge was important for the science education of their children. Sustainability science with its capacity to absorb indigenous knowledge as legitimate scientific knowledge offered a critical platform for reconciling Karen knowledge with scientific knowledge for science education. Photovoice, participant observation, and semi-structured interviews were used to create visual and written narrative portraits of Karen parents. Narrative analysis revealed that Karen parents had constructed a counter-narrative in Burma and Thailand that enabled them to resist assimilation into the dominant ethnic culture; by contrast, their narrative of life in resettlement in the U.S. focused on the potential for self-determination. Keystone characteristics that contributed to cultural resilience were identified to be the community garden and education as a gateway to a transformed future. Anchored in a cultural tradition of farming, these Karen parents gained perspective and comfort in continuity and the potential of self-determination rooted in the land. Therefore, a cross-cultural learning community for Karen elementary school students that incorporates the Karen language and Karen self-sustaining knowledge of horticulture would be an appropriate venue for building a climate of reciprocity for science learning.

  17. Invasive Asian Earthworms Negatively Impact Keystone Terrestrial Salamanders.

    2016-01-01

    Asian pheretimoid earthworms (e.g. Amynthas and Metaphire spp.) are invading North American forests and consuming the vital detrital layer that forest floor biota [including the keystone species Plethodon cinereus (Eastern Red-backed Salamander)], rely on for protection, food, and habitat. Plethodon cinereus population declines have been associated with leaf litter loss following the invasion of several exotic earthworm species, but there have been few studies on the specific interactions between pheretimoid earthworms and P. cinereus. Since some species of large and active pheretimoids spatially overlap with salamanders beneath natural cover objects and in detritus, they may distinctively compound the negative consequences of earthworm-mediated resource degradation by physically disturbing important salamander activities (foraging, mating, and egg brooding). We predicted that earthworms would exclude salamanders from high quality microhabitat, reduce foraging efficiency, and negatively affect salamander fitness. In laboratory trials, salamanders used lower quality microhabitat and consumed fewer flies in the presence of earthworms. In a natural field experiment, conducted on salamander populations from "non-invaded" and "pheretimoid invaded" sites in Ohio, salamanders and earthworms shared cover objects ~60% less than expected. Earthworm abundance was negatively associated with juvenile and male salamander abundance, but had no relationship with female salamander abundance. There was no effect of pheretimoid invasion on salamander body condition. Juvenile and non-resident male salamanders do not hold stable territories centered beneath cover objects such as rocks or logs, which results in reduced access to prey, greater risk of desiccation, and dispersal pressure. Habitat degradation and physical exclusion of salamanders from cover objects may hinder juvenile and male salamander performance, ultimately reducing recruitment and salamander abundance following Asian

  18. Tropical forest fragmentation limits pollination of a keystone understory herb.

    Loss of native vegetation cover is thought to be a major driver of declines in pollination success worldwide. However, it is not well known whether reducing the fragmentation of remaining vegetation can ameliorate these negative effects. We tested the independent effects of composition vs. configuration on the reproductive success of a keystone tropical forest herb (Heliconia tortuosa). To do this we designed a large-scale mensurative experiment that independently varied connected forest-patch size (configuration) and surrounding amount of forest (composition). In each patch, we tested whether pollen tubes, fruit, and seed set were associated with these landscape variables. We also captured hummingbirds as an indication of pollinator availability in a subset of patches according to the same design. We found evidence for an effect of configuration on seed set of H. tortuosa, but not on other aspects of plant reproduction; proportion of seeds produced increased 40% across the gradient in patch size we observed (0.64 to > 1300 ha), independent of the amount of forest in the surrounding landscape at both local and landscape scales. We also found that the availability of pollinators was dependent upon forest configuration; hummingbird capture rates increased three and one-half times across the patch size gradient, independent of forest amount. Finally, pollinator availability was strongly positively correlated with seed set. We hypothesize that the effects of configuration on plant fitness that we observed are due to reduced pollen quality resulting from altered hummingbird availability and/or movement behavior. Our results suggest that prioritizing larger patches of tropical forest may be particularly important for conservation of this species.

    This text approaches the necessary dialogue among different knowledge and considers the advances within Nursing in the search for consistence and clarity within the Nursing discipline. Towards this end, the text is based upon transdisciplinarity, intersectorality, complexity, and the interaction of different pairs in health and other areas, as well as the sustainance of scientific and technological space within Nursing. It argues perspectives that open possibilities for scientific and technological knowledge construction within a more responsible and mutual social commitment. The purpose of the paperis to amplify the aptitude for contextualization and globalize different knowledge, as well as transcend differences and peculiarities within the perspective of more qualitative policies which may overcome disciplinary barriers.

    Research on the experiences of faculty of color in predominantly White institutions (PWIs) suggests that they often experience the campus climate as invalidating, alienating, and hostile. Few studies, however, have actually focused on the classroom experiences of faculty of color when difficult racial dialogues occur. Using Consensually Qualitative Research, eight faculty of color were interviewed about their experiences in the classroom when racially tinged topics arose. Three major findings emerged. First, difficult racial dialogues were frequently instigated by the presence of racial microaggressions delivered toward students of color or the professor. Dialogues on race were made more difficult when the classrooms were diverse, when heated emotions arose, when there was a strong fear of self-disclosure, and when racial perspectives differed. Second, all faculty experienced an internal struggle between balancing their own values and beliefs with an attempt to remain objective. This conflict was often described as exhausting and energy-depleting. Third, faculty of color described both successful and unsuccessful strategies in facilitating difficult dialogues on race that arose in the course of their teaching. These findings have major implications for how PWIs can develop new programs, policies, and practices that will aid and support colleagues of color.

    2008-07-01

    This paper attempts to advance the thinking in Stetsenko's paper by situating the concepts of relational ontology and transformative activist stance in the context of coteaching and cogenerative dialogue. In so doing, we hope to make Stetsenko's ideas more operational in terms of access and application by researchers, teachers, policy makers and other stakeholders in education. Stetsenko argues that moving from relational ontology to a transformative activist stance can be considered as moving from participation to contribution. When this model was applied to coteaching and cogenerative dialogue, it was apparent that the coteaching and cogenerative dialogue moved further, from contribution to shared contribution, adding even greater potential for transformation. The paper also discusses the use of cultural historical activity theory in articulating the relationships, dynamics and interpretations of coteaching and cogenerative dialogue in relation to the wider context of their application.

    The selection of forest fragments for conservation is usually based on spatial parameters as forest size and canopy integrity. This strategy assumes that chosen fragments present high conservation status, ensuring biodiversity and ecological functions. We argue that a well-preserved forest fragment that remains connected by the landscape structure, does not necessarily hold attributes that ensure the presence of keystone species. We also discuss that the presence of keystone species does not always mean that it has the best conditions for its occurrence and maintenance. We developed a model to select areas in forest landscapes to be prioritized for protection based on suitability curves that unify and compare spatial indicators of three categories: forest fragment quality, landscape quality, and environmental conditions for the occurrence of a keystone species. We use a case study to compare different suitability degrees for Euterpe edulis presence, considered an important functional element in Atlantic Forest (São Paulo, Brazil) landscapes and a forest resource for local people. The results show that the identification of medium or advanced stage fragments as singular indicator of forest quality does not guarantee the existence or maintenance of this keystone species. Even in some well-preserved forest fragments, connected to others and with palm presence, the reverse J-shaped distribution of the population size structure is not sustained and these forests continue to be threatened due to human disturbances.

    Summary: The keystone flap, an emerging reconstructive option that can be used in many parts of the body, is gaining popularity among reconstructive surgeons. These reliable and versatile flaps can be used for large myelomeningocele closure. A modified bilateral keystone flap was used to achieve tension-free closure of a large thoracolumbar myelomeningocele associated with severe kyphosis in a newborn girl. The flap was modified by undermining in the subfascial plane in the medial aspect of the middle third. This undermining was performed to facilitate flap movement while preserving random musculocutaneous perforators captured within the island of tissues. Laterally, we approached the border of the latissimus dorsi and dissected in the submuscular plane instead of the subfascial plane to preserve more muscular fasciocutaneous perforators. We achieved soft-tissue coverage that was durable, stable, and protective. Wound healing was prompt, and the patient had a satisfactory cosmetic result. No postoperative complications were observed, such as flap necrosis, dehiscence, leakage of cerebrospinal fluid, or infection. The proposed modified keystone flap is a promising addition to the armament of reconstructive surgeons that might improve outcomes and minimize complications in myelomeningocele repair. Keystone flaps provide an ideal reconstructive option for large thoracolumbar myelomeningocele repair. They are reliable, robust, and aesthetically acceptable. PMID:28293496

    The National Institute of Diabetes, Digestive, and Kidney Diseases-supported Kidney Research National Dialogue asked the scientific community to formulate and prioritize research objectives that would improve our understanding of kidney function and disease. Kidney Research National Dialogue participants identified the need to improve outcomes in ESRD by decreasing mortality and morbidity and enhancing quality of life as high priority areas in kidney research. To reach these goals, we must identify retained toxins in kidney disease, accelerate technologic advances in dialysate composition and devices to remove these toxins, advance vascular access, and identify measures that decrease the burden of disease in maintenance dialysis patients. Together, these research objectives provide a path forward for improving patient-centered outcomes in ESRD.

    Figure analysis is a novel active learning teaching technique that reinforces visual literacy. Small groups of students discuss diagrams in class in order to learn content. The instructor then gives a brief introduction and later summarizes the content of the figure. This teaching technique can be used in place of lecture as a mechanism to deliver information to students. Here, a "how to" guide is presented in the form of an in-class dialogue, displaying the difficulties in visual interpretation that some students may experience while figure analysis is being implemented in an upper-level, cell biology course. Additionally, the dialogue serves as a guide for instructors who may implement the active learning technique as they consider how to respond to students' concerns in class. © 2016 by The International Union of Biochemistry and Molecular Biology, 44(4):345-348, 2016.

    Spiliotopoulos, Dimitris; Stavropoulou, Pepi; Kouroupetroglou, Georgios

    Usability is a fundamental requirement for natural language interfaces. Usability evaluation reflects the impact of the interface and the acceptance from the users. This work examines the potential of usability evaluation in terms of issues and methodologies for spoken dialogue interfaces along with the appropriate designer-needs analysis. It unfolds the perspective to the usability integration in the spoken language interface design lifecycle and provides a framework description for creating and testing usable content and applications for conversational interfaces. Main concerns include the problem identification of design issues for usability design and evaluation, the use of customer experience for the design of voice interfaces and dialogue, and the problems that arise from real-life deployment. Moreover it presents a real-life paradigm of a hands-on approach for applying usability methodologies in a spoken dialogue application environment to compare against a DTMF approach. Finally, the scope and interpretation of results from both the designer and the user standpoint of usability evaluation are discussed.

    2010-05-01

    Collaborative interdisciplinary working is central to contemporary health policy. The specialized and co-ordinated multidisciplinary care provided in stroke units is considered to contribute to improved patient outcomes in such units. However, how stroke unit teams co-ordinate their work is not clearly understood. This paper reports on a grounded theory study which explains how health professionals in two stroke units in northern England achieved teamwork. Data were generated through 220 hours of participant observation and 34 semi-structured interviews. Interviews were undertaken during and following participant observations. A basic social process common to teamworking in both units was identified; this was termed "opportunistic dialogue". The division of labour in respect of rehabilitation activities was negotiated through this interactional process. Co-location of most team members led to repeated engagement in sharing patient information and in exploring different perspectives. Opportunistic dialoguing contributed to mutual learning and explained the shift in thinking and team culture as team members moved from concern with discrete disciplinary actions to dialogue and negotiations focused on meeting patients' needs. The findings indicate that routinely incorporating periods of joint working in which team members articulate the reasoning for their decisions and interventions, contributes to achieving interdisciplinary teamworking in rehabilitation settings.

We found that, as a result of participation in dialogue, laypeople's attitudes toward scientists were more positive and scientists' and laypeople's attitudes toward HBT tended to converge. Additionally, laypeople reported increased communicative self-efficacy after the dialogue experience. However, effects in some cases differed by dialogue format. Implications for practice and research are discussed.

  13. Three dialogues concerning robots in elder care.

    The three dialogues in this contribution concern 21st century application of life-like robots in the care of older adults. They depict conversations set in the near future, involving a philosopher (Dr Phonius) and a nurse (Dr Myloss) who manages care at a large facility for assisted living. In their first dialogue, the speakers discover that their quite different attitudes towards human-robot interaction parallel fundamental differences separating their respective concepts of consciousness. The second dialogue similarly uncovers deeply contrasting notions of personhood that appear to be associated with respective communities of nursing and robotics. The additional key awareness that arises in their final dialogue links applications of life-like robots in the care of older adults with potential transformations in our understandings of ourselves - indeed, in our understandings of the nature of our own humanity. This series of dialogues, therefore, appears to address a topic in nursing philosophy that merits our careful attention.

    Species with extensive geographic ranges may interact with different species assemblages at distant locations, with the result that the nature of the interactions may vary spatially. Black-tailed prairie dogs Cynomys ludovicianus occur from Canada to Mexico in grasslands of the western Great Plains of North America. Black-tailed prairie dogs alter vegetation and dig extensive burrow systems that alter grassland habitats for plants and other animal species. These alterations of habitat justify the descriptor " ecological engineer," and the resulting changes in species composition have earned them status as a keystone species. We examined the impact of black-tailed prairie dogs on small mammal assemblages by trapping at on- and off-colony locations at eight study areas across the species' geographic range. We posed 2 nested hypotheses: 1) prairie dogs function as a keystone species for other rodent species; and 2) the keystone role varies spatially. Assuming that it does, we asked what are the sources of the variation? Black-tailed prairie dogs consistently functioned as a keystone species in that there were strong statistically significant differences in community composition on versus off prairie dog colonies across the species range in prairie grassland. Small mammal species composition varied along both latitudinal and longitudinal gradients, and species richness varied from 4 to 11. Assemblages closer together were more similar; such correlations approximately doubled when including only on- or off-colony grids. Black-tailed prairie dogs had a significant effect on associated rodent assemblages that varied regionally, dependent upon the composition of the local rodent species pool. Over the range of the black-tailed prairie dog, on-colony rodent richness and evenness were less variable, and species composition was more consistent than off-colony assemblages. ?? 2010 The Authors.

  15. Keystone conference on environmental biotechnology. Summary -- Results of conference

    SciTech Connect

    1995-12-31

    This symposium brought together a unique mix of scientists, engineers and policy makers to discuss the latest applications of biotechnology to in situ bioremediation and ex situ biodegradation of pollutants and industrial wastes. Several new topics were prominent in the discussions. Chief among these were issues related to environmentally acceptable endpoints, command and control versus incentive driven regulations, bioavailability of pollutants to microbial action, delivery of biodegrading organisms to pollutant plumes, value added production, and genetic probes for monitoring the status of soil consortia. These new issues gave a new perspective to the more traditional topics of the molecular genetics of microorganisms, marine bioremediation, bioprocessing of industrial and agricultural wastes, and engineered bioremediation systems which were featured.

  16. Therapeutic doubt and moral dialogue.

    PubMed

    Solbakk, Jan Helge

    2004-02-01

    This paper aims at analysing the problem of remainder and regret in moral conflicts. Four different approaches are subject of investigation: a moral-theoretical strategy aimed at consistency; a narrative approach of moral coherence and open consensus; Plato's moral methodology of dialogue and aporetic resolution of moral conflicts and finally, an approach deduced from Greek tragedy of emotional resolution of moral conflicts. A central argument is that since there exists no theoretically convincing way of solving the problem of remainder and regret, the attention should instead be directed towards finding alternative ways of coping with this problem. The three last approaches subject of investigation attempt--each in their own way--to do this. Teaching medical ethics to medical students and the burning issue of medical fallibility is used to demonstrate the relevance of these forms of resolution in a medical context.

    The National Institute of Diabetes and Digestive and Kidney Diseases-supported Kidney Research National Dialogue (KRND) asked the scientific community to formulate and prioritize research objectives that would improve our understanding of kidney function and disease. Several high-priority objectives for diabetic nephropathy were identified in data and sample collection, hypothesis generation, hypothesis testing, and translation promotion. The lack of readily available human samples linked to comprehensive phenotypic, clinical, and demographic data remains a significant obstacle. With data and biological samples in place, several possibilities exist for using new technologies to develop hypotheses. Testing novel disease mechanisms with state-of-the-art tools should continue to be the foundation of the investigative community. Research must be translated to improve diagnosis and treatment of people. The objectives identified by the KRND provide the research community with future opportunities for improving the prevention, diagnosis, and treatment of diabetic nephropathy.

    2013-05-06

    Current high-resolution push-broom hyperspectral cameras introduce keystone errors to the captured data. Efforts to correct these errors in hardware severely limit the optical design, in particular with respect to light throughput and spatial resolution, while at the same time the residual keystone often remains large. The mixel camera solves this problem by combining a hardware component--an array of light mixing chambers--with a mathematical method that restores the hyperspectral data to its keystone-free form, based on the data that was recorded onto the sensor with large keystone. A Virtual Camera software, that was developed specifically for this purpose, was used to compare the performance of the mixel camera to traditional cameras that correct keystone in hardware. The mixel camera can collect at least four times more light than most current high-resolution hyperspectral cameras, and simulations have shown that the mixel camera will be photon-noise limited--even in bright light--with a significantly improved signal-to-noise ratio compared to traditional cameras. A prototype has been built and is being tested.

    It is not clear how policy-making in the field of reproductive health relates to changes associated with programmes for the reform of the health sector in developing countries. There has been little communication between these two areas, yet policy on reproductive health has to be implemented in the context of structural change. This paper examines factors that limit dialogue between the two areas and proposes the following framework for encouraging it: the identification of policy groups and the development of bases for collaborative links between them; the introduction of a common understanding around relevant policy contexts; reaching agreement on compatible aims relating to reproductive health and health sector change; developing causal links between policy content in reproductive health and health sector change as a basis for evidence-based policy-making; and strengthening policy-making structures, systems, skills, and values.

