    2016-01-01

    As French overseas territories have also had a role of leader in the development of renewable energies, and as the French law on energy transition states that energy autonomy is an objective by 2030 for these territories, with 50 per cent of renewable energies by 2020, this publication proposes an overview of the situation in these territories which still strongly depend on imported energies, notably for transports. The publication outlines the specificities of these islands with respect to the metropolitan territory in terms of electric power system: small territories, high production costs, strong consumption increase. It describes how the new energy policy plans evolutions to reach this autonomy: development of renewable energies and of smart grids, development of vehicles fuelled with electricity, biofuels or hydrogen, management of energy consumption in housing and through the use of renewable energies

    The energy question is central to control the climatic change and avoid the wars resulting from the foreign resources dependence. But how act for a real energy autonomy? The author explains many ideas and reveals the real stakes of the question. It is time to change now, before the fossil fuels dry up and the nuclear cannot hide its dangerous and expensive face. In this framework, a policy in favor of the energy auto-sufficiency is an action in favor of the peace. (A.L.B.)

    Lapides, M.E.; Schonberg, R.

    1985-01-01

    MINAC, a portable, high energy radiographic source (1) was recognized as a desired inspection device for nuclear generation plants during EPRI-sponsored studies of the late 1970s and rapidly transitioned from proof-of-principle (1978-1980) to field-proven hardware (1981-present date). The equipment has completed its second generation of configuration development (SHRINKAC), that has recently been used in the field for detection of pipe cracks. Important auxiliaries for image data processing and real-time, thick section radiography have been demonstrated in both laboratory and field situations. Finally, a 6 MeV accelerator alternate is in bench test. These significant developments have, and are expected to continue to upgrade the utility of radiographic inspection in power plant practice. This paper describes the development and experience with this modular system during the last three years

  5. Autonomy-oriented mechanisms for efficient energy distribution

    2010-09-15

    Due to the uneven geographical availability of energy resources, it is essential for the energy suppliers and consumers in different countries/regions to most efficiently, economically, as well as reliably distribute energy resources. In this paper, starting from a specific energy distribution problem, we present a decentralized behavior-based paradigm that draws on the methodology of autonomy-oriented computing. The goal is twofold: (i) to characterize the underlying mechanism of the energy distribution systems, (ii) to provide scalable solutions for efficient energy distribution. We conjecture that efficient energy trading markets can emerge from appropriate behavior-based mechanisms, which can autonomously improve energy distribution efficiency.

    The software portability problem is examined from the viewpoint of experience gained in the operation of a software exchange and information center. First, the factors contributing to the program interchange to date are identified, then major problem areas remaining are noted. The import of the development of programing language and documentation standards is noted, and the program packaging procedures and dissemination practices employed by the Center to facilitate successful software transport are described. Organization, or installation, dependencies of the computing environment, often hidden from the program author, and data interchange complexities are seen as today's primary issues, with dedicated processors and network communications offering an alternative solution

    2012-01-01

    In this study, the energy generation of a set of photovoltaic panels is compared with the energy load of a building in order to analyse its autonomy in the sahelian environment when taking into account, the orientation, the insulation and the energy transfer optimisation of its windows. The Type 56 TRNSYS multizone building model is utilized for the energy load simulation and the Type 94 model of the same code enables the coupling of photovoltaic (PV) panels with the building. Without insulation, the PV energy generation represents 73.52 and 111.79% of the building electric energy load, respectively for poly-crystalline and mono-crystalline panels. For the same PV characteristics and when we insulate the roof and the floor, the energy generation increases to represent successively 121.09 and 184.13%. In the meantime, for building without insulation and with insulate the roof, the floor and 2 cm insulated walls, the energy consumption ratios decrease respectively from 201.13 to 105.20 kWh/m 2 /year. The investigations finally show that it is even possible to generate excess energy (positive energy building) and reduce the number and incident surface area of the PV panels if we conjugate the previous model with building passive architectural design mode (orientation, solar protection ...).

    Guru, S.V.; Squillante, M.R.

    1996-01-01

    To satisfy the needs of high energy gamma ray imagers for industrial nuclear imaging applications, three high energy gamma cameras are presented. The RMD-Pinhole camera uses a lead pinhole collimator and a segmented BGO detector viewed by a 3 in. square position sensitive photomultiplier tube (PSPMT). This pinhole gamma camera displayed an energy resolution of 25.0% FWHM at the center of the camera at 662 keV and an angular resolution of 6.2 FWHM at 412 keV. The fixed multiple hole collimated camera (FMCC), used a multiple hole collimator and a continuous slab of NaI(Tl) detector viewed by the same PSPMT. The FMCC displayed an energy resolution of 12.4% FWHM at 662 keV at the center of the camera and an angular resolution of 6.0 FWHM at 412 keV. The rotating multiple hole collimated camera (RMCC) used a 180 antisymmetric rotation modulation collimator and CsI(Tl) detectors coupled to PIN silicon photodiodes. The RMCC displayed an energy resolution of 7.1% FWHM at 662 keV and an angular resolution of 4.0 FWHM at 810 keV. The performance of these imagers is discussed in this paper. (orig.)

  12. Translating EU renewable energy policy for insular energy systems: Reunion Island's quest for energy autonomy

    2017-12-01

    Full Text Available Recognition of the negative impacts of climate change has led to agreement on the need to decarbonise energy systems through the employment of renewable energy. With many national and transnational policies in place, the options available to insular energy systems (IES differ from those of interconnected areas due to fragility in their production and distribution networks. Based on the concepts of policy mobility and translation, this study examines the interplay of EU renewable energy policy and insular governance processes aimed at achieving energy autonomy through renewable energy development. Reunion Island, a French Overseas Department and Region, is used as a case study to examine local energy governance processes, aspects that shape regional translation of national and EU policy, and the potential effects that create structures and pathways of energy transition. The study shows that Reunion Island’s regional Energy Governance Committee has significant application potential as a governance tool in other IES and small islands within the EU, but that renewable energy development is restricted due to national policy measures and path dependent governance structural constraints.

  13. Energy management and energy autonomy of French farms: status and perspectives of action for public authorities

    International Nuclear Information System (INIS)

    2005-01-01

    This report aims at giving the present state of knowledge about possible energy savings and renewable energy production in farms, and at proposing a hierarchy of actions and measures for a better energy management and energy autonomy in French farms. As far as knowledge is concerned, the authors discuss an assessment of agriculture energy consumption in France, analyse energy costs in farms, discuss the assessment of the global energy consumption by farms, and propose a first estimate of possible energy savings. Actions leading to energy savings or renewable energy production concern various aspects: the production system, agricultural techniques, crops, use of pure vegetal oil, biogas, solar heater, solar drying, buildings, greenhouses, biomass boilers, vegetal oil cogeneration, photovoltaic energy, wind energy. Key actions are identified which concern nitrogen management, wood energy, biogas, energy management, use of cereals for heating, and so on

    Scheer, H.

    2005-07-01

    The petroleum resources are diminishing; resource conflicts invoke the new wars of our century. With increasing energy demand the world races to its existential crisis. The renaissance of nuclear energy is therefore strongly promoted and energy industry is trying by all means to keep their predominance. It is gaming with fire, since only a holistic change over to the use of renewable energy sources can secure global energy demand. Why is rethinking so difficult and what strategies and technologies can help? Hermann Scheer descibes in his new book the manifold mental barriers, the power of traditional energy-thinking, but he also shows, how the change to renewables can be done and made irreversible. The archimedic point is energy autonomy - a manifold feasible, technological, and economical concept. Energy autonomy can only be achieved with renewables and can be used at once and anywhere: decentralized, individually, with immediate noticable consequences. The new policy for renewables, developed by Scheer, frees the energy discussions from its prison fo specialized energy thinking. A ideational and practical guideline for the overdue energy change.

    Climate change and the depletion of fossil fuels have forced the developed world to look for clean energy alternatives. Solar cooking is developing in Asian and African countries blessed with ample sun, but is still at an early stage. A portable autoclave was developed in India using this technology. The Prince-40 Concentrator provided adequate capacity to autoclave culture media and treat biomedical waste in a small laboratory set-up, and could save electricity worth Rs. 15,000 (188.10 GBP)/year or LPG worth Rs. 37,500 (470.25 GBP)/year. This technology would be of immense use in health centres in rural areas with frequent power cuts or no power supply. Copyright © 2012 The Healthcare Infection Society. Published by Elsevier Ltd.

    Energy harvesting has become an increasingly important topic thanks to the advantages in renewability and environmental friendliness. In this paper, a comprehensive study on contemporary portable wind energy harvesters has been conducted. The electrical power generation methods of portable wind energy harvesters are surveyed in three major groups, piezoelectric-, electromagnetic-, and electrostatic-based generators. The paper also takes another view of this area by gauging the required mechanisms for trapping wind flow from ambient environment. In this regard, rotational and aeroelastic mechanisms are analyzed for the portable wind energy harvesting devices. The comparison between both mechanisms shows that the aeroelastic mechanism has promising potential in producing an energy harvester in smaller scale although how to maintain the resonator perpendicular to wind flow for collecting the maximum vibration is still a major challenge to overcome for this mechanism. Furthermore, this paper categorizes the previously published portable wind energy harvesters to macro and micro scales in terms of their physical dimensions. The power management systems are also surveyed to explore the possibility of improving energy conversion efficiency. Finally some insights and research trends are pointed out based on an overall analysis of the previously published works along the historical timeline.

    As the recent law on energy transition defined a legal framework which allowed the action of local authorities in the field of energy, and resulted in the creation of local or territorial energy utilities by these authorities or other actors, this report proposes a presentation of examples of territorial energy utilities or operators. These examples are chosen in different French towns, district or regions (Vienne, Montpellier, Lannion, Pays de Vilaine, Lot, Ile-de-France, Rhone-Alpes) but also in Germany and Austria. Before presenting these experiments, the authors describe and discuss the French legal framework of territorial energy transition. They describe the territorial energy operator as a factor of emergence of an energetic and territorial autonomy

    2014-01-01

    Local citizen-led initiatives relating to energy are developing strongly in Anglo-Saxon countries and a growing body of research is examining their innovative potential. In France, similar grassroots initiatives – albeit with certain specificities – only began to emerge recently and so far, very few studies have dealt with them. The purpose of this article is to propose an exploratory and in-depth analysis of one advanced French case: Le Mene', a pioneer in local energy autonomy. We examine the conditions under which the initiative emerged and the processes through which a grassroots innovation is formed. In studying this case (interviews, analysis of documents), comparing it with other sources of data (expert interviews, comparative observation of other initiatives) and taking stock of various social sciences studies, we show that a social innovation was produced in Le Mene' through the hybridisation of actors, sociotechniques and discourses. This initiative was innovative not only in terms of the scope of the mechanisms implemented, but also in terms of the social organisation behind the development of the projects and the capacity to use energy production as a social resource. Finally, we reflect on the possible diffusion of these grassroots initiatives and their policy implications in France. - Highlights: • The case study is the Le Mené, a pioneer case for local energy autonomy. • This case is an emerging grassroots innovation in France. • Hybridisation (combining diversity and frames) is at the centre of the innovation. • This study focuses on the hybridisation of actors, sociotechniques and discourses. • Examines the potential diffusion of grassroots initiatives in France

    2017-01-01

    Renewable energy resources are often known as cost-effective and lucrative resources and have been widely developed due to environmental-economic issues. Renewable energy utilization even in small scale (e.g., microgrid networks) has attracted significant attention. Energy management in microgrid can be carried out based on the generating side management or demand side management. In this paper, portable renewable energy resource are modeled and included in microgrid energy management as a demand response option. Utilizing such resources could supply the load when microgrid cannot serve the demand. This paper addresses energy management and scheduling in microgrid including thermal and electrical loads, renewable energy sources (solar and wind), CHP, conventional energy sources (boiler and micro turbine), energy storage systems (thermal and electrical ones), and portable renewable energy resource (PRER). Operational cost of microgrid and air pollution are considered as objective functions. Uncertainties related to the parameters are incorporated to make a stochastic programming. The proposed problem is expressed as a constrained, multi-objective, linear, and mixed-integer programing. Augmented Epsilon-constraint method is used to solve the problem. Final results and calculations are achieved using GAMS24.1.3/CPLEX12.5.1. Simulation results demonstrate the viability and effectiveness of the proposed method in microgrid energy management. - Highlights: • Introducing portable renewable energy resource (PRER) and considering effect of them. • Considering reserve margin and sensitivity analysis for validate robustness. • Multi objective and stochastic management with considering various loads and sources. • Using augmented Epsilon-constraint method to solve multi objective program. • Highly decreasing total cost and pollution with PRER in stochastic state.

  4. The Social Perspective on the Renewable Energy Autonomy of Geographically Isolated Communities: Evidence from a Mediterranean Island

    Directory of Open Access Journals (Sweden)

    Fontina Petrakopoulou

    2017-02-01

    Full Text Available The use of renewable energy sources can provide a path toward sustainable development and regional energy independence. In particular, renewable-based energy autonomy constitutes a viable option in remote areas. This work presents a survey on the use of renewable energy as part of an energy autonomy plan on a Mediterranean island. The study also included personal communications with residents and local community leaders. The results show an overall positive attitude toward renewable energy applications. The majority of the respondents support the implementation of renewable-based, small-scale projects corresponding to local energy autonomy scenarios. They are, furthermore, convinced that a wider use of renewable technologies can reduce the environmental impact of conventional fuels. However, although people are aware of technologies widely used on the island, they are much less so when it comes to less prominent technologies (wave energy, fuel cells, etc.. People tend to be more open to installations of solar, wind and geothermal energy, while generally they dislike nuclear and coal power plants. Lastly, the majority of the respondents believe that local policies on energy issues should change, while they also perceive the lack of political will as one of the most important obstacles to the implementation of renewable technologies.

    Graphical abstract: In this study, we develop a portable high-efficiency electromagnetic energy harvesting system with supercapacitors that converts the energy of track vibrations into electricity. The generated electricity is stored in the supercapacitors and used in remote areas for safety facilities or in standby power supplies for rail-side equipment. The proposed system consists of a mechanical transmission and a rectifier. Acting as the energy input and transmission, Gears and a rack amplify the small vibrations of the track, and one-way bearings enhance efficiency by transforming bidirectional motion to unidirectional rotation. Supercapacitors are used in the energy harvesting system for the first time. The supercapacitors permit the storage of energy from rapidly changing transient currents and a steady power supply for external loads. The proposed system is demonstrated through dynamic simulations, which show the rapid response of the system. An efficiency of 55.5% is demonstrated in bench tests, verifying that the proposed electromagnetic energy harvesting system is effective and practical in renewable energy applications for railroads. - Highlights: • A frequently ignored source of energy, railroad track vibrations, is harvested. • A novel conversion mechanism is designed to maximize efficiency. • Supercapacitors are included in the electromagnetic energy harvesting system. • A portable design is proposed for wider application. - Abstract: As the demand for alternative sources of energy has increased, harvesting abundant environmental energy such as vibration energy including track vibrations in railway systems has attracted greater attention. In this study, we develop a portable high-efficiency electromagnetic energy harvesting system with supercapacitors that converts the energy of track vibrations into electricity.

    This study investigates experimentally the thermal perception of indoor environment for evaluating the ability of radiant panel heaters to produce thermal comfort for space occupants as well as the energy consumption in comparison with conventional portable natural convective heaters. The thermal perception results show that, compared with conventional convection heater, a radiantly heated office room maintains a lower ambient air temperature while providing equal levels of thermal perception on the thermal dummy head as the convective heater and saves up to 39.1% of the energy consumption per day. However, for human subjects' vote experiments, the results show that for an environmentally controlled test room at outdoor environment temperatures of 0C and 5C, using two radiant panel heaters with a total capacity of 580 W leads to a better comfort sensation than the conventional portable natural convective heater with a 670 W capacity, with an energy saving of about 13.4%. In addition, for an outdoor environment temperature of 10C, using one radiant panel heater with a capacity of 290 W leads to a better comfort sensation than the conventional convection heater with a 670 W capacity, with an energy saving of about 56.7%. From the analytical results, it is found that distributing the radiant panel heater inside the office room, one on the wall facing the window and the other on the wall close to the window, provides the best operative temperature distribution within the room.

    Wire-shaped supercapacitors (SCs) based on shape memory materials are of considerable interest for next-generation portable and wearable electronics. However, the bottleneck in this field is how to develop the devices with excellent electrochemical performance while well-maintaining recoverability and flexibility. Herein, a unique asymmetric electrode concept is put forward to fabricate smart wire-shaped SCs with ultrahigh energy density, which is realized by using porous carbon dodecahedra coated on NiTi alloy wire and flexible graphene fiber as yarn electrodes. Notably, the wire-shaped SCs not only exhibit high flexibility that can be readily woven into real clothing but also represent the available recoverable ability. When irreversible plastic deformations happen, the deformed shape of the devices can automatically resume the initial predesigned shape in a warm environment (about 35 °C). More importantly, the wire-shaped SCs act as efficient energy storage devices, which display high volumetric energy density (8.9 mWh/cm 3 ), volumetric power density (1080 mW/cm 3 ), strong durability in multiple mechanical states, and steady electrochemical behavior after repeated shape recovery processes. Considering their relative facile fabrication technology and excellent electrochemical performance, this asymmetric electrode strategy produced smart wire-shaped supercapacitors desirable for multifunctional portable and wearable electronics.

    2010-04-01

    This paper discusses a student project at Kettering University focusing on the design and construction of an energy efficient greenhouse climate control system. In order to maintain acceptable temperatures and stabilize temperature fluctuations in a portable plastic greenhouse economically, a computer controlled climate control system was developed to capture and store thermal energy incident on the structure during daylight periods and release the stored thermal energy during dark periods. The thermal storage mass for the greenhouse system consisted of a water filled base unit. The heat exchanger consisted of a system of PVC tubing. The control system used a programmable LabView computer interface to meet functional specifications that minimized temperature fluctuations and recorded data during operation. The greenhouse was a portable sized unit with a 5' x 5' footprint. Control input sensors were temperature, water level, and humidity sensors and output control devices were fan actuating relays and water fill solenoid valves. A Graphical User Interface was developed to monitor the system, set control parameters, and to provide programmable data recording times and intervals.

    As many regions of the United States experience rising temperatures, consumers have come to rely increasingly on cooling appliances (including portable air conditioners) to provide a comfortable indoor temperature. Home occupants sometimes use a portable air conditioner (PAC) to maintain a desired indoor temperature in a single room or enclosed space. Although PACs in residential use are few compared to centrally installed and room air conditioning (AC) units, the past few years have witnessed an increase of PACs use throughout the United States. There is, however, little information and few research projects focused on the energy consumption and performance of PACs, particularly studies that collect information from field applications of PACs. The operation and energy consumption of PACs may differ among geographic locations and households, because of variations in cooling load, frequency, duration of use, and other user-selected settings. In addition, the performance of building envelope (thermal mass and air leakage) as well as inter-zonal mixing within the building would substantially influence the ability to control and maintain desirable indoor thermal conditions. Lawrence Berkeley National Laboratory (LBNL) conducted an initial field-metering study aimed at increasing the knowledge and data related to PAC operation and energy consumption in the United States. LBNL performed its field-metering study from mid-April to late October 2014. The study, which monitored 19 sites in the Northeastern United States (4 in upstate New York and 15 near Philadelphia), collected real-time data on PAC energy consumption along with information regarding housing characteristics, consumer behavior, and environmental conditions that were expected to affect PAC performance. Given the limited number of test sites, this study was not intended to be statistically representative of PAC users in the United States but rather to understand the system response to the cooling demand and to

    Hand-held instruments that can be used to passively detect and identify sources of neutron radiation—either bare or obscured by neutron moderating and/or absorbing material(s)—in real time are of interest in a variety of nuclear non-proliferation and health physics applications. Such an instrument must provide a means to high intrinsic detection efficiency and energy-sensitive measurements of free neutron fields, for neutrons ranging from thermal energies to the top end of the evaporation spectrum. To address and overcome the challenges inherent to the aforementioned applications, four solid-state moderating-type neutron spectrometers of varying cost, weight, and complexity have been designed, fabricated, and tested. The motivation of this work is to introduce these novel human-portable instruments by discussing the fundamental theory of their operation, investigating and analyzing the principal considerations for optimal instrument design, and evaluating the capability of each of the four fabricated spectrometers to meet the application needs.

  14. Peak Load Regulation and Cost Optimization for Microgrids by Installing a Heat Storage Tank and a Portable Energy System

    2018-04-01

    Full Text Available With the rapid growth of electricity demands, many traditional distributed networks cannot cover their peak demands, especially in the evening. Additionally, with the interconnection of distributed electrical and thermal grids, system operational flexibility and energy efficiency can be affected as well. Therefore, by adding a portable energy system and a heat storage tank to the traditional distributed system, this paper proposes a newly defined distributed network to deal with the aforementioned problems. Simulation results show that by adding a portable energy system, fossil fuel energy consumption and daily operation cost can be reduced by 8% and 28.29%, respectively. Moreover, system peak load regulating capacity can be significantly improved. However, by introducing the portable energy system to the grid, system uncertainty can be increased to some extent. Therefore, chance constrained programming is proposed to control the system while considering system uncertainty. By applying Particle Swarm Optimization—Monte Carlo to solve the chance constrained programming, results show that power system economy and uncertainty can be compromised by selecting appropriate confidence levels α and β. It is also reported that by installing an extra heat storage tank, combined heat and power energy efficiency can be significantly improved and the installation capacity of the battery can be reduced.

  15. An experiment for urban energy autonomy in Seoul: The One ‘Less’ Nuclear Power Plant policy

    2014-01-01

    This study examines an experiment in energy self-sufficiency in Seoul, Republic of Korea, through a particular energy policy called the One Less Nuclear Power Plant (OLNPP) policy. We define an urban energy experiment as a purposive intervention for energy transition from an energy system based on nuclear and fossil fuels to one based on renewable energy and energy demand management. We suggest three findings. First, we find that the themes of our theoretical framework policy backgrounds, governance and policy contents have played important roles for Seoul’s energy experiments aimed at urban energy autonomy. In particular, political leadership based on the mayor’s previous experiences contributed significantly to the formation and implementation of this policy. Second, the OLNPP policy adds a social or moral dimension to urban energy policies. The norm change from an environmental and economic focus to a focus on the combination of social, environmental, and economic considerations is a unique contribution of the OLNPP policy to urban experiments in energy transition. Third, we find that experiments through purposive interventions serve as a means for facilitating urban energy governance where the actors involved can communicate and enhance their new ideas and practices. - Highlights: • We analyze One Less Nuclear Power Plant policy, with background, governance and content framework. • The OLNPP policy aims to achieve energy self-sufficiency at a local scale. • An urban energy experiment is for energy transition to renewable energy and energy demand management. • A unique contribution of Seoul’s energy experiment is changing norms by adding a moral dimension

    This report summarizes the BEAM modeling framework (Behavior, Energy, Mobility, and Autonomy) and its application to simulating plug-in electric vehicle (PEV) mobility, energy consumption, and spatiotemporal charging demand. BEAM is an agent-based model of PEV mobility and charging behavior designed as an extension to MATSim (the Multi-Agent Transportation Simulation model). We apply BEAM to the San Francisco Bay Area and conduct a preliminary calibration and validation of its prediction of charging load based on observed charging infrastructure utilization for the region in 2016. We then explore the impact of a variety of common modeling assumptions in the literature regarding charging infrastructure availability and driver behavior. We find that accurately reproducing observed charging patterns requires an explicit representation of spatially disaggregated charging infrastructure as well as a more nuanced model of the decision to charge that balances tradeoffs people make with regards to time, cost, convenience, and range anxiety.

    1998-12-01

    The study of adapting and evolving autonomous agents should be based on a complex systems-theoretic framework which requires both self-organizing and symbolic dimensions. An inclusive framework based on the notions of semiotics and situated action is advanced to build models capable of representing, as well as evolving in their environments.Such undertaking is pursued by discussing the ways in which symbol and self-organization are irreducibly intertwined in evolutionary systems. With this semiotic view of self-organization and symbols, the authors re-think the notion of autonomy of evolving systems, and show that evolutionary systems are characterized by a particular type of syntactic autonomy. Recent developments in emergent computation in cellular automata are discussed as examples of the emergence of syntactic autonomy in computational environments. New experiments emphasizing this syntactic autonomy in cellular automata are presented.

    Professional autonomy may represent the first step to implementing measures that will allow CRNAs to attain a level of independent practice consistent with their clinical and educational training. Autonomy is regarded as an essential ingredient of professionalism and confers independent function at the individual practitioner level. The principle of autonomy refers to the individual's capacity to make independent decisions based on the assumption that he or she possesses the cognitive, psychological, and emotional faculties to make rational decisions. Nursing practice meets the first two criteria of professionalism--competence and dedication to an important social good. The third criterion of professionalism, autonomy, has been a focal point for controversy since the late nineteenth century, in which obedience to supervisors and physicians remained a central focus of nursing ethics teaching until the advent of feminism in the 1970s. This article presents a thorough analysis of these concepts with some thoughts on how understanding the fundamental precepts and further research may not only help maintain the current level of CRNA professional autonomy but serve to guide us to become more autonomous in the future.

    This paper describes the characterization of thin-film MEMS vibration energy harvesters based on aluminum nitride as piezoelectric material. A record output power of 85 µW is measured. The parasitic-damping and the energy-harvesting performances of unpackaged and packaged devices are investigated. Vacuum and atmospheric pressure levels are considered for the packaged devices. When dealing with packaged devices, it is found that vacuum packaging is essential for maximizing the output power. Therefore, a wafer-scale vacuum package process is developed. The energy harvesters are used to power a small prototype (1 cm 3 volume) of a wireless autonomous sensor system. The average power consumption of the whole system is less than 10 µW, and it is continuously provided by the vibration energy harvester

    Highlights: • Solar based refrigeration systems with energy storage are proposed. • Thermodynamic and economic assessments are applied. • Cost of the pumped-hydro storage quadruples the hydrogen storage option. • A case study is made for the city of Aleppo in Syria as an emergency region. - Abstract: This study aims to investigate performance and cost aspects of a solar powered portable cooling system to conserve first aid supplies for off-grid areas with energy storage. Due to the intermittent nature of solar energy availability, two energy storage options are considered for a stationary system. Additional to the standalone system without energy storage, hydrogen is selected to be the storage medium by considering electrolysis at day time, and use of a hydrogen fuel cell unit at night time. This system consists of solar photovoltaic cells, a Polymer Exchange Membrane (PEM) electrolysis unit (PEME), hydrogen tank, a PEM fuel cell unit (PEMFC), and a vapor compression refrigeration (VCR) system to condition a container rated with ∼11 kW cooling load. The second system utilizes pumped – hydro storage (PHS) technology using a simple pump – turbine couple by storing water at a higher reservoir during day time and utilizing it to produce hydro power at night. Existence of higher reservoir brings a significant additional cost for the PHS system, making this configuration almost four times more costly than that of the hydrogen storage option, even though the storage efficiency of the PHS system is significantly higher than the hydrogen storage.

  3. Energy Link Optimization in a Wireless Power Transfer Grid under Energy Autonomy Based on the Improved Genetic Algorithm

    Directory of Open Access Journals (Sweden)

    Zhihao Zhao

    2016-08-01

    Full Text Available In this paper, an optimization method is proposed for the energy link in a wireless power transfer grid, which is a regional smart microgrid comprised of distributed devices equipped with wireless power transfer technology in a certain area. The relevant optimization model of the energy link is established by considering the wireless power transfer characteristics and the grid characteristics brought in by the device repeaters. Then, a concentration adaptive genetic algorithm (CAGA is proposed to optimize the energy link. The algorithm avoided the unification trend by introducing the concentration mechanism and a new crossover method named forward order crossover, as well as the adaptive parameter mechanism, which are utilized together to keep the diversity of the optimization solution groups. The results show that CAGA is feasible and competitive for the energy link optimization in different situations. This proposed algorithm performs better than its counterparts in the global convergence ability and the algorithm robustness.

