  1. Supergravity Actions with Integral Forms

    OpenAIRE

    Castellani, L.; Catenacci, R.; Grassi, P. A.

    2014-01-01

    Integral forms provide a natural and powerful tool for the construction of supergravity actions. They are generalizations of usual differential forms and are needed for a consistent theory of integration on supermanifolds. The group geometrical approach to supergravity and its variational principle are reformulated and clarified in this language. Central in our analysis is the Poincare' dual of a bosonic manifold embedded into a supermanifold. Finally, using integral forms we provide a proof ...

  2. Cue integration and the perception of action in intentional binding

    DEFF Research Database (Denmark)

    Wolpe, Noham; Haggard, Patrick; Siebner, Hartwig R;

    2013-01-01

    'Intentional binding' describes the perceived temporal attraction between a voluntary action and its sensory consequence. Binding has been used in health and disease as an indirect measure of awareness of action or agency, that is, the sense that one controls one's own actions. It has been proposed...... that binding results from cue integration, in which a voluntary action provides information about the timing of its consequences or vice versa. The perception of the timing of either event is then a weighted average, determined according to the reliability of each of these two cues. Here we tested...

    2013-01-01

    The human brain is facing a continuous stream of stimulus information delivered by multiple modalities and sensory channels and processed in distinct cortical regions. We discuss recent empirical and theoretical developments in addressing the question of how this distributed information is integrated into coherent representations (the so-called binding problem) with an emphasis on the principles and constraints underlying the integration of multiple (rather than redundant) features across different sensory modalities and across perception and action planning.

  6. Action and language integration: from humans to cognitive robots.

    Science.gov (United States)

    Borghi, Anna M; Cangelosi, Angelo

    2014-07-01

    The topic is characterized by a highly interdisciplinary approach to the issue of action and language integration. Such an approach, combining computational models and cognitive robotics experiments with neuroscience, psychology, philosophy, and linguistic approaches, can be a powerful means that can help researchers disentangle ambiguous issues, provide better and clearer definitions, and formulate clearer predictions on the links between action and language. In the introduction we briefly describe the papers and discuss the challenges they pose to future research. We identify four important phenomena the papers address and discuss in light of empirical and computational evidence: (a) the role played not only by sensorimotor and emotional information but also of natural language in conceptual representation; (b) the contextual dependency and high flexibility of the interaction between action, concepts, and language; (c) the involvement of the mirror neuron system in action and language processing; (d) the way in which the integration between action and language can be addressed by developmental robotics and Human-Robot Interaction.

  10. Integrated Assessment of Prevention and Restoration Actions to Combat Desertification

    Science.gov (United States)

    Bautista, S.; Orr, B. J.; Vallejo, R.

    2009-12-01

    Recent advances in desertification and land degradation research have provided valuable conceptual and analytical frameworks, degradation indicators, assessment tools and surveillance systems with respect to desertification drivers, processes, and impacts. These findings, together with stakeholders’ perceptions and local/regional knowledge, have helped to define and propose measures and strategies to combat land degradation. However, integrated and comprehensive assessment and evaluation of prevention and restoration strategies and techniques to combat desertification is still lacking, and knowledge on the feasibility and cost-effectiveness of the proposed strategies over a wide range of environmental and socio-economic conditions is very scarce. To address this challenge, we have launched a multinational project (PRACTICE - Prevention and Restoration Actions to Combat Desertification. An Integrated Assessment), funded by the European Commission, in order to link S & T advances and traditional knowledge on prevention and restoration practices to combat desertification with sound implementation, learning and adaptive management, knowledge sharing, and dissemination of best practices. The key activities for pursuing this goal are (1) to establish a platform and information system of long-term monitoring sites for assessing sustainable management and actions to combat desertification, (2) to define an integrated protocol for the assessment of these actions, and (3) to link project assessment and evaluation with training and education, adaptive management, and knowledge sharing and dissemination through a participatory approach involving scientists, managers, technicians, financial officers, and members of the public who are/were impacted by the desertification control projects. Monitoring sites are distributed in the Mediterranean Europe (Greece, Italy, Spain, and Portugal), Africa (Morocco, Namibia, South Africa), Middle East (Israel), China, and South and North

  11. Chinese immigration in Spain. Definitions and actions regarding social integration

    Directory of Open Access Journals (Sweden)

    Gladys Nieto

    2003-09-01

    Full Text Available Currently, the social integration of immigrants constitutes an imperative of the Spanish state as well as a demand of its civil society and of immigrant organisations. While local institutions declare that the Chinese population does not show a particular interest in integrating into this society, in the last few years the Chinese voluntary associations have developed a series of strategies that have brought them closer to the public administrations, producing, in turn, particular discursive elaborations on the social integration of their group. In this article, the author analyzes the way in which the institutions and their agents –coming both from the Chinese group and the receiving society— conceive of and/or apply in their practices certain actions linked to “social integration”. For this, she limits her observation to the Chinese voluntary associations, and exemplifies the conflicts and paradoxes of the processes of social integration when immigrant organisations findthemselves exposed to unequal requirements on the part of the country of origin and the destination country.

  12. Collaborative Action Research on Technology Integration for Science Learning

    Science.gov (United States)

    Wang, Chien-Hsing; Ke, Yi-Ting; Wu, Jin-Tong; Hsu, Wen-Hua

    2012-02-01

    This paper briefly reports the outcomes of an action research inquiry on the use of blogs, MS PowerPoint [PPT], and the Internet as learning tools with a science class of sixth graders for project-based learning. Multiple sources of data were essential to triangulate the key findings articulated in this paper. Corresponding to previous studies, the incorporation of technology and project-based learning could motivate students in self-directed exploration. The students were excited about the autonomy over what to learn and the use of PPT to express what they learned. Differing from previous studies, the findings pointed to the lack information literacy among students. The students lacked information evaluation skills, note-taking and information synthesis. All these findings imply the importance of teaching students about information literacy and visual literacy when introducing information technology into the classroom. The authors suggest that further research should focus on how to break the culture of "copy-and-paste" by teaching the skills of note-taking and synthesis through inquiry projects for science learning. Also, further research on teacher professional development should focus on using collaboration action research as a framework for re-designing graduate courses for science teachers in order to enhance classroom technology integration.

    2015-01-01

    Integration of cognition and emotion, discussed by Pessoa in The Cognitive-Emotional Brain (2013), is further illustrated by music. In music, I argue, this integration begins during mental control of the actions by which musical sounds are produced. Many emotional reactions to the music we hear are also strongly related to the actions by which musical sounds are produced. Studies involving music can further illuminate the integration of emotion and control of action throughout behavior. PMID:26787218

  18. On integrable codimension one Anosov actions of IR^k

    CERN Document Server

    Barbot, Thierry

    2010-01-01

    In this paper, we consider codimension one Anosov actions of IR^k, k ? 1, on closed connected orientable manifolds of dimension n+k with n? 3. We show that the fundamental group of the ambient manifold is solvable if and only if the weak foliation of codimension one is transversely affine. We also study the situation where one 1-parameter subgroup of IR^k admits a cross-section, and compare this to the case where the whole action is transverse to a fibration over a manifold of dimension n. As a byproduct, generalizing a Theorem by Ghys in the case k=1, we show that, under some assumptions about the smoothness of the sub-bundle E^ss ? E^uu, and in the case where the action preserves the volume, it is topologically equivalent to a suspension of a linear Anosov action of Z^k on T^n.

  4. Path integrals for actions that are not quadratic in their time derivatives

    OpenAIRE

    Cahill, Kevin

    2015-01-01

    The standard way to construct a path integral is to use a Legendre transformation to find the hamiltonian, to repeatedly insert complete sets of states into the time-evolution operator, and then to integrate over the momenta. This procedure is simple when the action is quadratic in its time derivatives, but in most other cases Legendre's transformation is intractable, and the hamiltonian is unknown. This paper shows how to construct path integrals when one can't find the hamiltonian because t...

  5. The quench action approach in finite integrable spin chains

    Science.gov (United States)

    Alba, Vincenzo; Calabrese, Pasquale

    2016-04-01

    We consider the problem of constructing the stationary state following a quantum quench, using the exact overlaps for finite size integrable models. We focus on the isotropic Heisenberg spin chain with initial state Néel or Majumdar–Ghosh (dimer), although the proposed approach is valid for an arbitrary integrable model. We consider only eigenstates which do not contain zero-momentum strings because the latter are affected by fictitious singularities that are very difficult to take into account. We show that the fraction of eigenstates that do not contain zero-momentum strings is vanishing in the thermodynamic limit. Consequently, restricting to this part of the Hilbert space leads to vanishing expectation values of local observables. However, it is possible to reconstruct the asymptotic values by properly reweighting the expectations in the considered subspace, at the price of introducing finite-size corrections. We also develop a Monte Carlo sampling of the Hilbert space which allows us to study larger systems. We accurately reconstruct the expectation values of the conserved charges and the root distributions in the stationary state, which turn out to match the exact thermodynamic results. The proposed method can be implemented even in cases in which an analytic thermodynamic solution is not obtainable.

  6. An integrated approach for vascular health: a call to action.

    Science.gov (United States)

    O'Neill, Blair J; Rana, Shadab N; Bowman, Vincent

    2015-01-01

    Vascular diseases such as stroke, myocardial infarction, most causes of heart failure, dementia, peripheral arterial disease, certain kidney, and many lung and eye conditions are a result of disorders in the blood vessels (large and small) throughout the entire human body. Vascular diseases are the leading cause of preventable death and disability in Canada. Most vascular diseases share common risk factors (high blood pressure, diabetes, dyslipidemia, and obesity), which can be influenced by modifiable health behaviours such as unhealthy diet, smoking, lack of physical activity, and stress. Ninety percent of Canadians face an increased risk, which could be modified by managing these health behaviours and risk factors. Canada's aging population, combined with alarming trends in obesity, physical inactivity, high blood pressure, and diabetes are expected to further increase the social and economic effect of vascular diseases in the coming decades, unless there are major changes in health policy. Even more concerning is the increase in vascular risk factors among Canada's youth, and ethnically diverse populations. Vascular diseases affect not only the patient, but also place burdens on their spouses, families, friends, and communities. Tremendous potential exists to reduce the effects of vascular diseases through healthy public policy, supporting Canadians to make healthy lifestyle changes, and coordinating efforts across the continuum of care in a patient-focused manner. Vascular health requires partnerships for action across many sectors including government, health care practitioners, academia, not-for-profit organizations, and the private sector. The health sector alone cannot solve this problem. PMID:25547559

  7. Path-integral action of a particle in the noncommutative phase-space

    CERN Document Server

    Gangopadhyay, Sunandan

    2016-01-01

    In this paper we construct a path integral formulation of quantum mechanics on noncommutative phase-space. We first map the system to an equivalent system on the noncommutative plane. Then by applying the formalism of representing a quantum system in the space of Hilbert-Schmidt operators acting on noncommutative configuration space, the path integral action of a particle is derived. It is observed that the action has a similar form to that of a particle in a magnetic field in the noncommutative plane. From this action the energy spectrum is obtained for the free particle and the harmonic oscillator potential. We also show that the nonlocal nature (in time) of the action yields a second class constrained system from which the noncommutative Heisenberg algebra can be recovered.

  8. Neurocognitive mechanisms of perception-action coordination: a review and theoretical integration.

    Science.gov (United States)

    Ridderinkhof, K Richard

    2014-10-01

    The present analysis aims at a theoretical integration of, and a systems-neuroscience perspective on, a variety of historical and contemporary views on perception-action coordination (PAC). We set out to determine the common principles or lawful linkages between sensory and motor systems that explain how perception is action-oriented and how action is perceptually guided. To this end, we analyze the key ingredients to such an integrated framework, examine the architecture of dual-system conjectures of PAC, and endeavor in an historical analysis of the key characteristics, mechanisms, and phenomena of PACs. This analysis will reveal that dual-systems views are in need of fundamental re-thinking, and its elements will be amalgamated with current views on action-oriented predictive processing into a novel integrative theoretical framework (IMPPACT: Impetus, Motivation, and Prediction in Perception-Action Coordination theory). From this framework and its neurocognitive architecture we derive a number of non-trivial predictions regarding conative, motive-driven PAC. We end by presenting a brief outlook on how IMPPACT might present novel insights into certain pathologies and into action expertise.

  9. Hands typing what hands do: Action-semantic integration dynamics throughout written verb production.

    Science.gov (United States)

    García, Adolfo M; Ibáñez, Agustín

    2016-04-01

    Processing action verbs, in general, and manual action verbs, in particular, involves activations in gross and hand-specific motor networks, respectively. While this is well established for receptive language processes, no study has explored action-semantic integration during written production. Moreover, little is known about how such crosstalk unfolds from motor planning to execution. Here we address both issues through our novel "action semantics in typing" paradigm, which allows to time keystroke operations during word typing. Specifically, we created a primed-verb-copying task involving manual action verbs, non-manual action verbs, and non-action verbs. Motor planning processes were indexed by first-letter lag (the lapse between target onset and first keystroke), whereas execution dynamics were assessed considering whole-word lag (the lapse between first and last keystroke). Each phase was differently delayed by action verbs. When these were processed for over one second, interference was strong and magnified by effector compatibility during programming, but weak and effector-blind during execution. Instead, when they were processed for less than 900ms, interference was reduced by effector compatibility during programming and it faded during execution. Finally, typing was facilitated by prime-target congruency, irrespective of the verbs' motor content. Thus, action-verb semantics seems to extend beyond its embodied foundations, involving conceptual dynamics not tapped by classical reaction-time measures. These findings are compatible with non-radical models of language embodiment and with predictions of event coding theory. PMID:26803393

    Science.gov (United States)

    Parisi, German I; Weber, Cornelius; Wermter, Stefan

    2015-01-01

    The visual recognition of complex, articulated human movements is fundamental for a wide range of artificial systems oriented toward human-robot communication, action classification, and action-driven perception. These challenging tasks may generally involve the processing of a huge amount of visual information and learning-based mechanisms for generalizing a set of training actions and classifying new samples. To operate in natural environments, a crucial property is the efficient and robust recognition of actions, also under noisy conditions caused by, for instance, systematic sensor errors and temporarily occluded persons. Studies of the mammalian visual system and its outperforming ability to process biological motion information suggest separate neural pathways for the distinct processing of pose and motion features at multiple levels and the subsequent integration of these visual cues for action perception. We present a neurobiologically-motivated approach to achieve noise-tolerant action recognition in real time. Our model consists of self-organizing Growing When Required (GWR) networks that obtain progressively generalized representations of sensory inputs and learn inherent spatio-temporal dependencies. During the training, the GWR networks dynamically change their topological structure to better match the input space. We first extract pose and motion features from video sequences and then cluster actions in terms of prototypical pose-motion trajectories. Multi-cue trajectories from matching action frames are subsequently combined to provide action dynamics in the joint feature space. Reported experiments show that our approach outperforms previous results on a dataset of full-body actions captured with a depth sensor, and ranks among the best results for a public benchmark of domestic daily actions.

  17. Path integral action and exact renormalization group dualities for quantum systems in noncommutative plane

    CERN Document Server

    2014-01-01

    We employ the path integral approach developed in [29] to discuss the (generalized) harmonic oscillator in a noncommutative plane. The action for this system is derived in the coherent state basis with additional degrees of freedom. From this the action in the coherent state basis without any additional degrees of freedom is obtained. This gives the ground state spectrum of the system. We then employ the exact renormalization group approach to show that a duality can be constructed between this (noncommutative) system and a commutative system.

    It is widely accepted that action and perception in humans functionally interact on multiple levels. Moreover, areas originally suggested to be predominantly motor-related, as the cerebellum, are also involved in action observation. However, as yet, few studies provided unequivocal evidence that the cerebellum is involved in the action perception coupling (APC), specifically in the integration of motor and multisensory information for perception. We addressed this question studying patients with focal cerebellar lesions in a virtual-reality paradigm measuring the effect of action execution on action perception presenting self-generated movements as point lights. We measured the visual sensitivity to the point light stimuli based on signal detection theory. Compared with healthy controls cerebellar patients showed no beneficial influence of action execution on perception indicating deficits in APC. Applying lesion symptom mapping, we identified distinct areas in the dentate nucleus and the lateral cerebellum of both hemispheres that are causally involved in APC. Lesions of the right ventral dentate, the ipsilateral motor representations (lobules V/VI), and most interestingly the contralateral posterior cerebellum (lobule VII) impede the benefits of motor execution on perception. We conclude that the cerebellum establishes time-dependent multisensory representations on different levels, relevant for motor control as well as supporting action perception. Ipsilateral cerebellar motor representations are thought to support the somatosensory state estimate of ongoing movements, whereas the ventral dentate and the contralateral posterior cerebellum likely support sensorimotor integration in the cerebellar-parietal loops. Both the correct somatosensory as well as the multisensory state representations are vital for an intact APC.

    In this article, we describe an innovative capstone course for preservice K-8 teachers integrating action research and a unifying theme in science (AAAS in Science for all Americans. Oxford University Press, New York, 1989; NRC in National science education standards. National Academy Press, Washington, DC, 1996). The goals of the capstone course are to increase student knowledge of the unifying theme, improve written communication skills, and introduce students to educational research. We provide evidence that each of these goals is met. Student growth in theme knowledge is demonstrated through concept maps, questionnaires, and previously reported assessments. Improved writing ability is demonstrated using the spelling and grammar checking feature of Microsoft Word. The analysis of action research reports demonstrates that students are able to connect their action research project results to previous research.

    2002-01-01

    The Polyakov world-line path integral describing the propagation of gluon field quanta is constructed by employing the background gauge fixing method and is subsequently applied to analytically compute the divergent terms of the one (gluonic) loop effective action to fourth order in perturbation theory. The merits of the proposed approach is that, to a given order, it reduces to performing two integrations, one over a set of Grassmann and one over a set of Feynman-type parameters through which one manages to accomodate all Feynman diagrams entering the computation at once.

    Levine, David N

    2007-02-15

    The Integrative Action of the Nervous System by the British physiologist Charles Sherrington was published 100 years ago. Its goal was to explain how the nervous system welds a collection of disparate body parts and organs into a unified individual. Sherrington postulated that the reflex is the simplest unit of nervous integration. He introduced the concept of the synapse as the site where elementary reflexes interact to enable more complex and unified behavior and argued that a synaptic nervous system facilitated the evolution of the cerebrum and cerebellum. The concept of the synapse as a physiological entity provided a theoretical schema into which the richly varied phenomenology of nineteenth century reflex physiology could be assimilated. Sherrington's book also provided the conceptual framework for a century of research into the mechanisms of synaptic transmission and the neuronal discharges associated with perception and action.

    Full Text Available This article was motivated by the conference entitled ‘Perception & Action – An Interdisciplinary Approach to Cognitive Systems Theory’, which took place September 14-16, 2010 at the Santa Fe Institute, NM, U.S.A. The goal of the conference was to bring together an interdisciplinary group of neuroscientists, roboticists and theorists to discuss the extent and implications of action-perception integration in the brain. The motivation for the conference was the realization that it is a widespread approach in biological, theoretical and computational neuroscience to investigate sensory and motor function of the brain in isolation from one another, while at the same time, it is generally appreciated that sensory and motor processing cannot be fully separated. Our article summarizes the key findings of the conference, provides a hypothetical model that integrates the major themes and concepts presented at the conference, and concludes with a perspective on future challenges in the field.

    In this paper, a power shaping control with integral action is employed to control active and reactive powers of wind turbines connected to the grid. As it is well known, power shaping allows finding a Lyapunov function which ensures stability. In contrast to other passivity-based control theories, the power shaping controller design allows to use easily measurable variables, such as voltages and currents which simplify the physical interpretation and, therefore, the controller synthesis. The strategy proposed is evaluated in the context of severe operating conditions, such as abrupt changes in the wind speed and voltage drops.

    In the field of social neuroscience, major branches of research have been instrumental in describing independent components of typical and aberrant social information processing, but the field as a whole lacks a comprehensive model that integrates different branches. We review existing research related to the neural basis of three key neural systems underlying social information processing: social perception, action observation, and theory of mind. We propose an integrative model that unites these three processes and highlights the posterior superior temporal sulcus (pSTS), which plays a central role in all three systems. Furthermore, we integrate these neural systems with the dual system account of implicit and explicit social information processing. Large-scale meta-analyses based on Neurosynth confirmed that the pSTS is at the intersection of the three neural systems. Resting-state functional connectivity analysis with 1000 subjects confirmed that the pSTS is connected to all other regions in these systems. The findings presented in this review are specifically relevant for psychiatric research especially disorders characterized by social deficits such as autism spectrum disorder. PMID:25660957

The integrals of geodesic motions are expressed in terms of Killing vectors and Killing-Yano tensors of these spaces. We present the set of functionally independent integrals of motion for the homogeneous Sasaki-Einstein space $T^{1,1}$. We discuss the integrability of geodesics and construct explicitly the action-angle variables.

    Blood vessels normally maintain stereotyped lumen diameters and their stable structures are crucial for vascular function. However, very little is known about the molecular mechanisms controlling the maintenance of vessel diameters and the integrity of endothelial cells. We investigated this issue in zebrafish embryos by a chemical genetics approach. Small molecule libraries were screened using live Tg(kdrl:GRCFP)zn1 transgenic embryos in which endothelial cells are specifically labeled with GFP. By analyzing the effects of compounds on the morphology and function of embryonic blood vessels after lumen formation, PP1, a putative Src kinase inhibitor, was identified as capable of specifically reducing vascular lumen size by interrupting endothelial-cell integrity. The inhibitory effect is not due to Src or general VEGF signaling inhibition because another Src inhibitor and Src morpholino as well as several VEGFR inhibitors failed to produce a similar phenotype. After profiling a panel of 22 representative mammalian kinases and surveying published data, we selected a few possible new candidates. Combinational analysis of these candidate kinase inhibitors established that PP1 induced endothelial collapse by inhibiting both the VEGFR2 and MAP kinase pathways. More importantly, combinatory use of two clinically approved drugs Dasatinib and Sunitinib produced the same phenotype. This is the first study to elucidate the pathways controlling maintenance of endothelial integrity using a chemical genetics approach, indicating that endothelial integrity is controlled by the combined action of the VEGFR2 and MAP kinase pathways. Our results also suggest the possible side effect of the combination of two anticancer drugs on the circulatory system.

    2007-04-01

    In 1906 Sir Charles Sherrington published The Integrative Action of the Nervous System, which was a collection of ten lectures delivered two years before at Yale University in the United States. In this monograph Sherrington summarized two decades of painstaking experimental observations and his incisive interpretation of them. It settled the then-current debate between the "Reticular Theory" versus "Neuron Doctrine" ideas about the fundamental nature of the nervous system in mammals in favor of the latter, and it changed forever the way in which subsequent generations have viewed the organization of the central nervous system. Sherrington's magnum opus contains basic concepts and even terminology that are now second nature to every student of the subject. This brief article reviews the historical context in which the book was written, summarizes its content, and considers its impact on Neurology and Neuroscience.