    2014-01-01

    We present a Dynamic Energy Budget (DEB) model for the quintessential keystone predator, the rocky-intertidal sea star Pisaster ochraceus. Based on first principles, DEB theory is used to illuminate underlying physiological processes (maintenance, growth, development, and reproduction), thus providing a framework to predict individual-level responses to environmental change. We parameterized the model for P. ochraceus using both data from the literature and experiments conducted specifically for the DEB framework. We devoted special attention to the model’s capacity to (1) describe growth trajectories at different life-stages, including pelagic larval and post-metamorphic phases, (2) simulate shrinkage when prey availability is insufficient to meet maintenance requirements, and (3) deal with the combined effects of changing body temperature and food supply. We further validated the model using an independent growth data set. Using standard statistics to compare model outputs with real data (e.g. Mean Absolute Percent Error, MAPE) we demonstrated that the model is capable of tracking P. ochraceus’ growth in length at different life-stages (larvae: MAPE = 12.27%; post-metamorphic, MAPE = 9.22%), as well as quantifying reproductive output index. However, the model’s skill dropped when trying to predict changes in body mass (MAPE = 24.59%), potentially because of the challenge of precisely anticipating spawning events. Interestingly, the model revealed that P. ochraceus reserves contribute little to total biomass, suggesting that animals draw energy from structure when food is limited. The latter appears to drive indeterminate growth dynamics in P. ochraceus. Individual-based mechanistic models, which can illuminate underlying physiological responses, offer a viable framework for forecasting population dynamics in the keystone predator Pisaster ochraceus. The DEB model herein represents a critical step in that direction, especially in a period of

    Predation, competition, and their interaction are known to be important factors that influence the structure of ecological communities. In particular, in those cases where a competitive hierarchy exists among prey species, the presence of certain keystone predators can result in enhanced diversity in the prey community. However, little is known regarding the influence of keystone predator presence on invaded prey communities. Given the widespread occurrence of invasive species and substantial concern regarding their ecological impacts, studies on this topic are needed. In this study I used naturalistic replications of an experimental tadpole assemblage to assess the influence of predatory eastern newts, Notophthalmus viridescens, on the outcome of interspecific competition among native and nonindigenous tadpoles. When newts were absent, the presence of the tadpoles of one invasive species, the Cuban treefrog, Osteopilus septentrionalis, resulted in decreased survival and growth rate of the dominant native species, Bufo terrestris, and dominance of the tadpole assemblage by O. septentrionalis. However, the presence of one adult newt generally reduced or eliminated the negative impacts of O. septentrionalis tadpoles, resulting in comparable survival and performance of native species in invaded and noninvaded treatments. Differential mortality among the tadpole species suggests that newts preyed selectively on O. septentrionalis tadpoles, supporting the hypothesis that newts acted as keystone predators in the invaded assemblage. The presence of nonindigenous larval cane toads, Bufo marinus, did not significantly affect native species, and this species was not negatively affected by the presence of newts. Collectively, these results suggest that eastern newts significantly modified the competitive hierarchy of the invaded tadpole assemblage and reduced the impacts of a competitively superior invasive species. If general, these results suggest that the presence of

    In response to an alarming rise in human immunodeficiency virus (HIV) infection among Brazilian women during the early 1990s, the Sociedade Civil Bem-Estar Familiar no Brazil (BEMFAM) developed a project that integrates HIV prevention with clinical services, community-based prevention activities, and sexually transmitted disease diagnosis and treatment. Preliminary interviews with clinic clients revealed that women's fears they would be considered unfaithful were impeding their ability to suggest condom use to their sexual partners. Condom use within a relationship was considered appropriate only for pregnancy prevention. To facilitate dialogue about sexual health, BEMFAM developed a women's group intervention project. All women who attend a BEMFAM clinic are invited to participate in a one-hour group discussion before receiving medical services. Novela-style booklets with stories and characters women can relate to their own lives are used to stimulate discussion. Participants learn to use condoms correctly by putting them on a penis model and anticipate situations in which they would be able to negotiate condom use. The group setting enables women to gain confidence and practice assertiveness in a non-threatening, supportive environment. Their identification with other women's stories empowers women to take control of their health and sexual lives. Between October 1994 and July 1995, 3464 women participated in group discussions organized by BEMFAM and 40,688 condoms were distributed; 18% of these women returned to the clinic for additional condoms.

    Rhytidoponera violacea (Forel) (Hymenoptera: Formicidae) is a keystone seed disperser in Kwongan heathl and habitats of southwestern Australia. Like many myrmecochorous ants, little is known about the basic biology of this species. In this study various aspects of the biology of R. violacea were examined and the researchers evaluated how these characteristics may influence seed dispersal. R. violacea nesting habits (relatively shallow nests), foraging behavior (scramble competitor and lax food selection criteria), and other life history characteristics complement their role as a mutualist that interacts with the seeds of many plant species.

    TransCanada's proposed international crude oil pipeline route over sensitive, relatively pristine, subirrigated land underlain by the Ogallala aquifer led to increased scrutiny and eventual rejection of the Keystone XL pipeline. Pipeline routing could be made much more acceptable by adopting risk-managed routes that lessen the potential to adversely impact high-quality groundwater and, should a release occur, decrease the longevity of hazardous groundwater contaminants. Threats to water quality are taken quite seriously in states like Nebraska where 85% of the population depend on groundwater for potable water.

    What do the behavior of monkeys in captivity and the financial system have in common? The nodes in such social systems relate to each other through multiple and keystone networks, not just one network. Each network in the system has its own topology, and the interactions among the system's networks change over time. In such systems, the lead into a crisis appears to be characterized by a decoupling of the networks from the keystone network. This decoupling can also be seen in the crumbling of the keystone's power structure toward a more horizontal hierarchy. This paper develops nonparametric methods for describing the joint model of the latent architecture of interconnected networks in order to describe this process of decoupling, and hence provide an early warning system of an impending crisis.

    2015-03-01

    This study examined the changes in community composition of reef fishes by experimentally manipulating the availability of shelter provided by tabular structures on a mid-shelf reef on the Great Barrier Reef. At locations where access to tabular corals ( Acropora hyacinthus and Acropora cytherea) was excluded, a rapid and sustained reduction in the abundance of large reef fishes occurred. At locations where tabular structure was added, the abundance and diversity of large reef fishes increased and the abundance of small reef fishes tended to decrease, although over a longer time frame. Based on their response to changes in the availability of tabular structures, nine families of large reef fishes were separated into three categories; designated as obligate, facultative or non-structure users. This relationship may relate to the particular ecological demands of each family, including avoidance of predation and ultraviolet radiation, access to feeding areas and reef navigation. This study highlights the importance of tabular corals for large reef fishes in shallow reef environments and provides a possible mechanism for local changes in the abundance of reef fishes following loss of structural complexity on coral reefs. Keystone structures have a distinct structure and disproportionate effect on their ecosystem relative to their abundance, as such the result of this study suggests tabular corals may constitute keystone structures on shallow coral reefs.

    Health care-associated infections affect an estimated 5% of hospitalized patients and represent one of the leading causes of illness and death in the United States. This study calculates the costs and benefits of a patient safety program in intensive care units in 6 hospitals that were part of the Michigan Keystone ICU Patient Safety Program. On average, 29.9 catheter-related bloodstream infections and 18.0 cases of ventilator-associated pneumonia were averted per hospital on an annual basis. The average cost of the intervention is $3375 per infection averted, measured in 2007 dollars. The cost of the intervention is substantially less than estimates of the additional health care costs associated with these infections, which range from $12 208 to $56 167 per infection episode. These results do not take into account the additional effect of the Michigan Keystone program in terms of reducing cases of sepsis or its effects in terms of preventing mortality, improving teamwork, and reducing nurse turnover.

  13. The role of a keystone fault in triggering the complex El Mayor-Cucapah earthquake rupture

    2016-04-01

    The 2010 Mw 7.2 El Mayor-Cucapah earthquake in Baja California, Mexico activated slip on multiple faults of diverse orientations, which is commonly the case for large earthquakes. The critical stress level for fault failure depends on fault orientation and is lowest for optimally oriented faults positioned approximately 30° to the greatest principal compressive stress. Yet, misoriented faults whose positioning is not conducive to rupture are also common. Here we use stress inversions of surface displacement and seismic data to show that the El Mayor-Cucapah earthquake initiated on a fault that, owing to its orientation, was among those that required the greatest stress for failure. Although other optimally oriented faults must have reached critical stress earlier in the interseismic period, Coulomb stress modelling shows that slip on these faults was initially muted because they were pinned, held in place by misoriented faults that helped regulate their slip. In this way, faults of diverse orientations could be maintained at critical stress without destabilizing the network. We propose that regional stress build-up continues until a misoriented keystone fault reaches its threshold and its failure then spreads spontaneously across the network in a large earthquake. Our keystone fault hypothesis explains seismogenic failure of severely misoriented faults such as the San Andreas fault and the entire class of low-angle normal faults.

    The Keystone IV Conference was a touchstone moment for multigenerational conversations regarding our health care system and an opportunity to reconnect with the values of personal doctoring as a vocation. It inspired participants to renew commitments to relationships, healthy communities, and social change. Keystone IV was also a stark reminder of the need to rekindle family medicine's counterculture flame in today's tumultuous health care environment and reclaim the role of personal doctors in American society. Reimagining and reigniting the fire of personal relationship is today's counterculture movement for primary care. Personal doctors must heed the call for immediate action, which requires defining when relationships matter most in health care and understanding how to harness paradigm shifts in information technology, team-based care, and population health to strengthen, rather than undermine, personal doctoring. Simultaneously, we must also invent a new notion of personal doctoring that creates partnerships with patients and families to drive forward a social movement demanding health care focused on the whole person in the context of his or her community. Change will occur when patients insist on a personal doctoring approach as an essential priority for what they expect from the health care system-that anything less is unacceptable.

    2009-03-01

    Many plant species are threatened as a result of extinction of their large-bodied frugivores all over the world. Additionally, introduced herbivores and seed predators may cause severe pressure on early stages of plant recruitment. We studied the seed dispersal and seed predation of the keystone palm Euterpe edulis on a land-bridge island with a highly impoverished frugivore fauna and overabundant seed predators, and in a continuous Atlantic forest in Brazil. While the diversity of avian seed dispersers and predators was higher on the mainland, the abundance of seed dispersers was 4-fold higher on the island. Turdus flavipes was responsible for 72% and 96% of seeds removed in the island and mainland, respectively. However, the higher density of T. flaviceps on the island did not result in higher seed removal. In fact, seed removal rate was 1.7 times lower there than on the mainland, probably due to the aggressive behavior of the major seed disperser who defend palm fruits. Seed predation, on the other hand, was markedly higher on the island, where nearly 100% of seeds were preyed upon, but only 0.3% on the mainland. As a consequence of higher seed predation the population of E. edulis has few numbers of seedlings and saplings on the island. Therefore, management of the seed predator populations on the island is a key priority for recovering the natural population of this keystone palm and the frugivores that depend on its fruits.

    Experimental studies were conducted to assess the susceptibility of white-tailed deer (Odocoileus virginianus), gray squirrels (Sciurus carolinensis), and cottontail rabbits (Sylvilagus floridanus) to Jamestown Canyon (JC) and/or Keystone (KEY) virus infection. Viremia occurred in 5 of 6 deer inoculated with JC virus; however, all deer developed KEY virus neutralizing antibody. Based on the observation that antibody elicited by primary infection of deer with either KEY or JC virus exhibited partial heterologous neutralization in vitro, cross-challenge experiments were performed in these animals. Keystone virus failed to infect deer 30 days post primary JC virus infection; however, deer became infected when challenged with KEY virus 80 days after the initial JC virus infection as indicated by a substantial increase in antibody titer. Similarly, JC virus failed to produce viremia in immune animals infected with KEY virus 80 days previously, although 2 of the 3 animals challenged had serological evidence of infection. Three field-collected cottontail rabbits with no evidence of KEY antibody were readily susceptible to KEY virus infection and developed viremias of 1-4 days' duration; rabbits with KEY virus antibody did not develop viremia upon KEY virus challenge. Eight antibody-negative field-collected gray squirrels became viremic following injection with KEY virus; however, a comparable group of squirrels did not become viremic when injected with JC virus.

    Numerous scholars have suggested that the standard knowledge base of the field of special education is not a suitable intellectual foundation for the development of research, policy, and practice in the field of inclusive education. Still, we have yet to have a dialogue on what conceptual foundations may be most generative for the growth and development of the field of inclusive education. This article imagines and initiates such a new dialogue among educational researchers and teacher educators about the intellectual resources that can best support inclusive educators everywhere. As inclusive education gets increasingly taken up within international policy discourses, it may be imperative to explore and identify theories and ideas that can be responsive to diverse and hugely unequal contexts of schooling. This article forwards an initial collection of intellectual resources for an inclusive education that can accommodate such complex schooling conditions and invites rich scholarly exchange on this issue.

  18. Quantum Secure Dialogue with Quantum Encryption

    2014-09-01

    How to solve the information leakage problem has become the research focus of quantum dialogue. In this paper, in order to overcome the information leakage problem in quantum dialogue, a novel approach for sharing the initial quantum state privately between communicators, i.e., quantum encryption sharing, is proposed by utilizing the idea of quantum encryption. The proposed protocol uses EPR pairs as the private quantum key to encrypt and decrypt the traveling photons, which can be repeatedly used after rotation. Due to quantum encryption sharing, the public announcement on the state of the initial quantum state is omitted, thus the information leakage problem is overcome. The information-theoretical efficiency of the proposed protocol is nearly 100%, much higher than previous information leakage resistant quantum dialogue protocols. Moreover, the proposed protocol only needs single-photon measurements and nearly uses single photons as quantum resource so that it is convenient to implement in practice.

  19. Race talk: the psychology of racial dialogues.

    PubMed

    Sue, Derald Wing

    2013-11-01

    Constructive dialogues on race have been proposed as a means to heal racial and ethnic divides, reduce prejudice and misinformation, increase racial literacy, and foster improved race relations. Studies on the psychology of racial dialogues indicate social and academic norms that dictate against race talk between White Americans and persons of color: (a) the politeness protocol, (b) the academic protocol, and (c) the color-blind protocol. These protocols discourage race talk and allow society to enter into a conspiracy of silence regarding the detrimental impact oppression plays on persons of color. Facilitating difficult dialogues on race requires educators to recognize what makes such discussions difficult. For people of color, engaging in race talk exposes them to microaggressions that invalidate and assail their racial/ethnic identities. For Whites, honest discussions are impeded by fears of appearing racist, of realizing their racism, of acknowledging White privilege, and of taking responsibility to combat racism.

  9. Reversing Present Day Northern Plains Ecosystem Water Supply Stressors Resulting from the Near Extinction of Three Keystone Species

    NASA Astrophysics Data System (ADS)

    Collins, M. R.

    2006-05-01

    Near-extinction of three keystone species (the beaver, the bison, and the prairie dog) had a measurable negative influence on the local and regional climate, and water availability in the Northern Great Plains ecosystem compared to pre-contact conditions. Restoration of these three keystone species may have a significant positive influence by increasing the recharge rate to the aquifers and raising soil moisture due to the sharp hooves and wallows of the bison, prairie dog burrows, and beaver dams providing avenues of ingress. Predictions 1) The recharge of the aquifer will be greater where these three keystone species are present because of the prairie dog burrows, buffalo hooves and wallows, and beaver dams in comparison to the control area; 2) The entire ecosystem will be rejuvenated where the three species are permitted to return; 3) The microclimate changes caused by this reintroduction will stimulate an observable, measurable improvement in water supply when allowed to proceed to near pre-contact conditions. Next Steps 1) Inventory research area containing bison, prairie dog, and beaver versus control plot. (keystone species absent). 2) Measure the soil moisture, water table, water influx rates. 3) Monitor changes over time. 4) Later phase manipulation: Beaver re-introduction into severely damaged riparian area. 5) Link to Northern Plains NEON Initiative. Current Activity 1. Candidate study locations on Standing Rock reservation have been selected and evaluated for suitability, both as study site with beaver activity and a control site with beaver absent. 2. Research mentor identified and selected. Dr. Carol Johnston of South Dakota State University, Director of the Center for Biocomplexity Studies has graciously agreed to oversee my research project 3. Review of previous work is nearing completion. 4.

    Droughts are increasing in severity and frequency, yet the mechanisms that strengthen ecosystem resilience to this stress remain poorly understood. Here, we test whether positive interactions in the form of a mutualism between mussels and dominant cordgrass in salt marshes enhance ecosystem resistance to and recovery from drought. Surveys spanning 250 km of southeastern US coastline reveal spatially dispersed mussel mounds increased cordgrass survival during severe drought by 5- to 25-times. Surveys and mussel addition experiments indicate this positive effect of mussels on cordgrass was due to mounds enhancing water storage and reducing soil salinity stress. Observations and models then demonstrate that surviving cordgrass patches associated with mussels function as nuclei for vegetative re-growth and, despite covering only 0.1-12% of die-offs, markedly shorten marsh recovery periods. These results indicate that mutualisms, in supporting stress-resistant patches, can play a disproportionately large, keystone role in enhancing ecosystem resilience to climatic extremes.

  11. Habitat fragmentation, percolation theory and the conservation of a keystone species

    Many species survive in specialized habitats. When these habitats are destroyed or fragmented the threat of extinction looms. In this paper, we use percolation theory to consider how an environment may fragment. We then develop a stochastic, spatially explicit, individual-based model to consider the effect of habitat fragmentation on a keystone species (the army ant Eciton burchelli) in a neo tropical rainforest. The results suggest that species may become extinct even in huge reserves before their habitat is fully fragmented; this has important implications for conservation. We show that sustainable forest-harvesting strategies may not be as successful as is currently thought. We also suggest that habitat corridors, once thought of as the saviour for fragmented environments, may have a detrimental effect on population persistence.

    Myrmecochory (dispersal of seeds by ants) is an evolutionarily and ecologically common mutualism. Most of the research on the costs and benefits of myrmecochory in North America assumes that ant-dispersed seeds are taken to, and left in, the ant nest. Here, we use a novel seed-tracking technique to quantify secondary dispersal of seeds from the nest into the surrounding leaf litter by the keystone seed-dispersing ant, Aphaenogaster rudis. We found that A. rudis redispersed >90% of the seeds it took into its nest an average distance of 51.5 cm. A mathematical model shows redispersal increases the rate of population spread of the myrmecochores Hexastylis arifolia and Asarum canadense by 22.5%, and increases the expected cumulative dispersal distance away from the parent plant by 24%. Our results suggest myrmecochory benefits plants in eastern North American forests by increasing the distance between the seed and parent plant and reducing competition among siblings.

    Production of hydrocarbons from the Chevron 7C H.E. Lovett well, Keystone (Holt) field, is from the upper part of the Glorieta formation (Leonardian). The field is located near the western margin of the Central Basin platform (Permian basin) on a present-day structural high. The 116-ft (35.4-m) core contains at least 7 cycles of deposition, which consist, upward from the base, of progradational subtidal, intertidal and supratidal deposits. Supratidal deposits predominantly consist of dolostones with fenestral cavities; sabkha deposits are not represented. Scattered nodules of nonevaporitic anhydrite have been emplaced within subtidally deposited carbonates after dolomitization. Intrabiopelgrapestone grainstones, oointrabiopelgrainstones, intrabiopelpackstones and wackestones, and intrapelpackstones and wackestones are the predominant lithofacies. Dolostone is the predominant lithology.