    In developing their Site Treatment Plans (STPs), many of the Department of Energy installations identified some form of portable treatment, to facilitate compliant disposition of select mixed low-level wastestreams. The Environmental Management Office of Science and Technology requested that a systems study be performed to better define the potential role of portable treatment with respect to mixed low-level waste, highlight obstacles to implementation, and identify opportunities for future research and development emphasis. The study was performed by first establishing a representative set of mixed waste, then formulating portable treatment system concepts to meet the required processing needs for these wastes. The portable systems that were conceptualized were evaluated and compared to a fixed centralized treatment alternative. The system evaluations include a life-cycle cost analysis and an assessment of regulatory, institutional, and technical issues associated with the potential use of portable systems. The results of this study show that when all costs are included, there are no significant cost differences between portable systems and fixed systems. However, it is also emphasized that many uncertainties exist that could impact the cost of implementing portable treatment systems. Portable treatment could be made more attractive through private sector implementation, although there is little economic incentive for a commercial vendor to develop small, specialized treatment capabilities with limited applicability. Alternatively, there may also be valid reasons why fixed units cannot be used for some problematic wastestreams. In any event, there are some site-specific problems that still need to be addressed, and there may be some opportunity for research and development to make a positive impact in these areas.

    A proton exchange membrane (PEM) fuel cells (FCs) with ultracapacitor (UC) and battery (BT) hybrid system has fast transient response compare to stand alone FCs. This hybrid system is promising candidates for environmentally friendly alternative energy sources. An energy management system design and control strategy was introduced in this study. The energy management strategy FC/ UC/ BT hybrid system model has been developed and the control strategy was programmed in the LabVIEWTM environment and implemented using National Instrument (NI) devices. The energy management strategy is able to manage the energy flow between the main power source (FCs) and auxiliary sources (UC and BT). To control the hybrid system and achieved proper performance, a controller circuit was developed with the three energy sources aligned in parallel to deliver the requested power. The developed model demonstrates the proportion power from the FC, UC and BT under various load demand. Experimental results demonstrate that FC/ UC/ BT hybrid system operated automatically with the varying load condition. The experimental results are presented; showing that the proposed strategy utilized the characteristic of both energy storage devices thus satisfies the load requirement. (author)

    Nuclear-based electric and steam generation has traditionally been limited to large-scale plants that require enormous capital and infrastructure. A new wave of nuclear reactors is ready for introduction into locales and industry that previously have been unable to take advantage of the clean, safe, and cheap energy nuclear affords. One of these 'new kids on the block' is the Hyperion Power Module (HPM), an original design developed in Los Alamos National Laboratory. Through the U.S. government's technology transfer initiative, the exclusive license to develop and commercialize the invention has been granted to Hyperion Power Generation (HPG). The Hyperion Power 'Module' was specifically designed for applications in remote areas where cost, safety, and security is of concern. The Hyperion Power Module, a self-contained, self-regulating reactor, is breaking new ground in the nuclear industry and filling a heretofore-unmet need for moderately sized power applications either distributed or dedicated. Employing proven science in a new way, Hyperion provides a safe, clean power solution for remote locations or locations that must currently employ less than satisfactory alternatives. Generating nearly 70 megawatts of thermal energy and from 25 to 30 megawatts of electrical energy, the Power Module is the world's first small mobile reactor, taking advantage of the natural laws of chemistry and physics and leveraging all of the engineering and technology advancements made over the last fifty years. The HPM is comparable in size to a deep residential hot tub and is designed to be cited underground in a containment vessel. The CEO of Hyperion will outline the benefits of small nuclear reactors by examining their impact on the U.S. economy, national security, the environment, remote regions, and developing nations. The speaker will also focus on the four main applications of the Hyperion Reactor: military bases; oil and gas recovery and refining; remote communities lacking

    DEFF Research Database (Denmark)

    Lind, Jonas Krog

    The formal autonomy of universities in Europe has generally increased over recent decades. However, new forms of accountability measures and more indirect state steering have accompanied this development, making it difficult to assess the actual autonomy. The article addresses this problem...... by applying the sensemaking approach to the study of organizational autonomy. Enacted autonomy is suggested as a new conceptualization that challenges the basic assumption in studies on formal autonomy that autonomy is only about external constraints on action. It does so by insisting on the active subjects...... in the enactment of the environment, thereby questioning the validity of a clear distinction between what is internal and what is external to an organization. By acknowledging the subjective dimension of autonomy, a set of stylized identities is developed as a tool for understanding the enactment of autonomy...

  15. Respect for rational autonomy.

    Science.gov (United States)

    Walker, Rebecca L

    2009-12-01

    The standard notion of autonomy in medical ethics does not require that autonomous choices not be irrational. The paper gives three examples of seemingly irrational patient choices and discusses how a rational autonomy analysis differs from the standard view. It then considers whether a switch to the rational autonomy view would lead to overriding more patient decisions but concludes that this should not be the case. Rather, a determination of whether individual patient decisions are autonomous is much less relevant than usually considered in determining whether health care providers must abide by these decisions. Furthermore, respect for rational autonomy entails strong positive requirements of respect for the autonomy of the person as a rational decision maker. The rationality view of autonomy is conceptually stronger than the standard view, allows for a more nuanced understanding of the practical moral calculus involved in respecting patient autonomy, and promotes positive respect for patient autonomy.

    A simple but very accurate portable dosimeter is described for indicating the intensity of ionizing radiation, comprising, as a unit: (a) a radiation-detection chamber having a pair of parallel, facing, electrically-conducting, radiation-permeable electrodes spaced from each other to define a volume for a gas which is ionized by the radiation when exposed thereto; (b) electric potential supply means connected across the electrodes for attracting the gas ions to the electrodes and transferring their charge to the electrodes; (c) detection circuit means connected across the electrodes and having at least one of high-frequency electromagnetic- and radiation-sensitive components for detecting the charge on the electrodes and indicating therefrom a representation of the intensity of the radiation; (d) radiation shield means surrounding the radiation-sensitive components of the detection circuit means for shielding the latter from the ionizing radiation; (e) electric shield means surrounding the sensitive components of the detection circuit means for shielding the latter from electromagnetic interference including any caused by the ionizing radiation; and (f) ion shield means potting the ion-sensitive components for shielding them from radiation-caused ambient ionization; whereby the entire dosimeter may be assembled as the unit and portably transported into various radiation sources

  19. Autonomy: Life and Being

    Science.gov (United States)

    Williams, Mary-Anne

    This paper uses robot experience to explore key concepts of autonomy, life and being. Unfortunately, there are no widely accepted definitions of autonomy, life or being. Using a new cognitive agent architecture we argue that autonomy is a key ingredient for both life and being, and set about exploring autonomy as a concept and a capability. Some schools of thought regard autonomy as the key characteristic that distinguishes a system from an agent; agents are systems with autonomy, but rarely is a definition of autonomy provided. Living entities are autonomous systems, and autonomy is vital to life. Intelligence presupposes autonomy too; what would it mean for a system to be intelligent but not exhibit any form of genuine autonomy. Our philosophical, scientific and legal understanding of autonomy and its implications is immature and as a result progress towards designing, building, managing, exploiting and regulating autonomous systems is retarded. In response we put forward a framework for exploring autonomy as a concept and capability based on a new cognitive architecture. Using this architecture tools and benchmarks can be developed to analyze and study autonomy in its own right as a means to further our understanding of autonomous systems, life and being. This endeavor would lead to important practical benefits for autonomous systems design and help determine the legal status of autonomous systems. It is only with a new enabling understanding of autonomy that the dream of Artificial Intelligence and Artificial Life can be realized. We argue that designing systems with genuine autonomy capabilities can be achieved by focusing on agent experiences of being rather than attempting to encode human experiences as symbolic knowledge and know-how in the artificial agents we build.

  20. The Evolution of Autonomy.

    There can be little doubt, at least in the Western world, that autonomy is theruling principle in contemporary bioethics. In spite of its 'triumph' however,the dominance of the utilitarian concept of autonomy is being increasinglyquestioned. In this paper, I explore the nature of autonomy, how it came todisplace the Hippocratic tradition in medicine and how different conceptsof autonomy have evolved. I argue that the reduction of autonomy to'the exercise of personal choice' in medicine has led to a 'tyranny of autonomy' which can be inimical to ethical medical practice rather than conducive to it.I take the case of Kerrie Wooltorton as an illustration of how misplacedadherence to respect for patient autonomy can lead to tragic consequences.An analysis of autonomy based on the work of Rachel Haliburton isdescribed and applied to the role of autonomy in a recent bioethicaldebate--that arising from Savulescu's proposal that conscientious objection by health-care professionals should not be permitted in the NHS. Inconclusion, I suggest Kukla's concept of conscientious autonomy as onepromising pathway to circumvent both the limitations and adverse effectsof the dominance of current (mis)understandings of autonomy in biomedical ethics.

    This publication contains proceedings of a conference on methanization projects and techniques, notably in rural areas (there were 140 rural installations in France in 2014 and 20 centralised ones). Contributions thus give an overview of the present development of this sector, and of its perspectives over the medium to long term. A first set of contributions addressed the performance of a panel of farm-based and centralised methanization installations with technical, energy, environmental, agronomic and social assessments for 8 units (lessons learned from installation follow-up, recommendations for operation optimisation of 2 units), and a profitability study performed on 21 installations (lessons learned, profitability evolution for 2 installations). The second set of contributions addressed development perspectives of the methanization sector over the medium to long term. Contributions addressed the following issues: how to mobilise and process bio-wastes from big producers, other possible sources (energetic crops, intermediate crops for energy purposes or CIVE or crop residues), the use of digestate to reduce the use of mineral fertilizers, and emerging energetic valorisations of biogas. A last part presents the Methanization Autonomy Nitrogen Energy Plan (the EMAA plan) which aims at managing and valorising nitrogen (notably from breeding effluents), at developing a French model of agricultural methanization. The stakes of methanization for energy transition are outlined, and the operation of a methanization installation is described

    An easily foldable and portable triboelectric-electromagnetic generator (TEMG) based on two polymer/Al layers and one copper coil has been designed to harvest ambient mechanical energy, where the copper coil is used both as a spring to achieve contact and separation of triboelectric layers and as a circuit to collect electromagnetic-induced electricity. The output performance of the TEMG is approximately reproducible after being folded many times. The working mechanism is discussed. The output performance of individual triboelectric generator (TEG) and electromagnetic generator (EMG) are systematically investigated. The maximum output current, voltage, and power are obtained to be 32.2 μA, 500 V, and 2 mW for the TEG, and 4.04 mA, 30 mV, and 15.8 μW for the EMG, respectively. The TEG with a higher internal resistance can be used as a current source, while the EMG with a lower resistance can be used as a voltage source. It can be used as a mobile light source via integrating the TEMG in clothes or bags, and as a self-powered gas flow sensor for detecting respiratory rate, which has a potential application in medical diagnoses. The simple structure and easy portability of the TEMG could be used widely in daily life to harvest ambient energy for electronic devices.

    The effective use of near water equivalent organic plastic scintillators (OPS) for radiation dosimetry with high-energy sources under laboratory conditions is recognized. In this work, an OPS-based dosimeter using a photodiode combined with improved solid state detection and signal processing techniques has been developed; it offers the potential for the construction of a stable and fully portable dosimeter which will extend the useful range of measurement beyond the usual MeV area and provide reliable readings down to sub-100 keV X-ray energy levels. In these experiments, the instrument described has been used for the dosimetry of INTRABEAM intraoperative radiotherapy (IORT) equipment at distances as low as 1.8 mm from the effective source, i.e., 0.2 mm from the X-ray probe surface. Comparison is shown with dosimetry measurements made using the calibrated reference ion chamber supplied by the IORT equipment manufacturer. (author)

    On the north coast of present-day Peru flourished approximately between 50 and 700 AD, the Moche civilization. It was an advanced culture and the Moche were sophisticated metalsmiths, so that they are considered as the finest producers of jewels and artefacts of the region. The Moche metalworking ability was impressively demonstrated by the objects discovered by Walter Alva and coworkers in 1987, in the excavations of the 'Tumbas Reales de Sipan'. About 50 metal objects from these excavations, now at the namesake Museum, in Lambayeque, north of Peru, were analyzed with a portable equipment using energy-dispersive X-ray fluorescence. This portable equipment is mainly composed of a small size X-ray tube and a thermoelectrically cooled X-ray detector. Standard samples of gold and silver alloys were employed for quantitative analysis. It was determined that the analyzed artefacts from the 'Tumbas Reales de Sipan' are mainly composed of gold, silver and copper alloys, of gilded copper and of tumbaga, the last being a poor gold alloy enriched at the surface by depletion gilding, i.e. removing copper from the surface.

    This work presents the evaluation of the applicability and sensitivity of a portable detection device specially designed for in vivo measurement of high-energy photon emitters in the human body. The calibration was performed at the In-Vivo Monitoring Laboratory of the IRD. The equipment consists of a lead-collimated NaI (Tl) 3″ x 3″ scintillation detector assembled on a tripod. The detector and its compact associated electronics are connected via USB cable to a portable PC. Spectrum acquisition and analysis is controlled by specific commercially available software. The calibration was performed using a standard liquid source of 152 Eu contained in 3 L polyethylene bottles. The evaluation of the system is based on the estimation of the minimum committed effective doses associated to the minimum detectable activities, calculated using current biokinetic and dosimetric models available in the literature. The dose detection limits for selected radionuclides of interest in an emergency scenario have shown to be far below 1 mSv allowing the system to be useful in accident situations. (author)

  12. Standby-battery autonomy versus power quality

    Science.gov (United States)

    Bitterlin, Ian F.

    Batteries are used in a wide variety of applications as an energy store to bridge gaps in the primary source of supplied power for a given period of time. In some cases this bridging time, the battery's "autonomy", is fixed by local legislation but it is also often set by historically common practices. However, even if common practice dictates a long autonomy time, we are entering a new era of "cost and benefit realism" underpinned by environmentally friendly policies and we should challenge these historical practices at every opportunity if it can lead to resource and cost savings. In some cases the application engineer has no choice in the design autonomy; either follow a piece of local legislation (e.g. 4 h autonomy for a "life safety" application), or actually work out what is needed! An example of the latter would be for a remote site, off-grid, using integrated wind/solar power (without emergency generator back-up) where you may have to design-in several days' battery autonomy. This short paper proposes that a battery's autonomy should be related to the time expected for the system to be without the primary power source, balanced by the capital costs and commercial risk of power failure. To discuss this we shall consider the factors in selecting the autonomy time and other related aspects for high voltage battery systems used in facility-wide uninterruptible power supply (UPS) systems.

  18. Anagogy of autonomy.

    Boyd, A L

    2000-07-01

    The philosophical and ethical concept of autonomy is herein examined, ex post facto, using an existential lens to examine the process of a personal friend's dying. Anagogy, defined as interpretation of a word, passage, or text that finds beyond the literal, allegorical, and moral senses a fourth and ultimate spiritual or mystical sense, is intended to enlarge the understanding of the use of autonomy in this case. The idea of personhood linked inextricably to reason is, therefore, understood as empowering an individual to choose among various actions, to define and redefine life goals, and to give priority to selected values and moral tenants, which reveal a moral hermeneutic. Conditions and circumstances, existentially exposed, limit choice in unexpected ways, such that the predicted value of autonomy is vulnerable to misuse or misunderstanding. The intent to respect the dignity of every person is central to the philosophy of Respect for Persons ethics, and assumes that autonomy, as freedom of the moral agent, is a moral duty. Implicit reality of freedom is, in a practical sense, essential to being rational agents who can thereby exercise informed choice. The moral law, law of freedom, involves the autonomy of the will and an ultimate end to which all action is directed. Defined as the highest good, morality unites virtue and happiness by ascribing the ultimate end sought as God. The freedom to use rational will finds principles within its own rational nature. The ability to create maxims is autonomy of the will, which equates with the dignity of persons. My recent experience as a companion to a personal friend with a terminal illness inspired me to re-evaluate the concept of autonomy as it is too often interpreted in modern ethical discourse as a individualistic right of choice as opposed to the hermeneutic of dignity of person. This paper describes a shift of position in understanding the paradox of autonomy in this existential context.

  19. Autonomy and hyperthyroidism

    The significance of autonomy in iodine-deficiency goiter for the development of hyperthyroidism was investigated. (1) In 171 of 426 consecutive patients high-resolution quantitative scintiscans showed signs suggestive of autonomy. With increasing 99mTc uptake by the thyroid their TT3 levels were found to rise progressively during suppression, while their pre-suppression TSH levels dropped progressively. This suggests global sup(99m)Tc uptake by the thyroid during suppression to be a useful indicator of the functional significance of autonomy. (2) Based on 326 patients with hyperthyroidism a system for differentiating between autonomy-related and immunogenic disease was developed and validated prospectively in another 162 patients with hyperthyroidism by assaying for thyroid stimulating antibodies (TSAb). TSAb was found to be present in 82% of the 77 patients diagnosed as having immunogenic hyperthyroidism and in only 8% of the 85 patients with autonomy-related hyperthyroidism. Our results support the assumption that autonomy in iodine-deficiency goiter plays a major role in the development of hyperthyroidism, while autoimmune processes appear to be of secondary importance.

    Plasma Focus devices are pulsed sources of X and neutron radiation from intense electrical discharges in deuterium. Classically these devices operate at energies between a few KJ to 1 MJ. In this work we present the design and feasibility studies of a Plasma Focus operating at energies close to 1 Joule. Experimental evidence of focalization is presented, and the optimum parameter relations at such low energies are discussed. The results indicate the device will be able to emit pulses about 1000 neutrons per J. (author) [es

    Highlights: • A portable system based on hydrogen and single air breathing PEM fuel cell. • Control electronics designed for low single cell voltage (0.5–0.8 V). • Forced air convection and anode purging required to help water management. • Application consisting of a propeller able to display a luminous message. • Up to 20 h autonomy with continuous 1.1 W consumption, using 1 g H 2 . - Abstract: A portable system for power generation based on hydrogen and a single proton exchange membrane fuel cell (PEMFC) has been built and operated. The fuel cell is fed in the anode with hydrogen stored in a metal hydrides cartridge, and in the cathode with oxygen from quiescent ambient air (‘air breathing’). The control electronics of the system performs DC–DC conversion from the low voltage (0.5–0.8 V) and high current output (200–300 mA cm −2 ) of the single fuel cell, up to 3.3 V to power an electronic application. System components assist fuel cell operation, including an electronic valve for anode purging, a fan in front of the open cathode, two supercapacitors for auxiliary power requirements, four LED lights, and a display screen. The influence of the system components on fuel cell behaviour is analyzed. The cathode fan and anodic purging help excess water removal from the electrodes leading to steadier cell response at the expense of extra power consumption. The power system is able to provide above 1 W DC electricity to an external application during 20 h using 1 g of H 2 . An application consisting of a propeller able to display a luminous message is chosen to test system. It is shown that one single air breathing PEM fuel cell powered with hydrogen may provide high energy density and autonomy for portable applications

  3. Understanding nurse practitioner autonomy.

    2015-02-01

    This Gadamerian hermeneutic study was undertaken to understand the meaning of autonomy as interpreted by nurse practitioners (NPs) through their lived experiences of everyday practice in primary health care. A purposive sample of nine NPs practicing in primary health care was used. Network sampling achieved a broad swath of primary care NPs and practice settings. Data were collected by face-to-face interviews. Because NP autonomy is concerned with gender and marginalization, Gilligan's feminist perspective was utilized during interpretive analysis. Having Genuine NP Practice was the major theme, reflecting the participants' overall meaning of their autonomy. Practicing alone with the patient provided the context within which participants shaped the meaning of Having Genuine NP Practice. Having Genuine NP Practice had four subthemes: relationships, self-reliance, self-empowerment, and defending the NP role. The understanding of Having Genuine NP Practice will enable NPs to articulate their autonomy clearly and better influence healthcare reform. Implications for advanced practice nursing education include integrating findings into classroom discussion to prompt self-reflection of what autonomy means and socialization to the NP role. ©2014 American Association of Nurse Practitioners.

    Primary beam spectra were obtained for an X-ray industrial equipment (40-150 kV), and for a clinical mammography apparatus (25-35 kV) from beams scattered at angles close to 90 o , measured with a CdTe Compton spectrometer. Actual scattering angles were determined from the Compton energy shift of characteristic X-rays or spectra end-point energy. Evaluated contribution of coherent scattering amounts to more than 15% of fluence in mammographic beams. This technique can be used in clinical environments.

    Tissue equivalent proportional counters simulating solid volumes a few micrometers in diameter make exceptionally versatile neutron detectors. Since they are nearly tissue equivalent, the energy deposited in the detector is a good measure of the dose in tissue. The well known relationships between microdosimetric parameters and linear energy transfer provide several convenient options for calculating dose equivalent. However, this technique has found only very limited application in routine dosimetry due to the complexity of the electronics and of the spectral information collected. Recent developments in microelectronics combined with improved techniques for building proportional counters have now made it possible to develop a fully automated portable proportional counter system. A prototype device based on these principles has been developed for NASA as a potential space shuttle experiment. This system includes separate detectors and electronics to measure dose and the fluence of high energy heavy ions. Use of an internal alpha particle source provides reliable energy calibration so that the precision of dose measurements can be checked frequently. The dose monitoring detector simulates a 2 μm diameter sphere. The electronics system includes a low noise charge-sensitive preamplifier housed in the detector base, two analog-to-digital converters with amplifier gains differing by a factor of twenty, a pair of 128 channel memories and a CMOS microcomputer which controls the system and automatically calculates dose and dose equivalent. In order to simplify the calculations, the detector gain is automatically maintained at a preset value by adjusting the anode voltage

  6. Autonomy in chimpanzees.

    Beauchamp, Tom L; Wobber, Victoria

    2014-04-01

    Literature on the mental capacities and cognitive mechanisms of the great apes has been silent about whether they can act autonomously. This paper provides a philosophical theory of autonomy supported by psychological studies of the cognitive mechanisms that underlie chimpanzee behavior to argue that chimpanzees can act autonomously even though their psychological mechanisms differ from those of humans. Chimpanzees satisfy the two basic conditions of autonomy: (1) liberty (the absence of controlling influences) and (2) agency (self-initiated intentional action), each of which is specified here in terms of conditions of understanding, intention, and self-control. In this account, chimpanzees make knowledge-based choices reflecting a richly information-based and socially sophisticated understanding of the world. Finally, two major theories of autonomy (Kantian theory and two-level theory) are rejected as too narrow to adequately address these issues, necessitating the modifications made in the present approach.

  7. [What is patient autonomy?

    Science.gov (United States)

    Durand, Guillaume

    What does patient autonomy mean? If an autonomous choice is defined as an objective and rational choice, is the doctor's prescription not always the best route? Our contemporary democracies are marked by moral and religious pluralism which obliges society to respect a multiplicity of choices of existence. Three levels are important in terms of autonomy: a range of intellectual capacities, freedom with regard to constraints (external and internal), the capacity to be in control of one's existence.

    There are numerous instances where the availability of a portable high-energy radiography machine that could be transported to the inspection site with relative ease would save time, money, and make radiography of permanent installations, such as bridges, possible. One such machine, the Minac built by Schoenberg Radiation Inc., is commercially available. It operates at 9.3 GHz, has an electron energy on target of 3.5 MeV, and an output dose rate of 100 R/min. A second portable accelerator, recently completed at the Los Alamos National Laboratory, operates at 2.998 GHz, has electron energies on target of 6, 8, and 10 MeV, and an output dose rate of 800 R/min at 8 MeV. This paper discusses the need for and applications of portable accelerators for radiography. Physical characteristics and beam parameters of both machines are examined in detail. Problems of operating at higher frequencies to further minimize size and weight are discussed

    2009-01-01

    Over the last several years, as cesarean deliveries have grown increasingly common, there has been a great deal of public and professional interest in the phenomenon of women ‘choosing’ to deliver by cesarean section in the absence of any specific medical indication. The issue has sparked intense conversation, as it raises questions about the nature of autonomy in birth. Whereas mainstream bioethical discourse is used to associating autonomy with having a large array of choices, this conception of autonomy does not seem adequate to capture concerns and intuitions that have a strong grip outside of this discourse. An empirical and conceptual exploration of how delivery decisions ought to be negotiated must be guided by a rich understanding of women’s agency and its placement within a complicated set of cultural meanings and pressures surrounding birth. It is too early to be ‘for’ or ‘against’ women’s access to cesarean delivery in the absence of traditional medical indications - and indeed, a simple pro- or con- position is never going to do justice to the subtlety of the issue. The right question is not whether women ought to be allowed to choose their delivery approach, but rather, taking the value of women’s autonomy in decision-making around birth as a given, what sorts of guidelines, practices, and social conditions will best promote and protect women’s full inclusion in a safe and positive birth process.

    Cities and communities have a constitutionally secured autonomy. What means this within the range of the protection of climate and resources? May communities take over global tasks, or are these limited in their local sphere of activity? In the meantime, in most German city halls something is done for the employment of renewable energies. Under this aspect, the author of the contribution under consideration reports at first on a comprehensive jurisprudential answer on the fundamental question which local tasks are entitled to the cities and communities and how this affects the range of climate protection and resources protection. Moreover, up-to-date particularly disputed local solar statutes are evaluated legally.

  1. Autonomy and the principle of respect for autonomy.

    Science.gov (United States)

    Gillon, R

    1985-06-15

    Autonomy is defined as the capacity to think, decide, and act freely and independently on the basis of such thought and decisions. Three types of autonomy are distinguished: autonomy of thought, which embraces the wide range of human intellectual activities called "thinking for oneself"; autonomy of will, or the capacity to decide to do things on the basis of one's deliberations; and autonomy of action, the absence of which is illustrated by the situation of a patient whose voluntary muscles are paralyzed by curariform drugs and who thus cannot tell the surgeon that the anesthetist has forgotten the nitrous oxide. Autonomy is viewed as a prerequisite for all the virtues, rather than as a virtue in its own right. The arguments of Immanuel Kant and John Stuart Mill concerning the principle of respect for autonomy are summarized as exemplars respectively of the deontological and utilitarian philosophical approaches.

  2. Law, autonomy and advance directives.

    Science.gov (United States)

    Willmott, Lindy; White, Ben; Mathews, Ben

    2010-12-01

    The principle of autonomy underpins legal regulation of advance directives that refuse life-sustaining medical treatment. The primacy of autonomy in this domain is recognised expressly in the case law, through judicial pronouncement, and implicitly in most Australian jurisdictions, through enactment into statute of the right to make an advance directive. This article seeks to justify autonomy as an appropriate principle for regulating advance directives and relies on three arguments: the necessity of autonomy in a liberal democracy; the primacy of autonomy in medical ethics discourse; and the uncontested importance of autonomy in the law on contemporaneous refusal of medical treatment. This article also responds to key criticisms that autonomy is not an appropriate organising principle to underpin legal regulation of advance directives.

    A significant level of debate and confusion has surrounded the meaning of the terms autonomy and automation. Automation is a multi-dimensional concept, and we propose that Remotely Piloted Aircraft Systems (RPAS) automation should be described with reference to the specific system and task that has been automated, the context in which the automation functions, and other relevant dimensions. In this paper, we present definitions of automation, pilot in the loop, pilot on the loop and pilot out of the loop. We further propose that in future, the International Civil Aviation Organization (ICAO) RPAS Panel avoids the use of the terms autonomy and autonomous when referring to automated systems on board RPA. Work Group 7 proposes to develop, in consultation with other workgroups, a taxonomy of Levels of Automation for RPAS.

    Can actions caused by emotions be free and autonomous? The rationalist conception of autonomy denies this. Only actions done in the light of reflective choices can be autonomous and hence free. I argue that the rationalist conception does not make room for akratic actions, that is, free and intentional actions performed against the agent’s best judgement. I then develop an account inspired by Harry Frankfurt and David Shoemaker, according to which an action is autonomous when it is determined...

  5. The Autonomy of Deportation

    Directory of Open Access Journals (Sweden)

    Nicholas de Genova

    2017-06-01

    Full Text Available As ostensibly unwanted or undesirable non-citizens, the utter disposability of deportees appears to be finally and conclusively verified by deportation as a sovereign state power’s perfunctory and mundane act of 'taking out the trash.' Hence, it is no accident that, etymologically, the origins of the very word 'deportation' would indicate a carrying away, a removal, a disposal. The eradication of deportees’ individual lives — their personal identities and life trajectories — emerges as a frightfully routine and prosaic fact of deportation. In spite of the sheer violence of the ruptures inflicted though deportation, however, those who have been rendered the objects of this power persistently reassert their own subjectivity. Ethnographic insights into the lived struggles of the deported (as well as their loved ones and communities elucidates the enduring subjectivity of those who have been made the objects of such sovereign acts of state power and subjected to deportation's techniques of eradication, and illustrates the stubborn incorrigibility of human life against the myriad forces that would seek to enforce its precarity and disposability. In the post-deportation condition, we confront anew the elementary and elemental human freedom of movement, and the incorrigibility of the autonomy and subjectivity of migration. Much as the autonomy of migration instigates a contest in which state power never has the first word, what we may now conceive as the autonomy of deportation — an autonomy and subjectivity of the deported within and against their predicaments of deportation — similarly ensures that state power never has the last word, either.