  15. Integral group actions on symmetric spaces and discrete duality symmetries of supergravity theories

    International Nuclear Information System (INIS)

    For G = G(ℝ), a split, simply connected, semisimple Lie group of rank n and K the maximal compact subgroup of G, we give a method for computing Iwasawa coordinates of K∖G using the Chevalley generators and the Steinberg presentation. When K∖G is a scalar coset for a supergravity theory in dimensions ≥3, we determine the action of the integral form G(ℤ) on K∖G. We give explicit results for the action of the discrete U-duality groups SL2(ℤ) and E7(ℤ) on the scalar cosets SO(2)∖SL2(ℝ) and [SU(8)/( ± Id)]∖E7(+7)(ℝ) for type IIB supergravity in ten dimensions and 11-dimensional supergravity reduced to D = 4 dimensions, respectively. For the former, we use this to determine the discrete U-duality transformations on the scalar sector in the Borel gauge and we describe the discrete symmetries of the dyonic charge lattice. We determine the spectrum-generating symmetry group for fundamental BPS solitons of type IIB supergravity in D = 10 dimensions at the classical level and we propose an analog of this symmetry at the quantum level. We indicate how our methods can be used to study the orbits of discrete U-duality groups in general

    Trust and cooperation constitute cornerstones of common-pool resource theory, showing that "prosocial" strategies among resource users can overcome collective action problems and lead to sustainable resource governance. Yet, antisocial behavior and especially the coexistence of prosocial and antisocial behaviors have received less attention. We broaden the analysis to include the effects of both "prosocial" and "antisocial" interactions. We do so in the context of marine protected areas (MPAs), the most prominent form of biodiversity conservation intervention worldwide. Our multimethod approach relied on lab-in-the-field economic experiments (n = 127) in two MPA and two non-MPA communities in Baja California, Mexico. In addition, we deployed a standardized fishers' survey (n = 544) to verify the external validity of our findings and expert informant interviews (n = 77) to develop potential explanatory mechanisms. In MPA sites, prosocial and antisocial behavior is significantly higher, and the presence of antisocial behavior does not seem to have a negative effect on prosocial behavior. We suggest that market integration, economic diversification, and strengthened group identity in MPAs are the main potential mechanisms for the simultaneity of prosocial and antisocial behavior we observed. This study constitutes a first step in better understanding the interaction between prosociality and antisociality as related to natural resources governance and conservation science, integrating literatures from social psychology, evolutionary anthropology, behavioral economics, and ecology.

    For women and children, especially those who are poor and disadvantaged, to benefit from primary health care, they need to access and use cost-effective interventions for maternal, newborn, and child health. The challenge facing weak health systems is how to deliver such packages. Experiences from countries such as Iran, Malaysia, Sri Lanka, and China, and from projects in countries like Tanzania and India, show that outcomes in maternal, newborn, and child health can be improved through integrated packages of cost-effective health-care interventions that are implemented incrementally in accordance with the capacity of health systems. Such packages should include community-based interventions that act in combination with social protection and intersectoral action in education, infrastructure, and poverty reduction. Interventions need to be planned and implemented at the district level, which requires strengthening of district planning and management skills. Furthermore, districts need to be supported by national strategies and policies, and, in the case of the least developed countries, also by international donors and other partners. If packages for maternal, newborn and child health care can be integrated within a gradually strengthened primary health-care system, continuity of care will be improved, including access to basic referral care before and during pregnancy, birth, the postpartum period, and throughout childhood.

  19. Integrating Methods for Developing Sustainability Indicators to Facilitate Learning and Action

    Full Text Available Bossel's (2001 systems-based approach for deriving comprehensive indicator sets provides one of the most holistic frameworks for developing sustainability indicators. It ensures that indicators cover all important aspects of system viability, performance, and sustainability, and recognizes that a system cannot be assessed in isolation from the systems upon which it depends and which in turn depend upon it. In this reply, we show how Bossel's approach is part of a wider convergence toward integrating participatory and reductionist approaches to measure progress toward sustainable development. However, we also show that further integration of these approaches may be able to improve the accuracy and reliability of indicators to better stimulate community learning and action. Only through active community involvement can indicators facilitate progress toward sustainable development goals. To engage communities effectively in the application of indicators, these communities must be actively involved in developing, and even in proposing, indicators. The accuracy, reliability, and sensitivity of the indicators derived from local communities can be ensured through an iterative process of empirical and community evaluation. Communities are unlikely to invest in measuring sustainability indicators unless monitoring provides immediate and clear benefits. However, in the context of goals, targets, and/or baselines, sustainability indicators can more effectively contribute to a process of development that matches local priorities and engages the interests of local people.

    It is desirable for robots to be able to linguistically understand human actions during human-robot interactions. Previous research has developed frameworks for encoding human full body motion into model parameters and for classifying motion into specific categories. For full understanding, the motion categories need to be connected to the natural language such that the robots can interpret human motions as linguistic expressions. This paper proposes a novel framework for integrating observation of human motion with that of natural language. This framework consists of two models; the first model statistically learns the relations between motions and their relevant words, and the second statistically learns sentence structures as word n-grams. Integration of these two models allows robots to generate sentences from human motions by searching for words relevant to the motion using the first model and then arranging these words in appropriate order using the second model. This allows making sentences that are the most likely to be generated from the motion. The proposed framework was tested on human full body motion measured by an optical motion capture system. In this, descriptive sentences were manually attached to the motions, and the validity of the system was demonstrated.

    Full Text Available One of the most important strategies to achieve the objectives of sustainable development is to promote a coherent legal system in the European Union. The trends and priorities are mapped and monitored under the Programme of Action on the environment. The environmental Action Programmes are documents underpinning EU environmental policy. The first of these programs was adopted by the European Council in 1972 and was followed by five others. These action programs are actually a combination of medium-term programs, coupled with a strategic approach and is characterized by a vertical and sectoral environmental problems. Since 1973, the European Community action program in the field of environment have become an increasingly important role. The European Community Treaty of 1986 is the legal basis of EU environmental policy. The Article 174 outlines environmental policy objectives and defines its purpose - ensuring a high level of environmental protection taking into account the diversity of situations in different regions of the European Union. The underlying objectives of EU environmental policy, under Article 174, are: • the preserve, protect and improve the environment; • the protection of human health; •the rational use of natural resources; •a promoting measures at international level to treat regional environmental issues. The Article 175 identifies the appropriate legislative procedures to this end and establishes the decisionmaking in environmental policy. The Article 176 allows Member States to adopt and stricter standards if it is deemed important and if it is justified. The "Sustainable development" is mentioned early in Art. 2 of the Treaty of Amsterdam Treaty which underlies the formation of the European Community. The Article 6 promotes sustainable development as a cross-cutting policy of the European Union, highlighting the need to integrate environmental protection requirements into the definition and implementation of EU

    Full Text Available In 2009, the conference of the parties of the United Nations Framework Convention on Climate Change recognized the need to engage communities and indigenous groups into the systems to monitor, report and verify the results of REDD+. Since then, many countries have started to prepare for REDD+ implementation. This article reviews early experiences under development in 11 projects financed by the Alliance Mexico REDD+ located in four Early Action Areas to identify the potential integration of Community Based Monitoring (CBM. The evaluation of the projects is made based on a multi-criteria analysis which considers the potential to produce information relevant for national monitoring systems and the prospects for sustained monitoring practices over time. Results indicate there are challenges to harmonizing monitoring practices and protocols between projects since activities proposed differ greatly from one project to another. Technical specifications for integrating local data into national systems are thus required. The results of these projects can help to identify best practices for planning and implementing REDD+. Findings indicate that in general, resources and capacities to gather, analyse and report information as part of CBM systems are in place in the projects, but usually these reside with non-local experts (i.e., NGOs and Academia; however, there are notable examples where these capacities reside in the communities. If national forest monitoring systems are geared to include information gathered through locally-driven processes REDD+ should promote activities that produce local benefits, but countries would need to build local capacities for managing and monitoring natural resources and would also need to create agreements for sharing and using local data. Otherwise, national systems may need to rely on monitoring practices external to communities, which depend on the continued availability of external financial resources.

    The mammalian vomeronasal organ encodes pheromone information about gender, reproductive status, genetic background and individual differences. It remains unknown how pheromone information interacts to trigger innate behaviors. In this study, we identify vomeronasal receptors responsible for detecting female pheromones. A sub-group of V1re clade members recognizes gender-identifying cues in female urine. Multiple members of the V1rj clade are cognate receptors for urinary estrus signals, as well as for sulfated estrogen (SE) compounds. In both cases, the same cue activates multiple homologous receptors, suggesting redundancy in encoding female pheromone cues. Neither gender-specific cues nor SEs alone are sufficient to promote courtship behavior in male mice, whereas robust courtship behavior can be induced when the two cues are applied together. Thus, integrated action of different female cues is required in pheromone-triggered mating behavior. These results suggest a gating mechanism in the vomeronasal circuit in promoting specific innate behavior.DOI: http://dx.doi.org/10.7554/eLife.03025.001. PMID:25073926

  8. An integrated approach for prospectively investigating a mode-of-action for rodent liver effects

    International Nuclear Information System (INIS)

    Registration of new plant protection products (e.g., herbicide, insecticide, or fungicide) requires comprehensive mammalian toxicity evaluation including carcinogenicity studies in two species. The outcome of the carcinogenicity testing has a significant bearing on the overall human health risk assessment of the substance and, consequently, approved uses for different crops across geographies. In order to understand the relevance of a specific tumor finding to human health, a systematic, transparent, and hypothesis-driven mode of action (MoA) investigation is, appropriately, an expectation by the regulatory agencies. Here, we describe a novel approach of prospectively generating the MoA data by implementing additional end points to the standard guideline toxicity studies with sulfoxaflor, a molecule in development. This proactive MoA approach results in a more robust integration of molecular with apical end points while minimizing animal use. Sulfoxaflor, a molecule targeting sap-feeding insects, induced liver effects (increased liver weight due to hepatocellular hypertrophy) in an initial palatability probe study for selecting doses for subsequent repeat-dose dietary studies. This finding triggered the inclusion of dose-response investigations of the potential key events for rodent liver carcinogenesis, concurrent with the hazard assessment studies. As predicted, sulfoxaflor induced liver tumors in rats and mice in the bioassays. The MoA data available by the time of the carcinogenicity finding supported the conclusion that the carcinogenic potential of sulfoxaflor was due to CAR/PXR nuclear receptor activation with subsequent hepatocellular proliferation. This MoA was not considered to be relevant to humans as sulfoxaflor is unlikely to induce hepatocellular proliferation in humans and therefore would not be a human liver carcinogen. - Highlights: • We prospectively generated MoA data into standard guideline toxicity studies. • A proactive MoA approach

    Full Text Available Impaired glucose metabolism and type 2 diabetes have been associated with cognitive decline, dementia, and with structural and functional brain features. However, it is unclear whether these associations differ in individuals that differ in familial longevity or age. Here, we investigated the association between parameters of glucose metabolism and microstructural brain integrity in offspring of long-lived families (offspring and controls; and age categories thereof. From the Leiden Longevity Study, 132 participants underwent oral glucose tolerance test to assess glycemia (fasted glucose and glucose area-under-the-curve (AUC, insulin resistance (fasted insulin, AUCinsulin, and homeostatic model assessment of insulin resistance (HOMA-IR, and pancreatic Beta cell secretory capacity (insulinogenic index. 3Tesla MRI and Magnetization Transfer (MT imaging MT-ratio peak-height was used to quantify differences in microstructural brain parenchymal tissue homogeneity that remain invisible on conventional MRI. Analyses were performed in offspring and age-matched controls, with and without stratification for age.In the full offspring group only, reduced peak-height in grey and white matter was inversely associated with AUCinsulin, fasted insulin, HOMA-IR and insulinogenic-index (all p65 years: in younger controls, significantly stronger inverse associations were observed between peak-height and fasted glucose, AUCglucose, fasted insulin, AUCinsulin and HOMA-IR in grey matter; and for AUCglucose, fasted insulin and HOMA-IR in white matter (all P-interaction<0.05. Although the strength of the associations tended to attenuate with age in the offspring group, the difference between age groups was not statistically significant. Thus, associations between impaired insulin action and reduced microstructural brain parenchymal tissue homogeneity were stronger in offspring compared to controls, and seemed to diminish with age.

    1999-01-01

    We analyzed occupational and mental health activities in an occupational health service and in a mental health service using the Method of Organizational Congruences (MOC). No technical actions in either services were dedicated to mental health at work although this is prescribed by the Italian law (833/76) and has a demand among the local shared users identified in this study. We propose integrated technical action for mental health in public health services to address the risk of stress, burnout and mobbing in the workplace. Attention is drawn to the need for further research on health services in the field of organization and mental well-being. PMID:10703191

    processes. For example, earthquake and tsunami exercises are conducted separately, without taking into consideration the compounding effects. Recognizing this deficiency, the UNESCO IOC Intergovernmental Coordination Group for the Tsunami and other Coastal Hazards Warning System for the Caribbean and Adjacent Regions (CARIBE EWS) which was established in 2005, decided to include the tsunami and earthquake impacts for the upcoming March 20, 2013 regional CARIBE WAVE/LANTEX tsunami exercise. In addition to the tsunami wave heights predicted by the National Weather Service Tsunami Warning Centers in Alaska and Hawaii, the USGS PAGER and SHAKE MAP results for the M8.5 scenario earthquake in the southern Caribbean were also integrated into the manual. Additionally, in recent catastrophic planning for Puerto Rico, FEMA did request the local researchers to determine both the earthquake and tsunami impacts for the same source. In the US, despite that the lead for earthquakes and tsunamis lies within two different agencies, USGS and NOAA/NWS, it has been very beneficial that the National Tsunami Hazard Mitigation Program partnership includes both agencies. By working together, the seismic and tsunami communities can achieve an even better understanding of the hazards, but also foster more actions on behalf of government officials and the populations at risk.

  18. An analysis of a large dataset on immigrant integration in Spain. The Statistical Mechanics perspective on Social Action

    Barra, Adriano; Contucci, Pierluigi; Sandell, Rickard; Vernia, Cecilia

    2014-02-01

    How does immigrant integration in a country change with immigration density? Guided by a statistical mechanics perspective we propose a novel approach to this problem. The analysis focuses on classical integration quantifiers such as the percentage of jobs (temporary and permanent) given to immigrants, mixed marriages, and newborns with parents of mixed origin. We find that the average values of different quantifiers may exhibit either linear or non-linear growth on immigrant density and we suggest that social action, a concept identified by Max Weber, causes the observed non-linearity. Using the statistical mechanics notion of interaction to quantitatively emulate social action, a unified mathematical model for integration is proposed and it is shown to explain both growth behaviors observed. The linear theory instead, ignoring the possibility of interaction effects would underestimate the quantifiers up to 30% when immigrant densities are low, and overestimate them as much when densities are high. The capacity to quantitatively isolate different types of integration mechanisms makes our framework a suitable tool in the quest for more efficient integration policies.

    Through analyzing the roll model of the integrated system of fin and anti-rolling tank, this paper uses binomial equation to simplify the module and check how the approximate parameters simulate the original function. Based on the simplified module, the influence of fin and anti-rolling tank on the coefficient items of the roll module is discussed, and the influencing factors between fin and anti-rolling tank are analysed. And through simulation, the influence of action between fin and anti-rolling tank on the static characteristics, and the integrated stabilization effect, are analyzed.

    2015-01-01

    Full Text Available Integral action has been a key tool for social development, regarding the achievements of the national government to recover legitimacy and governability. Since its beginning in 2002 and up to date, the consolidation process—represented in the National Policy of Territorial Consolidation and Reconstruction (NPTCR— has presented changes in its strategy, in line with current circumstances. This article is theoretically based on the concepts of legitimacy and governability and on the doctrine of integral action of the Armed Forces, complemented with the experience of officers who worked on this strategy or currently run it. Thus, this study offers recommendations to the national government for decision making in modifying the development of NPTCR, taking into account the current historical moment.

    Claudia Trotta

    2010-10-01

    Full Text Available In 2006-2007, the Italian National Committee to Combat Drought and Desertification promoted the execution of local action plans in some of the Italian regions. The aims of these plans were: to carry out specific actions at a local scale; to promote the integration of local policies; to involve the local communities in proposing strategies to be adopted; to harmonize the procedures among institutions in charge of adopting the policies. In this framework, ENEA carried out an evaluation of existing policies and programs to be considered in implementing a local action plan to combat desertification in the Apulia region. The application of the environmental and socio-economic measures of the regional Rural Development Plan 2007-2013 (PSR seemed to be an effective tool to positively influence human activities such as agriculture, breeding, and forestry, with the purpose of preserving or improving soil characteristics and overall environmental conditions, and eventually resulting in a reduction of desertification processes. Therefore, we proposed that these measures should be taken into account and effectively integrated into the Local Action Plan of the Apulia region. Additionally, we considered the four priority sectors identified by the National Action Plan (PAN to combat drought and desertification as the guiding principles to carry out our analysis. These sectors were: Soil Protection, Sustainable Water Management, Reduction of the Impact of Productive Activities, and Territorial Equilibrium. We also included Climate Change, in consideration of the alarming and urgent role it has assumed. The desertification-prone province of Foggia was selected as a pilot area in where to evaluate the influences that PSR measures can directly or indirectly have on desertification-related factors, and identify and implement specific actions. The Provincial Coordination Territorial Plan (PTCP of Foggia provided the basic land units for this analysis, the

  5. Neural alpha oscillations index the balance between self-other integration and segregation in real-time joint action.

    Novembre, Giacomo; Sammler, Daniela; Keller, Peter E

    2016-08-01

    Shared knowledge and interpersonal coordination are prerequisites for most forms of social behavior. Influential approaches to joint action have conceptualized these capacities in relation to the separate constructs of co-representation (knowledge) and self-other entrainment (coordination). Here we investigated how brain mechanisms involved in co-representation and entrainment interact to support joint action. To do so, we used a musical joint action paradigm to show that the neural mechanisms underlying co-representation and self-other entrainment are linked via a process - indexed by EEG alpha oscillations - regulating the balance between self-other integration and segregation in real time. Pairs of pianists performed short musical items while action familiarity and interpersonal (behavioral) synchronization accuracy were manipulated in a factorial design. Action familiarity referred to whether or not pianists had rehearsed the musical material performed by the other beforehand. Interpersonal synchronization was manipulated via congruent or incongruent tempo change instructions that biased performance timing towards the impending, new tempo. It was observed that, when pianists were familiar with each other's parts, millisecond variations in interpersonal synchronized behavior were associated with a modulation of alpha power over right centro-parietal scalp regions. Specifically, high behavioral entrainment was associated with self-other integration, as indexed by alpha suppression. Conversely, low behavioral entrainment encouraged reliance on internal knowledge and thus led to self-other segregation, indexed by alpha enhancement. These findings suggest that alpha oscillations index the processing of information about self and other depending on the compatibility of internal knowledge and external (environmental) events at finely resolved timescales.

  6. The Importance of Local Action Groups in the Romanian European Integration Process: an Empirical Study

    Directory of Open Access Journals (Sweden)

    Liviu-Cosmin MOSORA

    2012-01-01

    Full Text Available This article aims to examine the factors affecting the implementation of local action groups in Romania. A relatively new member state, Romania has the highest share of EU rural areas which generates and maintains a long series of regional disparities. Because of these disparities, the economy faces a number of issues that undermine the quality of human and social capital and reduce the growth potential: precarious social and economic infrastructure, reduced access to markets and thus to goods, a low level of both economic cohesion and living standards and a difficult access to education and training. From this perspective, the local action groups can contribute to the revival and development of urban areas, through the promotion of economic activities in adjacent rural areas. Therefore, an empirical analysis was conducted to study how economic and social disparities in the regional development of Romania influenced the implementation of local action groups.

    Language understanding is a long-standing problem in computer science. However, the human brain is capable of processing complex languages with seemingly no difficulties. This paper shows a model for language understanding using biologically plausible neural networks composed of associative memories. The model is able to deal with ambiguities on the single word and grammatical level. The language system is embedded into a robot in order to demonstrate the correct semantical understanding of the input sentences by letting the robot perform corresponding actions. For that purpose, a simple neural action planning system has been combined with neural networks for visual object recognition and visual attention control mechanisms. PMID:19203859

  11. Integrating transformative learning and action learning approaches to enhance ethical leadership for supervisors in the hotel business

    Directory of Open Access Journals (Sweden)

    Boonyuen Saranya

    2016-01-01

    Full Text Available Ethical leadership is now increasingly focused in leadership development. The main purpose of this study is to explore two methods of adult learning, action learning and transformative learning, and to use the methods to enhance ethical leadership. Building ethical leadership requires an approach that focuses on personal values, beliefs, or frames of references, which is transformative learning. Transformative learning requires a series of meetings to conduct critical discourse and to follow up the learning of learners. By organizing such action learning, human resource developers can optimize their time and effort more effectively. The authors have created a comprehensive model to integrate the two learning approaches in a general way that focuses not only on ethical leadership, but also on all kinds of behavioral transformation in the workplace in the hotel business or even other types of business.

  12. Do we have to take action today in front of climate change? The contribution of integrated models

    International Nuclear Information System (INIS)

    What shall we do in front of climatic change? Considering the potential seriousness of global risks, shall we start drastic policies of abatement of greenhouse gas emissions? Taking into account the cost of these policies and the uncertainties about the reality of risks, should we postpone the action? Do the efforts of emissions abatement make a good use of rare resources when the stake is only to gain few degrees of temperature and while we need today urgent developments to fight against poverty? One of the priorities of CIRED, a mixed research unit involved in the sustainable development issue, is to clarify the terms of the debate in order to avoid its transformation into a conflict which would paralyze any significant action. To do so, CIRED has elaborated 'integrated' models which allow to study the optimal answer to be adopted considering the size of uncertainties and the forcefulness of the controversies which characterize this subject.

    A path integral construction of superconformal field theories is presented based on gauged supersymmetric Wess-Zumino-Witten actions. The conformal charge of the model is identical to that of a GKO construction. Ghost modes appear in the formalism as a result of gauge fixing. As a consequence, the holomorphic stress-tensor T(z) and superconformal generator G(z) obtained in the construction have ghost contributions. Weak operator first-class constraints restrict the theory to physical states which satisfy the constraints. The superconformal algebra closes when evaluated between ghost-free physical states.