    Abstract Background  Collaboration with patients in healthcare and medical research is an emerging development. We aimed to develop a methodology for health research agenda setting processes grounded in the notion of participation as dialogue. Methods  We conducted seven case studies between 2003 and 2007 to develop and validate a Dialogue Model for patient participation in health research agenda setting. The case studies related to spinal cord injury, neuromuscular diseases, renal failure, asthma/chronic obstructive pulmonary disease, burns, diabetes and intellectual disabilities. Results  The Dialogue Model is grounded in participatory and interactive approaches and has been adjusted on the basis of pilot work. It has six phases: exploration; consultation; prioritization; integration; programming; and implementation. These phases are discussed and illustrated with a case description of research agenda setting relating to burns. Conclusions  The dialogue model appeared relevant and feasible to structure the process of collaboration between stakeholders in several research agenda setting processes. The phase of consultation enables patients to develop their own voice and agenda, and prepares them for the broader collaboration with other stakeholder groups. Challenges include the stimulation of more permanent changes in research, and institutional transitions. PMID:20536537

  7. Recruitment dynamics in a rainforest seedling community: context-independent impact of a keystone consumer.

    PubMed

    2008-05-01

    The influence of keystone consumers on community structure is frequently context-dependent; the same species plays a central organising role in some situations, but not others. On Christmas Island, in the Indian Ocean, a single species of omnivorous land crab, Gecarcoidea natalis, dominates the forest floor across intact rainforest. We hypothesised that this consumer plays a key role in regulating seedling recruitment and in controlling litter dynamics on the island, independent of the type of vegetation in which it occurred. To test this hypothesis, we conducted crab exclusion experiments in two forest types on the island and followed the dynamics of seedling recruitment and litter processing for six years. To determine if these effects were likely to be general across the island, we compared land crab densities and seedling abundance and diversity at ten sites across island rainforest. Surveys across island rainforest showed that seedlings of species susceptible to predation by land crabs are consistently rare. Abundance and diversity of these species were negatively correlated to red crab abundance. Although red land crabs may be important determinants of seedling recruitment to the overstorey, differences in overstorey and seedling composition at the sites suggests that recruitment of vulnerable trees still occurs at a temporal scale exceeding that of this study. These "windows" of recruitment may be related to infrequent events that reduce the effects of land crabs. Our results suggest that unlike the context dependence of most keystone consumers in continental systems, a single consumer, the red land crab, consistently controls the dynamics of seedling recruitment across this island rainforest.

    Frugivory is a widespread mutualistic interaction in which frugivores obtain nutritional resources while favoring plant recruitment through their seed dispersal services. Nonetheless, how these complex interactions are organized in diverse communities, such as tropical forests, is not fully understood. In this study we evaluated the existence of plant-frugivore sub-assemblages and their phylogenetic organization in an undisturbed western Amazonian forest in Colombia. We also explored for potential keystone plants, based on network analyses and an estimate of the amount of fruit going from plants to frugivores. We carried out diurnal observations on 73 canopy plant species during a period of two years. During focal tree sampling, we recorded frugivore identity, the duration of each individual visit, and feeding rates. We did not find support for the existence of sub assemblages, such as specialized vs. generalized dispersal systems. Visitation rates on the vast majority of canopy species were associated with the relative abundance of frugivores, in which ateline monkeys (i.e. Lagothrix and Ateles) played the most important roles. All fruiting plants were visited by a variety of frugivores and the phylogenetic assemblage was random in more than 67% of the cases. In cases of aggregation, the plant species were consumed by only primates or only birds, and filters were associated with fruit protection and likely chemical content. Plants suggested as keystone species based on the amount of pulp going from plants to frugivores differ from those suggested based on network approaches. Our results suggest that in tropical forests most tree-frugivore interactions are generalized, and abundance should be taken into account when assessing the most important plants for frugivores.

  10. Identifying Keystone Species in the Human Gut Microbiome from Metagenomic Timeseries Using Sparse Linear Regression

    PubMed Central

    2014-01-01

    Human associated microbial communities exert tremendous influence over human health and disease. With modern metagenomic sequencing methods it is now possible to follow the relative abundance of microbes in a community over time. These microbial communities exhibit rich ecological dynamics and an important goal of microbial ecology is to infer the ecological interactions between species directly from sequence data. Any algorithm for inferring ecological interactions must overcome three major obstacles: 1) a correlation between the abundances of two species does not imply that those species are interacting, 2) the sum constraint on the relative abundances obtained from metagenomic studies makes it difficult to infer the parameters in timeseries models, and 3) errors due to experimental uncertainty, or mis-assignment of sequencing reads into operational taxonomic units, bias inferences of species interactions due to a statistical problem called “errors-in-variables”. Here we introduce an approach, Learning Interactions from MIcrobial Time Series (LIMITS), that overcomes these obstacles. LIMITS uses sparse linear regression with boostrap aggregation to infer a discrete-time Lotka-Volterra model for microbial dynamics. We tested LIMITS on synthetic data and showed that it could reliably infer the topology of the inter-species ecological interactions. We then used LIMITS to characterize the species interactions in the gut microbiomes of two individuals and found that the interaction networks varied significantly between individuals. Furthermore, we found that the interaction networks of the two individuals are dominated by distinct “keystone species”, Bacteroides fragilis and Bacteroided stercosis, that have a disproportionate influence on the structure of the gut microbiome even though they are only found in moderate abundance. Based on our results, we hypothesize that the abundances of certain keystone species may be responsible for individuality in the human

    Policy incoherence at the interface between trade policy and health can take many forms, such as international trade commitments that strengthen protection of pharmaceutical patents, or promotion of health tourism that exacerbates the shortage of physicians in rural areas. Focusing on the national policy-making process, we make recommendations regarding five conditions that are necessary, but not sufficient, to ensure that international trade policies are coherent with national health objectives. These conditions are: space for dialogue and joint fact-finding; leadership by ministries of health; institutional mechanisms for coordination; meaningful engagement with stakeholders; and a strong evidence base.

  14. [Mexican migration policies after IRCA].

    PubMed

    Alba, F

    1999-01-01

    The evolution since 1964 of Mexican government policy regarding migrant workers in the US is discussed. For a decade after the "bracero" program was terminated by the US, the Mexican government attempted to encourage creation of another legal framework for migration, regarded as inevitable whether legal or clandestine. Around 1974-75, a more distant attitude, termed the "policy of no policy," acquired considerable support in Mexican government and academic circles. The no-policy strategy allowed Mexico to achieve certain objectives regarding migration without prompting US intervention in its internal affairs, as for example by a linkage of US migration policy to specific Mexican government actions. The 1986 passage of the US Immigration Reform and Control Act effectively ended the no-policy strategy that had allowed the Mexican government to count on the continued emigration of Mexican workers without compromising its position of promoting respect for migrant rights. The unilateral change in the status quo by the US led to substitution of the "policy of dialogue," a clear signal of the Mexican government's search for a new migration agreement. The policy of dialogue has entailed greater discussion of the two traditional Mexican objectives regarding migration. Some progress has apparently been made concerning migrant rights, but the second and less explicit objective, that of preventing abrupt changes in US immigration policy and in migratory flows, is harder to judge. The atmosphere of freer public debate in Mexico is politicizing migratory policy.

    Community bioethics dialogues were held on the topic of patient-centered outcomes research (PCOR) and comparative effectiveness research (CER). Participants were 65 and older and represented either a lower income, African American group (A) or a higher income White group (B). Participants were presented with a variety of background reading and study materials. Meetings were held 2 hr per week for 6 weeks. The groups showed both independence in judgment from the investigators and diversity of opinion between the two groups. Group B addressed more topics than Group A and in some instances explored additional policy nuances. Members of Group A appeared more cognizant of issues of social justice that affect vulnerable populations and appeared leery of approaches that suggested possible disrespect for their own personal experiences. Future plans call for both repeating the dialogue with additional, diverse community groups and repeating community bioethics dialogues on new topics with the same groups.

  16. The palaeontological exhibition: a venue for dialogue.

    PubMed

    Murriello, Sandra

    2015-01-01

    Understanding the dialogue between museums and their visitors enables museums to subsist, undergo transformations and become consolidated as socially valued cultural venues. The Museo de La Plata (Argentina) was created in the late nineteenth century as a natural history museum, and this study shows that currently the museum is valued socially as a venue for family leisure and education, at which people make sense to the objects exhibited through characteristics conferred upon them by both the institution and the visitor. Nevertheless, such dialogue is somehow affected by the museographic proposal and the public interpretation of the institutional narrative, which could be analysed within the frame of contextual learning. As a consequence, the evolutionary idea that the museum aims to communicate is distorted by the public. This article highlights the importance of considering the visitors' interpretations when planning museum exhibitions, a perspective that has been rather absent in the Argentinian museums.

    A notion of asymmetric quantum dialogue (AQD) is introduced. Conventional protocols of quantum dialogue are essentially symmetric as the users (Alice and Bob) can encode the same amount of classical information. In contrast, the proposed scheme for AQD provides different amount of communication powers to Alice and Bob. The proposed scheme offers an architecture, where the entangled state to be used and the encoding scheme to be shared between Alice and Bob depend on the amount of classical information they want to exchange with each other. The general structure for the AQD scheme has been obtained using a group theoretic structure of the operators introduced in Shukla et al. (Phys Lett A 377:518, 2013). The effect of different types of noises (e.g., amplitude damping and phase damping noise) on the proposed scheme is investigated, and it is shown that the proposed scheme for AQD is robust and it uses an optimized amount of quantum resources.

    What do the behavior of monkeys in captivity and the financial system have in common? The nodes in such social systems relate to each other through multiple and keystone networks, not just one network. Each network in the system has its own topology, and the interactions among the system’s networks change over time. In such systems, the lead into a crisis appears to be characterized by a decoupling of the networks from the keystone network. This decoupling can also be seen in the crumbling of the keystone’s power structure toward a more horizontal hierarchy. This paper develops nonparametric methods for describing the joint model of the latent architecture of interconnected networks in order to describe this process of decoupling, and hence provide an early warning system of an impending crisis.

    2010-04-01

    Euphausiids are important components of many ecosystems, especially in productive regions of temperate and high latitudes. The present paper makes the case that E. mucronata plays a keystone role in the food web of the Humboldt Current System (HCS) based on a synthesis of new and published data supporting its potential role as a primary grazer, as well as a principal prey for upper trophic level fish. E. mucronata is an endemic species, concentrated in the coastal upwelling belt of the HCS, with morpho-physiological adaptations to vertically migrate into the Oxygen Minimum Zone (OMZ). Within the 100-km coastal belt of the HCS it accounts for ca. 50% of the meso zooplankton wet weight in winter. In the mixed layer, it is a herbivore with high night ingestion rates (612.2 ng Chl eq ind -1 h -1 or 1013.9 μg C ind -1 d -1, in winter), and accounted for a 19.3% impact on primary production in winter, at an intermediate population abundance (3.8 ind m -3). At higher abundances (50 ind m -3) equivalent to swarms, impact on primary production could reach 254%. Additionally E. mucronata is a common prey of numerous upper trophic level predators. The diet of jack mackerel ( Trachurus murphyi) off central Chile (34-39°S) indicates a striking dependence on E. mucronata prey (average of 75% of stomach content in weight). The fishing season off central Chile extended from austral fall (March-April) and continued at least until the end of austral winter (September). The average daily ration of jack mackerel was 17.4 g, which is equivalent to 2.3% of fish body weight per day. The total E. mucronata consumed in 1991 by the landed population of fish (3.7 million tons yr -1) amounted to 23.2 million tons yr -1. The total estimated population of jack mackerel that year (17.6 million tons) would have consumed ca. 110.2 million tons of E. mucronata. Based on stomach contents, consumption of E. mucronata by other nektonic predators off Chile and off Peru is also outstanding. Four

  2. Limited effects of a keystone species: Trends of sea otters and kelp forests at the Semichi Islands, Alaska

    Sea otters are well known as a keystone species because of their ability to transform sea urchin-dominated communities into kelp-dominated communities by preying on sea urchins and thus reducing the intensity of herbivory. After being locally extinct for more than a century, sea otters re-colonized the Semichi Islands in the Aleutian Archipelago, Alaska in the early 1990s. Here, otter populations increased to about 400 individuals by 1994, but rapidly declined to about 100 by 1997. Roughly 7 yr after initial otter re-colonization, there were only marginal changes in sea urchin biomass, mean maximum test size, and kelp density. These small changes may be the first steps in the cascading effects on community structure typically found with the invasion of a keystone species. However, no wholesale change in community structure occurred following re-colonization and growth of the sea otter population. Instead, this study describes a transition state and identifies factors such as keystone species density and residence time that can be important in dictating the degree to which otter effects are manifested.

  3. Structure of the active N-terminal domain of Ezrin. Conformational and mobility changes identify keystone interactions.

    Ezrin is a member of the ERM (ezrin, radixin, moesin) family of proteins that cross-link the actin cytoskeleton to the plasma membrane and also may function in signaling cascades that regulate the assembly of actin stress fibers. Here, we report a crystal structure for the free (activated) FERM domain (residues 2-297) of recombinant human ezrin at 2.3 A resolution. Structural comparison among the dormant moesin FERM domain structure and the three known active FERM domain structures (radixin, moesin, and now ezrin) allows the clear definition of regions that undergo structural changes during activation. The key regions affected are residues 135-150 and 155-180 in lobe F2 and residues 210-214 and 235-267 in lobe F3. Furthermore, we show that a large increase in the mobilities of lobes F2 and F3 accompanies activation, suggesting that their integrity is compromised. This leads us to propose a new concept that we refer to as keystone interactions. Keystone interactions occur when one protein (or protein part) contributes residues that allow another protein to complete folding, meaning that it becomes an integral part of the structure and would rarely dissociate. Such interactions are well suited for long-lived cytoskeletal protein interactions. The keystone interactions concept leads us to predict two specific docking sites within lobes F2 and F3 that are likely to bind target proteins.

    The application of required communication skills in the palliative dialogue necessitates a significant transition from the paternalistic medical approach to the holistic psychosocial approach that focuses on the patient and views the individual as a whole entity. Understanding the evolution of a therapeutic relationship in terms of entrance into the relationship, development, maintenance, and leave taking as well as the adoption of dialectical ideas gives palliative caregivers flexibility in the dialogue with patients and families. Accepting the principles of dialectics, in which the existence of contradictions is seen as an inherent part of a reality that is undergoing constant change, gives the caregiver the flexibility to interpret dichotomic thoughts and emotions as a dialectic failure and, in accordance, to move toward a synthesis of the ideas of living and dying. This approach provides caregivers the means to promote the palliative dialogue, implement varied communication skills to clarify the patient's goals, and implement a therapeutic plan to realize them.

    The issues related to tobacco harm reduction continue to challenge the tobacco control research and policy communities. The potential for combusting tobacco products to reduce exposure and risk remains largely unknown, but this has not stopped manufacturers from offering such products making these claims. The role of oral tobacco products in a harm reduction regimen has also been a source of dialogue and debate. Within the last few years, major cigarette manufacturing companies have begun selling smokeless products for the first time, claiming to target current cigarette smokers. Other cigarette manufacturers are also offering smokeless products in markets around the world. The harm reduction debate has at times been divisive. There has been no unifying set of principles or goals articulated to guide tobacco control efforts. In particular, the research needs are extraordinarily high in order to drive evidence-based policy in this area and avoid the mistakes made with “light” cigarettes. This paper discusses recommendations from a strategic dialogue held with key, mostly US-based tobacco control researchers and policy makers to develop a strategic vision and blueprint for research, policy and communications to reduce the harm from tobacco for the US. Short-term and long-term objectives are described. PMID:19240228

    Since the first documentation of climate-warming induced declines in arctic sea-ice, predictions have been made regarding the expected negative consequences for endemic marine mammals. But, several decades later, little hard evidence exists regarding the responses of these animals to the ongoing environmental changes. Herein, we report the first empirical evidence of a dramatic shift in movement patterns and foraging behaviour of the arctic endemic ringed seal (Pusa hispida), before and after a major collapse in sea-ice in Svalbard, Norway. Among other changes to the ice-regime, this collapse shifted the summer position of the marginal ice zone from over the continental shelf, northward to the deep Arctic Ocean Basin. Following this change, which is thought to be a 'tipping point', subadult ringed seals swam greater distances, showed less area-restricted search behaviour, dived for longer periods, exhibited shorter surface intervals, rested less on sea-ice and did less diving directly beneath the ice during post-moulting foraging excursions. In combination, these behavioural changes suggest increased foraging effort and thus also likely increases in the energetic costs of finding food. Continued declines in sea-ice are likely to result in distributional changes, range reductions and population declines in this keystone arctic species.

    The community of organisms inhabiting the water-filled leaves of the carnivorous pitcher-plant Sarracenia purpurea includes arthropods, protozoa and bacteria, and serves as a model system for studies of food web dynamics. Despite the wealth of data collected by ecologists and zoologists on this food web, very little is known about the bacterial assemblage in this microecosystem. We used terminal restriction fragment length polymorphism (T-RFLP) analysis to quantify bacterial diversity within the pitchers as a function of pitcher size, pH of the pitcher fluid and the presence of the keystone predator in this food web, larvae of the pitcher-plant mosquito Wyeomyia smithii. Results were analysed at two spatial scales: within a single bog and across three isolated bogs. Pitchers were sterile before they opened and composition of the bacterial assemblage was more variable between different bogs than within bogs. Measures of bacterial richness and diversity were greater in the presence of W. smithii and increased with increasing pitcher size. Our results suggest that fundamental ecological concepts derived from macroscopic food webs can also be used to predict the bacterial assemblages in pitcher plants.

    Rapid development and urbanization in recent years have contributed to a reduction in freshwater discharge and intensified saltwater intrusion in the Pearl River Delta. This comprises a significant threat to potable water supplies and overall estuary ecosystem health. In this study, the environmental flows of the Modaomen Estuary, one of the estuaries of the Pearl River Delta in China, were determined based on the salinity demand of keystone species and the linear relationship between river discharge and estuarine salinity. The estimated minimum and optimal annual environmental flows in the Modaomen Estuary were 116.8 × 109 m3 and 273.8 × 109 m3, respectively, representing 59.3% and 139.0% of the natural runoff. Water quality assessments in recent years indicate that the environmental flows have not been satisfied most of the time, particularly the optimal environmental flow, despite implementation of various water regulations since 2005. Therefore, water regulations and wetland network recoveries based on rational environmental flows should be implemented to alleviate saltwater intrusion and for the creation of an ideal estuarine habitat.

    Alien predators can have catastrophic effects on ecosystems and are thought to be much more harmful to biodiversity than their native counterparts. However, trophic cascade theory and the mesopredator release hypothesis predict that the removal of top predators will result in the reorganization of trophic webs and loss of biodiversity. Using field data collected throughout arid Australia, we provide evidence that removal of an alien top-predator, the dingo, has cascading effects through lower trophic levels. Dingo removal was linked to increased activity of herbivores and an invasive mesopredator, the red fox (Vulpes vulpes), and to the loss of grass cover and native species of small mammals. Using species distribution data, we predict that reintroducing or maintaining dingo populations would produce a net benefit for the conservation of threatened native mammals across greater than 2.42 x 10(6) km(2) of Australia. Our study provides evidence that an alien top predator can assume a keystone role and be beneficial for biodiversity conservation, and also that mammalian carnivores more generally can generate strong trophic cascades in terrestrial ecosystems.