    This article seeks to explore and analyze the relationship between autonomy and trust, and to show how these findings could be relevant to medical ethics. First, I will argue that the way in which so-called "relational autonomy theories" tie the notions of autonomy and trust together is not entirely satisfying Then, I will introduce the so-called Encapsulated Interest Account as developed by Russell Hardin. This will bring out the importance of the reasons for trust. What good reasons do we have for trusting someone? I will criticize Hardin's business model as insufficiently robust, especially in the context of health care, and then turn to another source of trust, namely, love. It may seem that trust-through-love is much better suited for the vulnerability that is often involved in health care, but I will also show that it has its own deficiencies. Good health care should therefore pay attention to both models of trust, and I will offer some tentative remarks on how to do this. © The Author 2015.

  8. Autonomy, recognition and education

    Directory of Open Access Journals (Sweden)

    Angelo Vitório Cenci

    2015-01-01

    Full Text Available This paper addresses Honneth’s concept of autonomy from two dimensions of his work, distinct, though inseparable. The first one is suggested through the subject’s positive practical self-relation linked to the patterns of reciprocal recognition of love, right and social esteem; the second is formulated as non-centered autonomy opposed to the present-day criticism of the modern autonomous subject encompassing three levels, namely: the capacity of linguistic articulation, the narrative coherence of life and the complementation of being guided by principles with some criteria of moral sensitivity to the context. We defend the position that, by metaphysically anchoring the concept of autonomy onto the intersubjective assumptions of his/her theory of the subject, and exploring it linked to the subject’s positive practical self-relation and to a non-centered meaning, Honneth has managed to renew it, which allows drawing important consequences of such effort to the field of education.

  9. Ignorance, information and autonomy.

    Science.gov (United States)

    Harris, J; Keywood, K

    2001-09-01

    People have a powerful interest in genetic privacy and its associated claim to ignorance, and some equally powerful desires to be shielded from disturbing information are often voiced. We argue, however, that there is no such thing as a right to remain in ignorance, where a fight is understood as an entitlement that trumps competing claims. This does not of course mean that information must always be forced upon unwilling recipients, only that there is no prima facie entitlement to be protected from true or honest information about oneself. Any claims to be shielded from information about the self must compete on equal terms with claims based in the rights and interests of others. In balancing the weight and importance of rival considerations about giving or withholding information, if rights claims have any place, rights are more likely to be defensible on the side of honest communication of information rather than in defence of ignorance. The right to free speech and the right to decline to accept responsibility to take decisions for others imposed by those others seem to us more plausible candidates for fully fledged rights in this field than any purported right to ignorance. Finally, and most importantly, if the right to autonomy is invoked, a proper understanding of the distinction between claims to liberty and claims to autonomy show that the principle of autonomy, as it is understood in contemporary social ethics and English law, supports the giving rather than the withholding of information in most circumstances.

  10. Autonomy and autonomy competencies: a practical and relational approach.

    Science.gov (United States)

    Atkins, Kim

    2006-10-01

    This essay will address a general philosophical concern about autonomy, namely, that a conception of autonomy focused on freedom of the will alone is inadequate, once we consider the effects of oppressive forms of socialization on individuals' formation of choices. In response to this problem, I will present a brief overview of Diana Meyers's account of autonomy as relational and practical. On this view, autonomy consists in a set of socially acquired practical competencies in self-discovery, self-definition, self-knowledge, and self-direction. This account provides a distinction between choices that express unreflectively internalized social norms and those that are the result of a critical 'self-reading'. I conclude that this practical conception of autonomy makes much higher demands upon nurses (and patients) than has previously been thought. In fact, if nurses are to be expected to genuinely promote autonomy, they are going to need specific training in counselling-type communication skills.

    1 - Description of program or function: PICL is a subroutine library that can be used to develop parallel programs that are portable across several distributed-memory multi-processors. PICL provides a portable syntax for key communication primitives and related system calls. It also provides portable routines to perform certain widely- used, high-level communication operations, such as global broadcast and global summation. PICL provides execution tracing that can be used to monitor performance or to aid in debugging. 2 - Restrictions on the complexity of the problem: PICL is a compatibility library built on top of the native multiprocessor operating system and message passing primitives. Thus, the portability of PICL programs is not guaranteed, being a function of idiosyncrasies of the different platforms. Predictable differences are captured with standard error trapping routines. PICL is a research tool, not a production software system

    Broten, Gregory S.; Monckton, Simon P.; Collier, Jack; Giesbrecht, Jared

    2006-05-01

    In 2002 Defence R&D Canada changed research direction from pure tele-operated land vehicles to general autonomy for land, air, and sea craft. The unique constraints of the military environment coupled with the complexity of autonomous systems drove DRDC to carefully plan a research and development infrastructure that would provide state of the art tools without restricting research scope. DRDC's long term objectives for its autonomy program address disparate unmanned ground vehicle (UGV), unattended ground sensor (UGS), air (UAV), and subsea and surface (UUV and USV) vehicles operating together with minimal human oversight. Individually, these systems will range in complexity from simple reconnaissance mini-UAVs streaming video to sophisticated autonomous combat UGVs exploiting embedded and remote sensing. Together, these systems can provide low risk, long endurance, battlefield services assuming they can communicate and cooperate with manned and unmanned systems. A key enabling technology for this new research is a software architecture capable of meeting both DRDC's current and future requirements. DRDC built upon recent advances in the computing science field while developing its software architecture know as the Architecture for Autonomy (AFA). Although a well established practice in computing science, frameworks have only recently entered common use by unmanned vehicles. For industry and government, the complexity, cost, and time to re-implement stable systems often exceeds the perceived benefits of adopting a modern software infrastructure. Thus, most persevere with legacy software, adapting and modifying software when and wherever possible or necessary -- adopting strategic software frameworks only when no justifiable legacy exists. Conversely, academic programs with short one or two year projects frequently exploit strategic software frameworks but with little enduring impact. The open-source movement radically changes this picture. Academic frameworks

    Turner, Philip R.

    1987-02-01

    Aerospace industry interest in autonomy and automation, given fresh impetus by the national goal of establishing a Space Station, is becoming a major item of research and technology development. The promise of new technology arising from research in Artificial Intelligence (AI) has focused much attention on its potential in autonomy and automation. These technologies can improve performance in autonomous control functions that involve planning, scheduling, and fault diagnosis of complex systems. There are, however, many aspects of system and subsystem design in an autonomous system that impact AI applications, but do not directly involve AI technology. Development of a system control architecture, establishment of an operating system within the design, providing command and sensory data collection features appropriate to automated operation, and the use of design analysis tools to support system engineering are specific examples of major design issues. Aspects such as these must also receive attention and technology development support if we are to implement complex autonomous systems within the realistic limitations of mass, power, cost, and available flight-qualified technology that are all-important to a flight project.

    Informed consent is the practical expression of the doctrine of autonomy. But the very idea of autonomy and conscious free choice is undercut by the view that human beings react as their unconscious brain centres dictate, depending on factors that may or may not be under rational control and reflection. This worry is, however, based on a faulty model of human autonomy and consciousness and needs close neurophilosophical scrutiny. A critique of the ethics implied by the model takes us towards a 'care of the self' view of autonomy and the subject's attunement to the truth as the crux of reasoning rather than the inner mental/neural state views of autonomy and human choice on offer at present.

    This book challenges traditional approach to university autonomy which is based on four pillars: organisational, financial, human resource, and academic. The main thesis is that a fuller understanding of university autonomy can only be obtained through a more holistic view of the complex inter......-relationships between stakeholders and policies which can reinforce and equally pull in opposite directions. The holistic view is expressed in a model of institutional university autonomy that brings together the traditional basic four pillars of autonomy, and five interfaces: government–university; university......–university staff; academic staff–students; university–business; and university–internationalisation. This model is explored through international case studies that give new insights and reinforce our understanding that the issues relating to institutional university autonomy are complex, interactive and genuinely...

  5. Neuromodulation, agency and autonomy.

    Glannon, Walter

    2014-01-01

    Neuromodulation consists in altering brain activity to restore mental and physical functions in individuals with neuropsychiatric disorders and brain and spinal cord injuries. This can be achieved by delivering electrical stimulation that excites or inhibits neural tissue, by using electrical signals in the brain to move computer cursors or robotic arms, or by displaying brain activity to subjects who regulate that activity by their own responses to it. As enabling prostheses, deep-brain stimulation and brain-computer interfaces (BCIs) are forms of extended embodiment that become integrated into the individual's conception of himself as an autonomous agent. In BCIs and neurofeedback, the success or failure of the techniques depends on the interaction between the learner and the trainer. The restoration of agency and autonomy through neuromodulation thus involves neurophysiological, psychological and social factors.

    Full Text Available The living environment must not only meet the primary needs of living, but also the expectations of improvement of life and social relations and people’s work. The need for a living environment that responds to the needs of users with their different abilities, outside of standardizations, is increasingly felt as autonomy, independence and well-being are the result of real usability and adaptability of the spaces. The project to improve the inclusivity of living space and to promote the rehabilitation of fragile users need to be characterized as an interdisciplinary process in which the integration of specialized contributions leads to adaptive customization of space solutions and technological that evolve with the changing needs, functional capacities and abilities of individuals.

    2013-11-21

    A nucleic acid thermal cycler is considered to be portable if it is under ten pounds, easily carried by one individual, and battery powered. Nucleic acid amplification includes both polymerase chain reaction (e.g. PCR, RT-PCR) and isothermal amplification (e.g. RPA, HDA, LAMP, NASBA, RCA, ICAN, SMART, SDA). There are valuable applications for portable nucleic acid thermocyclers in fields that include clinical diagnostics, biothreat detection, and veterinary testing. A system that is portable allows for the distributed detection of targets at the point of care and a reduction of the time from sample to answer. The designer of a portable nucleic acid thermocycler must carefully consider both thermal control and the detection of amplification. In addition to thermal control and detection, the designer may consider the integration of a sample preparation subsystem with the nucleic acid thermocycler. There are a variety of technologies that can achieve accurate thermal control and the detection of nucleic acid amplification. Important evaluation criteria for each technology include maturity, power requirements, cost, sensitivity, speed, and manufacturability. Ultimately the needs of a particular market will lead to user requirements that drive the decision between available technologies.

    The advent of antiproton research utilizing relatively small scale storage devices for very large numbers of these particles opens the possibility of transporting these devices to a research site removed from the accelerator center that produced the antiprotons. Such a portable source of antiprotons could open many new areas of research and make antiprotons available to a new research community. At present antiprotons are available at energies down to 1 MeV. From a portable source these particles can be made available at energies ranging from several tens of kilovolts down to a few millielectron volts. These low energies are in the domain of interest to the atomic and condensed matter physicist. In addition such a source can be used as an injector for an accelerator which could increase the energy domain even further. Moreover, the availability of such a source at a university will open research with antiprotons to a broader range of students than possible at a centralized research facility. This report focuses on the use of ion traps, in particular cylindrical traps, for the antiproton storage device. These devices store the charged antiprotons in a combination of electric and magnet fields. At high enough density and low enough temperature the charged cloud will be susceptible to plasma instabilities. Present day ion trap work is just starting to explore this domain. Our assessment of feasibility is based on what could be done with present day technology and what future technology could achieve. We conclude our report with a radiation safety study that shows that about 10 11 antiprotons can be transported safely, however the federal guidelines for this transport must be reviewed in detail. More antiprotons than this will require special transportation arrangements. 28 refs., 8 figs

    Fuel cells were originally intended for use in power plants and vehicles. More recently, developers realised the possibility for building much smaller units and for lower prices per kilowatt than their larger relatives. This has led to a strong interest in developing small fuel cells. Small fuel cells could replace batteries in portable electronic equipment and internal combustion engines in portable generators. The upper limit for portable generators is about 5kW, mainly because of the weight of the fuel cell. The main applications for low-power fuel cells are mobile phones, personal digital assistants, laptop and notebook computers, cameras, medical equipment, military applications and other portable electronic devices. In comparison to batteries, fuel cells can supply much more power per unit volume or weight, though they have lower output voltages and are slower to respond to transients. Fuel cell types that are suitable for portable applications include: proton exchange membrane fuel cells (PEMFCs) using pure hydrogen, PEMFCs using hydrogen-rich gases from hydrocarbon or alcohol reforming, direct methanol fuel cells and, high-temperature fuel cells such as solid oxide fuel cells (SOFCs) and molten carbonate fuel cells (MCFCs) using hydrocarbons directly. Fuel cells for portable devices is becoming a niche, high-value market area which has good opportunities for a fast introduction of fuel cell technology and for the first consumer products in the electronic market can be expected within the coming year and is believed to grow rapidly thereafter. Danish industry is involved in the development of SOFC, PEMFC and DMFC fuel cells and the industry has in particular a strong position in system components and complete systems. An important area for Danish industry is system integration, where fuel cells and hydrogen technologies are implemented in electrical powered products.

    The article reveals how university autonomy may in practice prove to be restrictive for units within the university. The need to implement and interpret external regulations and protect the institution may, argued in the paper, lead to a risk averse, conservative approach which is experienced...... by departments as bureaucratic and hampering effective research. Thus autonomy has produced new internal tensions between the central management/administration and the departments which it is argued is counter-productive and not beneficial for research and could be seen as a perverse aspect of greater autonomy....... Indeed because university policy and ‘interference’ is much closer to the researcher than in former less autonomous times and the university may now exercise other direct incentives through resource allocation, promotion and salary enhancement, the department and the individual may view autonomy...

  18. Learning for autonomy

    There is a need for a new concept of post-literacy which goes beyond the learning of codes. The target population is defined on the basis of their need to be given the capacity to take decisions on essential economic, civic, political and day-to-day aspects of their lives. The main arena of post-literacy lies in the countries of the Third World, where the economic crisis has serious effects on the quality of life and impairs the motivation to learn. Particular reference is made to the concept of participation and to the ability to determine four types of basic educational need: fundamental needs, productivity needs, social service needs and community organization needs. Four Latin American programmes linked to these four types of need are presented and discussed in terms of their particular features: popular participation in decision making; the search for methods and techniques which give the population a certain degree of autonomy; and respect for the cultures and world visions of the communities in the conduct of post-literacy, educational innovation and other activities. The programmes are: post-literacy in Nicaragua (fundamental education needs); research on post-literacy and employment in 13 countries (productivity needs); the CIPCA project for peasants in Piura, on the northern coast of Peru (social service needs); and the `Talking Maps' project developed with the Paez community in Cauca, Colombia (community organization needs).

    An electronics package for a small, battery-operated, self-contained, neutron coincidence counter based on a portable shift-register (PSR) has been developed. The counter was developed for applications not adequately addressed by commercial packages, including in-plant measurements to demonstrate compliance with regulations (domestic and international), in-plant process control, and in-field measurements (environmental monitoring or safeguards). Our package's features, which address these applications, include the following: Small size for portability and ease of installation;battery or mains operation; a built-in battery to power the unit and a typical detector such as a small sample counter, for over 6 h if power lines are bad or noisy, if there is a temporary absence of power, or if portability is desired; complete support, including bias, for standard neutron detectors; a powerful communications package to easily facilitate robust external control over a serial port; and a C-library to simplify creating external control programs in computers or other controllers. Whereas the PSR specifically addresses the applications mentioned above, it also performs all the measurements made by previous electronics packages for neutron coincidence counters developed at Los Alamos and commercialized. The PSR electronics package, exclusive of carrying handle, is 8 by 10 by 20 cm; it contains the circuit boards, battery, and bias supply and weighs less than 2 kg. This instrument package is the second in an emerging family of portable measurement instruments being developed; the first was the Miniature and Modular Multichannel Analyzer (M 3 CA). The PSR makes extensive use of hardware and software developed for the M 3 CA; like the M 3 CA, it is intended primarily for use with an external controller interfaced over a serial channel

    This factsheet is intended to help consumers select a small portable generator for emergency electrical needs. Interest in standby generators has been heightened ever since the prolonged power outage in Eastern Ontario and Southwestern Quebec during the 1998 ice storm and the concern over Y2K related outages. Farmers, in particular, have been reassessing their need for emergency electrical power supply. This document presents some of the factors that should be considered when purchasing and operating a portable generator in the 3 to 12 kW size. It provides a detailed review of power quality and describes the use of tractor-driven power-take-off generators of 15 kW and larger. Several manufacturers make portable generators in many sizes with a whole range of features. This document includes a table depicting generator Feature/Benefit analysis to help consumers understand the differences between features and benefits. A second table provides a check list for generator feature/benefits. Specific details for the operations of various generators are available from manufacturers, distributors and electrical contractors. 2 tabs., 1 fig.

    1994-01-01

    Objective was to develop a field-portable monitor for sensitive hazardous waste detection using active nitrogen energy transfer (ANET) excitation of atomic and molecular fluorescence (active nitrogen is made in a dielectric-barrier discharge in nitrogen). It should provide rapid field screening of hazardous waste sites to map areas of greatest contamination. Results indicate that ANET is very sensitive for monitoring heavy metals (Hg, Se) and hydrocarbons; furthermore, chlorinated hydrocarbons can be distinguished from nonchlorinated ones. Sensitivity is at ppB levels for sampling in air. ANET appears ideal for on-line monitoring of toxic heavy metal levels at building sites, hazardous waste land fills, in combustor flues, and of chlorinated hydrocarbon levels at building sites and hazardous waste dumps

  11. Models, controls, and levels of semiotic autonomy

    Energy Technology Data Exchange (ETDEWEB)

    Joslyn, C.

    1998-12-01

    In this paper the authors consider forms of autonomy, forms of semiotic systems, and any necessary relations among them. Levels of autonomy are identified as levels of system identity, from adiabatic closure to disintegration. Forms of autonomy or closure in systems are also recognized, including physical, dynamical, functional, and semiotic. Models and controls are canonical linear and circular (closed) semiotic relations respectively. They conclude that only at higher levels of autonomy do semiotic properties become necessary. In particular, all control systems display at least a minimal degree of semiotic autonomy; and all systems with sufficiently interesting functional autonomy are semiotically related to their environments.

    Impending energy shortage and distribution conflicts have stimulated the discussion concerning natural energy sources in Germany. The conflicts indicate the dependence of the German industry on imported raw materials. Supply shortages show the vulnerability of central supply structures. This conference, held by EnergieAgentur.NRW in cooperation with Technische Akademie Wuppertal (TAW) on 16 November 2006, addressed industrial organisations, communities and utilities in an attempt to show how organisations may become independent by constructing their own power plants, and in what cases such solutions are acceptable and economically useful. The conference focused on projects in the planning and production stage, e.g. an office building at Aachen, the Gelsenkirchen Marienhospital building, the common power station projected by several municipal utilities in the Ruhr region, and the 100 MW refuse-fuelled power station of Norddeutsche Affinerie AG Hamburg, which was presented by Dr. Werner Marnette, chairman of the board and managing director of Europe's biggest producer of copper.

    2017-10-01

    Full Text Available Some elements of the ideal of moral autonomy are discussed in this paper. Such ideal is a key assumption in social practices focused on normative imputation, particularly morality and law. First, a constructivist conception of normativity is introduced, taking reasons as an essential and non-reducible element, and focused on the conceptual features of moral reasons within the normative domain. Then, an idea of moral autonomy based on the self-constitution is developed including three key features: the possibility of responding to reasons based on shared social expectations; the responsibility for certain scope of actions, according to a set of reasons available to the individual and to their maximum extent of expansion; and the need to preserve autonomy as a purpose unifying the set of autonomous actions of moral agents.

    Portable meters were discussed as alternatives to standard billing meters for temporary installations. Current, voltage and power factor at a distribution station were measured to calculate kW and kVAR, using an easy to install product that communicates live readings directly to the existing billing system. A background of situations where temporary metering is a possible alternative to regular meters was presented. Use of electronic, clamp on Electronic Recording Ammeters (ERA) and their drawbacks were discussed. An improved temporary metering solution using FM radio transmission to deliver live data to a receiving device, the Eagle Series 3500, was introduced. Improvements over previous ERA systems were discussed, including accuracy, lack of batteries, immediate confirmation of functionality, current, voltage and power factor monitoring, direct feed to billing system, line crew savings, need for only a single unit at any given site, bi-directional power flow metering, independent report storage media, and a portable voltage and P.F. diagnostic tool. Details of trial applications at the Utopia distribution station west of Barrie, ON were presented. This technology was said to be still in the testing stage, but its flexibility and economy were sonsidered to be very promising for future application.

  15. Mental health as rational autonomy.

    Science.gov (United States)

    Edwards, R B

    1981-08-01

    Rather than eliminate the terms "mental health and illness" because of the grave moral consequences of psychiatric labeling, conservative definitions are proposed and defended. Mental health is rational autonomy, and mental illness is the sustained loss of such. Key terms are explained, advantages are explored, and alternative concepts are criticized. The value and descriptive components of all such definitions are consciously acknowledged. Where rational autonomy is intact, mental hospitals and psychotherapists should not think of themselves as treating an illness. Instead, they are functioning as applied axiologists, moral educators, spiritual mentors, etc. They deal with what Szasz has called "personal, social, and ethical problems in living." But mental illness is real.

    2016-07-01

    Full Text Available Portable polymer electrolyte membrane (PEM fuel cell power generator is a PEM fuel cell application that is used as an external charger to supply the demand for high energy. Different environments at various ambient temperatures and humidity levels affect the performance of PEM fuel cell power generators. Thermal and water management in portable PEM fuel cells are a critical technical barrier for the commercialization of this technology. The size and weight of the portable PEM fuel cells used for thermal and water management systems that determine the performance of portable PEM fuel cells also need to be considered. The main objective of this paper review was to determine the importance of water and thermal management systems in portable PEM fuel cells. Additionally, this review investigated heat transfer and water transport in PEM fuel cells. Given that portable PEM fuel cells with different powers require different thermal and water management systems, this review also discussed and compared management systems for low-, medium-, and high-power portable PEM fuel cells.

    The NZG 201 spectrometric unit is a portable single-channel processing unit supplied from the mains or a battery which allows the qualitative and quantitative measurement of different types of ionizing radiation when connected to a suitable detection unit. The circuit layout and the choice of control elements makes the spectrometric unit suitable for use with scintillation detector units. The spectrometric unit consists of a pulse amplifier, an amplitude pulse analyzer, a pulse counter, a pulse rate counter with an output for a recorder, a high voltage source and a low voltage source. The block diagram is given. All circuits are modular and are mounted on PCB's. The apparatus is built in a steel cabinet with a raised edge which protects the control elements. The linear pulse amplifier has a maximum gain of 1024, the pulse counter has a maximum capacity of 10 6 -1 imp and time resolution better than 0.5 μs. The temperature interval at which the apparatus is operational is 0 to 45 degC, its weight is 12.5 kg and dimensions 36x280x310 mm, energy range O.025 to 2.5 MeV, for 137 Cs the energy resolution is 8 to 10%. The spectrometric unit NZG 2O1 may, with regard to its parameters, number and range of control elements, be used as a universal measuring unit. (J.P.)

    2008-07-01

    With the introduction of a cost recovering energy feeding law, new possibilities open up for the building integration of photovoltaics and for the solar power generation at the ''Point of sale ''. Still, the appropriate Swiss market is marginal. Not all legal, technical and financial hurdles are removed. Here the photovoltaics with its building integration is in touch with an emotional factor of revaluation: An integration of photovoltaics adresses the building owner beyond their technical-economic value at a culturally abstract level - a wing of a butterfly oscillating in the sunlight also touches on a completely different level. Exactly the same the integration of photovoltaics makes the building to a unique piece of jewellery. In the pioneer phase of the photovoltaics market, architectonically successful integrations of photovoltaics succeeded in a break-through of the solar power generation. Photovoltaics at building coverings is more than a ''fashion '': it becomes a lever arm, with which the solarization of our society transports significant values. Apart from rational-technical considerations this effect has to be used to favour a broad application of photovoltaics with the building integration more purposefully.

    This PhD project investigates hardware strategies and imaging methods for hand-held ultrasound systems. The overall idea is to use a wireless ultrasound probe linked to general-purpose mobile devices for the processing and visualization. The approach has the potential to reduce the upfront costs...... beamforming strategies are simulated from a system-level perspective. The quality of the B-mode image is evaluated and the minimum specifications are derived for the design of a portable probe with integrated electronics in-handle. The system is based on a synthetic aperture sequential beamforming approach...... that allows to significantly reduce the data rate between the probe and processing unit. The second part investigates the feasibility of vector flow imaging in a hand-held ultrasound system. Vector flow imaging overcomes the limitations of conventional imaging methods in terms of flow angle compensation...

  9. Public Health Autonomy: A Critical Reappraisal.

    Science.gov (United States)

    Zimmerman, Frederick J

    2017-11-01

    The ethical principle of autonomy is among the most fundamental in ethics, and it is particularly salient for those in public health, who must constantly balance the desire to improve health outcomes by changing behavior with respect for individual freedom. Although there are some areas in which there is a genuine tension between public health and autonomy-childhood vaccine mandates, for example-there are many more areas where not only is there no tension, but public health and autonomy come down to the same thing. These areas of overlap are often rendered invisible by a thin understanding of autonomy. Better integrating newer theoretical insights about autonomy into applied ethics can make discussions of public health ethics more rigorous, incisive, and effective. Even more importantly, bringing modern concepts of autonomy into public health ethics can showcase the many areas in which public health and autonomy have the same goals, face the same threats, and can be mutually advanced by the same kinds of solutions. This article provides a schema for relational autonomy in a public health context and gives concrete examples of how autonomy can be served through public-health interventions. It marshals insights from sociology, psychology, and philosophy to advance a theory of autonomy and coercion that recognizes three potential threats to autonomy: threats to choice sets, threats to knowledge, and threats to preferences. © 2017 The Hastings Center.

    2009-03-01

    Two studies examined the hypothesis that relative to control motivation, autonomy motivation is associated with effective written expression and regulation, leading to positive emotional, physical, and cognitive outcomes over time. Participants viewed a Hiroshima-Nagasaki documentary in each of two sessions. Study 1 showed that dispositionally autonomous participants, particularly those who expressed, had positive well-being, energy, and memory after the second viewing. Study 2 explored benefits of situational motivation by priming autonomy and control. Results showed that dispositionally controlled individuals received the same benefits as autonomous individuals only when primed with autonomy and encouraged to express. Coding of writing content revealed that the benefits of autonomy were mediated by nondefensive and effective emotional processing, as reflected in greater use of self-referencing and cognitive mechanism words and lower use of concrete words. Results support the expectation that autonomy relates to effective expression and emotion regulation, leading to positive functioning over time.

  12. Enhancing autonomy in paid surrogacy.

    Damelio, Jennifer; Sorensen, Kelly

    2008-06-01

    The gestational surrogate--and her economic and educational vulnerability in particular--is the focus of many of the most persistent worries about paid surrogacy. Those who employ her, and those who broker and organize her services, usually have an advantage over her in resources and information. That asymmetry exposes her to the possibility of exploitation and abuse. Accordingly, some argue for banning paid surrogacy. Others defend legal permission on grounds of surrogate autonomy, but often retain concerns about the surrogate. In response to the dilemma of a ban versus bald permission, we propose a 'soft law' approach: states should require several hours of education of surrogates--education aimed at informing and enhancing surrogate autonomy.

    Full Text Available In this paper, it is argued that both the informer and the hearer in a testimonial situation deserve epistemic merit insofar as they contribute to the collaborative achievement of sharing knowledge. The paper introduces a distinction between the ideals of self-sufficiency and epistemic autonomy. The autonomous exercise of our epistemic agency is very often carried out under strong conditions of epistemic dependence. Testimony exhibits a kind of social dependence that does not threaten the autonomy of the subjects that need to consider their own epistemic capacities. When involved in a testimonial situation, both speaker and hearer declare, at least implicitly, the standings they occupy in an epistemic space and are obliged to recognise certain epistemic requirements.