    Dengue is one of Brazil's most important public health challenges. Activities for its prevention and control have been based on the strategy of integrated management proposed in health policies, in which the central actors are the Endemic Disease Control Agent(ACE) and the Community Health Agent (ACS). This study analyzes consensus opinions produced by ACSs and ACEs on theactions for incorporating ACEs into the teams of the Family Health Strategy (ESF). It is a qualitative study from a large municipality in Brazil in which dengue is endemic, using a focus group of professionals that is subsequently analyzed using Collective Subject Discourse Analysis, supported by WebQDA. The results indicate consensus positions in relation to the following subjects: I) difficulty in the process of integration of ACSs and ACEs for control of dengue; II) inclusion of ACEs in the primary healthcare of the ESF; and III) absence of monitoring and assessment of the integrated actions. In conclusion, there are needs: to make participants more aware, seeking changes in behavior; to offer an environment of support to those involved with training courses about dengue; and to monitor the process of integration, and evaluate it periodically, creating indicators of quality and quantity.

    2008-12-01

    For 23 years, the US Agency for International Development's Famine Early Warning Systems Network (FEWS NET) has applied climate data analysis in support of timely food insecurity mitigation and adaptation in Africa. FEWS NET, therefore, provides a compelling example of a sector-specific climate service. We briefly review the phases, successes and shortcomings of the FEWS NET climate service, describe an improved long term climate service strategy, and present new research supporting an improved, integrated drought monitoring approach. Our new monitoring system emphasizes seamless links between historical precipitation archives, near real-time rainfall estimates, and 1-to-4 month statistical predictions. Assessment of forecast skill shows useful levels of accuracy for many regions during key periods of the growing season. Integrating these forecasts with near real time blended satellite-gauge precipitation observations facilitates early identification of mid-season agricultural drought. Integrated historical climate archives (1979-present) permit analysis of observed and forecast climate conditions in terms of historical probabilities and analogs. Tools specific to staple crops and pastoralist settings are then used to assess the likely impacts of hydrometeorological anomalies. These are geographically integrated with livelihoods information and interpreted in terms of current food security conditions and timelines to determine human consequences. A client-server web-mapping data portal will allow users to dynamically access the climate anomaly information, and visualize the results in conjunction with livelihood information.

  17. Integrating robotic action with biologic perception: A brain-machine symbiosis theory

    Science.gov (United States)

    Mahmoudi, Babak

    In patients with motor disability the natural cyclic flow of information between the brain and external environment is disrupted by their limb impairment. Brain-Machine Interfaces (BMIs) aim to provide new communication channels between the brain and environment by direct translation of brain's internal states into actions. For enabling the user in a wide range of daily life activities, the challenge is designing neural decoders that autonomously adapt to different tasks, environments, and to changes in the pattern of neural activity. In this dissertation, a novel decoding framework for BMIs is developed in which a computational agent autonomously learns how to translate neural states into action based on maximization of a measure of shared goal between user and the agent. Since the agent and brain share the same goal, a symbiotic relationship between them will evolve therefore this decoding paradigm is called a Brain-Machine Symbiosis (BMS) framework. A decoding agent was implemented within the BMS framework based on the Actor-Critic method of Reinforcement Learning. The rule of the Actor as a neural decoder was to find mapping between the neural representation of motor states in the primary motor cortex (MI) and robot actions in order to solve reaching tasks. The Actor learned the optimal control policy using an evaluative feedback that was estimated by the Critic directly from the user's neural activity of the Nucleus Accumbens (NAcc). Through a series of computational neuroscience studies in a cohort of rats it was demonstrated that NAcc could provide a useful evaluative feedback by predicting the increase or decrease in the probability of earning reward based on the environmental conditions. Using a closed-loop BMI simulator it was demonstrated the Actor-Critic decoding architecture was able to adapt to different tasks as well as changes in the pattern of neural activity. The custom design of a dual micro-wire array enabled simultaneous implantation of MI and

    p53's apoptotic program consists of transcription-dependent and transcription-independent pathways. In the latter, physical interactions between mitochondrial p53 and anti-and pro-apoptotic members of the Bcl2 family of mitochondrial permeability regulators are central. Using isogenic cell systems with defined deficiencies, we characterize in detail how mitochondrial p53 contributes to mitochondrial permeabilization, to what extent its action depends on other key Bcl2 family members and define its release activity. We show that mitochondrial p53 is highly efficient in inducing the release of soluble and insoluble apoptogenic factors by severely disrupting outer and inner mitochondrial membrane integrity. This action is associated with wild-type p53-induced oligomerization of Bax, Bak and VDAC and the formation of a stress-induced endogenous complex between p53 and cyclophilin D, normally located at the inner membrane. Tumor-derived p53 mutants are deficient in activating the Bax/Bak lipid pore. These actions are independent of Puma and Bax. Importantly, the latter distinguishes the mitochondrial from the cytosolic p53 death pathway.

  1. The Practical Integration of Action Research into Building Climate Literacy and Partnership with Key Influentials

    Estrada, M.

    2015-12-01

    Climate Education Partners (CEP) has been using an action research approach to build climate literacy and partnership with key influential (KI) leaders in the San Diego community. After identifying 6 key sectors that either (a) could reduce green house gas emissions and adapt to impacts, or (b) would be highly vulnerable to the impacts of climate change, we conducted 89 interviews with KIs from the San Diego region -- including elected officials, academics, laborers, and representatives from local businesses, non-profits, ethnic and cultural communities, faith-based groups, and special interest groups -- to assess their science knowledge and opinions about climate change and the impacts of climate change. Other questions asked were about KIs' personal efficacy, identity, values and engagement in pro-environmental behaviors related to climate change. The results of the interviews contributed to CEP's action research approach in two ways: 1) it provided critical data regarding which leaders wanted further engagement with CEP and what that engagement should entail (e.g., being a connector to other leaders, a spokesperson, or a participant in future educational activities), and 2) it provided key information about the extent to which "knowledge deficit" is related to use of climate change knowledge to inform engagement in mitigation and adaptive behaviors. Practically, the results were used to create a database that is being used to inform the contact and education of KIs. We were able to show, consistent with previous research and identity theory, that liberal leaders were more likely than conservatives to believe in, feel concern for, and be knowledgeable about climate change. However, engagement in mitigation behaviors- specifically making decisions that would reduce electricity, gas, or water use- were similar for both groups. These results are being used to create resources and direct climate education activities going forward.

    Service users have lacked substantial influence, access, and participation in social work education in Norway and Sweden. In this article the author presents comparative analyses of two participatory projects that have developed and implemented practices that integrate service users into academic social work education and empower service users. The Norwegian HUSK project and the Social Work as Mobilization and Entrepreneurship course, also known as the "Mobilization course," at Lund University in Sweden demonstrate collaboration between research, social work education, and service users. The conclusions focus on the importance of the empowering processes by including recognition and dialogue, co-learning in practice, and the use of neutral venues to ensure effective user participation. The inclusion of service users in social work education can improve both practice and education. PMID:25662088

    2009-12-19

    The execution of the OSBAT 24{sup o}il pipeline rehabilitation project, comprising the substitution of a 30 km section of the 37 years old pipeline has become a real benchmark in the history of this kind of job. The pipeline is inserted in one of the most sensitive environmental areas of the Sao Paulo State - the last Environmental Protection Area of the Mata Atlantica . The growth of human presence in its surroundings during the last three decades, has caused the right-of-way to be totally confined by luxury housing developments, streets, highways and resorts, as well as by the local communities and their activities, schools, and commerce. The pipeline runs through the Serra do Mar unstable mountain range slopes, with sequences of very steep hills and ravines followed by swamps and rivers. The success of such a challenging project - assembling the new line in a narrow ROW with all its restrictions, where the old line was still in operation, and complying with the tight work schedule required by PETROBRAS, was only possible due to a carefully managed combination of: accurate planning, best engineering methods and equipment and experienced workforce, deeply integrated in a massive effort towards safety, environmental care and social responsibility.

    2012-10-01

    There has been increasing awareness over recent years of the persisting burden of worldwide maternal, newborn, and child mortality. The majority of maternal deaths occur during labor, delivery, and the immediate postpartum period, with obstetric hemorrhage as the primary medical cause of death. Other causes of maternal mortality include hypertensive diseases, sepsis/infections, obstructed labor, and abortion-related complications. Recent estimates indicate that in 2009 an estimated 3.3 million babies died in the first month of life and that overall, 7.3 million children under 5 die each year. Recent data also suggest that sufficient evidence- and consensus-based interventions exist to address reproductive, maternal, newborn, and child health globally, and if implemented at scale, these have the potential to reduce morbidity and mortality. There is an urgent need to put elements in place to promote integrated interventions among healthcare professionals and their associations. What is needed is the political will and partnerships to implement evidence-based interventions at scale. PMID:22883919

    The Brazilian Ministry of Health proposed a research study involving municipal professional staff conducting both epidemiological and water quality surveillance to facilitate the integration of the data which they collected. It aimed to improve the intersectoral collaboration and health promotion activities in the municipalities, especially regarding drinking-water quality. We then conducted a study using the action-research approach. At its evaluation phase, a technique which we called 'the tree analogy' was applied in order to identify both possibilities and challenges related to the proposed interlinkage. Results showed that integrating the two data collection systems cannot be attained without prior institutional adjustments. It suggests therefore the necessity to unravel issues that go beyond the selection and the interrelation of indicators and compatibility of software, to include political, administrative and personal matters. The evaluation process led those involved to re-think their practice by sharing experiences encountered in everyday practice, and formulating constructive criticisms. All this inevitably unleashes a process of empowerment. From this perspective, we have certainly gathered some fruit from the Tree, but not necessarily the most visible.

  7. Complementary Actions

    Full Text Available Complementary colors are color pairs which, when combined in the right proportions, produce white or black. Complementary actions refer here to forms of social interaction wherein individuals adapt their joint actions according to a common aim. Notably, complementary actions are incongruent actions. But being incongruent is not sufficient to be complementary (i.e., to complete the action of another person. Successful complementary interactions are founded on the abilities: (i to simulate another person’s movements, (ii to predict another person’s future action/s, (iii to produce an appropriate incongruent response which differ, while interacting, with observed ones, and (iv to complete the social interaction by integrating the predicted effects of one’s own action with those of another person. This definition clearly alludes to the functional importance of complementary actions in the perception–action cycle and prompts us to scrutinize what is taking place behind the scenes. Preliminary data on this topic have been provided by recent cutting-edge studies utilizing different research methods. This mini-review aims to provide an up-to-date overview of the processes and the specific activations underlying complementary actions.

    2015-07-01

    Full Text Available Cities’ energy usage accounts for two thirds of global primary energy consumption. Energy efficiency in urban areas is, therefore, one of the most important topics to consider when dealing with urban sustainability. This paper evaluates the goals for increasing energy efficiency and use of renewable energy sources in the areas of transportation, buildings and consumers’ awareness, as stated in the Climate action plan, for the municipality of Eskilstuna, Sweden. The efforts of the municipality to successfully reach their energy efficiency goals, are described in this paper including future perspectives. The results show that although the municipality counts with the advantage of owning and working together with the local housing company and energy provider, in order to reach the established goals, additional strategies need to be considered. For an increased use of renewable energy sources, analysis of rooftops suitable for photovoltaic (PV installation should be carried out as well as the integration of goals for self-consumption. In the transport field, the city needs to prepare for large-scale electric vehicle (EV market penetration and to consider different bike or car sharing options. Finally, more specific awareness campaigns are needed to engage the citizens in reducing their energy consumption and living a more sustainable life.

    Among the genetic factors known to increase the risk of late onset Alzheimer's diseases (AD), the presence of the apolipoproteine e4 (APOE4) allele has been recognized as the one with the strongest effect. However, despite decades of research, the pathogenic role of APOE4 in Alzheimer's disease has not been clearly elucidated yet. In order to investigate the pathogenic action of APOE4, we applied a systems biology approach to the analysis of transcriptomic and genomic data of APOE44 vs. APOE33 allele carriers affected by Alzheimer's disease. Network analysis combined with a novel technique for biomarker computation allowed the identification of an alteration in aging-associated processes such as inflammation, oxidative stress and metabolic pathways, indicating that APOE4 possibly accelerates pathological processes physiologically induced by aging. Subsequent integration with genomic data indicates that the Notch pathway could be the nodal molecular mechanism altered in APOE44 allele carriers with Alzheimer's disease. Interestingly, PSEN1 and APP, genes whose mutation are known to be linked to early onset Alzheimer's disease, are closely linked to this pathway. In conclusion, APOE4 role on inflammation and oxidation through the Notch signaling pathway could be crucial in elucidating the risk factors of Alzheimer's disease. PMID:27585646

    Full Text Available Piezoelectric smart structures can be modeled using commercial finite element packages. Integration of control actions into the finite element model solutions (ICFES can be done in ANSYS by using parametric design language. Simulation results can be obtained easily in smart structures by this method. In this work, cantilever smart structures consisting of aluminum beams and lead-zirconate-titanate (PZT patches are considered. Two cases are studied numerically and experimentally in parallel. In the first case, a smart structure with a single PZT patch is used for the free vibration control under an initial tip displacement. In the second case, a smart structure with two PZT patches is used for the forced vibration control under harmonic excitation, where one of the PZT patches is used as vibration generating shaker while the other is used as vibration controlling actuator. For the two cases, modal analyses are done using chirp signals; Control OFF and Control ON responses in the time domain are obtained for various controller gains. A non-contact laser displacement sensor and strain gauges are utilized for the feedback signals. It is observed that all the simulation results agree with the experimental results.

    We consider a family of genus 2 hyperelliptic curves of even order and obtain explicitly the systems of 5 linear ordinary differential equations for periods of the corresponding Abelian integrals of first, second, and third kind, as functions of some parameters of the curves. The systems can be regarded as extensions of the well-studied Picard–Fuchs equations for periods of complete integrals of first and second kind on odd hyperelliptic curves. The periods we consider are linear combinations of the action variables of several integrable systems, in particular the generalized Neumann system with polynomial separable potentials. Thus the solutions of the extended Picard–Fuchs equations can be used to study various properties of the actions.

    AIM: To examine the effect of Eubacterium limosum (E.limosum) on colonic epithelial cell line in vitro, and to evaluate the effect of E.limosum on experimental colitis.METHODS: E.limosum was inoculated anaerobically and its metabolites were obtained. The growth stimulatory effect of the E.limosum metabolites on T84 cells was evaluated by SUDH activity, and the anti-inflammatory effect by IL-6 production. The change in mRNA of toll like receptor 4 (TLR4) was evaluated by real time PCR.Colitis was induced by feeding BALB/C mice with 2.0%dextran sodium sulfate. These mice received either 5%lyophilized E.limosum (n = 7) or control diet (n = 7).Seven days after colitis induction, clinical and histological scores, colon length, and cecal organic acid levels were determined.RESULTS: The E.limosum produced butyrate, acetate,propionate, and lactate at 0.25, 1.0, 0.025 and 0.07mmol/L, respectively in medium. At this concentration,each acid had no growth stimulating activity on T84cells; however, when these acids were mixed together at the above levels, it showed significantly high activity than control. Except for lactate, these acids significantly attenuated IL-6 production at just 0.1mmol/L. In addition, under TNF-α stimulation, butyrate attenuated the production of TLR4 mRNA. The treatment with E.limosum significantly attenuated clinical and histological scores of colitis with an increase of cecal butyrate levels, compared with the control group.CONCLUSION: E.limosum can ameliorate experimental colonic inflammation. In part, the metabolite of E.limosum, butyrate, increases mucosal integrity and shows anti-inflammatory action modulation of mucosal defense system via TLR4.

    The Hybrid Science Data System (HySDS) scalably powers the ingestion, metadata extraction, cataloging, high-volume data processing, and publication of the geodetic data products for the Advanced Rapid Imaging & Analysis for Monitoring Hazard (ARIA-MH) project at JPL. HySDS uses a heterogeneous set of worker nodes from private & public clouds as well as virtual & bare-metal machines to perform every aspect of the traditional science data system. For our science data users, the forefront of HySDS is the facet search interface, FacetView, which allows them to browse, filter, and access the published products. Users are able to explore the collection of product metadata information and apply multiple filters to constrain the result set down to their particular interests. It allows them to download these faceted products for further analysis and generation of derived products. However, we have also employed a novel approach to faceting where it is also used to apply constraints for custom monitoring of products, system resources, and triggers for automated data processing. The power of the facet search interface is well documented across various domains and its usefulness is rooted in the current state of existence of metadata. However, user needs usually extend beyond what is currently present in the data system. A user interested in synthetic aperture radar (SAR) data over Kilauea will download them from FacetView but would also want email notification of future incoming scenes. The user may even want that data pushed to a remote workstation for automated processing. Better still, these future products could trigger HySDS to run the user's analysis on its array of worker nodes, on behalf of the user, and ingest the resulting derived products. We will present our findings in integrating an ancillary, user-defined, system-driven processing system for HySDS that allows users to define faceted rules based on facet constraints and triggers actions when new SAR data

  1. Adaptive control of ionic polymer–metal composite in air and under water using a modified direct self-tuning regulator embedded with integral action

    International Nuclear Information System (INIS)

    Due to its large deformation response to a low voltage, ionic polymer–metal composite (IPMC) is a highly attractive actuator for many applications in air or under water. However, the dynamic characteristics of IPMC are nonlinear and vary with time, especially in water actuations. In this study, a modified direct self-tuning regulator (DSTR) with integral action was designed to control the tip-displacement of the IPMC, which is a non-minimum phase system to serve in air and underwater applications. The modified DSTR consisted of a pole-placement controller embedded with integral action, a reference model, and a self-tuning mechanism. The reference model specified the dynamic characteristic of the closed-loop IPMC system, and the controller parameters were automatically adjusted by the self-tuning mechanism to minimize the tracking error from the comparison between the response and the reference model output. The integral action may circumvent low-frequency distortions such as the back-relaxation phenomenon. Also, the DSTR may easily control the non-minimum phase system of the IPMC by tuning a delay factor in the reference model. The DSTR was implemented to control an IPMC (0.2 mm × 5 mm × 35 mm) actuated in air and under water, and the tracking performances were compared with a proportional-integral-derivative controller (PID). In contrast with the PID, the parameters of which were determined by the Ziegler–Nichols rule and produced large root-mean-squared tracking errors, the DSTR yielded good tracking performances for actuations both in air and under water from 0.01 to 1 Hz. Through control of the modified DSTR, IPMC may have a wide range of applications in the future

    Full Text Available The objective of this paper is to revisit some connections drawn from literature and others identified directly, between accountancy and the Theory of Communicative Action –henceforth TCA– as described by Jürgen Habermas, with a view to favouring an extension of the social role of accountancy towards social understanding and integration, and not just to globalisation and economic integration, as it is presented today. The paper, making use of TAC concepts, states that accountancy can be the product of social efforts aimed at creating a dialogue between companies and socio-economic actors. It compares in a critical way various concepts drawn from both volumes of the TAC with notions on the role of accountancy regarding development and neoliberal globalisation.

    Two far-reaching theoretical approaches, namely "Neuro-semeiotics" (NS) and "Free-energy Minimization" (FEM), have been recently proposed as frames within which to put forward heuristic hypotheses on integrative brain actions. In the present paper these two theoretical approaches are briefly discussed in the perspective of a recent model of brain architecture and information handling based on what we suggest calling Jacob's tinkering principle, whereby "to create is to recombine!". The NS and FEM theoretical approaches will be discussed from the perspective both of the Roamer-Type Volume Transmission (especially exosome-mediated) of intercellular communication and of the impact of receptor oligomers and Receptor-Receptor Interactions (RRIs) on signal recognition/decoding processes. In particular, the Bio-semeiotics concept of "adaptor" will be used to analyze RRIs as an important feature of NS. Furthermore, the concept of phenotypic plasticity of cells will be introduced in view of the demonstration of the possible transfer of receptors (i.e., adaptors) into a computational network via exosomes (see also Appendix). Thus, Jacob's tinkering principle will be proposed as a theoretical basis for some learning processes both at the network level (Turing-like type of machine) and at the molecular level as a consequence of both the plastic changes in the adaptors caused by the allosteric interactions in the receptor oligomers and the intercellular transfer of receptors. Finally, on the basis of NS and FEM theories, a unified perspective for integrative brain actions will be proposed. PMID:25175453

    Full Text Available This paper intends to go on with the study of problem solving in a compatible way with the theories of conceptual fields (TCC of Vergnaud (1990,1994,1998 and mental models of Johnson-Laird (1983,1990. Together with findings of another study (Escudero & Jaime 2007, some achievements and difficulties of freshmore engineering students when solving problems of the motion of rigid body in terms of the knowledge-in-action are analysed. The research methodology under a qualitative paradigm grouped data into categories which are not provided a priori by the theoretical framework. It can be said that the quality of the conceptual representation has been explicit in the quality of the proposed solution. Some meanings introduced by students in their problem solving activities can be characterized as operational invariants.

    The environmental sciences/studies movement, with more than 1000 programs at colleges and universities in the United States and Canada, is unified by a common interest-ameliorating environmental problems through empirical enquiry and analytic judgment. Unfortunately, environmental programs have struggled in their efforts to integrate knowledge across disciplines and educate students to become sound problem solvers and leaders. We examine the environmental program movement as a policy problem, looking at overall goals, mapping trends in relation to those goals, identifying the underlying factors contributing to trends, and projecting the future. We argue that despite its shared common interest, the environmental program movement is disparate and fragmented by goal ambiguity, positivistic disciplinary approaches, and poorly rationalized curricula, pedagogies, and educational philosophies. We discuss these challenges and the nature of the changes that are needed in order to overcome them. In a subsequent article (Part 2) we propose specific strategies for improvement. ?? 2011 Springer Science+Business Media, LLC.