    2009-09-22

    We report a mechanism of crypsis present during the vulnerable early post-metamorphic ontogeny (keystone predator characteristic of the southeastern Pacific coast. In the field, we found a significant occurrence (>95%) of specimens bearing patterns of shell coloration (dark or light colored) that matched the background coloration provided by patches of Concholepas' most abundant prey (mussels or barnacles respectively). The variation in shell color was positively associated with the color of the most common prey (r = 0.99). In laboratory experiments, shell coloration of C. concholepas depended on the prey-substrate used to induce metamorphosis and for the post-metamorphic rearing. The snail shell color matched the color of the prey offered during rearing. Laboratory manipulation experiments, switching the prey during rearing, showed a corresponding change in snail shell color along the outermost shell edge. As individuals grew and became increasingly indistinguishable from the surrounding background, cryptic individuals had higher survival (71%) than the non cryptic ones (4%) when they were reared in the presence of the predatory crab Acanthocyclus hassleri. These results suggest that the evolution of shell color plasticity during the early ontogeny of C. concholepas, depends on the color of the more abundant of the consumed prey available in the natural habitat where settlement has taken place; this in turn has important consequences for their fitness and survivorship in the presence of visual predators.

    Droughts are increasing in severity and frequency, yet the mechanisms that strengthen ecosystem resilience to this stress remain poorly understood. Here, we test whether positive interactions in the form of a mutualism between mussels and dominant cordgrass in salt marshes enhance ecosystem resistance to and recovery from drought. Surveys spanning 250 km of southeastern US coastline reveal spatially dispersed mussel mounds increased cordgrass survival during severe drought by 5- to 25-times. Surveys and mussel addition experiments indicate this positive effect of mussels on cordgrass was due to mounds enhancing water storage and reducing soil salinity stress. Observations and models then demonstrate that surviving cordgrass patches associated with mussels function as nuclei for vegetative re-growth and, despite covering only 0.1–12% of die-offs, markedly shorten marsh recovery periods. These results indicate that mutualisms, in supporting stress-resistant patches, can play a disproportionately large, keystone role in enhancing ecosystem resilience to climatic extremes.

    The bacterial and archaeal community composition and the possible carbon assimilation processes and energy sources of microbial communities in oligotrophic, deep, crystalline bedrock fractures is yet to be resolved. In this study, intrinsic microbial communities from six fracture zones from 180-2300 m depths in Outokumpu bedrock were characterized using high-throughput amplicon sequencing and metagenomic prediction. Comamonadaceae-, Anaerobrancaceae- and Pseudomonadaceae-related OTUs form the core community in deep crystalline bedrock fractures in Outokumpu. Archaeal communities were mainly composed of Methanobacteraceae-affiliating OTUs. The predicted bacterial metagenomes showed that pathways involved in fatty acid and amino sugar metabolism were common. In addition, relative abundance of genes coding the enzymes of autotrophic carbon fixation pathways in predicted metagenomes was low. This indicates that heterotrophic carbon assimilation is more important for microbial communities of the fracture zones. Network analysis based on co-occurrence of OTUs revealed the keystone genera of the microbial communities belonging to Burkholderiales and Clostridiales. Bacterial communities in fractures resemble those found from oligotrophic, hydrogen-enriched environments. Serpentinization reactions of ophiolitic rocks in Outokumpu assemblage may provide a source of energy and organic carbon compounds for the microbial communities in the fractures. Sulfate reducers and methanogens form a minority of the total microbial communities, but OTUs forming these minor groups are similar to those found from other deep Precambrian terrestrial bedrock environments.

    Aristida stricta Michx. (Poaceae) is a perennial bunchgrass native to the Southeastern Coastal Plain of North America where it is a keystone species in the longleaf pine savannas and slash pine flatwoods from southeastern North Carolina to Florida, and westward to the coast of Mississippi. We examined genetic relationships within and among ten populations of A. stricta by using eight inter-simple sequence repeat (ISSR) markers to generate band frequency data for 32 individuals from each sampled population. An analysis of molecular variance showed that 38% of the variation resided among populations while 62% was attributable to variation within populations. Grouping the populations by habitat or by geographic location did not show significant differentiation between the groups. Overall, pair-wise geographic and genetic distances were not correlated. Data indicate that while individuals within each population are genetically diverse, there seemingly are barriers to gene flow across populations leading to their divergence. Each population contains several exclusive loci suggesting that limited gene flow and/or genetic drift are likely leading to this pattern of localization. Our results, coupled with those of the previous studies that presented evidence for local adaptation and phenotypic differences among populations, suggest that there is sufficient differentiation among populations of this species to warrant: (1) maintenance of the existing genetic diversity at individual sites, and (2) use of local seed and plant sources for conservation projects.

    In this paper I focus on the transition from everyday to scientific ways of reasoning, and on the intertwined roles of meaning-making dialogue and science content as they contribute to scientific literacy. I refer to views of science, and how scientific understanding is advanced dialogically, by Hurd (Science Education, 1998, 82, 402-416), Brown (The Journal of Learning Sciences, 1992, 2(2), 141-178), Bruner (Acts of Meaning, Cambridge, MA: Harvard University Press, 1990), Roth (In J. Brophy (Ed.), Social Constructivist Teaching: Affordances and Constraints (Advances in Research on Teaching Series, Vol. 9), New York: Elsevier/JAI, 2003), and Wells (Dialogic Inquiry: Towards a Sociocultural Practice and Theory of Education, New York: Cambridge University Press, 1999). I argue that family collaborative dialogues in nonschool settings can be the foundations for scientific ways of thinking. I focus on the particular reflective family dialogues at the Monterey Bay Aquarium, when family members remembered and synthesized essential biological themes, centering on adaptation, from one visit to the next, in both Spanish and English. My approach is informed by sociocultural theory, with emphasis on the negotiations of meaning in the zone of proximal development (Vygotsky, 1978), as learners engage in joint productive activity (Tharp & Gallimore, Rousing Minds to Life: Teaching, Learning and Schooling in Social Context, New York: Cambridge University Press, 1988). Over the past decades, researchers have discovered that observing social activity, conversation, and meaning-making in informal settings (Crowley & Callanan, 1997; Guberman, 2002; Rogoff, 2001; Vasquez, Pease-Alvarez, & Shannon, Pushing Boundaries: Language and Culture in a Mexicano Community, New York: Cambridge University Press, 1994) has much to teach us regarding learning in general.

    Dialogue about complex science and society issues is important for contemporary conservation agendas. Conferences provide an appropriate space for such dialogue, but despite its recognized worth, best practices for facilitating active dialogue are still being explored. Face-to-face (FTF) and computer-mediated communication (CMC) are two approaches to facilitating dialogue that have different strengths. We assessed the use of these approaches to create dialogue on cultural perspectives of conservation and biodiversity at a national ecology conference. In particular, we aimed to evaluate their potential to enhance dialogue through their integrated application. We used an interactive blog to generate CMC on participant-sourced issues and to prime subsequent discussion in an FTF conference workshop. The quantity and quality of both CMC and FTF discussion indicated that both approaches were effective in building dialogue. Prior to the conference the blog averaged 126 views per day, and 44 different authors contributed a total of 127 comments. Twenty-five participants subsequently participated in active FTF discussion during a 3-h workshop. Postconference surveys confirmed that CMC had developed participants' thinking and deepened FTF dialogue; 88% indicated specifically that CMC helped facilitate the FTF discussion. A further 83% of respondents concluded that preliminary blog discussion would be useful for facilitating dialogue at future conferences.

Along with cultivation, the river was channelized and dammed to prevent flooding and to stabilize the Mexico/U.S. border.The loss of wetland ecosystems in the area changed migration patterns of water fowl and destroyed priceless aquatic habitats.The area of our study, Keystone Heritage Park, is the last remaining open wetlands in El Paso County. Before efforts of restoration to reestablish wetlands associated with the Rio Grande can begin, there must be an in-depth, and complete, understanding of the surface and subsurface hydrological system which created and sustains this last remaining wetland. Studies of the wetland's soil properties and their effect on groundwater flow have indicated regions on the periphery of the wetlands where soils are saturated with moisture.These subsurface regions of saturated soils are semi-linear in shape and lead toward the wetland indicating that they are possible loci for groundwater flow for the wetland.These subsurface soil layers are possibly composed of mountain front alluvium that is being feed with meteoric water entering faults that bound the nearby Franklin Mountains.The primary goals of this study are 1) initiate a systematic data acquisition from 9 piezometers and 2 water level loggers of temporal variations in the depth of the groundwater due to regional pumping or rain fall and 2) generate a depth and TDS (Total Dissolved Solids) profile of the wetland pond to locate regions where groundwater maybe entering the lake.

    Changes in temperature have occurred throughout Earth's history. However, current warming trends exacerbated by human activities impose severe and rapid loss of biodiversity. Although understanding the mechanisms orchestrating organismal response to climate change is important, remarkably few studies document their role in nature. This is because only few systems enable the combined analysis of genetic and plastic responses to environmental change over long time-spans. Here, we characterize genetic and plastic responses to temperature increase in the aquatic keystone grazer Daphnia magna combining a candidate gene and an outlier analysis approach. We capitalize on the short generation time of our species, facilitating experimental evolution, and the production of dormant eggs enabling the analysis of long term response to environmental change through a resurrection ecology approach. We quantify plasticity in the expression of 35 candidate genes in D. magna populations resurrected from a lake that experienced changes in average temperature over the past century and from experimental populations differing in thermal tolerance isolated from a selection experiment. By measuring expression in multiple genotypes from each of these populations in control and heat treatments we assess plastic responses to extreme temperature events. By measuring evolutionary changes in gene expression between warm and cold adapted populations we assess evolutionary response to temperature changes. Evolutionary response to temperature increase is also assessed via an outlier analysis using EST-linked microsatellite loci. This study provides the first insights into the role of plasticity and genetic adaptation in orchestrating adaptive responses to environmental change in D. magna This article is protected by copyright.

    Anthropogenic climate change poses a serious threat to biodiversity. In marine environments, multiple climate variables, including temperature and CO2 concentration ([CO2]), are changing simultaneously. Although temperature has well-documented ecological effects, and many heavily calcified marine organisms experience reduced growth with increased [CO2], little is known about the combined effects of temperature and [CO2], particularly on species that are less dependent on calcified shells or skeletons. We manipulated water temperature and [CO2] to determine the effects on the sea star Pisaster ochraceus, a keystone predator. We found that sea star growth and feeding rates increased with water temperature from 5 °C to 21 °C. A doubling of current [CO2] also increased growth rates both with and without a concurrent temperature increase from 12 °C to 15 °C. Increased [CO2] also had a positive but nonsignificant effect on sea star feeding rates, suggesting [CO2] may be acting directly at the physiological level to increase growth rates. As in past studies of other marine invertebrates, increased [CO2] reduced the relative calcified mass in sea stars, although this effect was observed only at the lower experimental temperature. The positive relationship between growth and [CO2] found here contrasts with previous studies, most of which have shown negative effects of [CO2] on marine species, particularly those that are more heavily calcified than P. ochraceus. Our findings demonstrate that increased [CO2] will not have direct negative effects on all marine invertebrates, suggesting that predictions of biotic responses to climate change should consider how different types of organisms will respond to changing climatic variables.

  16. Estaurine Freshwater Entrainment By Oyster Reefs: Quantifying A Keystone Ecosystem Service

    Oyster reefs have been shown to provide myriad critical ecosystem services, however their role in directing flow and currents during non-storm conditions has been largely neglected. In many regions, oyster reefs form as linear structures perpendicular to the coast and across the path of streams and rivers, potentially entraining large volumes of freshwater flow and altering nearshore mixing. We hypothesize that these reefs have the potential to influence salinity over large areas, providing a "keystone" ecosystem service by supporting multiple estuarine functions. Here we present results from a field and modeling study to quantify the effects of reef extent and elevation on estuarine salinities under varying river discharge. We found salinity differences ranging from 2 to 16 g/kg between inshore and offshore sides of degraded oyster reefs in the Suwannee Sound (FL, USA), supporting the role of reefs as local-scale freshwater dams. Moreover, differences between inshore and offshore salinities were correlated with flow, with the most marked differences during periods of low flow. Hydrodynamic modeling using the 3-D Regional Ocean Modeling System (ROMS) suggests that the currently degraded reef system entrained greater volumes of freshwater in the past, buffering the landward advance of high salinities, particularly during low flow events related to droughts. Using ROMS, we also modeled a variety of hypothetical oyster bar morphology scenarios (historical, current, and "restored") to understand how changes in reef structure (elevation, extent, and completeness) impact estuarine mixing and near-shore salinities. Taken together, these results serve to: 1) elucidate a poorly documented ecosystem service of oyster reefs; 2) provide an estimate of the magnitude and sptial extent of the freshwater entrainment effect; and 3) offer quantitative information to managers and restoration specialists interested in restoring oyster habitat.

  17. Fostering climate dialogue by introducing students to uncertainty in decision-making

    Uncertainty is present in all fields of climate research, spanning from climate projections, to assessing regional impacts and vulnerabilities to adaptation policy and decision-making. The complex and interdisciplinary nature of climate information, however, makes the decision-making process challenging. This process is further hindered by a lack of institutionalized dialogue between climate researchers, decision-makers and user groups. Forums that facilitate such dialogue would allow these groups to actively engage with each other to improve decisions. In parallel, introducing students to these challenges is one way to foster such climate dialogue. We present the design and outcome of an innovative workshop-seminar series we convened at the University of Zurich to demonstrate the pedagogical importance of such forums. An initial two-day workshop brought together 50 participants, including bachelor, master and PhD students and academic staff, and nine speakers from academia, industry, government, and philanthropy. The main objectives were to provide participants with tools to communicate uncertainty in their current or future research projects, to foster exchange between practitioners, students and scientists from different backgrounds and finally to expose students to multidisciplinary collaborations and real-world problems involving decisions under uncertainty. An opinion survey conducted before and after the workshop enabled us to observe changes in participants' perspectives on what information and tools should be exchanged between researchers and decision-makers to better address uncertainty. Responses demonstrated a marked shift from a pre-workshop vertical conceptualization of researcher-user group interaction to a post-workshop horizontal mode: in the former, researchers were portrayed as bestowing data-based products to decision-makers, while in the latter, both sets of actors engaged in frequent communication, exchanging their needs and expertise.

    2005-01-01

    In this article, the authors offer a solution to a phenomenon identified as "silencing" among nurse colleagues during national, regional, and international scholarly conferences. Through an electronic anonymous survey, data were collected regarding perceptions of the structure and process at scholarly nursing conferences. The need for critique and dialogue while sharing research ideas or findings is identified as a means to encourage direct exchange at professional conferences. Based on an examination of the process of critique and dialogue, and theories that explain why honest and direct dialogue are sometimes subdued, the authors propose a model of constructive scholarly dialogue for conference participation. The goals of implementing this model are to make scholarly exchanges normative at nursing conferences, and to revise standard conference formats so that constructive critique and dialogue are encouraged actively. The likely outcomes include improved nursing science and professional development of nurses.

    2013-01-01

    Heterosexism contributes to an unsafe campus climate for lesbian, gay, and bisexual (LGB) college students. Intergroup dialogue courses about sexual orientation seek to build awareness, cross-group relationships, and commitment to social action to address anti-LGB prejudice and discrimination. Although dialogue courses are growing in popularity, few courses address sexual orientation. To advance knowledge of these dialogues, this qualitative study explores heterosexual students' motivations and expectations, challenges, and learning outcomes related to their participation in intergroup dialogue courses on sexual orientation. Core themes include desire to learn about the LGB community, concerns about offending classmates, anxiety around LGB stigma, conflict with classmates around controversial topics, affirming LGB people, and learning about heterosexism, privilege, and intersectionality of identity. Implications for intergroup dialogue pedagogy and research are discussed.

  20. Disfluency in dialogue: an intentional signal from the speaker?

    PubMed

    Finlayson, Ian R; Corley, Martin

    2012-10-01

    Disfluency is a characteristic feature of spontaneous human speech, commonly seen as a consequence of problems with production. However, the question remains open as to why speakers are disfluent: Is it a mechanical by-product of planning difficulty, or do speakers use disfluency in dialogue to manage listeners' expectations? To address this question, we present two experiments investigating the production of disfluency in monologue and dialogue situations. Dialogue affected the linguistic choices made by participants, who aligned on referring expressions by choosing less frequent names for ambiguous images where those names had previously been mentioned. However, participants were no more disfluent in dialogue than in monologue situations, and the distribution of types of disfluency used remained constant. Our evidence rules out at least a straightforward interpretation of the view that disfluencies are an intentional signal in dialogue.

    The dispersal capacity of plant species that rely on animals to disperse their seeds (biotic dispersal) can alter with changes to the populations of their keystone dispersal vectors. Knowledge on how biotic dispersal systems vary across landscapes allows better understanding of factors driving plant persistence. Myrmecochory, seed dispersal by ants, is a common method of biotic dispersal for many plant species throughout the world. We tested if the seed dispersal system of Acacia terminalis (Fabaceae), a known myrmecochore, differed between two elevations in the Greater Blue Mountains World Heritage Area, in southeastern Australia. We compared ant assemblages, seed removal rates of ants and other vertebrates (bird and mammal) and the dominant seed-dispersing ant genera. At low elevations (c. 200 m a.s.l) seed removal was predominantly by ants, however, at high elevation sites (c. 700 m a.s.l) vertebrate seed dispersers or seed predators were present, removing over 60% of seeds from experimental depots when ants were excluded. We found a switch in the keystone seed-dispersing ant genera from Rhytidoponera at low elevations sites to Aphaenogaster at high elevation sites. This resulted in more seeds being removed faster at low elevation sites compared to high elevation sites, however long-term seed removal rates were equal between elevations. Differences in the keystone seed removalist, and the addition of an alternate dispersal vector or seed predator at high elevations, will result in different dispersal and establishment patterns for A. terminalis at different elevations. These differences in dispersal concur with other global studies that report myrmecochorous dispersal systems alter with elevation.

    2007-01-01

    Spoken dialogue systems have been increasingly employed to provide ubiquitous automated access via telephone to information and services for the non-Internet-connected public. In the health care context, dialogue systems have been successfully applied. Nevertheless, speech-based technology is not easy to implement because it requires a considerable development investment. The advent of VoiceXML for voice applications contributed to reduce the proliferation of incompatible dialogue interpreters, but introduced new complexity. As a response to these issues, we designed an architecture for dialogue representation and interpretation, AdaRTE, which allows developers to layout dialogue interactions through a high level formalism that offers both declarative and procedural features. AdaRTE aim is to provide a ground for deploying complex and adaptable dialogues whilst allows the experimentation and incremental adoption of innovative speech technologies. It provides the dynamic behavior of Augmented Transition Networks and enables the generation of different backends formats such as VoiceXML. It is especially targeted to the health care context, where a framework for easy dialogue deployment could reduce the barrier for a more widespread adoption of dialogue systems.