    1993-01-01

    I argue that the distinction which is current in much writing on medical ethics between autonomous and non-autonomous patients cannot cope comfortably with weak-willed (incontinent) patients. I describe a case involving a patient who refuses a blood transfusion even though he or she agrees that it would be in his or her best interests. The case is discussed in the light of the treatment of autonomy by B Brody and R Gillon. These writers appear to force us to treat an incontinent patient either as autonomous, just like a rational agent whose decisions are in accordance with his beliefs or as non-autonomous, like comatose patients or children. Though neither is entirely satisfactory I opt for describing such patients as autonomous but point out that in cases like this the principle of respect for autonomy does not give a determinate answer about how the patient ought to be treated.

  16. The many faces of autonomy.

    Science.gov (United States)

    Gracia, Diego

    2012-02-01

    What does autonomy mean from a moral point of view? Throughout Western history, autonomy has had no less than four different meanings. The first is political: the capacity of old cities and modern states to give themselves their own laws. The second is metaphysical, and was introduced by Kant in the second half of the 18th century. In this meaning, autonomy is understood as an intrinsic characteristic of all rational beings. Opposed to this is the legal meaning, in which actions are called autonomous when performed with due information and competency and without coercion. This last meaning, the most frequently used in bioethics, is primarily legal instead of moral. Is there a proper moral meaning of the word autonomy? If so, this would be a fourth meaning. Acts can only be called moral when they are postconventional (using the terminology coined by Lawrence Kohlberg), inner-directed (as expressed by David Riesman), and responsible (according to Hannah Arendt). Such acts are autonomous in this new, fourth, and to my mind, the only one proper, moral meaning. The goal of ethics cannot be other than forming human beings capable of making autonomous and responsible decisions, and doing so because they think this is their duty and not because of any other nonmoral motivation, like comfort, convenience, or satisfaction. The goal of ethics is to promote postconventional and mature human beings. This was what Socrates tried to do with the young people of Athens. And it is also the objective of every course of ethics and of any process of training.

    2015-01-01

    Wireless power transmission (WPT) technology can solve the energy shortage problem of the video capsule endoscope (VCE) powered by button batteries, but the fixed platform limited its clinical application. This paper presents a portable WPT system for VCE. Besides portability, power transfer efficiency and stability are considered as the main indexes of optimization design of the system, which consists of the transmitting coil structure, portable control box, operating frequency, magnetic core and winding of receiving coil. Upon the above principles, the correlation parameters are measured, compared and chosen. Finally, through experiments on the platform, the methods are tested and evaluated. In the gastrointestinal tract of small pig, the VCE is supplied with sufficient energy by the WPT system, and the energy conversion efficiency is 2.8%. The video obtained is clear with a resolution of 320×240 and a frame rate of 30 frames per second. The experiments verify the feasibility of design scheme, and further improvement direction is discussed.

    This paper presents a batteryless system-on-chip (SoC) that operates off energy harvested from indoor solar cells and/or thermoelectric generators (TEGs) on the body. Fabricated in a commercial 0.13 μW process, this SoC sensing platform consists of an integrated energy harvesting and power management unit (EH-PMU) with maximum power point tracking, multiple sensing modalities, programmable core and a low power microcontroller with several hardware accelerators to enable energy-efficient digital signal processing, ultra-low-power (ULP) asymmetric radios for wireless transmission, and a 100 nW wake-up radio. The EH-PMU achieves a peak end-to-end efficiency of 75% delivering power to a 100 μA load. In an example motion detection application, the SoC reads data from an accelerometer through SPI, processes it, and sends it over the radio. The SPI and digital processing consume only 2.27 μW, while the integrated radio consumes 4.18 μW when transmitting at 187.5 kbps for a total of 6.45 μW.

  2. Portable, accurate toxicity testing

    1994-01-01

    Ever tightening environmental regulations, severe penalties for non-compliance, and expensive remediation costs have stimulated development of methods to detect and measure toxins. Most of these methods are bioassays that must be performed in the laboratory; none previously devised has been truly portable. The US Army, through the Small Business Innovative Research program, has developed a hand-held, field deployable unit for testing toxicity of battlefield water supplies. This patented system employs the measurable quenching, in the presence of toxins, of the natural bioluminescence produced by the marine dinoflagellate alga Pyrocystis lunula. The procedure's inventor used it for years to measure toxicity concentrations of chemical warfare agents actually, their simulants, primarily in the form of pesticides and herbicides plus assorted toxic reagents, waterbottom samples, drilling fluids, even blood. While the procedure is more precise, cheaper, and faster than most bioassays, until recently it was immobile. Now it is deployable in the field. The laboratory apparatus has been proven to be sensitive to toxins in concentrations as low as a few parts per billion, repeatable within a variation of 10% or less, and unlike some other bioassays effective in turbid or colored media. The laboratory apparatus and the hand-held tester have been calibrated with the EPA protocol that uses the shrimplike Mysidopsis bahia. The test organism tolerates transportation well, but must be rested a few hours at the test site for regeneration of its light-producing powers. Toxicity now can be measured confidently in soils, water columns, discharge points, and many other media in situ. Most significant to the oil industry is that drilling fluids can be monitored continuously on the rig

    Visualization of scientific data although a fashionable word in the world of computer graphics, is not a new invention, but it is hundreds years old. With the advent of computer graphics the visualization of Scientific Data has now become a well understood and widely used technology, with hundreds of applications in the most different fields, ranging from media applications to real scientific ones. In the present paper, we shall discuss the design concepts of the Visualization of Scientific Data systems in particular in the specific field of High Energy Physics. During the last twenty years, CERN has played a leading role as the focus for development of packages and software libraries to solve problems related to High Energy Physics (HEP). The results of the integration of resources from many different Laboratories can be expressed in several million lines of code written at CERN during this period of time, used at CERN and distributed to collaborating laboratories. Nowadays, this role of software developer is considered very important by the entire HEP community. In this paper a large software package, where man-machine interaction and graphics play a key role (PAW-Physics Analysis Workstation), is described. PAW is essentially an interactive system which includes many different software tools, strongly oriented towards data analysis and data presentation. Some of these tools have been available in different forms and with different human interfaces for several years. 6 figs

    2016-12-01

    In workplace settings, autonomy is implicated in employee motivation as well as supervisor autonomy support. As a profession of risk, firefighters may experience greater levels of stress. A self-determination paradigm was applied to the firefighter workplace. Of particular interest were perceived competence (to perform job duties) and the experience of stress. Firefighters' levels of autonomous and controlled regulation were surveyed, along with their perceptions of the autonomy support of their immediate supervisor. Autonomous regulation was positively related to perceived competence, whereas controlled regulation was negatively related. Higher levels of controlled regulation were also connected with greater stress. In contrast, greater perceived autonomy support was associated with decreased stress. Both perceived competence and stress are related to firefighter motivation and autonomy support. Recommendations are offered to increase autonomy support by chief officers.

    Contemporary political liberals argue for extending the scope of reasonable disagreement to include also the principle of autonomy that was central in classical liberal theory. I take outset in Charles Larmore, The Autonomy of Morality (2008), which argues that liberal theory can dispense...... with the commitment to autonomy that one finds in Locke, Kant, and Mill, because "the essential convictions of liberal thought lie at a more fundamental level," namely in the principle of respect for persons. The main question I address is whether we can see the commitment to respect for persons as separable from...... the commitment to autonomy. My focus is the Kantian conception of autonomy, and I argue for understanding this conception practically and politically, rather than metaphysically and theoretically. In this way we can separate the principle of respect for persons from the metaphysical idea of autonomy as self...

  8. From solidarity to autonomy: towards a redefinition of the parameters of the notion of autonomy.

    Science.gov (United States)

    Fainzang, Sylvie

    2016-12-01

    Starting from examples of concrete situations in France, I show that autonomy and solidarity can coexist only if the parameters of autonomy are redefined. I show on the one hand that in situations where autonomy is encouraged, solidarity nevertheless remains at the foundation of their practices. On the other hand, in situations largely infused with family solidarity, the individual autonomy may be put in danger. Yet, based on my ethnographic observations regarding clinical encounters and medical secrecy, I show that while solidarity may endanger individual autonomy, it does not necessarily endanger autonomy itself. The social practices observable in France reflect the reality of an autonomy that goes beyond the individual, a reality that involves a collective subject and includes solidarity. The opposition between these two values can then be resolved if the content of the notion of autonomy is understood to be dependent on its cultural context of application and on its social use.

    2017-12-01

    In a project The Hastings Center is now running on the future of prenatal testing, we are encountering clear examples, both in established law and in the practices of individual providers, of failures to respect women's reproductive autonomy: when testing is not offered to certain demographics of women, for instance, or when the choices of women to terminate or continue pregnancies are prohibited or otherwise not supported. But this project also raises puzzles for reproductive autonomy. We have learned that some clinicians and patients do not discuss the fact that prenatal testing can lead to a decision about whether to terminate a pregnancy-they just don't talk about it. And while the decision whether to agree to prenatal screening and diagnostic testing is to be made with women's free and informed consent, many screening tests have been routinized in such a way that some women do not even recall agreeing to testing, while others feel that agreeing to testing is what their clinicians expect of them or that the testing is necessary to protect themselves and their families from the significant financial hardship of raising a child with a disability. In the face of these pressures, can one really say that women are freely choosing to undergo testing or are freely choosing to continue or terminate a pregnancy following receipt of test results? The reality of these pressures is requiring us to consider expanding the scope of our investigation beyond the clinical encounter to the broader context-to think harder about what reproductive autonomy means and how best to enhance it. © 2017 The Hastings Center.

    2012-01-01

    Full Text Available Autonomy takes many shapes. The concept of “graduated autonomy” is conceived as comprising several unique features: (1 it is incremental, (2 it is proportional, and (3 it is related to the telos of the life stage during which it occurs. This paper focuses on graduated autonomy in the context of genetic testing during adolescence. Questions can be raised about other life stages as well, and some of these questions will be addressed by discussing a possible fourth characteristic of graduated autonomy, that is, its elasticity. Further scholarship and analysis is needed to refine the concept of graduated autonomy and examine its applications.

Data derived from a survey of 381 MNC subsidiaries located in Denmark, Germany and the UK demonstrate that low-autonomy subsidiaries are highly embedded in their respective MNC networks and that they establish ...... relationship between lower autonomy and the production activities carried out by the subsidiary. In fact, low-autonomy subsidiaries appear to be specialized in that they focus on a few value-chain activities and they typically serve as marketing outlets....

  12. An intercultural nursing perspective on autonomy.

    Science.gov (United States)

    Hanssen, Ingrid

    2004-01-01

    This article is based on an empirical study regarding ethical challenges in intercultural nursing. The focus is on autonomy and disclosure. Autonomy is a human capacity that has become an important ethical principle in nursing. Although the relationship between autonomy and patients' possibly harmful choices is discussed, the focus is on 'forced' autonomy. Nurses seem to equate respect with autonomy; it seems to be hard to cope with the fact that there are patients who voluntarily undergo treatment but who actively participate neither in the treatment offered nor in making choices regarding that treatment. Nurses' demand for patients to be autonomous may in some cases jeopardize the respect, integrity and human worth that the ethical principle of autonomy is meant to ensure. Even though respect for a person's autonomy is also respect for the person, one's respect for the person in question should not depend on his or her capacity or aptitude to act autonomously. Is autonomy necessarily a universal ethical principle? This article negates this question and, through the issues of culture, individualism versus collectivism, first- and second-order autonomy, communication and the use of family interpreters, and respect, an attempt is made to explain why.

  13. Professional Autonomy versus Corporate Control

    2012-06-01

    Full Text Available Professionalism and bureaucracy tend to be understood as incompatible systems of work organization, represented by the ideals of collegiality and auton-omy versus control and supervision. I present a historical case study from early 20th century Norway examining the potential clash between efforts made toward professionalization and bureaucratization in industry. Based on my findings, I argue that there is neither an inherent conflict between professionalism and bureaucracy nor static national trajectories at the level of professional versus bureaucratic work organization.

  20. Agency is Distinct from Autonomy

    Directory of Open Access Journals (Sweden)

    Fred Cummins

    2014-11-01

    Full Text Available Both autonomy and agency play central roles in the emerging enactive vocabulary. Although some treat these concepts as practically synonymous, others have sought to be more explicit about the conditions required for agency over and above autonomy. I attempt to be self-conscious about the role of the observer (or scientist in such discussions, and emphasise that the concept of agency, in particular, is deeply entwined with the nature of the observer and the framing of the observation. This is probably well known to enactivists, but runs the risk of being badly misunderstood if it is not made explicit. A heightened awareness of the role of the observer in the attribution of agency may allow us to make advances in questions in which progress is hindered by assuming a single split between subject and object. I argue that human experience is characterized by our embedding in webs of meaning arising from our participation in systems of many sorts, and that this richness demands a corresponding lightness of touch with respect to the identification of agentive subjects.

  11. Progress in medicine: autonomy, oughtonomy and nudging.

    Science.gov (United States)

    Devisch, Ignaas

    2011-10-01

    In this article, I argue that we need a new perspective in the debate on autonomy in medicine, to understand many of the problems we face today - dilemmas that are situated at the intersection of autonomy and heteronomy, such as why well informed and autonomous people make unhealthy lifestyle choices. If people do not choose what they want, this is not simply caused by their lack of character or capability, but also by the fact that absolute autonomy is impossible; autonomous individuals are 'contaminated' by heteronymous aspects, by influences from 'outside'. Consequently, there are many good reasons to question the widely accepted hierarchical opposition of autonomy (progress) versus heteronomy (paternalism) in medicine. In an earlier article an analysis is made of the neologism 'oughtonomy' to support the thesis that when it comes down to human existence, autonomy and heteronomy are intertwined, rather than being merely opposites. In this article, I reflect upon how social conditions might improve our 'choice architecture', what Thaler & Sunstein have called 'nudging': how to change individual health choices without being paternalistic? I explore the extent to which both oughtonomy and nudging are able to challenge the question of autonomy in today's medicine. Autonomy may and should be a shared target in today's medicine, but we should never forget that it is always intertwined with heteronomy. Starting from this perspective, progress in medicine demands far more than the increase of autonomy. © 2011 Blackwell Publishing Ltd.

  13. Protecting autonomy as authenticity using Ulysses contracts.

    Science.gov (United States)

    van Willigenburg, Theo; Delaere, Patrick

    2005-08-01

    Pre-commitment directives or Ulysses contracts are often defended as instruments that may strengthen the autonomous self-control of episodically disordered psychiatric patients. Autonomy is understood in this context in terms of sovereignty ("governing" or "managing" oneself). After critically analyzing this idea of autonomy in the context of various forms of self-commitment and pre-commitment, we argue that what is at stake in using Ulysses contracts in psychiatry is not autonomy as sovereignty, but autonomy as authenticity. Pre-commitment directives do not function to protect autonomous self-control. They serve in upholding the guidance that is provided by one's deepest identity conferring concerns. We elucidate this concept of autonomy as authenticity, by showing how Ulysses contracts protect the possibility of being "a self."

  14. Autonomy and independence in language learning

    CERN Document Server

    Benson, Phil

    2014-01-01

    The topics of autonomy and independence play an increasingly important role in language education. They raise issues such as learners' responsibility for their own learning, and their right to determine the direction of their own learning, the skills which can be learned and applied in self-directed learning and capacity for independent learning and the extents to which this can be suppressed by institutional education. This volume offers new insights into the principles of autonomy and independence and the practices associated with them focusing on the area of EFL teaching. The editors' introduction provides the context and outlines the main issues involved in autonomy and independence. Later chapters discuss the social and political implications of autonomy and independence and their effects on educational structures. The consequences for the design of learner-centred materials and methods is discussed, together with an exploration of the practical ways of implementing autonomy and independence in language ...

  15. Indications for treatment of thyroid autonomy

    International Nuclear Information System (INIS)

    Emrich, D.

    1989-01-01

    Based on pathophysiological findings and considerations it is attempted to review critically the present state of indications and therapeutic modalities in cases of thyroid autonomy. If hyperthyroidism occurs or has occurred in autonomy, definitive treatment with radioiodine or surgery is indicated. In cases of autonomy with euthyroidism, treatment planning and indication of definite therapy are difficult still today, because the risk to develop hyperthyroidism cannot as yet be sufficiently estimated. A useful indicator in such cases seems to be the percentage of global thyreoidal uptake of 99m-technetium under supression. If autonomy is severe surgical treatment today is superior to radio-iodine therapy, but is associated with a higher rate of manifest hypothyroidism. Further research into both the risk of hyperthyroidism in thyroid autonomy and the optimization of radio-iodine therapy are needed. (orig./MG) [de

  16. Integrated System Health Management (ISHM) and Autonomy

    Science.gov (United States)

    Figueroa, Fernando; Walker, Mark G.

    2018-01-01

    Systems capabilities on ISHM (Integrated System Health Management) and autonomy have traditionally been addressed separately. This means that ISHM functions, such as anomaly detection, diagnostics, prognostics, and comprehensive system awareness have not been considered traditionally in the context of autonomy functions such as planning, scheduling, and mission execution. One key reason is that although they address systems capabilities, both ISHM and autonomy have traditionally individually been approached as independent strategies and models for analysis. Additionally, to some degree, a unified paradigm for ISHM and autonomy has been difficult to implement due to limitations of hardware and software. This paper explores a unified treatment of ISHM and autonomy in the context of distributed hierarchical autonomous operations.

    Gordillo Alvarez-Valdés, Lourdes

    2008-01-01

    This paper considers the conditions of autonomy if this is to be the foundation of human dignity. Since Kant Modernity has dissociated nature from morality and has tried to support autonomy in its purely formal aspect. To forget nature has voluntarist consequences that affect the way in which autonomy is understand. But autonomy does not consist of not having links, but of knowing how to assume one's own links freely and to be conscious of one's own limits. Autonomy and liberty are the very thing of the rational being, capable of discerning good and bad, and this must direct our actions. Reason directs as and distances us from reality to recognize the advisable thing in the human being.

  9. Are the benefits of autonomy satisfaction and the costs of autonomy frustration dependent on individuals' autonomy strength?

    Science.gov (United States)

    Van Assche, Jasper; van der Kaap-Deeder, Jolene; Audenaert, Elien; De Schryver, Maarten; Vansteenkiste, Maarten

    2018-01-29

    From a self-determination theory perspective, individuals are assumed to benefit and suffer from, respectively, the satisfaction and frustration of the psychological need for autonomy, even if they score low on autonomy strength. Yet, previous studies on need strength are scarce, operationalized need strength differently, and produced inconsistent findings. In two studies among 224 South African adults (M age  = 24.13, SD = 4.25; 54.0% male) and 156 Belgian prisoners (M age  = 38.60, SD = 11.68; 88.5% male), we investigated the moderating role of autonomy valuation and desire in the relations of autonomy satisfaction and frustration with a variety of well-being and ill-being indicators. Study 1 provided some evidence for the moderating role of mostly explicit autonomy desire (rather than explicit autonomy valuation). In Study 2, neither explicit nor implicit autonomy desire played a consistent moderating role. Overall, these findings are congruent with a moderate (albeit not with a strong) interpretation of the universality claim made within self-determination theory, provide initial evidence for a differentiation between deficit-based and growth-oriented interpersonal differences in need strength, and indicate that the potential moderating role of need strength deserves continued attention before any firm conclusions can be drawn. © 2018 Wiley Periodicals, Inc.

    2014-07-01

    Full Text Available Solar is the intermittent source of renewable energy and all thermal solar systems having a setback on non-functioning during the night and cloudy environment. This paper presents alternative solution for power generation using thermoelectric which is the direct conversion of temperature gradient of hot side and cold side of thermoelectric material to electric voltage. Phase change material with latent heat effect would help to prolong the temperature gradient across thermoelectric material for power generation. Besides, the concept of portability will enable different power source like solar, wasted heat from air conditioner, refrigerator, stove etc, i.e. to create temperature different on thermoelectric material for power generation. Furthermore, thermoelectric will generate direct current which is used by all the gadgets like Smartphone, tablet, laptop etc. The portable concept of renewable energy will encourage the direct usage of renewable energy for portable gadgets. The working principle and design of portable thermoelectric power generator coupled with phase change material is presented in this paper.

The operating characteristics of the DMFC stack are applied to control the fuel ejection time and period, enabling the system to continue operating even when the MEAs of the stack are deteriorated. The portable system is also designed with several features including water balance and quick start-up (in 5 min). Notably, the proposed system using methanol sensor-less control with injection of pure methanol can power the DVD player and notebook PC. The system specific energy and energy density following three days of operation are 362 Wh kg{sup -1} and 335 Wh L{sup -1}, respectively, which are better than those of lithium batteries ({proportional_to}150 Wh kg{sup -1} and {proportional_to}250 Wh L{sup -}). This good energy storage feature demonstrates that the portable DMFC is likely to be valuable in computer, communication and consumer electronic (3C) markets. (author)

  15. Shared decision-making and patient autonomy.

    Sandman, Lars; Munthe, Christian

    2009-01-01

    In patient-centred care, shared decision-making is advocated as the preferred form of medical decision-making. Shared decision-making is supported with reference to patient autonomy without abandoning the patient or giving up the possibility of influencing how the patient is benefited. It is, however, not transparent how shared decision-making is related to autonomy and, in effect, what support autonomy can give shared decision-making. In the article, different forms of shared decision-making are analysed in relation to five different aspects of autonomy: (1) self-realisation; (2) preference satisfaction; (3) self-direction; (4) binary autonomy of the person; (5) gradual autonomy of the person. It is argued that both individually and jointly these aspects will support the models called shared rational deliberative patient choice and joint decision as the preferred versions from an autonomy perspective. Acknowledging that both of these models may fail, the professionally driven best interest compromise model is held out as a satisfactory second-best choice.

  16. Portable Radiation Package (PRP) Instrument Handbook

    2017-08-03

    The Portable Radiation Package (PRP) was developed to provide basic radiation information in locations such as ships at sea where proper exposure is remote and difficult, the platform is in motion, and azimuth alignment is not fixed. Development of the PRP began at Brookhaven National Laboratory (BNL) in the mid-1990s and versions of it were deployed on ships in the U.S. Department of Energy (DOE) Atmospheric Radiation Measurement (ARM) Climate Research Facility’s Nauru-99 project. The PRP was deployed on ships in support of the National Aeronautics and Space Administration (NASA) Sensor Intercomparison for Marine Biological and Interdisciplinary Ocean Studies (SIMBIOS) program. Over the years the measurements have remained the same while the post-processing data analysis, especially for the FRSR, has evolved. This document describes the next-generation Portable Radiation Package (PRP2) that was developed for the DOE ARM Facility, under contract no. 9F-31462 from Argonne National Laboratory (ANL). The PRP2 has the same scientific principles that were well validated in prior studies, but has upgraded electronic hardware. The PRP2 approach is completely modular, both in hardware and software. Each sensor input is treated as a separate serial stream into the data collection computer. In this way the operator has complete access to each component of the system for purposes of error checking, calibration, and maintenance. The resulting system is more reliable, easier to install in complex situations, and more amenable to upgrade.

  17. Markets & Myths: Autonomy in Public & Private Schools

    School choice is the most controversial education policy issue of the 1990s. John Chubb and Terry Moe's Politics, Markets and America's Schools stimulated this investigation. They concluded that teacher and administrator autonomy was the most important influence on student achievement. They assumed that the organization of private schools offered greater autonomy resulting in higher student achievement and that the bureaucracy of public schools stifles autonomy limiting student achievement. The research undertaken here elaborates, elucidates, and fills in the framework of teacher and principal autonomy in public and private secondary schools. Interviews of more than thirty teachers and administrators in six high schools, observations, field notes, and analysis of documents collected in the field form the empirical base of this work. The sites included three private, independent, nondenominational secondary schools which are college preparatory and three public secondary schools noted for high graduation rates and offering numerous advanced placement courses.

    The feelings expressed by both public and private school participants in this study testify to equally high degrees of autonomy. Issues that emerged from data analysis in this study which mitigate and shape autonomy include the following: conflicting and contradictory demands, shared beliefs, layers of protection, a system of laws, funding constraints and matters of size of the institution. These issues challenge oversimplified assertions that differences of any importance exist between the autonomy experienced by professionals in public and private high schools. This study reveals the complexity of the concept of autonomy and challenges the myth that teachers and principals in private schools enjoy autonomy and freedom from democratic bureaucracy that their public school counterparts do not.

    A topic of interest in contemporary museum studies is how digital technologies contribute to museum visitor experiences. Building on insights from media and technology studies that new media should be understood for how they overlap with old media, the article reports an ethnographic study...... of the intersections between the exhibition at a modern museum of natural history and three portable technologies – one of which is digital. Mobile phone cameras, exercise pamphlets and dress-up costumes link visitors with an exhibition, but they simultaneously shape this relation in their own specific directions....... This is shown by drawing on the concept of mediation as it is developed by philosopher Michel Serres and philosopher of technology Bruno Latour. The article is based on the Ph.D. thesis entitled “Portable Objects at the Museum”, defended at Roskilde University on 22 September 2010....

    We are beginning the second phase of a three and a half year program designed to develop a portable monitor for sensitive hazardous waste detection. The ultimate goal of the program is to develop our concept to the prototype instrument level. Our monitor will be a compact, portable instrument that will allow real-time, in situ, monitoring of hazardous wastes. This instrument will be able to provide the means for rapid field screening of hazardous waste sites to map the areas of greatest contamination. Remediation efforts can then focus on these areas. Further, our instrument can show whether cleanup technologies are successful at reducing hazardous materials concentrations below regulated levels, and will provide feedback to allow changes in remediation operations, if necessary, to enhance their efficacy.

  3. Development of portable flow calibrator

    1995-01-01

    In the nuclear facilities, air sniffer system is often utilized to evaluate atmospheric concentration of radioactivity in the working environment. The system collects airborne dust on the filter during some sampling period. In this method, total air flow during the sampling period is an important parameter to evaluate the radioactivity concentration correctly. Therefore, calibration for the flow meter of air sniffer system must be done periodically according to Japan Industry Standards (JIS). As we have had to available device to calibrate the flow meter in the working area, we had to remove the flow meters from the installed place and carry them to another place where calibration can be made. This work required a great deal of labor. Now we have developed a portable flow calibrator for air sniffer system which enables us to make in-site calibration of the flow meter in the working area more easily. This report describes the outline of portable flow calibrator and it's experimental results. (author)

    2008-07-15

    Telepathology is becoming easier to implement in most pathology departments. In fact e-mail image transmit can be done from almost any pathologist as a simplistic telepathology system. We tried to develop a way to improve capabilities of communication among pathologists with the idea that the system should be affordable for everybody. We took the premise that any pathology department would have microscopes and computers with Internet connection, and selected a few elements to convert them into a telepathology station. Needs were reduced to a camera to collect images, a universal microscope adapter for the camera, a device to connect the camera to the computer, and a software for the remote image transmit. We found out a microscope adapter (MaxView Plus) that allowed us connect almost any domestic digital camera to any microscope. The video out signal from the camera was sent to the computer through an Aver Media USB connector. At last, we selected a group of portable applications that were assembled into a USB memory device. Portable applications are computer programs that can be carried generally on USB flash drives, but also in any other portable device, and used on any (Windows) computer without installation. Besides, when unplugging the device, none of personal data is left behind. We selected open-source applications, and based the pathology image transmission to VLC Media Player due to its functionality as streaming server, portability and ease of use and configuration. Audio transmission was usually done through normal phone lines. We also employed alternative videoconferencing software, SightSpeed for bi-directional image transmission from microscopes, and conventional cameras allowing visual communication and also image transmit from gross pathology specimens. All these elements allowed us to install and use a telepathology system in a few minutes, fully prepared for real time image broadcast.

    2012-10-01

    Full Text Available The public healthcare system in South Africa is in need of urgent attention in no small part because there has been an escalation in the number of stroke victims which could be due to the increase in hypertension in this urbanizing society. There is a growing need for physiotherapists and occupational therapists in the country, which is further hindered by the division between urban and rural areas. A possible solution is a portable passive physiotherapeutic exoskeleton device. The exoskeleton device has been formulated to encapsulate methodologies that enable the anthropomorphic integration between a biological and mechatronic limb. A physiotherapeutic mechanism was designed to be portable and adjustable, without limiting the spherical motion and workspace of the human arm. The exoskeleton was designed to be portable in the sense that it could be transported geographically. It is a complete device allowing for motion in the shoulder, elbow, wrist and hand joints. The inverse kinematics was solved iteratively via the Damped Least Squares (DLS method. The electronic and computer system allowed for professional personnel to either change an individual joint or a combination of joints angles via the kinematic models. A ramp PI controller was established to provide a smooth response to simulate the passive therapy motion.