  13. Reflection symmetry effects in the perturbation series of an action integral for the field line displacement in an ELMO Bumpy Torus

    International Nuclear Information System (INIS)

    Deviations from this ideal geometry and less-than-perfect alignment of the field coils in an ELMO Bumpy Torus generate perturbations to the ideal magnetic field configuration, resulting generally in failure of the field lines to close on themselves and thereby causing degradation in plasma confinement. The sensitivity of the field line displacement to certain types of errors in coil parameters is studied by means of a perturbation formalism developed for an action integral representing the longitudinal adiabatic invariant. Reflection symmetry properties satisfied by the magnetic field and the vector potential are derived, and it is demonstrated both analytically and numerically that the leading term of the field line displacement per period of 2π around the major axis is second order in the perturbation parameter if the coil planes remain invariant under the perturbation. Numerical analyses for the field line displacement also reveal some more useful properties for the first- and second-order terms in the perturbation series

    A strategy of integrating candidate metabolites with crucial biochemical factors was proposed in this study to discover relevant biological functions for interpreting the action mechanism of Traditional Chinese Medicines (TCM). This approach was applied to Xue-Sai-Tong injection (XST) to reveal the action mechanism based on the metabolic response in an ischemia/reperfusion (I/R) rat model by analyzing NMR profile. Partial least squares discriminate analysis (PLS-DA) was used to compare metabolic profiles of serum samples and revealed nine metabolites altered by I/R injury could be restored to normal status (sham-operated group) under the therapy of XST. The pathway enrichment analysis suggested the metabolic changes were mainly involved in pyruvate metabolism, glycolysis, and citrate cycle. The functional roles of the candidate metabolites were further identified by Pearson correlation analysis with the key biochemical factors in serum. The results indicated pyruvate, succinate, acetate and lysine showed significant associations with the oxidative stress factors. Elevated level of pyruvate was found as an essential metabolic response for the major effect of XST against I/R injury by enhancing glycolysis and overcoming the induced reactive oxygen species (ROS). This metabolomics approach provides a better understanding of the mechanisms of TCM and helps to develop a holistic view of TCM efficacy. PMID:26862062

  15. Robust and Accurate Closed-Loop Control of McKibben Artificial Muscle Contraction with a Linear Single Integral Action

    Directory of Open Access Journals (Sweden)

    Bertrand Tondu

    2014-06-01

    Full Text Available We analyze the possibility of taking advantage of artificial muscle’s own stiffness and damping, and substituting it for a classic proportional-integral-derivative controller (PID controller an I controller. The advantages are that there would only be one parameter to tune and no need for a dynamic model. A stability analysis is proposed from a simple phenomenological artificial muscle model. Step and sinus-wave tracking responses performed with pneumatic McKibben muscles are reported showing the practical efficiency of the method to combine accuracy and load robustness. In the particular case of the McKibben artificial muscle technology, we suggest that the dynamic performances in stability and load robustness would result from the textile nature of its braided sleeve and its internal friction which do not obey Coulomb’s third law, as verified by preliminary reported original friction experiments. Comparisons are reported between three kinds of braided sleeves made of rayon yarns, plastic, and thin metal wires, whose similar closed-loop dynamic performances are highlighted. It is also experimentally shown that a sleeve braided with thin metal wires can give high accuracy performance, in step as in tracking response. This would be due to a low static friction coefficient combined with a kinetic friction exponentially increasing with speed in accordance with hydrodynamic lubrication theory applied to textile physics.

    This project seeks to improve the ability of integrated assessment models (IA) to incorporate changes in technology, especially environmental technologies, cost and performance over time. In this report, we present results of research that examines past experience in controlling other major power plant emissions that might serve as a reasonable guide to future rates of technological progress in carbon capture and sequestration (CCS) systems. In particular, we focus on U.S. and worldwide experience with sulfur dioxide (SO{sub 2}) and nitrogen oxide (NO{sub x}) control technologies over the past 30 years, and derive empirical learning rates for these technologies. The patterns of technology innovation are captured by our analysis of patent activities and trends of cost reduction over time. Overall, we found learning rates of 11% for the capital costs of flue gas desulfurization (FGD) system for SO{sub 2} control, and 13% for selective catalytic reduction (SCR) systems for NO{sub x} control. We explore the key factors responsible for the observed trends, especially the development of regulatory policies for SO{sub 2} and NO{sub x} control, and their implications for environmental control technology innovation.

  17. Bridging the digital divide through the integration of computer and information technology in science education: An action research study

    Science.gov (United States)

    Brown, Gail Laverne

    The presence of a digital divide, computer and information technology integration effectiveness, and barriers to continued usage of computer and information technology were investigated. Thirty-four African American and Caucasian American students (17 males and 17 females) in grades 9--11 from 2 Georgia high school science classes were exposed to 30 hours of hands-on computer and information technology skills. The purpose of the exposure was to improve students' computer and information technology skills. Pre-study and post-study skills surveys, and structured interviews were used to compare race, gender, income, grade-level, and age differences with respect to computer usage. A paired t-test and McNemar test determined mean differences between student pre-study and post-study perceived skills levels. The results were consistent with findings of the National Telecommunications and Information Administration (2000) that indicated the presence of a digital divide and digital inclusion. Caucasian American participants were found to have more at-home computer and Internet access than African American participants, indicating that there is a digital divide by ethnicity. Caucasian American females were found to have more computer and Internet access which was an indication of digital inclusion. Sophomores had more at-home computer access and Internet access than other levels indicating digital inclusion. Students receiving regular meals had more computer and Internet access than students receiving free/reduced meals. Older students had more computer and Internet access than younger students. African American males had been using computer and information technology the longest which is an indication of inclusion. The paired t-test and McNemar test revealed significant perceived student increases in all skills levels. Interviews did not reveal any barriers to continued usage of the computer and information technology skills.

  18. Integrating Climate Change Scenarios and Co-developed Policy Scenarios to Inform Coastal Adaptation: Results from a Tillamook County, Oregon Knowledge to Action Network

    Local decision-makers often lack both the information and tools to reduce their community's overall vulnerability to current and future climate change impacts. Managers are restricted in their actions by the scale of the problem, inherent scientific uncertainty, limits of information exchange, and the global nature of available data, rendering place-based strategies difficult to generate. Several U.S. Pacific Northwest coastal communities are already experiencing chronic erosion and flooding, hazards only to be exacerbated by sea level rise and changing patterns of storminess associated with climate change. To address these issues, a knowledge to action network (KTAN) consisting of local Tillamook County stakeholders and Oregon State University researchers, was formed to project future flooding and erosion impacts and determine possible adaptation policies to reduce vulnerability. Via an iterative scenario planning process, the KTAN has developed four distinct adaptation policy scenarios, including 'Status Quo', 'Hold The Line', 'ReAlign', and 'Laissez-Faire'. These policy scenarios are being integrated with a range of climate change scenarios within the modeling framework Envision, a multi-agent GIS-based tool, which allows for the combination of physical processes data, probabilistic climate change information, coastal flood and erosion models, and stakeholder driven adaptation strategies into distinct plausible future scenarios. Because exact physical and social responses to climate change are impossible to ascertain, information about the differences between possible future scenarios can provide valuable information to decision-makers and the community at large. For example, the fewest projected coastal flood and erosion impacts to buildings occur under the 'ReAlign' policy scenario (i.e., adaptation strategies that move dwellings away from the coast) under both low and high climate change scenarios, especially in comparison to the 'Status Quo' or 'Hold The

    Several ion channels can be randomly and spontaneously in an open state, allowing the exchange of ion fluxes between extracellular and intracellular environments. We propose that the random changes in the state of ion channels could be also due to proteins exploring their energy landscapes. Indeed, proteins can modify their steric conformation under the effects of the physicochemical parameters of the environments with which they are in contact, namely, the extracellular, intramembrane and intracellular environments. In particular, it is proposed that the random walk of proteins in their energy landscape is towards attractors that can favor the open or close condition of the ion channels and/or intrinsic activity of G-protein-coupled receptors. The main aspect of the present proposal is that some relevant physicochemical parameters of the environments (e.g. molecular composition, temperature, electrical fields) with which some signaling-involved plasma membrane proteins are in contact alter their conformations. In turn, these changes can modify their information handling via a modulatory action on their random walk towards suitable attractors of their energy landscape. Thus, spontaneous and/or signal-triggered electrical activities of neurons occur that can have emergent properties capable of influencing the integrative actions of brain networks. Against this background, Cook's hypothesis on 'cell sentience' is developed by proposing that physicochemical parameters of the environments with which the plasma-membrane proteins of complex cellular networks are in contact fulfill a fundamental role in their spontaneous and/or signal-triggered activity. Furthermore, it is proposed that a specialized organelle, the primary cilium, which is present in most cells (also neurons and astrocytes), could be of peculiar importance to pick up chemical signals such as ions and transmitters and to detect physical signals such as pressure waves, thermal gradients, and local field

    Full Text Available Since 2013, the authors’ Japanese team in the Department of Science Education at Shizuoka University has held trials of STEM Education in informal fields as participatory action research (e.g., Science museum in Shizuoka, Lifelong Learning Center in Fujieda City, and STEM Summer camp for the preparation for implementing STEM education in public schools and for proposing science education reform in a Japanese context. Problems in preparing STEM lessons include numerous new instructional materials and programs and emerging specialized schools. In addition, while most of these initiatives address one or more of the STEM subjects separately, there are increasing calls for emphasizing connections between and among the subjects (Honey, Pearson and Schweingruber, 2014. Unfamiliar problems for Japanese teachers are, What is Engineering? What is Design? and How can they be implemented in lessons? While gathering STEM learning materials to implement in their STEM Summer Camp, the authors noticed a pattern with which to develop a STEM lesson and developed a template “T-SM-E” in reference to prior STEM studies. After the STEM Summer Camp, the authors introduced the model in the pre-service teacher preparation program. As a result, the authors received suggestions about how teachers can develop integrated STEM lessons, how undergraduate (UG teachers can implement it in their lessons, and how teachers can assess student learning in their STEM lessons. From standard based student assessments and reflections written by the UG teachers, the authors found that it was difficult for the UG teachers to include technology in their lessons, and their assessment also indicated that the students did not show performance proficiency in technology. The authors discuss this existing problem in the Japanese education system.

  2. Action semantics modulate action prediction.

    Springer, Anne; Prinz, Wolfgang

    2010-11-01

    Previous studies have demonstrated that action prediction involves an internal action simulation that runs time-locked to the real action. The present study replicates and extends these findings by indicating a real-time simulation process (Graf et al., 2007), which can be differentiated from a similarity-based evaluation of internal action representations. Moreover, results showed that action semantics modulate action prediction accuracy. The semantic effect was specified by the processing of action verbs and concrete nouns (Experiment 1) and, more specifically, by the dynamics described by action verbs (Experiment 2) and the speed described by the verbs (e.g., "to catch" vs. "to grasp" vs. "to stretch"; Experiment 3). These results propose a linkage between action simulation and action semantics as two yet unrelated domains, a view that coincides with a recent notion of a close link between motor processes and the understanding of action language.

  4. Recovery actions in PRA [probabilistic risk assessment] for the Risk Methods Integration and Evaluation Program (RMIEP): Volume 1, Development of the data-based method

    International Nuclear Information System (INIS)

    In a probabilistic risk assessment (PRA) for a nuclear power plant, the analyst identifies a set of potential core damage events consisting of equipment failures and human errors and their estimated probabilities of occurrence. If operator recovery from an event within some specified time is considered, then the probability of this recovery can be included in the PRA. This report provides PRA analysts with an improved methodology for including recovery actions in a PRA. A recovery action can be divided into two distinct phases: a Diagnosis Phase (realizing that there is a problem with a critical parameter and deciding upon the correct course of action) and an Action Phase (physically accomplishing the required action). In this methodology, simulator data are used to estimate recovery probabilities for the diagnosis phase. Different time-reliability curves showing the probability of failure of diagnosis as a function of time from the compelling cue for the event are presented. These curves are based on simulator exercises, and the actions are grouped based upon their operational similarities. This is an improvement over existing diagnosis models that rely greatly upon subjective judgment to obtain such estimates. The action phase is modeled using estimates from available sources. The methodology also includes a recommendation on where and when to apply the recovery action in the PRA process

    The necessity of mainstreaming climate adaptation strategies or policies into natural resource management plans has been recognized by the UNFCCC.The IPCC AR5 report suggests a growing demand for research to provide information for a deeper and more useful understanding of climate adaptation options,and indicates a lack of effective methods to meet this increasing demand of policymakers.In this respect,a participatory integrated assessment(PIA) approach is presented in this paper to provide an effective means to mainstream wetland climate change adaptation in rural sustainable development strategies,and thus to reduce climate vulnerability and to enhance rural community livelihood.The PIA approach includes a series of research activities required to assess climate impacts on wetland ecosystems,and to prioritize adaptation responses.A range of adaptation options that address key aspects of the wetland ecosystem resilience and concerns are evaluated against community based on sustainable development indicators.The PIA approach is able to identify desirable adaptation options which can then be implemented to improve wetland ecosystem health and to enhance regional sustainable development in a changing climate.For illustration purpose,the PIA was applied in a case study in Poyang Lake(PYL) region,a critical wetland and water ecosystem in central China with important international biodiversity linkages,and a locale for key policy experiments with ecosystem rehabilitation.The PIA was used to facilitate the integration of wetland climate change adaptation in rural sustainable development actions with multi-stakeholders participation.In particular,the case shows how the PIA can be designed and implemented to select effective and practical climate change adaptation options to enhance ecosystem services management and to reduce resource use conflicts and rural poverty.Worked in partnership with multi-stakeholders and assisted with a multi-criteria decision making tool

Taylor, Am. J. Phys. 71, 423-425 (2003)]. We report on our response to that call in the form of an investigation of the teaching and learning of the stationary action formulation of physics in a first-year university course. Our action physics instruction proceeded from the many-paths approach to quantum physics to ray optics, classical mechanics, and relativity. Despite the challenges presented by action physics, students reported it to be accessible, interesting, motivational, and valuable.

  11. Early changes of the integral cerebral systems of rats as a result of combined action of ethanol and γ-irradiation

    International Nuclear Information System (INIS)

    A study was made of Wistar male rats with the body mass of 250-270 g using neurohistological, electron microscopic and biochemical methods. The animals' heads were irradiated with γ-quanta at a dose of 50 Gy, the rate of 6.7 sGy/s. Two minutes before or right after irradiation 15 % ethanol solution (0.28 and 2.25 g/kg) was administered intraperitoneally. It was established that changes of interneuronal contacts in γ-irradiation of the head were similar in nature to those caused by ethanol (2.25 g/kg). The effects of combined action of the above factors depended on the succession of exposure and a dose of ethanol. Slightly more noticeable synaptic changes, probably associated with mitochondrion affection and hyperhydration, were noted in ethanol administration (2.25 g/kg) after irradiation of the head

    Although the association between habitual exercise and health benefits has been well documented, physical activity levels in the United States are lower than is necessary to reach the nation's health potential. Beliefs that people hold can be a motivating factor in engaging in exercise. A critical review of the literature was conducted to assess the efficacy of using the Theory of Reasoned Action and the Theory of Planned Behavior with respect to exercise. Evidence for the predictive utility of the theories was found. The Theory of Planned Behavior is a more promising framework for the study of exercise because it includes beliefs about control of factors that would facilitate or inhibit carrying out exercise. Strategies for use of the theories in planning exercise programs are provided and suggestions for future research discussed.

    Full Text Available Abstract Background In the Latin America and Caribbean region over 210 million people live below the poverty line. These impoverished and marginalized populations are heavily burdened with neglected communicable diseases. These diseases continue to enact a toll, not only on families and communities, but on the economically constrained countries themselves. Discussion As national public health priorities, neglected communicable diseases typically maintain a low profile and are often left out when public health agendas are formulated. While many of the neglected diseases do not directly cause high rates of mortality, they contribute to an enormous rate of morbidity and a drastic reduction in income for the most poverty-stricken families and communities. The persistence of this "vicious cycle" between poverty and poor health demonstrates the importance of linking the activities of the health sector with those of other sectors such as education, housing, water and sanitation, labor, public works, transportation, agriculture, industry, and economic development. Summary The purpose of this paper is three fold. First, it focuses on a need for integrated "pro-poor" approaches and policies to be developed in order to more adequately address the multi-faceted nature of neglected diseases. This represents a move away from traditional disease-centered approaches to a holistic approach that looks at the overarching causes and mechanisms that influence the health and well being of communities. The second objective of the paper outlines the need for a specific strategy for addressing these diseases and offers several programmatic entry points in the context of broad public health measures involving multiple sectors. Finally, the paper presents several current Pan American Health Organization and other institutional initiatives that already document the importance of integrated, inter-programmatic, and inter-sectoral approaches. They provide the framework for a

    Watershed morphometric analysis is important for controlling floods and planning restoration actions. The present study is focused on the identification of suitable sites for locating water harvesting structures using morphometric analysis and multi-criteria based decision support system. The Hathmati watershed of river Hathmati at Idar taluka, Sabarkantha district, Gujarat is experiencing excessive runoff and soil erosion due to high intensity rainfall. Earth observation dataset such as Digital Elevation Model and Geographic Information System are used in this study to determine the quantitative description of the basin geometry. Several morphometric parameters such as stream length, elongation ratio, bifurcation ratio, drainage density, stream frequency, texture ratio, form factor, circularity ratio, and compactness coefficient are taken into account for prioritization of Hathmati watershed. The overall analysis reveals that Hathmati comprises of 13 mini-watersheds out of which, the watershed number 2 is of utmost priority because it has the highest degradation possibilities. The final results are used to locate the sites suitable for water harvesting structures using geo-visualization technique. After all the analyses, the best possibilities of check dams in the mini-watersheds that can be used for soil and water conservation in the watershed are presented.

    Full Text Available The Library of Integrated Network-based Cellular Signatures (LINCS project is a large-scale coordinated effort to build a comprehensive systems biology reference resource. The goals of the program include the generation of a very large multidimensional data matrix and informatics and computational tools to integrate, analyze, and make the data readily accessible. LINCS data include genome-wide transcriptional signatures, biochemical protein binding profiles, cellular phenotypic response profiles and various other datasets for a wide range of cell model systems and molecular and genetic perturbations. Here we present a partial survey of this data facilitated by data standards and in particular a robust compound standardization workflow; we integrated several types of LINCS signatures and analyzed the results with a focus on mechanism of action and chemical compounds. We illustrate how kinase targets can be related to disease models and relevant drugs. We identified some fundamental trends that appear to link Kinome binding profiles and transcriptional signatures to chemical information and biochemical binding profiles to transcriptional responses independent of chemical similarity. To fill gaps in the datasets we developed and applied predictive models. The results can be interpreted at the systems level as demonstrated based on a large number of signaling pathways. We can identify clear global relationships, suggesting robustness of cellular responses to chemical perturbation. Overall, the results suggest that chemical similarity is a useful measure at the systems level, which would support phenotypic drug optimization efforts. With this study we demonstrate the potential of such integrated analysis approaches and suggest prioritizing further experiments to fill the gaps in the current data.

In order to improve undergraduates’ transfer of learning, professors changed teaching style from traditional lecture into problem-based, group discussion, practice doing, immediate use and critical thinking. Problem-based learning originated in the medical education. This kind of learning helped students build a team in order to solve the actual problems. Action learning emphasized the importance of “learning by doing” and “active construction”. They solved the real problems through critical thinking and reflection of team members. Therefore, the integration of problem-based learning and action learning was the new teaching trend. This paper explored the integration of problem-based learning and action learning in higher education. First of all, the fundamental concepts of problem-based learning and action learning were described. Secondly, the process of problem-based action learning were elaborated. The study also found out how to practice the problem-based action learning. Finally, feasible suggestions giving insight into

    To assure sustainability of our health systems and improve quality, implementing integrated wellness, health and social care service models have been proposed. They will need the enabling power of Health ICT facilitated systems and applications. Such solutions support the efficient coordination of service provision across provider and jurisdictional boundaries, the sharing of data, information and knowledge, and the streamlining as well as individualisation of care. Achieving such change in health systems with limited resources requires refocusing the trend of medico-technical progress. Health ICT innovations must be scrutinised for their potential to indeed contribute not only to decreasing costs, but - at the same time - improving the quality of life and ability to cope with challenges like the increasing prevalence of certain chronic diseases or new expectations from healthy people and patients alike. This paper argues that decision-oriented governance models leading to focused policy interventions are needed at several levels: Governments should provide for comprehensive Health ICT infrastructures to enable provider market success. At the individual actor level, sustainable business models reflecting in their value propositions the expectations of their clients (patients and funders) need to be developed. Health policy should design intelligent reimbursement systems providing incentives to indeed optimise services. Smart health innovations should only be implemented where they help achieve the goal of increasing the productivity of health value chains and the quality of overall service delivery value systems. To assure allocational efficiency, regulatory impact analyses (RIA) can support evidence based policy making.

    A statistical generalization of microeconomics has been made in Baaquie (2013), where the market price of every traded commodity, at each instant of time, is considered to be an independent random variable. The dynamics of commodity market prices is modeled by an action functional-and the focus of this paper is to empirically determine the action functionals for different commodities. The correlation functions of the model are defined using a Feynman path integral. The model is calibrated using the unequal time correlation of the market commodity prices as well as their cubic and quartic moments using a perturbation expansion. The consistency of the perturbation expansion is verified by a numerical evaluation of the path integral. Nine commodities drawn from the energy, metal and grain sectors are studied and their market behavior is described by the model to an accuracy of over 90% using only six parameters. The paper empirically establishes the existence of the action functional for commodity prices that was postulated to exist in Baaquie (2013).

  2. Actions for signature change

    This is a contribution on the controversy about junction conditions for classical signature change. The central issue in this debate is whether the extrinsic curvature on slices near the hypersurface of signature change has to be continuous ({\\it weak} signature change) or to vanish ({\\it strong} signature change). Led by a Lagrangian point of view, we write down eight candidate action functionals S_1,...S_8 as possible generalizations of general relativity and investigate to what extent each of these defines a sensible variational problem, and which junction condition is implied. Four of the actions involve an integration over the total manifold. A particular subtlety arises from the precise definition of the Einstein-Hilbert Lagrangian density |g|^{1/2} R[g]. The other four actions are constructed as sums of integrals over singe-signature domains. The result is that {\\it both} types of junction conditions occur in different models, i.e. are based on different first principles, none of which can be claimed t...

    Full Text Available A nonlinear multivariable control design with integral action is proposed and investigated for control of Exhaust Gas Recirculation (EGR and Variable Geometry Turbine (VGT in heavy duty Diesel engines. The main control goal is to regulate oxygen/fuel ratio and intake manifold EGR-fraction, and they are specified in an outer loop. These are chosen as main performance variables since they are strongly coupled to the emissions. An existing nonlinear control design based on feedback linearization is extended with integral action. In particular, the control design method utilizes a control Lyapunov function, inverse optimal control, and a nonlinear input transformation. Comparisons between different control structures are performed in simulations showing the following four points. Firstly, integral action is necessary to handle model errors so that the controller can track the performance variables specified in the outer loop. Secondly, the proposed control design handles the nonlinear effects in the Diesel engine that results in less control errors compared to a control structure with PID controllers. Thirdly, it is important to use the input transformation and it is sufficient to use a control structure with PID controllers and input transformation to handle the nonlinear effects. Fourthly, the proposed control design is sensitive to model errors in the input transformation while a control structure with PID controllers and input transformation handles these model errors. Une conception de régulation non linéaire à variables multiples avec action intégrée est proposée et étudiée pour une régulation de la Recirculation des Gaz d’Echappement (RGE et une Turbine à Géométrie Variable (TGV au sein de moteurs Diesel à usage industriel.