    Legal, procedural, and institutional restrictions on safe abortion services-such as laws forbidding the practice or policies preventing donors from supporting groups who provide legal services-remain a major access barrier for women worldwide. However, even when abortion services are legal, women face social and cultural barriers to accessing safe abortion services and preventing unwanted pregnancy. Interpersonal communication interventions play an important role in overcoming these obstacles, including as part of broad educational- and behavioral-change efforts. This article presents results from an interpersonal communication behavior change pilot intervention, Dialogues for Life, undertaken in Nepal from 2004 to 2006, after abortion was legalized in 2002. The project aimed to encourage and enable women to prevent unplanned pregnancies and unsafe abortions and was driven by dialogue groups and select community events. The authors' results confirm that a dialogue-based interpersonal communication intervention can help change behavior and that this method is feasible in a low-resource, low-literacy setting. Dialogue groups play a key role in addressing sensitive and stigmatizing health issues such as unsafe abortion and in empowering women to negotiate for the social support they need when making decisions about their health.

    In response to Shady's reflection on his experience as a teacher-researcher in which he explored different cogen structures, we consider fluid participant configurations using cogens as a research method to provide insights into classroom life. Our cogens illuminated the role of symbolic, cultural and social capital in student-teacher alignments that changed across different classroom situations. In Shady's study, as well as our own, respectful student-teacher relationships that involved the teacher and students first establishing common social capital, enabled the teacher to "be in with" the students, and vice versa. We raise questions about how the structure of cogens might affect the nature of the dialogue that is cogenerated.

    1993-12-01

    This article expands the dialogue on interpretive research methodology, locating this set of approaches within a broad historical and interdisciplinary context. Several of the most commonly held misconceptions in nursing, particularly those related to the meanings and derivations ascribed to "grounded theory," "symbolic interactionism," and "ethnography," are examined. The interpretive research approaches not only have gained broader acceptance across disciplines, but also have shifted in more radical and often less structured directions during the past decade. Several pivotal areas of these ongoing shifts are analyzed for their relevance to nursing research: the influence of critical and feminist theory and postmodernism, the ambiguity inherent in both every-day life and the research enterprise, the importance of locating the researcher, power and status inequities, the problematic aspects of language, meaning, and representation, and the emphasis on reflexivity and context as constitutive of meaning.

By means of interdisciplinary dialogue and research into elements that prove this presence, active participation and presence in the literature, an attempt was made to historicize these ties, not only of the poet from Itabira, but other men of letters, be they pharmaceutical professionals or people inspired by them. The objective was also to highlight some evidence that supports and demonstrates the importance of this professional in Brazilian society of the late-nineteenth century and early-twentieth century.

  13. Effects of groundwater abstraction on two keystone tree species in an arid savanna national park

    2017-01-01

    Background In arid systems with no surface water, deep boreholes in ephemeral river beds provide for humans and animals. With continually increasing infrastructure development for tourism in arid wildlife parks such as the Kgalagadi Transfrontier Park in southern Africa, we ask what effects increased abstraction may have on large trees. Large trees in arid savannas perform essential ecosystem services by providing food, shade, nesting sites and increased nutrients for many other plant and animal species and for this are regarded as keystone species. Methods We determine seasonal fluctuations in the water table while also determining the water source for the dominant large tree species in the Auob and Nossob rivers in the Park. We also determine the extent to which these trees are physiologically stressed using leaf δ13C, xylem pressure potentials, specific leaf area and an estimate of canopy death. We do this both upstream and downstream of a low water use borehole in the Auob River and a high water use borehole in the Nossob River. Results Our results show that the trees are indeed using deep groundwater in the wet season and that this is the same water used by people. In the dry season, trees in the Auob downstream of the active borehole become detached from the aquifer and use more isotopically enriched soil water. In the Nossob in the dry season, all trees use isotopically enriched soil water, and downstream of the active borehole use stomatal regulation to maintain leaf water potentials. These results suggest that trees in the more heavily utilised Nossob are under more water stress than those trees in the Auob but that trees in both rivers demonstrate physiological adaptation to the changes in available water with smaller heavier leaves, no significant canopy dieback and in the dry season in the Nossob stomatal regulation of leaf water potentials. Discussion An increase in abstraction of groundwater particularly at the Nossob borehole may cause an additional

    Hiking trails, which are among the most common forms of infrastructure created for nature-based tourism, can alter key ecological processes. Trails can damage plants that facilitate the establishment and growth of other species leading to changes in community and functional composition. This can be a particular concern in harsh alpine ecosystems where plant communities are often dominated by one or two keystone species that provide shelter to a suite of beneficiary species. We analysed how a hiking trail affects interspecific facilitation by a dominant trampling-sensitive nurse shrub in the highest National Park in Australia. First we assessed the effects of the trail on the abundance, size and density of the nurse shrub at different distances from the trail. We then compared species richness and composition between areas in, and out, of the nurse shrub's canopy at different distances from the trail. To better understand why some species may benefit from facilitation and any effects of the trail on the quality of facilitation we compared functional composition between quadrats using community trait weighted means calculated by combining plant composition with species functional traits (canopy height, leaf area, % dry weight of leaves and specific leaf area). The abundance, size and density of nurse shrubs was lower on the trail edges than further away, particularly on the leeward edge, where there was more bare ground and less shrub cover. There were differences in species richness, cover, composition and functional composition in and outside the nurse shrub canopy. The shrubs appeared to facilitate species with more competitive, but less stress tolerant traits (e.g. taller plants with leaves that were larger, had high specific leaf area and low dry matter content). However, despite reductions in nurse shrubs near the trail, where they do exist, they appear to provide the same 'quality' of facilitation as nurse shrubs further away. However, longer-term effects may

    Oil spills from pipeline ruptures are a major source of terrestrial petroleum pollution in cold regions. However, our knowledge of the bacterial response to crude oil contamination in cold regions remains to be further expanded, especially in terms of community shifts and potential development of hydrocarbon degraders. In this study we investigated changes of microbial diversity, population size and keystone taxa in permafrost soils at four different sites along the China-Russia crude oil pipeline prior to and after perturbation with crude oil. We found that crude oil caused a decrease of cell numbers together with a reduction of the species richness and shifts in the dominant phylotypes, while bacterial community diversity was highly site-specific after exposure to crude oil, reflecting different environmental conditions. Keystone taxa that strongly co-occurred were found to form networks based on trophic interactions, that is co-metabolism regarding degradation of hydrocarbons (in contaminated samples) or syntrophic carbon cycling (in uncontaminated samples). With this study we demonstrate that after severe crude oil contamination a rapid establishment of endemic hydrocarbon degrading communities takes place under favorable temperature conditions. Therefore, both endemism and trophic correlations of bacterial degraders need to be considered in order to develop effective cleanup strategies. PMID:27886221

    Habitat loss represents one of the main threats to tropical forests, which have reached extremely high rates of species extinction. Forest loss negatively impacts biodiversity, affecting ecological (e.g., seed dispersal) and genetic (e.g., genetic diversity and structure) processes. Therefore, understanding how deforestation influences genetic resources is strategic for conservation. Our aim was to empirically evaluate the effects of landscape-scale forest reduction on the spatial genetic structure and gene flow of Euterpe edulis Mart (Arecaceae), a palm tree considered a keystone resource for many vertebrate species. This study was carried out in nine forest remnants in the Atlantic Forest, northeastern Brazil, located in landscapes within a gradient of forest cover (19-83%). We collected leaves of 246 adults and 271 seedlings and performed genotyping using microsatellite markers. Our results showed that the palm populations had low spatial genetic structure, indicating that forest reduction did not influence this genetic parameter for neither seedlings nor adults. However, forest loss decreased the gene flow distance, which may negatively affect the genetic diversity of future generations by increasing the risk of local extinction of this keystone palm. For efficient strategies of genetic variability conservation and maintenance of gene flow in E. edulis, we recommend the maintenance of landscapes with intermediary to high levels of forest cover, that is, forest cover above 40%.

    Health literacy deficits affect half the American patient population and are linked to poor health, ineffective disease management and high rates of hospitalization. Restricted literacy has also been linked with less satisfying medical visits and communication difficulties, particularly in terms of the interpersonal and informational aspects of care. Despite growing attention to these issues by researchers and policy makers, few studies have attempted to conceptualize and assess those aspects of dialogue that challenge persons with low literacy skills, i.e., the oral literacy demand within medical encounters. The current study uses videotapes and transcripts of 152 prenatal and cancer pretest genetic counseling sessions recorded with simulated clients to develop a conceptual framework to explore oral literacy demand and its consequences for medical interaction and related outcomes. Ninety-six prenatal and 81 cancer genetic counselors-broadly representative of the US National Society of Genetic Counselors-participated in the study. Key elements of the conceptual framework used to define oral literacy demand include: (1) use of unfamiliar technical terms; (2) general language complexity, reflected in the application of Microsoft Word grammar summary statistics to session transcripts; and, (3) structural characteristics of dialogue, including pacing, density, and interactivity. Genetic counselor outcomes include self-ratings of session satisfaction, informativeness, and development of rapport. The simulated clients rated their satisfaction with session communication, the counselor's effective use of nonverbal skills, and the counselor's affective demeanor during the session. Sessions with greater overall technical term use were longer and used more complex language reflected in readability indices and multi-syllabic vocabulary (measures averaging p<.05). Sessions with a high proportionate use of technical terms were characterized by shorter visits, high readability

    Intergroup dialogue is a method of social justice education. Most intergroup dialogue research explores race and gender identities. Sexual orientation dialogues are uncommon and not yet examined empirically. This qualitative study explores sexual orientation dialogue courses from the perspective of lesbian, gay, and bisexual (LGB) student participants. Understanding target, or marginalized, group perspective of planned intergroup experiences is important given concerns raised in the literature. We document student motivations for participating in dialogues, core outcomes, and main challenges that arose in dialogue. Core outcomes include learning about and accepting one's sexual identity and empowerment. Challenges include those stemming from invisibility of sexual orientation identity. Recommendations are made for intergroup dialogue practice and research.

    2015-12-01

    This presentation will describe a collaborative dialogue process between earth scientists and emergency management officials that focused on translation of science into policy, building long term trust based relationships between sectors and unified presentation of hazards, risks and consequence management to public officials and the general public. The author will describe the structure and process of the California Earthquake Prediction Evaluation Council (CEPEC) in assessing the credibility of long and short term earthquake predictions, assessment of risk, and the formulation of public communication strategies and preparatory actions by government agencies. For nearly 4 decades, earth scientists, politically appointed state officials and emergency managers have engaged in ongoing discussions of the policy implications of research on potential seismic risk. Some discussions were scheduled and occurred over months, and others were ad hoc and occurred in the minutes between potential precursory incidents and possible large events. The effectiveness of this process was dependent on building respect for ones counterparts expertise, bias and responsibilities, clear communication of data, uncertainty and knowledge of the physical models assumed, history and probabilities; and the physical and political consequences of possible events; and the costs and economic and social disruption of alternative preparedness actions. But, the dialogue included political and social scientists, representatives of the print and broadcast media, political and management officials from federal, state and local governments. The presentation will provide an assessment of the effectiveness of the collaborative dialogue process and lessons on sustaining a long term partnership among the participating federal, state and local officials.

    In order to broaden the public dialogue about climate change, climate scientists need to leverage the potential of informal science education and recent advances in social and cognitive science. In the US, more than 1,500 informal science venues (science centers, museums, aquariums, zoos, nature centers, national parks, etc.) are visited annually by 61% of the population. Extensive research shows that these visitors are receptive to learning about climate change and trust these institutions as reliable sources. Given that we spend less than 5% of our lifetime in a classroom, and only a fraction of that is focused on science, informal science venues will continue to play a critical role in shaping public understanding of environmental issues in the years ahead. Public understanding of climate change continues to lag far behind the scientific consensus not merely because the public lacks information, but because there is in fact too much complex and contradictory information available. Fortunately, we can now (1) build on careful empirical cognitive and social science research to understand what people already value, believe, and understand; and then (2) design and test strategies for translating complex science so that people can examine evidence, make well-informed inferences, and embrace science-based solutions. The New England Aquarium is leading a national effort to enable informal science education institutions to effectively communicate the impacts of climate change and ocean acidification on marine ecosystems. This NSF-funded partnership, the National Network for Ocean and Climate Change Interpretation (NNOCCI), involves the Association of Zoos and Aquariums, FrameWorks Institute, Woods Hole Oceanographic Institution, Monterey Bay Aquarium, and National Aquarium, with evaluation conducted by the New Knowledge Organization, Pennsylvania State University, and Ohio State University. We believe that skilled interpreters can serve as "communication strategists" by

    There are many kinds of so-called irregular expressions in natural dialogues. Even if the content of a conversation is the same in words, different meanings can be interpreted by a person's feeling or face expression. To have a good understanding of dialogues, it is required in a flexible dialogue processing system to infer the speaker's view properly. However, it is difficult to obtain the meaning of the speaker's sentences in various scenes using traditional methods. In this paper, a new approach for dialogue processing that incorporates information from the speaker's face is presented. We first divide conversation statements into several simple tasks. Second, we process each simple task using an independent processor. Third, we employ some speaker's face information to estimate the view of the speakers to solve ambiguities in dialogues. The approach presented in this paper can work efficiently, because independent processors run in parallel, writing partial results to a shared memory, incorporating partial results at appropriate points, and complementing each other. A parallel algorithm and a method for employing the face information in a dialogue machine translation will be discussed, and some results will be included in this paper.

    The Keystone Sanitation Landfill site is a former farm which began receiving municipal waste and industrial construction debris in September 1966. The still active site is situated on a ridge, and runoff leaves the site from all directions. The environmental contamination on-site consists of 1,1,1-trichloroethane, trichloroethylene, vinyl chloride, benzene, 1,1-dichloroethane, 1,1-dichloroethylene, tetrachloroethylene, trans-1,2-dichloroethylene, chromium, lead, and N-nitrosodiphenylamine in groundwater. The environmental contamination off-site consists of tetrachloroethylene, 1,1,1-trichloroethane, 1,1-dichloroethylene, 1,1-dichloroethane, trichloroethylene in surface water; and lead, vinyl chloride, and 1,2-dichloroethylene in private wells. The site is considered to be of potential public health concern because of the risk to human health caused by the possibility of exposure to hazardous substances via groundwater, soil, and surface water.

    Demographic processes exert different degrees of control as individuals grow, and in species that span several habitats and spatial scales, this can influence our ability to predict their population at a particular life-history stage given the previous life stage. In particular, when keystone species are involved, this relative coupling between demographic stages can have significant implications for the functioning of ecosystems. We examined benthic and pelagic abundances of the sea urchin Paracentrotus lividus in order to: 1) understand the main life-history bottlenecks by observing the degree of coupling between demographic stages; and 2) explore the processes driving these linkages. P. lividus is the dominant invertebrate herbivore in the Mediterranean Sea, and has been repeatedly observed to overgraze shallow beds of the seagrass Posidonia oceanica and rocky macroalgal communities. We used a hierarchical sampling design at different spatial scales (100 s, 10 s and <1 km) and habitats (seagrass and rocky macroalgae) to describe the spatial patterns in the abundance of different demographic stages (larvae, settlers, recruits and adults). Our results indicate that large-scale factors (potentially currents, nutrients, temperature, etc.) determine larval availability and settlement in the pelagic stages of urchin life history. In rocky macroalgal habitats, benthic processes (like predation) acting at large or medium scales drive adult abundances. In contrast, adult numbers in seagrass meadows are most likely influenced by factors like local migration (from adjoining rocky habitats) functioning at much smaller scales. The complexity of spatial and habitat-dependent processes shaping urchin populations demands a multiplicity of approaches when addressing habitat conservation actions, yet such actions are currently mostly aimed at managing predation processes and fish numbers. We argue that a more holistic ecosystem management also needs to incorporate the landscape

    2016-04-01

    The following article presents basic concepts and methods of Ragnar Rommetveit's (born 1924) hermeneutic-dialogical approach to everyday spoken dialogue with a focus on both shared consciousness and linguistically mediated meaning. He developed this approach originally in his engagement of mainstream linguistic and psycholinguistic research of the 1960s and 1970s. He criticized this research tradition for its individualistic orientation and its adherence to experimental methodology which did not allow the engagement of interactively established meaning and understanding in everyday spoken dialogue. As a social psychologist influenced by phenomenological philosophy, Rommetveit opted for an alternative conceptualization of such dialogue as a contextualized, partially private world, temporarily co-established by interlocutors on the basis of shared consciousness. He argued that everyday spoken dialogue should be investigated from within, i.e., from the perspectives of the interlocutors and from a psychology of the second person. Hence, he developed his approach with an emphasis on intersubjectivity, perspectivity and perspectival relativity, meaning potential of utterances, and epistemic responsibility of interlocutors. In his methods, he limited himself for the most part to casuistic analyses, i.e., logical analyses of fictitious examples to argue for the plausibility of his approach. After many years of experimental research on language, he pursued his phenomenologically oriented research on dialogue in English-language publications from the late 1980s up to 2003. During that period, he engaged psycholinguistic research on spoken dialogue carried out by Anglo-American colleagues only occasionally. Although his work remained unfinished and open to development, it provides both a challenging alternative and supplement to current Anglo-American research on spoken dialogue and some overlap therewith.

    A combination platform-debate session was held at the Society of Environmental Toxicology and Chemistry (SETAC) North America annual meeting in Boston (November 2011). The session was organized by members of the Advisory Group on Sustainability, newly formed and approved as a global entity by the SETAC World Council just prior to the meeting. The platform portion of the session provided a historical backdrop for the debate that was designed to explore SETAC's role in the sustainability dialogue. The debate portion presented arguments for and against the proposition that "Science is the primary contribution of SETAC to the global dialogue on sustainability." Although the debate was not designed to achieve a definitive sustainability policy for SETAC, the audience clearly rejected the proposition, indicating a desire from the SETAC membership for an expanded role in global sustainability forums. This commentary details the key elements of the session, identifies the contribution the Advisory Group will have at the World Congress in Berlin (May 2012), and invites interested persons to become active in the Advisory Group.

    Three studies investigated the effects of presentation modality and redundancy of verbal content on recognition memory for entertainment film dialogue. U.S. participants watched two brief movie clips and afterward answered multiple-choice questions about information from the dialogue. Experiment 1 compared recognition memory for spoken dialogue in the native language (English) with subtitles in English, French, or no subtitles. Experiment 2 compared memory for material in English subtitles with spoken dialogue in English, French, or no sound. Experiment 3 examined three control conditions with no spoken or captioned material in the native language. All participants watched the same video clips and answered the same questions. Performance was consistently good whenever English dialogue appeared in either the subtitles or sound, and best of all when it appeared in both, supporting the facilitation of verbal redundancy. Performance was also better when English was only in the subtitles than when it was only spoken. Unexpectedly, sound or subtitles in an unfamiliar language (French) modestly improved performance, as long as there was also a familiar channel. Results extend multimedia research on verbal redundancy for expository material to verbal information in entertainment media.

It has provided a means of soliciting stakeholder input before key decisions are made. The projects developed under the ACWA Program are characterized as major federal actions and therefore also must meet the requirements of the National Environmental Policy Act (NEPA). One of these is the requirement for public participation in the environmental impact assessment process. This case study describes the ACWA Dialogue and NEPA processes, and examines their relationship in the implementation of the ACWA Program. The examination suggests that involving the public at the beginning of a program through a Dialogue-like process can introduce environmental considerations early in the project development process and contribute to the development of a more informed public. These factors improve the overall efficacy of public participation, strengthening the link between project development and environmental assessment in a manner consistent with the original intent of NEPA.