  8. How important is Autonomy to Professional Workers?

    Full Text Available A common assumption is that autonomy is crucial to professional workers. I examine this using survey data on a sample of public sector welfare professionals, viz. medical doctors, nurses, teachers, social workers. Comparisons are made with general population data from the International Social Survey Programme. Two methods of assessing the importance of work autonomy are employed; respondents’ direct ratings and statistical associations between work autonomy (and other job characteristics on the one hand and job satisfaction and organizational commitment on the other. Findings: Autonomy is not rated as more important among the professionals than in the general population, and neither is it more strongly related to job satisfaction. Interesting work and workplace social support appear to be more central.

  9. Autonomy, nudging and post-truth politics.

    2017-11-16

    In his excellent essay, 'Nudges in a post-truth world', Neil Levy argues that 'nudges to reason', or nudges which aim to make us more receptive to evidence, are morally permissible. A strong argument against the moral permissibility of nudging is that nudges fail to respect the autonomy of the individuals affected by them. Levy argues that nudges to reason do respect individual autonomy, such that the standard autonomy objection fails against nudges to reason. In this paper, I argue that Levy fails to show that nudges to reason respect individual autonomy. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

    Depression is quite common among young people in Hong Kong Chinese society. This study examined the association between emotional autonomy and depressive symptomatology among Chinese young people in Hong Kong. The respondents were 512 young people between 16 and 18 years of age from a cross-sectional study in Hong Kong. Significant bivariate relationships were found between depressive symptomatology and three dimensions of emotional autonomy (individuation, nondependency on parents, and deidealization of parents). Using multiple regression models, the author found that depressive symptomatology was associated with two aspects of emotional autonomy: individuation and deidealization of parents. Results indicate that the relationships between depressive symptomatology and these three aspects of emotional autonomy are similar in both individualistic and collectivistic societies.

    2014-10-01

    The elderly population is increasing rapidly in Taiwan. With the average life expectancy on the rise, the elderly have become major consumers of healthcare products and services. Factors that influence respect for autonomy, a core value of medical ethics, may be related to family, society, and the medical culture. Especially in patients who are already elderly, aging causes declines in physical, mental and societal capacities. Practicing a respect for patient autonomy is particularly challenging for healthcare professionals in Taiwan due the unique culture background of elderly Taiwanese patients. This article reviews and integrates the literature related to the issue of patient autonomy and elaborates on medical decision-making among elderly patients in Taiwan in the contexts of: the disadvantages faced by the elderly, the background of Chinese culture, and the current medical decision-making environment. A few suggestions are proposed to help preserve the medical-decision-making autonomy of elderly patients in Taiwan.

  14. Futility, autonomy, and informed consent.

    Science.gov (United States)

    Trau, J M

    1994-03-01

    If clinicians deem a treatment medically futile, is it appropriate to mention such a treatment to patients? Do healthcare professionals violate informed consent if they do not offer patients an opportunity to decline futile treatments? The notion of futility involves an assessment of patient best interest--both short-term and long-term therapeutic benefit for a patient and the community in which he or she intends to survive and flourish. Although survival interests may be construed as long term, a treatment that offers survival without any promise of flourishing is not the goal of medicine and is futile. Flourishing requires some cognitive and affective function. The goal of informed consent practices is to ensure that patients accept the benefits of treatment with cognizance of the burdens and risks. Given the impact of illness on the emotional and psychological states of patients and their families and their resultant vulnerability, the omission of futile options from treatment plans is logical and exemplifies the best of paternalistic behavior. The claim that requests for futile treatment must be honored is based on a perverse understanding of patient autonomy. Rational medicine demands that patients' requests be reasonable from a clinical perspective, as well as from a subjective one. The practice of informed consent can be implemented as a balance between these two interests.

This protection from paternalism is achieved by granting individuals rights ...

    A portable blood irradiator was developed at the Pacific Northwest Laboratory to evaluate the effects of chronic irradiation of the blood in suppressing graft rejection. The irradiator, designed to be worn on the arm or leg and be surgically connected in an arterio-venous shunt, uses beta radiation from activated thulium imbedded in a vitreous carbon matrix to reduce the number of lymphocytes circulating in the blood. The dose and energy spectra relative to the distance from and position around a prototype irradiator were measured by thermoluminescent dosimeters, ion chambers and photon spectroscopy. With computer simulations using those measurements, the shielding was redesigned to minimize the radiation dose to the patient and to the attending personnel and to minimize the weight of the irradiator. The new shielding design was incorporated into a new prototype, and the dose and spectral measurements were repeated, which confirmed the design improvements. 10 refs., 11 figs

    2018-03-01

    A portable torque wrench tester (PTWT) with calibration range from 0.5 Nm to 60 Nm has been developed and evaluated for periodic or on-site calibration of setting type torque wrenches, indicating type torque wrenches and hand torque screwdrivers. The PTWT is easy to carry with weight about 10 kg, simple and efficient operation and energy saving with an automatic loading and calibrating system. The relative expanded uncertainty of torque realized by the PTWT was estimated to be 0.8%, with the coverage factor k=2. A comparison experiment has been done between the PTWT and a reference torque standard at our laboratory. The consistency between these two devices under the claimed uncertainties was verified.

    Professional autonomy often causes confusion in nursing staffs that limit their ability to perform to the best of their professional capabilities. Moreover, heavy and busy workloads reduce the energy available for work resulting in lower working efficiency and lower job satisfaction. This study explores the status and factors related to professional autonomy and job satisfaction in nurses. A cross-sectional design was used to target the nurses employed at a regional hospital in southern Taiwan. Data on locus of control, professional autonomy, and job satisfaction were collected for analysis. Data were collected from 207 nurses, with 196 valid responses (response rate: 94.69%). One hundred and forty-six subjects (74.5%) were found to have an internal locus of control personality type. Scores for both professional autonomy and job satisfaction were above the "moderate" level (averages: 3.37 and 3.32, respectively, on a maximum scale of 5). Social demographic differences contributed to the variance in professional autonomy and job satisfaction among participants. Professional autonomy was found to be positively associated with job satisfaction. The findings of this study indicate that nurses with an internal locus of control personality exhibit higher professional autonomy and job satisfaction and that higher professional autonomy is associated with higher job satisfaction.

    2017-10-02

    Purpose The aim of this study was to describe Jordanian critical care nurses' experiences of autonomy in their clinical practice. Design/methodology/approach A descriptive correlational design was applied using a self-reported cross-sectional survey. A total of 110 registered nurses who met the eligibility criteria participated in this study. The data were collected by a structured questionnaire. Findings A majority of critical care nurses were autonomous in their decision-making and participation in decisions to take action in their clinical settings. Also, they were independent to develop their own knowledge. The study identified that their autonomy in action and acquired knowledge were influenced by a number of factors such as gender and area of practice. Practical implications Nurse's autonomy could be increased if nurses are made aware of the current level of autonomy and explore new ways to increase empowerment. This could be offered through classroom lectures that concentrate on the concept of autonomy and its implication in practice. Nurses should demonstrate autonomous nursing care at the same time in the clinical practice. This could be done through collaboration between educators and clinical practice to help merge theory to practice. Originality/value Critical care nurses were more autonomous in action and knowledge base. This may negatively affect the quality of patient care and nurses' job satisfaction. Therefore, improving nurses' clinical decision-making autonomy could be done by the support of both hospital administrators and nurses themselves.

  5. Autonomy and informed consent: a mistaken association?

    Science.gov (United States)

    Kristinsson, Sigurdur

    2007-09-01

    For decades, the greater part of efforts to improve regulatory frameworks for research ethics has focused on informed consent procedures; their design, codification and regulation. Why is informed consent thought to be so important? Since the publication of the Belmont Report in 1979, the standard response has been that obtaining informed consent is a way of treating individuals as autonomous agents. Despite its political success, the philosophical validity of this Belmont view cannot be taken for granted. If the Belmont view is to be based on a conception of autonomy that generates moral justification, it will either have to be reinterpreted along Kantian lines or coupled with a something like Mill's conception of individuality. The Kantian interpretation would be a radical reinterpretation of the Belmont view, while the Millian justification is incompatible with the liberal requirement that justification for public policy should be neutral between controversial conceptions of the good. This consequence might be avoided by replacing Mill's conception of individuality with a procedural conception of autonomy, but I argue that the resulting view would in fact fail to support a non-Kantian, autonomy-based justification of informed consent. These difficulties suggest that insofar as informed consent is justified by respect for persons and considerations of autonomy, as the Belmont report maintained, the justification should be along the lines of Kantian autonomy and not individual autonomy.

    International audience; We focus on the perceived autonomy of mathematics students in their first semester at university. According to self-determination theory by Deci and Ryan (1985), students have to satisfy their need for autonomy in order to develop intrinsic motivation. Using two facets of autonomy, we analyse interview data to explore which situations foster or hinder the students' perceived autonomy. The main factors affecting students' autonomy are briefly discussed.

    A portable counter which has been developed for prospecting for radio-active uranium and thorium minerals, for general geological investigations, and as an ultra-sensitive detector of lost or mislaid radium, is described. The aforementioned general usage includes the identification of changes in strata by means of the investigation of the slight amount of residual activity pressent in most minerals. The apparatus, which consists essentially of a scaled-down version of a standard laboratory Geiger-Muller counter, is highly sensitive since a variation equivalent to 4% of the cosmic ray background can be detected by a three-minute count.

    1995-01-01

    Radiography is a standard nondestructive technique in the industrial testing of materials and components. It is routinely used during the construction, maintenance and repair of nuclear plants. Traditionally, radiography is performed using photographic film (film radiography, FR). Recent developments in solid-state area imaging radiation detectors, miniature electronics and computer software/hardware techniques have brought electronic alternatives to FR. In recent years various electronic radiography (ER) techniques have served as alternatives to FR, these proved beneficial in some applications. While originally developed to provide real time imaging, ER may offer other advantages over FR, depending on the application. Work was undertaken at CRL to review progress in ER techniques and evaluate the possibility of constructing a portable DER (digital electronic radiography) system, for the inspection of power plant components. A suitable DER technique has been developed and a proof of principle portable system constructed. As this paper demonstrates, a properly designed ER system can be small and compact, while providing radiographic examination with acceptable image quality and the benefits of ER imaging. The CRL DER system can operate with radioactive sources typical of FR. While it does not replace FR, our DER system is expected to be beneficial in specific applications for Candu maintenance, reducing cost, labour and time. Practical, cost saving applications of this system are expected to include valve monitoring and foreign object location during maintenance at Candu reactors

    Pacific Northwest National Laboratory has designed and constructed a prototype portable neutron coincidence counter intended for use in a variety of applications, such as the verification and inspection of weapons components, safety measurements for novel and challenging situations, portable portal deployment to prevent the transportation of fissile materials, uranium enrichment measurements in hard-to-reach locations, waste assays for objects that cannot be measured by existing measurement systems, and decontamination and decommissioning. The counting system weighs less than 40 kg and is composed of parts each weighing no more than 5 kg. In addition, the counter`s design is sufficiently flexible to allow rapid, reliable assembly around containers of nearly arbitrary size and shape. The counter is able to discern the presence of 1 kg of weapons-grade plutonium within an ALR-8 (30-gal drum) in roughly 100 seconds and 10 g in roughly 1000 seconds. The counter`s electronics are also designed for maximum adaptability, allowing operation under a wide variety of circumstances, including exposure to gamma-ray fields of 1 R/h. This report provides a detailed review of the design and construction process. Finally, preliminary experimental measurements that confirm the performance capabilities of this counter are discussed. 6 refs., 18 figs., 3 tabs.

    An electrocardiograph was designed and implemented, being capable of obtaining electrical signals from the heart, and sending this data via Bluetooth to a tablet, in which the signals are graphically shown. The user interface is developed as an Android application. Because of the technological progress and the increasing use of full portable systems, such as tablets and cell phones, it is important to understand the functioning and development of an application, which provides a basis for conducting studies using this technology as an interface. The project development includes concepts of electronics and its application to achieve a portable and functional final project, besides using a specific programmable integrated circuit for electrocardiogram, electroencephalogram and electromyogram, the ADS1294. Using a simulator of cardiac signals, 36 different waveforms were recorded, including normal sinus rhythm, arrhythmias and artifacts. Simulations include variations of heart rate from 30 to 190 beats per minute (BPM), with variations in peak amplitude of 1 mV to 2 mV. Tests were performed with a subject at rest and in motion, observing the signals obtained and the damage to their interpretation due to the introduction of muscle movement artifacts in motion situations.

    Portable water quality monitoring system was a developed system that tested varied samples of water by using different sensors and provided the specific readings to the user via short message service (SMS) based on the conditions of the water itself. In this water quality monitoring system, the processing part was based on a microcontroller instead of Lead and Copper Rule (LCR) machines to receive the results. By using four main sensors, this system obtained the readings based on the detection of the sensors, respectively. Therefore, users can receive the readings through SMS because there was a connection between Arduino Uno and GSM Module. This system was designed to be portable so that it would be convenient for users to carry it anywhere and everywhere they wanted to since the processor used is smaller in size compared to the LCR machines. It was also developed to ease the user to monitor and control the water quality. However, the ranges of the sensors' detection still a limitation in this study.

    1997-06-01

    In recent years, the expense of creating good control software has led to a number of collaborative efforts among laboratories to share this cost. The EPICS collaboration is a particularly successful example of this trend. More recently another collaborative effort has addressed the need for sophisticated high level software, including model driven accelerator controls. This work builds upon the CDEV (Common DEVice) software framework, which provides a generic abstraction of a control system, and maps that abstraction onto a number of site-specific control systems including EPICS, the SLAC control system, CERN/PS and others. In principle, it is now possible to create portable accelerator control applications which have no knowledge of the underlying and site-specific control system. Applications based on CDEV now provide a growing suite of tools for accelerator operations, including general purpose displays, an on-line accelerator model, beamline steering, machine status displays incorporating both hardware and model information (such as beam positions overlaid with beta functions) and more. A survey of CDEV compatible portable applications will be presented, as well as plans for future development.

    A document discusses the Portable Health Algorithms Test (PHALT) System, which has been designed as a means for evolving the maturity and credibility of algorithms developed to assess the health of aerospace systems. Comprising an integrated hardware-software environment, the PHALT system allows systems health management algorithms to be developed in a graphical programming environment, to be tested and refined using system simulation or test data playback, and to be evaluated in a real-time hardware-in-the-loop mode with a live test article. The integrated hardware and software development environment provides a seamless transition from algorithm development to real-time implementation. The portability of the hardware makes it quick and easy to transport between test facilities. This hard ware/software architecture is flexible enough to support a variety of diagnostic applications and test hardware, and the GUI-based rapid prototyping capability is sufficient to support development execution, and testing of custom diagnostic algorithms. The PHALT operating system supports execution of diagnostic algorithms under real-time constraints. PHALT can perform real-time capture and playback of test rig data with the ability to augment/ modify the data stream (e.g. inject simulated faults). It performs algorithm testing using a variety of data input sources, including real-time data acquisition, test data playback, and system simulations, and also provides system feedback to evaluate closed-loop diagnostic response and mitigation control.

    2016-12-01

    In the Bioenergy and Defense Department of Sandia National Laboratories, characterization of the BaDx (Bacillus anthracis diagnostic cartridge) was performed and rapid germination chemistry was investigated. BaDx was tested with complex sample matrixes inoculated with Bacillus anthracis, and the trials proved that BaDx will detect Bacillus anthracis in a variety of the medium, such as dirt, serum, blood, milk, and horse fluids. The dimensions of the device were altered to accommodate an E. coli or Listeria lateral flow immunoassay, and using a laser printer, BaDx devices were manufactured to identify E. coli and Listeria. Initial testing with E. coli versions of BaDx indicate that the device will be viable as a portable diagnostic cartridge. The device would be more effective with faster bacteria germination; hence studies were performed the use of rapid germination chemistry. Trials with calcium dipicolinic acid displayed increased cell germination, as shown by control studies using a microplate reader. Upon lyophilization the rapid germination chemistry failed to change growth patterns, indicating that the calcium dipicolinic acid was not solubilized under the conditions tested. Although incompatible with the portable diagnostic device, the experiments proved that the rapid germination chemistry was effective in increasing cell germination.

    Conventional portable instruments for sensing chemical vapors have certain limitations for on-site use. In this article, we develop a genuinely portable detector that is sensitive, powerful, rugged, of simple design, and with very low power needs. Such a detector is based on a dry-cell battery-powered, capillary-discharge-based, microplasma source with optical emission detection. The microscale plasma source has very special features such as low thermal temperature and very low power needs. These features make it possible for the plasma source to be powered with a small dry-cell battery. A specially designed discharge chamber with minielectrodes can be configured to enhance the plasma stability and the system performance. A very small amount of inert gas can be used as sample carrier and plasma supporting gas. Inert gases possess high excitation potentials and produce high-energy metastable particles in the plasma. These particles provide sufficient energy to excite chemical species through Penning ionization and/or energy transfer from metastable species. A molecular emission spectrum can be collected with a palm-sized spectrometer through a collimated optical fiber. The spectrum can be displayed on a notebook computer. With this design and arrangement, the new detector provides high sensitivity for organic chemical species. The advantages and features of the newly developed detector include high sensitivity, simple structure, low cost, universal response, very low power consumption, compact volume with field portable capability, and ease of operation

    The achieving of high performance and long useful life are the two fundamental objectives of portable application designers. Cost and size conditions make these objectives more complex and always lead to a compromise solution having to be reached. The most significant parameters as regards portables devices are cost, efficiency (useful life), output crimps and noise, and quiescent current. Most portable products have two fundamental operating modes: active and standby. During the active period, current consumption is generally high and this means that excellent conversion is essential in order to maximize the useful life of the device that supplies current and voltage. However, most portable devices spend most of their time on standby and draw little energy from the source. It is equally important for the source to be very efficient under these conditions. This means that the quiescent current from the source (the current that supplies in low or nil load conditions) must be much lower than the load current in order to maintain high efficiency. Topologies Different power conditioning topologies to be used in portable applications are indicated with their corresponding advantages and inconveniences being specified. Low dropout voltage regulator (LDO) This type of conditioning is one of minimum cost, noise and quiescent current. This makes this device a favorite for many applications. Its external components are minimal: usually a bypass capacity. Its efficiency, although poor when Vin is much greater than Vout, increases greatly when their values are somewhat similar. In this event, the benefits of using LDOs are almost impossible to beat. In fact, these circuits are much used to reach output voltages of up to 3 volts. (Author)

    Full Text Available This work deals with the development of autonomy in the education of the child and focuses on the analysis of empirical data collected in some services for children in North and South of Italy (Trento, Bologna, Caltagirone, through the administration of semi-structured interviews with educators of the nursery and kindergarten teachers. The returned responses were read in the light of the phenomenological paradigm that permitted to highlight two major kinds of considerations: the one refers to as "parents support and encourage the development of the autonomy of their child more in words than deeds"; the other to as the educators and teachers interviewed showed an explicit difficulty to attribute a clear meaning to the concept of adult autonomy. The incoming in this set of considerations first of all emphasize the important role of adult education and its path of reflexivity and growth.

  7. The autonomy of grammar and semantic internalism

    2014-01-01

    Full Text Available In his post-Tractatus work on natural language use, Wittgenstein defended the notion of what he dubbed the autonomy of grammar. According to this thought, grammar - or semantics, in a more recent idiom - is essentially autonomous from metaphysical considerations, and is not answerable to the nature of things. The argument has several related incarnations in Wittgenstein’s post-Tractatus writings, and has given rise to a number of important insights, both critical and constructive. In this paper I will argue for a potential connection between Wittgenstein’s autonomy argument and some more recent internalist arguments for the autonomy of semantics. My main motivation for establishing this connection comes from the fact that the later Wittgenstein’s comments on grammar and meaning stand in opposition to some of the core assumptions of semantic externalism.

    The purpose of this study was to explore Kanter's Theory of Structural Power in Organizations, using school nurses and to answer the research question of whether there is a relationship between empowerment and autonomy in school nurses. This study found a positive relationship between the nurses' perceptions of empowerment and autonomy. The school nurses surveyed perceived themselves to have a high degree of autonomy and a moderate degree of empowerment, and they reported that their access to informal power structures was higher than their access to formal power structures in their school systems. School nurses can benefit by understanding factors that can increase their empowerment in the workplace. They need to understand the organizational structure of their workplace to increase their effectiveness and job satisfaction.

    The final report on Project RP 822-6 describes the MINAC 3 development from the recognition of need for a lightweight, portable high-energy device to the successful completion and field use of the MINAC. MINAC, which represents a substantial improvement in field radiographic capability and in technology, rapidly transitioned from proof-of-principle (1978 to 1980) to field-proven product (1980 to 1981). As a result, the decision has been made to develop this report as a users guide as well as a historic record of design, development, and testing program. The first section of this report has the following principal objectives: to describe the existing MINAC equipment capabilities and achievable modifications; to provide applications information for prospective users; and to provide technical information on high-energy radiography useful for familiarization and planning. The users guide section is followed by sections which describe the design basis, development, and application history of MINAC through the course of EPRI RP822 research projects 1 to 5, inclusively

All medical device digital functions are performed by the microcontroller. The electrocardiograph CPU is based on the 18F4550 microcontroller, in which an uCOS-II RTOS can be embedded. The decision associated with the kernel use is based on its benefits, the license for educational use and its intrinsic time control and peripherals management. The feasibility of its use on the electrocardiograph is evaluated based on the minimum memory requirements due to the kernel structure. The kernel's own tools were used for time estimation and evaluation of resources used by each process. After this feasibility analysis, the migration from cyclic code to a structure based on separate processes or tasks able to synchronize events is used; resulting in an electrocardiograph running on one Central Processing Unit (CPU) based on RTOS.

    2003-07-01

    The 1st generation acoustic monitoring package was designed to detect and analyze weak acoustic signals inside natural gas transmission lines. Besides a microphone it housed a three-inch diameter aerodynamic acoustic signal amplifier to maximize sensitivity to leak induced {Delta}p type signals. The theory and test results of this aerodynamic signal amplifier was described in the master's degree thesis of our Research Assistant Deepak Mehra who is about to graduate. To house such a large three-inch diameter sensor required the use of a steel 300-psi rated 4 inch weld neck flange, which itself weighed already 29 pounds. The completed 1st generation Acoustic Monitoring Package weighed almost 100 pounds. This was too cumbersome to mount in the field, on an access port at a pipeline shut-off valve. Therefore a 2nd generation and truly Portable Acoustic Monitor was built. It incorporated a fully self-contained {Delta}p type signal sensor, rated for line pressures up to 1000 psi with a base weight of only 6 pounds. This is the Rosemont Inc. Model 3051CD-Range 0, software driven sensor, which is believed to have industries best total performance. Its most sensitive unit was purchased with a {Delta}p range from 0 to 3 inch water. This resulted in the herein described 2nd generation: Portable Acoustic Monitoring Package (PAMP) for pipelines up to 1000 psi. Its 32-pound total weight includes an 18-volt battery. Together with a 3 pound laptop with its 4-channel data acquisition card, completes the equipment needed for field acoustic monitoring of natural gas transmission pipelines.

    2015-01-01

    Full Text Available In situ applications require a very high level of portability of high-resolution spectrometric equipment. Usage of HPGe detectors for radioactivity measurements in the environment or for nuclear safeguard applications, to combat illicit trafficking of nuclear materials or uranium and plutonium monitoring in nuclear wastes, has become a norm in the recent years. Portable HPGe-based radionuclide spectrometer with electrical cooling has lately appeared on the market for in situ applications. At the same time deterioration of energy resolution associated with vibrations produced by cryocooler or high weight of the instrument, short time of autonomous operation and high price of these spectrometers are limiting their usage in many cases. In this paper we present development results of ultra compact hand held all-in-one spectrometer for in situ measurements based on HPGe detector cooled by liquid nitrogen without listing the above disadvantages.

  9. How Sex Selection Undermines Reproductive Autonomy.

    Science.gov (United States)

    Browne, Tamara Kayali

    2017-06-01

    Non-medical sex selection is premised on the notion that the sexes are not interchangeable. Studies of individuals who undergo sex selection for non-medical reasons, or who have a preference for a son or daughter, show that they assume their child will conform to the stereotypical roles and norms associated with their sex. However, the evidence currently available has not succeeded in showing that the gender traits and inclinations sought are caused by a "male brain" or a "female brain". Therefore, as far as we know, there is no biological reason why parents cannot have the kind of parenting experience they seek with a child of any sex. Yet gender essentialism, a set of unfounded assumptions about the sexes which pervade society and underpin sexism, prevents parents from realising this freedom. In other words, unfounded assumptions about gender constrain not only a child's autonomy, but also the parent's. To date, reproductive autonomy in relation to sex selection has predominantly been regarded merely as the freedom to choose the sex of one's child. This paper points to at least two interpretations of reproductive autonomy and argues that sex selection, by being premised on gender essentialism and/or the social pressure on parents to ensure their children conform to gender norms, undermines reproductive autonomy on both accounts.

    In the early 1970s Harry Frankfurt argued that so-called ‘coercive threats’ cause a violation of their victim's autonomy, thereby excluding him from moral responsibility. A person is therefore not responsible for doing what he is forced to do. Although this seems correct on an intuitive level, I

    The doctrine of university autonomy in the UK contains a least two major "fault-lines" where the structure is inherently weak and there is danger of functional breakdown. The first occurs at the junction between the institution and the state, the second within the institution, where the unity in policy-making between academic and…

  19. Patient autonomy: a view from the kitchen.

    Science.gov (United States)

    Struhkamp, Rita M

    2005-01-01

    In contemporary liberal ethics patient autonomy is often interpreted as the right to self-determination: when it comes to treatment decisions, the patient is given the right to give or withhold informed consent. This paper joins in the philosophical and ethical criticism of the liberal interpretation as it does not regard patient autonomy as a right, rule or principle, but rather as a practice. Patient autonomy, or so I will argue, is realised in the concrete activities of day-to-day health care, in the material and technological context of care, in arrangements of health care institutions, in the physical training of people with disabilities, as well as in the concrete activities of care-giving. This move from conversations in the consultation room to other sites and situations in the practice of care takes seriously the empirical reality of medical care and intends to show that patient autonomy is practically realised in a much richer and more creative way than most ethical theory seems to assume.

    2017-05-01

    Sandia has identified autonomy as a strategic initiative and an important area for providing national leadership. A key question is, “How might autonomy change how we think about the national security challenges we address and the kinds of solutions we deliver?” Three workshops at Sandia early in 2017 brought together internal stakeholders and potential academic partners in autonomy to address this question. The first focused on programmatic applications and needs. The second explored existing internal capabilities and research and development needs. This report summarizes the outcome of the third workshop, held March 3, 2017 in Albuquerque, NM, which engaged Academic Alliance partners in autonomy efforts at Sandia by discussing research needs and synergistic areas of interest within the complex systems and system modeling domains, and identifying opportunities for partnering on laboratory directed and other joint research opportunities.

  11. Physicians’ Perceptions of Autonomy across Practice Types: Is Autonomy in Solo Practice a Myth?

    Science.gov (United States)

    Lin, Katherine Y.