    2006-10-17

    A method for triggering an action of at least one downhole device on a downhole network integrated into a downhole tool string synchronized to an event comprises determining latency, sending a latency adjusted signal, and performing the action. The latency is determined between a control device and the at least one downhole device. The latency adjusted signal for triggering an action is sent to the downhole device. The action is performed downhole synchronized to the event. A preferred method for determining latency comprises the steps: a control device sends a first signal to the downhole device; after receiving the signal, the downhole device sends a response signal to the control device; and the control device analyzes the time from sending the signal to receiving the response signal.

  14. Wilsonian Effective Action of Superstring Theory

    CERN Document Server

    Sen, Ashoke

    2016-01-01

    By integrating out the heavy fields in type II or heterotic string field theory one can construct the effective action for the light fields. This effective theory inherits all the algebraic structures of the parent theory and the effective action automatically satisfies the Batalin-Vilkovisky quantum master equation. This theory is manifestly ultraviolet finite, has only light fields as its explicit degrees of freedom, and the Feynman diagrams of this theory reproduce the exact scattering amplitudes of light states in string theory to any arbitrary order in perturbation theory. Furthermore in this theory the degrees of freedom of light fields above certain energy scale are also implicitly integrated out. This energy scale is determined by a particular parameter labelling a family of equivalent actions, and can be made arbitrarily low, leading to the interpretation of the effective action as the Wilsonian effective action.

    By using integral forms we derive the superspace action of D=3, N=1 supergravity as an integral on a supermanifold. The construction is based on target space picture changing operators, here playing the role of Poincare' duals to the lower-dimensional spacetime surfaces embedded into the supermanifold.

    In this paper we investigate the use of action systems with differential actions in the specifcation of hybrid systems. As the main contribution we generalize the definition of a differential action, allowing the use of arbitrary relations over model variables and their time-derivatives...... in modelling continuous-time dynamics. The generalized differential action has an intuitively appealing predicate transformer semantics, which we show to be both conjunctive and monotonic. In addition, we show that differential actions blend smoothly with conventional actions in action systems, even under...... parallel composition. Moreover, as the strength of the action system formalism is the support for stepwise development by refinement, we investigate refinement involving a differential action. We show that, due to the predicate transformer semantics, standard action refinement techniques apply also...

  4. Different but complementary roles of action and gaze in action observation priming: Insights from eye- and motion-tracking measures

    Directory of Open Access Journals (Sweden)

    Clement eLetesson

    2015-05-01

    Full Text Available Action priming following action observation is thought to be caused by the observed action kinematics being represented in the same brain areas as those used for action execution. But, action priming can also be explained by shared goal representations, with compatibility between observation of the agent’s gaze and the intended action of the observer. To assess the contribution of action kinematics and eye gaze cues in the prediction of an agent’s action goal and action priming, participants observed actions where the availability of both cues was manipulated. Action observation was followed by action execution, and the congruency between the target of the agent’s and observer’s actions, and the congruency between the observed and executed action spatial location were manipulated. Eye movements were recorded during the observation phase, and the action priming was assessed using motion analysis. The results showed that the observation of gaze information influenced the observer’s prediction speed to attend to the target, and that observation of action kinematic information influenced the accuracy of these predictions. Motion analysis results showed that observed action cues alone primed both spatial incongruent and object congruent actions, consistent with the idea that the prime effect was driven by similarity between goals and kinematics. The observation of action and eye gaze cues together induced a prime effect complementarily sensitive to object and spatial congruency. While observation of the agent’s action kinematics triggered an object-centered and kinematic-centered action representation, independently, the complementary observation of eye gaze triggered a more fine-grained representation illustrating a specification of action kinematics towards the selected goal. Even though both cues differentially contributed to action priming, their complementary integration led to a more refined pattern of action priming.

    2010-01-01

    The principle of least action provides a holistic worldview in which nature in its entirety and every detail is pictured in terms of actions. Each and every action is ultimately composed of one or multiples of the most elementary action which corresponds to the Planck's constant. Elements of space are closed actions, known as fermions, whereas elements of time are open actions, known as bosons. The actions span energy landscape, the Universe which evolves irreversibly according to the 2nd law of thermodynamics by diminishing density differences in least time. During the step-by-step evolution densely-curled actions unfold by opening up and expelling one or multiple elementary actions to their surrounding sparser space. The manifold's varieties process from one symmetry group to another until the equivalence to their dual, i.e., the surrounding density has been attained. The scale-free physical portrayal of nature does not recognize any fundamental difference between fundamental particles and fundamental force...

    2016-05-01

    The planning and adjusting of one's actions in relation to an action partner is fundamental to smooth joint action. During their first years of life, children gradually become more engaged in joint actions. Here, we investigated whether and at what age children take their partner into account in their action plans to accommodate the other's actions. We focused on children's proactive planning (without prior experience) and flexible adjustment of action plans over time. In a behavioural study, we tested 96 children from four age groups (2½, 3, 3½ and 5 years) in a joint cup-stacking task. Children passed cups to their partner who had only one hand available (alternating over time) to build a tower. Children's response choices were assessed (i.e. passing the cup on the free or occupied side to their partner). The study yielded two major findings. At all ages, children proactively planned their actions in a way that accommodated their partner's actions. However, only by 3½ years did children start to flexibly integrate their partner into their action plans. Even at age 5, children only showed minimal adjustments to their action partner. Candidate processes underlying these developmental changes (e.g. inhibitory control, cognitive flexibility, perspective taking) are discussed. PMID:27069048

    We propose a holographic correspondence between the action integral I describing the mechanics of a finite number of degrees of freedom in the bulk, and the entropy S of the boundary (a holographic screen) enclosing that same volume. The action integral must be measured in units of (i times) Planck's constant, while the entropy must be measured in units of Boltzmann's constant. In this way we are led to an intriguing relation between the second law of thermodynamics and the uncertainty principle of quantum mechanics.

    We extend a conventional action system with a primitive action consisting of a differential equation and an evolution invariant. The semantics is given by a predicate transformer. The weakest liberal precondition is chosen, because it is not always desirable that steps corresponding to differential...... actions shall terminate. It is shown that the proposed differential action has a semantics which corresponds to a discrete approximation when the discrete step size goes to zero. The extension gives action systems the power to model real-time clocks and continuous evolutions within hybrid systems....

  17. Stochastic Lie group integrators

    Malham, Simon J A

    2007-01-01

    We present Lie group integrators for nonlinear stochastic differential equations with non-commutative vector fields whose solution evolves on a smooth finite dimensional manifold. Given a Lie group action that generates transport along the manifold, we pull back the stochastic flow on the manifold to the Lie group via the action, and subsequently pull back the flow to the corresponding Lie algebra via the exponential map. We construct an approximation to the stochastic flow in the Lie algebra via closed operations and then push back to the Lie group and then to the manifold, thus ensuring our approximation lies in the manifold. We call such schemes stochastic Munthe-Kaas methods after their deterministic counterparts. We also present stochastic Lie group integration schemes based on Castell--Gaines methods. These involve using an underlying ordinary differential integrator to approximate the flow generated by a truncated stochastic exponential Lie series. They become stochastic Lie group integrator schemes if...

After working out some auxiliary integrations involving Bessel and Whittaker functions, we arrive at the spectral expansion for t...

  20. Slimplectic Integrators: Variational Integrators for Nonconservative systems

    Tsang, David

    2016-05-01

    Symplectic integrators are widely used for long-term integration of conservative astrophysical problems due to their ability to preserve the constants of motion; however, they cannot in general be applied in the presence of nonconservative interactions. Here we present the “slimplectic” integrator, a new type of numerical integrator that shares many of the benefits of traditional symplectic integrators yet is applicable to general nonconservative systems. We utilize a fixed-time-step variational integrator formalism applied to a newly developed principle of stationary nonconservative action (Galley, 2013, Galley et al 2014). As a result, the generalized momenta and energy (Noether current) evolutions are well-tracked. We discuss several example systems, including damped harmonic oscillators, Poynting–Robertson drag, and gravitational radiation reaction, by utilizing our new publicly available code to demonstrate the slimplectic integrator algorithm. Slimplectic integrators are well-suited for integrations of systems where nonconservative effects play an important role in the long-term dynamical evolution. As such they are particularly appropriate for cosmological or celestial N-body dynamics problems where nonconservative interactions, e.g., gas interactions or dissipative tides, can play an important role.

We compare the zeta spectral action with the usual (cutoff based) spectral action and discuss its purely spectral origin, predictive power, stressing the importance of the issue of the three dimensionful fundamental constants, namely the cosmological constant, the Higgs vacuum expectation value, and the gravitational constant. We emphasize the fundamental role of the neutrino Majorana mass term for the structure of the bosonic action.

    2016-08-01

    The purpose of this study was to investigate the contribution of stereopsis to the processing of observed manipulative actions. To this end, we first combined the factors "stimulus type" (action, static control, and dynamic control), "stereopsis" (present, absent) and "viewpoint" (frontal, lateral) into a single design. Four sites in premotor, retro-insular (2) and parietal cortex operated specifically when actions were viewed stereoscopically and frontally. A second experiment clarified that the stereo-action-specific regions were driven by actions moving out of the frontoparallel plane, an effect amplified by frontal viewing in premotor cortex. Analysis of single voxels and their discriminatory power showed that the representation of action in the stereo-action-specific areas was more accurate when stereopsis was active. Further analyses showed that the 4 stereo-action-specific sites form a closed network converging onto the premotor node, which connects to parietal and occipitotemporal regions outside the network. Several of the specific sites are known to process vestibular signals, suggesting that the network combines observed actions in peripersonal space with gravitational signals. These findings have wider implications for the function of premotor cortex and the role of stereopsis in human behavior. PMID:27252350

    2015-01-01

    Despite the importance of the variational principles of physics, there have been relatively few attempts to consider them for a realistic framework. In addition to the old teleological question, this paper continues the recent discussion regarding the modal involvement of the principle of least action and its relations with the Humean view of the laws of nature. The reality of the possible paths in the principle of least action is examined from the perspectives of the contemporary metaphysics of modality and Leibniz's concept of the possibles striving from essence to existence. This paper introduces a model of a two-level modality based on an intuition that deep ontological connections exist between the possible paths in the principle of least action and possible quantum histories in the Feynman path integral. The proposed modal interpretation of the principle of least action replaces the classical representation of the system's motion along a single history in the actual modality by the simultaneous motions ...

    2014-01-01

    The classical, disembodied approach to music cognition conceptualizes action and perception as separate, peripheral processes. In contrast, embodied accounts of music cognition emphasize the central role of the close coupling of action and perception. It is a commonly established fact that perception spurs action tendencies. We present a theoretical framework that captures the ways in which the human motor system and its actions can reciprocally influence the perception of music. The cornerstone of this framework is the common coding theory, postulating a representational overlap in the brain between the planning, the execution, and the perception of movement. The integration of action and perception in so-called internal models is explained as a result of associative learning processes. Characteristic of internal models is that they allow intended or perceived sensory states to be transferred into corresponding motor commands (inverse modeling), and vice versa, to predict the sensory outcomes of planned actions (forward modeling). Embodied accounts typically refer to inverse modeling to explain action effects on music perception (Leman, 2007). We extend this account by pinpointing forward modeling as an alternative mechanism by which action can modulate perception. We provide an extensive overview of recent empirical evidence in support of this idea. Additionally, we demonstrate that motor dysfunctions can cause perceptual disabilities, supporting the main idea of the paper that the human motor system plays a functional role in auditory perception. The finding that music perception is shaped by the human motor system and its actions suggests that the musical mind is highly embodied. However, we advocate for a more radical approach to embodied (music) cognition in the sense that it needs to be considered as a dynamical process, in which aspects of action, perception, introspection, and social interaction are of crucial importance.

The cornerstone of this framework is the common coding theory postulating a representational overlap in the brain between the planning, the execution, and the perception of movement. The integration of action and perception in so-called internal models is explained as a result of associative learning processes. Characteristic of internal models is that they allow intended or perceived sensory states to be transferred into corresponding motor commands (inverse modelling, and vice versa, to predict the sensory outcomes of planned actions (forward modelling. Embodied accounts typically adhere to inverse modelling to explain action effects on music perception (Leman, 2007. We extent this account by pinpointing forward modelling as an alternative mechanism by which action can modulate perception. We provide an extensive overview of recent empirical evidence in support of this idea. Additionally, we demonstrate that motor dysfunctions can cause perceptual disabilities, supporting the main idea of the paper that the human motor system plays a functional role in auditory perception. The finding that music perception is shaped by the human motor system, and the action it produces, suggests that the musical mind is highly embodied. However, we advocate for a more radical approach to embodied (music cognition in the sense that it needs to be considered as a dynamic process, in which aspects of action, perception, introspection, and social interaction are of crucial

  1. Five Computational Actions in Information Processing

    Directory of Open Access Journals (Sweden)

    2014-12-01

    Full Text Available This study is circumscribed to the Information Science. The zetetic aim of research is double: a to define the concept of action of information computational processing and b to design a taxonomy of actions of information computational processing. Our thesis is that any information processing is a computational processing. First, the investigation trays to demonstrate that the computati onal actions of information processing or the informational actions are computationalinvestigative configurations for structuring information: clusters of highlyaggregated operations which are carried out in a unitary manner operate convergent and behave like a unique computational device. From a methodological point of view, they are comprised within the category of analytical instruments for the informational processing of raw material, of data, of vague, confused, unstructured informational elements. As internal articulation, the actions are patterns for the integrated carrying out of operations of informational investigation. Secondly, we propose an inventory and a description of five basic informational computational actions: exploring, grouping, anticipation, schematization, inferential structuring. R. S. Wyer and T. K. Srull (2014 speak about "four information processing". We would like to continue with further and future investigation of the relationship between operations, actions, strategies and mechanisms of informational processing.

    We show that any continuous partial action on a topological space has a unique enveloping action, i.e. it is the restriction of a global action. In the case of C^*-algebras we prove that any partial action has an enveloping action up to Morita equivalence. The study of enveloping actions up to Morita equivalence reveals the form that Takai duality takes for partial actions.

  5. Action spectra again?

    Science.gov (United States)

    Coohill, T P

    1991-11-01

    Action spectroscopy has a long history and is of central importance to photobiological studies. Action spectra were among the first assays to point to chlorophyll as the molecule most responsible for plant growth and to DNA as the genetic material. It is useful to construct action spectra early in the investigation of new areas of photobiological research in an attempt to determine the wavelength limits of the radiation region causing the studied response. But due to the severe absorption of ultraviolet (UV) radiation by biological samples, UV action spectra were first limited to small cells (bacteria and fungi). Advances in techniques (e.g. single cell culture) and analysis allowed accurate action spectra to be reported even for mammalian cells. But precise analytical action spectra are often difficult to obtain when large, pigmented, or groups of cells are investigated. Here some action spectra are limited in interpretation and merely supply a wavelength vs effect curve. When polychromatic sources are employed, the interpretation of action spectra is even more complex and formidable. But such polychromatic action spectra can be more directly related to ambient responses. Since precise action spectra usually require the completion of a relatively large number of careful experiments using somewhat sophisticated equipment over a range of at least six wavelengths, they are often not pursued. But they remain central to the elucidation of the effect being studied. The worldwide community has agreed that stratospheric ozone is depleting, with the possibility of a consequent rise in the amount of UV-B (290-320 nm) reaching the earth's surface. It is therefore essential that new action spectra be completed for UV-B effects on a large variety of responses of human, animal, and aquatic plant systems. Combining these action spectra with the known amounts of UV-B reaching the biosphere can give rise to solar UV effectiveness spectra that, in turn, can give rise to estimates

  7. Reasoning about Unreliable Actions

    CERN Document Server

    White, Graham

    2012-01-01

    We analyse the philosopher Davidson's semantics of actions, using a strongly typed logic with contexts given by sets of partial equations between the outcomes of actions. This provides a perspicuous and elegant treatment of reasoning about action, analogous to Reiter's work on artificial intelligence. We define a sequent calculus for this logic, prove cut elimination, and give a semantics based on fibrations over partial cartesian categories: we give a structure theory for such fibrations. The existence of lax comma objects is necessary for the proof of cut elimination, and we give conditions on the domain fibration of a partial cartesian category for such comma objects to exist.

  15. 'Action 2016': AREVA's strategic action plan

    International Nuclear Information System (INIS)

    On December 13, 2011, Luc Oursel, CEO, and Pierre Aubouin, Chief Financial Officer presented the group's strategic plan for the period 2012-2016. The plan has been drawn up collectively and is based on a thorough-going analysis and a realistic assessment of perspectives for all group activities and associated resources. Development of nuclear and renewable energies: the fundamentals are unchanged. In this context, the German decision remains an isolated case and the great majority of nuclear programs around the world have been confirmed. More conservative in its projections than the International Energy Agency, the group expects growth of 2.2% annually, reaching 583 GW of installed nuclear capacity by 2030, against 378 GW today. However, the Fukushima accident will lead to delays in launching new programs. 'Action 2016' plan aims to consolidate AREVA's leadership in nuclear energy and become a leading player in renewable energy. The group's strategic action plan 'Action 2016' is based on the following strategic choices: - commercial priority given to value creation, - selectivity in investments, - strengthening of the financial structure. These demand an improvement in the group's performance by 2015. This plan makes nuclear safety a strategic priority for the industrial and commercial performance of the group. This ambitious performance plan for the period 2012-2016 will give the group the wherewithal to withstand a temporary slowdown in the market resulting from the Fukushima accident and to deliver safe and sustainable growth of the business. The plan sets out the strategic direction for the group's employees for the years ahead: taking advantage of the expected growth in nuclear and renewable energies, targeted investment programs, and return to self-financing as of 2014

  16. Commitment to action. Population Action International.

    Science.gov (United States)

    Squires, S

    1994-01-01

    The national chair of Population Action International (formerly the Population Crisis Committee), Robin Chandler Duke, is a crusader for women's reproductive rights. She was in Bangladesh in 1971 during its civil war. Soldiers would rape young Muslim women, and their families would reject them when they became pregnant. The head of the exiled government agreed to let physicians from IPPF perform abortions on these women, which allowed families to take them back. Opposition to the abortions arose, however. This experience in Bangladesh sparked Ms. Duke's interest in population control. Her years as the wife of a US diplomat granted her access to powerful people worldwide. Her predecessor, retired US Army General Bill Draper, called Ms. Duke from his death bed in 1974 to ask her to be national chair of PAI. She served as a delegate in various international meetings, e.g., the 1980 UNESCO meetings in Belgrade. Spain and Luxembourg honored her for her work of campaigning for women's reproductive rights. She believes that rapid population growth is the most significant problem in the world today. It exacerbates poverty, environmental destruction, and political instability. She believes that universal availability of high quality, voluntary family planning services, including safe abortion, is needed to save humanity from the vicious cycle. Since family planning, sex education, and abortion are the most personal and sensitive parts of people's lives, Population Action frames family planning in the context of basic health care. AIDS complicates the issue, because contraception is no longer limited to birth control. Even though the organization realizes that sexual abstinence is the best way to avoid AIDS, it tries to educate female teenagers not to let boys coerce them to have sex. If they do, have sex Population Action advocates condom use. Ms. Duke cites the family planning successes of Indonesia, Zimbabwe, and Thailand.

  17. The effective action in four-dimensional CDT

    CERN Document Server

    Gizbert-Studnicki, Jakub

    2015-01-01

    We present recent results concerning the measurement and analysis of the effective action in four-dimensional Causal Dynamical Triangulations. The action describes quantum fluctuations of the spatial volume of the CDT universe (or alternatively the scale factor) after integrating out other degrees of freedom. We use the covariance of volume fluctuations to measure and parametrize the effective action inside the de Sitter phase, also called the C phase. We show that the action is consistent with a simple discretization of the minisuperspace action (with a reversed overall sign). We discuss possible subleading corrections and show how to construct a more complicated effective action comprising both integer and half-integer discrete proper time layers. We introduce a new method of the effective action measurement based on the transfer matrix. We show that the results of the new method are fully consistent with the covariance matrix method inside the de Sitter phase. We use the new method to measure the effective...

  2. Nonplanar integrability

    Carlson, Warren; de Mello Koch, Robert; Lin, Hai

    2011-03-01

    In this article we study operators with a dimension Δ ˜ O( N) and show that simple analytic expressions for the action of the dilatation operator can be found. The operators we consider are restricted Schur polynomials. There are two distinct classes of operators that we consider: operators labeled by Young diagrams with two long columns or two long rows. The main complication in working with restricted Schur polynomials is in building a projector from a given S n+ m irreducible representation to an S n × S m irreducible representation (both specified by the labels of the restricted Schur polynomial). We give an explicit construction of these projectors by reducing it to the simple problem of addition of angular momentum in ordinary non-relativistic quantum mechanics. The diagonalization of the dilatation operator reduces to solving three term recursion relations. The fact that the recursion relations have only three terms is a direct consequence of the weak mixing at one loop of the restricted Schur polynomials. The recursion relations can be solved exactly in terms of symmetric Kravchuk polynomials or in terms of Clebsch-Gordan coefficients. This proves that the dilatation operator reduces to a decoupled set of harmonic oscillators and therefore it is integrable.

  3. Virtual action and real action have different impacts on comprehension of concrete verbs.

    Science.gov (United States)

    Repetto, Claudia; Cipresso, Pietro; Riva, Giuseppe

    2015-01-01

    In the last decade, many results have been reported supporting the hypothesis that language has an embodied nature. According to this theory, the sensorimotor system is involved in linguistic processes such as semantic comprehension. One of the cognitive processes emerging from the interplay between action and language is motor simulation. The aim of the present study is to deepen the knowledge about the simulation of action verbs during comprehension in a virtual reality setting. We compared two experimental conditions with different motor tasks: one in which the participants ran in a virtual world by moving the joypad knob with their left hand (virtual action performed with their feet plus real action performed with the hand) and one in which they only watched a video of runners and executed an attentional task by moving the joypad knob with their left hand (no virtual action plus real action performed with the hand). In both conditions, participants had to perform a concomitant go/no-go semantic task, in which they were asked to press a button (with their right hand) when presented with a sentence containing a concrete verb, and to refrain from providing a response when the verb was abstract. Action verbs described actions performed with hand, foot, or mouth. We recorded electromyography (EMG) latencies to measure reaction times of the linguistic task. We wanted to test if the simulation occurs, whether it is triggered by the virtual or the real action, and which effect it produces (facilitation or interference). Results underlined that those who virtually ran in the environment were faster in understanding foot-action verbs; no simulation effect was found for the real action. The present findings are discussed in the light of the embodied language framework, and a hypothesis is provided that integrates our results with those in literature.