    Uncertainty is present in all fields of climate research, spanning from projections of future climate change, to assessing regional impacts and vulnerabilities, to adaptation policy and decision-making. In addition to uncertainties, managers and planners in many sectors are often confronted with large amounts of information from climate change research whose complex and interdisciplinary nature make it challenging to incorporate into the decision-making process. An overarching issue in tackling this problem is the lack of institutionalized dialogue between climate researchers, decision-makers and user groups. Forums that facilitate such dialogue would allow climate researchers to actively engage with end-users and researchers in different disciplines to better characterize uncertainties and ultimately understand which ones are critically considered and incorporated into decisions made. We propose that the introduction of students to these challenges at an early stage of their education and career is a first step towards improving future dialogue between climate researchers, decision-makers and user groups. To this end, we organized a workshop at the University of Zurich, Switzerland, entitled "Uncertainty in Decision Making in a Changing Climate". It brought together 50 participants, including Bachelor, Master and PhD students and academic staff, and nine selected speakers from academia, industry, government, and philanthropy. Speakers introduced participants to topics ranging from uncertainties in climate model scenarios to managing uncertainties in development and aid agencies. The workshop consisted of experts' presentations, a panel discussion and student group work on case studies. Pedagogical goals included i) providing participants with an overview of the current research on uncertainty and on how uncertainty is dealt with by decision-makers, ii) fostering exchange between practitioners, students, and scientists from different backgrounds, iii) exposing

    Embodied Conversational Agents (ECA) are poised to constitute a specific category within persuasive systems, in particular through their ability to support affective dialogue. One possible approach consists in using ECA as virtual coaches or personal assistants and to make persuasion part of a dialogue game implementing specific argumentation or negotiation features. In this paper, we explore an alternative framework, which emerges from the long-term development of ECA as "Companions" supporting free conversation with the user, rather than task-oriented dialogue. Our system aims at influencing user attitudes as part of free conversation, albeit on a limited set of topics. We describe the implementation of a Companion ECA to which the user reports on his working day, and which can assess the user's emotional attitude towards daily events in the office, trying to influence such attitude using affective strategies derived from a narrative model. This discussion is illustrated through examples from a first fully-implemented prototype.

    Critically reflective dialogues (CRD) are important for knowledge sharing and creating meaning in communities. CRD includes different aspects: being open about mistakes, critical opinion sharing, asking for and giving feedback, experimentation, challenging groupthink and research utilisation. In this article we explore whether CRD aspects change over time, through a study of two dialogues each from six different communities of veterinary health professionals. Change was studied from the perspective of observations, through analysing transcripts of dialogues, and from the perspective of community members' perceptions, through an evaluative discussion with members. The results showed that some communities became more open about mistakes, a finding that is related to an increase in trust. Other observed aspects of CRD seemed to be fairly stable over time. Community members perceived research utilisation and asking for and giving feedback to have been increased. From an analysis of perceptions of the community members it emerged that limited interaction could be associated with the epistemological conceptions of community members.

    Nursing students' clinical experiences are important with respect to their impact on attitudes towards care for older people and preferences for future workplaces. The purpose of this paper is to explore how professional dialogue has an impact on nursing students' clinical learning and professional development in nursing homes. A qualitative design based on field work, field notes and qualitative research interviews was employed with 12 third year nursing students undergoing clinical practise in three nursing homes in Norway. The nursing students who participated in this study displayed positive attitudes towards older people. However, their experiences and perceptions of the learning environment in the nursing homes, varied. The nursing students expressed that a positive learning environment included participation in nursing care and professional dialogue to support their learning process and outcomes. Their primary wish was to develop their knowledge about care for older people through participation and dialogue as critical and reflective processes in a community of practise.

  7. Biomedical engineering and society: policy and ethics.

    2007-01-01

    Biomedical engineering impacts health care and contributes to fundamental knowledge in medicine and biology. Policy, such as through regulation and research funding, has the potential to dramatically affect biomedical engineering research and commercialization. New developments, in turn, may affect society in new ways. The intersection of biomedical engineering and society and related policy issues must be discussed between scientists and engineers, policy-makers and the public. As a student, there are many ways to become engaged in the issues surrounding science and technology policy. At the University of Washington in Seattle, the Forum on Science Ethics and Policy (FOSEP, www.fosep.org) was started by graduate students and post-doctoral fellows interested in improving the dialogue between scientists, policymakers and the public and has received support from upper-level administration. This is just one example of how students can start thinking about science policy and ethics early in their careers.

  9. Guiding dialogue in the transformation of teacher-student relationships.

    PubMed

    Gaines, S; Baldwin, D

    1996-01-01

    The National League for Nursing at its 1989 biennial convention resolved that nursing curricula be revised to reflect enriched caring practices through egalitarian teacher-student and teacher-to-teacher relationships that reflect cooperation and a sense of community. The distribution of power relationships between student and teacher, teacher and teacher, and teacher and administrator must be reconceptualized and realized before any significant change in nursing education's curriculum can occur. Revising curricula to incorporate such a change in teacher-student relationships begins with dialogue with teachers that is authentic. Authentic dialogue will cause examination and reexamination of assumptions and ideologies about teacher-student relationships.

    Nonmarine sedimentary and volcaniclastic foreland-basin deposits in the Spring Mountains are cut by the Contact and Keystone thrusts. These synorogenic deposits, informally designated the Lavinia Wash sequence by Carr (1980), previously were assigned a Late Jurassic to Early Cretaceous(?) age. New 40Ar.39Ar laser-fusion and incremental-heating studies of a tuff bed in the Lavinia Wash sequence support a best estimate age of 99.0 ?? 0.4 Ma, indicating that the Lavinia Wash sequence is actually late Early Cretaceous in age and establishing a maximum age for final emplacement of the Contact and Keystone thrust plates consistent with the remainder of the Mesozoic foreland thrust belt. -from Authors

  18. Geology and Fluorspar Deposits of the Levias-Keystone and Dike-Eaton Areas, Crittenden County, Kentucky

    USGS Publications Warehouse

    Trace, Robert Denny

    1962-01-01

    The fault systems of the Levias-Keystone and Dike-Eaton areas, in the Kentucky-Illinois fiuorspar district, are a complex northeastward-trending sys- tem and a simple northwestward-trending system of steeply dipping normal faults, associated in part with a lamprophyre dike. Fluorspar mining started in the area about 1900 and, as of 1945, more than 200,000 tons of crude ore probably has been mined; most of the ore was from the Levias-Keystone area. A small quantity of zinc and lead ore also is present in the Dike-Eaton area. The deposits are localized along faults that displace fiat-lying or low-dipping limestones, sandstones, and shales of the Meramec and Chester series of Missis- sippian age. Movement along most of the faults was principally vertical, with displacement as much as 600 feet. Some horizontal movement occurred along at least one fault. Geologic mapping of the surface and data from underground workings have revealed 13 faults in an area of four-fifths of a square mile. Only a few of these faults are known to contain economically important deposits of fiuorspar. The most abundant vein minerals are calcite and fiuorite with subordinate quantities of sphalerite, galena, barite, and quartz. Some weathering products of sphalerite and galena are present also. The veins are dominantly calcite that contains fiuorite lenses but in places are mainly fiuorite having lesser quantities of calcite. Sphalerite- and galena-bearing deposits are present in the Dike-Eaton area. The ore bodies mainly are the result of fissure filling and replacement of calcite by fiuorite; in addition a small amount of limestone wallrock probably has been replaced. Residual concentrations of high-grade fluorspar in the overburden above faults have yielded some so-called gravel fiuorspar. The position of the veins within the faults may be related to one or more factors such as type of wallrock, change in dip of the fault, and amount of displacement.

    1997-01-01

    Between April 23, 1996, and June 21, 1996, the U.S. Environmental Protection Agency contracted Haliburton-NUS, Inc., to drill four clusters of three monitoring wells near the Keystone Sanitation Superfund Site. The purpose of the wells is to allow monitoring and sampling of shallow, intermediate, and deep waterbearing zones for the purpose of determining the horizontal and vertical distribution of any contaminated ground water migrating from the Keystone Site. Twelve monitoring wells, ranging in depth from 50 to 397.9 feet below land surface, were drilled in the vicinity of the Keystone Site. The U.S. Geological Survey conducted borehole-geophysical logging and determined, with geophysical logs and other available data, the ideal intervals to be screened in each well. Geophysical logs were run on four intermediate and four deep wells, and a caliper log only was run on shallow well CL-AD-173 (HN-1S). Interpretation of geophysical logs and existing data determined the placement of screens within each borehole.

  19. Dialogue procedures for the management of odour related community conflicts.

    PubMed

    Sucker, K

    2009-01-01

    In the German Guideline on Odour in Ambient Air (GOAA) statements about the degree of residential odour annoyance are based on the frequency of recognisable odours and hedonic tone. The use of olfactory standards to adequately estimate the annoyance impact is limited if, for example, worry about adverse health outcomes significantly influences the annoyance response of the population. This report introduces dialogue procedures as complementary measures to consider the complainants' subjective perceptions and worries adequately. At first, it is illustrated that odour exposure and number of odour complaints are not necessarily correlated. Then the "interest analysis" and the five steps of a dialogue procedure are presented. A dialogue procedure can be initiated in "quiet times" - where the focus is on trust building and on the development of adequate communication strategies to promote realistic risk reception - as well as in order to establish a successful conflict resolution process if the issue is complex and emotionally discussed. After that, two examples of handling odour complaints are shown. Finally, considerations applying dialogue procedures as a tool to advance odour annoyance mitigation are outlined.

    2017-01-01

    Bistatic forward-looking SAR (BFSAR) is a kind of bistatic synthetic aperture radar (SAR) system that can image forward-looking terrain in the flight direction of an aircraft. Until now, BFSAR imaging theories and methods for a stationary scene have been researched thoroughly. However, for moving-target imaging with BFSAR, the non-cooperative movement of the moving target induces some new issues: (I) large and unknown range cell migration (RCM) (including range walk and high-order RCM); (II) the spatial-variances of the Doppler parameters (including the Doppler centroid and high-order Doppler) are not only unknown, but also nonlinear for different point-scatterers. In this paper, we put forward an adaptive moving-target imaging method for BFSAR. First, the large and unknown range walk is corrected by applying keystone transform over the whole received echo, and then, the relationships among the unknown high-order RCM, the nonlinear spatial-variances of the Doppler parameters, and the speed of the mover, are established. After that, using an optimization nonlinear chirp scaling (NLCS) technique, not only can the unknown high-order RCM be accurately corrected, but also the nonlinear spatial-variances of the Doppler parameters can be balanced. At last, a high-order polynomial filter is applied to compress the whole azimuth data of the moving target. Numerical simulations verify the effectiveness of the proposed method. PMID:28125000

    • Premise of the study: Utah agave (Agave utahensis) and its putative subspecies, A. utahensis subsp. kaibabensis and A. utahensis subsp. utahensis, are keystone species of the Mojave Desert and Colorado Plateau in the southwestern United States. Here we developed microsatellite markers to study population structure and genetic diversity of the two subspecies of A. utahensis. • Methods and Results: We analyzed 22,386 454-pyrosequencing large contigs (>400 bp), derived from a genome reduction experiment consisting of A. utahensis accessions, for putative microsatellites. The use of unique multiplex barcodes for each of the Agave accessions allowed for the identification of putatively polymorphic microsatellites based solely on sequence alignment analysis. We report the characteristics of 11 polymorphic microsatellite loci based on a panel of 104 individuals from the two subspecies. The number of alleles per locus varied from three to eight, with an average of 5.5 alleles per locus. Observed and expected heterozygosity values ranged from 0.038 to 0.777 and 0.038 to 0.707, respectively. • Conclusions: The microsatellites identified here will be invaluable for future studies of population structure, polyploidy, and genetic diversity across the species.

    2015-01-01

    In a study of the traditional livelihoods of 12 Monpa and Brokpa villages in Arunachal Pradesh, India using social-ecological and participatory rural appraisal techniques, we found that the forest tree species paisang (Quercus griffithii, a species of oak) is vital to agroecosystem sustainability. Paisang trees are conserved both by individuals and through community governance, because their leaves play a crucial role in sustaining 11 traditional cropping systems of the Monpa peoples. An Indigenous institution, Chhopa, regulates access to paisang leaves, ensuring that the relationship between paisang and traditional field crop species within Monpa agroecosystems is sustainable. The Monpa farmers also exchange leaves and agricultural products for yak-based foods produced by the transhumant Brokpa, who are primarily yak herders. Yak herds also graze in paisang groves during winter. These practices have enabled the conservation of about 33 landraces, yak breeds, and a number of wild plants. Paisang thus emerged as a culturally important keystone species in the cultures and livelihoods of both Monpa and Brokpa. Ecological and conservation knowledge and ethics about paisang vary with gender, social systems, and altitudes. Labor shortages, however, have already caused some changes to the ways in which paisang leaves are used and yak grazing patterns are also changing in the face of changes in attitude among local landowners. Given new competing interests, incentives schemes are now needed to conserve the ecologically sustainable traditional livelihoods.

  10. Focusing vibrating targets in frequency-modulation continuous-wave-synthetic aperture radar with Doppler keystone transform

    2016-04-01

    Vibrating targets generally induce sinusoidal micro-Doppler modulation in high resolution synthetic aperture radar (SAR). They could cause defocused and ghost results by conventional imaging algorithms. This paper proposes a method on vibrating target imaging in frequency-modulation continuous-wave (FMCW) SAR systems. The continuous motion of sensor platform during pulse time is considered in the signal model. Based on Bessel series expansion of the signal in the azimuth direction, the influence of platform motion on the azimuth frequency is eliminated after dechirp and deskew. In addition, the range walk is compensated in the two-dimensional frequency domain by Doppler keystone transform. Next, using range cell migration correction, the azimuth quadratic phase compensation and the range curvature correction are made in range-Doppler domain for the focus of paired echoes. The residual video phase of paired echoes is eliminated, and vibration parameters are estimated to compensate in the sinusoidal modulation phase. Then the deghosted image of vibrating targets can be obtained. The proposed method is applicable to multiple targets with various vibrating states due to no need of a priori knowledge of targets. Finally, simulations are carried out to validate the effectiveness of the method in FMCW-SAR imaging of vibrating targets.

    STUDY OBJECTIVE—This paper is based on a qualitative study that aimed to identify factors that facilitate or impede evidence-based policy making at a local level in the UK National Health Service (NHS). It considers how models of research utilisation drawn from the social sciences map onto empirical evidence from this study.
DESIGN—A literature review and case studies of social research projects that were initiated by NHS health authority managers or GP fundholders in one region of the NHS. In depth interviews and document analysis were used.
SETTING—One NHS region in England.
PARTICIPANTS—Policy makers, GPs and researchers working on each of the social research projects selected as case studies.
MAIN RESULTS—The direct influence of research evidence on decision making was tempered by factors such as financial constraints, shifting timescales and decision makers' own experiential knowledge. Research was more likely to impact on policy in indirect ways, including shaping policy debate and mediating dialogue between service providers and users.
CONCLUSIONS—The study highlights the role of sustained dialogue between researchers and the users of research in improving the utilisation of research-based evidence in the policy process.

  12. The impact of social science research on health policy.

    PubMed

    Orosz, E

    1994-11-01

    The relationship between research and health policy is discussed from a policy process perspective, describing communication problems in the course of policy formulation, implementation and evaluation. Policy process is often expected by researchers to be rational, having logical sequence of steps and the objective evaluation of alternatives based on scientific knowledge. In fact, policies are often formulated without clear problem identification or based on wrong assumption. The timing of research and policy-making differs. Policy-makers need to respond quickly. Evaluations may be regarded by politicians as embarrassing if they point to a need for significant change. It is not satisfactory to consider only research and policy-making: their relationship is influenced by the media, different interest groups and by the general public. Health policy formulation is embedded in the general policy environment of particular societies. Some countries have a long tradition of consensus-building, while in others health reforms have been formulated and introduced in a centralized way. Traditional bio-medical thinking influences health policy-makers. The importance of social and political acceptability tends to be overlooked. The paper emphasizes that we are experiencing an era of scarcity of resources and growing tension concerning allocation decisions. Existing institutions provide insufficient incentives for policy-makers and researchers to promote public dialogue about such issues. The paper concludes that there is a need for new approaches to policy development and implementation, new structures in policy-making, changes in research financing and co-operation between disciplines and new structures for public participation in policy-making. Research should facilitate more open and democratic dialogue about policy options and the consequences of alternative choices.

  13. In dialogue with an avatar, language behavior is identical to dialogue with a human partner.

    2015-12-16

    The use of virtual reality (VR) as a methodological tool is becoming increasingly popular in behavioral research as its flexibility allows for a wide range of applications. This new method has not been as widely accepted in the field of psycholinguistics, however, possibly due to the assumption that language processing during human-computer interactions does not accurately reflect human-human interactions. Yet at the same time there is a growing need to study human-human language interactions in a tightly controlled context, which has not been possible using existing methods. VR, however, offers experimental control over parameters that cannot be (as finely) controlled in the real world. As such, in this study we aim to show that human-computer language interaction is comparable to human-human language interaction in virtual reality. In the current study we compare participants' language behavior in a syntactic priming task with human versus computer partners: we used a human partner, a human-like avatar with human-like facial expressions and verbal behavior, and a computer-like avatar which had this humanness removed. As predicted, our study shows comparable priming effects between the human and human-like avatar suggesting that participants attributed human-like agency to the human-like avatar. Indeed, when interacting with the computer-like avatar, the priming effect was significantly decreased. This suggests that when interacting with a human-like avatar, sentence processing is comparable to interacting with a human partner. Our study therefore shows that VR is a valid platform for conducting language research and studying dialogue interactions in an ecologically valid manner.

    This article describes and analyses a research based engagement by a university school of public health in Bangladesh aimed at raising public debate on sexuality and rights and making issues such as discrimination more visible to policy makers and other key stakeholders in a challenging context. The impetus for this work came from participation in an international research programme with a particular interest in bridging international and local understandings of sexual and reproductive rights. The research team worked to create a platform to broaden discussions on sexuality and rights by building on a number of research activities on rural and urban men's and women's sexual health concerns, and on changing concepts of sexuality and understandings of sexual rights among specific population groups in Dhaka city, including sexual minorities. Linked to this on-going process of improving the evidence base, there has been a series of learning and capacity building activities over the last four years consisting of training workshops, meetings, conferences and dialogues. These brought together different configurations of stakeholders - members of sexual minorities, academics, service providers, advocacy organisations, media and policy makers. This process contributed to developing more effective advocacy strategies through challenging representations of sexuality and rights in the public domain. Gradually, these efforts brought visibility to hidden or stigmatised sexuality and rights issues through interim outcomes that have created important steps towards changing attitudes and policies. These included creating safe spaces for sexual minorities to meet and strategise, development of learning materials for university students and engagement with legal rights groups on sexual rights. Through this process, it was found to be possible to create a public space and dialogue on sexuality and rights in a conservative and challenging environment like Bangladesh by bringing

    Process of distance control of mobile robots is investigated. Petri-Markov net for modeling of dialogue regime is worked out. It is shown, that sequence of operations of next subjects: a human operator, a dialogue computer and an onboard computer may be simulated with use the theory of semi-Markov processes. From the semi-Markov process of the general form Markov process was obtained, which includes only states of transaction generation. It is shown, that a real transaction flow is the result of «concurrency» in states of Markov process. Iteration procedure for evaluation of transaction flow parameters, which takes into account effect of «concurrency», is proposed.