    2013-01-01

    Physicians in the United States are now less likely to practice in smaller, more traditional, solo practices, and more likely to practice in larger group practices. Though older theory predicts conflict between bureaucracy and professional autonomy, studies have shown that professions in general, and physicians in particular, have adapted to organizational constraints. However, much work remains in clarifying the nature of this relationship and how exactly physicians have adapted to various organizational settings. To this end, the present study examines physicians’ autonomy experiences in different decision types between organization sizes. Specifically, I ask: In what kinds of decisions do doctors perceive autonomous control? How does this vary by organizational size? Using stacked “spell” data constructed from the Community Tracking Study (CTS) Physician Survey (1996–2005) (n=16,519) I examine how physicians’ perceptions of autonomy vary between solo/two physician practices, small group practices with three to ten physicians, and large practices with ten or more physicians, in two kinds of decisions: logistic-based and knowledge-based decisions. Capitalizing on the longitudinal nature of the data I estimate how changes in practice size are associated with perceptions of autonomy, accounting for previous reports of autonomy. I also test whether managed care involvement, practice ownership, and salaried employment help explain part of this relationship. I find that while physicians practicing in larger group practices reported lower levels of autonomy in logistic-based decisions, physicians in solo/two physician practices reported lower levels of autonomy in knowledge-based decisions. Managed care involvement and ownership explain some, but not all, of the associations. These findings suggest that professional adaptation to various organizational settings can lead to varying levels of perceived autonomy across different kinds of decisions. PMID:24444835

  13. LEARNER AUTONOMY IN THE INDONESIAN EFL SETTINGS

    Directory of Open Access Journals (Sweden)

    2017-01-01

    Full Text Available Learner autonomy in Indonesian educational institutions has not commonly been listed as a teaching-learning objective, and most teachers seem to be hardly acquainted with learner autonomy (LA.  Therefore, it is very essential  to conduct a study of LA as perceived and experienced by school teachers and to find out the importance of LA training for professional development. A questionnaire was used to collect the data about English teachers’ perceptions regarding LA and LA-based practices. In addition, an LA training was conducted to see its significance for professional development.  After the data were qualitatively and quantitatively analyzed, it was found that the participating teachers tended to maintain that autonomy should be inculcated among learners, and that the LA concept should not be misinterpreted as learning without a teacher. Concerning choices and decisions by  the learners, it was believed that learners’ making choices about how they learned and what activities they did, and involving them to decide what and how to learn could promote autonomy among learners. As regards LA-based teaching-learning practices, it was revealed that most teachers desired to implement LA principles in their teaching-learning contexts, although they identified that many of the LA principles were not that feasible to apply in their situation. It was also found that LA training could improve the teachers’ perceptions regarding LA concepts and principles. There were some constraints which could make learner autonomy difficult to develop among Indonesian learners in general: limited time allotted for the implementation of the curriculum, learners’ lack of autonomous learning experience, too much focus on national examinations, and insufficient proficiency of English.  LA-based teaching-learning practices were most desired; however, many were considered as having insufficient feasibility. In this respect, commitment is certainly the key to

  14. [Autonomy and dementia Part II: autonomy and representation: a possible combination?].

    Science.gov (United States)

    Rigaux, Natalie

    2011-06-01

    This paper, based on a critical review of the medico-social literature, questions the representation of patients with dementia in relation to the autonomy perspectives presented in a previous article. In the canonical perspective of autonomy (defined as a rational decision-making by a stand alone self), the surrogate is the spokeperson of the subject's wills when he was competent because he knows these wills through advance directives or assuming them via substituted judgment. Best patient's interest is then depreciated because it is focused on the present incompetent self. In the relational perspective, where autonomy is constructed through a dialogue with others, the surrogate is the present interlocutor, making the decisions with the patient and care-givers in a way varying with the disease process. He represents the subject with dementia as he was before the disease but also as he has become. Therefore, there is a continuum between autonomy and representation. Autonomy and well being are both the surrogate aims. The relational perspective allows care continuity of patients with dementia even when considered as incompetent. It offers a more balanced perspective on the patient autonomy since it is embedded in all others, and opens a richer view on what good life is, untill the end of dementia.

    2014-01-01

    The rapid and automatic identification of radionuclides present in a radioactive sample detected in the field, is information that helps in decision making. In areas of high traffic of people and materials, such as ports and airports as well as at major events, radiation monitoring, together with the identification of the radionuclide, it is advisable within protective standards to the public. The correct identification of radionuclides depends on the ability to determine whether specific peaks energy sources are present in the spectrum of gamma radiation sources. Radionuclides can be identified by these energy characteristics in the sense that the energy value associated with these peaks in the spectrum corresponds to the radiation sources present in the sample. There are many methods that can be used for automatic identification of radionuclides. Most of them are based on software algorithms for the detection of peaks in the energy spectrum. Processing time of these tasks can be very long for applications requiring quick responses, as in equipment portable. A dedicated digital hardware offers better performance for tasks with high processing demand like this. This work shows the development of a handle Portable radionuclides based on a digital hardware solution using a FPGA (Field Programmable Gate Array) for implementing a clustering algorithm for the detection of energy peaks.

    The components of the portable spectrometric assembly are: - the detecting probe with Na I(Tl) crystal and air-tight case of industrial type; - a microcomputer; - a unit of analogical processing of the signal from the detecting probe; - a single-channel analyzer with adjustable threshold; - commands and display module; - a source of high voltage; - an electrical supply battery. The device uses the method of gamma photons detection in energetic windows. Through theoretical and experimental studies carried out during the prototype development phase, the superiority of this method has been proved as compared with the installations which make use of the classical principle of photon integral detection. The achieved prototype has a basic program enabling the setting of all working parameters (measuring time, discriminating thresholds, discriminators operating conditions, etc.). Through the included interface RS232 it is possible to transmit the data to a more powerful computer in order to continually process the results. The spectrometric assembly, realized on the basis of micro-computers, can be used in a wide range of applications: measurement of thickness and erosion of walls and tubes, measurement of level in closed containers, of soil density, etc. The adjustment for specific application is performed only through a program modification.

    1996-12-31

    Sanyo Electric has been concentrating on developing a marketable portable fuel cell using phosphoric acid fuel cells (PAFC). Due to the fact that this power source uses PAFC that operate at low temperature around 100{degrees} C, they are easier to handle compared to conventional fuel cells that operate at around 200{degrees} C , they can also be expected to provide extended reliable operation because corrosion of the electrode material and deterioration of the electrode catalyst are almost completely nonexistent. This power source is meant to be used independently and stored at room temperature. When it is started up, it generates electricity itself using its internal load to raise the temperature. As a result, the phosphoric acid (the electolyte) absorbs the reaction water when the temperature starts to be raised (around room temperature). At the same time the concentration and volume of the phosphoric acid changes, which may adversely affect the life time of the cell. We have studied means for starting, operating PAFC stack using methods that can simply evaluate changes in the concentration of the electrolyte in the stack with the aim of improving and extending cell life and report on them in this paper.

    International Nuclear Information System (INIS)

    Mason, E.W.; Weber, J.M.

    1984-01-01

    A portable microcomputer controlled counter for use as a radiation counter is described. The counter uses digital processing of input pulses from a radiation detector. The number of counts received by the microcomputer per unit time is used to calculate a value for display using a calibration factor obtained during physical calibration of the instrument with a radiation source or with a pulse generator. The keyboard is used to enter calibration points. The number of calibration points which may be entered depends on the degree of accuracy desired by the user. The high voltage generator which drives the detector is triggered by pulses from the microcomputer in relation to the count rate. After processing the count, the resulting count rate or dose rate is displayed on the liquid crystal display. The counter is autoranging in which the decimal point is shifted as necessary by the microcomputer. The units displayed are determined by the user by means of a multiposition switch. Low battery and an overrange condition are displayed. An interface is provided via a connector to allow parallel transmission of data to peripheral devices. Low battery power consumption is featured. The counter is capable of providing more accurate readings than currently available counters

    A portable Moessbauer spectrometer, developed for extraterrestrial applications, opens up new industrial applications of MBS. But for industrial applications, an available tool for fast data analysis is also required, and it should be easy to handle. The analysis of Moessbauer spectra and their parameters is a barrier for the popularity of this wide-applicable spectroscopic technique in industry. Based on experience, the analysis of a Moessbauer spectrum is time-consuming and requires the dedication of a specialist. However, the analysis of Moessbauer spectra, from the fitting to the identification of the sample phases, can be faster using by genetic algorithms, fuzzy logic and artificial neural networks. Industrial applications are very specific ones and the data analysis can be performed using these algorithms. In combination with an automatic analysis, the Moessbauer spectrometer can be used as a probe instrument which covers the main industrial needs for an on-line monitoring of its products, processes and case studies. Some of these real industrial applications will be discussed.

    For illumination sources designers is important to know the illumination distribution of their products. They can use several viewers of IES files (standard file format determined by Illuminating Engineering Society). This files are necessary not only know the distribution of illumination, but also to plain the construction of buildings by means of specialized softwares, such as Autodesk Revit. In this paper, a complete portable system for luminaries' characterization is given. The components of the systems are: Irradiance profile meter, which can generate photometry of luminaries of small sizes which covers indoor illumination requirements and luminaries for general areas. One of the meteŕs attributes is given by the color sensor implemented, which allows knowing the color temperature of luminary under analysis. The Graphic Unit Interface (GUI) has several characteristics: It can control the meter, acquires the data obtained by the sensor and graphs them in 2D under Cartesian and polar formats or 3D, in Cartesian format. The graph can be exported to png, jpg, or bmp formats, if necessary. These remarkable characteristics differentiate this GUI. This proposal can be considered as a viable option for enterprises of illumination design and manufacturing, due to the relatively low investment level and considering the complete illumination characterization provided.

    Design optimization, manufacturing, and tests, both laboratory and clinical, of a portable gamma camera for medical applications are presented. This camera, based on a continuous scintillation crystal and a position-sensitive photomultiplier tube, has an intrinsic spatial resolution of ≅2 mm, an energy resolution of 13% at 140 keV, and linearities of 0.28 mm (absolute) and 0.15 mm (differential), with a useful field of view of 4.6 cm diameter. Our camera can image small organs with high efficiency and so it can address the demand for devices of specific clinical applications like thyroid and sentinel node scintigraphy as well as scintimammography and radio-guided surgery. The main advantages of the gamma camera with respect to those previously reported in the literature are high portability, low cost, and weight (2 kg), with no significant loss of sensitivity and spatial resolution. All the electronic components are packed inside the minigamma camera, and no external electronic devices are required. The camera is only connected through the universal serial bus port to a portable personal computer (PC), where a specific software allows to control both the camera parameters and the measuring process, by displaying on the PC the acquired image on 'real time'. In this article, we present the camera and describe the procedures that have led us to choose its configuration. Laboratory and clinical tests are presented together with diagnostic capabilities of the gamma camera

    In this work, a portable atomic frequency standard based on coherent population trapping is designed and demonstrated. To achieve a portable prototype, in the system, a single transverse mode 795nm VCSEL modulated by a 3.4GHz RF source is used as a pump laser which generates coherent light fields. The pump beams pass through a vapor cell containing atom gas and buffer gas. This vapor cell is surrounded by a magnetic shield and placed inside a solenoid which applies a longitudinal magnetic field to lift the Zeeman energy levels' degeneracy and to separate the resonance signal, which has no first-order magnetic field dependence, from the field-dependent resonances. The electrical control system comprises two control loops. The first one locks the laser wavelength to the minimum of the absorption spectrum; the second one locks the modulation frequency and output standard frequency. Furthermore, we designed the micro physical package and realized the locking of a coherent population trapping atomic frequency standard portable prototype successfully. The short-term frequency stability of the whole system is measured to be 6×10-11 for averaging times of 1s, and reaches 5×10-12 at an averaging time of 1000s.

    2015-01-01

    A set of portable meters of ionizing radiation high rates of air kerma (teletectors) commonly used in emergencies in Brazil and sent to the Calibration Laboratory of IPEN were under several tests and analyst is parameters for the detectors behavior were established, specifying their sensitivities and operating characteristics. Applied tests were: reading equipment variation with battery voltage, geotropism effect, energy dependence, the angular dependence and overload. Thus it was possible to determine the most common characteristic found in these equipment (quality control programs). The behavior of 17 portable meters was analyzed and in this study, 10 of them have been tested. It was performed to characterize the gamma irradiating system (radiation dosimetry field) that possesses higher activity in teletectors for testing of larger measuring range. New calibration criteria were established following international recommendations. Therefore, it was made the improvement of the quality control programme of portable meters of ionizing radiation high rates of air kerma calibration laboratory, benefiting the users of such equipment with better consistent calibration measurements.

  8. A balanced intervention ladder: promoting autonomy through public health action.

    Griffiths, P E; West, C

    2015-08-01

    The widely cited Nuffield Council on Bioethics 'Intervention Ladder' structurally embodies the assumption that personal autonomy is maximized by non-intervention. Consequently, the Intervention Ladder encourages an extreme 'negative liberty' view of autonomy. Yet there are several alternative accounts of autonomy that are both arguably superior as accounts of autonomy and better suited to the issues facing public health ethics. We propose to replace the one-sided ladder, which has any intervention coming at a cost to autonomy, with a two-sided 'Balanced Intervention Ladder,' where intervention can either enhance or diminish autonomy. We show that not only the alternative, richer accounts of autonomy but even Mill's classic version of negative liberty puts some interventions on the positive side of the ladder.

    Effect of neurofeedback training (NFT) on enhancement of cognitive function or amelioration of clinical symptoms is inconclusive. The trainability of brain rhythm using a neurofeedback system is uncertainty because various experimental designs are used in previous studies. The current study aimed to develop a portable wireless NFT system for alpha rhythm and to validate effect of the NFT system on memory with a sham-controlled group. The proposed system contained an EEG signal analysis device and a smartphone with wireless Bluetooth low-energy technology. Instantaneous 1-s EEG power and contiguous 5-min EEG power throughout the training were developed as feedback information. The training performance and its progression were kept to boost usability of our device. Participants were blinded and randomly assigned into either the control group receiving random 4-Hz power or Alpha group receiving 8-12-Hz power. Working memory and episodic memory were assessed by the backward digital span task and word-pair task, respectively. The portable neurofeedback system had advantages of a tiny size and long-term recording and demonstrated trainability of alpha rhythm in terms of significant increase of power and duration of 8-12 Hz. Moreover, accuracies of the backward digital span task and word-pair task showed significant enhancement in the Alpha group after training compared to the control group. Our tiny portable device demonstrated success trainability of alpha rhythm and enhanced two kinds of memories. The present study suggest that the portable neurofeedback system provides an alternative intervention for memory enhancement.

  20. Autonomy, Competence and Non-interference.

    Science.gov (United States)

    Roberts, Joseph T F

    2017-12-30

    In light of the variety of uses of the term autonomy in recent bioethics literature, in this paper, I suggest that competence, not being as contested, is better placed to play the anti-paternalistic role currently assigned to autonomy. The demonstration of competence, I will argue, can provide individuals with robust spheres of non-interference in which they can pursue their lives in accordance with their own values. This protection from paternalism is achieved by granting individuals rights to non-interference upon demonstration of competence. In this paper, I present a risk-sensitive account of competence as a means of grounding rights to non-interference. On a risk-sensitive account of competence individuals demonstrate their competence by exercising three capacities to the extent necessary to meet a threshold determined by the riskiness of the decision. These three capacities are the capacity to (i) acquire knowledge, (ii) use instrumental rationality, and (iii) form and revise a life plan.

    Siqueira-Batista, Rodrigo; Schramm, Fermin Roland

    2008-01-01

    The principle of respect for autonomy has proved very useful for bioethical arguments in favor of euthanasia. However unquestionable its theoretical efficacy, countless aporiae can be raised when conducting a detailed analysis of this concept, probably checkmating it. Based on such considerations, this paper investigates the principle of autonomy, starting with its origins in Greek and Christian traditions, and then charting some of its developments in Western cultures through to its modern formulation, a legacy of Immanuel Kant. The main paradoxes of this concept are then presented in the fields of philosophy, biology, psychoanalysis and politics, expounding several of the theoretical difficulties to be faced in order to make its applicability possible within the scope of decisions relating to the termination of life.

  2. Autonomy, rationality and the wish to die.

    Science.gov (United States)

    Clarke, D M

    1999-12-01

    Although suicide has traditionally carried a negative sanction in Western societies, this is now being challenged, and while there remains substantial public concern surrounding youth and elder suicide, there is a paradoxical push to relax the prohibition under certain circumstances. Central to the arguments behind this are the principles of respect for autonomy and the importance of rationality. It is argued here that the concepts of rationality and autonomy, while valuable, are not strong enough to substantiate a categorical "right to suicide" and that the concepts of "understandability" and "respect" are more useful and able to provide the foundation for responding to a person expressing a wish to die. Roman suicide, sometimes held as an example of "rational suicide", illustrates the effects of culture, tradition and values on the attitudes to, and the practice of, suicide.

  3. Building up Autonomy Through Reading Strategies

    Directory of Open Access Journals (Sweden)

    Alexander Izquierdo Castillo

    2014-10-01

    Full Text Available This article reports on an action research project conducted with six ninth grade students in a rural public school in Colombia. The purpose of the study was to determine how the implementation of three reading strategies (skimming, scanning, and making predictions, when reading topics selected by learners, helps them to improve their reading comprehension and promotes their autonomy in the learning process. The results show that these learners developed some autonomous features such as making decisions for learning and doing assigned homework, increasing reading awareness and motivation. Additionally, the training on reading strategies allowed them to succeed in their reading comprehension. We conclude that these reading strategies are tools that take learners along the path of autonomy.

    This study seeks to emphasize school food as an important policy to promote student autonomy by means of food and nutrition education included in the curriculum, integrated with different actors and based on the standpoint of citizenship. It seeks to return to fundamental concepts in the context of school food reflecting on them through theoretical assumptions to identify possible strategies to promote citizenship and autonomy in school. The strategies involved food and nutrition education with the daily presence of quality and suitability in school meals, discussions on the various dimensions of food in the curriculum and integrating food in the pedagogical project extended to various areas of the education system. School food fosters the need for integration of actions, actors and the various social spaces interested in the food issue, such as ministries, education systems, departments and schools, so that they may tackle the demands of contemporary reality in an integrated, systematic, consistent and efficient manner.

    Autonomy-supportive parenting yields manifold benefits. To gain more insight into the family-level dynamics involved in autonomy-supportive parenting, the present study addressed three issues. First, on the basis of self-determination theory, we examined whether mothers' satisfaction of the psychological needs for autonomy, competence, and relatedness related to autonomy-supportive parenting. Second, we investigated maternal autonomy support as an intervening variable in the mother-child similarity in psychological need satisfaction. Third, we examined associations between autonomy-supportive parenting and autonomy-supportive sibling interactions. Participants were 154 mothers (M age = 39.45, SD = 3.96) and their two elementary school-age children (M age = 8.54, SD = 0.89 and M age = 10.38, SD = 0.87). Although mothers' psychological need satisfaction related only to maternal autonomy support in the younger siblings, autonomy-supportive parenting related to psychological need satisfaction in both siblings and to an autonomy-supportive interaction style between siblings. We discuss the importance of maternal autonomy support for family-level dynamics. © 2015 by the Society for Personality and Social Psychology, Inc.

  12. Maximing Learning Strategies to Promote Learner Autonomy

    Directory of Open Access Journals (Sweden)

    Junaidi Mistar

    2001-01-01

    Full Text Available Learning a new language is ultimately to be able to communicate with it. Encouraging a sense of responsibility on the part of the learners is crucial for training them to be proficient communicators. As such, understanding the strategies that they employ in acquiring the language skill is important to come to ideas of how to promote learner autonomy. Research recently conducted with three different groups of learners of English at the tertiary education level in Malang indicated that they used metacognitive and social startegies at a high frequency, while memory, cognitive, conpensation, and affective strategies were exercised at a medium frewuency. This finding implies that the learners have acquired some degrees of autonomy because metacognive strategies requires them to independently make plans for their learning activities as well as evaluate the progress, and social strategies requires them to independently enhance communicative interactions with other people. Further actions are then to be taken increase their learning autonomy, that is by intensifying the practice of use of the other four strategy categories, which are not yet applied intensively.

  13. Cognitive Architectures and Autonomy: A Comparative Review

    Science.gov (United States)

    Thórisson, Kristinn; Helgasson, Helgi

    2012-05-01

    One of the original goals of artificial intelligence (AI) research was to create machines with very general cognitive capabilities and a relatively high level of autonomy. It has taken the field longer than many had expected to achieve even a fraction of this goal; the community has focused on building specific, targeted cognitive processes in isolation, and as of yet no system exists that integrates a broad range of capabilities or presents a general solution to autonomous acquisition of a large set of skills. Among the reasons for this are the highly limited machine learning and adaptation techniques available, and the inherent complexity of integrating numerous cognitive and learning capabilities in a coherent architecture. In this paper we review selected systems and architectures built expressly to address integrated skills. We highlight principles and features of these systems that seem promising for creating generally intelligent systems with some level of autonomy, and discuss them in the context of the development of future cognitive architectures. Autonomy is a key property for any system to be considered generally intelligent, in our view; we use this concept as an organizing principle for comparing the reviewed systems. Features that remain largely unaddressed in present research, but seem nevertheless necessary for such efforts to succeed, are also discussed.

  14. Multiculturalism and legal autonomy for cultural minorities

    Directory of Open Access Journals (Sweden)

    Morten Ebbe Juul Nielsen

    2013-11-01

    Full Text Available Does multiculturalism imply that certain cultural minorities – nomos groups, whose cultural conceptions extend in important ways into views about the law – should have forms of legal autonomy that go beyond normal multicultural accommodations such as exemptions and special protection? In other words: should we allow «minority jurisdictions» for multicultural reasons and give certain minorities powers of legislation and adjudication on certain issues? The paper sketches how one might arrive at such a conclusion given some standard multicultural reasoning, and then proceeds by examining eight key rejoinders to such a proposal. None of these rejoinders provide by themselves knockdown arguments against extending multicultural rights to forms of legal autonomy, but together they do provide a basis for some skepticism about the cogency and desirability of at least more ambitious forms of legal autonomy for cultural minorities within a liberal framework.http://dx.doi.org/10.5324/eip.v7i2.1798

    2000-05-01

    The Micro-Fuel Cell{sup TM} is a new power supply which provides a superior alternative compared to rechargeable batteries. A prototype has been developed by Manhattan Scientifics Inc. in collaboration with Energy Related Devices Inc. This mass-producible high-energy power supply can be used for cellular telephones, portable computers and other portable devices. Instead of being recharged, it can be easily refueled with methanol. The approach taken in designing this product was to develop a competitive product with definite advantages over existing products. The Micro-Fuel Cell{sup TM} is based on the idea that a fuel cell can be built onto an engineered microplastic substrate. In this case, the integrated design makes use of thin film vacuum deposition techniques to coat patterned, etched-nuclear-particle-track plastic membranes. This process forms catalytically active surface area electrodes on either side of a single structured proton-exchange-membrane electrolyte. Methanol was the choice fuel for this system because compared to hydrogen and metal hydrides, it was considered to be safer and more compact. In addition, the theoretical specific energy of methanol is significantly higher than for lithium-ion batteries. The problem of crossover, whereby methanol fuel diffuses across the fuel cell from the anode to the cathode, has also been solved by using a selectively permeable membrane. 5 refs., 4 figs.

    In this paper the most relevant developments in the realisation of portable energy-dispersive X-ray fluorescence (EDXRF) equipments are discussed. In particular, the latest advances in non-cryogenic (Peltier cooled) X-ray detectors and miniaturised X-ray generators are shown. The energy resolution of the new detection systems is adequate to resolve the characteristic X-ray emission lines of contiguous elements. This small size and low power make the system ideal for portable instrumentation and have stimulated the development of small- and low-power X-ray generators which can be used for the excitation of fluorescence radiation in a broad energy range (5-40 keV). Finally, the use of EDXRF related to archaeometric research (pigments in ancient paintings and major elements in the metal alloys) is emphasised. Recent results obtained with new HgI 2 and silicon PIN detector systems combined with miniaturised highly stable air-cooled X-ray generators are described. (orig.)

    Analysis of functional autonomy in euthyroid goitre. Methods: In an area of moderate iodine deficiency 163 goitrous patients without and 179 with functional autonomy all clinically euthyroid were compared by sex, age, signs and symptoms, sonographic results, qualitative and quantitative scintigraphy without and with suppression, TRH test, hormone concentrations and iodine excretion in the urine. Results: Age, signs and symptoms, thyroid volume and structure did not contribute sufficiently to diagnosis. To detect functional autonomy quantitative scintigraphy under suppression was superior to the TRH test. Increased hormone concentrations were observed in 15% of patients with functional autonomy. A global 99m Tc thyroid uptake of ≥3% under suppression indicates a higher risk of spontaneous hyperthyroidism. It was present in 20% of patients with functional autonomy. Conclusion: to diagnose and treat adequately functional autonomy in euthyroid goitre quantitative scintigraphy, determination of TSH and hormone concentrations are inevitable. (orig.) [de

    OBJECTIVE. To describe environmental barriers, accessibility problems, and powered mobility device (PMD) users’ autonomy indoors and outdoors; to determine the home environmental barriers that generated the most housing accessibility problems indoors, at entrances, and in the close exterior surroundings; and to examine personal factors and environmental components and their association with indoor and outdoor autonomy. METHOD. This cross-sectional study was based on data collected from a sample of 48 PMD users with a spinal cord injury (SCI) using the Impact of Participation and Autonomy and the Housing Enabler instruments. Descriptive statistics and logistic regression were used. RESULTS. More years living with SCI predicted less restriction in autonomy indoors, whereas more functional limitations and accessibility problems related to entrance doors predicted more restriction in autonomy outdoors. CONCLUSION. To enable optimized PMD use, practitioners must pay attention to the relationship between client autonomy and housing accessibility problems. PMID:26356666

    2006-07-01

    A new fuel cell technology for portable applications was reviewed. Success for the fuel cell industry will be achieved primarily by supplanting lithium-ion batteries, and fuel cells for portable applications have clear advantages to batteries in addition to their known environmental benefits. Micro hydrogen {sup TM} is the integrated combination of hydrogen fuel cell, hydrogen storage and delivery, fluidic interconnects and power conditioning electronics required for creating high energy density portable power sources. The small size, low heat production, environmental sustainability and refueling flexibility of the systems provides enormous economic opportunities for the use of micro hydrogen in cell phone technology, personal digital assistants and other electronic gadgets. Details of a trial to test and evaluate micro hydrogen fuel cell powered bike lights were presented. Further programs are planned for external demonstrations of high-beam search and rescue lighting, flashlights for security personnel and portable hydrogen power sources that will be used by multiple organizations throughout British Columbia. It was concluded that fuel cell technology must match the lithium-ion battery's performance by providing fast recharge, high energy density, and adaptability. Issues concerning refueling and portable and disposable cartridges for micro hydrogen systems were also discussed. 8 figs.

    Medical students often study only to fare well in their examinations or pursue a specific specialty, or study only those topics that they perceive to be useful in medical practice. The motivation for study in these cases comes from external or internal pressures or from the desire to obtain rewards. Self-determination theory (SDT) classifies this type of motivation as controlled motivation and the type of motivation that comes from genuine interest or personal value as autonomous motivation. Autonomous motivation, in comparison with controlled motivation, has been associated with better learning, academic success, and less exhaustion. SDT endorses autonomous motivation and suggests that autonomy support is important for autonomous motivation. The meaning of autonomy is misinterpreted by many. This article tries to focus on how to be autonomy-supportive in medical education. Autonomy support refers to the perception of choice in learning. Some of the ways of supporting autonomy in medical education are small group teaching, problem-based learning, and gradual increase in responsibility of patients. Autonomy-supportive teaching behavior is not a trait and can be learned. Autonomy support in medical education is not limited to bringing in changes in the medical curriculum for students; it is about an overall change in the way of thinking and working in medical schools that foster autonomy among those involved in education. Research into autonomy in medical education is limited. Some topics that need to be investigated are the ideas and perceptions of students and teachers about autonomy in learning. Autonomy support in medical education can enhance autonomous motivation of students for medical study and practice and make them autonomy-supportive in their future medical practice and teaching.

    2010-07-01

    In recent years, due to population growth, the numbers of enrolled students in Mansoura University, Egypt, has significantly increased, leading to a lack of library space. As a solution to this issue, the aim of this paper is to present the design procedures for building a portable library. The process consists of conducting a feasibility study, then identifying the most relevant parameters and using a software to create an energy efficient structure. A case study was conducted in Mansoura University on a portable library measuring 6.60mx9.90mx4.20m; simulations were carried out with the Ecotect simulation software. Results showed that the proposed methodology was successful in designing a portable library and that it allowed a reduction in energy consumption of 40% compared to the baseline case. This paper provided design guidelines for the construction of portable libraries through the use of transient building performance.

  10. Adolescent autonomy revisited: clinicians need clearer guidance.

    Science.gov (United States)

    Brierley, Joe; Larcher, Victor

    2016-08-01

    In 1996, Brazier and Bridge raised the question 'is adolescent autonomy truly dead and buried' following judicial decisions which had seemed to reverse the Gillick-inspired trend for greater child autonomy in healthcare. Subsequent decisions by the courts have reinforced the view that those below 18 years in England and Wales remain children with limited rights to refuse treatment compared with adults. This is at variance with the daily experience of those working with young people who increasingly seek to actively involve them in making freely informed decisions about their healthcare, in accordance with the principles enunciated in the UN Convention of the Rights of the Child and the UK Children Acts. We review the derivation of the law in England and Wales in this area, in the light of another recent family court judgement enforcing treatment on a 'competent' child without his or her consent and ask: 'How can the Common Law and the ethical practice of those caring for young people have diverged so far?' Either young people can decide whether to have a recommended treatment, or they cannot. Given Ian McEwan's book, the Children Act, has stimulated wider social debate in this area might this be an opportune moment to seek public policy resolution with regards to healthcare decision making by young people? We argue that events since the Gillick case have underlined the need for a comprehensive review of legal policy and practice in this area. While absolute autonomy and freedom of choice are arguably inconsistent with the protection rights that society has agreed are owed to children, healthcare practitioners need clarity over the circumstances in which society expects that autonomous choices of adolescents can be overridden.