  4. Action Principle for Potential Flows

    CERN Document Server

    Frønsdal, Christian

    2014-01-01

    The restriction of hydrodynamics to non-viscous, potential (gradient, irrotational) flows is a theory both simple and elegant; a favorite topic of introductory textbooks. It is known that this theory (under the stated limitations) can be formulated as an action principle. It finds its principle application to adiabatic systems and cannot account for viscosity or dissipation. However, it can be generalized to include non-potential flows, as this paper shows. The new theory is a combination of Eulerian and Lagrangian hydrodynamics, with an extension to thermodynamics. It describes adiabatic phenomena but does not account for viscosity or dissipation. Nevertheless, it is an approach within which quasi-static processes can be described. In the adiabatic context it appears to be an improvement of the Navier-Stokes equation, the principal advantage being a natural concept of energy in the form of a first integral of the motion, conserved by virtue of the Euler-Lagrange equations.

    CERN Document Server

    Tsang, David; Stein, Leo C; Turner, Alec

    2015-01-01

    Symplectic integrators are widely used for long-term integration of conservative astrophysical problems due to their ability to preserve the constants of motion; however, they cannot in general be applied in the presence of nonconservative interactions. In this Letter, we develop the "slimplectic" integrator, a new type of numerical integrator that shares many of the benefits of traditional symplectic integrators yet is applicable to general nonconservative systems. We utilize a fixed time-step variational integrator formalism applied to the principle of stationary nonconservative action developed in Galley, 2013; Galley, Tsang & Stein, 2014. As a result, the generalized momenta and energy (Noether current) evolutions are well-tracked. We discuss several example systems, including damped harmonic oscillators, Poynting-Robertson drag, and gravitational radiation reaction, by utilizing our new publicly available code to demonstrate the slimplectic integrator algorithm. Slimplectic integrators are well-suite...

  6. Symplectic Analysis of the Two Dimensional Palatini Action

    CERN Document Server

    McKeon, D G C

    2016-01-01

    The symplectic analysis, initiated by Faddeev and Jackiw, is applied to the first order (Palatini) form of the Einstein-Hilbert action in 1+1 dimensions. The constraints that arise are shown to result in the same gauge transformations that follow from the first class constraints occurring when the Dirac constraint formalism is applied to this action. When the symplectic formalism is used to quantize the action in conjunction with the path integral it does not appear to be possible to recover the Faddeev-Popov form of the path integral when using a covariant gauge fixing, or if the gauge fixing choices have non-vanishing Poisson Brackets.

  7. Interweaving reason, action, and perception

    Science.gov (United States)

    Fennema, Claude L., Jr.

    1992-11-01

    In an attempt to understand and emulate intelligent behavior Artificial Intelligence researchers have, for the most part, taken a reductionist approach and divided their investigation into separate studies of reason, perception, and action. As a consequence, intelligent robots have been constructed using a coarse grained architecture; reasoning, perception, and action have been implemented as separate modules that interact infrequently. This paper describes an investigation into the effect of reducing this architecture granularity on the computational efficiency of the overall system. It demonstrates that introducing a fine grained integration or `interweaving' of these functions can result in significant complexity reduction. This paper introduces the `reason a little, move a little, look a little,' or RML paradigm, describes an RML navigation system, and discusses analytical and experimental results that quantify complexity reduction for planning and vision. The system details illustrate novel approaches to representation, planning, and vision. The environment is represented as a network that provides mechanisms for coping with positional uncertainty and focusing reasoning activities. Plans are constructed in three dimensions using a geometry-induced hierarchical decomposition. The approach to vision takes its lead from the way a blind man uses his cane: to verity that reason is consistent with reality.

  9. A reasoned action approach to health promotion.

    Science.gov (United States)

    Fishbein, Martin

    2008-01-01

    This article describes the integrative model of behavioral prediction (IM), the latest formulation of a reasoned action approach. The IM attempts to identify a limited set of variables that can account for a considerable proportion of the variance in any given behavior. More specifically, consistent with the original theory of reasoned action, the IM assumes that intentions are the immediate antecedents of behavior, but in addition, the IM recognizes that environmental factors and skills and abilities can moderate the intention-behavior relationship. Similar to the theory of planned behavior, the IM also assumes that intentions are a function of attitudes, perceived normative pressure and self-efficacy, but it views perceived normative pressure as a function of descriptive as well as of injunctive (i.e., subjective) norms. After describing the theory and addressing some of the criticisms directed at a reasoned action approach, the paper illustrates how the theory can be applied to understanding and changing health related behaviors.

    Full Text Available The effort in this work to elaborate an action research method as a central research problem considering the recent contemporary sociological and educa­tional literature. The author begins with the statement that the method is a complex notion, composed of three main components: approach to the research problem, data gathering procedures and data analysis procedures. This point of view is further applied and elaborated in the author's text, emphasizing the action research characteristics: interruption with the positive tradition in social research and the divided of the objective and subjective, application of the qualitative data. The sub­stantial difference between the action research in regard with the other kinds of research, is not only in getting to new knowledge's, but also in problem solving or a change in the situation in a concrete social context.

    Moore, Angela R; Buchanan, Natasha D; Fairley, Temeika L; Lee Smith, Judith

    2015-12-01

    Long-term objectives associated with cancer survivors have been suggested by Healthy People 2020, including increasing the proportion of survivors living beyond 5 years after diagnosis and improving survivors' mental and physical health-related quality of life. Prior to reaching these objectives, several intermediate steps must be taken to improve the physical, social, emotional, and financial well-being of cancer survivors. Public health has a role in developing strategic, actionable, and measurable approaches to facilitate change at multiple levels to improve the lives of survivors and their families. The social ecological model has been used by the public health community as the foundation of multilevel intervention design and implementation, encouraging researchers and practitioners to explore methods that promote internal and external changes at the individual, interpersonal, organizational, community, and policy levels. The survivorship community, including public health professionals, providers, policymakers, survivors, advocates, and caregivers, must work collaboratively to identify, develop, and implement interventions that benefit cancer survivors. The National Action Plan for Cancer Survivorship highlights public health domains and associated strategies that can be the impetus for collaboration between and among the levels in the social ecological model and are integral to improving survivor outcomes. This paper describes the Public Health Action Model for Cancer Survivorship, an integrative framework that combines the National Action Plan for Cancer Survivorship with the social ecological model to demonstrate how interaction among the various levels may promote better outcomes for survivors.

  17. The Climate Change Action Plan: Technical supplement

    Energy Technology Data Exchange (ETDEWEB)

    1994-03-01

    This Technical Annex documents the assumptions and parameters used in developing the supporting analysis for the Climate Change Action Plan (the Plan) issued by President Clinton on October 19, 1993. The Annex is intended to meet the needs of independent energy and environmental analysts who wish to better understand the Plan, its analytical underpinnings, and the events that need to transpire for the emissions reductions called for in the Plan to be realized. The Plan documented in this Annex reflects the outcome of a wide-ranging effort by Government agencies and interested members of the public to develop and implement actions that can reduce net greenhouse gas emissions in the year 2000 to their aggregate 1990 level. Based on agency and public input, the Climate Change Mitigation Group, chaired by the White House Office on Environmental Policy, developed the Plan`s content. Many of the actions called for in the Plan are now underway, while others are in advanced planning pending congressional action on the fiscal year 1995 budget. The analysis supporting the Plan represents the results of an interagency effort. The US Department of Energy (DOE) was responsible for the integrated analysis of energy-related options, based on the analysis of individual energy-related options by DOE, the US Environmental Protection Agency (EPA), and the US Department of Transportation (DOT). EPA led in providing analysis for actions related to methane, hydrofluorocarbons, and perfluorocarbons. The US Department of Agriculture (USDA) led the analysis of carbon sequestration actions and cooperated with EPA in the analysis of actions to reduce nitrous oxide emissions.

  9. Finding minimal action sequences with a simple evaluation of actions

    Directory of Open Access Journals (Sweden)

    Ashvin eShah

    2014-11-01

    Full Text Available Animals are able to discover the minimal number of actions that achieves an outcome (the minimal action sequence. In most accounts of this, actions are associated with a measure of behavior that is higher for actions that lead to the outcome with a shorter action sequence, and learning mechanisms find the actions associated with the highest measure. In this sense, previous accounts focus on more than the simple binary signal of ``was the outcome achieved?''; they focus on ``how well was the outcome achieved?'' However, such mechanisms may not govern all types of behavioral development. In particular, in the process of action discovery (Redgrave and Gurney, 2006, actions are reinforced if they simply lead to a salient outcome because biological reinforcement signals occur too quickly to evaluate the consequences of an action beyond an indication of the outcome's occurrence. Thus, action discovery mechanisms focus on the simple evaluation of ``was the outcome achieved?'' and not ``how well was the outcome achieved?'' Notwithstanding this impoverishment of information, can the process of action discovery find the minimal action sequence? We address this question by implementing computational mechanisms, referred to in this paper as no-cost learning rules, in which each action that leads to the outcome is associated with the same measure of behavior. No-cost rules focus on ``was the outcome achieved?'' and are consistent with action discovery. No-cost rules discover the minimal action sequence in simulated tasks and execute it for a substantial amount of time. Extensive training, however, results in extraneous actions, suggesting that a separate process (which has been proposed in action discovery must attenuate learning if no-cost rules participate in behavioral development. We describe how no-cost rules develop behavior, what happens when attenuation is disrupted, and relate the new mechanisms to wider computational and biological context.

  10. Archetypes as action patterns.

    Hogenson, George B

    2009-06-01

    The discovery of mirror neurons by researchers at the University of Parma promises to radically alter our understanding of fundamental cognitive and affective states. This paper explores the relationship of mirror neurons to Jung's theory of archetypes and proposes that archetypes may be viewed as elementary action patterns. The paper begins with a review of a proposed interpretation of the fainting spells of S. Freud in his relationship with Jung as an example of an action pattern that also defines an archetypal image. The challenge that mirror neurons present to traditional views in analytical psychology and psychoanalysis, however, is that they operate without recourse to a cognitive processing element. This is a position that is gaining increasing acceptance in other fields as well. The paper therefore reviews the most recent claims made by the Boston Process of Change Study Group as well as conclusions drawn from dynamic systems views of development and theoretical robotics to underline the conclusion that unconscious agency is not a requirement for coherent action. It concludes with the suggestion that this entire body of research may lead to the conclusion that the dynamic unconscious is an unnecessary hypothesis in psychoanalysis and analytical psychology.

  16. Climate Change Adaptation Actions in Tirana

    Directory of Open Access Journals (Sweden)

    JAMARBER MALLTEZI

    2015-06-01

    Full Text Available Tirana has recently experienced changing weather patterns such as rising temperatures and occurrence of extreme weather events. Such events – in combination with a rapid increase of urban areas and impermeable cement covering the natural soil in the city – have caused increased flooding, riverside erosion, delayed traffic, increased spending for cooling during the summer, increased need for health services, and an urgent need to plan the city smartly. Tirana is preparing a set of Climate Change Adaptation Actions in order to manage the posed risks and adapt to climate change. The city administration should integrate climate change adaptation in their management and planning processes. This exercise was prepared by using the Climate Compass tool and included the vulnerability assessment of different sectors in the city, evaluated the risks posed to vulnerable target groups and proposed feasible adaptation options. It outlines mostly actions to be taken to manage risks and build climate resilience across essential public infrastructure and services. Such actions would require better land use planning to maintain – and where possible increase – the natural areas and leave the natural soil undisturbed. Key to success is integrating adaptation concepts into the city planning and development investments. The result is a novel approach and guidance to better integrate adaptation concepts in city planning and new technologies to prevent heat waves, flood risks in the city, etc.Administrators of the Tirana Municipality should keep in mind and integrate the climate change adaptationactions into daily planning and decision making for several sectors including urban planning, transport, public services, water infrastructure, emergency response, etc. in order to ensure sustainable development for the city.

    Following Title VII's enactment, group-based employment discrimination actions flourished due to disparate impact theory and the class action device. Courts recognized that subordination that defined a group's social identity was also sufficient legally to bind members together, even when relief had to be issued individually. Woven through these cases was a notion of panethnicity that united inherently unrelated groups into a common identity, for example, Asian Americans. Stringent judicial interpretation subsequently eroded both legal frameworks and it has become increasingly difficult to assert collective employment actions, even against discriminatory practices affecting an entire group. This deconstruction has immensely disadvantaged persons with disabilities. Under the Americans with Disabilities Act (ADA), individual employee claims to accommodate specific impairments, such as whether to install ramps or replace computer screens, have all but eclipsed a coherent theory of disability-based disparate impact law. Moreover, the class action device has been virtually nonexistent in disability discrimination employment cases. The absence of collective action has been especially harmful because the realm of the workplace is precisely where group-based remedies are needed most. Specifically, a crucial but overlooked issue in disability integration is the harder-to-reach embedded norms that require job and policy modifications. The Article argues that pandisability theory serves as an analogue to earlier notions of panethnicity and provides an equally compelling heuristic for determining class identity. It shows that pandisability undergirds ADA public service and public accommodation class actions in which individualized remedy assessments have been accepted as part of group-based challenges to social exclusion. The Article also demonstrates that this broader vision of collective action is consistent with the history underlying the class action device. Taking

    Wrongful birth actions aim to compensate litigants who are negligently deprived by health professionals of their right to reproductive choice. Access to safe and legal abortion is integral to the action and wrongful birth claims in the United Kingdom have been facilitated by the Abortion Act 1967 (as amended). The recent Australian case CES v Superclinics (1995) 38 NSWLR 47 shows how judicial confusion about the legality of abortion can result in judges condoning medical negligence. The Super...

    We present a computational approach to radical rhetoric that leverages the co-expression of rhetoric and action features in discourse to identify violent intent. The approach combines text mining and machine learning techniques with insights from Frame Analysis and theories that explain the emergence of violence in terms of moral disengagement, the violation of sacred values and social isolation in order to build computational models that identify messages from terrorist sources and estimate their proximity to an attack. We discuss a specific application of this approach to a body of documents from and about radical and terrorist groups in the Middle East and present the results achieved.

  10. Improved motion description for action classification

    Directory of Open Access Journals (Sweden)

    Mihir eJain

    2016-01-01

    Full Text Available Even though the importance of explicitly integrating motion characteristics in video descriptions has been demonstrated by several recent papers on action classification, our current work concludes that adequately decomposing visual motion into dominant and residual motions, i.e.: camera and scene motion, significantly improves action recognition algorithms. This holds true both for the extraction of the space-time trajectories and for computation of descriptors.We designed a new motion descriptor – the DCS descriptor – that captures additional information on local motion patterns enhancing results based on differential motion scalar quantities, divergence, curl and shear features. Finally, applying the recent VLAD coding technique proposed in image retrieval provides a substantial improvement for action recognition. These findings are complementary to each other and they outperformed all previously reported results by a significant margin on three challenging datasets: Hollywood 2, HMDB51 and Olympic Sports as reported in (Jain et al. (2013. These results were further improved by (Oneata et al. (2013; Wang and Schmid (2013; Zhu et al. (2013 through the use of the Fisher vector encoding. We therefore also employ Fisher vector in this paper and we further enhance our approach by combining trajectories from both optical flow and compensated flow. We as well provide additional details of DCS descriptors, including visualization. For extending the evaluation, a novel dataset with 101 action classes, UCF101, was added.

  11. Screening action potentials: The power of light

    Lars eKaestner

    2011-07-01

    Full Text Available Action potentials reflect the concerted activity of all electrogenic constituents in the plasma membrane during the excitation of a cell. Therefore, the action potential is an integrated readout and a promising parameter to detect electrophysiological failures or modifications thereof in diagnosis as well as in drug screens. Cellular action potentials can be recorded by optical approaches. To fulfill the pre-requirements to scale up for e.g. pharmacological screens the following preparatory work has to be provided: (i model cells under investigation need to represent target cells in the best possible manner; (ii optical sensors that can be either small molecule dyes or genetically encoded potential probes need to provide a reliable readout with minimal interaction with the naive behavior of the cells and (iii devices need to be capable to stimulate the cells, read out the signals with the appropriate speed as well as provide the capacity for a sufficient throughput. Here we discuss several scenarios for all three categories in the field of cardiac physiology and pharmacology and provide a perspective to use the power of light in screening cardiac action potentials.

  20. Infants’ understanding of object-directed action: An interdisciplinary synthesis

    Directory of Open Access Journals (Sweden)

    Scott J. Robson

    2016-02-01

    Full Text Available Recognizing that the object-directed actions of others are governed by goals and intentions is a crucial component of human interaction. These actions often occur rapidly and without explanation, yet we learn from and predict the actions of others with remarkable speed and accuracy, even during the first year of life. This review paper will serve as a bridge between several disparate literatures that, we suggest, can each contribute to our understanding of how infants interpret action. Specifically, we provide a review not just of research on infant goal attribution per se, but also incorporate findings from studies on the mirror neuron system and infant object cognition. The integration of these various research approaches allows for a novel construal of the extents and limits of early goal attribution -- one in which the importance of the entire action context is considered -- and points to specific future research directions.

    this report describes a digital integrator in which, by means of digital signal processing, the integral of the input signal is determined continuously. This integrator is a prototype of a, to be constructed, faster integrator which has to integrate fast pulses originating from a detector setup. The prototype operates with a maximum sampling frequency of 40 MHz. By some extension this can be enhanced up to about 70 MHz. Finally an integrator is intended with a sampling frequency of 1 GHz. By means of the prototype the principal operation of the integrator, an extended description of the constructed prototype is given followed by measurements at the prototype and the analysis of the results.

  4. Remedial action technology - arid

    International Nuclear Information System (INIS)

    A summary is presented of the low-level waste remedial action program at Los Alamos. The experimental design and progress is described for the experiments on second generation intrusion barriers, subsidence effects on SLB components, moisture cycling effects on chemical transport, and erosion control methodologies. The soil moisture data from the bio-intrusion and moisture cycling experiments both demonstrate the overwhelming importance of vegetation in minimizing infiltration of water through trench covers and backfill. Evaporation, as a water loss component in trench covers, is only effective in reducing soil moisture within 40 cm of the trench cover surface. Moisture infiltrating past the zone of evaporation in unvegetated or poorly vegetated trench covers is in storage and accumulates until drainage out of the soil profile occurs. Judicious selection of vegetation species for revegetating a low-level waste site may prevent infiltration of moisture into the trench and, when coupled with other design features (i.e. trench cover slope, tilling and seeding practice), may greatly reduce problems with erosion. Standard US Department of Agriculture erosion plots, when coupled with a state-of-the-art water balance and erosion model (CREAMS) promises to be highly useful in screening proposed remedial action cover designs for low-level waste sites. The erosion plot configuration allows for complete accounting of the water balance in a soil profile. This feature enables the user to optimize cover designs to minimize erosion and infiltration of water into the trench

    2015-08-01

    Resveratrol, a natural polyphenol found in grapes, berries, and medicinal plants, exhibits antioxidant and anti-inflammatory activities and has been proposed to be a longevity-prolonging agent. There is also growing evidence that resveratrol has cardioprotective properties and beneficial effects on both glucose and lipid metabolism. Recently, several studies have examined the use of resveratrol as a therapeutic agent to treat numerous pathological and metabolic disorders. Herein, we present insights into the mechanisms of action, biological effects, and current evidence of actions of resveratrol on the ovary. In vitro, resveratrol inhibits proliferation and androgen production by theca-interstitial cells. Resveratrol also exerts a cytostatic, but not cytotoxic, effect on granulosa cells, while decreasing aromatization and vascular endothelial growth factor expression. In vivo, resveratrol treatment reduced the size of adipocytes and improved estrus cyclicity in the previously acyclic rat model of polycystic ovary syndrome (PCOS). In addition, resveratrol increased the ovarian follicular reserve and prolonged the ovarian life span in rats. Taken together, resveratrol emerges as a potential therapeutic agent to treat conditions associated with androgen excess, such as PCOS. The efficacy of resveratrol in the treatment of gynecological conditions requires further investigation. PMID:26315293

  6. Ontario's energy action plan

    International Nuclear Information System (INIS)

    In the fall of 2002, the government of Ontario announced an action plan designed to ensure stable electricity prices while additional electricity generating capacity is built. The action plan included a strategy for encouraging major private sector investments in wind, solar and other renewable energy sources. The strategies for new renewable energy projects include: property tax incentives, business income tax incentives, and sales tax rebates. Initiatives to increase supply include: Toronto's Portland 550 megawatt, natural gas-fired generating station, Niagara Falls' Beck Tunnel Project, and Windsor's 580 megawatt natural gas-fired generating station. The government is promoting energy conservation by reducing its electricity consumption by 10 per cent, and setting a target where 20 per cent of electricity consumed in the province must be from renewable energy sources. The use of interval meters by Ontario residents is being encouraged. A provincial sales tax rebate is being offered to customers buying select energy efficient appliances. In its commitment to environmental protection, the Ontario government is phasing out coal, offering rebates for solar energy systems, implementing measures to reduce acid rain, and investing $3.25 billion over ten years to renew and expand public transit. In Chatham, Ontario, a plant producing ethanol from corn was built, and others are planned for other parts of the province. Tax incentives are also offered for alternative fuel users. 1 ref., 1 tab

    The consideration of dynamic processes becomes more and more important on investigations of building heating plants, because of their influence on the economics, but also on the determination of an energy-optimal operation of such a system. For practical considerations of counter-clockwise operated heat exchanger model with known system parameters has been extracted for the theoretical investigations. The first part of this contribution deals with the functionalism and the action of the proposed numerical methods (the kind of finite differencing-scheme, grid spacing of time and space). The second part belongs to the results of the system performance of the technical component.

  13. The minimalist grammar of action.

    Pastra, Katerina; Aloimonos, Yiannis

    2012-01-12

    Language and action have been found to share a common neural basis and in particular a common 'syntax', an analogous hierarchical and compositional organization. While language structure analysis has led to the formulation of different grammatical formalisms and associated discriminative or generative computational models, the structure of action is still elusive and so are the related computational models. However, structuring action has important implications on action learning and generalization, in both human cognition research and computation. In this study, we present a biologically inspired generative grammar of action, which employs the structure-building operations and principles of Chomsky's Minimalist Programme as a reference model. In this grammar, action terminals combine hierarchically into temporal sequences of actions of increasing complexity; the actions are bound with the involved tools and affected objects and are governed by certain goals. We show, how the tool role and the affected-object role of an entity within an action drives the derivation of the action syntax in this grammar and controls recursion, merge and move, the latter being mechanisms that manifest themselves not only in human language, but in human action too.