  16. The rules of engagement: Power and interaction in dialogue events.

    This article reflects on the "dialogic turn," focusing on one analytical framework for understanding the wide range of processes that fall under the rubric of engagement. The notion of power-in-interaction is explored using a case study of informal dialogue, the Dana Centre, London. Using this framework I argue that we can understand public engagement events as hallmarked by conflict, but that this conflict emerges not in differing assessments of the value of different forms of knowledge but around the very form of a dialogue event; similarly, I suggest that the content of talk indicates that imposed hierarchies are continually re-negotiated. In concluding I reflect on some implications of using power in the analysis of engagement.

    The major problem faced by photons propagating through a physical channel is that of collective noise. This collective noise has the ability to reduce the number of quantum bits that are transmitted, thereby reduces the message fidelity. The traditional method of noise immunity is the use of entanglement purification, which consumes a lot of quantum resources in accomplishing the joint probability of noise immunity but does not guarantee accurate quantum dialog. In this paper, we investigate a new approach to quantum dialogue in which quantum information can be faithfully transmitted via a noisy channel. we constructs corresponding Decoherence Free Subspace(DFS), the quantum state after the change is in the maximally entangled state, so as to realize the fidelity of quantum dialogue model that can ensure the accuracy and noise resistance, and secret information exchange.

  18. The current dialogue between phenomenology and psychiatry: a problematic misunderstanding.

    A revival of the dialogue between phenomenology and psychiatry currently takes place in the best international journals of psychiatry. In this article, we analyse this revival and the role given to phenomenology in this context. Although this dialogue seems at first sight interesting, we show that it is problematic. It leads indeed to use phenomenology in a special way, transforming it into a discipline dealing with empirical facts, so that what is called "phenomenology" has finally nothing to do with phenomenology. This so-called phenomenology tallies however with what we have always called semiology. We try to explain the reasons why phenomenology is misused in that way. In our view, this transformation of phenomenology into an empirical and objectifying discipline is explained by the role attributed to phenomenology by contemporary authors, which is to solve the problems raised by the Diagnostic and Statistical Manual of Mental Disorders.

  19. Sharing stories: narrative and dialogue in responsive nursing evaluation.

    Responsive evaluation is an emerging vision and rationale for nursing evaluation. In this vision, evaluation is redefined as an engagement with all stakeholders about the value and meaning of their practice as a vehicle for learning, understanding, and improvement. In this article, the authors aim to illustrate the utility of a particular version of responsive evaluation, one that is connected with recent ideas about narrative and dialogue. They concentrate on methodological issues and use a case example to illustrate these issues. The case concerns a responsive evaluation of the quality of palliative care for cancer patients in a Dutch region. Methodological issues include the collection of stories through the use of conversational interviews. Stories can reveal the meaning and ambiguity of everyday situations. If evaluators listen to different stories and facilitate a dialogue about stories, this will enhance mutual understandings and promote respect, inclusiveness, and social equity.

  20. A Keystone Ant Species Provides Robust Biological Control of the Coffee Berry Borer Under Varying Pest Densities

    Species’ functional traits are an important part of the ecological complexity that determines the provisioning of ecosystem services. In biological pest control, predator response to pest density variation is a dynamic trait that impacts the provision of this service in agroecosystems. When pest populations fluctuate, farmers relying on biocontrol services need to know how natural enemies respond to these changes. Here we test the effect of variation in coffee berry borer (CBB) density on the biocontrol efficiency of a keystone ant species (Azteca sericeasur) in a coffee agroecosystem. We performed exclosure experiments to measure the infestation rate of CBB released on coffee branches in the presence and absence of ants at four different CBB density levels. We measured infestation rate as the number of CBB bored into fruits after 24 hours, quantified biocontrol efficiency (BCE) as the proportion of infesting CBB removed by ants, and estimated functional response from ant attack rates, measured as the difference in CBB infestation between branches. Infestation rates of CBB on branches with ants were significantly lower (71%-82%) than on those without ants across all density levels. Additionally, biocontrol efficiency was generally high and did not significantly vary across pest density treatments. Furthermore, ant attack rates increased linearly with increasing CBB density, suggesting a Type I functional response. These results demonstrate that ants can provide robust biological control of CBB, despite variation in pest density, and that the response of predators to pest density variation is an important factor in the provision of biocontrol services. Considering how natural enemies respond to changes in pest densities will allow for more accurate biocontrol predictions and better-informed management of this ecosystem service in agroecosystems.

    Background The knowledge about the capacity of organisms’ early life stages to adapt to elevated temperatures is very limited but crucial to understand how marine biota will respond to global warming. Here we provide a comprehensive and integrated view of biological responses to future warming during the early ontogeny of a keystone invertebrate, the squid Loligo vulgaris. Methodology/Principal Findings Recently-spawned egg masses were collected and reared until hatching at present day and projected near future (+2°C) temperatures, to investigate the ability of early stages to undergo thermal acclimation, namely phenotypic altering of morphological, behavioural, biochemical and physiological features. Our findings showed that under the projected near-future warming, the abiotic conditions inside the eggs promoted metabolic suppression, which was followed by premature hatching. Concomitantly, the less developed newborns showed greater incidence of malformations. After hatching, the metabolic burst associated with the transition from an encapsulated embryo to a planktonic stage increased linearly with temperature. However, the greater exposure to environmental stress by the hatchlings seemed to be compensated by physiological mechanisms that reduce the negative effects on fitness. Heat shock proteins (HSP70/HSC70) and antioxidant enzymes activities constituted an integrated stress response to ocean warming in hatchlings (but not in embryos). Conclusions/Significance The stressful abiotic conditions inside eggs are expected to be aggravated under the projected near-future ocean warming, with deleterious effects on embryo survival and growth. Greater feeding challenges and the lower thermal tolerance limits of the hatchlings are strictly connected to high metabolic demands associated with the planktonic life strategy. Yet, we found some evidence that, in the future, the early stages might support higher energy demands by adjusting some cellular functional properties

    Serological data accumulated during the past decade indicated that a variety of feral and domestic animals of the Delaware-Maryland-Virginia (DelMarVa) Peninsula were infected with Jamestown Canyon (JC) and/or Keystone (KEY) viruses (Bunyaviridae, California serogroup). Neutralizing (N) antibody to JC virus was most prevalent in white-tailed deer, sika deer, cottontail rabbits and horses. KEY virus N antibody was detected most frequently in gray squirrels and domestic goats. N antibody indicative of past infection by one or both viruses also was found in raccoons, horses and humans. JC and/or KEY virus N antibodies were not demonstrable in sera of several other species of small mammals and reptiles. Investigations were extended to evaluate the role of domestic goats as an amplifying host of JC and KEY viruses and to assess their potential as sentinels of virus transmission. Goats maintained in the Pocomoke Cypress Swamp during the summer season of 1978, acquired N antibodies to JC and KEY viruses. Following experimental inoculation with either JC or KEY virus, all goats developed N antibody despite the absence of a demonstrable viremia in most animals. Goats proved to be effective as sentinels for monitoring the transmission of JC and KEY viruses; however, the exceptionally low titers or absence of viremia following inoculation with these viruses would seem to preclude a potential virus-amplifying role for this species. Although findings implicated primarily gray squirrels and white-tailed deer as possible amplifying hosts of KEY and JC virus, respectively, further investigations will be required to clarify their role, particularly since both viruses may be maintained entirely by transovarial transmission.

    Multi-walled carbon nanotubes (MWCNTs) are one of the most important carbon Nanomaterials (NMs). The production and use of these carbon NMs is increasing rapidly and, therefore, the need to assess their presence in the environment and associated risks has become increasingly important. However, limited literature is available regarding the impacts induced in aquatic organisms by this pollutant, namely in invertebrate species. Diopatra neapolitana and Hediste diversicolor are keystone polychaete species inhabiting estuaries and shallow water bodies intertidal mudflats, frequently used to evaluate the impact of environmental disturbances in these systems. To our knowledge, no information is available on physiological and biochemical alterations on these two species due to MWCNTs exposure. Thus, the present study aimed to assess the toxic effects of different MWCNTs concentrations (0.01; 0.10 and 1.00mg/L) in both species physiological (regenerative capacity and respiration rate) and biochemical (energy reserves, metabolic activities, oxidative stress related biomarkers and neurotoxicity markers) performance, after 28 days of exposure. The results obtained revealed that exposure to MWCNTs induced negative effects on the regenerative capacity of D. neapolitana. Additionally, higher MWCNTs concentrations induced increased respiration rates in D. neapolitana. MWCNTs altered energy-related responses, with higher values of electron transport system activity, glycogen and protein concentrations in both polychaetes exposed to this contaminant. Furthermore, when exposed to MWCNTs both species showed oxidative stress with higher lipid peroxidation, lower ratio between reduced and oxidized glutathione, and higher activity of antioxidant (catalase and superoxide dismutase) and biotransformation (glutathione-S-transferases) enzymes in exposed organisms.

    Nutrient recycling by animals is a potentially important biogeochemical process in both terrestrial and aquatic ecosystems. Stoichiometric traits of individual species may result in some taxa playing disproportionately important roles in the recycling of nutrients relative to their biomass, acting as keystone nutrient recyclers. We examined factors controlling the relative contribution of 12 Neotropical fish species to nutrient recycling in four streams spanning a range of phosphorus (P) levels. In high-P conditions (135 microg/L soluble reactive phosphorus, SRP), most species fed on P-enriched diets and P excretion rates were high across species. In low-P conditions (3 microg/L SRP), aquatic food resources were depleted in P, and species with higher body P content showed low rates of P recycling. However, fishes that were subsidized by terrestrial inputs were decoupled from aquatic P availability and therefore excreted P at disproportionately high rates. One of these species, Astyanax aeneus (Characidae), represented 12% of the total population and 18% of the total biomass of the fish assemblage in our focal low-P study stream but had P excretion rates > 10-fold higher than other abundant fishes. As a result, we estimated that P excretion by A. aeneus accounted for 90% of the P recycled by this fish assemblage and also supplied approximately 90% of the stream P demand in this P-limited ecosystem. Nitrogen excretion rates showed little variation among species, and the contribution of a given species to ecosystem N recycling was largely dependent upon the total biomass of that species. Because of the high variability in P excretion rates among fish species, ecosystem-level P recycling could be particularly sensitive to changes in fish community structure in P-limited systems.

    Background Natural contamination and anthropogenic pollution of soils are likely to be major determinants of functioning and survival of keystone invertebrate taxa. Soil animals will have both evolutionary adaptation and genetically programmed responses to these toxic chemicals, but mechanistic understanding of such is sparse. The clitellate annelid Lumbricus rubellus is a model organism for soil health testing, but genetic data have been lacking. Results We generated a 17,000 sequence expressed sequence tag dataset, defining ~8,100 different putative genes, and built an 8,000-element transcriptome microarray for L. rubellus. Strikingly, less than half the putative genes (43%) were assigned annotations from the gene ontology (GO) system; this reflects the phylogenetic uniqueness of earthworms compared to the well-annotated model animals. The microarray was used to identify adult- and juvenile-specific transcript profiles in untreated animals and to determine dose-response transcription profiles following exposure to three xenobiotics from different chemical classes: inorganic (the metal cadmium), organic (the polycyclic aromatic hydrocarbon fluoranthene), and agrochemical (the herbicide atrazine). Analysis of these profiles revealed compound-specific fingerprints which identify the molecular responses of this annelid to each contaminant. The data and analyses are available in an integrated database, LumbriBASE. Conclusion L. rubellus has a complex response to contaminant exposure, but this can be efficiently analysed using molecular methods, revealing unique response profiles for different classes of effector. These profiles may assist in the development of novel monitoring or bioremediation protocols, as well as in understanding the ecosystem effects of exposure. PMID:18522720

    Recovery of the keystone herbivore Diadema antillarum after the 1983-1984 mass mortality event poses one of the greatest challenges to Caribbean coral reef conservation, yet our understanding of the problem remains severely limited. Whilst some recovery has been observed, this has been restricted to the shallows (≤5 m). We report a newly discovered, isolated population recovery on Banco Capiro, Honduras, representing the largest recorded post-mortality densities beyond the shallowest environments (0.74-2.27 individuals m-2 at depths ≥10 m) alongside an unusually high mean percentage scleractinian coral cover of 49-62 %, likely no coincidence. On the nearby island of Utila, we report D. antillarum densities of 0.003-0.012 individuals m-2 and scleractinian coral cover of 12 % at depths ≥10 m, "typical" for a contemporary Caribbean coral reef. The three order of magnitude disparity in population density between sites separated by <60 km presents a unique opportunity to investigate barriers preventing their region-wide recovery by simultaneously addressing a range of previously proposed hypotheses. Despite concerns over the impacts of asynchronous spawning in low-density populations, we find that recruitment is occurring on Utila. This suggests that, whilst Allee effects are likely to be a contributing factor, the major barriers suppressing recovery are instead impacting juvenile survival into adulthood. Similarly, variations in heterospecific echinoids, interspecific competitors, and nutrient availability fail to account for population differences. Instead, we highlight a lack of structural complexity on contemporary Caribbean reefs as the most likely explanation for the limited recovery through a lack of provision of juvenile predation refugia, representing a further consequence of the recent ubiquitous phase shifts throughout the region. Using these findings, we propose future management strategies to stimulate recovery and, consequently, reef health

    2014-12-01

    Peer Instruction (PI) is an evidence based pedagogy commonly used in undergraduate physics instruction. When asked questions designed to test conceptual understanding, it has been observed that the proportion of students choosing the correct answer increases following peer discussion; however, relatively little is known about what takes place during these discussions or how they are beneficial to the processes of learning physics [M. C. James and S. Willoughby, Am. J. Phys. 79, 123 (2011)]. In this paper a framework for analyzing PI discussions developed through the lens of the "resources model" [D. Hammer, Am. J. Phys. 64, 1316 (1996); D. Hammer et al., Information Age Publishing (2005)] is proposed. A central hypothesis for this framework is that the dialogue with peers plays a crucial role in activating appropriate cognitive resources, enabling the students to see the problem differently, and therefore to answer the questions correctly. This framework is used to gain greater insights into the PI discussions of first year undergraduate physics students at the University of Edinburgh, UK, which were recorded using Livescribe Smartpens. Analysis of the dialogues revealed three different types of resource activation corresponding to increasing cognitive grain size. These were activation of knowledge elements, activation of linkages between knowledge elements, and activation of control structures (epistemic games and epistemological frames). Three case studies are examined to illustrate the role that peer dialogue plays in the activation of these cognitive resources in a PI session. The implications for pedagogical practice are discussed.

    Words that are produced aloud--and especially self-produced ones--are remembered better than words that are not, a phenomenon labeled the production effect in the field of memory research. Two experiments were conducted to determine whether this effect can be generalized to dialogue, and how it might affect dialogue management. Triads (Exp. 1) or dyads (Exp. 2) of participants interacted to perform a collaborative task. Analyzing reference reuse during the interaction revealed that the participants were more likely to reuse the references that they had presented themselves, on the one hand, and those that had been accepted through verbatim repetition, on the other. Analyzing reference recall suggested that the greater accessibility of self-presented references was only transient. Moreover, among partner-presented references, those discussed while the participant had actively taken part in the conversation were more likely to be recalled than those discussed while the participant had been inactive. These results contribute to a better understanding of how individual memory processes might contribute to collaborative dialogue.

    Ecological network analysis (ENA) was used to study the effects of Pomatoschistus microps on energy transport through the food web, its impact on other compartments and its possible role as a keystone species in the trophic webs of an Arenicola tidal flat ecosystem and a sparse Zostera noltii bed ecosystem. Three ENA models were constructed: (a) model 1 contains data of the original food web from prior research in the investigated area by Baird et al. (2007), (b) an updated model 2 which included biomass and diet data of P. microps from recent sampling, and (c) model 3 simulating a food web without P. microps. A comparison of energy transport between the different models revealed that more energy is transported from lower trophic levels up the food chain, in the presence of P. microps (models 1 and 2) than in its absence (model 3). Calculations of the keystone index (KSi) revealed the high overall impact (measured as εi) of this fish species on food webs. In model 1, P. microps was assigned a low KSi in the Arenicola flat and in the sparse Z. noltii bed. Calculations in model 2 ranked P. microps first for keystoneness and εi in both communities, the Arenicola flat and the sparse Z. noltii bed. Taken together, our results give insight into the role of P. microps when considering a whole food web and reveal direct and indirect trophic interactions of this small-sized fish species. These results might illustrate the impact and importance of abundant, widespread species in food webs and facilitate further investigations.

This scoping review 1) identifies the range and nature of literature on the adoption of Open Dialogue in Scandinavia in places other than the original sites in Finland, and 2) summarises this literature. We included 33 publications. Most studies in this scoping review were published as "grey" literature and most grappled with how to implement Open Dialogue faithfully. In the Scandinavian research context, Open Dialogue was mainly described as a promising and favourable approach to mental health care.

  1. Evaluating the effects of trophic complexity on a keystone predator by disassembling a partial intraguild predation food web.

    1. Many taxa can be found in food webs that differ in trophic complexity, but it is unclear how trophic complexity affects the performance of particular taxa. In pond food webs, larvae of the salamander Ambystoma opacum occupy the intermediate predator trophic position in a partial intraguild predation (IGP) food web and can function as keystone predators. Larval A. opacum are also found in simpler food webs lacking either top predators or shared prey. 2. We conducted an experiment where a partial IGP food web was simplified, and we measured the growth and survival of larval A. opacum in each set of food webs. Partial IGP food webs that had either a low abundance or high abundance of total prey were also simplified by independently removing top predators and/or shared prey. 3. Removing top predators always increased A. opacum survival, but removal of shared prey had no effect on A. opacum survival, regardless of total prey abundance. 4. Surprisingly, food web simplification had no effect on the growth of A. opacum when present in food webs with a low abundance of prey but had important effects on A. opacum growth in food webs with a high abundance of prey. Simplifying a partial IGP food web with a high abundance of prey reduced A. opacum growth when either top predators or shared prey were removed from the food web and the loss of top predators and shared prey influenced A. opacum growth in a non-additive fashion. 5. The non-additive response in A. opacum growth appears to be the result of supplemental prey availability augmenting the beneficial effects of top predators. Top predators had a beneficial effect on A. opacum populations by reducing the abundance of A. opacum present and thereby reducing the intensity of intraspecific competition. 6. Our study indicates that the effects of food web simplification on the performance of A. opacum are complex and depend on both how a partial IGP food web is simplified and how abundant prey are in the food web.