    High levels of experienced job autonomy are found to be beneficial for healthcare professionals and for the relationship with their patients. The aim of this study was to assess how maternity care professionals in the Netherlands perceive their job autonomy in the Dutch maternity care system and whether they expect a new system of integrated maternity care to affect their experienced job autonomy. A cross-sectional survey. The Leiden Quality of Work Life Questionnaire was used to assess experienced job autonomy among maternity care professionals. Data were collected in the Netherlands in 2015. 799 professionals participated of whom 362 were primary care midwives, 240 obstetricians, 93 clinical midwives and 104 obstetric nurses. The mean score for experienced job autonomy was highest for primary care midwives, followed by obstetricians, clinical midwives and obstetric nurses. Primary care midwives scored highest in expecting to lose their job autonomy in an integrated care system. There are significant differences in experienced job autonomy between maternity care professionals. When changing the maternity care system it will be a challenge to maintain a high level of experienced job autonomy for professionals. A decrease in job autonomy could lead to a reduction in job related wellbeing and in satisfaction with care among pregnant women. Copyright © 2017. Published by Elsevier Ltd.

  12. Autonomy and reason: treatment choice in breast cancer.

    Twomey, Mary

    2012-10-01

    The practice of offering choice to those women with breast cancer for whom either breast conserving surgery or mastectomy would be equally beneficial has come to be seen as an important aspect of medical care. As well as improving satisfaction with treatment, this is seen as satisfying the ethical principle of respect for autonomy. A number of studies, however, show that women are not always comfortable with such choice, preferring to leave treatment decisions to their surgeons. A question then arises as to the extent that these women can be seen as autonomous or as exercising autonomy. This paper argues, however, that the understanding of autonomy which is applied in current approaches to breast cancer care does not adequately support the exercise of autonomy, and that the clinical context of care means that women are not able to engage in the kind of reasoning that might promote the exercise of autonomy. Where respect for autonomy is limited to informed consent and choice, there is a danger that women's interests are overlooked in those aspects of their care where choice is not appropriate, with very real, long-term consequences for some women. Promoting the exercise of autonomy, it is argued, needs to go beyond the conception of autonomy as rational individuals making their own decisions, and clinicians need to work with an understanding of autonomy as relational in order to better involve women in their care. © 2012 Blackwell Publishing Ltd.

  13. [Autonomy: to what extent is the concept relevant in psychiatry?].

    de Wit, F A

    2012-01-01

    Autonomy is an important concept in psychiatry, but because it is a somewhat abstract and ambiguous notion, it is not applicable in its entirety in a psychiatric context. This becomes obvious in situations where patients are receiving long term care and treatment. To modify the concept of autonomy in such a way that it acquires an extra dimension that renders it applicable to daily psychiatric practice. The literature was reviewed in order to find articles that reveal the tensions that arise between autonomy and dependence in psychiatry and that reflect the human characteristics that are concealed behind the modern concepts of autonomy, freedom and respect for autonomy. Concepts such as person, identity, acknowledgement, dialogical ethics and life histories are used as an addition to the concepts of autonomy of Kant and Mill. A phenomenological and a context sensitive conception of autonomy is needed within the perspective of dialogical ethics. A dialogical perspective requires from psychiatric professionals a susceptibility for what the patient as a human being really has to say. On the basis of a dialogue where there is space and attention for life histories, backgrounds and the potentials of patients, a new perspective can be developed that is shared by the persons involved. In psychiatry, statements about real autonomy and genuine respect for autonomy are only truly meaningful within the context of doctors, nurses and patients. A hermeneutic approach to patients which involves dialogue creates new opportunities in the field of staff-patient relations.

    This paper is a report of an analysis of the concept of patient autonomy Many problems regarding patient autonomy in healthcare contexts derive from the patient's dependent condition as well as the traditional authoritarian position of healthcare professionals. Existing knowledge and experience reveal a lack of consensus among nurses regarding the meaning of this ethical concept. Concept analysis. Medline, CINAHL, The Cochrane Library and PsycINFO were searched (2005-June 2013) using the search blocks 'autonomy', 'patient' and 'nursing/caring'. A total of 41 articles were retrieved. The Evolutionary Method of Concept Analysis by Rodgers was used to identify and construct the meaning of the concept of patient autonomy in a caring context. Five attributes were identified, thus creating the following descriptive definition: 'Patient autonomy is a gradual, time-changing process of (re-)constructing autonomy through the interplay of to be seen as a person, the capacity to act and the obligation to take responsibility for one's actions'. Patient vulnerability was shown to be the antecedent of patient autonomy and arises due to an impairment of a person's physical and/or mental state. The consequences of patient autonomy were discussed in relation to preserving control and freedom. Patient autonomy in a caring context does not need to be the same before, during and after a care episode. A tentative model has been constructed, thus extending the understanding of this ethical concept in a caring context. © 2014 John Wiley & Sons Ltd.

    To realize portable device with high contrast imaging capability, we designed a quantitative phase microscope using transport of intensity equation method based on a smartphone. The whole system employs an objective and an eyepiece as imaging system and a cost-effective LED as illumination source. A 3-D printed cradle is used to align these components. Images of different focal planes are captured by manual focusing, followed by calculation of sample phase via a self-developed Android application. To validate its accuracy, we first tested the device by measuring a random phase plate with known phases, and then red blood cell smear, Pap smear, broad bean epidermis sections and monocot root were also measured to show its performance. Owing to its advantages as accuracy, high-contrast, cost-effective and portability, the portable smartphone based quantitative phase microscope is a promising tool which can be future adopted in remote healthcare and medical diagnosis.

    The disease of critically ill patients was with rapid changes, and at any time faced the risk of emergency. The current commonly used rescue vehicles were larger and bulky implementation, which were not conducive to the operation, therefore the design of a portable rescue vehicle was needed. This new type of rescue vehicle is multi-layer folding structure, with small footprint, large storage space, so a variety of first aid things can be classified and put, easy to be cleaned and disinfected. In the rescue process, the portable rescue vehicles can be placed in the required position; box of various emergency items can be found at a glance with easy access; the height of the infusion stand can adjust freely according to the user height; the rescue vehicle handle can be easy to pull and adjust accord with human body mechanics principle. The portable rescue vehicle facilitates the operation of medical staff, and is worthy of clinical application.

    Full Text Available Un groupe est autonome lorsqu'il prend lui-même en charge sa gestion (Abric, 1996 et lorsque celle-ci fonctionne bien. L'autonomie du groupe restreint est une caractéristique revendiquée dans le cadre actuel de l'expansion de dispositifs collaboratifs à distance entre apprenants. La question qui se pose alors est de savoir si un groupe restreint autonome est plus performant qu'un groupe moins autonome. L'autonomie d'un groupe d'apprentissage en ligne est-elle en relation avec la qualité de la réalisation de la tâche ? Est-elle en relation avec les progrès réalisés par les membres du groupe ? Dans le cadre de notre étude expérimentale, menée dans deux dispositifs pédagogiques différents (l'environnement d'apprentissage Babbelnet et une formation sur la plate-forme Acolad, des étudiants ont réalisé en groupes restreints, avec l'accompagnement d'un tuteur, une tâche de type actionnel – en l'occurrence une rédaction en langue étrangère (allemand ou anglais. Pour ce faire, ils disposaient d'aides méthodologiques et linguistiques dans l'environnement pédagogique en ligne. Ils ont interagi par le biais d'Internet au moyen de différents outils de communication. Une analyse de l'interaction qui a eu lieu dans chaque groupe, l'évaluation des rédactions réalisées conjointement, deux tests réalisés respectivement avant et après la phase de travail en groupe ainsi qu'un formulaire auto-administré nous permettent de mettre en lien l'autonomie des groupes, d'une part, et leur performance, voire leur apprentissage, d'autre part. Au vu de cette étude, il apparaît que l'autonomie du groupe n'a pas d'influence directe sur l'apprentissage des groupes restreints. En revanche, un rapport est visible entre l'appréciation du fonctionnement du groupe par ses membres et l'évolution de la performance des groupes.

    Full Text Available Abstract The mechanism of establishing trust in a computing platform is tightly coupled with the characteristics of a specific machine. This limits the portability and mobility of trust as demanded by many emerging applications that go beyond the organizational boundaries. In order to address this problem, we propose a mobile and portable trusted computing platform in a form of a USB device. First, we describe the design and implementation of the hardware and software architectures of the device. We then demonstrate the capabilities of the proposed device by developing a trusted application.

  2. Conception of modular hydrogen storage systems for portable applications

    Paladini, V.; Miotti, P.; Manzoni, G.; Ozebec, J.

    2003-01-01

    Hydrogen, till now the most prominent candidate as a future sustainable energy carrier, yields a gravimetric energy density three times as high as liquid hydrocarbon. Furthermore it is proven to be the most environmentally friendly fuel. Unfortunately, a few components regarding storage and tank solutions have not yet reached a technology level required for broad use. Thus, we intend to propose solutions and device concepts for both devices everyday use and space applications. This contribution assesses both state of the art of storage materials and existing technologies of power generation systems for application in portable devices. The aim of this work is to define the characteristics of a modular system, being suitable for a wide range of different devices, operating on advanced metal hydrides as the active hydrogen supply component. The concept has been studied and modelled with respect to volumes, mass and power requirements of different devices. The smallest system developed is intended to run, for example, a mobile phone. Minor tuning and straightforward scale up of this power supply module should make it suitable for general applicability in any portable device. (author)

  3. Satellite combined heat and power plants and their legal autonomy

    International Nuclear Information System (INIS)

    Loibl, Helmut

    2014-01-01

    Since the landmark decision by the German Court of Justice concerning the term ''plant'' in the context of biogas plants it should be clear beyond doubt that satellite combined heat and power plants (CHPs) are legally autonomous plants pursuant to Para. 3 No. 1 of the Renewable Energy Law (EEG). What has yet to be finally resolved are the conditions under which satellite CHPs are to be regarded as autonomous. This will be a question of distance on the one hand and of operation autonomy on the other. In the individual case both these factors will have to be assessed from the perspective of an average objective, informed citizen. To the extent that its heat and electricity are being utilised in a meaningful manner, the plant's autonomy will be beyond doubt, at least in operational terms. Regarding the remuneration to be paid for satellite CHPs the only case requiring special consideration is when a CHP falls under the EEG of 2012. In this case Para. 1 Section 1 Sentence 2 EEG provides that the remuneration for the CHP in question is to be calculated as if there was a single overall plant. To the extent that none of the CHPs fall under the EEG of 2012, the ruling remains that there is a separate entitlement to remuneration for each satellite CHP. This also holds in cases where satellite CHPs that were commissioned after 1 January 2012 are relocated. When a satellite CHP is replaced by a new one, the rate and duration of remuneration remain unchanged. However, when a new satellite CHP is added to an existing satellite CHP via a gas collector line it is to be treated according to the decisions of the Federal Court of Justice concerning biogas plant extensions: It falls under the law that applies to the existing CHP and has an entitlement to a new minimum remuneration period, albeit subject to the degression rate provided by the EEG version in question.

    There is concern about graduating thoracic trainees' independent operative skills due to limited autonomy in training. This study compared faculty and trainee expected levels of autonomy with intraoperative measurements of autonomy for common cardiothoracic operations. Participants underwent frame-of-reference training on the 4-point Zwisch scale of operative autonomy (show and tell → active help → passive help → supervision only) and evaluated autonomy in actual cases using the Zwisch Me!! mobile application. A separate "expected autonomy" survey elicited faculty and resident perceptions of how much autonomy a resident should have for six common operations: decortication, wedge resection, thoracoscopic lobectomy, coronary artery bypass grafting, aortic valve replacement, and mitral valve repair. Thirty-three trainees from 7 institutions submitted evaluations of 596 cases over 18 months (March 2015 to September 2016). Thirty attendings subsequently provided their evaluation of 476 of those cases (79.9% response rate). Expected autonomy surveys were completed by 21 attendings and 19 trainees from 5 institutions. The six operations included in the survey constituted 47% (226 of 476) of the cases evaluated. Trainee and attending expectations did not differ significantly for senior trainees. Both groups expected significantly higher levels of autonomy than observed in the operating room for all six types of cases. Although faculty and trainees both expect similar levels of autonomy in the operating room, real-time measurements of autonomy show a gap between expectations and reality. Decreasing this gap will require a concerted effort by both faculty and residents to focus on the development of independent operative skills. Copyright © 2017 The Society of Thoracic Surgeons.

  7. Bankruptcy Prediction Based on the Autonomy Ratio

    Directory of Open Access Journals (Sweden)

    Daniel Brîndescu Olariu

    2016-11-01

    Full Text Available The theory and practice of the financial ratio analysis suggest the existence of a negative correlation between the autonomy ratio and the bankruptcy risk. Previous studies conducted on a sample of companies from Timis County (largest county in Romania confirm this hypothesis and recommend the autonomy ratio as a useful tool for measuring the bankruptcy risk two years in advance. The objective of the current research was to develop a methodology for measuring the bankruptcy risk that would be applicable for the companies from the Timis County (specific methodologies are considered necessary for each region. The target population consisted of all the companies from Timis County with annual sales of over 10,000 lei (aprox. 2,200 Euros. The research was performed over all the target population. The study has thus included 53,252 yearly financial statements from the period 2007 – 2010. The results of the study allow for the setting of benchmarks, as well as the configuration of a methodology of analysis. The proposed methodology cannot predict with perfect accuracy the state of the company, but it allows for a valuation of the risk level to which the company is subjected.

  8. Mount Athos: Between autonomy and statehood

    Directory of Open Access Journals (Sweden)

    Avramović Dragutin

    2013-01-01

    Full Text Available Legal status of the Mount Athos is characterized by many special features that make it internationally unique legal regime. The author analyzes peculiarities of Mount Athos territorial status, legal position of residents and visitors, as well as organization of Mount Athos authorities. The author concludes that the Mount Athos is characterized by a kind of para-sovereignty. Its autonomy involves not only the internal organization, autonomous governance and religious autonomy, but it also includes many elements of secular life of their visitors. Mount Athos has its own, separate legislative, administrative and judicial powers, while the Statute of the Mount Athos has greater legal force than all the other laws of the Greek state, because the state can not unilaterally change its provisions. Having in mind that the wide self-government is vested in church authorities and that the monks have very specific way of living, the author takes a position that the Mount Athos represent 'monastic state', but without statehood. The author also states that the Mount Athos will be faced with many challenges in the context of spreading of an assimilating, universal conception of human rights.

    Santa Rosa, Bárbara; Corte-Real, Francisco; Vieira, Duarte Nuno

    2013-01-01

    Child custody decisions are among the most difficult for judges to make. The possibility of child abuse allegations or parents' deviant/ psychopathologic behaviours within this context, make the decision further complicated. Based on jurisprudence the listening of children opinion is a way to protect their best interest. In fact children have the right to express an opinion in all matters affecting their life. It should be given proper consideration to children opinion according with his/her age and maturity. Nonetheless custody disputes are emotionally draining issues. Asking the child to express an opinion during a public hearing, most likely in the presence of both parents, its not recommended because this is a potential stressful experience. Child interviews should take place in a proper environment and be set to their age. Medicine and Psychology have an important role in assessing children cognitive, emotional and volitional abilities, which is essential to properly account their opinions according to autonomy degree. This essay analyses the contribution of medico-legal and/or psychological exams to respect the autonomy of the child in cases of regulation of parental responsibilities. The conclusion is the need to establish a symbiotic relationship between the medical and legal perspectives of the (open) concept of child's best interests.

    In this review, we present person-transportable laser induced breakdown spectroscopy (LIBS) devices that have previously been developed and reported in the literature as well as their applications. They are compared with X-ray fluorescent (XRF) devices, which represent their strongest competition. Although LIBS devices have advantages over XRF devices, such as sensitivity to the light elements, high spatial resolution and the possibility to distinguish between different layers of the sample, there are also disadvantages and both are discussed here. Furthermore, the essential portable LIBS instrumentation (laser, spectrograph and detector) is presented, and published results related to new laser sources (diode-pumped solid-state, microchip and fiber lasers) used in LIBS are overviewed. Compared to conventional compact flashlamp pumped solid-state lasers, the new laser sources provide higher repetition rates, higher efficiency (less power consumption) and higher beam quality, resulting in higher fluences, even for lower energies, and could potentially increase the figure of merit of portable LIBS instruments. Compact spectrometers used in portable LIBS devices and their parts (spectrograph, detector) are also discussed. - Highlights: • Overview of portable LIBS devices transportable by a person • Discussion and new trends about portable LIBS instrumentation: laser, spectrograph and detector • Overview of applications of DPSS, microchip and fiber lasers in LIBS.

    The industrial meters with encapsulated sources are used intensely in the present time due to the economic benefits that generate. Their use in all the one world has been reflected in an improvement of the quality of the analyzed product and of one optimization of the production process, allowing to carry out these measurements and controls without interrupting the process and in non destructive form generating an energy saving in turn and of materials. Although these industrial meters are intrinsically safe for design in the portable meters their safety also is strongly governed in the strict pursuit of procedures and in the adequate personnel's training that operate these equipment. In the Argentine Republic in 2005 the Nuclear Regulatory Authority (RNA) had registered a quantity of 160 portable equipment. In the period 1995-2003, 2 incidents took place with these equipment one of them used to measure soils humidity of Troxler trademark containing a source of Am-241(Be) of 370 MBq and the remaining one also of Troxler trademark used to measure density and humidity of soils containing 2 sources of Cs-137 of 296 MBq and Am-241(Be) of 1.48 GBq respectively. The incidents were developed without relevant radiological implications had taken place. In this work those mentioned incidents are analyzed in order to determining the causes that originated the same ones, for this way to be able to elaborate recommendations with the purpose of to correct errors and to diminish the recurrence probability improving the safety in the use of these equipment. From the analyses of these incidents result that should put on more emphasis in the personnel training and the invigoration of the safety culture in the use of the industrial meters. Also a present panorama of the inventory of equipment, sources and users that possess these portable meters in the Argentine Republic is also presented. (Author)

    The use of Energy Dispersive X-Ray Fluorescence (EDXRF) for analysis of environmental samples has gained expressive attention in the last years. With the objective of identification and quantification of heavy metals in water, EDXRF methodology with portable equipment was employed. The work consisted on the use of a portable EDXRF system constituted by a X-ray tube to excite the samples, a Si-Pin detector, a holder for the excitation-detection system and samples positioning, with the standard data acquisition electronics to register the spectra. The samples were filtered in ester cellulose membranes for suspended particulate matter retention. After this, Ammonium Pyrrolidine Dithiocarbamate (APDC) precipitation methodology was applied for sample preconcentration with posterior filtering in membranes. So, the dissolved and non dissolved metal fractions were determined separately. The detection limits were, in mg L -1 : 0.006 (Fe), 0.015 (Co), 0.004 (Cu), 0.002 (Zn), 0.004 (Se) and 0.005 (Pb), with 5% deviations for 95% of confidence. Considering all the sampling locations, it was possible to quantify the following range of concentrations, in mg L -1 : Ca (0.043 - 0.021), Ti (0.137 - 0.014), Mn (0.052 - 0.008), Fe (1.66 - 0.035), Ni (0.012 - 0.010), Cu (0.010 - 0.007), Zn (0.070 - 0.007) and Pb (0.85 - 1.01). The results presented relative deviation from 5% to 22%, within 95% of confidence level, which is considered very satisfactory when using portable equipment. In 4 h of field work it was possible to filter 14 membranes and measure around 16 samples. (author)

    Miniaturized mass spectrometry (MMS) is optimal for a wide variety of applications that benefit from field-portable instrumentation. Like MMS, field asymmetric ion mobility spectrometry (FAIMS) has proven capable of providing in situ analysis, allowing researchers to bring the lab to the sample. FAIMS compliments MMS very well, but has the added benefit of operating at atmospheric pressure, unlike MS. This distinct advantage makes FAIMS uniquely suited for portability. Since its inception, FAIMS has been envisioned as a field-portable device, as it affords less expense and greater simplicity than many similar methods. Ideally, these are simple, robust devices that may be operated by non-professional personnel, yet still provide adequate data when in the field. While reducing the size and complexity tends to bring with it a loss of performance and accuracy, this is made up for by the incredibly high throughput and overall convenience of the instrument. Moreover, the FAIMS device used in the field can be brought back to the lab, and coupled to a conventional mass spectrometer to provide any necessary method development and compound validation. This work discusses the various considerations, uses, and applications for portable FAIMS instrumentation, and how the future of each applicable field may benefit from the development and acceptance of such a device.

    2012-01-01

    Field Portable Energy Dispersive X Ray Fluorescence (FP-EDXRF) is particularly useful to analyze works of art, mainly because of his noninvasive and multielemental capability. In many situations FP-EDXRF is the only non invasive technique that can be realistically used to gain some information about the chemical composition of precious and unique objects. Many kind of works, such as paintings, bronzes, precious metals alloys, inks, stones, stamps and more can be studied using a field portable EDXRF system. This manuscript highlights some drawbacks that have to be kept in mind to fulfill a valid measurement such as the need for other backup methods to support portable XRF results or the problem of the non-homogeneity of the sample. This manuscript will also present three examples to demonstrate the usefulness of FP-EDXRF with paintings on canvas, ancient bronzes and sulfur surface analyses.

  19. The Need for Authenticity-Based Autonomy in Medical Ethics.

    Science.gov (United States)

    White, Lucie

    2017-08-11

    The notion of respect for autonomy dominates bioethical discussion, though what qualifies precisely as autonomous action is notoriously elusive. In recent decades, the notion of autonomy in medical contexts has often been defined in opposition to the notion of autonomy favoured by theoretical philosophers. Where many contemporary theoretical accounts of autonomy place emphasis on a condition of "authenticity", the special relation a desire must have to the self, bioethicists often regard such a focus as irrelevant to the concerns of medical ethics, and too stringent for use in practical contexts. I argue, however, that the very condition of authenticity that forms a focus in theoretical philosophy is also essential to autonomy and competence in medical ethics. After tracing the contours of contemporary authenticity-based theories of autonomy, I consider and respond to objections against the incorporation of a notion of authenticity into accounts of autonomy designed for use in medical contexts. By looking at the typical problems that arise when making judgments concerning autonomy or competence in a medical setting, I reveal the need for a condition of authenticity-as a means of protecting choices, particularly high-stakes choices, from being restricted or overridden on the basis of intersubjective disagreement. I then turn to the treatment of false and contestable beliefs, arguing that it is only through reference to authenticity that we can make important distinctions in this domain. Finally, I consider a potential problem with my proposed approach; its ability to deal with anorexic and depressive desires.

Learner autonomy through a focus on learner reflection and taking responsibility for one’s own learning processes has become a central concern in the recent history of language teaching. However, many language teachers, who are committed to concepts of learnercentredness and autonomy, struggle with the ways to foster learner autonomy or at least to encourage the idea of learner autonomy in language classroom. The study aims at investigating what the most important issues which have a great impact on developing learner autonomy are. Having given special attention to conditions which can insure development of learner autonomy, a model covering seven issues relating to the subject matter has been designed. The authors state that such aspects as choice, goals and needs, support, emotional climate, learning strategies, learner attitude and motivation, and self-esteem should be considered as the goal to promote learner autonomy in EFL context.

    Full Text Available The study examined the applicability of the observational technique developed by Allen and colleagues (Allen, Hauser, Bell, & O’Connor, 1994; Allen, Hauser, et al., 2003 to investigate the issues of autonomy and relatedness in parent-adolescent relationship in the Italian context. Thirty-five mother-adolescent dyads participated to a task in which they discussed a family issue about which they disagree. Adolescents were also administered a self-report measure assessing their relationship with mothers. Mothers reported significantly higher levels of promoting and inhibiting autonomy, and promoting relatedness behaviors than their children. Results also suggested a partial behavioral reciprocity within the dyads, regarding promoting and inhibiting relatedness, and inhibiting autonomy. Finally, mothers’ inhibiting autonomy behaviors positively correlated to teens’ perception of their relationship as conflicting; adolescents’ inhibiting and promoting autonomy and inhibiting relatedness behaviors positively correlated to open confrontation, rejection and coolness, while promoting relatedness behaviors negatively correlated to open confrontation, rejection and coolness. The results suggest that, for Italian mothers, behaviors linked to autonomy seem to be associated with being involved in a more negative relationship with their children, even if not characterized by open hostility, while for Italian adolescents, behaviors linked to autonomy seem to be associated with threatening the closeness of the relationship. Globally, the findings suggest that the application of this observational procedure may help our understanding of youth autonomy and relatedness development in Italy, but they leave unanswered questions regarding its appropriate adaptation and the role played by cultural differences.

    1969-05-15

    The paper describes a portable battery-operated radiation survey meter for monitoring a wide range of X- and gamma-ray exposure rates from 1 mR/h to 100 R/h. The instrument Incorporates a halogen GM tube as the detector and a count-rate meter for indication. A transistorized d.c. -d.c. converter supplies the necessary high voltage to the GM counter. The instrument response has been made energy independent in the energy range 80 keV to 1.25 MeV. Further, the response is linear over the entire range of exposure rates. Suitable extension rods have been designed to provide sufficient separation between the probe and the meter in cases where remote monitoring is necessary because of high fields. (author)

  15. Operating experience of a portable thermophotovoltaic power supply

    Science.gov (United States)

    Becker, Frederick E.; Doyle, Edward F.; Shukla, Kailash

    1999-03-01

    Two configurations of man-portable thermophotovoltaic (TPV) power supplies based on Thermo Power's supported continuous fiber emitter have been designed, built, and are being tested. The systems use narrow-band, fibrous, ytterbia emitters radiating to bandgap matched silicon photovoltaic arrays with dielectric stack filters for optical energy recovery and recuperators for thermal energy recovery. The systems have been designed for operation with propane and with combustion air preheat temperatures of up to 1250 K. To operate at air preheat temperatures above the auto-ignition temperature of the fuel, a unique fuel delivery system was devised which results in the micromixing and rapid combustion of the fuel and air right in the emitter fibers. This allows the ytterbia emitter fibers to run much hotter (˜2000 K) than any of the surrounding structure.

  16. Portable Weather Applications for General Aviation Pilots.

    Ahlstrom, Ulf; Ohneiser, Oliver; Caddigan, Eamon

    2016-09-01

    The objective of this study was to examine the potential benefits and impact on pilot behavior from the use of portable weather applications. Seventy general aviation (GA) pilots participated in the study. Each pilot was randomly assigned to an experimental or a control group and flew a simulated single-engine GA aircraft, initially under visual meteorological conditions (VMC). The experimental group was equipped with a portable weather application during flight. We recorded measures for weather situation awareness (WSA), decision making, cognitive engagement, and distance from the aircraft to hazardous weather. We found positive effects from the use of the portable weather application, with an increased WSA for the experimental group, which resulted in credibly larger route deviations and credibly greater distances to hazardous weather (≥30 dBZ cells) compared with the control group. Nevertheless, both groups flew less than 20 statute miles from hazardous weather cells, thus failing to follow current weather-avoidance guidelines. We also found a credibly higher cognitive engagement (prefrontal oxygenation levels) for the experimental group, possibly reflecting increased flight planning and decision making on the part of the pilots. Overall, the study outcome supports our hypothesis that portable weather displays can be used without degrading pilot performance on safety-related flight tasks, actions, and decisions as measured within the constraints of the present study. However, it also shows that an increased WSA does not automatically translate to enhanced flight behavior. The study outcome contributes to our knowledge of the effect of portable weather applications on pilot behavior and decision making. © 2016, Human Factors and Ergonomics Society.

    2016-03-01

    This integrative review of the existing literature was conducted to identify dimensions related to nurse practitioner (NP) autonomy and to recommend future areas of research related to the important topic of NP autonomy in this era of cost-conscious healthcare reform. Articles were identified from the following databases: CINAHL, MEDLINE, PubMed, Ovid, Scopus, Google Scholar, and EBSCO. Over 24 articles were found; 12 peer-reviewed articles met the inclusion criteria of research conducted with NPs, physicians, and patients. The results revealed three categories of association with regard to NP autonomy: job satisfaction, patient satisfaction, and physician-NP collaboration. This review was undertaken to advance understanding of autonomy among NPs and the dynamics involved in their delivery of care. Further research into the associations between NP autonomy and its dimensions are necessary to indicate a future direction to the NP role. ©2015 American Association of Nurse Practitioners.