    During the 1980s, 1990s and early 2000s,various intercultural health proposals and actions emerged in most Latin American countries. These initiatives aimed to integrate biomedicine with traditional medicine based on 'parallel' relationships, as opposed relationships based on exclusion, subordination and hegemony. These initiatives had two basic objectives:1) to contribute to the cultural rehabilitation of ethnic groups that made effective use of traditional medicine; and 2) to improve the quality of relationships between health professionals and indigenous patients. This paper analyzes the reasons for the limited impact and, in some cases, failure of such intercultural health initiatives. PMID:26816169

    2008-01-01

    Telomerase has fundamental roles in bypassing cellular aging and in cancer progression by maintaining telomere homeostasis and integrity. However, recent studies have led some investigators to suggest novel biochemical properties of telomerase in several essential cell signaling pathways without apparent involvement of its well established function in telomere maintenance. These observations may further enhance our understanding of the molecular actions of telomerase in aging and cancer. This review will provide an update on the extracurricular activities of telomerase in apoptosis, DNA repair, stem cell function, and in the regulation of gene expression.

The four energy strategies selected are: (1) expanding public outreach on energy efficiency and conservation, (2) establishing a demand-side management revolving loan program, (3) exploring waste-to-energy options, and (4) influencing the transportation sector via anti-idling legislation, vehicle registration fees, and electric vehicles.

  18. Networks for Collective Action

    CERN Document Server

    Bruggeman, Jeroen

    2016-01-01

    A significant challenge is to explain how people cooperate for public goods. The problem is more difficult for people when their public good and its benefits are unclear at the outset and its timing and costs are uncertain. However, history shows that even under adverse conditions, people can cooperate. As a prelude to cooperation, people can establish (or reinforce) social ties through communication. Consequently, individuals' cognitive states may synchronize, so that they can depend on like-minded people rather than on a situation beyond their control. Whether this succeeds largely depends on the network that is formed (or used), which should also help them to overcome misunderstandings and to synchronize relatively fast. From a well-known model of social influence it is inferred that network patterns with high algebraic connectivity, featuring multiple independent connections, are optimal for collective action.

    2015-01-01

    The present work deals with a combined test of the so-called Fractional Action Cosmology (FAC) on the example of a specific model obtained by the author earlier. In this model, the effective cosmological term is proportional to the Hubble parameter squared through the so-called kinematic induction. The reason of studying this cosmological model could be explained by its ability to describe two periods of accelerated expansion, that is in agreement with the recent observations and the cosmological inflation paradigm. First of all, we put our model through the theoretical tests that gives a general conception of the influence of the model parameters on its behavior. Then, we obtain some restrictions on the principal parameters of the model, including the fractional index, by means of the observational data. Finally, the cosmography parameters and the observational data compared to the theoretical predictions are presented both analytically and graphically.

    2016-06-01

    We give a pedagogical introduction to the methodology of the Quench Action, which is an effective representation for the calculation of time-dependent expectation values of physical operators following a generic out-of-equilibrium state preparation protocol (for example a quantum quench). The representation, originally introduced in Caux and Essler (2013 Phys. Rev. Lett. 110 257203), is founded on a mixture of exact data for overlaps together with variational reasonings. It is argued to be quite generally valid and thermodynamically exact for arbitrary times after the quench (from short times all the way up to the steady state), and applicable to a wide class of physically relevant observables. Here, we introduce the method and its language, give an overview of some recent results, suggest a roadmap and offer some perspectives on possible future research directions.

    The heights of iterates of the discrete Painleve equations over number fields appear to grow no faster than polynomials while the heights of generic solutions of non-integrable discrete equations grow exponentially. This gives rise to a simple and effective numerical test for the integrability of discrete equations. Numerical evidence and theoretical results are presented. Connections with other tests for integrability and Vojta's dictionary are discussed. (letter to the editor)

  8. Social Inclusion and Integrative Practices

    2014-06-01

    Full Text Available With the passage of time valuable lessons have been learnt about both effective practices for program and system integration and the sizable barriers, including the challenges in sustaining constructive integration. This paper is a reflection on sustainable integrative practices and is grounded in the direct experience of one of the authors, who held the post of the South Australian Social Inclusion Commissioner. We reflect upon the structure and mechanism of the South Australian Social Inclusion Initiative (2002–2011 as well as using a case study of a successful integrative program of the Social Inclusion Initiative, a program in South Australia’s School Retention Action Plan 2004 Making the Connections (South Australian Social Inclusion Board, 2004 that was implemented to improve school retention. The case study draws out salient factors of clear rationale, coordination, collaboration, communication, team work and trust as skills and ingredients to bring about integration in policy and programs. While the integration literature affirms that these ingredients are primary skills for the development of an integrative framework, we also assert that they are not enough for successful and sustained integration. Absent from much of the literature is a discussion about the use of power and the manner in which horizontal integrative work occurs. We take up this theme to draw out some implications for analysis of sustainable integrative practices.

The method employed by the integral equation approach specifically includes the boundary conditions, which confers a valuable advantage. In addition, the integral equation approach leads naturally to the solution of the problem--under suitable conditions--in the form of an infinite series.Geared toward upper-level undergraduate students, this text focuses chiefly upon linear integral equations.

    We present the universal one-loop effective action for all operators of dimension up to six obtained by integrating out massive, non-degenerate multiplets. Our general expression may be applied to loops of heavy fermions or bosons, and has been checked against partial results available in the literature. The broad applicability of this approach simplifies one-loop matching from an ultraviolet model to a lower-energy effective field theory (EFT), a procedure which is now reduced to the evaluation of a combination of matrices in our universal expression, without any loop integrals to evaluate. We illustrate the relationship of our results to the Standard Model (SM) EFT, using as an example the supersymmetric stop and sbottom squark Lagrangian and extracting from our universal expression the Wilson coefficients of dimension-six operators composed of SM fields.

    Too often, credible scientific early warning information of increased disaster risk does not result in humanitarian action. With financial resources tilted heavily towards response after a disaster, disaster managers have limited incentive and ability to process complex scientific data, including uncertainties. These incentives are beginning to change, with the advent of several new forecast-based financing systems that provide funding based on a forecast of an extreme event. Given the changing landscape, here we demonstrate a method to select and use appropriate forecasts for specific humanitarian disaster prevention actions, even in a data-scarce location. This action-based forecasting methodology takes into account the parameters of each action, such as action lifetime, when verifying a forecast. Forecasts are linked with action based on an understanding of (1) the magnitude of previous flooding events and (2) the willingness to act "in vain" for specific actions. This is applied in the context of the Uganda Red Cross Society forecast-based financing pilot project, with forecasts from the Global Flood Awareness System (GloFAS). Using this method, we define the "danger level" of flooding, and we select the probabilistic forecast triggers that are appropriate for specific actions. Results from this methodology can be applied globally across hazards and fed into a financing system that ensures that automatic, pre-funded early action will be triggered by forecasts.

  14. Beyond rational imitation: learning arbitrary means actions from communicative demonstrations.

    Science.gov (United States)

    Király, Ildikó; Csibra, Gergely; Gergely, György

    2013-10-01

    The principle of rationality has been invoked to explain that infants expect agents to perform the most efficient means action to attain a goal. It has also been demonstrated that infants take into account the efficiency of observed actions to achieve a goal outcome when deciding whether to reenact a specific behavior or not. It is puzzling, however, that they also tend to imitate an apparently suboptimal unfamiliar action even when they can bring about the same outcome more efficiently by applying a more rational action alternative available to them. We propose that this apparently paradoxical behavior is explained by infants' interpretation of action demonstrations as communicative manifestations of novel and culturally relevant means actions to be acquired, and we present empirical evidence supporting this proposal. In Experiment 1, we found that 14-month-olds reenacted novel arbitrary means actions only following a communicative demonstration. Experiment 2 showed that infants' inclination to reproduce communicatively manifested novel actions is restricted to behaviors they can construe as goal-directed instrumental acts. The study also provides evidence that infants' reenactment of the demonstrated novel actions reflects epistemic motives rather than purely social motives. We argue that ostensive communication enables infants to represent the teleological structure of novel actions even when the causal relations between means and end are cognitively opaque and apparently violate the efficiency expectation derived from the principle of rationality. This new account of imitative learning of novel means shows how the teleological stance and natural pedagogy--two separate cognitive adaptations to interpret instrumental versus communicative actions--are integrated as a system for learning socially constituted instrumental knowledge in humans.

  15. Integrable systems on semidirect product Lie groups

    2013-01-01

    We study integrable systems on the semidirect product of a Lie group and its Lie algebra as the representation space of the adjoint action. Regarding the tangent bundle of a Lie group as phase space endowed with this semidirect product Lie group structure, we construct a class of symplectic submanifolds equipped with a Dirac bracket on which integrable systems (in the Adler-Kostant-Symes sense) are naturally built through collective dynamics. In doing so, we address other issues as factorization, Poisson-Lie structures and dressing actions. We show that the procedure becomes recursive for some particular Hamilton functions, giving rise to a tower of nested integrable systems.

    Symplectic integrators are widely used for long-term integration of conservative astrophysical problems due to their ability to preserve the constants of motion; however, they cannot in general be applied in the presence of nonconservative interactions. In this Letter, we develop the “slimplectic” integrator, a new type of numerical integrator that shares many of the benefits of traditional symplectic integrators yet is applicable to general nonconservative systems. We utilize a fixed-time-step variational integrator formalism applied to the principle of stationary nonconservative action developed in Galley et al. As a result, the generalized momenta and energy (Noether current) evolutions are well-tracked. We discuss several example systems, including damped harmonic oscillators, Poynting–Robertson drag, and gravitational radiation reaction, by utilizing our new publicly available code to demonstrate the slimplectic integrator algorithm. Slimplectic integrators are well-suited for integrations of systems where nonconservative effects play an important role in the long-term dynamical evolution. As such they are particularly appropriate for cosmological or celestial N-body dynamics problems where nonconservative interactions, e.g., gas interactions or dissipative tides, can play an important role.

  18. Is credit for early action credible early action?

    International Nuclear Information System (INIS)

    Credit for early action as a tool for greenhouse gas emissions reduction is compared with various market instruments as a means of narrowing the gap between projected emissions and those of the Kyoto Protocol. Market instruments work by creating a market price for emissions and use the market to encourage reductions at the lowest price, which is done by placing limits on greenhouse gas emissions and allowing the market to decide where reductions occur, or by imposing a carbon tax or emissions charge. While they can be applied within a sector, they are usually used to encourage reductions throughout the economy or across large sectors. Credit for early action also creates an incentive for emissions reductions throughout the economy or at least across many sectors. Credit for early action tools do not work by either imposing a carbon tax or emissions charge or placing limits on emissions, rather they promise that entities that take action against greenhouse gases prior to the imposition of a carbon tax or emissions limits will receive a credit against future taxes or limits. An overview is provided of the Kyoto Protocol and the rationale for taking early action, and a review is included of the theory and specific proposals for market instruments and credit for early action. A comparative analysis is provided of these approaches by examining their relative efficiency, environmental effectiveness, and impacts on the redistribution of wealth. Credit for early action is viewed as problematic on a number of counts and is seen as an interim strategy for imposition while political support for market instruments develop. The environmental effectiveness of credit for early action is very difficult to predict, and credit for early action programs do not yield the lowest cost emissions reductions. Credit for early action programs will not achieve compliance with the Kyoto Protocol at the lowest cost, and credits for early action will increase the compliance costs for those who

    Full Text Available Smoke can break dormancy and promote seed germination of many plant species. We investigated changes in the gene expression changes after imbibition of light-sensitive Lactuca sativa L. cv. Grand Rapids achenes with dilute smoke water compared to water control samples kept in dark or continuous light. Although no difference was detected in the smoke water vs. water control samples germinated in light, smoke water treatment resulted in the differential display of several expressed sequence tags (ESTs when compared to water control samples kept in dark. The most pronounced fragments isolated correspond to known genes with functions related to cell wall expansion, abscisic acid regulation, regulation of translation, the cell division cycle, carbohydrate metabolism and desiccation tolerance. These data clearly indicate that the smoke water, which stimulates germination of light-sensitive Grand Rapids lettuce seeds in the dark, rapidly affects genes that are essential for cell division, cell wall expansion and mobilization and utilization of nutrients for the resumption of embryo growth. Although the master genes remained unknown, our hope is that the using of maize microarray will reveal the whole molecular background of smoke action.

Education should respect the basic laws of the develop and progress. Curiosity is the engine of achievement and children spontaneously and happily learn only if they get interested, if teacher wake up and stimulate their creativity and individuality. We would like to present classes that are realized as thematic teaching with several subjects involved: chemistry, geography, math, art and biology. Classes were organized for students at age from 10 to 13 years, every month during autumn and winter 2015. Better students identified themselves as teachers and presented peer education .Teachers were monitoring the process of teaching and help to develop links between younger and older students, where older students were educators to younger students. Also one student with special needs was involved in this activities and was supported by other students during the workshops The benefit from this project will be represented with evaluation marks. Evaluation table shows that group of ten students(age 10 to13 years) which are selected in October as children with lack of motivation for learning, got better marks, at the end of January , then they had it in the beginning of the semester.

  4. Numbers in Action

    Science.gov (United States)

    Rugani, Rosa; Sartori, Luisa

    2016-01-01

    Humans show a remarkable tendency to describe and think of numbers as being placed on a mental number line (MNL), with smaller numbers located on the left and larger ones on the right. Faster responses to small numbers are indeed performed on the left side of space, while responses to large numbers are facilitated on the right side of space (spatial-numerical association of response codes, SNARC effect). This phenomenon is considered the experimental demonstration of the MNL and has been extensively replicated throughout a variety of paradigms. Nevertheless, the majority of previous literature has mainly investigated this effect by means of response times and accuracy, whereas studies considering more subtle and automatic measures such as kinematic parameters are rare (e.g., in a reaching-to-grasp movement, the grip aperture is enlarged in responding to larger numbers than in responding to small numbers). In this brief review we suggest that numerical magnitude can also affect the what and how of action execution (i.e., temporal and spatial components of movement). This evidence could have large implications in the strongly debated issue concerning the effect of experience and culture on the orientation of MNL. PMID:27524965

    2006-01-01

    The systematic analysis of acting-out episodes can be used in assessing analytic progress. Variables to be considered are the nature of the wish, the type of defense, and the degree of concreteness (versus symbolization) of the mental processes used in attempting actualization (as distinct from the resort to action). Two acting-out episodes of a borderline patient who acted out as a character trait, both occurring outside the analytic setting, are presented as illustrations. In the first one, occurring relatively early in the analysis, when split-off negative and positive self-images had to be rigidly maintained, ejection of the negative self-image was actualized via the regressive use of a symbolic equation and the mechanism of displacement, obliterating the distinction between an internal feeling and an external thing that here was literally thrown out. The later episode, occurring after the split was healed and within the context of a frustrating heterosexual involvement, contained an acted-out allusion to identification and competition with the mother. As in a dream, via associations, an unconscious wish for oedipal victory was revealed. Whereas in the first episode the goal of ejection was central, with splitting and denial the underlying defenses, it was absent from the second, in which an attempt was made to actualize a repressed infantile wish and made greater use of symbolization. It is concluded that acting-out episodes at different periods of the analysis, when systematically analyzed, can serve in assessing a patient's progress.

  6. Nonclassical Vitamin D Actions

    Armin Zittermann

    2010-03-01

    Full Text Available It is becoming increasingly clear that vitamin D has a broad range of actions in the human body. Besides its well-known effects on calcium/phosphate homeostasis, vitamin D influences muscle function, cardiovascular homeostasis, nervous function, and the immune response. Vitamin D deficiency/insufficiency has been associated with muscle weakness and a high incidence of various chronic diseases such as cardiovascular disease, cancer, multiple sclerosis, and type 1 and 2 diabetes. Most importantly, low vitamin D status has been found to be an independent predictor of all-cause mortality. Several recent randomized controlled trials support the assumption that vitamin D can improve muscle strength, glucose homeostasis, and cardiovascular risk markers. In addition, vitamin D may reduce cancer incidence and elevated blood pressure. Since the prevalence of vitamin D deficiency/insufficiency is high throughout the world, there is a need to improve vitamin D status in the general adult population. However, the currently recommended daily vitamin D intake of 5–15 µg is too low to achieve an adequate vitamin D status in individuals with only modest skin synthesis. Thus, there is a need to recommend a vitamin D intake that is effective for achieving adequate circulating 25-hydroxyvitamin D concentrations (>75 nmol/L.

    Full Text Available IMGIP and ICEOP are minority graduate fellowship programs sponsored by the State of Illinois in order to increase the number of minority faculty and professional staff at Illinois institutions of higher education through graduate fellowships, networking and mentoring support. Nearly 850 fellowships have been awarded since 1986. A performance audit examined immediate (areas of graduate study, ethnicity of awards, intermediate (graduation areas and rates, and long-range results (academic job placement. The primary source for the audit was the database maintained by the programs' administrative office. These data were compared with data sets maintained by the Illinois Board of Higher Education and with national benchmarks (NSF and Ford Foundation Minority Graduate Fellowships.

    2009-01-01

    We apply the laws of human gait vertical ground reaction force and discover the existence of the phenomenon of least action principle in gait. Using a capacitive mat transducer system, we obtain the variations of human gait vertical ground reaction force and establish a structure equation for the resultant of such a force. Defining the deviation of vertical force as an action function, we observe from our gait optimization analysis the least action principle at half of the stride time. We develop an evaluation index of mechanical energy consumption based upon the least action principle in gait. We conclude that these observations can be employed to enhance the accountability of gait evaluation.

The simulations show that non-functional action sequences do indeed increase prediction error, but that context representations, such as abstract goal information, can modulate the error signal considerably. It is also shown......By means of the computational approach the present study investigates the difference between observation of functional behavior (i.e. actions involving necessary integration of subparts) and non-functional behavior (i.e. actions lacking necessary integration of subparts) in terms of prediction...... behavioral study has shown that human subjects segment non-functional behavior in a more fine-grained way than functional behavior. This increase in segmentation rate implies that non-functionality elicits a stronger error signal. To further explore the implications, two computer simulations using simple...

  17. On supersymmetry, boundary actions and brane charges

    Science.gov (United States)

    Di Pietro, Lorenzo; Klinghoffer, Nizan; Shamir, Itamar

    2016-02-01

    Supersymmetry transformations change the Lagrangian [InlineMediaObject not available: see fulltext.] into a total derivative [InlineMediaObject not available: see fulltext.]. On manifolds with boundaries the total derivative term is an obstruction to preserving supersymmetry. Such total derivative terms can be canceled by a boundary action without specifying boundary conditions, but only for a subalgebra of supersymmetry. We study compensating boundary actions for {N}=1 supersymmetry in 4d, and show that they are determined independently of the details of the theory and of the boundary conditions. Two distinct classes of boundary actions exist, which correspond to preserving either a linear combination of supercharges of opposite chirality (called A-type) or supercharges of opposite chirality independently (B-type). The first option preserves a subalgebra isomorphic to {N}=1 in 3d, while the second preserves only a 2d subgroup of the Lorentz symmetry and a subalgebra isomorphic to {N}=(0,2) in 2d. These subalgebras are in one to one correspondence with half-BPS objects: the A-type corresponds to domain walls while the B-type corresponds to strings. We show that integrating the full current algebra and taking into account boundary contributions leads to an energy-momentum tensor which contains the boundary terms. The boundary terms come from the domain wall and string currents in the two respective cases.

  18. Action co-representation and social exclusion.

    Science.gov (United States)

    Costantini, Marcello; Ferri, Francesca

    2013-05-01

    Humans are thought to be able to form shared representations, considered a keystone of social cognition. However, whether and to what extent such representations are social in nature is still open for debate. In the present study, we address the question of whether action co-representation can be modulated by social attitudes, such as judgments about one's own social status. Two groups of participants performed an Interactive Simon task after the experimental induction of a feeling of social inclusion or exclusion (ostracism) by means of a virtual ball tossing game. Results showed a compatibility effect in included, but not in excluded participants. This indicates that judgments about one's own social status modulate action co-representation. We suggest that this modulation may occur by way of a redirection of one's attentional focus away from others when one experiences social exclusion. This is a far-reaching issue given the increasing need for integration in modern society. Indeed, if integration fails, modern society fails also. PMID:23543105

  19. Complex Action Support from Coincidences of Couplings

    CERN Document Server

    Nielsen, Holger Bech

    2011-01-01

    The model of Ninomiya and myself of complex action in a functional integral formulation interpreted by means of path integrals extending over all times, both past and future, is reviewed. A few numerical relations between coupling constants and masses are taken as supporting evidences. The new one such supporting ev- idence among the mentioned "coincidences" is that our model is able to explain (suggestively) that a) the Higgs field expectation value is very small ("scale problem") compared to say some fundamental scale that might be the Planck scale, b) This Higgs VEV scale need not be just zero, but rather is predicted to be so that the running top-quark Yukawa coupling just is about unity at this scale. In this way it is easily becoming an "exponentially" small scale. Instead of the top-Yukawa we should rather here say the highest flavour Yukawa coupling. These predictions are only achieved by allowing the principle of minimization of the imaginary part of the action SI(history) to to a certain extent adju...

  20. European Integration and Globalization

    Directory of Open Access Journals (Sweden)

    Diana Bobica

    2010-06-01

    Full Text Available According to many, the term globalization is able to explain any phenomenon whatsoever, be it positive or negative, that takes place within the global social system. It seems like a sort of magical formula, which is to be found in the speeches of all sorts of people, be they economists, politicians, businessmen or sociologists. However this magical formula of globalization has its limitations, since it encompasses a certain amount of quibbling, beyond which not many can pass. In the context of globalization there appears the question on its role in the process of European integration. Is European integration a part of this global process or, quite on the contrary, does it present certain distinctive features, as it moulds itself differently from the globalization phenomenon? A clear-cut answer seems difficult because of the various aspects involved. Not only the general phenomenon of globalization, but also the economic integration on European level is based on the liberalization of markets and on the opening of national economies towards the exterior,having as direct consequence the intensification of trade exchanges. If from a global point of view one may talk of a market fundamentalism in that the market principles know no boundary, European integration on the other hand implies not only market economy, but also a guided and monitored action of Member Statesaccording to the needs of the whole entity, also taking into consideration - as far as possible – all aspects and consequences on social level.