    Emergent diseases may alter the structure and functioning of ecosystems by creating new biotic interactions and modifying existing ones, producing cascading processes along trophic webs. Recently, a new variant of the rabbit haemorrhagic disease virus (RHDV2 or RHDVb) arguably caused widespread declines in a keystone prey in Mediterranean ecosystems - the European rabbit (Oryctolagus cuniculus). We quantitatively assess the impact of RHDV2 on natural rabbit populations and in two endangered apex predator populations: the Iberian lynx (Lynx pardinus) and the Spanish Imperial eagle (Aquila adalberti). We found 60-70% declines in rabbit populations, followed by decreases of 65.7% in Iberian lynx and 45.5% in Spanish Imperial eagle fecundities. A revision of the web of trophic interactions among rabbits and their dependent predators suggests that RHDV2 acts as a keystone species, and may steer Mediterranean ecosystems to management-dependent alternative states, dominated by simplified mesopredator communities. This model system stresses the importance of diseases as functional players in the dynamics of trophic webs.

    The intelligent tutoring system (ITS) BRCA Gist is a Web-based tutor developed using the Shareable Knowledge Objects (SKO) platform that uses latent semantic analysis to engage women in natural-language dialogues to teach about breast cancer risk. BRCA Gist appears to be the first ITS designed to assist patients' health decision making. Two studies provide fine-grained analyses of the verbal interactions between BRCA Gist and women responding to five questions pertaining to breast cancer and genetic risk. We examined how "gist explanations" generated by participants during natural-language dialogues related to outcomes. Using reliable rubrics, scripts of the participants' verbal interactions with BRCA Gist were rated for content and for the appropriateness of the tutor's responses. Human researchers' scores for the content covered by the participants were strongly correlated with the coverage scores generated by BRCA Gist, indicating that BRCA Gist accurately assesses the extent to which people respond appropriately. In Study 1, participants' performance during the dialogues was consistently associated with learning outcomes about breast cancer risk. Study 2 was a field study with a more diverse population. Participants with an undergraduate degree or less education who were randomly assigned to BRCA Gist scored higher on tests of knowledge than those assigned to the National Cancer Institute website or than a control group. We replicated findings that the more expected content that participants included in their gist explanations, the better they performed on outcome measures. As fuzzy-trace theory suggests, encouraging people to develop and elaborate upon gist explanations appears to improve learning, comprehension, and decision making.

    2001-07-01

    Of all the human professions, psychiatry is most centrally concerned with the relationship of mind and brain. In many clinical interactions, psychiatrists need to consider both subjective mental experiences and objective aspects of brain function. This article attempts to summarize, in the form of a dialogue between a philosophically informed attending psychiatrist and three residents, the major philosophical positions on the mind-body problem. The positions reviewed include the following: substance dualism, property dualism, type identity, token identity, functionalism, eliminative materialism, and explanatory dualism. This essay seeks to provide a brief user-friendly introduction, from a psychiatric perspective, to current thinking about the mind-body problem.

    2001-03-01

    According to his 1644 speech, ``Areopagitica,'' the English poet John Milton visited Galileo in his villa in Arcetri in 1638 while Galileo was under house arrest for offending the Church authorities. This article explores the influences Galileo may have had on Milton's writing as a result of the presumed meeting between the two, and discusses some similarities between Galileo's Starry Messenger (1610) and Dialogue Concerning the Two Chief World Systems (1632) and Milton's Paradise Lost (1667). Teachers and students of physics, astronomy, and li!!terature can benefit from studying connections such as these between science and the arts.

    Recent advances in automatic speech recognition and related technologies allow computers to carry on conversations by telephone. We developed an intelligent dialogue system that interacts with hypertensive patients to collect data about their health status. Patients thus avoid the inconvenience of traveling for frequent face to face visits to monitor the clinical variables they can easily measure at home; the physician is facilitated in acquiring patient information and cardiovascular risk, which is evaluated from the data according to noted guidelines. Controlled trials to assess the clinical efficacy are under way.

  9. The policy and science of soil change - a Victorian perspective

    Fisher, Jane; Crawford, Michael C.

    2015-07-01

    Understanding and managing soil change is an important component of maintaining soil health and soil security which is important for the future of agricultural productivity in Victoria. Historically, soil policy in Victoria has been dealt with on the basis of a single issue. With the emergence of farming systems thinking, and the concept of soil health and soil security, a more holistic approach is now being taken. A seven-step policy framework has been developed that promotes dialogue between scientist and policy makers. The questions it asks (what is the problem and how can it be solved?) clarify the role of government investment, and developing partnerships between science and policy, enables early identification of potential policy problems and development of appropriate policy interventions to manage soil change and ultimately soil health, soil security and soil productivity.

    2010-01-01

    This paper stems from findings of a literature review and consultation with key informants to explore nursing best practices in public health with rural and isolated Aboriginal communities. It summarizes background information on population distribution, the impact of colonization on Aboriginal health and the potential benefits for nurses and communities in adopting a partnership approach, rather than risking cultural imposition while applying best practices and knowledge derived from the dominant culture. The authors provide an alternative working definition for best practices in the context of public health nursing with Aboriginal communities based on findings from the literature review and key informant consultations. Findings include three principles for the development and assessment of nursing best practices with isolated Aboriginal communities: use of indigenous frameworks, capacity building and cultural safety. The discussion highlights examples that demonstrate the feasibility and strengths of these three principles across a selection of isolated, rural and national settings. Implications include a call for nursing leaders, managers and policy makers to take up this challenge and support wider dialogue and action to enable nursing practice that supports the efforts of Aboriginal people to improve health and social conditions.

  11. Disability rights in dialogue with clinical genetics conference, May 31 to June 2, 1996

    SciTech Connect

    1996-12-31

    The issue of prenatal diagnosis and selective abortion has been hotly debated in the medical, genetic counselling, feminist, parents, disability rights and bio-ethics literature, each of the various positions critiquing each other. People from the disability rights community in particular have began to articulate a critical view of the practice of widespread prenatal diagnosis with intent to abort because the pregnancy might result in a child with a disability. Unfortunately, people from the various disciplines and perspectives, such as bioethics, disability rights, feminism and so forth, by and large, have tended only to write for themselves and their colleagues. Few people have crossed disciplines to try to talk to people with other views. The rapid advances of genome research have continued to produce new prenatal tests, raising many complex ethical questions regarding the applications of prenatal testing. But the widely disparate positions of the various factions has made it difficult to move toward formulation of public policy change necessary to encompass these new genetic technologies. Genetic counselling is in the front lines of the controversial social and ethical issues arising from prenatal diagnosis, in its interface between medical science and the consumer of services. The primary intent of the conference was to invite and facilitate productive dialogue between individuals and groups of people who have traditionally not interacted as a result of their disparate views on these issues and to learn from this process, emphasizing the involvement of people with disabilities and people who work in clinical genetics.

    1999-10-01

    This paper is a dialogue to explore the value and limitations of PA. Two skeptics acknowledge the utility of PA in organizing the scientific investigations that are necessary for confident siting and licensing of a repository; however, they maintain that the PA process, at least as it is currently implemented, is an essentially unscientific process with shortcomings that may provide results of limited use in evaluating actual effects on public health and safety. Conceptual uncertainties in a PA analysis can be so great that results can be confidently applied only over short time ranges, the antithesis of the purpose behind long-term, geologic disposal. Two proponents of PA agree that performance assessment is unscientific, but only in the sense that PA is an engineering analysis that uses existing scientific knowledge to support public policy decisions, rather than an investigation intended to increase fundamental knowledge of nature; PA has different goals and constraints than a typical scientific study. The proponents describe an ideal, six-step process for conducting generalized PA, here called probabilistic systems analysis (PSA); they note that virtually all scientific content of a PA is introduced during the model-building steps of a PSA; they content that a PA based on simple but scientifically acceptable mathematical models can provide useful and objective input to regulatory decision makers.

    Fitzgerald, Maureen H

    2004-01-01

    This paper, based on a broad body of relevant data, presents a dialogue that explores and integrates two important concepts: family and culture. An understanding of these concepts is important for enhancing occupational therapy practice, in particular a practice that claims to be client-centered and holistic. The dialogue focuses particularly on issues students involved in the Intercultural Interaction Project, The University of Sydney, Australia, in 2002 identified as important. These include: a lack of understanding of the concept of culture, the confounding of culture and ethnicity, considering culture as an issue only in families from "other" cultural backgrounds, assumptions about the nature of families and therapists' points of reference for making these assumptions, differences in client or family and therapist expectations, and how these expectations affect what happens in therapy and participants' level of satisfaction with the outcomes of the interactions involved. The information suggests that there is a need for a better understanding of how culture influences ideas about families and how to work with them.

  3. Cultural hegemony? Educators’ perspectives on facilitating cross-cultural dialogue

    2016-01-01

    Background We live in an age when education is being internationalized. This can confront students with ‘cultural hegemony’ that can result from the unequal distribution of power and privilege in global society. The name that is given to awareness of social inequality is ‘critical consciousness’. Cross-cultural dialogue provides an opportunity for learners to develop critical consciousness to counter cultural hegemony. The purpose of this research was to understand how learners engage with cross-cultural dialogue, so we can help them do so more effectively in the future. Method The setting for this research was an online discussion in an international health professions educator fellowship program. We introduced scenarios with cultural references to study the reaction of participants to cultural conversation cues. We used an inductive thematic analysis to explore power and hegemony issues. Results Participants reflected that personally they were more likely to take part in cross-cultural discussions if they recognized the context discussed or had prior exposure to educational settings with cultural diversity. They identified barriers as lack of skills in facilitating cross-cultural discussions and fear of offending others. They suggested deliberately introducing cultural issues throughout the curriculum. Conclusion Our results indicate that developing critical consciousness and cross-cultural competency will require instructional design to identify longitudinal opportunities to bring up cross-cultural issues, and training facilitators to foster cross-cultural discussions by asking clarifying questions and navigating crucial/sensitive conversations.

    After twenty years of transformation of Finnish mental health care, in the late 80s and early 90s of the last century, incidence of schizophrenia in Western Lapland dropped from 35/100,000 to 7/100,000. This phenomenon is linked with Yrjo O. Alanen et al. who investigated schizophrenia treatment outcomes and psychosocial rehabilitation of people with schizophrenia. Investigators focused on an individually tailored psychotherapeutic recovery plan during patient's hospitalization, including care for patients' families. Within the "Finnish National Schizophrenia Project" the principles of the Need-Adapted Treatment were created and 50% of Finland's country gained access to mobile crisis intervention teams. Further studies were continued within "Acute PsychosisIntegrated Treatment Project" (1992-1993) which locally, in Western Lapland, proceeded into "Open Dialogue in Acute Psychosis Project" (ODAP) (1994-1997). In this approach, all important decisions regarding the patient, including hospitalization or pharmacotherapy, are discussed not only with the entire therapeutic team, but also with the patient and his family members. Two - and five-year follow-ups demonstrated high treatment efficacy as well as important cost reduction in mental health care spending. First two"Open Dialogue Method" training courses for representatives of the medical, psychological, nursing and social care have been completed in Poland in October 2014. Studies evaluating the therapeutic effectiveness of the described approach are being planned.

    Background We live in an age when education is being internationalized. This can confront students with 'cultural hegemony' that can result from the unequal distribution of power and privilege in global society. The name that is given to awareness of social inequality is 'critical consciousness'. Cross-cultural dialogue provides an opportunity for learners to develop critical consciousness to counter cultural hegemony. The purpose of this research was to understand how learners engage with cross-cultural dialogue, so we can help them do so more effectively in the future. Method The setting for this research was an online discussion in an international health professions educator fellowship program. We introduced scenarios with cultural references to study the reaction of participants to cultural conversation cues. We used an inductive thematic analysis to explore power and hegemony issues. Results Participants reflected that personally they were more likely to take part in cross-cultural discussions if they recognized the context discussed or had prior exposure to educational settings with cultural diversity. They identified barriers as lack of skills in facilitating cross-cultural discussions and fear of offending others. They suggested deliberately introducing cultural issues throughout the curriculum. Conclusion Our results indicate that developing critical consciousness and cross-cultural competency will require instructional design to identify longitudinal opportunities to bring up cross-cultural issues, and training facilitators to foster cross-cultural discussions by asking clarifying questions and navigating crucial/sensitive conversations.

    Two fault-tolerant authenticated quantum dialogue protocols are proposed in this paper by employing logical Bell states as the quantum resource, which combat the collective-dephasing noise and the collective-rotation noise, respectively. The two proposed protocols each can accomplish the mutual identity authentication and the dialogue between two participants simultaneously and securely over one kind of collective noise channels. In each of two proposed protocols, the information transmitted through the classical channel is assumed to be eavesdroppable and modifiable. The key for choosing the measurement bases of sample logical qubits is pre-shared privately between two participants. The Bell state measurements rather than the four-qubit joint measurements are adopted for decoding. The two participants share the initial states of message logical Bell states with resort to the direct transmission of auxiliary logical Bell states so that the information leakage problem is avoided. The impersonation attack, the man-in-the-middle attack, the modification attack and the Trojan horse attacks from Eve all are detectable.

  7. Fault tolerant channel-encrypting quantum dialogue against collective noise

    In this paper, two fault tolerant channel-encrypting quantum dialogue (QD) protocols against collective noise are presented. One is against collective-dephasing noise, while the other is against collective-rotation noise. The decoherent-free states, each of which is composed of two physical qubits, act as traveling states combating collective noise. Einstein-Podolsky-Rosen pairs, which play the role of private quantum key, are securely shared between two participants over a collective-noise channel in advance. Through encryption and decryption with private quantum key, the initial state of each traveling two-photon logical qubit is privately shared between two participants. Due to quantum encryption sharing of the initial state of each traveling logical qubit, the issue of information leakage is overcome. The private quantum key can be repeatedly used after rotation as long as the rotation angle is properly chosen, making quantum resource economized. As a result, their information-theoretical efficiency is nearly up to 66.7%. The proposed QD protocols only need single-photon measurements rather than two-photon joint measurements for quantum measurements. Security analysis shows that an eavesdropper cannot obtain anything useful about secret messages during the dialogue process without being discovered. Furthermore, the proposed QD protocols can be implemented with current techniques in experiment.

    Open Dialogue is a model of mental health services that originated in Finland and has since, been taken up in trial teams worldwide. As this is a relatively unknown approach in the UK, it is important to tentatively explore perspectives of NHS staff and service-users. Sixty-one Open Dialogue conference attendees, both staff and service-users, were recruited for this study. A feedback questionnaire was administered to determine the extent to which they believed the key tenets of Open Dialogue were important to service user care, and the extent to which they existed within current NHS services. Analysis of data demonstrated a strong consensus on the importance of the key principles of Open Dialogue for mental health care and also moderate disagreement that these principles exist within current NHS service provision. The Open Dialogue principles may offer a useful framework in order to develop services in a clinically meaningful way.

    Highlights: • A review of public engagement in waste management decision-making is undertaken. • Enhanced public engagement is explored as a means to legitimise waste decisions. • Analytical–deliberative processes are explored as a tool for effective dialogue. • Considerations for integrating public values with technical analysis are outlined. • Insights into the design of appropriate public engagement processes are provided. - Abstract: The complexity of municipal waste management decision-making has increased in recent years, accompanied by growing scrutiny from stakeholders, including local communities. This complexity reflects a socio-technical framing of the risks and social impacts associated with selecting technologies and sites for waste treatment and disposal facilities. Consequently there is growing pressure on local authorities for stakeholders (including communities) to be given an early opportunity to shape local waste policy in order to encourage swift planning, development and acceptance of the technologies needed to meet statutory targets to divert waste from landfill. This paper presents findings from a research project that explored the use of analytical–deliberative processes as a legitimising tool for waste management decision-making. Adopting a mixed methods approach, the study revealed that communicating the practical benefits of more inclusive forms of engagement is proving difficult even though planning and policy delays are hindering development and implementation of waste management infrastructure. Adopting analytical–deliberative processes at a more strategic level will require local authorities and practitioners to demonstrate how expert-citizen deliberations may foster progress in resolving controversial issues, through change in individuals, communities and institutions. The findings suggest that a significant shift in culture will be necessary for local authorities to realise the potential of more inclusive decision

  15. National food fortification: a dialogue with reference to Asia: policy in evolution.

    Wahlqvist, Mark L

    2008-01-01

    Food fortification generally refers to the addition of micronutrients and other favourably bio-active food components to food-stuffs where there are recognised deficiencies in the target population. Each forticant has had or could have regulatory implications. It is understandable, although arguable, in the face of a limited food supply skewed, for the majority, in the direction of starchy staples of low essential nutrient density. Efforts, with plant breeding, to biofortify such foods are underway and likely to be safer, more sustainable and affordable than chemical additions. Unfortunately, with an increasingly refined and naturally tasteless food supply (salty, fatty, sugary and starchy), and where energy requirements are falling because of physical inactivity, micronutrient fortification is being used as a nutritional "fix-it' strategy. In Asia, there are several critical micro- nutrients. No one national fortification program can deal with all deficiencies is likely to be highly selective for the nutrients which have the greatest advocacy or are most recognisable. They also leave the other health promoting food properties like intactness, nutrient spectrum, and phytonutrient content un-addressed. A variety of food-stuffs, with different biological origins, is the preferred approach. Where an optimal food system is not in place, there may be justification for fortification if there is regular monitoring and surveillance of the food supply and health outcomes occurs; is a clear cost-risk-benefit advantage in such a strategy; are programs in place to improve the nutritional value of the basic food supply and is an "exit strategy' for the fortification program.

    Planning and scheduling in the face of uncertainty and change pushes the capabilities of both planning and dialogue technologies by requiring complex negotiation to arrive at a workable plan. Planning for use of semi-autonomous robots involves negotiation among multiple participants with competing scientific and engineering goals to co-construct a complex plan. In NASA applications this plan construction is done under severe time pressure so having a dialogue interface to the plan construction tools can aid rapid completion of the process. But, this will put significant demands on spoken dialogue technology, particularly in the areas of dialogue management and generation. The dialogue interface will need to be able to handle the complex dialogue strategies that occur in negotiation dialogues, including hypotheticals and revisions, and the generation component will require an ability to summarize complex plans. This demonstration will describe a work in progress towards building a spoken dialogue interface to the EUROPA planner for the purposes of planning and scheduling the activities of a semi-autonomous robot. A prototype interface has been built for planning the schedule of the Personal Satellite Assistant (PSA), a mobile robot designed for micro-gravity environments that is intended for use on the Space Shuttle and International Space Station. The spoken dialogue interface gives the user the capability to ask for a description of the plan, ask specific questions about the plan, and update or modify the plan. We anticipate that a spoken dialogue interface to the planner will provide a natural augmentation or alternative to the visualization interface, in situations in which the user needs very targeted information about the plan, in situations where natural language can express complex ideas more concisely than GUI actions, or in situations in which a graphical user interface is not appropriate.