    Todorović Zoran M.

    2017-01-01

    Full Text Available Patient autonomy has been a cornerstone of contemporary clinical ethics since the Nuremberg trial, especially in American school of bioethics. Topic: Patient autonomy has been defined in the Nuremberg Code, and re-defined in the Declaration of Helsinki, Belmont Report and Barcelona Declaration. Founders and followers of the rights-oriented bioethics (for example, Hellegers, Beauchamp and Childers have established and promoted the patient autonomy as the main principle of bio(medical ethics since 1970s. However, there is a lot of controversy surrounding such a principle, especially in vulnerable patients. We aimed at evaluating the real meaning and value of patient autonomy in critical care settings regarding the communication between health workers and their patients and families. Conclusion: Protection of patients autonomy in critically ill is a complex issue. Careful benefit-risk assessment is needed in order to find the most appropriate way of obtaining the informed consent, proxy consent or to omit or delay it.

  7. [Psychiatric advance directives and the role of autonomy].

    Science.gov (United States)

    Ambrosini, Daniel L; Crocker, Anne G

    2009-01-01

    Although psychiatric advance directives (PADs) are grounded in the ethics of autonomy, the relationship between the two is unclear. PADs are legal documents that allow individuals with mental illness to record their treatment preferences should they become incompetent in the future. The relationship between autonomy and PADs has been discussed in ethical, legal, and philosophical terms, but has not been clearly operationalized for clinical purposes. Autonomy is a fundamental ethical value that includes having the independence from outside controlling influences and the mental capacity to direct one's personal actions. Individuals with mental illness sometimes require assistance to understand their ethical and legal rights with respect to autonomous choice, and professional stakeholders need education regarding the importance of autonomy for clinical practice. Competency to consent to treatment is the mental prerequisite that ensures individuals with mental illness are able to complete PADs with insight, whereas autonomy is the value that empowers individuals to work towards their recovery.

  8. Intelligent autonomy for unmanned naval systems

    Steinberg, Marc

    2006-05-01

    This paper provides an overview of the development and demonstration of intelligent autonomy technologies for control of heterogeneous unmanned naval air and sea vehicles and describes some of the current limitations of such technologies. The focus is on modular technologies that support highly automated retasking and fully autonomous dynamic replanning for up to ten heterogeneous unmanned systems based on high-level mission objectives, priorities, constraints, and Rules-of-Engagement. A key aspect of the demonstrations is incorporating frequent naval operator evaluations in order to gain better understanding of the integrated man/machine system and its tactical utility. These evaluations help ensure that the automation can provide information to the user in a meaningful way and that the user has a sufficient level of control and situation awareness to task the system as needed to complete complex mission tasks. Another important aspect of the program is examination of the interactions of higher-level autonomy algorithms with other relevant components that would be needed within the decision-making and control loops. Examples of these are vision and other sensor processing algorithms, sensor fusion, obstacle avoidance, and other lower level vehicle autonomous navigation, guidance, and control functions. Initial experiments have been completed using medium and high-fidelity vehicle simulations in a virtual warfare environment and inexpensive surrogate vehicles in flight and in-water demonstrations. Simulation experiments included integration of multi-vehicle task allocation, dynamic replanning under constraints, lower level autonomous vehicle control, automatic assessment of the impact of contingencies on plans, management of situation awareness data, operator alert management, and a mixed-initiative operator interface. In-water demonstrations of a maritime situation awareness capability were completed in both a river and a harbor environment using unmanned surface

    Accurately resolving the ambient neutron dose equivalent spanning the thermal to 15 MeV energy range with a single configuration and lightweight instrument is desirable. This paper presents the design of a portable, high intrinsic efficiency, and accurate neutron rem meter whose energy-dependent response is electronically adjusted to a chosen neutron dose equivalent standard. The instrument may be classified as a moderating type neutron spectrometer, based on an adaptation to the classical Bonner sphere and position sensitive long counter, which, simultaneously counts thermalized neutrons by high thermal efficiency solid state neutron detectors. The use of multiple detectors and moderator arranged along an axis of symmetry (e.g., long axis of a cylinder) with known neutron-slowing properties allows for the construction of a linear combination of responses that approximate the ambient neutron dose equivalent. Variations on the detector configuration are investigated via Monte Carlo N-Particle simulations to minimize the total instrument mass while maintaining acceptable response accuracy—a dose error less than 15% for bare {sup 252}Cf, bare AmBe, an epi-thermal and mixed monoenergetic sources is found at less than 4.5 kg moderator mass in all studied cases. A comparison of the energy dependent dose equivalent response and resultant energy dependent dose equivalent error of the present dosimeter to commercially-available portable rem meters and the prior art are presented. Finally, the present design is assessed by comparison of the simulated output resulting from applications of several known neutron sources and dose rates.

  10. 500 Watt Diesel Fueled TPV Portable Power Supply

    Horne, W. E.; Morgan, M. D.; Sundaram, V. S.; Butcher, T.

    2003-01-01

    A test-bed 500 watt diesel fueled thermophotovoltaic (TPV) portable power supply is described. The goal of the design is a compact, rugged field portable unit weighing less than 15 pounds without fuel. The conversion efficiency goal is set at 15% fuel energy to electric energy delivered to an external load at 24 volts. A burner/recuperator system has been developed to meet the objectives of high combustion air preheat temperatures with a compact heat exchanger, low excess air operation, and high convective heat transfer rates to the silicon carbide emitter surface. The burner incorporates a air blast atomizer with 100% of the combustion air passing through the nozzle. Designed firing rate of 2900 watts at 0.07 gallons of oil per hour. This incorporates a single air supply dc motor/fan set and avoids the need for a system air compressor. The recuperator consists of three annular, concentric laminar flow passages. Heat from the combustion of the diesel fuel is both radiantly and convectively coupled to the inside wall of a cylindrical silicon carbide emitter. The outer wall of the emitter then radiates blackbody energy at the design temperature of 1400°C. The cylindrical emitter is enclosed in a quartz envelope that separates it from the photovoltaic (PV) cells. Spectral control is accomplished by a resonant mesh IR band-pass filter placed between the emitter and the PV array. The narrow band of energy transmitted by the filter is intercepted and converted to electricity by an array of GaSb PV cells. The array consists of 216 1-cm × 1-cm GaSb cells arranged into series and parallel arrays. An array of heat pipes couple the PV cell arrays to a heat exchanger which is cooled by forced air convection. A brief status of the key TPV technologies is presented followed by data characterizing the performance of the 500 watt TPV system.

  13. Reconceptualizing Autonomy: A Relational Turn in Bioethics.

    Science.gov (United States)

    Jennings, Bruce

    2016-05-01

    History's judgment on the success of bioethics will not depend solely on the conceptual creativity and innovation in the field at the level of ethical and political theory, but this intellectual work is not insignificant. One important new development is what I shall refer to as the relational turn in bioethics. This development represents a renewed emphasis on the ideographic approach, which interprets the meaning of right and wrong in human actions as they are inscribed in social and cultural practices and in structures of lived meaning and interdependence; in an ideographic approach, the task of bioethics is to bring practice into theory, not the other way around. The relational turn in bioethics may profoundly affect the critical questions that the field asks and the ethical guidance it offers society, politics, and policy. The relational turn provides a way of correcting the excessive atomism of many individualistic perspectives that have been, and continue to be, influential in bioethics. Nonetheless, I would argue that most of the work reflecting the relational turn remains distinctively liberal in its respect for the ethical significance of the human individual. It moves away from individualism, but not from the value of individuality.In this review essay, I shall focus on how the relational turn has manifested itself in work on core concepts in bioethics, especially liberty and autonomy. Following a general review, I conclude with a brief consideration of two important recent books in this area: Jennifer Nedelsky's Law's Relations and Rachel Haliburton's Autonomy and the Situated Self. © 2016 The Hastings Center.

  14. Euthanasia--he illusion of autonomy.

    Science.gov (United States)

    Hartling, O J

    2006-03-01

    The paper deals with some of the more common arguments used for the legalisation of voluntary euthanasia. It looks at these arguments from an ethical and philosophical point of view. First, the argument that to offer a person the possibility of euthanasia is to respect that person's autonomy is questionable. Can a person's decision on euthanasia be really autonomous? If euthanasia were legal everybody would be conscious of this option: the patient, the doctor, the family and the nursing staff. Thus, there could be indirect pressure on the patient to make a decision. The choice is meant to be free but the patient is not free not to make the choice. Secondly, a choice that seeks to alleviate suffering and thus improve life by annihilating it is irrational. Thirdly, autonomy as to one's own death is hardly exercised freely. Even an otherwise competent person may not be competent in deciding on his own death on account of despair, hopelessness, fear or maybe a feeling of being weak, superfluous and unwanted. This is a very uncertain base for decision-making, especially in the irrevocable decision of euthanasia. Finally, a competent person usually makes any choice in a responsible way and after due consideration; a 'good' decision should consider and respect the wishes and feelings of others. This will be no less the case in making a decision on the so-called free choice of euthanasia. Thus 'normal' behaviour in decision making will only add to the tendency of the already depressed person to feel a burden on his family, the staff and even on society.

  15. Model Based Autonomy for Robust Mars Operations

    Science.gov (United States)

    Kurien, James A.; Nayak, P. Pandurang; Williams, Brian C.; Lau, Sonie (Technical Monitor)

    1998-01-01

    Space missions have historically relied upon a large ground staff, numbering in the hundreds for complex missions, to maintain routine operations. When an anomaly occurs, this small army of engineers attempts to identify and work around the problem. A piloted Mars mission, with its multiyear duration, cost pressures, half-hour communication delays and two-week blackouts cannot be closely controlled by a battalion of engineers on Earth. Flight crew involvement in routine system operations must also be minimized to maximize science return. It also may be unrealistic to require the crew have the expertise in each mission subsystem needed to diagnose a system failure and effect a timely repair, as engineers did for Apollo 13. Enter model-based autonomy, which allows complex systems to autonomously maintain operation despite failures or anomalous conditions, contributing to safe, robust, and minimally supervised operation of spacecraft, life support, In Situ Resource Utilization (ISRU) and power systems. Autonomous reasoning is central to the approach. A reasoning algorithm uses a logical or mathematical model of a system to infer how to operate the system, diagnose failures and generate appropriate behavior to repair or reconfigure the system in response. The 'plug and play' nature of the models enables low cost development of autonomy for multiple platforms. Declarative, reusable models capture relevant aspects of the behavior of simple devices (e.g. valves or thrusters). Reasoning algorithms combine device models to create a model of the system-wide interactions and behavior of a complex, unique artifact such as a spacecraft. Rather than requiring engineers to all possible interactions and failures at design time or perform analysis during the mission, the reasoning engine generates the appropriate response to the current situation, taking into account its system-wide knowledge, the current state, and even sensor failures or unexpected behavior.

  16. Defining Design Limits of a Portable Radiation Dispersion Prevention System

    2016-05-15

    To the eyes of the general public, however, reducing the chance of such accident is not enough. A typical engineer views a risk as a combination of both consequences and likelihoods, whereas an ordinary person may only consider consequences. The implementations of better regulations, improved human operator actions, and installations of extra safety systems may reduce the chance of having uncontrolled accident practically to zero, yet the public still fears having nuclear reactors. One such barrier system is a portable suction-based radiation dispersion prevention system, called Integrated Portable Suction-Centrifugal Filtration System (IPS-CFS). To design such systems, detailed information about the radioactive source term at the release point to the environment must be available to draw design limits. The preliminary design limits of the IPS-CFS are presented in this paper. It may seem challenging to design a comprehensive radioactive dispersion system that can successfully prevent such extreme accident conditions, especially due to the releases from high pressure. However, as more technologies develop and more realistic source term analyses are performed, it may be possible to develop such a public relief technology. With the development of such technology that can effectively prevent the dispersion of the uncontrolled radioactive releases in case of another Fukushima-like accident, it will result in increased safety of the nuclear power plants for both the public and the workers and may contribute to the increase in the public acceptance of nuclear energy.

    This paper covers the innovation of a Heavy Duty Portable Variable Power Supply (HPVPS) in Jabatan Kejuruteraan Elektrik (JKE), Politeknik Mukah, Sarawak (PMU). This project consists of variable power supply which can vary the output from 1.2 V to 11.6V, AC pure wave inverter to convert DC to AC for the operation of low power home appliances and also used Li-on rechargeable batteries to store the electrical energy and additional feature that can be used to jump-start the batteries of the car. The main objective of this project is to make the user can operate the electronic devices anywhere whenever if no electricity while doing their lab activities. Most of the regulated power supply in JKE lab aged 9-10 years old and need periodical maintenance and need cost and also the unit can be used is not enough to support the whole class during lab activities. As a result, the P&P process will be facing the major problem in order to make the lab activities running smoothly. By development of the portable variable power supply, the P&P process is more efficient and very helpful.

    Halbig, J.K.; Klosterbuer, F.; Cameron, R.A.

    1986-01-01

    In 1981 a small, battery-operated multichannel analyzer (MCA) prototype developed at Los Alamos National Laboratory was delivered to the International Atomic Energy Agency (IAEA). The intent was to produce an instrument for inspector (nonscientist) use. Automated measurement programs were built into the MCA. An enhanced, commercially produced MCA is now available, which was patterned after and is software compatible with the prototype. After an extensive review of the hardware and software of the available portable MCAs, the IAEA has chosen this MCA to be used by IAEA inspectors throughout the world. Inspectors from the EURATOM Directorate of Safeguards are also using these MCAs in inspections throughout Europe. While this MCA's portability and programmability make it ideally suited for infield applications, its powerful built-in intelligence and communications protocol make it a strong candidate for distributed data acquisition and control systems. The user-instrument interface philosophy is so easy to use that in domestic and international training schools, the operators manual is not used

    A new portable solar generator has been developed to generate electricity. It has the potential to replace petrol generator, widely used by peddlers at night markets (pasar malam). Conventional generators are heavy, oily, have high maintenance and use fossil fuel to generate electricity. The solar generator can generate 20 Watts of electricity. This amount of power can supply up to 96 hours of electricity for the purpose of lighting and running small electrical appliances. The power output is (alternating current) AC current using 150 Watts inverter with 200 Watts surge, suitable for all commercial single phase electric appliances. Solar charge controller is used to maximize the charging rate and to protect the battery. The system has low maintenance whereby the batteries need to be changed every three to four years, depending on the usage. The main concepts of portable solar generator are to reduce installation cost and to introduce a compact design of an optimal energy sizing system. The materials used to develop the solar generator can be easily obtained from local markets, thus reducing the cost of developing the system and making it suitable for commercialization.

    Portable bridges serve as routes for troops during the military operations and the disaster relief operation. Nowadays, bamboo has been regarded as one of the alternative construction materials for building and bridge structures. This paper presents the conceptual design of the portable bridge. Several types of portable bridges and bamboo bridges are reviewed in the current work. The characteristics, capability and method of construction of each bridge are discussed. Finally, the conceptual of the portable bamboo bridge for emergency purposes is presented. The idea of producing portable bridge is proposed in the current work as it is crucial for providing route for communities affected by natural disasters.

  1. Technical testing of portable isotope identification instruments

    2001-01-01

    . First generation portable isotope identifiers were identified and evaluated by U.S. Customs. Instruments from five vendors were put through a battery of tests according to delineated test procedures. The tests fell into five categories: Basic operation verification; Medical isotope identification; Individual isotope identification; Isotope pair identification; Dose rate calculation. The tests can be summarized as an initial verification of correct instrument operation (including whatever calibration procedure was specified by the vendor), followed by three different isotope identification tests designed to verify the instrument's ability to correctly identify 19 isotopes specified by U.S. Customs. The final test determined each instrument's ability to correctly display the dose rate from a wide energy range of gamma emitters. The individual isotope identification test and the isotope pair identification test were performed with three types of intervening shielding. The first of these three types used the minimum packaging needed for safe source handling and was, in general, thin plastic. This type of shielding is virtually identical to a bare radiation source. The second type of shielding used 2.7 mm of steel to simulate the wall of a typical transportainer (or sea-tainer). The third type of shielding used 6.94 mm of lead to simulate typical industrial packaging or, perhaps, an attempt by the shipper to conceal the source without unduly increasing the weight of the shipment. The isotopes tested were broadly categorized as: Special nuclear material (SNM), Medical, and Industrial. These included 17 gamma emitters, 1 beta emitter, and 1 neutron emitter. Each instrument was subjected to the following testing regimen: First, each instrument was calibrated according to vendor's procedures. Instrument size and weight were recorded. Next, the instrument's response to medical isotopes in their usual shipping containers was measured. This represents the most commonly occurring

  2. Authenticity and autonomy in deep-brain stimulation.

    2014-08-01

    Felicitas Kraemer draws on the experiences of patients undergoing deep-brain stimulation (DBS) to propose two distinct and potentially conflicting principles of respect: for an individual's autonomy (interpreted as mental competence), and for their authenticity. I argue instead that, according to commonly-invoked justifications of respect for autonomy, authenticity is itself in part constitutive of an analysis of autonomy worthy of respect; Kraemer's argument thus highlights the shortcomings of practical applications of respect for autonomy that emphasise competence while neglecting other important dimensions of autonomy such as authenticity, since it shows that competence alone cannot be interpreted as a reliable indicator of an individual's capacity for exercising autonomy. I draw from relational accounts to suggest how respect for a more expansive conception of autonomy might be interpreted for individuals undergoing DBS and in general.

    This paper examines recently admitted nursing home residents' practical autonomy, their remaining social environment and their social functioning. In a cross-sectional design, 391 newly admitted residents of 67 nursing homes participated. All respondents were ≥65 years old, had mini-mental state examination ≥18 and were living in the nursing home for at least 1 month. Data were collected using a structured questionnaire and validated measuring tools. The mean age was 84, 64% were female, 23% had a partner, 80% children, 75% grandchildren and 59% siblings. The mean social functioning score was 3/9 (or 33%) and the autonomy and importance of autonomy score 6/9 (or 67%). More autonomy was observed when residents could perform activities of daily living more independently, and cognitive functioning, quality of life and social functioning were high. Residents with depressive feelings scored lower on autonomy and social functioning compared to those without depressive feelings. Having siblings and the frequency of visits positively correlated with social functioning. In turn, social functioning correlated positively with quality of life. Moreover, a higher score on social functioning lowered the probability of depression. Autonomy or self-determination and maintaining remaining social relationships were considered to be important by the new residents. The remaining social environment, social functioning, quality of life, autonomy and depressive feelings influenced each other, but the cause--effect relation was not clear.

  4. Are there limits to respect for autonomy in bioethics?

    2008-06-01

    I discuss the significance of respect for personal autonomy in bioethics with reference to its practical expression: rational informed patient choice. The question is whether, given the apparent practical limitations to this notion, bioethical autonomy should be seen as an absolute. After a historical review of informed consent and its development, I discuss the requirements for informed consent. Some inherent tensions are evaluated, as is the applicability of the notion that in order to be legitimate, autonomy should do some ethical work. Limits to the notion of informed consent are explored with reference to six examples: the right of women to reproductive autonomy; the autonomy of legally minor Jehovah's Witnesses; autonomy in cosmetic surgery; inappropriate treatment; autonomy and human medical research, and euthanasia and other end-of-life options. The discussion is within a South African framework with reference to other jurisdictions and decisions where appropriate. I conclude that whilst some unusual instances of limitation of bioethical informed consent might be ethically justifiable, the arguments presented point to the opposite: the unfounded limitation of informed consent.

    Although clinicians may value respecting a patient's or surrogate's autonomy in decision-making, it is not always clear how to proceed in clinical practice. The confusion results, in part, from which conception of autonomy is used to guide ethical practice. Reliance on an individualistic conception such as the "in-control agent" model prioritizes self-sufficiency in decision-making and highlights a decision-maker's capacity to have reason transcend one's emotional experience. An alternative model of autonomy, relational autonomy, highlights the social context within which all individuals exist and acknowledges the emotional and embodied aspects of decision-makers. These 2 conceptions of autonomy lead to different interpretations of several aspects of ethical decision-making. The in-control agent model believes patients or surrogates should avoid both the influence of others and emotional persuasion in decision-making. As a result, providers have a limited role to play and are expected to provide medical expertise but not interfere with the individual's decision-making process. In contrast, a relational autonomy approach acknowledges the central role of others in decision-making, including clinicians, who have a responsibility to engage patients' and surrogates' emotional experiences and offer clear guidance when patients are confronting serious illness. In the pediatric setting, in which decision-making is complicated by having a surrogate decision-maker in addition to a patient, these conceptions of autonomy also may influence expectations about the role that adolescents can play in decision-making.

    General practice has been the subject of extensive reforms over the 1990s in Australia as elsewhere. Reforms have attempted to improve quality and contain the overall cost of health care, and have often been seen as reducing the autonomy of medical professionals. This paper examines the impact of financial constraints and incentives introduced during the 1990s on Australian GPs' perceptions of autonomy. An existing seven component definition of autonomy and six themes that emerged from reviewing publications were used to construct focus group questions. A total of 25 GPs participated in four focus groups. Those who participated believe that their financial autonomy has been diminished by policy changes and consumer expectations. They also perceive that their ability to control clinical decisions, which they regard as the most important aspect of professional autonomy, has been reduced along with financial autonomy. Organized medicine in Australia sees financial accountability and clinical decision making as polar opposites, and has continued to argue that fee-for-service payment is the only appropriate method of remuneration, despite increasing evidence that this does not guarantee clinical autonomy. Major changes to the financing of general practice in Australia are required to address the concerns of GPs, governments and patients.

  7. Assessing Ultraviolet Hazards Using Portable Measuring Instruments

    The 'Erythemal Action Spectrum' shows an increase of 10 3 in human skin sensitivity to UV radiation over only 30 nm of change of wavelength, from 328 nm to 298 nm. This represents a severe challenge to the manufacturing and calibration of a portable instrument which can measure the vanishingly small amounts of short wavelength UV from solarium tanning lamps, and to apply accurately an action spectra to be able to quantify the hazard presented by such lamps to skin. The classification of UV lamp types from their 'effective irradiance' requires very sharp discrimination between UV power contained in the short wavelength and the long wavelength parts of the UV spectra, so radiometers give misleading results. The only instrument suitable for making these measurements is the spectroradiometer. The development of such an instrument in a hand held portable form is described, with the difficulties associated with its calibration and such factors as stray light rejection. (author)

    2002-07-01

    This report describes the state-of-the-art of fuel cell technology for portable power applications. The study involved a comprehensive literature review. Proton exchange membrane fuel cells (PEMFCs) have attracted much more interest than either direct methanol fuel cells (DMFCs) or solid oxide fuel cells (SOFCs). However, issues relating to fuel choice and catalyst design remain with PEMFCs; DMFCs have excellent potential provided issues relating to the conducting membrane can be resolved but the current high temperature of operation and low power density currently makes SOFCs less applicable to portable applications. Available products are listed and the obstacles to market penetration are discussed. The main barriers are cost and the size/weight of fuel cells compared with batteries. Another key problem is the lack of a suitable fuel infrastructure.

    Two types of TLD systems are used for environmental dose monitoring. One is based on an NHZ-203 laboratory TLD reader and CaSO/sub 4/:Dy powder. The other is based on CaSO/sub 4/:Tm bulbs and a small, portable TLD reader built into a cross-country car and operated by means of the car battery. The laboratory TLD system has been used for many years for environmental monitoring and it has been tested and proved satisfactory at international intercomparisons for environmental dosemeters. The new portable TLD system has the advantage of being able to establish the dose in a few minutes at the environmental station. The transport dose is omitted as the TLDs are evaluated at the field site. The evaluation of a bulb needs only a few minutes and the measured dose value can be reported back by radio - an important aspect during an emergency situation.

    Argonne National Laboratory, with support from DOE's Office of Nonproliferation and National Security, is currently developing an intelligent hand-portable sensor system. This system is designed specifically to support the intelligence community with the task of in-field sensing of nuclear proliferation and related activities. Based upon pulsed laser photo-ionization time-of-flight mass spectrometry technology, this novel sensing system is capable of quickly providing a molecular or atomic analysis of specimens. The system is capable of analyzing virtually any gas phase molecule, or molecule that can be induced into the gas phase by (for example) sample heating. This system has the unique advantages of providing unprecedented portability, excellent sensitivity, tremendous fieldability, and a high performance/cost ratio. The system will be capable of operating in a highly automated manner for on-site inspections, and easily modified for other applications such as perimeter monitoring aboard a plane or drone. The paper describes the sensing system

  12. Clinical guidelines and the fate of medical autonomy in Ontario.

    Science.gov (United States)

    Rappolt, S G

    1997-04-01

    Conceptually, clinical guidelines and professional autonomy have a paradoxical relationship. Despite being the quintessence of medical knowledge at the corporate level, guidelines diminish the clinical autonomy of individual practitioners, and therefore threaten medicine's justification for its autonomy. Theorists have argued that professional autonomy will be retained through elite dominance of practitioners, while comparative research suggests that economic autonomy can be traded off to retain clinical autonomy. Under government pressure to regulate the growth of Ontario physicians' fee-for-service public expenditure, the profession's representative organization, the Ontario Medical Association (OMA), promoted voluntary clinical guidelines, hoping to both constrain costs and preserve professional control over the content of medical care. The OMA collaborated with the Ministry of Health in developing guidelines and establishing a provincial centre for health service research. Ontario's practitioners disregarded the OMA's exhortations to implement clinical guidelines, suggesting that in the absence of external constraints, practitioners can subvert elite dominance. However, practitioners' unchecked clinical and economic autonomy, combined with evidence of wide provincial variations in medical care, served to legitimize the government's increasingly unilateral control over the schedule of insured medical services, and, in 1993, their imposition of a global cap on physicians' fee-for-service income pool. When analysed in the context of ongoing Ministry-OMA relations, the failure of the OMA's guidelines strategy to constrain medical service costs has expedited an overall decline in medical autonomy in Ontario. The emergence and course of Ontario's clinical guidelines movement is consistent with the view that medical autonomy is contingent upon broad class forces, and the conceptualization of professional organizations as instruments for mediated occupational control.

    This study examined perceived support for autonomy-the extent to which individuals feel empowered and supported to make informed choices-among participants in the Recovery After an Initial Schizophrenia Episode Early Treatment Program (RAISE ETP). The aims of this study were to evaluate whether NAVIGATE, the active treatment studied in RAISE ETP, was associated with greater improvements in perceived autonomy support over the two-year intervention, compared with community care, and to examine associations between perceived autonomy support and quality of life and symptoms over time and across treatment groups. This study examined perceived autonomy support among the 404 individuals with first-episode psychosis who participated in the RAISE ETP trial (NAVIGATE, N=223; community care, N=181). Three-level conditional linear growth modeling was used given the nested data structure. The results indicated that perceived autonomy support increased significantly over time for those in NAVIGATE but not in community care. Once treatment began, higher perceived autonomy support was related to higher quality of life at six, 12, and 18 months in NAVIGATE and at 12, 18, and 24 months in community care. Higher perceived autonomy support was related to improved scores on total symptoms and on excited symptoms regardless of treatment group and time. Overall, perceived autonomy support increased in NAVIGATE but not for those in community care and was related to improved quality of life and symptoms across both treatment groups. Future research should examine the impact of perceived autonomy support on a wider array of outcomes, including engagement, medication adherence, and functioning.

    ASC legacy software must be ported to emerging hardware architectures. This paper notes that many programming models used by DOE applications are similar, and suggests that constructing a common terminology across these models could reveal a performance portable programming model. The paper then highlights how the LULESH mini-app is used to explore new programming models with outside solution providers. Finally, we suggest better tools to identify parallelism in software, and give suggestions for enhancing the co-design process with vendors.

    Is it true that haste is sneaking into medicine? In this article, it is argued that it mainly concerns the perception of being rushed, which is caused by a loss of autonomy of the modern physician. In the fifties, physicians were busy as well, but because they enjoyed a greater degree of autonomy compared to their contemporary colleagues, they did not experience this in a negative way. Due to increased bureaucracy and the introduction of market dynamics, the medical profession has lost autonomy, which in turn led to a loss of job satisfaction.