  1. Constituting children's bodily integrity.

    Science.gov (United States)

    Hill, B Jessie

    2015-04-01

    Children have a constitutional right to bodily integrity. Courts do not hesitate to vindicate that right when children are abused by state actors. Moreover, in at least some cases, a child's right to bodily integrity applies within the family, giving the child the right to avoid unwanted physical intrusions regardless of the parents' wishes. Nonetheless, the scope of this right vis-à-vis the parents is unclear; the extent to which it applies beyond the narrow context of abortion and contraception has been almost entirely unexplored and untheorized. This Article is the first in the legal literature to analyze the constitutional right of minors to bodily integrity within the family by spanning traditionally disparate doctrinal categories such as abortion rights; corporal punishment; medical decisionmaking; and nontherapeutic physical interventions such as tattooing, piercing, and circumcision. However, the constitutional right of minors to bodily integrity raises complex philosophical questions concerning the proper relationship between family and state, as well as difficult doctrinal and theoretical issues concerning the ever-murky idea of state action. This Article canvasses those issues with the ultimate goal of delineating a constitutional right of bodily security and autonomy for children. PMID:26016017

  2. Plebanski-like action for general relativity and anti-self-dual gravity

    Science.gov (United States)

    Celada, Mariano; González, Diego; Montesinos, Merced

    2016-05-01

    We present a new B F -type action for complex general relativity with or without a cosmological constant resembling Plebanski's action, which depends on an SO (3 ,C ) connection, a set of 2-forms, a symmetric matrix, and a 4-form. However, it differs from the Plebanski formulation in the way that the symmetric matrix enters into the action. The advantage of this fact is twofold. First, as compared to Plebanski's action, the symmetric matrix can now be integrated out, which leads to a pure B F -type action principle for general relativity; the canonical analysis of the new action then shows that it has the same phase space of the Ashtekar formalism up to a canonical transformation induced by a topological term. Second, a particular choice of the parameters involved in the formulation produces a B F -type action principle describing conformally anti-self-dual gravity. Therefore, the new action unifies both general relativity and anti-self-dual gravity.

    ,Z-muconaldehyde forms cyclic products containing a pyrrole residue linked to purine. Increased HbCO concentrations reduce the O2-carrying capacity of the blood, and the changed shape of the O2-Hb dissociation curve parallels disturbance in O2 unloading. CN- acts on electron transport and paralyses respiration. In telodrin poisoning, preconvulsive glutamine formation abstracts tricarboxylic acid intermediates incommensurately with normal cerebral respiration. Antigen-antibody complexing depletes the antibody titre, available against infection. At high doses of Cd, Cd-thionein filtered through the kidneys is reabsorbed and tubular lesions produced. Some organophosphate insecticides promote irreversible acetylcholinesterase phosphorylation and blockade nerve function, and others react with neurotoxic esterase to cause delayed neuropathy. The evidence for Paraquat pulmonary poisoning suggests a radical mechanism involving three interrelated cyclic reaction stages. The action of N- and O8 (O substituent in 6-position of the purine) demethylases explains deletion mechanisms for DNA-alkyl adducts. DNA-directed synthesis in the presence of ultimate carcinogens provides for an estimation of misincorporations, which implicate the same transversions as those found by direct mutagenicity testing. Chemical carcinogens recognize tissue-sensitive cells and modify their heritable genetic complement. Oncoproteins encoded by activated oncogenes signal the transformation of normal cells into cancer cells. The importance of the H-ras oncogene and p53 tumour-suppressor gene is stressed. Antidotal action is analysed; for example, parenteral glutamine administration to telodrin-intoxicated rats restores the depleted cerebral glutamate level and prevents seizures. Glutamate acts as anticonvulsant in petit mal epilepsy. In general, therefore, the reaction of the toxicant-related substance with the relevant target-tissue macromolecule accounts for the biochemical/biological events at a cellular level a PMID

  7. Leadership solves collective action problems in small-scale societies.

    Glowacki, Luke; von Rueden, Chris

    2015-12-01

    Observation of leadership in small-scale societies offers unique insights into the evolution of human collective action and the origins of sociopolitical complexity. Using behavioural data from the Tsimane forager-horticulturalists of Bolivia and Nyangatom nomadic pastoralists of Ethiopia, we evaluate the traits of leaders and the contexts in which leadership becomes more institutional. We find that leaders tend to have more capital, in the form of age-related knowledge, body size or social connections. These attributes can reduce the costs leaders incur and increase the efficacy of leadership. Leadership becomes more institutional in domains of collective action, such as resolution of intragroup conflict, where collective action failure threatens group integrity. Together these data support the hypothesis that leadership is an important means by which collective action problems are overcome in small-scale societies.

    Highlights: • The concept of ‘space for action’ offers an important new lens on EA practice. • Focuses on the relation between practitioner's understanding and their actions • Environmental assessment practice is decisively shaped by practitioners. • Practitioners may underestimate their potential to make a difference. • Contributes to understanding change in the environmental assessment field. This article contributes to understanding of how change occurs in the field of environmental assessment (EA). It argues that the integration of new issues in EA, such as human health, is significantly influenced by how practitioners' understandings shape their actions, and by what happens when those, possibly different, interpretations of appropriate action are acted out. The concept of space for action is developed as a means of investigating this relation between understanding and action. Frame theory is also used, to develop a sharper focus on how ‘potential spaces for action’ are created, what these imply for (individuals') preferred choices and actions in certain situations, and what happens in practice when these are acted out and ‘actual spaces for action’ are created. This novel approach is then applied in a Swedish case study of transport planning. The analysis reveals the important work done by practitioners, revealing just how EA practice is decisively shaped by practitioners. Analysis of practice using the lens of spaces for action offers an important new perspective in understanding how the field adapts to new challenges.

  3. Evolutionary dynamics of collective action in spatially structured populations.

    Science.gov (United States)

    Peña, Jorge; Nöldeke, Georg; Lehmann, Laurent

    2015-10-01

    Many models proposed to study the evolution of collective action rely on a formalism that represents social interactions as n-player games between individuals adopting discrete actions such as cooperate and defect. Despite the importance of spatial structure in biological collective action, the analysis of n-player games games in spatially structured populations has so far proved elusive. We address this problem by considering mixed strategies and by integrating discrete-action n-player games into the direct fitness approach of social evolution theory. This allows to conveniently identify convergence stable strategies and to capture the effect of population structure by a single structure coefficient, namely, the pairwise (scaled) relatedness among interacting individuals. As an application, we use our mathematical framework to investigate collective action problems associated with the provision of three different kinds of collective goods, paradigmatic of a vast array of helping traits in nature: "public goods" (both providers and shirkers can use the good, e.g., alarm calls), "club goods" (only providers can use the good, e.g., participation in collective hunting), and "charity goods" (only shirkers can use the good, e.g., altruistic sacrifice). We show that relatedness promotes the evolution of collective action in different ways depending on the kind of collective good and its economies of scale. Our findings highlight the importance of explicitly accounting for relatedness, the kind of collective good, and the economies of scale in theoretical and empirical studies of the evolution of collective action.

    The ability to act jointly with another person is a fundamental requirement for participation in social life. The current study examines the development of action planning in a joint action context. In 4 experiments, 3-, 5-, and 7-year-old children as well as a group of adults (n = 196) interacted with another person to operate a novel apparatus. Their task was to hand the experimenter a tool with which she could activate 1 of 2 different effects on the apparatus. The elicitation of each effect required participants to grasp and insert the tool in a particular orientation. We assessed whether participants planned their grasping and reaching action in such a way that it enabled the partner to efficiently handle the tool, that is, anticipating the final end state of the joint activity. We found that 3-year-old children did not adjust their behavior to accommodate the other's action and that they did not increase their performance over multiple trials. Five- and 7-year-old children initially showed a tendency to plan their action in an egocentric manner (i.e., showed a form of egocentrism), but improved their joint action performance over time. Adult participants demonstrated joint action planning from the beginning. Interestingly, 3- and 5-year-old children were able to plan their grasp efficiently when acting alone on the apparatus. Yet, having first-hand experience with the task before acting with a partner did not facilitate performance in the joint action task for younger children. Overall, the study informs current approaches on the psychological basis and ontogenetic origins of joint action in childhood. (PsycINFO Database Record PMID:27337512

    In a project funded by the Swedish Civil Contingencies Agency, the effort and work to reduce different kinds of accidents are being evaluated. The project wants to illuminate the links between actions and outcome, so we can learn from today's performance and in the future select more effective measures and overall deal with accidents more efficiently. The project ESS covers the field of frequent accidents such as sliding accidents at home, in house fires and less common accidents such as chemical and land fill accidents up to even more rare accidents such as natural accidents and hazards. In the ESS project SGI (Swedish geotechnical institute) will evaluate the work and effort concerning various natural hazards limited to landslides, erosion and flooding. The aim is to investigate how municipalities handle, especially prevention, of such natural disasters today. The project includes several aspects such as: • which are the driving forces for risk analysis in a municipality • do one use risk mapping (and what type) in municipal risk analysis • which aspects are most important when selecting preventive measures • in which way do one learn from past accidents • and from previous accidents elsewhere, by for example use existing databases • etc There are many aspects that play a role in a well-functioning safety promotion work. The overall goal is to examine present work and activities, highlight what is well functioning and identify weak points. The aim is to find out where more resources are needed and give suggestions for a more efficient security work. This includes identification of the most efficient "tools" in use or needed. Such tools can be education, directives, funding, more easily available maps and information regarding previous accidents and preventive measures etc. The project will result in recommendations for more effective ways to deal with landslides, erosion and flooding. Since different kinds of problems can occur depending on level of

In practice, the committing of an illegal act may cause prejudice, being described as a civil offense, but at the same time may create a report of criminal law, attracting the criminal liability, in which case it is called offense. This is how we find in the jurisprudence, both civil action and criminal action, so that, in this study we try to present some singularities of these two types of actions, and of the relation between them.

    2006-12-01

    Full Text Available I have heard it said, as many of us have, that evidence based library and information practice is an area dominated and led by librarians in the health sciences. It is a logical leap to say that medical librarians may be more familiar with the evidence based model of practice because of their need to be familiar, on some level, with evidence based medicine. The idea of making a decision based on the appropriate evidence is as familiar to a medical librarianas is how to effectively search PubMed. How pervasive is the influence of the medical profession on this area? Being a librarian looking for quick information, I turned to Google. The results on the first two pages from a Google search for evidence based practice are 100% health/medicine related. Being a good librarian, I refined my search to see how the results would differ, and I added the term library to the search. This time there were 75% health/medicine results and 5% representing evidence based library and information practice (eblip. Note that a high percentage of the health/medicine hits were library webpages on evidence based medicine. Being an obsessive‐compulsive librarian, I changed my search strategy again by replacing library with librarianship. This time there were 30% health/medicine results and 65% eblip. A final search for evidence based information had this journal as the top hit. Being a busy librarian with a lot of work to do, I stopped right there. OK, so the terminology appears to point strongly in one direction and weighs heavily on the health sciences penetration. Let’s leave terminology aside for a moment and look at action. Since Evidence Based Library and Information Practice is the first journal on this topic, the list of contributors and their backgrounds should give an indication on whether or not there is a concentration of medical librarians. Approximately two thirds of the articles that we have published are non‐health/medicine related. Only 29% of our

But this would be possible only if they have been fully integrated in the host countries, the integration policies being a task of the national governments. The European Union may still offer support and stimulation through financing, policies coordination and good practices exchange facilitation. The new measures should encourage local level actions, including cooperation between local authorities, employers, migrants’ organizations, service providers and local population. Within the EU, there live 20.1 million immigrants (approximately 4% of the entire population coming from outside European area. An important element of the common EU policy on immigration is the one regarding the development of a policy on immigrants’ integration, which should provide a fair treatment within the member states, and guarantee rights and obligations comparable with the ones of the Union citizens.

  16. The Integrated Hazard Analysis Integrator

    Morris, A. Terry; Massie, Michael J.

    2009-01-01

    Hazard analysis addresses hazards that arise in the design, development, manufacturing, construction, facilities, transportation, operations and disposal activities associated with hardware, software, maintenance, operations and environments. An integrated hazard is an event or condition that is caused by or controlled by multiple systems, elements, or subsystems. Integrated hazard analysis (IHA) is especially daunting and ambitious for large, complex systems such as NASA s Constellation program which incorporates program, systems and element components that impact others (International Space Station, public, International Partners, etc.). An appropriate IHA should identify all hazards, causes, controls and verifications used to mitigate the risk of catastrophic loss of crew, vehicle and/or mission. Unfortunately, in the current age of increased technology dependence, there is the tendency to sometimes overlook the necessary and sufficient qualifications of the integrator, that is, the person/team that identifies the parts, analyzes the architectural structure, aligns the analysis with the program plan and then communicates/coordinates with large and small components, each contributing necessary hardware, software and/or information to prevent catastrophic loss. As viewed from both Challenger and Columbia accidents, lack of appropriate communication, management errors and lack of resources dedicated to safety were cited as major contributors to these fatalities. From the accident reports, it would appear that the organizational impact of managers, integrators and safety personnel contributes more significantly to mission success and mission failure than purely technological components. If this is so, then organizations who sincerely desire mission success must put as much effort in selecting managers and integrators as they do when designing the hardware, writing the software code and analyzing competitive proposals. This paper will discuss the necessary and

  19. Action representation: crosstalk between semantics and pragmatics.

    Science.gov (United States)

    Prinz, Wolfgang

    2014-03-01

    Marc Jeannerod pioneered a representational approach to movement and action. In his approach, motor representations provide both, declarative knowledge about action and procedural knowledge for action (action semantics and action pragmatics, respectively). Recent evidence from language comprehension and action simulation supports the claim that action pragmatics and action semantics draw on common representational resources, thus challenging the traditional divide between declarative and procedural action knowledge. To account for these observations, three kinds of theoretical frameworks are discussed: (i) semantics is grounded in pragmatics, (ii) pragmatics is anchored in semantics, and (iii) pragmatics is part and parcel of semantics.

  2. Tactile perception during action observation.

    Vastano, Roberta; Inuggi, Alberto; Vargas, Claudia D; Baud-Bovy, Gabriel; Jacono, Marco; Pozzo, Thierry

    2016-09-01

    It has been suggested that tactile perception becomes less acute during movement to optimize motor control and to prevent an overload of afferent information generated during action. This empirical phenomenon, known as "tactile gating effect," has been associated with mechanisms of sensory feedback prediction. However, less attention has been given to the tactile attenuation effect during the observation of an action. The aim of this study was to investigate whether and how the observation of a goal-directed action influences tactile perception as during overt action. In a first experiment, we recorded vocal reaction times (RTs) of participants to tactile stimulations during the observation of a reach-to-grasp action. The stimulations were delivered on different body parts that could be either congruent or incongruent with the observed effector (the right hand and the right leg, respectively). The tactile stimulation was contrasted with a no body-related stimulation (an auditory beep). We found increased RTs for tactile congruent stimuli compared to both tactile incongruent and auditory stimuli. This effect was reported only during the observation of the reaching phase, whereas RTs were not modulated during the grasping phase. A tactile two-alternative forced-choice (2AFC) discrimination task was then conducted in order to quantify the changes in tactile sensitivity during the observation of the same goal-directed actions. In agreement with the first experiment, the tactile perceived intensity was reduced only during the reaching phase. These results suggest that tactile processing during action observation relies on a process similar to that occurring during action execution. PMID:27161552

    Robots are increasingly expected to perform tasks in complex environments. To this end, engineers provide them with processing architectures that are based on models of human information processing. In contrast to traditional models, where information processing is typically set up in stages (i.e., from perception to cognition to action), it is increasingly acknowledged by psychologists and robot engineers that perception and action are parts of an interactive and integrated process. In this paper, we present HiTEC, a novel computational (cognitive) model that allows for direct interaction between perception and action as well as for cognitive control, demonstrated by task-related attentional influences. Simulation results show that key behavioral studies can be readily replicated. Three processing aspects of HiTEC are stressed for their importance for cognitive robotics: (1) ideomotor learning of action control, (2) the influence of task context and attention on perception, action planning, and learning, and (3) the interaction between perception and action planning. Implications for the design of cognitive robotics are discussed.

  13. A review of action estimation methods for galactic dynamics

    Sanders, Jason L.; Binney, James

    We review the available methods for estimating actions, angles and frequencies of orbits in both axisymmetric and triaxial potentials. The methods are separated into two classes. Unless an orbit has been trapped by a resonance, convergent, or iterative, methods are able to recover the actions to arbitrarily high accuracy given sufficient computing time. Faster non-convergent methods rely on the potential being sufficiently close to a separable potential, and the accuracy of the action estimate cannot be improved through further computation. We critically compare the accuracy of the methods and the required computation time for a range of orbits in an axisymmetric multicomponent Galactic potential. We introduce a new method for estimating actions that builds on the adiabatic approximation of Schönrich & Binney and discuss the accuracy required for the actions, angles and frequencies using suitable distribution functions for the thin and thick discs, the stellar halo and a star stream. We conclude that for studies of the disc and smooth halo component of the Milky Way, the most suitable compromise between speed and accuracy is the Stäckel Fudge, whilst when studying streams the non-convergent methods do not offer sufficient accuracy and the most suitable method is computing the actions from an orbit integration via a generating function.

  15. Linking knowledge to action in collaborative conservation.

    2011-12-01

    Authors have documented a "research-implementation gap" in conservation. Research intended to inform conservation practice often does not, and practice often is not informed by the best science. We used the literature on policy learning (i.e., literature attributing policy change to learning) to structure a study of how practice is informed by science in collaborative conservation. We studied implementation by U.S. states of state wildlife action plans. On the basis of 60 interviews with government and nongovernmental organization representatives, we identified 144 implementation initiatives for State Wildlife Action Plans that were collaborative. We conducted case studies of 6 of these initiatives, which included interviews of key individuals and analysis of written documents. We coded interview transcripts and written documents to identify factors that influence availability and use of scientific information. We integrated these factors into a model of collaborative conservation. Although tangible factors such as funding and labor directly affected the availability of scientific information, practitioners' ability and willingness to use the information depended on less tangible factors such as the quality of interpersonal relationships and dialogue. Our work demonstrates empirically that relationships and dialogue led to: (1) the sharing of resources, such as funding and labor, that were needed to carry out research and produce information and (2) agreement among researchers and practitioners on conservation objectives, which was necessary for that new information to inform action. Our findings can be understood in the context of broader concepts articulated in the policy-learning literature, which establishes that social learning (improving relationships and dialogue) provides the foundation for conceptual learning (setting objectives) and technical learning (determining how to achieve these objectives).

  16. Granger causality mapping during joint actions reveals evidence for forward models that could overcome sensory-motor delays.

    Directory of Open Access Journals (Sweden)

    Idil Kokal

    Full Text Available Studies investigating joint actions have suggested a central role for the putative mirror neuron system (pMNS because of the close link between perception and action provided by these brain regions [1], [2], [3]. In contrast, our previous functional magnetic resonance imaging (fMRI experiment demonstrated that the BOLD response of the pMNS does not suggest that it directly integrates observed and executed actions during joint actions [4]. To test whether the pMNS might contribute indirectly to the integration process by sending information to brain areas responsible for this integration (integration network, here we used Granger causality mapping (GCM [5]. We explored the directional information flow between the anterior sites of the pMNS and previously identified integrative brain regions. We found that the left BA44 sent more information than it received to both the integration network (left thalamus, right middle occipital gyrus and cerebellum and more posterior nodes of the pMNS (BA2. Thus, during joint actions, two anatomically separate networks therefore seem effectively connected and the information flow is predominantly from anterior to posterior areas of the brain. These findings suggest that the pMNS is involved indirectly in joint actions by transforming observed and executed actions into a common code and is part of a generative model that could predict the future somatosensory and visual consequences of observed and executed actions in order to overcome otherwise inevitable neural delays.

  1. Integrated Usability Testing

    2015-11-01

    Full Text Available It is essential to regularly test the usability of a learning management system, in order to ensure a fast adoption by new users and rapidly shift the focus from the platform to the content and the learning experience. Quantitative testing yields the most reliable results due to the large number of data points acquired, but lacks the in-depth analysis of the qualitative research from a controlled testing setup. We are proposing in this paper an integrated usability testing tool, which can replace a certain type of laboratory testing, where the users’ actions on the real platform are measured and analyzed. We conducted tests with the tool and compared the results with a small scale laboratory test using the same scenarios. The results seem to confirm the proposed tool as a viable alternative to the laboratory test.

    In Romania, the free access to the law is considered a fundamental human right, enriched by the Constitution itself. In practice, the committing of an illegal act may cause prejudice, being described as a civil offense, but at the same time may create a report of criminal law, attracting the criminal liability, in which case it is called offense. This is how we find in the jurisprudence, both civil action and criminal action, so that, in this study we try to present some singularities of thes...

  9. Environmental actors and European integration: Attitudes towards further integration

    Energy Technology Data Exchange (ETDEWEB)

    Dahl, A.

    1994-12-31

    This report asks to what extent environmental actors in the EU are positively or negatively inclined to further integration of environmental policy in the EU, and why. The main objective in the EU`s fifth environmental action programme is to integrate environmental concerns into other policy areas. In this study the concept of integration is used to describe various forms of cooperation between states, from independent nation states (inter-governmentalism) at one end of the scale to a supranational authority at the other. What kind of EU cooperation do environmental actors want? Do they believe that further integration of environmental policy in the EU will promote environmental interests and facilitate the integration of environmental concern into other policy areas? Or do they believe that further integration of environmental policy in the EU will reduce the possibilities of developing an ambitious environmental policy in Europe? The empirical material for the study consists of interviews with representatives of political parties and environmental organizations at both the national and the international level. The study concentrates on four arguments called (1) The ``transboundary`` argument, referring to the transboundary character of environmental problems, (2) The single market argument, focusing on the internal market and use of economic instruments in EU environmental policy, (3) The institutional argument, referring to the effectiveness of EU institutions in solving environmental problems and (4) The political influence argument, which focuses on political influence of environmental actors in the development of EU environmental policy. 29 refs., 8 tabs.

    A new perspective on cognition views cortical cell assemblies linking together knowledge about actions and perceptions not only as the vehicles of integrated action and perception processing but, furthermore, as a brain basis for a wide range of higher cortical functions, including attention, meaning and concepts, sequences, goals and intentions, and even communicative social interaction. This article explains mechanisms relevant to mechanistic action perception theory, points to concrete neuronal circuits in brains along with artificial neuronal network simulations, and summarizes recent brain imaging and other experimental data documenting the role of action perception circuits in cognition, language and communication.

  11. Efficient computation of optimal actions.

    Science.gov (United States)

    Todorov, Emanuel

    2009-07-14

    Optimal choice of actions is a fundamental problem relevant to fields as diverse as neuroscience, psychology, economics, computer science, and control engineering. Despite this broad relevance the abstract setting is similar: we have an agent choosing actions over time, an uncertain dynamical system whose state is affected by those actions, and a performance criterion that the agent seeks to optimize. Solving problems of this kind remains hard, in part, because of overly generic formulations. Here, we propose a more structured formulation that greatly simplifies the construction of optimal control laws in both discrete and continuous domains. An exhaustive search over actions is avoided and the problem becomes linear. This yields algorithms that outperform Dynamic Programming and Reinforcement Learning, and thereby solve traditional problems more efficiently. Our framework also enables computations that were not possible before: composing optimal control laws by mixing primitives, applying deterministic methods to stochastic systems, quantifying the benefits of error tolerance, and inferring goals from behavioral data via convex optimization. Development of a general class of easily solvable problems tends to accelerate progress--as linear systems theory has done, for example. Our framework may have similar impact in fields where optimal choice of actions is relevant.
